    A blood survey for the prevalence of the microfilariae of the canine heartworm, Dirofilaria immitis was conducted in the Calgary area of southern Alberta between November 1977 and August 1979. A total of 514 blood samples was examined by the modified Knott's test. All of the samples were negative for D. immitis microfilariae. Wright's stained blood smears taken from 19 animals at the Calgary Zoo also proved negative. One smear from a male two-toed sloth (Choloepus didactylus) contained sheath...

    Full Text Available Background. Canadian policy requires refugees with a history of tuberculosis (TB or abnormal chest radiograph to be screened after arrival for TB. However, Tibetan refugees are indiscriminately screened, regardless of preimmigration assessment. We sought to determine the incidence of latent (LTBI and active TB, as well as treatment-related outcomes and associations between preimmigration factors and TB infection among Tibetan refugees arriving in Calgary, Alberta. Design. Retrospective cohort study including Tibetan refugees arriving between 2014 and 2016. Associations between preimmigration factors and incidence of latent and active TB were determined using Chi-square tests. Results. Out of 180 subjects, 49 percent had LTBI. LTBI was more common in migrants 30 years of age or older (P=0.009. Treatment initiation and completion rates were high at 90 percent and 76 percent, respectively. No associations between preimmigration factors and treatment completion were found. A case of active TB was detected and treated. Conclusion. Within this cohort, the case of active TB would have been detected through the usual postsurveillance process due to a history of TB and abnormal chest radiograph. Forty-nine percent had LTBI, compared to previously quoted rates of 97 percent. Tibetan refugees should be screened for TB in a similar manner to other refugees resettling in Canada.

    Green roofs have been used for centuries to insulate buildings and beautify urban environments. European countries, especially Germany, have adopted green roofs use in modern buildings, helping raise awareness of their many potential benefits. Green roofs have been shown to: effectively reduce and filter stormwater thereby decreasing the burden on urban sewer systems; provide insulation and lower roof surface temperature leading to a decrease in building energy load and reduced sensible heat flux to the urban atmosphere; and to extend the life of a roof by decreasing the temperature fluctuations which cause roof damage. Given that green buildings can mitigate against the negative impacts of storm water runoff and reduce the heating and cooling demands, use of green roofs in Canada might prove extremely beneficial due to our intense climate. However, the implementation of green roofs in North American urban environments remains underused, in part due to a lack of climate appropriate green roof design guidelines that are supported by scientific understanding of their performance in North American climates. The capacity of a green roof installation to moderate runoff depends on the storage capacity of the rooting medium at the start of the rainfall event which in turn is constrained by roof loading. The influence of medium depth is investigated through comparison to 15 cm and 10cm deep planting modules. Storage capacity has a finite limit, making rapid drainage and evapotranspiration loss essential to restore the retardation of a subsequent storm. Sustaining live plant cover requires avoidance of saturated conditions and retention of minimum soil moisture levels. These limits constrain the design options with distinctive climatic stresses. Here the performance of experimental green roof modules is investigated under particularly high climatic stressing at Calgary Alberta Canada. 10 cm modules show rapid drying to unacceptably low residual moisture content, whereas 15

    The Community Development Learning Initiative (CDLI) in Calgary, Alberta, Canada aims to be a network that brings together neighbourhood residents, community development practitioners and other supporters to learn and act on neighbourhood-based, citizen-led community development projects. In 2013, the CDLI initiated The Evaluation for Learning and Dialogue Project to provide the opportunity for organizations and supporters to work together to establish a shared vision and goals through discussions about evaluation learning and outcomes. It was intended that the project would be a useful learning tool for participating organizations by enabling them to engage in an evaluative methodological process, and record relevant information and to compare and learn from each other's projects. Outcome Harvesting was chosen as the evaluation methodology for the project. This article reviews critical learning from the project on the use of Outcome Harvesting methodology in the evaluation learning and outcomes of local community development projects, and it provides lessons for other jurisdictions interested in implementing this methodology.

  11. Calgary Laboratory Services

    Directory of Open Access Journals (Sweden)

    James R. Wright MD, PhD

    2015-12-01

    Full Text Available Calgary Laboratory Services provides global hospital and community laboratory services for Calgary and surrounding areas (population 1.4 million and global academic support for the University of Calgary Cumming School of Medicine. It developed rapidly after the Alberta Provincial Government implemented an austerity program to address rising health care costs and to address Alberta’s debt and deficit in 1994. Over roughly the next year, all hospital and community laboratory test funding within the province was put into a single budget, fee codes for fee-for-service test billing were closed, roughly 40% of the provincial laboratory budget was cut, and roughly 40% of the pathologists left the province of Alberta. In Calgary, in the face of these abrupt changes in the laboratory environment, private laboratories, publicly funded hospital laboratories and the medical school department precipitously and reluctantly merged in 1996. The origin of Calgary Laboratory Services was likened to an “unhappy shotgun marriage” by all parties. Although such a structure could save money by eliminating duplicated services and excess capacity and could provide excellent city-wide clinical service by increasing standardization, it was less clear whether it could provide strong academic support for a medical school. Over the past decade, iterations of the Calgary Laboratory Services model have been implemented or are being considered in other Canadian jurisdictions. This case study analyzes the evolution of Calgary Laboratory Services, provides a metric-based review of academic performance over time, and demonstrates that this model, essentially arising as an unplanned experiment, has merit within a Canadian health care context.

    Full Text Available Diagnostic laboratory services in Alberta have been dramatically restructured over the past five years. In 1994, Alberta Health embarked on an aggressive laboratory restructuring that cut back approximately 30% of the overall monies previously paid to the laboratory service sector in Calgary. A unique service delivery model consolidated all institutional and community-based diagnostic testing in a company called Calgary Laboratory Services (CLS in late 1996. CLS was formed by a public/private partnership between the Calgary Regional Health Care Authority (CRHA and MDS-Kasper Laboratories. By virtue of its customer service base and scope of testing, CLS provides comprehensive regional laboratory services to the entire populace. Regional microbiology services within CLS have been successfully consolidated over the past three years into a centralized high volume laboratory (HVL. Because the HVL is not located in a hospital, rapid response laboratories (RRLs are operated at each acute care site. Although the initial principle behind the proposed test menus for the RRLs was that only procedures requiring a clinical turnaround time of more than 2 h stay on-site, many other principles had to be used to develop and implement an efficient and clinically relevant RRL model for microbiology. From these guiding principles, a detailed assessment of the needs of each institution and extensive networking with user groups, the functions of the microbiology RRLs were established and a detailed implementation plan drawn up. The experience at CLS with regards to restructuring a regional microbiology service is described herein. A post-hoc analysis provides the pros and cons of directing and operating a regionalized microbiology service.

    To evaluate the value of Calgary score and modified Calgary score in differential diagnosis between neurally mediated syncope and epilepsy in children. 201 children experienced one or more episodes of loss of consciousness and diagnosed as neurally mediated syncope or epilepsy were enrolled. Calgary score, modified Calgary score and receiver-operating characteristic curve were used to explore the predictive value in differential diagnosis. There were significant differences in median Calgary score between syncope [-4.00 (-6, 1)] and epilepsy [2 (-3, 5)] (z = -11.63, P epilepsy were 91.46 and 95.80 %, suggesting a diagnosis of epilepsy. There were significant differences in median modified Calgary score between syncope [-4.00 (-6, 1)] and epilepsy [3 (-3, 6)] (z = -11.71, P epilepsy. The sensitivity and specificity of modified Calgary score and Calgary score did not show significant differences (P > 0.05). Calgary score and modified Calgary score could be used to differential diagnosis between syncope and epilepsy in children.

    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. This includes accurate 3D renders of the exterior and interior spaces and a collection of architectural drawings comprising floor plans, sections, and elevations.

    Full Text Available During the early 1960s, largely as a result of the "baby boom" of the 1940s, large numbers of students of college age surfaced. They demanded a wider scope for higher education in Canada. The period saw not only the expansion of facilities in already established universities, but also the creation of many new institutions, among them the University of Calgary. During the early 1960s, the number of full-time professionals practicing and teaching anthropological archaeology in Canada could be counted on the fingers of two hands. The centre of gravity was the National Museum of Canada in Ottawa; of the three to four research archaeologists there, Dr. James V. Wright and Dr. George MacDonald offered occasional instruction at nearby universities. As for other universities, Dr. J. Norman Emerson held a full-time position at the University of Toronto, as did Dr. William J. Mayer-Oakes at the University of British Columbia. Mayer-Oakes was then able to devote part of his valuable time to archaeology while Dr. Richard G. Forbis of the Glenbow Foundation served as sessional lecturer at the University of Alberta, Calgary Branch.

    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.

    2012-01-01

    Community mental health nurses had a central role in the construction of new rehabilitative practices and community mental health services in the 1960s and 1970s. The purpose of this article is, first, to explore how nurses understood and created their new role and identity in the turbulent context of deinstitutionalization. The development of after care services for patients discharged from Alberta Hospital in Ponoka (AH-Ponoka), a large mental institution in Calgary, in the Canadian province of Alberta, will be used as a case study. I specifically focus on the establishment of outpatient services in a new psychiatric department at Foothills General Hospital in Calgary. Second, I examine how deinstitutionalization itself shaped community mental health nurses' work. Oral history interviews with nurses and other mental health professionals, who had a central role in this transformation process, provide a unique lens through which to explore this social change. The article concludes that new rehabilitative, community-based mental health services can better be understood as a transformation of former institutional practices rather than as a definite break with them.

    2013-08-01

    With the aim of optimizing diabetes education, type 2 diabetes awareness, primary prevention and secondary prevention, we studied how African Canadians experience type 2 diabetes. Specifically, we studied stories told by African Canadians living in Calgary, Alberta, Canada, about significant events and experiences at the time of their diagnosis with type 2 diabetes. From recorded interviews, we extracted themes from stories about diagnosis, using hermeneutic phenomenology. Participants included 11 African Canadians older than age 18 and at least 1-year post-diagnosis. Transcribed stories were analyzed for units of meaning describing significant themes/experiences about the diagnosis. Extracted units of meaning were organized into themes that were presented to a focus group of African Canadians in Calgary to garner their perspective on the findings, discuss the implications and make recommendations for improvements. All participants reported experiencing shock, disbelief, fear and a sense of helplessness immediately after their diagnosis. These rendered them unable to think clearly or start their treatment regimen until propelled by additional forces. Also, 73% of participants reported experiencing anger/denial about the diagnosis for some time, whereas 18% reported a short-lived relief that they could finally put a name to their symptoms. However, the overarching issue associated with all of the themes appeared to emanate from a lack of type 2 diabetes awareness. Emotions experienced by participants seemed precipitated by a lack of type 2 diabetes awareness. Some community-specific factors contributed to the lack of type 2 diabetes awareness, which appeared to impede primary and secondary prevention among participants. Recommendations for ameliorating these factors are presented. Copyright © 2013 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.

  12. Is Alberta`s gas running out?

    Energy Technology Data Exchange (ETDEWEB)

    Koch, G.

    1995-09-18

    The state of Alberta`s natural gas resources were reviewed and according to certain groups of experts reserves and resources were found to be less plentiful than generally believed. The Canadian Association of Petroleum Producers (CAPP) also reported that gas reserves in non-frontier areas declined by 1.8% lat year, to 67.4 trillion cubic feet. It was estimated that this supply would last for 13 years. The National Energy Board (NEB) indicated that thousands of Alberta`s unconnected pools may not be economical to develop. The CAPP annual reserves report also indicated that average gas pools found in recent times were only one quarter of the size of gas pools found before 1980. It was argued by this same group of experts that low gas prices, particularly for Alberta exports, have made drilling uneconomical, while others maintained that price fluctuations must be accepted as part of selling a commodity that is marketed world-wide. Ed Wolf, an independent geologist, estimated that gas prices,factoring in environmental costs, should be increased to $4 per mcf to justify exporting Canadian natural gas. However, others have argued that reserve figures have been underestimated. As proof of that they point to the fact that there is no shortage of investment capital; exploration and production activities, funded by investment, would not continue if natural gas production were not cost-effective. The Ziff Energy Group estimated that discovered and frontier reserves total 426 tcf, or 65 years` supply, excluding tight gas from low porosity formations which have been estimated to provide up to 300 years of supply at current levels of demand. As well, new technologies have improved the industry`s ability to find new reserves. The debate between economic nationalists and free marketeers continues.

  15. Unconventional attitudes: New thinking drives gas in south Alberta

    Energy Technology Data Exchange (ETDEWEB)

    Stonehouse, D.

    2002-05-01

    New natural gas wells under development and coming on stream in southern Alberta are discussed. These new wells are contrary to expectations since conventional wisdom holds that the future lies in the north frontier and the foothills of northwestern Alberta and northeastern British Columbia. Among these new developments are the wells of the Okotoks field which have been producing for years, but over 100 Bcf of gas remains to be exploited. The same company (Compton Petroleum Inc) is continuing to develop its deep gas Hooker play by drilling 15 successful wells in 2001 and acquiring additional land. The average stabilized rate on the Hooker wells is 1.7 MMcf/d, with expected decline rates of 10 per cent. West of Calgary Compton holds some more speculative opportunities on the Tsuu Tina Reserve and the Stoney Reserve. Impact Energy is another player generating interest in southern Alberta with its Whisky Creek play in the historic Turner Valley area. Impact Energy hit pay dirt at Whisky Creek last year with the 7-5 discovery well which is currently producing at a restricted rate of 5.0 MMcf/d with 50 bbl/MMcf of liquids. Two more wells in the play are expected to potentially add 30 Bcf of reserves, if successful. EnCana Energy and Quicksilver Resources subsidiary MGV Energy are also pushing the technological frontier with their coalbed methane play in the Palliser triangle in southeastern Alberta. A 250 well development is planned within the Palliser Block for later in 2002. Government figures put the potential for coalbed methane on Alberta's plains between 125 and 250 Tcf, more gas than remains in conventional reserves.

    Ambient air trends were assessed using data collected over an 8 year period from monitoring stations in Edmonton and Fort McKay, Alberta. In particular, the study evaluated the short term trends in the concentration of carbon monoxide (CO), nitrogen dioxide (NO{sub 2}), ozone (O{sub 3}), and particulate matter (PM{sub 2.5}) in Edmonton, as well as the NO{sub 2}, O{sub 3}, PM{sub 2.5}, and total hydrocarbons in Fort McKay. In order to evaluate the ambient air trends, this study examined the changes in concentrations of these pollutants between the 50 - 90 percentiles of concentration distributions for a calendar year. These statistics were assumed to be linear over the period of study and fitted using simple linear regression. Hypothesis tests were performed to determine if the slopes of the best-fit lines were greater or less than zero. There was no indication of a statistically significant short-term trend for NO{sub 2} and O{sub 3} for the city of Edmonton. However, statistically pronounced decreasing trends were noted for CO and PM{sub 2.5}. There was no indication of statistically significant trend for any of the pollutants examined at Fort McKay over the study period. It was cautioned that since the period of study over which trends were examined was short, the changes or lack of changes observed do not necessarily indicate long term trends. However, the results suggest that air quality has remained unchanged during the last 6 to 8 years, despite increased economic development in Edmonton and continued oil sands development in Fort McKay.

    The use of renewable energy resources is an essential feature in curtailing greenhouse gas (GHG) emissions. This paper discussed solar thermal water heating applications for Alberta. In particular, it presented a case study of the successful commercial application of solar thermal water heating systems in households in the city of Calgary. The system used solar-thermal collectors with heat pipes mounted inside vacuum sealed glass cylinders. The devices collected heat and transferred it to a copper manifold even in extreme winter temperatures. The system included a solar storage tank integrated into a domestic hot water system. The solar fluid circulated through the solar tank. Fresh cold water entered the solar tank when hot water was used in the house in order to be preheated before entering the original water heating tank. A 25 watt pump was mounted in the closed solar loop to circulate the solar heat transfer fluid. An economic analysis demonstrated that a 2-panel system saved the equivalent of 2.4 acres of carbon-absorbing forest and had the same benefit as purchasing a hybrid car. The payback period for the system was 4 years. It was concluded that solar thermal systems are the best renewable energy method for domestic water heating in Calgary. 10 refs., 2 tabs., 5 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.

    Full Text Available Abstract Background Musculoskeletal disorders (MSDs affect a large proportion of the Canadian population and present a huge problem that continues to strain primary healthcare resources. Currently, the Canadian healthcare system depicts a clinical care pathway for MSDs that is inefficient and ineffective. Therefore, a new inter-disciplinary team-based model of care for managing acute knee injuries was developed in Calgary, Alberta, Canada: the Calgary Acute Knee Injury Clinic (C-AKIC. The goal of this paper is to evaluate and report on the appropriateness, efficiency, and effectiveness of the C-AKIC through healthcare utilization and costs associated with acute knee injuries. Methods This quasi-experimental study measured and evaluated cost and utilization associated with specific healthcare services for patients presenting with acute knee injuries. The goal was to compare patients receiving care from two clinical care pathways: the existing pathway (i.e. comparison group and a new model, the C-AKIC (i.e. experimental group. This was accomplished through the use of a Healthcare Access and Patient Satisfaction Questionnaire (HAPSQ. Results Data from 138 questionnaires were analyzed in the experimental group and 136 in the comparison group. A post-hoc analysis determined that both groups were statistically similar in socio-demographic characteristics. With respect to utilization, patients receiving care through the C-AKIC used significantly less resources. Overall, patients receiving care through the C-AKIC incurred 37% of the cost of patients with knee injuries in the comparison group and significantly incurred less costs when compared to the comparison group. The total aggregate average cost for the C-AKIC group was $2,549.59 compared to $6,954.33 for the comparison group (p Conclusions The Calgary Acute Knee Injury Clinic was able to manage and treat knee injured patients for less cost than the existing state of healthcare delivery.

    This survey was conducted to measure the customer satisfaction of Calgary Transit users and gather information for further service improvements. The survey was conducted by telephone with a total of 500 current customers, and results were compared with previous surveys. The average number of trips per week among regular customers was 7.6, the lowest over the past 6 years. Twenty-six per cent of customers used the service more frequently due to higher gas prices, lack of a vehicle and the higher frequency of services. While most customers used buses, there was an increase in train usage in 2005, which was attributed to an increase in service frequency. Customers typically reported travelling during rush hour periods. Transit customers assigned a global score of 8.2 for service quality satisfaction and loyalty, which was consistent with previous scores. Seventy-two per cent of customers rated service quality as excellent or good. Approximately 1 in 5 customers perceived Calgary Transit to have improved over the previous year. Nearly half of the customers identified themselves as committed users of the service compared to other transportation methods, and most customers stated that having more service during peak hours and in new communities should be priorities. Sixty-four per cent of respondents supported fare increases to fund service additions. It was concluded that there was a significant increase in overall transit use in 2005, which may have been due to its perceived convenience and the influence of economic factors. It was noted that the increase has not affected customers' perceptions of service performance. 8 tabs., 9 figs.

  3. Context, cultural bias, and health risk perception: the "everyday" nature of pesticide policy preferences in London, Calgary, and Halifax.

    Risk perception and the cultural theory of risk have often been contrasted in relation to risk-related policy making; however, the local context in which risks are experienced, an important component of everyday decision making, remains understudied. What is unclear is the extent to which localized community beliefs and behaviors depend on larger belief systems about risk (i.e., worldviews). This article reports on a study designed to understand the relative importance of health risk perceptions (threat of harm); risk-related worldviews (cultural biases); and the experiences of local context (situated risk) for predicting risk-related policy preferences regarding cosmetic pesticides. Responses to a random telephone questionnaire are used to compare residents' risk perceptions, cultural biases, and pesticide bylaw preferences in Calgary (Alberta), Halifax (Nova Scotia), and London (Ontario), Canada. Logistic regression shows that the most important determinants of pesticide bylaw preference are risk perception, lack of benefit, and pesticide "abstinence." Though perception of health risk is the best single predictor of differences in bylaw preferences, social factors such as gender and situated risk factors like conflict over chemical pesticides, are also important. Though cultural biases are not important predictors of pesticide bylaw preference, as in other studies, they are significant predictors of health risk perception. Pesticide bylaw preference is therefore more than just a health risk perception or worldview issue; it is also about how health risk becomes situated-contextually-in the experiences of residents' everyday lives. © 2011 Society for Risk Analysis.

    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.

    The Alberta Sustainable Home is a new suburban three-bedroom house and office that will soon be independent of the sewer, electric, and water systems. Located in the cold, dry, sunny climate of Calgary, AB, the home is now demonstrating the feasibility of environmentally sustainable, cost-saving devices-from Eco-studs in the framework to graywater heat recovery devices. Although it was built for about the same price as a comparable conventional home, the Alberta Sustainable Home has received a preferential mortgage rate, is expected to have an unusually high resale value, and will cost about $1,500 per year (Canadian) less for utilities. The Alberta Sustainable Home was built privately by Autonomous and Sustainable Housing Incorporated (ASH), in partnership with some 215 companies worldwide. Construction began in September 1993, and the designers and builders have lived and worked in the building since April 1994. Topics include the following: space and water heating; airtight construction; insulation; windows; refrigeration; saving water; low embodied energy; retrofitting; pollutant control; less power.

    Guidelines have historically recommended measuring lipid profile tests in a fasting state. However, in April 2011 and 2014, the Canadian city of Calgary and its province of Alberta, respectively, have changed their lipid guidelines to allow testing for individuals in any fasting state; several years prior to the release of the 2016 Canadian Cardiovascular Society and Hypertension Canada guidelines. The purpose of this study was to document the proportion of individuals in Calgary who fasted for a lipid encounter in relation to the change in various guidelines and policies. Counts were collected each month per gender from January 1, 2010 to June 30, 2016 for community-based adults ≥18years old who fasted (≥8h) or did not fast (fasting state. The proportion of adults who fasted declined from 98.59%±0.379% (mean±SD) in 2010 to 41.65%±1.295% (mean±SD) in 2016. However, a marked decline in the proportion of adults fasting for a lipid encounter was not observed until February 2015, which coincided with the release of Alberta's Toward Optimized Practice Clinical Practice Guidelines. This documentation of individuals fasting for a lipid encounter may assist other jurisdictions in Canada with the new nonfasting lipid guideline changes. We recommend releasing provincial clinical practice guidelines, in addition to laboratory bulletins and continuing medical education presentations, regarding the new nonfasting lipid recommendations in other jurisdictions to ensure community patients are aware of this change.

    Alberta is Canada's largest oil producer and its oil sand deposits comprise 30% of the world's oil reserves. The process of bitumen extraction and upgrading releases trace gases and aerosols to the atmosphere. In this study we present satellite-based analysis to explore, for the first time, various contributing factors that affect tropospheric carbon monoxide (CO) levels over Alberta. The multispectral product that uses both near-infrared (NIR) and the thermal-infrared (TIR) radiances for CO retrieval from the Measurements of Pollution in the Troposphere (MOPITT) are examined for the 12 year period from 2002-2013. Moderate Resolution Imaging Spectroradiometer (MODIS) thermal anomaly product from 2001 to 2013 is employed to investigate the seasonal and temporal variations of forest fires. Additionally, in situ CO measurements at industrial and urban sites are compared to satellite data. Furthermore, the available MOZAIC/IAGOS (Measurement of Ozone, Water Vapor, Carbon Monoxide, Nitrogen Oxide by Airbus In-Service Aircraft/In service Aircraft for Global Observing System) aircraft CO profiles (April 2009-December 2011) are used to validate MOPITT CO data. The climatological time curtain plot and spatial maps for CO over northern Alberta indicate the signatures of transported CO for two distinct biomass burning seasons, summer and spring. Distinct seasonal patterns of CO at the urban site s (Edmonton and Calgary cities) point to the strong influence of traffic. Meteorological parameters play an important role on the CO spatial distribution at various pressure levels. Northern Alberta shows stronger upward lifting motion which leads to larger CO total column values while the poor dispersion in central and south Alberta exacerbates the surface CO pollution. Inter-annual variations of satellite data depict a slightly decreasing trend for both regions while the decline trend is more evident from ground observations, especially at the urban sites.

    Science.gov (United States)

    2013-07-19

    During October 2010-February 2011, an outbreak of 91 Salmonella Enteritidis (SE) infections in Alberta, Canada, was investigated by a local public health department (Alberta Health Services, Calgary Zone). Index cases initially were linked through a common history of consumption of food purchased from mobile food-vending vehicles (lunch trucks) operating at worksites in Alberta. Further investigation implicated one catering company that supplied items for the lunch trucks and other vendors. In 85 cases, patients reported consumption of food prepared by the catering company in the 7 days before illness. Six patients were employees of the catering company, and two food samples collected from the catering company were positive for SE. Foods likely were contaminated directly or indirectly through the use of illegally sourced, SE-contaminated eggs at the implicated catering facility and by catering employees who were infected with SE. Public health interventions put into place to control the outbreak included screening employees for Salmonella, excluding those infected from food-handling duties, and training employees in safe food-handling procedures. No further outbreak cases were identified after full implementation of the interventions. This investigation highlights the potential for lunch trucks to be a source of foodborne illness and the need for robust regulatory compliance monitoring of lunch trucks and their food suppliers.

  12. CBM split title in Alberta

    2006-07-01

    Coalbed methane (CBM) coal underlies most of central and southern Alberta. This article discussed disputes surrounding CBM ownership and split-titles. Historically, ownership of lands in Alberta implied possession and rights of all under- and overground substances. Surface estates are now typically separated from the subsurface estate, and subsurface estates are further divided either on the basis of substances or stratigraphically to create a split-title. Mineral severances are used to separate respective mineral rights among owners. While there is a relative certainty that under provincial Crown tenure CBM is included in natural gas tenure, there is currently no Canadian jurisprudence in respect of CBM entitlement on split-title private lands. Where compressed natural gas (CNG) and coal are separately held, and CBM ownership is not specifically addressed in the mineral severance, there is no Canadian law respecting CBM ownership. Resolution of ownership issues has proceeded on a case by case basis. Coal owners argue that there is a distinct interrelationship between CBM and its host coal strata. Gas owners argue that the chemical composition of CBM is identical to CNG, and that the recovery method is similar to that of CNG. Courts have historically applied the vernacular test to resolve mineral substance ownership disputes, which considers the meanings of the word coal and coalbed methane as defined by industry. The most recent and relevant application of the vernacular test were the Borys/Anderson, which effectively implemented a gas-oil interface ownership determination, which if applied to a coal grant or reservation, may lead to the conclusion that the coal strata includes CBM. It was concluded that there are 26,000 individual mineral owners in Alberta that may become involved in CBM litigation. and could become parties to litigation. refs., tabs., figs.

    To determine what proportion of women seeking induced abortion in the Calgary census metropolitan area were immigrants. For 2 months, eligible women were asked to complete a questionnaire. Women who refused were asked to provide their country of birth (COB) to assess for selection bias. Two abortion clinics in Calgary, Alta. Women presenting at or less than 15 weeks' gestational age for induced abortion for maternal indications. The primary outcome was the proportion of women seeking induced abortion services who were immigrants. Secondary outcomes compared socioeconomic characteristics and contraception use between immigrant and Canadian-born women. A total of 752 women either completed a questionnaire (78.6%) or provided their COB (21.4%). Overall, 28.9% of women living in the Calgary census metropolitan area who completed the questionnaire were immigrants, less than the 31.2% background proportion of immigrant women of childbearing age. However, 46.0% of women who provided only COB were immigrants. When these data were combined, 34.2% of women presenting for induced abortion identified as immigrant, a proportion not significantly different from the background proportion (P = .127). Immigrant women presenting for induced abortion tended to be older, more educated, married with children, and have increased parity. They were similar to Canadian-born women in number of previous abortions, income status, and employment status. This study suggests that immigrant women in Calgary are not presenting for induced abortion in disproportionately higher numbers, which differs from existing European literature. This is likely owing to differing socioeconomic characteristics among the immigrant women in our study from what have been previously described in the literature (typically lower socioeconomic status). Much still needs to be explored with regard to factors influencing the use of abortion services by immigrant women. Copyright© the College of Family Physicians of

    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.

Method: A qualitative approach, in which we interviewed six relatives of children who were admitted to an emergency hospital in Fortaleza, Ceara due to fall in the period from August to September, 2005. According to the CFAM we did the genogram and eco-map of two families (1 and (2. Results: By the genogram and eco-map of the families, we observed that (1 is a single parent family with six children, Roman Catholic, earns one minimum wage and attends both school and Family Health Basic Unit (UBSF. (2 is a nuclear family, with two children, Roman Catholic, earns three or more minimum wages and attends school, work and UBSF. Conclusion: The Calgary Family Assessment Model enabled to know the family structures of the children who had suffered falls and helped in defining the risk factors that exist within families and social environments in which these children attend. Family income, number of children, the presence or absence of fathers, schooling and lack of spaces for education support represent risk factors for these accidents.

    Dental caries (tooth decay) is common and can be serious. Dental caries is preventable, and community water fluoridation is one means of prevention. There is limited current research on the implications of fluoridation cessation for children's dental caries. Our objective was to explore the short-term impact of community water fluoridation cessation on children's dental caries, by examining change in caries experience in population-based samples of schoolchildren in two Canadian cities, one that discontinued community water fluoridation and one that retained it. We used a pre-post cross-sectional design. We examined dental caries indices (deft [number of decayed, extracted, or filled primary teeth] and DMFT [number of decayed, missing, or filled permanent teeth]) among grade 2 schoolchildren in 2004/05 and 2013/14 in two similar cities in the province of Alberta, Canada: Calgary (cessation of community water fluoridation in 2011) and Edmonton (still fluoridated). We compared change over time in the two cities. For Calgary only, we had a third data point from 2009/10, and we considered trends across the three points. We observed a worsening in primary tooth caries (deft) in Calgary and Edmonton, but changes in Edmonton were less consistent and smaller. This effect was robust to adjustment for covariates available in 2013/14 and was consistent with estimates of total fluoride intake from biomarkers from a subsample. This finding occurred despite indication that treatment activities appeared better in Calgary. The worsening was not observed for permanent teeth. For prevalence estimates only (% with >0 deft or DMFT), the three data points in Calgary suggest a trend that, though small, appears consistent with an adverse effect of fluoridation cessation. Our results suggest an increase in dental caries in primary teeth during a time period when community fluoridation was ceased. That we did not observe a worsening for permanent teeth in the comparative analysis could

    The difference between surface and mineral rights in Alberta was defined. Surface rights give ownership of the surface of the land and the right to work it. Mineral rights, on the other hand, give ownership and the right to explore and develop or extract minerals beneath the surface. Oil and gas are the most common minerals in Alberta, however, gold, silver, uranium and salt are also included under mineral rights. Sand, gravel, clay, marl and peat, are excluded. The conditions which apply to the mineral owner`s right to explore and develop were summarized. Some case studies of appeals to the court regarding mineral and surface right were presented as illustrations.

    Bitumen extraction from the oil sands of Alberta has resulted in millions of cubic meters of waste stored on-site in tailings ponds. Unique microbial ecology is expected in these ponds, which may be key to their bioremediation potential. We considered that direct culturing of microbes from a tailings sample as biofilms could lead to the recovery of microbial communities that provide good representation of the ecology of the tailings. Culturing of mixed species biofilms in vitro using the Calgary Biofilm Device (CBD) under aerobic, microaerobic, and anaerobic growth conditions was successful both with and without the addition of various growth nutrients. Denaturant gradient gel electrophoresis and 16S rRNA gene pyrotag sequencing revealed that unique mixed biofilm communities were recovered under each incubation condition, with the dominant species belonging to Pseudomonas, Thauera, Hydrogenophaga, Rhodoferax, and Acidovorax. This work used an approach that allowed organisms to grow as a biofilm directly from a sample collected of their environment, and the biofilms cultivated in vitro were representative of the endogenous environmental community. For the first time, representative environmental mixed species biofilms have been isolated and grown under laboratory conditions from an oil sands tailings pond environment and a description of their composition is provided.

