    2004-07-01

    Selective demolition practices have not yet become popular in our country. Unlike conventional demolition practices, selective demolition helps to increase the amount of components to be reused or materials to be recycled. Thus, the percentage of demolition waste deposited in landfills can be reduced, and the production of recycled materials with optimum quality is fostered. Taking the case study of selective demolition carried out in the municipally of Lasarte-Oria (Basque Country-Spain) as its basis, this paper presents an economic and environmental analysis of the same. Likewise, the economic costs deriving from selective demolition are compared with analogous costs from conventional demolition with an aim to establishing the ideal frame supporting economically feasible selective demolition.

    Full Text Available Le paysage est de plus en plus perçu comme une ressource. À ce titre, il est nécessaire de trouver des instruments juridiques, politiques ou économiques susceptibles de gérer cette « ressource-paysage » sur le long terme. Le gouvernement suisse a introduit récemment l’instrument des parcs naturels régionaux, organisés selon le modèle français, dans sa législation de protection de la nature et du paysage. Une mise en regard des nouveaux parcs avec des structures de gestion beaucoup plus anciennes, les bourgeoisies et les corporations, permet de mettre en évidence les forces et les faiblesses de chacun de ces instruments dans leur contribution à résoudre les rivalités d’usage entre acteurs utilisant ou influençant la ressource paysage. Cette comparaison permet de formuler des recommandations pratiques concernant la gestion de cette ressource.The landscape is increasingly perceived as a resource. For this reason, it is necessary to find legal, political and economic instruments that will succeed in managing this “resource landscape” in the long term. The Swiss government recently introduced the instrument of regional nature parks into the legislation governing nature and landscape preservation; the proposed parks are organized on the basis of the French model. The examination of the new parks from the perspective of much older management structures, i.e. the civic municipalities (bourgeoisies and corporations, makes it possible to demonstrate the strengths and weaknesses of each of these instruments in their contribution to the resolution of use rivalries between actors who use or influence the resource landscape. This comparison also enables the formulation of practical recommendations regarding the management of this resource.

    Urban air quality is one of the key factors affecting human health. Turkey has transformed itself into an urban society over the last 30 years. At the same time, air pollution has become a serious impairment to health in many urban areas in the country. This is due to many reasons. In this study, a nonparametric evaluation was conducted of health effects that are triggered by urban air pollution. Niğde, the city which is the administrative centre of Nigde province was chosen of the effects of air pollution since, like many central Turkish cities, it is situated on a valley where atmospheric inversion occurs. In this paper, the relationship between ambient urban air quality, namely PM10 and sulphur dioxide (SO2), and human health, specifically asthma, during the winter season is examined. Air pollution data and asthma cases from 2006 to 2010 are covered in this study. The results of our study indicate that total asthma cases reported in Nigde between 2008 and 2010 were highly dependent on ambient SO2 concentration. More asthma cases were recorded when 30 μg m(-3) or higher SO2 was present in the ambient air than those recorded under cleaner ambient air conditions. Moreover, it was determined that in Nigde in 2010, asthma cases reported in males aged between 45 and 64 were closely correlated with ambient SO2 (α=0.05).

  3. Performance evaluation of an open-cathode PEM fuel cell stack under ambient conditions: Case study of United Arab Emirates

    International Nuclear Information System (INIS)

    2015-01-01

    Highlights: • Performance evaluation of open-cathode PEM fuel cell stacks with forced air-convection. • Stack performance can vary up to 40% from winter to summer. • Hot and arid condition leads to membrane drying and performance deterioration. • Anode humidification improves the stack performance up to 40% during summer. - Abstract: The open-cathode polymer electrolyte membrane (PEM) fuel cell stack has been a promising candidate as a sustainable energy conversion system for replacing fossil fuel-based energy conversion devices in portable and automotive applications. As the ambient air is directly used to provide both oxidant and cooling, the complex cooling loop can be avoided which reduces the complexity and cost. However, the stack performance is highly affected by ambient conditions, i.e., ambient temperature and humidity. In this study, the effect of monthly ambient air conditions (temperature and humidity) is evaluated with respect to the stack’s power production performance as well as thermal, water and gas management by employing a validated three-dimensional open-cathode PEM fuel cell stack model. The annual climate data from the hot and arid environment of Abu Dhabi, United Arab Emirates (UAE) are used as a case study. The objective is to develop a better fundamental understanding of the interactions of physical phenomena in a fuel cell stack, which can assist in improving the performance and operation of an open-cathode PEM fuel cell-powered vehicle. The results indicate that the stack performance can vary significantly (up to 40%) from winter to summer, especially at high operating currents, with significant changes in the stack temperature and the water content at the membrane. Moreover, the anode humidification results in a significant improvement in the stack performance (up to 40%) in hot and dry conditions. However, a careful balance has to be struck between the humidifier parasitic load and the stack power.

