    In both North America and Europe, high levels of mercury have been reported in lakes that do not receive obvious point-source mercury inputs. Concern over high contaminant levels in waterfowl and fish have prompted several government-issued advisories on safe levels of fish and wildlife intake for humans. Although the primary source of mercury in pristine lakes is directly through atmospheric deposition or indirectly via terrestrial runoff, there can be large variations in mercury concentrations in organisms in neighbouring lakes. Therefore, factors other than atmospheric deposition must influence bioavailability and accumulation of mercury in aquatic organisms. For that reason, multivariate analyses on benthic invertebrate methylmercury concentrations and water chemistry from 12 Quebec water bodies were used to construct simple, predictive models of benthic invertebrate methylmercury in 23 lakes in Ontario and Quebec. The study showed that the primary means of mercury accumulation for organisms in higher trophic positions is dietary through the assimilation of organic forms of mercury, principally methylmercury. The data from 12 Quebec water bodies, revealed that benthic invertebrates in reservoirs have higher methylmercury than those in natural lakes, and methylmercury is generally higher in predatory invertebrates. Reservoir age was found to correlate with fish, benthic invertebrate methylmercury, and also with lake chemistry parameters such as pH and dissolved organic carbon (DOC). The objective of the study was to determine the appropriate level of taxonomic or functional resolution for generating benthic invertebrate methylmercury models, and to identify which environmental variables correlate most with benthic invertebrate methylmercury. Empirical models using these correlations were constructed and their predicted efficiency was tested by cross-validation. In addition, the effect of exposure to fish digestive enzymes on invertebrate methylmercury was

    Hydro-Quebec generates, transmits and distributes electricity mainly produced by renewable energy sources. Its sole shareholder is the Quebec government. This annual report reviewed the operations of Hydro-Quebec, and provided data on energy sales, production and details of the utility's environmental programs. Information on Hydro-Quebec subsidiaries in 2005 was presented in the following separate sections: Hydro-Quebec Production; Hydro-Quebec TransEnergie; Hydro-Quebec Distribution; Hydro-Quebec Equipement; and the Societe d'energie de la Baie James. In 2005, Hydro-Quebec Distribution signed contracts for an initial block of 990 MW of wind power and issued a tender call for an additional 2000 MW of wind power. A generator balancing service was created and authorized by the Regie de l'energie. Hydro-Quebec customers have achieved energy savings of nearly 450 GWh in 2005. The commissioning of Toulnustouc generating station was achieved 5 months ahead of schedule. The 526 MW facility will generate 2.7 TWh annually. Work at the Chute-Allard and Rapide-des-Coeurs sites has continued, as well as construction at Mercier and Peribonka and Eastmain-1. Income from continuing operations came to $2.25 billion, a $124 million increase that was attributed to a rise in domestic sales and net short-term exports. The income was offset by higher pension expenses, depreciation and amortization, as well as by cost of supply on external markets and financial expenses. All other operating expenses were lower than in 2004. Capital spending for the transmission system reached its highest level since 1997, with $793 million invested, including $336 million to meet growth. Data on the company's financial performance, executive changes and reorganization were provided. Financial statements included a review and analysis of financial transactions, an auditor's report, as well as customary notes to the consolidated financial statement including balance sheets, assets, liabilities and

    The decay of the Laurentide ice sheet played an important role in the climate variability of the last deglaciation, notably through large discharges of meltwater from glacial lakes that disturbed the Atlantic meridional overturning oceanic circulation (AMOC). These former climate-forcing events are now under focus due to growing evidence showing that the present-day increase in freshwater releases from Greenland and other Arctic glaciers may potentially lead to a slowdown of the AMOC and cause important climate feedbacks. In northern Quebec and Labrador, the end of the deglaciation led to the formation of at least 10 important glacial lakes that drained into the nearby Labrador Sea where repeated meltwater discharges could have destabilized the ocean surface conditions in this key sector of the North Atlantic Ocean. Although the drainage of these ice-dammed lakes may form a good analogue for modern processes, the lack of direct constraints on the physiographic configuration and temporal evolution of these lakes limits our understanding of the timing and climate impact of these final meltwater pulses. Here we applied cosmogenic 10Be dating to raised boulder shorelines belonging to Lake Naskaupi, one of the largest glacial lakes in northern Quebec and Labrador. We reconstructed the lake extent and meltwater volume, as well as its lake-level history by systematic mapping of geomorphic features. We sampled a total of 16 boulders at 4 sites along the valley. In addition, we dated five boulders belonging to a large-scale outburst flood deposit recording the abrupt drainage of the lake. The distribution of the 21 ages shows a remarkable consistency, yielding a mean age of 7.8 ± 0.4 ka (1 outlier excluded). The ages from the shorelines are indistinguishable from those of the outburst flood deposit, suggesting that Lake Naskaupi existed for a relatively short time span. These new chronological data constrain the timing of the lake development and attendant drainage

    A revision of the genus Odocnemis of Turkey, the Caucasus and Iran is presented. Thirty species and four subspecies are distributed in this territory. The following 20 new species and subspecies are described: O. dichroa sp. n., O. allardi sp. n., O. merkli sp. n., O. seducta sp. n., O. aegaeica sp. n., O. euritopica sp. n., O. subtuberculigera sp. n., O. subtuberculigera thracica subsp. n., O. erseni sp. n., O. molecularica sp. n., O. shokhini sp. n., O. inornata sp. n., O. altimontana sp. n., O. amanosica sp. n., O. cordiformis sp. n., O. kakunini sp. n. O. evestigata sp. n., O. torosica sp. n., O. torosica subangulata subsp. n., Odocnemis hakkariensis sp. n. The name of the genus is feminine, therefore all species names are transformed from masculine to feminine. Almost all new taxa are described from Turkey; O. amanosica sp. n. is additionally recorded from Syria, O. allardi sp. n.-from Armenia, Azerbaijan (Nakhchivan) and Iran, O. kakunini sp. n. from Iran. New synonymies are established: Odocnemis anatolica (Pic, 1899) = Stenomax korbi Reitter 1902: 219, syn.n.; Odocnemis recticollis (Allard, 1877) = Stenomax kurdistanus Reitter, 1902: 221, syn.n.; Odocnemis punctata Allard, 1876 = Cylindronotus (Odocnemis) pseudoclarus Reitter, 1922, syn.n. The following lectotypes are designated: Helops (Odocnemis) anatolicus Pic, 1899, Helops (Stenomax) seriegranatus Seidlitz, 1896, Cylindronotus (Odocnemis) opertus Reitter, 1922, Stenomax recticollis Allard, 1876, Odocnemis punctata Allard, 1876, Helops (Odocnemis) protinus Reitter in Bodemeyer, 1900. Holotypes and paratypes of all other Turkish species of Odocnemis are studied. Two new combinations are established: Odocnemis gloriosa (Faldermann, 1837), comb. n. (from Nalassus Mulsant, 1854) and Odocnemis terminasianae (Nabozhenko, 2011), comb. n. (from Armenohelops Nabozhenko, 2002). Five species O. bosphoranus (Allard, 1876), O. amasiae (Seidlitz, 1896), O. scutellatus (Reitter, 1902), O. fundator (Reitter, 1908

    The stable carbon isotope (SCI) ratio of the sediment of Lake Memphremagog, Quebec is compared with that ot terrestrial sources and the phytoplankton to determine the relative proportion of allochthonous carbon incorporated into the sediments. Approximately 40-50% of the organic carbon in the main basins' pelagic sediment was terrestrial in origin, whereas up to 100% was terrestrial in littoral areas. The SCI method of determining the organic carbon source of sediments appears more reliable than the C/N method. A comparison of the SCI fractionation of the phytoplankton with laboratory cultures under different degrees of carbon limitation indicates that the phytoplankton of Lake Memphremagog are not carbon limited and fix carbon primarily by the C 3 pathway

    An environmental study was conducted on Chibougamau, aux Dores, Obatogamau, and Waconichi Lakes in northern Quebec in 2001. Those lakes are used by the Cree Indians for subsistence fishing and sport fishing by the rest of the Quebec population. Concentrations in heavy metals and polychlorinated biphenyls (PCB) were measured in sediments from Lakes Chibougamau and aux Dores. Heavy metals concentrations were also measured from two mining effluents and four waste samples originating from a mining waste location around the lakes. In addition, three fish species were sampled in those two lakes to evaluate the effect of mining activity on mercury levels in those species. The measurements were compared to those obtained from fish originating from Obatogamau and Waconichi Lakes. Finally, heavy metals, PCB, and dioxins and furans were measured in five fish species from the four lakes. The results of the analysis from the mining effluents revealed concentrations of the six metals included in directive 019 for the mining industry were lower than the authorized limits. However, a bio-essay performed in 2002 in the final effluent of the mining basin showed that the effluent from Copper Rand Mine presented toxicity and was not in agreement with the directive for this parameter. The sediments had low mercury concentrations. The highest concentration originated from the site near Henderson Mine I. None of the concentrations exceeded the limit and there are no negative effect expected on the fauna. Arsenic, cadmium, copper, nickel and zinc had high concentrations in sediments. The corresponding locations were near Copper Rand Mine, south of Principale Mine and at the foot of Principale Park. No PCB were detected in Chibougamau and aux Dores Lakes. Data does not indicate that the mining activity caused an increase in mercury levels in fish. Mercury levels in fish captured in 2001 in Chibougamau Lake were lower than those measured in 1999. 12 refs., 9 tabs., 12 figs.

  7. Using diatom assemblages and sulphur in sediments to uncover the effects of historical mining on Lake Arnoux (Quebec, Canada: A retrospective of economic benefits versus environmental debt

    Full Text Available Monitoring changes in environmental conditions is increasingly important as the Canadian economic infrastructure ramps up exploration and mining development in the more inaccessible northern regions of Canada. Governments are concurrently assessing effects from past mining activities and absorbing the economic cost to society with on-going remediation and monitoring initiatives. The abandoned Aldermac mine in northwestern Quebec, mined from 1932–1943, is an excellent case study for assessing the state of environmental and economic effects of past mining operations. A paleolimnological approach, using diatoms as environmental proxies, was used to evaluate the spatial and temporal impacts on aquatic receiving environments. Based on the inferences drawn from diatom assemblages in Lake Arnoux, prior to mining activity, lake water pH was similar to that of surrounding lakes (circumneutral to weakly acidic. After mining operations terminated, changes in pH and alkalinity in Lake Arnoux coincided with distinct increases in sediment sulphur content. Across a 30- to 40-year span (circa 1940 to 1970s a significant decline in phytoplankton flora coincided with lake acidification and increased clarity of the water column. This resulted in an increase in the benthic diatom population (>90%, replacing the planktonic diatoms. Observed shifts in environmental proxies are concurrent with one, and possibly two, reported tailings pond breaches at the abandoned mine site. Adverse effects of the abandoned Aldermac mine on nearby ecosystems, combined with pressure from local citizens and environmental groups, forced responsible accountability for site restoration led by the Quebec government. Based on the historical period of economic growth, the financial benefits of the Aldermac mine were significant and justify the current pay-it-backward costs for environmental remediation. However, it has now been documented that the pay-it-backward model is not sustainable in

    In 1962, a total of 46 companies shared Quebec's electricity production, involving no less than 9,710 megawatts of power. The 4 companies that controlled 85 per cent of this power were Hydro-Quebec, Aluminum Company of Canada (Alcan), Shawinigan Water and Power Company and the Gatineau Power Company. At the time, electricity rates also varied considerably throughout Quebec, being extremely high in regions far from Montreal, which hindered potential industrial development in those areas. This report discussed the privatization of Hydro-Quebec and how it could make Quebecers richer. The report discussed the early days of electricity in Quebec and outlined the reasons that led Quebec to nationalize the production and distribution of electricity and to entrust its management to Hydro-Quebec. A summary of the developments undertaken to enable Hydro-Quebec to substantially boost its exports to the United States following liberalization of the American market toward the end of the twentieth century was also provided. A comparison group of companies in the United States involved in the production, transmission and distribution of electricity was also presented in order to analyze Hydro-Quebec's performance from various standpoints. Other topics that were addressed in the report included operational efficiency; use of capital; the experience of the United Kingdom; the rise in electricity rates; a strategy for privatization; the public offering; and protecting Quebec electricity consumers. The role of the Quebec government and of Hydro-Quebec were also examined. Electricity exports and electricity and aluminum smelters were also assessed. The report noted that Hydro-Quebec's annual profit would shrink from $2,882 million to $709 million if it had to pay the market price for the electricity it obtains from Churchill Falls. 23 tabs., 1 fig., 2 appendices

    Power generation in Canada is a provincial responsibility. Since Quebec does not possess petroleum, natural gas or coal deposits, the Quebec government decided, in the 1970s, to develop hydroelectric resources in the northern regions of the province. This paper presents a brief historical overview of the hydroelectric development of the La Grande River project, also referred to as the James Bay project. Located approximately 1000 kilometres north of Montreal, the La Grande project lies in a humid continental climate with an average winter temperature of - 23 Celsius and an average summer temperature of 14 Celsius. The construction of the dam was not preceded by an environmental impact assessment, but environmental data was collected for the first time before construction began. It was an opportunity for all environmental sciences to develop inventory methodologies and analysis techniques specific to northern regions applicable to hydroelectric development. This project also required the signing of the James Bay and Northern Quebec Agreement by the governments of Canada and Quebec, Hydro-Quebec, and the Crees and Inuit of Quebec. The Agreement covers an area of 1 million square kilometres. As a result, Hydro-Quebec has become, over the past 30 years, a leader in environmental assessments and studies in the province. In northern Quebec, a hydroelectric reservoir constitutes an ecosystem whose biological productivity is comparable to a natural lake or ecosystem of equal area. During the first 5 years after flooding, reservoirs possess water quality slightly below that of a natural lake, but still favorable to biological development. The flooding of areas and the subsequent organic degradation promote mercury methylation and its accumulation in the food chain. The emissions of greenhouse gases by northern reservoirs are minimal compared to tropical reservoirs. The fauna in northern Quebec suffered habitat loss, but none became endangered.

    It has been demonstrated that intensive fishing, i.e., removing more than 25% of the fish biomass, can reduce mercury levels in predator fish in a lake. We test here the hypothesis that, by removing an important part of the fish biomass from a lake, a significant amount of methylmercury can be eliminated, therefore reducing the mercury available to the remaining biota, at least in the short term. A mass burden approach is used to evaluate the partitioning of total mercury and methylmercury in natural lake ecosystems. Three small natural lakes from the James Bay territory, in northern Quebec, Canada, were selected for intensive fishing. Mercury (Hg) and methylmercury (MeHg) concentrations were evaluated for sediments, water column (dissolved fraction and suspended particulate matter), plankton, aquatic invertebrates, and fish. Biomasses were determined for fish, plankton, and aquatic invertebrates. Two case scenarios are presented using different mercury contributions from the sediment component (1 cm depth, and no sediment). Our results for the scenario including the sediment contribution show that lake sediments represent over 98% of the total mercury while the biotic components represent less than 0.1% of the same burden. For methylmercury, fish account for up to 5% of the burden, while sediments make up 84.6% to 93.1%. If we put aside the sediment contribution, the methylmercury in fish partitioning can represent up to 48%. As for invertebrates, they can account for up to 48% of the total MeHg burden. We do not observe any change in the partitionings or the quantities of Hg and MeHg before and after fishing in either of the two case scenarios even when we do not take into account dynamics of the ecosystems. This will be all the more the case when the dynamics of the system are included in the analyses. Therefore, biological parameters such as growth rates or fish diet must be considered.

    Burnham, N.

    1998-01-01

    The controversy over Hydro-Quebec's plan to divert eight more rivers to generate more electricity for export to the United States was discussed. Hydro-Quebec would like to proceed with the projects in order to capitalize on the recently deregulated American energy market. Hydro-Quebec currently produces more electricity than it requires to service domestic demand. Therefore, the majority of the newly generated power will likely be exported. Hydro-Quebec's strategic plan states that it intends to undertake diversion projects in the James Bay region. Critics of the plan argue that developing all of the province's remaining hydroelectric potential would jeopardize the environment and the aboriginal communities of the region. On the other side, Hydro-Quebec maintains that hydroelectric development has not upset the ecological balance in northern Quebec. Several secondary impacts of hydroelectric development were also described. Quebec's newly created Energy Board (Regie de l'energie) will encourage discussions between consumers, industry and environmentalists to debate Quebec's energy issues, as well as oversee and regulate retail prices, exports, investments and investment priorities

A brief review of charges of less than competent management, low profitability and the corporation's recent administrative restructuring was presented. The general thrust of the argument was that Hydro-Quebec plays a crucial role in the economic development of Quebec, it can be made to be more profitable and that for the good of Quebec it should continue as a public corporation under the control of the provincial government

    The fluctuations of mercury levels (Hg) in fish consumed by sport fishers in North-Eastern America depend upon a plethora of interrelated biological and abiological factors. To identify the dominant factors ultimately controlling fish Hg concentrations, we compiled mercury levels (Hg) during the 1976-2010 period in 90 large natural lakes in Quebec (Canada) for two major game species: northern pike (Esox lucius) and walleye (Sander vitreus). Our statistical analysis included 28 geographic information system variables and 15 climatic variables, including sulfate deposition. Higher winter temperatures explained 36% of the variability in higher walleye growth rates, in turn accounting for 54% of the variability in lower Hg concentrations. For northern pike, the dominance of a flat topography in the watershed explained 31% of the variability in lower Hg concentrations. Higher mean annual temperatures explained 27% of the variability in higher pike Hg concentrations. Pelagic versus littoral preferred habitats for walleye and pike respectively could explain the contrasted effect of temperature between the two species. Heavy logging could only explain 2% of the increase in walleye Hg concentrations. The influence of mining on fish Hg concentrations appeared to be masked by climatic effects.

    In mid-1995 the Parti Quebecois, then in opposition, claimed evidence of influence peddling, international drug money laundering, kickbacks and fraud in Quebec`s independent power program. It also claimed evidence of irregularities at Hydro-Quebec in its procedures for approving hydropower projects. The Liberal Quebec government of the day ordered a public inquiry, led by Quebec superior court judge Francois Doyon. He submitted the Commission`s final report in April 1997. The report exonerated Hydro-Quebec and the province`s independent power industry of any criminal wrong doing regarding their respect for legal and regulatory directives and the `ethical norms and practices` of sound business management. In its 600-plus page report, the Doyon Commission found that while there was a certain lack of administrative rigor which allowed certain Hydro-Quebec executives to put themselves in questionable conflict-of-interest situations, their actions were not illegal. The current Parti Quebecois Government accepted the report and its recommendation concerning tightening conflict-of-interest guidelines. The current Liberal opposition in the National Assembly charged that the conclusions of the Commission were a foregone conclusion since the demand for the inquiry was politically motivated right from the beginning.

    Electricity exports from Hydro-Quebec to utilities in the USA significantly affects the economy and environment of Quebec. These exports may be arranged under interconnection agreements to sell excess capacity and production during off-peak periods or under firm sales contracts. Hydro-Quebec exports could also replace power plants that would otherwise be needed in the USA. The economic environment for Hydro-Quebec exports to the USA is reviewed along with the regulatory environment applicable to international trade (General Agreement on Tariffs and Trade, Canada-USA Free Trade Agreement, North American Free Trade Agreement), Quebec (Canadian federal and provincial law), and the USA (federal and state law). A jurisdictional analysis of power export contracts is then presented, citing examples of contracts already signed by Hydro-Quebec with utilities in New York and New England. Contract law and contract provisions are discussed, including common clauses and particular clauses. Suggestions are made for new clauses that would improve the electricity trade. 215 refs., 13 figs., 3 tabs

    Hydro-Quebec's telecommunication system, the largest private telecommunications network in Canada, was discussed. The network was set up to assure safety and efficiency of the power plants and energy transmission and distribution lines. By the year 2000 Hydro-Quebec will need electronic links with all its industrial, commercial and residential customers in order to guarantee competitive service and full customer satisfaction. Investments of about one half billion dollars have been earmarked to boost the capacity of their telecommunications grid and meet steadily growing needs. As a result of the very difficult negotiations to resolve the native land claims issue, Hydro-Quebec was forced to adapt a strict and far-reaching environmental policy, which is now beginning to pay off not only in environmental terms, but also in terms of goodwill among actual and prospective customers. As a result of these huge infrastructure projects Hydro Quebec will be in a position to guarantee people access to energy at a price that is among the lowest in the world. Although demand growth could slow, demand itself will not wane. As part of this overall strategy, Hydro-Quebec plans to defer large-scale projects, instead, for the foreseeable future it will concentrate on smaller power plants, some of which could be built on rivers that have already been tamed

    International Nuclear Information System (INIS)

    2001-01-01

    A corporate profile of Hydro-Quebec was presented and the strategy that the utility will adopt for the 2002-2006 period was summarized. The utility plans to maintain its service quality and sustain environmental quality while developing a world class enterprise. Quebec has adopted a heritage pool giving Quebec consumers access to a maximum of 165 TWh of electricity per year at an average commodity rate of 2.79 cents per kilowatt-hour, the lowest rate for such a large amount of energy in North America. Above that volume, supply for the Quebec market will be ensured through competitive bidding, leading to the signing of supply contracts based on market price. Hydro-Quebec's strategy reflects the business opportunities open to Hydro-Quebec given its traditional activities in the province, the restructuring of North American energy markets, and the emergence of Quebec as a major energy hub. The business opportunities come from the fact that demand for electricity in Quebec is growing and from the opening of markets close to Quebec. Investment outlook in hydroelectric generation and transmission also appears to be profitable. It is likely that investment will be needed to build infrastructure. Hydro-Quebec is also working with its qualified workforce to develop a world-class international activity base. tabs., figs

    Hydro-Quebec produces, transmits and distributes electricity through the use of renewable energy sources, particularly hydroelectricity. It also conducts research in energy related fields. This document listed the strategic plan for Hydro-Quebec's 4 main divisions: Hydro-Quebec Production, Hydro-Quebec TransEnergie, Hydro-Quebec Distribution and Hydro-Quebec Energy Society of Bay James. The 2006 to 2010 strategic plan continues to focus on 3 main priorities: energy efficiency; complementary development of hydroelectricity and wind power; and, technological innovation. Hydro-Quebec's objectives also include strengthening the security of Quebec's energy supply and making use of energy as a lever for economic development. The plan for Hydro-Quebec Production calls for accelerating the development of major hydroelectric projects and promoting other renewable forms of energy such as wind power and ensuring the efficiency and reliability of the generating fleet. The utility's objective is to reach 4.7 TWh in energy savings by 2010 and to work toward a target of 8 TWh by 2015. The plan also involves a portfolio of hydroelectric projects totaling 5,400 MW. The plan includes complementary development and integration of 4,000 MW of windpower by 2015. The plan for Hydro-Quebec TransEnergie calls for system reliability and becoming a world benchmark for quality and reliability in wind power integration and deployment of new technologies to enhance performance. The plan for Hydro-Quebec Distribution calls for more efficient use of electricity, increase customer satisfaction and meet electricity needs through the use of renewable energy sources. The utility has made a commitment for 2006 to 2010 to a net income of $2.5 billion per year for a total of $12.5 billion, and a capital investment of 19.4 billion. This paper outlined the contribution of each division to net income and listed the economic benefits for the 2006 to 2010 period. In 2006, the Quebec Energy Board authorized

  1. New Quebec renewable energy organization

    1998-04-01

    The recent formation of the Quebec Association for the Production of Renewable Energy (l`Association quebecoise de la production d`energie renouvelable - AQPER) was announced. The Association is becoming the centre of the Quebec private electricity generation industry. By communicating the industry`s message to the public the organization gives much needed visibility to renewable resources, new forms of energy and sustainable development. The new group is an outgrowth of the former Quebec Association of Private Hydroelectricity Producers. In its new reincarnation, the organization represents all forms of renewables, small and medium hydro, wind, solar, forest and agricultural biomass and urban waste. With deregulation of the electricity market, specifically the creation of the Regie de l`energie` in Quebec, the wider role is a welcome boost for renewable energy development in the province. In one of its first actions the AQPER recommended that all hydroelectric sites up to 50 MW be reserved for development exclusively by the private sector, in conformity with the Quebec energy policy announced in 1996.

    Full Text Available This communiqué provides a summary of the production- and consumption-based greenhouse gas emissions accounts for Quebec, as well as their associated trade flows. It is part of a series of communiqués profiling the Canadian provinces and territories.1 In simplest terms, a production-based emissions account measures the quantity of greenhouse gas emissions produced in Quebec. In contrast, a consumption-based emissions account measures the quantity of greenhouse gas emissions generated during the production process for final goods and services that are consumed in Quebec through household purchases, investment by firms and government spending. Trade flows refer to the movement of emissions that are produced in Quebec but which support consumption in a different province, territory or country (and vice versa. For example, emissions associated with the production of a Quebec manufactured good that is exported to Ontario for sale are recorded as a trade flow from Quebec to Ontario. Moving in the opposite direction, emissions associated with the production of motor gasoline in New Brunswick that is exported to Quebec for sale are recorded as a trade flow from New Brunswick to Quebec. For further details on these results in a national context, the methodology for generating them and their policy implications, please see the companion papers to this communiqué series: (1 Fellows and Dobson (2017; and (2 Dobson and Fellows (2017.

    2010-01-01

    The province of Quebec aims to have 4000 MW of wind energy interconnected to the electricity grid by 2015, and hopes to have 12,000 MW by 2025. This PowerPoint presentation explored some of the technical issues that may challenge the province's wind energy goals. The last decade has seen Quebec dominated by a tight supply and demand electricity market and a wholesale market dominated by short term contracts. Quebec aims to create surplus energy for exportation as well as to have 10 percent of the Hydro-Quebec power system supplied by wind resources. Electricity demand is expected to increase over the next decade. Quebec's wind resource development represents an alternative strategy to the development of hydro-electric resources. Strategic planning is needed to develop Quebec's integration potential. However, high standards are needed to ensure the reliability of the province's large electricity system, which is vulnerable to extreme weather events and technical failures. Various power contracts and agreements are being explored by Hydro-Quebec in order to supply power reliably during peak periods. Details of studies conducted to assess Quebec's wind power potential in relation to the electricity system were discussed, and the impact of wind power on the system was evaluated. refs., tabs., figs.

    Architecture at Hydro-Quebec is concerned not only with combining function and aesthetics in designing buildings and other structures for an electrical utility, but also to satisfy technical and administrative needs and to help solve contemporary problems such as the rational use of energy. Examples are presented of Hydro-Quebec's architectural accomplishments in the design of hydroelectric power stations and their surrounding landscapes, thermal power stations, transmission substations, research and testing facilities, and administrative buildings. It is shown how some buildings are designed to adapt to local environments and to conserve energy. The utility's policy of conserving installations of historic value, such as certain pre-1930 power stations, is illustrated, and aspects of its general architectural policy are outlined. 20 figs.

  5. Quebec-Vermont dispute may upset export plans

    International Nuclear Information System (INIS)

    McArthur, D.; Salaff, S.

    1999-01-01

    A major trade dispute between Hydro-Quebec and a group of Vermont utilities arising out of Hydro-Quebec's inability to live up to its contractual obligations to supply electricity to the Vermont group during the January 1998 ice storm is discussed. The Vermont Group initiated legal action against Hydro-Quebec, claiming refund of $ 27 million and termination of the contract . The Vermont utilities claim that the storm has revealed the weakness of the design, construction, operation and maintenance of Hydro-Quebec's transmission system. In its defence, Hydro-Quebec asserts that its transmission system meets industry standards, considers the storm 'an act of God' and invoked 'force majeure' when it ceased supplying power to Vermont last year. Hydro-Quebec further alleges that the Vermont utilities are using the storm as a pretext to end or renegotiate the contract. Hydro-Quebec asked the Canadian government to intervene under NAFTA, alleging trade harassment by the Vermont Public Service Commission (VPSC) when it restricted Vermont utility rate increases. In a countermove, Vermont U.S. Senator Jim Jeffords threatened future power exports by Canada to the U.S. for pursuing a NAFTA complaint, thereby hoping to influence negotiations between Hydro-Quebec and the Vermont utilities. The latest development in this dispute, which potentially threatens the development of 4000 MW of new hydroelectric development at Churchill Falls, Labrador, is that the dispute may now be settled with an auctioning of the contract. If the U.S. were to block the import of new power from Churchill Falls, the project could be jeopardized. However, the contract auction may well avoid such major international ramifications and a full-fledged trade war between Canada and the United States

    Full Text Available The aim of this research was to conduct a thorough review on the literature of tuberculosis in Canada and the Province of Quebec. To achieve this aim, an exhaustive literature review of tuberculosis in the Province of Quebec was undertaken. Data was collected with the goal of creating an epidemiological and public health evidence base to forecast the spread of tuberculosis. A keyword search strategy was used to find relevant articles from the peer-reviewed literature using the electronic search engine PubMed and a search of other relevant federal and provincial government databases. Twenty-nine peer-reviewed publications and twenty government reports containing information about the incidence or prevalence of tuberculosis in the Province of Quebec were included in the analysis. An analysis of the data revealed that while tuberculosis rates have been decreasing in both Canada and Quebec with an overall incidence below 3 per 100,000 of population in 2007, among immigrants and the Inuit communities in Quebec, the incidence and prevalence of the disease still remains high and reached 18 per 100,000 and 100 per 100,000, respectively in 2007. In general, while tuberculosis does not pose a significant burden to the general population, it does continue to affect certain sub-groups disproportionately, including select immigrants and Inuit communities in Quebec. Efforts to ensure that cost-effective healthcare interventions are delivered in a timely fashion should be pursued to reduce the associated morbidity and mortality of tuberculosis in the Province of Quebec.

    1992-01-01

    The activities of Hydro-Quebec are analyzed from the standpoint of their contribution to economic development and their support of regional development. The structuring effects of Hydro-Quebec's electricity supply activities are described, specifically the utility's role as an employer and an important agent of economic development by virtue of its purchasing power. The role played by research and development activities in the technological development of Quebec is discussed along with the contribution of those activities to new industrial developments. Finally, the impacts of electricity use on industrial development are considered. An analysis is presented of Hydro-Quebec's marketing activities and the options they afford. These marketing activities are aimed mainly at supporting economic development. The availability of reasonably priced electricity enhances the competitiveness of all industrial sectors, especially those for which electricity is a factor in siting. Furthermore, Hydro-Quebec can use its marketing activities to reinforce this comparative advantage. Hydro-Quebec can also support regional development by decentralizing operations, standardizing rates, and extending its marketing activities to the regions. 2 tabs

    In March 2000 the Association de l'industrie electrique du Quebec hired the strategic marketing firm of Leger and Leger to conduct a survey of the Quebec population with the following three objectives in mind: (1) to evaluate the general opinion of the Quebec population regarding the development of new hydroelectric projects, (2) to determine the public opinion regarding the exportation of electricity, and (3) to evaluate the public opinion regarding certain hydroelectric projects that were already underway. 1000 adults were polled. It was determined that a large majority (84.2 per cent) of Quebecers are in favour of new hydroelectric development in the province as long as certain conditions are respected, such as maintaining jobs and not incurring an increase in the price of electricity. It was also determined that Quebecers are under the impression that the province exports much more electricity than it actually does. 66 per cent of the population believe that the province is exporting more than 20 per cent of its electric power production outside of the province. In reality, the province exports on average 10 per cent of its production. 71.5 per cent of Quebecers agree to new projects of exportation as long as the projects do not decrease the capacity for the province to fulfill its own power needs. In terms of environmental perceptions, hydroelectric power is considered to be the second least polluting source of energy both from an air pollution and visual pollution point of view. 72.6 per cent of the people said that hydro produces less greenhouse gases than electricity produced by natural gas or coal. Also 83.4 per cent recognized that hydro is a renewable resource. In general, the people surveyed were also in agreement with the development of new transmission lines. 86.8 per cent agreed with the construction of a transmission line between the Laurentians and the Outaouais. The polls are accurate to 3.1 per cent precision 19 times out of 20. tabs., figs

    International Nuclear Information System (INIS)

    1999-01-01

    Hydro-Quebec is a publicly owned company with a single shareholder, the Quebec government. In 1998, the utility had over 31,400 MW in installed capacity, ranking it among North America's largest distributors of electrical energy. This report provides a review of progress and financial highlights including revenue, expenditure, financial expenses, net income, total assets, long term debt, shareholder's equity and the overall financial position of the utility. In 1998 sales totaled 161.4 TWh, with Quebec markets accounting for more than 88 percent and sales, outside Quebec accounting for 11.5 per cent. Three factors related to weather impacted the utility in 1998. The first was mild weather which brought down domestic and agricultural power consumption by 3 TWh compared with the average recorded in the past half-century. The second was low precipitation which caused Hydro-Quebec to turn to means other than hydroelectric generation to supply power to Quebec customers. These included start-up generation of the Tracy thermal generating station, reduction of sales on short-term markets outside Quebec, and electricity purchases on external markets. The third factor was the ice storm of January 1998, which caused significant damage to part of Hydro-Quebec's transmission and distribution systems. Throughout the year, Hydro-Quebec worked in reinforcing its power lines to prevent repetition of the devastation that occurred during the ice storm. In spite of the events of January 1998, the Utility remains committed to the growth and profitability orientations laid out in its Strategic Plan for 1998-2002. Significant progress was made in consolidating the Utility's position in international markets. Productive partnerships have been established with the Quebec Federation of Labour Solidarity Fund, and with Gaz de France. A network of international partners in a score of countries also has been developed. Hydro-Quebec has completed most of its preparations for Year 2000 readiness

    Canada's second largest oil refinery is operated by Ultramar Ltd. in Levis, Quebec. The refinery, which supplies 45 per cent of all Quebec's petroleum, distributes its products to Quebec, Ontario and the Maritime provinces. The refinery currently produces 215,000 barrels per day. Ultramar is a division of Valero, an American firm which has a total refining capacity of 2.4 million barrels per day. A summary of the company's petroleum energy distribution, consumption, and reserves was presented and compared with the national and global position. It was noted that world demand for petroleum products increases yearly by 1 to 1.5 per cent while the demand for automobile fuel in North America increases by 2.5 to 3.5 per cent. In the last 10 years, world demand has increased by more than 22 per cent but refining capacity has only increased by 12 per cent. The average profitability of the refining industry from 1992 to 2002 was approximately 5.5 per cent, which limited investments in new refinery installations. Much of the industry's profits have been utilized to modify installations in order to reduce the sulphur content in gasoline and diesel fuels. Furthermore, the obtention of permits to construct new refining installations has become a major obstacle and the ratification of the Kyoto Protocol may signify a 30 per cent reduction in automotive fuel demand. Given this, there is currently some hesitation and uncertainty by the refining industry to proceed with new major installations. tabs., figs

    2006-05-01

    This analysis examined the current situation of wind power development in the province of Quebec and presented a qualitative assessment of the economic repercussions in terms of employment, investments and environmental and social impacts. The development of the wind power industry in Quebec gained momentum in 2003 when the provincial government expressed support for fast growth of wind power. In response, Hydro-Quebec launched an invitation to interested stakeholders to tender for 1000 MW of wind power projects to be installed between 2006 and 2012. The invitation was a great success, with more than 4000 MW of projects filed. The average price of the selected offers was 6.5 cents per kWh for 990 MW in 8 projects. The economic repercussions related to construction of wind farms in the Gaspe was discussed along with indirect and induced economic repercussions for suppliers and subcontractors in the entire province. It was noted that Quebec is already a leader in the field of electricity and wind energy consultation. Stimulated by these successes, the government of Quebec recently raised its target for wind power development to 2,500 MW. Therefore, taking into account the wind developments already supported by Hydro-Quebec, the installed wind capacity in Quebec is expected to reach more than 4000 MW by 2015, with an investment by the wind power industry of more than 5.8 billion dollars. The wind power industry is expected to generate 45,000 direct or indirect jobs for more than a 20 year period. Presently, the government of Quebec supports the establishment of a local wind market to promote free competition, energy diversity, and coexistence of key players. As its international support mechanism, Quebec chose to integrate regional economic development criteria with the price of electricity. In the long term, the wind industry could constitute a key element in Quebec's sustainable energy development plan. 9 refs., 1 tab

    The history of the electric utility Hydro-Quebec is reviewed from its creation in 1944 as the Hydroelectric Commission of Quebec. The utility inherited an installed capacity of 696 MW and it first went about standardizing electricity supply conditions and establishing equal rates in the Montreal area. It began major construction projects in the mid-1950s with the Bersimis and Carillon hydroelectric plants. By 1962, installed capacity reached 3,657 MW. In 1963, Hydro-Quebec bought 10 private electricity distribution companies, 45 cooperatives, and a series of private or municipal systems. In 1965, the utility commissioned the world's first 735-kV transmission line. In 1967, Hydro-Quebec opened its research institute, and another laboratory specializing in electrotechnologies was opened in 1987. The 1970s were noted for the James Bay hydroelectric projects, the development of which was eventually governed by the landmark James Bay and Northern Quebec Agreement of 1975. Electricity exports greatly expanded in the 1970s and early 1980s as larger hydroelectric projects came on stream. Challenges of the 1990s include service quality, environmental issues, energy efficiency, and conservation. Hydro-Quebec's Energy Efficiency Project has a target of annual savings of 9.3 TWh by the year 2000. Energy efficiency and power system upgrading are priorities for serving future customer needs. Hydro-Quebec continues to promote hydroelectric power as the cheapest, most environmentally benign form of energy and future generating stations in progress include phase II of the LaGrande complex (to be completed 1996). 2 figs

    2006-05-01

    A summary of Quebec's energy strategy was presented. The principal objective of the strategy is to strengthen energy supply security, while making better use of energy as a lever for economic development. The strategy prioritized the development of hydro-electricity, wind energy potential, hydrocarbon reserves, and the diversification of natural gas supplies. Greater communication between government agencies, local communities and First Nations groups was recommended. Energy efficiency measures were outlined. The strategy emphasized Quebec's future role as a leader in the sustainable development field. It was stated that electricity rates will be set at a level that promotes the interests of Quebec while ensuring proper management of resources, improved price signals and customer protection. Orientations and priority actions to achieve the strategy's objectives include: (1) resumption and acceleration of developing hydroelectric potential through a variety of new projects totalling 4500 MW within the next 5 years, (2) the exploitation of Quebec's estimated 4000 MW of potential wind power, (3) increasing the overall energy efficiency target by a factor of 8 compared to current targets to allow for $2.5 billion in annual savings for consumers, (4) supporting and promoting innovation financed through part of the levy garnered on all forms of energy with a particular priority on biomass energy development, (5) developing the oil and gas resources in the Gulf of St. Lawrence and estuary, and (6) responding more effectively to the predicament of low-income households.

    Quebec depends on fossil fuels which come from outside Quebec for its energy supply. It has available significant hydraulic resources, but they should be totally harnessed within 30 years; therefore, other energy sources must be found. The nuclear route can provide a way for Quebec to meet its future needs. From the technical, economic, security of supply, and side benefit points of view, the recourse to nuclear seems reasonable and even advantageous. From a socio-political point of view, however, the risks inherent in the use of nuclear energy are extremely important and need well-informed public discussion. In the meantime Quebec ought to stress the other sources that are available (hydroelectricity) or likely to be available (Canadian gas) while these sources can still be used at a reasonable price [fr

    With the ever increasing demand for electricity, it is estimated that the world`s electrical generating capacity will grow by about 1,000,000 MW over the next eight years. This represents a 40 per cent increase over today`s capacity. Hydro-Quebec is determined to stake its place in international markets and to maximize the profits from the strong expertise gained during the construction of Quebec`s major electric facilities. The venture into international markets is primarily a commercial strategy. To that effect, Hydro-Quebec plans to invest up to $300 million in international projects around the world so that after five years it can have major interests and assets totaling $12 billion or more. China, North Africa and the Middle East are some of the market that Hydro-Quebec wishes to enter in the years ahead. The Eastern European and Southeast Asian markets are also worthy of interest. It was pointed out that Hydro-Quebec is not the only large electric utility turning to world market to pursue its growth. French, Spanish and American companies are also presently investing billions of dollars in the world market.

    1997-01-01

    Hydro-Quebec Energy Services US (HQUS), the marketing arm of Hydro-Quebec, amended its application for a power marketing licence with the Federal Energy Regulatory Commission (FERC), by offering to open up five per cent of the wholesale Quebec electricity market to competition. The Corporation hopes that its revised application will satisfy FERC to grant HQUS a power marketer licence, with the right to sell electricity in the US at market-based rates. Hydro-Quebec insiders believe that in addition to opening up the market to competition, thereby equalizing market conditions on both sides of the border, the Corporation's chances of receiving the licence also have been improved by the creation of the provincial energy board (Regie de l'energie) which in future will regulate electricity and gas transmission through Quebec, and establish transmission tariffs. FERC ruling is expected within 60 days of the March 7, 1997 amended application

  10. Analysis of the Hydro-Quebec development plan 1992-2010

    1994-01-01

    In November 1992, the Quebec provincial utility Hydro-Quebec presented its development plan for the 1992-2010 period and shortly thereafter introduced its 1993-1995 energy efficiency commitments. The plan is analyzed using a model that incorporates the main institutional features of electricity price setting. Two scenarios are constructed. The first incorporates Hydro-Quebec's electricity demand forecast and the second allows electricity demand to respond to its price. A comparative analysis shows that electricity demand in the province should increase faster than forecast by Hydro-Quebec until 2010. In fact, demand could exceed the predicted level by ca 16 TWh, or 8.6%. This larger increase is due to a fall in the real price of electricity, itself caused by a government imposed fall in the real unit cost of the utility's operation. This last constraint is the real challenge faced by Hydro-Quebec. 12 refs., 7 tabs

  11. Quebec's electricity exports

    1992-01-01

    In 1987 Hydro-Quebec exported over 16 TWh to New England and New York and it plans to export 3,500 MW of firm power, not interruptible, by the early 2000s. It estimates that the northeast US market has an additional potential of 9,000 MW. The export market has become more difficult than anticipated. The federal/state regulatory framework for electricity generation was changing - it encouraged small scale generation, cogeneration and conservation which decreased demand. Demand for power imports has also been influenced by pricing judgements and avoided costs. Environmental concerns and Native protest have become increasingly important factors affecting future export sales and hence the proposed James Bay developments. Regulatory changes affecting supply and pricing, concerns about continental impacts, about further development of electrical sources together with Native requirements will further complicate the Quebec-US electricity trade.

    An overview is presented of the activities of Hydro-Quebec for the year ended December 31, 1993, as well as its financial status. Export sales of electricity to other Canadian provinces and the USA are reported. Research programs and demonstration projects are described, as well as the utility's international activities. Environmental and economic considerations for the province are presented. Financial data includes total sales, sales by sector, export sales, and rate changes. A financial statement is included. In 1993, total sales volume was 152.1 TWh, or 7.5 TWh more than in 1992, for a total sales revenue of $7,004 million, an increase of 3.5% over 1992. Sales in Quebec increased 5 TWh, with nearly all of this increase coming from the industrial sector. Exports outside of Quebec totalled 15 TWh, or 20% more than in 1992. The largest increase in exports was in the form of short-term sales to the USA. Expenditures in 1993 were $3,761 million, only slightly more than in 1992. Facilities commissioned in 1993 included the Brisay power plant, two of six units at the Laforge-1 plant, and the north portion of the 12th transmission line from the LaGrande complex. Total installed capacity of the Hydro-Quebec system reached 29,131 MW, and total power produced was 131.6 TWh. Total length of transmission and distribution lines in 1993 reached 29,869 km and 100,908 km respectively. 9 figs., 17 tabs

    As a net energy importer, issues of energy security are becoming increasingly important in Quebec. Since Quebec's energy policy is largely based on the development of hydropower, its energy development has already been consistent with sustainable development. Industry remains the largest energy consumer in Quebec, followed by the transportation sector, and the residential, commercial and agricultural sectors. Total energy consumption in the province is expected to increase by 1.2 per cent annually between 2001-2016. Although competitive electricity prices in Quebec have contributed to strengthening the provincial economy, it has been argued that the low price of electricity does not promote energy efficiency nor the development of alternative energy sources. Quebec imports all of its crude oil and natural gas. Energy production in the province is currently confined to electricity generation and refining of petroleum products at 3 main refineries. In 2005, the installed electrical capacity was 92.2 per cent hydropower, 5.3 per cent thermal power, 1.5 per cent nuclear power, and 0.9 per cent wind power. The vast majority of this installed capacity (78 per cent) is owned by Hydro-Quebec. Wind capacity is expected to reach 3,500 MW by 2017, representing about 8 per cent of Quebec's total electrical capacity. Guidelines have been identified in Quebec's energy strategy for 2006-2015 to promote energy efficiency and innovation of new energy technologies covering all markets and all forms of energy, including geothermal energy, solar energy and ethanol produced from forest residues, agricultural wastes and municipal wastes. The government's overall goal is to generate both energy savings and a reduction in annual greenhouse gas emissions.

    The Centre d'Expertise Hydrique du Quebec (CEHQ) manages dams used for flood control, water supply, recreational activities and hydroelectricity in the province of Quebec. This paper addressed the issue of global warming and the impact on the hydrological regime within the next decades. The changes in the hydrological regime may pose a risk of losing the equilibrium between various objectives, identifiable through water management plans. The CEHQ conducted a pilot study for the Saint-Francois and Aylmer reservoirs in order to formulate a method for evaluating the adaptability of currently used management plans to climate change. The project was based on potential climate change scenarios as well as on deterministic and distributed hydrological models. Daily time steps were used to evaluate the hydrological impacts of climate change. The newly developed model makes it possible to evaluate and compare the occurrences where stream flows and water levels exceed critical values. The effectiveness of the management plans in both current and climate change scenarios was evaluated. Preliminary results suggest a possible increase in flood risk and fewer low water level occurrences. It was concluded that climate change will influence the trade-off between different management objectives of the reservoirs. Although adaptation measures may be feasible, it was determined that there is no unique solution to all climate change scenarios. 27 refs., 7 tabs., 12 figs

    Architecture at Hydro-Quebec is concerned not only with combining function and aesthetics in designing buildings and other structures for an electrical utility, but also to satisfy technical and administrative needs and to help solve contemporary problems such as the rational use of energy. Examples are presented of Hydro-Quebec's architectural accomplishments in the design of hydroelectric power stations and their surrounding landscapes, thermal power stations, transmission substations, research and testing facilities, and administrative buildings. It is shown how some buildings are designed to adapt to local environments and to conserve energy. The utility's policy of conserving installations of historic value, such as certain pre-1930 power stations, is illustrated, and aspects of its general architectural policy are outlined. 20 figs.

    2007-01-01

    Throughout the world, electricity market liberalization has taken place or is currently underway. However, in Canada, the province of Quebec has undertaken limited restructuring measures. Considerable debate as to the potential for further market restructuring has been ongoing. This article discussed the potential for future electricity market restructuring in Quebec where competition in electricity supply has resulted in 3 categories of supply distribution, including a block of energy and power known as the heritage pool. This article considered the political economy of the abolishment if the heritage pool requirement, which caps wholesale prices. The article presented a statistical overview of Quebec's electricity market and discussed the regulatory environment. It also identified the potential for market restructuring and the establishment of a competitive wholesale market. It was concluded that Quebecers could significantly benefit from any restructuring initiative that involved the elimination of the Heritage Pool requirement if the extra rents were properly redistributed and that production sector restructuring would be difficult. 37 refs., 3 tabs., 4 figs

  17. Proposed Hydro-Quebec development plan, 1993: Proposal

    International Nuclear Information System (INIS)

    1992-01-01

    The Quebec government now requires Hydro-Quebec to submit a development plan every three years instead of annually, in order to permit more in-depth studies and a broader consultation with interested parties. In the first of such three-year plans, a series of plan proposals is presented which was developed after a year of consultation with various groups on four fundamental matters: energy efficiency, means of generation, electro-intensive industries, and electricity exports. Options for meeting future demand at Hydro-Quebec are assessed, including the construction of new generation and transmission facilities, rehabilitation of existing facilities, improving electrical energy efficiency, and conservation strategies. These options are considered while applying the principle of sustainable development that respects the environment. Hydroelectricity will continue to be emphasized as the main source of generation since hydroelectric facilities offer distinct advantages in terms of costs, environmental impacts, and economic spinoffs. The proposed plan also presents objectives and strategies for improving the quality of service and internal operations. Financial forecasts for Hydro-Quebec are proposed which take into account the forecast changes in the utility's cost and revenue factors and its self-financing requirements. 5 figs., 15 tabs

    In 2001 the diversified markets in Quebec totaled 12.6 billion $CAN. This included electricity sales at 62.3 per cent, sales of natural gas at 8.8 per cent, and sales of electricity to the United States at 24.8 per cent. The paper included several view graphs depicting the average price of electricity by province and state, as well as regional transmission organizations. Tables outlining the restructuring and regulatory processes in Quebec from the fall of 1996 to 2000 were included along with an outline of the strategic plan and implications of Bill 116. A graph depicting Hydro-Quebec distribution and call for tenders for an additional 4100 MW from 2000 to 2016 was presented along with a list of accepted bids with the company name, location and type of power generation (hydraulic with reservoir, run-of-river, cogeneration-natural gas, or biomass). Other calls for tenders include an additional 1000 MW of renewable wind power. 3 tabs., 4 figs

    Access to healthcare in remote areas is difficult and telehealth could be a promising avenue if accepted by the population. The aim of this study is to assess social acceptance and population confidence in telehealth in the Province of Quebec. We conducted a survey using a questionnaire assessing the social acceptance of and confidence level in telehealth. Two strategies were used: 1) paper questionnaires were sent to two hospitals in Quebec; and 2) online questionnaires were randomly sent by a firm specialized in online survey to a representative sample of the population of the Province of Quebec. Respondents were all residents of the Province of Quebec and 18 years and older. Questions were scored with a four-level Likert scale. A total of 1816 questionnaires were analyzed (229 written and 1,587 online questionnaires). The socio-demographic variables in our samples, especially the online questionnaires, were fairly representative of Quebec's population. Overall, social acceptance scored at 77.71% and confidence level at 65.76%. Both scores were higher in the case of treatment (3 scenarios were proposed) vs. diagnosis (p < 0.05). No difference was found when respondents were asked to respond for themselves and for a member of their family, which demonstrates a true interest in telehealth in Quebec. In addition, we found a significant difference (p < 0.05) between written and online questionnaires regarding social acceptance (80.75% vs. 77.33%) and confidence level (74.84% vs. 64.55%). These differences may be due to social desirability or avidity bias in the written questionnaires. Our results suggest that the population in Quebec encourages the development of telehealth for real time diagnosis and long distance treatment for regions deprived of healthcare professionals.

