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.

Doubling sockeye salmon production in the Fraser River—Is this sustainable development?

Science.gov (United States)

Henderson, Michael A.; Healey, Michael C.

1993-11-01

We evaluate a proposal to double sockeye salmon production from the Fraser River and conclude that significant changes will be required to current management processes, particularly the way available catch is allocated, if the plan is to be consistent with five major principles embodied in the concept of sustainable development. Doubling sockeye salmon production will not, in itself, increase economic equity either regionally or globally. Developing nations may actually be hindered in their attempts to institute other, nonsalmon fisheries in the North Pacific Ocean as a result of the possible interception of salmon. Further, other users of the Fraser River basin will have to forgo opportunities so that salmon habitat can be conserved. If doubling sockeye salmon production is to meet the goal of doing more with less, it will be necessary to develop more efficient technologies to harvest the fish. If increasing salmon production is to reflect the integration of environmental and economic decision making at the highest level, then a serious attempt must be made to incorporate environmental assets into national economic accounting. Finally, to promote biodiversity and cultural self-sufficiency within the Fraser River basin, it will be important to safeguard the small, less-productive salmon stocks as well as the large ones and to allocate a substantial portion of the increased production to the Native Indian community.

A century of hydrological variability and trends in the Fraser River Basin

2012-01-01

This study examines the 1911–2010 variability and trends in annual streamflow at 139 sites across the Fraser River Basin (FRB) of British Columbia (BC), Canada. The Fraser River is the largest Canadian waterway flowing to the Pacific Ocean and is one of the world’s greatest salmon rivers. Our analyses reveal high runoff rates and low interannual variability in alpine and coastal rivers, and low runoff rates and high interannual variability in most streams in BC’s interior. The interannual variability in streamflow is also low in rivers such as the Adams, Chilko, Quesnel and Stuart where the principal salmon runs of the Fraser River occur. A trend analysis shows a spatially coherent signal with increasing interannual variability in streamflow across the FRB in recent decades, most notably in spring and summer. The upward trend in the coefficient of variation in annual runoff coincides with a period of near-normal annual runoff for the Fraser River at Hope. The interannual variability in streamflow is greater in regulated rather than natural systems; however, it is unclear whether it is predominantly flow regulation that leads to these observed differences. Environmental changes such as rising air temperatures, more frequent polarity changes in large-scale climate teleconnections such as El Niño-Southern Oscillation and Pacific Decadal Oscillation, and retreating glaciers may be contributing to the greater range in annual runoff fluctuations across the FRB. This has implications for ecological processes throughout the basin, for example affecting migrating and spawning salmon, a keystone species vital to First Nations communities as well as to commercial and recreational fisheries. To exemplify this linkage between variable flows and biological responses, the unusual FRB runoff anomalies observed in 2010 are discussed in the context of that year’s sockeye salmon run. As the climate continues to warm, greater variability in annual streamflow, and hence in

Full Text Available This paper compares of snowpack accumulation and ablation, evapotranspiration, and water outflow from clearcut and forested plots within a high elevation (2900 m mixed conifer forest at the Fraser Experimental Forest near Fraser, Colorado, USA. Also presented is a method for defining contributing area where outflow is measured from unbounded plots. Plots were monitored from 1980 to 1990 and again in 1993. The clearcut plot was harvested in late 1984. Evapotranspiration (ET of the forested plot at zero discharge (ETo was estimated at 426 mm while the ET was 500 mm at the mean precipitation of 596 mm. ET was dependent on precipitation with about 28% of precipitation input in excess of 426 mm contributing to increased ET, while the remainder contributed to increased outflow. During the six monitored post-harvest years, Peak Water Equivalent of the snowpack averaged 36% higher on the cut plot than on the control, and the mean discharge increased from 85 mm to 356 mm. Area estimates were obtained from the slopes of the regression of outflow on precipitation inputs. Hydrologic parameters corresponded closely to those previously determined at Fraser Experimental Forest using other methods, lending credence to the validity of the area estimates.

The book "Quantum Exodus" will be presented by the author Gordon Fraser on Thursday 14 June at 4 P.M. in the Library, Building 52-1-052.   "Quantum Exodus" by Gordon Fraser, Oxford University Press, 2012. Here's what the publisher says about the book: "It was no accident that the Holocaust and the Atomic Bomb happened at the same time. (...) Atomic science had attracted a lot of Jewish talent, and as Albert Einstein and other quantum exiles scattered, they realized that they held the key to a weapon of unimaginable power. Convinced that their gentile counterparts in Germany had come to the same conclusion, and having witnessed what the Nazis were prepared to do, the exiles were afraid. They had to get to the Atomic Bomb first. The Nazis meanwhile had acquired a more pressing objective: their persecution of the Jews had evolved into extermination. Two dreadfu...

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.

Supporting frail seniors through a family physician and Home Health integrated care model in Fraser Health

Directory of Open Access Journals (Sweden)

Grace Haeson Park

2014-03-01

Full Text Available Background: A major effort is underway to integrate primary and community care in Canada's western province of British Columbia and in Fraser Health, its largest health authority. Integrated care is a critical component of Fraser Health's planning, to meet the challenges of caring for a growing, elderly population that is presenting more complex and chronic medical conditions. Description of integrated practice: An integrated care model partners family physicians with community-based home health case managers to support frail elderly patients who live at home. It is resulting in faster response times to patient needs, more informed assessments of a patient's state of health and pro-active identification of emerging patient issues. Early results: The model is intended to improve the quality of patient care and maintain the patients’ health status, to help them live at home confidently and safely, as long as possible. Preliminary pilot data measuring changes in home care services is showing positive trends when it comes to extending the length of a person's survival/tenure in the community (living in their home vs. admitted to residential care or deceased. Conclusion: Fraser Health's case manager–general practitioner partnership model is showing promising results including higher quality, appropriate, coordinated and efficient care; improved patient, caregiver and physician interactions with the system; improved health and prevention of acute care visits by senior adult patients.

2011-05-09

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.

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

Crustal surface wave velocity structure of the east Albany-Fraser Orogen, Western Australia, from ambient noise recordings

Group and phase velocity maps in the period range 2-20 s for the Proterozoic east Albany-Fraser Orogen, Western Australia, are extracted from ambient seismic noise recorded with the 70-station ALFREX array. This 2 yr temporary installation provided detailed coverage across the orogen and the edge of the Neoarchean Yilgarn Craton, a region where no passive seismic studies of this scale have occurred to date. The surface wave velocities are rather high overall (>3 km s-1 nearly everywhere), as expected for exposed Proterozoic basement rocks. No clear signature of the transition between Yilgarn Craton and Albany-Fraser Orogen is observed, but several strong anomalies corresponding to more local geological features were obtained. A prominent, NE-elongated high-velocity anomaly in the northern part of the array is coincident with a Bouguer gravity high caused by the upper crustal metamorphic rocks of the Fraser Zone. This feature disappears towards longer periods, which hints at an exclusively upper crustal origin for this anomaly. Further east, the limestones of the Cenozoic Eucla Basin are clearly imaged as a pronounced low-velocity zone at short periods, but the prevalence of low velocities to periods of ≥5 s implies that the uppermost basement in this area is likewise slow. At longer periods, slightly above-average surface wave velocities are imaged below the Eucla Basin.

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

Science.gov (United States)

Llorente, Berta E; Larraburu, Ezequiel E

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.

Testing mitochondrial sequences and anonymous nuclear markers for phylogeny reconstruction in a rapidly radiating group: molecular systematics of the Delphininae (Cetacea: Odontoceti: Delphinidae

Directory of Open Access Journals (Sweden)

Kingston Sarah E

2009-10-01

Full Text Available Abstract Background Many molecular phylogenetic analyses rely on DNA sequence data obtained from single or multiple loci, particularly mitochondrial DNA loci. However, phylogenies for taxa that have undergone recent, rapid radiation events often remain unresolved. Alternative methodologies for discerning evolutionary relationships under these conditions are desirable. The dolphin subfamily Delphininae is a group that has likely resulted from a recent and rapid radiation. Despite several efforts, the evolutionary relationships among the species in the subfamily remain unclear. Results Here, we compare a phylogeny estimated using mitochondrial DNA (mtDNA control region sequences to a multi-locus phylogeny inferred from 418 polymorphic genomic markers obtained from amplified fragment length polymorphism (AFLP analysis. The two sets of phylogenies are largely incongruent, primarily because the mtDNA tree provides very poor resolving power; very few species' nodes in the tree are supported by bootstrap resampling. The AFLP phylogeny is considerably better resolved and more congruent with relationships inferred from morphological data. Both phylogenies support paraphyly for the genera Stenella and Tursiops. The AFLP data indicate a close relationship between the two spotted dolphin species and recent ancestry between Stenella clymene and S. longirostris. The placement of the Lagenodelphis hosei lineage is ambiguous: phenetic analysis of the AFLP data is consistent with morphological expectations but the phylogenetic analysis is not. Conclusion For closely related, recently diverged taxa, a multi-locus genome-wide survey is likely the most comprehensive approach currently available for phylogenetic inference.

Climate change and the Lower Fraser Valley. rev. ed.

International Nuclear Information System (INIS)

Taylor, E.; Langlois, D.

2000-01-01

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

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

Directory of Open Access Journals (Sweden)

Ivković Marjan

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“.

Effect of clear cutting on nutrient fluxes in a subalpine forest at Fraser, Colorado

Directory of Open Access Journals (Sweden)

J. O. Reuss

1997-01-01

Full Text Available Nutrient fluxes were investigated on a forested and a clearcut plot in a mixed conifer high elevation (2900 m forest at the Fraser Experimental Forest in Fraser, Colorado, USA. Plots were located on a coarse loamy mixed Dystric Cryochrept with relatively high base saturation (30-90% and underlain by an impermeable clay subsoil. Following harvest in late 1984, annual mean NO3 concentrations of 195 to 198 μmol l-1 were observed from 1988 through 1990 and concentrations were still above reference levels in 1993. Total nitrogen loss attributable to leaching following harvest was estimated at 48kg ha-1 over 8 years. Over this same period, atmospheric nitrogen inputs exceeded annual outflow of NH4 plus NO3 from the control plots by approximately 11 kg N ha-1. A slight enrichment Of SO4 and Cl was observed from the harvested plot in 1986 but concentrations later fell below control plot levels, apparently due to dilution by the increased discharge from the harvested plot which was three to four times that from the control plot. Elevated Ca, Mg, and Na concentrations followed a similar pattern to NO3 due to exchange reactions, while a depression in alkalinity of about one-third the amount of NO3 found was also observed. Enrichment of K occurred primarily in water collected at less than 1 m depth. Increases in base cation loss due to leaching after harvest were about twice the amount that can be accounted for by the increased flux of NO3, SO4, and Cl anions. The excess reflects the increased water flux and consequent leaching of base cations in association with HCO3 and organic anions.

Fraser Valley System Reinforcement Project: Environmental planning and assessment report

International Nuclear Information System (INIS)

1991-06-01

Transmission facilities in the south central Fraser Valley, British Columbia, need reinforcement in order to meet anticipated growth in power demand. This objective could be met by reinforcing substation facilities (adding 500-kV equipment and connection to transmission line 5L41) at the McLellan Substation in Surrey, at the Clayburn Substation in Matsqui, or at the Atchelitz Substation in Chilliwack. An assessment is provided of the environmental evaluation criteria applied to these potential sites for substation reinforcement and the rationale for selection of the Clayburn site as the environmentally most effective alternative. The Clayburn site is already cleared and managed for a 230-kV substation; environmental, land use, and socioeconomic impacts are considered manageable. The existing right-of-way for the 500-kV loop in to the substation can be utilized. In addition, the results of an environmental assessment and mitigation plan for the Clayburn substation reinforcement are described. The most significant factors that will require possible mitigative measures include fisheries, water quality, floodplain management, visual and recreational aspects, and heritage resources. 16 figs., 5 tabs

The impact of visual air quality on tourism revenues in Greater Vancouver and the Lower Fraser Valley

McNeill, R. [Environment Canada, Vancouver, BC (Canada); Roberge, A.

2000-07-01

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.

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

On the changing contribution of snow to the hydrology of the Fraser River Basin, Canada

Science.gov (United States)

Dery, S. J.; Kang, D.; Shi, X.; Gao, H.

2013-12-01

This talk will present an application of the Variable Infiltration Capacity (VIC) model to the Fraser River Basin (FRB) of British Columbia (BC), Canada over the latter half of the 20th century. The Fraser River is the longest waterway in BC and supports the world's most abundant Pacific Ocean salmon populations. Previous modeling and observational studies have demonstrated that the FRB is a snow-dominated system but with climate change it may evolve to a pluvial regime. Thus the goal of this study is to evaluate the changing contribution of snow to the hydrology of the watershed over the latter half of the 20th century. To this end, a 0.25° atmospheric forcing dataset is used to drive the VIC model from 1948 to 2006 at a daily time step over a domain covering the entire FRB. A model evaluation is first conducted over 11 major sub-watersheds of the FRB to quantitatively assess the spatial variations of snow water equivalent (SWE) and runoff. The ratio of the spatially averaged maximum SWE to runoff (RSR) is used to quantify the contribution of snow to the runoff in the 11 sub-watersheds of interest. From 1948 to 2006, RSR exhibits a significant decreasing trend in 9 of the 11 sub-watersheds (at a 0.05 of p-value according to the Mann-Kendall Test statistics). Changes in snow accumulation and melt lead to significant advances of the spring freshet throughout the basin. As the climate continues to warm, ecological processes and human usage of natural resources in the FRB may be substantially affected by its transition from a snow to a hybrid (nival/pluvial) and even a rain-dominated watershed.

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.

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)

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.

Dust records in the Pleistocene sediments of Fraser Island: palaeoclimatic reconstruction of wind erosion over the last 600 ka

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

Soil carbon is the carbon held within the soil, primarily in association with its organic content. The total soil organic carbon study was determined in a plot at Bukit Jeriau forest in Bukit Fraser, Pahang, Malaysia. The aim of this study is to determine the changing of soil organic carbon between wet season and dry season. Soil organic carbon was fined out using titrimetric determination. The soil organic carbon content in wet season is 223.24 t/ ha while dry season is 217.90 t/ ha. The soil pH range in wet season is between 4.32 to 4.45 and in dry season in 3.95 to 4.08 which is considered acidic. Correlation analysis showed that soil organic carbon value is influenced by pH value and climate. Correlation analysis between clay and soil organic carbon with depth showed positively significant differences and clay are very much influenced soil organic carbon content. Correlation analysis between electrical conductivity and soil organic carbon content showed negative significantly difference on wet season and positively significant different in dry season.

Examining controls on peak annual streamflow and floods in the Fraser River Basin of British Columbia

Science.gov (United States)

Curry, Charles L.; Zwiers, Francis W.

2018-04-01

The Fraser River Basin (FRB) of British Columbia is one of the largest and most important watersheds in western North America, and home to a rich diversity of biological species and economic assets that depend implicitly upon its extensive riverine habitats. The hydrology of the FRB is dominated by snow accumulation and melt processes, leading to a prominent annual peak streamflow invariably occurring in May-July. Nevertheless, while annual peak daily streamflow (APF) during the spring freshet in the FRB is historically well correlated with basin-averaged, 1 April snow water equivalent (SWE), there are numerous occurrences of anomalously large APF in below- or near-normal SWE years, some of which have resulted in damaging floods in the region. An imperfect understanding of which other climatic factors contribute to these anomalously large APFs hinders robust projections of their magnitude and frequency. We employ the Variable Infiltration Capacity (VIC) process-based hydrological model driven by gridded observations to investigate the key controlling factors of anomalous APF events in the FRB and four of its subbasins that contribute nearly 70 % of the annual flow at Fraser-Hope. The relative influence of a set of predictors characterizing the interannual variability of rainfall, snowfall, snowpack (characterized by the annual maximum value, SWEmax), soil moisture and temperature on simulated APF at Hope (the main outlet of the FRB) and at the subbasin outlets is examined within a regression framework. The influence of large-scale climate modes of variability (the Pacific Decadal Oscillation (PDO) and the El Niño-Southern Oscillation - ENSO) on APF magnitude is also assessed, and placed in context with these more localized controls. The results indicate that next to SWEmax (univariate Spearman correlation with APF of ρ ^ = 0.64; 0.70 (observations; VIC simulation)), the snowmelt rate (ρ ^ = 0.43 in VIC), the ENSO and PDO indices (ρ ^ = -0.40; -0.41) and (�

A homozygous missense variant in VWA2, encoding an interactor of the Fraser-complex, in a patient with vesicoureteral reflux.

Full Text Available 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.

Full Text Available In tropical areas especially during monsoon seasons intense precipitation is the main caused that trigger the natural shallow landslide phenomena. This phenomenon can be disastrous and widespread in occurrence even in undisturbed forested catchment. In this paper, an attempt has been made to evaluate the susceptibility of natural hill slopes to failure for a popular hill resort area, the Fraser Hill Catchment under different rainfall regimes and soil thickness. A Digital Elevation Model (DEM was prepared for the 8.2 km2 catchment. A GIS based deterministic model was then applied to predict the spatial landslide occurrence within catchment. Model input parameters include bulk density, friction angle, cohesion and hydraulic conductivity were gathered through in situ and lab analysis as well as from previous soil analysis records. Landslides locations were recorded using GPS as well as previous air photos and satellite imagery to establish landslide source areas inventory. The landslide susceptibility map was produced under different precipitation event’s simulation to see the effects of precipitation to stability of the hill slopes of the catchment. The results were categorized into naturally unstable (Defended, Upper Threshold, Lower Threshold, marginal instability (Quasi Stable and stable area (Moderately Stable and Stable. Results of the simulation indicated notable change in precipitation effect on Defended area is between 10mm to 40mm range in a single storm event. However, when storm event is exceeded 120mm, the result on Defended area produced by the model tends to be constant further on. For area categorized as naturally unstable (Factor of Safety, SF<1, with 110 mm of precipitation in a single storm event and soil depth at 2 meters and 4 meters could affect 69.51% and 69.88% respectively of the catchment area fall under that class.

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.

Reconstructing a sediment pulse: Modeling the effect of placer mining on Fraser River, Canada

Gold mining along 525 km of the Fraser River between 1858 and 1909 added an estimated 1.1 × 108 t of tailings, half gravel and the rest finer, to the river's natural sediment load. We simulate the response using a 1-D multigrain size morphodynamic model. Since premining conditions are unknown and modern data are insufficient for tuning the process representation, we devised a novel modeling strategy which may be useful in other data-poor applications. We start the model from a smoothed version of the modern longitudinal profile with bed grain size distributions optimized to match alternative assumptions about natural sediment supply and compare runs that include mining with control runs that can be used to quantify the effects of deficiencies in process representation and initialization. Simulations with an appropriate choice of natural supply rate closely match the best available test data, which consist of a detailed 1952-1999 gravel budget for the distal part of the model domain. The simulations suggest that the main response to mining was rapid bed fining, which allowed a major increase in bed load transport rate with only slight (~0.1 m) mean aggradation within the mining region and most of the excess sediment exported well beyond the mountain front within the mining period or soon afterward. We compare this pattern of response by a large, powerful river with previous case studies of river adjustment to sediment supply change.

Full Text Available O feminismo pós-estruturalista é a escolha teórica que, em grande parte, orienta aqui nossa perspectiva. Os debates em torno das noções de “direito”, “justiça” e “reconhecimento” ilustram essa discussão. Propomo-nos a fazer uma reflexão sociológica conceitual, de orientação feminista, de forma a constituir um suporte teórico para análises sobre políticas sociais, com o objetivo de investigar as condições de cidadania das mulheres pobres e apreender os determinantes de gênero presentes nos programas estatais. Ao tratar das categorias apontadas, adotamos o modelo proposto por Nancy Fraser, a qual combina a luta pela justiça redistributiva com a luta por justiça de reconhecimento.

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 Fraser River Basin (FRB) is the largest river draining to the Pacific Ocean in British Columbia (BC), Canada, and it provides the world's most abundant salmon populations. With recent climate change, the shifting hydrologic regime of the FRB is evaluated using hydrological modeling results over the period 1949 to 2006. To quantify the contribution of snowmelt to runoff generation, the ratio RSR, defined as the division of the sum of the snowmelt across the watershed by the integrated runoff over the water year, is employed. Modeled results for RSR at Hope, BC — the furthest downstream hydrometric station of the FRB — show a significant decrease (from 0.80 to 0.65) in the latter part of the 20th century. RSR is found to be mainly suppressed by a decrease of the snowmelt across the FRB with a decline with 107 mm by 26 % along the simulation period. There is also a prominent shift in the timing of streamflow, with the spring freshet at Hope, BC advancing 30 days followed by reduced summer flows for over two months. The timing of the peak spring freshet becomes even earlier when moving upstream of the FRB owing to short periods of time after melting from the snow source to the rivers.

Sedimentology of Fraser River delta peat deposits: a modern analogue for some deltaic coals

Energy Technology Data Exchange (ETDEWEB)

Styan, W B; Bustin, R M

1984-01-01

On the Recent lobe of the Fraser River delta, peat accumulation has actively occurred on the distal lower delta plain, the transition between upper and lower delta plains, and the alluvial plain. Distal lower delta plain peats developed from widespread salt and brackish marshes and were not influenced appreciably by fluvial activity. Lateral development of the marsh facies were controlled by compaction and eustatic sea-level rise. The resulting thin, discontinuous peat network contains numerous silty clay partings and high concentrations of sulphur. Freshwater marsh facies formed but were later in part eroded and altered by transgressing marine waters. Peats overlie a thin, fluvial, fining-upward sequence which in turn overlies a thick, coarsening-upward, prodelta-delta front succession. Lower- upper delta plain peats initially developed from interdistributary brackish marshes and were later fluvially influenced as the delta prograded. Thickest peats occur in areas where distributary channels were abandoned earliest. Sphagnum biofacies replace sedge-grass-dominated communities except along active channel margins, where the sedge-grass facies is intercalated with overbank and splay deposits. Peats are underlain by a relatively thin sequence of fluvial deposits which in turn is underlain by a major coarsening-upward delta front and pro-delta sequence. Alluvial plain peats accumulated in back swamp environments of the flood plain. Earliest sedge-clay and gyttja peats developed over thin fining-upward fluvial cycles or are interlaminated with fine-grained flood deposits. Thickest accumulations occur where peat fills small avulsed flood channels. Overlying sedge-grass and sphagnum biofacies are horizontally stratified and commonly have sharp boundaries with fine-grained flood sediments. At active channel margins, however, sedge-grass peats are intercalated with natural levee deposits consisting of silty clay.

