Effects of gull predation and weather on survival of emperor goose goslings
Schmutz, Joel A.; Manly, Bryan F.J.; Dau, Christian P.
2001-01-01
Numbers of emperor geese (Chen canagica) have remained depressed since the mid-1980s. Despite increases in glaucous gulls (Larus hyperboreus), a primary predator of goslings, little information existed to assess whether recent patterns of gosling survival have been a major factor affecting population dynamics. We used observations of known families of emperor geese to estimate rates of gosling survival during 1993-96 on the Yukon-Kuskokwim Delta, Alaska. Survival of goslings to 30 days of age varied among years from 0.332 during 1994 to 0.708 during 1995. Survival was lowest during 1993-94, which corresponded with the years of highest frequency of disturbance of goose broods by glaucous gulls. Rainfall during early brood rearing was much higher in 1994 than other years, and this corresponded to low survival among goslings ≤5 days of age. Numbers of juveniles in families during fall staging were negatively related to rainfall during early brood rearing (n = 23 yr). Although there are no data to assess whether gosling survival in emperor geese has declined from some previous level, current survival rates of emperor goose goslings are as high as or higher than those observed in other goose species that are rapidly increasing. A proposed reduction of glaucous gull numbers by managers may not be the most effective means for increasing population growth in emperor geese.

Serial transfer of the goose parvovirus strain B, causal agent of Derzsy's gosling disease, in cultured goose-embryo fibroblast (GEF) resulted in a mutant (designated as Bav) apathogenic for both goose embryos and susceptible goslings. Goose embryos inoculated with the 38th or higher passages of strain B survived the infection, although the virus replicated in their organs. Susceptible goslings survived challenge with the Bav strain without showing symptoms, and developed normally. Only 4.2% of gosling progeny of parents vaccinated twice with strain Bav died after challenge with the virulent strain B goose parvovirus compared with 95% of gosling progeny of unvaccinated parents. Progeny of vaccinated and unvaccinated geese were placed on a farm on which Derzsy's disease was present. During the first month of life mortality was 7.7% in the progeny of vaccinated geese compared with 59.8% in the progeny of the unvaccinated geese. At 8 weeks of age the mean weight of the vaccinated goslings was 20% greater than for the unvaccinated goslings. These results indicate that the attenuated apathogenic Bav mutant is suitable for the immunisation of layers to protect their progeny by passive immunisation against Derzsy's disease.

The western Canada goose (Branta canadensis moffitti) was divided into a Rocky Mountain population (RMP) and a Pacific population (PP) on the basis of band recovery patterns examined in this study and recovery data from other investigators. Habitat information obtained from nine cooperating wildlife agencies within the RMP's range provided a base line for evaluating future changes in nesting, molting, and wintering areas. The habitat inventory indicated that none of the seasonal habitats were currently limiting the size of the RMP. The RMP's range is divided into 15 reference areas and these are briefly described. Past studies of Canada geese in the Intermountain Region are reviewed. Topics covered in the discussion of breeding biology are nesting chronology, spring population composition, breeding age, clutch size, nesting success. artificial nesting structures, and gosling survival. Much of the mortality of Canada geese occurs before the birds are fledged. Man-made nesting structures reduce losses during incubation. but research is needed on the relations between brooding sites and gosling survival. Some western Canada geese, mainly prebreeders and unsuccessful nesters, make molt migrations to and from molting areas during and after the brood-rearing season. More than half of these molt-migrants are yearlings too young to nest; there are indications that even some successful nesters leave nesting areas to molt before the fledging of their offspring. Geese 2 years old or older may serve as guides to traditional molting areas for the first-time migrants (i.e., yearlings). Lack of disturbance appears to influence selection of specific molting areas within the nesting range of moffitti, whereas movements of molters out of the Intermountain Region may be related to the evolution of this subspecies. Apparently. molters of both the PP and RMP that leave the Region go to the Northwest Territories of Canada. Although the taxonomic status of moffitti as related to the

Newcastle disease virus (NDV) and Goose parvovirus (GPV) are considered to be two of the most important and widespread viruses infecting geese. In this study, we generated a recombinant rmNA-VP3, expressing GPV VP3 using a modified goose-origin NDV NA-1 by changing the multi-basic cleavage site motif RRQKR↓F of the F protein to the dibasic motif GRQGR↓L as that of the avirulent strain LaSota as a vaccine vector. Expression of the VP3 protein in rmNA-VP3 infected cells was detected by immunofluorescence and Western blot assay. The genetic stability was examined by serially passaging 10 times in 10-day-old embryonated SPF chicken eggs. Goslings were inoculated with rmNA-VP3 showed no apparent signs of disease and developed a strong GPV and NDV neutralizing antibodies response. This is the first study demonstrating that recombinant NDV has the potential to serve as bivalent live vaccine against Goose parvovirus and Newcastle disease virus infection in birds.

Epidemiologic investigation of an outbreak of goose parvovirus infection in Sweden.
Jansson, Désirée S; Feinstein, Ricardo; Kardi, Veronika; Mató, Tamás; Palya, Vilmos
2007-06-01
An outbreak of goose parvovirus (GPV) infection on a Swedish goose farm in the spring of 2004 increased the mortality rates from 2% in the early unaffected hatches to 90% and 99% respectively in the two hatches following virus introduction and 40% in goslings hatched later in the same breeding season. In this paper we describe the clinical observations, diagnostic procedures, and epidemiologic investigation carried out to elucidate the source of the infection. The diagnosis was confirmed by serology, virus isolation, and sequence analysis of a 493-bp-long fragment of the VP1 gene. Phylogenetically the causative virus was closely related to pathogenic GPV strains isolated in 2003 and 2004 from Poland and the United Kingdom, respectively. The Swedish isolate exhibited less homology with pathogenic strains from Hungary and Asia and with attenuated vaccine strains. The epidemiologic investigation showed that the virus was first introduced to a contract farm (farm A) and then was transferred with newly hatched goslings to the farm that had submitted the birds for necropsy (index farm). The exact time and source of the virus introduction to farm A could not be determined with absolute certainty. Possible sources of the infection included backyard goose eggs that had been delivered to farm A for subcontract incubation and hatching, wild geese that frequented the flock of breeding geese on pasture on farm A, and a clutch of Canada goose eggs (Branta canadensis) that had been produced by wild geese and was hatched in the same machine as the eggs produced by farm A.

To investigate the possibility of in ovo infection with avian bornavirus (ABV) in wild Canada geese (Branta canadensis), 53 eggs were opportunistically collected at various stages of embryonic development from 16 free-ranging goose nests at a large urban zoo site where ABV infection is known to be present in this species. ABV RNA was detected in the yolk of one of three unembryonated eggs using real-time reverse transcription polymerase chain reaction. ABV RNA was not identified in the brains from 23 newly hatched goslings or 19 embryos, nor from three early whole embryos. Antibodies against ABV were not detected in the plasma of any of the hatched goslings using an enzyme-linked immunosorbent assay. Possible reasons for the failure to detect ABV RNA in hatchlings or embryos include low sample size, eggs deriving from parents not actively infected with ABV, the testing of only brain tissue, and failure of the virus to replicate in Canada goose embryos. In conclusion, this preliminary investigation demonstrating the presence of ABV RNA in the yolk of a Canada goose egg provides the first evidence for the potential for vertical transmission of ABV in waterfowl.

Canada goose nest survival at rural wetlands in north-central Iowa
Ness, Brenna N.; Klaver, Robert W.
2016-01-01
The last comprehensive nest survival study of the breeding giant Canada goose (Branta canadensis maxima) population in Iowa, USA, was conducted >30 years ago during a period of population recovery, during which available nesting habitat consisted primarily of artificial nest structures. Currently, Iowa's resident goose population is stable and nests in a variety of habitats. We analyzed the effects of available habitat on nest survival and how nest survival rates compared with those of the expanding goose population studied previously to better understand how to maintain a sustainable Canada goose population in Iowa. We documented Canada goose nest survival at rural wetland sites in north-central Iowa. We monitored 121 nests in 2013 and 149 nests in 2014 at 5 Wildlife Management Areas (WMAs) with various nesting habitats, including islands, muskrat (Ondatra zibethicus) houses, and elevated nest structures. We estimated daily nest-survival rate using the nest survival model in Program MARK. Survival was influenced by year, site, stage, presence of a camera, nest age, and an interaction between nest age and stage. Nest success rates for the 28-day incubation period by site and year combination ranged from 0.10 to 0.84. Nest survival was greatest at sites with nest structures (β = 17.34). Nest survival was negatively affected by lowered water levels at Rice Lake WMA (2013 β = −0.77, nest age β = −0.07). Timing of water-level drawdowns for shallow lake restorations may influence nest survival rates.

Broods of geese spend time feeding according to availability and quality of food plants, subject to inherent foraging and digestive constraints. We studied behavioral patterns of broods of Emperor Geese (Chen canagica) on the Yukon–Kuskokwim Delta, Alaska, and examined how feeding and alert behavior varied in relation to habitat and goose density. During 1994–1996, time spent feeding by Emperor Goose goslings and adult females was positively related to multispecies goose densities near observation blinds, and not to just Emperor Goose density. Similarly, body mass of Emperor Goose goslings was more strongly related (negatively) to multispecies goose densities than intraspecific densities. A grazing experiment in 1995 indicated that most above ground primary production by Carex subspathacea, a preferred food plant, was consumed by grazing geese. Those results demonstrate that interspecific competition for food occurred, with greatest support for goslings whose behavioral repertoire is limited primarily to feeding, digesting, and resting. Although the more abundant Cackling Canada Geese (Branta canadensis minima) differed from Emperor Geese in their preferred use of habitats during brooding rearing (Schmutz 2001), the two species occurred in equal abundance in habitats preferred by Emperor Goose broods. Thus, Cackling Canada Geese were a numerically significant competitor with Emperor Geese. Comparing these results to an earlier study, time spent feeding by goslings, adult females, and adult males were greater during 1993–1996 than during 1985–1986. During the interval between those studies, densities of Cackling Canada Geese increased two to three times whereas Emperor Goose numbers remained approximately stable, which implies that interspecific competition affected foraging behavior over a long time period. These density-dependent changes in foraging behavior and body mass indicate that interspecific competition affects nutrient acquisition and gosling

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

The influence of coyotes on an urban Canada goose population in the Chicago metropolitan area
Energy Technology Data Exchange (ETDEWEB)
Brown, Justin L.; /Ohio State U.
2007-01-01
Canada geese (Branta canadensis) have become common in many urban areas, often creating nuisance problems for human residents. The presence of urban geese has raised concerns about the spread of disease, increased erosion, excessive noise, eutrophication of waterways, and general nuisance problems. Goose populations have grown due to an increase in urbanization resulting in an abundance of high quality food (urban grass) and suitable nesting sites, as well as a decrease in some predators. I monitored nest predation in the Chicago suburbs during the 2004 and 2005 nesting seasons using 3 nest monitoring techniques to identify predators: video cameras, plasticine eggs, and sign from nest using a classification tree analysis. Of 58 nests monitored in 2004 and 286 in 2005, only raccoons (Procyon lotor) and coyotes (Canis latrans) were identified as nest predators. Raccoons were responsible for 22-25% of depredated nests, but were rarely capable of depredating nests that were actively defended by a goose. Coyotes were responsible for 75-78% of all Canada goose nest depredation and were documented killing one adult goose and feeding on several others. The coyote is a top-level predator that had increased in many metropolitan areas in recent years. To determine if coyotes were actively hunting geese or eggs during the nesting season, I analyzed coyote habitat selection between nesting and pre-nesting or post-nesting seasons. Coyote home ranges (95% Minimum Convex Polygon) were calculated for 19 coyotes to examine third order habitat selection related to goose nest abundance. A 100 m buffer (buffer habitat) was created and centered on each waterway edge and contained 90% of all nests. Coyotes showed selection for habitats during all seasons. Buffer habitat was the top ranked habitat in both pre-nesting and nesting seasons, but dropped to third ranked in post-nesting season. Habitat selection across seasons was compared using a repeated measures MANOVA. Habitat selection

Arctic foxes, lemmings, and canada goose nest survival at cape Churchill, Manitoba
Reiter, M.E.; Andersen, D.E.
2011-01-01
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.

Full Text Available The extent to which species are plastic in the timing of their reproductive events relative to phenology suggests how climate change might affect their demography. An ecological mismatch between the timing of hatch for avian species and the peak availability in quality and quantity of forage for rapidly growing offspring might ultimately affect recruitment to the breeding population unless individuals can adjust the timing of breeding to adapt to changing phenology. We evaluated effects of goose density, hatch timing relative to forage plant phenology, and weather indices on annual growth of pre-fledging Canada geese (Branta canadensis from 1993-2010 at Akimiski Island, Nunavut. We found effects of both density and hatch timing relative to forage plant phenology; the earlier that eggs hatched relative to forage plant phenology, the larger the mean gosling size near fledging. Goslings were smallest in years when hatch was latest relative to forage plant phenology, and when local abundance of breeding adults was highest. We found no evidence for a trend in relative hatch timing, but it was apparent that in early springs, Canada geese tended to hatch later relative to vegetation phenology, suggesting that geese were not always able to adjust the timing of nesting as rapidly as vegetation phenology was advanced. Analyses using forage biomass information revealed a positive relationship between gosling size and per capita biomass availability, suggesting a causal mechanism for the density effect. The effects of weather parameters explained additional variation in mean annual gosling size, although total June and July rainfall had a small additive effect on gosling size. Modelling of annual first-year survival probability using mean annual gosling size as an annual covariate revealed a positive relationship, suggesting that reduced gosling growth negatively impacts recruitment.

Identification of linear B-cell epitopes on goose parvovirus non-structural protein.
Yu, Tian-Fei; Ma, Bo; Wang, Jun-Wei
2016-10-15
Goose parvovirus (GPV) infection can cause a highly contagious and lethal disease in goslings and muscovy ducklings which is widespread in all major goose (Anser anser) and Muscovy duck (Cairina moschata) farming countries, leading to a huge economic loss. Humoral immune responses play a major role in GPV immune protection during GPV infection. However, it is still unknown for the localization and immunological characteristics of B-cell epitopes on GPV non-structural protein (NSP). Therefore, in this study, the epitopes on the NSP of GPV were identified by means of overlapping peptides expressed in Escherichia coli in combination with Western blot. The results showed that the antigenic epitopes on the GPV NSP were predominantly localized in the C-terminal (aa 485-627), and especially, the fragment NS (498-532) was strongly positive. These results may facilitate future investigations on the function of NSP of GPV and the development of immunoassays for the diagnosis of GPV infection. Copyright © 2016. Published by Elsevier B.V.

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

An assay protocol based on a monoclonal antibody-based competitive enzyme-linked immunosorbent assay (MAb-based C-ELISA) for detecting antibodies against goose parvovirus (GPV) and its virus-like particles (VLPs) is described. The assay was developed using baculovirus-expressed recombinant VP2 virus-like particles (rVP2-VLPs) as antigens and a monoclonal antibody against GPV as the competitive antibody. Of the four anti-GPV MAbs that were screened, MAb 1G3 was selected as it was blocked by the GPV positive serum. Based on the distribution of percent inhibition (PI) of the known negative sera (n=225), a cut-off value was set at 36% inhibition. Using this cut-off value, the sensitivity of the assay was 93.3% and the specificity was 95.8%, as compared with the gold standard (virus neutralization assay). The rVP2-VLPs did not react with anti-sera to other goose pathogens, indicating that it is specific for the recognization of goose parvovirus antibodies. The assay was then validated with serum samples from goslings vaccinated with several VLPs (rVP1-VLPs, rVP2-VLPs, rVP3-VLPs, and rCGV-VLPs) and other vaccines (inactivated and attenuated). The C-ELISA described in this study is a sensitive and specific diagnostic test and should have wide applications for the sero-diagnosis and immunologic surveillance of GPV.

Leucocytozoonosis in Canada Geese at the Seney National Wildlife Refuge
Herman, C.M.; Barrow, J.H.; Tarshis, I.B.
1975-01-01
A history is given of the Seney National Wildlife Refuge and the losses of goslings of Canada geese (Branta canadensis) recorded since inception of the refuge in 1935. Since 1960, when more reliable data became available, losses have been extensive every 4 years. Gosling deaths are attributed to the infection with Leucocytozoon simondi. The blackfly (Simulium innocens) is considered to be the prime vector in the transmission of this blood parasite to goslings.

Kerr Hydroelectric Dam is located at the south end of Flathead Lake, controls water levels on the lake and the Flathead River below the dam, and is currently operated as a load control facility. Current operation of Kerr Dam creates the greatest yearly water level fluctuations on both the lake and river during the Canada goose (Branta canadensis moffitti) brood and nesting period. Data collected from 1980-1982 indicated that goose nest numbers on the river were lower than during the 1950's, and that brood habitat on the lake may be limiting the goose population there. Our study was conducted from 1983-1987 to determine the effects of Kerr Dam operation on Canada goose populations and habitat on the south half of Flathead Lake and the Flathead River, and to formulate management and mitigation recommendations. Nesting geese on the river appeared to be negatively affected by a lack of nest sites free from predators, and responded to available artificial nest structures with an increase in nest numbers and nesting success. Under current dam operation, river channel depths and widths do not discourage access to nesting islands by mammalian predators during some years and high predation on ground nests occurs. Intensively used brood areas on the lake and river were identified and described. Brood habitat on the lake was lower in quality and quantity than on the river due to dam operations. Gosling mortality on the lake was high, almost 2 times higher than on the river. Lake broods expended more energy obtaining food than river broods. Losses of brood habitat in the form of wet meadow marshes were documented and mitigation options developed. Management/mitigation alternatives and monitoring methods for nesting and brooding geese were identified.

Sequencing and generation of an infectious clone of the pathogenic goose parvovirus strain LH.
Wang, Jianye; Duan, Jinkun; Zhu, Liqian; Jiang, Zhiwei; Zhu, Guoqiang
2015-03-01
In this study, the complete genome of the virulent strain LH of goose parvovirus (GPV) was sequenced and cloned into the pBluescript II (SK) plasmid vector. Sequence alignments of the inverted terminal repeats (ITR) of GPV strains revealed a common 14-nt-pair deletion in the stem of the palindromic structure in the LH strain and three other strains isolated after 1982 when compared to three GPV strains isolated earlier than that time. Transfection of 11-day-old embryonated goose eggs with the plasmid pLH, which contains the entire genome of strain LH, resulted in successful rescue of the infectious virus. Death of embryos after transfection via the chorioallantoic membrane infiltration route occurred earlier than when transfection was done via the allantoic cavity inoculation route. The rescued virus exhibited virulence similar to that of its parental virus, as evaluated by the mortality rate in goslings. Generation of the pathogenic infectious clone provides us with a powerful tool to elucidate the molecular pathogenesis of GPV in the future.

Incidence of trypanosomes in the Canada goose as revealed by bone marrow culture
Diamond, L.S.; Herman, C.M.
1954-01-01
1. Techniques are described for the cultural isolation of trypanosomes from avian bone marrow obtained from living birds or at autopsy. A new medium SNB-9 (saline-neopeptone-blood) is described. In addition to being a good medium for growing avian trypanosomes, it is excellent for growing trypanosomes of amphibians and mammals. 2. Evidence is presented demonstrating the superiority of (a) cultures over stained smears for detecting the presence of trypanosomes in the Canada goose, and (b) bone marrow over heart blood of this species as a source of trypanosomes for culture. 3. In April 1952, from cultures of bone marrow collected at autopsy it was demonstrated that trypanosome infection occurred in 33 (40.2%) of 82 Canada geese from the Pea Island National Wildlife Refuge. On February 17, 1953, cultures of bone marrow obtained from living birds revealed presence of trypanosomes in 12 (20.7%) of 58 geese from the same refuge. On February 26, 1953, by employing the latter method, 9 (20.4%) of 44 geese from Blackwater National Wildlife Refuge were shown to harbor the parasites. In another survey ninety-two geese from seven national wildlife refuges subjected to the biopsy technique showed evidence of infection in 13 (14.1 %) birds and indicated that trypanosome infection is widely distributed in this host.

Intercolony variation in growth of black brant goslings on the Yukon-Kuskokwim Delta, Alaska
Fondell, T.F.; Flint, Paul L.; Sedinger, J.S.; Nicolai, C.A.; Schamber, J.L.
2011-01-01
Recent declines in black brant (Branta bernicla nigricans) are likely the result of low recruitment. In geese, recruitment is strongly affected by habitat conditions experienced by broods because gosling growth rates are indicative of forage conditions during brood rearing and strongly influence future survival and productivity. In 2006–2008, we studied gosling growth at 3 of the 4 major colonies on the Yukon‐Kuskokwim Delta, Alaska. Estimates of age‐adjusted gosling mass at the 2 southern colonies (approx. 30% of the world population of breeding black brant) was low (gosling mass at 30.5 days ranged 346.7 ± 42.5 g to 627.1 ± 15.9 g) in comparison to a third colony (gosling mass at 30.5 days ranged 640.0 ± 8.3 g to 821.6 ± 13.6 g) and to most previous estimates of age‐adjusted mass of brant goslings. Thus, our results are consistent with the hypothesis that poor gosling growth is negatively influencing the brant population. There are 2 non‐mutually exclusive explanations for the apparent growth rates we observed. First, the population decline may have been caused by density‐independent factors and habitat capacity has declined along with the population as a consequence of the unique foraging feedback between brant and their grazing habitats. Alternatively, a reduction in habitat capacity, as a result of changes to the grazing system, may have negatively influenced gosling growth, which is contributing to the overall long‐term population decline. We found support for both explanations. For colonies over habitat capacity we recommend management to enhance foraging habitat, whereas for colonies below habitat capacity we recommend management to increase nesting productivity.

Genetic evaluation of reproductive potential in the Zatorska goose under a conservation program.
Graczyk, Magdalena; Andres, Krzysztof; Kapkowska, Ewa; Szwaczkowski, Tomasz
2018-05-01
The aim of this study was to estimate the genetic parameters and inbreeding effect on the fertility, embryo mortality and hatchability traits in the Zatorska goose covered by the animal genetic resources conservation program. The material for this study contains information about results of hatching of 18 863 eggs from 721 dams and 168 sires, laid between 1998-2015. Genetic parameters were estimated based on the threshold animal model by the use of Restricted Maximum Likelihood and Gibbs sampling. The percentage of fertilized eggs ranged yearly between 37-80%. The percentage of embryo mortality was very low, ranging between 4.63-23.73%. The percentage of the hatched goslings from the total number of analyzed eggs was on average 33.18%, and 53.72% from fertilized eggs. On average based on both methods, the heritability estimates of the fertility, embryo mortality and hatchability reached 0.36, 0.07, 0.24 for males and 0.44, 0.11, 0.32 for females. The genetic trend had increasing tendency for fertility and hatchability and was stable for embryo mortality for both sexes. The obtained result shows that the Zatorska goose can be still maintained in the reserves of the local gene pool according to current rules and use in the local market as a breed with good reproductive potential. © 2018 Japanese Society of Animal Science.

Twenty-one, 25-day-old, artificially reared, coccidia-free goslings (Anser cygnoides var. domestica) were inoculated orally with 0.5 × 10 4 , 1 × 10 4 , or 100 × 10 4 sporulated oocysts of Eimeria anseris and sacrificed at intervals from 24 to 216 h post-inoculation (HPI). Nine uninfected goslings served as negative controls. Parts of the visceral organs from goslings, including the intestines, kidneys, and liver, were fixed, sectioned, and observed microscopically. The results revealed that two generations of meronts occurred in the life cycle of E. anseris. The first generation of meronts developed at 24-96 HPI and the second generation at 90-128 HPI. Each meront contained 4-10 merozoites. Development of gamonts began at 128 HPI and mature oocysts appeared at 168 HPI. Developmental stages presented mainly in the epithelial cells of crypts and lamina propria in the posterior parts of the jejunum and ileum. Parasites localized mostly in the cytoplasm and occasionally in the nuclei of host cells. Histological lesions were pronounced in the jejunum and ileum. Desquamation and necrosis of the epithelium of intestine and crypts, infiltration of inflammatory cells, and hemorrhage and mucosal edema were associated with aggregates of endogenous stages. The infected goslings mainly showed severe diarrhea, depression, anorexia, and emaciation, suggesting that E. anseris is highly pathogenic in goslings.

Background Sound decisions on control actions for established invasive alien species (IAS) require information on ecological as well as socio-economic impact of the species and of its management. Cost-benefit analysis provides part of this information, yet has received relatively little attention in the scientific literature on IAS. Methods We apply a bio-economic model in a cost-benefit analysis framework to greater Canada goose Branta canadensis, an IAS with documented social, economic and ecological impacts in Flanders (northern Belgium). We compared a business as usual (BAU) scenario which involved non-coordinated hunting and egg destruction with an enhanced scenario based on a continuation of these activities but supplemented with coordinated capture of moulting birds. To assess population growth under the BAU scenario we fitted a logistic growth model to the observed pre-moult capture population. Projected damage costs included water eutrophication and damage to cultivated grasslands and were calculated for all scenarios. Management costs of the moult captures were based on a representative average of the actual cost of planning and executing moult captures. Results Comparing the scenarios with different capture rates, different costs for eutrophication and various discount rates, showed avoided damage costs were in the range of 21.15 M€ to 45.82 M€ under the moult capture scenario. The lowest value for the avoided costs applied to the scenario where we lowered the capture rate by 10%. The highest value occurred in the scenario where we lowered the real discount rate from 4% to 2.5%. Discussion The reduction in damage costs always outweighed the additional management costs of moult captures. Therefore, additional coordinated moult captures could be applied to limit the negative economic impact of greater Canada goose at a regional scale. We further discuss the strengths and weaknesses of our approach and its potential application to other IAS. PMID

The goose parvovirus (GPV) Rep1 protein is both essential for viral replication and a potential target for GPV diagnosis, but its protein characterization and intracellular localization is not clear. We constructed a recombinant plasmid, pET28a/GPV-Rep1, and expressed the Rep1 gene in BL21 (DE3) Escherichia coli. A protein approximately 75 kDa in size was obtained from lysates of E. coli cells expressing the recombinant plasmid. SDS-PAGE analysis showed that after induction with 0.6 mM isopropyl β-D-thiogalactosidase (IPTG) at 30°C for 5 h, the Rep1 protein was highly overexpressed. Two methods used to purify proteins, a salinity-gradient elution and Ni-NTA affinity chromatography, were performed. The amount of Rep1 protein obtained by Ni-NTA affinity chromatography was 41.23 mg, while 119.9 mg of Rep1 protein was obtained by a salinity-gradient elution from a 1 L E. coli BL21 (DE3) culture. An immunogenicity analysis showed that the protein could significantly elicit a specific antibody response in immunized goslings compared to control groups. Antibody titers peaked to 1:5120 (optical density (OD) 450 = 3.9) on day 28 after immunization but had mean titers of 1:10,240 (OD450 = 4.2) in gosling groups immunized with a commercially available GPV-attenuated vaccine strain. Experiments examining subcellular localization showed that the Rep1 protein appeared to associate predominantly with the nuclear membrane, especially during later times of infection. This work provides a basis for biochemical and structural studies on the GPV Rep1 protein.

The genomic structure and composition of an avian metapneumovirus (aMPV) recently isolated from wild Canada geese (goose 15a/01) in the United States, together with its replication, virulence, and immunogenicity in domestic turkeys, were investigated. The sizes of seven of the eight genes, sequence identity, and genome organization of goose aMPV were similar to those of turkey aMPV subtype C (aMPV/C) strains, indicating that it belonged to the subtype. However, the goose virus contained the largest attachment (G) gene of any pneumovirus or metapneumovirus, with the predicted G protein of 585 amino acids (aa) more than twice the sizes of G proteins from other subtype C viruses and human metapneumovirus and more than 170 aa larger than the G proteins from the other aMPV subtypes (subtypes A, B, and D). The large G gene resulted from a 1,015-nucleotide insertion at 18 nucleotides upstream of the termination signal of the turkey aMPV/C G gene. Three other aMPV isolates from Canada geese had similarly large G genes, whereas analysis of recent aMPV strains circulating in U.S. turkeys did not indicate the presence of the goose virus-like strain. In vitro, the goose virus replicated to levels (2 × 105 to 5 × 105 50% tissue culture infective dose) comparable to those produced by turkey aMPV/C strains. More importantly, the virus replicated efficiently in the upper respiratory tract of domestic turkeys but with no clinical signs in either day-old or 2-week-old turkeys. The virus was also horizontally transmitted to naïve birds, and turkey infections with goose 15a/01 induced production of aMPV-specific antibodies. Challenging day-old or 2-week-old turkeys vaccinated with live goose aMPV resulted in lower clinical scores in 33% of the birds, whereas the rest of the birds had no detectable clinical signs of the upper respiratory disease, suggesting that the mutant virus may be a safe and effective vaccine against aMPV infection outbreaks in commercial turkeys.

Adeno-associated virus type 2 enhances goose parvovirus replication in embryonated goose eggs
International Nuclear Information System (INIS)
Malkinson, Mertyn; Winocour, Ernest
2005-01-01
The autonomous goose parvovirus (GPV) and the human helper-dependent adeno-associated virus type 2 (AAV2) share a high degree of homology. To determine if this evolutionary relationship has a biological impact, we studied viral replication in human 293 cells and in embryonated goose eggs coinfected with both viruses. Similar experiments were performed with the minute virus of mice (MVM), an autonomous murine parvovirus with less homology to AAV2. In human 293 cells, both GPV and MVM augmented AAV2 replication. In contrast, AAV2 markedly enhanced GPV replication in embryonated goose eggs under conditions where a similar effect was not observed with MVM. AAV2 did not replicate in embryonated goose eggs and AAV2 inactivated by UV-irradiation also enhanced GPV replication. To our knowledge, this is the first report that a human helper-dependent member of the Parvoviridae can provide helper activity for an autonomous parvovirus in a natural host

Immunogenicity of virus-like particles containing modified goose parvovirus VP2 protein.
Chen, Zongyan; Li, Chuanfeng; Zhu, Yingqi; Wang, Binbin; Meng, Chunchun; Liu, Guangqing
2012-10-01
The major capsid protein VP2 of goose parvovirus (GPV) expressed using a baculovirus expression system (BES) assembles into virus-like particles (VLPs). To optimize VP2 gene expression in Sf9 cells, we converted wild-type VP2 (VP2) codons into codons that are more common in insect genes. This change greatly increased VP2 protein production in Sf9 cells. The protein generated from the codon-optimized VP2 (optVP2) was detected by immunoblotting and an indirect immunofluorescence assay (IFA). Transmission electron microscopy analysis revealed the formation of VLPs. These findings indicate that optVP2 yielded stable and high-quality VLPs. Immunogenicity assays revealed that the VLPs are highly immunogenic, elicit a high level of neutralizing antibodies and provide protection against lethal challenge. The antibody levels appeared to be directly related to the number of GP-Ag-positive hepatocytes. The variation trends for GP-Ag-positive hepatocytes were similar in the vaccine groups. In comparison with the control group, the optVP2 VLPs groups exhibited obviously better responses. These data indicate that the VLPs retained immunoreactivity and had strong immunogenicity in susceptible geese. Thus, GPV optVP2 appears to be a good candidate for the vaccination of goslings.

The glycoprotein (G) gene sequences of avian metapneumovirus (aMPV) subtypes A, B, C, and D are variable in size and number of nucleotides. The G gene of early U.S. turkey isolates of aMPV-C have been reported to be 1798 nucleotides (nt) (585 aa) in length, whereas the G genes of more recent turkey isolates have been reported to be 783 nucleotides. In some studies, the G gene of aMPV-C turkey isolates was found to be truncated to a smaller G gene of 783 nt (261 aa) upon serial passages in Vero cells. This is believed to be due to the deletion of 1015 nt near the end of the open reading frame. The purpose of this study was to determine variation, if any, in the G gene of an aMPV-C isolated from a wild bird (Canada goose [Branta canadensis]) following serial passages in Vero cells. No size variation was observed for up to 50 passages, except for a few amino acid changes in the extracellular domain at the 50th passage level. The G gene of this wild bird isolate appears to be unique from subtype C metapneumoviruses of turkeys.

Experimental Study on the Geometrical and Mechanical Properties of Goose Eggshells
Directory of Open Access Journals (Sweden)
J Zhang
Full Text Available ABSTRACT This paper examined the properties of goose eggshells to determine possible areas of improvement in egg transport and storage. First, we measured goose egg sizes and performed statistical tests, and found that the major axis, minor axis, and egg-shape index presented normal distribution. Eggshell thickness first increased and then decreased from the blunt end to the sharp end. Second, the shape of individual goose eggshell was measured using a 3D scanner. Volume equation, surface equation, and contour function of goose eggshell shape were obtained, exhibiting a highly symmetrical structure. Finally, goose eggs were compressed along their major and minor axes between two plates. Breaking strength was highly dependent on the shape index. A crack was found on the force point along the major axis of each goose egg.

A full understanding of population dynamics depends not only on estimation of mechanistic contributions of recruitment and survival, but also knowledge about the ecological processes that drive each of these vital rates. The process of recruitment in particular may be protracted over several years, and can depend on numerous ecological complexities until sexually mature adulthood is attained. We addressed long-term declines (23 breeding seasons, 1992–2014) in the per capita production of young by both Ross's Geese (Chen rossii) and Lesser Snow Geese (Chen caerulescens caerulescens) nesting at Karrak Lake in Canada's central Arctic. During this period, there was a contemporaneous increase from 0.4 to 1.1 million adults nesting at this colony. We evaluated whether (1) density-dependent nutritional deficiencies of pre-breeding females or (2) phenological mismatch between peak gosling hatch and peak forage quality, inferred from NDVI on the brood-rearing areas, may have been behind decadal declines in the per capita production of goslings. We found that, in years when pre-breeding females arrived to the nesting grounds with diminished nutrient reserves, the proportional composition of young during brood-rearing was reduced for both species. Furthermore, increased mismatch between peak gosling hatch and peak forage quality contributed additively to further declines in gosling production, in addition to declines caused by delayed nesting with associated subsequent negative effects on clutch size and nest success. The degree of mismatch increased over the course of our study because of advanced vegetation phenology without a corresponding advance in Goose nesting phenology. Vegetation phenology was significantly earlier in years with warm surface air temperatures measured in spring (i.e., 25 May–30 June). We suggest that both increased phenological mismatch and reduced nutritional condition of arriving females were behind declines in population-level recruitment

Hawaiian Goose (Branta sandvicensis)
Banko, Paul C.; Black, Jeffrey M.; Banko, Winston E.
1999-01-01
Evolving in the remote Hawaiian Archipelago and having the smallest range of any living goose, the Hawaiian Goose, or better known by its Hawaiian name—Nënë, is among the most isolated, sedentary, and threatened of waterfowl. The Nënë is also highly terrestrial, and several structural features demonstrate its adaptation to life on islands with limited freshwater habitat: It stands taller and more upright than geese of similar weight, enabling it to reach high to browse the fruits, seeds, and foliage that constitute its herbivorous diet; its legs and padded toes are long and strong, promoting swift, sure walking and running over rugged terrain; webbing is reduced between the toes; and though it is a capable swimmer and readily uses freshwater habitats when available, the Nënë does not require freshwater or oceanic habitats in the same way that many other waterfowl do.