    Health or disease management (DM) has emerged as a promising solution to improve the quality of healthcare and patient outcomes in a cost-efficient way. This solution is particularly relevant in the care of our increasing, and aging, patient populations with multiple chronic diseases. This article reviews the recent history and current status of DM in the province of Quebec and summarizes its evolving perspectives and future prospects. Most DM projects in Quebec have developed from a public-private partnership, and they have addressed several disease states. The results of completed programs confirmed the presence of care gaps--the differences between best and usual care in several disease states. They also identified process changes leading to improved practices and enhanced professional satisfaction among stakeholders. Priorities identified for further research include increased knowledge of the underlying causes of care gaps and greater concentration on the measurement of clinical, humanistic and fiscal outcomes and their causal links to DM structures and processes. Although still embryonic in Quebec and Canada, the available evidence suggests that DM partnerships are practical and functional vehicles to expedite knowledge creation and transfer in the care of whole populations of patients. Future projects offer the promise of updated knowledge and continuously improved care and outcomes.

    A comprehensive study of the current status of the gasoline market in Quebec was presented. The study includes: (1) a review of the evolution of the retail market since the 1960s, (2) the development of a highly competitive sales environment, (3) a discussion of governmental interventions in the retail sales of gasoline, and (4) a discussion of the problems associated with the imposition of a minimum gasoline price. The low increase in demand for gasoline in Quebec since the 1980s has led to a considerable restructuring of the gasoline market. Consumers have little loyalty to specific brands but seek the lowest prices or prefer the outlets that offer the widest variety of associated services such as convenience stores, fast-food and car washes. Gasoline has clearly become a commodity in Quebec. An econometric model of gasoline price adjustments for the Montreal and Toronto urban areas and a summary of government interventions in the retail marketing of gasoline in Canada and the USA are included as appendices. tabs

    As a researcher, I have studied the efforts to increase the integration of health and social services in Quebec, as well as the mergers in the Quebec healthcare system. These mergers have often been presented as a necessary transition to break down the silos that compartmentalize the services dispensed by various organisations. A review of the studies about mergers and integrated care projects in the Quebec healthcare system, since its inception, show that mergers cannot facilitate integrated care unless they are desired and represent for all of the actors involved an appropriate way to deal with service organisation problems. Otherwise, mergers impede integrated care by creating increased bureaucratisation and standardisation and by triggering conflicts and mistrust among the staff of the merged organisations. It is then preferable to let local actors select the most appropriate organisational integration model for their specific context and offer them resources and incentives to cooperate.

  4. The take-over of Gaz Metropolitain by Hydro-Quebec

    Bernard, J-T.

    1997-01-01

    The implications of a take-over of Gaz Metropolitain by Hydro-Quebec in early 1997 and the pricing of electricity and natural gas in Quebec were discussed. In January 1997, Hydro-Quebec purchased all the shares in Noverco that were formerly owned by SOQUIP. With this purchase, Hydro-Quebec became the major share holder in Noverco, the company that controls Gaz Metropolitain. This type of take-over, where an electrical utility purchases the interests in a natural gas distributor, has also been observed in the United States and is believed to be a consequence of the recent deregulation of the electricity market. In the near future, it is believed that consumers will probably pay for equivalent energy use (like heating or cooling) rather than separate tariffs for electricity or natural gas consumption. The recent popularity of gas-fueled electrical cogenerating stations is also believed to be an important factor in this take-over. 1 ref., 3 tabs

  5. Marginal-cost pricing for Hydro-Quebec residential customers

    International Nuclear Information System (INIS)

    Paquin, C.

    1994-02-01

    An option available to governments and to utilities such as Hydro-Quebec for responding to objectives of energy efficiency is the adoption of marginal cost pricing. Compared to currently used price structures, marginal cost pricing will allow improvement of price signals and assure an optimal utilization of the resource. That type of pricing could be economically beneficial but may not be desirable from the point of view of revenue distribution. Taking account of Hydro-Quebec's cost structure, pure marginal cost pricing would generate an income that would be strongly contested on equity grounds. For example, it would raise prices 60% for residential customers. Faced with this possibility, an analysis is presented of the impact of a peak-offpeak pricing (or pure marginal cost pricing) on Hydro-Quebec's residential customer energy bills. The marginal costs of Hydro-Quebec are calculated by the method of Bernard and Chatel (1985) and analysis of the results is based on Friedman and Weare (1993). A sample of 28,417 residential customers from a 1989 Hydro-Quebec survey is used in the study. Two scenarios are analyzed; the first allowing comparison of the energy bill only on the basis of marginal costs and of average costs, and the second allowing comparison of the impact of marginal cost pricing on the total bill. In the first scenario, the impact translates into a 31% increase in energy bills for the entire customer class considered; in addition, this impact is inversely proportional to the revenue class. In the second scenario, the increase is 24%. 33 refs., 10 figs., 53 tabs

    Central Canada experiences numerous intraplate earthquakes but their recurrence and source areas remain obscure due to shortness of the instrumental and historic records. Unconsolidated fine-grained sediments in lake basins are 'natural seismographs' with the potential to record ancient earthquakes during the last 10,000 years since the retreat of the Laurentide Ice Sheet. Many lake basins are cut into bedrock and are structurally-controlled by the same Precambrian basement structures (shear zones, terrane boundaries and other lineaments) implicated as the source of ongoing mid-plate earthquake activity. A regional seismic sub-bottom profiling of lakes Gull, Muskoka, Joseph, Rousseau, Ontario, Wanapitei, Fairbanks, Vermilion, Nipissing, Georgian Bay, Mazinaw, Simcoe, Timiskaming, Kipawa, Parry Sound and Lake of Bays, encompassing a total of more than 2000 kilometres of high-resolution track line data supplemented by multibeam and sidescan sonar survey records show a consistent sub-bottom stratigraphy of relatively-thick lowermost lateglacial facies composed of interbedded semi-transparent mass flow facies (debrites, slumps) and rhythmically-laminated silty-clays. Mass flows together with cratered ('kettled') lake floors and associated deformations reflect a dynamic ice-contact glaciolacustrine environment. Exceptionally thick mass flow successions in Lake Timiskaming along the floor of the Timiskaming Graben within the seismically-active Western Quebec Seismic Zone (WQSZ), point to a higher frequency of earthquakes and slope failure during deglaciation and rapid glacio-isostatic rebound though faulting continues into the postglacial. Lateglacial faulting, diapiric deformation and slumping of coeval lateglacial sediments is observed in Parry Sound, Lake Muskoka and Lake Joseph, which are all located above prominent Precambrian terrane boundaries. Lateglacial sediments are sharply overlain by relatively-thin rhythmically-laminated and often semi

  7. Higher profits, lower bills : a new electricity strategy for Hydro-Quebec

    International Nuclear Information System (INIS)

    2010-01-01

    Quebec is the fourth largest producer of hydro-electricity in the world, and has among the lowest electricity rates in North America. In 2008, 89 percent of the electricity produced by Hydro-Quebec was sold in the province, and the remainder was exported. In 2009, the electric utility released its strategic plan for 2009 to 2013. Hydro-Quebec's net profits are forecast to decline by 24 percent by 2013 and electricity rates are forecast to rise by 8.5 percent. Since Hydro-Quebec has already developed all of the province's low-cost hydroelectric resources, it can no longer increase profits and lower rates by building new hydropower production stations. In order to continue to prosper, the utility will invest in energy efficiency and better coordination of its power system with Ontario's. Increased electricity exports from Hydro-Quebec will help both Ontario and the United States reduce their greenhouse gas emissions by displacing fossil power generation. 25 refs., 2 tabs., 3 figs.

    Recently, Chalifoux Dairy of Sorel, Quebec, invested, with the help of Hydro-Quebec, in three new technologies to increase the energy efficiency of the production line. A summary of these technological improvements was presented. The three new technologies were induction heating pasteurization, ultraviolet sterilization and ultrafiltration. Ultra-high temperature (UHT) induction heating is now used to pasteurize cream and chocolate milk. This new pasteurization method has reduced product returns from 5 per cent to nil. UHT cream is packaged in small disposable containers that are previously sterilized by a radiant ultraviolet source. An ultrafiltration method also has been implemented for production of specialty cheese at the dairy. This process yields 20 per cent more production with 30 per cent less energy than traditional methods. Hydro-Quebec assisted Chalifoux Dairy with a subsidy of $596,000 for these energy-efficiency modifications.

  14. Forecast electricity demand in Quebec: Development plan 1993

    International Nuclear Information System (INIS)

    1992-01-01

    Demographic, economic, and energy prospects are the determining factors in estimating demand for electricity in Quebec. In average scenarios developed for 1992-2010, the Quebec population will grow 0.5%/y and the gross domestic product will increase 2.6%/y. Firm electricity sales by Hydro-Quebec will grow to 197.9 TWh by 2010, or 2.2%/y. Sales in the residential and farm sectors should grow 1.3%/y and sales in the general and institutional sectors should rise by 2.2%/y. Electricity demand in the industrial sector, rising at an estimated 2.9%/y in 1992-2010, is chiefly responsible for the anticipated growth in Hydro-Quebec's overall sales. The nonferrous smelting, refining, chemicals, and paper industries will account for ca 60% of this growth. In the municipal services and public transportation sectors, demand should grow 3.3%/y, and over half the growth forecast in this sector can be attributed to the impact that new uses of electricity are expected to have after 2005. High- and low-growth scenarios offer alternative visions of demand growth based on different but equally valid assumptions about demographic and economic growth. In terms of firm electricity sales, the high- and low-growth scenarios differ by 50 TWh in 2010. Hydro-Quebec has retained two strategic orientations that will influence growth in electricity sales: the development of industrial markets and extension of the energy-savings objective of 9.3 TWh forecast to the year 2000. Taking these two orientations into account, the growth rate for electricity sales in the average scenario would be 1.8%/y rather than 2.2%/y. 25 figs., 81 tabs

  15. The implications of the nuclear option in Quebec

    Sauvageau, P.A.; Boivin, M.

    1979-10-01

    Problems concerning the nuclear option as a component of the energy balance of Quebec are presented. The demand for electrical energy for the periods 1977-1985 and 1985-2000, the energy resources of Quebec, and an analysis of nuclear fission energy are considered. In 1978 65.5 percent of Quebec's energy needs were supplied by imported petroleum, 7.1 percent by imported gas, and 1.4 percent by imported coal. Hydroelectricity supplied 21.9 percent of the energy budget in 1976. According to projections electricity's share will be around 41 percent in 1990 after conservation, and approximately 50 percent in 2000, while petroleum and gas will have 44 percent, new energies 5 percent, and coal 1 percent. The acceptability of nuclear power can be broken down into six factors, for each of which a decision criterion can be recognized: technical feasibility, economic feasibility, security of supply, side effects for Quebec, human and ecological risks, and socio-political factors. The first four criteria are acceptable and even in certain cases desirable. The acceptability of risks is subjective and should be a collective decision, and therefore is policitcal. Even if Quebec does not need nuclear at the present or in the next decade, it is still a form of energy which it will be necessary to come to terms with eventually. Thus it is important to maintain the capacity to have recourse to it, and to start a program of public dialogue by setting up a 'Permanent Council for Energy Forecasting'. The democratic participation of a well-informed population in a neutral and objective nuclear debate is thus essential. (LL)

  16. Fish habitat considerations associated with hydro-electric developments in Quebec region

    International Nuclear Information System (INIS)

    Bain, H.; Stoneman, M.

    2005-01-01

    Alternative approaches for evaluating the effects of 2 large Hydro Quebec proposed facilities on fish habitats were presented. The proposed projects will convert long stretches of river into water reservoirs and reduce the flow in the rivers below the impoundments for parts of the year. Rivers will be transformed into water reservoirs upstream by the dams, and a moderately large river will be transformed downstream into a much smaller river with a regulated flow. Productive capacity of fish populations is difficult to measure in large water bodies, and complications in the evaluation process have posed problems in the application of a traditional no-net-loss policy. It was suggested that estimates of biomass and productivity should be obtained from established methods of electrofishing combined with maps of the river and stream characteristics. For lakes and reservoirs, biomass and production will be estimated from models using a morphoedaphic index and measures of lake reservoir areas. Productivity will be partitioned among species according to surveys of existing lakes and reservoirs. It was also proposed that mitigation and compensation should be considered on a case-by-case basis related to importance of impact on fish production; geographic range of the impacts; regional fisheries management objectives for commercial, recreational, and subsistence fisheries and biodiversity conservation. Special attention will be given to listed species such as Atlantic salmon and lake sturgeon. Additional field sampling was recommended in areas impacted by the developments. Concerns about the technical methods used in sampling and monitoring data were reviewed, as well as issues concerning protected and unprotected species. It was suggested that predictive models of fish population characteristics will need to be parameterized for temperature ranges associated with the projects. It was noted that habitat suitability index methods do not consider the ecological flexibility

    This article recounted the experience of a 14-member Hydro-Quebec line crew and support group that travelled to Haiti in November 2004 to help re-establish essential electricity services. The work was conducted together with Electricite d'Haiti (EDH). The team installed 400 poles, 10 km of conductors and 85 transformers, restoring service to water pumps; La Providence and Raboteau hospitals; a centre housing Doctors without borders; a CARE distribution centre; and several convents and schools. The installation of street lights at strategic points allowed lighting to be restored in several districts of Gonaives. Hydro-Quebec was able to extend their mission to Haiti and purchase more poles and transformers with the help of a $500,000 contribution from the Canadian International Development Agency. Hydro-Quebec was the only company who came to the aid of EDH. The total budget for the project was $4 million. 2 figs.

    For approximately two years, several members of the Quebec branch of the Canadian Nuclear Society have publicly expressed their views in favour of nuclear energy in Quebec. This paper summarizes their participation in the BAPE public hearings on the environment ('Bureau d'Audience Publique sur l'Environnement'), in the hearings of a Quebec Parliamentary Commission on economy and labour, and in the United Nations Conference on Climate Change in December 2005 in Montreal. The focus is mainly on a debate around the possible refurbishment of the Gentilly-2 nuclear power plant, the only operating nuclear plant in Quebec. Antinuclear groups are well organized and their message is transmitted loudly to the public by the mainstream media. Industry professionals must therefore express themselves publicly to counterbalance this biased message. In conclusion, we see a need for the formation of a coalition of all who support nuclear power in Quebec to support the refurbishment of Gentilly-2. (author)

    2003-07-01

    Remote and nordic communities in Quebec include Inuit villages, the Lower North Coast, Anticosti Island, Magdalen Islands, and the James Bay region. Annual wind speed in each of these communities is more than 8.5 m/s which is ideal for wind power generation. However, wind energy projects that were underway have been abandoned for a variety of reasons. Hydro-Quebec has decided to invest in power lines to link villages in the Lower North coast. The electric utility is not interested in wind energy for the Magdalen Islands because of an existing large diesel power station. Likewise, Anticosti Island has a completely automated small diesel plant. Nordic Innu Villages are making money with fuel sales to Hydro-Quebec and have no economic interest in wind energy. Other barriers to development include a lack of government support and lack of interest in small wind projects. In addition, turbine manufacturers have not lobbied for wind energy development in Quebec's nordic communities. However, the potential exists for future development as innovations are rendering wind power more adaptable to community needs. Off-grid technology is also available. 2 figs.

    1993-09-01

    A cost-benefit analysis is presented of the energy conservation programs of Hydro-Quebec for 1991 to 2010. Three possible scenarios are simulated. In the first scenario, Hydro-Quebec data are used without modification. In the second, the simulation is carried out in the absence of the Hydro-Quebec programs, and in the third, it is assumed that any economies achieved are only for the short term. A comparison between these simulations allows determination of results concerning the advantages and the costs which the programs introduce for the three groups comprising society: the consumer, the producer, and the government. The results of these comparisons show that the consumer, the producer, and the whole society gain benefits from the energy conservation programs, while the government loses. 13 refs., 13 figs., 14 tabs

    Independent phenylketonuria (PKU) chromosomes (n=109) representing 80% of a proband cohort in Quebec province carry 18 different identified mutations in 20 different mutation/haplotype combinations. The study reported here, the third in a series on Quebec populations, was done in the Montreal region and predominantly on French Canadians. It has identified three novel mutations (A309D, D338Y, and 1054/1055delG [352fs]) and one unusual mutation/RFLP haplotype combination (E280K on Hp 2). The relative frequencies and distribution of PKU mutations were then compared in three regions and population subsets (eastern Quebec, French Canadian; western Quebec, French Canadian; and Montreal, non-French Canadian). The distributions of the prevalent and rare mutations are nonrandom and provide evidence for genetic stratification. The latter and the presence of eight unusual mutation/haplotype combinations in Quebec families with European ancestries (the aforementioned four and M1V, 165T, S349P, and R408W on Hp 1) corroborate demographic and anthropologic evidence, from elsewhere, for different origins of French Canadians in eastern and western Quebec. 29 refs., 1 fig., 1 tab.

    Antibiotic overuse and resistance have become a major threat in the last 2 decades. Many programs tried to optimize antibiotic consumption in the inpatient setting, but the outpatient environment that represents the bulk of antibiotic use has been challenging. Following a significant rise of Clostridium difficile infections, all the health care stakeholders in the province of Quebec, Canada initiated a global education program targeting physicians and pharmacists. A bundle approach was used; 11 user-friendly guidelines were produced by a group of experts and sent to all physicians and pharmacists in Quebec in January 2005. Downloadable versions of guidelines were posted on a dedicated Web site. They were promoted by professional organizations, universities, and experts during educational events, and there was strong acceptance by the pharmaceutical industry with a willingness to follow the recommendations in their marketing. The Intercontinental Medical Statistics (IMS) database was used to analyze and compare Quebec's total outpatient prescriptions per 1000 inhabitants with those in the other Canadian provinces for 2 time periods: preintervention (January 2003 to December 2004), and postintervention (February 2005 to December 2007). In 2004, antibiotic consumption per capita was 23.3% higher in Canada generally than in Quebec. After the guidelines dissemination, the gap between Quebec and the other Canadian provinces increased by 4.1 prescriptions/1000 inhabitants (P = .0002), and the trend persisted 36 months later. Antibiotic costs fell $134.5/1000 inhabitants in Quebec compared with the rest of Canada (P = .054). The implementation of guidelines significantly reduced antibiotic prescriptions in Quebec compared with the rest of the country, and there was a strong trend toward significant cost reduction.

    "This paper considers the evolution of French outside of Quebec and the English in Quebec.... The total historical set of national data on ethnicity, mother tongue, knowledge of official languages and home language [is first presented]. The 120 year stability showing French at around 30 percent of the national total is a function of compensating factors including high French fertility and high English immigration. During the 1960s both of these demographic supports disappeared and thus mobility across linguistic lines has become a particularly sensitive issue. "The picture with regard to French outside of Quebec has changed rather radically in the last thirty-five years. For instance, there was one French child to every nine in 1941 and one to every twenty-one children in 1976. While the English of Quebec were once represented in various parts of the province, their strength is now largely limited to the Montreal metropolitan area which includes 76 percent of the English mother tongue group. Outside of Montreal, the English amounted to 7.9 percent of Quebec's population in 1941 and 5.6 percent in 1976. The paper concludes with a discussion of the social factors that underlie these trends and their relevance to the models of institutional and territorial bilingualism." (summary in FRE) excerpt

  8. Canadian federalism and the Canadian health care program: a comparison of Ontario and Quebec.

    1987-01-01

    The Quebec and Ontario health insurance and health service delivery systems, developed within the parameters of federal regulations and national financial subsidies, provide generally universal and comprehensive basic hospital and medical benefits and increasingly provide for the delivery of long-term care services. Within a framework of cooperative federalism, the health care systems of Ontario and Quebec have developed uniquely. In terms of vital statistics, the health of Ontario and Quebec residents generally is comparable. In viewing expenditures, Quebec has a more clearly articulated plan for providing accessible services to low-income persons and for integrating health and social services, although it has faced some difficulties in seeking to achieve the latter goal. Its plans for decentralized services are counter-balanced by a strong provincial role in health policy decision-making. Quebec's political culture also allows the province to play a stronger role in hospital planning and in the regulation of physician income than one finds in Ontario. These political dynamics allow Quebec an advantage in control of costs. In Ontario, in spite of some recent setbacks, physician interests and hospital sector interests play a more active role in health system bargaining and are usually able to influence remuneration and resource allocation decisions more than physician interests and hospital sector interests in Quebec.

    Hydro-Quebec International (HQI) was established in 1978 as a wholly owned subsidiary of Hydro-Quebec. Its mission is to contribute to Hydro-Quebec's growth and profitability by investing in energy partnerships and by selling Hydro-Quebec expertise internationally. This annual report presents highlights of the company's operations, balance sheet, financial position, and investments. 1998 proved to be a year of market development and prospecting which yielded promising results. The expanded scope of the company that now includes investment and infrastructure construction was already generating $ 26 million in economic spinoff for Quebec. The report highlights HQI's involvement in Europe, the Middle East, Africa, and Asia. Great strides have been made also in ensuring the most rigorous practices possible to assess and manage risk and to bolster the company's ability to take unforeseen events in stride. On the investment side, in 1998, the first year of its involvement as an investor, HQI initiated investments amounting to $137 million. Plans are to double that figure in 1999. tabs., figs

    The high increase in mercury (Hg) concentrations in fish following the creation of hydroelectric reservoirs was discussed. Flooded forest soils are a major source of mercury contamination of fish after impoundment. Flooding stimulates bacterial activity in the humic horizon of soils and results in the transformation of inorganic mercury into methyl mercury (MeHg), the most toxic form of mercury. The reservoirs of the La Grande hydroelectric complex at James Bay in northern Quebec were sampled and compared to neighbouring natural lakes. Sampling was carried out in 1992 during June, August and September. Results of the analysis revealed an increase in the MeHg concentrations in zooplankton and suspended particulate matter (SPM); mean concentrations were about 5 times higher in the reservoirs than in neighbouring lakes. Although the process is not well understood, it is believed that the MeHg is transferred up the food chain which accounts, in part, for MeHg contamination of fishes. 45 refs., 9 figs

    Emergency departments are important safety nets for people who live in rural areas. Moreover, a serious problem in access to healthcare services has emerged in these regions. The challenges of providing access to quality rural emergency care include recruitment and retention issues, lack of advanced imagery technology, lack of specialist support and the heavy reliance on ambulance transport over great distances. The Quebec Ministry of Health and Social Services published a new version of the Emergency Department Management Guide, a document designed to improve the emergency department management and to humanise emergency department care and services. In particular, the Guide recommends solutions to problems that plague rural emergency departments. Unfortunately, no studies have evaluated the implementation of the proposed recommendations. To develop a comprehensive portrait of all rural emergency departments in Quebec, data will be gathered from databases at the Quebec Ministry of Health and Social Services, the Quebec Trauma Registry and from emergency departments and ambulance services managers. Statistics Canada data will be used to describe populations and rural regions. To evaluate the use of the 2006 Emergency Department Management Guide and the implementation of its various recommendations, an online survey and a phone interview will be administered to emergency department managers. Two online surveys will evaluate quality of work life among physicians and nurses working at rural emergency departments. Quality-of-care indicators will be collected from databases and patient medical files. Data will be analysed using statistical (descriptive and inferential) procedures. This protocol has been approved by the CSSS Alphonse-Desjardins research ethics committee (Project MP-HDL-1213-011). The results will be published in peer-reviewed scientific journals and presented at one or more scientific conferences.

    Full Text Available Very few Streptococcus suis infections in humans have been reported in Canada, although the condition is frequent in pigs. Meningitis, often accompanied by severe hearing loss, is the most common clinical manifestation. The disease is an occupational illness affecting persons in contact with pigs and may be underdiagnosed because of misidentification of the responsible bacterium. Since Quebec is the leading province for swine production in Canada, physicians and microbiologists should be aware of this infection, especially when a streptococcal meningitis is diagnosed in swine workers. The first case of S suis type 2 meningitis reported in Quebec is described.

    Quebec's natural gas industry is poised to expand as a result of a breakthrough well drilled in the Utica shale gas play in February 2010. The well has produced more than 12 million cubic feet per day. The Quebec Oil and Gas Association (QOGA) was formed in 2009, and has lobbied the provincial government to keep royalty rates at between 10 to 12.5 per cent. A task force has also been deployed to ensure the development of a prompt regulatory process. It is hoped that increased investment will encourage more drilling activity in the province. Quebec consumes approximately 200 billion cubic feet of natural gas per year. Increased sales are expected to come from new residential construction, where 1 in 5 homes are now being equipped with gas-fired heating. The QOGA is currently designing a training program for potential rig workers. Studies have indicated that gas royalties collected by the provincial government could exceed $1 billion per year in the future. 1 fig.

    1991-01-01

    Higher than expected electricity consumption in recent years and increasing objections to capacity expansion on environmental grounds have led Quebec's government-owned electric utility, Hydro-Quebec, to launch an innovative program to reduce peak period residential electric heating demand. When the outside temperature drops below -12 degree C, customers who have opted for the program are charged 10 cents/kWh for their electricity (substantially above the 4.46 cents/kWh paid by normal residential customers) and they are automatically switched to a non-electric heating source, whereas above -12 degree C they pay 2.75 cents/kWh for all uses. A cost benefit analysis of this dual energy program finds that if, as Hydro-Quebec forecasts, 150,000 residential customers were to opt for this program, they would benefit by $19.0 million per year, while the utility and the government would lose $21.6 million and $1.6 million respectively, with a total net loss to Quebec society of $4.25 million a year. 12 refs., 4 figs., 6 tabs

    Progress in providing services, in financial and human relations management aspects, and future outlook for Hydro-Quebec was summarized in the 1995 annual report. Environmental policy of the Corporation was updated to reflect international concepts of sustainable development and environment management. A program was launched to remove, recycle and eliminate contaminants. Although generating systems will not be expanded between 1997 and the year 2000, existing generating facilities will be revitalized to improve their capacity and performance. As part of aggressive marketing of surplus capacity abroad, the creation during the past year of the first U.S. subsidiary, HQ Energy Services, was announced. Net income for the year was reported at $390 million, decreased by $277 million since 1994, due to financial pressure created by the commissioning of installations, including those at Phase II of the La Grande complex, and the slowdown in electricity sales in Quebec. A net income of close to $500 million was forecast for 1996. To achieve this target the Corporation announced plans to reduce operating expenses, an exercise which will include staff reductions and a wage freeze. tabs., figs

    1993-01-01

    Results are presented from a study concerning the potential of photovoltaic (PV) energy in Quebec to the year 2010. The different PV applications which are or will be economically viable in Quebec for the study period are identified and evaluated in comparison with the conventional energy sources used for these applications. Two penetration scenarios are proposed. One considers little change at the level of policies established for commercialization of PV sources, and the other considers certain measures which accelerate the implementation of PV technology in certain niches. While the off-grid market is already motivated to adopt PV technology for economic reasons, it is forecast that all encouragement from lowering costs would accelerate PV sales, offering a larger purchasing power to all interested parties. Above all, lowered PV costs would open up the network market. Photovoltaics would have access to a much larger market, which will accelerate changes in the very nature of the industry and bring with it new reductions in the costs of producing PV systems. 5 refs., 1 fig., 7 tabs

    Although it is believed that the information economy is replacing the mass economy, many companies continue to grow on economies based on natural resources. Recent aggressive growth by Hydro-Quebec in the highly competitive market for energy products was singled out as one of the success stories. Among other things, Hydro-Quebec was reported to focus attention on the globalization of electricity products, particularly in Asia, Europe and Africa. The corporation was said to cooperate with other utilities companies such as Ontario Hydro and Power Asia Assets Corporation to diversify its markets abroad. Hydro-Quebec is also marketing new products, developed in its laboratories and by subsidiaries, such as power system simulators and power system planning and management systems, on a global scale

A geographic information system database was used to characterize the food environment around a sub-sample of 374 public schools in which 26 655 students were enrolled. The outcome variable was JCL during the previous week, dichotomized into low JCL (none or once) v. high JCL (twice or more). Access to fast-food outlets near school was assessed using an existing database of fast-food outlets in Quebec. Covariates included student (age, sex and self-rated perceived health), family (familial status and parental education) and school (urban/rural status and deprivation) variables. Hierarchical logistic regression models were employed for analyses using PROC GLIMMIX of SAS version 9.3. Province of Quebec, Canada. We used data from the Quebec Health Survey of High School Students (QHSHSS) 2010-11, a survey of secondary-school Quebec students. Exposure to two or more fast-food outlets within a radius of 750 m around schools was associated with a higher likelihood of excess JCL (OR=1·50; 95 % CI 1·28, 1·75), controlling for the characteristics of the students, their families and their schools. The food environment surrounding schools can constitute a target for interventions to improve food choices among secondary-school children living in the province of Quebec. Transforming environments around schools to promote healthy eating includes modifying zoning regulations that restrict access to fast-food outlets around schools.

    2011-01-01

    This essay focuses on the liberalization of electricity markets in Quebec and France. As in most Western states, Quebec and France have undertaken reforms to liberalize their domestic electricity markets. Starting from a similar arrangement, namely occupied by a state monopoly, the French and Quebecois markets have evolved into a more or less liberalized model. What were the changes brought about by these reforms? What reasons have motivated them? What is the functioning of the model in place in both states? What are the prospects for these markets? To identify the issues of these reforms, this essay will be divided into four chapters. The first chapter will discuss the organization of markets in Quebec and French before the liberalizing reforms: in addition to the organization as such, this chapter will address the reasons why the two states have chosen a market controlled by the state. It emerges from this chapter that both states nationalized and regulated the electricity market to promote economic development and quality standards for a service considered public. The second chapter will examine the genesis of liberalization reforms, the different models of market organization and a summary of selected experiences of liberalization that took place both before those of Quebec and France ones. The diversity of market models and the pitfalls have lived through some states raised the fact that successful liberalization reforms is a complex process. The third chapter will analyse the reforms that changed markets in Quebec and France and more specifically, the organization of the market that has resulted. It is established that if the two markets have been forced to reform themselves by forces outside the two states, the paths that were taken differ greatly. Finally, the fourth chapter will conduct an initial assessment of the reforms and provide some forecast for the future. The reforms that have taken place in both states have produced satisfactory results taking

    The study of the cumulative environmental effects that have been integrated with technical and economic analyses include mercury, land use in the region (territory), natural landscapes, cultural heritages, forest dynamics, regional economies and ways of life. Requests and petitions from the public about Hydro-Quebec projects fall into four categories: welfare of communities, impact on the land, environmental responsibility and preservation of plant and animal species. The cooperation of all concerned is necessary for Hydro-Quebec's developments. (author)

Data from interviews with key members of [the Ministry of Immigration] and from selected documents are drawn on to illustrate Quebec's cultural politics. The Quebec position on the question of immigration as it has evolved in the context of immigration policies defined by the federal government in Ottawa is examined.... In particular, the present article considers how attempts to construct a cultural identity and a nation-state in Quebec have had important consequences for immigration policy and for attitudes and policies concerning Quebec's cultural minorities.

  6. Hydro-Quebec and energy efficiency

    International Nuclear Information System (INIS)

    1990-01-01

    There is growing awareness that energy efficiency is both profitable and environmentally beneficial. In this year's Development Plan, Hydro-Quebec is proposing an Energy Efficiency Project made up of marketing programs designed for all markets throughout the final decade of the 20th century. This Project will have two aspects: energy efficiency and consumption management. Hydro-Quebec aims to reach an energy-efficiency level of 12.9 terawatt hours per year by 1999, fully 55% of its 23-terawatt hour potential. Over the next 10 years the utility intends to spend $1.8 billion for this purpose. Cumulative anticipated energy savings should be in the vicinity of 70 terawatt hours for the coming decade, and more than 130 terawatt hours for the first decade of the next century. Of the overall goal of 12.9 terawatt hours for Horizon 1999, energy savings of 9.0 terawatt hours should be the direct result of this year's proposed marketing programs, and will account for the bulk of anticipated investments. The remaining 3.9 terawatt hours will be gained as customers acquire better electrical appliance and accessory (household appliances, home insulation) buying habits

  7. Hydro-Quebec's buyback tariff

    Richard, J.C.

    1992-01-01

    Hydro-Quebec had an installed electric generation capacity of 25,682 MW in 1990, of which 23,927 MW was hydraulic. Of the 26 thermal power plants, 22 are in remote communities on islands or in the north part of the province. The utility's development plan predicts an annual growth in demand of 2.6% to reach ca 200 TWh in 2006; this demand would be reduced to ca 180 TWh by energy efficiency measures. To increase capacity, Hydro-Quebec can utilize the hydro generation potential of its large rivers, of which 18,000 MW is economically viable, and its small rivers. Of the 10,000 MW theoretical potential of the latter, a large fraction cannot be economically developed under existing conditions. The utility has a policy to purchase energy as a function of the price of fossil fuel. For wind energy, this price was 4.22 cents/kWh in 1991; this price will be increased annually according to the inflation index. In its isolated sites such as the Magdalen Islands, current costs of diesel-generated electricity are at least 5.5 cents/kWh. There are possibilities for installing wind plants in isolated regions but their automatic control systems need to be improved for achieving a larger utilization factor relative to diesel generation and their cost needs to be reduced. 1 tab

    To assess the pharmacovigilance perception of Quebec's hospital pharmacists. Cross-sectional study. A questionnaire with 16 questions was developed in order to assess respondents' perception of their ability to practice pharmacovigilance, factors that can influence adverse drug reactions reporting and measures to increase reporting rate. The online questionnaire was sent to hospital pharmacist from Quebec in April 2014. The results were presented in the form of descriptive data. A total of 179/252 (71%) hospital pharmacists responded. More than 90% of respondents considered that they were able to practice all activities related to pharmacovigilance. During one year of practice, 98% of respondents faced at least one serious or unexpected adverse drug reaction and 77% notified at least one adverse drug reaction to Health Canada. The factors encouraging more than 89% of respondents to notify were: the severity, the rapidity of onset, the visibility of the reaction, the fact that the adverse drug reaction was unexpected or due to a recent marketed drug. More than 69% of respondents considered the overwork as the principal obstacle to the notification. The majority of respondents supported the implementation of 13/14 measures in order to increase reporting rate. Hospital pharmacists from Quebec presented a favorable ability to practice pharmacovigilance. Analysis of their perception of pharmacovigilance helped to identify improvements, such as the implementation of a pharmacovigilance coordinator in the health center.

    Numerous studies utilizing remote sensing imagery and other methods have documented that thermokarst lakes are undergoing varied hydrological transitions in response to recent climate changes, from surface area expansion to drainage and evaporative desiccation. Here, we provide a synthesis of hydrological conditions for 376 lakes of mainly thermokarst origin across high-latitude North America. We assemble surface water isotope compositions measured during the past decade at five lake-rich landscapes including Arctic Coastal Plain (Alaska), Yukon Flats (Alaska), Old Crow Flats (Yukon), northwestern Hudson Bay Lowlands (Manitoba), and Nunavik (Quebec). These landscapes represent the broad range of thermokarst environments by spanning gradients in meteorological, permafrost, and vegetation conditions. An isotope framework was established based on flux-weighted long-term averages of meteorological conditions for each lake to quantify water balance metrics. The isotope composition of source water and evaporation-to-inflow ratio for each lake were determined, and the results demonstrated a substantial array of regional and subregional diversity of lake hydrological conditions. Controls on lake water balance and how these vary among the five landscapes and with differing environmental drivers are assessed. Findings reveal that lakes in the Hudson Bay Lowlands are most vulnerable to evaporative desiccation, whereas those in Nunavik are most resilient. However, we also identify the complexity in predicting hydrological responses of these thermokarst landscapes to future climate change.

    The Centre d'Expertise Hydrique du Quebec (CEHQ) manages dams used for flood control, water supply, recreational activities and hydroelectricity in the province of Quebec. This paper addressed the issue of global warming and the impact on the hydrological regime within the next decades. The changes in the hydrological regime may pose a risk of losing the equilibrium between various objectives, identifiable through water management plans. The CEHQ conducted a pilot study for the Saint-Francois and Aylmer reservoirs in order to formulate a method for evaluating the adaptability of currently used management plans to climate change. The project was based on potential climate change scenarios as well as on deterministic and distributed hydrological models. Daily time steps were used to evaluate the hydrological impacts of climate change. The newly developed model makes it possible to evaluate and compare the occurrences where stream flows and water levels exceed critical values. The effectiveness of the management plans in both current and climate change scenarios was evaluated. Preliminary results suggest a possible increase in flood risk and fewer low water level occurrences. It was concluded that climate change will influence the trade-off between different management objectives of the reservoirs. Although adaptation measures may be feasible, it was determined that there is no unique solution to all climate change scenarios. 27 refs., 7 tabs., 12 figs.

    This paper provides an overview of the wind resource assessment programme undertaken by the provincial power utility Hydro-Quebec, in Quebec, Canada. The methodology used in different phases of the project is enunciated and explained and the results discussed. Supplementary studies of airflow over complex terrain using numerical modelling are described and the results evaluated. Since the program is still far from completion, conclusive statements cannot, at this time, be made about the viability of the wind energy resource. However, tentative conclusions are that wind energy as an alternate source of energy for the province is likely to be commerciaally viable since two of the most important requirements viz, the presence of a good wind regime and the availability of suitable land are satisfied in many regions.

    1996-01-01

    The current status of biomass energy in the Province of Quebec was reviewed. For electrical energy production uses, biomass combustibles include peat, forestry, agro-food and urban waste products. These materials are used directly as combustibles in the production of electricity, or are first processed through gasification, pyrolysis, anaerobic digestion or fermentation into combustible products. In Quebec, 176.2 MW of electricity is produced yearly from biomass materials, mostly waste products of the forestry industry. New biomass avenues are actively being explored, including bio- gases produced from municipal landfill sites, gasification of used automobile tires and combustion of demolition waste. Although their contribution is minimal, biomass materials can nevertheless contribute a few hundred megawatts of energy to the Province's overall energy budget. 2 figs

    1992-01-01

    A historical account of the development of the chemical industry in Quebec from the year 1800 to the present was presented. The emphasis was on the development of the petrochemical industry after 1945. The earliest signs of chemical manufacturing in Quebec appeared in 1800 with the opening of the Wadsworth and Lyman pharmaceutical laboratories followed by several manufacturers of soap, paint, sugar, rubber, cement and explosive products. In 1900 the acetylene-based carbon chemistry industry was established in the Shawinigan region. The petrochemical industry in Quebec was born in 1952 with the opening in Montreal of a cumene and phenol plant by Shawinigan Chemicals and British American Oil, peaking in 1976 with six producing refineries in east Montreal. At that time, Montreal represented the largest refining centre in Canada with a combined capacity of 600,000 barrels per year. Since then, four of these refineries have closed but the province remains an important centre particularly in the manufacturing of oil-derived plastic products. Tables and maps showing the development and distribution of petrochemical manufacturing and the location of oil pipelines in the Montreal area, at various times since 1946, are included. 11 figs

    2002-01-01

    The nature of the industrial market in Quebec was described along with a look at the competitive positioning of industrial electricity prices in the province. A discussion of the interventions made by the Association Quebecoise de Consommateurs Industriels d'Electricite (AQCIE) and the Association des Industries Forestieres du Quebec (AIFQ) for improving the competitiveness of industrial prices was provided. The plan designed to ensure the security of supply was reviewed, and advice was offered on ways to minimize the price increases, namely in the transmission, in the demand for review of transmission cost, and production. The author indicated that Hydro-Quebec was proposing the uniform cost structure without specific allocation of cost to the various functions of the network depending on the services offered. The proposed alternative is a grouped cost structure which would better reflect the costs incurred linked to the effective utilization of each of the major functions of the network. The author proposed an interim rebate of 25 per cent. Under the rebate policy, the author stated that the rebates must promote the optimum utilization of the network and the maximization of revenues rather than discouraging its use. tabs., figs

    The growing concern regarding the long-term contribution of freshwater reservoirs to atmospheric greenhouse gases (GHG), led Hydro-Quebec, to study net GHG emissions from Eastmain 1 reservoir, which are the emissions related to the creation of a reservoir minus those that would have been emitted or absorbed by the natural systems over a 100-year period. This large study was realized in collaboration with University du Quebec a Montreal, McGill University and Environnement IIlimite Inc. This is a world premiere and the net GHG emissions of EM-1 will be presented in details.

    This report provides a consolidated review of the operations of Hydro-Quebec, with a focus on energy production, energy sales, and environmental commitment. Hydro-Quebec is a major producer, transmission provider and distributor of electricity, conducting research and promotional activities in energy and energy transformation and conservation. The Quebec government is its sole shareholder. The company is divided into six divisions and now competes freely with other power producers, while its transmission and distribution remain regulated. Sales totalled $10.7 billion, up 1.8 per cent over 2003. Net income rose to $2.4 billion, up $497 million over 2003, the increase being largely due to lower financial expenses and the disposal of interests in Noverco. Dividends declared amounted to $1.3 billion, or 55 per cent of net income. Cash from operations totaled $4.0 billion, Sources of revenue also included the sale of interests in Noverco, and investment in Meiya Power Company, with the consequent repayment of nearly $1 billion in debt. Major projects of 2004 included the start of operations at the Rocher-de-Grand-Mere generating station as well as work proceeding on Eastmain-1, Peribonka, Toulnustouc and Mercier. Other projects included a partnership with the Crees of Eeyou and the filing of the Energy Efficiency Plan 2005-2010. This annual report presented the company's financial performance, executive changes and reorganization. Financial statements included a review and analysis of financial transactions, the auditor's report as well as customary notes to the consolidated financial statement including balance sheets, assets, liabilities and capital. tabs., figs

    2010-11-01

    This document presented an inventory of greenhouse gas (GHG) emissions produced by human activity in Quebec between 1990 and 2008. In 2008, 82.7 Mt of carbon dioxide (CO 2 ) equivalent were released in Quebec, which represents a 1.2 percent reduction from 1990 levels. Quebec had the second lowest GHG emissions per capita in 2008 and was 1 of only 3 only provinces in Canada to have a reduction in GHG emissions since 1990. This document also presented data regarding GHG emissions released by sector, notably from industrial combustion such as the TransCanada Energy cogeneration facilities; industrial processes; residential, commercial and institutional buildings; agriculture; sanitary landfills; and electric power production. Quebec's reduction in GHG emissions can be attributed primarily to advances in energy efficiency technology that have been adopted by the industrial sector. In addition, some industrial combustion facilities have been closed and landfill facilities have begun to use systems to capture methane gas. In contrast, automobile traffic increased over the study period, and was responsible for an important increase in GHG emissions since 1990. 6 tabs., 4 figs.

    In 2006, Hydro-Quebec introduced a large DSM program on the market to promote the adoption of compact fluorescent lamps in Quebec households. After 3 years of program implementation, there was significant indication on the part of market actors that the promotional campaign component was quite effective in transforming the Quebec market. Hydro-Quebec therefore decided to modify its approach to program evaluation to include the quantification of market effects. Econoler led a team including American partners, Opinion Dynamics Inc. and Megdal and Associates to conduct an evaluation of program impacts on market transformation. An evaluation strategy was designed where different research tools would be integrated to determine market evolution over the two previous years. Each research method was used to determine an estimate of program impacts, then triangulated with other approaches to determine the most appropriate impact evaluation method regarding the Hydro-Quebec program. Research efforts included a non-participant survey, interviews at manufacturer headquarters across Canada, interviews with banner distributor representatives across Canada, the collection of sales and market share data from manufacturers and retailers as well as secondary research to identify other players that could influence the market. The evaluation revealed that savings of 168 GWh could be attributed to direct and indirect impacts of the program for the 2006-2007 period.

    Full Text Available The paper examines the main reasons for the emergence and spread of Quebec swearing (les sacres. Socio-psychological aspects of their origin and distribution in the Quebec dialect of the French language are analyzed. It is established that after the Silent Revolution (Révolution tranquille of the 6070s of the 20th century, the influence of the Catholic Church in Quebec was minimized, so the “les sacres” lost their original meaning and no longer bear a religious connotation. Various variants of classification of mechanisms of word-formation “les sacres” are also given in the work. Separately, the classification proposed by André Bugaev has been singled out, within the framework of which the mechanisms of the word-formation “les sacres” are discussed in detail. With its use, it is suggested to perform a linguistic analysis of the retrospective of the word-formation system “les sacres” and to establish a relationship with socio-political factors.

    "In this paper the author presents a study of the spatial mobility of the Quebec population between 1966 and 1976, in the light of regional capitalist development. Based on an empirical operationalization of the concepts of mobility and development, the author demonstrates that Quebec presents a very irregular distribution of its poles of development over its territory, and that the mobility of the work force is in the image of this distribution. A few regions within the Montreal metropolitan area have attained a relatively evolved state of capitalist development and consequently are able to attract within their limits a large majority of migrants moving inside of or toward Quebec. In contrast, it can be observed that the majority of the regions in Quebec may be qualified as 'underdeveloped', and that their net mobility figures are negative." (SUMMARY IN ENG AND SPA) excerpt

    The West and East Clearwater Lake impact structures are two of the most distinctive and recognizable impact structures on Earth. Known regionally as the "Clearwater Lake Complex", these structures are located in northern Quebec, Canada (56 deg 10 N, 74 deg 20 W) approximately 125 km east of Hudson Bay. The currently accepted diameters are 36 km and 26 km for the West and East structures, respectively. Long thought to represent a rare example of a double impact, recent age dating has called this into question with ages of approximately 286 Ma and approximately 460-470 Ma being proposed for the West and East structures, respectively. Relatively little is known about the East Clearwater Lake structure. There is no surface exposure and what information there is comes from geophysics and two drill cores obtained in the 1960s. In contrast, the West Clearwater Lake structure is relatively well preserved with large ring of islands in the approximately 30 km diameter lake. Much of the work done on West Clearwater stems from field investigations carried out in 1977 driven by the Apollo program, with a focus on the impact melt rocks and other impactites, which are well exposed on the ring of islands. To our knowledge, the Clearwater Lake impact structures have not been the focus of detailed impact geology field investigations since the 1977 expedition and the only geological map that exists is from the 1960s and is at the reconnaissance level. Our knowledge of impact cratering processes have increased substantially since this time, as have the analytical techniques available for samples. This provided the motivation for a joint Canadian-US-UK expedition to the West Clearwater Lake impact structure in August and September 2015, under the auspices of the FINESSE (Field Investigations to Enable Solar System Science and Exploration) project, part of NASA's Solar System Exploration Research Virtual Institute (SSERVI). We focus here on the impactites of the West Clearwater Lake

    Congenital anomalies are the consequence of a complex interaction between genetic predisposition and fetal environment. Based on the Congenital Anomalies Surveillance in Canada Report, between 1998 and 2007 the rate of congenital heart defects in Quebec was significantly higher than the Canadian average; no data on the overall prevalence of congenital anomalies for Quebec or data on regional variations in any province are available. To estimate the prevalence of major congenital malformations (MCMs) in all of the 17 administrative regions of Quebec. Using data from the Quebec Pregnancy Cohort, we included infants if they were born between January 1, 1998 and December 31, 2008. MCMs were identified within the infant's first year of life using validated ICD-9 and ICD-10 codes. The rate of MCMs was calculated and stratified on Quebec's administrative regions. Among 152,353 eligible infants, the prevalence of MCMs was 36.6 (all rates were reported as per 1,000 live births). The regions with the highest rate of MCMs were Lanaudière (48.1), Laval (45.8), and Mauricie (45.1). Regions with the lowest rate were Outaouais (13.4), Côte-Nord (19.1), Abitibi-Témiscamingue (27.5), Gaspésie-îles-de-la-Madeleine (27.9), and Saguenay-Lac-Saint-Jean (28.9). Congenital heart defects (10.3) and musculoskeletal anomalies (12.6) were the most common. Laval had the highest rate of heart defects (16.1), and Lanaudière had the highest rate of musculoskeletal anomalies (22.0). The central regions of Quebec had high rate of MCMs, whereas the relatively genetically homogenous peripheral regions of Quebec had lower rate of MCM, suggesting the importance of fetal growth environment in the etiology of MCMs in Quebec.

