    Fraser syndrome is a rare autosomal recessive disorder characterized by cryptophthalmos, cutaneous syndactyly, laryngeal, and urogenital malformations. We present a population-based epidemiological study using data provided by the European Surveillance of Congenital Anomalies (EUROCAT) network...... of birth defect registries. Between January 1990 and December 2008, we identified 26 cases of Fraser syndrome in the monitored population of 12,886,464 births (minimal estimated prevalence of 0.20 per 100,000 or 1:495,633 births). Most cases (18/26; 69%) were registered in the western part of Europe, where...... was particularly high (42%). Most cases of Fraser syndrome (85%) are suspected prenatally, often due to the presence of the association of renal agenesis and cryptophthalmos. In the European population, a high proportion (82%) of pregnancies is terminated, thus reducing the live birth prevalence to a third...

    2013-01-01

    We were deeply saddened to learn that Gordon Fraser had passed away on 3 January. During his 25-year career at CERN, until his retirement in 2002, he made many valuable contributions to the Laboratory, in particular as editor of CERN Courier.   Gordon’s life in science began at Imperial College London, where he obtained a PhD with the theory group of the future Nobel laureate Abdus Salam. He then spent time at Tel Aviv University in Yuval Ne’eman’s group and at Brighton University, before changing career to become a journalist, at first for Computer Weekly in London. He moved into scientific editing at the Rutherford Appleton Laboratory in 1975 and it was from there that he was hired to join the publications team at CERN in 1977. By 1982 Gordon had become the editor of the CERN Courier. During his time at the helm, both particle physics and the Courier changed considerably. Under his careful stewardship aspects of publishing were outsourced, leading to a...

  7. The neural signature of the Fraser illusion: An explorative EEG study on Fraser-like displays

    Full Text Available We studied neural correlates accompanying the Fraser spiral illusion. The Fraser spiral illusion consists of twisted cords superimposed on a patchwork background arranged in concentric circles, which is typically perceived as a spiral. We tested four displays: the Fraser spiral illusion and three variants derived from it by orthogonally combining featural properties. In our stimuli, the shape of the cords comprised either concentric circles or a single spiral. The cords themselves consisted of black and white lines in parallel to the contour of the cords (i.e. parallel cords, or oblique line elements (i.e. twisted cords. The displays with twisted cords successfully induced illusory percepts, i.e. circles looked like spirals (the Fraser spiral illusion and spirals looked like circles (i.e., a ‘reverse Fraser illusion’. We compared the event-related potentials in a Stimulus (Circle, Spiral × Percept (Circle, Spiral design. A significant main effect of Stimulus was found at the posterior scalp in an early component (P220-280 and a significant main effect of Percept was found over the anterior scalp in a later component (P350-450. Although the EEG data suggest stimulus-based processing in posterior area in an early time window and Percept based processing in the later time window, an overall clear-cut stimulus-percept segregation was not found due to additional interaction effects. Instead, the data, especially in the later time window in the anterior area, point at differential processing for the condition comprising circle shapes but spiral percepts (i.e. the Fraser illusion.

    Microplastics are a source of anthropogenic contamination in watercourses and water bodies around the world. The extent of the implications associated with microplastics, however, is not fully known. These plastic particles, less than 5mm in diameter by definition, threaten a wide range of aquatic and land-based organisms, as the ingestion of microplastics by aquatic organisms can form blockages in digestive tracts, and can provide pathways for other contaminants to enter their bodies (Ziajahromi et al. 2017). Land-based organisms can then ingest the contaminated organisms, potentially impacting their health. Microplastics can be introduced into the aquatic environment through aquatic or land-based sources (Ziajahromi et al. 2017). A river system that is at a particular threat from microplastic contamination is the Fraser River. The Fraser River is a major salmon bearing river system in British Columbia and drains an area of over 220,000 km2. Potential sources of microplastic contamination include pulp and lumber mills near Prince George and Quesnel, the agriculturally dominated Fraser Valley, and the highly urbanized and industrialized stretch of the Lower Mainland east of Vancouver. Preliminary tests in the summer of 2016 on 200 liters of Fraser River water, processed through a 45 µm sieve, revealed the presence of microplastics, including the detection of blue dye polyethylene by Raman spectroscopy. Since then additional water samples were taken monthly at the Fraser River Observatory in Fort Langley from October 2016 to March 2017, and then bi-weekly commencing in April 2017. These samples are to be analysed at Woods Hole Oceanographic Institution (WHOI) in the Fall of 2017. This ongoing project aims at identifying the presence, amount, and type of microplastics being transported by the Fraser River to the coastal ocean. Ziajahromi, S.,et al., 2017.

    Full Text Available Tropical peat-swamp forests are one of  the largest near-surface reserves of terrestrial organic carbon,  but rnany peat-swamp forest tree species decreased due over-exploitation, forest fire and conversion of natural forests into agricultural lands. Among those species are slow-growing Calophyllum  hoseiand Ploiarium  alternifolium, two species are good for construction of boats, furniture, house building and considerable attention from pharmacological viewpoint for human healthly. This study was aimed at understanding the effects of arbuscular mycorrhizal (AM fungi on early growth of  C. hosei and P.alternifoliumunder greenhouse condition. Seedlings of C. hosei and P.alternifoliumwere inoculated with AM fungi: Glomus clarum and Glomus aggregatum ,or uninoculated under greenhouse condition during 6 months. AM colonization,   plant growth,  survival rate and  nutrient  content  (P, Zn  and B were measured. The percentage of C. hoseiand P.alternifolium ranged from 27-32% and 18-19%,  respectively. Both inoculated seedling species had greater plant  height, diameter, leaf number, shoot and root dry weight than control  seedlings.   Nutrient  content  of  inoculated  plants  were increased with AM colonization- Survival rates of  inoculated plants were higher (100%  than those of  control plants (67%. The results suggested that inoculation of AM fungi could improve the early growth of C. hoseiand P.alternifolium grown in tropical peat-swamp forest therefore  this finding has greater potential impact if this innovative technology applied in field scales which are socially acceptable, commercially profitable and environmentally friendly.

  14. 2000 emission inventory for the Lower Fraser Valley airshed

    International Nuclear Information System (INIS)

    2002-10-01

    This emissions inventory is a compilation of all emissions in the Lower Fraser Valley International Airshed. Its objective is to harmonize the inventory data of Canada's Greater Vancouver Regional District (GVRD), the Fraser Valley Regional District (FVRD) and Whatcom County in the United States. It provides an idea of the current state of air emissions on both sides of the Canada-United States border. This inventory provides information regarding the types of emissions sources in the region, their location and the amount of air pollution emitted within a given time frame. It is designed to help manage air quality by identifying sectors which need to be more vigilant. The common air pollutants addressed in the inventory include total particulate matter, nitrogen oxides, sulphur oxides, volatile organic compounds, carbon monoxide, and ammonia. The greenhouse gases include carbon dioxide, methane, and nitrous oxide. The inventory distinguishes between point, area, and mobile sources. Carbon monoxide emissions are found to be dominated by cars, trucks and non-road engines. Nitrogen oxide emissions are also dominated by cars, trucks, marine vessels and non-road engines. Natural sources such as trees and vegetation contribute to volatile organic compounds, as do cars, lights trucks and solvent evaporation from industrial, commercial and consumer products. Marine vessels are the largest contributors of sulphur oxide emissions in the region. In addition, the petroleum industry emits 26 per cent of sulphur oxide emissions in the region. Significant amounts of particulate matter come from area sources such as wind erosion in the agricultural sector. Point sources for PM include bulk shipping terminals and the wood products industry. Agriculture contributes the largest amount of ammonia in the region. refs., tabs., figs

    The climatic changes that are expected to occur in British Columbia's Lower Fraser Valley over the next century were described in this report which included information about the science of climate change and the development of global climate models that provide estimates of global climate for the coming century. The confidence that scientists have in these models was reflected in the fact that most can simulate the important seasonal and geographical large scale features of the global climate, and that many of the large scale changes that are effected by greenhouse gas concentrations can be explained in terms of physical processes which operate around the world. The models also reproduce with reasonable accuracy the variations of climate such as the El Nino phenomena., the cooling due to the Mount Pinatubo eruption in 1991 and the global warming that occurred over the past 100 years. Three climate stations were analyzed in this study to assess the climate change of the Valley. Climatic change is influenced by increased concentrations of greenhouse gases in the atmosphere which in turn cause accelerated global warming. Scientists generally believe that the combustion of fossil fuels and other human activities are a major reason for the increased concentration of carbon dioxide. Plant respiration and the decomposition of organic matter releases 10 times more CO 2 than that released anthropogenically, but these releases are in balance with plant photosynthesis. The rate of warming in the Lower Fraser Valley is uncertain, but climate models suggest it could be about 3 to 4 degrees warming with wetter winters and drier summers by the end of the century. The Valley currently has mild temperatures and high precipitation because of its proximity to the Pacific Oceans and the surrounding mountains. Global warming can have an impact on sea levels along the coast, spring flooding, summer drought, coastal ecosystems, air quality, occurrences of forest fires, and recreation

  18. Theology and psychology – the interdisciplinary work of Fraser Watts

    Directory of Open Access Journals (Sweden)

    Willem J. Smith

    2005-10-01

    Full Text Available In the preface to his book, Theology and Psychology, Fraser Watts, a lecturer in Theology and Natural Science at the University of Cambridge, states that he approaches “… the interface between theology and psychology by looking at each discipline from the perspective of the other. This includes a religious perspective on several current hot topics in psychology, such as evolution, neuroscience, and computer intelligence. I also consider theological topics like divine action, salvation history and eschatology, in each case using the psychological perspective in a different way”. By taking an interdisciplinary approach, Watts aims at proposing a psychology of religious experience. He considers theology to be the rational reflection on the Christian tradition. When exponents of this tradition are in dialogue with exponents of psychology, the focus falls on human nature. Watts admits that a certain lack of competence in one of the two disciplines can be a problem when working in an interdisciplinary way. However, he is willing to take the risk. Watts worked in psychology for 25 years and was also involved with a medical research council, before taking up a position at the Faculty of Divinity, University of Cambridge.

    Undergraduate students in the Geography and Biology Departments at the University of the Fraser Valley (UFV) have been provided the opportunity to participate in the time series sampling of the Fraser River at Fort Langley and Fraser Valley tributaries as part of the Global Rivers Observatory (GRO, www.globalrivers.org) which is coordinated by Woods Hole Oceanographic Institution and Woods Hole Research Center. Student research has focussed on Clayburn, Willband and Stoney Creeks that flow from Sumas Mountain northwards to the Fraser River. These watercourses are increasingly being impacted by anthropogenic activity including residential developments, industrial activity, and agricultural landuse. Students are instructed in field sampling protocols and the collection of water chemistry data and the care and maintenance of the field equipment. Students develop their own research projects and work in support of each other as teams in the field to collect the data and water samples. Students present their findings as research posters at local academic conferences and at UFV's Student Research Day. Through their involvement in our field research our students have become more aware of the state of our local streams, the methods used to monitor water chemistry and how water chemistry varies seasonally.

  20. Vulnerability of Fraser River sockeye salmon to climate change: a life cycle perspective using expert judgments.

    Science.gov (United States)

    McDaniels, Tim; Wilmot, Sarah; Healey, Michael; Hinch, Scott

    2010-12-01

    Fraser River sockeye salmon have been the basis for a major commercial fishery shared by Canada and the United States, and an important cultural foundation for many aboriginal groups; they are also of huge ecological significance throughout the Fraser Basin. The potential for altered aquatic habitat and temperature regimes due to climate change is an important concern for Fraser River sockeye salmon. This paper characterizes the vulnerability of Fraser River sockeye salmon to future climate change using an approach that is novel on three counts. First, previous efforts to assess the vulnerability of salmon to climate change have largely focused on only part of the life cycle, whereas we consider climate vulnerability at all stages in the life cycle. Second, we use the available scientific literature to provide a basis for structuring and eliciting judgments from fisheries science and management experts who research and manage these systems. Third, we consider prospects for mitigating the effects of climate change on sockeye salmon. Tests showed that participants' judgments differentiated in statistically significant ways among questions that varied in terms of life stages, spawning regions and climate scenarios. The consensus among participants was that Fraser River sockeye are most vulnerable to climate change during the egg and returning adult stages of the life cycle. A high temperature scenario was seen as imposing the greatest risk on sockeye stocks, particularly those that migrate to the upper reaches of the Fraser River system and spawn earlier in the summer. The inability to alter water temperature and the highly constrained nature of sockeye management, with competing gear types and sequential fisheries over a long distance, suggest the potential to mitigate adverse effects is limited. Fraser River sockeye already demonstrate a great deal of adaptive capacity in utilizing heterogeneous habitats in different river sub-basins. This adaptability points to the

    Fraser syndrome (FS) is a phenotypically variable, autosomal recessive disorder characterized by cryptophthalmus, cutaneous syndactyly and other malformations resulting from mutations in FRAS1, FREM2 and GRIP1. Transient embryonic epidermal blistering causes the characteristic defects of the disorder. Fras1, Frem1 and Frem2 form the extracellular Fraser complex, which is believed to stabilize the basement membrane (BM). However, several cases of FS could not be attributed to mutations in FRAS1, FREM2 or GRIP1, while Fraser syndrome displays high clinical variability, suggesting there is an additional genetic, possibly modifying contribution to this disorder. AMACO, encoded by the VWA2 gene, has a very similar tissue distribution to the Fraser complex proteins in both mouse and zebrafish. Here, we show that AMACO deposition is lost in Fras1 deficient zebrafish and mice and that Fras1 and AMACO interact directly via their CSPG and P2 domains. Knockdown of vwa2, which alone causes no phenotype, enhances the phenotype of hypomorphic Fras1 mutant zebrafish. Together, our data suggest that AMACO represents a novel member of the Fraser complex. PMID:24232570

    The Fraser Island slide complex is located on eastern Australia's continental slope. Two potentially tsunamigenic submarine landslides identified here as the 'North Fraser Island Upper Slope Slide' (25km2 in area, 100m thick) and the 'Middle Fraser Island Middle Slope Slide' (12km2 in area, 50m thick) are described. Morphologic, sedimentologic and geomechanical properties for these slides are compared to data reported for existing submarine landslides located to the south in New South Wales (NSW). The two Fraser Island slides are translational, box-shaped, slab slides. We suspect that the slabs remained intact during downslope transport. The upper slope slide is situated at a water depth of approximately 750m at the northern end of the Fraser Canyon complex. The head of this slide has apparently detached from a structural surface comprised of a Miocene reef complex located beneath the continental shelf edge. The middle slope slide is situated on a large plateau to the south of the Fraser Canyon complex in 1500m of water. Cores taken in the continental slope within both slides are long and present hemipelagic muds. Cores taken adjacent to both slides are short and terminate in stiff muds of suspected Miocene or Pliocene age. Additionally, the core adjacent to the upper slope slide presents a near surface layer of upper-fining of coarse to fine shelly sand which we interpret to be a turbidite deposit. This layer was deposited above hemipelagic muds which are ubiquitously present on the upper eastern Australian continental slope in NSW and Southern Queensland.

    The Fraser Island Slide complex is located on eastern Australia's continental slope offshore Fraser Island in southern Queensland. Morphologic, sedimentologic and geomechanical properties data for two submarine landslides, the 'North Fraser Island Upper Slope Slide' (upper slope slide) and the 'Fraser Island Middle Slope Slide' (middle slope slide) are described. Both of these features are box-shaped, slide scars from which rectangular slabs of material have been shed. The upper slope slide is situated at a water depth of approximately 750 m at the northern end of the Fraser Canyon. The head of this slide has apparently detached from a structural surface comprised of a Miocene reef complex located beneath the continental shelf edge; this slide is estimated to be 25 square kilometres in area and an average of 100m thick. The middle slope slide is situated in 1500 m of water at the southern end of the Fraser Canyon. It estimated to be 12 square kilometres in area and 50 m thick. Cores taken in the continental slope within both slides are long (upper slope 5.65 m, middle slope 3.64 m) and are dominantly comprised of hemipelagic mud. Cores taken adjacent to both slides are short (upper slope 1.33m, middle slope 0.43m) and terminate in stiff muds of suspected Miocene or Pliocene age. Additionally, the 1.33 m core on the slope adjacent to the upper slide presents a near surface layer of upper-fining of coarse to fine shelly sand which we interpret to be a turbidite deposit, this layer was deposited within hemipelagic muds which are ubiquitously present on the upper eastern Australian Continental Slope in New South Wales and Southern Queensland.

An extracellular matrix protein containing VWA-like domains related to those in matrilins and collagens (AMACO), encoded by the VWA2 gene, has a very similar tissue distribution to the Fraser complex proteins in both mouse and zebrafish. Here, we show that AMACO deposition is lost in Fras1-deficient zebrafish and mice and that Fras1 and AMACO interact directly via their chondroitin sulfate proteoglycan (CSPG) and P2 domains. Knockdown of vwa2, which alone causes no phenotype, enhances the phenotype of hypomorphic Fras1 mutant zebrafish. Together, our data suggest that AMACO represents a member of the Fraser complex.

    The geologic map of the Fraser quadrangle, Grand County, Colo., portrays the geology along the western boundary of the Front Range and the eastern part of the Fraser basin near the towns of Fraser and Winter Park. The oldest rocks in the quadrangle include gneiss, schist, and plutonic rocks of Paleoproterozoic age that are intruded by younger plutonic rocks of Mesoproterozoic age. These basement rocks are exposed along the southern, eastern, and northern margins of the quadrangle. Fluvial claystone, mudstone, and sandstone of the Upper Jurassic Morrison Formation, and fluvial sandstone and conglomeratic sandstone of the Lower Cretaceous Dakota Group, overlie Proterozoic rocks in a small area near the southwest corner of the quadrangle. Oligocene rhyolite tuff is preserved in deep paleovalleys cut into Proterozoic rocks near the southeast corner of the quadrangle. Generally, weakly consolidated siltstone and minor unconsolidated sediments of the upper Oligocene to upper Miocene Troublesome Formation are preserved in the post-Laramide Fraser basin. Massive bedding and abundant silt suggest that loess or loess-rich alluvium is a major component of the siltstone in the Troublesome Formation. A small unnamed fault about one kilometer northeast of the town of Winter Park has the youngest known displacement in the quadrangle, displacing beds of the Troublesome Formation. Surficial deposits of Pleistocene and Holocene age are widespread in the Fraser quadrangle, particularly in major valleys and on slopes underlain by the Troublesome Formation. Deposits include glacial outwash and alluvium of non-glacial origin; mass-movement deposits transported by creep, debris flow, landsliding, and rockfall; pediment deposits; tills deposited during the Pinedale and Bull Lake glaciations; and sparse diamictons that may be pre-Bull Lake till or debris-flow deposits. Some of the oldest surficial deposits may be as old as Pliocene.

    2012-05-01

    Full Text Available This paper seeks to portray, in a synthetic form, the theoretical elaboration of American political scientist Nancy Fraser about her threedimensional model analysis (recognition, redistribution and parity of participation as a form of theoretical and practical intervention in the debates of recognition and shape of action of so-called new social movements. It is of key importance for his theory the elaboration of the idea of recognition and status regarding the inclusion of the political dimension in the idea of parity of participation. Both, however, have been developed during the elaboration of the theory, giving it new life, but also presenting new challenges. To make a systematic balance of this formulation is necessary to try to understand the propositions of Fraser from his latest model. We also emphasize some inroads, as the consideration of the concept of citizenship, to continue the debate on this important contribution.

    This paper presents data collected during a year-long field experiment (REVEAL II) in the Fraser Valley, British Columbia. The data are used to provide information regarding ambient visibility conditions and fine particle concentrations in the valley. Although average fine mass measured during...... REVEAL II was 8-9 mu g m(-3), the fine particle mass has high light-scattering efficiencies and the visual range is frequently below publicly defined acceptable levels. For example, data indicate that during the fall the visual range is frequently below 20 km even under favorable meteorological...... conditions. Source apportionment analyses of mass and particle light-scattering indicate motor vehicles may contribute as much as 40% of the fine particle mass in the central valley and up to one-third of the particle light-scattering.

    2013-08-01

    This study examines the capacity to support the cumulative effects assessment and management for watersheds. The research is set in the Lower Fraser River Basin, a densely populated sub-watershed in British Columbia's lower mainland. Eight requirements or requisites for the watershed cumulative effects assessment and management are applied to evaluate current capacity for implementation in the Lower Fraser, and to identify the areas in need of capacity development. Results show that advancing watershed cumulative effects assessment and management requires not only good science but also leadership in the coordination of monitoring programs, and in ensuring the appropriate incentives and penalties for engagement and nonengagement. The lack of leadership in this regard is the result of existing governance structures arranged around the political boundaries, which have produced over time multiple agencies and jurisdictional fragmentation. Notwithstanding this, we argue that the watershed is the most appropriate scale for assessing and managing the cumulative effects to complex ecosystems.

    Full Text Available Nancy Fraser delineou uma compreensão procedimental do reconhecimento que tem possibilidade de combater políticas estreitas de autenticidade de grupo. Jürgen Habermas enfatiza um modelo deliberativo e uma análise histórica da esfera pública, por meio de um aprendizado teórico que culminou em 1992, com Faktizität und Geltung. Pretendemos demonstrar, com base em Fraser e Habermas, que, diante de um contexto de exclusão do espaço público oficial, é necessário ampliar arenas discursivas, sob pena de reproduzirmos e mantermos as assimetrias dominantes. Fraser, em Scales of Justice, defende uma esfera pública transnacional na qual há uma rearticulação dos processos decisórios, superando as fronteiras dos estados nacionais territorialmente situados. Propugnamos analisar a evolução das concepções de esfera pública em Habermas e Fraser ao longo de suas trajetórias teóricas. Em Habermas, até 2011, havia uma ambiguidade que oscilava entre a abordagem fina de patriotismo constitucional e a concepção densa de autocompreensão europeia. Com efeito, pretendemos investigar como Habermas, em Sobre a constituição da Europa - um ensaio, Habermas soluciona tal ambiguidade em relação à compreensão de esfera pública, lecionando que os cidadãos, por meio da tecnologia digital e de padrões morais, avaliam as estruturas econômicas europeias, confrontando as instituições existentes com as exigências de uma justiça global. Sustentamos, com base em Habermas, que tais discussões devem ser efetivadas no interior de um Parlamento mundial composto de Estados e cidadãos.

    Full Text Available Two N-trihalomethylthio fungicides were detected in the atmosphere in the Lower Fraser Valley agricultural region of Canada. Captan was detected in both the particle and gas phase with a dominant particle phase fraction observed in both 2005 and 2006 (only total captan atmospheric concentrations were available for 2004. This provides the first evidence of particle transport as a significant atmospheric transport pathway for captan in an agricultural region in Canada. Weekly captan air concentrations reached maximum levels of 13.2 ng m-3 in June 2006, while for folpet total atmospheric levels were lower with maximum reaching 1.7 ng m-3 in August 2004 and generally <1 ng m3 in 2005 and 2006. Folpet is detected in the atmosphere although not previously reported in usage inventories. In the three years examined (2004–2006 captan concentrations observed a seasonal maximum in atmospheric concentrations during spring to early summer coinciding with expected peak usage period on crops in the Lower Fraser Valley agricultural region located in British Columbia, Canada. No usage data is available in Canada beyond 2003 but these seasonal trends show that captan remains a dominant pesticide used in this agricultural region with no decline in atmospheric concentrations during 2004–2006.

  3. Myoglobin in pelagic small cetaceans.

    1999-02-01

    Although myoglobin (Mb) is considered to contribute significantly to the oxygen and diving capacity of marine mammals, few data are available for cetaceans. Cetacean by-catch in the tuna driftnet fisheries in the Sulu Sea, Philippines, afforded the opportunity to examine Mb content and distribution, and to determine muscle mass composition, in Fraser's (Lagenodelphis hosei) and spinner (Stenella longirostris) dolphins and a pygmy killer whale (Feresa attenuata). Age was estimated by body length determination. Stomach contents were analyzed for the presence or absence of milk and solid foods. It was hypothesized (a) that Mb concentration ([Mb]) would be higher in Fraser's and spinner dolphins than in other small cetaceans because of the known mesopelagic distribution of their prey, (b) that [Mb] would vary among different muscles according to function during diving, and (c) that [Mb] would increase with age during development. The results were as follows. (1) Myoglobin concentrations of the longissimus muscle in adult Fraser's (6.8-7.2 g 100 g-1 muscle) and spinner (5-6 g 100 g-1 muscle) dolphins and in an immature pygmy killer whale (5.7 g 100 g-1 muscle) were higher than those reported previously for small cetaceans. (2) [Mb] varied significantly among the different muscle types in adult dolphins but not in calves; in adults, swimming muscles had significantly higher [Mb] than did non-swimming muscles, contained 82-86 % of total Mb, and constituted 75-80 % of total muscle mass. (3) Myoglobin concentrations in Fraser's and spinner dolphins increased with size and age and were 3-4 times greater in adults than in calves. The high Mb concentrations measured in the primary locomotory muscles of these pelagic dolphins are consistent with the known mesopelagic foraging behaviour of Fraser's and spinner dolphins and suggest that the pygmy killer whale is also a deep-diving species. The high Mb concentrations in epaxial, hypaxial and abdominal muscle groups also support

    Top-predators play stabilising roles in island food webs, including Fraser Island, Australia. Subsidising generalist predators with human-sourced food could disrupt this balance, but has been proposed to improve the overall health of the island’s dingo (Canis lupus dingo) population, which is allegedly ‘starving’ or in ‘poor condition’. We assess this hypothesis by describing the diet and health of dingoes on Fraser Island from datasets collected between 2001 and 2015. Medium-sized mammals (such as bandicoots) and fish were the most common food items detected in dingo scat records. Stomach contents records revealed additional information on diet, such as the occurrence of human-sourced foods. Trail camera records highlighted dingo utilisation of stranded marine fauna, particularly turtles and whales. Mean adult body weights were higher than the national average, body condition scores and abundant-excessive fat reserves indicated a generally ideal-heavy physical condition, and parasite loads were low and comparable to other dingo populations. These data do not support hypotheses that Fraser Island dingoes have restricted diets or are in poor physical condition. Rather, they indicate that dingoes on Fraser Island are capable of exploiting a diverse array of food sources which contributes to the vast majority of dingoes being of good-excellent physical condition.

  7. Biodiveristy and Stability of Aboriginal Salmon Fisheries in the Fraser River Watershed

    2015-12-01

    Natural watersheds are hierarchical networks that may confer stability to ecosystem functions through integration of upstream biodiversity, whereby upstream asset diversification stabilizes the aggregate downstream through the portfolio effect. Here we show that riverine structure and its associated diversity confer stability of salmon catch and lengthened fishing seasons for Aboriginal fisheries on the Fraser River (1370km) in BC, Canada, the second longest dam-free salmon migration route in North America. In Canada, Aboriginal people have rights to fish for food, social, and ceremonial (FSC) purposes. FSC fisheries are located throughout the Fraser watershed and have access to varying levels of salmon diversity based on their location. For instance, fisheries at the mouth of the river have access to all of the salmon that spawn throughout the entire watershed, thus integrating across the complete diversity profile of the entire river. In contrast, fisheries in the headwaters have access to fewer salmon species and populations and thus fish from a much less diverse portfolio. These spatial gradients of diversity within watersheds provide a natural contrast for quantifying the effects of different types of diversity on interannual resource stability and seasonal availability. We acquired weekly and yearly catch totals from 1983 to 2012 (30 years) for Chinook, chum, coho, pink, and sockeye salmon for 21 FSC fishing sites throughout the Fraser River watershed from Fisheries and Oceans Canada. We examined how both population- and species-level diversity affects catch stability and season length at each site by quantifying year-to-year variability and within-year season length respectively. Salmon species diversity made fisheries up to 28% more stable in their catch than predicted with 3.7 more weeks to fish on average. Fisheries with access to high population diversity had up to 3.8 times more stable catch and 3 times longer seasons than less diverse fisheries. We

  8. In vitro propagation of fraser photinia using Azospirillum-mediated root development.

    2013-01-01

    Fraser photinia (Photinia × fraseri Dress.) is a woody plant of high ornamental value. The traditional propagation system for photinia is by rooting apical cuttings using highly concentrated auxin treatments. However, photinia micropropagation is an effective alternative to traditional in vivo propagation which is affected by the seasonal supply of cuttings, the long time required to obtain new plants, and the difficulties in rooting some clones.A protocol for in vitro propagation of fraser photinia using the plant growth-promoting ability of some rhizobacteria is described here. Bacterial inoculation is a new tool in micropropagation protocols that improves plant development in in vitro culture. Shoots culture on a medium containing MS macro- and microelements, Gamborg's vitamins (BM), N (6)-benzyladenine (BA, 11.1 μM), and gibberellic acid (1.3 μM) produce well-established explants. Proliferation on BM medium supplemented with 4.4 μM BA results in four times the number of shoots per initial shoot that develops monthly. Consequently, there is a continuous supply of plant material since shoot production is independent of season. Azospirillum brasilense inoculation, after 49.2 μM indole-3-butyric acid pulse treatment, stimulates early rooting of photinia shoots and produces significant increase in root fresh and dry weights, root surface area, and shoot fresh and dry weights in comparison with controls. Furthermore, inoculated in vitro photinia plants show anatomical and morphological changes that might lead to better adaptation in ex vitro conditions after transplanting, compared with the control plants.

