    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.

    Diffusive gradients in thin films (DGT) devices were used to investigate the temporal and spatial changes in vanadium (V) speciation in the Churchill estuary system (Manitoba). Thirty-six DGT sets and 95 discrete water samples were collected at 8 river and 3 estuary sites during spring freshet and summer base flow. Dissolved V concentration in the Churchill River at summer base flow was approximately 5 times higher than those during the spring high flow (27.3 ± 18.9 nM vs 4.8 ± 3.5 nM). DGT-labile V showed an opposite trend with greater values found during the spring high flow (2.6 ± 1.8 nM vs 1.4 ± 0.3 nM). Parallel factor analysis (PARAFAC) conducted on 95 excitation-emission matrix spectra validated four humic-like (C1C4) and one protein-like (C5) fluorescent components. Significant positive relationship was found between protein-like DOM and DGT-labile V (r = 0.53, p V concentration in Churchill River. Sediment leachates were enriched in DGT-labile V and protein-like DOM, which can be readily released when river sediment began to thaw during spring freshet. PMID:27065459

    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.

  4. Identification of the vascular plants of Churchill, Manitoba, using a DNA barcode library

    2012-01-01

    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. Conclusions Our results provided fast and cost

    1994-01-01

    This is an X-band seasonal image of the Altona test site in Manitoba, Canada, about 80 kilometers (50 miles) south of Winnipeg. The image is centered at approximately 49 degrees north latitude and 97.5 degrees west longitude. This image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on April 11, 1994, during the first flight of the radar system, and on October 2, 1994, during the second flight of SIR-C/X-SAR. The image channels have the following color assignments: red represents data acquired on April 11, 1994; green represents data acquired on October 2, 1994; blue represents the ratio of the two data sets. The test site is located in the Red River Basin and is characterized by rich farmland where a variety of crops are grown, including wheat, barley, canola, corn, sunflowers and sugar beets. This SIR-C/X-SAR research site is applying radar remote sensing to study the characteristics of vegetation and soil moisture. The seasonal comparison between the April and October 1994 data show the dramatic differences between surface conditions on the two dates. At the time of the April acquisition, almost all agricultural fields were bare and soil moisture levels were high. In October, however, soils were drier and while most crops had been harvested, some standing vegetation was still present. The areas which are cyan in color are dark in April and bright in October. These represent fields of standing biomass (amount of vegetation in a specified area) and the differences in brightness within these cyan fields represent differences in vegetation type. The very bright fields in October represent standing broadleaf crops such as corn, which had not yet been harvested. Other standing vegetation which has less biomass, such as hay and grain fields, are less bright. The magenta indicates bare soil surfaces which were wetter (brighter) in April than in October.

    Surface electrical and electromagnetic geophysical methods can map enhanced electrical conductivity caused by acid mine drainage in mine tailings piles. In this case study, we investigate quantitative relationships between geophysical responses and the electrical conductivity, acidity and salinity of tailing samples at the Central Manitoba Mine tailings in Manitoba, Canada. Previous electromagnetic surveys at the site identified zones of enhanced conductivity that were hypothesized to be caused by acid mine drainage. In the present study, high-resolution EM31 and DC-resistivity measurements were made on a profile through a zone of enhanced conductivity and laboratory measurements of salinity and pH were made on saturation paste extracts from an array of tailing samples collected from the upper 2 m of tailings along the profile. Observed spatial correlation of pH and pore-fluid salinity in the tailings samples confirms that the enhanced conductivity in the Central Manitoba Mine tailings is due to acid mine drainage. Contoured cross-sections of the data indicate that the acid mine drainage is concentrated near the base of the oxidized zone in the thicker parts of the tailings pile. The zone of increased acidity extends to the surface on sloping margins causing an increase in apparent conductivity in shallow penetrating geophysical responses. The quantitative relationship between measured pH and salinity shows that the conductivity increase associated with the acid mine drainage is due only in part to conduction by ions produced from dissociation of sulfuric acid. Comparison of the observations with fluid conductivity estimates based on statistical relationships of pH and ion concentrations in water samples from across the tailings pile shows that Ca2 + and Mg2 + ions also make significant contributions to the conductivity at all values of pH and Cu2 +, Al3 + and Fe3 + ions make additional contributions at low pH. Variability in the measured conductivity at constant

  9. Preliminary Rock Physics Analysis on Lodgepole Formation in Manitoba, Canada

    2012-12-01

    We present rock physics analysis results of Lodgepole Formation, a carbonate reservoir in Daly Field, Manitoba, Canada. We confirmed that the Lodgepole Formation can be divided into six units in the study area: Basal Limestone, Cromer Shale, Cruickshank Crinoidal, Cruickshank Shale, Daly member and Flossie Lake member from the bottom, using eight well log data and previous works. We then performed rock physics analyses on four carbonate units (Basal Limestone, Cruickshank Crinoidal, Daly and Flossie Lake), such as Vp-porosity, AI-porosity, DEM (differential effective medium) modeling, and fluid substitution analysis. In Vp-porosity domain, the top unit, Flossie Lake member has lower porosity and higher velocity, while the other units show similar porosity and velocity. We think that this results from the diagenesis of Flossie Lake member since it bounds with unconformity. However, the four units show very similar trend in Vp-porosity domain, and we can report one Vp-porosity relation for all carbonate units of the Lodgepole formation. We also found that the acoustic impedance varies more than 10% from low porosity zone (3-6%) to high porosity zone (9-12%) from AI-porosity analysis. Thus one can delineate high porosity zone from seismic impedance data. DEM modeling showed that Flossie Lake would have relatively low aspect ratio of pores than the others, which implies that the top unit has been influenced by diagenesis. To determine fluid sensitivity of carbonate units, we conducted fluid substitution on four units from 100% water to 100% oil. The top unit, Flossie Lake, showed slight increase of Vp, which seems to be density effect. The others showed small decrease of Vp, but not significant. If we observe Vp/Vs rather than Vp, the sensitivity increases. However, fluid discrimination would be difficult because of high stiffness of rock frame. In summary, three lower carbonate units of Lodgepole Formation would be prospective and high porosity zone can be delineated

    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.

    Full Text Available Settlement in June 1992, of the Northern Flood Agreement between Manitoba, Canada, Manitoba Hydro and the Split Lake Cree First Nation resulted in the establishment of the Split Lake Resource Management Board (SLRMB which is comprised of community representatives and government appointees. The responsibilities of the SLRMB include: developing annual programs and budgets, conducting wildlife population and habitat assessments, developing land and resource plans, monitoring resource use, and reviewing land use and management proposals. The Board's mandate extends to management of all natural resources including several distinct caribou (Rangifer tarandus populations which frequent the Split Lake Resource Management Area (RMA. After one year of operation, the SLRMB has several accomplishments. Its success is attributable in part, to the Board's effective mix of Split Lake Cree First Nation and government of Manitoba appointees. A good communication strategy has also been crucial for increasing understanding about the board, delivering essential resource management messages, and soliciting input at the community level. Rapport, teamwork, credibility and a resulting "strong voice" have set the framework for the SLRMB to play a significant role in resource management in a large part of northern Manitoba.

  13. Canada's National Building Stone: Tyndall Stone from Manitoba

    Science.gov (United States)

    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

  15. Synthesis of borehole geophysical data at the Underground Research Laboratory, Manitoba, Canada

    International Nuclear Information System (INIS)

    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

    In this study, molecular weights of thiols from four laboratory cultures (Scenedesmus obliquus, Chlorella vulgaris, Euglena gracilis, and Attheya septentrionalis) and the Churchill River (Manitoba) were assessed using a fluorescent-labeling method such as monobromotrimethylammoniobimane (qBBr) and asymmetrical flow field-flow fractionation (AF4) coupled to a fluorescence detector. Concentrations of thiols in extracellular fractions ranged from 6.39 ± 3.39 to 39.2 ± 7.43 μmol g(-1), and intracellular concentrations ranged from 11.5 ± 4.52 to 41.0 ± 4.1 μmol g(-1). In addition, molecular weights (MW) of intracellular thiol ranged from 493 ± 24 to 946 ± 12 Da whereas extracellular thiol MWs varied from 443 ± 36 to 810 ± 174 Da. The novel method of combining AF4 to an on-line fluorometer and the incorporation of the thiol tag provided information regarding thiol concentration and composition of controlled and natural systems. Furthermore, the proposed methods allow for the simultaneous measurement of thiol and DOM MWs produced by microorganisms. By assessing characteristics of naturally produced thiols and lab-grown thiols, information regarding heavy metal complexation can be determined. PMID:25772566

  17. Acidity-salinity relationship in gold mine tailings in Nopiming Provincial Park, Manitoba, Canada

    International Nuclear Information System (INIS)

    Complete text of publication follows. Electromagnetic surveys were done at the Central Manitoba gold mine-tailings in Nopiming Provincial Park, Manitoba, Canada to map the thickness and electrical conductivity of the tailings and to define spatial variations in pore-water salinity. Modelling of data collected using EM38, EM21, and EM34 instruments indicates that the combined thickness of the tailings and underlying peat bog material decreases from 5 m on the north side of the tailings to less than 1 m on the south side. The EM31 survey results identify areas of enhanced conductivity on sloping surfaces on the south side of the tailings pile. These areas are spatially correlated with zones of increased tailings acidity defined by sparse in situ pH measurements. The observations support the hypothesis that acidification of the tailings is due to differential settling during the deposition of carbonate and sulfide in the tailings, with higher proportions of sulphide occurring closer to the discharge outlet on the south side of the pile. In order to examine the relationship between electrical conductivity (or pore water salinity) and acidity in more detail, dense sampling was conducted along a 50 m long by 1 m deep grid crossing a zone of enhanced conductivity. Laboratory measurements of electrical conductivity and pH were made on a total of 52 tailings samples. The results show that the enhanced salinity and pH occurs within the oxidized upper part of the tailings and that the acidic material is exposed on the sloping surfaces. Plots of conductivity versus pH for the data set define a function relating the two parameters that can be used, along with conductivity models, to establish the 3-D distribution of the acidity in the tailings pile.

  18. Iodine dispersion and effects on groundwater chemistry following a release to a peat bog, Manitoba, Canada

    International Nuclear Information System (INIS)

    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, Kd, for I in the bog was 1.361/kg, but it was strongly related to pore water concentration. Thus, a single Kd value was insufficient for describing the system. (author)

  19. Recently surveyed lakes in northern Manitoba and Saskatchewan, Canada: characteristics and critical loads of acidity

    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.

    This study explores the possible applications of a spring complex, East German Creek (EGC), Manitoba, Canada, as a terrestrial analogue for similar environments on Mars. Potential ancient spring deposits have been identified by Allen and Oehler (Allen, C.C., Oehler, D.Z. [2008]. Astrobiology 8, 1093-1112) in Vernal Crater, Arabia Terra, as well as in the intercrater plains of Terra Sirenum by Wray et al. (Wray et al. [2011]. J. Geophys. Res., 116, 1-41). EGC can provide guidance in the search for fossil spring deposits on Mars by using comparative mineralogy to contrast mineral identification from field studies to that available from remote sensing instruments such as the CRISM instrument aboard the Mars Reconnaissance Orbiter. The formation processes of EGC are also useful for finding spring-like environments on Mars. A variety of techniques were employed (X-ray diffractometry, reflectance spectra, water chemistry analysis) to analyze mineralogical changes in spring water precipitates with distance from the main springs at EGC, which were compared with concentrations of dissolved species in outflow water. Biosignatures in outflow stream sediments as well as the effect of surficial Fe oxyhydroxide coatings on the detection of underlying carbonate absorption features have also been spectrally characterized. Halite is the main mineral precipitated at EGC, followed by gypsum, and calcite. The presence of gypsum is readily detected in surficial precipitate spectra while halite does not have a diagnostic spectral signature in the 0.35-2.5 μm region. An absorption feature indicative of chlorophyll a is present in stream sediment spectra from most sampling stations and on outwash plain sediments. Carbonates appear to be spectrally detectable through a coating of ferric minerals, such as goethite by a characteristic absorption band near 2.3 μm. We attempted to detect significant spectral changes over an area of potential spring features in Vernal Crater on Mars using

  1. Origin of the Herman-Norcross-Tintah sequence of Lake Agassiz beaches in Manitoba, Canada

    McMillan, Kyle; Teller, James T.

    2012-05-01

    The giant glacial Lake Agassiz basin is fringed by many strandlines, which have long been used to trace the paleogeography of the former lake over its 5000 year history. The oldest and highest of these strandlines were placed into three groups by Warren Upham in the 1890 s - the Herman, Norcross, and Tintah - and form a staircase of small landforms. The formation of these old strandlines began as early as ~13.9 cal (12.0 14C) kyr BP and ended ~12.8 cal (10.8 14C) kyr BP, based on OSL dates and the history of lake level in the Agassiz basin. New mapping and augering of beach ridges in southern Manitoba, Canada, associated with the earliest phase of the lake, indicate that there are a series of up to 28 small discontinuous beach ridges that are generally only a few metres high and a few tens of metres wide. These beaches mainly consist of weakly defined beds of poorly sorted sediments; in many cases a central sandy diamicton unit lies stratigraphically between overlying beach sediments and clay diamicton (till) below. Spatially, ridges are separated by silty or sandy units or gravel lags; inter-beach lagoonal organics were not found. We discuss the possible origin of these Lake Agassiz beaches, concluding that they were deposited over a few centuries by episodic storm events, as lake level slowly declined. We base this conclusion on the nature of the sediments in the beach ridges and the regional geomorphology, as well theoretical considerations about sedimentation along a regressing shoreline of a large lake. Other origins are rejected, although some other factors may have contributed to formation of some of the beaches, such as temporary increases in sediment supply, variable rate of outlet erosion, and short increases in lake-level that reworked sediment upslope into ridges. Using the time frame of 13.9 to 12.8 cal kyr BP for the formation of the beaches, the average interval between formation of each beach is ~39 years.

  2. Hydrogeologic characteristics of domains of sparsely fractured rock in the granitic Lac Du Bonnet Batholith, southeastern Manitoba, Canada

    International Nuclear Information System (INIS)

    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

    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.

    Asthma has long been a major cause of illness and disability among young Canadians. From 1970-71 to 1987-88, hospital admissions for asthma increased significantly among Canadian children under the age of fourteen. Many hypotheses may explain this increase in asthma prevalence. There could be a true increase in the number of people developing symptoms of the disease or increased asthma rates could be an artifact due to changes in detection, diagnosis, treatment, or coding. This study reviews hypotheses put forward to explain the increase in asthma prevalence, and tests some of them in Manitoba for children aged 0-4. Physician claims data and hospital separation data were merged to create unique person oriented medical records. These records were used to estimate the number of children seeking medical services for asthma during a five-year period (1984-85 to 1988-89) and the change in rates over this time period. From 1984-85 to 1988-89, both prevalence and incidence rates for children less than five years of age increased. Prevalence rates showed strong seasonal peaks in the spring and the fall. There is no indication that asthma increased in severity. The hospitalization rate (the number visiting a hospital for asthma divided by the total number seeking medical care for asthma), the average number of hospital admissions per year, and the average number of days spent in a hospital per year did not increase. Levels of ozone (O3) and nitrogen dioxide (NO2) in downtown Winnipeg increased over the study period and asthma prevalence increased twice as fast in Winnipeg as in the rest of the province. For Manitoba, the increase in preschool-aged asthma does not appear to be due to increased use of medical services, a change in ICD coding, an increase in the severity of the cases, or a decrease in income levels. The increases appear to be at least partly due to changes in diagnostic practices. The relationship between asthma and air pollution needs more detailed study as

    Riverbank erosion on the Red River in Winnipeg, Manitoba has raised concerns over the last 20 years and more. Although several recent studies have shown that fluvial erosion can reduce riverbank stability and promote geotechnical slope failure, there are too few that have focused on this phenomenon. The present study includes field measurements, experimental testing, and numerical modelling to quantify fluvial erosion through a 10 km reach of the Red River. Results have shown that seasonal freeze-thaw processes can dramatically reduce the critical shear stress and increase erodibility of the riverbanks. Moreover, a simple method has been employed using hydrodynamic numerical models to define the applied shear stresses on the river banks based on the river water level, which will be useful for further research and design purposes. The TEMP/W numerical model was used to define seasonal frost depth to estimate freeze-thaw effects. Finally all field measurements, experimental and numerical models results were used to predict annual fluvial erosion through this reach of the river.

    There is increasing evidence that Mars may have once been a habitable environment. Gypsum is targeted in the search for Martian biosignatures because it can host extensive cryptoendolithic communities in extreme terrestrial environments and is widespread on Mars. In this study the viability of using different spectroscopy-based techniques to identify the presence of gypsum endolithic communities was investigated by analysing various cryptoendoliths collected from the Lake St. Martin impact crater (LSM), a Mars analogue site found in Manitoba, Canada. Concurrently, the cryptoendolithic microbial community structure present was also analysed to aid in assigning spectroscopic features to microbial community members. Two main morphologies of endolithic communities were collected from gypsum deposits at LSM: true cryptoendolithic communities and annular deposits on partially buried boulders and cobbles Endolithic communities were found to be visibly present only in gypsum with a high degree of translucency and could occur as deep as 3 cm below the exterior surface. The bacterial community was dominated by a phylum (Chloroflexi) that has not been previously observed in gypsum endoliths. The exterior surfaces of gypsum boulders and cobbles are devoid of spectroscopic features attributable to organic molecules and detectable by reflectance, Raman, or ultraviolet-induced fluorescence spectroscopies. However, exposed interior surfaces show unique endolithic signatures detectable by each spectroscopic technique. This indicates that cryptoendolithic communities can be detected via spectroscopy-based techniques, provided they are either partially or fully exposed and enough photon-target interactions occur to enable detection.

    Borehole sonic and density logs are essential for mineral exploration at depth, but its limited availability to link rock properties of different ore forming geologic structure is a hindrance to seismic data interpretations. In situ density and velocity logs provide first order control on the reflectivity of various lithologic units. We analyzed borehole logs from 12 drill holes over and around the Lalor VMS deposits geographically located in the northern Manitoba, Canada, in an attempt to characterize lithologic units based on its seismic properties. The Lalor Lake deposit is part of the Paleoproterozoic Flin Flon Belt, and associated with an extensive hydrothermal alteration system. Volcanogenic Massive Sulfide (VMS) zones are distributed in several ore lenses with relatively shallower facies comprise solid to solid sulfides, tend to be disseminated or Stringer sulfides, while deeper lenses are gold and silver enriched and occurred in the highly altered footwall region. Our analysis suggests that massive sulfide and diorite have higher acoustic impedance than other rock units, and can produce useful reflection signatures in seismic data. Bivariate distributions of P-wave velocity, density, acoustic impedance and Poisson's ratio in end-member mineral cones were used for qualitative assessment of the extent of alteration of various lithologic units. It can be inferred that hydrothermal alteration has considerably increased P-wave velocity and density of altered argillite and felsic volcanic rocks in comparison to their corresponding unaltered facies. Amphibole, garnet, kyanite, pyrite, sphalerite and staurolite are the dominant end-member alteration minerals affecting seismic rock properties at the VMS site.

    This dissertation describes the process of underdevelopment among the Cree Indian people of South Indian Lake, in Northern Manitoba, Canada, following the construction of the Churchill-Nelson River Hydro Project in 1975. The dissertation seeks to link the ecological, political, economic, socio-cultural and health aspects of the impact of the hydro project within the framework of the historical process of underdevelopment as it has occurred in Latin America, among Native people in the United States, and among Native people in Northern Canada. Utilizing both qualitative and quantitative data, a process of increased dependence is described as the product of two related processes. The first process is the impairment of the local commercial and domestic economy caused by the flooding of Southern Indian Lake, which has resulted in a decline in local productivity. The second process is the enhancement of consumerism through rising consumer expectations and a post-project increase in available goods and services which the people are increasingly unable to afford. The overall result has been a process of economic divergence at the local level. The dissertation concludes that the process of underdevelopment which has occurred in South Indian Lake has been the result primarily of changes in the local ecological system caused by the construction of the hydro project. These ecological changes have, in turn, resulted in secondary changes in the socio-economic system.

    2011-01-01

    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.

    We monitored lead exposure in Eastern Prairie Population Canada geese during summer-winter, 1986-1987 and 1987-1988 at 5 areas. Blood lead concentrations in geese trapped during summer at Cape Churchill Manitoba were below levels indicative of recent lead exposure (0.18 ppm). Geese exposed to lead (≥0.18 ppm blood lead) increased to 7.6% at Oak Hammock Wildlife Management Area (WMA), southern Manitoba, where lead shot was still in use, and to 10.0% at Roseau River WMA, northern Minnesota, when fall-staging geese were close to a source of lead shot in Manitoba. Proportion of birds exposed to lead dropped to National Wildlife Refuge in Missouri, 4.9% of all geese showed exposure to lead before the hunting season. Lead exposure rose to 10.0% after hunting ended and then decreased to 5.2% in late winter. Incidence of lead shot in gizzards and concentrations of lead in livers supported blood assay data. Soil samples indicated that lead shot continues to be available to geese at Swan Lake, even though the area was established as a non-toxic shot zone in 1978. Steel shot zones have reduced lead exposure in the Eastern Prairie Population, but lead shot persists in the environment and continues to account for lead exposure and mortality in Eastern Prairie Population Canada geese.

  16. Proposed amendment for Presidential Permit PP-63 and associated modifications to 500 kV international transmission line, Forbes, Minnesota to Manitoba, Canada Northern States Power Company. Final Environmental Assessment

    Energy Technology Data Exchange (ETDEWEB)

    1992-02-01

    Northern States Power Company, (NSP), a Minnesota investor owned utility has applied to the Office of Fossil Energy, United States Department of Energy, to amend Presidential Permit PP-63 to allow for alterations to the 500 kV transmission line and as sedated facilities currently regulated by this permit. The alterations proposed for the 500 kV line owned by NSP are part of a long term effort sponsored by NSP to upgrade the existing NSP transmission system to allow for increased exchange of electricity with the Manitoba Hydro-Electric Board. Presidential Permit PP-63 authorized NSP to construct, connect, operate and maintain a 500 kV line at the United States/Canadian border approximately seven-and-a-half miles west of Warroad in Roseau County, Minnesota. This line connects with a 500 kV line owned and operated by the Manitoba Hydro-Electric Board (MHEB), which extends from Dorsey, Manitoba, Canada to the United States/Canadian border. NSP proposes to increase the electricity transfer capability of this transmission facility by constructing a new 80-acre substation on the existing 500 kV line in Roseau County, Minnesota, and upgrading the existing substation at Forbes, Minnesota. The proposed Roseau substation would contain two 41.5 ohm series capacitor banks. In addition, static VAR compensators are to be installed at the existing Forbes Substation. Approximately 5 acres would be added to the 30-acre Forbes site to house the additional equipment. No new lines would enter or exit the facility. NSP proposes to place the new Roseau Substation in service in May 1993 and to complete the upgrading of the Forbes Substation in March 1994. The primary, initial purpose of these modifications is to enable NSP to import 400 megawatts of electric power from MHEB during the summer months to meet peak electrical demand in the Minneapolis-St. Paul area. It is expected that this power transfer would begin in 1993.

