  1. Euoplocephalus tutus and the diversity of ankylosaurid dinosaurs in the Late Cretaceous of Alberta, Canada, and Montana, USA.

    Directory of Open Access Journals (Sweden)

    Victoria M Arbour

    Full Text Available Few ankylosaurs are known from more than a single specimen, but the ankylosaurid Euoplocephalus tutus (from the Late Cretaceous of Alberta, Canada and Montana, USA is represented by dozens of skulls and partial skeletons, and is therefore an important taxon for understanding intraspecific variation in ankylosaurs. Euoplocephalus is unusual compared to other dinosaurs from the Late Cretaceous of Alberta because it is recognized from the Dinosaur Park, Horseshoe Canyon, and Two Medicine formations. A comprehensive review of material attributed to Euoplocephalus finds support for the resurrection of its purported synonyms Anodontosaurus lambei and Scolosaurus cutleri, and the previously resurrected Dyoplosaurus acutosquameus. Anodontosaurus is found primarily in the Horseshoe Canyon Formation of Alberta and is characterized by ornamentation posterior to the orbits and on the first cervical half ring, and wide, triangular knob osteoderms. Euoplocephalus is primarily found in Megaherbivore Assemblage Zone 1 in the Dinosaur Park Formation of Alberta and is characterized by the absence of ornamentation posterior to the orbits and on the first cervical half ring, and keeled medial osteoderms on the first cervical half ring. Scolosaurus is found primarily in the Two Medicine Formation of Montana (although the holotype is from Dinosaur Provincial Park, and is characterized by long, back-swept squamosal horns, ornamentation posterior to the orbit, and low medial osteoderms on the first cervical half ring; Oohkotokia horneri is morphologically indistinguishable from Scolosaurus cutleri. Dyoplosaurus was previously differentiated from Euoplocephalus sensu lato by the morphology of the pelvis and pes, and these features also differentiate Dyoplosaurus from Anodontosaurus and Scolosaurus; a narrow tail club knob is probably also characteristic for Dyoplosaurus.

  2. By ship, by barge, by truck : massive Kearl modules to take a new route from South Korea to Alberta via Idaho and Montana highways

    Jaremko, D.

    2010-03-15

    Idaho and Montana highways will be used to transport massive oil sands modules for Imperial Oil's Kearl oilsands project. A test module will pass through the states in mid 2010. The local highway patrol will be contracted as an escort in order to reduce the risk of incidents with local drivers. The modules will be shipped from South Korea to Portland and then transported by barge to Lewiston, Idaho. The modules will then be loaded onto trucks and transported along the highway. It will take approximately 10 days to move the modules to the Kearl site near Fort McMurray, Alberta. The loads are so large that they will not fit through rail tunnels or highway overpasses. Imperial Oil will be required to bury some overhead power transmission lines and build approximately 100 pullouts along the route. Traffic signal arms will also be modified to swing out of the way as the loads are passing through. Construction of the Kearl site will be completed by 2012. 2 figs.

  4. Wind integration in Alberta

    International Nuclear Information System (INIS)

    Frost, W.

    2007-01-01

    This presentation described the role of the Alberta Electric System Operator (AESO) for Alberta's interconnected electric system with particular reference to wind integration in Alberta. The challenges of wind integration were discussed along with the requirements for implementing the market and operational framework. The AESO is an independent system operator that directs the reliable operation of Alberta's power grid; develops and operates Alberta's real-time wholesale energy market to promote open competition; plans and develops the province's transmission system to ensure reliability; and provides transmission system access for both generation and load customers. Alberta has over 280 power generating station, with a total generating capacity of 11,742 MW, of which 443 is wind generated. Since 2004, the AESO has been working with industry on wind integration issues, such as operating limits, need for mitigation measures and market rules. In April 2006, the AESO implemented a temporary 900 MW reliability threshold to ensure reliability. In 2006, a Wind Forecasting Working Group was created in collaboration with industry and the Canadian Wind Energy Association in an effort to integrate as much wind as is feasible without compromising the system reliability or the competitive operation of the market. The challenges facing wind integration include reliability issues; predictability of wind power; the need for dispatchable generation; transmission upgrades; and, defining a market and operational framework for the large wind potential in Alberta. It was noted that 1400 MW of installed wind energy capacity can be accommodated in Alberta with approved transmission upgrades. figs

  6. Congestion management in Alberta

    International Nuclear Information System (INIS)

    Way, R.

    2002-01-01

    The challenges facing Alberta regarding electricity market design and congestion management were described. The electricity market in the province consists of a central power pool, an open access transmission network, and a single pool price, unlike many other jurisdictions in North America which have adopted a location margin price (LMP) design with significant price differences between various locations within the power network. Alberta's transmission network is regulated and provides carrier functions. Power moves freely throughout Alberta's power pool network with no congestion, therefore the common pool price signals market participants throughout the entire network with no segregation into zones. Alberta is currently at a cross road in choosing between a single pool price model or a nodal price model. In the first instance, the province would have to strengthen the transmission network to maintain the market at a reasonable size. The alternative would permit Alberta to use market-based techniques to deal with the evolution of many smaller markets in the province, but these would be very small by North American standards and their ability to compete would be questionable

  7. Transmission issues in Alberta

    International Nuclear Information System (INIS)

    Levson, D.

    2002-01-01

    This paper outlined the major issues and concerns facing users of the transmission system in Alberta. They include congestion management issues that make investors uncertain about power generation. It is necessary to know the difference between which transmission price signals will be faced by low cost cogeneration at Fort McMurray and Cold Lake coal-fired generation near Edmonton compared to combined cycle gas generation near Calgary. Import and export policy tariffs are another concern. Most new generation opportunities in Alberta require access to export markets, but transmission facilities for export need policy support and appropriate tariffs. It was noted that the past actions of Alberta's Transmission Administrator and balancing pool may be distorting market signals for ancillary service markets, and that loss studies and calculations need upgrading

  8. Reforming Long-Term Care Funding in Alberta.

    Crump, R Trafford; Repin, Nadya; Sutherland, Jason M

    2015-01-01

    Like many provinces across Canada, Alberta is facing growing demand for long-term care. Issues with the mixed funding model used to pay long-term care providers had Alberta Health Services concerned that it was not efficiently meeting the demand for long-term care. Consequently, in 2010, Alberta Health Services introduced the patient/care-based funding (PCBF) model. PCBF is similar to activity-based funding in that it directly ties the complexity and care needs of long-term care residents to the payment received by long-term care providers. This review describes PCBF and discusses some of its strengths and weaknesses. In doing so, this review is intended to inform other provinces faced with similar long-term care challenges and contemplating their own funding reforms.

  9. Southern Alberta system reinforcement

    Energy Technology Data Exchange (ETDEWEB)

    Rehman, A. [Alberta Electric System Operator, Calgary, AB (Canada)

    2008-07-01

    System planning for the Alberta Electric System Operator's (AESO) southern system was discussed in view of the growing interest in developing wind energy resources in the province. While Alberta currently has a total of 11,500 MW of installed wind power, southern Alberta has a very small capability for interconnecting additional wind resources. There are 3 main agencies involved in system planning for the southern region: (1) the Alberta Utilities Commission (AUC), (2) the AESO, and (3) the transmission facility owners. Transmission needs are studied by the AESO, who then applies to the AUC for approval. Transmission facility owners also apply to the AUC for approval to construct facilities. The AESO's roles are to operate the wholesale electricity market; plan the transmission system; arrange access for loads and generation; and oversee transmission system operation. The AESO is an independent agency with a public interest mandate. The AESO's queue management process has been designed to facilitate non-discriminatory system access. Development options currently being considered by the AESO include a 240 kV AC transmission line; a 500 kV AC transmission line; a 765 kV AC transmission line; a high voltage direct current (HVDC) system; and a voltage source converter (VSC) HVDC system. Radial and looped configurations are also being considered. The AESO is currently conducting a participant involvement program that involves open houses with the Canadian Wind Energy Association (CanWEA) and other provincial stakeholders. tabs., figs.

  10. Power deregulation in Alberta

    International Nuclear Information System (INIS)

    MacMurchy, N.E.

    1999-01-01

    The impacts of deregulation of the electric power industry in Alberta from the perspective of the natural gas industry was presented with special focus on how the power market can be brought back into balance. The issue of what impacts the deregulated power market will have on natural gas consumption or prices was also reviewed. It was noted that deregulation of the electric power industry will have a definite impact on natural gas consumption but no significant impact on prices. It is estimated that in 1999/2000 gas demand will be 90 million cf/day for incremental electricity generation. However, as long as pipe capacity out of the province exits, this increase in natural gas demand in Alberta is not expected to affect gas prices

  11. Whither Alberta's oil production?

    Purvis, R.A.; Dick, A.B.

    1991-01-01

    It is demonstrated how a combination of old theory (decline methods and statistics) and new technology (computer graphics) can enhance decline-curve forecasts for multi-well groupings. Production and well-count forecasts are presented for four different sized groups of aggregate production. The four examples are: the small Manville pool; the Pembina Cardium, Alberta's largest oil pool; an aggregate of all reef pools of Keg River age; and an aggregate of all wells reporting conventional oil production in the province of Alberta. In each case graphical results show the historical and forecast trends for the statistical distribution of well rates, the median well rate, the aggregated rate, and the number of producing wells. It is concluded that well rate distributions for groups ranging from 15 wells in a single pool to thousands of wells in hundreds of pools are all approximately lognormal. Lognormal well rate distributions and Lorenz graphs provide qualitative and quantitative assessments of a resource base. Decline curves for the median well rate can reveal trends masked in the aggregated rate by changing well count, operating practice and degradation of the resource base. The number of producing wells in Alberta has grown from ca 9000 in 1970 to ca 24,000 in 1988, has remained constant from 1988-1990, and will start to decline as the number of suspended or abandoned wells exceeds the number of new completions. 3 refs., 13 figs., 4 figs

  12. Alberta propylene upgrading prospects

    International Nuclear Information System (INIS)

    2000-03-01

    A very significant byproduct recovery and purification scheme is at present being prepared by TransCanada Midstream (TCMS). Alberta Economic Development commissioned an independent study to identify propylene supply options while proceeding with the evaluation of various propylene derivatives with regard to their fit with the Alberta context. Identification of chemical companies with derivative interests was also accomplished. By 2005, it is estimated that 280 kilo-tonnes of propylene will be available on an annual basis from byproduct sources. Those sources are oil sands upgraders, ethylene plants and refineries. The ranges of impurities and supply costs vary between the different sources. An option being considered involves pipeline and rail receipt with a major central treating and distillation facility for the production of polymer grade (PG) propylene with propane and other smaller byproducts. Special consideration was given to three chemicals in this study, namely: polypropylene (PP), acrylonitrile (ACN), and acrylic acid (AA). Above average growth rates were identified for these chemicals: demand is growing at 6 to 7 per cent a year for both PP and ACN, while demand for AA grows at 8 per cent annually. Two other possibilities were identified, propylene oxide (PO) and phenol. The study led to the conclusion that low capital and operating costs and shipping costs to the Pacific Rim represent advantages to the development of propylene derivatives in the future in Alberta. 4 refs., 87 tabs., 7 figs

  13. Alberta royalty structure changes seen lacking

    Anon.

    1992-01-01

    This paper reports that Canadian petroleum companies have welcomed a revamp of Alberta's royalty structure but say it falls short of what is needed to revitalize activity in the province. The changes will give producers a cut in royalties of at least $170 million (Canadian)/year, offer incentives for new drilling, and index royalty levels to prices. The new royalty plan also will reward companies that funnel more capital into increased exploration programs. The industry association the new royalty rates tied to prices could increase royalties if prices rise above $26 (Canadian)/bbl for oil and $1.70 (Canadian)/Mcf for natural gas. Royalty take would decline below these prices. Oil prices currently are near the $26/bbl level. CAPP the it is difficult to assess the effects of the royalty changes in reactivating shut-in wells and increasing production from marginal wells

  14. Alberta`s petroleum industry and the Conservation Board

    Energy Technology Data Exchange (ETDEWEB)

    Breen, D.H.

    1993-12-31

    The history of Alberta`s petroleum industry and Energy Resources Conservation Board (ERCB) was told. The conservation movement in Alberta was tracked from 1908 to the founding of the Petroleum and Natural Gas Conservation Board in 1938. Failure of Alberta`s first proration, and the Turner Valley `waste` gas conservation movement occurred during this period. The Leduc discovery and effects of the new regulatory environment on its development were discussed. The natural gas export debate, and the expansion of Alberta`s crude oil market were recounted in detail. The organization and regulation of field development which occurred during the period from 1948 to 1959 was presented. Past actions of the Petroleum and Natural Gas Conservation Board reviewed from today`s perspective. The petroleum industry and the ERCB were said to have been jointly responsible for the creation of a prosperous and confident new Alberta, moving it further and further away from the Canadian economic and political mainstream,, and reinforcing the sense of alienation that began to develop during the preceding agrarian decades. 53 figs., 48 tabs.

    1985-03-01

    Lower Cretaceous coal-bearing strata exposed in the northern and north-central foothills of Alberta form part of a predominantly nonmarine succession that extends from Montana to northeastern British Columbia. The Luscar Group (revised) forms the sequence of coal bearing Lower Cretaceous strata that disconformably overlies marine and nonmarine strata of the Nikanassin Formation or Minnes Group and disconformably underlies marine shales of the Blackstone or Shaftesbury formations. It includes a thin, basal conglomerate, a predominantly nonmarine sandstone and shale unit that locally contains coal; a marine shale and sandstone unit, and an upper nonmarine sandstone and shale unit that contains thick commercial coal seams. These units form the Cadomin, Gladstone, Moosebar and Gates formations, respectively. The Luscar Group is exposed from Kakwa River to Clearwater River in the Foothills of Alberta. It represents a slight modification, by the inclusion of the thin basal conglomerate, from the previous usage of the term Luscar in the northern Foothills of Alberta. 25 references.

  16. Alberta's electricity forwards market

    International Nuclear Information System (INIS)

    Andrews, D.

    2002-01-01

    This paper outlined how the province of Alberta is starting over with a wholesale electricity market. Wholesalers have retreated back to the real-time market. The Watt-Ex standard market design position paper, issued in October 2002, examines wholesale market issues. The author notes that the biggest constraint to competitive electricity market is the reliance on real-time markets to price a good portion of transactions. Doing so, creates extreme price volatility and ineffective price signals because demand and supply have only a limited ability to respond to prices

    Poultry farming has been touted as one of the major ways by which poverty can be reduced in low-income economies like Ghana. Yet, anecdotally there is a high failure rate among these poultry farms. This current study seeks to understand the relationship between network ties and survival chances...... of small commercial poultry farms (SCPFs). We utilize data from a 2-year network survey of SCPFs in rural Ghana. The survival of these poultry farms are modelled using a lagged probit model of farms that persisted from 2014 into 2015. We find that network ties are important to the survival chances...... but this probability reduces as the number of industry ties increases but moderation with dynamic capability of the firm reverses this trend. Our findings show that not all network ties aid survival and therefore small commercial poultry farmers need to be circumspect in the network ties they cultivate and develop....

  18. Expanding the grid in Alberta

    Horner, M. [AltaLink Management Ltd., Calgary, AB (Canada)

    2010-07-01

    This PowerPoint presentation discussed some of the changes and strategies that are currently being adopted by AltaLink to expand Alberta's electricity grid in relation to wind power development. The company is Alberta's largest transmission facility operator. Wind power currently accounts for approximately 5 percent of the province's generation mix. Applications for new wind farms will increase Alberta's 629 MW of wind power generation capacity to 5530 MW. Alberta's transmission regulation requires that 100 percent of in-merit generation can occur when transmission facilities are in service, and that 95 percent of in-merit generation can occur under abnormal operating conditions. A new transmission line is being constructed in the Pincher Creek and Lethbridge region as part of a southern Alberta transmission reinforcement project. The Alberta Electric System Operator (AESO) and Canadian Wind Energy Association (CanWEA) are working together to ensure that adequate resources are available while system reliability is maintained. The Ardenville wind farm is the first wind power project to be energized under the new connection model launched by the AESO. The connection model was developed to identify, connect, and construct new energy projects. The project will also identify connection routes with the lowest overall impact on the province. Alberta will also continue to implement technologies that ensure the development of a smart grid. tabs., figs.

  19. Sulphur demand growing. [Alberta

    Energy Technology Data Exchange (ETDEWEB)

    1975-01-20

    Sulfur markets look better going into 1975 than they have for several years, as North American demand growth is being filled largely by elemental sulfur producers and overseas. Demand is rising as fast as the capacity of Canadian transportation and handling facilities. It will take a long time to make much of a dent in the total Alberta stockpile of 14 million long tons at the end of 1974, with involuntary production from sour gas plants exceeding sales volume since 1972. However, there is some encouragement in the approaching peakout of production combined with a substantial increase in price since the low point of the cycle at the beginning of 1973, and a predicted rise of at least 20% in domestic (North American) sales this year over 1974.

    2006-12-28

    Recent international and national events have brought critical attention to the Canadian public health system and how prepared the system is to respond to various types of contemporary public health threats. This article describes the study design and methods being used to conduct a systems-level analysis of public health preparedness in the province of Alberta, Canada. The project is being funded under the Health Research Fund, Alberta Heritage Foundation for Medical Research. We use an embedded, multiple-case study design, integrating qualitative and quantitative methods to measure empirically the degree of inter-organizational coordination existing among public health agencies in Alberta, Canada. We situate our measures of inter-organizational network ties within a systems-level framework to assess the relative influence of inter-organizational ties, individual organizational attributes, and institutional environmental features on public health preparedness. The relative contribution of each component is examined for two potential public health threats: pandemic influenza and West Nile virus. The organizational dimensions of public health preparedness depend on a complex mix of individual organizational characteristics, inter-agency relationships, and institutional environmental factors. Our study is designed to discriminate among these different system components and assess the independent influence of each on the other, as well as the overall level of public health preparedness in Alberta. While all agree that competent organizations and functioning networks are important components of public health preparedness, this study is one of the first to use formal network analysis to study the role of inter-agency networks in the development of prepared public health systems.

    Full Text Available We extend the existing enumeration of neck tie-knots to include tie-knots with a textured front, tied with the narrow end of a tie. These tie-knots have gained popularity in recent years, based on reconstructions of a costume detail from The Matrix Reloaded, and are explicitly ruled out in the enumeration by Fink & Mao (2000. We show that the relaxed tie-knot description language that comprehensively describes these extended tie-knot classes is context free. It has a regular sub-language that covers all the knots that originally inspired the work. From the full language, we enumerate 266,682 distinct tie-knots that seem tie-able with a normal neck-tie. Out of these 266,682, we also enumerate 24,882 tie-knots that belong to the regular sub-language.

    This report contains background information, including historical aspects, roles of government agencies, and relevant technical information, for use as a resource document at a conference on water resources in northern Alberta. An overview is presented of the three river basins which are the geographic focus of this report (Peace River, Athabasca, and Beaver River), describing their characteristics, the types of human activity occurring in them, and the relevant issues pertaining to water. The roles and responsibilities of government departments and agencies in water management are then introduced. A section on water resource issues defines ten topic areas, and for each issue, a summary of the issue, background of the issue, and key concerns and suggested actions are given. These issue areas concern groundwater management (including protection from contamination by oil field produced water), community water supply, farmland drainage and erosion, protection of surface water quality, watershed and wetlands management, farm and rural water supply, tourism/recreation and fisheries, industrial water use (particularly by the oil sand, forestry, and hydroelectric power industries), native peoples' concerns, and water diversion. The final section discusses a number of common themes which arose from the public consultation process, including integrated planning and program coordination, monitoring and enforcement, public information, and research requirements. 22 refs., 8 figs., 3 tabs.

  6. Alberta's new oil boom

    International Nuclear Information System (INIS)

    Nikiforuk, A.

    1997-01-01

    A massive expansion of Canada's oil sands and the oil-mining business is underway. The prediction is that within five years there will be at least three, possibly six, huge new open pit mines north of Fort McMurray, Alberta. It was suggested that within 20 years, possibly half of Canada's oil supply will come from the oil sands industry which has already attracted $10 billion worth of developments. Unlike conventional crude, the oil sands contain bitumen, water, clay, minerals and lots of sands. Shallow deposits are mined like coal. Deeper formations make use of in-situ thermal recovery techniques. Extraction costs are presently at $15 per barrel, aiming for $12 by 1999. Return on investment is in double digits. Estimates of reserves in the Athabasca, Cold Lake, Peace River and Wabasca deposits go as high as 1.7 trillion barrels, or about twice as much as Saudi Arabia's conventional crude reserves. Syncrude has built a $5 billion production facility and two pipelines have already been proposed to transport the oil sands crude to midwestern US refineries. US refineries prize synthetic crude as excellent mixing stock. The major problem with oil sands is that unlike conventional oil, these reserves require an enormous amount of energy to exploit, which in turn means lots of foul air and greenhouse gases. There are many environmental unknowns, and without a clear management framework in sight the addition of two or three Syncrude-size operations has the potential to create a real and significant acid rain problem in the Western Canada Basin

    This conference addressed issues dealing with Alberta's restructured electric power industry and new policies from the perspective of Alberta's independent power industry. It covered lessons learned from electric industry restructuring, transmission strategies, transmission frameworks, competitive markets, power costs, energy prices, and power outages. Interconnected power systems between Alberta and British Columbia were also reviewed along with grid reinforcement requirements. Markets and restructuring efforts in other jurisdictions such as Quebec and Maritime Canada were briefly reviewed. The move to deregulate the industry has played an important role in restructuring a vertically integrated industry into power generation, transmission and distribution. High electricity prices eventually resulted in re regulation of the industry and a synergy between wholesale and retail markets. Five of the 17 papers were indexed separately for inclusion in the database. refs., tabs., figs

    This paper reports that China's state oil company has bought a stake in an in situ oilsands research project in northern Alberta. China National Petroleum Corp. (CNPC) will invest $6.5 million in the Underground Test Facility (UTF) operated by Alberta Oilsands Technology and Research Authority (Aostra) near Fort McMurray. It is the first foreign research investment for CNPC. The UTF is a joint venture by provincial agency Aostria, the Canadian federal government, and commercial partners in underground mining techniques to extract crude oil from bitumen. Alberta opened a trade office in Beijing in 1991 and now sells several hundred million dollars a year in petroleum equipment and services to China. A horizontal well in situ steam injection process is approaching the production stage at the UTF. It is to begin producing at a rate of 2,000 b/d this fall. The current project is a followup to a pilot project

    We evaluated the small intestines of 123 gray wolves (Canis lupus) that were collected from Idaho, USA (n=63), and Montana, USA (n=60), between 2006 and 2008 for the tapeworm Echinococcus granulosus. The tapeworm was detected in 39 of 63 wolves (62%) in Idaho, USA, and 38 of 60 wolves (63%) in Montana, USA. The detection of thousands of tapeworms per wolf was a common finding. In Idaho, USA, hydatid cysts, the intermediate form of E. granulosus, were detected in elk (Cervus elaphus), mule deer (Odocoileus hemionus), and a mountain goat (Oreamnos americanus). In Montana, USA, hydatid cysts were detected in elk. To our knowledge, this is the first report of adult E. granulosus in Idaho, USA, or Montana, USA. It is unknown whether the parasite was introduced into Idaho, USA, and southwestern Montana, USA, with the importation of wolves from Alberta, Canada, or British Columbia, Canada, into Yellowstone National Park, Wyoming, USA, and central Idaho, USA, in 1995 and 1996, or whether the parasite has always been present in other carnivore hosts, and wolves became a new definitive host.

    The long term objective of the Oil Sands Business Unit of Alberta Energy is to pave the way for Alberta's bitumen production to reach 3 million barrels per day by 2020. This presentation described the national government's role in resource development. It was emphasized that since the Crown is the owner of the oil sands resource, it would benefit by providing strategic leadership and by generating a larger royalty base. The oil sands fiscal regime was described with reference to generic royalty, risk sharing, investment, and project economics. Business rule principles were also outlined along with criteria for project expansions. Both upstream and downstream challenges and opportunities were listed. 4 figs

  11. Alberta outlook: cash and energy team wins business for Alberta

    The increase in Alberta's gross provincial product over the past decade from $3.9-billion in 1964 to $12-billion last year is largely due to its energy industries. Coal, oil, and gas make up almost all of the 48 percent of the net value of production that comes under the heading of mining. The financial success of the province stems from a happy combination of far-sighted government leadership; the strong tradition of local entrepreneurship; and the interest shown by world financiers in Alberta's energy opportunies. Energy-generated Albertan capital is moving out to seek energy-related opportunities in surrounding areas of the U.S. and Canada. An analysis of the $1.5-billion ethylene complex centered in the Red Deer Area shows that some benefits include ethane extraction, ethylene production, and pipeline products produced for export to improve balance of payments, create new jobs, and produce large revenues for the corporate partners. A tabulation of 57 energy-related projects under construction in Alberta, mid-1975, is given with some financial data. There exists a need for foreign capital, but the Energy Minister of Canada has stated that it is Alberta that will decide what oil, gas, and other energy investments from foreign sources will be acceptable in that province, and what export arrangements can be made. Some specific joint energy developments are discussed, but it is understood that any joint venture will be assessed on a project-by-project basis. (MCW)

    2001-01-01

    Recent and future changes in the Alberta power system configuration has prompted a study by ESBI Alberta Ltd. to review the transfer capability of the existing Alberta to British Columbia power tie for power export and power import. The tie includes one 500 kV and two 138 kV lines. The capability was determined from both voltage and transient security points of view. Several single and double contingencies/disturbances were considered. Voltage security assessments were carried out for twelve cases, of which four were selected for dynamic studies. The studies were based on computer simulations using the Interactive Power Flow Program, Voltage Stability Program, Transient Security Assessment Tool, and Small Signal Analysis Tool. The voltage security studies determined the limits corresponding to both Voltage Magnitude and Voltage Stability criteria, whereas the transient security studies determined the limits corresponding to both frequency and transient stability criteria. The required generation and direct load sheds in export and import situations were also computed. It was determined that pre-contingency low voltages in Calgary could significantly limit exports to BC, particularly during peak loads. The Langdon Static VAr Compensator and other reactive power sources in the area are very important in maintaining the necessary voltages. The eight new generating units that are expected to be in the area before the winter of 2001 can also increase export limits substantially. Transient security studies showed less export limitations during peak loads in Alberta than those of maintaining Calgary area voltages. The under-voltage tripping of the tie at Langdon and Cranbrook is needed for keeping high transient stability limits. It was concluded that the overall maximum export that can be achieved in the near future is between 235 and 910 MW from peak to light load situations in Alberta. 17 tabs., 34 figs

    2013-10-01

    Full Text Available Background: The family migration literature presumes that women are cast into the role of the tied migrant. However, clearly identifying tied migrants is a difficult empirical task since it requires the identification of a counterfactual: Who moved but did not want to? Objective: This research develops a unique methodology to directly identify both tied migrants and tied stayers in order to investigate their frequency and determinants. Methods: Using data from the 1997 through 2009 U.S. Panel Study of Income Dynamics (PSID, propensity score matching is used to match married individuals with comparable single individuals to create counterfactual migration behaviors: who moved but would not have moved had they been single (tied migrants and who did not move but would have moved had they been single (tied stayers. Results: Tied migration is relatively rare and not limited just to women: rates of tied migration are similar for men and women. However, tied staying is both more common than tied migration and equally experienced by men and women. Consistent with the body of empirical evidence, an analysis of the determinants of tied migration and tied staying demonstrates that family migration decisions are imbued with gender. Conclusions: Additional research is warranted to validate the unique methodology developed in this paper and to confirm its results. One line of future research should be to examine the effects of tied staying, along with tied migration, on well-being, union stability, employment, and earnings.

    2010-07-01

    Alberta has excellent wind resources with over 600 MW of wind generation currently operating on the Alberta Interconnected Electric System (AIES) and there continues to be strong interest in wind development. Integration of large-scale wind power, however, is still relatively new and presents new operational opportunities and challenges. The AESO currently has over 7,700 MW in potential wind power development in Alberta in our interconnection queue. The Alberta system peak load is 10, 236 MW with 12,763 MW installed generation capacity and limited interconnection capability to neighboring jurisdictions. The AESO recognizes that it is important, both to system reliability and to the successful development of renewable resources in Alberta, that the impact on power system operations and the obligations of market participants are understood as Alberta reaches higher levels of wind penetration. The paper discusses the current status and future outlook on wind integration in Alberta. (orig.)

  16. The Alberta oil sands story

    Energy Technology Data Exchange (ETDEWEB)

    1974-01-01

    This report serves as a detailed introduction to the Alberta oil sands and their development. It includes a description of the oil sands deposits, an outline of crude bitumen recovery and upgrading processes, the role of Alberta Energy Company in oil sands development, environmental aspects, manpower requirements for oil sands development, research needs, and further oil sands projects. Presently proven recoverable reserves in the oil sands amount to 26.5 billion bbl of synthetic crude. Production from the Syncrude plant (125,000 bbl/d capacity) is expected to begin in 1977, followed by a Shell Canada operation around 1980. The provincial government will participate in the oil sand industry through its joint venture participation in Syncrude and its 50% share in Alberta Energy Company; the latter company participates in related aspects of the Syncrude project, such as pipelines. The result of Alberta's participation in the industry will mean that, directly or indirectly, the province will realize 60% of the total profits. The job creation potential of oil sands projects is estimated to be extensive, with a direct and indirect work force supported by oil sands activities possibly reaching 180,000 persons by the year 2000. Research needs have been identified, particularly in the area of in-situ thermal recovery technology, and the creation of the Alberta Oil Sands Technology and Research Authority has been authorized in order to meet these needs. Although current reserves are sufficient to support 20-30 synthetic crude plants, a number of factors will limit expansion of the industry. 8 figs., 5 tabs.

In New Tech, New Ties, Rich Ling examines how the mobile telephone affects both kinds of interactions......The message of this book is simple: the mobile phone strengthens social bonds among family and friends. With a traditional land-line telephone, we place calls to a location and ask hopefully if someone is "there"; with a mobile phone, we have instant and perpetual access to friends and family......—those mediated by mobile communication and those that are face to face.

    2012-12-01

    Tissue retraction is implicated in the pathogenesis of various ophthalmic disorders. Here we describe the clinical characteristics, epidemiology and pathophysiology of a form of retraction syndrome which - to the best of our knowledge - has not been reported in the ophthalmic literature so far. We have termed this condition - consisting of a slowly progressive pseudovertical shortening of tie length due to a horizontal extension of girth length - the "Tie retraction syndrome" (TRS). Other pathognomonic features include an increased tie tip to belt buckle distance and a prolapse of the subumbilical fat pad (SUFP). The syndrome has a clear male to female preponderance and shows an increasing incidence with age and income before tax. Based on a newly proposed grading scheme we discuss and illustrate the diagnosis as well as the medical and surgical management options of this abundant, but often undiagnosed condition. The authors have no explanation for the apparent lack of awareness for this widely preponderant syndrome and its severe cosmetically disfiguring potential. We thus would like to invite all fellow colleagues with expertise in the field to comment or present their views.

  19. The economics of power generation in Alberta : the pool price impact of Genesee Unit 3

    Topping, D.

    2003-01-01

    Alberta power pool prices for year 2000 were reviewed. The model assumptions were: studies based on PROSYM market simulations; base-load units offered at incremental cost; and, considerations in those cases where system gas units were modeled as coal units. The current situation in Alberta was reviewed. The Genesee 3 coal-fired facility is expected to be completed in the Winter 2004-2005 with an efficiency of 8 to 18 per cent better than other coal units. A graph was shown to examine the expected impact of Genesee 3 on Alberta prices. Electricity prices would increase during the period 2005-2008 without Genesee 3. Alberta prices are affected by factors such as: load-resource balance, fuel prices, cost of new capacity, offer strategy, available transmission, and tie lines. A capacity surplus is expected for the period 2003-2008. In addition, good correlation is expected for pool prices with gas prices. With Genesee 3 in operation, lower pool prices are expected in Alberta. figs

  20. A smart electricity policy for Alberta : enhancing the Alberta advantage

    Pape-Salmon, A.; Hornung, R.; Macintosh, R.; Marr-Laing, T.

    2001-03-01

    The promotion of sustainable energy technologies under a competitive electricity market in Alberta was discussed. The electric power industry in Alberta is currently in a crisis with rising electricity prices. The government has tried to mitigate the impacts by providing large rebates to help ease the financial burden on consumers. The author argued that unless the fundamental causes of the problem are dealt with, Albertans will soon face even larger problems. This paper described a new approach to electricity sector planning in Alberta. In particular, the approach focused on conserving energy and improving energy efficiency as well as on increasing the use of low-impact renewable energy such as small hydro, wind, solar, geothermal, biomass and waste fuel generators and cogenerators. New policies would protect consumers from price and resource instability as well as from human health and environmental degradation. Additional policies would promote diversity in electricity supply and competition. Competition encourages electricity suppliers to work through market based mechanisms instead of government regulation or intervention. Competition in the electricity markets may also lead to increased customer choice, a larger number players in the electricity generation sector, and greater opportunities for trade. Increased competition may force producers to develop cost effective technologies that promote sustainable development to mitigate some environmental impacts. 3 tabs

  1. 1973 : Trudeau tangles with Alberta

    International Nuclear Information System (INIS)

    Anon.

    2008-01-01

    In 1973, the Canadian government took measures to place oil exports under federal control and placed a freeze on oil prices. Prime Minister Pierre Trudeau unveiled plans for a national energy policy that would dissolve the Borden policy which prevented western Canadian crude from accessing the Montreal refining market. Trudeau's policy would extend the oil price freeze and created a one-price national market for Canadian oil. Plans were also underway to create a national oil company that would stimulate exploration and exploitation of new energy resources. The Premier of Alberta was also implementing energy regulations at the same time, aimed at consolidating control of Alberta's own resources within the framework of the Constitution and preventing Ottawa from gaining full control of all of Alberta's energy resources. Other key events in 1973 were the introduction of Saskatchewan's Oil and Gas Conservation, Stabilization and Development Act which gave the province the right to take over the oil rights of all private companies in producing areas. The Polar Gas Project was created to conduct research into building a gas pipeline from the Arctic Islands, and a Canadian Arctic gas study revealed that the Mackenzie Pipeline could be delivering gas by 1977. 1 tab., 1 fig

  2. Facilitating major new generation in Alberta : an overview of the transmission infrastructure requirements

    International Nuclear Information System (INIS)

    2001-01-01

    There has been a growing interest in Alberta over the past year about building new generation. The three main areas under consideration are Fort McMurray, Edmonton, and Southern Alberta. Significant additional generation in these areas would inevitably create demands on the transmission infrastructure, which are examined in this report. It is difficult to predict what generation will be built over the next ten years, especially when several projects have not made it past the conceptual stage yet. Despite this difficulty, it is estimated that 6,500 MW of new generation will be added by 2010, based on the projects already announced and others. At off-peak periods, there would be a surplus capacity of almost 4,000 MW. Substantial upgrading of the transmission system in Alberta will be required if new generation is added, considering that the main transmission grid operates close to its maximum safe transfer limits for some periods. Significant improvements will be required for the transfer of the surplus generation from Fort McMurray to the main load centres of Southern Alberta (2,00 MW by 2010) and the Edmonton- Calgary corridor would also require updates. The estimated cost of these updates is 1.5 billion dollars. A prerequisite for many investors in new generation projects in Alberta is greater access to markets outside the province, and primarily to the western United States. Several options were examined in this report, from additional capacity through British Columbia, to a new route to Washington and Oregon via Montana, and a new route to Nevada and California. Some questions arise, such as whether the transmission infrastructure be built first or vice versa? The cost estimate for the direct line to Arizona/California for the export of 2,000 MW is 1.2 billion dollars. Close cooperation is required between planners and generation developers. 2 tabs., 6 figs

    2012-05-09

    Project Objective: The overarching objective of the Montana Palladium Research Initiative is to perform scientific research on the properties and uses of palladium in the context of the U.S. Department of Energy's Hydrogen, Fuel Cells and Infrastructure Technologies Program. The purpose of the research will be to explore possible palladium as an alternative to platinum in hydrogen-economy applications. To achieve this objective, the Initiatives activities will focus on several cutting-edge research approaches across a range of disciplines, including metallurgy, biomimetics, instrumentation development, and systems analysis. Background: Platinum-group elements (PGEs) play significant roles in processing hydrogen, an element that shows high potential to address this need in the U.S. and the world for inexpensive, reliable, clean energy. Platinum, however, is a very expensive component of current and planned systems, so less-expensive alternatives that have similar physical properties are being sought. To this end, several tasks have been defined under the rubric of the Montana Palladium Research Iniative. This broad swath of activities will allow progress on several fronts. The membrane-related activities of Task 1 employs state-of-the-art and leading-edge technologies to develop new, ceramic-substrate metallic membranes for the production of high-purity hydrogen, and develop techniques for the production of thin, defect-free platinum group element catalytic membranes for energy production and pollution control. The biomimetic work in Task 2 explores the use of substrate-attached hydrogen-producing enzymes and the encapsulation of palladium in virion-based protein coats to determine their utility for distributed hydrogen production. Task 3 work involves developing laser-induced breakdown spectroscopy (LIBS) as a real-time, in situ diagnostic technique to characterize PGEs nanoparticles for process monitoring and control.