    2007-12-01

    Metro Vancouver conducts an emission inventory for the Lower Fraser Valley on a five year basis. This report presented an estimate of the nonroad engine fleet population and emissions in the Canadian portion of the Lower Fraser Valley (CLFV). The nonroad engine fleet includes internal combustion engines of different fuel types used in mobile equipment such as on-road vehicles, aircraft, locomotives and ocean-going marine vessels. Some examples of nonroad equipment that were estimated included agricultural tractors; airport ground equipment; forklifts; excavators; generator sets; lawn mowers; railroad maintenance equipment; pleasure boats; and off-road motorcycles. The purpose of the study was to assist Metro Vancouver and other levels of government in determining what progress has been made in improving air quality, as well as the effect of policies and regulations on the environment in terms of nonroad vehicles. The report presented the objectives of the nonroad engine fleet characterization project which were to review the current data on nonroad engine populations and associated information, and confirm or improve the data through appropriate means; prepare estimates of 2005 emissions in the CLFV based on the revised engine counts using the United States Environmental Protection Agency's nonroad 2005 model; and prepare backcasts and forecasts of the 2005 nonroad engine emission estimates for 1990 to 2030 in five-year increments. Results were presented and analysed into the following 9 equipment type categories: agricultural, airport ground support, commercial, construction, industrial, lawn and garden, railway maintenance, recreational marine and recreational off-road vehicle. Four fuel types were considered for each type of equipment, notably gasoline, diesel, liquefied petroleum gases and compressed natural gas. The report described the methodologies and sources and presented the equipment population data. Emission results for carbon monoxide, nitrogen oxides

  12. Evaluating uncertainties in modelling the snow hydrology of the Fraser River Basin, British Columbia, Canada

    Islam, Siraj Ul; Déry, Stephen J.

    2017-03-01

    This study evaluates predictive uncertainties in the snow hydrology of the Fraser River Basin (FRB) of British Columbia (BC), Canada, using the Variable Infiltration Capacity (VIC) model forced with several high-resolution gridded climate datasets. These datasets include the Canadian Precipitation Analysis and the thin-plate smoothing splines (ANUSPLIN), North American Regional Reanalysis (NARR), University of Washington (UW) and Pacific Climate Impacts Consortium (PCIC) gridded products. Uncertainties are evaluated at different stages of the VIC implementation, starting with the driving datasets, optimization of model parameters, and model calibration during cool and warm phases of the Pacific Decadal Oscillation (PDO). The inter-comparison of the forcing datasets (precipitation and air temperature) and their VIC simulations (snow water equivalent - SWE - and runoff) reveals widespread differences over the FRB, especially in mountainous regions. The ANUSPLIN precipitation shows a considerable dry bias in the Rocky Mountains, whereas the NARR winter air temperature is 2 °C warmer than the other datasets over most of the FRB. In the VIC simulations, the elevation-dependent changes in the maximum SWE (maxSWE) are more prominent at higher elevations of the Rocky Mountains, where the PCIC-VIC simulation accumulates too much SWE and ANUSPLIN-VIC yields an underestimation. Additionally, at each elevation range, the day of maxSWE varies from 10 to 20 days between the VIC simulations. The snow melting season begins early in the NARR-VIC simulation, whereas the PCIC-VIC simulation delays the melting, indicating seasonal uncertainty in SWE simulations. When compared with the observed runoff for the Fraser River main stem at Hope, BC, the ANUSPLIN-VIC simulation shows considerable underestimation of runoff throughout the water year owing to reduced precipitation in the ANUSPLIN forcing dataset. The NARR-VIC simulation yields more winter and spring runoff and earlier decline

    Full Text Available O debate entre Nancy Fraser e Axel Honneth sobre redistribuição e reconhecimento abarca uma multiplicidade de questões. Tomando como fio condutor a pergunta acerca da possibilidade de compreender o conjunto de injustiças existentes a partir do conceito de reconhecimento ou da necessidade de recorrer, para isso, ao par conceitual redistribuição e reconhecimento, este artigo tem como objetivo defender que a disputa entre o monismo de Honneth e o dualismo de Fraser remete a discordâncias em suas teorias sociais. A partir de uma reconstrução das críticas dirigidas pelos autores ao dualismo social de Jürgen Habermas, bem como das diferentes teorias sociais que desenvolvem com o intuito de resolvê-las, procuraremos também mostrar que as saídas encontradas por eles a essas dificuldades estão no centro do debate sobre redistribuição e reconhecimento e que Fraser, ao desenvolver um dualismo social perspectivo, adota uma posição intermediária àquelas sustentadas por Honneth e Habermas.

  16. Streamwater Chemistry and Nutrient Export During Five Years of Bark Beetle Infestation of Subalpine Watersheds at the Fraser Experimental Forest

    Science.gov (United States)

    Rhoades, C.; Elder, K.; Hubbard, R.; Porth, L.

    2008-12-01

    Forested watersheds of western North America are currently undergoing rapid and extensive canopy mortality caused by a variety of insect species. The mountain pine bark beetle (Dendroctonus ponderosae) began to attack lodgepole pine (Pinus contorta) at the USFS Fraser Experimental Forest in central Colorado in 2002. By 2007, bark beetles had killed 78% of the overstory pine in Fraser research watersheds on average. The hydrologic, climatic, biogeochemical and vegetation records at the Fraser Experimental Forest provide a unique opportunity to quantify the impacts of this widespread, but poorly understood forest disturbance relative to a multi-decade pre-disturbance period. Here we compare seasonal streamwater chemistry and annual nutrient export for the five years since the bark beetle outbreak began with the pre- attack record. Patterns in post-outbreak streamwater biogeochemistry are compared to changes is species composition and proportional loss of overstory basal area for four basins. The influence of the outbreak will depend upon an aggregate of short (i.e. halted overstory water and nutrient use) and longer-term (i.e. altered canopy interception, windthrow, and understory growth) processes, so the hydrologic and biogeochemical implications of current beetle activity will not be fully realized for decades.

    Full Text Available Nancy Fraser, American philosopher, argues that claims for recognition of difference push at present, many social conflicts in the world and cover a wide range of aspirations, from the emancipation to the more openly roundly rejected. This multiplicity of movements seeking to express their demands through the language of recognition. 66 María Nohemí González Civilizar 10 (18: 65-74, enero-junio de 2010 Today, the claim of identity supplants class interest and makes it the best means of social mobilization. This new vision requires to Guild an intellectual and practical enterprise, which must be the dissolution of the concept of identity as a category of social analysis. The author proposes the model’s status as an alternative model in this configuration. What requires recognition is not group-specific identity but the status of individual members of a group as full participants in social interaction. To participate fully in a social group requires a new model of justice that has the capacity to sustain the lack of recognition and cultural value can not be understood apart from economic conditions and can not block the distribution of wealth. Also economic reasons, such as income distribution, counts as subtext for the recognition. Only considering both dimensions simultaneously it is possible to determine what prevents equal participation in a particular case. This is achieved by analyzing the overlap between recognition and redistribution to determine what is the best way to remedy the injustice.

    In this study we use the very extensive data-set on temporal and spatial structure of the internal boundary layer on the Lower Faser Valley, Canada, collected during the so-called Pacific `93 field campaign, to study the ability of the simple applied model by Gryning and Batchvarova (1996) and the CSU-RAMS meso-scale model summarised in Pielke et al. (1992) to describe the development and variability of the internal boundary layer depth during the course of a day. Given the complexity of topography, coastline and land-use in the Lower Fraser Valley region, both models perform remarkably well. The simple applied model performs extremely well, given its simplicity. It is clear that correct specification of spatially resolved surface sensible heat flux and wind field are crucial to the success of this model which can be operated at very fine spatial resolution. The 3D model performs extremely well, though it too must capture the local wind field correctly for complete success. Its limited horizontal resolution results in strongly smoothed internal boundary layer height fields. (LN)

  19. Weak and strong publics: drawing on Nancy Fraser to explore parental participation in neonatal networks

    Abstract Aims  We draw on the work of Nancy Fraser, and in particular her concepts of weak and strong publics, to analyze the process of parental involvement in managed neonatal network boards. Background  Public involvement has moved beyond the individual level to include greater involvement of both patients and the public in governance. However, there is relatively little literature that explores the nature and outcomes of long‐term patient involvement initiatives or has attempted to theorize, particularly at the level of corporate decision making, the process of patient and public involvement. Methods  A repeated survey of all neonatal network managers in England was carried out in 2006–07 to capture developments and changes in parental representation over this time period. This elicited information about the current status of parent representation on neonatal network boards. Four networks were also selected as case studies. This involved interviews with key members of each network board, interviews with parent representatives, observation of meetings and access to board minutes. Results  Data collected show that a wide range of approaches to involving parents has been adopted. These range from decisions not to involve parents at this level to relatively well‐developed systems designed to link parent representatives on network boards to parents in neonatal units. Conclusion  Despite these variations, we suggest that parental participation within neonatal services remains an example of a weak public because the parent representatives had limited participation with little influence on decision making.

    Organochlorine compounds are highly persistent in the environment, causing bioaccumulation and biomagnification through the marine food chain. To verify the bioaccumulation pattern of DDT and its metabolites, as well as PCBs, Mirex, HCHs and HCB, samples of subcutaneous adipose tissue from 25 Guiana dolphins (Sotalia guianensis), two Fraser's dolphins (Lagenodelphis hosei), two spinner dolphins (Stenella longirostris), one spotted dolphin (Stenella frontalis), and one striped dolphin (Stenella coeruleoalba) were analyzed. The collected specimens were found stranded in northeastern Brazil between 2005 and 2011. The concentrations were reported in μg·g(-1) lip, varying from 0.02 to 17.3 for ΣPCB, from 0.003 to 5.19 for ΣDDT, from 0.005 to 0.16 for ΣHCH, from 0.002 to 0.16 for HCB, and from 0.02 to 2.38 for Mirex. The PCBs dominated the bioaccumulation pattern for both the Guiana and spinner dolphins; for the other species, DDT was the major compound. A discriminant function analysis revealed the differences in the organochlorine accumulation patterns between the Guiana dolphin (S. guianensis) and the continental shelf/oceanic dolphins (S. frontalis and S. longirostris). The results also show that the concentrations of organochlorine compounds found in the delphinids in northeastern Brazil were lower than the delphinids found in other regions of Brazil, as well as other locations worldwide with intense agroindustrial development and/or a larger population.

    Snowpack peak water equivalent (PWE), ion concentration, content, and spatial distribution of ion load data from spring 1987-1996 in a 1 ha clearcut and adjacent forested plots vegetated by mature Picea engelmannii and Abies lasiocarpa in the Fraser experimental forest (FEF), Colorado are presented. Our objectives were: (1) to see if a forest opening might redistribute snowfall, snowpack moisture, and snowpack chemical content, and (2) to examine the importance of canopy interception on snowpack quantity and chemistry. On an average, the canopy intercepted 36% of snowfall. Interception was correlated with snowfall amount, snowpack PWE beneath the canopy, and air temperature. Canopy removal increased snowpack PWE to >90% cumulative snowfall inputs. Snowpack K-, H-, and NH4+ concentrations on the clearcut were lower and NO3- higher than in the snowpack beneath the forested plots. Cu mulative snowfall K+ input was less than in the clearcut snowpack; H+ inputs were greater in snowfall than in the snowpack of any plot; and inorganic N (NO3- and NH4+) inputs from snowfall to the clearcut were greater than to the forested plots. Processes accounting for the differences between snowfall inputs and snowpack ion content were leaching of organic debris in the snowpack, differential elution of the snowpack, and canopy retention. There were significant trends by year in snowpack ion content at PWE without similar trends in snowfall inputs. This finding coupled with snowpack ion elution bring into question the use of snowpack chemistry as an indicator of winter atmospheric inputs in short-term studies. ?? 2001 Elsevier Science B.V.

    Emissions inventories are used by government agencies as a tool for policy development and air quality management. Marine vessels have been identified as a major source of anthropogenic pollution in British Columbia. This report presents estimates of emissions from marine vessels in coastal areas of British Columbia's Fraser Valley Regional District (FVRD) for the year 2000. The project includes an update of emission estimates for each marine vessel category and an update of emission estimates for pollutants of interest, including carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), sulphur oxides (SOx), volatile organic compounds (VOCs), as well as inhalable fine particulates (PM10 and PM2.5) and greenhouse gases such as carbon dioxide, methane, nitrous oxide and ammonia. This report presents both spatial and temporal allocation of emissions. Results indicate that ocean-going vessels are the major contributor to emissions of NOx, SOx, PM and greenhouse gases, accounting for 58, 95, 82, and 58 per cent of the total marine vessel emissions respectively. They also contribute 14 per cent to the marine totals for CO and VOCs. Harbour vessels contribute 28 and 27 per cent of NOx and greenhouse gases and 10 per cent or less to all other contaminant totals. Ferries contribute between 2 per cent and 13 per cent for to each contaminant, including 13 per cent of NOx, 12 per cent of greenhouse gases, and 6 per cent of CO. Fishing vessels contribute 1 per cent or less of all contaminants. Although recreational vessels are major contributors for CO and VOC, they contribute less than 10 per cent for all other contaminants. A comparison of 1993 and 2000 marine vessel inventory for British Columbia was presented and recommendations for improvements were presented. refs., tabs., figs

    The Greater Vancouver area has been experiencing common episodes of poor visibility as a result of urban and agricultural sources of emissions. A study was conducted to determine the response of tourists in the Vancouver and Lower Fraser Valley Regions to visible air quality and to estimate the potential losses in tourist revenue due to poor visibility episodes. This was accomplished using an interactive survey of tourists in 1999. The results were statistically analyzed to develop visibility response functions. A simple economic model based on the visibility response function was then created to predict losses in tourist revenue. The group of tourists were shown four photographic slides of the Valley and Vancouver area depicting various stages of degradation in visibility. They were asked to rate each slide as either acceptable or unacceptable (if they would not make a return visit). Unacceptability rates for the four camera locations were statistically analyzed. The effect of clouds and the measurable visibility parameter was examined. The model predicts future tourist revenue losses in the amount of $7.45 million for the Greater Vancouver Area and $1.32 million in the Fraser Valley. It was recommended that further research should be conducted with more camera locations to provide a wider variety of viewpoints for assessment. This study can provide direction in setting policies to improve visibility in the region. 25 refs., 20 tabs., 4 figs., 3 appendices.

    We use passive seismic and gravity data to characterize the crustal structure and the crust-mantle boundary of the east Albany-Fraser Orogen in Western Australia, a Proterozoic orogen that reworked the southern and southeastern margin of the Archean Yilgarn Craton. The crustal thickness pattern retrieved from receiver functions shows a belt of substantially thickened crust - about 10 km thicker than the surrounding regions - that follows the trend of the orogen, but narrows to the southwest. Common conversion point profiles show a clear transition from a wide, symmetric Moho trough in the northeast to a one-sided, north-western Moho dip in the southwest, where the Moho appears to underthrust the craton towards its interior. The change from a Moho trough to an underthrust Moho appears to coincide with the inferred trace of the Ida Fault, a major terrane boundary within the Yilgarn Craton. Bulk crustal vp/vs ratios are mostly in the felsic to intermediate range, with clearly elevated values (≥1.8) at stations in the Fraser Zone granulite facies, dominantly mafic metamorphic rocks. Forward modelling of gravity anomaly data using the retrieved Moho geometry as a geometric constraint shows that a conspicuous, elongated gravity low on the northwestern side of the eastern Albany-Fraser Orogen is almost certainly caused by thickened Archean crust. To obtain a model that resembles the regional gravity pattern the following assumptions are necessary: high-density rocks occur in the upper crustal portion of the Fraser Zone, at depth inside the Moho trough and in parts of the eastern Nornalup Zone east of the Moho trough. Although our gravity models do not constrain at which crustal level these high-density rocks occur, active deep seismic surveys suggest that large extents of the east Albany-Fraser Orogen's lower crust include a Mesoproterozoic magmatic underplate known as the Gunnadorrah Seismic Province. The simplest interpretation of the imaged crustal structure is that

    Full text: Pleistocene lake sediments from a relic perched freshwater lake on Fraser Island have been found to date back to ca.600 ka using U/Th analysis of the organics. This sequence is one of the three longest terrestrial records of environmental change in Australia and the contained evidence of vegetation, fire and lake level changes (Longmore and Heijnis, 1996) and is an invaluable contribution to palaeoclimatic reconstruction. A younger sequence, dated by conventional radiocarbon analysis, has 6.5 m of continuous organic sedimentation from ca. 30 ka to the present. The last 8.5 ka has been analysed in detail, showing a mid-Holocene `dry` period (Longmore, 1996). Continental aeolian dust from extreme wind erosional events has been measured in modern atmospheres (McTainsh, 1989; Knight et al., 1995) and deep sea cores (Hesse, 1994), but the terrestrial record of wind erosion during the Pleistocene is sparse. We will report on a pilot project to determine the presence of aeolian dust from extreme wind erosional events in the past in the sediments of Fraser Island lakes. Due to the highly weathered, well-sorted, siliceous nature of the dune sands forming the Island and the highly organic nature of the lake sediments (80-95% LOI), these are some of the few terrestrial sequences that permit separation of aeolian dust from local catchment materials. In the future, oxygen isotope and XRD analysis of the extracted dust will allow the most likely source of the entrained material to be determined and thus provide further evidence as to the wind regime during the last 600ka and 30ka respectively. The separation of dust from these terrestrial sequences is a major achievement and potentially may make a significant contribution to global palaeoclimatic models. Paper no. 78. 5 refs.

    Full Text Available O debate sobre os direitos das uniões homoafetivas constitui um dos tópicos mais controversos do direito constitucional. Como se sabe, a união homoafetiva não foi reconhecida expressamente no § 3º do artigo 226 da CF, inexistindo norma específica. O presente artigo pretende investigar a posição de ministros do STF em relação ao tema das uniões homoafetivas, em conexão com as filosofias do reconhecimento propostas por Axel Honneth e Nancy Fraser. Nesse sentido, os fundamentos filosóficos das teorias do reconhecimento podem ser um instrumental teórico fundamental para a compreensão de determinadas formas de ativismo judicial que objetivam a proteção de minorias estigmatizadas cujas pretensões normativas são desconsideradas pelo processo político. Pretendemos demonstrar que o paradigma da autorrealização proposto por Honneth é impreciso e incapaz de legitimar formas de ativismo judicial voltadas para a proteção dos direitos das uniões homoafetivas.The homosexual union rights are debated as one of the most controversial topics of Constitutional Law. It is known that the homosexual union was not explicitly recognized by the article 226 § 3º from FC, as there is no specific regulation for this subject. This paper intends to investigate STF ministers' position in relation to homosexual union according to Axel Honneth and Nancy Fraser philosophies of recognition. In this sense, the philosophical basis from recognition theories may be a theoretical instrument to comprehend some forms of judicial activism which aims are to protect stigmatized minorities whose regulatory intentions are disregarded by the political process. We intend to demonstrate that the Honneth's paradigm of achievement is imprecise and can't legitimate forms of judicial activism aimed to protect the rights of homosexual unions.

    2003-09-01

    The 2002 Graham Fraser Memorial Lecture deals first with the French origins of cochlear implantation in Paris in the 1950s and the role of André Djourno and Charles Eyriès. Following this work in Paris Dr William House in Los Angeles continued work on cochlear implants and, subsequently, experimental implant programmes were started in California, Paris, Vienna and Melbourne. The next section of this lecture covers the experimental work of Galvani in establishing the role of electricity in physiology. The results of his first experiments were published in 1791, the year that Mondini produced the first account of a cochlear malformation in a congenitally deaf child. At around the same time sign language for congenitally deaf children was being developed for the first time in Paris by Epée and the first disputes occurred between oralists and those who promoted signing for the education of congenitally deaf children. In a present day cochlear implant programme good results from implanting congenitally deaf children at an early age and implanting adults who have become profoundly deaf are now taken for granted. We do have much to learn, however, from more complex implant candidates and some examples of such candidates are presented. Lastly, looking to the future, the use of PET scanning to try and gain information about how the brain handles the information provided to it by a cochlear implant is described.

    2001-01-01

    This document presents a newly drafted growth strategy developed by the Fraser Valley Regional District (FVRD) in British Columbia. It guides the sustainable growth, change and development of the region for the next 25 years and deals with air pollution, water quality, traffic congestion, affordable housing, employment, energy use, parks and green space. In particular, this case study develops a method to apply full cost accounting (FCA) to a growth strategy. FCA is the most appropriate way to approach a sustainable strategy because it considers economic, social and environmental issues. The study also includes the development of a software tool consisting of an ACCESS database and an ARCVIEW GIS file for compiling and analyzing detailed infrastructure profiles which can be used to assess the full costs of different growth scenarios. The following four issue categories of environmental and economic indicators of FVRD performance were addressed: solid waste, water and wastewater, energy, and infrastructure costs. Each issue category was then used to establish a set of 5 performance indicators that can be measured and assessed over time. These included solid waste, water consumption, wastewater, energy consumption and air emissions. The database and methodology developed for this project is suitable for other regions.

    2000-03-01

    Three years of hourly averaged PM10 (particulate matter less than 10 microns in diameter) tapered element oscillating microbalance (TEOM) data from 10 sites in the large coastal valley incorporating Greater Vancouver were used to investigate the spatiotemporal dimensions and air pollution meteorology of particulate pollution. During the period studied, the provincial "acceptable" objective daily concentration of 50 micrograms m-3 was exceeded at 7 of the 10 sites. The highest annual, seasonal, and maximum hourly concentrations were recorded at Abbotsford in the central valley. Mean seasonal PM10 concentrations were highest in the wintertime in the western Lower Fraser Valley (LFV) and in the summertime at the central and eastern valley locations. Within the network, interstation correlations of daily average concentrations exceed 0.8 at interstation distances less than 20 km and decrease thereafter. For daily maximum concentrations (hourly), interstation correlations decrease sharply with distance. Meteorological conditions responsible for elevated particulate concentrations in the LFV are associated with (1) short periods (1- to 3-hr duration) of reduced dispersion during summer nights at sites close to primary sources, (2) summer anticyclonic conditions when photochemical pollutant concentrations build up across the entire valley, and (3) occasional wintertime "gap wind" events in the eastern valley.

    Highlights: • Muscular δ 13 C and δ 15 N data of cetaceans were used to identify their ecological niche • Inshore–offshore distribution pattern was found for four sympatric neritic odontocetes. • Horizontal and vertical movements found in sympatric odontocetes as they grow. • Taiwan’s Chinese white dolphins is an exclusive fish eater. • Prey-derived As- and Cd-induced health threats were found for some dolphins. - Abstract: A total of 24 stranded or bycatch cetaceans, including Balaenoptera omurai, Lagenodelphis hosei, Kogia sima, Stenella attenuata, Grampus griseus, Neophocaena phocaenoides, and Sousa chinensis, were collected from 2001 to 2011 in Taiwan. Using the muscular δ 13 C and δ 15 N data, three ecological groups were identified as the oceanic baleen whale, the neritic, and the coastal toothed whale groups, coinciding with their taxonomy, feeding habits and geographical distribution. A horizontal inshore to offshore distribution was found for the sympatric neritic toothed dolphins, G. griseus, K. sima, S. attenuata, and L. hosei in the outermost offshore waters, accompanying their growth. For the first time we identify Taiwan’s Chinese white dolphin, S. chinensis, as an exclusive fish eater. Cd and As bioaccumulated in the G. griseus, L. hosei and S. attenuata increase as they grow. Prey-derived As- and Cd-induced health threats were found in L. hosei, and G. griseus

    A web-based questionnaire-survey was administered primarily to determine what information is useful to managers in Fraser Health, of British Columbia to support decision-making for workplace health and safety. The results indicated that managers prefer electronic quarterly reports, with targets, goals, and historical trends rated as "very important." Over 85.7% "agree" that if information was readily available in the "most beneficial" format, they would be able to improve workplace health. Recommendations include that managers be presented with clear and concise workplace health reports that facilitate analysis for decision-making.

    Two Aerodyne Aerosol Mass Spectrometers (AMS) were deployed at three sites representing urban, semi-rural and rural areas during the Pacific 2001 experiment in the Lower Fraser Valley (LFV), British Columbia, Canada in August 2001. The AMS provides on-line quantitative measurements of the size and chemical composition of the non-refractory fraction of submicron aerosol particles. A significant accumulation mode with a peak around 400-500 nm was observed at all sites that was principally composed of sulphate, organics, ammonium and some nitrate. Another significant mode with a peak below 200 nm was also observed at the urban site and when urban plumes affected the other sites. This paper focuses on the variability of the organic particulate composition and size distribution as a function of location and photochemical activity with a particular emphasis on the urban and rural areas. The small organic mode at the urban site was well correlated with gas phase CO, 1,3-butadiene, benzene and toluene with Pearson's r values of 0.76, 0.71, 0.79 and 0.69, respectively, suggesting that combustion-related emissions are likely to be the main source of the small organic mode at this site. The mass spectra of the urban organic particulate are similar to those of internal combustion engine lubricating oil, and of diesel exhaust aerosol particles, implying that they were composed of a mixture of n-alkanes, branched alkanes, cycloalkanes, and aromatics. In contrast, organic particulate at the rural site was dominated by shorter chain oxidized organic compounds. Correlations between the two organic modes and gas phase compounds at the rural site indicated that a significant part of the small mode originated from combustion sources, while the large accumulation organic mode appeared to be the result of photochemical processing. Processing of organic particulate during a relatively high O3 episode at the rural site appeared to increase the modal diameter of the accumulation mode from

Hodges à luz dos referenciais teóricos desenvolvidos por Axel Honneth e Nancy Fraser e seus reflexos na interpretação e na crítica de posturas proativas do Poder Judiciário. Sustenta-se que o voto de Justice Kennedy contempla um conjunto de discursos implícitos que não apenas estabelecem a subordinação de status de casais homossexuais não casados - que é tão criticada por Fraser - mas essencializam a identidade gay. Utiliza-se o método de indução analítica e a análise crítica do discurso feminista. Outrossim, o trabalho também emprega a documentação indireta.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2016v15n1p126 Este artigo reconstrói a tese de Fraser acerca de uma justiça bidimensional apresentada como uma alternativa para o dilema redistribuição-reconhecimento. O modelo de justiça da redistribuição inspirado em Karl Marx defende a tese que as injustiças têm um fundo econômico e que só serão devidamente solucionadas a partir do enfrentamento das desigualdades sociais. O modelo de justiça do reconhecimento inspirado em Hegel e atualmente defendido por Honneth acredita que as injustiças são gestadas a partir de questões concernentes a padrões culturais excludentes que negam status de reconhecimento de modo especial a negros, gays e mulheres. Para Nancy Fraser, os indivíduos sofrem injustiças ligadas a desigualdades sociais, econômicas e culturais. Uma teoria da justiça para obter o devido êxito deve confrontar elementos vinculados tanto à redistribuição quanto ao reconhecimento.

  2. Two attempts at grounding social critique in „ordinary“ actors’ perspectives: The critical theories of Nancy Fraser and Axel Honneth

    2014-01-01

    Full Text Available This paper analyzes two contemporary, „third-generation“ perspectives within critical theory - Nancy Fraser’s and Axel Honneth’s - with the aim of examining the degree to which the two authors succeed in grounding the normative criteria of social critique in the perspectives of ’ordinary’ social actors, as opposed to speculative social theory. To that end, the author focuses on the influential debate between Fraser and Honneth Redistribution or Recognition? which concerns the appropriate normative foundations of a „post-metaphysical“ critical theory, and attempts to reconstruct the fundamental 29 disagreements between Fraser and Honneth over the meaning and tasks of critical theory. The author concludes that both critical theorists ultimately secure the normative foundations of critique through substantive theorizations of the social, which frame the two authors’ „reconstructions“ of the normativity of everyday social action, but argues that post-metaphysical critical theory does not have to abandon comprehensive social theory in order to be epistmologically „non-authoritarian“.

    We have interpreted a ~1 pulse/m2 lidar survey (acquired in 2006 in leaf-on conditions under contract to the USGS) to construct a geomorphic map of western Whatcom County. The new lidar data reveal the existence of previously unrecognized landforms. Within this landscape, we see these features that reflect a rich post-LGM history: Glacial: Ice contact deposits interpreted as moraines reveal at least 8 successive moraines associated with the late Pleistocene Fraser Glaciation. At least two of the moraine crests were formed during ice re- advance; others may mark stillstands during ice retreat. All are older than about 10,250 14C yrs BP, based on basal peat from a kettle in outwash associated with the youngest moraine. Marine: Extensive and successive fossil shorelines, wave-cut notches, wave-washed surfaces, down- slope truncation of gullies, and deltas along the fringe of uplands surrounding the SW Fraser Lowland document former relative sea level and probable glacioisostatic tilting. The highest shorelines are at nearly 150 m above sea level. Some shorelines are cut into moraines, while others are truncated by them. Uplifted back-beach surfaces of likely mid-Holocene age at Birch Bay and Neptune Beach (elevations ~1 m and ~3 m higher than modern back-beach surfaces) suggest Holocene uplift. Glaciofluvial: Large, stepped, sediment wave bed-forms, with wavelengths of 430 to 850 m and heights from 1 to 3.5 m, record deposition associated with high discharge and rapid water release. Sub-parallel, narrow scour troughs are up to 4 km in length and 8 m in depth. These high energy geomorphic features record at least three large discharge events. Their apparent associations with former ice margins indicate that they are the result of outburst floods. Multiple outwash surfaces in the lowland are also related to former ice margins. Fluvial: At present the Nooksack River flows west from the town of Everson and reaches Bellingham Bay just south of Ferndale. Relatively low

    2007-03-01

    Full Text Available Scholarly data, such as academic articles, research reports and theses/dissertations, traditionally have limited dissemination in that they generally require journal subscription or affiliation with particular libraries. The notion of open access, made possible by rapidly advancing digital technologies, aims to break the limitations that hinder academic developments and information exchange. This paper presents the Electronic Thesis & Dissertation (ETD Project at the Simon Fraser University Library, British Columbia, Canada, and discusses various technological considerations associated with the Project including selection of software, capture of metadata, and long-term preservation of the digitized data. The paper concludes that a well-established project plan that takes into account not only technological issues but also issues relating to project policies, procedures, and copyright permissions that occur in the process of providing open access plays a vital role for the overall success of such projects.

