conserving surface-nesting seabirds at the prince edward islands

African Journals Online (AJOL)

South Africa's subantarctic Prince Edward Islands support substantial proportions of the global populations of a number of surface-nesting seabirds. Populations of most of these have decreased at the islands since the 1980s and 12 of 16 species are regarded as Threatened or Near Threatened regionally or internationally.

Full Text Available Abstract Background Late in the 1990s, the non-indigenous European green crab (Carcinus maenas colonized the shorelines of eastern Prince Edward Island, in Atlantic Canada. Due to concerns of further spread into productive shellfish habitats, an annual survey was conducted between 2000 and 2013 to detect a potential range expansion of this species. We compiled and analyzed that data and document green crab expansion using records of annual occurrence and relative density. Methods Surveys were conducted during the fall season of each year by deploying baited traps at 29 sites along the island’s two main shorelines (north and south shores. These sites were selected based on areas deemed more likely to be invaded by the green crab. Raw data per site and date was transformed to catch per unit effort (CPUE to estimate relative abundances. Results Populations of this species showed an uneven westward expansion along the north and south shores. Expansion rates changed among years but, overall, crab abundance was higher and changes in abundance were faster along the south shore than the north shore of the island. The westward expansion continues until this day. Conclusions Based on the information compiled we hypothesize that the dissimilarity in range expansion rate was related to the availability of suitable habitat to sustain large green crab populations along the south shore. We also discuss implications of this expansion for commercial shellfish and native coastal communities.

Modeling effects of nitrate from non-point sources on groundwater quality in an agricultural watershed in Prince Edward Island, Canada

Science.gov (United States)

Jiang, Yefang; Somers, George

2009-05-01

Intensification of potato farming has contaminated groundwater with nitrate in many cases in Prince Edward Island, Canada, which raises concerns for drinking water quality and associated ecosystem protection. Numerical models were developed to simulate nitrate-N transport in groundwater and enhance understanding of the impacts of farming on water quality in the Wilmot River watershed. Nitrate is assumed non-reactive based on δ15N and δ18O in nitrate and geochemical information. The source functions were reconstructed from tile drain measurements, N budget and historical land-use information. The transport model was calibrated to long-term nitrate-N observations in the Wilmot River and verified against nitrate-N measurements in two rivers from watersheds with similar physical conditions. Simulations show groundwater flow is stratified and vertical flux decreases exponentially with depth. While it would take several years to reduce the nitrate-N in the shallow portion of the aquifer, it would take several decades or even longer to restore water quality in the deeper portions of the aquifer. Elevated nitrate-N concentrations in base flow are positively correlated with potato cropping intensity and significant reductions in nitrate-N loading are required if the nitrate level of surface water is to recover to the standard in the Canadian Water Quality Guidelines.

Eucoleus boehmi (Nematoda: Capillariidae) occurs in the nasal conchae and paranasal sinuses of wild and domestic canids. We surveyed the red fox ( Vulpes vulpes ) on Prince Edward Island, Canada, for E. boehmi infection and characterized the associated histopathology. Nasal capillarid infections were detected based on histologic examination of three coronal sections of the nasal cavity and by centrifugal flotation examination (CFE) of rectal feces. Capillarids were detected in histologic sections in 28 of 36 (78%) foxes; detection occurred most frequently in the caudal section (28 foxes) and least in the rostral section (10 foxes). Adult worm morphology was typical for capillarids (stichosome esophagus, bacillary bands, bipolar plugged eggs); E. boehmi eggs were specifically identified based on the characteristic pitted shell wall surface. Adult worms were detected in histologic sections in all 28 and E. boehmi eggs in 21 of the positive foxes. No eggs of Eucoleus aerophilus were observed in any of the sections. Affected foxes had an eosinophilic and lymphoplasmacytic rhinitis with goblet cell hyperplasia. Eggs of E. aerophilus were detected on CFE in 20 of 36 (56%) foxes; 19 of the histologically positive foxes were coinfected with E. aerophilus. Eggs of E. boehmi were detected on CFE in 26 of 36 (72%) foxes and were consistent in size and morphology with those described from wild canids, but they differed from those reported from cases of infection in dogs. Prevalence based on identification of eggs on histologic section or CFE indicated 27 of 36 (75%) red foxes examined were infected with E. boehmi.

Variations in Sense of Place Across Immigrant Status and Gender in Hamilton, Ontario; Saskatoon, Saskatchewan; and, Charlottetown, Prince Edward Island, Canada.

Science.gov (United States)

Gallina, Melissa; Williams, Allison

Past research in Hamilton, Ontario has found that age and longevity of residence are positively associated with evaluations of sense of place (SoP); further, evaluations of SoP between immigrants and Canadian-born individuals have shown no clear pattern (Williams et al. 2010; Williams and Kitchen 2012). This paper builds on this work by further examining evaluations of SoP among both immigrants and Canadian-born residents and across gender in Hamilton, while expanding the study to two other small-to-medium sized cities: Saskatoon, Saskatchewan and, Charlottetown, Prince Edward Island. This paper has two objectives: (1) to establish measures of SoP across immigrant status and gender in Hamilton, Saskatoon, and Charlottetown; and, (2) to determine how SoP varies according to immigrant status, length of residence in Canada, age, income, and neighbourhood length of residence across the three city sites. Telephone survey data (n = 1,132) was used to compare evaluations of SoP across various groups and to construct an ordered logistic regression model for SoP. Results suggest that immigrants tended to rate their SoP lower than their Canadian-born counterparts. Hamilton residents were found to rate their SoP lowest, followed by Saskatoon residents and, finally, Charlottetown residents. Younger individuals, those with lower income levels, and those with shorter neighbourhood residency in the cities concerned were more likely to have lower evaluations of SoP. This research suggests that greater attention is needed to nurture immigrants' connection with their new home.

Incidence and Carrier Frequency of CFTR Gene Mutations in Pregnancies With Echogenic Bowel in Nova Scotia and Prince Edward Island.

Science.gov (United States)

Miller, Michelle E; Allen, Victoria M; Brock, Jo-Ann K

2018-03-01

Fetal echogenic bowel (echogenic bowel) is associated with cystic fibrosis (CF), with a reported incidence ranging from 1% to 13%. Prenatal testing for CF in the setting of echogenic bowel can be done by screening parental or fetal samples for pathogenic CFTR variants. If only one pathogenic variant is identified, sequencing of the CFTR gene can be undertaken, to identify a second pathogenic variant not covered in the standard screening panel. Full gene sequencing, however, also introduces the potential to identify variants of uncertain significance (VUSs) that can create counselling challenges and cause parental anxiety. To provide accurate counselling for families in the study population, the incidence of CF associated with echogenic bowel and the carrier frequency of CFTR variants were investigated. All pregnancies for which CF testing was undertaken for the indication of echogenic bowel (from Nova Scotia and Prince Edward Island) were identified (January 2007-July 2017). The CFTR screening and sequencing results were reviewed, and fetal outcomes related to CF were assessed. A total of 463 pregnancies with echogenic bowel were tested. Four were confirmed to be affected with CF, giving an incidence of 0.9% in this cohort. The carrier frequency of CF among all parents in the cohort was 5.0% (1 in 20); however, when excluding parents of affected fetuses, the carrier frequency for the population was estimated at 4.1% (1 in 25). CFTR gene sequencing identified an additional VUS in two samples. The incidence of CF in pregnancies with echogenic bowel in Nova Scotia and Prince Edward Island is 0.9%, with an estimated population carrier frequency of 4.1%. These results provide the basis for improved counselling to assess the risk of CF in the pregnancy, after parental carrier screening, using Bayesian probability. Counselling regarding VUSs should be undertaken before gene sequencing. Copyright © 2017 Society of Obstetricians and Gynaecologists of Canada. Published by

Potential impacts of wind turbines on birds at North Cape, Prince Edward Island

Energy Technology Data Exchange (ETDEWEB)

Kingsley, A.; Whitman, B.

2001-12-13

As the number of new wind power generating stations in Canada grows, so do concerns regarding the environmental impact of turbines on birds, particularly on raptors and migrating songbirds. These birds are generally at greatest risk of injury or death from turbines, but the impact of these structures on all bird species must be considered on a site-by-site basis. Disturbance to breeding and wintering as a result of turbines must be better researched. This report reviews the literature on the effects of wind turbines on birds, with reference to the North Cape, Prince Edward Island. It recommends ways to reduce potential impacts of turbines on birds in that area, and suggests a program whereby the potential effects of wind turbines on birds can be monitored. The bird groups likely to be seen at North Cape include water birds, raptors, songbirds, and 5 bird species that are considered to be provincially rare. The main causes of bird mortality at wind powered energy facilities are birds flying into rotating turbine blades. Migrating birds are attracted to warning lights on the turbines and collide with the structures and they also collide with the power lines connected to the station. Poor weather conditions, such as fog, increase the occurrence of collisions with towers. Several studies have shown that most migrating and wintering bird species alter their flight paths to avoid turbines. Studies also indicate that bird mortalities at wind energy facilities are not biologically significant and that impacts are not likely to be significant if wind turbines are located in areas of poor habitat and low bird densities. 61 refs., 1 tab., 1 fig.

In Defence of Reason: Religion, Science, and the Prince Edward Island Anti-Abortion Movement, 1969-1988.

Science.gov (United States)

Ackerman, Katrina

2014-01-01

Throughout the 1970s and 1980s, the Prince Edward Island Right to Life Association (RTLA) lobbied medical professionals, hospital boards, politicians, and neighbours to prevent the Charlottetown and Summerside hospital corporations, the only abortion providers on the Island, to eliminate their Therapeutic Abortion Committees. Because abortion committees were not mandatory and only hospital boards were responsible for establishing committees at accredited hospitals, the RTLA elected pro-life members to the boards and voted against abortion committee bylaws to establish barriers to abortion access. By holding key positions within the hospital corporations, pro-life activists ensured that abortion provisions were no longer legally or medically permissible in Island hospitals. This article draws on RTLA and government records, newspaper articles, as well as interviews with pro-life activists, to highlight the avenues through which the organization created a prominent social movement. By contesting the scientific reasoning for abortion, the RTLA quickly became a countermovement not only to the pro-choice movement, but also to the mainstream medical community.

The effect of a smoking ban on hospitalization rates for cardiovascular and respiratory conditions in Prince Edward Island, Canada.

Directory of Open Access Journals (Sweden)

Katherine Gaudreau

Full Text Available This is the first study to have examined the effect of smoking bans on hospitalizations in the Atlantic Canadian socio-economic, cultural and climatic context. On June 1, 2003 Prince Edward Island (PEI enacted a province-wide smoking ban in public places and workplaces. Changes in hospital admission rates for cardiovascular (acute myocardial infarction, angina, and stroke and respiratory (chronic obstructive pulmonary disease and asthma conditions were examined before and after the smoking ban.Crude annual and monthly admission rates for the above conditions were calculated from April 1, 1995 to December 31, 2008 in all PEI acute care hospitals. Autoregressive Integrated Moving Average time series models were used to test for changes in mean and trend of monthly admission rates for study conditions, control conditions and a control province after the comprehensive smoking ban. Age- and sex-based analyses were completed.The mean rate of acute myocardial infarctions was reduced by 5.92 cases per 100,000 person-months (P = 0.04 immediately after the smoking ban. The trend of monthly angina admissions in men was reduced by -0.44 cases per 100,000 person-months (P = 0.01 in the 67 months after the smoking ban. All other cardiovascular and respiratory admission changes were non-significant.A comprehensive smoking ban in PEI reduced the overall mean number of acute myocardial infarction admissions and the trend of angina hospital admissions.

The coastal rove beetles (Coleoptera, Staphylinidae of Atlantic Canada: a survey and new records

Full Text Available The coastline inhabiting rove beetles (Coleoptera: Staphylinidae of Atlantic Canada are surveyed. Thirty-three species have now been recorded in Atlantic Canada including 26 in New Brunswick, 15 in Newfoundland, 31 in Nova Scotia, and 13 on Prince Edward Island. Oligota parva Kraatz, Acrotona avia (Casey, Strigota ambigua (Erichson, and Myrmecopora vaga (LeConte, are all newly recorded in Canada, and Bledius mandibularis Erichson is newly recorded in Atlantic Canada. We retain A. avia as a species distinct from A. subpygmaea Bernhauer and designate a lectotype and paralectotypes for A. avia. Ten new provincial records are reported, one from New Brunswick, six from Nova Scotia, and three from Prince Edward Island. Four functional groups, halobiont (obligate, halophile (facultative, haloxene (tolerant, and incidental coastal species, are distinguished and the fauna is examined from the perspective of the particular coastline habitats and microhabitats they have been found to inhabit. Fourteen of the 33 staphylinids are introduced, Palearctic species, and eight of these have been associated with historic dry ballast shipping to the region from Great Britain. A trophic analysis indicates that some species are phytophagous algae feeders, while others are either generalist predators, or predators specializing on particular taxonomic or functional groups of invertebrates. Finally, some attention is devoted to discussing the diminished areas of coastline environments such as coastal marshes, and the various kinds of environmental disturbances and degradations they have experienced. These indicate the potential vulnerability of such coastal habitats and consequently of the communities of beetles that inhabit them.

Plastic ingestion by fulmars and shearwaters at Sable Island, Nova Scotia, Canada.

Plastic pollution is widespread in the marine environment, and plastic ingestion by seabirds is now widely reported for dozens of species. Beached Northern Fulmars, Great Shearwaters, Sooty Shearwaters and Cory's Shearwaters are found on Sable Island, Nova Scotia, Canada regularly, and they can be used to assess plastic pollution. All species except Cory's Shearwaters contained plastic debris in their gastrointestinal tracts. Northern Fulmars, Sooty Shearwaters and Great Shearwaters all showed high prevalence of plastic ingestion (>72%), with Northern Fulmars having the highest number and mass of plastics among the species examined. There was no difference in plastic ingestion between sexes or age classes. In all species user plastics made up the majority of the pieces found, with industrial pellets representing only a small proportion in the samples. Sable Island could be an important monitoring site for plastic pollution in Atlantic Canada. Copyright © 2014 Elsevier Ltd. All rights reserved.

The Prince Edward Island Conceptual Model for Nursing: a nursing perspective of primary health care.

The philosophy of primary health care (PHC) recognizes that health is a product of individual, social, economic, and political factors and that people have a right and a duty, individually and collectively, to participate in the course of their own health. The majority of nursing models cast the client in a dependent role and do not conceptualize health in a social, economic, and political context. The Prince Edward Island Conceptual Model for Nursing is congruent with the international move towards PHC. It guides the nurse in practising in the social and political environment in which nursing and health care take place. This model features a nurse/client partnership, the goal being to encourage clients to act on their own behalf. The conceptualization of the environment as the collective influence of the determinants of health gives both nurse and client a prominent position in the sociopolitical arena of health and health care.

In Canada, government insurance covers eye care services provided by ophthalmologists and other physicians. However, government coverage for services provided by optometrists, non-medical school trained primary eye care providers, varies regionally. Little is known about the impact of a funding model in which ophthalmologist services are government-insured but services provided by optometrists are not, on eye care utilization and eye disease detection and treatment. We aimed to address this question by examining geographic variations in eye care service utilization on Prince Edward Island (PEI). PEI physician-billing data from 2010 to 2012 was analyzed across five distinct geographic regions (Charlottetown, Summerside, Prince, Queens & Kings and Stratford). The residential location of patients and practice locations of eye care providers were identified using the first three digits of their respective postal code. Age-standardized rates were computed for comparisons across different regions. There were six ophthalmologists practicing on PEI, five with offices in Charlottetown. Twenty optometrists practiced on the island with offices across the province. Stratford is closest and Prince farthest from Charlottetown. Age-standardized utilization rates of ophthalmologists per 100 populations were 10.44 in Charlottetown and 10.90 in Stratford, which was significantly higher than in other regions (7.74-8.92; p Prince and Summerside, the utilization of ophthalmologists by people with diabetes was almost twice as high in Charlottetown (6.49%) than in Prince (3.88%). The observed discrepancies in vision care utilization across geographic regions were likely attributed to barriers in accessing government-insured, geographically concentrated ophthalmologists, as opposed to a reflection of the true differences in eye disease occurrence. The lower prevalence of glaucoma visits in regions farther away from ophthalmologist offices may result in delayed detection and blindness in

Evaluation of buffer zone effectiveness in mitigating the risks associated with agricultural runoff in Prince Edward Island.

To minimize the risk posed by runoff from row crops, Prince Edward Island introduced buffer legislation in 2000. The legislation mandates 10-m and 20-m buffers, respectively, for moderate sloped (i.e. 5%) agricultural fields that border streams. Since 2001, Environment Canada has been evaluating the effectiveness of various buffer widths on operational farms in reducing toxicity and contaminant concentrations in runoff. Sample collectors, placed in 44 fields at the field edge (0m), 10m and at distances out to 30m, collected overland flow following rainfall-induced runoff events. Samples were collected within 24 hours of an event and analysed for seven pesticides (endosulfan, chlorothalonil, carbofuran, linuron, metribuzin, metalaxyl, mancozeb), water quality parameters and Daphnia magna toxicity. The 10-m buffer required for moderate sloped fields was effective at reducing contaminant concentrations but not always to less than lethal concentrations to Daphnia magna. Limited data beyond 10m for fields of both slope types precluded making recommendations on a suitable buffer width for shallow sloped fields and evaluating the effectiveness of 20-m buffers for steep sloped fields. When paired data were combined and statistically tested for all fields, the studied pesticides underwent a 52-98% and 68-100% reduction in aqueous and particulate concentrations within 10m and 30m, respectively. In addition, by 10m, soluble phosphorus, nitrate-nitrogen and total suspended solids were reduced by 34%, 38% and 64%, respectively. Results suggest buffer zones on operational farms are capable of achieving contaminant reductions comparable to those reported for controlled experiments. Inconsistent siting of sample collectors beyond 10m limited the evaluation of the effects of field slope and buffer width on buffer effectiveness on working farms. Future studies on buffer efficiency on operational farms should focus on building the data set beyond 10m and evaluating load reductions

CONCEPTUAL DIFFERENCES BETWEEN THE PACIFIC, ATLANTIC AND ARCTIC TSUNAMI WARNING SYSTEMS FOR CANADA

Directory of Open Access Journals (Sweden)

T.S. Murty

2005-01-01

Full Text Available Canada has coastlines on three of the four oceans on the globe, namely, the Pacific, Atlantic and Arctic oceans. The Pacific and Atlantic oceans are connected to the Arctic Ocean in the north, but still they are three distinct oceans, and need three individual tsunami warning systems. Tsunamis in the Arctic Ocean are not as well documented as in the Pacific and Atlantic oceans. From what is known, tsunamis in the Arctic Ocean are rare and probably are small in amplitude. Because of very low population density, around the Canadian Arctic, at present, there is no priority for a tsunami warning system for Arctic Canada. For the Pacific Ocean, a tsunami warning system is in existence since 1948. In at least one sense, the warning aspects of the tsunami warning system for the Pacific coast of Canada, is relatively simple and straight forward, because it involves only the federal government (PSEPC and the provincial government of British Columbia (PEP. For the Atlantic Ocean, A tsunami warning system is now being established. The warning aspects will be some what more complex for eastern Canada, since it not only involves the federal government, but also five provinces, namely, Newfoundland and Labrador, Nova Scotia, New Brunswick, Prince Edward Island and Quebec. The Alaska tsunami warning center (ATWC in Palmer, Alaska, provides tsunami warnings for both Pacific and Atlantic Canada.

Reactor safety principles which can be learned from, or are reaffirmed by, the accident are reviewed. It is concluded that reactor safety demands a firm commitment to safety by all those involved in the nuclear industry. (auth)

Some economic implications of population dispersion in Canada.

Ridler, N B

In New Brunswick, as in the rest of Atlantic Canada, the quality of life is highly prized, and for many inhabitants this means a rural life style. New Brunswick (with the exception of Prince Edward Island) is the most rural of the Canadian provinces. In addition, over time it is becoming more rural. This paper examines some of the economic implications arising from the rural life style. The provincial government also has expressed concern over rural dispersion in New Brunswick, hence this paper is predominantly policy-oriented. It argues that social costs are considerable, and advocates increased emphasis on user-pay pricing. The intention is not to prohibit rural non-farm residence, but merely to charge rural dwellers a portion of the social costs they impose. The political feasibility of such a policy is open to question, but the alternatives may be increased tax rates or a reduced level of service, and these may be even more politically unpopular.

Green power marketing in Canada: the state of the industry

Dogterom, J.J.; McCulloch, M.; Pape-Salmon, A.

2002-12-01

The introduction of low-impact renewable energy in Canada's electricity supply is being accomplished using a relatively new, market-based initiative called green power marketing. Consumers now have the option of choosing their electricity supplier in two provinces, as a result of electricity market restructuring in those provinces. In some jurisdictions, green power is being offered at a premium price. Green power options are also available in other jurisdictions through the existing vertically integrated power companies. Green power programs are available to residential and commercial sector consumers in Alberta by ENMAX Energy and EPCOR Energy Services Inc. Prince Edward Island (Maritime Electric Company Ltd.) and Saskatchewan (SaskPower) both offer green power programs. The basis for those programs is specific amounts of electricity purchased. The success of the various programs was examined by the Pembina Institute for Appropriate Development, based on installed capacity of green power, consumer enrolment, product design, and environmental benefits. This report presented the results of this evaluation. For the purpose of this report, only those programs in place by the end of 2001 were considered. The environmental impacts of new generation technologies that were implemented as a result of green power marketing programs were analyzed. Historical emission data of the primary generation sources was used as a basis for the investigation and the quantification of the benefits in each province, since different types of power generation are used in the provinces. Greenhouse gases, acid deposition precursors, ground-level ozone precursors, particulate matter, and carbon monoxide are the significant emissions avoided through the use of green power. Included in the emissions reduction analysis in each province considered were life cycle emissions from conventional power sources and green power sources. Alberta, Saskatchewan and Prince Edward Island were the provinces

Geothermal resource assessment of Atlantic Canada: progress report, 1983-1984

Energy Technology Data Exchange (ETDEWEB)

Drury, M.J.

1984-11-01

The program for the assessment of the geothermal energy potential of Atlantic Canada is now in its fifth year. Most of the work - the compilation of existing data, the acquisition of new data on an opportunity basis, and the interpretation of the amassed data base - has been substantially completed. In 1982 the program entered its final phase, that of generating new data at specific targets of interest, at considerably greater cost than earlier phases. In 1983 the various earth science projects were, with the exception of a small data-compilation continuation contract, all site- or area-specific. A test hole was drilled on the campus of the University of Prince Edward Island in Charlottetown, a magnetotelluric survey was conducted across P.E.I., and hydrological studies of two small sedimentary basins were undertaken, in New Brunswick and in Nova Scotia. This report summarizes the results obtained. Some work recently completed is also briefly discussed. 7 refs., 1 fig.

Otolaryngology in Atlantic Canada: practitioners' perspectives.

Science.gov (United States)

Pelausa, E O

1999-02-01

A survey was conducted to assess practice conditions in Atlantic Canada for 1996. Otolaryngologists in Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland/Labrador with at least 1 year of practice experience in the area were canvassed regarding general work concerns, office and OR waiting lists, income, support services, job satisfaction, future plans and personal recommendations for improvement. Nineteen of 40 surveyed responded (47.5%). The results revealed that Atlantic Canadians had to wait considerably longer than average Canadians for ENT services. This was particularly true for Nova Scotians who had to wait often more than double the national average. Forty-seven and a half percent of practitioners were dissatisfied with the practice climate, with many merely trying to maintain status quo. Increasing government constraints and budget cuts have led to practice protectionism and the loss of collegiality. There is little optimism for the future, with 42% predicting continued deterioration in the next 5 years. As a result, up to 58% are considering relocating elsewhere. Despite diminishing returns, these specialists continue to provide the best possible care for their patient patients--hoping for a better tomorrow.

Climatic and Environmental Changes Affecting Communities in Atlantic Canada

Liette Vasseur

2017-07-01

Full Text Available Small rural coastal communities located in Atlantic Canada are vulnerable to the effects of climate and environmental changes. Major storms have impounded the coastline, causing much physical damage and affecting the socioeconomics of these communities that are composed of an aging population. The current study relays findings based on interviews completed in 2011–2012, following the 2010 winter storms in Atlantic Canada. It portrays the physical and social–ecological impacts affecting 10 coastal communities located in the provinces of Québec, New Brunswick, and Prince Edward Island. Semi-structured interviews held in these provinces are the basis for the contributions of this research. The findings reveal physical changes related to coastal erosion from high-wave impacts and storm surge causing flooding of the coastal zone. Also considered are strategies preferred and actually implemented by residents, such as building of protection walls, although undesirable. Due to funding constraints, however, many of these large-scale flood protection projects are not possible without governmental support. Instead, it is suggested that development be controlled and some respondents in this study upheld that relocation be used to alleviate the situation. Finally, more work is required to improve emergency planning. Better concerted short- and long-term responses need to be coordinated by local authorities and higher up in the government in order to ensure the sustainability of these coastal communities.

Current research suggests that pain is a relatively common phenomenon with 60-90% of patients presenting to emergency departments reporting pain (e.g., chest pain, trauma, extremity fractures and migraine headache) that require treatment [Hogan, S.L., 2005. Patient satisfaction with pain management in the emergency department. Advanced Emergency Nursing Journal 27(4), 284-294]. This article explores the use of conceptual theoretical empirical (C-T-E) framework to guide a senior nursing student in a case study of patient with chest pain. The Middle Range Theory of Pain described by Good [Good, M., 1998. A middle-range theory of acute pain management: use in research. Nursing Outlook 46(3), 120-124] and Melzack's [Melzack, R., 1987. The short-form McGill pain questionnaire. Pain, 30, 191-197] short form McGill pain questionnaire were applied along with the Prince Edward Island conceptual model (PEICM) for nursing. Results indicate that the nursing student increased her ability to work in partnership, assess relevant and specific information, and identify a number of strategies to help the patient achieve pain control by using a complement of pharmacological and non-pharmacological interventions. Moreover, the C-T-E approach provided an organized and systematic theoretical approach for the nursing student to assist a patient in pain control.

2013-01-01

Abstract Seventeen Pachybrachis species occurring in eastern Canada [Ontario (ON), Québec (QC), New Brunswick (NB), Nova Scotia (NS), and Prince Edward Island (PE)] are treated by the authors. Two new national records were discovered, both from southernmost Ontario: P. cephalicus Fall and P. luctuosus Suffrian. Four species were new provincial records: P. cephalicus (ON), P. luctuosus (ON, QC), P. obsoletus Suffrian (NB), P. peccans (PE). A fully illustrated key to the Pachybrachis of eastern Canada is provided and supported with extensive photographs, distribution maps, and plant associations. Three species were distributed from southern Ontario into at least one province in the Maritimes (P. nigricornis (Say), P. obsoletus Suffrianand P. peccans Suffrian). Six species were distributed along the shores of the Great Lakes (Erie, Michigan, and Ontario) and rivers (Ottawa, Saguenay and St. Lawrence), but unknown from central and northern ON and QC (P. bivittatus (Say), P. hepaticus hepaticus (F. E. Melsheimer), P. othonus othonus (Say), P. pectoralis (F. E. Melsheimer), P. spumarius Suffrianand P. trinotatus (F. E. Melsheimer)). Seven species were rare, five being found exclusively from southern ON (P. calcaratus Fall, P. cephalicus, P. luridus (Fabricius), P. subfasciatus (J. E. LeConte)and P. tridens (F. E. Melsheimer)), with two having, in addition, a disjunct population in QC (P. atomarius (F. E. Melsheimer)and P. luctuosus). One species was found to be the northern most extension of an eastern United States (US) distribution into the eastern townships of QC (P. m-nigrum (F. E. Melsheimer)). There were no Pachybrachis that could be considered arctic, subarctic, or boreal species; no specimens were found from Labrador and Newfoundland, and all species had southern affinities. Pachybrachis atomarius, P. calcaratus, P. luridus, P. subfaciatus, and P. tridens, not seen over the last 30–70 years, may be extirpated from eastern Canada. PMID:24163583

Onion thrips (Thrips tabaci Lindeman (Thysanoptera: Thripidae)) can be a pest in organic onion production on Prince Edward Island. This study was to examine the effect of planting time and variety on infestation levels and damage by onion thrips on cabbage (Brassicae oleracea capitala (L.)). A field site was planted with 2 main and 8 lesser varieties of cabbage over 4 planting dates. Some varieties were short season and harvested on July 31 with longer season varieties harvested on September 2. Blue sticky traps were used to capture thrips migrating into the field site from July 22-September 2. Traps were counted weekly and cabbage heads within the field site were visually surveyed for thrips. At harvest, heads were weighed and measured, thrips damage was assessed then the head was dissected and thrips counted on the first four layers of the head. Thrips exhibited a preference for Lennox over Bronco throughout the season although thrips populations were not high enough to effect economic damage in 2014. Planting date influenced cabbage head weight and size with later plantings yielding the largest heads. Use of planting date and variety to avoid thrips populations is discussed.

The availability of curative hepatitis C therapies has created an opportunity to improve delivery and access. Local providers, government, industry, and community groups in Prince Edward Island developed an innovative province-wide care model. Our goal was to describe the first year of program implementation. Using a community based prospective observational study design, all chronic hepatitis C referrals received from April 2015 to April 2016 were recorded in a database. Primary analysis assessed the time from referral to assessment/treatment, as well as the number of referrals, assessments, and treatment initiations. Secondary objectives included: 1) Treatment effectiveness using intention-to-treat analysis; and 2) Patient treatment experience assessed using demographics, adverse events, and medication adherence. During the study period 242 referrals were received, 123 patients were seen for intake assessments, and 93 initiated direct-acting antiviral therapy based on medical need. This is compared to 4 treatment initiations in the previous 2 years. The median time from assessment to treatment initiation was 3 weeks. Eighty-two of 84 (97.6%, 95% CI 91.7 - 99.7%) patients for whom outcome data were available achieved sustained virologic response at 12 weeks post-treatment; 1 was lost to follow-up and 1 died from an unrelated event. In the voluntary registry, 39.7% of patients reported missed treatment doses. In conclusion, results from the first 12 months of this multi-phase hepatitis C elimination strategy demonstrate improved access to treatment, and high rates of safe engagement and cure for patients living with chronic hepatitis C genotype 1 infections.

The energy sector : an investment in the people and communities of Atlantic Canada

International Nuclear Information System (INIS)

2008-01-01

The opportunity for Atlantic Canada to meet the North American demand for more energy and increased security was discussed. Energy accounts for nearly half of all exports from Atlantic Canada. The region delivers oil, natural gas and electricity to its own communities and for export around the continent and is poised to significantly increase its reach, given its proximity to the New England States. Over the past decade, the energy industry in Atlantic Canada has laid the foundation for what has become one of the most significant sectors in the regional economy. It has a diverse mix of traditional thermal and hydroelectric generation with newer technology such as nuclear, wind, bioenergy and tidal. The discovery and development of offshore oil and gs fields at the end of the twentieth century significantly enhanced the regional energy sector and shifted the public policy focus from domestic production to the development of export markets. The projects have brought significant outside investment from a broad range of oil and gas companies. This paper listed the projects and players in the energy sector in New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador. The issue of exporting energy resources and importing human resources was also considered. A list of skilled trades, professional services and support services that will be needed by the Atlantic Canadian energy sector over the next decade was also provided. It was noted that employment growth is driven by demographics, technology and the trend for environmental stewardship. 9 refs., 2 tabs

To examine the advantages and disadvantages of two different Health Care Systems from the perspective of Primary Care (PC) physicians. Qualitative research based on the analysis of documents written as diaries for the study. Primary Care in the Canary Islands (Spain) and Alberta (Canada) CONTEXT AND PARTICIPANTS: Intentional sample to identify different profiles of physicians. Participants were asked to write a document describing their work activities, including the impact of the organisational system and on their personal life. Two representatives of the health care system were asked to write a detailed description about how PC is organised in their country. Nine diaries were collected (5 from the Canary Islands and 4 from Alberta). Ritchie & Spencer framework was used for the analysis. In Alberta, physicians have access to more complementary tests; they can offer hospital care; they have to sort out administrative work; they can choose were to work; and can specialise in different types of health care services. In the Canary Islands physicians can have paid holidays and the administrative issues do not depend on them, patients have a physician assigned and seem to have more institutional support. The results of this study allow us to constructively analyse the role of PC physicians, assess the advantages and re-think the disadvantages related to how we work in order to learn from other health care systems.

EDWARD SUESS AND RUSSIAN GEOLOGISTS

Directory of Open Access Journals (Sweden)

Boris A. Natal’in

2011-01-01

Full Text Available The publication is devoted to the history of one of the greatest concepts of tectonics of Asia, that has been widely accepted and yet obliterated with time, while the splendors of this concept are doubtful. Numerous citations in the Russian papers to «The Face of the Earth» by Edward Suess and the fact that he was elected a Corresponding Member of the Imperial Saint Petersburg Academy of Sciences clearly demonstrate how highly Suess’s contribution to studies of the structure and geological evolution of Asia was valued by the Russian geological community. Suess’s letters to Vladimir A. Obruchev give evidence how close and productive the relationship between Edward Suess and the Russian researchers was in the late 19th and the early 20th centuries and also illustrate how the great tectonic concept of Asia [Suess, 1908] was born and developed. The idea of centrifugal propagation of tectonic waves of the Altaids from a continental node located somewhere in Siberia was mainly inspired by Suess’s profound scientific intuition. The idea matured after Edward Suess got acquainted with Ivan D. Chersky’s paper [Черский, 1886] that greatly facilitated in shaping and improving this idea. It was mailed to Suess by Vladimir A. Obruchev who translated the paper, attached his own map and provided explanations to Chersky’s ideas. The available historical documents suggest that Vladimir A. Obruchev facilitated communication between the Russian geologists, on the one side, and Edward Suess and other Austrian geologists who conducted geological studies in Asia, on the other side. Being actively involved in exchange of publications and cooperation in field data processing, Edward Suess was aware of all the details of the Russian geological studies.In addition to the concept of tectonic arcs of the Altaids and descriptions of main geological structures located in Northern Asia and China, Edward Suess adopted a concept of disjunctive dislocations

Integrated fate modeling for exposure assessment of produced water on the Sable Island Bank (Scotian shelf, Canada).

Science.gov (United States)

Berry, Jody A; Wells, Peter G

2004-10-01

Produced water is the largest waste discharge from the production phase of oil and gas wells. Produced water is a mixture of reservoir formation water and production chemicals from the separation process. This creates a chemical mixture that has several components of toxic concern, ranging from heavy metals to soluble hydrocarbons. Analysis of potential environmental effects from produced water in the Sable Island Bank region (NS, Canada) was conducted using an integrated modeling approach according to the ecological risk assessment framework. A hydrodynamic dispersion model was used to describe the wastewater plume. A second fugacity-based model was used to describe the likely plume partitioning in the local environmental media of water, suspended sediment, biota, and sediment. Results from the integrated modeling showed that the soluble benzene and naphthalene components reach chronic no-effect concentration levels at a distance of 1.0 m from the discharge point. The partition modeling indicated that low persistence was expected because of advection forces caused by tidal currents for the Sable Island Bank system. The exposure assessment for the two soluble hydrocarbon components suggests that the risks of adverse environmental effects from produced water on Sable Island Bank are low.

Developmental and spatial variations in the diet signatures of hyperbenthic shrimp Nauticaris marionis at the Prince Edward Islands based on stable isotope ratios and fatty acid profiles

Science.gov (United States)

Richoux, Nicole B.; Allan, E. Louise; Froneman, P. William

2016-04-01

The caridean shrimp Nauticaris marionis is an ecologically important species in the benthic community around the sub-Antarctic Prince Edward Islands (PEI) as it represents a key prey item for a variety of top predators breeding on the islands. We hypothesized that the diet of N. marionis shifts during its development, and that spatial variability in food availability results in differentiation in the diet signatures of specimens collected from various locations of the shelf waters around the PEI. Specimens were collected from nine stations (depth range 70 to 240 m) around the PEI at inter-island shelf (from west to east: upstream, between and downstream) and nearshore regions during austral autumn 2009. Stable isotope and fatty acid data both revealed spatial and developmental variations in the shrimp diet. Nearshore shrimp were more 13C-enriched than those from the inter-island region, suggesting increased kelp detritus entered the food web in the nearshore regions. The shrimp showed increases in δ13C and δ15N signatures (and trophic position) with an increase in body size, resulting in distinctions between size classes that reflected shifts in their trophic niche through development. The fatty acid profiles similarly indicated distinctions in diet with increased shrimp size (in the deep regions), and spatial variability was evident in relation to region and depth. All shrimp contained large proportions of polyunsaturated and essential fatty acids, indicating that the quality of food consumed was similar between regions despite the diet variability. Our results provide new dietary information about a key species operating near the base of the food web at the highly productive PEI, and show that there were no areas of enhanced nutrition available to the shrimp. As such, there was no nutritional advantage to shrimp inhabiting any specific region around the PEI.