    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 Government of Alberta continues to improve delivery of healthcare by allowing Albertans to access their health information online. Alberta is the only province in Canada with provincial electronic health records for all its citizens. These records are currently made available to medical practitioners, but Alberta Health believes that providing Albertans access to their health records will transform the delivery of healthcare in Alberta. It is important to have a high level of assurance that the health records are provided to the correct Albertan. Alberta Health requires a way for Albertans to obtain a digital identity with a high level of identity assurance prior to releasing health records via the Personal Health Portal. Service Alberta developed the MyAlberta Digital ID program to provide a digital identity verification service. The Ministry of Health is leveraging MyAlberta Digital ID to enable Albertans to access their personal health records through the Personal Health Portal. The Government of Alberta is advancing its vision of patient-centred healthcare by enabling Albertans to access a trusted source for health information and their electronic health records using a secure digital identity.

    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.

  1. Real Time Estimation of the Calgary Floods Using Limited Remote Sensing Data

    Directory of Open Access Journals (Sweden)

    Emily Schnebele

    2014-02-01

    Full Text Available Every year, flood disasters are responsible for widespread destruction and loss of human life. Remote sensing data are capable of providing valuable, synoptic coverage of flood events but are not always available because of satellite revisit limitations, obstructions from cloud cover or vegetation canopy, or expense. In addition, knowledge of road accessibility is imperative during all phases of a flood event. In June 2013, the City of Calgary experienced sudden and extensive flooding but lacked comprehensive remote sensing coverage. Using this event as a case study, this work illustrates how data from non-authoritative sources are used to augment traditional data and methods to estimate flood extent and identify affected roads during a flood disaster. The application of these data, which may have varying resolutions and uncertainities, provide an estimation of flood extent when traditional data and methods are lacking or incomplete. When flooding occurs over multiple days, it is possible to construct an estimate of the advancement and recession of the flood event. Non-authoritative sources also provide flood information at the micro-level, which can be difficult to capture from remote sensing data; however, the distibution and quantity of data collected from these sources will affect the quality of the flood estimations.

    An exploratory spatial analysis investigates the location of schools in Calgary (Canada) in relation to air pollution and active transportation options. Air pollution exhibits marked spatial variation throughout the city, along with distinct spatial patterns in summer and winter; however, all school locations lie within low to moderate pollution levels. Conversely, the study shows that almost half of the schools lie in low walkability locations; likewise, transitability is low for 60% of schools, and only bikability is widespread, with 93% of schools in very bikable locations. School locations are subsequently categorized by pollution exposure and active transportation options. This analysis identifies and maps schools according to two levels of concern: schools in car-dependent locations and relatively high pollution; and schools in locations conducive of active transportation, yet exposed to relatively high pollution. The findings can be mapped and effectively communicated to the public, health practitioners, and school boards. The study contributes with an explicitly spatial approach to the intra-urban public health literature. Developed for a moderately polluted city, the methods can be extended to more severely polluted environments, to assist in developing spatial public health policies to improve respiratory outcomes, neurodevelopment, and metabolic and attention disorders in school-aged children.

    The adequacy of the Calgary biofilm device, often referred to as the MBEC system, as a high-throughput approach to the production and subsequent characterization of Pleurotus ostreatus biofilms was assessed. The hydroxyapatite-coating of pegs was necessary to enable biofilm attachment, and the standardization of vegetative inocula ensured a uniform distribution of P. ostreatus biofilms, which is necessary for high-throughput evaluations of several antimicrobials and exposure conditions. Scanning electron microscopy showed surface-associated growth, the occurrence of a complex aggregated growth organized in multilayers or hyphal bundles, and the encasement of hyphae within an extracellular matrix (ECM), the extent of which increased with time. Chemical analyses showed that biofilms differed from free-floating cultures for their higher contents of total sugars (TS) and ECM, with the latter being mainly composed of TS and, to a lesser extent, protein. Confocal laser scanning microscopy analysis of 4-day-old biofilms showed the presence of interspersed interstitial voids and water channels in the mycelial network, the density and compactness of which increased after a 7-day incubation, with the novel occurrence of ECM aggregates with an α-glucan moiety. In 4- and 7-day-old biofilms, tolerance to cadmium was increased by factors of 3.2 and 11.1, respectively, compared to coeval free-floating counterparts.

    2003-08-01

    Communication skills training is now internationally accepted as an essential component of medical education. However, learners and teachers in communication skills programs continue to experience problems integrating communication with other clinical skills, ensuring that clinical faculty support and teach communication beyond the formal communication course, extending communication training coherently into clerkship and residency, and applying communication skills in medical practice at a professional level of competence. One factor contributing to these problems is that learners confront two apparently conflicting models of the medical interview: a communication model describing the process of the interview and the "traditional medical history" describing the content of the interview. The resulting confusion exacerbates the above dilemmas and interferes with learners using communication skills training to advantage in real-life practice. The authors propose a comprehensive clinical method that explicitly integrates traditional clinical method with effective communication skills. To implement this more comprehensive approach, they have modified their own Calgary-Cambridge guides to the medical interview by developing three diagrams that visually and conceptually improve the way communication skills teaching is introduced and that place communication process skills within a comprehensive clinical method; devising a content guide for medical interviewing that is more closely aligned with the structure and process skills used in communication skills training; and incorporating patient-centered medicine into both process and content aspects of the medical interview. These enhancements help resolve ongoing difficulties associated with both teaching communication skills and applying them effectively in medical practice.

    Assessing timeliness and completeness of vaccine administration is important for evaluating the effectiveness of immunization programs. Few studies have reported timeliness, particularly in Canada. The objective of this study was to examine timeliness of the receipt of vaccination for each routine childhood recommended vaccine by 24 months of age among children in a community-based pregnancy cohort in Calgary, Alberta. Survey data from a community-based pregnancy cohort in Alberta were linked to Public Health vaccination records of children (n = 2763). The proportion of children receiving early, timely, delayed, or no vaccination was calculated. A dose was considered early if it was administered before the recommended age in days as per the vaccination schedule, timely if administered at any time from start of recommended age in days to age in days when delay counts were initiated, and delayed if it was administered on or after age in days when delay counts were initiated. Series completion rates were also calculated. For multi-dose vaccines, over 80% of children had timely doses at 2, 4 and 6 months. By 12 months, this proportion decreased to 65% (95% CI: 63%-66%) for meningococcal conjugate group C, 61% (95% CI: 59%-62%) for measles antigen-containing vaccines and 64% (95% CI: 62%-65%) for varicella antigen-containing vaccines. At 18 months, only 55% (95% CI: 53%-56%) of the children had a timely 4th dose of diphtheria, acellular pertussis, tetanus, polio, and Haemophilus influenzae type b vaccine. Eventual series completion rate for all recommended vaccines was 77% (95% CI: 75%-79%). The timeliness and completeness of routine childhood vaccination in preschool children in this community-based pregnancy cohort is lower than provincial targets. Data on timeliness of vaccination can inform further work on barriers and enablers to vaccination in order to meet provincial targets.

    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)

    This study aimed to evaluate the trends and regional variation of stroke hospital care in 30-day in-hospital mortality, hospital length of stay (LOS), and 1-year total hospitalization cost after implementation of the Alberta Provincial Stroke Strategy. New ischemic stroke patients (N = 7632) admitted to Alberta acute care hospitals between 2006 and 2011 were followed for 1 year. We analyzed in-hospital mortality with logistic regression, LOS with negative binomial regression, and the hospital costs with generalized gamma model (log link). The risk-adjusted results were compared over years and between zones using observed/expected results. The risk-adjusted mortality rates decreased from 12.6% in 2006/2007 to 9.9% in 2010/2011. The regional variations in mortality decreased from 8.3% units in 2008/2009 to 5.6 in 2010/2011. The LOS of the first episode dropped significantly in 2010/2011 after a 4-year slight increase. The regional variation in LOS was 15.5 days in 2006/2007 and decreased to 10.9 days in 2010/2011. The 1-year hospitalization cost increased initially, and then kept on declining during the last 3 years. The South and Calgary zones had the lowest costs over the study period. However, this gap was diminishing. After implementation of the Alberta Provincial Stroke Strategy, both mortality and hospital costs demonstrated a decreasing trend during the later years of study. The LOS increased slightly during the first 4 years but had a significant drop at the last year. In general, the regional variations in all 3 indicators had a diminishing trend.

    Full Text Available Objetivou-se avaliar a estrutura, o desenvolvimento e o funcionamento da família de uma adolescente grávida. Pesquisa qualitativa, do tipo estudo de caso, realizado de fevereiro a abril/2008. Os cenários da pesquisa foram uma associação habitacional, em Fortaleza-CE-Brasil, e o domicílio da adolescente. Os dados foram coletados e analisados com fundamentação no Modelo Calgary de Avaliação da Família. Como resultados, constatou-se no aspecto estrutural que a família apresenta uma situação de instabilidade financeira, agravada pelo nascimento da criança. Quanto ao aspecto “desenvolvimental” da família, percebeu-se uma alteração, devido à gravidez não planejada da adolescente. No aspecto funcional, a gestação impediu a adolescente de continuar com algumas atividades extracurriculares. Os outros membros, também, modificaram suas rotinas para amparar a adolescente no cuidado ao filho. A aplicação do Modelo Calgary possibilitou avaliar a família em todos os aspectos, permitindo traçar intervenções que mudaram a realidade e amenizaram os problemas da família em estudo.

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

    Energy Technology Data Exchange (ETDEWEB)

    Bachmann, G. [Canadian Gas and Electric Inc., Calgary, AB (Canada)

    2001-07-01

    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.

  19. A Comprehensive Land-Use/Hydrological Modeling System for Scenario Simulations in the Elbow River Watershed, Alberta, Canada

    The Elbow River watershed in Alberta covers an area of 1,238 km2 and represents an important source of water for irrigation and municipal use. In addition to being located within the driest area of southern Canada, it is also subjected to considerable pressure for land development due to the rapid population growth in the City of Calgary. In this study, a comprehensive modeling system was developed to investigate the impact of past and future land-use changes on hydrological processes considering the complex surface-groundwater interactions existing in the watershed. Specifically, a spatially explicit land-use change model was coupled with MIKE SHE/MIKE 11, a distributed physically based catchment and channel flow model. Following a rigorous sensitivity analysis along with the calibration and validation of these models, four land-use change scenarios were simulated from 2010 to 2031: business as usual (BAU), new development concentrated within the Rocky View County (RV-LUC) and in Bragg Creek (BC-LUC), respectively, and development based on projected population growth (P-LUC). The simulation results reveal that the rapid urbanization and deforestation create an increase in overland flow, and a decrease in evapotranspiration (ET), baseflow, and infiltration mainly in the east sub-catchment of the watershed. The land-use scenarios affect the hydrology of the watershed differently. This study is the most comprehensive investigation of its nature done so far in the Elbow River watershed. The results obtained are in accordance with similar studies conducted in Canadian contexts. The proposed modeling system represents a unique and flexible framework for investigating a variety of water related sustainability issues.

    1982-11-01

    The Occupational Hygiene Branch of Alberta Workers' Health, Safety and Compensation conducted a comprehensive study of the foundry industry in Alberta. The surveys assessed both the degree of health hazards present and the effectiveness of existing control systems for airborne contaminants. All nine of Alberta's ferrous foundries were surveyed in the course of the project. The foundries varied from those which were small with limited mechanization to those which were large and highly automated. The concentrations of free silica in the work environment are correlated to the different attempts to control silica using substitution and various ventilation systems. The particular foundry processes evaluated for airborne free silica were sand preparation, shakeout, dry sand transport and sand molding. Workers' exposure to free airborne silica was evaluated by personal and area samples. The free silica content of the samples was determined by infra-red spectrophotometry. The results indicated most control systems were inadequate. Effective control methods are described to reduce the health hazard.

    The difference between surface and mineral rights in Alberta was defined. By definition, surface rights give ownership only to the surface of the land and the right to work it. Mineral rights in contrast give ownership and the right to explore and develop or extract minerals beneath the surface. Oil and gas are the most common minerals in Alberta, however, gold silver, uranium and salt are also included under mineral rights, but sand, gravel, clay, marl and peat, are not. Conditions which limit the mineral owner`s right to explore and develop were summarized. Some case studies of appeals to the court regarding mineral and surface rights were presented.

  9. Coal-bed methane in Alberta : ownership and incidental production

    Energy Technology Data Exchange (ETDEWEB)

    Rogers, A.

    2006-04-05

    Some of the challenges facing the emerging coal-bed methane (CBM) industry in Alberta include concerns regarding water protection, compression noise, well spacing and fracturing issues. One of the most fundamental questions regarding CBM is who in fact owns the resource and what rules oversee its production. The characteristics, development potential and origins of split title ownership of CBM in North America were examined in this paper. The history of freehold and Crown-owned land and the law regarding ownership and incidental production of petroleum, natural gas and bitumen in split-title situations were reviewed. The legal status of CBM in other jurisdictions was also examined. The issues of ownership and incidental production in Alberta were also discussed. The basic common law ownership principles regarding mineral ownership were applied to the characteristics of CBM in situ to conclude its possible owner in Alberta. The extension of established incidental mineral production principles to CBM were examined in the context of its characteristics. The official governmental position on CBM issues and the prospect of future legislative intervention were identified and the implications for industry and resource companies were also presented. The paper presented several recommendations including that Alberta should legislate to eliminate any right of recovery for historical or current venting of CBM during coal mining in order to remove a cloud of uncertainty over the industry. refs.

  14. Development of Greenhouse Gas Mitigation Options for Alberta's Energy Sector

    Science.gov (United States)

    Subramanyam, Veena

    Alberta is the third largest economy in Canada and is expected to grow significantly in the coming decade. The energy sector plays a major role in Alberta's economy. The objective of this research is to develop various greenhouse gas (GHG) mitigations scenarios in the energy demand and supply sectors for the Province of Alberta. This is done through an energy-environment planning and forecasting tool called Long Range Energy Alternative Planning system model (LEAP). By using LEAP, a sankey diagram for energy and emission flows for the Province of Alberta has been developed. A reference case also called as business-as-usual scenario was developed for a study period of 25 years (2005-2030). The GHG mitigation scenarios encompassed various demand and supply side scenarios. In the energy conversion sector, mitigation scenarios for renewable power generation and inclusion of supercritical, ultra-supercritical and integrated gasification combined cycle (IGCC) plants were investigated. In the oil and gas sector, GHG mitigation scenarios with carbon capture and sequestration (CCS) option were considered. In Alberta's residential and commercial sector 4-6 MT of CO2 equivalents per year of GHG mitigation could be achieved with efficiency improvement. In the industrial sector up to 40 MT of CO2 equivalents per year of GHG reduction could be achieved with efficiency improvement. In the energy conversion sector large GHG mitigation potential lies in the oil and gas sector and also in power plants with carbon capture and storage (CCS) option. The total GHG mitigation possible in the supply side option is between 20--70 MT CO2 equivalents per year.

  15. Applicability of the Calgary-Cambridge Guide to Dog and Cat Owners for Teaching Veterinary Clinical Communications.

    Englar, Ryane E; Williams, Melanie; Weingand, Kurt

    2016-01-01

    Effective communication in health care benefits patients. Medical and veterinary schools not only have a responsibility to teach communication skills, the American Veterinary Medical Association (AVMA) Council on Education (COE) requires that communication be taught in all accredited colleges of veterinary medicine. However, the best strategy for designing a communications curriculum is unclear. The Calgary-Cambridge Guide (CCG) is one of many models developed in human medicine as an evidence-based approach to structuring the clinical consultation through 71 communication skills. The model has been revised by Radford et al. (2006) for use in veterinary curricula; however, the best approach for veterinary educators to teach communication remains to be determined. This qualitative study investigated if one adaptation of the CCG currently taught at Midwestern University College of Veterinary Medicine (MWU CVM) fulfills client expectations of what constitutes clinically effective communication. Two focus groups (cat owners and dog owners) were conducted with a total of 13 participants to identify common themes in veterinary communication. Participants compared communication skills they valued to those taught by MWU CVM. The results indicated that while the CCG skills that MWU CVM adopted are applicable to cat and dog owners, they are not comprehensive. Participants expressed the need to expand the skillset to include compassionate transparency and unconditional positive regard. Participants also expressed different communication needs that were attributed to the species of companion animal owned.

    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.

    1996-01-01

    OBJECTIVE: To determine whether the opinions of Alberta physicians about active euthanasia had changed and to assess the determinants of potential changes in opinion. DESIGN: Follow-up survey (mailed questionnaire) of physicians included in the 1991 Alberta Euthanasia Survey. SETTING: Alberta. PARTICIPANTS: Of the 1391 physicians who participated in the 1991 survey 1291 (93%) had indicated that they were willing to take part in a follow-up survey. A follow-up questionnaire was mailed in 1994 to 1146 physicians who could be traced through the 1994 Medical Directory of the provincial college of physicians and surgeons; 25 questionnaires were returned because they could not be delivered. OUTCOME MEASURES: Physicians' opinions about (a) the morality of active euthanasia, (b) changes in the law to permit active euthanasia and (c) the practice of legalized euthanasia. RESULTS: Of the 1121 physicians sent a follow-up questionnaire 866 (77%) returned it completed. The responses of these same 866 physicians in 1991 provided a basis for comparison. Of the 866, 360 (42%) stated in the 1994 survey that it is sometimes right to practise active euthanasia; a similar proportion (384 [44%]) gave this response in 1991. However, other opinions changed significantly. In 1991, 250 of the respondents (29%) indicated that they would practise active euthanasia if it were legalized, as compared with 128 (15%) in 1994 (p euthanasia, as compared with 316 (37%) in 1994 (p euthanasia between 1991 and 1994, in both surveys at least 70% of those who responded to this question indicated that active euthanasia, if it were legalized, should be performed only by physicians and should be taught at medical sites. CONCLUSION: Alberta physicians' support for the practice and legalization of active euthanasia decreased considerably between 1991 and 1994. However, most physicians remain in favour of restricting active euthanasia, if it were legalized, to the medical profession. These results suggest a

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. Methods/Design 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. Discussion 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.

  2. Alberta's and Ontario's liquor boards: why such divergent outcomes?

    2010-01-01

    The provinces of Alberta and Ontario have chosen very different methods to distribute alcoholic beverages: Alberta privatized the Alberta Liquor Control Board (ALCB) in 1993 and established a private market to sell beverage alcohol, while Ontario, in stark contrast, opted to retain and expand the Liquor Control Board of Ontario (LCBO). This article examines the reasons for the divergent policy choices made by Ralph Klein and Mike Harris' Conservative governments in each province. The article draws on John Kingdon's “multiple streams decision-making model,” to examine the mindsets of the key decision-makers, as well as “historical institutionalism,” to organize the pertinent structural, historical and institutional variables that shaped the milieu in which decision-makers acted. Unique, province-specific political cultures, histories, institutional configurations (including the relative influence of a number of powerful actors), as well as the fact that the two liquor control boards were on opposing trajectories towards their ultimate fates, help to explain the different decisions made by each government. Endogenous preference construction in this sector, furthermore, implies that each system is able to satisfy all relevant stakeholders, including consumers.

  3. 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

    'One World, One Health' is a foundation concept in veterinary medicine, much like comparative medicine. However, teachers of veterinary medicine often fail to identify it or speak of its importance within the veterinary curriculum. The resurgence of interest in the 'One World, One Health' concept aligns well with the underlying principles on which the University of Calgary Faculty of Veterinary Medicine (UCVM) has been newly founded. This concept is therefore a key component of the UCVM programme, and one that is well highlighted for those studying in the Doctor of Veterinary Medicine (DVM) course and graduate students.

    Verma, M.; Cook, T.

    2010-01-01

    Reserve growth is recognized as a major component of additions to reserves in most oil provinces around the world, particularly in mature provinces. It takes place as a result of the discovery of new pools/reservoirs and extensions of known pools within existing fields, improved knowledge of reservoirs over time leading to a change in estimates of original oil-in-place, and improvement in recovery factor through the application of new technology, such as enhanced oil recovery methods, horizontal/multilateral drilling, and 4D seismic. A reserve growth study was conducted on oil pools in Alberta, Canada, with the following objectives: 1) evaluate historical oil reserve data in order to assess the potential for future reserve growth; 2) develop reserve growth models/ functions to help forecast hydrocarbon volumes; 3) study reserve growth sensitivity to various parameters (for example, pool size, porosity, and oil gravity); and 4) compare reserve growth in oil pools and fields in Alberta with those from other large petroleum provinces around the world. The reported known recoverable oil exclusive of Athabasca oil sands in Alberta increased from 4.5 billion barrels of oil (BBO) in 1960 to 17 BBO in 2005. Some of the pools that were included in the existing database were excluded from the present study for lack of adequate data. Therefore, the known recoverable oil increased from 4.2 to 13.9 BBO over the period from 1960 through 2005, with new discoveries contributing 3.7 BBO and reserve growth adding 6 BBO. This reserve growth took place mostly in pools with more than 125,000 barrels of known recoverable oil. Pools with light oil accounted for most of the total known oil volume, therefore reflecting the overall pool growth. Smaller pools, in contrast, shrank in their total recoverable volumes over the years. Pools with heavy oil (gravity less than 20o API) make up only a small share (3.8 percent) of the total recoverable oil; they showed a 23-fold growth compared to

  17. 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

  1. Corporate social responsibility motives and theories evidenced among oilwell drilling firms in Alberta

    Science.gov (United States)

    Altvater, Norbert

    This dissertation is a study in conceptual CSR motives and theories prompted by the knowledge that socially active NGOs have tried to influence the CSP of companies in Alberta's oil patch by using media pressure. The focus of the study was narrowed to changing CSP among Alberta's oilwell drilling firms. This permits intensive interviews with the firms' informants. The examination of changing CSP implies a consideration of the pressures that prompt and influence its change, and points this study to firm motives for behaving responsibly. The firms were firstly categorized according to their primary and secondary CSP using 5 dimensions of CSR previously used by The Conference Board of Canada. The study uses CSR motives conceptualized by Ruth Aguilera and her collaborators to assess the firms' CSP using self-assessed CSR motives and observed CSP. At the onset 3 working hypotheses were posited as starting points from which substantiated propositions were developed. Lance Moir's and Elisabet Garriga and Domènec Meld's classifications of CSR theories were used to organize and evaluate the data. A mapping of the motives and theories in respect of the firms' primary and secondary CSR dimensions appears to display correlations between the CSR theories and the conceptualized motives. Nevertheless, for some of the firms none of the motives conceptualized by Aguilera and her collaborators seem to apply. By re-visiting the motives, and examining them more closely, it seems possible refine the conceptualized motives relying more on perceived conceptions, which are at the basis of legitimacy theories, rather than on relational factors to better explain the normative expectations raised. A similar analysis also indicates that the firms' seem to seek economic benefits, social benefits, or a combination of both. The CSP that results is within the same continuum; the resulting CSP for the firms seems to mediate towards a blend of both, regardless of the original CSR motives. These

Conclusion: The Calgary Family Assessment Model enabled to know the family structures of the children who had suffered falls and helped in defining the risk factors that exist within families and social environments in which these children attend. Family income, number of children, the presence or absence of fathers, schooling and lack of spaces for education support represent risk factors for these accidents.

  3. Sage-grouse habitat selection during winter in Alberta

    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.

    Some of the activities associated with the Environmental Impact Assessment (EIA) process in oil sands operations in Alberta were reviewed with particular reference to key regional issues such as instream flow needs (IFN), basal water management, lake acidification potential, and climate change. The proven approaches to maintain timelines and maximize success were also discussed with reference to the factors that can be managed to promote an efficient application, review and approval process. It was noted that although the EIA process is well-defined and robust, it is evolving due to new challenges such as increasingly complex tools and new regulations. Alberta's Cumulative Environmental Management Association (CEMA) continuously refines environmental objectives for NOx, SOx, surface water, and the Muskeg River and the Athabasca River watersheds. In particular, much effort has gone into determining the water withdrawals from the Athabasca River during the winter months and its effect on resident fish populations. Operators must determine the viability of a project if studies of IFN indicate that there is limited river flow available for abstraction. This paper identified several factors that can be addressed to keep the process on schedule. These include planning, understanding issues, completing baseline surveys, and commanding the attention of regulators. 12 refs., 1 tab., 8 figs.

    This paper proposed a method of extending the utility of bioclimatic envelope models for land use planning and adaptation under climate change. The trajectory of vegetation changes was set by the model, while the rate of transition was determined using a disturbance model. The method was used to explore potential changes to the distribution of ecosystems in Alberta under various climate and disturbance scenarios. The study showed that use of the disturbance model slowed the rate of ecosystem transition when compared with the results obtained from the bioclimatic envelope model alone. A northward shift of grasslands into large areas of existing parklands occurred over the simulation's 50-year time period. Between 12 and 21 per cent of Alberta's Boreal region was converted to parklands. Boreal transitions will initially occur in forests adjacent to current parklands and spread outwards. Fires over 100 km {sup 2} provided an indication of the anticipated size of potential transition patches. It was concluded that using a disturbance model to quantify transition logs can improve uncertainties in the parameter estimates of bioclimatic envelope models. 43 refs., 3 tabs., 3 figs.

    Full Text Available Abstract Background Most cases of echinococcal disease (ED acquired in Canada are thought to be due to the sylvatic form of Echinococcus granulosus, which may be more benign than ED due to either Echinococcus multilocularis or the pastoral form of E. granulosus. There are limited descriptions of the clinical course and outcome of Canadian patients with ED in the modern era. Methods A retrospective chart review was performed of patients hospitalized with echinococcal disease (ED from 1991 to 2001 in Edmonton, Alberta. Results Forty-two cases of ED were identified of which 19 were definite, 3 probable, and 20 possible. Further analysis was limited to the 22 definite and probable cases, of which 77% were female and 41% aboriginal, with an age range of 5 to 87 years. Nine patients (40% had pulmonary involvement and 11 (50% hepatic involvement. One patient had an intracardiac mass presenting as a cerebrovascular event and one had a splenic cyst. Seven of the 22 patients had combined surgical resection and medical treatment, six had surgical resection of the cyst alone, four had cyst aspiration, one had medical treatment alone and four had no specific treatment. There was no mortality attributable to ED but three patients died of unrelated illnesses. Conclusion Echinococcal disease in northern Alberta has a marked diversity of clinical presentations, and generally has a good prognosis despite a wide variety of therapeutic interventions.

    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

    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.

    1995-12-31

    Drilling waste disposal sites are one of the most difficult sites to reclaim in the oil and gas industry, due to contamination of the site with heavy oils and salts. The fundamental principle of well site reclamation is the return of a disturbed site to a land capability equivalent to the pre-disturbance land capability, which is sustainable under normal management of the land. A list of legislative requirements for reclamation in Alberta was provided. Steps involved in bioremediation were discussed. The concept of landfarming as a drilling waste disposal option for heavy invert mud systems over a selected plot of land, was introduced. Although theoretically landfarming can take place in either the topsoil or subsoil, studies have shown that topsoil provides a more favourable environment for microbial biodegradation of the hydrocarbons contained in invert drilling muds. 7 refs., 1 fig.

    1980-01-01

    Hydrocarbons, both oil and gas, have been discovered in the basal quartz formation in the Manyberries area of SE Alberta. Estimation of producible fluids and hydrocarbons in place has been difficult due to the very shaly nature of the reservoir rock. Calculations of water saturation with no corrections for clay conductivity underestimates the hydrocarbons in place. The Waxman-Smits evaluation technique, which provides a method to account for clay conductivities, was used to estimate water saturation based on total porosity. Work of other authors provides a technique to correlate total and effective porosities. This was used to estimate effective porosity and subsequently water saturation based on the effective porosity. Error analysis was undertaken to estimate the uncertainty in the calculated water saturations.

  12. Legal issues concerning oilfield waste management in Alberta

    1998-12-31

    The Alberta Energy and Utilities Board (EUB) is the regulatory authority with regard to oilfield wastes and oilfield waste management facilities. This presentation provided an overview of existing legislation and regulations in this area. Highlights of EUB Guide 58, and the application of the release of substances and contaminated sites provisions of the Environmental Protection and Enhancement Act (EPEA) regarding oilfield wastes and oilfield waste management facilities were also discussed. Generators, transporters and receivers of oilfield waste are potentially liable under the EPEA if oilfield wastes are released into the environment. Liabilities could imply clean-up orders, fines or penalties. The offences, penalties and enforcements of two acts, the Gas Conservation Act and the Environmental Protection and Enhancement Act, were compared.

  13. Alberta Consumers' Valuation of Extrinsic and Intrinsic Red Meat Attributes

    2010-01-01

    This paper analyzes Alberta consumers’ perceptions toward extrinsic and intrinsic attributes of bison and beef steaks. In contrast to published Canadian consumer studies on bison meat that were undertaken prior to May 2003, before the first BSE case of Canadian origin was identified in beef cattle......, this study provides a “post-BSE” assessment of consumer perceptions toward selected bison meat attributes. The results from an attribute-based choice experiment provide little support that simple traceability assurance schemes have value to consumers of bison and beef steaks, thus confirming similar findings...... of earlier beef studies that have employed different methodological approaches. The results also suggest that consumers are willing to pay significant premiums for bison steaks that are certified as being produced without genetically modified organisms, an attribute that has so far been unexplored...

  14. Sustainable water management in Alberta's oil sands

    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.

    In the summer of 2013, an aircraft measurement campaign led by Environment Canada with participation from university researchers took place to investigate the sources and transformations of gas pollutants in the Alberta oil sands region close to Fort McMurray, Alberta. Apart from its ability to change the radiative forcing of the atmosphere, methane is also a significant precursor to the formation of formaldehyde, an important radical source. Thus, emissions of methane from facilities need to be understood since they can have air quality implications through alteration of the radical budget and hence, the oxidation capacity of the air mass. Methane was measured, along with other gases, via a cavity ring-down spectroscopy instrument installed on the Convair-580 aircraft. In total, there were 22 flights with 82 hours of measurements in the vicinity of oil sands facilities between August 13 and September 7, 2013. Various tools have been used to visualize the spatial and temporal variation in mixing ratios of methane and other trace gases in order to identify possible sources of methane. Enhancements of methane from background levels of 1.9 ppm up to ~4 ppm were observed close to energy mining facilities in the oil sands region. Sources of methane identified include open pit mining, tailings ponds, upgrader stacks and in-situ mining operations. Quantification of the emission rates of methane from distinct sources has been accomplished from box flights and downwind screen flights by identifying the ratios of trace gases emitted and through use of the Top-down Emission Rate Retrieval Algorithm (TERRA). Methane emission rates for some of these sources will be presented.

    Full Text Available For several years, the government of the western Canadian province of Alberta has drafted policies and conducted research on the problem of populations under-represented in adult education. This Alberta-North and Athabasca University study, funded by the Alberta government’s Innovation Fund, uses the advice and educational experiences of northern former and present students, and of other community members, to identify ways of better attracting, preparing, and retaining under-represented populations in northern Alberta communities through provision and training in the use of distance delivery methods.The research reported here commences with a review of the literature to investigate the following: 1 the contribution distance education makes globally to learning access in remote areas (and resulting economic growth for under-served populations; 2 how support is provided to retain isolated students; and 3 the help needed to assist remote students to complete distance programs. Community consultations with social service and education agencies in three communities were conducted in order to obtain their perspectives about what helps to attract and support students to educational programs and the barriers students typically encounter, which might be mitigated by distance methods. Finally, a survey was designed and distributed in 87 Alberta-North communities in northern Alberta and across Canada’s Northwest Territories to add perspective to the consultation results.

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

    Directory of Open Access Journals (Sweden)

    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.

    A mobile system was used for continuous ambient measurements of stable CH4 isotopes (12CH4 and 13CH4) and ethane (C2H6). This system was used during a winter mobile campaign to investigate the CH4 isotopic signatures and the C2H6/CH4 ratios of the main anthropogenic sources of CH4 in the Canadian province of Alberta. Individual signatures were derived from δ13CH4 and C2H6 measurements in plumes arriving from identifiable single sources. Methane emissions from beef cattle feedlots (n = 2) and landfill (n = 1) had δ13CH4 signatures of -66.7 ± 2.4‰ and -55.3 ± 0.2‰, respectively. The CH4 emissions associated with the oil or gas industry had distinct δ13CH4 signatures, depending on the formation process. Emissions from oil storage tanks (n = 5) had δ13CH4 signatures ranging from -54.9 ± 2.9‰ to -60.6 ± 0.6‰ and non-detectable C2H6, characteristic of secondary microbial methanogenesis in oil-bearing reservoirs. In contrast, CH4 emissions associated with natural gas facilities (n = 8) had δ13CH4 signatures ranging from -41.7 ± 0.7‰ to -49.7 ± 0.7‰ and C2H6/CH4 molar ratios of 0.10 for raw natural gas to 0.04 for processed/refined natural gas, consistent with thermogenic origins. These isotopic signatures and C2H6/CH4 ratios have been used for source discrimination in the weekly atmospheric measurements of stable CH4 isotopes over a two-month winter period at the Lac La Biche (LLB) measurement station, located in Alberta, approximately 200 km northeast of Edmonton. The average signature of -59.5 ± 1.4‰ observed at LLB is likely associated with transport of air after passing over oil industry sources located south of the station.