    Maxim Power Corporation is a provider of distributed energy and environmental solutions with a total of 55 MW of installed generating capacity in Canada, Europe and Asia, with 35 MW in Alberta. The 8 MW Taber facility in southern Alberta was described. Maxim operates 25 other small scale power generation stations (1 MW units) across 4 sites in southern Alberta. All the sites are interconnected at 25 kV and are eligible for distribution credits. The 3 MW EVI facility which utilizes solution gas was also described in the PowerPoint presentation. Maxim operates an additional 3 projects totaling 10 MW. The paper made reference to issues regarding market attributes for distributed power, policy framework and the transition to a competitive power market in Alberta. The chronology of events in Alberta's power market from August 2000 to June 2001 was outlined. The impacts of deregulation on distributed power include: (1) artificially low price environment from market intervention, (2) high efficiency cogeneration opportunities have been eliminated, (3) business failures and reduced investment, and (4) private investment not afforded the same alternative cost recovery mechanisms as the Alberta balancing pool. The presentation concluded with a report card for Alberta's deregulation, giving a grade F for both present and future opportunities for distributed power in Alberta. 2 figs

    A study was carried out to produce a compendium of electric and magnetic field levels that exist in Canada and to characterize and classify the sources of electric and magnetic fields. Alberta Power's contribution to this project was mainly to measure electric and magnetic fields produced by transmission lines in their service area in Alberta. Ten 240 kV transmission lines, ten 144 kV transmission lines, one 72 kV transmission line, two 25 kV distribution lines, two substations, and one residence were monitored for 60 Hz electric and magnetic field levels. For the 240 kV transmission lines, the electric field ranged from 0.4 kV/m to 1.9 kV/m and the magnetic field from 2.5 milligauss to 27 milligauss at the edge of the right-of-way. For 144 kV lines, the electric and magnetic fields ranged from 0.24-1.00 kV/m and 2.25-12.00 milligauss, respectively, at the edge of the right-of-way. 5 tabs

  9. Why do leaf-tying caterpillars abandon their leaf ties?

    2013-09-01

    Full Text Available Leaf-tying caterpillars act as ecosystem engineers by building shelters between overlapping leaves, which are inhabited by other arthropods. Leaf-tiers have been observed to leave their ties and create new shelters (and thus additional microhabitats, but the ecological factors affecting shelter fidelity are poorly known. For this study, we explored the effects of resource limitation and occupant density on shelter fidelity and assessed the consequences of shelter abandonment. We first quantified the area of leaf material required for a caterpillar to fully develop for two of the most common leaf-tiers that feed on white oak, Quercus alba. On average, Psilocorsis spp. caterpillars consumed 21.65 ± 0.67 cm2 leaf material to complete development. We also measured the area of natural leaf ties found in a Maryland forest, to determine the distribution of resources available to caterpillars in situ. Of 158 natural leaf ties examined, 47% were too small to sustain an average Psilocorsis spp. caterpillar for the entirety of its development. We also manipulated caterpillar densities within experimental ties on potted trees to determine the effects of cohabitants on the likelihood of a caterpillar to leave its tie. We placed 1, 2, or 4 caterpillars in ties of a standard size and monitored the caterpillars twice daily to track their movement. In ties with more than one occupant, caterpillars showed a significantly greater propensity to leave their tie, and left sooner and at a faster rate than those in ties as single occupants. To understand the consequences of leaf tie abandonment, we observed caterpillars searching a tree for a site to build a shelter in the field. This is a risky behavior, as 17% of the caterpillars observed died while searching for a shelter site. Caterpillars that successfully built a shelter traveled 110 ± 20 cm and took 28 ± 7 min to find a suitable site to build a shelter. In conclusion, leaf-tying caterpillars must frequently

  13. Zap... Alberta is jolted by electric deregulation

    International Nuclear Information System (INIS)

    Howe, M.E.

    2001-01-01

    Of all Canadian provinces, Alberta has travelled the furthest along the electric deregulation road. On January 1, 2001, full retail competition came into effect. Wholesale electricity prices are set by the province through an auction process. The bids from purchasers are made through the Power Pool of Alberta against supply offers. Power prices increased from being amongst the lowest in the world to being amongst the highest in North America as a result of deregulation. Changes to the Electric Utilities Act were made recently by the Alberta government to try to mitigate the factors affecting power price increases. RBC Dominion Securities is of the opinion that the changes will not significantly impact the Alberta Pool Price. It is expected that the trend for power price increases to continue, despite some relief from relatively low-cost electricity being felt by other Canadian provinces as a result of the energy crisis in North America. Based on the Electric Competition Unfolds in Alberta report dated June 2, 2001 prepared by RBC Dominion Securities, this document examines the factors at play in electric price increases, assess the sustainability of current power prices in Alberta, and identify Canadian companies believed to be best positioned in the pipeline and gas and electric sectors to benefit from the high power prices in Alberta. Those companies were ATCO, Canadian Utilities, Westcoast Energy and TransCanada PipeLines, and TransAlta. 5 tabs., 5 figs

    International Nuclear Information System (INIS)

    Bott, R.

    1992-11-01

    Background information is presented on the importance of the petroleum industry in Alberta. Alberta holds over 70% of Canada's coal and natural gas reserves and, if bitumen is included, over 90% of Canada's established oil reserves. Alberta's major exports are dominated by crude oil and related products ($9.6 billion in 1990) and the oil and gas sector had $15.7 billion in revenues in 1991, over 4 times as much as the next most important sector, agriculture. About 140,000 Albertans are directly or indirectly employed in the oil and gas industry, about 11% of employed persons. The industry's capital spending in Alberta was $5.3 billion in 1991, and its total expenditures were about $15 billion, and during the 1980s the industry paid about $42 billion to the Alberta government in the form of taxes, royalties, and other fees. Other benefits of the oil and gas industry's presence in Alberta include those related to its employment of a skilled workforce, its advanced research capabilities, and economic spinoff effects from employment and technological development. The influence of recent events on the industry is outlined, including the effects of international energy commodity markets, deregulation, and higher exploration and development costs. The declining financial viability of the Alberta petroleum industry is noted and its future is discussed in the light of such factors as oil prices, markets, new technologies, environmental constraints, and the volume of new discoveries. 9 refs., 5 figs., 1 tab

    Full Text Available This communiqué provides a summary of the production- and consumption-based greenhouse gas emissions accounts for Alberta, as well as their associated trade flows. It is part of a series of communiqués profiling the Canadian provinces and territories.1 In simplest terms, a production-based emissions account measures the quantity of greenhouse gas emissions produced in Alberta. In contrast, a consumption-based emissions account measures the quantity of greenhouse gas emissions generated during the production process for final goods and services that are consumed in Alberta through household purchases, investment by firms and government spending. Trade flows refer to the movement of emissions that are produced in Alberta but which support consumption in a different province, territory or country (and vice versa. For example, emissions associated with the production of Alberta crude oil that is exported to British Columbia for refining and sale as motor gasoline are recorded as a trade flow from Alberta to British Columbia. Moving in the opposite direction, emissions associated with the production of Saskatchewan crops that are exported to Alberta for processing and sale in Alberta grocery stores are recorded as a trade flow from Saskatchewan to Alberta.

    Buch-Hansen, Thomas Cornelius

    2013-01-01

    Masonry cavity walls are loaded by wind pressure and vertical load from upper floors. These loads results in bending moments and compression forces in the ties connecting the outer and the inner wall in a cavity wall. Large cavity walls are furthermore loaded by differential movements from...... the temperature gradient between the outer and the inner wall, which results in critical increase of the bending moments in the ties.

Most of them are iterative, since...... exact instability solutions are complex to derive, not to mention the extra complexity introducing dimensional instability from the temperature gradients.

  19. Alberta's electricity policy framework : competitive, reliable, sustainable

    International Nuclear Information System (INIS)

    2005-01-01

    This paper described public policies in Alberta that are implemented to create an electric power industry that is competitive, reliable and sustainable. The success of Alberta's competitive electric market framework can be attributed to new investment in the industry along with new players participating in the electricity market. The Alberta Department of Energy is committed to a competitive wholesale market model and to competitively-priced electricity. The Alberta Energy and Utilities Board supports the development of Alberta's vast resource base and facilitates power generation development and support through transmission development and an interconnected transmission system. A wholesale market Policy Task Force was established in 2005 to review the progress in Alberta's electric market design and its competitive retail market. This paper outlines a policy framework which addresses design of the regulated rate option post July 1, 2006; short-term adequacy; and long-term adequacy. Other inter-related market issues were also discussed, such as operating reserves market, transmission services, interties, demand response, balancing pool assets, credit, market power mitigation, and wind generation. It is expected that the recommendations in this paper will be implemented as quickly as possible following amendments to regulations or ISO rules. tabs., figs.

    1984-01-01

    A mineral survey of the Spanish Peaks Primitive Area, Montana, disclosed a small low-grade deposit of demonstrated chromite and asbestos resources. The chances for discovery of additional chrome resources are uncertain and the area has little promise for the occurrence of other mineral or energy resources. A reevaluation, sampling at depth, and testing for possible extensions of the Table Mountain asbestos and chromium deposit should be undertaken in the light of recent interpretations regarding its geologic setting.

  1. Senior Managers’ Network Tie Use

    Zarzecka, Olga; Villeseche, Florence

    While the importance or even necessity to build and maintain resourceful social networks appears as a forthright fact, there is still a lack of certainty as to who benefits from the resources that can be accessed through senior managers’ networks, and under what conditions. In this paper, we...... contribute to answering this puzzle with a sample constituted of senior managers from Denmark and their network ties, and investigate both economic and sociological conditions of senior managers’ tie use. Our results show that the greater the distance between aspiration level and actual firm performance......, the more likely it is that senior managers will use their network ties to access resources that benefit chiefly the individual rather than the organization. In addition, we demonstrate that this rapport is moderated by senior managers’ social identity as a member of the corporate elite, so that a strong...

  2. Analysis of ILRS Site Ties

    Science.gov (United States)

    Husson, V. S.; Long, J. L.; Pearlman, M.

    2001-12-01

    By the end of 2000, 94% of ILRS stations had completed station and site information forms (i.e. site logs). These forms contain six types of information. These six categories include site identifiers, contact information, approximate coordinates, system configuration history, system ranging capabilities, and local survey ties. The ILRS Central Bureau, in conjunction with the ILRS Networks and Engineering Working Group, has developed procedures to quality control site log contents. Part of this verification entails data integrity checks of local site ties and is the primary focus of this paper. Local survey ties are critical to the combination of space geodetic network coordinate solutions (i.e. GPS, SLR, VLBI, DORIS) of the International Terrestrial Reference Frame (ITRF). Approximately 90% of active SLR sites are collocated with at least one other space geodetic technique. The process used to verify these SLR ties, at collocated sites, is identical to the approach used in ITRF2000. Local vectors (X, Y, Z) from each ILRS site log are differenced from its corresponding ITRF2000 position vectors (i.e. no transformations). These X, Y, and Z deltas are converted into North, East, and Up. Any deltas, in any component, larger than 5 millimeter is flagged for investigation. In the absence of ITRF2000 SLR positions, CSR positions were used. To further enhance this comparison and to fill gaps in information, local ties contained in site logs from the other space geodetic services (i.e. IGS, IVS, IDS) were used in addition to ITRF2000 ties. Case studies of two collocated sites (McDonald/Ft. Davis and Hartebeeshtoek) will be explored in-depth. Recommendations on how local site surveys should be conducted and how this information should be managed will also be presented.

    We analyze the economic effects of a developer's connectedness in the electronic game industry. Knowledge spillovers between developers are likely to be of special relevance in this knowledge-intensive and regionally concentrated industry. We calculate social network measures for a developer......'s connectedness to other developers at multiple points in time. In a regression in which we exploit within-career variation in social network measures, we find that the number of direct ties a developer has to other developers has a strong effect on both a game's revenues and critics' scores.

  6. Alberta, crisis or opportunity? IPPSA's vision

    International Nuclear Information System (INIS)

    Bachmann, G.

    2001-01-01

    This power point presentation discussed the role of IPPSA and the facts about Alberta's power market, the goal of restructuring and the reality behind it in terms of managing the transition. IPPSA is a non-profit organization to promote a competitive electric marketplace for the benefit of non-regulated power producers and marketers. The role of IPPSA, which has been active in Alberta since deregulation began in 1993, is to ensure that Alberta deregulation protects consumer choice, renewable energy options and competition. IPPSA's environmental concerns involve tax based incentives, national climate change issues and the Kyoto Protocol. Environmental concerns can be addressed through responsible power generation to reduce greenhouse gases through the use of low impact generation sources such as run of river hydro, biomass and wind power. Alberta has also pioneered flare gas generation with currently 50 units in operation. IPPSA believes that in the long-term, Alberta's deregulation program will bring undeniable benefits to the industry and the consumer since competition will eventually create a downward pressure on price and spark innovation and choice. tabs., figs

  7. Alberta's clean energy future

    Energy Technology Data Exchange (ETDEWEB)

    2011-07-01

    This paper deals with the future of clean energy in Alberta. With the present economic growth of the oil sands industry in Alberta, it is expected that there will be very considerable increases in job opportunities and GDP in both Canada and US. The challenges include high-energy demand and reduction of the carbon footprint. Alberta has adopted certain approaches to developing renewable and alternate forms of energy as well as to increasing the efficiency of present energy use and raising environmental consciousness in energy production. Three areas where the effects of clean energy will be felt are energy systems, climate change, and regional impacts, for instance on land, water, and wildlife. Alberta's regulatory process is shown by means of a flow chart. Aspects of oil sands environmental management include greenhouse gas targets, air quality assurance, and water quality monitoring, among others. Steps taken by Alberta to monitor and improve air quality and water management are listed. In conclusion, the paper notes that significant amounts of money are being pumped into research and development for greenhouse gas and water management projects.

    Chandrasekharaiah, M.N.; Dubben, G.; Kolster, B.H.

    1992-01-01

    This paper reports that Alberta gas producers have approved a new contract with California buyers that includes slightly lower wellhead prices and more flexible pricing terms. The 1 year agreement, will apply a flexible price formula to gas sales. A basic volume of 212 MMcfd will receive $1.52 (U.S.)/Mcf. A and S also will buy 200 MMcfd at prices paid for other Alberta gas in the California market. It will have the right to buy added volumes at prices indexed to gas sold into California from the U.S. Southwest. Ballots cast by producers were to be verified by regulatory agencies in Alberta and British Columbia. The more flexible price terms in the new contract are seen as a positive development for negotiations in a dispute over long term contracts

Southern Alberta region was selected based on the authors’ familiarity with the region. Some issues and questions remain to be resolved. Digital formats present a number of challenges in terms of selection and presentation. Legal issues relating to technology such as linking and location information have emerged. Basic technical issues remain, such as, how best to update links.

  11. Alberta Chamber of Resources: 1998 in review

    International Nuclear Information System (INIS)

    Simpson, R.

    1999-01-01

    Several key initiatives taken by the Alberta Chamber of Resources during 1998 are described. Among these initiatives special mention is made of strengthening the relations between the Chamber and the University of Calgary and the University of Alberta through regular contributions to business plan reviews, scholarships, and advisory committees. Working with the Department of Energy on a range of issues involving the environment, taxation, and mineral rights tenure is an area the ACR is involved. Hosting a workshop on the economic and social values and trade-offs in the green areas of Alberta and working with the University Alberta regarding the development of an advisory committee on forest resource valuation is another area. Strategizing the Oil Sands Task Force to strengthen it in the areas of industrial coordination, by-product utilization, the creation niche markets and product quality and investigating, through the Black Oil Pipeline Steering Committee, transportation, technological and marketing issues related to the oil sands are other interests. In the Mineral Sector, the Chamber facilitated discussions towards a Non-Energy Minerals and Mines Act, which among other long-range beneficial effects, prompted the provincial government to provide an additional $ 1.5 million to the Alberta Geological Survey. In the Utilities Sector, the Chamber continued to bring together various parties to work on common challenges and opportunities. Much interest has been generated also on upgraders and research facilitated by the Chamber either with members of the Alberta Research Council, or the National Centre for Upgrading Technology or similar organizations. This kind of facilitation helps the Chamber's member companies to realize cost reductions in development and application of new technologies

  14. Alberta Petroleum Marketing Commission annual report, 1993

    International Nuclear Information System (INIS)

    1994-05-01

    The Alberta Petroleum Marketing Commission has the responsibility of selling the Crown's royalty share of Alberta's crude and synthetic oil production; similar services are provided for natural gas. The Commission also markets crude oil on behalf of producers to North American and offshore consumers. The Commission's position as the largest crude oil marketer in Canada enables it to provide analyses of industry pricing and marketing trends to the Alberta government. 1993 marked the last full year of the Commission operating as Alberta's representative in the energy regulatory arena in Canada and the USA; due to restructuring, these functions will be transferred to the Ministry of Energy in early 1994. A brief overview is presented of crude oil markets in Canada and the USA. The Commission's receipts of light and medium royalty oil totalled 40.2 million bbl, down 11% from 1992, and receipts of heavy crude were 3.7 million bbl, down 42% from 1992. Revenue from crude oil sales was $800 million, down 25% from 1992. The Commission's natural gas activities in 1993 included price determination and information collection. 4 figs., 3 tabs

    1998-01-01

    Alberta's oil sands have been recognized as a major strategic resource in Alberta's and Canada's energy and economic future. The oil sands cover an area of almost 77,000 square kilometres and contain approximately 1.7 trillion barrels of oil, of which 300 billion barrels are believed to be recoverable. Highlights of Alberta production from 1973 to 1997 were reviewed. The review showed that by 1997, production of bitumen and synthetic crude oil from the oil sands reached 520,000 barrels per day which is 33 per cent of Alberta's and 25 per cent of Canada's total liquid petroleum production. Activities in oil sands development were outlined, including land sales, historical capital spending, predicted capital spending, technological improvements, and production and price forecasts. Improvements in oil recovery have been accounted for by technological improvements such as multi-lateral drilling, steam assisted gravity drainage, hydrotransport, and synergies with existing facilities. Since 1993, there has been a sharp increase in oil sands land sales. A total investment of $18.8 billion has been announced for the Athabasca, Cold Lake and Peace River deposits for the near future. Prospects for continuing vigorous development in oil sand extraction was predicted. 1 tab., 9 figs

  16. Alberta industrial synergy CO2 programs initiative

    International Nuclear Information System (INIS)

    Yildirim, E.

    1998-01-01

    The various industrial sectors within Alberta produce about 350,000 tonnes of CO 2 per day. This presentation was concerned with how this large volume and high concentration of CO 2 can be used in industrial and agricultural applications, because every tonne of CO 2 used for such purposes is a tonne that does not end up in the atmosphere. There is a good potential for an industrial synergy between the producers and users of CO 2 . The Alberta Industrial Synergy CO 2 Programs Initiative was established to ultimately achieve a balance between the producers of CO 2 and the users of CO 2 by creating ways to use the massive quantities of CO 2 produced by Alberta's hydrocarbon-based economy. The Alberta CO 2 Research Steering Committee was created to initiate and support CO 2 programs such as: (1) CO 2 use in enhanced oil recovery, (2) creation of a CO 2 production inventory, (3) survey of CO 2 users and potential users, (4) investigation of process issues such as power generation, oil sands and cement manufacturing, and (5) biofixation by plants, (6) other disposal options (e.g. in depleted oil and gas reservoirs, in aquifers, in tailings ponds, in coal beds). The single most important challenge was identified as 'rationalizing the formation of the necessary infrastructure'. Failing to do that will greatly impede efforts directed towards CO 2 utilization

    2009-01-01

    Plans developed by the Alberta Electric System Operator (AESO) have determined that Alberta's electrical transmission system needs to be expanded. However, there are complex issues that must be considered in order to assess the nature and extent of the needed expansion. Various new amendments to the system were proposed in the Alberta government's Bill 50, including the construction of new transmission lines; the installation of a double circuit 500 kV alternating current line between Edmonton and the Gibbons-Redwater region; the construction of a new 240 kV substation in southeast Calgary; and the installation of 2 single circuit 500 kV alternating current lines between Edmonton and Fort McMurray. This study provided a review of the institutional framework instituted by the government's transmission policy and compared the costs and benefits of 2 large capacity high voltage DC (HVDC) transmission lines proposed for the Edmonton-Calgary corridor relative to the various other transmission system amendment suggestions. An evaluation of Alberta's proposed regulatory process under Bill 50 was also conducted. Results of the study indicated that the addition of the HVDC lines is an inefficient response to concerns over adequate supply and reliability. 72 refs., 18 tabs.

  18. Alberta air emissions : trends and projections

    International Nuclear Information System (INIS)

    2008-06-01

    This paper provided a summary of air emissions trends and projections for Alberta. Predicted regional distribution trends and industry sector emissions were presented. Historical and projected emissions included sulfur oxides (SO x ) nitrogen oxide (NO x ), volatile organic compounds (VOCs), and ammonia (NH 3 ). Results of the study indicated that carbon monoxide (CO) emissions were decreasing, while VOCs, NO x , SO x , PM 2.5 and NH 3 levels were increasing. Approximately 9 per cent of ammonia emissions were from point sources, while the majority of PM 2.5 emissions were attributed to unpaved roads and construction operations. Agricultural animal operations accounted for most of the VOC source emissions in the region. Increased development of the oil sands industry is contributing to increases in VOC emissions. Increases in NH 3 were attributed to growth in the agricultural sector and the increasing use of confined feeding operations in the region. Results of the study indicated that greenhouse gas (GHG) emissions in Alberta will keep increasing as a result of Alberta's growing economy. It was concluded that emissions from other industrial sectors are also expected to increase. In 2005, Alberta's total GHG emissions were 233 megatonnes of CO 2 equivalent, of which 168 megatonnes were attributed to industry. Results were presented in both graph and tabular formats. 3 tabs., 25 figs

    A brief introduction of Nexen Chemicals, one of the largest producers of sodium chlorate in the world, was offered, and a map displaying its locations throughout the world was displayed. Nexen is one of Canada's largest independent oil and gas producers, while Nexen Marketing is involved in the marketing of natural gas in North America. In January 2001, the deregulated market opened in Alberta. High natural gas prices, generation shortages, high prices in California and an upcoming provincial election all combined to complicate the situation. A high degree of volatility characterized the market. A chart displaying weekly average Alberta power and gas prices from Jan 2002 to 13 Oct 2002 was shown. In Ontario, the market opened in May 2002, and the demand growth rate was in the 1 to 2 per cent range. The author indicated that approximately 20 per cent of homeowners in Ontario have signed deals with retailers, contrary to Alberta where very few have done so. A similar chart displaying weekly average Ontario power prices was presented. The issues in Ontario are: consistency in policy, increase market transparency, transmission / distribution price flexibility, overall transmission / distribution to industrial consumers high, and increasing costs of the system operator. In Alberta, the issues are: government intent, congestion management issues, and billing settlement errors that continue. The opportunities offered by a deregulated market include process responsiveness which is rewarded, the ability to look in forward prices when prices fit margin requirement, and gives companies the opportunity to participate in the development of the market. Various charts were also displayed to further illustrate the market in both Alberta and Ontario. figs

  1. The BC-Alberta intertie : impact of regulatory change

    International Nuclear Information System (INIS)

    Christian, J.; Hughes, K.

    2004-01-01

    The interconnected electricity system between the provinces of British Columbia (BC) and Alberta was discussed with reference to the Cranbrook-Langdon 500 kV line and two 138 kV transmission lines. The lines in British Columbia are owned by BC Hydro and operated by the BC Transmission Corporation, while the lines in Alberta are owned by AltaLink and operated by the Alberta Electric Systems Operator (AESO). The operating terms and conditions are established by an Interconnection Agreement between all parties. The Alberta-BC Intertie was designed to operate at an operating transfer capacity of 1200 MW from BC to Alberta, and 1000 MW from Alberta to BC. The operational limits on Intertie capacity were imposed due to voltage constraints within Alberta during high load periods resulting from insufficient transmission support. It was noted that available capacity is often under-utilized because sometimes it is not economical to schedule into or out of Alberta due to better market conditions in the Pacific Northwest. Transmission users in BC have explicit transmission rights which must be purchased on an hourly basis. However, transmission rights in Alberta follow dispatch of generation through Power Pool bidding. The impact of an under-utilized transmission capacity is higher wholesale prices in both Alberta and in the Pacific Northwest because ratepayers end up paying for the under-used capacity. This presentation also outlined regulatory change in Alberta with reference to consolidation of Alberta's Transmission Administrator, Power Pool Administrator and system controller functions; Alberta's new transmission policy; and, the enhanced role of market surveillance administrator. It also outlined the regulatory change in British Columbia with reference to the creation of the BC Transmission Corporation; the Heritage Contract; and, stepped rates and retail access. The effect of changes on intertie usage in both Alberta and British Columbia were also outlined. 31 refs

    1993-01-01

    Petroleos del Peru predicts a 10% increase in Peru's oil production this year and a further increase in 1994. Petroperu also forecasts a sharp increase in drilling in Peru this year. After several years of declining oil production, a gradual turnaround in the cash strapped country's petroleum industry is largely tied to its progress in privatization. The government last year began a campaign to privatize all state owned companies by the end of July 1995. The paper discusses forecasts by Petroperu; the contract of Occidental del Amazonas Inc.; the Petromar privatization; Great Western's contract; development of the Aguaytia gas field; and refinery contracts

    The 18 presentations at this conference covered a wide range of topics dealing with the Canada's electric power industry. Issues of particular concern included lessons learned from restructuring in Alberta, Ontario and New Brunswick, as well as credit risk management in the power sector, power marketing in Alberta, and transmission issues. The challenges facing the industry regarding climate change and the commitment made by Canada under the Kyoto Protocol to reduce greenhouse gas emissions was also discussed with particular reference to emissions trading and the need to harmonize environmental policies between federal and provincial jurisdictions. The move to deregulate the industry played an important role in restructuring a vertically integrated industry into power generation, transmission and distribution. High electricity prices eventually resulted in re regulation of the industry and a synergy between wholesale and retail markets. Four of the 18 papers were indexed separately for inclusion in the database. refs., tabs., figs

    An overview of the current and future North American supply and demand and trends for natural gas liquids (NGLs) is presented. The current Alberta straddle plant configuration, the NGL pipeline system and product flow, and the profitability of straddle plants are described. The driving forces to increase Alberta's straddle plant capacity are also reviewed. These include: (1) increased gas production, (2) increased demand for ethane, (3) control of produced NGLs, and (4) the desire to maintain a competitive position. Highlights of the Centurion Project designed to meet the needs of Dow Chemicals and the producers by providing long-term ethane supply and physical access to a more liquid NGL market, the project's current status and 'next steps' were also summarized. tabs., figs

    This document provided an overview of ambient air pollutant trends in Alberta. The report discussed the following pollutants having effect on human and environmental health: carbon monoxide (CO), hydrogen sulphide (H2 S ), nitrogen dioxide (NO 2 ), sulphur dioxide (SO 2 ), ozone (O 3 ), fine particulate matter (PM 2 .5), benzene, and benzopyrene. Each of these pollutants was described. The report provided data on annual average concentration trends and annual 99th percentile concentration as an indicator of peak concentrations. A map illustrating air quality monitoring stations in 2006 was also provided. The findings revealed that mean annual CO levels were the lowest they have been since 1990; hydrogen sulphide concentrations have fluctuated in time since 1990; most Edmonton and Calgary area stations showed significant decreasing trends in annual average NO 2 levels since 1990; and higher SO 2 concentrations have been found in the industrial areas of Alberta, such as the Redwater and Scotford oil sands locations. tabs., figs

  8. Transmission : key to the Alberta market

    International Nuclear Information System (INIS)

    Lyons, D.

    2003-01-01

    AltaLink is Canada's first independent transmission company with 11,000 kilometres (km) of lines and 250 substations. It possesses a unique ownership structure with strong technical partners and financial capability. No major transmission system has been built in the last fifteen years in Alberta. The author examined the situation of power transmission in Alberta, indicating that developments should include capacity increase out of Fort McMurray, and better market integration with both British Columbia and the Pacific Northwest. An efficient and effective market requires ample transmission capacity, which would allow for trade and competition, access for efficient generators, and access to regional markets. New transmission must be planned and achieved in a proactive manner. Generation developers must be assured that transmission will be available, and that tariffs and loss factors will be predictable and stable. figs

    Thomas, A.

    1995-01-01

    Operations of the Alberta Energy Company's (AEC) Suffield properties in southern Alberta, the company's major production area, were reviewed. With a staff of just over 100, Suffield was said to produce an average of 180 million cubic feet of natural gas and more than 4100 barrels of oil per day. Suffield's remaining reserves were estimated to be 814 billion cubic feet of gas and 6.4 million barrels of oil. The field was expected to be in production for the next 20 years. A master plan to minimize normal field decline and control operating costs at Suffield was developed by AEC. Cloning gas storage plants was one of the methods used by for cost control. Designing and constructing identical gas plants was another means of producing major savings, especially in areas such as equipment purchase, and construction

    The growing Asian interest in Alberta's oil sands and import opportunities was discussed along with the feasibility of marketing bitumen to Asia. Asia is an obvious new market for Canadian heavy oil and bitumen due to an increasing demand for petroleum products in Japan, Korea, Taiwan and China. This paper examined the following three criteria that will determine the success of any initiative to move Canadian crude oil to Asian-Pacific markets: (1) a sustainable supply from Alberta; a pipeline to transport the crude to a deepwater port on the west coast; and, a guaranteed market at the other end. The basis for Asian interest in Alberta's oil sands is the sustainable secure supply of oil for growing Asian markets; heavy dependence on supplies from the Middle East; the desire to diversify supply sources; and, opportunities to invest in oil sands developments. Examples of Asian (Japan, Korea, Taiwan and China) missions to Alberta were presented along with the challenges of getting products to market with reference to Enbridge's new market access plan, Terasen's staged capacity expansion for heavy crudes and refined products, and sea transport from Prince Rupert. The paper also included graphs depicting world GDP; incremental increase in world primary energy demand by fuel for 2000 to 2020; world oil demand by region; oil demand by region in Asia; oil demand and supply in northeast Asia (Japan, China, Korea) and dependence level on Middle Eastern oil; oil demand and supply in China; China's petroleum production and consumption; refined products market forecast for 2000 to 2020; 2002 crude oil imports to Asia; 2004 refining capacity; product quality comparisons; cost competitive study; and energy policy objectives for China, Japan, Korea and Taiwan. 19 figs

    Open pit mining and in situ techniques, such as steam stimulation, are used to recover Alberta's bitumen and heavy oil resources, which have higher viscosities than conventional hydrocarbons. The bitumen is typically upgraded to synthetic crude oil (SCO). In the simplest processing scheme, the bitumen is blended with diluent for ease in pipeline transport and then processed at refineries with upgrading facilities. The bitumen is also upgraded to light SCO at world-scale upgraders in Alberta. The SCO is then processed at refineries in downstream markets. The 2 categories of upgrading, notably primary and secondary upgrading, were described in this article along with technology options for both categories. Slurry hydrocracking is regarded as the most interesting emerging residual fuel upgrading technology. It combines special catalyst mixes with the latest slurry reactor designs as well as innovative catalyst capture and recycle schemes to produce very high conversions and potentially superior upgrading economics. The increase in volume and rate of SCO from Alberta provides refiners in the oil sands marketing sector an unprecedented choice of opportunities to improve profitability. Key trends indicate that production will increase substantially from 2008 to 2030. 5 figs

    The Alberta Petroleum Marketing Commission has the responsibility of selling the Crown's royalty share of Alberta's crude and synthetic oil production; similar services are provided for natural gas. The Commission also markets crude oil on behalf of producers to North American and offshore consumers. The Commission's position as the largest crude oil marketeer in Canada enables it to provide analyses of industry pricing and marketing trends to the Alberta government. 1992 marked the end of chronically depressed natural gas prices and a significant reduction in natural gas surpluses. A brief overview is presented of crude oil markets in Canada and the USA. The Commission's receipts of light and medium royalty oil totalled 45.3 million bbl, unchanged from 1991, and receipts of heavy crude were 6.3 million bbl, up 4% from 1991. Revenue from crude oil sales was $1.1 billion, down from $1.64 billion in 1991.

The Commission also markets crude oil on behalf of producers to North American and offshore consumers. The Commission's position as the largest crude oil marketeer in Canada enables it to provide analyses of industry pricing and marketing trends to the Alberta government. In 1991, the middle east crisis caused prices to spike at the commencement of the Gulf war, but these quickly stabilized. The Commission's receipts of light and medium royalty oil totalled 45.3 million bbl, down 1.5% from 1990, and receipts of heavy crude were 6.1 million bbl, up 5% from 1990. Revenue from crude oil sales was $1,642,244,000, down from $2,078,197,000 in 1990. Loss of the Montreal market through pipeline closure led to increased pressure on prices, particularly on heavy crudes.

    This paper provides a 15 month assessment of Alberta's new competitive electricity market. It also presents lessons that Ontario customers could learn from Alberta's experience. The goal for restructuring is to achieve lower electricity prices, competitive retail markets, increased flexibility of contracts, and to remove investment risks from consumers. Alberta's restructured market includes power generation, high voltage transmission, low voltage transmission and retail sales. Economists agree that deregulation has brought lower prices and other consumer benefits despite some imperfections. After one year, prices in Alberta have gone down from $130/MWh to $30/MWh. Power supply has increased along with demand response, market competitiveness, liquidity, and thermal and economic efficiency. In 2001, Alberta was a net exporter of electricity. In 2001, it was ranked by the Center for Advancement of Energy Markets (CAEM) which ranks states and provinces by 22 attributes for how they are restructuring their power markets. Alberta ranked first overall in North America. Ontario ranked sixteenth. 4 tabs., 5 figs

We conclude that social ties support labor market access for migrant inventors and determine regional choices while dependence on these ties is substantially......We study the impact of social ties on the migration of inventors from East to West Germany, using the fall of the Iron Curtain and German reunification as a natural experiment. We identify East German inventors via their patenting track records prior to 1990 and their social security records...... in the German labor market after reunification. Modeling inventor migration to West German regions after 1990, we find that Western regions with stronger historically determined social ties across the former East-West border attracted more inventors after the fall of the Iron Curtain than regions without...

    Alberta's abolition in 2008 of its health regions and the creation of Alberta Health Services (AHS) was a bold move, but the reasons for the change remain hazy. The stated goals were to "help make Alberta's … system more effective and efficient" and to "provide equitable access to health services and long-term sustainability." Data show, however, that Alberta's health regions were already performing well on these goals relative to other provinces, and where changes have since occurred, they cannot necessarily be attributed to AHS.

    Within the Dubois Quadrangle (Idaho and Montana), environments favorable for uranium deposits, based on National Uranium Resource Evaluation criteria, occur in the McGowan Creek Formation and within some Tertiary sedimentary basins. The Mississippian McGowan Creek Formation consists of uraniferous, black, siliceous mudstone and chert with minor porous sedimentary channels. In the southern Beaverhead Mountains it has been fractured by a bedding-plane fault, and uranium has been further concentrated by circulating groundwater in the porous channels and brecciated zones, both of which contain about 200 ppM uranium. The northern parts of the Pahsimeroi River, Lemhi River, Medicine Lodge Creek, Horse Prairie, and Sage Creek Basins are considered favorable for sandstone-type uranium deposits. Evidence present includes suitable source rocks such as rhyolitic flow breccia, laharic deposits, or strongly welded tuffs; permeable sediments, including most sandstones and conglomerates, providing they do not contain devitrified glass; suitable reductants such as lignite, pyrite, or low-Eh geothermal water; and uranium occurrences

    All geologic conditions in the Dillon quadrangle (Montana and Idaho) have been thoroughly examined, and, using National Uranium Resource Evaluation criteria, environments are favorable for uranium deposits along fractured zones of Precambrian Y metasediments, in the McGowan Creek Formation, and in some Tertiary sedimentary basins. A 9-m-wide quartz-bearing fractured zone in Precambrian Y quartzites near Gibbonsville contains 175 ppM uranium, probably derived from formerly overlying Challis Volcanics by supergene processes. The Mississippian McGowan Creek Formation consists of uraniferous, black, siliceous mudstone and chert. In the Melrose district it has been fractured by a low-angle fault, and uranium has been further concentrated by circulating ground water in the 2- to 6-m-thick brecciated zones that in outcrop contain 90 to 170 ppM uranium. The Wise River, northern Divide Creek, Jefferson River, Salmon River, Horse Prairie, Beaverhead River, and upper Ruby River Basins are considered favorable for uranium deposits in sandstone. Present are suitable uraniferous source rocks such as the Boulder batholith, rhyolitic flow breccia, laharic deposits, or strongly welded tuffs; permeable sediments, including most sandstones and conglomerates, providing they do not contain devitrified glass; suitable reductants such as lignite, pyrite, or low-Eh geothermal water; and uranium occurrences

  1. The Alberta Electrical Grid: What to Expect in the Next Few Years in Alberta

    Directory of Open Access Journals (Sweden)

    Brian Livingston

    2018-04-01

    Full Text Available The Alberta government has stated that it wants to make significant changes to the supply of electricity to the current electrical grid for the province. These changes include the phasing out of coal generation by 2030, the supply of 30 per cent of electricity from renewables by 2030 and the introduction of a socalled capacity market in addition to the current electrical energy market. The achievement of these objectives will require a number of fundamental changes to the existing electrical grid. This paper provides an overall description of these changes. The paper first examines the current grid structure in which coal and gas provide the base load supply in the amount of 90 per cent of electricity demand, and renewables are a relatively small source of supply for the remaining 10 per cent. It then reviews the current simple energy market in Alberta that uses a single price auction to determine the wholesale price of electricity. The paper then notes that the achievement of these changes will require a large amount of investment in the next 15 years to create new generating capacity that currently does not exist. The Alberta Electric System Operator (AESO has forecast that by 2032, Alberta will need an additional 7,000 megawatts of gas generation, 5,000 megawatts of wind, 700 megawatts of solar and 350 megawatts of hydro. To put this in context, the Ontario grid currently has 4,213 megawatts of wind (11 per cent of total generating capacity and 380 megawatts of solar (one per cent of generating capacity. The Alberta government has made two fundamental changes in the electricity market to make this happen. First, it has introduced a Renewable Energy Program (REP to incent investment in renewables. They asked industry to bid on a 20 year contract for supply of electricity that offered a guaranteed fixed price that was independent of the existing wholesale market. The first round of bidding (REP 1 announced in December 2017 resulted in 600

    Air quality and its effects on the environment and human health have received considerable attention during the last three decades in Alberta, Canada. Among the issues receiving a high priority are acid deposition, smog and global warming. There are various sources of emissions to Alberta`s atmosphere, many of which relate to the extraction, processing, and burning of fossil fuels; pulp and paper manufacture; and transportation. There are also natural sources of contaminants, such as particulates from forest fires and methane from bogs. The extraction, processing and combustion of fossil fuels play an important role in Alberta`s economy. The province produces over 80 % of the oil and natural gas in Canada, and nearly half the coal. Low sulphur coal is used in power plants to supply more than 90 % of the electricity used in this province by nearly three million people. As a result, Alberta is responsible for about 27 % of the CO{sub 2}, 23 % of the nitrogen oxides, and 16 % of the SO{sub 2} emissions generated in Canada. Alberta`s air quality is monitored by the Government of Alberta at nine continuous, eight intermittent, over 250 static, and 12 precipitation monitoring stations. Parameters such as carbon monoxide, oxides of nitrogen, sulphur dioxide, particulates, and ion-content of precipitation are measured. Industry operates a large number of ambient and static SO{sub 2} and H{sub 2}S monitoring stations across Alberta, with monitoring costs estimated at 56-80 million USD annually. The unique features of the Clean Air Strategy for Alberta (CASA) have already been published elsewhere. This presentation discusses the mechanism and progress on its implementation. (author)

  5. Looming labour shortages challenge Alberta resource industries

    Energy Technology Data Exchange (ETDEWEB)

    Simpson, R.