The association of organisms with particular habitats and habitat-forming organisms, can strongly influence species distributions, interactions and wider ecosystem services. At the sub-Antarctic Prince Edward Islands, the caridean shrimp Nauticaris marionis is a principal part of the benthic ecosystem, occurring between ca. 50 m and 600 m. Its role as a trophic link between the primary productivity and higher predators is established, but little is understood of its in situ habitat usage and associations or of how these structure patterns of abundance. We investigated these aspects directly using a benthic camera sled, sampling 27 stations between 50 m and 500 m. Substratum type was characterised, and estimates of percentage cover of the 13 main groups of habitat-forming epibenthic taxa were made, alongside absolute counts of N. marionis within 'digital quadrats' drawn from 300 m transects. The distribution of N. marionis was influenced by depth, substratum type and overall biogenic cover, being limited to habitats between 50 and 160 m depth on mud or gravel substrata only, and having > 50% biogenic cover. The presence/absence of N. marionis related to significantly different epibenthic assemblages (termed biogenic habitats), but this effect was contingent on depth. Likewise, densities of N. marionis were significantly affected by biogenic habitat type, identifying an association with two biogenic habitat groups, one dominated by red-algae, the other by structurally complex bryozoan species. These associations likely relate to the structural complexity of the two habitat groups, rather than the specific taxa involved. The apparent absence of N. marionis at depths > 160 m contrasts with earlier records and poses questions about the trophic importance of the shrimp in deeper habitats.

Full Text Available Study region: This study is conducted in the Magdalen Islands (Québec, Canada, a small archipelago located in the Gulf of St. Lawrence. Study focus: This work was undertaken to support the design of a long-term groundwater monitoring network and for the sustainable management of groundwater resources. This study relies mostly on the compilation of existing data, but additional field work has also been carried out, allowing for the first time in the Magdalen Islands, direct observation of the depth and shape of the transition zone between freshwater and seawater under natural conditions. Simulations were conducted along a 2D cross-section on Grande Entrée Island in order to assess the individual and combined impacts of sea-level rise, coastal erosion and decreased groundwater recharge on the position of the saltwater–freshwater interface. The simulations were performed considering variable-density flow and solute transport under saturated-unsaturated conditions. The model was driven by observed and projected climate change scenarios to 2040 for the Magdalen Islands. New hydrological insights for the region: The simulation results show that among the three impacts considered, the most important is sea-level rise, followed by decreasing groundwater recharge and coastal erosion. When combined, these impacts cause the saltwater–freshwater interface to migrate inland over a distance of 37 m and to rise by 6.5 m near the coast to 3.1 m further inland, over a 28-year period.

Mercury is a pervasive environmental contaminant, the anthropogenic portion of which is increasing globally, and in northeastern North America in particular. Seabirds frequently are used as indicators of the marine environment, including mercury contamination. We analysed paired samples for total mercury (Hg) concentrations in feathers and blood from adult and chick, albumen, and lipid-free yolk of seven seabirds breeding on Machias Seal Island, New Brunswick, Canada - Arctic Tern (Sterna paradisaea), Atlantic Puffin (Fratercula arctica), Common Eider (Somateria mollissima), Common Murre (Uria aalge), Common Tern (Sterna hirundo), Leach's Storm-petrel (Oceanodroma leucorhoa), and Razorbill (Alca torda). We also used stable-isotope ratios of carbon ({delta}{sup 13}C), and nitrogen ({delta}{sup 15}N) to evaluate the relationship between carbon source and trophic position and mercury. We found high Hg concentrations across tissue types in Leach's Storm-petrels, and Razorbills, with lower concentrations in other species, the lowest being in Common Eiders. Storm-petrels prey on mesopelagic fish that accumulate mercury, and Razorbills feed on larger, older fish that bioaccumulate heavy metals. Biomagnification of Hg, or the increase in Hg concentration with trophic position as measured by {delta}{sup 15}N, was significant and greater in albumen than other tissues, whereas in other tissues, {delta}{sup 15}N explained little of the overall variation in Hg concentration. Hg concentrations in egg components are higher on Machias Seal Island than other sites globally and in the Gulf of Maine region, but only for some species. Further detailed investigations are required to determine the cause of this trend.

Status of endangered and threatened caribou on Canada's arctic islands

Directory of Open Access Journals (Sweden)

Anne Gunn

2000-04-01

Full Text Available Caribou (Rangifer tarandus on the Canadian Arctic Islands occur as several populations which are nationally classified as either endangered or threatened. On the western High Arctic (Queen Elizabeth Islands, Peary caribou (R. t. pearyi declined to an estimated 1100 caribou in 1997. This is the lowest recorded abundance since the first aerial survey in 1961 when a high of ca. 24 363 caribou was estimated on those islands. Peary caribou abundance on the eastern Queen Elizabeth Islands is almost unknown. On the southern Arctic Islands, three caribou populations declined by 95-98% between 1973 and 1994 but our information is unclear about the numerical trends for the two other populations. Diagnosis of factors driving the declines is complicated by incomplete information but also because the agents driving the declines vary among the Arctic's different climatic regions. The available evidence indicates that severe winters caused Peary caribou die-offs on the western Queen Elizabeth Islands. On Banks Island, harvesting together with unfavourable snow/ice conditions in some years accelerated the decline. On northwestern Victoria Island, harvesting apparently explains the decline. The role of wolf predation is unknown on Banks and notthwest Victoria islands, although wolf sightings increased during the catibou declines. Reasons for the virtual disappearance of arctic-island caribou on Prince of Wales and Somerset islands are uncertain. Recovery actions have started with Inuit and Inuvialuit reducing their harvesting but it is too soon to evaluate the effect of those changes. Recovery of Peary caribou on the western Queen Elizabeth Islands is uncertain if the current trends toward warmer temperatures and higher snowfall persist.

Recommendation of federal protected area designation for Sable Island

Energy Technology Data Exchange (ETDEWEB)

NONE

2010-04-15

A report by the Canada - Nova Scotia Sable Island Task Group (TG) and its partners recommends the appropriate federal protected area designation for Sable Island as being either that of a national wildlife area or of a national park, and includes objectives and a synopsis of the analyses of the designation options. It was found that both protected area designations are feasible and would ensure equivalent and comprehensive conservation of the ecology and wildlife on the Island, including the horses, but the TG's preferred recommendation is the designation of Sable Island as a National Park under the Canada National Parks Act. The next steps include consultations and a review of the issues identified during these consultations to facilitate the designation.

TOXICanada: 13 good reasons to establish a Clean Canada Fund

2001-07-01

Contaminated sites abound in Canada, including industrial sites in cities, abandoned hazardous waste dumps, old DEW line sites, landfills, nuclear power plants, mines sites and tailings ponds. There is no inventory of these sites, but an estimated 5,000 of them are on federally-owned lands. The environmental effects of these sites are only guessed at, but it is safe to say that they endanger the health of present and future generations of Canadians, particularly children and other vulnerable populations living in communities affected by these toxins. This report attempts to focus attention on the dangers inherent in untreated contaminated sites by highlighting one contaminated sites per province and territory that represent a range of the most common types of contaminated sites that Canada will, sooner or later, have to deal with. The report also urges the establishment of a Clean Canada Fund to deal with these contaminated sites, starting with an inventory, followed by an immediate start to clean up priority contaminated sites, and relocate communities at risk. The 13 sites highlighted are : Argentia (Newfoundland -- PCBs left by the Americans when they abandoned a 3,600 hectare naval base after 50 years); Sleepy Hollow Landfill in Queens County (Prince Edward Island -- mercury and fly ash pollution from an incinerator site); Sidney Tar Ponds (Nova Scotia --the largest toxic waste site in North America, site of a former steel mill, contaminated by PCBs and other deadly chemicals); Miramichi River (New Brunswick -- 20,000 tonnes of toxic creosote, and pentachlorophenol dumped into the river, left over from a wood preserving operation and base metals from a base metal mining operation which dumped millions of gallons of water carrying base metals which eventually deposited in the Miramichi); Technoparc (Quebec -- hydrocarbons and toxic wastes, including PCBs, from an old landfill site near Montreal); Beckwith Township (Ontario -- groundwater contaminated with

The palaeobiology of high latitude birds from the early Eocene greenhouse of Ellesmere Island, Arctic Canada.

Fossils attributable to the extinct waterfowl clade Presbyornithidae and the large flightless Gastornithidae from the early Eocene (~52-53 Ma) of Ellesmere Island, in northernmost Canada are the oldest Cenozoic avian fossils from the Arctic. Except for its slightly larger size, the Arctic presbyornithid humerus is not distinguishable from fossils of Presbyornis pervetus from the western United States, and the Gastornis phalanx is within the known size range of mid-latitude individuals. The occurrence of Presbyornis above the Arctic Circle in the Eocene could be the result of annual migration like that of its living duck and geese relatives, or it may have been a year-round resident similar to some Eocene mammals on Ellesmere and some extant species of sea ducks. Gastornis, along with some of the mammalian and reptilian members of the Eocene Arctic fauna, likely over-wintered in the Arctic. Despite the milder (above freezing) Eocene climate on Ellesmere Island, prolonged periods of darkness occurred during the winter. Presence of these extinct birds at both mid and high latitudes on the northern continents provides evidence that future increases in climatic warming (closer to Eocene levels) could lead to the establishment of new migratory or resident populations within the Arctic Circle.

Eastern Canada natural gas developments

2001-01-01

This power point presentation addressed the following topics regarding development of natural gas in eastern Canada: (1) the 18 Tcf of proven natural gas reserves at Sable Island, (2) Canadian markets benefiting from the Maritimes and Northeast Pipeline (M and NP), (3) a 20 year franchise agreement between Enbridge Gas and the government of New Brunswick, (4) the 25 year provincial franchise agreement by Sempra Atlantic Gas, and (5) Sable Island's influence on central Canada. The Sable Offshore Energy Project (SOEP) is now producing about 540,000 MMBtu/day from 6 fields. Plans for Tier 2 expansion are underway. Firm contracts for the M and NP are scheduled to transport gas from the SOEP to markets in Nova Scotia, New Brunswick, Maine and New Hampshire. Sable gas is also a potential supply for the Quebec market. Gaz Metropolitain and Enbridge have proposed to build the Cartier Pipeline from the Quebec/New Brunswick border to Quebec City. It is unlikely that Sable Island supply will directly serve the Ontario market. Canadian customers for Sable gas and M and NP service include pulp and paper companies, oil refineries, power generators and local distribution companies (LDC), with the majority of demand coming form the electric power industry. tabs., figs

Whether in Homer or Plato, Shakespeare or Huxley, throughout history, thinking about islands has shaped how we think about human nature and our place in the world.

Gender-Based Experiences and Perceptions after the 2010 Winter Storms in Atlantic Canada

Directory of Open Access Journals (Sweden)

Liette Vasseur

2015-10-01

Full Text Available This paper conveys the findings of the first phase of a longitudinal study into climate change adaptation in Atlantic Canada. Men and women from 10 coastal communities in three provinces (Quebec, New Brunswick, and Prince Edward Island were interviewed to better understand how both sexes perceived and reacted to extreme weather events. Their responses were recorded based on their experiences, personal and community levels of preparedness, as well as help received and effects on their lives. Most importantly, the findings denote that more men were personally prepared and more active in the community than women. More men recognized a deficiency in help at the community level, and were critical of government in particular, addressing a lack of financial interventions and support. Women were forthcoming with their emotions, admitting to feeling fear and worry, and their perceptions in terms of impacts and actions were closer to home. The results support what others have shown that in rural and coastal communities the traditional division of labor may influence and lead to a gender bias in terms of actions and gradual adaptation in communities. There is a need to better understand how these sometimes subtle differences may affect decisions that do not always consider women’s roles and experiences in the face of extreme events.

Glacially-megalineated limestone terrain of Anticosti Island, Gulf of St. Lawrence, Canada; onset zone of the Laurentian Channel Ice Stream

Science.gov (United States)

Eyles, Nick; Putkinen, Niko

2014-03-01

Anticosti is a large elongate island (240 km long, 60 km wide) in eastern Canada within the northern part of a deep water trough (Gulf of St. Lawrence) that terminates at the Atlantic continental shelf edge. The island's Pleistocene glaciological significance is that its long axis lay transverse to ice from the Quebec and Labrador sectors of the Laurentide Ice Sheet moving south from the relatively high-standing Canadian Shield. Recent glaciological reconstructions place a fast-flowing ice stream along the axis of the Gulf of St. Lawrence but supporting geologic evidence in terms of recognizing its hard-bedded onset zone and downstream streamlined soft bed is limited. Anticosti Island consists of gently southward-dipping limestone plains composed of Ordovician and Silurian limestones (Vaureal, Becscie and Jupiter formations) with north-facing escarpments transverse to regional ice flow. Glacial deposits are largely absent and limestone plains in the higher central plateau of the island retain a relict apparently ‘preglacial’ drainage system consisting of deeply-incised dendritic bedrock valleys. In contrast, the bedrock geomorphology of the lower lying western and eastern limestone plains of the island is strikingly different having been extensively modified by glacial erosion. Escarpments are glacially megalineated with a distinct ‘zig-zag’ planform reflecting northward-projecting bullet-shaped ‘noses’ (identified as rock drumlins) up to 2 km wide at their base and 4 km in length with rare megagrooved upper surfaces. Drumlins are separated by southward-closing, funnel-shaped ‘through valleys’ where former dendritic valleys have been extensively altered by the streaming of basal ice through gaps in the escarpments. Glacially-megalineated bedrock terrain such as on the western and eastern flanks of Anticosti Island is elsewhere associated with the hard-bedded onset zones of fast flowing ice streams and provides important ground truth for the

Hartman, C. Alex; Ackerman, Joshua T.; Herzog, Mark P.; Strong, Cheryl; Trachtenbarg, David; Shore, Crystal A.

2017-05-08

Executive SummaryIn order to address the 2008/10 and Supplemental 2014 NOAA Fisheries Biological Opinion for operation of the Federal Columbia River Power System, the U.S. Army Corps of Engineers (USACE) and the Bureau of Reclamation (Reclamation) developed and have begun implementation of Caspian tern (Hydroprogne caspia) management plans. This implementation includes redistribution of the Caspian terns in the Columbia River estuary and the mid-Columbia River region to reduce predation on salmonids listed under the Endangered Species Act. Key elements of the plans include (1) reducing nesting habitat for Caspian terns in the Columbia River estuary and the mid-Columbia River region, and (2) creating or modifying nesting habitat at alternative sites within the Caspian tern breeding range. USACE and Reclamation developed Caspian tern nesting habitat at the U.S. Fish and Wildlife Service Don Edwards San Francisco Bay National Wildlife Refuge (DENWR), California, prior to the 2015 nesting season. Furthermore, to reduce or eliminate potential conflicts between nesting Caspian terns and threatened western snowy plovers (Charadrius alexandrinus nivosus), nesting habitat for snowy plovers also was developed. Seven recently constructed islands within two managed ponds (Ponds A16 and SF2) of DENWR were modified to provide habitat attractive to nesting Caspian terns (5 islands) and snowy plovers (2 islands). These 7 islands were a subset of 46 islands recently constructed in Ponds A16 and SF2 to provide waterbird nesting habitat as part of the South Bay Salt Pond (SBSP) Restoration Project.We used social attraction methods (decoys and electronic call systems) to attract Caspian terns and snowy plovers to these seven modified islands, and conducted surveys between March and September of 2015 and 2016 to evaluate nest numbers, nest density, and productivity. Results from the 2015 nesting season, the first year of the study, indicated that island modifications and social

Intensive farming of potatoes in Prince Edward Island (PEI) relies on the repeated and widespread application of fertilizers and pesticides. In PEI the main potato farming areas are in close proximity and drain directly to estuaries. Runoff from high agricultural activity watersheds could impact benthic organism health in the depositional zone of downstream estuaries. The estuarine filter feeder Mya arenaria (soft-shell clam) could be particularly vulnerable to both particle-adsorbed and water soluble contaminants. M. arenaria is susceptible to haemocytic leukemia. In May 2009, we established that heavily proliferated leukemia (HPL) prevalence was generally higher in PEI estuaries located downstream of high intensity potato farming (Dunk and Wilmot estuaries) watersheds than in estuaries downstream of lower intensity areas. Using Mab-1E10 based immunocytochemistry we observed that leukemic haemocytes from the Dunk and Wilmot estuaries were 1E10 negative whereas those from the Ox/Sheep estuary (low potato farming intensity) were 1E10 positive. The expression of genes in the p53 tumour suppressor pathway enabled us to differentiate groups of leukemic and normal M. arenaria, validating our diagnoses. In October 2009, we confirmed that HPL prevalence was elevated in the Dunk and Wilmot estuaries compared to reference (Souris River). Moreover, leukemia prevalence declined with distance from the river mouths along transects through the Dunk and Wilmot estuaries. The pesticides ß-endosulfan and α-endosulfan were detected in surface sediments from the Dunk and Wilmot estuaries, but not in sediments from either the Souris River or several other lower intensity potato farming watersheds. Our study provides evidence of an association between intensity of potato farming and prevalence of clam leukemia at downstream estuaries in PEI. - Highlights: ► We examined leukemia prevalence in PEI clams Mya arenaria. ► Prevalence was generally higher downstream of high intensity

Eastern Canadian crude oil supply and its implications for regional energy security

International Nuclear Information System (INIS)

Hughes, Larry

2010-01-01

Canada has been blessed with immense energy resources; however, their distribution is not uniform. One such example is crude oil, which is found primarily in western Canada. Eastern Canada, consisting of the six eastern-most provinces (Newfoundland and Labrador, New Brunswick, Nova Scotia, Ontario, Prince Edward Island, and Quebec), produce limited quantities of crude oil, most of which is exported to the United States. Ideally, western Canadian crude oil would meet the demands of eastern Canada; however, the North American Free Trade Agreement (NAFTA) and the absence of oil pipelines means that eastern Canada increasingly relies on supplies of crude oil from a small number of oil exporting countries, many with declining production. This paper examines crude oil production, supply, and its refining in eastern Canada. It shows that crude production in the region has reached its peak and that increasing global competition for crude oil will affect energy security in eastern Canada, either through price increases or supply shortages, or both.

Defining historical baselines for conservation: ecological changes since European settlement on Vancouver Island, Canada.

Science.gov (United States)

Bjorkman, Anne D; Vellend, Mark

2010-12-01

Conservation and restoration goals are often defined by historical baseline conditions that occurred prior to a particular period of human disturbance, such as European settlement in North America. Nevertheless, if ecosystems were heavily influenced by native peoples prior to European settlement, conservation efforts may require active management rather than simple removal of or reductions in recent forms of disturbance. We used pre-European settlement land survey records (1859-1874) and contemporary vegetation surveys to assess changes over the past 150 years in tree species and habitat composition, forest density, and tree size structure on southern Vancouver Island and Saltspring Island, British Columbia, Canada. Several lines of evidence support the hypothesis that frequent historical burning by native peoples, and subsequent fire suppression, have played dominant roles in shaping this landscape. First, the relative frequency of fire-sensitive species (e.g., cedar [Thuja plicata]) has increased, whereas fire-tolerant species (e.g., Douglas-fir [Pseudotsuga menziesii]) have decreased. Tree density has increased 2-fold, and the proportion of the landscape in forest has greatly increased at the expense of open habitats (plains, savannas), which today contain most of the region's threatened species. Finally, the frequency distribution of tree size has shifted from unimodal to monotonically decreasing, which suggests removal of an important barrier to tree recruitment. In addition, although most of the open habitats are associated with Garry oak (Quercus garryana) at present, most of the open habitats prior to European settlement were associated with Douglas-fir, which suggests that the current focus on Garry oak as a flagship for the many rare species in savannas may be misguided. Overall, our results indicate that the maintenance and restoration of open habitats will require active management and that historical records can provide critical guidance to such

First record of eocene bony fishes and crocodyliforms from Canada's Western Arctic.

2014-01-01

Discovery of Eocene non-marine vertebrates, including crocodylians, turtles, bony fishes, and mammals in Canada's High Arctic was a critical paleontological contribution of the last century because it indicated that this region of the Arctic had been mild, temperate, and ice-free during the early - middle Eocene (∼53-50 Ma), despite being well above the Arctic Circle. To date, these discoveries have been restricted to Canada's easternmost Arctic - Ellesmere and Axel Heiberg Islands (Nunavut). Although temporally correlative strata crop out over 1,000 km west, on Canada's westernmost Arctic Island - Banks Island, Northwest Territories - they have been interpreted as predominantly marine. We document the first Eocene bony fish and crocodyliform fossils from Banks Island. We describe fossils of bony fishes, including lepisosteid (Atractosteus), esocid (pike), and amiid, and a crocodyliform, from lower - middle Eocene strata of the Cyclic Member, Eureka Sound Formation within Aulavik National Park (∼76°N. paleolat.). Palynology suggests the sediments are late early to middle Eocene in age, and likely spanned the Early Eocene Climatic Optimum (EECO). These fossils extend the geographic range of Eocene Arctic lepisosteids, esocids, amiids, and crocodyliforms west by approximately 40° of longitude or ∼1100 km. The low diversity bony fish fauna, at least at the family level, is essentially identical on Ellesmere and Banks Islands, suggesting a pan-High Arctic bony fish fauna of relatively basal groups around the margin of the Eocene Arctic Ocean. From a paleoclimatic perspective, presence of a crocodyliform, gar and amiid fishes on northern Banks provides further evidence that mild, year-round temperatures extended across the Canadian Arctic during early - middle Eocene time. Additionally, the Banks Island crocodyliform is consistent with the phylogenetic hypothesis of a Paleogene divergence time between the two extant alligatorid lineages Alligator

Robinson was one of classical Hollywood’s most influential actors; for instance, traits of his portrayal of Little Caesar (one of the very first American gangster films can be found in almost all subsequent cinematic gangster figures, from Scarface to Vito Corleone. In the same vein, the doomed noir characters he played in Fritz Lang’s The Woman in the Window and Scarlet Street are still considered by film critics today to be some of the finest, most nuanced examples of noir heroes. Therefore, the main body of my article will be dedicated to a more detailed analysis of these films, while the introductory section will trace his biography and discuss some of his better-known films, such as Confessions of a Nazi Spy and Key Largo. The present study highlights Edward G. Robinson’s merits and impact on the cinema industry, proving that this diminutive Romanian Jew of humble origins was indeed something of a giant during Hollywood’s classical era.

Haemic neoplasia was first considered a disease of concern for soft-shell clams in Prince Edward Island (PEI) when it was diagnosed as the cause of mass mortalities in 1999. The aetiology of the disease remains elusive, but has been associated with environmental degradation. In this study, a 2-year (2001-2002) geographic and seasonal survey was conducted for haemic neoplasia, using histology, in soft-shell clams from PEI. In addition, using geographic information system, the association between anthropogenic factors in the watersheds at sites affected by haemic neoplasia and the prevalence of the disease was investigated. Finally, histopathological changes were assessed in soft-shell clams experimentally exposed to four concentrations of chlorothalonil for 27 days. Haemic neoplasia could not be induced at any concentration of chlorothalonil. Clams exposed to a concentration of 1000 μg L(-1) of the fungicide, however, exhibited an LC50 of 17 days. Although this information provides additional toxicity information (LC50) for soft-shell clams, further experiments are required to assess longer term exposure to the fungicide. The highest prevalences of haemic neoplasia in PEI were found in North River and Miscouche (28.3-50.9% and 33.0-77.8%, respectively). No clear seasonal patterns were found. There was a correlation between haemic neoplasia prevalence and watersheds with a high percentage of potato acreage and forest coverage (P = 0.026 and P = 0.045, respectively), suggesting a link between anthropogenic activity and the prevalence of the disease. © 2015 John Wiley & Sons Ltd.

Intensive farming of potatoes in Prince Edward Island (PEI) relies on the repeated and widespread application of fertilizers and pesticides. In PEI the main potato farming areas are in close proximity and drain directly to estuaries. Runoff from high agricultural activity watersheds could impact benthic organism health in the depositional zone of downstream estuaries. The estuarine filter feeder Mya arenaria (soft-shell clam) could be particularly vulnerable to both particle-adsorbed and water soluble contaminants. M. arenaria is susceptible to haemocytic leukemia. In May 2009, we established that heavily proliferated leukemia (HPL) prevalence was generally higher in PEI estuaries located downstream of high intensity potato farming (Dunk and Wilmot estuaries) watersheds than in estuaries downstream of lower intensity areas. Using Mab-1E10 based immunocytochemistry we observed that leukemic haemocytes from the Dunk and Wilmot estuaries were 1E10 negative whereas those from the Ox/Sheep estuary (low potato farming intensity) were 1E10 positive. The expression of genes in the p53 tumour suppressor pathway enabled us to differentiate groups of leukemic and normal M. arenaria, validating our diagnoses. In October 2009, we confirmed that HPL prevalence was elevated in the Dunk and Wilmot estuaries compared to reference (Souris River). Moreover, leukemia prevalence declined with distance from the river mouths along transects through the Dunk and Wilmot estuaries. The pesticides ss-endosulfan and {alpha}-endosulfan were detected in surface sediments from the Dunk and Wilmot estuaries, but not in sediments from either the Souris River or several other lower intensity potato farming watersheds. Our study provides evidence of an association between intensity of potato farming and prevalence of clam leukemia at downstream estuaries in PEI. - Highlights: Black-Right-Pointing-Pointer We examined leukemia prevalence in PEI clams Mya arenaria.

To evaluate the current status of interventional radiology in Canada. A questionnaire was sent to 28 Canadian interventional radiologists (defined as a physician who performs any type of interventional procedure, including biopsies, but excluding interventional neuroradiology) practising in both tertiary and community hospitals in the major centres in all provinces except Prince Edward Island. Twenty-two (79%) of 28 surveys were completed and returned, providing data about 86 interventional radiologists (IRs). IRs were performing almost all of the following procedures at their institutions: inferior vena cava filter placement, venous angioplasty, dialysis fistula angioplasty, diagnostic and therapeutic pulmonary and bronchial artery procedures, diagnostic and therapeutic procedures of the lower extremity and renal arteries, percutaneous abscess and biliary drainage procedures, percutaneous nephrostomy, and fibroid embolization. A second group of procedures, performed by both IRs and non-radiologists in most institutions, included: all types of central venous catheter placements, pleural drainage, and gastrostomy tube placement. Procedures not being performed by anyone in a number of institutions included: dialysis graft thrombolysis, varicocele embolization, transjugular intrahepatic portosystemic shunts, palliative stenting of the gastrointestinal tract, fallopian tube recannalization, and liver and prostate tumour treatments. The factors most often limiting the respondents' ability to provide a comprehensive interventional service were the interventional radiology inventory budget and the availability of interventional radiology rooms; 50% of respondents indicated the number of available nurses, technologists and IRs was also an important limiting factor. IRs in Canada still play a major role in many of the most commonly performed procedures. However, limited availability of resources and personnel in many institutions may be hampering the ability of IRs to

International energy opportunities were reviewed, with emphasis on China, and on Canada-China Power Inc., alternatively known as 'Team Canada'. Canada-Chine Power Inc., is a company founded by three of Canada's leading engineering consulting firms, i.e., Monenco AGRA Inc., SNC Lavalin Inc., and Acres International Limited. An office was established in Beijing in January 1994. Other Canadian manufacturers and engineering companies also have been actively pursuing hydro power opportunities in China for several years in view of China's enormous demand for power. It was estimated that by the year 2000, China will install 137 GW of new capacity, and foreign investment will account for approximately a third of the growth. AGRA is working on a 5400 MW thermal plant on Hainan Island, and is in final negotiations with the Yangtze Three Gorges Development Corporation for a management information system for their 18200 MW multi-purpose project. Criteria used by AGRA to identify international opportunities include: (1) a large capital spending program in fields with capabilities, expertise and past experience, (2) access to international funding, (3) competitive Canadian technology, and (4) an acceptable business and cultural climate. In assessing the opportunities, AGRA decided to concentrate on providing technologies in greatest need, such as project management systems, computer engineering and CAD systems, and clean coal technology

The reticulating phylogeny of island biogeography theory.

Lomolino, Mark V; Brown, James H

2009-12-01

Biogeographers study all patterns in the geographic variation of life, from the spatial variation in genetic and physiological characteristics of cells and individuals, to the diversity and dynamics of biological communities among continental biotas or across oceanic archipelagoes. The field of island biogeography, in particular, has provided some genuinely transformative insights for the biological sciences, especially ecology and evolutionary biology. Our purpose here is to review the historical development of island biogeography theory during the 20th century by identifying the common threads that run through four sets of contributions made during this period, including those by Eugene Gordon Munroe (1948, 1953), Edward O. Wilson (1959, 1961), Frank W. Preston (1962a,b), and the seminal collaborations between Wilson and Robert H. MacArthur (1963, 1967), which revolutionized the field and served as its paradigm for nearly four decades. This epistemological account not only reviews the intriguing history of island theory, but it also includes fundamental lessons for advancing science through transformative integrations. Indeed, as is likely the case with many disciplines, island theory advanced not as a simple accumulation of facts and an orderly succession of theories and paradigms, but rather in fits and starts through a reticulating phylogeny of ideas and alternating periods of specialization and reintegration. We conclude this review with a summary of the salient features of this scientific revolution in the contest of Kuhn's structure, which strongly influenced theoretical advances during this period, and we then describe some of the fundamental assumptions and tenets of an emerging reintegration of island biogeography theory.

The stratigraphic imprint of a mid-Telychian (Llandovery, Early Silurian glaciation on far-field shallow-water carbonates, Anticosti Island, Eastern Canada

Directory of Open Access Journals (Sweden)

François Clayer

2014-12-01

Full Text Available The near-field stratigraphic record of the Early Silurian glaciations is well documented in the literature. Data from far-field areas are, however, sparse. One of the best far-field stratigraphic records of these Llandovery glaciations is exposed on Anticosti Island in eastern Canada. Eight shallow-water paleotropical facies are present close to the mid-Telychian Jupiter–Chicotte formational boundary along the south-central coast of Anticosti Island. These can be grouped into three facies associations that include, from bottom to top: a carbonate facies association (FA-1, a mixed siliciclastic and carbonate facies association (FA-2 and an encrinitic facies association (FA-3. These mid- to outer-ramp strata represent deposition mostly from episodic, high-energy storm events as evidenced by their sharp bases, hummocky cross-stratification, large wave ripples, gutter casts and wave-enhanced sediment gravity flow deposits. Superimposed on a long-term regressive trend, one main transgressive–regressive (TR sequence and four meter-scale TR cycles are evident, indicating a multi-order stratigraphic framework developed under the influence of glacio-eustasy. The Jupiter–Chicotte formational boundary, a regional discontinuity surface caused by a forced regression, corresponds to the onset of a far-field mid-Telychian glaciation.

Simulation of groundwater flow in the Edwards-Trinity and related aquifers in the Pecos County region, Texas

The Edwards-Trinity aquifer is a vital groundwater resource for agricultural, industrial, and public supply uses in the Pecos County region of western Texas. The U.S. Geological Survey completed a comprehensive, integrated analysis of available hydrogeologic data to develop a numerical groundwater-flow model of the Edwards-Trinity and related aquifers in the study area in parts of Brewster, Jeff Davis, Pecos, and Reeves Counties. The active model area covers about 3,400 square miles of the Pecos County region of Texas west of the Pecos River, and its boundaries were defined to include the saturated areas of the Edwards-Trinity aquifer. The model is a five-layer representation of the Pecos Valley, Edwards-Trinity, Dockum, and Rustler aquifers. The Pecos Valley aquifer is referred to as the alluvial layer, and the Edwards-Trinity aquifer is divided into layers representing the Edwards part of the Edwards-Trinity aquifer and the Trinity part of the Edwards-Trinity aquifer, respectively. The calibration period of the simulation extends from 1940 to 2010. Simulated hydraulic heads generally were in good agreement with observed values; 1,684 out of 2,860 (59 percent) of the simulated values were within 25 feet of the observed value. The average root mean square error value of hydraulic head for the Edwards-Trinity aquifer was 34.2 feet, which was approximately 4 percent of the average total observed change in groundwater-level altitude (groundwater level). Simulated spring flow representing Comanche Springs exhibits a pattern similar to observed spring flow. Independent geochemical modeling corroborates results of simulated groundwater flow that indicates groundwater in the Edwards-Trinity aquifer in the Leon-Belding and Fort Stockton areas is a mixture of recharge from the Barilla and Davis Mountains and groundwater that has upwelled from the Rustler aquifer.

Understanding the implications of climate change on northern Canada requires a background about the size and diversity of its human and biogeophysical systems. Occupying an area of almost 40% of Canada, with one-third of this contained in Arctic islands, Canada's northern territories consist of a diversity of physical environments unrivaled around the circumpolar north. Major ecozones composed of a range of landforms, climate, vegetation, and wildlife include: Arctic, boreal and taiga cordillera; boreal and taiga plains; taiga shield; and northern and southern Arctic. Although generally characterized by a cold climate, there is an enormous range in air temperature with mean annual values being as high as -5 deg C in the south to as low as -20 deg C in the high Arctic islands. A similar contrast characterizes precipitation, which can be >700 mm y-1 in some southern alpine regions to as low as 50 mm y-1 over islands of the high Arctic. Major freshwater resources are found within most northern ecozones, varying from large glaciers or ice caps and lakes to extensive wetlands and peat lands. Most of the North's renewable water, however, is found within its major river networks and originates in more southerly headwaters. Ice covers characterize the freshwater systems for multiple months of the year while permafrost prevails in various forms, dominating the terrestrial landscape. The marine environment, which envelops the Canadian Arctic Archipelago, is dominated by seasonal to multiyear sea ice often several meters thick that plays a key role in the regional climate. Almost two-thirds of northern Canadian communities are located along coastlines with the entire population being just over 100 000. Most recent population growth has been dominated by an expansion of nonaboriginals, primarily the result of resource development and the growth of public administration. The economies of northern communities, however, remain quite mixed with traditional land

Kataoka, Tomoya; Murray, Cathryn Clarke; Isobe, Atsuhiko

2017-09-12

The abundance of marine macro-debris was quantified with high spatial resolution by applying an image processing technique to archived shoreline aerial photographs taken over Vancouver Island, Canada. The photographs taken from an airplane at oblique angles were processed by projective transformation for georeferencing, where five reference points were defined by comparing aerial photographs with satellite images of Google Earth. Thereafter, pixels of marine debris were extracted based on their color differences from the background beaches. The debris abundance can be evaluated by the ratio of an area covered by marine debris to that of the beach (percent cover). The horizontal distribution of percent cover of marine debris was successfully computed from 167 aerial photographs and was significantly related to offshore Ekman flows and winds (leeway drift and Stokes drift). Therefore, the estimated percent cover is useful information to determine priority sites for mitigating adverse impacts across broad areas. Copyright © 2017 Elsevier Ltd. All rights reserved.

Performance reporting in primary health care in Canada is challenging because of the dearth of concise and synthesized information. The paucity of information occurs, in part, because the majority of primary health care in Canada is delivered through a multitude of privately owned small businesses with no mechanism or incentives to provide information about their performance. The purpose of this paper is to report the methods used to recruit family physicians and their patients across 10 provinces to provide self-reported information about primary care and how this information could be used in recruitment and data collection for future large scale pan-Canadian and other cross-country studies. Canada participated in an international large scale study-the QUALICO-PC (Quality and Costs of Primary Care) study. A set of four surveys, designed to collect in-depth information regarding primary care activities was collected from: practices, providers, and patients (experiences and values). Invitations (telephone, electronic or mailed) were sent to family physicians. Eligible participants were sent a package of surveys. Provincial teams kept records on the number of: invitation emails/letters sent, physicians who registered, practices that were sent surveys, and practices returning completed surveys. Response and cooperation rates were calculated. Invitations to participate were sent to approximately 23,000 family physicians across Canada. A total of 792 physicians and 8,332 patients from 772 primary care practices completed the surveys, including 1,160 participants completing a Patient Values survey and 7,172 participants completing a Patient Experience survey. Overall, the response rate was very low ranging from 2% (British Columbia) to 21% (Nova Scotia). However, the participation rate was high, ranging from 72% (Ontario) to 100% (New Brunswick/Prince Edward Island and Newfoundland & Labrador). The difficulties obtaining acceptable response rates by family physicians for

We have performed phase equilibrium experiments to determine the pre-eruptive conditions of the largest phonolitic caldera-forming eruption (∼20 km3 of DRE) that occurred on Tenerife (Canary Islands). The Abrigo ignimbrite was erupted during the last caldera-forming episode (ca. 190 ka), from the Canadas caldera. Comparison of the natural and experimental phase proportions and compositions indicates that the phonolite at the roof of the Abrigo magma reservoir was at 130 ± 50 MPa (corresponding to ca. 4 - 5 km below the surface), 825 ± 25 oC, with 3 ± 1 wt% dissolved H2O and fO2 at the Ni-NiO buffer ? 1 log unit. This shows that the magma that produced the largest ignimbrite on Tenerife was stored at relatively shallow depths but was water-undersaturated, and its eruption was probably triggered by input of fresh mafic magma.