  6. Implications of ammonia emissions for fine aerosol formation and visibility impairment. A case study from the Lower Fraser Valley, British Columbia

    Ammonia enhances atmospheric aerosol formation and, once in the aerosol form, enhances the light extinction characteristics of those aerosols. In this paper, an ammonia emissions inventory is developed for the Lower Fraser Valley (LFV) of British Columbia and used in conjunction with ambient...... ammonia and ammonium measurements to explain: (i) the observed temporal and spatial variability of fine inorganic aerosol composition and concentrations in the valley, and (ii) the severity and spatial variability of visibility degradation in the LFV. It is proposed here that advection of urban emissions...... of nitrogen and sulphur oxides over agricultural areas in the eastern and central valley with higher ammonia emissions favours subsequent ammonium nitrate and sulphate formation. This leads to higher fine mass concentrations and lowest visibility in the predominantly agricultural regions of the valley. (C...

    Congenital anomalies of the kidney and urinary tract (CAKUT) are the most common cause (40–50%) of chronic kidney disease (CKD) in children. About 40 monogenic causes of CAKUT have so far been discovered. To date less than 20% of CAKUT cases can be explained by mutations in these 40 genes. To identify additional monogenic causes of CAKUT, we performed whole exome sequencing (WES) and homozygosity mapping (HM) in a patient with CAKUT from Indian origin and consanguineous descent. We identified a homozygous missense mutation (c.1336C>T, p.Arg446Cys) in the gene Von Willebrand factor A domain containing 2 (VWA2). With immunohistochemistry studies on kidneys of newborn (P1) mice, we show that Vwa2 and Fraser extracellular matrix complex subunit 1 (Fras1) co-localize in the nephrogenic zone of the renal cortex. We identified a pronounced expression of Vwa2 in the basement membrane of the ureteric bud (UB) and derivatives of the metanephric mesenchyme (MM). By applying in vitro assays, we demonstrate that the Arg446Cys mutation decreases translocation of monomeric VWA2 protein and increases translocation of aggregated VWA2 protein into the extracellular space. This is potentially due to the additional, unpaired cysteine residue in the mutated protein that is used for intermolecular disulfide bond formation. VWA2 is a known, direct interactor of FRAS1 of the Fraser-Complex (FC). FC-encoding genes and interacting proteins have previously been implicated in the pathogenesis of syndromic and/or isolated CAKUT phenotypes in humans. VWA2 therefore constitutes a very strong candidate in the search for novel CAKUT-causing genes. Our results from in vitro experiments indicate a dose-dependent neomorphic effect of the Arg446Cys homozygous mutation in VWA2. PMID:29351342

    Full Text Available This article analyzes the text of all rules regarding logging performed by traditional populations within the community and family forest management policy in order to determine whether, besides the search for income generation, differentiated socio-cultural conditions of the group are considered in that policy. The work is developed from the perspective of the theory of justice advocated by political philosopher Nancy Fraser through the work "From Redistribution to Recognition? Dilemmas of justice in a "post-socialist"", and it analyses national and international related legislation is analyzed, and conducted literature to build the theoretical framework of the current reality of community forest management. We conclude that, although it seeks to ensure access to income to traditionalpopulations through logging, the main standards of community forestry are marked by traits and requirements that despise differentiated culture of those groups, which have made impossible economic guarantees by activity. This way, the traditional populations are identified as bivalent collectives that require redistribution of economic and social wealth, while simultaneously recognizing their cultural identity to assure fair policies, which requires, in such a way, the current model of community forestry.

    We investigated chlorinated hydrocarbon contaminants in aquatic mustelid species on the Fraser and Columbia Rivers of northwestern North America. Carcasses of river otter (Lutra canadensis) (N=24) and mink (Mustela vison) (N=34) were obtained from commercial trappers during the winters of 1990-91 and 1991a??92. Pooled liver samples were analyzed for organochlorine pesticides, polychlorinated biphenyls (PCBs), including non-ortho congeners, polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs). Most samples contained detectable concentrations of DDE, PCBs, although there was substantial variability in patterns and trends among neighboring samples. Concentrations of DDE were in some mink and several otter samples from the lower Columbia River elevated (to 4700 g/kg wet weight); excluding one mink sample from the Wenatchee area, mean DDE levels generally decreased between 1978a??79 and 1990a??92. PCBs were present in all samples. PCB concentrations in otter livers collected from the lower Columbia were ten-fold lower than measured a decade previously; nevertheless, a sample taken near Portland had a mean concentration of 1500 g/kg, within a range of concentrations associated with reproductive effects in captive mink. Concentrations of 2,3,7,8-TCDD and TCDF were generally below detection limits, except for one otter collected near a pulp mill at Castlegar, on the upper Columbia, with 11 ng TCDD/kg in liver. Elevated concentrations of higher chlorinated PCDD/Fs, probably resulting from use of chlorophenolic wood preservatives, were found in both species; one otter sample from the lower Columbia had 2200 ng OCDD/kg. International TCDD toxic equivalent levels in mink (31 ng/kg) and otter (93 ng/kg) from the lower Columbia River approached toxicity thresholds for effects on reproduction in ranch mink.

    Visibility degradation, one of the most noticeable indicators of poor air quality, can occur despite relatively low levels of particulate matter when the risk to human health is low. The availability of timely and reliable visibility forecasts can provide a more comprehensive understanding of the anticipated air quality conditions to better inform local jurisdictions and the public. This paper describes the development of a visibility forecasting modelling framework, which leverages the existing air quality and meteorological forecasts from Canada's operational Regional Air Quality Deterministic Prediction System (RAQDPS) for the Lower Fraser Valley of British Columbia. A baseline model (GM-IMPROVE) was constructed using the revised IMPROVE algorithm based on unprocessed forecasts from the RAQDPS. Three additional prototypes (UMOS-HYB, GM-MLR, GM-RF) were also developed and assessed for forecast performance of up to 48 hour lead time during various air quality and meteorological conditions. Forecast performance was assessed by examining their ability to provide both numerical and categorical forecasts in the form of 1-hr total extinction and Visual Air Quality Ratings (VAQR), respectively. While GM-IMPROVE generally overestimated extinction over twofold, it had skill in forecasting the relative species contribution to visibility impairment, including ammonium sulphate and ammonium nitrate. Both statistical prototypes, GM-MLR and GM-RF, performed well in forecasting 1-hr extinction during daylight hours, with correlation coefficients (R) ranging from 0.59 to 0.77. UMOS-HYB, a prototype based on post-processed air quality forecasts without additional statistical modelling, provided reasonable forecasts during most daylight hours. In terms of categorical forecasts, the best prototype was approximately 75 to 87% correct, when forecasting for a condensed three-category VAQR.

    In February 2004 a highly pathogenic avian influenza outbreak erupted in the Fraser Valley of British Columbia, Canada. The index farm was a chicken broiler breeder operation comprising two flocks, 24 and 52 wk of age. Birds in the older flock presented with a mild drop in egg production and a small increase in mortality. Pathological specimens taken from the older flock were submitted to the provincial veterinary diagnostic laboratory from which an influenza A virus was isolated. While still under investigation by the provincial veterinary authorities, a spike in mortality was observed in birds belonging to the younger flock. Diagnostic material from both flocks was forwarded to the Canadian Food Inspection Agency's National Centre for Foreign Animal Disease. A low-pathogenicity H7N3 virus was detected in the older flock and a novel highly pathogenic H7N3 virus was found in specimens collected from the younger flock. Despite destruction and disposal of birds on the index farm, the virus spread to adjacent farms. Given the high density of poultry operations in the Fraser Valley and the high level of integration amongst industry support services, a total of approximately 17 million chickens, turkeys, ducks, geese, and speciality birds were put at immediate risk. Despite movement controls the virus spread and established itself in three distinct clusters. To prevent further spread, healthy, marketable birds outside of the surveillance areas were pre-emptively slaughtered. Although highly pathogenic avian influenza is a federal responsibility, the successful control and eradication of this outbreak would not have been possible without the cooperative involvement of federal and provincial diagnostic laboratories. The success of this collaboration was partly responsible for the formation of a national avian influenza laboratory network.

    To investigate the foraging habitats of delphinids in southeastern Brazil, we analyzed stable carbon (δ(13)C) and nitrogen (δ(15)N) isotopes in muscle samples of the following 10 delphinid species: Sotalia guianensis, Stenella frontalis, Tursiops truncatus, Steno bredanensis, Pseudorca crassidens, Delphinus sp., Lagenodelphis hosei, Stenella attenuata, Stenella longirostris and Grampus griseus. We also compared the δ(13)C and δ(15)N values among four populations of S. guianensis. Variation in carbon isotope results from coast to ocean indicated that there was a significant decrease in δ(13)C values from estuarine dolphins to oceanic species. S. guianensis from Guanabara Bay had the highest mean δ(13)C value, while oceanic species showed significantly lower δ(13)C values. The highest δ(15)N values were observed for P. crassidens and T. truncatus, suggesting that these species occupy the highest trophic position among the delphinids studied here. The oceanic species S. attenuata, G. griseus and L. hosei had the lowest δ(15)N values. Stable isotope analysis showed that the three populations of S. guianensis in coastal bays had different δ(13)C values, but similar δ(15)N results. Guiana dolphins from Sepetiba and Ilha Grande bays had different foraging habitat, with specimens from Ilha Grande showing more negative δ(13)C values. This study provides further information on the feeding ecology of delphinids occurring in southeastern Brazil, with evidence of distinctive foraging habitats and the occupation of different ecological niches by these species in the study area.

    Two candidate method modifications for the Atlas Listeria Environmental LE Detection Assay were compared with the U.S. Department of Agriculture (USDA)-Food Safety and Inspection Service Microbiology Laboratory Guidebook 8.09 (MLG 8.09) method for detection of Listeria spp. on stainless steel, polyvinyl chloride (PVC), and sealed concrete surfaces. For LE candidate method 1, samples were enriched in FoodChek Actero Listeria Enrichment Media [ALEM; Performance Tested MethodSM (PTM) 111201] at 35 ± 2°C for 18 to 24 h and evaluated for a range of analytical sample volumes. For LE candidate method 2, the current Roka PTM using 90 mL of Half-Fraser broth for enrichment at 35 ± 2°C was evaluated at 24 h with a reduced sample volume. These comparisons were made in multiple studies across the three environmental surfaces. Within each method and study, a total of 5 samples were uninoculated, 20 samples were inoculated with Listeria spp. at a low level to target fractional positivity, and 5 samples were inoculated with Listeria spp. at a high level to approach a probability of detection of 1. Inclusivity and exclusivity studies were also conducted for the LE method in combination with Half-Fraser and ALEM. The Atlas Listeria Environmental LE Detection Assay detected all 50 inclusive organisms, including 25 strains of L. monocytogenes and 5 strains of each of the other five common species of Listeria (L. innocua, L. welshimeri, L. ivanovii, L. seeligeri, and L. grayi) and none of the 30 exclusive organisms across all media and with both 200 and 2000 µL sample volumes. For the LE candidate method 1 studies, no significant differences were observed within the Roka ALEM method at 18, 20, or 24 h and for both the 200 and 2000 µL sample volumes as compared with the paired culture outcome. However, the ALEM method performed significantly better as compared with the unpaired reference method for sealed concrete and stainless steel. For the LE candidate method 2 studies, no

    This study represents the first survey of the parasitic fauna of cetaceans off the northeastern coast of Brazil. Parasites were collected from 82 animals rescued from the states of Ceará to Bahia, including the archipelago of Fernando de Noronha. A total of 14 species of cetaceans were evaluated: Sotalia guianensis, Stenella sp., Stenella clymene, Stenella longirostris, Stenella coeruleoalba, Stenella frontalis, Megaptera novaeangliae, Peponocephala electra, Steno bredanensis, Kogia breviceps, Kogia sima, Globicephala macrorhynchus, Tursiops truncatus, Physeter macrocephalus and Lagenodelphis hosei. The parasites were fixed and preserved in 70% ethanol or alcohol-formalin-acetic acid solution (AFA), clarified in phenol and mounted on slides for morphological identification. In total, 11 species and 8 genera of endo- and ectoparasites were identified: Halocercus brasiliensis, Halocercus kleinenbergi, Stenurus globicephalae, Halocercus sp., Anisakis sp., Crassicauda sp. (Nematoda), Phyllobothrium delphini, Monorygma grimaldii, Scolex pleuronectis, Strobicephalus triangularis, Tetrabothrius forsteri, Tetrabothrius sp., Trigonocotyle sp., Diphyllobothrium sp. (Cestoda), Campula sp. (Trematoda), Bolbosoma sp. (Acanthocephala), Cyamus boopis, Syncyamus pseudorcae and Xenobalanus globicipitis (Crustacea). The identification of some species represented novel records for the country and increased the occurrence of some parasites to new hosts. The use of standardized methodologies for collecting and evaluating a larger number of animals is essential for a better understanding of host-parasite relationships in cetaceans and their use as biological indicators in the region.

    Pathological processes observed in the stomatognathic systems of mammalian species are a useful source of information about the habits, evolution and general health of such animals. Studies of pathological conditions on teeth are common in humans and other primates, but rare in wild animals in general and marine mammals in particular. For cetaceans, previous studies provided scanty records of dental anomalies in a few species. This is the first broad and systematic inventory of dental pathology in dolphins. Specimens stored at scientific collections from the southern coast of Brazil were visually inspected under a stereoscopic microscope using a dental explorer. Diagnosis of lesions and anomalies followed literature descriptions. Abnormalities such as caries-like lesions, mineralized calculus deposits, dental erosion, enamel anomalies (hypoplasia and exogenous pigmentation), root resorption, germination and other shape anomalies, were diagnosed in the delphinids Sotalia guianensis, Delphinus capensis, Stenella frontalis, Stenella coeruleoalba, Lagenodelphis hosei, Pseudorca crassidens, Orcinus orca, Steno bredanensis and Tursiops truncatus. Endogenous causes may be related to the occurrence of certain conditions, but the aetiology of caries-like lesions and calculus accumulation is still unknown for cetaceans. The diagnosis of alveolar anomalies and other bone lesions in specimens with dental pathology lead us to believe these lesions modify the integrity of the periodontal ligament and bony tissues, adding to the burden of morbidity of affected animals.

    There is a possibility that the wide-band MT observation data obtained in the central part of Tohoku district include the static shift effect. To grasp the static shift effect in the MT data, the TEM soundings were conducted at all the site where the MT data were measured. The TEM sounding system was developed for the shallow survey depth ranging from 5 m to 150 m. When showing the measured results on the histogram, it was found that the static shifts were concentrated in the vicinity of zero. About 70% of the data was below 0.2 decade. Only a slight static shift effect was observed. This means that the results obtained by the two-dimensional analysis are plausible. Especially, the static shift around plain was small. Therefore, the current results around the plain were trustful. On the other hand, the static shift in the mountainous area was rather large. Accordingly, the results around the mountainous area should be carefully treated. 7 refs., 10 figs.

    We have applied a fuel behavior model to a fuel injection system which we call SOFIS (Sophisticated and Optimized Fuel Injection System) so that we get air/fuel ratio control accuracy and good driveability. However the fuel behavior under starting conditions is still not clear. To meet low emission rules and to get better driveability under starting conditions, better air/fuel ratio control is necessary. Now we have understood the ignition timing, injection timing, and injection pulse width required in such conditions. In former days, we analyzed the state of the air/fuel mixture under cold conditions and made a new fuel behavior model which considered fuel loss such as hydrocarbons and dissolution into oil and so on. Al this time, we have applied this idea to starting. We confirm this new model offers improved air/fuel ratio control. 6 refs., 9 figs., 3 tabs.

    Full Text Available The Truth and Reconciliation Commission (TRC of Canada was established to uncover and acknowledge the injustices that took place in Indian residential schools and, in doing so, to pave the way to reconciliation. However, the TRC does not define reconciliation or how we would know it when (and if we get there, thus stirring a debate about what it could mean. This article examines two theories that may potentially be relevant to the TRC’s work: Charles Taylor’s theory of recognition and Nancy Fraser’s tripartite theory of justice. The goal is to discover what each theory contributes to our understanding of the harms that Indigenous peoples suffered in residential schools, as well as in the broader colonial project, and how to address these harms appropriately.

    Full Text Available The present study was aimed to evaluate the analgesic and anti-inflammatory properties of Castanospermum australe and to profile phytochemicals by GC-MS. The ethanolic extracts were prepared by successive solvent extraction using Soxhlet apparatus. The analgesic activity was analyzed by hot plate method and acetic acid-induced writhing test whereas anti-inflammatory study was done by carrageenan induced paw oedema model. The acute toxicity study revealed that ethanol extracts of leaf and bark of C. australe were safe even at a higher dose of 2000 mg/kg whereas ethanol extract of seed was toxic at the same dose. In both hot plate method (5.85 s and acetic acid-induced writhing test (57%, the leaf ethanol extract exhibited significant analgesic activity (P<0.001 at a dose of 400 mg/kg. The anti-inflammatory activity of leaf extract was exhibited by the reduction in paw linear diameter by 64.76% at 400 mg/kg in carrageenan induced paw oedema. The GC-MS analysis of the ethanol extract of leaf revealed sixteen major compounds of which 1,7-dimethyl-4,10-dioxa-1,7-diazacyclododecane, (+-N-methylephedrine, and permethylspermine were found to be pharmaceutically and the most important. These findings justify that C. australe can be a valuable natural analgesic and anti-inflammatory source which seemed to provide potential phytotherapeutics against various ailments.

    Dryopteris blanfordii (C.Hope) C.Chr. is a member of the Dryopteridaceae, growing in high altitude Picea or Abies forests (2900-3500 m) in China and India. Phylogenetic relationships between D. blanfordii subsp. nigrosquamosa and closely related species of Dryopteris were investigated using a combined analysis of multiple molecular data sets (the protein-coding region of rbcL and matK genes and intergenic spacers psbA-trnH , trnP-petG , rps4-trnS , trnL-trnF and rbcL-accD ). An assumption about the position of D. blanfordii subsp. nigrosquamosa within Dryopteris was made by using the Maximum Likelihood and Bayesian Inference approach and chloroplast marker sequences of Dryopteris species from GenBank. The results demonstrated that Asian taxa D. blanfordii subsp. nigrosquamosa and D. laeta as well as two American species D. arguta and D. marginalis belong to the same clade, all four of them being part of Dryopteris section Dryopteris.

    The IUCN Red List of Threatened Species has categorized Malaysian primates from being data deficient to critically endanger. Thus, ancient DNA analyses hold great potential to understand phylogeny, phylogeography and population history of extinct and extant species. Museum samples are one of the alternatives to provide important sources of biological materials for a large proportion of ancient DNA studies. In this study, a total of six museum skin samples from species Presbytis hosei (4 samples) and Presbytis frontata (2 samples), aged between 43 and 124 years old were extracted to obtain the DNA. Extraction was done by using QIAGEN QIAamp DNA Investigator Kit and the ability of this kit to extract museum skin samples was tested by amplification of partial Cyt b sequence using species-specific designed primer. Two primer pairs were designed specifically for P. hosei and P. frontata, respectively. These primer pairs proved to be efficient in amplifying 200bp of the targeted species in the optimized PCR conditions. The performance of the sequences were tested to determine genetic distance of genus Presbytis in Malaysia. From the analyses, P. hosei is closely related to P. chrysomelas and P. frontata with the value of 0.095 and 0.106, respectively. Cyt b gave a clear data in determining relationships among Bornean species. Thus, with the optimized condition, museum specimens can be used for molecular systematic studies of the Malaysian primates.

    The University of the Fraser Valley has been researching the water chemistry of the Fraser River since 2009 as a member of the Global Rivers Observatory coordinated by Woods Hole Oceanographic Institution and Woods Hole Research Center. The Global Rivers Observatory is advancing our understanding of how climate change, deforestation, and other disturbances are impacting river chemistry and land-ocean linkages. This knowledge is vital for tracking the health of Earth's watersheds and predicting how Earth's water and chemical cycles will change in the future. The Global Rivers Observatory also promotes the communication of science to the general public. In September 2013, the My River My Home art and science exhibit opened at the Fraser River Discovery Centre, New Westminster, BC. The exhibit is a global exchange of artwork created by children living along the rivers being studied by the Global Rivers Observatory scientists. The exhibit is intended to inspire young students to develop an awareness of the environment and the importance of rivers. Scientists from UFV, WHOI, and WHRC worked together with the Fraser River Discovery Centre on the science communication aspects of the display and to develop hands-on science activities looking at different aspects of river water quality. The exhibition has led to the creation of My River My Home, An Activity Kit for Educators about the sustainability of the Fraser River. The kit is being offered through the Fraser River Discovery Centre and deals with issues such as the importance of water, water quality, and encouraging a global perspective. The resource kit was classroom tested by several teachers, and four UBC teacher candidates worked on incorporating teacher suggestions into the kit. The resource kit will be available on-line at the end of September 2014 and contains inquiry based activities suitable for a variety of educational levels.

  20. The Physical Oceanography of Australia's Sunshine Coast

    Science.gov (United States)

    Ribbe, Joachim

    2017-04-01

    Australia's Sunshine coast is located to the south of the Great Barrier Reef and Fraser Island between about 25 oS to 28 oS. With a width of nearly 70-80 km, the eastern Australian continental shelf is at its widest here. The shelf region is referred to as the Southeast Queensland Marine Coastal Zone due to its unique physical oceanographic characteristics. The most prominent large-scale oceanic feature is the southward flowing East Australian Current (EAC). It forms to the north of Fraser Island from Coral Sea outflows, intensifies, and follows the continental shelf as a swift continental shelf hugging current but variable in strength; stronger in the southern hemisphere summer and weaker in winter. Little attention has been paid to the physical oceanography of this region, although important physical processes take place that drive regional marine environmental conditions, drive cross-shelf exchanges and interactions with the EAC, and that represent marine connectivity processes significant to the larger scale eastern Australian fisheries. This presentation reviews recent discoveries that include the Southeast Fraser Island Upwelling System, the Fraser Island Gyre, and document the role of cyclonic mesoscale eddies in driving cross-shelf exchanges and contribute to the formation of the Fraser Island Gyre. The Southeast Fraser Island Upwelling System appears to be predominately driven by the interaction of the EAC with the continental shelf leading to the establishment of one of eight important marine ecological hotspots along the east Australian coast. The Fraser Island Gyre is most prominent during the southern hemisphere autumn and winter months. It is characterised by on-shelf northerly flow, turning eastward south of Fraser Island before joining the EAC. It emerges that cyclonic eddy formation as well as the south-easterly trade winds drive the gyre's establishment and strength. A census of short-lived (7-28 days) cyclonic eddies, the first for any western

    The aim of this study was to optimize a Real-Time PCR protocol for a rapid detection of Listeria monocytogenes in pork meat, using reduced volumes of primary selective enrichment broth and times of incubation to decrease the cost and time for analysis. Forty-five samples of pork meat were artificially contaminated with two different levels of L. monocytogenes (1-10 CFU per sample and 10-100 CFU per sample), homogenized in three different volumes of Half Fraser Broth (1:3; 1:5 and 1:10) and incubated at 30°C ± 1°C for 5h, 8h and 24h. The detection was conducted in parallel by Real-Time PCR and the ISO standard 11290-1 methods. L. monocytogenes was detected in all the samples after 24h by Real-Time PCR method, also using reduced volumes of Half Fraser Broth. This represents a clear advantage as the time to final detection and the inherent costs were significantly reduced compared to the ISO reference method. All samples artificially contaminated were correctly detected also after 8 of incubation at 30°C ± 1°C in Half Fraser Broth and 24h in Fraser Broth at 37°C ± 1°C using cultural method.

    This dissertation centers on the application of the mental space theory to expand our understanding of the role lexical discourse markers (LDMs) play in discourse. LDMs have been recognized by many researchers for their discourse connective function(s) (Levinson, 1983; Schiffrin, 1987; Blakemore, 1989, 2000, 2001, 2002; Fraser, 1996, 1999, 2006).…

  16. Species tree of a recent radiation: the subfamily Delphininae (Cetacea, Mammalia).

    Science.gov (United States)

    Amaral, Ana R; Jackson, Jennifer A; Möller, Luciana M; Beheregaray, Luciano B; Manuela Coelho, M

    2012-07-01

    Lineages undergoing rapid radiations provide exceptional opportunities for studying speciation and adaptation, but also represent a challenge for molecular systematics because retention of ancestral polymorphisms and the occurrence of hybridization can obscure relationships among lineages. Dolphins in the subfamily Delphininae are one such case. Non-monophyly, rapid speciation events, and discordance between morphological and molecular characters have made the inference of phylogenetic relationships within this subfamily very difficult. Here we approach this problem by applying multiple methods intended to estimate species trees using a multi-gene dataset for the Delphininae (Sousa, Sotalia, Stenella, Tursiops, Delphinus and Lagenodelphis). Incongruent gene trees obtained indicate that incomplete lineage sorting and possibly hybridization are confounding the inference of species history in this group. Nonetheless, using coalescent-based methods, we have been able to extract an underlying species-tree signal from divergent histories of independent genes. This is the first time a molecular study provides support for such relationships. This study further illustrates how methods of species-tree inference can be very sensitive both to the characteristics of the dataset and the evolutionary processes affecting the evolution of the group under study.

    Greven, H; Laumeier, I

    1987-01-01

    Teeth of 10 anuran species have been investigated by means of scanning electron microscopy (SEM). Generally a great variability of the structure of dentine crowns and the zone of division was noted not only between the single species, but also within one species on the same dentigerous bone. 4 species (Hyla cinerea, Rana ridibunda, R. hosei, Ptychadena spec.) mostly have more or less bladed bicuspid and clearly divided teeth corresponding to the "Lissamphibia"-pattern. 2 species (Xenopus laevis, X. spec.) exhibit conical spike-like teeth with a trace of a dividing zone similar to those observed in late stage larvae of Urodela. One species (Ceratophrys cranwelli) shows undivided bladed monocuspid teeth. It is assumed that the 2 species of Dendrobatidae (Dendrobates tricolor, D. anthonyi) examined have no zone of division. Its occurrence in Gastrotheca riobambae and in the few juvenile D. tricolor available is still doubtful. Results are discussed regarding the variability of tooth structures (dentine crown, zone of division, pedicel) and the occurrence of 2 types of monocuspid teeth in the Amphibia as well as its possible bearing upon phylogeny and systematics of this group.

  19. MODERNISATION ISSUES OF GENDER AND SPACE

    Directory of Open Access Journals (Sweden)

    Titien Saraswati

    2000-01-01

    Full Text Available Jurgen Habermas proposes a theory of modernisation based on the notion of a progressive "uncoupling" or separation of some aspects of everyday life, and their take over or "colonisation" by an expanding state and formal economy. This model is criticised by Nancy Fraser on the basis that it ignores the place of gender in the various roles that the individual plays in society and which mediate between the world of everyday life and the "system world" of the state and the official economy. Habermas's argument is further criticised for ignoring the issue of space (the house, the neighbourhood in that mediation. Further, Habermas and also Fraser arguments however yield to what they call symbolic reproduction and material reproduction, socially integrated action contexts and system integrated action contexts, and also private sphere and public sphere. The above terms will be elaborated more fully in this paper.

    Pess, G. R.; Hilborn, R.; Kloehn, K.; Quinn, T.

    2010-12-01

    The transition from dispersal into unoccupied habitat to the establishment of a self-sustaining new population depends on the dynamics of the source and recipient populations, and the environmental conditions that facilitate or hinder exchange and successful reproduction. We used population growth rate, inter-annual variability estimates, habitat condition and size, hydrologic data, and an estimated dispersal effect to determine when colonizing pink salmon (Oncorhynchus gorbuscha) populations became self-sustaining after a long-term migration blockage (Hell’s Gate) was mitigated in the Fraser River, British Columbia, Canada. We used pink salmon spawning data from 1947 to 1987 in 66 streams to define populations, population growth rates, and the level of dispersal to newly accessible habitats. We also quantified the distance from source populations, the amount of newly accessible habitat, and determined whether stream flow conditions impeded fish passage at Hell’s Gate. Population dynamics models fit to observed data indicated that the combination of an initially large source population in the Fraser River below Hell’s Gate, high intrinsic growth rates linked to favorable climate-driven conditions, a constant supply of dispersers, and large amounts of newly available habitat resulted in the development of self-sustaining pink salmon populations in the Fraser River upstream of the historic barrier. Self-sustaining populations were developed within years of barrier removal and have continued to help expand the overall population of Fraser River pink salmon. However, not all locations had the same productivity and the magnitude of exchange among them was partly mediated by river conditions that permit or impede passage. Both re-colonized abundance levels were reduced and population spatial structure shifted relative to historic population abundance and spatial structure estimates.