  17. Potential impacts of climate change on Manitoba Hydro

    International Nuclear Information System (INIS)

    An overview of Manitoba Hydro's system was presented during this PowerPoint presentation which focused on significant climate trends, the potential impacts of climate change and climate change initiatives at Manitoba Hydro compared to other utilities. Ninety-five per cent of the electricity generated in Manitoba comes from hydroelectricity from the Churchill/Nelson River drainage basin. Twelve existing generating stations in the province contribute to the total installed generating capacity of 5500 MW, of which 300 MW is exported to Saskatchewan, 200 MW to Ontario and 2000 MW to the United States. Significant climate trends indicate that temperatures are increasing and there is a greater incidence of extreme weather events which can affect water supply. Manitoba Hydro must plan future resource needs and estimate climate change impacts on future projects. The potential negative impacts of climate change include an impact on water supply as well as an impact on the balance of energy supply and demand. The potential positive impacts of climate change include increased river flows in some regions resulting in higher water supplies. This presentation also outlined emission management initiatives at Manitoba Hydro with reference to policy issues for Kyoto ratification, export rates with environmental premiums, domestic emission trading, and demand-side management. Targeted measures such as wind power, landfill gas and hydrogen were also outlined. 10 figs

    The hydrology of shallow lakes (and ponds) located in the western Hudson Bay Lowlands (HBL) is sensitive to climate warming and associated permafrost thaw. However, their biological characteristics are poorly known, which hampers effective aquatic ecosystem monitoring. Located in northern Manitoba along the southwestern coast of Hudson Bay, Wapusk National Park (WNP) encompasses numerous shallow lakes representative of the subarctic zone. We analyzed the distribution and diversity of diatom (microscopic algae; class Bacillariophyceae) assemblages in surficial sediments of 33 lakes located in three different ecozones spanning a vegetation gradient, from NE to SW: the Coastal Fen (CF), the Interior Peat Plateau (IPP), and the Boreal Spruce Forest (BSF). We found significant differences (P inventory of the diatom assemblages in the WNP region needed for monitoring programs to detect changes in shallow lake ecosystems and ecozonal shifts in response to climate variations.

    The benefits and disadvantages for Ontario in exporting hydro electricity from Manitoba were discussed. Manitoba Hydro is already a major exporter of electricity to the United States. A history of Manitoba-Ontario electricity transactions was provided. There are currently 5,000 MW of developable hydro in Manitoba. A map of potential transmission routes was presented and transmission costs were discussed along with reliability and security issues. Benefits of a large hydro purchase from Manitoba were considered to be: long term source of supply; predetermined prices; no air emissions; proven technology; a balanced portfolio; and, a high dispatch capability. In addition, the fact that hydro is a low impact, renewable energy source was considered to be beneficial. Case studies were provided with comparisons of other energy sources. Factors that should be considered in determining trade relations between the two provinces include long lived assets with a minimum 20 year contract; the potential to reduce emissions in Ontario; and, the fact that the regulatory process is long and uncertain. It was noted that it is currently easier to get approval for a coal-fired power plant than for low emission hydro. tabs., figs

    Soil carbon stocks represent long-term net accumulations of carbon that result from plant inputs, decomposition losses, combustion losses, and local gains and losses from lateral flow of dissolved and particulate carbon. We use several chronosequences (time since last fire) of various soil drainage types from Thompson, Manitoba and Delta Junction, Alaska to estimate decadal averages of inputs and losses to soil. Because northern soils are generally not well mixed, the shallow organic layers of these soils can be thought as discrete accumulations since the most recent fire overlies more decomposed layers that represent longer histories of disturbance and stabilization. Accumulation since the most recent fire provides an estimate of net primary production (NPP) inputs to soil and decomposition loss from these shallow layers. Accumulation of all organic layers provides an estimate of long-term inputs and decay. Shallow inputs (0.011 - 0.014 g/cm2; SE = 0.002 - 0.005) and turnover times for carbon decay (78 - 94 yrs) did not differ between sites. Long-term inputs also do not differ between the well- to moderately well-drained Alaska sites and the moderately well-drained Thompson site (0.013 g/cm2; SE = 0.005). However, our wettest chronosequence site, located in Thompson, did see higher rates of long-term inputs (0.031 g/cm2; SE = 0.009). Long-term turnover times (50 - 60 yrs) did not differ among sites.

    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.

    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

  10. A study of uranium series disequilibrium in core profiles and mineral separates from the samples of Lac du Bonnet granite from the URL site, Pinawa, Manitoba, Canada

    International Nuclear Information System (INIS)

    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.

    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 210Pb-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.

    Hudson Bay streamflow represents a major component of the streamflow in Canada, approximately 30% of all river discharge enters Hudson and James Bays. Three current hydrological research issues are examined for this region. First the relationship between streamflow and local climate change is reviewed. Second the impact of river discharge in James Bay is linked to sea level variations in Churchill, Manitoba and the implications of this on Hudson Bay recirculation are explored. Finally, the historical and projected sea level variations in the Bay are examined with particular emphasis on the Churchill, Manitoba record. The report is concluded by a discussion of future directions for hydrological research in the Hudson Bay region.%Hudson海湾的河川径流量在整个加拿大河川径流量中占有很大的比例,所有河流排泄量约30%流入了Hudson和James海湾.研究了该地区河川径流与当地气候变化之间的关系;把河川向James海湾的排泄与曼尼托巴省Churchill地区海水位的变化联系起来,讨论了其对Hudson海湾再循环的影响;根据曼尼托巴省Churchill地区海水位的观测资料重点讨论了该地区海水位在历史时期的变化及未来的预测变化等三个重要水文问题.最后指出了今后在Hudson海湾地区进行水文研究的方向.

  15. Should Manitoba join the nuclear club?

    International Nuclear Information System (INIS)

    Manitoba hosts the first nuclear community in Western Canada. AECL's Whiteshell Laboratories in Pinawa carried out research on reactor safety, waste management and a number of reactor types including small reactors for powering remote communities. The Whiteshell site is now being decommissioned but will likely remain under CNSC license for the next century. The site is ideal for a new power reactor with its location on a major river, a major transmission corridor that runs through the site, and its proximity to major markets. With the relatively small grid sizes in the Prairie Provinces, it makes sense for the provincial utilities to cooperate in the building of major projects so as not to overwhelm individual utilities with a large power rector. What is needed now is a formal feasibility study to address the economic factors in favour of a nuclear plant compared with the cost of remote hydro dams and expensive transmission costs. With nuclear expansion now envisioned both east and west of Manitoba it makes sense for the province to become involved. Because of its history and knowledgeable and supportive population Pinawa could readily host a nuclear power plant or any other nuclear operation. (author)

    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.

    Canada ranks ninth in the world in anthropogenic carbon dioxide emissions. Canada currently releases 1.9 percent of global carbon dioxide emissions from combustion of fossil fuels, production and treatment of oil and natural gas, and cement manufacturing. Canadian carbon dioxide emissions doubled between 1956 and 1986, growing at an average rate of about 2.4 percent per year. They reached a peak in 1979 and have since fluctuated within 10 percent of that amount. Despite the significant increase in emissions, Canada's share of global carbon dioxide emissions has declined slightly since 1956. On a per capita basis, Canada ranks fourth among nations in carbon dioxide emissions, with about 4.1 tons in 1986. This rate compares with the U.S. average of 5 tons per capita emissions have grown by about 25 percent since 1956. Canada, though a relatively small source of greenhouse gases, has been deeply involved in finding ways to reduce the risk of climatic change. The nation fortunately possesses opportunities to reduce this risk by saving energy, developing nonfossil energy resources, and facilitating international cooperation for capturing these opportunities worldwide

    International Nuclear Information System (INIS)

    This paper presented data on oil and gas activities in Manitoba during 2004, the busiest year in Manitoba's oil patch since the mid 1980s. Increases in the leasing of Crown and freehold acreage were also noted, with accompanying increases in drilling activity for the latter part of 2004. Details of Crown land sales were presented, with a total of 43,725 hectares of crown oil and gas rights under lease. During 2004, over 15,000 hectares of Crown oil and gas leases were sold, the highest figures since 1997. More wells were licensed and drilled in 2004 than in any year since 1986. Overall drilling success rate was 96.7 per cent. Details of top drillers in Manitoba were presented, with drilling activity focused in Waskada and Daly fields and the Sinclair area. Oil production increased by 0.7 per cent, with 1474 wells in production. Daily oil production statistics were presented, with the total value of Manitoba's oil production being $196 million. Details of the top 5 producers were provided, in addition to details of horizontal well production. Recent developments in Sinclair Field, Pierson L. Amaranth MC 3b A Pool, Waskada L. Amaranth I Pool and Virden Lodgepole D Pool were reviewed. The Manitoba Drilling Incentive Program was discussed with reference to the following enhancements: new well incentives, horizontal well incentives; holiday oil volume accounts; and marginal well major workover programs. Various Oil and Gas Act amendments were reviewed. In addition, the Williston Basin Architecture and Hydrocarbon Potential Project was discussed. 3 figs

    Nuclear research and development in Canada started in the 1940s as a responsibility of the federal government. An engineering design team was established at Chalk River, Ontario, to carry out research on heavy water moderated lattices. A zero-energy heavy water moderated research reactor, ZEEP, was built and achieved criticality in September 1945; it was in fact the first human-made operating reactor outside the USA. In 1947, the 20 MW heavy water moderated national research experimental reactor (NRX) started up. It served as one of the most valuable research reactors in the world, and provided the basis for Canada's development of the very successful CANDU series of pressurised heavy water reactors (PHWR) for power generation. Atomic Energy of Canada Limited (AECL) was established in 1952 as a federal Crown Corporation. It has both a public and a commercial mandate. AECL has overall responsibility for Canada's nuclear research and development programme (its public mandate) as well as for the Canadian reactor design (CANDU), engineering and marketing programme (its commercial mandate). Nuclear energy in Canada is a $5 billion per-year industry, representing about 150 firms, 21 000 direct jobs and 10 000 indirect jobs, and ∼$1.2 billion in exports - the value to the country's economy is much higher than the research and development funding provided by the federal government. The CANDU nuclear reactor system was developed by AECL in close collaboration with the Canadian nuclear industry, and in particular with Ontario Hydro (now Ontario Power Generation). Currently, Canada operates 17 CANDU reactors, which contribute 16% of the country's current electricity consumption. There are also 12 CANDU reactors operating abroad (in Argentina, China, India, the Republic of Korea, Pakistan and Romania). AECL is now developing the 'third generation plus' Advanced CANDU Reactor (ACR-1000), and also has the leading role internationally in developing the Generation IV

  3. Manitoba Hydro's earth power program and Manitoba market update

    International Nuclear Information System (INIS)

    An outline of Manitoba Hydro's Earth Power program was presented. Details of the heat pump market in Manitoba were provided, including details of residential and commercial sales. Total residential heat pump sales amounted to 577 units in 2004, equivalent to over $11.2 million in sales. Commercial installations amounted to approximately $12.7 million. An outline of industry players was presented. The goals of Manitoba Hydro were outlined in relation to geothermal energy and the Power Smart program. Their objectives included increasing awareness of geothermal energy, making heat pumps more accessible, and improving industry infrastructure. Other objectives included educating the public about life-cycle cost implications, residential loans and commercial incentives. To date, the residential power loan has provided financing to over 300 Manitoba home owners for installations, with electrical savings of over 1.34 Gwh and natural gas savings of 279,425 m3. The program is also committed to providing assistance with feasibility studies. Provincial tax credits for the Earth Program included a 10 per cent deduction of geothermal heat pump purchases from corporation income tax. Case studies of the program were presented along with an outline of the geothermal heat pump for homes booklet. Details of the residential earth power loan were provided, including details of installation, system completion and approval processes. Awards and accolades for the program include the 2004 HRAI Education supporter award and recognition by the David Suzuki Foundation, which highlighted the program as a national leader in encouraging and facilitating the use of GeoExchange technology. tabs, figs

    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.

    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

  7. Presentation to the Manitoba ethanol advisory panel

    International Nuclear Information System (INIS)

    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

    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.

  10. The impacts of climate change on agriculture in Manitoba

    International Nuclear Information System (INIS)

    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

  11. 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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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

    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.

  14. Supply from the west : opportunities from Manitoba

    International Nuclear Information System (INIS)

    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

    The paper described some of the main technical aspects of the commissioning of the Ponton static var compensator (SVC) to Manitoba Hydro's electrical system. Off-line simulations were performed to gain confidence in the system tests and to deliver a validated EMT-type model. The peak load of Manitoba Hydro is approximately 4200 MW with an installed generating capacity of 5700 MW. Approximately 70 per cent of the power is generated from 3 hydraulic stations on the Nelson River in northern Manitoba. This power is transmitted for 900 km via the Nelson River high voltage direct current (HVDC) transmission to the Dorsey switching station near the major load centre of Winnipeg. The AC system is interconnected with Saskatchewan to the west with four 230 kV AC lines, and with Ontario to the east by two 230 kV AC lines. There are three 230 kV and one 500 kV AC inter-ties between Manitoba Hydro and the power system in the United States. One 230 kV line travels south from the northern generators and inter-connects into the Ponton busbar where an SVC with a supplementary damping controller was recently installed to improve system stability. 7 figs.

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

    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 < 0.05); those under age 65 (p < 0.01 for each age subgroup); treaty Aboriginals (p < 0.001), and those living on reserve land (p < 0.001). 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.

    2012-03-01

    Full Text Available Manitoba Hydro is responsible for the continued supply of energy to meet the needs of the province and is committed to protecting the environment when planning the construction and operation of its facilities. Corporate policy dictates ongoing improvement of Environmental Management Systems (EMS in order to meet or surpass regulatory requirements. Environmental objectives are reviewed annually and programs are modified when necessary to address improvements in environmental performance. Manitoba Hydro plans and constructs major transmission projects throughout northern Manitoba which includes areas occupied by boreal woodland caribou. In recognition of the potential issues associated with hydro transmission construction in boreal caribou range, Manitoba Hydro hosted an expert workshop on May 8, 2007 to provide objective advice in the development of a draft corporate strategy that effectively directs targeted monitoring and research for environmental assessment and mitigation. The workshop focused on assessing the potential threats to boreal woodland caribou from a transmission line construction and operation perspective, and identifying appropriate approaches in site selection and environmental assessment (SSEA and long-term monitoring and research. A total of nine threat categories were reviewed to determine the degree and magnitude of potential effects that may result from transmission construction and operation; and of the original nine, five final threat categories were delineated. The main elements of the workshop provided strategic approaches for proactive pre-construction monitoring, research on recruitment and mortality for local populations impacted by ROWs and control areas, and various habitat monitoring, management, and mitigation techniques. Research and monitoring priorities have been identified and continued collaboration with Manitoba Conservation and other land users were also identified.

  4. The quest for a zero GHG emission province: can Manitoba offer Ontario energy lessons? Paper no. IGEC-1-032

    International Nuclear Information System (INIS)

    Canadian provinces have abundant energy resources, but historic energy development decisions have made Canada one of the highest per capita emitters of greenhouse gases in the world. New technologies and distributed network management have created opportunities for conservation and green energy supplies to reduce GHG emissions, but Canada's adoption rate lags behind several other countries. The promise of Ontario's new government to close its coal-fired power plants by 2007 and the aging of its nuclear power plants creates an immediate need for investments in approximately 20,000 MW of capacity over the next decade. Many advocates call for a shift from fossil and nuclear power to renewable energy. Ontario's neighbour, Manitoba, has embarked on a systematic energy plan to reduce fossil fuel use and increase renewables (including new energy efficiency standards, wind, hydro-electricity, biofuels, geothermal heat pumps and electricity exports) so that a net zero emission position can be reached. The paper reviews the green energy initiatives promoted in Manitoba and then considers these as options for Ontario. The conclusion is that Manitoba's plan of systematically linking its energy and economic development choices has created opportunities and lessons for other jurisdictions to also move toward a greener energy future.

    The newly built Manitoba Hydro Place in Winnipeg, Manitoba was designed to be a functional state-of-the-art energy efficient cost-effective building that is exemplary of the integrated design process (IDP) for achieving energy efficient, human-centred design. IDP was integral to balancing energy performance goals against objectives of signature architecture, urban revitalization and supportive workplace. The new head office building is a model for extreme climate responsive design, as Winnipeg is one of the coldest large cities in the world. Every aspect of the building is integrated to achieve 60 per cent or more in energy savings using passive energy sources while prioritizing occupant health and thermal comfort. The building incorporates 6-storey high winter gardens; a concrete structure designed to create a thermal mass and to provide a flexible column-free loft condition; a solar chimney that provides 100 per cent fresh air; a massive geothermal system that provides both heating and cooling; and a high performance building envelope. The construction was made possible with skilful management of a strong and integrated design and construction team. Decision-making was facilitated by open collaborative forums and workshops. 13 figs.

  6. Manitoba: path to a hydrogen future

    International Nuclear Information System (INIS)

    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)

  7. Comparison of the egg flotation and egg candling techniques for estimating incubation day of Canada Goose nests

    Reiter, M.E.; Andersen, D.E.

    2008-01-01

    Both egg flotation and egg candling have been used to estimate incubation day (often termed nest age) in nesting birds, but little is known about the relative accuracy of these two techniques. We used both egg flotation and egg candling to estimate incubation day for Canada Geese (Branta canadensis interior) nesting near Cape Churchill, Manitoba, from 2000 to 2007. We modeled variation in the difference between estimates of incubation day using each technique as a function of true incubation day, as well as, variation in error rates with each technique as a function of the true incubation day. We also evaluated the effect of error in the estimated incubation day on estimates of daily survival rate (DSR) and nest success using simulations. The mean difference between concurrent estimates of incubation day based on egg flotation minus egg candling at the same nest was 0.85 ?? 0.06 (SE) days. The positive difference in favor of egg flotation and the magnitude of the difference in estimates of incubation day did not vary as a function of true incubation day. Overall, both egg flotation and egg candling overestimated incubation day early in incubation and underestimated incubation day later in incubation. The average difference between true hatch date and estimated hatch date did not differ from zero (days) for egg flotation, but egg candling overestimated true hatch date by about 1 d (true - estimated; days). Our simulations suggested that error associated with estimating the incubation day of nests and subsequently exposure days using either egg candling or egg flotation would have minimal effects on estimates of DSR and nest success. Although egg flotation was slightly less biased, both methods provided comparable and accurate estimates of incubation day and subsequent estimates of hatch date and nest success throughout the entire incubation period. ?? 2008 Association of Field Ornithologists.

  9. PCB management at Manitoba Hydro's Waverley Service Centre

    International Nuclear Information System (INIS)

    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

    2003-07-01

    Three high voltage direct current (HVDC) converter stations are operated by Manitoba Hydro in conjunction with the northern generating stations on the Nelson River near Gillam, Manitoba. The Dorsey Converter Station, located approximately 900 kilometres (km) south of Gillam and 13 km northwest of Winnipeg, is an integral and critical component of Manitoba's HVDC system. The Dorsey Converter Station represents the southern terminus, where the power originating from Gillam is converted back to alternating current (AC) from DC for further distribution in southern Manitoba and for export. The current space cooling requirements for the converter station buildings are based on chiller systems scheduled to be replaced. There have been some success stories near Winnipeg with groundwater cooling, and field testing confirmed that the high permeability of the aquifer would be an asset for groundwater based cooling. The system which has been selected for installation, includes 5 pumping wells and 10 recharge wells to handle the total cooling load. Thermal interference between wells is expected to be such that winter thermal balancing would be required for sustainability, as demonstrated in digital simulations of aquifer heat transport. The assessment program and the major design considerations for this system were presented in this paper. 10 refs., 1 tab., 10 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

    Full Text Available Objectives: To analyze the prevalence of poor oral health and selected determinants in First Nations (FN and Caucasian samples in Manitoba, Canada. Study design: Cross-sectional survey, nested in a cohort study. Methods: FN and Caucasian participants completed a questionnaire on socio-demographic variables, oral health symptoms, and oral health-related behaviours as part of a broader cohort study comparing these ethnic groups for different chronic immune mediated diseases. Results: Caucasians reported higher levels of employment, education, and urban dwelling than FNs (p<0.001. FNs reported smoking more, and having poorer oral health-related behaviours than Caucasians (p<0.001. After adjustment for age and sex, FN reported having more oral health symptoms than Caucasians (odds ratio (OR: 2.71; 95% confidence interval (CI: 1.73, 4.52, but the association was reduced and not statistically significant after adjustment for other socio-demographic variables (OR=1.34; 95% CI: 0.58, 3.10. Oral health symptoms were associated with current smoking among FN (adjusted OR=2.67, 95% CI: 1.05, 6.78. Oral hygiene behaviours were significantly related to smoking status, rural living and education for both groups. Conclusions: Oral health-related behaviours and smoking were found to be significant factors explaining poor oral health, which were lower for the FNs cohort than the Caucasian sample. However oral health and related behaviours were less related to their ethnicity than to socio-demographic factors, suggesting that policies to change behaviour will not result in lasting reductions in oral health differences between these groups in Manitoba.

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

    Directory of Open Access Journals (Sweden)

    Yap Bie Yong

    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.

    Temitope Oriola

    2011-02-01

    Full Text Available Diasporic communities are everywhere conceivable in today’s globalizing world. Winnipeg, Manitoba, albeit rather slowly, has not been left out of the increasing diversity of the Canadian population sequel to the surge in flows of “Third World” bodies hitherto considered persona non grata in Canada. Dispensing with the concept “Black,” this paper investigates the assessment of the police and courts by a sample of Nigerians at a local church in Winnipeg. Participants in this study generally have a favorable view of the police and courts in Winnipeg. Consequently, one fundamental finding of the study is that totalizing, generalizing or homogenizing the experience of Blacks and/or Blackness is theoretically misleading. The paper argues that several studies that purport to investigate “Blacks” do not in anyway offer insights into the experiences and voices of newer immigrants or continental Africans.

  5. Revealing the hyperdiverse mite fauna of subarctic Canada through DNA barcoding.

    Directory of Open Access Journals (Sweden)

    Monica R Young

    Full Text Available Although mites are one of the most abundant and diverse groups of arthropods, they are rarely targeted for detailed biodiversity surveys due to taxonomic constraints. We address this gap through DNA barcoding, evaluating acarine diversity at Churchill, Manitoba, a site on the tundra-taiga transition. Barcode analysis of 6279 specimens revealed nearly 900 presumptive species of mites with high species turnover between substrates and between forested and non-forested sites. Accumulation curves have not reached an asymptote for any of the three mite orders investigated, and estimates suggest that more than 1200 species of Acari occur at this locality. The coupling of DNA barcode results with taxonomic assignments revealed that Trombidiformes compose 49% of the fauna, a larger fraction than expected based on prior studies. This investigation demonstrates the efficacy of DNA barcoding in facilitating biodiversity assessments of hyperdiverse taxa.

    2006-06-01

    Full Text Available Both Winston S. Churchill (1874-1965 and Franklin D. 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.

  7. Radioactivity levels in Winnipeg river fish at the Whiteshell Nuclear Research Establishment near Pinawa, Manitoba

    International Nuclear Information System (INIS)

    Routine monitoring of biologically important radioactivity levels in Winnipeg River fish started in 1963, two years before operation of the Hot Cell Facility and the WR-1 reactor commenced at the Whiteshell Nuclear Research Establishment (WNRE), near Pinawa, Manitoba, Canada. Fish were captured with commercial-size fishing nets set twice a year near the town of Pinawa (upstream of WNRE and the Seven Sisters Hydroelectric Generating Station) and 0.5 and 5 km downstream from WNRE. Radioactivity levels in fish taken downstream of WNRE showed a general increase in the late sixties, due to fallout from global nuclear weapons testing, and some increase in the late seventies, due to radio-nuclide releases from the Hot Cell Facility of WNRE. The average concentration of radioactive cesium in the flesh of fish caught downstream of WNRE varied between 0.003 and 0.027 Bq/g wet weight prior to 1971 and between 0.002 and 0.075 Bq/g wet weight in the period 1976 to 1978, depending on species. The radiological dose to a human (committed effective dose equivalent) from the consumption of 20 kg of downstream pickerel in 1978 was approximately 0.013 mSv due to 137Cs

    2003-07-01

    An in-service pipeline failure occurred on the TransCanada main line gas pipeline approximately 50 kilometres northeast of Brandon, Manitoba, on April 14, 2002. After a metallurgical analysis was performed, it was determined that the likely cause of the failure was stress corrosion cracking (SCC) of the near-neutral pH form, with the failure occurring on a 36-inch diameter high pressure natural gas pipeline. In addition, failures on the pipe and a failure location near the boundary between a till plain and a glaciodeltaic sand plain, seemed to indicate that the local environment influenced the failure mechanism. A study was initiated in June 2002 to help define the geoenvironmental conditions associated with the failure site and to investigate possible links between the failure mechanism and the site conditions. The study involved an airphoto and map study, a field study, and an assessment of geological and hydrogeological factors. The results of the study were presented and discussed. 7 refs., 1 tab., 10 figs.

