    The region of Churchill, Manitoba, contains a wide variety of habitats representative of both the boreal forest and arctic tundra and has been used as a model site for biodiversity studies for nearly seven decades within Canada. Much previous work has been done in Churchill to study the Daphnia pulex species complex in particular, but no study has completed a wide-scale survey on the crustacean species that inhabit Churchill's aquatic ecosystems using molecular markers. We have employed DNA barcoding to study the diversity of the Branchiopoda (Crustacea) in a wide variety of freshwater habitats and to determine the likely origins of the Churchill fauna following the last glaciation. The standard animal barcode marker (COI) was sequenced for 327 specimens, and a 3% divergence threshold was used to delineate potential species. We found 42 provisional and valid branchiopod species from this survey alone, including several cryptic lineages, in comparison with the 25 previously recorded from previous ecological works. Using published sequence data, we explored the phylogeographic affinities of Churchill's branchiopods, finding that the Churchill fauna apparently originated from all directions from multiple glacial refugia (including southern, Beringian, and high arctic regions). Overall, these microcrustaceans are very diverse in Churchill and contain multiple species complexes. The present study introduces among the first sequences for some understudied genera, for which further work is required to delineate species boundaries and develop a more complete understanding of branchiopod diversity over a larger spatial scale.

    We examined factors influencing Canada Goose (Branta canadensis interior) annual nest success, including the relative abundance of collared lemmings (Dicrostonyx richardsoni), arctic fox (Alopex lagopus) den occupancy, nest density, and spring phenology using data collected during annual Canada Goose breeding area surveys at Cape Churchill, Manitoba. Nest density and arctic fox den occupancy strongly influenced Canada Goose nest success. High nest density resulted in higher nest success and high den occupancy reduced nest success. Nest success was not influenced by lemming abundance in the current or previous year as predicted by the "bird-lemming" hypothesis. Reducing arctic fox abundance through targeted management increased nest survival of Canada Geese; a result that further emphasizes the importance of arctic fox as nest predators in this system. The spatial distribution of nest predators, at least for dispersed-nesting geese, may be most important for nest survival, regardless of the abundance of small mammals in the local ecosystem. Further understanding of the factors influencing the magnitude and variance in arctic fox abundance in this region, and the spatial scale at which these factors are realized, is necessary to fully explain predator-prey-alternative prey dynamics in this system. ?? 2011 by the Wilson Ornithological Society.

    Regular, multiannual cycles observed in the population abundance of small mammals in many arctic and subarctic ecosystems have stimulated substantial research, particularly among population ecologists. Hypotheses of mechanisms generating regular cycles include predator-prey interactions, limitation of food resources, and migration or dispersal, as well as abiotic factors such as cyclic climatic variation and environmental stochasticity. In 2004 and 2005, we used indirect methods to estimate trends in population size of Richardson's collared lemmings (Dicrostonyx richardsoni) retrospectively, and evaluated the extent of synchrony between lemming populations at 2 coastal tundra study areas separated by approximately 60 km near Cape Churchill, Manitoba, Canada. We collected scars on willow plants (Salix) resulting from lemming feeding. Ages of scars ranged from 0 to 13 years at both study areas. Scar-age frequency appeared cyclic and we used nonlinear Poisson regression to model the observed scar-age frequency. Lemming populations cycled with 2.8-year periodicity and the phase of the cycle was synchronous between the 2 study areas. We suggest that our approach could be applied in multiple settings and may provide the most efficient way to gather data on small mammals across both space and time in a diversity of landscapes. ?? 2008 American Society of Mammalogists.

    The North American Trichoptera larvae are poorly known at the species level, despite their importance in the understanding of freshwater fauna and critical use in biomonitoring. This study focused on morphological diagnoses for larvae occurring in the Churchill, Manitoba area, representing the largest larval association effort for the caddisflies at any given locality thus far. The current DNA barcode reference library of Trichoptera (available on the Barcode of Life Data Systems) was utilized to provide larval-adult associations. The present study collected an additional 23 new species records for the Churchill area, increasing the total Trichoptera richness to 91 species. We were able to associate 62 larval taxa, comprising 68.1% of the Churchill area Trichoptera taxa. This endeavor to identify immature life stage for the caddisflies enabled the development of morphological diagnoses, production of photographs and an appropriate taxonomic key to facilitate larval species analyses in the area. The use of DNA for associations of unknown larvae with known adults proved rapid and successful. This method should accelerate the state-of-knowledge for North American Trichoptera larvae as well as other taxonomic lineages. The morphological analysis should be useful for determination of material from the Churchill area.

    Chmelnitsky, Elly Golda

    The investigation of a species' repertoire and the contexts in which different calls are used is central to understanding vocal communication among animals. Beluga whale, Delphinapterus leucas, calls were classified and described in association with behaviours, from recordings collected in the Churchill River, Manitoba, during the summers of 2006-2008. Calls were subjectively classified based on sound and visual analysis into whistles (64.2% of total calls; 22 call types), pulsed or noisy calls (25.9%; 15 call types), and combined calls (9.9%; seven types). A hierarchical cluster analysis, using six call measurements as variables, separated whistles into 12 groups and results were compared to subjective classification. Beluga calls associated with social interactions, travelling, feeding, and interactions with the boat were described. Call type percentages, relative proportions of different whistle contours (shapes), average frequency, and call duration varied with behaviour. Generally, higher percentages of whistles, more broadband pulsed and noisy calls, and shorter calls (studies on call meaning and function.

  6. Demography of a breeding population of whimbrel (Numenius phaeopus) near Churchill, Manitoba, Canada

    Perz, Johanna

    I used a GIS raster layer of an area in the Churchill, Manitoba region to investigate the effect of breeding habitat on demography and density of Whimbrel from 2010 through 2013. Program MARK was used to quantify adult and daily nest survival. Apparent annual survival of 0.73 +/- 0.06 SE (95% CI = 0.60-0.83) did not significantly differ between sexes or habitats and was lower than expected based on longevity records and estimates for other large-bodied shorebirds. Nest success, corrected for exposure days, was highly variable, ranging from a low of 3% (95% CI = 0-12%) in 2011 to a high of 71% (95% CI = 54-83%) in 2013. The highest rate of nest survival occurred in the spring with the warmest mean temperature. I developed a generalized linear model (GLM) with a negative-binomial distribution from random plots that were surveyed for abundance to extrapolate a local breeding population size of 410 +/- 230 SE and density of 3.2 birds per square km +/- 1.8 SE. The result of my study suggests that other aspects of habitat not captured by the land cover categories may be more important to population dynamics.

    Full Text Available Ponds and lakes distributed across northern treeline in the Hudson Bay Lowlands near Churchill (Manitoba were revisited to analyse and document the local ecoclimatic and limnological changes that occurred over the period 1997-2012. Our analyses revealed that single events may cause significant changes in salinity, pH and silicate content because of the limited buffer capacity of the inter-connected waters. Planktic freshwater microcrustaceans (Cladocera presented less diverse assemblages and appeared to favour waters that are situated in the boreal forest, while the diversity of benthic species assemblages (Cladocera and Ostracoda was highest in waters located closer to the coastline and in open tundra vegetation. We identified three species that are distinctive for the boreal ecozone (i.e., Candona acuta, Can. acutula and Can. decora and two species (i.e., Tonnacypris glacialis and Can. rawsoni that are elements of (sub-arctic landscapes and potentially endangered as the northern treeline expands due to rapid warming. These species are thought to be useful indicators for future ecosystem quality assessments and/or ecosystem service management programs. Our findings were compared to other studies completed in the boreal Yukon Territory and revealed that species diversity is closely linked to landscape history.

  8. Anurans in a Subarctic Tundra Landscape Near Cape Churchill, Manitoba

    2008-01-01

    Distribution, abundance, and habitat relationships of anurans inhabiting subarctic regions are poorly understood, and anuran monitoring protocols developed for temperate regions may not be applicable across large roadless areas of northern landscapes. In addition, arctic and subarctic regions of North America are predicted to experience changes in climate and, in some areas, are experiencing habitat alteration due to high rates of herbivory by breeding and migrating waterfowl. To better understand subarctic anuran abundance, distribution, and habitat associations, we conducted anuran calling surveys in the Cape Churchill region of Wapusk National Park, Manitoba, Canada, in 2004 and 2005. We conducted surveys along ~l-km transects distributed across three landscape types (coastal tundra, interior sedge meadow-tundra, and boreal forest-tundra interface) to estimate densities and probabilities of detection of Boreal Chorus Frogs (Pseudacris maculata) and Wood Frogs (Lithobates sylvaticus). We detected a Wood Frog or Boreal Chorus Frog on 22 (87%) of 26 transects surveyed, but probability of detection varied between years and species and among landscape types. Estimated densities of both species increased from the coastal zone inland toward the boreal forest edge. Our results suggest anurans occur across all three landscape types in our study area, but that species-specific spatial patterns exist in their abundances. Considerations for both spatial and temporal variation in abundance and detection probability need to be incorporated into surveys and monitoring programs for subarctic anurans.

    A variety of methods are available to calculate daily mean temperature. We explore how the difference between two commonly used methods provides insight into the local climate of Churchill, Manitoba. In particular, we found that these differences related closely to seasonal fog. A strong statistically significant correlation was found between the fog frequency (hours per day) and the diurnal temperature asymmetries of the surface temperature using the difference between the min/max and 24-h methods of daily temperature calculation. The relationship was particularly strong for winter, spring and summer. Autumn appears to experience the joint effect of fog formation and the radiative effect of snow cover. The results of this study suggests that subtle variations of diurnality of temperature, as measured in the difference of the two mean temperature methods of calculation, may be used as a proxy for fog detection in the Hudson Bay region. These results also provide a cautionary note for the spatial analysis of mean temperatures using data derived from the two different methods particularly in areas that are fog prone.

    Full Text Available Abstract Background Because arctic plant communities are highly vulnerable to climate change, shifts in their composition require rapid, accurate identifications, often for specimens that lack diagnostic floral characters. The present study examines the role that DNA barcoding can play in aiding floristic evaluations in the arctic by testing the effectiveness of the core plant barcode regions (rbcL, matK and a supplemental ribosomal DNA (ITS2 marker for a well-studied flora near Churchill, Manitoba. Results This investigation examined 900 specimens representing 312 of the 354 species of vascular plants known from Churchill. Sequencing success was high for rbcL: 95% for fresh specimens and 85% for herbarium samples (mean age 20 years. ITS2 worked equally well for the fresh and herbarium material (89% and 88%. However, sequencing success was lower for matK, despite two rounds of PCR amplification, which reflected less effective primer binding and sensitivity to the DNA degradation (76% of fresh, 45% of herbaria samples. A species was considered as taxonomically resolved if its members showed at least one diagnostic difference from any other taxon in the study and formed a monophyletic clade. The highest species resolution (69% was obtained by combining information from all three genes. The joint sequence information for rbcL and matK distinguished 54% of 286 species, while rbcL and ITS2 distinguished 63% of 285 species. Discrimination of species within Salix, which constituted 8% of the flora, was particularly problematic. Despite incomplete resolution, the barcode results revealed 22 misidentified herbarium specimens, and enabled the identification of field specimens which were otherwise too immature to identify. Although seven cases of ITS2 paralogy were noted in the families Cyperaceae, Juncaceae and Juncaginaceae, this intergenic spacer played an important role in resolving congeneric plant species at Churchill.

    We examined microsite characteristics at 21 Lapland Longspur (Calcarius lapponicus) nests and land cover types in which they occurred in Wapusk National Park, Cape Churchill, Manitoba. Nests were located in four of six physiographic-vegetation land-cover types. Regardless of land-cover type, all but one nest was built on a pressure ridge or mound. Nests were built midway between the bottom and top of ridges or mounds with steeper slopes than was randomly available. Longspur nests had a distinctive southwest orientation (P < 0.001). Longspurs selected nest sites that consisted of comparatively greater amounts of shrub species and lesser amounts of moss than were randomly available. Nests were generally well concealed by vegetation (mean = 67.0%) and concealment was negatively associated with amount of graminoid species at the nest (P = 0.0005). Our nesting habitat data may facilitate a better understanding of breeding Lapland Longspur habitat requirements, and potential impacts of habitat degradation by increasing Snow Goose (Chen caerulescens) populations in the study area.

    Arctic ecosystems, especially those near transition zones, are expected to be strongly impacted by climate change. Because it is positioned on the ecotone between tundra and boreal forest, the Churchill area is a strategic locality for the analysis of shifts in faunal composition. This fact has motivated the effort to develop a comprehensive biodiversity inventory for the Churchill region by coupling DNA barcoding with morphological studies. The present study represents one element of this effort; it focuses on analysis of the spider fauna at Churchill. 198 species were detected among 2704 spiders analyzed, tripling the count for the Churchill region. Estimates of overall diversity suggest that another 10-20 species await detection. Most species displayed little intraspecific sequence variation (maximum Churchill, but the other species represents a range extension from the USA. The first description of the female of S. monticola was also presented. As well, one probable new species of Alopecosa (Lycosidae) was recognized. This study provides the first comprehensive DNA barcode reference library for the spider fauna of any region. Few cryptic species of spiders were detected, a result contrasting with the prevalence of undescribed species in several other terrestrial arthropod groups at Churchill. Because most (97.5%) sequence clusters at COI corresponded with a named taxon, DNA barcoding reliably identifies spiders in the Churchill fauna. The capacity of DNA barcoding to enable the identification of otherwise taxonomically ambiguous specimens (juveniles, females) also represents a major advance for future monitoring efforts on this group.

    Southern Indian and Issett Lakes in northern Manitoba were flooded in 1976 as part of Manitoba Hydro's Churchill River diversion project. Fish were collected from 1975 to 1988 from five regional sites on the lakes to examine the effects of impoundment and river diversion on muscle mercury concentrations. Raw data for individual fish caught in 1987 and 1988 are presented, along with means and analyses calculated over the entire 1975-1988 study period. Mercury concentrations in whitefish, pike, and walleye increased significantly after impoundment. Whitefish mercury levels peaked in 1978 and have since declined to near pre-flooding levels. Northern pike and walleye mercury levels were much higher than for whitefish. Pike mercury concentrations showed no indication of declining after 12 years of impoundment, but walleye mercury levels at 2 of the 5 Southern Indian Lake sites declined from maximum recorded levels. Significant variability in fish mercury concentrations was noted both from year to year and among the sites. It is suggested that site-to-site variations are due to varying conditions in the reservoir which stimulate mercury methylation. Since there appears to be an ongoing long-term source of mercury and organic material from the eroding shorelines, pike and walleye mercury concentrations are expected to remain high for many years. 25 refs., 7 figs., 20 tabs

    A detailed summary is provided from five major water quality studies undertaken in northern Manitoba to assess the effects of hydroelectric projects on water quality. Physical changes occurring with the area affected by both the Churchill River diversion and Lake Winnipeg regulation have led to water quality changes in many cases. Phosphorus appeared to increase at some sites while decreasing at others, reflecting a new balance between erosion of new P sources and later uptake or deposition. Color declined at all sites except at Red Head Rapids. Turbidity increased in Southern Indian Lake and in the Burntwood River at Thompson in response to the Churchill diversion, but turbidity has historically exceeded drinking water quality objectives. It is unclear whether the observed changes in water chemistry may have the potential to directly impact aquatic life and wildlife. A major limitation of the water quality data set is the lack of pre-development data for many of the trace elements analyzed. Relative to an upstream reference site, concentrations of Cu, Pb, and Zn were slightly higher at some sites affected by hydroelectric development, but it is not known whether this condition existed prior to development. Exceedances of water quality objectives for some trace elements occurred intermittently at some sites but it is not possible to determine whether these exceedances occurred infrequently historically as a result of natural variability. 34 refs., 1 fig., 13 tabs

    2012-07-01

    Full Text Available RADARSAT and ERS-2 data collected at multiple incidence angles are used to characterize the seasonal variations in the backscatter of snow-covered landscapes in the northern Hudson Bay Lowlands during the winters of 1997/98 and 1998/99. The study evaluates the usefulness of C-band SAR systems for retrieving the snow water equivalent under dry snow conditions in the forest–tundra ecotone. The backscatter values are compared against ground measurements at six sampling sites, which are taken to be representative of the land-cover types found in the region. The contribution of dry snow to the radar return is evident when frost penetrates the first 20 cm of soil. Only then does the backscatter respond positively to changes in snow water equivalent, at least in the open and forested areas near the coast, where 1-dB increases in backscatter for each approximate 5–10 mm of accumulated water equivalent are observed at 20–31° incidence angles. Further inland, the backscatter shows either no change or a negative change with snow accumulation, which suggests that the radar signal there is dominated by ground surface scattering (e.g., fen when not attenuated by vegetation (e.g., forested and transition. With high-frequency ground-penetrating radar, we demonstrate the presence of a 10–20-cm layer of black ice underneath the snow cover, which causes the reduced radar returns (−15 dB and less observed in the inland fen. A correlation between the backscattering and the snow water equivalent cannot be determined due to insufficient observations at similar incidence angles. To establish a relationship between the snow water equivalent and the backscatter, only images acquired with similar incidence angles should be used, and they must be corrected for both vegetation and ground effects.

    2009-01-01

    Background This study reports progress in assembling a DNA barcode reference library for Ephemeroptera, Plecoptera, and Trichoptera ("EPTs") from a Canadian subarctic site, which is the focus of a comprehensive biodiversity inventory using DNA barcoding. These three groups of aquatic insects exhibit a moderate level of species diversity, making them ideal for testing the feasibility of DNA barcoding for routine biotic surveys. We explore the correlation between the morphological species delineations, DNA barcode-based haplotype clusters delimited by a sequence threshold (2%), and a threshold-free approach to biodiversity quantification--phylogenetic diversity. Results A DNA barcode reference library is built for 112 EPT species for the focal region, consisting of 2277 COI sequences. Close correspondence was found between EPT morphospecies and haplotype clusters as designated using a standard threshold value. Similarly, the shapes of taxon accumulation curves based upon haplotype clusters were very similar to those generated using phylogenetic diversity accumulation curves, but were much more computationally efficient. Conclusion The results of this study will facilitate other lines of research on northern EPTs and also bode well for rapidly conducting initial biodiversity assessments in unknown EPT faunas.

    2016-04-01

    Tyndall Stone is a distinctively mottled and highly fossiliferous dolomitic limestone that belongs to the Selkirk Member of the Red River Formation, of Late Ordovician (Katian) age. It has been quarried at Garson, Manitoba, 37 km northeast of Winnipeg, since 1895, although other quarries in the area go back to 1832. Tyndall Stone, so named because it was shipped by rail from nearby Tyndall, is currently produced by Gillis Quarries Limited. It has various uses as a dimension stone. Large slabs, most often cut parallel to bedding, face the exterior or interior of many important buildings such as the Parliament Buildings and the Canadian Museum of Civilization in the Ottawa area, the Empress Hotel in Victoria, and the provincial legislatures in Winnipeg and Regina, as well as many commercial buildings especially in the Canadian prairies. At the quarries, the stone is cut vertically, using eight foot (2.44 m) diameter saws mounted on one hundred foot (30.5 m) tracks, then split into 6-8 tonne blocks that are moved using front-end loaders. Gillis Quarries operates a large finishing plant with an area of about 4000 m2. Stone is processed along advanced cutting lines that feature eight primary saws and six gantry saw stations, allowing it to be made into a variety of sizes, shapes, and finishes. The Selkirk Member is 43 m thick and the stone is extracted from a 6-8 m thick interval within the lower part. The upper beds tend to be more buff-coloured than the grey lower beds due to weathering by groundwater. The stone is massive, but extracted blocks are less than ~1m thick due to splitting along stylolites. Consisting of bioturbated wackestone to packstone, the Tyndall Stone was deposited in a shallow-marine environment within the photic zone, in the central part of the vast equatorial epicontinental sea that covered much of Laurentia. Scattered thin, bioclastic grainstone lenses record brief, low-energy storm events. The distinctive mottles are formed by dolomitized

    During the first wave of the H1N1 influenza pandemic in 2009, Aboriginal populations in Canada experienced disproportionate rates of infection, particularly in the province of Manitoba. To protect those thought to be most at-risk, health authorities in Manitoba listed all Aboriginal people, including Metis, among those able to receive priority access to the novel vaccine when it first became available. Currently, no studies exist that have investigated the attitudes, influences, and vaccine behaviors among Aboriginal communities in Canada. This paper is the first to systematically connect vaccine behavior with the attitudes and beliefs that influenced Metis study participants' H1N1 vaccine decision-making. Researchers held focus groups (n = 17) with Metis participants in urban, rural, and remote locations of Manitoba following the conclusion of the H1N1 pandemic. Participants were asked about their vaccination decisions and about the factors that influenced their decisions. Following data collection, responses were coded into the broad categories of a social-ecological model, nuanced by categories stemming from earlier research. Responses were then quantified to show the most influential factors in positively or negatively affecting the vaccine decision. Media reporting, the influence of peer groups, and prioritization all had positive and negative influential effects on decision making. Whether vaccinated or not, the most negatively influential factors cited by participants were a lack of knowledge about the vaccine and the pandemic as well as concerns about vaccine safety. Risk of contracting H1N1 influenza was the biggest factor in positively influencing a vaccine decision, which in many cases trumped any co-existing negative influencers. Metis experiences of colonialism in Canada deeply affected their perceptions of the vaccine and pandemic, a context that health systems need to take into account when planning response activities in the future.

    Full Text Available The 13th North American Caribou Workshop which was held in Winnipeg, Manitoba, was a great success with more than 400 participants: people from Canada, the United States, Norway and Greenland, representatives from co-management and resource management boards across North America, First Nations, Inuit and Inuvialuit, governmental and non-governmental organisations, private companies, researchers, students and youth. The theme of the Workshop was Sustaining Caribou and their Landscapes – Knowledge to Action and the intent of the organizers was twofold: first, to provide participants with the opportunity to share scientific and traditional knowledge on different subspecies and ecotypes of Rangifer across the circumpolar North, the particularities of the different landscapes and land use management issues; second, to explore innovative ways to transfer knowledge to action, ensuring the long-term persistence of Rangifer throughout its range through the development of better governance structures, sound policies and effective communication.

    1984-07-01

    A suite of borehole-geophysical logs, supported by core data, was used to describe the rock matrix and fractures in a granitic pluton near Lac du Bonnet, Manitoba, Canada. The site is being developed by Atomic Energy of Canada Limited, as an underground research laboratory to conduct geotechnical research and to validate predictive models as part of Canada's nuclear-fuel, waste-management program. However, the site is not planned to be used for waste disposal. Geophysical well logs were used to distinguish and correlate rock types and fractures between drill holes. Two significant fracture zones that are two of the major zones of ground-water movement at the site were identified by acoustic-televiewer logs. A new heat-pulse flowmeter provided repeatable measurements of very low-velocity, vertical flow in drill holes which enabled the identification of specific fractures that were transmitting water. Borehole gamma spectra showed that some fractures are enriched in uranium, and others may be depleted. This study demonstrates some of the advantages of synthesizing available borehole-geophysical logs at a site in fractured plutonic rocks and indicates how this information can contribute to an understanding of the geophysical conditions at the site

    The late-Quaternary paleoenvironmental history of the western Hudson Bay region of Subarctic Canada is poorly constrained. Here, we present a regional overview of the post-glacial history of eight lakes which span the forest-tundra biome in northern Manitoba. We show that during the penultimate drainage phase of Lake Agassiz the lake water had an estimated pH of ∼6.0, with abundant quillwort (Isöetes spp.) along the lakeshore and littoral zone and some floating green algae (Botryococcus spp. and Pediastrum sp.). Based on multiple sediment proxies, modern lake ontogeny in the region commenced at ∼7500 cal yrs BP. Pioneering diatom communities were shaped by the turbid, higher alkalinity lake waters which were influenced by base cation weathering of the surrounding till following Lake Agassiz drainage. By ∼7000 cal yrs BP, soil development and Picea spp. establish and the lakes began a slow trajectory of acidification over the remaining Holocene epoch. The natural acidification of the lakes in this region is slow, on the order of several millennia for one pH unit. Each of the study lakes exhibit relatively stable aquatic communities during the Holocene Thermal Maximum, suggesting this period is a poor analogue for modern climatic changes. During the Neoglacial, the beginning of the post-Little Ice Age period represents the most significant climatic event to impact the lakes of N. Manitoba. In the context of regional lake histories, the rate of diatom floristic change in the last 200-300 years is unprecedented, with the exception of post-glacial lake ontogeny in some of the lakes. For nearly the entire history of the lakes in this region, there is a strong linkage between landscape development and the aquatic ecosystems; however this relationship appears to become decoupled or less strong in the post-LIA period. Significant 20th century changes in the aquatic ecosystem cannot be explained wholly by changes in the terrestrial ecosystem, suggesting that future

    We examined wolf (Canis lupus) blood and fecal samples from the Riding Mountain National Park (RMNP) region of Manitoba, Canada. In 601 fecal samples collected during two study periods in RMNP and the Duck Mountain Provincial Park and Forest (DMPPF) we found gastrointestinal helminth eggs from Alaria sp. (15.5%), Capillaria sp. (1.0%), taeniid tapeworms (30.8%), Toxascaris sp. (1.7%), Toxocara sp. (0.2%), Trichuris sp. (2.2%), and Moniezia sp. (0.5%). In addition, we found Demodex sp. (0.2%) and the protozoal cysts/oocysts of Sarcocystis sp. (37.3%), Cryptosporidium sp. (1.2%), coccidia (Isospora sp. or Eimeria sp.) (1.7%), and Giardia sp. (29.5%). No fecal shedding of canine parvovirus (CPV, n=387) was detected. All 18 blood samples collected in RMNP showed CPV exposure and eight of 18 blood samples indicated canine distemper virus (CDV) exposure. One wolf died from CDV. Our results are consistent with previous findings on pathogens affecting wolves and with high Giardia sp. prevalence in wolves inhabiting agricultural regions.

    The migration and behaviour of I was investigated in a sphagnum bog on the precambrian Shield in eastern Manitoba, Canada. A 6 M solution of K1 was released at the base of the bog to simulate a pulse discharge of contaminated groundwater from a fracture in the granitic rock. A network of piezometer tubes was used to monitor the dispersion of the I and the groundwater chemistry over 1 year. Cores of peat were also taken for analysis to supplement the groundwater data and to investigate the sorption of I. The introduced I dispersed 2 m horizontally and 1 m vertically within a month. After this, the system stabilized and further migration was insignificant. The pattern of I dispersion indicated that the bog hydrology was very complex with flow directions changing substantially with depth. The groundwater concentrations of the major cations rose in response to the mass action effect of K displacing them from reaction sites in the peat. Humic materials in the groundwater decreased in size after the KI release and returned to their pre-release conformation one month later. The geometric mean soil distribution coefficient value, K d , for I in the bog was 1.361/kg, but it was strongly related to pore water concentration. Thus, a single K d value was insufficient for describing the system. (author)

    The province of Manitoba, Canada, with a population of approximately 1.3 million, has been experiencing increased incidence of syphilis cases since 2015. In this study, we examined the detection of Treponema pallidum DNA in 354 clinical samples from 2012 to 2016, and determined molecular types and mutations conferring resistance to azithromycin in the polymerase chain reaction (PCR)-positive samples. T. pallidum DNA detection was done by PCR amplification of tpp47, bmp, and polA genes. Syphilis serology results were reviewed for the PCR-positive cases. Molecular typing of syphilis strains was done by analysis of the T, pallidum arp, tpr, and tp0548 gene targets as well as partial sequencing of the 23S rRNA gene for azithromycin resistance. Of the 354 samples tested, 74 individual cases were PCR positive. A result from the treponemal antibody chemiluminescent microparticle immunoassay test was positive in 72 of these cases and that from the Venereal Disease Research Laboratory testing was positive in 66. Mutations conferring resistance to azithromycin were found in all 74 PCR-positive samples. Molecular typing was completed on 57 PCR-positive samples, and 12 molecular types were identified with 14d/g found in 63.2%. Increased strain diversity was observed with 8 molecular types detected in 2016, whereas only 2 to 3 types were found in 2012 to 2014. A patient with 2 episodes of infection 9 months apart caused by different molecular strain types was also identified. The finding of an increase in genetic diversity in the strains in this study and an increase in macrolide resistance compared with previous Canadian reports highlighted the need for continued surveillance including strain characterization.

    The field of cohesive soil erosion is still not fully understood, in large part due to the many soil parameters that affect cohesive soil erodibility. This study is focused on two channels, 2-Mile and 8-Mile channels in northern Manitoba, Canada, that were built to connect Lake Winnipeg with Playgreen Lake and Playgreen Lake with Kiskikittogisu Lake, respectively. The banks of the channels consist of clay rich soils and alluvial deposits of layered clay, silts and sands. The study of erosion at the sites is further complicated because the flow-induced erosion is combined with the effects of significant wave action due to the large fetch length on the adjacent lakes, particularly Lake Winnipeg that is the seventh largest lake in North America. The study included three main components: field measurements, laboratory experiments and numerical modelling. Field measurements consisted of soil sampling from the banks and bed of the channels, current measurements and water sampling. Grab soil samples were used to measure the essential physical and electrochemical properties of the riverbanks, and standard ASTM Shelby tube samples were used to estimate the critical shear stress and erodibility of the soil samples using an erosion measurement device (EMD). Water samples were taken to estimate the sediment concentration profile and also to monitor changes in sediment concentration along the channels over time. An Acoustic Doppler Current Profiler (ADCP) was used to collect bathymetry and current data, and two water level gauges have been installed to record water levels at the entrance and outlet of the channels. The MIKE 21 NSW model was used to simulate waves using historical winds and measured bathymetry of the channels and lakes. Finally, results from the wave numerical model, laboratory tests and current measurement were used to estimate the effect of each component on erodibility of the cohesive banks.

    Full Text Available Based on minimal information, lakes in the western Canadian provinces of Manitoba (MB and Saskatchewan (SK have long been considered unaffected by acid rain. However, emissions of acidifying pollutants from MB smelters and oil sand processing in Alberta (AB may pose a developing threat. Surveys of 347 lakes located on geologically sensitive terrain in northern MB and SK were conducted to assess their acidification sensitivity and status. The survey domain (~193,000 km2 contained 81,494 lakes ≥1 ha in area. Small lakes dominated the inventory in terms of numbers, and large lakes dominated in terms of area. Survey lakes were selected using a stratified-random sampling design in 10 sampling blocks within the overall survey domain. Few lakes had pH <6, and only three (all in SK were acidic, i.e., Gran Alkalinity (Alk <0 μeq L–1. A broad range in lake sensitivity was apparent, and very sensitive lakes (low specific conductance, base cations and Alk were present in all sampling blocks. Dissolved organic carbon (DOC was an important constituent of many lakes. Critical loads (CL of acidity calculated using the Steady-State Water Chemistry model (SSWC revealed extremely low 5th percentile values for every block (range 1.9 to 52.7 eq ha–1 y–1. Block CL exceedances calculated using estimated S and N deposition for 2002 ranged from 54.5 to 909 eq ha–1 y–1. The largest exceedances were for sampling blocks located near smelter sources or downwind of the oil sands. Lake chemistry revealed by our surveys was compared to others conducted both nearby and outside Canada.

    The importance of effective translation of health research findings into action has been well recognized, but there is evidence to suggest that the practice of knowledge translation (KT) among health researchers is still evolving. Compared to research user stakeholders, researchers (knowledge producers) have been under-studied in this context. The goals of this study were to understand the experiences of health researchers in practicing KT in Manitoba, Canada, and identify their support needs to sustain and increase their participation in KT. Qualitative semi-structured interviews were conducted with 26 researchers studying in biomedical; clinical; health systems and services; and social, cultural, environmental and population health research. Interview questions were open-ended and probed participants' understanding of KT, their experiences in practicing KT, barriers and facilitators to practicing KT, and their needs for KT practice support. KT was broadly conceptualized across participants. Participants described a range of KT practice experiences, most of which related to dissemination. Participants also expressed a number of negative emotions associated with the practice of KT. Many individual, logistical, and systemic or organizational barriers to practicing KT were identified, which included a lack of institutional support for KT in both academic and non-academic systems. Participants described the presence of good relationships with stakeholders as a critical facilitator for practicing KT. The most commonly identified needs for supporting KT practice were access to education and training, and access to resources to increase awareness and promotion of KT. While there were few major variations in response trends across most areas of health research, the responses of biomedical researchers suggested a unique KT context, reflected by distinct conceptualizations of KT (such as commercialization as a core component), experiences (including frustration and lack of

    This study compares incidence and hospitalization rates for shigellosis between Indians and the rest of the population in Manitoba, Canada. It examines the relationship between shigellosis and environmental conditions on reserves. Rates were calculated with surveillance data and a survey of environmental infrastructure was done. Indians had shigellosis incidence and hospitalization rates that were 29 and 12 times as high, respectively, as those of the rest of the population. Household crowding, lack of piped water, and inadequate sewage disposal were significantly associated with an increased incidence of shigellosis on reserves. Many cases of shigellosis may be prevented by improving living conditions on Indian reserves.

    Genetically modified herbicide-tolerant (GMHT) oilseed rape (OSR; Brassica napus L.) was approved for commercial cultivation in Canada in 1995 and currently represents over 95% of the OSR grown in western Canada. After a decade of widespread cultivation, GMHT volunteers represent an increasing management problem in cultivated fields and are ubiquitous in adjacent ruderal habitats, where they contribute to the spread of transgenes. However, few studies have considered escaped GMHT OSR populations in North America, and even fewer have been conducted at large spatial scales (i.e. landscape scales). In particular, the contribution of landscape structure and large-scale anthropogenic dispersal processes to the persistence and spread of escaped GMHT OSR remains poorly understood. We conducted a multi-year survey of the landscape-scale distribution of escaped OSR plants adjacent to roads and cultivated fields. Our objective was to examine the long-term dynamics of escaped OSR at large spatial scales and to assess the relative importance of landscape and localised factors to the persistence and spread of these plants outside of cultivation. From 2005 to 2007, we surveyed escaped OSR plants along roadsides and field edges at 12 locations in three agricultural landscapes in southern Manitoba where GMHT OSR is widely grown. Data were analysed to examine temporal changes at large spatial scales and to determine factors affecting the distribution of escaped OSR plants in roadside and field edge habitats within agricultural landscapes. Additionally, we assessed the potential for seed dispersal between escaped populations by comparing the relative spatial distribution of roadside and field edge OSR. Densities of escaped OSR fluctuated over space and time in both roadside and field edge habitats, though the proportion of GMHT plants was high (93-100%). Escaped OSR was positively affected by agricultural landscape (indicative of cropping intensity) and by the presence of an

    The hydrogeologic characteristics of the granitic Lac du Bonnet batholith in southeastern Manitoba have been studied since 1978, as part of AECL's program to assess the concept of disposing of Canada's nuclear fuel waste deep within plutonic rocks of the Canadian Shield (Davison et al. 1994a). These studies have included an extensive program of drilling, logging, testing, sampling and monitoring in 19 deep surface boreholes drilled at Grid areas located across the Lac du Bonnet batholith, at the Whiteshell Laboratory (WL), and in surface and underground boreholes at the Underground Research Laboratory (URL). Based on these investigations domains of low permeability, sparsely fractured rock (SFR) have been identified in the Lac du Bonnet batholith

    The incidence of group C and G Streptococcus (GCGS) bacteremia, which is associated with severe disease and death, is increasing. We characterized clinical features, outcomes, and genetic determinants of GCGS bacteremia for 89 patients in Winnipeg, Manitoba, Canada, who had GCGS bacteremia during 2012-2014. Of the 89 patients, 51% had bacteremia from skin and soft tissue, 70% had severe disease features, and 20% died. Whole-genome sequencing analysis was performed on isolates derived from 89 blood samples and 33 respiratory sample controls: 5 closely related genetic lineages were identified as being more likely to cause invasive disease than non-clade isolates (83% vs. 57%, p = 0.002). Virulence factors cbp, fbp, speG, sicG, gfbA, and bca clustered clonally into these clades. A clonal distribution of virulence factors may account for severe and fatal cases of bacteremia caused by invasive GCGS.

    Full Text Available Traits that converge in appearance under similar environmental conditions among phylogenetically independent lineages are thought to represent adaptations to local environments. We tested for convergence in nest morphology and composition of birds breeding in two ecologically different locations in Canada: Churchill in northern Manitoba and Elgin in southeastern Ontario. We examined nests from four families of passerine birds (Turdidae: Turdus, Parulidae: Dendroica, Emberizidae: Passerculus and Fringillidae: Carduelis where closely related populations or species breed in both locations. Nests of American Robins, Yellow Warblers, and Carduelis finches had heavier nest masses, and tended to have thicker nest-walls, in northern Manitoba compared with conspecifics or congenerics breeding in southeastern Ontario. Together, all species showed evidence for wider internal and external nest-cup diameters in northern Manitoba, while individual species showed varying patterns for internal nest-cup and external nest depths. American Robins, Yellow Warblers, and Carduelis finches in northern Manitoba achieved heavier nest masses in different ways. American Robins increased all materials in similar proportions, and Yellow Warblers and Common Redpolls used greater amounts of select materials. While changes in nest composition vary uniquely for each species, the pattern of larger nests in northern Manitoba compared to southeastern Ontario in three of our four phylogenetically-independent comparisons suggests that birds are adapting to similar selective pressures between locations.