    Full Text Available Esta ponencia presenta una visión general del proyecto de Indicadores de Salud Ambiental, coordinado por la OMS a nivel internacional y liderado por el Centro de Investigación sobre el Síndrome del Aceite Tóxico y Enfermedades Raras (CISATER en España. En ella se describen los objetivos del proyecto, las gestiones realizadas y los resultados obtenidos durante la fase de viabilidad de este proyecto. El proyecto consiste en el establecimiento de un sistema de información sobre salud ambiental que permita desarrollar una vigilancia de los factores ambientales determinantes de los estados de salud, realizar comparaciones internacionales, elaborar políticas de acción, así como facilitar la comunicación con la ciudadanía. La OMS desarrolló una metodología para el desarrollo de estos indicadores dentro del marco conceptual de información ambiental DPSEEA (Fuerzas impulsoras, Presión, Estado, Exposición, Efecto, Acción y seleccionó un total de 55 indicadores (que incluyen 168 variables sobre 10 áreas de la salud ambiental. Durante la fase de viabilidad se predijo que podrían obtenerse el 89% de los indicadores. Sin embargo la recolección de los datos supuso muchas dificultades debido a la incompatibilidad de algunas variables en los sistemas de información españoles con las variables definidas por la OMS. A nivel de gestión del proyecto, la mayor dificultad radica en la disparidad de responsabilidades en materia de medio ambiente y salud entre las instituciones españolas. Además de la aportación técnica a la salud ambiental en España, un valor añadido de este proyecto ha sido el establecimiento de líneas de colaboración estrechas con los responsables de los diferentes Ministerios implicados.

    Full Text Available Natural hazards do have impacts on development. Of heavy consequences on both the human life and the economic development these impacts are critical in most of the Caribbean islands in general and specifically in Haiti. Thus, there is an urgent need to implement strategies aiming at reducing risk for lessening losses. By implementing well designed risk management strategies vulnerability can be reduced, and as a consequence, investment and employment can be protected. Even so preparedness to sustainable development is at the global Agenda, with regards to the specific case of Haiti, we assume that, at present, the country is not at all involved in such a long run strategy. Government attention is focused on immediate urgencies to be solved. By questioning the particular case of tourism, we show the positive impact of risk management strategies on growth using a Cost-Benefit Analysis (CBA.Les catastrophes naturelles ont sans conteste des impacts sur le développement. Ces derniers, qui occasionnent de lourdes conséquences à la fois sur la vie humaine et le développement économique, sont préjudiciables dans la plupart des îles des Caraïbes et plus particulièrement en Haïti. Ainsi, il devient urgent de mettre en œuvre des stratégies visant à réduire les risques afin de minimiser les pertes occasionnées. En établissant des stratégies de gestion des risques bien conçues, la vulnérabilité des pays peut être réduite, et, par conséquent, l'investissement et l'emploi protégés.

    There is growing interest in the association between ambient air pollution and stroke, but few studies have investigated the association in developing countries. The primary objective of this study was to examine the association between levels of ambient air pollutants and hospital admission for stroke in China. A time-stratified case-crossover analysis was conducted between 2014 and 2015 in 14 large Chinese cities among 200,958 ischemic stroke and 41,746 hemorrhagic stroke hospitalizations. We used conditional logistic regression to estimate the percentage changes in stroke admissions in relation to interquartile range increases in air pollutants. Air pollution was positively associated with ischemic stroke. A difference of an interquartile range of the 6-day average for particulate matter less than 10 μm in aerodynamic diameter, sulfur dioxide, nitrogen dioxide, carbon monoxide, and ozone corresponded to 0.7% (95% CI: 0%, 1.4%), 1.6% (95% CI: 1.0%, 2.3%), 2.6% (95% CI: 1.8%, 3.5%), 0.5% (95% CI: -0.2%, 1.1%), and 1.3% (95% CI: 0.3%, 2.3%) increases in ischemic stroke admissions, respectively. For hemorrhagic stroke, we observed the only significant association in relation to nitrogen dioxide on the current day (percentage change: 1.6%; 95% CI: 0.3%, 2.9%). Our findings contribute to the limited scientific literature concerning the effect of ambient air pollution on stroke in developing countries. Our findings may have significant public health implications for primary prevention of stroke in China. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Background: Environmental determinants of appendicitis are poorly understood. Past work suggests that air pollution may increase the risk of appendicitis. Objectives: We investigated whether ambient ground-level ozone (O3) concentrations were associated with appendicitis and whether these associations varied between perforated and nonperforated appendicitis. Methods: We based this time-stratified case-crossover study on 35,811 patients hospitalized with appendicitis from 2004 to 2008 in 12 Canadian cities. Data from a national network of fixed-site monitors were used to calculate daily maximum O3 concentrations for each city. Conditional logistic regression was used to estimate city-specific odds ratios (ORs) relative to an interquartile range (IQR) increase in O3 adjusted for temperature and relative humidity. A random-effects meta-analysis was used to derive a pooled risk estimate. Stratified analyses were used to estimate associations separately for perforated and nonperforated appendicitis. Results: Overall, a 16-ppb increase in the 7-day cumulative average daily maximum O3 concentration was associated with all appendicitis cases across the 12 cities (pooled OR = 1.07; 95% CI: 1.02, 1.13). The association was stronger among patients presenting with perforated appendicitis for the 7-day average (pooled OR = 1.22; 95% CI: 1.09, 1.36) when compared with the corresponding estimate for nonperforated appendicitis [7-day average (pooled OR = 1.02, 95% CI: 0.95, 1.09)]. Heterogeneity was not statistically significant across cities for either perforated or nonperforated appendicitis (p > 0.20). Conclusions: Higher levels of ambient O3 exposure may increase the risk of perforated appendicitis. PMID:23842601