Full Text Available Newcastle disease (ND, caused by virulent strains of Newcastle disease virus (NDV, is a highly contagious disease of birds that is responsible for heavy economic losses for the poultry industry worldwide. However, little is known about host-virus interactions in waterfowl, goose. In this study, we aim to characterize the host immune response in goose, based on the previous reports on the host response to NDV in chickens. Here, we evaluated viral replication and mRNA expression of 27 immune-related genes in 10 tissues of geese challenged with a genotype VIId NDV strain of goose origin (go/CH/LHLJ/1/06. The virus showed early replication, especially in digestive and immune tissues. The expression profiles showed up-regulation of Toll-like receptor (TLR1–3, 5, 7 and 15, avian β-defensin (AvBD 5–7, 10, 12 and 16, cytokines interleukin (IL-8, IL-18, IL-1β and interferon-γ, inducible NO synthase (iNOS, and MHC class I in some tissues of geese in response to NDV. In contrast, NDV infection suppressed expression of AvBD1 in cecal tonsil of geese. Moreover, we observed a highly positive correlation between viral replication and host mRNA expressions of TLR1-5 and 7, AvBD4-6, 10 and 12, all the cytokines measured, MHC class I, FAS ligand, and iNOS, mainly at 72 h post-infection. Taken together, these results demonstrated that NDV infection induces strong innate immune responses and intense inflammatory responses at early stage in goose which may associate with the viral pathogenesis.

1992-01-01
A prototype software package for a fully interactive Generalized Object-Oriented Simulation Environment (GOOSE) is being developed at Oak Ridge National Laboratory. Dynamic models are easily constructed and tested; fully interactive capabilities allow the user to alter model parameters and complexity without recompilation. This environment provides assess to powerful tools such as numerical integration packages, graphical displays, and online help. In GOOSE, portability has been achieved by creating the environment in Objective-C 1 , which is supported by a variety of platforms including UNIX and DOS. GOOSE Version 1.4 introduces new enhancements like the capability of creating ''initial,'' ''dynamic,'' and ''digital'' methods. The object-oriented approach to simulation used in GOOSE combines the concept of modularity with the additional features of allowing precompilation, optimization, testing, and validation of individual modules. Once a library of classes has been defined and compiled, models can be built and modified without recompilation. GOOSE Version 1.4 is primarily command-line driven

Full Text Available Objective The aim of this study was to compare carcass traits, meat quality and sensory attributes in two different genotypes of geese according to age and sex. Methods The experiment was carried out on 160 birds of two genotypes of geese: the Czech Goose (CG breed and a Eskildsen Schwer (ES hybrid. One-d-old goslings were divided into four groups according to genotype and sex. Two dates for slaughtering (at 8 and 16 wk of age of goslings were undertaken. Results The slaughter weight, cold carcass weight and dressing percentage were affected by all the studied factors, and significant interactions between age, genotype and sex were detected in the slaughter weight (p<0.001 and cold carcass weight (p = 0.004. The pH was not affected by any of studied factors, whereas in terms of meat colour parameters there were observed significant effects of age on L* and b* value and a significant effect of sex on a* value. The meat fat content was higher (p = 0.002 in ES. Higher score for overall acceptance of goose meat was recorded for ES at both ages compared to CG. Conclusion ES had higher dressing percentage and better sensory attributes, whereas CG exceled in the favourable nutritional value of the meat.

Effect of protective atmosphere on color of goose meat.
Orkusz, A; Woloszyn, J; Haraf, G; Okruszek, A
2013-08-01
The objective of the work was to characterize the color of the of the goose breast meat packaged in protective atmosphere and stored in the refrigerated conditions. The aim was realized by determination of total heme pigment concentration; relative concentration of myoglobin, oxymyoglobin, and metmyoglobin; parameters of color L* (lightness), a* (redness), and b* (yellowness); and sensory evaluation of the surface color. The experimental material was White Kołuda goose boneless breast meat with the skin from industrial slaughter. The following 2 protective atmospheres were used in the study: vacuum and modified atmosphere (MA) consisting of 80% O2 and 20% CO2. The muscles packed in protective atmosphere were examined on d 4, 7, 11, and 14 of storage. A control sample was goose breast meat stored in air and tested after 24 h after slaughter. The total pigment concentration decreased gradually within 14 d of storage for samples packed in 2 types of atmospheres. The increase in relative concentration of metmyoglobin and the decrease in oxymyoglobin relative concentration in total heme pigments in the meat stored in MA was noticed. However, in all times of storage, the relative concentration of the 3 samples of myoglobin forms stored in vacuum was unchanged. The color parameters (L*, a*, b*) did not change for 14 d of storage in the muscles packed in vacuum. One can state a decrease of the value of the color parameter a* as well as an increase of the value of the color parameter b* in the samples packed in MA. From d 11 to 14 of storage, goose meat packed under MA had lower sensory evaluation intensity of color than muscles under vacuum. The obtained data indicated that the surface color of goose breast meat packed in MA (consisting of 80% O2, 20% CO2) or vacuum packed was maintained for 11 and 14 d, respectively.

This paper presents results from a multidisciplinary study of a negotiation process between farmers and wildlife authorities which led to an agricultural subsidy scheme to alleviate conflicts between agriculture and geese in Norway. The Svalbard-breeding population of pink-footed geese Anser brachyrhynchus has increased considerably over the last decades and conflicts with farmers have escalated, especially at stopover sites in spring when geese feed on newly sprouted pasture grass. In Vesterålen, an important stopover site for geese in North Norway, farmers deployed scaring of geese at varying intensity dependent on the level of conflict during 1988-2012. We assessed the efficiency of a subsidy scheme established in 2006, in terms of its conflict mitigation, reflected in a near discontinuation of scaring activities. The presence of pink-footed geese was analysed in relation to scaring intensity, the total goose population size and the increasing occurrence of another goose species, the barnacle goose Branta leucopsis. Scaring significantly affected the number of geese staging in Vesterålen, both in absolute and relative terms (controlling for total population size). The geese responded immediately to an increased, and reduced, level of scaring. Despite the establishment of the subsidy scheme, the number of pink-footed geese has recently declined which is probably caused by the increasing number of barnacle geese. For the farmers, the subsidy scheme provides funding that reduces the economic costs caused by the geese. Sustaining a low level of conflict will require close monitoring, dialogue and adaptation of the subsidy scheme to cater for changes in goose population dynamics.

While concern grows over the increasing numbers of exotic mute swans (Cygnus olor) on the Chesapeake Bay, less attention seems to be given to the highly familiar and native Canada goose (Branta canadensis) which has over time developed unprecedented nonmigratory, or resident, populations. Although nuisance flocks of Canada geese have been well advertised at city parks, athletic fields, and golf courses over the past three decades, recent expansion of populations to an estimated one million birds in the Atlantic Flyway, and to over 100,000 in Maryland, carries a threat of broader ecological consequences.

This paper presents results from a multidisciplinary study of a negotiation process between farmers and wildlife authorities which led to an agricultural subsidy scheme to alleviate conflicts between agriculture and geese in Norway. The Svalbard-breeding population of pink-footed geese Anser brachyrhynchus has increased considerably over the last decades and conflicts with farmers have escalated, especially at stopover sites in spring when geese feed on newly sprouted pasture grass. In Vesterålen, an important stopover site for geese in North Norway, farmers deployed scaring of geese at varying intensity dependent on the level of conflict during 1988–2012. We assessed the efficiency of a subsidy scheme established in 2006, in terms of its conflict mitigation, reflected in a near discontinuation of scaring activities. The presence of pink-footed geese was analysed in relation to scaring intensity, the total goose population size and the increasing occurrence of another goose species, the barnacle goose Branta leucopsis. Scaring significantly affected the number of geese staging in Vesterålen, both in absolute and relative terms (controlling for total population size). The geese responded immediately to an increased, and reduced, level of scaring. Despite the establishment of the subsidy scheme, the number of pink-footed geese has recently declined which is probably caused by the increasing number of barnacle geese. For the farmers, the subsidy scheme provides funding that reduces the economic costs caused by the geese. Sustaining a low level of conflict will require close monitoring, dialogue and adaptation of the subsidy scheme to cater for changes in goose population dynamics. PMID:23977175

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

Fat accumulation in the liver is a natural process in goose, which prepares goose for long-distance migration. In contrast to mammalian fatty liver that usually progresses into an irreversible status, steatohepatitis, goose fatty liver can return to normal without obvious pathological damage, suggesting a protective system exists in goose liver. This study was to identify the components of this system. We first focused on goose adiponectin receptor 1 and 2 (Adipor1/2) as they have ceramidase activity, and can cleave ceramide, a group of proinflammatory signaling lipid species. Quantitative analysis indicated that tumor necrosis factor alpha (Tnfα), a key proinflammatory cytokine, was down-regulated in goose fatty liver by overfeeding. This inhibition of Tnfα was accompanied with reduced adiponectin and increased Adipor1/2 in the adipose tissues and in the livers of the overfed geese, respectively. To investigate the regulation of goose Adipor2 in the context of fatty liver, we treated goose primary hepatocytes with fatty liver associated factors. Data indicated that Adipor2 was upregulated by glucose and oleate but not palmitate. Its expression was even suppressed by high level of insulin. The regulation of Adipor1 by these factors was quite similar to that of Adipor2 except that glucose did not induce Adipor1. Together, these findings suggest the upregulation of Adipor1/2 may, at least partially, contribute to the inhibition of inflammation in goose fatty liver, and the expression of Adipor1/2 can be regulated by fatty liver-associated factors.

The New Jersey Meadowlands are located within the heavily urbanized New York/New Jersey Harbor Estuary and have been subject to contamination due to effluent and runoff from industry, traffic, and homes along the Hackensack River and nearby waterways. These extensive wetlands, though heavily impacted by development and pollution, support a wide array of bird and other wildlife species. Persistent contaminants may pose threats to birds in these habitats, affecting reproduction, egg hatchability, nestling survival, and neurobehavioral development. Metals of concern in the Meadowlands include arsenic, cadmium, chromium, lead, and mercury. These metals were analyzed in eggs, feathers, muscle, and liver of Canada geese (Branta canadensis) breeding in four wetland sites. We sampled geese collected during control culling (n=26) and collected eggs from goose nests (n=34). Levels of arsenic were below the minimum quantification level (MQL) in most samples, and cadmium and mercury were low in all tissues sampled. Chromium levels were high in feather samples. Mercury levels in eggs of Canada geese, an almost exclusively herbivorous species, were lower (mean ±SE 4.29±0.30 μg/g wet weight) than in eggs of omnivorous mallards (Anas platyrhynchos), and insectivorous red-winged blackbirds (Agelaius phoeniceus) and marsh wrens (Cistothorus palustris) from the Meadowlands, consistent with trophic level differences. However, lead levels were higher in the goose eggs (161±36.7 ng/g) than in the other species. Geese also had higher levels of lead in feathers (1910±386 ng/g) than those seen in Meadowlands passerines. By contrast, muscle and liver lead levels were within the range reported in waterfowl elsewhere, possibly a reflection of metal sequestration in eggs and feathers. Elevated lead levels may be the result of sediment ingestion or ingestion of lead shot and sinkers. Finally, lead levels in goose liver (249±44.7 ng/g) and eggs (161±36.7 ng/g) may pose a risk if consumed

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

Gosling et al. have presented a very nice set of statistical data on solar wind driver gases (CMEs), interplanetary shocks, solar wind velocities, magnetic field magnitudes and B z values, and geomagnetic activity (Kp). The statistics are quite nice and similar to our own. The authors have no questions or comments concerning these. The authors note that Gosling et al. have one conclusion that is substantially different than prior work, however. In the last sentence of their abstract, they state, open-quotes The initial speed of a CME close to the Sun appears to be the most crucial factor in determining if an earthward directed event will be effective in exciting a large geomagnetic disturbance.close quotes This is an unusual claim and goes quite contrary to prior perceptions of the interplanetary cause of magnetic storms, big and small. If this point is indeed correct it will be a big revelation to magnetospheric researchers. However, in looking at their paper in detail, the authors feel the statistical data that they presented do not support this claim. In this comment the authors will try to help clarify this issue and attempt to bring the Gosling et al. statistics and prior results into accord. 28 refs

Full Text Available Goose parvovirus (GPV remains as a worldwide problem in goose industry. For this reason, it is necessary to develop a new diagnostic approach that is easier and faster than conventional tests. A rapid immunochromatographic assay based on antibody colloidal gold nanoparticles specific to GPV was developed for the detection of GPV in goose allantoic fluid and supernatant of tissue homogenate. The monoclonal antibodies (Mab was produced by immunizing the BALB/c mice with purified GPV suspension, and the polyclonal antibody (pAb was produced by immunizing the rabbits with recombinant VP3 protein. The colloidal gold was prepared by the reduction of gold salt with sodium citrate coupled with Mab against GPV. The optimal concentrations of the coating antibody and capture antibody were determined to be 1.6 mg/ml and 9 μg/ml. With visual observation, the lower limit was found to be around 1.2 μg/ml. Common diseases of goose were tested to evaluate the specificity of the immune colloidal gold (ICG strip, and no cross-reaction was observed. The clinical detection was examined by carrying out the ICG strip test with 92 samples and comparing the results of these tests with those obtained via agar diffusion test and polymerase chain reaction (PCR test. Therefore, the ICG strip test was a sufficiently sensitive and accurate detection method for a rapid screening of GPV.

Mitochondrial D-loop sequence of domesticated waterfowl in Central Java: goose and muscovy duck
Susanti, R.; Iswari, R. S.
2018-03-01
This study aims to determine the genetic characterization of domesticated waterfowl (goose and Muscovy duck) in Central Java based on a D-loop mtDNA gene. The D-loop gene was amplified using PCR technique by specific primer and sequenced using dideoxy termination method. Multiple alignments of D-loop gene obtained were 710 nucleotides at position 74 to 783 at the 5’ end (for goose) and 712 nucleotides at position 48 to 759 at the 5’ end (for Muscovy duck). The results of the polymorphism analysis on D-loop sequences of muscovy duck produced 3 haplotypes. In the D-loop gene of goose does not show polymorphism, with substitution at G117A. Phylogenetic trees reconstructions of goose and Muscovy duck, which was collected during this research compared with another species from Anser, Chairina and Anas was generated 2 forms of clusters. The first group consists of all kind of Muscovy duck together with Chairina moschata and Anas, while the second group consists of all geese and Anser cygnoides the other. The determination of Muscovy duck and geese identity can be distinguished from the genetic marker information. Based on the phylogenetic analysis, it can be concluded that the Muscovy duck is closely related to Chairina moschata, while geese is closely related to Anser cygnoides.

Global prevalence of non-alcoholic fatty liver disease (NAFLD) constitutes a threat to human health. Goose is a unique model of NAFLD for discovering therapeutic targets as its liver can develop severe steatosis without overt injury. Fatty acid desaturase (Fads) is a potential therapeutic target as Fads expression and mutations are associated with liver fat. Here, we hypothesized that Fads was promoted to provide a protection for goose fatty liver. To test this, goose Fads1 and Fads2 were sequenced. Fads1/2/6 expression was determined in goose liver and primary hepatocytes by quantitative PCR. Liver fatty acid composition was also analyzed by gas chromatography. Data indicated that hepatic Fads1/2/6 expression was gradually increased with the time of overfeeding. In contrast, trans-C18:1n9 fatty acid (Fads inhibitor) was reduced. However, enhanced Fads capacity for long-chain polyunsaturated fatty acid (LC-PUFA) synthesis was not sufficient to compensate for the depleted LC-PUFAs in goose fatty liver. Moreover, cell studies showed that Fads1/2/6 expression was regulated by fatty liver-associated factors. Together, these findings suggest Fads1/2 as protective components are promoted to meet instant need for LC-PUFAs in goose fatty liver, and we propose this is required for severe hepatic steatosis without liver injury.

Inundation, sedimentation, and subsidence creates goose habitat along the Arctic coast of Alaska
Tape, Ken D.; Flint, Paul L.; Meixell, Brandt W.; Gaglioti, Benjamin V.
2013-01-01
The Arctic Coastal Plain of Alaska is characterized by thermokarst lakes and drained lake basins, and the rate of coastal erosion has increased during the last half-century. Portions of the coast are sea level for kilometers inland, and are underlain by ice-rich permafrost. Increased storm surges or terrestrial subsidence would therefore expand the area subject to marine inundation. Since 1976, the distribution of molting Black Brant (Branta bernicla nigricans) on the Arctic Coastal Plain has shifted from inland freshwater lakes to coastal marshes, such as those occupying the Smith River and Garry Creek estuaries. We hypothesized that the movement of geese from inland lakes was caused by an expansion of high quality goose forage in coastal areas. We examined the recent history of vegetation and geomorphological changes in coastal goose habitat by combining analysis of time series imagery between 1948 and 2010 with soil stratigraphy dated using bomb-curve radiocarbon. Time series of vertical imagery and in situ verification showed permafrost thaw and subsidence of polygonal tundra. Soil stratigraphy and dating within coastal estuaries showed that non-saline vegetation communities were buried by multiple sedimentation episodes between 1948 and 1995, accompanying a shift toward salt-tolerant vegetation. This sedimentation allowed high quality goose forage plants to expand, thus facilitating the shift in goose distribution. Declining sea ice and the increasing rate of terrestrial inundation, sedimentation, and subsidence in coastal estuaries of Alaska may portend a 'tipping point' whereby inland areas would be transformed into salt marshes.

2012-01-01
Full Text Available Purpose: Proximal migration of the ureteric double J stent is a rare but known complication. We describe three cases where a minimally invasive technique for retrieval of displaced double J stents using Amplatz™ goose-neck snare was successful. Materials and Methods: A retrospective review of patients with displaced double J stent was carried out, in whom cystoscopy guided retrieval of double J stent was attempted with the help of Amplatz goose-neck snare under radiological control. Results: All three patients were under the age of 3 years. Two patients had migrated double J stent following pyeloplasty and in one patient the double J stent was displaced during a retrograde insertion of double J stent. In all cases, retrieval of displaced double J stent was successfully achieved using Amplatz goose-neck snare. There were no postoperative complications. Conclusion: Our method of retrieval of stent from renal pelvis is simple, safe and minimally invasive. This technique is a useful and safe alternative option for retrieval of proximally migrated double J stents in children.

Plasma glucose, free fatty acid and uric acid levels were measured in lead-poisoned Canada geese (Branta canadensis). Although plasma glucose levels were only slightly elevated, uric acid was significantly higher and free fatty acids were significantly lower. Altered plasma levels were attributed to increased protein catabolism and renal dysfunction. Plasma level of growth hormone and prolactin was assessed by radioimmunoassay. Growth hormone remained unchanged while prolactin was unusually high. The increased prolactin levels may reflect an effort to stabilize free fatty acids. 30 references, 1 figure, 2 tables

We analyzed viable seed content in dung of the four numerically most important terrestrial vertebrates in Northeast Greenland - muskox (Ovibos...... moschatus), barnacle goose (Branta leucopsis), Arctic fox (Alopex lagopus) and Arctic hare (Lepus arcticus). High numbers of plant propagules were found in the dung of muskox and barnacle goose. Seeds of many plant species were found in the faeces of one vertebrate species only. Propagule composition...... in barnacle goose droppings was relatively uniform over samples, with a high abundance of the nutritious bulbils of Polygonum viviparum (Bistorta vivipara), suggesting that geese have a narrow habitat preference and feed selectively. Propagule composition in muskox dung was diverse and heterogeneous among...

Goose parvovirus (GPV), a small non-enveloped ssDNA virus, can cause Derzsy's disease, and three capsid proteins of VP1, VP2, and VP3 are encoded by an overlapping nucleotide sequence. However, little is known on whether recombinant viral proteins (VPs) could spontaneously assemble into virus-like particles (VLPs) in insect cells and whether these VLPs could retain their immunoreactivity and immunogenicity in susceptible geese. To address these issues, genes for these GPV VPs were amplified by PCR, and the recombinant VPs proteins were expressed in insect cells using a baculovirus expression system for the characterization of their structures, immunoreactivity, and immunogenicity. The rVP1, rVP2, and rVP3 expressed in Sf9 cells were detected by anti-GPV sera, anti-VP3 sera, and anti-His antibodies, respectively. Electron microscopy revealed that these rVPs spontaneously assembled into VLPs in insect cells, similar to that of the purified wild-type GPV virions. In addition, vaccination with individual types of VLPs, particularly with the rVP2-VLPs, induced higher titers of antibodies and neutralized different strains of GPVs in primary goose and duck embryo fibroblast cells in vitro. These data indicated that these VLPs retained immunoreactivity and had strong immunogenicity in susceptible geese. Therefore, our findings may provide a framework for development of new vaccines for the prevention of Derzsy's disease and vehicles for the delivery of drugs. Copyright © 2011 Elsevier Inc.

Winter fidelity and apparent survival of lesser snow goose populations in the Pacific flyway
Williams, C.K.; Samuel, M.D.; Baranyuk, Vasily V.; Cooch, E.G.; Kraege, Donald K.
2008-01-01
The Beringia region of the Arctic contains 2 colonies of lesser snow geese (Chen caerulescens caerulescens) breeding on Wrangel Island, Russia, and Banks Island, Canada, and wintering in North America. The Wrangel Island population is composed of 2 subpopulations from a sympatric breeding colony but separate wintering areas, whereas the Banks Island population shares a sympatric wintering area in California, USA, with one of the Wrangel Island subpopulations. The Wrangel Island colony represents the last major snow goose population in Russia and has fluctuated considerably since 1970, whereas the Banks Island population has more than doubled. The reasons for these changes are unclear, but hypotheses include independent population demographics (survival and recruitment) and immigration and emigration among breeding or wintering populations. These demographic and movement patterns have important ecological and management implications for understanding goose population structure, harvest of admixed populations, and gene flow among populations with separate breeding or wintering areas. From 1993 to 1996, we neckbanded molting birds at their breeding colonies and resighted birds on the wintering grounds. We used multistate mark-recapture models to evaluate apparent survival rates, resighting rates, winter fidelity, and potential exchange among these populations. We also compared the utility of face stain in Wrangel Island breeding geese as a predictor of their wintering area. Our results showed similar apparent survival rates between subpopulations of Wrangel Island snow geese and lower apparent survival, but higher emigration, for the Banks Island birds. Males had lower apparent survival than females, most likely due to differences in neckband loss. Transition between wintering areas was low (exchange between the Banks and northern Wrangel Island populations. Face staining was an unreliable indicator of wintering area. Our findings suggest that northern and southern

Short beak and dwarfism syndrome of mule duck is caused by a distinct lineage of goose parvovirus.

2009-04-01
From the early 1970s to the present, numerous cases of short beak and dwarfism syndrome (SBDS) have been reported in mule ducks from France. The animals showed strong growth retardation with smaller beak and tarsus. It was suggested that the syndrome was caused by goose parvovirus on the basis of serological investigation, but the causative agent has not been isolated and the disease has not so far been reproduced by experimental infection. The aim of the present study was to characterize the virus strains isolated from field cases of SBDS, and to reproduce the disease experimentally. Phylogenetic analysis proved that the parvovirus isolates obtained from SBDS of mule duck belonged to a distinct lineage of goose parvovirus-related group of waterfowl parvoviruses. The authors carried out experimental infections of 1-day-old, 2-week-old and 3-week-old mule ducks by the oral route with three different parvovirus strains: strain D17/99 of goose parvovirus from Derzsy's disease, strain FM of Muscovy duck parvovirus from the parvovirus disease of Muscovy ducks, and strain D176/02 isolated from SBDS of mule duck. The symptoms of SBDS of the mule duck could only be reproduced with the mule duck isolate (strain D176/02) following 1-day-old inoculation. Infection with a genetically different strain of goose parvovirus isolated from classical Derzsy's disease (D17/99) or with the Muscovy duck parvovirus strain (FM) did not cause any clinical symptoms or pathological lesions in mule ducks.

The SYG61v is an attenuated goose parvovirus (GPV) that has been used as a vaccine strain in China. The genome of SYG61v was sequenced to attempt to identify the genetic basis for the attenuation of this strain. The entire genome consists of 5102 nucleotides (nts), with four nt deletions compared to that of virulent strain B. The inverted terminal repeats (ITR) are 442 nts in length, of which 360 nts form a stem region, and 43 nts constitute the bubble region. Although mutations were observed throughout the ITR, no mismatch was found in the stem. Alignment with other pathogenic GPV strains (B, 82-0321, 06-0329, and YZ99-5) indicated that there are 10 and 11 amino acid mutations in the Rep1 and VP1 proteins of SYG61v, respectively. The complete genome of SYG61v was cloned into the pBluescript II vector and an infectious plasmid pSYG61v was generated. Infectious progeny virus was successfully rescued through transfection of the plasmid pSYG61v in embryonated goose eggs and yielded viral titers similar to its parental virus, as evaluated by ELD50.

However, little is known on whether recombinant viral proteins (VPs) could spontaneously assemble into virus-like particles (VLPs) in insect cells and whether these VLPs could retain their immunoreactivity and immunogenicity in susceptible geese. To address these issues, genes for these GPV VPs were amplified by PCR, and the recombinant VPs proteins were expressed in insect cells using a baculovirus expression system for the characterization of their structures, immunoreactivity, and immunogenicity. The rVP1, rVP2, and rVP3 expressed in Sf9 cells were detected by anti-GPV sera, anti-VP3 sera, and anti-His antibodies, respectively. Electron microscopy revealed that these rVPs spontaneously assembled into VLPs in insect cells, similar to that of the purified wild-type GPV virions. In addition, vaccination with individual types of VLPs, particularly with the rVP2-VLPs, induced higher titers of antibodies and neutralized different strains of GPVs in primary goose and duck embryo fibroblast cells in vitro. These data indicated that these VLPs retained immunoreactivity and had strong immunogenicity in susceptible geese. Therefore, our findings may provide a framework for development of new vaccines for the prevention of Derzsy's disease and vehicles for the delivery of drugs.

Geese described are non-migratory, free-flying Todd's Canada geese (Branta canadensis interior). The genealogy of 261 of these geese was traced by archival research and three years of field observations. Nest locations and densities, preferences for various types of artificial nest structures, clutch sizes, hatching success, brood survival to flight stage, and food habits were recorded. Resul ts indicate geese may:,pair as yearlings, but these bonds may be broken and re-formed before breeding. Pair bonding generally resulted in geese of similar ages remaining together until the death of one partner, although re-pairing, polygamy, and pairing between broodmates also occurred. The dominance hierarchy of related birds strongly influenced the position of 'outsiders' pairing with indigenous females. Dominant status passed not only from male to male, but, upon the death of the dominant male, in at least one instance, the surviving female retained dominant status. Gang broods were composed of progeny of the rearing pair, plus goslings relinquished by female offspring or siblings of the rearing pair. Among indentifiable geese, gang broods were reared by the dominant pair on each impoundment. Geese retained their family integrity both in flight and during the post-molt dispersion. Female and males paired with local females, nested in their natal areas. No significant relationship (P family. Collars, legbands, and telemetry were initially used to distinguish conspecifics. It was subsequently discovered that individual geese could be recognized by cheek-patch patterns, unusual plumage, or mannerisms. It is suggested that cheek-patch similarities in related Canada geese might be used to trace gene flow within flocks, and may be used for individual recognition by other Canada geese.

A recent epizootic outbreak, in China, of duck beak atrophy and dwarfism syndrome (BADS) was investigated using electron microscopic, genetic, and virological studies, which identified a parvovirus with a greater similarity to goose parvovirus (GPV) (97% protein homology) than to Muscovy duck parvovirus (MDPV) (90% protein homology). The new virus, provisionally designated GPV-QH15, was found to be antigenically more closely related to GPV than to MDPV in a virus neutralization assay. These findings were further supported by phylogenetic analysis showing that GPV-QH15 evolved from goose lineage parvoviruses, rather than from Muscovy duck- or other duck species-related parvoviruses. In all, two genetic lineages (GPV I and GPV II) were identified from the GPV samples analyzed, and GPV-QH15 was found to be closely clustered with two known goose-origin parvoviruses (GPVa2006 and GPV1995), together forming a distinctive GPV IIa sublineage. Finally, structural modeling revealed that GPV-QH15 and the closely related viruses GPVa2006 and GPV1995 possessed identical clusters of receptor-interacting amino acid residues in the VP2 protein, a major determinant of viral receptor binding and host specificity. Significantly, these three viruses differed from MDPVs and other GPVs at these positions. Taken together, these results suggest that GPV-QH15 represents a new variant of goose-origin parvovirus that currently circulates in ducklings and causes BADS, a syndrome reported previously in Europe. This new finding highlights the need for future surveillance of GPV-QH15 in poultry in order to gain a better understanding of both the evolution and the biology of this emerging parvovirus.

We report a novel goose parvovirus (MDGPV/PT) isolated from an affected Muscovy duck in Fujian Province, China. In this study, the NS1 sequence analyses indicated a close genetic relationship between MDGPV/PT and Muscovy duck parvovirus (MDPV) strains, although MDGPV/DY, which was isolated from a Muscovy duck in 2006 in Sichuan Province, could be divided into GPV-related groups. Phylogenetic analysis showed that except for differences in the NS1 gene, MDGPV strains PT and DY are closely related to a parvovirus that infects domestic waterfowls. This is the first demonstration of recombination between goose and Muscovy duck parvoviruses in nature, and MDGPV/PT might have led to the generation of a novel waterfowl parvovirus strain circulating in Muscovy duck flocks in China.

Juvenile greylag geese (Anser anser discriminate between individual siblings.
Directory of Open Access Journals (Sweden)
Isabella B R Scheiber
Full Text Available Social species that maintain individualised relationships with certain others despite continuous changes in age, reproductive status and dominance rank between group members ought to be capable of individual recognition. Tests of "true" individual recognition, where an individual recognises unique features of another, are rare, however. Often kinship and/or familiarity suffice to explain dyadic interactions. The complex relationships within a greylag goose flock suggest that they should be able to recognise individuals irrespective of familiarity or kinship. We tested whether six-week-old hand-raised greylags can discriminate between two of their siblings. We developed a new experimental protocol, in which geese were trained to associate social siblings with geometrical symbols. Subsequently, focals were presented with two geometrical symbols in the presence of a sibling associated with one of the symbols. Significant choice of the geometrical symbol associated with the target present indicated that focals were able to distinguish between individual targets. Greylag goslings successfully learned this association-discrimination task, regardless of genetic relatedness or sex of the sibling targets. Social relationships within a goose flock thus may indeed be based on recognition of unique features of individual conspecifics.

Full Text Available Seafood plays an important role in the socioeconomic, gastronomy and cultural heritage of Portuguese coastal communities. In the Iberian Peninsula, the goose barnacle Pollicipes pollicipes is the intertidal biological resource most heavily exploited by man, resulting on overexploitation of stocks. In the MPA of BNR P.pollicipes harvesting is however strictly regulated, making it a good example of marine resources management. Analytical methods able to identify the origin of goose barnacle would be an important tool to help the management of the trade. For such purpose, we investigated whether P. pollicipes have site-specific differences based on its elemental microchemistry (EM, fatty acid profile (FA and capitulum shape (CS. The analysis was performed on specimens collected from 3 sites in the BNR and 7 along a 300 km stretch of the Portuguese coast. For each individual we analysed the largest lateral shell for EM using ICP-MS, the FA content of the muscle using GC-FID, and the CS using geometric morphometrics. Discriminant function analyses (DFA for both EM and FA separately provided a high reclassification success (77.6% and 99% respectively, of cross-validated cases correctly classified, while for EM combined with FA allowed for a 100% reclassification success. DFA analysis based only on CS, revealed a low classification success (29.6%. These results show that EM and FA signatures can be a powerful tool to infer goose barnacles origin. Such “fingerprinting” approach can be used to track and identify goose barnacles origin, helping in establishing an origin certificate and increasing the potential value of biological resources from Portuguese MPAs.

Full Text Available The aim of our study was to evaluate the effect of overfeeding on mRNA expression levels of genes involved in lipogenesis, in order to understand the mechanism of hepatic stea - tosis in the goose. Using Landes geese (Anser anser and Sichuan White geese (Anser cygnoides as experimental animals, we quantified the mRNA expression of lipogenic genes, acetyl-CoA carboxylase-α (ACCα and fatty acid synthase (FAS, and of two transcription factors, sterol regulatory element-binding proteins- 1 (SREBP-1 and carbohydrate responsive element-binding protein (ChREBP by real-time polymerase chain reaction (RTPCR, and measured the lipid and triglyceride (TG content in the liver and the plasma level of glucose, insulin and TG. Our results indicated that compared to the control group, the overfeeding induced an increase of the lipid and TG content in the liver and also of the plasma insulin and TG concentration in both breeds. However, the plasma glucose level decreased after overfeeding in the Sichuan White goose, and there was no evident change in the Landes goose. Lastly, the mRNA expression of ACCα, FAS, SREBP-1 and ChREBP in the overfed group was lower than in the control group in both breeds. We concluded that the lipogenesis pathway plays a role in overfeeding- induced hepatic steatosis and that the decreased mRNA level of related genes may be the indicator of hepatic steatosis.