    First Nations people are descendants of Canada's original inhabitants. In consequence of historical and ongoing structural injustices, many First Nations families struggle with challenging living conditions, including high rates of poverty, poor housing conditions, mental illness and social isolation. These risk factors impede caregivers' abilities to meet their children's basic physical and psychosocial needs. Home visiting programmes were developed to support child developmental health in families facing parenting challenges. However, whether home visiting is an effective intervention for First Nations families has not been examined. We are evaluating two home visiting programmes in Manitoba, Canada, to determine whether they promote nurturing family environments for First Nations children. This research builds on new and established relationships among academic researchers, government decision-makers and First Nations stakeholders. We will link health, education and social services data from the Manitoba Population Research Data Repository to data from two home visiting programmes in Manitoba. Logistic regression modelling will be used to assess whether programme participation is associated with improved child developmental health, better connections between families and social services, reduced instances of child maltreatment and being taken into out-of-home care by child welfare and reduced inequities for First Nations families. Non-participating individuals with similar sociodemographic characteristics will serve as comparators. We will use an interrupted time series approach to test for differences in outcomes before and after programme implementation and a propensity score analysis to compare differences between participants and non-participants. Approvals were granted by the Health Information Research Governance Committee of the First Nations Health and Social Secretariat of Manitoba and the University of Manitoba Health Research Ethics Board.

    Accelerator mass spectrometry and conventional radiocarbon age determinations of organic matter from paleosols indicate that the Brandon Sand Hills area of southern Manitoba has been subjected to recurrent intervals of eolian activity in the past 5000 years. Although precise regional correlations are precluded by dating uncertainties, periods of most notable paleosol development occurred around 2300 to 2000, 1400 to 1000, and 600 to 500 cal yr BP with eolian activity occurring before and after each of these periods. Episodes of eolian activity may correspond to periods of regional drought, whereas paleosols mark periods of increased moisture availability and stabilization by vegetation. The geochemistry of the eolian sands, paleosols and source sediments indicates that partial leaching of carbonates occurs from pedogenesis during humid climatic phases, and that this is probably the primary mechanism of carbonate depletion of eolian sands in this area. Recent trends in sand dune activity from historic aerial photography and early explorers' accounts indicate that the few active dunes that presently exist have stabilized at a rate of 10-20% per decade, despite several severe droughts in the 20th century. This may be attributed to pre-settlement droughts that were more severe than those in historic times although regional dune stabilization may also be related, in part, to the spread of forest cover in the past few hundred years.

    2002-01-01

    In the Red River region of southern Manitoba, Canada, the frequency of flood events tends to increase during cooler and wetter climate conditions. Predictably, recorded Red River flood stages are primarily a result of meteorological conditions which produce an increase runoff due to excess snowmelt and heavy spring precipitation. Winter skewed precipitation periods corresponding to cooler and wetter conditions in the Red River Basin may provide traceable oxygen isotope signals in hydrologically sensitive trees occupying the basin. To test this hypothesis, three overlapping oak tree-ring chronologies (KPO1: 1990 to 1795; STVO1: 1985 to 1797; STVO2: 1990 to 1845) were annually sampled and processed for their cellulose

    In November 2010, an outbreak of avian influenza (AI) due to the H5N2 subtype virus occurred in a turkey breeder farm in northern Manitoba, Canada. The only clinical signs observed were depression, decrease in food consumption, and loss of egg production. The hemagglutinin (HA) cleavage (HA(0)) site of the isolated H5N2 virus was PQRETR/GLF, consistent with low pathogenic AI viruses. The intravenous pathogenicity index of this virus was zero. Whole-genome sequencing of two isolates that originated from two different barns was performed, and both isolates had 100% identical protein sequence in PB2, HA, NP, M1, M2, NS1, and NS2. The remaining gene segments (PB1, PA, and NA) had a single amino-acid difference when compared with each other. The nucleotide and protein sequences of eight gene segments from both isolates showed 99 or greater identity with other AI viruses that have been circulating in free-living aquatic birds in Canada and the United States within the last 10 yr. Phylogenetic analysis of the HA and neuraminidase (NA) gene segments showed that these viruses are closely related to other H5 strains that have been isolated from Manitoba and other parts of Canada. Serologic testing of archived serum samples collected from these turkeys a week before the outbreak showed no evidence of AI infection. In addition, other farms that were located within 3 km radius from the infected farm and farms that had epidemiologic connection with the farm also tested negative for the presence of H5N2 AI virus or antibody. This indicates that the virus might have been introduced to the farm from wild aquatic birds only a short time before detection. Results of this study highlight the importance of early detection and the significance of ongoing Canada-wide surveillance of AI in domestic poultry as well as in wild aquatic birds/ducks.

    Full Text Available Abstract Background Métis are descendants of early 17th century relationships between North American Indians and Europeans. This study's objectives were: (1 to compare the health status of the Métis people to all other residents of Manitoba, Canada; and (2 to analyze factors in predicting the likelihood of diabetes and related lower limb amputation. Methods Using de-identified administrative databases plus the Métis Population Database housed at the Manitoba Centre for Health Policy, age/sex-adjusted rates of mortality and disease were calculated for Métis (n = 73,016 and all other Manitobans (n = 1,104,672. Diseases included: hypertension, arthritis, diabetes, ischemic heart disease (age 19+; osteoporosis (age 50+; acute myocardial infarction (AMI and stroke (age 40+; total respiratory morbidity (TRM, all ages. Using logistic regression, predictors of diabetes (2004/05-2006/07 and diabetes-related lower-limb amputations (2002/03-2006/07 were analyzed. Results Disease rates were higher for Métis compared to all others: premature mortality before age 75 (4.0 vs. 3.3 per 1000, p Conclusion Despite universal healthcare, Métis' illness and mortality rates are mostly higher. Although elevated diabetes risk persists for the Métis even after adjusting for sociodemographic, healthcare and comorbidity variables, the risk of amputation for Métis appears more related to healthcare access rather than ethnicity.

    Full Text Available We previously studied the association between fish consumption and prevalence of type 2 diabetes (T2D in Manitoba and Ontario First Nations (FNs, Canada and found different results. In this study, we used a difference in difference model to analyze the data. Dietary and health data from the First Nations Food Nutrition and Environment Study, a cross-sectional study of 706 Manitoba and 1429 Ontario FNs were analyzed. The consumption of fish was estimated using a food frequency questionnaire. Fish samples were analyzed for dichloro diphenyldichloro ethylene (DDE and polychlorinated biphenyls (PCBs content. Difference in difference model results showed that persistent organic pollutant (POP exposure was positively associated with T2D in a dose-response manner. Stronger positive associations were found among females (OR = 14.96 (3.72–60.11 than in males (OR = 2.85 (1.14–8.04. The breakpoints for DDE and PCB intake were 2.11 ng/kg/day and 1.47 ng/kg/day, respectively. Each further 1 ng/kg/day increase in DDE and PCB intake increased the risk of T2D with ORs 2.29 (1.26–4.17 and 1.44 (1.09–1.89, respectively. Our findings suggest that the balance of risk and benefits associated with fish consumption is highly dependent on the regional POP concentrations in fish.

    This Addendum to the Final Environmental Assessment for the Proposed Amendment to Presidential Permit PP-63 and Associated Modifications to 500 kV International Transmission Line: Forbes, Minnesota to Manitoba, Canada (DOE/EA-587) addresses Northern States Power Company's (NSP) proposed expansion of the Forbes Substation. The applicant has requested that the expansion take place on the west side of the substation, within the existing property line, instead of on the north side as originally proposed. All of the proposed construction would take place on property already owned by NSP. DOE has reviewed the environmental impacts associated with this minor modification and has determined that the conclusions reached in the environmental assessment and Finding of No Significant Impact prepared in connection with NSP's original amendment request remain valid

    A network of winter roads in northern Canada connects a number of remote First Nations communities to all-season roads and rails. The extent of the winter road networks depends on the geographic features, socio-economic activities, and the numbers of remote First Nations so that it differs among the provinces. The most extensive winter road networks below the 60th parallel south are located in Ontario and Manitoba, serving 32 and 18 communities respectively. In recent years, a warmer climate has resulted in a shorter winter road season and an increase in unreliable road conditions; thus, limiting access among remote communities. This study focused on examining the future freezing degree-days (FDDs) accumulations during the winter road season at selected locations throughout Ontario's Far North and northern Manitoba using recent climate model projections from the multi-model ensembles of General Circulation Models (GCMs) under the Representative Concentration Pathway (RCP) scenarios. First, the non-parametric Mann-Kendall correlation test and the Theil-Sen method were used to identify any statistically significant trends between FDDs and time for the base period (1981-2010). Second, future climate scenarios are developed for the study areas using statistical downscaling methods. This study also examined the lowest threshold of FDDs during the winter road construction in a future period. Our previous study established the lowest threshold of 380 FDDs, which derived from the relationship between the FDDs and the opening dates of James Bay Winter Road near the Hudson-James Bay coast. Thus, this study applied the threshold measure as a conservative estimate of the minimum threshold of FDDs to examine the effects of climate change on the winter road construction period.

    Results from clinical trials in the 1990s led to changes in the recommended treatment for the standard therapy for stage IIB-IVA cervical cancer from radiotherapy alone to chemo-radiotherapy. We conducted the first population-based study in Canada to investigate temporal treatment patterns for cervical cancer and long-term survival in relation to these changes in the treatment guidelines. Detailed information on stage and treatment for 1085 patients diagnosed with cervical cancer in 1984–2008 and identified from the population-based Manitoba Cancer Registry (MCR) in Canada was obtained from clinical chart review and the MCR. Factors associated with receiving guideline treatment were identified using logistic regression. All cause and cervical cancer specific survival were compared in patients who were and were not treated as recommended in the guidelines, using Cox proportional hazards models. The median follow-up time was 6.4 years (range: 0.05–26.5 years). The proportion of women who received guideline treatment was 79 % (95 % confidence interval [CI]: 76–81 %). However, the likelihood of being treated according to the guidelines over time was modified by age (p < 0.0001) and tumour stage at diagnosis (p = 0.002). Women who were treated according to the guidelines after the change in recommended clinical practice (1999–2008) had a significantly lower risk of death from all causes and from cervical cancer. This was driven by lower mortality rates in cases with stage IIB-IVA tumours (all causes of death: hazard ratio [HR] = 0.60, 95 % CI: 0.43–0.82, p = 0.002; cervical cancer related death: HR = 0.64, 95 % CI: 0.44–0.93, p = 0.02). The management of cervical cancer patients in Manitoba, Canada was in good agreement with treatment guidelines although reasons for departure from the guideline recommendations could not be examined further due to lack of data.

    Indigenous peoples (First Nations, Inuit, and Métis) are currently overrepresented in the HIV epidemic in Canada and are infected at a younger age than those who are not Indigenous. This article presents our findings on the stigma and discrimination (as well as related themes such as disclosure) experienced by Indigenous people who contracted HIV in their youth and live in urban and non-urban settings in Manitoba, Canada. The findings were derived from a qualitative study that sought to understand the experiences and needs of Indigenous people living with HIV (including AIDS). We situate such experiences within a social ecological framework towards developing a better structural understanding of the impacts of stigma and discrimination on the lives of Indigenous people who are HIV positive. Stigma and discrimination caused barriers for Indigenous people living with HIV through inhibiting their ease of access to supports including family, peers, community, and long- and short-term health services. Creative forms of outreach and education that are culturally appropriate and/or rooted in culture were considered to be possibly impactful ways of reducing stigma and discrimination at the community level. Learning from communities who are successfully managing stigma also showed promise for developing new programming. Copyright © 2017 Elsevier Ltd. All rights reserved.

  10. Lesion Distribution and Epidemiology of Mycobacterium bovis in Elk and White-Tailed Deer in South-Western Manitoba, Canada

    Full Text Available Surveillance for Mycobacterium bovis in free-ranging elk (Cervus elaphus and white-tailed deer (Odocoileus virginianus from south-western Manitoba was carried out from 1997 to 2010 to describe the lesions, epidemiology, and geographic distribution of disease. Tissues were cultured from animals killed by hunters, culled for management, blood-tested, or found opportunistically. Period prevalence in elk was approximately six times higher than deer, suggesting a significant reservoir role for elk, but that infected deer may also be involved. Prevalence was consistently higher in elk compared to deer in a small core area and prevalence declines since 2003 are likely due to a combination of management factors instituted during that time. Older age classes and animals sampled from the core area were at significantly higher risk of being culture positive. Positive elk and deer were more likely to be found through blood testing, opportunistic surveillance, and culling compared to hunting. No non-lesioned, culture-positive elk were detected in this study compared to previous studies in red deer.

  11. Sedimentary Records of Hyperpycnal Flows and the Influence of River Damming on Sediment Dynamics of Estuaries: Examples from the Nelson, Churchill, Moisie and Sainte-Marguerite Rivers (Canada)

    Sediment cores were sampled in the estuary of the Nelson and Churchill Rivers in western Hudson Bay, as well as in the estuary of the Moisie and Sainte-Marguerite Rivers in Gulf of St. Lawrence in order to evaluate the impact of hydroelectric dams on the sedimentary regime of these estuaries. The gravity cores at the mouth of the Nelson River recorded several cm-thick rapidly deposited layers with a reverse to normal grading sequence, indicating the occurrence of hyperpycnal flows generated by major floods during the last few centuries. These hyperpycnal flows were probably caused by ice-jam formation, which can increase both the flow and the sediment concentration following the breaching of such natural dams. Following the construction of hydroelectric dams since the 1960s, the regulation of river discharge prevented the formation of hyperpycnal flows, and hence the deposition of hyperpycnites in the upper part of the cores. In the core sampled in the estuary of the Churchill River, only one hyperpycnite was recorded. This lower frequency may be due to the enclosed estuary of the Churchill River, its weaker discharge and the more distal location of the coring site.In the Gulf of St. Lawrence, grain size measurements allowed the identification of a major flood around AD 1844±4 years in box cores from both the Sainte-Marguerite and Moisie Rivers, whereas a drastic decrease in variations in the median grain size occurred around AD ~1900 in the estuary of the Sainte-Marguerite River, highlighting the offshore impact of the SM1 dam construction in the early 1900s. Furthermore, sedimentological variations in the box cores from both estuaries have been investigated by wavelet analysis and the sharp disappearance of high frequencies around AD 1900 in the estuary of the dammed river (Sainte-Marguerite River), but not in the estuary of the natural river (Moisie River), also provides evidence of the influence of dams on the sedimentary regime of estuaries.

    Climate warming may increase the size and frequency of fires in the boreal biome, possibly causing greater carbon release that amplifies warming. However, in peatlands, vegetation change may also control long-term fire and carbon accumulation, confounding simple relationships between climate, fire, and carbon accumulation. Using 17 peat cores dating to 8000 cal years B.P. from northern Manitoba, Canada, we addressed the following questions: (1) Do past climate changes correlate with shifts in peatland vegetation? (2) What is the relationship between peatland vegetation and fire severity? (3) What is the mean return interval for boreal peat fires, and how does it change across fires of different severities? (4) How does fire severity affect carbon accumulation rates? (5) Do fire and long-term carbon accumulation change directly in response to climate or indirectly though climate-driven changes in vegetation? We measured carbon accumulation rates, fire severity, and return intervals using macroscopic charcoal and changes in vegetation using macrofossils. Climate and vegetation changes covaried, with shifts from wetter fen to drier, forested bog communities during the Holocene Thermal Maximum (HTM). Fires became more severe following the shift to forested bogs, with fire severity peaking after 4000 cal years B.P. rather than during the HTM. Rising fire severity, in turn, was correlated with a significant decrease in carbon accumulation from ˜6000 to 2000 cal years B.P. The Medieval Warm Period and Little Ice Age affected vegetation composition and permafrost, further impacting fire and carbon accumulation. Our results indicate that long-term changes in fire and carbon dynamics are mediated by climate-driven changes in vegetation.

    Full Text Available From the early 1930s until his peace time premiership (1951-1955, Winston Churchill was one of the strongest advocates of the concept of a United Europe. While this is well known among scholars of 20th century British history, Churchill’s actual vision for what a United Europe might look like has received less attention. Still less attention has been paid to Churchill’s opinions of the roles other nations might play within the new Europe. This article will examine Churchill’s view of Turkey in the new European order and will reveal that Churchill saw Turkey as a part of, (or at least an extension of Europe. However, this article will also reveal that Churchill’s conceptualisation of Turkey’s role was largely predicated on 19th century geostrategic thinking.

    End-stage renal disease (ESRD) is a major public health problem with increasing prevalence and costs. An understanding of the long-term trends in dialysis rates and outcomes can help inform health policy. We determined the optimal case definition for the diagnosis of ESRD using administrative claims data in the province of Manitoba over a 7-year period. We determined the sensitivity, specificity, predictive value and overall accuracy of 4 administrative case definitions for the diagnosis of ESRD requiring chronic dialysis over different time horizons from Jan. 1, 2004, to Mar. 31, 2011. The Manitoba Renal Program Database served as the gold standard for confirming dialysis status. During the study period, 2562 patients were registered as recipients of chronic dialysis in the Manitoba Renal Program Database. Over a 1-year period (2010), the optimal case definition was any 2 claims for outpatient dialysis, and it was 74.6% sensitive (95% confidence interval [CI] 72.3%-76.9%) and 94.4% specific (95% CI 93.6%-95.2%) for the diagnosis of ESRD. In contrast, a case definition of at least 2 claims for dialysis treatment more than 90 days apart was 64.8% sensitive (95% CI 62.2%-67.3%) and 97.1% specific (95% CI 96.5%-97.7%). Extending the period to 5 years greatly improved sensitivity for all case definitions, with minimal change to specificity; for example, for the optimal case definition of any 2 claims for dialysis treatment, sensitivity increased to 86.0% (95% CI 84.7%-87.4%) at 5 years. Accurate case definitions for the diagnosis of ESRD requiring dialysis can be derived from administrative claims data. The optimal definition required any 2 claims for outpatient dialysis. Extending the claims period to 5 years greatly improved sensitivity with minimal effects on specificity for all case definitions.

    A modeling technique using spherical shell elements and equivalent dipole sources has been applied to Magsat signatures at the Churchill-Superior boundary in Manitoba, Ontario, and Ungava. A large satellite magnetic anomaly (12 nT amplitude) on POGO and Magsat maps near the Churchill-Superior boundary was found to be related to the Richmond Gulf aulacogen. The averaged crustal magnetization in the source region is 5.2 A/m. Stacking of the magnetic traces from Magsat passes reveals a magnetic signature (10 nT amplitude) at the Churchill-Superior boundary in an area studied between 80 deg W and 98 deg W. Modeling suggests a steplike thickening of the crust on the Churchill side of the boundary in a layer with a magnetization of 5 A/m. Signatures on aeromagnetic maps are also found in the source areas for both of these satellite anomalies.

    There is uncertainty surrounding the duration, magnitude and frequency of historical hydroclimatic extremes such as hydrologic droughts and floods prior to the observed record. In regions where paleoclimatic studies are less reliable, Global Climate Models (GCMs) can provide useful information about past hydroclimatic conditions. This study evaluates the use of Coupled Model Intercomparison Project 5 (CMIP5) GCMs to enhance the understanding of historical droughts and floods across the Canadian Prairie region in the Nelson-Churchill Watershed (NCW). The NCW is approximately 1.4 million km2 in size and drains into Hudson Bay in Northern Manitoba, Canada. One hundred years of observed hydrologic records show extended dry and wet periods in this region; however paleoclimatic studies suggest that longer, more severe droughts have occurred in the past. In Manitoba, where hydropower is the primary source of electricity, droughts are of particular interest as they are important for future resource planning. Twenty-three GCMs with daily runoff are evaluated using 16 metrics for skill in reproducing historic annual runoff patterns. A common 56-year historic period of 1950-2005 is used for this evaluation to capture wet and dry periods. GCM runoff is then routed at a grid resolution of 0.25° using the WATFLOOD hydrological model storage-routing algorithm to develop streamflow scenarios. Reservoir operation is naturalized and a consistent temperature scenario is used to determine ice-on and ice-off conditions. These streamflow simulations are compared with the historic record to remove bias using quantile mapping of empirical distribution functions. GCM runoff data from pre-industrial and future projection experiments are also bias corrected to obtain extended streamflow simulations. GCM streamflow simulations of more than 650 years include a stationary (pre-industrial) period and future periods forced by radiative forcing scenarios. Quantile mapping adjusts for magnitude

    Lake sediments are valuable archives of atmospheric metal deposition, but the stability of some element profiles may possibly be affected by diagenetic changes over time. In this extensive case study, the stability of sedimentary Cd, Cu, Hg, Pb and Zn profiles was assessed in dated sediment cores that were collected in 2004 from four smelter-affected lakes near Flin Flon, Manitoba, which had previously been cored in 1985. Metal profiles determined in 1985 were in most cases clearly reproduced in the corresponding sediment layers in 2004, although small-scale spatial heterogeneity in metal distribution complicated the temporal comparisons. Pre-smelter (i.e. pre-1930) increases in metal profiles were likely the result of long-range atmospheric metal pollution, coupled with particle mixing at the 1930s sediment surface. However, the close agreement between key inflection points in the metal profiles sampled two decades apart suggests that metals in most of the lakes, and Hg and Zn in the most contaminated lake (Meridian), were stable once the sediments were buried below the surface mixed layer. Cadmium, Cu and Pb profiles in Meridian Lake did not agree as well between studies, showing evidence of upward remobilization over time. Profiles of redox-indicator elements (Fe, Mn, Mo and U) suggested that the rate of Mn oxyhydroxide recycling within sediment was more rapid in Meridian Lake, which may have caused the Cd, Cu and Pb redistribution. - Highlights: • Sedimentary Cd, Cu, Hg, Pb and Zn profiles in four lakes were mostly unchanged over 19 years. • In one lake, Cd, Cu and Pb profiles were offset relative to the originals. • The offset could indicate diagenetic upcore dispersal of these metals.

  7. Modernization in the Manitoba north: The housing initiative

    1993-01-01

    Responding to the perceived community needs of the native population, the Canadian federal and provincial governments have implemented a series of programs intended to address the issues of community well-being, a central feature of which was the modernization of native communities. In Manitoba, the best examples of this modernization initiative are associated with the hydroelectric power projects in northern Manitoba. The modernization program following Manitoba Hydro's Churchill-Nelson River Hydro-Electric Project is described, focusing on the housing component of the process in the communities of Chemawawin, South Indian Lake, Cross Lake, Nelson House, Norway House, Split Lake, and York Landing. In these communities, the modernization process can be considered as a hydro-induced program of redevelopment. In each case, the community was forced to accept the consequences of Manitoba Hydro's development plan. From the flooding of traplines to the relocation of total settlements, the hydro operation has drastically altered the traditional way of life in the selected communities. Although the hydro developments have had a limited short-term positive impact (i.e. provision of employment or training), the impact has been generally negative. The case can be made that the housing component of the program has never clearly recognized the unique quality of native culture nor specific community needs. New housing, often the first priority in all seven communities studied, was too often neglected in favor of housing services. When new housing was made available, site development was geared to demands of modern servicing as opposed to the actual needs of local residents. 34 refs., 1 fig., 11 tabs

    Uranium series disequilibrium measurements of actinide activities and activity ratios have been used to study the geochemical history of Lac du Bonnet granite, from the URL site, Pinawa, Canada. Measurements on core profiles between fractured surfaces and the parent rock show that the granite underwent high temperature events several million years ago, followed by more recent low temperature events within the last million years. The main locations for the rock/water interaction and exchange of actinides are the fracture surfaces. The results of similar measurements on separated mineral phases show that the 'soft' minerals such as biotite and feldspar are more vulnerable to weathering than the 'hard' accessory minerals such as zircon.

    Alfalfa is a highly outcrossing perennial species that can be noticed in roadsides as feral populations. There remains little information available on the extent of feral alfalfa populations in western Canadian prairies and their role in gene flow. The main objectives of this study were (a) to document the occurrence of feral alfalfa populations, and (b) to estimate the levels of outcrossing facilitated by feral populations. A roadside survey confirmed widespread occurrence of feral alfalfa populations, particularly in alfalfa growing regions. The feral populations were dynamic and their frequency ranged from 0.2 to 1.7 populations km(-1). In many cases, the nearest feral alfalfa population from alfalfa production field was located within a distance sufficient for outcrossing in alfalfa. The gene flow study confirmed that genes can move back and forth between feral and cultivated alfalfa populations. In this study, the estimated outcrossing levels were 62% (seed fields to feral), 78% (feral to seed fields), 82% (hay fields to feral) and 85% (feral to feral). Overall, the results show that feral alfalfa plants are prevalent in alfalfa producing regions in western Canada and they can serve as bridges for gene flow at landscape level. Management of feral populations should be considered, if gene flow is a concern. Emphasis on preventing seed spill/escapes and intentional roadside planting of alfalfa cultivars will be particularly helpful. Further, realistic and pragmatic threshold levels should be established for markets sensitive to the presence of GE traits.

  12. Limnological regime shifts caused by climate warming and Lesser Snow Goose population expansion in the western Hudson Bay Lowlands (Manitoba, Canada).

    Shallow lakes are dominant features in subarctic and Arctic landscapes and are responsive to multiple stressors, which can lead to rapid changes in limnological regimes with consequences for aquatic resources. We address this theme in the coastal tundra region of Wapusk National Park, western Hudson Bay Lowlands (Canada), where climate has warmed during the past century and the Lesser Snow Goose (LSG; Chen caerulescens caerulescens) population has grown rapidly during the past ∽40 years. Integration of limnological and paleolimnological analyses documents profound responses of productivity, nutrient cycling, and aquatic habitat to warming at three ponds ("WAP 12", "WAP 20", and "WAP 21″), and to LSG disturbance at the two ponds located in an active nesting area (WAP 20, WAP 21). Based on multiparameter analysis of (210)Pb-dated sediment records from all three ponds, a regime shift occurred between 1875 and 1900 CE marked by a transition from low productivity, turbid, and nutrient-poor conditions of the Little Ice Age to conditions of higher productivity, lower nitrogen availability, and the development of benthic biofilm habitat as a result of climate warming. Beginning in the mid-1970s, sediment records from WAP 20 and WAP 21 reveal a second regime shift characterized by accelerated productivity and increased nitrogen availability. Coupled with 3 years of limnological data, results suggest that increased productivity at WAP 20 and WAP 21 led to atmospheric CO2 invasion to meet algal photosynthetic demand. This limnological regime shift is attributed to an increase in the supply of catchment-derived nutrients from the arrival of LSG and their subsequent disturbance to the landscape. Collectively, findings discriminate the consequences of warming and LSG disturbance on tundra ponds from which we identify a suite of sensitive limnological and paleolimnological measures that can be utilized to inform aquatic ecosystem monitoring.

    The procedures for the investigation and characterization of contaminated sites in Manitoba are described in an effort to provide a baseline for developing applicable risk-based remedial action and management plans. This document presents information regarding the methods and protocols for sites where the quality of groundwater, surface water, sediments or soil may have been affected by pollutants as a result of past or present usage of the site. The 1998 document focuses on petroleum impacted sites and also includes the requirements for the investigation of sites potentially impacted by other pollutants. It is based on the principles established by the Canadian Council of Ministers of the Environment for the management of sites in Canada and the requirements of the Manitoba Contaminated Sites Remediation and Consequential Amendments Act. Manitoba's petroleum storage program and the hazardous waste management program, including the disposal or treatment of contaminated soils are also summarized

  17. Gender, politics, and regionalism: factors in the evolution of registered psychiatric nursing in Manitoba, 1920-1960.

    2011-01-01

    In Canada, psychiatric nursing care is provided by two kinds of nurses. East of Manitoba, it is provided by registered nurses who may or may not have specialized psychiatric nursing education. In the four western provinces, a distinct professional group, registered psychiatric nurses, also provide care. Saskatchewan was the first province to achieve distinct legislation, in 1948, followed by British Columbia in 1951, Alberta in 1955, and Manitoba in 1960. Several factors coalesced to sway Manitoba to adopt the distinct profession model. First, there was little interest by the general nursing body in mental hospital nursing. Second, the other three western provinces had formed a Canadian Council of Psychiatric Nursing that encouraged mental hospital attendants and nurses in Manitoba. Third, a group of male attendants took on leadership roles supported by the mental hospital superintendents. Finally, Manitoba was culturally and geographically more aligned with western than eastern Canada.

  18. Sea Level, Land Motion, and the Anomalous Tide at Churchill, Hudson Bay

    2015-12-01

    The importance of the tide gauge at Churchill, Manitoba, cannot be overstated. It is the only permanently operating tide gauge in the central Canadian Arctic, and it sits on a prime spot for monitoring the mantle's rebound from the Laurentide ice loss. Yet interpretation of the sea-level time series at Churchill has long been problematic, going back even to early work by Gutenberg in the 1940s. The long-term relative sea-level rates are inconsistent: approximately -4, -19, -5 ± 1 mm/y for the periods 1940-1970, 1970-1990, 1990-2014 respectively. Annual mean high water (MHW) and mean low water (MLW) reflect these trends until around 1990, after which MLW leveled off and is now nearly unchanging. Slightly later, around 2000, the semidiurnal tides became very anomalous, with falling amplitudes and slightly increasing phase lags. The amplitude of M2 was approximately 154 cm before 2000; it dropped to about 146 cm by 2010 and reached an all-time low of 142 cm in 2014. Satellite altimeter estimates of the tide in this region, although challenging because of seasonal ice cover, show no comparable M2 changes, so the tidal changes must be localized to the near vicinity of the gauge (or to the gauge itself if caused by a malfunction). On the other hand, altimetry confirms the post-1992 Churchill measurements of mean sea level, thanks to the long time series of land motion measurements obtained at GPS station CHUR, which gives a vertical uplift of 10.1 mm/y. Combining satellite altimeter data with the Churchill tide-gauge data gives an implied vertical crustal rate of about 9.0 ± 0.8 mm/y, in reasonable agreement with the GPS. In summary, we have still anomalous MSL measurements at the Churchill gauge for the intermediate 1970-1990 era, and very anomalous tidal measurements since 2000, but we have apparently quite reliable MSL rates since 1990.

    Several drowning fatalities and safety incidents have occurred around dams in Ontario, Manitoba and other jurisdictions in Canada. Following these incidents, Manitoba Hydro implemented several measures to improve public safety around its dams with the development of a warning signs manual. Manitoba Hydro found that a standard centralized approach to the process of improving public safety is better for ensuring compliance and consistency, even though they have safety measures in place. This paper described the process that Manitoba Hydro has followed in developing a formal set of public water safety around dams (PWSD) guidelines and a program for implementing these guidelines. This program was developed with the intent of providing a high standard of public protection and continuous improvement and monitoring on par with the effect spent on similar dam safety type programs. This paper focused on the development of the pilot PWSD management plan for Pine Falls generating station in order to test the effectiveness and usability of the guidelines.

  3. Greenhouse gas emissions related to landscape elements in the subarctic environment at Churchill, Manitoba

    2006-01-01

    The relationship between greenhouse gas (GHG) emissions, landscape elements and major environmental regulators was studied. The hydrologic regimes of the Hudson Bay Lowlands are expected to change along with the extent of permafrost and composition of vegetation due to increased levels of GHGs associated with global warming. Two transects were created at a Polygonized-Peat Plateau (PPP) and a Spruce Forest (SF) site in 2005. A sub-set on 4 dominant landscape elements of each transect were used to estimate emissions of carbon dioxide (CO 2 ), methane (CH 4 ), and nitric oxide (N 2 O) on a weekly basis from June to August. In order to obtain a good sampling representation of environmental conditions and of the gradients in plant communities, the entire transect at PPP was sampled monthly. In order to examine the role of soil conditions on the production and consumption of GHG leading to surface fluxes, soil gas samplers were installed at 2 depths at both sites. N 2 O production and consumption were found to be inconsequential at both sites. However, high methane emissions were observed when the volumetric moisture content (VMC) rose higher than 80 per cent at the edge of the ponds. Methane consumption was found to be related to low VMC values (20-40 per cent) for the tops of peat polygons. Soil atmosphere concentrations for CO 2 and CH 4 at PPP were typically much higher at depths of 23-32 cm compared to depths of 5-9 cm. Some of the wettest landscape elements had very high CH 4 content, but had no corresponding CH 4 flux from the soil surface, suggesting that the gas was consumed under aerobic conditions at the soil surface. It was concluded that GHG emissions from both sites were altered by both landscape elements and environmental regulators such as temperature and moisture. Future work will focus on identifying the association of these relationships to processes responsible for GHG emissions in subarctic environments. The impact of global warming on these emissions will also be examined

    We have made simultaneous measurements of fluxes of He an heavy nuclei (Z< or =10) in primary cosmic rays at three levels of solar activity. These nuclei have been studied in three nuclear emulsion stacks exposed over Fort Churchill, Canada, in 1963, 1964, and 1967. We had earlier reported our results on the heavy nuclei at the Hobart conference (Bhatia et al., 1971). Experimental results based on 1514 He nuclei tracks that were measured in these three stacks are presented in this paper. The experimentally obtained He and heavy nuclei differential energy spectra have been compared with the theoretically calculated near-earth spectra

    1975-01-01

    The Echo 2 rocket flight launched from Fort Churchill, Manitoba, offered the opportunity to observe high-latitude low-level electron precipitation during quiet magnetic conditions. Although no visual aurora was evident at the time of the flight, an auroral spectrum sharply peaked at a few keV was observed to have intensities from 1 to 2 orders of magnitude lower than peaked spectra typically assoicated with bright auroral forms. There is a growing body of evidence that relates peaked electron spectra to discrete aurora. The Echo 2 observations show that whatever the mechanism for peaking the electron spectrum in and above discrete forms, it operates over a range of precipitation intensities covering nearly 3 orders of magnitude down to subvisual or near subvisual events

    1991-01-01

    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

    In an annual survey of Manitoba's petroleum industry, data are presented on oil and natural gas leases and sales, geophysical activity, exploration and drilling activity, production, exports to other provinces and the USA, oil prices and sales value, royalties and taxes, direct revenues from oil exploration and development, reserves, industry expenditures, and oil fields. Throughout the report, explainations are given of the items covered. Descriptions are made of new developments, the oil market, oil policies, incentive programs, and industrial activities. During 1991, 54 wells were drilled, compared to 79 in 1990. Oil production was down ca 3% from 1990 levels, to 712,792 m 3 , the value of the oil produced decreased 21% to ca $90.3 million, and provincial revenues from the oil industry declined by 15%. Oil industry expenditures in the province were estimated at $69 million, down 9% from 1990. As of the end of 1991, there were 11 oil fields and 118 non-confidential oil pools designated in Manitoba. The forecast for 1992 indicates that exploration activity will increase in response to new incentive programs. Crude oil production is expected to decline slightly to about 667,000 m 3 . 9 figs., 17 tabs

  19. Presentation to the Manitoba ethanol advisory panel

    International Nuclear Information System (INIS)

    2002-01-01

    The Manitoba Chambers of Commerce, representing the entire spectrum of businesses from all regions of Manitoba, has long advocated for alternative fuels based on agricultural products. Some of the major questions that must be answered in this debate on the ethanol industry in Manitoba are: (1) What are the benefits of a vibrant ethanol industry? (2) What are the facts about ethanol, and are those facts getting out to the public? (3) and How do we foster a vibrant ethanol industry in Manitoba? This document places the emphasis on the third issue raised. The Manitoba Chambers of Commerce endorses the idea of a mandated blend of ethanol. It also believes that Manitoba should maintain its gasoline tax-gasohol preference. The Manitoba Chambers of Commerce recommends against the government controlling the size and number of ethanol facilities in the province. It also recommends that funding not be afforded to the creation of new programs designed for the specific purpose of providing financial assistance to the ethanol industry. Government awareness campaigns should be limited to issues within the public interest, dealing with environmental and consumer issues and benefits. The government should commit to the enhancement of the vitality of new generation cooperatives (NGCs) in Manitoba. Emphasis by the government should be placed on ensuring that the required infrastructure and partnerships are in place to foster the development and commercialization of innovations in this field. The Manitoba Chambers of Commerce recommended that the provincial government facilitate partnerships through the sponsoring of provincial conferences, while pursuing its partnership efforts with the federal and other provincial governments

    A survey was conducted to gather information regarding the history of land-use of the Innu Nation of Labrador. The survey was made possible through research into land use and documentary sources plus the analysis of geomorphologic features and air photos. The areas of the survey included portions of the Strait of Belle Isle, Churchill Valley, proposed transmission routes of the Churchill Power Project, and survey lines at Atikonak Lake. Over 65 historical and traditional land-use sites were recorded, including two major Hudson Bay Company fur-trading posts in the Churchill Valley. This survey will be important in helping to ensure that important sites are not destroyed as a result of the proposed Churchill Power Project

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

    The productive areas of Manitoba are located along the northeastern flank of the Williston basin. Rocks of Paleozoic, Mesozoic and Cenozoic age form a basin-ward thickening wedge of sedimentary strata that reach a total thickness of 2,300 m in the southwest corner of the province. A brief description is presented of the geology and reservoir characteristics of petroleum producing horizons in Manitoba. Manitoba's Crown land tenure system of leases and exploitation reservations is described and an overview of Manitoba's petroleum royalty and tax structure and incentive programs is presented. Exploration and development opportunities in Manitoba are outlined. There are numerous development drilling opportunities along the poorly defined edges of existing pools. Exploration opportunities exist in the Mississippian in the sparsely explored areas outside existing field boundaries. Deeper Devonian and Ordovician horizons, productive elsewhere in the Williston basin, remain relatively untested in Manitoba. An attractive, stable investment climate is created by: availability of land at comparatively low cost; a stable and competitive fiscal regime; incentive programs designed to enhance pay-out; low drilling density; relatively untested deep potential below the Mississippian; low drilling and completion costs; easy access to market; and competitive oil prices. 12 refs., 11 figs., 7 tabs

    This paper reports that the Canadian oil and natural gas sector is in for another grim year in 1992. Further streamlining to enhance operating efficiencies and control costs is the first order of the day. About $4 billion worth of producing properties remains on the market, as corporate focus continues to shift to core properties. New management structures put in place in the last two years will be severely tested to improve the sector's financial performance. Massive write-downs in 1990 and 1991 have put balance sheets in much better shape for improved financial performance in the future. Although new long-term debt exceeded redemptions in 1991, largely because of debt- financing of major capital projects, individually most companies are in better shape through significant debt repayment or restructuring. The substantial reductions in interest rates will also help to enhance discretionary cash flow. At this stage, everything appears to be in place to expect that 1992 will represent the bottom of the down-cycle for Canada

    1990-01-01

    A study was carried out to examine the potential effects of a doubled carbon dioxide climate change scenario on gross margins received from cropping enterprises and the patterns of crop production in Manitoba, Canada. The 1987 run of the Goddard Institute for Space Studies (GISS) general circulation model (GCM) was chosen to supply climatic data. Models were developed for yield changes in existing crops, crop migration, and economic impacts. Three scenarios were considered: scenario 1 using historical seeding dates and climates, scenario 2 using historical seeding dates and a flat 3 degree C temperature increase, and scenario 3 where seeding is advanced 14 days and temperatures increase by 3 degree C. The results suggest that climatic warming will have a beneficial effect on the cropping sector in Manitoba. Gross margins are 53% greater in scenario 2 and 190% greater in scenario 3 when the increased area of productive land is considered. Wider cultivation of higher value crops offsets the negative effect of decreased yields of other crops. The changed climate will favour the introduction of longer maturing varieties of existing crops, greater commerical production of existing crops such as sunflowers, soybeans and corn, and the introduction of totally new crops such as sorghum. 26 refs., 1 tab

    2003-08-01

    Full Text Available Abstract Background To describe the demographic and geographic distribution of tuberculosis (TB in Manitoba, thus determining risk factors associated with clustering and higher incidence rates in distinct subpopulations. Methods Data from the Manitoba TB Registry was compiled to generate a database on 855 patients with tuberculosis and their contacts from 1992–1999. Recovered isolates of M. tuberculosis were typed by IS6110 restriction fragment length polymorphisms. Bivariate and multivariate logistic regression models were used to identify risk factors involved in clustering. Results A trend to clustering was observed among the Canadian-born treaty Aboriginal subgroup in contrast to the foreign-born. The dominant type, designated fingerprint type 1, accounts for 25.8% of total cases and 75.3% of treaty Aboriginal cases. Among type 1 patients residing in urban areas, 98.9% lived in Winnipeg. In rural areas, 92.8% lived on Aboriginal reserves. Statistical models revealed that significant risk factors for acquiring clustered tuberculosis are gender, age, ethnic origin and residence. Those at increased risk are: males (p p p p Conclusion Molecular typing of isolates in conjunction with contact tracing data supports the notion of the largest ongoing transmission of a single strain of TB within the treaty-status population of Canada recorded to date. This data demonstrates the necessity of continued surveillance of countries with low prevalence of the disease in order to determine and target high-risk populations for concentrated prevention and control measures.