Hydrological variability in the Fraser River Basin during the 20th century: A sensitivity study with the VIC model

Kang, D.; Gao, H.; Dery, S. J.

2012-12-01

The Variable Infiltration Capacity (VIC) model, a macroscale surface hydrology model, was applied to the Fraser River Basin (FRB) of British Columbia, Canada. Previous modeling studies have demonstrated that the FRB is a snow-dominated system but with climate change may evolve to a pluvial regime. The ultimate goal of this model application is to evaluate the changing contribution of snowmelt to streamflow in the FRB both spatially and temporally. To this end, the National Centers for Environmental Prediction (NCEP) reanalysis data combined with meteorological observations over 1953 to 2006 are used to drive the model at a resolution of 0.25°. Model simulations are first validated with daily discharge observations from the Water Survey of Canada (WSC). In addition, the snow water equivalent (SWE) results from VIC are compared with snow pillow observations from the B.C. Ministry of Environment. Then peak SWE values simulated each winter are compared with the annual runoff data to quantify the changing contribution of snowmelt to the hydrology of the FRB. With perturbed model forcings such as precipitation and air temperature, how streamflow and surface energy-mass balance are changed is evaluated. Finally, interactions between the land surface and ambient atmosphere are evaluated by analyzing VIC results such as evaporation, soil moisture, snowmelt and sensible-latent heat flux with corresponding meteorological forcings, i.e. precipitation and air temperature.

Assessing the full costs of water, liquid waste, energy and solid waste infrastructure in the Fraser Valley Regional District (FVRD)

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. The software can be viewed by contacting the Sheltair Group Resource Consultants Inc. in Vancouver

Effect of subalpine canopy removal on snowpack, soil solution, and nutrient export, Fraser Experimental Forest, CO

Research on the effects of vegetation manipulation on snowpack, soil water, and streamwater chemistry and flux has been underway at the Fraser Experimental Forest (FEF), CO, since 1982. Greater than 95% of FEF snowmelt passes through watersheds as subsurface flow where soil processes significantly alter meltwater chemistry. To better understand the mechanisms accounting for annual variation in watershed streamwater ion concentration and flux with snowmelt, we studied subsurface water flow, its ion concentration, and flux in conterminous forested and clear cut plots. Repetitive patterns in subsurface flow and chemistry were apparent. Control plot subsurface flow chemistry had the highest ion concentrations in late winter and fall. When shallow subsurface flow occurred, its Ca2+, SO42-, and HCO3- concentrations were lower and K+ higher than deep flow. The percentage of Ca2+, NO3-, SO42-, and HCO3- flux in shallow depths was less and K+ slightly greater than the percentage of total flow. Canopy removal increased precipitation reaching the forest floor by about 40%, increased peak snowpack water equivalent (SWE) > 35%, increased the average snowpack Ca2+, NO3-, and NH4+ content, reduced the snowpack K+ content, and increased the runoff four-fold. Clear cutting doubled the percentage of subsurface flow at shallow depths, and increased K+ concentration in shallow subsurface flow and NO3- concentrations in both shallow and deep flow. The percentage change in total Ca2+, SO42-, and HCO3- flux in shallow depths was less than the change in water flux, while that of K+ and NO3- flux was greater. Relative to the control, in the clear cut the percentage of total Ca2+ flux at shallow depths increased from 5 to 12%, SO42- 5.4 to 12%, HCO3- from 5.6 to 8.7%, K+ from 6 to 35%, and NO3- from 2.7 to 17%. The increases in Ca2+ and SO42- flux were proportional to the increase in water flux, the flux of HCO3- increased proportionally less than water flux, and NO3- and K+ were

Potential Effects of Dams on Migratory Fish in the Mekong River: Lessons from Salmon in the Fraser and Columbia Rivers

Ferguson, John W.; Healey, Michael; Dugan, Patrick; Barlow, Chris

2011-01-01

We compared the effects of water resource development on migratory fish in two North American rivers using a descriptive approach based on four high-level indicators: (1) trends in abundance of Pacific salmon, (2) reliance on artificial production to maintain fisheries, (3) proportion of adult salmon that are wild- versus hatchery-origin, and (4) number of salmon populations needing federal protection to avoid extinction. The two rivers had similar biological and physical features but radically different levels of water resource development: the Fraser River has few dams and all are located in tributaries, whereas the Columbia River has more than 130 large mainstem and tributary dams. Not surprisingly, we found substantial effects of development on salmon in the Columbia River. We related the results to potential effects on migratory fish in the Mekong River where nearly 200 mainstem and tributary dams are installed, under construction, or planned and could have profound effects on its 135 migratory fish species. Impacts will vary with dam location due to differential fish production within the basin, with overall effects likely being greatest from 11 proposed mainstem dams. Minimizing impacts will require decades to design specialized fish passage facilities, dam operations, and artificial production, and is complicated by the Mekong's high diversity and productivity. Prompt action is needed by governments and fisheries managers to plan Mekong water resource development wisely to prevent impacts to the world's most productive inland fisheries, and food security and employment opportunities for millions of people in the region.

This study provided estimates the health benefits and costs associated with specified changes in ambient air concentrations of particulate matter (PM) and ozone in the Lower Fraser Valley (LFV). Estimates were developed on a regional level. The study focused on PM and ozone, as current air quality monitoring data and scientific findings have indicated that these are the air contaminants of greatest concern in the region. Known air quality health outcome relationships were applied in a spreadsheet model to predict changes in health outcomes associated with 6 ambient air quality scenarios for 3 sub-regions within the LFV airshed. Concentration response functions based on epidemiological studies were used to estimate the number of health events associated with changes in air quality. For each scenario, the model calculated the expected number of the following health outcomes: mortality; chronic bronchitis; respiratory hospital admissions; cardiac hospital admissions; emergency room visits; child acute bronchitis; restricted activity days; asthma symptom days; minor restricted activity days and acute respiratory symptom days. The model also produced the dollar value of the health outcomes. A dollar metric was used so that the health outcomes could be aggregated and compared with other air quality management actions such the costs of improving ambient air quality. Results indicated that improving ambient air quality in the LFV will produce valued and socially desirable benefits, including reduced mortality and morbidity. The measures contemplated by decision-makers to maintain and improve air quality in the LFV will trigger benefits that are likely to be significant. 101 refs., 7 tabs., 7 figs.

Short episodic high temperature events can be lethal for migrating adult Pacific salmon (Oncorhynchus spp.). We downscaled temperatures for the Fraser River, British Columbia to evaluate the impact of climate warming on the frequency of exceeding thermal thresholds associated with salmon migratory success. Alarmingly, a modest 1.0 C increase in average summer water temperature over 100 years (1981-2000 to 2081-2100) tripled the number of days per year exceeding critical salmonid thermal thresholds (i.e. 19.0 C). Refined thresholds for two populations (Gates Creek and Weaver Creek) of sockeye salmon (Oncorhynchus nerka) were defined using physiological constraint models based on aerobic scope. While extreme temperatures leading to complete aerobic collapse remained unlikely under our warming scenario, both populations were increasingly forced to migrate upriver at reduced levels of aerobic performance (e.g. in 80% of future simulations, => 90% of salmon encountered temperatures exceeding population specific thermal optima for maximum aerobic scope; T(sub opt)) = 16.3 C for Gates Creek and T(sub sopt)=14.5 C for Weaver Creek). Assuming recent changes to river entry timing persist, we also predicted dramatic increases in the probability of freshwater mortality for Weaver Creek salmon due to reductions in aerobic, and general physiological, performance (e.g. in 42% of future simulations =>50% of Weaver Creek fish exceeded temperature thresholds associated with 0 - 60% of maximum aerobic scope). Potential for adaptation via directional selection on run-timing was more evident for the Weaver Creek population. Early entry Weaver Creek fish experienced 25% (range: 15 - 31%) more suboptimal temperatures than late entrants, compared with an 8% difference (range: 0 - 17%) between early and late Gates Creek fish. Our results emphasize the need to consider daily temperature variability in association with population-specific differences in behaviour and physiological

The nocturnal nitrogen oxides, which include the nitrate radical (NO3), dinitrogen pentoxide (N2O5), and its uptake product on chloride containing aerosol, nitryl chloride (ClNO2), can have profound impacts on the lifetime of NOx ( = NO + NO2), radical budgets, and next-day photochemical ozone (O3) production, yet their abundances and chemistry are only sparsely constrained by ambient air measurements. Here, we present a measurement data set collected at a routine monitoring site near the Abbotsford International Airport (YXX) located approximately 30 km from the Pacific Ocean in the Lower Fraser Valley (LFV) on the west coast of British Columbia. Measurements were made from 20 July to 4 August 2012 and included mixing ratios of ClNO2, N2O5, NO, NO2, total odd nitrogen (NOy), O3, photolysis frequencies, and size distribution and composition of non-refractory submicron aerosol (PM1). At night, O3 was rapidly and often completely removed by dry deposition and by titration with NO of anthropogenic origin and unsaturated biogenic hydrocarbons in a shallow nocturnal inversion surface layer. The low nocturnal O3 mixing ratios and presence of strong chemical sinks for NO3 limited the extent of nocturnal nitrogen oxide chemistry at ground level. Consequently, mixing ratios of N2O5 and ClNO2 were low ( formation of ClNO2 in the nocturnal residual layer aloft than at the surface and the breakup of the nocturnal boundary layer structure in the morning. When quantifiable, production of ClNO2 from N2O5 was efficient and likely occurred predominantly on unquantified supermicron-sized or refractory sea-salt-derived aerosol. After sunrise, production of Cl radicals from photolysis of ClNO2 was negligible compared to production of OH from the reaction of O(1D) + H2O except for a short period after sunrise.

A stochastic model describing the growth of Listeria monocytogenes during enrichment in half Fraser was developed for the purpose of estimating the effects of modifications to the first enrichment step of the EN ISO 11290-1 detection method. Information pertaining to the variability of growth rates, physiological state of the cell, and the behavior of individual cells contaminating the food were obtained from previously published studies. We used this model to investigate the impact of pooling enrichment broths (wet pooling) on the performance of the standard method. For validation of the model, the numbers of L. monocytogenes occurring in 88 naturally contaminated foods following pre-enrichment were compared to model-simulated microbial counts. The model was then used to perform simulations representative of the natural contamination observed for smoked salmon in the European baseline survey of 2010-2011. The model-estimated L. monocytogenes levels following individual enrichment or following the pooling of five broths where only one would be contaminated were compared. The model indicated a 10% loss of method sensitivity resulting from wet pooling. The model also predicted a 5% decrease in the sensitivity of the method when the duration of the enrichment was reduced from 24 to 22 h. Copyright © 2016 Elsevier Ltd. All rights reserved.

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 modeling 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 hr 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 more than twofold, it had skill in forecasting the relative species contribution to visibility impairment, including ammonium sulfate 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 postprocessed air quality forecasts without additional statistical modeling, 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.

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.

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.

Successful research collaboration exists between the University of the Fraser Valley (UFV), a primarily undergraduate-serving university located on the Fraser River in British Columbia, and the World Rivers Observatory that is coordinated through the Woods Hole Oceanographic Institution (WHOI) and the Woods Hole Research Center (WHRC). The World Rivers Observatory coordinates time-series sampling of 15 large rivers, with particular focus on the large Arctic rivers, the Ganges-Brahmaputra, Congo, Fraser, Yangtze (Changjiang), Amazon, and Mackenzie River systems. The success of this international observatory critically depends on the participation of local collaborators, such as UFV, that are necessary in order to collect temporally resolved data from these rivers. Several faculty members and undergraduate students from the Biology and Geography Departments of UFV received on-site training from the lead-PIs of the Global Rivers Observatory. To share information and ensure good quality control of sampling methods, WHOI and WHRC hosted two international workshops at Woods Hole for collaborators. For the past four years, faculty and students from UFV have been collecting a variety of bi-monthly water samples from the Fraser River for the World Rivers Observatory. UFV undergraduate students who become involved learn proper sampling techniques and are given the opportunity to design and conduct their own research. Students have collected, analyzed and presented data from this project at regional, national, and international scientific meetings. UFV undergraduate students have also been hosted by WHOI and WHRC as guest students to work on independent research projects. While at WHOI and WHRC, students are able to conduct research using state-of-the-art specialized research facilities not available at UFV.

During the past six years, new species of the genus Listeria have been isolated from foods and other environmental niches worldwide. The Standard method EN ISO 11290-1 that is currently under revision will include in its scope all Listeria species in addition to L. monocytogenes. The objective of this project was to evaluate the ability of the Standard EN ISO 11290-1 method to detect and identify the newly discovered Listeria spp., and to assess potential over-growth effects of the new species in mixed cultures with L. monocytogenes during each step of the enrichment process. This objective was addressed by the generation of necessary data on the behavior of the new species during the pre-enrichment and the enrichment steps of the reference method as well as data on their phenotypic characteristics on rich and selective media used for isolation and identification. Most of the new Listeria species developed well on selective agar media for Listeria, however the recovery of some species was difficult due to poor growth in Half Fraser and Fraser broth. Good results (consistently positive) were obtained for confirmation at the genus level via the catalase test, the Gram test and the blueish appearance test on non-selective medium, but not with the VP test, as most of the new species yielded a negative result. In the light of results obtained in co-culture experiments and inhibition tests, and considering the growth rates in Half Fraser and Fraser broths, the new species do not seem to interfere with the detection of L. monocytogenes.

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.

Full fuel cycle emissions reductions through the replacement of ICEVs with BEVs

International Nuclear Information System (INIS)

Lewison, T.

2001-01-01

The objective of the project was to calculate the changes in Greenhouse Gas emissions, non-GHG emissions and total energy consumption for the Lower Fraser Valley (LFV) for the year 2005 which would result based on the substitution of 'fleet average' gasoline internal combustion engine vehicles with comparably sized battery electric vehicles. Various electricity generating scenarios are analyzed which are representative of Canada's diverse electricity generation mix between provinces. While the analysis is based on vehicle population and emission inventory data for the Lower Fraser Valley, the vehicle data can easily be considered to be generic in nature and can be directly applied to most regional and Provincial scenarios across Canada, with virtually no degradation of the resultant accuracy. This document is intended to serve as a project summary document, rather than a detailed technical paper, and for this reason describes only key input parameters as well as key findings. (author)

Akya, A; Najafi, A; Moradi, J; Mohebi, Z; Adabagher, S

2013-05-01

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.

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

Science.gov (United States)

Ydenberg, Ronald C; Dekker, Dick; Kaiser, Gary; Shepherd, Philippa C F; Ogden, Lesley Evans; Rickards, Karen; Lank, David B

2010-01-21

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.

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

Full Text Available Abstract Background 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.

Survival of migrating salmon smolts in large rivers with and without dams.

Directory of Open Access Journals (Sweden)

David W Welch

2008-10-01

Full Text Available The mortality of salmon smolts during their migration out of freshwater and into the ocean has been difficult to measure. In the Columbia River, which has an extensive network of hydroelectric dams, the decline in abundance of adult salmon returning from the ocean since the late 1970s has been ascribed in large measure to the presence of the dams, although the completion of the hydropower system occurred at the same time as large-scale shifts in ocean climate, as measured by climate indices such as the Pacific Decadal Oscillation. We measured the survival of salmon smolts during their migration to sea using elements of the large-scale acoustic telemetry system, the Pacific Ocean Shelf Tracking (POST array. Survival measurements using acoustic tags were comparable to those obtained independently using the Passive Integrated Transponder (PIT tag system, which is operational at Columbia and Snake River dams. Because the technology underlying the POST array works in both freshwater and the ocean, it is therefore possible to extend the measurement of survival to large rivers lacking dams, such as the Fraser, and to also extend the measurement of survival to the lower Columbia River and estuary, where there are no dams. Of particular note, survival during the downstream migration of at least some endangered Columbia and Snake River Chinook and steelhead stocks appears to be as high or higher than that of the same species migrating out of the Fraser River in Canada, which lacks dams. Equally surprising, smolt survival during migration through the hydrosystem, when scaled by either the time or distance migrated, is higher than in the lower Columbia River and estuary where dams are absent. Our results raise important questions regarding the factors that are preventing the recovery of salmon stocks in the Columbia and the future health of stocks in the Fraser River.

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.

Snowmobile impacts on snowpack physical and mechanical properties

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.

Difficulties in conducting a randomized controlled trial of health service interventions in intellectual disability: implications for evidence-based practice.

Science.gov (United States)

Oliver, P C; Piachaud, J; Done, J; Regan, A; Cooray, S; Tyrer, P

2002-05-01

In an era of evidence-based medicine, practice is constantly monitored for quality in accordance with the needs of clinical governance (Oyebode et al. 1999). This is likely to lead to a dramatic change in the treatment of those with intellectual disability (ID), in which evidence for effective intervention is limited for much that happens in ordinary practice. As Fraser (2000, p. 10) has commented, the word that best explains "the transformation of learning disability practice in the past 30 years is 'enlightenment'." This is not enough to satisfy the demands of evidence, and Fraser exhorted us to embrace more research-based practice in a subject that has previously escaped randomized controlled trials (RCTs) of treatment because of ethical concerns over capacity and consent, which constitute a denial of opportunity which "is now at last regarded as disenfranchising". The present paper describes the difficulties encountered in setting up a RCT of a common intervention, i.e. assertive community treatment, and concludes that a fundamental change in attitudes to health service research in ID is needed if proper evaluation is to prosper.

The paper summarized the R and D of sewing assembly technology which is an element technology of an automatic sewing system by the Automatic Sewing System Technology Research Association. This technology is divided into three: (1) sewing pretreatment technology; (2) high functional sewing technology; (3) sub-element technology of high functional press technology. In (1), the process adaptability of bonding technology was evaluated to study the shape retention effect and processability. A bonding method was developed in which the thermal cross-linking silan denaturated polyamide adhesive PA-115 and the foaming agent are combinedly used. A study for improvement was conducted of a prototype using drum type photoconductor. A thread type adhesive supply unit for sewing substitution was developed. The high frequency inductive heating adhesive was evaluated. In (2), problems were bettered on the conventional system of 3D sewing technology. Improvement/design were made of the looper thread automatic supply type sewing mechanism of super stitching unit. The multi-functional sewing system is very practical. In (3), the following were conducted: study for improvement of flexible dummy, turntable unit loaded with two dummies, study for size reduction of sleeve frame driving unit and shape setting, study for setting of press conditions, and operational evaluation.

This paper describes the sewing and assembling technology, extracted from the achievement report for fiscal 1986 on developing an automatic sewing system. The sewing pretreatment technology has made it possible to express performance requirement of inner lining compounded cloths in numerals objectively to some extent. Discussions are being given in different ways on inner lining substituting technologies to improve elasticity and volume feeling in cloths. The high-frequency induction heating system has made it possible to attain bond compounded cloths of high quality. The three-dimensional sewing technology has improved largely the positioning and supporting performances of the automatic sleeve fitting system. A prospect was achieved in the cloth movement amount detecting technology for automatic cloth feed control. A cylindrical form sewing system, which has realized cloth tension control, made a study focussed on the object processes possible in the future. The automatic looper thread feeding type sewing mechanism using the super sewing technology had each function increased in stability, but improvement in maintainability is important when the mechanism is mounded in a sewing machine. The high-function press processing technology will continue its progress into fiscal 1987 by utilizing the achievements made to date, such as utilization of flexible dummies, establishment of pressing conditions, and prototype of a three-dimensional pressing device.

White Sturgeon, Acipenser transmontanus (WS), are distributed throughout three major river basins on the West Coast of North America: the Sacramento-San Joaquin, Columbia, and Fraser River drainages. Considered the largest North American freshwater fish, some WS use estuarine habitat and make limited marine movements between river basins. Some populations are listed by the United States or Canada as threatened or endangered (upper Columbia River above Grand Coulee Dam; Kootenai River; lower, middle and, upper Fraser River and Nechako River), while others do not warrant federal listing at this time (Sacramento-San Joaquin Rivers; Columbia River below Grand Coulee Dam; Snake River). Threats that impact WS throughout the species’ range include fishing effects and habitat alteration and degradation. Several populations suffer from recruitment limitations or collapse due to high early life mortality associated with these threats. Efforts to preserve WS populations include annual monitoring, harvest restrictions, habitat restoration, and conservation aquaculture. This paper provides a review of current knowledge on WS life history, ecology, physiology, behavior, and genetics and presents the status of WS in each drainage. Ongoing management and conservation efforts and additional research needs are identified to address present and future risks to the species.

Conversion of paper sludge to ethanol, II: process design and economic analysis.