Quantification of tsunami hazard on Canada's Pacific Coast; implications for risk assessment

Science.gov (United States)

Evans, Stephen G.; Delaney, Keith B.

2015-04-01

Our assessment of tsunami hazard on Canada's Pacific Coast (i.e., the coast of British Columbia) begins with a review of the 1964 tsunami generated by The Great Alaska Earthquake (M9.2) that resulted in significant damage to coastal communities and infrastructure. In particular, the tsunami waves swept up inlets on the west coast of Vancouver Island and damaged several communities; Port Alberni suffered upwards of 5M worth of damage. At Port Alberni, the maximum tsunami wave height was estimated at 8.2 m above mean sea level and was recorded on the stream gauge on the Somass River located at about 7 m a.s.l, 6 km upstream from its mouth. The highest wave (9.75 m above tidal datum) was reported from Shields Bay, Graham Island, Queen Charlotte Islands (Haida Gwaii). In addition, the 1964 tsunami was recorded on tide gauges at a number of locations on the BC coast. The 1964 signal and the magnitude and frequency of traces of other historical Pacific tsunamis (both far-field and local) are analysed in the Tofino tide gauge records and compared to tsunami traces in other tide gauges in the Pacific Basin (e.g., Miyako, Japan). Together with a review of the geological evidence for tsunami occurrence along Vancouver Island's west coast, we use this tide gauge data to develop a quantitative framework for tsunami hazard on Canada's Pacific coast. In larger time scales, tsunamis are a major component of the hazard from Cascadia megathrust events. From sedimentological evidence and seismological considerations, the recurrence interval of megathrust events on the Cascadia Subduction Zone has been estimated by others at roughly 500 years. We assume that the hazard associated with a high-magnitude destructive tsunami thus has an annual frequency of roughly 1/500. Compared to other major natural hazards in western Canada this represents a very high annual probability of potentially destructive hazard that, in some coastal communities, translates into high levels of local risk

Relative sea-level changes and glacio-isostatic adjustment on the Magdalen Islands archipelago (Atlantic Canada) from MIS 5 to the late Holocene

The Magdalen Islands (Québec, Canada) in the centre of the Gulf of St. Lawrence are located in a strategic position for providing an overview of the relative sea-level (RSL) history of the Maritime Provinces of eastern Canada. Although data are available for the coastal terrestrial areas of the Maritimes, data from the Gulf are very scarce and both the RSL and glacio-isostatic adjustment (GIA) models extrapolate for this central region. This study provides new stratigraphic and chronological data from four outcrops and two coring sites on the Magdalen Islands. In addition to the five samples used mainly for age control purposes, nine new luminescence ages are presented. With these new data added to the available literature, a new RSL curve is reconstructed for the LGM to the late Holocene period and a partial curve is proposed for the interval between the late MIS 4 to the MIS 3. Data also indicate a few insights for the MIS 5 period. Results reveal that for the LGM to the late Holocene, the curve corresponds to the J-shaped curve scenario recognized in the literature. The RSL changes during this period are the result of glacio-isostatic rebound, migration and collapse of the peripheral forebulge, and eustatic sea-level changes. For the LGM to the early Holocene, glacio-isostatic depression curves displaying a few local differences are also proposed. For the late Holocene, the data constrain the curve between two types of indicators, i.e. marine and terrestrial, and indicate that the RSL has risen at least 3 m during the last two millennia. Sediments dated to the MIS 5 and the interval between the late MIS 4 and the MIS 3 illustrate that the GIA following the LGM also occurred for the MIS 5 interglacial and the MIS 3 interstadial. Finally, recent GIA models are discussed in light of the results of this paper.

From Early Exploration to Space Weather Forecasts: Canada's Geomagnetic Odyssey

Science.gov (United States)

Lam, Hing-Lan

2011-05-01

Canada is a region ideally suited for the study of space weather: The north magnetic pole is encompassed within its territory, and the auroral oval traverses its vast landmass from east to west. Magnetic field lines link the country directly to the outer magnetosphere. In light of this geographic suitability, it has been a Canadian tradition to install ground monitors to remotely sense the space above Canadian territory. The beginning of this tradition dates back to 1840, when Edward Sabine, a key figure in the “magnetic crusade” to establish magnetic observatories throughout the British Empire in the nineteenth century, founded the first Canadian magnetic observatory on what is now the campus of the University of Toronto, 27 years before the birth of Canada. This observatory, which later became the Toronto Magnetic and Meteorological Observatory, marked the beginning of the Canadian heritage of installing magnetic stations and other ground instruments in the years to come. This extensive network of ground-based measurement devices, coupled with space-based measurements in more modern times, has enabled Canadian researchers to contribute significantly to studies related to space weather.

PBO Borehole Strainmeters: 2017 Episodic Tremor and Slip Event for Southern Vancouver Island, BC, Canada through Olympia, WA, USA

The Plate Boundary Observatory's (PBO) borehole strainmeters along the Cascadia Subduction Zone (CSZ) record the development and migration of Episodic Tremor and Slip (ETS). Along the southern Vancouver Island to Olympia, WA portion of the CSZ ETS events seem to repeat every 14 months. ETS events are non-volcanic tremor swarms that occur over periods of weeks, often migrating along segments of the subduction zone and can release the energy equivalent to a M7 or greater earthquake. Each ETS event is different; initial propagation location, ETS movement, duration, and direction all vary. Constraints provided by strainmeter observations of ETS events illuminate strain release patterns along the subducting slab interface and may help resolve questions regarding the location of the locked zone of the slab and what role ETS events play in the CSZ earthquake cycle. The 2017 CSZ ETS began in early February continuing through early April. Beginning in the northern Olympic Peninsula, near Port Angeles, it migrated south towards Olympia over the course of a week. After a two week pause it resumed under the Straits of Juan de Fuca and propagated northwest under Vancouver Island. There are 15 PBO borehole strainmeters along this segment, and ETS strain observations correlate with seismic and GPS measurements. The PBO borehole strainmeters are sensitive even over great distances from the ETS epicenters, and observe compression or extension relative to the ETS migration. Openly available PBO borehole strainmeter data used by the community has made significant contributions to understanding the ETS process, including the determination that ETS slip is tidally modulated. Data are publically available through UNAVCO and IRIS, which provide links to online tutorials and scripts. There are 32 strainmeters covering the CSZ from southern Vancouver Island, Canada to northern California, USA, and data spans back to 2005. Each site has a Gladwin tensor borehole strainmeter, a Malin three

Radionuclides in Canada goose eggs

Rickard, W.H.; Sweany, H.A.

1975-01-01

Low levels of radionuclides were measured in Canada goose eggs taken from deserted nests from Columbia River islands on the Energy Research and Development Administration's Hanford Reservation. Potassium-40, a naturally occurring radionuclide, was the most abundant radionuclide measured in egg contents and egg shell. Strontium-90 was incorporated into egg shells and cesium-137 into inner egg contents. Manganese-54, cobalt-60, and zinc-65 were more abundant in inner egg contents than in egg shell. Cerium-144 was detected in egg shell but not in inner shell

Strontium-90 in Canada goose eggshells: Nonfatal monitoring for contamination in wildlife

International Nuclear Information System (INIS)

Rickard, W.H.; Eberhardt, L.E.

1990-01-01

90 Sr was measured in eggshells from Canada geese (Branta canadensis moffitti) that nested on Columbia River islands up- and downstream from deactivated plutonium production reactors on the U.S. Department of Energy's Hanford Site in southeastern Washington. We also measured 90 Sr in wing bones of goose carcasses. Background levels of 90 Sr were based on eggshells collected on an island upstream of the reactors. A few eggshells collected from nests on a single island downstream of the reactors had slightly higher than background levels of 90 Sr. This may have resulted from geese eating shoreline plants or crops irrigated with Columbia River water that contained 90 Sr released into the river through groundwater seepage

The Glacial and Relative Sea Level History of Southern Banks Island, NT, Canada

Science.gov (United States)

Vaughan, Jessica Megan

The mapping and dating of surficial glacial landforms and sediments across southern Banks Island document glaciation by the northwest Laurentide Ice Sheet (LIS) during the last glacial maximum. Geomorphic landforms confirm the operation of an ice stream at least 1000 m thick in Amundsen Gulf that was coalescent with thin, cold-based ice crossing the island's interior, both advancing offshore onto the polar continental shelf. Raised marine shorelines across western and southern Banks Island are barren, recording early withdrawal of the Amundsen Gulf Ice Stream prior to the resubmergence of Bering Strait and the re-entry of Pacific molluscs ~13,750 cal yr BP. This withdrawal resulted in a loss of ~60,000 km2 of ice --triggering drawdown from the primary northwest LIS divide and instigating changes in subsequent ice flow. The Jesse moraine belt on eastern Banks Island records a lateglacial stillstand and/or readvance of Laurentide ice in Prince of Wales Strait (13,750 -- 12,750 cal yr BP). Fossiliferous raised marine sediments that onlap the Jesse moraine belt constrain final deglaciation to ~12,600 cal yr BP, a minimum age for the breakup of the Amundsen Gulf Ice Stream. The investigation of a 30 m thick and 6 km wide stratigraphic sequence at Worth Point, southwest Banks Island, identifies an advance of the ancestral LIS during the Mid-Pleistocene (sensu lato), substantially diversifying the glacial record on Banks Island. Glacial ice emplaced during this advance has persisted through at least two glacial-interglacial cycles, demonstrating the resilience of circumpolar permafrost. Pervasive deformation of the stratigraphic sequence also records a detailed history of glaciotectonism in proglacial and subglacial settings that can result from interactions between cold-based ice and permafrost terrain. This newly recognized history rejects the long-established paleoenvironmental model of Worth Point that assumed a simple 'layer-cake' stratigraphy.

Coordination of geothermal research

Energy Technology Data Exchange (ETDEWEB)

Jessop, A.M.; Drury, M.J.

1983-01-01

Visits were made in 1983 to various investigators and institutions in Canada to examine developments in geothermal research. Proposals for drilling geothermal wells to provide hot water for heating at a college in Prince Edward Island were made. In Alberta, the first phase of a program examining the feasibility of mapping sedimentary geothermal reservoirs was discussed. Some sites for possible geothermal demonstration projects were identified. In British Columbia, discussions were held between BC Hydro and Energy, Mines and Resources Canada on the drilling of a research hole into the peak of a temperature anomaly in the Meager Creek Valley. The British Columbia government has offered blocks of land in the Mount Cayley volcanic complex for lease to develop geothermal resources. A list of papers of interest to the Canadian geothermal energy program is appended.

Island Movements: Thinking with the Archipelago

Directory of Open Access Journals (Sweden)

Jonathan Pugh

2013-05-01

Full Text Available Whether in Homer or Plato, Shakespeare or Huxley, throughout history, thinking about islands has shaped how we think about human nature and our place in the world. However, to date archipelagos have received far less attention. This is problematic because we live, increasingly, in a world of island-island movements and not static forms. Not only in the more obvious cases of the Caribbean, Hawaii or the Philippines but, as Stratford et al (2011 say, many ‘continental forms’ like Canada and Australia are in fact archipelagos composed of thousands of island movements. To this list we can add more manufactured archipelagos: wind turbine arrays, industrial oil and military constellations. The key question therefore arises: what does it mean to think with the archipelago? This paper argues firstly that archipelagic thinking denaturalizes the conceptual basis of space and place, and therefore engages ‘the spatial turn’ presently sweeping the social sciences and humanities. Secondly, such thinking highlights the trope of what I call ‘metamorphosis’, of the adaptation and transformation of material, cultural and political practices through island movements. In both cases, I argue that thinking with the archipelago requires an important shift in how we frame analysis and engagement.

Modelling Infectious Hematopoietic Necrosis Virus Dispersion from Marine Salmon Farms in the Discovery Islands, British Columbia, Canada.

Directory of Open Access Journals (Sweden)

Michael G G Foreman

Full Text Available Finite volume ocean circulation and particle tracking models are used to simulate water-borne transmission of infectious hematopoietic necrosis virus (IHNV among Atlantic salmon (Salmo salar farms in the Discovery Islands region of British Columbia, Canada. Historical simulations for April and July 2010 are carried out to demonstrate the seasonal impact of river discharge, wind, ultra-violet (UV radiation, and heat flux conditions on near-surface currents, viral dispersion and survival. Numerical particles released from infected farm fish in accordance with IHNV shedding rates estimated through laboratory experiments are dispersed by model oceanic flows. Viral particles are inactivated by ambient UV radiation levels and by the natural microbial community at rates derived through laboratory studies. Viral concentration maps showing temporal and spatial changes are produced and combined with lab-determined minimum infectious dosages to estimate the infective connectivity among farms. Results demonstrate that neighbouring naïve farms can become exposed to IHNV via water-borne transport from an IHNV diseased farm, with a higher risk in April than July, and that many events in the sequence of farm outbreaks in 2001-2002 are consistent with higher risks in our farm connectivity matrix. Applications to other diseases, transfers between farmed and wild fish, and the effect of vaccinations are also discussed.

MIO-PLIOCENE CRUSTACEANS FROM THE CANARY ISLANDS, SPAIN

Directory of Open Access Journals (Sweden)

JUAN FRANCISCO BETANCORT

2014-11-01

Full Text Available There are few previous references to fossil crustaceans for the Neogene marine layers of the Canary Islands (Spain. The Mio-Pliocene marine sedimentary layers in the eastern islands (Gran Canaria, Fuerteventura and Lanzarote were previously characterised by the presence of numerous fossil fauna, mainly anthozoans and molluscs, which correspond to an equatorial-typepalaeoclimate, warmer than the present climate. This Mio-Pliocene transition dated between 9.3 and 4.1 Ma. In this paper, 12 fossil crustacean taxa are identified and classified, including decapods and barnacles: Balanus concavus Bronn, 1831, Balanus spongicola Brown, 1827, Balanus perforatus Bruguière, 1789, Chenolobia testudinaria Linnè, 1767, Tetraclita cf. rubescens Darwin, 1854, Callianassa matsoni Rathbun, 1935, Callianassa sp., Upogebia sp, Eriphia aff. verrucosa (Forskal, 1775 , Maja sp., Scylla michelini Milne-Edwards, 1861 and Ocypode sp. Some of these taxa mean new references for the Atlantic islands and the North African Atlantic and definitely enlarge the palaeographic distribution of Neogene crustaceans beyond the Mediterranean region, extending it to the North Atlantic. Particularly significant are the presence of Tetraclita cf. rubescens ,this being the first reported fossil occurrence of this barnacle outside the North America Pacific coasts, and Chenolobia testudinaria , indicating for the first time the existence of marine turtles in these islands during the Neogene. These results are coherent with previous research hypothesising the existence of a flow of surface water between the Pacific and Atlantic in the Mio-Pliocene transition (Central American Seaway, CAS which explains the arrival of organisms, in larval stage, from Central America to the Canary Islands.

Full Text Available Marion Island, the larger of the Prince Edward Islands, lies in the sub-Antarctic biogeographic region in the southern Indian Ocean. From previous surveys, four spider species are known from Marion. The last survey was undertaken in 1968. During this study a survey was undertaken over a period of four weeks on the island to determine the present spider diversity and to record information about the habitat preferences and general behaviour of the species present. Three collection methods (active search, Tullgren funnels and pitfall traps were used, and spiders were sampled from six habitat sites. A total of 430 spiders represented by four families were collected, Myro kerguelenesis crozetensis Enderlein, 1909 and M. paucispinosus Berland, 1947 (Desidae, Prinerigone vagans (Audouin, 1826 (Linyphiidae, Cheiracanthium furculatum Karsch, 1879 (Miturgidae and an immature Salticidae. The miturgid and salticid are first records. Neomaso antarticus (Hickman, 1939 (Linyphiidae was absent from samples, confirming that the species might have been an erroneous record.

Feyz Kashani and Jonathan Edwards on the Place of Heart in Religious Knowledge

Directory of Open Access Journals (Sweden)

Saham Asadinia

2014-08-01

Full Text Available This essay seeks to summarize and compare the theological ideas of Jonathan Edwards, a western philosopher, with those of Feyz Kashani, an eastern philosopher. The reason for this study is the numerous conjunctions that are seen in their ideas. These include the harmony of heart and reason in respect to belief, the priority of the heart in the reflection of truth, the belief in centrality of the religion of heart, the necessity of divine grace in the flow of religious knowledge, the emphasis on the esoteric side of religion as opposed to the exoteric side, and the importance of a practical approach to religion. Significant differences also exist between their ideas. For instance, Edwards believes that human nature is sinful and corrupted while Feyz does not believe this is true. Furthermore, Feyz interprets the path of heart to be based on reason, while Edwards has a different point of view.

Industrial fluoride pollution: chronic fluoride poisoning in Cornwall Island cattle

Energy Technology Data Exchange (ETDEWEB)

Krook, L.; Maylin, G.A.

1979-04-01

An aluminum plant on the south bank of the St. Lawrence River, southwest of Cornwall Island, Ontario, Canada, has emitted 0.816 metric tons of fluoride daily since 1973. Considerably higher amounts were emitted from 1959 to 1973. The plant was designated as the major source of fluoride emissions impacting on Cornwall Island. Cattle located on this island showed signs of chronic fluoride poisoning. This poisoning was manifested clinically by stunted growth and dental fluorosis to a degree of severe interference with drinking and mastication. This Cornwall Island herds study indicates that the established tolerance level of fluoride for performance of dairy and beef cattle is not valid since the tolerance level was set based on experiments with healthy calves which were exposed to dietary fluoride from 3 to 4 months of age and not on cattle which were chronically exposed to fluoride from conception to death. 56 references.

During 2014–16, the U.S. Geological Survey, in cooperation with the Edwards Aquifer Authority, documented the geologic framework and hydrostratigraphy of the Edwards and Trinity aquifers within northern Bexar and Comal Counties, Texas. The Edwards and Trinity aquifers are major sources of water for agriculture, industry, and urban and rural communities in south-central Texas. Both the Edwards and Trinity are classified as major aquifers by the State of Texas.The purpose of this report is to present the geologic framework and hydrostratigraphy of the Edwards and Trinity aquifers within northern Bexar and Comal Counties, Tex. The report includes a detailed 1:24,000-scale hydrostratigraphic map, names, and descriptions of the geology and hydrostratigraphic units (HSUs) in the study area.The scope of the report is focused on geologic framework and hydrostratigraphy of the outcrops and hydrostratigraphy of the Edwards and Trinity aquifers within northern Bexar and Comal Counties, Tex. In addition, parts of the adjacent upper confining unit to the Edwards aquifer are included.The study area, approximately 866 square miles, is within the outcrops of the Edwards and Trinity aquifers and overlying confining units (Washita, Eagle Ford, Austin, and Taylor Groups) in northern Bexar and Comal Counties, Tex. The rocks within the study area are sedimentary and range in age from Early to Late Cretaceous. The Miocene-age Balcones fault zone is the primary structural feature within the study area. The fault zone is an extensional system of faults that generally trends southwest to northeast in south-central Texas. The faults have normal throw, are en echelon, and are mostly downthrown to the southeast.The Early Cretaceous Edwards Group rocks were deposited in an open marine to supratidal flats environment during two marine transgressions. The Edwards Group is composed of the Kainer and Person Formations. Following tectonic uplift, subaerial exposure, and erosion near the end of

Status of harbour seals (Phoca vitulina in Atlantic Canada

Directory of Open Access Journals (Sweden)

Mike O Hammill

2010-09-01

Full Text Available Harbour seals are associated with small islets, reefs and rocks exposed at low tide and estuarine habitats throughout eastern Canada. Evidence of harvesting by indigenous people has been found in pre-European contact archaeological excavations. A bounty harvest as well as subsistence and commercial hunting probably lead to a decline in the population from 1949 to the early 1970s. The bounty was removed in 1976, and harbour seals, in the southern parts of their range have been protected since then. There is little information available on total abundance and current population trend. Mitochondrial and microsatellite DNA research has shown separation between Northeast and Northwest Atlantic harbour seals. Within Canada, the subspecies Phoca vitulina concolor shows some population sub-structure with three distinct units that could be separated into Hudson Bay, Gulf of St. Lawrence and Sable Island. Urban development resulting in habitat degradation is probably the most important factor affecting harbour seal populations in AtlanticCanada, although other factors such as incidental catches in commercial fisheries and competition with grey seals may also be important.

Scarce attention has been given to Samuel Taylor Coleridge's engagement with the philosophical theology of Jonathan Edwards, and yet a clear understanding of each thinker's position on determinism and Original Sin is of vital importance if we are understand the lasting significance of their disagreements. There have been a number of studies to take up Coleridge's influence on the American Romantics, but there is no scholarship that has taken into account how the reception of this influence was inflected both by the legacy of Edwards and by the critical response that his theology elicited from Coleridge.

Granular statistical mechanics - Building on the legacy of Sir Sam Edwards

Science.gov (United States)

Blumenfeld, Raphael

When Sir Sam Edwards laid down the foundations for the statistical mechanics of jammed granular materials he opened a new field in soft condensed matter and many followed. In this presentation we review briefly the Edwards formalism and some of its less discussed consequences. We point out that the formalism is useful for other classes of systems - cellular and porous materials. A certain shortcoming of the original formalism is then discussed and a modification to overcome it is proposed. Finally, a derivation of an equation of state with the new formalism is presented; the equation of state is analogous to the PVT relation for thermal gases, relating the volume, the boundary stress and measures of the structural and stress fluctuations.

Supply constraints : Australia and Canada coal industry face logistics and capacity challenges

International Nuclear Information System (INIS)

Borsato, J.

2010-01-01

Australia and Canada are benefiting from a global increase in coal consumption, but face challenges regarding coal and coal export capacity. Coal is Australia's biggest export commodity, accounting for over 50 percent of world coking coal exports, with almost 75 percent of those exports destined for Asian markets, primarily Japan. However, the number of ships delayed at Australian ports hit a record of 223 bulk carriers in early 2010. Compared to Canada, Australia faces greater logistical issues getting coal into port and onto ships at its 9 loading terminals. Two of Canada's 3 major shipping terminals, Westshore and Neptune, have some additional capacity. Its third terminal, Ridley Island, has considerable potential to carry more coal. With 98 percent of all coal moved by rail in Australia, rail issues also hinder growth. A national approach to planning freight transport on both roads and rail is being developed. While infrastructure issues remain the single greatest barrier to export growth for Australia's coal sector, Canada's most immediate issues pertain to mine permitting and mine-site expansion. In 2009, Canada exported 28 million tonnes of coal, 90 percent of it metallurgical. With approximately 70 million tonnes of annual production, mostly in British Columbia and Alberta, coal remains the number one commodity in Canada carried by rails and shipped from ports. 1 fig.

The Edwards Duromedics valve (Baxter Healthcare Corp., Edwards Division, Santa Ana, Calif.) was designed with a self-irrigating hinge mechanism to reduce thromboembolic complications. After good initial clinical results, distribution was suspended in 1988 after reports of valve fracture after 20,000 valves had been implanted. The manufacturer conducted extensive studies to improve the Edwards Duromedics and reintroduced a modified version, which is available as Edwards Tekna. The purpose of the study was the evaluation of long-term results of the original Edwards Duromedics that might be important for the current version, the Edwards Tekna valve. A prospective clinical 10-year follow-up was performed of 508 patients who underwent valve replacement with the Edwards Duromedics valve in the aortic (n = 268), mitral (n = 183), and aortic and mitral (n = 56) position. The perioperative mortality rate was 6.9%; follow-up was 98% complete, comprising 3648 patient-years for a mean follow-up of 86 months (range: 33 to 144 months). The actuarial freedom from complications at the 10-year follow-up and the incidence rate (percent per patient-year) were as follows: late mortality rate, 69.2% +/- 2.4% (3.5% per patient-year); thromboembolism, 90.7% +/- 1.6% (0.96% per patient-year); anticoagulation-related hemorrhage, 87.7% +/- 1.7% (1.34% per patient-year); prosthetic valve endocarditis, 96.7% +/- 0.09% (0.38% per patient-year); valve-related mortality rate, 89.3% +/- 1.6% (1.21% per patient-year); valve failure, 86.2% +/- 1.85% (1.54% per patient-year); and valve-related morbidity and mortality rate, 71.1% +/- 2.3% (3.2% per patient-year). Three leaflet escapes were observed (one lethal, two successful reoperations; 99.1% +/- 0.05% freedom, 0.08% per patient-year). All patients functionally improved (86% in New York Heart Association classes I and II), and incidence of anemia was insignificant. These results confirm that the Edwards Duromedics valve shows excellent performance

Habibov, Nazim N; Fan, Lida

2010-11-01

In the mid-1990s, the responsibilities to design, implement, and evaluate social welfare programs were transferred from federal to local jurisdictions in many countries of North America and Europe through devolution processes. Devolution has caused the need for a technique to measure and compare the performances of social welfare programs across multiple jurisdictions. This paper utilizes Data Envelopment Analysis (DEA) for a comparison of poverty reduction performances of jurisdictional social welfare programs across Canadian provinces. From the theoretical perspective, findings of this paper demonstrates that DEA is a promising method to evaluate, compare, and benchmark poverty reduction performance across multiple jurisdictions using multiple inputs and outputs. This paper demonstrates that DEA generates easy to comprehend composite rankings of provincial performances, identifies appropriate benchmarks for each inefficient province, and estimates sources and amounts of improvement needed to make the provinces efficient. From a practical perspective the empirical results presented in this paper indicate that Newfoundland, Prince Edwards Island, and Alberta achieve better efficiency in poverty reduction than other provinces. Policy makers and social administrators of the ineffective provinces across Canada may find benefit in selecting one of the effective provinces as a benchmark for improving their own performance based on similar size and structure of population, size of the budget for social programs, and traditions with administering particular types of social programs.

Invited commentary on 'Robert G Edwards and the Roman Catholic Church'.

Head, Ivan Francis

2011-06-01

In this issue of Reproductive BioMedicine Online, Benagiano, Carrara and Filippi have produced a clearly written and comprehensive account of why the Roman Catholic Church has not welcomed the award of the 2010 Nobel Prize in Physiology and Medicine to Dr Robert G Edwards for the development of human IVF. I commend the article for its clarity and lucidity but attempt to point out some areas where disagreement even with its nuanced opposition to IVF may be legitimate. I try to make some simple comments that explain why this is so and I suggest some areas to which contemporary theology and philosophy can commit itself. But it is good to see even a nuanced response to the work of Robert G Edwards rather than a blanket condemnation. Copyright © 2011 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

Review of experimental and natural invertebrate hosts of sealworm (Pseudoterranova decipiens and its distribution and abundance in macroinvertebrates in eastern Canada

Directory of Open Access Journals (Sweden)

David J Marcogliese

2001-11-01

Full Text Available Experimental and natural invertebrate intermediate hosts of sealworm (Pseudoterranova decipiens as well as transmission experiments of sealworm from invertebrates to fish are reviewed and summarized. Experimental hosts include copepods, mysids, cumaceans, isopods, amphipods, decapods, annelids, and molluscs. Invertebrates collected from eastern Canada between 1989 and 1995 were checked for nematode infections by microscopic examination of dissected animals or enzymatic digestion of bulk samples. Third-stage larval sealworm were found in mysids (Neomysis americana, Mysis stenolepis from Passamaquoddy Bay, the Bras d’Or Lakes, inshore Cape Breton, Sable Island and Sable Island Bank. Infected amphipods (Amphiporeia virginiana, Americorchestia megalophthalma, Gammarus spp. were found only on Sable Island. Typical infection rates in macroinvertebrates were 1-4/1000. No sealworm infections were found in approximately 18,000 amphipods examined from Sable Island Bank, the site of the most heavily infected fishes in eastern Canada. In Wallace Lake, a brackish pond on Sable Island, infection rates were much higher in mysids than in amphipods. Estimates of rates of transmission of sealworm from invertebrates to fish were derived from infection levels in Wallace Lake and feeding experiments involving sticklebacks and invertebrate prey. It is concluded that mysids may be much more important than amphipods in transmitting sealworm to fish hosts.

Predator Exclosures Enhance Reproductive Success but Increase Adult Mortality of Piping Plovers (Charadrius melodus

Directory of Open Access Journals (Sweden)

Colleen Barber

2010-12-01

Full Text Available Piping Plovers (Charadrius melodus are listed as endangered throughout Canada and the United States Great Lakes region. Most attempts to increase their numbers have focused on enhancing reproductive success. Using 22 years of data collected by Parks Canada in Prince Edward Island National Park of Canada, we examined whether predator exclosures installed around Piping Plover nests increased nest success and hatching and fledging success when compared to nests without exclosures. Nests with exclosures were significantly more likely to hatch at least one egg than nests without exclosures, and they hatched a significantly greater number of young. The greater reproductive success observed in exclosed nests is likely due to the increased protection from predators that the exclosures conferred; significantly fewer exclosed nests were depredated than nonexclosed nests. However, significantly more exclosed than nonexclosed nests were abandoned by adults, and they had significantly greater adult mortality. Whether benefits of increased reproductive success from exclosures outweigh costs of increased abandonment and adult mortality remains unknown, but must be considered.

Translational mini-review series on vaccines: The Edward Jenner Museum and the history of vaccination.

Morgan, A J; Parker, S

2007-03-01

Edward Jenner's discovery of vaccination must rank as one of the most important medical advances of all time and is a prominent example of the power of rational enquiry being brought to bear during the Age of Enlightenment in 18th century Europe. In the modern era many millions of lives are saved each year by vaccines that work essentially on the same principles that were established by Edward Jenner more than 200 years ago. His country home in Berkeley, Gloucestershire, is where he carried out his work and where he spent most of his life. The building is now a museum in which the life and times of Jenner are commemorated including not only the discovery of smallpox vaccination but also his other important scientific contributions to natural history and medicine. The trustees of the Edward Jenner museum are committed to promoting the museum as a real and "virtual" educational centre that is both entertaining and informative.

Bed-material entrainment and associated transportation infrastructure problems in streams of the Edwards Plateau, central Texas

Science.gov (United States)

Heitmuller, Franklin T.; Asquith, William H.

2008-01-01

The Texas Department of Transportation commonly builds and maintains low-water crossings (LWCs) over streams in the Edwards Plateau in Central Texas. LWCs are low-height structures, typically constructed of concrete and asphalt, that provide acceptable passage over seasonal rivers or streams with relatively low normal-depth flow. They are designed to accommodate flow by roadway overtopping during high-flow events. The streams of the Edwards Plateau are characterized by cobble- and gravel-sized bed material and highly variable flow regimes. Low base flows that occur most of the time occasionally are interrupted by severe floods. The floods entrain and transport substantial loads of bed material in the stream channels. As a result, LWCs over streams in the Edwards Plateau are bombarded and abraded by bed material during floods and periodically must be maintained or even replaced.

Holocene Tree Line and Climate Change on the Queen Charlotte Islands, Canada

Science.gov (United States)

Pellatt, Marlow G.; Mathewes, Rolf W.

1997-07-01

Palynological study of two subalpine ponds on the Queen Charlotte Islands reveals changes in tree line and climate during the Holocene. The findings agree with previous reconstructions, from nearby Louise Pond on the Queen Charlotte Islands, that suggest a warmer-than-present climate and higher-than-present tree lines in the early Holocene (ca. 9600-6600 14C yr B.P.). Basal ages at SC1 Pond and Shangri-La Bog indicate that the basins did not hold permanent water before 7200 14C yr B.P., consistent with a warmer and drier early Holocene previously inferred from Louise Pond. Pollen and plant macrofossils indicate the initial establishment of subalpine conditions by 6090 ± 90 14C yr B.P., similar to the 5790 ± 130 14C yr B.P. age for cooling inferred from Louise Pond. Conditions similar to present were established at SC1 Pond by 3460 ± 100 14C yr B.P., confirming the previous estimate of 3400 14C yr B.P. at Louise Pond. This 3400 14C yr B.P. vegetation shift on the Queen Charlotte Islands corresponds with the beginning of the Tiedemann glacial advance in the south-coastal mountains of British Columbia (ca. 3300 14C yr B.P.), the Peyto and Robson glacial advances between 3300 and 2800 14C yr B.P. in the Rocky Mountains, and climatic cooling inferred from palynological studies throughout southern British Columbia, northern Washington, and southeast Alaska. These findings confirm that changes in regional climate influenced changes in vegetation in coastal British Columbia.

Few studies have examined potential disparities in access to transportation infrastructures, an important determinant of population health. To examine individual- and area-level disparities in access to the road network, public transportation system, and a public bicycle share program in Montreal, Canada. Examining associations between sociodemographic variables and access to the road network, public transportation system, and a public bicycle share program, 6,495 adult respondents (mean age, 48.7 years; 59.0 % female) nested in 33 areas were included in a multilevel analysis. Individuals with lower incomes lived significantly closer to public transportation and the bicycle share program. At the area level, the interaction between low-education and low-income neighborhoods showed that these areas were significantly closer to public transportation and the bicycle share program controlling for individual and urbanicity variables. More deprived areas of the Island of Montreal have better access to transportation infrastructure than less-deprived areas.

Map Showing Geology and Hydrostratigraphy of the Edwards Aquifer Catchment Area, Northern Bexar County, South-Central Texas

Clark, Amy R.; Blome, Charles D.; Faith, Jason R.

2009-01-01

Rock units forming the Edwards and Trinity aquifers in northern Bexar County, Texas, are exposed within all or parts of seven 7.5-minute quadrangles: Bulverde, Camp Bullis, Castle Hills, Helotes, Jack Mountain, San Geronimo, and Van Raub. The Edwards aquifer is the most prolific ground-water source in Bexar County, whereas the Trinity aquifer supplies water for residential, commercial, and industrial uses for areas north of the San Antonio. The geologic map of northern Bexar County shows the distribution of informal hydrostratigraphic members of the Edwards Group and the underlying upper member of the Glen Rose Limestone. Exposures of the Glen Rose Limestone, which forms the Trinity aquifer alone, cover approximately 467 km2 in the county. This study also describes and names five informal hydrostratigraphic members that constitute the upper member of the Glen Rose Limestone; these include, in descending order, the Caverness, Camp Bullis, Upper evaporite, Fossiliferous, and Lower evaporite members. This study improves our understanding of the hydrogeologic connection between the two aquifers as it describes the geology that controls the infiltration of surface water and subsurface flow of ground water from the catchment area (outcropping Trinity aquifer rocks) to the Edwards water-bearing exposures.

3D Finite Element Modeling for Possible Creeping Behavior of Gas Hydrate-related Slipstream Submarine Slide, offshore Vancouver Island, Canada

LONG, S.; He, T.; Lan, K.; Spence, G.; Yelisetti, S.