    Understanding effects of location and timing of harvest seasons on mortality of ducks and geese from hunting is important in forming regulations that sustain viable waterfowl populations throughout their range. During 1990 and 1991 we alternately marked 80 hatching year (HY), female mallards along the Vermont–Quebec border; half with radio-transmitters and bands and half with only aluminum leg bands. We monitored radio-marked ducks daily and recorded survival status weekly for 15 weeks from August until December each year. Mallard mortalities began 25 September when the hunting season opened in the Province of Quebec, Canada. Overall survival of mallards at week 10 did not differ between years (0.51 in 1990 vs. 0.43 in 1991) or differ from that of HY American black ducks (0.44 females, 0.42 males) based on proportional hazard analysis in a Bayesian framework. The mortality rates for mallards from hunting (0.47) and causes unrelated to hunting (0.06) were similar between years and to those rates for HY black ducks at that same site. Hunter harvest accounted for most of the mortality recorded during this study and illegal feeding (i.e., baiting) at sites just before and during the hunting season was observed. Females with lower body condition index had greater mortality rates; a 1-standard-deviation increase in condition index would reduce mortality hazard by about 29%. Management options that may increase mallard survival in the area include lowering daily bag limit in Quebec and suspending split hunting seasons in Vermont that increase harvest, delaying opening date of hunting in Quebec to allow for increased body condition before hunting season opens, and improving enforcement of baiting restrictions.

    Human papillomavirus (HPV) infections are the most common sexually transmitted infections in North America and are associated with cervical cancer. A publicly-funded HPV immunization program was launched in the province of Quebec, Canada, in the fall of 2008. The aim of this study was to explore factors associated with HPV immunization among young adult women not targeted by this program. A questionnaire was mailed to 2400 24-y-old women randomly selected from the Quebec provincial health insurance database and 56% responded. Factors associated with vaccination status were analyzed using a multivariate logistic regression model. Few women had received at least one dose of HPV vaccine among the 1347 respondents. Age at first sexual intercourse ≥ 20 y, participating in cervical cancer screening, higher education level, being born in Quebec and some positive beliefs about HPV were associated with vaccination. The rate of immunization in women who had to pay for the HPV vaccine was very low and was associated with characteristics that are generally associated with a lower risk for HPV infection and cervical cancer. Efforts are needed to reach at-risk adult women.

    Studies that are underway at OURANOS indicate that some of the probable climate change scenarios in the coming years will have an effect on Quebec's watersheds hydrology and on temperatures. For Hydro-Quebec, who draws more than 95% of its generation from hydraulic resources and whose electricity loads depend pretty much on temperatures, such climate changes will definitely have a significant impact on many aspects of the planning and operations of its system. Our presentation will be divided into three parts. First, to bridge the gap between climate change scientists and water managers, we will present a list of the types of parameters needed from the scientists in order for the water managers to assess the impacts of climate changes on a hydroelectric system such as Hydro-Quebec's. These parameters will include changes in annual and seasonal distribution and variability of natural inflows and, most importantly, the timing of the changes in the coming years. The second part will focus on the types of adaptive decisions and strategies that will have to be taken ahead of time in order to implement the changes on a hydroelectric generation system such as Hydro-Quebec's. They will cover different areas such as generation planning, operations planning and optimization, refurbishment and replacement of infrastructures, dam safety, flood control and protection, maintenance planning and reliability. Finally, we will present more specific results of the impact of some climate change scenarios on Hydro-Quebec's overall generation system, showing differences between regions, and a case study on one of its river systems.

  12. The 12th 735-kV transmission line project: Hydro-Quebec network

    International Nuclear Information System (INIS)

    1992-01-01

    Hydro-Quebec is proposing to construct a 735-kV transmission line from the Chissibi station near the LG3 hydroelectric power plant to the Jacques-Cartier station near Quebec City. The width of the right-of-way will generally be 90 m and it is intended to install the line in two stages. The Chissibi-Chibougamau section should enter service in 1993 and the Chibougamau-Cartier section in 1994. The cost of the line is estimated at $1.21 billion, of which $900 million is for line construction and $310 million for station equipment. Prospective corridors for the line route have been selected, portions of which enable twinning with Hydro-Quebec's existing 9th 735-kV line. A series of hearings on the environmental and other impacts of the power line project was held by the Bureau d'audiences publiques sur l'environnement and results are summarized along with the views of the Bureau. The summary describes the justification for the project, the choice of the transmission line route, the evaluation of the impacts of the project on the natural and human environments, health effects due to magnetic fields, and effects on the economic development of northern Quebec. Recommendations are given for mitigating the impacts of the project. 13 refs., 8 figs., 2 tabs

    In the last years, Hydro-Quebec it undertook an important program to improve the dependability of their net of energy transport. They concentrated the efforts on increasing the capacity of the net resist in the event of carries to an extreme contingency caused in general by multiple incidents or for successive disconnection of the lines of energy transport. To neutralize these contingencies, Hydro-Quebec it adopted a series of special measures that are contained under the general title of Plan of Defense for Extreme Contingencies. The objective of this plan is to detect the incidents that surpass the capacity of the net. It is completely automatic and it is based mainly in: A system of automatic disconnection of generation and tele-shot of loads; A system of automatic maneuver (opening and closing) of inductances shunt of 735 kw; A system of disconnection of loads for low voltage; A system of disconnection of loads for low frequency. The present document summarizes the orientations that there is taking Hydro-Quebec to protect its net in the event of extreme contingencies and it describes the different automatism that they are adopts, in particular the system automatic disconnection of generation and tele-shot of loads (RPTC) that is one of the main components of the defense plan. The system RPTC detects the simultaneous loss of several lines directly in 15 substations of 735 kw. It understands four places of automatic disconnection of generation and a centralized system of tele-shot of loads

    In December 1993, Hydro-Quebec launched an ambitious direct installation program known to the public as Econo-Confort. The program is aimed at reducing electricity consumption by residential customers. In the period 1994-1997, Econo-Confort representatives will visit Quebec's 2,8 million homes individually and offer to install energy-saving products such as electronic thermostats and low-flow shower-heads, at no charge to customers. The program's objectives are astronomical: 8 million thermostats and 800,000 shower-heads will be installed in 1.1 million households, for total energy savings of 2,010 GWh. Planning such an extensive operation demanded an equally extensive performance analysis, covering the technology, consumer behaviour and commercial strategy aspects. (author)

  16. Quebec industry and climatic changes : Quebec Industry Working Group on Climatic Changes

    International Nuclear Information System (INIS)

    2001-03-01

    Global climatic change is a phenomenon greatly influenced by greenhouse gas emissions resulting from human activity and the natural greenhouse effect necessary to sustain life on the planet. Carbon dioxide emissions in the atmosphere now exceed the levels prior to the industrial revolution by 31 per cent. Half of this increase occurred during the past 30 years, while the average temperature increased by 0.3 to 0.6 degrees C. By using climate change models, scientists have linked this increase to the increase in the concentration of carbon dioxide in the atmosphere and predict that the average temperature will rise by 1 to 3.5 degrees C during the next century with increases of 5 to 10 degrees C being felt in certain parts of Canada. In an effort to curb the emissions of carbon dioxide, the Quebec Industry Working Group on Climatic Change was created to represent different sectors of the industry, including energy, metallurgy, aluminium, cement, environment, mines, plastics, petrochemicals, pulp and paper, and manufacturing. The group worked at meeting the following objectives: (1) to examine the possibilities of reducing greenhouse gases emissions in the industrial sector, (2) to propose and evaluate measures and initiatives for the reduction of greenhouse gases emissions including their cost, impact and potential timetable for implementation, (3) to identify new and promising technologies in the field of greenhouse gases reduction, (4) to identify business opportunities and risks for industry in Quebec, and (5) to recommend an implementation strategy for the Kyoto Protocol for each sector, in terms of reduction measures that would be economical and in agreement with the various plans in place at the federal, provincial and municipal levels. A total of 22 recommendations were proposed covering the entire spectrum of the mandate. 15 tabs, 2 appendices

A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human–environment interactions (for example, climate change, for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change in multi-actors contexts has progressively been

    In June 2000, the federal and provincial governments, with the exception of Quebec, adopted a Canada Wide Standard (CWS) for particulates and ozone and set out to reduce these pollutants by 2010. Although Quebec was not a signatory to the CWS, it acts in coherence with the other governments regarding these air quality standards. Ozone and particulates are the main precursors to smog and are known to cause health and environmental problems. Ozone forms when nitrogen oxides and volatile organic compounds (VOCs) chemically react, particularly during hot sunny days. The CWS is a strategy to reduce the risk of these pollutants to public health and the environment. In order to apply this standard, Quebec must verify conformity for regions with a population of more than 100,000, which includes 6 regions, notably Montreal, Quebec City, Gatineau, the Saguenay, Sherbrooke and Trois Rivieres. Results of a 2008 study showed that air quality in Gatineau and 3 subregions of Montreal exceeded the allow limit of 65 ppb for ozone. However, ozone concentrations in Quebec City, the Saguenay, Sherbrooke and Trois Rivieres were under the allowable limits. Results of the 2008 study showed that particulate concentration in all regions were blow the allowable limits. This document revealed that there has been an improvement in air quality in terms of ozone and particulates since 2005. Most regions in Quebec were under the allowable limits projected for 2010. 7 refs., 1 tab., 6 figs., 6 appendices.

  19. Locked on course: Hydro-Quebec's commitment to mega-projects

    Maxwell, J.; Briscoe, F.; Suzuki, Tatsujiro; Lee, J.; Stewart, A.

    1997-01-01

    Large organizations often escalate their commitments to mega-project development, even after evidence becomes available of adverse environmental consequences or lack of economic feasibility. This escalation of commitment transcends both sectorial and national boundaries. Preeminent examples include controversial nuclear projects in the US, hydroelectric projects like the Three Gorges Dam in China, and transport projects like the Chunnel and the Concorde. In this article, the authors examine the experience of Hydro-Quebec with the Great Whale Project. They argue that Hydro-Quebec escalated its commitment even after serious questions emerged about its environmental impacts and economic feasibility, because of (1) its earlier success with large projects, (2) its engineering culture''s norms for consistency, and (3) its role in the government''s desire for economic and cultural autonomy. Finally, they discuss the changes that are necessary to break commitments to such projects

    1988-01-01

    Hydro-Quebec has created two management positions specifically for reservoirs, namely Reservoir Ecology Advisor and Reservoir Management Advisor. To assist management decisions, a means was required of bringing together all existing environmental information for each reservoir operated by Hydro-Quebec, including storage reservoirs, auxiliary reservoirs and forebays. A relational database using Reflex software was developed on a network of Macintosh computers. The database contains five blocks of information: general information, and physical, physiochemical, biologic and socioeconomic characteristics for each reservoir. Data will be collected on over 100 sites, and the tool will form the basis for developing a medium-range study program on reservoir ecology. The program must take into account the physical, biological and socioeconomic aspects of the environment, as well as the concerns of management personnel operating the reservoirs, the local population, reservoir users, and various government departments. 2 figs

    Morton-Chang et al. highlighted in their article the key strategic pillars of a community-based dementia care strategy: put "people first," support informal caregiving and enable "ground up" innovation and change. In our commentary, we draw upon our experience as authors of the Quebec Alzheimer Plan and evaluators of its implementation by the Quebec Ministry of Health and Social Services (MSSS). To us, a sustainable dementia care strategy entails a patient-centred approach, grounded in primary care, caring for persons with dementia at every stage of the disease. Implementation of such a strategy requires an ongoing effort to allow innovation adoption by clinicians and organizations.

    A method developed by Hydro-Quebec for establishing the short-term capacity margin requirements for dealing with uncertainties from 1 to 24 hours in advance, was presented. Hydro-Quebec's generating system and characterization of the problems associated with meeting load requirements were discussed. Factors accounted for included those concerning internal load forecast, unit forced outages, risks of not meeting firm load, risks of not meeting real-time reserves requirements, costs, time delays, and operating constraints of non-hydraulic resources. Each of these were described in detail, and methods for combining mathematical uncertainties were presented. Procedures used for selecting an appropriate risk level and building a margin policy were described. Improvements for more accurate modelling were discussed. 5 refs., 2 tabs., 5 figs

    2015-01-01

    The author is the witness of a historic period of the psychiatry in the province of Quebec in Canada, widely francophone. He describes the context, the training in psychiatry, and the care. In Quebec, in the 1950s, the psychiatry did not exist as such as speciality. There was however a discipline: the neuropsychiatry. It was managed by the neurologists who agreed to take care of cases of psychiatry, which few doctors wanted to treat at this moment. The religious and rural society in Quebec of the 1950s got ready for the "Revolution tranquille". The latter finally burst after 1960. But the artistic environment was already in full excitement, and from 1948, it showed its opposition to the values which were current with the publication of the Refus global. Among the signatories of the latter, we find Bruno Cormier as medical student who will become, after 1950, a psychiatrist and a psychoanalyst. To become a psychiatrist, it was necessary to be trained as an intern in a residency program in the USA, UK or in France. The residency in the United States in the 1950s represented a great adventure for the young doctors of Quebec, especially for the French speakers. At the end of 1950s, the pharmacology emerged. However, he described his own experience as an observer or an actor with ECT, Sakel cure and about the lobotomy.

    The high rate of youth suicide in some First Nations villages of Northern Quebec is an important public health problem. Based on a six-year field study in three villages belonging to the Atikamekw and Anishinabe groups, this paper proposes changes in three areas of social policy that could contribute to prevention of youth suicide. These three areas are: youth protection, administration of justice, and housing. An argument is made first to adapt the youth protection law of Quebec and to give greater responsibility to communities in individual cases in order to prevent child placement outside the villages. Regarding the administration of justice, we suggest initiatives to encourage rapid prosecution of crimes on reserves and the adoption of an approach based on reconciliation between perpetrator and victim. Finally, we indicate how housing measures could help safeguard children's wellbeing given that overcrowding can contribute to suicide. The discussion also proposes that these three key changes in social policy could be relevant in other Aboriginal communities both within and outside of Quebec. Copyright © 2013 Elsevier Ltd.

    Many women are exposed to medications during pregnancy. The Quebec Pregnancy Cohort (QPC) is a prospective population-based cohort which includes all data on pregnancies and children between January 1997 and December 2008. We linked four administrative databases in Quebec, Canada: RAMQ (medical and pharmaceutical), MED-ECHO (hospitalizations), ISQ (births/deaths), and MELS (Ministry of Education). Pregnancies included were covered by the Quebec prescription drug insurance plan (36% of women aged 15-45 years) from 12 months prior until the end of pregnancy. We analyzed 97,680 pregnancies. Prevalence of medication use was 74% pre-pregnancy, 56% during pregnancy, and 80% post-pregnancy. Most frequently used medications during pregnancy were antibiotics (47%), antiemetic drugs (23%), and non-steroïdal anti-inflammatory drugs (NSAIDs) [17%]. Medication users were more likely to have spontaneous abortions, preterm births, children with congenital malformations and postpartum depression than non-users (ppregnancy.

    Quebec's new contaminated site policy sets out a broad new set of requirements with which industry will have to comply. The new policy entitled 'Politique de protection des sols et de rehabilitation des terrains contamines' is much more comprehensive and detailed than its 1988 predecessor and contains many new elements. The policy seeks to maintain soil and groundwater quality criteria and focuses on the protection of clean commercial and industrial sites through pollution prevention actions. It also takes into account progress which has been made since the inventory of contaminated sites across Quebec. It considers the characteristics of each site and the problems posed by ongoing disposal of contaminated soils in landfills and advances in treatment technologies. The issue of who is responsible for contaminated sites is addressed and the requirements for responsible parties are described in detail. Risk assessment was also introduced as a tool for remediation planning in some cases. The new policy stresses prevention, and attempts to clearly outline site characterization and remediation duties for new and existing industries that pose potential risk of soil and groundwater contamination. 2 tabs., 2 figs

    In 1986 Hydro-Quebec set a province-wide objective, under its program to improve the quality of customer service, to achieve 95% billing based on real readings. Using market studies, Hydro-Quebec was able to determine a population (approximately 10% of customers) of hard-to-access meters. To reach the objective, they examined the options of using additional human resources or using new technology. In 1988, they decided to adopt inbound technology (TELEREADER) and carry out a pilot project to validate certain aspects of the technology. This document gives an introduction to TELEREADER, along with its requirements, parameters and information on its installation.

    A study was conducted to establish the sensitivity of the average price of electricity in the domestic Quebec market with respect to the volume of electricity exported. Economic data are presented on electricity in relation to other forms of energy in the northwest North American continental framework. The state of electricity exports and the hydroelectric potential of Quebec with respect to the capacity of neighboring networks to utilize this potential are discussed. CANREM (Canadian Regionalized Electricity Model) is described and used to simulate the effect of electric power exports on the Quebec electricity price over a 23-year period starting in 1987. Three simulation scenarios are presented and analyzed. The results obtained indicate a significant increase in the domestic price during the time that generation and transmission installation is being carried out. In contrast, during the years when service is offered, the slowing of the increase in the price of electricity is the determining factor with regard to the net social gain which can be achieved over the long term for Quebec society. 75 refs., 10 figs., 18 tabs

    Lymphogranuloma venereum (LGV) is a sexually transmitted infection (STI) caused by Chlamydia trachomatis genotypes L 1 , L 2 and L 3 . This LGV is associated with significant morbidity and increased risk of HIV transmission. While fewer than two cases per year were reported in Quebec before 2005, LGV emerged in 2005-2006 with 69 cases, followed by a period of low incidence (2007-2012), and subsequent re-emergence since 2013. To describe the incidence of LGV in Quebec and the characteristics of the affected population, including demographics and risk factors, clinical manifestations, laboratory tests, treatments and reinfection rates. Descriptive data were collected from the notifiable diseases records through the Institut national de santé publique du Québec (INSPQ) infocentre portal. Questionnaires were obtained through the enhanced surveillance system and transmitted anonymously to the Quebec Ministry of Health. In-depth analysis was performed on cases from 2013 to 2016. There were 338 cases of LGV over the four-year period in Quebec. All cases were male, excluding one transsexual. Mean age was 41 years. Most lived in Montréal (81%) and were men who have sex with men (MSM; 99%). The majority (83%) reported four sexual partners or more in the last year, met mostly through the Internet (77%) and in saunas (73%). Frequency of sexual intercourse with out-of-province residents decreased in 2013-2016 (27%) compared with 2005-2012 (38%). History of STIs was frequent: 83% were HIV-infected, 81% reported previous syphilis and 78% previous gonorrhea. Recreational drug use was frequent (57%), reaching 71% in 2016. Most cases were symptomatic, a proportion which decreased in 2016 (68%) compared with 2013-2015 (82%; p =0.006). Clinical presentations included proctitis (86%), lymphadenopathy (13%) and ulcer/papule (12%). Reinfections, mostly within two years of first infection, occurred in 35 individuals (10%). Conclusion: The re-emergence of LGV in Quebec involves an urban

    Full Text Available Cree births in Quebec are characterized by the highest reported prevalence of macrosomia (~35% in the world. It is unclear whether Cree births are at greater elevated risk of perinatal and infant mortality than other First Nations relative to non-Aboriginal births in Quebec, and if macrosomia may be related.This was a population-based retrospective birth cohort study using the linked birth-infant death database for singleton births to mothers from Cree (n = 5,340, other First Nations (n = 10,810 and non-Aboriginal (n = 229,960 communities in Quebec, 1996-2010. Community type was ascertained by residential postal code and municipality name. The primary outcomes were perinatal and infant mortality.Macrosomia (birth weight for gestational age >90th percentile was substantially more frequent in Cree (38.0% and other First Nations (21.9% vs non-Aboriginal (9.4% communities.

    2010-01-01

    NB Power was faced with major financial and technical challenges in generation that would lead to significant rate increases over several years to come. In 2009, the governments of New Brunswick and Quebec proposed an agreement whereby Hydro-Quebec would acquire most of the assets of NB Power and provide a guaranteed electricity supply at a set price to the province. The proposal involved the sale of NB Power's hydro generation facilities, 2 diesel peaking plants and the Point Lepreau nuclear generating facility. It also included a guaranteed bulk electricity supply of 14 Terawatt-hours per year by Hydro-Quebec at a blended rate of 7.35 cents per kilowatt-hour. The new Brunswick government would retain ownership of the fossil-fuelled power plants, the NB Power transmission assets and the NB Power distribution assets and customer sales. A 6-person independent panel was asked to examine the proposal. This report addresses the proposed agreement as presented to the Panel up to January 26, 2010. The panel conducted an independent and objective examination of the financial implications; long-term effects on electricity rates; New Brunswick's control of energy policies; environmental impacts; short-and long-term risks and avoided risks; and benefits and costs to the provincial economy. The Panel drew its conclusions and recommendations on the basis of available information. The Panel concluded that the benefits to New Brunswick contribute to real and positive value to New Brunswick over business as usual. tabs., figs.

    2007-01-01

    A municipal waste incinerator near Lower Town Quebec has been identified as a major source of air pollution, notably emissions of dioxins, furans, nitrogen oxides (NOx), volatile organic matter (VOC) and polycyclic aromatic hydrocarbons (PAH). Combustion fumes contain gases such as carbon monoxide (CO), carbon dioxide (CO 2 ) and sulphur dioxide (SO 2 ), as well as dusts, fly ash and particulate matter that is easily airborne. The risks associated with poor air quality have been evaluated along with the effects of pollutants on young children, pregnant women, senior citizens and those with cardiac problems. Some studies have reported that exposure to NOx may cause lung cancer and certain VOCs can irritate the respiratory tract system. Air quality tests have also revealed the presence of mercury. In combination, all these pollutants create smog. The concrete actions that have been taken to address smog issues were discussed. The distance between the incinerator and different residential areas within Lower Town Quebec have been measured along with air quality. Health risks were found to be higher in areas closer to the incinerator. Major modifications have been recommended in order to reduce pollution emissions from the incinerator. These include modernizing the equipment, installing proper scrubbers, and to ultimately the close the incinerator if it continues to underperform. refs., tabs., figs

  19. 735 kV air-blast circuit breakers for Hydro Quebec

    Energy Technology Data Exchange (ETDEWEB)

    Lindstrom, I

    1966-01-01

    In 1962 the Quebec Hydro-Electric Commission started the development of aproject for utilizing water power in Manicouagan and Outardes, two rivers some 350 miles northeast of the city of Montreal on the left bank of the St. Lawrence estuary. The project involved the transmission of power at 735 kV ac from Manicouagan and Outardes to the heavy and growing load centers of Quebec and Montreal. The total amount of energy to be transmitted in the final stage is about 6,000 MW. The project involved the need of considerable quantities of apparatus for 735 kV, such as transformers, reactors, lightning arrestors, circuit-breakers, and disconnectors. Since the supply of the major part of the 735 kV circuit-breakers, altogether 14 three-pole units, was awarded to ASEA in Sweden, a short presentation of these airblast circuit-breakers is presented.

    1994-01-01

    Full Text Available Q fever, a zoonosis acquired by inhalation of the rickettsia Coxiella burnetii, is rarely diagnosed in Canada. The world incidence has been increasing since 1960, because of progressive dissemination of this microorganism in animal populations, particularly domestic ruminants. Some recent outbreaks were caused by cats. Of 14 cases reported in Quebec between 1989 and the beginning of 1993, nine occurred successively in an 18-month period in the rural region surrounding Trois-Rivières, after contact with livestock or cats. These cases are reported here, with the results of serological screening of the workers of an abattoir where one of the cases worked. Five additional cases reported in Quebec during the same period are briefly reviewed.

  1. Public participation in strategic environmental assessment (SEA): Critical review and the Quebec (Canada) approach

    Gauthier, Mario; Simard, Louis; Waaub, Jean-Philippe

    2011-01-01

    It is widely accepted that public participation must be a part of strategic environmental assessment (SEA) procedures, and yet few studies have been conducted on the implementation of SEA public participation procedures. Accordingly, the theoretical and practical aspects of public participation in SEA remain research priorities for environmental policy-making. This paper presents a review of the Quebec (Canada) model of public participation in SEA through an evaluation of six public hearings on proposed directions and policies concerning, respectively, hazardous waste, forest protection, residual materials, energy, water management and pig farming. First, the authors examine the theoretical dimensions of SEA and public participation in the process. Second, they give a summary of the lessons that can be learned from the few Canadian and international experiences. Third, they outline the Quebec experience. Finally, they conclude by evaluating the opportunities and limitations of the Quebec experience and make some recommendations to improve its application.

    OBJECTIVES: We sought evidence to support the hypothesis that advancing maternal age is potentially causing a rise in preterm birth (PTB) rates in high-income countries. METHODS: We assessed maternal age-specific trends in PTB using all singleton live births in Denmark (n = 1 674 308) and Quebec (n...... = 2 291 253) from 1981 to 2008. We decomposed the country-specific contributions of age-specific PTB rates and maternal age distribution to overall PTB rates over time. RESULTS: PTB rates increased from 4.4% to 5.0% in Denmark and from 5.1% to 6.0% in Quebec. Rates increased the most in women aged 20...... to 29 years, whereas rates decreased or remained stable in women aged 35 years and older. The overall increase over time was driven by age-specific PTB rates, although the contribution of younger women was countered by fewer births at this age in both Denmark and Quebec. CONCLUSIONS: PTB rates increased...

    A 3-bp deletion (ΔF508) in the cystic fibrosis (CF) gene is the mutation on the majority of CF chromosomes. We studied 112 CF families from North American populations of French ancestry: French-Canadian families referred from hospitals in three cities in Quebec and from the Saguenay-Lac St. Jean region of northeastern Quebec and Acadian families living in Louisiana. ΔF508 was present on 71%, 55%, and 70% of the CF chromosomes from the major-urban Quebec, Saguenay-Lac St. Jean, and Louisiana Acadian families, respectively. A weighted estimate of the proportion of ΔF508 in the French-Canadian patient population of Quebec was 70%. We found that 95% of the CF chromosomes with ΔF508 had D7S23 haplotype B, the most frequent haplotype on CF chromosomes. In the Saguenay-Lac St. Jean families, 86% of the CF chromosomes without ΔF508 had the B haplotype, compared with 31% for the major-urban Quebec and Louisiana Acadian families. The incidence of CF in the Saguenay-Lac St. Jean population was 1/895 live-born infants. PMID:2220803

    2006-06-15

    In response to growing energy demands, Quebec has proposed the construction of 3 deep water terminals to accommodate methane tankers which transport liquefied natural gas (LNG). This paper focused on the proposed Gros Cacouna Port project in the St. Lawrence Seaway which is currently under study and subject to approval. Equiterre, questioned the energy security aspect of the proposal and argued that increasing Quebec's reliance on increasingly expensive energy would decrease energy security. In addition, importation of LNG would bring a clear exit of capital outside the province. Equiterre also argued that reliance on fossil fuels should be decreased in order to mitigate greenhouse gas emissions which contribute to climate change. The organization questioned whether the economic and social need for the proposed project justifies a greater dependency on fossil fuels and the associated impact on the environment and fragile ecosystems of the St. Lawrence. It was suggested that alternative solutions such as renewable energy sources and energy efficiency should be explored in order to promote sustainable development, increase energy security and reduce greenhouse gases. Equiterre argued that Quebec can and must decrease, and even eliminate, its dependence on fossil fuels, including natural gas, for Quebec's economic, social and environmental well-being. For these reasons, Equiterre recommended that the proposed project be rejected, particularly since the project proponents failed to show the real impact that the project would have on Quebec markets. 72 refs., 10 tabs., 21 figs.

    2011-01-01

    Worldwide electricity sector reforms open up electricity markets and increase trades. This has environmental consequences as exports and imports either increase or decrease local production and consequently greenhouse gas (GHG) emissions. This paper's objective is to illustrate the importance of electricity trade's impact on GHG emissions by providing an estimate of the net GHG emissions resulting from these trades. To achieve this objective, Quebec hourly electricity exchanges with adjacent jurisdictions were examined over the 2006-2008 period. In order to associate a specific GHG emission quantity to electricity trades, hourly marginal electricity production technologies were identified and validated using the Ontario hourly output per power plant and information released in the Quebec adjacent system operator reports. It is estimated that over three years, imports into Quebec were responsible for 7.7 Mt of GHG, while Quebec hydropower exports avoided 28.3 Mt of GHG emissions. Hence, the net result is 20.6 Mt of avoided emissions over 2006-2008, or about 7 Mt per year, which corresponds to more than 8% of the Quebec yearly GHG emissions. When GHG emissions from all life cycle stages (resource extraction to end-of-life) are accounted for, the net avoided GHG emissions increase by 35%, to 27.9 Mt. - Research highlights: → Environmental benefits of hydropower exports are considerable. → Detailed GHG assessment of such electricity trade is missing from the literature. → Net GHG emissions estimate resulting from such trade is provided. → GHG gains are significant in the Northeast American electricity market due to such electricity trade.

  8. Energy efficiency at Hydro-Quebec: Why forget the substitution of electricity by natural gas?

    International Nuclear Information System (INIS)

    Bernard, J.-T.

    1994-01-01

    Hydro-Quebec has launched an energy program which will cost $1.9 billion and which intends to save 9.3 TWh of electricity consumption by the year 2000, equivalent to 5.6% of the forecasted electricity consumption. The program only considers electricity and ignores other energy sources. An analysis is conducted to determine whether the subsidies that Hydro-Quebec is prepared to spend in each sector of the program would be sufficient to make up the difference between the cost of electricity and that of natural gas for the end-user. A positive response to this question will allow identification of a less costly way that Hydro-Quebec could realize its energy efficiency objectives. The analysis takes into account the marginal cost of electricity production, the average cost of energy efficiency measures, electricity prices, and the prices of natural gas and of gas-burning equipment. The results of a detailed analysis of four typical cases in the residential and commercial sectors indicate that market segments exist in which an energy efficiency program that includes substitution of other forms of energy for electricity would be preferable to a simple reduction in electricity consumption. However, the rationale for the Hydro-Quebec program is that electricity prices are based on historical average costs; as a result, electricity prices are lower than marginal costs. This problem should be addressed before considering expensive energy efficiency programs where the least-cost alternative is not even considered. 5 refs., 1 fig., 2 tabs

    Previous literature has suggested that laws and regulations may impact the use of palliative sedation. Our present study compares the attitudes of French-speaking physicians practicing in the Quebec and Swiss environments, where different laws are in place regarding physician-assisted suicide. Data were drawn from two prior studies, one by Blondeau and colleagues and another by Beauverd and coworkers, employing the same two-by-two experimental design with length of prognosis and type of suffering as independent variables. Both the effect of these variables and the effect of their interaction on Swiss and Quebec physicians' attitudes toward sedation were compared. The written comments of respondents were submitted to a qualitative content analysis and summarized in a comparative perspective. The analysis of variance showed that only the type of suffering had an effect on physicians' attitudes toward sedation. The results of the Wilcoxon test indicated that the attitudes of physicians from Quebec and Switzerland tended to be different for two vignettes: long-term prognosis with existential suffering (p = 0.0577) and short-term prognosis with physical suffering (p = 0.0914). In both cases, the Swiss physicians were less prone to palliative sedation. The attitudes of physicians from Quebec and Switzerland toward palliative sedation, particularly regarding prognosis and type of suffering, seem similar. However, the results suggest that physicians from Quebec could be slightly more open to palliative sedation, even though most were not in favor of this practice as an answer to end-of-life existential suffering.

    We report the results of a cancer pain survey mailed to Quebec hematologist-oncologists and palliative care physicians in 1999. The survey was designed to sample views on the current status of pain management and on obstacles to the provision of adequate pain relief for patients. The survey, formulated by an ethics network centered at the Clinical Research Institute of Montreal, was distributed to all members of the Association of Hematologist-Oncologists of Quebec and to all physician members of the Quebec Palliative Care Association. Responses were obtained from 138 Palliative Care Association members (response rate 61%) and 76 hematologist-oncologists (response rate 45%). Major obstacles reported included inadequate assessment of both contributory psychosocial issues and severity of pain, patient reluctance to take opioids, and inadequate access to non-drug techniques for pain relief. Access to opioids was not regarded as a problem. Both groups felt generally competent in their ability to manage various aspects of cancer pain therapy. They gave little credit to their formal medical school or residency training. Fifty-six percent of the palliative care group and 57% of the hemato-oncologists rated their medical school experience as only "poor" or "fair" on a 4-point scale. Residency ratings were modestly better. We conclude that medical faculties should assign a high priority to teaching health professionals patient assessment techniques. Simple symptom assessment scales should be routinely used in oncology/palliative care practice. Medical school training in pain management is not highly regarded and should be enhanced. We also note that, based on response to the scenario of a patient presenting with severe pain, many physicians, while feeling competent in the use of opioids, may be overly conservative in their initial use.

    To transculturally adapt the Quebec Back Pain Disability Scale for Hindi-speaking population and examine its psychometric properties in patients with low back pain. The Quebec Back Pain Disability Scale was translated and cross-culturally adapted into Hindi following international guidelines. Hindi version of the scale was completed by 120 patients with low back pain and 60 healthy controls. Patients with low back pain were also administered the Hindi-Roland Morris Disability Questionnaire and Visual Analog Scale. Psychometric evaluation included test-retest reliability, convergent and discriminative validity. Exploratory factor analysis was carried out to determine the factor structure. The factorial analysis revealed a four-factor solution (bending/carrying, ambulation/reach, prolonged postures and rest). Convergent validity was confirmed by high correlation of Hindi Quebec Back Pain Disability Scale to the Hindi version of Roland Morris Disability Questionnaire (r = 0.77 and p Visual Analog Scale (r = 0.682 and p Disability Scale has good test-retest reliability, discriminative and convergent validity and is appropriate for clinical and research use in Hindi-speaking low back pain patients. Implications for rehabilitation Linguistically and culturally adapted questionnaires help researchers make adequate inferences about instruments measuring health and quality of life. The translated version would serve as a valid research tool allowing comparability of data across cultures thus, providing opportunities for large multicenter, multicountry trials. A Hindi Quebec Back Pain Disability Scale version will help to improve the quality and efficacy of assessment of low back pain by developing in patients, a better understanding of the items which can be easily correlated with the activities of daily living.

    We assess how different scenarios of cardiovascular disease (CVD) prevention, aimed at meeting targets set by the World Health Organization (WHO) for 2025), may impact healthcare spending in Quebec, Canada over the 2050 horizon. We provide long-term forecasts of healthcare use and costs at the Quebec population level using a novel dynamic microsimulation model. Using both survey and administrative data, we simulate the evolution of the Quebec population's health status until death, through a series of dynamic transitions that accounts for social and demographic characteristics associated with CVD risk factors. A 25% reduction in CVD mortality between 2012 and 2025 achieved through decreased incidence could contain the pace of healthcare cost growth towards 2050 by nearly 7 percentage points for consultations with a physician, and by almost 9 percentage points for hospitalizations. Over the 2012-2050 period, the present value of cost savings is projected to amount to C$13.1 billion in 2012 dollars. The years of life saved due to improved life expectancy could be worth another C$38.2 billion. Addressing CVD mortality directly instead would bring about higher healthcare costs, but would generate more value in terms of years of life saved, at C$69.6 billion.

    1993-01-01

    Full Text Available Twenty-three cases of blastomycosis were reported in a survey conducted in the province of Quebec from 1981–90. Thirteen patients resided south of the St Lawrence River and the other 10, north. Two small geographical clusters were apparent in and around the cities of Sherbrooke and Quebec. The male to female ratio was 1.6:1 and the median age was 47 years (range 26 to 77. Lung involvement was observed in 19 cases and was the only site involved in 11. Cutaneous manifestations were reported in 11 cases while bone infection (three cases and central nervous system (CNS infections were also noted. Diagnosis was confirmed by culture in 21 cases and by histopathology in two cases. Of the 21 culture-positive cases, 12 strains of Blastomyces dermatitidis were isolated from lungs, nine from skin, and one each from bone and brain. Serodiagnostic tests by immunodiffusion or complement fixation were positive for only one of the 10 patients known to have been tested. Ten patients were treated with amphotericin B, 11 with ketoconazole, one with fluconazole and eight underwent surgery. While amphotericin B was used in eight of the 10 earliest treated cases, ketoconazole was administered in 10 of the 13 more recent cases. Of the patients for whom follow-up data have been obtained, 21 are reported cured (one of whom was not treated and one patient died of another cause. This survey confirms that blastomycosis is a rare disease in this endemic area and that patterns of therapy are changing.

  20. Shunning the Bird's Eye View: General Science in the Schools of Ontario and Quebec

    Hoffman, Michelle

    2013-04-01

    This paper considers the adoption of general science courses in two Canadian provinces, Ontario and Quebec, during the 1930s. In Ontario, a few science teachers had followed the early general science movements in the United States and Britain with interest. During the 1930s, several developments made the cross-disciplinary, applied thrust of general science particularly appealing to Ontario educationists. These developments included a new demand for vocational education, renewed reservations about pedagogical rationales based on transfer of training, and a growing professional divide between high school science teachers and university scientists. Around the same time, scientists in the Quebec's French-language universities were engaged in a concerted campaign to expand the place of science in the province's francophone secondary schools. The province's prestigious classical colleges, which were the scientists' principal target for reform, privileged an inductive view of science that had little in common with the applied, cross-disciplinary emphasis of the general science courses gaining support in English-speaking school systems. In 1934, however, a popular American general science textbook was adopted in a workers' cooperative devoted to adult education. Comparing the fate of general science within these two education systems draws attention to the fact that general science made inroads in francophone Quebec but had little influence in public and private schools. In light of the growing support general science enjoyed elsewhere, we are led to explore why general science met with little overt interest by Quebec scientists pushing for school science reform during the 1930s.

  1. Total mercury and methylmercury fluxes via emerging insects in recently flooded hydroelectric reservoirs and a natural lake

    1998-01-01

    Total mercury (total Hg) concentrations in emerging aquatic insects ranged from 140 to 1500 ng g -1 dry wt. in two hydroelectric reservoirs of northern Quebec compared with 50-160 ng g -1 dry wt. in a natural lake. Methylmercury (MeHg) concentrations were somewhat lower, ranging from 35 to 800 ng Hg g -1 dry wt. in reservoirs and from 29 to 90 ng g -1 dry wt. in the natural lake. Contamination of insect taxa of reservoirs was on average 2-3 times higher than their counterparts in the natural lake. There was no difference between total Hg and MeHg concentrations of insects sampled from flooded forest soils and flooded peatland, although total Hg and MeHg concentrations differed between flooded peatland and flooded forest soils themselves. Insect biomasses were approx. two times higher in the reservoirs than in the natural lake (580-2200 mg m -2 year -1 dry wt., 950 mg m -2 year -1 dry wt., respectively); chironomids dominated in the reservoirs and trichopterans dominated in the natural lake. Similarly, total MeHg fluxes via emerging insects were approx. 2-4 times higher in reservoirs than that of the natural lake (55-224 ng MeHg m -2 year -1 dry wt., 74 ng MeHg m -2 year -1 dry wt., respectively). Our results show the importance of the insect community in the transfer of MeHg from flooded soils and flooded peatlands to fish, and that this pathway probably makes a significant contribution to the rapid rise of Hg levels in the fish community after flooding

  2. Economical and technical origins of the electricity sector nationalization in Quebec: the mixed regime experience, from 1944 to 1963

    Bellavance, Claude

    2003-01-01

    For almost twenty years (1944-1963), private and public firms coexisted in the electricity sector in Quebec. We would like, in this article, to relate the growth of a state company (Hydro-Quebec) to the decline of the private sector, the networks' interconnection, and the confirmation of the hydraulic channel as the quasi unique source of primary energy for electricity production in that province. We will also check whether the mixed regime really was a case of 'yardstick competition' or not. Finally, we will examine the accuracy of the 'natural monopoly' concept as applied to the evolution of the electricity sector in Quebec before the second nationalization in 1963

  3. Rate proposal for 1993 and 1994 [Hydro-Quebec

    International Nuclear Information System (INIS)

    1994-01-01

    In its development plan, Hydro-Quebec has the goal of aligning its average rate increases with the inflation rate over the period 1993-2000. The near- and long-term evolution of rates must also follow the evolution of the costs of supply and assure the financial stability of the utility. The average annual increase target prices for 1993-95 is 3.5%. In 1993, the increase in supply cost is attributable to startup of service from the LaGrande 2-A and Becancour stations, as well as to energy efficiency programs and improvements in quality of service. In 1994-95, supply cost increases are related mainly to the second phase of the LaGrande complex. The present rate proposal is for two years and assures that rates will not increase beyond the projected rates of inflation of 2.3% for 1993 and 2.7% for 1994. Hydro-Quebec also has a long-term objective of gradually reducing cross-subsidization that exists among different tariff categories. A slight differentiation of rate increases in the various categories is proposed to reduce this cross-subsidization. The proposed rate increases are expected to bring additional revenues of $152 million for 1993/94 and $186 million for 1994/95. 3 figs., 35 tabs

    Hydraulic resources currently account for more than 95 per cent of Hydro-Quebec's generation capacity. Hydro-Quebec also plans to purchase more wind power in the future. However, the utility wind and hydroelectric resources will be affected by climatic change in the future. This paper outlined research needed by hydroelectric and water resource managers in order to accurately determine the impacts of climatic change. Parameters included changes in annual and seasonal distribution as well as changes in the variability of natural inflows. The research will be used to determine the configuration of new projects as well as the refurbishment and replacement of existing infrastructure. Load profiles for the future indicate that electricity use will change, with less heating needed in winter, and more air conditioning required in summer months. The Delta method was used to determine impacts of future inflows and hydrological regimes. A case study of climate change impacts and management strategies for the Outardes River system up to the year 2050 was presented. The study showed that higher inflows are expected to produce more energy. Maintenance planning and flood control techniques were also discussed. The study showed that the effects of climate change on each of Hydro-Quebec's systems is expected to follow a similar pattern to the Outardes system. tabs., figs

    The prevalence of musculoskeletal disorders is high and expected to increase in the next decade. Persons suffering from musculoskeletal disorders benefit from early physiotherapy services. However, access to publicly funded physiotherapy services has been shown to be compromised by long waiting times and limited availability of resources in many countries around the world. Decisions on resource allocation may create geographic disparities in provision and access to services, which may result in inequity in access. This study aimed to assess variations in demand and provision of publicly funded outpatient physiotherapy services across the province of Quebec, Canada, as well as to assess the demand to provision relationship. We conducted a secondary analysis of data retrieved from the 2008 Quebec Health Survey and data obtained from a survey of hospitals in the province of Quebec in 2015. We used geographic information systems analyses and descriptive analyses to assess geographic variations and the relationship between demand and provision. Our results indicate substantial variations in the provision and demand for physiotherapy services in the province of Quebec. The variations in service provision did not follow the variations in demand. Long waiting times and insufficient provision of services were found in many regions. The variations in provision of physiotherapy services between regions reported in our study did not correspond to the variations in demand. Such geographic variations and demand to provision mismatches may create inequity in access to services, especially for those unable to afford private services. © 2017 John Wiley & Sons, Ltd.

    This study examines the views of five university professors in the province of Quebec on recent trends and developments in health education, the relative importance of health education as a health promotion strategy, and future prospects. Interviews were conducted and the participants were asked to validate the findings. Despite minor differences, the participants were found to have similar views on health education. The interviews also pointed to a significant emphasis on recent developments in our understanding of the factors influencing health behaviors and the theoretical foundations underlying processes of change. However, much remains to be done to put this knowledge into practice. In Quebec, the field of health education has involved an increasingly diverse range of actors in recent years, although nurses continue to play an important role. Some feel that the emphasis on creating supportive environments for health and public policies has had a negative impact on the development of health education in Quebec. For others, we are witnessing the emergence of a more integrated system combining different health promotion strategies. In terms of future prospects, some remain pessimistic, emphasizing the potential effects of the current economic climate or the potential negative impact of the rise of therapeutic education, which may be at the expense of a more systemic approach. Others are more optimistic, arguing that the future of health education will be a matter of political will and that it will depend on the efforts of stakeholders to promote consistent and complementary measures.

  11. The Legal Framework for Groundwater Allocation in Quebec: Towards Integrated Water Management

    Directory of Open Access Journals (Sweden)

    Hugo Tremblay

    2008-09-01

    Full Text Available This paper aims at providing a model of the legal framework for groundwater allocation in the province of Quebec (Canada, identifying its potential deficiencies and suggesting possible improvements. In Quebec, groundwater is a res communis. The right to use it is tied to real estate property. This right forms the basis of the legal framework for the management of groundwater quantity. However, according to statutory law, the actual use of groundwater also depends on governmental authorisations that limit quantities used. The main statutory instrument for managing the resource is the Groundwater Catchment Regulation (GWCR, which aims at conflict prevention between first users and new users by means of governmental authorisations. In agricultural areas, an additional authorisation regime indirectly prioritises agricultural groundwater uses. Finally, legal mechanisms addressing conflicts between water users rely on the general litigation framework provided by Quebec law without establishing an order of priority for the different uses of the resource. According to Integrated Water Resources Management, four aspects of the legal framework for groundwater quantity management can be modified to increase the efficiency of the allocation regime: 1 provisions should be made to preserve a residual environmental flow; 2 an order of priority should be established between the different uses to minimise conflict; 3 the scope of the regime should be extended to all groundwater users to increase its efficiency; 4 stakeholders should participate in the management of the resource.

    Arenas, or skating rinks, represent a type of building with physical characteristics and uses which are relatively homogeneous throughout the country. This study revealed that the time is ripe to improve the energy efficiency of skating rinks in Quebec, and thereby gain environmental benefits through the more efficient use of refrigerants can cause damage to the environment. The aim of the study was to better define the technologies in use and the operating strategies and retrofitting techniques currently applied in the industry in order to provide guidance for an eventual Intervention Program in Refrigeration in Skating Rinks in Quebec. Background information was provided by the authors in section 1, followed by the mandate in section 2. The methodology used to carry out the study was described in section 3. The report examined four broad areas: the market, technical assistance, training, and partnerships. Each of these topics was reviewed in detail in section 4. A synthesis of the interventions was provided in section 5. The authors indicate that this project should be considered while Canada is attempting to meet its environmental commitments in the wake of increases in energy prices. Plans should be focused on measurable results within reasonable financial constraints. 13 figs.