    Oxidation reactions have depleted sulfide minerals in the shallow tailings and have generated sulfate- and metal-rich pore water throughout the East Tailings Management Area (ETMA) at Lynn Lake, Manitoba, Canada. Information concerning the tailings geochemistry and mineralogy suggest the sulfide oxidation processes have reached an advanced stage in the area proximal to the point of tailings discharge. In contrast, the distal tailings, or slimes area, have a higher moisture content close to the impoundment surface, thereby impeding the ingress of oxygen and limiting sulfide oxidation. Numerical modelling of sulfide oxidation indicates the maximum rate of release for sulfate, Fe, and Ni occurred shortly after tailings deposition ceased. Although the sulfide minerals have been depleted in the very shallow tailings, the modelling suggests that sulfide oxidation will continue for hundreds and possibly thousands of years. The combination of sulfide minerals, principally pyrrhotite, that is susceptible to weathering processes and the relatively dry, coarse-grained nature of the tailings have resulted in the formation of a massive-hardpan layer in the proximal area of the ETMA. Because extensive accumulations of secondary oxyhydroxides of ferric iron are already present, remediation strategies for the ETMA should focus on mitigating the release of sulfide oxidation products rather than on preventing further oxidation.

    Petrone, Richard M.; Rouse, Wayne R.

    2000-08-01

    An objective hybrid classification of daily surface weather maps for central and western Canadian sub-arctic locations was used to determine their dominant synoptic conditions during the snow free period. This classification yielded seven dominant synoptic types for each location during the snowmelt and snow-free periods (20 April-7 September), accounting for 90% of the days in period. The effects of source regions were used to explain the observed air mass characteristics, and their influence on the respective study locations. Cooler, drier air masses were the most frequent at both study locations. Arctic high pressure cells to the northeast brought the coolest air to the western sub-arctic site, Trail Valley Creek (TVC), Northwest Territories, while high pressure systems approaching from the northwest brought the coolest conditions to the central sub-arctic site, Churchill, Manitoba. Sub-tropical high pressure approaching from the west-southwest brought warm air to TVC, whereas stationary high pressure to the south warmed Churchill. These synoptic regimes exerted strong controls on the precipitation and evaporation components of the water balance as observed in terms of cloud cover, radiation and precipitation and evaporation efficiencies.

  18. The origins of a coming crisis : renewal of the Churchill Falls contract

    International Nuclear Information System (INIS)

    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

  20. Manitoba Hydro-Electric Board 52. annual report : Building as one

    International Nuclear Information System (INIS)

    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

  2. A revised conceptual hydrogeologic model of a crystalline rock environment, Whiteshell research area, southeastern Manitoba, Canada

    International Nuclear Information System (INIS)

    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

    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.

  8. The effect of the 'no net loss' of habitat guiding principle on Manitoba Hydro's Conawapa project

    International Nuclear Information System (INIS)

    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

  11. Petroleum investment opportunities in Manitoba - a geological, engineering and economic perspective

    International Nuclear Information System (INIS)

    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

  12. Petroleum investment opportunities in Manitoba: A geological, engineering and economic perspective

    International Nuclear Information System (INIS)

    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 m3 and remaining proved reserves are ca 6 million m3. 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

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

    International Nuclear Information System (INIS)

    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

This pattern is changing with increased life expectancy, a growing population, and a poor social environment that influences risk behaviors, metabolic conditions, and disparities in screening uptake. These factors alone do not fully explain differences in cancer risk between populations, as genetic susceptibility and environmental factors also have significant influence.

  17. 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

  18. Long-Term Hydrologic Monitoring Program. Project Shoal site, Sand Springs Range, Churchill County, Nevada

    International Nuclear Information System (INIS)

    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

  19. Environmental impact of flooding in the main reservoir of the Churchill Falls Power Plant, Labrador

    International Nuclear Information System (INIS)

    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

    A brief message from the Manitoba Premier provided the opening note in this document. He talks about plans for the expansion of ethanol production and use in the province to help protect the environment and to enhance economic opportunities. Some ethanol facts are provided, such as the adoption of ethanol production helps reduce the emissions from vehicles. Most often blended with gasoline, ethanol is a high-octane, water-free alcohol produced from renewable sources and the resulting fuel is called gasohol. Co-products are also produced such as gluten, specialty flours and feed for livestock. It has the added advantage of providing value-added opportunities for farmers. The context in Manitoba was reviewed, and the gasohol incentives described. Currently, the government of Manitoba is considering mandating an ethanol-blended fuel for all gasoline sold in the province. The benefits from a 10 per cent ethanol blend in all gasoline are identified, and a case study concerning the experience of the Golden Triangle Energy Co-operative in Craig, Missouri is examined. The Minnesota experience is also reviewed. The advantages of ethanol production in Manitoba, and the challenges faced by the industry are mentioned. The last section of the document deals with the proposed principles for the development of an ethanol industry in Manitoba. The opinion of individuals will be sought in the coming months as a consultation process gets under way throughout the entire province. refs., 2 figs.

  3. Analysis of system drought for Manitoba Hydro using stochastic methods

    Science.gov (United States)

    Akintug, Bertug

    Stochastic time series models are commonly used in the analysis of large-scale water resources systems. In the stochastic approach, synthetic flow scenarios are generated and used for the analysis of complex events such as multi-year droughts. Conclusions drawn from such analyses are only plausible to the extent that the underlying time series model realistically represents the natural variability of flows. Traditionally, hydrologists have favoured autoregressive moving average (ARMA) models to describe annual flows. In this research project, a class of model called Markov-Switching (MS) model (also referred to as a Hidden Markov model) is presented as an alternative to conventional ARMA models. The basic assumption underlying this model is that a limited number of flow regimes exists and that each flow year can be classified as belonging to one of these regimes. The persistence of and switching between regimes is described by a Markov chain. Within each regime, it is assumed that annual flows follow a normal distribution with mean and variance that depend on the regime. The simplicity of this model makes it possible to derive a number of model characteristics analytically such as moments, autocorrelation, and crosscorrelation. Model estimation is possible with the maximum likelihood method implemented using the Expectation Maximization (EM) algorithm. The uncertainty in the model parameters can be assessed through Bayesian inference using Markov Chain Monte Carlo (MCMC) methods. A Markov-Switching disaggregation (MSD) model is also proposed in this research project to disaggregate higher-level flows generated using the MS model into lower-level flows. The MSD model preserves the additivity property because for a given year both the higher-level and lower-level variables are generated from normal distributions. The 2-state MS and MSD models are applied to Manitoba Hydro's system along with more conventional first order autoregressive and disaggregation models and

    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

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

    International Nuclear Information System (INIS)

    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 (r2 = 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 18O 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-HCO3-SO4 groundwaters, with little Cl, and less depleted 18O 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. Group II high-F- groundwaters are interpreted as modern recharge from within the impact structure, displacing Group I groundwaters. Thus

  7. A review of existing renewable energy facilities in Canada

    International Nuclear Information System (INIS)

    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

  9. Manitoba Motor Dealers Association pilot project : final report

    International Nuclear Information System (INIS)

    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

  19. Comparison of statistical downscaling methods for climate change assessment in Manitoba

    International Nuclear Information System (INIS)

    Downscaling of global climate model output is a necessary step in many climate change impact analyses. Manitoba Hydro has recently funded a project to investigate the merits of different downscaling methods for assessing the impact of climate change on river runoff in the Prairie region. The presentation will provide an overview of various statistical downscaling methods and highlight the strength and weaknesses of each method. The downscaling methods were evaluated based on a range of characteristics, including their theoretical foundation, their ability to reproduce observed climate, their ease of use, and availability of software. The downscaled climate data were used as input to the hydrologic model SLURP calibrated for several watersheds in northern Manitoba and in the Winnipeg River basin. The hydrologic model can be considered an integrator that smoothes out much of the day-to-day errors in the down-scaled climate data. The downscaling methods are also evaluated after post-processing through a hydrologic model. (author)

    2006-07-01

    The proven and probable reserves of Manitoba's most recent oil field, the Sinclair Field, are estimated at 3.8 million m{sup 3}. There are 9 designated oil pools within the Sinclair Field which produce from the Bakken and Three Forks Formations, with the most productive interval being the Qu'Appelle Group in the Three Forks Formation. In 2005, the Sinclair Field represented nearly 20 per cent of Manitoba's total oil production. This paper described the geological setting of southwestern Manitoba and the northeastern flank of the Williston Basin, with reference to the Paleozoic, Mesozoic and Cenozoic strata that form a basinward thickening, southwestern sloping wedge. An erosion unconformity that marked the end of the Devonian represents a period of uplift that continued until early Mississippian time and affected the deposition, reworking and erosion of the Three Forks Formation. During Three Forks time, there was a shift in the depositional environment that produced the carbonates and evaporites of the Devonian, to a more transitional clastics-dominated environment. The regional isopach of the Three Forks was reviewed along with its structural features and tectonic interpretation. The shaley, silty dolarites, interbedded with shale and brecciated rocks of the Three Forks Formation have been highly affected by weathering and subsequent diagenesis and block faulting. It was suggested that future potential for another Sinclair-type oil play may exist east of Range 24W1. 8 refs., 12 figs., 2 appendices.

    As part of a species recovery program, 129 Canada lynx (Lynx canadensis) originating from British Columbia, the Yukon, Manitoba, and Quebec, Canada, and Alaska, USA, were reintroduced to southwestern Colorado, USA, from 1999 to 2003. Of 52 lynx mortalities documented by October 2003, six lynx, including a female and her 5-mo-old kitten, had evidence of Yersinia pestis infection as determined by fluorescent antibody test and/or culture. Postmortem findings in these lynx were characterized by pneumonia, ranging from acute suppurative pneumonia, to multifocal necrotizing pneumonia, to fibrinous bronchopneumonia. Histopathologic examination of lung revealed multiple areas of inflammation and consolidation, areas of edema and hemorrhage, and bacteria surrounded by extensive inflammation. Spleens had severe lymphoid depletion and hypocellular red pulp. Lymphadenomegaly was observed in only one plague-affected lynx. We hypothesize that these Canada lynx were exposed to Y. pestis by infected prey, and these are the first reports of plague in this species. PMID:17092896

  7. Seismic anisotropy in granite at the Underground Research Laboratory, Manitoba

    International Nuclear Information System (INIS)

    The Shear-Wave Experiment at Atomic Energy of Canada Limited's Underground Research Laboratory was probably the first controlled-source shear-wave survey in a mine environment. Taking place in conjunction with the excavation of the Mine-by test tunnel at 420 m depth, the shear-wave experiment was designed to measure the in situ anisotropy of the rockmass and to use shear waves to observe excavation effects using the greatest variety of raypath directions of any in situ shear-wave survey to date. Inversion of the shear-wave polarizations shows that the anisotropy of the in situ rockmass is consistent with hexagonal symmetry with an approximate fabric orientation of strike 023degree and dip 35degree. The in situ anisotropy is probably due to microcracks with orientations governed by the in situ stress field and to mineral alignment within the weak gneissic layering. However, there is no unique interpretation as to the cause of the in situ anisotropy as the fabric orientation agrees approximately with both the orientation expected from extensive-dilatancy anisotropy and that of the gneissic layering. Eight raypaths with shear waves propagating wholly or almost wholly through granodiorite, rather than granite, do not show the expected shear-wave splitting and indicate a lower in situ anisotropy, which may be due to the finer grain size and/or the absence of gneissic layering within the granodiorite. These results suggest that shear waves may be used to determine crack and mineral orientations and for remote monitoring of a rockmass. This has potential applications in mining and waste monitoring

    Crustal magnetic anomaly data from the OGO 2, 4 and 6 (Pogo) satellites are compared with upward-continued aeromagnetic data between 50 deg -85 deg N latitude and 220 deg - 260 deg E longitude. Agreement is good both in anomaly location and in amplitude, giving confidence that it is possible to proceed with the derivation and interpretation of satellite anomaly maps in all parts of the globe. The data contain a magnetic high over the Alpha ridge suggesting continental composition and a magnetic low over the southern Canada basin and northern Canadian Arctic islands (Sverdrup basin). The low in the Sverdrup basin corresponds to a region of high heat flow, suggesting a shallow Curie isotherm. A ridge of high field, with two distinct peaks in amplitude, is found over the northern portion of the platform deposits and a relative high is located in the central portion of the Churchill province. No features are present to indicate a magnetic boundary between Slave and Bear provinces, but a trend change is evident between Slave and Churchill provinces. South of 60 deg latitude a broad magnetic low is located over very thick (40-50 km) crust, interpreted to be a region of low magnetization.

    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.

  11. Post-excavation analysis of a revised hydraulic model of the Room 209 fracture, URL, Manitoba, Canada

    International Nuclear Information System (INIS)

    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)

  12. Actinide and rare earth element characteristics of deep fracture zones in the Lac du Bonnet granitic batholith, Manitoba, Canada

    International Nuclear Information System (INIS)

    The history of major, trace, and actinide element mobility and fluid infiltration has been studied in two deep fractures (>1 km) in the Lac du Bonnet batholith as part of the Canadian Nuclear Fuel Waste Management Program. Core samples collected from two fracture zones, FR1 and FR2 (∼1,175 m deep), containing saline groundwater (TDS = 50 g/L) were investigated mineralogically, chemically, and isotopically (238U-series, O and H). Several sequentially overprinting alteration states were identified from early high-temperature to later low-temperature hydrothermal alteration. K-feldspar, illite, chlorite, and later kaolinite formed during these stages. Subsequent infiltration of oxidizing fluids produced alteration of the chlorite to hydrous iron oxides. Fracture zone FR1 contains predominantly hematite coating; fracture zone FR2 is characterized by the formation of a breccia and by an intense alteration of the granite in contact with this breccia to illitic clay. Alteration occurred during infiltration either of formation brines or of isotopically evolved meteoric water where δ18O = 8 to 12 per-thousand and δD = -65 to -20 per-thousand, at calculated temperatures between ∼250 and ≤25 degrees C. Pronounced disequilibria of 234U/238U (230Th/234U (∼0.7), and 226Ra/230Th (∼0.9) exist in the illitic clay, indicating loss of 234U, 230Th, and 226Ra to the groundwater within the last 1.5 Ma. In contrast, an excess of 234U, 230Th, and 226Ra was measured in the brecciated samples. The disequilibria are consistent with a model involving loss of 234U, 230Th, and 226Ra to groundwater by α-recoil from U deposited on the illitic clay surfaces. These radionuclides were deposited subsequently in the nearby brecciated zone. 51 refs., 11 figs., 8 tabs

  13. Manitoba Hydro long-term high-voltage transmission line magnetic field monitoring project

    International Nuclear Information System (INIS)

    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

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

  16. Overview of the Government of Canada Nuclear Legacy Liabilities Program - 13551

    International Nuclear Information System (INIS)

    Nuclear legacy liabilities have resulted from more than 60 years of nuclear research and development carried out on behalf of Canada. The liabilities are located at Atomic Energy of Canada Limited's (AECL) Chalk River Laboratories in Ontario and Whiteshell Laboratories in Manitoba, as well as three shutdown prototype reactors in Ontario and Quebec that are being maintained in a safe storage state. Estimated at about $7.4 billion (current day dollars), these liabilities consist of disused nuclear facilities and associated infrastructure, a wide variety of buried and stored waste, and contaminated lands. In 2006, the Government of Canada adopted a long-term strategy to deal with the nuclear legacy liabilities and initiated a five-year, $520 million start-up phase, thereby creating the Nuclear Legacy Liabilities Program (NLLP). The Government of Canada renewed the NLLP in 2011 with a $439-million three-year second phase that ends March 31, 2014. The projects and activities carried out under the Program focus on infrastructure decommissioning, environmental restoration, improving the management of legacy radioactive waste, and advancing the long-term strategy. The NLLP is being implemented through a Memorandum of Understanding between Natural Resources Canada (NRCan) and AECL whereby NRCan is responsible for policy direction and oversight, including control of funding, and AECL is responsible for implementing the program of work and holding and administering all licences, facilities and lands.

  18. Analysis of borehole-radar reflection logs from selected HC boreholes at the Project Shoal area, Churchill County, Nevada; TOPICAL

    International Nuclear Information System (INIS)

    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

  19. Precambrian metamorphic conditions and crustal evolution, northeastern Alberta, Canada

    International Nuclear Information System (INIS)

    A complex of Precambrian polymetamorphic gneisses and granitoids of the Churchill structural province, northeastern Alberta, Canada has been examined structurally, petrographically, chemically and geochronologically. An Archean basement gneiss complex is indicated by Rb-Sr dating of pegmatites which cut both gneisses and granitoids (2470 +- 26 Ma with an initial 87Sr/86Sr ratio of 0.7030 +- 0.0008). A high pressure granulite facies (M1) mineral assemblage and older structures (D1) are assigned to the Archean. A moderate-pressure granulite facies (Msub(2.1)), a low-pressure amphibolite facies (Msub(2.2)), a greenschist facies (Msub(2.3)), and younger structures (D2) are of Aphebian age. Formation of granitoids by anatexis of the pre-existing Archean basement complex during Msub(2.1) is indicated by their Aphebian ages (ca. 1900 Ma) and high initial 87Sr/86Sr ratios (0.7100 +-0.0018). The path of retrograde metamorphism is linked with relatively slow rates of uplift and cooling. Late Aphebian sediments attained low-grade greenschist facies metamorphism only and are younger than the other metamorphic rocks. The tectonic evolution of this Precambrian mobile belt during the Aphebian contrasts with the stable Archean cratonic block in the Slave province to the north. (Auth.)

  20. Listening to Their Voices: Women Prisoners and Access to Justice in Manitoba

    Directory of Open Access Journals (Sweden)

    Debra Parkes

    2016-01-01

    Full Text Available The existing research into effective accountability and oversight of Canadian prisons has considered the situation of federally sentenced prisoners (that is, those serving sentences of two years or more and has raised serious questions about their ability to access justice in the sense of having adequate and accessible means to ensure that their treatment and conditions of confinement are just and in compliance with the law. Relatively little is known about the state of oversight and legal review processes at the provincial level, where jail terms are short and prisoners’ rights litigation is rare. This paper attempts to begin filling that gap in knowledge by examining the situation faced by women imprisoned in provincial jails in Manitoba. The paper first surveys the existing international and domestic laws concerning prisoners rights and avenues for redress in Manitoba, before moving on to consider why and how those mechanisms are utilized or not, by listening to the voices of women who have been incarcerated recently at the Portage Correctional Centre. Finally, the paper considers what legislative or policy changes might be made to provide access to justice for provincial prisoners, drawing on recommendations and insights from the women themselves. La recherche qui existe au sujet de la responsabilisation et de la surveillance efficaces des prisons canadiennes a porté sur la situation de prisonniers condamnés sous le régime fédéral (c’est-àdire, ceux qui purgent des peines de deux ans ou plus et a soulevé des questions importantes quant à leur capacité d’accéder à la justice dans le sens de disposer de moyens adéquats et accessibles pour assurer que leur traitement et leurs conditions de détention sont équitables et conformes à la loi. On connaît relativement peu quant à l’état de surveillance et des processus de recours juridique au niveau provincial, où les périodes d’emprisonnement sont courtes et les litiges

    1996-01-01

    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.

  2. Estimating the state of stress from subhorizontal hydraulic fractures at the Underground Research Laboratory, Manitoba

    International Nuclear Information System (INIS)

    We conducted 9 complete hydraulic fracturing in situ stress measurements in vertical borehole HF1 at the 420 Level of AECL's Underground Research Laboratory (URL), near Pinawa, Manitoba. The tests did not result in vertical fractures. Thus, a generalized least-squares criterion was employed to compute the estimated principal horizontal in situ stresses. The large number of redundant test results enabled us to estimate the stress condition with confidence, even though the hydraulic fractures were only gently inclined. The estimated in situ stress regime within the range between 25 and 95 m below the 420 Level (445-515 m below the surface) is Sv 12-14 MPa; Sh = 36(±16) MPa; SH = 54(±13) MPa at 120o(±32o). The results are consistent with other independently conducted measurements at the URL. (Author)

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

    International Nuclear Information System (INIS)

    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

    Lung cancer is the leading cause of cancer death worldwide. Non-small-cell lung cancer (nsclc) is the most common form of lung cancer, with a median age at diagnosis of 70 years. These elderly patients are often underrepresented in the randomized clinical trials upon which chemotherapy plans are based. The objective of the present study was to determine the patterns of treatment and survival in elderly patients with advanced nsclc in Manitoba.

  7. Hydrogeochemistry, groundwater ages and sources of salts in a granitic batholith on the Canadian Shield, southeastern Manitoba

    International Nuclear Information System (INIS)

    The hydrogeochemistry of the Lac du Bonnet granitic batholith has been determined for the region of the Whiteshell Research Area (WRA) in southeastern Manitoba, Canada. This work forms part of the geosciences studies performed for the Canadian Nuclear Fuel Waste Management Program over the period 1980-1995 by Atomic Energy of Canada Limited (AECL). Knowledge of the variation of groundwater chemistry and its causes is useful in assessing the performance and safety of a nuclear fuel waste vault located at depths of up to 1000 m in a crystalline rock formation of the Canadian Shield. Groundwaters and matrix pore fluids have been obtained by standard sampling methods from shallow piezometers in clay-rich overburden, from packer-isolated borehole zones intersecting fractures or fault zones in the bedrock, and from boreholes in unfractured rock in AECL's Underground Research Laboratory (URL). Eighty-six individual fracture groundwaters have been sampled and analysed from permeable zones in 53 boreholes drilled to depths of up to 1000 m in the Lac du Bonnet batholith. In addition, 28 groundwaters from piezometers in a large wetland area near the URL have been sampled and analysed to determine the influence of clay-rich overburden on the bedrock hydrogeochemistry. Analyses have been made for major and minor ions, pH, Eh, trace metals, and stable and radioactive isotopes, to characterise these groundwaters and relate them to their hydrogeologic regimes. Shallow groundwaters in the fractured bedrock are generally dilute (TDS 3 waters and show little indication of mixing with Ca-Mg-HCO3-SO4 groundwater from overburden sediments. The near-modern levels of 3H and 14C, and a warm-climate 2H/18O signature in these groundwaters, indicates that the upper ∼200 m of fractured bedrock contains an active groundwater circulation system with a residence time of tens to hundreds of years. Deeper fracture groundwaters (200-400 m depth) in recharge areas, are more alkaline, Na-Ca-HCO3

    Stringer, P.W.; Stringer, M.H.L.

