    The late-Proterozoic Allard Lake ilmenite deposit is located in the Havre-Saint-Pierre anorthosite complex, part of the allochtonous polycyclic belt of the Grenville Province. Presently the world's largest Fe-Ti oxide deposit, it had a pre-mining amount in excess of 200 Mt at grades over 60 wt.% hemo-ilmenite. The main ore body is a funnel-shaped intrusion, measuring 1.03 × 1.10 km and 100-300 m-thick. Two smaller bodies are separated by faults and anorthosite. The ore is an ilmenite-rich norite (or ilmenitite) made up of hemo-ilmenite (Hem 22.6-29.4, 66.2 wt.% on average), andesine plagioclase (An 45-50), aluminous spinel and locally orthopyroxene. Whole-rock chemical compositions are controlled by the proportions of ilmenite and plagioclase ± orthopyroxene which supports the cumulate origin of the deposit. Ore-forming processes are further constrained by normal and reverse fractionation trends of Cr concentration in cumulus ilmenite that reveal multiple magma emplacements and alternating periods of fractional crystallization and magma mixing. Mixing of magmas produced hybrids located in the stability field of ilmenite resulted in periodic crystallization of ilmenite alone. The unsystematic differentiation trends in the Allard Lake deposit, arising from a succession of magma pulses, hybridisation, and the fractionation of hemo-ilmenite alone or together with plagioclase suggest that the deposit formed within a magma conduit. This dynamic emplacement mechanism associated with continuous gravity driven accumulation of Fe-Ti oxides and possibly plagioclase buoyancy in a fractionating ferrobasalt explains the huge concentration of hemo-ilmenite. The occurrence of sapphirine associated with aluminous spinel and high-alumina orthopyroxene (7.6-9.1 wt.% Al 2O 3) lacking exsolved plagioclase supports the involvement of a metamorphic overprint during the synchronous Ottawan orogeny, which is also responsible for strong textural equilibration and external granule of

    Full Text Available The results of dissolved GHG (CO2 and CH4 measurement campaigns carried out in Quebec (Canada during the open-water periods and under-ice in a newly created reservoir (Eastmain 1, a 25 year old reservoir (Robert-Bourassa and in three reference lakes are presented. While CO2 partial pressures varied with season with a net increase under the ice cover, CH4 partial pressures did not. We were able to extrapolate the highest CO2 partial pressures reached in the different studied systems just before ice break-up with high spring emission period. We then estimated the springtime CO2 fluxes and compared them to annual CO2 fluxes and GHG fluxes. Thus we clearly demonstrated that in our systems CH4 fluxes was of minor importance in the GHG emissions, CO2 fluxes representing around 90% of the annual fluxes. We also pointed out the importance of springtime emissions in the annual budget.

  3. Forensic fingerprinting and source identification of the 2008 Lake Temiskaming (Quebec) oil spill

    International Nuclear Information System (INIS)

    Many of the advances that have occurred in recent years in chemical fingerprinting of petroleum and hydrocarbons for environmental forensic processes have followed advances in petroleum geochemistry. This paper presented a practical case study which demonstrated the utility of detailed and integrated multi-criterion analytical approaches for fingerprinting, correlating and identifying suspected spills. In particular, the source of a waterborne oil spill of unknown origin on Lake Temiskaming, Quebec was identified by combining forensic fingerprinting and data interpretation techniques to characterize the chemical compositions of the spill. The product type was first identified by recognizing distribution patterns of bulk hydrocarbon groups such as oil n-alkanes and unresolved complex mixtures. Biomarker and extended suite of parent and alkylated polycyclic aromatic hydrocarbon (PAH) compounds were then quantified and their distribution profiles were compared. The conclusions were verified by determining several diagnostic ratios of source-specific marker compounds, in particular diagnostic ratios of target biomarker compounds. The input of background pyrogenic PAHs to the suspected spill source samples were identified. It was concluded that some water and soil samples were contaminated by a heavy diesel type fuel. The differences in fingerprints were attributed to weathering effects and input of pyrogenic PAHs. 37 refs., 6 tabs., 8 figs

  4. Anthropogenic Pb accumulation in forest soils from Lake Clair watershed: Duchesnay experimental forest (Quebec, Canada)

    International Nuclear Information System (INIS)

    Mineral soil horizons (Ae, Bhf1, Bhf2, Bf, BC and C) were carefully collected from two podzolic soil profiles in the Lake Clair watershed (Quebec) in order to assess anthropogenic trace metal accumulation. Petrographic and selective analyses were performed to establish the soil mineralogy and properties. Furthermore, a complete sequential extraction procedure has been applied to help understanding the complex chemical speciation of Pb in forest soils. Chemical speciation of Pb showed a strong vertical gradient: 85% of this metal is mainly partitioned in refractory minerals in the C-horizon whereas in the upper Bhf1 and Ae-horizons, less than 50% of Pb is associated with this fraction. In the Ae-horizon, for example, 35%, 30% and 12% of total Pb, respectively, is associated with the exchangeable, labile organic matter and amorphous Fe-Mn oxides fractions. The distribution of Pb and Cr in the studied forest soils mainly reflects progressive contamination of the watershed by anthropogenic atmospheric sources. The anthropogenic source is indicated by elevated Cr and Pb concentrations in the topsoil (Bhf and Ae) horizons and by strong negative correlation between 206Pb/207Pb ratios and total Pb concentrations. According to these isotopic values, penetration of anthropogenic Pb does not exceed 10 cm in both soil profiles. Below this depth, both Pb concentrations and isotopic ratios remain nearly constant and similar to values observed in pre-anthropogenic sediments from Lake Clair. These values are interpreted as the natural geochemical backgrounds of the watershed. Based on that behaviour, calculated anthropogenic Pb net inputs amounted to between 1.24 and 1.8 g/m2

  6. 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

    Directory of Open Access Journals (Sweden)

    Paul Brian Hamilton

    2015-09-01

    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

  7. Hydro-Quebec 2005 annual report : people with energy

    International Nuclear Information System (INIS)

    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

  8. Comparison of plant and animal diversity on new reservoir islands and established lake islands in the northern boreal forests of Quebec

    International Nuclear Information System (INIS)

    Species diversity of passerines, small mammals and woody plants were studied in new islands of the La Grande-3 hydroelectric reservoir in the northern forests of Quebec and compared with that of natural islands in two neighbouring lakes. Contrary to predictions that species diversity would be reduced on reservoir islands because of their relatively recent creation, in fact species animal diversity, richness and composition were similar in both island groups. Richness of woody plants on reservoir islands exceeded that on lake island, although the mean age of trees on lake islands was significantly higher than that on reservoir islands. It was suggested that the creation of reservoir islands may change insular pattern of wild fires, and that differences in plant diversity between island groups may have resulted from differences in fire cycle rather than from isolation alone. Animal communities composition, too, might be influenced after a fire, because of the differences in the colonizing capacity of plant and animal species. 42 refs., 4 tabs., 3 figs

  10. More damnation in Quebec

    International Nuclear Information System (INIS)

    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

    The literature reports that led to the current acceptance of New Quebec Crater (Chubb Crater) as an authentic impact crater are reviewed, and it is noted that, for reasons that are not entirely clear, a meteoritic origin for the New Quebec Crater achieved wider acceptance at an earlier data than for the Lake Bosumtwi Crater, for which petrographic and chemical evidence is more abundant and compelling. The petrography of two impact melt samples from the New Quebec Crater was investigated, and new evidence is obtained on the degrees of shock metamorphism affecting the accessory minerals such as apatite, sphene, magnetite, and zircon.

    International Nuclear Information System (INIS)

    The pros and cons of the potential privatisation of Hydro-Quebec were discussed. 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

    1997-06-01

    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.

  14. Anorthosite Magma Revisited: Field and Petrographic Evidence From the CRUML Belt, Grenville Province, Quebec

    Science.gov (United States)

    Dymek, R. F.

    2004-05-01

    . Independent evidence for the presence of water in the evolution of the CRUML-belt plutons is provided by the widespread occurrence of biotite. Extensive reverse zoning in many individual plag crystals also can be explained by the involvement of water. The presence of identical features elsewhere in Quebec (e.g., in the Allard Lake massif) confirms that they are not unique to anorthosites of the CRUML belt, and may be more widespread than realized. The present author concludes, reluctantly, that the anorthosite dikes do not represent magma in the traditional sense but rather correspond to cumulate materials mobilized in the presence of an aqueous grain-boundary film. In this scenario, the dynamic environment of the upward-moving magmatic diapir caused expulsion of the putative aqueous fluid, forcing it into zones that led to "hyrofracturing" of the LA concomitant with dike emplacement.

    Trudeau, Jean-Bernard; Desjardins, Pierre; Dion, Alain

    2015-01-01

    Until recently, Quebec was the first to have regulated the practice of psychotherapy through law adopted in 2009. The law emerged following 30 years of efforts and inter-professional discussions that led to a consensus by an expert committee presided by Dr Jean-Bernard Trudeau in 2005. In this essay, Dr Jean-Bernard Trudeau, general practitioner, and two psychiatrist and psychologist colleagues, who have participated to the expert committee or have been involved more recently in the implementation of law no 21 in Quebec, relate the main landmarks and moments in the regulation of the practice in psychotherapy following this inter-professional consensus that was translated in the law 21. They relate particularly the last ten years that have led to the adoption of law 21 in 2009, following two parliamentary commission after the Trudeau report. They underline how the practice of psychotherapy is integrated in the professional system and submitted to strict regulation. It includes regulations for obtaining the license of psychotherapist and for maintaining competence. Guidelines emerging from continuous inter-professional discussions for the application of the law and of its regulation in the public and private sectors are produced by the Quebec Professions Office. The definition of psychotherapy that was reached by consensus is not limited to the treatment of mental disorders and is distinguished from other intervention in the area of human relations. Continuous training is mandatory and is implemented on one hand by the Order of the psychologists for the psychologists and other professionals practicing psychotherapy and on the other hand the College of physicians for physician practicing psychotherapy. The authors finally described the interdisciplinary advisory council for the practice of psychotherapy that the legislator has foreseen as an external mechanism to insure the conformity of regulation with the spirit of the law and to give opinions to the various

    Quebec's commitment to the obligations of the Kyoto Protocol and the United Nations Framework Convention on Climate Change (UNFCC) was discussed. Quebec has shown leadership on the Canadian and international scene by making a firm pledge to reduce its share of atmospheric emissions while contributing to the world effort. In 1995, Quebec published its first action plan for the implementation of UNFCC. The action plan focused mainly on stabilizing greenhouse gas emissions (GHGs) in Quebec through the adoption of voluntary measures. Thereafter, in 2000, the government of Quebec set up a second more ambitious action plan to control and reduce its emissions of GHGs. In 2001, Quebec adhered to the New England Governors and Eastern Canadian Premiers Climate Change Action Plan, a concerted gesture by states and provinces to address the climatic change issue.This plan includes all branches of industry and provides a regional base on which participating governments can collaborate. This report described Quebec's performance in the transportation sector. Use of public transit increased by 8 per cent in 5 years, despite a strong competition with cars. Quebec is also a leader in hydroelectricity. As a result, Quebec produces nearly half the GHGs per capita than the Canadian average. In addition, it can offer its citizens stable electricity prices which are amongst the lowest in North America. This report also discussed Quebec's adoptions of energy efficiency measures, wind energy, and GHG reduction technologies that include recycling carbon dioxide; biofuels; electric cars; the Ouranos initiative on climate change and climate change monitoring stations in the Arctic. figs.

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.

  12. Hydro-Quebec's Strategic Plan 2002-2006 : summary

    International Nuclear Information System (INIS)

    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

  13. Hydro-Quebec looks to integrated development of Quebec and its regions

    International Nuclear Information System (INIS)

    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

  14. Human genetics: lessons from Quebec populations.

    Scriver, C R

    2001-01-01

    The population of Quebec, Canada (7.3 million) contains approximately 6 million French Canadians; they are the descendants of approximately 8500 permanent French settlers who colonized Nouvelle France between 1608 and 1759. Their well-documented settlements, internal migrations, and natural increase over four centuries in relative isolation (geographic, linguistic, etc.) contain important evidence of social transmission of demographic behavior that contributed to effective family size and population structure. This history is reflected in at least 22 Mendelian diseases, occurring at unusually high prevalence in its subpopulations. Immigration of non-French persons during the past 250 years has given the Quebec population further inhomogeneity, which is apparent in allelic diversity at various loci. The histories of Quebec's subpopulations are, to a great extent, the histories of their alleles. Rare pathogenic alleles with high penetrance and associated haplotypes at 10 loci (CFTR, FAH, HBB, HEXA, LDLR, LPL, PAH, PABP2, PDDR, and SACS) are expressed in probands with cystic fibrosis, tyrosinemia, beta-thalassemia, Tay-Sachs, familial hypercholesterolemia, hyperchylomicronemia, PKU, oculopharyngeal muscular dystrophy, pseudo vitamin D deficiency rickets, and spastic ataxia of Charlevoix-Saguenay, respectively) reveal the interpopulation and intrapopulation genetic diversity of Quebec. Inbreeding does not explain the clustering and prevalence of these genetic diseases; genealogical reconstructions buttressed by molecular evidence point to founder effects and genetic drift in multiple instances. Genealogical estimates of historical meioses and analysis of linkage disequilibrium show that sectors of this young population are suitable for linkage disequilibrium mapping of rare alleles. How the population benefits from what is being learned about its structure and how its uniqueness could facilitate construction of a genomic map of linkage disequilibrium are discussed

  15. The gasoline retail market in Quebec

    International Nuclear Information System (INIS)

    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

    We conducted a preliminary evaluation of a lake whitefish (Coregonus clupeaformis) bioenergetics model by applying the model to size-at-age data for lake whitefish from northern Lake Michigan. We then compared estimates of gross growth efficiency (GGE) from our bioenergetis model with previously published estimates of GGE for bloater (C. hoyi) in Lake Michigan and for lake whitefish in Quebec. According to our model, the GGE of Lake Michigan lake whitefish decreased from 0.075 to 0.02 as age increased from 2 to 5 years. In contrast, the GGE of lake whitefish in Quebec inland waters decreased from 0.12 to 0.05 for the same ages. When our swimming-speed submodel was replaced with a submodel that had been used for lake trout (Salvelinus namaycush) in Lake Michigan and an observed predator energy density for Lake Michigan lake whitefish was employed, our model predicted that the GGE of Lake Michigan lake whitefish decreased from 0.12 to 0.04 as age increased from 2 to 5 years.

  17. Hydro-Quebec : annual report 1998 : for today and tomorrow

    International Nuclear Information System (INIS)

    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

  18. Using energy to build the Quebec of tomorrow : Quebec energy strategy 2006-2015 : summary

    International Nuclear Information System (INIS)

    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.

From his personal experience, the author discusses. The evolution of the Départment de psychiatric de l'Université de Montréal fro where were issued more than 1000 psychiatrists who shaped clinical practice and research developments worthy of mention throughout the years. The evolution of diagnostic noselogy from the DSM-ii, very influenced by psychoanalysis, to the DSM-5 that is more atheortical, but that is still not based on objective data, which remains a challenge to the etiology of mental illness. The psychiatric drugs that we have learned to prescribe in the past 50 years in a more rational way thanks to a better understanding of their action mechanisms. In reality, there has been no discovery of new drug categories; rather it is the way we prescribe medication that evolved.

  3. The development of the wind power industry in Quebec

    International Nuclear Information System (INIS)

    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

  4. Ambient air quality in Lower Town Quebec

    International Nuclear Information System (INIS)

    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 (CO2) and sulphur dioxide (SO2), 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

  5. Hydro-Quebec and energy efficiency

    International Nuclear Information System (INIS)

    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

    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

  7. Hydro-Quebec strategic plan 2006-2010

    International Nuclear Information System (INIS)

    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

  8. Perceptions of the Quebec population regarding the development of the electric power industry in Quebec

    International Nuclear Information System (INIS)

    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

  9. Hydro-Quebec MED (Diametric Expansion Measurement)

    International Nuclear Information System (INIS)

    This paper describes a method for measuring the diametral expansion of the pressure tubes at Gentilly-2 nuclear generating station. The aim is to describe the solutions, the calibration tools, and the analytical methods developed for the project. To measure the diametral expansion of the pressure tubes, Hydro-Quebec modified the SLARette device and integrated a new module called MED. The measurement system is made up of three parts: 1. An inspection head, the MED (Hydro-Quebec) module, which has five ultrasonic probes that determine the distance between the inspections head and pressure tube. Measurements are always done under water and they are used to determine the diameter and thickness of the pressure tubes. 2. Tomoscan III acquisition system by R/D Tech to scan the five probes and save the data in an A-scan file. 3. An Analytical software: LogaMED (Hydro-Quebec). The advanced delivery machine (ADM) equipped with a SLARette device is primarily an axial inspection system. The ADM and SLARette device are not capable of performing an axial/rotational inspection and have no centering system. However, measuring the diametral creep requires spiral scanning and a centered tool. A method that would allow the walls of the tubes to be measured in an uncentered way and to recalculate the diameters as if the device were centered has been designed. An automatic analytical software program (LogaMED) was designed to perform the calculation. LogaMED reads A-scan file data and provides the user with information on diameter and thickness. Two methods can be used to determine the diameter. The first consists in moving lengthwise through the tube. Several passes can be done at different angles and the results compiled in LogaMED. The second method is used to measure the diameter at every angle with an angular displacement (3600 rotation). Two of the main problems that had to be resolved were the calibration of the calculation parameters and the determination of measurement

  14. Contribution to Quebec's economic development: Development plan 1993

    International Nuclear Information System (INIS)

    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

  15. Hydro-Quebec International : taking up the challenges of globalization

    International Nuclear Information System (INIS)

    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

    Energy Technology Data Exchange (ETDEWEB)

    1994-06-01

    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.

  17. Earthquake-induced liquefaction in Ferland, Quebec

    International Nuclear Information System (INIS)

    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

  18. Mercury contamination in northern Quebec: State of the situation and role of the James Bay Mercury Committee

    International Nuclear Information System (INIS)

    The James Bay Mercury Committee has the responsibility of implementing the Convention on Mercury adopted by the Quebec Government, Hydro-Quebec, and the Cree people living in the area near James Bay affected by mercury contamination in Hydro-Quebec reservoirs. The Convention program includes activities which are reviewed in the areas of environmental research and monitoring, impact studies, and development of remedial measures. Environmental monitoring results obtained in 1992 show that in the LG-2 reservoir, mercury levels in most of the fish species captured remain higher than in the natural environment. Downstream from the LG-2 dam, lake whitefish and longnose sucker have higher mercury levels than those in the LG-2 reservoir. In more recently constructed reservoirs, such as Caniapiscau, mercury levels have stabilized in non-piscivorous fish but continue to rise in the northern pike. Environmental research conducted includes an experimental study of methylation in the Experimental Lakes Area (Ontario), an evaluation of health indicators of methylmercury exposure in mink, improvement of analytical methods, and modelling of mercury flux in reservoirs. In recent studies of mercury exposure among the Cree, mercury concentrations in hair have stabilized to levels having no risk for most people. The first phase of an epidemiological study of mercury toxicity among the Cree has been completed, indicating that a reference population of sufficient size exists at Chisasibi and Wemindji to determine the health consequences, if any, of long-term mercury exposure. A socioeconomic survey of Cree affected by mercury contamination was also conducted, and a mitigation program was established for communities affected by the LaGrade complex. 13 refs., 3 figs

    A multi-disciplinary approach was used to evaluate the health of yellow perch (Perca flavescens) in the St. Lawrence River (Quebec, Canada), which is experiencing a severe population decline in the downstream portion of the river. Physiological parameters, liver alterations, trace metal concentrations, parasite prevalence and abundance, stable isotope composition, and the presence/absence of the viral hemorragic septicemia virus (VHSV) were evaluated in perch collected at six sites along the river: Lake St. François, Lake St. Louis (north and south), Beauregard Island, and Lake St. Pierre (north and south). Trace metal concentrations in surface water were higher in Lake St. Louis and downstream of a major urban wastewater treatment plant discharge, indicating that this effluent was a significant source of Cu, As, Ag, Zn, and Cd. Levels of Pb in surface water exceeded thresholds for the protection of aquatic life in Lake St. Louis and were negatively correlated with body condition index in this lake. In Lake St. Pierre, Cu, Ag, and Cd bioaccumulated significantly in perch liver and lower body condition index and greater liver damage were observed compared to upstream sites. Parasite analyses indicated a higher abundance of metacercariae of the trematodes Apophallus brevis and Diplostomum spp. in Lake St. Louis, and VHSV was not detected in the liver of yellow perch for all studied sites. Overall, results suggested that the global health of yellow perch from Lake St. Pierre is lower compared to upstream studied sites, which could contribute to the documented population collapse at this site.

    Full Text Available Fertilizer recommendations for cranberry crops are guided by plant and soil tests. However, critical tissue concentration ranges used for diagnostic purposes are inherently biased by nutrient interactions and physiological age. Compositional data analysis using isometric log ratios (ilr of nutrients as well as time detrending can avoid numerical biases. The objective was to derive unbiased nutrient signature standards for cranberry in Quebec and compare those standards to literature data. Field trials were conducted during 3 consecutive years with varying P treatments at six commercial sites in Quebec. Leaf tissues were analyzed for N, P, K, Ca, Mg, B, Cu, Zn, Mn and Fe. The analytical results were transformed into ilr nutrient balances of parts and groups of parts. High-yield reference ilr values were computed for cranberry yielding greater than 35 Mg ha-1. Many cranberry fields appeared to be over-supplied with K and either under-supplied with Mn or over-supplied with Fe as shown by their imbalanced [K | Ca, Mg] and [Mn | Fe] ratios. Nutrient concentration ranges from Maine and Wisconsin, USA, were combined into ilr values to generate ranges of balances. It was found that these nutrient ranges were much too broad for application in Quebec or outside the Quebec ranges for the [Ca | Mg] and the [Mn | Fe] balances, that were lower compared to those of high yielding cranberry crops in Quebec.

    1996-01-01

    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.

    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.

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

    International Nuclear Information System (INIS)

    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

  9. Evidence of late glacial paleoseismicity from submarine landslide deposits within Lac Dasserat, northwestern Quebec, Canada

    Science.gov (United States)

    Brooks, Gregory R.

    2016-09-01

    An integrated seismo- and chronostratigraphic investigation at Lac Dasserat, northwestern Quebec, identified 74 separate failures within eight event horizons. Horizons E and B, and H and G have strong or moderately-strong multi-landslide signatures, respectively, composed of 11-23 failures, while horizons F, D, C, and A have minor landslide signatures consisting of a single or pair of deposit(s). Cores collected at six sites recovered glacial Lake Ojibway varve deposits that are interbedded with the event horizons. The correlation of the varves to the regional Timiskaming varve series allowed varve ages or ranges of varve ages to be determined for the event horizons. Horizons H, G, E, and B are interpreted to be evidence of paleoearthquakes with differing levels of interpretative confidence, based on the relative strength of the multi-landslide signatures, the correlation to other disturbed deposits of similar age in the region, and the lack or possibility of alternative aseismic mechanisms. The four interpreted paleoearthquakes occurred between 9770 ± 200 and 8470 ± 200 cal yr BP, when glacial Lake Ojibway was impounded behind the Laurentide Ice Sheet during deglaciation. They probably represent an elevated period of seismicity at deglaciation that was driven by crustal unloading.

  10. Assessing the cause of impacts on benthic organisms near Rouyn-Noranda, Quebec

    2004-05-01

    Sediments from lakes near Rouyn-Noranda, Quebec, contain elevated concentrations of several metals, including Cd, Cu, Pb and Zn. Amphipods, fingernail clams, mayflies and tanytarsid midges were absent, and sediment toxicity was observed in chronic tests with Hyalella in sediments from Lac Dufault, the lake closest to Rouyn-Noranda. Bioaccumulation by Hyalella demonstrated elevated bioavailability of Cd, Co, Cr, Pb and Tl, but only Cd was accumulated to levels close to the toxic threshold. Copper, which is regulated by Hyalella, was not elevated in these amphipods, but it was elevated in overlying water in the toxicity tests. Toxic effects in Lac Dufault sediments are probably caused primarily by Cd, at least in amphipods, with a possible minor contribution from Cu. An integrated assessment, including sediment chemistry, benthic community composition, sediment toxicity, metal bioaccumulation in benthos, and comparison of bioaccumulation and/or overlying water concentrations with threshold effect concentrations, provides the best indication of effects and their cause. - Metal bioaccumulation and metals in overlying water during toxicity tests help identify the cause of sediment toxicity and reduced benthic biodiversity.

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

    International Nuclear Information System (INIS)

    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

  19. Sweeping changes at Hydro-Quebec : the new electricity market

    Energy Technology Data Exchange (ETDEWEB)

    Carpentier, J-M.