  14. A characterization of solution gas flaring in Alberta.

    Science.gov (United States)

    Johnson, M R; Kostiuk, L W; Spangelo, J L

    2001-08-01

    Information reported here is the result of a detailed analysis of data on flared and vented solution gas in the Province of Alberta in 1999. A goal of characterizing these flares was to aid in the improved management of solution gas flaring. In total, 4499 oil and bitumen batteries reported flaring or venting with a combined gas volume of 1.42 billion m3. There was significant site-to-site variation in volumes of gas flared or vented, gas composition, and flare design. Approximately 5% of physical batteries generate 35.7% of the gas flared and vented from oil and bitumen batteries. Therefore, if one were to attempt to mitigate flaring, significant progress could be made by starting with only the largest sites. The monthly variability of gas volumes was considered because high variability could affect implementation of alternative technologies. It was found that slightly more than 40% of the sites were reasonably steady and had monthly deviations of 100% or less from the average flared volume. The variability in monthly volumes was less for the larger batteries. Data from individual well sites show significant variability in the relative concentrations of each of the major species contained in solution gas.

    Rubella IgG levels for 157,763 pregnant women residing in Alberta between 2009 and 2012 were analyzed. As there have been no reported cases of indigenous rubella infection in Canada since 2005, there has been a lack of naturally acquired immunity, and the current prenatal population depends almost entirely on vaccine induced immunity for protection. Rubella antibody levels are significantly lower in younger maternal cohorts with 16.8% of those born prior to universal vaccination programs (1971-1980), and 33.8% of those born after (1981-1990) having IgG levels that are not considered protective (rubella containing vaccine. These discordant interpretations generate a great deal of confusion for laboratorians and physicians alike, and result in significant patient follow-up by Public Health teams. To assess the current antibody levels in the prenatal population, latent class modeling was employed to generate a two class fit model representing women with an antibody response to rubella, and women without an antibody response. The declining level of vaccine-induced antibodies in our population is disconcerting, and a combined approach from the laboratory and Public Health may be required to provide appropriate follow up for women who are truly susceptible to rubella infection.

  16. Aeromagnetics of southern Alberta within areas of hydrocarbon accumulation

    Leblanc, G. E.; Morris, W. A. [McMaster Univ., School of Geography and Geology, Hamilton, ON (Canada)

    1999-12-01

    The relationship between the observed geomagnetic field and hydrocarbon pools is investigated by reviewing the sources of magnetic anomalies in sedimentary basins and the methods for isolating individual contributions, with specific reference to noise suppression. A recent high resolution aeromagnetic survey acquired by the Geological Survey of Canada in southern Alberta is used as the test case to demonstrate the method and the potential of aeromagnetic surveys to resolve structural controls on hydrocarbon emplacement. The investigation was undertaken in an effort to account for the fact that several features of the residual magnetic field appear to be common to a majority of hydrocarbon pools. Some of these commonalities are: (1) the long axis of the pool appears to be coincident with the strike of the basement-sourced magnetic signal, (2) hydrocarbon pools encompass areas of broad low amplitude magnetic anomalies, (3) cross-cutting fractures or faulting systems are located within areas of a majority of hydrocarbon pools, and (4) pools are associated with linear and/or curvilinear magnetic lineaments, of which a great number have topographic expression. These associations may arise as a result of eH/pH conditions of the hydrocarbons and the surrounding sediments, or they may arise purely as a result of the trapping structures. The physical extent of the interaction area of the pool with the surrounding sediment may be another factor in explaining the association of hydrocarbons and magnetics. 48 refs., 9 figs.

    The characteristics of lightning and the relationship between lightning and transmission line outages is not fully understood by utility planners. This study used 20 year data sets of lightning events to investigate the spatial and temporal patterns of lightning in Alberta. Studies of geographical and temporal characteristics of lightning caused transmission line outages for several voltage level transmission lines were also examined. A lasso regression variable selection procedure and Cp criterion were used to model the duration of the lightning-caused transmission line outages as a function of weather and lightning patterns. The province was divided into 110 by 110 grids, and lightning variables were calculated for each cell. All the lightning variables for each cell were then averaged based on their areas. The overall cloud-ground lightning flashes 20-year mean frequency and the physical locations of power transmission lines were then plotted. Estimated probability density functions of the duration of lightning caused transmission line outages were classified by their voltage levels. The study showed that the characteristics of the lightning caused outages were different for different voltage levels of the transmission lines. Results suggested that the findings will have a significant impact on the accuracy of reliability methodologies that use the average duration of transmission line outages in their calculations. It was concluded that the new methodology can be applied to any transmission line system operating in a unique geographical environmental area. 11 refs., 3 tabs., 5 figs.

    2014-12-01

    The rapid expansion of oil sands activities and massive energy requirements to extract and upgrade the bitumen require a comprehensive understanding of their potential environmental impacts, particularly on air quality. In this study, satellite-based analysis of carbon monoxide (CO) levels was used to assess the magnitude and distribution of this pollutant throughout Alberta oil sands region. Measurements of Pollution in the Troposphere (MOPITT) V5 multispectral product that uses both near-infrared and the thermal-infrared radiances for CO retrieval were used. MOPITT-based climatology and inter-annual variations were examined for 12 years (2002-2013) on spatial and temporal scales. Seasonal climatological maps for CO total columns indicated conspicuous spatial variations in all seasons except in winter where the CO spatial variations are less prominent. High CO loadings are observed to extend from the North East to North West regions of Alberta, with highest values in spring. The CO mixing ratios at the surface level in winter and spring seasons exhibited dissimilar spatial distribution pattern where the enhancements are detected in south eastern rather than northern Alberta. Analyzing spatial distributions of Omega at 850 mb pressure level for four seasons implied that, conditions in northeastern Alberta are more favorable for up lofting while in southern Alberta, subsidence of CO emissions are more likely. Time altitude CO profile climatology as well as the inter-annual variability were investigated for the oil sands and main urban regions in Alberta to assess the impact of various sources on CO loading. Monthly variations over urban regions are consistent with the general seasonal cycle of CO in Northern Hemisphere which exhibits significant enhancement in winter and spring, and minimum mixing ratios in summer. The typical seasonal CO variations over the oil sands region are less prominent. This study has demonstrated the potential use of multispectral CO

  1. Fertility in Alberta in a Context of Rapid Economic Growth, 1997-2007

    Directory of Open Access Journals (Sweden)

    2010-01-01

    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 sub-replacement 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 lead to reduced fertility.

    2007-07-01

    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.

  4. Governance in Transformation: Alberta School Board Chairs’ Perspectives on Governance

    Full Text Available School boards are typically removed from nonprofit sector analyses because they are part of the “MUSH” set of organizations (municipalities, universities, schools, and hospitals that both stand outside of the more typical nonprofit sector and tend to be closely affiliated with government. Nevertheless, school boards offer a unique opportunity to examine the governance of a large system of regulated activity that affects millions of citizens. How such systems should be governed has been a matter of concern for nearly 40 years. This study presents data from Alberta school board chairs regarding their perception of governance transformation being brought about by legislative changes. Five dimensions of governance are proposed as defining the current and anticipated governance domain within which school boards operate. Tensions within and between these dimensions signify symbolic boundary constructions that need to be scrutinized in anticipation of the governance transformation and boundary spanning activities of school boards required by the new legislation. / Les conseils scolaires sont généralement retirés des analyses du secteur communautaire parce qu’ils font partie de l’ensemble d’organisations « MUSH » (les municipalités, les universités, les écoles et les hôpitaux; ces organisations se distinguent du secteur communautaire typique et ont tendance à être étroitement associées au gouvernement. Néanmoins, les conseils scolaires offrent une occasion unique d’observer la gouvernance d’un vaste système d’activités réglementées qui affecte des millions de citoyens. La façon dont de tels systèmes devraient être gérés fait l’objet de préoccupations depuis presque 40 ans. Cette étude présente les perceptions de présidents de conseils scolaires de l’Alberta en ce qui a trait à la transformation de la gouvernance apportée par des modifications à la loi.

  5. Porosity and Velocity Relations of Grosmont Formation, Alberta, Canada

    2010-12-01

    We present results on porosty-velocity relations of Grosmont formation, Alberta, Canada, which is one of largest bitumen carbonate reservoirs. Grosmont formation is divided into four units: LG; UG-1; UG-2; and UG-3 from the bottom. Two lower units are mainly imestone, while upper units are mostly dolomite with vuggy porosity and fractures, which makes the upper units be a good reservoir. Rock physics modeling was then performed to quantify porosity-velocity relations for the four units, which enables us to predict porosity from seismic data. To incorporate the pore-scale details in the modeling, we used DEM (differential effective medium) models. Two lower units are very similar in velocity-porosity domain, thus the relations can be represented by one velocity-porosity model, which is used as our reference model. For the UG-2 unit, we found that one model cannot represent the unit since the degree of fracturing are heterogeneous from location to location. We thus suggested three different DEM models for the UG-2 unit: vuggy-dominant; mildly-fractured; and heavily-fractured. The UG-3 units can be modeled with vuggy porosity, and fractures were not very noticeable. We also investigated the spatial variation of the UG-2 unit, and found that the degree of fracturing is generally proportional to the proximity to the unconformity boundary, where the fresh water invasion can be dominant. In conclusion, we proposed velocity-porosity relations for the four units in Grosmont formation, and believe that these models can help to characterize the reservoir quality. In addition, since the proximity of reservoir to the unconformity boundary highly affects the degree of fracturing, a careful analysis of spatial variation would be essential for the successful characterization of Grosmont formation.

    The University of Alberta High Altitude Balloon (UA-HAB) program is a one and half year program sponsored by the Canadian Space Agency (CSA) that offers hands on experience for undergraduate and graduate students in the design, build, test and flight of an experimental payload on a high altitude balloon platform. Utilising low cost weather balloon platforms, and through utilisation of the CSA David Florida Laboratory for thermal-vacuum tests , in advance of the final flight of the payload on a NASA high altitude balloon platform. Collectively the program provided unique opportunities for students to experience mission phases which parallel those of a space satellite mission. The program has facilitated several weather balloon missions, which additionally provide educational opportunities for university students and staff, as well as outreach opportunities among junior and senior high school students. Weather balloon missions provide a cheap and quick alternative to suborbital missions; they can be used to test components for more expensive missions, as well as to host student based projects from different disciplines such as Earth and Atmospheric Sciences (EAS), Physics, and Engineering. In addition to extensive skills development, the program aims to promote recruitment of graduate and undergraduate students into careers in space science and engineering. Results from the UA-HAB program and the flight of the UA-HAB shielded Gieger counter payload for cosmic ray and space radiation studies will be presented. Lessons learned from developing and maintaining a weather balloon program will also be discussed. This project is undertaken in partnership with the High Altitude Student Platform, organized by Louisiana State University and the Louisiana Space Consortium (LaSpace), and sponsored by NASA, with the financial support of the Canadian Space Agency.

    A rapid method for screening the metabolic susceptibility of biofilms to toxic compounds was developed by combining the Calgary Biofilm Device (MBEC device) and Phenotype MicroArray (PM) technology. The method was developed using Pseudomonas alcaliphila 34, a Cr(VI)-hyper-resistant bacterium, as the test organism. P. alcaliphila produced a robust biofilm after incubation for 16 h, reaching the maximum value after incubation for 24 h (9.4 × 10(6) ± 3.3 × 10(6) CFU peg(-1)). In order to detect the metabolic activity of cells in the biofilm, dye E (5×) and menadione sodium bisulphate (100 μM) were selected for redox detection chemistry, because they produced a high colorimetric yield in response to bacterial metabolism (340.4 ± 6.9 Omnilog Arbitrary Units). This combined approach, which avoids the limitations of traditional plate counts, was validated by testing the susceptibility of P. alcaliphila biofilm to 22 toxic compounds. For each compound the concentration level that significantly lowered the metabolic activity of the biofilm was identified. Chemical sensitivity analysis of the planktonic culture was also performed, allowing comparison of the metabolic susceptibility patterns of biofilm and planktonic cultures.

    In an effort to understand the extent of the inequalities in health information resources across Alberta, SEARCH Custom, HKN (Health Knowledge Network) and IRREN (Inter-Regional Research and Evaluation Network) conducted a survey in December 2007 to determine what library resources currently existed in Alberta's seven rural health regions and the two urban health regions. Although anecdotal evidence indicated that these gaps existed, the analysis was undertaken to provide empirical evidence of the exact nature of these gaps. The results, coupled with the published literature on the impact, effectiveness and value of information on clinical practice and administrative decisions in healthcare management, will be used to build momentum among relevant stakeholders to support a vision of equitably funded health information for all healthcare practitioners across the province of Alberta.

  9. Reflexive modernization at the source: local media coverage of bovine spongiform encephalopathy in rural Alberta.

    Davidson, Debra J; Bogdan, Eva

    2010-11-01

    The potential for reflexive modernization is defined by multiple factors, but the acknowledgment of risk is crucial, particularly among social groups that play a key role in risk minimization. This study offers an examination of the role of local media in response to the outbreak of bovine spongiform encephalopathy (BSE) in beef-producing communities in rural Alberta. BSE is one of several global risk issues that reflexive modernization theorists argue have the potential to trigger a transformation toward a critically reflexive society in which such risks are minimized. Content analysis of newspapers in beef-producing regions in Alberta, however, shows how local media framed BSE in a manner that maximized community cohesion and protection of local culture. This selective coverage of BSE in rural Alberta is quite likely to have contributed to, or at least reinforced, support for the current institutional structure of Canadian agriculture in beef-producing regions, through the constriction of discourse.

    2011-07-01

    Canada is endowed with important fossil fuel resources, most of them are located in Alberta's oil sands and heavy oil reservoirs. Although these deposits are considered as some of the most challenging ones to develop, most of them can now be economically exploited thanks to public policy approaches which have promoted innovation. The aim of the paper is to present the different public policies implemented in Alberta over the last century and to show the approaches employed to develop Alberta's crude depending upon the circumstances. This paper reviewed the different innovation directions taken in the past. The author stated that social and environmental objectives will have increasing importance in the future and that innovation will therefore be required to achieve these objectives. This paper presented the approaches applied in the past and concluded that more resources will need to be put into research and innovation in the future to meet the objectives.

    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

    Background Five cases of severe neutropenia (neutrophil counts < 0.5 per 109 cells/L) associated with exposure to cocaine and levamisole, an antihelimithic agent no longer available in Canada, were identified in Alberta in 2008. Alberta and British Columbia (BC) public health officials issued an advisory and urged health care professionals to report cases to public health. This paper presents the findings of the public health investigations. Methods Cases were identified prospectively through reporting by clinicians and a retrospective review of laboratory and medical examiners data from January 1, 2006 to March 31, 2009. Cases were categorized as confirmed, probable or suspect. Only the confirmed and probable cases are included in this paper. Results We compare cases of severe neutropenia associated with tainted cocaine (NATC) identified in Alberta and BC between January 1, 2008 to March 31, 2009. Of the 42 NATC cases: 23(55%) were from Alberta; 19(45%) were from British Columbia; 57% of these cases reported crack cocaine use (93% of those who identified type of cocaine used); 7% reported using cocaine powder; and the main route of cocaine administration was from smoking (72%). Fifty percent of the NATC cases had multiple episodes of neutropenia associated with cocaine use. Cases typically presented with bacterial/fungal infections and fever. One Alberta NATC case produced anti-neutrophil antibodies, and four were positive for anti-neutrophil cytoplasmic antibody (ANCA). Analysis of two crack pipes and one drug sample obtained from NATC cases confirmed the presence of both cocaine and levamisole. A further 18 cases were identified through the retrospective review of laboratory and medical examiner data in Alberta Interpretation Our findings support a link between neutropenia and levamisole tainted cocaine; particularly from smoking the crack form of cocaine. Some patients may be genetically predisposed to develop levamisole-related neutropenia. Awareness of the

    OBJECTIVE: To ascertain the opinions of a sample of Alberta physicians about the morality and legalization of active euthanasia, the determinants of these opinions and the frequency and sources of requests for assistance in active euthanasia. DESIGN: Cross-sectional survey of a random sample of Alberta physicians, grouped by site and type of practice. SETTING: Alberta. PARTICIPANTS: A total of 2002 (46%) of the licensed physicians in Alberta were mailed a 38-item questionnaire in May through July 1991; usable responses were returned by 1391 (69%). RESULTS: Of the respondents 44% did believe that it is sometimes right to practice active euthanasia; 46% did not. Moral acceptance of active euthanasia correlated with type of practice and religious affiliation and activity. In all, 28% of the physicians stated that they would practice active euthanasia if it were legalized, and 51% indicated that they would not. These opinions were significantly related to sex, religious affiliation and activity, and country of graduation. Just over half (51%) of the respondents stated that the law should be changed to permit patients to request active euthanasia. Requests (usually from patients) were reportedly received by 19% of the physicians, 78% of whom received fewer than five. CONCLUSIONS: This survey revealed severely disparate opinions among Alberta physicians about the morality of active euthanasia. In particular, religious affiliation and activity were associated with the polarized opinions. The desire for active euthanasia, as inferred from requests by patients, was not frequent. Overall, there was no strong support expressed by the physicians for the personal practice of legalized active euthanasia. These data will be vital to those involved in health education and public policy formation about active euthanasia in Alberta and the rest of Canada. PMID:8500029

    Streptococcus pneumoniae is a pathogen causing acute respiratory infections, as well as meningitis and bacteremia. The province of Alberta, Canada, began vaccinating infants against seven S. pneumoniae serotypes in 2002 using Prevnar 7 (PCV7). However, a 13-valent conjugate vaccine (PCV13) was introduced in 2010 to address changes in the distribution of serotypes causing disease. PCV13 targets 13 serotypes including six additional serotypes to the previously adopted PCV7. In this study, we estimate the impact of the new PCV13 immunization program on the burden of disease and related healthcare costs in Alberta. Serotype-specific passive surveillance invasive pneumococcal disease (IPD) data were drawn from the Alberta Public Health Laboratory. These data were used to estimate average annual IPD incidence of the six additional serotypes included in PCV13 during the PCV7 era (2000-2009), and after the introduction of PCV13 (2011-2015). The difference in estimated cases pre-/post-PCV13 was used to estimate associated changes in direct health service costs. Following the replacement of PCV7 with PCV13 in 2010, the number of cases of IPD caused by the additional serotypes contained in PCV13 has declined significantly across all ages. The expected number of IPD cases prevented annually is an estimated 1.6 per 100,000. Direct health service costs are expected to be averted as a result of the implementation of PCV13 universal vaccination in Alberta. Indirect benefits are experienced by ages >20 years as IPD incidence significantly declines following the PCV13 infant immunization in Alberta. The impact on direct healthcare costs of replacing PCV7 with PCV13 in Alberta's public immunization program are estimated to be CAN$3.5 million as of 2015.

    Full Text Available Abstract Background 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. Methods 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. Results 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

    Reported prevalence rates of chronic rhinosinusitis (CRS) range from 1% to 12% worldwide. To facilitate appropriate health service delivery and resource allocation, it is important to improve the estimated burden of CRS to the health care system. To assess the prevalence and incidence of diagnosed CRS in Alberta, Canada, from the perspective of the health care system and to evaluate the 10-year temporal trend and geographic variation of diagnosed CRS. From provincial-wide physicians' claim data, a CRS cohort was identified using a validated case definition. The population at the midpoint (2008-2009) of the study period (2 925 930) was used as the reference. The crude as well as age- and sex-standardized incidence and prevalence rates were calculated. The age-specific incidence and prevalence by sex were also assessed in each study year. Small-area variation analysis was conducted using extremal quotient, weighted coefficient of variation, χ2 statistic, systematic component of variation, and empirical Bayes variance estimate. Of the 2 925 930 individuals in the study at midpoint (2008-2009), 1 451 261 (49.6%) were women, and the mean (SD) age was 45 (17) years. From fiscal year 2004-2005 to fiscal year 2013-2014, the mean age- and sex-standardized incidence of diagnosed CRS was 2.5 (range, 2.3-2.7) per 1000 population. The estimated prevalence based on age-specific incidence varied between 18.8 (95% CI, 18.7-18.9) and 23.3 (95% CI, 23.1-23.5) per 1000 population during 2004-2005 to 2013-2014, and no obvious growing trend was found. There was high geographic variation in the diagnosed incidence and prevalence of CRS (mean systematic component of variation, 19.4 and 12.3, respectively). Although the incidence and prevalence rates of diagnosed CRS were lower compared with earlier published estimates obtained from population-based survey analysis, outcomes from this study may more accurately reflect the disease burden of CRS to the health care system.

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

    Directory of Open Access Journals (Sweden)

    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

    This commemorative Alberta centennial edition presents a series of articles exploring the history of the oil and gas industry in Alberta. The infancy of the oil and gas business was highlighted, with reference to the Turner Valley Conservation Act, which helped to build the framework for the creation of the Alberta Petroleum and Natural Gas Conservation Board, the predecessor of today's Energy and Utilities Board. A timeline of events linking world history with industry events was presented throughout the edition. Articles included: stories about oil and gas booms; exploration; the effects of World War 1 and 2; the first oil sands refineries; and the Great Depression. Political figures and business figures were also featured, as well as the early successes of businesses such as the Lloydminster Gas Company. Events of historic importance to the oil and gas industry, such as the Leduc discovery were also highlighted. The National Energy Program, low prices and economic recession were examined. Policy and regional reaction to Federal directives were also featured. Some companies advertised their services in this document, namely: Precision Drilling Corp; Halliburton; Wellco Energy Services Inc.; Gibson Energy Ltd.; National Oilwell; Lufkin; Ferus Gas Industries Trust; Rigstar; Safety Boss Inc.; and Esso. refs., tabs., figs.

  5. Of goats, sheep, camels and oil : two Calgary lawyers are helping government officials in Somalia and Kurdistan design new petroleum laws

    Lorenz, A.W.

    2007-05-15

    A few international energy companies have shown strong interest in the northern regions of Somalia for the exploration of oil, particularly since Somalia shares geological trends with Yemen and Sudan, both of which have prolific hydrocarbon basins. Two Calgary lawyers have been working with the government of Somalia in developing a new set of oil and gas laws. After decades of repression, Iraq's Kurdish Regional Government (KRG) has now asked one of the lawyers to also help develop their laws. Unlike the Somalis who live in a region where hydrocarbons have barely been explored, the Kurds live in a mountainous region with one of the world's largest hydrocarbon basins. The lawyers began by teaching the Somalis the basics of petroleum legal practices and designing Somalia's new system. This article emphasized that the task of creating a foundation for the petroleum legal system is quite similar for both regions, in terms of who is entitled to the resource and how much will be shared with foreign companies in return for investment and expertise. The Somalis have asked for advice on the best way to divide profits between the state and the foreign investor. This article also discussed the political challenges facing the Kurds in terms of negotiating their own exploration and development contracts in Iraq. One of the greatest challenges is that when a new Iraq National Oil Company was created, it was given basically every current field in the country, even those in Kurdistan. While oil companies prefer concession regimes, Iraq offers 3 different types of contracts, namely Production Sharing Agreements, service contracts and risk exploration contracts. 4 figs.

  11. Controls on the distribution of non-hydrocarbon gases in the Alberta Basin

    Energy Technology Data Exchange (ETDEWEB)

    Hutcheon, I. [Calgary Univ., Dept, of Geology and Geophysics, AB (Canada)

    1999-12-01

    Patterns of the occurrence of the non-hydrocarbon gases hydrogen sulfide, carbon dioxide, helium and nitrogen in the Alberta Basin was investigated. Results show that hydrogen sulfide and carbon dioxide tend to increase to the west and with depth in Devonian and Mississippian strata. Concentrations are higher than in the Cretaceous units. Nitrogen and to some degree helium, tend to show an antipathetic relationship with high hydrogen sulfide and carbon dioxide in Devonian and Mississippian strata. Helium concentrations are relatively high in north central Alberta in the Devonian, and in southern Alberta in the Mannville. Nitrogen in southern Alberta is higher at shallow depths in the Mannville and Colorado groups. Hydrogen sulfide and carbon dioxide is considered to be the product of thermal reduction of sulphate, probably derived from Devonian anhydrite. In the Mannville group hydrogen sulfide is the product of the bacterial reduction of sulphate, driven by incursion of meteoric water from the south that causes mixing of waters from Mississippian carbonate rocks with waters from Mannville elastic rocks. Carbon dioxide in the Colorado group is believed to have been formed by oxidation of organic matter, while the helium observed in the Devonian stratum is likely the result of the mixing of deep crustal rock with atmospheric sources. Correlations with hydrocarbon gases in the Colorado Group suggests that the high nitrogen content is related to bacterial accumulation of natural gas. 63 refs., 36 figs.

    The purpose of this study was to review data from the province of Alberta, Canada for First Nations children who required more than 1 general anesthesia (GA) procedure for dental surgery from 1996 to 2005. This study was limited to First Nations and Inuit children younger than 18 years old in Alberta who received 2 or more GA procedures to facilitate dental treatment Data spanning 1996 to 2005 were provided from the Alberta Regional Office of First Nations & Inuit Health Branch, Health Canada. The entire database contained claims for 339 children who received repeat GA procedures for rehabilitative dental core. Seventy-six percent received 2 procedures, while the remainder underwent 3 or more surgeries. Twenty-four percent of First Nations children in this cohort were subjected to >2 GA procedures. Retreatment of previously restored teeth was a common observation. The majority of children were treated by general practitioners instead of pediatric dentists. Seventy-four percent who had 2 or more surgeries were treated by general dentists at the time of the first GA procedure. The mean age of children at the time of the first GA procedure was not associated with whether children received 2 or more GA procedures for dental care (P=.07). These data suggest that there may be on over-reliance on GA to treat dental caries for First Notions children in Alberta.

    2005-11-01

    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.

    2011-12-01

    As part of the Helmholtz-Alberta Initiative (HAI), a major initial goal is to undertake a critical study of the potential for Engineered Geothermal Systems (EGS) as a source of thermal energy in northern Alberta. The geology of this area consists to first order as westward thickening wedge of Cretaceous siliclastics overlying Devonian carbonates and evaporites all of which lies upon the metamorphic Canadian Shield craton. Generally, the north eastern of Alberta is characterized by low geothermal gradients (near 20 mK/m) and temperatures; and deep drilling to as much as 4-5 km into the craton will be necessary to obtain requisite conditions (i.e. 80-100 C water at the source). Consequently, at this early stage it is important to search for zones with the greatest potential; and in the context of EGS this can mean finding greater fracture permeability through pre-existing faults and joint systems. State of stress information is also being considered as this will be an important constraint on fluid flow in such fractured systems. Current studies are integrating reprocessed legacy industrial and LITHOPROBE seismic reflection profiles, high-resolution aeromagnetic and gravity surveys, and existing borehole and core data are used to develop regional geophysical and geological models of Northern Alberta. Particular areas will focus on structural and tectonic linkages between the sedimentary basin and the underlying craton that are possibly related to, for example, Devonian reef complexes, extensive karsting, or evaporite collapse.

    Energy Technology Data Exchange (ETDEWEB)

    Wills, J.; Sultan, R. [Waterline Resources Inc. (Canada)

    2011-07-01

    In the oil and gas industry, water is a critical component of production; in Alberta, 75% of oil production is water-assisted. The use of water in Alberta is regulated by two organisms, Alberta Environment (AENV) and the Energy Resources and Conservation Board (ERCB), with the goal of sustainable management of water resources. AENV regulates the use of non-saline water by the industry and the ERCB regulates access to saline water for energy projects. Non-saline water is defined as having a concentration of less than 4,000 mg/L of total dissolved solids and saline water as having a concentration above 4,000mg/L. The regulatory framework is in constant evolution and the aim of this paper is to provide detail and clarity on the current and future situations. This paper highlights current and emerging regulations on water use in Alberta so that industrial operators can better understand what is and will be asked of them.

  9. 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

    2011-09-01

    Full Text Available Woodland caribou (Rangifer tarandus are classified as threatened in Alberta. In support of Canada's Species at Risk Act, a Recovery Plan for Woodland Caribou in Alberta was completed in 2004 which required local implementation plans to be completed within 5 areas of the province. The West Central Alberta Caribou Landscape Plan (WCCLP is the first of these to be initiated and it addresses the recovery strategies for 4 herds. Two aspatial computer models built on the STELLA© modelling platform (ISee Systems, 2007 were used to assist the planning team in evaluating cumulative effects and alternative scenarios for caribou conservation. The ALCES© (Forem Technologies 2008 modelling tool was used to forecast potential changes in the west central Alberta landscape over time. Yearly landscape condition outputs from ALCES© were then exported into a caribou-specific population model, REMUS© (Weclaw, 2004, that was used to project potential population responses by woodland caribou, other primary prey species [moose (Alces alces, elk (Cervus elaphus and deer (Odocoileus sp.] and wolves (Canis lupus (Weclaw & Hudson, 2004. Simulated habitat management strategies that resulted in the highest likelihood of caribou recovery included the maintenance of a high proportion of old forest, the aggregation of industrial footprints and the reclamation of historic seismic lines (although the latter took decades to provide real dividends. Sharing of industrial roads, protection of fragments of old-growth, and expanding an already aggressive fire control strategy in Alberta had little additional effect on caribou recovery. Simulated population management strategies that were successful all involved decades of intensive wolf control, either directly or indirectly through intensive primary prey control (with the exception of woodland caribou until old-growth forests recovered to densities that provided caribou habitat and decreased alternate prey of wolves.

    Science.gov (United States)

    Hiyagon, H.; Kennedy, B. M.

    1992-04-01

    The elemental and isotopic compositions of helium, neon, argon, and xenon in twenty-one CH 4-rich natural gas samples from Cretaceous and Devonian reservoirs in the Alberta, Canada, sedimentary basin were measured. In all but a few cases, radiogenic ( 4He, 40Ar, and 131-136Xe) and nucleogenic ( 21,22Ne) isotopes dominated. Based solely on the noble gas composition, two types of natural gas reservoirs are identified. One (Group B) is highly enriched in radiogenic-nucleogenic noble gases and varies little in composition: 3He /4He = 1.5 ± 0.5 × 10 -8, 40Ar /36Ar = 5000-6500 , 40∗Ar /4He = 0.10 , 136∗Xe /4He ~ 0.7 × 10 -9, and 21∗Ne /22∗Ne = 0.452 ± 0.041 (∗ denotes radiogenic or nucleogenic origin; all 4He is radiogenic). High nitrogen content with 4He /N 2 ~ 0.06 is also characteristic of Group B samples. The remaining samples (Group A) contain a radiogenic-nucleogenic component with a different composition and, relative to Group B samples, the extent of enrichment in this component is less and more variable: 3He /4He = 10-70 × 10 -8, 40Ar /36Ar Precambrian basement, consistent with a present-day mass flux into the overlying sedimentary basin. Inferred 40∗Ar /136∗Xe 4He ratios imply a basement source enriched in thorium relative to uranium and potassium (Th/U > 20). Combined, the overall lower total radiogenic-nucleogenic content of Group A reservoirs, the greater variability in composition, and the appearance of Group A noble gases in reservoirs higher in the sedimentary sequence relative to the underlying basement implies that the Group A radiogenic-nucleogenic noble gases are indigenous to the sediments. The most interesting aspect of the Group A noble gases are the very high 3He /4He ratios; ~ 10-70 times greater than expected if derived from average crust. The mantle, surface cosmogenic 3He production, cosmic dust, or production in a lithium-enriched environment as potential sources for the 3He excesses are evaluated. The present data set

    Pang, Xiaoli L; Lee, Bonita E; Tyrrell, Gregory J; Preiksaitis, Jutta K

    2009-02-15

    This study describes the epidemiology and circulating strains of sapovirus associated with gastroenteritis outbreaks in Alberta, Canada, from 2004 to 2007. Sapovirus was an important cause of gastroenteritis outbreaks, accounting for 43 (17.6%) of 244 outbreaks in which all samples tested were negative for norovirus. All 4 human sapovirus genotypes, GI, GII, GIV, and GV, were found in samples during these outbreaks. The greatest amount of sapovirus-associated outbreak activity occurred in 2007, after the emergence of genotype GIV in December 2006. The majority of sapovirus-associated outbreaks in Alberta during this period (27 [62.8%] of 43) occurred in hospitals, community long-term care facilities, and senior lodges. Adults>65 years of age were the age group most commonly affected.