    1974-01-01

    Four zones based on cover and species diversity of epiphytic lichens and bryophytes are designated for urban and suburban Winnipeg, Manitoba. Epiphyte cover decreases markedly towards the city center, and there is a well-defined area almost totally devoid of epiphytes in the central built-up region. As known levels of sulphur dioxide are generally low in the city center, other pollutants, especially emissions from gasoline-powered vehicles, e.g., carbon monoxide, ethylene, may be chiefly operative in the maintenance of this depauperate zone, with aridity associated with the heat island perhaps also important. Sulphur dioxide from oil refineries and the main city power plant may be locally important over smaller areas. The most city-tolerant species in Winnipeg are Candelaria concolor, Physcia adscendens, Xanthoria fallax, Amblystegium juratzkanum, Leskea obscura/polycarpa, and Pylaisiella polyantha, with Lecania dimera, Lecanora impudens, Parmelia bolliana, and P. subargentifera among the least tolerant. Increase in soredia production, and decrease in apothecial production towards the city center were observed in Candelaria concolor, Physcia millegrana, P. orbicularis, and Xanthoria fallax, and Physcia aipolia, P. ciliata, P. stellaris, and Xanthoria polycarpa respectively.

  14. Isotopic methods in hydrogeology and their application to the Underground Research Laboratory, Manitoba

    International Nuclear Information System (INIS)

    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, 2H/18O, 14C, 34S) of groundwaters, but will determine values of more exotic and unusual ratios, such as 6Li/7Li, and B11/B10, 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 3He/4He, 36Cl/Cl and 129I/I, will be used to assess their potential for adding to the hydrogeochemical understanding of flow paths in crystalline rock.

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.

  16. Individual and population doses in Manitoba from chiropractic x-ray procedures

    International Nuclear Information System (INIS)

    Manitoba (population of 1.0 million) has 37 chiropractors who perform x-rays on behalf of 100 practising chiropractors. In 1987 these specialists performed approximately 33 300 spinal x-ray studies. Cervical spine examinations contribute the lowest patient dose (average HE of 26 μSv); thoracic and lumbar spine examinations show considerably higher patient dose (HE in the range 24-410 μSv) Average patient HE was determined to be 220 μSv. Lumbar spine examinations account for 45% of all chiropractic x-ray examinations (84% of the collective dose). Cervical spine examinations also account for 45% of chiropractic x-ray examinations, but contribute only 5% of the collective dose with thoracic spine examinations contributing the 11% balance of the collective dose. Patients undergoing chiropractic procedures involving exposure to x-rays account for about 3.6% of all diagnostic x-ray procedures. The per caput dose contribution from chiropractic practice was calculated to be 7.3 μSv (1.2% of total population dose from diagnostic procedures employing ionising radiation). (author)

  18. In situ bioremediation of a diesel fuel spill in northern Manitoba

    International Nuclear Information System (INIS)

    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

  19. Canada's nuclear export policy

    International Nuclear Information System (INIS)

    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. (O.T.)

He developed neutron scattering as a powerful and versatile tool for investigating materials at the level of molecules and nano structures. The neutron source for this work is Canada's NRU reactor located at the Chalk River Nuclear Laboratories of the Atomic Energy of Canada Limited. This neutron source is also used for the production of medical isotopes, testing of components for the nuclear power stations and neutron scattering experiments on materials

  3. Uranium in Canada

    International Nuclear Information System (INIS)

    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

    2003-01-01

    A 1989 all-party motion of parliament called for the elimination of child poverty in Canada by the year 2000. Despite a series of policy initiatives, recent reports suggest that the child poverty rate may now be comparable to that in 1989. The apparent persistence of child poverty in Canada might reflect socioeconomic developments, or something about the way that child poverty is measured. Using micro data covering the period 1986 to 2000 we find little support for these explanations.

    Air conditioning and industrial cooling in Winnipeg, Manitoba requires large volumes of groundwater, with the bulk of this water pumped from the Upper Carbonate Aquifer. Pumping takes place at the erosional surface of several dipping Paleozoic carbonate units beneath the city. To prevent excessive drawdown, wastewater from these processes is reinjected into the aquifer. Heat loading from the surface, combined with this practice, leads to the creation of areas of elevated temperature within the Upper Carbonate Aquifer. An industrial area located in eastern Winnipeg is the site of the largest of these anomalies, where the aquifer's permeability is enhanced by the presence of conduits and discrete fractures. The use of numerical modeling showed that the greatest temperature anomalies occur where there are very high permeabilities, especially in the form of conduits and discrete fractures. Groundwater velocities are increased by these factors, and could result in the creation of plumes of heated water. Plumes of heated water are less likely to occur where the aquifer is thicker and conduits are absent, due to advective heat transport becoming focused between the injection well and the production well in lower permeability situations. These areas also correspond to the areas of decreased transmissivity in several parts of the Upper Carbonate Aquifer, and may not be capable of producing the required volumes of groundwater for thermal applications. Taking into account these permeability features in planning and design of non-consumptive groundwater systems in the Upper Carbonate Aquifer helps to minimize both drawdown and changes in aquifer temperature. 8 refs., 2 figs.

    2016-01-01

    Abstract The identity of Celastrina species in eastern Canada is reviewed based on larval host plants, phenology, adult phenotypes, mtDNA barcodes and re-assessment of published data. The status of the Cherry Gall Azure (Celastrina serotina Pavulaan & Wright) as a distinct species in Canada is not supported by any dataset, and is removed from the Canadian fauna. Previous records of this taxon are re-identified as Celastrina lucia (Kirby) and Celastrina neglecta (Edwards). Evidence is presented that both Celastrina lucia and Celastrina neglecta have a second, summer-flying generation in parts of Canada. The summer generation of Celastrina lucia has previously been misidentified as Celastrina neglecta, which differs in phenology, adult phenotype and larval hosts from summer Celastrina lucia. DNA barcodes are highly conserved among at least three North American Celastrina species, and provide no taxonomic information. Celastrina neglecta has a Canadian distribution restricted to southern Ontario, Manitoba, Saskatchewan and easternmost Alberta. The discovery of museum specimens of Celastrina ladon (Cramer) from southernmost Ontario represents a new species for the Canadian butterfly fauna, which is in need of conservation status assessment.

    Extensional forces within the Antarctic Plate have produced the Transantarctic Mountains rift-flank uplift along the West Antarctic rift margin. Large-scale linear morphologic features within the mountains are controlled by bedrock structure and can be recognized and mapped from satellite imagery and digital elevation models (DEMs). This study employed the Antarctic Digital Database DEM to obtain slope steepness and aspect maps of the Transantarctic Mountains (TAM) between the Royal Society Range and the Churchill Mountains, allowing definition of the position and orientation of the morphological axis of the rift-flank. The TAM axis, interpreted as a fault-controlled escarpment formed by coast-parallel retreat, provides a marker for the orientation of the faulted boundary between the TAM and the rift system. Changes in position and orientation of the TAM axis suggests the rift flank is segmented into tectonic blocks bounded by relay ramps and transverse accommodation zones. The transverse boundaries coincide with major outlet glaciers, supporting interpretation of rift structures between them. The pronounced morphological change across Byrd Glacier points to control by structures inherited from the Ross orogen.

  10. Science evaluation of the environmental impact statement for the lower Churchill hydroelectric generation project to identify deficiencies with respect to fish and fish habitat

    International Nuclear Information System (INIS)

    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.

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

    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.

    Experiments were conducted to adapt the cloth Nzi trap to a format suitable for fixed applications in biting fly sampling or control. Catches of tabanids [Tabanus L., Chrysops (Meigen), and Hybomitra Enderlein], and stable flies [Stomoxys calcitrans (L.)] in painted plywood traps were compared with those in standard phthalogen blue cloth traps, and in similarly painted cloth traps. The Manitoba horse fly trap and the Tabanus nigrovittatus Macquart "greenhead" box trap were used as additional standards during one tabanid season. Shiny features of traps reduced catches, e.g., paint on cloth instead of wood, or use of aluminum screening instead of netting. Nevertheless, appropriately painted plywood Nzi traps caught as many biting flies as did standard cloth Nzi traps, if paint finishes were matte, and with the use of phthalogen blue colorants. Nzi traps collected about the same tabanid fauna as the Manitoba and T. nigrovittatus traps, but with improved catches of Chrysops and Tabanus. Recommendations are provided on appropriate color matching, and selection of readily-available materials for trap construction. PMID:17461091

    An egg count survey using environmental fecal samples obtained in spring or early summer was conducted to estimate the apparent prevalence of Toxocara vitulorum in unweaned bison calves and of other intestinal parasites in adult bison on 98 farms in Manitoba and Saskatchewan. Calf samples were pooled (maximum 5 samples per pool) by farm and positive pools were examined to determine individual T. vitulorum counts. Toxocara vitulorum eggs were found on 4 farms in Manitoba and none in Saskatchewan. Apparent herd-level prevalence estimates were 12% [95% confidence interval (95% CI): 3.4% to 28.2%] and 0% (95% CI: 0% to 5.7%) respectively. Samples from adult bison contained eggs/oocysts from trichostrongyle species, Eimeria sp., Monieza sp., Capillaria sp., Nematodirus sp. and Trichuris sp. in 100%, 95%, 72%, 13%, 13%, and 5% of herds, respectively. Strongyloides sp. were not found in any herd. Further studies are needed to assess parasite distribution patterns in bison and to evaluate the risk that T. vitulorum may pose to bison, cattle, and wildlife. PMID:25183895

  2. Uranium in Canada

    International Nuclear Information System (INIS)

    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

  5. Provincial/territorial public education and outreach hubs on climate change : evaluation of pilot phase : Manitoba public education and outreach hub : final report

    International Nuclear Information System (INIS)

    In January 2001, the Manitoba government established the pilot hub for climate change public education and outreach (PEO) in the province. The PEO is hosted by Manitoba Eco-Network, an affiliate of the Canadian Environmental Network located in Winnipeg. The aim of the PEO is to conduct public education as it relates to the environment. In addition, it aims to enhance communications between various member organizations. The main goal of the Manitoba Hub is to build awareness and empower citizens of Manitoba to act in reducing greenhouse gas emissions at the individual and community level. An evaluation of the pilot was performed, and the results published in this report. The pilot proved successful, according to stakeholder support for continuing this initiative further. Some of the recommendations to improve on the initiative included: (1) development of a new business plan for the next phase, (2) the Climate Change Connection (CCC) should continue to look for opportunities to expand beyond traditional climate change stake holders, (3) negotiations should continue between the Hub and the Province on its appropriate role with the new Climate Change/Greenhouse Gas Community Challenge, and (4) a greater role in capacity building with local groups and members, such as professional development and training opportunities; the provision of tools for others to perform outreach; and, assistance for groups with funding. The valuable lessons learned throughout the pilot phase were discussed in this document. 3 tabs

  6. Let justice flow : report of the interchurch inquiry into Northern Hydro Development

    International Nuclear Information System (INIS)

    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

  7. Nuclear insurance in Canada

    International Nuclear Information System (INIS)

    Many years ago, a group of insurance companies founded an organization offering nuclear insurance, called Nuclear Insurance Association of Canada. The passage of Order-in-Council P.C. 1960-555 gave Atomic Energy of Canada Ltd. the power to indemnify suppliers, contractors, etc. against liability claims. The situation has remained essentially unchanged. In 1970 Parliament passed the Nuclear Liability Act, but it has never been proclaimed. The act sets mandatory levels of nuclear insurance as high as $75 million for firms involved in nuclear activity. It is expected that agreement between the insurers and government will be reached later this year (1976), so that the act can be proclaimed. (N.D.H.)

  9. Canada's Global Partnership Program

    International Nuclear Information System (INIS)

    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)

  10. Canada's reactor exports

    International Nuclear Information System (INIS)

    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

    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.

    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.

  13. Draft guidelines for the preparation of an environmental impact statement for the proposed Manitoba Hydro North Central Transmission Line Project

    International Nuclear Information System (INIS)

    The North Central Transmission Line Project and related installations are being planned to connect northern Manitoba communities with the provincial power grid. The line is to be subjected to an environmental assessment and review process required for projects that have an environmental effect on an area of federal responsibility. Draft guidelines for the assessment/review are presented which have been recommended to a federal-provincial panel that will conduct the assessment. These guidelines specify the intent and the scope of the environmental assessment, and the requirements regarding information to be collected and what is to be assessed. These requirements are listed in the categories of project description, environmental setting, predevelopment planning review, impact assessment, mitigation, residual impacts, monitoring and research, public input, technical references, and report format

    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.

  15. Blasting in the lower shaft station of Atomic Energy of Canada Limited's Underground Research Laboratory

    International Nuclear Information System (INIS)

    Atomic Energy of Canada Limited (AECL) has the responsibility for research, and development of technologies, for the safe and permanent disposal of Canada's nuclear fuel wastes. As part of this comprehensive program, AECL is constructing an Underground Research Laboratory (URL) near Lac du Bonnet, Manitoba, to evaluate aspects of the concepts of waste disposal deep in stable geological formations. No nuclear wastes will be used in the URL program. The lower shaft station of the URL was excavated between 1984 December and 1985 February. Substantial effort went into producing good results from the blasting to minimize the blast damage to the rock surrounding the excavation. All headings of the lower shaft station were excavated by the pilot heading and slash method. The blasts for the pilot headings were designed using a combination of Swedish and Canadian blast design methods, with the detailed layout of the blast holes being finalized at the excavation face. By experimenting with the perimeter of the pilot headings, it was possible to finalize the perimeter blast design before starting on the final walls

    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 way state governments, worldwide, count or do not count Indigenous peoples has contributed to inconsistent reporting of Indigenous health statistics. To address unreliable reporting in Canada, we reviewed laws on Indian status and the development of a national Indian Registration System (IRS) to track Indian status and eligibility. With this information as a guide, we linked the IRS to the Manitoba provincial health registry systems and were able to identify individuals with Indian status for health reporting. To improve reporting, we identified individuals often missed in this type of linkage. For instance, we identified children and adult children who were eligible for Indian status but not yet registered. Equally as important, we identified individuals not eligible for Indian status but have Indian heritage and/or represent potential individual Indian status eligibility cases before the courts to right a historic form of identity sex discrimination that has made them invisible in Canadian society and health reporting. A familial kinship approach was used to identify Indian children and adult children typically missed when a strict legal entitlement criteria is used for data linkage. Our reflective socio-legal data linkage approach expanded the number of Indian peoples for health reporting purposes and demonstrated a feasible, inclusive way to report on the health of Indians in Canada.

  18. Development and Implementation of a Comprehensive Program to Deal with Canada's Nuclear Legacy Liabilities

    International Nuclear Information System (INIS)

    The Government of Canada nuclear legacy liabilities have resulted from 60 years of nuclear research and development (R and D) carried out on behalf of Canada by the National Research Council (1944 to 1952) and Atomic Energy of Canada Limited (AECL, 1952 to present). These liabilities are largely located at AECL research sites, and consist of shutdown research buildings (including several prototype and research reactors), a wide variety of buried and stored wastes, and contaminated lands. The shutdown buildings and contaminated lands need to be safely decommissioned to meet federal regulatory requirements, and long-term solutions need to be developed and implemented for management of the wastes. More than half of the liabilities are the result of Cold War activities during the 1940's, 50's and early 60's. The remaining liabilities stem from R and D for medical isotopes and nuclear reactor technology, as well as national science programs. About 70 percent of the liabilities are located at AECL's Chalk River Laboratories (CRL) in Ontario, and a further 20 percent are located at AECL's shutdown Whiteshell Laboratories in Manitoba. The remaining 10 percent relate largely to three shutdown prototype reactors in Ontario and Quebec, which were key to the developmental stage of Canada's CANDU reactor technology. The inventory of legacy waste includes spent fuel, high-level, intermediate-level and low-level solid and liquid radioactive waste, and wastes (largely contaminated soils) from site clean-up work across Canada. Most of the wastes are in raw, unconditioned form, and limited characterization information is available for the wastes generated in past decades. In many cases unique and potentially costly solutions will be required to recover, handle and process the wastes. In conclusion: the Government of Canada has initiated a program to deal with nuclear legacy liabilities dating back to the Cold War and the birth of nuclear technologies and medicine in Canada.

    Full Text Available The Canadian Phalacridae are briefly surveyed. Two species, Phalacrus politus Melsheimer and Olibrus vittatus LeConte, are newly recorded in Canada. As a result, eight phalacrids are now known to occur in Canada. Thirteen new provincial records are reported including one from Saskatchewan, two from Manitoba, two from New Brunswick, three from Nova Scotia, two from Prince Edward Island, and three from Newfoundland and Labrador. The four species and ten provincial records of Phalacridae reported from provinces in Atlantic Canada are the first records of this family in the region. Information on the bionomics of these species is briefly summarized. The species include Phalacrus penicillatus Say, Phalacrus politus Melsheimer (a smut-feeding species associated with corn, sorghum, and other grasses, Olibrus vittatus LeConte, Olibrus semistriatus LeConte (an abundant floricolous species found in the heads of several genera of Asteraceae, Acylomus pugetanus Casey (an ergot-feeding beetle associated with various grains and wild grasses, and Stilbus apicalis (Melsheimer (an apparently surface-feeding, mold-grazing, facultatively parthenogenic species. The discovery of P. politus on insular Newfoundland is particularly noteworthy and represents a range extension of about 1,260 km. The possible origins of this apparently isolated and disjunct population are discussed, focusing on the glacial history of the region.

  1. Canada's disposal concept

    International Nuclear Information System (INIS)

    A concept for the safe and permanent disposal of nuclear fuel wastes from Canada's CANDU reactors has been developed by Atomic Energy of Canada Ltd. (AECL). The waste would be placed in an engineered disposal vault 500 to 1000 m below the surface in plutonic rock of the Canadian Shield. The multiple barriers to retain the waste and retard the release of radioactivity would be the waste form, the containers, buffer and backfill, and the rock overlying the vault. Numerous research programmes have been carried out to develop the technology for the concept. These include work on materials corrosion and failure mechanisms to assess the performance of the used fuel containers. Predictive modelling has shown that more than 97% of ASTM Grade 2 titanium containers will retain their integrity, even under pessimistic assumptions, for 1200-6000 years after emplacement, and even longer times may be achieved with other grades of titanium or copper. Other research has been aimed at vault sealing, at site characterization for an underground research laboratory and at the development of a methodology for assessing radiological and environmental effects after closure of the facility. A review of the safety and environmental impacts of the concept is now being carried out by an independent panel appointed by the government. (2 figures, 3 references) (UK)

  2. Canada's Clean Air Act

    International Nuclear Information System (INIS)

    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

  3. Energy in Canada

    International Nuclear Information System (INIS)

    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)

  4. De-icing technologies: Introduction to Manitoba Hydro's use of ice melting and ice rolling technologies to remove ice from subtransmission and 115 kV transmission lines

    International Nuclear Information System (INIS)

    Manitoba Hydro's Ice Storm Management Program to reduce ice damage to overhead power lines in the voltage range of 8 kV to 115 kV is described. Overhead power lines are de-iced either by AC ice melting, which involves placing a three-phase short at a calculated point, or ice rolling, which is a process of mechanically stripping ice from conductors. Direct current heating and underground distribution systems are also accepted prevention measures. Advantages and disadvantages of each of these methods of de-icing are reviewed. Material for this paper has been extracted from a workshop manual prepared for the 1993 and 1998 Ice Storm Management workshops organized by Manitoba Hydro through the Canadian Electrical Association. 1 ref

  8. Western Canada uranium perspective

    International Nuclear Information System (INIS)

    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 U3O8 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.)

    This paper examines the distribution of gambling dollars in Nova Scotia, Saskatchewan and Canada and studies the impact of this spending on households. We focus first on how gambling expenditures are related to the level and source of household income as well as to other demographic characteristics such as age, education, household composition, geographical area, and sources of income. Next we analyze how gambling expenditures are distributed among those households that gamble. We show how expenditure patterns differ in the intensity of gambling as measured by the proportion of household income or total amount of dollars spent on gambling. Then we study the affects that gambling has on spending on household necessities, changes in net worth, retirement savings and household debt. Finally we determine whether gambling expenditures act as a substitute or a complement to other recreational spending on entertainment products and services. Throughout the paper we offer a comparative analysis of provincial and national data. PMID:15353922

    2014-01-01

    Full Text Available Lower levels of physical activity are associated with childhood obesity. School physical education (PE policies have been identified as critical to improve child and adolescent physical activity levels but there has been little evaluation of such policies. In the province of Manitoba, Canada, the government implemented a mandatory PE policy in secondary schools designed to increase the daily physical activity levels of adolescents. The objective of this study was to examine the longitudinal changes in and the factors associated with the physical activity trajectories of adolescents in Manitoba during their tenure as secondary school students in the context of this school PE policy. The results found, despite the PE policy, a grade-related decline in the physical activity trajectories of adolescents; however, the decline in physical activity was attenuated among adolescents with low and moderate baseline physical activity compared to adolescents with high baseline physical activity and among adolescents who attended schools in neighbourhoods of low compared to high socioeconomic status. There are several possible explanations for these findings, including the influence of the PE policy on the PA patterns of adolescent subpopulations that tend to be at higher risk for inactivity in both childhood and adult life.

    2013-01-01

    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. PMID:23628429

    Full Text Available It is generally surmised that community stressors have an incubating effect for a variety of diagnoses on maternal and child health. This is of public health significance, as children of mothers facing long-term distress were found to have a 60% higher risk for asthma diagnosis at age 7 in Manitoba, Canada. Our objective was to determine the association of community stressors with childhood asthma prevalence in Winnipeg, Canada from participants who completed the Study of Asthma, Genes and the Environment (SAGE survey administered in 2002–2003 to a birth cohort from 1995. Measures of community socioeconomic makeup and community disorder with rank ordinalized by quintile at the census tract level were obtained from the 1996 Canada Census. Crime data (annual incidence per 10,000 persons by neighbourhood profile for 2001 was provided by the Winnipeg Police Service. Dichotomous caregiver report of child asthma along with other indicators from the geocoded SAGE survey allowed linkage to 23 neighbourhood profiles.

    Since 1978 AECL has been investigating plutonic rocks of the Canadian Shield as a potential medium for the disposal of Canada`s nuclear fuel waste. During the last two years this study has been continued as part of Ontario Hydro`s used fuel disposal program. Methods have been developed for characterizing the geotechnical conditions at the regional scale of the Canadian Shield as well as for characterizing conditions at the site scale and the very near-field scale needed for locating and designing disposal vault rooms and waste emplacement areas. The Whiteshell Research Area (WRA) and the Underground Research Laboratory (URL) in southeastern Manitoba have been extensively used to develop and demonstrate the different scales of characterization methods. At the regional scale, airborne magnetic and electromagnetic surveys combined with LANDSAT 5 and surface gravity survey data have been helpful in identifying boundaries of the plutonic rocks , overburden thicknesses, major lineaments that might be geological structures, lithological contacts and depths of the batholiths. Surface geological mapping of exposed rock outcrops, combined with surface VLF/EM, radar and seismic reflection surveys were useful in identifying the orientation and depth continuity of low-dipping fracture zones beneath rock outcrops to a depth of 500 to 1000 m. The surface time-domain EM method has provided encouraging results for identifying the depth of highly saline pore waters. The regional site scale investigations at the WRA included the drilling of twenty deep boreholes (> 500 m) at seven separate study areas. Geological core logging combined with borehole geophysical logging, TV/ATV logging, flowmeter logging and full waveform sonic logging in these boreholes helped to confirm the location of hydro geologically important fractures, orient cores and infer the relative permeability of some fracture zones. Single-hole radar and crosshole seismic tomography surveys were useful to establish the

    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.

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

    Directory of Open Access Journals (Sweden)

    Juha M. Metsaranta

    2003-04-01

    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.