2017-12-01

Natural gas hydrate-related submarine landslides have been identified on worldwide continental slope. Being a potential risk for marine environment and engineering projects, it has been a hot topic of hydrate research in recent decades. The study target is Slipstream submarine landslide, one of the slope failures on the frontal ridges of the Northern Cascadia accretionary margin, off Vancouver Island, Canada. The previous studies of P- & S-wave velocity structure based on OBS (Ocean Bottom Seismometer) data of SeaJade (Seafloor Earthquake Array - Japan Canada Cascadia Experiment) project indicated that there are two high concentration gas-hydrate layers within the ridge, one is at a depth of 100 mbsf (meter beneath the seafloor) with anomalous high P-wave velocities and the other is just above the prominent BSR (bottom-simulating reflector) at a depth of 265-275 mbsf. In this study we investigated the possible creeping behavior of gas hydrate layer to examine the critical instability of the ridge slope using the finite element method for self weight and additional stress (e.g., mega earthquake) conditions. The elastic and elasticoplasticity moduli of gas hydrate layer were obtained from laboratory measurements for different uniaxial pressure tests, which indicated that the sediments behave elastically for uniaxial pressures below 6 MPa, but elasticoplastically between 6-6.77 MPa. The modeled shear stress distribution indicated that the current sliding surface is more likely connected with the shallow high-velocity gas hydrate layer and sliding process related with gas hydrate starts from the toe of the slope and then progressively retreats to the place of current headwall, in a series of triangular blocks or wedges. Since the study area is in the earthquake belt, the large seismic acceleration will greatly affect the stress field and pore pressure distribution within the ridge, and the landslide is going to happen and supposedly at the shallow high-velocity gas

An increasing prevalence since 2010 of Serratia marcescens harbouring the Ambler class A carbapenemase SME prompted us to further characterize these isolates. Isolates harbouring bla(SME) were identified by PCR and sequencing. Phenotypic analysis for carbapenemase activity was carried out by a modified Hodge test and a modified Carba NP test. Antimicrobial susceptibilities were determined by Etest and Vitek 2. Typing was by PFGE of macrorestriction digests. Whole-genome sequencing of three isolates was carried out to characterize the genomic region harbouring the bla(SME)-type genes. All S. marcescens harbouring SME-type enzymes could be detected using a modified Carba NP test. Isolates harbouring bla(SME) were resistant to penicillins and carbapenems, but remained susceptible to third-generation cephalosporins, as well as fluoroquinolones and trimethoprim/sulfamethoxazole. Isolates exhibited diverse genetic backgrounds, though 57% of isolates were found in three clusters. Analysis of whole-genome sequence data from three isolates revealed that the bla(SME) gene occurred in a novel cryptic prophage genomic island, SmarGI1-1. There has been an increasing occurrence of S. marcescens harbouring bla(SME) in Canada since 2010. The bla(SME) gene was found on a genomic island, SmarGI1-1, that can be excised and circularized, which probably contributes to its dissemination amongst S. marcescens. © The Author 2014.

Pierce, S. A.; Collins, J.; Banner, J.

2017-12-01

Understanding the temporal patterns in datasets related to climate, recharge, and water resource conditions is important for informing water management and policy decisions. Data analysis and pipelines for evaluating these disparate sources of information are challenging to set up and rely on emerging informatics tools to complete. This project gathers data from both historical and recent sources for the Edwards Aquifer of central Texas. The Edwards faces a unique array of challenges, as it is composed of karst limestone, is susceptible to contaminants and climate change, and is expected to supply water for a rapidly growing population. Given these challenges, new approaches to integrating data will be particularly important. Case study data from the Edwards is used to evaluate aquifer and hydrologic system conditions over time as well as to discover patterns and possible relationships across the information sources. Prior research that evaluated trends in discharge and recharge of the aquifer is revisited by considering new data from 1992-2015, and the sustainability of the Edwards as a water resource within the more recent time period is addressed. Reusable and shareable analytical data pipelines are constructed using Jupyter Notebooks and Python libraries, and an interactive visualization is implemented with the information. In addition to the data sources that are utilized for the water balance analyses, the Global Surface Water Monitoring System from the University of Minnesota, a tool that integrates a wide number of satellite datasets with known surface water dynamics and machine learning, is used to evaluate water body persistence and change over time at regional scales. Preliminary results indicate that surface water body over the Edwards with differing aerial extents are declining, excepting some dam-controlled lakes in the region. Other existing tools and machine learning applications are also considered. Results are useful to the Texas Water Research

Pre-industrial and recent (1970-2010) atmospheric deposition of sulfate and mercury in snow on southern Baffin Island, Arctic Canada.

Sulfate (SO4(2-)) and mercury (Hg) are airborne pollutants transported to the Arctic where they can affect properties of the atmosphere and the health of marine or terrestrial ecosystems. Detecting trends in Arctic Hg pollution is challenging because of the short period of direct observations, particularly of actual deposition. Here, we present an updated proxy record of atmospheric SO4(2-) and a new 40-year record of total Hg (THg) and monomethyl Hg (MeHg) deposition developed from a firn core (P2010) drilled from Penny Ice Cap, Baffin Island, Canada. The updated P2010 record shows stable mean SO4(2-) levels over the past 40 years, which is inconsistent with observations of declining atmospheric SO4(2-) or snow acidity in the Arctic during the same period. A sharp THg enhancement in the P2010 core ca 1991 is tentatively attributed to the fallout from the eruption of the Icelandic volcano Hekla. Although MeHg accumulation on Penny Ice Cap had remained constant since 1970, THg accumulation increased after the 1980s. This increase is not easily explained by changes in snow accumulation, marine aerosol inputs or air mass trajectories; however, a causal link may exist with the declining sea-ice cover conditions in the Baffin Bay sector. The ratio of THg accumulation between pre-industrial times (reconstructed from archived ice cores) and the modern industrial era is estimated at between 4- and 16-fold, which is consistent with estimates from Arctic lake sediment cores. The new P2010 THg record is the first of its kind developed from the Baffin Island region of the eastern Canadian Arctic and one of very few such records presently available in the Arctic. As such, it may help to bridge the knowledge gap linking direct observation of gaseous Hg in the Arctic atmosphere and actual net deposition and accumulation in various terrestrial media.

Edward A. Bouchet was the first African American to receive the doctorate in any field of knowledge in the United States and that area was physics. He was granted the degree in 1876 from Yale University making him at that time one of the few persons to hold the physics doctorate from an American university. His prior education included the Hopkins Grammar School and Yale College (BA in 1874). After Yale, Bouchet taught mathematics, physics, and chemistry for over twenty-five years at the Institute for Colored Youth in Philadelphia. During the following two decades, he was employed in positions ranging from high school principal to employment by the federal government. Bouchet played a significant role in the education of African Americans through his teaching and mentoring activities. He was one among a small group of African Americans who achieved advanced training and education within decades of the American civil war. These individuals provided direction, leadership, and role models for what eventually became the civil/human rights movements. The year 2001 marks the 125th celebration of his receiving the doctorate. We present details of his life and career with an emphasis on the influence of the political and social forces exerted on him by society.

Bedrock geology and hydrostratigraphy of the Edwards and Trinity aquifers within the Driftwood and Wimberley 7.5-minute quadrangles, Hays and Comal Counties, Texas

Science.gov (United States)

Clark, Allan K.; Morris, Robert R.

2017-11-16

The Edwards and Trinity aquifers are major sources of water in south-central Texas and are both classified as major aquifers by the State of Texas. The population in Hays and Comal Counties is rapidly growing, increasing demands on the area’s water resources. To help effectively manage the water resources in the area, refined maps and descriptions of the geologic structures and hydrostratigraphic units of the aquifers are needed. This report presents the detailed 1:24,000-scale bedrock hydrostratigraphic map as well as names and descriptions of the geologic and hydrostratigraphic units of the Driftwood and Wimberley 7.5-minute quadrangles in Hays and Comal Counties, Tex.Hydrostratigraphically, the rocks exposed in the study area represent a section of the upper confining unit to the Edwards aquifer, the Edwards aquifer, the upper zone of the Trinity aquifer, and the middle zone of the Trinity aquifer. In the study area, the Edwards aquifer is composed of the Georgetown Formation and the rocks forming the Edwards Group. The Trinity aquifer is composed of the rocks forming the Trinity Group. The Edwards and Trinity aquifers are karstic with high secondary porosity along bedding and fractures. The Del Rio Clay is a confining unit above the Edwards aquifer and does not supply appreciable amounts of water to wells in the study area.The hydrologic connection between the Edwards and Trinity aquifers and the various hydrostratigraphic units is complex because the aquifer system is a combination of the original Cretaceous depositional environment, bioturbation, primary and secondary porosity, diagenesis, and fracturing of the area from Miocene faulting. All of these factors have resulted in development of modified porosity, permeability, and transmissivity within and between the aquifers. Faulting produced highly fractured areas which allowed for rapid infiltration of water and subsequently formed solutionally enhanced fractures, bedding planes, channels, and caves that

George’s Island, Labrador - A high-density predator-free refuge for a woodland caribou subpopulation?

2007-04-01

Full Text Available The movement patterns and demographic parameters were measured for caribou (Rangifer tarandus caribou on George’s Island (Labrador, Canada to determine if the population is separate from the Mealy Mountain Caribou Herd. Movements between George’s Island caribou and nearby Mealy Mountain caribou were examined through satellite telemetry (April 2005 to April 2006. Demographic information was collected through aerial classification surveys. The predator-free island is currently maintaining a density of 22.5-26.5 caribou/km2. Female survival appears high and the recruitment rate in late fall-early spring was 19.0-29.2% calves. Mainland caribou moved very little throughout the year, travelling no more than 53.7 km on average from their initial collaring locations. Also, satellite data indicated no mixing between animals on George’s Island and the mainland. The elevated caribou density and high proportion of calves suggest that George’s Island could at times be acting as a predator-free recruitment area and that George’s Island may be a subpopulation from which animals disperse to the mainland.

After failed aggressive medical therapy and surgical turn down, an Edwards SAPIEN XT valve was deployed in the tricuspid bioprosthesis via the right femoral vein. Adaptations to the standard transfemoral transcatheter aortic valve implantation (TAVI) technique included: (1) crossing the tricuspid bioprosthesis with a balloon floatation catheter; (2) temporary pacing wire in the coronary sinus rather than the right ventricle; (3) mounting of the SAPIEN XT valve in the reverse orientation to transfemoral TAVI; and (4) fine positioning of the final valve position pre-deployment by 3D transoesophageal echocardiography (3D TOE) alone due to complete radiolucency of the tricuspid bioprosthesis. The procedure was completed without complication and resulted in significant symptomatic improvement. Deployment of an Edwards SAPIEN valve in a tricuspid bioprosthesis via the femoral vein is feasible and, with careful adaptations to established TAVI techniques, can be performed without complications and with good clinical response.

Latitudinal distribution of cesium-137 fallout in 1990 on Saxifraga oppositofolia from Ellesmere Island, Canada

International Nuclear Information System (INIS)

France, R.L.; Svoboda, J.; Taylor, H.W.

1993-01-01

During the first ski traverse of Ellesmere Island in spring 1990, purple saxifrage (Saxifraga oppositifolia) was collected at 10 sites from 76 to 82 degrees N. Measured 137 Cs levels in this cushion plant displayed a progressive decrease in activity north of 78 degrees, reflecting past global patterns of radionuclide fallout. Lower 137 Cs activity at the southern end of Ellesmere Island may reflect a northward shift of the distribution maximum since a previous latitudinal survey conducted in 1979-1980. Levels of 137 in three species of lichen were consistently higher than those for nearby saxifrage, possibly owing to the larger exposure to fallout for much of the year and the slower rate of lichen growth. In support of previous research, no 134 Cs was detected, which indicated that Chernobyl fallout had not been deposited in significant quantities at these extreme northern latitudes. Specific activities in 1990 of saxifrage samples were compared with similar samples collected during 1979-1980 to derive an effective half-life of 6.2 ± 1.0 years for northern Ellesmere Island

1996-10-01

Numerical simulations, with the Subsurface Transport Over Multiple Phases (STOMP) simulator, were applied to the field demonstration of an in-well vapor-stripping system at Edwards Air Force Base (AFB), near Mojave, California. The demonstration field site on the Edwards AFB was previously contaminated from traversing groundwater that was contained a varied composition of volatile organic compounds (VOCs), which primarily includes trichloroethylene (TCE). Contaminant TCE originated from surface basin that had been used to collect runoff during the cleaning of experimental rocket powered planes in the 1960s and 1970s. This report documents those simulations and associated numerical analyses. A companion report documents the in- well vapor-stripping demonstration from a field perspective

Tourist brochures describe Prince Edward Island (PEI) as an island with pastoral landscapes and sandy beaches. At the same time, PEI is encouraging and actively supporting the development of a major wind energy industry. PEI is also promoting itself as Canada's green province. This report discussed a wind energy survey that was implemented to capture perceptions of wind energy production and wind farms, and their perceived effects on the landscape. Specifically, the survey questioned whether wind farms fit with the gentle island brand for visitors, and whether they support the attempt to label PEI as a green province. The survey also compared perceptions of renewable and non-renewable energy generation methods and determined if there was support for further expansion of wind farms on PEI. The report discussed the objectives of the study as well as the methodology including data collection; statistical issues; and sample characteristics. General travel data for visitors was also presented, such as composition and size of travel party; type of visitation; and regions visited while on PEI. Topics and results that were addressed in the survey included propensity for taking scenic driving tours; percentage of electricity generated from coal, gas, oil, or diesel; desired method to generate electricity; willingness to pay for electricity from renewable energy sources; impressions of fossil based methods; impressions of wind power; percentage of electricity generated from wind turbines; perception of the phrase promoting PEI as Canada's green province; seeing a wind farm on PEI; and attitudes toward wind farms on PEI. In general, the report demonstrated support from both Islanders and visitors for the development of energy though renewable sources, particularly wind energy. tabs., figs.

The crustal structure of Ellesmere Island, Arctic Canada—teleseismic mapping across a remote intraplate orogenic belt

Science.gov (United States)

Schiffer, Christian; Stephenson, Randell; Oakey, Gordon N.; Jacobsen, Bo H.

2016-03-01

Ellesmere Island in Arctic Canada displays a complex geological evolution. The region was affected by two distinct orogenies, the Palaeozoic Ellesmerian orogeny (the Caledonian equivalent in Arctic Canada and Northern Greenland) and the Palaeogene Eurekan orogeny, related to the opening of Baffin Bay and the consequent convergence of the Greenland plate. The details of this complex evolution and the present-day deep structure are poorly constrained in this remote area and deep geophysical data are sparse. Receiver function analysis of seven temporary broad-band seismometers of the Ellesmere Island Lithosphere Experiment complemented by two permanent stations provides important data on the crustal velocity structure of Ellesmere Island. The crustal expression of the northernmost tectonic block of Ellesmere Island (˜82°-83°N), Pearya, which was accreted during the Ellesmerian orogeny, is similar to that at the southernmost part, which is part of the Precambrian Laurentian (North America-Greenland) craton. Both segments have thick crystalline crust (˜35-36 km) and comparable velocity-depth profiles. In contrast, crustal thickness in central Ellesmere Island decreases from ˜24-30 km in the Eurekan fold and thrust belt (˜79.7°-80.6°N) to ˜16-20 km in the Hazen Stable Block (HSB; ˜80.6°-81.4°N) and is covered by a thick succession of metasediments. A deep crustal root (˜48 km) at ˜79.6°N is interpreted as cratonic crust flexed beneath the Eurekan fold and thrust belt. The Carboniferous to Palaeogene sedimentary succession of the Sverdrup Basin is inferred to be up to 1-4 km thick, comparable to geologically-based estimates, near the western margin of the HSB.

Peary caribou distribution within the Bathurst Island Complex relative to the boundary proposed for Qausuittuq National Park, Nunavut

Full Text Available How caribou (Rangifer tarandus, including Peary caribou (R. t. pearyi, use their annual ranges varies with changes in abundance. While fidelity to some seasonal ranges is persistent, use of other areas changes. Consequently, understanding changes in seasonal distribution is useful for designing boundaries of protected areas for caribou conservation. A case in point is the proposed Qausuittuq (Northern Bathurst Island National Park for Bathurst Island and its satellite islands in the High Arctic of Canada. Since 1961, Peary caribou have been through three periods of high and low abundance. We examined caribou distribution and composition mapped during nine systematic aerial surveys (1961–2013, unsystematic helicopter surveys (1989–98, and limited radio-collaring from 1994–97 and 2003–06. While migration patterns changed and use of southern Bathurst Island decreased during lows in abundance, use of satellite islands, especially Cameron Island for winter range, persisted during both highs and lows in abundance. The northeast coast of Bathurst Island was used to a greater extent during the rut and during summer at low abundance. We suggest that Park boundaries which include Cameron Island and the northeast coast of Bathurst Island will be more effective in contributing to the persistence of Peary caribou on the Bathurst Island Complex.

Para além de uma atualização do conceito de imperialismo, central em sua obra, quatro outros temas tratados por ele nos interessam aqui diretamente: o primeiro é o presente poder hegemônico exercido pelo governo dos Estados Unidos desde o fim da Segunda Guerra Mundial e que nos interpela sobre os desafios de uma interdependência transnacional, sobre a construção de uma ordem mundial efetivamente democrática. O segundo tema é a questão nacional, quando o autor aponta os riscos de uma consciência nacional despreparada ou ainda desvirtuada após as lutas de independência e libertação.

The development of CANDU (Canada Deuterium Uranium) type reactors in Canada is traced. What is CANDU? and how does it differ from a pressurized water reactor? Whey did Canada adopt this design? What factors have led to its success? These questions are asked and answered. First the design itself is explained. Technical problems are considered and figures on operating reliability presented. The economic advantages of CANDU are shown by comparing electricity generating costs at CANDU stations with those at coal-fired stations. Future CANDU options are discussed and prospects for CANDU considered. (U.K.)

A case study of contaminants on military ranges: Camp Edwards, Massachusetts, USA

Clausen, Jay; Robb, Joe; Curry, Diane; Korte, Nic

2004-01-01

An extensive investigation at the Camp Edwards, Massachusetts Military Reservation (MMR) demonstrates that assessment of groundwater and soil contamination at military ranges can be limited primarily to explosive-related compounds such as RDX, HMX, perchlorate, TNT and their transformation products. A modified analytical method is recommended to expand the list of explosives and to improve the detection limits. Analyses of metals, VOCs, SVOCs, and TICs are unnecessary. Soil samples may require the analyses of PAHs and PCNs for burn areas. Camp Edwards, as one of the few military ranges that have been exhaustively investigated for contaminants, is an ideal point of departure for evaluating other ranges. The permeable site soils promote leaching of contaminants and inhibit biotic and abiotic transformations. Moreover, the site has experienced an unusual extent of activities in its more than ninety years of active use. The recommendations in this report are based on data obtained for more than 200 analytes from more than 15,000 environmental samples. - Assessment of groundwater and soil contamination at US military ranges can be limited primarily to explosive-related compounds

Sound cable crossing brings inexpensive electric power to Long Island

Grzan, J.; Goyette, R.

1992-01-01

This paper reports that while many electric-utility customers in New York State benefit from inexpensive hydroelectric power from Canada and upstate New York, lack of sufficient transmission connections have prevented this electricity from reaching Long Island. However, a newly constructed underground/underwater link capable of carrying 700-MW now transmits low-cost electricity to the island, saving money for customers. The self-contained fluid-filled cable used for the underwater portion of the project is the largest underwater cable in the world. The use of high-pressure, fluid-filled pipe-type cable on the land portion represents the largest application of paper-polypropylene-paper (PPP) insulated cable in the United States. State-of-the-art technologies were implemented in the use of temperature monitoring and leak detection systems, SF 6 gas-insulated substation, and underwater cable laying and embedment techniques

Representation and Imperialism in Edward Said

Directory of Open Access Journals (Sweden)

Bruno Sciberras de Carvalho

2010-12-01

Full Text Available Based on the idea that culture and identities involve a politically built process, the importance of the concepts of representation and imperialism in the work of Edward Said is discussed. The article analyses two of the author’s general proposals. Firstly, the thesis of the centrality of cultural dimension in political relations, which leads to the review of postulates that consider culture as a mere reflection of a phenomena seen as essential or as a sphere isolated from the power practices. Secondly, the study examines how the author’s conception of imperialism is used as a means of identification that keep structures of authority and hegemony, which, in turn, may be defied by processes of resistance. Finally, the validity of the open character of Said’s political theory is debated, which encompasses both the power of representations and an action of political questioning.

Oil and gas developments in western Canada in 1981

Energy Technology Data Exchange (ETDEWEB)

Hay, P.W.; Robertson, D.C.

1982-12-01

In 1981 there was a marked slump in drilling activity in western Canada, resulting from the combined effects of the National Energy Program (NEP), economic recession and a worldwide oil surplus. The number of wells drilled dropped by 22% to a total of 6,904. Exploratory drilling decreased 19% to 3,074 wells, and development drilling decreased 25% to 3,830 wells. The exploratory success rate also decreased to 62% in 1981, based on 740 oil discoveries and 1,172 gas discoveries. The development success rate decreased slightly to 88%, with 1,334 oil discoveries and 2,034 gas discoveries. Average well depth increased in four of the five western areas, but total revenue from land sales plummetted to half of the previous years' record totals. Average price per hectare also dropped. In Alberta, significant exploration activity was centred in the Shekilie, Golden-Evi and West Pembina areas, while major gas discoveries were made at Whiskey and Elmworth, and oil discoveries at Tangent. No significant new discoveries were made in British Columbia or Saskatchewan, but the 1980 Manitoba oil discovery at Waskada continued to stimulate activity. Preliminary results from the Nechako Basin drilling in central British Columbia proved to be disappointing with three successive dry holes. In the Arctic Islands, two major oil discoveries were made at Skate and Cisco, off Lougheed Island and a gas discovery at MacLean. Beaufort Sea drilling was hampered by weather, but nonetheless resulted in major oil discoveries a Koakoak and at a Kopanoar follow-up well. The year 1981 will probably be viewed as a major turning point in exploration in western Canada, with interest shifting from the provinces to the frontiers, and the participants now mainly Canadian-controlled companies.

The first French transapical transcatheter aortic valve implantation (TAVI) was performed in July 2007 in our department. To report 4-year outcomes of transapical implantation with the Edwards transcatheter bioprosthesis. We prospectively evaluated consecutive patients who underwent transapical implantation with an Edwards transcatheter bioprosthesis between July 2007 and October 2011. Patients were not suitable for conventional surgery (due to severe comorbidities) or transfemoral implantation (due to poor femoral access). Among 61 patients (59.0% men), mean logistic EuroSCORE was 27.5 ± 14.9% and mean age was 81.0 ± 6.8 years. Successful valve implantation was achieved in 59/61 patients (96.7%) of patients. The other two patients required conversion to conventional surgery due to prosthesis embolization and died. Six additional patients died in the postoperative period. Causes of perioperative death were two septic shocks (one of peritonitis), two multi-organ failure, one ventricular fibrillation and one respiratory insufficiency. Intraprocedural stroke was not observed in any patient. The actuarial survival rates at 1, 2 and 4 years were 73.8%, 67.2% and 41.0%. During this 4-year period, four patients died of cardiovascular events, but no impairment of transprosthesis gradient was observed. Our series of 61 patients who underwent transapical implantation of the Edwards transcatheter bioprosthesis shows satisfactory results, similar to other reports, considering the high level of severity of patients referred for this method. Transapical access is a reliable alternative method for patients that cannot benefit from a transfemoral approach. Copyright © 2012. Published by Elsevier Masson SAS.

Edward Henry Sieveking, eminent London physician of Victorian times, is best known as the speaker at the historic meeting at which the chairman, Sir Charles Locock, seem to overshadow him in announcing the introduction of bromide--the first effective anti-convulsant. But in fact Sieveking had announced a most important conceptual advance in epileptology--the demise of "essential epilepsy". In addition his book, published soon after and based upon his lecture, is an important historical resumé of Victorian era concepts and management of epilepsy. His important contributions to the understanding and management of this condition are discussed herein.

Renewable based hydrogen energy projects in remote and island communities

Miles, S.; Gillie, M.

2009-01-01

Task 18 working group of the International Energy Agency's Hydrogen Implementing Agreement has been evaluating and documenting experiences with renewable based hydrogen energy projects in remote and island communities in the United Kingdom, Canada, Norway, Iceland, Gran Canaria, Spain and New Zealand. The objective was to examine the lessons learned from existing projects and provide recommendations regarding the effective development of hydrogen systems. In order to accomplish this task, some of the drivers behind the niche markets where hydrogen systems have already been developed, or are in the development stages, were studied in order to determine how these could be expanded and modified to reach new markets. Renewable based hydrogen energy projects for remote and island communities are currently a key niche market. This paper compared various aspects of these projects and discussed the benefits, objectives and barriers facing the development of a hydrogen-based economy

Cultural Imperialism of the West in the Work of Edward W. Said

Directory of Open Access Journals (Sweden)

Ranka Jeknić

2006-09-01

Full Text Available This article presents the main ideas and views of Edward W. Said on the relationship between culture and imperialism, and also on the link between Western culture and the formation of imperialism. Hence, special attention is given to Said’s interpretation of novels as constructions of the geopolitical reality: i.e. the characteristics of “imperialism” are examined as found in such English and French writers as Jane Austen, Rudyard Kipling, Joseph Conrad and Albert Camus, illustrating the way how novels as an aesthetic form participated in the “cultural construction” of colonialism. In the next part of the discussion, the paper presents another main topic of Edward Said that reveals how “cultural imperialism”, “orientalism” and “covering Islam” are still, unfortunately, current topics. Special attention is given to Said's demystification of the opposition between “us” and “them”, or “the West” and “Others”, through the example of the relationship between “the West” and “Islam”. Behind this issue, unequal power relations exist, as well as unequal relations of power and knowledge; “anti-systemic movements”, especially, and the “post-colonial discourse”, in general, warns us of this.

Edward Albee’s The Zoo Story: Echo/es of Contemporary Subversive Culture

2016-02-01

Full Text Available The post-world war II American social and cultural setting was ambiguously featured with enforced conformity in the name of prosperity and Americanization of the nation. Despite of this fact, American writers, especially, dramatists conveyed their message against this fixation through variety and intellectuality. Edward Albee’s The Zoo Story is one of those literary assets which dedicatedly cut through the illusions of contemporary American social and cultural ethos. Here, his characters are seen struggling constantly with their insecurities and existential angst in the society. He presents America, the so-called ‘Land of Free and Home of Braves’ (note 1, in such a portrayal that unveils the traps of cages and confinement underneath. The target of this paper is to trace Edward Albee’s heightened awareness about the post-war American socio-cultural reality evident in The Zoo Story. It also looks for the voice in which the text echoes out the anti-communist, materialistic, gender-coded boundaries, coupled with paradoxical media representations, religious bordering and how Albee challenges these issues with an anti-establishment tone. Keywords: subversive culture, anti-communism, media, religion and homosexuality

Case studies of green roof policy from Canada

Energy Technology Data Exchange (ETDEWEB)

Marshall, S. [Canada Mortgage and Housing Corp., Ottawa, ON (Canada)

2006-07-01

In order to overcome environmental, economic, and social challenges, such as stormwater management, heat island effects, reducing energy use in buildings and increasing amenity space, green roof technology has been a key approach used in many European countries and is gaining acceptance throughout North America as knowledge of the environmental benefits and green roof technology grows. While the conditions, benefits and market forces that have driven green roof development in Europe are not identical to Canada's, lessons can be learned from their experiences. Canadian municipalities that are looking to develop and implement green roof policies and programs will need information on how to tailor policies and programs for specific climate conditions, environmental concerns and regulatory realities. In order to provide Canadian municipal decision-makers with an overview of international and local green roof policies and programs, a green roof policy infrastructure manual was recently completed for the Canada Mortgage and Housing Corporation. Decision-makers can be better informed about which policies may be best suited to meet their specific policy needs by reviewing the motivators and other factors behind existing programs around the world. The manual describes green roof policies in each of 12 different jurisdictions from Canada, the United States, Germany, Switzerland, Singapore, and Japan in terms of local green roof motivators and the steps taken along the continuum of establishing policy. This paper described the progress of some Canadian cities that are moving through six phases of establishing appropriate green roof policies and programs. The six phases were introductory and awareness; community engagement; action plan development and implementation; technical research; program and policy development and continuous improvement.

Probabilistic Seismic Hazard Analysis of Victoria, British Columbia, Canada: Considering an Active Leech River Fault

The Leech River fault is situated on Vancouver Island near the city of Victoria, British Columbia, Canada. The 60km transpressional reverse fault zone runs east to west along the southern tip of Vancouver Island, dividing the lithologic units of Jurassic-Cretaceous Leech River Complex schists to the north and Eocene Metchosin Formation basalts to the south. This fault system poses a considerable hazard due to its proximity to Victoria and 3 major hydroelectric dams. The Canadian seismic hazard model for the 2015 National Building Code of Canada (NBCC) considered the fault system to be inactive. However, recent paleoseismic evidence suggests there to be at least 2 surface-rupturing events to have exceeded a moment magnitude (M) of 6.5 within the last 15,000 years (Morell et al. 2017). We perform a Probabilistic Seismic Hazard Analysis (PSHA) for the city of Victoria with consideration of the Leech River fault as an active source. A PSHA for Victoria which replicates the 2015 NBCC estimates is accomplished to calibrate our PSHA procedure. The same seismic source zones, magnitude recurrence parameters, and Ground Motion Prediction Equations (GMPEs) are used. We replicate the uniform hazard spectrum for a probability of exceedance of 2% in 50 years for a 500 km radial area around Victoria. An active Leech River fault zone is then added; known length and dip. We are determining magnitude recurrence parameters based on a Gutenberg-Richter relationship for the Leech River fault from various catalogues of the recorded seismicity (M 2-3) within the fault's vicinity and the proposed paleoseismic events. We seek to understand whether inclusion of an active Leech River fault source will significantly increase the probabilistic seismic hazard for Victoria. Morell et al. 2017.

Canada's energy future : reference case and scenarios to 2030

International Nuclear Information System (INIS)

2007-01-01

Energy is essential to the comfort and economic prosperity of Canadians. This report highlighted some of the issues that Canada faces with respect to its energy future. The report focused on emerging trends in energy supply and demand, and examined various energy futures that may be available to Canadians up to the year 2030. Three different scenarios were presented: (1) a continuing trends scenario; (2) a triple E scenario in which economic, environmental and energy objectives are balanced; and (3) a fortified islands scenario in which security concerns were coupled with international unrest and protectionist governments. The report determined that energy demand will remain a function of population and economic growth. Automobiles will continue to rely on fossil fuels. Energy efficiency will improve in relation to the effectiveness of government policies, and a move towards natural gas alternatives will occur. However, fossil fuels will remain a dominant source of energy supply. Oil sands production grew in all 3 of the evaluated scenarios. It is expected that total natural gas production will decline and imports of liquefied natural gas (LNG) will increase. In all 3 scenarios greenhouse gas (GHG) emissions increased or only slightly declined. A full spectrum of GHG mitigation strategies will need to be implemented so that Canada can meet its target of a 20 per cent reduction in GHGs by 2020. It was concluded that effective policies are needed to optimize Canada's multiple objectives of economic growth, environment sustainability, and development of energy resources. 6 tabs., 118 figs

Bloomer, Raymond, Jr.

2011-12-01

Dr. Edward W. Burke Jr. passed away on June 15, 2011, after suffering a heart attack. Dr. Burke devoted his professional life to the research and teaching of physics and astronomy at King College in Bristol, Tennessee. Edward W. Burke, Jr., was born in Macon, Georgia, on September 16, 1924. He was a Navy veteran, having been commissioned as an ensign in 1944. He served in the Pacific near the end of World War II. He proceeded to complete his undergraduate degree in mathematics from Presbyterian College in 1947 and pursued the M.S. and Ph.D. in physics (1949 and 1954, respectively) at the University of Wisconsin. Under the direction of Professor Julian Mack, his thesis was titled "Isotope Shift in the Spectra of Boron." Although he did research in atomic spectra in the early part of his career, his interest in astronomy and variable stars in particular were his primary interests during his long academic career. Dr. Burke began his illustrious career at King College in 1949. He initiated the astronomy program there in 1950, included constructing a 12.5 inch Newtonian telescope, homemade as was most everything in those days. Many of his students learned about photometry at the Burke Observatory on the college campus. Burke was known for his trips to the Kitt Peak and Lowell observatories accompanied by undergraduate students on his trips, all of which were made by automobile which he preferred over flying. His initial interest in Ap stars later broadened into variable and especially eclipsing binary stars. His motivation was maintained by his desire to have his students experience basic research and to spark their interest in advanced degrees. Numerous students achieved advanced science and medical degrees because of Burke's encouragement and mentoring. In 1959, Dr. Burke was awarded a Fulbright professorship and traveled to Chile where he taught physics for a year in the Engineering School at the University of Chile in Santiago. He worked to establish a physics

In industrial countries, a number of factors put indigenous peoples at increased risk of HIV infection. National surveillance data between 1999 and 2008 provided diagnoses for Aboriginal and Torres Strait Islanders (Australia), First Nations, Inuit and Métis (Canada excluding Ontario and Quebec) and Māori (New Zealand). Each country provided similar data for a non-indigenous comparison population. Direct standardisation used the 2001 Canadian Aboriginal male population for comparison of five-year diagnosis rates in 1999-2003 and 2004-2008. Using the general population as denominators, we report diagnosis ratios for presumed heterosexual transmission, men who have sex with men (MSM) and intravenous drug users (IDU). Age standardised HIV diagnosis rates in indigenous peoples in Canada in 2004-2008 (178.1 and 178.4/100 000 for men and women respectively) were higher than in Australia (48.5 and 12.9/100 000) and New Zealand (41.9 and 4.3/100 000). Higher HIV diagnosis rates related to heterosexual contact among Aboriginal peoples, especially women, in Canada confirm a widening epidemic beyond the conventional risk groups. This potential of a generalised epidemic requires urgent attention in Aboriginal communities; available evidence can inform policy and action by all stakeholders. Although less striking in Australia and New Zealand, these findings may be relevant to indigenous peoples in other countries.

Edward Jenner, who discovered that it is possible to vaccinate against Small Pox using material from Cow Pox, is rightly the man who started the science of immunology. However, over the passage of time many of the details surrounding his astounding discovery have been lost or forgotten. Also, the environment within which Jenner worked as a physician in the countryside, and the state of the art of medicine and society are difficult to appreciate today. It is important to recall that people were still being bled at the time, to relieve the presence of evil humors. Accordingly, this review details Jenner's discovery and attempts to place it in historical context. Also, the vaccine that Jenner used, which decreased the prevalence of Small Pox worldwide in his own time, and later was used to eradicate Small Pox altogether, is discussed in light of recent data.

Edward B. Aveling: the people's Darwin.

Science.gov (United States)

Paylor, Suzanne

2005-06-01

By the late-19th century, evolutionary theory, known by most people as Darwinism, had earned a reputation as an atheistic theory that challenged religious orthodoxy. From recent historical work we now know a great deal about how those with religious convictions received Darwinian ideas, and the role that professional scientists played in styling and communicating 'Darwinism' to the wider public and between themselves. However, relatively little is known about how Darwinian ideas were received and used by avowedly irreligious groups, and how these groups set about communicating their own version of Darwinism to a public hungry for cheap and accessible science. The activities of the Secularist Edward Bibbins Aveling, a prolific popularizer of Darwinian ideas in the late-19th century, offer a unique insight into this relatively uncharted territory. His work helped to develop the polemic of popular irreligious groups and imbue Darwinism with overtly atheistic connotations; it also engendered unprecedented support for atheism from the general public, and challenged the monopoly that some professional scientists enjoyed over imparting serious scientific knowledge to them.