    Faculty and students from the University of the Fraser Valley (UFV) have conducted time series sampling of the Fraser River at Fort Langley and six Fraser Valley tributaries as a member of the Global Rivers Observatory (GRO, www.globalrivers.org) coordinated by Woods Hole Oceanographic Institution and Woods Hole Research Center. The Clayburn - Willband - Stoney watershed has become a focus of the sampling being conducted by faculty and students from the Geography and Biology Departments at UFV. Water chemistry data (water temperature, dissolved oxygen, conductivity, pH and turbidity) and samples (nutrients, major ions and bacteria) have been collected weekly from sites on these creeks. These watersheds are threatened by increasing urban development, increasing idustrial activity, and expansion of agricultural landuse within the watershed. Documenting the seasonal changes in the water chemistry as measured during the onset of the heavy fall and winter precipitation events, the wet and cool winters and springs, and the hot and dry summers will assist in attempts to protect these important salmon spawning streams from anthropogenic activity.

    Several streams in the Abbotsford region of the Fraser Valley, B.C., Canada, have been used as long term study sites for our ecology and geography courses. In collaboration with Woods Hole Oceanographic Institution we have been collecting water quality data from the Fraser River as part of the Global Rivers Observatory since 2009. The small stream sites are used for monitoring stream and river chemistry, physical characteristics, riparian influences, and using leaf litter bags to study decomposition rates and the macro-invertebrate community. In the introductory ecology course and the upper level independent freshwater ecology course, students conduct increasingly sophisticated experiments, such as: comparative stream chemistry and biological studies in one to several streams. These courses ladder into each other, students gain skills in the field and lab in their introductory course, such as preparing leaf litter bags, measuring dissolved phosphate and nitrate, and identifying invertebrates. In the introductory ecology course students begin applying statistics to their data and are encouraged to formulate their own hypothesis, and this is expanded upon in the upper level stream ecology course. In the upper level course, two to six students work as a team to conduct the field and laboratory studies, each student develops his/her own hypothesis and prepares a research report and poster. Students can analyze data collected for as long as 10 years from six different streams and the Fraser River. By investigating data from several years students are now able to observe trends.

    A review of the taxonomic status of the Asian Slug Snake, Asthenodipsas vertebralis (Boulenger, 1900) based on an integrative taxonomic approach using molecular, morphological, color pattern, and ecological data indicate it is composed of three well supported monophyletic lineages: (1) Pulau Tioman and Fraser's Hill, Pahang and Bukit Larut, Perak; Peninsular Malaysia; (2) its sister lineage from Northern Sumatra; and (3) the remaining basal lineage from Peninsular Malaysia. Furthermore, we consider the high sequence divergence (6.3%-10.2%) between these lineages (especially in areas of sympatry) and discrete differences in their morphology, color pattern, and microhabitat preference as evidence they are not conspecific. As such, we resurrect the name A. tropidonotus (Lidth de Jeude, 1923) for the Sumatra populations, restrict the name A. vertebralis to the populations from Pulau Tioman, Genting Highlands, Fraser's Hill, Gunung Benom, and Bukit Larut that contain terrestrial, banded adults; and consider A. lasgalenensis sp. nov. to be restricted to the populations from Fraser's Hill, Cameron Highlands, and Bukit Larut that contain arboreal, unbanded adults.

  18. The 1989 Ms 7.1 Loma Prieta, California, Magnetic Earthquake Precursor Revisited

    2007-12-01

    Repeatable prediction of individual large earthquakes on the basis of quantitative geophysical data has proven to be frustratingly difficult and fraught with controversy. Still, some claims of success have been published, and among these are reports of identifiable precursory changes in magnetic-field activity as measured by ground- based magnetometers. By far the most prominent of such claims is that of Fraser-Smith et al., GRL, 17, 1465- 1468, 1990 who identified changes in Ultra Low Frequency (ULF, 0.01-10 Hz) magnetic noise prior to the 18 October 1989 Ms 7.1 Loma Prieta, California earthquake. The Fraser-Smith et al. result has been frequently cited in the literature, and it has been a major motivational influence for new research programs involving large arrays of ground-based instruments and even some satellite-based systems. We re-examine the data of the reported precursor, comparing them against independent data collected by magnetometers located in Japan and in the United States at the time of the Loma Prieta earthquake. From our analysis we infer that the key components of the precursory signal identified by Fraser-Smith et al. can be explained by minor corruption of the data in the form of a gain enhancement and time-stamp missassignment, possibly due to digital processing errors or inadvertent post-acquisitional treatment. We conclude that the reported magnetic anomaly is not related to the Loma Prieta earthquake.

    Full Text Available The rate of reforestation  has increased throughout the countries in Southeast Asia region during the last 20 years.  At the same time, inconvenient situations such as forest destruction, forest exploitation, illegal logging, clear-cut forest areas, old agricultural lands, post-wildfire areas, conversion  of natural  forests into  plantations, resettlement areas, mine  lands,  and amended adverse soils have also been increasing  significantly. Mycorrhizas, hovewer,  play important role  to increase  plant  growth,  enrich  nutrient content  and enhance  survival rates of forest tree species in temperate  and sub-tropical  regions.  Unfortunately, a little information so far is available  regarding  the effect of mycorrhizas on growth  of tree species growing  in tropical  forests. In relevant,  several experiments  were carried  out to determine whether  ectomycorrhizal (ECM fungi and arbuscular  mycorrhizal (AM fungi can enhance mycorrhizal colonization, nutrient content, and plant growth of some tropical rain forest tree species in Indonesia under nursery  and field conditions.   The families of tropical  tree species used in the experiment were  Thymelaeaceae (Aquilaria crassna, Leguminosae  (Sesbania grandifolia, Guttiferae (Ploiarium alternifolium and Calophyllum hosei, Apocynaceae (Dyera polyphylla and Alstonia scholaris, and Dipterocarpaceae (Shorea belangeran. These families are important as they provide timber  and non-timber  forest products (NTFPs.   This paper discusses the role of mycorrhizal fungi in increasing  early  growth  of tropical  tree seedlings in adverse soil.

  20. Surgical travellers: tapestry to Bayeux.

    Hedley-Whyte, John; Milamed, Debra R

    2014-09-01

    The planning for surgery in war was revisited in 1937 when Ian Fraser was elected a member of the Surgical Travellers. At their 1938 Surgical Travellers meeting in Vienna, Ian and Eleanor Fraser were evicted from their hotel room by the Nazis. The 1939 meeting in Belfast discussed the organization of surgery and the conduct of Emergency Medical Service Hospitals in the United Kingdom; the vast majority were to be under civilian government and military control. From 1943 lengthy and informative organizational meetings were held at least monthly under the chairmanship of Sir Alexander Hood, KBE, Head of the RAMC. Surgical Consultants, now Major Generals, Brigadiers or Full Colonels in the British and U.S. Armies stationed in the UK, prepared for the invasion of Europe. The allocation of medical, surgical, nursing and auxiliary responsibilities was delineated. Liaison with the RAF and US Army Air Force was close as it was with the proposed leaders, Ulstermen Brooke and Montgomery. Montgomery chose Arthur Porritt as Surgeon in Chief to Supreme Headquarters Allied Expeditionary Force (SHAEF), and Eisenhower, General Albert W. Kenner. Just after D-Day, Porritt met Ian Fraser, who had waded in on Arromanches Beach. The triage and evacuation plans for Allied casualties had been controversial, particularly as regards Landing Ship Tanks (LSTs). The dispute with the Hood-selected surgeons on one side, against medical and surgical deployment of LSTs, and Admiral Ernest King and Winston Churchill on the other, favouring LST use for surgery and evacuation. King and Churchill were correct but total Allied air superiority allowed wide use of many of the Allies' Dakotas; 10,000 DC-3s were eventually in service. Supported by forty Allied combat planes to each Luftwaffe, the dispute about Landing Ship Tank use in about a fortnight became moot.

    Climate change is commonly evaluated as the difference between simulated climates under future and current forcings, based on the assumption that systematic errors in the current-climate simulation do not affect the climate-change signal. In this paper, we investigate the Canadian Regional Climate Model (CRCM) projected climate changes in the climatological means and extremes of selected basin-scale surface fields and its sensitivity to model errors for Fraser, Mackenzie, Yukon, Nelson, Churchill and Mississippi basins, covering the major climate regions in North America, using current (1961-1990) and future climate simulations (2041-2070; A2 and IS92a scenarios) performed with two versions of CRCM.Assessment of errors in both model versions suggests the presence of nonnegligible biases in the surface fields, due primarily to the internal dynamics and physics of the regional model and to the errors in the driving data at the boundaries. In general, results demonstrate that, in spite of the errors in the two model versions, the simulated climate-change signals associated with the long-term monthly climatology of various surface water balance components (such as precipitation, evaporation, snow water equivalent (SWE), runoff and soil moisture) are consistent in sign, but differ in magnitude. The same is found for projected changes to the low-flow characteristics (frequency, timing and return levels) studied here. High-flow characteristics, particularly the seasonal distribution and return levels, appear to be more sensitive to the model version.CRCM climate-change projections indicate an increase in the average annual precipitation for all basins except Mississippi, while annual runoff increases in Fraser, Mackenzie and Yukon basins. A decrease in runoff is projected for Mississippi. A significant decrease in snow cover is projected for all basins, with maximum decrease in Fraser. Significant changes are also noted in the frequency, timing and return levels for low

  2. Liming of acidified waters: issues and research - a report of the International Liming Workshop

    Schreiber, R. Kent

    1982-01-01

    Acidic deposition is a problem of significant national and international concern. It is strongly suspected that acidic deposition has adversely affected aquatic resources in Scandinavia and North America. While substantial resources are being devoted to understanding the causative factors associated with surface water acidification, much less research is being conducted on mitigative strategies. Mitigative techniques involving liming may be useful for short-term protection of specific component of aquatic communities or for renovation of seriously impacted aquatic ecosystems. The selection of effective liming strategies is based on an integrated understanding of the following key factors: biological systems, water chemistry, sediment chemistry, hydrology, and watershed characteristics, effectiveness of neutralizing materials, and application techniques. Research in Scandinavia, Canada, and the U.S. has led to a partial understanding of some of the key factors for successful neutralization of surface waters (Bengtsson, 1982; Fraser and Britt, 1982). However, conflicting results of liming operations and experiments have been reported. (Fraser et al., 1982; Fraser and Britt, 1982; Sverdrup and Bjerle, 1982). Additional research is required to improve the ability of scientists and resource managers to select effective liming strategies. An International Liming workshop was convened during 19-25 September 1982 at the University of Washington's Friday Harbor Laboratories. The major objective of this workshop were: - To identify the most critical deficiencies in the scientific understanding of liming techniques and their long-term consequences. - To develop and document a research strategy to address information deficiencies that are pertinent to the protection or renovation of acidic surface waters in the United States. The participants who contributed to this workshop are listed in Table 1.

  3. Winter body mass and over-ocean flocking as components of danger management by Pacific dunlins.

    We compared records of the body mass and roosting behavior of Pacific dunlins (Calidris alpina pacifica) wintering on the Fraser River estuary in southwest British Columbia between the 1970s and the 1990s. 'Over-ocean flocking' is a relatively safe but energetically-expensive alternative to roosting during the high tide period. Fat stores offer protection against starvation, but are a liability in escape performance, and increase flight costs. Peregrine falcons (Falco peregrinus) were scarce on the Fraser River estuary in the 1970s, but their numbers have since recovered, and they prey heavily on dunlins. The increase has altered the balance between predation and starvation risks for dunlins, and thus how dunlins regulate roosting behavior and body mass to manage the danger. We therefore predicted an increase in the frequency of over-ocean flocking as well as a decrease in the amount of fat carried by dunlins over these decades. Historical observations indicate that over-ocean flocking of dunlins was rare prior to the mid-1990s and became common thereafter. Residual body masses of dunlins were higher in the 1970s, with the greatest difference between the decades coinciding with peak peregrine abundance in October, and shrinking over the course of winter as falcon seasonal abundance declines. Whole-body fat content of dunlins was lower in the 1990s, and accounted for most of the change in body mass. Pacific dunlins appear to manage danger in a complex manner that involves adjustments both in fat reserves and roosting behavior. We discuss reasons why over-ocean flocking has apparently become more common on the Fraser estuary than at other dunlin wintering sites.

    The ancestral waters of the Coast Salish People, the Salish Sea, comprise a large inland sea contained within both United States (Puget Sound) and Canadian (Georgia Strait) territory. The Salish Sea is home to more than 220 species of fish, 29 species of marine mammals, more than 40 species of commercial and recreationally harvested invertebrates, and numerous resident and migratory bird species (Washington Sea Grant Program, 2000). Unfortunately, at least 60 of these marine based species are listed as threatened, endangered or of concern (Fraser and others, 2006), many of which sustained Coast Salish for millennia and are of essential cultural importance.

  15. MODERNISATION ISSUES OF GENDER AND SPACE

    OpenAIRE

    Titien Saraswati

    2000-01-01

    Jurgen Habermas proposes a theory of modernisation based on the notion of a progressive "uncoupling" or separation of some aspects of everyday life, and their take over or "colonisation" by an expanding state and formal economy. This model is criticised by Nancy Fraser on the basis that it ignores the place of gender in the various roles that the individual plays in society and which mediate between the world of everyday life and the "system world" of the state and the official economy.

  16. Literary Samizdat and Samizdat Publics

    Directory of Open Access Journals (Sweden)

    Ann Komaromi

    2015-07-01

    Full Text Available In this article Komaromi considers literary samizdat journals in light of public theory. Although literary samizdat journals do not conform to classic conceptions of public speech, they do yield to more recent analyses of counter-publics proposed by Nancy Fraser and Michael Warner. Picking up on the poetic aspects of public speech highlighted by Warner, Komaromi examines the publics projected by literary samizdat journals through statements about those publics, style, and bibliographic values. While not directly contesting political conditions, these literary journals amplified the implications of samizdat production and distribution to foster plurality and human connection as a basis for a better future.

  19. Beyond ambivalence: the new challenge of feminism

    Directory of Open Access Journals (Sweden)

    Nancy Fraser

    2016-07-01

    Full Text Available This essay, translated here in Italian and preceded by the Author's inedited preface, reconstructs the trajectory of second wave feminism since the 60s, exploring its ambivalences. Shifting from an analysis focused on economic redistribution to one founded on recognition of differences, feminism has sacrificed the critique of neoliberalism on the altar of women's emancipation. In order to break the tie with neoliberalism, Fraser proposes a new conception of social justice that links the principle of non-domination with those of social protection and solidarity.

  1. Natural magnetic disturbance fields, not precursors, preceding the Loma Prieta earthquake

    Science.gov (United States)

    Campbell, Wallace H.

    2009-05-01

    Available records of the magnetic indices Dst and ap together with standard observatory recordings of 1-min field levels were examined for the period preceding the earthquake of October 1989, centered near Loma Prieta, California. The magnetic records showed that the Fraser-Smith et al. (1990) report claiming the existence of a 100-s (ultralow frequency) geomagnetic field precursor signal at Corralitos, California, foretelling a nearby earthquake is not valid. My study shows that the Stanford ULF signal was not local but rather widespread throughout the western United States and, therefore, expected to be due to a coincidental geomagnetic solar-terrestrial disturbance field.

  2. HIV treatment as prevention: debate and commentary--will early infection compromise treatment-as-prevention strategies?

    Directory of Open Access Journals (Sweden)

    Myron S Cohen

    Full Text Available Universal HIV testing and immediate antiretroviral therapy for infected individuals has been proposed as a way of reducing the transmission of HIV and thereby bringing the HIV epidemic under control. It is unclear whether transmission during early HIV infection--before individuals are likely to have been diagnosed with HIV and started on antiretroviral therapy--will compromise the effectiveness of treatment as prevention. This article presents two opposing viewpoints by Powers, Miller, and Cohen, and Williams and Dye, followed by a commentary by Fraser.

    Cox, Stephen E.; Kahle, Sue C.

    1999-01-01

    Ground water is an important source of domestic, municipal, and irrigation water supply throughout the Fraser-Whatcom Lowland, particularly for the 225-square mile agricultural area surrounding the Whatcom County communities of Lynden, Everson, Nooksack, and Sumas and the British Columbia communities of Abbotsford and Aldergrove. Population growth and developing ground-water-quality problems have increased the demand for additional sources of ground water. The U.S. Geological Survey, in cooperation with the Whatcom County Planning Department, collected water-level, lithologic, and water-quality data from 608 wells during 1990-92 to complete a regional appraisal of the ground-water system.

    Detailed dose rate maps for a neutron generator facility at Simon Fraser University were produced via the GEANT4 Monte Carlo framework. Predicted neutron dose rates throughout the facility were compared with radiation survey measurements made during the facility commissioning process. When accounting for thermal neutrons, the prediction and measurement agree within a factor of 2 or better in most survey locations, and within 10 % inside the vault housing the neutron generator. © The Author 2015.

  15. Epidemiology as a liberal art: from graduate school to middle school, an unfulfilled agenda.

    Bracken, Michael B

    2014-03-01

    Calls by Lilienfeld, Fraser, and others some three decades ago to introduce epidemiology into undergraduate college education remain largely unfulfilled. Consideration of epidemiology as a "liberal art" has also led to exploring possibilities for introducing epidemiology into early education: to high and even middle schools. Adding epidemiology to school curricula should help educate the public to understand science-based evidence concerning the causes and treatments of disease, help inoculate them against a tsunami of biased and fraudulent media messaging, and permit advancing postgraduate education in epidemiology to even higher levels of scholarship.

  1. The implementation of multi-task geophysical survey to locate Cleopatra Tomb at Tap-Osiris Magna, Borg El-Arab, Alexandria, Egypt “Phase II”

    Directory of Open Access Journals (Sweden)

    Abbas M. Abbas

    2012-06-01

    VLF-EM data were collected along parallel lines covering the investigated site with a line-to-line spacing of 1 m. The point-to-point distance of 1 m along the same line was employed. The data were qualitatively interpreted by Fraser filtering process and quantitatively by 2-D VLF inversion of tipper data and forward modeling. Results obtained from VLF-EM interpretation are correlated with 2-D resistivity imaging and drilling information. Findings showed a highly resistive zone at a depth extended from about 25–45 m buried beneath Osiris temple, which could be indicated as the tomb of Cleopatra and Anthony. This result is supported by Fraser filtering and forward modeling results. The depth of archeological findings as indicated from the geophysical survey is correlated well with the depth expected by archeologists, as well as, the depth of discovered tombs outside Tap-Osiris Magna temple. This depth level has not been reached by drilling in this site. We hope that the site can be excavated in the future based on these geophysical results.

  2. A Genealogy of (post-Soviet Dependency: Disabling Productivity

    Directory of Open Access Journals (Sweden)

    Cassandra Hartblay

    2014-02-01

    Full Text Available Nancy Fraser and Linda Gordon's 1994 article “A Genealogy of Dependency: Tracing a Keyword of the US Welfare State” explored the historical emergence of "dependency" as a moral category of post-industrial American state. In this article, I engage their framework to explore the genealogy of dependency in America's post-industrial sister, the post-Soviet Russian Federation. I also add disability as a core element of 'dependency' that was largely absent from Fraser and Gordon's original analysis. Considering cross-cultural translation, I ask how Russian deployments of three words that all relate to a concept of interdependence align with and depart from American notions of dependency, and trace historical configurations of the Soviet welfare state vis-a-vis disability. To do so, I draw on historical and cultural texts, linguistic comparisons, secondary sources, and ethnographic research. Given this analysis, I argue that rather than a Cold War interpretation of the Soviet Union and the US as oppositional superpowers in the 20th century, a liberatory disability studies framework suggests that in the postindustrial era the Soviet Union and the United States emerged as dual regimes of productivity. I suggest that reframing postsocialism as a global condition helps us to shift considerations of disability justice from a critique of capitalism to a critique of productivity.    Keywords: dependency, disability, citizenship, russia, productivity

    2018-03-01

    Snowmobile use is a popular form of winter recreation in Colorado, particularly on public lands. To examine the effects of differing levels of use on snowpack properties, experiments were performed at two different areas, Rabbit Ears Pass near Steamboat Springs and at Fraser Experimental Forest near Fraser, Colorado USA. Differences between no use and varying degrees of snowmobile use (low, medium and high) on shallow (the operational standard of 30 cm) and deeper snowpacks (120 cm) were quantified and statistically assessed using measurements of snow density, temperature, stratigraphy, hardness, and ram resistance from snow pit profiles. A simple model was explored that estimated snow density changes from snowmobile use based on experimental results. Snowpack property changes were more pronounced for thinner snow accumulations. When snowmobile use started in deeper snow conditions, there was less difference in density, hardness, and ram resistance compared to the control case of no snowmobile use. These results have implications for the management of snowmobile use in times and places of shallower snow conditions where underlying natural resources could be affected by denser and harder snowpacks.

  6. Measuring Economic Freedom: Better Without Size of Government.

    Science.gov (United States)

    Ott, Jan

    2018-01-01

    The Heritage Foundation and the Fraser Institute measure economic freedom in nations using indices with ten and five indicators respectively. Eight of the Heritage indicators and four of the Fraser-indicators are about specific types of institutional quality, like rule of law, the protection of property, and the provision of sound money. More of these is considered to denote more economic freedom. Both indices also involve indicators of 'big government', or levels of government activities. More of that is seen to denote less economic freedom. Yet, levels of government spending, consumption, and transfers and subsidies appear to correlate positively with the other indicators related to institutional quality, while this correlation is close to zero for the level of taxation as a percentage of GDP. Using government spending, consumption transfers and subsidies as positive indicators is no alternative, because these levels stand for very different government activities, liberal or less liberal. This means that levels of government activities can better be left out as negative or positive indicators. Thus shortened variants of the indices create a better convergent validity in the measurement of economic freedom, and create higher correlations between economic freedom and alternative types of freedom, and between economic freedom and happiness. The higher correlations indicate a better predictive validity, since they are predictable in view of the findings of previous research and theoretical considerations about the relations between types of freedom, and between freedom and happiness.

    Listeria monocytogenes is a human pathogen causing serious diseases. We aimed to determine food contamination with Listeria spp. in Kermanshah, Islamic Republic of Iran. Samples (185 dairy, 187 meat products and 158 ready-to-eat foods such as salads) were randomly collected from markets. After processing, samples were cultured in half-Fraser and Fraser broth followed by cultivation on PALCAM and Oxford media. Confirmatory tests including carbohydrate utilization were performed on isolates to determine species. Bacteria were isolated from 66/530 samples (12.5%). Meat products showed the highest (27.2%) and dairy products the lowest (3.8%) contamination rates. L. innocua was found in 56 (10.6%) samples, but L. monocytogenes was only found in 3 samples (0.6%). The results indicate that the rate of contamination with L. monocytogenes, even for ready-to-eat foods, was low but for other Listeria spp., in particular strains of L. innocua, the rate of contamination was higher, suggesting that more control on food sanitation is required.

  8. River networks dampen long-term hydrological signals of climate change

    2017-07-01

    River networks may dampen local hydrologic signals of climate change through the aggregation of upstream climate portfolio assets. Here we examine this hypothesis using flow and climate trend estimates (1970-2007) at 55 hydrometric gauge stations and across their contributing watersheds' within the Fraser River basin in British Columbia, Canada. Using a null hypothesis framework, we compared our observed attenuation of river flow trends as a function of increasing area and climate trend diversity, with null-simulated estimates to gauge the likelihood and strength of our observations. We found the Fraser River reduced variability in downstream long-term discharge by >91%, with >3.1 times the attenuation than would be expected under null simulation. Although the strength of dampening varied seasonally, our findings indicate that large free-flowing rivers offer a powerful and largely unappreciated process of climate change mitigation. River networks that integrate a diverse climate portfolio can dampen local extremes and offer climate change relief to riverine biota.

    Detailed analysis of (131)I levels in rainwater and in three species of seaweed (Fucus distichus Linnaeus, Macrocystis pyrifera, and Pyropia fallax) collected in southwest British Columbia and Bella Bella, B.C., Canada was performed using gamma-ray spectroscopy following the Fukushima nuclear power plant accident on March 11, 2011. Maximum (131)I activity was found to be 5.8(7) Bq/L in rainwater collected at the campus of Simon Fraser University in Burnaby, B.C. nine days after the accident. Concomitantly, maximum observed activity in the brown seaweed F. distichus Linnaeus was observed to be 130(7) Bq/kg dry weight in samples collected in North Vancouver 11 days following the accident and 67(6) Bq/kg dry weight in samples collected from the Bamfield Marine Sciences Centre on Vancouver Island 17 days following the accident. The (131)I activity in seaweed samples collected in southwest B.C. following the Fukushima accident was an order of magnitude less than what was observed following Chernobyl. Iodine-131 activity in F. distichus Linnaeus remained detectable for 60 days following the accident and was detectable in each seaweed species collected. The Germanium Detector for Elemental Analysis and Radioactivity Studies (GEARS) was modeled using the Geant4 software package and developed as an analytical tool by the Nuclear Science group in the Simon Fraser University Department of Chemistry for the purpose of these measurements.

    Establishing the relationship between source (bedrock, soil, floodplain sediments, vegetation) and mobilized materials (bedload and suspended load) within a river drainage network is critical to understanding the fate of particulate matter exported to the coastal ocean. First, linking material carried in river channels to its terrestrial sources aides in predicting the reactivity of organic matter associated with mineral particles and understanding which portions of a watershed contribute substantially to organic carbon fluxes and transformations in these systems. Second, identifying terrestrial reservoirs of future riverine suspended material can enhance our ability to comprehensively characterize the chemical and physical nature of fluvial sediments. We present a study of sedimentological and bulk organic carbon properties of sediments from across the Fraser River watershed in southwestern British Columbia, Canada. Bulk samples and size fractions from surface soils and riverbank sediments, as well as vegetation, are analyzed for metrics including carbon and nitrogen content, 13C and 14C composition, and specific surface area. These are compared with measurements of riverine suspended sediments and size fractions of sediments deposited in the Fraser estuary. The correspondence of suspended sediment properties with different portions of soil, alluvial, and vegetation pools from different sites suggests a complex link between source materials and exported material. Such variability may stem from the heterogeneous nature of soil types, hillslope morphology, and runoff regimes in different portions of the drainage basin; settling/resuspension processes during river transit; and/or modification of particle structure and organic matter between mobilization of terrestrial material and arrival at distant downstream sites. The preferential loss/preservation of different size fractions within mineral source materials highlights the unequal importance of different mineral

    Full Text Available This paper analyzes the ProJovem discourse from its political-pedagogical project. Its goal is to develop youth involvement through education, orientation to the employment orientation and development of community actions. From the standpoint of theoretical and methodological work this study is located, in the wake of recent social theory, in the developments of the social recognition category, whose use is associated to the postcritical theory by Charles Taylor, Nancy Fraser, and Axel Honneth. This approach allows the configuration of a useful tool in understanding the discursive formation of public policy, particularly ProJovem, whose goal highlights on the one hand, symbolic recognition by emphasizing the role of youth and the equal participation of the community, and on the other hand, in recognition distributive, through education and work initiation.

    A sequence of field studies to evaluate causes of decreasing radial growth rates of red spruce at high elevations in the Great Smokey Mountains during the past 30 years has examined climatic signals, competition, xylem wood chemistry, soil chemistry, foliar nutrition and carbon allocation patterns. The resultant hypothesis that acid deposition alters red spruce growth through limiting calcium availability, and consequently net carbon assimilation, has now been tested in controlled greenhouse and field studies. Recent measurements of reduce respiration and increased photosynthesis of red spruce samplings in response to adding calcium in the field, provides additional evidence linking acid deposition to altered nutrition, physiology, and growth of red spruce. Initial data from physiological gradient analysis also support the occurrence of parallel elevational gradients in physiology of fraser fir.

    Floating knee injury has been considered as one of the severe orthopedic injury, and is often associated with major systemic trauma involving other organs. To identify the incidence of floating knee injury, severity of injury and associated orthopaedic and non-orthopaedic injury. Epidemiologic study conducted from 1 Jan 2014 to 31 Dec 2014. A total of 136 cases with floating knee injury were registered. Modified Fraser classification showed 58 patients had type 1, 74 had type 2 and 4 had type 3 floating knees. 119(87.5%) patients had open fractures and Gustilo-Anderson type IIIA(29.4%) being the commonest. No Mortality was found. 16 (11.76%) of floating knees had to undergo amputation of afflicted limb. Statics of such data would be helpful in planning and preparing ourselves as healthcare professionals to prevent high mortality and morbidity/disability in floating knee injury.