    2001-10-01

    Recent changes in the organization and policies of Hydro-Quebec, which could place the utility giant in front and centre of a possible North American energy common market, are discussed. In this context, the discussion covers the development of the La Grange hydroelectric development in the 1970s and 1980s, the subsequent signing of long-term export contracts with large power grids in the United States, and the more recent developments in opening up of electricity markets. Some implications of these changes, such as the marketing of electricity on electronic stock exchanges at prices that move in step with supply and demand (spot pricing), the establishment of separate generating, transmission and distribution divisions, and the introduction of new operating procedures designed to satisfy the new rules of reciprocity between liberalized electricity markets, are also described. As part of this new set of marketing tools Hydro-Quebec is planning to construct a $185-million power line between Connecticut and Long Island through its subsidiary, TransEnergy US, to boost transmission capacity, which will be allocated by secondary transmission rights. These rights can be sold and traded in financial markets, the first such undertaking in the United States. Unlimited access to US markets for Hydro-Quebec will be also facilitated by Bill 116, enacted by the Quebec Legislature in June 2000, which will give US utilities access to the Quebec wholesale market. These, and other changes of similar magnitude will radically change the energy supply landscape and open up the electricity market in the province to the outside world more than ever in the past. 5 photos.

  20. The implications of the nuclear option in Quebec

    International Nuclear Information System (INIS)

    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)

  5. Defense plan of Hydro-Quebec for extreme contingencies

    International Nuclear Information System (INIS)

    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

    An historical overview of the James Bay Hydroelectric Power Development in northern Quebec was provided. The account touches upon the foundation of the Societe d`energie de la Baie James, a wholly-owned subsidiary of Hydro-Quebec. It describes the La Grande Complex, and provides a brief summary of the site investigation, the geological and geotechnical considerations, the rock excavation, the construction of embankments and dikes, and nature of the bedrock and overburden foundations. Some of the more interesting problems that arose during the construction such as the settling of the crest in the protective islands surrounding the instruments at some of the dam sites were outlined. Leakage under some of the La Grande 3 low head dikes near the end of the reservoir filling period and the degradation of some of the riprap protection of the Phase One embankments were also described. The solutions designed to overcome these problems were also part of the account of this major mega development project that promoted Quebec into the ranks of the major hydro energy producers in North America. 11 refs., 2 tabs., 3 figs., photos.

  7. The petrochemical industry in Quebec : from yesterday to today

    International Nuclear Information System (INIS)

    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

    The main objectives of this study were to assess the production potential of forest biomass in Quebec; determine the current use of this potential; estimate surplus biomass by source and by product category; forecast the use of surplus biomass over the next decade, quantify the practical availability during the same period; examine possible conflicts between current and new uses of biomass; suggest, if necessary, means of reducing these conflicts; and make general recommendations with regard to the use of surplus forest biomass over the next ten years. Since Quebec forests cover a vast area, the territory was divided into 26 separate study units. The total above-ground wood biomass available annually, in Quebec's forests, is 35 million m/sup 3/ or 15 million oven-dry metric tonnes under extensive management. Logging residues represent 10% of this quantity, merchantable full trees 60%, and unmerchantible trees 30%. The energy equivalent of this biomass represents annually 3.6 billion litres of oil. 7 figs., 20 tabs.

  9. 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.

  10. The role of governments in the Quebec energy market: Opening of the export market in Quebec's electricity: Reality or a mirage on the horizon?

    International Nuclear Information System (INIS)

    One of the principal goals of Hydro-Quebec is to be recognized as a world-class utility that produces and distributes electricity in Quebec, North America and in the international market. A review of electricity export by Hydro-Quebec and the impact of FERC order 888 was presented. Opening the electricity market in North America has meant that consumers now have a greater choice of power producers. With electricity prices being set by the market, Hydro-Quebec expects to have a price advantage over their competitors. In 1996, 7.8 per cent of Hydro-Quebec electricity was exported to Ontario, New Brunswick, New York, and the new England States. According to Hydro-Quebec's strategic plan for 1998-2002 opportunities exist to expand the volume of export to the American market, and with it realize sizable increases in profits. Two factors that might limit the profitability of exporting electricity to this market, namely institutional barriers forcing lower tariffs based on average transportation costs, and the peculiarity of Quebec's practice of tariffs favoring the domestic market more than the export market, have been highlighted. 15 refs., 2 tabs

  15. Hydro-Quebec 2004 annual report : growing strong

    International Nuclear Information System (INIS)

    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

    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.

    Control of vegetation is required as part of adequate dam structure inspection in order to prevent initiation of failure mechanisms. This paper presented an overview of the issues related to plant material on Hydro-Quebec embankment dams. The Dam Safety Act, the Hydro-Quebec safety program, legal requirements, including MDDEP authorisation certificates, and professional requirements are presented to provide an overview of some of the regulatory issues related to plant material on dams in Quebec. Hydro-Quebec described its integrated plant material management program and investigated the techniques used for vegetation control in its five production territories over the last decade. Recent concerns that have emerged over aspects such as worker safety are also developed. This paper showed that it is not necessary to remove all traces of vegetation on embankment dams. It was also found that the current Hydro-Quebec internal regulation SB-70-01-00 needs to be changed.

    Objective: The Substance Use Risk Profile Scale (SURPS) has been developed to screen personality risk factors for substance misuse. This scale assesses 4 high-risk personality traits using a 23-item, self-report questionnaire. SURPS helps guiding targeted approaches to prevention of substance abuse and misuse. It has been validated in the United Kingdom, English Canada, Sri Lanka, and China. This study aims to validate this scale in a sample of French-speaking adolescents from Quebec as well as its sensitivity in a clinical sample of adolescents. Method: Two hundred two 15-year-old youths from a community sample completed a French version of SURPS as well as other measures of personality and substance use. This study reports the internal consistency and concurrent validity of the scale, as well as a factor analysis of items. Further, 40 youths (mean age 15.7 years) from a clinical population completed SURPS and their scores were compared with those of the community sample. Results: SURPS French translation has good internal consistency and demonstrated a 4-factor structure very similar to the original scale. The 4 subscales show good concurrent validity, and 3 of the subscales were found to correlate with measures of substance use. Finally, 95% of the clinical sample was identified at high risk for substance misuse according to SURPS cut-off scores. Conclusion: SURPS French translation seems to be a valid and sensitive scale that can be used in a French-speaking adolescent population from Quebec.

    Awareness of groundwater protection has increased substantially in recent decades. In the Province of Quebec, Canada, the Groundwater Catchment Regulation (GWCR) was promulgated in 2002 to protect water quality in public wells. The goal of the present study was to document groundwater protection in the context of emerging regulations and identify factors explaining the propensity of municipalities applying protection strategies. Two types of information were used in this study: data from a questionnaire-based survey conducted among 665 municipalities in the Province of Quebec and complementary information gathered from various sources. Data from the survey revealed that fewer than half of the municipalities have been able to comply with the GWCR, mainly because of financial limitations. Also, close to half of the municipalities have either identified or are expecting land use conflicts to arise between protection areas required by the GWCR and other land usage, with agriculture being the main conflicting activity. Multivariate logistic regression models served to identify factors explaining the likelihood of municipalities to take groundwater protection measures. Those factors were municipality revenue, history of water contamination in distribution systems, land use near wellheads, location of municipalities within a provincial priority watershed and the importance of groundwater use in a region. Results of the study may prove helpful for government authorities in better understanding the groundwater protection issue and in implementing strategies that improve the ability of municipalities to protect groundwater.

  3. Quebec mental health services networks: models and implementation

    2005-06-01

    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.

    1983-10-01

    In the late 1960s, Quebec demonstrated its willingness to influence migration by creating a Ministry of Immigration. The goal of the Ministry changed over the course of a decade from assuring harmonious integration of immigrants to obtaining a greater role in recruitment and selection as well as in reception and establishment. In the early 1970s the Canadian government undertook a significant revision of its immigration policies. The most significant change was probably the requirement of an annual estimate of the number of immigrants judged opportune to admit during a particular time period. to be preceded by consultations with the provinces concerning demographic needs and the labor market. A 1978 agreement between Quebec and the Canadian government gave Quebec a greater role in immigrant selection and recruitment, and in effect allowed it to develop its own immigration policy. Ability to absorb potential immigrants became the primary criterion in setting quotas for Quebec. The approach of the federal government has not changed greatly since the new policy came into use. The extent of annual net immigration judged desirable has changed from about 75,000 persons initially to about 55,000 more recently. The federal government has always viewed immigration as a possible solution to labor market problems, but estimates of manpower needs became very volatile in the late 1970s with the general rise in rates of unemployment, and survey results lost importance as a source of guidance. The government estimated that 20 to 25 thousand immigrants selected to fill specific manpower needs could be accomodated annually in the 1980s, but the collapse of the labor market following the economic crisis caused a downward revision in estimates for 1982-83 to 8000 to 10,000 workers with jobs already in hand. In order to participate in planning of immigration, Quebec had to develop a research program desinged to identify its capacity to absorb immigrants each year. The 1st step was to

    Data on anaphylaxis cases in pre-hospital settings is limited. As part of the Cross Canada Anaphylaxis Registry (C-CARE), we assessed anaphylaxis cases managed by paramedics in Outaouais, Quebec. A software program was developed to prospectively record demographic and clinical characteristics as well as management of cases meeting the definition of the anaphylaxis. Univariate and multivariate logistic regressions were compared to assess factors associated with severity of reactions and epinephrine use. Among 33,788 ambulance calls of which 23,486 required transport, 104 anaphylaxis cases were identified (anaphylaxis rate of 0.31% [95%CI, 0.25%, 0.37%] among all ambulance calls and 0.44% [95%CI, 0.36%, 0.54%] among those requiring transport). The median age was 46.8 years and 41.3% were males. The common triggers included food (32.7% [95%CI, 24.0%, 42.7%]), drugs (24.0% [16.4%, 33.6%]), and venom (17.3% [10.8%, 26.2%]). Among all reactions, 37.5% (95%CI, 28.4%, 47.6%) were severe. Epinephrine was not administered in 35.6% (95%CI, 26.6%, 45.6%) of all cases. Males were more likely to have severe reactions (Odds ratio [OR]: 2.50 [95%CI, 1.03, 6.01]). Venom-induced reactions and severe anaphylaxis were more likely to be managed with epinephrine (OR: 6.9 [95%CI, 1.3, 35.3] and 4.2 [95%CI, 1.5, 12.0], respectively). This is the first prospective study evaluating anaphylaxis managed by paramedics. Anaphylaxis accounts for a substantial proportion of the cases managed by paramedics in Outaouais, Quebec and exceeds prior reports of the proportion of Quebec emergency room visits attributed to anaphylaxis. Although guidelines recommend prompt use of epinephrine for all cases of anaphylaxis, more than a third of cases did not receive epinephrine. It is crucial to develop educational programs targeting paramedics to promote the use of epinephrine in all cases of anaphylaxis regardless of the specific trigger. PMID:26734462

    This paper analyzes the debates surrounding the privatization of health services financing in Quebec. The objective is to clarify policy-making processes with regard to this important issue and, more generally, to provide a realistic understanding of health-related policy processes in Canada. The analysis is based on a large and continuous sample of mass media and National Assembly debates on the question during the four-and-a-half years following the Chaoulli ruling of the Supreme Court of Canada. These data are used to test four hypotheses about relationships among the types of political actors involved, their policy preferences, the rhetoric they use and the anticipated policy effects they assert. The results are applied to a discussion of questions about the factors that influence the effectiveness of political communication. PMID:23968604

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

    International Nuclear Information System (INIS)

    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

  10. Primary reasons for osteopathic consultation: a prospective survey in Quebec.

    Directory of Open Access Journals (Sweden)

    Chantal Morin

    Full Text Available BACKGROUND: Osteopathy is an increasingly popular health care modality to address pain and function in the musculoskeletal system, organs and the head region, as well as functional somatic syndromes. Although osteopathy is recommended principally in guidelines for management of back pain, osteopaths' scope of practice is wide, albeit poorly defined. In order to understand better the practice of osteopathy, this study aimed to investigate the most common reasons for osteopathic consultations in clinical settings in Quebec. METHODS: A prospective survey of members of the Registre des ostéopathes du Québec was conducted to examine demographics in osteopathic practices, as well as patients' primary reasons for consultations over a two-week period. The questionnaire was devised following a literature review and refined and verified with two stages of expert input. RESULTS: 277 osteopaths (60[corrected]% response rate responded to the survey notice. 14,002 patients' primary reasons for consultations were reported in completed questionnaires and returned by practicing osteopaths. Musculoskeletal pain located in the spine, thorax, pelvis and limbs was the most common reason for consultations (61.9%, with females consulting most commonly for cervical pain and males for lumbar pain. Perinatal and paediatric (11.8%, head (9.1%, visceral (5.0% and general concerns (4.8% were the other most common reasons for consultations. Preventive care represented the remaining 0.3%. INTERPRETATION: The nature of primary reasons for osteopathic consultations, coupled with documented satisfaction of patients with this approach, suggest a future for multidisciplinary collaborative health care including osteopathy. Results of this survey may contribute to informing physicians and others pending regulation of Quebec osteopaths, and also provide direction for future clinical research and guidelines development.

  12. Quebec's Medical Aid in Dying: An Inspiration for Other Canadian Jurisdictions?

    Science.gov (United States)

    2016-02-01

    Soon, physicians across Canada will be permitted to assist patients in dying, provided certain conditions are met. Physicians in the province of Quebec can already provide this service since December 10, 2015. While Quebec has been studying the question of legislating medical aid in dying since 2009, the rest of the country must come up with legislation on this issue within the next few months. This article suggests that other Canadian jurisdictions, federally and provincially/territorially, may find inspiration in the extensive work done in Quebec leading to its end-of-life legislation, including on the issues of identifying proper safeguards to protect vulnerable people and eligibility criteria that could be put in place in these jurisdictions. The Quebec model could be particularly useful in regard to the approach to balancing physicians' rights of conscience with patients' constitutional right to access medical aid in dying.

    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.

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. The emergence of the notion of 'cultural communities' as a result of the constitutional rivalry and the on-going struggle for legitimacy between Quebec and Ottawa is also explored."

    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

    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

  20. Evaluating the SWAT's snow hydrology over a Northern Quebec watershed

    The snowmelt is an important component of the Soil Water Assessment Tool (SWAT[1]) model's hydrology when applied in snowy watersheds where spring flows are dominated by snow melting. However, little is known about its performance in modeling Nordic environments and its accuracy with respect to operational snowmelt models because most studies were conducted in rainfall-runoff catchments. To fill this gap in SWAT's knowledge, we aim to evaluate its performance for simulating a snowy Nordic catchment streamflow with comparison to the Streamflow Synthesis and Reservoir Regulation (SSARR[2]) model. SSARR is one of the selected operational models by the Snow Hydrology Guide as valuable tool for snowmelt runoff simulation (Ontario Ministry of Natural Resources, 1989). In the Côte Nord region of Quebec, most of the streamflow come from snowmelt in watersheds. Understanding the interactions among snow accumulation, snowmelt and streamflow generation is a challenge for water resources management in Quebec, since this province is the Canada's leader in hydroelectric energy production. The selected snow-covered watershed, namely the Outardes Basin, presents extreme climatic conditions. Few examples of model calibration in this Nordic environment exist because of the scarcity of reliable data. The basin has the interest of being well instrumented providing a comprehensive dataset to implement SWAT over this Nordic watershed. The evaluation indicates that SWAT has a good performance in simulating the daily, monthly, seasonal and annual mean discharges with low volume biases over the calibration and validation periods. The predominantly spring snow-melting generated streamflow is simulated with a good accuracy for both its magnitude and its timing. Seasonal snowpack plays an important role in defining the hydrologic regime where the accumulated snowmelt runoff contributes to 64% of the annual runoff. When we compared SWAT's results to SSARR, comparable performances in

  3. Hydro-Quebec inspection robot RIT-LRG

    International Nuclear Information System (INIS)

    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)

    The (87)Sr/(86)Sr isotope ratios were measured on grape, wine and soil samples collected in 13 commercial vineyards located in three major wine producing areas of Quebec (Canada). The soils yield Sr isotope ratios that are intimately related to the local geology and unambiguously discriminate the different producing areas. A strong relationship exists between the (87)Sr/(86)Sr isotope ratios of the wine and the grapes. This suggests that the vinification process does not alter the overall Sr budget. Although the Sr isotope ratios of the grapes do not show a strong correlation with the bulk Sr isotope composition of the soil, they do correlate strongly with the Sr isotope composition contained in the labile fraction of the soil. This indicates that the labile fraction of the soil represents the Sr reservoir available to the plant during its growth. This study demonstrates that the Sr isotope approach can be used as a viable tool in forensic science for investigating the provenance of commercial wines.

  6. Opening new horizons, building new synergies : 1998 annual report of Hydro-Quebec International

    International Nuclear Information System (INIS)

    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

    2009-05-01

    A significant percentage of the northern Quebec boreal region consists of minerotrophic peatland. Their impact on large-scale watersheds, used for hydroelectric production, is important, especially in relation to climate change. During the last decades, a subtle increase in the surface of ponds at the expense of terrestrial compartments has been observed. To better understand the impacts of this development, a multidisciplinary study to perform a complete integrated analysis of the water balance was launched in summer 2008 on the Abeille peatland (54° 06'52" N, 72° 30'01"W), a minerotrophic peatland with an open-water surface. While all features of the water balance will be considered (precipitation, evapotranspiration, runoff, storage and error), some will be studied in greater depth. Notably, evapotranspiration and storage changes will be considered, since, they are particularly difficult to measure in peatland ecosystems. Indirect methods for estimating actual evapotranspiration are often used. One method is to use a semi-empirical formula to estimate potential evapotranspiration. The main problem with this method is that a relationship between potential and actual evapotranspiration must be established and this is a highly variable process for peat ecosystems. To establish a relationship appropriate to our study site, different methods of direct measurement of the actual evapotranspiration will be used (lysimeters, turbulence flow, daily fluctuations of storage, etc.) and compared. A dense network of wells has been installed to enable monitoring of changes in storage and subsurface runoff. A high accuracy topographic survey will be executed to assess the total water content of the site. A device for measuring the variation of peat surface elevation will also be established. Preliminary results are showing complex dynamic behaviors of water migration through the site, therefore opening the way to new questions and hypotheses to clarify in the coming years.

  11. Hydro-Quebec: research and development highlights 1998

    International Nuclear Information System (INIS)

    1998 confirmed once again that any planning in R and D must take into consideration unforeseen events. Actions are measured against their profitability, and R and D must contribute to increasing a company's competitive edge by providing it with new sources of revenue, by ensuring that it benefits from real savings and coming up with the best possible solutions to its technological problems. Hydro-Quebec's results attest to the fact that R and D is an investment that contributes to the utility's profitability. Whether trying to reduce maintenance costs through robot systems or cameras, improving injection methods for repairing dams, developing monitoring systems or new devices aimed at increasing the availability of equipment or reducing the environmental impact of its installations, the company's R and D projects have helped maintain its position as a world leader in the generation and transmission of hydroelectric power. The company is counting on technological innovation to boost the revenues of th e utility's business units. Examples include the work done to optimize the management of energy reserves, increase the network's load-flow capacity and flexibility, generate an electrical supply that meets international standards, and offer alternative distribution system solutions. Other projects involve improving turbine efficiency by modelling fluid flow, devising methods for forecasting natural inflows, analyzing losses in saturation transformers, developing the intelligent power system, and studying transient stability in real time, load frequency control, and customized power quality. Further projects are aimed at developing technologies and services that increase client loyalty and expand the client base such as research into energy management for low income clients, use of geothermal energy, new applications for electrotechnologies, electromagnetic compatibility, drive power and applications of lignin

    Full Text Available The Canadian health care system – known as “Medicare” or “Assurance-maladie” in Quebec – was created to ensure Canadians free access to health care services and medications. The health system is both publicly funded and administered. It has been built on five principles laid out in the Canada Health Act (1984; these are: Public Administration, Comprehensiveness, Universality, Portability, and Accessibility. In sum, the right to health has been at the organizational core of the Canadian health system. Provinces and territories administer and deliver most of the health services in Canada. This is done through provincial and territorial health insurance plans which are required to follow the national principles set out in the Canada Health Act. Since its creation, the Canadian health care system has undergone important changes and reforms. However, until a few years ago each major reform of the system retained the principles of justice and equity as core values. Quebec adopted the Health and Social Services Act in December 1971. The Quebec health care system was established with a mandate to maintain, improve, and restore the health and well-being of the entire Quebec population, making health and social services accessible to all. Health and social services in Quebec are administered jointly. This specificity, which has been adopted by other health care systems, has the advantage of allowing a comprehensive response to the health and social needs of the population. Since the 80s there has been a worldwide trend towards the privatization of public services. In order to describe developments in the Quebec health care system, we interviewed Dr Marie-Claude Goulet (M-CG, chair of the organization Médecins québécois pour le régime public (MQRP [Quebec Physicians for a Public System] , an organization campaigning against the commercialization of health care in Quebec.

    Full Text Available The Quebec Social Forum (QSF took place 23-26 August 2007 in Montreal. It attracted about 5000 people from across Quebec. Both organizers and observers viewed the event as an unqualified success. In this article, we seek to describe and document this historic gathering and to understand it in its Quebec context, against the larger organizing process which produced it. We also situate the Social Forum, both as event and process, within the longer history of social mobilization in Quebec. Historicizing the Social Forum in this way helps us interpret its cleavages and conflicts more adequately and apprehend its larger significance. We argue that the conflicts that have plagued the organizing of the Quebec Social Forum are a reprise of those that appeared in the movement in the late 1990s and came to a head in the 2001 massive demonstrations against the Free Trade Agreement of the Americas in Quebec City. The chasm then was widely perceived as one over tactics but we argue, then and now, it is more substantive than that. It is about the clash of profoundly different ethics, practices and theories of democracy and, beneath them, different horizons of hope and visions of transformation. The organizing of the Social Forum is the occasion for this debate, which may say something about the significance of the Social Forum more generally and the challenge it poses to established cultures and practices of politics on the left. The cleavage is generational but not only or simply. It signals a struggle and transition but the outcomes are not yet clear and are certainly not pre-ordained.

However, husbands and wives of centenarians lived 4 and 2.5 years longer than theircounterparts of the same sex, respectively, suggesting that longevity is also modulated by shared environment in adulthood.

  1. Black carbon characterization in Quebec black spruce forests

    2014-05-01

    Black carbon (BC), an important component of the global soil carbon pool, is a major by-product of wildfires in Quebec black spruce forests. However, BC characteristics vary depending on the environmental conditions under which it is formed and this may further affect its resistance to degradation. The objective of this study was to characterize the chemical and physical properties of BC formed under variable fire severity to assess its potential for recalcitrance as a passive carbon pool. Samples (n = 267) of BC produced by early season wildfires in 2005-2007 were collected from the surface of black spruce forest floors to cover the range of severity encountered in these fire-affected forests. Representative samples (n = 33) were then analyzed using elemental analysis, solid-state 13C nuclear magnetic resonance (NMR) spectroscopy, scanning electron microscopy and surface area analysis (BET method). Properties of BC sampled in the field were compared with those of samples produced under a range of controlled formation conditions in the laboratory. The NMR spectra of the BC collected on sites affected by low fire severity showed a distribution of total intensity between the different spectral regions very similar to those of unburned fuels, and were dominated by peaks indicative of cellulose, while spectra for BC from higher fire severity sites were dominated by a broad peak assigned to aromatic carbons. Atomic H/C and O/C ratios decreased along the fire severity gradient, confirming that increasing severity was associated with an increase in condensation. By comparing field- to laboratory-produced samples, we concluded that the temperature of formation in the field ranged between 75 and 250 ° C. In all analyzed BC samples, the fraction of aromatic carbon:total carbon was low, suggesting that the freshly produced BC in this boreal forest environment may be susceptible to rapid physical alteration and chemical degradation. Nevertheless, it is important to highlight

    2006-01-01

    While Canada's international leadership in the area of health promotion has been widely acknowledged in the past, Quebec's approach could be better known. Canada's second largest province has indeed developed a comprehensive public health infrastructure and adopted a population health approach which features an integrated set of legislative, organizational and programmatic policy instruments. These instruments not only ensure the core functions of public health, but also foster public intervention on the social determinants of health. In addition, Quebec's policy is supported by a solid research infrastructure, networked expertise and a mobilized workforce among health professionals. In spite of the interest it represents for the larger public health community in Canada and elsewhere, this largely French-speaking province's approach remains little known because of language and cultural barriers between Quebec and Anglo-Saxon countries, and it has yet to be systematically discussed in the English-language literature. This article provides an overview of policies and administrative structures in Quebec to support public health and address socially determined inequalities in health. It analyzes the development of these policies over the past decade and offers insight to their core content. PMID:16681186

  19. Snowpack and snowmelt modeling of a subarctic catchment in northern Quebec, Canada, using an energy and mass balance approach

    Oreiller, M.; Rousseau, A. N.; Minville, M.

    2012-12-01

    There is a growing interest in modeling snowpack evolution and spring runoff in northern Quebec, Canada, where there are several large-scale hydropower complexes. This region (49th to 55th degree north), characterized by boreal forest, lakes and wetlands, is highly remote and snowpack observations are very sparse. The objective of this study is to improve the snow module of HYDROTEL, a distributed continuous hydrological model currently used to predict inflows to large hydropower reservoirs of the region, with the help of continuous in-situ measurements of snow water equivalent. Up to now HYDROTEL has relied on a mixed degree-day/energy balance method to simulate accumulation and depletion of the snow cover. This approach has the advantage of requiring a small number of input data, but under changing climate conditions such as those recently experienced unusually high temperature in late winter or rain-on-snow events it has a tendency to generate unreliable results. We thus implemented a completely physically-based snow module, CROCUS, and try to determine whether HYDROTEL could benefit from an energy and mass balance approach. CROCUS, originally developed for snowpack simulations in the French Alps, has been adapted to the specific environmental characteristics of the boreal region. The simulation can now be validated with snow water equivalent collected by a GMON sensor, which evaluates absorption of the natural ground gamma radiation by the snowpack. The number of input data required by CROCUS is more important (seven meteorological variables on an hourly basis instead of two on a daily basis for the current version of HYDROTEL's snow module) which makes it more complex to use and at this points too complex to be implemented directly as a subroutine in HYDROTEL. However, this study shows that HYDROTEL is much more effective at predicting winter and spring runoff when using CROCUS as the snow module.