  1. Transformism in Alberta: The Environmental Political Economy of the Bituminous Sands

    Science.gov (United States)

    Katz-Rosene, Ryan

    This thesis attempts to help establish environmental political economy as a viable academic field while providing an example of work in the discipline. It offers an analysis of societal processes resulting in the co-optation and/or neutralization of critical environmentalist ideas. Using Alberta's bituminous sands as a case study, and a Gramsci-influenced eco-Marxist theory as a foundation, the thesis argues that the term 'environmental transformism' (inspired by the Gramscian term trasformismo) is helpful in describing and framing such processes. Accordingly, the ensuing chapters provide an analysis of why environmental transformism is happening in Alberta, and demonstrate how this mechanism works at protecting the status quo from threatening ideologies, thereby consolidating neoliberal capitalism. A concluding argument discusses the inherent dangers posed to society by the transformism of certain environmental subjectivities. The thesis begins by introducing the contentious social and environmental issues surrounding the development of the bituminous sands.

    The sharp improvement in the export performance of Western Canada in recent years was discussed. In 1995, British Columbia ranked first among western provinces in the value of exports, and Alberta ranked second. Shipments from Alberta increased 15.4 per cent in value over 1994. The two provinces account for approximately 80 per cent of Western Canada`s total. A summary was provided of the increased value of exports for certain categories (meat, vegetables, energy, plastics, wood, electrical machinery, furniture, precision instruments); all of these meet the criteria defined for `sustained growth` and `export foothold`. Western Canada`s trade with Mexico was also discussed. All exports from Western Canada were itemized,along with export and U.S. market shares data from 1988 to 1995. 11 tabs.

    Peat cores were collected from six bogs in northern Alberta to reconstruct changes in the atmospheric deposition of Pb, a valuable tracer of human activities. In each profile, the maximum Pb enrichment is found well below the surface. Radiometric age dating using three independent approaches (14C measurements of plant macrofossils combined with the atmospheric bomb pulse curve, plus 210Pb confirmed using the fallout radionuclides 137Cs and 241Am) showed that Pb contamination has been in decline for decades. Today, the surface layers of these bogs are comparable in composition to the "cleanest" peat samples ever found in the Northern Hemisphere, from a Swiss bog ~ 6000 to 9000 years old. The lack of contemporary Pb contamination in the Alberta bogs is testimony to successful international efforts of the past decades to reduce anthropogenic emissions of this potentially toxic metal to the atmosphere.

    Alberta's Turner Valley has a history of oilfield development from the 1910s to the 1940s. This presentation provided a brief history of the Turner Valley area and discussed the remediation of Miracle number 3 well site and remediation of Okalta number 22 well site. Urban development near the historical wells was also discussed. Many photos were presented to provide context to the area and oil oilfield development. Specific topics that were discussed regarding Miracle number 3 well included environmental site assessments; soil gas testing; remediation; remedial excavation; and in situ remediation. Regarding Okalta number 22 well site, the following topics were discussed: environmental site assessments; geology; bedrock geology; results of environmental site assessments; remediation; and treatment of hydrocarbon impacted soils. It was concluded that the accomplishments made by the industry funded orphan program in Alberta have been rewarding. figs.

    2011-07-01

    In the Athabasca region of Northern Alberta, oil sands activity has raised many concerns over how mining and extracting processes might affect groundwater quality and quantity. The groundwater management framework was developed by Alberta Environment to address these concerns by identifying and managing the potential environmental effects of oil sands activity on groundwater in a science-based manner. This paper develops the framework using risk identification and performance monitoring. The decision-making approach was conducted using decision support tools such as modeling, monitoring and management. Results showed the complexity and variability of groundwater conditions in the Athabasca region and pointed out that knowledge in this area is still developing. This paper presented how the groundwater management framework was developed and pointed out that it will have to be updated as new information arrives.

  7. 3-D-geomechanical-numerical model of the contemporary crustal stress state in the Alberta Basin

    Directory of Open Access Journals (Sweden)

    K. Reiter

    2014-08-01

    Full Text Available In the context of examining the potential usage of safe and sustainable geothermal energy in the Alberta Basin whether in deep sediments or crystalline rock, the understanding of the in-situ stress state is crucial. It is a key challenge to estimate the 3-D stress state at an arbitrary chosen point in the crust, based on sparsely distributed in-situ stress data. To address this challenge, we present a large-scale 3-D geomechanical-numerical model (700 km × 1200 km × 80 km from a large portion of the Alberta Basin, to provide a 3-D continuous quantification of the contemporary stress orientations and stress magnitudes. To calibrate the model, we use a large database of in-situ stress orientation (321 SHmax as well as stress magnitude data (981 SV, 1720 SHmin and 2 (+11 SHmax from the Alberta Basin. To find the best-fit model we vary the material properties and primarily the kinematic boundary conditions of the model. This study focusses in detail on the statistical calibration procedure, because of the large amount of available data, the diversity of data types, and the importance of the order of data tests. The best-fit model provides the total 3-D stress tensor for nearly the whole Alberta Basin and allows estimation of stress orientation and stress magnitudes in advance of any well. First order implications for the well design and configuration of enhanced geothermal systems are revealed. Systematic deviations of the modelled stress from in-situ data are found for stress orientations in the Peace River- and the Bow Island Arch as well as for leak-off-test magnitudes.

    Background: Prospective cohorts have the potential to support multifactorial, health-related research, particularly if they are drawn from the general population, incorporate active and passive follow-up and permission is obtained to allow access by researchers to data repositories. This paper describes Phase I of the Alberta's Tomorrow Project cohort, a broad-based research platform designed to support investigations into factors that influence cancer and chronic disease risk. Methods: Adults aged 35-69 years living in Alberta, Canada, with no previous cancer diagnosis other than nonmelanoma skin cancer were recruited to the project by telephone-based random digit dialling. Participants were enrolled if they returned a Health and Lifestyle Questionnaire. Past year diet and physical activity questionnaires were mailed 3 months after enrolment. Consent was sought for active follow-up and linkage with administrative databases. Depending on enrolment date, participants were invited to complete up to 2 follow-up questionnaires (2004 and 2008). Results: Between 2001 and 2009, 31 072 (39% men) participants (mean age 50.2 [± 9.2] yr) were enrolled and 99% consented to linkage with administrative databases. Participants reported a wide range of educational attainment and household income. Compared with provincial surveillance data from the Canadian Community Health Survey, Alberta's Tomorrow Project participants had higher body mass index, lower prevalence of smoking and similar distribution of chronic health conditions. Follow-up questionnaires were completed by 83% and 72% of participants in 2004 and 2008, respectively. Robust quality control measures resulted in low frequencies of missing data. Interpretation: Alberta's Tomorrow Project provides a robust platform, based on a prospective cohort design, to support research into risk factors for cancer and chronic disease. PMID:27730115

    2009-05-01

    The authors measured the total expenditures for two key sources of social support in Alberta in 2005 for persons with severe and persistent mental illness and compared these expenditures with the total mental health expenditures. Social services and assistance benefit data were from the federal government's Canada Pension Plan-Disability Benefits and from Alberta Services' Assured Income for the Severely Handicapped for beneficiaries with psychiatric diagnoses. These benefits were compared with the total public mental health expenditures in Alberta for budget year 2005-2006. A total of 7,456 adults with certified mental illness conditions received federal disability benefits, and 17,138 received provincial disability and medical benefits. The total for social support (income) benefits was $207 million Canadian compared with $405 million Canadian spent by the provincial government for mental health services for adults under age 65. Social assistance forms a substantial portion of Canadian federal and provincial government support for persons with mental illness. Whenever a government-payer perspective is taken, these costs should be factored into the analysis.

    2014-10-19

    We used an exploratory sequential mixed methods approach to study the association between cultural continuity, self-determination, and diabetes prevalence in First Nations in Alberta, Canada. We conducted a qualitative description where we interviewed 10 Cree and Blackfoot leaders (members of Chief and Council) from across the province to understand cultural continuity, self-determination, and their relationship to health and diabetes, in the Alberta First Nations context. Based on the qualitative findings, we then conducted a cross-sectional analysis using provincial administrative data and publically available data for 31 First Nations communities to quantitatively examine any relationship between cultural continuity and diabetes prevalence. Cultural continuity, or "being who we are", is foundational to health in successful First Nations. Self-determination, or "being a self-sufficient Nation", stems from cultural continuity and is seriously compromised in today's Alberta Cree and Blackfoot Nations. Unfortunately, First Nations are in a continuous struggle with government policy. The intergenerational effects of colonization continue to impact the culture, which undermines the sense of self-determination, and contributes to diabetes and ill health. Crude diabetes prevalence varied dramatically among First Nations with values as low as 1.2% and as high as 18.3%. Those First Nations that appeared to have more cultural continuity (measured by traditional Indigenous language knowledge) had significantly lower diabetes prevalence after adjustment for socio-economic factors (p =0.007). First Nations that have been better able to preserve their culture may be relatively protected from diabetes.

  13. Development, testing and implementation of an emergency services methodology in Alberta.

    Eliasoph, H; Ashdown, C

    1995-01-01

    Alberta was the first province in Canada to mandate reporting of hospital-based emergency services. This reporting is based on a workload measurement system that groups emergency visits into five discreet workload levels/classes driven by ICD-9-CM diagnoses. Other related workload measurement variables are incorporated, including admissions, transfers, maintenance monitoring, nursing and non-nursing patient support activities, trips, staff replacement, and personal fatigue and delay. The methodology used to design the reporting system has been subjected to extensive testing, auditing and refinement. The results of one year of province-wide data collection yielded approximately 1.5 million emergency visits. These data reveal consistent patterns/trends of workload that vary by hospital size and type. Although this information can assist in utilization management efforts to predict and compare workload and staffing levels, the impetus for establishing this system derived from its potential for funding hospital-based emergency services. This would be the first time that such services would be funded on a systemic, system-wide basis whereby hospitals would be reimbursed in relation to workload. This proposed funding system would distribute available funding in a consistent, fair and equitable manner across all hospitals providing a similar set of services, thus achieving one of the key goals of the Alberta Acute Care Funding Plan. Ultimately, this proposed funding methodology would be integrated into a broader Ambulatory Care Funding system currently being developed in Alberta.

    The global migration of physicians has led many international physicians to enter practice in Alberta, Canada. The study was designed to explore the personal side of migration and transition experiences of these international medical graduates (IMGs). A qualitative study using telephone interviews and a semi-structured interview guide was used to interview 19 IMGs who are currently practicing and have held Part V, restricted or temporary practice licenses for less than 7 years. Three major themes were identified. The first was the "push" from their own country of origin and their perception that moving to Alberta would be better for them. Professional opportunities in their home country had been affected by changing policies, lack of infrastructure, and personal/family safety issues culminating in highly stressful work environments. The second was "pull." An improvement in the quality of personal life was associated with geographical, educational, recreational, and spiritual aspects of daily living for participants and their families in their new environment. The third theme was "plant"ie, factors that encouraged them to stay in Alberta. This study demonstrates the continued relevance of push and pull theory in understanding IMG physician migration. Our findings in this study indicate that remaining in place, or "being planted" is conditional on political, social, and economic aspects.

    2017-04-01

    Salmonella is one of the most common enteric pathogens related to foodborne illness. Alberta's Provincial Laboratory for Public Health (ProvLab) provides Outbreak and Surveillance support by performing serotyping. The Check&Trace Salmonella™ (CTS) assay (Check-Points, Netherlands), a commercial DNA microarray system, can determine the serotype designation of a Salmonella isolate with automated interpretation. Here we evaluate 1028 Salmonella isolates of human clinical or environmental sources in Alberta, Canada with the CTS assay. CTS was able to assign a serovar to 98.7% of the most frequently occurring human clinical strains in Alberta (82.5% overall), and 71.7% of isolates which were inconclusive by conventional methods. There was 99.7% concordance in environmental isolates. The CTS database has potential to expand to identify rare serovars. With the anticipated shift to molecular methods for identification, CTS provides an easy transition and demonstrates ease-of-use and reduces the turn-around-time of a reported result significantly compared to classical serotyping.

    2013-08-01

    The most common presentation of chronic disease is multimorbidity. Disease management strategies are similar across most chronic diseases. Given the prevalence of multimorbidity and the commonality in approaches, fragmented single disease management must be replaced with integrated care of the whole person. The Alberta Healthy Living Program, a community-based chronic disease management program, supports adults with, or at risk for, chronic disease to improve their health and well being. Participants gain confidence and skills in how to manage their chronic disease(s) by learning to understand their health condition, make healthy eating choices, exercise safely and cope emotionally. The program includes 3 service pillars: disease-specific and general health patient education, disease-spanning supervised exercise and Better Choices, Better Health(TM) self-management workshops. Services are delivered in the community by an interprofessional team and can be tailored to target specific diverse and vulnerable populations, such as Aboriginal, ethno-cultural and francophone groups and those experiencing homelessness. Programs may be offered as a partnership between Alberta Health Services, primary care and community organizations. Common standards reduce provincial variation in care, yet maintain sufficient flexibility to meet local and diverse needs and achieve equity in care. The model has been implemented successfully in 108 communities across Alberta. This approach is associated with reduced acute care utilization and improved clinical indicators, and achieves efficiencies through an integrated, disease-spanning patient-centred approach.

    To assess potential future impacts on shallow aquifers by leakage of natural gas from unconventional energy resource development it is essential to establish a reliable baseline. Occurrence of methane in shallow groundwater in Alberta between 2006 and 2014 was assessed and was ubiquitous in 186 sampled monitoring wells. Free and dissolved gas sampling and measurement approaches yielded comparable results with low methane concentrations in shallow groundwater, but in 28 samples from 21 wells methane exceeded 10 mg/L in dissolved gas and 300,000 ppmv in free gas. Methane concentrations in free and dissolved gas samples were found to increase with well depth and were especially elevated in groundwater obtained from aquifers containing coal seams and shale units. Carbon isotope ratios of methane averaged − 69.7 ± 11.1‰ (n = 63) in free gas and − 65.6 ± 8.9‰ (n = 26) in dissolved gas. δ{sup 13}C values were not found to vary with well depth or lithology indicating that methane in Alberta groundwater was derived from a similar source. The low δ{sup 13}C values in concert with average δ{sup 2}H{sub CH4} values of − 289 ± 44‰ (n = 45) suggest that most methane was of biogenic origin predominantly generated via CO{sub 2} reduction. This interpretation is confirmed by dryness parameters typically > 500 due to only small amounts of ethane and a lack of propane in most samples. Comparison with mud gas profile carbon isotope data revealed that methane in the investigated shallow groundwater in Alberta is isotopically similar to hydrocarbon gases found in 100–250 meter depths in the WCSB and is currently not sourced from thermogenic hydrocarbon occurrences in deeper portions of the basin. The chemical and isotopic data for methane gas samples obtained from Alberta groundwater provide an excellent baseline against which potential future impact of deeper stray gases on shallow aquifers can be assessed. - Highlights: • Analysis of gas geochemical data from 186

    The extraction and processing of bitumen from the oilsands of Northern Alberta requires very large amounts of heat that is obtained by burning natural gas. At current levels, the gas used represents 6% of Canada's natural gas production. Geothermal energy could potentially provide this heat, thereby reducing both the financial costs and environmental impact of the oilsands industry. The Helmholtz Alberta Initiative is evaluating this application of geothermal energy through an integrated program of geology, geophysics, reservoir simulation and calculations of the cost benefit. A first stage in this evaluation is refining estimates of subsurface temperature beneath Northern Alberta. This has involved three stages: (1) Corrected industrial thermal data have been used to revise estimates of the upper crustal temperatures beneath the oilsands regions in Alberta. The geothermal gradient map produced using heat flow and thermal conductivity for the entire Phanerozoic column suggests that the overall gradient of the entire column is less than the gradients calculated directly from industry measurements. (2) Paleoclimatic corrections must be applied , since this region has experienced a significant increase in surface temperatures since the end of the last ice age causing a perturbation of shallow heat flow. For this reason, estimates of geothermal gradient based on shallow data are not necessarily characteristic of the whole sedimentary column and can lead to errors in temperature prediction at depth. (3) Improved measurements have been made of the thermal conductivity of the crystalline basement rocks (average = 2.9±0.8 W/m K). Thermal conductivity exhibits significant spatial variability and to a large degree controls the temperature conditions in the Precambrian crystalline basement rocks and its heat content at given heat flow-heat generation. When these steps are used to calculate subsurface temperatures, it can be shown that the temperatures required for geothermal

To introduce an alternative, the ?learning conference,? that involves delegates in fun and productive learning processes. Design....../methodology/approach: A typical full-day conference is analyzed. It has six hours of podium talk and twenty-five minutes for delegates to become involved. What model of learning can possibly lie behind this?

    We investigated changes to precipitation and temperature of Alberta for historical and future periods. First, the Mann-Kendall test and Sen's slope were used to test for historical trends and trend magnitudes from the climate data of Alberta, respectively. Second, the Special Report on Emissions Scenarios (SRES) (A1B, A2, and B1) of CMIP3 (Phase 3 of Coupled Model Intercomparison Project), projected by seven general circulation models (GCM) of the Intergovernmental Panel on Climate Change (IPCC) for three 30 years periods (2020s, 2050s, and 2080s), were used to evaluate the potential impact of climate change on precipitation and temperature of Alberta. Third, trends of projected precipitation and temperature were investigated, and differences between historical versus projected trends were estimated. Using the 50-km resolution dataset from CANGRD (Canadian Grid Climate Data), we found that Alberta had become warmer and somewhat drier for the past 112 years (1900-2011), especially in central and southern Alberta. For observed precipitation, upward trends mainly occurred in northern Alberta and at the leeward side of Canadian Rocky Mountains. However, only about 13 to 22 % of observed precipitation showed statistically significant increasing trends at 5 % significant level. Most observed temperature showed significant increasing trends, up to 0.05 °C/year in DJF (December, January, and February) in northern Alberta. GCMs' SRES projections indicated that seasonal precipitation of Alberta could change from -25 to 36 %, while the temperature would increase from 2020s to 2080s, with the largest increase (6.8 °C) in DJF. In all 21 GCM-SRES cases considered, precipitation in both DJF and MAM (March, April, and May) is projected to increase, while temperature is consistently projected to increase in all seasons, which generally agree with the trends of historical precipitation and temperature. The SRES A1B scenario of CCSM3 might project more realistic future climate for

    With a decade of experience available, there is a period of sufficient duration to allow a broad assessment of the Canada-US Free Trade Agreement's (FTA) impact on the Alberta economy. The disposition of three classes of exports - energy, agricultural and non-energy/non-agricultural to individual US states is examined. Besides creating a new range of market opportunities for Alberta companies, the FTA helped diversification within the energy industry by guaranteeing US market access for natural gas producers. The major sections of the report deal with: the FTA experience from 1988 to 1998, exports, overview of the Alberta export sector, employment variability in Alberta, inward foreign direct investment since the FTA: data and implications and an assessment of the impact of tariff reductions under the FTA. Alberta's international export sector increased over this period in size and in relative importance. Goods exported to foreign countries as a share of the provincial Gross Domestic Product rose from a 1/4 in 1988 to 1/3 in 1998. This absolute and relative growth in the export sector coincided with the rise in the importance of shipments to the U.S. market.

  7. Deep 3-D seismic reflection imaging of Precambrian sills in the crystalline crust of Alberta, Canada

    2005-07-01

    Using deep 3-D seismic reflection datasets collected by the Canadian petroleum exploration industry in southwestern and northwestern Alberta, the Head-Smashed-In and Winagami Precambrian sill complexes within the crystalline upper crust, previously identified on Lithoprobe 2-D multichannel reflection lines, are investigated to determine their 3-D geometries and reflective characteristics. During seismic processing of the dataset in southwestern Alberta, a recently developed wavelet-based method, Physical Wavelet Frame Denoising, is applied and shown to successfully suppress ground roll contamination while preserving low frequency signals from deeper structures. A new 3-D empirical trace interpolation scheme, DSInt, is developed to address the problem of spatial aliasing associated with 3-D data acquisition. Results from applying the algorithm to both datasets are comparable to available interpolation codes while allowing for greater flexibility in the handling of irregular acquisition geometries and interpolated trace headers. Evidence of the Head-Smashed-In reflector in southwestern Alberta is obtained using a dataset acquired to 8 s TWTT (approx. 24 km depth). From locally coherent, discontinuous pockets of basement reflectivity, the dataset appears to image the tapering western edge of the deep reflections imaged by Lithoprobe. A statistical approach of tracking reflectivity is developed and applied to obtain the spatial and temporal distribution of reflections. Simple 1-D forward modelling results reveal that the brightest reflections likely arise from a 50 to 150 m thick body of high density/high velocity material although variations in the amplitudes and lateral distribution of the reflections indicate that the thickness of the sills is laterally variable. Thus, the results are consistent with imaging the tapering edge of the sill complex. Clear evidence of the Winagami reflection sequence in northwestern Alberta, emerges from the second dataset acquired to 5

    Alberta, Canada, is an important global producer of petroleum resources. In association with this production, large amounts of gas (1.14 billion m3 in 2008) are flared or vented. Although the amount of flaring and venting has been measurably reduced since 2002, data from 2005 reveal sharp increases in venting, which have important implications in terms of resource conservation and greenhouse gas emissions (which exceeded 8 million tonnes of carbon dioxide equivalent in 2008). With use of extensive monthly production data for 18,203 active batteries spanning the years 2002-2008 obtained in close cooperation with the Alberta Energy Resources Conservation Board, a detailed analysis has been completed to examine activity patterns of flaring and venting and reasons behind these trends in the Alberta upstream oil and gas industry. In any given year, approximately 6000 batteries reported flaring and/or venting, but the distribution of volumes flared and vented at individual sites was highly skewed, such that small numbers of sites handled large fractions of the total gas flaring and venting in the Province. Examination of month-to-month volume variability at individual sites, cast in terms of a nominal turndown ratio that would be required for a compressor to capture that gas and direct it into a pipeline, further revealed that volumes at a majority of sites were reasonably stable and there was no evidence that larger or more stable sites had been preferentially reduced, leaving potential barriers to future mitigation. Through linking of geospatial data with production data coupled with additional statistical analysis, the 31.2% increase in venting volumes since 2005 was revealed to be predominantly associated with increased production of heavier oils and bitumen in the Lloydminster region of the Province. Overall, the data suggest that quite significant reductions in flaring and venting could be realized by seeking mitigation solutions for only the largest batteries in

  11. A Hybrid Ground-Motion Prediction Equation for Earthquakes in Western Alberta

    2015-12-01

    Estimation of ground-motion amplitudes that may be produced by future earthquakes constitutes the foundation of seismic hazard assessment and earthquake-resistant structural design. This is typically done by using a prediction equation that quantifies amplitudes as a function of key seismological variables such as magnitude, distance and site condition. In this study, we develop a hybrid empirical prediction equation for earthquakes in western Alberta, where evaluation of seismic hazard associated with induced seismicity is of particular interest. We use peak ground motions and response spectra from recorded seismic events to model the regional source and attenuation attributes. The available empirical data is limited in the magnitude range of engineering interest (M>4). Therefore, we combine empirical data with a simulation-based model in order to obtain seismologically informed predictions for moderate-to-large magnitude events. The methodology is two-fold. First, we investigate the shape of geometrical spreading in Alberta. We supplement the seismic data with ground motions obtained from mining/quarry blasts, in order to gain insights into the regional attenuation over a wide distance range. A comparison of ground-motion amplitudes for earthquakes and mining/quarry blasts show that both event types decay at similar rates with distance and demonstrate a significant Moho-bounce effect. In the second stage, we calibrate the source and attenuation parameters of a simulation-based prediction equation to match the available amplitude data from seismic events. We model the geometrical spreading using a trilinear function with attenuation rates obtained from the first stage, and calculate coefficients of anelastic attenuation and site amplification via regression analysis. This provides a hybrid ground-motion prediction equation that is calibrated for observed motions in western Alberta and is applicable to moderate-to-large magnitude events.

  12. Precious grasses : Alberta Research Council releases new native species for reclamation

    2006-03-15

    The Alberta Research Council has released 6 new varieties of native plant species suitable for reclamation in Alberta's Parkland region, which is characterized by sandy soils. The Parkland stretches for 37,000 kilometres and is the most densely populated of the province's 6 ecoregions. Because of farming, grazing, oil and gas development and recreation, only 5 per cent of the area remains undisturbed. It was anticipated that the native grasses will help disturbed sites eventually resemble their original state. Varieties included: Aspen Milk Vetch; Centennial Canada Wild Rye; Hillbilly Nodding Brome; Butte Rocky Mountain Fescue; Porter Indian Rice Grass; and Metisko Awned Wheatgrass. The varieties were evaluated for their ability to provide rapid cover and their ability to compete with invading weeds, as well as their ability to allow recruitment of other native species. Multi-environmental testing trials were established to evaluate the species' seed production potential. Seeds were tested for germination in species-specific growth chambers, grown in greenhouses and then taken to an agricultural setting where data on forage density; ground cover; vigour; and biomass were then recorded. The species have also been targeted to ensure that the oil and gas industry has better options for reclaiming disturbed sites. In addition to their ability to combat threats from invasive species, the native plant species have been investigated for their ability to remediate hydrocarbon and salt contaminants and sequester carbon dioxide. Details of Alberta's current reclamation criteria for wellsites and associated facilities were also presented. 4 figs.

    Balsam poplar seeds are short-lived and require moist seedbeds soon after they are released to germinate. In addition to sexual reproduction, balsam poplar stands can regenerate clonally by root suckering. The origin of stands will in turn affect their genetic structure and root system architecture, which are poorly understood for upland forest stands. Three stands were hydraulically excavated in Quebec (moist) and Alberta (dry) to determine the origin of trees and to characterize root systems with respect to presence of parental roots and root grafts connections. Clones were identified using single-nucleotide polymorphism (SNPs), and all stems, roots and root grafts were aged using dendrochronology techniques. All 82 excavated trees were of sucker origin, and four of the six stands contained a single clone. Parental root connections were found between 22% and 25% of excavated trees, and 53% and 48% of trees were linked with a root graft between the same or different clones, in Alberta and Quebec, respectively. Mean distance between trees connected by parental root was significantly lower than the distance between unconnected trees (0.47 ± 0.25 m vs. 3.14 ± 0.15 m and 1.55 ± 0.27 m vs. 4.25 ± 0.13 m) in Alberta and in Quebec, respectively. The excavations also revealed many dead stumps with live roots, maintained through root connections with live trees. This research highlights that balsam poplar growing in upland stands is a clonal species that can maintain relatively high genotypic diversity, with frequent root connections between trees at maturity. Maintaining an extensive root system through root connections increases the chances of a clone surviving when the above ground tree is dead and may also enhance the resilience of balsam poplar stands after disturbance.

    The economic impact of taxes, royalties and government fiscal policy tools on conventional crude oil supply in Alberta was examined. A dynamic economic model of Alberta`s conventional petroleum industry was developed and used to evaluate the quantitative impacts of government fiscal policies on exploration and extraction of conventional crude oil in the province. It was determined that taxes and royalties can shorten the life of the industry, reduce activity level, reduce ultimate recovery of conventional crude oil, render more of the established reserves sub-economic and create social welfare loss. It was also revealed that compared to provincial corporate income tax and crown royalties, federal corporate income tax has a larger adverse effect on the performance of the industry in terms of creating higher dead-weight loss and shortening the life of the industry.

  16. A process-based agricultural model for the irrigated agriculture sector in Alberta, Canada

    Ammar, M. E.; Davies, E. G.

    2015-12-01

    Connections between land and water, irrigation, agricultural productivity and profitability, policy alternatives, and climate change and variability are complex, poorly understood, and unpredictable. Policy assessment for agriculture presents a large potential for development of broad-based simulation models that can aid assessment and quantification of policy alternatives over longer temporal scales. The Canadian irrigated agriculture sector is concentrated in Alberta, where it represents two thirds of the irrigated land-base in Canada and is the largest consumer of surface water. Despite interest in irrigation expansion, its potential in Alberta is uncertain given a constrained water supply, significant social and economic development and increasing demands for both land and water, and climate change. This paper therefore introduces a system dynamics model as a decision support tool to provide insights into irrigation expansion in Alberta, and into trade-offs and risks associated with that expansion. It is intended to be used by a wide variety of users including researchers, policy analysts and planners, and irrigation managers. A process-based cropping system approach is at the core of the model and uses a water-driven crop growth mechanism described by AquaCrop. The tool goes beyond a representation of crop phenology and cropping systems by permitting assessment and quantification of the broader, long-term consequences of agricultural policies for Alberta's irrigation sector. It also encourages collaboration and provides a degree of transparency that gives confidence in simulation results. The paper focuses on the agricultural component of the systems model, describing the process involved; soil water and nutrients balance, crop growth, and water, temperature, salinity, and nutrients stresses, and how other disciplines can be integrated to account for the effects of interactions and feedbacks in the whole system. In later stages, other components such as

    Scholarship on Alberta's Sexual Sterilization Act (1928-1972) has focused on the high-level politics behind the legislation, its main administrative body, the Eugenics Board, and its legal legacy, overlooking the largely female-dominated professions that were responsible for operating the program outside of the provincial mental health institutions. This paper investigates the relationship between eugenics and the professions of teaching, public health nursing, and social work. It argues that the Canadian mental hygiene and eugenics movements, which were fundamentally connected, provided these professions with an opportunity to maintain and extend their professional authority.

    A strategy for implementing telemedicine throughout Alberta was developed. The model was based on a comprehensive evaluation of the four clinical specialties chosen as representative telemedicine services--radiology, psychiatry, emergency services and continuing education. The goals of the telemedicine network were to improve access to health services, provide support for rural health-care providers and increase the efficiency of specialized services. The findings showed that the success factors in a national telemedicine programme depend on a clear organizational structure, with appropriate technical standards and support.

  4. Achieving conservation when opportunity costs are high: optimizing reserve design in Alberta's oil sands region.

    Richard R Schneider

    Full Text Available Recent studies have shown that conservation gains can be achieved when the spatial distributions of biological benefits and economic costs are incorporated in the conservation planning process. Using Alberta, Canada, as a case study we apply these techniques in the context of coarse-filter reserve design. Because targets for ecosystem representation and other coarse-filter design elements are difficult to define objectively we use a trade-off analysis to systematically explore the relationship between conservation targets and economic opportunity costs. We use the Marxan conservation planning software to generate reserve designs at each level of conservation target to ensure that our quantification of conservation and economic outcomes represents the optimal allocation of resources in each case. Opportunity cost is most affected by the ecological representation target and this relationship is nonlinear. Although petroleum resources are present throughout most of Alberta, and include highly valuable oil sands deposits, our analysis indicates that over 30% of public lands could be protected while maintaining access to more than 97% of the value of the region's resources. Our case study demonstrates that optimal resource allocation can be usefully employed to support strategic decision making in the context of land-use planning, even when conservation targets are not well defined.

  6. Effects of industrial noise on wildlife : issues and challenges in Alberta

    Burke, D.; Lapka, S. [Alberta Energy and Utilities Board, Calgary, AB (Canada)

    2007-07-01

    The effects of noise from industrial activities on wildlife was examined with particular reference to the potential impacts of noise on caribou and grizzly bears from the Mackenzie Gas pipeline project. In Alberta, environmental noise requirements for oil and gas production facilities are outlined in the Alberta Energy and Utilities Board (EUB) Noise Control Directive 038. The requirements provide protection for human receptors, but not for wildlife. In order to ensure accurate assessments of the effects that industrial noise is having on wildlife, appropriate study methods must be developed to identify, quantify, and assess wildlife responses to noise. Without this knowledge, noise level thresholds for wildlife species cannot be established. A literature review was presented to demonstrate the range of published information on noise effects on wildlife and to highlight information that is relevant for the development of noise criteria for wildlife. It was concluded that wildlife noise thresholds are unknown, evidence for habituation to industrial facilities is limited, and long-term effects are generally unknown. Preliminary studies do not show any clear indication that observed reactions of wild animals are in response to noise. As such, development of regulatory criteria for wildlife noise control is not recommended at this time. The EUB will continue to keep up to date in wildlife related noise issues and will maintain the existing philosophy to limit noise to 5dB above ambient and to control dBA levels at 1500 m from facility fence lines. 57 refs., 1 fig.