    2005-07-01

    The shortage of skilled manpower that is threatening the viability of Alberta's resource industry is discussed. According to statistics compiled by the Canadian Resource Development the Canadian labour force grew by about 226,000 per year during the last quarter century; this will be reduced by about 125,000 per year during the current decade. It is forecast that by 2016, the annul growth will be near zero. To make up for this unprecedented shortfall, the annual rate of immigration required would have to be as high as 650,000 per year. The Alberta Chamber's Workforce Development Committee is aware of the urgency of the situation and is attempting to aggressively investigate the causes of the shortage of skilled labour and finding ways to deal with the problem. Current investigation appears to point the finger at the state of post-secondary education, most particularly the significantly higher underemployment among aboriginal youth and the likelihood that skills programs training developed to encourage First Nation's people would be the most effective way to help easing the growing labour shortage. Too few educational placement for students, a lack of adequate training equipment and financial resources in post-secondary institutions, and the variations in the quality of provincial educational standards receive the most blame, combined with a lack of awareness of employment opportunities or training programs, and the inability to migrate to high opportunity employment areas. A notable program addressing this issue is the Alberta Apprenticeship and Industry Training System which helps young people to start their apprenticeship training while still in high school, and encourage them to continue their training after graduation from high school. The federal government and other groups also encourage participation among Ab originals and work towards eliminating some of the underlying factors of labour shortages, including cultural biases, barriers to inter

  9. Montana BioDiesel Initiative

    2017-01-29

    This initiative funding helped put Montana State University (MSU) in a position to help lead in the development of biodiesel production strategies. Recent shortages in electrical power and rising gasoline prices have focused much attention on the development of alternative energy sources that will end our dependence on fossil fuels. In addition, as the concern for environmental impact of utilizing fossil fuels increases, effective strategies must be implemented to reduce emissions or the increased regulations imposed on fossil fuel production will cause economic barriers for their use to continue to increase. Biodiesel has been repeatedly promoted as a more environmentally sound and renewable source of fuel and may prove to be a highly viable solution to provide, at the least, a proportion of our energy needs. Currently there are both practical and economic barriers to the implementation of alternative energy however the advent of these technologies is inevitable. Since many of the same strategies for the storage, transport, and utilization of biodiesel are common with that of fossil fuels, the practical barriers for biodiesel are comparatively minimal. Strategies were developed to harness the CO2 as feedstock to support the growth of biodiesel producing algae. The initiative funding led to the successful funding of highly rated projects in competitive national grant programs in the National Science Foundation and the Department of Energy. This funding put MSU in a key position to develop technologies to utilize the CO2 rich emissions produced in fossil fuel utilization and assembled world experts concerning the growth characteristics of photosynthetic microorganisms capable of producing biodiesel.

  17. Analyzing negative ties in social networks

    Directory of Open Access Journals (Sweden)

    Mankirat Kaur

    2016-03-01

    Full Text Available Online social networks are a source of sharing information and maintaining personal contacts with other people through social interactions and thus forming virtual communities online. Social networks are crowded with positive and negative relations. Positive relations are formed by support, endorsement and friendship and thus, create a network of well-connected users whereas negative relations are a result of opposition, distrust and avoidance creating disconnected networks. Due to increase in illegal activities such as masquerading, conspiring and creating fake profiles on online social networks, exploring and analyzing these negative activities becomes the need of hour. Usually negative ties are treated in same way as positive ties in many theories such as balance theory and blockmodeling analysis. But the standard concepts of social network analysis do not yield same results in respect of each tie. This paper presents a survey on analyzing negative ties in social networks through various types of network analysis techniques that are used for examining ties such as status, centrality and power measures. Due to the difference in characteristics of flow in positive and negative tie networks some of these measures are not applicable on negative ties. This paper also discusses new methods that have been developed specifically for analyzing negative ties such as negative degree, and h∗ measure along with the measures based on mixture of positive and negative ties. The different types of social network analysis approaches have been reviewed and compared to determine the best approach that can appropriately identify the negative ties in online networks. It has been analyzed that only few measures such as Degree and PN centrality are applicable for identifying outsiders in network. For applicability in online networks, the performance of PN measure needs to be verified and further, new measures should be developed based upon negative clique concept.

  4. Vision 20/20 : saving for the future Alberta advantage

    International Nuclear Information System (INIS)

    Milke, M.

    2006-03-01

    As part of the Alberta Vision 20/20 project, Alberta's past and present spending patterns on natural resources and choices for the future were examined. Trust funds in Alberta, Alaska, and Norway were also compared, in order to learn from other jurisdictions. This report presented findings from Phase 3 of Vision 2020. The objectives of the study were to provide insight on what Alberta's economic, social and policy landscape might look like in the coming decades given expected demographic changes; benchmark Alberta's performance on key economic and social indicators and analyze government performance in related policy areas; supply useful, accessible information and possible solutions to Albertans about some of the challenges that demographic change is likely to bring; encourage discussion of issues among Albertans, including legislators and the media; and, where appropriate, encourage actions to mitigate or alleviate foreseeable problems. The guiding principles of the Vision 20/20 were first presented. Alberta's fiscal context and labyrinth of savings funds were examined. A detailed explanation and literature review of resource trust funds in Norway, Alaska, and Alberta were then provided followed by a comparison of the Alberta, Alaska, and Norway funds. Last, the report presented Alberta's options and discussion as well as recommendations. It was recommended that Alberta's annual per capita spending should not exceed population growth and inflation; the province should consider transfers of additional resource revenue into the Heritage Fund in the manner of the state of Alaska; and the province should deposit between 30 per cent and 40 per cent of all nonrenewable resource revenues in the Heritage Fund annually. 38 refs., 4 tabs., 17 figs., 4 appendices

  5. Groundwater and underground coal gasification in Alberta

    Haluszka, A.; MacMillan, G.; Maev, S.

    2010-01-01

    Underground coal gasification has potential in Alberta. This presentation provided background information on underground coal gasification and discussed groundwater and the Laurus Energy demonstration project. A multi-disciplined approach to project assessment was described with particular reference to geologic and hydrogeologic setting; geologic mapping; and a hydrogeologic numerical model. Underground coal gasification involves the conversion of coal into synthesis gas or syngas. It can be applied to mined coal at the surface or applied to non-mined coal seams using injection and production wells. Underground coal gasification can effect groundwater as the rate of water influx into the coal seams influences the quality and composition of the syngas. Byproducts created include heat as well as water with dissolved concentrations of ammonia, phenols, salts, polyaromatic hydrocarbons, and liquid organic products from the pyrolysis of coal. A process overview of underground coal gasification was also illustrated. It was concluded that underground coal gasification has the potential in Alberta and risks to groundwater could be minimized by a properly designed project. refs., figs.

  6. Positive year for Alberta power pool

    International Nuclear Information System (INIS)

    Reid-Carlson, D.

    1997-01-01

    The electricity power pool in Alberta completed its first year under deregulation. Results to date indicate that the competitive market has operated as intended. The effects of electricity pricing on the oil industry following deregulation were described, given the fact that electricity prices represent the second largest cost item to the oil industry after labour. The peculiarities of the mechanism of electricity pricing (based on hourly matching of supply offers to demand bids) were explained, highlighting the opportunities and risks to the oil industry caused by the hourly price variations and the difficulties involved in accurately forecasting on-peak and off-peak prices a full year in advance. In 1996 predicted average price was $14 to $17/MWh. The actual average price was $13.40/MWh. The general conclusion was that Alberta continues to have a surplus of electricity generation and is well positioned to to take advantage of its low generating costs, at least over the longer term. Short term bidding practices, however, may results in slightly higher system marginal prices

  7. The Alberta smoke plume observation study

    Full Text Available A field project was conducted to observe and measure smoke plumes from wildland fires in Alberta. This study used handheld inclinometer measurements and photos taken at lookout towers in the province. Observations of 222 plumes were collected from 21 lookout towers over a 6-year period from 2010 to 2015. Observers reported the equilibrium and maximum plume heights based on the plumes' final levelling heights and the maximum lofting heights, respectively. Observations were tabulated at the end of each year and matched to reported fires. Fire sizes at assessment times and forest fuel types were reported by the province. Fire weather conditions were obtained from the Canadian Wildland Fire Information System (CWFIS. Assessed fire sizes were adjusted to the appropriate size at plume observation time using elliptical fire-growth projections. Though a logical method to collect plume observations in principle, many unanticipated issues were uncovered as the project developed. Instrument limitations and environmental conditions presented challenges to the investigators, whereas human error and the subjectivity of observations affected data quality. Despite these problems, the data set showed that responses to fire behaviour conditions were consistent with the physical processes leading to plume rise.

  9. Alberta's transmission development policy : review and recommendations

    International Nuclear Information System (INIS)

    Stubbings, R.V.

    2004-01-01

    Alberta's Department of Energy (ADOE) released a policy paper in November 2003 regarding power transmission development for the province. The transmission development policy (TDP) is intended to promote economic growth in Alberta while ensuring consumers with reliable, reasonably priced electricity. This presentation reviewed the main features of the policy and then focused on the allocation of costs to generation customers. The author argued that the proposed changes would result in a sub-optimal development of generation and higher total electricity bills for consumers. He argued that the policy will spare generation customers of any obligation to pay wire-related costs other than local interconnection costs. This would weaken a long-standing ADOE policy which requires generators to pay costs that depend on their location on the transmission system. With the new proposal, generators would not be responsible for ancillary service costs even when they provide direct benefits, and they would pay for system losses on a zonal basis. The author recommended that location charges should be large enough to influence the siting decisions of generators. He also recommended that generators should pay their fare share of transmission use-of-system charges, including ancillary services that provide benefits to generators in the form of a stable, reliable transmission system. 2 tabs., 2 figs

  13. Deregulation and the Alberta experience : the implications for Ontario

    International Nuclear Information System (INIS)

    Desrochers, J.P.

    2002-01-01

    An overview of the first year of electric power industry deregulation in Alberta was presented. The way in which electricity is bought and sold in Ontario and throughout North America is changing. Costs are no longer fixed and regulated. Electricity is becoming a commodity with high levels of price volatility. The paper presented hedging options for Alberta consumers, contracting lessons, market issues and lessons for Ontario. A comparison of Alberta's deregulation schedule with that of Ontario's was included. One year after market opening in Alberta, power prices have dropped significantly. There is a greater than expected demand side response, increased development in power generation, and a decrease in natural gas prices. Issues that still need to be addressed in Alberta include billing and load settlement issues, invoicing/billing standards, the lack of competition at the retail level, and future balancing of pool charges. Energy Advantage Inc. (EA) does not foresee the same drastic increase in price as seen in Alberta market opening, but suggests that uncertainty and volatility will exist in Ontario. In Alberta, customers who did nothing and stayed on default were the ones who benefited, but took a great risk. EA suggests that customers must understand how and when they use electricity, how much is used during on- and off-peak hours, and in the summer versus the winter. When electricity is priced hourly, it is important to know consumption patterns. 7 figs

  14. Alberta Advisory Council on Electricity report to the Alberta Minister of Energy

    International Nuclear Information System (INIS)

    2002-06-01

    This report presents the deliberations of the Alberta Advisory Council on Electricity regarding the restructuring of the electric power industry in the province of Alberta. Strategic issues affecting restructuring over the long term were considered with particular attention to small consumers. The long term vision (Vision 2012) for electric power restructuring is to promote efficient and competitive markets attracting investment and innovation that will result in fair and equitable prices for consumers. It was noted that while the restructuring system is currently in place, progress has not been even across the system. It is expected that it will take several years before a restructured electricity industry is fully functioning. Recommendations were presented to establish a plan to address issues regarding restructuring within power generation, transmission, distribution and export/import policies. The issue of market power, competitiveness and consumer education was also discussed. It was also noted that there are many external forces that impact the electricity system, many of which come from outside Alberta. These include fluctuations in gas prices, electricity demand, changes in the United States, regulatory decisions in other jurisdictions and unexpected business events. It was emphasized that a strong, liquid and competitive wholesale market is vital to achieving Vision 2012. Key factors for a competitive wholesale market include adequate generation, transmission capability and export/import capacity. The report presents the following 3 scenarios: business as usual, managed transition, and freedom 2012. A review of restructuring in several other jurisdictions around the world was also provided. 1 tab., 1 fig

    A countertrade contract ties an export to an import. Usually, countertrade is seen as a form of bilateralism and reciprocity and thus as an inefficient form of international exchange. In this paper we argue that there are circumstances where the tying of two technologically unrelated trade flows may be efficiency enhancing. We show that countertrade can be seen as an efficient institution that solves moral hazard problems and restores creditworthiness of countries with large outstanding debt....

  18. Application of TIE's in assessing toxicity associated with oil sands process waters

    International Nuclear Information System (INIS)

    MacKinnon, M.

    1998-01-01

    The hot water digestion process which separates bitumen from oil sands produces large volumes of process-affected waters which are extremely toxic to aquatic organisms. At Syncrude Canada's northeastern Alberta plant, the toxic waters are contained on the site and none are discharged. Organic acids, hydrocarbons and salts are leached into the tailings waters. A toxicity identification evaluation (TIE) test was used to confirm the main contributors to the acute toxicity in these waters. A battery bioassay approach as well as field and laboratory testing was used to understand the source, pathway and duration of the toxicity. Bioassays helped in developing ways in which to mitigate toxicity issues in both reclamation and operational waters. It was demonstrated that natural bioremediation of process-affected waters can reduce acute and chronic toxicity. The long term reclamation impacts of these waters has yet to be determined

    International Nuclear Information System (INIS)

    1991-05-01

    The Western Area Power Administration (Western), an agency of the United States Department of Energy, is proposing to construct the 115-kV Wolf Point Substation near Wolf Point in Roosevelt County, Montana (Figure 1). As part of the construction project, Western's existing Wolf Point Substation would be taken out of service. The existing 115-kV Wolf Point Substation is located approximately 3 miles west of Wolf Point, Montana (Figure 2). The substation was constructed in 1949. The existing Wolf Point Substation serves as a ''Switching Station'' for the 115-kV transmission in the region. The need for substation improvements is based on operational and reliability issues. For this environmental assessment (EA), the environmental review of the proposed project took into account the removal of the old Wolf Point Substation, rerouting of the five Western lines and four lines from the Cooperatives and Montana-Dakota Utilities Company, and the new road into the proposed substation. Reference to the new proposed Wolf Point Substation in the EA includes these facilities as well as the old substation site. The environmental review looked at the impacts to all resource areas in the Wolf Point area. 7 refs., 6 figs

    1996-01-01

    Finite element models were developed and analyses performed for the tie plate, inner tie block assembly, and corner tie block assembly of a 25 port fuel rack assembly designed for installation in Pool 1 of Building 666 at the Idaho Chemical Processing Plant. These models were specifically developed to investigate the adequacy of certain welds joining components of the fuel storage rack assembly. The work scope for the task was limited to an investigation of the stress levels in the subject subassemblies when subjected to seismic loads. Structural acceptance criteria used for the elastic calculations performed were as found in the overall rack design report as issued by the rack`s designer, Holtec International. Structural acceptance criteria used for the plastic calculations performed as part of this effort were as defined in Subsection NF and Appendix F of the ASME Boiler & Pressure Vessel Code. The results of the analyses will also apply to the 30 port fuel storage rack design that is also scheduled for installation in Pool 1 of ICPP 666. The results obtained from the analyses performed for this task indicate that the welds joining the inner tie block and corner tie block to the surrounding rack structure meet the acceptance criteria. Further, the structural members (plates and blocks) were also found to be within the allowable stress limits established by the acceptance criteria. The separate analysis performed on the inner tie plate confirmed the structural adequacy for both the inner tie plate, corner tie plate, and tie block bolts. The analysis results verified that the inner tie and corner tie block should be capable of transferring the expected seismic load without structural failure.

  7. Sulphur output from oil sands : dramatically changing Alberta's sulphur balance

    International Nuclear Information System (INIS)

    D'Aquin, G.

    2008-01-01

    This paper discussed sulphur production from Alberta's gas and oil sands industries. While sulfur derived from natural gas production in the province is expected to decline as natural gas reserves diminish, Alberta's oil sands contain high amounts of sulphur. It is not yet known how much sulphur will be produced from the province's oil sands facilities. Alberta had considerable stockpiles of sulphur in the 1970s. By 1980, inventories began to decline. By 1996, output had increased to 7.1 million tonnes. Alberta's sulphur inventory reached 9.7 million tonnes following the collapse of the Soviet Union's government mandated fertilizer industry. In 2006, sulphur supplies in Alberta reached 12 million tonnes. Reduced global output has now lowered sulphur stockpiles. Increases in sulphur prices tend to reduce market demand, and lower prices will not typically change the volume of sulphur produced as a byproduct of oil and gas operations. Bitumen-derived sulphur output is expected to exceed gas-derived sulphur output in the near future. Sulphur from oil sands processing is expected to increase by 5 million tonnes by 2017. Increased sulphur production levels in Alberta will present a significant challenge for all sectors of the hydrocarbon industry. It was concluded that developing a plan for storing, selling or disposing of the sulphur will help to ensure the profitability of oil sands operations

    Developing long-term carbon control strategies is important in energy intensive industries such as the oil sands operations in Alberta. We examine the use of cogeneration to satisfy the energy demands of oil sands operations in Alberta in the context of carbon management. This paper evaluates the role of cogeneration in meeting Provincial carbon management goals and discusses the arbitrary characteristics of facility- and product-based carbon emissions control regulations. We model an oil sands operation that operates with and without incorporated cogeneration. We compare CO 2 emissions and associated costs under different carbon emissions control regulations, including the present carbon emissions control regulation of Alberta. The results suggest that incorporating cogeneration into the growing oil sands industry could contribute in the near-term to reducing CO 2 emissions in Alberta. This analysis also shows that the different accounting methods and calculations of electricity offsets could lead to very different levels of incentives for cogeneration. Regulations that attempt to manage emissions on a product and facility basis may become arbitrary and complex as regulators attempt to approximate the effect of an economy-wide carbon price. - Highlights: ► We assess the effectiveness of cogeneration for carbon management in Alberta. ► Cogeneration can offset a significant portion of Alberta's high carbon electricity. ► CO 2 reduction potential of cogeneration may be higher if installed immediately. ► Product based policies should approximate the effect of an economy-wide policy.

  13. Is the restructuring of Alberta's power market on the right track? Evaluating Alberta's first two years of deregulation

    International Nuclear Information System (INIS)

    Wellenius, K.; Adamson, S.

    2003-07-01

    The performance of Alberta's restructured electricity market was evaluated since its move to wholesale competition in January 2001. This paper presents the following eight conclusions that the authors arrived at following the evaluation: (1) To meet growing demand, the electricity prices in Alberta would have increased regardless of the type of environment (regulated or not). Capacity investment was required, and it was believed that moving to competition was the best way to attract investors. (2) Success in attracting private investment was attained as a result of Alberta's open market. It has restored reliability of supply and moderated prices. (3) Price comparisons must take into account what the prices would have been if the market had remained regulated. Due to unique generation costs and regulatory environments, comparisons with other regulated jurisdictions is inappropriate. (4) Convergence with other energy rates that would have been seen under regulation is being noted with respect to Alberta's market prices. (5) Under deregulation, prices increase according to the need for new investment and fall after the investment is made. Alberta has been on a path toward continued reduction in wholesale prices since 2001. (6) The non-price benefits of restructuring include improved generation efficiency, captured residual value from regulated assets, and shifting investment risk of new capacity additions from consumers to generators.

    The Test of Emotional Intelligence (TIE) is a new ability scale based on a theoretical model that defines emotional intelligence as a set of skills responsible for the processing of emotion-relevant information. Participants are provided with descriptions of emotional problems, and asked to indicate which emotion is most probable in a given situation, or to suggest the most appropriate action. Scoring is based on the judgments of experts: professional psychotherapists, trainers, and HR specialists. The validation study showed that the TIE is a reliable and valid test, suitable for both scientific research and individual assessment. Its internal consistency measures were as high as .88. In line with theoretical model of emotional intelligence, the results of the TIE shared about 10% of common variance with a general intelligence test, and were independent of major personality dimensions.

    Full Text Available Some social connections are stronger than others. People have not only friends, but also best friends. Social scientists have long recognized this characteristic of social connections and researchers frequently use the term tie strength to refer to this concept. We used online interaction data (specifically, Facebook interactions to successfully identify real-world strong ties. Ground truth was established by asking users themselves to name their closest friends in real life. We found the frequency of online interaction was diagnostic of strong ties, and interaction frequency was much more useful diagnostically than were attributes of the user or the user's friends. More private communications (messages were not necessarily more informative than public communications (comments, wall posts, and other interactions.

  20. Annual compensation for pipelines in Alberta

    International Nuclear Information System (INIS)

    2008-11-01

    The Surface Rights Board (SRB) in Alberta held a hearing in November 2007 to address three issues involving a pipeline for Enbridge Pipelines (Athabasca) Inc. as well as several land owner issues in Townships 66-68 and Ranges 17-19, all west of the 4th Meridian. The issues the SRB examined were the appropriate amount (i.e. magnitude) of compensation payable under right of entry orders under consideration; the appropriate structure of the compensation award; and to whom the compensation was payable. This document presented a review by the Farmer's Advocate Office (FAO) of the published decision of the SRB. The verbatim decision and rationale used by the SRB to award annual compensation for loss and/or ongoing nuisance and inconvenience was presented. The document could be useful to landowners as they determine their negotiation strategy when faced with considering future pipeline access agreements. The document included a discussion of the context for the decision and a case review. Specific topics that were covered included the rationale for the decision; long term effects of pipeline arguments and SRB commentary; the award and determination; and what still needs to be done. It was concluded that the SRB requires evidence in order to answer several questions regarding the magnitude of any losses, and to what degree, if any, had the nuisance, inconvenience, and loss of rights already been anticipated and factored into the operator's final offer

  1. A retailer's perspective on generation in Alberta

    International Nuclear Information System (INIS)

    Willerton, K.

    2003-01-01

    There are several reasons for a retailer to invest in power generation. This investment acts as a risk management hedge against fixed price retail load, while improving competitiveness in illiquid wholesale markets. Investing in power generation leverages the retailer's wholesale trading capabilities. It also provides appropriate returns. Some of the factors that ensure the success of a retailer investing in power generation are low cost structure, low risk, strong forward commodity market, owners with large healthy balance sheets, and willingness to finance projects entirely with equity. A cost comparison was presented for different generation technologies. ENMAX chose to invest in wind power since the costs were comparable to that of other technologies. In addition, green credits will lower the cost of wind power. With low environmental impacts and no fuel risk, wind energy fitted ENMAX's retail strategy. Green power at ENMAX (GREENMAX) was the first to implement a Green Power Residential program in 1998, followed by the Green Power Commercial program in 2000. The author discussed the McBride Lake Wind Farm located near Fort MacLeod, Alberta. figs

  2. Alberta books big revenues in 1996

    International Nuclear Information System (INIS)

    Curran, R.

    1996-01-01

    A 17.9 per cent increase over 1995 in oil and gas revenues were reported for Alberta through August 1996. Revenues from crude oil were up 12.6 per cent and from natural gas 30.7 per cent. The level of increase in revenues is expected to hold for the remainder of the year, save for the prospects of Iraq re-entering the market in force. This would cause a steep decline in prices and some panic trading in energy stocks. Nevertheless, producers are well positioned for the year ahead, as capital spending and drilling activity are based on lower price forecasts. Oil production over 1995 was down slightly through August. Light and medium crude production was down 4.5 per cent. Synthetic production fell by 0.8 per cent. Natural gas production will have a record year. Through August output was up 4.6 per cent over 1995, sales were up 19.3 per cent, and exports were ahead by just under one per cent. Natural gas liquids were the biggest revenue booster, increasing by 46.3 per cent over 1995

    The Reclamation Research Technical Advisory Committee (RRTAC) was appointed by the Alberta Land Conservation and Reclamation Council to assist in technical matters related to the development and administration of the Council's research program. RRTAC develops reclamation research under four major program areas, and activities in these areas during the year are described in this report. The Plains Coal Reclamation Research Program addresses questions relating to groundwater and soil reconstruction in plains coal mining zones. The Mountain and Foothills Reclamation Research Program focuses on water management, soil reconstruction, reforestation, and wildlife habitat development, with objectives including control of erosion on a variety of disturbances such as coal mines and ash pits. The Oil Sands Reclamation Research Program is attempting to develop techniques to establish self-sustaining, erosion-free cover on oil sand tailings pond dikes, and to return tailings sand storage and overburden dumps to productive forests. The Oil and Gas Reclamation Research Program is concerned with disposal of drilling wastes and reclamation of lands disturbed by oil and gas activities. Under each program, the objectives, basic problems investigated, and research approach are presented, followed by description of specific projects involving such subjects as hydrology, revegetation, soil-water interactions, landscape and watershed design, soil reconstruction and amendment, and soil compaction.

  5. The potential for coalbed methane (CBM) development in Alberta

    International Nuclear Information System (INIS)

    2001-09-01

    This report presents fiscal and regulatory recommendations of the coalbed methane (CBM) Advisory Committee which consists of representatives from Alberta's oil and gas industry who participated in a study to determine the potential for coalbed methane development in the province. CBM is a natural gas produced as a by-product of the coal formation process. This study examined the CBM reserve base in Alberta along with the necessary steps and strategies required to develop it. There is increased interest in natural gas from Alberta's coal resources because of the forecast for reasonable natural gas prices coupled with an increase in energy demand. The remaining established natural gas reserves are estimated at 43 trillion cubic feet and unconventional supplies of natural gas will be needed by 2008 to meet this increasing demand. The recoverable reserves of CBM are estimated to be between 0 and 135 trillion cubic feet. This report discussed the following mitigation strategies suggested by industry that may applicable to CBM development in Alberta: (1) potential technical mitigation strategies, (2) potential land access and tenure strategies, (3) potential water disposal and diversion mitigation strategies, (4) potential non-technical mitigation strategies, and (5) potential economic mitigation strategies. The study concluded that since no two CBM basins are the same, it is necessary to have good baseline resource inventory data. It was also noted that evolving management, drilling and completion techniques will continue to enhance the economic understanding of Alberta's extensive coal beds. It was suggested that lessons from CBM development in the United States can be useful for development in Alberta since there are currently no publicly recognized commercial production of CBM in Alberta. 24 refs., 6 tabs., 25 figs

    This strategic plan is the key initiative established under 'Alberta's Framework for International Strategies'. Its objective is to ensure the wellbeing of Albertans, sustaining Alberta's environment, and economic growth through successfully taking advantage of Alberta's many opportunities for marketing its goods, products, and services. It is predicated on industry and government continuing to work together to sustain a strong market-driven economy, strengthen Alberta's economic advantages and build an economic environment conducive to investment and growth in quality jobs. At present more than 150 foreign markets buy Alberta's goods and services, but the obvious focus of any strategy must be those regions and sectors of industry that offer the greatest possibilities for new and expanded opportunities for Alberta business. Accordingly, this strategy identifies priorities, selects the best initiatives and develops activities to achieve economic growth. Adding value to Albertan commodities before they are being shipped to export markets is a particular objective of the plan. An equally important consideration is to achieve growth through expansion of existing investments, attract new investment to the province, and to increase exports in response to international market and investment opportunities for Alberta's goods and services. Major topics discussed in the document include a discussion of the importance of trade and investment, a thorough analysis of the marketing priorities, the strategic framework, and priority market profiles for the United States, Japan,China, other Asia-Pacific markets, the European Union, Mexico, the Middle East and South Asia, and South America.

  7. Climatic change and environmental implications in the Medicine Hat region using Billings, Montana as an analogue

    International Nuclear Information System (INIS)

    Proudfoot, W.A.

    1994-01-01

    There is concern that climatic change due to anthropogenic enhancement of the greenhouse effect may have considerable impacts on the natural and agricultural environments in Canada. The Palliser Triangle in the southern prairie region is an area in which the impacts of climatic change could be significant; it is an important agricultural zone and is already sensitive due to its semi-arid climate. The possible effects of a change in the climate of the Medicine Hat (Alberta) area in the Palliser Triangle is examined through the use of a regional analogue in a warmer, more southerly area. The selected analogue region is the area around Billings, Montana. Aspects of the natural environment, including potential vegetation distribution, frost-free period, and drought, as well as aspects of the agricultural environment, including agricultural practices and examination of wheat yields, are studied within each region. Comparisons are drawn between the two regions to evaluate whether significant differences exist in the environmental aspects examined. It is shown that although a change in Medicine Hat's climate to one more like that of Billings may not have drastic impacts on the environment, such a change may require adjustments in current practices or adaptations to altered environmental conditions. Reviews of several policy areas will be necessary to ensure appropriate adjustments in agricultural or resource management practices. Regional analogy is shown to be an essential preliminary tool for determining possible effects of climatic change. 138 refs., 42 figs., 22 tabs

    The current status of the Montana Alberta Tie Ltd. (MATL) merchant transmission project was outlined with reference to the business concept, the advantages of the project and market opportunities. Some of the challenges facing the project were discussed along with lessons learned and accomplishments thus far. MATL is preparing to construct a privately funded transmission line between Lethbridge, Alberta and Great Falls, Montana. The project represents the first direct power transmission inter-connection between Montana and Alberta. The 346 km, 230 kV AC transmission line with phase shifting transformer and 300 MW transfer capacity will be a synchronous interconnection and will improve the reliability of the entire electric systems in both Montana and Alberta. The benefits of the interconnected power system include increased reliability and stability of the existing power grids; better import/export capabilities; more competition and options in the marketplace; greater flexibility in scheduling generator maintenance; and, optimal allocation of generation resources. tabs., figs

    Halla, S.

    1999-01-01

    There has been an ongoing discussion concerning the harmonization of waste management requirements within Alberta between the Alberta Energy and Utilities Board (EUB) and Alberta Environment (AENV), with the ultimate goal of publishing a memorandum of understanding (MOU) that will lay out the division of responsibilities between the two authorities on this matter. An overview is included of waste management in Alberta and of the harmonization agreements attained to date, with a stress on oil field waste issues. The EUB and AENV developed a MOE on the harmonization of waste management in Alberta, and a discussion is made of the concept of equivalency, which is used in the development of 'EUB guide 58: oilfield waste management requirements for the upstream petroleum industry' and will be a guiding principle for the MOU. Although the EUB's processes for waste management will not be exactly the same as AENV's, the EUB has made the commitment that, as a minimum, the requirements will provide the same level of environmental protection and public safety equivalent to that provided by AENV

    This paper describes the potential economic impact and benefits to Alberta from the proposed development of the Alaska Highway Pipeline (AHP) and the Mackenzie Valley Pipeline (MVP). It also includes a planning framework for business and industry in the province. Each proposed pipeline was evaluated separately. The paper includes a list of Alberta companies that stand to benefit from the construction of one or both pipelines. The main findings indicate that northern pipeline development will bring opportunities to Alberta business in design, construction and management. There will be a secondary impact on petrochemical industries and infrastructure. Both pipeline developments will increase employment and yield billions of dollars in gross domestic product. The existing oil and gas industry in Alberta will receive value-added opportunities in areas of specialized expertise such as natural gas and natural gas liquid storage, natural gas liquid processing, and gas to liquid technology projects. The industry will also benefit from power generation and cogeneration. The northern pipelines have the potential to improve the role of First Nations in economic development. Gas consumers in Alberta should benefit from a secure supply of gas and lower prices. refs., tabs., figs

    As of January 1, 2001, deregulation of the electricity market in Alberta became a reality, and was accompanied by steady growth in demand for electricity combined with other factors that pushed the price of electricity upward. The Power Pool of Alberta ensures that market operations are open and fair. Its mandate, under the Electric Utilities Act, is the overall market surveillance in Alberta's electric industry. It is accomplished by working closely with industry and seeking feedback through four standing committees: Human Resources, Operations, Finance and Audit, and Balancing Pool. The goal for the coming years is to build confidence in the market, whereby consumers are confident about the fairness of the market price for electricity in Alberta, the choices available, and the continued reliability of the electric system in Alberta. The Energy Trading System was explained with information about system control and customer service, and details provided on the consultation and collaboration processes.

  16. Make the Alberta Carbon Levy Revenue Neutral

    Directory of Open Access Journals (Sweden)

    Kenneth J. McKenzie

    2016-04-01

    Full Text Available The new carbon levy of $30 per tonne, announced in November 2015 as part of the report issued by the Alberta government’s Climate Leadership Panel, is a positive move in the direction of pricing carbon emissions. The levy is expected to generate $3 billion in net revenue by 2018, and possibly as much as $5 billion by 2030. While there is some discussion in the report of what should be done with the revenues generated by the carbon levy, it is somewhat vague on the details, leaving a number of options open to the government. The purpose of this briefing paper is to argue that the revenues from the carbon levy should be used to lower existing taxes – the carbon tax should be revenue neutral, generating no new net revenue for the government. The basic argument is that the carbon levy can be viewed through two lenses. The first lens is the imposition of a price on carbon emissions which (at least partly reflects the social costs of emissions. Viewed through this price lens, the carbon levy plays an important role in incenting firms and individuals to change their behaviour and move towards less carbon intensive activities. The second lens is the role of a carbon tax as a part of the broad revenue system. Viewed through this tax lens, a carbon tax is not a very good, or efficient, way of generating revenue. The reason for this is somewhat nuanced, but the basic idea is that the carbon tax is applied to a narrower base than broader-based taxes. Broad based taxes generally impose lower costs on the economy than narrow based taxes. Moreover, carbon taxes interact with other taxes in the economy, exacerbating the economic costs associated with those taxes. And those costs are quite high – research shows that the total cost to the economy of raising an additional $1 in revenue through the corporate income tax in Alberta is $3.79; for the personal income tax the cost is $1.71. These taxes therefore impose higher costs on the economy than they raise

    The Alberta renewable diesel demonstration (ARDD) was a demonstration project aimed at providing information and operating experience to stakeholders in the diesel fuel industry. The demonstration took renewable diesel from the lab to the road, providing hands-on experience at 2 and 5 per cent blends (B2 in winter and B5 in shoulder and summer seasons). The ARDD fleet consisted of 59 vehicles running on two types of renewable diesel, notably fatty acid methyl ester (FAME) and hydrogenated-derived renewable diesel (HDRD). This report was a summary of the observations of the ARDD. The report provided a general account of the project scope, methods and observations employed in a multi-stakeholder, real-world demonstration of low-level renewable diesel fuels in challenging winter conditions. The purpose of the report was to provide feedback to stakeholders regarding the use of renewable diesel fuels in Canada's on-road diesel fuel market and to confirm the operability of low level renewable diesel blends under the specific conditions tested ensuring full and continuous compliance with CAN/CGSB 3.520. The report discussed Canada's fuel distribution system in western Canada; the blending facility; blending techniques; fuel retail locations; fuel properties; fuel handling; fuel selection; and fuel testing. It was concluded that the ARDD demonstrated that B2 blends of canola methyl ester and 2 per cent blends of hydrogenation derived renewable diesel were fully operable in winter conditions in the study area when cloud points were adjusted to meet CAN/CGSB requirements. 4 refs., 15 tabs., 20 figs., 2 appendices.

    The University of Montana's Department of Physics and Astronomy runs the state of Montana's only professional astronomical observatory. The Observatory, located on nearby Blue Mountain, houses a 16 inch Boller and Chivens Cassegrain reflector (purchased in 1970), in an Ash dome. The Observatory sits just below the summit ridge, at an elevation of approximately 6300 feet. Our instrumentation includes an Op-Tec SSP-5A photoelectric photometer and an SBIG ST-9E CCD camera. We have the only undergraduate astronomy major in the state (technically a physics major with an astronomy option), so our Observatory is an important component of our students' education. Students have recently carried out observing projects on the photometry of variable stars and color photometry of open clusters and OB associations. In my poster I will show some of the data collected by students in their observing projects. The Observatory is also used for public open houses during the summer months, and these have become very popular: at times we have had 300 visitors in a single night.

  20. Should upgrading and refining be enhanced in Alberta?

    International Nuclear Information System (INIS)

    Asgarpour, S.