    The Coop Federee addresses all agricultural issues facing rural Quebec. It represents more than 51,000 members from 101 agricultural co-operatives that address a variety of needs on behalf of agricultural producers and consumers. As a wholesaler, the Coop Federee provides goods and services, including petroleum products, to its members in Quebec, Ontario and New Brunswick. This document addressed issues related with the recent announcement by the Quebec Government that Hydro-Quebec would launch a second invitation to bid on 2000 MW wind power. With the first invitation to bid on 1000 MW launched in 2003, the premier of Quebec affirmed to make Quebec a world leader in the field of green energy. The Government of Quebec requires that 60 per cent of the components in the wind park must come from within Quebec. Therefore, if a 100 MW wind park involves an investment of $170 million, then $102 million dollars will undoubtedly be spent in the province, plus any added expenditures such as maintenance, labour and taxes. Over the 20 year lifespan of the project, this represents approximately $3.5 billion dollars from a 2000 MW wind project. This represents a significant contribution to the province's economic development. This paper presented a critical examination of the proposal, with reference to external promoters of wind power. It also addressed the issue of potential negative consequences which may, in the long-term, present a barrier to the development of wind power in the province. 9 refs., 2 tabs., 2 appendices.

    Full Text Available Abstract Objective To determine the population incidence of juvenile rheumatoid arthritis (JRA in Quebec. Methods We obtained data from Quebec's physician claims database. Incident cases were defined as having a visit for JRA in 2000, no visit in the previous 3 years, a confirmed diagnosis by an arthritis specialist, or having ≥ 2 visits to any physician for JRA, ≥ 2 months apart but within 2 years. Results Cumulative incidence of JRA was 17.8/100,000. Mean age at diagnosis was 9.8 ± 4.6 years, 68% were female and more persons were diagnosed in winter. Subjects had a median of 10 medical visits over the first year. Conclusion Our population based incidence estimate was similar to others. Children and adolescents with JRA are heavy users of medical care. Additional study of environmental or climate- related triggers may be warranted.

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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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)

    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.

    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

    2006-07-01

    Hydro-Quebec TransEnergie's interest in transmission line surge arresters (TLSA) was discussed. The utility conducted studies regarding the use of TLSAs to reduce outages caused by lightning in overhead transmission lines having voltages of 52 to 330 kV. It was determined that in some cases, TLSA is the only solution to reducing flashover initiated by lightning. This paper presented the results of 4 different TLSA configurations in which the impact of grounding resistance on TLSA performance was examined in an effort to determine the most effective configuration. The study revealed that lightning flashovers could be reduced by 70 per cent by installing 1 TLSA on every 2 poles of a 52 kV transmission line. The TLSA should be mounted on one pole structure and the earth wire on the unprotected poles should be removed. According to several tests conducted at Hydro-Quebec's Institut de Recherche en Electricite du Quebec (IREQ), the energy absorption capability of arresters from 4 different manufacturers proved to be at least 6 kJ/kv. The arresters failure rate was estimated to 3 per cent every time a lightning strike occurred on a transmission line. It was suggested that a 100 km long line with one pole every 60 meters should not have more than one arrester failure per year. The arresters must be installed with a mechanical device that could disconnect a failed unit from the transmission system to avoid a permanent fault on the network. It was concluded that TLSAs are useful in reducing lightning flashovers caused by lightning. However, Hydro-Quebec TransEnergie still has concerns regarding their cost, reliability, impact on line maintenance, testing difficulties in the field, mechanical stress on the conductors, and their ability to withstand dielectric behaviour under ice. tabs., figs.

    Full Text Available Abstract Background Previous research has provided evidence that socioeconomic status has an impact on invasive treatments use after acute myocardial infarction. In this paper, we compare the socioeconomic inequality in the use of high-technology diagnosis and treatment after acute myocardial infarction between the US, Quebec and Belgium paying special attention to financial incentives and regulations as explanatory factors. Methods We examined hospital-discharge abstracts for all patients older than 65 who were admitted to hospitals during the 1993–1998 period in the US, Quebec and Belgium with a primary diagnosis of acute myocardial infarction. Patients' income data were imputed from the median incomes of their residential area. For each country, we compared the risk-adjusted probability of undergoing each procedure between socioeconomic categories measured by the patient's area median income. Results Our findings indicate that income-related inequality exists in the use of high-technology treatment and diagnosis techniques that is not justified by differences in patients' health characteristics. Those inequalities are largely explained, in the US and Quebec, by inequalities in distances to hospitals with on-site cardiac facilities. However, in both Belgium and the US, inequalities persist among patients admitted to hospitals with on-site cardiac facilities, rejecting the hospital location effect as the single explanation for inequalities. Meanwhile, inequality levels diverge across countries (higher in the US and in Belgium, extremely low in Quebec. Conclusion The findings support the hypothesis that income-related inequality in treatment for AMI exists and is likely to be affected by a country's system of health care.

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

    Swine production, the second most important contributor to Quebec's agricultural revenue, faces many problems. Intensive piggeries, with up to 599 animal units, are used to raise finishing pigs for slaughter. Among the great number of gaseous species emitted to the atmospheric environment from livestock buildings and manure storage units is NH3, which is one of the most important and most offensive with respect to human health. Under appropriate meteorological and topographical conditions, gaseous contaminants can spread and cause a public nuisance--up to a 1-km radius around the farm. To mitigate these effects, the Quebec Government adopted regulations that set minimum buffer distances to be observed by any expansion of an existing or new pig farm. The objectives of this study were (i) to assess the efficiency of the current buffer distance prescriptions in Quebec in mitigating effects of air pollution from swine units and (ii) to identify potential areas for establishing pig farm operations that will not be offensive to people. The air dispersion American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) with receptors distributed at 1.6 km around each source was used first, followed by a spatial geographic information system (GIS) model. Results from the dispersion model showed that the highest hourly concentration with a 99.5% compliance frequency for a single farm was 3078.1 microg/m3 and exceeded the NH3 odor criterion hourly standard set by the Quebec Government at 183.4 microg/m3. Thus, for public safety, densely populated areas like housing developments must be located >1300 m from a pig farm. This distance is in the range of setback distances (723 to 1447 m) obtained by using abacuses defined in the L'Erable Regional County Municipality.

    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.

    1998-01-01

    The age structure of mature lake trout Salvelinus namaycush from the Wisconsin waters of Lake Superior increased following a population recovery that has taken place since the 1960s. As the population aged, it became apparent that scales were unreliable aging structures. Beginning in 1986, we examined both scale and sagittal otolith ages from tagged fish with a known period at liberty. We found large discrepancies in scale and sagittal otolith ages of mature fish, such that scale ages were biased low. We estimated lake trout living up to 42 years, which is greater than previously reported from Lake Superior. Investigators studying lake trout population dynamics in the Great Lakes should be aware that lake trout can live longer than previously thought.

    A two square kilometre catchment in a discontinuous permafrost zone near the Inuit community of Umiujaq on the eastern shore of Hudson Bay in Northern Quebec, Canada, is being investigated to determine the impact of permafrost degradation on groundwater resources. The catchment, which became deglaciated about 7500 years ago, lies in a valley which includes about 30-40 m of glacial-fluvial and marine Quaternary sediments. Permafrost mounds at the site extend from a few meters below ground surface to depths of about 10-30 m. Instrumentation has been installed to measure groundwater levels and temperature, as well as groundwater and surface water geochemistry, isotope signatures (including δ18O and 3H) and stream flow. Preliminary groundwater isotope data reflect depleted δ18O signals that differ from expected values for local groundwater, possibly representing permafrost thaw. In addition, stable water isotopes indicate evaporation from shallow thermokarst lakes. Meteorological conditions including air temperatures, precipitation and snowpack are also being monitored. Near-surface geophysical surveys using electrical resistivity tomography (ERT), induced polarization tomography (IPT), georadar and seismic refraction tomography have been carried out to characterize the catchment and to build a 3D geological site model. A numerical model of coupled groundwater flow and heat transport, including thermal advection, conduction, freeze-thaw and latent heat, is being developed for the site to help develop the conceptual model and to assess future impacts of permafrost degradation due to climate warming. The model (Heatflow/3D) includes nonlinear functions for the temperature-dependent unfrozen moisture content and relative permeability, and has been tested against analytical solutions and using benchmarks developed by the INTERFROST modelling consortium. A conceptual 2D vertical-plane model including several permafrost mounds along a 1 km section shows dynamic seasonal

  14. The Quebec Association of Gastroenterology Position Paper on Colorectal Cancer Screening - 2003

    2004-01-01

    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.

  15. Genomic characterization of a large outbreak of Legionella pneumophila serogroup 1 strains in Quebec City, 2012.

    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.

  16. Hydro-Quebec REC system: probe positioning system for heat exchanger inspection

    International Nuclear Information System (INIS)

    In 2002, Hydro-Quebec's Gentilly-2 (G2) Nuclear Power Plant commissioned the Hydro-Quebec Research Institute to integrate its SCOMPI technology into their Eddy Current heat exchanger inspection setup. The purpose of this project was to develop an automated, fast, precise, and reliable positioning device, which would be adaptable to several heat exchangers, including steam generators. Hydro-Quebec's SCOMPI robot is a portable, six axes robot, developed in 1992 for the repair and maintenance of turbine runners. Given the name 'REC System', the integrated SCOMPI robot was first used during the 2003 moderator and shut-down cooler heat exchanger inspections. In 2005, the REC System replaced its SCOMPI technology with that of the newer Mini-SCOMPI, and was afterwards used to inspect two G2 steam generators. The Mini-SCOMPI is a smaller version of the SCOMPI which allows one-man, quick and easy installation. Both the 2003 and the 2005 campaigns were successful, with the REC system integration proving to be nearly transparent to the inspection process. No failure or time losses occurred during these inspections and all of the heat exchangers' tubes were accessible. In addition, probe positioning was very efficient thanks to the Mini-SCOMPI and the vision system. In 2005, half of the tubes belonging to Steam Generators 1 and 2 were inspected from the inlet side. In the future, all heat exchanger inspections with the REC System will be performed using the Mini-SCOMPI. The 5th CNS International Steam Generator Conference provides us with an excellent forum for presenting the successful integration of a new technology into an existing system for the inspection of various types of heat exchangers.

    In recent years, after the bovine spongiform encephalopathy (BSE, or mad cow disease) crisis in Europe, and after the first case of BSE was found in Alberta, both regulation and producers’ initiatives have lead to an ever smaller demand for meat meal and animal fat used in animal feed. Meat meal and animal fat were produced in great part from the rendering of carcasses, i.e., animals that died on the farm due to disease or accident. In Quebec, agricultural producers used to sell the carcasses...

  20. Fee Increases and Target Income Hypothesis: Data from Quebec on Physicians' Compensation and Service Volumes

    Science.gov (United States)

    Contandriopoulos, Damien; Perroux, Mélanie

    2013-01-01

    Recent years have witnessed important public investments in physicians' compensation across Canada. The current paper uses data from Quebec to assess the impact of those investments on the volumes of services provided to the population. While total physician compensation costs, average physician compensation and average unit cost per service all rose extremely fast, the total number of services, number of services per capita and average number of services per physician either stagnated or declined. This pattern is compatible with the economic target income hypothesis and raises important policy questions. PMID:24359715

  4. The burgeoning field of transdisciplinary adaptation research in Quebec (1998-): a climate change-related public health narrative.

    2011-01-01

    This paper presents a public health narrative on Quebec's new climatic conditions and human health, and describes the transdisciplinary nature of the climate change adaptation research currently being adopted in Quebec, characterized by the three phases of problem identification, problem investigation, and problem transformation. 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 established during the last 13 years. The first of the two sections introduces the social context of a Quebec undergoing climate changes. Current climatic conditions and expected changes will be described, and attendant health risks for the Quebec population. The second section addresses the scientific, institutional and normative dimensions of the problem. It corresponds to a "public health narrative" presented in three phases: (1) problem identification (1998-2002) beginning in northern Quebec; (2) problem investigation (2002-2006) in which

    The reconstruction of the history of former glacial lakes is commonly based on the study of strandlines that generally consist of boulder ridges, sandy beaches and other near-shore deposits. This approach, however, is limited in some regions where the surficial geology consists of thick accumulation of fine-grained glaciolacustrine sediments that mask most deglacial landforms. This situation is particularly relevant to the study of Lake Ojibway, a large proglacial lake that developed in northern Ontario and Quebec following the retreat of the southern Laurentide ice sheet margin during the last deglaciation. The history of Ojibway lake levels remains poorly known, mainly due to the fact that this lake occupied a deep and featureless basin that favored the sedimentation of thick sequences of rhythmites and prevented the formation of well-developed strandlines. Nonetheless, detailed mapping revealed a complex sequence of discontinuous small-scale cliffs that are scattered over the flat-lying Ojibway clay plain. These terrace-like features range in size from 4 to 7 m in height and can be followed for 10 to 100's of meters. These small-scale geomorphic features are interpreted to represent raised shorelines that were cut into glaciolacustrine sediments by lakeshore erosional processes (i.e., wave action). These so-called wave-cut scarps (WCS) occur at elevations ranging from 3 to 30 m above the present level of Lake Abitibi (267 m), one of the lowest landmarks in the area. Here we evaluate the feasibility of using this type of relict shorelines to constrain the evolution of Ojibway lake levels. For this purpose, a series of WCS were measured along four transects of about 40 km in length in the Lake Abitibi region. The absolute elevation of 154 WCS was determined with a Digital Video Plotter software package using 1:15K air-photos, coupled with precise measurements of control points, which were measured with a high-precision Global Navigation Satellite System tied up to

    Quantifying periphyton (attached algal) contributions to autotrophic production in lakes is confounded by properties of substratum that affect community biomass (as chlorophyll content) and productivity. We compared chlorophyll content and productivity of natural algal communities (phytoplankton......, epipelon, epilithon, epixylon, and epiphyton) experiencing high (>10%) incident radiation in lakes in the US, Greenland, and Quebec, Canada. Chlorophyll content and productivity differed significantly among regions, but they also differed consistently among communities independent of region. Chlorophyll...... content of periphyton on hard substrata (rocks and wood) was positively related to water-column total P (TP), whereas chlorophyll content of algae on sediment (epipelon) and TP were not significantly related. Chlorophyll content was up to 100× higher on sediments than on hard substrata. Within regions...

    Objectives. The objectives of this study were to examine the spatial accessibility to alcohol outlets in Quebec and to assess the association between neighborhood level characteristics and availability of alcohol outlets. Methods. The Tobit Model was used to assess the association between neighborhood level characteristics and the availability of alcohol outlets within 500, 1000, 2000, and 3000 metres, respectively. Results. Alcohol outlets were found to be most available in the two largest metropolitan areas of the province of Quebec (Montréal and Québec City). Within 1000 metres, alcohol outlets are more available in neighbourhoods with the following characteristics: highest concentration of men, least materially deprived highest concentration of persons aged 20 years or more, and location either in a metropolitan area or in a small town. Finally, the number of bars with video lottery terminals increases with the level of social and material deprivation. Conclusion. In Québec, there is no rule governing the location of alcohol outlets. Thus, there is an abundant literature indicating that the regulation of alcohol outlet density could be an effective means of controlling risk attributable to alcohol consumption. PMID:25810946

    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.

    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.

  11. The Three Axes of Sociological Practice: The Case of French Quebec

    Directory of Open Access Journals (Sweden)

    Jean-Philippe Warren

    2009-01-01

    Full Text Available In the debate surrounding Michael Burawoy’s plea for public sociology, it is all too often presented as the opposite of the detached, purely objective observation of society. But sociology is not torn between these two poles: the political and the scientific/empirical. Rather, the discipline is structured around three fundamental axes or dimensions: professional, descriptive, and political, embodying three essential aims which, in turn, constitute the respective roles sociology can play in academia and society depending on the specific publics the discipline seeks to address. Acting as professionals, sociologists try to attain prestige by accumulating social or symbolic capital among their colleagues. If they serve science for science’s sake, they find their reward in the advancement of knowledge. If they adopt an activist political stance, they measure the value of their work on a different scale. This paper focuses specifically on French-language sociology in Quebec from the late 19th century to 1970 and argues that the dilemma of juggling these three axes, aims, and roles is one which has deeply influenced not only the discipline as a whole but the generations of Quebec sociologists who have attempted to balance these dimensions in their scholarship. There were three basic schools or approaches during this period, each embedded in the social conditions of its time. Sociologists’ public engagement depended on specific historical conditions much more than it did on personal preferences.

  12. Developing professional values: perceptions of francophone occupational therapists in Quebec, Canada.

    2016-07-01

    Objective Recent literature shows growing interest in the values displayed by occupational therapists. Yet, none of these writings has so far examined the factors that contribute to the development of occupational therapists' professional values. These factors are important, since values play a pivotal role in forging professional identity, which in the case of some occupational therapists remains somewhat ambiguous. This article proposes possible answers to the following question: What do Quebec Francophone occupational therapists perceive as the building blocks of their professional values? Methods Using a phenomenological qualitative method, the subjective experience of occupational therapists in Quebec, Canada was examined. Twenty-six occupational therapists took part in the study. Results As intended, their professional experience was varied. According to the participants, four factors contributed significantly to their professional values: professional experience, university training, personal experience, and professional development. However, fewer than 50% of the participants cited six other factors (workplace, family upbringing, personal development, personality and abilities, professional normative framework, and sociocultural background). Conclusions Most of these results are consistent with those documented in existing works. They point to the relevance of discussing professional values during university training and continuing professional development, as well as encouraging occupational therapists to become exemplars for their colleagues and interns. This study constitutes an initial step in understanding how occupational therapists' axiological identity is formed. PMID:26824179

    Large inventories of earth embankment dams that require regular maintenance and repairs are managed by both Manitoba Hydro and Hydro-Quebec. A rational procedure was developed for the allocation of limited maintenance and repairs funds while still optimizing dam safety objectives. This paper describes a procedure based on the adaptation of the Condition Indexing procedure initially developed by the United States Army Corps of Engineers, which allows for the allocation of maintenance and repair funds to the components deemed the most important and in the worst condition. The application of the Condition Index procedure was illustrated by examining a sample of different embankment dams operated by Manitoba Hydro and Hydro-Quebec. The primary failure modes are correctly identified by the Condition Index procedure, and it prioritizes the most relevant repair and maintenance activities. This paper describes, and the presents the results of, studies on an embankment dam on limestone foundation, an embankment dam on a clay foundation, and an embankment dam on alluvial soils. 5 refs., 17 tabs.

    In the early 1950s, both the publication of the first Diagnostic and Statistical Manual (DSM-I) and the advent of psychopharmacology - particularly the development of chlorpromazine (Thorazine - RP4650) - set the stage for models of psychiatric thought, research and practice that remain dominant today. It was during this pivotal period, in 1955, that the Département de psychiatrie de l'Université de Montréal was founded by a cohort of young researchers newly arrived from well-known universities in France and the northeastern United States. This influential group quickly became staunch critics of the province's religion-based asylum system and lobbied for a government review that culminated into the 1962 Commission d'étude des hôpitaux psychiatriques (popularly known as the Bédard Report). What followed in Quebec between 1965 and 1975 was the secularization of psychiatric institutions and widespread deinstitutionalization. This paper illuminates cultural changes and intellectual shifts that have been overlooked in historical studies of post-war psychiatry by exploring the expansion of such "anti-psychiatry" schools of thought in Quebec in this period.

    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) PMID:7820377

    The largest two earthquakes in eastern North America (ENA) in the last 50 years are the 2011 Mineral, Virginia and the 1988 Saguenay, Quebec earthquakes, both of moment magnitude (M) 5.8. Both events were relatively well-recorded at regional distances (especially the Virginia earthquake) but have a disappointing lack of instrumental records at distances within 50 km, confounding interpretation of expected near-source motions for moderate-to-large ENA events. At regional distances (200 to 500 km), over frequencies from 0.5 to 10 Hz, the instrumentally-recorded motions from the Virginia and Quebec earthquakes show similar amplitudes and attenuation trends; in both cases the motions agree reasonably well with the trend lines suggested by recent ground-motion prediction equations (GMPEs) such as those of Atkinson and Boore (2011) and Pezeshk et al. (2011). At distances ground motions and attenuation using intensity data; intensity data have the advantage of being available at close distances where instrumental records are sparse. Intensities for the Virginia event were approximately 1 unit lower than those for Saguenay at close distances (bounce effects being seen in a different distance range. Both events had a mean radius for intensity 3 of about 600 km. The observed mean intensity of 3 at 600 km is in agreement with the intensity GMPE of Atkinson and Wald (2007); at close distances, the Virginia intensities are lower than predicted by Atkinson and Wald (2007), whereas the Saguenay intensities are higher.

    Full Text Available Objectives. The objectives of this study were to examine the spatial accessibility to alcohol outlets in Quebec and to assess the association between neighborhood level characteristics and availability of alcohol outlets. Methods. The Tobit Model was used to assess the association between neighborhood level characteristics and the availability of alcohol outlets within 500, 1000, 2000, and 3000 metres, respectively. Results. Alcohol outlets were found to be most available in the two largest metropolitan areas of the province of Quebec (Montréal and Québec City. Within 1000 metres, alcohol outlets are more available in neighbourhoods with the following characteristics: highest concentration of men, least materially deprived highest concentration of persons aged 20 years or more, and location either in a metropolitan area or in a small town. Finally, the number of bars with video lottery terminals increases with the level of social and material deprivation. Conclusion. In Québec, there is no rule governing the location of alcohol outlets. Thus, there is an abundant literature indicating that the regulation of alcohol outlet density could be an effective means of controlling risk attributable to alcohol consumption.

    Referral prioritisation is commonly used in home-based occupational therapy to minimise the negative impacts of waiting, but this practice is not standardised. This may lead to inequities in access to care, especially for clients considered as low priority, who tend to bear the brunt of lengthy waiting lists. This cross-sectional study aimed to describe waiting list management practices targeting low-priority clients in home-based occupational therapy in the province of Quebec, Canada, and to investigate the association between these practices and the length of the waiting list. A structured telephone interview was conducted in 2012-2013 with the person who manages the occupational therapy waiting list in 55 home care programmes across Quebec. Questions pertained to strategies aimed at servicing low-priority clients, the date of the oldest referral and the number of clients waiting. Results were analysed using descriptive statistics and non-parametric tests. The median wait time for the oldest referral was 18 months (range: 2-108 months). A variety of strategies were used to service low-priority clients. Programmes that used no strategies to service low-priority clients (n = 16) had longer wait times (P occupational therapy programmes. However, in programmes where none of these strategies are used, low-priority clients may be denied access to services indefinitely.

    2016-04-01

    Full Text Available Background: Fragmentation and lack of coordination often occur among organisations offering treatment for individuals with substance-use disorders. Better integration from a system perspective within a network of organisations offering substance-use disorder services can be developed using various integration strategies at the administrative and clinical levels. This study aims to identify integration strategies implemented in Quebec substance-use disorder networks and to assess their strengths and limitations. Methods: A total of 105 stakeholders representing two regions and four local substance-use disorder networks participated in focus groups or individual interviews. Thematic qualitative and descriptive quantitative analyses were conducted. Results: Six types of service integration strategies have been implemented to varying degrees in substance-use disorder networks. They are: 1 coordination activities-governance, 2 primary-care consolidation models, 3 information and monitoring management tools, 4 service coordination strategies, 5 clinical evaluation tools and 6 training activities. Conclusion: Important investments have been made in Quebec for the training and assessment of individuals with substance-use disorders, particularly in terms of support for emergency room liaison teams and the introduction of standardised clinical evaluation tools. However, the development of integration strategies was insufficient to ensure the implementation of successful networks. Planning, consolidation of primary care for substance-use disorders and systematic implementation of various clinical and administrative integration strategies are needed in order to ensure a better continuum of care for individuals with substance-use disorders.

    Montreal-based Helimax Energy Inc., a private wind energy consulting firm, conducted a study to determine Quebec's wind potential, the price of wind produced electricity and the economic payback resulting from the installation of a 1000 MW or a 4000 MW wind farm. The study was based on 3 assumptions that the wind turbine arrays would be installed from 2008 to 2010, that each turbine would produce at least 3 MW of electricity, and that the forecasted price reduction of wind energy would be 2.5 per cent per year. A rigorous method comprising eleven steps was developed to determine the wind potential for each of the 17 administrative regions in Quebec. Wind resources were classified as exceptional for winds of 9 metres per second or more; excellent for winds of 8 to 9 metres per second; and, very good quality for winds of 7 to 8 metres per second. The evaluation method was based on Geographic Information System (GIS) technology and mesoscale wind speed maps. Of all the administrative regions in Quebec, the North Shore has the highest wind potential with 77 per cent of all wind moving at 7 metres per second or greater. Second ranking went to the Lower St. Lawrence, Gaspe Peninsula and Magdalen Islands. In addition to employment opportunities, the economic payback for constructing 1000 MW or 4000 MW wind farms in Quebec include industrial and regional development, development of wind expertise in the province and reduction of greenhouse gas emissions. 25 tabs., 23 figs.