    Climate change is a major issue facing Quebec's population and future generations. The scientific community generally agrees on the negative effects resulting from global climate change on human health, the environment and the economy. In 1997, the Kyoto Protocol was adopted by industrialized countries, whereby countries agreed to reduce their emissions of greenhouse gases (GHG) by a certain percentage, calculated from 1990 levels. In the case of Canada, this percentage was 6 per cent, for the first commitment period covering 2008-2012. Quebec's performance on the issue of GHG emissions compares favorably to that of other Canadian provinces, even to that of other industrialized countries. Canada ratified the Kyoto Protocol in December 2002. The Quebec National Assembly called for a parliamentary committee to meet on 18 February 2003 on the implementation of the Kyoto Protocol. Hydro-Quebec, since 1997, has favored the ratification of the Kyoto Protocol by the Canadian government. In this document, Hydro-Quebec makes its position known in the context of this debate and the commercial context of the electric power industry in 2003. The first section of the document was devoted to the favorable performance of Hydro-Quebec, on the retroactive and prospective aspects of GHG emissions with regard to the entire electric power industry in Canada. In the second section, an explanation was provided, in the context of deregulation of the electricity market in North America, on the implementation of the Kyoto Protocol in Quebec and in Canada and how it becomes a major commercial issue for Hydro-Quebec. The analysis was conducted in light of the mandate of Hydro-Quebec to provide a secure and reliable service to its customers. refs., 1 fig

    The paper presents the development of a comprehensive wind atlas of the Province of Quebec. This study differs from previous studies by 1) use of a standard classification index to categorize the wind resource, 2) extensive review of surface and upper air data available for the Province to define the wind resource, and 3) integration of available wind data with the topography of the Province. The wind resource in the Province of Quebec is classified using the scheme proposed by Battelle-Pacific Northwest Laboratory (PNL). The Battelle-PNL classification is a numerical one which includes rankings from Wind Power Class 1 (lowest) to Wind Power Class 7 (highest). Associated with each numerical classification is a range of wind power and associated mean wind speed at 10 m and 50 m above ground level. For this study, a classification for 30 m above ground level was interpolated and used. A significant amount of wind data was gathered for the Province. These data were obtained from Atmospheric Environment Service (AES), Canada, from wind project developers, and from climatological summaries of surface and upper air data. A total of 35 primary data sites were selected in the Province. Although a number of wind data sites in the Province were identified and used in the analysis, large areas of the Province lacked any specific wind information. The Province was divided into grid blocks having dimensions of 1/4 o latitude by 1/3 o longitude. Each grid block is assigned a numerical Wind Power Class value ranging from 1 to 7. This value is based on the integration of the available wind data and the topography within the square. The majority of the Province was classified as 1 or 2. Coastal locations and topographic features in the interior of the Province typically have Wind Power Class 3 or higher. (author)

    We sought evidence to support the hypothesis that advancing maternal age is potentially causing a rise in preterm birth (PTB) rates in high-income countries. We assessed maternal age-specific trends in PTB using all singleton live births in Denmark (n = 1 674 308) and Quebec (n = 2 291 253) from 1981 to 2008. We decomposed the country-specific contributions of age-specific PTB rates and maternal age distribution to overall PTB rates over time. PTB rates increased from 4.4% to 5.0% in Denmark and from 5.1% to 6.0% in Quebec. Rates increased the most in women aged 20 to 29 years, whereas rates decreased or remained stable in women aged 35 years and older. The overall increase over time was driven by age-specific PTB rates, although the contribution of younger women was countered by fewer births at this age in both Denmark and Quebec. PTB rates increased among women aged 20 to 29 years, but their contribution to the overall PTB rates was offset by older maternal age over time. Women aged 20 to 29 years should be targeted to reduce PTB rates, as potential for prevention may be greater in this age group.

    In 1994, public hearings were held in Quebec city concerning a 120 megawatt (MW) gas cogeneration project that was to be coupled with an already existing pulp and paper mill in the downtown area. Cogeneration plants are often described as highly beneficial from the point of view of local environment. It is well known that the burning of natural gas emits far less sulfur dioxide (SO{sub 2}) and particulate matters (PM) than the combustion of oil or coal. The proposed plant would use high pressure vapour from a nearby incinerator plant and natural gas to produce low pressure vapor for the paper mill industry as well as electricity. The cogeneration plant would allow the paper mill to stop burning heavy oil. By using natural gas instead of heavy oil, the new cogeneration-paper mill complex (CPC) is expected to reinforce the recent trend and willingness towards improving downtown air quality. On the other hand, the CPC would emit more CO{sub 2}, due to the production of additional electricity. According to the Rio de Janeiro Agreement ratified in 1988, Canada is committed to stabilize its greenhouse gas emissions by the year 2000. Nevertheless, the cogeneration file is a new option considered by the Quebec Provincial Governement in its last energy triennal plan. However, it must be specified that the Province of Quebec contributes to less than 15 % of the total Canadian CO{sub 2} production although it represents more than 25 % of its population. Furthermore the maximum production of electricity by this file has been set to 250 MW. It is a very small fraction of the total production of electricity in Quebec, which is 200 TW

    Full Text Available This article aims to reconstruct the history of civil society in Quebec (Canada to relate it with nationalism, the rise of the welfare state, trade unions, Catholic Church and civil society, the dynamic forces of society. Through in-depth interviews with key leaders, exploration of institutional archives and specific literature, we work with a particular case that, when compared to Catalonia, will allow us to evaluate the importance of civil society within nationalism. This actor is not usually considered as the central subject of researches and rarely token into account, unlike political parties, their leaders or intellectuals. Currently, in a context of crisis of the state and political parties, it has begun to be considered that civil society can be a key factor for its ability to produce alliances between sectors, build hegemony and dialogue directly with the population. The study is divided into four parts: 1 the development of the theoretical framework along with the construction of the object of study and the hypotheses; 2 an analysis about the importance of the involvement of civil society in the construction of the nationalist movement in Quebec; 3 a comparison with the Catalan case; and, 4 finally some conclusions.

    Full Text Available Rainbow trout is an exotic fish species that has been introduced in Quebec (Canada since 1893–1894. Despite spatially-restricted stocking for recreational fishing, the species has spread throughout the Saint Lawrence River. In this study, the relationship between rainbow trout occurrence (presence or absence and abiotic variables (river geomorphology and climate was examined for 91 coastal rivers throughout Eastern Quebec in order to determine which variables promote or impede the ongoing invasion process. Results revealed that rainbow trout presence in Eastern Quebec was primarily determined by geomorphological parameters. The invader’s presence was strongly related to the presence of tributaries (especially larger ones. To a lesser extent, the presence of rainbow trout was positively related to warm spring and summer temperatures and negatively related to the peak flood date occurring during the egg deposition period (May. This study proposes a parsimonious modelling approach to identify which environmental parameters favour the spreading of an invader, even when a limited dataset is available due to the incomplete invasion process.

    This article addressed the growing social concern regarding the development of major wind power projects in Quebec, particularly in the Gaspe and Bas-Saint-Laurent regions. It focused on the subjective dimensions of public perception and social acceptance of projects and emphasized the importance of cognitive and policy planning for dealing with major wind energy projects. Residents in close proximity to development projects are concerned with the dynamics of regional development; the relationship between residents and developer; and social impacts. The development of wind power in Quebec is in full expansion to meet renewable energy criteria. Several wind turbine arrays are in operation throughout the province and much progress has been made in terms of learning experience. From 1995 to 2007 several public hearings were held to allow residents to express their views regarding the construction of wind turbine arrays, their aesthetics, noise, impact on vegetation, and geographical proximity to habitat. With time, change was seen in both the public perception of energy development and the way of acting on it through different phases of the project. 19 refs., 2 figs.

  8. Quebec's petrochemical industry: prospects and challenges: proceedings of the workshop

    International Nuclear Information System (INIS)

    1992-01-01

    A review of the present status of Quebec's petrochemical industry was presented, including an historical perspective of the development of the industry. In terms of economic importance, the petrochemical industry in the province of Quebec occupies fifth place and is primarily concentrated in the Montreal region. The industry peaked in 1976 with six producing refineries in east Montreal. At that time, Montreal represented the largest refining centre in Canada with a combined capacity of 600,000 barrels per year. Although four of these refineries have closed, the province remains an important centre particularly in the manufacturing of oil-derived plastic products. The objective of this workshop was to throw light on the challenges and the strategic economic potential of the Montreal region, to obtain the views of experienced industry insiders regarding the extent of changes that globalization of the industry has produced and the kind of conditions that would have to be created to ensure that the Montreal region can continue to compete in the global market place. Recent initiatives and investments by the Canadian Government in the petrochemical sector were also summarized. tabs., figs

    Using the results of a six month survey on the doses received by non-monitored hospital workers from diagnostic nuclear medicine patients (DNMP) in three hospitals and published statistics on Quebec's workers and hospitals, an evaluation of the radiological impact of DNMP has been calculated on the Quebec's population. In 1989, diagnostic nuclear medicine gave an average of 6.4 mSv/act or a total of 2,800 sv-man. The diagnostic nuclear medicine technologists' community received 0.4 Sv-man and the non-monitored hospital workers 1.7 Sv-man from the DNMP in the same year. (author)

  10. Short-term responses to watershed logging on biomass mercury and methylmercury accumulation by periphyton in boreal lakes

    Increased timber harvesting in the boreal regions of Quebec may have a significant impact on aquatic ecosystems. Watershed disturbances such as logging increase chemical loading to lakes. Soil in the Canadian Shield readily adsorbs and accumulates mercury (Hg) from atmospheric deposition. Forest watersheds serve as large reservoirs of Hg that shed their metal load when soil and land hydrology are disrupted. This paper presented the results of a study evaluating the impact of logging on periphyton algal biomass and dry mass. The study also evaluated the impact of total mercury (THG) and methylmercury (MeHg) accumulation in the littoral zone of the boreal lakes. A before-after control-impact (BACI) sample design was applied that required data from control and target sites sampled both before and after the disturbances. The study was carried out on 18 boreal lakes located in the Grenville geological province. Eight lakes had their watersheds logged over 15 to 79 per cent of their area. A further 10 lakes were used as control sites to document interannual variations. The project used water quality and physiographic data acquired by research groups within the Sustainable Forest Management Network. Fourteen study lakes were sampled once a year during 2 consecutive ice-free seasons before and after logging, and another 4 lakes were sampled 2 years after logging. Significant decreases in algal biomass and increases in MeHg concentrations in periphyton mats in a majority of the harvested watershed lakes were detected. The increases may have a significant impact on organisms of higher trophic levels as they are at the base of the food web. Results suggested that the observed decrease in periphyton biomass combined with the increase in MeHg accumulation may magnify the impact of logging activities on fish and other aquatic predators. Two years after logging, it was observed that MeHg concentrations were still increasing. It was concluded that further research is needed

  11. Quebec mental health services networks: models and implementation

    Full Text Available Purpose: In the transformation of health care systems, the introduction of integrated service networks is considered to be one of the main solutions for enhancing efficiency. In the last few years, a wealth of literature has emerged on the topic of services integration. However, the question of how integrated service networks should be modelled to suit different implementation contexts has barely been touched. To fill that gap, this article presents four models for the organization of mental health integrated networks. Data sources: The proposed models are drawn from three recently published studies on mental health integrated services in the province of Quebec (Canada with the author as principal investigator. Description: Following an explanation of the concept of integrated service network and a description of the Quebec context for mental health networks, the models, applicable in all settings: rural, urban or semi-urban, and metropolitan, and summarized in four figures, are presented. Discussion and conclusion: To apply the models successfully, the necessity of rallying all the actors of a system, from the strategic, tactical and operational levels, according to the type of integration involved: functional/administrative, clinical and physician-system is highlighted. The importance of formalizing activities among organizations and actors in a network and reinforcing the governing mechanisms at the local level is also underlined. Finally, a number of integration strategies and key conditions of success to operationalize integrated service networks are suggested.

    Aim: To investigate current practice regarding clip placement after breast biopsy. Materials and methods: In June 2011, an online survey instrument was designed using an Internet-based survey site ( (www.surveymonkey.com)) to assess practices and opinions of breast radiologists regarding clip placement after breast biopsy. Radiologists were asked to give personal practice data, describe their current practice regarding clip deployment under stereotactic, ultrasonographic, and magnetic resonance imaging (MRI) guidance, and describe what steps are taken to ensure quality control with regards to clip deployment. Results: The response rate was 29.9% in France (131 respondents) and 46.7% in Quebec (50 respondents). The great majority of respondents used breast markers in their practice (92.1% in France and 96% in Quebec). In both countries, most reported deploying a clip after percutaneous biopsy under stereotactic or MRI guidance. Regarding clip deployment under ultrasonography, 38% of Quebec radiologists systematically placed a marker after each biopsy, whereas 30% of French radiologists never placed a marker in this situation, mainly due to its cost. Finally, 56.4% of radiologists in France and 54% in Quebec considered that their practice regarding clip deployment after breast percutaneous biopsy had changed in the last 5 years. Conclusion: There continues to be variations in the use of biopsy clips after imaging-guided biopsies, particularly with regards to sonographic techniques. These variations are likely to decrease over time, with the standardization of relatively new investigation protocols

  14. Can pelagic net heterotrophy account for carbon fluxes from eastern Canadian lakes?

    Dubois, Kristal; Carignan, Richard; Veizer, Jan

    2009-01-01

    Lakes worldwide are commonly oversaturated with CO 2 , however the source of this CO 2 oversaturation is not well understood. To examine the magnitude of the C flux to the atmosphere and determine if an excess of respiration (R) over gross primary production (GPP) is sufficient to account for this C flux, metabolic parameters and stable isotopes of dissolved O 2 and C were measured in 23 Quebec lakes. All of the lakes sampled were oversaturated with CO 2 over the sampling period, on average 221 ± 25%. However, little evidence was found to conclude that this CO 2 oversaturation was the result of an excess of pelagic R over GPP. In lakes Croche and a l'Ours, where CO 2 flux, R and GPP were measured weekly, the annual difference between pelagic GPP and R, or net primary production (NPP), was not sufficient to account for the size of the CO 2 flux to the atmosphere. In Lac Croche average annual NPP was 14.4 mg C m -2 d -1 while the average annual flux of CO 2 to the atmosphere was 34 mg C m -2 d -1 . In Lac a l'Ours average annual NPP was -9.1 mg C m -2 d -1 while the average annual flux of CO 2 to the atmosphere was 55 mg C m -2 d -1 . In all of the lakes sampled, O 2 saturation averaged 104.0 ± 1.7% during the ice-free season and the isotopic composition of dissolved O 2 (δ 18 O DO ) was 22.9 ± 0.3 per mille , lower than atmospheric values and indicative of net autotrophy. Carbon evasion was not a function of R, nor did the isotopic signature of dissolved CO 2 in the lakes present evidence of excess R over GPP. External inputs of C must therefore subsidize the lake to explain the continued CO 2 oversaturation. The isotopic composition of dissolved inorganic C (δ 13 C DIC ) indicates that the CO 2 oversaturation cannot be attributed to in situ aerobic respiration. δ 13 C DIC reveals a source of excess C enriched in 13 C, which may be accounted for by anaerobic sediment respiration or groundwater inputs followed by kinetic isotope fractionation during degassing

    Objective Juvenile delinquency is one of the major public concerns in many countries. This study aims to document the association between exposure to interparental violence and delinquent behaviors among high school students in Quebec (Canada). Methods A representative sample of 8194 students aged 14–20 years was recruited in Quebec (Canada) high schools. Participants completed a questionnaire describing delinquent behaviors as well as exposure to interparental psychological and physical violence. Findings Overall, one out of two participants has experienced delinquent behaviors and 61.8% of them have reported having been exposed to at least one of the two forms of family violence. Overall, youth exposed to interparental violence are more likely to experience delinquent behaviors. Both psychological and physical interparental violence were significantly and independently associated with delinquent behaviors. Conclusion The findings of this study point out the vulnerability of youth exposed to interparental violence. They also highlight the need in the prevention of juvenile delinquency to focus not only on youth but also on both parents that may have been involved in family violence. PMID:28111591

  16. Electricity/natural gas competition in Quebec

    1992-01-01

    The evolution of energy market shares (electricity, natural gas and oil products) in Quebec's residential and commercial sectors in the 1980s shows that energy source relative prices have influenced consumer behavior as expected. A set of comparisons from space and water heating markets in these sectors with regard to prices paid by consumers and costs incurred by society in general is presented. For the residential sector, it is seen that consumers pay only a fraction of the cost for electric space and water heating; the same service could be provided at smaller cost by natural gas. For the commercial sector, the electricity and natural gas tariffs convey the appropriate message with respect to the cost incurred in providing the service. 6 refs., 7 tabs

    This paper discusses results from a pilot study conducted in the spring of 2014 among young adults living in Montreal. The main objective of this study was to assess the relation between perception of the Charter of Quebec Values, 1 self-identification, perception of intercommunity relations, perceived discrimination, and psychological well-being in young students enrolled in undergraduate or graduate programs of a francophone university in Montreal. A total of 441 students (30.5% male, 69.5% female) took part in a web survey designed by the research team. The data analyses and results suggest that the debate around the Charter of Quebec values was associated with a shift from a predominantly positive perception of intercommunity relations to a predominantly negative one, particularly among women, immigrants, and those who self-identified as cultural or religious minorities. In addition, more than 30% of participants reported having experienced some form of ethnic or religious discrimination since the Charter was released (personally or as a witness). This was particularly the case among immigrants, as well as those who self-identified as bicultural or from cultural or religious minority groups. This study's results thus highlight the exacerbation of intercommunity tensions linked to the public debate around identity and intercommunity relations in Quebec. © The Author(s) 2016.

    Full Text Available Studies worldwide point toward increased risk of mental health issues among immigrants. Immigrants’ ability to integrate the cultural identity of their new country has been found to be a key factor in their psychological well-being. Even though researchers agree on the crucial role of identity integration in immigrants’ well-being, the current literature has two main limitations: 1 researchers do not agree on the importance that should be allocated to each of the cultural identities, and 2 research has focused on bicultural individuals as opposed to multicultural individuals. The present paper proposes to study Canadians immigrants living in the province of Quebec who, because of the political and linguistic situation of the province, face the challenge of integrating two new cultural identities (Quebecer and Canadian to their original one. Specifically, cluster analysis was used to observe identity profiles that naturally emerge among 120 Canadian immigrants from the province of Quebec. Identity profiles were then compared on various indices of well-being to identify the optimal identity structure. In total, four identity profiles emerged, differing in their levels of identity coherence (i.e., similar levels of identification with each group and identification to either the original group or the Quebecers. ANOVA results confirmed that identity profiles differed in their average level of well-being. First, immigrants with coherent profiles displayed higher levels of well-being. Second, among incoherent profiles, the profile where identification to the original group is the highest showed the greatest well-being. Implications suggest that in order to maximize immigrants’ well-being, psychologists should focus on the coherence between cultural groups as well as identification to the original group.

    This annual report for the Quebec electric utility presents an overview of the year's activities and its financial status, including export sales of electricity to New Brunswick, Ontario, New York State, and the New England states. Research programs and demonstration projects are described, as well as the utility's activities in Africa and Asia. Environmental and economic considerations for the province are presented. Financial data includes total sales, sales by sector, export sales, and rate changes. A financial statement is included. In 1991, public controversy arose over electricity exports, risk-and-profit sharing contracts with some industrial customers, and the impacts of hydroelectric development. A net income of $760 million was achieved, representing an 88.1% increase over the previous year when exceptional measures were required to offset cumulative years of low runoff. These measures were suspended in late 1990 but low 1991 precipitation forced the continued purchase of backup electricity. Energy efficiency programs resulted in savings equivalent to energy consumed by a town of 13,000 people. Exports accounted for 7.2% of total sales in 1991. The first three generating units of LaGrande-2-A, totalling 999 MW, were commissioned. The groundwork has been laid for the vast corporate strategy of total customer satisfaction entitled Defi performance. In 1991, annual interruption time per customer dropped to 5.32 hours. 5 figs., 5 tabs.

    Full Text Available Colorectal cancer is a leading cause of death and the third most common cancer in Canada. Evidence suggests that screening can reduce mortality rates and the cost effectiveness of a program compares favourably with initiatives for breast and cervical cancer. The objectives of the Association des gastro-entérologues du Québec Task Force were to determine the need for a policy on screening for colorectal cancer in Quebec, to evaluate the testing methods available and to propose one or more of these alternatives as part of a formal screening program, if indicated. Fecal occult blood testing (FOBT, endoscopy (including sigmoidoscopy and colonoscopy, barium enema and virtual colonoscopy were considered. Although most clinical efficacy data are available for FOBT and sigmoidoscopy, there are limitations to programs based on these strategies. FOBT has a high false positive rate and a low detection yield, and even a combination of these strategies will miss 24% of cancers. Colonoscopy is the best strategy to both detect and remove polyps and to diagnose colorectal cancer, with double contrast barium enema also being a sensitive detection method. The Task Force recommended the establishment, in Quebec, of a screening program with five- to 10-yearly double contrast barium enema or 10-yearly colonoscopy for individuals aged 50 years or older at low risk. The program should include outcome monitoring, public and professional education to increase awareness and promote compliance, and central coordination with other provincial programs. The program should be evaluated; specific billing codes for screening for colorectal cancer would help facilitate this. Formal feasibility, effectiveness and cost-effectiveness studies in Quebec are now warranted.

    Hydro-Quebec owns and operates more than 560 dams, including 200 dams that are classified as large dams. By 2010, approximately 150 of the concrete dams will be at least 50 years old, and nearly 100 of the dams will be 70 years old. The current condition of these structures reflects the influence of several factors that have promoted aging, such as initial shrinkage causing latent microcracking; expansion and contraction related to temperature cycles; larger infiltration entailing increased uplift; leaching and deposition of calcium salts that clog joints and drains; hydric swelling; freezing and thawing cycles; erosion; sulfation; and, alkali-aggregate reactions (AAR). This paper focused on the swelling due to AAR, since more than 20 dams have been affected by this condition. Hydro-Quebec's approach to prevent AAR was described. In response to Canadian Standards Association (CSA) concrete expansion tests, Hydro-Quebec no longer allows admixtures for its concrete structures. Rather, non-reactive aggregates are used in the concrete. This paper also discussed the evaluation of residual expansion time caused by the alkali-silica reaction (ASR), which has affected the dam at La Tuque in the Mauricie Region. Results of laboratory expansion tests have been compared with the average expansion rate measured at the La Tuque dam. It was estimated that the concrete should continue to swell for at least 20 years at the same rate as measured since 1979. After that, expansion may possibly slow down due to self-confinement in the concrete. However, if confinement increases in 2 directions, it is probable that the expansion accelerates in the third direction. 26 refs., 3 tabs., 8 figs.

    1998-01-01

    In December 1997 Quebec's Minister of Natural Resources requested that the Energy Commission advise him on the quota given to wind energy in the future energy development plans of Hydro-Quebec. The Commission's report to the Minister includes 18 recommendations. Among these is a recommendation that an assessment of wind resources be conducted as soon as possible to identify suitable sites for the installation of wind turbines. A provincial program for the development of wind energy is also recommended, to be initiated by the year 2002, and that it should proceed over the next nine years to reach a target production capacity of 450 MW by the year 2011. This production would come from the yearly installation of 60 to 70 wind turbines of 750 kV. The Commission also recommended that in the initial years costs for this wind energy not exceed that of the Le Nordais project, i.e. 5.8 cents per kWh. Any additional costs incurred in the generation of wind electricity over conventional hydro power should be assumed by the Quebec Government. Conversely, in instances where the wind power is sold to consumers outside of the province, Hydro-Quebec should pay for the full cost of this power. 8 tabs., 1 appendix

    An economic analysis of Quebec residential electricity demand was studied by micro-simulation models. These structural models describe all components which lead to decisions upon durable holdings and electric appliance usage. The demand for space and water heating systems was evaluated. Recent price change in favour of energy sources other than electricity were taken into account. Price and income elasticity ratios were found to be low, as expected when estimating short term use. The role played by socio-economic variables on the choice of space-water heating systems and electricity use was also examined. Recent conversions have indicated a trend toward preference by households in favour of natural gas or oil over electricity. 18 refs., 5 tabs., 1 fig

    Full Text Available Abstract Background Use of high daily doses of benzodiazepines is generally contraindicated for seniors. While both patient and physician factors may influence the use of high daily doses, previous research on the effect of patient factors has been extremely limited. The objectives of this study were to determine the one year prevalence of use of high daily doses of benzodiazepines, and examine physician and patient correlates of such use among Quebec community-dwelling seniors. Methods Patient information for 1423 community-dwelling Quebec seniors who participated in the Canadian Study of Health and Aging was linked to provincial health insurance administrative data bases containing detailed information on prescriptions received and prescribers. Results The standardized one year period prevalence of use of high daily doses of benzodiazepines was 7.9%. Use of high daily doses was more frequent among younger seniors and those who had reported anxiety during the previous year. Patients without cognitive impairment were more likely to receive high dose prescriptions from general practitioners, while those with cognitive impairment were more likely to receive high dose prescriptions from specialists. Conclusion High dose prescribing appears to be related to both patient and physician factors.

    Cette these est consacree a l'histoire de l'electrification rurale du Quebec, et, plus particulierement, a l'histoire des cooperatives d'electricite. Fondees par vagues successives a partir de 1945, les cooperatives rurales d'electricite ont ete actives dans plusieurs regions du Quebec et elles ont electrifie une partie significative des zones rurales. Afin de comprendre le contexte de la creation des cooperatives d'electricite, notre these debute (premiere partie) par une analyse du climat sociopolitique des annees precedant la naissance du systeme cooperatif d'electrification rurale. Nous y voyons de quelle facon l'electrification rurale devient progressivement, a partir de la fin des annees 1920, une question d'actualite a laquelle les divers gouvernements qui se succedent tentent de trouver une solution, sans engager---ou si peu---les fonds de l'Etat. En ce sens, la premiere etatisation et la mise sur pied d'Hydro-Quebec, en 1944, marquent une rupture quant au mode d'action privilegie jusque-la. La nouvelle societe d'Etat se voit cependant retirer son mandat d'electrifier le monde rural un an apres sa fondation, car le gouvernement Duplessis, de retour au pouvoir, prefere mettre en place son propre modele d'electrification rurale. Ce systeme repose sur des cooperatives d'electricite, soutenues par un organisme public, l'Office de l'electrification rurale (OER). L'OER suscite de grandes attentes de la part des ruraux et c'est par centaines qu'ils se manifestent. Cet engouement pour les cooperatives complique la tache de l'OER, qui doit superviser de nouvelles societes tout en assurant sa propre organisation.

    Rivers and effluents have been identified as major pathways for microplastics of terrestrial sources. Moreover, lakes of different dimensions and even in remote locations contain microplastics in striking abundances. This study investigates concentrations of microplastic particles at two lakes in central Italy (Lake Bolsena, Lake Chiusi). A total number of six Manta Trawls have been carried out, two of them one day after heavy winds occurred on Lake Bolsena showing effects on particle distribution of fragments and fibers of varying size categories. Additionally, 36 sediment samples from lakeshores were analyzed for microplastic content. In the surface waters 2.68 to 3.36 particles/m(3) (Lake Chiusi) and 0.82 to 4.42 particles/m(3) (Lake Bolsena) were detected, respectively. Main differences between the lakes are attributed to lake characteristics such as surface and catchment area, depth and the presence of local wind patterns and tide range at Lake Bolsena. An event of heavy winds and moderate rainfall prior to one sampling led to an increase of concentrations at Lake Bolsena which is most probable related to lateral land-based and sewage effluent inputs. The abundances of microplastic particles in sediments vary from mean values of 112 (Lake Bolsena) to 234 particles/kg dry weight (Lake Chiusi). Lake Chiusi results reveal elevated fiber concentrations compared to those of Lake Bolsena what might be a result of higher organic content and a shift in grain size distribution towards the silt and clay fraction at the shallow and highly eutrophic Lake Chiusi. The distribution of particles along different beach levels revealed no significant differences. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The spectacular progress made by nanosciences and nanotechnologies elicits as much hope and fear. Consequently, a great number of research and training initiatives on the ethical, environmental, economic, legal and social issues regarding nanotechnology development (Ne 3 LS) are emerging worldwide. In Quebec, Canada, a Task Force was mandated by NanoQuebec to conceive a Ne 3 LS research and training strategy to assess those issues. This Task Force brought together experts from universities, governments or industry working in nanosciences and nanotechnologies or in Ne 3 LS. Their resulting action plan, made public in November 2006, contained several recommendations, including the creation of a knowledge network (Ne 3 LS Network). In the following years, after consulting with numerous key players concerned with the possible impacts of nanosciences and nanotechnologies in Quebec, the Ne 3 LS Network was launched in January 2010 in partnership with the Fonds quebecois de la recherche sur la nature et les technologies, the Fonds quebecois de la recherche sur la societe et la culture and the Fonds de la recherche en sante du Quebec, NanoQuebec, the Institut de recherche Robert-Sauve en sante et en securite du travail as well as the University of Montreal. Its objectives are to 1) Foster the development of Ne 3 LS research activities (grants and fellowships); 2) Spearhead the Canadian and international Ne 3 LS network; 3) Take part in the training of researchers and experts; 4) Encourage the creation of interactive tools for the general public; 5) Facilitate collaboration between decision-makers and experts; 6) Involve the scientific community through a host of activities (symposium, conferences, thematic events); 7) Build multidisciplinary research teams to evaluate the impact of nanotechnology.

    Lakes worldwide are commonly oversaturated with CO{sub 2}, however the source of this CO{sub 2} oversaturation is not well understood. To examine the magnitude of the C flux to the atmosphere and determine if an excess of respiration (R) over gross primary production (GPP) is sufficient to account for this C flux, metabolic parameters and stable isotopes of dissolved O{sub 2} and C were measured in 23 Quebec lakes. All of the lakes sampled were oversaturated with CO{sub 2} over the sampling period, on average 221 {+-} 25%. However, little evidence was found to conclude that this CO{sub 2} oversaturation was the result of an excess of pelagic R over GPP. In lakes Croche and a l'Ours, where CO{sub 2} flux, R and GPP were measured weekly, the annual difference between pelagic GPP and R, or net primary production (NPP), was not sufficient to account for the size of the CO{sub 2} flux to the atmosphere. In Lac Croche average annual NPP was 14.4 mg C m{sup -2} d{sup -1} while the average annual flux of CO{sub 2} to the atmosphere was 34 mg C m{sup -2} d{sup -1}. In Lac a l'Ours average annual NPP was -9.1 mg C m{sup -2} d{sup -1} while the average annual flux of CO{sub 2} to the atmosphere was 55 mg C m{sup -2} d{sup -1}. In all of the lakes sampled, O{sub 2} saturation averaged 104.0 {+-} 1.7% during the ice-free season and the isotopic composition of dissolved O{sub 2} ({delta}{sup 18}O{sub DO}) was 22.9 {+-} 0.3 per mille , lower than atmospheric values and indicative of net autotrophy. Carbon evasion was not a function of R, nor did the isotopic signature of dissolved CO{sub 2} in the lakes present evidence of excess R over GPP. External inputs of C must therefore subsidize the lake to explain the continued CO{sub 2} oversaturation. The isotopic composition of dissolved inorganic C ({delta}{sup 13}C{sub DIC}) indicates that the CO{sub 2} oversaturation cannot be attributed to in situ aerobic respiration. {delta}{sup 13}C{sub DIC} reveals a source of excess

    This presentation described the application of flow forecasting at the Centre d'Expertise Hydrique du Quebec (CEHQ), an agency that provides expertise in hydrology and hydraulics. CEHQ ensures land management of public water and enforces the Dam Safety Act. It also provides support to municipalities in defining flood-risk areas and effective control of floods. Other responsibilities include the operation of hydrometric stations and 36 publicly-owned dams used for flood control, water supply, recreational activities and hydroelectricity. The role of stream flow forecasting within the decision making process was discussed and operational examples were presented to demonstrate the possibilities of forecast scenarios such as the one in place at the Kenogami River Basin in Quebec. Future challenges lie in improving the way information is communicated and evaluating the probability of occurrences associated with short-term precipitation scenarios to current weather conditions. tabs., figs.

    In January 1997, the government of Quebec, Canada, implemented a public/private prescription drug program that covered the entire population of the province. Under this program, the public sector collaborates with private insurers to protect all Quebecers from the high cost of drugs. This article outlines the principal features and history of the Quebec plan and draws parallels between the factors that led to its emergence and those that led to the passage of the Medicare Prescription Drug, Improvement and Modernization Act (MMA) in the United States. It also discusses the challenges and similarities of both programs and analyzes Quebec's ten years of experience to identify adjustments that may help U.S. policymakers optimize the MMA.

    The ice storm that struck Quebec in the winter of 1998 left millions of people without electricity because the accumulation of ice caused the collapse of hundreds of kilometres of high-voltage transmission lines and thousands of transmission towers. In order to optimize the security of its power grid, Hydro-Quebec contracted AREVA T and D to construct and install HVDCice{sup TM}, a transmission line de-icing system based on high-voltage direct current (HVDC) technology. The system is intended to ensure maximum electrical efficiency and guarantee a secure electricity supply. The system will generate up to 7200A of direct current in the transmission lines. This will raise their temperature thereby allowing the ice to melt and fall off. The system will be implemented at the Levis substation, a major connection point for the transmission lines of the province. The system also acts as a Static Var Compensator (SVC) to improve the power quality of the transmission network. The SVC will stabilize the voltage on the 735 kV power grid, which can fluctuate depending on the amount of electricity being consumed. This is the world's first HVDC-based de-icing and power quality system. The contract awarded to AREVA's T and D division is estimated at 25 million Euros. 1 fig.

    Socioeconomic position (SEP) is inversely associated with most oral health outcomes, but the patterns of association may vary depending on the specific outcome. We estimated associations between SEP and two oral health outcomes, dental caries and traumatic dental injuries (TDI), in Quebec children. We used data from the baseline visit of the QUALITY (QUebec Adipose and Lifestyle Investigation in Youth) Cohort, an ongoing study in Montreal and Quebec, Canada. The analytical sample included 590 children aged 8-10 years. Data on parents' SEP (household income, education) and children's health behaviours and involvement in sports were obtained through questionnaires and interviews. Oral health outcomes (dental caries and TDI in permanent teeth) were assessed by clinical oral exam. Negative binomial regression was used to model dental caries (DMFS index) and number of teeth with TDI adjusting for selected covariates. The mean (SD) DMFS and number of TDI were 0.61 (1.43) and 0.12 (0.43), respectively. Compared to the upper quartile of income, children in the lower quartile had a DMFS approximately 3 times higher (PRR=2.68, 95% CI: 1.43, 5.04). Adjusting for oral health and nutritional behaviours had no effect. Conversely, children in the highest income quartile had a 3 times higher number of teeth with TDI compared to the lowest quartile (PRR=3.14, 95% CI: 1.22, 8.08). Physical activity did not explain this relationship. Parents' education was not associated with dental caries or TDI. SEP seems to play a different role in the cause of dental caries and TDI.

We assessed colored dissolved organic matter (CDOM absorption at 440 nm (a(440CDOM and absorption slope (S300–500 in lakes using field sampling and optical remote sensing data for an area of 350 km2 in Central Yamal, Siberia. Applying a CDOM algorithm (ratio of green and red band reflectance for two high spatial resolution multispectral GeoEye-1 and Worldview-2 satellite images, we were able to extrapolate the a(λCDOM data from 18 lakes sampled in the field to 356 lakes in the study area (model R2 = 0.79. Values of a(440CDOM in 356 lakes varied from 0.48 to 8.35 m−1 with a median of 1.43 m−1. This a(λCDOM dataset was used to relate lake CDOM to 17 lake and lake catchment parameters derived from optical and radar remote sensing data and from digital elevation model analysis in order to establish the parameters controlling CDOM in lakes on the Yamal Peninsula. Regression tree model and boosted regression tree analysis showed that the activity of cryogenic processes (thermocirques in the lake shores and lake water level were the two most important controls, explaining 48.4% and 28.4% of lake CDOM, respectively (R2 = 0.61. Activation of thermocirques led to a large input of terrestrial organic matter and sediments from catchments and thawed permafrost to lakes (n = 15, mean a(440CDOM = 5.3 m−1. Large lakes on the floodplain with a connection to Mordy-Yakha River received more CDOM (n = 7, mean a(440CDOM = 3.8 m−1 compared to lakes located on higher terraces.

    The Quebec Emergency Department Management Guide (QEDMG) is a unique document with 78 recommendations designed to improve the organization of emergency departments (EDs) in the province of Quebec. However, no study has examined how this guide is perceived or used by rural health care management. We invited all directors of professional services (DPS), directors of nursing services (DNS), head nurses (HN), and emergency department directors (EDD) working in Quebec's rural hospitals to complete an online survey (144 questions). Simple frequency analyses (percentage [%] and 95% confidence interval) were conducted to establish general familiarity and use of the QEDMG, as well as perceived usefulness and implementation of its recommendations. Seventy-three percent (19/26) of Quebec's rural EDs participated in the study. A total of 82% (62/76) of the targeted stakeholders participated. Sixty-one percent of respondents reported being "moderately or a lot" familiar with the QEDMG, whereas 77% reported "almost never or sometimes" refer to this guide. Physician management (DPS, EDD) were more likely than nursing management (DNS and especially HN) to report "not at all" or "little" familiarity on use of the guide. Finally, 98% of the QEDMG recommendations were considered useful. Although the QEDMG is considered a useful guide for rural EDs, it is not optimally known or used in rural EDs, especially by physician management. Stakeholders should consider these findings before implementing the revised versions of the QEDMG.

    The Quebec Health Smart Card Project is advocating the use of a memory card software server[1] (SCAM) to implement a portable medical record (PMR) on a smart card. The PMR is viewed as an object that can be manipulated by SCAM's services. In fact, we can talk about a pseudo-object-oriented approach. This software architecture provides a flexible and evolutive way to manage and optimize the PMR. SCAM is a generic software server; it can manage smart cards as well as optical (laser) cards or other types of memory cards. But, in the specific case of the Quebec Health Card Project, SCAM is used to provide services between physicians' or pharmacists' software and IBM smart card technology. We propose to expose the concepts and techniques used to provide a generic environment to deal with smart cards (and more generally with memory cards), to obtain a dynamic an evolutive PMR, to raise the system global security level and the data integrity, to optimize significantly the management of the PMR, and to provide statistic information about the use of the PMR.

    Populations of lake trout, severely depleted in Lake Superior and virtually extirpated from the other Great Lakes because of sea lamprey predation and intense fishing, are now maintained by annual plantings of hatchery-reared fish in Lakes Michigan, Huron, and Ontario and parts of Lake Superior. The extensive coastal areas of the Great Lakes and proximity to large populations resulted in fishing pressure on planted lake trout heavy enough to push annual mortality associated with sport and commercial fisheries well above the critical level needed to reestablish self-sustaining stocks. The interagency, international program for rehabilitating lake trout includes controlling sea lamprey abundance, stocking hatchery-reared lake trout, managing the catch, and establishing sanctuaries where harvest is prohibited. Three lake trout sanctuaries have been established in Lake Michigan: the Fox Island Sanctuary of 121, 500 ha, in the Chippewa-Ottawa Treaty fishing zone in the northern region of the lake; the Milwaukee Reef Sanctuary of 160, 000 ha in midlake, in boundary waters of Michigan and Wisconsin; and Julian's Reef Sanctuary of 6, 500 ha, in Illinois waters. In northern Lake Huron, Drummond Island Sanctuary of 55, 000 ha is two thirds in Indian treaty-ceded waters in Michigan and one third in Ontario waters of Canada. A second sanctuary, Six Fathom Bank-Yankee Reef Sanctuary, in central Lake Huron contains 168, 000 ha. Sanctuary status for the Canadian areas remains to be approved by the Provincial government. In Lake Superior, sanctuaries protect the spawning grounds of Gull Island Shoal (70, 000 ha) and Devils Island Shoal (44, 000 ha) in Wisconsin's Apostle Island area. These seven sanctuaries, established by the several States and agreed upon by the States, Indian tribes, the U.S. Department of the Interior, and the Province of Ontario, contribute toward solving an interjurisdictional fishery problem.

    Amendments proposed by the Government of Quebec with respect to petroleum products regulations were described. The amending regulation provides a list of works which will no longer require ministerial authorization such as the removal of petroleum equipment, the installation of spill prevention systems, electrical works and repair of fueling areas, loading and unloading zones. An owner will not be required to remove an unused underground petroleum storage tank if it can be shown that it is impervious according to prescribed pressure tests, and that the period during which the equipment has been unused does not exceed five years. The draft regulations also provide precautionary measures that have to be taken prior to abandoning a tank

Esse dualismo simplista se acentuou após a chamada Revolução Tranqüila em 1960 quando a identidade do canadense francês, até então representado como um povo oprimido e humilhado pelo Outro, o inglês, minoria em seu próprio país, se transforma no quebequense moderno e ativo, maioria em seu “Estado”, que detém o poder para definir os rumos de seu destino.

    Lake Van in Eastern Anatolia (Turkey) is the largest terminal soda lake on Earth. The lake sedimentary profile covers ca. 600 ka (Stockhecke et al. 2014) Based on lithological changes, the presence of freshwater microfossils and close-to-freshwater pH value in the pore water, members of ICDP PALEOVAN concluded that Lake Van might have started as an open lake. Here we show paleontological and geochemical evidence in favour of this idea and constrain the time, when Lake Van likely transformed into a closed lake. Additionally we provide the first conceptual model of how this closure may have happened. Our archives of choice are inorganic and biogenic carbonates, separated by wet sieving. We identified microfossil assemblages (fraction > 125 µm) and performed high-resolution oxygen isotope (delta18O) and elemental (Mg/Ca, Sr/Ca) analyses of the fraction plants growing in the photic zone as food supply. These two aspects point to an increasing salinity in a shallowing lake. The delta18O values of inorganic carbonates are relatively low during the initial phase of Lake Van and increase abruptly (ca. 7‰) after 530 ka BP. At approximately the same time combination of Sr/Ca and Mg/Ca data suggest first occurrence of aragonite. Again, these findings suggest geochemical changes of the lake water concurrent with transition documented by microfossils. Comparison between Lake Van and Lake Ohrid (Lacey et al. 2016) delta18O data, precludes regional climate change (e.g.: increased evaporation) as the main driver of observed changes. With no evidence for increased volcanic or tectonic activity (e.g.: tephra layers, deformation structures, slumping) in the Lake Van sedimentary profile around 530 ka, it seems unlikely that a pyroclastic flow blocked the outflow of the lake. Alternatively, a portion of inflow has been diverged which might have caused a change in the hydrological balance and lake level falling below its outlet. However, as no geomorphological data confirming this

    An asbestos advisory committee was created in 1997 by Quebec's Ministry of Health to address concerns regarding exposure to asbestos fibres. Two sub-committees were subsequently formed. One sub-committee evaluated the pertinence and feasibility of assessing exposure in the general population, particularly in public buildings such as schools, while the other reviewed epidemiological studies in Quebec on mesothelioma, pulmonary cancers and asbestosis. Each sub-committee produced a report. This document summarizes the two reports and outlines the current scientific knowledge on the effects of asbestos on human health. The preventive programs and subsequent evaluations undertaken in Quebec with respect to sprayed asbestos in schools was described along with studies of asbestos exposure among workers in the mining sector. A study was also conducted within the asbestos processing industry to identify how many workers exceeded standard exposure limits. The standard time-weighted average exposure value currently in force in Quebec is 1 fibre per ml for chrysotile and 0.2 fibres per ml for amosite and crocidolite. A recommendation was made to revise this standard. In terms of outdoor air, the concentrations measured in recent years in mining towns have been generally very low. Along with asbestos-asphalt, asbestos waste taken to landfill sites may represent a significant source of exposure. A screening for asbestosis in the building and public works sector has shown that 1,500 workers (insulators, plumber-pipe fitters, elevator mechanics, fire protection mechanics and boiler-makers) experienced significant exposure to high concentrations of asbestos fibres in the ambient air. The 3 main health effects of asbestos exposure include mesothelioma of the pleura and peritoneum, pulmonary cancer and asbestosis. Each of these diseases appears after a latency period of 20 to 40 years, depending on the pathology. Epidemiological studies show a statistically significant increase

    Lake Whitefish Coregonus clupeaformis support some of the most valuable commercial freshwater fisheries in North America. Recent growth and condition decreases in Lake Whitefish populations in the Great Lakes have been attributed to the invasion of the dreissenid mussels, zebra mussels Dreissena polymorpha and quagga mussels D. bugensis, and the subsequent collapse of the amphipod, Diporeia, a once-abundant high energy prey source. Since 1993, Lake Champlain has also experienced the invasion and proliferation of zebra mussels, but in contrast to the Great Lakes, Diporeia were not historically abundant. We compared the diet, condition, and energy density of Lake Whitefish from Lake Champlain after the dreissenid mussel invasion to values for those of Lake Whitefish from Lakes Michigan, Huron, Erie, and Ontario. Lake Whitefish were collected using gill nets and bottom trawls, and their diets were quantified seasonally. Condition was estimated using Fulton's condition factor (K) and by determining energy density. In contrast to Lake Whitefish from some of the Great Lakes, those from Lake Champlain Lake Whitefish did not show a dietary shift towards dreissenid mussels, but instead fed primarily on fish eggs in spring, Mysis diluviana in summer, and gastropods and sphaeriids in fall and winter. Along with these dietary differences, the condition and energy density of Lake Whitefish from Lake Champlain were high compared with those of Lake Whitefish from Lakes Michigan, Huron, and Ontario after the dreissenid invasion, and were similar to Lake Whitefish from Lake Erie; fish from Lakes Michigan, Huron, and Ontario consumed dreissenids, whereas fish from Lake Erie did not. Our comparisons of Lake Whitefish populations in Lake Champlain to those in the Great Lakes indicate that diet and condition of Lake Champlain Lake Whitefish were not negatively affected by the dreissenid mussel invasion.

    The Clock Drawing Test (CDT) is frequently used to screen for cognitive impairment, however, normative data for Rouleau et al.'s scoring system are scarce. The present study aims to provide norms for Rouleau et al.'s scoring system that are tailored to Quebec French-speaking mid- and older aged healthy adults. Six researchers from various research centers across the Province of Quebec (Canada) sent anonymous data for 593 (391 women) healthy community-dwelling volunteers (age range: 43-93 years; education range: 5-23 years) who completed the CDT 'drawing on command' version. This command version (setting the clock hands to 11:10, without a pre-drawn circle) was administrated as part of a more extensive neuropsychological assessment, or along with cognitive screening instruments. Each drawn clock was scored according to the quantitative criteria set by Rouleau et al.'s scoring system. CDT scores were significantly correlated with age (r(592) = -.132, p = .001) and years of education (r(592) = .116, p = .005), but not with sex (r(592) = .065, p = .112). Since data were skewed towards higher test scores, the percentiles method was used for analysis. Percentile ranks stratified by age and education are presented. These normative data for Rouleau et al.'s scoring system will contribute towards adequately screening for cognitive decline in Quebec French-speaking healthy adults, by also taking into account individual characteristics such as age and education.

    This paper describes the urban heat island in Quebec City on a typical clear winter night. This is a follow-up to a study made on a summer night in August 1980; the reader will find a detailed description of the region in Leduc et al. (1980). On February 25, 1980 at 21:30 EST, nearly 200 measurements of temperature were taken at preselected points by 17 mobile observers; a mini-sonde was launched near the Duberger meteorological tower while upper air data were obtained from a sonde launched at Valcartier CFB. Additional data were available from the five regular climatological stations in greater Quebec City and from 2 other thermographs in order to evaluate cooling rates. On the day of the 25th, a developing low pressure area over the eastern coast brought cold air from the northwest toward Quebec City. On that day, the maximum temperature was - 1 °C while the minimum on the following night dropped to - 19 °C. At the time of the experiment, the sky was clear and the winds were westerly at 1.5 m s-1 at the surface and northwesterly at 6 m s-1 at 122 m. A strong inversion was present in the lowest 200 m while upper inversions were noted on the upper air sounding. As noted in the summer experiment, cooling rates, according to the Oke et al. (1972) criteria, reflected a rural behaviour at all stations equipped with a thermograph. It is to be noted that no data on cooling rates are available for the highly urbanized sectors. One notes a relatively warm zone in the downtown area where temperature reached - 8 °C; there is also a cold zone, at the same location as during the summer experiment. The mean temperature gradient between the urban and rural sectors was 5 °C, which is comparable with that observed in August 1979 (6 °C). Thus, the urban heat island does not seem to be more intense in winter than in summer. Relatively large areas of uniform temperature were detected at places where the summer experiment indicated sharp spatial contrasts; this could be

    Climate change has been shown to increase the number of mountain lakes across various mountain ranges in the World. In Central Asia, and in particular on the territory of Uzbekistan, a detailed assessment of glacier lakes and their evolution over time is, however lacking. For this reason we created the first detailed inventory of mountain lakes of Uzbekistan based on recent (2002-2014) satellite observations using WorldView-2, SPOT5, and IKONOS imagery with a spatial resolution from 2 to 10m. This record was complemented with data from field studies of the last 50years. The previous data were mostly in the form of inventories of lakes, available in Soviet archives, and primarily included localized in-situ data. The inventory of mountain lakes presented here, by contrast, includes an overview of all lakes of the territory of Uzbekistan. Lakes were considered if they were located at altitudes above 1500m and if lakes had an area exceeding 100m 2 . As in other mountain regions of the World, the ongoing increase of air temperatures has led to an increase in lake number and area. Moreover, the frequency and overall number of lake outburst events have been on the rise as well. Therefore, we also present the first outburst assessment with an updated version of well-known approaches considering local climate features and event histories. As a result, out of the 242 lakes identified on the territory of Uzbekistan, 15% are considered prone to outburst, 10% of these lakes have been assigned low outburst potential and the remainder of the lakes have an average level of outburst potential. We conclude that the distribution of lakes by elevation shows a significant influence on lake area and hazard potential. No significant differences, by contrast, exist between the distribution of lake area, outburst potential, and lake location with respect to glaciers by regions. Copyright © 2017 Elsevier B.V.