Synaptotagmin-1 (Syt1) is an abundant, evolutionarily conserved integral membrane protein that plays essential roles in neurotransmitter release and hormone secretion. Neurotransmitters secreted by hypothalamic neurons can alter GnRH (gonadotropin-releasing hormones) neuronal activity by binding to and activating specific membrane receptors in pituitary cells and, in turn, control the release of gonadotropin hormones from the pituitary gland. To reveal the influence of Syt1 on the process of goose egg-laying, we cloned and characterized the cDNA of goose Syt1 originating from hypothalamus and pituitary tissues of Huoyan goose and investigated the mRNA expression profiles during different stages of the egg-laying cycle. Hypothalamus and pituitary tissues were obtained from 36 Huoyan geese in the pre-laying period, early laying period, peak-laying period, and ceased period. The cDNA sequences of goose Syt1 were cloned and characterized from Huoyan goose tissues using 5'-RACE and 3'-RACE methods. Multiple alignments and phylogenetic analyses of the deduced Syt1 amino acid sequence were conducted using bioinformatics tools. The expression profiles of the Syt1 mRNA in the hypothalamus and pituitary during pre-laying, early laying, peak-laying and ceased period were examined using real-time PCR (qRT-PCR). The cDNA of Syt1 consisted of a 274 bp 5' UTR, a 1266 bp open reading frame (ORF) encoding 421 amino acids, and a 519 bp 3' UTR. The deduced amino acid sequence of goose Syt1 is highly conserved with the sequence from other species, especially with birds (more than 98%), and contains two protein kinase C2 conserved regions (C2 domain) from amino acids residue 157 to 259 and 288 to 402. The results of qRT-PCR demonstrated that the expression of Syt1 mRNA increased from the pre-laying period to the peak-laying period, reached its peak in the peak-laying period, and then decreased in the ceased period. To the best of our knowledge, this study is the first to obtain full

The objective of the work was to investigate the color and lipid oxidation changes of goose breast meat packaged in vacuum and modified atmosphere (MA) conditions consisting of 80% O2, 20% CO2, and stored in refrigerated conditions at 4°C. Color stability was monitored by determining total heme pigments concentration; relative concentration of myoglobin, oxymyoglobin, and metmyoglobin; parameters of color L*, a*, b*, and sensory evaluation of the surface color. Lipid stability was measured by determining thiobarbituric acid reactive substances (TBARS). The samples were examined in 24 h after slaughter (unpacked muscles) and on d 4, 7, 9, 11 of storage (muscles packed in vacuum and in MA). Through the time of storage, samples packed in MA had higher TBARS values in comparison to the meat packed in vacuum. For samples packed in two types of atmospheres, the total pigments concentration decreased gradually within 11 d of storage. It was observed that relative metmyoglobin concentration increased whereas relative oxymyoglobin concentration decreased in total heme pigments in the MA stored muscle. The relative concentration of all three myoglobin forms sample packed in vacuum remained unchanged. The color parameters (L*, a*, b*) did not change for 11 d of storage for the vacuum packed meat. The value of the color parameter a* decreased and the value of the color parameters L* and b* increased in the samples packaged in MA. The data prove that if you store goose meat in MA (consisting of 80% O2, 20% CO2) or vacuum, the unchanged surface color is preserved for 9 and 11 day, respectively.Vacuum appears to be a better method as regards the maintaining of lipid stability in goose meat. © 2016 Poultry Science Association Inc.

Iron deficiency anemia (IDA) is the most common nutritional deficiency worldwide. This deficiency could be solved by preparing stable, edible, and absorbable iron food ingredients using environmentally friendly methods. This study investigated enzymatic hydrolysis and microencapsulation process of goose blood. The physicochemical properties, stabilities of the microencapsulated goose blood hydrolysate (MGBH) and a supplement for rats with IDA were also evaluated. The results showed that the synergetic hydrolytic action of neutrase and alkaline protease significantly increased the heme-releasing efficiency. The heme was then microencapsulated using sodium caseinate, maltodextrin and carboxymethyl cellulose (CMC) as the edible wall material, and the encapsulation efficiency of the product reached 98.64%. Meanwhile, favorable thermal, storage and light stabilities were observed for the microencapsulation. It was found that MGBH can significantly improve the body weight and hematological parameters of IDA Wistar rat. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Circoviruses are circular single-stranded DNA (ssDNA viruses that infect a variety of animals, both domestic and wild. Circovirus infection in birds is associated with immunosuppression and this in turn predisposes the infected animals to secondary infections that can lead to mortality. Farmed geese (Anser anser in many parts of the world are infected with circoviruses. The majority of the current genomic information for goose circoviruses (GoCVs (n = 40 are from birds sampled in China and Taiwan, and only two genome sequences are available from Europe (Germany and Poland. In this study, we sampled 23 wild and 19 domestic geese from the Gopło Lake area in Poland. We determined the genomes of GoCV from 21 geese; 14 domestic Greylag geese (Anser anser, three wild Greylag geese (A. anser, three bean geese (A. fabalis, and one white fronted goose (A. albifrons. These genomes share 83–95% nucleotide pairwise identities with previously identified GoCV genomes, most are recombinants with exchanged fragment sizes up to 50% of the genome. Higher diversity levels can be seen within the genomes from domestic geese compared with those from wild geese. In the GoCV capsid protein (cp and replication associated protein (rep gene sequences we found that episodic positive selection appears to largely mirror those of beak and feather disease virus and pigeon circovirus. Analysis of the secondary structure of the ssDNA genome revealed a conserved stem-loop structure with the G-C rich stem having a high degree of negative selection on these nucleotides.

Many refrigerators using CFC as a refrigerant are seen as the cause of the depletion of ozone. Hence, thermoacoustic was chosen as an alternative refrigerator that safe for environment. There are many variable that influenced the optimization of thermoacoustic design. One of them is thermal conductivity of material of stack. The Stack material must have a low thermal conductivity. In this research we used organic stack made of stem of goose down. It has superior thermal insulating. It means that they have the lowest thermal conductivity. The system uses no refrigerant or compressor, and the only mechanical moving part is the loudspeaker connected to a signal generator that produces the acoustic. The working fluid is air and the material of resonator is stainless steel. A series test on the laboratory found that there is a decrease of 5°C in temperature for about 2 minutes.

The Great Basin Canada goose in southcentral Washington: A 40-year nesting history
International Nuclear Information System (INIS)
Fitzner, R.E.; Rickard, W.H.; Eberhardt, L.E.; Gray, R.H.
1991-04-01
Overall, the nesting population of Great Basin Canada geese (Branta canadensis moffitti) on the Hanford Site in southcentral Washington State is doing well and appears to be increasing. The average annual total nests for the period 1981 through 1990 was 215 nests, which is slightly above the average reported for the period 1950 through 1970. The nesting population has shifted its nucleus from upriver islands (1--10) to the lower river islands (11--20) with over 70% of the present-day nesting occurring on Islands 17, 18, 19, 20. The annual percent-successful nests from 1981 through 1990 was 80%. This is above the 71% reported for 1950 to 1970, but is below the 82% reported for 1971 to 1980. Average annual clutch size for 1981 to 1990 was 6.05, which is above the 1971-to-1980 average of 5.6 and the 1950-to-70 average of 5.5. Next desertions for 1981 to 1990 averaged 8%. This rate is well below the 14% reported for 1950 to 1970. Predators were responsible for an annual predation rate of 9% from 1981 to 1990. This is below the 1950-to-1970 annual average predation rate of 14%. Flooding losses to nests were low during the 1980s, except for 1989 and 1990 when 6% and 9% of the total nests, respectively, were destroyed by flooding. 9 refs., 4 figs., 1 tab

On August 14, 2003, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the Beaver Lake property, an acquisition completed by the Kalispel Tribe of Indians in November 2002. Evaluation species and appropriate models include bald eagle, black-capped chickadee, Canada goose, mallard, muskrat, yellow warbler, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The Beaver Lake Project provides a total of 232.26 Habitat Units (HUs) for the species evaluated. Conifer forest habitat provides 136.58 HUs for bald eagle, black-capped chickadee, mallard, and white-tailed deer. Forested wetland habitat provides 20.02 HUs for bald eagle, black-caped chickadee, mallard, and white-tailed deer. Scrub-shrub wetland habitat provides 7.67 HUs for mallard, yellow warbler, and white-tailed deer. Grassland meadow provides 22.69 HUs for Canada goose and mallard. Emergent wetlands provide 35.04 HUs for Canada goose, mallard, and muskrat. Open water provided 10.26 HUs for Canada goose, mallard, and muskrat. The objective of using HEP at the Beaver Lake Project and other protected properties is to document the quality and quantity of available habitat for selected wildlife species. In this way, HEP provides information on the relative value of the same area at future points in time so that the effect of management activities on wildlife habitat can be quantified. When combined with other tools, the baseline HEP will be used to determine the most effective on-site management, restoration, and enhancement actions to increase habitat suitability for targeted species. The same process will be replicated every five years to quantitatively evaluate the effectiveness of management strategies in improving and maintaining habitat conditions while providing additional crediting to BPA for enhanced habitat values.

Duck short beak and dwarfism syndrome (SBDS) is an emerging infectious disease caused by a novel goose parvovirus-related virus (NGPV) in China. Until now, it remains uncertain whether the Cherry Valley ducks and mule ducks with SBDS are co-infected with classical goose parvovirus (GPV) and NGPV. In this study, a duplex semi-nested PCR assay with high specificity and sensitivity was developed for detection of the two viruses. Using the duplex PCR assay, NGPV was tested positive in all the 15 duck flocks with SBDS, whereas classical GPV was not detected in all the 133 sick and dead ducks collected from East China. A total of 87 (91.58%) Cherry Valley ducks aged from 5 to 18days and 35 (92.11%) mule ducks aged from 17 to 25days were detected positive for NGPV. In the NGPV-positive ducks, the virus detection rates were 81.97% to 8.20% in heart, liver, spleen, lung, kidney, pancreas, bile, thymus, bursa of Fabricius, and brain. The results indicated that NGPV was prevalent in the duck flocks of East China, whereas classical GPV was not detected in Cherry Valley ducks and mule ducks with SBDS. NGPV has extensive tissue tropism in Cherry Valley duck and mule duck, which could invade both the central and peripheral immune organs and break through the blood-brain barrier of ducks.

Muscovy duck parvovirus (MDPV) is the etiological agent of Muscovy duckling parvoviral disease, which is characterized by diarrhea, locomotive dysfunction, stunting, and death in young ducklings, and causes substantial economic losses in the Muscovy duck industry worldwide. FZ91-30 is an attenuated vaccine strain that is safe and immunogenic to ducklings, but the genomic information and molecular mechanism underlining the attenuation are not understood. The FZ91-30 strain was propagated in 11-day-old embryonated goose eggs, and viral particles were purified from the pooled allantoic fluid by differential centrifugation and ultracentrifugation. Single-stranded genomic DNA was extracted and annealed to form double-stranded DNA. The dsDNA digested with NcoI resulted two sub-genomic fragments, which were then cloned into the modified plasmid pBluescript II SK, respectively, generating plasmid pBSKNL and pBSKNR. The sub-genomic plasmid clones were sequenced and further combined to construct the plasmid pFZ that contained the entire genome of strain FZ91-30. The complete genome sequences of strain FM and YY and partial genome sequences of other strains were retrieved from GenBank for sequence comparison. The plasmid pFZ containing the entire genome of FZ91-30 was transfected in 11-day-old embryonated goose eggs via the chorioallantoic membranes route to rescue infectious virus. A genetic marker was introduced into the rescued virus to discriminate from its parental virus. The genome of FZ91-30 consists of 5,131 nucleotides and has 98.9 % similarity to the FM strain. The inverted terminal repeats (ITR) are 456 nucleotides in length, 14 nucleotides longer than that of Goose parvovirus (GPV). The exterior 415 nucleotides of the ITR form a hairpin structure, and the interior 41 nucleotides constitute the D sequence, a reverse complement of the D' sequence at the 3' ITR.

Expression of goose parvovirus whole VP3 protein and its epitopes in Escherichia coli cells.
Tarasiuk, K; Woźniakowski, G; Holec-Gąsior, L
2015-01-01
The aim of this study was the expression of goose parvovirus capsid protein (VP3) and its epitopes in Escherichia coli cells. Expression of the whole VP3 protein provided an insufficient amount of protein. In contrast, the expression of two VP3 epitopes (VP3ep4, VP3ep6) in E. coli, resulted in very high expression levels. This may suggest that smaller parts of the GPV antigenic determinants are more efficiently expressed than the complete VP3 gene.

Goose parvovirus (GPV) continues to be a threat to goose farms and has significant economic effects on the production of geese. Current commercially available vaccines only rarely prevent GPV infection. In our study, Lactobacillus (L.) plantarum NC8 was selected as a vector to express the VP2 gene of GPV, and recombinant L. plantarum pSIP409-VP2/NC8 was successfully constructed. The molecular weight of the expressed recombinant protein was approximately 70 kDa. Mice were immunized with a 2 × 10 9 colony-forming unit/200 μL dose of the recombinant L. plantarum strain, and the ratios and numbers of CD11c + , CD3 + CD4 + , CD3 + CD8 + , and interferon gamma- and tumor necrosis factor alpha-expressing spleen lymphocytes in the pSIP409-VP2/NC8 group were higher than those in the control groups. In addition, we assessed the capacity of L. plantarum SIP409-VP2/NC8 to induce secretory IgA production. We conclude that administered pSIP409-VP2/NC8 leads to relatively extensive cellular responses. This study provides information on GPV infection and offers a clear framework of options available for GPV control strategies.

Effect of the loading rate on compressive properties of goose eggs.
Nedomová, Š; Kumbár, V; Trnka, J; Buchar, J
2016-03-01
The resistance of goose (Anser anser f. domestica) eggs to damage was determined by measuring the average rupture force, specific deformation and rupture energy during their compression at different compression speeds (0.0167, 0.167, 0.334, 1.67, 6.68 and 13.36 mm/s). Eggs have been loaded between their poles (along X axis) and in the equator plane (Z axis). The greatest amount of force required to break the eggs was required when eggs were loaded along the X axis and the least compression force was required along the Z axis. This effect of the loading orientation can be described in terms of the eggshell contour curvature. The rate sensitivity of the eggshell rupture force is higher than that observed for the Japanese quail's eggs.

Entz, Ray
2005-02-01
On July 6, 2004, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the Priest River property, an acquisition completed by the Kalispel Tribe of Indians in 2001. Evaluation species and appropriate models include bald eagle, black-capped chickadee, Canada goose, mallard, yellow warbler, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The Priest River Project provides a total of 105.41 Habitat Units (HUs) for the species evaluated. Conifer forest habitat provides 26.95 HUs for bald eagle, black-capped chickadee, and white-tailed deer. Grassland habitat provides 23.78 HUs for Canada goose and mallard. Scmb-shrub vegetation provides 54.68 HUs for mallard, yellow warbler, and white-tailed deer.

Baseline research on the toughness of Egyptian goose meat is required. This study therefore investigates the post mortem pH and temperature decline (15 min-4 h 15 min post mortem) in the pectoralis muscle (breast portion) of this gamebird species. It also explores the enzyme activity of the Ca(2+)-dependent protease (calpain system) and the lysosomal cathepsins during the rigor mortis period. No differences were found for any of the variables between genders. The pH decline in the pectoralis muscle occurs quite rapidly (c = -0.806; ultimate pH ∼ 5.86) compared with other species and it is speculated that the high rigor temperature (>20 °C) may contribute to the increased toughness. No calpain I was found in Egyptian goose meat and the µ/m-calpain activity remained constant during the rigor period, while a decrease in calpastatin activity was observed. The cathepsin B, B & L and H activity increased over the rigor period. Further research into the connective tissue content and myofibrillar breakdown during aging is required in order to know if the proteolytic enzymes do in actual fact contribute to tenderisation. © 2015 Society of Chemical Industry.

Spatial organization of the gastrointestinal microbiota in urban Canada geese
Drovetski, Sergei V.; O'Mahoney, Michael; Ransome, Emma J.; Matterson, Kenan O.; Lim, Haw Chuan; Chesser, Terry; Graves, Gary R.
2018-01-01
Recent reviews identified the reliance on fecal or cloacal samples as a significant limitation hindering our understanding of the avian gastrointestinal (gut) microbiota and its function. We investigated the microbiota of the esophagus, duodenum, cecum, and colon of a wild urban population of Canada goose (Branta canadensis). From a population sample of 30 individuals, we sequenced the V4 region of the 16S SSU rRNA on an Illumina MiSeq and obtained 8,628,751 sequences with a median of 76,529 per sample. These sequences were assigned to 420 bacterial OTUs and a single archaeon. Firmicutes, Proteobacteria, and Bacteroidetes accounted for 90% of all sequences. Microbiotas from the four gut regions differed significantly in their richness, composition, and variability among individuals. Microbial communities of the esophagus were the most distinctive whereas those of the colon were the least distinctive, reflecting the physical downstream mixing of regional microbiotas. The downstream mixing of regional microbiotas was also responsible for the majority of observed co-occurrence patterns among microbial families. Our results indicate that fecal and cloacal samples inadequately represent the complex patterns of richness, composition, and variability of the gut microbiota and obscure patterns of co-occurrence of microbial lineages.

Choices in ecological research and management are the result of balancing multiple, often competing, objectives. Multi-objective optimization (MOO) is a formal decision-theoretic framework for solving multiple objective problems. MOO is used extensively in other fields including engineering, economics, and operations research. However, its application for solving ecological problems has been sparse, perhaps due to a lack of widespread understanding. Thus, our objective was to provide an accessible primer on MOO, including a review of methods common in other fields, a review of their application in ecology, and a demonstration to an applied resource management problem.A large class of methods for solving MOO problems can be separated into two strategies: modelling preferences pre-optimization (the a priori strategy), or modelling preferences post-optimization (the a posteriori strategy). The a priori strategy requires describing preferences among objectives without knowledge of how preferences affect the resulting decision. In the a posteriori strategy, the decision maker simultaneously considers a set of solutions (the Pareto optimal set) and makes a choice based on the trade-offs observed in the set. We describe several methods for modelling preferences pre-optimization, including: the bounded objective function method, the lexicographic method, and the weighted-sum method. We discuss modelling preferences post-optimization through examination of the Pareto optimal set. We applied each MOO strategy to the natural resource management problem of selecting a population target for cackling goose (Branta hutchinsii minima) abundance. Cackling geese provide food security to Native Alaskan subsistence hunters in the goose's nesting area, but depredate crops on private agricultural fields in wintering areas. We developed objective functions to represent the competing objectives related to the cackling goose population target and identified an optimal solution

Full Text Available The western Palaearctic tundra is a breeding habitat for large populations of European geese. After their arrival in spring, pink-footed geese (Anser brachyrhynchus forage extensively on below-ground plant parts, using a feeding technique called grubbing that has substantial impact on the tundra vegetation. Previous studies have shown a high frequency of grubbing in lowland fen vegetation. In the present study, we examined the occurrence of grubbing in other habitat types on Spitsbergen, in the Arctic archipelago of Svalbard. Goose grubbing was surveyed along 19 altitudinal transects, going from the valley bottom to altitudes dominated by scree. Grubbing was more frequent in the wet habitat type at low altitudes compared to the drier habitat type at higher altitudes. For the dry habitat type, a higher frequency of grubbing was found in study plots with a south-east facing exposure where snowmelt is expected to be early. This suggests that pink-footed geese primarily use dry vegetation types for grubbing when they are snow-free in early spring and the availability of snow-free patches of the preferred wet vegetation types in the lowlands is limited. Dry vegetation types have poorer recovery rates from disturbance than wet ones. Sites with early snowmelt and dry vegetation types may therefore be at greater risk of long-term habitat degradation. We conclude that the high growth rate of the Svalbard-breeding pink-footed goose population suggests that increasing impacts of grubbing can be expected and argue that a responsible monitoring of the effects on the tundra ecosystem is crucial.

Goose-skin Pleura: A Thoracoscopic Finding in a Case of Recurrent Undiagnosed Pleural Effusion.
Al-Halfawy, Ahmed; Light, Richard W
2010-10-01
We present the case of a female patient who presented with undiagnosed pleural effusion. Thoracoscopy was performed and at the beginning of the procedure, the parietal pleura was rather uniformly congested but with a smooth surface. As time passed, the parietal pleura became roughened by bumpy areas of mucosal elevations, which looked soft and watery. This became evident during the biopsy procedure, as the pleura was markedly edematous. The biopsy specimens were nonspecific and the cause of the effusion remained unclear. This phenomenon, which we termed "goose-skin" pleura, showed that the origin of the pleural effusion formed was the parietal pleura, for unknown causes.

Distribution of attenuated goose parvoviruses in Muscovy ducklings.
Takehara, K; Saitoh, M; Kiyono, M; Nakamura, M
1998-03-01
With a polymerase chain reaction (PCR) method, goose parvovirus (GPV) DNA was detected in Muscovy ducklings inoculated with attenuated GPV strains, IH and IHC. Strain IH that had been passed 20 times in Muscovy duck embryos could be detected in ducklings at 2- to 28-days after oral inoculation by PCR, however, a cell culture adapted strain IHC that had been passed 15 times in Muscovy duck embryos and then successively 50 times in Muscovy duck embryo fibroblasts could not be detected by 6 days postinoculation by the oral route, but via intramuscular inoculation the virus was detected from 6 dpi. With both strains Muscovy ducklings produced neutralizing antibodies against GPV, but GPV could be recovered from heart muscles even in birds that had high titer of neutralizing antibody. This means that GPV remains in birds for a long period under the presence of high titer of neutralizing antibody in the serum. Recovery of the virus was consistent with PCR results with one exception in which the bird had a neutralizing antibody titer of more than 100,000. After inoculation of these strains, no clinical signs were detected in ducklings. These results suggest that strains IH and IHC can be candidates for live attenuated vaccine for GPV infection.

Abstract From early `70s till now numerous cases of ?short beak and dwarfism syndrome? have been reported in mule ducks from France. The animals showed strong growth retardation with smaller beak and tarsus. The syndrome was suggested to be caused by goose parvovirus on the basis of serological investigation, but the causative agent has not been isolated and the disease has not been reproduced by experimental infection so far. The aim of the present study was to characterize the vi...

mediated response to the presence of E. clarkei oocysts and endogenous stages was seen in 83.3% of infected adult geese, but only 20% of immature geese showed a macrophage response to the infective stages of this parasite. A massive E. clarkei infection caused the death of one goose collected at Horicon National Wildlife Refuge. Amidostomiasis, epomidiostomiasis, and renal coccidiosis were important pathogenic diseases in the Mississippi Valley Population Canada geese but did not directly cause significant mortality in the population.

Full Text Available Previously we showed that fatty liver formation in overfed geese was accompanied by PI3K-Akt-mTOR pathway activation and changes in plasma glucose concentrations. Here, we show that glucose acts in goose hepatocellular lipid metabolism through the PI3K-Akt-mTOR signaling pathway. We observed that glucose increased lipogenesis, decreased fatty acid oxidation and increased very low density lipoprotein triglyceride (VLDL-TG assembly and secretion. Co-treatment with glucose and inhibitors of the PI3K-Akt-mTOR pathway (LY294002, rapamycin, NVP-BEZ235 decreased the levels of factors involved in lipogenesis and increased the levels of factors involved in fatty acid oxidation and VLDL-TG assembly and secretion. These findings show that inhibition of the PI3K-Akt-mTOR pathway decreased glucose-induced lipogenesis, inhibited the downregulation of fatty acid oxidation by glucose and increased the upregulation of VLDL-TG assembly and secretion by glucose. The results presented herein provide further support for the role of the PI3K-Akt-mTOR pathway in lipid metabolism as we showed that in goose primary hepatocytes, glucose acts through the PI3K-Akt-mTOR-dependent pathway to stimulate lipid deposition by increasing lipogenesis and decreasing fatty acid oxidation and VLDL-TG assembly and secretion.

This research examines the feasibility of analyzing tree cores to detect benzene, toluene, ethylbenzene, and m, p, o-xylene (BTEX) compounds and methyl tertiary-butyl ether (MTBE) in groundwater in eastern Canada subarctic environments, using a former landfill site in the remote community of Happy Valley-Goose Bay, Labrador. Petroleum hydrocarbon contamination at the landfill site is the result of environmentally unsound pre-1990s disposal of households and industrial solid wastes. Tree cores were taken from trembling aspen, black spruce, and white birch and analyzed by headspace-gas chromatography-mass spectrometry. BTEX compounds were detected in tree cores, corroborating known groundwater contamination. A zone of anomalously high concentrations of total BTEX constituents was identified and recommended for monitoring by groundwater wells. Tree cores collected outside the landfill site at a local control area suggest the migration of contaminants off-site. Tree species exhibit different concentrations of BTEX constituents, indicating selective uptake and accumulation. Toluene in wood exhibited the highest concentrations, which may also be due to endogenous production. Meanwhile, MTBE was not found in the tree cores and is considered to be absent in the groundwater. The results demonstrate that tree-core analysis can be useful for detecting anomalous concentrations of petroleum hydrocarbons, such as BTEX compounds, in subarctic sites with shallow unconfined aquifers and permeable soils. This method can therefore aid in the proper management of contamination during landfill operations and after site closures.

Four experiments were conducted to examine the riboflavin, pantothenic acid, nicotinic acid, and choline requirements of young Embden geese fed purified diets. Goslings fed diets deficient in either riboflavin, pantothenic acid, nicotinic acid, or choline grew poorly. Feeding a pantothenic acid-deficient diet resulted in 100% mortality. Goslings fed diets containing 530 mg/kg of choline or less developed perosis. Under the conditions of these experiments it was found that: 1) goslings require no more than 3.84 mg/kg of riboflavin and 31.2 mg/kg of nicotinic acid in the diet for rapid growth and normal development, 2) the pantothenic acid requirement of goslings is no more than 12.6 mg/kg of diet, and 3) a dietary choline level of 1530 mg/kg is adequate for both the prevention of perosis and rapid growth of goslings. The levels of vitamins found to support normal growth and development of goslings appear to be similar to requirements of other species that have been examined.

The lower Flathead System Canada Goose Study was initiated to determine population trends and the effects of water level fluctuations on nest and brood habitat on the southern half of Flathead Lake and the lower Flathead River as a result of the operations of Kerr Dam. This report presents data collected during the 1984 field season as part of an ongoing project. Geese used Pablo, Kicking Horse, Ninepipe Reservoirs heavily during late summer and fall. Use of the river by geese was high during the winter, when the reservoirs were frozen, and during the breeding period. Most breeding geese left the river after broods fledged. Thirteen percent of the artificial tree nest structures on the river were used by nesting geese. Goose nest initiation on the river peaked the last week in March through the first week in April, and hatching peaked the first week in May. Predation was the most significant cause of nest loss on the river, and nest loss by flooding was not observed. Avian predation was the single largest factor contributing to nest loss on the lake. Habitat use was studied in 4 brood areas on the river and 8 brood areas on the lake, and available habitat was assessed for 2 portions of both the lake and the river. Brood habitat use was significantly different from the available habitat in all areas studied. On the lower river, broods used wheat fields, gravel bars, and shrub habitats. On the upper river, coniferous forest and shrub habitats were preferred. On the West Bay of the lake, brood areas consisted primarily of lawns and tall herbaceous habitat, while on the South Bay, marshes dominated the brood areas studied. Water levels on the river and lake affect both accessibility of these areas to brooding geese, and the ecology of the habitats preferred by geese. 43 refs., 24 figs., 31 tabs.

On July 6, 2004, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the Priest River property, an acquisition completed by the Kalispel Tribe of Indians in 2001. Evaluation species and appropriate models include bald eagle, black-capped chickadee, Canada goose, mallard, yellow warbler, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The Priest River Project provides a total of 140.73 Habitat Units (HUs) for the species evaluated. Conifer forest habitat provides 60.05 HUs for bald eagle, black-capped chickadee, and white-tailed deer. Grassland meadow habitat provides 7.39 HUs for Canada goose and mallard. Scrub-shrub vegetation provides 71.13 HUs for mallard, yellow warbler, and white-tailed deer. Open water habitat provides 2.16 HUs for Canada goose and mallard. The objective of using HEP at the Priest River Project and other protected properties is to document the quality and quantity of available habitat for selected wildlife species. In this way, HEP provides information on the relative value of the same area at future points in time so that the effect of management activities on wildlife habitat can be quantified. When combined with other tools, the baseline HEP will be used to determine the most effective on-site management, restoration, and enhancement actions to increase habitat suitability for targeted species. The same process will be replicated every five years to quantitatively evaluate the effectiveness of management strategies in improving and maintaining habitat conditions while providing additional crediting to BPA for enhanced habitat values.

Factors influencing reporting and harvest probabilities in North American geese
Zimmerman, G.S.; Moser, T.J.; Kendall, W.L.; Doherty, P.F.; White, Gary C.; Caswell, D.F.
2009-01-01
We assessed variation in reporting probabilities of standard bands among species, populations, harvest locations, and size classes of North American geese to enable estimation of unbiased harvest probabilities. We included reward (US10,20,30,50, or100) and control (0) banded geese from 16 recognized goose populations of 4 species: Canada (Branta canadensis), cackling (B. hutchinsii), Ross's (Chen rossii), and snow geese (C. caerulescens). We incorporated spatially explicit direct recoveries and live recaptures into a multinomial model to estimate reporting, harvest, and band-retention probabilities. We compared various models for estimating harvest probabilities at country (United States vs. Canada), flyway (5 administrative regions), and harvest area (i.e., flyways divided into northern and southern sections) scales. Mean reporting probability of standard bands was 0.73 (95 CI 0.690.77). Point estimates of reporting probabilities for goose populations or spatial units varied from 0.52 to 0.93, but confidence intervals for individual estimates overlapped and model selection indicated that models with species, population, or spatial effects were less parsimonious than those without these effects. Our estimates were similar to recently reported estimates for mallards (Anas platyrhynchos). We provide current harvest probability estimates for these populations using our direct measures of reporting probability, improving the accuracy of previous estimates obtained from recovery probabilities alone. Goose managers and researchers throughout North America can use our reporting probabilities to correct recovery probabilities estimated from standard banding operations for deriving spatially explicit harvest probabilities.

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

Phylogenetic analysis of Hungarian goose parvovirus isolates and vaccine strains.
Tatár-Kis, Tímea; Mató, Tamás; Markos, Béla; Palya, Vilmos
2004-08-01
Polymerase chain reaction and sequencing were used to analyse goose parvovirus field isolates and vaccine strains. Two fragments of the genome were amplified. Fragment "A" represents a region of VP3 gene, while fragment "B" represents a region upstream of the VP3 gene, encompassing part of the VP1 gene. In the region of fragment "A" the deduced amino acid sequence of the strains was identical, therefore differentiation among strains could be done only at the nucleotide level, which resulted in the formation of three groups: Hungarian, West-European and Asian strains. In the region of fragment "B", separation of groups could be done by both nucleotide and deduced amino acid sequence level. The nucleotide sequences resulted in the same groups as for fragment "A" but with a different clustering pattern among the Hungarian strains. Within the "Hungarian" group most of the recent field isolates fell into one cluster, very closely related or identical to each other, indicating a very slow evolutionary change. The attenuated strains and field isolates from 1979/80 formed a separate cluster. When vaccine strains and field isolates were compared, two specific amino acid differences were found that can be considered as possible markers for vaccinal strains. Sequence analysis of fragment "B" seems to be a suitable method for differentiation of attenuated vaccine strains from virulent strains. Copyright 2004 Houghton Trust Ltd

A Vocal-Based Analytical Method for Goose Behaviour Recognition
Directory of Open Access Journals (Sweden)
Henrik Karstoft
2012-03-01
Full Text Available Since human-wildlife conflicts are increasing, the development of cost-effective methods for reducing damage or conflict levels is important in wildlife management. A wide range of devices to detect and deter animals causing conflict are used for this purpose, although their effectiveness is often highly variable, due to habituation to disruptive or disturbing stimuli. Automated recognition of behaviours could form a critical component of a system capable of altering the disruptive stimuli to avoid this. In this paper we present a novel method to automatically recognise goose behaviour based on vocalisations from flocks of free-living barnacle geese (Branta leucopsis. The geese were observed and recorded in a natural environment, using a shielded shotgun microphone. The classification used Support Vector Machines (SVMs, which had been trained with labeled data. Greenwood Function Cepstral Coefficients (GFCC were used as features for the pattern recognition algorithm, as they can be adjusted to the hearing capabilities of different species. Three behaviours are classified based in this approach, and the method achieves a good recognition of foraging behaviour (86–97% sensitivity, 89–98% precision and a reasonable recognition of flushing (79–86%, 66–80% and landing behaviour(73–91%, 79–92%. The Support Vector Machine has proven to be a robust classifier for this kind of classification, as generality and non-linearcapabilities are important. We conclude that vocalisations can be used to automatically detect behaviour of conflict wildlife species, and as such, may be used as an integrated part of awildlife management system.

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

This report describes a study of dam passage and survival of radio-tagged juvenile salmonids after installation of a temporary spillway weir (TSW) at Little Goose Dam, Washington, in 2009. The purpose of the study was to document fish passage and survival when the dam was operated with the TSW in place. Spillway weirs are one of several methods used to improve downstream passage of juvenile salmonids. Each spillway weir design is based on the concept of providing an overflow weir with a depth more similar to the natural migration depth of juvenile salmonids than conventional spill bays. Little Goose Dam was the last of the four lower Snake River dams to have a spillway weir installed. This was the first year that some form of surface passage device was operating at all Snake River and Columbia River dams between Lewiston, Idaho, and the Columbia River estuary. The study design stipulated that a total of 30 percent of the river discharge would continuously be passed over the TSW and the conventional spill bays, and this percentage was achieved. The TSW also was to be operated at the 'low crest' elevation during the spring and the 'high crest' elevation during the summer, but the TSW was only operated at the low crest elevation during this study. Behavior, passage, and survival of spring and summer juvenile salmonid migrants passing through Little Goose Dam were examined using radio telemetry. Survival was estimated using the Route Specific Survival Model (RSSM) by releasing tagged fish near Central Ferry State Park 21 kilometers upstream of the dam and in the tailrace approximately 0.5 kilometer downstream of the dam. From April 18 to May 21, 2009, 1,520 yearling Chinook salmon (Oncorhynchus tshawytscha) and 1,517 juvenile steelhead (O. mykiss) were radio tagged and released. From June 6 to July 5, 2009, 4,251 subyearling Chinook salmon (O. tshawytscha) were radio tagged and released. Release dates of subyearling Chinook salmon were selected to avoid 'reservoir

Splicing of goose parvovirus pre-mRNA influences cytoplasmic translation of the processed mRNA

Translation of goose parvovirus (GPV) 72 kDa Rep 1 is initiated from unspliced P9-generated mRNAs in ORF1 from the first in-frame AUG (537 AUG); however, this AUG is bypassed in spliced P9-generated RNA: translation of the 52 kDa Rep 2 protein from spliced RNA is initiated in ORF2 at the next AUG downstream (650 AUG). Usage of the 537 AUG was restored in spliced RNA when the GPV intron was replaced with a chimeric SV40 intron, or following specific mutations of the GPV intron which did not appear in the final spliced mRNA. Additionally, 650 AUG usage was gained in unspliced RNA when the GPV intron splice sites were debilitated. Splicing-dependent regulation of translation initiation was mediated in cis by GPV RNA surrounding the target AUGs. Thus, nuclear RNA processing of GPV P9-generated pre-mRNAs has a complex, but significant, effect on alternative translation initiation of the GPV Rep proteins.