  15. Paper presented to the Commission des transports et de l'environnement in the context of the general consultation concerning the implementation of the Kyoto Protocol in Quebec

    International Nuclear Information System (INIS)

    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

  16. Effects of acid precipitation on a boreal forest ecosystem. Ion budgets and changes in water chemistry for the Laflamme Lake watershed

    Energy Technology Data Exchange (ETDEWEB)

    Papineau, M.

    1987-01-01

    Data on surface waters have been gathered at the Laflamme Lake Watershed in Quebec as part of an ion budget research program. This watershed was set up in 1980 to assess the effects of long range transport of airborne pollutants on a boreal forest ecosystem receiving moderate to high sulphate loading. Precipitation data indicates that between 1981 and 1984, the average pH of water falling onto the watershed was 4.4, that precipitation quality is cyclic and that loading is episodic. The main components of precipitation on an equivalent basis are sulfate, hydrogen, nitrate and ammonium ions. ALthough the sulphate to nitrate ration is 2:1 on a yearly basis, nitrate ions are more important than sulphates in January. Since water and pollutants build up in the snowpack, spring melt is a critical period during which concentrations in surface waters and exports from the watershed are modifed for many parameters especially hydrogen and bicarbonate ions. Lake water quality is characteristic of lakes that are very sensitive to acidification. High sulfate values seem to indicate that the watershed has been affected by atmospheric loading. The average pH of the lake (6.4) indicates that the lake is not yet greatly acidified. Important buffering occurs in the soil and surficial deposits of the watershed. Stream water is slightly less mineralized, slightly more acidic and shows more pronounced changes in water quality than lake water. Over the last five years, sulfate, conductivity and some heavy metal levels have increased in surface waters while no significant trends were seen for pH and alkalinity. In other Quebec monitoring lakes, trends of decreasing pH were seen during this period. When wet loading is compared to stream output, hydrogen and nitrate ions are seen to be retained in the watershed while Ca, Mg, Na, K, sulphate and chloride are lost. 63 refs. 31 figs. 32 tabs.

  17. The Ne3LS Network, Quebec's initiative to evaluate the impact and promote a responsible and sustainable development of nanotechnology

    International Nuclear Information System (INIS)

    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 (Ne3LS) are emerging worldwide. In Quebec, Canada, a Task Force was mandated by NanoQuebec to conceive a Ne3LS 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 Ne3LS. Their resulting action plan, made public in November 2006, contained several recommendations, including the creation of a knowledge network (Ne3LS Network). In the following years, after consulting with numerous key players concerned with the possible impacts of nanosciences and nanotechnologies in Quebec, the Ne3LS 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 Ne3LS research activities (grants and fellowships); 2) Spearhead the Canadian and international Ne3LS 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.

    Vivre en Ville is a group of 225 activists from Quebec's health, environment, transportation and education sectors that promote sustainable living in the urban areas of the province. Their recommendations to save energy are based on principles of energy efficiency and combining resources to promote the use of common transportation corridors, diversified urban living and the protection and renovation of heritage sites. In addition to promoting the creation of parks and green spaces in urban areas, the group encourages residents to engage in municipal affairs by demanding solutions to transportation problems. Among their recommendations are a moratorium on the construction of new highways; upgrade existing mass transit systems to minimize personal vehicle use; increase funding for public transport; promote light rail transit to suburban areas; and devote special road lanes to collective transport such as taxis, buses and car pools. Other recommendations include the creation of more bicycle paths and centres that offer bikers shower and locker facilities. The group also believes that companies with more than 30 employees should be required to have transportation policies for its employees, such as organized car pools. Vivre en Quebec claims that too much energy has already been wasted and more action should be taken to implement these recommendations. tabs.

  19. Summer outdoor temperature and occupational heat-related illnesses in Quebec (Canada)

    International Nuclear Information System (INIS)

    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

    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

In Quebec, social work has been part of the debate facing two mainstream politics, the canadian one based on multiculturalism and, in Quebec, on interculturalism. The article intends to give a historical perspective on how social work had to deal with different contradictions.

    Full Text Available EnglishCohabitation has become so prevalent in Canada that it is now the most commonmode of entry into conjugality. Yet in drawing comparisons across Canadianprovinces, cohabitation is far more prevalent in the province of Quebec thanelsewhere. With this in mind, the purpose of the current paper is three fold. First,we set out to briefly situate the recent growth in the number of common-lawunions in Canada and Quebec into a broader historical and international context.Secondly, we review available information from the 2001 Census and the 1998General Social Survey on some of the key socioeconomic and demographiccharacteristics of persons who cohabit relative to those that marry. Thirdly, weconsider how these changes are important to public policy, and of direct interest to legislators andthe Canadian legal system. Major differences are documentedin comparing Quebec with elsewhere in Canada in terms of the education, laborforce participation, median income, income poverty and homeownership. Thedifferences documented between persons who marry relative to cohabiters arefound to be much less in Quebec than elsewhere, in a context wherebycohabitation has become far more widespread, an observation with directimplications for public policy.FrenchLa cohabitation est devenue tant prévalente au Canada qu’elle représenteactuellement le mode d’entrée dans la vie conjugale le plus répandu.

  5. Environmental assessment and viable interdependence: the Great Whale River case in northern Quebec (First Nations)

    Energy Technology Data Exchange (ETDEWEB)

    Mulvihill, P. R.

    1997-12-31

    This study is based on the belief that environmental assessment (EA) can be supportive of viable interdependence between regions and cultures. The central focus is on the scoping stage of the EA conducted for the proposed Great Whale hydroelectric project in northern Quebec. The evaluative framework consists of 16 criteria divided into three interrelated categories, i.e. substantive, general process-oriented and specific process-oriented. The specific process-oriented criteria constitute the primary analytical focus and are the subject of five separate sub-analysis, which reveal various strengths and weaknesses in the performance of the case study. It was concluded that environmental assessment in an intercultural setting is largely within the control of EA panels and the key shortcoming of the process, namely the lack of dialogue between the proponents and the intervenors, could be addressed by making public hearings more dynamic and interactive.

  6. La gestion des gestionnaires de projets: Le cas de l'industrie aerospatiale au Quebec

    Science.gov (United States)

    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

    When decision-makers are engaged in a polarized discourse and leaving aside evidence-based recommendations, is there a role for researchers in the dissemination of this scientific evidence to the general public as a means to counterbalance the debate? In response to the controversial Bill 10 in Quebec, we developed and posted a knowledge transfer video on YouTube to help stimulate critical public debate. This article explains our approach and methodology, and the impact of the video, which, in the space of two weeks, had more than 9,500 views, demonstrating the pertinence of such initiatives. We conclude with recommendations for other research groups to engage in public debates. PMID:27232235

  8. Impact of pneumococcal vaccines use on invasive pneumococcal disease in Nunavik (Quebec from 1997 to 2010

    Directory of Open Access Journals (Sweden)

    Jean-Baptiste Le Meur

    2014-01-01

    Full Text Available Background: In 2000, an outbreak of severe pneumonia caused by a virulent clone of serotype 1 Streptococcus pneumoniae was detected in the Nunavik region of Quebec. A mass immunization campaign was implemented in the spring of 2002, targeting persons ≥5 years of age and using the 23-valent pneumococcal polysaccharide vaccine (PPSV23. At the same time, the 7-valent pneumococcal conjugate vaccine (PCV7 was introduced into the routine immunization programme of infants, with catch-up for children up to 4 years of age. Objectives: To describe the epidemiology of invasive pneumococcal disease (IPD in relation to PPSV23 and PCV7 use. Study design and methods: Retrospective analysis of IPD cases identified by the Quebec public health laboratory during the period 1997–2010. Results: A total of 82 IPD cases were identified during the study period. In adults, serotype 1 incidence decreased following the 2002 PPSV23 mass campaign but breakthrough cases continued to occur. Following PCV7 use in children, there was a decrease in the incidence of vaccine-type IPD and replacement by other serotypes in adults. In children, a marked decrease in the annual incidence of serotypes included in PCV7 was observed following PCV7 introduction: 162/100,000 in 1997–2001 vs. 10/100,000 in 2004–2010 (p<0.01. Concomitantly, the incidence of IPD caused by serotypes not included in PCV7 increased from 29/100,000 to 109/100,000 (p=0.11. Conclusion: The mass immunization campaign using the PPSV23 in 2002 and the introduction of PCV7 for the routine immunization of infants induced important modifications in the epidemiology of IPD. IPD rates in Nunavik remain much higher than in the southern part of the province both in children and adults. More effective pneumococcal vaccines are needed to eliminate geographic disparities in IPD risk.

    Auger, Nathalie; Park, Alison L.; Zoungrana, Hamado; McHugh, Nancy Gros-Louis; Luo, Zhong-Cheng

    2013-01-01

    Background: Inuit and First Nations populations have higher rates of stillbirth than non-Aboriginal populations in Canada do, but little is known about the timing and cause of stillbirth in Aboriginal populations. We compared gestational age– and cause-specific stillbirth rates in Inuit and First Nations populations with the rates in the non-Aboriginal population in Quebec. Methods: Data included singleton stillbirths and live births at 24 or more gestational weeks among Quebec residents from 1981 to 2009. We calculated odds ratios (ORs), rate differences and 95% confidence intervals (CIs) for the retrospective cohort of Inuit and First Nations births relative to non-Aboriginal births using fetuses at risk (i.e., ongoing pregnancies) as denominators and adjusting for maternal characteristics. The main outcomes were stillbirth by gestational age (24–27, 28–36, ≥ 37 wk) and cause of death. Results: Rates of stillbirth per 1000 births were greater among Inuit (6.8) and First Nations (5.7) than among non-Aboriginal (3.6) residents. Relative to the non-Aboriginal population, the risk of stillbirth was greater at term (≥ 37 wk) than before term for both Inuit (OR 3.1, 95% CI 1.9 to 4.8) and First Nations (OR 2.6, 95% CI 2.1 to 3.3) populations. Causes most strongly associated with stillbirth were poor fetal growth, placental disorders and congenital anomalies among the Inuit, and hypertension and diabetes among the First Nations residents. Interpretation: Stillbirth rates in Aboriginal populations were particularly high at term gestation. Poor fetal growth, placental disorders and congenital anomalies were important causes of stillbirth among the Inuit, and diabetic and hypertensive complications were important causes in the First Nations population. Prevention may require improvements in pregnancy and obstetric care. PMID:23422443

  10. Masters of convenience: competition, including a rising star from Quebec, improves the service station breed

    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.

    Waste stabilisation ponds (WSPs) are highly enriched environments that may emit large quantities of greenhouse gases (GHG), including CO2, CH4 and N2O. However, few studies provide detailed reports on these emissions. In the present study, we investigated GHG emissions from WSPs in Western Australia and Quebec, Canada, and compared emissions to WSPs from other climatic regions and to other types of aquatic ecosystems. Surface water GHG concentrations were related to phytoplankton biomass and nutrients. The CO2 was either emitted or absorbed by WSPs, largely as a function of phytoplankton dynamics and strong stratification in these shallow systems, whereas efflux of CH4 and N2O to the atmosphere was always observed albeit with highly variable emission rates, dependent on treatment phase and time of the day. The total global warming potential index (GWP index, calculated as CO2 equivalent) of emitted GHG from WSPs in Western Australia averaged 12.8 mmol m(-2) d(-1) (median), with CO2, CH4 and N2O respectively contributing 0%, 96.7% and 3.3% of the total emissions, while in Quebec WSPs this index was 194 mmol m(-2) d(-1), with a relative contribution of 93.8, 3.0 and 3.2% respectively. The CO2 fluxes from WSPs were of the same order of magnitude as those reported in hydroelectric reservoirs and constructed wetlands in tropical climates, whereas CH4 fluxes were considerably higher compared to other aquatic ecosystems. N2O fluxes were in the same range of values reported for WSPs in subtropical climate. PMID:27258617

  12. Contagious comments: what was the online buzz about the 2011 Quebec measles outbreak?

    Directory of Open Access Journals (Sweden)

    Jennifer A Pereira

    Full Text Available BACKGROUND: Although interruption of endemic measles was achieved in the Americas in 2002, Quebec experienced an outbreak in 2011 of 776 reported cases; 80% of these individuals had not been fully vaccinated. We analyzed readers' online responses to Canadian news articles regarding the outbreak to better understand public perceptions of measles and vaccination. METHODS: We searched Canadian online English and French news sites for articles posted between April 2011 and March 2012 containing the words "measles" and "Quebec". We included articles that i concerned the outbreak or related vaccination strategies; and ii generated at least ten comments. Two English and two bilingual researchers coded the unedited comments, categorizing codes to allow themes to emerge. RESULTS: We analyzed 448 comments from 188 individuals, in response to three French articles and six English articles; 112 individuals expressed positive perceptions of measles vaccination (2.2 comments/person, 38 were negative (4.2 comments/person, 11 had mixed feelings (1.5 comments/person, and 27 expressed no opinion (1.1 comments/person. Vaccine-supportive themes involved the success of vaccination in preventing disease spread, societal responsibility to vaccinate for herd immunity, and refutation of the autism link. Those against measles vaccination felt it was a personal rather than societal choice, and conveyed a distrust of vaccine manufacturers, believing that measles infection is not only safe but safer than vaccination. Commenters with mixed feelings expressed uncertainty of the infection's severity, and varied in support of all vaccines based on perceived risk/benefit ratios. CONCLUSION: The anti-vaccine minority's volume of comments translates to a disproportionately high representation on online boards. Public health messages should address concerns by emphasizing that immunization is always a personal choice in Canada, and that the pharmaceutical industry is strictly

    Full Text Available Byssinosis, a chronic lung disease of cotton mill workers, is characterized by repeated episodes of reversible airway obstruction, which can lead to permanent alterations of lung function. When this occurs in Quebec the worker must be removed from further exposure in accordance with the provincial compensation rules. The current Quebec Occupational Safety and Health Regulation has a permissible exposure limit of 500 μg/m3, resulting in a prevalence rate of byssinosis of 2% to 5% in cotton workers. In this study the incidence of new respiratory disorders in persons employed in Quebec cotton mills from 1980 to 1995 was assessed and factors that identified byssinosis cases were analyzed. Incidence of the disease was assessed on the basis of cases referred to the Commission de Santé & Sécurité au travail du Québec (Quebec Workers’ Compensation Board from all Quebec textile plants. Analyses of age, years of employment, job description, smoking history, bronchial reactivity and lung function before and at work were used for diagnostic purposes. Incidence of new byssinosis cases from 1990 to 1995 was 2.8 cases per year per 5000 workers, slightly above the incidence from 1980 to 1989, at 1.7 cases per year. The incidence of chronic cases was stable at 1.5 cases per year, whereas that of early cases increased from 0.3 cases per year (1980 to 1989 to 1.25 cases per year (1990 to 1995. In comparison with chronic byssinosis cases, the average time of work before symptom appearance was 17±4 versus 32±1 years, P<0.001. Bronchial reactivity to methacholine (PC20 at work was below 2 mg/mL in 100% of byssinosis cases versus 14% in subjects not diagnosed with byssinosis. Decreases in forced expiratory volume in 1 s (FEV1 at work averaged 30% in the byssinosis and 6% in the nonbyssinosis subjects; peak flow rates were not different between those with and those without byssinosis. Early byssinosis cases were from three distinct plants in different

    The first rainbow smelt (Osmerus mordax) to enter Lake Ontario were probably migrants from an anadromous strain introduced into New York's Finger Lakes. Since the upper Great Lakes were originally stocked with a landlocked strain from Green Lake, Maine, subsequent migration to Lake Ontario from Lake Erie makes Lake Ontario unique among the Great Lakes in probably having received introductions from two distinct populations.

    2011-03-01

    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.

    2010-01-01

    An ethnographic study was undertaken in two rural areas of Quebec to conceptualize the good death. The findings reveal that a good quality of life for the dying person and his or her family and friends is essential for a good death. The resulting conceptual model emphasized four dimensions: physical, spiritual, social, and emotiona/psychological. These dimensions were determined to be similar to those discovered through a previous urban study, indicating that there may be considerable overlap between good deaths in rural and urban areas. Some findings of this Quebec French-language rural study were similar to those of an Alberta English-language rural study, indicating that rural people may have some common needs and interests with regard to the good death. As such, there could be some common elements of the good death that transcend culture or ethnicity. Chief among these is the desire of rural people to die at home or in their home communities.

  11. Low Fertility in Canada: The Nordic Model in Quebec and the U.S. Model in Alberta

    Directory of Open Access Journals (Sweden)

    Roderic Beaujot

    2010-01-01

    Full Text Available Among the factors that are responsible for low fertility, the risks experienced by young people are particularly relevant. In that context, it is noteworthy that fertility is rising most in Alberta and Quebec, that is in provinces where young families have had the security of either good job opportunities or supportive social policy. The fertility trend in Canada has seen a low point of 1.51 in 2002, rising to a total fertility rate of 1.66 in 2007. The trends and differences are placed in the context of family and work questions, including the division of paid and unpaid work by gender. By marital status, family structure and work orientation, fertility is highest for women and men who are married, with no step children and intermediate work orientation. We summarize the changing policy context, proposing that social policy has become more supportive of families with young children, especially in Quebec but also in the rest of Canada.

    2016-10-01

    This article reports the results of a study on the outcomes of the Canada-Quebec Infrastructure Works 2000 Program (CQIWP), an infrastructure grant program to Quebec municipalities. The focus of this study is on the effects of the CQIWP on municipal investment and physical conditions of drinking water systems and, as such, it goes beyond the usual emphasis on the fiscal consequences of intergovernmental grants. The study results show that the CQIWP was an efficient tool to induce municipalities to increase investment and to reduce the number of aqueduct breakdowns. In light of these findings, this study suggests that upper levels of governments can rely on infrastructure grants to fill the gap in municipal investment and, therefore, to improve the availability and quality of municipal infrastructure.

    This paper presents a public health narrative on Quebec's new climatic conditions and human health, and describes the transdisciplinary nature of the climate change adaptation research currently being adopted in Quebec, characterized by the three phases of problem identification, problem investigation, and problem transformation. 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 established during the last 13 years. The first of the two sections introduces the social context of a Quebec undergoing climate changes. Current climatic conditions and expected changes will be described, and attendant health risks for the Quebec population. The second section addresses the scientific, institutional and normative dimensions of the problem. It corresponds to a "public health narrative" presented in three phases: (1) problem identification (1998-2002) beginning in northern Quebec; (2) problem investigation (2002-2006) in which

    Musculoskeletal disorders are among the leading causes of work-related physical disability in the province of Quebec in Canada. The authors conducted a focus group study with physiotherapists and physical rehabilitation therapists working with patients whose treatments are compensated by the Quebec Workers' Compensation Board with the goal of exploring quality of care and ethical issues. Three main themes were identified: (1) systemic factors, (2) complexity in treatment decisions and (3) inequality of care. Although physiotherapy professionals strive to give these patients the best possible care, patients might not always be provided with optimal or equal treatment. When compared with other patients, there appear to be differences with respect to access to care and types of services offered to injured workers, raising equity concerns. Factors that shape and constrain quality of physiotherapy services for injured workers need to be addressed to improve care for these patients.

  15. Les cooperatives et l'electrification rurale du Quebec, 1945--1964

    Dorion, Marie-Josee

    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. Malgre des hesitations et quelques delais introduits par un manque de connaissances techniques et de personnel qualifie, les commissaires de l'OER se revelent perspicaces et parviennent a mettre sur pied un systeme cooperatif d'electrification rurale qui produit des resultats rapides. Il leur faudra cependant compter sur l'aide des autres acteurs engages

  16. Identity profiles and well-being of multicultural immigrants: The case of Canadian immigrants living in Quebec

    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.

    Canada is a country with two official languages, French and English. The need for both languages in Quebec and the Rest-of-Canada (ROC) generates a demand for bilingualism and investment in the acquisition of a second official language. Knowledge of an additional language may be associated with enhanced earnings because it may reflect what might generically be called ‘ability’ bias or because it may actually be useful at the workplace. Until now, available data did not indicate whether biling...

    Recent literary manifestos claim that “the center is no longer the center” (Le Devoir 2007). Indeed, it is generally admitted that Quebec literature has been more or less independent from the French field since the 1970’s. However, the analysis of the translation of this literature –its international circulation, and the almost compulsory stopover in France before being selected for translation by the agents of other literary fields– reveals various mechanisms through which the French symboli...

  20. Whole-of-society approach for public health policymaking: a case study of polycentric governance from Quebec, Canada.

    In adopting a whole-of-society (WoS) approach that engages multiple stakeholders in public health policies across contexts, the authors propose that effective governance presents a challenge. The purpose of this paper is to highlight a case for how polycentric governance underlying the WoS approach is already functioning, while outlining an agenda to enable adaptive learning for improving such governance processes. Drawing upon a case study from Quebec, Canada, we employ empirically developed concepts from extensive, decades-long work of the 2009 Nobel laureate Elinor Ostrom in the governance of policy in nonhealth domains to analyze early efforts at polycentric governance in policies around overnutrition, highlighting interactions between international, domestic, state and nonstate actors and processes. Using information from primary and secondary sources, we analyze the emergence of the broader policy context of Quebec's public health system in the 20th century. We present a microsituational analysis of the WoS approach for Quebec's 21st century policies on healthy lifestyles, emphasizing the role of governance at the community level. We argue for rethinking prescriptive policy analysis of the 20th century, proposing an agenda for diagnostic policy analysis, which explicates the multiple sets of actors and interacting variables shaping polycentric governance for operationalizing the WoS approach to policymaking in specific contexts.

  1. Development of a methodology to evaluate probable maximum precipitation (PMP) under changing climate conditions: Application to southern Quebec, Canada

    Climate change (CC) needs to be accounted for in the estimation of probable maximum floods (PMFs). However, there does not exist a unique way to estimate PMFs and, furthermore the challenge in estimating them is that they should neither be underestimated for safety reasons nor overestimated for economical ones. By estimating PMFs without accounting for CC, the risk of underestimation could be high for Quebec, Canada, since future climate simulations indicate that in all likelihood extreme precipitation events will intensify. In this paper, simulation outputs from the Canadian Regional Climate Model (CRCM) are used to develop a methodology to estimate probable maximum precipitations (PMPs) while accounting for changing climate conditions for the southern region of the Province of Quebec, Canada. The Kénogami and Yamaska watersheds are herein of particular interest, since dam failures could lead to major downstream impacts. Precipitable water (w) represents one of the key variables in the estimation process of PMPs. Results of stationary tests indicate that CC will not only affect precipitation and temperature but also the monthly maximum precipitable water, wmax, and the ensuing maximization ratio used for the estimation of PMPs. An up-to-date computational method is developed to maximize w using a non-stationary frequency analysis, and then calculate the maximization ratios. The ratios estimated this way are deemed reliable since they rarely exceed threshold values set for Quebec, and, therefore, provide consistent PMP estimates. The results show an overall significant increase of the PMPs throughout the current century compared to the recent past.

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

    2013-12-01

    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

  3. Power from the north: The poetics and politics of energy in Quebec

    Science.gov (United States)

    Desbiens, Caroline

    In 1971, Robert Bourassa, then Premier of Quebec, launched a major hydroelectric scheme to be built 1400 km North of Montreal. Known as the "James Bay" project, the first phase included the creation of eight powerhouses, six reservoirs and the diversion of two rivers. These transformations necessarily impacted the local Cree people; a territorial agreement partly compensated them but remains controversial to this day. While northern communities overwhelmingly bear the ecological cost of the project, the bulk of James Bay energy flows south to the industrial centers of Quebec, Ontario and the U.S. The assertion then that "James Bay belongs to all the Quebecois" which was meant to ease political tensions about the project begs the question, "Who are the Quebecois" and how do the Crees fit within such a community? This thesis explore that question by looking at the Quebecois cultural production of territory and its resources in the north. If James Bay was out of reach, it was never out of view. Media and political discourses reiterated key elements of a Quebecois cultural relationship to place, some of which are contained in the rural literature known as the roman de la terre. Several elements of this literature and its broader context were recontextualized in James Bay, particularly as they pertained to the will to occupy the land and develop natural resources. This was an important aspect of making James Bay---a land historically inhabited by the Crees---into a "Quebecois" national landscape. I suggest that this process was largely rooted in representations of nature that sought to bind it with nation and national identity. Thus James Bay demonstrates the close connection between identity and environmental struggles. For the Quebecois, the access to James Bay was supported by a territorial discourse that performed their own cultural past. This provoked an organized resistance from the Crees which constituted them as a modern political unit. A look at the cultural

    2014-01-01

    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.

    We used a comparative data set for 25 lakes in Denmark sampled during summer to explore the influence of lake morphometry, catchment conditions, light availability and nutrient input on lake metabolism. We found that (1) gross primary production (GPP) and community respiration (R) decline with lake...... area, water depth and drainage ratio, and increase with algal biomass (Chl), dissolved organic carbon (DOC) and total phosphorus (TP); (2) all lakes, especially small with less incident light, and forest lakes with high DOC, have negative net ecosystem production (NEP <0); (3) daily variability of GPP...... decreases with lake area and water depth as a consequence of lower input of nutrients and organic matter per unit water volume; (4) the influence of benthic processes on free water metabolic measures declines with increasing lake size; and (5) with increasing lake size, lake metabolism decreases...