Population Ecology of Caribou Populations without Predators: Southampton and Coats Island Herds

Directory of Open Access Journals (Sweden)

Jean-Pierre Quellet

1996-01-01

Full Text Available This paper is a review of the ecology of two caribou populations inhabiting predator-free northern islands, Coats and Southampton Island. Findings are analyzed in light of the hypothesis that in absence of prédation or high human harvest, food competition results in delayed puberty, reduced calf production, increased winter starvation of caribou and regulates populations at high densities (>2 km-2. Caribou were hunted to extinction on Southampton Island (Northwest Territories, Canada by mid-century. In 1967, 48 caribou were captured on neighbouring Coats Island and released on Southampton Island. Southampton Island is characterized by a high per capita winter food availability in summer and in winter. The population on Southampton Island has been increasing at a rapid rate of growth since re-introduction (Lamba=1.27. Fast population growth was possible because females invested early in reproduction and over winter survival rate was high. The population on Coats Island is also characterized by high per capita food availability in summer but low food availability in winter. The population size has undergone some marked fluctuations, abrupt declines followed by relatively rapid recovery and, contrary to predictions, densities were always less than 1 km-2. Low population densities on Coats Island result primarily from low food availability. This review suggests that in the absence of prédation or high human harvest competition for food regulates caribou population abundance. However, caribou numbers can fluctuate markedly among years because inter-annual variation of weather conditions affects forage accessibility in winter. This review also emphasizes the importance of distinguishing between factors that determine absolute population density and variation in density among years (in our case probably plant production and winter weather conditions which influence forage accessibility from the regulatory factors, processes that stop population

Neotectonic investigations in Southern Ontario. Prince Edward County - Phase 2

1991-06-01

This report summarizes the preliminary results of geological and geophysical investigations and offshore side scan sonar surveys of the bedrock and unconsolidated sediments in Prince Edward County, Southern Ontario, by the Ontario Geological Survey in 1989. Investigations were focused on deformations in the bedrock and the surficial deposits. Some of these deformations may be neotectonic in origin. Low magnitude seismicity in the Prince Edward County region appears to be spatially related to a major regional fault system that crosses Lake Ontario and consists of the seismically active Clarendon-Linden Fault System in New York State, the Picton-Napanee and Rideau Faults, the Frontenac-Sharbot Lake Terrane Boundary and the assumed Salmon River Fault in Ontario. Detailed observations were made in the Long Point study area and the Mountain View and Picton Quarries. Bedrock structural features were documented, including: joints; normal, reverse and strike strip faults; brittle folds; and Jurassic age ultramafic dyke. Detailed refraction seismic surveys were conducted across a local fault and possible fold structures. Magnetic surveys, conducted in conjunction with the offshore side scan sonar surveys, documented large magnetic anomalies southeast of Point Petre and at the northeast end of Long Reach. Side scan sonar surveys of the lake bottom to the east of Point Petre confirm the presence of pop-ups in that area of the lake bottom which is immediately adjacent to where pop-ups are observed on land. The pop-ups present in the lake bottom have similar orientations to those mapped in the study area

Geologic framework and hydrogeologic characteristics of the outcrops of the Edwards and Trinity aquifers, Medina Lake area, Texas

Science.gov (United States)

Small, Ted A.; Lambert, Rebecca B.

1998-01-01

The hydrogeologic subdivisions of the Edwards aquifer outcrop in the Medina Lake area in Medina and Bandera Counties generally are porous and permeable. The most porous and permeable appear to be hydrogeologic subdivision VI, the Kirschberg evaporite member of the Kainer Formation; and hydrogeologic subdivision III, the leached and collapsed members, undivided, of the Person Formation. The porosity of the rocks in the Edwards aquifer outcrop is related to depositional or diagenetic elements along specific stratigraphic horizons (fabric selective) and to dissolution and structural elements that can occur in any lithostratigraphic horizon (not fabric selective). Permeability depends on the physical properties of the rock such as size, shape, and distribution of pores.

The Italian Job: Giambattista Vico at the Origin of Edward Said’s Humanism

Directory of Open Access Journals (Sweden)

Mauro Scalercio

2016-08-01

Full Text Available The aim of this paper is twofold. First, it will try to clarify the importance of the Italian philosopher Giambattista Vico (1668-1744 in shaping Edward Said’s categories. Second, it will shed light on the theoretical importance of such genealogy. From the philological point of view, it is important to show how profound Said’s knowledge of Vico’s work is. Therefore, this paper will follow references to Vico within the whole of Said’s work, from late the sixties ones to the posthumous Humanism and Democratic Criticism. As far as theory is concerned, understanding Said’s use of Vico’s concepts explains why Said refers to his own work with the controversial term “humanism.” Vico, critiquing modernity from the onset, is the basis on which Said built a new critical humanism. In particular, Said uses the very essential elements of the philosophy of Vico: the importance of body as the source of humanity, the critique of modern abstractions, the idea that man knows what he makes, and the idea of the historicity of every human invention and construction.   Keywords: Edward Said; Vico; Humanism; Modernity; Historicity; Facticity.

Canada, while professing a non-nuclear policy for its own armed forces, is, none the less, a member of a nuclear alliance. The security gained through participation in such arrangements does not come cost-free, despite the common view that countries such as Canada enjoy a free ride. Being under the nuclear umbrella, as this paper seeks to illustrate, does generate its own problems and costs. For example, does influence stem from the actual possession of nuclear weapons (albeit under US control), from support of the concept of nuclear deterrence and its infrastructure, or from possessing territory that is of strategic importance to a more powerful ally? Does the Canadian experience serve as a model for countries that are in close proximity to an existing or threshold nuclear power? Much depends on the willingness of a country to participate in the nuclear infrastructure associated with the acquisition of nuclear weapons for security purposes. It must accept the underlying rationale or logic of nuclear deterrence and the constraints on alternative security options that this imposes and it must also recognize that reliance on nuclear deterrence for military security seven if one seeks to emulate Canada and become a non-nuclear weapon state in a nuclear alliance can produce strains in its own right. The case of Canada shows that a country seeking security through such means should be aware of, and reflect upon, the fact that what appears to be a free ride does not come free of charge. However, a country may have other options in it, military security that have neither historically or geostrategically been available to Canada

A permanent pacemaker is frequently needed after transcatheter aortic valve implantation, but the available data are mainly on the CoreValve system. To evaluate the need for new permanent pacemaker after implantation of the Edwards Sapien device, as well as related factors. We included the first 100 patients treated with the Edwards Sapien device at our institution. Of these, 12 had a permanent pacemaker before the procedure, and thus our study population was the remaining 88 patients. A permanent pacemaker was indicated in eight patients (9.1%) during hospitalization or at 30 days. After discharge, another four patients needed a pacemaker (at 42 days and three, 18, and 30 months). Two variables were associated with the need for pacemaker during hospitalization: previous dialysis (13% vs. 1%, p=0.042) and complete right bundle branch block before the procedure (25% vs. 5%, p=0.032). More than one month after the procedure, the characteristics associated with the need for pacemaker were plasma creatinine level (2.5±1.7 vs. 1.3±0.6 mg/dl, p=0.001) and previous myocardial infarction (50% vs. 10%, p=0.013). The rate of pacemaker implantation with the Edwards Sapien device was 9.1%. Right bundle branch block and dialysis were associated with this complication.

Terrorism in Canada.

Science.gov (United States)

Kollek, Daniel

2003-01-01

This paper reviews terrorism in Canada, assessing the incidence and nature of terrorist activity, the potential targets of terrorist attacks, risk factors to Canadian nationals and institutions, and the responses of the Canadian government in dealing with the threat and the effectiveness of those responses. Despite the fact that there have been no recent high-profile terrorist events in Canada, this country has a serious terrorism problem, the key manifestation of which is the multitude of terrorist organizations that have designated Canada as a base of operations. In addition, Canadians have been attacked overseas and Canadian organizations, both local and abroad, are potential targets of terrorist activity. Canadian attempts to deal with terrorism through foreign and domestic policy have been ineffective, primarily because the policies have been poorly enforced. Until recently, terrorist organizations legally could raise funds in Canada, in direct contravention of international treaties signed by Canada. It is possible that the ineffectiveness in enforcing the anti-terrorism legislation stems from hope that placating terrorist organizations, and the countries that support them, will prevent Canada from becoming a target. Unfortunately evidence from other countries has shown this strategy to be ineffective.

MD-11 PCA - First Landing at Edwards

Science.gov (United States)

1995-01-01

This McDonnell Douglas MD-11 approaches the first landing ever of a transport aircraft under engine power only on Aug. 29, 1995, at NASA's Dryden Flight Research Center, Edwards, California. The milestone flight, flown by NASA research pilot and former astronaut Gordon Fullerton, was part of a NASA project to develop a computer-assisted engine control system that enables a pilot to land a plane safely when it normal control surfaces are disabled. The Propulsion-Controlled Aircraft (PCA) system uses standard autopilot controls already present in the cockpit, together with the new programming in the aircraft's flight control computers. The PCA concept is simple--for pitch control, the program increases thrust to climb and reduces thrust to descend. To turn right, the autopilot increases the left engine thrust while decreasing the right engine thrust. The initial Propulsion-Controlled Aircraft studies by NASA were carried out at Dryden with a modified twin-engine F-15 research aircraft.

One of the positive means to solve urgent problems in the field of professional education is not only systematization of the information, but also the creative accumulation and assimilation of the cultural experience and, as a result, of the scientific, artistic-design, project-constructive and/or technological principles of activities. The high standards to the future teachers’ professional education are caused by the binary character of the future activities: the teacher should be both a professional and a pedagogue. The transformation of the professional education, while there are lots of global challenges in the world, leads to the activation of the creative potential of the future pedagogue at a professional educational institution. The goal of this article is to analyze systems of thinking suggested by Edward de Bono, and to attempt implementing partially these approaches into strategic thinking in the field of professional education, i.e. in the future teachers’ sewing specialization at a professional educational institution. According to the goal of the article, the whole complex of scientific approaches and methods has been used at the different theoretical and empirical levels. The systemic approach is in the core of the research, following the idea of the integrity of thinking expressed by Edward de Bono and of mechanisms which facilitate it. At the moment in our volatile world there is a clear need in new type of thinking – creative and constructive, which allows to form new ideas and ways for development. The system of such a kind of thinking was developed by Edward de Bono. According to him, the main method for the process of problem solving should be: refusal from cliché and established patters of thinking; perception of the problem with humor; continuous questioning of permissiveness; change in the way of seeking for information; creation of integral

This fact sheet highlights findings from the vulnerability study of a public-supply well field in San Antonio, Texas. The well field consists of six production wells that tap the Edwards aquifer. Typically, one or two wells are pumped at a time, yielding an average total of 20-21 million gallons per day. Water samples were collected from public-supply wells in the well field and from monitoring wells installed along general directions of flow to the well field. Samples from the well field contained some constituents of concern for drinking-water quality, including nitrate; the pesticide compounds atrazine, deethylatrazine, and simazine; and the volatile organic compounds tetrachloroethene (also called perchloroethene, or PCE), chloroform, bromoform, and dibromochloromethane. These constituents were detected in untreated water at concentrations much less than established drinking-water standards, where such standards exist. Overall, the study findings point to four primary factors that affect the movement and fate of contaminants and the vulnerability of the public-supply well field in San Antonio, Texas: (1) groundwater age (how long ago water entered, or recharged, the aquifer), (2) fast pathways for flow of groundwater through features formed or enlarged by dissolution of bedrock, (3) recharge characteristics of the aquifer, and (4) natural geochemical processes within the aquifer. A computer-model simulation of groundwater flow and transport was used to estimate the traveltime (or age) of water particles entering public-supply well W4 in the well field. Modeled findings show that almost half of the water reaching the public-supply well is less than 2 years old. Such a large percentage of very young water indicates that (1) contaminants entering the aquifer may be transported rapidly to the well, (2) there is limited time for chemical reactions to occur in the aquifer that may attenuate contaminants, and (3) should recharge water become contaminated with

Three new species of Pseudosmittia Edwards from the Neotropical region, P. satheri, P. larga and P. trapezoidea, are described and figured as males. Allocladiusfortispinatus (Edwards), A. globosus Andersen et al. and A. quadrus Andersen et al. are redescribed on the basis of new material and their geographical distribution updated. A phylogenetic analysis was performed in order to assess the phylogenetic relationships of the new species. As a result, the species P. sœtheri and P. larga are found to be sister species belonging to the angusta group. The species P. trapezoidea is the sister group of the clade ((P. propetropis (P. tropis--P. lamellata)) and belongs to the brevifurcata group sensu lato.

Progress on the NEPTUNE Canada Seismograph Network

NEPTUNE Canada is the world's first deep-sea regional multi-disciplinary scientific cabled ocean observatory. In the fall of 2007 an 800 kilometer ring of powered fiber optic cable was laid on the seafloor over the northern part of the Juan de Fuca plate and connected to a shore facility near Port Alberni on Vancouver Island. In September 2009, three broadband OBS packages were deployed in the form of a large triangle with apexes at mid plate near ODP 1027 (water depth of 2654m) and two sites on the continental slope, near ODP 889 (1256m) and Barkley Canyon (396m). The broadband systems comprise a broadband seismometer and strong motion accelerometer in a spherical titanium case surficially buried in a caisson backfilled with glass beads. Noise levels observed are as expected with the spectra being similar to, or quieter than, coastal seismograph stations in approximately the 10 to 20 second period range. The OBS's have higher noise levels at longer periods where ocean swells and the resultant infragravity waves dominate the noise spectra, and in the 1-10 Hz bandwidth typically used for locating local earthquakes. The shallowest site at Barkley Canyon has the highest noise levels. A small array, about 6 km in maximum dimension, is under construction on the Endeavour segment of the Juan de Fuca Ridge to record earthquake activity in the vicinity of the many NEPTUNE Canada multi-disciplinary ridge experiments. Two short period instruments were installed there in 2010. A broadband instrument and two additional short period instruments are planned to complete the initial ridge array. Even though the NEPTUNE Canada seismograph network is not yet complete, measured by the use of its data, it is a success already. The data are routinely used along with data from land seismographs of the Canadian National Seismograph Network for locating earthquakes in the region. However, the smallest seismic arrivals picked on the land stations cannot be routinely picked on the OBS

Canada's uranium policies

International Nuclear Information System (INIS)

Smith, K.L.; Williams, R.M.

1991-01-01

The purpose of this paper is to provide an update on the Canadian Government policies which affect the uranium industry and, where appropriate, to provide some background on the development of these policies. This review is timely because of two recent announcements by the Minister of Energy, Mines and Resources - one concerning the Canadian Government's renewed commitment to maintain the nuclear power option for Canada, and the other concerning some adjustments to Canada's uranium export policy. The future of Canada's nuclear industry was subject to a thorough review by the Canadian Government during 1989. This review occurred at a time when environmental issues were attracting increasing attention around the world, and the environmental advantages of nuclear power were becoming increasingly recognised. The strong support for the nuclear industry in Canada is consistent with the government's long-standing efforts to maintain Canada's position as a reliable and competitive supplier of uranium. This paper is particularly devoted to an outline of the results of the uranium export policy review. (author)

Uranium in Canada

International Nuclear Information System (INIS)

1987-09-01

Canadian uranium exploration and development efforts in 1985 and 1986 resulted in a significant increase in estimates of measured uranium resources. New discoveries have more than made up for production during 1985 and 1986, and for the elimination of some resources from the overall estimates, due to the sustained upward pressure on production costs and the stagnation of uranium prices in real terms. Canada possesses a large portion of the world's uranium resources that are of current economic interest and remains the major focus of inter-national uranium exploration activity. Expenditures for uranium exploration in Canada in 1985 and 1986 were $32 million and $33 million, respectively. Although much lower than the $130 million total reported for 1979, expenditures for 1987 are forecast to increase. Exploration and surface development drilling in 1985 and 1986 were reported to be 183 000 m and 165σ2 000 m, respectively, 85 per cent of which was in Saskatchewan. Canada has maintained its position as the world's leading producer and exporter of uranium. By the year 2000, Canada's annual uranium requirements will be about 2 100 tU. Canada's known uranium resources are more than sufficient to meet the 30-year fuel requirements of those reactors in Canada that are either in operation now or expected to be in service by the late 1990s. A substantial portion of Canada's identified uranium resources is thus surplus to Canadian needs and available for export. Annual sales currently approach $1 billion, of which exports account for 85 per cent. Forward domestic and export contract commitments totalled 73 000 tU and 62 000 tU, respectively, as of early 1987

Uranium in Canada

International Nuclear Information System (INIS)

1985-09-01

In 1974 the Minister of Energy, Mines and Resources (EMR) established a Uranium Resource Appraisal Group (URAG) within EMR to audit annually Canada's uranium resources for the purpose of implementing the federal government's uranium export policy. A major objective of this policy was to ensure that Canadian uranium supplies would be sufficient to meet the needs of Canada's nuclear power program. As projections of installed nuclear power growth in Canada over the long term have been successively revised downwards (the concern about domestic security of supply is less relevant now than it was 10 years ago) and as Canadian uranium supply capabilities have expanded significantly. Canada has maintained its status as the western world's leading exporter of uranium and has become the world's leading producer. Domestic uranium resource estimates have increased to 551 000 tonnes U recoverable from mineable ore since URAG completed its last formal assessment (1982). In 1984, Canada's five primary uranium producers employed some 5800 people at their mining and milling operations, and produced concentrates containing some 11 170 tU. It is evident from URAG's 1984 assessment that Canada's known uranium resources, recoverable at uranium prices of $150/kg U or less, are more than sufficient to meet the 30-year fuelling requirements of those reactors that are either in opertaion now or committed or expected to be in-service by 1995. A substantial portion of Canada's identified uranium resources, recoverable within the same price range, is thus surplus to Canadian needs and available for export. Sales worth close to $1 billion annually are assured. Uranium exploration expenditures in Canada in 1983 and 1984 were an estimated $41 million and $35 million, respectively, down markedly from the $128 million reported for 1980. Exploration drilling and surface development drilling in 1983 and 1984 were reported to be 153 000 m and 197 000 m, respectively, some 85% of which was in

Canada goose nest survival at rural wetlands in north-central Iowa

The last comprehensive nest survival study of the breeding giant Canada goose (Branta canadensis maxima) population in Iowa, USA, was conducted >30 years ago during a period of population recovery, during which available nesting habitat consisted primarily of artificial nest structures. Currently, Iowa's resident goose population is stable and nests in a variety of habitats. We analyzed the effects of available habitat on nest survival and how nest survival rates compared with those of the expanding goose population studied previously to better understand how to maintain a sustainable Canada goose population in Iowa. We documented Canada goose nest survival at rural wetland sites in north-central Iowa. We monitored 121 nests in 2013 and 149 nests in 2014 at 5 Wildlife Management Areas (WMAs) with various nesting habitats, including islands, muskrat (Ondatra zibethicus) houses, and elevated nest structures. We estimated daily nest-survival rate using the nest survival model in Program MARK. Survival was influenced by year, site, stage, presence of a camera, nest age, and an interaction between nest age and stage. Nest success rates for the 28-day incubation period by site and year combination ranged from 0.10 to 0.84. Nest survival was greatest at sites with nest structures (β = 17.34). Nest survival was negatively affected by lowered water levels at Rice Lake WMA (2013 β = −0.77, nest age β = −0.07). Timing of water-level drawdowns for shallow lake restorations may influence nest survival rates.

The risk of stranded assets for utilities in Canada

International Nuclear Information System (INIS)

Schroeder, W.

1998-01-01

The problems of dealing with stranded assets in Canada and the United States were discussed. Compared to the United States, the risk associated with stranded assets for utilities in Canada was considered to be relatively low because of the following factors: (1) low variable cost, (2) isolation, (3) lack of transmission interconnection capacity, (4) lack of tight synchronization in North America, (5) the likelihood of an increase in natural gas prices, (6) the absence of jurisdictional disputes such as FERC versus the states, (7) social considerations, (8) the learning curve, (9) politics, (10) weak balance sheets, (11) relatively low electricity prices, (12) the weak Canadian dollar, and (13) the possibility of refinancing at lower interest rates. Ontario Hydro, New Brunswick and Nova Scotia Power are the three Canadian utilities that may have stranded costs. For Ontario Hydro and New Brunswick Power the stranded costs would be related to nuclear generator problems, whereas for Nova Scotia Power, the stranded costs would be related to the thermal generating base, the threat from Sable Island Gas and the changing tax structure of the utility. Some other reasons why stranded assets could be created in Canada would include low variable costs and high fixed costs, over capacity of at least 30 per cent in generation, limited domestic energy growth, competitive threat from gas, reliability and safety of nuclear plants, and technology change. Five factors in terms of which stranded assets can be expressed are: (1) variable cost definition, (2) total cost definition, (3) operating profit definition, (4) wide geographic definition, and (5) free market definition. In calculating stranded assets, the number of years over which the assets are recovered and the discount rate are considered to be key factors. 26 tabs

Noel, Marie; Dangerfield, Neil; Hourston, Roy A.S.; Belzer, Wayne; Shaw, Pat; Yunker, Mark B.; Ross, Peter S.

2009-01-01

In order to distinguish between 'local' and 'background' sources of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in coastal British Columbia (Canada) air, we collected samples from two sites: a remote site on western Vancouver Island, and a near-urban site in the Strait of Georgia. Seasonally-integrated samples of vapor, particulate, and rain were collected continuously during 365 days for analysis of 275 PCB and PBDE congeners. While deposition of the legacy PCBs was similar at both sampling sites, deposition of PBDEs at the remote site amounted to 42% (10.4 mg/ha/year) of that at the near-urban site. Additional research into atmospheric circulation in the NE Pacific Ocean will provide more insight into the transport and fate of priority pollutants in this region, but trans-Pacific delivery of PBDEs to the west coast of North America may underlie in part our observations. For example, approximately 40% of >12,000 ten-day back trajectories calculated for the remote site originated over Asia, compared to only 2% over North America. - Legacy PCBs and current-use PBDEs are dispersed through atmospheric processes in coastal British Columbia, Canada.

2004-01-01

In this paper, we present the first comprehensive long-term record of preanthropogenic rates of atmospheric mercury accumulation in dated peat deposits for the High Arctic of Canada. Geochemical studies of two peat hummocks from Bathurst Island, Nunavut reveal substantial inputs from soil dust...... (titanium), marine aerosols (bromine), and mineral-water interactions (uranium). Mercury, however, was supplied to these peat mounds exclusively by atmospheric deposition. Mercury concentration measurements and age dating of the peat profiles indicate rather constant natural "background" mercury flux of ca....... 1 microgram per square meter per year from 5900 to 800 calibrated years BP. These values are well within the range of the mercury fluxes reported from other Arctic locations, but also by peat cores from southern Canada that provide a record of atmospheric Hg accumulation extending back 8000 years...

17α-ethynylestradiol (EE2), a synthetic estrogen prescribed as a contraceptive, was measured in Shorthead Redhorse Suckers (ShRHSs) (Moxostoma macrolepidotum) collected near a wastewater treatment plant (WWTP) in the St. Clair River (Ontario, Canada). We detected EE2 in 50% of the fish samples caught near the WWTP (Stag Island), which averaged 1.6 ± 0.6 ng/g (wet weight) in males and 1.43 ± 0.96 ng/g in females. No EE2 was detected in the samples from the reference site (Port Lambton) which was 26 km further downstream of the Stag Island site. Only males from Stag Island had VTG induction, suggesting the Corunna WWTP effluent as a likely source of environmental estrogen. EE2 concentrations were correlated with total body lipid content (R 2 = 0.512, p 15 N (R 2 = 0.436, p < 0.05, n = 10), suggesting higher EE2 exposures in carnivores. Our data support the hypothesis of EE2 bioaccumulation in wild fish. - Ethinylestradiol accumulation in wild fish.

Tom JONES

2009-04-01

Full Text Available The purpose of the study was to investigate the potential impact of distance education on a small, rural, Canadian island community. Presently, the population of small, rural island communities on the west coast of Canada are facing numerous challenges to retain and to attract permanent residents and families and to provide support and direction for those residents who wish to pursue K-12 accreditation, post-secondary education, vocational/trades training and up-grading or life-long learning. A unique set of considerations confront many of these isolated communities if they wish to engage in distance education and training. This set ranges from internet access to excessive travel by secondary students to the lack of centralized facility. For this study, a group of 48 participants were interviewed to determine their perceptions of the potential for distance education to impact on the community's educational, both academic and vocational, life-long learning and economic needs. The results indicated that there were four general areas of purported benefit: academic advancement, an improved quality of life, support for young families and a stabilizing affect on the local economy. Suggestions for the implementation of a suitable distance education resource are noted.

We document an established population of blacklegged ticks, Ixodes scapularis, on Corkscrew Island, Kenora District, Ontario, Canada. Primers of the outer surface protein A (OspA) gene, the flagellin (fla) gene, and the flagellin B (flaB) gene were used in the PCR assays to detect Borrelia burgdorferi sensu lato (s.l.), the Lyme disease bacterium. In all, 60 (73%) of 82 adult I. scapularis, were infected with B. burgdorferi s.l. As well, 6 (43%) of 14 unfed I. scapularis nymphs were positive for B. burgdorferi s.l. An I. scapularis larva was also collected from a deer mouse, and several unfed larvae were gathered by flagging leaf litter. Based on DNA sequencing of randomly selected Borrelia amplicons from six nymphal and adult I. scapularis ticks, primers for the flagellin (fla) and flagellin B (flaB) genes reveal the presence of B. burgdorferi sensu stricto (s.s.), a genospecies pathogenic to humans and certain domestic animals. We collected all 3 host-feeding life stages of I. scapularis in a single year, and report the northernmost established population of I. scapularis in Ontario. Corkscrew Island is hyperendemic for Lyme disease and has the highest prevalence of B. burgdorferi s.l. for any established population in Canada. Because of this very high infection prevalence, this population of I. scapularis has likely been established for decades. Of epidemiological significance, cottage owners, island visitors, outdoors enthusiasts, and medical professionals must be vigilant that B. burgdorferi s.l.-infected I. scapularis on Corkscrew Island pose a serious public health risk.

Grassberger, Peter; Dhar, Deepak; Mohanty, P. K.

2016-10-01

We present simulations of the one-dimensional Oslo rice pile model in which the critical height at each site is randomly reset after each toppling. We use the fact that the stationary state of this sand-pile model is hyperuniform to reach system of sizes >107 . Most previous simulations were seriously flawed by important finite-size corrections. We find that all critical exponents have values consistent with simple rationals: ν =4/3 for the correlation length exponent, D =9/4 for the fractal dimension of avalanche clusters, and z =10/7 for the dynamical exponent. In addition, we relate the hyperuniformity exponent to the correlation length exponent ν . Finally, we discuss the relationship with the quenched Edwards-Wilkinson model, where we find in particular that the local roughness exponent is αloc=1 .

Filming Critical Female Perspectives: Edward Yang’s The Terrorizers

Directory of Open Access Journals (Sweden)

Kai-man Chang

2017-04-01

Full Text Available From his first film—a twenty-minute short, “Expectations” (1982—to his last—a three-hour masterpiece, 'Yi Yi' (2000—Edward Yang, one of the leading figures of the Taiwan New Cinema movement, devoted his career to portraying the impact of neoliberal capitalism on the lives of the citizens of Taipei. Interestingly, Yang’s films often employ female perspectives to criticize Taiwan’s education system and transnational corporations for perpetuating neoliberal capitalism’s ideology of self-fulfillment and upward mobility. This paper draws upon feminist film theory to investigate the ways in which Yang’s third feature, 'The Terrorizers' (1986, utilizes various innovative cinematic languages to engender a multitude of women’s perspectives to expose male voyeurism and ultimately criticize the impact of neoliberal capitalism in Taipei.

Arctic Islands LNG

Energy Technology Data Exchange (ETDEWEB)

Hindle, W.

1977-01-01

Trans-Canada Pipe Lines Ltd. made a feasibility study of transporting LNG from the High Arctic Islands to a St. Lawrence River Terminal by means of a specially designed and built 125,000 cu m or 165,000 cu m icebreaking LNG tanker. Studies were made of the climatology and of ice conditions, using available statistical data as well as direct surveys in 1974, 1975, and 1976. For on-schedule and unimpeded (unescorted) passage of the LNG carriers at all times of the year, special navigation and communications systems can be made available. Available icebreaking experience, charting for the proposed tanker routes, and tide tables for the Canadian Arctic were surveyed. Preliminary design of a proposed Arctic LNG icebreaker tanker, including containment system, reliquefaction of boiloff, speed, power, number of trips for 345 day/yr operation, and liquefaction and regasification facilities are discussed. The use of a minimum of three Arctic Class 10 ships would enable delivery of volumes of natural gas averaging 11.3 million cu m/day over a period of a year to Canadian markets. The concept appears to be technically feasible with existing basic technology.

Late Miocene mollusks from the Queen Charlotte Islands, British Columbia, Canada

Science.gov (United States)

Addicott, Warren O.

1978-01-01

A fauna of bivalve mollusks, scattered gastropods, and an echinoid from exposures of the Skonun Formation in the northeastern part of Graham Island is indicative of an early late Miocene age and correlation with the provincial Wishkahan Stage. The molluscan assemblages are from the upper 600 of the 1800-m-thick marine and nonmarine formation, which appears to be entirely of late Miocene age. The Skonun Formation is the strandline fa.cies of marginal marine and nonmarine deposits of the northwestern part of the Queen Charlotte basin, a Nieogene embayment paralleling the modern mainland coast. The molluscan fauna and associated lignite beds are known from a few widely scattered outcrops; they are indicative of alternating marine and nonmarine to brackish-water environments in the upper part of the formation. The Skonun fauna occurs near the northern boundary of the Pacific Northwest Neogene molluscan province. It is the only marine Neogene molluscan fauna known from the British Columbia coast. The fauna has strong taxonomic ties with the fauna of the Empire Formation of southwestern Oregon and has several species in common with the upper Miocene of the Lituya district, southeastern Alaska, implying that these three faunas are coeval.

Addressing Household Food Insecurity in Canada - Position Statement and Recommendations - Dietitians of Canada.

Science.gov (United States)

2016-09-01

POSITION STATEMENT It is the position of Dietitians of Canada that household food insecurity is a serious public health issue with profound effects on physical and mental health and social well-being. All households in Canada must have sufficient income for secure access to nutritious food after paying for other basic necessities. Given the alarming prevalence, severity and impact of household food insecurity in Canada, Dietitians of Canada calls for a pan-Canadian, government-led strategy to specifically reduce food insecurity at the household level, including policies that address the unique challenges of household food insecurity among Indigenous Peoples. Regular monitoring of the prevalence and severity of household food insecurity across all of Canada is required. Research must continue to address gaps in knowledge about household vulnerability to food insecurity and to evaluate the impact of policies developed to eliminate household food insecurity in Canada. Dietitians of Canada recommends: Development and implementation of a pan-Canadian government-led strategy that includes coordinated policies and programs, to ensure all households have consistent and sufficient income to be able to pay for basic needs, including food. Implementation of a federally-supported strategy to comprehensively address the additional and unique challenges related to household food insecurity among Indigenous Peoples, including assurance of food sovereignty, with access to lands and resources, for acquiring traditional/country foods, as well as improved access to more affordable and healthy store-bought/market foods in First Nation reserves and northern and remote communities. Commitment to mandatory, annual monitoring and reporting of the prevalence of marginal, moderate and severe household food insecurity in each province and territory across Canada, including among vulnerable populations, as well as regular evaluation of the impact of poverty reduction and protocols for

Sexual portraits: Edward Melcarth and homoeroticism in modern American art.

Science.gov (United States)

Griffey, Erin; Reay, Barry

2012-01-01

Although one will not find Edward Melcarth (1914-73) in the best recent histories of male homosexuality and American art, he was not always so spectral. Named in Life magazine in 1950 as one of the best young American artists, he exhibited as a painter, draftsman and sculptor and also practised as an illustrator, photographer and designer. His work survives in the Forbes Collection, in the Smithsonian Institution and in the art archives at the Kinsey Institute. We argue that Melcarth’s vision of the erotic was far broader than the traditional categories of sexuality that are perpetuated in art histories of homoeroticism in modern America – and that such a revisioning enables a reinterpretation of some of the better known images of homosexual art.

Multidecadal shoreline changes of atoll islands in the Marshall Islands

Science.gov (United States)

Ford, M.

2012-12-01

Atoll islands are considered highly vulnerable to the impacts of continued sea level rise. One of the most commonly predicted outcomes of continued sea level rise is widespread and chronic shoreline erosion. Despite the widespread implications of predicted erosion, the decadal scale changes of atoll island shorelines are poorly resolved. The Marshall Islands is one of only four countries where the majority of inhabited land is comprised of reef and atoll islands. Consisting of 29 atolls and 5 mid-ocean reef islands, the Marshall Islands are considered highly vulnerable to the impacts of sea level rise. A detailed analysis of shoreline change on over 300 islands on 10 atolls was undertaken using historic aerial photos (1945-1978) and modern high resolution satellite imagery (2004-2012). Results highlight the complex and dynamic nature of atoll islands, with significant shifts in shoreline position observed over the period of analysis. Results suggest shoreline accretion is the dominant mode of change on the islands studied, often associated with a net increase in vegetated island area. However, considerable inter- and intra-atoll variability exists with regards to shoreline stability. Findings are discussed with respect to island morphodynamics and potential hazard mitigation and planning responses within atoll settings.

At 0820 PST on 28 March 1979, the Department of Energy's Emergency Operations Center advised the Atmospheric Release Advisory Capability (ARAC) that the Three Mile Island nuclear power plant in Harrisburg, Pennsylvania, had experienced an accident some four hours earlier, resulting in the atmospheric release of xenon-133 and krypton-88. This report describes ARAC's response to the Three Mile Island accident, including the role ARAC played throughout the 20 days that real-time assessments were made available to the Department of Energy on-scene commander. It also describes the follow-up population-dose calculations performed for the President's Commission on Three Mile Island. At the request of the Nuclear Regulatory Commission, a questionnaire addressing the usefulness of ARAC products during the accident was sent to ARAC-product users. A summary of the findings from this questionnaire, along with recommendations for improving ARAC service, is also presented. The accident at Mississauga, Ontario, Canada, is discussed in the context of a well-planned emergency response by local and Federal officials

Canada's nuclear power programme

International Nuclear Information System (INIS)

Peden, W.

1976-01-01

Although Canada has developed the CANDU type reactor, and has an ambitious programme of nuclear power plant construction, there has been virtually no nuclear controversy. This progress was seen as a means to bring Canada out of the 'resource cow' era, and onto a more equal footing with technologically elite nations. However the Indian nuclear explosion test, waste storage problems, contamination problems arising from use of uranium ore processing waste as land fill and subsidised sale of nuclear power plants to Argentina and South Korea have initiated public and parliamentary interest. Some economists have also maintained that Canada is approaching over-supply of nuclear power and over-investment in plant. Canada has no official overall energy production plan and alternative sources have not been evaluated. (JIW)

The Great Basin Canada goose in southcentral Washington: A 40-year nesting history

Fitzner, R.E.; Rickard, W.H.; Eberhardt, L.E.; Gray, R.H.