    1998-11-01

    Manitoba Hydro has four commitments: 1) they will integrate climate change management into their plans and operations, 2) between 1991 and 2012 they will reduce their greenhouse gas emissions in excess of 6% below 1990 levels, 3) they anticipate that their greenhouse gas production will be in excess of 40% below their 1990 levels by 2010-11, and 4) they have the potential to make a greater contribution to national and international environmental and economic efforts by developing additional hydroelectric energy. The performance to date in implementing their strategy since 1990 includes: the 1330 megawatt Limestone Generating Station came into full production in 1992, which has increased electricity output without additional greenhouse gas emissions; four coal fueled generating units were removed from service at Brandon Generating Station in 1996, reducing coal generating capacity; seven communities previously served have been connected to the province's provincial grid, reducing the emissions from diesel generators; demand-side energy initiatives resulted in a saving of 45 megawatts since 1990, and supply-side initiatives, 152 megawatts; and net exports have increased significantly, from 2,296 megawatt hours in 1990 to 13,888 megawatt hours in 1997-98, which displaces energy that would otherwise have been produced at fossil-fueled generating stations. tabs

  10. Winston Churchill And The European Union

    2015-06-01

    Full Text Available Given Winston Churchill’s influence and achievement as a writer, historian, adventurer, soldier, artist, and politician, his participation in the European integration process is crucial to understanding the entire scope of the project in its origins. Churchill was a fundamental voice promoting the Franco-British Union, a promoter of the European Communities, and an active participant of the Congress of Europe, embryo of the Council of Europe. This article analyzes Churchill’s view of European integration through his political speeches, in particular those delivered in Zurich and in The Hague, his ideas about the League of Nations and the United Nations, his understanding of the British Empire, and the special relations between the UK and the USA. His participation in the process of uniting Europe in its early stages provides us with essential information about the original plans for the creation of a united Europe and understanding the traditional British approach to the EU, including the current position of the conservative government led by Cameron.

    Details of new energy supply in Manitoba were presented with reference to Ontario's growing demand for security of supply. The Manitoba Clean Environment (CEC) released its report on the 200 MW Wuskwatim Hydro Generation and Transmission Projects. The CEC recommended that a licence under the Environment Act be released subject to various terms and conditions in the project licence. The approved Wuskwatim project also includes 350 km of 230 kV transmission lines. Details of the recently built Harvey-Glenboro 230 kV transmission line were presented. It was anticipated that Wuskwatim will help sustain exports at current levels as the Manitoba load grows. In 2002, 42 per cent of electricity revenue was from outside the province, and the province was number one by volume in exports to the United States in 1997. There is approximately 5000 MW of economically and environmentally developable hydro in Manitoba. Studies are currently underway for Conawapa, an undeveloped hydro site with the potential to generate 1250 MW. Potential transmission routes were outlined along with issues concerning transmission costs and impacts on reliability and security in Ontario. The benefits of a large hydro purchase from Manitoba were outlined. A chart of life-cycle greenhouse gas emissions was presented. It was suggested that large hydro can be a low impact renewable energy source. It was concluded that the Ontario Resource Adequacy Market rules should consider out of province capacity. tabs., figs

  13. Use of borehole-geophysical logs and hydrologic tests to characterize crystalline rock for nuclear-waste storage, Whiteshell Nuclear Research Establishment, Manitoba, and Chalk River Nuclear Laboratory, Ontario, Canada

    Davison, C.C.

    1982-12-01

    A number of borehole methods were used in the investigation of crystalline rocks at Whiteshell Nuclear Research Establishment and Chalk River Nuclear Laboratory in Canada. The selection of a crystalline-rock mass for the storage of nuclear waste likely will require the drilling and testing of a number of deep investigative boreholes in the rock mass. Although coring of at least one hole in each new area is essential, methods for making in-situ geophysical and hydrologic measurements can substitute for widespread coring and result in significant savings in time and money. Borehole-geophysical logging techniques permit the lateral extrapolation of data from a core hole. Log response is related to rock type, alteration, and the location and character of fractures. The geophysical logs that particularly are useful for these purposes are the acoustic televiewer and acoustic waveform, neutron and gamma, resistivity, temperature, and caliper. The acoustic-televiewer log of the borehole wall can provide high resolution data on the orientation and apparent width of fractures. In situ hydraulic tests of single fractures or fracture zones isolated by packers provide quantitative information on permeability, extent, and interconnection. The computer analysis of digitized acoustic waveforms has identified a part of the waveform that has amplitude variations related to permeabilities measured in the boreholes by packer tests. 38 refs., 37 figs., 4 tabs

  15. On Measurements of the Tide at Churchill, Hudson Bay

    Science.gov (United States)

    Ray, Richard D.

    2016-01-01

    Since the late 1990s the semi-diurnal tide at Churchill, on the western shore of Hudson Bay, has been decreasing in amplitude, with M(sub 2) amplitudes falling from approximately 154 cm in 1998 to 146 cm in 2012 and 142 cm in 2014. There has been a corresponding small increase in phase lag. Mean low water, decreasing throughout most of the twentieth century, has levelled off. Although the tidal changes could reflect merely a malfunctioning tide gauge, the fact that there are no other measurements in the region and the possibility that the tide is revealing important environmental changes calls for serious investigation. Satellite altimeter measurements of the tide in Hudson Bay are complicated by the seasonal ice cover; at most locations less than 40% of satellite passes return valid ocean heights and even those can be impacted by errors from sea ice. Because the combined TOPEX/Poseidon, Jason-1, and Jason-2 time series is more than 23 years long, it is now possible to obtain sufficient data at crossover locations near Churchill to search for tidal changes. The satellites sense no changes in M(sub 2) that are comparable to the changes seen at the Churchill gauge. The changes appear to be localized to the harbour, or to the Churchill River, or to the gauge itself.

  16. Validation of the Kidney Failure Risk Equation in Manitoba

    2017-04-01

    Full Text Available Background: Patients with chronic kidney disease (CKD are at risk to progress to kidney failure. We previously developed the Kidney Failure Risk Equation (KFRE to predict progression to kidney failure in patients referred to nephrologists. Objective: The objective of this study was to determine the ability of the KFRE to discriminate which patients will progress to kidney failure in an unreferred population. Design: A retrospective cohort study was conducted using administrative databases. Setting: This study took place in Manitoba, Canada. Measurements: Age, sex, estimated glomerular filtration rate (eGFR, and urine albumin-to-creatinine ratio (ACR were measured. Methods: We included patients from the Diagnostic Services of Manitoba database with an eGFR <60 mL/min/1.73 m 2 and ACR measured between October 2006 and March 2007. Five-year kidney failure risk was predicted using the 4-variable KFRE and compared with treated kidney failure events from the Manitoba Renal Program database. Sensitivity and specificity for KFRE risk thresholds (3% and 10% over 5 years were compared with eGFR thresholds (30 and 45 mL/min/1.73 m 2 . Results: Of 1512 included patients, 151 developed kidney failure over the 5-year follow-up period. The 4-variable KFRE showed a superior prognostic discrimination compared with eGFR alone (area under the receiver operating characteristic curve [AUROC] values, 0.90 [95% confidence interval {CI}: 0.88-0.92] for KFRE vs 0.78 [95% CI: 0.74-0.83] for eGFR. At a 3% threshold over 5 years, the KFRE had a sensitivity of 97% and a specificity of 62%. At 10% risk, sensitivity was 86%, and specificity was 80%. Limitations: Only 11.7% of stage 3-5 CKD patients had simultaneous ACR measurement. The KFRE does not account for other indications for referral such as suspected glomerulonephritis, polycystic kidney disease, and recurrent stone disease. Conclusions: The KFRE has been validated in a population with a demographic and referral

    2015-08-01

    Full Text Available Background: Diabetes and diabetes complications are substantially higher among Canadian First Nations populations compared with the general Canadian population. However, incidence data using detailed individual assessments from a population-based cohort have not been undertaken. Objective: We sought to describe incident diabetes, hypertension and dyslipidemia in a population-based cohort from a Manitoba Ojibway First Nation community. Design: Study data were from 2 diabetes screening studies in Sandy Bay First Nation in Manitoba, Canada, collected in 2002/2003 and 2011/2012. The cohort comprised of respondents to both screening studies (n=171. Health and demographic data were collected using a questionnaire. Fasting blood samples, blood pressure and anthropometric data were also collected objectively. Incident diabetes, hypertension and dyslipidemia were determined. Generalized linear models with Poisson distribution were used to estimate risk of incident diabetes and cardiometabolic conditions according to age and sex. Results: There were 35 (95% CI: 26, 45 new cases of diabetes among 128 participants without diabetes at baseline (27 or 3.3% per year. While participants who were 50 years and older at baseline had a significantly higher risk of incident diabetes at follow-up compared with participants aged 18–29 at baseline (p=0.012, more than half of the incident cases of diabetes occurred among participants aged less than 40 at baseline. There were 28 (95% CI: 20, 37 new cases of dyslipidemia at follow-up among 112 without dyslipidemia at baseline (25%. There were 36 (95% CI: 31, 42 new cases of hypertension among 104 participants without hypertension at baseline (34.6%. Women had half the risk of developing hypertension compared with men (p=0.039. Conclusions: Diabetes incidence is very high, and the number of new cases among those younger than 40 is a concern. Additional public health and primary care efforts are needed to address the

  18. The impact of the Commonwealth on Churchill's Europe

    Directory of Open Access Journals (Sweden)

    Cat Wilson

    2016-12-01

    Full Text Available Focusing from the time of his electoral defeat in July 1945 until the end of his second term as Prime Minister (October 1951-April 1955, this article examines the impact the Commonwealth had on Churchill’s Europe. Following the end of the Second World War Churchill’s Europe was fragile, yet not broken beyond all repair. Rather than weaken world organisations, such as the United Nations or a united post-war Europe, Churchill argued that the British Commonwealth would strengthen such liaisons. Analysing Churchill’s key relationships with the heads of the Commonwealth, reveal him to have been a true European – where security and democracy took precedence. His realism and pragmatism in the face of ever-changing, everevolving world-wide post-war alliances, where the Commonwealth arguably played a significant role, offers a stark contrast to the more common image of Churchill the “die-hard” imperialist.

  19. The strokes that killed Churchill, Roosevelt, and Stalin.

    From February 4 to 11, 1945, President Franklin D. Roosevelt of the United States, Soviet Union Premier Joseph Stalin, and British Prime Minister Winston Churchill met near Yalta in Crimea to discuss how post-World War II (WWII) Europe should be organized. Within 2 decades of this conference, all 3 men had died. President Roosevelt died 2 months after the Yalta Conference due to a hemorrhagic stroke. Premier Stalin died 8 years later, also due to a hemorrhagic stroke. Finally, Prime Minister Churchill died 20 years after the conference because of complications due to stroke. At the time of Yalta, these 3 men were the leaders of the most powerful countries in the world. The subsequent deterioration of their health and eventual death had varying degrees of historical significance. Churchill's illness forced him to resign as British prime minister, and the events that unfolded immediately after his resignation included Britain's mismanagement of the Egyptian Suez Crisis and also a period of mistrust with the United States. Furthermore, Roosevelt was still president and Stalin was still premier at their times of passing, so their deaths carried huge political ramifications not only for their respective countries but also for international relations. The early death of Roosevelt, in particular, may have exacerbated post-WWII miscommunication between America and the Soviet Union-miscommunication that may have helped precipitate the Cold War.

  20. Manitoba: path to a hydrogen future

    International Nuclear Information System (INIS)

    Parsons, R.V.; Crone, J.

    2003-01-01

    A hydrogen economy is not just about future clean energy but is also about future economic development. It is about new products, new services, new knowledge, and renewable energy sources that will be ultimately used by consumers in the future, and thus represent potential new economic opportunities. The concept of achieving important environmental and health goals through a cleaner energy economy, based on hydrogen, is not new. Similarly, the desire of individual jurisdictions to seek out and develop economic development opportunities is not new. The key question today becomes one of how to plot directions on hydrogen that will yield appropriate economic development gains in the future. While hydrogen offers significant promise, the prospect benefits are recognized to be still largely long-term in nature. In addition, the ability to identify appropriate future directions is clouded by a degree of 'hydrogen hype' and by a variety of major technical and market uncertainties. During 2002, a unique process was initiated within Manitoba combining these elements to work toward a Hydrogen Economic Development Strategy, a strategy that is ultimately intended to lead the province as a whole to determining our future economic niches for hydrogen. This paper describes the nature of the assessment process undertaken within Manitoba, the outcomes achieved and general insights of relevance to a broader audience. (author)

    While staying in the White House over Christmas 1941, Churchill developed chest pain on trying to open a window in his bedroom. Sir Charles Wilson, his personal physician, diagnosed a 'heart attack' (myocardial infarction). Wilson, for political and personal reasons, decided not to inform his patient of the diagnosis or obtain assistance from US medical colleagues. On Churchill's return to London, Wilson sought a second opinion from Dr John Parkinson who did not support the diagnosis of coronary thrombosis (myocardial infarction) and reassured Churchill accordingly.

    Willden, Ronald; Speed, Robert C.

    1974-01-01

    Churchill County, in west-central Nevada, is an area of varied topography and geology that has had a rather small total mineral production. The western part of the county is dominated by the broad low valley of the Carson Sink, which is underlain by deposits of Lake Lahontan. The bordering mountain ranges to the west and south are of low relief and underlain largely by Tertiary volcanic and sedimentary units. Pre-Tertiary rocks are extensively exposed east of the Carson Sink in the Stillwater Range, Clan Alpine Mountains, Augusta Mountains, and New Pass Mountains. The eastern valleys are underlain by Quaternary alluvial and lacustrine deposits contemporaneous with the western deposits of Lake Lahontan. The eastern mountain ranges are more rugged than the western ranges and have higher relief; the eastern valleys are generally narrower.

    Directory of Open Access Journals (Sweden)

    Allen Packwood

    2016-12-01

    Full Text Available The call for a “United States of Europe” is a recurring theme in the writings and speeches of Sir Winston Churchill from at least 1930, and reaches its culmination in his opening address to the Congress of Europe held at The Hague in May 1948. This article analyses Churchill’s own writings and oratory to trace the origins of his support for closer European union. Initially he envisaged Britain as a guarantor and facilitator of European unity, but by 1948 he had become an advocate of a role for Britain within Europe. This shift in thinking is followed through analysis of his language and explained in terms of the historical context.

    Newfoundland and Labrador Hydro has proposed to develop the hydroelectric potential of the lower Churchill River by constructing generating facilities at Gull Island and Muskrat Falls. This paper presented the results of a study that was conducted to collect baseline data on greenhouse gas (GHG) fluxes/emissions of carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) from the lower Churchill River, Smallwood reservoir, and natural lakes in the upper and lower Churchill regions. The purpose of the study was to compare GHG fluxes between the lower Churchill River, Smallwood reservoir and those of the nearby natural lakes and to compare GHG fluxes between the Smallwood reservoir and those of boreal reservoirs in northern Quebec. The paper provided a description of the site and the methodology for GHG flux measurement. The results and discussion focused on physical-chemical variables and GHG fluxes. The study results were to be used in the environmental assessment of the project. It was concluded that the lower Churchill River has higher CO 2 fluxes and lower CH 4 fluxes than the Smallwood reservoir and higher CO 2 fluxes than natural lakes in the region. There was no significant difference in N 2 O fluxes between the sampled waterbodies. Both CO 2 and CH 4 fluxes from the lower Churchill River were comparable to other Canadian reservoirs. 12 refs., 2 tabs., 6 figs

    Full Text Available The research is aimed at analyzing the ICSID (International Centre Settlement Investment Dispute decision in solving a dispute between Churchill Mining PLC and the Government of the Republic of Indonesia. The case brought to the public attention, because mining license owned by PT. Ridlatama which acquired from Churchill Mining PLC had been revocated. Churchill Mining PLC holds 75% share of PT. Ridlatama and it suffered losses caused by the revocation of its mining license. Churchill Mining PLC filed the case to the local court but it failed. Churchill Mining PLC then sought ruling from International arbitration or ICSID. On December 6, 2016, ICSID issued a decision that clearly threw out Churchill Mining PLC claim. ICSID, the World Bank court, ordered the firm to pay a total of US$.9.446.528 in cost to the Government of the Republic of Indonesia. It is based on the evidences that the UK-Australia company did the fraud and had document forgery of coal mining permit in East Kutai, Indonesia. So the firm has violated the Bilateral Investment Treaties between Indonesia-UK and Indonesia-Australia.

    The objective of this study was to document the relationship between First Nation's community characteristics and the rates of hospitalization for Ambulatory Care Sensitive Conditions (ACSC) in the province of Manitoba, Canada. A population-based time trend analysis of selected ACSC was conducted using the de-identified administrative data housed at the Manitoba Centre for Health Policy, including vital statistics and health information. The study population included all Manitoba residents eligible under the universal Manitoba Health Services Insurance Plan and living on First Nation reserves between 1984/85 and 2004/05. Twenty-nine ACSC defined using 3, 4 and 5 digit ICD-9-CM and ICD-10-CM codes permitted cross-sectional and longitudinal comparison of hospitalization rates. The analysis used Generalized Estimated Equation (GEE) modeling. Two variables were significant in our model: level of access to primary health care on-reserve; and level of local autonomy. Communities with local access to a broader complement of primary health care services showed a lower rate of hospitalization for ACSC. We also examined whether there was a significant trend in the rates of hospitalization for ACSC over time following the signature of an agreement increasing local autonomy over resource allocation. We found the rates of hospitalization for ACSC decreased with each year following the signature of such an agreement. This article demonstrates that communities with better local access to primary health care consistently show lower rates of ACSC. Secondly, the longer community health services have been under community control, the lower its ACSC rate. (c) 2010 Elsevier Ltd. All rights reserved.

    1999-06-01

    In light of ongoing discussions about health care policy, this study offered a method of calculating costs at Manitoba hospitals that compared relative costliness of inpatient care provided in each hospital. This methodology also allowed comparisons across types of hospitals-teaching, community, major rural, intermediate and small rural, as well as northern isolated facilities. Data used in this project include basic hospital information, both financial and statistical, for each of the Manitoba hospitals, hospital charge information by case from the State of Maryland, and hospital discharge abstract information for Manitoba. The data from Maryland were used to create relative cost weights (RCWs) for refined diagnostic related groups (RDRGs) and were subsequently adjusted for Manitoba length of stay. These case weights were then applied to cases in Manitoba hospitals, and several other adjustments were made for nontypical cases. This case mix system allows cost comparisons across hospitals. In general, hospital case mix costing demonstrated variability in hospital costliness, not only across types of hospitals but also within hospitals of the same type and size. Costs at the teaching hospitals were found to be considerably higher than the average, even after accounting for acuity and case mix.

    1996-01-01

    Manitoba Hydro was the first Canadian utility to initiate a program to decontaminate insulating oil contaminated with polychlorinated biphenyls (PCBs). This paper describes Manitoba Hydro's recovery, reuse and recycling program, operated out of the utility's Waverley Service Centre (WSC). The WSC is a central facility serving to phase out and and destroy PCBs which remain in Manitoba Hydro's electrical system. Several hundred thousand litres of PCB-contaminated insulating oil are decontaminated annually at the WSC. The decontaminated oil is then reconditioned for reuse within the system operations. A PCBX unit was purchased from Sun Ohio for the decontamination of insulating oils containing PCBs. PCB decontamination is achieved through a chemical dechlorination treatment process. The PCBX treatment unit and the PCB storage building were described. 18 refs., 8 figs

    2006-01-01

    Manitoba currently generates 5500 MW of electricity, and has the potential to add another 5000 MW of clean energy. Nearly 2000 MW of Manitoba's electricity is currently being sold to the United States. New transmission sites will ensure both grid reliability and energy security for Ontario, and power exchanges are expected to reduce costs. This presentation provided details of a memorandum of understanding (MOU) between Ontario and Manitoba concerning energy sales across existing and future transmission infrastructure. Peak energy sales were expected to reach 1000 MW in the near future. Options for the interconnection included direct high voltage direct current (HVDC) lines to Sudbury as well as lines through Thunder Bay and Winnipeg. Manitoba's existing hydro sites were outlined, and potential sites were reviewed. In addition to presenting new supply options, this presentation described generation and transmission approval processes, as well as construction schedules for new sites and interconnection points. It was concluded that while there is currently a provincial focus on electricity supply and demand, new generation technologies will make interprovincial electricity agreements economically viable. tabs., figs

    This annual report states the objectives and achievements of each of the Department of Energy and Mines branches in the same sequence as in the Dept.'s appropriation structure in the Main Estimates of the Expenditure for the Province. Details of the Dept.'s financial performance, together with a 5 year historical table of departmental spending and staffing levels, are provided in the Financial Information Section. Manitoba's oil and gas sector, though small by regional or international standards, is a significant part of the provincial economy. In 1998, Manitoba produced 634,071 cubic m of oil having a total value of about 27% of the province's refined petroleum products needs. In 1998, the petroleum industry spend more than $61 million in Manitoba to explore and develop new oil pools, and to operate the approximately 1,900 active wells in the province. The petroleum industry employs directly and indirectly over 600 people. In 1998/99, royalties, production taxes and revenue from the leasing of Crown owned oil and gas rights added $34 million to the Provincial treasury. The Petroleum and Energy Branch administers the Oil and Gas Act regulations governing the exploration, development, production, transportation and storage of crude oil and natural gas. The Dept. in conjunction with the Manitoba Oil Museum hosted the 1998 Manitoba Oil Show. Manitobans spend about $2.8 billion annually to heat and light their homes, power business, industry and agriculture and fuel their transportation needs. The installed provincial electrical generating capacity is 5,137 megawatts, and the Branch administers the Energy Act. refs

    This paper reviews Churchill's illness in Carthage in December 1943. It was characterised by fever that lasted 6 days, left lower lobe pneumonia and two episodes of atrial fibrillation. He was managed in a private villa by Lord Moran, his personal physician, with the assistance of two nurses and the expert advice of colleagues. Sulphadiazine and digitalis leaf were prescribed and Churchill recovered. It is remarkable that, despite the severity of his illness, he continued to direct the affairs of State from his bed.

  17. Pathologizing Indigenous Suicide: Examining the Inquest into the Deaths of C.J. and C.B. at the Manitoba Youth Centre

    Directory of Open Access Journals (Sweden)

    Mandi Gray

    2016-08-01

    Full Text Available This paper examines the inquest into the deaths by suicide of two Manitoba Indigenous female youth while imprisoned in the Manitoba Youth Centre in Winnipeg, Canada. The purpose of this paper is to analyze the inquest as a discursive space that relies primarily on expert knowledge from law and psychiatry. It studies the inquest’s recommendations for preventing future deaths under similar circumstances. Utilizing Heidi Rimke’s conceptualization of psychocentrism, this analysis examines how suicide discourse in this inquest reduces various manifestations of violence to racial defects and places responsibility on the deceased girls for their inability to have coped with the tortuous conditions of imprisonment.   I argue that contemporary understandings of Indigenous suicide in custody systematically erase histories of colonial violence and erroneously reduce suicide to an issue of individual pathology that can be identified and treated through medicalization, psychiatrization and criminalization.

    Full Text Available Introduction: Although indoor tanning causes cancer, it remains relatively common among adolescents. Little is known about indoor tanning prevalence and habits in Canada, and even less about associated behaviours. This study explores the prevalence of adolescent indoor tanning in Manitoba and its association with other demographic characteristics and health behaviours. Methods: We conducted secondary analyses of the 2012/13 Manitoba Youth Health Survey data collected from Grade 7 to 12 students (n = 64 174 and examined associations between indoor tanning (whether participants had ever used artificial tanning equipment and 25 variables. Variables with statistically significant associations to indoor tanning were tested for collinearity and grouped based on strong associations. For each group of highly associated variables, the variable with the greatest effect upon indoor tanning was placed into the final logistic regression model. Separate analyses were conducted for males and females to better understand sex-based differences, and analyses were adjusted for age. Results: Overall, 4% of male and 9% of female students reported indoor tanning, and prevalence increased with age. Relationships between indoor tanning and other variables were similar for male and female students. Binary logistic regression models indicated that several variables significantly predicted indoor tanning, including having part-time work, being physically active, engaging in various risk behaviours such as driving after drinking for males and unplanned sex after alcohol/drugs for females, experiencing someone say something bad about one's body shape/size/appearance, identifying as trans or with another gender, consuming creatine/other supplements and, for females only, never/rarely using sun protection. Conclusion: Indoor tanning among adolescents was associated with age, part-time work, physical activity and many consumption behaviours and lifestyle risk factors. Though

    The Manitoba Hazardous Waste Management Corporation is charged with the responsibility of implementing a hazardous waste management system in the province. A review was undertaken of the planning work performed to date and of the Corporation's development strategy. The evaluation was based on a review of the literature and on experience with hazardous waste planning, management, and engineering. To facilitate evaluation, the development strategies were visualized as made up of 3 logical components: the mechanisms or business vehicles used; the rates of development employed; and the geographical locations in which the activities take place. Based on ownership or funding source, 3 business development options were identified: public corporation, private enterprise, and joint venture. The only two options possible in terms of rate of development are incremental and immediate. Three general locations were considered; in Manitoba, outside Manitoba, or a combination of both. Results showed that a joint venture is a good option since it offers a good tradeoff to minimize expenditures between public and private financing, and it enables combining the flexibility and freedom of action of a private corporation with the responsibility of a public corporation. The incremental approach provides more flexibility than immediate development and is the most practical solution to the many uncertainties of the hazardous waste problem. This approach is nominally more costly because it takes longer and cannot capitalize on economies of scale, but it also minimizes the risk of making the wrong capital investment and is therefore a safer investment approach. 108 refs., 28 figs., 15 tabs.

    The quest for economic efficiency, or lowest cost, in the electricity supply industry is furthered by trading between high and low cost utilities, one aspect being transporting or wheeling power through the transmission system of a third party. Some of the pressures and constraints limiting wheeling are discussed. A simple formula is presented for determining whether trading and wheeling are worthwhile. It is demonstrated for assumed capital and operating cost levels, the viability of nine cases where bulk power or economy energy would need to be wheeled across provincial boundaries in order to reach potential buyers. Wheeling in Canada is different from the situation in the USA, due to large distances spanned by Canadian utilities and because most are provincial crown corporations, with different territorial interests and profit motivations than investor-owned utilities. Most trading in electricity has been between contiguous neighbours, for mutual advantage. New technology allows power transmission over distances of up to 1000 miles, and the economics of Canada's electrical supply could be improved, with means including access to low cost coal of Alberta, and remote hydro in British Columbia, Manitoba, Quebec and Labrador. Nuclear plants could be located anywhere but suffer from an unfriendly public attitude. A bridge across the Prairies appears uneconomic due to cost of transmission, and also due to low valuation given to Alberta coal. 7 refs., 2 figs., 3 tabs

    Decades of hospital restructuring in Canada resulted in significant reductions of nursing leadership positions and altered a nursing infrastructure important for guiding patient care. The importance of acquiring nursing leadership skills to address the negative effects of restructuring is advocated by Canadian nursing bodies. To describe a service innovation for a nursing community. The librarians of the University of Manitoba Health Sciences Libraries (UMHSL) created an online nursing leadership literature centre to support a leadership programme launched by the Nursing Leadership Council (NLC) of the Winnipeg Regional Health Authority. The article will contribute to the body of literature about health library services for nurses. The creation of the service is described. A literature search was undertaken to determine what services have been implemented by librarians for nursing leadership programmes, as well as to review the literature with regard to contributions made by librarians for nursing communities. The literature service, comprised of 19 webliographies based on the NLC's leadership topics, is available on the UMHSL website. A webliography, by definition, is a list of electronic works relating to a particular topic. The NLC created its own website that provides nurses with a means to identify, enhance and evaluate leadership competencies, and which is linked to the UMHSL website. The contributions of the UMHSL librarians to this project support the goals of instilling leadership skills in nurses, encouraging evidence-based nursing practice, and transforming a practice environment to meet the ultimate goal of effective patient care.

    Manitoba has low electricity rates, the highest proportion of renewables, and a legislated commitment to reduce greenhouse gases. However, the province still relies heavily on oil as everyone else. The mix of energy opportunities in Manitoba were highlighted in this presentation, with particular reference to the commercialization of electric vehicles. Several photographs were presented of the Toyota plug-in hybrid vehicle and a plug-in hybrid electric demonstration vehicle. A demonstration project overview was offered that used technology from A123 Systems Inc. The conversion module and vehicle users were profiled. Topics that were presented related to the demonstration project included monitoring; gasoline fuel economy results; fuel economy variability; cold weather operation; cold weather issues; battery upgrade solutions; and highly qualified personnel. It was concluded that in terms of follow-up, there is a need to combine findings of current plug-in hybrid electric vehicle demonstration with those for the new Toyota production plug-in hybrid vehicles. Key next steps for the demonstration are to address cabin heating requirements; better characterizing winter performance; and implementation of IPLC units on all plug-in hybrid electric vehicles for electricity consumption. figs.

To highlight aspects of the situational analysis of the Manitoba Health, Healthy Living and Seniors (MHHLS's) AEFI surveillance system and to demonstrate how common business techniques could be usefully applied to a provincial vaccine safety monitoring program. Situational analysis of the AEFI surveillance system in Manitoba was developed through a strengths-weaknesses-opportunities-threats (SWOT) analysis and informed by the National Immunization Strategy vaccine safety priorities. Strategy formulation was developed by applying the threats-opportunities-weaknesses-strengths (TOWS) matrix. Thirteen strategies were formulated that use strengths to either take advantage of opportunities or avoid threats, that exploit opportunities to overcome weaknesses, or that rectify weaknesses to circumvent threats. These strategies entailed the development of various tools and resources, most of which are either actively underway or completed. The SWOT analysis and the TOWS matrix enabled MHHLS to enhance the capacity of its vaccine safety program.

    A provincial Crown corporation, Manitoba Hydro serves approximately 502,000 customers throughout Manitoba with electric energy, and provides natural gas service to 251,000 customers in several communities in southern Manitoba. In addition, Manitoba Hydro exports electricity to electric utilities and marketers in the mid-western United States, Ontario, and Saskatchewan. In 2002, Winnipeg Hydro was purchased from the City of Winnipeg. Records were broken for historical peak demand for electricity (24 February 2003) and natural gas (22 January 2003). A study of wind power generation was launched, with seven sites being monitored. A Power Smart program focusing on geothermal heat pump systems also offered assistance to Manitoba homeowners. Successful conversion of the Selkirk Generating Station from coal to natural gas was achieved. In Brandon, a 260 mega watt (MW) natural gas combustion turbine plant was opened. Over $29 million in loans were issued to customers under the Home Comfort and Energy Savings Program. Electricity rates for residential customers remained unchanged, as did those for large industrial customers. Approval was received by the National Energy Board to export 500 MW of electricity to Northern States Power. A new international interconnection was brought into service in November 2002 between Glenboro, Manitoba and Harvey, North Dakota. The ISO 14001 international certification for environmental management systems was awarded to Manitoba Hydro. tabs., figs

    Fourteen female patients with primary urethral carcinoma were treated at the Manitoba Cancer Foundation in the last twenty-nine years. The relationship of natural history to the stage, location, and therapeutic modality has been reviewed. A higher stage and length of urethral involvement affected prognosis negatively, whereas lower stage had a positive prognostic effect and location of tumor had no prognostic influence. Two patients with Stage C, who failed to received inguinal node radiotherapy, died of disease recurring in the inguinal area. Patients who received inguinal radiation (3 patients Stages B, C, and D1) had no regional recurrence. It is suggested that, for all female urethral carcinoma, bilateral ilioinguinal nodes be included in the radiation field. For radical treatment, iridium 192 insertion in combination with external beam treatment is recommended

  17. FEMINIST PERSPECTIVE OF CROSS-GENDER POWER RELATION IN CARYL CHURCHILL'S TOP GIRLS

    Directory of Open Access Journals (Sweden)

    2002-01-01

    Full Text Available Top Girls, one of Caryl Churchill's most popular plays, describes the lives of six female characters coming from different centuries. Each of them has their own story to tell, as they have all been victimized by the patriarchal system in the century when they live and have resisted the system with different strategies. They either employ roles that are traditionally reserved for men or they adopt the archetypically feminine qualities. Despite their resistance and success, they find themselves unhappy and unsatisfied over their achievements. Thus this raises the question of the effectiveness of the feminist movement.

    More than half of the world`s peatlands occur in the boreal zone (45 - 60 deg C N. lat), a region which global climate models predict will experience large changes in temperature and precipitation with increasing atmospheric CO{sub 2} concentrations. The northern part of the boreal zone is characterised by discontinuous permafrost, an area that is particularly sensitive to climate change with the possible degradation and thawing of frozen peat. Peatlands are large sources of atmospheric methane (CH{sub 4}), an important greenhouse gas. Yet few measurements of methane have been conducted in discontinuous permafrost environments. As part of the Boreal Ecosystem-Atmosphere Study (BOREAS), CH{sub 4} flux was measured in a diverse peatland complex (bogs, fens, peat plateaus, and collapse scars), representing the complete range of temperature, moisture, and plant community gradients found in northern peatlands. The measurement period May to September 1994 was one of the warmest and driest seasons on record, which provided an opportunity to observe the short-term responses of different parts of the peatland ecosystem to a warmer and drier climate as an analog to predicted climate change in the region.