  1. Mixed deterministic statistical modelling of regional ozone air pollution

    KAUST Repository

    Kalenderski, Stoitchko

    2011-03-17

    We develop a physically motivated statistical model for regional ozone air pollution by separating the ground-level pollutant concentration field into three components, namely: transport, local production and large-scale mean trend mostly dominated by emission rates. The model is novel in the field of environmental spatial statistics in that it is a combined deterministic-statistical model, which gives a new perspective to the modelling of air pollution. The model is presented in a Bayesian hierarchical formalism, and explicitly accounts for advection of pollutants, using the advection equation. We apply the model to a specific case of regional ozone pollution-the Lower Fraser valley of British Columbia, Canada. As a predictive tool, we demonstrate that the model vastly outperforms existing, simpler modelling approaches. Our study highlights the importance of simultaneously considering different aspects of an air pollution problem as well as taking into account the physical bases that govern the processes of interest. © 2011 John Wiley & Sons, Ltd..

This paper presents the realization of an urban intervention, "Sorocabana 2014," as an example of application in enactive perspective of Soundscape creation. We show the context of Soundscapes as used to apply the knowledge derived from studies in perception, through its roots in eletroacoustic music, and the way of canadian composers of Simon Fraser University comprehend and use it. Later stages of implementing "Sorocabana 2014", while results of enactives ideas applied to the composition of Soundscapes were described. Finally we made a brief discussion on the proposal to subsidize artistic production with the enactive approach to perception. And as a conclusion it is stressed some other possibilities of aesthetic creation involving such philosophical-scientific scope.

  8. Advance, Retreat, and Halt of Abrupt Gravel-Sand Transitions in Alluvial Rivers

    Blom, Astrid; Chavarrías, Víctor; Ferguson, Robert I.; Viparelli, Enrica

    2017-10-01

    Downstream fining of bed sediment in alluvial rivers is usually gradual, but often an abrupt decrease in characteristic grain size occurs from about 10 to 1 mm, i.e., a gravel-sand transition (GST) or gravel front. Here we present an analytical model of GST migration that explicitly accounts for gravel and sand transport and deposition in the gravel reach, sea level change, subsidence, and delta progradation. The model shows that even a limited gravel supply to a sand bed reach induces progradation of a gravel wedge and predicts the circumstances required for the gravel front to advance, retreat, and halt. Predicted modern GST migration rates agree well with measured data at Allt Dubhaig and the Fraser River, and the model qualitatively captures the behavior of other documented gravel fronts. The analysis shows that sea level change, subsidence, and delta progradation have a significant impact on the GST position in lowland rivers.

    1994-12-31

    This report summarizes a portion of the ongoing Fraser River Action Plan investigations of pulp mill effluent effects on aquatic life. The report presents the results of a toxicity experiment using bleached kraft mill effluent from a mill on the Thompson River in Kamloops, British Columbia. This effluent has the potential for both nutrient enrichment and toxic effects on aquatic ecosystems. The experiment was designed as a first attempt to examine the relative nature of these two effects as determined by the response to the effluent of the mayfly, an abundant benthic macroinvertebrate in the river. Food-dependent effects were determined by exposing the mayflies to effluent for two weeks within artificial streams arranged in a 2x3 factorial design. Responses measured included survival, growth, and development. Possible mechanisms for the responses are discussed.

    Rare Isotope Beam (RIB) facilities around the world, such as TRIUMF, work towards development of new target materials to generate exotic species. Access to these rare radioactive isotopes is key for applications in nuclear medicine, astrophysics and fundamental nuclear science. To better understand production from these and other materials, we have built a computer simulation of the RIB targets used at the TRIUMF Isotope Separation and ACceleration (ISAC) facility, to support new target material development. Built at Simon Fraser University, the simulation runs in the GEANT4 nuclear transport toolkit, and can simulate the production rate of isotopes from a given set of beam and target characteristics. The simulation models the bombardment of a production target by an incident high-energy proton beam and calculates isotope in-target production rates different nuclear reactions. Results from the simulation will be presented, along with an evaluation of various nuclear reaction models and a experimentally determined RIB yields at the ISAC Yield Station.

    Federal, state, and tribal fishery managers, as well as the general public and their elected representatives in the United States, were concerned when infectious salmon anemia virus (ISAV) was suspected for the first time in free-ranging Pacific Salmon collected from the coastal areas of British Columbia, Canada. This article documents how national and regional fishery managers and fish health specialists of the U.S. worked together and planned and implemented actions in response to the reported finding of ISAV in British Columbia. To date, the reports by Simon Fraser University remain unconfirmed and preliminary results from collaborative U.S. surveillance indicate that there is no evidence of ISAV in U.S. populations of free-ranging or marine-farmed salmonids on the west coast of North America.

    This paper suggested that Canada can play a leading role in the development of hydrogen railways. Canadian scientists were among the first to test and develop the world's first hydrogen locomotive, and Canadian rail firms are now in a position to play a prominent role in the passenger hydrogen rail equipment market. A hydrogen railway will be built as part of Vancouver's 2010 winter olympics infrastructure. The Fraser Valley Heritage Railway Society is planning to use hydrogen to power vintage inter-urban trolley cars connecting Surrey communities. A Canadian manufactured hybrid locomotive will be modified to create the world's first hydrogen rail switch engine. It was concluded that hydrogen's storage capacity makes it an enabling technology for other other renewable energy technologies. Future hydrogen storage technologies will probably be hybridized with fuel cells in highly efficient applications. 1 ref.

  16. Achieving Citizenship and Recognition through Blogging about Homelessness

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available This article describes a blog written by four men who were homeless in a western Canadian city in 2010. The blog was an attempt to promote communication between homeless people and the domiciled public, to assert the agency of homeless people, and to promote social integration through their participation in public discourse about homelessness. The bloggers explicitly set out to engage in civic action. In doing this they positioned themselves as advocates and therefore citizens—people with the right and responsibility to describe the “realities” of homelessness, critique existing social structures, take part in public dialogue about homelessness, advocate for change, and stand up for homeless people. This was a subject position that was not previously available to them. The blog project is an example of “lived citizenship,” citizenship as active participatory practice, and a way to achieve what Nancy Fraser calls a politics of recognition.

  18. Reading the ideological subtext in André Brink’s An Instant in the Wind and Patrick White’s A Fringe of Leaves

    Directory of Open Access Journals (Sweden)

    M. Wenzel

    2001-08-01

    Full Text Available From a postcolonial perspective, the simultaneous publication of André Brink’s An Instant in the Wind and Patrick White’s A Fringe of Leaves provides an interesting example of rewriting. Although both texts refer to the original story of Eliza Fraser that has featured in several genres, they approach the event from different historical time-frames. This article attempts to indicate that the contextual and formal similarities between the two novels are underpinned by different ideological subtexts that clearly manifest the respective authors’ preoccupations and their unconscious reactions to socio-political contexts. It would seem that Brink’s main concern lies with race relations, while White is more engrossed with gender issues.

    We have analyzed the first 3.75 years of data from the Taiwanese American Occultation Survey (TAOS). TAOS monitors bright stars to search for occultations by Kuiper Belt objects (KBOs). This data set comprises 5 x 10 5 star hours of multi-telescope photometric data taken at 4 or 5 Hz. No events consistent with KBO occultations were found in this data set. We compute the number of events expected for the Kuiper Belt formation and evolution models of Pan and Sari, Kenyon and Bromley, Benavidez and Campo Bagatin, and Fraser. A comparison with the upper limits we derive from our data constrains the parameter space of these models. This is the first detailed comparison of models of the KBO size distribution with data from an occultation survey. Our results suggest that the KBO population is composed of objects with low internal strength and that planetary migration played a role in the shaping of the size distribution.

    Full Text Available In this work we propose to analyze the mediated debate on Maria da Penha Law in the newspapers Folha de São Paulo and O Globo, during the period 2001-2012. We use here the “deliberative” theoretical matrix, taking in consideration and dialoguing with the critiques of feminist theoreticians (Nancy Fraser and Iris Young, in particular who have inscribed such a conception in democratic theory. We defend that oppression which originates from gender inequalities cannot do without public debate. Thus, we seek to identify how the arguments and discursive relations on Maria da Penha Law were constructed in the two newspapers in question in two distinct periods: the phase of the construction of the law (2001-2005, and that of its sanctioning and implementation (2006-2012. Our analysis is based on a qualitative methodology focusing on the study of deliberation and media, conjugated with a qualitative analysis framework.

    The use of "off-the-shelf" acoustic Doppler velocity profilers (ADCPs) to estimate suspended sediment concentration and grain-size in rivers requires robust methods to estimate sound attenuation by suspended sediment. Theoretical estimates of sediment attenuation require a priori knowledge of the concentration and grain-size distribution (GSD), making the method impractical to apply in routine monitoring programs. In situ methods use acoustic backscatter profile slope to estimate sediment attenuation, and are a more attractive option. However, the performance of in situ sediment attenuation methods has not been extensively compared to theoretical methods. We used three collocated horizontally mounted ADCPs in the Fraser River at Mission, British Columbia and 298 observations of concentration and GSD along the acoustic beams to calculate theoretical and in situ sediment attenuation. Conversion of acoustic intensity from counts to decibels is influenced by the instrument noise floor, which affects the backscatter profile shape and therefore in situ attenuation. We develop a method that converts counts to decibels to maximize profile length, which is useful in rivers where cross-channel acoustic profile penetration is a fraction of total channel width. Nevertheless, the agreement between theoretical and in situ attenuation is poor at low concentrations because cross-stream gradients in concentration, sediment size or GSD can develop, which affect the backscatter profiles. We establish threshold concentrations below which in situ attenuation is unreliable in Fraser River. Our results call for careful examination of cross-stream changes in suspended sediment characteristics and acoustic profiles across a range of flows before in situ attenuation methods are applied in river monitoring programs.

    The Mississippian Derbyshire Platform, located in the Pennine Basin of Northern England was deposited due to the back-arc extension during subduction of the Rheic Ocean. Platform growth was strongly affected by a pre-existing Caledonian structural pattern, and regional stresses related to the two main tectonic phases: (i) Mississippian rifting and (ii) Pennsylvanian-early Permian shortening associated with the Variscan Orogeny. The rifting stage was associated with N-S extension and resulted in development of WNW-ESE, W-E oriented grabens along a series of NW-SE and NE-SW trending faults. These faults were inherited from the pre-existing pattern of Caledonian structural weaknesses, and were likely to be reactivated during both rifting and orogenic tectonic stages. Seismic profiles across the studied area show evidence of Carboniferous extensional growth faulting and inversion during Variscan shortening (Fraser and Gawthorpe, 1990). Field analyses include characterization of faults orientation, kinematics and their crosscutting relationships. Additionally, lineament analysis of satellite images and structural maps was performed and structural elements of different hierarchies were recognized. Based on these analyses, the importance of strike-slip tectonics as a result of reactivation of earlier-formed Caledonian structural weaknesses is highlighted. The Derbyshire platform, therefore, emphasizes the controls of pre-existing structural pattern on a carbonate platform growth, geometry, structural architecture and facies distribution. As such, understanding the full tectonic history, and preceding tectonic events specifically, is crucial for understanding structural controls on platform growth.

    The red spruce-Fraser fir ecosystem [Picea rubens Sarg.-Abies fraseri (Pursh) Poir.] of the southern Appalachian mountains, USA, is a temperate zone cloud forest immersed in clouds for 30-40% of a typical summer day, and experiencing immersion on about 65% of all days annually. We compared the microclimate, photosynthetic gas exchange, and water relations of Fraser fir trees in open areas during cloud-immersed, low-cloud, or sunny periods. In contrast to sunny periods, cloud immersion reduced instantaneous sunlight irradiance by 10-50%, and midday atmospheric vapor pressure deficit (VPD) was 85% lower. Needle surfaces were wet for up to 16 h per day during cloud-immersed days compared to <1 h for clear days. Shoot-level light-saturated photosynthesis (A (sat)) on both cloud-immersed (16.0 micromol m(-2) s(-1)) and low-cloud (17.9 micromol m(-2) s(-1)) days was greater than A (sat) on sunny days (14.4 micromol m(-2) s(-1)). Daily mean A was lowest on cloud-immersed days due to reduced sunlight levels, while leaf conductance (g) was significantly higher, with a mean value of 0.30 mol m(-2) s(-1). These g values were greater than commonly reported for conifer tree species with needle-like leaves, and declined exponentially with increasing leaf-to-air VPD. Daily mean transpiration (E) on immersed days was 43 and 20% lower compared to sunny and low-cloud days, respectively. As a result, daily mean water use efficiency (A/E) was lowest on cloud-immersed days due to light limitation of A, and high humidity resulted in greater uncoupling of A from g. Thus, substantial differences in photosynthetic CO2 uptake, and corresponding water relations, were strongly associated with cloud conditions that occur over substantial periods of the summer growth season.

Dans cet article, on cherche à examiner de façon critique les théories de Nancy Fraser et Axel Honneth pour tenter d'approfondir la compréhension de la façon dont s'est établie au Brésil une hiérarchie de status basée sur la question de race incorporant des éléments de l'espace public, social et privé. On montre ici, dans les formes de stratification raciale aux États-Unis et au Brésil, un ensemble de distinctions qui ne peuvent se restreindre au déplacement racial existant au Brésil. On attribue cette opposition à des traditions de régulation légale variées. On discute aussi les différentes traditions d'intégration raciale et d'action affirmative dans les deux pays tout en essayant d'éclairer les déficits conceptuels des théories qui n'envisagent l'intégration raciale qu'à partir de la sphère privée. Pour finir, on propose un modèle de reconnaissance intégrant les théories de Fraser et Honneth et associant l'attribution de statut légal à des segments raciaux historiquement rabaissés à une politique œuvrant pour la formation de l'estime de soi.

  6. Field experience in science for fifth grade students---a mixed methods study of learning environments

    Patterson, Barbara E.

    The purpose of this research is to compare students' perceptions of the learning environment in a traditional science classroom and a field study classroom. This mixed methods study used a sequential explanatory design. Phase one was the quantitative phase using two survey tools. A modified version of the "What is happening in this Classroom Survey" (WIHIC) (Fraser et al., 1996) and the "Test of Science Related Attitudes" (TOSRA) (Fraser, 1982) was administered to 60 fifth grade students from one school. Data was then disaggregated by socioeconomic class and ethnicity. Results from Phase one showed that students prefer the classroom for investigation and prefer the field environment for enjoyment of science. Differences in ethnicity and class were small but Hispanic students prefer the field for investigation and equity. Students that are low socio-economic class rank cooperation in the field higher than the classroom and students that do not qualify for free or reduced lunch prefer the field environment for enjoyment of science. Finally, there are strong correlations for the variables of cooperation, investigation, equity and enjoyment of science in both the classroom and the field environment. Questions raised from the analysis of the survey data were further explored through qualitative data collection methods in phase two. Student responses to three questions were coded using template analysis to provide answers to the "how and why" field experience effects students' attitudes toward science. Three themes emerged from the coding of the results. These results showed that students are physically engaged, develop a sense of place and learn skills in the field that reinforce concepts learned in the classroom. This information will help teachers in developing quality and meaningful experiences for all students.

    Osprey (Pandion haliaetus) eggs were collected during 1995 and 1996 at seven sites along the Fraser and Columbia River systems of British Columbia, Canada, and Washington and Oregon, USA. Fifty-four eggs were placed into a laboratory incubator. Thirty-eight of the hatched chicks were sacrificed within 24 h. Hatching success did not differ among sites and therefore between treatment and reference areas. Residual yolk sacs of eggs collected downstream of the large bleached-kraft pulp mill at Castlegar contained greater mean concentrations of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, 2,930 ng/kg lipid) compared with reference sites such as the Nechako River, an upper tributary of the Fraser system (33.7 ng/kg). Total polychlorinated biphenyls (PCBs) in yolk sacs were also higher at Castlegar and in samples from the Columbia River downstream of Portland, Oregon, compared with those from the Nechako River. Concentrations of measured chemicals, including TCDD toxic equivalents (TEQs), total PCBs, p,p'-dichlorodiphenylethylene (p,p'-DDE), and other organochlorines were not different in eggs that failed to hatch compared with calculated whole-egg values for hatched eggs. There were significant biochemical responses; a hepatic cytochrome P4501A (CYP1A) cross-reactive protein was detected in all samples tested and correlated positively with ethoxyresorufin o-deethylase (EROD) activity and yolk sac concentrations of TEQs and total PCBs. Tissue concentrations of vitamin A compounds varied among sites and correlated positively with yolk sac concentrations of TEQs and PCBs. Morphological, histological, and other physiological parameters, including chick growth, edema, deformities, and hepatic and renal porphyrin concentrations, neither varied among sites nor showed concentration-related effects.

    Full Text Available Background: Professional midwives have an important role to play in midwifery training to produce a competent midwife. According to the social learning theory, professional midwives act as role models for students. When allocated for clinical learning experiences in the training hospitals, students will have the opportunity to observe the well-trained, skilled, and experienced professional midwives. The whole process will enable students to integrate theory with practice and they will become competent.Aim: The aim of this study was to determine the factors affecting integration of midwifery nursing science theory with clinical practice as perceived by midwives.Setting: The study was conducted at the training hospitals in Vhembe district of the Limpopo Province, South Africa. These hospitals were: Donald Fraser, Siloam, and Tshidzini.Methods: A qualitative explorative, descriptive and contextual design was used. A Nonprobability, convenient sampling method was used to select 11 midwives from the following hospitals: Donald Fraser, Siloam, and Tshidzini, in Vhembe district. In-depth individual interviews were conducted. Data were analysed through open coding method.Result: One theme and five sub-themes emerged from the analysed data, namely: shortage of midwives, attitudes towards student midwives, reluctance to perform teaching functions, language barriers, and declining midwifery practice standards.Conclusion: Shortage of midwives in the clinical areas led to fewer numbers of mentors whom the students could observe and imitate to acquire clinical skills. Some of the midwives were reluctant to teach students. Recommendations were made for both training institutions and hospitals to employ preceptors for students in the clinical practical.

  9. Energy Technologies for the West: possible effects of energy technology on land, water, and air resources. Workshop held in San Francisco, California, 21 September 1976

    Energy Technology Data Exchange (ETDEWEB)

    1976-01-01

    John Fraser, Association of California Water Agencies, spoke on the effect of energy technology on California's water resources. He pointed out that by the year 2000, a water deficiency of about 2,250,000 acre-feet will exist in California; therefore, many agencies will not indefinitely commit supplies of fresh water for power plant cooling. Legislation for siting power plants along the coastline is summarized. Dr. James Liverman, ERDA, noted a remark by Mr. Fraser that, in its national plan, ERDA ''does not appear to pay much attention to the water issue''; he agrees, but says ERDA is committed to working with the Water Resources Council, with establishments in each state. Professor Robert Hagan, Univ. of California, reports on a program to investigate the energy required to develop water, or, in short, to move water to where it is to be used; water which may be associated with the use and conservation of water; the energy associated with waste-water treatment; and waste-water reuse. Speaker Zock Willey, Environmental Defense Fund, briefly evaluated the environmental impact of an energy technology by saying that the public has a right to know and say what the risks are in terms of the trade-offs. Russ Freeman, EIA, says he doesn't believe it possible to have an energy program in the traditional concept of a government program. EPA has learned that energy is an input to every societal process and pollution is an output from virtually everything that society does. The final speaker, Fayne L. Tucker, Lake County Air Pollution Control District, reviewed the potential of geothermal resources, saying that it is believed the Lake County government can, with the state and Federal government, plan geothermal development. It is also believed the Geysers should be considered as a payoff area. An extensive question and answer session completed the workshop. (MCW)

  10. Reproductive success and chlorinated hydrocarbon contamination of resident great blue herons (Ardea herodias) from coastal British Columbia, Canada, 1977 to 2000

    Human disturbance and loss of nesting habitat were more important factors than chlorinated hydrocarbons in changing heron reproductive success. - Over the period 1977-2000, eggs of Pacific great blue heron (Ardea herodias fannini) were collected from 23 colonies along the southern coast of British Columbia, Canada, and analyzed for persistent organochlorine (OC) pesticides and polychlorinated biphenyls (PCBs). Concentrations of OC pesticides in eggs declined sharply in the late 1970s, after which there were minimal changes. The sums of PCB congeners were not reduced appreciably during the 1980s and 1990s, but Aroclor 1260 concentrations suggested a sharp decline in PCB contamination of eggs in the late 1970s, similar to that shown for OC pesticides. Eggs collected along or near the Fraser River delta showed higher levels of most pesticides compared to other monitored colonies. Although the delta lands support a long-standing agricultural economy, the primary factors influencing OC levels in the delta colonies were thought to be driven by estuarine processes. We suggest two possible influencing factors were: 1) a greater rate of bioaccumulation in the estuary due to the deposition of particulates collected over a vast area encompassed by the Fraser River watershed; or 2) a higher rate of biomagnification in the estuary due to species differences at lower trophic levels of the heron food chain. Eggs from urban colonies contained higher levels of PCBs. The congener pattern was not clearly different from that observed in less contaminated eggs from rural and pulp mill-influenced colonies, except that colonies in Vancouver had greater proportions of PCB-66, suggesting a local source of Aroclor 1242. Productivity in the coastal heron colonies was highly variable over the period of study, with 71% of recorded colony-wide reproductive failures occurring in colonies near pulp mills. However, the predominant factors influencing reproductive success were probably disturbance

    We assessed chlorinated hydrocarbon contamination of mink and river otters on the Columbia and Fraser River systems of northwestern North America, in relation to morphological measures of condition. We obtained carcasses of mink and river otters from commercial trappers during the winters 1994-1995 and 1995-1996. Necropsies included evaluation of the following biological parameters: sex, body mass and length, age, thymus, heart, liver, lung, spleen, pancreas, kidney, gonad, omentum, adrenal gland and baculum masses, baculum length, and stomach contents. Livers were analyzed, individually or in pools, for residues of organochlorine (OC) pesticides, polychlorinated biphenyls (PCBs), dibenzo-p-dioxins, and dibenzofurans. Contaminant levels were relatively low compared to those documented in other North American populations, although they ranged higher than those detected during an earlier survey (1990-1992) of these regional populations. Body condition varied slightly among collection regions, but showed no relationship with contaminant burden. Mink from the upper Fraser River had less fat stores and also had some of the lowest OC contamination levels observed. Similarly, a few individuals with enlarged livers and kidneys had low contaminant levels. Although a few individual animals with gross abnormalities of reproductive systems did not show high levels of contamination, there was a significant negative correlation between total PCB concentrations (as Aroclor 1260) and baculum length in juvenile mink (r = 0.707; p = 0.033; n = 8). The association of juvenile baculum length with eventual reproductive success is unknown, but further characterization of reproductive organ morphology and relationship to contaminants should be undertaken in a larger subset of these populations.

    Among the most frequently cited reports in the science of earthquake prediction is that by Fraser-Smith et al. (1990) and Bernardi et al. (1991). They found anomalous enhancement of magnetic-field noise levels prior to the 18 October 1989 Loma Prieta earthquake in the ultra-low-frequency range (0.0110-10.001 Hz) from a ground-based sensor at Corralitos, CA, just 7 km from the earthquake epicenter. In this analysis, we re-examine all of the available Corralitos data (21 months from January 1989 to October 1990) and the logbook kept during this extended operational period. We also examine 1.0-Hz (1-s) data collected from Japan, 0.0167-Hz (1-min) data collected from the Fresno, CA magnetic observatory, and the global Kp magnetic-activity index. The Japanese data are of particular importance since their acquisition rate is sufficient to allow direct comparison with the lower-frequency bands of the Corralitos data. We identify numerous problems in the Corralitos data, evident from both straightforward examination of the Corralitos data on their own and by comparison with the Japanese and Fresno data sets. The most notable problems are changes in the baseline noise levels occurring during both the reported precursory period and at other times long before and after the earthquake. We conclude that the reported anomalous magnetic noise identified by Fraser-Smith et al. and Bernardi et al. is not related to the Loma Prieta earthquake but is an artifact of sensor-system malfunction. ?? 2008 Elsevier B.V.

    The protozoan pathogen Neospora caninum is recognized as a leading cause of infectious abortions in cattle worldwide. To evaluate the impact of neosporosis on dairy and beef herd production, a retrospective, longitudinal study was performed to identify the impact of neosporosis alongside other causes of fetal abortion in British Columbia, Canada. Retrospective analysis of pathology records of bovine fetal submissions submitted to the Animal Health Centre, Abbotsford, British Columbia, a provincial veterinary diagnostic laboratory, from January 2007– July 2013 identified 182 abortion cases (passive surveillance). From July 2013–May 2014, an active surveillance program identified a further 54 abortion cases from dairy farmers in the Upper Fraser Valley, British Columbia. Of the total 236 fetal submissions analyzed, N. caninum was diagnosed in 18.2% of cases, making it the most commonly identified infectious agent associated with fetal loss. During active surveillance, N. caninum was associated with 41% of fetuses submitted compared to 13.3% during passive surveillance (P<0.001). Breed of dam was significantly associated with N. caninum diagnosis, with a higher prevalence in dairy versus beef breeds, and fetuses of 3–6 months gestational age had the highest prevalence of N. caninum. There was no significant association with dam parity. Neospora caninum was diagnosed in every year except 2009 and cases were geographically widespread throughout the province. Furthermore, the active surveillance program demonstrates that N. caninum is highly prevalent in the Upper Fraser Valley and is a major causal agent of production losses in this dairy intensive region.

    Environmental shifts accompanying salmon spawning migrations from ocean feeding grounds to natal freshwater streams can be severe, with the underlying stress often cited as a cause of increased mortality. Here, a salmonid microarray was used to characterize changes in gene expression occurring between ocean and river habitats in gill and liver tissues of wild migrating sockeye salmon (Oncorhynchus nerka Walbaum) returning to spawn in the Fraser River, British Columbia, Canada. Expression profiles indicate that the transcriptome of migrating salmon is strongly affected by shifting abiotic and biotic conditions encountered along migration routes. Conspicuous shifts in gene expression associated with changing salinity, temperature, pathogen exposure and dissolved oxygen indicate that these environmental variables most strongly impact physiology during spawning migrations. Notably, transcriptional changes related to osmoregulation were largely preparatory and occurred well before salmon encountered freshwater. In the river environment, differential expression of genes linked with elevated temperatures indicated that thermal regimes within the Fraser River are approaching tolerance limits for adult salmon. To empirically correlate gene expression with survival, biopsy sampling of gill tissue and transcriptomic profiling were combined with telemetry. Many genes correlated with environmental variables were differentially expressed between premature mortalities and successful migrants. Parametric survival analyses demonstrated a broad-scale transcriptional regulator, cofactor required for Sp1 transcriptional activation (CRSP), to be significantly predictive of survival. As the environmental characteristics of salmon habitats continue to change, establishing how current environmental conditions influence salmon physiology under natural conditions is critical to conserving this ecologically and economically important fish species. © 2011 Blackwell Publishing Ltd.

    Nutrient uptake capacity is an important parameter in modeling nutrient uptake by plants. Researchers commonly assume that uptake capacity measured for a species can be used across sites. We tested this assumption by measuring the nutrient uptake capacity of intact roots of Engelmann spruce (Picea engelmanni Parry) and subalpine fir (Abies lasiocarpa (Hook.) Nutt.) at Loch Vale Watershed and Fraser Experimental Forest in the Rocky Mountains of central Colorado. Roots still attached to the tree were exposed to one of three concentrations of nutrient solutions for time periods ranging from 1 to 96 hours, and solutions were analyzed for ammonium, nitrate, calcium, magnesium, and potassium. Surprisingly, the two species were indistinguishable in nutrient uptake within site for all nutrients (P > 0.25), but uptake rates differed by site. In general, nutrient uptake was higher at Fraser (P = 0.01, 0.15, 0.03, 0.18 for NH{sub 4}{sup +}, NO{sub 3}{sup -}, Ca{sup 2+}, and K{sup +}, respectively), which is west of the Continental Divide and has lower atmospheric deposition of N than Loch Vale. Mean uptake rates by site for ambient solution concentrations were 0.12 {micro}mol NH{sub 4}{sup +} g{sub fwt}{sup -1} h{sup -1}, 0.02 {micro}mol NO{sub 3}{sup -} g{sub fwt}{sup -1}, 0.21 {micro}mol Ca{sup 2+} g{sub fwt}{sup -1} h{sup -1}, and 0.01 {micro}mol Mg{sup 2+} g{sub fwt}{sup -1} h{sup -1} at Loch Vale, and 0.21 {micro}mol NH{sub 4}{sup +} f{sub fwt}{sup -1}h{sup -1}, 0.04 {micro}mol NO{sub 3}{sup -} g{sub fwt}{sup -1} h{sup -1}, 0.51 {micro}mol Ca{sup 2+}g{sub fwt}{sup -1}h{sup -1}, and 0.07 {micro}mol Mg{sup 2+} f{sub fwt}{sup -1}h{sup -1} at Fraser. The importance of site conditions in determining uptake capacity should not be overlooked when parameterizing nutrient uptake models. We also characterized the root morphology of these two species and compared them to other tree species we have measured at various sites in the northeastern USA. Engelman spruce and subalpine fir

    Full Text Available The paper discusses the issue of sexual violence against women during the past military dictatorships in Latin America, especially in Argentina, and some consequences in the current practice of their sexual and reproductive rights. It analyzes the extent the exercise of sexuality has a connection with the exercise of power, which organizes, manages, and prioritizes behavior depending on a political, social and cultural project, in a context of time and space. This means that the public and private, power and sexuality depend on the idea of the nation, class, race and religion, and consequently implies the political control of reproduction and the family model, including expressions of gender sexual violence. The paper discusses feminist theoretical concepts, such as the concept of gender and nation from an intersectional perspective (Yuval Davis, the idea of post colonialism and decolonization of feminism (Mohanty, and the relationship between gender and globalization (Fraser.