1991-04-01

Overall, the nesting population of Great Basin Canada geese (Branta canadensis moffitti) on the Hanford Site in southcentral Washington State is doing well and appears to be increasing. The average annual total nests for the period 1981 through 1990 was 215 nests, which is slightly above the average reported for the period 1950 through 1970. The nesting population has shifted its nucleus from upriver islands (1--10) to the lower river islands (11--20) with over 70% of the present-day nesting occurring on Islands 17, 18, 19, 20. The annual percent-successful nests from 1981 through 1990 was 80%. This is above the 71% reported for 1950 to 1970, but is below the 82% reported for 1971 to 1980. Average annual clutch size for 1981 to 1990 was 6.05, which is above the 1971-to-1980 average of 5.6 and the 1950-to-70 average of 5.5. Next desertions for 1981 to 1990 averaged 8%. This rate is well below the 14% reported for 1950 to 1970. Predators were responsible for an annual predation rate of 9% from 1981 to 1990. This is below the 1950-to-1970 annual average predation rate of 14%. Flooding losses to nests were low during the 1980s, except for 1989 and 1990 when 6% and 9% of the total nests, respectively, were destroyed by flooding. 9 refs., 4 figs., 1 tab

1999-01-01

Financial information from TransCanada PipeLines Limited and a review of the company's 1998 operations was made available for the benefit of shareholders. TransCanada's pipeline system transports natural gas and crude oil from Western Canada Sedimentary Basin to North America's major energy markets. Net earnings from continuing operations for 1998, before unusual charges, were $575 million ($ 355 million after unusual charges) compared to $522 million for 1997. Solid performances from the energy transmission and international business, when compared to 1997, were more than offset by a decreased contribution from energy processing. TransCanada recorded integration costs of $166 million, after tax, related to the merger with NOVA in 1998, which was the major operational accomplishment during the year, creating a seamless economic energy delivery, processing and marketing system from the wellhead to the market. tabs., figs

Status, population fluctuations and ecological relationships of Peary caribou on the Queen Elizabeth Islands: Implications for their survival

Directory of Open Access Journals (Sweden)

Frank L. Miller

2003-04-01

Full Text Available The Peary caribou (Rangifer tarandus pearyi was recognized as 'Threatened' by the Committee on the Status of Endangered Wildlife in Canada in 1979 and 'Endangered' in 1991. It is the only member of the deer family (Cervidae found on the Queen Elizabeth Islands (QEI of the Canadian High Arctic. The Peary caribou is a significant part of the region's biodiversity and a socially important and economically valuable part of Arctic Canada's natural heritage. Recent microsatellite DNA findings indicate that Peary caribou on the QEI are distinct from caribou on the other Arctic Islands beyond the QEI, including Banks Island. This fact must be kept in mind if any translocation of caribou to the QEI is proposed. The subspecies is too gross a level at which to recognize the considerable diversity that exists between Peary caribou on the QEI and divergent caribou on other Canadian Arctic Islands. The Committee on the Status of Endangered Wildlife in Canada should take this considerable diversity among these caribou at below the subspecies classification to mind when assigning conservation divisions (units to caribou on the Canadian Arctic Islands. In summer 1961, the first and only nearly range-wide aerial survey of Peary caribou yielded a population estimate on the QEI of 25 845, including about 20% calves. There was a strong preference for range on the western QEI (WEQI, where 94% (24 363 of the estimated caribou occurred on only 24% (ca. 97 000 km2 of the collective island-landmass. By summer 1973, the overall number of Peary caribou on the QEI had decreased markedly and was estimated at about 7000 animals. The following winter and spring (1973-74, the Peary caribou population declined 49% on the WQEI. The estimated number dropping to <3000, with no calves seen by us in summer 1974. Based on estimates from several aerial surveys conducted on the WQEI from 1985 to 1987, the number of Peary caribou on the QEI as a whole was judged to be 3300-3600 or only

The aim of this study was to determine the characteristics of women in Canada who received care from a midwife during their prenatal period. The findings of this study were drawn from the Maternity Experiences Survey (MES), which was a cross-sectional survey that assessed the experiences of women who gave birth between November 2005 and May 2006. The main outcome variable for this study was the prenatal care provider (i.e. midwife versus other healthcare providers). Demographic, socioeconomic, as well as health and pregnancy factors were evaluated using bivariate and multivariate models of logistic regression. A total of 6421 participants were included in this analysis representing a weighted total of 76,508 women. The prevalence of midwife-led prenatal care was 6.1%. The highest prevalence of midwife-led prenatal care was in British Columbia (9.8%), while the lowest prevalence of midwife-led prenatal care was 0.3% representing the cumulative prevalence in Nova Scotia, Prince Edward Island, Newfoundland and Labrador, New Brunswick, Saskatchewan, and Yukon. Factors showing significant association with midwife-led prenatal care were: Aboriginal status (OR = 2.26, 95% CI: 1.41-3.64), higher education with bachelor and graduate degree attainment having higher ORs when compared to high-school or less (OR = 2.71, 95% CI: 1.71-4.31 and OR = 3.17, 95% CI: 1.81-5.55, respectively), and alcohol use (OR = 1.63, 95% CI: 1.17-2.26). Age, marital status, immigrant status, work during pregnancy, household income, previous pregnancies, perceived health, maternal Body Mass Index (BMI), and smoking during the last 3 months of pregnancy were not significantly associated with midwife care. In general, women who were more educated, have aboriginal status, and/or are alcohol drinkers were more likely to receive care from midwives. Since MES is the most recent resource that includes information about national midwifery utilization, future studies can provide more up

Regional habitat needs of a nationally listed species, Canada Warbler (Cardellina canadensis, in Alberta, Canada

Directory of Open Access Journals (Sweden)

Jeffrey R. Ball

2016-12-01

Full Text Available Understanding factors that affect the distribution and abundance of species is critical to developing effective management plans for conservation. Our goal was to quantify the distribution and abundance of Canada Warbler (Cardellina canadensis, a threatened old-forest associate in Alberta, Canada. The Canada Warbler has declined across its range, including in Alberta where habitat loss and alteration from urban expansion, forestry, and energy development are changing the forest landscape. We used 110,427 point count survey visits from 32,287 unique survey stations to model local-level (150-m radius circular buffers and stand-level (564-m radius circular buffers habitat associations of the Canada Warbler. We found that habitat supporting higher densities of Canada Warblers was locally concentrated yet broadly distributed across Alberta's boreal forest region. Canada Warblers were most commonly associated with older deciduous forest at the local scale, particularly near small, incised streams, and greater amounts of deciduous forest at the stand scale. Predicted density was lower in other forest types and younger age classes measured at the local scale. There was little evidence that local-scale fragmentation (i.e., edges created by linear features influenced Canada Warbler abundance. However, current forestry practices in the province likely will reduce the availability of Canada Warbler habitat over time by cutting old deciduous forest stands. Our results suggest that conservation efforts aimed at Canada Warbler focus on retaining large stands of old deciduous forest, specifically stands adjacent to streams, by increasing the width of deciduous retention buffers along streams during harvest and increasing the size and number of old forest residual patches in harvested stands.

Uranium in Canada

International Nuclear Information System (INIS)

1989-01-01

In 1988 Canada's five uranium producers reported output of concentrate containing a record 12,470 metric tons of uranium (tU), or about one third of total Western world production. Shipments exceeded 13,200 tU, valued at $Cdn 1.1 billion. Most of Canada's uranium output is available for export for peaceful purposes, as domestic requirements represent about 15 percent of production. The six uranium marketers signed new sales contracts for over 11,000 tU, mostly destined for the United States. Annual exports peaked in 1987 at 12,790 tU, falling back to 10,430 tU in 1988. Forward domestic and export contract commitments were more than 70,000 tU and 60,000 tU, respectively, as of early 1989. The uranium industry in Canada was restructured and consolidated by merger and acquisition, including the formation of Cameco. Three uranium projects were also advanced. The Athabasca Basin is the primary target for the discovery of high-grade low-cost uranium deposits. Discovery of new reserves in 1987 and 1988 did not fully replace the record output over the two-year period. The estimate of overall resources as of January 1989 was down by 4 percent from January 1987 to a total (measured, indicated and inferred) of 544,000 tU. Exploration expenditures reached $Cdn 37 million in 1987 and $59 million in 1988, due largely to the test mining programs at the Cigar Lake and Midwest projects in Saskatchewan. Spot market prices fell to all-time lows from 1987 to mid-1989, and there is little sign of relief. Canadian uranium production capability could fall below 12,000 tU before the late 1990s; however, should market conditions warrant output could be increased beyond 15,000 tU. Canada's known uranium resources are more than sufficient to meet the 30-year fuel requirements of those reactors in Canada that are now or are expected to be in service by the late 1990s. There is significant potential for discovering additional uranium resources. Canada's uranium production is equivalent, in

Gamma Ray Sterilization of Starr-Edwards Heart Valve Prostheses

Energy Technology Data Exchange (ETDEWEB)

Gibbons, J. R. P.; Alladine, M. F. [London Chest Hospital, London (United Kingdom)

1967-09-15

Starr-Edwards valves have normally been sterilized by exposure to ethylene oxide or by autoclaving. Patients having a prosthetic valve replacement are known to have a higher incidence of endocarditis in comparison with patients in which no prosthesis has been used. Ethylene oxide will only sterilize the surface of the valve and autoclaving has caused distortion of the polytetrafluorethylene ring. Work has been done on the effect of gamma radiation on the components of these valve prostheses and is given in detail. The bacteriological efficiency, at a total absorbed dose of 2. 5 Mrad, has been established. Thirty valves treated by this method have now been inserted and twelve patients have been examined post-operatively for a period of one to two years. All valves are working normally and there has been no evidence of blood-borne infection or malfunction of the valve. (author)

This region which may represent the eastern flank of the Ross Sea rift system had previously been explored only at reconnaissance level. New total field and upward continued (10 km magnetic anomaly maps are produced and interpreted here to map and discuss the crustal structure of the Edward VII Peninsula. Tworound-shaped, high-amplitude magnetic anomalies are recognised over the Alexandra Mountains block. The anomalies are difficult to interpret since susceptibility data indicate the prevalence of non-magnetic rocks at the surface. A possible interpretation is that the anomalies are due to Cretaceous mafic intrusives distinct from weakly magnetic Byrd Coast Granite of the adjacent Rockefeller Mountains block. Alternatively the anomalies could be related to buried pluton-sized Devonian Ford Granodiorite intruded by dikes. If Cretaceous in age, the former intrusives revealed from the magnetics could also be responsible for contact metamorphism of the adjacent Alexandra Mountains migmatites. Lower amplitude circular anomalies over the Central Plateau and Prestrud Inlet are likely to be caused by unexposed Devonian Ford Granodiorite which crops out in the Ford Ranges. Elongated high-frequency anomalies of the Sulzberger Bay are similar to those recognised over seismically constrained Cenozoic rift-related volcanics of the Ross Sea. A broad magnetic low over the Sulzberger Ice Shelf may be indicative of a fault bounded graben-like basin with sedimentary infill. Overall recognition of magnetic anomaly patterns and trends reveals segmentation of the Edward VII Peninsula and of the adjacent marine areas in distinct crustal blocks. Faults may separate these blocks and they are interpreted to reflect multiple Cretaceous and maybe Cenozoic crustal

South Georgia Island in the Southern Atlantic Ocean has been a key location for the seismic, geomagnetic and oceanic global monitoring networks. However, no permanent geodetic monitoring station had been established there despite the lack of observations from this region within, for example, the International GNSS Service (IGS) network of Global Navigation Satellite System (GNSS) stations. Then, in 2013 the King Edward Point (KEP) Geodetic Observatory was established with a focus on sea level studies and in support of general geoscience applications. Currently, this observatory located roughly half-way along the main island along its northern coastline, consists of two GNSS stations (KEPA and KRSA) with local benchmark networks, allowing the height determinations from the GNSS antennas to be transferred to the KEP tide gauge (GLOSS ID 187) and forming a height reference within the International Terrestrial Reference Frame. In late 2014, three additional GNSS stations (SG01, SG02 and SG03) were established, all located on small islands at the perimeter of the main island. Together the stations provide the best possible geographic distribution to study various geophysical processes in the region. With the GNSS-derived position time series now partly reaching over 4.5 years in length, it has become possible to provide first estimates of vertical land movements for the island and, in particular, KEP with its surrounding area. Together with four precise levelling campaigns of the benchmark network in 2013, 2014 and two in 2017, it has also been possible to investigate the very local character of the vertical motions, ie. the stability of the jetty upon which the tide gauge is mounted. Our measurements show that while South Georgia Island and the area around KEP are rising, the jetty and tide gauge are subsiding. In this study, we will present the preliminary results from the GNSS and levelling measurements and will discuss their impact on the sea level record from the

Petro-Canada 1997 annual report

1998-01-01

Petro-Canada is a dominant player in the petroleum industry in Western Canada as well as on the Grand Banks offshore Newfoundland. This report presents a review of operations, provides detailed statements of the corporation's finances, and a wealth of information of interest to shareholders. The report states that in 1997 Petro-Canada achieved record financial results, following a dramatic turnaround over the past five years. Net earnings for 1997 were $306 million, a $59 million increase over 1996. The company's share price appreciated 34 per cent in 1997 and was one of the most heavily traded stocks in Canada. The company plans to maximize shareholder value by reducing its interests in conventional oil from mature fields in western Canada and by re-investing the proceeds in natural gas development. Petro-Canada is also committed to an expansion that will double production at the Syncrude oil sands plant over the next decade and has tested large in-situ oil sands resources for potential development in northeastern Alberta. On the Atlantic coast too, Petro-Canada is delivering leadership with increasing production from Hibernia, and final approvals in place to proceed with development of the Terra Nova field. International operations are also contributing to the Corporation's profitability by delivering new production from oil fields offshore Norway and from the Sahara Desert in North Africa. tabs., figs

Active Canada 20/20: A physical activity plan for Canada.

2016-03-16

Physical inactivity is a pressing public health concern. In this commentary we argue that Canada's approach to increasing physical activity (PA) has been fragmented and has lacked coordination, funding and a strategic approach. We then describe a potential solution in Active Canada 20/20 (AC 20/20), which provides both a national plan and a commitment to action from non-government and public sectors with a view to engaging corporate Canada and the general public. It outlines a road map for initiating, coordinating and implementing proactive initiatives to address this prominent health risk factor. The identified actions are based on the best available evidence and have been endorsed by the majority of representatives in the relevant sectors. The next crucial steps are to engage all those involved in public health promotion, service provision and advocacy at the municipal, provincial and national levels in order to incorporate AC 20/20 principles into practice and planning and thus increase the PA level of every person in Canada. Further, governments, as well as the private, not-for-profit and philanthropic sectors, should demonstrate leadership and continue their efforts toward providing the substantial and sustained resources needed to recalibrate Canadians' habitual PA patterns; this will ultimately improve the overall health of our citizens.

Canada produces the most hydrogen per capita of any Organization of Economic Cooperation and Development (OECD) country. The majority of this hydrogen is produced by steam methane reforming for industrial use (predominantly oil upgrading and fertilizer production). Canada also has a world leading hydrogen and fuel cell sector. This sector is seeking new methods for making hydrogen for its future energy needs. The paper will discuss Canada's hydrogen and fuel cell sector in the context of its capabilities, its demonstration and commercialization activities and its stature on the world stage. (author)

Some Numbers behind Canada's Decision to Adopt an Orphan Drug Policy: US Orphan Drug Approvals in Canada, 1997-2012.

Science.gov (United States)

Herder, Matthew; Krahn, Timothy Mark

2016-05-01

We examined whether access to US-approved orphan drugs in Canada has changed between 1997 (when Canada chose not to adopt an orphan drug policy) and 2012 (when Canada reversed its policy decision). Specifically, we looked at two dimensions of access to US-approved orphan drugs in Canada: (1) regulatory access; and (2) temporal access. Whereas only 63% of US-approved orphan drugs were granted regulatory approval in 1997, we found that regulatory access to US-approved orphan drugs in Canada increased to 74% between 1997 and 2012. However, temporal access to orphan drugs is slower in Canada: in a head-on comparison of 40 matched drugs, only two were submitted and four were approved first in Canada; moreover, the mean review time in Canada (423 days) was longer than that in the US (mean = 341 days), a statistically significant difference (t[39] = 2.04, p = 0.048). These results raise questions about what motivated Canada's apparent shift in orphan drug policy. Copyright © 2016 Longwoods Publishing.

2012-01-01

A conceptual model of the hydrogeologic framework, geochemistry, and groundwater-flow system of the Edwards-Trinity and related aquifers, which include the Pecos Valley, Igneous, Dockum, Rustler, and Capitan Reef aquifers, was developed as the second phase of a groundwater availability study in the Pecos County region in west Texas. The first phase of the study was to collect and compile groundwater, surface-water, water-quality, geophysical, and geologic data in the area. The third phase of the study involves a numerical groundwater-flow model of the Edwards-Trinity aquifer in order to simulate groundwater conditions based on various groundwater-withdrawal scenarios. Resource managers plan to use the results of the study to establish management strategies for the groundwater system. The hydrogeologic framework is composed of the hydrostratigraphy, structural features, and hydraulic properties of the groundwater system. Well and geophysical logs were interpreted to define the top and base surfaces of the Edwards-Trinity aquifer units. Elevations of the top and base of the Edwards-Trinity aquifer generally decrease from the southwestern part of the study area to the northeast. The thicknesses of the Edwards-Trinity aquifer units were calculated using the interpolated top and base surfaces of the hydrostratigraphic units. Some of the thinnest sections of the aquifer were in the eastern part of the study area and some of the thickest sections were in the Pecos, Monument Draw, and Belding-Coyanosa trough areas. Normal-fault zones, which formed as growth and collapse features as sediments were deposited along the margins of more resistant rocks and as overlying sediments collapsed into the voids created by the dissolution of Permian-age evaporite deposits, were delineated based on the interpretation of hydrostratigraphic cross sections. The lowest aquifer transmissivity values were measured in the eastern part of the study area; the highest transmissivity values were

Full Text Available Haidian Island, which situated at the Northern part of Haikou City of Hainan Province, is an island within a city. Haidian Island is unique in term of it's development which centered around an university, the Hainan University, besides some others important landmarks, such as Haikou city hospital, Baishamen municipal park, Golf Driving Range etc. All commercials, residential, recreational activities etc are planned to serve Hainan University in particular. The study, taking ‘Haidian Island Area Development Control Plan’ as case study, would like to look into the importance of transportation and traffic planning. The study used observation, site investigation and traffic study methods to gather data needed. Firstly the study analyzed the current state of transportation system for Haidian Island in accordance to the Island Development Control plan and Haikou master plan and identified the problems. Then, the study made some recommendations for these problems. The study highlighted the important of non-motorized, cycling and walking as the main transportation system for an education-based island and as supportive to domestic tourism activities found. The transportation planning suggested by the study took ‘green and low-carbon’ approaches considered the role of University as the core activity in the island.

Network constrained wind integration on Vancouver Island

International Nuclear Information System (INIS)

Maddaloni, Jesse D.; Rowe, Andrew M.; Kooten, G. Cornelis van

2008-01-01

The aim of this study is to determine the costs and carbon emissions associated with operating a hydro-dominated electricity generation system (Vancouver Island, Canada) with varying degrees of wind penetration. The focus is to match the wind resource, system demand and abilities of extant generating facilities on a temporal basis, resulting in an operating schedule that minimizes system cost over a given period. This is performed by taking the perspective of a social planner who desires to find the lowest-cost mix of new and existing generation facilities. Unlike other studies, this analysis considers variable efficiency for thermal and hydro-generators, resulting in a fuel cost that varies with respect to generator part load. Since this study and others have shown that wind power may induce a large variance on existing dispatchable generators, forcing more frequent operation at reduced part load, inclusion of increased fuel cost at part load is important when investigating wind integration as it can significantly reduce the economic benefits of utilizing low-cost wind. Results indicate that the introduction of wind power may reduce system operating costs, but this depends heavily on whether the capital cost of the wind farm is considered. For the Vancouver Island mix with its large hydro-component, operating cost was reduced by a maximum of 15% at a wind penetration of 50%, with a negligible reduction in operating cost when the wind farm capital cost was included

Islands and non-islands in native and heritage Korean

Directory of Open Access Journals (Sweden)

Boyoung eKim

2016-02-01

Full Text Available To a large extent, island phenomena are cross-linguistically invariable, but English and Korean present some striking differences in this domain. English has wh-movement and Korean does not, and while both languages show sensitivity to wh-islands, only English has island effects for adjunct clauses. Given this complex set of differences, one might expect Korean/English bilinguals, and especially heritage Korean speakers (i.e. early bilinguals whose L2 became their dominant language during childhood to be different from native speakers, since heritage speakers have had more limited exposure to Korean, may have had incomplete acquisition and/or attrition, and may show significant transfer effects from the L2. Here we examine islands in heritage speakers of Korean in the U.S. Through a series of four formal acceptability experiments comparing these heritage speakers with native speakers residing in Korea, we show that the two groups are remarkably similar. Both show clear evidence for wh-islands and an equally clear lack of adjunct island effects. Given the very different linguistic environment that the heritage speakers have had since early childhood, this result lends support to the idea that island phenomena are largely immune to environmental influences and stem from deeper properties of the processor and/or grammar. Similarly, it casts some doubt on recent proposals that islands are learned from the input.

Class renormalization: islands around islands

International Nuclear Information System (INIS)

Meiss, J.D.

1986-01-01

An orbit of 'class' is one that rotates about a periodic orbit of one lower class with definite frequency. This contrasts to the 'level' of a periodic orbit which is the number of elements in its continued fraction expansion. Level renormalization is conventionally used to study the structure of quasi-periodic orbits. The scaling structure of periodic orbits encircling other periodic orbits in area preserving maps is discussed here. Fixed points corresponding to the accumulation of p/q bifurcations are found and scaling exponents determined. Fixed points for q > 2 correspond to self-similar islands around islands. Frequencies of the island boundary circles at the fixed points are obtained. Importance of this scaling for the motion of particles in stochastic regions is emphasized. (author)

Canada's nuclear export policy

Energy Technology Data Exchange (ETDEWEB)

Morrison, R W; Wonder, E F [Carleton Univ., Ottawa, Ontario (Canada)

1978-01-01

The factors influencing the evolution of Canada's nuclear export policy are examined. Initially, nuclear technology was exported to establish an industry in Canada and to share the technology with other countries. After 1974 an increasingly broad range of political and social factors were taken into account and safeguards became the dominant factor. The indirect impacts of the new policy fall into two groups. One consists of the effects of Canada's leadership in taking a tough stand on safeguards. The second group of effects involve the concern of other countries about access to secure energy supplies and advanced technology.

Seabed characterization for the development of marine renewable energy on the Pacific margin of Canada

Science.gov (United States)

Barrie, J. Vaughn; Conway, Kim W.

2014-07-01

An inventory of Canada's marine renewable energy resources based on numerical modeling of the potential tidal, wave and wind energy has been published that identifies areas with maximum resource potential. However, the inventory does not consider the seabed geological conditions that will control the safe development of seabed installations and cable corridors. The Geological Survey of Canada (Natural Resources Canada) has therefore undertaken an assessment of seafloor geological characteristics and physical environmental parameters that will be encountered during any extensive deployment of marine renewable energy systems for the Pacific offshore of Canada. Here we present an overview of seabed characterization for key sites for each of the three energy types. Narrow passages exiting the Salish Sea near the Canadian boundary with the United States and northwards out of the Strait of Georgia provide very promising sites for tidal generation. Here, elliptical fields of very large subaqueous dunes, from 12 to 28 m in height, present a significant challenge to site development. Along the exposed continental shelf of Vancouver Island focused wave-energy close to shore (40-60 m water depth) offers significant energy potential, but any engineering systems would have to be founded on a seafloor made up of a mobile gravel lag and an extensive boulder pavement. A large wind farm proposed for the Pacific North Coast would be built on an extensive shallow bank that has active sediment transport and a large field of sand ridges that have developed within a macrotidal environment. A significant challenge is providing for a safe seafloor cable corridor of over 100 km that crosses a large subaqueous dune field to connect to the electrical grid on the mainland. These examples show how geoscience has and will provide critical information to project proponents and regulators for the safe development of marine renewable energy.

W. Edwards Deming, quality analysis, and total behavior management.

Science.gov (United States)

Saunders, R R; Saunders, J L

1994-01-01

During the past 10 years, the inclusion of the word "quality" in descriptions of production methods, management approaches, educational systems, service system changes, and so forth, has grown exponentially. It appears that no new approach to any problem is likely to be given much consideration today without overt acknowledgment that some improvement in quality must be the outcome. The origins of the importance of quality are primarily rooted in the awakening recognition of the influence of W. Edwards Deming in the post-World War II restoration of Japanese industry. We provide a brief overview of Deming's approach to modernizing management methods and discuss recent criticisms from the field of organizational behavior management that his approach lacks emphasis on the role of reinforcement. We offer a different analysis of Deming's approach and relate its evolution to the contingencies of reinforcement for the behavior of consulting. We also provide an example of problem solving with Deming's approach in a social service setting familiar to many behavior analysts.

Full Text Available El objetivo del presente artículo consiste en proponer una relectura de la novela El museo de cera, que el escritor chileno Jorge Edwards publicó en 1981, concentrando la atención no sólo en la habitual interpretación crítica que evidencia la lúcida condena satírica del pensamiento reaccionario chileno, sino abordando la trama desde una perspectiva que ilumina la relación entre tiempo individual y colectivo. En paralelo, se examina la representación de la decadencia de una arquitectura sociopolítica, poniendo en relación las imágenes ficcionales de Edwards con las representaciones del declive presentes en la narrativa austrohúngara de comienzos del siglo xx. Se analizan, finalmente, las dinámicas de ósmosis entre los dos espacios geosociales descritos en la ficción evidenciando la permeabilidad de sectores en apariencia opuestos.The purpose of the present article consists of proposing a different interprtetation of the novel El museo de cera, which the Chilean writer Jorge Edwards published in 1981: we will concentrate not only in the habitual critical interpretation that confirms the lucid satirical sentence of the reactionary Chilean thought, but we will approach the plot from a perspective that demonstrates the relation between individual and collective time. At the same time, we analyze the representation of the decadence of a social and political structure, by connecting the fictional images from Edwards with the representations of the decline presented in the Austro-Hungarian narrative of the beginning of the 20th century. Finally, we examine the dynamics of osmosis between the two geosocial contexts described in the fiction demonstrating the permeability of sectors by all appearances opposite.

Incidence of trypanosomes in the Canada goose as revealed by bone marrow culture

1. Techniques are described for the cultural isolation of trypanosomes from avian bone marrow obtained from living birds or at autopsy. A new medium SNB-9 (saline-neopeptone-blood) is described. In addition to being a good medium for growing avian trypanosomes, it is excellent for growing trypanosomes of amphibians and mammals. 2. Evidence is presented demonstrating the superiority of (a) cultures over stained smears for detecting the presence of trypanosomes in the Canada goose, and (b) bone marrow over heart blood of this species as a source of trypanosomes for culture. 3. In April 1952, from cultures of bone marrow collected at autopsy it was demonstrated that trypanosome infection occurred in 33 (40.2%) of 82 Canada geese from the Pea Island National Wildlife Refuge. On February 17, 1953, cultures of bone marrow obtained from living birds revealed presence of trypanosomes in 12 (20.7%) of 58 geese from the same refuge. On February 26, 1953, by employing the latter method, 9 (20.4%) of 44 geese from Blackwater National Wildlife Refuge were shown to harbor the parasites. In another survey ninety-two geese from seven national wildlife refuges subjected to the biopsy technique showed evidence of infection in 13 (14.1 %) birds and indicated that trypanosome infection is widely distributed in this host.

“It’s all about the Money”: Crime in the Caribbean and Its Impact on Canada

Directory of Open Access Journals (Sweden)

Cameron Ross

2014-07-01

Full Text Available For most Canadians, the Caribbean is a place to take an idyllic break from winter. Sandy beaches and warm temperatures lure Canadians to the islands. Interaction with the local population is mostly limited to those who work in hotels and bars. What actually happens in the local communities is generally lost on the average Canadian. Appreciating the large Caribbean diaspora in Toronto and Montreal, the connections are dynamic between those sun-baked Caribbean communities and Canadian society. While those linkages are generally positive, there are disturbing trends in crime in the Caribbean. Herculean efforts are being made by the World Bank, the United Nations, and the regional Caribbean Development Bank to build regional capacity in governance and criminal justice systems. There is, however, a lack of political will by some Caribbean leaders to implement recommendations that would greatly improve citizen security and national institutions. Scholarly and professional studies have made recommendations for the security sector that are achievable, but the political will in many countries has been lagging. The Caribbean drug trade has long held the spotlight, but money laundering is increasingly a concern, especially with evidence of linkages between terrorist groups resident in Central America and Venezuela, which have close proximity to the Caribbean Windward Islands. Post-9/11 financial tools, utilized under the U.S. Patriot Act, have been effective in dealing with rogue governments, corrupt officials, and transnational criminal gangs. However, the use of the Internet for financial transactions and the emergence of digital currencies have made regulatory control challenging. This is significant considering the Canadian tourism, banking, and resource development in the region that have caused steady flows of Canadians, money and expertise to the Caribbean.

Conservation of Peary caribou based on a recalculation of the 1961 aerial survey on the Queen Elizabeth Islands, Arctic Canada

Directory of Open Access Journals (Sweden)

Frank L. Miller

2005-05-01

Full Text Available The estimate of 25 845 Peary caribou (Rangifer tarandus pearyi on the Queen Elizabeth Islands (QEI in the Canadian High Arctic in summer 1961 is the only nearly range-wide 'benchmark' for the past number of caribou. No variances or confidence intervals were calculated for this estimate and no estimates were calculated for Peary caribou on the three major islands of Ellesmere, Devon, and Axel Heiberg. We reexamined the 1961 raw data by grouping the QEI into five island-complexes ('eco-units' and calculating, for each unit, the estimated number of caribou and the standard error, and the 95% confidence interval of the estimate, using a 'bootstrap' technique with 100 000 replications. Our goal was to provide an ecological basis for evaluating subsequent changes in numbers rather than relying on single-island evaluations. Our bootstrap reanalysis produced an estimate of 28 288 ± 2205 SE with a 95% CI of 20 436—37 031 Peary caribou on the QEI in summer 1961. Substantial differences in density were apparent among the five eco-units, with about a 50-fold difference from 0.01 caribou • km-2 in the Eastern eco-unit to 0.5 caribou • km-2 in the Northwestern eco-unit. The 1961 findings, with our subsequent reexamination, are crucial to any evaluation of trends for the number of Peary caribou on the QEI and the relative importance of individual eco-units for these animals. These findings also allow a more accurate evaluation of the magnitude of the subsequent decline of Peary caribou on the QEI during the last four decades and may help predict future potential levels for caribou in each of the five eco-units.

Uranium in Canada: Billion-dollar industry

International Nuclear Information System (INIS)

Whillans, R.T.

1989-01-01

In 1988, Canada maintained its position as the world's leading producer and exporter of uranium; five primary uranium producers reported concentrate output containing 12,400 MT of uranium, or about one-third of Western production. Uranium shipments made by these producers in 1988 exceeded 13,200 MT, worth Canadian $1.1 billion. Because domestic requirements represent only 15% of current Canadian output, most of Canada's uranium production is available for export. Despite continued market uncertainty in 1988, Canada's uranium producers signed new sales contracts for some 14,000 MT, twice the 1987 level. About 90% of this new volume is with the US, now Canada's major uranium customer. The recent implementation of the Canada/US Free Trade agreement brings benefits to both countries; the uranium industries in each can now develop in an orderly, free market. Canada's uranium industry was restructured and consolidated in 1988 through merger and acquisition; three new uranium projects advanced significantly. Canada's new policy on nonresident ownership in the uranium mining sector, designed to encourage both Canadian and foreign investment, should greatly improve efforts to finance the development of recent Canadian uranium discoveries

Canada's nuclear non-proliferation policy

International Nuclear Information System (INIS)

1985-01-01

Canada's non-proliferation and safeguards policy has two objectives: 1) to promote the emergence of a more effective and comprehensive international non-proliferation regime; and 2) to assure the Canadian people and the international community that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the NPT, by promoting reliance upon and improvements in the IAEA safeguards system, by treating nuclear weapon and non-nuclear weapon states alike regarding Canadian nuclear exports, by working for new approaches covering the sensitive phases (e.g. reprocessing) of the nuclear fuel cycle, Canada's policy promotes attainment of the first objective. The latter objective is served through the network of bilateral nuclear agreements that Canada has put into place with its nuclear partners. Those agreements provide assurance that Canada's nuclear exports are used solely for legitimate, peaceful, nuclear energy production purposes. At the same time, Canada, having formulated its non-proliferation and safeguards policy during the period 1945 to 1980, has recognized that it has gone as far as it can on its own in this field and that from this point on any further changes should be made on the basis of international agreement. The Canadian objective in post-INFCE forums such as the Committee on Assurances of Supply is to exert Canada's best efforts to persuade the international community to devise a more effective and comprehensive international non-proliferation regime into which Canada and other suppliers might subsume their national requirements

Foraging Habitat and Chick Diets of Roseate Tern, Sterna dougallii, Breeding on Country Island, Nova Scotia

Directory of Open Access Journals (Sweden)

Jennifer C. Rock

2007-06-01

Full Text Available Breeding seabirds are threatened by human activities that affect nesting and foraging habitat. In Canada, one of the seabirds most at risk of extirpation is the Roseate Tern, Sterna dougallii. Although critical nesting habitat has been identified for the Roseate Tern in Canada, its foraging locations and the diet of its chicks are unknown. Therefore, our goal was to determine the foraging locations and diet of chicks of Roseate Tern breeding on Country Island, Nova Scotia, which is one of Canada's two main breeding colonies. In 2003 and 2004, we radio-tracked the Roseate Tern by plane to locate foraging areas and conducted feeding watches to determine the diet of chicks. Roseate Tern foraged approximately 7 km from the breeding colony over shallow water < 5 m deep. In both years, sand lance, Ammodytes spp., was the most common prey item delivered to chicks, followed by hake, Urophycis spp. Our results are consistent with previous work at colonies in the northeastern United States, suggesting that throughout its range, this species may be restricted in both habitat use and prey selection. The reliance on a specific habitat type and narrow range of prey species makes the Roseate Tern generally susceptible to habitat perturbations and reductions in the availability of prey.

STS-49 Landing at Edwards with First Drag Chute Landing

Science.gov (United States)

1992-01-01

The Space Shuttle Endeavour concludes mission STS-49 at NASA's Ames-Dryden Flight Research Facility (later redesignated Dryden Flight Research Center), Edwards, California, with a 1:57 p.m. (PDT) landing 16 May on Edward's concrete runway 22. The planned 7-day mission, which began with a launch from Kennedy Space Center, Florida, at 4:41 p.m. (PFT), 7 May, was extended two days to allow extra time to rescue the Intelsat VI satellite and complete Space Station assembly techniques originally planned. After a perfect rendezvous in orbit and numerous attempts to grab the satellite, space walking astronauts Pierre Thuot, Rick Hieb and Tom Akers successfully rescued it by hand on the third space walk with the support of mission specialists Kathy Thornton and Bruce Melnick. The three astronauts, on a record space walk, took hold of the satellite and directed it to the shuttle where a booster motor was attached to launch it to its proper orbit. Commander Dan Brandenstein and Pilot Kevin Chilton brought Endeavours's record setting maiden voyage to a perfect landing at Edwards AFB with the first deployment of a drag chute on a shuttle mission. Space Shuttles are the main element of America's Space Transportation System and are used for space research and other space applications. The shuttles are the first vehicles capable of being launched into space and returning to Earth on a routine basis. Space Shuttles are used as orbiting laboratories in which scientists and mission specialists conduct a wide variety of scientific experiments. Crews aboard shuttles place satellites in orbit, rendezvous with satellites to carry out repair missions and return them to space, and retrieve satellites and return them to Earth for refurbishment and reuse. Space Shuttles are true aerospace vehicles. They leave Earth and its atmosphere under rocket power provided by three liquid-propellant main engines with two solid-propellant boosters attached plus an external liquid-fuel tank. After their

Tadesse, Tsegaye; Champagne, Catherine; Wardlow, Brian D.; Hadwen, Trevor A.; Brown, Jesslyn; Demisse, Getachew B.; Bayissa, Yared A.; Davidson, Andrew M.

2017-01-01

Drought is a natural climatic phenomenon that occurs throughout the world and impacts many sectors of society. To help decision-makers reduce the impacts of drought, it is important to improve monitoring tools that provide relevant and timely information in support of drought mitigation decisions. Given that drought is a complex natural hazard that manifests in different forms, monitoring can be improved by integrating various types of information (e.g., remote sensing and climate) that is timely and region specific to identify where and when droughts are occurring. The Vegetation Drought Response Index for Canada (VegDRI-Canada) is a recently developed drought monitoring tool for Canada. VegDRI-Canada extends the initial VegDRI concept developed for the conterminous United States to a broader transnational coverage across North America. VegDRI-Canada models are similar to those developed for the United States, integrating satellite observations of vegetation status, climate data, and biophysical information on land use and land cover, soil characteristics, and other environmental factors. Collectively, these different types of data are integrated into the hybrid VegDRI-Canada to isolate the effects of drought on vegetation. Twenty-three weekly VegDRI-Canada models were built for the growing season (April–September) through the weekly analysis of these data using a regression tree-based data mining approach. A 15-year time series of VegDRI-Canada results (s to 2014) was produced using these models and the output was validated by randomly selecting 20% of the historical data, as well as holdout year (15% unseen data) across the growing season that the Pearson’s correlation ranged from 0.6 to 0.77. A case study was also conducted to evaluate the VegDRI-Canada results over the prairie region of Canada for two drought years and one non-drought year for three weekly periods of the growing season (i.e., early-, mid-, and late season). The comparison of the VegDRI-Canada

Anon

2004-04-15

The 'Building Canada' program modelled after the 'Building America' program, aims at increasing energy efficiency and affordability, primarily for single family homes. The program takes a holistic and whole house view, employing a systems approach and is committed to continuous improvement through testing, evaluation, retesting and novel construction practices. The program's objective is to re-engineer house designs so that builders can take advantage of advanced products and achieve maximum efficiency. Building Canada aims to achieve its objectives through partnership with the housing industry, focusing on increasing energy efficiency while reducing construction time, using and wasting fewer materials, forestalling call backs, and reducing overall costs. The Building Canada procedures encompass marketing, research of builder's operations, re-engineering mechanical systems, framing components and techniques, moisture control and thermal performance, construction, resolution of problems in re-engineered homes, and discussion of results in demonstration homes. The program as a whole is built on the feasibility study of a Building Canada program carried out in Nova Scotia and Ontario. Some of the results of this pilot study summarized in this report indicate that the Building Canada is not suitable for use by small builders. Benefits are most likely to be realized by only by builders constructing more than 100 homes annually.