    Preventing suicide is a global imperative. Although the effects of social and individual risk factors of suicide have been widely investigated, evidence of environmental effects of exposure to air pollution is scarce. We investigated the effects of ambient air pollution on suicide mortality in Guangzhou, China during 2003-2012. A conditional logistic regression analysis with a time-stratified case-crossover design was performed to assess the effects of daily exposure to three standard air pollutants, including particulate matter less than 10 μm in aerodynamic diameter (PM10), sulphur dioxide (SO2) and nitrogen dioxide (NO2), on suicide mortality, after adjusting for the confounding effects of daily mean temperature, relative humidity, atmospheric pressure and sunshine duration. Further analyses were stratified by season, gender, age group, educational attainment and suicide type. Between 2003 and 2012, there were a total of 1 550 registered suicide deaths in Guangzhou. A significant increase in suicide risk were associated with interquartile-range increases in the concentration of air pollutant, with an odds ratio of 1.13 (95 % confidence interval (CI): 1.01, 1.27) and 1.15 (95 % CI: 1.03, 1.28) for PM10 and NO2 at lag 02, and 1.12 (95 % CI: 1.02, 1.23) for SO2 at lag 01, respectively. The suicide risks related to air pollution for males and people with high education level were higher than for females and those with low education level, respectively. Significant air pollution effects were found on violent suicide mortality and in cool season but not on non-violent suicide mortality or in warm season. Suicide risk was positively associated with ambient air pollution levels. This finding would provide important information for the health impact assessment of air pollution and for the development of effective strategies and interventions for the prevention of suicide.

    Full Text Available Abstract Introduction Clothing can be a cause of occupational dermatitis. Frequent causes of clothing-related dermatological problems can be the fabric itself and/or chemical additives used in the laundering process, friction from certain fabrics excessively rubbing the skin, or heat retention from perspiration-soaked clothing in hot working environments. To the best of our knowledge, these are the first reported cases of miliaria rubra associated with prolonged use of flame resistant clothing in the medical literature. Case presentation We report 18 cases (14 men and 4 women, with an age range of 19 to 37 years of moderate to severe skin irritation associated with wearing flame resistant clothing in hot arid environments (temperature range: 39 to 50°C, 5% to 25% relative humidity. We describe the medical history in detail of a 23-year-old Caucasian woman and a 31-year-old African-American man. A summary of the other 16 patients is also provided. Conclusions These cases illustrate the potential serious nature of miliaria with superimposed Staphylococcus infections. All 18 patients fully recovered with topical skin treatment and modifications to their dress ensemble. Clothing, in particular blend fabrics, must be thoroughly laundered to adequately remove detergent residue. While in hot environments, individuals with sensitive skin should take the necessary precautions such as regular changing of clothing and good personal hygiene to ensure that their skin remains as dry and clean as possible. It is also important that they report to their health care provider as soon as skin irritation or rash appears to initiate any necessary medical procedures. Miliaria rubra can take a week or longer to clear, so removal of exposure to certain fabric types may be necessary.

    There are several plausible mechanisms whereby either short or long term exposure to pollution can increase the risk of stroke. Over the last decade, several studies have reported associations between short-term (day-to-day) increases in ambient air pollution and stroke. The findings from a smaller number of studies that have looked at long-term exposure to air pollution and stroke have been mixed. Most of these epidemiological studies have assigned exposure to air pollution based on place of residence, but these assignments are typically based on relatively coarse spatial resolutions. To date, few studies have evaluated medium-term exposures (i.e, exposures over the past season or year). To address this research gap, we evaluated associations between highly spatially resolved estimates of ambient nitrogen dioxide (NO2), a marker of traffic pollution, and emergency department visits for stroke in Edmonton, Canada. This was a case-control study with cases defined as those who presented to an Edmonton area hospital emergency department between 2007 and 2009 with an acute ischemic stroke, hemorrhagic stroke, or transient ischemic attack. Controls were patients who presented to the same emergency departments for lacerations, sprains, or strains. A land-use regression model provided estimates of NO2 that were assigned to the place of residence. Logistic regression methods were used to estimate odds ratios for stroke in relation to an increase in the interquartile range of NO2 (5 ppb), adjusted for age, sex, meteorological variables, and neighborhood effects. The study included 4,696 stroke (cases) and 37,723 injury patients (controls). For all strokes combined, there was no association with NO2. Namely, the odds ratio associated with an interquartile increase in NO2 was 1.01 (95% confidence interval {CI}: 0.94-1.08). No associations were evident for any of the stroke subtypes examined. When combined with our earlier work in Edmonton, our findings suggest that day