    To evaluate a possible association between neighbourhood socio-economic status and spontaneous premature birth in Alberta births. The study design was a retrospective cohort of all births in Alberta for the years 2001 and 2006. The primary outcome was spontaneous preterm birth at <37 weeks gestation. Neighbourhood socio-economic status was measured by the Pampalon Material Deprivation Index for each Statistics Canada census dissemination area. Births were linked to dissemination area using maternal postal codes. The analysis comprised 73,585 births, in which the rate of spontaneous preterm delivery at <37 weeks was 5.3%. The rates of spontaneous preterm delivery for each neighbourhood socio-economic category ranged from 4.9% (95% CI 4.5%-5.2%) in the highest category to 6.3% (95% CI 6.0%-6.7%) in the lowest (p<0.001). After controlling for smoking, parity, maternal age and year, we found that women living in the highest socio-economic status neighbourhoods had an adjusted spontaneous preterm birth rate of 5.1% (95% CI 4.7%-5.5%) compared to 6.0% (95% CI 5.6%-6.4%) for women living in the lowest (p=0.003). This study documented a modest increase in the risk of spontaneous preterm birth with low socio-economic status. The possibility of confounding bias cannot be ruled out.

    The electric industry deregulation in Alberta is reviewed by an energy management consultant. He concludes that while the concept of deregulation was correct and laudable, especially from the point of view of industrial clients for whom deregulation was expected to create a significant potential for cogeneration, open access to the transmission grid and the wholesale market to sell surplus generation, there have been too many shortcomings initially for the system to operate as planned. To mention only the major faults: there was no wholesale market where surplus generation could be traded; there was no obligation on the regulated distribution companies to contract for capacity to hedge their captive customers; access to wholesale market was delayed by incumbents since they had market power without price risk; incumbents allowed to increase prices to benefit their unregulated production; there was insufficient consumer price protection; almost all new generation developed was done in conjunction with an incumbent, i.e. there were no significant new entrants into the Alberta market. The reviewer concluded that the government's reluctance to force generation deregulation resulted in lost value; lack of consumer protection led to $1 billion cost from the year 2000 price spikes; government response was late and damaging; retail competition continues to remain illusive; benefits from distributed generation may be lost with transmission expansions; and benefits from increased exports will likely not flow to consumers.

    This study evaluated the prevalence of dental trauma for patients attending the emergency dental clinic at the University of Alberta Hospital between 2006-2009. Patients' examination and treatment charts were reviewed. Total number of patients' charts was 1893.The prevalence of different types of trauma was 6.4 % of the total cases (117 patients). Trauma cases were identified according to Ellis classification and as modified by Holland et al., 1988. Logistic statistical model showed that 21.7% were Ellis class I trauma, 16.7% were Ellis class II trauma, and 6.7% were Ellis class III. In addition, 11.7 % presented with avulsion, 7.5 % presented with dentoalveolar fracture and 7.5% presented with sublaxation. Also, 17.55 % presented with tooth displacement within the alveolar bone, 3.3 % presented with crown fracture with no pulp involvement, 4.16 % presented with crown fracture with pulp involvement and 3.3 % presented with root fracture. In conclusion, the general prevalence of dentoalveolar trauma in patients attending the emergency clinic at the University of Alberta is less than other reported percentages in Canada or other countries.

  10. Wetland habitat selection by woodland caribou as characterized using the Alberta Wetland Inventory

    2011-04-01

    Full Text Available We examined habitat selection by woodland caribou (Rangifer tarandus caribou in northwestern Alberta based on a wetland classification system developed for the Alberta Vegetation Inventory. Our two objectives were to describe caribou habitat use, and to assess the utility of the wetland classification system in land-use planning on caribou range. We used a geographical information system to overlay the locations of radio-collared caribou on the habitat map. Using a "moving-window" analysis of habitat availability, we examined patterns of habitat selection by 16 individual female caribou during five seasons annually over two years. We did not detect significant differences in habitat selection patterns among seasons. Caribou showed significant preferences for both bogs and fens with low to moderate tree cover relative to marshes, uplands, heavily forested wetlands, water, and areas of human use. The wetland classification system appears to have value for broad-scale planning of industrial activity on caribou range. More-detailed descriptions of vegetation, especially understory species, are required to refine this system for operational-level forest harvest planning.

  11. Energy to the masses : a blueprint for competition in Alberta's retail energy markets

    Topp, L. [Direct Energy Marketing Ltd., Calgary, AB (Canada)

    2004-07-01

    This paper presents a framework for competition in Alberta's retail energy market and its influence on Direct Energy Marketing Limited . The main factors for successful retail energy competition were identified as being a level playing field for all retailers; a stable and committed regulatory framework; customer education; brand trust and visibility; regulated pricing which reflects market conditions; customer service and billing; unrestricted customer choice; and, conformity between electricity and gas markets. Direct Energy is a wholly owned subsidiary of British-based Centrica plc, one of the top 30 companies in the United Kingdom in terms of market capitalization. It was created during Britain's regulatory reform of the energy industry and operates through 4 retail brand units. Centrica entered the North American market in 2000 when it acquired Direct Energy Marketing Limited which supplies energy and services to half of the households in Ontario. Direct Energy is expected to increase its customer base with the pending closure of ATCO Gas and ATCO Electric in Alberta, making it Canada's largest provider of retail energy services. In a competitive energy market, retailers can offer a wider range of products than energy alone. Cost-to services can be reduced by offering services such as heating, ventilation and air conditioning.

  12. Habitat associations with counts of declining Western Grebes in Alberta, Canada

    Full Text Available During the past several decades, numbers of Western Grebes (Aechmophorus occidentalis have declined throughout their breeding and wintering ranges in North America. We estimated Western Grebe abundance and documented habitat factors between 2007 and 2009 from 43 lakes in Alberta, Canada where Western Grebes historically have occurred, to (1 compare Western Grebe abundance with the relative probability of persistence, and (2 identify habitat correlates of grebe abundance. The relative probability of Western Grebe persistence was correlated with abundance in the study area, although only 19% of the variation in persistence probability was explained by abundance. Western Grebe abundance was positively correlated with the shoreline extent of emergent bulrush (Scirpus lacustris, which is consistent with past studies and underlies the importance of protecting emergent vegetation in efforts to conserve Western Grebes. Grebe abundance also was positively correlated with a longer shoreline perimeter, but was inversely correlated with the amount of forested backshore, which occurred on lakes primarily at the northern margins of Western Grebe range. The amount of backshore development was positively associated with Western Grebe abundance, which might reflect a preference for similar lake characteristics by humans and grebes. These relationships are important to consider in the context of implementing and managing recovery of the Western Grebe in Alberta.

    Full Text Available Abstract Introduction In common with other jurisdictions, Alberta faces challenges in ensuring a balance in health worker supply and demand. As the provider organization with province-wide responsibility, Alberta Health Services needed to develop a forecasting tool to inform its position on key workforce parameters, in the first instance focused on modeling the situation for Registered Nurses, Licensed Practical Nurses and health care aides. This case study describes the development of the model, highlighting the choices involved in model development. Case description A workforce planning model was developed to test the effect of different assumptions (for instance about vacancy rates or retirement and different policy choices (for example about the size of intakes into universities and colleges, different composition of the workforce. This case study describes the choices involved in designing the model. The workforce planning model was used as part of a consultation process and to develop six scenarios (based on different policy choices. Discussion and evaluation The model outputs highlighted the problems with continuation of current workforce strategies and the impact of key policy choices on workforce parameters. Conclusions Models which allow for transparency of the underlying assumptions, and the ability to assess the sensitivity of assumptions and the impact of policy choices are required for effective workforce planning.

    Alberta's oil sands are among the world's largest deposits of crude oil, and more than 80% of it is too deep to mine, so unconventional in-situ methods are used for extraction. Most in situ extraction techniques, such as Steam-Assisted Gravity Drainage (SAGD), use steam injection to reduce the viscosity of the bitumen, allowing it to flow into wells to be pumped to the surface. As part of the oil sands safety and environmental monitoring program, the energy regulator uses satellite radar to monitor surface deformation associated with in-situ oil extraction. The dense vegetation and sparse infrastructure in the boreal forest of northern Alberta make InSAR monitoring a challenge; however, we have found that surface heave associated with steam injection can be detected using traditional differential InSAR. Infrastructure and installed corner reflectors also allow us to use persistent scatterer methods to obtain time histories of deformation at individual sites. We have collected and processed several tracks of RADARSAT-2 data over a broad area of the oil sands, and have detected surface deformation signals of approximately 2-3 cm per year, with time series that correlate strongly with monthly SAGD steam injection volumes.

    2008-07-01

    Heads of 64 white-tailed deer (Odocoileus virginianus) fawns, harvested in the vicinity of Magrath, Alberta, Canada, (49 degrees 24'782''N, 112 degrees 52'113''W) were examined for the presence of nasal bots and lice. The deer were collected between 8-30 January 2004 as part of a government-approved herd reduction protocol. The entire surface of each head was scanned visually for the presence of lice. Each head was split longitudinally, and the nasal passages, sinuses, and ethmoid region were washed for recovery of nasal bots. First instar Cephenemyia spp. were recovered from 17 heads (27%). Intensity of infestation ranged from 1-18 larvae (mean intensity 4.8). Among fawns, there were no significant differences in prevalence or mean intensity between the sexes. Two species of nasal bots were identified. Smaller larvae, tentatively identified as C. jellisoni, were present in 16 of 17 infested deer while larger specimens, tentatively identified as C. phobifera, were found in four deer; and in three of the four it co-occurred with C. jellisoni. The presence of C. phobifera in Alberta would represent a range extension for this species, which has not been known to occur west of North Dakota. Thirty-one fawns (48%) were infested with the sucking louse Solenopotes ferrisi. One infested fawn also had one specimen of the chewing louse, Tricholiopeurus lipeuroides.

  16. The impact of roads on the demography of grizzly bears in Alberta.

    Boulanger, John; Stenhouse, Gordon B

    2014-01-01

    One of the principal factors that have reduced grizzly bear populations has been the creation of human access into grizzly bear habitat by roads built for resource extraction. Past studies have documented mortality and distributional changes of bears relative to roads but none have attempted to estimate the direct demographic impact of roads in terms of both survival rates, reproductive rates, and the interaction of reproductive state of female bears with survival rate. We applied a combination of survival and reproductive models to estimate demographic parameters for threatened grizzly bear populations in Alberta. Instead of attempting to estimate mean trend we explored factors which caused biological and spatial variation in population trend. We found that sex and age class survival was related to road density with subadult bears being most vulnerable to road-based mortality. A multi-state reproduction model found that females accompanied by cubs of the year and/or yearling cubs had lower survival rates compared to females with two year olds or no cubs. A demographic model found strong spatial gradients in population trend based upon road density. Threshold road densities needed to ensure population stability were estimated to further refine targets for population recovery of grizzly bears in Alberta. Models that considered lowered survival of females with dependant offspring resulted in lower road density thresholds to ensure stable bear populations. Our results demonstrate likely spatial variation in population trend and provide an example how demographic analysis can be used to refine and direct conservation measures for threatened species.

  3. The Role of Sustainability Resources of Large Greenhouse Gas Emitters: The Case of Corporations in Alberta, Canada

    Directory of Open Access Journals (Sweden)

    Marwa Hannouf

    2017-01-01

    Full Text Available With the global challenge of climate change, it becomes crucial to understand the factors that can guide carbon intensive companies to comply with environmental regulations through significant reductions in greenhouse gas (GHG emissions. Using the natural-resource-based view, the argument in this paper is that focusing on sustainability-driven resources by companies is a way to meet environmental compliance and reduce GHG emissions while gaining differential competitive benefits. A specific analysis on Alberta case has discussed large GHG emitters’ environmental compliance mechanisms in the context of their sustainability resources. The aim is examining if large GHG emitters in Alberta related to corporations having sustainability resources are complying with the Specified Gas Emitters Regulation (SGER reduction requirement through cleaner-production driven internal mechanisms. The paper examines the existence of the sustainability resources in the reporting companies related to large GHG emitters responsible for 86% of total GHG reported by facilities with emissions above the threshold of 100 kilotonnes of GHG per year under SGER in Alberta. Corporations are found not using their sustainability resource potential to achieve internal reductions in GHG emissions throughout their facilities. Thus, some recommendations are presented for Alberta case as well as for environmental regulations in other jurisdictions that can potentially help policy makers improve their climate change regulations and achieve their global targets and enable companies to gain competitive advantage while meeting GHG reduction compliance.

  7. Is There a Future for Nuclear Power? Wind and Emission Reduction Targets in Fossil-Fuel Alberta.

    Science.gov (United States)

    van Kooten, G Cornelis; Duan, Jun; Lynch, Rachel

    2016-01-01

    This paper explores the viability of relying on wind power to replace upwards of 60% of electricity generation in Alberta that would be lost if coal-fired generation is phased out. Using hourly wind data from 17 locations across Alberta, we are able to simulate the potential wind power output available to the Alberta grid when modern, 3.5 MW-capacity wind turbines are spread across the province. Using wind regimes for the years 2006 through 2015, we find that available wind power is less than 60% of installed capacity 98% of the time, and below 30% of capacity 74% of the time. There is only a small amount of correlation between wind speeds at different locations, but yet it remains necessary to rely on fossil fuel generation. Then, based on the results from a grid allocation model, we find that CO2 emissions can be reduced by about 30%, but only through a combination of investment in wind energy and reliance on purchases of hydropower from British Columbia. Only if nuclear energy is permitted into the generation mix would Alberta be able to meet its CO2-emissions reduction target in the electricity sector. With nuclear power, emissions can be reduced by upwards of 85%.

    The cooperation between the Alberta Government and the Trucking Industry to enhance highway safety and to protect the highway infrastructure was discussed. The Partners in Compliance (PIC) program, which was launched in 1995, is a voluntary motor carrier safety and compliance program. The program provides rewards for positive actions and commitments; it also provides a means to focus on the less compliant carriers. A total of 247 carriers have expressed an interest in the program; 39 carriers with 3,281 units applied to PIC to date. Twenty-four carriers were approved for immediate membership, six were denied and seven are making changes before plates will be issued. Carrier performance is monitored within the following eight areas: (1) safety and driver qualifications, (2) reportable collision data and analysis, (3) equipment inspection and repairs, (4) drivers` hours of service, (5) dangerous goods, (6) vehicle weights and dimensions, (7) fuel tax compliance, and (8) prorate licensing compliance. Based on a review of the program to July 1997 by an independent consultant, the program was considered to be a viable concept and its continuation recommended. Interest in similar programs have been expressed by several other provinces.

    Development of unconventional energy resources such as shale gas and coalbed methane has generated some public concern with regard to the protection of groundwater and surface water resources from leakage of stray gas from the deep subsurface. In terms of environmental impact to and risk assessment of shallow groundwater resources, the ultimate challenge is to distinguish: (a) natural in-situ production of biogenic methane, (b) biogenic or thermogenic methane migration into shallow aquifers due to natural causes, and (c) thermogenic methane migration from deep sources due to human activities associated with the exploitation of conventional or unconventional oil and gas resources. We have conducted a NSERC-ANR co-funded baseline study investigating the occurrence of methane in shallow groundwater of Alberta (Canada), a province with a long record of conventional and unconventional hydrocarbon exploration. Our objective was to assess the occurrence and sources of methane in shallow groundwaters and to also characterize the hydrochemical environment in which the methane was formed or transformed through redox processes. Ultimately our aim was to determine whether methane was formed in-situ or whether it migrated from deeper formations into shallow aquifers. Combining hydrochemical and dissolved and free geochemical gas data from 372 groundwater samples obtained from 186 monitoring wells of the provincial groundwater observation well network (GOWN) in Alberta, it was found that methane is ubiquitous in groundwater in Alberta and is predominantly of biogenic origin. The highest concentrations of dissolved biogenic methane (> 0.01 mM or > 0.2 mg/L), characterized by δ13CCH4 values gas concentrations and a wide range of δ13CCH4 values in baseline groundwater samples, no conclusive evidence was found for deep thermogenic gas that had migrated in significant amounts into shallow aquifers either naturally or via anthropogenically induced pathways. This study shows that the

  10. From waste molecules to consumer products : upgrader and refinery off-gases processing on the rise in Alberta

    Bentein, J.

    2010-10-15

    Only two companies process off-gases from bitumen upgraders in Alberta: Williams Energy Canada and Aux Sable Canada LP. Their projects, one at the Suncor plant north of Fort McMurray and the other at the Scotford complex near Edmonton, are designed to convert the streams into value-added petrochemical and fuel feedstock. In 2002, Williams built a cryogenic liquids extraction unit at the Suncor plant and a fractioning and distribution facility near Redwater, Alberta, which processes off-gases into liquid propane, propylene, condensates, butane, and butylenes. An expansion to the Redwater processing plant will allow for the upgrading of butane and butylene components as well as octane. Williams wants to build extraction units at two upgraders near Fort McMurray and is working with the Alberta Government to attract a petrochemical plant to Alberta that can process propylene, which must be exported at present. Aux Sable will process off-gases to produce hydrogen, ethane, and a propane-plus mix. Processing off-gases substantially reduces carbon dioxide and sulfur dioxide emissions from upgraders. Off-gas has the potential to be a new feedstock supply for the petrochemical industry in Alberta. The volumes processed by Williams are olephenic, whereas the volumes processed by Aux Sable are paraffinic, but both companies take molecules that would otherwise become atmospheric carbon dioxide and turn them into plastic for consumer goods. The off-gas projects are being driven by market forces without government incentives. Low natural gas prices have made it economical for upgraders to use more gas and sell off-gases for value-added use. 1 fig.

Pre- and post-conference surveys revealed that while financial support played a significant role in educators' ability to participate, they were drawn to the conference by the promise to learn substantive issues related to, in this case, performance assessment—what it means, how to implement it, and how to address community concerns. In spite of the conference's utility as a means to increase awareness of critical issues and to facilitate formal and informal learning, well conceived linkages to transfer new knowledge to the school and classroom were lacking.

    The 3rd annual DGVS Spring Conference of the German Society for Gastroenterology (Deutsche Gesellschaft für Verdauungs- und Stoffwechselkrankheiten) was held at the Seminaris Campus Hotel in Berlin, Germany, on 8-9 May, 2009. The conference was organized by Roland Schmid and Matthias Ebert from the Technical University of Munich, Germany. The central theme of the meeting was 'translational gastrointestinal oncology: towards personalized medicine and individualized therapy'. The conference covered talks on markers for diagnosis, screening and surveillance of colorectal cancer, targets for molecular therapy, response prediction in clinical oncology, development and integration of molecular imaging in gastrointestinal oncology and translational research in clinical trial design. Owing to the broad array of topics and limitations of space, this article will focus on biomarkers, response prediction and the integration of biomarkers into clinical trials. Presentations mentioned in this summary were given by Matthias Ebert (Technical University of Munich, Germany), Esmeralda Heiden (Epigenomics, Berlin, Germany), Frank Kolligs (University of Munich, Germany), Florian Lordick (University of Heidelberg, Germany), Hans Jorgen Nielsen (University of Copenhagen, Denmark), Anke Reinacher-Schick (University of Bochum, Germany), Christoph Röcken (University of Berlin, Germany), Wolff Schmiegel (University of Bochum, Germany) and Thomas Seufferlein (University of Halle, Germany).

    Full Text Available In this article I will review four papers presented at the British Psychological Society Annual Conference held this year in London held over a 3 day period. The Conference included a variety of scientific presentations and discussions through symposia, roundtable discussions, single papers and poster sessions. Although numerous papers took an experimental approach, few applied any type of qualitative methodology. The topics covered within the different psychological disciplines spanned from early childhood through old age; I have chosen four papers that covered a life course perspective and took into consideration clinical issues as well. The first paper discusses a grounded theory approach used to analyse a play therapy session between therapist and child. The second review reports some recent findings in the way the brains of people on the autistic spectrum disorder might function. The third paper discusses positive psychology and how such an emerging movement has influenced new research in the field. The last paper reviewed will discuss the issue of the ageing process, and I will present some arguments related to the useful application of qualitative methodologies within this area of research. In conclusion, I will highlight some personal reflections on the Conference and the need for a greater balance between qualitative and quantitative methodologies to be used in collaboration rather than as antagonists.

    Successfully managing fisheries and controlling the spread of invasive species depends on the ability to describe and predict angler behavior. However, finite resources restrict conventional survey approaches and tend to produce retrospective data that are limited in time or space and rely on intentions or attitudes rather than actual behavior. In this study, we used three years of angler data from a popular mobile fishing application in Alberta, Canada, to determine province-wide, seasonal patterns of (1) lake popularity that were consistent with conventional data and (2) anthropogenic lake connectivity that has not been widely described in North America. Our proof-of-concept analyses showed that mobile apps can be an inexpensive source of high-resolution, real-time data for managing fisheries and invasive species. We also identified key challenges that underscore the need for further research and development in this new frontier that combines big data with increased stakeholder interaction and cooperation.

  4. "Our power to remodel civilization": the development of eugenic feminism in Alberta, 1909-1921.

    In addition to being a prominent political figure in equal rights legislation, Emily Murphy was a vital contributor to programs which sought to improve the human race through forced sterilization. These negative aspects of this period in feminist history tend to be described as outside of the women's sphere, representing instead the patriarchal realm of men. However, both eugenics and the first-wave feminist ambitions for equal political rights were connected through an agrarian construction of "mothers of the race." As "mothers of the race," women in Alberta were responsible for the physical and moral betterment of the nation, and were directly engaged in concepts of intelligent motherhood, healthy childhood, and an overarching moral philosophy that was politically driven.

  5. Enigmatic Post-Glacial Degradation and Aggradation of Rivers on the Alberta Plains

    Rivers flowing eastward from the Canadian Rockies across the Alberta plains are situated in narrow flat-bottomed valleys on the order of 50 to 100 m below the plains surface. Post-Laurentide Ice Sheet river history is characterized by (a) incision into the general plains surface following deglaciation, (b) aggradation, soon thereafter, in which up to 25 m of alluvial fill was deposited in the new valleys, and (c) Holocene reincision into the fill, down to depths at least as great as those of the pre-fill valleys. This complicated history probably results from an interplay of (a) isostatic depression/ rebound, which is considered here using a Glacial Isostatic Adjustment model that incorporates the RF2 and RF3 earth models described by Wang et al. (2008) with the ICE4G deglaciation model of Peltier (1994), and (b) variations in sediment flux. The initial incision post-dates the retreat of the Laurentide Ice Sheet eastward across Alberta, ca. 14 ka, and pre-dates the ca. 11 ka alluvial fill. Incision cannot have resulted from general uplift provided by post-glacial isostatic rebound, because rebound was and is generally greater downstream where ice was thicker. Hence river gradients have generally decreased because of rebound. Incision more likely resulted from increased gradients provided by isostatic depression under the center of the ice sheet, relative to the plains gradient that would exist without ice effects. Temporary increased gradients on particular reaches of rivers were provided by the passage across Alberta of the slope of a peripheral bulge on the margin of the isostatic depression. However, some reaches of the rivers have orientations that preclude an obvious connection to bulge gradients. The switch from degradation to aggradation in early post-glacial time was proposed to be a result of decreasing river gradients due to rebound, by Kellerhals and Shaw (1982), but later considered to be a result of influx of paraglacial sediments from the Canadian

    An investigation of ambient air quality was undertaken at three communities within the Athabasca Oil Sands Region (AOSR) of Alberta, Canada (Fort McKay, Fort McMurray, and Fort Chipewyan). Daily and seasonal patterns and 15-year trends were investigated for several criteria air pollutants over the period of 1998 to 2012. A parametric trend detection method using percentiles from frequency distributions of 1h concentrations for a pollutant during each year was used. Variables representing 50th, 65th, 80th, 90th, 95th and 98th percentile concentrations each year were identified from frequency distributions and used for trend analysis. Small increasing concentration trends were observed for nitrogen dioxide (Air quality in Fort Chipewyan was much better and quite separate in terms of absence of factors influencing criteria air pollutant concentrations at the other community stations.

    Traditionally, decision-makers have relied on economic impact estimates derived from conventional economy-wide models. Conventional models lack the environmental linkages necessary for examining environmental stewardship and economic sustainability, and in particular the ability to assess the impact of policies on natural capital. This study investigates environmentally extended economic impact estimation on a regional scale using a case study region in the province of Alberta known as the Foothills Model Forest (FMF). Conventional economic impact models are environmentally extended in pursuit of enhancing policy analysis and local decision-making. It is found that the flexibility of the computable general equilibrium (CGE) modeling approach offers potential for environmental extension, with a solid grounding in economic theory. The CGE approach may be the tool of the future for more complete integrated environment and economic impact assessment.

    The lung transplantation program at the University of Alberta has been in existence for 25 years. The current volume is 35-40 new lung transplants per year. We offer single-lung, bilateral lung, heart/lung and bilateral living lobar transplantation as options. Experience has allowed for widening of the indications and acceptance of patients with more risk. Donor evaluation and management has allowed for extended donors to be included in the donor pool. Results will likely continue to improve with increased understanding of the mechanisms and management of bronchiolitis obliterans syndrome. Our research interests have been in the areas of risk analysis, outcome assessment, and quality of life changes from transplantation.

    A vast reserve of bitumen - oil mixed with sand, clay, and water generally referred to as oil sands - resides in northern Alberta, Canada. Extraction of bitumen and its upgrade to liquid fuel is very energy intensive and generates significant emissions, including nitrogen and sulphur oxides. Satellite observations of NO2 and SO2 vertical column densities have been used to assess the magnitude and distribution of these pollutants throughout the oil sands. Preliminary results indicate a statistically significant enhancement in both species over an area (~30 x 30 km2) of intensive surface mining. Quantifying the burden of these enhancements and their recent changes over such a small area, comparable to the resolution of the best air quality satellite instruments, represents a significant challenge. The methodology used to meet this challenge will be presented, as will initial results including trends over the past decade, comparisons with other large industrial operations, and an assessment of consistency with emission inventories.

    Megaherbivorous dinosaur coexistence on the Late Cretaceous island continent of Laramidia has long puzzled researchers, owing to the mystery of how so many large herbivores (6-8 sympatric species, in many instances) could coexist on such a small (4-7 million km(2)) landmass. Various explanations have been put forth, one of which-dietary niche partitioning-forms the focus of this study. Here, we apply traditional morphometric methods to the skulls of megaherbivorous dinosaurs from the Dinosaur Park Formation (upper Campanian) of Alberta to infer the ecomorphology of these animals and to test the niche partitioning hypothesis. We find evidence for niche partitioning not only among contemporaneous ankylosaurs, ceratopsids, and hadrosaurids, but also within these clades at the family and subfamily levels. Consubfamilial ceratopsids and hadrosaurids differ insignificantly in their inferred ecomorphologies, which may explain why they rarely overlap stratigraphically: interspecific competition prevented their coexistence.

  11. Nuclear energy as a subsurface heavy oil recovery technique (Project Athabasca). [Alberta

    Nuclear energy may become an acceptable thermal recovery technique in the subsurface heavy oil deposits of N. Alberta. The subterranean detonation cavern also may facilitate secondary and tertiary in situ recovery methods, steam injection, and fireflood. Less than 5% of Canada's heavy oil reserves, variously estimated at up to 600-billion bbl, are producible by surface mining. Recovery theory is simple--the nuclear detonation releases both thermal and shock energy to convert otherwise immobile viscous heavy oil deposits into conventionally recoverable hydrocarbons. The proposed Project Athabaska, to employ a 10-kt device, requires exhaustive planning to overcome formidable technical, political, and environmental concerns. Technically, precedent shows that project cost is practically indepencent of yield. The crude oil production unit will comprise a central detonation or emplacement well and several peripheral production wells. Each successive recovery technique will benefit from vastly improved permeability resulting from the prior recovery method.

    Phosphorus losses from agricultural land can cause accelerated eutrophication of surface water bodies. This study evaluated the use of soil test phosphorus (STP) levels to predict dissolved inorganic phosphorus (DIP) concentrations in runoff water from agricultural soils using laboratory rainfall simulation. The objectives of this study were to determine (i) to what extent STP concentrations can be used as a basis to predict P losses from Alberta soils and (ii) how extended rainfall simulation run times affected DIP losses. Soil samples collected from a total of 38 field sites, widely scattered throughout the southern half of Alberta, were subjected to rainfall simulation in the laboratory. The STP concentrations were determined using Miller-Axley, Norwest, Kelowna, Modified Kelowna Mehlich-III, and distilled water extraction methods. Each rainfall simulation event lasted for at least 90 min. Runoff samples were collected in time series for the duration of each simulation, during two distinct runoff intervals: (i) for the first 30 min of continuous runoff (T30) and (ii) for 40 min during runoff equilibrium (Teq). For all the STP extractants and both runoff intervals, the relationship with DIP-flow-weighted mean concentration (FWMC) was linear and highly significant with r2 values ranging from 0.74 to 0.96. However, the slopes of the resulting regression lines were, on average, 1.85 times greater for the T30 runoff interval over those computed for the Teq interval. Thus experimental methodology greatly influenced regression parameters, suggesting that more work was needed to verify these relationships under natural conditions. In addition, with many of the r2 values greater than 0.90 there would be little, if any, benefit derived by including soil properties in regression analysis.

    The eastern slopes of the Rocky Mountains produce the majority of Alberta's surface water supply. While land disturbance affects hydrologic processes governing runoff and water quality, groundwater-surface water interactions may be an important component of catchment resistance to hydrological change. The objectives of this study were to describe reach and sub-catchment coupling of groundwater and surface water processes and to characterize the role of groundwater contribution to surface discharge across spatial and temporal scales. This research is part of Phase II of the Southern Rockies Watershed Project investigating the hydrological effects of three forest harvest treatments (clear-cutting with retention, strip cutting, and partial-cutting) in the front-range Rocky Mountains in the Crowsnest Pass, Alberta. Six nested hydrometric stations in Star Creek (10.4 km2) were used to collect pre-disturbance stream discharge and water quality data (2009-2014). Instantaneous differential streamflow gauging was conducted on reaches ~700 m in length to define stream reaches that were gaining or losing water. Constant rate tracer injection was conducted on gaining reaches to further refine regions of groundwater inputs during high flows, the recession limb of the annual hydrograph, and summer baseflows. Despite being a snow-dominated catchment, groundwater is a major contributor to annual streamflow (60 - 70 %). In general, locations of gaining and losing reaches were consistent across spatial and temporal scales of investigation. A strong losing reach in one sub-basin was observed where underflow may be responsible for the loss of streamflow along this section of the stream. However, strong groundwater upwelling was also observed in a reach lower in the catchment likely due to a "pinch-point" in topographic relief. Spatial and temporal variations in groundwater-surface water interactions are likely important factors in hydrologic resistance to land disturbance.

Data were collected from patients who had a gastroscopy performed by either of 2 family physicians between January 1, 2011, and December 31, 2012. The proportion of patients who had positive test results for H pylori overall and among first-time gastroscopy patients. For first-time gastroscopy patients, the associations between H pylori infection and patient age, sex, residence, and procedural indications and findings were explored. A total of 251 gastroscopies were conducted in 229 unique patients during the study period. Overall, 12.4% (95% CI 8.3% to 16.4%) of patients had positive results for H pylori and among the 159 first-time gastroscopy patients, 17.6% (95% CI 11.7% to 23.5%) had positive test results for H pylori. Helicobacter pylori status did not differ significantly by geography, sex, or age. The prevalence of H pylori was higher among patients with H pylori-related indications for gastroscopy (such as dyspepsia and upper gastrointestinal tract bleeding) than among patients with other indications; however, H pylori infection was not statistically significantly greater in patients diagnosed with peptic ulcer disease. The prevalence of H pylori infection among patients undergoing gastroscopy in rural northern Alberta appears lower than other Canadian estimates. In regions with low H pylori rates, patients with dyspepsia might be better served by acid suppression and nonsteroidal anti-inflammatory drug cessation before investigating for H pylori infection. Population-based research is required to further describe regional differences in H pylori rates. Copyright© the College of Family Physicians of Canada.