    A short bulletin from the National Fusion Program highlighting in this issue Canada-Europe Accords: 5 year R and D collaboration for the International Thermonuclear Experimental Reactor (ITER) AECL is designated to arrange and implement the Memorandum of Understanding (MOU) and the ITER Engineering Design Activities (EDA) while EUROTAM is responsible for operating Europe's Fusion R and D programs plus MOU and EDA. 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. Eastern Canada hydrocarbon development

    International Nuclear Information System (INIS)

    Current petroleum industry activities on Canada's east coast, and future potential were discussed. Offshore drilling activity is proceeding in the Jeanne d'Arc Basin, in addition to the Sable and Terra Nova Offshore Energy Projects. Future potential for Newfoundland and Nova Scotia has been estimated at 30 billion BOE and 13 billion BOE respectively. Natural gas potential off Labrador was estimated at 37 Tcf, offshore Newfoundland at 41 Tcf, and offshore Sable Island at 49 Tcf with varying amounts of oil associated with each field. Cumulative industry spending is expected to reach $ 10 billion by the year 2000, and could reach $20 billion by 2005. Prospects for Mobil Oil, number One in discoveries and industry influence, and number Two in acreage among the partners, were reviewed. Some details of the Sable Offshore Energy Project were outlined. The estimated cost of the project is $2 billion. It is expected to be on stream in late 1999 with a total of 27 wells (11 in phase 1). Reserves are estimated at 3.5 TCF or more. Hibernia was on stream in November 1997. Total recoverable reserves at Hibernia are estimated at 750 MMBls. Peak production of 180,000 b/d is expected by 2000-2001. Life expectancy of 20 years is predicted. The Terra Nova project, located 25 miles southeast of Hibernia, was also reviewed. It will be on stream in late 2000 with total reserves of 350-450 MMBls of oil, peak production at 115,000 to 135,000 b/d with a life expectancy of 15 years. 21 figs

  3. SCWR Concept in Canada

    International Nuclear Information System (INIS)

    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

  4. Investigation of climate change impacts on Prairie's petroleum industry in Canada

    International Nuclear Information System (INIS)

    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

  5. Monitoring hydrogeological conditions in fractured rock at the site of Canada's underground research laboratory

    International Nuclear Information System (INIS)

    Atomic Energy of Canada Limited is constructing an Underground Research Laboratory (URL) at a depth of 250 m in a plutonic rock body near Lac du Bonnet, Manitoba. The facility is being constructed to carry out a variety of in situ geotechnical experiments as part of the Canadian Nuclear Fuel Waste Management Program. A unique feature of the URL, in comparison to other similar facilities such as the Stripa Mine in Sweden, is that it is to be constructed below the groundwater table in a previously undisturbed plutonic rock body. One of the main research objectives of the project is to develop and validate comprehensive three-dimensional models of the hydrogeology of the rock mass encompassing the URL site. Measurements made in an array of boreholes extending to depths of 1000 m on the 4.8-km2 study area have established that the permeability distribution in three major extensive subhorizontal fracture zones controls the movement of groundwater within the rock mass. An automated, electronic, piezometric pressure-monitoring system has been designed to collect continuous measurements from 75 isolated hydrogeological monitoring positions within the rock mass. Piezometric data have been collected from this monitoring network to establish baseline conditions prior to any excavation into the rock mass. These data have also been used to determine the steady-state, three-dimensional, groundwater flow regimes that exist at the URL site under natural conditions

  6. The latitudinal inventory of sup(137)Cs in vegetation and topsoil in northern Canada, 1980

    International Nuclear Information System (INIS)

    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

    1998-11-01

    The National Energy Board examined an application by TransCanada PipeLines Limited for permission to construct facilities on its natural gas pipeline system in Saskatchewan, Manitoba and Ontario in order to meet projected aggregate requirements. The application, dated April 29, 1998, as amended for 1999, is for proposed facilities including 156.1 km of pipeline looping, four new 28.3 MW compressor units, an aftercooler at one compressor station, manifolds at another compressor station, and other compression related items. The estimated capital cost of the proposed facilities is $402.9 million. Most of the pipeline looping would be constructed in either the winter of 1998-1999 or the summer of 1999. The remainder of the facilities would be constructed in the summer of 1999. The expected in-service date of the proposed facilities is November 1, 1999. The Board completed an environmental screening report. It was determined that the proposed facilities would not likely cause significant adverse environmental effects. The Board also determined that the project was economically feasible and that the the proposed facilities are required by present and future public convenience and necessity. The Board expressed its approval of the application and its readiness to issue a certificate, subject to the approval of the Governor in Council. 5 tabs., 1 fig., 2 appendices.

    The Ciidae of New Brunswick, Canada are reviewed. Seventeen species are recorded for New Brunswick, including the following 10 species that are newly recorded for the province: Ceracis singularis (Dury), Ceracis thoracicornis (Ziegler), Cis angustus Hatch, Cis fuscipes Mellié, Cis horridulus Casey, Cis striatulus Mellié, Dolichocis laricinus (Mellié), Malacocis brevicollis (Casey), Orthocis punctatus (Mellié), and Plesiocis cribrum Casey. Additional locality data are provided for the following species previously known from the province: Cis americanus Mannerheim, Cis creberrimus Mellié, Cis levettei (Casey), Cis submicans Abeille de Perrin, Dolichocis manitoba Dury, Hadreule elongatula (Gyllenhal), and Octotemnus glabriculus (Gyllenhal). Seven synonyms are proposed here; Cis pistoria Casey with Cis submicans Abeille de Perrin; Cis fraternus Casey, Cis macilentus Casey and Cis striolatus Casey with Cis striatulus Mellié; Dolichocis indistinctus Hatch with Dolichocis laricinus (Mellié); and Octotemnus denudatus Casey and Octotemnus laevis Casey with Octotemnus glabriculus (Gyllenhal). Lindgren funnel traps provided the majority of specimens for 15 of the 17 species reported from New Brunswick and were the sole source of specimens for seven of the 10 species newly reported here, suggesting they are a very useful tool for sampling Ciidae in the forests of New Brunswick.

    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.

  10. Streamflow in the Winnipeg River basin, Canada: Trends, extremes and climate linkages

    St. George, Scott

    2007-01-01

    SummaryThis study uses a network of long-term discharge gauges to examine how river flow in the Winnipeg River basin, Canada has behaved during the last one hundred years. The Winnipeg River influences the production of over 4600 MW of hydroelectricity, and is the most important component of the hydrological system used to generate power in Manitoba. Extreme low annual flows are caused by severe reductions in runoff from spring snowmelt, and follow dry weather during the previous summer and autumn over much of the basin. These conditions are associated with enhanced meridional flow across western Canada, and geopotential height anomalies during the previous autumn and winter that are very similar to the positive phase of the Pacific/North American (PNA) pattern. The winter PNA index appears to be an important control on streamflow in the Winnipeg River at both interannual and decadal time-scales, but may be modulated by conditions in the North Atlantic sector. Mean annual flows have increased by 58% since 1924, primarily because of large increases in winter discharge. Because similar trends are observed for both regulated and unregulated rivers, these increases are not artefacts caused by direct anthropogenic interference in the hydrological system. Increasing summer and autumn precipitation is the most probable cause of the changes in streamflow. The observed trends toward higher flows, combined with recent model projections, suggest that the potential threats to water supply faced by the Canadian Prairie provinces over the next few decades will not include decreasing streamflow in the Winnipeg River basin.

  11. Western Canada Sedimentary Basin competitiveness

    International Nuclear Information System (INIS)

    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

    . The trends in IROWC-N in the Atlantic provinces were significantly worse than the national trend; for example, in Atlantic Canada, the aggregated IROWC-N index tripled from 27.8 in 1981 to 87.5 in 2006. Increases in fertilizer use (except in British Columbia), increases in livestock numbers in Manitoba and the Atlantic provinces, and an increase in legume crop acreage were the main factors that contributed to the increase in IROWC-N estimates. Climatic factors were also involved, as droughts reduced yields, N uptake and N leaching in many regions of Canada in 2001. PMID:19592153

  14. The chemical composition, antioxidant activity and α-glucosidase inhibitory activity of water-extractable polysaccharide conjugates from northern Manitoba lingonberry

    Directory of Open Access Journals (Sweden)

    Kelly A. Ross

    2015-12-01

    Full Text Available Lingonberry (Vaccinium vitis-idaea L. is a small northern fruit that has been harvested historically by native North Americans and Northern Europeans. These berries have been traditionally consumed as food and for medicinal use. Lingonberries are reported to be rich in vitamin C, benzoic acid, and anthocyanins, which have been implicated in health benefits associated with the consumption of lingonberries. We hypothesized that water-extractable polysaccharides, conjugated with proteins and/or phenolics may also serve as bioactive compounds with potential health benefits in northern Manitoba lingonberries. A hot water extraction was used to obtain water-extractable polysaccharides from lingonberries and the water-extractable polysaccharides were fractionated into water-eluted/neutral and NaCl-eluted/acidic fractions using chromatography. The water-extractable polysaccharides were evaluated for their chemical composition and structural features. The antioxidant activity (FRAP and ABTS assays and potential of the polysaccharides to serve as α-glucosidase inhibitors were determined. The chemical composition and structural features of the water-extractable polysaccharides were influenced by fraction. The water-extractable polysaccharides and fractions all possessed antioxidant activity, while only the water-extractable polysaccharide conjugates and NaCl-eluted/acidic fraction demonstrated appreciable α-glucosidase inhibition. This work provides novel information indicating that water-extractable polysaccharide conjugates isolated from northern Manitoba lingonberry demonstrate bioactivity.

  15. Canada's commitment to nuclear technology

    International Nuclear Information System (INIS)

    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)

  17. Canada-China power experience

    International Nuclear Information System (INIS)

    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

  19. Canada report on bioenergy 2008

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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

    While the overall climate for women physicists both in academia and industry has improved significantly over the past decade in Canada, it will be some time before women are well represented. Numbers of women in physics at all academic levels have increased, but are less than ideal at the full professor level. Organizations such as the Canadian Association of University Teachers and local initiatives are striving to minimize the socio-economic and professional gaps between women and men. The Canadian Association of Physicists, through its Committee to Encourage Women in Physics, and the Natural Sciences and Engineering Research Council are supportive and serve as catalysts, bringing together men and women to discuss and address issues concerning women in physics across Canada.

  7. Nuclear criticality safety in Canada

    International Nuclear Information System (INIS)

    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)

    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

    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.

    Canada is a federal country of 10 provinces and three territories. High level information on mental health conditions and service use has mostly been generated from administrative data collected by provinces and territories. These include four major types - hospital admissions and discharges, physician billings, ambulatory care services, and drug databases. At the national level, the Canadian Institute for Health Information brings together this information to produce indicators of outcome. Although these data provide information on patient and health system characteristics, they do not capture the full spectrum of formal and informal mental healthcare. These include changes in health status, functioning, community integration and quality of life. As a result, some jurisdictions have begun to implement more standardized measures of outcome such as the clinician-rated Health of the Nation Outcome Scales or the inpatient Resident Assessment Instrument - Mental Health. In this paper we provide an overview of mental-health-related data sources in Canada, highlight some of the more progressive practices beginning to emerge, and conclude with some thoughts about how the routine measurement and reporting of mental health outcomes in Canada might be advanced including efforts at engaging both clinicians and decision-makers.

  15. Overview of Canada's uranium industry

    International Nuclear Information System (INIS)

    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

  16. Education of pharmacists in Canada.

    In Canada, the education of pharmacists is built upon a foundation of strong, research-intensive publicly funded universities and a universal health-care system that balances government and private financing for prescription medications. The evolution of pharmacy education and practice in Canada has laid the foundation for a variety of emerging trends related to expanded roles for pharmacists, increasing interprofessional collaboration for patient-centered care, and emergence of pharmacy technicians as a soon-to-be regulated professional group in parts of the country. Current challenges include the need to better integrate internationally educated pharmacists within the domestic workforce and tools to ensure continuous professional development and maintenance of competency of practitioners. Academic pharmacy is currently debating how best to manage the need to enhance the pharmacy curriculum to meet current and future skills needs, and whether a doctor of pharmacy (PharmD) degree ought to become the standard entry-to-practice qualification for pharmacists in Canada.

    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.

    2009-05-01

    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

  19. Report on the workshop examining the potential effects of hydroelectric development on Beluga of the Nelson River Estuary, Winnipeg, Manitoba, November 6 and 7, 1990

    International Nuclear Information System (INIS)

    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

    Abstract Objective To determine the location of Canadian abortion services relative to where reproductive-age women reside, and the characteristics of abortion facilities and providers. Design An international survey was adapted for Canadian relevance. Public sources and professional networks were used to identify facilities. The bilingual survey was distributed by mail and e-mail from July to November 2013. Setting Canada. Participants A total of 94 abortion facilities were identified. Main outcome measures The number and location of services were compared with the distribution of reproductive-age women by location of residence. Results We identified 94 Canadian facilities providing abortion in 2012, with 48.9% in Quebec. The response rate was 83.0% (78 of 94). Facilities in every jurisdiction with services responded. In Quebec and British Columbia abortion services are nearly equally present in large urban centres and rural locations throughout the provinces; in other Canadian provinces services are chiefly located in large urban areas. No abortion services were identified in Prince Edward Island. Respondents reported provision of 75 650 abortions in 2012 (including 4.0% by medical abortion). Canadian facilities reported minimal or no harassment, in stark contrast to American facilities that responded to the same survey. Conclusion Access to abortion services varies by region across Canada. Services are not equitably distributed in relation to the regions where reproductive-age women reside. British Columbia and Quebec have demonstrated effective strategies to address disparities. Health policy and service improvements have the potential to address current abortion access inequity in Canada. These measures include improved access to mifepristone for medical abortion; provincial policies to support abortion services; routine abortion training within family medicine residency programs; and increasing the scope of practice for nurses and midwives to include abortion

  5. Landfill gas management in Canada

    International Nuclear Information System (INIS)

    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 (1015 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

  6. Nuclear waste management in Canada

    International Nuclear Information System (INIS)

    The classification of radioactive wastes in Canada involves two categories - waste of such a nature or in such amounts that it could be hazardous to the public, and waste which can be dealt with safely by methods available to individual institutions having at their disposal only conventional methods for getting rid of unwanted material. It is easy to provide for long-term retention of radioactive wastes if no account need be taken of expense. However, it is unreasonable (and discouraging to progress) to insist upon techniques of waste management that are applicable to multi-curie sources when the amounts to be dealt with are in the millicurie range.

  14. Natural background radiation in Canada

    International Nuclear Information System (INIS)

    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

  15. 2000 Western Canada activity forecast

    International Nuclear Information System (INIS)

    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

  16. 1999 Western Canada activity forecast

    International Nuclear Information System (INIS)

    The forecasts contained in this report are based on a review of the drilling activity through the first eight months of 1998 in twelve geographic areas of Western Canada. The forecasts incorporate current operator activity and trends into an estimate of well counts and meters drilled for the entire year of 1998. The estimates produced in this manner serve as the basis for the activity forecast for 1999. This projection, and cost data developed for the Association's 1998 Well Cost Study released in September 1998, provide the foundation for calculating the anticipated expenditure for various products and services in each of the specified geographical areas. Major operators in each area, and the type of drilling activities conducted by them, are also included. For Western Canada as a whole, a total of 9,885 wells are predicted to be drilled in 1999, at a total expenditure of $3.939 billion. The predicted average well depth will be 1,171 m, at an average cost of $ 219/m

  17. Nuclear emergency preparedness in Canada

    International Nuclear Information System (INIS)

    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.

  18. Eastern Canada natural gas developments

    International Nuclear Information System (INIS)

    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

  19. Energy in Canada: An overview

    International Nuclear Information System (INIS)

    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

  20. Canada's forest biomass resources: deriving estimates from Canada's forest inventory

    International Nuclear Information System (INIS)

    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

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

    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.

  7. 1999 Western Canada activity forecast

    International Nuclear Information System (INIS)

    Oil and gas drilling activity for the final quarter of 1998 and the first quarter of 1999 for 12 specific geographical areas in Western Canada is reviewed. Each area represents wells of common drilling, production and depth characteristics. Current operator activity and trends are incorporated into an estimate of well counts for 1999. Average drilling costs for each area are also calculated. Drilling of about 8920 wells is projected for 1999. The anticipated drilling and completion expenditures will be about $3.2 (Cdn) billion. While horizontal drilling activity appears to have decreased slightly in 1998, an increase to over 1200 horizontal and directionally drilled wells is projected for 1999. A list of the major operators in each geographical area is also provided. 8 tabs., 3 figs

  9. Environmental radioactivity in Canada 1988

    International Nuclear Information System (INIS)

    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.)

  10. Beyond design basis in Canada

    International Nuclear Information System (INIS)

    In response to the Fukushima Daiichi accident, the Canadian Government required: — Ongoing environmental monitoring on Canadian territory from coast to coast. — Deployment of experts to the IAEA. —Issuance of a directive pursuant to the regulatory requirements to all major nuclear facilities to review initial lessons learned. — Re-examination of the safety cases with a focus on: ● External hazards and measures to prevent or mitigate severe accidents; ● Emergency preparedness; ● Implementation of immediate short term and long term measures. At the regulatory level, the CNSC carried out reviews of the safety status of the plants in Canada and abroad. The CNSC site staff carried out focused inspection on seismic, fire, flooding, backup power, hydrogen igniters and passive recombiners, in addition to ongoing inspections against external hazards. The CNSC conducted inspections of spent fuel bays, their components and equipment, heat sinks and alarms, as well as the availability of on-site and off-site resources

  11. A search for high energy gamma rays from a quiet sun

    International Nuclear Information System (INIS)

    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-2s-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.)

    1996-01-01

    In the mid-1980s, the licensing authorities in Quebec, Ontario and Manitoba have introduced programs to conduct in-depth assessments of the clinical skills and abilities of physicians with suspected deficiencies. These assessments are intended to supplement the provincial licensing authorities' existing peer review or patient-complaint mechanisms by confirming the physicians' overall level of competence and identifying specific clinical strengths and weaknesses. An "educational prescription", based on the results of the assessment, focuses on aspects of clinical practice in which the physicians need or wish to enhance their skills. In some situations, licensure decisions are based on the assessment information. This article describes the programs in Quebec, Ontario and Manitoba. Each program comprises a different process of personal assessment and individualized continuing medical education to help physicians improve their clinical competence, and each is built on sound principles of clinical competence assessment and educational planning.

  13. Canada's nuclear non-proliferation policy

    International Nuclear Information System (INIS)

    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

  14. Uranium in Canada: Billion-dollar industry

    International Nuclear Information System (INIS)

    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

  15. Taxi and limousine industry in Canada

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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

    We report a 63-year-old lady with Cronkhite-Canada syndrome, who developed colorectal cancer. A hemicolectomy was performed, and the tumor specimen was prepared for DNA-analysis and immunohistochemical screening. We found a mutation of p53 gene without APC- and ras-gene alteration and expression of erbB2-protooncogen. The polyps in non-hereditary Cronkhite-Canada-syndrom are neither adenomatous nor hyperplastic, but patients often develop colorectal cancers. The steps of mutation do not follow the adenoma-carcinoma sequence, first described by Vogelstein 1988. This and previous observations suggest that carcinogenesis in Cronkhite-Canada syndrome follows another independent sequence. PMID:11413916

    2007-04-01

    Full Text Available This study examined the habitat characteristics of areas used by woodland caribou and areas disturbed by fire or logging in the Naosap caribou range in west-central Manitoba. The population inhabiting this area is currently considered to be of high conservation concern. The purpose was to determine how long after disturbance forests again resembled caribou habitat and whether there were differences in the recovery period between fire disturbed and logged areas. Sample transects were located in areas used by caribou and areas disturbed by fire or logging. Previously, it was shown that variables positively associated with habitat suitability in this region were species composition (presence of black spruce, an index of arboreal lichen abundance and tree size, while variables negatively associated with habitat suitability were deadfall abundance and species composition (presence of trembling aspen. It was hypothesized that if disturbed sites had become suitable caribou habitat, then they should be statistically indistinguishable from sites used by caribou based on these variables. Using cluster analysis, it was found that 2 statistical clusters showed the highest level of agreement with sampling clusters, with 88% of plots used by caribou classified into one cluster, and 74% of disturbed plots classified into the other. Although a small proportion (12% of disturbed plots resembled used plots, 30 years (the age of the oldest disturbed plot was not enough time, in general, for forest to return to conditions resembling caribou habitat in this region.

  5. Case studies: Experience in Canada [Factors affecting public and political acceptance for the implementation of geological disposal

    International Nuclear Information System (INIS)

    Canada has 22 nuclear reactors that, at this time, supply approximately 15% of the country's electricity. Canada's spent nuclear fuel is now stored on an interim basis at licensed facilities at the reactor sites located in Ontario, Quebec and New Brunswick and at the Atomic Energy of Canada Limited (AECL) facility in Manitoba. The issue of long-term management of spent fuel has been the subject of considerable study in Canada. At the request of the federal and Ontario governments, and after a 20-year research program, a concept for the management of spent fuel was developed by AECL. In its 1998 report, the environmental assessment panel provided insight and direction on key issues that had to be addressed in order to move the decision-making forward. The Government of Canada considered and responded to the panel report, and in November 2002 brought into force the Nuclear Fuel Waste Act (NFWA) which assigned roles and responsibilities and established the legislative framework for decision-making framework for the long-term management of its spent nuclear fuel. As required by that legislation, the Nuclear Waste Management Organization (NWMO) was established by the nuclear energy corporations. The NWMO was tasked with conducting a study of storage and disposal options, and will be responsible for implementing the management approach selected by government. After the Government selects the approach, implementation will unfold under the ongoing oversight of Natural Resources Canada. The Canadian Nuclear Safety Commission is responsible for the licensing and ensuring NWMO's compliance with regulatory requirements. The immediate task of the NWMO was to conduct a three year examination of different management options. The NWMO believed that an approach that generates confidence for the long term would need to resonate with citizen values and objectives for the study, and bring to bear the best science and technical understanding. A dynamic and iterative study was conducted

  14. 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.

  16. Canada's constitutional separation of (wind) power

    International Nuclear Information System (INIS)

    This paper investigates the impact that a federal government structure has on strategic selection of renewable energy policy instruments. The context for this study centers on wind power development in Canada. Canada is a nation that is blessed by all the attributes necessary to catalyze global leadership in installed wind power capacity. Unfortunately, the constitutional separation of powers that underpins Canada's federal system impedes the creation of a national wind power development strategy because Canada's provinces have constitutional authority over electricity governance. The insights gleaned from the case study are used to develop a conceptual framework for understanding the impact that federal structure has on policy instrument selection and efficacy under areas of federal, regional and concurrent policy jurisdiction. Finally, this framework is re-applied to identify specific approaches the Canadian federal government could take to resolve what currently amounts to be a fragmented, ineffective approach to wind power development planning.