    A revised conceptual hydrogeologic model of regional groundwater flow in the crystalline rocks of the Whiteshell Research Area (WRA) has been developed by a team of AECL geoscientists. The revised model updates an earlier model developed in 1985, and has a much broader database. This database was compiled from Landsat and airborne radar images, geophysical surveys and surface mapping, and from analyses of fracture logs, hydraulic tests and water samples collected from a network of deep boreholes drilled across the WRA. The boundaries of the revised conceptual model were selected to coincide with the natural hydraulic boundaries assumed for the regional groundwater flow systems in the WRA. The upper and lower boundaries are the water table and a horizontal plane 4 km below ground surface. For modelling purposes the rocks below 4 km are considered to be impermeable. The rocks of the modelled region were divided on the basis of fracture characteristics into three categories: fractured zones (FZs); moderately fractured rock (MFR); and sparsely fractured rock (SFR). The FZs are regions of intensely fractured rock. Seventy-six FZs were selected to form the fault framework within the revised conceptual model. The physical rock/water properties of the FZs, MFR and SFR were selected by analysis of field data from hydraulic and tracer tests, laboratory test data and water quality data. These properties were used to define a mathematical groundwater flow model of the WRA using AECL's MOTIF finite element code (Ophori et al. 1995, 1996). (author). 29 refs., 4 tabs., 12 figs

    Aboriginal peoples in Canada are comprised of First Nations, Métis, and Inuit. Health care services for First Nations who live on rural and remote reserves are mostly provided by the Government of Canada through the federal department, Health Canada. One Health Canada policy, the evacuation policy, requires all First Nations women living on rural and remote reserves to leave their communities between 36 and 38 weeks gestational age and travel to urban centres to await labour and birth. Although there are a few First Nations communities in Canada that have re-established community birthing and Aboriginal midwifery is growing, most First Nations communities are still reliant on the evacuation policy for labour and birthing services. In one Canadian province, Manitoba, First Nations women are evacuated to The Pas, Thompson, or Winnipeg but most - including all women with high-risk pregnancies - go to Winnipeg. To contribute scholarship that describes First Nations women's and community members' experiences and perspectives of Health Canada's evacuation policy in Manitoba. Applying intersectional theory to data collected through 12 semi-structured interviews with seven women and five community members (four females, one male) in Manitoba who had experienced the evacuation policy. The data were analyzed thematically, which revealed three themes: resignation, resilience, and resistance. The theme of resignation was epitomized by the quote, "Nobody has a choice." The ability to withstand and endure the evacuation policy despite poor or absent communication and loneliness informed of resilience. Resistance was demonstrated by women who questioned the necessity and requirement of evacuation for labour and birth. In one instance, resistance took the form of a planned homebirth with Aboriginal registered midwives. There is a pressing need to improve the maternity care services that First Nations women receive when they are evacuated out of their communities, particularly

    This study sought to evaluate the rate of appendiceal involvement in non-serous mucinous and endometrioid-associated epithelial ovarian cancers. The Manitoba Cancer Registry and CancerCare database were used to find all women with non-serous epithelial ovarian, fallopian tube, or primary peritoneal cancer between 1995 and 2011. All patients with an appendectomy were then identified, and their final pathology findings were reviewed. Women who did not receive treatment or lacked follow-up were excluded. We identified 338 patients from 1995-2011 with no prior appendectomy. Of these, 16.6% received an appendectomy, and 22.8% were clinically evaluated. Most cases within this cohort were mucinous (62%) and stage 1 (63%). Four appendiceal metastases were identified (7.2%), and one half appeared clinically normal at the time of surgery (3.6%). Within the mucinous histologic type, 32.7% of patients received an appendectomy, with a metastatic rate of 5.7%. Of the 127 endometrioid cases, only 10 patients received an appendectomy, and 2 were found to have metastases. No metastases were found in the 85 patients in the clear cell cohort, only 5 of whom received an appendectomy. Routine appendectomy or clinical assessment of the appendix is valuable for all non-serous ovarian cancers. The rate of involvement for endometriosis-associated ovarian cancers may be significantly higher than expected, and further studies need to be conducted.

    Dick, C.J.

    1992-04-01

    The potential effect of the 'no net loss' principle on Manitoba Hydro's Conawapa hydroelectric project is assessed, including an examination of the process by which the no net loss principle will likely be implemented at the site, based on a review of past applications of the policy. The no net loss principle was developed by the federal Department of Fisheries of Oceans (DFO) as part of their 1986 Policy for the Management of Fish Habitats. The overall objective of the policy is to achieve a net gain of the productive capacity of fish habitats in Canada. Application of the policy to specific developments is based upon maintaining the productive capacity of fish habitats as well as the needs of users groups. The policy has not yet been applied to an inland hydroelectric project. Achieving no net losses may be difficult in regard to large projects such as a hydro dam, however a review of past applications of the policy reveal a number of concepts that have been employed by the DFO when applying the no net loss principle. These concepts were applied to the Conawapa project to make recommendations to achieve no net loss if the project is developed. Mitigation and compensation measures must be developed for both brook trout and lake sturgeon habitat, and should include a combination of habitat enhancement and increased protection and compliance. Measures should also be developed for other species such as lake cisco and lake whitefish, both of which may be a food source for beluga whales. The Conawapa forebay may be given consideration as compensation for lost habitat. 81 refs., 11 figs., 2 tabs

    Full Text Available To examine the association between maternal depression and anxiety disorders (MDAD and child development assessed during the kindergarten year.Administrative data from several health and social databases in Manitoba, Canada, were used to study 18,331 mother-child pairs. MDAD over the period from one year prior to the child's birth to the kindergarten year was defined using physician diagnoses and filled prescriptions. Child development was assessed during the kindergarten year using the Early Development Instrument (EDI which measures vulnerability across five domains of development. Structural equation modeling was used to examine associations between timing, recurrence and severity of MDAD and child outcomes. Health at Birth (preterm, low birth weight, neonatal intensive care stay and long birth hospitalization, Family Context (teen mother, lone parent, socio-economic status (SES, child age and child sex were covariates.MDAD had a modest negative association with child EDI scores across all models tested, particularly for social, emotional and physical development. Prenatal MDAD had a stronger negative association with outcomes than other time periods; however, recurrent MDAD had a stronger negative association with outcomes than any specific time period or MDAD severity. The influence of MDAD was mediated by Family Context, which had a strong, negative association with outcomes, particularly language and cognitive development.The number of time periods a child was exposed to MDAD in early childhood was more negatively associated with five areas of child development than timing or severity. Prenatal exposure may be more sensitive to MDAD than other time periods. The familial context (teen mother, lone parenthood and low SES had a stronger influence on child outcomes than MDAD. Findings can be used to inform interventions which address maternal mental health from the prenatal period onward, and to support disadvantaged families to encourage

    Fox, J.N.; Martinuk, C.D.

    1994-01-01

    The geology and reservoir characteristics of Manitoba's oil producing horizons are described, and exploration and development prospects are reviewed. Southwestern Manitoba occupies part of the northeastern flank of the Williston Basin. Paleozoic, Mesozoic, and Cenozoic rocks form a basinward thickening wedge of sedimentary strata that reach a total thickness of 2,300 m in the southwest corner of the province. To date, oil production in Manitoba is restricted to the sandstones of the Middle Jurassic, the Jurassic Amaranth Formation, the Mississippian Bakken Formation, and the carbonates of the Mississippian Lodgepole and Mission Canyon Formations. The deeper Ordovician, Silurian, and Devonian formations offer oil and gas potential but remain largely undrilled. Total recoverable reserves are ca 36 million m 3 and remaining proved reserves are ca 6 million m 3 . Manitoba had a resurgence in petroleum activity in 1993; 102 wells were licensed, compared to an annual average of 61 over the past five years. More Crown land was disposed at the two lease sales in 1993 than had been leased in the previous five years. Low Crown land price is one competitive advantage available to Manitoba oil producers. Other advantages include low drilling and completion costs, low drilling density, a competitive and stable fiscal regime, drilling and exploration incentives, and unrestricted access to markets. Sample economics are included to illustrate the attractiveness of vertical and horizontal drilling opportunities in Manitoba. 8 refs., 6 figs., 7 tabs

    Geology and reservoir characteristics of Manitoba's producing horizons were described, and recent activity in exploration and development prospects for the immediate future were reviewed. These prospects have improved considerably, thanks to recent efforts of the Manitoba Department of Energy and Mines to ensure that barriers to petroleum investment are eliminated. As a result of these and related efforts by the Manitoba government the investment climate is stable and competitive. Advantages in Manitoba include availability of Crown land at comparatively low prices, drilling and exploration incentives, low drilling and completion costs, and easy access to markets. Development drilling opportunities exist for each of Manitoba's five producing formations (the sandstones of the Jurassic Melita and Amaranth formations, and the Mississippian Bakken Formation, and the carbonates of the Mississipian Lodgepole and Mission Canyon formations). Sample economic scenarios run on three development scenarios and modelled after typical Manitoba oil play were very favorable, indicating a potential rate of return on investments of 25 to 37 per cent and pay-out in 2.6 to 3.2 years. 10 refs., 7 tabs., 5 figs

  7. In the Loop : A look at Manitoba's geothermal heat pump industry

    International Nuclear Information System (INIS)

    2002-03-01

    This booklet outlines the position of Manitoba's heat pump market with the objective of promoting the widespread use of geothermal heat pumps in the province. It makes reference to the size of the market, customer satisfaction with heat pumps, and opinion of key players in the industry regarding the heat pump market. The information in this booklet is drawn on market research and lessons learned in Europe and the United States. In October 2001, a group of key stakeholders in Manitoba's heat pump market attended an industry working meeting to address the issues of market barriers, market enablers and market hot buttons. Market barriers include the high cost of geothermal heat pumps, lack of consumer awareness, lack of consistent standards, and public perception that heat pumps are not reliable. Market enablers include the low and stable operating costs of geothermal heat pumps, high level of comfort, high quality and reliability of geothermal heat pumps, and financial incentives under Manitoba Hydro's Power Smart Commercial Construction Program. Market hot buttons include lowering the cost of geothermal heat pumps, improving industry performance, increasing consumer awareness, and forming a Manitoba Geothermal Trade Association. Approximately 2,500 heat pump systems have been installed in Manitoba. In 2001, heat pump sales in Manitoba grew 40 per cent. 1 tab., 6 figs

Roosevelt (1 882-1945 were masters of the English language and effective orators, rallying their people through word and deed to fight as allies against the dictatorial powers during the Second World War. Their public speeches and interviews are replete with proverbs, proverbial expressions, and other phraseologisms. This is also true for their private and secretive letters, messages, memoranda, and telegrams, as can be seen from the materials that Warren F. Kimball edited in the three volumes of Churchill & Roosevelt: The Complete Correspondence (Princeton, NJ: Princeton University Press, 1984. The proverbial language, especially metaphorical texts referring to the body, animals, and the military, gives their important communications a lively and humane flavor that illustrates their deep friendship, trust, and support of each other. Frequently used as metaphorical arguments, these proverbial interjections into an otherwise factual epistolary exchange from 1933 to 1945 bear witness to the determination of these two world leaders to win the struggle for a free world.

    Sampling expeditions to Churchill in the Canadian subarctic were completed with the aim of compiling a molecular-assisted survey of the macroalgal flora (seaweeds) for comparison to published accounts for this area, which are based on morphological identifications. Further, because the Churchill region was covered by ice until recently (~10,000 before present), the current algal flora has had to migrate from adjacent waters into that region. We used our DNA barcode data to predict the relative contribution of the North Atlantic and North Pacific floras (Likely Source Region) in repopulating the Churchill region following the most recent glacial retreat. We processed 422 collections representing ~50 morpho-species, which is the approximate number reported for this region, and generated DNA barcode data for 346 of these. In contrast to the morpho-species count, we recovered 57 genetic groups indicating overlooked species (this despite failing to generate barcode data for six of the ~50 morpho-species). However, we additionally uncovered numerous inconsistencies between the species that are currently listed in the Churchill flora (again as a result of overlooked species diversity, but combined with taxonomic confusion) and those identified following our molecular analyses including eight new records and another 17 genetic complexes in need of further study. Based on a comparison of DNA barcode data from the Churchill flora to collections from the contiguous Atlantic and Pacific floras we estimate that minimally 21% (possibly as much as 44%) of the Churchill flora was established by migration from the Pacific region with the balance of species arriving from the Atlantic (predominantly North American populations) following the last glacial retreat. Owing to difficulties associated with the morphological identification of macroalgae, our results indicate that current comprehension of the Canadian Arctic flora is weak. We consider that morphology-based field

    While advances in genome sequencing technology make population-scale genomics a possibility, current approaches for analysis of these data rely upon parallelization strategies that have limited scalability, complex implementation and lack reproducibility. Churchill, a balanced regional parallelization strategy, overcomes these challenges, fully automating the multiple steps required to go from raw sequencing reads to variant discovery. Through implementation of novel deterministic parallelization techniques, Churchill allows computationally efficient analysis of a high-depth whole genome sample in less than two hours. The method is highly scalable, enabling full analysis of the 1000 Genomes raw sequence dataset in a week using cloud resources. http://churchill.nchri.org/.

  14. Participant outcomes, perceptions, and experiences in the Internationally Educated Engineers Qualification Program, University of Manitoba: An exploratory study

    Science.gov (United States)

    Friesen, Marcia R.

    Immigration, economic, and regulatory trends in Canada have challenged all professions to examine the processes by which immigrant professionals (international graduates) achieve professional licensure and meaningful employment in Canada. The Internationally Educated Engineers Qualification Program (IEEQ) at the University of Manitoba was developed as an alternate pathway to integrate international engineering graduates into the engineering profession in Manitoba. However, universities have the neither mandate nor the historical practice to facilitate licensure for immigrant professionals and, thus, the knowledge base for program development and delivery is predominantly experiential. This study was developed to address the void in the knowledge base and support the program's ongoing development by conducting a critical, exploratory, participant-oriented evaluation of the IEEQ Program for both formative and summative purposes. The research questions focussed on how the IEEQ participants perceived and described their experiences in the IEEQ Program, and how the participants' outcomes in the IEEQ Program compared to international engineering graduates pursuing other licensing pathways. The study was built on an interpretivist theoretical approach that supported a primarily qualitative methodology with selected quantitative elements. Data collection was grounded in focus group interviews, written questionnaires, student reports, and program records for data collection, with inductive data analysis for qualitative data and descriptive statistics for quantitative data. The findings yielded rich understandings of participants' experiences in the IEEQ Program, their outcomes relative to international engineering graduates (IEGs) pursuing other licensing pathways, and their perceptions of their own adaptation to the Canadian engineering profession. Specifically, the study suggests that foreign credentials recognition processes have tended to focus on the recognition and

    The Manitoba Perinatal Screening Program is guided by a committee of medical specialists with skills in the diagnosis and management of disorders of metabolism in the newborn. The program is voluntary and is centralized at Cadham Provincial Laboratory, in Winnipeg. A filter card blood specimen is collected from newborns on discharge from hospital, and a filter card urine sample is collected and mailed to the laboratory by the mother when the infant is about 2 weeks of age. The overall compliance rates for the blood and urine specimens are approximately 100% and 84% respectively. The blood specimen is screened for phenylalanine and other amino acids, thyroxine, galactose, galactose-1-phosphate and biotinidase. The urine specimen is screened for amino acids, including cystine, as well as methylmalonic acid and homocystine. Between 1965 and 1985, 83 cases of metabolic disorders were detected, including 23 cases of primary hypothyroidism, 14 of classic phenylketonuria, 5 of galactosemia variants, 3 of galactosemia, 2 of maple syrup urine disease and 1 of hereditary tyrosinemia. The direct cost per infant screened is $5.50, and the cost:benefit ratio is approximately 7.5:1. Maternal serum alpha-fetoprotein screening is being made available as the necessary supporting clinical facilities become available. On the basis of this experience, the author outlines the components that are important for an effective screening program. PMID:3676929

    2005-01-01

    The renewal clause of the 1969 power contract between Hydro-Quebec and the Churchill Falls (Labrador) Corporation (CFLCo) takes effect in 2016. The contract concerns the development and sale of electricity from the Churchill Falls hydro site and has been a matter of discontent in Newfoundland and Labrador because it stipulates that almost all of the power be sold to Hydro-Quebec on a very long-term basis at very low and declining prices. The government of Newfoundland and Labrador has challenged the contract in several ways since the 1970s, all unsuccessfully. During the renewal period, the price is preset at 2 mills (0.2 cents) per kilowatt hour. Even in the late 1960s, this price was extraordinarily low and not achievable from any new energy source. The average wholesale price of electricity in Ontario in 2004 was 52.2 mills per kilowatt hour. With 30 million megawatt hours of electricity involved in this renewal, the potential gap between the value of the power and the amount paid to CFLCo was about $1 billion a year by 2004 and rising. This paper presents the results of the first systematic investigation into how such an extraordinary onerous condition got into the contract. It considers the process that led to the contract and related arrangements. It also presents uncited archival documentation that gives new and revealing facts about the origins of the renewal clause. The findings give rise to questions of business ethics and law. This paper also reviews the early discussions and the interrelated commercial and political challenges that had to be overcome for the two provinces to come to an agreement on a comprehensive Letter of Intent. The contract negotiations and events that led to the renewal clause were outlined along with the implications for Hydro-Quebec, CFLCo and the government of Newfoundland. 13 refs., 2 appendices

    Full Text Available The aim of the present study was to determine whether Clostridium difficile was present in uncooked retail ground beef and ground pork products sold in Winnipeg, Manitoba. Using an alcohol treatment protocol and inoculation of cultures on C difficile Moxalactam Norfloxacin (CDMN, toxigenic C difficile was found in 6.3% of 48 meat samples. The C difficile isolates belonged to different pulsotypes, all of which had been previously isolated from the stool of Manitoba patients with C difficile disease. Because cooking of meat will not eradicate C difficile spores, this raises a concern regarding potential foodborne transmissibility of this organism.

  1. On elevated fluoride and boron concentrations in groundwaters associated with the Lake Saint-Martin impact structure, Manitoba

    International Nuclear Information System (INIS)

    Desbarats, Alexandre J.

    2009-01-01

    Hydrogeological investigations conducted by the Geological Survey of Canada in the Lake Saint-Martin region of Manitoba have confirmed earlier reports of naturally elevated F - and B concentrations in local groundwaters. Fluoride and B concentrations are highly correlated (r 2 = 0.905) and reach 15.1 mg/L and 8.5 mg/L, respectively. Virtually all groundwaters with F - concentrations greater than the drinking water limit of 1.5 mg/L are from wells within the Lake Saint-Martin impact structure, a 208 Ma complex crater 23 km in diameter underlying a large part of the study area. The high-F - groundwaters can be classified into two groups according to their anionic and isotopic compositions. Group I samples consist of Na-mixed anion groundwaters, with Cl greater than 100 mg/L and highly depleted 18 O compositions indicative of recharge under much cooler climatic conditions than at present. Samples belonging to this group exhibit a striking relationship to crater morphology, and are found in an arcuate belt within the southern rim of the impact structure. Group II high-F - samples consist of Na-HCO 3 -SO 4 groundwaters, with little Cl, and less depleted 18 O compositions. Samples belonging to this group are associated with groundwaters recharged locally, on a low ridge within the impact structure. This paper traces the probable source of high-F - groundwaters to phosphatic pellets in shales of the Winnipeg Formation, a regional basal clastic unit which sub-crops at shallow depth beneath the crater rim as a result of more than 200 m of structural uplift associated with the impact event. This extensive aquifer is known elsewhere in southern Manitoba for its naturally-softened groundwaters and locally elevated F - concentrations. Group I groundwaters are interpreted as discharge from the Winnipeg Formation where it abuts against crater-fill deposits.

    This report described a 3-month pilot project conducted by EnerGuide for Vehicles in collaboration with the Manitoba Motor Dealers Association (MMDA) to increase dealership and consumer awareness of vehicle impacts on climate change. The project also aimed to engage MMDA's members in helping to promote and distribute information on fuel efficient vehicles and fuel efficient driving habits. Program tools in both the dealership showroom as well as service areas were used. Objectives of the project also included gaining public opinion research (POR) information regarding the impact of program tools; gaining feedback from new car dealers regarding the success of the project; gauging customer perceptions of the importance of fuel efficiency when selecting a new vehicle; determining whether or not drivers verify tire pressure on their vehicles; determining whether or not drivers incorporate energy efficient driving habits; and gauging customer perceptions regarding the importance of incorporating behaviours to improve fuel efficiency. The study used a mixed methodology of online and telephone surveys. A total of 41 dealerships participated in the project. The final sample of surveys consisted of 1926 customer records. The total overall number of completed interviews was 463. Results indicated that most dealers believed the campaign was a success, and that staff and customers learned about energy efficiency as a result of the campaign. Seventy-five per cent of dealers agreed that they would participate in future energy efficiency programs. Campaign materials and customer incentives were widely viewed as successful in raising awareness. Seven in 10 dealership customers recalled at least 1 of the promotional endeavours, and a large majority of customers indicated the information they saw at the dealership encouraged them to consider fuel efficiency when buying or maintaining a vehicle in the future. The majority of new customers considered fuel consumption to be the second

  6. Kyoto and beyond : A plan of action to meet and exceed Manitoba's Kyoto targets

    International Nuclear Information System (INIS)

    2002-10-01

    This document represents the next step in Manitoba's effort to mitigate the effects of climate change. A message from the Manitoba Premier and the Minister of Conservation of Manitoba are included in the introduction. The Action Plan is based in part on the discussion among climate experts and public input gathered in the course of the 2001 task force and the 2001 public forum on climate change. A rise in average global temperatures is affecting most of the planet, which is due in part to the upsetting of the balance of greenhouse gases in the atmosphere as a result of human activities. It is affecting weather patterns, water, agriculture, forests, health and welfare, and life in the North. The Manitoba government is committed to meeting and exceeding the reduction targets set under the Kyoto Protocol through renewable electricity, Selkirk conversion, ethanol, methane capture, and other measures targeted toward industry. Energy efficiency also plays a big part in the process of reducing greenhouse gas emissions. The government is leading by example, and also investing in knowledge. It is promoting technology development and innovation while enhancing awareness and understanding. All sectors are being encouraged to implement appropriate measures. The various initiatives undertaken by each department and organization under each of those headings are described. figs

    Bajzak, D.; Bruneau, A.A.

    1987-01-01

    The short and long term effects of flooding on the environment, with special emphasis on trees, in the general area of the Churchill Falls hydroelectric project were investigated. A vegetation mapping and inventory was carried out in 1971, followed by the establishment of ground testlines in black spruce, white birch-balsam fir, and burnt (dead) black spruce stands at the rim of the main reservoir before the reservoir was filled in 1972. Additional field observations were made in 1973, 1974 and 1977. It was found that observed changes in the fluctuating water level zone were most significant. Both erosion of soils, mainly due to wave action, and vertical movement of the ice sheet during winter and the spring thaw, contribute to the uprooting of trees in the zone. Trees removed by the process float and under the action of wind and waves drift until trapped in standing trees or until driven ashore or onto dykes. Patches of accumulated driftwood in strips up to 20 m wide are not uncommon, and trees standing in water in protected coves or extensive shallows are not affected by soil erosion and deteriorate only due to fungal attack. 4 refs., 6 figs., 4 tabs

    1984-05-01

    The Shoal site is located in Churchill County in the northern part of the Sand Springs Range, approximately 30 miles (48.3 kilometers) southeast of Fallon, Nevada. Project Shoal, with a yield of 12 kilotons, was detonated October 26, 1963. It was conducted as part of the Vela program to obtain event measurements relating to the detection of underground nuclear detonations. The purpose of the Long-Term Hydrologic Monitoring Program at the Shoal site is to obtain data that will assure public safety; inform the public, the news media, and the scientific community relative to radiological contamination; and to document compliance with federal, state, and local antipollution requirements. The Shoal site geographical setting, climate, geology, and hydrology are described. Site history, including Shoal event information and Shoal monitoring is described. The final radiological surveys following the Shoal site cleanup described in this report indicate that there are no radiation levels above natural background on or near the land surface and that no hazard exists or is likely to occur during public use of the surface of the Shoal site. The Long-Term Hydrologic Monitoring Program for the Shoal site is described. 17 references, 4 figures

  11. Ethanol: the promise and the peril : Should Manitoba expand ethanol subsidies?

    International Nuclear Information System (INIS)

    Sopuck, R.D.

    2002-01-01

    Ethanol is produced through the fermentation of wheat. Blending ethanol with gasoline results in an ethanol-blended gasoline (EBG). Manitoba has already established an ethanol industry in the province and the government of the province is studying the feasibility of expansion. Every year in Manitoba, approximately 90 million litres of EBG are consumed, and the province's ethanol facility also produces a high protein cattle feed called distillers dry grain. Controversies surround the ethanol industry over both the economics and the environmental benefits and impacts. At issue is the economic efficiency of the production of ethanol, where opponents claim that the final product contains less energy than that required to produce it. A small gain is obtained, as revealed by a recent study. It is difficult to quantify the environmental effects of the ethanol industry, whether they be negative or positive. The author indicates that no matter what happens, the gasoline market in Manitoba is so small when compared to the rest of the world that the effect will not be significant. The three methods for the production of ethanol are: (1) the most risky and expensive method is the stand alone ethanol production facility, (2) integrated facilities where other products are produced, such as wet mash or nutraceuticals, and (3) integrated facilities where dry mash can be exported as a high protein feed. The production of a wide range of products is clearly the best option to be considered during the design of an ethanol facility. Price collapse and the capitalizing of subsidies into prices are the main risks facing the expansion of ethanol production in Manitoba. The author states that direct subsidies and price supports should be avoided, since subsidies would encourage the conversion of more feed grain into ethanol. The feed shortage would worsen especially as Manitoba does not currently produce enough feed to support its growing livestock industry. The author concludes that

    Nyboer, J.; Pape-Salmon, A.

    2003-05-01

    This first annual report on renewable energy in the Canadian electricity sector includes records from 629 power plants across Canada. Renewable energy sources include wind, hydroelectricity, wood residue biomass, landfill/sewage gas, solar photovoltaic, municipal solid waste, and tidal energy. The data in this report was acquired from Statistics Canada and other public information sources. For each of the 629 renewable energy power plants, this report states its type of renewable energy, the province, the name of the project, its location, its operator, electrical generating capacity, number of generating units, average annual electricity production, and the year it began operation. The majority (64 per cent) of Canada's total installed power capacity comes from renewable energy sources, with the dominant source being hydroelectricity. Manitoba has the highest portion of renewable energy at almost 98 per cent of its installed electrical capacity. Nearly half of Canada's renewable power capacity is in Quebec, followed by 18 per cent in British Columbia. Nova Scotia has Canada's only tidal power plant. Approximately 80 per cent of the total installed renewable energy power capacity in Canada is owned by integrated electric utilities. Eleven per cent is owned by renewable electricity generating companies, 5 per cent is owned by aluminium companies, and 3 per cent is owned by pulp and paper companies. The rest is owned by diversified electricity generators. It is expected that with the ratification of the Kyoto Protocol interest in renewable energy will grow. 6 refs., 3 tabs., 2 figs., 1 appendix

    Full Text Available Measurement of the impact and influence of medical/scientific journals, and of individual researchers has become more widely practiced in recent decades. This is driven, in part, by the increased availability of data regarding citations of research articles, and by increased competition for research funding. Digestive disease research has been identified as a particularly strong discipline in Canada. The authors collected quantitative data on the impact and influence of Canadian digestive health research. The present study involved an analysis of the research impact (Hirsch factor and research influence (Influence factor of 106 digestive health researchers in Canada. Rankings of the top 25 researchers on the basis of the two metrics were dominated by the larger research groups at the University of Toronto (Toronto, Ontario, McMaster University (Hamilton, Ontario, and the Universities of Calgary (Calgary, Alberta and Alberta (Edmonton, Alberta, but with representation by other research groups at the Universities of Manitoba (Winnipeg, Manitoba, Western Ontario (London, Ontario and McGill University (Montreal, Quebec. Female and male researchers had similar scores for the two metrics, as did basic scientists versus clinical investigators. Strategic recruitment, particularly of established investigators, can have a major impact on the ranking of research groups. Comparing these metrics over different time frames can provide insights into the vulnerabilities and strengths of research groups.

    Aimee L Schmidt

    2018-01-01

    Full Text Available Bear-inflicted human injuries or deaths are often widely publicised, controversial, and evoke substantial social responses that articulate public expectations about bear management. In this paper, we examine how local people and management agencies (i.e. Manitoba Conservation, Parks Canada, and the Town of Churchill responded to a polar bear-inflicted human injury in Churchill, Manitoba, Canada. On November 1st, 2013, two people in Churchill were badly mauled by a polar bear. The incident shocked the community, highlighted problems such as a lack of bear safety education, and led to reviews of institutional policies for preventing polar bear-human conflicts. We used qualitative analysis methods to describe what is said (about polar bears, about people, and about management and what is done (changes in behaviours and changes in policies/practices when someone is attacked by a polar bear in Churchill. Results show that polar bear management agencies in Churchill respond remarkably well to errors in procedure, but are often unable to address the many underlying systematic drivers of polar bear-human conflict. Hence, managerial reactions to bear-human conflicts are successful at addressing the proximate cause of the problem, but offer few long-term solutions.

  15. A Dutch Fanconi Anemia FANCC Founder Mutation in Canadian Manitoba Mennonites

    2012-01-01

    Full Text Available Fanconi anemia (FA is a recessive DNA instability disorder associated with developmental abnormalities, bone marrow failure, and a predisposition to cancer. Based on their sensitivity to DNA cross-linking agents, FA cells have been assigned to 15 complementation groups, and the associated genes have been identified. Founder mutations have been found in different FA genes in several populations. The majority of Dutch FA patients belongs to complementation group FA-C. Here, we report 15 patients of Dutch ancestry and a large Canadian Manitoba Mennonite kindred carrying the FANCC c.67delG mutation. Genealogical investigation into the ancestors of the Dutch patients shows that these ancestors lived in four distinct areas in The Netherlands. We also show that the Dutch and Manitoba Mennonite FANCC c.67delG patients share the same haplotype surrounding this mutation, indicating a common founder.

    1994-04-01

    The influence of referral protocols on the utilization of magnetic resonance imaging (MRI) services was studied. Three neuroradiologists and one radiologist reviewed the indications for MRI for 198 referrals to a facility in Winnipeg, selected at random from patients seen in 1991 for suspected disorders of the brain or the spine. Out-of-province referrals had not been subject to referral protocols, whereas those from within Manitoba had been subject to such protocols. At least three of the four radiologists agreed on whether an examination was appropriate in 88.4 % of the cases. Out-of-province referrals were significantly more likely to be considered inappropriate for MRI (24 %) than referrals from within Manitoba (10 %). It was estimated that the combined effect of instituting protocols and reviewing each referral before the examination could result in a 16 % to 31 % reduction in the demand for MRI services without compromising diagnostic information. 18 refs., 3 tabs.

  17. Geological controls on soil parent material geochemistry along a northern Manitoba-North Dakota transect

    2009-01-01

    As a pilot study for mapping the geochemistry of North American soils, samples were collected along two continental transects extending east-west from Virginia to California, and north-south from northern Manitoba to the US-Mexican border and subjected to geochemical and mineralogical analyses. For the northern Manitoba-North Dakota segment of the north-south transect, X-ray diffraction analysis and bivariate relations indicate that geochemical properties of soil parent materials may be interpreted in terms of minerals derived from Shield and clastic sedimentary bedrock, and carbonate sedimentary bedrock terranes. The elements Cu, Zn, Ni, Cr and Ti occur primarily in silicate minerals decomposed by aqua regia, likely phyllosilicates, that preferentially concentrate in clay-sized fractions; Cr and Ti also occur in minerals decomposed only by stronger acid. Physical glacial processes affecting the distribution and concentration of carbonate minerals are significant controls on the variation of trace metal background concentrations.

    Thomas, James M.; Lawrence, Stephen J.

    1994-01-01

    The U.S. Geological Survey investigated the quality of ground water in the Dayton, Stagecoach, and Churchill Valleys as part of the Carson River Basin National Water-Quality Assessment (NAWQA) pilot study. Four aquifer systems have been de- lineated in the study area. Principal aquifers are unconsolidated deposits at altitudes of less than 4,900 feet above sea level and more than 50 feet below land surface. Shallow aquifers are at altitudes of less than 4,900 feet and less than 50 feet below land surface. Upland aquifers are above 4,900 feet and provide recharge to the principal aquifers. Thermal aquifers, defined as those having a water temperature greater than 30 degrees Celsius, are also present. Ground water used in Dayton, Stagecoach, and Churchill Valleys is pumped from principal aquifers in unconsolidated basin-fill deposits. Ground water in these aquifers originates as precipitation in the adjacent mountains and is recharged by the Carson River and by underflow from adjacent upstream valleys. Ground-water flow is generally parallel to the direction of surface-water flow in the Carson River. Ground water is discharged by pumping, evapo- transpiration, and underflow into the Carson River. The results of geochemical modeling indicate that as ground water moves from upland aquifers in mountainous recharge areas to principal aquifers in basin-fill deposits, the following processes probably occur: (1) plagioclase feldspar, sodium chloride, gypsum (or pyrite), potassium feldspar, and biotite dissolve; (2) calcite precipitates; (3) kaolinite forms; (4) small amounts of calcium and magnesium in the water exchange for potassium on aquifer minerals; and (5) carbon dioxide is gained or lost. The geochemical models are consistent with (1) phases identified in basin- fill sediments; (2) chemical activity of major cations and silica; (3) saturation indices of calcite and amorphous silica; (4) phase relations for aluminosilicate minerals indicated by activity diagrams; and

  1. Churchill regulates cell movement and mesoderm specification by repressing Nodal signaling

    Directory of Open Access Journals (Sweden)

    Mentzer Laura

    2007-11-01

    Full Text Available Abstract Background Cell movements are essential to the determination of cell fates during development. The zinc-finger transcription factor, Churchill (ChCh has been proposed to regulate cell fate by regulating cell movements during gastrulation in the chick. However, the mechanism of action of ChCh is not understood. Results We demonstrate that ChCh acts to repress the response to Nodal-related signals in zebrafish. When ChCh function is abrogated the expression of mesodermal markers is enhanced while ectodermal markers are expressed at decreased levels. In cell transplant assays, we observed that ChCh-deficient cells are more motile than wild-type cells. When placed in wild-type hosts, ChCh-deficient cells often leave the epiblast, migrate to the germ ring and are later found in mesodermal structures. We demonstrate that both movement of ChCh-compromised cells to the germ ring and acquisition of mesodermal character depend on the ability of the donor cells to respond to Nodal signals. Blocking Nodal signaling in the donor cells at the levels of Oep, Alk receptors or Fast1 inhibited migration to the germ ring and mesodermal fate change in the donor cells. We also detect additional unusual movements of transplanted ChCh-deficient cells which suggests that movement and acquisition of mesodermal character can be uncoupled. Finally, we demonstrate that ChCh is required to limit the transcriptional response to Nodal. Conclusion These data establish a broad role for ChCh in regulating both cell movement and Nodal signaling during early zebrafish development. We show that chch is required to limit mesodermal gene expression, inhibit Nodal-dependant movement of presumptive ectodermal cells and repress the transcriptional response to Nodal signaling. These findings reveal a dynamic role for chch in regulating cell movement and fate during early development.

  2. Reconsidering 'Set the People Free': Neoliberalism and Freedom Rhetoric in Churchill's Conservative Party.

    Science.gov (United States)

    Freeman, James

    2017-09-18

    It is often assumed that 'Hayekian' or 'neoliberal' influences lay behind Conservative attacks on socialism in 1945 and subsequent calls to 'set the people free' in 1950 and 1951. This assumption has had consequences for our understanding of late-1940s Conservatism and for wider interpretations of post-war politics. Heeding recent calls to reconnect the inter-war and post-war parties and to pay closer attention to how opponents and contexts generate arguments, this article revisits senior Conservatives' rhetoric between 1945 and 1951 to break the link between neoliberal influence and freedom rhetoric. First, it argues that the rhetoric of 1945 was derived from a distinctly Conservative lineage of interwar argument and reflected strategies developed before the publication of F. A. Hayek's 'The Road to Serfdom'. Second, it demonstrates that senior Conservatives' emancipatory rhetoric in opposition after 1945 was neither a simple continuation of these themes nor primarily a response to the public's growing antipathy towards rationing and controls. Rather, such rhetoric was a complex response to Britain's immediate economic difficulties and the political challenges presented by austerity. Finally, the article sheds new light on the strategy that governed the party's campaigns in 1950 and 1951. Churchill and others' calls to 'set the people free' stemmed from a belief that the rhetorical opportunity lay in reconciling liberty with security. In that sense, the leadership had moved beyond begrudging compromises with the 'Attleean settlement' and was instead attempting to define a new identity within the parameters of the welfare state. © The Author [2017].