    The Neoarchean (ca. 2728 Ma) anorthosite-bearing Doré Lake Complex in the northeastern Abitibi subprovince, Quebec, was emplaced into an association of intra-oceanic tholeiitic basalts and gabbros known as the Obatogamau Formation. The Obatogamau Formation constitutes the lower part of the Roy Group, which is composed of two cycles of tholeiitic-to-calc-alkaline volcanic and volcaniclastic rocks, siliciclastic and chemical sedimentary rocks, and layered mafic-to-ultramafic sills. In this study, we report major and trace element results, and Nd, Sr, Pb and O isotope data for anorthosites, leucogabbros, gabbros and mafic dykes from the Doré Lake Complex and spatially associated basalts and gabbros of the Obatogamau Formation to assess their petrogenetic origin and geodynamic setting. Field and petrographic observations indicate that the Doré Lake Complex and associated volcanic rocks underwent extensive metamorphic alteration under greenschist facies conditions, resulting in widespread epidotization (20-40%) and chloritization (10-40%) of many rock types. Plagioclase recrystallized mainly to anorthite and albite endmembers, erasing intermediate compositions. Metamorphic alteration also led to the mobilization of many elements (e.g., LILE and transition metals) and to significant disturbance of the Rb-Sr and U-Pb isotope systems, resulting in 1935 ± 150 and 3326 ± 270 Ma errorchron ages, respectively. The Sm-Nd isotope system was less disturbed, yielding an errorchron age of 2624 ± 160 Ma. On many binary major and trace element diagrams, the least altered anorthosites and leucogabbros, and the gabbros and mafic dykes of the Doré Lake Complex plot in separate fields, signifying the presence of two distinct magma types in the complex. The gabbros and mafic dykes in the Doré Lake Complex share the geochemical characteristics of tholeiitic basalts and gabbros in the Obatogamau Formation, suggesting a possible genetic link between the two rock associations.

  14. Lake-level frequency analysis for Devils Lake, North Dakota

    Wiche, Gregg J.; Vecchia, Aldo V.

    1996-01-01

    Two approaches were used to estimate future lake-level probabilities for Devils Lake. The first approach is based on an annual lake-volume model, and the second approach is based on a statistical water mass-balance model that generates seasonal lake volumes on the basis of seasonal precipitation, evaporation, and inflow. Autoregressive moving average models were used to model the annual mean lake volume and the difference between the annual maximum lake volume and the annual mean lake volume. Residuals from both models were determined to be uncorrelated with zero mean and constant variance. However, a nonlinear relation between the residuals of the two models was included in the final annual lakevolume model.Because of high autocorrelation in the annual lake levels of Devils Lake, the annual lake-volume model was verified using annual lake-level changes. The annual lake-volume model closely reproduced the statistics of the recorded lake-level changes for 1901-93 except for the skewness coefficient. However, the model output is less skewed than the data indicate because of some unrealistically large lake-level declines. The statistical water mass-balance model requires as inputs seasonal precipitation, evaporation, and inflow data for Devils Lake. Analysis of annual precipitation, evaporation, and inflow data for 1950-93 revealed no significant trends or long-range dependence so the input time series were assumed to be stationary and short-range dependent.Normality transformations were used to approximately maintain the marginal probability distributions; and a multivariate, periodic autoregressive model was used to reproduce the correlation structure. Each of the coefficients in the model is significantly different from zero at the 5-percent significance level. Coefficients relating spring inflow from one year to spring and fall inflows from the previous year had the largest effect on the lake-level frequency analysis.Inclusion of parameter uncertainty in the model

    Recent observations of spawning lake trout Salvelinus namaycush near Drummond Island in northern Lake Huron indicate that lake trout use drumlins, landforms created in subglacial environments by the action of ice sheets, as a primary spawning habitat. From these observations, we generated a hypothesis that may in part explain locations chosen by lake trout for spawning. Most salmonines spawn in streams where they rely on streamflows to sort and clean sediments to create good spawning habitat. Flows sufficient to sort larger sediment sizes are generally lacking in lakes, but some glacial bedforms contain large pockets of sorted sediments that can provide the interstitial spaces necessary for lake trout egg incubation, particularly if these bedforms are situated such that lake currents can penetrate these sediments. We hypothesize that sediment inclusions from glacial scavenging and sediment sorting that occurred during the creation of bedforms such as drumlins, end moraines, and eskers create suitable conditions for lake trout egg incubation, particularly where these bedforms interact with lake currents to remove fine sediments. Further, these bedforms may provide high-quality lake trout spawning habitat at many locations in the Great Lakes and may be especially important along the southern edge of the range of the species. A better understanding of the role of glacially-derived bedforms in the creation of lake trout spawning habitat may help develop powerful predictors of lake trout spawning locations, provide insight into the evolution of unique spawning behaviors by lake trout, and aid in lake trout restoration in the Great Lakes.

    Rainy Lake contains a native population of lake sturgeon Acipenser fulvescens that has been largely unstudied. The aims of this study were to document the population characteristics of lake sturgeon in Rainy Lake and to relate environmental factors to year-class strength for this population. Gill-netting efforts throughout the study resulted in the capture of 322 lake sturgeon, including 50 recaptures. Lake sturgeon in Rainy Lake was relatively plump and fast growing compared with a 32-population summary. Population samples were dominated by lake sturgeon between 110 and 150 cm total length. Age–structure analysis of the samples indicated few younger (<10 years) lake sturgeon, but the smallest gill net mesh size used for sampling was 102 mm (bar measure) and would not retain small sturgeon. Few lake sturgeon older than age 50 years were captured, and maximum age of sampled fish was 59 years. Few correlations existed between lake sturgeon year-class indices and both annual and monthly climate variables, except that mean June air temperature was positively correlated with year-class strength. Analysis of Rainy Lake water elevation and resulting lake sturgeon year-class strength indices across years yielded consistent but weak negative correlations between late April and early June, when spawning of lake sturgeon occurs. The baseline data collected in this study should allow Rainy Lake biologists to establish more specific research questions in the future.

    Full Text Available The zooplankton communities of two basins of a large lake, Lake Constance, were compared during the years 2002 and 2003. The two basins differ in morphology, physical and chemical conditions. The Upper Lake basin has a surface area of 470 km2, a mean depth of 100 and a maximum depth of 250 m; the Lower Lake basin has a surface area of 62 km2, a mean depth of only 13 and a maximum depth of 40 m. Nutrient, chlorophyll-a concentrations and mean temperatures are somewhat higher in the Lower than in the Upper Lake. Total abundance of rotifers (number per m2 lake surface was higher and rotifer development started earlier in the year in the Lower than in the Upper Lake. Total abundance of crustaceans was higher in the Upper Lake in the year 2002; in the year 2003 no difference in abundance could be detected between the lake basins, although in summer crustacean abundance was higher in the Lower than in the Upper Lake. Crustacean communities differed significantly between lake basins while there was no apparent difference in rotifer communities. In the Lower Lake small crustaceans, like Bosmina spp., Ceriodaphnia pulchella and Thermocyclops oithonoides prevailed. Abundance (number per m2 lake surface of predatory cladocerans, large daphnids and large copepods was much lower in the Lower than in the Upper Lake, in particular during the summer months. Ordination with nonmetric multidimensional scaling (NMS separated communities of both lakes along gradients that correlated with temperature and chlorophyll a concentration. Clutches of copepods were larger in the Lower than in the Upper Lake. No difference could be detected in clutch size of large daphnids between lake basins. Our results show that zooplankton communities in different basins of Lake Constance can be very different. They further suggest that the lack of large crustaceans in particular the lack of large predatory cladocerans in the Lower Lake can have negative effects on growth and

    Native lake trout (Salvelinus namaycush) once thrived in the deep waters of eastern Lake Erie. The impact of nearly 70 years of unregulated exploitation and over 100 years of progressively severe cultural eutrophication resulted in the elimination of lake trout stocks by 1950. Early attempts to restore lake trout by stocking were unsuccessful in establishing a self-sustaining population. In the early 1980s, New York's Department of Environmental Conservation, Pennsylvania's Fish and Boat Commission, and the U.S. Fish and Wildlife Service entered into a cooperative program to rehabilitate lake trout in the eastern basin of Lake Erie. After 11 years of stocking selected strains of lake trout in U.S. waters, followed by effective sea lamprey control, lake trout appear to be successfully recolonizing their native habitat. Adult stocks have built up significantly and are expanding their range in the lake. Preliminary investigations suggest that lake trout reproductive habitat is still adequate for natural reproduction, but natural recruitment has not been documented. Future assessments will be directed toward evaluation of spawning success and tracking age-class cohorts as they move through the fishery.

    Soda lakes are saline and alkaline ecosystems that are believed to have existed throughout the geological record of Earth. They are widely distributed across the globe, but are highly abundant in terrestrial biomes such as deserts and steppes and in geologically interesting regions such as the East African Rift valley. The unusual geochemistry of these lakes supports the growth of an impressive array of microorganisms that are of ecological and economic importance. Haloalkaliphilic Bacteria and Archaea belonging to all major trophic groups have been described from many soda lakes, including lakes with exceptionally high levels of heavy metals. Lonar Lake is a soda lake that is centered at an unusual meteorite impact structure in the Deccan basalts in India and its key physicochemical and microbiological characteristics are highlighted in this article. The occurrence of diverse functional groups of microbes, such as methanogens, methanotrophs, phototrophs, denitrifiers, sulfur oxidizers, sulfate reducers and syntrophs in soda lakes, suggests that these habitats harbor complex microbial food webs that (a) interconnect various biological cycles via redox coupling and (b) impact on the production and consumption of greenhouse gases. Soda lake microorganisms harbor several biotechnologically relevant enzymes and biomolecules (for example, cellulases, amylases, ectoine) and there is the need to augment bioprospecting efforts in soda lake environments with new integrated approaches. Importantly, some saline and alkaline lake ecosystems around the world need to be protected from anthropogenic pressures that threaten their long-term existence. PMID:23178675

  1. The regional climate model as a tool for long-term planning of Quebec water resources

    2008-01-01

    'Full text': In recent years, important progress has been made in downscaling GCM (Global Climate Model) projections to a resolution where hydrological studies become feasible. Climate change simulations performed with RCMs (Regional Climate Models) have reached a level of confidence that allows us to take advantage of this information in long-term planning of water resources. The RCMs' main advantage consist in their construction based on balanced land as well as atmosphere water and energy budgets, and on their inclusion of feedbacks between the surface and the atmosphere. Such models therefore generate sequences of weather events, providing long time series of hydro-climatic variables that are internally consistent, allowing the analysis of hydrologic regimes. At OURANOS, special attention is placed on the hydrological cycle, given its key role on socioeconomic activities. The Canadian Regional Climate Model (CRCM) was developed as a potential tool to provide climate projections at the watershed scale. Various analyses performed over small basins in Quebec provide information on the level of confidence we have in the CRCM for use in hydrological studies. Even though this approach is not free of uncertainty, it was found useful by some water resource managers and hence this information should be considered. One of the keys to retain usefulness, despite the associated uncertainties, is to make use of more than a single regional climate projection. This approach will allow for the evaluation of the climate change signal and its associated level of confidence. Such a methodology is already applied by Hydro-Quebec in the long-term planning of its water resources for hydroelectric generation over the Quebec territory. (author)

    Advances in technology regarding underground transformers was discussed. After more than 3 years of research, CITEQ (Centre d'innovation sur le transport d'energie du Quebec), a new company founded by Hydro-Quebec and ABB, is on the verge of a breakthrough with a new submersible transformer with solid insulation. This transformer was specially designed for use in underground electric networks. The new transformer is a good alternative to conventional oil transformers which have a high risk of pollution mainly due to corrosion, leaks, explosions or fires. Also, the outer shell of the new transformer is composed of composite material which will eliminate the need for maintenance. The service life of the new transformer is expected to be approximately 30 to 40 years. CITEQ is hoping that this new technology will benefit the residential sector which is powered by underground distribution networks. 1 fig

    Simon Lévesque

    Full Text Available During the summer of 2012, a major Legionella pneumophila serogroup 1 outbreak occurred in Quebec City, Canada, which caused 182 declared cases of Legionnaire's disease and included 13 fatalities. Legionella pneumophila serogroup 1 isolates from 23 patients as well as from 32 cooling towers located in the vicinity of the outbreak were recovered for analysis. In addition, 6 isolates from the 1996 Quebec City outbreak and 4 isolates from patients unrelated to both outbreaks were added to allow comparison. We characterized the isolates using pulsed-field gel electrophoresis, sequence-based typing, and whole genome sequencing. The comparison of patients-isolated strains to cooling tower isolates allowed the identification of the tower that was the source of the outbreak. Legionella pneumophila strain Quebec 2012 was identified as a ST-62 by sequence-based typing methodology. Two new Legionellaceae plasmids were found only in the epidemic strain. The LVH type IV secretion system was found in the 2012 outbreak isolates but not in the ones from the 1996 outbreak and only in half of the contemporary human isolates. The epidemic strains replicated more efficiently and were more cytotoxic to human macrophages than the environmental strains tested. At least four Icm/Dot effectors in the epidemic strains were absent in the environmental strains suggesting that some effectors could impact the intracellular replication in human macrophages. Sequence-based typing and pulsed-field gel electrophoresis combined with whole genome sequencing allowed the identification and the analysis of the causative strain including its likely environmental source.

  5. Hydro-Quebec environmental performance report - 1998 : our commitment for today and tomorrow

    International Nuclear Information System (INIS)

    1999-01-01

    Hydro-Quebec's commitment to produce clean, renewable and safe energy was reviewed in this environmental performance report. In 1998, the utility's total installed capacity was 31,472 MW, 29,203 of which was hydroelectric. A total of 675 MW was generated by nuclear energy, and 1,594 MW was generated by thermal energy. The issue of atmospheric emissions from hydroelectric generating stations in comparison with other energy options was discussed. Hydro-Quebec takes environmental concerns into consideration at all stages in the life-cycle of its products, services and facilities, in order to meet environmental standards, prevent pollution, manage impacts at source, mitigate negative impacts and maximize positive impacts. The biggest environmental challenges facing the utility in 1998 was the January ice storm which left 40 per cent of all customers of the Distribution Division without power. More than 3,400 km of distribution lines were damaged. The system was completely restored by 1998. The main environmental consequences of the storm were spills of insulating oils, the impact on vegetation, the recovery of materials left in the field, and restoration of sites after the storm. Other highlights from 1998 include: (1) ISO 14001 implementation efforts, (2) adoption of a new environment policy, (3) participation by Hydro-Quebec in the founding of the Canadian Hydropower Association to promote the advantages of hydroelectricity to governments and the public, (4) the development of a series of measures to optimize certain generating facilities, (5) implementation of a program for evaluating the environmental compliance of all transmission substations, (6) the publication of a guide to ornamental trees and shrubs as part of the campaign to learn about the behaviour of overhanging branches which are the main cause of service interruptions on distribution lines, (7) the start up work to reinforce the transmission system, and (8) the recovery, reuse, recycling or energy

    Background: Predicted rise in global mean temperature and intensification of heat waves associated with climate change present an increasing challenge for occupational health and safety. Although important scientific knowledge has been gathered on the health effects of heat, very few studies have focused on quantifying the association between outdoor heat and mortality or morbidity among workers. Objective: To quantify the association between occupational heat-related illnesses and exposure to summer outdoor temperatures. Methods: We modeled 259 heat-related illnesses compensated by the Workers' Compensation Board of Quebec between May and September, from 1998 to 2010, with maximum daily summer outdoor temperatures in 16 health regions of Quebec (Canada) using generalized linear models with negative binomial distributions, and estimated the pooled effect sizes for all regions combined, by sex and age groups, and for different time lags with random-effect models for meta-analyses. Results: The mean daily compensation count was 0.13 for all regions of Quebec combined. The relationship between daily counts of compensations and maximum daily temperatures was log-linear; the pooled incidence rate ratio (IRR) of daily heat-related compensations per 1 °C increase in daily maximum temperatures was 1.419 (95% CI 1.326 to 1.520). Associations were similar for men and women and by age groups. Increases in daily maximum temperatures at lags 1 and 2 and for two and three-day lag averages were also associated with increases in daily counts of compensations (IRRs of 1.206 to 1.471 for every 1 °C increase in temperature). Conclusion: This study is the first to quantify the association between occupational heat-related illnesses and exposure to summer temperatures in Canada. The model (risk function) developed in this study could be useful to improve the assessment of future impacts of predicted summer outdoor temperatures on workers and vulnerable groups, particularly in

    2001-09-01

    Lacustrine deposits exposed around Lake Aricota, Peru (17° 22‧S), a 7.5-km2 lake dammed by debris flows, provide a middle to late Holocene record of lake-level fluctuations. Chronological context for shoreline deposits was obtained from radiocarbon dating of vascular plant remains and other datable material with minimal 14C reservoir effects (<350 yr). Diatomites associated with highstands several meters above the modern lake level indicate wet episodes. Maximum Holocene lake level was attained before 6100 14C yr B.P. and ended ∼2700 14C yr B.P. Moderately high lake levels occurred at 1700 and 1300 14C yr B.P. The highstand at Lake Aricota during the middle Holocene is coeval with a major lowstand at Lake Titicaca (16°S), which is only 130 km to the northeast and shares a similar climatology. Comparisons with other marine and terrestrial records highlight emerging contradictions over the nature of mid-Holocene climate in the central Andes.

    This paper provided an outline of risk management and communications strategies used by the Centre d'Expertise Hydrique du Quebec (CEHQ) in its dam safety program. The CEHQ manages, monitors and maintains dams in Quebec. Dam monitoring occurs on a yearly basis for high capacity dams. The Quebec Dam Safety Act (DSA) requires that each dam owner whose consequence category is assessed at moderate or higher to draw up an emergency action plan which is then supplied to the municipality where the dam is located. If an emergency occurs, a communication process is established between the CEHQ, the Municipal Civil Security Organization (OMSC) and the Quebec Ministry of Public Security (MSP). The emergency communications procedure was adopted by CEHG to clarify to the roles and responsibilities of each organization involved. CEHG's emergency planning committee is comprised of municipal agencies, dam officials, and a range of other partners. The committee was formed after a study conducted in 1997 which investigated the effects of flooding in the La Lievre watershed. Emergency planning for the municipalities involved has taken place in 6 steps, 5 of which have been put in place. The committee is currently preparing its risk communication strategy as the final stage in its emergency planning strategy. The purpose of the strategy is to both inform and create a greater sense of responsibility among members of the public. Several campaigns have been launched to inform citizens of the potential risks involved if any of the 17 dams which form part of the Lievre basin are breached. Dam officials are also planning to hold public meetings to inform citizens of the municipal zones and buildings at greater risk of flooding. It was concluded that the risk communication strategy adopted by the CEHQ will help municipalities, individuals, and communities to prepare adequate and informed emergency plans. 5 refs., 1 fig.

    Engineered NanoMaterials (NM) offer an opportunity to develop a wide variety of new products with unique properties but many studies have shown potential OHS risks specific to NM. Addressing these risks requires knowledge about release of NM into the workplaces. This research aimed to map the state of nanotechnology OHS practices in Quebec through a questionnaire following a first contact by telephone when possible and by compiling the type and volumes of NM used as well as gathering information related to the working conditions and OHS aspects. This survey was conducted among 1310 Quebec industries and 653 researchers working in different specialties potentially involved in the development/production/distribution/integration of NM and use of NM containing products. Overall, 90 questionnaires, including 51 from the industries, were completed. These showed that NM are mainly used into the powder form, in many different sectors and deserve a wide range of markets. The prevention measures implemented vary widely from a workplace to another but about one third of the participants report that they have implemented NP adapted prevention measures but they remain worried on some specific operations. More than 50% of the participants request more information about the safe laboratory/plant design, toxicity, regulation, good work practices and prevention measures, efficiency of personal protective equipment and environmental impacts.

  16. Spatial and temporal genetic diversity of lake whitefish (Coregonus clupeaformis (Mitchill)) from Lake Huron and Lake Erie

    Lake whitefish (Coregonus clupeaformis (Mitchill)) are important commercially, culturally, and ecologically in the Laurentian Great Lakes. Stocks of lake whitefish in the Great Lakes have recovered from low levels of abundance in the 1960s. Reductions in abundance, loss of habitat and environmental degradation can be accompanied by losses of genetic diversity and overall fitness that may persist even as populations recover demographically. Therefore, it is important to be able to identify stocks that have reduced levels of genetic diversity. In this study, we investigated patterns of genetic diversity at microsatellite DNA loci in lake whitefish collected between 1927 and 1929 (historical period) and between 1997 and 2005 (contemporary period) from Lake Huron and Lake Erie. Genetic analysis of lake whitefish from Lakes Huron and Erie shows that the amount of population structuring varies from lake to lake. Greater genetic divergences among collections from Lake Huron may be the result of sampling scale, migration patterns and demographic processes. Fluctuations in abundance of lake whitefish populations may have resulted in periods of increased genetic drift that have resulted in changes in allele frequencies over time, but periodic genetic drift was not severe enough to result in a significant loss of genetic diversity. Migration among stocks may have decreased levels of genetic differentiation while not completely obscuring stock boundaries. Recent changes in spatial boundaries to stocks, the number of stocks and life history characteristics of stocks further demonstrate the potential of coregonids for a swift and varied response to environmental change and emphasise the importance of incorporating both spatial and temporal considerations into management plans to ensure that diversity is preserved.

    This paper reported on a study that investigated on-farm anaerobic digesters using technical and economic analyses based on scenarios adapted to the regulatory and economic context of the swine sector in the province of Quebec. Three scenarios were chosen to represent operating conditions in the swine sector. An economic analysis was conducted to determine the profitability of each scenario. Preliminary results showed that this type of project under current conditions in Quebec generates little profit. If thermal use of biogas is considered, the challenge lies in producing biogas at a lower cost than that of natural gas. The best-case scenario in the present study showed a production cost of $0.65 per m{sup 3} of methane giving a 5-year payback. If biogas is used to generate electricity, the challenge lies in producing electricity at a cost lower than $0.0746 per kWh when it is used directly at the farm, or to obtain a price of $0.112 per kWh so it can be resold on the power grid.

    A prospective cohort study. To describe health services utilization for low back pain in the province of Quebec, Canada, and to compare it with North American guidelines. The Quebec Task Force and the Agency for Health Care Planning and Research (United States) published guidelines for the management of low back pain in 1987 and 1994, respectively. A cohort of 2147 adults with low back pain identified at the Quebec Worker's Compensation Board were selected randomly and observed over 2 years' time for their health care utilization profile. During the study period, 57.8% of the workers still under active care 7 weeks after their back injury had not yet been referred to a specialist. Specialized imaging techniques were obtained by 4.5% of the patients, with a delay of 7 weeks or more in 66% of them. Surgery was performed on 1.6% of the patients. The presence of an initial specific diagnosis and proximity to a university hospital significantly increased utilization rate and reduced the delays. Health services utilization for back pain in Quebec was equal or lower to what currently is practiced elsewhere, but access to specialists was not meeting the current recommendations. This would represent a 12% net increase in new specialist contacts and a quicker access in 39% who saw a specialist. Before such an effort can be considered, health care planners will need a better definition of the role of the specialist consultation in the guidelines and scientific evidence specifically addressing their benefit in primary care, especially in the absence of a specific diagnosis.

  19. Vulnerability of Quebec drinking-water treatment plants to cyanotoxins in a climate change context.

    2010-09-01

    Cyanobacteria are a growing concern in the province of Quebec due to recent highly publicised bloom episodes. The health risk associated with the consumption of drinking water coming from contaminated sources was unknown. A study was undertaken to evaluate treatment plants' capacity to treat cyanotoxins below the maximum recommended concentrations of 1.5 microg/L microcystin-LR (MC-LR) and the provisional concentration of 3.7 microg/L anatoxin-a, respectively. The results showed that close to 80% of the water treatment plants are presently able to treat the maximum historical concentration measured in Quebec (5.35 microg/L MC-LR equ.). An increase, due to climate change or other factors, would not represent a serious threat because chlorine, the most popular disinfectant, is effective in treating MC-LR under standard disinfection conditions. The highest concentration of anatoxin-a (2.3 microg/L) measured in natural water thus far in source water is below the current guideline for treated waters. However, higher concentrations of anatoxin-a would represent a significant challenge for the water industry as chlorine is not an efficient treatment option. The use of ozone, potassium permanganate or powder activated carbon would have to be considered.

    Bullying has become a significant public health issue, particularly among youth. This study documents cyberbullying, homophobic bullying and bullying at school or elsewhere and their correlates among both heterosexual and sexual-minority high school students in Quebec (Canada). A representative sample of 8194 students aged 14-20 years was recruited in Quebec (Canada) high schools. We assessed cyberbullying, homophobic bullying and bullying at school or elsewhere in the past 12 months and their association with current self-esteem and psychological distress as well as suicidal ideations. Bullying at school or elsewhere was the most common form of bullying (26.1%), followed by cyberbullying (22.9%) and homophobic bullying (3.6%). Overall, girls and sexual-minority youth were more likely to experience cyberbullying and other forms of bullying as well as psychological distress, low self-esteem and suicidal ideations. The three forms of bullying were significantly and independently associated with all mental health outcomes. The results underscore the relevance of taking into account gender and sexual orientation variations in efforts to prevent bullying experience and its consequences. Crown Copyright © 2015.

    We collected lake whitefish Coregonus clupeaformis off Alpena and Tawas City, Michigan, USA in Lake Huron and off Muskegon, Michigan USA in Lake Michigan during 2002–2004. We determined energy density and percent dry weight for lake whitefish from both lakes and lipid content for Lake Michigan fish. Energy density increased with increasing fish weight up to 800 g, and then remained relatively constant with further increases in fish weight. Energy density, adjusted for weight, was lower in Lake Huron than in Lake Michigan for both small (≤800 g) and large fish (>800 g). Energy density did not differ seasonally for small or large lake whitefish or between adult male and female fish. Energy density was strongly correlated with percent dry weight and percent lipid content. Based on data from commercially caught lake whitefish, body condition was lower in Lake Huron than Lake Michigan during 1981–2003, indicating that the dissimilarity in body condition between the lakes could be long standing. Energy density and lipid content in 2002–2004 in Lake Michigan were lower than data for comparable sized fish collected in 1969–1971. Differences in energy density between lakes were attributed to variation in diet and prey energy content as well as factors that affect feeding rates such as lake whitefish density and prey abundance.

    Lake trout refuges in the Apostle Islands region of Lake Superior are analogous to the concept of marine protected areas. These refuges, established specifically for lake trout (Salvelinus namaycush) and closed to most forms of recreational and commercial fishing, were implicated as one of several management actions leading to successful rehabilitation of Lake Superior lake trout. To investigate the potential significance of Gull Island Shoal and Devils Island Shoal refuges for populations of not only lake trout but also other fish species, relative abundances of lake trout, lake whitefish (Coregonus clupeaformis), and cisco (Coregonus artedi) were compared between areas sampled inside versus outside of refuge boundaries. During 1982–2010, lake trout relative abundance was higher and increased faster inside the refuges, where lake trout fishing was prohibited, than outside the refuges. Over the same period, lake whitefish relative abundance increased faster inside than outside the refuges. Both evaluations provided clear evidence that refuges protected these species. In contrast, trends in relative abundance of cisco, a prey item of lake trout, did not differ significantly between areas inside and outside the refuges. This result did not suggest indirect or cascading refuge effects due to changes in predator levels. Overall, this study highlights the potential of species-specific refuges to benefit other fish species beyond those that were the refuges' original target. Improved understanding of refuge effects on multiple species of Great Lakes fishes can be valuable for developing rationales for refuge establishment and predicting associated fish community-level effects.

  4. Hydro-Quebec's survey on outage cost in industries

    1990-01-01

    In 1989 Hydro-Quebec completed a survey on the cost of power interruptions to its industrial customers. A total of 11,000 firms formed the base of the survey, which was reduced to 1,647 for analysis purposes. The questionnaire was designed around the concept of representation of knowledge. The costs of various situations were inferred for every enterprise on the basis of knowledge obtained through the surveys. The results of the survey describe the variation in costs of interruption as a function of time of occurrence, duration and advance notice. These costs are expressed in terms of a reference case by the equivalent hourly cost. The magnitude of the cost of the reference interruption is designated the reference cost of undelivered energy. This paper describes the methodology of the survey but does not include survey results. 4 refs., 2 tabs

  5. Hazards of volcanic lakes: analysis of Lakes Quilotoa and Cuicocha, Ecuador

    2008-01-01

    Full Text Available Volcanic lakes within calderas should be viewed as high-risk systems, and an intensive lake monitoring must be carried out to evaluate the hazard of potential limnic or phreatic-magmatic eruptions. In Ecuador, two caldera lakesLakes Quilotoa and Cuicocha, located in the high Andean region >3000 a.s.l. – have been the focus of these investigations. Both volcanoes are geologically young or historically active, and have formed large and deep calderas with lakes of 2 to 3 km in diameter, and 248 and 148 m in depth, respectively. In both lakes, visible gas emissions of CO2 occur, and an accumulation of CO2 in the deep water body must be taken into account.

    Investigations were carried out to evaluate the hazards of these volcanic lakes, and in Lake Cuicocha intensive monitoring was carried out for the evaluation of possible renewed volcanic activities. At Lake Quilotoa, a limnic eruption and diffuse CO2 degassing at the lake surface are to be expected, while at Lake Cuicocha, an increased risk of a phreatic-magmatic eruption exists.

    This paper relates information concerning vocational courses in refrigeration in Quebec, with reference to the newly formed National Committee on Vocational and Technical Educational Programs. The aim of the paper was to collect data on the availability of refrigeration courses. A description of course outlines was provided, with reference to requirements in high school and at the college level. Requirement details for additional courses in heating and electricity refrigeration were also provided. The status of diplomas was also discussed, with reference to employment opportunities in management and analysis upon completion of the Diploma of Collegial Studies, which requires additional courses in energy conservation. Opportunities in the labour market were reviewed, as well as information on privately run courses. Particular reference was made concerning the Canadian Energy Technology Centre (CETC) as a leading research facility for refrigeration concepts and design. It was noted that very few courses on refrigeration technology are offered at the university level, and that currently only one distance education course on refrigeration has been recognized. As a result of this investigation, the Quebec Arena Association has determined that development of new courses is a priority, especially given that only the CETC currently offers courses on refrigeration for arenas and curling rinks. New courses should focus on arena and rink refrigeration technologies, with particular reference to new technologies and developments in energy efficiency. tabs., figs.

    1991-02-01

    Detailed geological investigations are under way at a number of liquefaction sites in the Ferland-Boilleau valley, Quebec, where sand boils, ground cracks and liquefaction-related damages to homes were documented immediately following the Ms=6.0, Mblg=6.5 Saguenay earthquake of November 25, 1988. To date, results obtained from these subsurface investigations of sand boils at two sites in Ferland, located about 26 km from the epicentre, indicate that: the Saguenay earthquake induced liquefaction in late-Pleistocene and Holocene sediments which was recorded as sand dikes, sills and vents in near-surface sediments and soils; earthquake-induced liquefaction and ground failure have occurred in this area at least three times in the past 10,000 years; and, the size and morphology of liquefaction features and the liquefaction susceptibility of source layers of the features may be indicative of the intensity of ground shaking. These preliminary results are very promising and suggest that with continued research liquefaction features will become a useful tool in glaciated terrains, such as northeastern North America, for determining not only the timing and location but also the size of past earthquakes

  11. Strategies for the development of Quebec`s petrochemical industry: education and environment

    Energy Technology Data Exchange (ETDEWEB)

    O`Connor, J.A. [Canadian Chemical Producer`s Association (Canada)

    1992-12-31

    One of the key challenges not only for the Quebec but for the Canadian petrochemical industry will be the challenge to increase the number of students pursuing science or engineering as fields of study. According to this author, there is a crisis in science and technology education in Canada. The ability of Canadian students to compete with their peers around the world is steadily diminishing as a result of the undue emphasis on student attitudes and self-esteem in Canadian schools, as opposed to European and Asian schools which focus on conveying specific skills. He advocates a shift in attitude away from simply more money spent on education towards concern with what and how well students are learning. It was suggested that the educational system must take into account the demands of the market place in fashioning the curricula. If students are to function in the real world where performance is evaluated, the educational system will have to change to reflect the fact that the market and society reward people in proportion to their contribution. The relationship between environmental concern and education was also explored, and the inclusion of environmental issues in the classroom curriculum was recommended. As a topic for curricula, the environment is subject to broad-ranging and often conflicting views regarding its problems and their causes, effects and remedies. Nevertheless, it is not a transient issue to be dismissed as a fad. Rather, it is an issue here to stay, hence it should play a more formalized role at all levels of the curriculum from primary schools to colleges and universities.

    Mercury and its compounds are present in the environment of northwest Quebec and present serious risks to human health. This study shows that all bodies of water investigated yield fish with mercury concentrations in excess of the Canadian safe limit (0.5 ppm) for human consumption. Data are reported for total mercury in 902 fishes from 58 bodies of water sampled between 1972 and 1976. Out of these, 158 were Coregonus clupeaformis with an average concentration of 0.27 ppm of mercury, 82 were Catostomus commersoni with 0.38 ppm, 287 were Stizostedion vitreum vitreum with 0.79 ppm, 364 were Esox lucius with 0.84 ppm, and 11 were Acipenser fulvescens with 0.36 ppm. It is concluded that walleye and pike are rarely safe to eat in northwest Quebec. Data on limited numbers of molluscs, benthic organisms, plankton, aquatic birds and aquatic mammals from this area are also reported and show only a few in excess of the safe level. Exceptions are found in ducks, grebes, mergansers and otters, mink and marten. Mercury in sediments varied from 50 ppb (background level) to more than 1000 ppb, depending on the body of water and its proximity to zones of influence of human activity. Surface waters rarely exceed 0.20 ppb mercury even in areas where sediment contamination is high. Ground water reached 48 ppb in some areas, however, suggesting contamination from natural sources.

    To determine how often primary health care providers (PHCPs) in family medicine groups (FMGs) assess physical activity (PA) levels, provide PA counseling (PAC), and refer patients to exercise professionals; to describe patients' PA levels, physical fitness, and satisfaction regarding their PA management in FMGs; to describe available PA materials in FMGs and PHCPs' PAC self-efficacy and PA knowledge; and to identify characteristics of patients and PHCPs that determine the assessment of PA and PAC provided by PHCPs. Cross-sectional study using questionnaires and a medical chart audit. Ten FMGs within the Integrated University Health Network of the Centre hospitalier universitaire de Sherbrooke in Quebec. Forty FPs, 24 nurses, and 439 patients. Assessment of PA level and PAC provided by PHCPs. Overall, 51.9% of the patients had had their PA level assessed during the past 18 months, but only 21.6% received PAC from at least 1 of the PHCPs. Similar percentages were found among the inactive (n = 244) and more active (n = 195) patients. The median PAC self-efficacy score of PHCPs was 70.2% (interquartile range 52.0% to 84.7%) and the median PA knowledge score was 45.8% (interquartile range 41.7% to 54.2%), with no significant differences between nurses and FPs. In multivariate analysis, 34% of the variance in PAC provided was explained by assessment of PA level, overweight or obese status, type 2 diabetes or prediabetes, less FP experience, lower patient annual family income, more nurse encounters, and a higher patient physical component summary of quality of life. The rates of assessment of PA and provision of PAC in Quebec FMGs were low, even though most of the patients were inactive. Initiatives to support PHCPs and more resources to assess PA levels and provide PAC should be implemented. Copyright© the College of Family Physicians of Canada.

    The objective was to assess trends in Inuit, First Nations and non-Aboriginal birth outcomes in the rural and northern regions of Quebec. In a birth cohort-based study of all births to residents of rural and northern Quebec from 1991 through 2000 (n = 177,193), we analyzed birth outcomes and infant mortality for births classified by maternal mother tongue (Inuit, First Nations or non-Aboriginal) and by community type (predominantly First Nations, Inuit or non-Aboriginal). From 1991-1995 to 1996-2000, there was a trend of increasing rates of preterm birth for all 6 study groups. In all rural and northern areas, low birth weight rates increased significantly only for the Inuit mother tongue group [RR1.45 (95% CI 1.05-2.01)]. Stillbirth rates showed a non-significant increase for the Inuit mother tongue group [RR1.76 (0.64-4.83)]. Neonatal mortality rates decreased significantly in the predominantly non-Aboriginal communities and in the non-Aboriginal mother tongue group [RR0.78 (0.66-0.92)], and increased non-significantly for the First Nations mother tongue group [RR2.17 (0.71-6.62)]. Perinatal death rates increased for the First Nations mother tongue grouping in northern areas [RR2.19 (0.99-4.85)]. There was a disconcerting rise of some mortality outcomes for births to First Nations and Inuit mother tongue women and to women in predominantly First Nations and Inuit communities, in contrast to some improvements for births to non-Aboriginal mother tongue women and to women in predominantly non-Aboriginal communities in rural or northern Quebec, indicating a need for improving perinatal and neonatal health for Aboriginal populations in rural and northern regions.

  18. Hydro-Quebec annual report, 1991

    Energy Technology Data Exchange (ETDEWEB)

    1991-01-01

    This annual report for the Quebec electric utility presents an overview of the year's activities and its financial status, including export sales of electricity to New Brunswick, Ontario, New York State, and the New England states. Research programs and demonstration projects are described, as well as the utility's activities in Africa and Asia. Environmental and economic considerations for the province are presented. Financial data includes total sales, sales by sector, export sales, and rate changes. A financial statement is included. In 1991, public controversy arose over electricity exports, risk-and-profit sharing contracts with some industrial customers, and the impacts of hydroelectric development. A net income of $760 million was achieved, representing an 88.1% increase over the previous year when exceptional measures were required to offset cumulative years of low runoff. These measures were suspended in late 1990 but low 1991 precipitation forced the continued purchase of backup electricity. Energy efficiency programs resulted in savings equivalent to energy consumed by a town of 13,000 people. Exports accounted for 7.2% of total sales in 1991. The first three generating units of LaGrande-2-A, totalling 999 MW, were commissioned. The groundwork has been laid for the vast corporate strategy of total customer satisfaction entitled Defi performance. In 1991, annual interruption time per customer dropped to 5.32 hours. 5 figs., 5 tabs.

    Full Text Available Cisco (Coregonus artedi is the most common coldwater stenothermal fish in Minnesota lakes. Water temperature (T and dissolved oxygen (DO in lakes are important controls of fish growth and reproduction and likely change with future climate warming. Built upon a previous study, this study uses a modified method to identify which of 620 cisco lakes in Minnesota can still support cisco populations under future climate and therefore be classified as cisco refuge lakes. The previous study used oxythermal stress parameter TDO3, the temperature at DO of 3 mg/L, simulated only from deep virtual lakes to classify 620 cisco lakes. Using four categories of virtual but representative cisco lakes in modified method, a one-dimensional water quality model MINLAKE2012 was used to simulate daily T and DO profiles in 82 virtual lakes under the past (1961–2008 and two future climate scenarios. A multiyear average of 31-day largest TDO3 over variable benchmark (VB periods, AvgATDO3VB, was calculated from simulated T and DO profiles using FishHabitat2013. Contour plots of AvgATDO3VB for four categories of virtual lakes were then developed to reclassify 620 cisco lakes into Tier 1 (AvgATDO3VB < 11 °C or Tier 2 refuge lakes, and Tier 3 non-refuge lakes (AvgATDO3VB > 17 °C. About 20% of 620 cisco lakes are projected to be refuge lakes under future climate scenarios, which is a more accurate projection (improving the prediction accuracy by ~6.5% from the previous study since AvgATDO3VB was found to vary by lake categories.

    Research on lake eutrophication often identifies variables affecting amounts of phosphorus (P) and nitrogen (N) in lakes, but understanding factors influencing N:P ratios is important given its influence on species composition and toxin production by cyanobacteria. We sampled 80 shallow lakes in Minnesota (USA) for three years to assess effects of watershed size, proportion of watershed as both row crop and natural area, fish biomass, and lake alternative state (turbid vs. clear) on total N : total P (TN : TP), ammonium, total dissolved phosphorus (TDP), and seston stoichiometry. We also examined N:P stoichiometry in 20 additional lakes that shifted states during the study. Last, we assessed the importance of denitrification by measuring denitrification rates in sediment cores from a subset of 34 lakes, and by measuring seston δ 15 N in four additional experimental lakes before and after they were experimentally manipulated from turbid to clear states. Results showed alternative state had the largest influence on overall N:P stoichiometry in these systems, as it had the strongest relationship with TN : TP, seston C:N:P, ammonium, and TDP. Turbid lakes had higher N at given levels of P than clear lakes, with TN and ammonium 2-fold and 1.4-fold higher in turbid lakes, respectively. In lakes that shifted states, TN was 3-fold higher in turbid lakes, while TP was only 2-fold higher, supporting the notion N is more responsive to state shifts than is P. Seston δ 15 N increased after lakes shifted to clear states, suggesting higher denitrification rates may be important for reducing N levels in clear states, and potential denitrification rates in sediment cores were among the highest recorded in the literature. Overall, our results indicate lake state was a primary driver of N:P dynamics in shallow lakes, and lakes in clear states had much lower N at a given level of P relative to turbid lakes, likely due to higher denitrification rates. Shallow lakes are often

    The Himalaya holds the world record in terms of range and elevation. It is one of the most extensively glacierized regions in the world except the Polar Regions. The Himalaya is a region sensitive to climate change. Changes in the glacial regime are indicators of global climate changes. Since the second half of the last century, most Himalayan glaciers have melted due to climate change. These changes directly affected the changes of glacial lakes in the Himalayan region due to the glacier retreat. New glacial lakes are formed, and a number of them have expanded in the Everest region of the Himalayas. This paper focuses on the two glacial lakes which are Imja Lake, located at the southern slope, and Rongbuk Lake, located at the northern slope in the Mt. Everest region, Himalaya to present the spatio-temporal changes from 1976 to 2008. Topographical conditions between two lakes were different (Kruskal-Wallis test, p < 0.05). Rongbuk Lake was located at 623 m higher than Imja Lake, and radiation of Rongbuk Lake was higher than the Imja Lake. Although size of Imja Lake was larger than the Rongbuk Lake in 2008, the growth speed of Rongbuk Lake was accelerating since 2000 and exceeds Imja Lake in 2000-2008. This trend of expansion of Rongbuk Lake is anticipated to be continued in the 21st century. Rongbuk Lake would be the biggest potential risk of glacial lake outburst flood (GLOF) at the Everest region of Himalaya in the future.

    The Great Lakes Science Center has conducted lake-wide bottom trawl surveys of the fish community in Lake Michigan each fall since 1973. These systematic surveys are performed at depths of 9 to 110 m at each of seven index sites around Lake Michigan. Zebra mussel (Dreissena polymorpha) populations have expanded to all survey locations and at a level to sufficiently contribute to the bottom trawl catches. The quagga (Dreissena bugensis), recently reported in Lake Michigan, was likely in the catches though not recognized. Dreissena spp. biomass ranged from about 0.6 to 15 kg/ha at the various sites in 1999. Dreissenid mussels were found at depths of 9 to 82 m, with their peak biomass at 27 to 46 m. The colonization of these exotic mussels has ecological implications as well as potential ramifications on the ability to sample fish consistently and effectively with bottom trawls in Lake Michigan.

    This paper presented details of new approaches to inflow forecast modelling developed by the Centre d'Expertise Hydrique du Quebec (CEHQ) as part its real-time decision-making management of Quebec public dams. The CEHQ now plans to include the impacts of quantitative precipitation and initial snow condition uncertainties within its program. In order to assess precipitation forecast uncertainties, distributions of errors using historical precipitation data and forecasted precipitation data were used. Conditional probabilities were then evaluated within the context of a special weather alert. A distributed hydrological model was used to simulate inflows that corresponded to various precipitation scenarios in order to determine a precipitation threshold which could be managed within dam outflow policies. The temporal evolution and spatial distribution of potential errors for basin snow water equivalent (SWE) were then studied separately. Outputs from a snow model were combined with tools from a geostatic model and used for error analysis. It was concluded that future research will focus on developing a strategy to incorporate SWE within the inflow forecasting model. 10 refs., 4 tabs., 5 figs.

    CO2 evasion from freshwater lakes is an important component of the carbon cycle. However, the relative contribution from different lake sizes may vary, since several parameters underlying CO2 flux are size dependent. Here we estimated the annual lake CO2 evasion from a catchment in northern Sweden encompassing about 30,000 differently sized lakes. We show that areal CO2 fluxes decreased rapidly with lake size, but this was counteracted by the greater overall coverage of larger lakes. As a result, total efflux increased with lake size and the single largest lake in the catchment dominated the CO2 evasion (53% of all CO2 evaded). By contrast, the contribution from the smallest ponds (about 27,000) was minor (evasion at the landscape scale.

    Proper lakes function can ease the impact of floods and drought especially in arid and semi-arid regions. They are important environmentally and can directly affect human lives. Better understanding of the effect of climate change and human-driven changes on lakes would provide invaluable information for policy-makers and local people. As part of a comprehensive study, we aim to monitor the land-cover/ land-use changes in the world's major lakes using satellite observations. As a case study, Hamun Lake which is a pluvial Lake, also known as shallow Lake, located on the south-east of Iran and adjacent to Afghanistan, and Pakistan borders is investigated. The Lake is the main source of resources (agriculture, fishing and hunting) for the people around it and politically important in the region since it is shared among three different countries. The purpose of the research is to find the Lake's area from 1972 to 2015 and to see if any drought or water resources management has affected the lake. Analyzing satellites imagery from Landsat shows that the area of the Lake changes seasonally and intra-annually. Significant seasonal effects are found in 1975,1977, 1987, 1993, 1996, 1998, 2000, 2009 and 2011, as well as, substantial amount of shallow water is found throughout the years. The precipitation records as well as drought historical records are studied for the lake's basin. Meteorological studies suggest that the drought, decrease of rainfalls in the province and the improper management of the Lake have caused environmental, economic and geographical consequences. The results reveal that lake has experienced at least two prolong dryings since 1972 which drought cannot solely be blamed as main forcing factor.Proper lakes function can ease the impact of floods and drought especially in arid and semi-arid regions.

    Full Text Available Legionella is found in natural and man-made aquatic environments, such as cooling towers and hot water plumbing infrastructures. Legionella pneumophila serogroup 1 (Lp1 is the most common etiological agent causing waterborne disease in the United States and Canada. This study reports the molecular characterization of Lp strains during a 10 year period. We conducted sequence-based typing (SBT analysis on a large set of Lp isolates (n = 284 to investigate the province of Quebec sequence types (STs distribution in order to identify dominant clusters. From 2005 to 2015, 181 clinical Lp isolates were typed by SBT (141 sporadic cases and 40 outbreak related cases. From the same period of time, 103 environmental isolates were also typed. Amongst the 108 sporadic cases of Lp1 typed, ST-62 was the most frequent (16.6%, followed by ST-213 (10.2%, ST-1 (8.3% and ST-37 (8.3%. Amongst other serogroups (SG, ST-1327 (SG5 (27.3% and ST-378 (SG10 (12.2% were the most frequent. From the environmental isolates, ST-1 represent the more frequent SBT type (26.5%. Unweighted pair group method with arithmetic mean (UPGMA dendrogram from the 108 sporadic cases of SG1 contains 4 major clusters (A to D of related STs. Cluster B contains the majority of the strains (n = 61 and the three most frequent STs in our database (ST-62, ST-213 and ST-1. During the study period, we observed an important increase in the incidence rate in Quebec. All the community associated outbreaks, potentially or confirmed to be associated with a cooling tower were caused by Lp1 strains, by opposition to hospital associated outbreaks that were caused by serogroups of Lp other than SG1. The recent major Quebec City outbreak caused by ST-62, and the fact that this genotype is the most common in the province supports whole genome sequencing characterization of this particular sequence type in order to understand its evolution and associated virulence factors.