Effects of migratory geese on plant communities of an Alaskan salt marsh
Zacheis, Amy B.; Hupp, Jerry W.; Ruess, Roger W.
2001-01-01
1. We studied the effects of lesser snow geese (Anser caerulescens caerulescens) and Canada geese (Branta canadensis) on two salt marsh plant communities in Cook Inlet, Alaska, a stopover area used during spring migration. From 1995 to 1997 we compared plant species composition and biomass on plots where geese were excluded from feeding with paired plots where foraging could occur. 2. Foraging intensity was low (650-1930 goose-days km-2) compared to other goose-grazing systems. 3. Canada geese fed mainly on above-ground shoots of Triglochin maritimum, Puccinellia spp. and Carex ramenskii, whereas the majority of the snow goose diet consisted of below-ground tissues of Plantago maritima and Triglochin maritimum. 4. Plant communities responded differently to goose herbivory. In the sedge meadow community, where feeding was primarily on above-ground shoots, there was no effect of grazing on the dominant species Carex ramenskii and Triglochin maritimum. In the herb meadow community, where snow geese fed on Plantago maritima roots and other below-ground tissues, there was a difference in the relative abundance of plant species between treatments. Biomass of Plantago maritima and Potentilla egedii was lower on grazed plots compared with exclosed, whereas biomass of Carex ramenskii was greater on grazed plots. There was no effect of herbivory on total standing crop biomass in either community. The variable effect of herbivory on Carex ramenskii between communities suggests that plant neighbours and competitive interactions are important factors in a species' response to herbivory. In addition, the type of herbivory (above- or below-ground) was important in determining plant community response to herbivory. 5. Litter accumulation was reduced in grazed areas compared with exclosed in both communities. Trampling of the previous year's litter into the soil surface by geese incorporated more litter into soils in grazed areas. 6. This study illustrates that even light herbivore

The goose is an economically important poultry species and a principal natural host of avian viruses. This study aimed to determine the effects of selenium on the immune response of geese. Under selenium stimulation, gene expression profiling was investigated using transcriptome sequencing. The selenoproteins were promoted by selenium stimulation, while the heat shock proteins, interleukin and interferons were mainly down-regulated. After comparison, 2228 differentially expressed genes were primarily involved in immune and environmental response, and infectious disease and genetic information processing related pathways were identified. Specifically, the enzymes of the lysosomes which acted as a safeguard in preventing pathogens were mostly up-regulated and six randomly selected differentially expressed genes were validated by quantitative polymerase chain reaction. In addition, the most proportional increased transcription factor family basic helix-loop-helix (bHLH) located in the 5' flank of selenoprotein P-like protein for selenium metabolism was identified by response to the selenium stimulation in this study. These analyses show that selenium can promote immune function by activating selenoproteins, transcript factors and lysosome pathway related genes, while weakening cytokine content genes in geese. © 2017 Japanese Society of Animal Science.

Full Text Available Andes virus (ANDV and ANDV-like viruses are responsible for most hantavirus pulmonary syndrome (HPS cases in South America. Recent studies in Chile indicate that passive transfer of convalescent human plasma shows promise as a possible treatment for HPS. Unfortunately, availability of convalescent plasma from survivors of this lethal disease is very limited. We are interested in exploring the concept of using DNA vaccine technology to produce antiviral biologics, including polyclonal neutralizing antibodies for use in humans. Geese produce IgY and an alternatively spliced form, IgYΔFc, that can be purified at high concentrations from egg yolks. IgY lacks the properties of mammalian Fc that make antibodies produced in horses, sheep, and rabbits reactogenic in humans. Geese were vaccinated with an ANDV DNA vaccine encoding the virus envelope glycoproteins. All geese developed high-titer neutralizing antibodies after the second vaccination, and maintained high-levels of neutralizing antibodies as measured by a pseudovirion neutralization assay (PsVNA for over 1 year. A booster vaccination resulted in extraordinarily high levels of neutralizing antibodies (i.e., PsVNA80 titers >100,000. Analysis of IgY and IgYΔFc by epitope mapping show these antibodies to be highly reactive to specific amino acid sequences of ANDV envelope glycoproteins. We examined the protective efficacy of the goose-derived antibody in the hamster model of lethal HPS. α-ANDV immune sera, or IgY/IgYΔFc purified from eggs, were passively transferred to hamsters subcutaneously starting 5 days after an IM challenge with ANDV (25 LD50. Both immune sera, and egg-derived purified IgY/IgYΔFc, protected 8 of 8 and 7 of 8 hamsters, respectively. In contrast, all hamsters receiving IgY/IgYΔFc purified from normal geese (n=8, or no-treatment (n=8, developed lethal HPS. These findings demonstrate that the DNA vaccine/goose platform can be used to produce a candidate antiviral

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

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

Full Text Available Highly pathogenic avian influenza H5N1 (HPAI H5N1 viruses can infect mammals, including humans, causing severe systemic disease with the inhibition of the immune system and a high mortality rate. In conditions of lymphoid tissue depletion, the liver plays an important role in host defence against viruses. The changes in mice liver infected with HPAI H5N1 virus A/goose/Krasnoozerskoye/627/05 have been studied. It has been shown that the virus persistence in the liver leads to the expression of proinflammatory cytokines (TNF-α, IL-6 and intracellular proteases (lysozyme, cathepsin D, and myeloperoxidase by Kupffer cells. Defective antiviral response exacerbates destructive processes in the liver accelerating the development of liver failure.

A recent Canada goose (Branta canadensis) die-off at a petroleum refinery fly ash pond in Delaware was attributed to vanadium (V) toxicity. Because of the paucity of V toxicity data for wild birds, a series of studies was undertaken using the forms of V believed to have resulted in this incident. In 7-d single oral dose trials with mallard drakes (Anas platyrhynchos), the estimated median lethal dose (LD50) for vanadium pentoxide was 113 mg/kg body weight, while the LD50 for sodium metavanadate was 75.5 mg/kg. Sodium metavanadate was found to be even more potent (LD50 = 37.2 mg/kg) in male Canada geese. The most distinctive histopathological lesion of both forms of V was lympho-granulocytic enteritis with hemorrhage into the intestinal lumen. Vanadium accumulation in liver and kidney was proportional to the administered dose, and predictive analyses based on these data suggest that V concentrations of 10 μg/g dry weight (dw) in liver and 25 μg/g dw in kidney are associated with mortality (>90% confidence that exposure is >LD50) in mallards acutely exposed to sodium metavanadate. Chronic exposure to increasing dietary concentrations of sodium metavanadate (38.5 to 2651 ppm) over 67 d resulted in V accumulation in liver and kidney (25.2 and 13.6 μg/g dw, respectively), mild intestinal hemorrhage, blood chemistry changes, and evidence of hepatic oxidative stress in mallards, although some of these responses may have been confounded by food avoidance and weight loss. Dietary exposure of mallards to 250 ppm sodium metavanadate for 4 wk resulted in modest accumulation of V in liver and kidney (<5 μg/g dw) and mild intestinal hemorrhage. Based on these data and other observations, it is unlikely that chronic low-level dietary exposure to V poses a direct lethal hazard to wildlife. However, point sources, such as the V-laden fly ash pond encountered by geese at the petroleum refinery in Delaware, may pose a significant hazard to water birds.

Muscovy duck parvovirus (MDPV) and Goose parvovirus (GPV) are important etiological agents for Muscovy duck parvoviral disease and Derzsy's disease, respectively; both of which can cause substantial economic losses in waterfowl industry. In contrast to GPV, the complete genomic sequence data of MDPV isolates are still limited and their phylogenetic relationships largely remain unknown. In this study, the entire genome of a pathogenic MDPV strain ZW, which was isolated from a deceased Muscovy duckling in 2006 in China, was cloned, sequenced, and compared with that of other classical MDPV and GPV strains. The genome of strain ZW comprises of 5071 nucleotides; this genome was shorter than that of the pathogenic MDPV strain YY (5075 nt). All the four deleted nucleotides produced in strain ZW are located at the base-pairing positions in the palindromic stem of inverted terminal repeats (ITR) without influencing the formation of a hairpin structure. Recombination analysis revealed that strain ZW originated from genetic recombination between the classical MDPV and GPV strain. The YY strain of MDPV acts as the major parent, whereas the virulent strains YZ99-6 and B and the vaccine strain SYG61v of GPV act as the minor parents in varying degrees. Two recombination sites were detected in strain ZW, with the small recombination site surrounding the P9 promoter, and the large recombination site situated in the middle of the VP3 gene. The SYG61V strain is a vaccine strain used for preventing goose parvoviral disease. This strain was found to be solely involved in the recombination event detected in the P9 promoter region. Phylogenetic analyses between strain ZW and other classical strains of MDPV and GPV were performed. The results supported the in silico recombination analysis conclusion. MDPV Strain ZW is a novel recombinant parvovirus, and the bulk of its genome originates from the classical MDPV strain. Two virulent strains and a vaccine strain of GPV were involved in the

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

As a newly emerged infectious disease, duck "beak atrophy and dwarfism syndrome (BADS)" disease has caused huge economic losses to waterfowl industry in China since 2015. Novel goose parvovirus-related virus (NGPV) is believed the main pathogen of BADS disease; however, BADS is rarely reproduced by infecting ducks with NGPV alone. As avian circovirus infection causes clinical symptoms similar to BADS, duck circovirus (DuCV) is suspected the minor pathogen of BADS disease. In this study, an investigation was carried out to determine the coinfection of NGPV and DuCV in duck embryos and in ducks with BADS disease. According to our study, the coinfection of emerging NGPV and DuCV was prevalent in East China (Shandong, Jiangsu and Anhui province) and could be vertical transmitted, indicating their cooperative roles in duck BADS disease. © 2018 Blackwell Verlag GmbH.

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

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

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

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

Wild mallards have more "goose-like" bills than their ancestors: a case of anthropogenic influence?
Directory of Open Access Journals (Sweden)
Pär Söderquist
Full Text Available Wild populations of the world's most common dabbling duck, the mallard (Anas platyrhynchos, run the risk of genetic introgression by farmed conspecifics released for hunting purposes. We tested whether bill morphology of free-living birds has changed since large-scale releases of farmed mallards started. Three groups of mallards from Sweden, Norway and Finland were compared: historical wild (before large-scale releases started, present-day wild, and present-day farmed. Higher density of bill lamellae was observed in historical wild mallards (only males. Farmed mallards had wider bills than present-day and historical wild ones. Present-day wild and farmed mallards also had higher and shorter bills than historical wild mallards. Present-day mallards thus tend to have more "goose-like" bills (wider, higher, and shorter than their ancestors. Our study suggests that surviving released mallards affect morphological traits in wild population by introgression. We discuss how such anthropogenic impact may lead to a maladapted and genetically compromised wild mallard population. Our study system has bearing on other taxa where large-scale releases of conspecifics with 'alien genes' may cause a cryptic invasive process that nevertheless has fitness consequences for individual birds.

Canada's nuclear power programme
International Nuclear Information System (INIS)
Peden, W.
1976-01-01
Although Canada has developed the CANDU type reactor, and has an ambitious programme of nuclear power plant construction, there has been virtually no nuclear controversy. This progress was seen as a means to bring Canada out of the 'resource cow' era, and onto a more equal footing with technologically elite nations. However the Indian nuclear explosion test, waste storage problems, contamination problems arising from use of uranium ore processing waste as land fill and subsidised sale of nuclear power plants to Argentina and South Korea have initiated public and parliamentary interest. Some economists have also maintained that Canada is approaching over-supply of nuclear power and over-investment in plant. Canada has no official overall energy production plan and alternative sources have not been evaluated. (JIW)

TransCanada PipeLines Limited 1998 annual report : TransCanada energy solutions
International Nuclear Information System (INIS)
1999-01-01
Financial information from TransCanada PipeLines Limited and a review of the company's 1998 operations was made available for the benefit of shareholders. TransCanada's pipeline system transports natural gas and crude oil from Western Canada Sedimentary Basin to North America's major energy markets. Net earnings from continuing operations for 1998, before unusual charges, were $575 million ($ 355 million after unusual charges) compared to $522 million for 1997. Solid performances from the energy transmission and international business, when compared to 1997, were more than offset by a decreased contribution from energy processing. TransCanada recorded integration costs of $166 million, after tax, related to the merger with NOVA in 1998, which was the major operational accomplishment during the year, creating a seamless economic energy delivery, processing and marketing system from the wellhead to the market. tabs., figs

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

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

Constraints on productivity of wild Nene or Hawaiian geese Branta sandvicensis
Banko, P.C.
1992-01-01
I investigated constraints on the productivity of wild Nene on Hawaii and Maui during 1978-81. These populations were composed largely of captive-reared birds. Recruitment of young was low. Of 140 breeding attempts, 36% resulted in successful nests and 7% produced fledglings. Annual productivity was limited because: 1) relatively few available pairs attempted to breed (58% on Hawaii; 46% on Maui), 2) average rate of nest success was low (44%), and 3) gosling survival was low nesting suggests that many females could not accumulate sufficient body reserves for egg-laying and incubation due to poor foraging conditions or poorly developed foraging skills. Nest failure was high due to predation on eggs and incubating females by the introduced mongoose. Gosling mortality was high because of poor foraging conditions near many nests, forcing broods to travel over rugged, volcanic terrain to distant rearing areas. In addition, some goslings were killed by predators. Nene populations would benefit most from improved foraging opportunities for adult females and goslings and from reduced predator populations.

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

Active Canada 20/20: A physical activity plan for Canada.
Spence, John C; Faulkner, Guy; Costas Bradstreet, Christa; Duggan, Mary; Tremblay, Mark S
2016-03-16
Physical inactivity is a pressing public health concern. In this commentary we argue that Canada's approach to increasing physical activity (PA) has been fragmented and has lacked coordination, funding and a strategic approach. We then describe a potential solution in Active Canada 20/20 (AC 20/20), which provides both a national plan and a commitment to action from non-government and public sectors with a view to engaging corporate Canada and the general public. It outlines a road map for initiating, coordinating and implementing proactive initiatives to address this prominent health risk factor. The identified actions are based on the best available evidence and have been endorsed by the majority of representatives in the relevant sectors. The next crucial steps are to engage all those involved in public health promotion, service provision and advocacy at the municipal, provincial and national levels in order to incorporate AC 20/20 principles into practice and planning and thus increase the PA level of every person in Canada. Further, governments, as well as the private, not-for-profit and philanthropic sectors, should demonstrate leadership and continue their efforts toward providing the substantial and sustained resources needed to recalibrate Canadians' habitual PA patterns; this will ultimately improve the overall health of our citizens.

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

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

1978-01-01
The factors influencing the evolution of Canada's nuclear export policy are examined. Initially, nuclear technology was exported to establish an industry in Canada and to share the technology with other countries. After 1974 an increasingly broad range of political and social factors were taken into account and safeguards became the dominant factor. The indirect impacts of the new policy fall into two groups. One consists of the effects of Canada's leadership in taking a tough stand on safeguards. The second group of effects involve the concern of other countries about access to secure energy supplies and advanced technology.

The Habitat Evaluation Procedures were used to evaluate pre- and post-construction habitat conditions of the US Bureau of Reclamation's Palisades Project in eastern Idaho. Eight evaluation species were selected with losses expressed in the number of Habitat Units (HU's). One HU is equivalent to one acre of prime habitat. The evaluation estimated that a loss of 2454 HU's of mule deer habitat, 2276 HU's of mink habitat, 2622 HU's of mallard habitat, 805 HU's of Canada goose habitat, 2331 HU's of ruffed grouse habitat, 5941 and 18,565 HU's for breeding and wintering bald eagles, and 1336 and 704 HU's for forested and scrub-shrub wetland nongame species occurred as a result of the project. The study area currently has 29 active osprey nests located around the reservoir and the mudflats probably provide more feeding habitat for migratory shore birds and waterfowl than was previously available along the river. A comparison of flow conditions on the South Fork of the Snake River below the dam between pre- and post-construction periods also could not substantiate claims that water releases from the dam were causing more Canada goose nest losses than flow in the river prior to construction. 41 refs., 16 figs., 9 tabs.

Uranium in Canada: Billion-dollar industry
International Nuclear Information System (INIS)
Whillans, R.T.
1989-01-01
In 1988, Canada maintained its position as the world's leading producer and exporter of uranium; five primary uranium producers reported concentrate output containing 12,400 MT of uranium, or about one-third of Western production. Uranium shipments made by these producers in 1988 exceeded 13,200 MT, worth Canadian $1.1 billion. Because domestic requirements represent only 15% of current Canadian output, most of Canada's uranium production is available for export. Despite continued market uncertainty in 1988, Canada's uranium producers signed new sales contracts for some 14,000 MT, twice the 1987 level. About 90% of this new volume is with the US, now Canada's major uranium customer. The recent implementation of the Canada/US Free Trade agreement brings benefits to both countries; the uranium industries in each can now develop in an orderly, free market. Canada's uranium industry was restructured and consolidated in 1988 through merger and acquisition; three new uranium projects advanced significantly. Canada's new policy on nonresident ownership in the uranium mining sector, designed to encourage both Canadian and foreign investment, should greatly improve efforts to finance the development of recent Canadian uranium discoveries

Canada's nuclear non-proliferation policy
International Nuclear Information System (INIS)
1985-01-01
Canada's non-proliferation and safeguards policy has two objectives: 1) to promote the emergence of a more effective and comprehensive international non-proliferation regime; and 2) to assure the Canadian people and the international community that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the NPT, by promoting reliance upon and improvements in the IAEA safeguards system, by treating nuclear weapon and non-nuclear weapon states alike regarding Canadian nuclear exports, by working for new approaches covering the sensitive phases (e.g. reprocessing) of the nuclear fuel cycle, Canada's policy promotes attainment of the first objective. The latter objective is served through the network of bilateral nuclear agreements that Canada has put into place with its nuclear partners. Those agreements provide assurance that Canada's nuclear exports are used solely for legitimate, peaceful, nuclear energy production purposes. At the same time, Canada, having formulated its non-proliferation and safeguards policy during the period 1945 to 1980, has recognized that it has gone as far as it can on its own in this field and that from this point on any further changes should be made on the basis of international agreement. The Canadian objective in post-INFCE forums such as the Committee on Assurances of Supply is to exert Canada's best efforts to persuade the international community to devise a more effective and comprehensive international non-proliferation regime into which Canada and other suppliers might subsume their national requirements

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

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

The regional signature of anthropogenic climate change on the atmosphere and upper ocean is often difficult to discern from observational timeseries, dominated as they are by decadal climate variability. Here we argue that a long-term decline of dissolved oxygen concentrations observed in the Gulf of S. Lawrence (GoSL) is consistent with anthropogenic climate change. Oxygen concentrations in the GoSL have declined markedly since 1930 due primarily to an increase of oxygen-poor North Atlantic Central Waters relative to Labrador Current Waters (Gilbert et al. 2005). We compare these observations to a climate warming simulation using a very high-resolution global coupled ocean-atmospheric climate model. The numerical model (CM2.6), developed by the Geophysical Fluid Dynamics Laboratory, is strongly eddying and includes a biogeochemical module with dissolved oxygen. The warming scenario shows that oxygen in the GoSL decreases and it is associated to changes in western boundary currents and wind patterns in the North Atlantic. We speculate that the large-scale changes behind the simulated decrease in GoSL oxygen have also been at play in the real world over the past century, although they are difficult to resolve in noisy atmospheric data.

Canada's nuclear non-proliferation policy
International Nuclear Information System (INIS)
1982-05-01
Canada's non-proliferation safeguards policy has two objectives: 1) to promote a more effective and comprehensive international non-proliferation regime; and 2) to ensure that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the Non-Proliferation Treaty, promoting reliance upon and improvements in the IAEA safeguards system, treating nuclear weapon and non-weapon states alike, and working for new approaches covering reprocessing, Canada promotes attainment of the first objective. The second is served through the network of bilateral nuclear agreements that Canada has put into place with its partners. The Canadian objective in post-INFCE forums is to persuade the international community to devise a more effective and comprehensive non-proliferation regime into which Canada and other suppliers may subsume their national requirements

Groundwater, surface water, and soil in the Goose Lake oil field in northeastern Montana have been affected by Cl−-rich oil-field brines during long-term petroleum production. Ongoing multidisciplinary geochemical and geophysical studies have identified the degree and local extent of interaction between brine and groundwater. Fourteen samples representing groundwater, surface water, and brine were collected for Sr isotope analyses to evaluate the usefulness of 87Sr/86Sr in detecting small amounts of brine. Differences in Sr concentrations and 87Sr/86Sr are optimal at this site for the experiment. Strontium concentrations range from 0.13 to 36.9 mg/L, and corresponding 87Sr/86Sr values range from 0.71097 to 0.70828. The local brine has 168 mg/L Sr and a 87Sr/86Sr value of 0.70802. Mixing relationships are evident in the data set and illustrate the sensitivity of Sr in detecting small amounts of brine in groundwater. The location of data points on a Sr isotope-concentration plot is readily explained by an evaporation-mixing model. The model is supported by the variation in concentrations of most of the other solutes.

Taxi and limousine industry in Canada
International Nuclear Information System (INIS)
Monteiro, J.; Civettini, S.
2007-01-01
Taxi and limousine service plays an important role in the movement of people within a city. In 2004, the total revenue in this industry in Canada was $1.305 billion, and an estimated 35,339 carriers served the industry. In Canada, economic and safety regulations of taxi supply were imposed in most cities during the 1930s and 1940s and continue to this date. Although the industry is regulated, the competition law also applies. The appropriateness of these regulations continues to be challenged and regulatory reforms in the major cities in Canada have concentrated their efforts on increasing the rate of services, improving the quality of vehicles and enhancing the training of taxi drivers. Indicators for the 1999-2004 period reveal that the taxi and limousine industry in Canada did not perform very well. Revenue increased by only 1.7 per cent per year and margins deteriorated by -1.78 per cent together with the operating ratio. The purpose of this paper was to examine the taxi and limousine industry in Canada. First, the structure of the industry in Canada was examined followed by a review of the economic regulation of the industry. Recent regulatory developments in Canada and in other countries were then reviewed with arguments for or against deregulation. 28 refs., 2 tabs

Petro-Canada's 2001 report in support of Canada's climate change voluntary challenge and registry
International Nuclear Information System (INIS)
2001-01-01
One of the leading oil and gas companies in Canada, Petro-Canada is committed to the Climate Change Voluntary Challenge and Registry (VCR) Program. In this document, the major initiatives undertaken by Petro-Canada with the aim of reducing greenhouse gas emissions were highlighted. The successes in improving energy efficiency in the process of reducing greenhouse gas emissions were reviewed. A major accomplishment in 2000 was the total greenhouse gas emissions resulting from the operations of Petro-Canada that were below the level of 1990, even in the face of a one-third increase in production over the last ten years. As a result, a reduction in excess of 45,000 tonnes of ongoing annual emissions was achieved. The targets that were set are a one per cent reduction every year from 2000 to 2005 through reductions in fuel consumption. The Production Energy Intensity (PEI) of the upstream was improved in 2000 by 11 per cent when compared to 1999 value. Energy efficiency projects have been allocated a total of 4 million dollars in capital funds, and emerging technologies in alternate fuels are being monitored to enable Petro-Canada to reduce the emissions of greenhouse gases. Several education projects are being funded to enhance public awareness of climate change issues. 4 tabs., 7 figs

Canada's isotope crisis : what next?
International Nuclear Information System (INIS)
Nathwani, J.; Wallace, D.
2010-01-01
Canada urgently requires a rigorous debate on the strategic options for ensuring a robust, reliable, and affordable supply of radioactive isotopes. Should the debate be confined to how Canada can best develop the necessary technologies solely for our own use or should Canada abandon the idea of producing its own isotope supply and any future aspirations to serve the global market? Canada's Isotope Crisis focuses on the central policy question: do we dare to try to shape the future or do we retreat into silence because we are not prepared to make the necessary investments for the future well-being of Canadians? This volume showcases pointed essays and analysis from members of the academy and individuals who have made contributions to the development of medical isotopes and pioneered their use in medical practice. It also includes commentary from those involved in the production, manufacturing, processing, and distribution of isotopes. Canada's Isotope Crisis is a multi-disciplinary effort that addresses the global dimension of isotope supply and combines expert opinions on the present and past with knowledge of the relevant government agencies and the basis for their decisions at critical junctures.

Suicide policy in Canada: lessons from history.
Spiwak, Rae; Elias, Brenda; Bolton, James M; Martens, Patricia J; Sareen, Jitender
2012-07-18
In Canada, suicide has transitioned from being a criminal activity with much associated stigma, to being a public health concern that needs to be managed by governments and clinicians in a culturally sensitive manner. In Canada and worldwide, the social attitudes toward and legal interpretation of suicide have been dynamic. Much has been proposed in the development of suicide policy in Canada, however Canada is unique in that it remains one of the only industrialized countries without a national suicide prevention strategy. The current article provides a critical review of the history of suicide in Canada, as well as an appraisal of Canadian suicide prevention policies and key government and political milestones that have impacted suicide policy. Current activity regarding a national suicide prevention strategy in Canada is discussed, as well as potential options for clinician involvement.

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

Petro-Canada annual report, 1992
International Nuclear Information System (INIS)
1993-01-01
Petro-Canada was formed as Canada's national energy corporation by an act of Parliament in 1975. Operations began in January 1976, and the company was privatized in July 1991. In 1992, Petro-Canada markedly improved its operating performance by sharply cutting operating and overhead costs. Strategy in the company's resource division was refocused to concentrate future investment in western Canada light oil and natural gas and in Grand Banks light oil. Petro-Canada sold a 5% interest in the Syncrude oil sands project for $132 million as part of its plan to rebalance its portfolio. In the products division, Petro-Canada is reducing capacity and eliminating inefficient parts of its marketing network as a response to low demand. Operating earnings improved $252 million to reach $109 million, versus a $143 million loss in 1991. Net earnings were $9 million, compared to a $598 million loss in 1991. Total oil and natural gas liquids production was 80,000 bbl/d and natural gas production was 517 million ft 3 /d. Refined product sales were 43,000 m 3 /d at an average refinery utilization of 72%. Proved oil and natural gas liquids reserves were 417 million bbl and proved natural gas reserves were 2.4 trillion ft 3 . Debt was reduced by almost $700 million during 1992. The year's activities in production and sales of natural gas, synthetic and natural crude oil, gasoline, and oil sands are summarized. A 6-year operating and financial summary is included, along with a financial statement. 11 figs., 17 tabs

Natural hydrocarbon gases in Canada: the resource base
International Nuclear Information System (INIS)
Osadetz, K.G.
1997-01-01
The Geological Survey of Canada (GSC) has an ongoing national hydrocarbon resource assessment project which examines, characterizes and quantifies the hydrocarbon resource potential of Canada. In this paper the distribution, characteristics and sizes of conventional and unconventional natural gas resources in Canada are summarized. Four topics were addressed: (1) the origins of conventional and unconventional natural hydrocarbon gases in Canada, (2) the resource assessment techniques used at the GSC, with emphasis on predicting undiscovered reserves, (3) the setting, distribution and size of the conventional natural gas endowment of Canada in a geographic and geological context, and (4) the indications of unconventional natural gas resource endowment in Canada. Conventional in-place natural gas resources for Canada was estimated at 26.8 trillion cubic metres of which 54 per cent comes from the Western Canada Sedimentary Basin. The national inventory of unconventional in-place gas resource is 3,460 trillion cubic metres. At current rates of production, the expected life expectancy for the in-place conventional natural gas resource base was estimated to be about 150 years. 1 tab., 9 figs

Australia's and Canada's real wage experiences between 1870 and 1913 were distinctive. Faster productivity growth underpinned Canada's overtaking of Australia's wage levels. The globalization forces of migration and trade also shaped their comparative wages, principally by reducing wage growth...... in Canada. Immigration increased slightly Australia's real wages, but reduced wage levels in Canada, and tempered there the beneficial effects of rising productivity and improving terms of trade. In contrast, wage earners' share of national income rose after 1890 in Australia, with the productivity slowdown...... hitting chiefly rents and profits. Distributional shifts favouring wage earners in Australia, and the depressing effects of mass immigration on wages in Canada, limited Canada's wage lead before 1914, despite her faster productivity growth...

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

The nuclear industry in Canada
International Nuclear Information System (INIS)
Anderson, D.; Broughton, W.
1992-01-01
The nuclear industry in Canada comprises three identifiable groups: (1) Atomic Energy of Canada Limited (AECL), (2) electrical utilities that use nuclear power plants, (3) private engineering and manufacturing companies. At the end of World War II, AECL was charged with investigating and developing peaceful uses of atomic power. Included in the results is the Canada deuterium uranium (CANDU) reactor, a peculiarly Canadian design. The AECL maintains research capability and operates as the prime nuclear steam supply system supplier. Utilities in three Canadian provinces operate nuclear power plants, New Brunswick, Quebec, and Ontario, with the majority in Ontario. From the beginning of the nuclear program in Canada, private industry has been an important partner to AECL and the utilities, filling roles as manufacturing subcontractors and as component designers. The prime objective of this paper is to illuminate the role of private industry in developing and maintaining a competitive world-class nuclear industry

Canada's contribution to global research in cardiovascular diseases.
Nguyen, Hai V; de Oliveira, Claire; Wijeysundera, Harindra C; Wong, William W L; Woo, Gloria; Grootendorst, Paul; Liu, Peter P; Krahn, Murray D
2013-06-01
The burden of cardiovascular disease (CVD) in Canada and other developed countries is growing, in part because of the aging of the population and the alarming rise of obesity. Studying Canada's contribution to the global body of CVD research output will shed light on the effectiveness of investments in Canadian CVD research and inform if Canada has been responding to its CVD burden. Search was conducted using the Web-of-Science database for publications during 1981 through 2010 on major areas and specific interventions in CVD. Search was also conducted using Canadian and US online databases for patents issued between 1981 and 2010. Search data were used to estimate the proportions of the world's pool of research publications and of patents conducted by researchers based in Canada. The results indicate that Canada contributed 6% of global research in CVD during 1981 through 2010. Further, Canada's contribution shows a strong upward trend during the period. Based on patent data, Canada's contribution level was similar (5%-7%). Canada's contribution to the global pool of CVD research is on par with France and close to the UK, Japan, and Germany. Canada's contribution in global CVD research is higher than its average contribution in all fields of research (6% vs 3%). As the burden of chronic diseases including CVD rises with Canada's aging population, the increase in Canadian research into CVD is encouraging. Copyright © 2013 Canadian Cardiovascular Society.

Climate change and human activities cause uncertain changes to species biodiversity by altering their habitat. The uncertainty of climate change requires planners to balance the benefit and cost of making conservation plan. Here optimal protection approach for Lesser White-fronted Goose (LWfG) by coupling Modern Portfolio Theory (MPT) and Marxan selection were proposed. MPT was used to provide suggested weights of investment for protected area (PA) and reduce the influence of climatic uncertainty, while Marxan was utilized to choose a series of specific locations for PA. We argued that through combining these two commonly used techniques with the conservation plan, including assets allocation and PA chosing, the efficiency of rare bird's protection would be enhanced. In MPT analyses, the uncertainty of conservation-outcome can be reduced while conservation effort was allocated in Hunan, Jiangxi and Yangtze River delta. In Marxan model, the optimal location for habitat restorations based on existing nature reserve was identified. Clear priorities for the location and allocation of assets could be provided based on this research, and it could help decision makers to build conservation strategy for LWfG.

Habitat Evaluation Procedures (HEP) Report; Calispell Creek Project, Technical Report 2004-2005.
Energy Technology Data Exchange (ETDEWEB)
Entz, Ray
2005-02-01
On July 13, 2004, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the Calispell Creek property, an acquisition completed by the Kalispel Tribe of Indians in February 2004. Evaluation species and appropriate models include Canada goose, mallard, muskrat, yellow warbler, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The Calispell Creek Project provides a total of 138.17 Habitat Units (HUs) for the species evaluated. Emergent wetland habitat provides 5.16 HUs for mallard and muskrat. Grassland provides 132.02 HUs for mallard and Canada goose. Scrub-shrub vegetation provides 0.99 HUs for yellow warbler and white-tailed deer. The objective of using HEP at the Calispell Creek Project and other protected properties is to document the quality and quantity of available habitat for selected wildlife species. In this way, HEP provides information on the relative value of the same area at future points in time so that the effect of management activities on wildlife habitat can be quantified. When combined with other tools, the baseline HEP will be used to determine the most effective on-site management, restoration, and enhancement actions to increase habitat suitability for targeted species. The same process will be replicated every five years to quantitatively evaluate the effectiveness of management strategies in improving and maintaining habitat conditions while providing additional crediting to BPA for enhanced habitat values.