    This paper provides a comprehensive database of renewable energy facilities in Canada by province and by resource type. It considers technologies used for power generation or cogeneration, renewable energy heating systems, hydrogen generation and transportation fuels. Renewable energy technologies convert naturally regenerating resources into useful energy such as electricity, thermal energy, hydrogen or bio-fuels. The database contains information on renewable power operations in Canada over a scale of 100 kilowatts of rated capacity. Smaller applications have been included for run-of-river, hydro, earth, wind and solar power. There are 753 records for renewable energy facilities in Canada, including wind, hydroelectricity, wood residue biomass, landfill/sewage gas, solar photovoltaic, municipal solid waste, and tidal energy. The data in this report was acquired from Statistics Canada and other public information sources. For each of the 753 renewable energy power plants, this report states its type of renewable energy, the province, the name of the project, its location, its operator, electrical generating capacity, number of generating units, average annual electricity production, and the year it began operation. Canada currently has an installed electrical capacity of 115 GW, of which renewable energy sources constitute 76 per cent with the dominant source being hydroelectricity. Manitoba has the highest portion of renewable energy in its installed electrical capacity. Approximately 40 per cent Canada's renewable power capacity is in Quebec, followed by 15 per cent in British Columbia. Nova Scotia has Canada's only tidal power plant. Most of the installed renewable energy power capacity in Canada is owned by integrated electric utilities and a small percentage is owned by renewable electricity generating companies, aluminium companies, pulp and paper companies or diversified electricity generators. It is expected that interest in renewable energy will grow with

    1989-10-01

    An excavation response test was conducted in the Room 209 on the 240 m level of the AECL Underground Research Laboratory. Model predictions prior to excavation were made of the geomechanical response of the rock mass and the hydraulic response of an intercepted fracture. The model results were compared with excavation response data collected in a comprehensive instrument array. The work performed has addressed discrepancies between calculated and in-situ measured hydraulic response as part of a post-test analysis. Already existing hydraulic conceptual models of the fracture were revised and any available information was included in the new model. The model reproduced the pre-excavation hydraulic head distribution and hydraulic test results in terms of normalized flow rate within 5% and 75%, respectively. It was also found that the model reproduced the results of cross-hole hydraulic interference tests at least from a qualitative standpoint. The next stage of the modelling addressed the response of the model to a simulation of the excavated pilot tunnel. The preliminary results suggested the presence of a skin of different permeability in a thin zone around the periphery of the tunnel. By altering the permeability in the floor and along the walls and roof of the periphery, a better correspondence between calculated and measured drawdown was obtained. The same also applied for measured groundwater inflow in quantity, though not for the actual distribution on inflow. As probable causes for the interpreted positive skin in the crown and wall, temporary partial unsaturation and propulsion of debris into the fracture were suggested. The negative skin in the floor was interpreted as an effect of the dense and high energy charges used in the excavation process. (authors)

    2010-01-01

    Climate change is likely to affect extreme flows as well as average flows. This is an important consideration for hydroelectric power producers. This paper presented the development of an approach to assess the impact of climate changes on seasonal and average annual river flows. The main goal was to investigate how climate change will affect the hydroelectric potential of the Lower Churchill Project using different combinations of emissions scenarios, climate model output and downscaling techniques. The setup and calibration of the numerical hydrological model, WATFLOOD, were performed as preliminary work for the Pinus River basin selected as study basin. Downscaled climate data from the North America change assessment program for both current and future climate periods were analysed. The calibrated model was used to simulate the current and future period streamflow scenarios. The results showed a 13 percent increase in mean annual flows concentrated in the winter and spring seasons.

    Climate change is likely to affect extreme flows as well as average flows. This is an important consideration for hydroelectric power producers. This paper presented the development of an approach to assess the impact of climate changes on seasonal and average annual river flows. The main goal was to investigate how climate change will affect the hydroelectric potential of the Lower Churchill Project using different combinations of emissions scenarios, climate model output and downscaling techniques. The setup and calibration of the numerical hydrological model, WATFLOOD, were performed as preliminary work for the Pinus River basin selected as study basin. Downscaled climate data from the North America change assessment program for both current and future climate periods were analysed. The calibrated model was used to simulate the current and future period streamflow scenarios. The results showed a 13 percent increase in mean annual flows concentrated in the winter and spring seasons.

    This paper will review Winston Churchill's severe respiratory illness in March 1886 when he developed pneumonia of the right lung as an 11-year-old boy. Winston was treated supportively with 'nourishment, stimulants [probably alcohol] and close watching' at his school by the 'celebrated' family physician, Dr Robson Roose, with the assistance of Dr Joseph Rutter. Roose was exemplary in his commitment to his young patient and assiduous in informing Lord Randolph Churchill of his son's clinical progress by letter.

    In 2003, six ice cores measuring 10.5, 11.5, 11.8, 12.4, 114 and 460 meters were recovered from the col between Mount Bona and Mount Churchill (61° 24'N; 141° 42'W; 4420 m asl). These cores have been analyzed for stable isotopic ratios, insoluble dust content and concentrations of major chemical species. Total Beta radioactivity was measured in the upper sections. The 460-meter core, extending to bedrock, captured the entire depositional record at this site where ice temperatures ranged from -24° C at 10 meters to -19.8° C at the ice/bedrock contact. The shallow cores allow assessment of surface processes under modern meteorological conditions while the deep core offers a ˜1500-year climate and environmental perspective. The average annual net balance is ˜~1000 mm of water equivalent and distinct annual signals in dust and calcium concentrations along with δ 18O allow annual resolution over most of the core. The excess sulfate record reflects many known large volcanic eruptions such as Katmai, Krakatau, Tambora, and Laki which allow validation of the time scale in the upper part of the core. The lower part of the core yields a history of earlier volcanic events. The 460-m Bona-Churchill ice core provides a detailed history of the `Little Ice Age' and medieval warm periods for southeastern Alaska. The source of the White River Ash will be discussed in light of the evidence from this core. The 460-m core also provides a long-term history of the dust fall that originates in north-central China. The annual ice core-derived climate records from southeastern Alaska will facilitate an investigation of the likelihood that the high resolution 1500-year record from the tropical Quelccaya Ice Cap (Peru) preserves a history of the variability of both the PDO and the Aleutian Low.

    2008-01-01

    As part of the licensing process to construct a new 230 kV transmission line on an existing right-of-way in Manitoba, an electrical effects study was conducted in 1998. The study was part of the environmental assessment program crucial in obtaining government approval to construct the line. Some residents living adjacent to the new transmission circuit expressed concerns about alleged adverse health effects associated with long-term exposure to magnetic fields from high voltage transmission lines. In order to verify the accuracy of the predicted magnetic field levels submitted to the regulatory body in the the electrical effects study and to instill confidence in the residents of the affected communities, a three-year magnetic monitoring project was conducted between 2003 and 2005 along the right-of-way after the new 230kV transmission line was energized by Manitoba Hydro. This paper described the monitoring program, with reference to location; equipment; data analysis; and discussion of results. It was concluded that the long-term monitoring project demonstrated that the magnetic field prediction methodology was well understood and accurate, and provided valuable long-term magnetic field characteristics at the edge of the right-of-way. In addition, when there is opposition to a transmission line, public consultation and education were found to be the best options to arrive at a solution. 3 refs., 1 tab., 12 figs

    Rural recruitment and retention continues to present challenges to health workforce planners. This paper reports and analyzes the results of a survey sent to physicians in Manitoba, eliciting their opinions regarding rural jobs. A survey was sent to all physicians in Manitoba. Part 1 of the survey included questions about background and demographic information; part 2 was a set of job satisfaction questions regarding respondents' current job; and part 3 included 2 sets of stated-choice questions eliciting preferences for a set of attributes relevant to rural recruitment and retention. Of the 2487 physicians who received surveys, 561 (22.6%) responded. Respondents indicated that income, hours worked and on-call frequency are very important: overall job satisfaction increased with income and decreased with hours worked. Income, hours and on-call frequency were ranked "very important" by the largest proportions of physicians. The estimated compensation for on-call more frequent than 1-in-4 was very high (82% of average income), and additional hours worked were worth $183 per hour. Other attributes that were important included professional interaction, housing availability and community incentives during the first year, which were valued at 11%-31% of annual income. Work-life balance is a key consideration for rural jobs, and there are incentives that can compensate for less desirable attributes.

    Although the interfacility transport (IFT) of critically ill pediatric patients from rural to tertiary health centres may improve outcomes, the impact of IFTs on the rural referring centre is not known. The purpose of this study was to investigate how the IFT of critically ill children affects staffing and functionality of rural emergency departments (EDs) in Manitoba. In 2015, surveys were emailed to the medical directors of all 15 regional EDs within 2 hours' travel time from a tertiary pediatric hospital. The survey consisted of 9 questions that addressed baseline characteristics of the regional EDs and duration of ED staffing changes or closures due to IFT of critically ill pediatric patients. Ten surveys were received (67% response rate); a regional ED catchment population of about 130 000 people was represented. Interfacility transport caused most EDs (60%, with an average catchment population of 15 000) to close or to alter their staffing to a registered nurse only. These temporary changes lasted a cumulative total of 115 hours. Interfacility transport of critically ill pediatric patients resulted in ED closures and staffing changes in rural Manitoba. These findings suggest that long-term sustainable solutions are required to improve access to emergency care.

    Despite the existence of the slow-moving vehicle (SMV) emblem for almost 50 years, there continues to be a large number of preventable accidents between SMVs and other motorists. In this study, the current SMV emblem was tested against other common road signs as well as alternative slow-moving vehicle emblems to determine motorist comprehension of the signs. An open-ended test method was used to determine the level of comprehension by Manitoba motorists. Written answers from 50 participants were classified as either "correct" or "incorrect" by the authors based on the meaning of the traffic signs provided in a driver's handbook. Only 3 of the 16 Manitoba traffic signs attained the 85% level of comprehension required by ANSI standards. Only 22% of participants correctly identified the current SMV emblem. Two alternatives to the SMV emblem found in the literature, both iconic in nature, were understood to mean "slow-moving vehicle" by only 2% and 8% of participants, respectively. Two alternatives to the SMV developed for this project were evaluated with levels of comprehension of 68% and 84%: however, these levels of comprehension were likely biased by the presence of text. There is insufficient evidence to suggest that the current symbolic SMV emblem should be replaced by an alternative emblem that is iconic in nature.

    1977-01-01

    A pilot program carried out in Western Canada to test remote sensing under semi-operational conditions and display its applicability to operational range management programs was described. Four agencies were involved in the program, two in Alberta and two in Manitoba. Each had different objectives and needs for remote sensing within its range management programs, and each was generally unfamiliar with remote sensing techniques and their applications. Personnel with experience and expertise in the remote sensing and range management fields worked with the agency personnel through every phase of the pilot program. Results indicate that these agencies have found remote sensing to be a cost effective tool and will begin to utilize remote sensing in their operational work during ensuing seasons.

    Full Text Available I examined the relationships among snow cover (api, lichen abundance, and canopy composition on the range of the Aikens Lake population of woodland caribou (Rangifer tarandus caribou in southeastern Manitoba. Percent cover of forage lichens (Cladina spp. was positively correlated with maximum total thickness and with maximum vertical hardness of api. Mixed communities of trembling aspen (Populus tremuloides, spruce (Picea spp., and balsam fir (Abies balsamea showed the most favourable nival conditions for caribou but had low lichen abundance; those dominated by jack pine (Pinus banksiana were the converse. The results suggest an energetic compromise for woodland caribou when foraging for terrestrial lichens. During winter, caribou exhibited significant selection for jack pine communities whereas mixed communities were avoided.

    As a pilot study for mapping the geochemistry of North American soils, samples were collected along two continental transects extending east–west from Virginia to California, and north–south from northern Manitoba to the US–Mexican border and subjected to geochemical and mineralogical analyses. For the northern Manitoba–North Dakota segment of the north–south transect, X-ray diffraction analysis and bivariate relations indicate that geochemical properties of soil parent materials may be interpreted in terms of minerals derived from Shield and clastic sedimentary bedrock, and carbonate sedimentary bedrock terranes. The elements Cu, Zn, Ni, Cr and Ti occur primarily in silicate minerals decomposed by aqua regia, likely phyllosilicates, that preferentially concentrate in clay-sized fractions; Cr and Ti also occur in minerals decomposed only by stronger acid. Physical glacial processes affecting the distribution and concentration of carbonate minerals are significant controls on the variation of trace metal background concentrations.

  2. The Manitoba-Ontario intertie : perspectives of a merchant transmission developer

    International Nuclear Information System (INIS)

    Van Beers, R.

    2006-01-01

    This presentation discussed merchant transmission models for the Manitoba-Ontario intertie. Merchant transmission involves the reallocation of risk from rate payers to investors and facility users. Merchant transmission is now a niche market due to the fact that the power industry is now more centrally planned. However, merchant transmission structures limit the ability to fully assess congestion and nodal values, and governments continue to retain control of the power sector. Power generation and contracting trends are now changing as a result of market liberalization. In order to be successful, power merchants require financial markets that possess an understanding of the electricity sector. In a merchant transmission scenario, the sizing, timing, connection points, and tariffs will be determined by demonstrated commercial value, and not by central planning principles. The presentation included consideration of government block contracts and reverse block contracts. Details of the Montana-Alberta intertie project were also provided. tabs., figs

    Electric power in Canada was first generated by steam in the 1880s. The use of hydroelectricity spread rapidly due to abundant water resources and the nationalization of power companies by the provinces; by 1920, 97% of Canadian electricity production came from hydroelectric plants. Thermal generation became competitive by the 1960s, when most of the best hydro sites had been developed, and nuclear generation also started gaining a share of the market. By 1991, hydroelectricity's share of Canadian power production had declined to around 60%. Hydroelectric power has long been used as an instrument of Canadian industrial policy. Given the amount and importance of utility capital expenditures, it was recognized that hydropower development could serve such policy objectives as job creation, industrial development, and macroeconomic stabilization. Creation of provincially owned utilities led to construction of large hydroelectric projects, notably in Quebec, British Columbia, Manitoba, and Newfoundland. The 20 largest hydroelectric power plants in Canada have a total installed capacity of 35,704 MW, representing ca 59% of Canada's total 1991 hydro capacity. The construction of such large projects is not expected to proceed as quickly as in the past because of environmental concerns. However, a number of factors favor continuation of development of hydro resources: a remaining potential estimated at ca 44,000 MW; simplification of electricity export regulations; more stringent air pollution standards that favor non-polluting energy sources; and a moratorium on nuclear power plants in Ontario. 4 tabs

    To summarize seven years of surveillance data for Lyme disease cases reported in Canada from 2009 to 2015. We describe the incidence over time, seasonal and geographic distribution, demographic and clinical characteristics of reported Lyme disease cases. Logistic regression was used to explore differences between age groups, sex and year to better understand potential demographic risk factors for the occurrence of Lyme disease. The number of reported Lyme disease cases increased more than six-fold, from 144 in 2009 to 917 in 2015, mainly due to an increase in infections acquired in Canada. Most locally acquired cases were reported between May and November. An increase in incidence of Lyme disease was observed in provinces from Manitoba eastwards. This is consistent with our knowledge of range expansion of the tick vectors in this region. In the western provinces the incidence has remained low and stable. All cases reported by Alberta, Saskatchewan and Newfoundland and Labrador were acquired outside of the province, either elsewhere in Canada or abroad. There was a bimodal distribution for Lyme disease by age with peaks at 5-9 and 45-74 years of age. The most common presenting symptom was a single erythema migrans rash (74.2%) and arthritis (35.7%). Variations in the frequency of reported clinical manifestations were observed among age groups and years of study. Lyme disease incidence continues to increase in Canada as does the geographic range of ticks that carry the Lyme disease bacteria. Ongoing surveillance, preventive strategies as well as early disease recognition and treatment will continue to minimize the impact of Lyme disease in Canada.

    This report summarizes the drilling program conducted by the U.S. Department of Energy (DOE) Office of Legacy Management at the Project Shoal Area (Shoal) Subsurface Corrective Action Unit 447 in Churchill County, Nevada. Shoal was the location of an underground nuclear test conducted on October 26, 1963, as part of the Vela Uniform program sponsored jointly by the U.S. Department of Defense and the U.S. Atomic Energy Commission (a predecessor to DOE). The test consisted of detonating a 12-kiloton nuclear device in granitic rock at a depth of approximately 1,211 feet (ft) below ground surface (bgs) (AEC 1964). The corrective action strategy for the site is focused on revising the site conceptual model and evaluating the adequacy of the monitoring well network at the site. Field activities associated with the project were conducted in accordance with the Federal Facility Agreement and Consent Order (FFACO 1996, as amended) and applicable Nevada Division of Environmental Protection (NDEP) policies and regulations.

    This report presented a strategy and a set of recommendations for the adoption, development and implementation of an energy code for new commercial construction in Manitoba. The report was compiled by an advisory committee comprised of industry representatives and government agency representatives. Recommendations were divided into 4 categories: (1) advisory committee recommendations; (2) code adoption recommendations; (3) code development recommendations; and (4) code implementation recommendations. It was suggested that Manitoba should adopt an amended version of the Model National Energy Code for Buildings (1997) as a regulation under the Buildings and Mobile Homes Act. Participation in a national initiative to update the Model National Energy Code for Buildings was also advised. It was suggested that the energy code should be considered as the first step in a longer-term process towards a sustainable commercial building code. However, the code should be adopted within the context of a complete market transformation approach. Other recommendations included: the establishment of a multi-stakeholder energy code task group; the provision of information and technical resources to help build industry capacity; the establishment of a process for energy code compliance; and an ongoing review of the energy code to assess impacts and progress. Supplemental recommendations for future discussion included the need for integrated design by building design teams in Manitoba; the development of a program to provide technical assistance to building design teams; and collaboration between post-secondary institutions to develop and deliver courses on integrated building design to students and professionals. 17 refs.

    Farias, A. R.

    1999-01-01

    Development of an of an Ice Storm Management program by Manitoba Hydro to reduce ice storm damage to its 8 kV feeders to 115 kV transmission lines, is discussed. The program consists of the de-icing of overhead lines, either by ice melting, or ice rolling. Ice melting involves the placement of a three-phase short at a calculated point. The term ice rolling denotes a process of mechanically stripping the ice from conductors. The most recent major ice storm experienced by Manitoba Hydro was in the winter of 1997/1998. During the period from February 6 to February 17, 1998, a total of 83 'ice melt' procedures were performed to melt the ice from 2,628 km of overhead line (7,883 km of conductor), in addition to 'ice rolling'. This paper describes Manitoba Hydro's 25-years' experience with ice melting and it also describes the advantages and disadvantages of both ice melting and ice rolling. Although not a panacea to combat the effects of ice storms, ice melting was found to be the most effective way of removing ice from overhead transmission and sub-transmission lines. Ice rolling was also found to be effective. Other tools that have been found to be useful by various utilities in combating ice storm damage include improved structure and line design, system design that provide more redundancies and emergency sources, and standby generators at critical load points

    Ontario may have an electrical power shortfall of as much as 25,000 MW by 2020, due to phase-out of coal fired plants, a general increase in demand and existing plants reaching the end of their design lives. Manitoba has approximately 5,000 MW of new hydroelectric power potential which could help to reduce this shortfall. This document reports on a study between the Manitoba government, the Ontario government, Manitoba Hydro, Hydro One, and the Ontario Independent Electricity Market Operator to provide an incremental transfer capability of 1,500 MW between the provinces. This is known as the Clean Energy Transfer Initiative (CETI). The current east-west transmission grid is limited to about 200 MW and is thus not sufficient for this project. Three transmission options have been studied. The report claims that CETI would be the largest single project in terms of greenhouse gas reductions. It is also claimed to potentially benefit Aboriginal groups by increasing employment and business opportunities. Also, tax revenues would be substantial. The most likely alternative energy supply is considered to be the combined cycle gas turbine which, according to the study, would cost about the same amount per MWh, excluding environmental credits. 4 tabs., 11 figs.

    Ultramylonitic shear zones typically involve intense strain localization, and when developed over large regions can introduce considerable heterogeneity into the crust. The Cora Lake shear zone (CLsz) displays several 10's to 100's of meters-wide zones of ultramylonite distributed throughout its full 3-5 km mylonitized width. Detailed mapping, petrography, thermobarometry, and in-situ monazite geochronology suggest that it formed during the waning phases of granulite grade metamorphism and deformation, within one of North America's largest exposures of polydeformed lower continental crust. Anastomosing zones of ultramylonite contain recrystallized grain-sizes approaching the micron scale and might appear to suggest lower temperature mylonitization. However, feldspar and even clinopyroxene are dynamically recrystallized, and quantitative thermobarometry of syn-deformational assemblages indicate high P and T conditions ranging from 0.9 -10.6 GPa and 775-850 °C. Even at these high T's, dynamic recovery and recrystallization were extremely limited. Rocks with low modal quartz have extremely small equilibrium volumes. This is likely the result of inefficient diffusion, which is further supported by the unannealed nature of the crystals. Local carbonate veins suggests that H2O poor, CO2 rich conditions may have aided in the preservation of fine grain sizes, and may have inhibited dynamic recovery and recrystallization. The Cora Lake shear zone is interpreted to have been relatively strong and to have hardened during progressive deformation. Garnet is commonly fractured perpendicular to host rock fabric, and statically replaced by both biotite and muscovite. Pseudotachylite, with the same sense of shear, occurs in several ultramylonitized mafic granulites. Thus, cataclasis and frictional melt are interpreted to have been produced in the lower continental crust, not during later reactivation. We suggest that strengthening of rheologically stiffer lithologies led to extreme localization, and potentially earthquakes in quartz-absent hardened lithologies. Cora Lake shearing represents the culmination of a deformation trend of increasing strength, strain partitioning, and localization within a polydeformed, strengthened lower continental crust.

  16. Canada, a big energy consumer : a regional perspective : analysis in brief

    Menard, M.

    2005-01-01

    Canada's energy consumption in 2002 ranked almost equal to that of the United States. This high energy consumption can be attributed to long winters, long travel distances and an economy based on high energy consuming industries such as mining, forestry, petrochemical, pulp and paper, aluminium smelters, refining and steel manufacturing. This report describes the energy consumption in various regions of Canada between 1990 and 2003, a time in which total energy consumption increased by 23 per cent. This increase in energy was compared to variations in population and economic activity. The largest increase in energy consumption occurred in Alberta due to a surge in population and economic expansion in high energy consuming industries such as the petroleum and oil sands industry. Saskatchewan had the second-highest increase in energy consumption followed by Quebec, Ontario and British Columbia. The lowest increase in energy consumption was in the northern region and Manitoba. Canada has made a commitment to the Kyoto Protocol to reduce greenhouse gas emissions by 6 per cent. As a large consumer of energy from non-renewable energy resources, Canada is looking into substituting energy types that emit fewer greenhouse gases in order to meet this target. The report revealed that Canada's energy profile is not the same across the country and varies in terms of economy, weather, geography, geology and energy sources. refs., tabs., figs

  17. Water-level changes and directions of ground-water flow in the shallow aquifer, Fallon area, Churchill County, Nevada

    The Truckee-Carson-Pyramid Lake Water Rights Settlement Act of 1990 directed the U.S. Fish and Wildlife Service to acquire water rights for wetland areas in the Carson Desert, Nevada. The public is concerned that htis acquisition of water rights and delivery of the water directly to wildlife areas would result in less recharge to the shallow ground water in the Fallon area and cause domestic wells to go dry. In January 1992, the U.S. Geological Survey, in cooperation with U.S. Fish and Wildlife Service, began a study of the shallow ground-water system in the Fallon area in Churchill County, Nevada. A network of 126 wells in the study area was monitored. Between January and November 1992, water levels in most wells declined, usually less than 2 feet. The maximum measured decline over this period was 2.68 feet in a well near Stillwater Marsh. Between April and July, however, water levels rose in irrigated areas, typically 1 to 2 feet. Newlands Project water deliveries to the study area began soon after the turn of the century. Since then, water levels have risen more than 15 feet across much of the study area. Water lost from unlined irrigtiaon canals caused the stage in Big Soda Lake to rise nearly 60 feet; ground-water levels near the lake have risen 30 to 40 feet. The depth to water in most irrigated areas is now less than 10 feet. The altitude of the water table ranges from 4.025 feet above sea level 11 miles west of Fallon to 3,865 feet in the Stillwater Marsh area. Ground water flows eastward and divides; some flow goes to the northeast toward the Carson Sink and Stillwater areas, and some goes southeastward to Carson Lake.

    1995-09-01

    This review examines isotopic methods used to determine groundwater sources, residence times and processes of geochemical evolution that have been published in the international literature, with specific reference to AECL's experience in these methods and applications to groundwaters at the Underground Research Laboratory (URL), Manitoba. The program of groundwater sampling and analysis currently being planned for the URL area over the next several years will concentrate on specific isotopic measurements that may assist in understanding the groundwater flow system at the URL site. These results will add to the existing data for the URL area and indicate which isotopes are most useful when applied to the known groundwater flow system of the URL. This program of study is especially important because it not only uses standard geochemical and isotopic measurements (e.g., major ion, trace elements, 2 H/ 18 O, 14 C, 34 S) of groundwaters, but will determine values of more exotic and unusual ratios, such as 6 Li/ 7 Li, and B 11 /B 10 , whose potential for understanding groundwater geochemical evolution is largely unknown at present. In addition, the more established but equally complex methods of isotopic analysis, to determine 3 He/ 4 He, 36 Cl/Cl and 129 I/I, will be used to assess their potential for adding to the hydrogeochemical understanding of flow paths in crystalline rock.

    Hryhoruk, C.D.

    1994-01-01

    At a northern Manitoba airport, a site was contaminated with diesel fuel, which was confined within the unsaturated zone in silt and silty sand. A two-phase bioremediation process was designed and implemented in-situ in a pilot test. The first phase, ground surface spraying, involved mixing nutrients (ammonium-nitrogen and orthophosphate) with water in a tank and then spraying the mixture on the ground surface above the diesel plume. The second phase, a pump-cycle system, involved pumping groundwater from below the diesel plume into one of two tanks in series. The groundwater underwent both nutrient addition (weekly) and aeration in the tanks, then it was pumped into eight feeder wells which circumscribed an extraction well. Soil testing revealed that both remediation processes aided in increasing subsurface nutrient concentrations and the moisture content within the diesel plume. In addition, high total coliform counts were observed in both the silt and silty sand layers. This implied that conditions for suitable bioremediation can be developed in relatively fine-grained soil. Intermittent soil sampling at three locations over a 14-month period revealed that the diesel plume decreased in size by ca 30% and contaminant concentrations (diesel fuel) also decreased. Plume movement also occurred. The pump-cycle system remains operational. 67 refs., 77 figs., 9 tabs

    1980-01-01

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

    Full Text Available Objectives – This study examines the use of print and electronic collections bothbefore and after implementation of Summon at the University of Manitoba Libraries.Summon is a web-scale discovery service which allows discovery of all of thematerials the library owns or has access to from a simple search box on the library’sweb page.Methods – COUNTER statistics were used to determine database, e-journal, and ebookstatistics, including database search statistics (DR1 from the COUNTERDatabase Report 1, full-text article downloads from the COUNTER Journal Report 1(JR1, and successful section search requests from the COUNTER Book Report 2 (BR2for electronic resources. Sirsi, the University of Manitoba’s integrated library system,provided statistics on checkouts for the libraries’ circulating print monograph andserial collections. The percentage change from the pre-Summon implementationperiod to the post-Summon implementation period was calculated and these numberswere used to determine whether usage had increased or decreased for both print andelectronic collections.Results – As expected, searches in citation databases decreased because searches wereno longer being carried out in the native database as the metadata from the databaseis included in Summon. E-journal usage increased dramatically and e-book usage alsoincreased for four of six providers examined. Print usage decreased, but the resultswere inconclusive.Conclusions – Summon implementation had a favourable impact on collection usage.

    The Green Building Challenge (GBC) in Canada was launched to help the building community meet environmental challenges and improve the environmental performance of buildings. Tools have been made available to the building industry to make informed environmental choices during the conception design stage of a project. The tools help architects, researchers and policy analysts in choosing material mixes and other design options that will minimize a building's potential life cycle environmental impacts and promote sustainable development. Green buildings involve the complete structure and envelope, including cladding, insulation, gypsum wall board, roofing and windows. The type of building and its location is also considered. Long term sustainability also considers energy use and emissions related to a building's energy system. This presentation described the following 3 projects which were selected for assessment in the GBC-2002: (1) the Mayo School in Mayo, Yukon Territory, (2) the Jackson-Triggs Winery in Niagara-on-the-Lake, Ontario, and (3) the Red River College in Winnipeg, Manitoba. The GBC-2002 Canadian Team nominated them as the best buildings being designed in Canada.10 figs.

    Canada's fusion strategy is based on developing specialized technologies in well-defined areas and supplying these technologies to international fusion projects. Two areas are specially emphasized in Canada: engineered fusion system technologies, and specific magnetic confinement and materials studies. The Canadian Fusion Fuels Technology Project focuses on the first of these areas. It tritium and fusion reactor fuel systems, remote maintenance and related safety studies. In the second area, the Centre Canadian de fusion magnetique operates the Tokamak de Varennes, the main magnetic fusion device in Canada. Both projects are partnerships linking the Government of Canada, represented by Atomic Energy of Canada Limited, and provincial governments, electrical utilities, universities and industry. Canada's program has extensive international links, through which it collaborates with the major world fusion programs, including participation in the International Thermonuclear Experimental Reactor project

    Single-hole borehole-radar reflection logs were collected and interpreted in support of a study to characterize ground-water flow and transport at the Project Shoal Area (PSA) in Churchill County, Nevada. Radar logging was conducted in six boreholes using 60-MHz omni-directional electric-dipole antennas and a 60-MHz magnetic-dipole directional receiving antenna. Radar data from five boreholes were interpreted to identify the location, orientation, estimated length, and spatial continuity of planar reflectors present in the logs. The overall quality of the radar data is marginal and ranges from very poor to good. Twenty-seven reflectors were interpreted from the directional radar reflection logs. Although the range of orientation interpreted for the reflectors is large, a significant number of reflectors strike northeast-southwest and east-west to slightly northwest-southeast. Reflectors are moderate to steeply dipping and reflector length ranged from less than 7 m to more than 133 m. Qualitative scores were assigned to each reflector to provide a sense of the spatial continuity of the reflector and the characteristics of the field data relative to an ideal planar reflector (orientation score). The overall orientation scores are low, which reflects the general data quality, but also indicates that the properties of most reflectors depart from the ideal planar case. The low scores are consistent with reflections from fracture zones that contain numerous, closely spaced, sub-parallel fractures. Interpretation of borehole-radar direct-wave velocity and amplitude logs identified several characteristics of the logged boreholes: (1) low-velocity zones correlate with decreased direct-wave amplitude, indicating the presence of fracture zones; (2) direct-wave amplitude increases with depth in three of the boreholes, suggesting an increase in electrical resistivity with depth resulting from changes in mineral assemblage or from a decrease in the specific conductance of ground

    Two species of the genus Cladotanytarsus Kieffer, 1921 are described as adult males, both peculiar in having distinctively elongated hypopygial anal points. The male of Cladotanytarsus bilyji Giłka et Puchalski, sp. nov. (Canada, Manitoba; USA, Ohio) is presumed to be a close relative of C. nigrovittatus (Goetghebuer, 1922). Another unknown Cladotanytarsus species (USA, Illinois and Louisiana) keys with the European C. donmcbeani Langton et McBean, 2010. The intraspecific variability of the male C. acornutus Jacobsen et Bilyj, 2007 is also presented on the basis of new records (Canada, Ontario; USA, South Carolina). Cladotanytarsus males with similarly structured elongate anal points are reviewed, including C. tobaquardecimus Kikuchi et Sasa, 1990, considered a junior synonym (syn. nov.) of C. conversus (Johannsen, 1932). As a compilation of this study, a key to the identification of the adult males of 14 Cladotanytarsus species is provided.

    2018-01-22

    Fatal accidents often lead to policy changes. However, the existing decision-making environment is critical to policy responses. This study compares the policy responses to similar events in Manitoba and Saskatchewan. The key question explores the extent to which the policy decisions in each province differ despite the similarity of the events. Key documents were examined. Provincial court rulings, workplace health & safety incident investigation reports, court transcripts and police reports were used to compare resulting policy changes as well as the socio-political and economic decision-making context. Relevant clauses in resulting legislation were also compared to assess the specific changes that were made in each province. In each province, a young, female highway construction worker was killed. However, the provinces responded in very different ways. In Saskatchewan, the Premier called for recommendations to improve worker safety, initiating an in-depth governmental study and the development of a broad safety strategy. In Manitoba, political and social pressures shifted the decision-making environment and contributed to the rushed passing of a bill focused on traffic fine increases that resulted in record-breaking traffic fine revenue while failing to include broader safety measures. Different decision-making contexts can lead to vastly different policy outcomes even when responding to very similar events. Key differences included time constraints, access to information and the nature of the political process invoked.

    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.

    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)

    Full Text Available The organization of Canada’s provincial health care systems and the administrative databases that sustain them provide physicians, epidemiologists and public health officials with unique opportunities to improve surveillance of influenza and its prevention. These databases can be used to measure the impact of influenza on excess mortality, hospitalization and costs to the health care system. They can also be used to study the epidemiology of influenza vaccination practices. Studies using the administrative database for the province of Manitoba have established the epidemiological rationale for hospital-based vaccination and have evaluated the clinical effectiveness of influenza vaccination. As pneumococcal vaccination becomes widespread in Canada, provincial databases should also prove useful in assessing the impact of the pneumococcal infections and their prevention with pneumococcal vaccine.

    Atomic Energy of Canada Limited (AECL) is constructing an Underground Research Laboratory (URL) to a depth of 250 m in a previously undisturbed granitic pluton located near Lac du Bonnet, Manitoba, as one of the major research projects within the Canadian Nuclear Fuel Waste Management Program. This paper discusses the hydrogeological characterization of the URL site, the modelling approach used to represent this information, the hydrogeological monitoring system installed to monitor the actual drawdown conditions that develop in response to the excavation, and the procedures employed to calibrate the numerical model. Comparisons between the drawdown predictions made by the model prior to any excavation and the actual drawdowns that have been measured since shaft excavation began in May 1984 are also discussed

    Wildland fires are the main natural disturbance shaping forest structure and composition in eastern boreal Canada. On average, more than 700 000 ha of forest burns annually and causes as much as CAD 2.9 million worth of damage. Although we know that occurrence of fires depends upon the coincidence of favourable conditions for fire ignition, propagation, and fuel availability, the interplay between these three drivers in shaping spatiotemporal patterns of fires in eastern Canada remains to be evaluated. The goal of this study was to reconstruct the spatiotemporal patterns of fire activity during the last century in eastern Canada's boreal forest as a function of changes in lightning ignition, climate, and vegetation. We addressed this objective using the dynamic global vegetation model LPJ-LMfire, which we parametrized for four plant functional types (PFTs) that correspond to the prevalent tree genera in eastern boreal Canada (Picea, Abies, Pinus, Populus). LPJ-LMfire was run with a monthly time step from 1901 to 2012 on a 10 km2 resolution grid covering the boreal forest from Manitoba to Newfoundland. Outputs of LPJ-LMfire were analyzed in terms of fire frequency, net primary productivity (NPP), and aboveground biomass. The predictive skills of LPJ-LMfire were examined by comparing our simulations of annual burn rates and biomass with independent data sets. The simulation adequately reproduced the latitudinal gradient in fire frequency in Manitoba and the longitudinal gradient from Manitoba towards southern Ontario, as well as the temporal patterns present in independent fire histories. However, the simulation led to the underestimation and overestimation of fire frequency at both the northern and southern limits of the boreal forest in Québec. The general pattern of simulated total tree biomass also agreed well with observations, with the notable exception of overestimated biomass at the northern treeline, mainly for PFT Picea. In these northern areas, the

    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)

    A significant barrier to accessing healthcare in Canada is long waiting lists, which can be linked to the way that Medicare was structured. After significant pressure, provincial governments began to address wait times. An example of a successful strategy to reduce wait times for elective surgery is the Saskatchewan Surgical Initiative, which saw wait times in the province change from being among the longest in Canada to the shortest.

    In July 1990, Greenpeace distributed a 16-page treatise entitled 'Canada's Radiation Scandal' to a wide audience. The bottom line of the Greenpeace critique was that 'Canada's radiation limits are among the worst in the developed world'. This is a commentary on the Greenpeace pamphlet from the Atomic Energy Control Board (AECB), the body that sets and enforces radiation standards covering the use of nuclear energy in Canadian industry, science and medicine

  10. 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

    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.

    Echinococcus species are important parasites of wildlife, domestic animals and people worldwide; however, little is known about the prevalence, intensity and genetic diversity of Echinococcus tapeworms in Canadian wildlife. Echinococcus tapeworms were harvested from the intestines of 42% of 93 wolves (Canis lupus) from five sampling regions in the Northwest Territories, Manitoba and Saskatchewan, and visually identified to genus level by microscopic examination. Genetic characterization was successful for tapeworms from 30 wolves, and identified both Echinococcus canadensis and Echinococcus multilocularis in all sampling locations. Mixed infections of E. canadensis/E. multilocularis, as well as the G8/G10 genotypes of E. canadensis were observed. These findings suggest that wolves may be an important definitive host for both parasite species in western Canada. This represents the first report of wolves naturally infected with E. multilocularis in North America, and of wolves harbouring mixed infections with multiple species and genotypes of Echinococcus. These observations provide important information regarding the distribution and diversity of zoonotic species of Echinococcus in western North America, and may be of interest from public health and wildlife conservation perspectives.

  14. 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

    Quantifying spatial patterns of bird nests and nest fate provides insights into processes influencing a species’ distribution. At Cape Churchill, Manitoba, Canada, recent declines in breeding Eastern Prairie Population Canada geese (Branta canadensis interior) has coincided with increasing populations of nesting lesser snow geese (Chen caerulescens caerulescens) and Ross’s geese (Chen rossii). We conducted a spatial analysis of point patterns using Canada goose nest locations and nest fate, and lesser snow goose nest locations at two study areas in northern Manitoba with different densities and temporal durations of sympatric nesting Canada and lesser snow geese. Specifically, we assessed (1) whether Canada geese exhibited territoriality and at what scale and nest density; and (2) whether spatial patterns of Canada goose nest fate were associated with the density of nesting lesser snow geese as predicted by the protective-association hypothesis. Between 2001 and 2007, our data suggest that Canada geese were territorial at the scale of nearest neighbors, but were aggregated when considering overall density of conspecifics at slightly broader spatial scales. The spatial distribution of nest fates indicated that lesser snow goose nest proximity and density likely influence Canada goose nest fate. Our analyses of spatial point patterns suggested that continued changes in the distribution and abundance of breeding lesser snow geese on the Hudson Bay Lowlands may have impacts on the reproductive performance of Canada geese, and subsequently the spatial distribution of Canada goose nests.