    The snow cover (extent, depth and water equivalent) is an important factor in assessing the water balance of a territory. In a context of deregulation of electricity, better knowledge of the quantity of water resulting from snowmelt that will be available for hydroelectric power generation has become a major challenge for the managers of Hydro-Quebec's generating plant. In fact, the snow on the ground represents nearly one third of Hydro-Quebec's annual energy reserve and the proportion is even higher for northern watersheds. Snowcover knowledge would therefore help optimize the management of energy stocks. The issue is especially important when one considers that better management of water resources can lead to substantial economic benefits. The Research Institute of Hydro-Quebec (IREQ), our research partner, is currently attempting to optimize the streamfiow forecasts made by its hydrological models by improving the quality of the inputs. These include a parameter known as the snow water equivalent (SWE) which characterizes the properties of the snow cover. At the present time, SWE data is obtained from in situ measurements, which are both sporadic and scattered, and does not allow the temporal and spatial variability of SWE to be characterized adequately for the needs of hydrological models. This research project proposes to provide the Quebec utility's hydrological models with distributed SWE information about its northern watersheds. The targeted accuracy is 15% for the proposed period of analysis covering the winter months of January, February and March of 2001 to 2006. The methodology is based on the HUT snow emission model and uses the passive microwave remote sensing data acquired by the SSM/I sensor. Monitoring of the temporal and spatial variations in SWE is done by inversion of the model and benefits from the assimilation of in situ data to characterize the state of snow cover during the season. Experimental results show that the assimilation technique

    According to the Intergovernmental Panel on Climate Change (IPCC, 2007), an intensification of the global hydrological cycle and increase in precipitation for some regions around the world, including the northern mid- to high-latitudes, is expected in future climate. This will have an impact on mean and extreme flow characteristics, which need to be assessed for better development of adaptation strategies. Analysis of the mean and extreme streamflow characteristics for Quebec (North-eastern Canada) basins in current climate and their projected changes in future climate are assessed using a 10 member ensemble of current (1970 - 1999) and future (2041 - 2070) Canadian RCM (CRCM4) simulations. Validation of streamflow characteristics, performed by comparing modeled values with those observed, available from the Centre d'expertise hydrique du Quebec (CEHQ) shows that the model captures reasonably well the high flows. Results suggest increase in mean and 10 year return levels of 1 day high flows, which appear significant for most of the northern basins.

    2000-01-01

    We examined the relationship between environmental factors and the richness of submerged macrophytes species in 73 Danish lakes, which are mainly small, shallow, and have mesotrophic to hypertrophic conditions. We found that mean species richness per lake was only 4.5 in acid lakes of low...... alkalinity but 12.3 in lakes of high alkalinity due to a greater occurrence of the species-rich group of elodeids. Mean species richness per lake also increased significantly with increasing Secchi depth. No significant relationship between species richness and lake surface area was observed among the entire...... group of lakes or a subset of eutrophic lakes, as the growth of submerged macrophytes in large lakes may be restricted by wave action in shallow water and light restriction in deep water. In contrast, macrophyte species richness increased with lake surface area in transparent lakes, presumably due...

    A literature review on the incidence of different forms of child maltreatment revealed that rates in Australia and Quebec (Canada) were similar. This study sought to determine the prevalence and co-occurrence of various forms of violence (physical, sexual and psychological) and explore gender and age difference. A telephone inquiry was conducted with a representative sample of 1,002 adults from the province of Quebec. More than one in three adults (37%) reported having experienced at least one of three forms of violence in childhood. Twelve per cent (12%) of the adults experienced two forms of violence while 4% of the respondents reported having experienced all three forms of violence in childhood. Psychological violence (22%) was the form most frequently reported, followed by physical violence (19%) and sexual violence (16%). The different prevalence rates did not vary as a function of age. However, regarding gender, women were more likely to report having been sexually victimised (rape and fondling) and less likely to report having experienced physical violence. A lower percentage of women reported having sustained no form of childhood victimisation and a higher percentage of women reported have experienced both sexual and psychological violence compared to men. These results, including both the global rates and those particular to each gender, are comparable to findings in similar North American studies. The co-occurrence rates noted are salient enough to necessitate particular attention to diverse clinical clientele and need to be considered in future research exploring the risk factors of violence and its subsequent repercussions.

  19. LakeMIP Kivu: evaluating the representation of a large, deep tropical lake by a set of one-dimensional lake models

    Full Text Available The African great lakes are of utmost importance for the local economy (fishing, as well as being essential to the survival of the local people. During the past decades, these lakes experienced fast changes in ecosystem structure and functioning, and their future evolution is a major concern. In this study, for the first time a set of one-dimensional lake models are evaluated for Lake Kivu (2.28°S; 28.98°E, East Africa. The unique limnology of this meromictic lake, with the importance of salinity and subsurface springs in a tropical high-altitude climate, presents a worthy challenge to the seven models involved in the Lake Model Intercomparison Project (LakeMIP. Meteorological observations from two automatic weather stations are used to drive the models, whereas a unique dataset, containing over 150 temperature profiles recorded since 2002, is used to assess the model's performance. Simulations are performed over the freshwater layer only (60 m and over the average lake depth (240 m, since salinity increases with depth below 60 m in Lake Kivu and some lake models do not account for the influence of salinity upon lake stratification. All models are able to reproduce the mixing seasonality in Lake Kivu, as well as the magnitude and seasonal cycle of the lake enthalpy change. Differences between the models can be ascribed to variations in the treatment of the radiative forcing and the computation of the turbulent heat fluxes. Fluctuations in wind velocity and solar radiation explain inter-annual variability of observed water column temperatures. The good agreement between the deep simulations and the observed meromictic stratification also shows that a subset of models is able to account for the salinity- and geothermal-induced effects upon deep-water stratification. Finally, based on the strengths and weaknesses discerned in this study, an informed choice of a one-dimensional lake model for a given research purpose becomes possible.

    Thaw lakes in permafrost areas are sources of the strong greenhouse gas methane. They develop mostly in sedimentary lowlands with permafrost and a high excess ground ice volume, resulting in large areas covered with lakes and drained thaw-lake basins (DTLBs; refs,). Their expansion is enhanced by

    Eastern equine encephalitis virus (EEEV) is a highly pathogenic arbovirus that infects humans, horses, and other animals. There has been a significant increase in EEEV activity in southeastern Canada since 2008. Few data are available regarding nonlethal EEEV infections in mammals, and consequently the distribution and pathogenicity spectrum of EEEV infections in these hosts is poorly understood. This cross-sectional study focuses on the evaluation of viral activity in southern Quebec's horses by seroprevalence estimation. A total of 196 horses, 18 months and older, which had never been vaccinated against EEEV and have never traveled outside Canada, were sampled from 92 barns distributed throughout three administrative regions of southern Quebec. Blood samples were taken from each horse and titrated for EEEV antibodies by plaque reduction neutralization test (PRNT). Equine population vaccination coverage was estimated by surveying horse owners and equine practitioners. PRNT results revealed an EEEV seroprevalence up to 8.7%, with 95% confidence limits ranging from 4.4% to 13.0%. Vaccination coverage was estimated to be at least 79%. Our study reveals for the first time in Canada a measure of EEEV seroprevalence in horses. High seroprevalence in unvaccinated animals challenges the perception that EEEV is a highly lethal pathogen in horses. Monitoring high-risk vector-borne infections such as EEEV in animal populations can be an important element of a public health surveillance strategy, population risk assessment and early detection of epidemics.

    To create an easy-to-use dynamic database designed specifically for the Quebec Trophoblastic Disease Registry (RMTQ). It is now well established that much of the success in managing trophoblastic diseases comes from the development of national and regional reference centers. Computerized databases allow the optimal use of data stored in these centers. We have created an electronic data registration system by producing a database using FileMaker Pro 12. It uses 11 external tables associated with a unique identification number for each patient. Each table allows specific data to be recorded, incorporating demographics, diagnosis, automated staging, laboratory values, pathological diagnosis, and imaging parameters. From January 1, 2009, to December 31, 2013, we used our database to register 311 patients with 380 diseases and have seen a 39.2% increase in registrations each year between 2009 and 2012. This database allows the automatic generation of semilogarithmic curves, which take into account β-hCG values as a function of time, complete with graphic markers for applied treatments (chemotherapy, radiotherapy, or surgery). It generates a summary sheet for a synthetic vision in real time. We have created, at a low cost, an easy-to-use database specific to trophoblastic diseases that dynamically integrates staging and monitoring. We propose a 10-step procedure for a successful trophoblastic database. It improves patient care, research, and education on trophoblastic diseases in Quebec and leads to an opportunity for collaboration on a national Canadian registry.

    In this paper, a number of parameters of importance to a preliminary determination of the ecological function of lakes are presented. The choice of parameters have been made with respect to a model for the determination of the nature conservation values of lakes which is currently being developed by the authors of this report, but is also well suited for a general description of the lake type and the functioning of the inherent ecosystem. The parameters have been divided into five groups: (1) The location of the object relative important gradients in the surrounding nature; (2) The lake catchment area and its major constituents; (3) The lake morphometry; (4) The lake ecosystem; (5) Human-induced damages to the lake ecosystem. The first two groups, principally based on the climate, hydrology, geology and vegetation of the catchment area represent parameters that can be used to establish the rarity and representativity of the lake, and will in the context of site investigation program be used as a basis for generalisation of the results. The third group, the lake morphometry parameters, are standard parameters for the outline of sampling programmes and for calculations of the physical extension of different key habitats in the system. The fourth group, the ecosystem of the lake, includes physical, chemical and biological parameters required for determination of the stratification pattern, light climate, influence from the terrestrial ecosystem of the catchment area, trophic status, distribution of key habitats, and presence of fish and rare fauna and flora in the lake. In the context of site investigation program, the parameters in these two groups will be used for budget calculations of the flow of energy and material in the system. The fifth group, finally, describes the degree on anthropogenic influence on the ecosystem and will in the context of site investigation programmes be used to judge eventual malfunctioning within the entire, or parts of, the lake

    Rb-Sr whole-rock ages have been determined for rocks from the Oxford Lake-Knee Lake-Gods Lake geenstone belt in the Superior Province of northeastern Manitoba. The age of the Magill Lake Pluton is 2455 +- 35 Ma(lambda 87 Rb = 1.42 x 10 -11 yr -1 ), with an initial 87 Sr/ 86 Sr ratio of 0.7078 +- 0.0043. This granite stock intrudes the Oxford Lake Group, so it is post-tectonic and probably related to the second, weaker stage of metamorphism. The age of the Bayly Lake Pluton is 2424 +- 74 Ma, with an initial 87 Sr/ 86 Sr ratio of 0.7029 +- 0.0001. This granodioritic batholith complex does not intrude the Oxford Lake Group. It is syn-tectonic and metamorphosed. The age of volcanic rocks of the Hayes River Group, from Goose Lake (30 km south of Gods Lake Narrows), is 2680 +- 125 Ma, with an initial 87 Sr/ 86 Sr ratio of 0.7014 +- 0.0009. The age for the Magill Lake and Bayly Lake Plutons can be interpreted as the minimum ages of granite intrusion in the area. The age for the Hayes River Group volcanic rocks is consistent with Rb-Sr ages of volcanic rocks from other Archean greenstone belts within the northwestern Superior Province. (auth)

  9. Developing an ‘integrated health system’: the reform of health and social services in Quebec

    Levine, David

    2008-01-01

    The Quebec health care system, founded in 1970 as a public, single payer, state run system had by 2004 reached a turning point. Rising costs, working in silos, difficulty accessing physicians, increased waiting time for diagnostic imaging and surgical intervention led policy makers and politicians to propose a new model for the organisation and delivery of care. Based on populational responsibility and the clear distinction between a community primary care and specialised services a new model was proposed to develop integrated health networks. The 7.2 million population of Quebec was divided into 95 territories. 95 Health and social service centres were created by merging a community hospital, rehab centre, long-term care centres, home care and primary care services into a single institution with a new CEO and board of directors. These new networks received the mandate to manage the health and well being of their population, to manage the utilisation of services by their population and to manage all primary care services on their territory. The implementation of a chronic care model, the development of primary care multidisciplinary teams, empowering the population and performance management, are the key elements of Montreal's vision in implementing the Reform. After three years of operation the results are promising.

  10. A Dynamical Downscaling study over the Great Lakes Region Using WRF-Lake: Historical Simulation

    Xiao, C.; Lofgren, B. M.

    2014-12-01

    As the largest group of fresh water bodies on Earth, the Laurentian Great Lakes have significant influence on local and regional weather and climate through their unique physical features compared with the surrounding land. Due to the limited spatial resolution and computational efficiency of general circulation models (GCMs), the Great Lakes are geometrically ignored or idealized into several grid cells in GCMs. Thus, the nested regional climate modeling (RCM) technique, known as dynamical downscaling, serves as a feasible solution to fill the gap. The latest Weather Research and Forecasting model (WRF) is employed to dynamically downscale the historical simulation produced by the Geophysical Fluid Dynamics Laboratory-Coupled Model (GFDL-CM3) from 1970-2005. An updated lake scheme originated from the Community Land Model is implemented in the latest WRF version 3.6. It is a one-dimensional mass and energy balance scheme with 20-25 model layers, including up to 5 snow layers on the lake ice, 10 water layers, and 10 soil layers on the lake bottom. The lake scheme is used with actual lake points and lake depth. The preliminary results show that WRF-Lake model, with a fine horizontal resolution and realistic lake representation, provides significantly improved hydroclimates, in terms of lake surface temperature, annual cycle of precipitation, ice content, and lake-effect snowfall. Those improvements suggest that better resolution of the lakes and the mesoscale process of lake-atmosphere interaction are crucial to understanding the climate and climate change in the Great Lakes region.

    Little is known about DOM characteristics in medium to large sized lakes located in the middle and lower reaches of Yangtze River, like Lake Honghu, Lake Donghu and Lake Liangzihu. Absorption, fluorescence and composition characteristics of chromophoric dissolved organic matter (CDOM) are presented using the absorption spectroscopy, the excitation-emission ma trices (EEMs) fluorescence and parallel factor analysis (PARAFAC) model based on the data collected in Sep-Oct. 2007 including 15, 9 and 10 samplings in Lake Honghu, Lake Donghu and Lake Liangzihu, respectively. CDOM absorption coefficient at 350 nm a(350) coefficient in Lake Honghu was significantly higher than those in Lake Donghu and Lake Liangzihu (t-test, pCDOM spectral slope in the wavelength range of 280-500 nm (S280-500) and a(350) (R2 =0. 781, p<0. 001). The mean value of S280-500 in Lake Honghu was significantly lower than those in Lake Donghu (t-test, pLake Liangzihu (t-test, p<0. 001). The mean value of spectral slope ratio SR in Lake Honghu was also significantly lower than those in Lake Donghu and Lake Liangzihu (t-test, p<0. 05). Two humic-like (C1, C2) and two protein-like fluorescent components (C3, C4) were identified by PARAFAC model, among which significant positive correlations were found between C1 and C2 (R2 =0. 884, p<0. 001), C3 and C4 (R2 =0. 677, p<0.001), respectively, suggesting that the sources of the two humic-like components as well as the two protein-like components were similar. However, no significant correlation has been found between those 4 fluorescent components and DOC concentration. Th e fluorescenceindices of FI255 (HIX), Fl265, FI310 (BIX) and Fl370 in Lake Donghu were all significantly higher than those in Lake Liangzihu (t-test, p <0.05) and Lake Honghu (t-test, p<0. 01), indicating that the eutrophication status in Lake Donghu was higher than Lake Honghu and Lake Liangzihu.

    2014-01-01

    This paper presents a relevant approach to predict the indoor radon potential based on the combination of the radiogeochemical data and the indoor radon measurements in the Quebec province territory (Canada). The Quebec ministry of health asked for such a map to identify the radon-prone areas to manage the risk for the population related to indoor radon exposure. Three radiogeochemical criteria including (1) equivalent uranium (eU) concentration from airborne surface gamma-ray surveys, (2) uranium concentration measurements in sediments, (3) bedrock and surficial geology were combined with 3082 basement radon concentration measurements to identify the radon-prone areas. It was shown that it is possible to determine thresholds for the three criteria that implied statistically significant different levels of radon potential using Kruskal–Wallis one way analyses of variance by ranks. The three discretized radiogeochemical datasets were combined into a total predicted radon potential that sampled 98% of the studied area. The combination process was also based on Kruskal–Wallis one way ANOVA. Four statistically significant different predicted radon potential levels were created: low, medium, high and very high. Respectively 10 and 13% of the dwellings exceed the Canadian radon guideline of 200 Bq/m 3 in low and medium predicted radon potentials. These proportions rise up to 22 and 45% respectively for high and very high predicted radon potentials. This predictive map of indoor radon potential based on the radiogeochemical data was validated using a map of confirmed radon exposure in homes based on the basement radon measurements. It was shown that the map of predicted radon potential based on the radiogeochemical data was reliable to identify radon-prone areas even in zones where no indoor radon measurement exists. - Highlights: • 5 radiogeochemical datasets were used to map the geogenic indoor radon potential. • An indoor radon potential was determined for each

    The deglacial history of the Lake Michigan basin, including discharge and routing of meltwater, is complex because of the interaction among (1) glacial retreats and re-advances in the basin (2) the timing of occupation and the isostatic adjustment of lake outlets and (3) the depositional and erosional processes that left evidence of past lake levels. In the southern part of the basin, a restricted area little affected by differential isostasy, new studies of onshore and offshore areas allow refinement of a lake-level history that has evolved over 100 years. Important new data include the recognition of two periods of influx of meltwater from Lake Agassiz into the basin and details of the highstands gleaned from sedimentological evidence. Major disagreements still persist concerning the exact timing and lake-level changes associated with the Algonquin phase, approximately 11,000 BP. A wide variety of independent data suggests that the Lake Michigan Lobe was thin, unstable, and subject to rapid advances and retreats. Consequently, lake-level changes were commonly abrupt and stable shorelines were short-lived. The long-held beliefs that the southern part of the basin was stable and separated from deformed northern areas by a hinge-line discontinuity are becoming difficult to maintain. Numerical modeling of the ice-earth system and empirical modeling of shoreline deformation are both consistent with observed shoreline tilting in the north and with the amount and pattern of modern deformation shown by lake-level gauges. New studies of subaerial lacustrine features suggest the presence of deformed shorelines higher than those originally ascribed to the supposed horizontal Glenwood level. Finally, the Lake Michigan region as a whole appears to behave in a similar manner to other areas, both local (other Great Lakes) and regional (U.S. east coast), that have experienced major isostatic changes.

    The Great Lakes region, as defined here, includes the Great Lakes and their drainage basins in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, and New York. The region also includes the portions of Minnesota, Wisconsin, and the 21 northernmost counties of Illinois that lie in the Mississippi River drainage basin, outside the floodplain of the river. The region spans about 9º of latitude and 20º of longitude and lies roughly halfway between the equator and the North Pole in a lowland corridor that extends from the Gulf of Mexico to the Arctic Ocean.The Great Lakes are the most prominent natural feature of the region (Fig. 1). They have a combined surface area of about 245,000 square kilometers and are among the largest, deepest lakes in the world. They are the largest single aggregation of fresh water on the planet (excluding the polar ice caps) and are the only glacial feature on Earth visible from the surface of the moon (The Nature Conservancy 1994a).The Great Lakes moderate the region’s climate, which presently ranges from subarctic in the north to humid continental warm in the south (Fig. 2), reflecting the movement of major weather masses from the north and south (U.S. Department of the Interior 1970; Eichenlaub 1979). The lakes act as heat sinks in summer and heat sources in winter and are major reservoirs that help humidify much of the region. They also create local precipitation belts in areas where air masses are pushed across the lakes by prevailing winds, pick up moisture from the lake surface, and then drop that moisture over land on the other side of the lake. The mean annual frost-free period—a general measure of the growing-season length for plants and some cold-blooded animals—varies from 60 days at higher elevations in the north to 160 days in lakeshore areas in the south. The climate influences the general distribution of wild plants and animals in the region and also influences the activities and distribution of the human

    The diversity of terrestrial systems is estimated to be greater than in the marine realm. However no hard data yet exists to substantiate this claim. Ancient lacustrine deposits may preserve an exceptionally diverse fossil fauna and aid in determining continental faunal diversities. Fossils preserved in lake deposits, especially those with exceptional preservation (i.e. Konservat Lagerstaetten), may represent a dependable method for determining species diversity changes in the terrestrial environment because of their faunal completeness. Important Konservat Lagerstaetten, such as the Green River Formation (US) and Messel (Germany), both Eocene in age, are found in lake sediments and show a remarkable faunal diversity for both vertebrates and invertebrates. To date information from nearly 25 lake lagerstaetten derived from different types of lake basins from the Carboniferous to the Miocene have been collected and described. Carboniferous sites derive from the cyclothems of Midcontinent of the US while many Cenozoic sites have been described from North and South America as well as Europe and Australia. Asian sites contain fossils from the Mesozoic and Cenozoic. With this data, insight into the evolutionary processes associated with lake systems can be examined. Do lakes act as unique evolutionary crucibles in contrast to marine systems? The speciation of cichlid fishes in present-day African lakes appears to be very high and is attributed to the diversity of environments found in large rift lakes. Is this true of all ancient lakes or just large rift lakes? The longevity of a lake system may be an important factor in allowing speciation and evolutionary processes to occur; marine systems are limited only in the existence of environments as controlled by tectonics and sea level changes, on the order of tens of millions of years. Rift lakes are normally the longest lived in the millions of years. Perhaps there are only certain types of lakes in which speciation of

    The Fox Chain of Lakes is a glacial lake system in McHenry and Lake Counties in northern Illinois and southern Wisconsin. Sedimentation and nutrient overloading have occurred in the lake system since the first dam was built (1907) in McHenry to raise water levels in the lake system. Using data collected from December 1, 1997, to June 1, 1999, suspended-sediment budgets were constructed for the most upstream lake in the system, Grass Lake, and for the lakes downstream from Grass Lake. A total of 64,900 tons of suspended sediment entered Grass Lake during the study, whereas a total of 70,600 tons of suspended sediment exited the lake, indicating a net scour of 5,700 tons of sediment. A total of 44,100 tons of suspended sediment was measured exiting the Fox Chain of Lakes at Johnsburg, whereas 85,600 tons entered the system downstream from Grass Lake. These suspended-sediment loads indicate a net deposition of 41,500 tons downstream from Grass Lake, which represents a trapping efficiency of 48.5 percent. A large amount of recreational boating takes place on the Fox Chain of Lakes during summer months, and suspended-sediment load was observed to rise from 110 tons per day to 339 tons per day during the 1999 Memorial Day weekend (May 26 ?31, 1999). Presumably, this rise was the result of the boating traffic because no other hydrologic event is known to have occurred that might have caused the rise. This study covers a relatively short period and may not represent the long-term processes of the Fox Chain of Lakes system, although the sediment transport was probably higher than an average year. The bed sediments found on the bottom of the lakes are composed of mainly fine particles in the silt-clay range. The Grass Lake sediments were characterized as black peat with an organic content of between 9 and 18 percent, and the median particle size ranged from 0.000811 to 0.0013976 inches. Other bed material samples were collected at streamflow-gaging stations on the

    Full Text Available The English-speaking Canada and the rebellious Frenchspeaking «province» of Quebec are going through a broad and deep identity crisis that dates back to the 19th century, but intensified in the new age of globalization. A country created by immigration, it is still a country of immigration and one of the most multiethnic countries in the world. Multiculturalism is the model of political management that belongs to this diversity and the ideology that legitimates it —a Canadian inventio— at the same time that it recognizes, ignores and eludes the internal conflict —the Canada-Quebec conflict— that implicitly determines the differentiated migratory policies of both political communities. On its part, Quebequian multiculturalism («interculturalism» shows two different models (pro-assimilation and pro differentiation. These tensions, ambiguities, and diversity of models shape the current Canadian and Quebequian debate about citizenship, which conditions and functions as a frame of reference for social work (professional social intervention with immigrants, very developed both in theory and in practice in this American country, and that is aware of the political challenges offered by multiculturalism in Ottawa and Quebec. The study and evaluation of this dynamic reality can be extremely useful in Europe, both North and South, for working out public policies and organizing social work in a multiethnic environment.

    2008-03-01

    A method is presented to assess lake water-groundwater interactions by modelling isotope signatures of lake water using meteorological parameters and field data. The modelling of delta(18)O and deltaD variations offers information about the groundwater influx into a meromictic Lusatian mining lake. Therefore, a water balance model is combined with an isotope water balance model to estimate analogies between simulated and measured isotope signatures within the lake water body. The model is operated with different evaporation rates to predict delta(18)O and deltaD values in a lake that is only controlled by weather conditions with neither groundwater inflow nor outflow. Comparisons between modelled and measured isotope values show whether the lake is fed by the groundwater or not. Furthermore, our investigations show that an adaptation of the Craig and Gordon model [H. Craig, L.I. Gordon. Deuterium and oxygen-18 variations in the ocean and the marine atmosphere. In Stable Isotopes in Oceanographic Studies and Paleotemperature, Spoleto, E. Tongiorgi (Ed.), pp. 9-130, Consiglio Nazionale delle Ricerche, Laboratorio di Geologia Nucleare, Pisa (1965).] to specific conditions in temperate regions seems necessary.

    Rainy Lake, Minnesota-Ontario, contains a native population of Lake Sturgeon (Acipenser fulvescens) that has gone largely unstudied. The objective of this descriptive study was to summarize generalized Lake Sturgeon movement patterns through the use of biotelemetry. Telemetry data reinforced the high utilization of the Squirrel Falls geographic location by Lake Sturgeon, with 37% of the re-locations occurring in that area. Other spring aggregations occurred in areas associated with Kettle Falls, the Pipestone River, and the Rat River, which could indicate spawning activity. Movement of Lake Sturgeon between the Seine River and the South Arm of Rainy Lake indicates the likelihood of one integrated population on the east end of the South Arm. The lack of re-locations in the Seine River during the months of September and October may have been due to Lake Sturgeon moving into deeper water areas of the Seine River and out of the range of radio telemetry gear or simply moving back into the South Arm. Due to the movements between Minnesota and Ontario, coordination of management efforts among provincial, state, and federal agencies will be important.

    A tuning method for FLake, a one-dimensional (1-D) freshwater lake model, is applied for the individual tuning of 244 globally distributed large lakes using observed lake surface water temperatures (LSWTs) derived from along-track scanning radiometers (ATSRs). The model, which was tuned using only three lake properties (lake depth, snow and ice albedo and light extinction coefficient), substantially improves the measured mean differences in various features of the LSWT annual cycle, including the LSWTs of saline and high altitude lakes, when compared to the observed LSWTs. Lakes whose lake-mean LSWT persists below 1 °C for part of the annual cycle are considered to be seasonally ice-covered. For trial seasonally ice-covered lakes (21 lakes), the daily mean and standard deviation (2σ) of absolute differences between the modelled and observed LSWTs are reduced from 3.07 °C ± 2.25 °C to 0.84 °C ± 0.51 °C by tuning the model. For all other trial lakes (14 non-ice-covered lakes), the improvement is from 3.55 °C ± 3.20 °C to 0.96 °C ± 0.63 °C. The post tuning results for the 35 trial lakes (21 seasonally ice-covered lakes and 14 non-ice-covered lakes) are highly representative of the post-tuning results of the 244 lakes. For the 21 seasonally ice-covered lakes, the modelled response of the summer LSWTs to changes in snow and ice albedo is found to be statistically related to lake depth and latitude, which together explain 0.50 (R2adj, p = 0.001) of the inter-lake variance in summer LSWTs. Lake depth alone explains 0.35 (p = 0.003) of the variance. Lake characteristic information (snow and ice albedo and light extinction coefficient) is not available for many lakes. The approach taken to tune the model, bypasses the need to acquire detailed lake characteristic values. Furthermore, the tuned values for lake depth, snow and ice albedo and light extinction coefficient for the 244 lakes provide some guidance on improving FLake LSWT modelling.

    Full Text Available The Program of Research to Integrate the Services for the Maintenance of Autonomy (PRISMA began in Quebec in 1999. Evaluation results indicated that the PRISMA Project improved the system of care for the frail elderly at no additional cost. In 2001, the Quebec Ministry of Health and Social Services made implementing the six features of the PRISMA approach a province-wide goal in the programme now known as RSIPA (French acronym. Extensive Province-wide progress has been made since then, but ongoing challenges include reducing unmet need for case management and home care services, creating incentives for increased physician participation in care planning and improving the computerized client chart, among others. PRISMA is the only evaluated international model of a coordination approach to integration and one of the few, if not the only, integration model to have been adopted at the system level by policy-makers.

    Highlights: ? We transferred freshwater bivalves from a reference lake to a Cd and Zn contaminated lake. ? Changes in metal accumulation and subcellular partitioning were followed over time (up to 860 d). ? Metal detoxification strategies differed between target organs (gills vs. digestive gland). ? The ability to handle Cd is inherent in P. grandis, not a trait acquired after long-term adaptation. -- Abstract: The objective of the present field experiment was to identify detoxification responses in the gills and digestive gland of a freshwater unionid bivalve, Pyganodon grandis, subjected to a step-change in metal exposure. Adult bivalves were transferred from a reference site (Lake Opasatica) and a metal-contaminated lake (Lake Héva) to a second contaminated lake (Lake Vaudray) in northwestern Quebec, Canada. Changes in organ metal concentrations, in the subcellular distribution of metals and in metallothionein concentrations were followed over time (t = 0, 132, (400) and 860 days). At each collection time and for each bivalve, the gills and digestive gland were excised and gently homogenized; six sub-cellular fractions were separated by differential centrifugation and analyzed for their Cd, Cu and Zn content, and metallothionein was quantified independently. Metal detoxification strategies were shown to differ between target organs: in the gills, incoming metals were sequestered largely in the granules, whereas in the digestive gland the same metals primarily accumulated in the cytosol, in the metallothionein-like protein fraction. These metal-handling strategies, as employed by the metal-naïve bivalves originating in the reference lake, closely resemble those identified in free-living P. grandis chronically exposed in the metal-contaminated lake, suggesting that the ability to handle incoming metals (Cd in particular) is inherent in P. grandis and is not a trait acquired after long-term adaptation of the bivalve to metal-contaminated environments.

    A compilation is presented of the sums invested in 1991 and the projected investments for 1992 in the Quebec energy sector. Historical data back to 1982 are also included. In 1991, the total investment rose to $4,328 million, or 27% more than in 1990. The year 1992 is expected to see a more modest 9% increase in energy investments. The relative value of energy investments compared to total Quebec investments was 15.6% in 1991 and is forecast to attain 16.9% in 1992. The large increase in energy investment is largely due to investments in the electric power sector, which receives ca 93% of Quebec energy investment. In the petroleum sector, preliminary data indicate that total investment in 1991 and 1992 will be $192.5 million and $203.1 million respectively, mostly for refining and distribution. In the natural gas sector, the historical data show a large peak at 1983 of $424 million, descending to the $50-70 million level starting in 1987. Natural gas investments in 1991 rose to $101.6 million, most of which went towards extending the distribution network. For 1992, $68.5 million is forecast to be invested. In the electric power sector, total 1991 investment was ca $4 billion, a 29% increase over 1990; 1992 investment is forecast at $4.46 billion. In 1991, the investment in electricity production totalled ca $2 billion and investment in power transmission $970 million, the latter mainly dedicated to construction of a 450 kV dc power line and to a network improvement program. Investment in power distribution was $567 million, while other investments such as communications, buildings, and technological activities amounted to $450 million. 4 figs., 5 tabs

    Full Text Available

    In the past, variations in the chemical contents (SO42−, Cl−, cations of crater lake water have not systematically demonstrated any relationships with eruptive activity. Intensive parameters (i.e., concentrations, temperature, pH, salinity should be converted into extensive parameters (i.e., fluxes, changes with time of mass and solutes, taking into account all the internal and external chemical–physical factors that affect the crater lake system. This study presents a generalized box model approach that can be useful for geochemical monitoring of active crater lakes, as highly dynamic natural systems. The mass budget of a lake is based on observations of physical variations over a certain period of time: lake volume (level, surface area, lake water temperature, meteorological precipitation, air humidity, wind velocity, input of spring water, and overflow of the lake. This first approach leads to quantification of the input and output fluxes that contribute to the actual crater lake volume. Estimating the input flux of the "volcanic" fluid (Qf- kg/s –– an unmeasurable subsurface parameter –– and tracing its variations with time is the major focus during crater lake monitoring. Through expanding the mass budget into an isotope and chemical budget of the lake, the box model helps to qualitatively characterize the fluids involved. The (calculated Cl− content and dD ratio of the rising "volcanic" fluid defines its origin. With reference to continuous monitoring of crater lakes, the present study provides tips that allow better calculation of Qf in the future. At present, this study offers the most comprehensive and up-to-date literature review on active crater lakes.

    2017-05-25

    IntroductionThe U.S. Geological Survey (USGS), in cooperation with local and other agencies, collects data at selected lakes throughout Wisconsin. These data, accumulated over many years, provide a database for developing an improved understanding of the water quality of lakes. To make these data available to interested parties outside the USGS, the data are published annually in this report series. The locations of water-quality and lake-stage stations in Wisconsin for water year 2014 are shown in figure 1. A water year is the 12-month period from October 1 through September 30. It is designated by the calendar year in which it ends. Thus, the periodOctober 1, 2013, through September 30, 2014, is called “water year 2014.”The purpose of this report is to provide information about the chemical and physical characteristics of Wisconsin lakes. Data that have been collected at specific lakes, and information to aid in the interpretation of those data, are included in this report. Data collected include measurements of in-lake water quality and lake stage. Time series of Secchi depths, surface total phosphorus, and chlorophyll a concentrations collected during nonfrozen periods are included for many lakes. Graphs of vertical profiles of temperature, dissolved oxygen, pH, and specific conductance are included for sites where these parameters were measured. Descriptive information for each lake includes the location of the lake, area of the lake’s watershed, period for which data are available, revisions to previously published records, and pertinent remarks. Additional data, such as streamflow and water quality in tributary and outlet streams of some of the lakes, are published online at http://nwis.waterdata.usgs.gov/wi/nwis.Water-resources data, including stage and discharge data at most streamflow-gaging stations, are available online.

    We assessed temporal trend in the incidence and prevalence of genital warts (GWs) in the province of Quebec, Canada, between 1998 and 2007 as a baseline for future assessment of the impact of Quebec human papillomavirus vaccination program. Data on GWs were obtained from the linkage of the physician service claims and the public insurance drug plan databases. Genital warts were identified through a prescription of podofilox, a medical procedure code specific to GWs or a diagnosis code for viral warts followed by a prescription of imiquimod or fluorouracil within 2 weeks. An episode was considered incident if it was preceded by a 12-month interval period free of GWs care. During the study period, a total of 27,138 episodes of GWs occurred among 24,267 individuals. The age-standardized incidence rate increased over time in men and women. The highest incidence was observed in women aged 20 to 24 years (391.9/100,000) and in men aged 25 to 29 years (383.3/100,000). Similar trends in prevalence were observed. The incidence and prevalence of GWs has increased among the population covered by the public insurance drug plan in Quebec.

The cadmium levels in the ptarmigan were below the threshold above which adverse effects can be observed in birds. The difference between the two ptarmigan species in cadmium content is explained by the diet. A comparison of their diet showed that willow, which stores cadmium, is an important food resource for willow ptarmigan but not for rock ptarmigan.

  13. Simulating Lake-Groundwater Interactions During Decadal Climate Cycles: Accounting For Variable Lake Area In The Watershed

    2009-12-01

    The volume and extent of a lake within the topo-bathymetry of a watershed can change substantially during wetter and drier climate cycles, altering the interaction of the lake with the groundwater flow system. Lake Starr and other seepage lakes in the permeable sandhills of central Florida are vulnerable to climate changes as they rely exclusively on rainfall and groundwater for inflows in a setting where annual rainfall and recharge vary widely. The groundwater inflow typically arrives from a small catchment area bordering the lake. The sinkhole origin of these lakes combined with groundwater pumping from underlying aquifers further complicate groundwater interactions. Understanding the lake-groundwater interactions and their effects on lake stage over multi-decadal climate cycles is needed to manage groundwater pumping and public expectation about future lake levels. The interdependence between climate, recharge, changing lake area and the groundwater catchment pose unique challenges to simulating lake-groundwater interactions. During the 10-year study period, Lake Starr stage fluctuated more than 13 feet and the lake surface area receded and expanded from 96 acres to 148 acres over drier and wetter years that included hurricanes, two El Nino events and a La Nina event. The recently developed Unsaturated Zone Flow (UZF1) and Lake (LAK7) packages for MODFLOW-2005 were used to simulate the changing lake sizes and the extent of the groundwater catchment contributing flow to the lake. The lake area was discretized to occupy the largest surface area at the highest observed stage and then allowed to change size. Lake cells convert to land cells and receive infiltration as receding lake area exposes the underlying unsaturated zone to rainfall and recharge. The unique model conceptualization also made it possible to capture the dynamic size of the groundwater catchment contributing to lake inflows, as the surface area and volume of the lake changed during the study

    A team of Texas AgriLife Research, Baylor University and University of Texas at Arlington researchers studied the biology and ecology of Prymnesium parvum (golden algae) in Texas lakes using a three-fold approach that involved system-wide monitoring, experimentation at the microcosm and mesocosm scales, and mathematical modeling. The following are conclusions, to date, regarding this organism's ecology and potential strategies for mitigation of blooms by this organism. In-lake monitoring revealed that golden algae are present throughout the year, even in lakes where blooms do not occur. Compilation of our field monitoring data with data collected by Texas Parks and Wildlife and Brazos River Authority (a period spanning a decade) revealed that inflow and salinity variables affect bloom formations. Thresholds for algae populations vary per lake, likely due to adaptations to local conditions, and also to variations in lake-basin morphometry, especially the presence of coves that may serve as hydraulic storage zones for P. parvum populations. More specifically, our in-lake monitoring showed that the highly toxic bloom that occurred in Lake Granbury in the winter of 2006/2007 was eliminated by increased river inflow events. The bloom was flushed from the system. The lower salinities that resulted contributed to golden algae not blooming in the following years. However, flushing is not an absolute requirement for bloom termination. Laboratory experiments have shown that growth of golden algae can occur at salinities ~1-2 psu but only when temperatures are also low. This helps to explain why blooms are possible during winter months in Texas lakes. Our in-lake experiments in Lake Whitney and Lake Waco, as well as our laboratory experiments, revealed that cyanobacteria, or some other bacteria capable of producing algicides, were able to prevent golden algae from blooming. Identification of this organism is a high priority as it may be a key to managing golden algae

    Reich, Christopher; Flocks, James; Davis, Jeffrey

    2012-01-01

    This study was initiated in cooperation with the St. Johns River Water Management District (SJRWMD) to investigate groundwater and surface-water interaction in designated sentinel lakes in central Florida. Sentinel lakes are a SJRWMD established set of priority water bodies (lakes) for which minimum flows and levels (MFLs) are determined. Understanding both the structure and lithology beneath these lakes can ultimately lead to a better understanding of the MFLs and why water levels fluctuate in certain lakes more so than in other lakes. These sentinel lakes have become important water bodies to use as water-fluctuation indicators in the SJRWMD Minimum Flows and Levels program and will be used to define long-term hydrologic and ecologic performance measures. Geologic control on lake hydrology remains poorly understood in this study area. Therefore, the U.S. Geological Survey investigated 16 of the 21 water bodies on the SJRWMD priority list. Geologic information was obtained by the tandem use of high-resolution seismic profiling (HRSP) and direct-current (DC) resistivity profiling to isolate both the geologic framework (structure) and composition (lithology). Previous HRSP surveys from various lakes in the study area have been successful in identifying karst features, such as subsidence sinkholes. However, by using this method only, it is difficult to image highly irregular or chaotic surfaces, such as collapse sinkholes. Resistivity profiling was used to complement HRSP by detecting porosity change within fractured or collapsed structures and increase the ability to fully characterize the subsurface. Lake Saunders (Lake County) is an example of a lake composed of a series of north-south-trending sinkholes that have joined to form one lake body. HRSP shows surface depressions and deformation in the substrate. Resistivity data likewise show areas in the southern part of the lake where resistivity shifts abruptly from approximately 400 ohm meters (ohm-m) along the

    The paraoxonase gene cluster on chromosome 7 comprising the PON1-3 genes is an attractive candidate for association in amyotrophic lateral sclerosis (ALS) given the role of paraoxonase genes during the response to oxidative stress and their contribution to the enzymatic break down of nerve toxins. Oxidative stress is considered one of the mechanisms involved in ALS pathogenesis. Evidence for this includes the fact that mutations of SOD1, which normally reduce the production of toxic superoxide anion, account for 12% to 23% of familial cases in ALS. In addition, PON variants were shown to be associated with susceptibility to ALS in several North American and European populations. We extended this analysis to examine 20 single nucleotide polymorphisms (SNPs) across the PON gene cluster in a set of patients from France (480 cases, 475 controls), Quebec (159 cases, 95 controls), and Sweden (558 cases, 506 controls). Although individual SNPs were not considered associated on their own, a haplotype of SNPs at the C-terminal portion of PON2 that includes the PON2 C311S amino acid change was significant in the French (p value 0.0075) and Quebec (p value 0.026) populations as well as all three populations combined (p value 1.69 x 10(-6)). Stratification of the samples showed that this variation was pertinent to ALS susceptibility as a whole, and not to a particular subset of patients. These findings contribute to the increasing weight of evidence that genetic variants in the paraoxonase gene cluster are associated with amyotrophic lateral sclerosis.

    Alcohol and drug use is a serious health problem for many indigenous populations across Canada, including Inuit. The literature on substance use in these populations is too sparse to devise public health interventions. The present article portrays alcohol and drug use among Inuit living in Nunavik (Northern Quebec) between the 1990s and 2000s, and identifies socio-demographic characteristics related to substance use. The Santé Québec Health Survey (1992) and the Nunavik Inuit Health Survey Qanuippitaa (2004) served as databases for this empirical work. Statistical comparisons were made of substance use variables in the 2 samples. Proportions were compared by chi-square tests (p≤0.05) with benchmarking of statistics for all of Quebec and, when available, all of Canada. Alcohol and drug use among Inuit increased significantly between 1992 and 2004, particularly among young adults. Alcohol users consumed significantly more alcohol per drinking episode than other Canadians in both time periods. Considerable cannabis use was widespread. In 2004, no significant differences in frequencies of heavy drinking episodes were observed by gender, with 60% of drug users consuming alcohol on a regular basis. As in other populations from North America, this study profiles the increase in substance use among Inuit from Nunavik in the first part of the last 20 years. We observed distinct substance use patterns among them in comparison to other Canadians. Such findings, if replicated in the coming years, emphasize the need for major, culturally-relevant public health interventions in this population.

    Lakes Superior, Huron, Michigan, Ontario, and Erie together form North America's Great Lakes, a region that contains 20% of the world's fresh surface water and is home to roughly one quarter of the U.S. population (Figure 1). Supporting a $4 billion sport fishing industry, plus $16 billion annually in boating, 1.5 million U.S. jobs, and $62 billion in annual wages directly, the Great Lakes form the backbone of a regional economy that is vital to the United States as a whole (see http://www.miseagrant.umich.edu/downloads/economy/11-708-Great-Lakes-Jobs.pdf). Yet the grandeur and importance of this freshwater resource are little understood, not only by people in the rest of the country but also by many in the region itself. To help address this lack of knowledge, the Centers for Ocean Sciences Education Excellence (COSEE) Great Lakes, supported by the U.S. National Science Foundation and the National Oceanic and Atmospheric Administration, developed literacy principles for the Great Lakes to serve as a guide for education of students and the public. These “Great Lakes Literacy Principles” represent an understanding of the Great Lakes' influences on society and society's influences on the Great Lakes.

    Because of growing concern in the Great Lakes over declines in abundance and growth of lake whitefish (Coregonus clupeaformis) and declines in abundance of the benthic amphipod Diporeia spp., a workshop was held to examine past and current trends, to explore trophic links, and to discuss the latest research results and needs. The workshop was divided into sessions on the status of populations in each of the lakes, bioenergetics and trophic dynamics, and exploitation and management. Abundance, growth, and condition of whitefish populations in Lakes Superior and Erie are stable and within the range of historical means, but these variables are declining in Lakes Michigan and Ontario and parts of Lake Huron. The loss of Diporeia spp., a major food item of whitefish, has been a factor in observed declines, particularly in Lake Ontario, but density-dependent factors also likely played a role in Lakes Michigan and Huron. The loss of Diporeia spp. is temporally linked to the introduction and proliferation of dreissenid mussels, but a direct cause for the negative response of Diporeia spp. has not been established. Given changes in whitefish populations, age-structured models need to be re-evaluated. Other whitefish research needs to include a better understanding of what environmental conditions lead to strong year-classes, improved aging techniques, and better information on individual population (stock) structure. Further collaborations between assessment biologists and researchers studying the lower food web would enhance an understanding of links between trophic levels.

  3. The Evolution of Beliefs and Opinions on Matters related to Marriage and Sexual Behaviour among French-speaking Catholic Quebecers and English-speaking Protestant Ontarians

    Full Text Available The authors argue that the important changes in behaviour related to family and sexual life that were seen in Quebec during the second half of the 20th century are a consequence of a major transformation of the foundation of the normative system shared by the members of Quebec’s main socio-religious group, Frenchspeaking Catholics. Using data from Gallup polls, the authors compare the evolution of the opinions of French-speaking Quebec Catholics and Englishspeaking Ontario Protestants on matters related to sexual and family behaviour from the 1950s to the beginning of the 2000s. The general result is that the evolution of the differences between the two groups is compatible with the hypothesis.

    The results performed by the Institut de Recherche d'Hydro-Quebec as part of the Canada-wide effort to characterize electric and magnetic field levels in different environments are reported. In addition to developing instrumentation for 24 hour recording of fields, measurements were carried out in domestic, light industrial, and agricultural environments as well as in generating stations, substations and under power transmission and distribution lines. Measurements in eighteen dwellings, ranging from single family houses to apartments, displayed average electric fields of less than 12 V/m, while average magnetic fields ranged between 0.04 and 9 milligauss. Magnetic fields measured in offices, light industrial and agricultural environments also fell in the same range. Highest magnetic fields were measured in generating stations, with levels up to 1,200 mG. Field levels up to 140 mG were measured in high voltage substations, while levels at the fenced boundary were below 6.2 mG. Magnetic fields under power transmission and distribution lines are reasonably symmetric and similar to theoretical profiles. 31 figs., 4 tabs

    Microplastic pollution was studied in China's largest inland lake - Qinghai Lake in this work. Microplastics were detected with abundance varies from 0.05 × 10 5 to 7.58 × 10 5 items km -2 in the lake surface water, 0.03 × 10 5 to 0.31 × 10 5 items km -2 in the inflowing rivers, 50 to 1292 items m -2 in the lakeshore sediment, and 2 to 15 items per individual in the fish samples, respectively. Small microplastics (0.1-0.5 mm) dominated in the lake surface water while large microplastics (1-5 mm) are more abundant in the river samples. Microplastics were predominantly in sheet and fiber shapes in the lake and river water samples but were more diverse in the lakeshore sediment samples. Polymer types of microplastics were mainly polyethylene (PE) and polypropylene (PP) as identified using Raman Spectroscopy. Spatially, microplastic abundance was the highest in the central part of the lake, likely due to the transport of lake current. Based on the higher abundance of microplastics near the tourist access points, plastic wastes from tourism are considered as an important source of microplastics in Qinghai Lake. As an important area for wildlife conservation, better waste management practice should be implemented, and waste disposal and recycling infrastructures should be improved for the protection of Qinghai Lake.