    2006-01-01

    Although world oil prices are rising, the price of bitumen remains stable. It was noted that surplus refinery capacity is disappearing and that skilled labour, infrastructure, transportation systems, environmental management and technology development are among some of the challenges facing heavy hydrocarbon development. Pie charts indicating global reserves of crude oil and heavy crude oil showed that although the Middle East leads in world proven oil reserves, nearly half of the heavy crude oil and natural bitumen deposits are in Canada. As a global energy leader, Alberta is using its' world class expertise to develop the vast energy resources of the province and to market these resources and abilities to the world. This presentation summarized processing activities in Alberta and outlined the markets for petrochemicals. A graph representing North American petroleum supply and demand from 2001 to 2019 was also presented along with a review of Alberta's upgrading and refining capacity and infrastructure opportunities for crude oil, natural gas, petrochemicals and electricity. Alberta's crude oil markets by 2020 are likely to be the Far East, California, Heredity's, Wyoming, Chicago, Cushing, United States Gulf Coast, and the East Coast. The benefits of upgrading in Alberta include inexpensive feedstock, existing upgrader and petrochemical sites and low transportation costs. In addition, more refining capacity in the province would provide market diversification for bitumen products; higher investment and value-added in Alberta; opportunity to provide feedstock to petrochemicals; production of synthetic diluent in the province; and, smaller environmental footprint and greater energy efficiency. The cumulative impact of oil sands development on government revenues was discussed along with the challenge of addressing the issue of a skilled labour shortage, infrastructure needs, and developing a business case for a carbon dioxide pipeline. tabs., figs

    2017-01-01

    Background: The International Agency for Research on Cancer has classified outdoor air pollution (fine particulate matter [PM2.5]) as a Group 1 lung carcinogen in humans. We aimed to estimate the proportion of lung cancer cases attributable to PM2.5 exposure in Alberta in 2012. Methods: Annual average concentrations of PM2.5 in 2011 for 22 communities across Alberta were extracted from the Clean Air Strategic Alliance Data Warehouse and were population-weighted across the province. Using 7.5 µg/m3 and 3.18 µg/m3 as the annual average theoretical minimum risk concentrations of PM2.5, we estimated the proportion of the population above this cut-off to determine the population attributable risk of lung cancer due to PM2.5 exposure. Results: The mean population-weighted concentration of PM2.5 for Alberta in 2011 was 10.03 µg/m3. We estimated relative risks of 1.02 and 1.06 for theoretical minimum risk PM2.5 concentration thresholds of 7.5 µg/m3 and 3.18 µg/m3, respectively. About 1.87%-5.69% of incident lung cancer cases in Alberta were estimated to be attributable to PM2.5 exposure. Interpretation: Our estimate of attributable burden is low compared to that reported in studies in other areas of the world owing to the relatively low levels of PM2.5 recorded in Alberta. Reducing PM2.5 emissions in Alberta should continue to be a priority to help decrease the burden of lung cancer in the population. PMID:28659352

    This study determined some biological compounds (fatty acid compositions, lipid-soluble vitamins, sterols, flavonoids), radical scavenging capacities and antimicrobial activities in the seeds of Nepeta italica L. and Sideritis montana L. subsp. montana. It was found that palmitic acid (C16:0; 8.54+-0.13-3.05+-0.04%), oleic acid (C18:1 n9, 22.41+-0.8-18.83+-0.1%) and a-inolenic acid were the dominant fatty acids in both Nepeta italica L. and Sideritis montana L. subsp. montana. It was concluded that both Nepeta italica L. and Sideritis montana L. subsp. montana contained stigmasterol and ergosterol as well as beta-sitosterol. The present findings show that Nepeta italica L. contains morin, catechin, naringin and Sideritis montana L. subsp. montana contains morin, naringenin as major flavonoids. It was also determined that methanol extracts of Nepeta italica L. and Sideritis montana L. subsp. montana were most effective against DPPH radicals. The results of the present study show that the vitamins, flavonoids and fatty acid extracts in the seeds of N. italica L. and S. montana L. subsp. montana prevented the growth of the microorganisms used in the tests at different ratios.

  15. Grid-Tied Photovoltaic Power System

    Science.gov (United States)

    Eichenberg, Dennis J.

    2011-01-01

    A grid-tied photovoltaic (PV) power system is connected directly to the utility distribution grid. Facility power can be obtained from the utility system as normal. The PV system is synchronized with the utility system to provide power for the facility, and excess power is provided to the utility. Operating costs of a PV power system are low compared to conventional power technologies. This method can displace the highest-cost electricity during times of peak demand in most climatic regions, and thus reduce grid loading. Net metering is often used, in which independent power producers such as PV power systems are connected to the utility grid via the customers main service panels and meters. When the PV power system is generating more power than required at that location, the excess power is provided to the utility grid. The customer pays the net of the power purchased when the on-site power demand is greater than the onsite power production, and the excess power is returned to the utility grid. Power generated by the PV system reduces utility demand, and the surplus power aids the community. Modern PV panels are readily available, reliable, efficient, and economical, with a life expectancy of at least 25 years. Modern electronics have been the enabling technology behind grid-tied power systems, making them safe, reliable, efficient, and economical with a life expectancy equal to the modern PV panels. The grid-tied PV power system was successfully designed and developed, and this served to validate the basic principles developed, and the theoretical work that was performed. Grid-tied PV power systems are reliable, maintenance- free, long-life power systems, and are of significant value to NASA and the community. Of particular value are the analytical tools and capabilities that have been successfully developed. Performance predictions can be made confidently for grid-tied PV systems of various scales. The work was done under the NASA Hybrid Power Management (HPM

    2009-02-15

    A high number of cases of cholangiocarcinoma, a rare form of bile duct cancer, as well as high rates of other cancers were reported by a physician working in Fort Chipewyan, Alberta in 2006. Concerns were raised by local residents, attributing cancers in their community to environmental contamination from a range of industrial development including the oil sands development, uranium mining and pulp mills. However, an initial review of the Alberta Cancer Registry did not confirm an increased incidence of cancer in Fort Chipewyan. In the summer/fall of 2007, a working group was formed to support the Alberta Cancer Board in doing a cluster investigation based on the guidelines of the United States Centre for Disease Control and Prevention. This report presented an investigation to determine if there was an elevated rate of cholangiocarcinoma in Fort Chipewyan and whether there was an elevated rate of cancers overall in Fort Chipewyan. The report provided background information on the Athabasca oil sands, uranium mining, and Fort Chipewyan as well as previous investigations of cancer incidence in Fort Chipewyan. Study methods were also presented with particular reference to study and comparison populations; cancer classification and inclusion criteria; active case ascertainment and verification; methods of analysis; and ethical approval. Results were also presented. The specific cancers that were discussed were cholangiocarcinoma, leukemia, colon cancer, and cancer in First Nations in Alberta. It was concluded that the observed number of cases of cholangiocarcinoma was within the expected range. 121 refs., 12 tabs., 3 figs., 5 appendices.

    2006-04-01

    This economic profile and forecast report for the province of Alberta revealed that nearly every sector of the economy is operating at full, or near full capacity. Alberta's strong economy is a result of high energy prices, rapid population growth and rising employment. Increased provincial government spending along with tax reductions for businesses also contribute to a strong economy. However, the the province still faces some economic challenges, including a general labour shortage. Forestry and agriculture are under pressure of low commodity prices and high input costs, and the province has not articulated a long-term strategy for managing non-renewable natural resource revenue. In addition, the provincial economy is highly dependent upon volatile energy prices. Despite these challenges, the report states that the momentum is on the side of continued economic growth in Alberta. The Canada West Foundation is forecasting real growth in the gross domestic product of 5.2 per cent for 2006 and 4.7 per cent for 2007. The strong energy sector is largely responsible for much of Alberta's economic growth. An estimated 20,000 wells will be drilled in the province in 2006, and high oil prices will lead to record drilling and oil sands investment. This report also highlighted the economic activity in other sectors, including manufacturing, tourism, international exports, hi-tech, forestry, agriculture, and construction. Information regarding interprovincial migration and population growth was included along with public finances. 16 figs

  20. Alberta's air quality index : facts at your fingertip

    International Nuclear Information System (INIS)

    2003-06-01

    Alberta Environment measures the airborne concentrations of carbon dioxide, fine particulate matter, nitrogen dioxide, ozone and sulphur dioxide on a continuous basis at air quality monitoring stations in Edmonton, Calgary, Red Deer and Beaverlodge. Every hour, the readings are converted to an Air Quality Index (AQI) number to report on Alberta's outdoor air quality as either good, fair, poor or very poor. The categories relate to guidelines under Alberta's Environmental Protection and Enhancement Act and reflect the maximum acceptable levels specified by the National Ambient Air Quality Objectives. Current air quality conditions are available to the public through Alberta Environment's web site or by phoning a toll free number. Both Edmonton and Calgary report good air quality at least 90 per cent of the time. Occasionally, air quality in the two cities may reach the fair category, but it is seldom poor. Fair, poor or very poor air quality occurs with strong temperature inversion and light winds. Under these conditions, air pollutants, usually from automobiles, are trapped in a layer of stagnant air. Fair and poor air quality can also be caused by summer heat when photochemical smog forms by chemical reactions with oxides of nitrogen and volatile hydrocarbons. 1 ref., 1 tab., 1 fig

    This new publication informs readers about what the Alberta Energy and Utilities Board (EUB) did in the past year, including important regulatory issues, trends and initiatives. The EUB is an agency of the provincial government, established to regulate Alberta`s energy resource and utility sectors. It is part of the Alberta Ministry of Energy. The four main functions of the Board are regulatory initiatives, license applications, enforcement and information. This publication summarized the EUB`s position regarding flaring (both solution gas flaring and well test flaring), and Board activities in the areas of animal health concerns, the gas over bitumen controversy, the deregulation of the electric industry and what it means to the EUB, improvements in data quality as a result of improved industry compliance in reporting, and a variety of issues related to the oil sands and the negotiated settlement process. Also, the Board has been proactive in the area of oilfield waste management guidelines, proliferation policies for gas processing facilities, sulphur recovery guidelines, and the expansion of the orphan well program to include facilities and pipelines. As a measure of the success of the EUB, a recent survey of 19 randomly selected focus groups praised EUB for its impartiality, fair and equitable enforcement and independence. It was also praised for its technically competent and experienced staff, its access to quality information and the clarity of its mandate, regulatory requirements and processes. The Board`s efforts in the area of timely stakeholder consultation was highlighted. tabs., figs.

  17. Protecting consumer interests in Alberta's deregulated electricity market

    International Nuclear Information System (INIS)

    Bradford, J.A.

    2003-01-01

    This paper explains why the province of Alberta decided to deregulate its electricity sector. In the early 1990s, electricity rates were reasonable in Alberta, there was no utility debt, and electricity costs were low. In 1994 California's open access transmission system suggested that open markets would result in lower electricity rates and attract new economic activity. The government of Alberta also believed that competitive markets would set prices with no need for economic regulation. In the initial transition to competition, regulated electricity rates were offered to customers who were not ready to switch to the new competitive market. The RRO rate was set by the Alberta Energy and Utilities Board (EUB). The rates included the forecasted cost of purchasing energy from markets, cost of system access, and retail service costs. The end of the RRO rate was scheduled for 2005 when the market was expected be well developed. This paper also describes other protection mechanisms for consumers. Alberta's new electricity policy (NEP) eliminates generator participant costs related to transmission. EUB's zonal interconnection charges are also overruled along with the EUB-approved 50/50 division of transmission costs. Under the NEP, the ISO is to build transmission in anticipation of new generation. Consumers will fund the total cost to build new transmission capacity for exports and imports. This new transmission policy is a complete change from the original government policy which allocated some transmission costs to generators. The sudden change in policy was due to pressure from oil sands producers and oil sands co-generation developers. The claimed benefit to Albertans is a 25 per cent reduction in pool price and greater system reliability. However, the author cautioned that government interference with competitive electricity markets will cripple the electric power industry in the foreseeable future because it interferes with market prices

  18. Alberta immigrant integration into the petroleum industry : final research report

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2008-02-15

    Alberta is in the midst of a labour shortage, especially in the petroleum industry. Traditionally, the petroleum industry has secured employees by hiring them away from competitors, service providers, other geographic locations, or other industries, mostly by escalating worker compensation. However, this is no longer seen to be a sustainable solution due to higher industry costs and inflation. A good opportunity exists for Alberta's oil and gas industry to address worker demand and minimize the negative impacts associated with current and future labour concerns by increasing the participation of workers who are under-represented in the workforce, such as Aboriginals, women, and internationally trained workers. This report presented the details of a project called the Alberta immigrant integration into the petroleum industry project in order to determine the tools, resources and support processes needed by petroleum industry employers to increase the employment and retention of internationally trained workers already living in Alberta into the upstream petroleum industry. The report outlined the gaps in information, tools, resources and services that were preventing the petroleum industry from taking advantage of the skills and experience offered by Alberta's labour pool of internationally trained workers in any significant way. The report also presented an overview of strategic priorities and recommended activities, duly endorsed by stakeholders, in order to improve the recruitment and integration of internationally trained workers into the petroleum industry workforce. It was concluded that employers who develop the skills and capability to effectively recruit and integrate internationally trained workers into their workforce will have a clear advantage in the competition for skilled employees. 3 refs., 2 figs.

    Several countries around the world have been using rubber crumb (RC) for pavement applications for more than 20 years. The performance of asphalt pavements is enhanced by the use of recycled tires, which has the added advantage of solving the problem of tire disposal. In 2002, the Tire Recycling Management Association of Alberta (TRMA) and Alberta Transportation (AT) evaluated the feasibility and performance of an overlay using asphalt rubber (AR) pavement in Alberta. A partnership in the project was formed by AT, the City of Calgary, the City of Edmonton, and Strathcona County, where each one paved one section of a road with AR in conjunction with a section using conventional or other asphalt mixture types. The roads selected were: (1) 112 Avenue North West in Calgary, (2) 17 Street and Baseline Road in Strathcona County, (3) 137 Avenue in Edmonton, and (4) highway 630 in the vicinity of North Cooking Lake (Alberta Transportation). Two different AR pavement thicknesses were used to study the effects of overlay thicknesses on the performance of the overlay. The structural and functional factors were monitored before, during and after the construction of all sections. The preliminary evaluation of the application of AR in Alberta was presented, along with a summary of test results and performances of AR pavement sections. A full freeze-thaw cycle is required (Spring 2003) before the results of the analysis of the testing are known. The reduced thickness AR sections performed in a similar manner to those with full thickness AC sections. 10 refs., 5 tabs., 3 figs.

    1999-01-01

    The legislative and regulatory regime regarding gas flaring in Alberta was reviewed. The issue of gas flaring has received much attention from petroleum industry regulators in Alberta. Residents living in the vicinity of flares have identified them as sources of odour, smoke, noise and air quality-related health concerns. Sulfur dioxide and carbon dioxide emissions from the flare stacks may contribute to acid rain and the greenhouse effect. The Strosher Report, released by the Alberta Research Council in 1996, has also identified about 250 different compounds in flare emissions, including volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs) and other products of incomplete combustion. The public opposition to solution gas flaring has caused regulators to consider new options designed to reduce the adverse economic and environmental impacts that may be associated with gas flaring. This paper discusses the roles of the Alberta Energy and Utilities Board (EUB) and Alberta Environmental Protection in administering legislation that impacts on gas flaring. In March 1999, the EUB released a guide containing the following five major points regarding gas flaring: (1) implementation of the Clean Air Strategic Alliance's (CASA's) recommendations to eventually eliminate flaring, by starting immediately to reduce flaring, and improve the efficiency of flares, (2) adoption of the CASA schedule of reduction targets for solution gas flaring, (3) conducting a review of the current approval process for small-scale electrical generation systems to encourage co-generation as a productive use of solution gas that is being flared, (4) creating better public notification requirements for new and existing facilities, and (5) discussing conflict resolution between operators and landowners. 26 refs

  1. Economic impacts of Alberta's oil sands, volume 1

    In 2004, the international media recognized Alberta's oil sands as part of the global oil reserves, thereby establishing Canada as second to Saudi Arabia as potential oil producing nations. The economic impacts of Alberta's oil sands industry on economies were assessed at regional, provincial and international levels for the 2000 to 2020 period. A customized input-output model was used to assess economic impacts, which were measured in terms of changes in gross domestic product; employment and labour income; and, government revenues. Cumulative impacts on employment by sector and by jurisdiction were also presented. An investment of $100 billion is expected through 2020, resulting in production of crude bitumen and synthetic crude oil outputs valued at about $531 billion. The impact of the oil sands industry on local employment was also evaluated. It was shown that activities in the oil sands industry will lead to significant economic impact in Alberta, Ontario, Quebec and the rest of Canada. Alberta's local economy would be the main beneficiary of oil sands activities with nearly 3.6 million person years employment created in Alberta during the 2000 to 2020. Another 3 million person years employment would be created in other Canadian provinces and outside Canada during the same time period. A sensitivity analysis on the responsiveness to oil prices and the removal of various constraints incorporated in the main analysis was also presented. The federal government will be the largest recipient of revenues generated to to oil sands activities. The results of the study were compared with that of the National Task Force on Oil Sands Strategies. This first volume revealed the results of the study while the second volume includes the data and detailed results. 48 refs., 57 tabs., 28 figs

    Barbed suture technology is becoming increasingly popular in plastic surgery and is now being used in body contouring surgery and facial rejuvenation. We describe the novel application of a barbed suture as a running tie-over dressing for skin grafts. The barbs act as anchors in the skin, so constant tensioning of the suture is not required. The bidirectional nature of the suture prevents any slippage, and the barbs even act as a grip on the underlying wool dressing. Furthermore, the method described is both quick and simple to learn and would be useful for the sole operator.

    2012-01-01

    The Montana Valley and Foothill Prairies Ecoregion comprises numerous intermountain valleys and low-elevation foothill prairies spread across the western half of Montana, on both sides of the Continental Divide (Omernik, 1987; U.S. Environmental Protection Agency, 1997). The ecoregion, which covers approximately 64,658 km2 (24,965 mi2), includes the Flathead Valley and the valleys surrounding Helena, Missoula, Bozeman, Billings, Anaconda, Dillon, and Lewistown (fig. 1). These valleys are generally characterized by shortgrass prairie vegetation and are flanked by forested mountains (Woods and others, 1999); thus, the valleys’ biotas with regards to fish and insects are comparable. In many cases, the valleys are conduits for some of the largest rivers in the state, including Clark Fork and the Missouri, Jefferson, Madison, Flathead, Yellowstone, Gallatin, Smith, Big Hole, Bitterroot, and Blackfoot Rivers (fig. 2). The Montana Valley and Foothill Prairies Ecoregion also includes the “Rocky Mountain front,” an area of prairies along the eastern slope of the northern Rocky Mountains. Principal land uses within the ecoregion include farming, grazing, and mining. The valleys serve as major transportation and utility corridors and also contain the majority of Montana’s human population. The Montana Valley and Foothill Prairies Ecoregion extends into 17 mostly rural counties throughout western Montana. Only three of the counties—Carbon, Yellowstone, and Missoula—are part of a metropolitan statistical area with contiguous built-up areas tied to an employment center. Nearly two-thirds of Montana residents live in nonmetropolitan counties (Albrecht, 2008). Ten of the counties within the ecoregion had population growth rates greater than national averages (9–13 percent) between 1970 and 2000 (table 1). Ravalli and Gallatin Counties had the highest growth rates. Population growth was largely due to amenity-related inmigration and an economy dependent on tourism

  8. Developing a Climate Change Boundary Organization: the Montana Adaptation Exchange

    2016-12-01

    Small-population large-area states like Montana are often challenged by a need to offer timely and relevant climate-change information that addresses diverse and widely dispersed stakeholder groups. In Montana, filling the gap between science and various types of decision-makers has motivated development of the first Montana Climate Assessment (MCA1), to be released in 2017 with a focus on climate-change impacts for agricultural, water and forestry sectors. To sustain and build on the MCA1 effort, we are also in the process of creating a Boundary Organization (defined by the National Academy of Sciences) called the Montana Adaptation Exchange (the Exchange); this entity will facilitate the flow of information across the boundaries between science, knowledge and implementation. In Montana, the Exchange brings scientists and practitioners together to seek solutions related to climate-change adaptation and other pressing environmental and social-economic challenges. The Montana Adaptation Exchange (1) is a collaborative partnership of members from the science and practitioner communities under a shared governance and participatory model; (2) presents research that has been vetted by the scientific community at large and represents the current state of knowledge; (3) allows for revision and expansion of assessments like the MCA; (4) communicates relevant, often technical, research and findings to a wide variety of resource managers and other stakeholders; (5) develops and maintains an extensive online database that organizes, regularly updates, and makes research data products readily available; and (6) offers an online portal and expert network of affiliated researchers and climate adaptation specialists to provide effective customer support. Boundary organizations, such as the Montana Adaptation Exchange, offer a scalable path to effectively move from "science to knowledge to action" while also allowing stakeholder needs to help inform research agendas.

Total asthma-related disability days, including in-bed days and activity-restricted days, were estimated by multiplying the difference in the means of total disability days between asthmatics and nonasthmatics adjusted for sociodemographic characteristics and other health conditions by a multiple linear regression, with the number of asthmatics in the population. Number of productivity loss days was a sum between the number of in-bed days (absenteeism and the number of activity-restricted days multiplied by a reduction in functional level (presenteeism, adjusted for five working days per week. Other data from Alberta or Canadian published literature, such as a reduction in functional level of 20%–30%, a labor participation rate of 73%, and an average wage of $158 per day in 2005, were also used for analyses.Results: The prevalence of asthma was estimated at 8.5% among approximately 2.1 million people of working age in Alberta in 2005. The difference in the means of total disability days between asthmatics and nonasthmatics was 0.487 (95% CI: 0.286–0.688 in a period of two weeks or 12.7 (7.5–17.9 in one year. With the reduction in functional level of 20%–30%, the number of asthma-related productivity loss days was estimated from 442 (259–624 to 533 (313–753 thousand, respectively. The corresponding cost was from $70 ($41–$99 to $84 ($49–$119 million. Of these, the presenteeism accounted for 42% to 52%.Conclusions: The results suggest that an improvement in the controlling of asthma could have a

    1990-10-10

    ICG Utilities applied before the Alberta Public Utilities Board for determining a rate base and for fixing and approving interim and final rates for gas supplied to its customers in Alberta. A hearing was held to consider issues related to the application. In determining the rate base, the company's capital expenditures, acquisition of reserves, capitalization of administrative expenses, accumulated depreciation and related expense, and necessary working capital were taken into account. The fair return on the rate base was then fixed by considering the company's capital structure, long- and short- term debt rates, return on common equity, and foreign exchange rates. Utility revenue requirements were discussed in terms of cash operating expenses, cost of gas, income taxes, and non-cash operating expenses. Other matters treated at the hearing were the allocation of costs among ICG and affiliated companies, proposed amendments to ICG standards, regulations and practices, and the hearing costs reserve account. 5 tabs.

    2007-01-01

    The Alberta Soil Science Workshop is held annually in order to provide a forum for the discussion of issues related to soil sciences in Alberta. Attendees at the conference discussed a wide range of subjects related to soil sciences and measuring the environmental impacts of oil and gas activities in the province. The role of soil science in sustainable forest management was also examined. Issues related to acid deposition were reviewed, and recent developments in soil chemistry analysis for agricultural practices were discussed. Other topics included wildland soil analysis methods; the long-term impacts of sulphate deposition from industrial activities; and water chemistry in soils, lakes and river in the Boreal regions. Projects initiated to assess cumulative land use impacts on rangeland ecosystems were outlined along with a review of tools developed to optimize soil analysis techniques. One of the 46 presentations featured at this conference has been catalogued separately for inclusion in this database. refs., tabs., figs

  3. Management of routine solution gas flaring in Alberta

    International Nuclear Information System (INIS)

    1998-01-01

    Alberta's Clean Air Strategic Alliance (CASA) shares decision-making responsibilities with the Government of Alberta for strategic aspects of air quality. In 1997, the Alliance established the Flaring Project Team to develop recommendations that address potential and observed impacts associated with flaring, with particular focus on 'upstream solution gas' flaring. The upstream industry explores for, acquires, develops, produces and markets crude oil and natural gas. Essentially, solution gas at upstream sites is 'co-produced' during crude oil production. The project team was established to collect and summarize information on flaring and its impacts and to develop recommendations for short-term actions to minimize the practice of routine flaring of solution gas. Another goal of the team is to develop a research strategy to better understand flaring emissions and their effects on human, animal and environmental health. The team is working on developing long-term strategies for actions to address the gas flaring issue. 5 refs., 1 tab., 7 figs

    2009-06-15

    Public concern over global warming has led to many political attacks on the oil industry, particularly Alberta's tar sand industry. This document focused on security issues in northern Alberta and reviewed past incidences of security threats. The likelihood of sabotage to wells, pipelines, buildings, and other industry facilities was assessed. Five potential sources of opposition were identified, notably individual saboteurs, eco-terrorists, mainstream environmentalists, First Nations, and the Metis people. All except the Metis have at various times used some combination of litigation, blockades, boycotts, sabotage, and violence against economic development projects. This report stated that although such incidents will likely continue in the future, it is unlikely that extra-legal obstruction will become widespread unless these various groups cooperate with each other. Since these groups have different social characteristics and conflicting political interests, it is unlikely that such cooperation will occur. 34 refs.

  5. A forward look at power prices in Alberta

    International Nuclear Information System (INIS)

    Reid-Carlson, D.

    1999-01-01

    The various components of the price of electricity, various rate design methodologies, and factors that influence cost-of-service such as types of generation and fuel, age of the physical plant, size of utility, rate of customer and load growth, funding arrangements, tax status, customer mix, and load profile are examined in an effort to predict the future price of electricity in Alberta. The prediction is that delivered prices will increase across all sectors, albeit at levels less than the increase would be without competition. Alberta pool prices in the longer term will continue to reflect the marginal cost of the last generators dispatched to meet the demand. Convergence between electricity spot prices and natural gas prices is predicted to occur over time

    2005-07-01

    Aboriginal issues present risks and challenges to resource development in Alberta. This paper provided an overview of significant precedents and acts which may impact on oil and gas activities. The Constitution Act of 1982 acknowledged that existing Aboriginal and treaty rights of the Aboriginal peoples of Canada were recognized and confirmed. In the case of R v. Sparrow, justification was established where there was a valid legislative objective, such as conservation and resource management, and a precedent was set regarding the interpretation of disputes of section 35 subsection 1 concerning legal restriction of the exercise of treaty rights, such as hunting and fishing. In R v. Badger, the Supreme Court of Canada (SCC) advised that the framework applied to treaty rights as well as Aboriginal rights. The Natural Resources Transfer Agreement transferred powers over natural resources from Canada to Alberta in relation to hunting rights. Proof of rights issues were discussed in Taku River Tlingit First Nation v. Tulesequa Chief Mine Project, as well as in Haida Nation v. British Columbia, where it was concluded that an Aboriginal right need not be proven before a duty to consult arises. A review of Alberta's consultation practices was presented, as well as the Aboriginal issues and resource development initiative, which recognizes the importance of consultation with affected Aboriginal people and communities when regulatory and development activities infringe their existing treaty and other constitutional rights, such as the rights to hunt, fish and trap for food. Details of the Consultation Coordination Group were presented. A draft of the Government of Alberta's First Nations Consultation Policy on Land Management and Resource Development was also presented. tabs, figs.

    Verma, M.; Cook, T. [United States Geological Survey, Denver, CO (United States). Central Region

    2010-09-15

    This paper presented a reserve growth study that was conducted on oil pools in Alberta, Canada. Historical oil reserve data were evaluated to assess the potential for future reserve growth in both pools and fields, and reserve growth models and functions were developed to better forecast hydrocarbon volumes. The study also considered the sensitivity of reserve growth to such factors as pool size, porosity, and oil gravity. From 1960 to 2005, the reported known recoverable oil in Alberta, excluding the Athabasca oil sands and including only pools with adequate data, increased from 4.2 to 13.9 billion barrels of oil (BBO). New discoveries contributed 3.7 BBO and reserve growth added 6 BBO. Most reserve growth occurred in pools with more than 125,000 barrels of oil. Light-oil pools account for most of the total known oil volume and consequently showed the lowest growth. Pools with greater than 30 percent porosity grew more than pools with lower porosity reservoirs. Oil field growth was found to be almost twice that of pool growth, possibly because the analysis evaluated fields with two or more pools discovered in different years. The growth in oil volumes in Alberta pools is projected to be about 454 million barrels of oil in the period from 2006 to 2010. Over a 25-year period, the cumulative reserve growth in Alberta oil pools was substantially lower than other major petroleum-producing regions, but the growth at the field level compares well. 8 refs., 2 tabs., 9 figs.

  10. CO2 in Alberta - a vision of the future

    International Nuclear Information System (INIS)

    Edwards, K.

    1999-01-01

    The potential to develop a province-wide infrastructure for carbon dioxide (CO 2 ) collection and transmission was discussed. The petroleum industry's original interest in CO 2 was its potential for enhanced oil recovery (EOR) for Alberta's depleted oil fields. However, new interest has stemmed from its perceived role in global climate change and the potentially negative business and economic implications of emitting CO 2 into the atmosphere. It was suggested that the development of a province wide infrastructure to collect CO 2 would address both interests. A simple screening of the reservoirs was carried out to determine if Alberta has the right oil reservoirs and sufficient CO 2 supplies to support a large-scale CO 2 infrastructure. The proposed infrastructure would consist of CO 2 supplies from electrical power generation plants, CO 2 trunklines, feeder pipelines to deliver CO 2 from the trunklines to the field and the oil reservoirs where the CO 2 would be injected. Such infrastructures already exist in Texas and Mexico where more than 1 billion scf per day of CO 2 is used for EOR. This study compared the factors leading to a large-scale CO 2 industry with factors in place during the 1970s and 1980s, when most of the hydrocarbon miscible floods were initiated in Alberta. It was concluded that the preliminary economics suggest that the concept has merit. 12 refs., 3 tabs., 9 figs

  11. Alberta Energy and Utilities Board, regulatory highlights for 1998

    International Nuclear Information System (INIS)

    1999-01-01

    This new publication informs readers about what the Alberta Energy and Utilities Board (EUB) did in the past year, including important regulatory issues, trends and initiatives. The EUB is an agency of the provincial government, established to regulate Alberta's energy resource and utility sectors. It is part of the Alberta Ministry of Energy. The four main functions of the Board are regulatory initiatives, license applications, enforcement and information. This publication summarized the EUB's position regarding flaring (both solution gas flaring and well test flaring), and Board activities in the areas of animal health concerns, the gas over bitumen controversy, the deregulation of the electric industry and what it means to the EUB, improvements in data quality as a result of improved industry compliance in reporting, and a variety of issues related to the oil sands and the negotiated settlement process. Also, the Board has been proactive in the area of oilfield waste management guidelines, proliferation policies for gas processing facilities, sulphur recovery guidelines, and the expansion of the orphan well program to include facilities and pipelines. As a measure of the success of the EUB, a recent survey of 19 randomly selected focus groups praised EUB for its impartiality, fair and equitable enforcement and independence. It was also praised for its technically competent and experienced staff, its access to quality information and the clarity of its mandate, regulatory requirements and processes. The Board's efforts in the area of timely stakeholder consultation was highlighted. tabs., figs

    Alberta's oil sands contain an estimated crude bitumen-in-place of nearly 2.5 trillion barrels. Production has increased to the point where it has overtaken non-conventional sources, and is expected to reach more than 2 million barrels per day by 2012, and over 5 million barrels per day by 2030. Although it is assumed that most of this production will be marketed in the United States, the industry is facing many constraints that could affect potential crude oil production and existing market share. The Asian-Pacific region is an obvious new market for Canadian heavy oil and bitumen due to an increasing demand for petroleum products in that region and the potential for reaching the California market with the same pipeline. This paper examined the following three criteria that will determine the success of any initiative to move Canadian crude oil to Asian-Pacific markets: (1) a sustainable supply of crude from Alberta; a pipeline to transport the crude to a deepwater port on the west coast; and, a guaranteed market at the other end. The feasibility of marketing Alberta heavy oil and bitumen to Asia was also discussed. 12 refs., 1 tab., 8 figs

    Mental illness has been widely cited as a driver of costs in the criminal justice system. The objective of this paper is to estimate the additional mental health service costs incurred within the criminal justice system that are incurred because of people with mental illnesses who go through the system. Our focus is on costs in Alberta. We set up a model of the flow of all persons through the criminal justice system, including police, court, and corrections components, and for mental health diversion, review, and forensic services. We estimate the transitional probabilities and costs that accrue as persons who have been charged move through the system. Costs are estimated for the Alberta criminal justice system as a whole, and for the mental illness component. Public expenditures for each person diverted or charged in Alberta in the criminal justice system, including mental health costs, were $16,138. The 95% range of this estimate was from $14,530 to $19,580. Of these costs, 87% were for criminal justice services and 13% were for mental illness-related services. Hospitalization for people with mental illness who were reviewed represented the greatest additional cost associated with mental illnesses. Treatment costs stemming from mental illnesses directly add about 13% onto those in the criminal justice system. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The government of Alberta deregulated its electric power industry to introduce industry structure and regulatory reforms that would promote competitive electricity prices. The objective was to ensure fairness for customers and generating facilities. A graph depicting power pool prices shows the reality of soaring prices at the onset of deregulation in Alberta. Today, there remains uncertainty in the development of retail choice, additional rate riders, new generation, transmission expansion, other jurisdictions and future prices. Consumers are still poorly equipped to make decisions and farmers have no means of protection from fluctuating electricity prices. They see deregulation as a complete failure because costs are up and benefits are nowhere to be seen. Ontario can learn from the Alberta experience by adopting the recommendations to set financial penalties for incompetence, financial compensation to customers for errors, and to be fully ready with systems tested ahead of deregulation. Anticipated customer benefits should be clearly identified in advance. The future electric power industry in Ontario needs vision, stability, a cohesive plan, and leadership devoid of complacency. 1 fig.

    The roles, responsibilities and objectives of ESBI, a private for-profit company, appointed by the Alberta Government to be the Independent Transmission Administrator in the province, is sketched, prior to a discussion of price volatility in electricity, Alberta interconnections, intertie issues, the economic theory and the reality impact on prices. Given that imports and exports constitute a relatively small proportion of total generation or load in Alberta, price volatility is considered to have been only minimally affected by imports/exports. In contrast, transmission constraints, i.e. the limits on physical capacity of the existing transmission system to accommodate all desired transactions, have significant impact on imports/exports. Factors underlying constraints and price volatility such as uncertainty of generation dispatch, leading to reduced interest to invest, which in turn leads to scarce capacity for imports/exports, and the actions required to reduce uncertainty and address other issues such as congestion management, tariff design and the creation of regional transmission organizations, are also discussed to provide further clarification of the issues. It is suggested that these and other related issues need to be resolved to provide the clarity around transmission access and the tools required to manage price fluctuations

  17. Bloody Lucky: the careless worker myth in Alberta, Canada.

    2012-01-01

    As the Canadian province of Alberta has adopted neoliberal prescriptions for government, it has increasingly attributed workplace injuries to worker carelessness. Blaming workers for their injuries appears to be part of a broader strategy (which includes under-reporting injury levels and masking ineffective state enforcement with public condemnation of injurious work) to contain the potential political consequences associated with unsafe workplaces. This reflects the state's sometimes conflicting goals of maintaining the production process and the political legitimacy of the government and the capitalist social formation. This case study considers the political dynamics of occupational health and safety in Alberta to understand the escalating use of the careless worker myth over time. Alberta's emphasis on employer self-regulation has resulted in a large number of annual workplace injuries. The 2008 "Bloody Lucky" safety awareness campaign intensified this attribution of blame via gory videos aimed at young workers. This case study examines the validity of this attribution to reveal that this campaign provides workers, particularly young workers, with inaccurate information about injury causation, which may impede their ability and motivation to mitigate workplace risks.

    The community consultation process was examined with reference to natural gas from coal (NGC) development in Alberta. It was suggested that NGC has a huge potential in Canada, and can be developed in an environmentally responsible manner which considers all stakeholders. However, water supply shortages and the effects of development on groundwater remain key stakeholder concerns in Alberta. Issues concerning water protection and handling were discussed, along with issues concerning surface disruption during resource development activities. An outline of road needs and pipeline corridors was presented. An outline of a typical NGC compressor station were given. Issues concerning public anxiety over air quality were discussed with reference to flaring and landowner complaints. It was noted NGC is not sour and contains no liquid hydrocarbons or foreign contaminants. A review of government regulations and best practices was presented with regards to flaring. Multi-stakeholder advisory committee practices were reviewed. It was concluded that Alberta is currently using a variety of consultation processes to enable better communications between industry and stakeholders. figs

    1992-01-01

    To assess the future conventional crude oil supply potential in Alberta, a modelling system was designed with the capacity to determine the fraction of existing and potential reserves which could prove technically, economically and/or commercially viable over time. The reference case analysis described assumed constant real oil prices and fiscal burdens, capital and operating costs. Reserve additions from new pool discoveries were summed with reserves from existing pools to arrive at an estimate of the potential supply of established reserves in each play area. The established reserves from all plays were then totalled to provide the provincial conventional oil resource potential. Alberta's recoverable conventional crude oil reserves were shown to be declining at about 2 percent per year. However, even with declining recoverable reserves and relatively low prices, the results of the study indicated that the conventional oil industry remained a major revenue generator for the province and would continue to be so over the next 15 to 20 years. Improved operating efficiencies, cost reductions, reasonable prices and cooperation between industry and government were shown to be necessary to assure the continued viability of Alberta's conventional oil industry. figs., tabs., 11 refs

    A detailed study was conducted to evaluate the gas production decline rates in Alberta. The study examined the producing gas wells that were place in production between 1990 and 1997. Three major assumptions were used to determine the number of wells necessary to meet future market demand. These were: (1) reserves have been declining at greater rates in the past several years. The current rate of decline is 12 per cent, (2) new reserves added in future will produce at 5.1 E6M3 per year, and (3) the decline rates for new gas wells will be 27 per cent in the first year, 16 per cent in the second year, 12 per cent in the third year and thereafter. With this information, the Alberta Energy and Utilities Board estimates that the annual total deliveries of gas from Alberta in the year 2002 will be 177.4 E9M3 compared to 127 E9M3 in 1997. In order to meet this supply, drilling activity for successful gas wells will have to double the 1997 rate because it is predicted that more than 6400 new wells will be needed per year to meet future demand. 2 refs., 2 tabs., 20 figs

    The Bozeman Quadrangle, Montana, was evaluated to identify and delineate areas containing environments favorable for uranium deposits. This evaluation was conducted using methods and criteria developed for the National Uranium Resource Evaluation program. General surface reconnaissance, mapping, radiometric traverses, and geochemical sampling were performed in all geologic environments within the quadrangle. Aerial radiometric and HSSR data were evaluated and followup studies of these anomalies and most of the previously known uranium occurrences were conducted. Detailed gravity profiling was done in the Tertiary Three Forks-Gallatin Basin and the Madison and Paradise Valleys. Also, selected well waters were analyzed. Eight areas are considered favorable for sandstone uranium deposits. They include the Tertiary Three Forks-Gallatin basin, the Madison and Paradise Valleys, and five areas underlain by Cretaceous fluvial and marginal-marine sandstones. Other environments within the quadrangle are considered unfavorable for uranium deposits when judged by the program criteria. A few environments were not evaluated due to inaccessibility and/or prior knowledge of unfavorable criteria

    An outstanding goal in speciation research is to trace the mode and tempo of the evolution of barriers to gene flow. Such research benefits from studying incipient speciation, in which speciation between populations has not yet occurred, but where multiple potential mechanisms of reproductive isolation (RI: i.e., premating, postmating-prezygotic (PMPZ), and postzygotic barriers) may act. We used such a system to investigate these barriers among allopatric populations of Drosophila montana. In all heteropopulation crosses we found premating (sexual) isolation, which was either symmetric or asymmetric depending on the population pair compared. Postmating isolation was particularly strong in crosses involving males from one of the study populations, and while sperm were successfully transferred, stored, and motile, we experimentally demonstrated that the majority of eggs produced were unfertilized. Thus, we identified the nature of a PMPZ incompatibility. There was no evidence of intrinsic postzygotic effects. Measures of absolute and relative strengths of pre- and postmating barriers showed that populations differed in the mode and magnitude of RI barriers. Our results indicate that incipient RI among populations can be driven by different contributions of both premating and PMPZ barriers occurring between different population pairs and without the evolution of postzygotic barriers. © 2014 The Author(s).