2008-01-01

The Diomede Islands consisting of the western island Big Diomede (also known as Imaqliq, Nunarbuk or Ratmanov Island), and the eastern island Little Diomede (also known as Krusenstern Island or Inaliq), are two rocky islands located in the middle of the Bering Strait between Russia and Alaska. The islands are separated by an international border and the International Date Line which is approximately 1.5 km from each island; you can look from Alaska into tomorrow in Russia. At the closest land approach between the United States, which controls Little Diomede, and Russia, which controls Big Diomede, they are 3 km apart. Little Diomede Island constitutes the Alaskan City of Diomede, while Big Diomede Island is Russia's easternmost point. The first European to reach the islands was the Russian explorer Semyon Dezhnev in 1648. The text of the 1867 treaty finalizing the sale of Alaska uses the islands to designate the border between the two nations. The image was acquired July 8, 2000, covers an area of 13.5 x 10.8 km, and is located at 65.8 degrees north latitude, 169 degrees west longitude. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.

Paradise Islands? Island States and Environmental Performance

Directory of Open Access Journals (Sweden)

Sverker C. Jagers

2016-03-01

Full Text Available Island states have been shown to outperform continental states on a number of large-scale coordination-related outcomes, such as levels of democracy and institutional quality. The argument developed and tested in this article contends that the same kind of logic may apply to islands’ environmental performance, too. However, the empirical analysis shows mixed results. Among the 105 environmental outcomes that we analyzed, being an island only has a positive impact on 20 of them. For example, island states tend to outcompete continental states with respect to several indicators related to water quality but not in aspects related to biodiversity, protected areas, or environmental regulations. In addition, the causal factors previously suggested to make islands outperform continental states in terms of coordination have weak explanatory power in predicting islands’ environmental performance. We conclude the paper by discussing how these interesting findings can be further explored.

A drag chute slows the space shuttle Columbia as it rolls to a perfect landing concluding NASA's longest mission at that time, STS-58, at the Ames-Dryden Flight Research Facility (later redesignated the Dryden Flight Research Center), Edwards, California, with a 8:06 a.m. (PST) touchdown 1 November 1993 on Edward's concrete runway 22. The planned 14 day mission, which began with a launch from Kennedy Space Center, Florida, at 7:53 a.m. (PDT), October 18, was the second spacelab flight dedicated to life sciences research. Seven Columbia crewmembers performed a series of experiments to gain more knowledge on how the human body adapts to the weightless environment of space. Crewmembers on this flight included: John Blaha, commander; Rick Searfoss, pilot; payload commander Rhea Seddon; mission specialists Bill MacArthur, David Wolf, and Shannon Lucid; and payload specialist Martin Fettman. Space Shuttles are the main element of America's Space Transportation System and are used for space research and other space applications. The shuttles are the first vehicles capable of being launched into space and returning to Earth on a routine basis.

An Integrated Hydrogeologic and Geophysical Investigation to Characterize the Hydrostratigraphy of the Edwards Aquifer in an Area of Northeastern Bexar County, Texas

Science.gov (United States)

Shah, Sachin D.; Smith, Bruce D.; Clark, Allan K.; Payne, Jason

2008-01-01

In August 2007, the U.S. Geological Survey, in cooperation with the San Antonio Water System, did a hydrogeologic and geophysical investigation to characterize the hydrostratigraphy (hydrostratigraphic zones) and also the hydrogeologic features (karst features such as sinkholes and caves) of the Edwards aquifer in a 16-square-kilometer area of northeastern Bexar County, Texas, undergoing urban development. Existing hydrostratigraphic information, enhanced by local-scale geologic mapping in the area, and surface geophysics were used to associate ranges of electrical resistivities obtained from capacitively coupled (CC) resistivity surveys, frequency-domain electromagnetic (FDEM) surveys, time-domain electromagnetic (TDEM) soundings, and two-dimensional direct-current (2D-DC) resistivity surveys with each of seven hydrostratigraphic zones (equivalent to members of the Kainer and Person Formations) of the Edwards aquifer. The principal finding of this investigation is the relation between electrical resistivity and the contacts between the hydrostratigraphic zones of the Edwards aquifer and the underlying Trinity aquifer in the area. In general, the TDEM data indicate a two-layer model in which an electrical conductor underlies an electrical resistor, which is consistent with the Trinity aquifer (conductor) underlying the Edwards aquifer (resistor). TDEM data also show the plane of Bat Cave fault, a well-known fault in the area, to be associated with a local, nearly vertical zone of low resistivity that provides evidence, although not definitive, for Bat Cave fault functioning as a flow barrier, at least locally. In general, the CC resistivity, FDEM survey, and 2D-DC resistivity survey data show a sharp electrical contrast from north to south, changing from high resistivity to low resistivity across Bat Cave fault as well as possible karst features in the study area. Interpreted karst features that show relatively low resistivity within a relatively high

Canada's nuclear non-proliferation policy

1982-05-01

Canada's non-proliferation safeguards policy has two objectives: 1) to promote a more effective and comprehensive international non-proliferation regime; and 2) to ensure that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the Non-Proliferation Treaty, promoting reliance upon and improvements in the IAEA safeguards system, treating nuclear weapon and non-weapon states alike, and working for new approaches covering reprocessing, Canada promotes attainment of the first objective. The second is served through the network of bilateral nuclear agreements that Canada has put into place with its partners. The Canadian objective in post-INFCE forums is to persuade the international community to devise a more effective and comprehensive non-proliferation regime into which Canada and other suppliers may subsume their national requirements

Migrants and Their Experiences of Time: Edward T. Hall Revisited

Directory of Open Access Journals (Sweden)

Elisabeth Schilling

2009-01-01

Full Text Available In this paper we reassess the scientific heritage of Edward T. HALL and his contribution to the area of intercultural communication. The key objectives of our study are to demonstrate the applicability of HALL's theory of culture to empirical research and to establish its compatibility with other methods. Specifically, we propose that Alfred SCHÜTZ's phenomenology of sociality be taken as an extension to HALL. The connection between HALL and SCHÜTZ is made possible by the mutual emphases on the temporal dimension of culture and the temporal aspects of migration. With these foci we analyze six narratives by two groups of migrants: German and Russian. By combining HALL's theory of the cultural time with SCHÜTZ's phenomenological perspective on time and the Other and then applying them to empirical data, we show the terms in which different cultures experience time.

Taxi and limousine industry in Canada

International Nuclear Information System (INIS)

Monteiro, J.; Civettini, S.

2007-01-01

Taxi and limousine service plays an important role in the movement of people within a city. In 2004, the total revenue in this industry in Canada was $1.305 billion, and an estimated 35,339 carriers served the industry. In Canada, economic and safety regulations of taxi supply were imposed in most cities during the 1930s and 1940s and continue to this date. Although the industry is regulated, the competition law also applies. The appropriateness of these regulations continues to be challenged and regulatory reforms in the major cities in Canada have concentrated their efforts on increasing the rate of services, improving the quality of vehicles and enhancing the training of taxi drivers. Indicators for the 1999-2004 period reveal that the taxi and limousine industry in Canada did not perform very well. Revenue increased by only 1.7 per cent per year and margins deteriorated by -1.78 per cent together with the operating ratio. The purpose of this paper was to examine the taxi and limousine industry in Canada. First, the structure of the industry in Canada was examined followed by a review of the economic regulation of the industry. Recent regulatory developments in Canada and in other countries were then reviewed with arguments for or against deregulation. 28 refs., 2 tabs

Petro-Canada's 2001 report in support of Canada's climate change voluntary challenge and registry

2001-01-01

One of the leading oil and gas companies in Canada, Petro-Canada is committed to the Climate Change Voluntary Challenge and Registry (VCR) Program. In this document, the major initiatives undertaken by Petro-Canada with the aim of reducing greenhouse gas emissions were highlighted. The successes in improving energy efficiency in the process of reducing greenhouse gas emissions were reviewed. A major accomplishment in 2000 was the total greenhouse gas emissions resulting from the operations of Petro-Canada that were below the level of 1990, even in the face of a one-third increase in production over the last ten years. As a result, a reduction in excess of 45,000 tonnes of ongoing annual emissions was achieved. The targets that were set are a one per cent reduction every year from 2000 to 2005 through reductions in fuel consumption. The Production Energy Intensity (PEI) of the upstream was improved in 2000 by 11 per cent when compared to 1999 value. Energy efficiency projects have been allocated a total of 4 million dollars in capital funds, and emerging technologies in alternate fuels are being monitored to enable Petro-Canada to reduce the emissions of greenhouse gases. Several education projects are being funded to enhance public awareness of climate change issues. 4 tabs., 7 figs

A preliminary spatial assessment of risk: Marine birds and chronic oil pollution on Canada's Pacific coast.

Fox, C H; O'Hara, P D; Bertazzon, S; Morgan, K; Underwood, F E; Paquet, P C

2016-12-15

Chronic oil pollution poses substantial risks to marine birds and other marine wildlife worldwide. On Canada's Pacific coast, the negative ecological consequences to marine birds and marine ecosystems in general remain poorly understood. Using information relating to oil spill probability of occurrence, areas of overall importance to marine birds, and the at-sea distribution and density of 12 marine bird species and seven bird groups, including multiple Species at Risk, we undertook a spatial assessment of risk. Our results identify two main areas important to marine birds potentially at higher risk of exposure to oil. For individual bird species or species groups, those predicted to have elevated bird densities near the mainland and the northeast coast of Vancouver Island were identified as being at higher potential risk of exposure. Our results, however, should be considered preliminary. As with other anthropogenic stressors, in order to better understand and subsequently mitigate the consequences of chronic oil pollution on marine birds, improved information relating to marine birds and the occurrence of oil spills on Canada's Pacific coast is needed.

Canada's isotope crisis : what next?

International Nuclear Information System (INIS)

Nathwani, J.; Wallace, D.

2010-01-01

Canada urgently requires a rigorous debate on the strategic options for ensuring a robust, reliable, and affordable supply of radioactive isotopes. Should the debate be confined to how Canada can best develop the necessary technologies solely for our own use or should Canada abandon the idea of producing its own isotope supply and any future aspirations to serve the global market? Canada's Isotope Crisis focuses on the central policy question: do we dare to try to shape the future or do we retreat into silence because we are not prepared to make the necessary investments for the future well-being of Canadians? This volume showcases pointed essays and analysis from members of the academy and individuals who have made contributions to the development of medical isotopes and pioneered their use in medical practice. It also includes commentary from those involved in the production, manufacturing, processing, and distribution of isotopes. Canada's Isotope Crisis is a multi-disciplinary effort that addresses the global dimension of isotope supply and combines expert opinions on the present and past with knowledge of the relevant government agencies and the basis for their decisions at critical junctures.

Suicide policy in Canada: lessons from history.

Spiwak, Rae; Elias, Brenda; Bolton, James M; Martens, Patricia J; Sareen, Jitender

2012-07-18

In Canada, suicide has transitioned from being a criminal activity with much associated stigma, to being a public health concern that needs to be managed by governments and clinicians in a culturally sensitive manner. In Canada and worldwide, the social attitudes toward and legal interpretation of suicide have been dynamic. Much has been proposed in the development of suicide policy in Canada, however Canada is unique in that it remains one of the only industrialized countries without a national suicide prevention strategy. The current article provides a critical review of the history of suicide in Canada, as well as an appraisal of Canadian suicide prevention policies and key government and political milestones that have impacted suicide policy. Current activity regarding a national suicide prevention strategy in Canada is discussed, as well as potential options for clinician involvement.

METHODS This descriptive and retrospective study of a case series included all patients diagnosed with ES in a Clinical Genetics Service of a reference hospital in Southern Brazil from 1975 to 2008. The results of the karyotypic analysis, along with clinical data, were collected from medical records. RESULTS: The sample consisted of 50 patients, of which 66% were female. The median age at first evaluation was 14 days. Regarding the karyotypes, full trisomy of chromosome 18 was the main alteration (90%. Mosaicism was observed in 10%. The main craniofacial abnormalities were: microretrognathia (76%, abnormalities of the ear helix/dysplastic ears (70%, prominent occiput (52%, posteriorly rotated (46% and low set ears (44%, and short palpebral fissures/blepharophimosis (46%. Other uncommon - but relevant - abnormalities included: microtia (18%, orofacial clefts (12%, preauricular tags (10%, facial palsy (4%, encephalocele (4%, absence of external auditory canal (2% and asymmetric face (2%. One patient had an initial suspicion of oculo-auriculo-vertebral spectrum (OAVS or Goldenhar syndrome. CONCLUSIONS: Despite the literature description of a characteristic clinical presentation for ES, craniofacial alterations may be variable among these patients. The OAVS findings in this sample are noteworthy. The association of ES with OAVS has been reported once in the literature.

on contemporary theories of nissology and conceptual analytical frameworks for island research. Through a review of selected case-study-based island literature on changing livelihoods coming out of the South Pacific, we wish to illustrate and discuss advantages of finding common grounds for small island studies....... The focus is on two dimensions of island livelihood, migration and natural resource management, both of which are significant contributors in making island livelihoods and shaping Pacific seascapes. We argue that there is still a substantial lack of studies targeting small island dynamics that are empirical...

Critical energy infrastructure protection in Canada

Energy Technology Data Exchange (ETDEWEB)

Gendron, Angela [Canadian Centre for Intelligence and Security Studies, Carleton University (Canada)

2010-12-15

In Canada government acknowledged the need to protect energy assets against attacks. However, so far no strategy has been developed. The aim of this report is to present the characteristics of the energy sector in Canada, the threats, and how the government is responding to those threats. The energy sector in Canada is concentrated and diverse and is under not only terrorism or cyber attacks threats but also environmental threats. This report shows that the Government of Canada is focusing on the protection and assurance of important energy infrastructures but that they are facing several challenges resulting in long delays in the adoption of a formal strategy.

Stepping-stones to the Edge: Artistic Expressions of Islandness in an Ocean of Islands

Directory of Open Access Journals (Sweden)

Laurie Brinklow

2013-05-01

Full Text Available Since the earliest of times, islands have captured the artistic imagination—and, often, for the artist who finds his or her muse in being ‘islanded’, the smaller the island the better. Archipelagos offer an ideal setting for artists who take their inspiration from place: on small islands off islands they can experience an intensity of island living they might not otherwise have on a main island: boundedness and connection, isolation and community. This paper examines expressions of islandness by artists who live on islands off islands that are poles apart—‘archipelagos’ of the Canadian North Atlantic and the Great Southern Ocean. It draws upon interviews with those artists and writers to consider the nature of humans’ attachment and attraction to islands, exploring through the lens of phenomenology what Stratford et al. call the “entanglement between and among islands”.

Modeling the distribution of Norway rats (Rattus norvegicus on offshore islands in the Falkland Islands

Directory of Open Access Journals (Sweden)

Michael A. Tabak

2015-01-01

Full Text Available Non-native rats (Rattus spp. threaten native island species worldwide. Efforts to eradicate them from islands have increased in frequency and become more ambitious in recent years. However, the long-term success of some eradication efforts has been compromised by the ability of rats, particularly Norway rats (Rattus norvegicus which are good swimmers, to recolonize islands following eradications. In the Falkland Islands, an archipelago in the South Atlantic Ocean, the distance of 250 m between islands (once suggested as the minimum separation distance for an effective barrier to recolonization has shown to be insufficient. Norway rats are present on about half of the 503 islands in the Falklands. Bird diversity is lower on islands with rats and two vulnerable passerine species, Troglodytes cobbi (the only endemic Falkland Islands passerine and Cinclodes antarcticus, have greatly reduced abundances and/or are absent on islands with rats. We used logistic regression models to investigate the potential factors that may determine the presence of Norway rats on 158 islands in the Falkland Islands. Our models included island area, distance to the nearest rat-infested island, island location, and the history of island use by humans as driving variables. Models best supported by data included only distance to the nearest potential source of rats and island area, but the relative magnitude of the effect of distance and area on the presence of rats varied depending on whether islands were in the eastern or western sector of the archipelago. The human use of an island was not a significant parameter in any models. A very large fraction (72% of islands within 500 m of the nearest potential rat source had rats, but 97% of islands farther than 1,000 m away from potential rat sources were free of rats.

Many karst regions are undergoing rapid population growth and expansion of urban land accompanied by increases in wastewater generation and changing patterns of nitrate (NO{sub 3}{sup −}) loading to surface and groundwater. We investigate variability and sources of NO{sub 3}{sup −} in a regional karst aquifer system, the Edwards aquifer of central Texas. Samples from streams recharging the aquifer, groundwater wells, and springs were collected during 2008–12 from the Barton Springs and San Antonio segments of the Edwards aquifer and analyzed for nitrogen (N) species concentrations and NO{sub 3}{sup −} stable isotopes (δ{sup 15}N and δ{sup 18}O). These data were augmented by historical data collected from 1937 to 2007. NO{sub 3}{sup −} concentrations and discharge data indicate that short-term variability (days to months) in groundwater NO{sub 3}{sup −} concentrations in the Barton Springs segment is controlled by occurrence of individual storms and multi-annual wet-dry cycles, whereas the lack of short-term variability in groundwater in the San Antonio segment indicates the dominance of transport along regional flow paths. In both segments, longer-term increases (years to decades) in NO{sub 3}{sup −} concentrations cannot be attributed to hydrologic conditions; rather, isotopic ratios and land-use change indicate that septic systems and land application of treated wastewater might be the source of increased loading of NO{sub 3}{sup −}. These results highlight the vulnerability of karst aquifers to NO{sub 3}{sup −} contamination from urban wastewater. An analysis of N-species loading in recharge and discharge for the Barton Springs segment during 2008–10 indicates an overall mass balance in total N, but recharge contains higher concentrations of organic N and lower concentrations of NO{sub 3}{sup −} than does discharge, consistent with nitrification of organic N within the aquifer and consumption of dissolved oxygen. This study demonstrates

Petro-Canada annual report, 1992

International Nuclear Information System (INIS)

1993-01-01

Petro-Canada was formed as Canada's national energy corporation by an act of Parliament in 1975. Operations began in January 1976, and the company was privatized in July 1991. In 1992, Petro-Canada markedly improved its operating performance by sharply cutting operating and overhead costs. Strategy in the company's resource division was refocused to concentrate future investment in western Canada light oil and natural gas and in Grand Banks light oil. Petro-Canada sold a 5% interest in the Syncrude oil sands project for $132 million as part of its plan to rebalance its portfolio. In the products division, Petro-Canada is reducing capacity and eliminating inefficient parts of its marketing network as a response to low demand. Operating earnings improved $252 million to reach $109 million, versus a $143 million loss in 1991. Net earnings were $9 million, compared to a $598 million loss in 1991. Total oil and natural gas liquids production was 80,000 bbl/d and natural gas production was 517 million ft 3 /d. Refined product sales were 43,000 m 3 /d at an average refinery utilization of 72%. Proved oil and natural gas liquids reserves were 417 million bbl and proved natural gas reserves were 2.4 trillion ft 3 . Debt was reduced by almost $700 million during 1992. The year's activities in production and sales of natural gas, synthetic and natural crude oil, gasoline, and oil sands are summarized. A 6-year operating and financial summary is included, along with a financial statement. 11 figs., 17 tabs

Osadetz, K.G.

1997-01-01

The Geological Survey of Canada (GSC) has an ongoing national hydrocarbon resource assessment project which examines, characterizes and quantifies the hydrocarbon resource potential of Canada. In this paper the distribution, characteristics and sizes of conventional and unconventional natural gas resources in Canada are summarized. Four topics were addressed: (1) the origins of conventional and unconventional natural hydrocarbon gases in Canada, (2) the resource assessment techniques used at the GSC, with emphasis on predicting undiscovered reserves, (3) the setting, distribution and size of the conventional natural gas endowment of Canada in a geographic and geological context, and (4) the indications of unconventional natural gas resource endowment in Canada. Conventional in-place natural gas resources for Canada was estimated at 26.8 trillion cubic metres of which 54 per cent comes from the Western Canada Sedimentary Basin. The national inventory of unconventional in-place gas resource is 3,460 trillion cubic metres. At current rates of production, the expected life expectancy for the in-place conventional natural gas resource base was estimated to be about 150 years. 1 tab., 9 figs

In contingency of a nuclear emergency event, requiring application of intervention measures on a federal scale, Canada has of a plan ensuring the compatibility of the plans of different provinces and serving as interface between federal and provincial authorities. Exclusive of a nuclear attack against North America, by nuclear emergency it is understood an accident resulting in radionuclide release. This is called the Plan of federal intervention in case of nuclear emergency. 'Sante Canada' is the federal authority responsible for intervention in case of nuclear emergency and it has the task of preparing and coordinating the actions on a federal scale.Should the plan be set in action and if the emergency has repercussions upon the agricultural sector, the sustaining organism will be 'Agriculture and agroalimentaire Canada' which in case of emergency acts through the channels of the National System of intervention in the agro-alimentary sector (SNIUA). The paper presents the objectives, the principles of organization and operation, the responsibilities and the plans which SNIUA has in its charge to implement in case of emergency

The nuclear industry in Canada

International Nuclear Information System (INIS)

Anderson, D.; Broughton, W.

1992-01-01

The nuclear industry in Canada comprises three identifiable groups: (1) Atomic Energy of Canada Limited (AECL), (2) electrical utilities that use nuclear power plants, (3) private engineering and manufacturing companies. At the end of World War II, AECL was charged with investigating and developing peaceful uses of atomic power. Included in the results is the Canada deuterium uranium (CANDU) reactor, a peculiarly Canadian design. The AECL maintains research capability and operates as the prime nuclear steam supply system supplier. Utilities in three Canadian provinces operate nuclear power plants, New Brunswick, Quebec, and Ontario, with the majority in Ontario. From the beginning of the nuclear program in Canada, private industry has been an important partner to AECL and the utilities, filling roles as manufacturing subcontractors and as component designers. The prime objective of this paper is to illuminate the role of private industry in developing and maintaining a competitive world-class nuclear industry

Shuttle Discovery Landing at Edwards

1989-01-01

The STS-29 Space Shuttle Discovery mission lands at NASA's then Ames-Dryden Flight Research Facility, Edwards AFB, California, early Saturday morning, 18 March 1989. Touchdown was at 6:35:49 a.m. PST and wheel stop was at 6:36:40 a.m. on runway 22. Controllers chose the concrete runway for the landing in order to make tests of braking and nosewheel steering. The STS-29 mission was very successful, completing the launch of a Tracking and Data Relay communications satellite, as well as a range of scientific experiments. Discovery's five-man crew was led by Commander Michael L. Coats, and included pilot John E. Blaha and mission specialists James P. Bagian, Robert C. Springer, and James F. Buchli. Space Shuttles are the main element of America's Space Transportation System and are used for space research and other space applications. The shuttles are the first vehicles capable of being launched into space and returning to Earth on a routine basis. Space Shuttles are used as orbiting laboratories in which scientists and mission specialists conduct a wide variety of scientific experiments. Crews aboard shuttles place satellites in orbit, rendezvous with satellites to carry out repair missions and return them to space, and retrieve satellites and return them to Earth for refurbishment and reuse. Space Shuttles are true aerospace vehicles. They leave Earth and its atmosphere under rocket power provided by three liquid-propellant main engines with two solid-propellant boosters attached plus an external liquid-fuel tank. After their orbital missions, they streak back through the atmosphere and land like airplanes. The returning shuttles, however, land like gliders, without power and on runways. Other rockets can place heavy payloads into orbit, but, they can only be used once. Space Shuttles are designed to be continually reused. When Space Shuttles are used to transport complete scientific laboratories into space, the laboratories remain inside the payload bay throughout

The burden of cardiovascular disease (CVD) in Canada and other developed countries is growing, in part because of the aging of the population and the alarming rise of obesity. Studying Canada's contribution to the global body of CVD research output will shed light on the effectiveness of investments in Canadian CVD research and inform if Canada has been responding to its CVD burden. Search was conducted using the Web-of-Science database for publications during 1981 through 2010 on major areas and specific interventions in CVD. Search was also conducted using Canadian and US online databases for patents issued between 1981 and 2010. Search data were used to estimate the proportions of the world's pool of research publications and of patents conducted by researchers based in Canada. The results indicate that Canada contributed 6% of global research in CVD during 1981 through 2010. Further, Canada's contribution shows a strong upward trend during the period. Based on patent data, Canada's contribution level was similar (5%-7%). Canada's contribution to the global pool of CVD research is on par with France and close to the UK, Japan, and Germany. Canada's contribution in global CVD research is higher than its average contribution in all fields of research (6% vs 3%). As the burden of chronic diseases including CVD rises with Canada's aging population, the increase in Canadian research into CVD is encouraging. Copyright © 2013 Canadian Cardiovascular Society.

The sex pheromone of the scarab beetle, Phyllophaga anxia, is a blend of the methyl esters of two amino acids, L-valine and L-isoleucine. A field trapping study was conducted, deploying different blends of the two compounds at 59 locations in the United States and Canada. More than 57,000 males of 61 Phyllophaga species (Coleoptera: Scarabaeidae: Melolonthinae) were captured and identified. Three major findings included: (1) widespread use of the two compounds [of the 147 Phyllophaga (sensu stricto) species found in the United States and Canada, males of nearly 40% were captured]; (2) in most species intraspecific male response to the pheromone blends was stable between years and over geography; and (3) an unusual pheromone polymorphism was described from P. anxia. Populations at some locations were captured with L-valine methyl ester alone, whereas populations at other locations were captured with L-isoleucine methyl ester alone. At additional locations, the L-valine methyl ester-responding populations and the L-isoleucine methyl ester-responding populations were both present, producing a bimodal capture curve. In southeastern Massachusetts and in Rhode Island, in the United States, P. anxia males were captured with blends of L-valine methyl ester and L-isoleucine methyl ester. PMID:19537965

Summary of spill events in Canada : 1984 - 1995

International Nuclear Information System (INIS)

1998-11-01

The trends in hazardous material spill events in Canada were summarized for the 12-year period 1984 to 1995. Findings were presented on the number and quantity of spills. The report includes data on the seven major sectors that incur spills. These include the chemical, government, metallurgy, mining, petroleum, pulp and paper and service industry sectors. The causes and reasons for these spills, and any environmental impacts, are described. Case histories of four significant environmental incidents were reviewed in detail. These include a warehouse fire at Canning, Nova Scotia in 1986, a tire fire at Hagersville, Ontario in 1990, a train derailment in Hervey Junction, Quebec in 1995, and the Nestucca oil spill in Gray's Harbour near Vancouver Island, British Columbia in 1988. Equipment failure and human error were pinpointed as the most common cause of spills, followed by corrosion, material failure and storm or flood. Fifty-eight per cent of all reported spills involve oil and petroleum products. Wastes and effluents account for 89 per cent of the total quantity of reported spills. These findings make the report particularly well suited for use as a tool in developing appropriate spill prevention strategies. 15 refs., 26 tabs., 42 figs

The Interfaith Program for Public Awareness of Nuclear Issues (IPPANI) is a committee of representatives of religious groups in Toronto, a group of people concerned about the moral and ethical implications of the operation of Canada's nuclear industry and of its exports to other countries. The faith groups represented are the Anglican Diocese of Toronto, the Baha'i Community of Canada, the Jewish Community of Toronto, the Roman Catholic Archdiocese of Toronto and the United Church of Canada Toronto Conference. Wishing to encourage the Canadian government to enquire into this broad question, the faith groups established IPPANI and assigned to it the task of enhancing their knowledge of the nuclear industry. IPPANI was to develop an effective set of questions to be placed before governments and to promote public discussion so that governments might become more responsive to these issues

Simulation of flow in the Edwards Aquifer, San Antonio region, Texas, and refinement of storage and flow concepts

Science.gov (United States)

Maclay, Robert W.; Land, Larry F.

1988-01-01

The Edwards aquifer is a complexly faulted, carbonate aquifer lying within the Balcones fault zone of south-central Texas. The aquifer consists of thin- to massive-bedded limestone and dolomite, most of which is in the form of mudstones and wackestones. Well-developed secondary porosity has formed in association with former erosional surfaces within the carbonate rocks, within dolomitized-burrowed tidal and evaporitic deposits, and along inclined fractures to produce an aquifer with transmissivities greater than 100 ft2/s. The aquifer is recharged mainly by streamflow losses in the outcrop area of the Edwards aquifer and is discharged by major springs located at considerable distances, as much as 150 mi, from the areas of recharge and by wells. Ground-water flow within the Edwards aquifer of the San Antonio region was simulated to investigate concepts relating to the storage and flow characteristics. The concepts of major interest were the effects of barrier faults on flow direction, water levels, springflow, and storage within the aquifer. A general-purpose, finite-difference model, modified to provide the capability of representing barrier faults, was used to simulate ground-water flow and storage in the aquifer. The approach in model development was to conduct a series of simulations beginning with a simple representation of the aquifer framework and then proceeding to subsequent representations of increasing complexity. The simulations investigated the effects of complex geologic structures and of significant changes in transmissivity, anisotropy, and storage coefficient. Initial values of transmissivity, anisotropy, and storage coefficient were estimated based on concepts developed in previous studies. Results of the simulations confirmed the original estimates of transmissivity values (greater than 100 square feet/s) in the confined zone of the aquifer between San Antonio and Comal Springs. A storage coefficient of 0.05 in the unconfined zone of the aquifer

Differentiating Canada: The Future of the Canada-US Relationship

Directory of Open Access Journals (Sweden)

Wendy Dobson

2010-11-01

Full Text Available Turbulence will mark the world economy in the coming decade as Canada’s traditional trading partners in North America and Europe struggle with slow growth and rising structural unemployment and move, as they must, to restore the health of their public finances. Settling for the status quo is not a compelling option as the US border thickens and Canada stays on the sidelines in two areas vital to its long-term interest: climate change policy and trade liberalization. In this context, the Policy Brief evaluates the strategic options for Canada’s long-standing economic relationship with the United States. The authors propose a two-part proactive strategy. The first part is for Canada to differentiate its economy by building on its macroeconomic, financial and energy strengths relative to the United States and by shaping a best-practice North American climate change policy. The second part of the strategy is to deepen NAFTA by participating in the Trans-Pacific Partnership (TPP, a comprehensive, highquality FTA that has strategic attention of the US administration. Any country can join by accepting the agreement’s provisions. The TPP offers at least two strategic opportunities: a comprehensive negotiation in which Canada, the United States and Mexico could upgrade NAFTA and a way to diversify and deepen trade and investment liberalization with major economies in the Asia-Pacific region.

The aim of this study was to investigate the mid-term haemodynamic and clinical results after aortic valve replacement (AVR) using the Sorin Freedom Solo (SFS) stentless bioprosthesis, compared with the standard Carpentier Edwards Perimount (CEP) stented bioprosthesis. In this retrospective cohort study of prospectively collected data, 116 patients were included in the SFS group (53 males; median age 74 years, range 56-85 years), and 122 patients in the CEP group (85 males; median age 73 years, range 43-88 years) between July 2007 and January 2013. Echocardiography was performed at 6 weeks after surgery in our centre, and the most recent echocardiography (in our centre or in referring cardiology departments) was requested. Between September 2013 and April 2014, all patients were called by the same researcher to gain clinical follow-up data. Mid-term mortality was 16.4% in the SFS group (19 patients) and 21.3% in the CEP group (26 patients); (P = 0.3). The mean transvalvular gradient was 7.4 ± 3.1 mmHg in the SFS group, and 11.6 ± 3.2 mmHg in the CEP group at 6 weeks postoperatively (P Solo stentless bioprosthesis is as safe as the Carpentier Edwards bioprosthesis, and provides better short- and mid-term haemodynamic performance than the Carpentier Edwards bioprosthesis. © The Author 2015.

2009-01-01

A Carpentier-Edwards pericardial (CEP) bioprosthesis was explanted from an 81-year-old woman due to nonstructural dysfunction 9 years after mitral valve replacement. The nonstructural dysfunction produced severe regurgitation in the mitral position. During the surgery, excessive pannus overgrowth was seen on the left ventricular side of the CEP bioprosthesis. Pannus overgrowth was prominent on one leaflet. That leaflet was stiff and shortened due to the excessive overgrowth of pannus. In this patient, the distortion of one leaflet was the main reason for transvalvular leakage of the CEP bioprosthesis in the mitral position. A new CEP bioprosthesis was implanted in the mitral position. Pathological analysis revealed fibrotic pannus with a small amount of cellular material over the leaflets of the resected CEP valve. This change was marked on the distorted leaflet.

Sustainable coastal management is playing an important role in coastal resources conservation, particularly on small islands. Karimata archipelago has unique characteristics and great potential to be developed as a tourism object, one of which is Karimata Island as the largest island and also reserve area. The concept of ecotourism focuses on the ecology conservation, economic benefits, and social life. Ecotourism aims to build sustainable tourism that provides economically viable and social benefits to the community. This study aims to develop coastal management strategy based on ecotourism at Karimata Island. Spatial approaching through coastal type was done. Qualitative descriptive analysis and SWOT are used to develop sustainable management strategies for the coast of Karimata Island, where the opportunities and challenges to the development of coastal ecotourism Karimata Island also included. If this potential is optimally utilized, it can be relied as an economic opportunity for local communities. Structurally shaped coast, marine depositional coast and coast build by organism are several of coastal types found at Karimata Island. Coastal ecosystems inhabited Karimata Island are mangroves, coral reefs, and macro-algae. Karimata Island have not been optimally utilized for tourist destinations. The biggest obstacle encountered is the accessibility from Kalimantan or other island at Karimata islands. Several problems related to the utilization of coastal resources were found such as mangrove and coral reef damage, also regulation that less supportive. The results of this study are expected to provide an overview of solutions for the development of coastal tourism potentials in Karimata Island.

Pain medicine--a new credential in Canada.

Morley-Forster, Patricia; Karpinski, Jolanta

2015-06-01

In 2010, Pain Medicine was formally recognized as a subspecialty in Canada by the Royal College of Physicians and Surgeons of Canada, a national organization with oversight of the medical education of specialists in Canada. The first trainees began their training at the Western University, London, Canada in July, 2014. This article traces the process of Pain Medicine's development as a discipline in Canada and outlines its multiple entry routes, 2-year curriculum, and assessment procedures. The application for specialty status was initiated in 2007 with the understanding that while Anesthesiology would be the parent specialty, the curriculum would train clinicians in a multidisciplinary setting. To receive recognition as a Royal College subspecialty, Pain Medicine had to successfully pass through three phases, each stage requiring formal approval by the Committee on Specialties. The multiple entry routes to this 2-year subspecialty program are described in this article as are the objectives of training, the curriculum, assessment of competency and the practice-eligibility route to certification. The process of accreditation of new training programs across Canada is also discussed. The new Pain Medicine training program in Canada will train experts in the prevention, diagnosis, treatment and rehabilitation of the spectrum of acute pain, cancer pain and non-cancer pain problems. These physicians will become leaders in education, research, advocacy and administration of this emerging field. Wiley Periodicals, Inc.

Canada puts emphasis on SMR

Thanks to hydroelectricity and 16% share of nuclear power, Canada is among the few countries to respect GIEC's 2050 climate objectives: producing 80% of electricity without emitting CO 2 . In the context of a growing power demand, Canada has integrated nuclear energy in its energy scenarios. Small Modular Reactors (SMR) are considered as an efficient means to replace diesel generators used in small isolated communities. Several North America start-ups such as Terrestrial Energy that develops molten salt reactors, have moved to Canada. The British firm Moltex has chosen Canadian Nuclear Safety Authority (CCSN for the certification of its 4. generation reactor. In Ontario, Canada's most populated province, nuclear energy produces 60% of its electricity consumption and has allowed the progressive shutdown of all coal-fed power plants of the province. Between 2000 and 2013 nuclear power increased by 20% whereas the coal share in power production dropped by 27%. The 2014 Toronto Public Health report highlights that since 2004 premature mortality has dropped by 23% and the hospitalization due to air pollution by 41%. (A.C.)

The Edwards-Trinity aquifer system underlies about 42,000 square miles of west-central Texas. Nearly flat-lying, mostly Comanche (Lower Cretaceous) strata of the aquifer system thin northwestward atop massive pre-Cretaceous rocks that are comparatively impermeable and structurally complex. From predominately terrigenous clastic sediments in the east and fluvialdeltaic (terrestrial) deposits in the west, the rocks of early Trinitian age grade upward into supratidal evaporitic and dolomitic strata, intertidal limestone and dolostone, and shallow-marine, openshelf, and reefal strata of late Trinitian, Fredericksburgian, and Washitan age. A thick, downfaulted remnant of mostly open-marine strata of Eaglefordian through Navarroan age composes a small, southeastern part of the aquifer system.

Glaciotectonic deformation and reinterpretation of the Worth Point stratigraphic sequence: Banks Island, NT, Canada

Science.gov (United States)

Vaughan, Jessica M.; England, John H.; Evans, David J. A.