    2014-12-01

    Full Text Available The aim of the study was to locate and describe groundwater outflows in a selected lake basin. The study hypothesis was based on the fact that, according to the specialist literature, one of the forms of lake water supply is through groundwater outflows. It was also assumed that the lakes of the Kashubian Lake District are characterised by such a form of lake water supply. The time scope of the work included the period from January 2011 to September 2012. The spatial scope of the work included the area of Lake Raduńskie Górne, located in the Kashubian Lake District in north Poland. The research plot was in the north-eastern part of the lake. Office works were aimed at gathering and studying source materials and maps. Cartographic materials were analysed with the use of the MapInfo Professional 9.5. The purpose of the field work was to find the groundwater outflows in the basin of Lake Raduńskie Górne. During the field research diving was carried out in the lake. During the dive audiovisual documentation was conducted using a Nikon D90 camera with Ikelite underwater housing for Nikon D90 and an Ikelite DS 161 movie substrobe, as well as a GoPro HD HERO 2 Outdoor camera. During the project, four groundwater outflows were found. In order to examine these springs audiovisual and photographic documentation was made. To systematise the typology of the discovered springs, new nomenclature was suggested, namely under-lake springs with subtypes: an under-lake slope spring and under-lake offshore spring

  7. Changing values of lake ecosystem services as a result of bacteriological contamination on Lake Trzesiecko and Lake Wielimie, Poland

    Full Text Available Lake ecosystems, on the one hand, are affected by tourism, and on the other by development for tourism. Lake ecosystem services include: water with its self-cleaning processes, air with climate control processes, as well as flora and fauna. Utilisation of services leads to interventions in the structure of ecosystems and their processes. Only to a certain extent, this is specific to each type of environmental interference, remains within the limits of ecosystem resilience and does not lead to its degradation. One of the threats is bacteriological contamination, for which the most reliable sanitation indicator is Escherichia coli. In lake water quality studies it is assumed that the lakeshore cannot be a source of bacteria. It has been hypothesised that the problem of bacterial contamination can be serious for the places that do not have any infrastructure, especially sanitation. Consequently, the purpose of the study was to determine the extent to which lakeshore sanitation, in particular the level of bacteriological contamination, has an impact on the value of services provided by the selected lake ecosystems (Lake Trzesiecko and Lake Wielimie – Szczecinek Lake District. Five selected services related to lake ecosystems are: water, control over the spread of contagious diseases, aesthetic values, tourism and recreation, as well as the hydrological cycle with its self-cleaning function. Services, as well as the criteria adopted for evaluation, allow us to conclude that the services provided by the lake ecosystems are suitable to fulfill a recreation function. However, the inclusion of quality criteria for sanitary status has shown that the value of system services has dropped by as much as 50%. Value changes are visible primarily for water and aesthetic qualities. Such a significant decrease in the value of services clearly indicates the importance of the sanitary conditions of lakes and their appropriate infrastructure. In view of the

  8. Resilience and Restoration of Lakes

    Directory of Open Access Journals (Sweden)

    Stephen R. Carpenter

    1997-06-01

    Full Text Available Lake water quality and ecosystem services are normally maintained by several feedbacks. Among these are nutrient retention and humic production by wetlands, nutrient retention and woody habitat production by riparian forests, food web structures that cha nnel phosphorus to consumers rather than phytoplankton, and biogeochemical mechanisms that inhibit phosphorus recycling from sediments. In degraded lakes, these resilience mechanisms are replaced by new ones that connect lakes to larger, regional economi c and social systems. New controls that maintain degraded lakes include runoff from agricultural and urban areas, absence of wetlands and riparian forests, and changes in lake food webs and biogeochemistry that channel phosphorus to blooms of nuisance al gae. Economic analyses show that degraded lakes are significantly less valuable than normal lakes. Because of this difference in value, the economic benefits of restoring lakes could be used to create incentives for lake restoration.

    Adverse psychosocial work factors are recognized as a significant source of psychological distress, resulting in a considerable socioeconomic burden. The impact of occupational health standards that aim to reduce these adverse work factors, such as the Quebec Healthy Enterprise Standard (QHES), is of great interest for public health. The aim of this study was to evaluate, for the first time, the effect of QHES interventions targeting adverse psychosocial work factors on the prevalence of these factors and of psychological distress among ten Quebec organizations. These outcomes were assessed by questionnaire using validated instruments before (T1, n = 2849) and 2-3 years following (T2, n = 2560) QHES implementation. Beneficial effects of interventions were observed for two adverse psychosocial work factors: low rewards (ratio of prevalence ratios (PRs) = 0.77, 95% CI = 0.66-0.91) and low social support at work (ratio of PRs = 0.89, 95% CI = 0.77-1.03). Moreover, beneficial effects of interventions were also observed on the prevalence of high psychological distress (ratio of PRs = 0.86, 95% CI = 0.75-0.998). Psychosocial interventions implemented in the context of this standard improved the psychosocial work environment and had beneficial effects on workers' mental health.

    The ski and golf industries in southern Quebec are 2 major sectors of the province's tourism industry and both are sensitive to climate change. The impacts that are attributable to future climate change can significantly affect the profitability and viability of these recreational activities in southern Quebec. This paper presented the results of detailed studies conducted in regions around Montreal, Quebec City and the Eastern Townships in which the diagnostic outputs of 2 coupled atmosphere-ocean general circulation models (GCM) were used to analyze the impact of climate change on the ski and golf industries. The models were used for 3 time periods: a control period from 1961 to 1990; a short term future period from 2010 to 2039; and a long-term future period from 2040-2069. The climate variables chosen for the impacts and adaptation studies included maximum and minimum air temperature, precipitation, atmospheric humidity and wind speeds. Environment Canada provided the data for the control period, and the gaps for missing data were filled by regression analyses between neighbouring stations. The outputs of the 2 GCMs were used to determine the changes in the selected climate variables for the 2 future time periods. Irrigation requirements for the golfing season were calculated for each of the stations within the study area for the 3 time periods. The study showed that future climate change and variability will have significant impacts on these 2 key sectors in southern Quebec. The important changes in variety of key climate variables and parameters, mainly temperature and precipitation, will cause negative impacts, more so for the ski industry as opposed to the golf sector. There will be a significant reduction in the length of the ski season in the future, and snow-making may be the only possibility for some of the 84 ski centers in southern Quebec to continue to operate. However, less intense cold may favour the number of skiable days for certain centres

  12. Combining the Power of Wind and Water in Quebec

    Wind varies and is impossible to store, major factors that have curbed and continue to curb the development of wind power. Hydroelectric generating stations with reservoirs, on the other hand, are quite capable of adjusting their output and can thus buffer fluctuations in consumption or in the output of other generating facilities on the grid. Combining wind power and hydropower thus involves using hydroelectric generating stations to offset the intermittent nature of wind power. The consumer, however, does not automatically reap the benefits of this complementarity. To achieve this, Quebec has implemented a 1,000-MW balancing agreement between the hydropower producer and the electricity distributor, which has signed wind power purchase agreements. The balancing agreement establishes two charges: one based on firming capacity provided by the producer and another linked to errors in the forecast of wind power generation that the distributor makes each day. This structure compensates the producer for the reduced margin of flexibility it has to engage in energy trading. (auth)

    Smoking cessation strategies are barely discussed in nursing education programs, even though initial education shapes how future professionals practice their profession. The aim of this research is to describe the practices, attitudes, and beliefs of nursing educators of Quebec with regard to smoking cessation strategies in initial nursing education. A descriptive design was chosen along with an online questionnaire. A total of 278 educators (20.8%) participated in the survey. Although educators recognize the importance of incorporating smoking cessation strategies into their teaching practice, they allocate an average of only one hour per year to the topic. Tobacco use is addressed mostly in terms of risk factors, with little focus on how to help patients quit. The perceived obstacles are related to false beliefs and a lack of knowledge. The results of this study demonstrate the need to raise educators' awareness of the importance of incorporating smoking cessation strategies into classroom teaching. © The Author(s) 2013.

    Full Text Available Considerable Nanoarchaeota novelty and diversity were encountered in Yellowstone Lake, Yellowstone National Park, where sampling targeted lake floor hydrothermal vent fluids, streamers and sediments associated with these vents, and in planktonic photic zones in three different regions of the lake. Significant homonucleotide repeats (HR were observed in pyrosequence reads and in near full-length Sanger sequences, averaging 112 HR per 1,349 bp clone and could confound diversity estimates derived from pyrosequencing, resulting in false nucleotide insertions or deletions (indels. However, Sanger sequencing of two different sets of PCR clones (110 bp, 1349 bp demonstrated that at least some of these indels are real. The majority of the Nanoarchaeota PCR amplicons were vent associated; however, curiously, one relatively small Nanoarchaeota OTU (70 pyrosequencing reads was only found in photic zone water samples obtained from a region of the lake furthest removed from the hydrothermal regions of the lake. Extensive pyrosequencing failed to demonstrate the presence of an Ignicoccus lineage in this lake, suggesting the Nanoarchaeota in this environment are associated with novel Archaea hosts. Defined phylogroups based on near full-length PCR clones document the significant Nanoarchaeota 16S rRNA gene diversity in this lake and firmly establish a terrestrial clade distinct from the marine Nanoarcheota as well as from other geographical locations.

  15. Contaminant trends in lake trout and walleye from the Laurentian Great Lakes

    Trends in PCBs, DDT, and other contaminants have been monitored in Great Lakes lake trout and walleye since the 1970s using composite samples of whole fish. Dramatic declines have been observed in concentrations of PCB, ΣDDT, dieldrin, and oxychlordane, with declines initially following first order loss kinetics. Mean PCB concentrations in Lake Michigan lake trout increased from 13 μg/g in 1972 to 23 μg/g in 1974, then declined to 2.6 μg/g by 1986. Between 1986 and 1992 there was little change in concentration, with 3.5 μg/g observed in 1992. ΣDDT in Lake Michigan trout followed a similar trend, decreasing from 19.2 μg/g in 1970 to 1.1 μg/g in 1986, and 1.2 μg/g in 1992. Similar trends were observed for PCBs and ΣDDT in lake trout from Lakes Superior, Huron and Ontario. Concentrations of both PCB and ΣDDT in Lake Erie walleye declined between 1977 and 1982, after which concentrations were relatively constant through 1990. When originally implemented it was assumed that trends in the mean contaminant concentrations in open-lake fish would serve as cost effective surrogates to trends in the water column. While water column data are still extremely limited it appears that for PCBs in lakes Michigan and Superior, trends in lake trout do reasonably mimic those in the water column over the long term. Hypotheses to explain the trends in contaminant concentrations are briefly reviewed. The original first order loss kinetics used to describe the initial decline do not explain the more recent leveling off of contaminant concentrations. Recent theories have examined the possibilities of multiple contaminant pools. We suggest another hypothesis, that changes in the food web may have resulted in increased bioaccumulation. However, a preliminary exploration of this hypothesis using a change point analysis was inconclusive.

    After twenty years serving its members, the Quebec Healthy Cities and Towns Network (QHCTN) faces several challenges. There are currently many changes being made in the local organization and the administration of services. The Network, through its capacity to mobilize the different municipalities, is the best placed to advocate and support a coordinated approach to government initiatives and also to encourage partnerships with other institutions (education, health, socio-economic) and communities. There is, nonetheless, a need to rethink its direct support to members, especially in terms of communication and networking among them.

    Lake Mariut, south Alexandria, Egypt suffered in the recent decades from intensive pollution as a result of a continuous discharge of huge amounts of agriculture wastewater that contains a large concentration of the washed pesticides and fertilizers in addition to domestic and industrial untreated wastewater. The over flow from the lake is discharged directly to the sea through El-Max pumping station via EI-Umum drain. Lake Mariout is surrounded by a huge number of different industrial activities and also the desert road is cutting the lake, this means that a huge number of various pollutants cycle through the air and settle down in the lake, by the time and during different seasons these pollutants after accumulation and different chemical interactions will release again from the lake to the surrounding area affecting the surrounding zone

    The Great Lakes are the largest group of freshwater lakes on Earth that approximately 37 million people depend upon for fresh drinking water, food, flood and drought mitigation, and natural resources that support industry, jobs, shipping and tourism. Recent reports have stated (e.g., the National Climate Assessment) that climate change can impact and exacerbate a range of risks to the Great Lakes, including changes in the range and distribution of certain fish species, increased invasive species and harmful algal blooms, declining beach health, and lengthened commercial navigation season. In this study, we will examine the impact of climate change on the Laurentian Great Lakes through investigation of long-term lake surface water temperatures (LSWT). We will use the ATSR Reprocessing for Climate: Lake Surface Water Temperature & Ice Cover (ARC-Lake) product over the period 1995-2012 to investigate individual and interlake variability. Specifically, we will quantify the seasonal amplitude of LSWTs, the first and last appearances of the 4°C isotherm (i.e., an important identifier of the seasonal evolution of the lakes denoting winter and summer stratification), and interpret these quantities in the context of global interannual climate variability such as ENSO.

    2017-01-01

    Lake Cadagno (26 ha) is a crenogenic meromictic lake located in the Swiss Alps at 1921 m asl with a maximum depth of 21 m. The presence of crystalline rocks and a dolomite vein rich in gypsum in the catchment area makes the lake a typical “sulphuretum ” dominated by coupled carbon and sulphur...... cycles. The chemocline lies at about 12 m depth, stabilized by density differences of salt-rich water supplied by sub-aquatic springs to the monimolimnion and of electrolyte-poor surface water feeding the mixolimnion. Steep sulphide and light gradients in the chemocline support the growth of a large...... in the chemocline. Small-celled PSB together with the sulfate-reducing bacterium Desulfocapsa thiozymogenes sp. form stable aggregates in the lake, which represent small microenvironments with an internal sulphur cycle. Eukaryotic primary producers in the anoxic zones are dominated by Cryptomonas phaseolus...

  20. Recent lake ice-out phenology within and among lake districts of Alaska, U.S.A.

    Arp, Christopher D.; Jones, Benjamin M.; Grosse, Guido

    2013-01-01

    The timing of ice-out in high latitudes is a fundamental threshold for lake ecosystems and an indicator of climate change. In lake-rich regions, the loss of ice cover also plays a key role in landscape and climatic processes. Thus, there is a need to understand lake ice phenology at multiple scales. In this study, we observed ice-out timing on 55 large lakes in 11 lake districts across Alaska from 2007 to 2012 using satellite imagery. Sensor networks in two lake districts validated satellite observations and provided comparison with smaller lakes. Over this 6 yr period, the mean lake ice-out for all lakes was 27 May and ranged from 07 May in Kenai to 06 July in Arctic Coastal Plain lake districts with relatively low inter-annual variability. Approximately 80% of the variation in ice-out timing was explained by the date of 0°C air temperature isotherm and lake area. Shoreline irregularity, watershed area, and river connectivity explained additional variation in some districts. Coherence in ice-out timing within the lakes of each district was consistently strong over this 6 yr period, ranging from r-values of 0.5 to 0.9. Inter-district analysis of coherence also showed synchronous ice-out patterns with the exception of the two arctic coastal districts where ice-out occurs later (June–July) and climatology is sea-ice influenced. These patterns of lake ice phenology provide a spatially extensive baseline describing short-term temporal variability, which will help decipher longer term trends in ice phenology and aid in representing the role of lake ice in land and climate models in northern landscapes.

    Petit, Marie-Claude

    This research focuses on the management of project managers (PMs) working in high technology organizations. In particular, it examines how these professionals are taken charge of from a human resources management (HRM) standpoint in firms within the aerospace industry in Quebec. The literature in the field of project management generally depicts PMs as entrepreneurs and resource managers, managing human resources (e.g. project team members) among other things. It also defines them as single-handedly responsible for managing their own career, stress and motivation. This profile suggests that once selected and assigned to projects, PMs receive little attention in terms of HRM from the organization. It is hardly conceivable, however, that PMs would move about completely on their own within the organization, let alone that they wouldn't represent any special challenge in terms of HRM, as the ones the literature so clearly underlines for project team members. The review of the literature also reveals that the subject of HRM as applied to PMs is poorly documented empirically, especially on the topic of what particular challenges the project context might bring up for the HRM of PMs. There is also little told about the actors involved in supporting and contributing to meet the challenges that arise out of managing PMs. This study sought to discern those challenges and the means put forth to address them. Also, it wanted to identify the actors of the HRM of PMs, their roles, their skills, and their relationships, among themselves and with the PMs, in order to efficiently take charge of them. This study also wanted to demonstrate the logic that ties the means put forth by the identified actors with the objectives PM-employing organizations want to reach. Finally, the study wanted to identify the impact of the HRM of PMs as it is occurring in organizations. The Quebec aerospace sector was chosen as the field of research primarily because the success of projects in

    This paper presented the results of a study in which 3 regional seismic reflection lines originally acquired in 1978 were reprocessed and reinterpreted using current techniques and methodologies. The profiles cross the Chambly-Fortierville syncline and provide images of the St. Lawrence Platform and the Appalachian foreland thrust belt of southern Quebec, including one that spans the entire width of the southern Quebec Appalachians. Post-stack seismic data processing and time migration were used to improve the quality of the original seismic sections, allowing interpretations that provide new information on subsurface geology, such as the recognition of complex structural patterns in platform and foreland units, the presence of a triangle zone at the structural front, and the geometry of thrust slices of platform units and Appalachian thrust beds, as well as images of the internal Humber Zone, including back-thrust faults and mega thrust wedges. The Saint-Flavien natural gas-field and other potential targets in the St. Lawrence Platform and Appalachian Foreland are imaged in the seismic profiles. The study provided new insights into the structure, geological evolution, and petroleum potential of the St. Lawrence Platform and the Appalachian foreland thrust belt of southern Quebec, including a potential, previously unrecognized Ordovician hydrothermal dolomite play. The new subsurface interpretations give a clearer view of the major structure affecting the Utica Shale, providing new insights into the limits of the unconventional shale gas play in the St. Lawrence Platform. 53 refs., 8 figs.

    Since the dawn of civilization waterfront land has been an irresistible attraction to man. Throughout history he has sought out locations fronting on oceans, rivers, and lakes. Originally sought for proximity .to water supply and transportation, such locations are now sought more for their esthetic qualities and for recreation. Usable natural waterfront property is limited, however, and the more desirable sites in many of our urban areas have already been taken. The lack of available waterfront sites has led to the creation of many artificial bodies of water. The rapid suburbanization that has characterized urban growth in America since the end of World War II, together with increasing affluence and le-isure time, has created a ready market for waterfront property. Accordingly, lake-centered subdivisions and developments dot the suburban landscape in many of our major urban areas. Literally thousands of lakes surrounded by homes have materialized during this period of rapid growth. Recently, several "new town" communities have been planned around this lake-centered concept. A lake can be either an asset or a liaoility to a community. A clean, clear, attractively landscaped lake is a definite asset, whereas a weed-choked, foul-smelling mudhole is a distinct liability. The urban environment poses both problems and imaginative opportunities in the development of lakes. Creation of a lake causes changes in all aspects of the environment. Hydrologic systems and ecological patterns are usually most severely altered. The developer should be aware of the potential changes; it is not sufficient merely to build a dam across a stream or to dig a hole in the ground. Development of Gl a successful lake requires careful planning for site selection and design, followed by thorough and cc ntinual management. The purpose of this report is to describe the characteristics of real-estate lakes, to pinpoint potential pmblems, and to suggest possible planning and management guidelines

    It is well known that dissolved organic matter (DOM) increases in lakes associated with forestry activity but characterization of the DOM structure is incomplete. Twenty-three lakes with a wide range of forestry activities located in central Quebec, Canada were sampled and analyzed for dissolved organic carbon (DOC) concentration, DOC fluorescence, and ultra violet-visible (UV-VIS) absorption spectra. The results show that DOC increases (as does the associated DOC fluorescence) with increased logging (slope = 0.122, r 2 = 0.581, p 2 = 0.308, p -2 , r 2 = 0.331, p 13 C solid-state nuclear magnetic resonance ( 13 C NMR) analysis. XANES analysis of functional groups in the four concentrated samples shows that there are significant differences in reduced sulphur between the samples, however there was no clear relationship with forestry activity in the associated catchment. XRD data showed the presence of amorphous sulphide minerals associated with the DOM concentrate that may be important sites for mercury binding. The 13 C NMR spectra of these samples show that the percentage of carbon present in carboxylic functional groups increases with increasing logging. Such structures are important for binding photo-reducible mercury and their presence may limit mercury photo-reduction and volatilization. We propose a mechanism by which increased logging leads to increased carboxylic groups in DOM and thereby increased weak binding of photo-reducible mercury. These results, in part, explain the decrease in dissolved gaseous mercury (DGM) production rates with increased logging found in our previous work

  14. Circulation and sedimentation in a tidal-influenced fjord lake: Lake McKerrow, New Zealand

    Science.gov (United States)

    Pickrill, R. A.; Irwin, J.; Shakespeare, B. S.

    1981-01-01

    Lake McKerrow is a tide-influenced fjord lake, separated from the open sea by a Holocene barrier spit. Fresh, oxygenated waters of the epilimnion overlie saline, deoxygenated waters of the hypolimnion. During winter, water from the Upper Hollyford River interflows along the pycnocline, depositing coarse silt on the steep delta and transporting finer sediment down-lake. An extensive sub-lacustrine channel system on the foreset delta slope is possibly maintained by turbidity currents. Saline waters of the hypolimnion are periodically replenished. During high tides and low lake levels saline water flows into the lake and downslope into the lake basin as a density current in a well defined channel.

    Botos Lake, located at the Poas Volcano complex (Costa Rica) was sampled eight times from 1994 to 1996 for physicochemical conditions of the water column and phytoplanktonic community composition. Depth was measured at fixed intervals in several transects across the lake to determine its main morphometric characteristics. The lake has an outlet to the north. It is located 2580 m above sea level and is shallow, with a mean depth of 1.8 m and a relative depth of 2.42 (surface area 10.33 ha, estimated volume 47.3 hm3). The lake showed an isothermal water column in all occasions, but it heats and cools completely according to weather fluctuations. Water transparency reached the bottom on most occasions (> 9 m). The results support the idea that the lake is polymictic and oligotrophic. The lake has at least 23 species of planktonic algae, but it was always dominated by dinoflagellates, especially Peridinium inconspicuum. The shore line is populated by a sparse population of Isoetes sp. and Eleocharis sp. mainly in the northern shore where the bottom has a gentle slope and the forest does not reach the shore.

    In 1990, the province of Quebec adopted a law authorizing the evaluation of the practice of midwifery through eight pilot projects. The projects, which took the form of birth centres outside hospitals, started operating in 1994. The objectives of the evaluation were 1) to compare midwives' services to current physician services with regard to maternal and neonatal mortality and morbidity, the use of obstetrical intervention, individualization and continuity of care as perceived by clients, and cost; and 2) to identify the professional and organizational factors associated with the integration of midwives into the health care system. A mixed evaluative design was used: a multiple case study with each pilot project representing a case and a cohort study where 1,000 women followed by midwives in the birth centres were matched with 1,000 women followed by physicians in the usual hospital-based services. Various quantitative and qualitative data collection instruments were used. Overall, many results were favourable to midwifery practice, while some were favourable to medical care. Following the evaluation, the Government of Quebec decided to legalize the practice of midwifery.

    Idiopathic pulmonary fibrosis (IPF), although rare, is a severe and costly disease. To estimate the clinical and economic burden of IPF over multiple years before and after diagnosis using comprehensive administrative databases for the province of Quebec, Canada. Several administrative databases from Quebec, providing information on hospital care, community care, and pharmaceuticals, were linked over a 5-year period ending March 31, 2011, which was before approval of antifibrotic drugs in Canada. Prevalent and incident IPF cases were defined using International Classification Disease-10-CA codes and International Classification Disease-9-CM codes. We used a broad definition that excluded cases with subsequent diagnosis of other interstitial lung diseases and a narrow definition that required further diagnostic testing to confirm IPF diagnosis. Incident cases had an IPF code in a particular year without any IPF code in the 2 previous years. Health care resource utilization before and after the index diagnosis date was determined and costs calculated. Costs were expressed in 2016 Canadian dollars. Over 5-years, 10,579 (mean age: 76.4; 58% male) satisfied the broad definition of IPF and 8,683 (mean age: 74.5; 57% male) satisfied the narrow definition (82% of broad). Incidences of IPF overall were 25.8 and 21.7/100,000 population for broad and narrow definitions, respectively. Three-year survival was 40% and 37% in broad and narrow cohorts, respectively. For both cohorts, health care resource utilization and costs increased several years before diagnosis ($2,721 and $7,049/patient 5 years and 2 years prior to diagnosis using a broad definition, respectively) and remained elevated for multiple years post diagnosis ($12,978 and $8,267 at 2 and 3 years postdiagnosis). Health care resource utilization and costs of IPF increase many years prior to diagnosis. Incorporating multiyear annual costs before and after diagnosis results in a higher estimate of the economic burden

    2009-07-01

    Full Text Available Questo articolo propone un’analisi storica e una riflessione critica sui modi con cui il Quebec ha affrontato e costantemente riaffronta il problema della scuola pubblica in una società storicamente multiculturale, multietnica e plurilingue. In particolare, la riflessione riguarda il piano normativo e legislativo e le politiche scolastiche via via elaborate, per rispondere alla sfida di pensare e costruire una scuola pubblica capace di costruire una “infanzia quebecchese”. Una lettura del’curricolo ideale’ - si dirà - ci dice poco sulla ‘realtà’ educativa di un paese. Eppure, in Quebec come altrove, le politiche scolastiche costituiscono i segnali pubblici del modo con cui un paese – rappresentando pubblicamente e ufficialmente la sua scuola - rappresenta se stesso, i propri valori, le proprie concezioni di ‘infanzia’. Dopo un breve quadro storico inteso a tracciare l’origine multiculturale del Quebec (come di tutti gli stati nordamericani, par.1, saranno presi in esame la legge 101 (1977 che sancisce il francese come lingua ufficiale di insegnamento e il dibattito sempre vivo e lacerante che ha accompagnato questa legge e le sue successive modifiche (parr. 2-4. In secondo luogo, saranno presi in esame il recente processo di laicizzazione della scuola quebecchese sancito dalla legge 118 (giugno 2000 e le profonde implicazioni culturali, politiche e identitarie di tale processo (parr. 5-8. In un paese che storicamente ha fatto un uso a carattere esplicitamente identitario del riferimento alle religioni dei due gruppi maggioritari, che ha costruito su esso la propria organizzazione sociale, le identità dei gruppi e i loro rapporti di forza, la deconfessionalizzazione della scuola pubblica ha implicazioni e significati culturali del tutto peculiari. Infine sarà analizzata l’assunzione ufficiale della vocazione interculturale della scuola pubblica (parr. 9-11. L’incrocio di questi tagli prospettici fa emergere i

    Hydro Quebec's Research Centre (IREQ), has developed a variety of inspection tools over the years. The Metar bracelet for the feeder tubes, the REC robot for the heat exchanger and the RIT robot for the Delayed Neutron system just to name a few. This paper discusses with the successful deployment of the Camera Probe Positioning robot for Visual Inspection of the sample lines of the delayed neutron system of CANDU power plants. This RIT robot has three possible configurations (Face, Cabinet and LRG configurations) and has remained a prototype version although it has been used over the years in many outage inspection campaigns since 1997. The main advantages of using this robot are: the significant reduction in radiation exposure, the high quality of the data collected and the archiving of inspection data for further analysis and reports. In 2007, Gentilly-2 (G-2), decided to industrialize the LRG configuration of the RIT robot and to designate it the standard tool for the inspection of the Delayed Neutron System. An improved RIT-LRG robot, along with its control box and command station was developed. The software had to be rewritten requiring an ergonomics analysis of user tasks, work station and interface display. These issues included both physical and cognitive requirements aspects. The two principal topics of this paper will be on the Inspection Robot Technology developed and highlights of the 2008 outage inspection campaign. (author)

    This paper presents a relevant approach to predict the indoor radon potential based on the combination of the radiogeochemical data and the indoor radon measurements in the Quebec province territory (Canada). The Quebec ministry of health asked for such a map to identify the radon-prone areas to manage the risk for the population related to indoor radon exposure. Three radiogeochemical criteria including (1) equivalent uranium (eU) concentration from airborne surface gamma-ray surveys, (2) uranium concentration measurements in sediments, (3) bedrock and surficial geology were combined with 3082 basement radon concentration measurements to identify the radon-prone areas. It was shown that it is possible to determine thresholds for the three criteria that implied statistically significant different levels of radon potential using Kruskal–Wallis one way analyses of variance by ranks. The three discretized radiogeochemical datasets were combined into a total predicted radon potential that sampled 98% of the studied area. The combination process was also based on Kruskal–Wallis one way ANOVA. Four statistically significant different predicted radon potential levels were created: low, medium, high and very high. Respectively 10 and 13% of the dwellings exceed the Canadian radon guideline of 200 Bq/m{sup 3} in low and medium predicted radon potentials. These proportions rise up to 22 and 45% respectively for high and very high predicted radon potentials. This predictive map of indoor radon potential based on the radiogeochemical data was validated using a map of confirmed radon exposure in homes based on the basement radon measurements. It was shown that the map of predicted radon potential based on the radiogeochemical data was reliable to identify radon-prone areas even in zones where no indoor radon measurement exists. - Highlights: • 5 radiogeochemical datasets were used to map the geogenic indoor radon potential. • An indoor radon potential was determined for

    Beaver Lake and Radok Lake, the largest known epishelf lake and the deepest freshwater lake on the Antarctic continent, respectively, were isotopically (δ 2 H, δ 18 O) and hydrogeochemically studied. Radok Lake is an isothermal and nonstratified, i.e. homogeneous water body, while Beaver Lake is stratified with respect to temperature, salinity and isotopic composition. The results for the latter attest to freshwater (derived from snow and glacier melt) overlying seawater. (author)

    A new method for the determination of radon in air has been developed. it is based on low temperature absorption of radon in ortho-xylene followed by liquid scintillation counting. The method is reasonably fast and sensitive enough to analyse air without precipitation. The detection limit at the 95% confidence level for a 20 l air sample and 1 h counting time is 2 mBql{sup -1}. Radon concentrations measured in indoor air in Quebec varied from 7 to 162 mBql{sup -1}. (Author).

    1986-01-01

    The relationship between ambulatory physician use and hospitalization was studied using aggregate data in the Province of Quebec, Canada. The analysis showed that the introduction of health insurance covering physician services had a negligible influence on hospitalization. The average length of short-term hospital stays was determined by the proportion of aged population, the proportion of English speaking persons, and the prior level of hospitalization in the medical market areas. Overall, hospital discharge rates remained very constant during the period of six years (1970-1975). There were, however, reductions in hospitalization for infectious diseases, diseases of the blood and blood-forming organs, respiratory diseases, and diseases of the skin and subcutaneous tissue, and increases in the hospitalization rates for neoplasms, circulatory system disorders, musculoskeletal conditions, congenital anomalies, and perinatal morbidity and mortality.

    The advent of new technologies and social media offers a host of possibilities for teenagers to consolidate social networks. Unfortunately, new technologies also represent a potential setting for experiences of victimization. The present study explores the prevalence of cyberbullying victimization in a representative sample of 8 194 teenagers in Quebec and the adverse associated consequences. Results indicate that 18% of boys and close to 1 out of 4 girls report at least one incident of cyberbullying in the past 12 months. Cyberbullying victimization contributes to the prediction of low selfesteem and psychological distress over and above other experiences of bullying in schools or other settings. Cyberbullying appear as one important target for the design of prevention and intervention services designed for youth. Copyright © 2014 Elsevier B.V. All rights reserved.

    Reasons for Hydro-Quebec to have an environmental management system are described. It is said to form the basis of the new 'hands-off' governance, empowerment and accountability regime, it supports expansion of the electricity market, demonstrates effectiveness of environmental management, implements a systematic approach to environmental management, and most of all, because it makes good business sense. The principles of implementation such as embedding responsibility for environmental management system implementation and maintenance into the mission of individual unit, thus recognizing the different needs and rates of implementation by the 1800+ sites and activities of the Corporation, success factors, and the current state of implementation are also reviewed

  14. Lake Generated Microseisms at Yellowstone Lake as a Record of Ice Phenology

    Science.gov (United States)

    2017-12-01

    It has recently been shown that wave action in lakes produces microseisms, which generate noise peaks in the period range of 0.8-1.2 s as recorded by nearby seismic stations. Such noise peaks have been observed at seven seismic stations (H17A, LKWY, B208, B944, YTP, YLA, and YLT) located within 2 km of the Yellowstone Lake shoreline. Initial work using 2016 data shows that the variations in the microseism signals at Yellowstone Lake correspond with the freezing and thawing of lake ice: the seismic noise occurs more frequently in the spring, summer, and fall, and less commonly in the winter. If this can be confirmed, then lake-generated microseisms could provide a consistent measure of the freezing and melting dates of high-latitude lakes in remote areas. The seismic data would then be useful in assessing the effects of climate change on the ice phenology of those lakes. In this work, we analyze continuous seismic data recorded by the seven seismic stations around Yellowstone Lake for the years of 1995 to 2016. We generate probability distribution functions of power spectral density for each station to observe the broad elevation of energy near a period of 1 s. The time dependence of this 1-s seismic noise energy is analyzed by extracting the power spectral density at 1 s from every processed hour. The seismic observations are compared to direct measurements of the dates of ice-out and freeze-up as reported by rangers at Yellowstone National Park. We examine how accurate the seismic data are in recording the freezing and melting of Yellowstone Lake, and how the accuracy changes as a function of the number of stations used. We also examine how sensitive the results are to the particular range of periods that are analyzed.

    In 2012 we started a monitoring program at Lake Czechowskie, Poland, because the lake comprises a long Holocene time series of calcite varves until recent times. The aim of the program is to understand how environmental and climatic conditions influence the hydrological conditions and, ultimately, the sediment deposition processes of the lake. Lake Czechowskie is located in the north of Poland in the Pomeranian Lake District and is part of the national park Tuchola Forest. The landscape and the lake is formed by the glacier retreat after the last glaciation (Weichselian). Lake Czechowskie is a typical hardwater lake and has a length of 1.4 km, an average width of 600 m and a lake surface area of ca 4 km. The maximum depth of 32 m is reached in a rather small hollow in the eastern part of the lake. Two different types of sediment traps provide sediment samples with monthly resolution from different water depths (12m, 26m). In addition, hydrological data including water temperature in different depths, water inflow, throughflow and outflow and the depth of visibility are measured. These data allow to describe strength and duration of lake mixing in spring and autumn and its influence on sedimentation. The sediment samples were analyzed with respect to their dry weight (used to calculate mean daily sediment flux), their inorganic and organic carbon contents, the stable C- and O-isotopes of organic matter and calcite as well as N-isotopes of organic matter. For selected samples dominant diatom taxa are determined. Our first results demonstrate the strong influence of the long winter with ice cover until April in 2013 on the sedimentation. A rapid warming in only 9 days starting on April 9th from -0,3 C° to 15,2 C° resulted in fast ice break-up and a short but intensive lake mixing. In consequence of this short mixing period a strong algal bloom especially of Fragilaria and Crysophycea commenced in April and had its maximum in May. This bloom further induced biogenic

    Originally designed in Quebec, the MOI project was a collaboration between two professors of social work from Quebec and two members of the Peruvian NGO called SUR in Villa de Salvador, one of poorest slum areas on the outskirts of Lima. The approach is founded on the notion that the body is the primary instrument through which a person can interact with the world around him or her, and that the physical and mental health of an individual exists within the context of healthy conditions of life that must include at least a basic social and health infrastructure as well as healthy hygiene practices on the part of individuals, families and the local community. Preschool children (ages 4-6), study a different part of the body and its proper care each week through classroom observation games. Parents' help is requested to modify unhealthy conditions, at the same time to enrich the children's experience and to mobilize the community to improve health conditions. During the 1991 cholera epidemic, not a single case was counted in the experimental district, despite its clearly socio-economically impoverished status, and despite the fact that the Ministry of Health recorded 86,650 cases in the Lima-Callao district, accounting for about 40% of the total number of cases in the Peru. The prior work made it easier to explain how cholera is spread and what special new measures needed to be taken in addition to the hygiene habits already taught.(ABSTRACT TRUNCATED AT 250 WORDS)

    This power point presentation described the position of Maclaren Energy Inc in the Great Lakes Power Inc. (GLPI)/Brascan Group. Great Lakes Power operates 20 power plants with over 900 megawatts of installed capacity in Ontario, Quebec, British Columbia and the United States. This presentation outlined market issues, physical entities, congestion management and predictions. Maclaren's investment strategy is to invest in hydro and gas fired generation to provide high end services to preferred customers. The generation and customer portfolios are to be managed separately as they have separate objectives. The company's trading and marketing strategies are highly integrated. Some recent benchmarks for the company include the selling of nearly 425 MW of power to New Brunswick, and the first to supply energy to New England across phase 2, after Hydro-Quebec. In addition, the company has set up a transmission line to Michigan and has recently developed transmission and generation facilities in British Columbia. tabs., figs

  18. Is Lake Chabot Eutrophic?

    Introduction/Abstract: Lake Chabot is an integral part of the East Bay watershed that provides habitats for animals and recreation for humans year-round. Lake Chabot has been in danger of eutrophication due to excessive dumping of phosphorous and nitrogen into the water from the fertilizers of nearby golf courses and neighboring houses. If the lake turned out to be eutrophified, it could seriously impact what is currently the standby emergency water supply for many Castro Valley residents. Eutrophication is the excessive richness of nutrients such as nitrogen and phosphorus in a lake, usually as a result of runoff. This buildup of nutrients causes algal blooms. The algae uses up most of the oxygen in the water, and when it dies, it causes the lake to hypoxify. The fish in the lake can't breathe, and consequently suffocate. Other oxygen-dependant aquatic creatures die off as well. Needless to say, the eutrophication of a lake is bad news for the wildlife that lives in or around it. The level of eutrophication in our area in Northern California tends to increase during the late spring/early summer months, so our crew went out and took samples of Lake Chabot on June 2. We focused on the area of the lake where the water enters, known on the map as Honker Bay. We also took readings a ways down in deeper water for comparison's sake. Visually, the lake looked in bad shape. The water was a murky green that glimmered with particulate matter that swirled around the boat as we went by. In the Honker Bay region where we focused our testing, there were reeds bathed in algae that coated the surface of the lake in thick, swirling patterns. Surprisingly enough, however, our test results didn't reveal any extreme levels of phosphorous or nitrogen. They were slightly higher than usual, but not by any significant amount. The levels we found were high enough to stimulate plant and algae growth and promote eutrophication, but not enough to do any severe damage. After a briefing with a

    Disparity exists between the public view of the "ideal" dentist and patient experiences of dental practice: dentists are expected to be altruistic and patient-centred, yet patient surveys suggest that the profession is overly motivated by profit. To determine how the public views dental care in Quebec. A random sample of comments about Quebec dentists made in 2011 was extracted from the public website RateMDs.com. Dentist characteristics and patient comments were analyzed using descriptive statistics and qualitative deductive and inductive thematic analysis. Eighty-six entries from a random sample of 47 of a possible 750 dentists were extracted and analyzed. Most dentists were men (66%) and worked in Montreal (51%). Patient comments were mainly positive (83%). Themes included overall impressions, communication and care, clinical competence, professionalism and office environment. Positive comments focused on patient-centred communication, in which the patient felt respected and involved in treatment planning; competence, seen as comprehensive, efficient and long-lasting treatment; and professionalism, which included ethical behaviour such as knowing professional limits. Negative comments focused on reticent communication styles that did not encourage patient input; incompetence, which included poor pain management and unnecessary treatment; and unprofessional conduct, such as lack of transparency in pricing. In contrast with the negative image of dentists reported from patient surveys, comments on one public website were primarily positive. Our findings reinforce the importance of patient-centred education and communication training for students and continuing education.

  1. Investigation of Residence and Travel Times in a Large Floodplain Lake with Complex Lake-River Interactions: Poyang Lake (China

    Full Text Available Most biochemical processes and associated water quality in lakes depends on their flushing abilities. The main objective of this study was to investigate the transport time scale in a large floodplain lake, Poyang Lake (China. A 2D hydrodynamic model (MIKE 21 was combined with dye tracer simulations to determine residence and travel times of the lake for various water level variation periods. The results indicate that Poyang Lake exhibits strong but spatially heterogeneous residence times that vary with its highly seasonal water level dynamics. Generally, the average residence times are less than 10 days along the lake’s main flow channels due to the prevailing northward flow pattern; whereas approximately 30 days were estimated during high water level conditions in the summer. The local topographically controlled flow patterns substantially increase the residence time in some bays with high spatial values of six months to one year during all water level variation periods. Depending on changes in the water level regime, the travel times from the pollution sources to the lake outlet during the high and falling water level periods (up to 32 days are four times greater than those under the rising and low water level periods (approximately seven days.

    We determined polychlorinated biphenyl (PCB) concentrations in 61 female lake trout (Salvelinus namaycush) and 71 male lake trout from Lake Ontario (Ontario, Canada and New York, United States). To estimate the expected change in PCB concentration due to spawning, PCB concentrations in gonads and in somatic tissue of lake trout were also determined. In addition, bioenergetics modeling was applied to investigate whether gross growth efficiency (GGE) differed between the sexes. Results showed that, on average, males were 22% higher in PCB concentration than females in Lake Ontario. Results from the PCB determinations of the gonads and somatic tissues revealed that shedding of the gametes led to 3% and 14% increases in PCB concentration for males and females, respectively. Therefore, shedding of the gametes could not explain the higher PCB concentration in male lake trout. According to the bioenergetics modeling results, GGE of males was about 2% higher than adult female GGE, on average. Thus, bioenergetics modeling could not explain the higher PCB concentrations exhibited by the males. Nevertheless, a sexual difference in GGE remained a plausible explanation for the sexual difference in PCB concentrations of the lake trout.

    To characterize the present benthic macroinvertebrate community of L-Lake, Regions 5 and 7 of the reservoir were sampled in September 1995 at the same locations sampled in 1988 and 1989 during the L-Lake monitoring program. The macroinvertebrate community of 1995 is compared to that of 1988 and 1989. The species composition of L-Lake's macroinvertebrate community has changed considerably since 1988-1989, due primarily to maturation of the reservoir ecosystem. L-Lake contains a reasonably diverse macroinvertebrate community that is capable of supporting higher trophic levels, including a diverse assemblage of fish species. The L-Lake macroinvertebrate community is similar to those of many other southeastern reservoirs, and there is no indication that the macroinvertebrate community is perturbed by chemical or physical stressors

    2017-05-25

    IntroductionThe U.S. Geological Survey (USGS), in cooperation with local and other agencies, collects data at selected lakes throughout Wisconsin. These data, accumulated over many years, provide a data base for developing an improved understanding of the water quality of lakes. To make these data available to interested parties outside the USGS, the data are published annually in this report series. The locations of water-quality and lake-stage stations in Wisconsin for water year 2012 are shown in figure 1. A water year is the 12-month period from October 1 through September 30. It is designated by the calendar year in which it ends. Thus, the period October 1, 2011 through September 30, 2012, is called “water year 2012.”The purpose of this report is to provide information about the chemical and physical characteristics of Wisconsin lakes. Data that have been collected at specific lakes, and information to aid in the interpretation of those data, are included in this report. Data collected include measurements of in-lake water quality and lake stage. Time series of Secchi depths, surface total phosphorus and chlorophyll a concentrations collected during non-frozen periods are included for all lakes. Graphs of vertical profiles of temperature, dissolved oxygen, pH, and specific conductance are included for sites where these parameters were measured. Descriptive information for each lake includes: location of the lake, area of the lake’s watershed, period for which data are available, revisions to previously published records, and pertinent remarks. Additional data, such as streamflow and water quality in tributary and outlet streams of some of the lakes, are published online at http://nwis.waterdata.usgs.gov/wi/nwis.Water-resources data, including stage and discharge data at most streamflow-gaging stations, are available online.

  6. Hydrochemical determination of source water contributions to Lake Lungo and Lake Ripasottile (central Italy

    Full Text Available Lake Lungo and Lake Ripasottile are two shallow (4-5 m lakes located in the Rieti Basin, central Italy, that have been described previously as surface outcroppings of the groundwater table. In this work, the two lakes as well as springs and rivers that represent their potential source waters are characterized physio-chemically and isotopically, using a combination of environmental tracers. Temperature and pH were measured and water samples were analyzed for alkalinity, major ion concentration, and stable isotope (δ2H, δ18O, δ13C of dissolved inorganic carbon, and δ34S and δ18O of sulfate composition.  Chemical data were also investigated in terms of local meteorological data (air temperature, precipitation to determine the sensitivity of lake parameters to changes in the surrounding environment. Groundwater represented by samples taken from Santa Susanna Spring was shown to be distinct with SO42- and Mg2+ content of 270 and 29 mg/L, respectively, and heavy sulfate isotopic composition (δ34S=15.2 ‰ and δ18O=10‰. Outflow from the Santa Susanna Spring enters Lake Ripasottile via a canal and both spring and lake water exhibits the same chemical distinctions and comparatively low seasonal variability. Major ion concentrations in Lake Lungo are similar to the Vicenna Riara Spring and are interpreted to represent the groundwater locally recharged within the plain. The δ13CDIC exhibit the same groupings as the other chemical parameters, providing supporting evidence of the source relationships. Lake Lungo exhibited exceptional ranges of δ13CDIC (±5 ‰ and δ2H, δ18O (±5 ‰ and ±7 ‰, respectively, attributed to sensitivity to seasonal changes. The hydrochemistry results, particularly major ion data, highlight how the two lakes, though geographically and morphologically similar, represent distinct hydrochemical facies. These data also show a different response in each lake to temperature and precipitation patterns in the basin that

    Non-native lake trout Salvelinus namaycush displaced native bull trout Salvelinus confluentus in Flathead Lake, Montana, USA, after 1984, when Mysis diluviana became abundant following its introduction in upstream lakes in 1968–1976. We developed a simulation model to determine the fishing mortality rate on lake trout that would enable bull trout recovery. Model simulations indicated that suppression of adult lake trout by 75% from current abundance would reduce predation on bull trout by 90%. Current removals of lake trout through incentivized fishing contests has not been sufficient to suppress lake trout abundance estimated by mark-recapture or indexed by stratified-random gill netting. In contrast, size structure, body condition, mortality, and maturity are changing consistent with a density-dependent reduction in lake trout abundance. Population modeling indicated total fishing effort would need to increase 3-fold to reduce adult lake trout population density by 75%. We conclude that increased fishing effort would suppress lake trout population density and predation on juvenile bull trout, and thereby enable higher abundance of adult bull trout in Flathead Lake and its tributaries.

  8. Simulating groundwater-peatland interactions in depression and slope peatlands in southern Quebec (Canada)

    It is crucial to understand hydrogeological interactions between aquifers and peatlands in order to grasp the influence of aquifers in peatland water budgets, to understand the role of groundwater in the evolution or organic matter deposition, and to quantify how a peatland can sustain groundwater levels in a superficial aquifer. These questions have rarely been addressed in literature and there is currently no understanding of which process dominates aquifer-peatland exchanges in different geomorphological settings. The main purpose of the study was to use groundwater flow modeling to answer these questions in two contrasted geological contexts of southern Quebec (Canada). During a three-year study, six peatlands have been instrumented in the Becancour (Centre-du-Quebec) and Amos (Abitibi-Temiscamingue) regions of southern Quebec (Canada). At each site, either one or two transects of six piezometer nests (at 1.20 m depth in the organic deposits and in the mineral deposits below the peat) have been installed, for a total of twelve aquifer-peatland transects of approximately 500 m. The stratigraphy and geometry of the peatland-aquifer system, as well as the hydrodynamic properties of the organic and mineral deposits have been measured at all sites. Groundwater levels have been recorded from autumn 2010 to summer 2012. The Becancour peatlands have developed in depressions while the Amos peatlands have developed through the paludification of esker slopes. The maximum peat thickness measured in the Bécancour peatlands is 6.4 m while it is 4.5 m in the Amos region. In both regions, peatlands are fringed by sandy deposits that extend at least partly under the organic deposits. The thickness of these underlying deposits is not well defined, but available data suggests a metric scale thickness in areas close to the adjacent superficial aquifer. Field data is used to create 2D numerical models in Modflow to simulate flow between the shallow groundwater and the peatland on

    The palaeolimnological reconstruction of secular evolution of Euroepan Lakes with key socio-economical relevance respect to large (climate change) and local scale (land use, tourism) environmental changes, represents one of the objectives of the project EuLakes (European Lakes Under Environmental Stressors, Supporting lake governance to mitigate the impact of climate change, Reg. N. 2CE243P3), launched in 2010 within the Central European Inititiative. The project consortium comprises lakes of different morphology and prevalent human uses, including the meso-eutrophic Lake Neusiedl, the largest Austrian lake (total area 315 km2), and the westernmost shallow (mean depth 1.2 m) steppe lake of the Euro-Asiatic continent. The volume of Lake Neusiedl can potentially change over the years, in relation with changing balance between atmospheric precipitation and lake water evapotranspiration. Changing water budget, together with high lake salinity and turbidity, have important implications over the lake ecosystem. This contribution illustrates results of the multi-proxi palaeolimnological reconstruction of ecologial changes occurred in Lake Neusiedl during the last ca. 140 years, i.e. since the end of the last "vanished-lake" stage (1865-1871). Geochemical and biological proxies anticipate the increase in lake productivity of ca. 10 years (1950s) respect to what reported in the literature. Diatom species composition indicate a biological lake recovery in the late 1980s, and suggest a second increment in lake productivity since the late 1990s, possibly in relation with the progressive increase in the nitrogen input from agriculture. Abundance of diatoms typical of brackish waters indicated no significant long-term change in lake salinity, while variations in species toleranting dessiccation confirm the vulnerability of Lake Neusiedl toward climate-driven changes in the lake water balance. This fragility is aggravated by the the semi-arid climate conditions of the catchemnt

    Water level and chemistry of Lake Qinghai are sensitive to climate changes and are important for paleoclimatic implications. An accurate understanding of hydrological and chemical budgets is crucial for quantifying geochemical proxies and carbon cycle. Published results of water budget are firstly reviewed in this paper. Chemical budget and residence time of major dissolved constituents in the lake are estimated using reliable water budget and newly obtained data for seasonal water chemistry. The results indicate that carbonate weathering is the most important riverine process, resulting in dominance of Ca 2+ and DIC for river waters and groundwater. Groundwater contribution to major dissolved constituents is relatively small (4.2 ± 0.5%). Wet atmospheric deposition contributes annually 7.4–44.0% soluble flux to the lake, resulting from eolian dust throughout the seasons. Estimates of chemical budget further suggest that (1) the Buha-type water dominates the chemical components of the lake water, (2) Na+, Cl-, Mg 2+ , and K+ in lake water are enriched owing to their conservative behaviors, and (3) precipitation of authigenic carbonates (low-Mg calcite, aragonite, and dolomite) transits quickly dissolved Ca 2+ into the bottom sediments of the lake, resulting in very low Ca 2+ in the lake water. Therefore, authigenic carbonates in the sediments hold potential information on the relative contribution of different solute inputs to the lake and the lake chemistry in the past.