Fan, Zhiliang; Lynd, Lee R

2007-01-01

Process design and economics are considered for conversion of paper sludge to ethanol. A particular site, a bleached kraft mill operated in Gorham, NH by Fraser Papers (15 tons dry sludge processed per day), is considered. In addition, profitability is examined for a larger plant (50 dry tons per day) and sensitivity analysis is carried out with respect to capacity, tipping fee, and ethanol price. Conversion based on simultaneous saccharification and fermentation with intermittent feeding is examined, with ethanol recovery provided by distillation and molecular sieve adsorption. It was found that the Fraser plant achieves positive cash flow with or without xylose conversion and mineral recovery. Sensitivity analysis indicates economics are very sensitive to ethanol selling price and scale; significant but less sensitive to the tipping fee, and rather insensitive to the prices of cellulase and power. Internal rates of return exceeding 15% are projected for larger plants at most combinations of scale, tipping fee, and ethanol price. Our analysis lends support to the proposition that paper sludge is a leading point-of-entry and proving ground for emergent industrial processes featuring enzymatic hydrolysis of cellulosic biomass.

Regulation of PDGFC signalling and extracellular matrix composition by FREM1 in mice

Directory of Open Access Journals (Sweden)

Fenny Wiradjaja

2013-11-01

Fras1-related extracellular matrix protein 1 (FREM1 is required for epidermal adhesion during embryogenesis, and mice lacking the gene develop fetal skin blisters and a range of other developmental defects. Mutations in members of the FRAS/FREM gene family cause diseases of the Fraser syndrome spectrum. Embryonic epidermal blistering is also observed in mice lacking PdgfC and its receptor, PDGFRα. In this article, we show that FREM1 binds to PDGFC and that this interaction regulates signalling downstream of PDGFRα. Fibroblasts from Frem1-mutant mice respond to PDGFC stimulation, but with a shorter duration and amplitude than do wild-type cells. Significantly, PDGFC-stimulated expression of the metalloproteinase inhibitor Timp1 is reduced in cells with Frem1 mutations, leading to reduced basement membrane collagen I deposition. These results show that the physical interaction of FREM1 with PDGFC can regulate remodelling of the extracellular matrix downstream of PDGFRα. We propose that loss of FREM1 function promotes epidermal blistering in Fraser syndrome as a consequence of reduced PDGFC activity, in addition to its stabilising role in the basement membrane.

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.

This paper describes the sewing preparation and processing technology from the achievement report for fiscal 1986 on developing an automatic sewing system. For the cloth property evaluation technology, such devices were used to measure different kinds of cloths and evaluate cloth properties related to sewing performance, as the KES testing machine, the measuring device for composite transformation, large transformation and bending, and composite surface properties, the cloth air permeability testing machine, and the thermal property measuring device. The system was verified with regard to data banking to confirm feasibility of the system to practical application. Among the cloth stabilizing technologies, discussions were given on age-based stability of cloth properties, repetitive transformation resistance, temperature, hardener deposition amount, and bending rigidity in cloths treated with temporary hardening agents. Discoloration, robustness and device damaging effect of cloths were also investigated. A partial and temporary hardening device was fabricated to make partial hardening possible. A continuous deflocculating device was also fabricated making deflocculation of temporarily hardened cloth possible. The deflocculation was discussed on the sewing process in relation with workability, and it was revealed that low-level hardening treatment is effective. It was verified that the handling is facilitated particularly in cloths that tend to curl. (NEDO)

This paper describes the sewing preparation and processing technology, extracted from the achievement report for fiscal 1985 on developing an automatic sewing system. The cloth property evaluation technology was discussed by using the KES testing machine, and the composite transformation, large bending and composite surface property measuring device. Multiple regression analysis was made on cloth properties required for operation of each sewing process, and the summary of cloth properties required for the sewing devices was identified. A case study was performed on the data banking system on the sewing machine operating process as the object. For the cloth stabilization technology, seven kinds of temporary hardening agents were selected, and given the performance test. Literatures were investigated on tolerance for human body exposure to working environment pollution. Fabrication of the continuously operating temporary hardener processing device achieved the performance as designed. Discussions were given on temporary hardener flow rate and supply pressure, particle diameters and rotation speed of the rotating disk, particle properties and hardening performance, and work uniformity, where the performance of the continuous temporary hardening treatment was verified. High level correlation was derived between the relative handling difficulty and the cloth properties. With regard to the hardening standard, discussions are required also on the correlation with sewability. (NEDO)

The objective of this study is to evaluate significant contributing factors affecting the functional prognosis of floating knee injuries using multivariate analysis. A total of 68 floating knee injuries (67 patients) were treated at Kitasato University Hospital from 1986 to 1999. Both the femoral fractures and the tibial fractures were managed surgically by various methods. The functional results of these injuries were evaluated using the grading system of Karlström and Olerud. Follow-up periods ranged from 2 to 19 years (mean 50.2 months) after the original injury. We defined satisfactory (S) outcomes as those cases with excellent or good results and unsatisfactory (US) outcomes as those cases with acceptable or poor results. Logistic regression analysis was used as a multivariate analysis, and the dependent variables were defined as a satisfactory outcome or as an unsatisfactory outcome. The explanatory variables were predicting factors influencing the functional outcome such as age at trauma, gender, severity of soft-tissue injury in the femur and the tibia, AO fracture grade in the femur and the tibia, Fraser type (type I or type II), Injury Severity Score (ISS), and fixation time after injury (less than 1 week or more than 1 week) in the femur and the tibia. The final functional results were as follows: 25 cases had excellent results, 15 cases good results, 16 cases acceptable results, and 12 cases poor results. The predictive logistic regression equation was as follows: Log 1-p/p = 3.12-1.52 x Fraser type - 1.65 x severity of soft-tissue injury in the tibia - 1.31 x fixation time after injury in the tibia - 0.821 x AO fracture grade in the tibia + 1.025 x fixation time after injury in the femur - 0.687 x AO fracture grade in the femur ( p=0.01). Among the variables, Fraser type and the severity of soft-tissue injury in the tibia were significantly related to the final result. The multivariate analysis showed that both the involvement of the knee joint and

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 conti...

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

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.

Factors affecting integration of midwifery nursing science theory with clinical practice in Vhembe District, Limpopo Province as perceived by professional midwives.

Science.gov (United States)

Malwela, Thivhulawi; Maputle, Sonto M; Lebese, Rachel T

2016-05-24

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. The aim of this study was to determine the factors affecting integration of midwifery nursing science theory with clinical practice as perceived by midwives. 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. 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. 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. 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.

Study of atmospheric emission trading programs in the United States

International Nuclear Information System (INIS)

1991-01-01

A detailed review and evaluation was conducted of federal and state atmospheric emission trading programs in the USA to identify the factors critical to a successful program. A preliminary assessment was also made of the feasibility of such a program for NOx and volatile organic compounds (VOC) in the lower Fraser Valley in British Columbia. To date, experience in the USA with atmospheric emissions trading has primarily involved trades of emission reduction credits pursuant to the 1977 Clean Air Act amendments. Most trades occur under netting provisions which allow expansion of an existing plant without triggering the stringent new-source review process. Six case studies of emissions trading are described from jurisdictions in California, New Jersey, and Kentucky and from the national SO 2 allowance trading program. Estimates of cost savings achieved by emissions trading are provided, and factors critical to a successful program are summarized. These factors include clearly defined goals, participation proportional to problem contribution, an emissions inventory of satisfactory quality, a comprehensive permit system, a credible enforcement threat, efficient and predictable administration, location of the program in an economic growth area, and support by those affected by the program. In the Fraser Valley, it is concluded that either an emissions reduction credit or an allowance trading system is feasible for both NOx and VOC, and recommendations are given for implementation of such a program based on the factors determined above. 1 fig., 8 tabs

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.

Geophysical investigations of the Seferihisar geothermal area, Western Anatolia, Turkey

Self-potential (SP), magnetic and very low frequency electromagnetic (EM-VLF) surveys were carried out in the Seferihisar geothermal area to identify major and minor fault zones and characterize the geothermal system. The SP study provided useful information on the local faults and subsurface fluid flow. The main SP anomalies appear mostly along and near active fault zones in the area of the Cumali, Tuzla and Doganbey hot springs. Two of these anomalies near the Tuzla hot springs were further evaluated by SP modelling. Total magnetic field values increase from the Doganbey to the Cumali hot springs. Modelling performed on the magnetic data indicates that between these two spring areas are four different regions or units that can be distinguished on the basis of their magnetic susceptibility values. Fraser filtering of EM-VLF data also indicates that there are three significant conductive zones in the regions around the Cumali, Tuzla and Doganbey hot springs, and that they lie between important fault systems. The EM-VLF and total (stacked) SP data show that the conductive tilt anomalies obtained by Fraser filtering generally coincide with negative SP areas. According to our geophysical investigations, new exploratory wells should be drilled into the conductive zones located between the Cumali and Tuzla hot springs. We further recommend that resistivity and magnetotelluric methods be carried out in the area to obtain additional information on the Seferihisar geothermal system. (author)

A cross-sectional analysis of perinatal depressive symptoms among Punjabi-speaking women: are they at risk?

Depression is the leading cause of disability for childbearing women. We examined three specific research questions among Punjabi-speaking women residing in the Fraser Health Authority: 1) What are the prevalence rates of prenatal depressive symptoms? 2) Do Punjabi-speaking women have a higher likelihood of reporting depressive symptoms compared to English-speaking women after controlling for age, level of education and financial worries, and 3) Given the same level of exposure to level of education and financial worries, do Punjabi-speaking women have the same likelihood of reporting depressive symptoms? Data originated from the Fraser Health Authority prenatal registration database consisting of pregnant women (n = 9684) who completed a prenatal registration form between June 2009 and August 2010; 9.1 % indicated speaking Punjabi. The Whooley Depression Screen measured depressive symptoms. Chi-square tests and logistic multiple regression were used to examine the rates of reporting depressive symptoms among Punjabi-speaking women compared to English-speaking women. Punjabi-speaking women are at a higher risk for perinatal depressive symptoms. Women needing an interpreter were more likely to report prenatal depressive symptoms compared to English-speaking women. All registrants who reported financial worries had four and a half times the odds of reporting depressive symptoms. The impact of financial worries was significantly greater in the English-speaking women compared to the Punjabi-speaking women needing an interpreter. Using an established screening device, Punjabi-speaking women were found to be at higher risk for prenatal depressive symptoms.

Surface current measurements in Juan de Fuca Strait using the SeaSonde HF [high frequency] radar

International Nuclear Information System (INIS)

Hodgins, D.O.

1994-09-01

The shore-based SeaSonde high-frequency (HF) radar was deployed for three weeks in summer 1993 to measure surface currents in the Strait of Georgia, British Columbia. Experimental objectives included documenting the complex flow regime generated by large tides and the brackish plume of the Fraser River, and determining the radar performance under low-wind, low-salinity conditions. The radar data showed that surface flows are dominated by the plume jet formed by the Fraser River outflow, giving rise to recurring, energetic eddies with scales of 8-12 km, strong flow meanders, and convergent fronts. These features were continuously modulated by the along-channel tidal flows. Comparisons with a detailed numerical model hindcast gave good correlation between observed and predicted flow fields, especially at tidal and low frequencies. Radar return was found to be correlated with local winds and radar performance was independent of salinity variations in the plume. Synthetic aperture radar (SAR) provides a map of the radar scattering characteristics of the ocean surface on a capillary wave scale. ERS-1 satellite and airborne SAR images for July 28, 1993 were obtained and surface features were examined in the context of the HF radar current fields. Results show that SAR images alone cannot reliably provide the dynamical data required in this region by oil spill models. Under certain conditions, however, the radar imagery offers valuable physical information on phenomena affecting oil slick development. Interpretation of SAR imagery in conjunction with other remote sensing information would offer more quantitative prediction data. 28 refs., 334 figs., 1 tab

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.

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.

Full Text Available L'examen du rapport entre race et démocratie au Brésil demande une approche théorique particulière partant des différentes conceptions de la reconnaissance. 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.

Towards a critical theory of information

Directory of Open Access Journals (Sweden)

Christian Fuchs

2009-11-01

The debate on redistribution and recognition between critical theorists Nancy Fraser and Axel Honneth gives the opportunity to renew the discussion of the relationship of base and superstructure in critical social theory. Critical information theory needs to be aware of economic, political, and cultural demands that it needs to make in struggles for ending domination and oppression, and of the unifying role that the economy and class play in these demands and struggles. Objective and subjective information concepts are based on the underlying worldview of reification. Reification endangers human existence. Information as process and relation enables political and ethical alternatives that have radical implications for society.

An institute for the training of radiochemist was proposed in 1989 by scientists/educators from Simon Fraser University (SFU) and the TRIUMF Nuclear Research Facility in Canada. The intensive program spans 6 weeks and includes seminars and problem sessions as well as practical laboratory experience. Topics include health physics, synthesis of short lived radiopharmaceuticals, automation and quality control. The first offering was in May-June 1990. Based on this experience a textbook on Radiochemistry and Radiopharmaceutical Chemistry has been initiated. Parts of the program may be implemented into a credit course to be offered through the Department of Chemistry at SFU. (author) 6 refs.; 3 tabs

The principles of teratology: are they still true?

Science.gov (United States)

Friedman, Jan M

2010-10-01

James Wilson originally proposed a set of "Principles of Teratology" in 1959, the year before he helped to found the Teratology Society. By 1977, when these Principles were presented in a more definitive form in Wilson and Fraser's Handbook of Teratology, they had become a standard formulation of the basic tenets of the field. Wilson's Principles have continued to guide scientific research in teratology, and they are widely used in teaching. Recent advances in our knowledge of the molecular and cellular bases of embryogenesis serve only to provide a deeper understanding of the fundamental developmental mechanisms that underlie Wilson's Principles of Teratology. © 2010 Wiley-Liss, Inc.

Political Ideology and Economic Freedom across Canadian Provinces

DEFF Research Database (Denmark)

Bjørnskov, Christian; Potrafke, Niklas

This paper examines how political ideology influenced economic freedom in the Canadian provinces. We analyze the dataset of economic freedom indicators compiled by the Fraser Institute in 10 Canadian provinces over the 1981-2005 period and introduce two different indices of political ideology......: government and parliament ideology. The results suggest that government ideology influenced labor market reforms: market-oriented governments promoted liberalization of the labor market. Parliamentary ideology did not influence economic liberalization at all. This finding (1) identifies differences between...... leftist and rightwing governments concerning the role of government in the economy and (2) indicates that ideological polarization concerns governments but less parliamentary fractions in the Canadian provinces. ...

Anophthalmia is the congenital absence of ocular tissue from the orbit. Many syndromes and malformations (e.g., anophthalmia-esophageal-genital syndrome, Matthew-Wood syndrome, CHARGE syndrome, oculo-facial-cardio-dental-syndome, heterotaxy, and Fraser syndrome) have been associated with anophthalmia. However, its relation with congenital heart disease has not been fully elucidated. In this article, we discuss two cases of patients with anophthalmia and congenital heart defects, and we compare these findings with other syndromes with which anophthalmia has been associated. One of our two patients showed complex congenital heart disease with heterotaxia, polysplenia, and normal lung lobation. These findings may reflect a new dimension of anophthalmia, heterotaxia, and congenital heart disease associations.

Similarity of nutrient uptake and root dimensions of Engelmann spruce and subalpine fir at two contrasting sites in Colorado

Energy Technology Data Exchange (ETDEWEB)

2009-10-09

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

The research and development project for automatic sewing systems is aimed at establishing the techniques necessary for developing (automatic sewing systems) which efficiently produce diversified types of products in small quantities, to cope with various requirements, e.g., diversified consumers' needs and reduced cycle periods. This project covers R and D of the sewing preparation/processing, sewing/assembling, cloth handling, and system management/control techniques. The program for developing the total systems and elementary techniques draws the conceptual designs of their functions, performance and shapes, to outline the overall R and D project. The programs for the individual elementary techniques include studies on their basic functions and performance; design works from the basic designs to determine the specifications to the detailed designs of the devices to be developed; construction of the test units on a trial basis; and function confirming tests to confirm operability of the unit components and device performance, where these works are simultaneously implemented. This paper describes the interim results of evaluation of the elements developed for the elementary techniques, summarizing the results obtained so far. It is concluded that most of the targets of the R and D themes are sufficiently achieved by the end of FY 1987, and that the project can be now advanced to the next phase, construction of the test plants.

The vibration method is usually utilized on the measurement of cable tension during construction of cable bridge such as Nielsen bridges or cable stayed bridges. Practical formula for the vibration method previously proposed by authors is often used where bending rigidity is taken into account. These formula, however, have a certain limit of application and do not yield good results when the cable is not slender or not enough mentioned. The practical formula is modified to improve the accuracy and new formulas are made. The new practical formulas are applicable to any cables, regardless of its length and tension in it. The accuracy is confirmed through comparison of the value obtained by practical formulas with measured values and calculated value by F.E.M. 2 refs., 4 figs., 1 tab.

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.

Web-based surveys as an alternative to traditional mail methods.

Environmental economists have long used surveys to gather information about people's preferences. A recent innovation in survey methodology has been the advent of web-based surveys. While the Internet appears to offer a promising alternative to conventional survey administration modes, concerns exist over potential sampling biases associated with web-based surveys and the effect these may have on valuation estimates. This paper compares results obtained from a travel cost questionnaire of visitors to Fraser Island, Australia, that was conducted using two alternate survey administration modes; conventional mail and web-based. It is found that response rates and the socio-demographic make-up of respondents to the two survey modes are not statistically different. Moreover, both modes yield similar consumer surplus estimates.

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

Traditional microwave observation of snowpack includes brightness temperature and backscatter. The single baseline configuration and loss of phase information hinders the retrieval of snow stratigraphy information from microwave observations. In this paper, we are investigating the tomography of polarimetric SAR to measure snow stratigraphy. In the past two years, we have developed a homodyne frequency modulated continuous wave radar (FMCW), operation at three earth exploration satellite bands within the X-band and Ku-band spectrums (centered at 9.6 GHz, 13.5 GHz, and 17.2 GHz) at Jet Propulsion Laboratory. The transceiver is mounted to a dual-axis planar scanner (60cm in each direction), which translates the antenna beams across the target area creating a tomographic baseline in two directions. Dual-antenna architecture was implemented to improve the isolation between the transmitter and receiver. This technique offers a 50 dB improvement in signal-to-noise ratio versus conventional single-antenna FMCW radar systems. With current setting, we could have around 30cm vertical resolution. The system was deployed on a ground based tower at the Fraser Experimental Forest (FEF) Headquarters, near Fraser, CO, USA (39.847°N, 105.912°W) from February 1 to April 30, 2017 and run continuously with some gaps for required optional supports. FEF is a 93-km2 research watershed in the heart of the central Rocky Mountains approximately 80-km West of Denver. During the campaign, in situ measurements of snow depth and other snowpack properties were performed every week for comparison with the remotely sensed data. A network of soil moisture sensors, time-lapse cameras, acoustic depth sensors, laser depth sensor and meteorological instruments was installed next to the site to collect in situ measurements of snow, weather, and soil conditions. Preliminary tomographic processing of ground based SAR data of snowpack at X- and Ku- band has revealed the presence of multiple layers within

Sensible and latent heat and mass fluxes from the snow surface are modulated by site canopy density and structure. Forest and shrub canopies reduce wind speeds and alter the radiation and thermal environment which will alter the below canopy energetics that control the magnitude of turbulent fluxes between the snow surface and the atmosphere. In this study eddy covariance (EC) systems were located in three experimental catchments along a mountain transect through the North American Cordillera. Within each catchment, a variety of sites representing the local range of climate, weather, and canopy conditions were selected for measurement of sensible and latent heat and mass flux from the snow surface. EC measurements were made 1) below a uniform pine canopy (2745m) in the Fraser Experimental Forest in Colorado from February through June melt-out in 2003; 2) at an open, unforested site (2100m), and below an Aspen canopy (2055m) within a small headwater catchment in the Reynolds Creek Experimental Watershed, Owyhee Mts., Idaho from October, 2003, through June melt-out, 2004; and 3) at five sites, representing a range of conditions: a) below a dense spruce forest (750m); b) a north-facing shrub-tundra slope (1383m); c) a south-facing shrub-tundra slope; d) the valley bottom between b) and c) (1363m); and e) a tundra site (1402m) in the Wolf Creek Research Basin (WCRB) in the Yukon, Canada during the 2001 and 2002 snow seasons. Summary data from all sites are presented and compared including the relative significance of sublimation losses at each site, the importance of interception losses to the snowcover mass balance, and the occurrence of condensation events. Site and weather conditions that inhibit or enhance flux from the snow surface are discussed. This research will improve snow modeling by allowing better representation of turbulent fluxes from snow in forested regions, and improved simulation of the snowcover mass balance over low deposition, high latitude sites

Geomechanical effects of stress shadow created by large-scale destress blasting

Directory of Open Access Journals (Sweden)

Isaac Vennes

2017-12-01

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.

Remote sensing of surface currents in the Fraser River plume with the SeaSonde HF radar

1994-09-01

The SeaSonde 12.5-MHz radar system was deployed to measure surface currents in the Juan de Fuca Strait in July 1992. Reliable data were obtained from the two radars installed, and successful trials were conducted with the Infosat satellite link to transmit data from the remote site. Data recovery from the SeaSonde was generally good, with maximum ranges varying from 15 km to over 30 km. Sea echo return strength at both radars was correlated with wind, consistent with lower Bragg scattering at lower wind speeds. A simple surface current forecasting algorithm, based on decomposing the signal into tidal and residual bands, was examined. It was found that tides account for the greatest portion of currents in the study area, and could be forecasted out to 48 h with 1-2 d of input data. The nonpredictable, fluctuating part of the current signal was isolated and its statistics were calculated. The algorithm tests showed that the SeaSonde data can be used to measure and predict the slowly varying tidal and mean flow velocities, as well as the random part of the signal, both of which are important in oil spill modelling. Surface flow patterns and time-series data from the SeaSonde measurements, and from a three-dimensional hydrodynamic model, were compared from an oil spill modelling perspective. In general, surface flow patterns from the model were smoother than those observed. The differences were most noticeable in the cross-channel direction. The radar data indicate that a flow-dependent eddy viscosity formulation, with coefficients calibrated to reproduce the features observed with the radar, would improve agreement and yield a good model for data assimilation. 21 refs., 478 figs., 3 tabs

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.