    Full Text Available Complex landscape management instruments based on a dynamic, innovative land-conservation paradigm and spatial zoning to provide for graded intensity of protection and human use are being implemented in the newer generation of biosphere reserves and biosphere parks. The multifunctionality of these exemplary landscapes with sustainable development is a great challenge; it also offers considerable potential for conflict. This paper intends to demonstrate the extent to which multifunctionality has been realised in the alpine Großes Walsertal Biosphere Park, and how the local population perceive the quality of their park five years after it was created. Landscape management efforts in the Großes Walsertal were monitored by accompanying regional-economic and perceptional studies, resulting in a discussion of required future actions.Des instruments complexes de gestion du paysage, fondés sur un paradigme dynamique et innovant de conservation ainsi que sur un zonage de l’espace visant à réguler la protection du territoire et son utilisation par l’homme, ont été mis en œuvre dans la dernière génération de réserves de biosphère et de parcs. La multifonctionnalité de ces paysages exemplaires du développement durable constitue un défi majeur, mais représente également une importante source de conflits. L’objectif de cet article est de démontrer dans quelle mesure la notion de multifonctionnalité a été appliquée à la réserve de biosphère alpine de Grosse Walsertal et d’évaluer comment la population locale perçoit la qualité de son parc, cinq ans après sa création. Les efforts de gestion du paysage dans la réserve de Grosse Walsertal ont été évalués par des études économiques régionales et par des enquêtes de perception, à l’origine d’un débat sur les actions futures à mettre en place.

    Given the double jeopardy of global increases in rates of obesity and climate change, it is increasingly important to recognise the dangers posed to diabetic patients during periods of extreme weather. We aimed to characterise the associations between ambient temperature and general medical practitioner consultations made by a cohort of type-2 diabetic patients. Evidence on the effects of temperature variation in the primary care setting is currently limited. Case-crossover analysis of 4,474,943 consultations in England during 2012-2014, linked to localised temperature at place of residence for each patient. Conditional logistic regression was used to assess associations between each temperature-related consultation and control days matched on day-of-week. There was an increased odds of seeking medical consultation associated with high temperatures: Odds ratio (OR) = 1.097 (95% confidence interval = 1.041, 1.156) per 1 °C increase above 22 °C. Odds during low temperatures below 0 °C were also significantly raised: OR = 1.024 (1.019, 1.030). Heat-related consultations were particularly high among diabetics with cardiovascular comorbidities: OR = 1.171 (1.031, 1.331), but there was no heightened risk with renal failure or neuropathy comorbidities. Surprisingly, lower odds of heat-related consultation were associated with the use of diuretics, anticholinergics, antipsychotics or antidepressants compared to non-use, especially among those with cardiovascular comorbidities, although differences were not statistically significant. Type-2 diabetic patients are at increased odds of medical consultation during days of temperature extremes, especially during hot weather. The common assumption that certain medication use heightens the risk of heat illness was not borne-out by our study on diabetics in a primary care setting and such advice may need to be reconsidered in heat protection plans.

  18. Ambient noise as the new source for urban engineering seismology and earthquake engineering: a case study from Beijing metropolitan area

    2014-02-01

    In highly populated urban centers, traditional seismic survey sources can no longer be properly applied due to restrictions in modern civilian life styles. The ambient vibration noise, including both microseisms and microtremor, though are generally weak but available anywhere and anytime, can be an ideal supplementary source for conducting seismic surveys for engineering seismology and earthquake engineering. This is fundamentally supported by advanced digital signal processing techniques for effectively extracting the useful information out from the noise. Thus, it can be essentially regarded as a passive seismic method. In this paper we first make a brief survey of the ambient vibration noise, followed by a quick summary of digital signal processing for passive seismic surveys. Then the applications of ambient noise in engineering seismology and earthquake engineering for urban settings are illustrated with examples from Beijing metropolitan area. For engineering seismology the example is the assessment of site effect in a large area via microtremor observations. For earthquake engineering the example is for structural characterization of a typical reinforced concrete high-rise building using background vibration noise. By showing these examples we argue that the ambient noise can be treated as a new source that is economical, practical, and particularly valuable to engineering seismology and earthquake engineering projects for seismic hazard mitigation in urban areas.