  11. Lake whitefish and lake herring population structure and niche in ten south-central Ontario lakes

    Science.gov (United States)

    Carl, Leon M.; McGuiness, Fiona

    2006-01-01

    This study compares simple fish communities of ten oligotrophic lakes in south-central Ontario. Species densities and population size structure vary significantly among these lake communities depending on fish species present beyond the littoral zone. Lake whitefish are fewer and larger in the presence of lake herring than in their absence. Diet analysis indicates that lake whitefish shift from feeding on both plankton and benthic prey when lake herring are absent to a primarily benthic feeding niche in the presence of lake herring. When benthic round whitefish are present, lake whitefish size and density decline and they move lower in the lake compared to round whitefish. Burbot are also fewer and larger in lakes with lake herring than in lakes without herring. Burbot, in turn, appear to influence the population structure of benthic coregonine species. Lower densities of benthic lake whitefish and round whitefish are found in lakes containing large benthic burbot than in lakes with either small burbot or where burbot are absent. Predation on the pelagic larvae of burbot and lake whitefish by planktivorous lake herring alters the size and age structure of these populations. As life history theory predicts, those species with poor larval survival appear to adopt a bet-hedging life history strategy of long-lived individuals as a reproductive reserve.

    2009-01-01

    As social elements of our environment, mass media are regarded as determinants of individual and population beliefs, social norms and habits. Since it is recognized that they influence population health, this study aims to obtain a better portrait of Quebec media content regarding physical activity and nutrition messages on a public health level. First, we analyzed the content of fictional television shows (n = 1 3) and advertisements broadcast during those shows (n = 68). Second, we reviewed the content of La Presse newspaper and of French television Société Radio-Canada from 1986 to 2005 with regard to physical activity and nutrition messages. Our results indicate a difference between how men and women are portrayed on French television, with women more often being shown as underweight and men as at or above healthy body weight. The results also show that during the 20-year period of the reviewed content, there were fewer messages about physical activity than about nutrition. To be successful in their goal of improving population health, mass media should address both subjects together in their messages. PMID:19507724

    The feline AB blood group system has clinical significance because type B cats have natural alloimmune anti-A antibodies which can cause isoerythrolysis of the newborn and life-threatening transfusion reactions. In the United States, the prevalence of type B blood is estimated to be 1% to 2%. This study determined the prevalence of feline AB blood groups among 207 potential blood donor cats that included 178 domestic cats, in the Montreal area of Quebec, Canada. Blood typing was performed using a standardized tube technique. Blood types AB and B were confirmed using a backtyping technique. The frequency of blood types among the studied population was as follows: 95.2% type A, 4.4% type B, and 0.48% type AB. Among domestic cats, the frequency was 94.4% for type A, 5% for type B, and 0.6% for type AB. The frequency of type B was higher than expected, which reinforces the recommendation to ensure blood compatibility of the recipient and donor before transfusion through typing and possibly cross-matching as well.

    SummaryRestoration efforts at peatlands drained for peat extraction attempt to return the hydrological conditions necessary for Sphagnum moss regeneration. One year of pre-restoration monitoring (1999) and three years of post restoration monitoring were done at the Bois-des-Bel peatland near Riviere-du-Loup, Quebec, to evaluate hydrological changes that occurred at a managed section (restored site) relative to an adjacent abandoned section of the same peatland (unrestored site). Restored site evaporation was 74%, 74%, and 98% of unrestored site evaporation in 2000, 2001, and 2002, while runoff at the restored site was 83%, 30%, and 12% of unrestored site runoff over the same period. Seasonal soil volume change (swelling and shrinking of the peat) was evident at the restored site indicating rewetting of the peat profile despite the prolonged period between site abandonment and the initiation of the restoration measures (19 years). Site rewetting may have benefited from the relatively deep layer of residual peat (around 1.5 m). Higher seasonal mean water table and soil moisture were observed at the restored site relative to the unrestored site in 2000 through 2002 along with increased seasonal variability at the former location. Mean soil-water pressure was also higher than at the unrestored site and the range decreased, both spatially and on a seasonal and daily basis. The restoration techniques contributed to the recovery of hydrological conditions necessary for Sphagnum recolonization, though successful application at different sites may be limited by specific peat and climate characteristics.

  17. Integration of OHS into Risk Management in an Open-Pit Mining Project in Quebec (Canada

    2011-09-01

    Full Text Available Despite undeniable progress, the mining industry remains the scene of serious accidents revealing disregard for occupational health and safety (OHS and leaving open the debate regarding the safety of its employees. The San José mine last collapse near Copiapó, Chile on 5 August 2010 and the 69-day rescue operation that followed in order to save 33 miners trapped underground show the serious consequences of neglecting worker health and safety. The aim of this study was to validate a new approach to integrating OHS into risk management in the context of a new open-pit mining project in Quebec, based on analysis of incident and accident reports, semi-structured interviews, questionnaires and collaborative field observations. We propose a new concept, called hazard concentration, based on the number of hazards and their influence. This concept represents the weighted fraction of each category of hazards related to an undesirable event. The weight of each category of hazards is calculated by AHP, a multicriteria method. The proposed approach included the creation of an OHS database for facilitating expert risk management. Reinforcing effects between hazard categories were identified and all potential risks were prioritized. The results provided the company with a rational basis for choosing a suitable accident prevention strategy for its operational activities.

  18. Table of tables of Hydro-Quebec customer needs: Support guide, June 1993

    International Nuclear Information System (INIS)

    Hydro-Quebec conducted surveys of its direct and indirect customers concerning their needs and expectations. Direct customers are those who have a business relationship with the utility and include residential, commercial, industrial, and institutional customers, large corporations, and neighboring utilities. Indirect customers are agencies whose regulatory authority applies to the utility. These agencies fall into the categories of nuclear energy, environment and land use development, products and services, and occupational health and safety. Using techniques including group discussions, interviews, and telephone surveys, direct customers were asked to define the features of the goods and services they expect from the utility. The importance of elements such as customer treatment, rates, energy conservation programs, payment terms, and behavior of utility personnel were evaluated and ranked. For indirect customers, their requirements were determined and the importance of each was evaluated by corporate experts. The impact of the utility's performance on meeting customer needs was then evaluated in five areas: sales and quality of service, supply of electricity, safety, price, and social responsibility. Results of the 1993 survey are presented, by customer category, and compared to results of the 1992 survey. 21 tabs

  19. Crystallization and emplacement of the Lac St-Jean anorthosite massif (Quebec, Canada)

    1981-05-01

    The Lac St-Jean anorthosite massif underlies an area of over 20,000 km2 and has been emplaced into migmatitic gneisses of the central granulite terrain of the Grenville Province of the Canadian shield. Field data and petrography in an area straddling the anorthosite-gneiss contact, close to Chicoutimi (Quebec) permits an outline of its tecto-magmatic evolution. Depositional magmatic textures in the massif reveals that it crystallized from a magma in a relatively calm tectonic environment. The absence of fusion in pelitic gneisses at the contact proves that the crystallization did not take place at the level presently exposed. The parallelism of subvertical foliation in the enveloping gneisses and the anorthosite indicates that both were deformed together. It is suggested that the deformation results from a diapiric ascent of the anorthosite massif after its consolidation at depth. The depth of consolidation of the anorthosite is estimated at ˜ 25 30 km from subsolidus reaction between plagioclase and olivine. The diapiric ascent is further substantiated by the fact that three sets of mafic dykes of different ages, intrusive into the anorthosite, have a mineralogy which indicates successively decreasing P, T conditions of emplacement from granulite fades to amphibolite facies. An evolution of the basement gneisses and the anorthosite is proposed as a working hypothesis; it relies on the fact that metabasite dyke swarms in the basement gneisses represent a period of major crustal extension and could be used as a stratigraphic subdivision of the Grenville Province.

    Full Text Available Abstract Background In Canada, targeted vaccination of at risk groups for hepatitis A (HA is done since the mid 1990s resulting in declining incidence. This study estimated the year and age specific hospitalization rates and distribution of risk factors for HA in Quebec, Canada, between 1990 and 2003. Methods Records of patients hospitalized with HA-related diagnostic codes were retrieved from the provincial database. Hospital charts of all deceased cases and a random sample of all other records were reviewed. Results From 1503 hospitalization records, 573 charts were reviewed including 49 (91% of the 54 deceased patients. Confirmed acute HA was present in 79% of records where HA was the primary diagnosis, and in 3%–8% of records where HA was a secondary diagnosis. From the total estimated number of hospitalizations, 96% had HA as the primary diagnosis. The hospitalization rate decreased from 1.06 per 100 000 person-years between 1990 and 1997 to 0.36 between 1998 and 2003. During the study period, 54% HA hospitalizations were in 20–39 year-olds. The overall case fatality ratio among hospitalized patients was 1.4%, increasing from 0.4% in those Conclusion HA hospitalization rates have been low since 1998 but the cause of this is unclear given the cyclical pattern of HA. Travel to endemic countries remains the most important risk factor and improved control of HA will require better strategies to vaccinate travelers.

  1. The scientific and technical committee on the management of dams in Quebec, Canada

    International Nuclear Information System (INIS)

    A Committee of Inquiry, consisting of members of the Canadian Dam Safety Association, was set up by the Government of Quebec following the Saguenay-Lac Saint Jean disaster in July 1996. The report of the Scientific and Technical Committee was published in two volumes. In this English language version Volume 1 contains the report of the Committee, including its conclusions and recommendations on how the management of dams might be improved in the future. Volume 2 contains a series of appendices, mostly of technical data, the report of the Advisory Board and a summary of public hearings held by the Committee. In the course of the Committee's investigation, the basins and physical characteristics of the watersheds that were most heavily impacted were subjected to intense examination. An examination of the existing framework and regulations for the management of the structures, and a thorough evaluation of the structures themselves, were also part of the inquiry. It was concluded that the flood was an exceptional phenomenon, one that the existing infrastructure and services were never built to resist. The inquiry also reviewed existing infrastructure codes adopted by the Ministry of Transportation, and probed the responsibilities of the government, the owners, and the regional and municipal authorities. Finally, the committee provided a series of recommendations for a much stricter framework for the design, surveillance and management of water retaining works, designed to prevent recurrence of the 1996 disaster. tabs., figs

  2. The 'common knowledge' of Quebecers: quantifying the evidence of historians testifying for defendant tobacco companies.

    The 'common knowledge' defence is a legal strategy which has been successfully used by defendant tobacco companies to avoid legal responsibility for the harms caused by smoking. Tobacco companies have hired professional historians to try to persuade courts about a longstanding high level of public awareness regarding the risks of tobacco use. To support this argument, they have used archival news clippings and media reports. Two historians were hired by tobacco companies to offer this defence during a recent class action trial in Canada, following which they were required to submit to the court the collection of media materials which had been gathered by history students to assist their testimony. Included in this collection were tobacco advertisements and other news items about tobacco products which the students had inadvertently also collected. Quantifying this collection reveals that even by the tobacco industry's own construct, the information environment surrounding Quebec smokers in the middle 20th century included more prosmoking messages than information about the risks of smoking.

    The 11q21-22 region is of interest for schizophrenia because several candidate genes are located in this section of the genome. The 11q21-22 region, including DRD2, was surveyed by linkage analysis in a sample (N = 242) made of four large multigenerational pedigrees densely affected by schizophrenia (SZ) and eight others by bipolar disorder (BP). These pedigrees were ascertained in a large area of Eastern Quebec and Northern New Brunswick and are still being extended. Family members were administered a {open_quotes}consensus best-estimate diagnosis procedure{close_quotes} (DSM-III-R criteria) blind to probands and relatives` diagnosis and to pedigree assignment (SZ or BP). For linkage analysis, 11 microsatellite polymorphism (CA repeat) markers, located at 11q21-22, and comprising DRD2, were genotyped. Results show no evidence of a major gene for schizophrenia. However, a maximum lod score of 3.41 at the D11S35 locus was observed in an affected-only analysis of one large SZ family, pedigree 255. Whether or not the positive linkage trend in pedigree 255 reflects a true linkage for a small proportion of SZ needs to be confirmed through the extension of this kindred and through replication. 36 refs., 2 tabs.

    Saproxylic succession in fire-killed black spruce [Picea mariana (Mill.) B.S.P.] coarse woody debris (CWD) in northern Quebec is estimated in this study using a 29-yr postfire chronosequence. Sampling was performed using both trunk-window traps and rearing from snag and log sections. A total of 37,312 arthropods (>220 taxa) were collected from both sampling methods. Two distinct colonization waves were identified. The onset of initial colonization occurs the year of the fire, whereas the second colonization phase begins only once debris falls to the ground. The initial colonization step is influenced by fire-associated species including subcortical predators, xylophages, and ascomycetes feeders. Abundance of most early colonizer species decline with time since fire with the disappearance of subcortical habitat. No noticeable species turnover occurred in snags thereafter. Lack of succession in snags is related to very low decomposition rates for postfire CWD because this substrate is unsuitable for species associated with highly decayed wood. Snag falling triggers fungal growth and concomitant saproxylic succession toward micro- and saprophagous species and increases accessibility for soil-dwelling organisms. Because the position of woody debris greatly influences overall physical properties of dead wood, the fall of burned CWD plays a major role in saproxylic community shift after fire. PMID:17349126

    Stable colonization of the Gaspe Peninsula by Europeans started in the middle of the 18th century at the time of the British conquest of New France. The earliest settlers were Acadians, escaping British deportation policies, followed by Loyalists from the US, who preferred to remain under British rule after the Declaration of Independence. In the 19th century, the developing fishing industry attracted French Canadians from the St. Lawrence Valley and newcomers from Europe including Channel Islanders from Jersey and Guernsey. We analyzed parental lineages of the self-declared descendants of these four groups of settlers by mtDNA D-loop sequencing and Y-chromosome genotyping and compared them with French, British, and Irish samples. Their representation in terms of haplotype frequency classes reveals different signatures of founder effects, such as a loss of rare haplotypes, modification of intermediate frequency haplotypes, reduction in genetic diversity (seen in Acadians), but also enrichment by admixture. Parental lineages correlate with group identity. Descendants of early settlers, Acadians and Loyalists, preserved their identity more than those of French Canadian and Channel Islander "latecomers." Although overall genetic diversity among Gaspesians is comparable with their European source populations, F(ST) analysis indicated their greater differentiation. Distinct settlement history, a limited number of founders and relative genetic isolation contributed to the regionalization of the Quebec gene pool that appears less homogenous than usually anticipated.

    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.

    Declining lake levels (Aral Sea syndrome) can be caused by changes in climate, increased water use or changed regulation patterns. This paper introduces a novel lake geometry index (LGI) to quantify lake hydrological characteristics. The index was developed using a large representative dataset of lake hypsographic characteristics from 152 lakes and man-made reservoirs. Using the LGI index, lakes can be classified into five groups: groups 1-4 when LGI is 0.5-2.5, 2.5-4.5, 4.5-6.5 and 6.5-8.5, respectively, and group 5 when LGI is >8.5. Naturally shallow and vast lakes and wetlands fall into the first group and deep man-made reservoirs in narrow valleys are in group 5. The response of three different lake systems (LGI 0.75, 2.75 and 6.5) to different water flow scenarios was then simulated using the water balance equation. From this, the index 'potential lake area' (Apot) was developed to show lake responses to changed hydro-climatological conditions. Apot and LGI can be used to classify lakes into open or closed systems. Simulations showed that lakes with low LGI have a shorter response time to flow and climate changes. As a result, the impact of water balance restoration is faster for lakes with low LGI than for lakes with high LGI. The latter are also more vulnerable to climate variation and change.

    Full Text Available Este artigo traz uma análise comparativa Canadá/Quebec de interrelações: de um lado, três modelos de regulação da educação (a burocracia estatal, a profissão e o mercado; e, de outro, a autonomia profissional dos professores. A noção de autonomia profissional dos professores, tal como é veiculada pelas associações profissionais e sindicatos canadenses e quebequenses, permite analisar a evolução desses modos de regulação. Adotando um ponto de vista neo-institucionalista, o artigo mostra que a autonomia profissional reivindicada ou defendida pelos professores como por suas associações sindicais repousa mais sobre as atividades percebidas como centrais por esses atores que sobre aquelas ditas periféricas. Isto permite compreender a força da reação no restante do Canadá contra a centralização do currículo e a padronização da avaliação da aprendizagem e a relativa acomodação dos professores quebequenses à participação nos conselhos escolares e na participação dos pais. Nesses dois contextos, entretanto, constatamos uma resistência à reorganização do trabalho dos professores.The paper deals with the relationships between models of regulation (bureaucratic, professionnal and market of education and teacher autonomy. As espoused by professional and labour associations of Canada and Quebec, teacher autonomy is used to disclose the evolution of models of educational regulation. Adopting a neo-institutionalist point of view, the paper argues that teacher autonomy, as promoted by canadian teacher unions, refers to activities considered central of teachers' work, as opposed to peripheral activities. This distinction helps understand why in Canada a strong reaction against curriculum centralization and standardization of evaluation has been observed, whereas Quebec teachers' unions seem to accommodate themselves with an increase in parental power.

  7. Resilience and Restoration of Lakes

    Directory of Open Access Journals (Sweden)

    Kathryn L. Cottingham

    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.

  8. Myotonic dystrophy in Quebec: geographical distribution and concept of genetic homogeneity.

    Laberge, C

    1989-02-01

    The geographical distribution relative to place of residence of patients with myotonic dystrophy (MD) and admitted to a Quebec hospital during a five year period (1980-1984) is presented and discussed. The sample consists of 72 males and 68 females of varying ages over 10 years. Analysis of the data shows a North Shore distribution of patients in a cline from Saguenay-Lac-St-Jean, through Québec City and to Montréal. However, a low prevalence is apparent on the South Shore, east of Québec City, for which an historical and genealogical explanation are discussed. This geographic distribution favours the hypothesis of genetic homogeneity for the MD gene in the Québec population. A stronger second argument comes from genealogical studies of 10 families sampled from the Chicoutimi Muscular Dystrophy Clinic. Genealogical paths traced to ancestors who founded Charlevoix for these 10 families go back to a cluster of 25 founders, one of whom must have been the carrier of the MD gene. The probative third argument for genetic homogeneity comes from the allelic distribution of the apolipoprotein E (ApoE) gene in the Québec City, Saguenay and in families with MD. The ApoE locus is on chromosome 19 and closely linked to MD. In MD-affected individuals there is a linkage disequilibrium for the epsilon 4 allele while non-MD members of these families show allelic frequencies not differing significantly from the control population.(ABSTRACT TRUNCATED AT 250 WORDS)

  9. Strategies for the development of Quebec's petrochemical industry: education and environment

    International Nuclear Information System (INIS)

    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

    Abstract Background: In Quebec, women living on low income receive a number of additional prenatal care visits, determined by their area of residence, of both multi-component and food supplementation programs. We investigated whether increasing the number of visits reduces the odds of the main outcome of small for gestational age (SGA) birth (weight general population were deduced from data on multi-component and food supplement interventions, the Canadian census and the Canadian Community Health Survey. Mothers without a high school diploma were eligible for the programs. Multilevel logistic regression models were fitted using generalized estimating equations to account for the correlation between individuals on the same territory. Potential confounders included sedentary behaviour and cigarette smoking. The odds ratios (ORs) were adjusted for mother’s age, marital status, parity, program coverage and mean income in the area. Results: Mothers eligible for the programs remain at a higher odds of SGA than non-eligible mothers (OR =  1.40; 95% confidence interval [CI]: 1.30–1.51). Further, areas that provide more visits to eligible mothers (4–6 food supplementation visits) seem more successful at reducing the frequency of SGA birth than those that provide 1–2 or 3 visits (OR  =  0.86; 95% CI: 0.75–0.99). Conclusions: Further studies that validate whether an increase in the number of prenatal care interventions reduces the odds of SGA birth in different populations and evaluate other potential benefits for the children should be done.

    The increasing number of studies on the determination of natural methane in groundwater of shale gas prospection areas offers a unique opportunity for refining the quantification of natural methane emissions. Here methane emissions, computed from four potential sources, are reported for an area of ca. 16,500km(2) of the St. Lawrence Lowlands, Quebec (Canada), where Utica shales are targeted by the petroleum industry. Methane emissions can be caused by 1) groundwater degassing as a result of groundwater abstraction for domestic and municipal uses; 2) groundwater discharge along rivers; 3) migration to the surface by (macro- and micro-) diffuse seepage; 4) degassing of hydraulic fracturing fluids during first phases of drilling. Methane emissions related to groundwater discharge to rivers (2.47×10(-4) to 9.35×10(-3)Tgyr(-1)) surpass those of diffuse seepage (4.13×10(-6) to 7.14×10(-5)Tgyr(-1)) and groundwater abstraction (6.35×10(-6) to 2.49×10(-4)Tgyr(-1)). The methane emission from the degassing of flowback waters during drilling of the Utica shale over a 10- to 20-year horizon is estimated from 2.55×10(-3) to 1.62×10(-2)Tgyr(-1). These emissions are from one third to sixty-six times the methane emissions from groundwater discharge to rivers. This study shows that different methane emission sources need to be considered in environmental assessments of methane exploitation projects to better understand their impacts.

    Full Text Available Abstract Background Abundant literature supports the beneficial effects of physical activity for improving health of people with chronic diseases. The relationship between multimorbidity and physical activity levels, however, has been little evaluated. The purpose of the current exploratory study was to examine the relationship between a multimorbidity and physical activity levels, and b long-term limitations on activity, self-rated general health, psychological distress, and physical activity levels for each sex in adults, after age, education, income, and employment factors were controlled for. Methods Data from the Quebec Health Survey 1998 were used. The sample included 16,782 adults 18–69 yr of age. Independent variables were multimorbidity, long-term limitations on activity, self-rated general health, and psychological distress. The dependent variable was physical activity levels. Links between the independent and dependent variables were assessed separately for men and women with multinomial regressions while accounting for the survey sampling design and household clustering. Results About 46% of the participants were men. Multimorbidity was not associated with physical activity levels for either men or women. Men and women with long-term limitations on activity and with poor-to-average self-rated general health were less likely to be physically active. No relationship between psychological distress and physical activity was found for men. Women with high levels of psychological distress were less likely to be physically active. Conclusion Multimorbidity was not associated with physical activity levels in either sex, when age, education, income, and employment factors were controlled for. Long-term limitations on activity and poor-to-average self-rated general health seem related to a reduction in physical activity levels for both sexes, whereas psychological distress was associated with a reduction in physical activity levels only

  13. Black spruce growth forms as a record of a changing winter environment at treeline, Quebec, Canada

    International Nuclear Information System (INIS)

    The environmental conditions prevailing at treeline in subarctic Quebec have been reconstructed over the past 400 yr through a comparative analysis of tree rings and growth forms of black spruce (Picea mariana [Mill.] B.S.P.). Because black spruce growth forms are closely associated with the winter environment, they are a direct response to conditions of low temperature and windblown snow abrasion affecting living tissues at the snow-air interface. The age structure of supranival shoot populations was closely associated with periods of higher stem survival in winter most likely under snowier and windless conditions. Spruce growth on slopes and in the valley revealed periods of low tree-ring growth between 1601 and 1663 and between 1700 and 1904, respectively. A long-lasting period of low radial growth 1697 and 1939 prevailed in the hilltop site. During the 20th century, spruce height increased from 0.8 to 1.6 m on slopes and in the valley, while the basal level of abrasion from windblown snow increased from 0.1 to 0.5 m, suggesting an increasing trend towards warmer and snowier conditions. Abraded spruces growing during the Little Ice Age (1570-1880) were replaced by symmetrical trees during the 20th century. Supranival skirted and whorled spruces which dominated on the hilltop site during the 16th century reverted to infranival cushion and mat growth forms during the Little Ice Age. These stunted spruces were unable to recover during the recent warming because of their inability to catch enough drifting snow to allow vertical growth

  14. Monitoring CO2 Sequestration by Mineral Carbonation in Mine Tailings at Thetford Mines, Quebec, Canada

    Mineral carbonation is considered a permanent option to capture and store atmospheric CO2. This reaction occurs naturally under ambient conditions in ultramafic mining and milling waste. In the region of Thetford Mines, Quebec, chrysotile mining has produced approximately 0.8 Gt of magnesium-rich milling waste, which mainly consists of poorly sorted ultramafic rock fragments (soil temperature, volumetric water content, gas pressure and gas composition, with ambient conditions recorded by an autonomous meteorological station. The cells were monitored for water geochemistry, carbon content and mineralogy, with the objective to better understand the mineral carbonation processes under natural conditions and to propose a conceptual model for mineral carbonation at the pilot scale. To validate this model, numerical simulations with the MIN3P reactive transport code have been carried out. The chemical composition of the cell leachate (pH > 10, Mg from 85 to 140 mg.L-1, and high total alkalinity from 260 to 300 mg.L-1 CaCO3) is consistent with active CO2 mineralization reactions within the cell. SEM analyses show precipitation of dypingite with a lamellar texture and cemented grain surfaces. The milling waste contains up to 1.2% C, which indicates CO2 sequestration by mineral carbonation. Measured CO2 concentrations in the interstitial air are also ten times lower than in the atmosphere. Analysis of seasonal variations in fluid flow and heat transfer (essentially by thermal conduction) shows that molecular diffusion is the main process for CO2 supply within the experimental cells. These observations have helped develop a conceptual model for mineral carbonation in the wastes and were used to calibrate the reactive transport model.