Differentiating Canada: The Future of the Canada-US Relationship
Directory of Open Access Journals (Sweden)
Wendy Dobson
2010-11-01
Full Text Available Turbulence will mark the world economy in the coming decade as Canada’s traditional trading partners in North America and Europe struggle with slow growth and rising structural unemployment and move, as they must, to restore the health of their public finances. Settling for the status quo is not a compelling option as the US border thickens and Canada stays on the sidelines in two areas vital to its long-term interest: climate change policy and trade liberalization. In this context, the Policy Brief evaluates the strategic options for Canada’s long-standing economic relationship with the United States. The authors propose a two-part proactive strategy. The first part is for Canada to differentiate its economy by building on its macroeconomic, financial and energy strengths relative to the United States and by shaping a best-practice North American climate change policy. The second part of the strategy is to deepen NAFTA by participating in the Trans-Pacific Partnership (TPP, a comprehensive, highquality FTA that has strategic attention of the US administration. Any country can join by accepting the agreement’s provisions. The TPP offers at least two strategic opportunities: a comprehensive negotiation in which Canada, the United States and Mexico could upgrade NAFTA and a way to diversify and deepen trade and investment liberalization with major economies in the Asia-Pacific region.

Pain medicine--a new credential in Canada.
Morley-Forster, Patricia; Karpinski, Jolanta
2015-06-01
In 2010, Pain Medicine was formally recognized as a subspecialty in Canada by the Royal College of Physicians and Surgeons of Canada, a national organization with oversight of the medical education of specialists in Canada. The first trainees began their training at the Western University, London, Canada in July, 2014. This article traces the process of Pain Medicine's development as a discipline in Canada and outlines its multiple entry routes, 2-year curriculum, and assessment procedures. The application for specialty status was initiated in 2007 with the understanding that while Anesthesiology would be the parent specialty, the curriculum would train clinicians in a multidisciplinary setting. To receive recognition as a Royal College subspecialty, Pain Medicine had to successfully pass through three phases, each stage requiring formal approval by the Committee on Specialties. The multiple entry routes to this 2-year subspecialty program are described in this article as are the objectives of training, the curriculum, assessment of competency and the practice-eligibility route to certification. The process of accreditation of new training programs across Canada is also discussed. The new Pain Medicine training program in Canada will train experts in the prevention, diagnosis, treatment and rehabilitation of the spectrum of acute pain, cancer pain and non-cancer pain problems. These physicians will become leaders in education, research, advocacy and administration of this emerging field. Wiley Periodicals, Inc.

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

Goose populations molting in the Teshekpuk Lake Special Area of the National Petroleum Reserve-Alaska have changed in size and distribution over the past 30 years. Black brant (Branta bernicla nigricans) are relatively stable in numbers but are shifting from large, inland lakes to salt marshes. Concurrently, populations of greater white-fronted geese (Anser albifrons frontalis) have increased seven fold. Populations of Canada geese (Branta canadensis and/or B. hutchinsii) are stable with little indication of distributional shifts. The lesser snow goose (Anser caerulescens caerulescens) population is proportionally small, but increasing rapidly. Coastline erosion of the Beaufort Sea has altered tundra habitats by allowing saltwater intrusion, which has resulted in shifts in composition of forage plant species. We propose two alternative hypotheses for the observed shift in black brant distribution. Ecological change may have altered optimal foraging habitats for molting birds, or alternatively, interspecific competition between black brant and greater white-fronted geese may be excluding black brant from preferred habitats. Regardless of the causative mechanism, the observed shifts in species distributions are an important consideration for future resource planning. ?? 2007 Springer-Verlag.

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

An International Species Management Plan for the Svalbard population of the pink-footed goose was adopted under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds in 2012, the first case of adaptive management of a migratory waterbird population in Europe. An international working group (including statutory agencies, NGO representatives and experts) agreed on objectives and actions to maintain the population in favourable conservation status, while accounting for biodiversity, economic and recreational interests. Agreements include setting a population target to reduce agricultural conflicts and avoid tundra degradation, and using hunting in some range states to maintain stable population size. As part of the adaptive management procedures, adjustment to harvest is made annually subject to population status. This has required streamlining of monitoring and assessment activities. Three years after implementation, indicators suggest the attainment of management results. Dialogue, consensus-building and engagement among stakeholders represent the major process achievements.

Cardiac Rehabilitation Series: Canada
Grace, Sherry L.; Bennett, Stephanie; Ardern, Chris I.; Clark, Alexander
2015-01-01
Cardiovascular disease is among the leading causes of mortality and morbidity in Canada. Cardiac rehabilitation (CR) has a long robust history here, and there are established clinical practice guidelines. While the effectiveness of CR in the Canadian context is clear, only 34% of eligible patients participate, and strategies to increase access for under-represented groups (e.g., women, ethnic minority groups) are not yet universally applied. Identified CR barriers include lack of referral and physician recommendation, travel and distance, and low perceived need. Indeed there is now a national policy position recommending systematic inpatient referral to CR in Canada. Recent development of 30 CR Quality Indicators and the burgeoning national CR registry will enable further measurement and improvement of the quality of CR care in Canada. Finally, the Canadian Association of CR is one of the founding members of the International Council of Cardiovascular Prevention and Rehabilitation, to promote CR globally. PMID:24607018

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.

1992-03-01
Petro-Canada is Canada's national energy corporation, formed by an Act of Parliament in 1975. Operations began in January 1976. In 1991, Petro-Canada became a public company, issuing 19.5% of its common shares for net proceeds of $523 million. Heavy losses in the first half of the year were driven by price volatility following the Persian Gulf war. Cash flow return on capital employed was 7.2%, and a net loss of $598 million was posted. The Klua gas field was brought on stream only 30 months after discovery, an important gas discovery was made in British Columbia, and production and sales of natural gas increased. This annual report presents a corporate profile, a statement of corporate responsibility, and the year's activities in production and sales of natural gas, synthetic and natural crude oil and gasoline. Details are also provided of Petro-Canada's financial and operational restructuring in view of the declining revenues being obtained. A financial review from 1986 to the present is included, along with a glossary of financial terms, a financial statement, and a 5-year summary.

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

Stewart, Murray J.
1998-01-01
This paper gives a broad update on all facets of the Canadian nuclear industry and demonstrates Canada's continuing commitment to nuclear technology. Canada has developed a global leadership position in nuclear technology for power generation, uranium production and isotope supply. This commitment is being further enhanced by successes in international markets with Candu technology, new uranium mine developments in our province of Saskatchewan, and expanding isotope capabilities including the construction of two new production reactors. Korea's economy is benefiting through collaboration with Canada's leading nuclear companies, both in Korea and Canada. These collaborations have the potential to expand considerably with the implementation of the Kyoto Framework Convention on Climate Change and the anticipated increased demand for new nuclear power generation installations in all major global markets. Much has been publicized about the situation surrounding Ontario Hydro Nuclear and its nuclear recovery program. This paper gives the background and highlights the actions within Ontario and Ontario Hydro designed to ensure the long term recovery of all twenty nuclear units in Ontario. The presentation at the conference will bring the audience completely up-to-date on recent events. (author)

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

Emerging Churches in Post-Christian Canada
Directory of Open Access Journals (Sweden)
Steven Studebaker
2012-09-01
Full Text Available The traditional mainline and evangelical churches in Canada, as in most western countries, are either in decline or static. Taken as a measure of the future, the prospects for Christianity in Canada, and more broadly the West, are bleak. Post-Christian Canada, however, contains thriving alternative and innovative forms of church, often called ‘emerging’ churches. They take many forms of expression, but share common theological convictions. Based on site research and personal interviews, this article describes the various types and contexts of these churches in Canada. It then highlights three of their central theological characteristics. First, rejecting the ‘culture wars’ social involvement of Christendom churches, they embrace practices and initiatives that transform their local communities. Second, they embrace an incarnational and contextual understanding of Christian life and ministry. Eschewing mega-church franchise models, they endeavor to shape their ministry to the their local communities. Third, they adopt a comprehensive rather than compartmental spirituality.

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

Infection of clinically susceptible ducks, including cherry valley and Muscovy ducks, with a novel goose parvovirus (GPV)-related virus (N-GPV) can result in beak atrophy and dwarfism syndrome (BADS). To obtain new insights into the host range and pathogenic potential of this novel waterfowl parvovirus, cherry valley ducklings (n=20) were experimentally infected with N-GPV strain SDLC01. An equal number of ducklings served as uninfected controls. The appearance of clinical signs, histopathological changes, viral shedding, and seroconversion was monitored for 20 days post-infection. Infection status of all ducks was monitored using indirect ELISA, virus neutralization test, nested PCR, clinical indicators, and microscopic examination. Three ducks developed the typical clinical, gross, and histological changes of BADS. By study day 6, the infected ducks had seroconverted to N-GPV. The antibodies raised were neutralizing against the SDLC01 strain in vitro. Here we successfully developed an experimental infection model for studying the pathogenicity and role of N-GPV in BADS.

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

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

Comparing pyloromyotomy outcomes across Canada.
Ednie, Alexander C; Amram, Ofer; Schuurman, Nadine; Yanchar, Natalie L
2017-05-01
Changing patterns of referral and management of hypertrophic pyloric stenosis (HPS) in North America have recently been described. Comfort with perioperative management, anesthesia, and corrective surgery have been cited as reasons for these changes. Our primary objective was to assess pyloromyotomy outcomes between different hospital types across Canada. The secondary objective was to geospatially map all pyloromyotomies to identify regions of higher HPS incidence across Canada. Data of all pyloromyotomies done between 2011 and 2013 were acquired from Canadian Institute for Health Information (CIHI). Complication rates and length of hospital stay (LOS) were analyzed. Postal codes for each patient were used to geospatially map regions of higher HPS incidence. A total of 1261 pyloromyotomies were assessed. There was no difference in LOS or complication rates between different hospital types or surgeon group. Open pyloromyotomies were done in 75% of the cases. Several regions of higher HPS incidence were identified across Canada. This study found no difference in complication rate or LOS stay between hospital type and surgeon type across Canada. This may reflect a previously identified referral trend in the United States towards pediatric centers. Several regions of higher HPS incidence were identified, and may aid in identifying genetic elements causing HPS. 2c. Crown Copyright © 2017. Published by Elsevier Inc. All rights reserved.

Leaving Sweden behind: Gains in life expectancy in Canada.
Auger, Nathalie; Le Serbon, Emilie; Rostila, Mikael
2015-06-01
Sweden and Canada are known for quality of living and exceedingly high life expectancy, but recent data on how these countries compare are lacking. We measured life expectancy in Canada and Sweden during the past decade, and identified factors responsible for changes over time. We calculated life expectancy at birth for Canada and Sweden annually from 2000 to 2010, and determined the ages and causes of death responsible for the gap between the two countries using Arriaga's method. We determined how population growth, ageing, and mortality influenced the number of deaths over time. During 2000-2010, life expectancy in Canada caught up with Sweden for men, and surpassed Sweden by 0.4 years for women. Sweden lost ground owing to a slower reduction in circulatory and tumour mortality after age 65 years compared with Canada. Nonetheless, population ageing increased the number of deaths in Canada, especially for mental and nervous system disorders. In Sweden, the number of deaths decreased. In only one decade, life expectancy in Canada caught up and surpassed Sweden due to rapid improvements in circulatory and tumour mortality. Population ageing increased the number of deaths in Canada, potentially stressing the health care system more than in Sweden. © 2015 the Nordic Societies of Public Health.

Climate Change and Malaria in Canada: A Systems Approach
Directory of Open Access Journals (Sweden)
L. Berrang-Ford
2009-01-01
Full Text Available This article examines the potential for changes in imported and autochthonous malaria incidence in Canada as a consequence of climate change. Drawing on a systems framework, we qualitatively characterize and assess the potential direct and indirect impact of climate change on malaria in Canada within the context of other concurrent ecological and social trends. Competent malaria vectors currently exist in southern Canada, including within this range several major urban centres, and conditions here have historically supported endemic malaria transmission. Climate change will increase the occurrence of temperature conditions suitable for malaria transmission in Canada, which, combined with trends in international travel, immigration, drug resistance, and inexperience in both clinical and laboratory diagnosis, may increase malaria incidence in Canada and permit sporadic autochthonous cases. This conclusion challenges the general assumption of negligible malaria risk in Canada with climate change.

The juvenile fish facility at Little Goose Dam is operated seasonally to collect and bypass downstream migrating smolts and keep them from passing through the turbine blades. Fish are diverted from turbines by traveling screens as they sound in the forebay to pass the dam. A small percentage of the passing fish are sampled on a daily basis to provide information on fish condition, species composition, migration timing, and size distribution. Oregon Department of Fish and Wildlife personnel perform daily fish sampling and data collection. Physical operation of the facility is the responsibility of the US Army Corps of Engineers. Data is reported to the Fish Passage Center daily by means of electronic data transfer. Funding for this project was provided through the Smolt Monitoring Program administered by the Fish Passage Center. Overall, the number of fish collected and sampled in 1996 was a reduction from the previous years of operation. The 1996 migration season was characterized by higher than average flows and greater spill frequency at the dam. It was the first year that coho salmon were obtained in the sample. The predominant species collected was steelhead with hatchery fish outnumbering wild fish by a ratio of 8:1. An increased emphasis was placed on gas bubble trauma examination and a routine, consistent effort was implemented using a protocol established by the Fish Passage Center. The objective of the gas bubble trauma (GBT) examinations was to document the relative incidence of symptoms throughout the migration season

Natural gas resources in Canada
International Nuclear Information System (INIS)
Meneley, R.A.
2001-01-01
Natural gas is an important component in many of the technologies aimed at reducing greenhouse gas emissions. In order to understand the role that natural gas can play, it is important to know how much may be present, where it is, when can it be accessed and at what cost. The Canadian Gas Potential Committee has completed its second report 'Natural Gas Potential in Canada - 2001' (CGPC, 2001). This comprehensive study of exploration plays in Canada addresses the two issues of 'how much may be present' and 'where is it'. The Report deals with both conventional gas and non-conventional gas. One hundred and seven Established Conventional Exploration Plays, where discoveries of gas exist, have been assessed in all of the sedimentary basins in Canada. In addition, where sufficient information was available, twelve Conceptual Exploration Plays, where no discoveries have been made, were assessed. Sixty-five other Conceptual Plays were described and qualitatively ranked. An experienced volunteer team of exploration professionals conducted assessments of undiscovered gas potential over a four-year period. The team used technical judgment, statistical techniques and a unique peer review process to make a comprehensive assessment of undiscovered gas potential and estimates of the size of individual undiscovered gas accumulations. The Committee assessed all gas in place in individual exploration plays. For Established Plays, estimates of Undiscovered Nominal Marketable Gas are based on the percentage of the gas in place that is marketable gas in the discovered pools in a play. Not all of the Nominal Marketable Gas will be available. Some underlies areas where exploration is not possible, such as parks, cities and other closed areas. Some will be held in gas pools that are too small to be economic and some of the pools will never be found. In some areas no production infrastructure will be available. Detailed studies of individual exploration plays and basins will be required

Habitat Evaluation Procedures (HEP) Report; West Beaver Lake Project, Technical Report 2005
Energy Technology Data Exchange (ETDEWEB)
Entz, Ray
2005-05-01
On September 7, 2004, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the West Beaver Lake property, an acquisition completed by the Kalispel Tribe of Indians in September 2004. Evaluation species and appropriate models include bald eagle, black-capped chickadee, mallard, muskrat, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The West Beaver Lake Project provides a total of 82.69 Habitat Units (HUs) for the species evaluated. Emergent wetland habitat provides 8.80 HUs for mallard, muskrat, and Canada goose. Conifer forest habitat provides 70.33 HUs for bald eagle, black-capped chickadee, mallard, and white-tailed deer. Open water provides 3.30 HUs for mallard, muskrat, and Canada goose. The objective of using HEP at the West Beaver Lake Project and other protected properties is to document the quality and quantity of available habitat for selected wildlife species. In this way, HEP provides information on the relative value of the same area at future points in time so that the effect of management activities on wildlife habitat can be quantified. When combined with other tools, the baseline HEP will be used to determine the most effective on-site management, restoration, and enhancement actions to increase habitat suitability for targeted species. The same process will be replicated every five years to quantitatively evaluate the effectiveness of management strategies in improving and maintaining habitat conditions while providing additional crediting to BPA for enhanced habitat values.

2005-02-01
On July 13, 2004, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the Upper Trimble property, an acquisition completed by the Kalispel Tribe of Indians in March 2004. Evaluation species and appropriate models include bald eagle, black-capped chickadee, Canada goose, mallard, muskrat, yellow warbler, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The Upper Trimble Project provides a total of 250.67 Habitat Units (HUs) for the species evaluated. Wet meadow provides 136.92 HUs for mallard, muskrat, and Canada goose. Mixed forest habitat provides 111.88 HUs for bald eagle, black-capped chickadee, mallard, and white-tailed deer. Scrub-shrub vegetation provides 1.87 HUs for yellow warbler, and white-tailed deer. The objective of using HEP at the Upper Trimble Project and other protected properties is to document the quality and quantity of available habitat for selected wildlife species. In this way, HEP provides information on the relative value of the same area at future points in time so that the effect of management activities on wildlife habitat can be quantified.

Energy Policies of IEA Countries - Canada -- 2009 Review
Energy Technology Data Exchange (ETDEWEB)
NONE
2010-04-12
Canada, with its diverse and balanced portfolio of energy resources, is one of the largest producers and exporters of energy among IEA member countries. The energy sector plays an increasingly important role for the Canadian economy and for global energy security, as its abundant resource base has the potential to deliver even greater volumes of energy. The federal, provincial and territorial governments of Canada are all strongly committed to the sustainable development of the country's natural resources and have a long-standing and informed awareness of the need for each to contribute to the development of the energy sector. Furthermore, the government of Canada seeks to achieve a balance between the environmentally responsible production and use of energy, the growth and competitiveness of the economy, and secure and competitively priced energy and infrastructure. Nonetheless, the long-term sustainability of the sector remains a challenge. Due to climatic, geographic and other factors, Canada is one of the highest per-capita CO2 emitters in the OECD and has higher energy intensity than any IEA member country. A comprehensive national energy efficiency strategy, coupled with a coordinated climate change policy targeted at the key emitting sectors, is needed. Carbon capture and storage (CCS) is a priority for the federal government and presents Canada with an opportunity to develop a new technology that can reduce greenhouse gas emissions on a large scale. The IEA recommends that Canada provide international leadership in the development of CCS technology. This review analyses the energy challenges facing Canada and provides sectoral critiques and recommendations for further policy improvements. It is intended to help guide Canada towards a more sustainable energy future.

Petroleum prospectivity of the Canada Basin, Arctic Ocean
Grantz, Arthur; Hart, Patrick E.
2012-01-01
Reconnaissance seismic reflection data indicate that Canada Basin is a >700,000 sq. km. remnant of the Amerasia Basin of the Arctic Ocean that lies south of the Alpha-Mendeleev Large Igneous Province, which was constructed across the northern part of the Amerasia Basin between about 127 and 89-83.5 Ma. Canada Basin was filled by Early Jurassic to Holocene detritus from the Beaufort-Mackenzie Deltaic System, which drains the northern third of interior North America, with sizable contributions from Alaska and Northwest Canada. The basin contains roughly 5 or 6 million cubic km of sediment. Three fourths or more of this volume generates low amplitude seismic reflections, interpreted to represent hemipelagic deposits, which contain lenses to extensive interbeds of moderate amplitude reflections interpreted to represent unconfined turbidite and amalgamated channel deposits.Extrapolation from Arctic Alaska and Northwest Canada suggests that three fourths of the section in Canada Basin is correlative with stratigraphic sequences in these areas that contain intervals of hydrocarbon source rocks. In addition, worldwide heat flow averages suggest that about two thirds of Canada Basin lies in the oil or gas windows. Structural, stratigraphic and combined structural and stratigraphic features of local to regional occurrence offer exploration targets in Canada Basin, and at least one of these contains bright spots. However, deep water (to almost 4000 m), remoteness from harbors and markets, and thick accumulations of seasonal to permanent sea ice (until its possible removal by global warming later this century) will require the discovery of very large deposits for commercial success in most parts of Canada Basin. ?? 2011 Elsevier Ltd.

Opportunities in Canada's growing wind energy industry
International Nuclear Information System (INIS)
Lovshin Moss, S.; Bailey, M.
2006-01-01
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

Canada's isotope crisis : what next?
Energy Technology Data Exchange (ETDEWEB)
Nathwani, J.; Wallace, D. (eds.)
2010-07-01
Canada urgently requires a rigorous debate on the strategic options for ensuring a robust, reliable, and affordable supply of radioactive isotopes. Should the debate be confined to how Canada can best develop the necessary technologies solely for our own use or should Canada abandon the idea of producing its own isotope supply and any future aspirations to serve the global market? Canada's Isotope Crisis focuses on the central policy question: do we dare to try to shape the future or do we retreat into silence because we are not prepared to make the necessary investments for the future well-being of Canadians? This volume showcases pointed essays and analysis from members of the academy and individuals who have made contributions to the development of medical isotopes and pioneered their use in medical practice. It also includes commentary from those involved in the production, manufacturing, processing, and distribution of isotopes. Canada's Isotope Crisis is a multi-disciplinary effort that addresses the global dimension of isotope supply and combines expert opinions on the present and past with knowledge of the relevant government agencies and the basis for their decisions at critical junctures.

Raw materials for energy generation in Canada
Energy Technology Data Exchange (ETDEWEB)
Robertson, D S
1976-03-01
Canada is self-sufficient in energy. The energy demand in Canada up to the end of the century is predicted, and the present and future of the oil, gas, coal and uranium industries are considered. Since it is now Canadian policy to restrict export of energy sources, in the future Canada will probably make more domestic use of its coal reserves. An increase is forecast in the use of coal for electricity generation and as a feedstock for synthetic gas. A long lead time and large capital expenditure will be needed before coal can be transported from western Canada to markets in the east of the country. A relatively small amount of the coal reserves are extractable by surface mining, and new underground mining techniques will be needed to extract the extremely friable coal from the deformed seams in the mountains.

Petroleum prospectivity of the Canada Basin, Arctic Ocean
Grantz, A.; Hart, P.E.
2011-01-01
Reconnaissance seismic reflection data indicate that Canada Basin is a remnant of the Amerasia Basin of the Arctic Ocean that lies south of the Alpha-Mendeleev Large Igneous Province, which was constructed on the northern part of the Amerasia Basin between about 127 and 89-75 Ma. Canada Basin is filled with Early Jurassic to Holocene detritus from the Mackenzie River system, which drains the northern third of interior North America, with sizable contributions from Alaska and Northwest Canada. Except for the absence of a salt- and shale-bearing mobile substrate Canada Basin is analogous to the Mississippi Delta and the western Gulf of Mexico. Canada Basin contains about 7 to >14 km of sediment beneath the Mackenzie Prodelta on the southeast, 6 to 7 km of sediment beneath the abyssal plain on the west, and roughly 5 or 6 million cubic km of sediment. About three fourths of the basin fill generates low amplitude seismic reflections, interpreted to represent hemiplegic deposits, and a fourth of the fill generates interbedded lenses to extensive layers of moderate to high amplitude reflections interpreted to represent unconfined turbidite and amalgamated channel deposits. Extrapolation from Arctic Alaska and Northwest Canada suggests that three fourths of the section in Canada Basin may contain intervals of hydrocarbon source rocks and the apparent age of the basin suggests that it contains three of the six stratigraphic intervals that together provided >90?? of the World's discovered reserves of oil and gas.. Worldwide heat flow averages suggest that about two thirds of Canada Basin lies in the oil or gas window. At least five types of structural or stratigraphic features of local to regional occurrence offer exploration targets in Canada Basin. These consist of 1) a belt of late Eocene to Miocene shale-cored detachment folds containing with at least two anticlines that are capped by beds with bright spots, 2) numerous moderate to high amplitude reflection packets

Canada as the emerging energy superpower : testing the case
International Nuclear Information System (INIS)
Hester, A.
2007-10-01
The need for forward-thinking energy sector policies that promote Canada as a leader in the responsible and effective management of energy resources was discussed. This paper proposed a set of strategies and policy options designed to ensure that Canada becomes an energy superpower with the ability to control access to supplies and leverage energy resources in order to extend its sphere of political influence. The historical evolution of energy provision was examined in order to better define the criteria needed to attain energy superpower status. The paper also examined current global energy markets and provided a summary of Canada's current energy industry. The impact of the oil sands industry on the Canadian economy was also discussed. It was concluded that although Canada does not qualify as an energy super-power, the energy sector will play an important role in Canada's future. The implementation of forward-thinking policies may mean that Canada will emerge as a superpower in the future. 42 refs

Introducing small modular reactors into Canada
International Nuclear Information System (INIS)
Humphries, J.R.
2012-01-01
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

In 1998, we collected blood samples from 63 emperor geese (Chen canagica) on their breeding grounds on the Yukon-Kuskokwim Delta (YKD) in western Alaska, USA. We studied the relationship between selenium concentrations in whole blood and the activities of glutathione peroxidase and glutathione reductase in plasma. Experimental studies have shown that plasma activities of these enzymes are useful biomarkers of selenium-induced oxidative stress, but little information is available on their relationship to selenium in the blood of wild birds. Adult female emperor geese incubating their eggs in mid-June had a higher mean concentration of selenium in their blood and a greater activity of glutathione peroxidase in their plasma than adult geese or goslings that were sampled during the adult flight feathermolting period in late July and early August. Glutathione peroxidase activity was positively correlated with the concentration of selenium in the blood of emperor geese, and the rate of increase relative to selenium was greater in goslings than in adults. The activity of glutathione reductase was greatest in the plasma of goslings and was greater in molting adults than incubating females but was not significantly correlated with selenium in the blood of adults or goslings. Incubating female emperor geese had high selenium concentrations in their blood, accompanied by increased glutathione peroxidase activity consistent with early oxidative stress. These findings indicate that further study of the effects of selenium exposure, particularly on reproductive success, is warranted in this species.

Canada-United States oil and gas relations, 1958 to 1974
Energy Technology Data Exchange (ETDEWEB)
Nemeth, T.L.
2008-07-01
This study examined and compared the changing influence of interest groups, international forces, national security, changing economics and ideology on the energy decision- and policy-making processes of Canada and the US between 1958 and 1974. The 4 key events that marked the turning points in the Canada-US oil and gas relationship were Canada's exemption to the American Mandatory Oil Import Program (MOIP); Canada's National Oil Policy (NOP); the near revocation of Canada's MOIP exemption; and Canada's decision to phase out oil exports. In the larger context, these events signaled interdependence, intergovernmental and transgovernmental relations, and the altered bureaucratic structures of governments in both countries over this period of time. The study showed that the policy decisions concerning Canada-US oil and gas relations often depended on the personalities of, and personal relationships between Presidents and Prime Ministers, as well as the actions of key officials and their transgovernmental networks across the border.

Inventory of pediatric neurology "manpower" in Canada.
Keene, Daniel L; Humphreys, Peter
2005-08-01
To review the demographics and workload characteristics of pediatric neurology in Canada. A standardized survey questionnaire was mailed out to practicing pediatric neurologists in Canada in 2001. Variables examined were age, gender, hours on call, regular hours worked per week, type of practice and projected changes in practice over next five to ten years. Results were compared to the 1994 Pediatric Neurology Manpower Survey which had used the same survey instrument. Fifty-six (70%) pediatric neurologists practicing in Canada returned the survey. As was the case in 1994, no significant differences in workload were found based on age or gender. The average age of the practicing pediatric neurologist in 2001 was 51 years compared to 45 years in 1994. The proportion of physicians over 55 years in 2001 was 35% compared to 25% in 1994. Pediatric neurology in Canada is an aging specialty needing a significant recruitment of new members

Canada's helium output rising fast
Energy Technology Data Exchange (ETDEWEB)
1966-12-01
About 12 months from now, International Helium Limited will be almost ready to start up Canada's second helium extraction plant at Mankota, in Saskatchewan's Wood Mountain area about 100 miles southwest of Moose Jaw. Another 80 miles north is Saskatchewan's (and Canada's) first helium plant, operated by Canadian Helium and sitting on a gas deposit at Wilhelm, 9 miles north of Swift Current. It contains almost 2% helium, some COD2U, and the rest nitrogen. One year in production was apparently enough to convince Canadian Helium that the export market (it sells most of its helium in W. Europe) can take a lot more than it's getting. Construction began this summer on an addition to the Swift Current plant that will raise its capacity from 12 to 36MMcf per yr when it goes on stream next spring. Six months later, International Helium's 40 MMcf per yr plant to be located about 4 miles from its 2 Wood Mountain wells will double Canada's helium output again.

Action plan for electric mobility in Canada
International Nuclear Information System (INIS)
Gilbert, R.; Cormier, A.; Lavallee, P.
2005-01-01
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

Canada and global warming: Meeting the challenge
International Nuclear Information System (INIS)
1991-01-01
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

Canada in the changing world economy
Energy Technology Data Exchange (ETDEWEB)
Wilkinson, B.W.
1980-01-01
A broad overview and a sectoral view of Canada's economic development concudes that expansion will slow down to two percent annually during the 1980s because of the decline in young people, immigrants, and women entering the labor force. Labor productivity will have to provide any growth in per capita incomes. Market expansion into developed countries has been difficult for Canada, although depreciation of the Canadian dollar was helpful. A general picture is drawn of Canada's present situation and the key issues the country faces as a part of the international community. Three strategies are suggested to strengthen the economic performance: restructure Canadian industry, increase aid to developing countries, and continue a devalued dollar while gradually easing the balance of payments deficit. 229 references, 21 tables.

Natural disturbance impacts on Canada's forest carbon budget
International Nuclear Information System (INIS)
Kurz, W.
2004-01-01
Wildfire and insect outbreaks are major determinants of forest dynamics in Canada, transferring carbon within the ecosystem, releasing carbon into the atmosphere and influencing post-disturbance carbon dynamics. This paper discusses the impacts of global climate change on natural disturbances. Higher temperatures and drier conditions are likely to increase burned areas in Canada and will also increase the impacts of insects, allowing for an expanded range and stressing their host species. Long-term changes in disturbance regimes have already affected Canada's forest age-class structure. Statistics of lower disturbance periods and carbon production were compared with periods of higher disturbance. Scenario analyses were conducted for the period of 1996 to 2032, assuming that annual insect and fire disturbance rates in timber-productive forests were 20 per cent higher and carbon production 20 per cent lower than base scenarios using average disturbance rates. It was concluded that these conditions could cause carbon stocks in Canada's forests to decline. The future carbon balance of Canada's forests will be affected by the rate of natural and human-induced disturbances. 4 refs

Environment Canada's Children's UV Index Sun Awareness Programme
International Nuclear Information System (INIS)
Fergusson, A.
2000-01-01
In 1992, Canada introduced the UV Index forecast programme to increase public awareness of UV radiation, to support health agencies in educating the public about UV risks, and to assist individuals in making healthy lifestyle decisions. A national sun health survey in 1997 indicated that about half of adults reported taking extra precautions to protect themselves from the sun on days when the UV Index was rated 'high'. In response to this concern in 1998, Environment Canada produced an UN Index poster that was sent to 3000 elementary schools across Canada. The poster targeted children between the ages of 8 and 15 and provided information to minimise the risk to their health from solar UV radiation without spoiling their outdoor fun. Based on this experience Environment Canada produced in 1999, the Daily UV Index and Calendar Poster that was sent to 14,000 elementary schools across Canada. An UV Index website has been created to provide information to students and teachers on the science of UV radiation and the UV Index. (author)

Live attenuated vaccines have been used for control of the disease caused by goose parvovirus (GPV), but the mechanism involved in attenuation of GPV remains elusive. This report presents the complete nucleotide sequences of two live attenuated strains of GPV (82-0321V and VG32/1) that were independently developed in Taiwan and Europe, together with the parental strain of 82-0321V and a field strain isolated in Taiwan in 2006. Sequence comparisons showed that 82-0321V and VG32/1 had multiple deletions and substitutions in the inverted terminal repeats region when compared with their parental strain or the field virus, but these changes did not affect the formation of the hairpin structure essential for viral replication. Moreover, 82-0321V and VG32/1 had five amino acid changes in the non-structural protein, but these changes were located at positions distant from known functional motifs in the non-structural protein. In contrast, 82-0321V had nine changes and VG32/1 had 11 changes in their capsid proteins (VP1), and the majority of these changes occurred at positions close to the putative receptor binding sites of VP1, as predicted using the structure of adeno-associated virus 2 as the model system. Taken together, the results suggest that changes in sequence near the receptor binding sites of VP1 might be responsible for attenuation of GPV. This is the first report of complete nucleotide sequences of GPV other than the virulent B strain, and suggests a possible mechanism for attenuation of GPV.

The oil sands: A new energy vision for Canada
Energy Technology Data Exchange (ETDEWEB)
NONE
1995-12-01
Canada`s oil sands deposits were considered to offer huge potential for wealth generation and enduring social benefits. This report showed that putting in action the plan developed by the National Task Force on Oil Sands Strategies would help unlock this potential and realize the benefits; the forecast called for a doubling or tripling of oil sands production over the next 25 years. The plan should also predicted an increase in investments in oil sands since the fiscal regime would be stable and the product would be in increasing demand. New capital investment should generate significant environmental, social and economic benefits. The real outcome would be increased national prosperity, since further growth in investment would translate into thousands of skilled jobs across Canada, expansion of government revenues, and improvements to Canada`s trade balance. 1 ill.

The Canada-U.S. trade, energy, and emissions relationship
International Nuclear Information System (INIS)
McLaughlin, David
2010-01-01
A significant level of trade integration exists between Canada and the United States. For this reason, climate and energy policies in one country have economic and environmental impacts in the other. The two nations have embarked on a clean energy dialogue for the development of a clean energy strategy for Canada and this document aims at providing information and context. This paper showed that the trade relationship with the United States is important to maintaining Canada's level of prosperity. Although climate and energy policies in one country have impacts on the other, significant differences exist between their respective energy sources and emissions and a common policy would affect Canada's competitiveness. This paper showed that Canada and the United States need to discuss their clean energy and climate policies with each other but that it is not possible to implement a common policy.