    For several years, agricultural and nuclear professionals in France have been working on how to manage the agricultural situation in the event of a nuclear accident. This work resulted in measures at both the national (Aube nuclear safety exercises in 2003, INEX3 in 2005) and international levels (EURATOM Programmes). Following on from the European FARMING (FP5) and EURANOS (FP6) works, ACTA', IRSN and six agricultural technical institutes which are specialized in agricultural production and processing network (arable crop [especially cereals, maize, pulses, potatoes and forage crops], fruits and vegetables, vine and wine, livestock farming [cattle, sheep, goats, pigs, poultry]), created a resource adapted to the French context: the Decision-aiding Tool for the Management of Agriculture in case of a Nuclear Accident. Devised for the Ministry of Agriculture services supporting state officials in a radiation emergency, this manual focuses on the early phase following the accident when the state of emergency would make discussion on countermeasures with a large stakeholder panel impossible. Supported by the Ministry of Agriculture and Fisheries and the French Nuclear Safety Authority, this project increased knowledge of post-accident management strategies and made an important contribution to the national think tank set up within the framework of the French Steering Committee for managing the post-event phase of a nuclear accident (CODIRPA). This article describes how the manual evolved throughout the project and the development of new resources. (authors)

    Integrated analysis of water management incorporates a great range of dimensions and aspects involved in the management of a water system. Lately, these kind of studies have become numerous because they allow getting a holistic knowledge and they also help managers with the decision making process. Nevertheless, there is not yet a general methodology for tackling this type of studies and there is a big opened field concerning the tools and techniques application. This paper establishes a methodology, which can be extrapolated to other case studies, and a practical procedure for the integrated analysis of groundwater management. This analysis starts with the identification and conceptualization of the hydric problematic. Then, a second phase is focused on the development of sectorial and detailed studies. The third phase is the building of the Decision Support System (DSS) based on the results from the sectorial studies. This research develops and proposes the application of a stochastic DSS based on Object-Oriented Bayesian Networks (OOBNs) that allows incorporating a huge range of aspects such as hydrogeological, socioeconomic and environmental, among others. The last phase of the procedure is the simulation of water management scenarios through the DSS. This allows comparing and quantifying the impacts generated by three water management interventions which have been proposed previously. The first scenario establishes the continuation of the current situation, the second scenario is made up of for several water management interventions which are the incoming of external water resources, the purchase of water rights and a reduction of the water demand; finally, the third scenario implies to reach the equilibrium in the aquifer water budgets.

    The position towards the environment of the local organizations has envolved parallely to the restlessness of the society in general, taking every time a greater importance in this matter. From the municipal point of view, the management of the environment is not just a mere idea of protection of the nature or of certain forms of natural life in danger; now, the environmental management includes more complex aspects, like the balanced management of the natural resources and the general aim of the quality of life. The City councils, in their paper of public institutions, have much to say like centers where a great part of the life and activity of the population is developed, and the physical and geographic frame where the environmental problems have their seat.

    Goyal, S K; Ghatge, S V; Nema, P; M Tamhane, S

    2006-08-01

    Air pollution has become a growing problem in megacities and large urban areas through out the globe, and transportation is recognized as the major source of air pollution in many cities, especially in developing countries. Contribution of automobiles is reported in the range of 40 to 80% of the total air pollution. The challenge facing megacities is how to reduce the adverse environmental impacts and other negative effects of transportation without giving up the benefits of mobility. The dilemma becomes most pressing under conditions of rapid urban growth, which is likely to increase travel demand significantly. The paper is aimed at understanding the problem of vehicular pollution vis-a-vis ambient air quality for a highly traffic affected megacity, Delhi, wherein, the contribution of transport sector was estimated to be as high as 72%. An effort has been made to review and evaluate the benefits (in terms of improved air quality) of the technological interventions/policies adopted for vehicular pollution control in Delhi. It also highlights the outcome of the efforts and suggests further improvements thereon. The importance of public participation and awareness are also discussed. The paper focuses on deriving the benefits of the implementation of management strategies, supported by scientific and technical data/interpretation, so that the people can realize and participate in the government's endeavor for clean city drive in a more effective manner.

    Full Text Available Abstract Background While several studies have investigated the effects of short-term air pollution on cardiovascular disease, less is known about its effects on cerebrovascular disease, including stroke and transient ischaemic attack (TIA. The aim of the study was to assess the effects of short-term variation in air pollutants on the onset of TIA and minor stroke. Methods We performed secondary analyses of data collected prospectively in the North West of England in a multi-centre study (NORTHSTAR of patients with recent TIA or minor stroke. A case - crossover study was conducted to determine the association between occurrence of TIA and the concentration of ambient PM10 or gaseous pollutants. Results A total of 709 cases were recruited from the Manchester (n = 335 and Liverpool (n = 374 areas. Data for the Manchester cohort showed an association between ambient nitric oxide (NO and risk of occurrence of TIA and minor stroke with a lag of 3 days (odds ratio 1.06, 95% CI: 1.01 – 1.11, whereas negative association was found for the patients from Liverpool. Effects of similar magnitude, although not statistically significant, were generally observed with other pollutants. In a two pollutant model the effect of NO remained stronger and statistically significant when analysed in combination with CO or SO2, but was marginal in combination with NO2 or ozone and non-significant with PM10. There was evidence of effect modification by age, gender and season. Conclusions Our data suggest an association between NO and occurrence of TIA and minor stroke in Greater Manchester.