    Full Text Available Découverts dans les années 1930, les secteurs de sables bitumineux (ou pétrolifères de l’Ouest canadien sont caractérisés par une intense exploitation, accélérée et stimulée depuis la décennie 1990, liée à l’explosion de la demande mondiale et aux prix élevés du baril de pétrole. Grâce à cette activité, l’Alberta est devenue l’une des provinces les plus dynamiques du Canada. L’exploitation, concédée à des entreprises pétrolières nationales et internationales, contribue à stimuler à la fois l’économie et la démographie de la province, où les revenus et les conditions économiques générales sont devenus particulièrement attractifs. Dans le même temps l’Alberta et le Canada se trouvent en situation délicate par rapport aux engagements internationaux, l’exploitation et la production du pétrole ayant des effets environnementaux importants tels que l’augmentation de la production de gaz à effets de serre, alors que les économies locales et régionales fondent leurs projets de croissance sur les revenus dégagés par cette exploitation.

  17. The downside of downsizing: lessons from the Alberta Energy and Utilities Board

    Energy Technology Data Exchange (ETDEWEB)

    Severson-Baker, C.

    1999-03-01

    Budget and staff cuts at the Alberta Energy and Utilities Board (AEUB) beginning with 1994, and coinciding with the largest increases in oil industry activity in the province, have seriously impaired the ability of the Board to effectively monitor the oil and gas industry. Oil and gas applications at the AEUB have increased from 4,000 in 1993 to 12,000 in 1997. During the same period AEUB reduced staff levels by slashing field staff positions by over 60 per cent and in-the-field time for the remaining regional staff from 70 per cent to 35 per cent. Inability to keep pace with oil and gas activity in the face of budget cuts and staff reductions is evidenced by procedural breakdowns in several areas including oilfield waste management. The questionable application process for an oil field waste treatment facility and the past practice of burying oilfield waste in roadbeds are cited. There is also emerging evidence of industry impacts on human and animal health. Similar downsizing and deregulation is reported to have taken place at Alberta Environmental Protection, which since 1992 suffered a 37 per cent reduction in its funding and a 31 per cent decrease in staff positions. In addition, the government has committed to cut environmental regulations by 50 per cent. Public tolerance for the oil and gas sector in many areas of the province is decreasing. One indication of this is the estimated 160 incidents of acts of sabotage against oil and gas installations and the murder of an oil company executive early in 1998. An upgrading of enforcement capability is urgently needed. A bona-fide Environmental Advocate independent of government control and oil and gas industry funding would be a good start.

  19. The impact of roads on the demography of grizzly bears in Alberta.

    Directory of Open Access Journals (Sweden)

    John Boulanger

    Full Text Available One of the principal factors that have reduced grizzly bear populations has been the creation of human access into grizzly bear habitat by roads built for resource extraction. Past studies have documented mortality and distributional changes of bears relative to roads but none have attempted to estimate the direct demographic impact of roads in terms of both survival rates, reproductive rates, and the interaction of reproductive state of female bears with survival rate. We applied a combination of survival and reproductive models to estimate demographic parameters for threatened grizzly bear populations in Alberta. Instead of attempting to estimate mean trend we explored factors which caused biological and spatial variation in population trend. We found that sex and age class survival was related to road density with subadult bears being most vulnerable to road-based mortality. A multi-state reproduction model found that females accompanied by cubs of the year and/or yearling cubs had lower survival rates compared to females with two year olds or no cubs. A demographic model found strong spatial gradients in population trend based upon road density. Threshold road densities needed to ensure population stability were estimated to further refine targets for population recovery of grizzly bears in Alberta. Models that considered lowered survival of females with dependant offspring resulted in lower road density thresholds to ensure stable bear populations. Our results demonstrate likely spatial variation in population trend and provide an example how demographic analysis can be used to refine and direct conservation measures for threatened species.

    The Canadian Consensus Development Conference on Surveillance and Screening for Antimicrobial-Resistant Organisms (AROs) was sponsored by the Alberta Ministry of Health to provide evidence to update policies for ARO screening in acute care settings. A rigorous evidence-based literature review completed before the conference concluded that that neither universal nor targeted screening of patients was associated with a reduction in hospital-acquired ARO colonization, infection, morbidity, or mortality. Leading international clinicians, scientists, academics, policy makers, and administrators presented current evidence and clinical experience, focusing on whether and how hospitals should screen patients for AROs as part of broader ARO control strategies. An unbiased and independent "jury" with a broad base of expertise from complementary disciplines considered the evidence and released a consensus statement of 22 recommendations. Policy highlights included developing an integrated "One Health" strategy, fully resourcing basic infection control practices, not performing universal screening, and focusing original research to determine what works.

    With the increasing awareness of the need for the reduction of carbon emissions globally, geothermal energy, which offers a potential for cleaner energy generation, is one potential new source. In Alberta, these geothermal resources are likely to be found in the sedimentary basin, or in the deeper crystalline basement rocks. Alberta exhibits a very low geothermal gradient compared to other existing geothermal fields located in areas of volcanic and tectonic activity. To mitigate this effect, the focus in Alberta will involve the development of engineered geothermal systems (EGS) in the target resource. This project is part of the Helmholtz-Alberta Initiative (HAI), which is a research collaboration between scientists in Germany and Canada on energy projects for cleaner energy production. The first goal for EGS research and development is to develop a detailed geological-geophysical characterization of selected sites to delineate potential geothermal reservoirs in Northern Alberta. One of the selected sites is in the Fort McMurray area. Using an existing deep borehole that reaches a depth of 2.3 km into the crystalline basement, our aim is to identify geological features such as zones of fractures in the basin and/or basement that could provide an indication of enhanced fluid flow potential - a necessary component for any geothermal systems to be viable. The earlier stage of our research involves re-processing of surface seismic data. This helps to improve the signal-to-noise ratio for the geological interpretation of the subsurface, such as the locations of saline aquifers and faults that allow heat flow in the rocks, and zones of fractures that may indicate elevated porosity. Current re-processing of the seismic data displays sets of dipping reflectors which may intersect the borehole. Zero offset and walkaway vertical seismic profiles (VSP) were conducted at the borehole for direct comparison with the surface seismic sections. They are also useful in obtaining

    This volume contains a collection of papers delivered by the partici­ pants at the second Conference on Computation and Control held at Mon­ tana State University in Bozeman, Montana from August 1-7, 1990. The conference, as well as this proceedings, attests to the vitality and cohesion between the control theorist and the numerical analyst that was adver­ tised by the first Conference on Computation and Control in 1988. The proceedings of that initial conference was published by Birkhiiuser Boston as the first volume of this same series entitled Computation and Control, Proceedings of the Bozeman Conference, Bozeman, Montana, 1988. Control theory and numerical analysis are both, by their very nature, interdisciplinary subjects as evidenced by their interaction with other fields of mathematics and engineering. While it is clear that new control or es­ timation algorithms and new feedback design methodologies will need to be implemented computationally, it is likewise clear that new problems in computation...

    Governments and physician organizations in Canada have identified current and anticipated future shortages of physicians. The creation of opportunities for licensure for the sizeable population of unlicensed international medical graduates (IMG) residing in Canada can alleviate some of the shortage of medical manpower. We examine whether expenditures on IMG skills assessment, training and licensing are a socially desirable use of resources. We estimate the financial rate of return to Alberta taxpayers from resources allocated to the Alberta International Medical Graduate (AIMG) program, started in 2001. Our estimates show that resources allocated to providing skills assessment and residency training opportunities for IMGs that lead to licensing as a Canadian physician generate real annual rates of return of 9-13%.

    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.

    Full Text Available Abstract Background This study uses geographic information systems (GIS as a tool to evaluate and visualize the general accessibility of areas within the province of Alberta (Canada to cardiac catheterization facilities. Current American and European guidelines suggest performing catheterization within 90 minutes of the first medical contact. For this reason, this study evaluates the populated places that are within a 90 minute transfer time to a city with a catheterization facility. The three modes of transport considered in this study are ground ambulance, rotary wing air ambulance and fixed wing air ambulance. Methods Reference data from the Alberta Chart of Call were interpolated into continuous travel time surfaces. These continuous surfaces allowed for the delineation of isochrones: lines that connect areas of equal time. Using Dissemination Area (DA centroids to represent the adult population, the population numbers were extracted from the isochrones using Statistics Canada census data. Results By extracting the adult population from within isochrones for each emergency transport mode analyzed, it was found that roughly 70% of the adult population of Alberta had access within 90 minutes to catheterization facilities by ground, roughly 66% of the adult population had access by rotary wing air ambulance and that no population had access within 90 minutes using the fixed wing air ambulance. An overall understanding of the nature of air vs. ground emergency travel was also uncovered; zones were revealed where the use of one mode would be faster than the others for reaching a facility. Conclusion Catheter intervention for acute myocardial infarction is a time sensitive procedure. This study revealed that although a relatively small area of the province had access within the 90 minute time constraint, this area represented a large proportion of the population. Within Alberta, fixed wing air ambulance is not an effective means of transporting

    The use of density to measure a species' responses to habitat change remains prevalent despite warnings that relying on such parameters can be misleading. We evaluated whether density was a useful surrogate of habitat quality for the White-throated Sparrow (Zonotrichia albicollis), an apparent habitat generalist, in a recently logged landscape near Calling Lake, Alberta, Canada. We detected significant differences in the territory density of birds among three distinct habitat types: inte...

  12. Preferences of Residents in Four Northern Alberta Communities Regarding Local Post-Secondary Programming

    Full Text Available The western Canadian province of Alberta has used some of the proceeds from exploitation of its extraordinary natural resources to make available a range of post-secondary training and education opportunities to residents. While these provisions appear comprehensive, this study examined how well they actually suit the express needs of the residents of remote, Northern areas of the province, many of them Aboriginal. The literature shows that while Aboriginal people are underrepresented in Canada in university enrollments, they are no longer underrepresented in college or other institutions, suggesting that gains have been made for some residents of rural and remote parts of Canada. Further, when Northern residents (especially Aboriginal males complete advanced training, Statistics Canada reports they are highly successful in employment and income. Access is the pivotal issue, however: leaving the local community to attend training programs elsewhere is often disruptive and unsuccessful. As will be seen, the issue of access arose in this study’s findings with direct implications for distance delivery and support.This study was conducted as part of Athabasca University’s Learning Communities Project (LCP, which sought information about the views and experiences of a broad range of northern Alberta residents concerning their present post-secondary training and education opportunities. The study addresses an acknowledged gap in such information in relation to Canada in comparison with other OECD countries.Results are based on input from 165 individuals, obtained through written surveys (some completed by the researchers in face-to-face exchanges with the respondents, interviews, discussions, and observations, conducted with full-time or part-time residents of the study communities during 2007 and 2008.

    Objectif : La réglementation et le financement public des techniques de procréation assistée (TPA) varient d’une province canadienne à l’autre. En Alberta, les TPA ne sont ni réglementées ni financées par les deniers publics. Nous avons mené cette étude dans le but d’évaluer la rentabilité de l’offre de TPA en Alberta et les effets d’une telle mesure sur le budget albertain en fonction de trois scénarios de politique différents (une politique « restrictive », une politique fondée sur le modèle québécois et une politique « permissive »), par comparaison avec le statu quo. Méthodes : Pour prédire la rentabilité de ces trois options de politique (prévoyant l’offre de TPA financées par les deniers publics en Alberta) et leurs effets sur le budget provincial, nous avons élaboré un modèle économique en combinant un modèle Markov (transitions d’état) et un arbre décisionnel. Le coût par nouveau-né en santé issu d’une grossesse monofœtale constituait le critère d’évaluation principal. Des analyses simples de la variance en matière de sensibilité et des analyses probabilistes ont été menées. Résultats : La politique « restrictive » a constitué l’option la plus rentable dans deux sous-groupes d’âge (< 35 ans et 35-39 ans), tandis que la politique fondée sur l’approche québécoise a constitué l’option la plus rentable dans le sous-groupe des ≥ 40 ans. L’analyse des effets sur le budget (jusqu’à ce que les enfants générés par le modèle ait atteint l’âge de 18 ans) a indiqué l’obtention d’économies de 8,33 millions de dollars pour ce qui est de la politique « restrictive » dans le sous-groupe des < 35 ans. Dans le sous-groupe des ≥ 40 ans, l’option de la politique fondée sur l’approche québécoise a mené à l’obtention d’économies totales de 3,75 millions de dollars. Les analyses de la sensibilité ont indiqué que les résultats modélisés

    Energy Technology Data Exchange (ETDEWEB)

    Gow, A.

    2005-07-01

    This book provides a comprehensive review of the evolving technologies related to oil and gas exploration in the province of Alberta. Oil well drilling technology evolved significantly during the era of conventional oil exploration in the province, from 1883 through 1970. Technologies such as drill bits and power sources were developed largely through trial and error to meet the specific needs of individuals working in the oilfield. The competence and resolve to innovate by drill crews was told through accounts of evolution in drilling processes and equipment, along with personal accounts of those who worked on the rigs. The technology of the oilfield was placed into context with a summary of the history and geology of oil and gas in Alberta. The book also presents a considerate view of events in relation to those who invested in the industry, carried out research drilling and serviced the exploration industry. The first part of the book provides the background to the oil and gas industry. Part 2 examines the earliest technology, the standard cable tool drilling rig, the combination rig and some associated developments in drilling. The third part focuses on the rotary drilling rig and the final part outlines the types of challenges faced by the drillers and the hazards of working on Alberta's rigs. refs., tabs., figs.

  6. Source characteristics and geological implications of the January 2016 induced earthquake swarm near Crooked Lake, Alberta

    2017-08-01

    On 2016 January 12, an intraplate earthquake with an initial reported local magnitude (ML) of 4.8 shook the town of Fox Creek, Alberta. While there were no reported damages, this earthquake was widely felt by the local residents and suspected to be induced by the nearby hydraulic-fracturing (HF) operations. In this study, we determine the earthquake source parameters using moment tensor inversions, and then detect and locate the associated swarm using a waveform cross-correlation based method. The broad-band seismic recordings from regional arrays suggest a moment magnitude (M) 4.1 for this event, which is the largest in Alberta in the past decade. Similar to other recent M ˜ 3 earthquakes near Fox Creek, the 2016 January 12 earthquake exhibits a dominant strike-slip (strike = 184°) mechanism with limited non-double-couple components (˜22 per cent). This resolved focal mechanism, which is also supported by forward modelling and P-wave first motion analysis, indicates an NE-SW oriented compressional axis consistent with the maximum compressive horizontal stress orientations delineated from borehole breakouts. Further detection analysis on industry-contributed recordings unveils 1108 smaller events within 3 km radius of the epicentre of the main event, showing a close spatial-temporal relation to a nearby HF well. The majority of the detected events are located above the basement, comparable to the injection depth (3.5 km) on the Duvernay shale Formation. The spatial distribution of this earthquake cluster further suggests that (1) the source of the sequence is an N-S-striking fault system and (2) these earthquakes were induced by an HF well close to but different from the well that triggered a previous (January 2015) earthquake swarm. Reactivation of pre-existing, N-S oriented faults analogous to the Pine Creek fault zone, which was reported by earlier studies of active source seismic and aeromagnetic data, are likely responsible for the occurrence of the January

  7. Can Decommissioned Oil Pads in Boreal Alberta BE Reclaimed to Carbon Accumulating Peatlands?

    2010-12-01

    In northern Alberta where peatland ecosystems are a dominant landscape feature, construction of oil drilling pads and access roads is a major disturbance. Reclamation of decommissioned oil pads has been hampered by the lack of research. At two decommissioned oil pads at Shell Oil’s Peace River Complex (northeastern Alberta), initially constructed in a bog/fen complex, we established a field experiment to assess reclamation approaches that could lead to a system reflecting undisturbed peatland structure (vegetation composition) and function (net carbon accumulation). In the fall of 2007, mineral soil was removed from two decommissioned pads in areas approximately 100-m x 30-m creating a mineral surface at or near the surrounding bog water table level. We established the following treatments: pad (fertilized vs. unfertilized); water table position (at and 5-cm above the surrounding bog water level); texture (tilling soil amendments into the mineral soil or not); amendment (controls; commercial peat, peat that had been stockpiled in a farmer’s field; landscape fabric; slough hay (native species hay from harvested from local farms), aspen wood chips); planting (in 1-m x 1-m subplots within 2-m x 2-m amendment plots: no planting, 9 Carex aquatilis plants, 5 C. aquatilis and 4 Salix lutea plants; 3 C. aquatilis, 3 S. lutea and 3 Larix laricina seedlings). Treatments were nested (planting within amendment, within texture, within water table level, within pad), with 6 replicate 2-m x 2-m plots of each amendment within each pad x texture x water level combination. Net CO2 exchange was quantified under a range of PAR conditions from full sunlight to complete darkness in each 1-m x 1-m planting subplot repeatedly during the summers of 2008, 2009 and 2010 using closed chambers and infrared gas analyzers. Both dark respiration and maximum net ecosystem production (NEPSAT; net CO2 sequestration when PAR>1000 μmol m-2 s-1) exhibited year x planting interactions (p<0.0001 and

  8. Restoring the Nitrogen Cycle in the Boreal Forest - a Case Study from Northern Alberta

    2014-05-01

    The Athabasca oil sands deposit, located in the boreal forests of Northern Alberta, is one of the largest single oil deposits in the world. This deposit rests underneath 40,200 square kilometres of land. To date, an area of about 715 square kilometres has been disturbed by oil sands mining activity (Government of Alberta, 2013). Following surface mining, companies have the legal obligation to restore soil-like profiles that can support the previous land capabilities (Powter et al., 2012). Because of its importance for site productivity, re-establishment of the nitrogen cycle between these reconstructed soils and plants is one of the most critical factors required to insure long term sustainability of reclaimed boreal landscape. High nitrogen deposition recorded in the oil sands area combined with the high level of nitrate found in reclaimed soils raised concerns about the possibility of these reclaimed soils being in early stages of N saturation (Laxton et al 2010; Hemsley, 2012), although little evidence of net nitrification in these reclaimed soils suggests the contrary (Laxton et al. 2012). To date, results on the behaviour of the nitrogen cycle in the reclaimed sites are contradictory. A systematic study of the nitrogen cycle, and especially rates of gross mineralization, nitrification and denitrification, is needed. Our research aimed at 1) measuring the gross rates of nitrogen transformations under different vegetation treatments in both reclaimed and naturally-disturbed (fire) sites and 2) characterizing the microbial communities participating in the nitrogen cycle within the same soils. A series of 20 soils, covering different vegetation treatments (plots planted with aspen (Populus tremuloides), spruce (Picea glauca) and grassland) were investigated. Gross nitrogen transformation rates were measured using 15N pool-dilution (Müller et al. 2007). Microbial communities participating in the N-cycle were characterized using qPCR and pyrosequencing.

  11. Zapping benzene : a PTAC-sponsored study at the University of Calgary's Schulich School of Engineering explores zapping benzene emissions out of existence with UV light

    Energy Technology Data Exchange (ETDEWEB)

    Stastny, P.

    2009-03-15

    Benzene is primarily used in the petrochemical industry to produce plastics, adhesives and other consumer products. This article described an innovative method to eradicate this carcinogen. According to the Canadian Association of Petroleum Producers, the 2 main sources of human exposure to benzene are tobacco smoke and automobile exhaust. Glycol dehydrators in the oil and gas industry are another primary source. The Petroleum Technology Alliance of Canada (PTAC) is exploring the feasibility of using ultraviolet (UV) light to degrade benzene. It is funding photolysis research at the University of Calgary's Schulich School of Engineering. The photolysis reaction occurs in the atmosphere, where UV components of sunlight initiates reactions. Long wave UV light reaches ground level while shorter, high-energy wavelengths reach the periphery of the earth's atmosphere. It is these short-wavelength UV light that the researchers intend to use to destroy benzene molecules at ground level in their lab. The research is currently at the planning stage. Two mercury lamps that produce UV light at 254 nanometers and 190 nanometers work in tandem to zap the benzene. The 190 nanometre lamp breaks down water molecules to produce hydroxy radicals and ozone. The 254 nanometer lamp breaks down the ozone into highly reactive intermediates that help destroy pollutants. No harmful UV light is emitted during the zapping process, because the lamps are lodged inside pipes that carry waste gas. The gases degrade as they pass by the lamps. Future work will focus on how much energy is needed to complete the process in a timely manner without adding a prohibitive cost to industrial processes. 2 figs.

    2016-06-01

    Lidar measurements of ozone and aerosol were conducted from a Twin Otter aircraft above the oil sands region of northern Alberta. For the majority of the flights, significant amounts of aerosol were observed within the boundary layer, up to an altitude of 2.0 km above sea level (ASL), while the ozone concentration remained at background levels (30-45 ppb) downwind of the industry. On August 24th the lidar measured a separated layer of aerosol above the boundary layer, at a height of 2.0 km ASL, in which the ozone mixing ratio increased to 70 ppb. Backward trajectory calculations revealed that the air containing this separated aerosol layer had passed over an area of forest fires. Directly below the layer of forest fire smoke, pollution from the oil sands industry was observed. Measurements of the backscatter linear depolarization ratio were obtained with a ground based lidar operated by Environment Canada within the oil sands region. The depolarization measurements aided in discriminating between the separate sources of pollution from industry and forest fires. The depolarization ratio was 5-6% in forest fire smoke and 7-10% in the industrial pollution.

As the biggest group of natural resource managers, farmers' behaviour is drawing increasingly wide attention. Satisfying new demands for water will depend on farmers' support since, generally, water will need to be transferred from farmers who have historically secure rights. Although water pricing reform is widely considered to lead to water conservation, the uncertainty of its potential impacts hinders the process of reform. This farmer-level empirical research explores farmers' possible responses to introduction of reforms in water pricing. A survey was conducted of about 300 farm households that use water for irrigating crops in Southern Alberta, an area that is facing water shortages and has had to stop issuing new water licences. By using structural equation modelling, the strength and direction of direct and indirect relationships between external, internal and behavioural variables as proposed in general attitude theory have been estimated. Farming as a family engagement, family members' and family unit's characteristics doubtlessly affect farming practice and farm decisions. Farmers' behaviour was explored under the family and farm context. In developing and testing conceptual models that integrate socio-demographic, psychological, farming context and social milieu factors, we may develop a deeper understanding of farmers' behaviour. The findings and recommendations will be beneficial for environmental practitioners and policy makers.

    2002-06-01

    Resource development in the oil sand industry of Northeastern Alberta is enjoying a wave of renewed interest fuelled in part by changes made in the tax and royalty structure for oil sands developments in the province, the development of new technology and the price of oil. Announcements were made of investments totalling approximately 51 billion dollars in the oil sand industry over the next ten years in all deposits. The issue of cumulative environmental effects has been amplified accordingly. In June 2000, an association was formed, the Cumulative Environmental Management Association (CEMA), consisting of stakeholders and based on consensus, with a mandate to address 72 issues related to potential cumulative impacts in the expanded development of the Wood Buffalo Region. Five working groups were formed, as well as three standing committees. To mitigate the cumulative effects, the working groups and standing committees are working on management objectives, management systems and research recommendations. The regulatory bodies receive the recommendations, and the implementation process involves the issuance of permits and licenses. Research and monitoring activities play a vital role in the environmental management system and are part of other current environmental initiatives. Some of the initiatives are managed by the Wood Buffalo Environmental Association, Regional Aquatics Monitoring Program, and the Canadian Oil Sands Network for Research and Development. These organizations touch on topics including air quality monitoring, aquatics monitoring and environmental research. 1 fig.

    Full Text Available The Athabasca Oil Sands Region of northern Alberta is home to the largest source of S emissions in Canada, and some of the surrounding upland forests are located on acid-sensitive soils. The relative sensitivity of these ecosystems to acidic deposition is largely dependent upon the mineral weathering rate. Weathering rates were evaluated across a range of soils (n = 43 typical of the region using a soil texture approximation (STA and the PROFILE model. The STA was recalibrated for use in the region, and the weathering rates calculated with this method were used to calculate steady-state critical loads of acidity at 333 sites using the Simple Mass Balance (SMB Model and a critical chemical criterion for molar base cation (Ca2+, Mg2+, K+ to aluminium ratio of 10. Soils are dominated by quartz, with small quantities of slowly weatherable minerals, and consequently weathering rates are among the lowest in Canada (median = 11.5 meq m–2 y–1, resulting in very low critical loads. Atmospheric acid (S and N deposition varies considerably across the region, but in general is much lower than impacted areas of central Canada. Under conditions of complete N retention, 34% of the sites receive acid deposition in excess of their critical load; if all N deposition is leached, 62% of the sites are currently exceeded. Acid-sensitive soils in the region are at risk of acidifying due to pressures from industrialization associated with extraction of fossil fuels.

    Full Text Available During the past 15 years, there has been a dramatic increase in the amount of reactive nitrogen (N in the atmosphere, leading to concerns that chronic elevated N deposition may result in negative effects on natural ecosystems. This study examines the response of jack pine (Pinus banksiana plots to N air concentrations within the Athabasca Oil Sands Region (AOSR in northern Alberta, which has experienced elevated N emissions since the 1990s. Air concentrations of nitrogen dioxide (NO2, ammonia, and nitric acid at the study plots are generally low although NO2 is strongly correlated with sulphur dioxide indicating an exposure gradient associated with industrial emissions. Nitrogen concentrations in P. banksiana foliage and two lichen indicator species (Hypogymnia physodes and Evernia mesomorpha were significantly correlated with annual NO2 exposure. Relationships between NO2 (or N exposure and other aspects of N cycling were less evident. Nitrogen content and carbon to nitrogen ratio in the forest floor and soil or potential net N mineralization rates were not correlated with N exposure. Nitrification was negligible suggesting efficient ecosystem immobilization of current N deposition. Based on the response of foliage to N exposure, sites closest to industrial activity appear to be in the early stages of N saturation.

    Chronic pain is a significant problem in children and teens, and adolescents with chronic pain often struggle to attend school on a regular basis. We present in this article a novel program we developed that integrates attendance at a group cognitive-behavioural chronic pain self-management program with earning high school credits. We collaborated with Alberta Education in the development of this course, Chronic Pain 35. Adolescents who choose to enroll are invited to demonstrate their scientific knowledge related to pain, understanding of and engagement with treatment homework, and demonstrate their creativity by completing a project, which demonstrates at least one concept. Integrating Chronic Pain 35 into an adolescent’s academic achievements is a creative strategy that facilitates the engagement of adolescents in learning and adopting pain coping techniques. It also helps teens to advocate for themselves in the school environment and improve their parents’ and teachers’ understanding of adolescent chronic pain. This is one of the first successful collaborations between a pediatric health program and provincial education leaders, aimed at integrating learning and obtaining school credit for learning about and engaging in health self-management for teens. The authors hope this paper serves as an effective reference model for any future collaborating programs aimed at supporting teens with chronic pain to obtain high school credits. PMID:27869766

    The study of olfaction in neurodegeneration has primarily focused on Alzheimer's disease. Research of olfaction in frontotemporal dementia (FTD) has generally not been empirically studied. The current study compared olfaction in FTD to major depressive disorder (MDD) using the Alberta Smell Test (AST). Independent-samples t test results suggested olfaction in FTD was impaired when compared with participants diagnosed with MDD. The AST Total score (out of 20 trials) significantly predicted the diagnostic group and accounted for 40% of the variance in diagnostic group status with an odds ratio of 20.08. Results suggested that a cutoff of ≤2/20 differentiated FTD from MDD with 94% accuracy (91% sensitivity, 97% specificity) and a cutoff of ≤1/20 differentiated the groups with a 95.5% hit rate (91% sensitivity, 100% specificity). Results confirmed olfactory identification deficits in FTD and suggested that the AST is an effective tool for the demarcation of FTD from MDD. This is especially important due to the potential for significant overlap in the behavioral/emotional phenotype and cognitive deficits between the two disorders when presented with early stages of FTD.

  19. THE PREVALENCE OF ALCOHOL-IMPAIRED DRIVING IN EDMONTON, ALBERTA: 1991 – 2009

    Full Text Available This study explores the changes in alcohol-impaired driving among a representative sample of Edmontonians from 1991 to 2009. Based on self-report data from the annual Alberta Surveys of 1991, 1992, 1997, and 2009, this study also traces the shift in the impact of standard demographic factors on alcohol-impaired driving in Edmonton, Alberta. Findings show that self-reported alcohol-impaired driving has decreased substantially over the years (10.6% in 1991, 8.4% in 1992, 7.2% in 1997, and 3.7% in 2009. However, there have been little changes in designated driving. In addition, there have been a shift in age-related impaired driving, i.e., people aged 55-65+ report impaired driving more in 2009 (4.8% compared to 1991 (2.0% and 1992 (2.2%; while individuals aged 18-34 and 35-54 report impaired driving less in 2009 (4.8% and 2.6%, respectively compared to 1991 (12.7% and 13.0%, respectively. Logistic regression analyses indicate that gender is a significant predictor of alcohol-impaired driving in 1991 (OR = 3.29, 95% CI = 1.52–7.16, but not in 2009. However, the interaction between age and gender is not significant. The policy implications of the findings are discussed. Cette étude porte sur les changements dans la conduite affaiblie par l’alcool chez un échantillon représentatif de résidents d’Edmonton entre 1991 et 2009. Fondée sur des déclarations fournies par les automobilistes à l’occasion d’enquêtes annuelles menées en Alberta en 1991, 1992, 1997 et 2009, l’étude décrit aussi des fluctuations dans la portée de facteurs démographiques standard sur la conduite avec facultés affaiblies par l’alcool à Edmonton (Alberta. Les conclusions démontrent une diminution considérable des déclarations de conduite avec facultés affaiblies par l’alcool sur plusieurs années (10,6% en 1991, 8,4% en 1992, 7,2% en 1997, et 3,7% en 2009.

    Full Text Available Industrial emissions in the Athabasca Oil Sands Region (AOSR, Alberta, Canada, have caused concerns about the effect of oil sands operations on the surrounding terrestrial environments, including jack pine (Pinus banksiana Lamb. stands. We collected jack pine needles from 19 sites in the AOSR (13–128 km from main operations for foliar chemical analyses to investigate the environmental impact on jack pine. Pine needles from three age classes, the current annual growth (CAG, 2011, one year and two year old pine needles, were collected. Samples were analyzed for total carbon (TC, nitrogen (TN, and sulfur (TS, inorganic S (SO4-S, base cations (Ca, Mg, Na, and other elements (B, Cu, Fe, Mn, P, Zn; CAG needles were also analyzed for their nitrogen and carbon isotopic compositions. Only TN, TS, Ca, B, Zn, and Fe contents showed weak but significant increases with proximity to the major oil sands operations. C and N isotopic compositions showed no trend with distance or TC and TN contents. Total S contents in CAG of pine foliage increased significantly with proximity to the main industrial operation while foliar inorganic S to organic S ratios (SO4-S/Sorg ranged consistently between 0.13 and 0.32, indicating low to moderately high S loading. Hence, this study suggests some evidence of uptake of S emissions in close proximity to anthropogenic sources, although the reported values have not reached a level of environmental concern.

  1. Airborne Lidar Measurements of Pollution above the Oil Sands Region in Northern Alberta

    2016-01-01

    Full Text Available Lidar measurements of ozone and aerosol were conducted from a Twin Otter aircraft above the oil sands region of northern Alberta. For the majority of the flights, significant amounts of aerosol were observed within the boundary layer, up to an altitude of 2.0 km above sea level (ASL, while the ozone concentration remained at background levels (30-45 ppb downwind of the industry. On August 24th the lidar measured a separated layer of aerosol above the boundary layer, at a height of 2.0 km ASL, in which the ozone mixing ratio increased to 70 ppb. Backward trajectory calculations revealed that the air containing this separated aerosol layer had passed over an area of forest fires. Directly below the layer of forest fire smoke, pollution from the oil sands industry was observed. Measurements of the backscatter linear depolarization ratio were obtained with a ground based lidar operated by Environment Canada within the oil sands region. The depolarization measurements aided in discriminating between the separate sources of pollution from industry and forest fires. The depolarization ratio was 5-6% in forest fire smoke and 7-10% in the industrial pollution.