Rural science education as social justice

What part can science education play in the dismantling of obstacles to social justice in rural places? In this Forum contribution, I use "Learning in and about Rural Places: Connections and Tensions Between Students' Everyday Experiences and Environmental Quality Issues in their Community"(Zimmerman and Weible 2016) to explicitly position rural education as a project of social justice that seeks full participatory parity for rural citizens. Fraser's (2009) conceptualization of social justice in rural education requires attention to the just distribution of resources, the recognition of the inherent capacities of rural people, and the right to equal participation in democratic processes that lead to opportunities to make decisions affecting local, regional, and global lives. This Forum piece considers the potential of place-based science education to contribute to this project.

A comprehensive evaluation is made upon completion of the automatic sewing system research and development project. The project aims to achieve a 50% increase in productivity through effective use of a multiple-product/small-amount production scheme in small and medium sewing industries. The intelligent cloth inspecting machine (prior to sewing) in a laser-aided cutting system is as competent as the currently used sewing mill inspection system, and the resultant data are effectively utilized in the cutting process. As for the cutter, it is demonstrated that it is more than two times higher in cutting speed than a currently used laser cutting system; that it is sufficiently accurate in avoiding parts with flaws and in pattern matching; and that it is reliable in complying with process information provided. As for the flexible sewing system, it is acknowledged that it correctly recognizes information attached to cut parts and that it joins them with flexibility in response to changes in the material, pattern, or size. As for the high-technology assembling system, satisfaction is found in its automated 3-dimensional sewing of parts received from the previous stage and in its flow of production. As for the 3-dimensional flexible press, the quality after finish is found satisfying. The said systems are integratedly operated, and it is found that the goal of the research and development has been achieved. (NEDO)

Herpes simplex virus-specific DNA sequences have been detected by Southern hybridization analysis in both central and peripheral nervous system tissues of latently infected mice. We have detected virus-specific sequences corresponding to the junction fragment but not the genomic termini, an observation first made by Rock and Fraser (Nature [London] 302:523-525, 1983). This "endless" herpes simplex virus DNA is both qualitatively and quantitatively stable in mouse neural tissue analyzed over a 4-month period. In addition, examination of DNA extracted from human trigeminal ganglia has shown herpes simplex virus DNA to be present in an "endless" form similar to that found in the mouse model system. Further restriction enzyme analysis of latently infected mouse brainstem and human trigeminal DNA has shown that this "endless" herpes simplex virus DNA is present in all four isomeric configurations.

Interdisciplinarity, a New Generation of Architects, and Mediocritas

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.

Green thunderstorms

Science.gov (United States)

Gallagher, Frank Woolsey, III

Many people around the world have observed green light apparently emanating from severe thunderstorms, but until recently there has been no scientific study of the phenomenon. Green thunderstorms have been observed from time to time in association with deep convection or severe weather events. Some skeptics who have not personally observed a green thunderstorm suggest that they are some kind of illusion. The existence of green thunderstorms has been objectively demonstrated by recording spectra of light from thunderstorms using a handheld spectrophotometer. During the spring and summer of 1995 and the spring of 1996 numerous storms were observed and spectra of the light emanating from these storms were recorded. Observations were made both at the ground and aboard research aircraft. Furthermore, time series of spectra were recorded as the observed color of some storms changed from dark blue to a bluish-green. Several hypotheses have been advanced to explain the occurrence of green light in connection with severe storms. Fankhauser gave some observational support to the belief that green light from thunderstorms is possible and believed that the source of the light is from the blue sky penetrating thin regions in the clouds. Fraser believes that light from the setting sun, in combination with the process of scattering by atmospheric molecules, creates the green light associated with severe weather and the thunderstorm acts only as a black backdrop. Unfortunately, no cloud illuminated by the sun is black and the green airlight produced by the Fraser theory is in reality overwhelmed by light reflected by the cloud. Often the unusual coloration has been attributed to hail or to reflection of light from foliage on the ground. The quantitative measurements made during the observation period fail to support these assumptions. We have observed thunderstorms to be green over ground that was not green and we have observed blue thunderstorms over ground that was green

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

Science.gov (United States)

Holobinko, Anastasia; Kemp, Helen; Meier-Augenstein, Wolfram; Prowse, Tracy; Ford, Susan

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.

Controls on the abruptness of gravel-sand transitions

Venditti, J. G.; Church, M. A.; Lamb, M. P.; Domarad, N.; Rennie, C. D.

As gravel-bedded rivers fine downstream, they characteristically exhibit an abrupt transition from gravel- to sand-bed. This is the only abrupt transition in grain-size that occurs in the fluvial system and has attracted considerable attention. A number of competing theories have been proposed to account for the abruptness of the transition, including base-level control, attrition of ~10mm gravel to produce sand, and sediment sorting processes. The prevailing theory for the emergence of abrupt transitions is size selective sorting of bimodal sediment wherein gravel deposits due to downstream declining shear stress, fining the bedload until a sand-bed emerges. We explored this hypothesis by examining grain-size, shear stress, gravel mobility and sand suspension thresholds through the gravel-sand transition (GST) of the Fraser River, British Columbia. The Fraser GST is an arrested gravel wedge with patches of gravel downstream of the wedge forming a diffuse extension. There is an abrupt change in bed slope through the transition that leads to an abrupt change in shear stress. The GST, bed-slope change and backwater caused by the ocean are all coincident spatially, which enhances the sharpness of the GST. Interestingly, the bimodal reach of the river occurs downstream of the GST and exhibits no downstream gradients in shear stress, suspended sediment flux, gravel mobility or sand suspension thresholds. This calls into question the prevailing theory for the emergence of an abrupt GST by size selective sorting. We provide evidence, both empirical and theoretical, that suggests the emergence of an abrupt GST is caused by rapid deposition of sand when fine gravel deposits. We argue that the emergence of gravel-sand transitions is a consequence of gravel-bedded rivers adopting a steeper slope than sand-bedded rivers. The abruptness arises because the bed slope required to convey the gravel load fixes the distal location of a terminal gravel wedge, and once the river has

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.

The Hudson's Bay Company as a context for science in the Columbia Department.

Schefke, Brian

2008-01-01

This article aims to elucidate and analyze the links between science, specifically natural history, and the imperialist project in what is now the northwestern United States and western Canada. Imperialism in this region found its expression through institutions such as the Hudson's Bay Company (HBC). I examine the activities of naturalists such as David Douglas and William Tolmie Fraser in the context of the fur trade in the Columbia Department. Here I show how natural history aided Britain in achieving its economic and political goals in the region. The key to this interpretation is to extend the role of the HBC as an imperial factor to encompass its role as a patron for natural history. This gives a better understanding of the ways in which imperialism--construed as mercantile, rather than military--delineated research priorities and activities of the naturalists who worked in the Columbia Department.

The automatic sewing system technique research association has been commissioned by the Agency of Industrial Science and Technology for (research and development of automatic sewing systems). This program covers R and D of the elementary techniques for total systems and sewing preparation/processing, sewing/assembling, cloth handling, and system management/control. The total system is designed and studied, and automation of the production systems is studied, in order to reduce time for producing unit quantity of diversified types of clothes in small quantities at least by 50% from the current level. The test plant is designed, constructed and operated, to evaluate and confirm its functions for the above purposes. In the FY 1982, the conceptual designs are drawn to establish the overall production systems for producing diversified types of clothes in small quantities. The program for the sewing preparation/processing evaluates various characteristics of cloth to be processed by the sewing system, based on which the cloth characteristics evaluation, cloth stabilization, high-function pattern preparation, and cloth measuring/unfolding/cutting techniques are studied to establish the automatic cloth unfolding/cutting techniques. The FY 1982 efforts are directed to the conceptual designs. (NEDO)

A comprehensive evaluation is made upon completion of the automatic sewing system research and development project. The project aims to achieve a 50% increase in productivity through effective use of a multiple-product/small-amount production scheme in small and medium sewing industries. The intelligent cloth inspecting machine (prior to sewing) in a laser-aided cutting system is as competent as the currently used sewing mill inspection system, and the resultant data are effectively utilized in the cutting process. As for the cutter, it is demonstrated that it is more than two times higher in cutting speed than a currently used laser cutting system; that it is sufficiently accurate in avoiding parts with flaws and in pattern matching; and that it is reliable in complying with process information provided. As for the flexible sewing system, it is acknowledged that it correctly recognizes information attached to cut parts and that it joins them with flexibility in response to changes in the material, pattern, or size. As for the high-technology assembling system, satisfaction is found in its automated 3-dimensional sewing of parts received from the previous stage and in its flow of production. As for the 3-dimensional flexible press, the quality after finish is found satisfying. The said systems are integratedly operated, and it is found that the goal of the research and development has been achieved. (NEDO)

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..

TRIUMF the home of Canadian subatomic physics

CERN Document Server

Poutissou, J M; Gillies, James D

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.

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.

Achieving Citizenship and Recognition through Blogging about Homelessness

Directory of Open Access Journals (Sweden)

Barbara Schneider

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.

O que as teorias do reconhecimento têm a dizer sobre as manifestações de rua em 2013 no Brasil

Directory of Open Access Journals (Sweden)

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.

Cognitive deterioration from long-term abuse of dextromethorphan: a case report.

Dextromethorphan (DM), the dextrorotatory isomer of 3-hydroxy-N-methylmorphinan, is the main ingredient in a number of widely available, over-the-counter antitussives. Initial studies (Bornstein 1968) showed that it possessed no respiratory suppressant effects and no addiction liability. Subsequently, however, several articles reporting abuse of this drug have appeared in the literature. The drug is known to cause a variety of acute toxic effects, ranging from nausea, restlessness, insomnia, ataxia, slurred speech and nystagmus to mood changes, perceptual alterations, inattention, disorientation and aggressive behavior (Rammer et al 1988; Katona and Watson 1986; Isbell and Fraser 1953; Devlin et al 1985; McCarthy 1971; Dodds and Revai 1967; Degkwitz 1964; Hildebrand et al 1989). There have also been two reported fatalities from DM overdoses (Fleming 1986). However, there are no reports describing the effects of chronic abuse. This report describes a case of cognitive deterioration resulting from prolonged use of DM. PMID:7803371

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 This paper tries to open a debate about teaching knowledge avai­lable today in the university, showing a plurality of learning practices developed in it, some of which have become, whereas others proposals are ignored or hidden. To account for the analysis about teaching university, our methodology take it some experts have described like traditions of teacher education: the academic tra­dition, the technological tradition, the practice tradition, the personalist-humanist tradition, the critic/poscritic tradition. From these, we use two hermeneutics propo­sals: the paradigms of teacher education from Kenneth Zeichner, the hermeneutical strategies used by Nancy Fraser to discuss social policies. At the end, this paper defended the need to thinking about our practices as teachers, so that the analysis of discourse on the university teaching, our identification with them or not, and the subsequent debate, may emerging processes of professional development and teaching innovation.

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. The findings of the Fox report are reproduced in full. (U.K.)

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

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

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

Directory of Open Access Journals (Sweden)

Kazuyuki Aihara

2011-04-01

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.

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.

Sandmining - government rules confuse industry

International Nuclear Information System (INIS)

Grayson, R.

1989-01-01

Australia is the world's largest supplier of the mineral sands rutile, ilmenite, zircon and monazite. A combined total of two million tonnes are mined annually, most of which is exported. Western Australia accounts for about 75% of Australia's mineral sands production, worth about $343 million. The remainder is mined along an eastern coastal strip between the New South Wales central coast and Fraser Island in southern Queensland where there has been a revival of past controversies over environmental and radiation concerns. The NSW Government has approved a proposal by Australmin Holdings to mine mineral sands at Newrybar on the far north coast. It has also issued draft guidelines which will exclude sand mining from national parks, nature reserves, sites designated as coastal wetlands and littoral rainforest, beaches and frontal dunes. These guidelines which miners say will make about 50% of east coast reserves, an estimated $6 billion worth of mineral sands untouchable, have been attacked by the mining industry which argues that sand mining and environmental protection are not incompatible and which warns of a loss of economic opportunities for NSW

Leaf gas exchange of understory spruce-fir saplings in relict cloud forests, southern Appalachian Mountains, USA

Global climate change is expected to increase regional cloud ceiling levels in many mountainous forested areas of the world. This study investigated environmental influences on the gas exchange physiology of understory red spruce and Fraser fir trees at 2 sites in the Appalachian mountains. The study hypothesized that the humid, cloudy environment would influence the photosynthetic performance of the trees, and that the species would adapt to low, diffuse light. The study also predicted that leaf conductance to carbon dioxide (CO{sub 2}) would be high as a result of low leaf-to-air-vapour pressure deficit (LAVD). The study demonstrated that leaf conductance decreased exponentially as LAVD increased. Predawn leaf water potentials remained stable, while late afternoon values declined. It was concluded that leaf gas exchange was correlated with the response of leaf conductance and LAVD. The cloudy, humid environment strongly influenced tree leaf gas exchange and water relations. It was suggested that further research is needed to investigate cloud impacts on carbon gain and water relations. 72 refs., 1 tab., 8 figs.

Pacific Gateway: State Surveillance and Interdiction of Criminal Activity on Vancouver’s Waterfront

Chris Madsen

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.

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

Coyle, Thomas R; Rindermann, Heiner; Hancock, Dale

2016-10-01

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.

Making the connection: The B.C. Hydro electric system and how it is operated

1993-01-01

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

The Impact of the Economic Transition on the Development of Economic Freedom – Case of Poland

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.

Composite indicators of labour market regulations in a comparative perspective

Mariya Aleksynska

2016-02-01

Full Text Available Abstract Technological progress and the internet brought about new possibilities of creating, storing, exchanging, replicating, and using various kinds of data for research. This paper discusses some of the dangers embedded into the reuse of data produced by some institutions by other institutions through the combination and aggregation of initial data into various data products. To this end, we use an example of labour market regulations’ indicators developed by the World Economic Forum, the International Institute for Management Development (IMD, and the Fraser Institute, which are all partly based on the World Bank Employing Workers Indicator. We document how these three indicators compare and identify both their common and specific limitations. For each of these indicators, the choice of subcomponents and of aggregate techniques results in different pictures of labour market regulations, despite the use of the overlapping initial sources of data. Our comparative exercise calls for continuous efforts to improve the indicators of labour market regulations, as well as for cautious use of such indicators for research and policy advice.

Some possible correlations between electro-magnetic emission and seismic activity during West Bohemia 2008 earthquake swarm

P. Kolář

2010-10-01

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.

) 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.

Precarity in the Brussels-Capital Region: The Issues at Stake for Public Policy in Response to the Precarization of Single-parent Families in Brussels

Directory of Open Access Journals (Sweden)

Martin Wagener

2015-12-01

Full Text Available The process of precarization is analysed in different manners in most literature concerning contemporary stakes of western welfare states. In comparison to other countries, Belgium has known a rather specific and delimited effect of the economic crisis from 2008, but certain groups face rather an ongoing effect of precarization on multiple and intertwined aspects. The aim of the article is to analyse the situation of precarity of single-parent families in the Brussels-Capital Region. The attention to that group is related to its higher risk of precarity and poverty. Furthermore it allows analysing the limits of public policies in the fight against poverty and precarity, that are clearly inadequate. Various options in terms of public policies and legal measures in the fight against poverty are discussed from three different angles of perspective: socioeconomic positions, social integration and the subjective experience (Dubet 1994. The tension between recognition and redistribution measures is central (Fraser 2011 in the argumentation for a balanced vision of policy measures to address single-parent poverty. La literatura científica sobre las apuestas contemporáneas de los estados de bienestar occidentales analiza de forma diferente el proceso de precarización. En comparación con otros países, Bélgica ha vivido desde 2008 un efecto de la crisis económica bastante específico y delimitado. Sin embargo, algunos grupos se enfrentan a un proceso de precarización continuo en numerosos aspectos, interrelacionados entre sí. El objetivo de este artículo es analizar la situación de precariedad de las familias monoparentales de la región de Bruselas capital.

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.

Inclusion and Participation: Working with the Tensions

Directory of Open Access Journals (Sweden)

Gideon Calder

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.

Identity, recognition and redistribution: a critical analysis of Charles Taylor, Axel Honneth and Nancy Fraser’s theories

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.

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

Science.gov (United States)

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.

Universal and local time components in Schumann resonance intensity

2008-05-01

Full Text Available We extend the technique suggested by Sentman and Fraser (1991 and discussed by Pechony and Price (2006, the technique for separating the local and universal time variations in the Schumann resonance intensity. Initially, we simulate the resonance oscillations in a uniform Earth-ionosphere cavity with the distribution of lightning strokes based on the OTD satellite data. Different field components were used in the Dayside source model for the Moshiri (Japan, geographic coordinates: 44.365° N, 142.24° E and Lehta (Karelia, Russia, 64.427° N, 33.974° E observatories. We use the extended Fourier series for obtaining the modulating functions. Simulations show that the algorithm evaluates the impact of the source proximity in the resonance intensity. Our major goal was in estimating the universal alteration factors, which reflect changes in the global thunderstorm activity. It was achieved by compensating the local factors present in the initial data. The technique is introduced with the model Schumann resonance data and afterwards we use the long-term experimental records at the above sites for obtaining the diurnal/monthly variations of the global thunderstorms.

Foucault on methadone: beyond biopower.

Science.gov (United States)

Keane, Helen

2009-09-01

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.

New technologies for large-scale micropatterning of functional nanocomposite polymers

Science.gov (United States)

Khosla, A.; Gray, B. L.

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.

Sea state indices for a coastal strait

Gemmrich, Johannes; Dewey, Richard

2017-04-01

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.

Teaching an Invisible Subject: How are we Educating Faculty about Copyright?

Directory of Open Access Journals (Sweden)

Jennifer Zerkee

2018-02-01

Full Text Available Copyright can be an invisible issue for instructors because infringement or improper use of copyright-protected material will not impede teaching. Copyright law is nuanced and open to interpretation; it is not always clear whether a particular action is compliant or not. This poster will share the results of the presenter’s Canada-wide survey of university copyright administrators, exploring institutions’ provision of copyright education to instructors. The presenter found more questions rather than answers as a result of the survey. Most respondents do no assessment of their copyright instruction, and instead are comfortable relying on experience, questions from faculty, and anecdotal evidence to form an impression of instructors’ familiarity with copyright rules. Is informal appraisal adequate for ensuring that libraries and copyright offices are fulfilling their responsibility to encourage and enable the confident and lawful use of copyright-protected material? What other evidence could be gathered to inform copyright administrators’ efforts? This poster will encourage participants to think about copyright education at their institutions, will share the results of the survey, including approaches being taken by universities across Canada, and will share Simon Fraser University's approaches to instructor education

Lost in translation? Rethinking First Nation education via LUCID insights

Nielsen, Thomas William

2010-10-01

This paper reports on findings from the Learning for Understanding through Culturally-Inclusive Imaginative Development project (LUCID). LUCID has been a 5-year (2004-2009) research and implementation endeavour and a partnership between Simon Fraser University (SFU) and three districts in British Columbia, Canada. Via emotionally engaging pedagogies and a culturally-inclusive curriculum, the project aimed at improving students' educational experience, particularly First Nations learners. Using a combination of Actor Network Theory (Latour, 2005, in: Reassembling the social: an introduction to Actor-Network Theory, Oxford University Press, Oxford) and Hermeneutic Phenomenology (Van Manen, 1990, in: Researching lived experience, The State University of New York, New York), site visits and interview data were examined with reference to the (f)actors influencing project objectives. Although each school district was unique, shared themes included: the importance of creating a community with shared intent; the role of executives as potential "change agents"; the problematic nature of emotionally-engaging teaching; and the complex influences of cultural and historical trauma. The latter theme is explored in particular, presenting the argument that language deficiency and a consequent lack of autonomy might be at the root of many problems experienced in First Nations communities.

Use of ERTS-1 pictures in coastal oceanography in British Columbia

Science.gov (United States)

Gower, J. F. R.

1973-01-01

The ERTS-1 color composite picture of the Vancouver-Victoria region illustrates the value of ERTS data for coastal oceanography. The water of the Fraser River plume which is so clearly visible in the center of the scene has been of interest to oceanographers on the west coast of Canada for a long time as an easily visible tracer of surface water circulation in the strait of Georgia. Maps of the plume at different states of the tide and with different river flow and weather were compiled from oblique aerial photographs in 1950 and used in the siting of sewage and other outfalls in the Vancouver area. More recently high level aerial photomosaics have been used to map the plume area, but the plume can spread over distances of 30 to 40 miles and many photographs, with the uneven illumination inherent in wide angle coverage, are needed for the mosaic. The ERTS satellite gives the first complete view of the plume area. Electronic enhancement of the images shows that the satellite's narrow angle coverage allows very weak surface turbidity features to be made visible to give information on surface currents over a wide area.

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

Sullivan, J.H.; Teramura, A.H.