  6. Environment and sustainable development: The Yurimaguas City case Ambiente y desarrollo sostenible: el caso de la ciudad de Yurimaguas

    2010-12-01

    Full Text Available Humanity is looking for solutions to the environmental degradation problem, which is generated by the economic and demographic growth, the indiscriminate use of resources, deforestation and pollution. The «sustainable development» concept, which considers social, economical and environmental aspects, was created twenty years ago, but it is still not producing the desired effects, and its application generates discussion, propositions and alternatives. As a geographer, I am interested especially in two aspects, which I consider, could lead the city development to sustainability: 1. adjust the development to the advantages and limitations of the natural media of the region where the city is located, and 2. that the urban activities do not transfer the costs and environmental problems to the surroundings of the city and to the future generations.In this paper I’ll try to put both postulations taking as an example the Yurimaguas city development. This city, located at a strategic point in the route between two oceans, has a past and a future linked to the conditions of the natural environment. The paper has an introduction where the theoretical aspects of both postulations are explained, then comes an analysis and discussion of the relationship between the natural environment and development of the Yurimaguas city, and finally some propositions are suggested to improve the quality of the city environment in order to lead it to a sustainable development.La humanidad entera busca una solución a los problemas de la degradación del ambiente, generada por el crecimiento económico y demográfico, el uso indiscriminado de los recursos, la deforestación y la contaminación.

    Since motor vehicles are a major air pollution source, urban designs that decrease private automobile use could improve air quality and decrease air pollution health risks. Yet, the relationships among urban form, air quality, and health are complex and not fully understood. To explore these relationships, we model the effects of three alternative development scenarios on annual average fine particulate matter (PM2.5 ) concentrations in ambient air and associated health risks from PM2.5 exposure in North Carolina's Raleigh-Durham-Chapel Hill area. We integrate transportation demand, land-use regression, and health risk assessment models to predict air quality and health impacts for three development scenarios: current conditions, compact development, and sprawling development. Compact development slightly decreases (-0.2%) point estimates of regional annual average PM2.5 concentrations, while sprawling development slightly increases (+1%) concentrations. However, point estimates of health impacts are in opposite directions: compact development increases (+39%) and sprawling development decreases (-33%) PM2.5-attributable mortality. Furthermore, compactness increases local variation in PM2.5 concentrations and increases the severity of local air pollution hotspots. Hence, this research suggests that while compact development may improve air quality from a regional perspective, it may also increase the concentration of PM2.5 in local hotspots and increase population exposure to PM2.5 . Health effects may be magnified if compact neighborhoods and PM2.5 hotspots are spatially co-located. We conclude that compactness alone is an insufficient means of reducing the public health impacts of transportation emissions in automobile-dependent regions. Rather, additional measures are needed to decrease automobile dependence and the health risks of transportation emissions. © 2014 Society for Risk Analysis.

    Full Text Available Ambient Intelligence promises to transform current spaces into electronic environments that are responsive, assistive and sensitive to human presence. Those electronic environments will be fully populated with dozens, hundreds or even thousands of connected devices that share information and thus become intelligent. That massive wave of electronic devices will also invade everyday objects, turning them into smart entities, keeping their native features and characteristics while seamlessly promoting them to a new class of thinking and reasoning everyday objects. Although there are strong expectations that most of the users’ needs can be fulfilled without their intervention, there are still situations where interaction is required. This paper presents work being done in the field of human-computer interaction, focusing on smart home environments, while being a part of a larger project called Aging Inside a Smart Home. This initiative arose as a way to deal with a large scourge of our country, where lots of elderly persons live alone in their homes, often with limited or no physical mobility.

    Campylobacter spp. is a commonly reported food-borne disease with major consequences for morbidity. In conjunction with predicted increases in temperature, proliferation in the survival of microorganisms in hotter environments is expected. This is likely to lead, in turn, to an increase in contamination of food and water and a rise in numbers of cases of infectious gastroenteritis. This study assessed the relationship of Campylobacter spp. with temperature and heatwaves, in Adelaide, South Australia. We estimated the effect of (i) maximum temperature and (ii) heatwaves on daily Campylobacter cases during the warm seasons (1 October to 31 March) from 1990 to 2012 using Poisson regression models. There was no evidence of a substantive effect of maximum temperature per 1 °C rise (incidence rate ratio (IRR) 0·995, 95% confidence interval (95% CI) 0·993-0·997) nor heatwaves (IRR 0·906, 95% CI 0·800-1·026) on Campylobacter cases. In relation to heatwave intensity, which is the daily maximum temperature during a heatwave, notifications decreased by 19% within a temperature range of 39-40·9 °C (IRR 0·811, 95% CI 0·692-0·952). We found little evidence of an increase in risk and lack of association between Campylobacter cases and temperature or heatwaves in the warm seasons. Heatwave intensity may play a role in that notifications decreased with higher temperatures. Further examination of the role of behavioural and environmental factors in an effort to reduce the risk of increased Campylobacter cases is warranted.