  7. Advantage or illusion: is Alberta's progress sustainable?

    A new indicator of economic and environmental well-being, the Genuine Progress Indicators, of GPI, is discussed as part of an attempt to gauge the state of health of Alberta's economy, and to establish whether the tremendous apparent economic progress made by the province in recent decades is real or illusory. The GPI, an accounting system by which nations can measure real progress and real wealth, was developed by the Pembina Institute for Appropriate Development of Alberta. It combines 51 indicators of economic, social and environmental measures, and is consistent with international efforts to find new measures of well-being and human development. Based on a study using the GPI system, real disposable income of Albertans was 5.5 per cent lower in 1999 than in 1982, despite a 36.3 per cent rise in Alberta's GDP per capita. This finding suggests that not all people are sharing in the the economic good times. Personal and household debt has also risen substantially and now exceeds real disposable income for the first time in history. Ability to save has been squeezed, resulting in protracted decline in personal savings, while Albertans pay 500 per cent more taxes in real dollars since 1961. Social and human health indicators highlight signs of social stress, such as rising levels of divorce, problem gambling and falling voter participation. Other indicators raise concerns about the condition of Alberta's natural capital, such as forests, agricultural soils, air and water quality, fish, wildlife and protected areas. Environmental GPIs show that Albertans have the fourth-highest ecological footprint in the world, exceeded only by the Arab Emirates, Singapore and the United States. The bigger the footprint the more is someone else on the planet shortchanged. The Pembina Institute report concludes that the development of Alberta's fossil fuel energy resources has come with a tremendous ecological price tag. It also shows that conventional crude oil

    Full Text Available Woodland caribou conservation has been the topic of much debate for the past few decades. By the late 1970s there was growing concern about declining woodland caribou populations and the interaction between industrial activities and woodland caribou. Initial concerns led to the closure of the licensed hunting season in 1981. Early confrontation between government and industry in the late 1980s transformed into a series of evolving collaborative ventures. Improving our understanding of the basic ecology of woodland caribou in Alberta was at the center of early research efforts; more recent studies have examined the effects of industrial activities on caribou and effectiveness of various mitigation factors. Despite having amassed an impressive body of information from a research and monitoring perspective, progress on implementing effective management actions has been less dramatic. Industry has endured significant costs implementing a variety of perceived conservation initiatives, but caribou populations continued to decline through the last few decades. While some parties feel more research is needed, there is growing consensus that changes to habitat as induced by human activities are important factors influencing current caribou declines. Predation is a proximate cause of most caribou mortality. Climate change mediated alterations to habitat and predator-prey interactions remain a key source of uncertainty relative to future caribou population trends. Management actions will need to deal with long term habitat changes associated with human land use and short term implications of increased predation. In 2005, the provincial minister responsible for caribou conservation responded to the draft 2004 recovery plan and created the Alberta Caribou Committee (ACC. The goal of the ACC is to maintain and recover woodland caribou in Alberta’s forest ecosystems while providing opportunities for resource development, following guidance provided by the

  9. Enhancing the Alberta Tax Advantage with a Harmonized Sales Tax

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available Alberta enjoys a reputation as a fiercely competitive jurisdiction when it comes to tax rates. But the reality is that the province can do better with a tax mix that has greater emphasis on consumption, rather than income tax levies. While Alberta has a personal tax advantage compared to other Canadian jurisdictions — but not the United States — it relies most heavily on income taxes and non-resource revenues that impinges on investment and saving. Taxes on new investment in Alberta’s non-resource sectors are no better than average, compared to other countries in the Organization for Economic Cooperation and Development, or OECD, so it is not exceptionally attractive to many different kinds of investors. And Alberta’s corporate income tax rate is not much more competitive than the world average for manufacturing and service companies. By introducing the Harmonized Sales Tax with a provincial rate of 8 per cent (in addition to the federal 5 per cent rate, Alberta has the ability to make its tax system more competitive. An HST would even allow the province to entirely eliminate income tax for the majority of families. And because the HST would be easily administered using the same collection mechanisms that already exist for the GST, implementing a new Alberta HST could be done relatively smoothly and with minimal additional administration costs. Adopting an Alberta HST is the simplest, most efficient and fairest way to reform the provincial tax system, and will deliver noticeable benefits to Albertans, most visibly in the form of significant income tax relief. It would enable the province to raise the income-tax exemption from $17,593 to $57,250, making it possible for couples to earn up to $114,500 free of any provincial income taxes. In addition, the province could lower income tax rates for income over that amount from 10 to nine per cent. And with the revenue from the HST, Alberta would have the capacity to lower its general corporate

    Uranium resources in the Lewistown Quadrangle, Montana, were evaluated to a depth of 1500 m (5000 ft). All existing geologic data were considered, including geologic surveys, literature, theses, radiometric surveys, oil- and water-well logs. Additional data were generated during the course of two field seasons, including the collection of more than 350 water, rock, crude oil and panned concentrate samples for analyses, sedimentary facies maps, structural geology and isopach maps, and field examination of reported areas of anomalous radioactivity. Three environments with potential for the occurrence of a minimum of 100 t of 0.01% U 3 O 8 were delineated. The most favorable environment is located in the southeastern portion of the quadrangle; here, Tertiary felsic dikes intrude four potential sandstone host rocks in the Kootenai Formation and the Colorado Shale. Structural-chemical traps for allogenic uranium are provided by the juxtaposition of oil-bearing domes. A second potential environment is located in the Eagle Sandstone in the northwestern and western portions of the quadrangle; here, anomalous water samples were obtained downtip from oxidized outcrops that are structurally related to Tertiary intrusive rocks of the Bearpaw and Highwood Mountains. Lignitic lenses and carbonaceous sandstones deposited in a near-shore lagoonal and deltaic environment provide potential reductants for hexavalent uranium in this environment. A third environment, in the Judith River Formation, was selected as favorable on the basis of water-well and gamma-ray log anomalies and their structural relationship with the Bearpaw Mountains. Organic materials are present in the Judith River Formation as potential reductants. They were deposited in a near-shore fluvial and lagoonal system similar to the depositional environment of the Jackson Group of the Texas Gulf Coast

  13. Evolution of bow-tie architectures in biology.

    Directory of Open Access Journals (Sweden)

    Tamar Friedlander

    2015-03-01

    Full Text Available Bow-tie or hourglass structure is a common architectural feature found in many biological systems. A bow-tie in a multi-layered structure occurs when intermediate layers have much fewer components than the input and output layers. Examples include metabolism where a handful of building blocks mediate between multiple input nutrients and multiple output biomass components, and signaling networks where information from numerous receptor types passes through a small set of signaling pathways to regulate multiple output genes. Little is known, however, about how bow-tie architectures evolve. Here, we address the evolution of bow-tie architectures using simulations of multi-layered systems evolving to fulfill a given input-output goal. We find that bow-ties spontaneously evolve when the information in the evolutionary goal can be compressed. Mathematically speaking, bow-ties evolve when the rank of the input-output matrix describing the evolutionary goal is deficient. The maximal compression possible (the rank of the goal determines the size of the narrowest part of the network-that is the bow-tie. A further requirement is that a process is active to reduce the number of links in the network, such as product-rule mutations, otherwise a non-bow-tie solution is found in the evolutionary simulations. This offers a mechanism to understand a common architectural principle of biological systems, and a way to quantitate the effective rank of the goals under which they evolved.

    On 6 July 2017, a Mw 5.8 earthquake occurred 11 km southeast of Lincoln, Montana. The event was widely-felt from Edmonton, Alberta, Canada (750 km north), Seattle, Washington (800 km west), the Idaho/Utah and Idaho/Nevada borders (550 km south), and Rapid City, South Dakota (750 km east). This is the largest earthquake to occur in the state since the 1959 M 7.3 Hebgen Lake event 250 km to the southeast. In the three weeks following the 6 July 2017 Mw 5.8 main shock, the U.S. Geological Survey and Montana Bureau of Mines and Geology located more than 300 aftershocks. Preliminary observations show most of these aftershocks form a short NNE zone that suggests that the main shock may have slipped on a NNE left-lateral fault. A smaller number of aftershocks extend along a longer WNW-trending zone. These faults are part of the Lewis and Clark line, a prominent zone of Middle Proterozoic to Holocene age strike-slip, dip slip, and oblique slip faulting trending 400 km east-southeast from northern Idaho to east of Helena, Montana, and terminating southeast of this earthquake. We use identified aftershock waveforms as templates to examine the data from 1 June 2017 through 27 July 2017 with cross-correlation techniques on nearby permanent and temporary seismic stations deployed shortly after the mainshock to identify foreshocks and additional small aftershocks. Locating these events allows us to study subsurface geology, map fault structures, and provide insight on the spatial and temporal evolution of the earthquake sequence, which may continue to produce aftershocks for years. Other notable earthquakes in the region include a damaging M 6.6 earthquake 100 km to the south in June 1925, M 6.2 and M 6.0 earthquakes near Helena, Montana in October 1935 that caused significant damage and four fatalities, and a M 5.6 earthquake 170 km to the south in July 2005 that caused minor damage in Dillon and the surrounding region. We hope this work not only allows us to map the involved

SETTING--Two teaching and three district general hospitals in the midlands, Wales, and north England. SUBJECTS--15 registrars and senior registrars. INTERVENTIONS--A swab soaked in sterile saline was taken from specific area on ties at end of first and third working days and sent in transport medium for culture on chocolatised blood and MacConkey agar for 48 hours. MAIN OUTCOME MEASURES--Level of bacteriological growth assessed semiquantitatively (0 for no contamination; for heavy contamination) after swabs had been cultured. At end of study the participants completed a questionnaire to assess their attitude toward wearing different types of necktie. RESULTS--12 doctors (80%) completed the study. Although bow ties were significantly less contaminated at end of first working day (z = -2.354, p = 0.019), this difference was not maintained; there was no difference in level of contamination on third day. Level of contamination did not increase between first and third day of wearing the same garment. One of the 10 doctors who returned the questionnaire found the bow tie very uncomfortable. All participants would consider wearing a bow tie if it proved to be less contaminated than a conventional tie. CONCLUSIONS--Although a significant difference in contamination was established between conventional and bow ties on first day of study, this difference was not confirmed on third day and there is unlikely to be any real association between tie type and bacterial contamination. Because of its negative image and difficulty to tie, the bow tie will probably remain a minority fashion. Images p1583-a PMID:8292945

  5. Potential for enhanced geothermal systems in Alberta, Canada

    International Nuclear Information System (INIS)

    Hofmann, Hannes; Weides, Simon; Babadagli, Tayfun; Zimmermann, Günter; Moeck, Inga; Majorowicz, Jacek; Unsworth, Martyn

    2014-01-01

    The province of Alberta has a high demand of thermal energy for both industrial and residential applications. Currently, the vast majority of the heat used in these applications is obtained by burning natural gas. Geothermal energy production from deep aquifer systems in the sedimentary basin could provide an alternative sustainable source of heat that would significantly reduce greenhouse gas emissions. To date there has been no geothermal field development in Alberta because the average geothermal gradient was considered to be too low for economic geothermal energy generation. However, with new technologies for Enhanced Geothermal Systems (EGS), it may be possible to develop geothermal resources from the sedimentary rocks in the Western Canadian Sedimentary Basin (WCSB). A numerical feasibility study based on a regional geological model and existing and newly gained data was conducted to identify scenarios for geothermal energy production in the region. In central Alberta, three Devonian carbonate formations (Cooking Lake, Nisku, Wabamun) and the Cambrian Basal Sandstone Unit were identified as the highest geothermal potential zones. Thermal-hydraulic reservoir simulations for a 5 km × 5 km site in the city of Edmonton were performed to evaluate reservoir development concepts for these four potential target formations; therefore, hydraulic fracturing treatments were also simulated. Different utilization concepts are presented for possible applications of geothermal energy generation in residential, industrial and agricultural areas. The Cooking Lake formation and the Basal Sandstone Unit are potentially the most promising reservoirs because the most heat can be extracted and the applications for the heat are widespread although the costs are higher than utilizing the shallower formations. Reservoir stimulation considerably improves the economics in all formations

  6. Preventing Domestic Violence in Alberta: A Cost Savings Perspective

    Directory of Open Access Journals (Sweden)

    Lana Wells

    2012-06-01

    Full Text Available Recent studies show that Alberta has the fifth highest rate of police reported intimate partner violence and the second highest rate of self reported spousal violence in Canada, and despite a 2.3 percent decline over the last decade, the province’s rate of self-reported domestic violence has stubbornly remained among the highest in Canada; rates of violence against women alone are 2.3 percentage points higher than the national average. In fact, every hour of every day, a woman in Alberta will undergo some form of interpersonal violence from an ex-partner or ex-spouse. Besides the devastating toll that domestic violence has on victims and their families, the ongoing cost to Albertans is significant. In the past five years alone it is estimated that over $600 million will have been spent on the provision of a few basic health and non health supports and that the majority of this cost ($521 million is coming out of the pockets of Albertans in the form of tax dollars directed at the provision of services. Fortunately, investment in quality prevention and intervention initiatives can be very cost effective, returning as much as $20 for every dollar invested. Recent research on preventative programming in the context of domestic violence shows promising results in reducing incidents of self-reported domestic violence. The economic analysis of this preventative programming suggests that the benefits of providing the various types of programming outweighed the costs by as much as 6:1. The potential cost savings for the Alberta context are significant; the implementation of these preventative programs has been estimated to be approximately $9.6 million while generating net cost-benefits of over $54 million. Domestic violence is a persistent blight, and continues to have a significant impact on individuals and families in Alberta, but potent tools exist to fight it. This brief paper offers a cogent summary of its costs, and the benefits that could be

  7. Recommendations and final report on the Alberta transmission administrator function

    Billinton, R.; Wallace, R.B.

    1997-01-01

    In May 1995, the Electric Utilities Act (EUA) was passed formalizing the Alberta government's policy of electric industry restructuring. The Act established two new important market entities: a power pool and a transmission administrator (TA). Combined, these two entities create the open access required to enable competition in generation. Functionally, the TA acts as a single transmission service agent for all transmission wire owners. The TA leases the wires from owners then provides a province-wide tariff schedule for transmission services to recover the required revenue. Customers can only purchase transmission service from the TA. Both the lease wire cost and the TA tariff schedule must be approved by the regulator

  8. Alberta's economic development of the Athabasca oil sands

    Science.gov (United States)

    Steinmann, Michael

    This dissertation examines the 61-year evolution of public policies pertaining to development of Alberta's non-conventional source of crude oil. The Athabasca oil sands contain an estimated 1.5 trillion barrels and provide for a safe continental supply. The Provincial Government first sponsored this undertaking in 1943. The period from then to 1971 was one of a transition from a wheat economy to a natural-resource economic base. A stable government emerged and was able to negotiate viable development policies. A second period, 1971 to 1986, was marked by unstable world conditions that afforded the Alberta government the ability to set terms of development with multi-national oil firms. A 50% profit-sharing plan was implemented, and basic 1973 terms lasted until 1996. However, 1986 was a critical year because the Organization of Petroleum Exporting Countries (OPEC) reduced prices, causing the Alberta economy to lapse into recession. During a third period, 1986 to 1996, the Alberta Government was unable to adapt quickly to world conditions. A new leadership structure in 1996 made major changes to create ongoing fiscal and development policies. That history provides answers to two primary research questions: How do public policies affect the behaviors of the modern corporation and visa versa? What are the implications for development theory? Two sources of information were used for this study. First, it was possible to review the Premier's files located in the Provincial Archives. Materials from various government libraries were also examined. Some 7,000 documents were used to show the evolution of government policymaking. Second, interviews with leaders of oil companies and federal research facilities were important. Findings support the thesis that, to facilitate oil sands development, government and the private sector have closely collaborated. In particular, revenue policies have allowed for effective R&D organization. Relying on intensive technological

    The purpose is to determine the feasibility of applying high- resolution reflection seismic surveying to coalbed methane (CBM) exploration and development. Numerical reflection seismic methods are examined for measuring the mapping continuity and coherence of coal zones. Numerical modelling of a coal zone in Upper Cretaceous sediments near Willow Creek, Alberta indicates that seismic data that is predominantly of 100 Hz is required to map the coal zone and lateral facies variations within the deposit. For resolution of individual coal seams, a central frequency >150 Hz would be needed. 26 refs., 17 figs., 3 tabs.

    2007-01-01

    There are considerable differences between international heavy oil and Alberta oil sands projects, notably the high viscosity of the bitumen in the oil sands reservoirs. The oil sands bitumen do not flow to wells without heating the bitumen, thereby adding to the already high cost of Alberta oil sand operations. This report provided an economic comparison of Alberta oil sands and international heavy oil projects. It also included a brief scoping review to compare with conventional oil regimes. Full exploration costs including the costs of dry holes were allocated to conventional oil operations in order to obtain a proper comparison. This investigation included the costs of dry holes. The report was a follow up to an earlier study released on April 12, 2007 on the preliminary fiscal evaluation of Alberta oil sand terms. The report provided an economic framework and described project selection. It then provided a discussion of production, costs and price data. Four adjusted projects were presented and compared with Alberta. The Venezuelan royalty formula was also discussed. Last, the report provided a detailed fiscal analysis. Comparisons were offered with Cold Lake and Athabasca Mine. A review of some other fiscal systems applicable to conventional oil were also outlined. It was concluded that Alberta oil sands developments are very competitive. It would be possible to modestly increase government revenues, without affecting the international competitive position of Alberta with respect to conventional oil. There is also some possibility to increase the base royalty on the Alberta oil sands without losing competitiveness. tabs., figs

  15. Redoable Tie-Over Dressing Using Multiple Loop Silk Threads

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available After skin grafting, to prevent hematoma or seroma collection at the graft site, a tie-over dressing has been commonly used. However, although the conventional tie-over dressing by suture is a useful method for securing a graft site, refixation is difficult when repeated tie-over dressing is needed. Therefore, we recommend a redoable tie-over dressing technique with multiple loops threads and connecting silk threads. After the raw surface of each of our cases was covered with a skin graft, multiple loop silk thread attached with nylon at the skin graft margin. We applied the ointment gauze and wet cotton/fluffy gauze over the skin graft, then fixed the dressing by connecting cross-counter multiple loop thread with connecting silk threads. When we opened the tie-over dressing by cutting the connecting silk threads, we repeated the tie-over dressing with the same method. The skin graft was taken successfully without hematoma or seroma collection or any other complications. In conclusion, we report a novel tie-over dressing enabling simple fixation of the dressing to maintain proper tension for wounds that require repetitive fixation. Further, with this reliable method, the skin grafts were well taken.

  16. Tyrosine phosphorylation of Grb14 by Tie2

    Dumont Daniel J

    2010-10-01

    Full Text Available Abstract Background Growth factor receptor bound (Grb proteins 7, 10 and 14 are a family of structurally related multi-domain adaptor proteins involved in a variety of biological processes. Grb7, 10 and 14 are known to become serine and/or threonine phosphorylated in response to growth factor (GF stimulation. Grb7 and 10 have also been shown to become tyrosine phosphorylated under certain conditions. Under experimental conditions Grb7 is tyrosine phosphorylated by the Tie2/Tie-2/Tek angiogenic receptor tyrosine kinase (RTK. Furthermore, Grb14 has also been shown to interact with Tie2, however tyrosine phosphorylation of this Grb family member has yet to be reported. Results Here we report for the first time tyrosine phosphorylation of Grb14. This phosphorylation requires a kinase competent Tie2 as well as intact tyrosines 1100 and 1106 (Y1100 and Y1106 on the receptor. Furthermore, a complete SH2 domain on Grb14 is required for Grb14 tyrosine phosphorylation by Tie2. Grb14 was also able to become tyrosine phosphorylated in primary endothelial cells when treated with a soluble and potent variant of the Tie2 ligand, cartilage oligomeric matrix protein (COMP Ang1. Conclusion Our results show that Grb14, like its family members Grb7 and Grb10, is able to be tyrosine phosphorylated. Furthermore, our data indicate a role for Grb14 in endothelial signaling downstream of the Tie2 receptor.

    International Nuclear Information System (INIS)

    Lauzon, D.

    1997-01-01

    The long-term outlook for Dow Chemical's involvement in Alberta's petrochemical industry was discussed. Dow Chemical Canada is a company with annual sales of more than $20 billion that manufactures and supplies chemicals, plastics, energy, agricultural products, consumer goods and environmental services in 157 countries in the world. Alberta is the centre of growth and development for the Canadian petrochemical industry because of the proximity to feedstocks. Alberta is seen as a good, long-term source of ethane. Dow Chemical intends to continue being a major player in the further development of the industry in Alberta. As proof of that confidence, there are 11 capital projects in progress at Dow's Western Canada Operation, totaling $600 million. An important ingredient of the continuing success of the petrochemical industry in Alberta will be the willingness and ability of the federal and provincial governments to work in partnership with industry to develop support infrastructure and policies

    Full Text Available In this article we intend to approach the discourses as social ties, indicated by Lacan, relating them to the freudian concepts of helplessness (Hilflosigkeit and the malaise of civilization. The theory of discourses opens up a new way of thinking about clinical structures and social ties, by articulating language and enjoyment camps, the subject and the unconscious knowledge. This theory, while it takes over Freudian principles, it advances in impasses left by the Viennese master, in particular on the relationship between the metapsychological foundations of the subjective constitution and the conceptual bases concerning culture and actual social ties.

    A revised Pipeline Regulation has been issued and is currently available on the Alberta Energy and Utilities Board (EUB) website. Changes to the regulation reflect bothchanges in EUB regulatory policy and processes and technological improvements. Goals of the revision include improvements in overall pipeline performance, and the implementation of recommendations derived from the Public Safety and Sour Gas Committee concerning sour gas pipeline safety. The regulation was re-organized for greater clarity, and structured into 11 parts. Issues concerning the transition to the revised regulation were presented. The summary of notable administrative changes included clarifications of when a pipeline application is not required; when ABSA approval is required for steam lines; situations for which low-pressure natural gas lines must be licensed; and emergency response requirements. Technical clarifications include requirements for pipeline operations and maintenance manuals; composite materials; limitations on amounts of H{sub 2}S in polymeric pipe; pressure mismatches; approval for testing with gaseous media; venting of small volumes of raw gas; right-of-way surveillance; inspection of surface construction activities; annual corrosion evaluations; registering of pipelines and excavators in controlled areas with Alberta One-Call; ground disturbance training; restoration and signage maintenance on abandoned pipelines; sour service steel pipelines; unused pipelines and abandoned pipelines; and remediation of stub ends in operating pipelines.

    1985-01-01

    The extinction event at the Frasnian-Famennian boundary cannot be associated with a first-order event, whether impact, volcanic or other. However, data from Alberta and western Australia suggest a sudden flooding of cratonic areas by anoxic water as the immediate or second-order cause. In the Rocky Mountains near Jasper, Alberta abrupt sedimentological, geochemical and faunal changes occur between bioturbated dolomitic siltstones below and thinly laminated, very pyritic, argillaceous lime mudstones above. The siltstones which overlie thick subtidal sediments that infilled Middle Frasnian reef topography, were deposited in shallow, well oxygenated water and contain a Frasnian gigas Zone conodont fauna. In contrast, the overlying lime mudstones which pass upward into beds with Famennian triangularis Zone conodonts, represent deposition under strongly anoxic conditions; the contained pyrite has anomalously high delta/sup 34/S values suggesting prolonged bacterial reduction of sulfate to sulfide. The abrupt change to anoxic conditions could have been triggered by an ocean turn-over event as a result of which cratonic areas were flooded with anoxic water. This in turn would have caused a sharp reduction of the biomass and large-scale faunal extinctions.

  5. Sage-grouse habitat selection during winter in Alberta

    2010-01-01

    Greater sage-grouse (Centrocercus urophasianus) are dependent on sagebrush (Artemisia spp.) for food and shelter during winter, yet few studies have assessed winter habitat selection, particularly at scales applicable to conservation planning. Small changes to availability of winter habitats have caused drastic reductions in some sage-grouse populations. We modeled winter habitat selection by sage-grouse in Alberta, Canada, by using a resource selection function. Our purpose was to 1) generate a robust winter habitat-selection model for Alberta sage-grouse; 2) spatially depict habitat suitability in a Geographic Information System to identify areas with a high probability of selection and thus, conservation importance; and 3) assess the relative influence of human development, including oil and gas wells, in landscape models of winter habitat selection. Terrain and vegetation characteristics, sagebrush cover, anthropogenic landscape features, and energy development were important in top Akaike's Information Criterionselected models. During winter, sage-grouse selected dense sagebrush cover and homogenous less rugged areas, and avoided energy development and 2-track truck trails. Sage-grouse avoidance of energy development highlights the need for comprehensive management strategies that maintain suitable habitats across all seasons. ?? 2010 The Wildlife Society.

    2003-07-01

    This paper presents a brief history of the Alberta Metis Settlements. In 1990, the Metis Settlement Act defined the Metis as a people of Aboriginal ancestry. The mandate of the Alberta Federation of Metis Settlement Associations is to protect settlement lands, and to take legal action against the province for alleged improper handling of subsurface resource revenues regarding the Metis Population Betterment Trust Fund. The Federation also attains local government authority for the Settlements. The Metis resources include game farming and alternative livestock, oil and gas, diamonds, forestry, and agriculture. The main source of economic development is in the oil and gas sector. Before the 1990 Metis Settlement Accord, the only money earned by the Metis from oil and gas development was through employment and surface rights compensation. No benefits were derived from royalties or participation. Since 1990, 265 wells have been drilled on settlement lands, with participation of the Metis General Council in 136 wells. This paper presents the terms of the Metis Development Agreement with reference to: royalties; General Council's participation rights; operating procedures; disposition of production; and, general matters. 6 figs.

    Story of an Alberta farm couple is told, whose farm has been polluted by a nearby oil lease and salt water from the time they purchased the property in 1968, rendering it unusable for farming. Owners of the well first argued that cleaning it up was not their responsibility, and later claiming that they could not afford the cost. After the company went into receivership, the farmer applied to the province's surface rights' advocate, but could not do better than a $3,000 annual award retroactive to 1999, which he rejected. After much legal wrangling as to the ownership of the wells, the receiver, KPMG, turned the wells over to the Alberta Energy and Utilities Board (EUB) in 2002. Finally, in 2003 the EUB promised to ask the industry-funded Orphan Wells Program to permanently abandon the wells and in preparation for reclaiming the land to undertake the necessary tests to determine the scope of the work that needs to be done and the associated costs. It appears that after 35 years of waiting the farm couple will receive justice after all

    2016-01-01

    We use a welfare-based intertemporal stochastic optimization model and historical data to estimate the size of the optimal intergenerational and liquidity funds and the corresponding resource dividend available to the government of the Canadian province Alberta. To first-order of approximation, this dividend should be a constant fraction of total above- and below-ground wealth, complemented by additional precautionary savings at initial times to build up a small liquidity fund to cope with oil price volatility. The ongoing dividend equals approximately 30 per cent of government revenue and requires building assets of approximately 40 per cent of GDP in 2030, 100 per cent of GDP in 2050 and 165 per cent in 2100. Finally, the effect of the recent plunge in oil prices on our estimates is examined. Our recommendations are in stark contrast with historical and current government policy. - Highlights: • Volatile natural resource income requires an intergenerational and liquidity fund. • We use intertemporal stochastic optimization and historical data for Alberta. • The ongoing dividend is 30 per cent of government revenue. • This requires assets of 100 per cent of GDP in 2050 and initial precautionary saving. • The effect of the 2014 plunge in oil prices on our estimates of the funds is examined.

    Five case histories of river channel changes and associated pipeline exposure problems at river and stream crossings in Alberta were discussed with emphasis on the need for proactive inspection. For each case, the different hydrologic and geomorphic factors that resulted in erosion problems were reviewed and the mitigative actions that were taken to solve the problems were described. It was shown that in some cases, there are inherent difficulties in identifying potential erosion problems at the project design stage. It was also demonstrated that systematic monitoring and inspection procedures are useful for planning and implementing remedial measures before problems occur. There are many natural and anthropogenic causes of channel degradation. Upstream progressing degradation is usually the most common problem encountered at pipeline crossings in Alberta. The two main causes are both flood related. They include channel shortening by cutoffs across long meandering loops, and washout of downstream slope controls such as large beaver dams. The five case studies presented in this paper were: (1) North Saskatchewan River crossing near Drayton Valley, (2) Smoky River crossing near Grande Cache, (3) Hells Creek crossing near Grande Cache, (4) Modeste Creek crossing near Breton, and (5) Freeman River crossing near Swan Hills. It was emphasized that pipeline operators must consider past channel changes and geomorphic analysis to predict future channel instability. 15 figs.

    This final report conducted by the Alberta Royalty Review Panel determined that Albertans are not currently receiving their fair share from energy developments within the province. Royalty rates have not kept pace with recent changes in resource development in the province or with changes in world energy markets. It was argued that since Albertans own their resources, the government of Alberta must alter the royalty and tax system in order to ensure that appropriate royalties are paid. An equitable and flexible administrative framework should be developed to maintain the province's competitive edge in the global energy market. It was recommended that total shares for Albertans from oil sands developments be increased from 47 per cent to 64 per cent; conventional oil shares should be increased from 44 per cent to 49 per cent; and shares for natural gas should be increased from 58 per cent to 63 per cent. Target rates were designed to close tax gaps between economic sectors. Simplified royalty frameworks were presented for natural gas and conventional oil categories, as well as for oil sands developments. Increases of $1.9 billion in provincial revenue are anticipated as a result of the increased royalties. 5 tabs., 31 figs

  13. Grasping at Straws: Comments on the Alberta Pipeline Safety Review

    2013-09-01

    Full Text Available The release last month of the Alberta Pipeline Safety Review was meant to be a symbol of the province’s renewed commitment to environmental responsibility as it aims for new export markets. The report’s authors, Group 10 Engineering, submitted 17 recommendations covering public safety and pipeline incidents, pipeline integrity management and pipeline safety near bodies of water — and many of them run the gamut from the obvious to the unhelpful to the contradictory. That the energy regulator ought to be staffed to do its job should go without saying; in fact, staffing levels were never identified as an issue. The recommendation that record retention and transfer requirements be defined for mergers and acquisitions, sales and takeovers is moot. There is no reason a purchasing party would not want all relevant documents, and no real way to enforce transparency if the seller opts to withhold information. Harmonizing regulations between provinces could reduce companies’ cost of doing business, but could also prove challenging if different jurisdictions use performance-based regulations — which is what the Review recommended Alberta consider. This very brief paper pries apart the Review’s flaws and recommends that the province go back to the drawing board. Safety is a serious issue; a genuine statistical review linking pipeline characteristics to failures and risk-mitigation activities would be a better alternative by far.

  14. The need for a marketing strategy for Alberta bitumen

    1993-01-01

    Over the past 15 years, government and industry have invested heavily in research and development of new technology for extracting bitumen from the Alberta oil sands. The results have been a dramatic increase in the fraction of oil sands deposits that could be economically exploited and a drop in production costs. However, no rapid increase in bitumen recovery has been achieved and most new bitumen production projects have been postponed or cancelled. This is the result of very variable prices for bitumen and the inadequacy of a marketing strategy which relies on the sale of raw bitumen. Options such as transport of bitumen to southern markets are limited by the need to reduce bitumen viscosity for pipelining and by the limited market for emulsified or diluted bitumen. Another possible strategy, conversion of the bitumen to synthetic crude oil, is limited by high costs, product characteristics (too much diesel and not enough gasoline), and a market limited to specialized refineries. A third strategy is to convert and refine bitumen to transportation fuels in Alberta, using inexpensive local natural gas, and transporting the products through existing pipeline facilities. 3 figs

    The cost of oil sands projects varies significantly. While costs have escalated considerably over the past few years, oil prices have gone significantly higher. This report provided an economic evaluation of the current fiscal terms applicable to Alberta oil sands. The analysis was done to evaluate the profitability of oil sand projects to investors under current conditions based on the generic royalty regime based on bitumen values. The objective of the royalty review was to determine whether Albertans received a fair share from their oil and gas resources. It discussed the wide variety of oil sands projects in Alberta using five case studies as examples. Cases involving steam assisted gravity drainage (SAGD) operations were assessed for both the Athabasca Mine and Cold Lake. The report provided a discussion of the economic assumptions including economic cases as well as production, costs and price data. It then provided the preliminary results of the economic-fiscal evaluation from the investor perspective including profitability indicators; international comparisons; internal rate of return; and net present value. The government perspective was also discussed with reference to attractiveness indicators; royalties as a percentage of bitumen values; and non-discounted and discounted government take. A royalty and tax feature analysis was also provided. Several issues for possible further review were also presented. tabs

    Social network research emphasizes the access to nonredundant knowledge content that network ties provide. I suggest that some content is more beneficial than others and that tie strength may affect creativity for reasons other than the associated structure. That is, tie strength may affect how individuals process nonredundant knowledge. I investigate 2 types of knowledge content--information (i.e., facts or data) and frames (i.e., interpretations or impressions)--and explore whether tie strength influences their effect on creativity. Drawing on creativity theory, I employ an experimental design to provide greater theoretical clarity and to isolate causality. According to the results from 2 studies, distinct frames received from contacts facilitate creativity, but the effect of distinct information is more complex. When individuals receive distinct information from strong ties, it constrains creativity compared to distinct frames. Content from weak ties appears to facilitate creativity across all scenarios. The results of mediated moderation analysis indicate the effect of framing versus information for strong ties is driven by decision-making time, as an indicator of cognitive expansion.

  18. The Case for a Carbon Tax in Alberta

    Directory of Open Access Journals (Sweden)

    Sarah Dobson

    2015-11-01

    Full Text Available In 2007, Alberta demonstrated that it could be a leader in the effort to reduce greenhouse gas emissions by becoming the first North American jurisdiction to put a price on carbon. Given that the province had long been criticized for its central role in the carbon-based economy, Alberta’s move was important for its symbolism. Unfortunately, the emissions policy itself has delivered more in symbolism than it has in actually achieving meaningful reductions in greenhouse gas emissions. The Specified Gas Emitters Regulation (SGER, as the carbon-pricing system is formally called, has only helped Alberta achieve a three per cent reduction in total emissions, relative to what they would have been without the SGER. And emissions keep growing steadily, up by nearly 11 per cent between 2007 and 2014, with the SGER only slowing that growth by a marginal one percentage point. Alberta’s carbon-pricing policy simply fails to combat emissions growth; the province needs a new one. Lack of progress in reducing emissions appears to be partly attributable to the fact that many large emitters find it more economical to allow their emissions to rise beyond the provincially mandated threshold, and instead are purchasing amnesty at a lower cost through carbon offsets or by paying the levies that the SGER imposes on excess emissions. But it is also partly attributable to the fact that the SGER only applies to large emitters who annually produce 100,000 tonnes of CO2-equivalent all at one site: mainly oil sands operations and facilities that generate heat and electricity. This excludes operations that emit well over that threshold, but across diffuse locations. The transportation sector, which is typically spread out in just such a way, is the third-largest sector for emissions in Alberta. Its emissions are also growing faster than those of the mining and oil and gas sector, even as emissions in the electricity and heat generation sector are actually declining. And

  19. Alberta's economic performance and outlook

    Energy Technology Data Exchange (ETDEWEB)

    2000-07-01

    The economic climate in Alberta is characterized as being strong and vibrant, with an efficient and modern infrastructure, a young, skilled and productive workforce, a competitive business climate, the lowest overall taxes of any of the provinces, a culturally diverse province with a high quality of life and a fiscally responsible government. All of these attributes add up to the 'Alberta Advantage', the campaign slogan used by the Alberta Government to attract business to the province. Economic highlights from 1999 show that Alberta was the fastest growing province in the country, with 38,000 new jobs created, exports of $34.5 billion, the lowest unemployment rate in the country, and leading all provinces in per capita investment. Total GDP in 1998 amounted to $95.8 billion (up from $61.3 billion in 1985). Even more significant is the fact that only 18.5 per cent of GDP was generated from the energy sector in 1998, as opposed to 37.2 per cent in 1985. Real GDP growth in Alberta was 2.3 per cent in 1999, projected at 6.1 per cent for 2000 and 5.2 per cent for 2001. The corresponding figures for Canada as a whole are 4.1, 4.2 and 3.0 per cent, respectively. Except for agriculture and public administration, which declined by 11.9 per cent and 13.4 per cent respectively, all other sectors of the economy showed significant growth during the period of 1993 to 1999. Technology employment grew by six per cent between 1989 and 1999, fully 33 per cent higher than anywhere else in the country. Energy industry revenue increased by 35 per cent from 1998 to 1999 and industry reinvestment was high at 150 per cent of internal cash flow. Total investment in the province amounted to $31.3 billion in 1999; it is expected to top $34.0 billion in 2000. A list of current major investment projects shows a total of 810 projects in all sectors of the economy, with a total value of $61.14 billion dollars. Growth targets include 295,000 new jobs, value added exports to $26 billion

    Enterprise resource planning (ERP) systems represent a major IT adoption decision. ERP adoption decisions, in the chemicals and allied products sectors, were examined between 1994 and 2005. Networks of strong ties and weak ties partners are investigated. Results show that neighbouring companies linked with strong ties can have an influence on organisations making such adoption decision. Past decisions made by major trading partners have a significant influence on the decision to adopt an ERP system for a given organisation. This reflects the complex nature of the knowledge required for such adoption.

Teams of scientists or engineers collaborate on projects using their social networks to gather new ideas and feedback. Here we bridge the literature on team performance and information networks...... by studying teams' problem solving abilities as a function of both their within-team networks and their members' extended networks. We show that, while an assigned team's performance is strongly correlated with its networks of expressive and instrumental ties, only the strongest ties in both networks have...... an effect on performance. Both networks of strong ties explain more of the variance than other factors, such as measured or self-evaluated technical competencies, or the personalities of the team members. In fact, the inclusion of the network of strong ties renders these factors non...