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

Resistivity distribution in underground indicates anomaly in some cases due to volcanic activity, airborne VLF survey of Izu-Oshima volcano in whole area was carried out by measurement of the anomalous vertical magnetic field. The flight direction was determined with reference to both of the transmitter direction of the VLF waves and the running direction of the geologic formation. The flight altitude and the flight lines spacing were 100 m and 200 m respectively. Typical profiles of four lines of measurement were investigated. The resistivity anomalies were indicated corresponding to the position of known geologic fissure line, the lip of the caldera, the line of the craters and side volcanos. Several anomalous trends were detected by the contour drawing of the Fraser filter output. The detected results were as follow: new volcanos with the resistivity anomaly, the resistivity anomalies spread to the north-northwest from Goshinka jaya, the anomalies due to flowed lava, the anomalies by encroached water from the caldera wall, the effects from side volcanoes and so on. The resistivity anomalies by airborne VLF survey correspond to the known volcanic activities, and they are useful for elucidation of the underground volcanism. (6 figs, 4 refs)

This program covers R and D of the elementary techniques for total systems and sewing preparation/processing, sewing/assembling, cloth handling, and system management/control. This report describes the results of the R and D efforts for the total systems. For producing diversified products in small quantities, which is the object of this R and D program, the target is set to reduce processing time by at least 50% from the current level. The efforts to achieve this target by solving the problems involved therein are made from the side of developing FMS and FA procedures, and apparel side. The program for the former investigates the required functions of individual sub-systems that constitute the total system, to clarify the technical targets of the core elementary techniques for each sub-system. The program for the latter analyzes the sewing steps for producing diversified clothes types, specifications for automatic operation, integration, standardization and coding of the steps, and so on, based on the results of studies on basic apparel types.

Le service sexuel comme « service artistique » : la dissolution du sexe pour une éthique minimale du travail du sexe

En 2003, l’artiste en art conceptuel et performeuse américaine, Andrea Fraser, commettra l’impensable de « coucher » avec un collectionneur afin de critiquer le milieu et surtout le marché de l’art contemporain. L’article qui suit propose une analyse thématique de l’aspect sexuel et éthique de cette oeuvre intitulée Untitled. Il sera d’abord question des significations possibles de cette performance et ses questionnements artistiques plus autoréférentiels. Je compte ensuite aborder plus précisément la position trouble de la subjectivité de l’artiste qui oscille entre une posture d’objet sexuel et d’artiste. De même, le texte fera état de la position novatrice que l’oeuvre présente sur les enjeux éthiques du travail du sexe en déconstruisant les arguments paternalistes généralement invoqués pour criminaliser le travail du sexe. Et finalement, j’aborderai la question de savoir comment la nature sexuelle de l’oeuvre vient désacraliser à la fois l’art et la sexualité, et par le fait même critiquer l’idée que la sexualité soit le siège de la subjectivité. En désacralisant ainsi la sexualité, je postule qu’Untitled offre la possibilité de concevoir le travail du sexe de manière plus neutre.How can a sexual act in exchange of money with an art collector be offered as a work of art?

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.

Cordilleran Ice Sheet (CIS) delivered meltwater to the NE Pacific Ocean off BC and WA via glacial lake outburst floods (GLOFs), ice rafting and subglacial meltwater discharge. A deglacial glaciomarine sedimentation record is preserved in the well dated ~50-kyr core MD02-2496 (48˚58.47' N, 127˚02.14' W, water depth 1243 m), collected off Vancouver Island. To understand the history of the relationship between the CIS, climate and meltwater discharge, high resolution, multi-proxy geochemical records from the interval that captures the Fraser Glaciation (~30-10 ka) were generated. These proxies include Mg/Ca temperatures and δ18Oseawater from planktonic foraminiferal sp. N. pachyderma and G. bulloides, elemental and organic carbon (Corg) geochemistry of bulk sediments, ɛNd and K/Ar dating of the rose by > 3°C to 10-12°C in association with an additional IRD event at ~14.8 ka sourced from a ~75 Ma felsic volcanic source, likely the Southern Coast Plutonic Complex. At no point in the δ18Oseawater reconstruction is an obvious meltwater isotopic signature recorded despite the sedimentary evidence for both ice rafting and outburst flooding. Thus CIS meltwater likely entered the NE Pacific Ocean via hyperpycnal flow.

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.

Kinetic Analysis of Recovery, Recrystallization, and Phase Precipitation in an Al-Fe-Si Alloy Using JMAEK and Sesták-Berggren Models

Science.gov (United States)

Luiggi Agreda, Ney José

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.

Environmental Resource Management in Borderlands: Evolution from Competing Interests to Common Aversions

Directory of Open Access Journals (Sweden)

Patrick Henry Buckley

2015-07-01

Full Text Available Great enthusiasm is attached to the emergence of cross-border regions (CBRs as a new institutional arrangement for dealing with local cross-border environmental resource management and other issues that remain too distant from national capitals and/or too expensive to be addressed in the traditional topocratic manner requiring instead local adhocratic methods. This study briefly discusses the perceived value of CBRs and necessary and sufficient conditions for the successful and sustainable development of such places. Then, assuming that necessary conditions can be met, the study investigates an intriguing hypothesis concerning the catalyzing of sustainable consensus for cross-border resource management based on a game theoretical approach that employs the use of dilemma of common aversion rather than the more traditional dilemma of competing common interests. Using this lens to investigate a series of events on the Pacific northwestern Canadian-American border in a part of the Fraser Lowland, we look for evidence of the emergence of an active and sustainable CBR to address local trans-border resource management issues. Although our micro-level scale fails to conclusively demonstrate such evidence, it does demonstrate the value of using this approach and suggests a number of avenues for further research.

Techno-economic assessment of anaerobic digestion systems for agri-food wastes

Energy Technology Data Exchange (ETDEWEB)

Lau, A.; Baldwin, S.; Wang, M. [British Colombia Univ., Vancouver, BC (Canada)

2010-07-01

Activities in British Columbia's Fraser Valley generate an estimated 3 million tones of agriculture and food wastes annually, of which 85 per cent are readily available for anaerobic digestion. 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.

The Roka Listeria Detection Assay was compared to the reference culture methods for nine select foods and three select surfaces. The Roka method used Half-Fraser Broth for enrichment at 35 +/- 2 degrees C for 24-28 h. Comparison of Roka's method to reference methods requires an unpaired approach. Each method had a total of 545 samples inoculated with a Listeria strain. Each food and surface was inoculated with a different strain of Listeria at two different levels per method. For the dairy products (Brie cheese, whole milk, and ice cream), our method was compared to AOAC Official Method(SM) 993.12. For the ready-to-eat meats (deli chicken, cured ham, chicken salad, and hot dogs) and environmental surfaces (sealed concrete, stainless steel, and plastic), these samples were compared to the U.S. Department of Agriculture/Food Safety and Inspection Service-Microbiology Laboratory Guidebook (USDA/FSIS-MLG) method MLG 8.07. Cold-smoked salmon and romaine lettuce were compared to the U.S. Food and Drug Administration/Bacteriological Analytical Manual, Chapter 10 (FDA/BAM) method. Roka's method had 358 positives out of 545 total inoculated samples compared to 332 positive for the reference methods. Overall the probability of detection analysis of the results showed better or equivalent performance compared to the reference methods.

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)

In the final phase of their spawning migration, Pacific salmon use chemical cues to identify their home river, but how they navigate from the open ocean to the correct coastal area has remained enigmatic. To test the hypothesis that salmon imprint on the magnetic field that exists where they first enter the sea and later seek the same field upon return, we analyzed a 56-year fisheries data set on Fraser River sockeye salmon, which must detour around Vancouver Island to approach the river through either a northern or southern passageway. We found that the proportion of salmon using each route was predicted by geomagnetic field drift: the more the field at a passage entrance diverged from the field at the river mouth, the fewer fish used the passage. We also found that more fish used the northern passage in years with warmer sea surface temperature (presumably because fish were constrained to more northern latitudes). Field drift accounted for 16% of the variation in migratory route used, temperature 22%, and the interaction between these variables 28%. These results provide the first empirical evidence of geomagnetic imprinting in any species and imply that forecasting salmon movements is possible using geomagnetic models.

Krishnan, Sadagopan

2011-05-01

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.

Little has been published on gratification disorder ("infantile masturbation") in early childhood. To expand on the profile of patients diagnosed with this condition. Retrospective case note review; Fraser of Allander Neurosciences Unit paediatric neurology outpatient department 1972-2002. Thirty one patients were diagnosed (11 males and 20 females). Twenty one were referred for evaluation of possible epileptic seizures or epilepsy. The median age at first symptoms was 10.5 months (range 3 months to 5 years 5 months). The median age at diagnosis was 24.5 months (range 5 months to 8 years). The median frequency of events was seven times per week, and the median length 2.5 minutes. Events occurred in any situation in 10 children, and in a car seat in 11. Types of behaviour manifested were dystonic posturing in 19, grunting in 10, rocking in 9, eidetic imagery in 7, and sweating in 6. Two children had been previously diagnosed as having definite epilepsy. In nine cases home video was invaluable in allowing confident diagnosis. Gratification disorder, otherwise called infantile masturbation, is an important consideration in the differential diagnosis of epilepsy and other paroxysmal events in early childhood. Home video recording of events often prevents unnecessary investigations and treatments.

Curation Pedagogy for Media Studies: (Further Towards the Inexpert

Directory of Open Access Journals (Sweden)

Ben Andrews

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.

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

Quantitative methods for analysing cumulative effects on fish migration success: a review.

Science.gov (United States)

Johnson, J E; Patterson, D A; Martins, E G; Cooke, S J; Hinch, S G

2012-07-01

It is often recognized, but seldom addressed, that a quantitative assessment of the cumulative effects, both additive and non-additive, of multiple stressors on fish survival would provide a more realistic representation of the factors that influence fish migration. This review presents a compilation of analytical methods applied to a well-studied fish migration, a more general review of quantitative multivariable methods, and a synthesis on how to apply new analytical techniques in fish migration studies. A compilation of adult migration papers from Fraser River sockeye salmon Oncorhynchus nerka revealed a limited number of multivariable methods being applied and the sub-optimal reliance on univariable methods for multivariable problems. The literature review of fisheries science, general biology and medicine identified a large number of alternative methods for dealing with cumulative effects, with a limited number of techniques being used in fish migration studies. An evaluation of the different methods revealed that certain classes of multivariable analyses will probably prove useful in future assessments of cumulative effects on fish migration. This overview and evaluation of quantitative methods gathered from the disparate fields should serve as a primer for anyone seeking to quantify cumulative effects on fish migration survival. © 2012 The Authors.

Stottlemyer, R.

1997-01-01

Weekly precipitation and stream water samples were collected from small watersheds in Denali National Park, Alaska, the Fraser Experimental Forest, Colorado, Isle Royale National Park, Michigan, and the Calumet watershed on the south shore of Lake Superior, Michigan. The objective was to determine if stream water chemistry at the mouth and upstream stations reflected precipitation chemistry across a range of atmospheric inputs of H+, NH4+, NO3-, and SO42-. Volume-weighted precipitation H+, NH4+, NO3-, and SO42- concentrations varied 4 to 8 fold with concentrations highest at Calumet and lowest in Denali. Stream water chemistry varied among sites, but did not reflect precipitation chemistry. The Denali watershed, Rock Creek, had the lowest precipitation NO3- and SO42- concentrations, but the highest stream water NO3and SO42- concentrations. Among sites, the ratio of mean monthly upstream NO3- concentration to precipitation NO3- concentration declined (p 90 percent inputs) across inputs ranging from 0.12 to > 6 kg N ha-1 y-1. Factors possibly accounting for the weak or non-existent signal between stream water and precipitation ion concentrations include rapid modification of meltwater and precipitation chemistry by soil processes, and the presence of unfrozen soils which permits winter mineralization and nitrification to occur.

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.

Foley, D.

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

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.

Animals navigate using a variety of sensory cues, but how each is weighted during different phases of movement (e.g. dispersal, foraging, homing) is controversial. Here, we examine the geomagnetic and olfactory imprinting hypotheses of natal homing with datasets that recorded variation in the migratory routes of sockeye (Oncorhynchus nerka) and pink (Oncorhynchus gorbuscha) salmon returning from the Pacific Ocean to the Fraser River, British Columbia. Drift of the magnetic field (i.e. geomagnetic imprinting) uniquely accounted for 23.2% and 44.0% of the variation in migration routes for sockeye and pink salmon, respectively. Ocean circulation (i.e. olfactory imprinting) predicted 6.1% and 0.1% of the variation in sockeye and pink migration routes, respectively. Sea surface temperature (a variable influencing salmon distribution but not navigation, directly) accounted for 13.0% of the variation in sockeye migration but was unrelated to pink migration. These findings suggest that geomagnetic navigation plays an important role in long-distance homing in salmon and that consideration of navigation mechanisms can aid in the management of migratory fishes by better predicting movement patterns. Finally, given the diversity of animals that use the Earth's magnetic field for navigation, geomagnetic drift may provide a unifying explanation for spatio-temporal variation in the movement patterns of many species.

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

Science.gov (United States)

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.

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

Science.gov (United States)

Cuthill, Fiona

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.

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.

2016-05-03

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.

Reflexiones sobre un malentendido: producción de necesidades infantiles en políticas de protección

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.

This paper describes the total system, extracted from the achievement report for fiscal 1985 on developing an automatic sewing system. In the study of automating the production system by apparel types, basic and multiple type developments were studied on five representative types of apparels by fiscal 1984. As a result, fiscal 1985 has made it possible to narrow the trial wear down to one type which incorporates characteristics of the five apparel types. It was made possible to focus the study on this type to perform the automation study on the sewing system. Automation procedure was made clear step by step on the series of works including collar fitting, sleeve fitting, side matching, and hem processing as the three-dimensional sewing system being the core technology in the automatic sewing system. Studies from the hardware aspect were executed in the process formation utilizing the new technologies. In the automation study from the production system point of view, the FMS and FA technologies were utilized, and device control was advanced by using NC as the base. In order to complete the study, networking of information and software are important. A simulation program was prepared for the optimized sewing process mixed flexible flow, which incorporates multi-functional stations. (NEDO)

New views on changing Arctic vegetation

means of tracking retrospective changes in Arctic and boreal vegetation. These images are attractive because they are consistent over time, are good at mapping vegetation, are available for areas difficult to reach on the ground, and are of broad geographic extent. In a now-classic study, Myneni et al (1998) used historical reanalysis of AVHRR image data to document changes in vegetation phenology at continental scales in the northern hemisphere, finding patterns of change consistent with impacts of increased growing season in boreal and near-polar regions. The year 2000 launch of the MODIS sensors has allowed even more robust assessment of vegetation change in the Arctic (de Beurs and Henebry 2010) and at global scales (Zhao and Running 2010). Despite opening a window into vegetation change in the Arctic, these studies provide a relatively coarsely filtered view of change. To track trends occurring before the year 2000, researchers are constrained to the large pixel sizes of the AVHRR instrument (nominally 1 km, but typically 4-8 km for derived datasets). Even the finer grain of MODIS (250 m to 1 km resolution) obscures many important natural and anthropogenically derived spatial patterns. The effects of climate change may exacerbate contrasts in competitive status of different vegetative groups (Klady et al 2011, Pieper et al 2011, Seastedt et al 2004). Resolving mechanisms of response requires empirical observation at the scale of individual vegetative communities. Thus, the new work of Fraser et al (2011) represents a critical milestone in climate change related monitoring of Arctic vegetation. Their work is important in three ways. First, the authors provide the first spatially explicit, continuous record of long-term trends in Arctic vegetation condition at a pixel resolution of 30 m. Based on Landsat Thematic Mapper (TM) data reaching back to the mid 1980s, the work required the overcoming of several key methodological challenges to build a dataset from which

An experimental plant systematization study carried out at Tsukuba under the above-named large-scale technological development project is described in the report. All the equipment are carried in, installed, and adjusted; a connection test to the process control computer and a subsystem verification operation are conducted; and then a comprehensive operation/evaluation is conducted, this in cooperation with the apparel hardware manufacturer. As the result, it is confirmed that the subsystem and all the equipment attain the intended levels in every respect of evaluation. Goals are all achieved involving the technologies of high-performance pattern formation, pretreatment for stabilization, multifunctional sewing, measurements for the conveyer system capable of automatic positioning and for the conveyer systems between stations, production control, etc. It is deemed that the research and development effort reported here promises the feasibility of FMS (factory management system), FA (factory automation), and an unmanned plant, which have long been awaited in the apparel business.

A report is compiled about the above-named system being developed under the large-scale industrial technology development project. In the research and development of 'high-performance pattern formation technology,' 'stabilization pretreatment technology,' 'multifunctional sewing technology,' and 'production control technology,' the specifications for each of the component units and the impression they will give have become clear. Though within the limits of the results of operation verification tests conducted for the respective units, it is deemed that each one of them now satisfies the target value for the most part. Researches are conducted by apparel manufactures on the assumption of systematization of the Tsukuba experimental plant, their researches covering the total processing time, amount of production, part shape deformation to occur during the movement of parts, and incorrect workpiece positioning. When the results of the researches are studied, however, it is found that processing time to be consumed at each unit has to be shortened, that deformation of workpieces during processing or movement has to be lessened to the maximum extent, and that the variation in workpiece positioning has to be reduced as much as possible.

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.

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.

Application of wavelet transform for PDZ domain classification.

Full Text Available PDZ domains have been identified as part of an array of signaling proteins that are often unrelated, except for the well-conserved structural PDZ domain they contain. These domains have been linked to many disease processes including common Avian influenza, as well as very rare conditions such as Fraser and Usher syndromes. Historically, based on the interactions and the nature of bonds they form, PDZ domains have most often been classified into one of three classes (class I, class II and others - class III, that is directly dependent on their binding partner. In this study, we report on three unique feature extraction approaches based on the bigram and trigram occurrence and existence rearrangements within the domain's primary amino acid sequences in assisting PDZ domain classification. Wavelet packet transform (WPT and Shannon entropy denoted by wavelet entropy (WE feature extraction methods were proposed. Using 115 unique human and mouse PDZ domains, the existence rearrangement approach yielded a high recognition rate (78.34%, which outperformed our occurrence rearrangements based method. The recognition rate was (81.41% with validation technique. The method reported for PDZ domain classification from primary sequences proved to be an encouraging approach for obtaining consistent classification results. We anticipate that by increasing the database size, we can further improve feature extraction and correct classification.

Geomagnetic imprinting predicts spatio-temporal variation in homing migration of pink and sockeye salmon.

Animals navigate using a variety of sensory cues, but how each is weighted during different phases of movement (e.g. dispersal, foraging, homing) is controversial. Here, we examine the geomagnetic and olfactory imprinting hypotheses of natal homing with datasets that recorded variation in the migratory routes of sockeye (Oncorhynchus nerka) and pink (Oncorhynchus gorbuscha) salmon returning from the Pacific Ocean to the Fraser River, British Columbia. Drift of the magnetic field (i.e. geomagnetic imprinting) uniquely accounted for 23.2% and 44.0% of the variation in migration routes for sockeye and pink salmon, respectively. Ocean circulation (i.e. olfactory imprinting) predicted 6.1% and 0.1% of the variation in sockeye and pink migration routes, respectively. Sea surface temperature (a variable influencing salmon distribution but not navigation, directly) accounted for 13.0% of the variation in sockeye migration but was unrelated to pink migration. These findings suggest that geomagnetic navigation plays an important role in long-distance homing in salmon and that consideration of navigation mechanisms can aid in the management of migratory fishes by better predicting movement patterns. Finally, given the diversity of animals that use the Earth's magnetic field for navigation, geomagnetic drift may provide a unifying explanation for spatio-temporal variation in the movement patterns of many species. © 2014 The Author(s) Published by the Royal Society.

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.

International protocol on volatile organic compounds

International Nuclear Information System (INIS)

Gauthier, J.-P.

1992-01-01

In August 1991, negotiations between Canada, the USA, and 33 European countries led to an international protocol on reducing the emissions of volatile organic compounds (VOC), which are responsible for serious ozone pollution problems. This was the third transborder pollution agreement developed under the auspices of the United Nations Economic Commission for Europe. Certain aspects of negotiations related to an earlier protocol developed for SO 2 and nitrogen oxide emissions had reappeared during the VOC negotiations, and these aspects are discussed. The VOC protocol proposes three approaches to satisfy basic obligations: reducing VOC emissions of a country by 30%, reducing VOC emissions by 30% in certain regions, and ensuring a freeze in VOC emissions in a country starting on a specified date. The protocol also introduces a new concept, that of zones of tropospheric ozone management. In Canada, plans for management of nitrogen oxides and VOC have been adapted to the ozone problem, and the management plan has been developed by a consultation process involving all sectors of society including industry, environmental groups, and governments. In Canada, it will be sufficient to reduce total VOC emissions by 16% during a first phase and to increase these reductions slightly in the second phase. Special ozone management zones in the Quebec City/Windsor corridor and the Fraser River valley have been established

This paper describes the cloth handling technology, extracted from the achievement report for fiscal 1985 on developing an automatic sewing system. Development, experiment and evaluation were made on prototype cloth holding modules of vertical type and horizontal type. For a cloth operation type module, a principle model was developed. The cloth holding technology has a number of problems to be solved in the future, including systematization and application conditions of the holding devices. In improving the function of sewing process positioning, problems in devices were extracted, and functions to be added were put in order. Basics of the concept for the pressing process positioning was made clear, examples of the process layout drawings were prepared, and weights by processes were measured and put in order to discuss the holding force. The handler was given redundancy, and constructed with seven shafts to make it capable of avoiding obstacles, thereby having reduced the weight and size by 15%. The calculation operating time in a servo control module was shortened. The basic design was completed on the specifications for a coordinated operation control system. Discussions were given on functions and specifications of different constituting modules as a study on formation of the system to transport flexible cloths. (NEDO)

Capture-zone design in an aquifer influenced by cyclic fluctuations in hydraulic gradients

Science.gov (United States)

Zawadzki, Willy; Chorley, Don; Patrick, Guy

2002-10-01

Design of a groundwater pumping and treatment system for a wood-treatment facility adjacent to the tidally influenced Fraser River estuary required the development of methodologies to account for cyclic variations in hydraulic gradients. Design of such systems must consider the effects of these cyclic fluctuations on the capture of dissolved-phase contaminants. When the period of the cyclic fluctuation is much less than the travel time of the dissolved contaminant from the source to the discharge point, the hydraulic-gradient variations resulting from these cycles can be ignored. Capture zones are then designed based on the average hydraulic gradient determined using filter techniques on continuous groundwater-level measurements. When the period of cyclic fluctuation in hydraulic gradient is near to or greater than the contaminant travel time, the resulting hydraulic-gradient variations cannot be ignored. In these instances, procedures are developed to account for these fluctuations in the capture-zone design. These include proper characterization of the groundwater regime, assessment of the average travel time and period of the cyclic fluctuations, and numerical techniques which allow accounting for the cyclic fluctuations in the design of the capture zone. Résumé. L'étude d'un système de pompage et de traitement de l'eau souterraine d'une usine de traitement du bois proche de l'estuaire de la rivière Fraser, influencé par les marées, a nécessité la mise au point de méthodologies pour prendre en compte les variations cycliques de gradients hydrauliques.