  2. Spectral decomposition aids AVO analysis in reservoir characterization: A case study of Blackfoot field, Alberta, Canada

    2012-09-01

    Blackfoot field, Alberta, Canada, has produced oil and gas from a Glauconitic compound incised valley-system. In this area channels can be filled with sands and/or shales. Differentiation of prospective channel sands and non-productive shales was always problematic due to the similarity in P-wave impedance of these two lithotypes. We study the spectral decomposition response to the hydrocarbons presence in the Glauconitic channel of Early Cretaceous age. From previous AVO analysis and modeling, a strong Class III AVO anomaly has been observed at the top of the porous sandstone in the upper valley, whereas shale had a very different AVO response. Furthermore, AVO inversion revealed additional information about lithology and fluid content in the channel. Our workflow starts from selecting a continuous horizon that was close and conforms to the channel interval; we then run spectral analyses for the channel area. Short Window Fourier Transform workflow could successfully image the channel's stratigraphic features and confirm results obtained from AVO analysis and inversion run on the data before being stacked. Additionally, the producing oil wells in the sand-fill channel were found to be correlating with high spectrum amplitude; while the dry wells in the shale-plugged channel fell in low amplitude anomaly.

  3. Breakthroughs in reclamation of oil and gas disturbances in boreal Alberta : removing the wellsite footprint

    This presentation reported on a study that focused on developing best practices for wellsite construction and reclamation on forested lands that will accelerate revegetation and recovery of site capability after disturbance. It addressed 4 key uncertainties regarding impaired site capability caused by wellsite development, notably the factors or combination of factors that lead to impaired site productivity; how long do these factors persist on a disturbed site, and what is the rate of return to original land capability; can these factors be mitigated during the construction phase; and, can these factors be mitigated during reclamation, if not during construction. The study was completed on oil sands exploration wells in northeastern Alberta. Minimizing soil disturbance, particularly that of the rooting zone during initial construction, was shown to greatly enhanced vegetative recovery. It was concluded that a single practice approach to reclamation of oil and gas industry disturbances will have limited success. Active adaptation of construction and reclamation methods to match land types and land use is required.

    The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration. © 2012 John Wiley & Sons Ltd.

    The inadvertent ingestion of contaminated soil can be a major pathway for chemical exposure to humans. Few studies to date have quantified soil ingestion rates to develop exposure estimates for human health risk assessments (HHRA), and almost all of those were for children in suburban/urban environments. Here we employed a quantitative mass balance tracer approach on a rural population practicing outdoor activities to estimate inadvertent soil ingestion. This study followed 9 subjects over a 13 day period in Cold Lake, Alberta, near the largest in situ thermal heavy oil (bitumen) extraction operation in the world. The mean soil ingestion rate in this study using Al Ce, La, and Si tracers was 32 mg d(-1), with a 90th percentile of 152 mg d(-1) and median soil ingestion rate of 18 mg d(-1). These soil ingestion values are greater than the standard recommended soil ingestion rates for HHRA from Health Canada, and are similar to soil ingestion estimates found in the only other study on a rural population. © 2013.

    Peoples' perceptions of healthy eating are influenced by the cultural context in which they occur. Despite this general acceptance by health practitioners and social scientists, studies suggest that there remains a relative homogeneity around peoples' perceptions that informs a hegemonic discourse around healthy eating. People often describe healthy eating in terms of learned information from sources that reflect societies' norms and values, such as the Canada Food Guide and the ubiquitous phrase "fruits and vegetables". Past research has examined how built environments shape people's access to healthy living options, such as distribution of grocers versus convenience stores and fast food restaurants. Often overlooked is an in-depth understanding of how social contexts interact with built environments, molding peoples' perceptions of healthy eating. This paper reports on perceptions of healthy eating in four communities across Alberta, Canada. A photovoice methodology was employed to elicit perceptions of healthy eating with 35 participants. This study illustrates how participants' photographs and their stories convey multiple meanings about healthy eating within their own lives and communities. Findings suggest that a 'local' context is an important part of the discourse centered around the promotion of healthy eating practices in these and potential other communities.

    Long-term trends in alpine and prairie snow pack accumulation and melt are affecting streamflow within the Oldman River Basin in southern Alberta, Canada. Unchecked rural and urban development also has contributed to changes in water quality, including enhanced microbial populations and increased waterborne pathogen occurrence. In this study we look at changing environment within the Oldman River Basin and its impact on water quality and quantity. The cumulative effects include a decline in net water supplies, and declining quality resulting in increased risk of disease. Our data indicates that decreases in the rate of flow of water can result in sedimentation of bacterial contaminants within the water column. Water for ecosystems, urban consumption, recreation and distribution through irrigation is often drawn from waterholding facilities such as dams and weirs, and concern must be expressed over the potential for contaminate build-up and disproportionate potential of these structures to pose a risk to human and animal health. With disruption of natural flow rates for water resulting from environmental change such as global warming and/or human intervention, increased attention needs to be paid to use of best management practices to protect source water supplies.

    Recent Interferometric Synthetic Aperture Radar (InSAR) observations over northern Alberta, Canada show persistent surface uplift occurring at rates of 1-4 cm/year, localized at several sites where the Steam-Assisted Gravity Drainage (SAGD) technique is currently being used to extract bitumen from the Athabasca oil sands. We find that uplift rates above the horizontal injector wells are strongly correlated with rates of steam injection, even though there is a net fluid loss from the reservoir pore space as oil and water are withdrawn through the production wells. In combination with available steam injection and bitumen production data at four sites, we use numerical reservoir flow models to explain how the thermal and geomechanical effects of steam injection on an oil sand reservoir can generate uplift at the surface. Results of our numerical experiments show that persistent surface heave consistent with observed rates can be driven by stress changes in the reservoir due to porous flow and thermal expansion.

  10. Petroleum industry development in Alberta, Canada: The relationship between governments and the private sector

    Energy Technology Data Exchange (ETDEWEB)

    Day, M.J. (Alberta Dept. of Energy, AB (Canada))

    Canada is a federation of ten provinces and two territories. The provinces own and manage their petroleum resources. The location of these resources differs considerably from the markets in which they are consumed. Sustaining the petroleum industry in Alberta necessitates a close working relationship between the federal and provincial levels of government, both of which have taxation-related powers, and a large, complex private sector comprising integrated and non-integrated explorers, producers, marketers and contractors. This relationship recognizes the competitive nature of the petroleum industry and the priorities of the varous governments within which the industry must operate. Fluctuations in international petroleum price, supply and demand cause priorities between governments, between industry and government, and within industry itself, to shift dramatically. Key policy areas for any jurisdiction wishing to sustain a petroleum industry include over-all political and business stability, taxation, repartriation of capital, local participation, exploration access acquisition, retention and return of petroleum rights, worksite safety, environmental protection, information disclosure, resource revenue and conservation, upgrading, transporting, domestic and export marketing and end-product pricing. Frequent consultation with industry associations is critical to maintaining an effective policy balance. 16 figs.

    Full Text Available This study had as its objective to analyze the intraclass reliability of the Alberta Infant Motor Scale (AIMS, in the Brazilian version, in preterm and term infants. It was a methodological study, conducted from November 2009 to April 2010, with 50 children receiving care in two public institutions in Fortaleza, Ceará, Brazil. Children were grouped according to gestational age as preterm and term, and evaluated by three evaluators in the communication laboratory of a public institution or at home. The intraclass correlation indices for the categories prone, supine, sitting and standing ranged from 0.553 to 0.952; most remained above 0.800, except for the standing category of the third evaluator, in which the index was 0.553. As for the total score and percentile, rates ranged from 0.843 to 0.954. The scale proved to be a reliable instrument for assessing gross motor performance of Brazilian children, particularly in Ceará, regardless of gestational age at birth.

    Full Text Available Observations are described from total gaseous mercury (TGM concentrations measured at the Wood Buffalo Environmental Association (WBEA Fort McMurray—Patricia McInnes air quality monitoring station—from 21 October 2010 through 31 May 2013, inclusively. Fort McMurray is approximately 380 km north-northeast of Edmonton, Alberta, and approximately 30 km south of major Canadian oil sands developments. The average TGM concentration over the period of this study was 1.45 ± 0.18 ng∙m−3. Principal component analysis suggests that observed TGM concentrations are correlated with meteorological conditions including temperature, relative humidity, and solar radiation, and also ozone concentration. There is no significant correlation between ambient concentrations of TGM and anthropogenic pollutants, such as nitrogen oxides (NOX and sulphur dioxide (SO2. Principal component analysis also shows that the highest TGM concentrations observed are a result of forest fire smoke near the monitoring station. Back trajectory analysis highlights the importance of long-range transport, indicating that unseasonably high TGM concentrations are generally associated with air from the southeast and west, while unseasonably low TGM concentrations are a result of arctic air moving over the monitoring station. In general, TGM concentration appears to be driven by diel and seasonal trends superimposed over a combination of long-range transport and regional surface-air flux of gaseous mercury.

    2015-01-01

    As the influence of human activities on natural systems continues to expand, there is a growing need to prioritize not only pristine sites for protection, but also degraded sites for restoration. We present an approach for simultaneously prioritizing sites for protection and restoration that considers landscape patterns for a threatened population of grizzly bears (Ursus arctos) in southwestern Alberta, Canada. We considered tradeoffs between bottom-up (food resource supply) and top-down (mortality risk from roads) factors affecting seasonal habitat quality for bears. Simulated annealing was used to prioritize source-like sites (high habitat productivity, low mortality risk) for protection, as well as sink-like sites (high habitat productivity, high mortality risk) for restoration. Priority source-like habitats identified key conservation areas where future developments should be limited, whereas priority sink-like habitats identified key areas for mitigating road-related mortality risk with access management. Systematic conservation planning methods can be used to complement traditional habitat-based methods for individual focal species by identifying habitats where conservation actions (both protection and restoration) have the highest potential utility.

    The 7th IAASS Conference, “Space Safety is No Accident” is an invitation to reflect and exchange information on a number of topics in space safety and sustainability of national and international interest. The conference is also a forum to promote mutual understanding, trust and the widest possible international cooperation in such matters. The once exclusive “club” of nations with autonomous sub-orbital and orbital space access capabilities is becoming crowded with fresh and ambitious new entrants. New commercial spaceports are starting operations and others are being built. In the manned spaceflight arena a commercial market is becoming a tangible reality with suborbital spaceflights and government use of commercial services for cargo and crew transportation to orbit. Besides the national ambitions in space, the international cooperation both civil and commercial is also gaining momentum. In the meantime robotic space exploration will accelerate and with it the need to internationally better regulat...

    The Directorate of Maternal and Child Health and the Family Planning Association of Moldova organized a regional conference, which was held October 18-19, 1994, in Kishinev, Moldova, with the support of the United Nations Population Fund (UNFPA), the World Health Organization (WHO), and the International Planned Parenthood Federation (IPPF). The conference,"Problems of Family Planning in Eastern Europe," was attended by approximately 400 Moldovan delegates of governmental and nongovernmental organizations (NGOs), and by 25 delegates from Romania, Russia, Belarus, the Ukraine, and Georgia. The President of Moldova and the Ministry of Public Health of Moldova gave their approval. The main objectives of the conference were to inform the public about the recommendations of the ICPD, to analyze the status of women's reproductive health and family planning in Eastern Europe, and to find ways of implementing the ICPD Plan of Action. Major problems identified during the conference were: 1) the social and economic problems facing most families; 2) the high rate of morbidity and mortality; 3) the decrease in birth rate; 4) the increase in abortions; 5) the rising incidence of venereal disease; and 6) the absence of an effective family planning system. It was agreed that cooperation between governments and NGOs is essential in designing population programs for each country. The following goals were set: 1) to provide populations with sufficient contraceptives; 2) to actively promote family planning concepts through the mass media; 3) to train specialists and to open family planning offices and centers; 4) to introduce sex education in the curricula of Pedagogical Institutes; and 5) to create national and regional statistical and sociological databases on population issues.

    The twenty-six papers in this volume reflect the wide and still expanding range of Anil Nerode's work. A conference on Logical Methods was held in honor of Nerode's sixtieth birthday (4 June 1992) at the Mathematical Sciences Institute, Cornell University, 1-3 June 1992. Some of the conference papers are here, but others are from students, co-workers and other colleagues. The intention of the conference was to look forward, and to see the directions currently being pursued, in the development of work by, or with, Nerode. Here is a brief summary of the contents of this book. We give a retrospective view of Nerode's work. A number of specific areas are readily discerned: recursive equivalence types, recursive algebra and model theory, the theory of Turing degrees and r.e. sets, polynomial-time computability and computer science. Nerode began with automata theory and has also taken a keen interest in the history of mathematics. All these areas are represented. The one area missing is Nerode's applied mathematica...

  9. 2004 Mutagenesis Gordon Conference

    Dr. Sue Jinks-Robertson

    2005-09-16

    Mutations are genetic alterations that drive biological evolution and cause many, if not all, human diseases. Mutation originates via two distinct mechanisms: ''vertical'' variation is de novo change of one or few bases, whereas ''horizontal'' variation occurs by genetic recombination, which creates new mosaics of pre-existing sequences. The Mutagenesis Conference has traditionally focused on the generation of mutagenic intermediates during normal DNA synthesis or in response to environmental insults, as well as the diverse repair mechanisms that prevent the fixation of such intermediates as permanent mutations. While the 2004 Conference will continue to focus on the molecular mechanisms of mutagenesis, there will be increased emphasis on the biological consequences of mutations, both in terms of evolutionary processes and in terms of human disease. The meeting will open with two historical accounts of mutation research that recapitulate the intellectual framework of this field and thereby place the current research paradigms into perspective. The two introductory keynote lectures will be followed by sessions on: (1) mutagenic systems, (2) hypermutable sequences, (3) mechanisms of mutation, (4) mutation avoidance systems, (5) mutation in human hereditary and infectious diseases, (6) mutation rates in evolution and genotype-phenotype relationships, (7) ecology, mutagenesis and the modeling of evolution and (8) genetic diversity of the human population and models for human mutagenesis. The Conference will end with a synthesis of the meeting as the keynote closing lecture.

    OBJECTIVE: To ascertain the opinions of Alberta physicians about the acceptance of active euthanasia as a medical act (the "medicalization" of active euthanasia) and the reporting of colleagues practising active euthanasia, as well as the sociodemographic correlates. DESIGN: Cross-sectional survey of a random sample of Alberta physicians, grouped by site and type of practice. SETTING: Alberta. PARTICIPANTS: A total of 2002 (46%) of the licensed physicians in Alberta were mailed a 38-item questionnaire in May through July 1991; usable responses were returned by 1391 (69%). RESULTS: Although only 44% of the respondents considered active euthanasia morally "right" at least 70% opted to medicalize the practice if it were legal by restricting it to be performed by physicians and to be taught at medical sites. Even though active euthanasia is criminal homicide in Canada, 33% of the physicians stated that they would not report a colleague participating in the act of anyone, and 40% and 60% stated that they would not report a colleague to medical or legal authorities respectively. Acceptance or rejection of active euthanasia as a medical act was strongly related to religious affiliation and activity (p euthanasia revealed profound incongruities in the opinions of the sample of Alberta physicians concerning their ethical and social duties in the practice of medicine. These data highlight the need for relevant modifications of health education policies concerning biomedical ethics and physicians' obligations to society. PMID:8500030

    The 44 papers in this volume constitute the proceedings of the 2015 Wake Conference, held in Visby on the island of Gotland in Sweden. It is the fourth time this conference has been held. The Wake Conference series started in Visby, where it was held in 2009 and 2011. In 2013 it took place in Copenhagen where it was combined with the International Conference on Offshore Wind Energy and Ocean Energy. In 2015 it is back where it started in Visby, where it takes place at Uppsala University Campus Gotland, June 9th-11th. The global yearly production of electrical energy by wind turbines has grown tremendously in the past decade and it now comprises more than 3% of the global electrical power consumption. Today the wind power industry has a global annual turnover of more than 50 billion USD and an annual average growth rate of more than 20%. State-of-the-art wind turbines have rotor diameters of up to 150 m and 8 MW installed capacity. These turbines are often placed in large wind farms that have a total production capacity corresponding to that of a nuclear power plant. In order to make a substantial impact on one of the most significant challenges of our time, global warming, the industry's growth has to continue for a decade or two yet. This in turn requires research into the physics of wind turbine wakes and wind farms. Modern wind turbines are today clustered in wind farms in which the turbines are fully or partially influenced by the wake of upstream turbines. As a consequence, the wake behind the wind turbines has a lower mean wind speed and an increased turbulence level, as compared to the undisturbed flow outside the farm. Hence, wake interaction results in decreased total production of power, caused by lower kinetic energy in the wind, and an increase in the turbulence intensity. Therefore, understanding the physical nature of the vortices and their dynamics in the wake of a turbine is important for the optimal design of a wind farm. This conference is aimed

    Manure applied to agricultural land at rates that exceed annual crop nutrient requirements can be a source of phosphorus in runoff. Manure incorporation is often recommended to reduce phosphorus losses in runoff. A small plot rainfall simulation study was conducted at three sites in Alberta to evaluate the effects of manure rate and incorporation on phosphorus losses. Treatments consisted of three solid beef cattle manure application rates (50, 100, and 200 kg ha(-1) total phosphorus), an unmanured control, and two incorporation methods (nonincorporated and incorporated with one pass of a double disk). Simulated rain was applied to soils with freshly applied and residual (1 yr after application) manure at 70 mm h(-1) to produce 30 min of runoff. Soil test phosphorus (STP), total phosphorus (TP), and dissolved reactive phosphorus (DRP) concentrations in runoff increased with manure rate for fresh and residual manure. Initial abstraction and runoff volumes did not change with manure rate. Initial abstraction, runoff volumes, and phosphorus concentrations did not change with manure incorporation at Lacombe and Wilson, but initial abstraction volumes increased and runoff volumes and phosphorus concentrations decreased with incorporation of fresh manure at Beaverlodge. Phosphorus losses in runoff were directly related to phosphorus additions. Extraction coefficients (slopes of the regression lines) for the linear relationships between residual manure STP and phosphorus in runoff were 0.007 to 0.015 for runoff TP and 0.006 to 0.013 for runoff DRP. While incorporation of manure with a double disk had no significant effect on phosphorus losses in runoff from manure-amended soils 1 yr after application, incorporation of manure is still recommended to control nitrogen losses, improve crop nutrient uptake, and potentially reduce odor concerns.

    Kimberlite pipes K11, K91 and K252 in the Buffalo Head Hills, northern Alberta show an unusually large abundance (20%) of Type II (no detectable nitrogen) diamonds. Type I diamonds range in nitrogen content from 6 ppm to 3300 ppm and in aggregation states from low (IaA) to complete (IaB). The Type IaB diamonds extend to the lowest nitrogen concentrations yet observed at such high aggregation states, implying that mantle residence occurred at temperatures well above normal lithospheric conditions. Syngenetic mineral inclusions indicate lherzolitic, harzburgitic, wehrlitic and eclogitic sources. Pyropic garnet and forsteritic olivine characterize the peridotitic paragenesis from these pipes. One lherzolitic garnet inclusion has a moderately majoritic composition indicating a formation depth of ˜ 400 km. A wehrlitic paragenesis is documented by a Ca-rich, high-chromium garnet and very CaO-rich (0.11-0.14 wt.%) olivine. Omphacitic pyroxene and almandine-rich garnet are characteristic of the eclogitic paragenesis. A bimodal δ13C distribution with peaks at - 5‰ and - 17‰ is observed for diamonds from all three kimberlite pipes. A large proportion (˜ 40%) of isotopically light diamonds ( δ13C Proterozoic metamorphic age (2.3-2.0 Ga) and hence an unconventional setting for diamond exploration. Buffalo Hills diamonds formed during multiple events in an atypical mantle setting. The presence of majorite and abundance of Type II and Type IaB diamonds suggests formation under sublithospheric conditions, possibly in a subducting slab and resulting megalith. Type IaA to IaAB diamonds indicate formation and storage under lower temperature in normal lithospheric conditions.

    Cultural keystone species (CKS) shape the cultural identify of people through the roles they have in diet, material and spiritual practices. The use of the CKS concept is regarded as a method of addressing linked social and ecological issues. This paper presented the results of using the CKS model in the indigenous community of Fort McKay, Alberta to address, social, ecological and spiritual values in regional mine-land reclamation. Fort McKay is at the epicenter of the existing mine developments. Its residents regard human and environmental health to be be linked and therefore experience the effects of development and subsequent reclamation on both cultural and ecological levels. The community is actively engaged in working with the local mining companies on issues of mine reclamation design. In order to hold meaning to the local people, oil sand operators used the CKS concept in their reclamation efforts to take into account ecological functionality and also address the linked social factors. Five CKS were identified through a literature review and extensive community interviews. The list includes moose, cranberry, blueberry, ratroot and beaver. These 5 CKS were used to focus discussions and make recommendations for relevant land reclamation within Fort McKay traditional territory. The project has influenced the way both the community and oil sands operators engage with reclamation. Lessons learned from this process will help direct reclamation activities on other portions of traditional territory, while offering guidance to other regional developers for addressing cultural values in reclamation on their leases. 15 refs., 1 fig.

    Sources and processes affecting the sulphur cycle in the Canyon Creek watershed in Alberta (Canada) were investigated. The catchment is important for water supply and recreational activities and is also a source of oil and natural gas. Water was collected from 10 locations along an 8 km stretch of Canyon Creek including three so-called sulphur pools, followed by the chemical and isotopic analyses on water and its major dissolved species. The δ(2)H and δ(18)O values of the water plotted near the regional meteoric water line, indicating a meteoric origin of the water and no contribution from deeper formation waters. Calcium, magnesium and bicarbonate were the dominant ions in the upstream portion of the watershed, whereas sulphate was the dominant anion in the water from the three sulphur pools. The isotopic composition of sulphate (δ(34)S and δ(18)O) revealed three major sulphate sources with distinct isotopic compositions throughout the catchment: (1) a combination of sulphate from soils and sulphide oxidation in the bedrock in the upper reaches of Canyon Creek; (2) sulphide oxidation in pyrite-rich shales in the lower reaches of Canyon Creek and (3) dissolution of Devonian anhydrite constituting the major sulphate source for the three sulphur pools in the central portion of the watershed. The presence of H(2)S in the sulphur pools with δ(34)S values ∼30 ‰ lower than those of sulphate further indicated the occurrence of bacterial (dissimilatory) sulphate reduction. This case study reveals that δ(34)S values of surface water systems can vary by more than 20 ‰ over short geographic distances and that isotope analyses are an effective tool to identify sources and processes that govern the sulphur cycle in watersheds.

    Full Text Available Abstract Background Mental health illnesses, such as depression, are responsible for a growing disease burden worldwide. Unfortunately, effective treatment is often impeded by stigmatizing attitudes of other individuals, which have been found to lead to a number of negative consequences including reduced help-seeking behavior and increased social distance. Despite the high prevalence of depression in Canada, little research has been conducted to examine stigma against depression in the Canadian general population. Such information is crucial to understanding the current state of stigmatizing attitudes in the Canadian communities, and framing future stigma reduction initiatives. The objectives of this study were to estimate the percentages of various stigmatizing attitudes toward depression in a general population sample and to compare the percentages by demographics and socioeconomic characteristics. Methods We conducted a cross-sectional telephone survey in Alberta, Canada, between February and June 2006. Random digit dialing was used to recruit participants who were aged 18-74 years old (n = 3047. Participants were presented a case vignette describing a depressed individual, and responded to a 9-item Personal Stigma questionnaire. The percentages of stigmatizing attitudes were estimated and compared by demographic and socioeconomic variables. Results Among the participants, 45.9% endorsed that depressed individuals were unpredictable and 21.9% held the view that people with depression were dangerous. Significant differences in stigmatizing attitudes were found by gender, age, education, and immigration status. A greater proportion of men than women held stigmatizing views on each stigma item. No consistent trend emerged by age in stigma against depression. Participants with higher levels of education reported less stigmatizing attitudes than those with less education. Participants who were not born in Canada were more likely to hold

  18. Structural architecture and glacitectonic evolution of the Mud Buttes cupola hill complex, southern Alberta, Canada

    This paper presents the results of a detailed multidisciplinary study of the deformed bedrock and overlying Quaternary sediments exposed at the Mud Buttes in southern Alberta, Canada. This large, arcuate cupola hill is composed of intensely folded and thrust sandstones, siltstones and mudstones of the Cretaceous Belly River Group. Glacitectonism responsible for the development of this internally complex landform occurred at the margin of the newly defined Prospect Valley lobe of the Laurentide Ice Sheet. Analysis of the deformation structures reveals that construction of this landform occurred in response to at least two phases of south-directed ice sheet advance separated by a period of retreat. The first phase led to the formation of a forward propagating imbricate thrust stack leading to polyphase deformation of the Belly River Group. D1 thrusting led to the detachment of thrust-bound slices of bedrock which were accreted to the base of the developing imbricate stack. This process resulted in the structurally higher and older thrust-slices being progressively ;back-rotated; (tilted), accompanied by D2 thrusting and folding. Further thrusting during D3 was restricted to the core of the Mud Buttes as the deforming sequence accommodated further compression imposed by the advancing ice. Minor oscillations of the ice margin led to localised brittle-ductile shearing (D4) of the bedrock immediately adjacent to the ice contact part of the thrust stack. The second phase of ice advance led to the accretion of a relatively simple thrust and folded sequence seen the northern side of Mud Buttes. The resulting composite thrust moraine was subsequently overridden by ice advancing from the NNW to form a dome-like cupola-hill. This readvance of the Prospect Valley lobe led to the formation of a thin carapace of Quaternary sediments mantling the Mud Buttes which include glacitectonite, till and an organic-rich clay-silt (?palaeosol).

    There is increasing global concern regarding the impacts of large scale land disturbance by wildfire on a wide range of water and related ecological services. This study explores the impact of the 2003 Lost Creek wildfire in the Crowsnest River basin, Alberta, Canada on regional scale sediment sources using a tracing approach. A composite geochemical fingerprinting procedure was used to apportion the sediment efflux among three key spatial sediment sources: 1) unburned (reference) 2) burned and 3) burned sub-basins that were subsequently salvage logged. Spatial sediment sources were characterized by collecting time-integrated suspended sediment samples using passive devices during the entire ice free periods in 2009 and 2010. The tracing procedure combines the Kruskal-Wallis H-test, principal component analysis and genetic-algorithm driven discriminant function analysis for source discrimination. Source apportionment was based on a numerical mass balance model deployed within a Monte Carlo framework incorporating both local optimization and global (genetic algorithm) optimization. The mean relative frequency-weighted average median inputs from the three spatial source units were estimated to be 17% (inter-quartile uncertainty range 0-32%) from the reference areas, 45% (inter-quartile uncertainty range 25-65%) from the burned areas and 38% (inter-quartile uncertainty range 14-59%) from the burned-salvage logged areas. High sediment inputs from burned and the burned-salvage logged areas, representing spatial source units 2 and 3, reflect the lasting effects of forest canopy and forest floor organic matter disturbance during the 2003 wildfire including increased runoff and sediment availability related to high terrestrial erosion, streamside mass wasting and river bank collapse. The results demonstrate the impact of wildfire and incremental pressures associated with salvage logging on catchment spatial sediment sources in higher elevation Montane regions where forest

    Increased size and frequency of wildfires in North America has been linked to changing climate over the past 2-3 decades, raising concerns over impacts of wildfire on downstream water quality. In 2003, the Lost Creek wildfire burned more than 21,000 ha in the highest water yielding area of the Rocky Mountain region of southwestern Alberta (Crowsnest Pass). The objective of this study was to examine initial effects of the fire and post-fire salvage logging on concentrations, yield, and total export of several nitrogen (N) species, and to explore initial recovery of these effects within the first four years after the fire. Streams draining burned and post-fire salvage logged watersheds produced much higher concentrations of total nitrogen (TN), total dissolved nitrogen (TDN), and nitrate (NO3-) compared to reference streams in the first two years following the fire (p logging produced generally similar effects on the concentrations and yields for most N species. The temporal trend for TN, TDN, and NO3- in stream water from burned watersheds was a rapid decline in mean watershed exports over the four seasons after the fire to levels similar to those of the reference watersheds. However, exports of TN were still elevated in the fourth post-fire year in watersheds impacted by the additional disturbance of salvage logging. The effects of the burn were most noticeable (i.e., produced the greatest N concentrations, yields, and exports) during or following higher discharge periods (snowmelt freshet and storm flows) (p < 0.001). Small differences were still evident during base-flow periods, emphasizing the importance of groundwater and subsurface contributions to the headwater streams in this study.

    This study examined trace metal levels in scalp hair taken from 122 children and 27 adult residents of three small northern Alberta (Canada) Indian villages, one of which is situated close to the world's first tar sands oil extraction plants. The three communities studied were: Fort McKay (the exposed village), Fort Chipewyan (also in the tar sands ecosystem but distant from the plants), and Garden River (not in the tar sands ecosystem). Inductively coupled argon plasma emission spectroscopy was used to determine hair sample metal content. Nineteen metals were included in data analysis. Children from Fort McKay had the highest average hair lead, cadmium and nickel levels. Chromium levels were approximately equal in hair from Fort McKay and Garden River children, and significantly elevated above levels found in the hair of Fort Chipewyan children. Children from Garden River showed highest hair levels of eight metals: vanadium, aluminum, iron, manganese, barium, zinc, magnesium and calcium. Fort Chipewyan children had the highest hair levels of copper, but the lowest levels of all other metals. Among adults, hair lead, nickel and cadmium levels were highest in Fort McKay residents, while phosphorous and vanadium were highest in hair from Garden River residents. Bioaccumulation of lead, cadmium, nickel and chromium in hair from Fort McKay residents may be related to exposure to extraction plant pollution. Plant stack emissions are known to contain appreciable amounts of lead, nickel and chromium. Spills into the Athabasca River, until recently the source of Fort McKay drinking water, have been reported from plant wastewater holding ponds, known to contain elevated levels of lead, nickel and cadmium. An increased number of significant metal-metal correlations in hair metal levels for Fort McKay children suggests a richer source of multiple metal exposure, relative to children in the other two communities.

    There has been increased scrutiny of the Alberta oil sands due to their high carbon intensity (CI) relative to conventional crude oil. Relying entirely on public and peer-reviewed data sources, we examine historical trends in the CI of oil sands extraction, upgrading, and refining. Monthly data were collected and interpolated from 1970 to 2010 (inclusive) for each oil sands project. Results show a reduction in oil sands CI over time, with industry-average full-fuel cycle (well-to-wheels, WTW) CI declining from 165 gCO2e MJ-1 higher heating value (HHV) of reformulated gasoline (RFG) to 105 (-12, +9) gCO2e MJ-1 HHV RFG. 2010 averages by production pathways are 102 gCO2e MJ-1 for Mining and 111 gCO2e MJ-1 for in situ. The CI of mining-based projects has declined due to upgrader efficiency improvements and a shift away from coke to natural gas as a process fuel. In situ projects have benefitted from substantial reductions in fugitive emissions from bitumen batteries. Both mining and in situ projects have benefitted from improved refining efficiencies. However, despite these improvements, the CI of oil sands production (on a pathway-average basis) ranges from 12 to 24% higher than CI values from conventional oil production. Due to growing output, total emissions from the oil sands continue to increase despite improved efficiency: total upstream emissions were roughly 65 MtCO2e in 2010, or 9% of Canada’s emissions.