  8. Vibration Analysis for Monitoring of Ancient Tie-Rods

    2017-01-01

    Full Text Available This paper presents an application of vibration analysis to the monitoring of tie-rods. An algorithm for the axial load estimation based on experimentally measured natural frequencies is introduced and its application to a case study is reported. The proposed model of a tie-rod incorporates elastic bed-type boundary conditions that represent the contact between stonework and the tie-rod. The weighed differences between experimentally and numerically determined frequencies are minimized with respect to the parameters of the model, the main being the axial load and the stiffness at the tie-rod/wall interface. Thus, the multidimensional optimization problem is solved. Results are analysed in comparison to a model with simple fixed-end boundary conditions. In addition, the analytical formulation of the problem is delivered.

    1993-01-01

    Alberta Oil Sands Equity (AOSE) manages the Alberta government's equity investments in oil sands and heavy oil projects. AOSE is a 16.74% participant in the Syncrude Project, a 10% participant in the OSLO (Other Six Leases Operation) Commercial Project and the OSLO New Ventures project, and a 24.17% participant in the Lloydminster Bi-Provincial Upgrader. Syncrude produces ca 12% of Canadian crude oil requirements, and AOSE's share yielded $44 million profit for 1992/93, slightly higher than the the $43.3 million the previous year. The OSLO Commercial Project is a proposed commercial oil sands plant with a mine site and extraction plant to be located north of Fort McMurray, and an upgrading facility to be situated north of Edmonton. Work on this project was suspended in early 1992. The OSLO New Ventures project will handle the exploration and development of the remaining five oil sands leases plus the southern portion of Lease 31. As of March 31, 1993, the project owners were considering a commercial demonstration project utilizing dredging and cold-water extraction processes. Two of the owners are unable to provide funding and discussions are under way to resolve the matter and move the program forward. The Lloydminster Bi-Provincial Upgrader opened Noveber 20, 1992, and production has reached 41,000 bbl/d, or 89% of design capacity. The upgrader will increase the value of heavy crude oil and thereby increase its demand. 5 figs., 3 tabs

  10. Family ties and depression across the life course: An Overview

    2012-08-01

    Full Text Available BACKGROUND Family ties in Europe are affected by demographic trends associated with parenting and partnering, such as a decline in fertility, an increase in childlessness, postponement of parenthood and of partnership formation, the rise of "new" relationship forms and divorce rates. It is unclear how the contemporary family structure and composition are associated with people's mental wellbeing. OBJECTIVE This article examines how ties with parents, siblings, a partner and children are associated with depressive mood of men and women in seven Eastern and Western European countries. METHODS To test our hypotheses we made use of data from the Generations and Gender Surveys. We performed logistic regression analyses to study the associations between people's family ties and depressive mood. RESULTS Our research findings show that family ties can diminish people's depressive feelings. Although we find some gender differences in these associations, we do not find support for the argument that family ties are more important for the mental wellbeing of women than of men. Moreover, our findings support the hierarchical model of family relations in which new ties with partner and children in adulthood gain precedence over the original primary ties with parents and siblings. Finally, we find that the association between family ties and depressive mood is quite similar in Eastern and Western Europe, but being married or having a partner more strongly reduces depressive feelings in Eastern than in Western Europe. CONCLUSIONS Although we did not dispose of longitudinal data, our research results do provide some indications about how demographic changes, for instance, those affecting family size -- the number of children or siblings -- might be associated with mental wellbeing. Our findings also suggest that the demographic trend of increasing partnership dissolution may have larger consequences for people's mental wellbeing in Eastern

    Ruble, James H

    2010-09-01

    Baxter v. Montana (2009 WL 5155363 [Mont. 2009]) is a recent decision from the Montana Supreme Court that provides new legal insight into the societal issue of aid in dying. This case involves interests of persons with terminal illness, medical practitioners, law enforcement, legislative and judicial bodies, as well as the citizens of Montana. A summary judgment ruling at the Montana district court level was based almost entirely on a constitutional fundamental rights analysis. In contrast, the Montana Supreme Court affirming decision was based almost entirely on a statutory rights analysis. Both rulings from the Montana courts support the position that licensed prescribers in Montana who provide aid in dying assistance to terminally ill patients have some immunity from criminal prosecution. Each side in the case argued what they believed to be the intents and purposes of the people of Montana. Baxter v. Montana illustrates different methods to determine the will of the people concerning aid in dying and public policy. This case very subtly suggests a paradigm shift may be occurring in aid in dying policy.

    Full Text Available After skin grafting, to prevent hematoma or seroma collection at the graft site, a tie-over dressing has been commonly used. However, although the conventional tie-over dressing by suture is a useful method for securing a graft site, refixation is difficult when repeated tieover dressing is needed. Therefore, we recommend a redoable tie-over dressing technique with multiple loops threads and connecting silk threads. After the raw surface of each of our cases was covered with a skin graft, multiple loop silk thread attached with nylon at the skin graft margin. We applied the ointment gauze and wet cotton/fluffy gauze over the skin graft, then fixed the dressing by connecting cross-counter multiple loop thread with connecting silk threads. When we opened the tie-over dressing by cutting the connecting silk threads, we repeated the tie-over dressing with the same method. The skin graft was taken successfully without hematoma or seroma collection or any other complications. In conclusion, we report a novel tie-over dressing enabling simple fixation of the dressing to maintain proper tension for wounds that require repetitive fixation. Further, with this reliable method, the skin grafts were well taken.

    2012-03-01

    Retention and recruitment strategies are essential to address nursing workforce supply and ensure the viability of healthcare delivery in Canada. Knowledge transfer between experienced nurses and those new to the profession is also a focus for concern. The Multi-Employer/United Nurses of Alberta Joint Committee attempted to address these issues by introducing a number of retention and recruitment (R&R) initiatives for nurses in Alberta: in total, seven different programs that were introduced to some 24,000 nurses and employers across the province of Alberta in 2001 (the Transitional Graduate Nurse Recruitment Program) and 2007 (the remaining six R&R programs). Approximately 1,600 nurses participated in the seven programs between 2001 and 2009. Of the seven strategies, one supported entry into the workplace, two were pre-retirement strategies and four involved flexible work options. This project entailed a retrospective evaluation of the seven programs and differed from the other Research to Action (RTA) projects because it was solely concerned with evaluation of pre-existing initiatives. All seven programs were launched without a formal evaluation component, and the tracking of local uptake varied throughout the province. The union and various employers faced challenges in implementing these strategies in a timely fashion, as most were designed at the bargaining table during negotiations. As a result, systems, policy and procedural changes had to be developed to support their implementation after they became available.Participants in the programs indicated improvements over time in several areas, including higher levels of satisfaction with work–life balance, hours worked and their current practice and profession. The evaluation found that participation led to perceived improvements in nurses' confidence, greater control over their work environment, decreased stress levels, increased energy and morale and perceived improved ability to provide high-quality care

    This paper reported on a study that presented a preliminary quantitative chemical characterization of Alberta oil sands and many other related Alberta oils such as oil sand bitumen, Cold Lake bitumen, Albian heavy synthetic crude, and Alberta Mixed sweet blend. The rapid increase in production of the Alberta oil sands has resulted in unprecedented environmental concern. The mining, extraction and production of oil sands such resulted in huge consumption of water resources, huge emission of greenhouse gas and large number of tailings ponds. In addition, accidental spills in the transportation and usage of oil sands will potentially cause considerable impact on the environment. It is therefore essential to have the ability to characterize Alberta oil sands and their oil products. The specific chemical properties of the oil sands bitumen must be known. Therefore, this study collected quantitative data on the concentration and distribution profiles of target compounds in Alberta oil sands and its petroleum products. The chemical fingerprints of 5 Alberta oil sands and their related petroleum products were studied using gas chromatography/flame ionization detection (GC/FID) and gas chromatography/mass spectrometry (GC/MS). The characterized hydrocarbons were n-alkanes; target alkylated PAHs and other EPA priority PAHs; biomarker terpanes and steranes; and bicyclic sesquiterpanes. The information acquired during this study will provide the basis for oil-oil correlation and differentiation in future environmental applications relevant to oil sands. 24 refs., 6 tabs., 4 figs.

    This document presents information on the state of reserves, supply, and demand for Alberta's energy resources including bitumen, crude oil, coalbed methane (CBM), conventional natural gas, natural gas liquids, sulphur, and coal. Estimates of initial reserves, remaining established reserves, and ultimate potential were also included, along with a 10-year supply and demand forecast for Alberta's energy resources. The document presents major forecast assumptions that influence Alberta's energy supply and demand. Some of the main variables affecting energy supply and demand include the global oil market, energy prices, Canadian economic performance and the economic outlook for Alberta. The development of Alberta's energy resources depends on reserve supply, costs of development, energy demands, conservation, and social, economic and environmental considerations. In 2004, raw bitumen production continued to grow and accounted for 69 per cent of Alberta's total crude oil and bitumen production. The value-added process of upgrading raw bitumen to synthetic crude oil was also expanded in 2004. Natural gas production from all sources in Alberta increased by 1 per cent compared with 2003. CBM development also increased greatly in 2004. Although it accounted for 80 per cent of the cumulative CBM production to date, it only contributed 0.5 per cent of the provincial total natural gas production. It is expected that CBM development will continue to increase in the coming years. For that reason, a separate estimate of CBM reserves was included. tabs., figs

    A study was conducted to evaluate forest health and tree growth in relation to sulfur deposition in mature and immature lodgepole pine and mature trembling aspen. Soil samples were taken in forests near two sour gas processing plants in west-central Alberta. The soil sample sites were classified into high, medium and low deposition classes. The impact of sulfur deposition on soil and foliar chemistry, tree growth, and forest health was evaluated. The analysis of tree growth, using radial increments, revealed no impact associated with the sulfur deposition class. The only indicators of extensive sulfur impacts on major forest communities detected to date are elevated sulfur concentrations in the surface organic horizon and foliage, the proportion of healthy lodgepole pines, and a depression in the annual specific volume increment. No evidence of widespread forest decline has been found. 42 refs., 35 tabs., 29 figs

  20. Assessment and remediation of earthen pits in Alberta

    Lye, D.E.; Deibert, L.

    1999-01-01

    The proper decommissioning of abandoned earthen pits and the elimination of the associated environmental liabilities were discussed. An earthen pit is an excavated pit used by upstream oil and gas companies to contain/store/burn produced fluids and gases from either gas or oil producing operations. Produced fluids may include liquid hydrocarbons, process chemicals and water originating from oil wells, gas wells, and associated batteries and processing facilities. Improper operation and management at some pits has resulted in soil and/or groundwater contamination. In response to regulatory direction, petroleum operators in Alberta have begun the process of replacing earthen pits with alternative flaring and liquid storage facilities, and embarked on programs to assess, remediate and decommission earthen pits at their operations. This paper describes some of the challenges facing petroleum operators in this regard. It also outlines the regulatory framework within which decommissioning projects must be completed. 2 tabs

  1. The legal framework for wellsite abandonment and reclamation in Alberta

    International Nuclear Information System (INIS)

    Gilmour, B.S.

    1997-01-01

    The legislative framework for wellsite reclamation in Alberta was discussed. The legal requirements that impact on wellsite abandonment and reclamation, with emphasis on the Oil and Gas Conservation Act (OGCA) and the Environmental Protection and Enhancement Act (EPEA) were described. In 1994, the Orphan Well fund was established to ensure that wells are properly abandoned in those cases where participants are insolvent. The fund is financed by the petroleum industry. The regulatory requirements for wellsite abandonment are found in the OGCA and the Well Abandonment Guide 20 which provides explicit procedures for both open-hole and cased-hole abandonment. Liability for contaminated sites exists under the contaminated sites provision of the EPEA. Amendments to the OGCA provide for more supervision over licence transfers and the granting of licences to first-time licensees

  2. Impacts and mitigations of in situ bitumen production from Alberta oil sands

    2010-09-15

    85% or more of Alberta's oil sands is too deep to mine and will be recovered by in situ methods, i.e. from drill holes. This has been made commercially possible through the development in Alberta of Steam Assisted Gravity Drainage (SAGD). Does this impending development threaten the local ecosystem? A quantitative account is given of the principal impacts of in situ oil sands development in Alberta. Impacts on land (habitats), water, and air are considered in terms of local capacity, global benchmarks, and comparisons to alternative renewable technologies. Improvements due to new solvent-additive technology are highlighted.

    Full Text Available Alberta is the wealthiest province in Canada. It is also the only jurisdiction in NorthAmerica where the majority of local library boards charge patrons to use their publiclibraries.There are many reasons why these fees came into being in the 1980s and continue toexist today. Library trustees see them as an easy source of funds for their cashstrappedlibraries, some librarians feel that they help instill a sense of value in librarymaterials and services, library patrons realise the fees are often less than the cost of asingle paperback book and don’t mind paying them.But the main reason the fees still exist is because of the unique form of conservatismespoused by the popular Alberta premier Ralph Klein, who favoured big business, lowertaxes, and privatization of public services while leading the province from 1992 to 2006.Klein’s policies included a focus on user-pay models for all manner of services. Payingfor library cards is something that Alberta’s citizens have accepted for the most part. Butbecause of Alberta’s strong support for user-pay models, this isn’t just an issue for thelibrarians, patrons, and politicians of that province. The possibility also exists thatlibraries in other provinces could be opened up to a GATS challenge by for-profitcorporations outside of Canada because of Alberta’s current user fee policies.How this unique user fee arrangement developed, the current situation, and what thefuture may bring will be the subject of this paper.

  5. Sustainable water management in Alberta's oil sands

    2012-07-01

    The Canadian Association of Petroleum Producers forecast published in 2011 predicts that oil production from oil sands will increase by 50% in the next 3 years and double by 2020. This rate of growth will result in significant pressure on water resources; water use per barrel of oil sands production is comparable to other energy resources - about 2.5 barrels of fresh water per barrel of oil produced are used by mining operations and 0.5 barrels by in-situ operations. Suncor Energy Inc. (Suncor) was the first company to develop the oil sands in northern Alberta and holds one of the largest oil sands positions in Canada. In 2010, Suncor announced plans to increase production to more than 1 million barrels of oil equivalent per day by 2020, which it plans to achieve through oil sands production growth of approximately 10% per year. Because water supply and potential impacts to water quality are critical to its future growth, in 2010-2011 Suncor conducted a risk assessment to identify water-related business risks related to its northern Alberta operations. The assessment identified more than 20 high level business risks in strategic water risk areas including water supply, water reuse, storm water management, groundwater, waste management and river water return. The risk assessment results prompted development of a strategic roadmap to guide water stewardship across Suncor's regional operations. The roadmap describes goals, objectives, and specific activities for each of six key water risk areas, and informs prioritization and selection of prospective water management activities. Suncor is not only exploring water within its own boundaries, but is also collaborating with other oil sands producers to explore ways of integrating its water systems through industry consortia; Suncor is a member of the Oil Sands Leadership Initiative and of the recently formed Canadian Oil Sands Innovation Alliance, among others.

  6. Methane stable isotope distribution at a Carex dominated fen in North Central Alberta

    1999-12-01

    The methane stable isotope distribution was characterized at a Carex dominated fen in boreal Alberta, Canada, over three growing seasons to examine methane production, oxidation, and transport to the atmosphere; processes which are strongly tied to emergent vegetation and the influence of the rhizosphere (upper 20 cm of peat in this system]. At times when standing floodwater was present, δ13C values of emitted methane averaged -63.6 ± 2.3, -66.3 ± 1.6, and -65.4 ± 1.3‰ for the 1994, 1995, and 1996 seasons, respectively. These emissions were significantly 13C depleted relative to the belowground methane dissolved in rhizospheric pore waters, indicating that gas transport in Carex is dominated by passive diffusion. The rhizosphere was 13CH4 enriched relative to depths below the rhizosphere, consistent with the occurrence of root associated methane oxidation, preferential mobilization of 13CH4, and a relatively greater role of acetate fermentation type methane production. Dual isotope tracers, δ13C and δD, help qualify the role of each of these processes and aid in describing the distribution of production pathways, CO2 reduction, and acetate fermentation. Inverse trends in δ13C-CH4 and δD-CH4 depth profiles are consistent with an interpretation suggesting an evolution toward methane production by CO2 reduction with increasing depth. A shift in production mechanisms appears to be the dominate process affecting the stable isotope distribution below 10 cm in the peat column, while oxidation and transport isotope effects are dominant above 10 cm. To test several hypotheses regarding the effects of transport, oxidation, and production on methane isotope distributions, we also present measurements from sites fertilized and sites devegetated (continually clipped) over the 3 year period. Removal of vegetation quickly halted rhizospheric methane oxidation and gas transport while gradually increasing the relative role of CO2 reduction in net methane production as

  9. The Spontaneous Combustion of Railway Ties and Asphalt Shingles

    Science.gov (United States)

    Leslie, Geoffrey

    Many Low Carbon Fuels (LCFs) present unknown spontaneous combustion risks, which must be quantified before their use as fossil fuel replacements. Wood and coal spontaneous combustion is well understood; however, LCFs weather, and subsequent chemical changes could affect their spontaneous combustion properties. LCF spontaneous combustion could lead to accidental fires with possible loss of life, limb and property. The spontaneous combustion risks of two LCFs, discarded creosote-treated wooden railway ties and roofing asphalt shingles, were investigated with calorimetry and heat transfer experiments. Chemical changes due to weathering were studied with pyrolysis-Gas Chromatography/Mass Spectrometry (py-GC/MS). Creosote-treated wooden railway tie dust, roofing asphalt shingle particles, poplar wood pellets, and petroleum coke self-heating were studied with isothermal calorimetry. Railway tie dust and asphalt shingle heat transfer were characterized with a guarded hot plate. Petroleum coke self-heating was consistent with coal, while both poplar pellets and railway tie dust were found to be more reactive compared to oven test results of similar materials. The observed increase in reactivity was probably a result of significant moisture contenint in the pellet and railway tie dust. Critical conditions for spontaneous combustion were evaluated with the Frank-Kamenetskii parameter, assuming an ambient temperature of 40°C and constant moisture content. Kamenetskii calculations indicate that a 1.6 m cube of railway tie dust, or a 58 m cube of asphalt particles, would be unstable and combust. LCF chemistry may have been affected by weathering, which would cause chemical changes that affect their spontaneous combustion properties. Therefore, railway tie wood and roofing asphalt shingle chemistry were investigated by identifying products of 250° and 550°C pyrolysis with py-GC/MS. Railway tie wood pyrolyzates did not show signs of weathering; in contrast, asphalt pyrolysis

  10. Erosion of the Alberta badlands produces highly variable and elevated heavy metal concentrations in the Red Deer River, Alberta.

    2017-10-15

    Erosion is important in the transport of heavy metals from terrestrial to fluvial environments. In this study, we investigated riverine heavy metal (Cd, Cu, Hg and Pb) dynamics in the Red Deer River (RDR) watershed at sites upstream (n=2) and downstream (n=7) of the Alberta badlands, an area of naturally high erosion. At sites draining the badlands, total water column Cd, Cu, Hg and Pb concentrations frequently exceeded guidelines for the protection of freshwater biota. Furthermore, peak concentrations of total Cd (9.8μgL -1 ), Cu (212μgL -1 ), Hg (649ngL -1 ) and Pb (361μgL -1 ) were higher than, or comparable to, values reported for rivers and streams heavily impacted by anthropogenic activities. Total suspended solids (TSS) explained a large proportion (r 2 =0.34-0.83) of the variation in total metal concentrations in the RDR and tributaries and metal fluxes were dominated by the particulate fraction (60-98%). Suspended sediment concentrations (C sed ) and metal to aluminum ratios were generally not indicative of substantial sediment enrichment. Rather, the highly variable and elevated metal concentrations in the RDR watershed were a function of the high and variable suspended sediment fluxes which characterize the river system. While the impact of this on aquatic biota requires further investigation, we suggest erosion in the Alberta badlands may be contributing to Hg-based fish consumption advisories in the RDR. Importantly, this highlights a broader need for information on contaminant dynamics in watersheds subject to elevated rates of erosion. Copyright © 2017 The Authors. Published by Elsevier B.V.

  11. Alberta Oil Sands Equity annual report, 1991-92. Partnership and progress in Alberta's oil sands development

    International Nuclear Information System (INIS)

    1992-01-01

    Alberta Oil Sands Equity (AOSE) manages the Alberta government's equity investments in oil sands and heavy oil projects. AOSE is a 16.74% participant in the Syncrude Project, a 10% participant in the OSLO (Other Six Leases Operation) Commercial Project and the OSLO New Ventures project, and a 24.17% participant in the Lloydminster Bi-Provincial Upgrader. Syncrude produces over 11% of Canadian crude oil requirements, and AOSE's share yielded $43.3 million profit for 1991/92, down significantly from the $82.1 million the previous year due to lower oil prices. The OSLO Commercial Project is a proposed commercial oil sands plant with a mine site and extraction plant to be located north of Fort McMurray, and an upgrading facility to be situated north of Edmonton. Work on this project was suspended in early 1992. The OSLO New Ventures project will handle the exploration and development of the remaining five oil sands leases plus the southern portion of Lease 31. As of March 31, 1992, the project owners were considering a commercial demonstration project utilizing dredging and cold-water extraction processes. Two of the owners are unable to provide funding and discussions are under way to resolve the matter and move the program forward. The Lloydminster Bi-Provincial Upgrader was nearly 90% complete in March 1992 and full startup is expected in November 1992; engineering work was completed in March 1991. The upgrader will increase the value of heavy crude oil and thereby increase its demand. 4 figs., 4 tabs

    Image coregistration is an important step in SAR interferometry which is a well known method for DEM generation and surface displacement monitoring. A practical and widely used automatic coregistration algorithm is based on selecting a number of tie points in the master image and looking for the correspondence of each point in the slave image using correlation technique. The characteristics of these points, their number and their distribution have a great impact on the reliability of the estimated transformation. In this work, we present a method for automatic selection of suitable tie points that are well distributed over the common area without decreasing the desired tie points' number. First we select candidate points using Harris operator. Then from these points we select tie points depending on their cornerness measure (the highest first). Once a tie point is selected, its correspondence is searched for in the slave image, if the similarity measure maximum is less than a given threshold or it is at the border of the search window, this point is discarded and we proceed to the next Harris point, else, the cornerness of the remaining candidates Harris points are multiplied by a spatially radially increasing function centered at the selected point to disadvantage the points in a neighborhood of a radius determined from the size of the common area and the desired number of points. This is repeated until the desired number of points is selected. Results of an ERS1/2 tandem pair are presented and discussed.

    1992-01-01

    It is exceedingly difficult to demonstrate definitive long-term changes in animal health as a result of acid-forming emissions from sour gas wells. A summary is presented of current research in Alberta, followed by the potential for research funding by the Alberta Government/Industry Acid Deposition Program (ADRP). The Alberta Environment research budget consists of four programs in addition to the ADRP: acid deposition effects research in the Athabasca oil sands; western and northern Canada long-range transport of air pollutants; departmental monitoring; and inhalation toxicology and animal health. Animal health research, although a component of the acid deposition issue, is beyond the mandate of Alberta Environment, and the ADRP members committee does not forsee becoming involved in the long-term and complex research required to address the effects of acid-forming emissions on livestock. Funds for additional animal health research must come from other government departments and agencies whose mandate covers this area

  1. Is the restructuring of Alberta's power market on the right track? Evaluating Alberta's first two years of deregulation

    2003-07-01

    The performance of Alberta's restructured electricity market was evaluated since its move to wholesale competition in January 2001. This paper presents the following eight conclusions that the authors arrived at following the evaluation: (1) To meet growing demand, the electricity prices in Alberta would have increased regardless of the type of environment (regulated or not). Capacity investment was required, and it was believed that moving to competition was the best way to attract investors. (2) Success in attracting private investment was attained as a result of Alberta's open market. It has restored reliability of supply and moderated prices. (3) Price comparisons must take into account what the prices would have been if the market had remained regulated. Due to unique generation costs and regulatory environments, comparisons with other regulated jurisdictions is inappropriate. (4) Convergence with other energy rates that would have been seen under regulation is being noted with respect to Alberta's market prices. (5) Under deregulation, prices increase according to the need for new investment and fall after the investment is made. Alberta has been on a path toward continued reduction in wholesale prices since 2001. (6) The non-price benefits of restructuring include improved generation efficiency, captured residual value from regulated assets, and shifting investment risk of new capacity additions from consumers to generators. (7) Downward pressure on prices was noted as a result of deregulation, as expected. (8) Significant value for consumers was captured through Alberta's restructuring process. 7 tabs., 7 figs.

    2002-09-01

    Alberta and Alaska both have an economy based largely on natural resources. The cyclical nature of their economies poses a challenge to stability and sustained prosperity. During the oil crisis of 1973-1974, Alberta and Alaska began receiving oil and gas royalties. The idea of an endowment-type fund began taking shape. This fund would assist in the gradual transition from dependence on non-renewable resources to the responsible management of these resources. Both the Alberta Heritage Savings Trust Fund and the Alaska Permanent Fund were created in 1976. The governments of both jurisdictions set aside revenues from natural resource royalties to provide economic stability. Both jurisdictions followed different policies in terms of management, structure, governance, and objectives. In this paper, the authors compared both funds, examining the policy options which had an impact on their growth and successes. The results showed that in Alaska, monies are paid directly to eligible persons, while allocation decisions in Alberta have been made by the government. The government manages the fund in Alberta, while in Alaska, the fund is managed by a separate entity. The Alaskan fund continues to grow, while the the size of the Alberta fund has remained unchanged for a number of years and is not growing. 21 refs., 5 figs.

  5. Successful and unsuccessful attempts to resolve caribou management and timber harvesting issues in west central Alberta

    Directory of Open Access Journals (Sweden)

    David Hervieux

    1996-01-01

    Full Text Available Research studies of woodland caribou in west central Alberta began in 1979 in response to proposed timber harvesting on their winter ranges. Using results from initial studies, timber harvest guidelines were developed. A recent review of these guidelines, and the assumptions on which they were based, has resulted in a renegotiation by government and industry of timber harvesting on caribou range in west central Alberta. Caribou range in west central Alberta overlaps many jurisdictional boundaries: federal and provincial lands, four Forest Management Agreement Areas, three Alberta Land and Forest Service Regions and two Alberta Fish and Wildlife Service Regions. This jurisdictional complexity in combination with other factors such as total allocation of the timber resources, high levels of petroleum, natural gas and coal extraction activities, a high level of concern by public groups for caribou conservation and recent understanding of woodland caribou needs for abundant space has made resolution of caribou/timber harvest conflicts exceedingly slow and often relatively unproductive. This paper reviews 10 years of trying to resolve conflicts between timber harvesting and caribou conservation through meetings, committees, integrated resource planning, policy papers and public consultation. We describe what might be learned by other jurisdictions that are trying to resolve similar caribou/timber harvesting issues. We conclude with an overview of recent timber harvest planning initiatives on caribou range in west central Alberta.

  6. Sulphur output from oil sands : dramatically changing Alberta's sulphur balance

    Energy Technology Data Exchange (ETDEWEB)

    D' Aquin, G. [Con-Sul Inc., Bigfork, MT (United States)

    2008-07-01

    This paper discussed sulphur production from Alberta's gas and oil sands industries. While sulfur derived from natural gas production in the province is expected to decline as natural gas reserves diminish, Alberta's oil sands contain high amounts of sulphur. It is not yet known how much sulphur will be produced from the province's oil sands facilities. Alberta had considerable stockpiles of sulphur in the 1970s. By 1980, inventories began to decline. By 1996, output had increased to 7.1 million tonnes. Alberta's sulphur inventory reached 9.7 million tonnes following the collapse of the Soviet Union's government mandated fertilizer industry. In 2006, sulphur supplies in Alberta reached 12 million tonnes. Reduced global output has now lowered sulphur stockpiles. Increases in sulphur prices tend to reduce market demand, and lower prices will not typically change the volume of sulphur produced as a byproduct of oil and gas operations. Bitumen-derived sulphur output is expected to exceed gas-derived sulphur output in the near future. Sulphur from oil sands processing is expected to increase by 5 million tonnes by 2017. Increased sulphur production levels in Alberta will present a significant challenge for all sectors of the hydrocarbon industry. It was concluded that developing a plan for storing, selling or disposing of the sulphur will help to ensure the profitability of oil sands operations.

  7. DIGITAL PRESERVATION OF THE QUON SANG LUNG LAUNDRY BUILDING, FORT MACLEOD, ALBERTA

    P. Dawson

    2017-08-01

    Full Text Available This paper describes the results of an emergency recording and archiving of a historic structure in Southern Alberta and explores the lessons learned. Digital recording of the Quon Sang Lung Laundry building in Fort Macleod, Alberta, was a joint initiative between Alberta Culture and Tourism and the University of Calgary. The Quon Sang Lung Laundry was a boomtown-style wood structure situated in the Fort Macleod Provincial Historic Area, Alberta. Built in the mid-1800s, the structure was one of the four buildings comprising Fort Macleod’s Chinatown. Its association with Chinese immigration, settlement, and emergence of Chinese-owned businesses in early twentieth-century Alberta, made the Quon Sang Lung Laundry a unique and very significant historic resource. In recent years, a condition assessment of the structure indicated that the building was not safe and that the extent of the instability could lead to a sudden collapse. In response, Alberta Culture and Tourism engaged the Departments of Anthropology and Archaeology and Geomatics Engineering from the University of Calgary, to digitally preserve the laundry building. A complete survey including the laser scanning of all the remaining elements of the original structure, was undertaken. Through digital modeling, the work guarantees that a three-dimensional representation of the building is available for future use.

    A history of the deregulation schedule in Alberta was presented. The spot market in the province opened in January 1996. What Albertans wanted from deregulation was a competitive power generation market, a liquid spot market, a liquid forward market, competitive retail market, a clear transmission policy, transparent pricing, and innovation. They got a competitive power generation market and a liquid spot market, but with few buyers and an unclear transmission policy with only medium transparency in prices. Innovation was seen in the form of small power and distributed generation such as wind energy. In 2001, the Alberta government stepped in to subsidize consumers because wholesale prices were trading at record highs. In 2002 wholesale prices collapsed. It was shown that prices have declined in Alberta as supply and demand came into balance. The Keephills Generating Plants 3 and 4 will have a large impact on the market in 2005. It was emphasized that new transmission would unlock additional potential market for Alberta generation. The paper presented viewgraphs showing existing generation capacity and the high Alberta prices following deregulation. It was noted that commodity cycles dominate growth plans in the electric power industry. The four generation markets in Alberta were identified. The lesson learned from past experience is that price signals will attract new generators to the market and that government leadership must be consistent. 4 tabs., 6 figs

    This paper describes the results of an emergency recording and archiving of a historic structure in Southern Alberta and explores the lessons learned. Digital recording of the Quon Sang Lung Laundry building in Fort Macleod, Alberta, was a joint initiative between Alberta Culture and Tourism and the University of Calgary. The Quon Sang Lung Laundry was a boomtown-style wood structure situated in the Fort Macleod Provincial Historic Area, Alberta. Built in the mid-1800s, the structure was one of the four buildings comprising Fort Macleod's Chinatown. Its association with Chinese immigration, settlement, and emergence of Chinese-owned businesses in early twentieth-century Alberta, made the Quon Sang Lung Laundry a unique and very significant historic resource. In recent years, a condition assessment of the structure indicated that the building was not safe and that the extent of the instability could lead to a sudden collapse. In response, Alberta Culture and Tourism engaged the Departments of Anthropology and Archaeology and Geomatics Engineering from the University of Calgary, to digitally preserve the laundry building. A complete survey including the laser scanning of all the remaining elements of the original structure, was undertaken. Through digital modeling, the work guarantees that a three-dimensional representation of the building is available for future use. This includes accurate 3D renders of the exterior and interior spaces and a collection of architectural drawings comprising floor plans, sections, and elevations.

    A new car in operation of only 8,000 km, because of malfunction, resulting in lost control and rammed into the edge of the road, and then the basic vehicle scrapped. According to the investigation of the site, it was found that the tie-rod of the car had been broken. For the subjective analysis of the accident and identifying the true causes of rupture of the tierod, a series of studies, from the angle of theory to experiment on the bended broken tie-rod, were conducted. The mechanical model was established; the stability of the defective tie-rod was simulated based on ANSYS software. Meanwhile, the process of the accident was simulated considering the effect of destabilization of different vehicle speed and direction of the impact. Simultaneously, macro graphic test, chemical composition analysis, microstructure analysis and SEM analysis of the fracture were implemented. The results showed that: 1) the toughness of the tie-rod is at a normal level, but there is some previous flaws. One quarter of the fracture surface has been cracked before the accident. However, there is no relationship between the flaw and this incident. The direct cause is the dynamic instability leading to the large deformation of impact loading. 2) The declining safety factor of the tie-rod greatly due to the previous flaws; the result of numerical simulation shows that previous flaw is the vital factor of structure instability, on the basis of the comparison of critical loads of the accident tie-rod and normal. The critical load can decrease by 51.3% when the initial defect increases 19.54% on the cross-sectional area, which meets the Theory of Koiter.

    Full Text Available Sepsis, a dysregulated host response to infection that causes life-threatening organ dysfunction, is a highly heterogeneous syndrome with no specific treatment. Although sepsis can be caused by a wide variety of pathogenic organisms, endothelial dysfunction leading to vascular leak is a common mechanism of injury that contributes to the morbidity and mortality associated with the syndrome. Perturbations to the angiopoietin (Ang/Tie2 axis cause endothelial cell activation and contribute to the pathogenesis of sepsis. In this review, we summarize how the Ang/Tie2 pathway is implicated in sepsis and describe its prognostic as well as therapeutic utility in life-threatening infections.

    Although crystalline silica has been recognized as a health hazard for many years, it is still encountered in many work environments. Numerous studies have revealed an association between exposure to respirable crystalline silica and the development of silicosis and other lung diseases including lung cancer. Alberta Jobs, Skills, Training and Labour conducted a project to evaluate exposure to crystalline silica at a total of 40 work sites across 13 industries. Total airborne respirable dust and respirable crystalline silica concentrations were quite variable, but there was a potential to exceed the Alberta Occupational Exposure Limit (OEL) of 0.025 mg/m(3) for respirable crystalline silica at many of the work sites evaluated. The industries with the highest potentials for overexposure occurred in sand and mineral processing (GM 0.090 mg/m(3)), followed by new commercial building construction (GM 0.055 mg/m(3)), aggregate mining and crushing (GM 0.048 mg/m(3)), abrasive blasting (GM 0.027 mg/m(3)), and demolition (GM 0.027 mg/m(3)). For worker occupations, geometric mean exposure ranged from 0.105 mg/m(3) (brick layer/mason/concrete cutting) to 0.008 mg/m(3) (dispatcher/shipping, administration). Potential for GM exposure exceeding the OEL was identified in a number of occupations where it was not expected, such as electricians, carpenters and painters. These exposures were generally related to the specific task the worker was doing, or arose from incidental exposure from other activities at the work site. The results indicate that where there is a potential for activities producing airborne respirable crystalline silica, it is critical that the employer include all worker occupations at the work site in their hazard assessment. There appears to be a relationship between airborne total respirable dust concentration and total respirable dust concentrations, but further study is require to fully characterize this relationship. If this relationship holds true

    The Alberta oil sands bitumen deposits comprise of one of the largest sources hydrocarbon in the world, and have emerged as the fastest growing, soon to be dominant, source of crude oil in Canada. The oil industry has made great strides in improving the effectiveness of gathering this resource. In particular, alternatives to open-pit mining have been developed which enable in-site recovery of underground deposits with a minimum of environmental disruption. The main challenge that remains is the large quantity of energy needed in the process of extracting the oil and upgrading it to commercial levels. For a typical in-situ extraction project, about 18% of the energy content of the oil produced is used up in the extraction process, while a further 5% is used in generating hydrogen to upgrade the bitumen to synthetic crude oil. Looking ahead, even as improvements in energy use efficiency, (and hydrocarbon use efficiency) counterbalance the increases in hydrocarbon demand from economic growth (particularly in the developing world), Canada and Alberta recognize that the oil sands resource will be needed, and both support the development of this resource in an environmentally responsible way. The large energy requirement for the oil sands extraction process represents a challenge with regard to both environmental impact and security of supply. The use of natural gas, the current energy supply, has impacts in terms of air quality (via NOX and other emissions) and also represents a large greenhouse gas emissions component. As the oil sands industry expands, the availability of natural gas also becomes a concern, as does price and price stability. With this background, the opportunity for nuclear reactors to provide an economical, reliable, virtually zero-emission source of energy for the oil sands becomes very important. Over the last few years, developments in oil sands extraction technology, and developments in CANDU technology through the Advanced CANDU Reactor, (ACR

    Tumor-associated TIE-2-expressing monocytes (TEM) are highly proangiogenic cells critical for tumor vascularization. We previously showed that, in human breast cancer, TIE-2 and VEGFR pathways control proangiogenic activity of TEMs. Here, we examine the contribution of these pathways to immunosuppressive activity of TEMs. We investigated the changes in immunosuppressive activity of TEMs and gene expression in response to specific kinase inhibitors of TIE-2 and VEGFR. The ability of tumor TEMs to suppress tumor-specific T-cell response mediated by tumor dendritic cells (DC) was measured in vitro. Characterization of TEM and DC phenotype in addition to their interaction with T cells was done using confocal microscopic images analysis of breast carcinomas. TEMs from breast tumors are able to suppress tumor-specific immune responses. Importantly, proangiogenic and suppressive functions of TEMs are similarly driven by TIE-2 and VEGFR kinase activity. Furthermore, we show that tumor TEMs can function as antigen-presenting cells and elicit a weak proliferation of T cells. Blocking TIE-2 and VEGFR kinase activity induced TEMs to change their phenotype into cells with features of myeloid dendritic cells. We show that immunosuppressive activity of TEMs is associated with high CD86 surface expression and extensive engagement of T regulatory cells in breast tumors. TIE-2 and VEGFR kinase activity was also necessary to maintain high CD86 surface expression levels and to convert T cells into regulatory cells. These results suggest that TEMs are plastic cells that can be reverted from suppressive, proangiogenic cells into cells that are able to mediate an antitumoral immune response. ©2013 AACR.