The paper summarized the R and D of a cloth handling technology which is an element technology of an automatic sewing system by the Automatic Sewing System Technology Research Association. The cloth handling technology is divided into the following three: (1) cloth grasp technology; (2) high-functional positioning technology; (3) element technology of soft cloth conveying technology. In (1), development of the following was conducted: vertical grasp-type module, horizontal grasp-type module, cloth handling-type module, and auxiliary device. Prototypes of each were trially manufactured for experiment on the function confirmation. In (2), the following were conducted: development of experimental models of module handler and module controller for commercialization; study of visual/tactile sense composite multiple-arm cooperative movement control. In (3), in the studies having been made so far, specifications for an experimental model for joint sawing and specifications for the conveying system were studied, and experimental models of stock module and junction module were manufactured/tested/evaluated to study confirmation of function/performance. In this fiscal year, in the light of these results obtained, prototypes of each element device were developed. At the same time, the connection of these element devices made up an experimental model for joint sawing, and effectiveness of the element technology was confirmed in the system. (NEDO)

A report is compiled about the above-named system being developed under the large-scale industrial technology development project. In the research and development of automatic sewing technologies, the cloth manipulation type module is being improved and the entirety of the automatic sewing system and a cloth opening system are under development, and now they are believed to be usable in the experimental plant. In the research and development of opening seam press technologies, overall design improvement and manufacture are accomplished for the opening seam press system based on the result of systematization researches, and the system is now fit for conveying and positioning the cloth on its way from the previous stage to the next stage. In the research on the ventral coordination control type assemble sewing technology, every unit involved is improved, designed, and manufactured, and software programs for their control are also developed and improved. It is now enhanced in reliability, operationality, workability, and seam quality, and is expected to be usable in the experimental plant. As for the research on retrofitting, it is found in a reliability test that its reliability is still short of the target value of 99.9%. (NEDO)

Using Silviculture to Influence Carbon Sequestration in Southern Appalachian Spruce-Fir Forests

Full Text Available Enhancement of forest growth through silvicultural modification of stand density is one strategy for increasing carbon (C sequestration. Using the Fire and Fuels Extension of the Forest Vegetation Simulator, the effects of even-aged, uneven-aged and no-action management scenarios on C sequestration in a southern Appalachian red spruce-Fraser fir forest were modeled. We explicitly considered C stored in standing forest stocks and the fate of forest products derived from harvesting. Over a 100-year simulation period the even-aged scenario (250 Mg C ha⁻¹ outperformed the no-action scenario (241 Mg C ha⁻¹ in total carbon (TC sequestered. The uneven-aged scenario approached 220 Mg C ha⁻¹, but did not outperform the no-action scenario within the simulation period. While the average annual change in C (AAC of the no-action scenario approached zero, or carbon neutral, during the simulation, both the even-aged and uneven-aged scenarios surpassed the no-action by year 30 and maintained positive AAC throughout the 100-year simulation. This study demonstrates that silvicultural treatment of forest stands can increase potential C storage, but that careful consideration of: (1 accounting method (i.e., TC versus AAC; (2 fate of harvested products and; (3 length of the planning horizon (e.g., 100 years will strongly influence the evaluation of C sequestration.

Modelling study of sea breezes in a complex coastal environment

Science.gov (United States)

Cai, X.-M.; Steyn, D. G.

This study investigates a mesoscale modelling of sea breezes blowing from a narrow strait into the lower Fraser valley (LFV), British Columbia, Canada, during the period of 17-20 July, 1985. Without a nudging scheme in the inner grid, the CSU-RAMS model produces satisfactory wind and temperature fields during the daytime. In comparison with observation, the agreement indices for surface wind and temperature during daytime reach about 0.6 and 0.95, respectively, while the agreement indices drop to 0.4 at night. In the vertical, profiles of modelled wind and temperature generally agree with tethersonde data collected on 17 and 19 July. The study demonstrates that in late afternoon, the model does not capture the advection of an elevated warm layer which originated from land surfaces outside of the inner grid. Mixed layer depth (MLD) is calculated from model output of turbulent kinetic energy field. Comparison of MLD results with observation shows that the method generates a reliable MLD during the daytime, and that accurate estimates of MLD near the coast require the correct simulation of wind conditions over the sea. The study has shown that for a complex coast environment like the LFV, a reliable modelling study depends not only on local surface fluxes but also on elevated layers transported from remote land surfaces. This dependence is especially important when local forcings are weak, for example, during late afternoon and at night.

Full Text Available This article summarizes the findings of a study on e-resource knowledge bases and OpenURL-based link resolvers sponsored by the National Library of Sweden. The project involved soliciting detailed information from each of the providers of the major products in this genre, reviewing product information available on the web and in published articles, and conducting a survey addressed to libraries using these products. The report identified and presented comparative information on a top tier of products that includes KnowledgeWorks and 360 Link from Serials Solutions; SFX Global KnowledgeBase and the SFX link resolver from Ex Libris; LinkSource and the EBSCO Integrated Knowledge Base from EBSCO and the WorldCat knowledge base from OCLC. A second tier included TOUResolver from TDNet, Gold Rush from the Colorado Alliance of Research Libraries and GODOT from Simon Fraser University. Innovative Interfaces, Inc offers the WebBridge link resolver but does not produce a knowledge base. The library survey revealed relatively narrow differences in the statistical results. Serial Solutions emerged as more favorable in most categories except for end-user functionality where Ex Libris received higher ratings. The Global Open Knowledgebase project (GOKb is noteworthy as a nascent community-based effort to produce a knowledge base. Key trends noted include less emphasis on knowledge bases and link resolvers as stand-alone products as they become integral components of comprehensive discovery and automation products.

Transportation and air quality

International Nuclear Information System (INIS)

Roseland, M.

1992-01-01

In the greater Vancouver regional district (GVRD), some 80% of the annual production of 600,000 tonnes of air pollutants come from motor vehicles. Three critical air quality issues in the GVRD are discussed: local air pollution, ozone layer depletion, and greenhouse gas emissions, all of which are fundamentally linked to transportation. Overall air quality in the GVRD has been judged acceptable by current federal standards, but ground-level ozone has exceeded maximum tolerable levels at some locations and concentrations of suspended particulates are above maximum acceptable levels. Serious deterioration in air quality has been predicted unless a concerted effort is made to manage air quality on an airshed-wide basis. The GVRD is developing Canada's first Air Management Plan with the goal of halving atmospheric emissions by 2000. GVRD transportation priorities stress public transit, walking, cycling, car pooling, and reducing of travel demand; however, the viability of such strategies depends on decisions made outside the transportation sector. Restricted authority and jurisdiction also hinder GVRD goals; the regional level of government has no authority over highways or transit and only has authority for pollution control in some parts of the Fraser Valley. Airshed quality management, using the Los Angeles example, is seen as a possible direction for future GVRD policymaking in the transportation sector. A single regional planning agency with responsibility for transportation, land use, and air quality management appears as the best option for an integrated approach to solve multiple problems. 19 refs

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

Size structure of marine soft-bottom macrobenthic communities across natural habitat gradients: implications for productivity and ecosystem function.

Full Text Available Size distributions of biotic assemblages are important modifiers of productivity and function in marine sediments. We investigated the distribution of proportional organic biomass among logarithmic size classes (2(-6J to 2(16J in the soft-bottom macrofaunal communities of the Strait of Georgia, Salish Sea on the west coast of Canada. The study examines how size structure is influenced by 3 fundamental habitat descriptors: depth, sediment percent fines, and organic flux (modified by quality. These habitat variables are uncorrelated in this hydrographically diverse area, thus we examine their effects in combination and separately. Cluster analyses and cumulative biomass size spectra reveal clear and significant responses to each separate habitat variable. When combined, habitat factors result in three distinct assemblages: (1 communities with a high proportion of biomass in small organisms, typical of shallow areas (3 g C/m(2/yr/δ(15N from the Fraser River; and (3 communities with biomass dominated by moderately large organisms, but lacking the smallest and largest size classes, typical of deep, fine sediments experiencing low modified organic flux (<3.0 gC/m(2/yr/δ(15N. The remaining assemblages had intermediate habitat types and size structures. Sediment percent fines and flux appear to elicit threshold responses in size structure, whereas depth has the most linear influence on community size structure. The ecological implications of size structure in the Strait of Georgia relative to environmental conditions, secondary production and sediment bioturbation are discussed.

Full Text Available This paper is part of the doctoral thesis entitled “Critique of translation for film dubbing and subtitling from the perspective of discourse analysis. A study applied to "The Green Mile”, written by Ph.D. student Gabriela Saturnina Alanís Uresti, directed by Ph.D. Lidia Rodríguez. It is a qualitative and descriptive study where we contrasted The Green Mile - a 1999 Hollywood film, original in American English - with its translated versions: dubbed and subtitled into Spanish of Mexico. We start from the presupposition that in film translation, some references such as the ones related to sexual behaviors and offensive language are attenuated in order to be strategically polite. Specifically, we analyzed two mechanisms of attenuation: lexical selection whereby a euphemism is used, and discursive modalization. These mechanisms constitute strategies of linguistic, pragmatic and semiotic nature as they appear in original (OV, dubbed (DV and subtitled (SV versions; both in acoustic and visual channels. Therefore, we examine these occurrences on verbal, para-verbal, and non-verbal codes. The theoretical basis includes studies of attenuation, politeness, euphemisms, and linguistic taboos.

"geoNatHaz" is a Transatlantic Exchange Partnership project (TEP 2009-2012) within the framework of the EU-Canada programme for co-operation in higher education, training, and youth. The project is structured to improve knowledge and skills required to assess and manage natural hazards in mountain regions. It provides student exchanges between European and Canadian universities in order to enhance international competence in natural hazard research. The university consortium is led by Simon Fraser University (Canada) and Università degli studi di Torino (Italy). Partner universities include the University of British Columbia, Queen's University, Università di Bologna, Université de Savoie, and the University of Athens. Université de Lausanne (Switzerland) supports the geoNatHaz advisory board through its bilateral agreements with Canadian partner universities. The geoNatHaz project promotes cross-cultural understanding and internationalization of university natural hazard curricula through common lectures, laboratory exercises, and field activities. Forty graduate students from the seven Canadian and European partner universities will benefit from the project between 2009 and 2012. Some students enrolled in graduate-level earth science and geologic engineering programs spend up to five months at the partner universities, taking courses and participating in research teams under the direction of project scientists. Other students engage in short-term (four-week) exchanges involving training in classic natural hazard case-studies in mountain regions of Canada and Europe. Joint courses are delivered in English, but complementary cultural activities are offered in the languages of the host countries. Supporting organizations offer internships and technical and scientific support. Students benefit from work-study programs with industry partners.

This paper describes the production systems by apparel types from among the achievement report for fiscal 1988 on developing an automatic sewing system. Studies were continued on model wears as the experimental objects for the apparel side studies, and the processing manuals were expanded and improved. In order to expand application of the automatic sewing system technology, design studies were moved forward on an experimental plant for five kinds of apparels, namely tops, bottoms, dresses, sports wears and night wears to prepare for the comprehensive operation of the plant. The study items included such items as layout, handling, communications, utilities, and buildings. Factory design drawings and layout drawings were drawn on trial wear experimenting plants by apparel types. In the FA/FMS study, it was decided to study the factory design taking ladies' blazer coats as the object, whereas shortening the production time was discussed, and the device and software specifications were written up. Changing and switching of cloths and sizes for the five apparel types will be performed during the plant operation studies. Cooperation is tightened between subcommittees for adjusting the experimental plant schedule and technical problems. (NEDO)

Privatisation of the UK's nuclear power industry: nuclear's triple challenge

International Nuclear Information System (INIS)

Fraser, W.R.I.

1997-01-01

At the British Nuclear Congress in December 1996, Lord Fraser of Caryllie, then UK energy minister, set out the three key issues the nuclear industry must tackle for a successful future: (1) increased competition from other energy sources, (2) a growing world market for its skills and (3) a continuing tough regulatory regime. Nuclear power, with electricity generated in the UK rising to 25%, has responded well to competition from other energy sources, and also to the further competition generated by privatisation which has already generated benefits for the public. As other countries with nuclear programmes diversify and upgrade their technology this will create new export opportunities for Britain over and above those already in existence, notably by BNFL in Japan. Other areas that Britain has to offer relate to safety improvements, notably in eastern Europe, and decommissioning, in which Magnox Electric is one of the few operators in the world with experience in decommissioning a full scale commercial reactor. The regulatory framework for the nuclear industry will continue to be as rigorous as ever, but, however the industry is structured, it should be noted that commercial success and continued safe operations are inextricably linked. The industry must operate within the framework of the development of international treaties and agreements in the nuclear field. The Government will continue to take a close interest in the safety, security and prosperity of the nuclear industry, and help Britain as a whole to be a successful and influential player in the international nuclear community.

The introduction of genetically modified (GM) crops into the market has raised a general alertness relating to the control and safety of foods. The applicability of protein separation hyphenated to mass spectrometry to identify the bacterial enolpyruvylshikimate-3-phosphate synthase (CP4 EPSPS) protein expressed in GM crops has been previously reported [M.F. Ocana, P.D. Fraser, R.K.P. Patel, J.M. Halket, P.M. Bramley, Rapid Commun. Mass Spectrom. 21 (2007) 319.]. Herein, we investigate the suitability of two strategies that employ heavy stable isotopes, i.e. AQUA and iTRAQ, to quantify different levels of CP4 EPSPS in up to four GM preparations. Both quantification strategies showed potential to determine whether the presence of GM material is above the limits established by the European Union. The AQUA quantification procedure involved protein solubilisation/fractionation and subsequent separation using SDS-PAGE. A segment of the gel in which the protein of interest was located was excised, the stable isotope labeled peptide added at a known concentration and proteolytic digestion initiated. Following recovery of the peptides, on-line separation and detection using LC-MS was carried out. A similar approach was used for the iTRAQ workflow with the exception that proteins were digested in solution and generated tryptic peptides were chemically tagged. Both procedures demonstrated the potential for quantitative detection at 0.5% (w/w) GM soya which is a level below the current European Union's threshold for food-labelling. In this context, a comparison between the two procedures is provided within the present study.

Skaha Lake crossing, innovations in pipeline installation

This paper describes the construction of a 10.8 km long NPS16 (406 mm, 16 inch diameter) pipeline, across Skaha Lake, in the south Okanagan valley, British Columbia, Canada. The water crossing is part of the 32 km South Okanagan Natural Gas Pipeline Project (SONG) operated by BC Gas. The pipeline is located in a region dependent on year-round tourism. Therefore, the design and construction was influenced by sensitive environmental and land use concerns. From earlier studies, BC Gas identified surface tow or lay as preferred installation methods. The contractor, Fraser River Pile and Dredge departed from a conventional laybarge methodology after evaluating environmental data and assessing locally available equipment. The contractor proposed a surface tow with multiple surface tie-ins. This approach modification to the ''Surface Tow and Buoy Release Method'' (STBRM) used previously with success on relatively short underwater pipelines. A total of 10 pipe strings, up to 1 km long, were towed into position on the lake and tied-in using a floating platform. The joined pipeline was lowered to the lakebed by divers releasing buoys while tension was maintained from a winch barge at the free end of the pipeline. From analysis and field verified measurement the installation stresses were well below the allowable limits during all phases of construction. The entire construction, including mobilization and demobilization, lasted less than three months, and actual pipelaying less than three weeks. Installation was completed within budget and on schedule, without any environmental or safety related incidents. The SONG pipeline became operational in December 1994

Single Cell Electroporation Method for Mammalian CNS Neurons in Organotypic Slice Cultures

Uesaka, Naofumi; Hayano, Yasufumi; Yamada, Akito; Yamamoto, Nobuhiko

Axon tracing is an essential technique to study the projection pattern of neurons in the CNS. Horse radish peroxidase and lectins have contributed to revealing many neural connection patterns in the CNS (Itaya and van Hoesen, 1982; Fabian and Coulter, 1985; Yoshihara, 2002). Moreover, a tracing method with fluorescent dye has enabled the observation of growing axons in living conditions, and demon strated a lot of developmental aspects in axon growth and guidance (Harris et al., 1987; O'Rourke and Fraser, 1990; Kaethner and Stuermer, 1992; Halloran and Kalil, 1994; Yamamoto et al., 1997). More recently, genetically encoded fluores cent proteins can be used as a powerful tool to observe various biological events. Several gene transfer techniques such as microinjection, biolistic gene gun, viral infection, lipofection and transgenic technology have been developed (Feng et al., 2000; Ehrengruber et al., 2001; O'Brien et al., 2001; Ma et al., 2002; Sahly et al., 2003). In particular, the electroporation technique was proved as a valuable tool, since it can be applied to a wide range of tissues and cell types with little toxicity and can be performed with relative technical easiness. Most methods, including a stand ard electroporation technique, are suitable for gene transfer to a large number of cells. However, this is not ideal for axonal tracing, because observation of individ ual axons is occasionally required. To overcome this problem, we have developed an electroporation method using glass micropipettes containing plasmid solutions and small current injection. Here we introduce the method in detail and exemplified results with some example applications and discuss its usefulness.

POSTPARTUM BONDING DIFFICULTIES AND ADULT ATTACHMENT STYLES: THE MEDIATING ROLE OF POSTPARTUM DEPRESSION AND CHILDBIRTH-RELATED PTSD.

Despite decades of research demonstrating the role of adult attachment styles and early mother-infant bonding in parenting behaviors and maternal mental health, these constructs have seldom been studied together. The present study aimed to investigate the relationship between attachment styles and specific bonding difficulties of mothers. In addition, as postpartum depression and childbirth-related posttraumatic stress symptoms have been associated with both constructs, we explored their possible mediation effect. One hundred fourteen mothers, 4 to 12 weeks' postpartum, completed a demographic questionnaire, the Adult Attachment Style Questionnaire (M. Mikulincer, V. Florian, & A. Tolmacz, 1990), the Postpartum Bonding Questionnaire (L.F. Brockington, C. Fraser, & D. Wilson, 2006), the Modified Perinatal Posttraumatic Stress Disorder Questionnaire (J.L. Callahan, S.E. Borja, & M.T. Hynan, 2006), and the Edinburgh Postnatal Depression Scale (J.L. Cox, G. Chapman, D. Murray, & P. Jones, 1996), using an online survey system. As predicted, insecure attachment styles were associated with bonding difficulties wherein anxious/ambivalent attachment was associated with greater infant-focused anxiety, mediated by postpartum depression but not childbirth-related PTSD symptoms. In contrast, greater avoidant attachment style was associated with greater rejection and anger, mediated by childbirth-related posttraumatic stress disorder (PTSD), but not depression symptoms. The current study confirmed the association of different attachment styles with bonding as well as the mediating roles of childbirth-related PTSD and postpartum depression symptoms. Future psychological interventions may utilize such evidence to target interventions for bonding disorders in accordance with individual differences. © 2018 Michigan Association for Infant Mental Health.

The objectives of the study were to 1) describe the implementation of the "Testing is Healthy" campaign in four locations in British Columbia (BC) and 2) report process evaluation indicators for the campaign. Young adults ages 20-29 years, the age group with the highest reported rates of chlamydia and gonorrhea in BC. Movie theatres located in Langley, Burnaby, Coquitlam and Surrey, which are communities served by the Fraser Health Authority (FHA) in BC. The FHA launched the campaign in 2014 and 2015 to bring down the prevalence of sexually transmitted infections (STIs) and HIV in the region. The campaign used the Cineplex TimePlay platform to engage moviegoers in answering STI/HIV-related questions, and to connect them to a clinic finder on the BC Centre for Disease Control Sex Smart Resource (SSR) website. TimePlay includes elements of gaming, is technology-based, and has been a successful advertisement platform for consumer products and services. However, this is the first time it has been used for sexual health promotion. The campaign was evaluated for 1) reach, based on theatre attendance and TimePlay participation, and 2) the effectiveness of connecting people to sexual health information using SSR web analytics. In total, the campaign received 548 410 views and 77 149 plays.

Multi-decadal records of monthly sea surface temperature (SST) and sea surface salinity (SSS) collected at a set of lighthouse stations are used to examine climatic variability and trends in the coastal waters of British Columbia. Particular attention is given to relations between the water property anomalies and variability in coastal freshwater discharge and alongshore wind stress. Within the Strait of Georgia, SSS anomalies are closely related to Fraser River discharge anomalies. Along the Pacific coast, anomalies in alongshore wind stress and freshwater runoff have the characteristics of white noise processes. A cross-correlation analysis demonstrates that SST and SSS variability along the open west coast is consistent with the response of a first-order autoregressive process driven by anomalous alongshore wind stress and coastal freshwater discharge, respectively. Thus climatic variability of SST and SSS along the Pacific coast of British Columbia occurs, in part, through the integration of noisy atmospheric forcing and coastal precipitation. Seasonal correlations show that SST is strongly related to wind stress during winter and fall. Conversely, SSS is relatively weakly related to the alongshore wind during spring, suggesting that variability in upwelling makes only a modest contribution to variability of SSS in the nearshore environment. Consistent with previous studies, secular trends indicate long-term warming and freshening of the coastal ocean at most stations. It is shown that long-term SST trends can be obscured by the pronounced climatic variability of these waters, requiring that time series extend for several decades to be reliably detected.