The changes in the new version of the Plan are the result of continued consultations with industry and the provinces. The revised Plan addresses nine of the 12 concerns expressed by the provinces. Key changes include: (1) establishment of sectoral emissions reduction targets through negotiated covenants with a regulatory or financial backstop; (2) guaranteeing a limit of 55 Megatonnes reductions for covered sectors under the covenants and trading system; (3) introducing flexibility in timing by signaling willingness on the part of the Government to discuss acceptance of commitments over a longer term; (4) promising to work with industry on options for providing protection against risks associated with sustained carbon prices above certain levels; (5) designing implementation system in such a way as to not disadvantage those companies that have taken early action in emission reductions; (6) building in contingencies, assessing progress and adjusting the Federal approach and level of investment; (7) remaining engaged in joint efforts with the United States to minimize impacts on Canadian competitiveness. The Federal Government also recognizes the need for further research in addressing climate model uncertainties, in providing regional-scale climate change information, in future evolution of the climate in the Arctic, and in determining the record of past climate variability and extremes

  19. Gulf Canada's Russian joint venture

    International Nuclear Information System (INIS)

    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

  20. Understanding gasoline pricing in Canada

    International Nuclear Information System (INIS)

    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

  7. Increasing turbine vendor competition in Canada

    International Nuclear Information System (INIS)

    An overview of the wind turbine market in Canada was presented. Canada is now experiencing increased turbine vendor competition. Trends in wind turbine OEM market shares in Canada have increased from 10 per cent in 2000 to over 70 per cent in 2007. Several major companies in Canada have signed large-scale orders for delivery in 2010. It is expected that future wind turbine demands in all areas of Canada will increase. However, projections for Canadian wind growth demonstrate the difficulties provinces are now facing in trying to attract manufacturing investment away from the United States. Growth in wind turbine investment is in the process of creating a more robust North American wind turbine generator chain. However, the majority of new facilities are located in the United States. It is not known if Quebec's wind turbine generators will be viable outside of fulfilling Hydro-Quebec's tendering process. Canada's wind industry must consider equipment transport costs as well as a shortage of operating and maintenance service infrastructure. It was concluded that growth in the United States is expected to have a positive impact on Canadian wind energy customers. tabs., figs

  9. Opportunities in Canada's growing wind energy industry

    International Nuclear Information System (INIS)

    Investment in Canada's wind sector is projected to reach $8 billion by 2012, and growth of the sector is expected to create over 16,000 jobs. Canada's wind energy capacity grew by 54 per cent in 2005 alone, aided in part by supportive national policies and programs such as the Wind Power Production Incentive (WPPI); the Canadian Renewable Conservation Expense (CRCE) and Class 43.1 Capital Cost Allowance; and support for research and development. Major long-term commitments for clean power purchases, standard offer contracts and renewable portfolio standards in several provinces are encouraging further development of the wind energy sector. This paper argued that the development of a robust Canadian wind turbine manufacturing industry will enhance economic development, create opportunities for export; and mitigate the effects of international wind turbine supply shortages. However, it is not known whether Canadian wind turbine firms are positioned to capitalize on the sector's recent growth. While Canada imports nearly all its large wind turbine generators and components, the country has technology and manufacturing strengths in advanced power electronics and small wind systems, as well as in wind resource mapping. Wind-diesel and wind-hydrogen systems are being developed in Canada, and many of the hybrid systems will offer significant opportunities for remote communities and off-grid applications. Company partnerships for technology transfer, licensing and joint ventures will accelerate Canada's progress. A recent survey conducted by Industry Canada and the Canadian Wind Energy Association (CanWEA) indicated that the total impact of wind energy related expenditures on economic output is nearly $1.38 billion for the entire sector. Annual payroll for jobs in Canada was estimated at $50 million, and substantial employment growth in the next 5 years is expected. Canada offers a strong industrial supply base capable of manufacturing wind turbine generators and

  10. Canada vs. the OECD: an environmental comparison

    International Nuclear Information System (INIS)

    Canada's environmental performance is compared to the 28 other nations in the Organization for Economic Cooperation and Development (OECD). Twenty-five environmental indicators in ten categories are examined. These are: air, water, energy, biodiversity, waste, climate change, ozone depletion, agriculture, transportation and miscellaneous. Results show Canada with the poorest environmental record of all OECD countries, except the United States. The statistical information, compiled from data verified and published by the OECD, shows Canada among the worst three countries on nine indicators (per capita GHG emissions, CO and VOCs emissions, water consumption, energy consumption, energy efficiency, volume of timber logged, generation of nuclear waste, and the highest amount of energy consumed per unit of GDP). Tracking Canada's energy performance over the past two decades reveals that the situation is worsening in terms of water and energy consumption, production of nuclear and hazardous waste, greenhouse gas emissions, the number of endangered species, decline of fish populations, commercial fertilizer use, timber logging, number of motor vehicles, kilometres travelled by road, higher population and lower official development assistance (foreign aid). On the positive side, Canada's environmental performance was found to be poor but improving on ten indicators, including reduced air pollution, improved sewage treatment, reduced municipal waste, increased recycling, improved energy efficiency, decreased production of ozone-depleting substances and an increase in parks and protected areas

  11. Hot air : meeting Canada's climate change challenge

    International Nuclear Information System (INIS)

    As a large northern country, Canada will change significantly as a result of climate change. Global warming is expected to cause diminutions of snow and ice changes in the Arctic, as well as changes to glaciers, and the mountain snowpacks that feed rivers, and provide sources of fresh water. This book argued that the effects of global warming have been apparent in Canada for many years. Water levels in lakes and rivers have been falling, and a thawing permafrost has led to difficulties in building and maintaining winter roads in the far north. Disturbances such as the mountain pine beetle (MPB) infestation in British Columbia have also been attributed to global warming, the beetles are only killed by cold weather. The book also considered Canada's current climate change policies, and discussed attempts to arrive at meaningful and effective strategies. 30 refs

  12. Report on external occupational dosimetry in Canada

    International Nuclear Information System (INIS)

    In light of the new recommendations of the ICRP in Report 60 on dose quantities and dose limits, this working group was set up to examine the implications for external dosimetry in Canada. The operational quantities proposed by the ICRU are discussed in detail with regard to their applicability in Canada. The current occupational dosimetry services available in Canada are described as well as the several performance intercomparisons that have been carried out within the country as well as internationally. Recommendations are given with respect to standards for dosimetry, including accuracy and precision. More practical advice is given on the choice of dosimeter to use for external dosimetry, frequency of monitoring, and who should be monitored. Specific advice is given on the monitoring of pregnant workers and problem of non-uniform irradiation. Accident and emergency dosimetry are dealt with briefly. Suggestions are given regarding record keeping both for employers and for the national dose registry. 48 refs., 6 tabs., 1 fig

    2007-08-01

    Canada, like many countries, is in the midst of primary health care reform. A key priority is to improve access to primary health care, especially in remote communities and areas with physician shortages. As a result, there is an increased emphasis on the integration of primary health care nurse practitioners. As of March 2006, legislation exists in all provinces and two territories in Canada that allows nurse practitioners (NPs) to implement their expanded nursing role. In this paper, we will briefly review the historical development of the NP role in Canada and situate it in the international context; describe the NP role, supply of NPs in the country, and the settings in which they work; propose an NP practice model framework; summarize facilitators and barriers to NP role implementation in primary health care delivery; and outline strategies to address the barriers.

  14. Restructuring of Canada's nuclear utilities: recent developments

    International Nuclear Information System (INIS)

    Business decisions relating to the electric power sector are a provincial responsibility in Canada. The federal government looks to the three nuclear utilities to manage their nuclear assets and maintain them in a way that maximizes their reliability, efficiency and overall performance. A significant development in Canada's nuclear sector in the past year was the Ontario Hydro Nuclear Asset Optimization Plan. Structural change in the North American electricity market is a major impetus for decisions regarding nuclear assets by Canada's electric power utilities. The Ontario government is now taking steps to introduce competition in the Ontario Electricity market. The province of New Brunswick, which has one reactor at Point Lepreau which supplies one-third of the province's electricity, is also taking measures to introduce competition in its electricity market.

  15. The Hybridisation of Higher Education in Canada

    Directory of Open Access Journals (Sweden)

    Douglas Shale

    2002-01-01

    Full Text Available Canada's postsecondary institutions are becoming increasingly involved with technology enhanced learning, generally under the rubric of distance education. Growth and activity in distance education stems from rapid developments in communication and information technologies such as videoconferencing and the Internet. This case study focuses on the use of new technologies, primarily within the context of higher education institutions operating in Canada's English speaking provinces. Capitalising on the interactive capabilities of "new" learning technologies, some distance education providers are starting to behave more like conventional educational institutions in terms of forming study groups and student cohorts. Conversely, new telecommunications technologies are having a reverse impact on traditional classroom settings, and as a result conventional universities are beginning to establish administrative structures reflective of those used by distance education providers. When viewed in tandem, these trends reflect growing convergence between conventional and distance learning modes, leading to the hybridisation of higher education in Canada.

    Wild fires started by lightning are a significant source of carbonaceous aerosols and trace gases to the atmosphere. Careful observations of biomass burning plumes are required to quantify the long range transport and chemical evolution of the outflow from these fires. During the summer of 2011 an international effort - the Quantifying the impact of BOReal forest fires on Tropospheric oxidants over the Atlantic using Aircraft and Satellites (BORTAS) project - led by the University of Edinburgh, evaluated the chemistry and dynamics of Boreal biomass burning plumes through aircraft, satellite, and ground-based measurements. The Dalhousie Ground Station (DGS), located in Halifax, Nova Scotia, provided ground support to the BORTAS campaign. Two Fourier Transform Spectrometers (FTSs) provided solar absorption measurements of trace gases while two photometers provided aerosol optical depths. On 20 July 2011 a plume of elevated carbon monoxide and other trace gases was detected by the FTS instruments at the DGS; however, particulate data gathered from the co-located sun photometer and the Dalhousie Raman Lidar system showed no enhancement of fine-mode aerosol for the initial 7 hours of the event. After that time, particulates increased in abundance and a peak aerosol optical depth of 2.3 was measured on 21 July. FLEXPART trajectory analyses suggest that this plume originated in fires that were burning in Northwestern Ontario and Eastern Manitoba from 17 to 19 July. Despite the sparse observing network in the region, there is ample evidence of a significant lofting event via the same meso-scale convective system that tempered the burning on the 19th. We will provide an overview of this event and present evidence that precipitation scavenging was the most likely mechanism for the observed aerosol/trace gas anomaly. Support for this this research was provided by the Canadian Space Agency (CSA) and the Natural Sciences and Engineering Research Council of Canada.

  18. Action plan for electric mobility in Canada

    International Nuclear Information System (INIS)

    Electric mobility is an important emerging industry in Canada, where there is significant expertise in electric and hybrid vehicles, batteries, hybrid technologies, grid-connected technologies and fuel cell vehicles. This paper presented a case for the formation of Electric Mobility Canada, a proposed network of private companies and public sector agencies that aims to stimulate industry and provide support to government agencies involved with meeting Canada's obligations under the Kyoto Protocol, as well as in new industry sectors. The environmental, health, economic and industrial benefits of electric mobility were outlined. Current programs for electric mobility were reviewed, and details of financial incentives and initiatives were presented. An overview of electric mobility programs in the United States and Europe was provided. Research and development needs were evaluated. The former Electric Vehicle Association of Canada was discussed. An organizational structure for the proposed network was presented, along with a mission statement and outline of future goals. Recommendations for the future of the network included identifying short and long-term market opportunities for electric mobility technologies for all surface transport modes in Canada; determining research and development needs and appropriate funding and investment opportunities; determining other actions necessary to allow the electric mobility industry to play a growing role in meeting Canada's transport needs; and raising public awareness of the importance of electric mobility trends. It was concluded that the federal government should be approached for start-up funds for the network, which will be followed by further investment from provincial and business interests once the network is in place and functioning. 84 refs

  19. The nuclear ingredient in Canada's industrialization

    International Nuclear Information System (INIS)

    The energy scene in Canada has been confused by a changing industrial and economic pattern, a proliferation of energy options, a conflict of energy priorities, and possibly a media and anti-nuclear inspired perception that electricity is expensive and not a good substitute for oil. In spite of an economic down-turn, in 1982-83 five new CANDU reactors with a combined capacity of 3000 MW were completed in Canada. Opportunities exist for increased use of electricity both in households and in industry. The benefits of nuclear power have extended beyond a reliable and economic energy supply to research advances, job creation, and the overall industrial development of the country

    1991-11-01

    Ninety-four Canadian-born psychiatric patients who committed suicide were compared with 23 foreign-born patients committing suicide in Canada. East Europeans were over-represented, and significant differences were found in the age distribution, stress, level of education, social isolation, and methods of suicide. Most foreign-born patients had come to Canada for family or economic reasons but were unemployed, with poor social integration. Employment, housing, education, social integration and a support network seem to be important in preventing these deaths. Cultural evaluation of the patient and early intervention is recommended.

    Science.gov (United States)

    Goddard, W. R.; Boerner, W. M.

    1979-01-01

    The auroral-electrojet zone covers three quarters of Manitoba and consequently, solar storms strongly affect transmission lines. Harmonics are generated at transformers due to the saturation of their cores by induced currents, and the level of harmonics produced may cause malfunction of control relays, and yield unacceptable distortions in normal ac waveforms. The expected effects of long ac transmission systems were studied with emphasis on a 500 kv line to be built from Winnipeg to Minneapolis-St. Paul. Spectral analysis of induced current records from Manitoba Hydro's LaVerendrye station and magnetograms from IMS stations in Manitoba were used along with results of Campbell's work on the Alaskan pipeline induction problem (1978) in order to predict periodic and surge currents. It is concluded that the surge currents will produce significant levels of harmonics and corresponding operating problems during magnetic storms.

    2016-01-01

    Background: Previous studies have yielded inconsistent results for the effects of periconceptional multivitamins containing folic acid and of folic acid food fortification on congenital heart defects (CHDs). Methods: We carried out a population-based cohort study (N=5 901 701) of all live births and stillbirths (including late-pregnancy terminations) delivered at ≥20 weeks’ gestation in Canada (except Québec and Manitoba) from 1990 to 2011. CHD cases were diagnosed at birth and in infancy (n=72 591). We compared prevalence rates and temporal trends in CHD subtypes before and after 1998 (the year that fortification was mandated). An ecological study based on 22 calendar years, 14 geographic areas, and Poisson regression analysis was used to quantify the effect of folic acid food fortification on nonchromosomal CHD subtypes (n=66 980) after controlling for changes in maternal age, prepregnancy diabetes mellitus, preterm preeclampsia, multiple birth, and termination of pregnancy. Results: The overall birth prevalence rate of CHDs was 12.3 per 1000 total births. Rates of most CHD subtypes decreased between 1990 and 2011 except for atrial septal defects, which increased significantly. Folic acid food fortification was associated with lower rates of conotruncal defects (adjusted rate ratio [aRR], 0.73, 95% confidence interval [CI], 0.62–0.85), coarctation of the aorta (aRR, 0.77; 95% CI, 0.61–0.96), ventricular septal defects (aRR, 0.85; 95% CI, 0.75–0.96), and atrial septal defects (aRR, 0.82; 95% CI, 0.69–0.95) but not severe nonconotruncal heart defects (aRR, 0.81; 95% CI, 0.65–1.03) and other heart or circulatory system abnormalities (aRR, 0.98; 95% CI, 0.89–1.11). ConclusionS: The association between food fortification with folic acid and a reduction in the birth prevalence of specific CHDs provides modest evidence for additional benefit from this intervention.

  8. The disposal of Canada's nuclear fuel waste: postclosure assessment of a reference system

    International Nuclear Information System (INIS)

    The concept for disposal of Canada's nuclear fuel waste is based on a vault located deep in plutonic rock of the Canadian Shield. We document in this report a method to assess the long-term impacts of a disposal facility for nuclear fuel waste. The assessment integrates relevant information from engineering design studies, site investigations, laboratory studies, expert judgment and detailed mathematical analyses to evaluate system performance in terms of safety criteria, guidelines and standards. The method includes the use of quantitative tools such as the Systems Variability Analysis computer Code (SYVAC) to deal with parameter uncertainty and the use of reasoned arguments based on well-established scientific principles. We also document the utility of the method by describing its application to a hypothetical implementation of the concept called the reference disposal system. The reference disposal system generally conforms to the overall characteristics of the concept, except we have made some specific site and design choices so that the assessment would be more realistic. To make the reference system more representative of a real system, we have used the geological observations of the AECL's Whiteshell Research Area located near Lac du Bonnet, Manitoba, to define the characteristics of the geosphere and the groundwater flow system. This research area has been subject to more than a decade of geological and hydrological studies. The analysis of the reference disposal system provides estimates of radiological and chemical toxicity impacts on members of a critical group and estimates of possible impacts on the environment. The latter impacts include estimates of radiation dose to nonhuman organisms. Other quantitative analyses examine the use of derived constraints to improve the margin of safety, the effectiveness of engineered and natural barriers, and the sensitivity of the results to influential features, events, and processes of the reference disposal

  9. Characterizing fractured plutonic rocks of the Canadian shield for deep geological disposal of Canada's radioactive wastes

    International Nuclear Information System (INIS)

    Since 1978 AECL has been investigating plutonic rocks of the Canadian Shield as a potential medium for the disposal of Canada's nuclear fuel waste. During the last two years this study has been continued as part of Ontario Hydro's used fuel disposal program. Methods have been developed for characterizing the geotechnical conditions at the regional scale of the Canadian Shield as well as for characterizing conditions at the site scale and the very near-field scale needed for locating and designing disposal vault rooms and waste emplacement areas. The Whiteshell Research Area (WRA) and the Underground Research Laboratory (URL) in southeastern Manitoba have been extensively used to develop and demonstrate the different scales of characterization methods. At the regional scale, airborne magnetic and electromagnetic surveys combined with LANDSAT 5 and surface gravity survey data have been helpful in identifying boundaries of the plutonic rocks , overburden thicknesses, major lineaments that might be geological structures, lithological contacts and depths of the batholiths. Surface geological mapping of exposed rock outcrops, combined with surface VLF/EM, radar and seismic reflection surveys were useful in identifying the orientation and depth continuity of low-dipping fracture zones beneath rock outcrops to a depth of 500 to 1000 m. The surface time-domain EM method has provided encouraging results for identifying the depth of highly saline pore waters. The regional site scale investigations at the WRA included the drilling of twenty deep boreholes (> 500 m) at seven separate study areas. Geological core logging combined with borehole geophysical logging, TV/ATV logging, flowmeter logging and full waveform sonic logging in these boreholes helped to confirm the location of hydro geologically important fractures, orient cores and infer the relative permeability of some fracture zones. Single-hole radar and crosshole seismic tomography surveys were useful to establish the

  10. Canada and global warming: Meeting the challenge

    International Nuclear Information System (INIS)

    Canada accounts for ca 2% of total world emissions of greenhouse gases. Carbon dioxide emissions are by far the largest greenhouse gas source in Canada, primarily from energy consumption. On a per capita basis, Canada ranks second among industrialized countries in terms of energy related carbon dioxide emissions. Canada's northern geography and climate, its export-oriented economy with energy-intensive resource industries, and its relatively small population dispersed over a wide land mass contribute to this high per-capita value. The effects of global warming induced by greenhouse gases are outlined, including a reduction in water supplies, droughts affecting agriculture and forestry, and large-scale thawing of permafrost. A national strategy to respond to global warming has been developed which includes limiting and reducing greenhouse gas emissions, preparing for potential climatic changes, and improving scientific understanding and predictive capabilities with respect to climate change. Details of this strategy are outlined, including provincial and territorial strategies in partnership with the national strategy. 11 figs., 2 tabs

  13. Climate change effects on regions of Canada

    International Nuclear Information System (INIS)

    This report describes the major effects of climatic change being experienced in different parts of Canada, and emphasizes those that they are likely to become so severe that they may disrupt social, ecological and economic systems. The report notes that the driving force behind these impacts is change in temperature, precipitation, and in extreme weather events. The report strongly suggests that greenhouse gas emissions, particularly carbon dioxide, methane and nitrous oxide will likely continue to increase due to human activities such as burning of fossil fuels for heating, cooling and transportation. Loss of tropical forests is also listed as a cause for increased greenhouse gases. In order to reduce greenhouse gas emissions into the atmosphere, Canada must use energy much more efficiently, use more alternative renewable energy source and substitute natural gas for coal and oil whenever possible. It was emphasized that the ratification of the Kyoto Protocol would slow down the rate of increase of the world's greenhouse gas emissions, which in turn affect atmospheric concentrations. The author states that Canada's ratification of the Kyoto Protocol is key to global success, particularly since some countries have backed away from it and some are wavering. The report outlined the following major impacts of climate change in various parts of Canada: sea ice, permafrost, forest fires, transportation, toxic contaminants, storminess, precipitation, water supply, water quality, fisheries, hydropower, agriculture and human adaptation. refs., tabs

  18. Recent developments in Canada's climate change program

    International Nuclear Information System (INIS)

    This paper surveys Canada's official response to the responsibilities it took on with the Kyoto Protocol. In order to meet Kyoto targets for the timeframe 2008-2012, greenhouse gas emissions need to be reduced by 33 percent below what they currently are. Two billion Canadian dollars have been allocated to this effort. The government of Canada's official stance is that carbon dioxide levels have been rising more rapidly than at any other time in the last half million years. Canada's main efforts in the mining and minerals sector have been to find a replacement for sulphur hexafluoride, reduce emissions of perfluorocarbons, and demonstrate the use of hydrogen as a fuel for underground mining vehicles. According to the author, the most important contribution has been the use of supplementary cementing material such as fly ash, ash, and ground blast furnace slag.

  20. Petro-Canada annual report, 1991

    International Nuclear Information System (INIS)

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

Phenological observations were carried out on the plants growing on alluvial soil developed from light loam in Zakrz6w near Tarnobrzeg. It was proved that phenological development of Canada thistle, during broad-bean vegetation, depended on course of weather conditions and method of crop care. Emergence of the weed occurred earlier than broad-bean plants during warm and rather dry seasons. In every vegetation period, emergence and early vegetation stage (to 4 leaves seedling of Canada thistle lasted about 3 months, until broad-bean got full pod setting. During wet and cold season (in 2001 the weed emerged also early under herbicide (Afalon 1,5 kg ha-1 condition.