Progress in electronic medical record adoption in Canada.
2015-12-01
To determine the rate of adoption of electronic medical records (EMRs) by physicians across Canada, provincial incentives, and perceived benefits of and barriers to EMR adoption. Data on EMR adoption in Canada were collected from CINAHL, MEDLINE, PubMed, EMBASE, the Cochrane Library, the Health Council of Canada, Canada Health Infoway, government websites, regional EMR associations, and health professional association websites. After removal of duplicate articles, 236 documents were found matching the original search. After using the filter Canada, 12 documents remained. Additional documents were obtained from each province's EMR website and from the Canada Health Infoway website. Since 2006, Canadian EMR adoption rates have increased from about 20% of practitioners to an estimated 62% of practitioners in 2013, with substantial regional disparities ranging from roughly 40% of physicians in New Brunswick and Quebec to more than 75% of physicians in Alberta. Provincial incentives vary widely but appear to have only a weak relationship with the rate of adoption. Many adopters use only a fraction of their software's available functions. User-cited benefits to adoption include time savings, improved record keeping, heightened patient safety, and confidence in retrieved data when EMRs are used efficiently. Barriers to adoption include financial and time constraints, lack of knowledgeable support personnel, and lack of interoperability with hospital and pharmacy systems. Canadian physicians remain at the stage of EMR adoption. Progression in EMR use requires experienced, knowledgeable technical support during implementation, and financial support for the transcription of patient data from paper to electronic media. The interoperability of EMR offerings for hospitals, pharmacies, and clinics is the rate-limiting factor in achieving a unified EMR solution for Canada.

McCauley, D.; Henault, J.
2014-01-01
On January 30, 2014, a Bill entitled the Energy Safety and Security Act, was introduced in Parliament that, among other things, would strengthen Canada's nuclear civil liability legislation by replacing the current Nuclear Liability Act. The proposed legislation also includes implementing provisions that would permit Canada to join the International Atomic Energy Agency's Convention on Supplementary Compensation for Nuclear Damage. This paper will discuss the importance of a comprehensive civil liability regime for nuclear damage to a country's legislative framework for nuclear development and will present the key elements of Canada's new legislation and the policy considerations behind them.

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

Canada is a major producer and shipper of radioactive material. Each year more than a million packages are transported in Canada. The safety record with the transport of RAM in Canada has historically been excellent. There have never been any serious injuries, overexposure or fatality or environmental consequences attributable to the radioactive nature of such material being transported or being involved in a transport accident. In Canada, the Canadian Nuclear Safety Commission (CNSC) is the prime agency of the federal government entrusted with regulating all activities related to the use of nuclear energy and nuclear substances including the packaging and transport of nuclear substances. The mission of the CNSC is to regulate the use of nuclear energy and materials to protect health, safety, security of the person and the environment and to respect Canada's international commitments on the peaceful use of nuclear energy. The division of responsibility for the regulation of transport of radioactive material has been split between Transport Canada and the CNSC. The governing Transport Canada's regulations are Transport of Dangerous Goods (TDG) Regulations and the CNSC regulations are Packaging and Transport of Nuclear Substances Regulations (PTNSR). Canada has actively participated in the development of the IAEA regulations for the safe transport of radioactive material since 1960. As an IAEA member state, Canada generally follows the requirements of IAEA regulations with few deviations. The Nuclear Safety and Control Act (NSCA) strongly supports Canada's international obligations to ensure safe packaging, transport, storage and disposal of nuclear substances, prescribed equipment and prescribed information. Prescribed equipment and prescribed information are defined in the CNSC General Nuclear Safety and Control Regulations.

Progress Towards IYA2009 in Canada
Hesser, James E.; Canada Committee, IYA
2007-12-01
We want Canadians to reconnect with the night sky through seven themes identified for national focus during IYA. Our overarching goal is to offer an engaging astronomy experience to every Canadian, with special efforts towards young people. Our partnership between the Canadian Astronomical Society, the Fédération des Astronomes Amateurs du Québec and the Royal Astronomical Society of Canada is bolstered by diverse national collaborators, e.g., planetarium and science centre communities, a national broadcaster, Canada's Aboriginal communities, the National Research Council and the Canadian Space Agency. Canada's amateur astronomers are committing magnificently to IYA and will be key to meeting our ambitious vision. We describe our themes, as well as progress towards their realization. Our vision involves many elements in common with U.S. plans, with mutual benefits arising from good liaison between the AAS and Canadian Committees. Naturally, our team is addressing responsibilities and opportunities unique to Canada. Our efforts are led by volunteers. Through programmes that create a legacy, we seek strong impact beyond 2009. We are providing activities accessible in both French and English, and are striving to leverage and strengthen existing outreach efforts wherever possible (thus avoiding reinventing the wheel and maximizing the impact of our limited resources). We are encouraging individuals to take local initiative, and are offering them moral support within the national context provided by our steering committee, as well as within the context provided by the IAU. Among examples that are described are strong efforts to involve Canada's Aboriginals, musical and arts organizations, etc., as well as our efforts to secure national exposure through, e.g., a series of postal stamps.

Reduced populations of emperor geese (Chen canagica), a Bering Sea endemic, provided the need to assess plasma biochemistry values as indicators of population health. A precursory step to such an investigation was to evaluate patterns of variability in plasma biochemistry values among age, sex, and reproductive period. Plasma from 63 emperor geese was collected on their breeding grounds on the Yukon-Kuskokwim Delta in western Alaska, USA. The geese sampled included 18 incubating adult females captured, in mid June, on their nests by using bow nets, and 30 adults and 15 goslings captured in corral traps in late July and early August, when the adults were molting their wing feathers and the goslings were 5-6 weeks old. Plasma was evaluated for 15 biochemical parameters, by comparing results among age, sex, and sampling period (incubation versus wing-feather molt). Ten of the 15 biochemical parameters assayed differed among adults during incubation, the adults during molt, and the goslings at molt, whereas sex differences were noted in few parameters.

Canada and the U.S. : a seamless border ?
International Nuclear Information System (INIS)
Bradley, P.G.; Watkins, G.C.; Doyle, K.
2003-01-01
Energy trade between Canada and the United States has increased significantly. Deregulation and the North American Free Trade Agreement (NAFTA) have rendered energy trade more market based, generating many benefits for Canada, but the distribution of gains has created conflict. There is expected to be more government control within the policy agenda between Canada and the United States as markets tighten and as natural gas and electricity prices increase. Oil and gas exports from Canada have likely stabilized to a point where they will only sustain current levels. Long term oil output lies with Alberta's oil sands, but the author noted that the ratification of the Kyoto Protocol may jeopardize access to this resource. It was also noted that integration of electricity markets is the key to prosperity for the electric power industry because its' network is in need of investment and further development. The paper discussed the challenges facing Canadian governments and regulatory agencies as the energy profile gains attention and as conflicts arise regarding deregulation and trade policy. The question remains whether NAFTA is robust enough to protect Canadian interests. As the United States government places more emphasis on energy security, Canada could take the opportunity to secure favourable access to the U.S. market and share both the costs and benefits of market integration. Canada is in a strategic position of strength when it comes to energy sector negotiations. refs., tabs

Traditional Chinese medicine research and education in Canada.
Ghayur, Muhammad Nabeel
2009-06-01
Abstract Traditional Chinese Medicine (TCM) is one of the oldest forms of medicine in the world. There has been a growing interest in TCM in Canada in terms of consumers and also among the research community. To cater for this interest, the Canadian Institute of Chinese Medicinal Research (CICMR) was established in 2004. Since its formation, CICMR has been organizing annual meetings. In 2008, the CICMR meeting, jointly organized with the Ontario Ginseng Innovation Research Centre, was held from October 16th to 19th, in London, Ontario, Canada. The meeting saw a number of participants and speakers from many countries who discussed TCM in a Canadian perspective. The talks and presentations focused on TCM practices in Asia and Canada; analytical techniques for unravelling the science behind TCM; basic and clinical research findings in the areas of cancer and cardiovascular diseases; safety and quality control issues; the regulatory and educational framework of TCM in Canada; and the latest findings in agricultural, chemical, and pharmacological research on ginseng from all over the world. The meeting successfully provided a platform for constructive discussions on TCM practices and research and education in Canada and the world.

Primary health care in Canada: systems in motion.
Hutchison, Brian; Levesque, Jean-Frederic; Strumpf, Erin; Coyle, Natalie
2011-06-01
During the 1980s and 1990s, innovations in the organization, funding, and delivery of primary health care in Canada were at the periphery of the system rather than at its core. In the early 2000s, a new policy environment emerged. This policy analysis examines primary health care reform efforts in Canada during the last decade, drawing on descriptive information from published and gray literature and from a series of semistructured interviews with informed observers of primary health care in Canada. Primary health care in Canada has entered a period of potentially transformative change. Key initiatives include support for interprofessional primary health care teams, group practices and networks, patient enrollment with a primary care provider, financial incentives and blended-payment schemes, development of primary health care governance mechanisms, expansion of the primary health care provider pool, implementation of electronic medical records, and quality improvement training and support. Canada's experience suggests that primary health care transformation can be achieved voluntarily in a pluralistic system of private health care delivery, given strong government and professional leadership working in concert. © 2011 Milbank Memorial Fund.

Taxation and our future mineral resources. [Canada
Energy Technology Data Exchange (ETDEWEB)
Brown, R D
1976-05-01
Canada's known reserves of minerals are estimated in general to be adequate to meet domestic requirements and current export demands until the mid-1980's. Beyond that time, an increasing proportion of reserves needed to maintain, let alone increase, present mineral production must come from mineral deposits not yet discovered, delineated or developed. The major question for Canada is whether present tax and regulatory programs will provide sufficient incentives for the industry to spend the large amounts required--perhaps $1.2 billion annually--in the exploration and development of mineral resources. Without such a major capital commitment to the development of new mineral resources, Canada will not be able to maintain the relative importance of its mining sector, or the contribution that the sector has made to our balance of payments, employment, and the opening of new frontiers. However, present levels of exploration and development expenditures are likely to be totally inadequate in maintaining, let alone increasing present production. The article refers to two major new reports that provide new information on Canada's resource industries and their future.

Recent developments in Canada's climate change program
International Nuclear Information System (INIS)
Sage, R.
2004-01-01
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. These materials have partially replaced cement in concrete. Canada expects to reduce carbon dioxide emissions this way by about 1.5 million tonnes per year. EcoSmart, a non-profit organization, is the main vehicle for this effort. 8 refs., 7 figs

Canada's climate change policy in context
International Nuclear Information System (INIS)
Bernstein, S.
2000-10-01
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

Nyboer, J.; Rivers, N.; Muncaster, K.; Bennett, M.; Bennett, S.
2004-10-01
This paper provides a comprehensive database of renewable energy facilities in Canada by province and by resource type. It considers technologies used for power generation or cogeneration, renewable energy heating systems, hydrogen generation and transportation fuels. Renewable energy technologies convert naturally regenerating resources into useful energy such as electricity, thermal energy, hydrogen or bio-fuels. The database contains information on renewable power operations in Canada over a scale of 100 kilowatts of rated capacity. Smaller applications have been included for run-of-river, hydro, earth, wind and solar power. There are 753 records for renewable energy facilities in Canada, including wind, hydroelectricity, wood residue biomass, landfill/sewage gas, solar photovoltaic, municipal solid waste, and tidal energy. The data in this report was acquired from Statistics Canada and other public information sources. For each of the 753 renewable energy power plants, this report states its type of renewable energy, the province, the name of the project, its location, its operator, electrical generating capacity, number of generating units, average annual electricity production, and the year it began operation. Canada currently has an installed electrical capacity of 115 GW, of which renewable energy sources constitute 76 per cent with the dominant source being hydroelectricity. Manitoba has the highest portion of renewable energy in its installed electrical capacity. Approximately 40 per cent Canada's renewable power capacity is in Quebec, followed by 15 per cent in British Columbia. Nova Scotia has Canada's only tidal power plant. Most of the installed renewable energy power capacity in Canada is owned by integrated electric utilities and a small percentage is owned by renewable electricity generating companies, aluminium companies, pulp and paper companies or diversified electricity generators. It is expected that interest in renewable energy will grow with

Use of Fibrates in the United States and Canada
Jackevicius, Cynthia A.; Tu, Jack V.; Ross, Joseph S.; Ko, Dennis T.; Carreon, Daniel; Krumholz, Harlan M.
2012-01-01
Context Interest in the role of fibrates has intensified with the publication of the negative ACCORD trial with fenofibrate, especially since the evidence for clinical outcomes benefit for fibrates is heavily weighted on older fibrates, gemfibrozil and clofibrate. Objective This study seeks to examine trends in the current use of fibrates, and for fenofibrate, to illuminate the relationship between differences in the availability of proprietary versus generic formulations and use and economic implications in the United States (US) compared with Canada. Design/Setting/Patients Population-level, cohort study using IMS Health data in the United States and Canada of patients prescribed fibrates between 2002 and 2009. Main Outcome Measure(s) Fibrate prescribing and expenditures. Results From 2002–2009, fibrate prescriptions increased 117.1% in the US, by 12,000/month to 2.1 million prescriptions/month, yet only increased by 18.1% in Canada. (pCanada, while in the US, it increased by 159.3%, comprising 47.9% of total fibrate prescriptions in 2002 and 65.2% in 2009. The annual ratio of generic:brand fenofibrate use in the US from 2002 to 2008 ranged from 0:1 to 0.09:1, while the ratio in Canada steadily increased from 2005 to 2008 from 0.51:1 to 1.89:1. In the US, crude fenofibrate expenditures rose from $33.2 million/month in 2002 to $129.6 million/month in 2009, while those in Canada declined from $5.6 million/month to $5.1 million/month. Fibrate expenditures per 100,000 population were 3-fold higher in the US compared with Canada in 2009. Conclusions During the past decade, prescriptions for fibrates, particularly, fenofibrate, increased in the United States, while prescriptions for fibrates in Canada remained stable. PMID:21427374

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)

Canada as an energy superpower : how clean, how powerful, how super?
International Nuclear Information System (INIS)
Cleland, M.
2007-01-01
In 2006, Canada's Prime Minister declared Canada to be an emerging energy superpower due to its vast reserves of oil, gas, and uranium. This article clarified the attributes of a superpower and explained how they can be used to evaluate Canada's situation. The attributes of a superpower include a capability to potentially influence the behaviour of other countries and the course of world events; the capacity to deploy that capability when it can be effective; a clear understanding of one's national interests and policies; and, a will to use the energy capacity when called upon. This framework was used to test the hypothesis of Canada as a power in energy. It was agreed that in terms of reserves, production and exports, Canada is a significant player by world standards. Canada has technological leadership in some parts of the fuel cell industry, possibly nuclear energy and the deployment of advanced technology in resource extraction. However, it was argued that deployment capacity must be maintained and enhanced. The author claimed that Canada's ability to exercise power through unilateral deployment of energy resources is modest, although Canada does have an implicit policy expressed through international treaties such as its membership in the World Trade Organization (WTO), International Energy Agency (IEA), and the North American Free Trade Agreement (NAFTA). Canada also benefits from pipeline and powerline regulations for shared regulation of electricity reliability. It was suggested that Canada has the capability to be a voice in support of market-based approaches to energy and an open international trade and investment regime. It was determined that Canada is committed to market-based energy policies and to North American partnership in a broader international context. The author suggested that although Canada has many capabilities regarding energy resources and the capacity to deliver them to markets, it lacks energy policy at the national level, and requires

Habitat Evaluation Procedures (HEP) Report; Gamblin Lake, Technical Report 2005.
Energy Technology Data Exchange (ETDEWEB)
Entz, Ray
2005-05-01
On August 12, 2003, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the Gamblin Lake property, an acquisition completed by the Kalispel Tribe of Indians in December 2002. Evaluation species and appropriate models include bald eagle, black-capped chickadee, mallard, muskrat, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The Gamblin Lake Project provides a total of 273.28 Habitat Units (HUs) for the species evaluated. Conifer forest habitat provides 127.92 HUs for bald eagle, black-capped chickadee, mallard, and white-tailed deer. Forested wetland habitat provides 21.06 HUs for bald eagle, black-caped chickadee, mallard, and white-tailed deer. Wet meadow provides 78.05 HUs for Canada goose and mallard. Emergent wetland habitat provides 46.25 HUs for mallard, muskrat, and Canada goose. The objective of using HEP at the Gamblin Lake Project and other protected properties is to document the quality and quantity of available habitat for selected wildlife species. In this way, HEP provides information on the relative value of the same area at future points in time so that the effect of management activities on wildlife habitat can be quantified. When combined with other tools, the baseline HEP will be used to determine the most effective on-site management, restoration, and enhancement actions to increase habitat suitability for targeted species. The same process will be replicated every five years to quantitatively evaluate the effectiveness of management strategies in improving and maintaining habitat conditions while providing additional crediting to BPA for enhanced habitat values.

Canada-United States oil and gas relations, 1958 to 1974
Nemeth, Tammy Lynn
While there were overtures from each country to develop a more formal accord to govern the trade of oil and natural gas at different times since 1958, Canada rejected that option in 1974 when it decided to phase out oil exports to the U.S. The main purpose of this research is to trace the development and evolution of Canada-U.S. oil and gas relations from the beginning of the informal continental relationship in 1959, through attempts to formalize a continental oil and gas agreement in the late 1960s, to the initial reversal of continentalism by Canada in 1974. This study examines and compares the changing influence of the explanatory variables of interest groups, international forces, national security, economics, ideas, and personalities on the energy decision- and policy-making processes of Canada and the U.S. between 1958 and 1974. Four key decisions or events that can be considered turning points in the Canada-U.S. oil and gas relationship are analysed and include: Canada's exemption to the American Mandatory Oil Import Program (MOIP); Canada's National Oil Policy (NOP); the near revocation of Canada's MOIP exemption; and Canada's decision to phase out oil exports. These events and relationships are situated in the larger context of interdependence, intergovernmental and transgovernmental relations, and the altered bureaucratic structures of governments in both countries over this period of time. Although decisions concerning Canada-U.S. oil and gas relations, and the pursuit and reversal of continentalist policies, were influenced by concerns regarding the pressure of various interest groups, international forces, national security, and changing economic and ideological circumstances; in the period examined here, the personalities of and personal relationships between Presidents and Prime Ministers, and the actions of key officials, as well as their transgovernmental networks across the border, often made the difference in determining what policy or approach

Carbon dioxide for enhanced oil recovery in Canada
Energy Technology Data Exchange (ETDEWEB)
McDonald, S.; Manbybura, F.; Sparks, N.
1985-01-01
This paper examines the potential for carbon dioxide as a major miscible solvent in Canada and describes Shell Canada's carbon dioxide exploration efforts over the last few years. Enhanced oil recovery, specifically miscible flooding, has been recognized as a technically and economically feasible method for adding reserves and productive capacity to Canada's light and medium oil. The fiscal regime has been altered by both the federal and provincial governments to encourage miscible flooding development. As a result many projects have been initiated with others being evaluated and designed. This paper analyzes the history and the direction of miscible flooding in the United States, where carbon dioxide is becoming the predominant miscible solvent. The potential for future use of carbon dioxide in Canada is specifically addressed: potential oil recovery solvent supply, and economics. Shell's carbon dioxide exploration play currently underway is also discussed.

Climate prosperity, parallel paths: Canada-U.S. climate policy choices
International Nuclear Information System (INIS)
2011-01-01
The National Round Table on the Environment and the Economy (NRTEE) has conducted a study on the economic risks and opportunities of climate policies for Canada in the Canada-United States relationship background. This research aims to inform future policy decisions and provide ideas on means to serve Canadian interests in the context of this climate changing world. The NRTEE's research presented in this report focuses on the economic and environmental implications for Canada of harmonizing with the U.S. on climate policy. The document follows two main objectives: evaluate the consequences of U.S. climate policy choices for Canada and identify the policy options that would lead to a long-term reduction of emissions, taking into account the economic risks associated to policy choices in the U.S. and in Canada. According to the NRTEE, the government of Canada should take under consideration the benefits of the implementation of its own strategy for harmonization. This document provides a path leading to the achievement of a climate policy harmonization with the United States. 52 refs., 18 tabs., 24 figs.

Vegetation response to climate change : implications for Canada's conservation lands
International Nuclear Information System (INIS)
Scott, D.; Lemieux, C.
2003-01-01
Studies have shown that Canada's national parks are vulnerable to the impacts of climate change. A wide range of biophysical climate change impacts could affect the integrity of conservation lands in each region of Canada. This report examines the potential impact of climate change on landscape alterations and vegetation distribution in Canada's wide network of conservation lands. It also presents several ways to integrate climate change into existing conservation policy and adaptation strategies. Canada's conservation lands include provincial parks, migratory bird sanctuaries, national wildlife areas and wildlife protected areas. This is the first study to examine biome changes by applying an equilibrium Global Vegetation Model (GVM) to Canada's network of national park systems. Some of the policy and planning challenges posed by changes in landscape level vegetation were also addressed. The report indicates that in terms of potential changes to the biome classification of Canada's national forests, more northern biomes are projected to decrease. These northern biomes include the tundra, taiga and boreal conifer forests. 56 refs., 8 tabs., 6 figs

Malone, Alexandra; Mitrovic, Milenka; Grant, Andrea
2010-09-15
Carbon capture and storage (CCS) is a critical technology for Canada to make meaningful emissions reductions in the fossil fuels sector. Canada is a global leader in CCS, and both federal and provincial governments are taking action to advance the deployment of this technology, including allocating over CAD 3.5 billion in public funding to CCS. These investments support several interdependent initiatives focusing on addressing the challenges facing CCS, supporting innovation, accelerating deployment, and facilitating information sharing. Canada is also committed to working internationally to ensure that our efforts at home contribute to the overall global advancement of CCS.

Many mule duck and Cherry Valley duck flocks in different duck-producing regions of China have shown signs of an apparently new disease designated "short beak and dwarfism syndrome" (SBDS) since 2015. The disease is characterized by dyspraxia, weight loss, a protruding tongue, and high morbidity and low mortality rates. In order to characterize the etiological agent, a virus designated SBDSV M15 was isolated from allantoic fluid of dead embryos following serial passage in duck embryos. This virus causes a cytopathic effect in duck embryo fibroblast (DEF) cells. Using monoclonal antibody diagnostic assays, the SBDSV M15 isolate was positive for the antigen of goose parvovirus but not Muscovy duck parvovirus. A 348-bp (2604-2951) VP1gene fragment was amplified, and its sequence indicated that the virus was most closely related to a Hungarian GPV strain that was also isolated from mule ducks with SBDS disease. A similar disease was reproduced by inoculating birds with SBDSV M15. Together, these data indicate that SBDSV M15 is a GPV-related parvovirus causing SBDS disease and that it is divergent from classical GPV isolates.

Millar, R.H.G.
1996-01-01
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

Hard choices : climate change in Canada
Energy Technology Data Exchange (ETDEWEB)
Coward, H.; Weaver, A.J. (eds.)
2004-07-01
This book explains the nature of climate change, the options to respond to it and the virtues of Canada's commitment to the Kyoto Protocol. It includes a collection of essays by prominent Canadian scientists and scholars who discuss the impacts of climate change on Canada from physical, social, technological, economic and political perspectives. Climate change assessments have been made possible by monitoring and recording changes in atmospheric concentrations of greenhouse gases. As a result of these assessments, climate change has become an issue on policy agendas. Advanced computer models have convinced much of the scientific community that climate change will bring with it droughts, floods, hurricanes, forest fires, ice storms, blackouts, and increased warming in countries in high latitudes, including Canada, despite remaining uncertainties about how human activities will affect the climate. The authors cautioned that climate change response strategies can only be refined once these uncertainties are significantly reduced. refs., tabs., figs.

Canada's potential role in the Clean Development Mechanism
International Nuclear Information System (INIS)
Pape-Salmon, A.
2000-01-01
The role that Canada might play in the Kyoto Protocol's Clean Development Mechanism (CDM) is discussed. The CDM prescribes the way in which industrialized countries could create emission reduction credits for greenhouse gas emission reduction projects in developing countries which, in turn they could use to meet their own commitments and possibly reduce their cost of compliance with the Kyoto Protocol. While Canada does not see itself as a CDM project investor, it strongly supports private sector involvement in the CDM and believes that it has a role to play in assisting CDM investments by the Canadian private sector by facilitating desirable outcomes via international negotiations on the rules and modalities for the CDM which would minimize transaction costs; give prominence to aspects that Canada recognizes as necessary precursors to mobilizing private sector involvement in CDM activities; maximize the flexibility for use of the CDM; allow for conversion of credits between different Kyoto Mechanisms; allow for the certification of emissions sequestration from sinks; and maximize the environmental and sustainable development benefits of CDM projects. Canada also supports, along with the other members of the 'Umbrella group', the fewest possible restrictions and significant autonomy to the private sector to implement a variety of project activities in developing countries. This report provides a detailed examination of the Canadian government's views on the CDM, Canada's participation in international emission reduction projects, the factors that drive Canadian demand for greenhouse gas emission reduction offsets and the potential demand for CDM offsets, Canada's greenhouse gas emission inventory and projections, the approach of Canadian corporate investors in the CDM and Canadian technology and expertise in greenhouse gas emission reductions. Various appendices to the report contain further details on a number of cooperation agreements between Canada and other

Uranium in Canada: 1984 assessment of supply and requirements
International Nuclear Information System (INIS)
1985-09-01
The success of uranium exploration efforts in Canada has continued, resulting in an overall increase in domestic uranium resource estimates for the principal resource categories. In 1984, Canada's five primary uranium producers employed some 5,800 people at their mining and milling operations, and produced concentrates containing some 11 170 tU. In 1984 the resource estimates were (in tonnes U recoverable): measured - 54 000; indicated - 233 000; inferred - 264 000. Canada's projected annual primary uranium production capability will stabilize at some 12 000 tU through the remainder of the 1980s. Should market conditions warrant, additional production centres could be developed to raise production capability to a level of 15 000 tU by the latter half of the 1990s. Prognosticated resources exploitable at uranium prices of $300/kg U or less are estimated to amount to 292 000 tU. Speculative resources of interest at prices of $300/kg U or less, in areas assessed during 1984, are thought to total approximately one million tU. Uranium exploration expenditures in Canada in 1983 and 1984 were an estimated $41 and $35 million, respectively. Exploration drilling and surface development drilling in 1983 and 1984 were reported to be 153 000 m and 197 000 m, respectively, some 85 per cent of which was in Saskatchewan. 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 in Canada that are either in operation now or committed or expected to be in-service by 1995. Over the longer term, there is significant potential for discovering additional uranium resources in Canada

Placebo Trends across the Border: US versus Canada.
Harris, Cory S; Campbell, Natasha K J; Raz, Amir
2015-01-01
Physicians around the world report to using placebos in a variety of situations and with varying degrees of frequency. Inconsistent methodologies, however, complicate interpretation and prevent direct comparisons across studies. While US- and Canada-based physicians share similar professional standards, Canada harbours a less-litigious universal healthcare model with no formal placebo-related policy-factors that may impact how physicians view and use placebos. To compare American and Canadian data, we circulated an online survey to academic physicians practicing in Canada, collected anonymous responses, and extracted those of internists and rheumatologists for comparison to US data obtained through parallel methodologies. Whereas our data show overall concordance across the border-from definitions to ethical limitations and therapeutic potential-differences between American- and Canadian-based placebo practices merit acknowledgement. For example, compared to 45%-80% among US-based respondents, only 23±7% of Canada-based respondents reported using placebos in clinical practice. However, 79±7% of Canada-respondents-a figure comparable to US data-professed to prescribing at least one form of treatment without proven or expected efficacy. Placebo interventions including unwarranted vitamins and herbal supplements (impure placebos) as well as sugar pills and saline injections (pure placebos) appear more common in Canada, where more doctors described placebos as "placebos" (rather than "medications") and used them as a "diagnostic" tool (rather than a means of placating patient demands for treatment). Cross-border variation in the use of clinical placebos appears minor despite substantial differences in health care delivery system, malpractice climate, and placebo-related policy. The prevalence of impure placebos in both Canadian and US clinics raises ethical and practical questions currently unaddressed by policy and warranting investigation.

Restructuring of Canada's nuclear utilities: recent developments
International Nuclear Information System (INIS)
Guindon, S.
1998-01-01
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.

Anon.
1995-01-01
The position of Environment Canada in banning the export of PCB waste to the United States was defended as falling within their jurisdiction under provisions of the the Canadian Environmental Protection Act. The United States had previously banned the import of Canadian PCBs, but when it reversed its decision Environment Canada posted an Interim Order, upholding the ban. The decision to do so was based on protection of the large investment that was made to develop the Canadian PCB incineration facility in Swan Lake, Alberta. Canada also had an obligation under the Basel Convention to reduce it cross boundary movement of hazardous waste and provide adequate destruction facilities in Canada. Legal implications of PCB exports and the uncertainty of continuing access to American facilities were also cited as reasons for issuing the Interim Order

Evolution of thoracic surgery in Canada.
Deslauriers, Jean; Pearson, F Griffith; Nelems, Bill
2015-01-01
Canada's contributions toward the 21st century's practice of thoracic surgery have been both unique and multilayered. Scattered throughout are tales of pioneers where none had gone before, where opportunities were greeted by creativity and where iconic figures followed one another. To describe the numerous and important achievements of Canadian thoracic surgeons in the areas of surgery for pulmonary tuberculosis, thoracic oncology, airway surgery and lung transplantation. Information was collected through reading of the numerous publications written by Canadian thoracic surgeons over the past 100 years, interviews with interested people from all thoracic surgery divisions across Canada and review of pertinent material form the archives of several Canadian hospitals and universities. Many of the developments occurred by chance. It was the early and specific focus on thoracic surgery, to the exclusion of cardiac and general surgery, that distinguishes the Canadian experience, a model that is now emerging everywhere. From lung transplantation in chimera twin calves to ex vivo organ preservation, from the removal of airways to tissue regeneration, and from intensive care research to complex science, Canadians have excelled in their commitment to research. Over the years, the influence of Canadian thoracic surgery on international practice has been significant. Canada spearheaded the development of thoracic surgery over the past 100 years to a greater degree than any other country. From research to education, from national infrastructures to the regionalization of local practices, it happened in Canada.

Reinventing primary care: lessons from Canada for the United States.
Starfield, Barbara
2010-05-01
Canada is, in many respects, culturally and economically similar to the United States, and until relatively recently, the two countries had similar health systems. However, since passage of the Canada Health Act in the 1970s, that nation's health statistics have become increasingly superior. Although the costs of Canada's health system are high by international standards, they are much lower than U.S. costs. This paper describes several factors likely to be responsible for Canada's better health at lower cost: universal financial coverage through a so-called single payer; features conducive to a strong primary care infrastructure; and provincial autonomy under general principles set by national law.

Ocean Networks Canada's "Big Data" Initiative
Dewey, R. K.; Hoeberechts, M.; Moran, K.; Pirenne, B.; Owens, D.
2013-12-01
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

Estimates of Canada's uranium resources for 1982 remained essentially unchanged from those of 1980. However, the economic conditions facing the industry have changed greatly during the past few years as production costs continued to rise without corresponding increases in uranium prices. As a result, a smaller portion of Canada's uranium resources is of current economic interest. Total resources amount to 573 000 tonnes of uranium. Just over 10% of this uranium will be required domestically during the next 30 years to fuel the more than 15 000 megawatts of nuclear power capacity now operating or committed for operation in Canada by 1993. In 1982 seven uranium producers in Canada, directly employing 4800 people, produced concentrates containing 8075 tonnes of uranium. Based on currently committed expansion plans, Canada's projected annual production capability could grow to some 12 000 tonnes of uranium by 1986. Canadian producers shipped 7643 tonnes of uranium valued at some $838 millon in 1982. As of January 1, 1983, outstanding uranium export commitments amounted to 60 000 tonnes or roughly 10% of the total Canadian uranium resources mentioned above. Japan has been Canada's most important single customer in the past decade, receiving about 34% of Canada's total exports since 1972. Most of the remaining exports have gone to the European Economic Community (33%), other countries in Western Europe (18%), and the United States (15%). Substantial efforts in uranium exploration that have been continued, especially in northern Saskatchewan, where two-thirds of the $71 million total exploration expenditures of 1982 were incurred. This continued effort has led to the discovery of a number of important deposits over the past few years which could be developed if market conditions improve. It is estimated that total Canadian production capability could reach 15 000 tonnes of uranium annually by the mid-1990s

Economic evaluations should form part of the basis for public health decision making on new vaccine programs. While Canada's national immunization advisory committee does not systematically include economic evaluations in immunization decision making, there is increasing interest in adopting them. We therefore sought to examine the extent and quality of economic evaluations of vaccines in Canada. We conducted a systematic review of economic evaluations of vaccines in Canada to determine and summarize: comprehensiveness across jurisdictions, studied vaccines, funding sources, study designs, research quality, and changes over time. Searches in multiple databases were conducted using the terms "vaccine," "economics" and "Canada." Descriptive data from eligible manuscripts was abstracted and three authors independently evaluated manuscript quality using a 7-point Likert-type scale scoring tool based on criteria from the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). 42/175 articles met the search criteria. Of these, Canada-wide studies were most common (25/42), while provincial studies largely focused on the three populous provinces of Ontario, Quebec and British Columbia. The most common funding source was industry (17/42), followed by government (7/42). 38 studies used mathematical models estimating expected economic benefit while 4 studies examined post-hoc data on established programs. Studies covered 10 diseases, with 28/42 addressing pediatric vaccines. Many studies considered cost-utility (22/42) and the majority of these studies reported favorable economic results (16/22). The mean quality score was 5.9/7 and was consistent over publication date, funding sources, and disease areas. We observed diverse approaches to evaluate vaccine economics in Canada. Given the increased complexity of economic studies evaluating vaccines and the impact of results on public health practice, Canada needs improved, transparent and consistent processes

Oil Production, Refining and Transportation in Canada
Directory of Open Access Journals (Sweden)
Igbal A. Guliyev
2015-01-01
Full Text Available The article deals with fuel and energy complex of Canada as one of the largest manufacturers of primary energy in the world, which provides up to 6 percent of the world energy supply. Only the Russian Federation, PRC, the United States of America and the Kingdom of Saudi Arabia have larger production volumes. However, oil plays the most significant role in Canada's energy exports. It is estimated that its proven reserves are sufficient to meet the demand for 140 years at current production rate. The relevance of the study, including the analysis of fuel and energy complex of Canada, is due to the fact that such comparison and synthesis of data on the amount of recoverable oil reserves, the volume of its production, imports, exports and transit of oil and oil products, the distribution of oil for transportation (via pipelines, rail, sea, road, strategic oil field, refining and transportation of oil and oil products development projects, as well as implementation of Canada's best practices in the Russian Federation, is being developed for the first time. In addition, the data given in previously published articles on the subject, due to the dynamic development of the industry, are obsolete and do not reflect the real situation.