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.

Pipelines and salmon in northern British Columbia : potential impacts

International Nuclear Information System (INIS)

Levy, D.A.

2009-10-01

Four pipeline projects have been proposed for northern British Columbia that could threaten the health of the Fraser, Skeena, and Kitimat watersheds. The pipelines will expose salmon to risks on several fronts. Enbridge's Northern Gateway pipeline project has generated the most concern for a several reasons, including the risks to salmon and freshwater habitat from pipeline failures, notably leaks or ruptures. This paper reviewed the salmon resources in affected watersheds; salmon and BC's economy; salmon diversity and abundance; impacts on fish from pipeline construction, operations and failures; behaviours of different petroleum products in fresh water; hydrocarbon toxicity; history of pipeline failures; sabotage and natural disasters; and Canadian case studies. Salmon are already experiencing stresses from forestry, hydro-electricity, transportation, agriculture, mining, mountain pine beetle, climate change and coalbed methane development. Their cumulative impact will dictate the long-term health and viability of salmon. It was concluded that if all of the proposed pipelines were built, they would extend over 4,000 km, crossing more than 1,000 rivers and streams in some of Canada's most productive salmon habitat. During construction, pipeline stream crossings are vulnerable to increased sedimentation, which can degrade salmon habitat. In the event of a spill, the condensate and oil sands products carried in the pipelines are highly toxic to salmon, with serious and lasting adverse impacts on salmon and their habitat. Any decision to approve such a pipeline should be made in recognition of these risks. 73 refs., 5 tabs., 15 figs., 2 appendices.

THE HUBBLE WIDE FIELD CAMERA 3 TEST OF SURFACES IN THE OUTER SOLAR SYSTEM: SPECTRAL VARIATION ON KUIPER BELT OBJECTS

2015-01-01

Here, we present additional photometry of targets observed as part of the Hubble Wide Field Camera 3 (WFC3) Test of Surfaces in the Outer Solar System. Twelve targets were re-observed with the WFC3 in the optical and NIR wavebands designed to complement those used during the first visit. Additionally, all of the observations originally presented by Fraser and Brown were reanalyzed through the same updated photometry pipeline. A re-analysis of the optical and NIR color distribution reveals a bifurcated optical color distribution and only two identifiable spectral classes, each of which occupies a broad range of colors and has correlated optical and NIR colors, in agreement with our previous findings. We report the detection of significant spectral variations on five targets which cannot be attributed to photometry errors, cosmic rays, point-spread function or sensitivity variations, or other image artifacts capable of explaining the magnitude of the variation. The spectrally variable objects are found to have a broad range of dynamical classes and absolute magnitudes, exhibit a broad range of apparent magnitude variations, and are found in both compositional classes. The spectrally variable objects with sufficiently accurate colors for spectral classification maintain their membership, belonging to the same class at both epochs. 2005 TV189 exhibits a sufficiently broad difference in color at the two epochs that span the full range of colors of the neutral class. This strongly argues that the neutral class is one single class with a broad range of colors, rather than the combination of multiple overlapping classes

Objective: To compare the validity of a new index (Hb X RDW X 100/ (RBC)/sup 2/ X MCHC) with twelve discriminating functions (DFs) to differentiate iron deficiency anemia (IDA) and beta-thalassemia trait (beta-TT). Methodology: A total of 823 patients (317 IDA and 506 beta-TT) aged 15 to 35 year old were enrolled in this study. The diagnostic sensitivity, specificity and other validity parameters were calculated to assess the diagnostic reliability of the novel index [Keikhaei index (KI)] vis-a-vis the other published DFs [Mentzer Index (MI), Green and King Index (G and KI), red cell distribution width index (RDWI), England and Fraser Index (E and FI), Bessman and Feinstein index (B and FI), Telmissani et al index (TI), Srivastava and Bevington index (S and BI), Shine and Lal index (S and LI), Ricerca et al index (RI), Ehsani et al index (EI), Sirdah et al index (SI), and Red Blood Cell Count(RBC)] were calculated in all patients. Results: All thirteen DFs did not have the sensitivity and specificity of 100%. The KI, RDWI, Gand KI and E and FI showed the most sensitivity and specificity for both IDA and TT; moreover, the lowest reliable indices belonged to B and FI, SandLI and RI. Conclusion: According to Youden's index (YI), DFs in the order of highest to lowest were KI > G and KI > RDWI > E and FI > RBC> M I> EI > TI > SI > S and BI > RI> SandLI >B and FI. (author)

The introduction of genetically modified (GM) crops into the market has raised a general alertness relating to the control and safety of foods. The applicability of protein separation hyphenated to mass spectrometry to identify the bacterial enolpyruvylshikimate-3-phosphate synthase (CP4 EPSPS) protein expressed in GM crops has been previously reported [M.F. Ocana, P.D. Fraser, R.K.P. Patel, J.M. Halket, P.M. Bramley, Rapid Commun. Mass Spectrom. 21 (2007) 319.]. Herein, we investigate the suitability of two strategies that employ heavy stable isotopes, i.e. AQUA and iTRAQ, to quantify different levels of CP4 EPSPS in up to four GM preparations. Both quantification strategies showed potential to determine whether the presence of GM material is above the limits established by the European Union. The AQUA quantification procedure involved protein solubilisation/fractionation and subsequent separation using SDS-PAGE. A segment of the gel in which the protein of interest was located was excised, the stable isotope labeled peptide added at a known concentration and proteolytic digestion initiated. Following recovery of the peptides, on-line separation and detection using LC-MS was carried out. A similar approach was used for the iTRAQ workflow with the exception that proteins were digested in solution and generated tryptic peptides were chemically tagged. Both procedures demonstrated the potential for quantitative detection at 0.5% (w/w) GM soya which is a level below the current European Union's threshold for food-labelling. In this context, a comparison between the two procedures is provided within the present study

Elk River Watershed - Flood Study

Flooding has the potential to cause significant impacts to economic activities as well as to disrupt or displace populations. Changing climate regimes such as extreme precipitation events increase flood vulnerability and put additional stresses on infrastructure. Potential flooding from just under 100 (2009 NPRI Reviewed Facility Data Release, Environment Canada) toxic tailings ponds located in Canada increase risk to human safety and the environment. One such geotechnical failure spilt billions of litres of toxic tailings into the Fraser River watershed, British Columbia, when a tailings pond dam breach occurred in August 2014. Damaged and washed out roadways cut access to essential services as seen by the extensive floods that occurred in Saskatchewan and Manitoba in July 2014, and in Southern Alberta in 2013. Recovery efforts from events such as these can be lengthy, and have substantial social and economic impacts both in loss of revenue and cost of repair. The objective of this study is to investigate existing conditions in the Elk River watershed and model potential future hydrological changes that can increase flood risk hazards. By analyzing existing hydrology, meteorology, land cover, land use, economic, and settlement patterns a baseline is established for existing conditions in the Elk River watershed. Coupling the Generate Earth Systems Science (GENESYS) high-resolution spatial hydrometeorological model with flood hazard analysis methodology, high-resolution flood vulnerability base line maps are created using historical climate conditions. Further work in 2015 will examine possible impacts for a range of climate change and land use change scenarios to define changes to future flood risk and vulnerability.

Full Text Available Este artículo describe los sentidos morales, éticos y políticos que para un grupo de jóvenes universitarios del programa de Licenciatura en lengua castellana, inglés y francés de la Facultad de Ciencias de la Educación de la Universidad de La Salle de Bogotá, Colombia, tienen sus prácticas ciudadanas. Se realizó una investigación cualitativa, siguiendo el enfoque etnográfico, con información sistematizada y analizada resultante de la elaboración de cinco talleres pedagógicos para interpretar y comprender dichos sentidos. Como fundamentación teórica se retomaron planteamientos de Taylor (1994, 1996, 1997, 2004, 2006, Fraser y Honneth (2006 y Honneth (1997, 2007, 2009, sobre reconocimiento y reificación. Algunos resultados e inferencias dan cuenta del vaciamiento de sentido, el tedio y hasta el hastío que sienten los jóvenes cuando no se presentan, desde el marco administrativo e institucional, condiciones justas, de equidad y de justicia redistributiva. Se concluye que para los jóvenes es necesario que el Estado y sus instituciones reconozcan tanto las condiciones de afectación de la dignidad, como los efectos que puede llegar a tener una política pública en las subjetividades ciudadanas. Igualmente, el Estado debe preguntarse por las motivaciones morales e intencionalidades políticas que tendrían los jóvenes para vincularse solidariamente al acuerdo normativo constitucional

Because the organogenesis and physiology of the lens are essentially similar in various mammals, an understanding of the etiology and pathogenesis of the formation of cataract in an animal model will enhance our knowledge of cataractogenesis in man. In this review, we summarize the background, etiology, and pathogenesis of cataracts that occur in rodents. The main advantages of using rodent mutants include the well-researched genetics of the animals and the comparative ease of breeding of large litters. Numerous rodent models of congenital and hereditary cataracts have been studied extensively. In mice, the models include the Cts strain, Fraser mouse, lens opacity gene (Lop) strain, Lop-2 and Lop-3 strains, Philly mouse, Nakano mouse, Nop strain, Deer mouse, Emory mouse, Swiss Webster strain, Balb/c-nct/nct mouse, and SAM-R/3 strain. The rat models include BUdR, ICR, Sprague-Dawley, and Wistar rats, the spontaneously hypertensive rat (SHR), the John Rapp inbred strain of Dahl salt-sensitive rat, as well as WBN/Kob, Royal College of Surgeons (RCS), and Brown-Norway rats. Other proposed models for the study of hereditary cataract include the degu and the guinea pig. Because of the ease of making clinical observations in vivo and the subsequent availability of the intact lens for laboratory analyses at different stages of cataract formation, these animals provide excellent models for clinicopathologic correlations, for monitoring of the natural history of the aging process and of metabolic defects, as well as for investigations on the effect of cataract-modulating agents and drugs, including the prospect of gene therapy.

William (Bill) E. Vidaver (February 2, 1921-August 31, 2017), who did his Ph.D. with Laurence (Larry) R. Blinks at Stanford (1964) and a postdoc with C. Stacy French (1965), taught and did research at Simon Fraser University (SFU) for almost 30 years. Here he published over 80 papers in photosynthesis-related areas co-authored by his graduate students, postdocs, visiting professors and SFU colleagues. He developed a unique high-pressure cuvette for the study of oxygen exchange and studied high-pressure effects in photosynthesis. Ulrich (Uli) Schreiber, as a postdoctoral fellow from Germany, introduced measurements on chlorophyll (Chl) a fluorescence to Bill's lab, leading to the discovery of reversible inhibition of excitation energy transfer between photosynthetic pigments and of a pivotal role of O 2 in the oxidation of the electron transport chain between Photosystem II (PS II) and PS I. Bill's and Uli's work led to a patent of a portable chlorophyll fluorometer, the first available commercially, which was later modified to measure whole plantlets. The latter was used in pioneering measurement of the health of forest and crop plants undergoing in vitro clonal micropropagation. With several other researchers (including Doug Bruce, the late Radovan Popovic, and Sarah Swenson), he localized the quenching site of O 2 and showed a dampening effect on measurements of the four-step process of O 2 production by endogenous oxygen uptake. Bill is remembered as a hard-working but fun-loving person with a keen mind and strong sense of social justice.

From 1994 to 1999 in the Lower Fraser Valley region of southwest Canada, fonofos (Dyfonate G) was recommended for control of introduced wireworm (Agriotes spp.) pests on potato and other root crops. As part of a wildlife-monitoring program, we collected 15 raptors, including 12 bald eagles (Haliaeetus leucocephalus), found dead or debilitated on or near agricultural lands with severely inhibited brain and/or plasma cholinesterase activity and fonofos residues in ingesta. Bird remains, in nine cases waterfowl, were identified in the ingesta samples. Another seven bald eagles had severe cholinesterase inhibition, but without evidence of fonofos residues. During two winters from 1996 to 1998, 420 ha of potato fields, half of which had been treated the previous spring with fonofos and the remainder untreated, were searched weekly for evidence of wildlife mortality. Search efficiency was assessed with placed duck carcasses. Waterfowl outnumbered other species in field-use counts and comprised the greatest proportion of birds found dead. We found 211 wildlife remains, most scavenged; 35 intact carcasses were suitable for postmortem examination and/or toxicology analyses. Cholinesterase activity was assayed in brains of 18 waterfowl, five of which had severely depressed activity (average inhibition 74%; range, 69-78%). The gastrointestinal tract of a mallard found in a field treated with granular product contained 49 microg/g fonofos residues, linking waterfowl mortality with labelled use of the product. These findings demonstrate the risk of both primary and secondary poisoning by anticholinesterase insecticides where wildlife make intensive use of farmed fields.

A Teacher Research Experience: Immersion Into the World of Practicing Ocean Scientists

Professional development standards for science teachers encourage opportunities for intellectual professional growth, including participation in scientific research (NRC, 1996). Strategies to encourage the professional growth of teachers of mathematics and science include partnerships with scientists and immersion into the world of scientists and mathematicians (Loucks-Horsley, Love, Stiles, Mundry, & Hewson, 2003). A teacher research experience (TRE) can often offer a sustained relationship with scientists over a prolonged period of time. Research experiences are not a new method of professional development (Dubner, 2000; Fraser-Abder & Leonhardt, 1996; Melear, 1999; Raphael et al., 1999). Scientists serve as role models and "coaches" for teachers a practice which has been shown to dramatically increase the transfer of knowledge, skill and application to the classroom (Joyce & Showers, 2002). This study investigated if and how secondary teachers' beliefs about science, scientific research and science teaching changed as a result of participation in a TRE. Six secondary science teachers participated in a 12 day research cruise. Teachers worked with scientists, the ships' crew and other teachers conducting research and designing lessons for use in the classroom. Surveys were administered pre and post TRE to teachers and their students. Additionally, teachers were interviewed before, during and after the research experience, and following classroom observations before and after the research cruise. Teacher journals and emails, completed during the research cruise, were also analyzed. Results of the study highlight the use of authentic research experiences to retain and renew science teachers, the impact of the teachers' experience on students, and the successes and challenges of implementing a TRE during the academic year.

Implementation and impact of experiential learning in a graduate level teacher education program: An example from a Canadian universit

Full Text Available Teacher inquiry, in which teachers study their own professional practice, is currently a popular form of experiential learning that is considered a powerful tool to bring about effective change in teaching and learning. Little empirical evidence, however, exists to explain precisely if and how this pedagogical methodology moves teachers toward transformation of practice. Using grounded theory methodology, we examined twelve end of term graduate level learning portfolios and administered a survey to 336 in-service teachers enrolled in a two-year graduate diploma program in the Faculty of Education at Simon Fraser University, Canada. We found powerful evidence that our programs were highly impactful, with 94% of teachers reporting transformative learning within the second year of the program. Using portfolio data we examined the process of the teacher transformations. Our findings revealed that teachers’ abilities to interrogate their subjective-objective stance deepened their experiential learning. Using three case studies we exemplify how transformative pathways were formulated and conclude with a discussion of the implications of learning through experience, including the value of student-generated learning goals, continuous interfacing of theory and practice, seeing your ‘teaching’ through the eyes of your students/colleagues or parents, and the power of living your research question in the context of your own classroom and school setting. We end the paper on a cautionary note pointing out the vulnerability of programs of this nature in an era of accountability, standardization, quality control, and risk management all of which eclipse approaches that focus on authentic practical problems and student generated solutions.

This paper reports the achievement of the research and development on the hi-tech assembling sub-system. This system was studied by grouping the system into a seam sewing technology and a three-dimensional sewing technology. The former technology deals with the processes of seam sewing of the side of the left body part in a model wear, sew-up margin division, straightening, and back center seam sewing. The latter technology deals with the sleeve fitting process. Although these processes are the subject of automated system, it is difficult to automate the back collar sewing, shoulder sewing and front collar sewing after the back center seam sewing process to just before the sleeve fitting process. Therefore, these processes are processed by retrofitting and three-dimensional sewing devices, and a control computer to transmit, receive and control the information required for the devices. The utilizing conditions of the sub-system constituting devices and the component technologies are tabulated in a table. (NEDO)

The paper summarized the R and D of system management/control technology which is an element technology of an automatic sewing system by the Automatic Sewing System Technology Research Association. The effects were confirmed by experiments such as the inspection of dimensions of sewing parts using image processing technology, inspection of the surface state to examine if or not there are darts and pintucks, making and demonstration of the recognition treatment software for fitting patterns on the pocket with big cross stripes, strengthening of the function to determine processing position, etc. Improvement was added to 7 segment letters which becomes ID information so that 8mm letters could be read at a recognition rate of more than 95%. The information required for production plan was summarized after making it mutually connected. Further, a method was worked out for estimation of the standard time required for making the day schedule. Files for drawing-up the optimum process and for process control simulator were made by the expression peculiar to apparel. The framework of the interface was prepared to make the following clear: the integration of the process control use computer into the microcomputer for control of automatic machines such as devices and presses for sewing preparation, multi-functional sewing, assembly sewing, cloth handling/positioning, and the sharing of functions.

Full Text Available High-elevation red spruce [Picea rubens Sarg.]-Fraser fir [Abies fraseri (Pursh. Poir] forests in the Southern Appalachians currently receive large nitrogen (N inputs via atmospheric deposition (30 kg N ha�1 year�1 but have limited N retention capacity due to a combination of stand age, heavy fir mortality caused by exotic insect infestations, and numerous gaps caused by windfalls and ice storms. This study examined the magnitude and timing of the N fluxes into, through, and out of a small, first-order catchment in the Great Smoky Mountains National Park. It also examined the role of climatic conditions in causing interannual variations in the N output signal. About half of the atmospheric N input was exported annually in the streamwater, primarily as nitrate (NO3-N. While most incoming ammonium (NH4-N was retained in the canopy and the forest floor, the NO3-N fluxes were very dynamic in space as well as in time. There was a clear decoupling between NO3-N input and output fluxes. Atmospheric N input was greatest in the growing season while largest NO3-N losses typically occurred in the dormant season. Also, as water passed through the various catchment compartments, the NO3-N flux declined below the canopy, increased in the upper soil due to internal N mineralization and nitrification, and declined again deeper in the mineral soil due to plant uptake and microbial processing. Temperature control on N production and hydrologic control on NO3-N leaching during the growing season likely caused the observed inter-annual variation in fall peak NO3-N concentrations and N discharge rates in the stream.

Full Text Available Listeria monocytogenes, a foodborne pathogen that can cause listeriosis through the consumption of food contaminated with this pathogen. The ability of L. monocytogenes to survive in extreme conditions and cause food contaminations have become a major concern. Hence, routine microbiological food testing is necessary to prevent food contamination and outbreaks of foodborne illness. This review provides insight into the methods for cultural detection, enumeration and molecular identification of L. monocytogenes in various food samples. There are a number of enrichment and plating media that can be used for the isolation of L. monocytogenes from food samples. Enrichment media such as buffered Listeria Enrichment Broth (BLEB, Fraser broth and University of Vermont Medium (UVM Listeria enrichment broth are recommended by regulatory agencies such as FDA-BAM, USDA-FSIS and ISO. Many plating media are available for the isolation of L. monocytogenes, for instance, PALCAM, Oxford and other chromogenic media. Besides, reference methods like FDA-BAM, ISO 11290 method and USDA-FSIS method are usually applied for the cultural detection or enumeration of L. monocytogenes. MPN technique is applied for the enumeration of L. monocytogenes in the case of low level contamination. Molecular methods including polymerase chain reaction (PCR, multiplex polymerase chain reaction (mPCR, real-time/quantitative polymerase chain reaction (qPCR, nucleic acid sequence-based amplification (NASBA, loop-mediated isothermal amplification (LAMP, DNA microarray and Next Generation Sequencing (NGS technology for the detection and identification of L. monocytogenes are discussed in this review. Overall, molecular methods are rapid, sensitive, specific, time- and labour-saving. In future, there are chances for the development of new techniques for the detection and identification of foodborne with improved features.

Bedrock erosion in rivers sets the pace of landscape evolution, influences the evolution of orogens and determines the size, shape and relief of mountains. A variety of models link fluid flow and sediment transport processes to bedrock incision in canyons. The model components that represent sediment transport processes are increasingly well developed. In contrast, the model components being used to represent fluid flow are largely untested because there are no observations of the flow structure in bedrock canyons. Here we present a 524-kilometre, continuous centreline, acoustic Doppler current profiler survey of the Fraser Canyon in western Canada, which includes 42 individual bedrock canyons. Our observations of three-dimensional flow structure reveal that, as water enters the canyons, a high-velocity core follows the bed surface, causing a velocity inversion (high velocities near the bed and low velocities at the surface). The plunging water then upwells along the canyon walls, resulting in counter-rotating, along-stream coherent flow structures that diverge near the bed. The resulting flow structure promotes deep scour in the bedrock channel floor and undercutting of the canyon walls. This provides a mechanism for channel widening and ensures that the base of the walls is swept clear of the debris that is often deposited there, keeping the walls nearly vertical. These observations reveal that the flow structure in bedrock canyons is more complex than assumed in the models presently used. Fluid flow models that capture the essence of the three-dimensional flow field, using simple phenomenological rules that are computationally tractable, are required to capture the dynamic coupling between flow, bedrock erosion and solid-Earth dynamics.