    Full Text Available This study is intended to explore a complementary relationship between instructional systems design (ISD and project management in an attempt to build a plausible case for integrating project management as a distinct course in the core of the graduate instructional systems design programs. It is argued that ISD and project management should form a symbiosis from a curriculum perspective, in a hope for the prepared instructional designers to create values for customers. An integrated view of ISD and project management is proposed, using three concepts of project management as a reasonable bridge for the integration. Challenges for the proposed view in this position paper are also stated. Cette étude explore la complémentarité de la conception de matériel pédagogique et de la gestion de projets en vue de justifier l’intégration de la gestion de projets à titre de cours distinct au cœur des programmes des cycles supérieurs en conception de matériel pédagogique. L’étude fait valoir l’intérêt d’une symbiose de la conception de matériel pédagogique et de la gestion de projets du point de vue du programme d’études, afin de préparer les concepteurs pédagogiques formés à créer une plus-value pour les clients. Elle propose une vision intégrée de la conception de matériel pédagogique et de la gestion de projets fondée sur trois concepts de la gestion de projets favorisant une telle intégration.

    The ambient air quality (AAQ) assessment was undertaken in Sukinda Valley, the chromite hub of India. The possible correlations of meteorological variables with different air quality parameters (PM10, PM2.5, SO2, NO2 and CO) were examined. Being the fourth most polluted area in the globe, Sukinda Valley has always been under attention of researchers, for hexavalent chromium contamination of water. The monitoring was carried out from December 2013 through May 2014 at six strategic locations in the residential and commercial areas around the mining cluster of Sukinda Valley considering the guidelines of Central Pollution Control Board (CPCB). In addition, meteorological parameters viz., temperature, relative humidity, wind speed, wind direction and rainfall, were also monitored. The air quality data were subjected to a general linear model (GLM) coupled with one-way analysis of variance (ANOVA) test for testing the significant difference in the concentration of various parameters among seasons and stations. Further, a two-tailed Pearson's correlation test helped in understanding the influence of meteorological parameters on dispersion of pollutants in the area. All the monitored air quality parameters varied significantly among the monitoring stations suggesting (i) the distance of sampling location to the mine site and other allied activities, (ii) landscape features and topography and (iii) meteorological parameters to be the forcing functions. The area was highly polluted with particulate matters, and in most of the cases, the PM level exceeded the National Ambient Air Quality Standards (NAAQS). The meteorological parameters seemed to play a major role in the dispersion of pollutants around the mine clusters. The role of wind direction, wind speed and temperature was apparent in dispersion of the particulate matters from their source of generation to the surrounding residential and commercial areas of the mine.

    Full Text Available Il conseguimento di elevati livelli di sicurezza in cantiere è influenzato dalle decisioni assunte in fase di programmazione. Permangono tuttavia i pericoli generati dalla concomitanza di fattori impredicibili, che possono essere mitigati dall’adozione di sistemi di monitoraggio automatico. Questo contributo presenterà tre sistemi: un sistema proattivo adatto a prevenire rischi di caduta di materiali dall’alto; un sistema di monitoraggio in tempo reale a bassa infrastrutturazione per segnalare interferenze pericolose tra le squadre; un sistema di controllo in tempo reale della concentrazione di particolato fi ne. Tutti questi sistemi adottano tecnologie avanzate e implementano logiche per valutare il livello di rischio contingente. Si mostra perciò come l’impiego di tecnologie ICT può supportare la gestione della sicurezza.

    managers in public administrations is suggested, as a further step in the development of a proper management of ungulates and other wildlife. Scientific research on ungulates in Italy was, in the last decade, quite uneven both in the species and in the disciplines chosen. There is a clear opportunistic approach to subjects, that often has no link with the real necessities of wildlife management. The development of long term studies is suggested, together with a more efficient coordination among scientist in the choice of the research subjects. Last but not least a more efficient founding mechanisms is needed in order to avoid money waste and to promote serious research programmes. Riassunto Gli Ungulati nel nostro Paese hanno proseguito, nell'ultimo decennio, l'espansione dei loro areali già iniziata nel decennio precedente e, per quanto i dati disponibili possono testimoniare, della loro consistenza. Tale tendenza è particolarmente chiara nel Centro-Nord, mentre nell'area meridionale il processo di sviluppo di popolamenti di ungulati delle diverse specie è rallentato se non assente, sia pure con notevoli eccezioni come la Sardegna dove, grazie ad un'opportuna politica di reintroduzioni, il Cervo sardo (Cervus elaphus corsicanus sta tornando nelle quattro province dell'isola. In questo quadro generale deve essere ricordato il ruolo rilevante dell'aumento degli ungulati nel favorire l'espansione dei grandi predatori, in particolare del Lupo (Canis lupus in ampi settori del paese. La gestione degli ungulati ha anch'essa subito una positiva evoluzione durante l'ultimo decennio sebbene persistano forti differenze fra Centro-Nord e Sud. Reintroduzioni di molte specie, effettuate con procedure nel complesso più corrette di quelle eseguite nel passato, hanno contribuito a colmare le lacune della distribuzione naturale di molte specie. Le statistiche d'abbattimento disponibili hanno dimensioni che suggeriscono un'accresciuta importanza degli

  6. Associations between ambient air pollution and daily mortality in a cohort of congestive heart failure: Case-crossover and nested case-control analyses using a distributed lag nonlinear model.