  1. Effects of acidity on primary productivity in lakes: phytoplankton. [Lakes Panther, Sagamore, and Woods

    Energy Technology Data Exchange (ETDEWEB)

    Hendrey, G R

    1979-01-01

    Relationships between phytoplankton communities and lake acidity are being studied at Woods Lake (pH ca. 4.9), Sagamore Lake (pH ca. 5.5), and Panther Lake (pH ca. 7.0). Numbers of phytoplankton species observed as of July 31, 1979 are Woods 27, Sagamore 38, and Panther 64, conforming to other observations that species numbers decrease with increasing acidity. Patterns of increasing biomass and productivity found in Woods Lake may be atypical of similar oligotrophic lakes in that they develop rather slowly instead of occuring very close to ice-out. Contributions of netplankton (net > 48 ..mu..m), nannoplankton (48 > nanno > 20 ..mu..m) and ultraplankton (20 > ultra >0.45 ..mu..m) to productivity per m/sup -2/ show that the smaller plankton are relatively more important in the more acid lakes. This pattern could be determined by nutrient availability (lake acidification leading to decreased availability of phosphorus). The amount of /sup 14/C-labelled dissolved photosynthate (/sup 14/C-DOM), as a percent of total productivity, is ordered Woods > Sagamore > Panther. This is consistent with a hypothesis that microbial heterotrophic activity is reduced with increasing acidity, but the smaller phytoplankton may be more leaky at low pH. (ERB)

  2. Advocacy coalitions and wind power development: Insights from Quebec

    Jegen, Maya; Audet, Gabriel

    2011-01-01

    This article addresses the issue of wind energy acceptance in the Canadian province of Quebec and, in particular, the impact of different models of wind power development on the degree of social acceptance. We show that the dominant advocacy coalition, which favors a hard path energy development in general, enforces a large-scale development of wind energy. Two other coalitions - a soft path coalition and a nationalist coalition - oppose this development, but not wind energy per se. We argue that difference in belief systems explains their opposition rather than planning issues or NIMBY concerns. We also contend that, despite its predominance over (wind) energy policy, the hard path coalition is willing to learn and make concessions towards the soft path coalition, but not towards the nationalist coalition. - Highlights: → We address social acceptance of wind energy. → We illustrate the interaction of advocacy coalitions. → Different advocacy coalitions support different models of wind energy development. → Models of wind energy development influence the degree of social acceptance. → Opposition is not aimed at wind energy per se, but at the hard path model.

  3. Ecology of playa lakes

    Science.gov (United States)

    Haukos, David A.; Smith, Loren M.

    1992-01-01

    Between 25,000 and 30,000 playa lakes are in the playa lakes region of the southern high plains (Fig. 1). Most playas are in west Texas (about 20,000), and fewer, in New Mexico, Oklahoma, Kansas, and Colorado. The playa lakes region is one of the most intensively cultivated areas of North America. Dominant crops range from cotton in southern areas to cereal grains in the north. Therefore, most of the native short-grass prairie is gone, replaced by crops and, recently, grasses of the Conservation Reserve Program. Playas are the predominant wetlands and major wildlife habitat of the region.More than 115 bird species, including 20 species of waterfowl, and 10 mammal species have been documented in playas. Waterfowl nest in the area, producing up to 250,000 ducklings in wetter years. Dominant breeding and nesting species are mallards and blue-winged teals. During the very protracted breeding season, birds hatch from April through August. Several million shorebirds and waterfowl migrate through the area each spring and fall. More than 400,000 sandhill cranes migrate through and winter in the region, concentrating primarily on the larger saline lakes in the southern portion of the playa lakes region.The primary importance of the playa lakes region to waterfowl is as a wintering area. Wintering waterfowl populations in the playa lakes region range from 1 to 3 million birds, depending on fall precipitation patterns that determine the number of flooded playas. The most common wintering ducks are mallards, northern pintails, green-winged teals, and American wigeons. About 500,000 Canada geese and 100,000 lesser snow geese winter in the playa lakes region, and numbers of geese have increased annually since the early 1980’s. This chapter describes the physiography and ecology of playa lakes and their attributes that benefit waterfowl.

  4. Excess unsupported sup(210)Pb in lake sediment from Rocky Mountain lakes

    1985-01-01

    Sediment cores from four high-altitude (approximately 3200 m) lakes in Rocky Mountain National Park, Colorado, were dated by sup(210)Pb chronology. Background (supported) sup(210)Pb activities for the four cores range from 0.26 to 0.93 Beq/g dry weight, high for typical oligotrophic lakes. Integrated unsupported sup(210)Pb ranges from 0.81 (a typical value for most lakes) to 11.0 Beq/cmsup(2). The sup(210)Pb activity in the surface sediments ranges from 1.48 to 22.2 Beq/g dry weight. Sedimentation from Lake Louise, the most unusual of the four, has 22.2 Beq/g dry weight at the sediment surface, an integrated unsupported sup(210)Pb=11.0 Beq/cmsup(2), and supported sup(210)Pb=0.74 Beq/g dry weight. sup(226)Ra content of the sediment is insufficient to explain either the high unsupported sup(210)Pb or the sup(222)Rn content of the water column of Lake Louise, which averaged 96.2 Beq/L. We concluded that sup(222)Rn-rich groundwater entering the lake is the source of the high sup(222)Rn in the water column. This, in turn, is capable of supporting the unusually high sup(210)Pb flux to the sediment surface. Groundwater with high sup(222)Rn may control the sup(210)Pb budget of lakes where sediment cores have integrated unsupported sup(210)Pb greater than 2 Beq/cmsup(2)

    There are presently no data available concerning Internet addiction (IA) problems among adolescents in Canada and the province of Quebec. The goal of this study is thus to document and compare the influence of gender on Internet use and addiction. The study data were collected from a larger research project on gambling among adolescents. Activities conducted online (applications used and time spent) as well as answers to the Internet Addiction Test (IAT) were collected from 3938 adolescents from grades 9 to 11. The two most often employed cut-off points for the IAT in the literature were documented: (40-69 and 70+) and (50+). Boys spent significantly more time on the Internet than did girls. A greater proportion of the girls made intense use of social networks, whereas a greater proportion of the boys made intense use of massively multiplayer online role-playing games, online games, and adult sites. The proportion of adolescents with a potential IA problem varied according to the cut-off employed. When the cut-off was set at 70+, 1.3% of the adolescents were considered to have an IA, while 41.7% were seen to be at risk. At a 50+ cut-off, 18% of the adolescents were considered to have a problem. There was no significant difference between the genders concerning the proportion of adolescents considered to be at risk or presenting IA problems. Finally, analysis of the percentile ranks would seem to show that a cut-off of 50+ better describes the category of young people at risk. The results of this study make it possible to document Internet use and IA in a large number of Quebec adolescents. © The Author(s) 2016.

    Many of the world's saline lakes are shrinking at alarming rates, reducing waterbird habitat and economic benefits while threatening human health. Saline lakes are long-term basin-wide integrators of climatic conditions that shrink and grow with natural climatic variation. In contrast, water withdrawals for human use exert a sustained reduction in lake inflows and levels. Quantifying the relative contributions of natural variability and human impacts to lake inflows is needed to preserve these lakes. With a credible water balance, causes of lake decline from water diversions or climate variability can be identified and the inflow needed to maintain lake health can be defined. Without a water balance, natural variability can be an excuse for inaction. Here we describe the decline of several of the world's large saline lakes and use a water balance for Great Salt Lake (USA) to demonstrate that consumptive water use rather than long-term climate change has greatly reduced its size. The inflow needed to maintain bird habitat, support lake-related industries and prevent dust storms that threaten human health and agriculture can be identified and provides the information to evaluate the difficult tradeoffs between direct benefits of consumptive water use and ecosystem services provided by saline lakes.

    In an energy context dominated by the evolution of needs, the availability of resources and the respect of the environment, electricity will play a role increasingly important in order to make accessible most of the energy resources that are harnessed in real time and not already existing as a portable and storable form. However, to become a complete and efficient accessibility carrier, it will still have to rise to many more challenges in development, exploitation, maintenance and commercial exchanges. The Hydro Quebec research institute (IREQ) has begun several strategic R&D projects to raise to these challenges. [French] Dans un contexte energetique domine par l'evolution des besoins, la disponibilite des ressources et le respect de l'environnement, l'electricite jouera un role de plus en plus important pour rendre accessibles la plupart des ressources energetiques qui sont captees en temps reel et qui ne sont pas deja sous une forme stockable et transportable. Cependant, pour devenir un vecteur d'accessibilite complet et efficace, elle devra encore relever plusieurs defis au niveau du developpement, de l'exploitation, de la maintenance et des echanges commerciaux. L'institut de recherche d'Hydro-Quebec (IREQ) a entrepris plusieurs projets de R&D strategique visant a relever ces defis.

    Remote high-elevation lakes represent unique environments for evaluating the bioaccumulation of atmospherically deposited mercury through freshwater food webs, as well as for evaluating the relative importance of mercury loading versus landscape influences on mercury bioaccumulation. The increase in mercury deposition to these systems over the past century, coupled with their limited exposure to direct anthropogenic disturbance make them useful indicators for estimating how changes in mercury emissions may propagate to changes in Hg bioaccumulation and ecological risk. We evaluated mercury concentrations in resident fish from 28 high-elevation, sub-alpine lakes in the Pacific Northwest region of the United States. Fish total mercury (THg) concentrations ranged from 4 to 438 ng/g wet weight, with a geometric mean concentration (±standard error) of 43 ± 2 ng/g ww. Fish THg concentrations were negatively correlated with relative condition factor, indicating that faster growing fish that are in better condition have lower THg concentrations. Across the 28 study lakes, mean THg concentrations of resident salmonid fishes varied as much as 18-fold among lakes. We used a hierarchal statistical approach to evaluate the relative importance of physiological, limnological, and catchment drivers of fish Hg concentrations. Our top statistical model explained 87% of the variability in fish THg concentrations among lakes with four key landscape and limnological variables: catchment conifer density (basal area of conifers within a lake's catchment), lake surface area, aqueous dissolved sulfate, and dissolved organic carbon. Conifer density within a lake's catchment was the most important variable explaining fish THg concentrations across lakes, with THg concentrations differing by more than 400 percent across the forest density spectrum. These results illustrate the importance of landscape characteristics in controlling mercury bioaccumulation in fish.

    Beaver Lake and Lake Radok, the largest known epishelf and the deepest freshwater lake on the Antarctic continent, respectively, were isotopically (δ 2 H, δ 18 O) and hydrogeochemically studied. Lake Radok is an isothermal and non-stratified, i.e. homogeneous water body, while Beaver Lake is stratified with respect to temperature, salinity and isotopic composition. The results for the latter attest to freshwater (derived from snow and glacier melt) overlying seawater. (author)

    The report is a synoptic review of data collected over the past twenty years on the chemistry of Lake Michigan. Changes in water quality and sediment chemistry, attributable to cultural and natural influences, are considered in relation to interacting processes and factors controlling the distribution and concentration of chemical substances within the Lake. Temperature, light, and mixing processes are among the important natural influences that affect nutrient cycling, dispersal of pollutants, and fate of materials entering the Lake. Characterization of inshore-offshore and longitudinal differences in chemical concentrations and sediment chemistry for the main body of the Lake is supplemented by discussion of specific areas such as Green Bay and Grand Traverse Bay. Residues, specific conductance, dissolved oxygen, major and trace nutrients, and contaminants are described in the following context: biological essentiality and/or toxicity, sources to the Lake, concentrations in the water column and sediments, chemical forms, seasonal variations and variation with depth. A summary of existing water quality standards, statutes, and criteria applicable to Lake Michigan is appended.

    Lake Erie, the fourth largest in surface area, smallest in volume and shallowest among the Great Lakes is approximately 400 km long and 90 km wide. Short term lake level variations are due to storm surge generated by high winds and moving pressure systems over the lake mainly in the southwest-northeast direction, along the lakes longitudinal axis. The historical wave data from three active offshore buoys shows that significant wave height can exceed 5 m in the eastern and central basins. The long-term lake level data show that storm surge can reach up to 3 m in eastern Lake Erie. Owing its shallow depth, Lake Erie frequently experiences seiching motions, the low frequency oscillations that are initiated by storm surge. The seiches whose first mode of oscillations has a period of nearly 14.2 hours can last from several hours to days. In this study, the Lake Erie potential for power generation, primarily using storm surge and seiche and also waves are assessed. Given the cyclic lake level variations due to storm-induced seiching, a concept similar to that of tidal range development is utilized to assess the potential of storm surge and seiche energy harvesting mechanisms for power generation. In addition, wave energy resources of the Lake is characterized -. To achieve these objectives, the following steps are taken : (1) Frequency of occurrence for extreme storm surge and wave events is determined using extreme value analysis such as Peak-Over-Threshold method for the long-term water level and wave data; (2) Spatial and temporal variations of wave height, storm surge and seiche are characterized. The characterization is carried out using the wave and storm surge outputs from numerical simulation of a number of historical extreme events. The coupled ADCIRC and SWAN model is utilized for the modeling; (3) Assessment of the potentials for marine renewable power generation in Lake Erie is made. The approach can be extended to the other lakes in the Great Lakes region.

    Water clarity is a reliable indicator of lake productivity and an ideal metric of regional water quality. Clarity is an indicator of other water quality variables including chlorophyll-a, total phosphorus and trophic status; however, unlike these metrics, clarity can be accurately and efficiently estimated remotely on a regional scale. Remote sensing is useful in regions containing a large number of lakes that are cost prohibitive to monitor regularly using traditional field methods. Field-assessed lakes generally are easily accessible and may represent a spatially irregular, non-random sample of a region. We developed a remote monitoring program for Maine lakes >8 ha (1511 lakes) to supplement existing field monitoring programs. We combined Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) brightness values for TM bands 1 (blue) and 3 (red) to estimate water clarity (secchi disk depth) during 1990–2010. Although similar procedures have been applied to Minnesota and Wisconsin lakes, neither state incorporates physical lake variables or watershed characteristics that potentially affect clarity into their models. Average lake depth consistently improved model fitness, and the proportion of wetland area in lake watersheds also explained variability in clarity in some cases. Nine regression models predicted water clarity (R2 = 0.69–0.90) during 1990–2010, with separate models for eastern (TM path 11; four models) and western Maine (TM path 12; five models that captured differences in topography and landscape disturbance. Average absolute difference between model-estimated and observed secchi depth ranged 0.65–1.03 m. Eutrophic and mesotrophic lakes consistently were estimated more accurately than oligotrophic lakes. Our results show that TM bands 1 and 3 can be used to estimate regional lake water clarity outside the Great Lakes Region and that the accuracy of estimates is improved with additional model variables that reflect

    Contiguous floodplain lakes ('lakes') have historically been used as study units for comparative studies of limnological variables that vary within lakes. The hierarchical nature of these studies implies that study variables may be correlated within lakes and that covariate associations may differ not only among lakes but also by spatial scale. We evaluated the utility of treating lakes as study units for limnological variables that vary within lakes based on the criteria of important levels of among-lake variation in study variables and the observation of covariate associations that vary among lakes. These concerns were selected, respectively, to ensure that lake signatures were distinguishable from within-lake variation and that lake-scale effects on covariate associations might provide inferences not available by ignoring those effects. Study data represented chlorophyll a (CHL) and inorganic suspended solids (ISS) data from lakes within three reaches of the Upper Mississippi River. Sampling occurred in summer from 1993 through 2005 (except 2003); numbers of lakes per reach varied from 7 to 19, and median lake area varied from 53 to 101 ha. CHL and ISS levels were modelled linearly, with lake, year and lake x year effects treated as random. For all reaches, the proportions of variation in CHL and ISS attributable to differences among lakes (including lake and lake x year effects) were substantial (range: 18%-73%). Finally, among-lake variation in CHL and ISS was strongly associated with covariates and covariate effects that varied by lakes or lake-years (including with vegetation levels and, for CHL, log(ISS)). These findings demonstrate the utility of treating floodplain lakes as study units for the study of limnological variables and the importance of addressing hierarchy within study designs when making inferences from data collected within floodplain lakes.

    The aim of this study is the analysis of trend in the trophic level evolution in clear deep lakes which, being characterised by good quality state, are important socio- economic resources for their regions. The selected lakes are situated in Europe (Garda, Maggiore, Constance and Vättern), North America (Michigan) and Africa (Malawi and Tanganyika) and cover a range of eco- regions (continental, perialpine, boreal, rift valley) distributed globally.To evaluate trophic level tendency we mainly focused on chlorophyll-a concentrations (chl-a) which is a direct proxy of trophic status. The chl-a concentrations were obtained from 5216 cloud-free MERIS imagery from 2002 to 2012.The 'GLaSS RoIStats tool' available within the GLaSS project was used to extract chl-a in a number of region of interests (ROI) located in pelagic waters as well as some few other stations depending on lakes morphology. For producing the time-series trend, these extracted data were analysed with the Seasonal Kendall test.The results overall show almost stable conditions with a slight increase in concentration for lakes Maggiore, Constance, and the Green Bay of Lake Michigan; a slight decrease for lakes Garda and Tanganyika and absolutely stable conditions for lakes Vättern and Malawi.The results presented in this work show the great capability of MERIS to perform trend tests analysis on trophic status with focus on chl-a concentration. Being chl-a also a key parameter in water quality monitoring plans, this study also supports the managing practices implemented worldwide for using the water of the lakes.

    Alternative stable states in shallow lakes are typically characterized by submerged macrophyte (clear-water state) or phytoplankton (turbid state) dominance. However, a clear-water state may occur in eutrophic lakes even when macrophytes are absent. To test whether sediment algae could cause a regime shift in the absence of macrophytes, we developed a model of benthic (periphyton) and planktonic (phytoplankton) primary production using parameters derived from a shallow macrophyte-free lake that shifted from a turbid to a clear-water state following fish removal (biomanipulation). The model includes a negative feedback effect of periphyton on phosphorus (P) release from sediments. This in turn induces a positive feedback between phytoplankton production and P release. Scenarios incorporating a gradient of external P loading rates revealed that (1) periphyton and phytoplankton both contributed substantially to whole-lake production over a broad range of external P loading in a clear-water state; (2) during the clear-water state, the loss of benthic production was gradually replaced by phytoplankton production, leaving whole-lake production largely unchanged; (3) the responses of lakes to biomanipulation and increased external P loading were both dependent on lake morphometry; and (4) the capacity of periphyton to buffer the effects of increased external P loading and maintain a clear-water state was highly sensitive to relationships between light availability at the sediment surface and the of P release. Our model suggests a mechanism for the persistence of alternative states in shallow macrophyte-free lakes and demonstrates that regime shifts may trigger profound changes in ecosystem structure and function.

    Understanding fish habitat use is important in determining conditions that ultimately affect fish energetics, growth and reproduction. Great Lakes lake whitefish (Coregonus clupeaformis) have demonstrated dramatic changes in growth and life history traits since the appearance of dreissenid mussels in the Great Lakes, but the role of habitat occupancy in driving these changes is poorly understood. To better understand temporal changes in lake whitefish depth of capture (Dw), we compiled a database of fishery-independent surveys representing multiple populations across all five Laurentian Great Lakes. By demonstrating the importance of survey design in estimating Dw, we describe a novel method for detecting survey-based bias in Dw and removing potentially biased data. Using unbiased Dw estimates, we show clear differences in the pattern and timing of changes in lake whitefish Dw between our reference sites (Lake Superior) and those that have experienced significant benthic food web changes (lakes Michigan, Huron, Erie and Ontario). Lake whitefish Dw in Lake Superior tended to gradually shift to shallower waters, but changed rapidly in other locations coincident with dreissenid establishment and declines in Diporeia densities. Almost all lake whitefish populations that were exposed to dreissenids demonstrated deeper Dw following benthic food web change, though a subset of these populations subsequently shifted to more shallow depths. In some cases in lakes Huron and Ontario, shifts towards more shallow Dw are occurring well after documented Diporeia collapse, suggesting the role of other drivers such as habitat availability or reliance on alternative prey sources.

    Lake Washington, in the midst of the greater Seattle metropolitan area of the Puget Sound region (fig. 1), is an exceptional commercial, recreational, and esthetic resource for the region . In the past 130 years, Lake Washington has been changed from a " wild " lake in a wilderness setting to a regulated lake surrounded by a growing metropolis--a transformation that provides an unusual opportunity to study changes to a lake's shoreline and hydrologic characteristics -resulting from urbanization.

    Organic and inorganic fractions of sediment collected from the bottom of Walker Lake, Nevada, have been dated by carbon-14 techniques. Sedimentation rates and the organic-carbon content of the sediment were correlated with climatic change. The cold climate between 25,000 and 21,000 years ago caused little runoff, snow accumulation on the mountains, and rapid substantial glacial advances; this period of cold climate resulted in a slow sedimentation rate (0.20 millimeter per year) and in a small organic-carbon content in the sediment. Also, organic-carbon accumulation rates in the lake during this period were slow. The most recent period of slow sedimentation rate and small organic-carbon content occurred between 10,000 and 5500 years ago, indicative of low lake stage and dry climatic conditions. This period of dry climate also was evidenced by dry conditions for Lake Lahontan in Nevada and Searles Lake in California, as cited in the literature. Walker Lake filled rapidly with water between 5500 and 4500 years ago. The data published in this report was not produced under an approved Site Investigation Plan (SIP) or Study Plan (SP) and will not be used in the licensing process. 10 refs., 3 figs., 2 tabs

    Full Text Available Cuicocha is a young volcano adjacent to the inactive Pleistocene Cotacachi volcano complex, located in the western cordilleras of the Ecuadorian Andes. A series of eruptions with intensive ash emission and collapse of the caldera occurred around 4500–3000 y BP. A crater 3.2 km in diameter and a maximum depth of 450 m was formed. Further eruptions of the volcano occurred 1300 y BP and formed four smaller domes within the caldera. Over the last few hundred years, a caldera lake has developed, with a maximum depth of 148 m. The lake water is characterized by sodium carbonate with elevated concentrations of manganese, calcium and chloride. Nowadays, an emission of gases, mainly CO2, and an input of warm spring water occur in Lake Cuicocha. The zone of high activity is in the western basin of the lake at a depth of 78 m, and continuous gas emissions with sediment resuspension were observed using sonar. In the hypolimnion of the lake, CO2 accumulation occurs up to 0.2% saturation, but the risk of a limnic eruption can be excluded at present. The lake possesses monomictic stratification behaviour, and during overturn an intensive gas exchange with the atmosphere occurs. Investigations concerning the sedimentation processes of the lake suggest only a thin sediment layer of up to 10–20 cm in the deeper lake basin; in the western bay, in the area of gas emissions, the lake bottom is partly depleted of sediment in the form of holes, and no lake colmation exists. Decreases in the lake water level of about 30 cm y−1 indicate a percolation of water into fractures and fissures of the volcano, triggered by a nearby earthquake in 1987.

  3. A Synoptic Climatology of Heavy Rain Events in the Lake Eyre and Lake Frome Catchments

    Full Text Available The rare occasions when Lake Eyre in central, southern Australia fills with water excite great interest and produce major ecological responses. The filling of other smaller lakes such as Lake Frome, have less impact but can contribute important information about the current and past climates of these arid regions. Here, the dominant synoptic systems responsible for heavy rainfall over the catchments of Lake Eyre and Lake Frome since 1950 are identified and compared. Heavy rain events are defined as those where the mean catchment rainfall for 24 hours reaches a prescribed threshold. There were 25 such daily events at Lake Eyre and 28 in the Lake Frome catchment. The combination of a monsoon trough at mean sea level and a geopotential trough in the mid-troposphere was found to be the synoptic system responsible for the majority of the heavy rain events affecting Lake Eyre and one in five of the events at Lake Frome. Complex fronts where subtropical interactions occurred with Southern Ocean fronts also contributed over 20% of the heavy rainfall events in the Frome catchment. Surface troughs without upper air support were found to be associated with 10% or fewer of events in each catchment, indicating that mean sea level pressure analyses alone do not adequately capture the complexity of the heavy rainfall events. At least 80% of the heavy rain events across both catchments occurred when the Southern Oscillation Index (SOI was in its positive phase, and for Lake Frome, the SOI exceeded +10 on 60% of occasions, suggesting that the background atmospheric state in the Pacific Ocean was tilted towards La Niña. Hydrological modeling of the catchments suggests that the 12-month running mean of the soil moisture in a sub-surface layer provides a low frequency filter of the precipitation and matches measured lake levels relatively well.

    Dendrochronology methods are used to analyze the characteristics of Tamarix spp. growth in Bosten Lake. Based on the long-term annual and monthly data of lake level, this paper models the relationship between ring width of Tamarix spp. and lake level change. The sensitivity index is applied to determine the rational change range of lake level for protecting the Tamarix spp. growth. The results show that :( 1) the annual change of lake level in Bosten Lake has tree evident stages from 1955 to 2012. The monthly change of lake level has two peak values and the seasonal change is not significant; (2) the average value of radical width of Tamarix spp. is 3.39mm. With the increment of Tamarix spp. annual growth , the average radical width has a decreasing trend, which is similar to the annual change trend of lake level in the same years ;( 3) the response of the radical width of Tamarix spp. to annual change of lake level is sensitive significantly. When the lake level is 1045.66m, the Sk value of radical width of Tamarix spp. appears minimum .when the lake level is up to1046.27m, the Sk value is maximum. Thus the sensitivity level of radical width of Tamarix spp. is 1045.66- 1046.27m which could be regarded as the rational lake level change range for protecting the Tamarix spp. growth.

    Hydrologic and ecologic changes in the Lake Chad Basin are shown in this Oct 1992 photograph. In space photo documentation, Lake Chad was at its greatest area extent (25,000 sq. km.) during Gemini 9 in June 1966 (see S66-38444). Its reduction during the severe droughts from 1968 to 1974 was first noted during Skylab (1973-1974). After the drought began again in 1982, the lake reached its minimum extent (1,450 sq. km.) in Space Shuttle photographs taken in 1984 and 1985. In this STS-52 photograph, Lake Chad has begun to recover. The area of the open water and interdunal impoundments in the southern basin (the Chari River Basin) is estimated to be 1,900 to 2100 sq. km. Note the green vegetation in the valley of the K'Yobe flow has wetted the northern lake basin for the first time in several years. There is evidence of biomass burning south of the K'Yobe Delta and in the vegetated interdunal areas near the dike in the center of the lake. Also note the dark 'Green Line' of the Sahel (the g

    After a decade of extensive dismantling and reconstruction, changes in the downstream refining and marketing side of the petroleum industry have progressed to the point where downstream assets are once again considered to be among the strongest and most vital parts of the industry. Merchandising has become a way of life in gasoline service stations to the point where the service station of the 21. century will likely carry mass-consumption items from panty hose to sandwiches in addition to gasoline. Petro-Canada is in the forefront of rolling out the new-image service stations, while high traffic Esso locations are adding cafes serving doughnuts, muffins, bagels, soup and sandwiches in partnership with the Tim Horton's chain. In Canada, Quebec is way ahead of the other provinces in setting the high tone in the business of catering to consumers on wheels as demonstrated by the 1,932 retail sites of 'Couche-Tard', a name synonymous with gas pumps, fresh coffee and the myriad items offered in traditional convenience stores. With a total of 1,693 stores in Canada, 239 in the United States, 13,000 plus employees and more than 800 gas pumps (80 of them branded to in-house gasoline) Couche-Tard is the ninth largest convenience retailer in North America. The article describes the rise to prominence of the Couche-Tard empire, explains why circumstances in Quebec were ripe for this type of development, and offers a glimpse into the future of the likely further development of the retail gasoline market in the rest of Canada.

    The R408W mutation in the phenylalanine hydroxylase gene (PAH) is associated with haplotype 2.3 (RFLP haplotype 2, VNTR 3 of the HindIII system) in most European populations. Another chromosome, first observed in Quebec and then in northwest Europe, carries R408W on haplotype 1.8. The occurrence of the R408W mutation on two different PKU chromosomes could be the result of intragenic recombination, recurrent mutation or gene conversion. In this study, we analyzed both normal and R408W chromosomes carrying 1.8 and 2.3 haplotypes in Quebec and European populations; we used the TCTA{sub (n)} short tandem repeat sequence (STR) at the 5{prime} end of the PAH gene and the HindIII VNTR system at the 3{prime} end of the PAH gene to characterize chromosomes. Fourteen of sixteen R408W chromosomes from {open_quotes}Celtic{close_quotes} families in Quebec and the United Kingdom (UK) harbor a 244 bp STR allele; the remaining two chromosomes, carry a 240 bp or 248bp STR allele. Normal chromosomes (n=18) carry the 240 bp STR allele. R408W chromosomes are different from mutant H1.8 chromosomes; mutant H2.3 carries the 240 bp STR allele (14 of 16 chromosomes) or the 236 allele (2 of 16 chromosomes). The HindIII VNTR comprises variable numbers of 30 bp repeats (cassettes); the repeats also vary in nucleotide sequence. Variation clusters toward the 3{prime} end of cassettes and VNTRs. VNTR 3 alleles on normal H2 (n=9) and mutant R408W H2 (n=19) chromosomes were identical. VNTR 8 alleles on normal H1 chromosomes (n=9) and on R408W H1 chromosomes (n=15) differ by 1 bp substitution near the 3{prime} end of the 6th cassette. In summary, the mutant H1.8 chromosome harboring the R408W mutation has unique features at both the 5{prime} and 3{prime} end of the gene that distinguish it from the mutant H2.3 and normal H1.8 and H2.3 counterparts. The explanation for the occurrence of R408W on two different PAH haplotypes is recurrent mutation affecting the CpG dinucleotide in PAH codon 408.

  11. Influence of permafrost on lake terraces of Lake Heihai (NE Tibetan Plateau)

    2013-04-01

    The Tibetan Plateau (TP) is one of the key regions for climatic global change. Besides the poles the TP is the third highest storage of frozen water in glaciers. Here global warming is three times higher than in the rest of the world. Additionally the TP provides water for billions of people and influences the moisture availability from the Indian and East Asian monsoon systems. During the Holocene extent and intensity of the monsoonal systems changed. Hence, in the last decades, a lot of work was done to reconstruct timing and frequency of monsoonal moisture, to understand the past and give a better forecast for the future. Comparative workings often show very heterogeneous patterns of timing and frequency of the Holocene precipitation and temperature maximum, emphasizing the local importance of catchment dynamics. In this study we present first results of lake Heihai (36°N, 93°15'E, 4500m a.s.l.), situated at the north-eastern border of the TP. The lake is surrounded by a broad band of near-shore lake sediments, attesting a larger lake extent in the past. These sediments were uplifted by permafrost, reaching nowadays heights ca. +8 meters above present lake level. Due to the uplift one of the main inflows was blocked and the whole hydrology of the catchment changed. To quantify the uplift of permafrost Hot Spot Analysis were accomplished at a DEM of the near-shore area. As a result regions of high permafrost uplift and those which mirror the original height of lake ground were revealed. The most obvious uplift took place in the northern and western part of the lake, where the four uplift centers are located. In contrast the southern and eastern areas show a rather degraded pattern (probably by fluvial erosion, thermokarst, etc.). The ancient lake bottom, without permafrost uplift was estimated to be 4-6 meters above the modern lake level. For a better understanding of permafrost interaction inside the terrace bodies a 5m sediment profile was sampled and

    Satellites provide a view from space of changes on the Earth's surface. This series of images from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) aboard the Orbview-2 satellite shows the dramatic change in the color of Lake Michigan during the summer. The bright color that appears in late summer is probably caused by calcium carbonate-chalk-in the water. Lake Michigan always has a lot of calcium carbonate in it because the floor of the lake is limestone. During most of the year the calcium carbonate remains dissolved in the cold water, but at the end of summer the lake warms up, lowering the solubility of calcium carbonate. As a result, the calcium carbonate precipitates out of the water, forming clouds of very small solid particles that appear as bright swirls from above. The phenomenon is appropriately called a whiting event. A similar event occured in 1999, but appears to have started later and subsided earlier. It is also possible that a bloom of the algae Microcystis is responsible for the color change, but unlikely because of Lake Michigan's depth and size. Microcystis blooms have occured in other lakes in the region, however. On the shore of the lake it is possible to see the cities of Chicago, Illinois, and Milwaukee, Wisconsin. Both appear as clusters of gray-brown pixels. Image courtesy the SeaWiFS Project, NASA/Goddard Space Flight Center, and ORBIMAGE

    This report presents documentation and a user's manual for the program LAKE-0, a mathematical model of nuclides transfer in lake scenarios. Mathematical equations and physical principles used to develop the code are presented in section 2. The program use is presented in section 3 including input data sets and output data. Section 4 presents two example problems, and some results. The complete program listing including comments is presented in Appendix A. Nuclides are assumed to enter the lake via atmospheric deposition and carried by the water runoff and the dragged sediments from the adjacent catchment. The dynamics of the nuclides inside the lake is based in the model proposed by Codell (11) as modified in (5). The removal of concentration from the lake water is due to outflow from the lake and to the transfer of activity to the bottom sediments. The model has been applied to the Esthwaite Water (54 degree 21 minute N, 03 degree 00 minute W at 65 m. asl.) in the frame of the VAMP Aquatic Working Group (8) and to Devoke Water (54 degree 21 minute 5'N, 03 degree, 18 minute W at 230 m. asl.)

    Full Text Available A Lake Multi-biotic Integrity Index (LMII for the China’s second largest interior lake (Dongting Lake was developed to assess the water quality status using algal and macroinvertebrate metrics. Algae and benthic macroinvertebrate assemblages were sampled at 10 sections across 3 subregions of Dongting Lake. We used a stepwise process to evaluate properties of candidate metrics and selected ten for the LMII: Pampean diatom index, diatom quotient, trophic diatom index, relative abundance diatoms, Margalef index of algae, percent sensitive diatoms, % facultative individuals, % Chironomidae individuals, % predators individuals, and total number of macroinvertebrate taxa. We then tested the accuracy and feasibility of the LMII by comparing the correlation with physical-chemical parameters. Evaluation of the LMII showed that it discriminated well between reference and impaired sections and was strongly related to the major chemical and physical stressors (r = 0.766, P<0.001. The re-scored results from the 10 sections showed that the water quality of western Dongting Lake was good, while that of southern Dongting Lake was relatively good and whereas that of eastern Dongting Lake was poor. The discriminatory biocriteria of the LMII are suitable for the assessment of the water quality of Dongting Lake. Additionally, more metrics belonging to habitat, hydrology, physics and chemistry should be considered into the LMII, so as to establish comprehensive assessment system which can reflect the community structure of aquatic organisms, physical and chemical characteristics of water environment, human activities, and so on.

    Constraints on lake communities are complex and are usually studied by using limited combinations of variables derived from measurements within or adjacent to study waters. While informative, results often provide limited insight about magnitude of simultaneous influences operating at multiple scales, such as lake- vs. watershed-scale. To formulate comparisons of such contrasting influences, we explored factors controlling the abundance of predominant aquatic invertebrates in 75 shallow lakes in western Minnesota, USA. Using robust regression techniques, we modeled relative abundance of Amphipoda, small and large cladocera, Corixidae, aquatic Diptera, and an aggregate taxon that combined Ephemeroptera-Trichoptera-Odonata (ETO) in response to lake- and watershed-scale characteristics. Predictor variables included fish and submerged plant abundance, linear distance to the nearest wetland or lake, watershed size, and proportion of the watershed in agricultural production. Among-lake variability in invertebrate abundance was more often explained by lake-scale predictors than by variables based on watershed characteristics. For example, we identified significant associations between fish presence and community type and abundance of small and large cladocera, Amphipoda, Diptera, and ETO. Abundance of Amphipoda, Diptera, and Corixidae were also positively correlated with submerged plant abundance. We observed no associations between lake-watershed variables and abundance of our invertebrate taxa. Broadly, our results seem to indicate preeminence of lake-level influences on aquatic invertebrates in shallow lakes, but historical land-use legacies may mask important relationships. PMID:22970275

    Payette Lake was studied during water years 1995-96 to determine the 20.5-square-kilometer lake's assimilative capacity for nutrients and, thus, its eutrophication potential. The study included quantification of hydrologic and nutrient budgets, characterization of water quality in the limnetic and littoral zones, development of an empirical nutrient load/lake response model, and estimation of the limnological effects of a large-scale forest fire in the lake's 373-square-kilometer watershed during the autumn of 1994. Streamflow from the North Fork Payette River, the lake's primary tributary, delivered about 73 percent of the lake's inflow over the 2 years. Outflow from the lake, measured since 1908, was 128 and 148 percent of the long-term average in 1995 and 1996, respectively. The larger volumes of outflow reduced the long-term average water-

    In comparison with marine environments, the occurrence of microplastics in freshwater environments is less understood. In the present study, we investigated microplastic pollution levels during 2015 in Taihu Lake, the third largest Chinese lake located in one of the most developed areas of China. The abundance of microplastics reached 0.01 × 10(6)-6.8 × 10(6) items/km(2) in plankton net samples, 3.4-25.8 items/L in surface water, 11.0-234.6 items/kg dw in sediments and 0.2-12.5 items/g ww in Asian clams (Corbicula fluminea). The average abundance of microplastics was the highest in plankton net samples from the southeast area of the lake and in the sediments from the northwest area of the lake. The northwest area of the lake was the most heavily contaminated area of the lake, as indicated by chlorophyll-α and total phosphorus. The microplastics were dominated by fiber, 100-1000 μm in size and cellophane in composition. To our best knowledge, the microplastic levels measured in plankton net samples collected from Taihu Lake were the highest found in freshwater lakes worldwide. The ratio of the microplastics in clams to each sediment sample ranged from 38 to 3810 and was negatively correlated to the microplastic level in sediments. In brief, our results strongly suggest that high levels of microplastics occurred not only in water but also in organisms in Taihu Lake. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Depth is usually considered the main driver of Lake Trout intraspecific diversity across lakes in North America. Given that Great Bear Lake is one of the largest and deepest freshwater systems in North America, we predicted that Lake Trout intraspecific diversity to be organized along a depth axis within this system. Thus, we investigated whether a deep-water morph of Lake Trout co-existed with four shallow-water morphs previously described in Great Bear Lake. Morphology, neutral genetic variation, isotopic niches, and life-history traits of Lake Trout across depths (0-150 m) were compared among morphs. Due to the propensity of Lake Trout with high levels of morphological diversity to occupy multiple habitat niches, a novel multivariate grouping method using a suite of composite variables was applied in addition to two other commonly used grouping methods to classify individuals. Depth alone did not explain Lake Trout diversity in Great Bear Lake; a distinct fifth deep-water morph was not found. Rather, Lake Trout diversity followed an ecological continuum, with some evidence for adaptation to local conditions in deep-water habitat. Overall, trout caught from deep-water showed low levels of genetic and phenotypic differentiation from shallow-water trout, and displayed higher lipid content (C:N ratio) and occupied a higher trophic level that suggested an potential increase of piscivory (including cannibalism) than the previously described four morphs. Why phenotypic divergence between shallow- and deep-water Lake Trout was low is unknown, especially when the potential for phenotypic variation should be high in deep and large Great Bear Lake. Given that variation in complexity of freshwater environments has dramatic consequences for divergence, variation in the complexity in Great Bear Lake (i.e., shallow being more complex than deep), may explain the observed dichotomy in the expression of intraspecific phenotypic diversity between shallow- vs. deep-water habitats

    The extreme North American winter storm of November 2014 triggered a record lake effect snowfall (LES) event in southwest New York. This study examined the evaporation from Lake Erie during the record lake effect snowfall event, November 17th-20th, 2014, by reconstructing heat fluxes and evaporation rates over Lake Erie using the unstructured grid, Finite-Volume Community Ocean Model (FVCOM). Nine different model runs were conducted using combinations of three different flux algorithms: the Met Flux Algorithm (COARE), a method routinely used at NOAA's Great Lakes Environmental Research Laboratory (SOLAR), and the Los Alamos Sea Ice Model (CICE); and three different meteorological forcings: the Climate Forecast System version 2 Operational Analysis (CFSv2), Interpolated observations (Interp), and the High Resolution Rapid Refresh (HRRR). A few non-FVCOM model outputs were also included in the evaporation analysis from an atmospheric reanalysis (CFSv2) and the large lake thermodynamic model (LLTM). Model-simulated water temperature and meteorological forcing data (wind direction and air temperature) were validated with buoy data at three locations in Lake Erie. The simulated sensible and latent heat fluxes were validated with the eddy covariance measurements at two offshore sites; Long Point Lighthouse in north central Lake Erie and Toledo water crib intake in western Lake Erie. The evaluation showed a significant increase in heat fluxes over three days, with the peak on the 18th of November. Snow water equivalent data from the National Snow Analyses at the National Operational Hydrologic Remote Sensing Center showed a spike in water content on the 20th of November, two days after the peak heat fluxes. The ensemble runs presented a variation in spatial pattern of evaporation, lake-wide average evaporation, and resulting cooling of the lake. Overall, the evaporation tended to be larger in deep water than shallow water near the shore. The lake-wide average evaporations

    A basin-scale hydrologic-energy balance model that integrates modern climatological, hydrological, and hypsographic observations was developed for the modern Lake Titicaca watershed (northern Altiplano, South America) and operated under variable conditions to understand controls on post-glacial changes in lake level. The model simulates changes in five environmental variables (air temperature, cloud fraction, precipitation, relative humidity, and land surface albedo). Relatively small changes in three meteorological variables (mean annual precipitation, temperature, and/or cloud fraction) explain the large mid-Holocene lake-level decrease ({proportional_to}85 m) inferred from seismic reflection profiling and supported by sediment-based paleoproxies from lake sediments. Climatic controls that shape the present-day Altiplano and the sediment-based record of Holocene lake-level change are combined to interpret model-derived lake-level simulations in terms of changes in the mean state of ENSO and its impact on moisture transport to the Altiplano.

  6. In-Lake Processes Offset Increased Terrestrial Inputs of Dissolved Organic Carbon and Color to Lakes

    Increased color in surface waters, or browning, can alter lake ecological function, lake thermal stratification and pose difficulties for drinking water treatment. Mechanisms suggested to cause browning include increased dissolved organic carbon (DOC) and iron concentrations, as well as a shift to more colored DOC. While browning of surface waters is widespread and well documented, little is known about why some lakes resist it. Here, we present a comprehensive study of Mälaren, the third largest lake in Sweden. In Mälaren, the vast majority of water and DOC enters a western lake basin, and after approximately 2.8 years, drains from an eastern basin. Despite 40 years of increased terrestrial inputs of colored substances to western lake basins, the eastern basin has resisted browning over this time period. Here we find the half-life of iron was far shorter (0.6 years) than colored organic matter (A420 ; 1.7 years) and DOC as a whole (6.1 years). We found changes in filtered iron concentrations relate strongly to the observed loss of color in the western basins. In addition, we observed a substantial shift from colored DOC of terrestrial origin, to less colored autochthonous sources, with a substantial decrease in aromaticity (-17%) across the lake. We suggest that rapid losses of iron and colored DOC caused the limited browning observed in eastern lake basins. Across a wider dataset of 69 Swedish lakes, we observed greatest browning in acidic lakes with shorter retention times (< 1.5 years). These findings suggest that water residence time, along with iron, pH and colored DOC may be of central importance when modeling and projecting changes in brownification on broader spatial scales.

    Direct underwater video observations were made of the bottom substrates at 12 spawning grounds formerly used by lake trout Salvelinus namaycush in western Lake Huron to evaluate their present suitability for successful reproduction by lake trout. Nine locations examined north of Saginaw Bay in the northwestern end of the lake are thought to provide the best spawning habitat. The substrate at these sites consisted of angular rough cobble and rubble with relatively deep interstitial spaces (a?Y 0.5 m), small amounts of fine sediments, and little or no periphytic growth. Conditions at the three other sampling locations south of Saginaw Bay seemed much less suitable for successful reproduction based on the reduced area of high-quality substrate, shallow interstitial spaces, high infiltration of fine sediments, and greater periphytic growth.

    Temporal and spatial distributions of ground-water inflow to, and leakage from Lake Five-O, a softwater, seepage lake in northwestern Florida, were evaluated using hydrologic data and simulation models of the shallow ground-water system adjacent to the lake. The simulation models indicate that ground-water inflow to the lake and leakage from the lake to the ground-water system are the dominant components in the total inflow (precipitation plus ground-water inflow) and total outflow (evaporation plus leakage) budgets of Lake Five-O. Simlulated ground-water inflow and leakage were approximately 4 and 5 times larger than precipitation inputs and evaporative losses, respectively, during calendar years 1989-90. Exchanges of water between Lake Five-O and the ground-water system were consistently larger than atmospheric-lake exchanges. A consistent pattern of shallow ground-water inflow and deep leakage was also evident throughout the study period. The mean time of travel from ground-water that discharges at Lake Five-O (time from recharge at the water table to discharge at the lake) was estimated to be within a range of 3 to 6 years. Flow-path evaluations indicated that the intermediate confining unit probably has a negligible influence on the geochemistry of ground-water inflow to Lake Five-O. The hydrologic budgets and flow-path evaluations provide critical information for developing geochemical budgets for Lake Five-O and for improving the understanding of the relative importance of various processes that regulate the acid-neutralizing capacity of softwater seepage lakes in Florida.

    A field study was conducted in the lower Great Lakes to assess changes in spatial distribution and population structure of dreissenid mussel populations. More specifically, the westward range expansion of quagga mussel into western Lake Erie and toward Lake Huron was investigated and the shell size, density, and biomass of zebra and quagga mussel with depth in southern Lake Ontario in 1992 and 1995 were compared. In Lake Erie, quagga mussel dominated the dreissenid community in the eastern basin and zebra mussel dominated in the western basin. In southern Lake Ontario, an east to west gradient was observed with the quagga mussel dominant at western sites and zebra mussel dominant at eastern locations. Mean shell size of quagga mussel was generally larger than that of zebra mussel except in western Lake Erie and one site in eastern Lake Erie. Although mean shell size and our index of numbers and biomass of both dreissenid species increased sharply in southern Lake Ontario between 1992 and 1995, the increase in density and biomass was much greater for quagga mussels over the 3-year period. In 1995, zebra mussels were most abundant at 15 to 25 m whereas the highest numbers and biomass of quagga mussel were at 35 to 45 m. The quagga mussel is now the most abundant dreissenid in areas of southern Lake Ontario where the zebra mussel was once the most abundant dreissenid; this trend parallels that observed for dreissenid populations in the Dneiper River basin in the Ukraine.

    We previously demonstrated that there were significant differences in the egg thiamine content in lake trout Salvelinus namaycush fed two Lake Michigan prey fish (alewife Alosa pseudoharengus and bloater Coregonus hoyi). Lake trout fed alewives produced eggs low in thiamine, but it was unknown whether the consumption of alewives affected other nutritionally important components. In this study we investigated the fatty acid composition of lake trout eggs when females were fed diets that resulted in different egg thiamine concentrations. For 2 years, adult lake trout were fed diets consisting of four combinations of captured alewives and bloaters (100% alewives; 65% alewives, 35% bloaters; 35% alewives, 65% bloaters; and 100% bloaters). The alewife fatty acid profile had higher concentrations of arachidonic acid and total omega-6 fatty acids than the bloater profile. The concentrations of four fatty acids (cis-13, 16-docosadienoic, eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids) were higher in bloaters than in alewives. Although six fatty acid components were higher in lake trout eggs in 2001 than in 2000 and eight fatty acids were lower, diet had no effect on any fatty acid concentration measured in lake trout eggs in this study. Based on these results, it appears that egg fatty acid concentrations differ between years but that the egg fatty acid profile does not reflect the alewife-bloater mix in the diet of adults. The essential fatty acid content of lake trout eggs from females fed alewives and bloaters appears to be physiologically regulated and adequate to meet the requirements of developing embryos.