A Distributed Snow Evolution Modeling System (SnowModel)

Liston, G. E.; Elder, K.

2004-12-01

A spatially distributed snow-evolution modeling system (SnowModel) has been specifically designed to be applicable over a wide range of snow landscapes, climates, and conditions. To reach this goal, SnowModel is composed of four sub-models: MicroMet defines the meteorological forcing conditions, EnBal calculates surface energy exchanges, SnowMass simulates snow depth and water-equivalent evolution, and SnowTran-3D accounts for snow redistribution by wind. While other distributed snow models exist, SnowModel is unique in that it includes a well-tested blowing-snow sub-model (SnowTran-3D) for application in windy arctic, alpine, and prairie environments where snowdrifts are common. These environments comprise 68% of the seasonally snow-covered Northern Hemisphere land surface. SnowModel also accounts for snow processes occurring in forested environments (e.g., canopy interception related processes). SnowModel is designed to simulate snow-related physical processes occurring at spatial scales of 5-m and greater, and temporal scales of 1-hour and greater. These include: accumulation from precipitation; wind redistribution and sublimation; loading, unloading, and sublimation within forest canopies; snow-density evolution; and snowpack ripening and melt. To enhance its wide applicability, SnowModel includes the physical calculations required to simulate snow evolution within each of the global snow classes defined by Sturm et al. (1995), e.g., tundra, taiga, alpine, prairie, maritime, and ephemeral snow covers. The three, 25-km by 25-km, Cold Land Processes Experiment (CLPX) mesoscale study areas (MSAs: Fraser, North Park, and Rabbit Ears) are used as SnowModel simulation examples to highlight model strengths, weaknesses, and features in forested, semi-forested, alpine, and shrubland environments.

The two most frequent microcytic anemias are beta-thalassemic trait (beta-TT) and iron deficiency anemia (IDA). Several discrimination indices have been proposed to distinguish between these two conditions. These indices are derived from several simple red blood cell indices, like red blood cell (RBC) count, mean cell volume, and RBC distribution width (RDW), as these are provided by electronic cell counters. The purpose of the study is to examine the diagnostic accuracy of six discrimination indices in the differentiation between IDA and beta-TT. The six discrimination indices that were examined were as follows: Mentzer Index (MI), Green & King Index (G&K), RDW Index (RDWI), England & Fraser Index (E&F), RDW, and RBC count. We calculated these indices on 373 patients (205 men, 168 women) with beta-TT and 120 patients (50 men, 70 women) with IDA, as well as their sensitivity, specificity, positive and negative prognostic value, efficiency, and Youden's index (YI). G&K shows the highest reliability, followed by E&F, RBC count, MI, and RDWI. On the contrary, RDW completely failed to differentiate between IDA and beta-TT. G&K proved to be the most reliable index as it had the highest sensitivity (75.06%), efficiency (80.12%), and YI (70.86%) for the detection of beta-TT. These six discrimination indices cannot be relied on for a safe differential diagnosis between beta-TT and IDA. They do have high specificity, but their sensitivity for the detection of beta-TT is not satisfactory. Consequently, they cannot be used neither as a screening tool for beta-TT because they could result in a significant number of false negative results.

Primary anophthalmia is a rare congenital malformation that affects 0.6/10,000 liveborn infants. It is usually associated with central nervous system malformations, aneuploidies, cytomegalovirus infection and mental retardation and it can also be part of genetic conditions such as Fraser, Goltz, Goldenhar, Waardenburg and Lenz syndromes. Neonatal prognosis depends on whether anophthalmia is an isolated malformation, or it is associated with other defects or part of a syndrome. A healthy 43-year-old woman, G4 P3 with three previous healthy children, was referred to our clinic for a routine obstetric ultrasound at 28 weeks' gestation. The fetal eye globes and lenses could not be seen on two-dimensional (2D) ultrasound, which led to the diagnosis of bilateral congenital anophthalmia. No other fetal malformations were detected. At 30 weeks' gestation, a three-dimensional (3D) ultrasound was performed using the rendering mode and "reverse face" view. Using this technique, the absence of both eye globes could be clearly seen through a "slit". 3D-ultrasound allowed the parents to better understand their child's problem and possible postnatal implications. Fetal magnetic resonance imaging (MRI) was also performed, to study the fetal cortex in more detail. This exam revealed right cerebral hemisphere sulci and gyri hypoplasia. At 41 1/7 weeks, she went into spontaneous labor and delivered vaginally a 3525 g male infant with Apgar scores of 9 and 10. Postnatal exams confirmed bilateral congenital anophthalmia. This is the first case report in the literature of prenatal diagnosis of bilateral anophthalmia using 3D "reverse face" view ultrasound and MRI. Copyright © 2012. Published by Elsevier B.V.

Human recreation alters behaviour profiles of non-breeding birds on open-coast sandy shores

Sandy beaches are primarily valued for their amenity and property values rather than for their ecological functions and properties. Some human usage of beaches potentially conflicts with the conservation and management of wildlife, such as beach-dwelling birds, on sandy shorelines. Because responses by birds to environmental change, including disturbance by humans, often involve behaviours that carry fitness costs, we quantify behaviour profiles of birds in relation to human occurrence along 200 km of sandy shoreline in Eastern Australia, including the large conservation area of Fraser Island. Disturbance to birds on these shores was considerable: 1) birds encountered motorized vehicles (cars, trucks, buses etc.) during 80% of focal bird observation bouts, 2) birds were flushed in over half (up to 86% in individual species) of all bouts, and 3) individuals spent, on average, one-third of their time on disturbance-related behaviours; this was particularly prevalent for Crested Terns (Thalasseus bergii) which were alert 42% of the time and spent 12% of their time escaping from human stimuli. Overall, this study demonstrated that motorized traffic is the prime agent of disturbance to birds on these beaches, resulting in frequent and time-consuming escape behaviours. These findings also emphasize that management of vehicle-based recreation on beaches needs to be re-aligned to meet conservation requirements in addition to providing leisure opportunities in National Parks and beyond; we identify some salient issue for this development: a) encouragement of social norms that promote environmentally benign beach use not involving motor vehicles, b) creation of spatial refuges for beach wildlife from traffic and other non-compatible uses, and c) investment in developing complementary management actions such as effective set-back distances.

Ion microprobe (SHRIMP) U-Pb zircon dating. Pb-Nd isotope tracer studies and major, trace and rare-earth element analyses have identified, for the first time. a Mesoproterozoic (1.2 Ga) quartz diorite intrusion in the central part of the Archaean Yilgarn Craton. Western Australia The quartz diorite is characterised by intergrowths of quartz and plagioclase, having low A/CNK (0 8). low K{sub 2}O (0.28 wt%), Ba (54 ppm), Rb (11 ppm), Sr (92 ppm), Pb (13 ppm), U (1.7 ppm) and Th (6 ppm) contents, high Nd (41 ppm), Sm (10.5 ppm), Zr (399 ppm). Nb (18.5 ppm). Y (57.5 ppm) and Sc (19 ppm) contents. a low Pb isotope two-stage model {mu} value (6.3), and a primitive initial e{sub Nd} value (+3.4) at 1.2 Ga. It is interpreted that the 1.2 Ga quartz diorite was derived from a predominantly mantle source, with minor crustal contamination, possibly from the surrounding Archaean monzogranites or their source region, during magma ascent. The age (1215 {+-} 11 Ma) of the intrusion overlaps with the timing of a major continental collisional orogeny in the Albany-Fraser Orogen, about 400km south, and is broadly coeval with the diamond-bearing Argyle lamproites in the east Kimberley Block. This study extends the history of granitoid magmatism in the central craton by more than 1.0 billion years (2.6 to 1.2 Ga), and has implications for isotopic data interpretations of tectonothermal events in the craton.

Such test bed allows the user to choose between two different options of development environments, to perform aerial and ground vehicles applications. On the one hand, it is possible to select an environment based on the VICON system and LabVIEW (National Instruments or robotics operating system platforms, which make use the Parrot AR.Drone software development kit or the Bebop_autonomy Driver to communicate with the unmanned vehicles. On the other hand, it is possible to employ a platform that uses the OptiTrack system and that allows users to develop their own applications, replacing AR.Drone’s original firmware with original code. We have developed four experimental setups to illustrate the use of the Parrot software development kit, the Bebop Driver (AutonomyLab, Simon Fraser University, British Columbia, Canada, and the original firmware replacement for performing a strategy that involves both ground and aerial vehicle tracking. Finally, in order to illustrate the effectiveness of the developed test bed for the implementation of advanced controllers, we present experimental results of the implementation of three consensus algorithms: static, adaptive, and neural network, in order to accomplish that a team of multiagents systems move together to track a target.

Multi-scale modeling of Puget Sound using an unstructured-grid coastal ocean model: from tide flats to estuaries and coastal waters

Yang, Zhaoqing; Khangaonkar, Tarang

2010-01-01

Water circulation in Puget Sound, a large complex estuary system in the Pacific Northwest coastal ocean of the United States, is governed by multiple spatially and temporally varying forcings from tides, atmosphere (wind, heating/cooling, precipitation/evaporation, pressure), and river inflows. In addition, the hydrodynamic response is affected strongly by geomorphic features, such as fjord-like bathymetry and complex shoreline features, resulting in many distinguishing characteristics in its main and sub-basins. To better understand the details of circulation features in Puget Sound and to assist with proposed nearshore restoration actions for improving water quality and the ecological health of Puget Sound, a high-resolution (around 50 m in estuaries and tide flats) hydrodynamic model for the entire Puget Sound was needed. Here, a threedimensional circulation model of Puget Sound using an unstructured-grid finite volume coastal ocean model is presented. The model was constructed with sufficient resolution in the nearshore region to address the complex coastline, multi-tidal channels, and tide flats. Model open boundaries were extended to the entrance of the Strait of Juan de Fuca and the northern end of the Strait of Georgia to account for the influences of ocean water intrusion from the Strait of Juan de Fuca and the Fraser River plume from the Strait of Georgia, respectively. Comparisons of model results, observed data, and associated error statistics for tidal elevation, velocity, temperature, and salinity indicate that the model is capable of simulating the general circulation patterns on the scale of a large estuarine system as well as detailed hydrodynamics in the nearshore tide flats. Tidal characteristics, temperature/salinity stratification, mean circulation, and river plumes in estuaries with tide flats are discussed.

Full Text Available Listeria and in particular Listeria monocytogenes is considered a ubiquitous foodborne pathogen which can lead listeriosis in human and animals. Listeriosis can be serious and may cause meningitis, septicemia and abortion in pregnant women. Although wastewater or sludge may contaminate foods of plant origin, there are no data on occurrence of Listeria spp. in wastewater and sludge in Iran. The purpose of current investigation was to study the occurrence of Listeria spp. in various samples of wastewater and sludge in Isfahan North wastewater treatment plant. Influent, effluent, raw sludge and dried sludge samples were collected from Isfahan North municipal wastewater treatment plant. L. monocytogenes were enumerated by a three–tube most probable number (MPN assay using enrichment Fraser broth. A total of 65 various samples from five step in 13 visits were collected. The presence of Listeria spp. also was determined using USDA procedure. Then, phenotypically identified L. monocytogenes were further confirmed by Polymerase Chain Reaction amplification. L. monocytogenes isolated from 76.9%, 38.5%, 84.6%, 69.2% and 46.2% of influent, effluent, raw sludge, stabilized sludge and dried sludge respectively. The efficiency of wastewater treatment processes, digester tank and drying bed in removal L. monocytogenes were 69.6%, 64.7% and 73.4% respectively. All phenotypically identified L. monocytogenes were further confirmed by Polymerase Chain Reaction. The results of present study have shown that Listeriaspp. and L. monocytogenes in particular, were present in wastewater treatment plant effluents and sludge at high level. The bacteria may spread on agriculture land and contaminate foods of plant origin. This may cause a risk of spreading disease to human and animals.

Retro-fitting of tank farm to comply with new environmental standards

Trans Mountain Enterprises transports jet fuel via an NPS 6 pipeline from refineries in the Vancouver area and the Company's marine terminal to a tank farm located at the Vancouver International Airport. The pipeline operates on a nearly continual basis and delivers product into tankage before releasing it to the airlines for distribution to the aircraft. Constructed in 1967 on Sea Island at the mouth of the Fraser River, the tank farm is situated on land leased from the Government of Canada and managed by the transportation agency, Transport Canada. The presence of wild life areas and a large salmon fishery combine to make the island a sensitive environmental area. The five above-ground storage tanks provide a combined storage volume of approximately 45,000 bbls. An operational spill at the tank farm in the fall of 1981 precipitated a two year clean up of the underlying soils and groundwater around the site. Although Trans Mountain assumed that the site was satisfactorily remediated by 1983 it was not until 1989 when Trans Mountain proposed an improvement to the tank bay containment area did it become aware of changing environmental and facility standards being adopted by Transport Canada. Following three years of negotiations with Transport Canada and their environmental advisors, Environment Canada, Trans Mountain completed a unique design to bring the site into compliance with Transport Canada's current standards for the Vancouver International Airport. The liner design was complicated by recent changes in the environmental standards for soil and groundwater at the site. These new changes were being adopted by Environment Canada during the design phase of this project

This paper describes the achievements in fiscal 1985 of developing an automatic sewing system. The automatic fabric inspection detects and marks automatically defects in cloth that may cause quality defects in sewn products. This information is transmitted so that corrective actions can be taken preventively, and the quality is assured. In order to avoid errors in shifts of defect positions caused by expansion and shrinkage of cloth in each process, a meter marking device was fabricated to allow the positional information to be corrected. Improvement was given on the visual defect detection equipment by using optical means. Cloth cutting is performed mainly by the high-speed laser cutting system, where the knife mesh system is adopted for complementary purpose. Discussions were given on operation method plans for the laser cutting machine. The process is executed sequentially on one belt conveyer shaped honeycomb. An ITV camera is moved on a robot to use the image data therefrom for matching the patterns on cloth. An information printing device was given a basic design, and the printing ink was developed. An information transmission format was set as an item common to different devices. The pitch times in each process were calculated to structure a factory automation network. (NEDO)

Full Text Available Nigel SB Rawson,1–3 John Adams4 1Eastlake Research Group, Oakville, ON, 2Canadian Health Policy Institute, Toronto, ON, 3Fraser Institute, Vancouver, BC, 4Canadian PKU and Allied Disorders Inc., Toronto, ON, Canada Abstract: In democratic societies, good governance is the key to assuring the confidence of stakeholders and other citizens in how governments and organizations interact with and relate to them and how decisions are taken. Although defining good governance can be debatable, the United Nations Development Program (UNDP set of principles is commonly used. The reimbursement recommendation processes of the Canadian Agency for Drugs and Technologies in Health (CADTH, which carries out assessments for all public drug plans outside Quebec, are examined in the light of the UNDP governance principles and compared with the National Institute for Health and Care Excellence system in England. The adherence of CADTH's processes to the principles of accountability, transparency, participatory, equity, responsiveness and consensus is poor, especially when compared with the English system, due in part to CADTH's lack of genuine independence. CADTH's overriding responsibility is toward the governments that "own," fund and manage it, while the agency’s status as a not-for-profit corporation under federal law protects it from standard government forms of accountability. The recent integration of CADTH’s reimbursement recommendation processes with the provincial public drug plans’ collective system for price negotiation with pharmaceutical companies reinforces CADTH's role as a nonindependent partner in the pursuit of governments’ cost-containment objectives, which should not be part of its function. Canadians need a national organization for evaluating drugs for reimbursement in the public interest that fully embraces the principles of good governance – one that is publicly accountable, transparent and fair and includes all stakeholders

Field characteristics, petrography, and geochronology of the Hohonu Batholith and the adjacent Granite Hill Complex, North Westland, New Zealand

Detailed geological mapping, petrography, geochemistry and geochronological studies in the Hohonu Batholith, North Westland, have identified 10 granitoid plutons emplaced during three intrusive episodes. The earliest episode is represented by a single dated Paleozoic pluton, Summit Granite (new) (381.2 ± 7.3 Ma), which is correlated with a discrete pulse of Mid-Late Devonian plutonism recognised in the Karamea Batholith. The undated Mount Graham Granite (new) is also likely to be Paleozoic, based on chemical and petrographic characteristics. The bulk of the batholith (seven plutons) was emplaced in the mid Cretaceous (114-109 Ma) and comprises two related, yet distinct, geochemical suites, which correlate with the previously defined Rahu Suite. The plutons identified are (from north to south): Pah Point Granite; Jays Creek Granodiorite (new); Uncle Bay Tonalite; Te Kinga Monzogranite; Deutgam Granodiorite; Turiwhate Granodiorite (new); and Arahura Granite (new). Mid-Cretaceous plutonism in the Western Province is considered to be the result of crustal thinning and extension following overthickening during collision of the Early Cretaceous Median Tectonic Zone volcanic arc. Late Cretaceous alkaline activity is represented by the emplacement of the A-type French Creek Granite at 1.7 ± 1.8 Ma, contemporaneous with intrusion of a major swarm of doleritic-lamprophyric dikes - the Hohonu Dike Swarm. These events correlate with the first appearance of oceanic crust in the Tasman Sea. The Granite Hill Complex is a suite of amphibolite facies gneisses occurring as an uplifted wedge between the Alpine Fault nd the Hohonu Batholith. These gneisses are considered to represent an extension of the Fraser Complex to the south. A detailed understanding of their geological affinities and history is yet to be established.

Multiple account benefit-cost evaluation of the Burrard Thermal Generating Plant

International Nuclear Information System (INIS)

2001-04-01

The government of British Columbia commissioned a multiple account benefit-cost analysis of the Burrard Thermal Generating Plant to ensure that the power production is in the economic and environmental interest of the province. The power plant consists of 6 natural gas-fired generating units with a combined capacity of 950 MW. It has been updated in recent years to reduce local emissions and to increase plant availability and reliability. Burrard has contributed in a major way to BC Hydro's net revenues, but there have been concerns that BC Hydro's purchases of natural gas for the power plant have contributed to the sharp increases in natural gas prices in 2001. There have also been concerns about air emissions from Burrard, including greenhouse gases and nitrous oxides. Historically, the plant has been beneficial, but this report will determine if it is in the provincial interest to continue operation of Burrard or to turn to alternative scenarios. The alternatives include constraining Burrard's output, or shutting it down and replacing it with other resources and repowering the plant with more efficient combined cycle gas turbine technology. In the constrained scenario, Burrard output and net exports are reduced. In the repowering scenario, investment and output at Burrard is increased. The financial consequences of these impacts are measured by their effect on the net system costs of meeting BC Hydro's load. The report demonstrated that it would not be in the overall interest of the province to constrain the operation of Burrard or shut it down. It was recommended that BC Hydro should review in detail the repowering option for Burrard, and that the government should consider imposing an emission charge reflecting the estimated damage costs associated with local pollutants generated at Burrard. The revenues would be used to fund offset measures in the Lower Fraser Valley airshed. 29 refs., 29 tabs., 3 appendices

This report summarizes progress in three years of field research designed to evaluate biological and chemical indicators of the current and future health of the Southern Appalachian spruce-fir ecosystem. The emphasis of this research has been on the identification and understanding of mechanisms through which current levels of acidic deposition are impacting ecosystem processes. The identification of these principal mechanisms and key biological indicators of change was designed to improve our capabilities to detect, monitor, and assess the effects of air quality regulations and attendant future air quality changes on ecosystem response. Individual research tasks focused on the following research areas: (1) the significance of foliar uptake of atmospheric sources of nitrogen in relationship to plant utilization of N from available soil reserves; (2) linkages between atmospheric inputs to the soil surface, solution chemistry, and decomposition in the upper organic soil horizons; (3) effects of soil solution chemistry on uptake of cations and aluminum by fine roots; and (4) the effects of varying rates of calcium supply on carbon metabolism of Fraser fir and red spruce, and the relationship between calcium levels in wood cells and integrity of wood formed in bole and branches. Each of the individual tasks was designed to focus upon a mechanism or process that we consider critical to understanding chemical and biological linkages. These linkages will be important determinants in understanding the basis of past and potential future responses of the high elevation Southern Appalachian Forest to acidic deposition and other co-occurring environmental stresses. This report contains (1) background and rationale for the research undertaken in 1992-94; (2) a summary of principal research findings; (3) publications from this research; and (4) characterization of data sets produced by this research which will be the basis of future research, analyses and/or publications.

Available data on biological variation of HbA1c revealed marked heterogeneity. We therefore investigated and estimated the components of biological variation for HbA1c in a group of healthy individuals by applying a recommended and strictly designed study protocol using two different assay methods. Each month, samples were derived on the same day, for three months. Four EDTA whole blood samples were collected from each individual (20 women, 9 men; 20-45 years of age) and stored at -80°C until analysis. HbA1c values were measured by both high performance liquid chromatography (HPLC) (Shimadzu, Prominence, Japan) and boronate affinity chromatography methods (Trinity Biotech, Premier Hb9210, Ireland). All samples were assayed in duplicate in a single batch for each assay method. Estimations were calculated according to the formulas described by Fraser and Harris. The within subject (CV(I))-between subject (CV(G)) biological variations were 1.17% and 5.58%, respectively for HPLC. The calculated CV(I) and CV(G) were 2.15% and 4.03%, respectively for boronate affinity chromatography. Reference change value (RCV) for HPLC and boronate affinity chromatography was 5.4% and 10.4% respectively and individuality index of HbA(1c) was 0.35 and 0.93 respectively. This study for the first time described the components of biological variation for HbA1c in healthy individuals by two different assay methods. Obtained findings showed that the difference between CV(A) values of the methods might considerably affect RCV. These data regarding biological variation of HbA(1c) could be useful for a better evaluation of HbA(1c) test results in clinical interpretation.