  3. Spatiotemporal heterogeneity in carbon exchange at a restored peatland in Alberta, Canada

    Boreal peatlands store a substantial portion of Earth's soil carbon, but the commercial peat extraction process upsets this carbon-sink dynamic. A best-practices restoration process has been developed that aims to return the vegetation and ecosystem functions of post-extraction peatlands. This includes the blocking and infilling of ditches, leveling of the peatland surface and re-introduction of vegetation through the moss layer transfer technique. The dynamics of carbon gas exchange in these restored peatlands are still poorly understood. We investigated ecosystem-scale and microscale carbon flux in a recently restored, post-extraction peatland near Seba Beach, Alberta, Canada. Two eddy covariance (EC) towers continuously measured CO2 and CH4 fluxes in hydrologically distinct parts of the peatland site. Here, we report on growing season measurements made during the fourth year following extraction. Regular static chamber measurements during June-August 2016 were also taken to study gas fluxes across an infilled drainage ditch on the site. Results suggest that if the peatland restoration process successfully returns high water table position, strong carbon uptake may be attained within several years of restoration. However, differences in peatland topography resulted spatial heterogeneity in carbon dynamics at this restored site. A gradient of revegetation success and attendant carbon-flux dynamics were observed, with much stronger net uptake of CO2 and substantial CH4 efflux measured at the tower with higher vegetation cover. Revegetation elsewhere was much sparser, and thus low CO2 uptake rates persisted at much of the peatland, though these conditions conversely inhibited substantial CH4 efflux. More broadly, the contrast in flux data between our two EC towers at the site suggests that attention be made to the selection of representative carbon flux values in similar restored peatlands.

    As part of Fluxnet-Canada, we have been investigating the environmental controls on net ecosystem carbon dioxide exchange using the eddy covariance technique in a moderately rich (treed) fen in northern Alberta, Canada. In addition, integrated CO2 fluxes were compared to carbon stock measurements and rates of peat accumulation. The total ecosystem carbon stock was 52,669 g C m-2 with the vast majority (52,129) accumulated in peat over a 2 meter depth. The basal age for the peat was 2210 ± 50 years before present. The above-ground carbon stock in the two tree species was 226 g C m-2. The oldest Picea mariana trees were aged at 135 years, and they showed a rapid increase in basal area increment starting about 65 years ago that peaked at rates of 2 cm2 yr-1 about 40 years ago. The Larix laricina trees became established approximately 45 years ago and currently have a basal area increment of 3 to 4 cm2 yr-1, much higher than the current rates (0.5 cm2 yr-1) observed for Picea mariana. The rates of peat accumulation were determined on 210Pb-dated cores. Over the last 70 years the peat gained an average of 113 ± 12 g C m-2 yr-1. This was similar to net ecosystem production measured by eddy covariance (95 and 210 g C m-2 yr-1) over the last two years. Variation in annual net ecosystem production was associated with shifts in weather and growing season length. Current and recent historical rates of carbon accumulation were quite consistent despite significant variation in tree species growth and successional changes in this peatland over the last 70 years.

  5. Conventional recovery : new frac technologies plus better royalty rates revive oil-related activity in Alberta

    The revolutionary application of hydraulic fracturing to horizontal wellbores took several years to be deployed on a significant scale in Alberta, even though the technology was locally developed, because the province lacked the appropriate fiscal regime to interest investors. The Province put forward revised drilling incentives, which combined with the prospect of drawing more oil out of known conventional oilfields via multi-stage fracs on horizontal wells has spurred activity. The technology can be used for both oil and gas targets but must be adjusted for differences in permeability in the formations, which results in different fracturing properties. The reduced permeability of tight gas formations also requires a frac treatment an order of magnitude greater than for tight oil formations. Different chemicals and proppant are applied to oil and gas targets. Downhole motors developed for horizontal drilling are now being applied to drilling vertical wells because they create a straighter hole. Oil-based mud is used in drilling shales instead of water-based mud because shales often have clays that interact with water. The oil reduces the lifespan of the rubber liners, so rubber compounds that are less susceptible are under development. To complement the efficiencies gained from horizontal fracing, a downhole tool that generates a fluid pulse in the reservoir has been developed. The pulse momentarily expands the rock's pore structure, helping to move fluid through the formation and allowing oil that has never before moved to flow freely. The wave technology is also applicable to remediating wells. 3 figs.

    Full Text Available Abstract Background Canadian funding agencies are no longer content to support research that solely advances scientific knowledge, and key directives are now in place to promote research transfer to policy- and decision-makers. Therefore, it is necessary to improve our understanding of how researchers are trained and supported to facilitate knowledge translation activities. In this study, we investigated differences in health researcher characteristics and knowledge translation activities. Methods Our sample consisted of 240 health researchers from three Alberta universities. Respondents were classified by research domain [basic (n = 72 or applied (n = 168] and faculty [medical school (n = 128 or other health science (n = 112]. We examined our findings using Mode I and Mode II archetypes of knowledge production, which allowed us to consider the scholarly and social contexts of knowledge production and translation. Results Differences among health researcher professional characteristics were not statistically significant. There was a significant gender difference in the applied researcher faculty group, which was predominantly female (p p p = .01; Mode II, p p = .025 and number of publications (medical school > other faculties; p = .004. There was an interaction effect for research domain and faculty group for number of publications (p = .01, in that applied researchers in medical faculties published more than their peers in other faculty groups. Conclusion Our findings illustrate important differences between health researchers and provide beginning insights into their professional characteristics and engagement in Mode I and Mode II activities. A future study designed to examine these dimensions in greater detail, including potential covariates across more varied institutions, would yield richer insights and enable an examination of relative influences, needs and costs of each mode of activity.

    During 19-21 June 2013 a heavy precipitation event affected southern Alberta and adjoining regions, leading to severe flood damage in numerous communities and resulting in the costliest natural disaster in Canadian history. This flood was caused by a combination of meteorological and hydrological factors, which are investigated from weather and climate perspectives with the fifth generation Canadian Regional Climate Model. Results show that the contribution of orographic ascent to precipitation was important, exceeding 30 % over the foothills of the Rocky Mountains. Another contributing factor was evapotranspiration from the land surface, which is found to have acted as an important moisture source and was likely enhanced by antecedent rainfall that increased soil moisture over the northern Great Plains. Event attribution analysis suggests that human induced greenhouse gas increases may also have contributed by causing evapotranspiration rates to be higher than they would have been under pre-industrial conditions. Frozen and snow-covered soils at high elevations are likely to have played an important role in generating record streamflows. Results point to a doubling of surface runoff due to the frozen conditions, while 25 % of the modelled runoff originated from snowmelt. The estimated return time of the 3-day precipitation event exceeds 50 years over a large region, and an increase in the occurrence of similar extreme precipitation events is projected by the end of the 21st century. Event attribution analysis suggests that greenhouse gas increases may have increased 1-day and 3-day return levels of May-June precipitation with respect to pre-industrial climate conditions. However, no anthropogenic influence can be detected for 1-day and 3-day surface runoff, as increases in extreme precipitation in the present-day climate are offset by decreased snow cover and lower frozen water content in soils during the May-June transition months, compared to pre

  11. A focused ethnographic study of Alberta cattle veterinarians' decision making about diagnostic laboratory submissions and perceptions of surveillance programs.

    Full Text Available The animal and public health communities need to address the challenge posed by zoonotic emerging infectious diseases. To minimize the impacts of future events, animal disease surveillance will need to enable prompt event detection and response. Diagnostic laboratory-based surveillance systems targeting domestic animals depend in large part on private veterinarians to submit samples from cases to a laboratory. In contexts where pre-diagnostic laboratory surveillance systems have been implemented, this group of veterinarians is often asked to input data. This scenario holds true in Alberta where private cattle veterinarians have been asked to participate in the Alberta Veterinary Surveillance Network-Veterinary Practice Surveillance, a platform to which pre-diagnostic disease and non-disease case data are submitted. Consequently, understanding the factors that influence these veterinarians to submit cases to a laboratory and the complex of factors that affect their participation in surveillance programs is foundational to interpreting disease patterns reported by laboratories and engaging veterinarians in surveillance. A focused ethnographic study was conducted with ten cattle veterinarians in Alberta. Individual in-depth interviews with participants were recorded and transcribed to enable thematic analysis. Laboratory submissions were biased toward outbreaks of unknown cause, cases with unusual mortality rates, and issues with potential herd-level implications. Decreasing cattle value and government support for laboratory testing have contributed to fewer submissions over time. Participants were willing participants in surveillance, though government support and collaboration were necessary. Changes in the beef industry and veterinary profession, as well as cattle producers themselves, present both challenges and opportunities in surveillance.

    Collectively, the most common acute cardiac presentations to emergency departments are acute coronary syndromes (ACSs) and heart failure. We examined geographic variation and clustering in emergency department presentations by adults for ACS or heart failure in Alberta in 2010/11. All emergency department presentations for ACS or heart failure made by Alberta residents aged 35 years or more during 2010/11 were extracted from 5 linked population-based Alberta administrative health databases. Data extracted included demographic characteristics, hospital admissions and physician claims. Spatial scan tests and logistic regression analyses were performed. There were 6342 patients with ACS (mean age 65.9 yr, 63.1% male) and 4780 patients with heart failure (mean age 76.6 yr, 49.9% male). For both ACS and heart failure, a primary cluster and 2 secondary clusters were identified. Different clusters were identified for the 2 conditions. For both conditions, patients living in the clusters had more primary care physician claims, prior emergency department visits and prior hospital admissions than did patients living outside the clusters. However, they were less likely to have had a specialist claim in the prior 2 years (odds ratio 0.64 [95% confidence interval 0.56-0.73] for ACS and 0.51 [95% confidence interval 0.43-0.61] for heart failure). Geographic areas were identified with higher numbers than expected of patients presenting to the emergency department for ACS or heart failure. Lower specialist access in these areas was associated with increased emergency department use. Copyright 2017, Joule Inc. or its licensors.

    Full Text Available Abstract Between 2002 and 2007, travel related cases of Shigella sonnei and S. flexneri in Alberta, Canada were acquired from Central America, the Indian subcontinent and North America. Of this group, resistance to ciprofloxacin and nalidixic acid was identified in isolates from patients who had travelled to the Indian subcontinent. This study provides a Canadian perspective to a growing body of literature linking ciprofloxacin and nalidixic acid resistance to travel to the Indian subcontinent. Shigella is a common cause of diarrheal illness in North America with a rate of 2.0 per 100,000 in Canada 1 and a rate of 3.2 per 100,000 in the United States 23. Imported cases of Shigella infections have been reported in developed countries following travel to a foreign or developing country 45 and may be impacted by factors including socio-economic factors 6, food distribution networks 5 and microbiologic factors 7. Across multiple geographic regions, high rates of antimicrobial resistance to multiple agents (e.g. sulfonamides, tetracycline, chloramphenicol, ampicillin, and trimethoprim-sulfamethoxazole have limited the choices for empiric antimicrobial therapy required to manage Shigella infections and reduce fecal excretion of the bacteria 8910 with descriptions of shifting species dominance and changes in antimicrobial susceptibility 1011. Generally, Shigella flexneri and Shigella sonnei are the dominant species and are heavily impacted by changes in antimicrobial susceptibility 1213. This study identifies the global regions associated with travel-related cases of S. flexneri and S. sonnei in Alberta, Canada and compares antibiotic resistance patterns of these isolates for 2002 to 2007 inclusive. Specimens collected 2002-2007 (inclusive from S. flexneri and S. sonnei infections in Alberta, Canada were included for study. Data collected at time of specimen submission included: date of specimen collection, outbreak association if present, travel

    Parent-Child Assistance Program (P-CAP) is a 3-year home visitation/harm reduction intervention to prevent alcohol exposed births, thereby births with fetal alcohol spectrum disorder, among high-risk women. This article used a decision analytic modeling technique to estimate the incremental cost-effectiveness ratio and the net monetary benefit of the P-CAP within the Alberta Fetal Alcohol Spectrum Disorder Service Networks in Canada. The results indicate that the P-CAP is cost-effective and support placing a high priority not only on reducing alcohol use during pregnancy, but also on providing effective contraceptive measures when a program is launched.

    Mineral soil and fibric peat from acid-sensitive western boreal catchments in the Athabasca Oil Sands Region of Alberta, Canada were evaluated for their ability to adsorb and release SO(4)(2-). Laboratory batch studies indicated that SO(4)(2-) adsorption in mineral soil from both the A and B horizons exhibits a limited response to elevated SO(4)(2-) concentrations, with the slope of initial mass isotherms mineral soils and the potential drought-induced S release from peatlands in this region where increased S deposition is expected, further investigation of acidification impacts is warranted.

    Coordinated partnerships and collaborations can optimize the efficiency and effectiveness of service and program delivery in organizational networks. However, the extent to which organizations are working together to promote physical activity, and use physical activity policies in Canada, is unknown. This project sought to provide a snapshot of the funding, coordination and partnership relationships among provincial active living organizations (ALOs) in Alberta, Canada. Additionally, the awareness, and use of the provincial policy and national strategy by the organizations was examined. Provincial ALOs (N = 27) answered questions regarding their funding, coordination and partnership connections with other ALOs in the network. Social network analysis was employed to examine network structure and position of each ALO. Discriminant function analysis determined the extent to which degree centrality was associated with the use of the Active Alberta (AA) policy and Active Canada 20/20 (AC 20/20) strategy. The funding network had a low density level (density = .20) and was centralized around Alberta Tourism Parks and Recreation (ATPR; degree centralization = 48.77%, betweenness centralization = 32.43%). The coordination network had a moderate density level (density = .31), and was low-to-moderately centralized around a few organizations (degree centralization = 45.37%, betweenness centrality = 19.92%). The partnership network had a low density level (density = .15), and was moderate-to-highly centralized around ATPR. Most organizations were aware of AA (89%) and AC 20/20 (78%), however more were using AA (67%) compared to AC 20/20 (33%). Central ALOs in the funding network were more likely to use AA and AC 20/20. Central ALOs in the coordination network were more likely to use AC 20/20, but not AA. Increasing formal and informal relationships between organizations and integrating disconnected or peripheral organizations could increase the capacity of the

    This article describes the implementation and evaluation of a Healthy Communities Initiative (HCI) by the David Thompson Health Region in central Alberta, Canada. The HCI model provided for a facilitated, community-based, strategic planning process. Its key steps include development of a shared vision of health, assessment of needs and strengths, selection of key priority areas for action, and implementation of strategies to achieve change. A three-level evaluation model was developed, which incorporates project-level evaluation, cluster-level evaluation, and critical reflection on the David Thompson Health Region's own capacity to engage in community development work.

    The focus of prior applications of hot-dry-rock (HDR) technology was mostly aimed at generating electricity. In northern Alberta, the thermal gradient is low and, therefore, this technology is not suitable for electricity generation. On the other hand, the cost of steam and hot water, and environmental impacts, are becoming critical issues in heavy-oil and bitumen recovery in Alberta. Surface generation of steam or hot-water accounts for six percent of Canada's natural gas consumption and about 50 million tons of CO2 emission. Lowered cost and environmental impacts are critical in the widespread use of steam (for in-situ recovery) and hot-water (for surface extraction of bitumen) in this region. This paper provides an extensive analysis of hot-water generation to be used in heavy-oil/bitumen recovery. We tested different modeling approaches used to determine the amount of energy produced during HDR by history matching to example field data. The most suitable numerical and analytical models were used to apply the data obtained from different regions containing heavy-oil/bitumen deposits in northern Alberta. The heat generation capacity of different regions was determined and the use of this energy (in the form of hot-water) for surface extraction processes was evaluated. Original temperature gradients were applied as well as realistic basement formation characteristics through an extensive hydro thermal analysis in the region including an experimental well drilled to the depth of 2,500m. Existing natural fractures and possible hydraulic fracturing scenarios were evaluated from the heat generation capacity and the economics points of view. The main problem was modeling difficulties, especially determination and representation of fracture network characteristics. A sensitivity analysis was performed for the selected high temperature gradient regions in Alberta. In this practice, the characteristics of hydraulic fractures, injection rate, depth, the distance between

    Large volumes of oil sands process-affected waters (OSPW) are produced during the extraction of bitumen from oil sand. There are approximately 10(9) m(3) of OSPW currently being stored in settling basins on oil sands mining sites in Northern Alberta. Developers plan to create artificial lakes with OSPW and it is expected that this water may eventually enter the environment. This study was conducted in order to determine if synchronous fluorescence spectroscopy (SFS) could detect OSPW contamination in water systems. Water samples collected from ponds containing OSPW and selected sites in the Alberta oil sands region were evaluated using SFS with an offset value of 18 nm. OSPW ponds consistently displayed a minor peak at 282.5 nm and a broad major peak ranging between 320 and 340 nm. Water from reference sites within the oil sands region had little fluorescence at 282.5 nm but greater fluorescence beyond 345 nm. Naphthenic acids are the major toxic component of OSPW. Both a commercial naphthenic acid and a naphthenic acid extract prepared from OSPW had similar fluorescent spectra with peaks at 280 nm and 320 nm and minor shoulders at approximately 303 and 331 nm. The presence of aromatic acids closely associated with the naphthenic acids may be responsible for unique fluorescence at 320-340 nm. SFS is proposed to be a simple and fast method to monitor the release of OSPW into ground and surface waters in the oil sands region.

  8. Effects of a Severe Mountain Pine Beetle Epidemic in Western Alberta, Canada under Two Forest Management Scenarios

    2010-01-01

    Full Text Available We used a simulation model to investigate possible effects of a severe mountain pine beetle (Dendroctonus ponderosae Hopkins epidemic under two management scenarios in Alberta, Canada. Our simulated outbreak was based on the current epidemic in British Columbia, which may kill close to 80% of the province's pine volume. Our two management scenarios were conventional harvest and a pine-reduction strategy modeled on a component of Alberta's Mountain Pine Beetle Management Strategy. The pine strategy seeks to reduce the number of susceptible pine stands by 75% over the next 20 years through targeted harvesting by the forest industry. Our simulations showed that the pine strategy could not be effectively implemented, even if the onset of the beetle outbreak was delayed for 20 years. Even though we increased mill capacity by 20% and directed all harvesting to high volume pine stands during the pine strategy's surge cut, the amount of highly susceptible pine was reduced by only 43%. Additional pine volume remained within mixed stands that were not targeted by the pine strategy. When the outbreak occurred in each scenario, sufficient pine remained on the landscape for the beetle to cause the timber supply to collapse. Alternative management approaches and avenues for future research are discussed.

  9. A case study in Gantt charts as historiophoty: A century of psychology at the University of Alberta.

    Dawson, Michael R W

    2013-05-01

    History is typically presented as historiography, where historians communicate via the written word. However, some historians have suggested alternative formats for communicating and thinking about historical information. One such format is known as historiophoty, which involves using a variety of visual images to represent history. The current article proposes that a particular type of graph, known as a Gantt chart, is well suited for conducting historiophoty. When used to represent history, Gantt charts provide a tremendous amount of information. Furthermore, the spatial nature of Gantt charts permits other kinds of spatial operations to be performed on them. This is illustrated with a case study of the history of a particular psychology department. The academic year 2009-2010 marked the centennial of psychology at the University of Alberta. This centennial was marked by compiling a list of its full-time faculty members for each year of its history. This historiography was converted into historiophoty by using it as the source for the creation of a Gantt chart. The current article shows how the history of psychology at the University of Alberta is revealed by examining this Gantt chart in a variety of different ways. This includes computing simple descriptive statistics from the chart, creating smaller versions of the Gantt to explore departmental demographics, and using image processing methods to provide measures of departmental stability throughout its history.

    Mycobacterium avium subsp. paratuberculosis (MAP) and Neospora caninum (NC) are two pathogens causing important production limiting diseases in the cattle industry. Significant impacts of MAP and NC have been reported on dairy cattle herds, but little is known about the importance, risk factors and transmission patterns in western Canadian cow-calf herds. In this cross-sectional study, the prevalence of MAP and NC infection in southwest Alberta cow-calf herds was estimated, risk factors for NC were identified, and the reproductive impacts of the two pathogens were assessed. Blood and fecal samples were collected from 840 cows on 28 cow-calf operations. Individual cow and herd management information was collected by self-administered questionnaires and one-on-one interviews. Bayesian estimates of the true prevalence of MAP and NC were computed, and bivariable and multivariable statistical analysis were done to assess the association between the NC serological status and ranch management risk factors, and the clinical effects of the two pathogens. Bayesian estimates of true prevalence indicated that 20% (95% probability interval: 8-38%) of herds had at least one MAP-positive cow, with a within-herd prevalence in positive herds of 22% (8-45%). From the Bayesian posterior distributions of NC prevalence, the median herd-level prevalence was 66% (33-95%) with 10% (4-21%) cow-level prevalence in positive herds. Multivariable analysis indicated that introducing purchased animals in the herd might increase the risk of NC. The negative association of NC with proper carcass disposal and presence of horses on ranch (possibly in relation to herd monitoring and guarding activities), may suggest the importance of wild carnivores in the dynamics of this pathogen in the study area. We also observed an association between MAP and NC serological status and the number of abortions. Additional studies should be done to further examine specific risk factors for MAP and NC, assess the

    many immigrant and ethno-cultural groups in Canada face substantial barriers to accessing health care including language barriers. The negative consequences of miscommunication in health care settings are well documented although there has been little research on communication barriers facing immigrant women seeking maternity care in Canada. This study identified the nature of communication difficulties in maternity services from the perspectives of immigrant women, health care providers and social service providers in a small city in southern Alberta, Canada. a focused ethnography was undertaken incorporating interviews with 31 participants recruited using purposive and snowball sampling. A community liaison and several gatekeepers within the community assisted with recruitment and interpretation where needed (n=1). All interviews were recorded and audio files were transcribed verbatim by a professional transcriptionist. The data was analysed drawing upon principles expounded by Roper and Shapira (2000) for the analysis of ethnographic data, because of (1) the relevance to ethnographic data, (2) the clarity and transparency of the approach, (3) the systematic approach to analysis, and (4) the compatibility of the approach with computer-assisted qualitative analysis software programs such as Atlas.ti (ATLAS.ti Scientific Software Development GmbH, Germany). This process included (1) coding for descriptive labels, (2) sorting for patterns, (3) identification of outliers, (4) generation of themes, (5) generalising to generate constructs and theories, and (6) memoing including researcher reflections. four main themes were identified including verbal communication, unshared meaning, non-verbal communication to build relationships, and trauma, culture and open communication. Communication difficulties extended beyond matters of language competency to those encompassing non-verbal communication and its relation to shared meaning as well as the interplay of underlying pre

  12. A Multi-Faceted Debris-Flood Hazard Assessment for Cougar Creek, Alberta, Canada

    Full Text Available A destructive debris flood occurred between 19 and 21 June 2013 on Cougar Creek, located in Canmore, Alberta. Cougar Creek fan is likely the most densely developed alluvial fan in Canada. While no lives were lost, the event resulted in approximately $40 M of damage and closed both the Trans-Canada Highway (Highway 1 and the Canadian Pacific Railway line for a period of several days. The debris flood triggered a comprehensive hazard assessment which is the focus of this paper. Debris-flood frequencies and magnitudes are determined by combining several quantitative methods including photogrammetry, dendrochronology, radiometric dating, test pit logging, empirical relationships between rainfall volumes and sediment volumes, and landslide dam outburst flood modeling. The data analysis suggests that three distinct process types act in the watershed. The most frequent process is normal or “clearwater” floods. Less frequent but more damaging are debris floods during which excessive amounts of bedload are transported on the fan, typically associated with rapid and extensive bank erosion and channel infilling and widening. The third and most destructive process is interpreted to be landslide dam outbreak floods. This event type is estimated to occur at return periods exceeding 300 years. Using a cumulative magnitude frequency technique, the data for conventional debris floods were plotted up to the 100–300s year return period. A peak-over-threshold approach was used for landslide dam outbreak floods occurring at return periods exceeding 300 years, as not all such events were identified during test trenching. Hydrographs for 6 return period classes were approximated by using the estimated peak discharges and fitting the hydrograph shape to integrate to the debris flood volumes as determined from the frequency-magnitude relationship. The fan volume was calculated and compared with the integrated frequency-magnitude curve to check of the validity of

    Oil sands mines have large disturbance footprints and contain a range of new landforms constructed from mine waste such as shale overburden and the byproducts of bitumen extraction such as sand and fluid fine tailings. Each of these landforms are a potential source of water and chemical release to adjacent surface and groundwater, and consequently, the development of methods to track water migration through these landforms is of importance. The stable isotopes of water (i.e. 2H and 18O) have been widely used in hydrology and hydrogeology to characterize surface water/groundwater interactions but have not been extensively applied in mining applications, or specifically to oil sands mining in northern Alberta. A prerequisite for applying these techniques is the establishment of a Local Meteoric Water Line (LMWL) to characterize precipitation at the mine sites as well as the development of a 'catalogue' of the stable water isotope signatures of various mine site waters. This study was undertaken at the Mildred Lake Mine Site, owned and operated by Syncrude Canada Ltd. The LMWL developed from 2 years (2009/2012) of sample collection is shown to be consistent with other LMWLs in western Canada. The results of the study highlight the unique stable water isotope signatures associated with hydraulically placed tailings (sand or fluid fine tailings) and overburden shale dumps relative to natural surface water and groundwater. The signature associated with the snow melt water on reclaimed landscapes was found to be similar to ground water recharge in the region. The isotopic composition of the shale overburden deposits are also distinct and consistent with observations made by other researchers in western Canada on undisturbed shales. The process water associated with the fine and coarse tailings streams has highly enriched 2H and 18O signatures. These signatures are developed through the non-equilibrium fractionation of imported fresh river water during evaporation from

    The Alberta oil sands contain a vast reservoir of fossil hydrocarbons. The extremely viscous bitumen requires significant energy to extract and upgrade to make a fluid product suitable for pipelines and further refinement. The mining and upgrading process constitute a large industrial complex in an otherwise sparsely populated area of Canada. During the ARCTAS project in June/July 2008, while studying forest fire plumes, the NASA DC-8 and P-3B flew through the plume a total of 5 times. Once was a coordinated visit by both aircraft; the other 3 were fortuitous passes downwind. One study has been published about gas emissions from the complex. Here we concentrate on aerosol emissions and aging. As previously reported, there appear to be at least 2 types of plumes produced. One is an industrial-type plume with vast numbers of ultrafine particles, SO2, sulfate, black carbon (BC), CO, and NO2. The other, probably from the mining, has more organic aerosol and BC together with dust-like aerosols at 3 μm and a 1 μm mode of unknown origin. The DC-8 crossed the plume about 10 km downwind of the industrial site, giving time for the boundary layer to mix and enabling a very crude flux calculation suggesting that sulfate and organic aerosols were each produced at about 500 g/s (estimated errors are a factor of 2, chiefly due to concerns about vertical mixing). Since this was a single flight during a project dedicated to other purposes and operating conditions and weather may change fluxes considerably, this may not be a typical flux. As the plume progresses downwind, the ultrafine particles grow to sizes effective as cloud condensation nucei (CCN), SO2 is converted to sulfate, and organic aerosol is produced. During fair weather in the summer, as was the case during these flights, cloud convection pumps aerosol above the mixed layer. While the aerosol plume is difficult to detect from space, NO2 is measured by the OMI instrument an the Aura satellite and the oil sands plume

    This study investigated the frequency of Salmonella serovars on pig carcasses at various processing steps in two commercial pork processing plants in Alberta, Canada and characterized phenotypic and genotypic antimicrobial resistance (AMR) and PFGE patterns of the Salmonella isolates. Over a one year period, 1000 swab samples were collected from randomly selected pigs at two slaughter plants. Sampling points were: carcass swabs after bleeding (CSAB), carcass swabs after de-hairing (CSAD, plant A) or skinning (CSASk, plant B), carcass swabs after evisceration (CSAE), carcass swabs after pasteurization (CSAP, plant A) or washing (CSAW, plants B) and retail pork (RP). For plant A, 87% of CSAB and 8% of CSAE were positive for Salmonella while at plant B, Salmonella was recovered from 94% of CSAB and 10% of CSAE. Salmonella was not recovered from the RP samples at either plant, indicating that the plants used effective control measures. Salmonella enterica serovar Derby was the most common serotype (23%, 29/127) recovered in plant A and plant B (61%, 76/124). For plant A, 35% (45/127) of isolates were resistant to at least one antimicrobial. Five isolates (3.9%), 4 serovar Ohio strains and one serovar I:Rough-O:I,v:-, strain were simultaneously resistant to antimicrobials of very high (Category I), high (Category II), and medium (Category III) importance to human medicine. The 4 S. Ohio isolates were recovered from 3 different steps of pork processing on the same sampling day and displayed resistance to 5-7 antimicrobials, with all of them displaying resistance to ceftiofur and ceftriaxone (Category I). An I:Rough-O:l,v:- isolate, recovered on a different sampling day, was resistant to 7 antimicrobials that included resistance to ampicillin/clavulanic acid, ceftiofur and ceftriaxone (Category I). Salmonella strains isolated from plant A harbored 12 different AMR genes. The most prevalent genes were sul1, sul2, tet(A), tet(B), aadA, strA/strB, aac(3)IV and aphA1. For

  16. Evaluating the oil sands reclamation process: Assessing policy capacity and stakeholder access for government and non-governmental organizations operating in Alberta's oil sands

    Science.gov (United States)

    Patterson, Tyler

    By employing interpretive policy analysis this thesis aims to assess, measure, and explain policy capacity for government and non-government organizations involved in reclaiming Alberta's oil sands. Using this type of analysis to assess policy capacity is a novel approach for understanding reclamation policy; and therefore, this research will provide a unique contribution to the literature surrounding reclamation policy. The oil sands region in northeast Alberta, Canada is an area of interest for a few reasons; primarily because of the vast reserves of bitumen and the environmental cost associated with developing this resource. An increase in global oil demand has established incentive for industry to seek out and develop new reserves. Alberta's oil sands are one of the largest remaining reserves in the world, and there is significant interest in increasing production in this region. Furthermore, tensions in several oil exporting nations in the Middle East remain unresolved, and this has garnered additional support for a supply side solution to North American oil demands. This solution relies upon the development of reserves in both the United States and Canada. These compounding factors have contributed to the increased development in the oil sands of northeastern Alberta. Essentially, a rapid expansion of oil sands operations is ongoing, and is the source of significant disturbance across the region. This disturbance, and the promises of reclamation, is a source of contentious debates amongst stakeholders and continues to be highly visible in the media. If oil sands operations are to retain their social license to operate, it is critical that reclamation efforts be effective. One concern non-governmental organizations (NGOs) expressed criticizes the current monitoring and enforcement of regulatory programs in the oil sands. Alberta's NGOs have suggested the data made available to them originates from industrial sources, and is generally unchecked by government

    I review recent progress in ultrarelativistic nucleus–nucleus collisions, and the connection of this field to modern QCD theory of deconfinement and/or chiral symmetry restoration. The talks at this Conference have shown a convergence of data and theory as far as the CERN SPS investigations at $\\sqrt{s}=17$ GeV are concerned; the parton–hadron phase boundary seems now located at = 170 ± 10 MeV. New data from RHIC and direct photon production results from CERN have been shown that point out the field’s future direction: analysis of partonic matter at > 200 MeV. Astrophysics analysis was shown to be linked crucially to further theoretical progress with non-perturbative QCD.

    Companion animals closely share their domestic environment with people and have the potential to, act as sources of zoonotic diseases. They also have the potential to be sentinels of infectious and noninfectious, diseases. With the exception of rabies, there has been minimal ongoing surveillance of, companion animals in Canada. We developed customized data extraction software, the University of, Calgary Data Extraction Program (UCDEP), to automatically extract and warehouse the electronic, medical records (EMR) from participating private veterinary practices to make them available for, disease surveillance and knowledge creation for evidence-based practice. It was not possible to build, generic data extraction software; the UCDEP required customization to meet the specific software, capabilities of the veterinary practices. The UCDEP, tailored to the participating veterinary practices', management software, was capable of extracting data from the EMR with greater than 99%, completeness and accuracy. The experiences of the people developing and using the UCDEP and the, quality of the extracted data were evaluated. The electronic medical record data stored in the data, warehouse may be a valuable resource for surveillance and evidence-based medical research.

    The electricity sector has undergone several restructuring activities in the past few years in various jurisdictions. Significant criticism has resulted concerning the objectives, methods and results achieved. Rising prices accompanied by a decrease in the supply of electricity was the consequence of this restructuring in several jurisdictions, while the opposite situation was noted on others. A better understanding of the resulting environment and the necessary tools to adjust to the changing situation are demanded by consumers, producers, municipalities, states and provinces. This conference was designed to allow for essential information on critical issues to reach consumers, power generators and energy service providers. The speakers discussed topics such as developing trends, expectations and implications. The new technologies and the resulting economic opportunities were also reviewed. The conference was divided into eight sessions. Session 1 discussed supply, demand and price outlook 2001-2005, and session 2 dealt with Alberta- moving forward.