  20. 2H Stable Isotope Analysis of Tooth Enamel: A Pilot Study

    2010-05-01

    Stable isotope analysis of biogenic tissues such as tooth enamel and bone mineral has become a well recognized and increasingly important method for determining provenance of human remains, and has been used successfully in bioarchaeological studies as well as forensic investigations (Lee-Thorp, 2008; Meier-Augenstein and Fraser, 2008). Particularly, 18O and 2H stable isotopes are well established proxies as environmental indicators of climate (temperature) and source water and are therefore considered as indicators of geographic life trajectories of animals and humans (Hobson et al., 2004; Schwarcz and Walker, 2006). While methodology for 2H analysis of human hair, fingernails, and bone collagen is currently used to determine geographic origin and identify possible migration patterns, studies involving the analysis of 2H in tooth enamel appear to be nonexistent in the scientific literature. The apparent lack of research in this area is believed to have two main reasons. (1) Compared to the mineral calcium hydroxylapatite Ca10(PO4)6(OH)2, in tooth enamel forming bio-apatite carbonate ions replace some of the hydroxyl ions at a rate of one CO32 replacing two OH, yet published figures for the degree of substitution vary (Wopenka and Pasteris, 2005). (2) Most probably due to the aforementioned no published protocols exist for sample preparation and analytical method to obtain δ2H-values from the hydroxyl fraction of tooth enamel. This dilemma has been addressed through a pilot study to establish feasibility of 2H stable isotope analysis of ground tooth enamel by continuous-flow isotope ratio mass spectrometry (IRMS) coupled on-line to a high-temperature conversion elemental analyzer (TC/EA). An array of archaeological and modern teeth has been analyzed under different experimental conditions, and results from this pilot study are being presented. References: Lee-Thorp, J.A.

    Aim: The present study was undertaken with the prime objective of isolating and identifying Listeria spp. from various foods of animal origin sold at retail market outlets in the city of Navsari, Gujarat. Materials and Methods: Total 200 samples comprising of milk, milk products, meat, and fish (50 each) collected aseptically from local market which were subjected first to pre-enrichment in half strength Fraser broth followed by enrichment in full strength Fraser broth and subsequent plating on PALCAM agar. The growth with the typical colony characteristics were further identified up to species level on the basis of their morphological and biochemical characteristics. Cultures identified as Listeria monocytogenes were further subjected to in vitro pathogenicity tests and detection of different virulence-associated genes viz. actA, hlyA, and iap using polymerase chain reaction. Results: Of the total 200 food samples of animal origin; 18 (9%) were found positive for Listeria spp. which were identified as Listeria seeligeri (6, 33.3%), Listeria innocua (5, 27.7%), Listeria welshimeri (4, 22.2%), and L. monocytogenes (3, 16.6%). The highest prevalence was observed in milk samples (8). Species wise, 6 isolates of L. seeligeri which included two each from cow milk, buffalo milk, and meat samples; 5 L. innocua isolates included four recovered from fish and one from meat sample; 4 L. welshimeri comprised of two isolates from ice cream and one each from buffalo milk and meat sample; and 3 isolates of L. monocytogenes recovered from milk (1 cow and 2 buffalo milk). All 3 L. monocytogenes isolates screened for the presence of virulence genes viz. actA, hlyA, and iap using the specific primers revealed the presence of all the genes suggesting the possibility of danger of foodborne listeriosis among raw milk consumers. Conclusion: Listeria spp. was isolated from 9% (18/200) of the animal origin food samples viz.; milk, milk products, meat, and fish with the highest prevalence

    Full Text Available The discussion about the legitimacy of architecture being an autonomous discipline or a part of an interrelated system of areas of knowledge has been long discussed[i]. This article connects the scenario described by Fraser[ii] and Wigley[iii] where architecture needs to be considered in an expanded field as consequence of the post-critical period, to the work of a new generation of architects whose interest lies on questions that are peripheral to architecture sensu stricto. The type of architecture that emerges in this scenario is characterised by a proclivity towards other disciplines, including politics, economics and social studies. The article presents a series of examples of recent projects and discusses the impact of their approach to architecture. As a conclusion, this paper proposes the notion of mediocritas to establish a right balance between architecture as an autonomous discipline and its contamination with other cultural fields.

  4. Overview of Ground-Motion Issues for Cascadia Megathrust Events: Simulation of Ground-Motions and Earthquake Site Response

    Full Text Available Ground motions for earthquakes of M7.5 to 9.0 on the Cascadia subduction interface are simulated based on a stochastic finite-fault model and used to estimate average response spectra for reference firm soil conditions. The simulations are first validated by modeling the wealth of ground-motion data from the 2011 M9.0 Tohoku earthquake of Japan. Adjustments to the calibrated model are then made to consider average source, attenuation and site parameters for the Cascadia region. This includes an evaluation of the likely variability in stress drop for large interface earthquakes and an assessment of regional attenuation and site effects. We perform best-estimate simulations for a preferred set of input parameters. Typical results suggest mean values of 5%-damped pseudoacceleration in the range from about 100 to 200 cm/s2, at frequencies from 1 to 4 Hz, for firm-ground conditions in Vancouver. Uncertainty in most-likely value of the parameter representing stress drop causes variability in simulated response spectra of about ±50%. Uncertainties in the attenuation model produce even larger variability in response spectral amplitudes—a factor of about two at a closest distance to the rupture plane (Rcd of 100 km, becoming even larger at greater distances. It is thus important to establish the regional attenuation model for ground-motion simulations and to bound the source properties controlling radiation of ground motion. We calculate theoretical one-dimensional spectral amplification estimates for four selected Fraser River Delta sites to show how the presence of softer sediments in the region may alter the predicted ground motions. The amplification functions are largely consistent with observed spectral amplification at Fraser River delta sites, suggesting amplification by factors of 2.5–5 at the peak frequency of the site; we note that deep sites in the delta have a low peak frequency, ∼0.3 Hz. This work will aid in seismic hazard

    ) parameters are fixed in the inversion. Bayesian inversion of microtremor array data is applied at two sites in British Columbia, the area of highest seismic risk in Canada, to study the ability to recover an accurate VS profile in relatively deep and shallow geological settings on the Fraser River delta in Greater Vancouver and in Victoria, respectively. A well-resolved VS profile to at least 110 m depth is determined at the Fraser River delta site for a power-law gradient parametrization. At the Victoria site, a layer with low VS and a weak linear gradient is indicated to 15-18 m depth, above much higher velocity material. Invasive VS measurements from seismic cone penetration testing and/or surface-to-downhole methods are used to assess the reliability of the Bayesian microtremor inversion results, with excellent agreement obtained at both sites.

    Climate change is impacting global surface water resources, increasing the need for a deeper understanding of the interaction between climate and biological diversity. This is particularly the case in the Southern Hemisphere sub-tropics, where little information exists on the aquatic biota response to climate variations. Palaeolimnological techniques, in particular the use of diatoms, are well established and can significantly contribute to the understanding of climatic variability and the impacts that change in climate have on aquatic ecosystems. A sediment core from Lake McKenzie, Fraser Island (Australia), was used to investigate interactions between climate influences and aquatic ecosystems. This study utilises a combination of proxies including biological (diatom), geochemical and chronological techniques to investigate long-term aquatic changes within the perched-dune lake. A combination of {sup 210}Pb and AMS {sup 14}C dates showed that the retrieved sediment represented a history of ca. 37,000 cal. yBP. The sedimentation rate in Lake McKenzie is very low, ranging on average from 0.11 mm to 0.26 mm per year. A sediment hiatus was observed between ca. 18,300 and 14,000 cal. yBP suggesting a period of dry conditions at the site. The diatom record shows little variability over the period of record, with benthic, freshwater acidic tolerant species dominating. Relative abundance of planktonic species and geochemical results indicates a period of increased water depth and lake productivity in the early Holocene and a gradual decrease in effective precipitation throughout the Holocene. Results from this study not only support earlier work conducted on Fraser Island using pollen reconstructions but also demonstrate that diatom community diversity has been relatively consistent throughout the Holocene and late Pleistocene with only minor cyclical fluctuation evident. This record is consistent with the few other aquatic palaeoecological records from the Southern

    Full Text Available This study aims to determine if large-scale choked panel destress blasting can provide sufficient beneficial stress reduction in highly-stressed remnant ore pillar that is planned for production. The orebody is divided into 20 stopes over 2 levels, and 2 panels are choke-blasted in the hanging wall to shield the ore pillar by creating a stress shadow around it. A linear-elastic model of the mining system is constructed with finite difference code FLAC3D. The effect of destress blasting in the panels is simulated by applying a fragmentation factor (α to the rock mass stiffness and a stress reduction factor (β to the current state of stress in the region occupied by the destress panels. As an extreme case, the destress panel is also modeled as a void to obtain the maximum possible beneficial effects of destressing and stress shadow. Four stopes are mined in the stress shadow of the panels in 6 lifts and then backfilled. The effect of destress blasting on the remnant ore pillar is quantified based on stress change and brittle shear ratio (BSR in the stress shadow zone compared to the base case without destress blasting. To establish realistic rock fragmentation and stress reduction factors, model results are compared to measured stress changes reported for case studies at Fraser and Brunswick mines. A 1.5 MPa immediate stress decrease was observed 20 m away from the panel at Fraser Mine, and a 4 MPa immediate stress decrease was observed 25 m away at Brunswick Mine. Comparable results are obtained from the current model with a rock fragmentation factor α of 0.2 and a stress reduction factor β of 0.8. It is shown that a destress blasting with these parameters reduces the major principal stress in the nearest stopes by 10–25 MPa. This yields an immediate reduction of BSR, which is deemed sufficient to reduce volume of ore at risk in the pillar.

  9. Emission trading: A discussion paper

    International Nuclear Information System (INIS)

    1992-05-01

    Emission trading is a market-based incentive program designed to control air emissions in which a cap is placed on the total quantity of pollutants allowed to be emitted in an airshed. Appropriate shares of this amount are allocated among participating emission sources, and participants can buy or sell their shares. Advantages of emission trading include its potential to achieve air emission targets at a lower cost than the traditional command and control approach, and its ability to accommodate economic growth without compromising environmental quality. A study was conducted to evaluate the potential use of emission trading programs to achieve emission reduction goals set for nitrogen oxides, volatile organic compounds (VOC), and sulfur oxides. Emission trading programs in the USA are reviewed and a set of factors important for the success of emission trading are identified. Key policy and design issues related to an emission trading program are identified, explained, and discussed. Administrative issues are then analyzed, such as legislative authority, monitoring and enforcement requirements, and trading between jurisdictions. A preliminary assessment of emission trading for control of NOx and VOC in the Lower Fraser Valley indicates that emission trading would be feasible, but legislative authority to implement such a program would have to be introduced

    An insect and desease survey initiated in 1985 on 100 permanent plots has yielded little significant pathology or insect infestation. With the exception the balsam wooly adelgid, few signs or symptoms of disease or insect attack were noted on either Fraser fir or red spruce populations. Cultures from destructively-sampled root systems yielded few significant pathogens that could be attributed to decline symptoms. Measurements of throughfall in 1986 yielded estimates of total wet deposition for NO -3 and SO 4 -2 of 25 and 75 kg ha -1 yr -1 , respectively. Cloud and rain water was dominated by H + , NH +4 , NO -3 , and SO 4 -2 ions. Interaction with the forest canopy resulted in an enrichment of throughfall with base cations (K + , Ca +2 , and MG +2 ) and a loss of H + and NH +4 . Mean-volume-weighted pH for throughfall was 3.9. The effects of simulated acidic cloud water on the epicuticular waxes of red spruce needles were studied during the summer of 1987. The cuticle proper of both 1986 and 1987 needles did not appear to be damaged by the treatments. The wax crystals which consititute the stomatal wax plugs, however, exhibited substantial degradation by simulated treatments at or below pH 3.5. (orig./VT)

    This essay reviews four texts which critically analyse methadone maintenance therapy using Foucault as a key theoretical framework: [Friedman, J., & Alicea, M. (2001). Surviving heroin: Interviews with women in methadone clinics. Florida: University Press of Florida], [Bourgois, P. (2000). Disciplining addictions: The bio-politics of methadone and heroin in the United States. Culture Medicine and Psychiatry, 24, 165-195], [Bull, M. (2008). Governing the heroin trade: From treaties to treatment. Ashgate: Aldershot], and [Fraser, S., & valentine, k. (2008). Substance & substitution: Methadone subjects in liberal societies. New York: Palgrave Macmillan]. Taken together these works demonstrate one trajectory in the development of critical drug studies over the past decade. While all four view MMT as a regulatory technology which aims to create productive and obedient subjects, their understandings of the power relations of the clinic are quite distinct. The first two texts emphasise the social control of drug users, the third, issues of governmentality and liberal political practice, while the fourth engages with ontological questions about substances themselves. Thus while Foucauldian analysis has become familiar in social studies of drugs and alcohol, new uses for its conceptual tools continue to emerge.

  12. Political representation for social justice in nursing: lessons learned from participant research with destitute asylum seekers in the UK.

    2016-09-01

    The concept of social justice is making a revival in nursing scholarship, in part in response to widening health inequalities and inequities in high-income countries. In particular, critical nurse scholars have sought to develop participatory research methods using peer researchers to represent the 'voice' of people who are living in marginalized spaces in society. The aim of this paper is to report on the experiences of nurse and peer researchers as part of a project to explore the experiences of people who find themselves destitute following the asylum process in the UK. In seeking to explore social injustice, three challenges are identified: lack of a robust political theory, institutional/professional constraints and an absence of skills to engage with the politics of social (in)justice. Each challenge is presented, opposing voices outlined and some possible solutions are suggested. The work of political theorist Nancy Fraser is used as a conceptual framework, in particular her focus on mis/framing and political representation for social justice. In addition, it is suggested that social justice needs to be further embedded in nursing policy and curriculum. Finally, nurses are encouraged to develop practical political skills to engage with both politics and the media in a neoliberal globalizing world. © 2016 John Wiley & Sons Ltd.

    2003-01-01

    The acronym for Canada's national laboratory for particle and nuclear physics, TRIUMF, was out of date almost as soon as it was coined. Derived from "TRI-University Meson Facility", it reflected the three universities - British Columbia, Victoria and Simon Fraser that initially conceived the Vancouver laboratory in 1965. Well before the proposal was approved in 1968, however, the University of Alberta had come on board, and today 11 Canadian universities belong to the TRIUMF club. The remainder of the acronym has also become rather misleading, since TRIUMF is now more than a meson facility. The laboratory's current activities include operating the radioactive beam facility, ISAC, and the coordination of Canada's role in the Large Hadron Collider (LHC) project at CERN. The TRIUMF cyclotron was built under the guidance of J Reginald Richardson, who studied under Ernest Lawrence at Berkeley. It produced its first beam in 1974. The cyclotron is literally at the heart of the laboratory, with a meson hall to one si...

    On 4th August 2014, the tailings impoundment of the Mount Polley copper and gold mine in British Columbia failed. Material from the impoundment (surface area = 2.7 km2) flowed into nearby Polley Lake and Hazeltine Creek, before discharging into Quesnel Lake, a large (ca. 100 km long, >500 m deep), relatively pristine lake. Estimates suggest that approximately 25 Mm3 of tailings (water and solids), in addition to eroded soils and surficial materials from Hazeltine Creek, were delivered to Quesnel Lake, raising the lake by 7.7 cm. Much of this material was deposited at the bottom of Quesnel Lake but a large plume of fine-grained sediment (d50 of ca. 1 µm) moved both up-lake towards important salmon spawning areas and down-lake into Quesnel River, which in turn flows into the Fraser River. This movement of the sediment plume is controlled by the physical limnology of the lake, especially seiche events. Samples of lake water and sediment samples taken from the impacted area show elevated levels of metals and other elements, which may have important implications for the ecosystem in this watershed (>11,000 km2). This presentation describes the failure and presents preliminary findings of the aquatic impacts of this environmental disaster.

    An experimental study of the polarization dependence of the photoelectric effect in cesium iodide in the soft X-ray band was started (Heckler et al., 1989). At a grazing angle of 10 degrees and a photon energy of 2.6 keV, it is found that the photoelectric yield from a thin layer of evaporated cesium iodide varies by 12.4 percent as the polarization vector of the incident X-ray beam is rotated about the line-of-sight. The rotation angle corresponding to the maximum photoyield is displaced by 16 degrees from the normal to the photocathode. This modulation and phase shift are in good agreement with the results recently reported by Fraser, et al. (1989) It is shown that a focal plane stellar X-ray polarimeter based on this photoelectric effect will be substantially more efficient than convential X-ray polarimeters such as those based on either Bragg reflection or scattering from low atomic number targets. 7 refs

    Red cell indices and discriminant functions were studied in 463 heterozygous beta-thalassaemics (337 without iron deficiency, 126 with iron deficiency) and 195 patients of iron deficiency anaemia (IDA) to ascertain their utility in the detection of betathalassaemia trait (BTT). Majority of traits in both groups had an elevated RBC count (> or = 5.0 x 10(12)/L). The counts were significantly higher than of patients with IDA, only 4.6% of whom had this degree of erythrocytosis. Mean Hb concentration was significantly higher in traits as compared to iron deficient subjects (p < 0.0001). Mean MCV and MCH were significantly (p < 0.0001) lower in traits more so in those with ID as compared to patients of IDA. MCV < 80 fl and MCH < 27 pg were found to be sensitive markers in the detection of traits even in the presence of ID. Of the four discriminant functions studied MCSQ was found to be most sensitive in detection of BTT and it identified 97.9% traits. DF of England and Fraser was most specific for BTT being < 8.4 in only 6.2% patients with IDA. Detection of erythrocytosis especially in the presence of mild anaemia and calculation of discriminant functions derived from red cell indices were found to play an important role in screening for BTT even in the presence of ID and helped identify those patients who required further laboratory evaluation.

    Very Low Frequency (VLF) measurement has been done at Pagerkandang Volcanic, Dieng Volcanic Complex (DVC) to examine the possible existence of conductive zones that related with geothermal manifestation. VLF – EM survey used tilt mode with T-VLF BRGM Iris Instrument operated with two frequencies, they are 22200 Hz from Japan (JJI) and 19800 Hz from Australia (NWC). There are five lines with distance between lines is 50 m, and distance between measure points is 20 m. The parameters measured from VLF method are tilt angle (%) and elliptisity (%). Data processed by tilt angle value with fraser and Karous – Hjelt filter used WinVLF program. Karous – Hjelt filter resulted current density contour to estimate lateral location from conductive and resistive zones. The conductive zone is interpreted as the area which have high current density value. This area located at eastern dan western of Pagerkandang Volcanic. The conductive zone related to geothermal manifestation as like as fumarol that appeared because presenced of normal fault. Whereas the resistive zone is interpreted as the area which have low current density value. This area spread almost in the middle of the Pagerkandang Volcanic. The resistive zone was caused by the high weathering in claystone.

    Full Text Available Desde hace mucho fueron destacadas las contribuciones de Foucault al campo de estudios de la infancia. Con todo, se propendió a ignorar una discusión potente: el establecimiento, en el centro de las políticas de protección de los derechos de los niños, de la indudabilidad de las necesidades infantiles. Sin embargo la categoría de necesidad no haya sido directamente trabajada por Foucault, su conceptualización de poder constituyendo de modo capilar conjuntos de dominios y rituales de verdad así como resistencia; su definición de prácticas discursivas productoras tanto de sujetos como de retóricas, y su concepción de tecnologías de gobierno, que reúnen formas de conocimiento y el locus familiar como el sitio privilegiado de regulación poblacional, han sido retomadas por Nancy Fraser y Nicholas Rose para problematizar el lugar del discurso de necesidades y el discurso psi en las políticas sociales en el capitalismo tardío. A partir de ello, exploraremos la potencia de dicha retórica y sus modos específicos de articulación con el discurso de los derechos de los niños.

  1. Inclusion and Participation: Working with the Tensions

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Democracy is crucially about inclusion: a theory of democracy must account for who is to be included in the democratic process, how, and on what terms. Inclusion, if conceived democratically, is fraught with tensions. This article identifies three such tensions, arising respectively in: (i the inauguration of the democratic public; (ii enabling equal participation; and (iii the relationship between instrumental and non-instrumental accounts of democracy’s value. In each case, I argue, rather than seeking somehow to dissolve or avoid such tensions, theories of democracy should allow us to live with their implications reflexively: to work with them. Such tensions are counter-democratic to the extent that they derail what Nancy Fraser calls “participatory parity,” under which citizens count as “full partners in social interaction.” But the extent to which they do this is not itself dependent on points of paradox in the very idea of inclusion. Such parity relies on complex factors, social and economic, which democratic institutions and procedures will not by themselves address. To achieve full democratic inclusion we must already have addressed such factors; no account of democracy itself, however finely-tuned, will do this.

  3. Educational investment towards the ideal future: South Africa�s strategic choices

    2017-01-01

    Full Text Available Although there has been rapid expansion of higher education around the globe, such expansion has not resulted in a more equitable system. Drawing on the work of Nancy Fraser, equity in higher education is conceptualised as ‘parity of participation’ and includes both equity of access and outcomes. The tensions between expansion and equity are illustrated by comparing South Africa’s equity challenges with those of Brazil and the USA. Focusing on South Africa’s critical choices, four scenarios or possible futures are provided to illustrate some of the trade-offs and strategic choices. The main argument is that if South Africa’s higher education system continues to expand without a concomitant investment in the effectiveness of teaching and learning, it will not achieve the policy goals of equity of access and outcomes. Furthermore the investment needs to be strategically targeted to interventions that can serve as systemic levers of change for reducing drop-out rates and improving graduation rates. To this end, over the next decade the state needs to prioritise an investment in an undergraduate curriculum more ‘fit for purpose’. The investment needs to be in curriculum reform that normalises different levels of foundational provision, identifies and removes curriculum obstacles that delay or impede graduation, and provides opportunities for ‘breadth’ for all students, not only those who come from privileged backgrounds.

Em um contexto de intensificação das desigualdades educacionais, são revisadas, conceitualmente, algumas das principais obras sobre a temática da justiça curricular, em circulação no Brasil, dimensionando-as na interface de duas racionalidades predominantes, quais sejam: a redistribuição e o reconhecimento. Inspirado nos escritos políticos de Nancy Fraser, este artigo defenderá como aspecto central para o processo de seleção dos conhecimentos escolares uma forma de justiça curricular centrada nas dimensões da redistribuição, do reconhecimento e da representação. De acordo com o estudo desenvolvido, o conceito de justiça curricular, em sua potencialidade conceitual, pode ser um instrumento coletivo que nos permita promover a defesa da justiça escolar e da qualidade social da educação.

    Full Text Available DOI DOI: http://dx.doi.org/10.5007/2175-7984.2016v15n34p110 During the last decades the field of social theory has seen the significant increase in the number of reflections on globalization and cosmopolitanism. Among the many efforts in this direction, the work of authors associated with critical theory, such as Jürgen Habermas, Nancy Fraser, Seyla Benhabib and Craig Calhoun, stand out. This article aims to analyze how these thinkers have approached these issues, showing how their recent work, despite differences, bear resemblances in that they seek to understand dialectically, in light of critical theory, the processes of globalization and intensifying cosmopolitanism in recent years. We intend to demonstrate that their reflections on these themes contribute to a critical perspective on cosmopolitanism and globalization, yet without leading to a rejection of a universal, democratic and emancipatory project.

Há, neste sentido, um "distanciamento" da teórica norte-americana em relação às agendas mais recentes do feminismo global (e em especial dos feminismos do Sul e uma reflexão excessivamente baseada em um "olhar desde o ocidente". É a partir dessa constatação que recupero a crítica aos estudos de matriz anglo-saxã, a partir da contribuição de C. T. Mohanty. Ao final, proponho a experiência de uma "quarta onda" dos movimentos e estudos feministas no Brasil e na América Latina, apontando para circuitos de difusão feminista operados a partir de distintas correntes horizontais de feminismos - negro, acadêmico, lésbico, masculino etc.

    Full Text Available http://dx.doi.org/10.5007/2175-7984.2017v16n35p242 The politics of identity and the idea of recognition have become dominant issues in contemporary political theory. Recognition, as a concept, means that an individual or a social group claims the right to have their identity recognized, directly or throw the mediation of set of institutions. The theories that have evaluated these questions address both important theoretical issues and central political subjects, as the definition of minority rights, national self-determination claims or the challenges posed of our increasingly multicultural societies. The main objective of this paper is to discuss the central arguments presents by Charles Taylor, Axel Honneth and Nancy Fraser emphasizing the discussion around the relationship between recognition and redistribution. A more specific purpose is to analyze the relation between the question of injustice based on the demand of identity and the problem of economic inequality. Finally, we try to understand some of the theoretical and political implications of the idea of difference and the recognition theory in a broader conceptual perspective.

    Celi Regina Jardim Pinto

    Full Text Available Resumo Este artigo tem como objetivo discutir as teorias do reconhecimento como instrumental para a análise das manifestações de rua ocorridas no Brasil em junho de 2013. Examina três autores: Nancy Fraser, Axel Honneth e Judith Butler, descrevendo os pontos centrais da teoria do reconhecimento de cada um deles, para assim apontar as possibilidades e os limites de sua aplicação no estudo em pauta. A hipótese que norteia o artigo é a seguinte: nas manifestações de rua de 2013, a ausência de sujeitos coletivos organizados caracterizou uma condição de dispersão e fragmentação, resultando em uma demanda por reconhecimento antipolítica e individualizada. Tendo em vista esse cenário, chegou-se à conclusão de que as teses de Judith Butler sobre reconhecimento foram as que se mostraram mais apropriadas à análise dos eventos.

    The role of British Columbia Hydro in addressing regional economic development issues in British Columbia is discussed. At Stave Falls in the Fraser Valley, a project is under way to upgrade a 75-year-old hydroelectric facility to utilize its potential more fully without having to flood more land. The project will eventually cost $50-100 million and will also generate local employment. In the Kootenay region, the utility has established a regional office in Castlegar and is organizing a symposium to examine historical grievances such as reservoir levels, taxation, and electric system operation. A new formula has been announced with regards to independent power producers and it is intended to proceed with wood-waste power generation and gas-fired cogeneration projects if they make economic and environmental sense. Energy conservation activities are continually being implemented through the utility's Power Smart program, and tourism-related concerns caused by low reservoir levels in the Kootenay region are also being addressed

    Full Text Available Male-dominated and sex segregated elite professional and amateur sport1 in North America constitutes a "sport nexus" (Burstyn, 1999; Heywood & Dworkin, 2003 that combines economic and cultural influence to reinforce and perpetuate gender injustice. The sport nexus is an androcentric sex-segregated commercially powerful set of institutions that is highly visible and at the same time almost completely taken for granted to the extent that its anti-democratic impetus goes virtually unnoticed. The sport nexus’s hegemonic role in defining sporting norms (Coakley & Donnelly, 2004 means that its role in shaping lower level amateur and recreational sporting institutions and cultures is highly significant. Fraser (2007 defines gender justice, and hence democracy, in terms of "participatory parity," that is, material and cultural equality for women. The sport nexus itself is characterized by highly gendered occupational segregation (Coventry, 2004. It further contributes to gender injustice, homophobia and transphobia by promoting the ideology of the two sex system (Fausto-Sterling, 2000 and gendering citizenship as fundamentally male (Burstyn, 1999. Feminist strategies for sport reformation attempt to reduce or eradicate the role of the sport nexus in legitimating and perpetuating gender injustice. In this article I consider the potential of these strategies and conclude with a set of recommendations for transforming organized sport at both elite and recreational levels.

    Biogeochemical responses and ecosystem recovery from bark beetle outbreaks are influenced by pre-disturbance forest structure and composition and catchment conditions. Over the past decade, the mountain pine bark beetle (Dendroctonus ponderosae) has killed mature lodgepole pine (Pinus contorta) trees at the Fraser Experimental Forest and throughout the Colorado Rockies. Here we compare stream nitrogen (N) concentrations during the outbreak with data from the previous two decades in four research catchments with distinct forest management history, stand age structure and watershed characteristics. In two old growth forest catchments, stream nitrate concentrations were significantly higher during the infestation in the snowmelt and base flow seasons. The beetle infestation elevated nitrate export 43 and 74% in these two catchments though the amounts of N released in streamwater (0.04 and 0.15 kg N ha-1) were beetle infestation in two catchments comprised of a mixture of second-growth (30-60 year old) and old-growth (250-350 year old) forest stands where the density of residual live trees was higher on average. Mortality of overstory trees from bark beetles has stimulated the growth of understory and overstory trees with likely consequences for nutrient demand and retention in recovering forests.

    2012-04-01

    We present a review of different micropatterning technologies for flexible elastomeric functional nanocomposites with a particular emphasis on mold material and processes for production of large size substrates. The functional polymers include electrically conducting and magnetic materials developed at the Micro-instrumentation Laboratory at Simon Fraser University, Canada. We present a chart that compares many of these different conductive and magnetic functional nanocomposites and their measured characteristics. Furthermore, we have previously reported hybrid processes for nanocomposite polymers micromolded against SU-8 photoepoxy masters. However, SU-8 is typically limited to substrate sizes that are compatible with microelectronics processing as a microelectronics uv-patterning step is typically involved, and de-molding problems are observed. Recently, we have developed new processes that address the problems faced with SU-8 molds. These new technologies for micropatterning nanocomposites involve new substrate materials. A low cost Poly(methyl methacrylate) (PMMA) microfabrication technology has been developed, which involves fabrication of micromold via either CO2 laser ablation or deep UV. We have previously reported this large-scale patterning technique using laser ablation. Finally, we compare the two processes for PMMA producing micromolds for nanocomposites.