    International Nuclear Information System (INIS)

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

  15. Introducing small modular reactors into Canada

    International Nuclear Information System (INIS)

    In recent years there has been a growing interest in smaller, simpler reactors for generating electricity and process heat. This is evidenced in the growing body of literature and the increasingly frequent meetings and conferences on the subject. The interest in Small Modular Reactors (SMRs) is driven to a large extent by the desire to reduce capital costs, to reduce greenhouse gas emissions, to replace retiring fossil plants that do not meet today's environmental standards, and to provide power in locations away from large electrical grids. These drivers are as important in Canada as they are in the U.S., where the design and licensing of SMRs is being most vigorously pursued. They have led to a growing interest in Canada as a potentially significant market for SMRs, particularly in the Western Provinces of Alberta and Saskatchewan and in the remote First Nations communities of Northern Canada. There is a growing body of literature addressing the regulation and licensing of Small Modular Reactors in the U.S. Issues being identified in there can generally be categorized as licensing framework issues, licensing application issues, and design and manufacturing issues. Many of these issues are embedded in the US regulatory framework and can only be resolved through changes in the regulations. For the most part these issues are equally applicable in Canada and will need to be addressed in introducing SMRs here. A significant difference, however, is that these issues can be addressed within the Canadian regulatory framework without requiring changes in the regulations. The CNSC has taken a very proactive stance regarding the licensing of small reactors in Canada. They have published two new Regulatory Documents stipulating the requirements for licensing small reactors. A key feature is that they allow the application of a 'graded approach' in which the stringency of the design measures and analyses applied are commensurate with the level of risk posed by

  16. Greenhouse gas reduction and Canada's nuclear industry

    International Nuclear Information System (INIS)

    The Kyoto Protocol of the United Nations Framework Convention on Climate change, dated December 10, 1997 committed Canada to reduce greenhouse gases to 6% below 1990 levels by 2008-2012. Subsequently the federal government initiated a broad review of the implications of such a reduction across all sectors of the Canadian economy to identify options for eventual implementation. The Canadian nuclear industry participated in this review. This paper examines the status of this review to date and identifies options, which may significantly influence the use of nuclear energy domestically and internationally. This paper provides a review of options established by the three key Issue Tables in the context of implications to the nuclear industry. Several of the other Issue Tables have also identified options, which have major future implications for the use of nuclear energy. For example the Transportation Table has addressed the possible production and use of hydrogen fuel as an energy carrier. Biological and geological sinks are emerging technologies which will likely lead to increased energy demand. Development of the necessary infrastructure to support these new technologies could lead to a substantial need for increased production of electricity from greenhouse gas free sources in Canada in coming decades. In conclusion, international concern with climate changes re-focuses attention to human application of nature's energy sources. The studies implemented by the climate change secretariat have resulted in a comprehensive evaluation of opportunities for Canada to contribute to reduction of greenhouse gas emissions in Canada and abroad. The ability of Canada's nuclear industry to provide greenhouse gas free energy in the large quantities needed by modern society is recognized. (author)

    This article provides information on Alzheimer's disease and other dementias, using the 2010/2011 Canadian Community Health Survey, the 2011/2012 Survey of Neurological Conditions in Institutions in Canada, and the 2011 Survey on Living with Neurological Conditions in Canada. Among Canadians aged 45 or older, an estimated 0.8% in private households and 45% in long-term residential care facilities had a diagnosis of dementia. Prevalence rose with age. The vast majority of people with dementia in private households received assistance with medical care (81%), housework and home maintenance (83%), meal preparation (88%), emotional support (90%), transportation (92%), and managing care (92%). Among those receiving assistance, 85% relied, at least in part, on family, friends or neighbours. The primary caregiver tended to be a spouse (46%) or an adult child (44%), most of whom were daughters (71%). The majority of primary caregivers lived in the same household (83%) and provided daily care (86%). PMID:27192206

  19. Canada's climate change policy in context

    International Nuclear Information System (INIS)

    Climate change has a wide range of implications for the health, well-being, and economic prospects for Canadians, and for the ecological systems that sustain life on this planet. The overwhelming scientific opinion, world leaders and even a growing number of corporate leaders now agree that the Earth is undergoing a significant and unusual warming period as a result of the build-up of greenhouse gases in the atmosphere. There is also wide agreement that much of this build-up is anthropogenic, and that a global effort is required to slow this trend. Because climate change is a global problem, it requires global solutions by way of reduction in global greenhouse gas emissions. In this context, the Kyoto Agreement of 1997 constitutes a major breakthrough, even though it takes only a small step towards towards altering the human impact on global climate. Although some 80 states, plus the European Union signed the Kyoto Protocol, it remains unclear when it will come into force because the majority of states have failed to ratify it, pending the resolution of a variety of technical and operational details. Canada is the second highest emitter of greenhouse gases (16 tonnes per capita, compared to world average of 3.6 tonnes per capita). This, combined with Canada's foreign policy goals of playing a leading role in taking action and preserving its reputation as an honest broker, makes the challenge of meeting Canada's Kyoto commitments especially pressing. The purpose of this paper is to explain Canada's climate change policy in the context of these international and domestic pressures. The paper identifies the main climate change-related policy challenges, international responses to date and the constraints and opportunities open to Canada in the light of its economy, its federalist political structure, and place in the world as a middle power, as well as its geographic situation, natural resources and environmental endowment. There is a detailed discussion of the Kyoto

Information centers are part of all nuclear power plants and they receive many thousands of visitors each year. Until the 1970s public information programs were relatively easy. There was a lot of interest in nuclear energy, and there was little debate about it or opposition to it. But times have changed, and Canadian public information strategies and tactics have evolved to meet challenge of answering increasing public concerns. In the past 20 years Canada has gone through three phases in relationship with the public: information, communication, participation. Activities on implementation of these phases are outlined

    2009-01-01

    We performed a qualitative study of the practice of informed consent for videoconsultation in Canada. Fourteen cases were examined: the 13 provinces and territories, and the Federal jurisdiction representing aboriginal groups. Twenty-seven interviews were conducted with key informants (14 telehealth experts, 13 legal experts). The telehealth experts were people with direct experience of telehealth practice. The majority of the telehealth experts agreed that videoconsultations had not been integrated into the health-care system. An interesting finding of the study was that the integration status of videoconsultations was not indicative of informed consent practices. Telehealth providers favoured express written consent, or risk management practices, although there was a desire to move towards implied consent models for videoconsultations. The study also showed that the legal ramifications of the electronic transmission of non-recorded, real-time, personal health information had not been explored. This represents an important factor in guiding future consent for videoconsultations in Canada. PMID:19471027

    International Nuclear Information System (INIS)

    The carbon disclosure project conducts an annual survey to determine the strategies and actions of major cap companies in relation to climate change. This report discussed initiatives implemented by Canada's largest companies to prepare for a carbon-constrained future. The report documented results from 97 companies. The aim of the report was to help companies make use of the disclosures as reference points for future carbon markets and regulations relating to reporting requirements. Results of the survey demonstrated that Canada's low-carbon and high-carbon impact sectors have implemented several significant initiatives and best practices for operations. However, widespread engagement in a comprehensive manner has yet to be achieved. Many respondents were in the process of developing a more balanced risk-opportunity agenda in relation to climate change, and nearly half of all respondents have implemented governance arrangements or personal incentives in both both the high-carbon and low-carbon impact sectors. 5 tabs., 26 figs.

  6. Nuclear fuel waste policy in Canada

    International Nuclear Information System (INIS)

    The 1996 Policy Framework for Radioactive Waste established the approach in Canada for dealing with all radioactive waste, and defined the respective roles of Government and waste producers and owners. The Policy Framework sets the stage for the development of institutional and financial arrangements to implement long-term waste management solutions in a safe, environmentally sound, comprehensive, cost-effective and integrated manner. For nuclear fuel waste, a 10-year environmental review of the concept to bury nuclear fuel waste bundles at a depth of 500 m to 1000 m in stable rock of the Canadian Shield was completed in March 1998. The Review Panel found that while the concept was technically safe, it did not have the required level of public acceptability to be adopted at this time as Canada's approach for managing its nuclear fuel waste. The Panel recommended that a Waste Management Organization be established at arm's length from the nuclear industry, entirely funded by the waste producers and owners, and that it be subject to oversight by the Government. In its December 1998 Response to the Review Panel, the Government of Canada provided policy direction for the next steps towards developing Canada's approach for the long-term management of nuclear fuel waste. The Government chose to maintain the responsibility for long-term management of nuclear fuel waste close with the producers and owners of the waste. This is consistent with its 1996 Policy Framework for Radioactive Waste. This approach is also consistent with experience in many countries. In addition, the federal government identified the need for credible federal oversight. Cabinet directed the Minister of NRCan to consult with stakeholders, including the public, and return to ministers within 12 months with recommendations on means to implement federal oversight.

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

    Science.gov (United States)

    2016-07-01

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

  2. The cost of urban congestion in Canada

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2006-03-22

    A systematic analysis of urban congestion in Canada was presented. The analysis developed congestion indicators for the 9 largest urban areas in Canada. An engineering approach was used to define and to develop the congestion indicators and to estimate the social costs of congestion associated with extra time wasted due to congestion and the cost associated with greenhouse gas (GHG) emissions. The approach focused on direct and physical characteristics of congestion which linked vehicle flow and traffic speed to road capacity. An economic approach recognized that there is an economically efficient level of congestion caused by impeding users, and that some congestion is already internalized for some users. The study estimated that the total annual cost of congestion in 2002 ranged from $2.3 billion to $3.7 billion for the major urban areas in Canada. More than 90 per cent of the cost represented the value of the time lost to automobile travellers in congestion. Seven per cent of the cost represented the value of fuels consumed, and 3 per cent represented the amount of GHGs emitted under congestion conditions. The study estimated an increase of 1.2 to 1.4 megatonnes of GHG due to congestion every year. It was concluded that estimates provided in the report did not include data of costs associated with non-recurrent congestion caused by bad weather, accidents and other congestion-related costs such as noise and stress. 14 refs., 8 tabs.

  3. Basic principles of radiation protection in Canada

    International Nuclear Information System (INIS)

    The major goal of radiation protection in Canada is to ensure that individuals are adequately protected against the harm that might arise from unwarranted exposure to ionizing radiation. This report deals with the basic principles and organizations involved in protection against ionizing radiation. Three basic principles of radiation protection are: 1) that no practice shall be adopted unless its introduction produces a positive net benefit for society, 2) that all exposures shall be kept as low as reasonably achievable, relevant economic and social factors being taken into account, and 3) that doses to individuals should not exceed specified annual limits. The limit for radiation workers is currently 50 mSv per year, and exposures of the general public should not exceed a small fraction of that of radiation workers. Other specific areas in radiation protection which have received considerable attention in Canada include limitations on collective dose (the sum of the individual doses for all exposed individuals), exemption rules for extremely small radiation doses or amounts of radioactive materials, occupational hazards in uranium mining, and special rules for protection of the foetus in pregnant female radiation workers. Implementation of radiation protection principles in Canada devolves upon the Atomic Energy Control Board, the Department of National Health and Welfare, provincial authorities, licensees and radiation workers. A brief description is given of the roles of each of these groups

  4. Petro-Canada annual report, 1993

    International Nuclear Information System (INIS)

    Petro-Canada is Canada's national energy corporation, formed by an Act of Parliament in 1975. Operations began in January 1976. In 1993 net earnings were improved by $153 million to $162 million, and cash flow from operations was increased by $113 million to $630 million. The consolidation of conventional upstream activities to 150 producing entities in 26 strategic areas was completed, and remaining non-core upstream assets were grouped into a separate unit for sale. The refinery capacity reduction program was completed, and retail rationalization neared completion. Total capital and exploration expenditures of $639 million were less than cash flow of $630 million. Credit ratings and market valuation improved in recognition of the company's increased strength. This annual report presents a corporate profile, a statement of corporate responsibility, and the year's activities in production and sales of natural gas, synthetic and natural crude oil and gasoline. Details are also provided of Petro-Canada's financial and operational restructuring in view of the declining revenues being obtained.

    2010-12-01

    Full Text Available Canada faces health care challenges common to all industrialized countries – how to ensure timely access to high quality care, close to home, at an affordable cost. Addressing these challenges is complicated by interjurisdictional variation in both how health care is managed and delivered, and in health outcomes. Canada can be described as a non-system of 10 provincial and three territorial health insurance plans which mandate publicly-funded coverage for medically necessary hospital and physician services, based upon common principles and shaped by a federal governance structure that affords substantial power and autonomy to the provinces/territories over matters of health and health care. This article first examines the structural context of the health care system in Canada, including the range of services publicly funded, the public-private mix, and the complexities of current governance arrangements. It then discusses several issues affecting health policy reform: costs versus access; questions of sustainability, quality, and performance; human resources capacity; and the provision of public and population health services.

  7. Nuclear energy's continuing benefits to Canada

    International Nuclear Information System (INIS)

    The goal of the Canadian nuclear power program when it began twenty years ago was to reduce Canadian dependence on imported coal. This goal has been met, with 35 percent of Ontario's electricity being produced by CANDU reactors. These reactors have been proven reliable and safe, and provide a considerable cost advantage over coal. The CANDU reactor was developed with the strengths and limitations of Canadian industry in mind, the newest stations have over 85 percent Canadian-manufactured components. A similar benefit should be found in many countries with manufacturing capabilities comparable to Canada's. The use of natural uranium as a fuel has been a wise choice both technically and economically. A new industry was created in Canada in order to gain an assured supply of heavy water. The personnel brought to or trained in Canada to work in all parts of the nuclear industry represent a valuable asset in themselves. Radioisotope exports are making a significant contribution. Nuclear power is likely to make its greatest impact in the next century, when it will be a necessity

  8. Thallium contamination of water in Canada

    Cheam, V. [National Water Research Institute Branch, Burlington, ON (Canada). Aquatic Ecosystems Protection Research Branch

    2001-07-01

    A highly sensitive instrument, a Laser-Excited Atomic Fluorescence Spectrometer, has been developed to study thallium contamination in some important Canadian ecosystems from the Arctic (containing very low thallium concentration) to coal-related industries across Canada and even to the study of thallium toxicity in an invertebrate, Hyalella azteca. Overall, the data indicate that the coal power plants and mines contain higher thallium concentrations than the other ecosystems studied, and the eastern region has the highest Tl concentrations compared to other regions. The range of thallium concentration in ng/L for the Arctic snow and ice was between not detected and 8.4, for the Great Lakes waters 0.9 to 48, for pore waters 0.1 to 213, for western coal power plants and mines 0.1 to 1326, for central coal power plants 1.2 to 175, for eastern coal power plants and mines 0.2 to 23605, and for miscellaneous sites across Canada not detected to 4390 ng/L. Some of these high concentrations and those high ones reported in industrial wastewaters exceeded the chronic toxicity endpoints for Hyalella azteca mortality, growth and reproduction, and thus can cause serious distress to the environment. All data were integrated into a map of thallium distribution, the first one in Canada. Natural background level of thallium for the Arctic was estimated to be 0.02 to 0.03 pg/g.

  9. An emissions trading regime for Canada

    International Nuclear Information System (INIS)

    In 1998, over twelve papers were published on emissions trading regimes in Canada by the National Round Table on the Environment and the Economy (NRTEE), a federal government agency whose members represent stakeholders as varied as business, environmental groups, academics, aboriginal groups and others. One of the recommendations that emerged was for the computer modelling of the possibilities that had been identified for a domestic trading regime in Canada for greenhouse gases. It is unclear whether the modelling was ever performed as the file was taken over by the Finance Department under the umbrella of a special emission trading table that examined Canada's commitment under the Kyoto Protocol. The author examined questions pertaining to whether a domestic trading regime is essential, and what its characteristics should be in case it was deemed essential or advisable to have one. The upstream versus downstream application was looked at, as well as grand-fathering versus auction. Provincial issues were then addressed, followed by meshing with a credit system. International systems were reviewed. Early action was discussed, whereby an emitter seeks credit for action taken toward reductions since the original reference year of 1990. The case of emitters having bought or sold permits since the original reference years will also want those trades recognized under a trading regime. The author indicated that it seems probable that an emission trading system will eventually be implemented and that a debate on the issue should be initiated early

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

    International Nuclear Information System (INIS)

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

  12. Immigration in two federations: Canada and Australia.

    Atchison, J

    1988-03-01

    The need for increasingly widespread application of a policy or program, settlement, and multiculturalism is urgent in both Canada and Australia. For both countries there is a clear pattern of coalescence and divergence and the distinct growth of immigration as a federal function. While Australia has strengthened federal functions in a area of increasingly geo-political need, Canada is moving towards a looser model of federalism. By 1918 both countries were strengthening their federal functions in immigration as discussions within the British Empire on the recommendations of the 1917 Dominions Royal Commission took root. Both countries were interested in agricultural immigration and land settlement. The Great Depression caused a major reduction in population growth rates. From 1933-1948 Canada had a poor record of providing sanctuary for Jews. In Australia, however, Jewish voluntary agencies were aiding the reception of refugees by 1937. The 1st permanent embodiment of commonwealth jurisdiction over immigration was the establishment of an Immigration Branch within the Department of Interior around 1938. Australia needed extra population for defense. The major structural link between government and the immigrant communities was through the Good Neighbor Movement, which began on a nationwide basis in 1950. Both Canada and Australia are major receiving countries for refugees. In 1973 Australia reached the position of effective, practical nondiscrimination achieved by Canada in 1967. Prime Minister Trudeau's policy was multiculturalism within a framework of bilingualism. By 1978 Australia had a new federalism policy, which in all areas concerned with immigrants, refugees and ethnicity, rationalized resources allocation and imposed a political philosophy. The foci of multiculturalism in Australia are 1) community languages; 2) creation of a tolerant, non-discriminatory society; and 3) equity and participation. In 1978 Australia specified population replacement and

    Ocean Networks Canada operates two large undersea observatories that collect, archive, and deliver data in real time over the Internet. These data contribute to our understanding of the complex changes taking place on our ocean planet. Ocean Networks Canada's VENUS was the world's first cabled seafloor observatory to enable researchers anywhere to connect in real time to undersea experiments and observations. Its NEPTUNE observatory is the largest cabled ocean observatory, spanning a wide range of ocean environments. Most recently, we installed a new small observatory in the Arctic. Together, these observatories deliver "Big Data" across many disciplines in a cohesive manner using the Oceans 2.0 data management and archiving system that provides national and international users with open access to real-time and archived data while also supporting a collaborative work environment. Ocean Networks Canada operates these observatories to support science, innovation, and learning in four priority areas: study of the impact of climate change on the ocean; the exploration and understanding the unique life forms in the extreme environments of the deep ocean and below the seafloor; the exchange of heat, fluids, and gases that move throughout the ocean and atmosphere; and the dynamics of earthquakes, tsunamis, and undersea landslides. To date, the Ocean Networks Canada archive contains over 130 TB (collected over 7 years) and the current rate of data acquisition is ~50 TB per year. This data set is complex and diverse. Making these "Big Data" accessible and attractive to users is our priority. In this presentation, we share our experience as a "Big Data" institution where we deliver simple and multi-dimensional calibrated data cubes to a diverse pool of users. Ocean Networks Canada also conducts extensive user testing. Test results guide future tool design and development of "Big Data" products. We strive to bridge the gap between the raw, archived data and the needs and

  14. Very Low Head Turbine Deployment in Canada

    International Nuclear Information System (INIS)

    The Very Low Head (VLH) turbine is a recent turbine technology developed in Europe for low head sites in the 1.4 - 4.2 m range. The VLH turbine is primarily targeted for installation at existing hydraulic structures to provide a low impact, low cost, yet highly efficient solution. Over 35 VLH turbines have been successfully installed in Europe and the first VLH deployment for North America is underway at Wasdell Falls in Ontario, Canada. Deployment opportunities abound in Canada with an estimated 80,000 existing structures within North America for possible low-head hydro development. There are several new considerations and challenges for the deployment of the VLH turbine technology in Canada in adapting to the hydraulic, environmental, electrical and social requirements. Several studies were completed to determine suitable approaches and design modifications to mitigate risk and confirm turbine performance. Diverse types of existing weirs and spillways pose certain hydraulic design challenges. Physical and numerical modelling of the VLH deployment alternatives provided for performance optimization. For this application, studies characterizing the influence of upstream obstacles using water tunnel model testing as well as full-scale prototype flow dynamics testing were completed. A Cold Climate Adaptation Package (CCA) was developed to allow year-round turbine operation in ice covered rivers. The CCA package facilitates turbine extraction and accommodates ice forces, frazil ice, ad-freezing and cold temperatures that are not present at the European sites. The Permanent Magnet Generator (PMG) presents some unique challenges in meeting Canadian utility interconnection requirements. Specific attention to the frequency driver control and protection requirements resulted in a driver design with greater over-voltage capability for the PMG as well as other key attributes. Environmental studies in Europe included fish friendliness testing comprised of multiple in

    This article examines the potential for changes in imported and autochthonous malaria incidence in Canada as a consequence of climate change. Drawing on a systems framework, we qualitatively characterize and assess the potential direct and indirect impact of climate change on malaria in Canada within the context of other concurrent ecological and social trends. Competent malaria vectors currently exist in southern Canada, including within this range several major urban centres, and conditions here have historically supported endemic malaria transmission. Climate change will increase the occurrence of temperature conditions suitable for malaria transmission in Canada, which, combined with trends in international travel, immigration, drug resistance, and inexperience in both clinical and laboratory diagnosis, may increase malaria incidence in Canada and permit sporadic autochthonous cases. This conclusion challenges the general assumption of negligible malaria risk in Canada with climate change. PMID:19277107

    Full Text Available Background and objectives. Inuit populations may be at increased risk for experiencing poor nutrition or hunger due to limited access and availability to food. The prevalence and correlates of parental perceptions of hunger among a nationally representative sample of Inuit children in Canada have not yet been reported. Design. Data are from the 2006 Aboriginal Children's Survey (ACS. Sociodemographic information, dietary behaviours and hunger status were parent-reported via a household interview for Inuit children aged 2–5 years (n=1,234. Prevalence of hunger was calculated among Inuit children by sociodemographic factors and by dietary behaviours. In addition, a multivariate logistic regression model was conducted to determine factors associated with parental perception of ever experiencing hunger. Results. The prevalence of Inuit children in Canada aged 2–5 years ever experiencing hunger was 24.4%. Children who were reported to have experienced hunger consumed milk and milk products (p<0.001; fish, eggs and meat (p<0.05; fruits (p<0.001; and vegetables (p<0.001 significantly less often than never-hungry children. Fast food and processed foods, soft drinks and juice, and salty snacks, sweets and desserts were consumed as often as never-hungry children (all p>0.05. The majority (81% of Inuit parents/guardians of ever-hungry children sought help from family or friends. Factors associated with an increased likelihood of experiencing hunger include sociodemographic characteristics (such as income and household size, living in an Inuit region and living in a community with cultural activities. Conclusion. About 1 in 4 Inuit children were reported by their parents to have experienced hunger, and hunger was associated with region, sociodemographic and community factors. Future research could further examine the impact of ever experiencing hunger on the health status of Inuit children and their families in Canada.

  3. Transport of radioactive material in Canada

    International Nuclear Information System (INIS)

    In this report, the Advisory Committee on Nuclear Safety (ACNS) presents the results of its study on how the system of the transport of radioactive material (TRM) in Canada is regulated, how it operates, and how it performs. The report deals with the transport of packages, including Type B packages which are used to carry large quantities of radioactive material, but not with the transport of spent nuclear fuel or with the transport of low-level historical waste. The ACNS has examined the Canadian experience in the TRM area, the regulatory framework in Canada with respect to the TRM some relevant aspects of training workers and monitoring compliance with regulatory requirements, the state of the emergency preparedness of organizations involved in the TRM and the process of updating present regulations by the Atomic Energy Control Board (AECB). As a result of this study, the ACNS concludes that the current Canadian regulatory system in the TRM is sound and that the TRM is, for the most part, conducted safely. However, improvements can be made in a number of areas, such as: determining the exposures of workers who transport radioactive material; rewording the proposed Transport Regulations in plain language; training all appropriate personnel regarding the AECB and Transport Canada (TC) Regulations; enforcing compliance with the regulations; and increasing the level of cooperation between the federal agencies and provincial authorities involved in the inspection and emergency preparedness aspects of the TRM. It is also noted that Bill C-23, the Nuclear Safety and Control Act, imposes a new requirement, subject to the Regulations, for a licence for a carrier to transport some types of radioactive material

    A report of operational and financial achievements is reported. Shell Canada's Resources Division is one of Canada's largest producers of crude oil, natural gas, natural gas liquids, sulphur and bitumen. This report presents an operations review, provides consolidated financial statements, and common share information, and summarizes revenue and expenditure statements. The company was one of Canada's most profitable integrated oil and gas companies in 1998. It was the second most profitable year in the company's history for continuing operations. Oil products earnings for 1998 were a record $275 million, mostly because of strong sales volumes and increased retail market share. The company also confronted several environmental issues in 1998, including climate change and the reduction of greenhouse gases. Construction of the Sable Project, offshore Nova Scotia, continued on budget and on schedule to bring natural gas to market by early 2000. Plans for the three elements of the Oil Sands project (the Muskeg River mine in the Athabaska Region, an upgrader at Shell's Scotford site and the Corridor Pipeline) proceeded on schedule. The Caroline complex made its expected contribution to the company's overall performance. Improved seismic technology helped to add new reserves through Shell's interest in wells in southern Alberta. Exploration activity in northeastern British Columbia and northern Alberta produced encouraging results. The work will continue in 1999. The company plans to invest some 4.9 billion dollars over the next five years in capital expenditures. Shell remains committed to the Voluntary Challenge and Registry Program. Annual reduction of CO2 emissions increased by an estimated 800,000 tonnes

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

  6. Energy and the future : Canada's role

    International Nuclear Information System (INIS)

    The rise in global energy consumption is driven by economic growth, particularly in developing countries. It is expected that by 2030, the world population will consume 50 per cent more energy than today. This increase in global energy demand can no longer be met through the business as usual approach. Graphs depicting emerging energy demand in Asia were presented for nuclear energy, coal, natural gas, oil and renewables. The issue of how China can meet it's growing energy demand was discussed with reference to energy consumed by its industrial, agricultural, commercial, residential and transportation sectors. The author emphasized the uneven distribution of resources, where consuming areas do not coincide with producing areas. It is expected that traditional energy sources will still supply most of the world's energy need for the foreseeable future, but they will leave less of an environmental impact. The author suggested that renewable energy sources will also increase but will comprise less than 20 per cent of the world supply in 2050. The author also discussed the issue of greenhouse gas (GHG) emissions, Kyoto obligations and projections of what will happen with Kyoto post 2012. Canada's GHG record and recent environmental findings were also discussed with reference to Arctic ice coverage and the decline in average winter temperature. It was suggested that technology is the key to the energy shortage the environment and security. With declining conventional oil reserves, old nuclear technology and aging electric power technology, new technology must be used to address supply issues, distribution, interconversion, environmental impacts and risks. It was emphasized that since the energy sector is Canada's greatest economic driver, Canada should focus on energy technologies to build a more competitive energy sector. Huge export opportunities also exist for energy technologies. The role of industry and governments in achieving this goal was also discussed. figs

    This presentation provided a broad overview of the geopolitical issues affecting the massive transformation of the Arctic resulting from resource development, globalization, and climate change. Two Arctics are emerging, notably one European and one North American. Oil and gas companies are investing heavily in the North, and there is continued debate over pipelines and projects, but the viability of projects can shift abruptly from technological and political change. Recent examples include the emergence of shale gas, the possibility of the United States becoming a gas exporter, and the Deepwater Horizon disaster. In terms of Maritime jurisdictions and boundaries, a comparison was presented regarding the Canadian and Russian claims to the continental shelf. International cooperation and a commitment to peaceful means can be seen in the Ilulissat Declaration, the acceptance of the United Nations Convention of the Law of the Sea as rules, the scientific cooperation of Canada, the United States, and Denmark, and the recent boundary agreement between Russia and Norway. The positions of the main players in the new geopolitics of the North were outlined, particularly with respect to Russia, the United States, Norway, Denmark, and Canada. Their recent policy statements and developing arctic force capabilities were summarized. Canada's more assertive Arctic policy was outlined in more detail along with the country's base locations and recent security actions in the North. The main issues facing nations with interests in the North will be maritime and aerospace; understanding the new players on the scene; and new technological developments. 10 figs., 5 refs.