  15. Is Lake Chabot Eutrophic?

    Science.gov (United States)

    Pellegrini, K.; Logan, J.; Esterlis, P.; Lew, A.; Nguyen, M.

    2013-12-01

    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

  16. Proceedings of the 65. conference of the Ordre des agronomes du Quebec : Effects of climate change on agriculture and agri-food sectors : local solutions

    International Nuclear Information System (INIS)

    This conference provided a forum for the exchange of scientific knowledge concerning new management tools and agricultural practices that will ensure sustainable development in the agriculture and agri-food sectors in Quebec in light of climate change. Agricultural practices were examined in an effort to see how greenhouse gas (GHG) emissions can be reduced. A review of the knowledge accumulated to date on climate change was presented along with a look at the impact of greenhouse gas emissions on Quebec's agricultural sector. Climate and the greenhouse effect were discussed, with particular emphasis on a European perspective of the agricultural sector. Nine presenters also participated in 3 smaller conferences on specific themes which examined GHG sources and methods to reduce emissions in animal and plant production. The impacts of climate change and adaptation methods in Quebec were discussed. Twelve of the 13 papers were indexed separately for inclusion in this database

  17. Hydraulic properties and scale effects investigation in regional rock aquifers, south-western Quebec, Canada

    Nastev, M.; Savard, M. M.; Lapcevic, P.; Lefebvre, R.; Martel, R.

    This paper reports on the characterization of hydraulic properties of regional rock aquifers carried out within a groundwater resources assessment project in the St. Lawrence Lowlands of south-western Quebec. To understand the aquifer behavior at both the fracture level and at field scale, hydraulic investigations were carried out using various aquifer tests. The groundwater flow at the local scale is controlled mostly by the fracture system. Results of the constant-head injection tests show a weak decreasing trend of hydraulic conductivity with depth indicating that a major part of the groundwater flow occurs in the first meters of the rock sequence. At the regional scale, the equivalent porous media approach is applicable. The hydraulic conductivity measurements were correlated to the scale of the aquifer tests expressed with the investigated aquifer volume. A simple interpolation procedure for the hydraulic conductivity field was developed based on the distance between field measurements and the tested aquifer volumes. The regional distribution of the hydraulic conductivity for the major fractured aquifer units indicates that dolostone is the most permeable whereas sandstone and crystalline rocks are the least permeable units. Este artículo trata de la caracterización de las propiedades hidráulicas en acuíferos regionales rocosos, la cual se llevó a cabo dentro del proyecto de evaluación de los recursos de agua subterránea en St. Lawrence Lowlands al suroeste de Quebec. Para entender el comportamiento del acuífero tanto a nivel de fractura como a escala del campo, se ejecutaron investigaciones hidráulicas usando varias pruebas de acuífero. El flujo del agua subterránea a escala local está controlado principalmente por el sistema de fracturas. Los resultados de las pruebas de inyección con cabeza constante muestran una tendencia decreciente débil de la conductividad hidráulica con la profundidad, indicando que la mayor parte del flujo de agua

    Crosman, Erik T.; Horel, John D.

    2016-05-01

    Case studies of lake breezes during wintertime cold air pools in Utah's Salt Lake Valley are examined. While summer breezes originating from the Great Salt Lake are typically deeper, of longer duration, and have higher wind speeds than winter breezes, the rate of inland penetration and cross-frontal temperature differences can be higher during the winter. The characteristics of winter breezes and the forcing mechanisms controlling them (e.g., snow cover, background flow, vertical stability profile, clouds, lake temperature, lake sheltering, and drainage pooling) are more complex and variable than those evident in summer. During the afternoon in the Salt Lake Valley, these lake breezes can lead to elevated pollution levels due to the transport of fine particle pollutants from over the Great Salt Lake, decreased vertical mixing depth, and increased vertical stability.

  4. Mono Lake Excursion Reviewed

    Science.gov (United States)

    Liddicoat, J. C.; Coe, R. S.

    2007-05-01

    The Mono Lake Excursion as recorded in the Mono Basin, CA, has an older part that is about negative 30 degrees inclination and about 300 degrees declination during low relative field intensity. Those paleomagnetic directions are closely followed by greater than 80 degrees positive inclination and east declination of about 100 degrees during higher relative field intensity. A path of the Virtual Geomagnetic Poles (VGPs) for the older part followed from old to young forms a large clockwise loop that reaches 35 degrees N latitude and is centered at about 35 degrees E longitude. That loop is followed by a smaller one that is counterclockwise and centered at about 70 degrees N latitude and 270 degrees E longitude (Denham & Cox, 1971; Denham, 1974; Liddicoat & Coe, 1979). The Mono Lake Excursion outside the Mono Basin in western North America is recorded as nearly the full excursion at Summer Lake, OR (Negrini et al., 1984), and as the younger portion of steep positive inclination/east declination in the Lahontan Basin, NV. The overall relative field intensity during the Mono Lake Excursion in the Lahontan Basin mirrors very closely the relative field intensity in the Mono Basin (Liddicoat, 1992, 1996; Coe & Liddicoat, 1994). Using 14C and 40Ar/39Ar dates (Kent et al., 2002) and paleoclimate and relative paleointensity records (Zimmerman et al., 2006) for the Mono Lake Excursion in the Mono Basin, it has been proposed that the Mono Lake Excursion might be older than originally believed and instead be the Laschamp Excursion at about 40,000 yrs B.P. (Guillou et al., 2004). On the contrary, we favor a younger age for the Mono Lake Excursion, about 32,000 yrs B.P., using the relative paleointensity in the Mono Basin and Lahontan Basin and 14C dates from the Lahontan Basin (Benson et al., 2002). The age of about 32,000 yrs B.P. is also in accord with the age (32,000- 34,000 yrs B.P.) reported by Channell (2006) for the Mono Lake Excursion at ODP Site 919 in the Irminger Basin

    Despite vaccination, cyclical peaks of Bordetella pertussis incidence rates are still observed in Canada and other developed countries, making pertussis one of the most prevalent vaccine preventable bacterial diseases. In the postacellular vaccine era, evolution of bacterial strains has resulted in strains with altered vaccine antigens. Previous Canadian studies have focused on isolates mainly from the provinces of Ontario and Alberta, with only small numbers of isolates from other provinces. Therefore, in this study, we examined a larger sample (n = 52) of isolates from Quebec, Canada, between 2002 and 2014. Isolates were characterized by serotype, sequence type, and prevalence of pertactin deficiency. The Quebec isolates shared characteristics similar to other Canadian isolates and to isolates circulating globally. Although pertactin-deficient isolates were not present, a significant shift in sequence type was observed in more recent years. This study highlights the importance of continually monitoring disease-causing isolates to track evolutionary trends and gain a better understanding of the molecular epidemiology of pertussis in Canada.

    People living with HIV (PWHIV) face negative attitudes that isolate and discourage them from accessing services. Understanding negative attitudes and the social environment can lead to more effective health promotion strategies and programs. However, a scale to measure attitudes has been lacking. We developed and validated attitudes toward PWHIV Scale to examine trends in attitudes toward PWHIV in Quebec in 1996, 2002, and 2010. We also examined the relationship between negative attitudes toward PWHIV, homophobia, and knowledge about HIV transmission. The scale included 16 items and had a five-factor structure: F1 (fear of being infected), F2 (fear of contact with PWHIV), F3 (prejudicial beliefs toward groups at high risk of HIV), F4 (tolerance regarding sexual mores and behaviors), and F5 (social support for PWHIV). The validity and reliability of the scale were assessed and found to be high. Overall, Quebecers had positive attitudes toward PWHIV, with more negative attitudes observed in subgroups defined as male, ≥50 years of age, homophobia, and below-average knowledge about HIV transmission. Scores were stable between 1996 and 2002, and increased in 2010. Negative attitudes were correlated with higher levels of homophobia and lesser knowledge about HIV transmission. The lowest scores for each factor were observed in the same subgroups that had low overall scores on the Attitudes Scale. The findings from this study can be used to intensify interventions that promote compassion for PWHIV, address attitudes toward homosexuality, and encourage greater knowledge about the transmission of HIV in these subgroups.

  8. Baseline scenario for gas, odor, dust and particulate matter emissions from swine buildings in Quebec : part 1 : emissions inventory

    International Nuclear Information System (INIS)

    The livestock industry, particularly the swine sector, has taken measures to minimize the environmental impacts of meat production at both the local, regional and global scale. This paper reported on solutions to reduce emissions associated with animal production through animal waste management. The substances targeted by technological improvements for swine barns include carbon dioxide, methane, nitrous oxide, ammonia, dust, odors and particulate matters. Stakeholders in Quebec's swine sector have taken the initiative to evaluate and compare the environmental performances of various in-barn technologies and practices. This paper also presented a project aimed at defining baseline scenarios for gaseous wastes, odor, dust and particulate matter emissions from pig barns, using 2006 as the reference year. The study considered all stages of production of a typical farrow-to-finish farm in Quebec. The paper outlined a methodology based on emissions inventory in order to define this baseline scenario. The results and key limitations of this methodology were discussed. 26 refs., 5 tabs., 1 appendix.

    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. PMID:27104923

    Introduction Trans youths are more likely to experience negative social and parental reactions suggesting reprehension, from disapproving looks to physical violence. While victimization increases the likelihood of poor mental health outcomes, little is known about potential mediating factors between mental health and victimization. Self-esteem is one of the factors that may mediate the impact of homophobic victimization on mental health. Yet, data on trans youths are scarce.Objectives The objectives of this paper are: 1) to compare trans youths to cisgender heterosexual male and female youths regarding two different forms of victimization (victimization based on gender nonconformity and parental verbal abuse), self-esteem, and psychological distress, as well as 2) to test a path model of the impact of these two forms of victimization on self-esteem and psychological distress.Methods Data for this study are drawn from the Quebec Youths' Romantic Relationships survey. Data were collected among youth aged 14 to 22 years old recruited either in schools or online. Thirty-seven participants endorsed being trans or questioning their gender identity. They were paired to 74 cisgender heterosexual youths (37 male and 37 female) using propensity scores based on socio-demographic characteristics.Results Results showed that verbal parental abuse and victimization based on gender nonconformity were more prevalent among trans participants. Parental verbal abuse and victimization based on gender nonconformity were both directly and negatively associated with self-esteem (explained variance: 36%). Sexual status explains 19.6% of the variance of parental victimization and 50.6% of the variance of victimization on the basis of gender nonconformity. A higher self-esteem was associated with decreased psychological distress (explained variance: 66.9%). Moreover, parental verbal abuse was also directly associated with higher psychological distress. Although there was no direct

    Full Text Available Abstract Background The quality of the relationship with the spouse/partner appears crucial among patients with multiple chronic conditions where illness management is complex and multifaceted. This study draws on data from the Quebec Health Survey (QHS to examine, among patients with one or more chronic conditions, the relation between marital status, the perceived conflict with the spouse/partner, and what the patients do to manage their illness as well as how they perceive their health. Methods Data from the QHS 1998 were used. The sample included 7547 coupled adults who had one or more chronic health problems lasting more than 6 months. Independent variables included marital status, perceived conflict with the spouse/partner, and the number of chronic conditions. Illness management was defined broadly as a measure of the patient's efforts at self-care and an illness status indicator, including visits to the generalist and the specialist, the use of telephone health line in the last 12 months, self-rated general health, mental health, and a measure of psychological distress. Linkages between the independent variables and illness management were assessed for males and females separately with logistic regressions, while accounting for the survey sampling design and household clustering. Results Female patients who did not live with their partner and had never been married were more likely to report a negative perception of their general health and a higher psychological distress than those who were married. Perceived conflict with the partner was linked to a negative perception of mental health and a higher psychological distress among both men and women. Compared to patients with only one chronic condition, males who reported more than one chronic condition were more likely to have consulted a generalist prior to the survey and used the telephone health line, whereas females were more likely to have consulted a specialist. Both males and

    International Nuclear Information System (INIS)

    Bottom and sestonic sediments of Ypacarai Lake were investigated with XRF and Moessbauer techniques. The 120 km2 lake, depth averages 1.8 m. In addition to the lakes use for recreation, its basin has economic significance. Sediments play an important role in the distribution of trace elements in the aquatic system and as a sink for metals. Bottom and seston samples were taken from 4 different sampling stations which were selected according the morphology and population sites on the shore. The concentration of toxic metals was found to be low and no adverse ecological impact should be expected. The main metallic ion component is iron (1.68%). Moessbauer studies showed this element appears as Fe3+. Iron2+ was not detected. We suggest that Fe3+ acts as the limiting element which controls the eutrophication process.

    Full Text Available Dojran Lake with its hydrological basin is a closed hydrologicalsystem with natural inflow of water to the lake, but no natural outflow. Rechargeof the lake is from direct surface and underground inflow. Within the period 1950-1960 the lake faced with extremely high water level that was not favorable for thedevelopment of fishing. It was built an artificial channel to regulate the water levelin the lake and control the water use at Greek side of the lake. In the period 1988-2000, the water level in the lake continuously was declining. Water leveldeclination caused ecological catastrophe for the flora and fauna in the lake andlake’s basin that was inconvenience for the basic economy in the region, tourismand fishing. The reasons for declining the water level in the lake are not clearlyidentified, and they are located in unfavorable hydrological conditions expressedthrough longer dried period or uncontrolled usage the water from the lake.In 2002, the Republic of Macedonia finished a project to build a system forbringing water from Gjavato wells near Vardar River with capacity of 1 m3/s. Thewater level in the lake has recently increased. In order to define the causes ofchanges in the lake requires detailed hydrological and meteorological analysis.This paper will present the results of hydrological and meteorological analysis onthe basis of historical data of measured water level, precipitation, and airtemperature from hydrometeorological station New Dojran for the period 1961-2008.

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

    International Nuclear Information System (INIS)

    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

    On Earth, lakes provide favorable environments for the development of life and its preservation as fossils. They are extremely sensitive to climate fluctuations and to conditions within their watersheds. As such, lakes are unique markers of the impact of environmental changes. Past and current missions have now demonstrated that water once flowed at the surface of Mars early in its history. Evidence of ancient ponding has been uncovered at scales ranging from a few kilometers to possibly that of the Arctic ocean. Whether life existed on Mars is still unknown; upcoming missions may find critic

    Full Text Available Lakes are suffering from different stress factors and need to be restored using different approaches. The eutrophication remains as the main water quality management problem for inland waters: both lakes and reservoirs. The way to curb the degradation is to stop the nutrient sources and to accelerate the restoration with help of in-lake technologies. Especially lakes with a long retention time need (eco- technological help to decrease the nutrient content in the free water. The microbial and other organic matter from sewage and other autochthonous biomasses, causes oxygen depletion, which has many adverse effects. In less developed countries big reservoirs function as sewage treatment plants. Natural aeration solves problems only partly and many pollutants tend to accumulate in the sediments. The acidification by acid rain and by pyrite oxidation has to be controlled by acid neutralizing technologies. Addition of alkaline chemicals is useful only for soft waters, and technologies for (microbial alkalinization of very acidic hardwater mining lakes are in development. The corrective measures differ from those in use for eutrophication control. The salinization and water shortage mostly occurs if more water is used than available. L. Aral, L. Tschad, the Dead Sea or L. Nasser belong to waters with most severe environmental problems on a global scale. Their hydrologic regime needs to be evaluated. The inflow of salt water at the bottom of some mining lakes adds to stability of stratification, and thus accumulation of hydrogen sulphide in the monimolimnion of the meromictic lakes. Destratification, which is the most used technology, is only restricted applicable because of the dangerous concentrations of the byproducts of biological degradation. The contamination of lakes with hazardous substances from industry and agriculture require different restoration technologies, including subhydric isolation and storage, addition of nutrients for better self

  7. Reevaluation of lake trout and lake whitefish bioenergetics models

    2013-01-01

    Using a corrected algorithm for balancing the energy budget, we reevaluated the Wisconsin bioenergetics model for lake trout (Salvelinus namaycush) in the laboratory and for lake whitefish (Coregonus clupeaformis) in the laboratory and in the field. For lake trout, results showed that the bioenergetics model slightly overestimated food consumption by the lake trout when they were fed low and intermediate rations, whereas the model predicted food consumption by lake trout fed ad libitum without any detectable bias. The slight bias in model predictions for lake trout on restricted rations may have been an artifact of the feeding schedule for these fish, and we would therefore recommend application of the Wisconsin lake trout bioenergetics model to lake trout populations in the field without any revisions to the model. Use of the Wisconsin bioenergetics model for coregonids resulted in overestimation of food consumption by lake whitefish both in the laboratory and in the field by between 20 and 30%, on average. This overestimation of food consumption was most likely due to overestimation of respiration rate. We therefore adjusted the respiration component of the bioenergetics model to obtain a good fit to the observed consumption in our laboratory tanks. The adjusted model predicted the consumption in the laboratory and the field without any detectable bias. Until a detailed lake whitefish respiration study can be conducted, we recommend application of our adjusted version of the Wisconsin generalized coregonid bioenergetics model to lake whitefish populations in the field.

    Long-term temperature trends in lakes integrate hydrological and meteorological factors. We examine temperature trends in a small montane lake with prolonged ice-cover and large seasonal snowfall and in a large saline lake. Emerald Lake, located in the Sierra Nevada (California), is representative of high-elevation lakes throughout the region. No significant trend in outflow temperature was apparent from 1991to 2012. Snowfall in the watershed accounted for 93% of the variability in average summer lake temperatures. Mono Lake (California) lies in a closed, montane basin and is hypersaline and monomictic or meromictic. Temperature profiles have been collected from 1982 to 2010. In the upper water column, the July-August-September water temperatures increased 0.8-1.0°C over the 29 years. This rate of warming is less than published estimates based on satellite-derived skin temperatures and will discussed in the context of general limnological interpretation of temperature trends.

    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{sup 3}LS) are emerging worldwide. In Quebec, Canada, a Task Force was mandated by NanoQuebec to conceive a Ne{sup 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{sup 3}LS. Their resulting action plan, made public in November 2006, contained several recommendations, including the creation of a knowledge network (Ne{sup 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{sup 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{sup 3}LS research activities (grants and fellowships); 2) Spearhead the Canadian and international Ne{sup 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.

  2. An at-site flood estimation method in the context of nonstationarity II. Statistical analysis of floods in Quebec

    Gado, Tamer A.; Nguyen, Van-Thanh-Van

    2016-04-01

    This paper, the second of a two-part paper, investigates the nonstationary behaviour of flood peaks in Quebec (Canada) by analyzing the annual maximum flow series (AMS) available for the common 1966-2001 period from a network of 32 watersheds. Temporal trends in the mean of flood peaks were examined by the nonparametric Mann-Kendall test. The significance of the detected trends over the whole province is also assessed by a bootstrap test that preserves the cross-correlation structure of the network. Furthermore, The LM-NS method (introduced in the first part) is used to parametrically model the AMS, investigating its applicability to real data, to account for temporal trends in the moments of the time series. In this study two probability distributions (GEV & Gumbel) were selected to model four different types of time-varying moments of the historical time series considered, comprising eight competing models. The selected models are: two stationary models (GEV0 & Gumbel0), two nonstationary models in the mean as a linear function of time (GEV1 & Gumbel1), two nonstationary models in the mean as a parabolic function of time (GEV2 & Gumbel2), and two nonstationary models in the mean and the log standard deviation as linear functions of time (GEV11 & Gumbel11). The eight models were applied to flood data available for each watershed and their performance was compared to identify the best model for each location. The comparative methodology involves two phases: (1) a descriptive ability based on likelihood-based optimality criteria such as the Bayesian Information Criterion (BIC) and the deviance statistic; and (2) a predictive ability based on the residual bootstrap. According to the Mann-Kendall test and the LM-NS method, a quarter of the analyzed stations show significant trends in the AMS. All of the significant trends are negative, indicating decreasing flood magnitudes in Quebec. It was found that the LM-NS method could provide accurate flood estimates in the

    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.

  4. New insights on the late-stage history of glacial Lake Ojibway: implications for meltwater discharges of the last deglaciation

    Science.gov (United States)

    2016-04-01

    The decay of the Laurentide ice sheet is believed to be responsible for abrupt climate variations during the last deglaciation and early Holocene, notably through massive discharges of meltwater that had accumulated in large ice-dammed lakes such as Lake Agassiz and Lake Ojibway. Indeed, high-resolution North Atlantic marine records indicate that the ocean's circulation was affected by several outbursts of meltwater during the late deglacial interval. Yet, field evidence and geological data supporting multi-step drawdowns of Lake Agassiz-Ojibway are relatively limited, underlying important uncertainties in the late-stage history of these glacial lakes. Furthermore, physical evidence for the drainage of glacial lakes remains relatively rare in depositional records, giving rise to much debate on the location of outlets and discharge pathways, as well as on the climate impact of the attendant meltwater forcing. Recent investigations of geomorphological and sedimentary records in northern Ontario and Quebec (Canada) have revealed new insights on the late-stage evolution of Lake Ojibway. The number of Ojibway lake phases have so far remained poorly documented mainly because of the dominance of fine-grained glaciolacustrine sediments in the lake basin that prevented the formation of extensive sandy/bouldery strandlines. We thus developed an alternative approach based on the study of a complex sequence of relict terraces carved in the Ojibway clay plain. The elevation measurement of 154 raised wave-cut scarps provided evidence for four distinct shorelines, three of which projecting well below the main outlet that controlled the elevation of the lake during the deglaciation. The elevation, uplift gradients, and areal extent of these shorelines indicate that these low-elevation lake levels formed during the late stages of the deglaciation, following abrupt drawdowns of the lake's surface. Insights on the origin of these late-stage phases are provided from sediment sequences

It is noted that the terms are highly related by definition and that a clear similarity exists. Accordingly, a prospective look is taken at the challenges involved in the understanding and application of psychological harassment based on seven dimensions commonly studied and referred to in the academic literature on emotional abuse. The conclusion is that the determination of psychological harassment involves a multidimensional consideration of factors and that this gives rise to several challenges in applying the new legislation.Cet article s’intéresse au concept d’abus émotif au travail et à son application à des problèmes de harcèlement psychologique, tel que défini par la législation promulguée au Québec en juin 2004.

    Astalos, Monique

    This study examines a view of nature in primary science education at the international level. Currently, in international studies of science programs, this aspect has been rarely considered. A better knowledge of science textbooks would give one a better understanding of the cultural variations between countries, and, would bring more precision to the cultural contexts. The study analyzes a view of nature, particularly the relationships between man and animal found in primary science textbooks in Quebec, France and Senegal. One needs to discern if there are any differences between these countries. The assumptions are based on the primary science textbooks view of nature that essentially takes an anthropocentric view, but with some variations between cultures. This research is primarily exploratory since this phenomena has been studied only minimally. The problem is examined within each country. The types of relationships between man and animal have been identified and the textbooks have been compared with each other. Similarities and differences are then presented between textbooks of the countries under study. This section also includes an interpretation phase of the possible origins of the types of relationships between man and animal in the textbooks concerned. The results enable one to update the different types of relationships between man and animal found in the science textbooks under scrutiny. Nine types of relationships have been identified. They are: (1) naturalistic; (2) ecologistic; (3) humanistic; (4) moralistic; (5) scientific; (6) aesthetic; (7) utilitarian; (8) dominionistic; and (9) negativistic. The absence of certain categories in some textbooks raises questions on the universality of the values suggested by Kellert's typology (1985). The pre-eminence of the "scientific" category suggests a definite relation with this type of textbook, but also with the general anthropocentric trend generally found in science education. The differences found in

  8. Potential strategies for recovery of lake whitefish and lake herring stocks in eastern Lake Erie

    Science.gov (United States)

    Oldenburg, K.; Stapanian, M.A.; Ryan, P.A.; Holm, E.

    2007-01-01

    Lake Erie sustained large populations of ciscoes (Salmonidae: Coregoninae) 120 years ago. By the end of the 19th century, abundance of lake whitefish (Coregonus clupeaformis) had declined drastically. By 1925, the lake herring (a cisco) population (Coregonus artedii) had collapsed, although a limited lake herring fishery persisted in the eastern basin until the 1950s. In the latter part of the 20th century, the composition of the fish community changed as oligotrophication proceeded. Since 1984, a limited recovery of lake whitefish has occurred, however no recovery was evident for lake herring. Current ecological conditions in Lake Erie probably will not inhibit recovery of the coregonine species. Recovery of walleye (Sander vitreus) and efforts to rehabilitate the native lake trout (Salvelinus namaycush) in Lake Erie will probably assist recovery because these piscivores reduce populations of alewife (Alosa psuedoharengus) and rainbow smelt (Osmerus mordax), which inhibit reproductive success of coregonines. Although there are considerable spawning substrates available to coregonine species in eastern Lake Erie, eggs and fry would probably be displaced by storm surge from most shoals. Site selection for stocking or seeding of eggs should consider the reproductive life cycle of the stocked fish and suitable protection from storm events. Two potential sites in the eastern basin have been identified. Recommended management procedures, including commercial fisheries, are suggested to assist in recovery. Stocking in the eastern basin of Lake Erie is recommended for both species, as conditions are adequate and the native spawning population in the eastern basin is low. For lake herring, consideration should be given to match ecophenotypes as much as possible. Egg seeding is recommended. Egg seeding of lake whitefish should be considered initially, with fingerling or yearling stocking suggested if unsuccessful. Spawning stocks of whitefish in the western basin of Lake

    Full Text Available Union formation and dissolution are among the main determinants explaining variations in fertility. Compared to the rest of Canada, Quebec’s marital histories are more complex and its prevalence of common-law unions much higher. The objective of this article is to examine the role of marital behaviours on fertility by comparing different indicators of fertility and conjugal life that were obtained through microsimulation. Parameters of the microsimulation model were estimated from hazard regressions performed on the marital and fertility histories collected in two retrospective longitudinal surveys: the Canadian General Social Survey (GSS 2001 and 2006. Results show that the more complex marital histories of Quebecers can explain more than one-quarter of their fertility differences with the rest of the country.