2014-05-01

Hill-hole pairs, comprising an ice-pushed hill and associated source depression, cluster in a belt along the west coast of Banks Island, NT. Ongoing coastal erosion at Worth Point, southwest Banks Island, has exposed a section (6 km long and ˜30 m high) through an ice-pushed hill that was transported ˜ 2 km from a corresponding source depression to the southeast. The exposed stratigraphic sequence is polydeformed and comprises folded and faulted rafts of Early Cretaceous and Late Tertiary bedrock, a prominent organic raft, Quaternary glacial sediments, and buried glacial ice. Three distinct structural domains can be identified within the stratigraphic sequence that represent proximal to distal deformation in an ice-marginal setting. Complex thrust sequences, interfering fold-sets, brecciated bedrock and widespread shear structures superimposed on this ice-marginally deformed sequence record subsequent deformation in a subglacial shear zone. Analysis of cross-cutting relationships within the stratigraphic sequence combined with OSL dating indicate that the Worth Point hill-hole pair was deformed during two separate glaciotectonic events. Firstly, ice sheet advance constructed the hill-hole pair and glaciotectonized the strata ice-marginally, producing a proximal to distal deformation sequence. A glacioisostatically forced marine transgression resulted in extensive reworking of the strata and the deposition of a glaciomarine diamict. A readvance during this initial stage redeformed the strata in a subglacial shear zone, overprinting complex deformation structures and depositing a glaciotectonite ˜20 m thick. Outwash channels that incise the subglacially deformed strata record a deglacial marine regression, whereas aggradation of glaciofluvial sand and gravel infilling the channels record a subsequent marine transgression. Secondly, a later, largely non-erosive ice margin overrode Worth Point, deforming only the most surficial units in the section and depositing a

Numerical simulations of a single magnetic island evolution are presented in the regime where the island width is smaller than an ion Larmor radius. It is shown that the island rotation is controlled by particle diffusion due to collisions or a background of microturbulence. As expected from the theory of a stationary island, there exist cases where linearly stable magnetic perturbation are nonlinearly self-sustained. This situation corresponds to large poloidal beta and temperature gradient. The drive is due to diamagnetic frequency effects. However, this situation is not generic, and islands can also decay. It is found that a magnetic island is self-sustained for a negative off-diagonal diffusion coefficient. This case occurs in a tokamak if the inward particle pinch is due to the temperature gradient.

2016-03-01

Health Canada, in collaboration with Statistics Canada, and other external experts, conducted the Community Noise and Health Study to better understand the impacts of wind turbine noise (WTN) on health and well-being. A cross-sectional epidemiological study was carried out between May and September 2013 in southwestern Ontario and Prince Edward Island on 1238 randomly selected participants (606 males, 632 females) aged 18-79 years, living between 0.25 and 11.22 km from operational wind turbines. Calculated outdoor WTN levels at the dwelling reached 46 dBA. Response rate was 78.9% and did not significantly differ across sample strata. Self-reported health effects (e.g., migraines, tinnitus, dizziness, etc.), sleep disturbance, sleep disorders, quality of life, and perceived stress were not related to WTN levels. Visual and auditory perception of wind turbines as reported by respondents increased significantly with increasing WTN levels as did high annoyance toward several wind turbine features, including the following: noise, blinking lights, shadow flicker, visual impacts, and vibrations. Concern for physical safety and closing bedroom windows to reduce WTN during sleep also increased with increasing WTN levels. Other sample characteristics are discussed in relation to WTN levels. Beyond annoyance, results do not support an association between exposure to WTN up to 46 dBA and the evaluated health-related endpoints.

Full Text Available The Blasket Islands are located off the south-west coast of Ireland. No longer inhabited, the Great Blasket Island and its distinctive culture have been documented by a variety of writers and are celebrated today in an interpretative centre on the mainland and in performances by Siamsa Tíre, The National Folk Theatre of Ireland. “Siamsa” developed from local initiatives in North Kerry during the early 1960s and is located today in Tralee, Co. Kerry. It aims to present Irish folklore and folk culture through the medium of theatre involving music, song, dance and mime but invariably no dialogue. In this paper, I focus on the production Oiléan, based loosely on the stories of the Blasket Islanders, which was initially devised as part of the fiftieth anniversary commemoration of the departure of the last inhabitants of the islands in 2003.

Heron Island is located at the sourthern end of Australia's 2,050 km-long Great Barrier Reef. Surrounded by coral reef and home to over 1000 species of fish, scuba divers and scientists alike are drawn to the island's resort and research station. The true-color image above was taken by Space Imaging's Ikonos satellite with a resolution of 4 meters per pixel-high enough to see individual boats tied up at the small marina. The narrow channel leading from the marina to the ocean was blasted and dredged decades ago, before the island became a national park. Since then the Australian government has implemented conservation measures, such as limiting the number of tourists and removing or recycling, instead of incinerating, all trash. One of the applications of remote sensing data from Ikonos is environmental monitoring, including studies of coral reef health. For more information about the island, read Heron Island.

Grace, Sherry L.; Bennett, Stephanie; Ardern, Chris I.; Clark, Alexander

2015-01-01

Cardiovascular disease is among the leading causes of mortality and morbidity in Canada. Cardiac rehabilitation (CR) has a long robust history here, and there are established clinical practice guidelines. While the effectiveness of CR in the Canadian context is clear, only 34% of eligible patients participate, and strategies to increase access for under-represented groups (e.g., women, ethnic minority groups) are not yet universally applied. Identified CR barriers include lack of referral and physician recommendation, travel and distance, and low perceived need. Indeed there is now a national policy position recommending systematic inpatient referral to CR in Canada. Recent development of 30 CR Quality Indicators and the burgeoning national CR registry will enable further measurement and improvement of the quality of CR care in Canada. Finally, the Canadian Association of CR is one of the founding members of the International Council of Cardiovascular Prevention and Rehabilitation, to promote CR globally. PMID:24607018

It finds that while Canada has made satisfactory progress since 1985, there are still significant challenges, and the report makes specific recommendations for more use of economic instruments and use of the polluter and user pays principles, rationalising water governance, strengthening nature protection, reducing energy intensity, implementing climate change policies, reviewing environmentally related taxes, and implementing marine and aid commitments. Coal provides about 20% of Canada's electric power. Most direct subsidisation of the fossil fuel supply industries (upstream oil, gas and coal) has been reduced. The report recommends subsidies to the mining industry for exploration should also be phased out. Recent measurements indicate emissions of mercury are increasing, mainly due to long-range transboundary air pollution from coal-burning plants. 42 figs., 24 tabs.

Emergy Evaluation of Dwelling Operation in Five Housing Units of Montreal Island, Canada

Directory of Open Access Journals (Sweden)

Ricardo Enrique Vega-Azamar

2017-04-01

Full Text Available Sustainability of cities and the environmental implications of high resource utilization by the domestic sector are growing concerns related to urban regions. Well-informed urban planning decision-making is an essential tool to help in the task and, for that, an important point to consider is the influence of parameters like residential density and housing typology on the intensity of resource utilization. Emergy synthesis, a life-cycle energy analysis methodological approach that considers the interaction of natural and human-made flows, was used to evaluate the environmental support for dwelling operational stage in five typical present-day housing units on the island of Montreal. As expected, resource utilization, measured as total emergy used, was positively correlated to housing unit size both with respect to number of occupants and dwelling size. Results suggest that variables affecting notably the intensity of resource utilization are per household income and per dweller habitable space and, while a higher income increased per capita emergy in all cases, increasing space availability per resident did not result in a decrease of empower density after 50 m2/person. Future work should consider lower and higher densities and analyses at the scale of blocks, neighborhoods and urban planning zones.

Formation and adjustment of typhoon-impacted reef islands interpreted from remote imagery: Nadikdik Atoll, Marshall Islands

Science.gov (United States)

Ford, Murray R.; Kench, Paul S.

2014-06-01

In 1905, a devastating typhoon hit Nadikdik Atoll (5°54‧ N and 172°09‧ E) in the southern Marshall Islands. Evidence suggests that large sections of reef islands on Nadikdik were overwashed and destroyed. Comparison of aerial photographs taken in 1945 and modern satellite imagery provides a unique record of the geomorphic adjustment of islands after the typhoon. Between 1945 and 2010 the vegetated area of islands on Nadikdik grew from 0.74 to 0.90 km2. Observed changes to Nadikdik reef islands manifested through a range of styles and were largely accretionary. Of note, the formation of a new island was tracked from an embryonic deposit to a fully vegetated and stable island over a 61 year period. Similarly, a number of previously discrete islands have agglomerated and formed a single larger island. These changes were rapid and indicate that reef island formation can occur quickly. Evidence suggests that despite the typhoon occurring over a century ago the geomorphic adjustment of islands is still on-going.

Buszka, Paul M.

1987-01-01

Water-chemistry data from the Edwards aquifer for 1976-85, consisting of nearly 1,500 chemical analyses from 280 wells and 3 springs, were used to statistically evaluate relations among ground-water chemistry, hydrogeology, and land use. Five land uses associated with sampled wells were classified on the basis of published information and field surveys. Four major subareas of the aquifer were defined to reflect the relative susceptibility of ground water to contamination originating from human activities using hydrogeologic and tritium data.

At the age of 46, Dr Edward Macgowan, by now a well-established physician, joined the ranks of the London Society for Promoting Christianity among the Jews with the aim of establishing the first modern hospital in Palestine. For the first six months of 1842, Macgowan established his work among the Jerusalem population on a regular basis and managed to establish a close relationship with the Jewish community and some of its leaders in Jerusalem. On 12 December 1844, the Jews' Hospital was opened in Jerusalem and became a source of great pride for the missionaries. Edward Macgowan died in Jerusalem after 18 years of service and was buried in the Protestant cemetery in his beloved city.

Petro-Canada annual report, 1991

International Nuclear Information System (INIS)

1992-03-01

Petro-Canada is Canada's national energy corporation, formed by an Act of Parliament in 1975. Operations began in January 1976. In 1991, Petro-Canada became a public company, issuing 19.5% of its common shares for net proceeds of $523 million. Heavy losses in the first half of the year were driven by price volatility following the Persian Gulf war. Cash flow return on capital employed was 7.2%, and a net loss of $598 million was posted. The Klua gas field was brought on stream only 30 months after discovery, an important gas discovery was made in British Columbia, and production and sales of natural gas increased. This annual report presents a corporate profile, a statement of corporate responsibility, and the year's activities in production and sales of natural gas, synthetic and natural crude oil and gasoline. Details are also provided of Petro-Canada's financial and operational restructuring in view of the declining revenues being obtained. A financial review from 1986 to the present is included, along with a glossary of financial terms, a financial statement, and a 5-year summary. Reserves information comparing the current to the previous year is given. 11 figs., 12 tabs

Canada report on bioenergy 2008

Bradley, D.

2008-06-01

Canada is a nation rich in fossil fuel resources. Canada has a large, well-developed forest sector and is one of the world's largest exporters of wood products. Although national bioenergy policies exist, provincial policies regarding forest resources are necessary because 77 per cent of Canada's forests are under provincial jurisdiction. This report presented an update on Canada's bioenergy policy and resources. The report discussed biomass resources such as woody biomass; agricultural residues; and municipal waste. The use of biomass was presented with particular reference to heat and power; biofuels production; pyrolysis oil; wood pellets; and trends in biomass production and consumption. Current biomass users and biomass prices were also examined. Last, the report addressed imports and exports of ethanol, biodiesel, pyrolysis oil, and wood pellets as well as barriers and opportunities to trade. A list of Canadian bioenergy initiatives and programs was also provided. It was concluded that the greatest opportunities for trade are to succeed in research on super-densified pellets; raise ocean shipping capacity to bring down rates; and to establish and entire biomass industry in Newfoundland Labrador. 20 tabs., 8 figs., 1 appendix

Canada's commitment to nuclear technology

Stewart, Murray J.

1998-01-01

This paper gives a broad update on all facets of the Canadian nuclear industry and demonstrates Canada's continuing commitment to nuclear technology. Canada has developed a global leadership position in nuclear technology for power generation, uranium production and isotope supply. This commitment is being further enhanced by successes in international markets with Candu technology, new uranium mine developments in our province of Saskatchewan, and expanding isotope capabilities including the construction of two new production reactors. Korea's economy is benefiting through collaboration with Canada's leading nuclear companies, both in Korea and Canada. These collaborations have the potential to expand considerably with the implementation of the Kyoto Framework Convention on Climate Change and the anticipated increased demand for new nuclear power generation installations in all major global markets. Much has been publicized about the situation surrounding Ontario Hydro Nuclear and its nuclear recovery program. This paper gives the background and highlights the actions within Ontario and Ontario Hydro designed to ensure the long term recovery of all twenty nuclear units in Ontario. The presentation at the conference will bring the audience completely up-to-date on recent events. (author)

Canada has a great national asset in its ability to generate electricity economically from its abundant hydro, coal, and uranium resources. Its nuclear industry has an excellent product. Despite lack of orders for now, the CANDU will be a competitive force when the reactor market recovers. Canada has a proven record of reliability for electricity trade with the United States. There appear to be some opportunities for plants in Canada dedicated to the export of electric power. The federal government is prepared to work closely with the provinces to develop projects which will be attractive to customers in the United States

Grau Galofre, Anna; Jellinek, A. Mark; Osinski, Gordon R.; Zanetti, Michael; Kukko, Antero

Subglacial meltwater channels (N-channels) are attributed to erosion by meltwater in subglacial conduits. They exert a major control on meltwater accumulation at the base of ice sheets, serving as drainage pathways and modifying ice flow rates. The study of exposed relict subglacial channels offers a unique opportunity to characterize the geomorphologic fingerprint of subglacial erosion as well as study the structure and characteristics of ice sheet drainage systems. In this study we present detailed field and remote sensing observations of exposed subglacial meltwater channels in excellent preservation state on Devon Island (Canadian Arctic Archipelago). We characterize channel cross section, longitudinal profiles, and network morphologies and establish the spatial extent and distinctive characteristics of subglacial drainage systems. We use field-based GPS measurements of subglacial channel longitudinal profiles, along with stereo imagery-derived digital surface models (DSMs), and novel kinematic portable lidar data to establish a detailed characterization of subglacial channels in our field study area, including their distinction from rivers and other meltwater drainage systems. Subglacial channels typically cluster in groups of ˜ 10 channels and are oriented perpendicular to active or former ice margins. Although their overall direction generally follows topographic gradients, channels can be oblique to topographic gradients and have undulating longitudinal profiles. We also observe that the width of first-order tributaries is 1 to 2 orders of magnitude larger than in Devon Island river systems and approximately constant. Furthermore, our findings are consistent with theoretical expectations drawn from analyses of flow driven by gradients in effective water pressure related to variations in ice thickness. Our field and remote sensing observations represent the first high-resolution study of the subglacial geomorphology of the high Arctic, and provide

Simeonof Island is located south of the Alaska Peninsula in the hyperoceanic sector of the middle boreal subzone. We examined the bryoflora of Simeonof Island to determine species composition in an area where no previous collections had been reported. This field study was conducted in sites selected to represent the spectrum of environmental variation within Simeonof Island. Data were analyzed using published reports to compare bryophyte distribution patterns at three levels, the Northern Hemisphere, North America, and Alaska. A total of 271 bryophytes were identified: 202 mosses and 69 liverworts. The annotated list of species for Simeonof Island expands the known range for many species and fills distribution gaps within Hulte??n's Western Pacific Coast district. Maps and notes on the distribution of 14 significant distribution records are presented. Compared with bryophyte distribution in the Northern Hemisphere, the bryoflora of Simeonof Island primarily includes taxa of boreal (55%), temperate (20%), arctic (10%), and cosmopolitan (8%) distribution; 6% of the moss flora are western North America endemics. A description of the bryophytes present in the vegetation and habitat types is provided as is a quantitative analysis of the most frequently occurring bryophytes in crowberry heath.

In 1997, the National Marine Fisheries Service (NMFS) listed upper Columbia River steelhead trout (Oncorhynchus znykiss) as endangered. This action affected management of land-use activities along and within the Hanford Reach of the Columbia River, which flows through the U.S. Department of Energy (DOE) Hanford Site. Steelhead covered in this listing include all naturally spawned populations of steel-head and their progeny in streams in the Columbia River Basin upstream from the Yakima River to the United States/Canada border. The NMFS has identified a general listing of activities that could potentially result in harm to steelhead (62 FR 43937, August 18, 1997). One of these concerns includes land-use changes resulting in mass wasting or surface erosion. Landslide activity along the White Bluffs on the east ,side of Locke Island has redirected river flow into the island where substantial erosion has occurred. This erosion has exposed important anthropological and archaeological resources that were previously buried on the island. The DOE is working with affected tribes and other agencies to develop a plan for addressing the erosion of Locke Island. As part of this effort, the U.S. Army Corps of Engineers has prepared an assessment of potential alternatives to stabilize the erosion, including a no-action alternative. Steelhead historically spawned in the vicinity of Locke Island, but recent information on the occurrence of steelhead spawning or availability of spawning habitat was lacking. Therefore, the purpose of this study was to determine if steelhead spawned in the vicinity of Locke Island erosion and to evaluate the composition of substrate in the affected area. Surveys to document the occurrence of steelheads redds were conducted in Spring 1999. The surveys were conducted from the air as well as with the use of an underwater video camera. Neither aerial nor underwater surveys documented steelhead spawning within the survey area. Habitat surveys were

2012-04-01

Full Text Available Resumo Nosso objetivo é relatar um feto cuja confirmação diagnóstica de atresia de esôfago através da ressonância nuclear magnética (RNM levou à suspeita de síndrome de Edwards. A gestante apresentava 28 anos e veio inicialmente à consulta na medicina fetal com 24 semanas de gravidez. Possuía ultrassom fetal com polidrâmnio, artéria umbilical única e não visualização da bolha gástrica. A RNM fetal evidenciou a presença de uma estrutura similar a uma bolsa dilatada ao nível torácico, na topografia da porção proximal do esôfago, o que confirmou o diagnóstico de atresia de esôfago. Neste momento, suspeitou-se do diagnóstico de cromossomopatia, em especial, de síndrome de Edwards. Contudo, o exame de cariótipo não pôde ser realizado no momento. A ecocardiografia fetal de pouco antes do nascimento mostrou uma tetralogia de Fallot. A criança nasceu de parto cesáreo, com 33 semanas de gestação, pesando 1460 g. Observou-se na sua avaliação a presença de dismorfias como camptodactilia dos dedos das mãos e calcâneos proeminentes. A avaliação cariotípica confirmou a suspeita de síndrome de Edwards. Os exames complementares também confirmaram a presença de atresia de esôfago com fístula traqueoesofágica. A síndrome de Edwards é uma anormalidade cromossômica relativamente comum caracterizada por um espectro clínico bastante amplo e uma limitada sobrevida. A RNM fetal, por sua vez, tem o potencial de complementar a avaliação realizada pelo US na elucidação de algumas malformações maiores fetais, tal como a atresia de esôfago. Estas possuem o potencial de serem marcadores para anormalidades cromossômicas, tal como a síndrome de Edwards.

Emerging Churches in Post-Christian Canada

Directory of Open Access Journals (Sweden)

Steven Studebaker

2012-09-01

Full Text Available The traditional mainline and evangelical churches in Canada, as in most western countries, are either in decline or static. Taken as a measure of the future, the prospects for Christianity in Canada, and more broadly the West, are bleak. Post-Christian Canada, however, contains thriving alternative and innovative forms of church, often called ‘emerging’ churches. They take many forms of expression, but share common theological convictions. Based on site research and personal interviews, this article describes the various types and contexts of these churches in Canada. It then highlights three of their central theological characteristics. First, rejecting the ‘culture wars’ social involvement of Christendom churches, they embrace practices and initiatives that transform their local communities. Second, they embrace an incarnational and contextual understanding of Christian life and ministry. Eschewing mega-church franchise models, they endeavor to shape their ministry to the their local communities. Third, they adopt a comprehensive rather than compartmental spirituality.

In order to analyze energy self-sufficient island, example of a smaller island, connected to the power system of a bigger island with an undersea cable, was taken. Mounting substation 10/0,4 is situated on the island and for the moment it provides enough electricity using the medium voltage line. It is assumed that the island is situated on the north part of the Adriatic Sea. The most important problem that occurs on the island is the population drop that occurs for a significant number of years, therefore, life standard needs to be improved, and economic development needs to be encouraged immediately. Local authorities to stimulate sustainable development on the island through different projects, to breath in a new life to the island, open new jobs and attract new people to come live there. Because of the planned development and increase of the population, energy projects, planned as a support to sustainable development, and later achievement of the energy self-sufficiency, is described in this paper. Therefore, Rewisland methodology appliance is described taking into the account three possible scenarios of energy development. Each scenario is calculated until year 2030. Also, what is taken into the account is 100% usage of renewable sources of energy in 2030. Scenario PTV, PP, EE - This scenario includes installation of solar photovoltaic modules and solar thermal collectors on the buildings roofs, as well as well as implementation of energy efficiency on the island (replacement of the street light bulbs with LED lightning, replacement of the old windows and doors on the houses, as well as the installation of the thermal insulation). Scenario PV island - This scenario, similarly to the previous one, includes installation of solar photovoltaic modules and solar thermal collectors an the residential buildings, as well as the 2 MW photovoltaic power plant and ''Green Hotel'', a building that satisfies all of its energy needs completely from renewable energy sources

Rhode Island`s landfill and adjacent materials recovery facility (MRF) in Johnston, both owned by the quasi-public Rhode Island Resource Recovery Corp. (RIRRC, Johnston), serve the entire state. The $12-million recycling facility was built in 1989 next to the state`s sole landfill, the Central Landfill, which accepts only in-state trash. The MRF is operated for RIRRC by New England CRInc. (Hampton, N.H.), a unit of Waste Management, Inc. (WMI, Oak Brook, Ill.). It handles a wide variety of materials, from the usual newspaper, cardboard, and mixed containers to new streams such as wood waste, scrap metal, aseptic packaging (milk and juice boxes), and even textiles. State municipalities are in the process of adding many of these new recyclable streams into their curbside collection programs, all of which feed the facility.

Making progress: Petro-Canada's 1999 report in support of Canada's climate change voluntary challenge and registry

International Nuclear Information System (INIS)

1999-11-01

In 1998, Petro-Canada improved energy efficiency in both downstream and upstream sectors by 2% and 8% respectively, exceeding the 1998 targets. Petro-Canada is committed to maintaining a target of improved efficiency by 1% per year to 2005. Even though the company's production of crude oil, natural gas and refined products rose slightly in 1998, it succeeded in reducing its greenhouse gas emissions by 6% from 1997. Actions taken in 1998 cut more than 70,000 tonnes from its ongoing annual gas emissions and saved 1.3 million Gigajoules of energy. In total since 1990, Petro-Canada's initiatives have eliminated more than 1,300,000 tonnes of annual ongoing emissions, reducing the total greenhouse gas emissions to within 1% of its emissions in 1990, despite growth in production. Petro-Canada has allocated $4 million in capital funds specifically for energy efficiency projects in 2000. The company is continuing its initiatives in alternate fuels, and actively working with others seeking solutions. To enhance public awareness, it is funding a number of education projects related to climate change

Effects of Lakes on Wildfire Activity in the Boreal Forests of Saskatchewan, Canada

Directory of Open Access Journals (Sweden)

Scott E. Nielsen

2016-11-01

Full Text Available Large lakes can act as firebreaks resulting in distinct patterns in the forest mosaic. Although this is well acknowledged, much less is known about how wildfire is affected by different landscape measures of water and their interactions. Here we examine how these factors relate to historic patterns of wildfire over a 35-year period (1980–2014 for the boreal forest of Saskatchewan, Canada. This includes the amount of water in different-sized neighborhoods, the presence of islands, and the direction, distance, and shape of nearest lake of different sizes. All individual factors affected wildfire presence, with lake sizes ≥5000 ha and amount of water within a 1000-ha surrounding area the most supported spatial scales. Overall, wildfires were two-times less likely on islands, more likely further from lakes that were circular in shape, and in areas with less surrounding water. Interactive effects were common, including the effect of direction to lake as a function of distance from lakeshore and amount of surrounding water. Our results point to a strong, but complex, bottom-up control of local wildfire activity based on the configuration of natural firebreaks. In fact, fire rotation periods predicted for one area varied more than 15-fold (<47 to >700 years depending on local patterns in lakes. Old-growth forests within this fire-prone ecosystem are therefore likely to depend on the surrounding configuration of larger lakes.

Velocity Structure and 3D Finite Element Modeling for Critical Instability of Gas Hydrate-related Slipstream Submarine Slide, offshore Vancouver Island, Canada

Science.gov (United States)

LONG, S.; He, T.; Lan, K.; Spence, G.; Yelisetti, S.

2016-12-01

The previous study indicated that Slipstream submarine landslide is one of a gas hydrate-related slope failures on the frontal ridges of the Northern Cascadia accretionary margin, off Vancouver Island, Canada. The OBS data collected during SeaJade project were used to derive the subseafloor Vp & Vs structures. The anomalous high Vp of about 2.0 km/s at shallow depths of 100 (± 10) mbsf closely matches the estimated depth of the glide plane. The modelled Vs above the BSR at a depth of 265-275 mbsf is about 100-150 m/s higher than a theoretical 100% water saturated background value, indicating that the hydrate acts as part of the load-bearing matrix to increase the rigidity of the sediment. Also, the Vp & Vs above BSR both indicate a consistent 40% saturation of gas hydrate. On the basis of high accurate submarine bathymetry obtained by multibeam sounding system, the submarine landform before slump is reconstructed by comparing the slump headwall geometry with surrounding ridges. Using the elastic moduli determined from Vp & Vs, the stress status was calculated by the finite element method for different conditions and confirmed that the undersea sliding process related with gas hydrate starts from the toe of the slope and then progressively retreats to the place of current headwall, in a series of triangular blocks or wedges. The shear stress are then compared with the frame shear strength of geological model, which is critical for controlling slope stability of steep frontal ridges The simulation results found that the ridge was stable under its own weight, but gas hydrate saturation decrease and pore-water pressure increase will greatly reduce shear strength of sediments and may cause a landslide. Since the study area is in the earthquake belt, the large seismic acceleration will greatly affect pore pressure distribution within the ridge. The simulation results indicated that the shallow high-velocity gas hydrate layer coincident with glide plane depth is more

Pathogenicity island mobility and gene content.

Key goals towards national biosecurity include methods for analyzing pathogens, predicting their emergence, and developing countermeasures. These goals are served by studying bacterial genes that promote pathogenicity and the pathogenicity islands that mobilize them. Cyberinfrastructure promoting an island database advances this field and enables deeper bioinformatic analysis that may identify novel pathogenicity genes. New automated methods and rich visualizations were developed for identifying pathogenicity islands, based on the principle that islands occur sporadically among closely related strains. The chromosomally-ordered pan-genome organizes all genes from a clade of strains; gaps in this visualization indicate islands, and decorations of the gene matrix facilitate exploration of island gene functions. A %E2%80%9Clearned phyloblocks%E2%80%9D method was developed for automated island identification, that trains on the phylogenetic patterns of islands identified by other methods. Learned phyloblocks better defined termini of previously identified islands in multidrug-resistant Klebsiella pneumoniae ATCC BAA-2146, and found its only antibiotic resistance island.

Severe anaphylactoid reaction after the use of iodinated contrast media are rare but can contraindicate the use of contrast agent. It was the case of a 53-year-old woman suffering from symptomatic severe aortic stenosis, recused for cardiac surgery because of deleterious effects of chest-wall irradiation, with porcelain aorta. We decided to implant a 23-mm Edwards(®) SAPIEN(®) transcatheter aortic valve via a femoral route without using any contrast media. The implantation was successful after surgical approach of the femoral artery, transesophageal echocardiography guiding, and localization of native leaflets and coronary trunk with catheters. Immediate and one month post-interventional follow-up was favorable and echocardiography showed a good functioning of the aortic bioprosthesis. Although conventional angiography is the best way to visualize the good positioning of the valve before deployment, our case suggests that, in special situations, transfemoral implantation of an Edwards(®) SAPIEN(®) aortic bioprosthesis is feasible without any contrast injection.

Full Text Available We found Gastrodia fontinalis T. P. Lin in a bamboo forest from Takeshima Island, which is the northernmost island of the Ryukyu Islands in Japan. This species is apparently rare and was previously considered to be an endemic Taiwanese species. Because there are a few minor differences between the original description and our specimens collected in Takeshima Island, here we report Gastrodia fontinalis from Takeshima Island as the first record outside of Taiwan, with a description of the specimens from Takeshima Island.

Energy cascades in Canada

Energy Technology Data Exchange (ETDEWEB)

Hayden, A. C.; Brown, T. D.

1979-03-15

Combining energy uses in a cascade can result in significant overall reductions in fuel requirements. The simplest applications for a cascade are in the recovery of waste heat from existing processes using special boilers or turbines. Specific applications of more-complex energy cascades for Canada are discussed. A combined-cycle plant at a chemical refinery in Ontario is world leader in energy efficiency. Total-energy systems for commercial buildings, such as one installed in a school in Western Canada, offer attractive energy and operating cost benefits. A cogeneration plant proposed for the National Capital Region, generating electricity as well as steam for district heating, allows the use of a low-grade fossil fuel (coal), greatly improves energy-transformation efficiency, and also utilizes an effectively renewable resource (municipal garbage). Despite the widespread availability of equipment and technology of energy cascades, the sale of steam and electricity across plant boundaries presents a barrier. More widespread use of cascades will require increased cooperation among industry, electric utilities and the various levels of government if Canada is to realize the high levels of energy efficiency potential available.

Pipelines to eastern Canada

Otsason, J.

1998-01-01

This presentation focused on four main topics: (1) the existing path of pipelines to eastern Canada, (2) the Chicago hub, (3) transport alternatives, and (4) the Vector Pipeline' expansion plans. In the eastern Canadian market, TransCanada Pipelines dominates 96 per cent of the market share and is effectively immune to expansion costs. Issues regarding the attractiveness of the Chicago hub were addressed. One attractive feature is that the Chicago hub has access to multiple supply basins including western Canada, the Gulf Coast, the mid-continent, and the Rockies. Regarding Vector Pipelines' future plans, the company proposes to construct 343 miles of pipeline from Joliet, Illinois to Dawn, Ontario. Project description included discussion of some of the perceived advantages of this route, namely, extensive storage in Michigan and south-western Ontario, the fact that the proposed pipeline traverses major markets which would mitigate excess capacity concerns, arbitrage opportunities, cost effective expansion capability reducing tolls, and likely lower landed costs in Ontario. Project schedule, costs, rates and tariffs are also discussed. tabs., figs

Renewable energy islands in Europe

Energy Technology Data Exchange (ETDEWEB)

Oestergaard, Iben [ed.

1998-12-31

This publication includes a compiled presentation of various aspects concerning the possible transformation of some European islands into renewable energy communities and these projects were presented by a selection of pioneer islands at the first European Seminar on Renewable Energy Islands, held on the Danish island of Samsoee, 29-30 June 1998. This issue has increased in importance with the presentation of the ambitious EU-White Paper: `Energy for the future: Renewable Sources of Energy` which was adopted in 1998. One of the key elements of the strategy for an accelerated implementation of renewable energy is to transform 100 localities within Europe into communities which are to be 100% self-sufficient with renewable energy before 2010. In line with this strategy, the Danish Government appointed the island of Samsoe towards the end of 1997 to be the first `official` Danish, renewable energy island. This is to serve as a demonstration project for other local communities, both in Denmark as well as in the rest Europe. Gothland, Madeira, Canary Islands, Cape Verde, Arki, Crete, Minorca and Orkney Islands were represented. Environmental advantages of wind, solar and wave power for distant island communities were indicated. Serious savings would be achieved by limitation of fossil fuel import and utilization of local resources. (EG)

Barrier islands are dynamic environments due to their position at the land-sea interface. Storms, waves, tides, currents, and relative sea-level rise are powerful forces that shape barrier island geomorphology and habitats (for example, beach, dune, marsh, and forest). Hurricane Katrina in 2005 and the Deep Water Horizon oil spill in 2010 are two major events that have affected habitats and natural resources on Dauphin Island, Alabama. The latter event prompted a collaborative effort between the U.S. Geological Survey, the U.S. Army Corps of Engineers, and the State of Alabama funded by the National Fish and Wildlife Foundation to investigate viable, sustainable restoration options that protect and restore the natural resources of Dauphin Island, Alabama.In order to understand the feasibility and sustainability of various restoration scenarios, it is important to understand current conditions on Dauphin Island. To further this understanding, a detailed 19-class habitat map for Dauphin Island was produced from 1-foot aerial infrared photography collected on December 4, 2015, and lidar data collected in January 2015. We also conducted a ground survey of habitat types, vegetation community structure, and elevations in November and December 2015. These products provide baseline data regarding the ecological and general geomorphological attributes of the area, which can be compared with observations from other dates for tracking changes over time.

Changing patterns of referral and management of hypertrophic pyloric stenosis (HPS) in North America have recently been described. Comfort with perioperative management, anesthesia, and corrective surgery have been cited as reasons for these changes. Our primary objective was to assess pyloromyotomy outcomes between different hospital types across Canada. The secondary objective was to geospatially map all pyloromyotomies to identify regions of higher HPS incidence across Canada. Data of all pyloromyotomies done between 2011 and 2013 were acquired from Canadian Institute for Health Information (CIHI). Complication rates and length of hospital stay (LOS) were analyzed. Postal codes for each patient were used to geospatially map regions of higher HPS incidence. A total of 1261 pyloromyotomies were assessed. There was no difference in LOS or complication rates between different hospital types or surgeon group. Open pyloromyotomies were done in 75% of the cases. Several regions of higher HPS incidence were identified across Canada. This study found no difference in complication rate or LOS stay between hospital type and surgeon type across Canada. This may reflect a previously identified referral trend in the United States towards pediatric centers. Several regions of higher HPS incidence were identified, and may aid in identifying genetic elements causing HPS. 2c. Crown Copyright © 2017. Published by Elsevier Inc. All rights reserved.

Full Text Available O processo de consolidação do modo de produção fabril paulatinamente configurou uma clara distinção entre a jornada de trabalho e um tempo livre. Que relação se pode estabelecer entre essa nova dinâmica dos tempos sociais e as tensões relacionadas à construção de um novo conjunto de comportamentos considerados adequados para a consolidação do capitalismo? Esse estudo tem por objetivo discutir o trato dessa questão na obra de Edward Palmer Thompson. Parece possível afirmar que, para ele, o controle do tempo do não-trabalho e das práticas de lazer foi compreendido como uma dimensão fundamental para garantir o "progresso".

Auger, Nathalie; Le Serbon, Emilie; Rostila, Mikael

2015-06-01

Sweden and Canada are known for quality of living and exceedingly high life expectancy, but recent data on how these countries compare are lacking. We measured life expectancy in Canada and Sweden during the past decade, and identified factors responsible for changes over time. We calculated life expectancy at birth for Canada and Sweden annually from 2000 to 2010, and determined the ages and causes of death responsible for the gap between the two countries using Arriaga's method. We determined how population growth, ageing, and mortality influenced the number of deaths over time. During 2000-2010, life expectancy in Canada caught up with Sweden for men, and surpassed Sweden by 0.4 years for women. Sweden lost ground owing to a slower reduction in circulatory and tumour mortality after age 65 years compared with Canada. Nonetheless, population ageing increased the number of deaths in Canada, especially for mental and nervous system disorders. In Sweden, the number of deaths decreased. In only one decade, life expectancy in Canada caught up and surpassed Sweden due to rapid improvements in circulatory and tumour mortality. Population ageing increased the number of deaths in Canada, potentially stressing the health care system more than in Sweden. © 2015 the Nordic Societies of Public Health.

Climate Change and Malaria in Canada: A Systems Approach

Directory of Open Access Journals (Sweden)

L. Berrang-Ford

2009-01-01

Full Text Available This article examines the potential for changes in imported and autochthonous malaria incidence in Canada as a consequence of climate change. Drawing on a systems framework, we qualitatively characterize and assess the potential direct and indirect impact of climate change on malaria in Canada within the context of other concurrent ecological and social trends. Competent malaria vectors currently exist in southern Canada, including within this range several major urban centres, and conditions here have historically supported endemic malaria transmission. Climate change will increase the occurrence of temperature conditions suitable for malaria transmission in Canada, which, combined with trends in international travel, immigration, drug resistance, and inexperience in both clinical and laboratory diagnosis, may increase malaria incidence in Canada and permit sporadic autochthonous cases. This conclusion challenges the general assumption of negligible malaria risk in Canada with climate change.