    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)

    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.

    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.

    A report is presented of the year's activities of the corporation responsible for supplying electric power to Manitoba. The corporation serves all areas of the province except central Winnipeg, and its 11 generating stations have a capability of nearly 4 million kW, of which ca 3.5 millon kW is hydraulic. The various sections of the report present information on customer services; electricity generated, purchased, and exported; system development, including construction of new power plants; research and development; environmental services; personnel policies; and water management. Financial statements are also provided. Highlights of the year include: a net income of $48.6 million for the year ending 31 March 1991; the first four units of the Limestone Generating Station were placed in service ahead of schedule and under budget; the Corporation's development plans for major generation and transmission facilities received the endorsement of the Public Utilities Board; a major settlement was reached with the people of Chemawawin/Easterville and Moose Lake with respect to outstanding responsibilities related to the development of the Grand Rapids Generating Station; an agreement was reached with the Cross Lake Band of Indians to construct a weir that will create a water regime on Cross Lake that reduces or eliminates the adverse effects caused by the Lake Winnipeg Regulation Project; an export sale agreement was signed with Ontario Hydro which provides for the delivery by Manitoba Hydro of 200 megawatts of firm capacity in each year of the three-year agreement; a major commitment to energy conservation; and the employee safety record was substantially improved. 11 figs

    Full Text Available Background: First Nations people are experiencing increasing rates of obesity and type 2 diabetes but no anthropometric information exists from before the 1950s to provide context to these epidemics. Objective: To compare anthropometric indices of First Nations children and youth on first entering residential schools with historical and contemporary reference groups. Methods: This observational cross-sectional study used archival records from the Department of Indian Affairs to calculate body mass index (BMI, height for age (HA and weight for age (WA of all known children and youth undergoing physical examinations on first entering residential schools in Saskatchewan and Manitoba from 1919 to 1953. Proportions of children and youth in each BMI category were determined by age, sex, time period and residential school. Z-scores for HA and WA were determined by age group and sex. Finally, median heights and weights were compared with a non-Indigenous cohort from the 1953 Canadian survey. Results: On admission to residential schools, 1,767 First Nations children and youth (847 boys, 920 girls were more likely to have normal BMIs (79.8% than Canadian children and youth today (66.5%, but lower rates of overweight/obesity (10.9% vs. 32.0% and higher rates of underweight (9.3% vs. −2, age-specific median heights tended to be higher than Canadian children and youth in 1953. Under 3% of children and youth had WA Z-scores of >−2. Conclusions: A large majority of First Nations children and youth exhibited normal anthropometric indices on first entering residential schools in Manitoba and Saskatchewan from 1919 to 1953. These historical findings provide an important context to the current epidemics of obesity and type 2 diabetes and suggest that the nutritional conditions in these First Nations children's communities were satisfactory during the residential school era.

    Lingonberry (Vaccinium vitis-idaea L.) contains high levels of anthocyanins which are bioavailable in the kidney and may be protective against ischemia-reperfusion (IR)-induced acute kidney injury. This study investigated the effect of lingonberry juice on the IR-induced stress-activated signalling pathway and inflammatory response in the kidney. Sprague-Dawley rats subjected to kidney IR had significantly impaired kidney function, with increased activation of the JNK signalling pathway and increased inflammatory response, measured using a multiplex panel containing an extensive array of inflammatory biomarkers. In rats fed 1 mL lingonberry juice daily for 3 weeks prior to IR, kidney function was protected and attenuation of inflammatory response and JNK signalling was reflected in the reduction of the measured biomarkers. In vitro results in cultured HK-2 cells confirmed that lingonberry anthocyanins reduced JNK signalling and inflammatory gene expression after IR. This study shows, for the first time, that daily supplementation with lingonberry juice may protect against loss of kidney function induced by IR injury by modulating JNK signalling and inhibiting the subsequent inflammatory response. © 2017 Her Majesty the Queen in Right of Canada.

    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

    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

    The majority of Canadians' food acquisition occurs in retail stores. Retail science has become increasingly sophisticated in demonstrating how consumer environments influence population-level diet quality and health status. The retail food environment literature is new but growing rapidly in Canada, and there is a relative paucity of evidence from intervention research implemented in Canada. The healthy corner store model is a comprehensive complex population health intervention in small retail stores, intended to transform an existing business model to a health-promoting one through intersectoral collaboration. Healthy corner store interventions typically involve conversions of existing stores with the participation of health, community, and business sector partners, addressing business fundamentals, merchandising, and consumer demand. This article introduces pioneering experiences with the healthy corner store intervention in Canada. First, we offer a brief overview of the state of evidence within and outside Canada. Second, we discuss three urban and one rural healthy corner store initiatives, led through partnerships among community food security organizations, public health units, academics, and business partners, in Manitoba, Ontario, and Newfoundland and Labrador. Third, we synthesize the promising practices from these local examples, including aspects of both intervention science (e.g., refinements in measuring the food environment) and community-based practice (e.g., dealing with unhealthy food items and economic impact for the retailer). This article will synthesize practical experiences with healthy corner stores in Canada. It offers a baseline assessment of promising aspects of this intervention for health and health equity, and identifies opportunities to strengthen both science and practice in this area of retail food environment work.

    The heterogeneity of medical complications that lead to amputation has resulted in a diverse patient population with differing rehabilitation needs; however, the rehabilitation trends for patients with lower extremity amputations across Canada have not been studied previously. To describe trends in rehabilitation after lower extremity amputations and the factors affecting rehabilitation length of stay in Canada. Retrospective cohort analysis. Canadian inpatient rehabilitation facilities that received persons with lower extremity amputations discharged from academic or community hospitals. Patients underwent lower extremity amputations between 2006 and 2009 for nontraumatic indications and were then discharged to a rehabilitation facility. Patients were identified from the Canadian Institute for Health Information's Discharge Abstract Database that includes hospital admissions across Canada except Quebec. Inpatient rehabilitation after lower extremity amputations. Length of stay, discharge destination, and change in total and motor function scores. The analysis included 5342 persons who underwent lower extremity amputations, 1904 of whom were transferred to a rehabilitation facility (36%). Patients most commonly underwent single below-knee (74%) and above-knee (17%) amputations. The duration of rehabilitation varied by whether the amputation was performed by a vascular (median = 36 days), orthopedic (median = 38 days), or general surgeon (median = 35 days). The overall median length of stay was 36 days. Most patients (72%) subsequently were discharged home and 9% were readmitted to hospital. Predictors of longer rehabilitation included amputation by an orthopedic surgeon (beta = 5.0, P ≤ .01), older age (beta = 0.2, P ≤ .01), and a history of ischemic heart disease (beta = 3.8, P = .03) or congestive heart failure (beta = 5, P = .04). Patients who spent Canada after lower extremity amputation varies by the type of surgeon performing the amputation. Advanced age

    Aboriginals have always cared for their homeland. Hydroelectric development on the northern Manitoba rivers has resulted in a re engineering of the watersheds and has had a major impact on Aboriginal people. The hydroelectric development in the region supplies approximately 75 per cent of the electricity produced in Manitoba. Environmental and cultural disruption to the people living in the area resulted from the Churchill-Nelson Hydroelectric Project (the Project). The commissioners of the inquiry believe that solutions based on generosity and unwavering justice must be found to avoid a northern crisis. The environmental effects and social trauma caused by the Project were addressed by several presenters at the inquiry, which was held June 21-23, 2001 in Winnipeg and June 24-25, 2001 in Cross Lake, Manitoba. Part II of the report outlined the damages to the watersheds. The governments of Manitoba, Canada, as well as Manitoba Hydro are addressing adverse impacts in this document, but the authors indicated that concerted efforts are required. A list of recommendations was included in the document. The spokespersons for the governments of Manitoba, Canada and Manitoba Hydro had a different perspective concerning whether the adverse conditions were caused by the Project or whether they originated elsewhere. The Northern Flood Agreement (1977) is discussed in the next section, followed by a discussion of the South Indian and Fox Lake First Nation, two of the most affected communities. The panel recommended that rights and benefits comparable to those offered under the Northern Flood Agreement be granted to these people. The restoration of damaged ecosystems and the socio-economic recovery of the affected communities are required to extend the success of the hydroelectric project and attain self-sufficiency. 25 refs.

The commissioners of the inquiry believe that solutions based on generosity and unwavering justice must be found to avoid a northern crisis. The environmental effects and social trauma caused by the Project were addressed by several presenters at the inquiry, which was held June 21-23, 2001 in Winnipeg and June 24-25, 2001 in Cross Lake, Manitoba. Part II of the report outlined the damages to the watersheds. The governments of Manitoba, Canada, as well as Manitoba Hydro are addressing adverse impacts in this document, but the authors indicated that concerted efforts are required. A list of recommendations was included in the document. The spokespersons for the governments of Manitoba, Canada and Manitoba Hydro had a different perspective concerning whether the adverse conditions were caused by the Project or whether they originated elsewhere. The Northern Flood Agreement (1977) is discussed in the next section, followed by a discussion of the South Indian and Fox Lake First Nation, two of the most affected communities. The panel recommended that rights and benefits comparable to those offered under the Northern Flood Agreement be granted to these people. The restoration of damaged ecosystems and the socio-economic recovery of the affected communities are required to extend the success of the hydroelectric project and attain self-sufficiency. 25 refs

    The effect that land use may have on streamflow in the Carson River, and ultimately its impact on downstream users can be evaluated by simulating precipitation-runoff processes and estimating groundwater inflow in the middle Carson River in west-central Nevada. To address these concerns, the U.S. Geological Survey, in cooperation with the Bureau of Reclamation, began a study in 2008 to evaluate groundwater flow in the Carson River basin extending from Eagle Valley to Churchill Valley, called the middle Carson River basin in this report. This report documents the development and calibration of 12 watershed models and presents model results and the estimated mean annual water budgets for the modeled watersheds. This part of the larger middle Carson River study will provide estimates of runoff tributary to the Carson River and the potential for groundwater inflow (defined here as that component of recharge derived from percolation of excess water from the soil zone to the groundwater reservoir). The model used for the study was the U.S. Geological Survey's Precipitation-Runoff Modeling System, a physically based, distributed-parameter model designed to simulate precipitation and snowmelt runoff as well as snowpack accumulation and snowmelt processes. Models were developed for 2 perennial watersheds in Eagle Valley having gaged daily mean runoff, Ash Canyon Creek and Clear Creek, and for 10 ephemeral watersheds in the Dayton Valley and Churchill Valley hydrologic areas. Model calibration was constrained by daily mean runoff for the 2 perennial watersheds and for the 10 ephemeral watersheds by limited indirect runoff estimates and by mean annual runoff estimates derived from empirical methods. The models were further constrained by limited climate data adjusted for altitude differences using annual precipitation volumes estimated in a previous study. The calibration periods were water years 1980-2007 for Ash Canyon Creek, and water years 1991-2007 for Clear Creek. To

  6. Canada`s greenhouse gas emissions inventory

    Energy Technology Data Exchange (ETDEWEB)

    Jaques, A. [Environment Canada, Ottawa, ON (Canada)

    1998-09-01

    In 1994, Canada was the seventh largest global emitter of CO{sub 2}. The Kyoto Protocol has made it necessary to continue to improve methods for developing emissions inventories. An emissions inventory was defined as `a comprehensive account of air pollutant emissions and associated data from sources within the inventory area over a specified time frame that can be used to determine the effect of emissions on the environment`. The general approach is to compile large-scale emission estimates under averaged conditions for collective sources and sectors, using data that is available on a sectoral, provincial and national basis. Ideally, continuous emission monitors should be used to develop emissions inventories. Other needed improvements include additional research on emissions data, and increased support for international negotiations on reporting policies and related methodologies, verification procedures and adjustments. 1 ref., 5 figs.

  8. 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

    The high prevalence and severity of caries among Canadian First Nations children is a growing concern. Dental surgery in hospital is often necessary to treat the signs of decay but does not address the underlying factors contributing to its development. The purpose of this study was to determine the prevalence and risk factors of caregiver-reported Baby Bottle Tooth Decay (BBTD), or Severe Early Childhood Caries (S-ECC), among preschool children recruited in Phase 2 of the First Nations Regional Longitudinal Health Survey (RHS). Cross-sectional study including interviews with caregivers. This study was limited to data from Manitoba First Nations participating in the RHS Phase 2 (2008-10). Data were restricted to caregiver interviews for their child drink crystal beverages in bottles, and daily intake of soft drinks, juice, sweets and fast food were associated with increased risk. Those who reported that healthcare services were not available and were not culturally appropriate were significantly more likely to have children with S-ECC. Caregiver reports suggest that nearly 1 in every 4 children has been affected by S-ECC. Identified risk factors for Manitoba First Nations children included age, education and employment, dietary practices, access to care, and disruption to family and culture. This local evidence can be used to help inform future caries prevention activities in these Manitoba communities.

    Clarke, K.

    2009-01-01

    This report evaluated an environmental impact statement (EIS) submitted by a company proposing to develop a hydroelectric generation project in the lower Churchill River in Labrador. Construction of the facilities will alter the aquatic environment of the river as well as the receiving environment of lakes. The alterations are expected to have an impact on fish and fish habitats. The study evaluated the methods used to describe and predict impacts in the aquatic environment and examined models used for predictions in order to assess uncertainty levels. Results of the evaluation demonstrated that additional efforts are needed to document local knowledge of fish use and fish habitat, and that the magnitude of expected changes to fish habitat must be considered relative to the loss of fish habitat. The study also highlighted areas within the EIS that will require further clarification. A number of the studies used in the EIS had small sample sizes that increased the uncertainty of predictions made using the data. Uncertainties related to potential changes in flushing rates and morphological features was also needed. The impact of direct fish mortality from turbine operations was not addressed in a population context, and further information is needed to evaluate potential project-related effects on a species-by-species basis. 3 refs., 4 tabs.

  15. Methods and Data Used to Investigate Polonium-210 as a Source of Excess Gross-Alpha Radioactivity in Ground Water, Churchill County, Nevada

    Science.gov (United States)

    Seiler, Ralph L.

    2007-01-01

    Ground water is the major source of drinking water in the Carson River Basin, California and Nevada. Previous studies have shown that uranium and gross-alpha radioactivities in ground water can be greater than U.S. Environmental Protection Agency Maximum Contaminant Levels, particularly in the Carson Desert, Churchill County, Nevada. Studies also have shown that the primary source of the gross-alpha radioactivity and alpha-emitting radionuclides in ground water is the dissolution of uranium-rich granitic rocks and basin-fill sediments that have their origins in the Sierra Nevada. However, ground water sampled from some wells in the Carson Desert had gross-alpha radioactivities greater than could be accounted for by the decay of dissolved uranium. The occurrence of polonium-210 (Po-210) was hypothesized to explain the higher than expected gross-alpha radioactivities. This report documents and describes the study design, field and analytical methods, and data used to determine whether Po-210 is the source of excess gross-alpha radioactivity in ground water underlying the Carson Desert in and around Fallon, Nevada. Specifically, this report presents: 1) gross alpha and uranium radioactivities for 100 wells sampled from June to September 2001; and 2) pH, dissolved oxygen, specific conductance, and Po-210 radioactivity for 25 wells sampled in April and June 2007. Results of quality-control samples for the 2007 dataset are also presented.

    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

  1. Canada's reactor exports

    International Nuclear Information System (INIS)

    Morrison, R.W.

    1981-01-01

    A brief sketch of the development of Canada's nuclear exports is presented and some of the factors which influence the ability to export reactors have been identified. The potential market for CANDUs is small and will develop slowly. The competition will be tough. There are few good prospects for immediate export orders in the next two or three years. Nonetheless there are reasonable opportunities for CANDU exports, especially in the mid-to-late 1980s. Such sales could be of great benefit to Canada and could do much to sustain the domestic nuclear industry. Apart from its excellent economic and technical performance, the main attraction of the CANDU seems to be the autonomy it confers on purchasing countries, the effectiveness with which the associated technology can be transferred, and the diversification it offers to countries which wish to reduce their dependence on the major industrial suppliers. Each sales opportunity is unique, and marketing strategy will have to be tailored to the customer's needs. Over the next decade, the factors susceptible to Canadian government action which are most likely to influence CANDU exports will be the political commitment of the government to those reactor exports, the performance established by the four 600 MWe CANDUs now nearing completion, the continuing successful operation of the nuclear program in Ontario, and the co-ordination of the different components of Canada's nuclear program (AECL, nuclear industry, utilities, and government) in putting forth a coherent marketing effort and following through with effective project management

  2. Energy cascades in Canada

    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.

    2004-09-01

    OECD's comprehensive 2004 report on Canada's environmental policies and programmes systematically examines policy related to air, water, and nature/biodiversity as well as the interface between environmental policy and economic policy, social policy, and specific sectors. 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.

  4. Canada's Global Partnership Program

    Ellis, M.

    2007-01-01

    Curbing the proliferation of biological weapons (BW) is an essential element of the Global Partnership Against the Spread of Weapons and Materials of Mass Destruction. At the Kananaskis Summit in June 2002, G8 Leaders committed to prevent terrorists, or those that harbour them, from acquiring or developing biological weapons and related materials, equipment and technology. To this end, Canada's Global Partnership Program is investing heavily in biological non-proliferation activities in countries of the former Soviet Union. A comprehensive strategy has been developed to help improve biological safety (biosafety) and biological security (biosecurity) with provision for addressing dual-use concerns. Raising awareness and creating a self-sustaining culture of biosecurity is a key driver of the program. Through this strategy, Canada is assisting various FSU countries to: develop and implement effective and practical biosafety/biosecurity standards and guidelines; establish national and/or regional biosafety associations; develop and deliver effective biosafety and biosecurity training; put in place enhanced physical security measures and equipment. In addition to biosafety and biosecurity, the GPP supports a broad range of Biological Non-Proliferation projects and initiatives, including dozens of projects aimed at redirecting former biological weapons scientists. To date, most of these activities have been supported through Canada's contribution to the International Science and Technology Center (ISTC) and the Science and Technology Centre Ukraine (STCU).(author)

    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

  6. TOXICanada: 13 good reasons to establish a Clean Canada Fund

    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

    Lyme disease is emerging in eastern and central Canada, and most cases are diagnosed using the two-tier serological test (Enzyme Immuno Assay [EIA] followed by Western blot [WB]). Simplification of this algorithm would be advantageous unless it impacts test performance. In this study, accuracy of individual proteins of the IgG WB algorithm in predicting the overall test result in samples from Canadians was assessed. Because Borrelia burgdorferi strains vary geographically in Canada, geographic variations in serological responses were also explored. Metrics of relative sensitivity, specificity and the kappa statistic measure of concordance were used to assess the capacity of responses to individual proteins to predict the overall IgG WB result of 2524 EIA (C6)-positive samples from across Canada. Geographic and interannual variations in proportions of samples testing positive were explored by logistic regression. No one protein was highly concordant with the IgG WB result. Significant variations were found amongst years and geographic regions in the prevalence of samples testing positive using the overall IgG WB algorithm, and for individual proteins of the algorithm. In most cases the prevalence of samples testing positive were highest in Nova Scotia, and lower in samples from Manitoba westwards. These findings suggest that the current two tier test may not be simplified and continued use of the current two-tier test method and interpretation is recommended. Geographic and interannual variations in the prevalence of samples testing positive may be consistent with B. burgdorferi strain variation in Canada, and further studies are needed to explore this.

  9. Site-specific estimates of water yield applied in regional acid sensitivity surveys across western Canada

    2010-08-01

    Full Text Available Runoff or water yield is an important input to the Steady-State Water Chemistry (SSWC model for estimating critical loads of acidity. Herein, we present site-specific water yield estimates for a large number of lakes (779 across three provinces of western Canada (Manitoba, Saskatchewan, and British Columbia using an isotope mass balance (IMB approach. We explore the impact of applying site-specific hydrology as compared to use of regional runoff estimates derived from gridded datasets in assessing critical loads of acidity to these lakes. In general, the average water yield derived from IMB is similar to the long-term average runoff; however, IMB results suggest a much larger range in hydrological settings of the lakes, attributed to spatial heterogeneity in watershed characteristics and landcover. The comparison of critical loads estimates from the two methods suggests that use of average regional runoff data in the SSWC model may overestimate critical loads for the majority of lakes due to systematic skewness in the actual runoff distributions. Implications for use of site-specific hydrology in regional critical loads assessments across western Canada are discussed.

    The amount of standing dead and downed woody debris along an upland chromosequence was measured in an effort to investigate the role of fire-killed woody debris as a source of soil carbon in black spruce stands in Manitoba. Based on the measurement data and existing primary production values, a mass balance model was used to assess the potential impact of fire-killed wood on long-term carbon storage at this site. Long-term carbon was represented by the amount of carbon stored in deeper soil organic layers, persisting over millenia. Between 10 and 60 per cent of the deep-soil carbon was estimated to have been derived from wood biomass. The actual amount appears to be most affected by fire return interval, decay rate of wood, the amount of net primary production, and the decay rate of the post-fire carbon pool. Although the model was less sensitive to fire consumption rates and to rates at which standing dead wood becomes woody debris, all model runs clearly established that woody debris plays an important role in long-term carbon storage in this area. 53 refs., 4 tabs., 4 figs.

  11. Determining effects of an all weather logging road on winter woodland caribou habitat use in south-eastern Manitoba

    2007-04-01

    Full Text Available The Owl Lake boreal woodland caribou population is the most southerly population in Manitoba. It is provincially ranked as a High Conservation Concern Population. Forestry operations exist in the area and there are plans for further forest harvest and renewal. The Happy Lake logging road is the only main access through the Owl Lake winter range. This logging road is currently closed to the public and access is limited to forestry operations during specific times of the year. An integrated forestry/caribou management strategy for the area provides for the maintenance of minimum areas of functional habitat. Habitat quality along the road was compared to habitat quality in the winter core use areas, within the winter range and outside the winter range. To evaluate the extent of functional habitat near the road, we conducted animal location and movement analysis using GPS data collected from January 2002 to March 2006. Habitat quality in the winter range, core use areas and along the road were assessed and found to be similar. Analysis of caribou locations and movement illustrate less use of high quality habitat adjacent to the Happy Lake Road. Loss of functional habitat is suggested to occur within 1 kilometre of the road. This potential loss of functional habitat should be incorporated into integrated forestry and caribou conservation strategies. Road management is recommended to minimize the potential sensory disturbance and associated impacts of all weather access on boreal woodland caribou.

  12. Vegetation characteristics of forest stands used by woodland caribou and those disturbed by fire or logging in Manitoba

    Full Text Available This study examined woodland caribou (Rangifer tarandus caribou in an area known as the Kississing-Naosap caribou range in west central Manitoba. The vegetation characteristics of areas used by caribou and areas disturbed by fire or logging were measured in order to develop a model to estimate habitat quality from parameters collected during stan¬dard resource inventories. There was evidence that habitat index values calculated using a visual score-sheet index could be used as the basis to relate parameters commonly collected during resource inventories to habitat suitability. Use of this model to select long and short-term leave areas during forest management planning could potentially mitigate some of the negative impacts of forest harvesting. Abundance of arboreal lichen and wind-fallen trees were important predictor variables in the suitability model, but their inclusion did not explain more variance in habitat suitability than models that did not include them. Extreme post-fire deadfall abundance may play a role in predator-prey dynamics by creating habitat that is equally unsuitable for all ungulates, and thus keeping both moose and caribou densities low.

  14. Transnational surrogacy: Canada's contradictions.

    Science.gov (United States)

    Lozanski, Kristin

    2015-01-01

    Transnational commercial surrogacy represents a form of medical tourism undertaken by intended parents who seek to hire women in other countries, increasingly often in the global South, as surrogates. While much of the scholarly literature focuses on the conditions of surrogacy within host countries, such as India, there has been limited analysis of transnational surrogacy focused upon origin countries. In this article, I build upon the scholarship that explores the impact of host country structures on transnational surrogacy, with special attention to the significance of Canadian citizenship policy through analysis of legislation and policy vis-à-vis transnational commercial surrogacy. The Canadian case demonstrates clear contradictions between the legislation and policy that is enacted domestically to prohibit commercial surrogacy within Canada and legislation and policy that implicitly sanctions commercial surrogacy through the straightforward provision of citizenship for children born of such arrangements abroad. The ethical underpinnings of Canada's domestic prohibition of commercial surrogacy, which is presumed to exploit women and children and to impede gender equality, are violated in Canada's bureaucratic willingness to accept children born of transnational commercial surrogacy as citizens. Thus, the ethical discourses apply only to Canadian citizens within Canadian geography. The failure of the Canadian government to hold Canadian citizens who participate in transnational commercial surrogacy to the normative imperatives that prohibit the practice within the country, or to undertake a more nuanced, and necessarily controversial, discussion of commercial surrogacy reinforces transnational disparities in terms of whose bodies may be commodified as a measure of gendered inequality.

    The situation of the energy supply of Canada is characterized by its geographic location and by the dispersal of the energy consumers over a wide area. At present, the energy supply leaving the successful CANDU nuclear energy programme out of account, is based mainly on crude oil, natural gas, and electricity as well as on coal imported from the USA. The targets of Canadian enery policies and energy research are stated as follows: a) Reducing and optimizing energy consumption, b) introducing district heating, and c) utilizing the extensive local coal deposits.

    2010-04-01

    In Canada, increased morbidity and shorter life expectancy have been found among those with lower incomes and lower levels of education, but there has been little examination of socioeconomic variation in food and nutrient intake. Using data from the 2004 Canadian Community Health Survey, we examined the relationship between household income and education level and adults' and children's intakes of energy, fibre, micronutrients, and number of servings consumed of food groups from Canada's Food Guide. To explore the public health significance of observed associations, we estimated the prevalence of inadequacy for selected nutrients for adults, stratifying by household income, education level, and sex. We found that a higher household income adequacy and (or) higher levels of education were associated with increased consumption of milk and alternatives, and vegetables and fruit, and significantly higher vitamin, mineral, and fibre intakes among both adults and children. The prevalence of inadequate nutrient intakes among adults was higher among adults with the lowest level of income adequacy or educational attainment, compared with others. Our results suggest that the nutritional quality of Canadians' food intakes is, in part, a function of their social position. The impact of policy and program interventions needs to be examined across socioeconomic strata to ensure that actions reduce rather than exacerbate nutrition inequities.

  19. Energy in Canada

    Dixon, R.S.

    1980-12-01

    Canada's historical energy consumption, its current consumption and its likely requirements by the turn of the century are reviewed. It is estimated that at least 50% more energy will be required in the year 2000 than is consumed now, assuming a minimum 2% growth rate in primary energy consumption. Both non-renewable and renewable energy resources are examined in the light of these future energy requirements and the need to substitute alternative energy sources for conventional oil in various end uses. The comparative risks involved in energy production are also reviewed. Most of the increase in energy consumption and the substitution of oil over the next 20 years is likely to be met by conventional energy sources, since indigenous reserves are extensive and the relevant technologies well-established. Coal, nuclear and hydro reserves could cover the increase in energy demand until well into the next century, and natural gas reserves are sufficient to bridge the gap during conversion from oil to other energy sources. Nuclear power using advanced fuel cycles and oil from tar sands offer Canada long-term security. The penetration of unconventional energy sources is likely to be relatively small during the next 20 years. However, the most promising may become significant in the next century. (author)

    2006-01-01

    This paper provided an outline of Canada's Clean Air Act and examined some of the regulatory changes that will occur as a result of its implementation. The Act is being introduced to strengthen the legislative basis for taking action on reducing air pollution and GHGs, and will allow the government to regulate both indoor and outdoor air pollutants and GHGs. The Act will require the Ministers of the Environment and Health to establish national air quality objectives, as well as to monitor and report on their attainment. The Canadian Environmental Protection Act will be amended to enable the government to regulate the blending of fuels and their components. The Motor Vehicle Fuel Consumption Standards Act will also be amended to enhance the government's authority to regulate vehicle fuel efficiency. The Energy Efficiency Act will also be expanded to allow the government to set energy efficiency standards and labelling requirements for a wider range of consumer and commercial products. The Act will commit to short, medium and long-term industrial air pollution targets. Regulations will be proposed for emissions from industry; on-road and off-road vehicles and engines; and consumer and commercial products. It was concluded that the Government of Canada will continue to consult with provinces, territories, industries and Canadians to set and reach targets for the reduction of both indoor and outdoor air pollutants and GHG emissions. 6 figs

    2014-04-01

    The western Churchill Province of the Canadian Shield experienced a prolonged and complex formation history (ca. 4.04 to 1.70 Ga), with evidence for multiple episodes of orogenesis and regional magmatic activity. Here we report on the oxygen isotopic compositions of garnet and zircon recovered from lower crustal xenoliths, which have U-Pb ages between ca. 3.5 and 1.7 Ga. Overall, zircon from four metabasite xenoliths from the Rankin Inlet sample suite have δ18O values ranging from + 5.5 to + 8.6‰. Zircon from three metatonalite/anorthosite xenoliths and five metabasite xenoliths from the Repulse Bay sample suite have δ18O values of + 5.6 to + 8.3‰. High δ18O values (> + 6.0‰) for the oldest igneous zircon cores (ca. 3.5 Ga and 3.0-2.6 Ga) indicate that their metatonalite/anorthosite protolith magmas were generated from, or had assimilated, supracrustal rocks that interacted previously with surface-derived fluids. Igneous zircon cores (ca. 2.9-2.6 Ga) from one metabasite xenolith have δ18O values of + 5.6 to + 6.4‰, which suggests a formation from a mantle-derived basaltic/gabbroic magma. Metamorphic zircon cores (ca. 2.0-1.9 Ga) from one metabasite xenolith commonly have δ18O values between + 6.0 and + 6.3‰, which is indicative of a basalt/gabbro protolith and localized reworking of the lower crust caused by regional-scale plate convergence. The wide range of δ18O values (+ 5.5 to + 8.3‰) for ca. 1.75-1.70 Ga metamorphic zircon rims (identified in all xenoliths) indicates regional transient heating and reworking of mantle- and supracrustal-derived crust, induced by magmatic underplating along the crust-mantle boundary.

    Equine granulocytic anaplasmosis (EGA) and Lyme borreliosis (LB) are an emerging concern in Canada. We estimated the seroprevalence of EGA and equine LB by testing 376 convenience serum samples from 3 provinces using a point-of-care SNAP(®) 4Dx(®) ELISA (IDEXX Laboratories, Westbrook, Maine, USA), and investigated the agreement between the point-of-care ELISA and laboratory-based serologic tests. The estimated seroprevalence for EGA was 0.53% overall (0.49% in Saskatchewan, 0.71% in Manitoba), while the estimated seroprevalence for LB was 1.6% overall (0.49% in Saskatchewan, 2.86% in Manitoba). There was limited agreement between the point-of-care ELISA and an indirect fluorescent antibody test for EGA (kappa 0.1, PABAK 0.47) and an ELISA/Western blot combination for LB (kappa 0.23, PABAK 0.71). While the SNAP(®) 4Dx(®) ELISA yielded expected seroprevalence estimates, further evaluation of serologic tests for the purposes of disease exposure recognition may be needed.

    Full Text Available Traditional financial planning is based on a fundamental rule of thumb: Aim to save enough for retirement to replace 80 per cent of your pre-retirement income with income from pensions and assets. Millions of Canadians follow this formula. Yet, there is no guarantee this approach is consistent with a savings plan that will allow them to experience their optimal standard of living — given their income — throughout their working lives. Consumption smoothing happens when a consumer projects her income and her non-discretionary expenses (such as mortgage payments all the way up until the end of her life, and is able to determine her household discretionary spending power over time, to achieve the smoothest living standard path possible without going into debt. When consumption smoothing is calculated accurately, a person’s lifestyle should be roughly the same whether she is in her 30s with small children, in her 50s with kids in college, or in retirement, with adult children. Consumption smoothing allows that to happen. But while it is conceptually straightforward, consumption smoothing requires the use of advanced numerical techniques. Now, Canadian families have access to a powerful consumption-smoothing tool: ESPlannerBASIC Canada. This free, secure and confidential online tool will allow Canadian families to safely and securely enter their earnings and other financial resources and will calculate for them how much they can spend and how much they should save in order to maintain their lifestyle from now until they die, without going into debt. It will also calculate how much life insurance they should buy, to ensure that household living standards are not affected after a family member dies. Users can easily and instantly run “what-if” scenarios to see how retiring early (or later, changing jobs, adjusting retirement contributions, having children, moving homes, timing RRSP withdrawals, and other financial and lifestyle decisions would

    Canadian tritium activites comprise three major interests: utilites, light manufacturers, and fusion. There are 21 operating CANDU reactors in Canada; 19 with Ontario Hydro and one each with Hydro Quebec and New Brunswick Power. There are two light manufacturers, two primary tritium research facilities (at AECL Chalk River and Ontario Hydro Technologies), and a number of industry and universities involved in design, construction, and general support of the other tritium activities. The largest tritum program is in support of the CANDU reactors, which generate tritium in the heavy water as a by-product of normal operation. Currently, there are about 12 kg of tritium locked up in the heavy water coolant and moderator of these reactors. The fusion work is complementary to the light manufacturing, and is concerned with tritium handling for the ITER program. This included design, development and application of technologies related to Isotope Separation, tritium handling, (tritiated) gas separation, tritium-materials interaction, and plasma fueling

    The current situation in the exploration for uranium in British Columbia, the Yukon, the Northwest Territories, and Saskatchewan is reviewed. A moratorium on exploration has been in effect in British Columbia since 1980; it is due to expire in 1987. Only the Blizzard deposit appears to have any economic potential. The Lone Gull discovery in the Thelon Basin of the Northwest Territories has proven reserves of more than 35 million pounds U 3 O 8 grading 0.4%. Potentially prospective areas of the northern Thelon Basin lie within a game sanctuary and cannot be explored. Exploration activity in Saskatchewan continues to decline from the peak in 1980. Three major deposits - Cluff Lake, Rabbit Lake and Key Lake - are in production. By 1985 Saskatchewan will produce 58% of Canada's uranium, and over 13% of the western world's output. (L.L.)

    Canada is a high-income country with a population of 33 million people. Its economic performance has been solid despite the recession that began in 2008. Life expectancy in Canada continues to rise and is high compared with most OECD countries; however, infant and maternal mortality rates tend to be worse than in countries such as Australia, France and Sweden. About 70% of total health expenditure comes from the general tax revenues of the federal, provincial and territorial governments. Most public revenues for health are used to provide universal medicare (medically necessary hospital and physician services that are free at the point of service for residents) and to subsidise the costs of outpatient prescription drugs and long-term care. Health care costs continue to grow at a faster rate than the economy and government revenue, largely driven by spending on prescription drugs. In the last five years, however, growth rates in pharmaceutical spending have been matched by hospital spending and overtaken by physician spending, mainly due to increased provider remuneration. The governance, organization and delivery of health services is highly decentralized, with the provinces and territories responsible for administering medicare and planning health services. In the last ten years there have been no major pan-Canadian health reform initiatives but individual provinces and territories have focused on reorganizing or fine tuning their regional health systems and improving the quality, timeliness and patient experience of primary, acute and chronic care. The medicare system has been effective in providing Canadians with financial protection against hospital and physician costs. However, the narrow scope of services covered under medicare has produced important gaps in coverage and equitable access may be a challenge in these areas.

    compilation of 92 countries, Canada finds itself in the middle of the pack with the 35th highest tax burden on capital. The blame for this is shared by provincial and federal governments. In recent years, governments in Newfoundland and Labrador, New Brunswick, Alberta and B.C. have all raised business taxes (Alberta now has a higher corporate income tax than B.C. Ontario or Quebec. Quebec has scaled back incentives for investors, Manitoba increased its sales tax, and B.C. eliminated the harmonized sales tax, reintroducing the burden on business inputs implicit in the provincial retail sales tax. With the U.S. election of Donald Trump and a Republican Congress promising to reduce corporate income tax rates, as well as the recent affirmation by British Prime Minister Theresa May to lower the U.K. corporate income tax rate to 17 per cent, the pressure will be to reduce, not increase corporate income taxes in the next several years. Should the U.S. dramatically reduce its corporate tax rate, Canada will lose its business tax advantage altogether. Just as concerning, Canada has created a tax system that discriminates against the service sector, including transportation, communications, construction, trade, and business and financial services, all of which are among the fastest-growing sectors, and play a key role in facilitating innovation, infrastructure and trade. Canada’s tax policies continue to favour slower-growing sectors, namely manufacturing and resources. The good news is that Canada can regain competitiveness without drastic tax reform. It is clear that there needs to be greater neutrality among sectors so that service industries are not discriminated against (the same is true for large businesses versus small businesses. Meanwhile, those provinces that still have a retail sales tax can improve their attractiveness by moving to the HST, as other provinces have. The federal government is also in the midst of reviewing subsidies and other tax expenditures that create

    Full Text Available This article explores food-related activities and their impacts on sustainable livelihood assets, food sovereignty, and food security, and provides insight for future food-related community development. Analysis is based on community food assessments conducted in 14 Northern Manitoba communities and included a food security survey, price survey, and interviews. The lack of community control over development in First Nation and other Northern remote and rural communities in Northern Manitoba is found to undermine both food sovereignty and sustainable livelihoods, while creating high levels of food insecurity. According to logit models, sharing country foods increases food sovereignty and sustainable livelihoods, and has a stronger relationship to food security than either road access to retail stores in urban centres or increased competition between stores. The model predicts that rates of food insecurity for a community with a country foods program and with access to public transit and roads at 95% would be lower than the Canadian average of 92%.RÉSUMÉCet article explore les activités relatives à l’alimentation et leur impact sur les biens durables ainsi que sur la souveraineté et la sécurité alimentaires tout en ouvrant des perspectives sur le développement communautaire futur relatif à l’alimentation.