    Integrated carbon-to-liquids technology (ICTL) incorporates three basic processes for the conversion of a wide range of feedstocks to distillate liquid fuels: (1) Direct Microcatalytic Coal Liquefaction (MCL) is coupled with biomass liquefaction via (2) Catalytic Hydrodeoxygenation and Isomerization (CHI) of fatty acid methyl esters (FAME) or trigylceride fatty acids (TGFA) to produce liquid fuels, with process derived (3) CO2 Capture and Utilization (CCU) via algae production and use in BioFertilizer for added terrestrial sequestration of CO2, or as a feedstock for MCL and/or CHI. This novel approach enables synthetic fuels production while simultaneously meeting EISA 2007 Section 526 targets, minimizing land use and water consumption, and providing cost competitive fuels at current day petroleum prices. ICTL was demonstrated with Montana Crow sub-bituminous coal in MCL pilot scale operations at the Energy and Environmental Research Center at the University of North Dakota (EERC), with related pilot scale CHI studies conducted at the University of Pittsburgh Applied Research Center (PARC). Coal-Biomass to Liquid (CBTL) Fuel samples were evaluated at the US Air Force Research Labs (AFRL) in Dayton and greenhouse tests of algae based BioFertilizer conducted at Montana State University (MSU). Econometric modeling studies were also conducted on the use of algae based BioFertilizer in a wheat-camelina crop rotation cycle. We find that the combined operation is not only able to help boost crop yields, but also to provide added crop yields and associated profits from TGFA (from crop production) for use an ICTL plant feedstock. This program demonstrated the overall viability of ICTL in pilot scale operations. Related work on the Life Cycle Assessment (LCA) of a Montana project indicated that CCU could be employed very effectively to reduce the overall carbon footprint of the MCL/CHI process. Plans are currently being made to conduct larger

  18. Clean air strategy for Alberta: Report to the ministers

    International Nuclear Information System (INIS)

    1991-11-01

    As a response to continuing discussions on the impact of fossil fuels on global warming, acid deposition, and smog, a clean air strategy consultation program was announced by Alberta's Ministers of Energy and Environment to encourage public discussion on air emissions resulting from the production and use of energy. The consultation program had three objectives: to help identify and clarify the most important issues associated with energy production and use which need to be addressed in developing a clean air strategy; to outline practical and achievable actions which can be taken to reduce emissions; and to develop program and policy recommendations to the provincial government. The consultation program included workshops and regional sessions, as well as background research. The discussions, findings, and conclusions from the program are summarized. Several air quality management challenges were identified, including the need for a more comprehensive system for managing air quality; the priority of local air quality issues and problems; the need to address cumulative regional emissions and impacts; and scientific and economic uncertainties. A number of goals have been developed to address these challenges, such as implementation of a comprehensive air quality management system, identification of cost-effective energy conservation and efficiency opportunities, development of innovative and targeted solutions to manage cumulative emissions, and improvement of the gathering and application of scientific and technical knowledge regarding atmospheric processes and effects. A glossary of terms is included. 12 figs., 17 tabs

    This paper sought to examine which pre- and post-migration factors might be associated with changes in refugees' health status. Using linear regression, the associations between pre- and post-migration factors and changes in self-rated mental and physical health status were examined in 525 refugees from the 1998 Settlement Experiences of Refugees in Alberta study. Having spent time in a refugee camp and having held professional/managerial jobs in one's home country were associated with a greater decline in mental health status since arrival in Canada. Having completed a university degree in one's home country was associated with a greater decline in physical health status. Being employed was associated with greater improvements in mental health status. Perceived economic hardship was associated with greater declines in physical health status. A higher number of settlement services received during the first year in Canada was associated with greater improvements in both mental and physical health status. Longer residence in Canada was associated with greater declines in physical health status but not in mental health status. While little can be done to alter refugees' pre-migration experiences, public policies can affect many post-migration experiences in order to mitigate the negative health consequences associated with resettlement. Results of this study point to the need for continued provision of settlement services to assist refugees with job training, labour market access, and credential recognition, as well as counseling for refugees who experienced the trauma of living in a refugee camp.

    Workplace violence is a significant and widespread public health concern among health care workers, including nurses. With growing awareness of how practice environments influence patient outcomes and the retention of health professionals, it is timely to consider the impact of workplace violence in hospitals. Registered nurses in Alberta and British Columbia, Canada were surveyed on their experiences of violence in the workplace over the last five shifts. Our results suggest that nurses are experiencing many incidences of violence in a given work week, particularly in the emergency, psychiatric, and medical-surgical settings. Most violent acts are perpetrated by patients, but there is also a significant portion of violence and abuse committed by hospital co-workers, particularly emotional abuse and sexual harassment. Our results also indicate that the majority of workplace violence is not reported. We suggest that using the Broken Windows theory might be a useful tool to conceptualize why workplace violence occurs, and that this framework be used to begin to develop new violence prevention policies and strategies.

    1993-01-01

    A description is presented of the environmental impact assessment for an Alberta windfarm, summarizing the rationale, process and results of the assessment, costs involved, and recommendations made. The Pe-kun-nee windfarm was designed as a 44 turbine, 9.9 kW windfarm. The assessment included consideration of the complete range of environmental impacts of the windfarm, including reviews of impacts associated with similar developments elsewhere. From an environmental perspective, the proposed site and transmission line route were exceedingly suitable for development. No major potential impacts were identified. Most impacts that could occur, including terrain and vegetation disturbance, were associated with the construction phase of the project. A series of mitigation measures were developed to minimize each identified impact. Monitoring during the operations phase of the development was recommended to: ensure that the revegetation of disturbed areas was adequate; verify the sound level model; and document the incidence of bird strikes. Potential aesthetic impacts were addressed through a proposed interpretive project designed to educate visitors, enhance the profile of the wind-energy industry, and provide local employment. The assessment was completed within 8 months of initiation at a cost less than $200,000

  2. Electricity market reform failures: UK, Norway, Alberta and California

    2003-01-01

    An analysis of electricity market reforms already taken place in the UK, Norway, Alberta (Canada) and California (USA) leads to our overall conclusion that the introduction of a competitive generation market, of itself, has failed to deliver reliable service at low and stable prices. The market reform failures are attributed to market power abuse by few dominant sellers (especially at times of transmission congestion), poor market design that invites strategic bidding by suppliers, the lack of customer response to price spikes, capacity shortage caused by demand growth not matched by new capacity, and thin trading of forward and futures contracts that are critical for price discovery and risk management. The paper then explains why an electricity market reform can easily fail to deliver the promised gains of better service at lower and more stable prices. The policy implication is that an electric market reform can be extremely risky, and may lead to a disastrous outcome. Thus, it is imprudent to implement such a reform in countries with limited sites for new generation and no indigenous fuels (e.g., Israel and Hong Kong). These countries should therefore consider introducing performance-based regulation that can immediately benefit electricity consumers in terms of lower prices, more stable prices, improved reliability, more choices, while encouraging the electric sector to pursue efficient operation and investment.

    This paper reports that western Canada's biggest sour natural gas, sulfur, and natural gas liquids development project in 2 decades is on target to start up late this year. Shell Canada Ltd.'s $950 million (Canadian) Caroline project will produce 2 tcf of gas and associated products from the Swan Hills member of the middle Devonian Beaverhill Lake group. The price tag will reach about $1 billion, including some start-up costs. The project is designed to process an average 300 MMcfd of gas. It will produce 17,500 b/d of pentanes plus, 4,100 metric tons/day of sulfur, 90 MMcfd of sales gas, and 28,000 b/d of NGL-ethane, propane, and butane. A labor force that is peaking at about 2,400 workers is completing a network of processing plants, about 143 miles of pipeline, three field compressors, and other facilities covering an area of 161 sq miles. Dilcon Constructors Ltd., an arm of Delta Catalytic Corp., Calgary, is the main contractor for the project. About 85% of the services and equipment for Caroline are coming from Alberta suppliers, 7% from suppliers elsewhere in Canada, and only 8% from non-Canadian Sources

  4. The oil and gas industry in Alberta: drilling and production

    2001-11-01

    This document outlined the impacts of drilling and production on the forest structure and integrity. The cumulative impact of all 11,898 wells drilled in 2000 in Alberta, coupled with previously drilled wells that is of primary concern. It is estimated that an 886 square kilometres area of the boreal forest has been cleared as a result of well drilling, based on an assumption of 1 hectare cleared per well site. No regulations govern the reforestation of the areas once the activities have been terminated, and nothing to regulate the cumulative road densities or pipeline densities. A progressive loss and fragmentation of habitat, increased access, and damage to aquatic systems are all consequences of the drilling and production activities. These activities also lead to the contamination of soil and water. Reductions in air quality are associated with drilling and production activities, mainly through the release of various gases in the atmosphere, such as sulphur dioxide and nitrogen dioxide, both responsible for acid rain deposition. Explicit limits on cumulative densities of well sites, pipelines and access roads are part of best practices that can result in a minimization of the negative environmental impacts. Integrated planning with the forest industry, the development and implementation of new operating practices, and a reduction in the pace of development would also go a long way toward the reduction of the ecological footprint

    The Burnt Timber Creek map-area lies in the southern Foothills of Alberta and includes a narrow strip of the Front Range of the Rocky Mts. along its western edge. The area may be divided into 3 principal structural units, underlain from west to east by the McConnell, Burnt Timber, and Fallentimber thrusts, respectively. McConnell thrust underlies the eastern edge of the mountains. Subsidiary folding and faulting are locally evident in the Paleozoic strata above the thrust. Beneath the McConnell thrust, Mesozoic and Paleozoic strata of the Burnt Timber thrust sheet are strongly overturned in the Panther anticline. The axis of this anticline trends northwest. A culmination along it, in the vicinity of Sheep Creek, deforms the McConnel thrust as well. A total of 16 wells have been drilled to date in 4 separate groups. Each group has revealed the presence of gas and 8 of the wells have been capped as potential gas producers. The reservoir rocks are of Mississippian and Devonian age. Shell Panther River No. 1 well (5-19-30-10W5) is remarkable in having tested at about 86% hydrogen sulfide.

    Crandall, G. R.; Kromm, R. B.

    1999-01-01

    This report contains an independent evaluation of the operations of the private marketing agents that are currently marketing the Alberta Crown's share of royalty crude oil. The evaluation includes a review of pricing performance, working relationship, current issues and the overall performance of the marketing arrangements during the fiscal years of 1997 and 1998. Overall, the outsourcing of sales of Crown production to agents is judged to be successful. For example, it has been noted that agents are becoming more aggressive in maintaining and increasing their margins. On the other hand, the increased level of aggressiveness in marketing, while tending to maximize Crown revenues, is also creating a potential conflict on how margins should be shared between the Crown and its agents. Also, there has been evidence of some management issues between the agents and the Crown concerning the extent to which the Crown should share in any increased value which the agent generates by increased third party marketing activities. These differences need to be addressed in order to maintain the strong performance of the marketing program. The consultants also recommend additional guidelines on risk management issues that more clearly define the Crown's risk tolerance. 2 tabs., 4 figs

    A clarification of the ranking of environmentally related claims in bankruptcy and receivership proceedings, was presented. Also, the liability that a creditor assumes when taking control of a debtor's business or assets, particularly where environmental contaminants are concerned, was explained. The way that environmental law operates and the sorts of liability it imposes and upon whom, was also explained. Generally, environmental legislation imposes liability upon the owner of a contaminated property, whether or not the owner caused or created the problem. However, legislation also exists which imposes liability on the party in control and on the party which caused the contamination. A review of cases which deal with environmental legislation and their impact upon receivers in Saskatchewan and Alberta, was presented. Ways in which secured creditors can assess liability and minimize risks, were also described. The proposed amendments to the Bankruptcy and Insolvency Act (BIA) expand the current limited protection from personal liability for trustees in bankruptcy and extend it to receivers, trustees, monitors and agents

For petroleum contaminated soils, the process can bring residual concentration of petroleum below 0.1 percent and polycyclic aromatic hydrocarbon (PAH) concentration to 1--5 ppM. For coal tar contaminated soils, the process can reduce tar concentrations to about 0.05-0.5 percent and the PAH concentration to about 10--60 ppM. Additional post-treatment may be required for some precleaned soils. The process yields by-product agglomerates suitable for combustion in industrial boilers. Light hydrocarbons such as benzene are vaporized from the soil, condensed and collected in the Process and disposed of off-site. The Clean Soil Process has been tested at pilot-plant scale. A conceptual design for a 200-tons-per-day plant yielded a capital cost estimated at $3.1 million with a per-ton operating cost of $40

    Purpose - The purpose of this paper is to apply Bow-tie methodology, a proactive risk assessment technique based on systemic approach, for prospective analysis of the risks threatening patient safety in intensive care unit (ICU). Design/methodology/approach - Bow-tie methodology was used to manage clinical risks threatening patient safety by a multidisciplinary team in the ICU. The Bow-tie analysis was conducted on incidents related to high-alert medications, ventilator associated pneumonia, catheter-related blood stream infection, urinary tract infection, and unwanted extubation. Findings - In total, 48 potential adverse events were analysed. The causal factors were identified and classified into relevant categories. The number and effectiveness of existing preventive and protective barriers were examined for each potential adverse event. The adverse events were evaluated according to the risk criteria and a set of interventions were proposed with the aim of improving the existing barriers or implementing new barriers. A number of recommendations were implemented in the ICU, while considering their feasibility. Originality/value - The application of Bow-tie methodology led to practical recommendations to eliminate or control the hazards identified. It also contributed to better understanding of hazard prevention and protection required for safe operations in clinical settings.

  17. Neural correlates of dynamically evolving interpersonal ties predict prosocial behaviour

    Directory of Open Access Journals (Sweden)

    Johannes Jacobus Fahrenfort

    2012-03-01

    Full Text Available There is a growing interest for the determinants of human choice behaviour in social settings. Upon initial contact, investment choices in social settings can be inherently risky, as the degree to which the other person will reciprocate is unknown. Nevertheless, people have been shown to exhibit prosocial behaviour even in one-shot laboratory settings where all interaction has been taken away. A logical step has been to link such behaviour to trait empathy-related neurobiological networks. However, as a social interaction unfolds, the degree of uncertainty with respect to the expected payoff of choice behaviour may change as a function of the interaction. Here we attempt to capture this factor. We show that the interpersonal tie one develops with another person during interaction - rather than trait empathy - motivates investment in a public good that is shared with an anonymous interaction partner. We examined how individual differences in trait empathy and interpersonal ties modulate neural responses to imposed monetary sharing. After, but not before interaction in a public good game, sharing prompted activation of neural systems associated with reward (striatum, empathy (anterior insular cortex [AIC] and anterior cingulate cortex [ACC] as well as altruism and social significance (posterior superior temporal sulcus [pSTS]. Although these activations could be linked to both empathy and interpersonal ties, only tie-related pSTS activation predicted prosocial behaviour during subsequent interaction, suggesting a neural substrate for keeping track of social relevance.

    Complex problem solving in science, engineering, and business has become a highly collaborative endeavor. Teams of scientists or engineers collaborate on projects using their social networks to gather new ideas and feedback. Here we bridge the literature on team performance and information networks by studying teams' problem solving abilities as a function of both their within-team networks and their members' extended networks. We show that, while an assigned team's performance is strongly correlated with its networks of expressive and instrumental ties, only the strongest ties in both networks have an effect on performance. Both networks of strong ties explain more of the variance than other factors, such as measured or self-evaluated technical competencies, or the personalities of the team members. In fact, the inclusion of the network of strong ties renders these factors non-significant in the statistical analysis. Our results have consequences for the organization of teams of scientists, engineers, and other knowledge workers tackling today's most complex problems.

  4. The power of Alberta business : the impact of electricity deregulation on Alberta small and medium-sized business

    2001-07-01

    Deregulation of the electricity market came into effect on January 1, 2001 in Alberta. This deregulation affects the retail and generation fields of electricity. The intention was to introduce competition and apply downward pressure on electricity prices, but the reverse effect was witnessed: power prices increased. It resulted in a period of anxiety on the part of businesses, caused by the volatility of electricity prices. A survey of Canadian Federation of Independent Business (CFIB) members was conducted in May and June 2001 to better understand the impacts of electricity deregulation on small and medium-sized businesses. A broad range of businesses provided responses (951 responses) covering all sectors of industry and regions in Alberta. A large proportion of respondents were dissatisfied with deregulation, caused in part by the confusion created by the flurry of rebate and credit announcements designed to ease the transition. Small firms were faced with significant increases in electricity prices, and several could not estimate the size of the increase as it was too difficult to measure. Responses varied from a low of 5 per cent increase to a high of 400 per cent in power rates. Most respondents also indicated that the increases had an impact on their business. The impact of power rate increases by sector was examined. Another consequence of deregulation was the fact that billing moved from a single invoice received to the requirement to actively manage energy usage. It was discovered that a lack of information on electricity cost and consumption management impeded the the ability to make business decisions. The CFIB asked respondents to indicate the measures being considered to address management of electricity costs. Incorporating energy-saving devices and/or methods had been considered by slightly more than 40 per cent of respondents. Negotiating with power retailers represented another option under consideration by some. It was felt that government must

    With the decline of conventional oil and gas reserves, natural gas from coal (NGC) is an unconventional gas resource that is receiving much attention from petroleum exploration and development companies in Alberta. Although the volume of the NGC resource is large, there are many challenges facing NGC development in Alberta, including technical and economic issues, land access, water disposal, water diversion and access to information. Exploration and development of NGC in Alberta is relatively new, therefore there is little baseline data on which to base regulatory strategies. Some important information gaps have been filled through water well sampling in coal, mixed coal-sandstone and sandstone aquifers throughout Alberta. Analyses focused on the chemical and physical characteristics aquifers in use for domestic or agricultural purposes. Aquifer depths were generally less than 100 metres. Samples collected from Paskapoo-Scollard Formation, Horseshoe Canyon Formation and Belly River Group aquifers exceed Canadian water quality guideline values with respect to pH, sodium, manganese, chloride, chromium, sulphate, phenols and total dissolved solids. Pump tests conducted within the aquifers indicate that the groundwater flow is complicated. Water quality will have to be carefully managed to ensure responsible disposal practices are followed. Future studies will focus on understanding the chemical and biological process that occur within the aquifers and the possible link between these processes and gas generation. Mitigation and disposal strategies for produced water will also be developed along with exploration strategies using information obtained from hydrogeologic studies. 254 refs., 182 tabs., 100 figs., 3 appendices

  6. Impacts of invasive nonnative plant species on the rare forest herb Scutellaria montana

    2015-11-01

    Invasive plant species and overabundant herbivore populations have the potential to significantly impact rare plant species given their increased risk for local extirpation and extinction. We used interacting invasive species removal and grazer exclusion treatments replicated across two locations in an occurrence of rare Scutellaria montana (large-flowered skullcap) in Chattanooga, Tennessee, USA, to assess: 1) competition by invasive Ligustrum sinense (Chinese privet) and Lonicera japonica (Japanese honeysuckle) and 2) the role of invasive species in mediating Oedocoilus virginianus (white-tailed deer) grazing of S. montana. Contrary to our hypothesis that invasive species presence would suppress S. montana directly via competition, S. montana individuals experienced a seasonal increase in stem height when invasive species were intact but not when invasive species were removed. Marginally significant results indicated that invasive species may afford S. montana protection from grazers, and we suggest that invasive species also could protect S. montana from smaller herbivores and/or positively influence abiotic conditions. In contrast to growth responses, S. montana individuals protected from O. virginianus exhibited a decrease in flowering between seasons relative to unprotected plants, but invasive species did not affect this variable. Although it has been suggested that invasive plant species may negatively influence S. montana growth and fecundity, our findings do not support related concerns. As such, we suggest that invasive species eradication efforts in S. montana habitat could be more detrimental than positive due to associated disturbance. However, the low level of invasion of our study site may not be representative of potential interference in more heavily infested habitat.

    Colorectal cancer surgery includes "high tie" and "low tie"of the inferior mesenteric artery(IMA). However, different ligation level is closely related to the blood supply of anastomosis, which may increase the leakage rate, and it is unclear which technique confers a lower anastomotic leakage rate(AL) and survival advantage. To compare the effectiveness and impact of inferior mesenteric artery (IMA) high ligation versus IMA low ligation on anastomotic leakage, lymph nodes yield rates and 5-year survival. A list of these studies, published in English from 1990 to 2017, was obtained independently by two reviewers from databases such as PubMed, Medline, ScienceDirect and Web of Science. Anastomotic leakage rate, the yield of lymph nodes and 5-year survival were compared using Review Manager 5.3. There was no significant difference in anastomotic leakage, number of lymph nodes retrieved and 5-year survival rate for both techniques. Neither the high tie nor the low tie strategy has an evidence in terms of anastomotic leakage rate, harvested lymph nodes, and the 5-year survival rate. Further RCT is needed.

  8. Independent assessment team report to the Alberta Energy and Utilities Board on implementing deregulation of electricity generation in Alberta

    International Nuclear Information System (INIS)

    1999-01-01

    The particular aspect of deregulation of electricity generation in Alberta discussed is the economics of power purchase agreements (PPAs). There are various parameters associated with the PPAs that are emphasized including: technical characteristics; unit availability, capital costs and O and M costs; coal costs; gas costs; payment for flexible operation; hydro obligation amounts; income tax; property tax; and working capital, insurance and other costs. Chapter one of the Independent Assessment Team (IAT) report covers the report scope, and chapter two describes certain main principles underlying determination of PPAs. Chapter three discusses the IAT's determination of the PPA's forms and their main terms and conditions. Chapter four describes the IAT's determination of the underlying parameter values of the PPAs. Chapter five describes the ITA's determination of the allowed rate of return on equity and the capital structure of PPAs. An appendix covers a detailed description of the consultations carried out by the IAT; a report by HESI on the results of Pool modelling carried out to date (the HESI work was done to assist the IAT in determining PPAs, not the auction design); summary outputs of the IAT's financial model with indicative financial statements for each unit and company under the PPAs; and a document on shared services, common facilities and new units

    The middle Cretaceous in southwestern Montana is composed of a marine and nonmarine succession of predominantly clastic rocks that were deposited along the western margin of the Western Interior Seaway. In places, middle Cretaceous rocks contain appreciable total organic carbon (TOC), such as 5.59% for the Mowry Shale and 8.11% for the Frontier Formation in the Madison Range. Most samples, however, exhibit less than 1.0% TOC. The genetic or hydrocarbon potential (S1+S2) of all the samples analyzed, except one, yield less than 1 mg HC/g rock, strongly indicating poor potential for generating commercial amounts of hydrocarbons. Out of 51 samples analyzed, only one (a Thermopolis Shale sample from the Snowcrest Range) showed a moderate petroleum potential of 3.1 mg HC/g rock. Most of the middle Cretaceous samples are thermally immature to marginally mature, with vitrinite reflectance ranging from about 0.4 to 0.6% Ro. Maturity is high in the Pioneer Mountains, where vitrinite reflectance averages 3.4% Ro, and at Big Sky Montana, where vitrinite reflectance averages 2.5% Ro. At both localities, high Ro values are due to local heat sources, such as the Pioneer batholith in the Pioneer Mountains.

    1976-07-01

    Twenty-one thermal springs in western Montana were sampled for chemical, isotope, and gas compositions. Most of the springs issue dilute to slightly saline sodium-bicarbonate waters of neutral to slightly alkaline pH. A few of the springs issue sodium-mixed anion waters of near neutral pH. Fluoride concentrations are high in most of the thermal waters, up to 18 miligrams per litre, while F/Cl ratios range from 3/1 in the dilute waters to 1/10 in the slightly saline waters. Most of the springs are theoretically in thermodynamic equilibrium with respect to calcite and fluorite. Nitrogen is the major gas escaping from most of the hot springs; however, Hunters Hot Springs issue principally methane. The deuterium content of the hot spring waters is typical of meteoric water in western Montana. Geothermal calculations based on silica concentrations and Na-K-Ca ratios indicate that most of the springs are associated with low temperature aquifers (less than 100/sup 0/C). Chalcedony may be controlling the silica concentrations in these low temperature aquifers even in ''granitic'' terranes.

    Full Text Available Historically, birth rates in Alberta have followed closely the trajectory of change experienced by the other Canadian provinces. Its total fertility rate fell during the low point of the 1930s; it increased during the post-War baby boom in the 1950s and sixties, and thereafter fell to subreplacement levels beginning in the mid 1970s. In recent years, especially since the early 2000s, the birth rate in Alberta has unexpectedly increased, such that by 2007, it had reached 1.90 children per woman - not far from the 2.1 level needed for generational replacement in the long term. During this same period both national and provincial fertility rates fluctuated at levels below those of Alberta (except Saskatchewan and Manitoba, whose rates have been higher. In this study, I examine the historical pattern of fertility change in Alberta, noting similarities and differences with the other provinces. I then look at the association of selected macro level factors (marriage, unemployment, wages, female labour force participation with change in total and parity-specific birth rates between 1997 and 2007, a period of unprecedented economic growth in Alberta. The statistical results show that although marriage is not significantly correlated with change in fertility rates, male and female wages and female labour force participation all show associations consistent with a procyclical interpretation of fertility change - that is, periods of economic growth are conducive to fertility increase whereas bad economic times are associated with reduced fertility.

    This paper reported on a grizzly bear research program that was initiated in the province of Alberta to provide new knowledge and tools to ensure the long term survival of grizzly bears on a multiple use landscape. The Foothills Model Forest (FMF) Grizzly Bear Research Program was formed by scientists from across Canada from a variety of scientific disciplines. A strong partner base has been created to allow the FMF's research efforts to span the entire current distribution of grizzly bear habitat in Alberta. The FMF has provided new large scale seamless maps of grizzly bear habitat and, using detailed grizzly bear GPS movement data, has constructed and tested models that can identify key grizzly bear habitat. This presentation focused on the results of 9 years of applied research and described the new tools and models that are now available to program partners in Alberta. The products are currently being used by both industry and government in Alberta as new standards in landscape management planning in grizzly bear habitat. The author suggested that the approach taken with grizzly bears in Alberta could be used and adapted for a variety of wildlife species in the north. figs.

    Full Text Available In June 2013, heavy rainfall caused flooding on most rivers in the province of Alberta, Canada, producing one of Canada’s most expensive natural disasters with about $6 billion (CDN in damage. Flooding inundated several municipalities including downtown Calgary, the fourth-largest city in Canada. Debris flows and debris floods caused extensive highway closures and damages to development on alluvial fans. Following these events, the Government of Alberta requested an inventory of all fans intersecting municipal development, major roads and highways in Alberta. Such fans may be subject to debris flow, debris flood (mud flows, and/or flood hazards. The study area spans the entirety of the Alberta Rocky Mountains, approximately 51,000 km2 (7% of Alberta. We characterize 710 fans in terms of hazard level and presence and types of elements at risk. We statistically analyse watershed attributes to predict the dominant fan hydrogeomorphic process types. All fans under provincial jurisdiction are assigned priority ratings based on hazard levels and the presence and value of elements at risk. The prioritization is risk-based as it considers both hazards and potential consequences. Of the fans prioritized, 13% intersected parcels containing land and residential developments with an assessed value of $2.4 billion (CDN, and the remainder were crossed by roads, pipelines or transmission lines. We present the study results on an interactive, searchable web application that can support ongoing hazard and risk assessments and risk reduction planning.

    2012-04-01

    Canada's boreal forest resources are coming under increasing pressure from competing land-uses, including establishment of protected areas, and losses of harvestable forest to mining and oil and gas exploration. In the prairie region, concerns about lack of wood supply for pulpmills and potential opportunities for bioenergy production and carbon sequestration for climate change mitigation, have spurred interest in afforestation of marginal agricultural land, notably with fast-growing hybrid poplars (HP). However, global modelling studies suggest that a shift from grassland or crops to forest cover in temperate and boreal regions could result in reduced surface albedo, particularly in winter, causing an increase in radiative forcing and reducing any climate mitigation benefits due to net GHG removal. We report on seven growing seasons of measurements of short-wave canopy albedo using tower-mounted instruments, along with eddy covariance measurements of carbon, water and energy balance, at a site in central Alberta planted with HP cuttings in spring 2005. The data show little systematic change in average albedo as vegetation has changed from bare ground to a plantation of 6 m trees. Reasons for this include very wide (3 m) spacing between the trees, and snow cover which often persists for 4-5 months and is highly visible below the bare canopies during winter. While measurements should continue as the trees grow larger, we postulate that extensive afforestation with HP is unlikely to have major effects on regional-scale surface albedo compared to the agricultural systems they replace. Normal rotation lengths are 15-20 years, hence even if older plantations have significantly lower winter albedo, their contribution to the regional average would be relatively small because they will cover only a small fraction of the landscape (e.g., compared to forests of boreal conifers or temperate broadleaved species).

    In June of 2013, southern Alberta underwent flooding that affected approximately 100,000 people. We describe the process put in place for public health surveillance and assessment of the impacts on health. Public health surveillance was implemented for the six-week period after the flood to detect anticipated health events, including injuries, mental health problems and infectious diseases. Data sources were emergency departments (EDs) for presenting complaints, public health data on the post-exposure administration of tetanus vaccine/immunoglobulin, administrative data on prescription drugs, and reportable diseases. An increase in injuries was detected through ED visits among Calgary residents (rate ratio [RR] 1.28, 95% confidence interval [CI]: 1.14-1.43) and was supported by a 75% increase in the average weekly administration of post-exposure prophylaxis against tetanus. Mental health impacts in High River residents were observed among females through a 1.64-fold (95% CI: 1.11-2.43) and 2.32-fold (95% CI: 1.45-3.70) increase in new prescriptions for anti-anxiety medication and sleep aids respectively. An increase in sexual assaults presenting to EDs (RR 3.18, 95% CI: 1.29-7.84) was observed among Calgary residents. No increases in infectious gastrointestinal disease or respiratory illness were identified. Timely identification and communication of surveillance alerts allowed for messaging around the use of personal protective equipment and precautions for personal safety. Existing data sources were used for surveillance following an emergency situation. The information produced, though limited, was sufficiently timely to inform public health decision-making.

    Full Text Available A study of the respiratory health of grain farmers in Alberta, Canada was carried out in March 2002. Two populations were identified: members, in 1983, of a province-wide farm organisation, and grain farmers registered with the provincial agriculture department. A telephone interview addressed pesticide use (using pre-circulated trade names, chronic disease and respiratory symptoms. Pesticide ingredients were identified from provincial crop protection guides. Total years of use were calculated for seven chemical groups. Consent for linkage to administrative health records was obtained in 2009. A likelihood score (Lscore is computed, relating symptoms to asthma diagnosis. Self-reported asthma and the Lscore are examined against duration of pesticide exposures. Of the 10,767 farmers listed, 2426 were still living, had farmed grain and were interviewed; 1371 were re-contacted and matched to health records. After allowance for confounders, years of exposure to phenoxy compounds are related to self-reported asthma and Lscore. Compared to no exposure, the adjusted odds ratios (95% Confidence Intervals for self-reported asthma for short, medium and long exposure to phenoxy compounds are 1.29 (0.66–2.52, 2.52 (1.25–5.09, and 3.18 (1.54–6.58, and for Lscore are 1.19 (0.91–1.55, 1.50 (1.13–1.99, and 1.58 (1.18–2.12. We conclude that lifetime exposure to phenoxy herbicides is associated with an increased risk of asthma.

  19. Coals to Newcastle: Will Alberta become a crude oil importer?

    The security of markets for Canadian heavy crude oil (HCO) under different conditions is examined. The emphasis of the study is on the conditions under which bitumen blend from Alberta could penetrate certain markets that have generally been identified as potential prospects. A secondary question concerns the cost reductions in bitumen production and upgrading that would be needed for bitumen blend and synthetic crude oil (SCO) to penetrate these same markets if long-term oil prices settle at US$18/bbl for Saudi light delivered to the USA Gulf Coast in 2010. A brief overview is first presented of some of the world and US factors that will affect the demand for Canadian HCO, with specific reference to the demand in the northern USA in 2010. The determination of the volume of HCO that can or will be processed at a refinery or a combination of refineries in a given market is then discussed. The cost and volume numbers for 2010 as provided in the National Energy Board's latest Canadian energy supply and demand forecast are used in the analysis. It is concluded that all traditional markets outside of the Canadian prairies could be lost if world oil prices stay below US$18/bbl for extended periods. At prices below US$17/bbl, bitumen producers would have trouble competing with imported crude oils in Edmonton unless bitumen production costs decline from current levels. The potential for bitumen production costs to decline enough for diluted bitumen to compete with US$18/bbl oil is better than the prospect for SCO costs to decrease enough to compete in eastern Canada or the northern USA at those price levels. 9 figs., 8 tabs

  20. Winter warriors : Alberta company bringing hydronic heating to oilsands

    Energy Technology Data Exchange (ETDEWEB)

    Ball, C.

    2005-10-01

    Hydronic heating systems are expected to become the norm on oilsands construction sites. This article presented an overview of Innovative Climate Solutions Inc. (ICS), an Alberta company who specialize in portable flame-free climate-control systems, and have earned a reputation for staying on the leading edge of technology. ICS has now established a joint venture and local Fort McMurray presence with AirCon Technologies. ICS has focused on portable flame-free heat, concrete curing, grown thawing and drying equipment services. Increasingly drying applications are used year-round to improve project schedules, as these systems can reduce excessive humidity in work environments to improve productivity and safety. Drywall compound, paint and textures cure quickly during cool or damp summer nights, and dry heat also prevents prevents moisture, safeguarding a site against mould. As well as providing solutions to overcome cold weather challenges, ICS-trained climate control consultants work closely with each customer to determine fuel costs, heating needs, and how much equipment is needed. ICS systems output capacity of up to 1.2 million Btu per system, and have the power to thaw 24,000 square feet of ground or cure 36,000 square feet of concrete per system. The design allows one climate-control system to handle the heating needs for an entire construction project, reducing downtime associated with traditional methods of cold-weather construction and preventing emissions risks to workers. The system draws upon a centrally located hydronic water heater which warms a heat-transfer fluid. The fluid is then pumped through a fluid circulation system loop to heat exchangers at remote locations. The systems can run for 125 days between oil changes, with up to 75 hours of run time between re-fuelling. 3 figs.

    2014-07-01

    Full Text Available The problem of low graduation rates at the graduate level has been linked to the challenges of dissertation work. Given that this is a process of “disciplinary enculturation”, where graduate students acquire the ways of being and doing of each discipline, the social relations of doctoral candidates should be analyzed. Several studies have explored the support provided by social ties within academia but have, nevertheless, ignored other spheres. This qualitative study, based on in-depth interviews, explores the personal-sphere social relations in the dissertation writing process from the point of view of doctoral candidates and recent graduates in the fields of Education and Linguistics. Results indicate that the emotional, financial, economic, and academic support offered by these social ties is a necessary, although not in itself, sufficient condition. Some strategies for increasing institutional support to facilitate the process of writing a dissertation are offered.

    1995-01-01

    The most recent and most significant development in the management of PCBs in Canada occurred with the announcement of the Alberta government that it would open its provincial borders to PCB and other hazardous wastes from across Canada for incineration at the province's special waste treatment facility located at Swan Hills, Alberta. The facility has an annual capacity of 15,000 tonnes of PCB waste. Alberta 's own waste products will be treated first; any excess capacity will be utilized to treat waste materials received from other provinces. It is estimated that given the Swan Hills plant capacity, it will take several years to treat and destroy all of Canada's current PCB waste inventory. Regulations concerning transportation, contracting requirements and pricing policies were briefly reviewed

    2001-01-01

    This conference provided to the delegates from across North America a forum where a wide array of perspectives with regard to the new electric market place of Alberta could be discussed. Speakers covered a lot of ground in their examination of the deregulation of the electricity market in Alberta and the impacts felt by consumers and producers alike. The recent events that led to the deregulation were reviewed and an emphasis was also placed on the successful development of power generation projects, wholesale pricing options and independent retail strategies. Open energy markets were discussed in a series of speaker panels where representatives from private organizations added their views on the topic. The conference was divided into seven sessions entitled: (1) the operation of Alberta's market, (2) panel discussion: defending the market, (3) competitive hurdles to successful development, (4) alternative energy solutions, (5) mechanics of retail choice, (6) wholesale pricing options, and (7) independent retailer strategies. refs., tabs., figs

    On the European continent, the price of natural gas is still tied directly and to a great extent to the price of competing energies, especially heavy fuel oil and home heating oil. In other words, the gas market is linked to the oil market. Under the effect of deregulation, this model is likely to change in the future, making a shift like that which took place on the American market in the past. (author)

    Full Text Available Recent bioacoustic investigations have shown that Cicadetta montana Scopoli 1772 is a complex of morphologically similar sister species that are best characterized by their song patterns. At the type locality of C. montana, only mountain cicadas with simple, long lasting song phrases were heard, recorded and collected. Therefore, we have good reasons to suggest that this type of song is characteristic for C. montana s. str. Boulard described a song of C. montana from France with phrases composed of a long and a short echeme; this type of song is characteristic for cicadas morphologically corresponding to C. montana var. brevipennis Fieber 1876; we suggest to raise this taxon to species level. On the basis of specific song, Puissant and Boulard described C. cerdaniensis from Pyrénées. A similar case was the discovery and description of C. montana macedonica Schedl 1999 from Macedonia; since these Macedonian cicadas are sympatric with at least two other cryptic species in the C. montana group and molecular investigations showed substantial genetic differences between C. macedonica and C. montana or C. brevipennis, we conclude that this taxon should also be raised to species level. Songs of closely related C. podolica and Korean mountain cicada are presented as well.Pesquisas recentes de bioacústica mostraram que Cicadetta montana Scopoli 1772 é um complexo de espécie-irmãs morfologicamente semelhantes e melhor caracterizadas por seus padrões de canto. Na localidade-tipo de C. montana somente cigarras serranas de longas frases de canto foram ouvidas, gravadas e coletadas.

    Lara B Aknin

    Full Text Available Previous research has shown that spending money on others (prosocial spending increases happiness. But, do the happiness gains depend on who the money is spent on? Sociologists have distinguished between strong ties with close friends and family and weak ties--relationships characterized by less frequent contact, lower emotional intensity, and limited intimacy. We randomly assigned participants to reflect on a time when they spent money on either a strong social tie or a weak social tie. Participants reported higher levels of positive affect after recalling a time they spent on a strong tie versus a weak tie. The level of intimacy in the relationship was more important than the type of relationship; there was no significant difference in positive affect after recalling spending money on a family member instead of a friend. These results add to the growing literature examining the factors that moderate the link between prosocial behaviour and happiness.