Education of advanced practice nurses in Canada.
Martin-Misener, Ruth; Bryant-Lukosius, Denise; Harbman, Patricia; Donald, Faith; Kaasalainen, Sharon; Carter, Nancy; Kilpatrick, Kelley; DiCenso, Alba
2010-12-01
In Canada, education programs for the clinical nurse specialist (CNS) and nurse practitioner (NP) roles began 40 years ago. NP programs are offered in almost all provinces. Education for the CNS role has occurred through graduate nursing programs generically defined as providing preparation for advanced nursing practice. For this paper, we drew on pertinent sections of a scoping review of the literature and key informant interviews conducted for a decision support synthesis on advanced practice nursing to describe the following: (1) history of advanced practice nursing education in Canada, (2) current status of advanced practice nursing education in Canada, (3) curriculum issues, (4) interprofessional education, (5) resources for education and (6) continuing education. Although national frameworks defining advanced nursing practice and NP competencies provide some direction for education programs, Canada does not have countrywide standards of education for either the NP or CNS role. Inconsistency in the educational requirements for primary healthcare NPs continues to cause significant problems and interferes with inter-jurisdictional licensing portability. For both CNSs and NPs, there can be a mismatch between a generalized education and specialized practice. The value of interprofessional education in facilitating effective teamwork is emphasized. Recommendations for future directions for advanced practice nursing education are offered.

Canada's nuclear achievement. Technical and economic perspectives
International Nuclear Information System (INIS)
Rummery, T.E.; Macpherson, J.A.
1995-01-01
Canada's leading role and eminent accomplishments in nuclear development now span more than half a century. They encompass aspects as diverse as the design and sale of nuclear power reactors and research reactor technology, to the establishment of a corps of scientists, engineers and technologists with the expertise to address a wide scope of important nuclear science issues. The success of a country of modest technical and financial resources, like Canada, in the highly technical and very competitive nuclear field is surprising to many Canadians, and does not fit the usual image we have of ourselves as 'drawers of water and hewers of wood'. For this reason alone, Canada's nuclear achievement makes an interesting and timely story. To address the many facets of Canada's nuclear activities over the past 50 years would obviously require space far beyond that available in this paper. We have therefore limited this review to highlights we judge to be the most pertinent and interesting from an historical, technical and economic perspective. We also indicate briefly our view of the future of nuclear power in the overall context of energy needs in a world that is becoming more industrial and increasingly environmentally conscious.

Petro-Canada fined $290,000 for spill
International Nuclear Information System (INIS)
Reid, W.
2006-01-01
Petro-Canada has recently received the largest fine of its kind in Atlantic Canada history for polluting seas around the Terra Nova oilfield. The $290,000 fine was handed down a month after a separate incident during which a flash fire on a tanker killed a crew member. The spill occurred on Petro-Canada's Terra Nova vessel, and was the result of a malfunctioning separator, which caused 165,000 litres of petroleum to leak into the ocean. Concerns had been voiced about the separator months prior to the spill. At the time of the leak, periodic alarms in the control room were attributed to weather, production flow rates and vessel motion, as routine water tests 2 hours earlier had shown that everything was normal. Terra Nova is located 350 km east of St. John's, Newfoundland in an environmentally sensitive area. After the spill, the firm immediately shut down operations and commenced an environmental clean-up and monitoring procedure costing more than $3 million. The separator has been repaired. Petro-Canada and the Crown prosecutor have proposed that $120,000 of the fine should be donated to the federal Environmental Damages Fund, with an additional $100,000 to be set up as an environmental sciences scholarship. 1 fig

Petro-Canada annual report, 1993
International Nuclear Information System (INIS)
1994-02-01
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. A financial review from 1986 to the present is included, along with a glossary of financial terms, a financial statement, and a 5-year summary. Reserves information comparing the current to the previous year are given. 2 figs., 12 tabs

Natural gas potential in Canada
International Nuclear Information System (INIS)
1997-01-01
An independent assessment of the undiscovered gas potential in Canada was conducted by a group of volunteer geoscientists. This report is the first of a series of assessments that are planned to be issued every three to four years. Separate assessments were made of conventional gas resources, unconventional gas resources and frontier gas resources. The assessment for conventional gas resources was organized into three categories: (1) gas producing areas where new discoveries can be integrated into existing producing and transportation infrastructure, (2) frontier basins where gas discoveries have been made, but no production is currently underway, and (3) frontier areas where gas-containing sedimentary rocks are known to exist, but where no gas discoveries have been made to date. The committee used year-end 1993 reserves data from discovered pools in each exploration play to predict the undiscovered potential. Information about discovered pools, geological setting, geographic limits and pool sizes of undiscovered pools in each exploration play was provided. Results of the investigation led to the conclusion that the natural gas potential in Canada is in fact larger than hitherto expected. It was estimated that in the Western Canada Sedimentary Basin 47 per cent of the total volume of conventional gas is yet to be discovered. 152 figs

McKenna, Janis
2012-10-01
Here we are in the 21st century in Canada, where most of us would say that young girls and boys have equal access to education, opportunities, and careers of their own choice. In Canada, women currently outnumber men in full-time university enrollment, in Medical Schools and in Law Schools. 48% of the Canadian work force is female, yet women make up only 21% of working professionals in science, engineering and technology. Canada-wide in Physics, the situation is such that only 20% of our BSc graduates are women, and 19% of our PhD graduates are women. It is evident that the ``leaky pipeline'' in Physics leaks most at a young age, before BSc graduation. High school physics statistics in BC indicate that while most of the grade 12 science and math disciplines have roughly equal numbers of young men and women enrolled, this is not the case for high school physics, where province-wide, only 30% of Physics 12 students are women. (Biology is also skewed, but in the other direction: 62% of Biology 12 students are women) This poster will present current statistics and will hopefully be a wake-up call for us all to consider participating in more outreach in science, and especially physics, in our high schools.

Indigenous Educational Attainment in Canada
Directory of Open Access Journals (Sweden)
Catherine E. Gordon
2014-06-01
Full Text Available In this article, the educational attainment of Indigenous peoples of working age (25 to 64 years in Canada is examined. This diverse population has typically had lower educational levels than the general population in Canada. Results indicate that, while on the positive side there are a greater number of highly educated Indigenous peoples, there is also a continuing gap between Indigenous and non-Indigenous peoples. Data also indicate that the proportion with less than high school education declined, which corresponds with a rise of those with a PSE; the reverse was true in 1996. Despite these gains, however, the large and increasing absolute numbers of those without a high school education is alarming. There are intra-Indigenous differences: First Nations with Indian Status and the Inuit are not doing as well as non-Status and Métis peoples. Comparisons between the Indigenous and non-Indigenous populations reveal that the documented gap in post-secondary educational attainment is at best stagnant. Out of the data analysis, and based on the history of educational policy, we comment on the current reform proposed by the Government of Canada, announced in February of 2014, and propose several policy recommendations to move educational attainment forward.

Fisheries and Oceans Canada - habitat management program in Ontario
Energy Technology Data Exchange (ETDEWEB)
NONE
2011-07-01
On May 5, 2011, the Ontario Waterpower Association hosted the emergent hydro workshop in Peterborough. In the course of the workshop, Fisheries and Oceans Canada presented the habitat management program in Ontario. Fisheries and Oceans Canada explained that their role is to protect water resources. The Fisheries Act was passed to manage fisheries and fish habitats in Canada and to protect them from harmful alteration, disruption or destruction. The policy for the management of fish was written to interpret the Fisheries Act and enhance the productive capacity of fish habitats. In addition, two other Acts were passed, the Species at Risk Act and the Canadian Environmental Assessment Act, designed to protect species from extinction and improve coordination of, and public access to EA information. This presentation highlighted the different existing policies aimed at protecting fisheries and fish habitats in Canada.

Hydropower, an integral part of Canada's climate change strategy
International Nuclear Information System (INIS)
Fortin, P.
1999-01-01
The development and implementation of a climate change policy could be among the most far-reaching environmental initiatives ever embarked upon in Canada and abroad. If Canada is to stabilize or reduce its Greenhouse Gas (GHG) emissions over the long term, a significant adjustment to Canadian industry will be required as we move away from fossil fuel-intensive and GHG producing activities. Future hydroelectric projects provide Canada with a unique opportunity to significantly reduce the costs associated with stabilizing its GHG emissions. In addition, the energy storage and dispatchability associated with hydropower can support development of other low emitting renewable resources such as wind and solar. This document discusses the potential role of hydropower as a tool to reduce emissions, recommends action to reduce barriers facing hydropower and comments on some of the policy tools available to manage Canada's GHG emissions.

Placebo Trends across the Border: US versus Canada
Harris, Cory S.; Campbell, Natasha K. J.; Raz, Amir
2015-01-01
Background Physicians around the world report to using placebos in a variety of situations and with varying degrees of frequency. Inconsistent methodologies, however, complicate interpretation and prevent direct comparisons across studies. While US- and Canada-based physicians share similar professional standards, Canada harbours a less-litigious universal healthcare model with no formal placebo-related policy—factors that may impact how physicians view and use placebos. Methods To compare American and Canadian data, we circulated an online survey to academic physicians practicing in Canada, collected anonymous responses, and extracted those of internists and rheumatologists for comparison to US data obtained through parallel methodologies. Results Whereas our data show overall concordance across the border—from definitions to ethical limitations and therapeutic potential—differences between American- and Canadian-based placebo practices merit acknowledgement. For example, compared to 45%-80% among US-based respondents, only 23±7% of Canada-based respondents reported using placebos in clinical practice. However, 79±7% of Canada-respondents—a figure comparable to US data—professed to prescribing at least one form of treatment without proven or expected efficacy. Placebo interventions including unwarranted vitamins and herbal supplements (impure placebos) as well as sugar pills and saline injections (pure placebos) appear more common in Canada, where more doctors described placebos as “placebos” (rather than “medications”) and used them as a “diagnostic” tool (rather than a means of placating patient demands for treatment). Interpretation Cross-border variation in the use of clinical placebos appears minor despite substantial differences in health care delivery system, malpractice climate, and placebo-related policy. The prevalence of impure placebos in both Canadian and US clinics raises ethical and practical questions currently unaddressed

Canada's energy perspectives and policies for sustainable development
International Nuclear Information System (INIS)
Hofman, Karen; Li Xianguo
2009-01-01
A regression analysis is performed to make projections for the Canadian energy production and consumption. These have been increasing and are projected to increase even further in the near future. The primary energy production and consumption are projected to increase by 52% and 34%, respectively, by 2025 over 2004 if business as usual. The amount of fossil energy resources is finite and the extraction, transportation and combustion of fossil fuels cause environmental pollution and climate change. On the other hand, energy plays an important role in the economic and social development of Canada. Canada can develop further from an energy balance point of view, but this alone cannot be sustainable, because of the negative consequences of the major energy use on the environment. Application of energy localization and diversification is a promising solution, but in order to reach that, better energy efficiency and more use of renewable energy are necessary. Instead of non-compulsory policies Canada's policy approach should have more compulsory policies. Only then Canada can be made to develop further in a sustainable manner

Production of bio-synthetic natural gas in Canada.
Hacatoglu, Kevork; McLellan, P James; Layzell, David B
2010-03-15
Large-scale production of renewable synthetic natural gas from biomass (bioSNG) in Canada was assessed for its ability to mitigate energy security and climate change risks. The land area within 100 km of Canada's network of natural gas pipelines was estimated to be capable of producing 67-210 Mt of dry lignocellulosic biomass per year with minimal adverse impacts on food and fiber production. Biomass gasification and subsequent methanation and upgrading were estimated to yield 16,000-61,000 Mm(3) of pipeline-quality gas (equivalent to 16-63% of Canada's current gas use). Life-cycle greenhouse gas emissions of bioSNG-based electricity were calculated to be only 8.2-10% of the emissions from coal-fired power. Although predicted production costs ($17-21 GJ(-1)) were much higher than current energy prices, a value for low-carbon energy would narrow the price differential. A bioSNG sector could infuse Canada's rural economy with $41-130 billion of investments and create 410,000-1,300,000 jobs while developing a nation-wide low-carbon energy system.

Nuclear energy's continuing benefits to Canada
International Nuclear Information System (INIS)
Gray, J.L.
1981-06-01
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

Canada: variations on a common theme
Directory of Open Access Journals (Sweden)
Raisa B. Deber
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.

Transnational surrogacy: Canada's contradictions.
Lozanski, Kristin
2015-01-01
Transnational commercial surrogacy represents a form of medical tourism undertaken by intended parents who seek to hire women in other countries, increasingly often in the global South, as surrogates. While much of the scholarly literature focuses on the conditions of surrogacy within host countries, such as India, there has been limited analysis of transnational surrogacy focused upon origin countries. In this article, I build upon the scholarship that explores the impact of host country structures on transnational surrogacy, with special attention to the significance of Canadian citizenship policy through analysis of legislation and policy vis-à-vis transnational commercial surrogacy. The Canadian case demonstrates clear contradictions between the legislation and policy that is enacted domestically to prohibit commercial surrogacy within Canada and legislation and policy that implicitly sanctions commercial surrogacy through the straightforward provision of citizenship for children born of such arrangements abroad. The ethical underpinnings of Canada's domestic prohibition of commercial surrogacy, which is presumed to exploit women and children and to impede gender equality, are violated in Canada's bureaucratic willingness to accept children born of transnational commercial surrogacy as citizens. Thus, the ethical discourses apply only to Canadian citizens within Canadian geography. The failure of the Canadian government to hold Canadian citizens who participate in transnational commercial surrogacy to the normative imperatives that prohibit the practice within the country, or to undertake a more nuanced, and necessarily controversial, discussion of commercial surrogacy reinforces transnational disparities in terms of whose bodies may be commodified as a measure of gendered inequality.

Professional Decline and Resistance: The Case of Library and Archives Canada
Directory of Open Access Journals (Sweden)
Tami Oliphant
2014-05-01
Full Text Available In 2004, Canada was the first country in the world to amalgamate its two main documentary heritage institutions, the National Archives of Canada (established in 1872 and the National Library of Canada (established in 1953 into one "modernized" institution: Library and Archives Canada (LAC. The "modernization" policy has commercialized and reduced services, collections, and collaboration while simultaneously deprofessionalizing and casualizing the work of professionals. Resistance to modernization has come from many stakeholders across Canada but the responses by the Canadian Association of University Teachers (CAUT and the Canadian Library Association (CLA are particularly salient. Both are national organizations concerned with access to information and Canada’s documentary heritage. The case of LAC demonstrates how a neoliberal remaking of one prominent, national institution can weaken entire professions.

Bioethanol from lignocellulosics: Status and perspectives in Canada.
Mabee, W E; Saddler, J N
2010-07-01
Canada has invested significantly in the development of a domestic bioethanol industry, and it is expected that bioethanol from lignocellulosics will become more desirable to the industry as it expands. Development of the Canadian industry to date is described in this paper, as are examples of domestic research programs focused on both bioconversion and thermochemical conversion to generate biofuels from lignocellulosic biomass. The availability of lignocellulosic residues from agricultural and forestry operations, and the potential biofuel production associated with these residues, is described. The policy tools used to develop the domestic bioethanol industry are explored. A residue-based process could greatly extend the potential of the bioethanol industry in Canada. It is estimated that bioethanol production from residual lignocellulosic feedstocks could provide up to 50% of Canada's 2006 transportation fuel demand, given ideal conversion and full access to these feedstocks. Utilizing lignocellulosic biomass will extend the geographic range of the bioethanol industry, and increase the stability and security of this sector by reducing the impact of localized disruptions in supply. Use of disturbance crops could add 9% to this figure, but not in a sustainable fashion. If pursued aggressively, energy crops ultimately could contribute bioethanol at a volume double that of Canada's gasoline consumption in 2006. This would move Canada towards greater transportation fuel independence and a larger role in the export of bioethanol to the global market. Copyright 2009 Elsevier Ltd. All rights reserved.

A review of gasoline retailing Canada vs United States: Update, 1980-1990
International Nuclear Information System (INIS)
1992-10-01
A comparison is presented of the economies of scale achieved by the gasoline retailing sector in Canada and the United States over the period 1980-1990. Gasoline demand increased steadily in the USA and by 1990 was 10% higher than in 1980, while in Canada the fluctuating demand has led to a 12% decline for the same period. Number of automobiles increased 23% in Canada compared to 19% in the USA, while number of retail outlets fell by 5,000 in Canada and 47,000 in the USA. The average distance travelled by automobile increased 11% and 7%, respectively for Canada and the USA, however Canadians drove 7% further than Americans. In 1990, automobiles used ca 200 litres less fuel per year in Canada than the USA. Average sales per outlet increased by 56% in the USA and 10% in Canada. While most of the price difference between American and Canadian gasoline is attributable to taxes, the larger size of American refineries, transportation costs, product slate and product demand affects prices. 6 figs

Transatlantic Cooperation in Space: Eu-Canada Free Trade Agreement
Directory of Open Access Journals (Sweden)
Luise Weber-Steinhaus
2014-12-01
Full Text Available National governments are keenly aware of the need for investment in space. Canada, as a formal cooperating state in the European Space Agency (ESA, and Germany, as a leading member state of ESA, are interlinked in Europe’s space endeavours. Beyond ESA, Germany and Canada additionally have a strong history of bilateral cooperation on a range of space projects. This paper discusses the novel interdependencies between clear national and now supranational space policies, using the examples of the Canada-European Union (EU Comprehensive Economic and Trade Agreement (CETA. The agreement covers most aspects of the EU-Canada bilateral economic relationship and includes space. The paper focuses on international space policies, strategic bilateral co-operation, and technical accomplishments. It takes a closer look at German-Canadian collaboration in space programs and offers some reflection on the effect of both the EU and ESA’S transatlantic involvement in space.

Fusion energy and Canada's role
International Nuclear Information System (INIS)
Drolet, T.S.
1992-01-01
Fusion is the process of releasing energy from matter which occurs in our sun. Canada is contributing to the development of technology which will permit this process to be harnessed and made available on earth. The international effort has increased from a modest beginning in the 1950s to a level of approximately two billion dollars annually in the 1980s. The purpose of this booklet is to introduce the concept of fusion energy as a technology which should make an important addition to the mix of energy sources for our future. Through a co-ordinated approach, Canada has established several projects which will contribute significantly to the development of technologies in specific areas leading to opportunities now for Canadian industry in the international effort

Energy [R]Evolution: Opportunities for Decarbonizing Canada
Byrne, J. M.
2016-12-01
The future of conventional energy in Canada is uncertain. World oil prices have suffered steep declines recently and there are no strong arguments for recovery in the foreseeable future. The country is now engaged in serious debates and discussions over the value of GHG emissions, pipelines, oil and gas operations, and renewable energy. Oilsands deposits in northern Alberta require long-term investment and decades of consistent sales to repay those investments. The election of more progressive governments in Alberta and Canada may provide the national and global credibility and opportunity to address the environmental problems caused by Oilsands and other fossil fuel developments. The discussion will focus on the possible ways forward for Canada to diversify the regional and national economy with renewable energy networks, thereby meeting our Paris GHG emission reduction commitments. The end goal of this work is to see the Canadian economy decarbonized within two decades.

A review of existing renewable energy facilities in Canada
International Nuclear Information System (INIS)
Nyboer, J.; Pape-Salmon, A.
2003-05-01
This first annual report on renewable energy in the Canadian electricity sector includes records from 629 power plants across Canada. Renewable energy sources include wind, hydroelectricity, wood residue biomass, landfill/sewage gas, solar photovoltaic, municipal solid waste, and tidal energy. The data in this report was acquired from Statistics Canada and other public information sources. For each of the 629 renewable energy power plants, this report states its type of renewable energy, the province, the name of the project, its location, its operator, electrical generating capacity, number of generating units, average annual electricity production, and the year it began operation. The majority (64 per cent) of Canada's total installed power capacity comes from renewable energy sources, with the dominant source being hydroelectricity. Manitoba has the highest portion of renewable energy at almost 98 per cent of its installed electrical capacity. Nearly half of Canada's renewable power capacity is in Quebec, followed by 18 per cent in British Columbia. Nova Scotia has Canada's only tidal power plant. Approximately 80 per cent of the total installed renewable energy power capacity in Canada is owned by integrated electric utilities. Eleven per cent is owned by renewable electricity generating companies, 5 per cent is owned by aluminium companies, and 3 per cent is owned by pulp and paper companies. The rest is owned by diversified electricity generators. It is expected that with the ratification of the Kyoto Protocol interest in renewable energy will grow. 6 refs., 3 tabs., 2 figs., 1 appendix

A shared vision for energy in Canada
International Nuclear Information System (INIS)
2007-08-01
Energy plays an important role in Canadian society. With vast and diverse energy resources, Canada is a major participant in international energy markets. This report discussed the challenges and opportunities of Canada's energy sector, such as meeting the demand for energy; conserving and using existing energy more efficiently; developing new and innovative energy technologies; moving to renewable, greener and cleaner energy sources; improving transmission and transportation capacity; improving regulatory approval processes; and meeting demand for a skilled and available workforce. The report also discussed formalization of the role of provinces and territories in international energy discussions. A seven point action plan was also presented in order to provide concrete solutions and actions if the full potential of Canada's energy sector was to be achieved. These steps included promoting energy efficiency and conservation; accelerating the development and deployment of energy research and technologies that advance more efficient production, transmission and use of clean and conventional energy sources; facilitating the development of renewable, green and/or cleaner energy sources to meet future demand while contributing to environmental goals; and, developing and enhancing a modern, reliable, environmentally safe, and efficient series of transmission and transportation networks for domestic and export/import sources of energy. Other actions were also presented, such as improving the timeliness and certainty of regulatory approval decision-making processes while maintaining rigorous protection of the environment and public interest; developing and implementing strategies to meet energy-sector human resource needs now and into the future; and, pursuing formalized participation of provinces and territories in international discussions and negotiations on energy. It was concluded that immediate action and sustained effort by all is needed in order to ensure that all

The most abundant fossil fuel in Canada is coal, and almost 20 per cent of all electricity generated in Canada uses coal as its energy source. About 75 per cent of all electricity generated in Alberta and 67 per cent of that generated in Saskatchewan is derived from domestic coal resources. Coal plays an important role in regional economies. This paper was prepared with the intent of providing a status report on the coal industry to the Energy and Mines Ministers while also identifying the challenges facing the industry. Productivity has been increased and emissions have been reduced, but the industry is facing risks. Cooperation between industry players and governments is required to ensure the long-term viability of the coal industry in Canada. Some recommendations were made by the Coal Association of Canada (CAC) as follows: (1) that the 21 per cent tax-rate to the mining sector be extended by the federal government, while continuing deductibility of the existing resource allowance, (2) that the Corporate Capital Tax be eliminated entirely by the federal government, or that at least for all assets located in rural areas, and (3) the CAC believes better solutions than the Kyoto Protocol exist (CAC does not support Kyoto). The CAC is of the opinion that continental approach should be favored for the reduction of greenhouse gas emissions. The CAC also believes that financial and technical resources should be allocated for the improvement of existing infrastructure and the development of new technologies in terms of reductions of emissions. refs

Preparation and mounting of adult Drosophila structures in Canada balsam.
Stern, David L; Sucena, Elio
2012-03-01
The Drosophila cuticle carries a rich array of morphological details. Thus, cuticle examination has had a central role in the history of genetics. To prepare fine "museum-quality," permanent slides, it is best to mount specimens in Canada Balsam. It is difficult to give precise recipes for Canada Balsam, because every user seems to prefer a slightly different viscosity. Dilute solutions spread easily and do not dry too rapidly while mounting specimens. The disadvantage is that there is actually less Balsam in a "drop" of the solution, and when dried, it can contract from the sides of the coverslip, sometimes disturbing the specimen. Unfortunately, there is no substitute for experience when using Canada Balsam. This protocol describes a procedure for mounting adult cuticles in Canada Balsam.

Energy Technology Data Exchange (ETDEWEB)
1990-01-01
A summary is presented of Canada's Green Plan, a comprehensive action plan to ensure a healthy environment for the future. The plan defines targets and schedules which will drive federal environmental initiatives, and incorporates concepts of sustainable development. Elements of the plan include initiatives to combat and prevent water pollution; control ocean dumping; control smog-causing emissions; provide tighter air pollution standards; provide for sound waste management according to the principles of reduce, reuse, recycle, and recover; assess and control chemical wastes; sustain Canadian forests and maintain their diversity while shifting forest management from sustained yield to sustainable development; maintain and enhance environmental sustainability in the agro-food sector and the fishery sector; preserve and protect national parks and wildlife; and preserve and enhance the integrity, health, biodiversity and productivity of Arctic ecosystems. With respect to global-scale problems, measures will be taken to stabilize greenhouse gas emissions, limit acid rain-related emissions, and phase out the use of ozone-depleting substances. The plan also intends to improve Canada's capability to respond to environmental emergencies, improve environmental decision-making by strengthening and building of partnerships, promote environmental science research and development, and make effective and balanced use of enviromental laws, with market-based approaches for environmental protection.

Submarine landslides in Arctic sedimentation: Canada Basin
Mosher, David C.; Shimeld, John; Hutchinson, Deborah R.; Lebedova-Ivanova, N; Chapman, C.
2016-01-01
Canada Basin of the Arctic Ocean is the least studied ocean basin in the World. Marine seismic field programs were conducted over the past 6 years using Canadian and American icebreakers. These expeditions acquired more than 14,000 line-km of multibeam bathymetric and multi-channel seismic reflection data over abyssal plain, continental rise and slope regions of Canada Basin; areas where little or no seismic reflection data existed previously. Canada Basin is a turbidite-filled basin with flat-lying reflections correlateable over 100s of km. For the upper half of the sedimentary succession, evidence of sedimentary processes other than turbidity current deposition is rare. The Canadian Archipelago and Beaufort Sea margins host stacked mass transport deposits from which many of these turbidites appear to derive. The stratigraphic succession of the MacKenzie River fan is dominated by mass transport deposits; one such complex is in excess of 132,000 km2 in area and underlies much of the southern abyssal plain. The modern seafloor is also scarred with escarpments and mass failure deposits; evidence that submarine landsliding is an ongoing process. In its latest phase of development, Canada Basin is geomorphologically confined with stable oceanographic structure, resulting in restricted depositional/reworking processes. The sedimentary record, therefore, underscores the significance of mass-transport processes in providing sediments to oceanic abyssal plains as few other basins are able to do.

HISTORIOGRAPHIES ET FÉDÉRALISME AU CANADA
Directory of Open Access Journals (Sweden)
Xavier Dionne
2009-10-01
Full Text Available This article studies the historical representation of the two main national communities in Canada; that is, the English-Canadian and the French-Canadian.Throughout the history of the English Canadian community, one cansee an ambitious national project. The national construction of Canada suggests the existence of a neutral model of government but, when looking at this carefully, it is possible to see something quite different. English-speaking historians from Canada have normally introduced the concept of a unitary federalism as the most perfect form of the Canadian integration project. This integrating federalism, that does not lead to emancipation, stems from thecentralist views of John Macdonald, one of the fathers of Canadian federalism. This approach has been kept for over 140 years of common history and, to this date, continues to be one of the main obstacles for minority nations within Canada. To strengthen their thesis, the authors base their work on an extensive analysis exploring the three big strategies used by the central government to assert its authority on the member States of the Canadian Federation in the long term: using the judicial power, centralizing powers andglobalization. The strategies used have varied depending on the economic scenario, political leaders and the political power relations regarding the links between the Federation and the provinces.

Estimated Number of Birds Killed by House Cats (Felis catus in Canada
Directory of Open Access Journals (Sweden)
Peter Blancher
2013-12-01
Full Text Available Predation by house cats (Felis catus is one of the largest human-related sources of mortality for wild birds in the United States and elsewhere, and has been implicated in extinctions and population declines of several species. However, relatively little is known about this topic in Canada. The objectives of this study were to provide plausible estimates for the number of birds killed by house cats in Canada, identify information that would help improve those estimates, and identify species potentially vulnerable to population impacts. In total, cats are estimated to kill between 100 and 350 million birds per year in Canada (> 95% of estimates were in this range, with the majority likely to be killed by feral cats. This range of estimates is based on surveys indicating that Canadians own about 8.5 million pet cats, a rough approximation of 1.4 to 4.2 million feral cats, and literature values of predation rates from studies conducted elsewhere. Reliability of the total kill estimate would be improved most by better knowledge of feral cat numbers and diet in Canada, though any data on birds killed by cats in Canada would be helpful. These estimates suggest that 2-7% of birds in southern Canada are killed by cats per year. Even at the low end, predation by house cats is probably the largest human-related source of bird mortality in Canada. Many species of birds are potentially vulnerable to at least local population impacts in southern Canada, by virtue of nesting or feeding on or near ground level, and habitat choices that bring them into contact with human-dominated landscapes where cats are abundant. Because cat predation is likely to remain a primary source of bird mortality in Canada for some time, this issue needs more scientific attention in Canada.

Overview of Canada's uranium industry
International Nuclear Information System (INIS)
Lowell, A.F.
1982-06-01
This paper places Canada's uranium industry in its international context. Most uranium, except that produced in the United States, is traded internationally. A brief history of the industry worldwide is given to show how the principal producing areas have fared to date. The industry is young, highly cyclical, and still far from achieving stability. Uranium is a single end-use commodity, entirely dependent on the generation of electricity in nuclear stations, and is without price elasticity: lowering the price does not increase demand. The typical nuclear fuel processing chain has not encouraged or led to much vertical integration. Uranium is subject to more governmental control than any other commodity. The principal market is located in the industrial countries of western Europe, the United States, Canada, and the far east. The uranium supply-demand situation is reviewed, including the current and near-term oversupply and the longer term outlook to 1995. The major negative impact of reactor cancellations and deferments in the United States is discussed. Because of the difficulty in getting reactors on line, it has become easier to forecast the demand for uranium over the next 10 years. It is more difficult to predict how that demand will be met from the more than ample competing sources. Canada's potential for supplying a significant portion of this demand is considered in relation to producers and potential new producers in other countries

The state of genetically modified crop regulation in Canada
Smyth, Stuart J
2014-01-01
Genetically modified (GM) crops were first commercialized in Canada in 1995 and the 2014 crop represents the 20th year of successful production. Prior to the first commercialization of GM crops, Canada reviewed its existing science-based regulatory framework and adapted the existing framework to allow for risk assessments on the new technology to be undertaken in a timely and efficient manner. The result has been the rapid and widespread adoption of GM varieties of canola, corn and soybeans. The first decade of GM crop production precipitated 2 landmark legal cases relating to patent infringement and economic liability, while the second decade witnessed increased political efforts to have GM crops labeled in Canada as well as significant challenges from the low level comingling of GM crops with non-GM commodities. This article reviews the 20 y of GM crop production in Canada from a social science perspective that includes intellectual property, consumer acceptance and low level presence. PMID:25437238

Relationship between particle matter and meteorological data in Canada
Bahrami, Azad; Memarian Fard, Mahsa; Bahrami, Ala
2017-04-01
The fine particulate matter (PM2.5) has a strong influence on the hydrological cycle, cloud formation, visibility, global climate, and human health. The meteorological conditions have important effects on PM2.5 mass concentration. Canada's National Air Pollution Surveillance (NAPS) network measures air pollutants at urban, suburban and rural locations in Canada. In this study, the point monthly relationships between meteorological data provided by Environment of Canada and PM2.5 mass concentration from January 1st, 2010 to December 31st, 2015 of fifteen speciation stations in Canada were analyzed. The correlation analysis results between PM2.5 concentrations and precipitation as well as surface pressure demonstrated a negative correlation. It should be noted that the correlation between temperature and special humidity with PM2.5 in cold seasons and warm seasons were negative and positive respectively. Moreover, the weak correlation between wind speed and PM2.5 were obtained.

Sex With Neighbors: Canada and Canadians in the U.S. Homophile Press.
Stein, Marc
2017-01-01
This article examines U.S. homophile magazine contributions from and representations of Canada from 1953 to 1964. Drawing on 240 articles, letters, and other items that were published in ONE, Mattachine Review, and The Ladder, the essay first reviews Canadian-authored materials and then shows that U.S. gay and lesbian movement periodicals depicted Canada as more sexually conservative than the United States in three ways and more sexually liberal in one way. The magazines presented Canada as more sexually conservative in its failure to develop an organized gay and lesbian movement, its policies and practices of sexual censorship, and its opposition to progressive homosexual law reform. They portrayed Canada as more sexually liberal in the ways that its mainstream media covered homosexuality. The essay argues that U.S. homophile representations of Canada participated in the ongoing construction and reconstruction of U.S. nationalism. In demonstrating that the magazines generally represented Canada as more sexually conservative than the United States in the years from 1953 to 1964, the essay also shows that more recent depictions of Canada as more sexually liberal are relatively new.

Closed windows, open doors: geopolitics and post-1949 Mainland Chinese immigration to Canada.
Liu X-f; Norcliffe, G
1996-01-01
"Since 1949 there have been dramatic changes in the flow of migrants from Mainland China to Canada, which existing structural models of migration, emphasizing factors in the destination country, do not fully capture. Conditions in the country of origin, and geopolitical relationships between China and Canada, played a decisive role in this migration.... Changing geopolitical circumstances led China to develop an open-door policy between 1973 and 1989, leading to increasing flows of migrants to Canada. The political response in Canada to the Tiananmen Square massacre of 1989 was to allow all Chinese students and workers in Canada to stay, if they so wished.... The result was a large inflow making MCIS the third-largest group of immigrants to Canada in the early 1990s." (EXCERPT)

The present study focused on carbon to nitrogen ratio (C/N) and organic loading rate (OLR) optimization of goose manure (GM) and wheat straw (WS). Dealing the anaerobic digestion of poultry manure on industrial scale; the question of optimum C/N (mixing ratio) and OLR (daily feeding concentration) have significant importance still lack in literature. Therefore, Batch and CSTR co-digestion experiments of the GM and WS were carried out at mesophilic condition. The alkali (NaOH) solubilization pretreatment for the WS had greatly enhanced its anaerobic digestibility. The highest methane production was evaluated between the C/N of 20-30 during Batch experimentation while for CSTRs; the second applied OLR of (3g.VS/L.d) was proved as the optimum with maximum methane production capability of 254.65ml/g.VS for reactor B at C/N of 25. The C/N and OLR regression optimization models were developed for their commercial scale usefulness. Copyright © 2017 Elsevier Ltd. All rights reserved.