    Canada has for the fifth time in a row been chosen the best industrialized country in the world in which to initiate and run a business. The Norwegian interest in Canada has grown strongly the last years and Norwegian companies have invested over 20 billion NOK there. Canada is the perfect gateway to the large markets in the USA. Norway is currently Canada's 15th largest trading partner. In addition to low costs and strategic location, Canada has the most highly educated workforce in the world. A company on the Canadian side of the US border has the same access to the American market as a US-based company. There is even a Norwegian company in Canada that exports 100 per cent of its products across the border to the USA. The trade between the USA and Canada is more extensive than between the USA and all the EU countries together. Furthermore, Canadian companies concentrating on research and education are given a generous tax credit

    Wellons Canada is a British Columbia-based company that specializes in the manufacture and installation of lumber drying and energy conversion equipment. This brochure provided details of the Wellons energy system designed for oriented strand board (OSB) plants. The brochure outlined the system's scope of supply, and provided illustrations of system procedures from the initial wet fuel bin through to the electric precipitator used for air clean-up. During the process, fuel was conveyed from the bin to metering bins into combustors and through a cyclo-blast cell. Forced draft fan systems were then used to provide primary and secondary combustion air. Radiant heaters were then used. A drop-out chamber was supplied to allow for complete combustion of fuel particles and to provide a drop-out of ash. A fan was then used to deliver diluent air to maintain the set point temperature in the hot gas stream. Refractory lined hot gas ducts were used to deliver heat to the dryers. Hot gas was then drawn through a multi-cyclone collector for ash removal. Electrostatic precipitators were used to clean up emissions on a continuous operating basis. An automatic system was used to collect ash from the combustion system grates and other areas. Details of installation services provided by the company were also included. 42 figs.

    To assess whether provinces with Routine Notification and Request (RNR) legislation have sustained increases in corneal tissue supply and decreases in wait times for corneal transplantation surgery. Cross-sectional survey of Canadian corneal transplant (CT) surgeons and eye banks. Canadian CT surgeons and representatives from the 10 Canadian eye banks. Voluntary and anonymous surveys were distributed between July and October 2009. Eligible CT surgeons were defined as ophthalmologists who practice in Canada; currently perform Penetrating keratoplasty (PKP), Deep anterior lamellar keratoplasty (DALK), Deep lamellar endothelial keratoplasty (DLEK), Descemet stripping endothelial keratoplasty (DSEK), or Descemet membrane endothelial keratoplasty (DMEK); and have obtained tissues from a Canadian eye bank. From 2006 to 2009, for provinces with RNR legislation and where data are available, mean wait times from date of diagnosis to date of CT surgery have increased: in Ontario, from 31 ± 34 weeks to 36 ± 27 weeks; in British Columbia, from 39 ± 20 weeks to 42 ± 35 weeks; in Manitoba, from 32 ± 23 weeks to 49 ± 36 weeks. In addition, the amount of corneal tissue in RNR provinces suitable for transplant, with the exception of British Columbia, has declined between 2006 and 2008: in Ontario, 1186 tissues to 999 tissues (16% decline); in Manitoba, 92 tissues to 83 tissues (10% decline); in New Brunswick, 129 tissues to 98 tissues (24% decline). Although initially effective, RNR legislation has not sustained an increase in corneal tissue availability nor has it shortened wait times in most provinces. Incorporation of community hospitals into the RNR catchment, improved enforcement, and continued education of hospital staff regarding the RNR process may be effective in making this legislation more sustainable in the long term.

    Full Text Available Wildland fires are the main natural disturbance shaping forest structure and composition in eastern boreal Canada. On average, more than 700 000 ha of forest burns annually and causes as much as CAD 2.9 million worth of damage. Although we know that occurrence of fires depends upon the coincidence of favourable conditions for fire ignition, propagation, and fuel availability, the interplay between these three drivers in shaping spatiotemporal patterns of fires in eastern Canada remains to be evaluated. The goal of this study was to reconstruct the spatiotemporal patterns of fire activity during the last century in eastern Canada's boreal forest as a function of changes in lightning ignition, climate, and vegetation. We addressed this objective using the dynamic global vegetation model LPJ-LMfire, which we parametrized for four plant functional types (PFTs that correspond to the prevalent tree genera in eastern boreal Canada (Picea, Abies, Pinus, Populus. LPJ-LMfire was run with a monthly time step from 1901 to 2012 on a 10 km2 resolution grid covering the boreal forest from Manitoba to Newfoundland. Outputs of LPJ-LMfire were analyzed in terms of fire frequency, net primary productivity (NPP, and aboveground biomass. The predictive skills of LPJ-LMfire were examined by comparing our simulations of annual burn rates and biomass with independent data sets. The simulation adequately reproduced the latitudinal gradient in fire frequency in Manitoba and the longitudinal gradient from Manitoba towards southern Ontario, as well as the temporal patterns present in independent fire histories. However, the simulation led to the underestimation and overestimation of fire frequency at both the northern and southern limits of the boreal forest in Québec. The general pattern of simulated total tree biomass also agreed well with observations, with the notable exception of overestimated biomass at the northern treeline, mainly for PFT Picea. In these

    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

The MOU includes tokamaks, plasma physics, fusion technology, fusion fuels and other approaches to fusion energy (as alternatives to tokamaks). STOR-M Tokamak was restarted at the University of Saskatchewan following upgrades to the plasma chamber to accommodate the Compact Toroid (CT) injector. The CT injector has a flexible attachment thus allowing for injection angle adjustments. Real-time video images of a single plasma discharge on TdeV showing that as the plasma density increases, in a linear ramp divertor, the plasma contact with the horizontal plate decreases while contact increases with the oblique plate. Damage-resistant diffractive optical elements (DOE) have been developed for Inertial Confinement Fusion (ICF) research by Gentac Inc. and the National Optics Institute, laser beam homogeniser and laser harmonic separator DOE can also be made using the same technology. Studies using TdeV indicate that a divertor will be able to pump helium from the tokamak with a detached-plasma divertor but helium extraction performance must first be improved, presently the deuterium:helium retention radio-indicates that in order to pump enough helium through a fusion reactor, too much deuterium-tritium fuel would be pumped out. 2 fig

  2. SCWR Concept in Canada

    2014-08-15

    AECL is designing the Canadian SCWR concept, which has evolved from the well-established pressuretube type CANDU® reactor. The Canadian SCWR is designed to produce electrical energy as the main product, plus process heat, hydrogen, industrial isotopes, and drinking water (through the desalination process) as supplementary products, all within a more compact reactor building. Another potential application of the available co-generated process heat is the extraction and refining of oil sands, which is presently achieved using co-generation with natural gas turbines and process heat. The extraction and upgrading process requires: thermal power to lower the viscosity and extract the oil; electric power for separation and refining equipment; and hydrogen gas for upgrading the oil product prior to transport. A National Program has been established in Canada to support R&D studies for the Canadian SCWR design. It covers key areas of interest (such as thermal hydraulics, safety, materials, and chemistry) to participants in the Generation-IV International Forum (GIF) SCWR designs. Results generated from the program are contributed to the GIF SCWR project management boards (PMBs). For example, heat transfer correlations have been derived using experimental data primarily obtained from fossil-plant related studies (which were started as early as 1930s. Materials and chemistry studies have evolved from operating experience of fossil-fired power plants to a) develop, and perform targeted testing of, materials for key components, in particular in-core reactor components that will be exposed to conditions not encountered in a fossil-fired boiler (such as irradiation and water radiolysis), and b) develop a suitable water chemistry to minimize corrosion and corrosion product transport.

    Accurate crop growth stage estimation is important in precision agriculture as it facilitates improved crop management, pest and disease mitigation and resource planning. Earth observation imagery, specifically Synthetic Aperture Radar (SAR) data, can provide field level growth estimates while covering regional scales. In this paper, RADARSAT-2 quad polarization and TerraSAR-X dual polarization SAR data and ground truth growth stage data are used to model the influence of canola growth stages on SAR imagery extracted parameters. The details of the growth stage modeling work are provided, including a) the development of a new crop growth stage indicator that is continuous and suitable as the state variable in the dynamic estimation procedure; b) a selection procedure for SAR polarimetric parameters that is sensitive to both linear and nonlinear dependency between variables; and c) procedures for compensation of SAR polarimetric parameters for different beam modes. The data was collected over three crop growth seasons in Manitoba, Canada, and the growth model provides the foundation of a novel dynamic filtering framework for real-time estimation of canola growth stages using the multi-sensor and multi-mode SAR data. A description of the dynamic filtering framework that uses particle filter as the estimator is also provided in this paper.

    Alberta, Saskatchewan, and Manitoba, the three Prairie provinces of Canada, and their economies strongly depend on the petroleum industry. However, climate change may have potential impacts on the sector that could reverberate onto the socio-economic fabric of the provinces. The petroleum industry in the Prairies is faced with a big challenge: how to adapt to the changing climatic conditions so that they maintain or improve their economic and environmental efficiencies. The attitudes of the different stakeholders concerning climate change and the appropriate measures to be implemented by the petroleum industry were obtained through a questionnaire-based survey conducted between February and June 2001. Based on the responses received, a Chi-square statistical test was applied to look at the complex interactions in the results. An analysis of a number of petroleum-related processes and activities vulnerable to climate change was performed. A sound foundation was obtained for the decision-making process on the climate change measures required in the petroleum industry in the Prairies. 14 refs., 7 tabs

    Full Text Available The major objective of this paper is to show that migrants are positively selected whether they are driven by economic factors or by non-economic factors, and whether they are motivated by pull factors or push factors. Using “five-year migration data” from the 1981 to 2001 censuses of Canada, we find that the education gradient of out-migration is apparent in every region, with the highly educated being more mobile than the less educated. However, the pattern is most pronounced in the Atlantic region, Quebec, and Manitoba/Saskatchewan, the regions experiencing poorer economic conditions and persistent net losses through migration. The three high-income provinces, Ontario, Alberta, and British Columbia not only experience lower overall net losses, but are also less likely to lose their better educated persons—even during bad economic times. Quebec emerges as a special case where economic as well as linguistic-political factors play an important role in governing the out-migration patterns of the better educated, particularly those belonging to the non-Francophone group.

    The latitudinal distribution of fallout sup(137)Cs in Canada has been determined along a transect extending from 50 degrees to 82 degrees N in 1980. The sup(137)Cs content of lichens, bryophytes, and cushionlike vascular species was measured at 16 sites between Brandon, Manitoba, and Alert, Ellesmere Island. Lichen species were shown to be the most effecive biological monitors of sup(137)Cs deposition because of their specific morphology, longevity, and slow growth rates. Dry, exposed ridges were the sites of the highest sup(137)Cs retention by plants. sup(137)Cs levels in vegetation followed a bell-shaped distribution along the transect and the maximum accumulation was measured in samples collected between 60 degrees and 70 degrees N ((10 nCi msup(-2) at 63 degrees N) (1 Ci = 37 GBq). This distribution is the combined results of the original latitudinal deposition of sup(137)Cs, the expired portion of its physical half-life, and the efficiency of biotic and abiotic removal processes along the studied corridor. It is suggested that the long-term implications of sup(137)Cs in the northern food chain ought to be followed and studied more closely in the light of the data presented

    A network of 54 ring-width chronologies is used to estimate changes in summer climate within the Winnipeg River basin, Canada, since AD 1783. The basin drains parts of northwestern Ontario, northern Minnesota and southeastern Manitoba, and is a key area for hydroelectric power production. Most chronologies were developed from Pinus resinosa and P. strobus, with a limited number of Thuja occidentalis, Picea glauca and Pinus banksiana. The dominant pattern of regional tree growth can be recovered using only the nine longest chronologies, and is not affected by the method used to remove variability related to age or stand dynamics from individual trees. Tree growth is significantly, but weakly, correlated with both temperature (negatively) and precipitation (positively) during summer. Simulated ring-width chronologies produced by a process model of tree-ring growth exhibit similar relationships with summer climate. High and low growth across the region is associated with cool/wet and warm/dry summers, respectively; this relationship is supported by comparisons with archival records from early 19th century fur-trading posts. The tree-ring record indicates that summer droughts were more persistent in the 19th and late 18th century, but there is no evidence that drought was more extreme prior to the onset of direct monitoring.

    Lyme disease caused by the spirochete Borrelia burgdorferi is a multisystem disorder characterized by three clinical stages: dermatologic, neurologic, and rheumatologic. The number of known Lyme disease-endemic areas in Canada is increasing as the range of the vector Ixodes scapularis expands into the eastern and central provinces. Southern Ontario, Nova Scotia, southern Manitoba, New Brunswick, and southern Quebec are now considered Lyme disease-endemic regions in Canada. The use of field surveillance to map risk and endemic regions suggests that these geographic areas are growing, in part due to the effects of climate warming. Peripheral facial nerve palsy is the most common neurologic abnormality in the second stage of Lyme borreliosis, with up to 25% of Bell palsy (idiopathic peripheral facial nerve palsy) occurring due to Lyme disease. Here we present a case of occult bilateral facial nerve palsy due to Lyme disease initially diagnosed as Bell palsy. In Lyme disease-endemic regions of Canada, patients presenting with unilateral or bilateral peripheral facial nerve palsy should be evaluated for Lyme disease with serologic testing to avoid misdiagnosis. Serologic testing should not delay initiation of appropriate treatment for presumed Bell palsy.

    Full Text Available Objectives. The high prevalence and severity of caries among Canadian First Nations children is a growing concern. Dental surgery in hospital is often necessary to treat the signs of decay but does not address the underlying factors contributing to its development. The purpose of this study was to determine the prevalence and risk factors of caregiver-reported Baby Bottle Tooth Decay (BBTD, or Severe Early Childhood Caries (S-ECC, among preschool children recruited in Phase 2 of the First Nations Regional Longitudinal Health Survey (RHS. Study Design. Cross-sectional study including interviews with caregivers. Methods. This study was limited to data from Manitoba First Nations participating in the RHS Phase 2 (2008–10. Data were restricted to caregiver interviews for their child <72 months of age. The main variable of interest was caregiver-reported BBTD, an antecedent term for S-ECC. Data analysis included descriptive statistics and bivariate analyses; p≤0.05 was significant. Results. Overall, caregivers of 431 preschool children responded. According to caregiver reports, 102/410 (24.9% children had S-ECC. Further, 65.0% responded that their child had already undergone treatment for caries. Children with S-ECC were significantly older than those without. S-ECC was also associated with paternal education levels and employment status, and maternal smoking during pregnancy. Breastfed children were less likely to have S-ECC, while consuming drink crystal beverages in bottles, and daily intake of soft drinks, juice, sweets and fast food were associated with increased risk. Those who reported that healthcare services were not available and were not culturally appropriate were significantly more likely to have children with S-ECC. Conclusions. Caregiver reports suggest that nearly 1 in every 4 children has been affected by S-ECC. Identified risk factors for Manitoba First Nations children included age, education and employment, dietary practices

    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.

    2013-06-01

    The Hudson Bay Lowland (HBL) of northern Ontario, Manitoba and Quebec, Canada is the second largest contiguous peatland complex in the world, currently containing more than half of Canada's soil carbon. Recent concerns about the ecohydrological impacts to these large northern peatlands resulting from climate change and resource extraction have catalyzed a resurgence in scientific research into this ecologically important region. However, the sheer size, heterogeneity and elaborate landscape arrangements of this ecosystem raise important questions concerning representative sampling of environmental media for chemical or physical characterization. To begin to quantify such variability, this study assessed the small-scale spatial (1m) and short temporal (21 day) variability of surface pore-water biogeochemistry (pH, dissolved organic carbon, and major ions) in a Sphagnum spp.-dominated, ombrotrophic raised bog, and a Carex spp.-dominated intermediate fen in the HBL. In general, pore-water pH and concentrations of dissolved solutes were similar to previously reported literature values from this region. However, systematic sampling revealed consistent statistically significant differences in pore-water chemistries between the bog and fen peatland types, and large within-site spatiotemporal variability. We found that microtopography in the bog was associated with consistent differences in most biogeochemical variables. Temporal changes in dissolved solute chemistry, particularly base cations (Na(+), Ca(2+) and Mg(2+)), were statistically significant in the intermediate fen, likely a result of a dynamic connection between surficial waters and mineral-rich deep groundwater. In both the bog and fen, concentrations of SO4(2-) showed considerable spatial variability, and a significant decrease in concentrations over the study period. The observed variability in peatland pore-water biogeochemistry over such small spatial and temporal scales suggests that under-sampling in

    1992-01-01

    A summary is presented of discussions and conclusions at a workshop held to examine the potential effects of hydroelectric development on beluga whales of the Nelson River estuary in Manitoba. Background information is provided on the estuary, beluga whales and their use of arctic and subarctic estuaries, and hydroelectric development on the Nelson River. Potential impacts of such development on the whales are reviewed in the categories of direct effects of changes in physical-chemical conditions (temperature and discharge), indirect effects of disturbances mediated through the food chain, and effects on socioeconomic conditions that may affect beluga whales. Since the biology of beluga whales and other phenomena of interest in this study are poorly known, recommendations are made for research and monitoring activities in the Nelson River estuary. In general, the workshop participants felt that changes in the estuary due to hydroelectric development would not be large enough to affect beluga whales strongly. 34 refs., 1 fig

    Recent dramatic expansion of the natural gas industry in the Western Canada Sedimentary Basin provided ample proof of the potential of this area for further development of natural gas supply. However, the inherent competitive advantages provided by the Western Canada Sedimentary Basin were said to have been offset by low netback prices resulting in poor producer economics when competitiveness is measured by availability of opportunities to find and develop gas supply at costs low enough to ensure attractive returns. Technology was identified as one of the key elements in improving basin competitiveness, but the greatest potential lies in reduced transportation costs and increased access to North American market centres. 8 figs

    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.

    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

    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.)

    A brief history is presented of Canadian uranium exploration, production, and sales. Statistics show that Canada is a good customer for its own uranium due to a rapidly expanding nuclear power program. Due to an average 10 year lag between commencement of exploration and production, and with current producers sold out through 1985, it is imperative that exploration efforts be increased.

    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)

    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

  14. 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.

  15. Evaluation of U.S. Geological Survey Monitoring-well network and potential effects of changes in water use, Newlands Project, Churchill County, Nevada

    Maurer, Douglas K.; Seiler, Ralph L.; Watkins, Sharon A.

    2004-01-01

    Domestic wells tapping shallow ground water are an important source of potable water for rural residents of Lahontan Valley. For this reason, the public has expressed concern over the acquisition of water rights directed by Public Law 101-618. The acquisition has resulted in removal of land from irrigation, which could cause shallow domestic wells to go dry and adversely affect shallow ground-water quality. Periodic water-level measurements and water-quality sampling at a monitoring-well network developed by the U.S. Geological Survey (USGS) provided data to evaluate the potential effects of changes in water use. The USGS, in cooperation with Churchill County, analyzed these data and the monitoring-well network to determine if the network provides an adequate means to measure the response of the shallow aquifer to changes in water use, and to determine if measurable changes have taken place. To evaluate the USGS monitoring-well network, wells were characterized by their distance from active canals or ditches, and from currently (2003) or formerly irrigated land. An analysis of historical data showed that about 9,800 acres of land have been removed from irrigation, generally from the late 1990's to 2003. Twenty-five wells in the network are within about 1 mile of fields removed from irrigation. Of the 25 wells, 13 are within 300 feet of canals or ditches where seepage maintains stable water levels. The 13 wells likely are not useful for detecting changes caused by reductions in irrigation. The remaining 12 wells range from about 400 to 3,800 feet from the nearest canal and are useful for detecting continued changes from current reductions in irrigation. The evaluation showed that of the 75 wells in the network, only 8 wells are likely to be useful for detecting the effects of future (after 2003) reductions in irrigation. Water levels at most of the monitoring wells near irrigated land have declined from 1998 to 2003 because of drought conditions and below normal

  16. Natural gas resources in Canada

    International Nuclear Information System (INIS)

    Meneley, R.A.

    2001-01-01

    Natural gas is an important component in many of the technologies aimed at reducing greenhouse gas emissions. In order to understand the role that natural gas can play, it is important to know how much may be present, where it is, when can it be accessed and at what cost. The Canadian Gas Potential Committee has completed its second report 'Natural Gas Potential in Canada - 2001' (CGPC, 2001). This comprehensive study of exploration plays in Canada addresses the two issues of 'how much may be present' and 'where is it'. The Report deals with both conventional gas and non-conventional gas. One hundred and seven Established Conventional Exploration Plays, where discoveries of gas exist, have been assessed in all of the sedimentary basins in Canada. In addition, where sufficient information was available, twelve Conceptual Exploration Plays, where no discoveries have been made, were assessed. Sixty-five other Conceptual Plays were described and qualitatively ranked. An experienced volunteer team of exploration professionals conducted assessments of undiscovered gas potential over a four-year period. The team used technical judgment, statistical techniques and a unique peer review process to make a comprehensive assessment of undiscovered gas potential and estimates of the size of individual undiscovered gas accumulations. The Committee assessed all gas in place in individual exploration plays. For Established Plays, estimates of Undiscovered Nominal Marketable Gas are based on the percentage of the gas in place that is marketable gas in the discovered pools in a play. Not all of the Nominal Marketable Gas will be available. Some underlies areas where exploration is not possible, such as parks, cities and other closed areas. Some will be held in gas pools that are too small to be economic and some of the pools will never be found. In some areas no production infrastructure will be available. Detailed studies of individual exploration plays and basins will be required

  17. Fusion energy and Canada's role

    International Nuclear Information System (INIS)

    Drolet, T.S.

    1992-01-01

    Fusion is the process of releasing energy from matter which occurs in our sun. Canada is contributing to the development of technology which will permit this process to be harnessed and made available on earth. The international effort has increased from a modest beginning in the 1950s to a level of approximately two billion dollars annually in the 1980s. The purpose of this booklet is to introduce the concept of fusion energy as a technology which should make an important addition to the mix of energy sources for our future. Through a co-ordinated approach, Canada has established several projects which will contribute significantly to the development of technologies in specific areas leading to opportunities now for Canadian industry in the international effort

  18. Environmental radioactivity in Canada 1986

    International Nuclear Information System (INIS)

    1987-01-01

    The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. During 1986 the program was strongly influenced by radioactive fallout on Canada resulting from the Chernobyl nuclear reactor accident on April 26, 1986 in the Soviet Ukraine. The Environmental Radiation Hazards Division (ERHD) increased its frequency of analyses of environmental samples immediately following the accident. Interim screening limits for foodstuffs were developed. A measurement program for radioactivity in domestic and imported foods was implemented. The ERHD measurement program was supplemented by additional measurements conducted by many other private and government laboratories. Radiation doses to Canadian from Chernobyl fallout were extremely low with no group in the population receiving more than 10 microsieverts

  19. Nuclear criticality safety in Canada

    International Nuclear Information System (INIS)

    Shultz, K.R.

    1980-04-01

    The approach taken to nuclear criticality safety in Canada has been influenced by the historical development of participants. The roles played by governmental agencies and private industry since the Atomic Energy Control Act was passed into Canadian Law in 1946 are outlined to set the scene for the current situation and directions that may be taken in the future. Nuclear criticality safety puts emphasis on the control of materials called special fissionable material in Canada. A brief account is given of the historical development and philosophy underlying the existing regulations governing special fissionable material. Subsequent events have led to a change in emphasis in the regulatory process that has not yet been fully integrated into Canadian legislation and regulations. Current efforts towards further development of regulations governing the practice of nuclear criticality safety are described. (auth)

    Despite all the current difficulties, previous erroneous forecasts and other mistakes, the longer term future looks good for uranium mining and for Canada's industry in particular. Saskatchewan continues to offer the most exciting new prospects, the huge and fabulously high grade Cigar Lake deposits being the most spectacular of the recent discoveries. Notwithstanding continuous mining for 30 years from Elliot Lake there still remain there significant uncommitted reserves which can be developed when the market for uranium is in better balance

    The author argues that the nuclear debate in Canada is concerned less with the safety of nuclear power plants and more with arguments of economics and social decision-making. The nuclear industry cannot afford to neglect the continuing need to inform the public about nuclear risks. But there is also a need to develop specific arguments to increase public acceptance of nuclear energy as an economic, democratic and equitable energy option

  6. Overview of Canada's uranium industry

    International Nuclear Information System (INIS)

    Lowell, A.F.

    1982-06-01

    This paper places Canada's uranium industry in its international context. Most uranium, except that produced in the United States, is traded internationally. A brief history of the industry worldwide is given to show how the principal producing areas have fared to date. The industry is young, highly cyclical, and still far from achieving stability. Uranium is a single end-use commodity, entirely dependent on the generation of electricity in nuclear stations, and is without price elasticity: lowering the price does not increase demand. The typical nuclear fuel processing chain has not encouraged or led to much vertical integration. Uranium is subject to more governmental control than any other commodity. The principal market is located in the industrial countries of western Europe, the United States, Canada, and the far east. The uranium supply-demand situation is reviewed, including the current and near-term oversupply and the longer term outlook to 1995. The major negative impact of reactor cancellations and deferments in the United States is discussed. Because of the difficulty in getting reactors on line, it has become easier to forecast the demand for uranium over the next 10 years. It is more difficult to predict how that demand will be met from the more than ample competing sources. Canada's potential for supplying a significant portion of this demand is considered in relation to producers and potential new producers in other countries

  7. Women in Physics in Canada

    Science.gov (United States)

    McKenna, Janis

    2012-10-01

    Here we are in the 21st century in Canada, where most of us would say that young girls and boys have equal access to education, opportunities, and careers of their own choice. In Canada, women currently outnumber men in full-time university enrollment, in Medical Schools and in Law Schools. 48% of the Canadian work force is female, yet women make up only 21% of working professionals in science, engineering and technology. Canada-wide in Physics, the situation is such that only 20% of our BSc graduates are women, and 19% of our PhD graduates are women. It is evident that the ``leaky pipeline'' in Physics leaks most at a young age, before BSc graduation. High school physics statistics in BC indicate that while most of the grade 12 science and math disciplines have roughly equal numbers of young men and women enrolled, this is not the case for high school physics, where province-wide, only 30% of Physics 12 students are women. (Biology is also skewed, but in the other direction: 62% of Biology 12 students are women) This poster will present current statistics and will hopefully be a wake-up call for us all to consider participating in more outreach in science, and especially physics, in our high schools.

  8. Natural gas potential in Canada

    International Nuclear Information System (INIS)

    1997-01-01

    An independent assessment of the undiscovered gas potential in Canada was conducted by a group of volunteer geoscientists. This report is the first of a series of assessments that are planned to be issued every three to four years. Separate assessments were made of conventional gas resources, unconventional gas resources and frontier gas resources. The assessment for conventional gas resources was organized into three categories: (1) gas producing areas where new discoveries can be integrated into existing producing and transportation infrastructure, (2) frontier basins where gas discoveries have been made, but no production is currently underway, and (3) frontier areas where gas-containing sedimentary rocks are known to exist, but where no gas discoveries have been made to date. The committee used year-end 1993 reserves data from discovered pools in each exploration play to predict the undiscovered potential. Information about discovered pools, geological setting, geographic limits and pool sizes of undiscovered pools in each exploration play was provided. Results of the investigation led to the conclusion that the natural gas potential in Canada is in fact larger than hitherto expected. It was estimated that in the Western Canada Sedimentary Basin 47 per cent of the total volume of conventional gas is yet to be discovered. 152 figs

  9. Canada's helium output rising fast

    Energy Technology Data Exchange (ETDEWEB)

    1966-12-01

    About 12 months from now, International Helium Limited will be almost ready to start up Canada's second helium extraction plant at Mankota, in Saskatchewan's Wood Mountain area about 100 miles southwest of Moose Jaw. Another 80 miles north is Saskatchewan's (and Canada's) first helium plant, operated by Canadian Helium and sitting on a gas deposit at Wilhelm, 9 miles north of Swift Current. It contains almost 2% helium, some COD2U, and the rest nitrogen. One year in production was apparently enough to convince Canadian Helium that the export market (it sells most of its helium in W. Europe) can take a lot more than it's getting. Construction began this summer on an addition to the Swift Current plant that will raise its capacity from 12 to 36MMcf per yr when it goes on stream next spring. Six months later, International Helium's 40 MMcf per yr plant to be located about 4 miles from its 2 Wood Mountain wells will double Canada's helium output again.

  10. Indigenous Educational Attainment in Canada

    Directory of Open Access Journals (Sweden)

    Catherine E. Gordon

    2014-06-01

    Full Text Available In this article, the educational attainment of Indigenous peoples of working age (25 to 64 years in Canada is examined. This diverse population has typically had lower educational levels than the general population in Canada. Results indicate that, while on the positive side there are a greater number of highly educated Indigenous peoples, there is also a continuing gap between Indigenous and non-Indigenous peoples. Data also indicate that the proportion with less than high school education declined, which corresponds with a rise of those with a PSE; the reverse was true in 1996. Despite these gains, however, the large and increasing absolute numbers of those without a high school education is alarming. There are intra-Indigenous differences: First Nations with Indian Status and the Inuit are not doing as well as non-Status and Métis peoples. Comparisons between the Indigenous and non-Indigenous populations reveal that the documented gap in post-secondary educational attainment is at best stagnant. Out of the data analysis, and based on the history of educational policy, we comment on the current reform proposed by the Government of Canada, announced in February of 2014, and propose several policy recommendations to move educational attainment forward.

    Prospectors and Developers Association of Canada Mining Matters is a charitable organization whose mandate is to bring the wonders of Canada's geology and mineral resources to students, educators and industry. The organization provides current information about rocks, minerals, metals, and mining and offers exceptional educational resources, developed by teachers and for teachers that meet Junior, Intermediate and Senior Provincial Earth Science and Geography curriculum expectations. Since 1994, Mining Matters has reached more than 400,000 educators, students, industry representatives, and Aboriginal Youth through Earth Science resources. At the time of the program's inception, members of the Prospectors and Developers Association of Canada (PDAC) realized that their mining and mineral industry expertise could be of help to teachers and students. Consulting experts in education, government, and business, and the PDAC worked together to develop the first Mining Matters Earth Science curriculum kit for Grades 6 and 7 teachers in Ontario. PDAC Mining Matters became the official educational arm of the Association and a charitable organization in 1997. Since then, the organization has partnered with government, industry, and educators to develop bilingual Earth science teaching units for Grades 4 and 7, and senior High School. The teaching units consist of kits that contain curriculum correlated lesson plans, inform bulletins, genuine data sets, rock and mineral samples, equipment and additional instructional resources. Mining Matters offers instructional development workshops for the purposes of training pre-service and in- service educators to use our teaching units in the classroom. The workshops are meant to provide teachers with the knowledge and confidence they need to successfully employ the units in the classroom. Formal mechanisms for resource and workshop evaluations are in place. Overwhelmingly teacher feedback is positive, describing the excellence

    We analyzed characteristics of wetland habitats used by breeding black scoters (Melanitta nigra) and surf scoters (M. perspicillata) in the eastern boreal forest and subarctic regions of Canada based on satellite telemetry data collected in the spring and summer. During 2002 and 2004, nine black scoters (four males, five females) were tracked to breeding areas in Quebec, Manitoba, and Northwest Territories. In addition, in 2001?04, seven surf scoters (three males, four females) were tracked to breeding areas in Labrador, Quebec, Northwest Territories, and Nunavut. Based on satellite telemetry data, locations of black and surf scoters in breeding areas were not significantly different in regard to latitude and longitude. Presumed breeding areas were manually plotted on topographic maps and percent cover type and water were estimated. Breeding habitat of black scoters was significantly different than that for surf scoters, with black scoters mainly using open (tundra) areas (44%) and surf scoters using mainly forest areas (66%). Surf scoters presumed breeding areas were at significantly higher elevations than areas used by black scoters. Some breeding areas were associated with islands, but the role of islands for breeding areas is equivocal. These results aid in the identification of potentially critical breeding areas and provide a baseline classification of breeding habitats used by these two species.

    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.

    Energy Technology Data Exchange (ETDEWEB)

    1990-01-01

    A summary is presented of Canada's Green Plan, a comprehensive action plan to ensure a healthy environment for the future. The plan defines targets and schedules which will drive federal environmental initiatives, and incorporates concepts of sustainable development. Elements of the plan include initiatives to combat and prevent water pollution; control ocean dumping; control smog-causing emissions; provide tighter air pollution standards; provide for sound waste management according to the principles of reduce, reuse, recycle, and recover; assess and control chemical wastes; sustain Canadian forests and maintain their diversity while shifting forest management from sustained yield to sustainable development; maintain and enhance environmental sustainability in the agro-food sector and the fishery sector; preserve and protect national parks and wildlife; and preserve and enhance the integrity, health, biodiversity and productivity of Arctic ecosystems. With respect to global-scale problems, measures will be taken to stabilize greenhouse gas emissions, limit acid rain-related emissions, and phase out the use of ozone-depleting substances. The plan also intends to improve Canada's capability to respond to environmental emergencies, improve environmental decision-making by strengthening and building of partnerships, promote environmental science research and development, and make effective and balanced use of enviromental laws, with market-based approaches for environmental protection.

    Recruitment drive for nurse gradutates British Columbia (BC), the westernmost Canadian province, urgently needs 1,500 qualified nurses graduates to staff longterm care and assisted-living beds as well as home care clients. The provincial government has launched a $160,000 (£78,600) marketing campaign called BC Cares. Craig Hebert, dean of development and access training at Northern Lights College in BC, said: 'The industry needs to get the message out to students that there has never been a better time to start a career in senior health care. Graduates who study for about one year, sometimes less, will have their pick of jobs in a number of service environments and can advance relatively quickly to the nursing profession.'

  18. Landfill gas management in Canada

    International Nuclear Information System (INIS)

    David, A.

    1997-01-01

    Landfill gas produced from solid waste landfills is one of the most significant sources of anthropogenic methane in Canada. Methane, a potent greenhouse gas, is 24.5 times more powerful than carbon dioxide by weight in terms of global climate change. Landfill gas recovery plays an important role in Canada's commitment to stabilize greenhouse gas emissions at 1990 levels by the year 2000 under the United Nations Framework Convention on Climate Change. Landfill gas is a potentially harmful emission that can be converted into a reliable environmentally-sustainable energy source used to generate electricity, fuel industries and heat buildings. The recovery and utilization of landfill gas is a win-win situation which makes good sense from local, regional and global perspectives. It provides the benefits of (1) reducing the release of greenhouse gases that contribute to global warming; (2) limiting odors; (3) controlling damage to vegetation; (4) reducing risks from explosions, fires and asphyxiation; (5) converting a harmful emission into a reliable energy source; and (6) creating a potential source of revenue and profit. Canadian landfills generate about 1 million tons of methane every year; the equivalent energy of 9 million barrels of oil (eight oil super tankers), or enough energy to meet the annual heating needs of more than half a million Canadian homes. Currently, twenty-seven facilities recover and combust roughly 25% of the methane generated by Canadian landfills producing about 3.2 PJ (10 15 Joules) of energy including 80 MW of electricity and direct fuel for nearby facilities (e.g., cement plants, gypsum board manufacturers, recycling facilities, greenhouses). This paper reviews landfill gas characteristics; environmental, health and safety impacts; landfill gas management in Canada; the costs of landfill gas recovery and utilization systems; and on-going projects on landfill gas utilization and flaring

  3. An Energy Strategy for Canada

    Directory of Open Access Journals (Sweden)

    Michal C. Moore

    2015-10-01

    Full Text Available Canada is struggling to fully develop, sell and move its energy resources. This is a dramatic change from the recent past where the U.S. has provided stable growth in demand for energy supplied by the provinces, from hydrocarbons to electricity. Current circumstances now challenge this relationship, adding environmental, policy and economic hurdles that exacerbate the impact of fluctuations in world demand and pricing. In addition, competitive interaction between provinces, aboriginal land owners and special interest groups complicate and compound the issues of royalty returns, regulatory authority and direction, land-use management and long-term market opportunities for Canadian companies. There is no strategic document guiding the country’s energy future. As the steward of one of the largest, most diverse and valuable energy "banks" in the world, Canada has a unique opportunity to exploit a critical and valuable economic niche in the world economy. Given the lack of federal leadership and the tendency for each province to undercut each other in the same marketplace, there is also the distinct possibility the nation will squander the opportunity. This document offers the rationale for a comprehensive energy strategy, literally a vision where Canada can lead and not follow opportunities in energy markets. This strategic approach to energy systems by definition will include transportation, housing, employment and financial markets. It is not a plan, not a foil for tax or policy guidance in one or more sectors. This strategy is a fundamental rail on which plans, tactics and policies can be built. This vision identifies how the provinces can work together using all the tools available to them, maximizing long-term resource development while minimizing environmental damage. This document assumes there can be a broad commitment and effort by the federal government to help build those tools, providing guidance and assistance where needed without

    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

    Full Text Available Under Canada's four-year, $136 million Family Violence Initiative, the federal government is calling upon all Canadians to work in partnerships towards the elimination of family violence - child abuse, violence against women, and elder (senior abuse. Family violence is a complex problem and requires the efforts of all Canadians to resolve it. One of the key themes of the Initiative - a multidisciplinary approach to the problem of family violence - is reflected in the selection and development of projects. Activities funded by the seven federal departments and agencies involved in the Initiative emphasize partnerships with the professional, voluntary, corporate, non-government and government sectors.