  20. Taxing Feedlots in Alberta: Lethbridge County's Tax on Confined Feeding Operations

    Directory of Open Access Journals (Sweden)

    Bev Dahlby

    2017-11-01

    Full Text Available Lethbridge County introduced a new business tax on confined feeding operations (CFO, notably feedlots, in 2016. It was expected to bring in $2.5 million for county road maintenance in 2017. However, the tax could have a detrimental impact on feedlot owners and is not the fairest way to amass revenue for road repairs. Four criteria can be used to evaluate a particular form of taxation. They are fairness, efficient resource allocation, compliance and administration costs, and revenue stability. This paper examines the potential impacts of the tax and proposes three alternative methods for financing Lethbridge County road maintenance that meet those criteria. These alternatives create less of an impact on feedlot owners and share the tax burden more equitably. They also reduce the potentially negative ripple effects that the CFO levy may have on feed producers, cattle producers, meat packers and consumers. The current tax is based on livestock storage capacity, rather than on production volume. It’s counter-productive in the long run because the feedlot’s fixed costs of production are increased, while its variable costs remain unaffected. This permanent increase in fixed costs, estimated to be as high as 20 per cent of the average operating margin per head of cattle, lowers the return on feedlot investments. Thus, the new tax could result in some feedlots being closed for lack of a high enough return on investment.A more equitable revenue source for road maintenance would be user fees imposed on the trucking industry. This system is already in use in Oregon and New Zealand. It uses GPS technology to track trucks on the roads and then charges the trucking companies a fee based on road use. It would certainly be worthwhile for the province to initiate a pilot program to test the system’s efficacy on Alberta roads. Lethbridge County could also implement a usage levy that would be based on how much it spends on roads, combined with a feedlot

    We have used GPS-based local-tie measurements simultaneously with geo-VLBI observations since 2008 during every geodetic VLBI session at Metsähovi. This system uses gimbal-mounted GNSS antennas that are mounted on the reflector of the Metsähovi 14-m radio telescope. A similar system was installed in 2013 at the Onsala 20-m radio telescope and has been used for a large number of VLBI sessions, including, e.g., the 15-day-long CONT14 campaign. In order to verify the results of the two systems, we performed a dedicated measurement campaign in the framework of the SIB60 project, involving both Metsähovi and Onsala. During this campaign the local ties at the two stations were measured simultaneously during two VLBI sessions in August and September 2015 where both stations participated. The robot tacheometer monitoring system HEIMDALL was used for the automated classical monitoring of the telescopes at both stations. Moreover, additional local terrestrial measurements were performed several times to derive the full IVS-IGS local ties at both sites. The kinematic GPS measurements at the two stations were analyzed with two independently developed analysis programs. We present here the preparations of the campaign, the measurement process, and preliminary results.

  3. The emergence of cooperation in tie strength models

    International Nuclear Information System (INIS)

    Xu, Bo; Yue, Yunpeng

    2016-01-01

    In this paper, we propose a tie strength model to explain the emergence of cooperation in spatial prisoner's dilemma games, assuming that cooperators preferentially allocate their investments to friends with strong ties. Two types of prisoner's dilemma models are examined in this study: the traditional two-strategy model considering only cooperators and defectors; the expanded three-strategy model consisting cooperators, defectors and extortioners. The results show that tie strength model contributes to the promotion of cooperation in both types of prisoner's dilemma games. However, we point out that the influence of the investment preference is quite different in the two prisoner's dilemma game settings. In the two-strategy prisoner's dilemma game, only small preference contributes to the promotion of cooperation. Once this preference exceeds a critical value, cooperation will be prohibited. We explain this phenomenon by arguing that extremely strong investment preference undermines the ability of cooperative clusters to resist defectors. Moreover, we extend the analysis into the three-strategy case and discover that the catalytic effect of extortioners can eliminate this first up and then down trend in the two-strategy model. The equilibrium fraction of cooperators is always positively correlated to the level of investment preference in three-strategy models.

  4. Student Mobility and Transnational Social Ties as Factors of Reflexivity

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available The article seeks to develop and apply new quantitative measurement instruments capable of significantly improving understanding of the relationship between the transnational mobility and transnational social ties of students, along with their reflexive capacities. With a focus on students building their personal networks, educational and professional activities that extend beyond the nation’s borders and organising their day-to-day routines in transnational social spaces, we analyse the role of mobility in their reflexive capacities. Applying a tool that is line with Archer’s theory and indicators to measure reflexivity, and transnational social ties as proposed by Molina et al., we analyse data collected via an on-line survey questionnaire administered to Slovenian students. In addition, students from the Middle East (Lebanon and the USA (Hawai’i are added for comparative purposes. The results of path analysis show the Slovenian students’ mobility as such implies higher scores for meta reflexivity, combined with lower scores for communicative and fractured reflexivity. Further, social transactions reaching beyond one’s physical localities in terms of transnational social ties implies they have higher levels of reflexivity in general.

    The need of ERT method in nickel latentes exploration can’t be deny. This method have capability to make exploration more effective and efficient. In reality this method still remain ambiguity in its application, especially for geologist and mining expert. These ambiguity related with layer zone determination (limonite, saprolite and bedrock), the same resistivity values in the different zones and determination of bedrock. This paper try to expose interesting fact to overcome this ambiguity by using ERT data and drill data tie. This tie will show characteristic of nickel lateric based on resisitivity value and the contribution of chemistry element for resistivity value. Data ERT was collected by using gradient configuration and well data consist of mayor element and minor element. Tie result showed difference resistivity value in limonite layer influence by Fe, H2O and Ni, where resistivity value from saprolite layer influenced by Fe, H2O, Si02, MgO, Al, Cr, and Ni in certain accumulation. In bedrock layer, almost all drill data did not reach bedrock but only reached the boulder alone, it is supported by the value of the resistivity of rock unserpentinized peridotite which should show a relatively large resistivity value

    As one of the most popular vegetation indices to monitor terrestrial vegetation productivity, Normalized Difference Vegetation Index (NDVI) has been widely used to study the plant growth and vegetation productivity around the world, especially the dynamic response of vegetation to climate change in terms of precipitation and temperature. Alberta is the most important agricultural and forestry province and with the best climatic observation systems in Canada. However, few studies pertaining to climate change and vegetation productivity are found. The objectives of this paper therefore were to better understand impacts of climate change on vegetation productivity in Alberta using the NDVI and provide reference for policy makers and stakeholders. We investigated the following: (1) the variations of Alberta's smoothed NDVI (sNDVI, eliminated noise compared to NDVI) and two climatic variables (precipitation and temperature) using non-parametric Mann-Kendall monotonic test and Thiel-Sen's slope; (2) the relationships between sNDVI and climatic variables, and the potential predictability of sNDVI using climatic variables as predictors based on two predicted models; and (3) the use of a linear regression model and an artificial neural network calibrated by the genetic algorithm (ANN-GA) to estimate Alberta's sNDVI using precipitation and temperature as predictors. The results showed that (1) the monthly sNDVI has increased during the past 30 years and a lengthened growing season was detected; (2) vegetation productivity in northern Alberta was mainly temperature driven and the vegetation in southern Alberta was predominantly precipitation driven for the period of 1982-2011; and (3) better performances of the sNDVI-climate relationships were obtained by nonlinear model (ANN-GA) than using linear (regression) model. Similar results detected in both monthly and summer sNDVI prediction using climatic variables as predictors revealed the applicability of two models for

    This paper compares the markets for nuclear power in Alberta and Saskatchewan. This is done by comparing the two provincial panels that were released in Spring 2009 (Saskatchewan's Uranium Development Partnership and Alberta's Nuclear Power Expert Panel). Each panels terms of reference, membership, process, analysis, recommendations, and public consultation process are examined. Other variables for comparison include the history of its involvement in the nuclear sector, the political support, and public support. It concludes by arguing that Saskatchewan is a better market for nuclear power and that it is likely that a nuclear reactor will be built in Saskatchewan, but that surplus electricity will also be exported to Alberta. The possibility of building new nuclear power plants in both Alberta and Saskatchewan is increasing.

    This paper compares the markets for nuclear power in Alberta and Saskatchewan. This is done by comparing the two provincial panels that were released in Spring 2009 (Saskatchewan's Uranium Development Partnership and Alberta's Nuclear Power Expert Panel). Each panels terms of reference, membership, process, analysis, recommendations, and public consultation process are examined. Other variables for comparison include the history of its involvement in the nuclear sector, the political support, and public support. It concludes by arguing that Saskatchewan is a better market for nuclear power and that it is likely that a nuclear reactor will be built in Saskatchewan, but that surplus electricity will also be exported to Alberta. The possibility of building new nuclear power plants in both Alberta and Saskatchewan is increasing. This would not only increase the size of the Canadian nuclear industry it would also geographically expand it. Many non-Westerners see the prairies as a homogenous whole, but there are critical differences between Alberta and Saskatchewan. Analyzing these political and market differences would provide a good predicative power over the ultimate success of the nuclear power initiatives.

    Full Text Available Abstract Background Arnica montana L. and Artemisia absinthium L. (Asteraceae are medicinal plants native to temperate regions of Europe, including Romania, traditionally used for treatment of skin wounds, bruises and contusions. In the present study, A. montana and A. absinthium ethanolic extracts were evaluated for their chemical composition, antioxidant activity and protective effect against H2O2-induced oxidative stress in a mouse fibroblast-like NCTC cell line. Results A. absinthium extract showed a higher antioxidant capacity than A. montana extract as Trolox equivalent antioxidant capacity, Oxygen radical absorbance capacity and 2,2-diphenyl-1-picrylhydrazyl free radical-scavenging activity, in correlation with its flavonoids and phenolic acids content. Both plant extracts had significant effects on the growth of NCTC cells in the range of 10–100 mg/L A. montana and 10–500 mg/L A. absinthium. They also protected fibroblast cells against hydrogen peroxide-induced oxidative damage, at the same doses. The best protection was observed in cell pre-treatment with 10 mg/L A. montana and 10–300 mg/L A. absinthium, respectively, as determined by Neutral red and lactate dehydrogenase assays. In addition, cell pre-treatment with plant extracts, at these concentrations, prevented morphological changes induced by hydrogen peroxide. Flow-cytometry analysis showed that pre-treatment with A. montana and A. absinthium extracts restored the proportion of cells in each phase of the cell cycle. Conclusions A. montana and A. absinthium extracts, rich in flavonoids and phenolic acids, showed a good antioxidant activity and cytoprotective effect against oxidative damage in fibroblast-like cells. These results provide scientific support for the traditional use of A. montana and A. absinthium in treatment of skin disorders.

    An Alberta woman recently won a lawsuit against the government of Alberta for wrongful sterilization that took place when she was a 14-year-old ward at the Provincial Training School for Mental Defectives. It was the first time the province has been held accountable for actions taken under the Sexual Sterilization Act, a 1927 law that promoted the theory of eugenics and led to the sterilization of more than 2800 people. It has since been repealed. A physician who served on the province's Euge...

  15. Model-generated air quality statistics for application in vegetation response models in Alberta

    McVehil, G.E.; Nosal, M.

    1990-01-01

    To test and apply vegetation response models in Alberta, air pollution statistics representative of various parts of the Province are required. At this time, air quality monitoring data of the requisite accuracy and time resolution are not available for most parts of Alberta. Therefore, there exists a need to develop appropriate air quality statistics. The objectives of the work reported here were to determine the applicability of model generated air quality statistics and to develop by modelling, realistic and representative time series of hourly SO 2 concentrations that could be used to generate the statistics demanded by vegetation response models

  16. Deregulation and natural gas trade relationships: lessons from the Alberta-California experience

    International Nuclear Information System (INIS)

    Wilson, Patrick Impero

    1997-01-01

    In 1978 the US government moved to deregulate the American natural gas industry. The market changes that resulted from this initial step took time to ripple their way out to regional and subnational gas trading relationships. This ripple effect required subnational governments (state and provincial regulators) to rethink their gas regulatory policies. This article examines the restructuring of the Alberta-California gas trade. It explores how changes in US policy forced California and Alberta regulators to recast their policies. It concludes with several lessons that can be drawn from this case about the complex challenge of restructuring international gas trading relationships. (author)

    The different disposal options for drilling wastes as outlined in Guide 50 of the Alberta Energy and Utilities Board (EUB) are discussed. Guide 50 provides for the cost effective and environmentally sound disposal of drilling waste generated in Alberta. Each disposal option of the guide is reviewed and common methods of operation are outlined. Relative costs, environmental suitability and liability issues associated with each option are described. Issues regarding overall disposal considerations, on-site and off-site disposal options, hydrocarbon contamination, salt contaminated waste, toxic waste, and documentation of waste disposal outlined. Some recent programs which have been in the trial phase for a few years are also addressed

  18. The impact of offsets and REC's on the economics of wind projects in Alberta

    2011-07-01

    In Alberta, the electricity regime is de-regulated and there is no central power purchaser, as there is in other provinces. This system increases competition between energy providers and tends to lower the price to the consumer. Electric energy is exchanged through the Alberta power pool. Alberta also regulates greenhouse gas emissions. Emitters must reduce their emissions to a certain level or buy tech fund credits from the government or emission performance credits from providers who are within their emission limits. The specificity of the energy sector in Alberta provides both opportunities and challenges to the development of wind energy; the province has significant wind energy resources. The absence of a fixed price for power generated by wind energy requires creative financing approaches while emission offset credits can provide more value to wind power. This presentation showed that wind power energy in Alberta has a significant financial potential but that there are also significant risks.

  19. Threshold Considerations and Wetland Reclamation in Alberta's Mineable Oil Sands

    Directory of Open Access Journals (Sweden)

    Lee Foote

    2012-03-01

    Full Text Available Oil sand extraction in Alberta, Canada is a multibillion dollar industry operating over 143 km² of open pit mining and 4600 km² of other bitumen strata in northern boreal forests. Oil production contributes to Canada-wide GDP, creates socio-cultural problems, provides energy exports and employment, and carries environmental risks regarding long-term reclamation uncertainties. Of particular concern are the implications for wetlands and water supply management. Mining of oil sands is very attractive because proven reserves of known quality occur in an accessible, politically stable environment with existing infrastructure and an estimated 5.5 billion extractable barrels to be mined over the next five decades. Extraction occurs under a set of limiting factors or thresholds including: limited social tolerance at local to international levels for externalities of oil sand production; water demands > availability; limited natural gas supplies for oil processing leading to proposals for hydroelectric dams and nuclear reactors to be constructed; difficulties in reclaiming sufficient habitat area to replace those lost. Replacement of the 85 km² of peat-forming wetlands forecast to be destroyed appears unlikely. Over 840 billion liters of toxic fluid byproducts are currently held in 170 km² of open reservoirs without any known process to purify this water in meaningful time frames even as some of it leaches into adjacent lands and rivers. Costs for wetland reclamation are high with estimates of $4 to $13 billion, or about 6% of the net profits generated from mining those sites. This raises a social equity question of how much reclamation is appropriate. Time frames for economic, political, and ecological actions are not well aligned. Local people on or near mine sites have had to change their area use for decades and have been affected by industrial development. Examining mining effects to estimate thresholds of biophysical realities, time scales

    The context of healthcare organizations such as hospitals is increasingly accepted as having the potential to influence the use of new knowledge. However, the mechanisms by which the organizational context influences evidence-based practices are not well understood. Current measures of organizational context lack a theory-informed approach, lack construct clarity and generally have modest psychometric properties. This paper presents the development and initial psychometric validation of the Alberta Context Tool (ACT), an eight dimension measure of organizational context for healthcare settings. Three principles guided the development of the ACT: substantive theory, brevity, and modifiability. The Promoting Action on Research Implementation in Health Services (PARiHS) framework and related literature were used to guide selection of items in the ACT. The ACT was required to be brief enough to be tolerated in busy and resource stretched work settings and to assess concepts of organizational context that were potentially modifiable. The English version of the ACT was completed by 764 nurses (752 valid responses) working in seven Canadian pediatric care hospitals as part of its initial validation. Cronbach's alpha, exploratory factor analysis, analysis of variance, and tests of association were used to assess instrument reliability and validity. Factor analysis indicated a 13-factor solution (accounting for 59.26% of the variance in 'organizational context'). The composition of the factors was similar to those originally conceptualized. Cronbach's alpha for the 13 factors ranged from .54 to .91 with 4 factors performing below the commonly accepted alpha cut off of .70. Bivariate associations between instrumental research utilization levels (which the ACT was developed to predict) and the ACT's 13 factors were statistically significant at the 5% level for 12 of the 13 factors. Each factor also showed a trend of increasing mean score ranging from the lowest level to the

    2012-12-01

    In recent years, improved exploration techniques have resulted in the serendipitous discoveries of increasing numbers of extraterrestrial impact structures in sedimentary basins around the world. Following in this tradition, a new potential impact structure centered near 50.4°N, 112.35°N in SE Alberta has been identified. The first indications of this structure appeared in careful systematic mapping of Cretaceous age sediments using public domain well log information that showed overturned and missing components in what regionally is a simple layered stratigraphy. This motivated the examination of legacy 2D seismic profiles over the area that confirmed the stratigraphic anomalies and provided new details that further supported interpretation of a potential impact structure. Further, the existence of unexpected faults through the Cretaceous Bearpaw formation had been noted as early as the 1940's in the limited outcrop available in coulees, and these as well as other complex fault structures along the Bow River outcrops were confirmed in recent field visits to the site. The 2D seismic data displays a number of listric and rose-petal faulting consistent with late stage collapse of the impact crater. Further, a seismically transparent central uplift peak is visible. Based on the results, the structure is recognized as a complex crater with a diameter of approximately 8 kilometers and, today, bottoming at a depth of 900 meters from the current surface. Currently, the age of the feature is grossly estimated to be less than 70 my on the basis of underlying undisturbed seismic reflectors. The structure may be somewhat unique in that weak coals surrounding the feature are clearly thickened indicating outward lateral sliding along shear planes through weaker layers. Work in progress includes acquisition of a high resolution seismic profile and detailed mapping of the magnetic and gravity potential fields. More detailed mapping will include searches for shock metamorphism

    Significant environmental issues and regulatory proceedings in Alberta were discussed. The Mackenzie Valley Pipeline Project was reviewed in relation to the Deh Cho First Nation's advanced actions in the federal court to enjoin the review panel from proceeding with the review process. The Deh Cho First Nation is seeking a declaration that the plan violates their rights under the Canadian Charter of Rights and Freedoms and the Constitution Act. Various regulatory and government agencies have now developed a plan to coordinate their different regulatory processes and approvals in the Cooperation Plan for the Environmental Impact Assessment and Regulatory Review of the Northern Gas Pipeline project. The Deh Cho allege that they were not afforded the opportunity to participate in the development and implementation of the plan. A review panel plans to proceed once the environmental and social impacts are determined, and the consortiums plan to minimize harm has been submitted. Issues concerning contaminated sites were discussed with reference to Lynnview Ridge, where Imperial Oil and Devon Estates Ltd. built a residential subdivision built on the site of a decommissioned oil storage tank site. Periodic monitoring detected some general concerns, including high lead levels in soil and hydrocarbon vapors. Environmental Protection Orders (EPO) and appeals were discussed, including Imperial and Devon's appeal that the pollution problem should have been addressed through the contaminated sites provision and not the substance release EPO. Several recommendations were made, including better definition processes for liability allocation; a clarification of persons excluded from responsibility; voluntary remediation agreements that limit liability; and environmental site information systems to support due diligence. It was expected that the final set of recommendations will be of use to all jurisdictions in Canada. Regulatory issues concerning public safety were

    Assessment of glacial melt is critical for water resource management in areas which rely on glacier-fed rivers for agricultural and municipal uses. Changes in precipitation patterns coupled with current glacial retreat are altering the glacial contribution to river flow in areas such as the Andes of South America and the high ranges of Asia, as well as the Rockies of Western Canada. Alberta’s Bow River has its headwaters in the eastern slopes of the Canadian Rockies and contributes to the Nelson drainage system feeding into Hudson Bay. The Bow River basin contains several population centers, including the City of Calgary, and is heavily taxed for agricultural use. The combined effects of rapid glacial retreat in the Canadian Rockies, higher drought frequency, and increased demand are likely to heighten water stress in Southern Alberta. However, there has been little focus to date on the extent and importance of glacial meltwater in the Bow River. The Bow River contains 74.5 km2 of glacier ice, which amounts to only 0.29% of the basin. While this number is not high compared to some glacierized areas, Hopkinson and Young (1998) report that in dry years, glacier melt can provide up to 50% of late summer flows at a station in the upper reaches of the river system. We extend this work with an assessment of monthly and annual glacial contributions to the Bow River farther downstream in Calgary. Our analysis is based on mass balance, meteorological, and hydrological data that has been collected at the Haig Glacier since 2001. This data is used in conjunction with glacier coverage and hypsometric data for the remainder of the basin to estimate seasonal snow and glacial meltwater contributions to the Bow River from the glacierized fraction of the catchment. The results of this study show the percentage of total flow attributed to glacial melt to be highly variable. Glacier runoff contributes up to an order of magnitude more water to the Bow River per unit area of

    A mineral survey conducted within the Centennial Mountains Wilderness study area in Montana and Idaho showed large areas of probable and substantiated resource potential for phosphate. Byproducts that may be derived from processing the phosphate include vanadium, chromium, uranium, silver, fluorine, and the rare earths, lanthanum and yttrium. Results of a geochemical sampling program suggest that there is little promise for the occurrence of base and precious metals in the area. Although the area contains other nonmetallic deposits, such as coal, building stone, and pumiceous ash they are not considered as mineral resources. There is a probable resource potential for oil and gas and significant amounts may underlie the area around the Peet Creek and Odell Creek anticlines.

    2002-01-01

    The TIES method is a forecasting environment whereby the decision-maker has the ability to easily assess and trade-off the impact of various technologies without sophisticated and time-consuming mathematical formulations. TIES provides a methodical approach where technically feasible alternatives can be identified with accuracy and speed to reduce design cycle time, and subsequently, life cycle costs, and was achieved through the use of various probabilistic methods, such as Response Surface Methodology and Monte Carlo Simulations. Furthermore, structured and systematic techniques are utilized from other fields to identify possible concepts and evaluation criteria by which comparisons can be made. This objective is achieved by employing the use of Morphological Matrices and Multi-Attribute Decision Making techniques. Through the execution of each step, a family of design alternatives for a given set of customer requirements can be identified and assessed subjectively or objectively. This methodology allows for more information (knowledge) to be brought into the earlier phases of the design process and will have direct implications on the affordability of the system. The increased knowledge allows for optimum allocation of company resources and quantitative justification for program decisions. Finally, the TIES method provided novel results and quantitative justification to facilitate decision making in the early stages of design so as to produce affordable and quality products.

  12. Topic Detection Based on Weak Tie Analysis: A Case Study of LIS Research

    Directory of Open Access Journals (Sweden)

    Ling Wei

    2016-11-01

    Full Text Available Purpose: Based on the weak tie theory, this paper proposes a series of connection indicators of weak tie subnets and weak tie nodes to detect research topics, recognize their connections, and understand their evolution. Design/methodology/approach: First, keywords are extracted from article titles and preprocessed. Second, high-frequency keywords are selected to generate weak tie co-occurrence networks. By removing the internal lines of clustered sub-topic networks, we focus on the analysis of weak tie subnets' composition and functions and the weak tie nodes' roles. Findings: The research topics' clusters and themes changed yearly; the subnets clustered with technique-related and methodology-related topics have been the core, important subnets for years; while close subnets are highly independent, research topics are generally concentrated and most topics are application-related; the roles and functions of nodes and weak ties are diversified. Research limitations: The parameter values are somewhat inconsistent; the weak tie subnets and nodes are classified based on empirical observations, and the conclusions are not verified or compared to other methods. Practical implications: The research is valuable for detecting important research topics as well as their roles, interrelations, and evolution trends. Originality/value: To contribute to the strength of weak tie theory, the research translates weak and strong ties concepts to co-occurrence strength, and analyzes weak ties' functions. Also, the research proposes a quantitative method to classify and measure the topics' clusters and nodes.

  14. Initial scoping of GHG emissions trading potential in Alberta : CABREE discussion paper

    International Nuclear Information System (INIS)

    Armstrong, R.

    2002-03-01

    The past five years have seen the emergence of the concept of emissions trading for greenhouse gases, which would make possible a reduction of the costs required to meet emissions targets agreed upon under the Kyoto Protocol. Emissions trading potential and initial scoping in Alberta is examined in this document, with a special emphasis placed on greenhouse gases. The design of a system, encompassing the theory underlying the mechanism, the current developments, issues of importance in this context, as well as the potential for inclusion of other sectors in Alberta were also discussed. For the purpose of this document, emissions trading was defined as one party reducing its emissions levels then transferring the ownership of that reduction to another party who can then purchase this reduction to assist in meeting its own emissions target. Emission trading can be divided into two basic types called Cap and Trade, and Baseline and Credit. Market creation and behaviour, and regulatory behaviour are factors that can render a trading system more feasible. It is important to analyze the goals before designing the specifics of the system. The incorporation of the various sectors of the economy of Alberta would be affected by their unique features. The greatest promise for emissions trading in Alberta is shown by the energy sector. The percentage of emissions covered, the number of participants, the economic effectiveness are all criteria that affect the performance of any system. figs

    The sulphur recovery of Alberta's grandfathered sour gas plants is monitored by the Alberta Energy and Utilities Board. This report provides an annual summary of industry performance for sulphur recovery at large acid gas flaring sour gas plants, and sulphur recovery at all acid gas injection sour gas plants. It follows Interim Directive (ID) 2001-3 which stipulates guidelines for sulphur recovery for the province of Alberta. It includes a list of grandfathered and non grandfathered plants in Alberta. Grandfathered sulphur recovery plants that exceed expectations have the option to file a sulphur emission performance credit report and can use the credits to meet some of their sulphur requirement in the future. Acid gas flaring plants face more stringent requirements and cannot earn credits. Several plants have degrandfathered in the past 5 years. Eleven have made upgrades, 4 have been relicensed to meet the requirements for new plants, and 4 have shut down. Forty-one grandfathered plants remain.

    The Alberta Energy and Utilities Board is mandated by the Government of Alberta to ensure fair, responsible development and delivery of energy resources and utilities services in Alberta while maintaining the best public interest. One of the agencies' priorities is the reduction of solution gas flaring and venting. The performance of solution gas flaring and venting in Alberta and best practices respecting solution gas conservation are discussed. Data was presented on solution gas production, solution gas conserved, and solution gas conservation efficiency. The paper described best practices solutions such as increased gas to oil (GOR) test frequency; predetermination of economic gas conservation; collaboration with county gas utilities; and utilization of portable and scalable gas compression. The paper also presents a discussion of the Clean Air Strategic Alliance (CASA), a non-profit multistakeholder that recommended enhancements to Guide 60. Requirements discussed include the requirement to conserve solution gas at certain sites exceeding established flare and vent volumes, gas conservation prebuild requirements, and enhanced economic evaluation process. 5 figs.

  18. Generic market design issues highlighted: prices soar in Alberta as capacity tightens

    Many Alberta consumers, alarmed by enormous price increases, are asking questions about whether electric sector restructuring in the province has progressed far enough. The average cost of power in Alberta's spot market in October were $70.46 per MWH above the $20-$30 that consumers had paid in recent years. It is widely admitted that the high prices reflect an increasingly tight supply situation in which construction of new capacity has not kept pace with growth in demand. It is a standard case of what happens when the market design focuses on promoting short-term price competition to the detriment of creating compeition in the forward markets. A debate has been produced in Alberta with major power consumers calling for a breakup of the three major generators, and the government suggesting that such intervention would be like returning to the days before competition when government tried to control everything. Competition may not work unless divestiture is revisited. There is a hard time seeing the light at the end of the restructuring tunnel for industrial consumers. Ontario's Market Design Committee struggled with the same issue, believing that an industry composed of many smaller independent generating companies was the only way to achieve lasting and meaningful price competition. The best price protection for consumers is an active and competitive investment market for new capacity, and Alberta should not repeat Ontario's mistake and leave the work until price problems develop

    The frustrations of environmental groups were expressed by a representative from the Canadian Parks and Wilderness Society. Emphasis was placed on the lack of support from the Alberta government to protect lands from industrial development. Some recent major conflict between the oil industry, the Alberta government, and environmentalists were chronicled. As an example, the government's Special Places 2000 program, which designates environmentally-sensitive areas in Alberta, was boycotted by environmental groups, because in the view of environmental groups, the policy failed to clearly designate protected areas. In 1993, environmental groups approached major oil and gas companies to establish an agreement on which lands were to be protected. As a result, the Eastern Slopes Environment and Energy Committee (ESEE) was formed, however, the Alberta government failed to support this initiative. The speaker recommended a greater degree of public involvement in decisions regarding access to lands for industrial development.More rigorous assessments at proposed development sites prior to industrial activity was also suggested. In the view of the speaker further conflict between environmental groups and the energy industry were inevitable, unless the industry took some responsibility in protecting environmentally-sensitive lands

    This document commented on the release of Alberta's 2007 Royalty Review Panel regarding the province's royalty system for petroleum and oil sands development. It argued that the report does not fulfill the spirit of Alberta's royalty system, which is to expect nothing less than 100 per cent of the rent collection. This document provided an analysis of the set of recommendations made by the panel. It began with a general discussion of the problems in which the royalties review was structured and flaws in the base assumptions made by the panel. It also provided an analysis of the specific recommendations within the panel's report. Last, the report proposed a set of recommendations on how a royalties reform should proceed. The authors found specific recommendations Alberta's 2007 Royalty Review Panel report to be problematic. These included the 1 per cent royalty holiday on tar sands oil; higher net royalty rate; windfall profits tax; coal bed methane and cuts in royalties for low producing wells; and value added incentives. It was concluded that the panel's report was a compromise between the public interest and those of the oil and gas sector and that the panel's goal of ensuring that Alberta remained one of the lowest tax and royalty jurisdictions in the world was fundamentally flawed. 32 refs., 4 figs

  2. Forecast of common air contaminants in Alberta (1995 to 2020) : Final report

    International Nuclear Information System (INIS)

    2002-04-01

    In this document, a distinction is made between anthropogenic sources (industrial, residential, commercial, institutional, transportation, and area sources) and natural sources (forest fires and biogenic sources). Nitrogen oxides, sulphur oxides and carbon monoxide are caused by both sources, but their ratio varies. The emphasis of this report was on the growth in anthropogenic emissions in Alberta from industrial sources. For the purpose of this forecast, the natural sources were kept constant at 1995 levels. An inventory of common air contaminants (CAC) in Alberta was obtained in 1995 and formed the starting point of this forecast. Under business as usual scenario, CAC emissions in Alberta are expected to increase. The increase is expected to be in the 18 per cent range by 2010 and 32 per cent range by 2020 over the levels of 1995. Anticipated energy efficiency improvements, as well as a shift toward less CAC-intensive fuels like natural gas explain this slower growth. In the context of improved vehicle emission standards, reduced emissions from transportation were anticipated. There are wide differences for the magnitude of the projected change for each of the CACs. The greatest increase was forecasted for total particulate emissions caused in large part by road dust. A decrease was forecasted for sulphur oxides and carbon monoxide emissions as a result of improved fuel and vehicle emission standards. For each of Alberta's 19 census divisions or regions, estimates of forecasted 2010 emissions from each source category were included. 24 refs., 77 tabs

    An advanced technical screening program was used to successfully screen and rank a very large number of Alberta oil pools for enhanced oil recovery using carbon dioxide (CO{sub 2}) flooding. This paper is a continuation paper describing the results of using the Microsoft Excel program with VBA to estimate production forecasts for several candidate pools in Alberta. A total of 6 ranking parameters were used, including API gravity of oil, residual oil saturation, ratio between reservoir pressure and minimum miscibility pressure, reservoir temperature, net pay thickness and porosity. The screening program provides a technical ranking of approximately 8,000 Alberta pools. After compilation of the Alberta oil pools, it was determined that most of the deep carbonate oil pools are excellent candidates for CO{sub 2} miscible flooding. Other Devonian carbonate pools are also ranked as having high potential for the process. An environmental benefit of CO{sub 2} miscible flooding process is that carbon sequestration has the potential to reduce anthropogenic carbon dioxide emissions from reaching the atmosphere. Ongoing studies are currently addressing CO{sub 2} capture and transportation, making EOR technology viable for maintaining light oil production in western Canada. 11 refs., 2 tabs., 2 figs.

  8. Management of industrial sulfur dioxide and nitrogen oxides emissions in Alberta - description of the existing system

    Macdonald, W.S.; Bietz, B.F.

    1999-01-01

    In addition to being key primary air contaminants, sulfur dioxide and nitrogen oxides are also major contributors to acidic deposition. The current management system for controlling industrial sources of SO(2) and NO(x) emissions in Alberta was developed in the late 1960s/early 1970s. The focus is on control of point source emissions through the use of appropriate technology. The approach taken for managing SO(2) and NO(x) emissions is similar to the approach taken to other industrial air and wastewater pollutants in Alberta. It is a command and control regulatory system. There are three main industry categories in Alberta which emit SO(2): sour gas processing, oil sand plants and thermal power plants. For NO(x) emissions, the two main categories with emissions: are natural gas production and thermal power plants. The two main goals of the existing industrial air quality management systems are to ensire that: (1) emissions from industrial facilities are minimized through the use of best available demonstrated technology, and (2) ambient levels of air contaminants in the vicinity of industrial facilities do not exceed Alberta guidelines. The four main policies which support these two goals of the existing management system are described. There are a number of key components of the existing management system including: ambient guideline levels, source emission standards, plume dispersion modelling, ambient air and source emission monitoring, environmental reporting, emission inventories, and approvals. 32 refs., 13 figs

    Full Text Available Growing interest among academics and health professionals in finding new ways to study and address complex health and social problems has manifested in recent years with increasing community demands for research and program implementation that is community-based, rather than merely community placed. In the United States, community-based participatory research (CBPR, with its emphasis on the creation and use of community-university or community-academic partnerships, is the prevailing paradigm to address these complex problems, especially those concerning racial/ethnic disparities in health and health care. While the need to strengthen the relationship between researchers and the community has been recognised, often from the viewpoint of the university partner, discussions on sustainability of partnerships have been few. The aim of this paper is to share reflections, through the eyes of the community members, on the core elements that tie community and academic members together and the challenges in understanding and nurturing those ties so that the community-academic partnership is sustained over time, and to offer possible recommendations for sustainability. This article speaks from the community’s perspective and reflects on the vital elements/components that tie together community-university partnerships and the challenges that may occur when trying to sustain and grow the partnership. It is based on a research CBPR study that was conducted to (1 evaluate the functioning and future sustainability of the community-university partnership of the Community Child Health Network Study Los Angeles (CCHN-LA community-university partnership, and (2 evaluate the experience and beliefs of the current CCHN-LA community-university partnership members in their understanding of current functioning.

    Full Text Available The aim of this review is to create a complete analysis about tongue-tie (or short lingual frenum or ankyloglossia according to the most important works published in literature. The analysis allowed us to do a complete evaluation of this problem, from embriology to the therapeutic approach we could use today, focusing our attention on laser-assisted therapy. This review is based on the research on the PubMed Database (www.ncbi.nlm.nih.gov of studies about lingual frenum written in English between January 1980 and May 2014. The keywords inserted were “lingual frenum”, “frenectomy”, “laser therapy”. We have analyzed: case series, case reports, clinical studies, and also literature reviews in which embryology, physiology, diagnosis and treatment of ankyloglossia were described. We excluded laboratory studies, studies based on animal tests and studies about patients with particular syndromes in which we can also find tongue-tie. The selection criteria allowed us to select 42 articles. The treatment options for the releasing of the frenum are surgically represented by frenotomy (i.e. simple horizontal cut of this training and frenectomy (i.e. removal. In both cases, the intervention on the short lingual frenum is simple, short-lasting, and without particular complications. Furthermore, this kind of treatment can be carried out with different devices: with the typical cold blade scalpel or by the use of laser, a new method that shows more advantages over the prior art. Laser-assisted therapy permits to intervene on newborns (from 0 to 20 days, when there are breastfeeding problems without total anesthesia and suture. The Er:YAG, CO2 laser (according to literature data and Diode laser (according to our experience are advantageous, safe and effective in tongue-tie treatment.

  18. A Cooperative Industry - Government Woodland Caribou Research Program in Northeastern Alberta

    Directory of Open Access Journals (Sweden)

    Blair Rippin

    1996-01-01

    Full Text Available Rapid development of large scale logging and increasingly intensive petroleum exploration and development in northeastern Alberta prompted the establishment of a cooperative research program to investigate various aspects of woodland caribou (Rangifer tarandus caribou biology. The ultimate goal of the program is to develop an effective plan that will ensure the long term survival of caribou while allowing for renewable and non-renewable resource development. There are three parts to the program. Part I began early in 1991 and makes use of conventional radio telemetry as a means of recording various parameters of general caribou biology. The study area encompasses approximately 4000 km2 of low relief, boreal mixedwood forest. Preliminary results from 2500 radio locations (involving 50 individuals indicate that woodland caribou inhabiting the study area are non-migratory and are strongly associated with some of the more scarce peatland forest types present in the area. Investigations to document the basic biology and ecology will continue for another two years. Part II began in early 1993 as a part of a two-year investigation into the disturbance effects of petroleum exploration and development on caribou movements and behaviour. One objective of this study is to develop a predictive model useful in determining the cumulative effects of varying intensities of disturbance on caribou. Part III began in early 1994 with a proposed three-year investigation to determine the mechanism of spatial and temporal separation of caribou and moose in the study area. These relationships may indicate the means by which caribou minimize the impact of wolf predation on their populations in northeastern Alberta. Results will be applied to industrial land use and specifically to large scale forest harvesting planned for the area. The research program is supported through cooperative funding contributed by 24 petroleum companies, 1 forest company, 2 peat companies and

    2013-06-01

    Motivated by empirical evidence on the interplay between geography, population density and societal interaction, we propose a generative process for the evolution of social structure in cities. Our analytical and simulation results predict both super-linear scaling of social-tie density and information contagion as a function of the population. Here we demonstrate that our model provides a robust and accurate fit for the dependency of city characteristics with city-size, ranging from individual-level dyadic interactions (number of acquaintances, volume of communication) to population level variables (contagious disease rates, patenting activity, economic productivity and crime) without the need to appeal to heterogeneity, modularity, specialization or hierarchy.

    Full Text Available Cohabitation has been spreading in the population during the last thirty years, and this is one of the most striking aspects of wider social changes that have taken place throughout the industrialized world. However, this change did not take place uniformly across Europe. The purpose of this paper is to contribute to the current debate around the compatibility of cohabitation experiences with the Italian cultural context. Using an individual-level diffusion approach we obtain results that are consistent with the crucial role that family ties play in the choice of cohabitation in place of (or before marriage.