  13. Are Quebec’s Future Teachers Ready to Use ICT in Class? The Case of Prospective Teachers in Quebec, Canada

    Full Text Available Are Quebec’s future teachers ready to integrate information and communication technologies (ICT into the scholastic context? To answer this question, a study was conducted with some 2,065 future teachers, 410 associate professors and 90 supervisors of teaching practices from nine French-speaking Quebec universities offering a beginning teacher-training program. The results show that these prospective teachers have access to the equipment needed to become familiar with ICT, and that they use basic technology skills well. Furthermore, the data collected revealed that teachers in training use ICT regularly and reflectively to plan their classes, communicate, search for information, prepare didactic materials, solve problems, or improve themselves professionally. Although the profile shown is promising, the study results also indicate a very low proportion of future teachers who use ICT in the classroom.

    2000-01-01

    This ASTER image was acquired on July 29, 2000 and covers an area of 30 by 57 km in northern Italy. Lake Garda was formed by glaciers during the last Ice Age, and is Italy's largest lake. Lago di Garda lies in the provinces of Verona, Brescia, and Trento, and is 51 kilometers (32 miles) long and from 3 to 18 kilometers (2 to 11 miles) wide. The Sarca is its chief affluent, and the lake is drained southward by the Mincio, which discharges into the Po River. Many villas are situated on its shores. On the peninsula of Sirmione, at the southern end of the lake, are the ruins of a Roman villa and a castle of the Scaligers, an Italian family of the 16th century. The RIGHT image has the land area masked out, and a harsh stretch was applied to the lake values to display variations in sediment load. Also visible are hundreds of boats and their wakes, criss-crossing the lake.The image is centered at 45.6 degrees north latitude, 10.6 degrees east longitude. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface.The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping

  15. Effects of climate on West Nile Virus transmission risk used for public health decision-making in Quebec

    Full Text Available Abstract Background In 2002, major human epidemics of West Nile Virus (WNV were reported in five cities in the North East region of North America. The present analysis examines the climatic conditions that were conducive to the WNV epidemic, in order to provide information to public health managers who eventually must decide on the implementation of a preventive larvicide spraying program in Quebec, Canada. Two sets of variables, the first observed in the summer of 2002 and the second in the preceding winter were analysed to study their potential as explanatory variables for the emergence of the virus at epidemic levels. Results Results show that the climatic conditions observed in the year 2002 have contributed to the emergence of the virus and can be observed once every forty years on average. The analysis has shown that the 2002 events observed in several North East North American cities are characterized by two main variables: the number of degree-days below -5°C in the winter (DD-5 and the number of degree-days greater than 25°C in the summer (DD25. Conclusion In the context of a declining rate of human and aviary infection to WNV, this element contributed to the decision to suspend the use of preventive larvicides in the province of Quebec in 2006 and for the foreseeable future. The second part of this study indicates that it is very important to estimate the risk that extreme values can be observed simultaneously in the summer and in the winter preceding the appearance of the virus. The proposed models provide important information to public health officials, weeks before the appearance of the virus, and can therefore be useful to help prevent human epidemics.

    One hundred ninety-eight groundwater wells were sampled to measure the (222)Rn activity in the region between Montreal and Quebec City, eastern Canada. The aim of this study was to relate the spatial distribution of (222)Rn activity to the geology and the hydrogeology of the study area and to estimate the potential health risks associated with (222)Rn in the most populated area of the Province of Quebec. Most of the groundwater samples show low (222)Rn activities with a median value of 8.6 Bq/L. Ninety percent of samples show (222)Rn activity lower than 100 Bq/L, the exposure limit in groundwater recommended by the World Health Organization. A few higher (222)Rn activities (up to 310 Bq/L) have been measured in wells from the Appalachian Mountains and from the magmatic intrusion of Mont-Saint-Hilaire, known for its high level of indoor radon. The spatial distribution of (222)Rn activity seems to be related mainly to lithology differences between U-richer metasediments of the Appalachian Mountains and magmatic intrusions and the carbonaceous silty shales of the St. Lawrence Platform. Radon is slightly enriched in sodium-chlorine waters that evolved at contact with clay-rich formations. (226)Ra, the parent element of (222)Rn could be easily adsorbed on clays, creating a favorable environment for the production and release of (222)Rn into groundwater. The contribution of groundwater radon to indoor radon or by ingestion is minimal except for specific areas near Mont-Saint-Hilaire or in the Appalachian Mountains where this contribution could reach 45% of the total radioactive annual dose.

  17. The changing epidemiology of meningococcal disease in Quebec, Canada, 1991-2011: potential implications of emergence of new strains.

    Directory of Open Access Journals (Sweden)

    Rodica Gilca

    Full Text Available BACKGROUND: In order to inform meningococcal disease prevention strategies, we analysed the epidemiology of invasive meningococcal disease (IMD in the province of Quebec, Canada, 10 years before and 10 years after the introduction of serogroup C conjugate vaccination. METHODOLOGY: IMD cases reported to the provincial notifiable disease registry in 1991-2011 and isolates submitted for laboratory surveillance in 1997-2011 were analysed. Serogrouping, PCR testing and assignment of isolates to sequence types (ST by using multilocus sequence typing (MLST were performed. RESULTS: Yearly overall IMD incidence rates ranged from 2.2-2.3/100,000 in 1991-1992 to 0.49/100,000 in 1999-2000, increasing to 1.04/100,000 in 2011. Among the 945 IMD cases identified by laboratory surveillance in 1997-2011, 68%, 20%, 8%, and 3% were due to serogroups B, C, Y, and W135, respectively. Serogroup C IMD almost disappeared following the implementation of universal childhood immunization with monovalent C conjugate vaccines in 2002. Serogroup B has been responsible for 88% of all IMD cases and 61% of all IMD deaths over the last 3 years. The number and proportion of ST-269 clonal complex has been steadily increasing among the identified clonal complexes of serogroup B IMD since its first identification in 2003, representing 65% of serogroup B IMD in 2011. This clonal complex was first introduced in adolescent and young adults, then spread to other age groups. CONCLUSION: Important changes in the epidemiology of IMD have been observed in Quebec during the last two decades. Serogroup C has been virtually eliminated. In recent years, most cases have been caused by the serogroup B ST-269 clonal complex. Although overall burden of IMD is low, the use of a vaccine with potential broad-spectrum coverage could further reduce the burden of disease. Acceptability, feasibility and cost-effectiveness studies coupled with ongoing clinical and molecular surveillance are necessary in

    Full Text Available The emergence and spread of carbapenemase-producing Enterobacteriaceae (CPE represent a major public health concern because these bacteria are usually extensively resistant to most antibiotics. In order to evaluate their dissemination in Quebec, a surveillance program was introduced in 2010. We report the molecular and epidemiological profiles of CPE isolates collected. Between August 2010 and December 2012, a total of 742 non-duplicate isolates non-susceptible to carbapenems were analysed. AmpC β-lactamase and metallo-β-lactamase production were detected by Etest and carbapenemase production by the modified Hodge test (MHT. Antibiotic susceptibility profiles were determined using broth microdilution or Etest. Clonality of Klebsiella pneumoniae carbapenemase (KPC strains was analyzed by pulsed-field gel electrophoresis (PFGE. The presence of genes encoding carbapenemases as well as other β-lactamases was detected using PCR. Of the 742 isolates tested, 169 (22.8% were CPE. Of these 169 isolates, 151 (89.3% harboured a blaKPC gene while the remaining isolates carried blaSME (n = 9, blaOXA-48 (n = 5, blaNDM (n = 3, and blaNMC (n = 1 genes. Among the 93 KPC strains presenting with a unique pattern (unique PFGE pattern and/or unique antibiotics susceptibility profile, 99% were resistant to ertapenem, 95% to imipenem, 87% to meropenem, 97% to aztreonam, 31% to colistin and 2% to tigecycline. In 19 patients, 2 to 5 KPC strains from different species or with a different PFGE pattern were isolated. CPE strains were present in the province of Quebec with the majority of strains harbouring KPC. Alternately, SME, OXA-48 and NMC containing strains were rarely found.

    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 coupled atmospheric transport, soil-air, water-air exchange model was developed to investigate the impacts of gamma-hexachlorocyclohexane (gamma-HCH or lindane) usage in the Canadian prairies over the Great Lakes region. The fate of gamma-HCH in air and soil is governed by atmospheric dynamics and physical and chemical processes that are described by the coupled model. These processes include transport and turbulent diffusion in the atmosphere, dry and wet deposition, exchange at the interfacial boundaries of air-water and soil-air, and removal processes from the soil such as diffusion, leaching, and degradation. Numerical experiments were conducted for the period of May 1, 1998-April 30, 1999, starting with application of lindane in the spring. The coupled model was executed with two lindane emission (usage) inventories in the model domain. The first scenario contained all known fresh emission sources in Canada-98% was usage in the prairies; the second excluded emission sources from Ontario and Quebec. The model showed that, in the absence of the reemission from past application of lindane, usage of lindane in Ontario and Quebec has a negligible impact on air concentrations in these regions and that the lindane budget in the Great Lakes ecosystem is mostly attributed to applications of lindane in the canola fields in Canadian prairie provinces. Model-predicted air concentrations and seasonal trends agreed well with measured data over the same time period for several background sites operated under the Integrated Atmospheric Deposition Network. Air temperature was shown to play a key role on surface-air exchange dynamics of gamma-HCH. A future paper will assess loadings to the Great Lakes based on these validated model results.

    2004-07-01

    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

    We simulate the seasonal cycle of the Great Lakes' water temperature and lake ice using an idealized coupled lake-atmosphere-ice model. Under identical seasonally varying boundary conditions, this model exhibits more than one seasonally varying equilibrium solutions, which we associate with distinct regional climate regimes. Colder/warmer regimes are characterized by abundant/scarce amounts of wintertime ice and cooler/warmer summer temperatures, respectively. These regimes are also evident in the observations of the Great Lakes' climate variability over recent few decades, and are found to be most pronounced for Lake Superior, the deepest of the Great Lakes, consistent with model predictions. Multiple climate regimes of the Great Lakes also play a crucial role in the accelerated warming of the lakes relative to the surrounding land regions in response to larger-scale global warming. We discuss the physical origin and characteristics of multiple climate regimes over the lakes, as well as their implications for a longer-term regional climate variability.

    Aquatic ecosystems such as the Great Lakes are known to be contaminated with chemicals that are toxic to fish. However, the role of these contaminants in reproductive failures of fishes, such as lake trout recruitment, has remained controvertible. It was the objective to evaluate dioxin-like embryotoxicity of a complex mixture of chemicals and predict their potential to cause the lack of recruitment in Great Lakes lake trout. Graded doses of a complex environmental extract were injected into eggs of both rainbow trout and lake trout. The extract was obtained from whole adult lake trout collected from Lake Michigan in 1988. The extract was embryotoxic in rainbow trout, with LD50 values for Arlee strain and Erwin strain of 33 eggEQ and 14 eggEQ respectively. The LOAEL for hemorrhaging, yolk-sac edema, and craniofacial deformities in rainbow trout were 2, 2, and 4 eggEQ, respectively. Subsequent injections of the extract into lake trout eggs were likewise embryotoxic, with an LD50 value of 7 eggEQ. The LOAEL values for the extract in lake trout for hemorrhaging, yolk-sac edema, and craniofacial deformities were 0.1, 1, and 2 eggEQ, respectively. The current levels of contaminants in lake trout eggs are above the threshold for hemorrhaging and yolk-sac edema. The results also support the use of an additive model of toxicity to quantify PCDDs, PCDFs, Non-o-PCBs, and Mono-o-PCBs in relation to early life stage mortality in Lake Michigan lake trout.

    The ICDP SCOPSCO project at Lake Ohrid in Macedonia and Albania was one of the most successful lake drilling campaigns worldwide. Drilling took place from April to June 2013 and yielded more than 2000 m of sediments from four different sites in the lake. The maximum penetration was 569 m below lake floor and the overall recovery at all drill sites was > 95 %. Almost two years after the drilling operation, core opening and processing as well as biological and geological analyses are still ongoing. However, most of the cores from the main drill site, the so-called DEEP site in the centre of the lake, are meanwhile opened and reveal a unique record of lake history. The extraordinary quality of seismic, borehole logging and core data allows us to achieve the major goals of the SCOPSCO project. Seismic data, diatoms and coarse-grained sediments in the basal cores indicate that Lake Ohrid had no marine origin, as it was speculated in the past. The data show that Lake Ohrid established in a highly dynamic pull-apart basin with varying fluvial and shallow water conditions. On top of these basal sediments, borehole logging data, XRF scanning data, carbonate, and the amount of organic matter indicate a complete and high resolution succession of glacial / interglacial cycles and interspersed stadials and interstadials. This allows us to determine the establishment of Lake Ohrid by means of chronostratigraphic tuning to about 1.3 to 1.5 Ma ago. Additional, independent age control is given by paleomagnetic data and by numerous tephra layers, which can be correlated with well-dated proximal tephra deposits in Italy. The uppermost 350 m of the sediment record contain more than 30 tephras, which makes the Lake Ohrid record to the rosetta stone of distal Italian tephra deposits in the Balkan region. The unique sediment record of Lake Ohrid is fundamental to obtain crucial information on the overall goal of the SCOPSCO project, i.e. to clarify why Lake Ohrid has one of highest

  3. Feeding competition between larval lake whitefish and lake herring

    Science.gov (United States)

    Savino, Jacqueline F.; Hudson, Patrick L.

    1995-01-01

    The potential for competition for food between larval lake whitefish (Coregonus clupeaformis) and lake herring (C. artedi) 1- to 8-wk of age was explored in a series of 1-h laboratory feeding studies. Feeding started at 2-wk post-hatch. Learning and fish size appear to be more important than prey density at the onset of feeding. Species differed in their feeding behavior and consumption noticeably by 5-wk and substantially by 8-wk. Lake whitefish generally were more aggressive foragers than lake herring, attacking and capturing more prey. At high plankton density at 8-wk, lake herring feeding was depressed in mixed-fish treatments. This difference in competitive food consumption between the two coregonids occurs at a critical life stage, and when combined with other biotic and abiotic factors, may have a significant impact on recruitment.

    2009-01-01

    This paper explores the architecture of the Mount Sinai Sanatorium in Sainte-Agathe-des-Monts (Qc) to disentangle the role of religion in the treatment of tuberculosis. In particular, we analyze the design of Mount Sinai, the jewel in the crown of Jewish philanthropy in Montreal, in relation to that of the nearby Laurentian Sanatorium. While Mount Sinai offered free treatment to the poor in a stunning, Art Deco building of 1930, the Protestant hospital had by then served paying patients for more than two decades in a purposefully home-like, Tudor-revival setting. Using architectural historian Bernard Herman's concept of embedded landscapes, we show how the two hospitals differed in terms of their relationship to site, access, and, most importantly, to city, knowledge, and community. Architects Scopes & Feustmann, who designed the Laurentian hospital, operated an office at Saranac Lake, New York, America's premier destination for consumptives. The qualifications of Mount Sinai architects Spence & Goodman, however, derived from their experience with Jewish institutions in Montreal. Following Herman's approach to architecture through movement and context, how did notions of medical therapy and Judaism intersect in the plans of Mount Sinai?

    An overview is provided of the positive impacts of the James Bay hydroelectric development on the native peoples of the northern Quebec region. The James Bay and Northern Quebec Agreement and its history is first reviewed, then some impacts of the LaGrande Complex development in the James Bay area are described. These include considerable progress in health care and social services, native management of the educational system, protection and encouragement of the traditional local economy, improvement of the local transportation system, increased native economic activity, and population growth. Environmental impacts are being reviewed on an ongoing basis, and environmental mitigation and enhancement programs are being carried out. Some environmental effects of the hydroelectric developments on waterfowl habitats, caribou herds, microclimate, and mercury levels in fish are noted. It is felt that these are minimal, or in the case of mercury levels, that they will diminish and stabilize over the long term. 1 tab.

    The business model and strategic position of Quebec's rural foundries at the beginning of the 20th century is virtually unknown. Inferences have been made based on pictorial and oral data sources. This data reveals that successful rural foundries were, in essence, confined to producing and selling agricultural tools to local farmers on an as-needed basis, because large urban foundries were already mass-producing domestic and industrial objects.

    Unique to the surface of Europa, chaos terrain is diagnostic of the properties and dynamics of its icy shell. While models have suggested that partial melt within a thick shell or melt-through of a thin shell may form chaos, neither model has been able to definitively explain all observations of chaos terrain. However, we present a new model that suggests large melt lenses form within the shell and that water-ice interactions above and within these lenses drive the production of chaos. Our analysis of the geomorphology of Conamara Chaos and Thera Macula, was used to infer and test a four-stage lens-collapse chaos formation model: 1) Thermal plumes of warm, pure ice ascend through the shell melting the impure brittle ice above, producing a lake of briny water and surface down draw due to volume reduction. 2) Surface deflection and driving force from the plume below hydraulically seals the water in place. 3) Extension of the brittle ice lid generates fractures from below, allowing brines to enter and fluidize the ice matrix. 4) As the lens and now brash matrix refreeze, thermal expansion creates domes and raises the chaos feature above the background terrain. This new "lense-collapse" model indicates that chaos features form in the presence of a great deal of liquid water, and that large liquid water bodies exist within 3km of Europa's surface comparable in volume to the North American Great Lakes. The detection of shallow subsurface "lakes" implies that the ice shell is recycling rapidly and that Europa may be currently active. In this presentation, we will explore environments on Europa and their analogs on Earth, from collapsing Antarctic ice shelves to to subglacial volcanos in Iceland. I will present these new analyses, and describe how this new perspective informs the debate about Europa's habitability and future exploration.

  16. Lake-floor sediment texture and composition of a hydrothermally-active, volcanic lake, Lake Rotomahana

    2016-03-01

    Young volcanic lakes undergo a transition from rapid, post-eruptive accumulation of volcaniclastic sediment to slower pelagic settling under stable lake conditions, and may also be influenced by sublacustrine hydrothermal systems. Lake Rotomahana is a young (129 year-old), hydrothermally-active, volcanic lake formed after the 1886 Tarawera eruption, and provides a unique insight into the early evolution of volcanic lake systems. Lake-bottom sediment cores, 20-46 cm in length, were taken along a transect across the lake and characterised with respect to stratigraphy, facies characteristics (i.e., grain size, componentry) and pore water silica concentrations. The sediments generally comprise two widespread facies: (i) a lower facies of light grey to grey, very fine lacustrine silt derived from the unconsolidated pyroclastic deposits that mantled the catchment area immediately after the eruption, which were rapidly reworked and redeposited into the lake basin; and (ii) an upper facies of dark, fine-sandy diatomaceous silt, that settled from the pelagic zone of the physically stable lake. Adjacent to sublacustrine hydrothermal vents, the upper dark facies is absent, and the upper part of the light grey to grey silt is replaced by a third localised facies comprised of hydrothermally altered pale yellow to yellowish brown, laminated silt with surface iron-rich encrustations. Microspheres, which are thought to be composed of amorphous silica, although some may be halloysite, have precipitated from pore water onto sediment grains, and are associated with a decrease in pore water silicon concentration. Lake Rotomahana is an example of a recently-stabilised volcanic lake, with respect to sedimentation, that shows signs of early sediment silicification in the presence of hydrothermal activity.

  17. The 11/25/88, M=6 Saguenay Earthquake near Chicoutimi, Quebec: Evidence for anisotropic wave propagation in northeastern North America

    Science.gov (United States)

    Hough, S. E.; Jacob, K. H.; Friberg, P. A.

    1989-07-01

    On November 25, 1988, a magnitude 6 earthquake occurred in the province of Quebec, Canada. This earthquake triggered nine digital strong motion instruments in New York and Maine at epicentral distances of 200 to 820 km which were installed as part of an effort by the National Center for Earthquake Engineering Research (NCEER) to study ground motions and wave propagation in eastern North America. We calculate Q(f) at discrete frequencies from 0.6 to 26 Hz, assuming that geometrical spreading causes a l/r0.5 decay in spectral amplitudes. Of the nine stations, four are in the Adirondack Mountains in New York and three are in eastern Maine. If we calculate Q(f) for these two clusters of stations separately, we obtain higher values for the Adirondack stations. The Quebec-Adirondack path is along the strike of the predominant structural trends in northeastern North America, in the Grenville Province crust, while the Quebec-Maine path is at high angle to the structural grain and crosses the boundary between the Grenville and the Appalachian provinces. We thus have instrumental data in support of earlier observations based on contours of intensity from historic earthquakes: Seismic wave propagation in northeastern North America is more efficient along the predominantly NE-SW striking geological trends. We address possible biases due to site effects.

    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.

  1. Stereo Pair, with Topographic Height as Color, Manicouagan Crater, Quebec, Canada

    Science.gov (United States)

    2003-01-01

    Manicouagan Crater is one of the world's largest and oldest known impact craters and perhaps the one most readily apparent to astronauts in orbit. The age of the impact is estimated at 214 million years before present. Since then erosion has removed about one kilometer (0.6 miles) of rock from the region and has created a topographic pattern that follows the structural pattern of the crater. A ring depression (prominently seen as green) encloses a central peak. The ring depression now hosts the Manicouagan Reservoir and so appears as a distinct ring lake to astronauts and as a smooth and flat feature in this topographic visualization. A fine pattern of topographic striations trending south-southeast, most prominent within the crater itself, indicates the flow direction of glaciers that covered this area during the last ice age. Three visualization methods were combined to produce this image: shading, color coding, and synthetic stereoscopy. The shade image was derived by computing topographic slope in the north-south direction. Northern slopes appear bright and southern slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow, red, and magenta, to blue at the highest elevations. The stereoscopic effect was then created by generating two differing perspectives, one for each eye. The image can be seen in 3-D by viewing the left image with the right eye and the right image with the left eye (cross-eyed viewing) or by downloading, printing, and splitting the image pair and viewing them with a stereoscope. When stereoscopically merged, the result is a vertically exaggerated view of Earth's surface in its full three dimensions. Total topographic relief from the ring lake level to the central crater peak is about 600 meters (2000 feet). Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on February 11, 2000. The

    For the last couple of decades, the Great Lakes have undergone rapid surface warming. In particular, the magnitude of the summer surface-warming trends of the Great Lakes have been much greater than those of surrounding land (Austin and Colman, 2007). Among the Great Lakes, the deepest Lake Superior exhibited the strongest warming trend in its annual, as well as summer surface water temperature. We find that many aspects of this behavior can be explained in terms of the tendency of deep lakes to exhibit multiple regimes characterized, under the same seasonally varying forcing, by the warmer and colder seasonal cycles exhibiting different amounts of wintertime lake-ice cover and corresponding changes in the summertime lake-surface temperatures. In this thesis, we address the problem of the Great Lakes' warming using one-dimensional lake modeling to interpret diverse observations of the recent lake behavior.

    Full Text Available Salinity surveys in 1997 revealed that in the dry season salinity in Thale Sap Songkhla, Thale Sap and Thale Luang reached the maximum values of 30, 11 and 5 ppt, respectively. Among the complex system of the lake, Khlong Pak Ro showed a complicate seawater transport with a maximal salinity of 20 ppt. Incomplete mixing with a stratification at a depth of 2-3 m occured. The difference in salinity between the surface and the bottom was about 3 ppt. A vertically-averaged salt transport model was employed to simulate the salinity intrusion in the lake. The results showed quite good agreement with the observation. The model depicted a sharp drop of the water level at the entrance from the Gulf into the lake. The tidal energy then spread widely in Thale Sap Songkhla and continuously decreased to Thale Luang. The predicted salinity indicated that salt transport in the lake is governed by tide and water losses from the lake. Tidal movement generated a quasi-steady state of salinity in three months. The water losses for two months caused the salinity to rise 5.8 ppt/1 mm/day loss (~13 m3/sat Pak Ro. With a loss of 2.3 mm/day (~28 m3/s, the whole lake became brackish in three months. The salt entered the lake mainly through Khlong Luang, and only for 13 percent through Ao Thong Ben.