    The structure of capital costs during NPP construction in Canada is considered. Capital costs comprise direct costs (cost of the ground and ground rights, infrastructure, reactor equipment, turbogenerators, electrotechnical equipment, auxiliary equipment), indirect costs (construction equipment and services, engineering works and management services, insurance payments, freight, training, operating expenditures), capital per cents for the period of construction and cost of heavy water storages. It proceeds from the analysis of the construction cost structure for a NPP with the CANDU reactor of unit power of 515, 740 and 880 MW, that direct costs make up on the average 62%

  11. Relative spatial soil geochemical variability along two transects across the United States and Canada

    2009-01-01

    To support the development of protocols for the proposed North American Soil Geochemical Landscapes project, whose objective is to establish baselines for the geochemistry of North American soils, two continental-scale transects across the United States and Canada were sampled in 2004. The sampling employed a spatially stratified random sampling design in order to estimate the variability between 40-km linear sampling units, within them, at sample sites, and due to sample preparation and analytical chemical procedures. The 40-km scale was chosen to be consistent with the density proposed for the continental-scale project. The two transects, north–south (N–S) from northern Manitoba to the USA–Mexico border near El Paso, Texas, and east–west (E–W) from the Virginia shore north of Washington, DC, to north of San Francisco, California, closely following the 38th parallel, have been studied individually. The purpose of this study was to determine if statistically significant systematic spatial variation occurred along the transects. Data for 38 major, minor and trace elements in A- and C-horizon soils where less than 5% of the data were below the detection limit were investigated by Analysis of Variance (ANOVA). A total of 15 elements (K, Na, As, Ba, Be, Ce, La, Mn, Nb, P, Rb, Sb, Th, Tl and W) demonstrated statistically significant (p<0.05) variability at the between-40-km scale for both horizons along both transects. Only Cu failed to demonstrate significant variability at the between-40-km scale for both soil horizons along both transects.

    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.

  14. Nuclear emergency preparedness in Canada

    International Nuclear Information System (INIS)

    1993-03-01

    The preparedness of utilities and government agencies at various levels for dealing with nuclear emergencies occurring at nuclear reactors in Canada is reviewed and assessed. The review is centered on power reactors, but selected research reactors are included also. Emergency planning in the U.S.A., Germany and France, and international recommendations on emergency planning are reviewed to provide background and a basis for comparison. The findings are that Canadians are generally well protected by existing nuclear emergency plans at the electric utility and provincial levels but there are improvements that can be made, mainly at the federal level and in federal-provincial coordination. Ten issues of importance are identified: commitment to nuclear emergency planning by the federal government; division of federal and provincial roles and responsibilities; auditing of nuclear emergency preparedness of all levels of government and of electric utilities; the availability of technical guidance appropriate to Canada; protective action levels for public health and safety; communication with the public; planning and response for the later phases of a nuclear emergency; off-site exercises and training; coordination of international assistance; and emergency planning for research reactors.

    1999-10-01

    All wells drilled in Western Canada during the first nine months of 1999 are listed and sorted into 12 geographical areas used in the Petroleum Services Association of Canada (PSAC) well cost study. Each area represents wells of common drilling, production and depth characteristics. Area totals for well counts and meters drilled were determined from the sorting process. Previous years' activities are reviewed and various operators and PSAC members contacted to review upcoming programs. In addition, trends and other projections were consulted to develop an estimate of drilling activity for the rest of 1999 as well as a projection of drilling activity for 2000. The historical and projected drilling activities were tabulated and plotted for each area. Average drilling costs for each area were determined, and the total expenditures were calculated for each area by multiplying the the projected meterage by the adjusted drilling costs. All costs were allocated to various services and products utilizing percentages determined in the Well Cost Study. During the sorting process, a list was developed of the major operators in each area, which list is included in the report along with average depths and types of wells drilled by the various operators in each area. The costs included in the report include only drilling and completion operations, starting with the building of the location prior to drilling, and ending with the installation of the wellhead after construction. 5 tabs

    Grasty, R.L.; Carson, J.M.; Charbonneau, B.W.; Holman, P.B.

    1984-01-01

    Published airborne gamma ray survey data from 33 areas of Canada were used to compile information on the average ground level exposure from natural radiation. The exposures at ground level were calculated from the surface concentrations of potassium, uranium and thorium. The highest levels of radioactivity were found in northern Canada and were generally related to granitic rocks; the lowest levels with the Athabasca sandstone. Summer outdoor exposure rates have a population-weighted average of 3.7 +- 2.3 μR.h -1 , of which 48 percent orginated from potassium, 43 percent from the thorium series and 9 percent from the uranium series. This low level of radioactivity, compared to worldwide data, has resulted from erosion of a geologically old continental crust in which radioactivity decreases with depth. When seasonal variations of soil moisture and snow cover are considered, the annual population-weighted average outdoor exposure rate decreases to 2.8 +- 1.7 μR.h -1 corresponding to an annual outdoor dose-equivalent of 150 +- 90 μSV. Factors increasing the annual outdoor dose-equivalent are cosmic radiation (320 +- 30 μSV) and the internal radioactivity of the body (190 μSV). Using the ratio between indoor and outdoor values for worldwide published data, the average annual Canadian whole-body dose-equivalent from all sources of natural radiation is estimated to be 690 +-130 μSV

    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

  18. Energy in Canada: An overview

    International Nuclear Information System (INIS)

    Cameron, G.W.

    1991-01-01

    Recent changes in the North American natural gas industry are discussed, with a focus on how these changes will affect the ability of Alberta and Canadian natural gas supply to meet market growth. These changes include a decline in the merchant role of many of the major interstate pipelines, resulting in a larger number of smaller-sized purchasers for natural gas marketers to deal with; a greater extent of direct purchasing by local distribution companies and large industrial users, combined with a preference for spot sales rather than long-term commitments; direct marketing of uncontracted gas by many producers and brokers; a bidding type of sales process rather than a negotiated process; and price deregulation. It is foreseen that long term security of supply will again become an important factor to North American buyers, and Canada can offer substantial supplies under secure long term contracts. Marketers will have to seek new market targets such as cogeneration plants and the transportation sector. Access to pipeline transport will be one of the major factors in obtaining new markets. The Canada-USA free trade agreement is viewed as a positive development which should help Canadian gas marketers to gain and retain U.S. customers

    Snodin, H.

    2007-01-01

    This study reported on wind turbine supplies to the Canadian market. The report was written to address concerns for Canada's supply outlook in the near future due to the booming wind energy market. Turbine shortages have arisen as a result of continued growth in both European and North American markets. Long lead-times on turbine orders are now increasing the pressure to lock in turbine supply during the initial phases of the development process. Future growth of the wind energy industry will be impacted if turbine supply difficulties continue to contribute to uncertainties in the development process. The report provided an overview of the North American and global wind energy markets, as well as a summary of telephone interviews conducted with turbine suppliers. The implications for the future of turbine supply to the Canadian market were also analyzed. It was concluded that policy-makers should focus on supporting the expansion of manufacturing facilities for small wind turbines and control infrastructure in Canada 7 refs., 3 figs

    A search for solar gamma-rays in the energy range 10 MeV and greater was made by measuring the angular distribution of the flux from the direction of the sun using a stack of oriented nuclear emulsions flown by balloon on July 21, 1974, from Fort Churchill, Manitoba, Canada. The emulsion plates were scanned for the electron-positron pairs. An upper limit to the flux of solar gamma-rays, for a 90% statistical confidence level, was estimated to be 3.1 x 10 -4 photons cm -2 s -1 in the energy region above 10 MeV. On the day of the flight the sun spot number (Rsub(z)) was 55, and no major solar flares were reported. (orig.) [de

    DEFF Research Database (Denmark)

    Beatty, Gemma, E.; Philipp, Marianne; Provan, Jim

    2010-01-01

    hybridization may lead to the extinction of peripheral populations of P. minor where the two species grow sympatrically. Extinction could occur as a result of genetic assimilation where F1s are fertile, or via the removal of unidirectionally pollinated sterile F1s, or by a combination of these processes......Aim Introgressive hybridization between a locally rare species and a more abundant congener can drive population extinction via genetic assimilation, or the replacement of the rare species gene pool with that of the common species. To date, however, few studies have assessed the effects...... of such processes at the limits of species' distribution ranges. In this study, we have examined the potential for hybridization between range-edge populations of the wintergreen Pyrola minor and sympatric populations of Pyrola grandiflora.

Thelife tables were constructed using the Chiang Method based on the adjusted dataon deaths and population by age and sex from the Indian Registry, maintainedby the Department of Indian Affairs and Northern Development, Government ofCanada. The data on the register are subjected to late reported and non reportedvital events. At the Canada level, life expectancy at birth for Registered Indianmales was 59.9 years in 1976-1980, rising to 68.3 years in 1996-2000. Forfemales, the life expectancy at birth was relatively higher, 66.6 years in 1976-80,and 74.5 years in 1996-2000. The recent life expectancies at birth forRegistered Indians are comparable to those observed for the total Canadian maleand female populations during the period 1960-1962 at 68.4 and 74.3 years. In1999, life expectancy at birth for the total Canadian population was reported to be 76.3 years formales and 81.7 years for females. The life expectancy at birthfor the Registered Indians in the Eastern region was higher than for those in theWestern region. The pattern of regional variation in life expectancy at birth forthis population seems to be the reverse of the regional variation for the totalCanadian population.FrenchCe document présente les analyses des nouvelles estimations des tables desurvie abrégées comprenant l’espérance de vie à la naissance, l’estimation deleur variance et la limite de confiance selon le sexe pour les Indiens inscrits auCanada et dans 2 grandes régions (Est : Atlantique, Québec, Ontario etManitoba; et

    The Canadian electrical industry can expect to grow more muscle in 1967. Demand for electricity increases across the country and the big power projects will be the Nelson Columbia, Peace, Manicouagan, Outardes and Churchill Falls. With more promotion by utilities scheduled better electrical living will get a record shot in the arm.

    1997-01-01

    A biomass inventory for Canada was undertaken to address the data needs of carbon budget modelers, specifically to provide estimates of above-ground tree components and of non-merchantable trees in Canadian forests. The objective was to produce a national method for converting volume estimates to biomass that was standardized, repeatable across the country, efficient and well documented. Different conversion methods were used for low productivity forests (productivity class 1) and higher productivity forests (productivity class 2). The conversion factors were computed by constructing hypothetical stands for each site, age, species and province combination, and estimating the merchantable volume and all the above-ground biomass components from suitable published equations. This report documents the procedures for deriving the national biomass inventory, and provides illustrative examples of the results. 46 refs., 9 tabs., 5 figs

    1998-01-01

    Natural gas supply and demand trends in Western Canada are reviewed in a series of overhead viewgraphs. Production versus pipeline capacity, required gas well completions in the WCSB to meet local demand and fill export pipeline capacity to year 2005, NYMEX and AECO price trends during 1995-2000, and the question of what will happen to prices with additional pipeline capacity to the U.S. Midwest were summarized. The best guess is that Midwest prices will need to be high enough to attract marginal supplies from the Gulf, i.e. prices have be around the Henry Hub + five cents/ mmbtu. The new Canadian pipelines, (Northern Border and Alliance) will lower Midwest prices somewhat, but the impact will be modest. Assuming that additional planned pipeline expansion come on-stream, the pressure to expand east of Chicago will be considerable. tabs., figs

    Energy Technology Data Exchange (ETDEWEB)

    Admas, P [ed.; Johnson, P G [ed.

    1988-01-01

    A conference was organized in Canada to allow a large number of students with northern interests to meet together to present the results of their work and to discuss many other matters of mutual interset. In addition, this conference allowed students from many disciplines in the natural and social sciences to advance northern scholarship, and to foster a multidisciplinary approach to northern studies. A wide range of topics from the physical, biological, and social sciences were covered, including Inuit music, traditional medicine, mammoth bones, fossil trees, icebreaker design, archaeology, caves, naturally acid and other lakes, glaciers, bogs, Inuit clothing, education, northern parks, river ice jams, geology, marine science including large marine mammals, and global strategy. Separate abstracts have been prepared for twelve papers from this conference.

    The practice followed in planning, preparing and conducting offsite nuclear emergency exercises in the Province of Ontario, Canada, is described. In addition, some of the main issues that arise during this process are discussed, as well as Canadian experience in dealing with them. The planning process starts with basic decisions on the aim, scope and duration of the exercise. It proceeds through selection of the exercise objectives and participants, the development of scenarios and incident lists culminating in a master scenario and a master incident list, and finally, the production of control inputs. Preparations include the setting up of a planning organization, making arrangements for exercise control and evaluation, and the required logistics. Some aspects of international exercises are also covered, based upon experience with joint exercises with the U.S.A

    2009-11-15

    Bernanke [Bernanke, Ben S. Irreversibility, uncertainty, and cyclical investment. Quarterly Journal of Economics 98 (1983), 85-106.] shows how uncertainty about energy prices may induce optimizing firms to postpone investment decisions, thereby leading to a decline in aggregate output. Elder and Serletis [Elder, John and Serletis, Apostolos. Oil price uncertainty.] find empirical evidence that uncertainty about oil prices has tended to depress investment in the United States. In this paper we assess the robustness of these results by investigating the effects of oil price uncertainty in Canada. Our results are remarkably similar to existing results for the United States, providing additional evidence that uncertainty about oil prices may provide another explanation for why the sharp oil price declines of 1985 failed to produce rapid output growth. Impulse-response analysis suggests that uncertainty about oil prices may tend to reinforce the negative response of output to positive oil shocks. (author)

  12. What fusion means to Canada

    International Nuclear Information System (INIS)

    Bolton, R.A.

    1983-06-01

    Fusion can and will play an ever-increasing role in the energy balance once it has been brought on line. Taming of this technology and the maturing processes of engineering and economic feasibility will proceed at a rate which depends very strongly upon international and collective national wills to see it through. Large experimental devices, particularly of the tokamak type, are now being completed; their performance should give a very good idea of the scientific feasibility. The next-stage devices are at the pre-proposal and proposal stages but are not yet approved, even in principle. An improved general economic climate sustained for a few years would certainly help re-establish the momentum of world international efforts in fusion. This paper gives an overview of fusion research on a world scale and details of the particular aspects that Canada has chosen to pursue

    Dawson, K.

    1994-01-01

    The current consensus on climatic change in Canada is briefly summarized, noting the results of modelling of the effects of a doubling of atmospheric CO 2 , the nonuniformity of climate change across the country, the uncertainties in local responses to change, and the general agreement that 2-4 degrees of warming will occur for each doubling of CO 2 . Canadian government response includes programs aimed at reducing the uncertainties in the scientific understanding of climate change and in the socio-economic response to such change. Canadian climate change programs include participation in large-scale experiments on such topics as heat transport in the ocean, and sources and sinks of greenhouse gases; development of next-generation climate models; studying the social and economic effects of climate change in the Great Lakes Basin and Mackenzie River Basin; investigation of paleoclimates; and analysis of climate data for long-term trends

    Kobayashi, A

    1988-01-01

    This collection of 5 short essays on Asian migration to Canada focuses on the relationships between individual migrants and their social contexts, both Asian and Canadian. Papers by Anderson and Kobayashi adopt research perspectives of outsider and insider, respectively. Vibert provides a historical overview against which the substantive issues introduced in the other 3 papers can be understood, and he illustrates the links between circumstances of migration and the larger issues by which the course of Canadian social progress has been steered. Mercer provides an introduction to issues that dominate the agenda of contemporary research, to show that Canadian communities of Asian heritage continue to grow in size, diversity, and complexity, as they become more established on the Canadian landscape. This collection is as much about the geography of racism as it is about migration.

    Eltony, M.N.

    1993-01-01

    This paper provides an estimate of household gasoline demand in Canada by applying a detailed model to pool time-series (1969-1988) and cross-sectional provincial data. The model recognises three major behavioural changes that households can make in response to gasoline price changes: drive fewer miles, purchase fewer cars, and buy more fuel-efficient vehicles. In the model, fuel economy is treated in considerable detail. The two components of the fuel economy of new cars sold-the technical fuel efficiency of various classes of cars and the distribution of new car sales according to their interior volume rather than their weight - are estimated as functions of economic variables. Car manufacturers are assumed to improve the technical fuel economy according to their expectation of consumer's response to future changes in gasoline prices and general economic conditions.

    Wilson, Robin J; Huculak, Bria; McWhinnie, Andrew

    2002-01-01

    As many jurisdictions move towards more retributive measures as a means to address public discontent with crime, a parallel movement has developed in regard to restorative justice. This article presents three restorative initiatives currently in use in Canada. Each initiative addresses offender behavior and community engagement at a different point in the justice continuum. The use of Sentencing Circles is an example of how restorative justice principles can be instituted at the front end, prior to an offender becoming lodged in the system. The Restorative Justice Options to Parole Suspension project demonstrates how community engagement can assist in preventing offenders from being returned to the system once they have achieved conditional release. The Circles of Support and Accountability project has enlisted the support of professionally supported volunteers in the community reintegration of high-risk sexual offenders. These initiatives are presented within a framework of effective correctional interventions and increased empowerment for a variety of stakeholders. Copyright 2002 John Wiley & Sons, Ltd.

    1991-01-01

    The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. Following major changes to the CAMECO Port Hope operations to reduce uranium emissions, a study was initiated to measure uranium levels in air in the community. Studies continued on lung cancer and domestic exposure to radon, and current levels of cesium-137 in caribou, a major source of food in northern communities. The movement of tritium on the Ottawa and St. Lawrence rivers was studied following an accidental release into the Ottawa River. Monitoring continued of fallout contamination from Chernobyl in imported foods. All measurements recorded during 1988 were below the limits recommended by the International Commission on Radiological Protection. (14 refs., 14 figs., 15 tabs.)

  18. Canada's population: growth and dualism.

    Science.gov (United States)

    Beaujot, R P

    1978-04-01

    In Canada the current 1.3% population growth rate is causing some concern. Those concerned argue that such a rate of growth in combination with high levels of consumption could jeopardize the country's resource base and its comfortable style of living. Many Canadians are questioning high levels of immigration, for now that the fertility level is below replacement level, net immigration contributes substantially to population growth (over 1/3 in 1976). The growing proportion of non-Europeans among recent immigrants is causing resentment, and, in a tight job market, immigrants are regarded as threats to the World War 2 baby boom cohort who are now at working ages. The baby boom generation also puts stress on housing and health services, and it will increase the need for pension checks as it ages. Although French fertility is no longer high and immigration is no longer dominated by the British, the French group's 200-year struggle to preserve its identity continues on in the current effort of the Quebec government to enforce the use of French language by law within that province. Geography and climate dictate another demographic fact that divides the country and pervades its history. In addition to intense regionalism, uneven population distribution is responsible for 2 other concerns: the rapid growth of several already large cities and depopulation of many small communities. Focus in this discussion is on Canada's population growth in the past and as projected for the future, historical and current fertility, mortality and immigration trends, the search for a new immigration policy, the impact of the baby boom generation on the population's age structure and the problems this creates, and recent shifts in population distribution and in the country's ethnic and linguistic makeup. The population policy proposals evolved thus far involve to a great extent the use of immigration as a lever for achieving given population objectives.

  19. 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

  20. 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

    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

    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

    1993-12-31

    In June 1992 one of the largest international conferences ever held took place in Rio de Janeiro, Brazil. It was attended by the heads of state of more than 100 countries. The ambitious aim of the United Nations Conference on Environment and Development (UNCED) -- the Earth Summit -- was to try to reconcile the need for global environmental protection with the need for continuing economic development. The purpose of this document is to provide a brief account of the results of Rio and the way Canadians participated. In addition, this document outlines the immediate priorities of the Government of Canada and the actions under way. It is not meant to be a comprehensive response to the entire Rio agenda. Rather, it is intended to report to Canadians on the steps the government has taken so far and, where possible, the direction in which it is headed. On the number of important issues, the government`s plans are well advanced. For example, action is well under way on the Convention on Climate Change, as high-lighted in the Green Plan`s National Action Strategy on Global Warming. On a number of other issues, it is clear that there is work to be done. The government is committed to completing the task through continuing action and leadership.

    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

  8. Rural women caregivers in Canada.

    Science.gov (United States)

    Crosato, Kay E; Leipert, Beverly

    2006-01-01

    Informal caregiving within rural contexts in Canada is increasing. This is due in part to a number of factors related to the restructuring of the Canadian health care system, the regionalization of services to urban locations, the increased population of people 65 years and older, and the desire of this population to age within their rural homes. Most often, the informal caregiving role is assumed by rural women. Women tend to fall into the role of informal caregiver to elders because of the many societal and gender expectations and values that are present within the rural culture. The purpose of this literature review is to identify the context in which women provide care for an elder in rural Canada. Illustrating these issues will help to uncover challenges and barriers rural women face when providing care and highlight recommendations and implications for rural women caregivers and nurses employed within rural settings. Many rural women share similar caregiving experiences as urban informal caregivers, but rural women are faced with additional challenges in providing quality care for an elder. Rural women caregivers are faced with such issues as limited access to adequate and appropriate healthcare services, culturally incongruent health care, geographical distance from regionalized centers and health services, transportation challenges, and social/geographical isolation. In addition to these issues, many rural women are faced with the multiple role demands that attend being a wife, mother, caregiver and employee. The pile up of these factors leaves rural women caregivers susceptible to additional stresses and burn out, with limited resources on which to depend. Through reviewing pertinent literature, appropriate implications and recommendations can be made that may assist rural women caregivers and rural nurses. Nurses working within rural communities are in ideal settings to work collaboratively in building supportive relationships with rural women in order to

    Science.gov (United States)

    2013-01-01

    A society that values mental health and helps people live enjoyable and meaningful lives is a clear aspiration echoed throughout our Canadian health care system. The Mental Health Commission of Canada has put forth a framework for a mental health strategy with goals that reflect the virtue of optimal mental health for all Canadians (Mental Health Commission Canada, 2009). Canadian nurses, the largest group of health care workers, have a vital role in achieving these goals. In Canada, two-thirds of those who experience mental health problems do not receive mental health services (Statistics Canada, 2003). Through a gendered, critical, and sociological perspective the goal of this paper is to further understand how the past has shaped the present state of psychiatric mental health nursing (PMHN). This integrative literature review offers a depiction of Canadian PMHN in light of the intersections of history, gender, education, and quality of nursing work life. Fourteen articles were selected, which provide a partial reflection of contemporary Canadian PMHN. Findings include the association between gender and professional status, inconsistencies in psychiatric nursing education, and the limitations for Canadian nurse practitioners to advance the role of the psychiatric mental health nurse practitioner.

  10. Western Canada drilling cycle optimization

    International Nuclear Information System (INIS)

    2003-06-01

    The oil and gas industry in western Canada operates in annual and seasonal cycles with peak activity periods that require a large skilled labour force for short periods of time. This study examines why seismic and drilling activity is greatest during the first quarter of the year instead of being distributed evenly over the year. The objective of the study was to provide recommendations that would help optimize the industry cycle. The study includes an analysis of historical trends that validate the industry first quarter peaking activity. It also includes interviews with 36 industry representatives and provides insight and validation of trends. The final phase of the report includes recommendations that both industry and governments may wish to implement. The study includes financial, operational and environmental considerations. It was shown that natural gas directed drilling activity is strongly correlated with changes in natural gas prices. In the case of oil drilling activity, peak activity responds to oil prices from the prior quarter. In general, drilling and seismic costs are higher in the winter months because of increased demand for equipment and services. In addition winter drilling operations require a diesel fired boiler to generate steam. 36 refs., 2 tabs., 52 figs

  11. Understanding gasoline pricing in Canada

    International Nuclear Information System (INIS)

    2001-04-01

    This brochure is designed to help consumers understand how gasoline is priced and explained why prices increase, fluctuate and vary by location, city or region. The price of a litre of gasoline reflects the costs of crude oil, refining, retailing and taxes. Taxes are usually the largest single component of gasoline prices, averaging 40 to 50 per cent of the pump price. The cost of crude oil makes up another 35 to 45 per cent of the price. Refining costs make up 10 to 15 per cent while the remaining 5 to 10 per cent represents retail costs. Gasoline retailers make a profit of about 1 cent per litre. The latest network technology allows national and regional retail chains to constantly monitor price fluctuations to change their prices at gasoline stations at a moments notice to keep up with the competition and to protect their market shares. Several government studies, plus the Conference Board of Canada, have reported that competition is working in favour of Canadian motorists. This brochure also explained the drawbacks of regulating crude and pump prices with the reminder that crude prices were regulated in the 1970s with many negative consequences. 2 tabs., 1 fig

  12. Situation awareness system for Canada

    Hill, Andrew

    1999-07-01

    Situation awareness encompasses a knowledge of orders, plans and current knowledge of friendly force actions. Knowing where you are and being able to transmit that information in near real-time to other friendly forces provides the ability to exercise precise command and control over those forces. With respect to current command and control using voice methods, between 40 percent and 60 percent of Combat Net Radio traffic relates to location reporting of some sort. Commanders at Battle Group and below spend, on average, 40 percent of their total time performing position and navigation related functions. The need to rapidly transfer own force location information throughout a force and to process the received information quickly, accurately and reliably provides the rationale for the requirement for an automated situation awareness system. This paper describes the Situation Awareness System (SAS) being developed by Computing Devices Canada for the Canadian Department of National Defence as a component of the Position Determination and Navigation for Land Forces program. The SAS is being integrated with the Iris Tactical Command, Control, Communications System, which is also being developed by Computing Devices. The SAS software provides a core operating environment onto which command and control functionality can be easily added to produce general and specialist battlefield management systems.

    1992-01-01

    After three years of evaluating prospects and negotiating with government and industry representatives, Gulf Canada established its first joint venture in the Russian Federation with Komineft, a production association from the Komi autonomous republic. Komineft has a 50% share of the venture, and the rest is shared equally between Gulf and British Gas. The operating area is at the Vozey and Upper Vozey fields in the Timan-Pechora Basin, some 1,500 km northeast of Moscow just inside the Arctic Circle. An attractive feature of the Upper Vozey project is low development costs of ca $2/bbl. In the Vozey field, the venture will set up an enhanced oil recovery demonstration project to test techniques perfected in Alberta. About 60 Canadians are involved on the project, and headquarters are in Usinsk, ca 100 km south of the oil fields. In the first half of 1992, oil production in the first phase of the venture averaged around 10,000 bbl/d and continues to increase

    Keene, Daniel L; Humphreys, Peter

    2005-08-01

    To review the demographics and workload characteristics of pediatric neurology in Canada. A standardized survey questionnaire was mailed out to practicing pediatric neurologists in Canada in 2001. Variables examined were age, gender, hours on call, regular hours worked per week, type of practice and projected changes in practice over next five to ten years. Results were compared to the 1994 Pediatric Neurology Manpower Survey which had used the same survey instrument. Fifty-six (70%) pediatric neurologists practicing in Canada returned the survey. As was the case in 1994, no significant differences in workload were found based on age or gender. The average age of the practicing pediatric neurologist in 2001 was 51 years compared to 45 years in 1994. The proportion of physicians over 55 years in 2001 was 35% compared to 25% in 1994. Pediatric neurology in Canada is an aging specialty needing a significant recruitment of new members

  17. Emerging Churches in Post-Christian Canada

    Directory of Open Access Journals (Sweden)

    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.

  19. Canada's nuclear non-proliferation policy

    International Nuclear Information System (INIS)

    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

  20. Raw materials for energy generation in Canada

    Energy Technology Data Exchange (ETDEWEB)

    Robertson, D S

    1976-03-01

    Canada is self-sufficient in energy. The energy demand in Canada up to the end of the century is predicted, and the present and future of the oil, gas, coal and uranium industries are considered. Since it is now Canadian policy to restrict export of energy sources, in the future Canada will probably make more domestic use of its coal reserves. An increase is forecast in the use of coal for electricity generation and as a feedstock for synthetic gas. A long lead time and large capital expenditure will be needed before coal can be transported from western Canada to markets in the east of the country. A relatively small amount of the coal reserves are extractable by surface mining, and new underground mining techniques will be needed to extract the extremely friable coal from the deformed seams in the mountains.

    A review of operations in 1998 and financial information from Gulf Canada Resources Limited is provided to keep shareholders abreast of company performance. Gulf Canada Resources Limited explores for, develops, produces and markets conventional and synthetic crude oil, natural gas and natural gas liquids. In 1998, the company's main operating centres were in western Canada (where it owns a nine per cent interest in the Syncrude Joint Venture), Indonesia, the North Sea and Australia. The report summarizes the company's energy resource activities, presents a detailed review of operations, and provides consolidated financial statements, and common share information. Although Gulf Canada Resources sold $ 1.2 billion worth of non-producing assets during the year, year end proved reserves of 838 million barrels of oil equivalent were less than ten per cent lower than a year earlier, reflecting reserve additions of 100 million barrels of oil equivalent. tabs., figs

  12. Croatian Language Maintenance in Canada

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Although the topic of language maintenance has received considerable attention from linguists around the world, there are still many aspects of this language-contact phenomenon that could be examined further. This paper aims to contribute to the existing body of knowledge by exploring the state of Croatian as a heritage language in Canada. The aim of the paper is two-fold. The first is to describe the demographic characteristics of the Croatian community by investigating the number of people of Croatian descent and the number of Croatian speakers in Canada. The second, and more specific, aim of the paper is to provide an account of the state of Croatian as a minority language and examine the extent of language maintenance in the community. To accomplish the first objective, Canadian census data (1996, 2001, 2006, and 2011 was analyzed, with special focus on linguistic census data (number and age of Croatian speakers in Canada, mother tongue of people of Croatian descent, language most used at home, etc.. To accomplish the second objective, census data was supplemented with data from a questionnaire-based survey completed by members of the Croatian community in Toronto. The survey was completed by 220 participants; 110 first-generation Croatian Canadians and 110 second-generation Croatian Canadians. Two versions of the questionnaire were designed, one for first-generation participants and the other for second-generation participants. The great majority of items in the two versions were identical; each version contained questions about demographic characteristics, language use in everyday life, and self-perceived language proficiency in English and Croatian. The majority of questions were of a closed type (multiple-choice questions and rating scales, but there were also some open-ended questions, so as to give participants the opportunity to express their viewpoint or comment on certain issues. Questions were written in both Croatian and English

  13. Radioactive waste management in Canada: progress and challenges 15 years after the policy framework

    from that development - the establishment of the Nuclear Waste Management Organization, the study of options for the long-term management of nuclear fuel waste, the Government's decision on the options, the agreement on a funding formula for nuclear fuel waste management, and the launch of the NWMO's siting process. In this same period, we also have witnessed progress on a long-term waste management facility for low and intermediate-level radioactive waste in Ontario - including an agreement with the hosting community. In addition, there has been further advancement in the management of uranium tailing, notably the launch of cleanup efforts at the Gunnar mine in northern Saskatchewan. Finally, the federal government has established robust programs for the management of historic and legacy wastes across the country. In terms of historic wastes, the Port Hope Area Initiative has advanced to the point where critical decisions will be made in 2011 on the launch of the implementation phase of that Project and the Low-Level Radioactive Waste Management Office continues to manage historic wastes at other sites across the country. As for legacy wastes, decisions are expected prior to the end of 2010 on the continuation of the Nuclear Legacy Liabilities Program which addresses decommissioning and radioactive waste liabilities at AECL sites in Manitoba, Ontario, Quebec, and Nova Scotia. The coming years will see the further advancement of these initiatives, all which will face their own challenges. Nevertheless, there is generally a defined strategy or path and the appropriate elements are in place to achieve success. Despite these initiatives, there remain gaps in Canada's approach to radioactive waste management. In particular, while there has been progress on the management of low and intermediate-level radioactive waste in Ontario to address wastes from Ontario Power Generation's facilities, there is, as yet, no long-term management approach defined for

  14. Reimagining Haj Khalil v. Canada

    Directory of Open Access Journals (Sweden)

    Reem Bahdi

    2009-02-01

    Full Text Available This paper emphasizes the importance of cultural competence for tort law by analyzing the Federal Court’s decision in Haj Khalil v. Canada. Given that this symposium in honour of Rose Voyvodic’s life and work is entitled “Re-Imagining Access to Justice,” this paper asks “how do the principles of cultural competence allow us to think about the facts of the Haj Khalil differently. In particular, what would a cause in fact analysis look like if it were informed by the principles of cultural competence?” My analysis proceeds by “reading the silences” or focusing on the unstated assumptions and unexplored elements of Haj Khalil’s story to bring into focus factors relevant to factual causation which remain largely unexplored or undervalued by the Federal Court. An examination of the facts that framed Haj Khalil`s claim against immigration officials through a culturally competent lens would open the possibility of a different understanding of causation as it arises on the facts of the case. While Canadian courts have emphasized the importance of social context for fair judgment, they have not fully come to grips with the implications of social context for judicial decision-making. This is particularly the case within negligence law which remains vexed by the need to maintain an objective standard while simultaneously recognizing the importance of context and circumstance to particular claims. Cet article souligne l’importance de la compétence culturelle pour le droit de la responsabilité civile délictuelle en analysant le jugement Haj Khalil c. Canada de la Cour Fédérale. Vu que ce symposium en honneur de la vie et de l’oeuvre de Rose Voyvodic est intitulé « Re-Imagining Access to Justice», cet article pose la question «comment les principes de compétence culturelle nous permettent-ils de concevoir différemment les faits de Haj Khalil. En particulier, comment se présenterait la causalité si l’analyse des faits

    2013-09-01

    The International Cancer Benchmarking Partnership (ICBP) was initiated by the Department of Health in England to study international variation in cancer survival, and to inform policy to improve cancer survival. It is a research collaboration between twelve jurisdictions in six countries: Australia (New South Wales, Victoria), Canada (Alberta, British Columbia, Manitoba, Ontario), Denmark, Norway, Sweden, and the United Kingdom (England, Northern Ireland, Wales). Leadership is provided by policymakers, with academics, clinicians and cancer registries forming an international network to conduct the research. The project currently has five modules examining: (1) cancer survival, (2) population awareness and beliefs about cancer, (3) attitudes, behaviours and systems in primary care, (4) delays in diagnosis and treatment, and their causes, and (5) treatment, co-morbidities and other factors. These modules employ a range of methodologies including epidemiological and statistical analyses, surveys and clinical record audit. The first publications have already been used to inform and develop cancer policies in participating countries, and a further series of publications is under way. The module design, governance structure, funding arrangements and management approach to the partnership provide a case study in conducting international comparisons of health systems that are both academically and clinically robust and of immediate relevance to policymakers.

  19. Canada's gas taxes = highway robbery

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2000-05-01

    This report was prepared for the second annual 'gas honesty day' (May 18, 2000) in an effort to draw attention to the frustration of Canadian taxpayers with gasoline retailers and the petroleum industry for the inordinately and unjustifiably high prices for gasoline at the pump. The report points out that the public outcry is, in fact, misdirected since the largest profiteers at the pumps, the federal government, remains largely unscathed. It is alleged in the report that gas taxes are tantamount to highway robbery. Ostensibly collected for road construction and maintenance, of the almost $ 5 billion collected in 1999, only a paltry $ 194 million was returned to the provinces for roadway and highway spending. The 10-year average of federal returns to the the provinces from tax on gasoline is a meager 4.7 per cent, which fell even further to 4.1 per cent in 1998-1999. Gasoline tax revenues continue to climb, while government commitment to real roadway and highway spending continues to decline. This document attempts to shed some light on the pricing structure for gasoline. Without defending or explaining the non-tax portion of the pump price charged by Canada's oil companies, which is a task for the oil companies to undertake, the document makes a concerted effort to raise public awareness and focus public attention on government's involvement, namely that gas taxes represent on average about 50 per cent of the pump price and that the majority of the taxes collected are not put back into road and highway improvements. The Canadian Taxpayers Federation, authors of this report, expect that by focusing debate on the issue of gasoline taxes a broad support for a lowering of the overall tax burden on motorists will result. Among other things, the CTF advocates reduction of federal and provincial fuel taxes to levels commensurate with highway funding; dedication of fuel tax revenues to highway construction and maintenance; elimination of the sales and goods

    2006-01-01

    To build a national Cuban capacity for training environmental health professionals directly linked to the needs of policy-makers and communities. The University of Manitoba and University of British Columbia collaborated with an established training centre in Cuba (the Instituto Nacional de Higiene y Epidemiologia--INHEM) and new centres in the Central (Santa Clara) and Eastern (Santiago) regions of the country. Cuba. In the mid-1990s, a comprehensive curriculum (masters and diploma programs) was collaboratively developed, applying interactive teaching methods, and was delivered through a series of workshops and other interactions in Cuba, and short-term visits to Canada by Cuban PhD students. The collaboration was successful in fulfilling capacity-building targets (over 50 Masters graduates, 467 Diploma graduates, over 30 trained core faculty in all regional centres as well as new curriculum and new accredited regional programs). Alongside this, a number of collaborative community-based research projects were undertaken in all three regions (drinking water in Santiago; housing and urban renewal, and dengue control in Havana; and tourism-related effects, and effective intersectoral management of population health determinants in Santa Clara). The collaboration led to adopting new strategies for challenges such as a dengue epidemic in 2002, and new research on the effectiveness of intersectoral management of risks of particular interest to both Cuban and Canadian policy-makers. It triggered an ambitious collaboration between the Canadian-Cuban team and colleagues in Ecuador in order to build a similar national network there, built on South-South and North-South links.