    This presentation outlined a research program designed to characterize future weather scenarios for BC Hydro. The program evaluated the impacts of climatic change on water resources managed by the utility for hydroelectric power generation by deriving climatic change-adjusted meteorologic and hydrologic sequences designed for use in system operations and planning studies. The effects of climate change on generation, inflow, and future reservoir levels were evaluated. Modified weather records were used to simulate alternative runoff and load patterns. The climate-adjusted sequences were validated using historical meteorological and hydrological records. The study examined the influence of precipitation, loads, and future electricity prices on BC Hydro system operations. The program will develop diagnostic hydrologic and climate models as well as to determine the impact of surface conditions on Fraser River hydrology. The program will be comprised of global climate model and Canadian regional climate model outputs. Results to date anticipate increases in winter temperatures, cooling of summer temperatures, and increases in precipitation for the region. Results of the program will be used in system planning studies. tabs., figs

    Full Text Available The changes in the Polish socio-economic system, initiated at the turn of 1989 and 1990, led to a systematic increase in the liberalization of economy and thereby the rise of the level of economic freedom. The aim of this paper is to examine the impact of the economic transition on the development of economic freedom in Poland. The analysis, carried out in the period 1995-2015, was conducted on the basis of the chain-linked Economic Freedom Index by the Fraser Institute and the Index of Economic Freedom of the Heritage Foundation and the Wall Street Journal. The analysis indicates that: (1 Poland cannot be considered as a country that is fully free economically, but the transition of its economic system has resulted in a rapid growth of economic freedom. (2 The impact of transition varies for different areas (sub-indices of the economy. (3 The European economic integration stimulated the increase of EFI, but the economic crisis did not decrease the level of economic freedom.

The potential for energy generation from biogas through anaerobic digestion is approximately 30 MW. On-farm manure-based systems represent the most likely scenario for the development of anaerobic digestion in British Columbia in the near future. Off-farm food processing wastes may be an alternative option to large centralized industrial complexes. Odour control, pathogen reduction, improved water quality, reduced greenhouse gas emissions and reduced landfill usage are among the environmental benefits of anaerobic digestion. The economical benefits include power and heat generation, biogas upgrading, and further processing of the residues to produce compost or animal bedding. This paper described a newly developed anaerobic digestion (AD) calculator that helps users regarding their investment decision in AD facilities. The calculator classifies various technology options into several major types of AD systems. It also constructs kinetic and economic models for these systems and provides a fair estimation on biogas yield, digester volume, capital cost and annual income. The calculator takes into consideration factors such as the degradability of wastes with different compositions and different operating parameters.

  3. Remembering Tomorrow: Wagon Roads, Identity and the Decolonization of a First Nations Landscape

    Full Text Available Roads embody the experiences of those who construct, use and maintain them through time. Using a biographical approach I explore how memory and identity are entangled in the material remains of a wagon road in southwestern British Columbia, Canada. First constructed by the Royal Engineers in 1859 to enable miners to reach the Fraser River goldfields, the importance of this road transcends its colonial origins. Entwined in different webs of meaning, the material remains of the wagon road continue to play a role in the lives of people today. In this article I investigate the significance of this wagon road to the indigenous Stl’atl’imx (pronounced Stat-lee-um people of the lower Lillooet River Valley who aim to preserve it as a part of decolonizing and reclaiming their traditional territory and identity. I also look at the road’s importance to a group of Grade 10 students who experience it as part of a high school excursion that teaches outdoor survival skills alongside lessons about British Columbia’s historic past. While these two groups have different experiences of the colonial encounter, for each their understanding of the road goes beyond its physical form to its ‘place’ in understanding their own identity.

  5. Accounting for biases in riboprofiling data indicates a major role for proline in stalling translation.

    Artieri, Carlo G; Fraser, Hunter B

    2014-12-01

    The recent advent of ribosome profiling-sequencing of short ribosome-bound fragments of mRNA-has offered an unprecedented opportunity to interrogate the sequence features responsible for modulating translational rates. Nevertheless, numerous analyses of the first riboprofiling data set have produced equivocal and often incompatible results. Here we analyze three independent yeast riboprofiling data sets, including two with much higher coverage than previously available, and find that all three show substantial technical sequence biases that confound interpretations of ribosomal occupancy. After accounting for these biases, we find no effect of previously implicated factors on ribosomal pausing. Rather, we find that incorporation of proline, whose unique side-chain stalls peptide synthesis in vitro, also slows the ribosome in vivo. We also reanalyze a method that implicated positively charged amino acids as the major determinant of ribosomal stalling and demonstrate that it produces false signals of stalling in low-coverage data. Our results suggest that any analysis of riboprofiling data should account for sequencing biases and sparse coverage. To this end, we establish a robust methodology that enables analysis of ribosome profiling data without prior assumptions regarding which positions spanned by the ribosome cause stalling. © 2014 Artieri and Fraser; Published by Cold Spring Harbor Laboratory Press.

    Stephen Hawking's inaugural lecture as Lucasian Professor of Mathematics at Cambridge University in 1980 caused quite a stir. Its title - 'Is the end in sight for theoretical physics?' - raised the prospect of a unified 'theory of everything'. Hawking suggested that there was a good chance of resolving the remaining inconsistencies between the two big 'theories of something' - quantum mechanics and general relativity - before the turn of the century. My first impression on reading The New Physics for the Twenty-First Century, a collection of essays edited by science journalist Gordon Fraser, is that a theory of everything may still be attainable by the turn of the century. However, there is now 20 times more of everything in the universe than there was in the past century, 95% of which no-one has ever actually seen, or had even heard of until a few years ago - as summarized in articles by Wendy Freedman, Edward Kolb and Ronald Adler. Despite this, Michael Green describes amazing developments in string theory that could tie everything together, if one could just figure out which, if any, of the apparently infinite varieties of string theory applies to our world, and why.

    Medical students carry a large academic load which could potentially contribute to poor sleep quality above and beyond that already experienced by modern society. In this global literature review of the medical students' sleep experience, we find that poor sleep is not only common among medical students, but its prevalence is also higher than in non-medical students and the general population. Several factors including medical students' attitudes, knowledge of sleep, and academic demands have been identified as causative factors, but other potential mechanisms are incompletely understood. A better understanding about the etiology of sleep problems in medical trainees is essential if we hope to improve the overall quality of medical students' lives, including their academic performance. Sleep self-awareness and general knowledge appear insufficient in many studied cohorts, so increasing education for students might be one beneficial intervention. We conclude that there is ample evidence for a high prevalence of the problem, and research in this area should now expand towards initiatives to improve general sleep education for medical students, identify students at risk, and target them with programs to improve sleep.

    2003-01-01

    Analysis of the TOMS minimum reflectivity data for 380 nm channel (R380) show regions of high reflectivity values (approx. 7 to 8%) over Sargasso Sea in the Northern Atlantic, anti-cyclonic region in the Southern Atlantic, and a large part of the ocean in the Southern Pacific, and low values (5 approx. 6 %) over the rest of the open ocean. Through radiative transfer simulations we show that these features are highly correlated with the distribution of chlorophyll in the ocean. Theoretical minimum reflectivity values derived with the help of CZCS chlorophyll concentration data as input into a vector ocean-atmosphere radiative transfer code developed by Ahmad and Fraser show very good agreement with TOMS minimum reflectivity data for the winter season of year 1980. For the summer season of year 1980, good qualitative agreement is observed in the equatorial and northern hemisphere but not as good in the southern hemisphere. Also, for cloud-free conditions, we find a very strong correlation between R340 minus R380 values and the chlorophyll concentration in the ocean. Results on the possible effects of absorbing and non-absorbing aerosols on the TOMS minimum reflectivity will also be presented. The results also imply that ocean color will affect the aerosol retrieval over oceans unless corrected.

    2018-03-01

    Full Text Available Unionised work environments within large seaports attract transnational organised crime, and this presents a challenge for law enforcement agencies. If media stories are true, a motorcycle club called the Hells Angels has established a presence on Vancouver area waterfronts since coming to the province of British Columbia. Associations between longshore union locals, club members, and known contacts are implied and presented as evidence of participation in criminality. This paper revisits the perception that criminal activity is endemic in the Port of Vancouver because of a lack of policing, adequate resources, and indifference from port authorities, employer bodies, as well as union leadership. In an era of heightened concerns about public safety and national security, federal and provincial governments understand the importance of seaports, especially in Vancouver and up the Fraser River. These port facilities are important to international trade that flows through them as part of Asia-Pacific Gateway and Corridor initiatives. Therefore, targeted investments, close coordination amongst government departments and agencies, and engagement with waterfront stakeholders promote secure places hard for organised criminals to operate freely.

    2017-12-01

    The Low-Back Outcome Scale (LBOS) of Greenough and Fraser and the Oswestry disability index (ODI) were compared to the patient satisfaction index (PSI) in lumbar disc herniation (LDH) surgery. A total of 134 patients who underwent discectomy were followed through assessment of pre- and post-surgical satisfaction by the PSI, the LBOS, and the ODI. The LBOS were rated as satisfied if the outcomes were excellent or good and as dissatisfied if fair and poor. Considering the ODI, clinically satisfied was defined as a 13-point improvement from the baseline ODI scores. Phi (Φ) correlation analysis was used to study the correlation among the PSI, the LBOS and the ODI scores as proxy for patients' satisfaction. Mean age of patients was 48.9 years. Significant improvement from the pre- to post-operative ODI scores was observed. Post-surgical satisfaction based on the PSI, the ODI, and the LBOS were 70.9%, 76.8%, and 81.3%, respectively. Regarding patient satisfaction, there were weak associations between LBOS vs. PSI and ODI vs. PSI (Φ=-0.054, P=0.533) and (Φ=-0.129, P=0.136), respectively. Our study showed that the ODI and the LBOS were not reflective of patients' satisfaction after discectomy.

    Full Text Available A potential link between electromagnetic emission (EME and seismic activity (SA has been the subject of scientific speculations for a long time. EME versus SA relations obtained during the 2008 earthquake swarm which occurred in West Bohemia are presented. First, a brief characterisation of the seismic region and then the EME recording method and data analysis will be described. No simple direct link between EME and SA intensity was observed, nevertheless a deeper statistical analysis indicates: (i slight increase of EME activity in the time interval 60 to 30 min before a seismic event with prevalent periods about 10 min, (ii some gap in EME activity approximately 2 h after the event, and (iii again a flat maximum about 4 h after the seismic events. These results qualitatively correspond with the observations from other seismically active regions (Fraser-Smith et al., 1990. The global decrease of EME activity correlating with the swarm activity decay was also observed. Due to the incomplete EME data and short observation time, these results are limited in reliability and are indicative only.

    Snow water storage in land is a critical parameter of the water cycle. In this study, we develop methods for estimating reflectance from bistatic scattering of digital communication Signals of Opportunity (SoOp) across the available microwave spectrum from VHF to Ka band and show results from proof-of-concept experiments at the Fraser Experimental Forest, Colorado to acquire measurements to relate the SoOp phase and reflectivity to a snow-covered soil surface. The forward modeling of this scenario will be presented and multiple sensitivities were conducted. Available SoOp receiver data along with a network of in situ sensor measurements collected since January 2016 will be used to validate theoretical modeling results. In the winter season of 2016 and 2017, we conducted a field experiment using VHF/UHF-band illuminating sources to detect SWE and surface reflectivity. The amplitude of the reflectivity showed sensitivity to the wetness of snow pack and ground reflectivity while the phase showed sensitivity to SWE. This use of this concept can be helpful to measure the snow water storage in land globally.

  14. How do potential knowledge users evaluate new claims about a contested resource? Problems of power and politics in knowledge exchange and mobilization.

    2016-12-15

    This article examines how potential users of scientific and local/traditional/experiential knowledge evaluate new claims to knowing, using 67 interviews with government employees and non-governmental stakeholders involved in co-managing salmon fisheries in Canada's Fraser River. Research has consistently shown that there are major obstacles to moving new knowledge into policy, management, and public domains. New concepts such as Knowledge Exchange (KE) and Knowledge Mobilization (KMb) are being used to investigate these obstacles, but the processes by which potential users evaluate (sometimes competing) knowledge claims remain poorly understood. We use concepts from the sociology of science and find that potential users evaluate new knowledge claims based on three broad criteria: (1) the perceived merits of the claim, (2) perceptions of the character and motivation of the claimant, and (3) considerations of the social and political context of the claim. However, government employees and stakeholders have different interpretations of these criteria, leading to different knowledge preferences and normative expectations of scientists and other claimants. We draw both theoretical and practical lessons from these findings. With respect to theory, we argue that the sociology of science provides valuable insights into the political dimensions of knowledge and should be explicitly incorporated into KE/KMb research. With respect to practice, our findings underline the need for scientists and other claimants to make conscious decisions about whose expectations they hope to meet in their communications and engagement activities.

  16. Curation Pedagogy for Media Studies: (Further Towards the Inexpert

    2012-12-01

    Full Text Available An educational ‘model’ for participatory learning and media literacy in the contemporary context of digitally mediated lifeworlds is emerging (Jenkins, 2010; Gauntlett, 2011; Fraser and Wardle, 2011. The critical problem, we argue, for its ‘adequacy’ is the privilege granted to curriculum content and skills over pedagogy. Elsewhere, we offered a ‘pedagogy of the inexpert’ as such a model for textconscious disciplines such as, but not restricted to, Media Studies. This strategy removes ‘the media’ from our gaze and looks awry to develop new ways of working with students – to ‘show and tell’ textual agency and more reflexive deconstruction of what it is to read and make media, and to ‘be’ in mediation. In this article, we develop this approach further towards a model of ‘curation’. Understood in this way, students ‘show’ media literacy in new spaces – not by recourse to skills, competences or analytical unmasking of the properties of a (contained text, but by exhibiting, by curating a moment in time of textual meaningmaking and meaning-taking, but with a mindfulness – a critical acceptance of such an attempt to hold and curate the flow of meaning as an artifice.

  17. Impact of the initiatives of the CCME [Canadian Council of Ministers of the Environment] management plan with regard to reduction of NOx and VOC [volatile organic compounds] in the Canadian petroleum refining and distribution industry

    1992-01-01

    The Canadian petroleum refining and distribution industry produces 98,300 tonnes/y of emissions of volatile organic compounds (VOC), or 5.5% of the national inventory. The Canadian Council of Ministers of the Environment (CCME) has formulated plans for controlling emissions of nitrogen oxides (NOx) and VOC, and the Canadian petroleum industry is in broad agreement with the CCME proposals that control measures must be taken to reduce ozone levels in regions with an ozone problem (notably the Windsor-Quebec City corridor and the Fraser Valley) by taking appropriate measures to reduce emissions of ozone precursors NOx and VOC. Three types of NOx reduction initiatives are outlined: increasing energy efficiency, reducing NOx from furnaces and boilers, and modernization of certain refinery processes. Initiatives for reducing VOC include limiting the volatility of petroleum fuels, control of fugitive vapor emissions from storage tanks, recovery of such vapors from service stations and fuel transfer depots, and control of fugitive hydrocarbon emissions from refineries. The economic impacts of these initiatives are evaluated, showing important variations in terms of benefits and efficiency for the options considered. 9 refs., 2 figs., 2 tabs

    Full Text Available Photogrammetric mapping using Commercial of the Shelf (COTS cameras is becoming more popular. Their popularity is augmented by the increasing use of Unmanned Aerial Vehicles (UAV as a platform for mapping. The mapping precision of these methods can be increased by using a calibrated camera. The USGS/EROS has developed an inexpensive, easy to use method, particularly for calibrating short focal length cameras. The method builds on a self-calibration procedure developed for the USGS EROS Data Center by Pictometry (and augmented by Dr. C.S Fraser, that uses a series of coded targets. These coded targets form different patterns that are imaged from nine different locations with differing camera orientations. A free network solution using collinearity equations is used to determine the calibration parameters. For the smaller focal length COTS cameras, the USGS has developed a procedure that uses a small prototype box that contains these coded targets. The design of the box is discussed, along with best practices for calibration procedure. Results of calibration parameters obtained using the box are compared with the parameters obtained using more established standard procedures.

  19. The Sport Nexus and Gender Injustice

    Full Text Available Male-dominated and sex segregated elite professional and amateur sport1 in North America constitutes a "sport nexus" (Burstyn, 1999; Heywood & Dworkin, 2003 that combines economic and cultural influence to reinforce and perpetuate gender injustice. The sport nexus is an androcentric sex-segregated commercially powerful set of institutions that is highly visible and at the same time almost completely taken for granted to the extent that its anti-democratic impetus goes virtually unnoticed. The sport nexus’s hegemonic role in defining sporting norms (Coakley & Donnelly, 2004 means that its role in shaping lower level amateur and recreational sporting institutions and cultures is highly significant. Fraser (2007 defines gender justice, and hence democracy, in terms of "participatory parity," that is, material and cultural equality for women. The sport nexus itself is characterized by highly gendered occupational segregation (Coventry, 2004. It further contributes to gender injustice, homophobia and transphobia by promoting the ideology of the two sex system (Fausto-Sterling, 2000 and gendering citizenship as fundamentally male (Burstyn, 1999. Feminist strategies for sport reformation attempt to reduce or eradicate the role of the sport nexus in legitimating and perpetuating gender injustice. In this article I consider the potential of these strategies and conclude with a set of recommendations for transforming organized sport at both elite and recreational levels.

    2008-10-01

    The Silicon Highly-segmented Array for Reactions and Coulex (SHARC) is a multi-purpose array for charged-particle detection. The array is designed to have high spatial resolution, a large solid angle coverage, and particle identification of the measured reaction products. This combination offers unique capabilities when integrated with the TIGRESS gamma-ray detectors and the post-accelerated beams at the ISAC-II facility at TRIUMF, Canada. Two major research programs will gain significantly from the utilization of SHARC: Reaction studies with particular emphasis on transfer reactions used to indirectly probe nuclear reaction rates important for explosive stellar scenarios as well as nuclear structure studies in which Coulomb excitation will play an important role. The project is funded by the UK-STFC and is lead from the University of York with collaborators from the UK Universities of Birmingham, Liverpool, Manchester, and Surrey, and Daresbury Laboratory; Colorado School of Mines and Louisiana State University of the USA; and from Canada: TRIUMF as well as McMaster, Saint Mary's, and Simon Fraser Universities.

    2016-02-01

    Three-day forecasts of ocean currents, temperature and salinity along the Oregon and Washington coasts are produced daily by a numerical ROMS-based ocean circulation model. NAM is used to derive atmospheric forcing for the model. Fresh water discharge from Columbia River, Fraser River, and small rivers in Puget Sound are included. The forecast is constrained by open boundary conditions derived from the global Navy HYCOM model and once in 3 days assimilation of recent data, including HF radar surface currents, sea surface temperature from the GOES satellite, and SSH from several satellite altimetry missions. 4-dimensional variational data assimilation is implemented in 3-day time windows using the tangent linear and adjoint codes developed at OSU. The system is semi-autonomous - all the data, including NAM and HYCOM fields are automatically updated, and daily operational forecast is automatically initiated. The pre-assimilation data quality control and post-assimilation forecast quality control require the operator's involvement. The daily forecast and 60 days of hindcast fields are available for public on opendap. As part of the system model validation plots to various satellites and SEAGLIDER are also automatically updated and available on the web (http://ingria.coas.oregonstate.edu/rtdavow/). Lessons learned in this pilot real-time coastal ocean forecasting project help develop and test metrics for forecast skill assessment for the West Coast Operational Forecast System (WCOFS), currently at testing and development phase at the National Oceanic and Atmospheric Administration (NOAA).

  2. Cognitive Capitalism: Economic Freedom Moderates the Effects of Intellectual and Average Classes on Economic Productivity.

    Cognitive ability stimulates economic productivity. However, the effects of cognitive ability may be stronger in free and open economies, where competition rewards merit and achievement. To test this hypothesis, ability levels of intellectual classes (top 5%) and average classes (country averages) were estimated using international student assessments (Programme for International Student Assessment; Trends in International Mathematics and Science Study; and Progress in International Reading Literacy Study) (N = 99 countries). The ability levels were correlated with indicators of economic freedom (Fraser Institute), scientific achievement (patent rates), innovation (Global Innovation Index), competitiveness (Global Competitiveness Index), and wealth (gross domestic product). Ability levels of intellectual and average classes strongly predicted all economic criteria. In addition, economic freedom moderated the effects of cognitive ability (for both classes), with stronger effects at higher levels of freedom. Effects were particularly robust for scientific achievements when the full range of freedom was analyzed. The results support cognitive capitalism theory: cognitive ability stimulates economic productivity, and its effects are enhanced by economic freedom. © The Author(s) 2016.

    Fusarium is a cosmopolitan and highly diversified genus of saprophytic, phytopathogenic and toxigenic fungi. However, the existence and diversity of a few species of Fusarium are restricted to a certain area or climatic condition. The present study was conducted to determine the occurrence and diversity of Fusarium species in tropical highland areas in Malaysia and to compare with those in temperate and subtropical regions. A series of sampling was carried out in 2005 to 2009 at several tropical highland areas in Malaysia that is: Cameron Highlands, Fraser Hills and Genting Highlands in Pahang; Penang Hill in Penang; Gunung Jerai in Kedah; Kundasang and Kinabalu Park in Sabah; Kubah National Park and Begunan Hill in Sarawak. Sampling was done randomly from various hosts and substrates. Isolation of Fusarium isolates was done by using pentachloronitrobenzene (PCNB) agar and 1449 isolates of Fusarium were successfully recovered. Based on morphological characteristics, 20 species of Fusarium were identified. The most prevalent species occurring on the highlands areas was F. solani (66.1%) followed by F. graminearum (8.5%), F. oxysporum (7.8%), F. semitectum (5.7%), F. subglutinans (3.5%) and F. proliferatum (3.4%). Other Fusarium species, namely F. avenaceum, F. camptoceras, F. chlamydosporum, F. compactum, F. crookwellense, F. culmorum, F. decemcellulare, F. equiseti, F. nygamai, F. poae, F. proliferatum, F. sacchari, F. sporotrichioides, F. sterilihyphosum and F. verticillioides accounted for 1% recoveries. The present study was the first report on the occurrences of Fusarium species on highland areas in Malaysia.

    2015-02-01

    When studying the phase changes process in a rolled AA8011 alloy using DSC, we find that the peaks associated with phase precipitation under this microstructural condition are different from those obtained in homogenized microstructures. The differences observed are attributable, first, to the recovery process occurring at temperatures below 423 K (150 °C), which interacts with the precipitation of Si-rich precipitates or with Guinier-Preston zones both coexistent in that temperature range; and second, to the recrystallization above 473 K (200 °C), which coexists with precipitation of the α-AlFeSi phase. In this work, the precipitation and recovery-recrystallization kinetics are experimentally obtained and deconvoluted in peaks characteristic for each of the mechanisms involved; i.e., precipitation of GP zones, recovery, precipitation of α phase, and recrystallization. The deconvolution is achieved using functions of Gauss, Weibull, and Fraser-Suzuki; and the characterization of each reaction deconvoluted is realized through both Jhonson-Melh-Avrami-Erofeev-Kolmorokov kinetic models and Sesták-Berggren combined kinetic model. The kinetic study evinces that in addition to the expected reactions, other reactions, necessary for good experimental adjustment, appear. An isoconversional study is undertaken to numerically evaluate the kinetic triplet of every process.

    The Strait of Georgia at the west coast of Canada is an enclosed coastal strait, about 250km long and 25 to 50 km wide, with great socio-economic importance. Regular freighter traffic, ferry services, commercial and sport fisheries, and recreational boating, makes the area one of the busiest marine areas in the world. Waves in SoG are generally small, with the median value of the significant wave height Hs=0.3m. However, strong outflows off the mountainous terrain can generate significant wave heights Hs > 2.5m, with high spatial and temporal variability. In addition, strong tidal currents and the Fraser River outflow generate localized regions of steep and breaking waves that are of particular concern. We have implemented the Wavewatch III model at 500m-resolution, forced by Environment Canada's high resolution atmospheric model winds and currents from the UBC NEMO implementation of the Salish Sea. The final output combines GIS layers of the predicted wave field (Hs, dominant wave length and direction), the modeled wind field and currents, observed currents from a set of CODAR systems, and a sea state index that highlights regions of potentially steep and dangerous waves.

    British Columbia Hydro supplies electric energy to 93% of the province's population through an integrated electric system. Of the electricity supplied, 95% is generated at 29 hydroelectric plants, with the remainder coming from thermal plants burning fossil fuels. BC Hydro's high voltage transmission and distribution network consists of 17,600 km of lines 60 kV and above and 51,400 km of lines below 60 kV. A description of system operations begins with the principles of hydroelectric generation, with a brief note on thermal generation for peaking or short-term energy production. Non-power operations measures designed to minimize environmental impacts and enhance social benefits are also outlined along with electricity trade with other provinces and the USA. Planning of long- and short-term system operations is also reviewed. An analysis of system components is presented for the Peace, Columbia, Lower Mainland/Coastal/Fraser, and Vancouver Island regions. Finally, information is given on the 29 hydroelectric and 3 thermal plants, including drainage basin, reservoir description and map, inflow, capacity, turbine type, storage, operating constraints, and average energy capability. 51 figs

    Full Text Available Biotelemetry has become a popular tool accepted by the scientific community as a reliable approach for studying wild fish. However, stakeholder perspectives on scientific techniques and the information they generate are not uniformly positive. Aboriginal groups in particular may have opposition or apprehension to telemetry as a research tool. To that end, we conducted a river-bank survey of 111 aboriginal First Nations fishers that target adult Pacific salmon in the lower Fraser River, British Columbia, Canada. The majority of respondents had heard of telemetry, but few had knowledge of its function. Most responses regarding the use of telemetry in fisheries science were positive. The few negative perspectives were primarily concerned about the effects of tagging procedures whereas positive perspectives arose because telemetry was perceived to generate information on migration patterns and survival. Over half of the respondents would trust data arising from telemetry studies, but some had conditions related to the group conducting the research and their experience with fish handling. Several respondents noted the need for additional consultation and outreach with aboriginal communities (especially fishers to better inform them of study questions and techniques which, in the case of telemetry studies, could promote better participation in tag return programs and uptake of knowledge emanating from use of telemetry.

    Supervisor's supporting comments. I am pleased to recommend Sadagopan Krishnan for the Bioanalysis Young Investigator award. Sadagopan is a bright, creative and highly-motivated young bioanalytical chemist. His theses in our laboratory involved the development of electrochemiluminescent arrays for chemical toxicity screening utilizing cytochrome P450 metalloenzymes. He was senior author of a paper in Analytical Chemistry on this that was featured on the cover. He also investigated fundamental properties of human metabolic cytochrome P450s - research was carried out at his own initiative, and explains for the first time the role of iron spin state on enzyme electron transfer rates. He then developed thin films that mimic the natural cytochrome P450 redox cycle for the first time. He worked with several other group members to develop a superparamagnetic labeling scheme for immunosensing of proteins by surface plasmon resonance at unprecedented low levels, down to 10 fg/ml. Sadagopan has also demonstrated strong leadership skills. After his PhD, Sadagopan joined the group of Fraser Armstrong at Oxford University, UK, as a postdoctoral fellow. He is currently expanding his research horizons into the area of biofuel cells. His eventual goal is to join the faculty of a major university and build a world-class research group in bioanalytical chemistry.

  10. Reducing environmental risks in water management in British Columbia

    International Nuclear Information System (INIS)

    Brownlow, H.