    A comprehensive rehabilitation plan was developed and implemented to shift Delavan Lake, Wisconsin, from a hypereutrophic to a mesotrophic condition. The plan was threefold: (1) reduce external phosphorus (P) loading by applying Best Management Practices in the watershed, enhance an existing wetland, and short-circuit the inflows through the lake, (2) reduce internal P loading by treating the sediments with alum and removing carp, and (3) rehabilitate the fishery by removing carp and bigmouth buffalo and adding piscivores (biomanipulation). The first and second parts of the plan met with only limited success. With only minor reductions in internal and external P loading, P concentrations in the lake returned to near pre-treatment concentrations. The intensive biomanipulation and resulting trophic cascade (increased piscivores, decreased planktivores, increased large zooplankton populations, and reduced phytoplankton populations) eliminated most of the original problems in the lake (blue-green algal blooms and limited water clarity). However, now there is extensive macrophyte growth and abundant filamentous algae. Without significantly reducing the sources of the problems (high P loading) in Delavan Lake, the increased water clarity may not last. With an improved understanding of the individual components of this rehabilitation program, better future management plans can be developed for Delavan Lake and other lakes and reservoirs with similar eutrophication problems.

  15. Recent dynamics of thermokarst ponds in discontinuous permafrost: a paleolimnological study from subarctic Quebec, Canada

    Accelerated thawing and erosion of permafrost is leading to the release of organic carbon through greenhouse gas emissions, especially in thermokarst (thaw) ponds and lakes. These aquatic ecosystems are widespread throughout arctic and subarctic regions; however their natural variability and temporal evolution recorded in the bottom sediments are poorly understood. Here we present a multi-proxy study conducted in a subarctic site with many thermokarst ponds near Kuujjuarapik-Whapmagoostui, on the eastern shore of Hudson Bay, at the southern edge of the discontinuous and scattered permafrost zone. Sedimentological, geochemical and biological (diatoms) analyses have been performed on short sediment cores (10-20 cm) retrieved from limnologically contrasted ponds. Long-term (14C) and short-term (210Pb, 137Cs) chronologies were also established. Analyses revealed two distinct sedimentary facies, from bottom to top: 1) massive marine silts and clays deposited during postglacial Tyrrell Sea transgression (ca. 8000 to 6000 cal yr BP), subsequently emerged by glacio-isostatic rebound and more recently (ca. 1500 to 400 cal yr BP) affected by permafrost inception and growth; 2) laminated organic-rich lacustrine muds deposited since permafrost thawing and subsidence, i.e. since thermokarst pond inception (the last centuries). Almost absent from the bottom sediments (lower facies), benthic and planktonic diatoms appeared highly abundant in surface lacustrine sediments (upper facies) and reflected past changes in bottom water properties (e.g., pH, dissolved organic carbon, water color). Despite displaying strikingly different water colors, the study ponds showed similar long-term developmental patterns regarding their biogeochemical properties (as recorded in the sediments), such as: decreasing mineral grain size (from silts to clays); decreasing major chemical element concentrations; increasing organic matter content and decreasing pH (establishment of peatland vegetation

    Even though health inequalities are conditioned by many aspects of the environment, much of the existing research focuses on the social environment. This emphasis has the effect to neglect other environmental aspects such as its physical dimension. The physical environment, which is linked to housing conditions, may contribute to the uneven distribution of health. In this study, we examined 19 housing-related issues among a representative sample of 2,000 adults residing in a Quebec (Canada) health region characterized by a mix of rural, semi-rural, and urban areas. The distribution of these issues was examined according to socioeconomic and geographic indicators of social position. Summary measures of inequalities were assessed. Our results showed that the prevalence of nearly all housing-related issues was higher among low-income households compared to more affluent ones. Highly educated individuals showed better housing conditions, whereas different issues tended to cluster in deprived or densely populated areas. To conclude, we observed steep gradients between social class and poor housing conditions. This may explain a substantial part of health inequality on the regional scale. The surveillance of housing-related issues is therefore essential to properly inform and mobilize local stakeholders and to develop interventions that target vulnerable groups on this level.

    Objectives. We examined associations between residential exposure to BIXI (BIcycle-taXI)—a public bicycle share program implemented in Montreal, Quebec, in 2009, which increases accessibility to cycling by making available 5050 bicycles at 405 bicycle docking stations—and likelihood of cycling (BIXI and non-BIXI) in Montreal over the first 2 years of implementation. Methods. Three population-based samples of adults participated in telephone surveys. Data collection occurred at the launch of the program (spring 2009), and at the end of the first (fall 2009) and second (fall 2010) seasons of implementation. Difference in differences models assessed whether greater cycling was observed for those exposed to BIXI compared with those not exposed at each time point. Results. We observed a greater likelihood of cycling for those exposed to the public bicycle share program after the second season of implementation (odds ratio = 2.86; 95% confidence interval = 1.85, 4.42) after we controlled for weather, built environment, and individual variables. Conclusions. The implementation of a public bicycle share program can lead to greater likelihood of cycling among persons living in areas where bicycles are made available. PMID:23327280

  18. Initial mandate concerning the problem of fluctuating gasoline prices and their effect on the Quebec economy : Final report

    International Nuclear Information System (INIS)

    Over a three-year period covering May 1998 to May 2001, the average price of gasoline in Quebec slowly increased from 57.1 cent per litre to 82.6 cent per litre. This 45 per cent increase in the price of gasoline worried consumers and had an effect on commercial and industrial operations throughout the province. This situation prompted the Commission de l'economie et du travail (Commission on Labour and the Economy) to initiate a mandate to examine the problem. In October 2001, experts representing energy and taxation sectors were consulted and presentations made by 17 people and organizations. The Ministre des Ressources Naturelles (Minister of Natural Resources) and the President de la Regie de l'Energie were heard in a public consultation forum. In the first part of the document, the authors explained the mechanism by which the price of gasoline and its various components are determined, identified the elements responsible for the increases in prices, and compare the prices in the different parts of the province. In part two, the responsibilities and powers of the Ministry of Natural Resources and the Regie de l'Energie with regard to petroleum products were examined. Part three described the opinions expressed and proposed recommendations obtained during the public consultation process and they were grouped under four headings: taxation, competition, consumer information, and energy savings. The final part of the document presented the recommendations of the Commission on Labour and the Economy. 15 refs., 5 tabs

  19. Hydro-Quebec and geomagnetic storms: measurement techniques, effects on transmission network and preventive actions since 1989.

    Science.gov (United States)

    Beland, J.

    In March 1989 the province of Quebec in Canada suffered an almost complete blackout during a severe geomagnetic storm. Millions of Hydro-Québec's customers have been left without electricity for several hours. Fifteen years later, many changes have been implemented to avoid the repetition of such an event. Among them, we now have two measurement systems (one primary and one backup) monitoring ground induced current (GIC) effects on the grid in real time. Those systems are described and examples of data acquired during major storms (as in late October 2003) are given. To be informed in advance of a probable GIC occurrence, HQ now relies on a specialized organization providing geomagnetic activity alert and forecast. Following an alert or the detection of GIC effects on the network exceeding a minimal threshold, special operation rules become in effect with the objective of ensuring maximum stability and safety margin. Another major improvement is the introduction of series capacitors on several 735 kV lines, which increases network stability and also block GIC circulation. In conclusion, HQ now believes that its network can survive to any realistic geomagnetic storm.

  20. Bringing home methylmercury: The construction of an authoritative object of knowledge for a Cree community in northern Quebec

    International Nuclear Information System (INIS)

    Aspects of the construction of methylmercury as an authoritative object of knowledge is examined for the case of Chisasibi, a Cree community on the James Bay coast in northern Quebec. The community is located near large hydroelectric projects, and an extensive institutional apparatus has been established in the Chisasibi area to provide research and education about the resulting contamination of water and fish by methylmercury released by flooding of lands by hydro reservoirs. The historical development of the Cree community is reviewed and the evolution of a particular set of spheres of exchange which mediate economic relations in the region is described. Such relations occur between the Cree communities, the federal and provincial governments, and state and corporate structures tied to the state. Knowledge claims about mercury can be seen as situated among claims of injury in a moral economy which is based on conflict over the James Bay hydroelectric project. The politicization and subsequent medicalization of these knowledge claims are described. Finally, the emergence of particular concepts of normality, risk, and risk group are traced in medical and technocratic discourses about the effects of methylmercury on Canadian aboriginal populations. 122 refs., 2 figs., 3 tabs

  1. Remote sensing of spruce budworm defoliation using EO-1 Hyperion hyperspectral data: an example in Quebec, Canada

    Huang, Z.; Zhang, Y.

    2016-04-01

    Each year, the spruce budworm (SBW) causes severe, widespread damage to spruces and fir in east coast Canada. Early estimation of the defoliation can provide crucial support to mitigate the socio-economic impact on vulnerable forests. Remote sensing techniques are suitable to investigate the affected regions that usually consist of large and inaccessible forestry areas. Using satellite images, surface reflectance values at two or more wavelengths are combined to generate vegetation indices (VIs), revealing a relative abundance of features of interest. Forest health analysis based on VIs is considered as one of the primary information sources for monitoring vegetation conditions. Especially the spectral resolution of Hyperion hyperspectral satellite imagery used in this study allows for a detailed examination of the red to near-infrared portion of the spectrum to identify areas of stressed vegetation. Several narrow-band vegetation indices are used to indicate the overall amount and quality of photosynthetic material and moisture content in vegetation. By integrating the information from VIs that focus on different aspects of overall health and vigour in forested areas, the study aims at detecting defoliated condition in a forested region in the Province of Quebec, Canada. In June and August of 2014 two Hyperion images were acquired by NASA's EO-1 satellite for this study. Changes in vegetation health and vigour are observed and quantitatively compared using the multi-temporal remote sensing images. The experimental results suggest that the VI- based forest health analysis is effective in estimating SBW defoliation in the study area.

  2. Estimating the mercury exposure dose in a population of migratory bird hunters in the St. Lawrence River region, Quebec, Canada

    International Nuclear Information System (INIS)

    St. Lawrence River hunters (Quebec, Canada) are exposed to the pollutants, especially mercury, that contaminate birds and fish. However, the health risks of this have remained unclear because of a lack of information about the hunters' duck, geese, and sportfish consumption habits. A nutritional survey was set up to characterize waterfowl and sportfish consumption in St. Lawrence River duck hunters and to estimate their daily exposure to mercury. During the winter of 2000, 512 hunters selected from the Canadian Wildlife Service database completed a self-administered questionnaire. Daily exposure to contaminants was measured using data from the Canadian Wildlife Service (waterfowl) and available data on St. Lawrence River sportfish. The annual average consumption was 7.5 meals of ducks and geese and 8.7 meals of sportfish. The daily exposure to mercury related to waterfowl consumption was below the Canadian tolerable daily intake (TDI) of 0.47 μg/kg body wt/day for all participants. The daily mercury intake associated with fish consumption was greater than the TDI in 2 duck hunters. The daily exposure to mercury was higher than the TDI in 4 participants when both waterfowl and fish consumption were combined. Our results suggest that fish consumption (especially freshwater fish) represents the main source of exposure to pollutants in duck hunters

    Waste-to-energy provides a solution to two problems: waste management and energy generation. An integrated anaerobic waste valorization process is an interesting option, but because of investments cost and low energy value in the province of Quebec, it is hard for a municipality to commit to that solution. This paper investigated the economic possibilities to manage organic material, organic fraction of municipal solid waste, and municipal wastewater sludge by anaerobic digestion for a 150,000 inhabitant municipality, with consideration to energy generation and greenhouse gas emission reduction. Using the biogas to co-generation solution brings a payback time on investment (PBT) of 3.7 years with electricity price at 0.10 $Cdn/kW h. The addition of manure from surrounding farms increases the biogas production by 37%, but increases the PBT to 6.8 years unless the leftover digestate can be used for agronomic valorization; then it becomes economically advantageous. The natural gas purchasing cost is too low to promote the enrichment of biogas into renewable natural gas. However, this scenario has the lowest energetic payback time (3.3 years) and reduces the most greenhouse gas emissions (4261 tCO{sub 2}eq/a). (author)

    2009-03-01

    Full Text Available Dendrochronology, the scientific dating method based on the analysis of tree-ring growth patterns, has been frequently applied in climatology. The basic premise of dendroclimatology is that tree rings can be viewed as climate proxies, i.e. rings are assumed to contain some hidden information about past climate. From a statistical perspective, this extraction problem can be understood as the search of a hidden variable which represents the common signal within a collection of tree-ring width series. Classical average-based techniques used in dendrochronology have been, with different degrees of success (depending on tree species, regional factors and statistical methods, applied to estimate the mean behavior of this latent variable. Still, a precise quantification of uncertainties associated to the hidden variable distribution is difficult to assess. To model the error propagation throughout the extraction procedure, we propose and study a Bayesian hierarchical model that focuses on extracting an inter-annual high frequency signal. Our method is applied to black spruce (Picea mariana tree-rings recorded in northern Quebec and compared to a classical average-based techniques used by dendrochronologists.

    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. PMID:27381875

    The objective of this paper is to determine the likelihood of an algae bloom in a particular lake located in upstate New York. The growth of algae in this lake is caused by a high concentration of phosphorous that diffuses to the surface of the lake. Our calculations, based on Fick's Law, are used to create a mathematical model of the driving force of diffusion for phosphorous. Empirical observations are also used to predict whether the concentration of phosphorous will diffuse to the surface...

    Hansen, Michael J.; Taylor, William W.; Ferreri, C. Paola

    1999-01-01

    The lake trout (Salvelinus namaycush) was important to the human settlement of each of the Great Lakes, and underwent catastrophic collapses in each lake in the nineteenth and twentieth centuries. The timing of lake trout stock collapses were different in each lake, as were the causes of the collapses, and have been the subject of much scientific inquiry and debate. The purpose of this chapter is to summarize and review pertinent information relating historical changes in Great Lakes lake trout stocks, binational efforts to restore those stocks, and progress toward stock restoration. This presentation attempts to generalize patterns across the Great Lakes, rather than to focus within each lake. Lake specific analyses have been used to understand lake specific causes and effects, but there is continuing debate about some of these causes and effects. A basinwide review may suggest mechanisms for observed changes that are not evident by lake specific analysis.

  17. Morphological variation of siscowet lake trout in Lake Superior

    Science.gov (United States)

    Bronte, C.R.; Moore, S.A.

    2007-01-01

    Historically, Lake Superior has contained many morphologically distinct forms of the lake trout Salvelinus namaycush that have occupied specific depths and locations and spawned at specific times of the year. Today, as was probably the case historically, the siscowet morphotype is the most abundant. Recent interest in harvesting siscowets to extract oil containing omega-3 fatty acids will require additional knowledge of the biology and stock structure of these lightly exploited populations. The objective of this study was to determine whether shape differences exist among siscowet populations across Lake Superior and whether these shape differences can be used to infer stock structure. Morphometric analysis (truss protocol) was used to differentiate among siscowets sampled from 23 locations in Lake Superior. We analyzed 31 distance measurements among 14 anatomical landmarks taken from digital images of fish recorded in the field. Cluster analysis of size-corrected data separated fish into three geographic groups: The Isle Royale, eastern (Michigan), and western regions (Michigan). Finer scales of stock structure were also suggested. Discriminant function analysis demonstrated that head measurements contributed to most of the observed variation. Cross-validation classification rates indicated that 67–71% of individual fish were correctly classified to their region of capture. This is the first study to present shape differences associated with location within a lake trout morphotype in Lake Superior.

    2003-01-01

    A 9.25-m-long sediment core from Bosten Lake, Xinjiang, provides detailed information about changes in the water budget and biological acticity over the last 8400 calendar years. The chronology is constructed from six AMS radiocarbon dates on the terrestrial plant remains. Based on analyses of TOC, CO3, detrital compounds and biogenic SiO2, lake level fluctuations and periods of remarkably-negative water budget appeared at 8.4-8.2 cal ka, 7.38-7.25 cal ka, 5.7-5.5 cal ka, 3.7-3.4 cal ka and 3.3-2.9 cal ka, respectively. As they are in-phase with low lake levels at Sumxi Co and Bangong Co in western Tibet Plateau and with paleolakes in Inner Mongolia, a climate-induced change to somewhat drier andwarmer conditions is inferred. A further drop in lake level after 1320 AD of about 200 yr duration may be attributed to a negative water balance prior to the main phase of the Little Ice Age. Deep and stable lake phases of 1500 yr and 1800yr duration at 7.2-5.7 cal ka and 5.5-3.7 cal ka coincide with maximum moisture during the Holocene Megathermal in China. The long term trend towards ariditysince about 4.3 cal ka can clearly be recognised. The reduced water budget of Bosten Lake from 640-1200 AD may be attributed to local effects.

  19. Isotope investigation of Lake Malawi

    International Nuclear Information System (INIS)

    A vertical tritium and stable isotope profile shows that in the meromictic Lake Malawi water mixes slowly but at a significantly higher rate than in Lake Tanganyika, which has similar morphological characteristics. The tritium balance indicates that half or more of the tritium stored in the lake derives from molecular exchange with the atmospheric moisture. The tritium profile enables the vertical mixing rate in the lake to be computed. For this, a three-box model is used corresponding to epilimnion, metalimnion and hypolimnion. The computation indicates that on the average about 25% of the water is exchanged every year between the epilimnion and the metalimnion and about 20% between the metalimnion and the hypolimnion.

    Soda lakes represent unique permanently haloalkaline system. Despite the harsh conditions, they are inhabited by abundant, mostly prokaryotic, microbial communities. This review summarizes results of studies of main functional groups of the soda lake prokaryotes responsible for carbon, nitrogen and sulfur cycling, including oxygenic and anoxygenic phototrophs, aerobic chemolithotrophs, fermenting and respiring anaerobes. The main conclusion from this work is that the soda lakes are very different from other high-salt systems in respect to microbial richness and activity. The reason for this difference is determined by the major physico-chemical features of two dominant salts - NaCl in neutral saline systems and sodium carbonates in soda lakes, that are influencing the amount of energy required for osmotic adaptation.

    Star patterns, reminiscent of a wide range of diffusively controlled growth forms from snowflakes to Saffman-Taylor fingers, are ubiquitous features of ice covered lakes. Despite the commonality and beauty of these ``lake stars'' the underlying physical processes that produce them have not been explained in a coherent theoretical framework. Here we describe a simple mathematical model that captures the principal features of lake-star formation; radial fingers of (relatively warm) water-rich regions grow from a central source and evolve through a competition between thermal and porous media flow effects in a saturated snow layer covering the lake. The number of star arms emerges from a stability analysis of this competition and the qualitative features of this meter-scale natural phenomena are captured in laboratory experiments.

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...

    It is now fairly well accepted that amphibole asbestos is more harmful upon inhalation than chrysotile, especially for the etiology of mesothelioma. Epidemiological evidence has shown a higher incidence of mesothelioma cases in amphibole asbestos mining districts (e.g., South Africa) as compared to chrysotile mining districts (e.g., southeastern Quebec). However, there have been some reported cases of mesothelioma from the southeastern Quebec region, and most health researchers attribute these to amphibole asbestos occurring at low-levels in some of the ores. The central portion of the district located in or near the town of Thetford Mines appears to have higher concentrations of amphiboles, and mesothelioma cases, while the mines near the edge of the district, for instance the Jeffrey mine located in the town of Asbestos southwest of Thetford Mines, have lower amphibole contents and in turn fewer cases of mesothelioma. Locally, the geology of these chrysotile-bearing ultramafic rocks contains granitic intrusions which provide the needed silica to form amphiboles. These intrusions do not appear to have occurred in the northeastern portion of the district. The medical literature almost always refers to amphiboles in these deposits as tremolites. To further test the hypothesis that the more distant mines farther from the silica-rich intrusions have lower amphibole contents, we collected a suite of samples from the former chrysotile mine operated by Carey Canadian Mines located approximately 20 miles northeast of Thetford Mines. A total of ten samples, six of which were ore samples, two in-place rock samples, and two tailings samples, were first analyzed by routine PLM (polarized light microscopy) dispersion staining and powder X-ray diffraction (XRD) methods. One sample was found to contain trace amounts of an amphibole. Quantitative XRD methods were developed and showed this one sample contained between 500 to 1,000 ppm amphibole; the detection limit of this new XRD

    Full Text Available Fertilizer recommendations for cranberry crops are guided by plant and soil tests. However, critical tissue concentration ranges used for diagnostic purposes are inherently biased by nutrient interactions and physiological age. Compositional data analysis using isometric log ratios (ilr of nutrients as well as time detrending can avoid numerical biases. The objective was to derive unbiased nutrient signature standards for cranberry in Quebec and compare those standards to literature data. Field trials were conducted during 3 consecutive years with varying P treatments at six commercial sites in Quebec. Leaf tissues were analyzed for N, P, K, Ca, Mg, B, Cu, Zn, Mn and Fe. The analytical results were transformed into ilr nutrient balances of parts and groups of parts. High-yield reference ilr values were computed for cranberry yielding greater than 35 Mg ha-1. Many cranberry fields appeared to be over-supplied with K and either under-supplied with Mn or over-supplied with Fe as shown by their imbalanced [K | Ca, Mg] and [Mn | Fe] ratios. Nutrient concentration ranges from Maine and Wisconsin, USA, were combined into ilr values to generate ranges of balances. It was found that these nutrient ranges were much too broad for application in Quebec or outside the Quebec ranges for the [Ca | Mg] and the [Mn | Fe] balances, that were lower compared to those of high yielding cranberry crops in Quebec.As recommendações de fertilizantes da cultura atoca são determinadas a partir de análises de planta e solo.

Lake Dian is in the natural succession process and has entered a period of aging and eutrofication. The lake is shallow lake, and therefore the lake water self-purification ability is weaker and weaker. The major rivers into Lake DIan run through some urban areas, villages, farms, industrial areas; therefore a large number of hazardous substances and nutrients are carried from t...

    In the project described remote sensing was used to check the quality of lake waters. The lakes of three Landsat scenes were mapped with the Bendix MDAS multispectral analysis system. From the MDAS color coded maps, the lake with the worst algae problem was easily located. The lake was closely checked, and the presence of 100 cows in the springs which fed the lake could be identified as the pollution source. The laboratory and field work involved in the lake classification project is described.

    The Mont Ham Massif (part of the Thetford Mines ophiolite, south Quebec) represents a magmatic sequence made up of tholeiitic and boninitic derived products. A geochemical study confirms the multicomponent mixing models that have been classically advanced for the source of boninites, with slab-derived components added to the main refractory harzburgitic peridotite. An isochron diagram of the boninitic rocks is interpreted as a mixing trend between two components: (i) a light rare earth element (LREE) enriched component (A), interpreted as slab-derived fluid-melts equilibrated with sedimentary materials ({epsilon}{sub Nd} = -3, {sup 147}Sm/{sup 144}Nd = 0.140), and (ii) a LREE-depleted component (B) (0.21 < {sup 147}Sm/{sup 144}Nd < 0.23), interpreted as slab-derived fluid-melt equilibrated with recycled Iapetus oceanic crust and equated to the Nd-isotope characteristics of the lapetus mantle ({epsilon}{sub Nd} = 9). A multicomponent source is also necessary to explain the Nd-isotope and trace element composition of the tholeiites, which are explained by the melting of a more fertile, Iherzolitic mantle and (or) mid-ocean ridge basalt source (component C), characterized by a large-ion lithophile element depicted pattern and an lapetus mantle Nd isotopic composition ({epsilon}{sub Nd} = 9), mixed in adequate proportions with the two previously infered slab-derived components (A and B). The genesis of the boninites of Mont Ham is not significantly different from those of boninites located in the Pacific. An intraoceanic subduction zone appears to be an appropriate geodynamic environment for the Mont Ham ophiolitic sequence. (author)

  20. Actinorhizal Alder Phytostabilization Alters Microbial Community Dynamics in Gold Mine Waste Rock from Northern Quebec: A Greenhouse Study.

    Katrina L Callender

    Full Text Available Phytotechnologies are rapidly replacing conventional ex-situ remediation techniques as they have the added benefit of restoring aesthetic value, important in the reclamation of mine sites. Alders are pioneer species that can tolerate and proliferate in nutrient-poor, contaminated environments, largely due to symbiotic root associations with the N2-fixing bacteria, Frankia and ectomycorrhizal (ECM fungi. In this study, we investigated the growth of two Frankia-inoculated (actinorhizal alder species, A. crispa and A. glutinosa, in gold mine waste rock from northern Quebec. Alder species had similar survival rates and positively impacted soil quality and physico-chemical properties in similar ways, restoring soil pH to neutrality and reducing extractable metals up to two-fold, while not hyperaccumulating them into above-ground plant biomass. A. glutinosa outperformed A. crispa in terms of growth, as estimated by the seedling volume index (SVI, and root length. Pyrosequencing of the bacterial 16S rRNA gene for bacteria and the ribosomal internal transcribed spacer (ITS region for fungi provided a comprehensive, direct characterization of microbial communities in gold mine waste rock and fine tailings. Plant- and treatment-specific shifts in soil microbial community compositions were observed in planted mine residues. Shannon diversity and the abundance of microbes involved in key ecosystem processes such as contaminant degradation (Sphingomonas, Sphingobium and Pseudomonas, metal sequestration (Brevundimonas and Caulobacter and N2-fixation (Azotobacter, Mesorhizobium, Rhizobium and Pseudomonas increased over time, i.e., as plants established in mine waste rock. Acetate mineralization and most probable number (MPN assays showed that revegetation positively stimulated both bulk and rhizosphere communities, increasing microbial density (biomass increase of 2 orders of magnitude and mineralization (five-fold.