    Background To determine whether the pre-medical Grade Point Average (GPA), Medical College Admission Test (MCAT), Internal examinations (Block) and National Board of Medical Examiners (NBME) scores are correlated with and predict the Medical Council of Canada Qualifying Examination Part I (MCCQE-1) scores. Methods Data from 392 admitted students in the graduating classes of 2010–2013 at University of Manitoba (UofM), College of Medicine was considered. Pearson’s correlation to assess the strength of the relationship, multiple linear regression to estimate MCCQE-1 score and stepwise linear regression to investigate the amount of variance were employed. Results Complete data from 367 (94%) students were studied. The MCCQE-1 had a moderate-to-large positive correlation with NBME scores and Block scores but a low correlation with GPA and MCAT scores. The multiple linear regression model gives a good estimate of the MCCQE-1 (R2 =0.604). Stepwise regression analysis demonstrated that 59.2% of the variation in the MCCQE-1 was accounted for by the NBME, but only 1.9% by the Block exams, and negligible variation came from the GPA and the MCAT. Conclusions Amongst all the examinations used at UofM, the NBME is most closely correlated with MCCQE-1. PMID:27103953

  9. United States/Canada electricity exchanges

    Energy Technology Data Exchange (ETDEWEB)

    1979-02-01

    The United States and Canada have been cooperating in all areas of energy exchange for many years. Electrical energy has been chosen to be the focus of this study because substantial means for exchanges offer benefits that have not yet been fully exploited. There may be some bilateral benefits from additional interconnections because of the buffers which they represent against domestic imbalances. After the history of the electricity exchanges between the two countries is reviewed, opportunities and incentives and obstacles and constraints are discussed in the next two chapters. The final chapter examines procedures to resolve obstacles and minimize constraints. (MCW)

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

  14. Acid mine drainage research in Canada

    International Nuclear Information System (INIS)

    Acidic drainage resulting from base metal, precious metal, and uranium mining is the largest single environmental problems facing the Canadian mining industry today. Technologies to prevent acidic drainage from occurring in waste rock piles and tailings sites, and on the walls of open pits and underground mines, need to be developed and demonstrated. There are two grounds in Canada which have accepted this challenge: the national Mine Environment Neutral Drainage (MEND) program and the British Columbia Acid Mine Drainage (BC AMD) Task Force. This paper summarizes the activities of these two organizations

    2007-01-01

    Mortgage indebtedness has risen considerably in Canada in recent years, pushing households’ debt-to-income ratio to an all time high. In order to identify what variables explains these changes in the stock of debt, we analyze the inflow and outflow of mortgage financing. We show that the number of new mortgage loans is mostly influenced by nominal interest rates while their average value reacts only to housing price. As to the outflow of debt repayment it is sensitive to more variables. Since...

Approximately 85% of the outbreaks occurred in Alaska Native communities, particularly the Inuit of Nunavik in northern Quebec and the First Nations population of the Pacific coast of British Columbia. These populations w...

  18. Canada: National approach to ageing management

    International Nuclear Information System (INIS)

    The Canadian regulatory approach to ensuring the implementation of effective AMPs for nuclear power plants is summarized as follows. Canada currently has 22 CANDU nuclear power reactors under operating licenses issued by the Canadian Nuclear Safety Commission (CNSC). The reactors began operation between 1971 and 1993. Through operating licenses, the CNSC requires licensees to comply with a number of in-service inspection standards and regulatory documents under CNSC Safety and Control Area ‘Fitness for Service’ of SSCs. These provide extensive requirements related to understanding, controlling and managing ageing

    2016-01-01

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

  1. Interim report to the Northern Ecosystem Initiative from the Northern Ecological Monitoring and Assessment Network (EMAN-North)

    International Nuclear Information System (INIS)

    The Northern Ecological Monitoring and Assessment Network (EMAN-North) has received funding for a proposal submitted to the Northern Ecosystems Initiative (NEI) in January 2001. EMAN-North is a network that coordinates ecological monitoring in northern Canada. Its geographic scope comprises 40 per cent of the geographic area of Canada, including Yukon, Northwest Territories and Nunavut, and an area near Churchill, Manitoba. Funding was awarded because the proposed EMAN-North project addressed the NEI priority of Monitoring Ecosystem Status and Trends, and Ecosystem Impacts of Climate Change. The project was also aimed at improving the network's capacity for long-term ecological monitoring, assessment and reporting. Several activities deal specifically with ecological impacts of climate change. This paper described the need and the context for ecological monitoring in northern Canada and defined a strategic direction for EMAN-North. The project will include many individuals involved in ecological monitoring in the north to deliver information on ecosystem changes to decision-makers and the public. refs., tabs., figs

  2. Canada's first residential green power program

    International Nuclear Information System (INIS)

    A corporate review of ENMAX, Calgary's electric system was presented as one of the business case studies. This distribution utility provides service to more than 300,000 residential and commercial customers. The company also has contracts with Natural Resources Canada and Environment Canada to supply them with 'greenpower' for use in their own facilities. In an effort to meet the customer and global demand for environmental protection, and to sharpen the company's corporate image, ENMAX decided to become fully 'EcoLogo' certified. The company conducted a survey among residential consumers and found that nearly 40 per cent of the respondents were willing to pay a premium of up to $ 15 per month for green energy, if it leads to emissions reduction. Encouraged by these results, ENMAX launched a residential customer program with Vision Quest Wind Electric. Details of the promotion campaign to popularize wind energy among prospective customers is described. Success of the residential program has led to current plans to also develop a commercial program

    2006-07-01

    The Alaska natural gas pipeline project was discussed in relation to the Canadian oil and gas industry and pipeline infrastructure. Total project costs for the pipeline were estimated at approximately $20 billion. Options out of Alberta include increasing existing capacity to the west coast, as well as expanding pipeline capacity to supply midwest and east coast markets. Existing pipeline systems will be expanded, and a new pipeline from Alaska to Chicago has been proposed. The gas pipeline project is expected to be the largest private construction project in the history of North America, and will provide 6500 jobs in both the United States and Canada. Project challenges to date have included the development of relationships with Aboriginals and First Nations groups in Canada and the United States, as well as ensuring access to efficient, competitive market-based regulatory processes. Project risks to date have included capital and operating cost over-runs, regulatory and legal delays, completion risks, and commodity price risks. Stranded gas act processes were discussed, as well as fiscal contracts related to the legislative and public process. Elements of the fiscal contract were provided, as well as details of First Nations relationships and Crown consultation processes. tabs., figs.

  4. Canada as a continental supplier of energy

    International Nuclear Information System (INIS)

    The US federal objectives for a national energy grid are presented. The objectives include an effective, large liquid market with a dramatic improvement in transmission capability and economics. Other objectives include market confidence and excellent reliability and safety. This Power Point presentation describes the management of super regional transmission organizations (RTOs), and large international transmission companies (ITCs) with reference to the benefits of fully functioning ITCs. A graph depicting UK congestion costs reveals that since April 1994, customers have saved at least $700 million and shareholders have gained at least $150 million. UK controllable operating costs have halved, with a 37 per cent real reduction in transmission costs to customers. Canada is a major exporter of electricity to the United States with most of the exports going to the Northeast USA. A graph depicting Canadian versus US electricity volumes indicates that net exports have declined since 2000. Total next export in 2001 was C$2.4 bn. In 2000 it was C$3.4 bn. The Canada-Northeast USA interface capability was also presented for New Brunswick, Ontario and Quebec with exports to Main, Vermont and New York. The constraints within US transmission is the fact that transmission networks limit power flows. The author also discusses regulatory developments in the United States, with reference to RTOs, standard market design, procedural standardization, and focus by the Northeast transmission owners on developing an ITC. 2 tabs., 4 figs

  5. Physician-Assisted Death in Canada.

    Science.gov (United States)

    Browne, Alister; Russell, J S

    2016-07-01

    The Criminal Code of Canada prohibits persons from aiding or abetting suicide and consenting to have death inflicted on them. Together, these provisions have prohibited physicians from assisting patients to die. On February 6, 2015, the Supreme Court of Canada declared void these provisions insofar as they "prohibit physician-assisted death for a competent adult person who (1) clearly consents to the termination of life and (2) has a grievous and irremediable medical condition (including an illness, disease or disability) that causes enduring suffering that is intolerable to the individual in the circumstances of his or her condition." This declaration of invalidity was scheduled to take effect one year (later extended by six months) after the ruling, to give the government time to put legislation in place. We trace the history of this decision, discuss how it has forever changed the debate on physician-assisted dying, and identify the issues that must be resolved to write the legislation. Of special importance here are the topics of access, safeguards, and conscientious objection. PMID:27348822

  6. A fusion engineering program for Canada

    International Nuclear Information System (INIS)

    In 1980 the National Research Council asked DSMA ATCON Ltd., in collaboration with Ontario Hydro, the University of Toronto, and McMaster University, to evaluate concepts for a national fusion engineering program, to define a facility that could be constructed in Canada to meet the program goals, and to suggest a strategy for encouraging industrial participation. The central element of the proposed fusion engineering and development program is tritium technology, with additional emphasis on the broader field of all hydrogen isotopes and their interactions with materials. The Canadian program in the initial phase would concentrate on fusion fuel systems, materials development, equipment development, and safety and the environment. A preliminary concept for the facility required has been developed, and key organizational activities identified. The total program costs should be $1 million in the first year, rising to a steady state of $5 million from the fourth year onward. The capital cost of the research facility is estimated to be $20 million spread over three years, and its operating budget around $7 million. The program as envisioned would make use of Canada's existing tritium resources and handling experience to contribute to worldwide fusion research

  7. Neutron sources in Canada - Present and future

    Science.gov (United States)

    Dolling, G.; Lidstone, R. F.

    Canada's pre-eminent neutron source since 1957 has been the NRU reactor at Chalk River. It is unlikely to operate beyond the year 2005. In 1994, AECL prepared the case and concept for a new research reactor, the Irradiation Research Facility (IRF), to replace NRU. The IRF was developed with the dual purpose of meeting the needs of both R&D programs to support existing and advanced CANDU® designs and also of condensed matter science and materials research using extracted neutron beams. In November 1995, AECL began a pre-project engineering programme to develop the design of the facility and to begin the safety analysis and “up-front” licensing process. The dual-purpose concept continues to be pursued and the design modified, to achieve maximum performance in the most cost-effective manner. The planned neutron-beam facilities, which include a cold source and a guide hall, will greatly enhance Canada's programs of neutron-beam research and applications. The current status of the IRF design and of efforts to secure funding for the neutron-beam components will be presented.

  8. Canada's gasoline production, sales and marketing : backgrounder

    International Nuclear Information System (INIS)

    This booklet provides a variety of useful facts as general public information about gasoline, the most widely used transportation fuel in Canada. Issues such as price, quality, availability, safety and the environmental impact of gasoline are discussed. Like any unregulated commodity, gasoline prices are determined by the market forces of supply and demand. Prices can vary from place to place because of taxes, the number of service stations, delivery costs, labour costs and land costs. Taxes play the biggest role in price differences between countries. In Canada, there are 18 gasoline-producing refineries and about 13,500 service station which are owned by 30 major retail gasoline marketing companies. Currently, propane is the most common alternative to gasoline. Alcohol fuels such as ethanol and methanol are also being used more and more frequently. Refiners are working with vehicle manufacturers to find cost-effective ways to reduce emissions from cars and trucks. Blends of gasoline with ethanol or methanol reduce hydrocarbon and carbon monoxide emissions, but may increase nitrogen oxides and other emissions. Refiners are also working to define a new national standard for sulphur levels in gasoline. refs., figs

  9. Disposal of Canada's nuclear fuel waste

    International Nuclear Information System (INIS)

    In 1978, the governments of Canada and Ontario established the Nuclear Fuel Waste Management program. As of the time of the conference, the research performed by AECL was jointly funded by AECL and Ontario Hydro through the CANDU owners' group. Ontario Hydro have also done some of the research on disposal containers and vault seals. From 1978 to 1992, AECL's research and development on disposal cost about C$413 million, of which C$305 was from funds provided to AECL by the federal government, and C$77 million was from Ontario Hydro. The concept involves the construction of a waste vault 500 to 1000 metres deep in plutonic rock of the Canadian Precambrian Shield. Used fuel (or possibly solidified reprocessing waste) would be sealed into containers (of copper, titanium or special steel) and emplaced (probably in boreholes) in the vault floor, surrounded by sealing material (buffer). Disposal rooms might be excavated on more than one level. Eventually all excavated openings in the rock would be backfilled and sealed. Research is organized under the following headings: disposal container, waste form, vault seals, geosphere, surface environment, total system, assessment of environmental effects. A federal Environmental Assessment Panel is assessing the concept (holding public hearings for the purpose) and will eventually make recommendations to assist the governments of Canada and Ontario in deciding whether to accept the concept, and how to manage nuclear fuel waste. 16 refs., 1 tab., 3 figs

  10. Uranium mining in Canada and Australia

    International Nuclear Information System (INIS)

    This study compared the impact of taxation on the economic viability and competitive position of uranium mining in Canada and Australia. The evaluation is based on four types of uranium deposit and four hypothetical project models. The deposits are assumed to have been discovered and delineated, and are awaiting a mine development decision. The models, initially appraised on a before-tax basis, are then subjected to taxation in each of six jurisdictions. Several taxation criteria are assessed in each case, including after-tax measures of investment incentive, discounted tax revenues, effective tax rates, intergovernmental tax shares, and comparative tax levels. The impact of taxation is shown to be both high and variable. The taxation systems in Saskatchewan and Australia's Northern Territory generate the most government revenue and provide the lowest incentive for investment. Canada's Northwest Territories and Ontario provide the best investment incentive and collect the least amount of taxes. South Australia and Western Australia tend to be positioned between these extremes. The study demonstrates that only the very best uranium mining projects have a chance of being developed under current market conditions, and even these can be rendered uneconomic by excessive taxation regimes. It follows that exceptionally good quality targets will have to be identified to provide the economic justification for uranium exploration. These realities will likely restrict uranium exploration and development activities for some time, not an unexpected response to a market situation where low prices have been caused largely by excess supply.

  11. Breast cancer screening in Canada: a review

    International Nuclear Information System (INIS)

    Organized screening for breast cancer in Canada began in 1988 and has been implemented in all provinces and 2 of the 3 territories. Quality initiatives are promoted through national guidelines which detail best practices in various areas, including achieving quality through a client-service approach, recruitment and capacity, retention, quality of mammography, reporting, communication of results, follow-up and diagnostic workup, and program evaluation; it also offers detailed guidelines for the pathological examination and reporting of breast specimens. The Canadian Breast Cancer Data Base is a national breast cancer screening surveillance system whose objective is to collect information from provincial-screening programs. These data are used to monitor and evaluate the performance of programs and allow comparison with national and international results. A series of standardized performance indicators and targets for the evaluation of performance and quality of organized breast cancer screening programs have been developed from the data base. Although health care is a provincial responsibility in Canada, the collective reporting and comparison of results both nationally and internationally is beneficial in evaluating and refining both screening programs and individual radiologist performance. The results of Canadian performance indicators compare favourably with those of other well-established international screening programs. There are variations in performance indicators across the provinces and territories, but these differences are not extreme. (author)

  12. Proceedings of Synergy 1998 : Canada's energy congress

    International Nuclear Information System (INIS)

    The objective of this conference was to help energy companies understand what deregulation of the electricity industry means and to meet the challenges of the increasingly competitive and volatile market environment that will inevitably follow deregulation. Accordingly, individual speakers and panels addressed the likely impacts of deregulation on energy markets, strategies to capitalize on restructuring, world market developments in the post monopoly era, strategies for gas buyers, and new opportunities for small co-generation companies and independent power producers using natural gas. Other topics dealt with included predictions about the role of the regulator in the new electricity market, the allocation of stranded costs, and the effects of FERC ruling in the USA on competition in Canada. Consumer concerns were also addressed by presentations about the bottom line for consumers, the operation of the Independent Market Operator, the influence of major power consumers on restructuring, the question of reliability in the new regime, and the effects of convergence. Experiences gained with industry restructuring in California, in the United Kingdom, in the New England States, in Scandinavian countries and in New Zealand were also reviewed as background for understanding the restructuring about to go into effect in various provinces of Canada. tabs., figs

  13. Eastern Canada natural gas market development

    International Nuclear Information System (INIS)

    An overview an update of PanCanadian's exploration operations in Atlantic Canada was presented along with market delivery options. PanCanadian is one of Canada's largest natural gas producers and the most active Canadian driller with 2,479 wells. With its' 94 per cent success rate, the company is emerging as an international exploration success and is marketing energy throughout North America. In terms of marketing natural gas, PanCanadian is ranked twelfth of 68 suppliers in customer satisfaction. The company also markets about 10 per cent of western crude production and is the second largest Canadian marketer for natural gas liquids. Also, with the deregulation of electricity in Alberta, PanCanadian is constructing two 106 megawatt power plants in Alberta to provide electricity to Southern Alberta and to take advantage of the economics of energy conversion. PanCanadian also has a dominant, 20 per cent position in the Scotia Shelf and has plans for offshore processing. Graphs depicting its Deep Panuke operations and pipeline routes to market the natural gas were included. Forecast charts for natural gas demand show a steady increase in demand from 2000 to 2010. tabs., figs

    2002-01-01

    During the first half of June, heavy rains inundated northern Minnesota and southern Canada, giving rise to floods that drove hundreds of people from their homes and drenched more than 300,000 acres of prime farmland. This false-color image of the flood (right) was acquired on June 15, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The worst of the flooding occurred on the border of Canada and Minnesota along the Roseau River, which now resembles a lake in the center of the image. The town of Roseau, Minnesota, which sits in the eastern end of the newly formed lake, was hit the hardest. Nearly all the buildings in the town took heavy water damage and many residents were forced to leave. Widespread flooding across an eight county region in Minnesota has drenched nearly 300,000 to 500,000 acres of farmland altogether. Many of the farmers hit lost 100 percent of their crops and will be unable to plant again for the season. Last week, President Bush declared northern Minnesota a disaster area. Normally, the Roseau River cannot even be seen on a MODIS image (left, acquired May 21, 2002), and the surrounding area is dry. In the false-color images, sage green, rusty orange, and blue is land, and water is black. Clouds are white and pink. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC

  15. Syncrude Canada Ltd. 1998 annual report

    International Nuclear Information System (INIS)

    Syncrude Canada Ltd. operates the Syncrude Project which is a joint venture of 10 partners responsible for operating the largest crude oil-producing oil sands facility in the world. The facility provides more than 13 per cent of Canada's annual oil requirements. Syncrude's product is Syncrude Sweet Blend (SSB) which is a high quality, light, sweet crude oil. SSB is produced through an integrated process that begins with the surface mining of the oil sands. Annual SSB shipments for 1998 were 76.7 million barrels, the 17th annual record in 20 years of operation. In 1998, construction also began on the second ore train of the North Mine and its associated hydrotransport facilities. The report presents an overview of financial highlights and operating results for 1998, paying appropriate tribute to innovation that has been responsible for the continuous improvements made by the Consortium. The report also expresses the Joint Venture Partners' long-term commitment to applying the latest technology, improving workforce productivity, environmental performance, an even higher quality product, and more cost-effective ways to do business. 2 tabs

  16. Canada's uranium industry - the next decade

    International Nuclear Information System (INIS)

    Uranium is a unique commodity. It is both a metal and a fuel. It has both commercial and military uses. It yields 'clean energy' but presents environmental concerns. All of these factors have an impact on the commerce of uranium. Being a metal, uranium is extracted from ore like many other metallic minerals. As a fuel, it is subject to the vagaries of energy commodity market forces. The history of uranium in the first nuclear weapons has led to national governments carefully controlling production and sale of uranium. The spectre of radioactive contamination of the environment adds further to the public concern over the disposal of low-level radioactive wastes from uranium processing and use. There have been a number of excellent reviews on the commercial aspects of the uranium industry. In this discussion, these aspects will be briefly summarized to provide a general picture of the strengths of the Canadian uranium industry and the pressures to which it is being subjected currently. The principal thrust of this paper will be to outline Canada's resource strength and to identify some factors which will affect Canada's ability to continue holding a sizeable share of the world uranium market

  19. Energy efficiency trends in Canada -- An industrial perspective

    International Nuclear Information System (INIS)

    The objective of this paper is to explain the contribution of energy efficiency to the evolution of secondary energy use and greenhouse gas emissions in Canada. Promoting greater energy efficiency in all sectors of the economy is an important element of Canada's National Action Program on Climate Change--the federal-provincial strategy to achieve Canada's commitment to work toward stabilizing greenhouse gas emissions at 1990 levels by the year 2000. In this regard, an improved understanding of the relationship between energy efficiency, energy use and greenhouse gas emissions will assist policy makers in assessing the progress being made in addressing the issues of global climate change and sustainable development. Natural Resources Canada has developed indicators of changes in the principal factors which influence secondary energy use and emissions over time. This paper utilizes these indicators to review energy use trends in the four secondary energy use sectors (residential, commercial, industrial and transportation), with particular emphasis on the industrial sector., This review covers the period from 1990 to 1995. The year 1995 was chosen because it is the most recent year for which actual energy use data are available. The year 1990 is the base year of Canada's environmental goal, in accordance with the Framework Convention on Climate Change. A more comprehensive and detailed presentation of these indicators can be found in ''Energy Efficiency Trends in Canada'' 1990 to 1995. This report is an update of ''Energy Efficiency Trends in Canada'' which was published by Natural Resources Canada in April 1996