    1998-01-01

    The issue of water management regarding hydroelectric generating facilities in British Columbia was discussed. BC Hydro has adopted the following three processes to address water management risks: (1) the Electric System Operating Review, (2) Water Use Plans, and (3) an Environmental Management System. The greatest concern regarding water management are the potential impacts to fish and fish habitat. More than 90 per cent of BC Hydro's installed capacity is hydroelectric, with the balance produced by natural gas and diesel. All facilities are licensed under the provincial Water Act which has been in effect for the past century and is currently way out of date. Among its inadequacies is the fact that it does not provide for the protection of fish. The B.C. Fish Protection Act suggests that effective immediately, there should be no new dams on the Fraser and other significant rivers. BC Hydro facilities impact 16 of the 2,576 streams in British Columbia that support anadromous (migrating) salmon stocks. BC Hydro has 25 dams and diversions located on these 16 rivers. It was concluded that BC Hydro's impact on fish and fish habitat, although relatively small compared to the total fish resource in the province, is significant. The technology now used by BC Hydro is claimed to have the capacity to allow for easy documentation, rapid communication and the development of a comprehensive database for use in identifying and managing the impact of the Utility's operations on the fish population. 10 refs., 12 figs

    2000-01-01

    This report is a collection of essays which, collectively, detail the current situation of energy and climate policy in British Columbia, taking account of the full consequences of addiction to fossil fuels and the automobile. The report examines the forces at work responsible for the current situation, namely population growth, urban sprawl, low density communities in the Lower Fraser Valley, southern Vancouver Island and other parts of the province. The growing pressure on the development of agricultural land, congestion on highways and in cities, the increase in air pollution, land alienation, longer commutes to and from work, increased demand for electricity and natural gas, construction of new power plants, pipelines and gas processing facilities are just further examples of the same trend, culminating in dramatic growth in greenhouse gas emissions. The report proposes a range of conservation and renewable options in the areas of urban land use and transportation, commercial and industrial energy reduction and oil and gas production, and provides some ideas of how these recommendations could be realized by businesses, institutions and individuals. It insists on stressing that while the challenges are formidable, they could be achieved through a combination of regulation, public investment, market mechanisms and cultural change. 163 end-notes, tabs

  12. Resilient Salmon, Resilient Fisheries for British Columbia, Canada

    Directory of Open Access Journals (Sweden)

    Michael C. Healey

    2009-06-01

    Full Text Available Salmon are inherently resilient species. However, this resiliency has been undermined in British Columbia by a century of centralized, command-and-control management focused initially on maximizing yield and, more recently, on economic efficiency. Community and cultural resiliency have also been undermined, especially by the recent emphasis on economic efficiency, which has concentrated access in the hands of a few and has disenfranchised fishery-dependent communities. Recent declines in both salmon stocks and salmon prices have revealed the systemic failure of the current management system. If salmon and their fisheries are to become viable again, radically new management policies are needed. For the salmon species, the emphasis must shift from maximizing yield to restoring resilience; for salmon fisheries, the emphasis must shift from maximizing economic efficiency to maximizing community and cultural resilience. For the species, an approach is needed that integrates harvest management, habitat management, and habitat enhancement to sustain and enhance resilience. This is best achieved by giving fishing and aboriginal communities greater responsibility and authority to manage the fisheries on which they depend. Co-management arrangements that involve cooperative ownership of major multistock resources like the Fraser River and Skeena River fisheries and community-based quota management of smaller fisheries provide ways to put species conservation much more directly in the hands of the communities most dependent on the well-being and resilience of these fisheries.

    Chatare, Vijay K.

    My research involved in two different areas, development of novel glycosylation methodology and scope in oligosaccharide synthesis. A new scaffold for antibiotic development targeting the bacterial cell wall: Total synthesis of Albocycline and its analogs to see the mechanism of action in cell wall biosynthesis. Developed novel gem-dimethyl analogs of Fraser-Reid's NPGs from 3,3-dimethyl 4-pentenol and 2,2-dimethyl 4-pentenol. These donors are stable toward acidic and basic conditions, which makes them step-efficient when compared to other glycosylating agents. The scope and reactivity of 3,3-dimethyl 4-pentenyl glycosides of glucose, mannose, galactose, and N-acetylglucosamine have been studied extensively for oligosaccharide synthesis. The donors are readily prepared from commercial starting materials and both glycosylation and hydrolysis yields are in the synthetically useful in oligosaccharide synthesis. NSMD methodology introduced a key step in albocycline synthesis, where (-)-albocycline has great biological activity against "superbug" methicillin-resistant Staphylococcus aureus (MRSA). We hypothesize that albocycline inhibits the first committed step in bacterial cell wall biosynthesis. We have successfully completed two generation syntheses of albocycline. Vinylogous aldol on the left-handed fragment, aldehyde to get selectively up alcohol at the C-8 position using Davis-Ellman sulfinylimine chemistry and then oxidation with Davis oxaziridine to access requisite stereochemistry at C-4 alcohol followed by Horner-Wadsworth-Emmons to access seco-acid. Finally, a Keck macrolactonization reaction provided access to desired (-)-Albocycline.

    2012-05-01

    Elevated alphafetoprotein (AFP) concentrations may result from a variety of clinical conditions, but their role as an important tumour marker has been well established. There may be differences in AFP values due to laboratories using different methods, even though most methods have been calibrated with the same international standard (WHO IS 72/225). Therefore it is important to know the analytical performance of the various methods in relation to the analytical requirements for AFP measurement. Annually, from January 2005 to July 2010, the results were analysed from the 65-75 laboratories that took part in the AFP survey of the External Quality Assurance programme of the Foundation Quality Control Medical Laboratories (the SKML/Binding Analysis) in the Netherlands. The Elecsys/Modular (36%) and the Immulite 2000/2500 (29%) are the methods used most. The methods show, on average, up to 15% positive and 12% negative bias, compared with the all-laboratory trimmed mean. Of the laboratories using the Immulite or the Elecsys/Modular analyser, over 70% show sufficient analytical performance to meet the Fraser criterion for method imprecision. Of the laboratories using a different method, over 50% do not meet this criterion. AFP immunoassays suffer from method bias, even though all methods have been calibrated with the same international standard. Some of the methods used show insufficient performance.

  16. Don't fence me in: managing psychological well being for elite performance horses.

    Science.gov (United States)

    Henderson, Antonia J Z

    2007-01-01

    This article posits that stereotypical behavior patterns and the overall psychological well being of today's performance horse could be substantially enhanced with care that acknowledges the relationship between domesticated horses and their forerunners. Feral horses typically roam in stable, social groups over large grazing territories, spending 16-20 hr per day foraging on mid- to poor-quality roughage. In contrast, today's elite show horses live in relatively small stalls, eat a limited-but rich-diet at specific feedings, and typically live in social isolation. Although the horse has been domesticated for more than 6000 years, there has been no selection for an equid who no longer requires an outlet for these natural behaviors. Using equine stereotypies as a welfare indicator, this researcher proposes that the psychological well being of today's performance horse is compromised. Furthermore, the article illustrates how minimal management changes can enhance horses' well being while still remaining compatible with the requirements of the sport-horse industry. The article discusses conclusions in terms of Fraser, Weary, Pajor, and Milligan's "integrative welfare model" (1997).

    2013-03-01

    Nominated as an outstanding contribution by Simon Fraser University. Demonstrates the power of isotopic enrichment for high-resolution spectroscopic characterization. Records properties of transition metal centers in silicon with unprecedented accuracy. A valuable step towards the realization of silicon-based lighting. The fundamental properties of deep luminescence centres in Si associated with transition metals such as Cu, Ag, Au, and Pt have been a focus of interest for decades, both as markers for these deleterious contaminants, and also in the quest for efficient Si-based light emission. This dissertation presents the results of ultra-high resolution photoluminescence studies of these centres in specially prepared, highly enriched 28-Si samples. The greatly improved spectral resolution due to this enrichment led to the discovery of isotopic fingerprints. These fingerprints have revealed that the detailed constituents of all of the centres previously studied had been identified incorrectly. They also revealed the existence of several different families of impurity complexes containing either four or five atoms chosen from Li, Cu, Ag, Au, and Pt. These centres' constituents have been determined, together with no-phonon transition energies, no-phonon isotope shifts, local vibrational mode energies, and the isotope shifts of the local vibrational mode energies. The data presented here for these centres should prove useful for the currently sought theoretical explanations of their formation, stability, and properties.

  18. Effects of ultraviolet-B irradiation on seedling growth in the Pinaceae

    1988-01-01

    Ten conifer species were grown in an unshaded greenhouse at the University of Maryland under 3 levels of biologically effective ultraviolet-B radiation. Ultraviolet-B radiation was supplied by Westinghouse FS-40 sunlamps and effective daily doses were 0, 12.4, and 19.1 kJ m-2. During the irradiation period, seedling growth and the development of stress symptoms were monitored. After 22 weeks of irradiation, seedlings were harvested and morphological characteristics analyzed. Visual symptoms included needle discoloration and stunting in three of the ten species tested. Seedling height was significantly reduced by supplemental UV-B in Pinus contorta (lodgepole pine), Pinus resinosa (red pine), and Pinus taeda (loblolly pine). Biomass increased in Picea engelmannii (Engelmann spruce). Abies fraseri (Fraser fir), Pinus edulus (pinyon pine), and Pinus nigra (black pine) were unaffected by UV-B while biomass reductions exceeding 5% were observed in all other species tested. These deleterious effects occurred despite the presence of morphological characteristics which would tend to reduce UV-B effectiveness. Generally, the effects of supplemental UV-B dose were less for those species native to higher elevations, implying the presence of natural adaptations to UV-B

    We have compiled available records in the literature for medusozoan cnidarians and ctenophores of South America. New records of species are also included. Each entry (i.e., identified species or still as yet not determined species referred to as "sp." in the literature) includes a synonymy list for South America, taxonomical remarks, notes on habit, and information on geographical occurrence. We have listed 800 unique determined species, in 958 morphotype entries: 5 cubozoans, 905 hydrozoans, 25 scyphozoans, 3 staurozoans, and 20 ctenophores. Concerning nomenclatural and taxonomical decisions, two authors of this census (Miranda, T.P. & Marques, A.C.) propose Podocoryna quitus as a nomen novum for the junior homonym Hydractinia reticulata (Fraser, 1938a); Euphysa monotentaculata Zamponi, 1983b as a new junior synonym of Euphysa aurata Forbes, 1848; and Plumularia spiralis Milstein, 1976 as a new junior synonym of Plumularia setacea (Linnaeus, 1758). Finally, we also reassign Plumularia oligopyxis Kirchenpauer, 1876 as Kirchenpaueria oligopyxis (Kirchenpauer, 1876) and Sertularella margaritacea Allman, 1885 as Symplectoscyphus margaritaceus (Allman, 1885).

    This study examined pools and fluxes of biomass, carbon (C) and nitrogen (N) in the overstory and understory of a southern Appalachian red spruce and Fraser fir forest after adelgid-induced fir mortality and spruce windthrow. Standing biomass and fluxes of all growth forms from periodic stand inventories, vegetation surveys, and allometric equations were estimated. Plant- and tissue-specific C and N concentrations were used to calculate total C and N pools and fluxes. Results of the study showed that total aboveground biomass re-attained values observed before the disturbances. Overstory biomass production and N uptake exceeded values observed in earlier reports. The woody overstory accounted for 3 per cent of all aboveground biomass as well as 10 per cent of annual productivity, and 19 per cent of total N uptake. It was concluded that the N-rich understory vegetation plays a significant role in N cycling, and contributed to overall productivity of the system. Further research is needed to examine the relationships between the over- and understories in order to investigate future changes in nutrient cycling. 60 refs., 2 tabs., 4 figs.

  1. Application of an entropy-based Bayesian optimization technique to the redesign of an existing monitoring network for single air pollutants.

    2009-06-01

    We apply the entropy-based Bayesian optimizing approach of Le and Zidek to the spatial redesign of the extensive air pollution monitoring network operated by Metro Vancouver, in the Lower Fraser Valley, British Columbia. This method is chosen because of its statistical sophistication, relative to other possible approaches, and because of the very rich, two-decade long data record available from this network. The redesign analysis is applied to ozone, carbon monoxide and PM(2.5) pollutants. The analysis provides guidance with regard to stations monitoring the three pollutants. For both ozone and PM(2.5), the analysis indicates a need for more stations in the eastern part of the monitoring domain. A parallel analysis indicates that stations may be removed from the more central parts of the domain. An analysis of the carbon monoxide network produces results that are not nearly as clearly defined as those for the other two pollutants, presumably because carbon monoxide is a primary pollutant with many locally important sources. The work demonstrates the great utility of the analysis technique, and also provides statistically defensible guidance on the spatial redesign of this important monitoring network.

  2. Mass balance and sliding velocity of the Puget lobe of the cordilleran ice sheet during the last glaciation

    Booth, D.B.

    1986-01-01

    An estimate of the sliding velocity and basal meltwater discharge of the Puget lobe of the Cordilleran ice sheet can be calculated from its reconstructed extent, altitude, and mass balance. Lobe dimensions and surface altitudes are inferred from ice limits and flow-direction indicators. Net annual mass balance and total ablation are calculated from relations empirically derived from modern maritime glaciers. An equilibrium-line altitude between 1200 and 1250 m is calculated for the maximum glacial advance (ca. 15,000 yr B.P.) during the Vashon Stade of the Fraser Glaciation. This estimate is in accord with geologic data and is insensitive to plausible variability in the parameters used in the reconstruction. Resultant sliding velocities are as much as 650 m/a at the equilibrium line, decreasing both up- and downglacier. Such velocities for an ice sheet of this size are consistent with nonsurging behavior. Average meltwater discharge increases monotonically downglacier to 3000 m3/sec at the terminus and is of a comparable magnitude to ice discharge over much of the glacier's ablation area. Palcoclimatic inferences derived from this reconstruction are consistent with previous, independently derived studies of late Pleistocene temperature and precipitation in the Pacific Northwest. ?? 1986.

    Full Text Available A growing number of funding agencies and international scholarly organizations are requesting that research data be made more openly available to help validate and advance scientific research. Thus, this is an opportune moment for research data repositories to partner with journal editors and publishers in order to simplify and improve data curation and publishing practices. One practical example of this type of cooperation is currently being facilitated by a two year (2012-2014 one million dollar Sloan Foundation grant, integrating two well-established open source systems: the Public Knowledge Project’s (PKP Open Journal Systems (OJS, developed by Stanford University and Simon Fraser University; and Harvard University’s Dataverse Network web application, developed by the Institute for Quantitative Social Science (IQSS. To help make this interoperability possible, an OJS Dataverse plugin and Data Deposit API are being developed, which together will allow authors to submit their articles and datasets through an existing journal management interface, while the underlying data are seamlessly deposited into a research data repository, such as the Harvard Dataverse. This practice paper will provide an overview of the project, and a brief exploration of some of the specific challenges to and advantages of this integration.

    This study compared the automated BAX PCR with the standard culture method (SCM) to detect Listeria monocytogenes in blue crab processing plants. Raw crabs, crabmeat, and environmental sponge samples were collected monthly from seven processing plants during the plant operating season, May through November 2006. For detection of L. monocytogenes in raw crabs and crabmeat, enrichment was performed in Listeria enrichment broth, whereas for environmental samples, demi-Fraser broth was used, and then plating on both Oxford agar and L. monocytogenes plating medium was done. Enriched samples were also analyzed by BAX PCR. A total of 960 samples were examined; 59 were positive by BAX PCR and 43 by SCM. Overall, there was no significant difference (P ≤ 0.05) between the methods for detecting the presence of L. monocytogenes in samples collected from crab processing plants. Twenty-two and 18 raw crab samples were positive for L. monocytogenes by SCM and BAX PCR, respectively. Twenty and 32 environmental samples were positive for L. monocytogenes by SCM and BAX PCR, respectively, whereas only one and nine finished products were positive. The sensitivities of BAX PCR for detecting L. monocytogenes in raw crabs, crabmeat, and environmental samples were 59.1, 100, and 60%, respectively. The results of this study indicate that BAX PCR is as sensitive as SCM for detecting L. monocytogenes in crabmeat, but more sensitive than SCM for detecting this bacterium in raw crabs and environmental samples.

    Full Text Available Aims: The aim of present study was determination of occurrence of Listeria Listeria spp. in various point of a municipal wastewater treatment plant. Materials and Methods: The samples were collected of influent, effluent, raw sludge, stabilized sludge and dried sludge from north wastewater treatment plant Isfahan, Iran. The presence of Listeria spp. was determined using USDA procedure and enumerated by a three-tube most probable number assay using Fraser enrichment broth. Then, biochemically identified Listeria monocytogenes was further confirmed by PCR amplification. Results: L. monocytogenes, L. innocua and L. seeligeri were isolated from 76.9%, 23.1% and 23.1% of influent, 38.5%, 46.2% and 7.7% of effluent, 84.6%, 69.2% and 46.2% of raw sludge, 69.2%, 76.9% and 0% of stabilized sludge and 46.2%, 7.7% and 0% of dried sludge samples, respectively. The efficiency of wastewater treatment processes, digester tank and drying bed in removal of L. monocytogenes were 69.6%, 64.7% and 73.4%, respectively. All phenotypically identified L. monocytogenes were further confirmed by PCR method. Conclusion: Application of sewage sludge in agricultural farms as fertilizer may result in bacteria spreading in agriculture fields and contaminated foods with plant origin. This may cause a risk of spreading disease to human and animals. Using parameters such as BOD 5 is not sufficient standard for the elimination of pathogenic microorganisms.

    Comments are offered on the 'First Report of the Ranger Uranium Environmental Inquiry' by a committee under the chairmanship of Mr. Justice Russell Fox, published by the Australian Government Publishing Service, October 1976, and the proposed parliamentary debate on same. The Fraser government, under protests by environmental movements, has announced a decision to allow mining to proceed on some U leases in order to fulfil existing export contracts with W. Germany, Japan, and the USA for a total of 10,700 tonnes of U oxide. The report is concerned with a proposal by the Ranger Uranium Mining Co. to recover 85,000 tonnes of U 3 0 8 from an area 200 km east of Darwin in Australia's remote Northern Territory. It appeared that there was no close concurrence between the views of the committee and the decisions of a government that is in favour of an expanding mining industry.

    2016-11-01

    Braconids are parasitoid insects which parasitize other insects by injecting their eggs into the larvae and eventually killing the hosts. Due to this character, braconids play an important role in stabilizing the natural and human-made environment. The objective of this study was to evaluate the diversity and distribution of braconids in two ecosystems. Nine Malaise traps were installed in each ecosystem for 30 days at five sampling sites, namely Bukit Rupa (BR), Bukit Fraser (BF), Ladang Zamrud (LZ), Felda Lui Muda (FLM) and Cherating (Ch). Samples were collected and kept in 75% alcohol for identification process. Two types of ecosystem were selected namely forest (secondary forest) and agricultural (oil palm plantation, star fruit orchard) ecosystems. A total of 1201 individuals were collected in 18 subfamilies and 137 morphospecies. From the results, BR showed the highest H', as it was a natural habitat for the braconids. FLM and LZ also showed high H' values, while Ch was the lowest. Based on the cluster analysis, the clade was divided into two groups; the oil palm plantation (LZ, FLM) and forest ecosystem (BF, BR). Ch was considered an outgroup because the braconid spesies found there were specific to Bactocera spp. Based on the rarefaction curve, LZ had the most stable curve compared to the others due to high sample size.

    A range of remote sensing tools can be used to document hazardous and sensitive environments. Presented at this time are the first results of an ongoing study of a rapidly eroding, steep sea cliff in Vancouver, British Columbia. The sea cliff is formed in a 70-m-thick sequence of outwash sands and silts (Quadra Sand) deposited during the early part of the last glaciation, known locally as the Fraser Glaciation. The sea cliff is unstable and retreating due to wave attack, groundwater seepage, and shallow-seated landslides. If no measures are taken to stem wave erosion, the sea cliff will likely retreat faster with rising seas over the remainder of this century. The beach below the cliff is a popular recreational location, thus a hard engineering solution to the erosion problem might be unacceptable to Vancouver residents. We have used conventional photogrammetry, structures from motion, thermal imaging, and terrestrial full waveform laser scanning to provide base-line spatial data for the most rapidly eroding section of the cliff. Here, we present some of our results and discuss the challenges that we faced in characterizing this large soil slope.

    Some outbreaks associated with contaminated duodenoscopes have been attributed to biofilm formation. The objective of this study was to determine whether bacteria within an organic matrix could survive if the elevator lever was improperly positioned in the automated endoscope reprocessor (AER) after 1 round of reprocessing. Duodenoscope lever cavities with an open or sealed elevator wire channel were inoculated with 6-7 Log 10 of both Escherichia coli and Enterococcus faecalis in ATS2015 (Healthmark Industries, Fraser, MI) and dried for 2 hours. The duodenoscopes with the lever in the horizontal position were processed through 2 makes of AERs. The cavity was sampled using a flush-brush-flush method to determine the quantity of surviving bacteria. E faecalis (range, 21-6 Log 10 CFU) and E coli (range, 0-3 Log 10 CFU) survived disinfection of sealed or unsealed elevator wire channel duodenoscopes in 2 different AERs with and without cleaning cycles. If bacteria in organic residue are under the improperly positioned lever, then just 1 round of use is sufficient for bacteria to survive both liquid chemical sterilization and liquid chemical HLD regardless of whether or not the AER had a cleaning cycle.

    In 1968, a child's cranium was recovered from the banks of a northern Canadian river and held in a trust until the "cold case" was reopened in 2005. The cranium underwent reanalysis at the Centre for Forensic Research, Simon Fraser University, using recently developed anthropological analysis, "bomb-pulse" radiocarbon analysis, and forensic DNA techniques. Craniometrics, skeletal ossification, and dental formation indicated an age-at-death of 4.4 ± 1 year. Radiocarbon analysis of enamel from two teeth indicated a year of birth between 1958 and 1962. Forensic DNA analysis indicated the child was a male, and the obtained mitochondrial profile matched a living maternal relative to the presumed missing child. These multidisciplinary analyses resulted in a legal identification 41 years after the discovery of the remains, highlighting the enormous potential of combining radiocarbon analysis with anthropological and mtDNA analyses in producing confident personal identifications for forensic cold cases dating to within the last 60 years. © 2012 American Academy of Forensic Sciences.

    An integrative taxonomic analysis based on the mitochondrial gene ND2 and its flanking tRNAs, morphology, and color pattern indicates that a newly discovered gecko described herein as Hemiphyllodactylus cicak sp. nov. from Penang Hill on the Island of Penang, Peninsular Malaysia is a member of the H. harterti group. Hemiphyllodactylus cicak sp. nov. is most closely related to the clade composed of the sister species H. harterti from Bukit Larut, Perak in the Bintang Mountain Range and H. bintik from Gunung Tebu, Terengganu from the Timur Mountain Range. These three allopatric species form a monophyletic group that extends approximately 270 km across three isolated mountain ranges in northern Peninsular Malaysia. The molecular analysis also indicates that H. titiwangsaensis from the Titiwangsa Mountain Range is composed of three genetically distinct allopatric populations. The southern two populations from Fraser's Hill and Genting Highlands, Pahang have an uncorrected pairwise sequence divergence of 3.5% whereas these two populations have 12.4 and 12.8 % sequence divergences, respectively, from the northern population at Cameron Highlands, Pahang. Although the high sequence divergence clearly distinguishes the southern two populations from the former as a different species, all three populations are morphologically indistinguishable, leading to the hypothesis of a true, cryptic speciation event.

  14. Urotensin II in cardiovascular regulation

    Full Text Available Fraser D RussellSchool of Health and Sport Sciences, Faculty of Science, Health and Education, University of the Sunshine Coast, Sippy Downs, Queensland, AustraliaAbstract: Cardiovascular function is modulated by neuronal transmitters, circulating hormones, and factors that are released locally from tissues. Urotensin II (UII is an 11 amino acid peptide that stimulates its’ obligatory G protein coupled urotensin II receptors (UT to modulate cardiovascular function in humans and in other animal species, and has been implicated in both vasculoprotective and vasculopathic effects. For example, tissue and circulating concentrations of UII have been reported to increase in some studies involving patients with atherosclerosis, heart failure, hypertension, preeclampsia, diabetes, renal disease and liver disease, raising the possibility that the UT receptor system is involved in the development and/or progression of these conditions. Consistent with this hypothesis, administration of UT receptor antagonists to animal models of cardiovascular disease have revealed improvements in cardiovascular remodelling and hemodynamics. However, recent studies have questioned this contributory role of UII in disease, and have instead postulated a protective effect on the cardiovascular system. For example, high concentrations of circulating UII correlated with improved clinical outcomes in patients with renal disease or myocardial infarction. The purpose of this review is to consider the regulation of the cardiovascular system by UII, giving consideration to methodologies for measurement of plasma concentrations, sites of synthesis and triggers for release.Keywords: urotensin II, cardiovascular disease, heart failure, hypertension

    Full Text Available O presente trabalho levanta a hipótese de que as ações de governo do PT estão inovando significativamente na necessária convergência (cf. Fraser, 1999; Honnetch, 2003 entre as tradicionais políticas de redistribuição sócio-econômica, e uma nova diretriz de reconhecimento das diferenças sócio-políticas e culturais. O argumento retoma a trajetória sindical do PT e os efeitos das políticas participativas, nas mudanças da cultura política em várias partes do país. Entre esses efeitos, o crescente apoio à democracia parece relacionar-se ao reconhecimento do direito à diferença e ao pluralismo - principalmente entre a juventude e naqueles locais onde o PT tem governado na última década

    BC Hydro commits $1.5 million annually to its Bridge Coastal Fish and Wildlife Restoration Program (BCRP) to support eligible fish and wildlife projects within the Bridge River/Coastal Generation Area which includes the Fraser Valley, Vancouver, Island, Coastal, Bridge River and Shuswap. This report was prepared for the Kwikwetlem Nation in reference to the Coquitlam/Buntzen Water Use Plan, the second of 32 proposed public reviews of hydroelectric complexes in British Columbia. The Coquitlam River flows through territory of the Kwikwetlem Nation who, historically, depended on sockeye salmon for their sustenance, trade, economy and culture. The BCRP is helping the Kwikwetlem to construct a salmon spawning channel in a former branch of the Coquitlam River near their reserves. This report compliments their project and is based on historic information on the disruption of former salmon migrations in the Coquitlam River system and the decision-making processes surrounding hydroelectric complex constructed by the Vancouver Power Company between 1903 and 1913. refs., figs

  17. Some Convex Functions Based Measures of Independence and Their Application to Strange Attractor Reconstruction

    Full Text Available The classical information-theoretic measures such as the entropy and the mutual information (MI are widely applicable to many areas in science and engineering. Csiszar generalized the entropy and the MI by using the convex functions. Recently, we proposed the grid occupancy (GO and the quasientropy (QE as measures of independence. The QE explicitly includes a convex function in its definition, while the expectation of GO is a subclass of QE. In this paper, we study the effect of different convex functions on GO, QE, and Csiszar’s generalized mutual information (GMI. A quality factor (QF is proposed to quantify the sharpness of their minima. Using the QF, it is shown that these measures can have sharper minima than the classical MI. Besides, a recursive algorithm for computing GMI, which is a generalization of Fraser and Swinney’s algorithm for computing MI, is proposed. Moreover, we apply GO, QE, and GMI to chaotic time series analysis. It is shown that these measures are good criteria for determining the optimum delay in strange attractor reconstruction.

    Horizontal directional drilling (HDD) is often used to install pipeline crossings beneath rivers, through mountains, or beneath urban infrastructure. HDD processes can often lead to the development of localized sinkholes and settlement above installed pipelines. This paper provided several examples of the unfavorable ground conditions and HDD installation procedures responsible for the development of sinkholes and settlement. Various mitigation measures designed to prevent both sinkhole and settlement from occurring after HDD installation were also presented. Case studies from 2 large HDD crossings were presented in order to illustrate the potential magnitude of post-HDD sinkholes and settlements at a crossing of the Fraser River located near Vancouver, British Columbia; and at major river crossing in north-central Argentina. Both case studies showed that large sinkholes formed behind HDD exit points, which resulted in property damage and eventually threatened the stability of neighbouring utilities. Triggering factors relating to unfavourable ground conditions included loose soils; compressible ground; fluctuating water tables; and high conductivity soils. Triggering factors relating to HDD installation methods included excessive annulus size; differences in entry/exit point elevation; excessive washing; and excessive circulating pressure. Several remediation options used in the case studies were also discussed, as well as site investigation and design techniques implemented to minimize the potential for sinkhole development. It was concluded that potential sinkhole and settlement triggering factors must be identified as early as possible during the construction and design phases of a project in order to allow for the implementation of mitigation measures. 6 refs., 8 figs.

  19. An Attempt to Assess the Quantitative Impact of Institutions on Economic Growth and Economic Development

    Full Text Available This study aims at assessing to what extent institutional environment is responsible for worldwide differences in economic growth and economic development. To answer this question, we use an innovative approach based on a new concept of the institutions-augmented Solow model which is then estimated empirically using regression equations. The analysis covers 180 countries during the 1993-2012 period. The empirical analysis confirms a large positive impact of the quality of institutional environment on the level of economic development. The positive link has been evidenced for all five institutional indicators: two indices of economic freedom (Heritage Foundation and Fraser Institute, the governance indicator (World Bank, the democracy index (Freedom House, and the EBRD transition indicator for post-socialist countries. Differences in physical capital, human capital, and institutional environment explain about 70-75% of the worldwide differences in economic development. The institutions-augmented Solow model, however, performs slightly poorer in explaining differences in the rates of economic growth: only one institutional variable (index of economic freedom has a statistically significant impact on economic growth. In terms of originality, this paper extends the theoretical analysis of the Solow model by including institutions, on the one hand, and shows a comprehensive empirical analysis of the impact of various institutional indicators on both the level of development and the pace of economic growth, on the other. The results bring important policy implications.

    Full text: Feather keratin is a highly conserved protein of 98 amino acids synthesized intracellularly in aves. In the cortex of the tail covert feathers of the peacock it forms a crystalline structure, held together by disulfide bonds between the nine cysteines of the molecule. Despite the biological importance of the molecule, its spatial structure has not yet been determined. Fraser and Parry proposed a crystallographic arrangement of beta-barrels and relegate the N-terminus and the C-terminus to an amorphous matrix, akin to the situation in silk. Therefore, in-situ tension and compression tests were made to investigate the changes in axial and lateral direction. Nanoscopically a pronounced structural asymmetry between tension and compression rules out a dihedral axis normal to the fibril direction, and indicates a strong clip-like polarization of the molecule. Based on these X-ray diffraction data from Pavo cristatus feathers, a model is presented for the axial and lateral arrangement of the molecule in feather keratin, which integrates biochemical structure and mechanical experiments.