1995-12-01
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

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.

Canada-United States air quality agreement: Making progress
International Nuclear Information System (INIS)
1992-01-01
The Canada-USA Air Quality Agreement was signed in March 1991. Canada's commitment under the agreement is to reduce emissions of SO 2 in the seven easternmost provinces to 2.3 million tonnes/y by 1994 and to cap these emissions at 3.2 million tonnes/y by 2000; in addition, Canada agrees to reduce nitrogen oxide emissions from stationary sources by 100,000 tonnes/y by 2000 and to implement more stringent nitrogen oxide emission standards for vehicles from 1994-96. The USA agrees to reduce SO 2 emissions by ca 10 million tons/y below 1980 levels by 2000, to achieve a permanent cap of 8.95 million tons/y for electric utilities by 2010, to ensure that industrial emissions do not exceed 5.6 million tons, and to reduce total nitrogen oxide emissions by ca 2 million tons/y below 1980 levels, primarily through new regulations for power plants and automobiles. In Canada, SO 2 emissions are now within 16% of target, with control efforts centered around metal smelters and power plants. In the USA, considerable progress has been made in promulgating regulations that will implement the acid rain control provisions of the agreement. Both countries are sharing information, are continuing a variety of scientific and technical activities, and cooperating in areas such as emission inventorying, atmospheric modelling, deposition monitoring, effects research and monitoring, human health studies, and control technologies. In the USA, market based incentives are being used in controlling acid emissions and are being assessed for their potential use in Canada. 13 figs., 3 tabs

Environmental radioactivity in Canada 1986
International Nuclear Information System (INIS)
1987-01-01
The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. During 1986 the program was strongly influenced by radioactive fallout on Canada resulting from the Chernobyl nuclear reactor accident on April 26, 1986 in the Soviet Ukraine. The Environmental Radiation Hazards Division (ERHD) increased its frequency of analyses of environmental samples immediately following the accident. Interim screening limits for foodstuffs were developed. A measurement program for radioactivity in domestic and imported foods was implemented. The ERHD measurement program was supplemented by additional measurements conducted by many other private and government laboratories. Radiation doses to Canadian from Chernobyl fallout were extremely low with no group in the population receiving more than 10 microsieverts

2015-01-01
Full Text Available This 2014 roundtable discussion, hosted by the Canadian Association of General Surgeons, brought together general surgeons and gastroenterologists with expertise in endoscopy from across Canada to discuss the state of endoscopy in Canada. The focus of the roundtable was the evaluation of the competence of general surgeons at endoscopy, reviewing quality assurance parameters for high-quality endoscopy, measuring and assessing surgical resident preparedness for endoscopy practice, evaluating credentialing programs for the endosuite and predicting the future of endoscopic services in Canada. The roundtable noted several important observations. There exist inadequacies in both resident training and the assessment of competency in endoscopy. From these observations, several collaborative recommendations were then stated. These included the need for a formal and standardized system of both accreditation and training endoscopists.

The Light Goose Conservation Order (LGCO) was initiated in 1999 to reduce mid-continent populations of light geese (lesser snow geese Chen caerulescens and Ross's geese C. rossi). However, concern about potential for LGCO activities (i.e. hunting activities) to negatively impact non-target waterfowl species during spring migration in the Rainwater Basin (RWB) of Nebraska prompted agency personnel to limit the number of hunt days each week and close multiple public wetlands to LGCO activities entirely. To evaluate the effects of the LGCO in the RWB, we quantified waterfowl density at wetlands open and closed to LGCO hunting and recorded all hunter encounters during springs 2011 and 2012. We encountered a total of 70 hunting parties on 22 study wetlands, with over 90% of these encounters occurring during early season when the majority of waterfowl used the RWB region. We detected greater overall densities of dabbling ducks Anas spp., as well as for mallards A. platyrhynchos and northern pintails A. acuta on wetlands closed to the LGCO. We detected no effects of hunt day in the analyses of dabbling duck densities. We detected no differences in mean weekly dabbling duck densities among wetlands open to hunting, regardless of weekly or cumulative hunting encounter frequency throughout early season. Additionally, hunting category was not a predictor for the presence of greater white-fronted geese Anser albifronsin a logistic regression model. Given that dabbling duck densities were greater on wetlands closed to hunting, providing wetlands free from hunting disturbance as refugia during the LGCO remains an important management strategy at migration stopover sites. However, given that we did not detect an effect of hunt day or hunting frequency on dabbling duck density, our results suggest increased hunting frequency at sites already open to hunting would likely have minimal impacts on the distribution of non-target waterfowl species using the region for spring

Evolving Perspectives on Lyme Borreliosis in Canada
Sperling, JLH; Middelveen, MJ; Klein, D; Sperling, FAH
2012-01-01
With cases now documented in every province, Lyme borreliosis (LB) is emerging as a serious public health risk in Canada. Controversy over the contribution of LB to the burden of chronic disease is maintained by difficulty in capturing accurate Canadian statistics, especially early clinical cases of LB. The use of dogs as sentinel species demon-strates that potential contact with Borrelia burgdorferi spirochetes, as detected by C6 peptide, extends across the country. Dissemination of infected ticks by migratory birds and rapid establishment of significant levels of infection have been well described. Canadian public health response has focused on identification of established populations of the tick vectors, Ixodes scapularis and I. pacificus, on the assumption that these are the only important vectors of the disease across Canada. Strains of B. burgdorferi circulating in Canada and the full range of their reservoir species and coinfections remain to be explored. Ongoing surveys and historical records demonstrate that Borrelia-positive Ixodes species are regu-larly present in regions of Canada that have previously been considered to be outside of the ranges of these species in re-cent modeling efforts. We present data demonstrating that human cases of LB are found across the nation. Consequently, physician education and better early diagnoses are needed to prevent long term sequelae. An international perspective will be paramount for developing improved Canadian guidelines that recognize the complexity and diversity of Lyme borreliosis. PMID:23091570

Climate change effects on regions of Canada
International Nuclear Information System (INIS)
Bruce, J.P.
2002-01-01
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

Fueling the dragon : China's quest for energy security and Canada's opportunities
International Nuclear Information System (INIS)
Jiang, W.
2005-04-01
Potential opportunities for Canada were discussed in relation to China's growing economy. China's current dependency on foreign oil is approximately 40 per cent, and is expected to be over 60 per cent in less than 2 decades. With less than 4 per cent of global Gross Domestic Product (GDP), China consumes 31 per cent of the world's coal, 30 per cent of its iron, 27 per cent of steel and 40 per cent of cement. China is also currently building one of the most extensive highway infrastructures on earth so it can replace its 1 billion bicycles with cars. As a developing country, China is not subject to the emission reduction standards of the Kyoto Protocol. China has signed billions of dollars in agreements to buy energy and build pipelines, as well as opened doors for multinational corporations to enter China's domestic energy market. Canada is now competing for the pending award of contracts to build 4 nuclear reactors in China. Chinese interest in Canada is largely due to its huge oil reserves, particularly now that Alberta's oil sands have been classified as economically recoverable. A background of Chinese and Canadian relations was presented. In 2003, The Common Paper of the Canada-China Strategic Working Group was developed, in which both countries agreed to strengthen their bilateral dialogue on energy, research and development and sustainable development. Official endorsements have been followed by real business movement, with Chinese interest in buying stakes in the oil sands industry. However, unlike other resource rich countries, Canada has yet to strike a major deal with China, and any major energy cooperation between China and Canada will be closely watched by the United States. Canada is the largest source of imported oil for the United States. It was concluded that the broader strategic implications of Canada's relationship with China must be carefully considered. 5 figs

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)

Boom times : Canada's crude petroleum industry : analysis in brief
International Nuclear Information System (INIS)
Rowat, M.R.
2006-01-01
This document examined the trends in crude oil prices, the production and exports of Canada's crude petroleum industry, and Canada's imports of crude petroleum. As an exporter and importer of crude oil, Canada's petroleum industry is currently experiencing economic prosperity as a result of high oil prices combined with high global demand for oil. This document reviewed industry activity for 2005 and addressed the reasons for the first decline in Canadian crude oil production in 6 years. A quick review of soaring crude oil prices, supply and shortages was also presented. A review of exports revealed that since 1995, the United States has received 99 per cent of Canadian exports. Although production activity is occurring in 7 provinces, the biggest participant is Alberta, followed by Saskatchewan. In 2005, Canada produced 136.4 million cubic metres of crude petroleum, of which two-thirds came from Alberta. Saskatchewan contributed 18 per cent of total Canadian crude oil production, while offshore oil rigs in Newfoundland and Labrador contributed 13 per cent. The vast oil sands resource accounted for 42 per cent of the province's total production. Alberta oil export is piped entirely into the United States. In 2005, even with a slight drop in exports, Canadian oil exporters received $30 billion for their products, up from $25 billion the year before. Canada also supplied nearly 10 per cent of the American crude oil needs. According to the National Energy Board, Canadian refineries are approaching capacity. Canada's 19 refineries, which have a capacity of 320,000 cubic metres per day, operated at 92 per cent of capacity in 2005 to meet the needs of the domestic market. More imported petroleum was refined than Canadian sourced petroleum. In 2005, the gas and oil industry saw historically high profits, taxes paid and investments. 6 refs., 5 figs

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

An overview of radioactive waste management in Canada
International Nuclear Information System (INIS)
Liblong, S.W.; Wong, C.F.
2014-01-01
As a Tier I nuclear nation, with a comprehensive nuclear sector whose beginnings date back to the 1940's, Canada is faced with radioactive waste management challenges for a diverse range of radioactive material - from very low-level to high-level. The nuclear fuel cycle is fully realized in Canada, from uranium mines and mills through to significant reliance on nuclear energy thorough to a broad-based science & technology platform. Natural Resources Canada is responsible for Canadian nuclear policy, while the provincial governments decide on the management of their resources and energy mix within their jurisdictions. While the fundamental policy regarding responsibility for radioactive waste places the onus on the generator, the means by which this is accomplished is not prescriptive beyond meeting regulatory requirements. As a result, approaches to dealing with radioactive waste have evolved according to the needs and abilities of the various generators. This paper will provide an overview of radioactive waste management in Canada, highlighting the approaches used within various sectors for the different classifications of waste, and will also look at plans for future waste management capabilities being developed at this time (including issues related to disposal vs. management). Challenges to the development of an effective and comprehensive 'Canadian solution' will also be discussed. (author)

Energy Technology Data Exchange (ETDEWEB)
1976-12-01
Governments in Canada have made a number of changes in oil and gas policies and fiscal treatments recently. There remains a considerable question, however, whether Canada will have sufficient volumes of these two energy fuels available securely and economically in the years ahead. This report examines the position that oil and gas will occupy in Canada's energy future, and assesses the contribution that domestic supplies could provide. It was concluded that, under current and proposed royalty, taxation, and regulatory systems, the flow of investments into exploration and development will be insufficient to increase the domestic supply base to provide an acceptable level of future self-reliance. Additionally, because of jurisdictional factors, reinvestments from current production are not being directed to the areas of greatest resource potential in Canada. In order to illustrate the types and degrees of further policy and fiscal changes that are required, an investment program that could lead to a minimum acceptable level of production from Canadian sources was formulated. Recommendations for changes in fiscal regimes lead to a ''formula'' that directs 35 percent of net production revenue from current production to the exploration and development of new supplies; mobilizes new investment; and directs a greater portion of both these sources of funds to the development of potential supplies from remote and technologically difficult, high-risk areas. The implementation of this formula will require concessions by both the producing provinces and the Federal government together with commitments from producers.

Nuclear fuel waste policy in Canada
International Nuclear Information System (INIS)
Brown, P.A.; Letourneau, C.
1999-01-01
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.

Vegetation response to climate change : implications for Canada's conservation lands
Energy Technology Data Exchange (ETDEWEB)
Scott, D. [Environment Canada, Ottawa, ON (Canada). Adaptation and Impact Research Group; Lemieux, C. [Waterloo Univ., ON (Canada). Dept. of Geography
2003-05-01
Studies have shown that Canada's national parks are vulnerable to the impacts of climate change. A wide range of biophysical climate change impacts could affect the integrity of conservation lands in each region of Canada. This report examines the potential impact of climate change on landscape alterations and vegetation distribution in Canada's wide network of conservation lands. It also presents several ways to integrate climate change into existing conservation policy and adaptation strategies. Canada's conservation lands include provincial parks, migratory bird sanctuaries, national wildlife areas and wildlife protected areas. This is the first study to examine biome changes by applying an equilibrium Global Vegetation Model (GVM) to Canada's network of national park systems. Some of the policy and planning challenges posed by changes in landscape level vegetation were also addressed. The report indicates that in terms of potential changes to the biome classification of Canada's national forests, more northern biomes are projected to decrease. These northern biomes include the tundra, taiga and boreal conifer forests. 56 refs., 8 tabs., 6 figs.

Disciplinary and Legal Actions Against Dermatologists in Canada.
Nasseri, Eiman
2016-01-01
Dermatologists face a litany of professional and legal risks in practice. To review cases of disciplinary and legal action against dermatologists in Canada. The Canadian Medical Protective Association, all 10 provincial medical colleges, and the Canadian Legal Information Institute were contacted to obtain data on legal or disciplinary action taken against dermatologists in their records. A literature review was performed regarding litigation against dermatologists in other countries. Six dermatologists in Canada faced disciplinary action in the last 5 to 30 years. Seven dermatologists and 5 other specialists in Canada faced lawsuits relating to dermatology in the last 1 to 144 years. Procedures and therapy are the most frequently sources of lawsuits against dermatologists both at home and abroad. Dermatologists need to remain vigilant to avoid disciplinary action and lawsuits from their increasing and varied interactions with patients. © The Author(s) 2015.

A discourse on dental hygiene education in Canada.
Kanji, Z; Sunell, S; Boschma, G; Imai, P; Craig, B J
2011-11-01
Over the past decade, the discourse on dental hygiene education has gained momentum in Canada. This review provides insights into the evolution of dental hygiene education in Canada, briefly exploring the history and professional influences for diploma and baccalaureate education within the profession. The profession in Canada has yet to implement a national standardized entry-to-practice educational model, but the recent development of national educational competencies may prove to be a promising beginning. The review also discusses efforts to advance dental hygiene education in recent years, while exploring the political and professional pressures and challenges that remain. Further discourse on education and outcomes-related research can be effective in positively influencing governmental, professional and public opinions of higher entry-level education for dental hygiene which may ultimately result in regulatory change and improved client outcomes. © 2010 John Wiley & Sons A/S.

Nuclear criticality safety in Canada
International Nuclear Information System (INIS)
Shultz, K.R.
1980-04-01
The approach taken to nuclear criticality safety in Canada has been influenced by the historical development of participants. The roles played by governmental agencies and private industry since the Atomic Energy Control Act was passed into Canadian Law in 1946 are outlined to set the scene for the current situation and directions that may be taken in the future. Nuclear criticality safety puts emphasis on the control of materials called special fissionable material in Canada. A brief account is given of the historical development and philosophy underlying the existing regulations governing special fissionable material. Subsequent events have led to a change in emphasis in the regulatory process that has not yet been fully integrated into Canadian legislation and regulations. Current efforts towards further development of regulations governing the practice of nuclear criticality safety are described. (auth)

The history of providing public information on nuclear energy in Canada for more than 40 years is described. 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

Healthcare in Canada's North: Are We Getting Value for Money?
Young, T Kue; Chatwood, Susan; Marchildon, Gregory P
2016-08-01
To determine if Canadians are getting value for money in providing health services to our northern residents. Secondary analyses of data from Statistics Canada, the Canadian Institute of Health Information and territorial government agencies on health status, health expenditures and health system performance indicators. Per capita health expenditures in Canada's northern territories are double that of Canada as a whole and are among the highest in the world. The North lags behind the rest of the country in preventable mortality, hospitalization for ambulatory care sensitive conditions and other performance indicators. The higher health expenditure in the North is to be expected from its unique geography and demography. If the North is not performing as well as Canada, it is not due to lack of money, and policy makers should be concerned about whether healthcare can be as good as it could be.

Current research in Canada on biological effects of ionizing radiation
International Nuclear Information System (INIS)
Marko, A.M.
1980-05-01
A survey of current research in Canada on the biological effects of ionizing radiation has been compiled. The list of projects has been classified according to structure (organizational state of the test system) as well as according to the type of effects. Using several assumptions, ballpark estimates of expenditures on these activities have been made. Agencies funding these research activities have been tabulated and the break-down of research in government laboratories and in academic institutions has been designated. Wherever possible, comparisons have been made outlining differences or similarities that exist between the United States and Canada concerning biological radiation research. It has been concluded that relevant research in this area in Canada is inadequate. Wherever possible, strengths and weaknesses in radiation biology programs have been indicated. The most promising course for Canada to follow is to support adequately fundamental studies of the biological effects of radiation. (auth)

The Popularization of Astronomy in Canada
Trudel, J.-L.
1996-12-01
In Canada, astronomy has a longer history than most other sciences. The European settlers had to master the rudiments of astronomical practice, while the natural setting promoted geophysical observations of all kinds. In the nineteenth century, astronomy was part of natural theology and a resource for timekeepers and cartographers, but was increasingly pursued for its own sake by laymen. The creation of the Royal Astronomical Society of Canada marks a turning point. Though it appeared to unite professionals and amateurs, it became early on a conduit for the knowledge of the former to flow to the latter, supplementing the purely academic stream. It followed upon the success of new publications meant to acquaint readers with the facts of astronomy, for the hitherto unsuspected pleasures they might bring. In fact, some Canadian works of this kind reached a wide audience, in Canada and abroad, and the post-WWII period saw an almost complete disjunction between the formerly utilitarian aspects of popularization a nd the catering to interested laypeople, distinct from the professionals. By 1976, the transformation was complete. The science mastered by explorers and appealed to by believers had become both a field for professional investigations and a widely popularized corpus of star lore

Canada`s greenhouse gas emissions inventory
Energy Technology Data Exchange (ETDEWEB)
Jaques, A. [Environment Canada, Ottawa, ON (Canada)
1998-09-01
In 1994, Canada was the seventh largest global emitter of CO{sub 2}. The Kyoto Protocol has made it necessary to continue to improve methods for developing emissions inventories. An emissions inventory was defined as `a comprehensive account of air pollutant emissions and associated data from sources within the inventory area over a specified time frame that can be used to determine the effect of emissions on the environment`. The general approach is to compile large-scale emission estimates under averaged conditions for collective sources and sectors, using data that is available on a sectoral, provincial and national basis. Ideally, continuous emission monitors should be used to develop emissions inventories. Other needed improvements include additional research on emissions data, and increased support for international negotiations on reporting policies and related methodologies, verification procedures and adjustments. 1 ref., 5 figs.

Fertility Adaptation of Child Migrants to Canada
Adsera, Alicia; Ferrer, Ana
2013-01-01
This study analyzes the fertility behavior of immigrant women arriving to Canada before age 19 using the 20 per cent sample of the Canadian Census from 1991 through 2006. Findings show that fertility increases with age at immigration, and is particularly high for those immigrating in their late teens. This pattern prevails regardless of the country of origin or whether the mother tongue of the migrant is an official language in Canada or not. We do not find a ‘critical age’ at which the behavior of migrants with and without official mother tongue start to diverge by more, even though the fertility of migrants without official mother tongue is always higher on average. Formal education matters as the fertility of immigrants who arrived to Canada before adulthood and graduated from college is similar to that of their native peers regardless of their age of arrival. However, the fertility of those with less than tertiary education increasingly diverges with age at migration from similarly educated Canadians. PMID:23800074

Avoidable cost of alcohol abuse in Canada.
Rehm, Jürgen; Patra, Jayadeep; Gnam, William H; Sarnocinska-Hart, Anna; Popova, Svetlana
2011-01-01
To estimate avoidable burden and avoidable costs of alcohol abuse in Canada for the year 2002. A policy effectiveness approach was used. The impact of six effective and cost-effective alcohol policy interventions aimed to reduce alcohol consumption was modeled. In addition, the effect of privatized alcohol sales that would increase alcohol consumption and alcohol-attributable costs was also modeled. The effects of these interventions were compared with the baseline (aggregate) costs obtained from the second Canadian Study of Social Costs Attributable to Substance Abuse. It was estimated that by implementing six cost-effective policies from about 900 million to two billion Canadian dollars per year could be saved in Canada. The greatest savings due to the implementation of these interventions would be achieved in the lowering of productivity losses, followed by health care, and criminality. Substantial increases in burden and cost would occur if Canadian provinces were to privatize alcohol sales. The implementation of proven effective population-based interventions would reduce alcohol-attributable burden and its costs in Canada to a considerable degree. Copyright © 2010 S. Karger AG, Basel.

Government of Canada Action Plan 2000 on Climate Change
International Nuclear Information System (INIS)
2000-01-01
In this first National Climate Change Business Plan the Government of Canada affirms its intention to invest up to $500 million over five years on specific actions to reduce greenhouse gas emissions. This sum is in addition to the action plans being put forward by the provincial and territorial governments and in addition to the $625 million investment over five years announced in Budget 2000. Action Plan 2000 targets key sectors, and the measures announced are expected to take Canada one third of the way to achieving the target established in the Kyoto Protocol by reducing Canada's GHG emissions by 65 megatonnes per year during the 2008-2012 commitment period. The key sectors targeted include the areas of transportation, oil, gas and electricity production, industry, buildings, forestry and agriculture, i. e. sectors that together account for over 90 per cent of Canada's GHG emissions.The Action Plan focuses on reducing GHG emissions in a cost effective way; draws extensively on the best ideas put forward by the provinces, territories and other stakeholders; encourages action by industry and consumers; complements measures and actions by the provinces and territories to address regional issues; and sets the stage for long-term behavioural, technological and economic changes. The remainder of Canada's Kyoto commitments will be addressed by actions in future plans which are currently in the process of being developed, together with the development of further details of this first National Climate Change Business Plan

Presentation to the Canada-US power system outage public forum
International Nuclear Information System (INIS)
McMonagle, R.
2003-01-01
Solar manufacturers, distributors, retailers, installers, and consultants across Canada are represented by the Canadian Solar Industries Association (CanSIA). The author clarified the solar situation in Canada, noting that Canada has a similar or better solar resource than nations who are currently solar leaders, and that few solar markets in the world today are cost-competitive without the support of government. The reliability of the electrical grid can be increased with the help of solar energy, and it can also increase the diversification of energy sources. Even during winter ice storms, solar buildings can function without an outside source of heat. Similarly, no outside source of electricity is required for such a building to function during summer blackouts. Growth of the global market for solar power exceeds 25 per cent annually. Approximately 1 per cent of Canada's electricity supply could be provided by solar through proper planning, and over 2 per cent by 2025 in Ontario. The author argued that several measures must be implemented in Canada for the country to reach its potential in support of the electrical grid. The measures include a National Renewable Energy Plan, a Renewable Portfolio Standard, net metering, feed in policy, elimination of electric rate subsidies and the introduction of time-of-day metering, and subsidies. 3 tabs

Lee, Peter G.; Hanneman, Matt; Cheng, Ryan [Global Forest Watch Canada (Canada)
2011-08-15
For over 200 years, energy production and consumption, along with all human activities, have been contributing to global warming. This report is part of a project that examines 10 major energy sectors to provide information on Canada's energy options in the face of climate change; this present study gives information on hydropower reservoirs and associated dams in Canada. The mapping, jurisdictional and ecological distribution of reservoirs and dams across Canada is provided herein. Canada's hydropower installations are composed of 271 large hydropower facilities covering 58,015 km2 with a capacity of 71,857 MW, accounting for 44% of Canada's total technical hydroelectric capacity. Quebec, Ontario and British Columbia are the provinces with the most large hydropower dams; 19% of the watersheds are occupied in part by hydropower reservoirs and the taiga shield, boreal shield and montane cordillera ecozones contain most of the reservoir areas. The majority of future developments are expected to be built within 5km of intact forest landscapes.

The new global energy geopolitical game : is Canada ready to play?
Energy Technology Data Exchange (ETDEWEB)
Hester, A.
2009-01-15
This paper discussed Canada's foreign energy policy by reviewing Canada's relationship with the United States in the context of energy geopolitics. The United States will soon be required to relinquish its dominant position as a defender of the free passage through the Strait of Hornuz and refocus its energies on developing resources in the western hemisphere. Canada's role will continue to develop as a result of the country's abundant energy resources. Leadership and new policies are needed to achieve Canada's energy potential in the future. Policies are needed to ensure the sustainable development of hydrocarbon resources, as well as to ensure the development of technologies for using, storing, and disposing of carbon. The paper argued that government partnerships with industry are needed to ensure advancements in technology development. A national plan is needed to establish strong international partnerships. It was concluded that the creation of a constructive energy architecture will provide the basis for Canada's leadership in the future energy sector. 79 refs.

The potential for western Canada to become a leader in electrically powered land transport
Energy Technology Data Exchange (ETDEWEB)
Perl, A.; Gilbert, R. [Simon Fraser Univ., Burnaby, BC (Canada)
2010-07-01
Canada's western provinces are among the most oil-intensive jurisdictions in the world. Per capita consumption in 2007 was 70 percent higher than that of eastern Canada. While western Canada will be buffered as a producer of oil, predicted swings in oil prices may disrupt the fiscal capacity of producer provinces. The price of crude oil in western Canada is the same price established in world markets. This paper examined some of the opportunities available for western Canada to move away from oil consumption by becoming a leader in electric traction. Methods of replacing oil-based transportation with the use of electric vehicles were discussed. Western Canada's capacity to produce electricity from renewable resources was evaluated. Economic opportunities related to the electrification of land transport were also examined. The report concluded by stating that a clear vision and policy framework for supporting new technologies for surface transport across western Canada are needed. 72 refs., 4 figs.

Goose parvovirus (GPV) is a highly contagious and deadly disease for goslings and Muscovy ducklings. To compare the differences in immune response of geese immunized with GPV-VP1 DNA-based and live attenuated vaccines. Shitou geese were immunized once with either 20 μg pcDNA-GPV-VP1 DNA gene vaccine by gene gun bombardment via intramuscular injection, or 300 μg by i.m. injection, or 300 μL live attenuated vaccine by i.m. injection, whereas 300 μg pcDNA3.1 (+) i.m. or 300 μL saline i.m. were used as positive and negative controls, respectively. Each group comprised 28 animals. Peripheral blood samples were collected from 2-210 days after immunization and the proliferation of T lymphocytes, the number of CD4(+) and CD8(+) T cells and the level of IgG assessed. Statistical analysis was performed using a one-way analysis of variance with group multiple comparisons via Tukey's test. The pcDNA-GPV-VP1 DNA and attenuated vaccine induced cellular and humoral responses, and there were no differences between the 20 and 300 μg group in the responses of proliferation of T lymphocyte and the CD8(+) T-cell. However, as to CD4(+) T-cell response and humoral immunity, the 20 μg group performed better than the 300 μg group, which induced better cellular and humoral immunity than live attenuated vaccine. This study showed that it is possible to induce both cellular and humoral response using DNA-based vaccines and that the pcDNA-GPV-VP1 DNA gene vaccine induced better cellular and humoral immunity than live attenuated vaccine.

Full Text Available ABSTRACT The mainland population of the ruddy-headed goose (Chloephaga rubidiceps breeds in southern Patagonia and winters in the south of Buenos Aires province (Argentina, with a recent estimated size at around 900 individuals. This population is considered "in danger of extinction", while the Malvinas (Falkland Islands population is in well conservation status, with an estimated size of 40,000 birds. The aim of this work is to contribute with updated information about the ruddy-headed goose's population wintering in southern Buenos Aires province. The specific objectives were to better delimit its wintering area, to look for sites with large numbers, to study its habitat used, and to identify main threats to the species. Two intensive surveys were conducted during the austral winter of 1999. The results: (1 confirm the low abundance of the ruddy-headed goose supporting its critical conservation status, (2 corroborate its very restricted distribution, with more than 80 % of sightings concentrated in an area of 13,000 ha in southern Buenos Aires province, and (3 suggest that changes in the species' habitat use during the wintering season appear to be a response to changes in habitat availability, resulting from the growth of crops and pastures. The overlap between the species wintering distribution and the main wheat cropping areas of Argentina results in serious threats to this goose. Management actions are discussed to contribute to the conservation of this endangered species.La población continental del Cauquén colorado (Chloephaga rubidiceps cría en el sur de la Patagonia e inverna en el sur de la provincia de Buenos Aires (Argentina, con un tamaño poblacional estimado recientemente en alrededor de 900 individuos.

Pricing electricity for sustainability : climate change and Canada's electricity sector
International Nuclear Information System (INIS)
2010-01-01
The electricity sector is Canada's largest single source of greenhouse gas (GHG) emissions. This paper discussed electricity and carbon pricing approaches to reducing GHG emissions in the electricity sector. An overview of the links between electricity pricing and climate change was presented, and current and emerging trends in electricity pricing related to encouraging energy conservation were reviewed. Market prices and failures were discussed. Approaches to pricing electricity included an increase in block prices; time-of-use prices; demand-side management and energy efficiency; and carbon pricing in Canada and electricity pricing signals. The study showed that several provincial utilities in Canada are experimenting with market-based pricing approaches for electricity and carbon that may help to reduce GHG emissions over time. Concerns over electricity supply and the negative environmental impacts of electricity production may lead to the full social pricing of electricity in some regions of Canada. 46 refs., 3 tabs., 5 figs.

This study attempts to provide basic information on overseas employment to the radiological technologists and students majoring in radiology in Korea who consider the overseas employment by investigating the job consciousness for radiological technologists in Canada and Australia which have a high level of interest for overseas employment and want to compare their status with that of Korean radiological technologists. This study was performed by visiting hospitals such as Prince George Regional Hospital, 1475 Edmonton Street, Prince George, BC, Canada on August 13, 2007, Alfred Hospital, Commercial Road Melbourne 3004, Australia on August 4, 2008, and other Korea hospitals that show the similar scale as Canada and Australia on September 10, 2007. The results were summarized as follows : 1. Differences were observed in this sexual composition, such as 18 males (90%) in Korea, 14 females (73.7%) in Canada, and 25 females in Australia (86.2%). 2. The item of 'aptitude' which is one of the most important criteria, showed the highest level in Korea, Canada, and Australia, and the second most considered item was 'salary'. 3. In the values in jobs, the items of 'economic self-sufficiency', 'recognized by others', and 'establishing a social position' represented high levels in Korea, and the items of 'like the job itself', 'establishing self-actualization', 'feel the meaning of life', and 'make new friends' showed high levels in Canada and Australia. 4. Regarding the item of 'a job is important as much as a marriage', 'Yes' showed high level in Korea, and 'No' showed high levels in Canada and Australia. 5. Radiological technologists in Korea demonstrated a low level in the job consciousness compared to those of Canada and Australia. Although this study shows some limitations for showing whole idea of radiological technologists due to the lack of the scope in samples for each country as a practical manner, this study can be regarded significant to compare some countries

Target Canada: Lesson from Failure of International Entry
Directory of Open Access Journals (Sweden)
Nikolay Megits
2015-10-01
Full Text Available Target Corporation, the second largest retailing company in the United States, is well known for their value to guests (customers, continuous innovation, and exceptional guest experience. With a desire of international expansion, Target announced their Foreign Direct Investment (FDI plans for Target Canada in January 2011. In August 2012, headquarters opened in Mississauga with 124 store openings following throughout 2013. Two years later an unsuccessful attempt at entering the Canadian retail market resulted in a loss of over $5.4B. Target Canada rushed into its expansion into the Canadian foreign market and corporation was unable to repeat the successful US concept in Canada for several factors. Target’s scale was too large, the timeline was too aggressive, and the entrance method was attractive from a price perspective. As a consequence, Target was unable to efficiently manage the whole supply-chain, resulting in an unpleasant shopping experience for the customers. Finally, the incapability to differentiate itself from other retailers led to an unsuccessful attempt at gaining greater market share from the competition. Despite the fact that Target does not have a plan to enter back into Canada, this case offers suggestions for Target’s location strategy and plausible alternatives when revisiting potential re-entry into the international retail market. Recommendations are given based on what they learned from their first attempt at failed expansion.

1997 report on occupational radiation exposures in Canada
International Nuclear Information System (INIS)
1997-01-01
This series of reports provides statistics on occupational radiation exposures of monitored workers in Canada. The information is based on the data in the National Dose Registry (NDR) maintained by the Radiation Protection Bureau of Health Canada. The Registry is a centralized record-keeping system containing dose information on all monitored workers in Canada. It includes records from the National Dosimetry Services, as well as data submitted by nuclear power generating stations, Atomic Energy of Canada Ltd., uranium mines and private dosimeter processing companies. Information for input into the NDR is received in a number of different physical forms. Data from the National Dosimetry Service are fed directly from the dosimeter reading stations into a computer. Most other dose records are submitted to the Registry in computer readable form. The report provides data on the two consecutive years prior to the year in which the data are extracted form the database. The data for the second year will be close to stable at the time of data extraction. Some changes may still occur, for which the most frequent causes are: 1. a high dose to a dosimeter is judged to be non-personal after investigation; 2. a job category of a worker is updated; or 3. dosimeters or data are returned late. The report therefore contains preliminary data on the second year, and more complete data on the first year

Global warming and the forest fire business in Canada
International Nuclear Information System (INIS)
Stocks, B.J.
1991-01-01
The current forest fire situation in Canada is outlined, and an attempt is made to predict the impact of global warming on the forest fire business in Canada. Despite the development of extremely sophisticated provincial and territorial fire management systems, forest fires continue to exert a tremendous influence on the Canadian forest resource. Research into the relationship between climate warming and forest fires has fallen into two categories: the effect of future global warming on fire weather severity, and the current contribution of forest fires to global atmospheric greenhouse gas budgets. A 46% increase in seasonal fire severity across Canada is suggested under a doubled atmospheric carbon dioxide concentration scenario. Approximately 89% of carbon released to the atmosphere by forest fire burning is in the form of carbon dioxide, 9% is carbon monoxide, and the remaining carbon is released as methane or non-methane hydrocarbons. It is estimated that forest fires in northern circumpolar countries contribute from 1-2% of the carbon released globally through biomass burning. Fire may be the agent by which a northerly shift of forest vegetation in Canada occurs. 13 refs., 2 figs