    Persons with congestive heart failure may be at higher risk of the acute effects related to daily fluctuations in ambient air pollution. To meet some of the limitations of previous studies using grouped-analysis, we developed a cohort study of persons with congestive heart failure to estimate whether daily non-accidental mortality were associated with spatially-resolved, daily exposures to ambient nitrogen dioxide (NO 2 ) and ozone (O 3 ), and whether these associations were modified according to a series of indicators potentially reflecting complications or worsening of health. We constructed the cohort from the linkage of administrative health databases. Daily exposure was assigned from different methods we developed previously to predict spatially-resolved, time-dependent concentrations of ambient NO 2 (all year) and O 3 (warm season) at participants' residences. We performed two distinct types of analyses: a case-crossover that contrasts the same person at different times, and a nested case-control that contrasts different persons at similar times. We modelled the effects of air pollution and weather (case-crossover only) on mortality using distributed lag nonlinear models over lags 0 to 3 days. We developed from administrative health data a series of indicators that may reflect the underlying construct of "declining health", and used interactions between these indicators and the cross-basis function for air pollutant to assess potential effect modification. The magnitude of the cumulative as well as the lag-specific estimates of association differed in many instances according to the metric of exposure. Using the back-extrapolation method, which is our preferred exposure model, we found for the case-crossover design a cumulative mean percentage changes (MPC) in daily mortality per interquartile increment in NO 2 (8.8 ppb) of 3.0% (95% CI: -0.9, 6.9%) and for O 3 (16.5 ppb) 3.5% (95% CI: -4.5, 12.1). For O 3 there was strong confounding by weather

    Street canyons are vulnerable to air pollution mainly caused by vehicle emissions, which are therefore closely related to pedestrians' health. Previous studies have showed that air quality in street canyons is associated with street morphology, though the majority of them have focused on idealized street models. This paper attempts to investigate the relationship of street morphology to air quality for 6 irregular real-world cases selected from America, Europe, and China, i.e. Manhattan, Paris, Barcelona, Berlin, London and Nanjing. Each street is analyzed as a set of slices to propose a couple of morphology indices for quantitatively assessing the actual street morphology. Pollutant transport rate of mean flows and turbulent diffusion, net escape velocity and age of air are obtained from computational fluid dynamics (CFD) simulations to assess the ventilations and pollutant dispersion within street canyons with a parallel approaching wind. The results show that the street morphology characteristics, including the street width, lateral openings and intersections, are closely related to the air flows in street canyons. The air quality improves with a decreasing aspect ratio of central street owing to a larger vertical exchange through the street roof, which suggests an open central street is of better air quality. The lateral openings and intersections of streets have important effects on the air flows in street canyons, and the effects are particularly pronounced when the street widths are similar. The street continuity ratio indicates street continuity. It relates to the openings and the symmetry of a street and impacts on the air flows and pollutant dispersion through the lateral openings of the central street. The street spatial closure ratio is determined by the street continuity ratio and the aspect ratio of the central street. When the aspect ratio of central street is not excessively high, higher values of street continuity ratio and spatial closure ratio

    Post-seismic investigations repeatedly indicate that structures having frequencies close to foundation soil frequencies exhibit significantly heavier damages (Caracas 1967; Mexico 1985; Pujili, Ecuador 1996; L'Aquila 2009). However, observations of modal frequencies of soils and buildings in a region or within a current seismic risk analysis are not fully considered together, even when past earthquakes have demonstrated that coinciding soil and building frequencies leads to greater damage. The present paper thus focuses on a comprehensive numerical analysis to investigate the effect of coincidence between site and building frequencies. A total of 887 realistic soil profiles are coupled with a set of 141 single-degree-of-freedom elastoplastic oscillators, and their combined (nonlinear) response is computed for both linear and nonlinear soil behaviors, for a large number (60) of synthetic input signals with various PGA levels and frequency contents. The associated damage is quantified on the basis of the maximum displacement as compared to both yield and ultimate post-elastic displacements, according to the RISK-UE project recommendations (Lagomarsino and Giovinazzi in Bull Earthq Eng 4(4):415-443, 2006), and compared with the damage obtained in the case of a similar building located on rock. The correlation between this soil/rock damage increment and a number of simplified mechanical and loading parameters is then analyzed using a neural network approach. The results emphasize the key role played by the building/soil frequency ratio even when both soil and building behave nonlinearly; other important parameters are the PGA level, the soil/rock velocity contrast and the building ductility. A numerical investigation based on simulation of ambient noise for the whole set of 887 profiles also indicates that the amplitude of H/ V ratio may be considered as a satisfactory proxy for site amplification when applied to measurements at urban scale.

    This study investigated the ;roadside-to-ambient; evolution of particle physicochemical and optical properties in typical urban atmospheres of Hong Kong through collection of chemically-resolved PM2.5 data and PM2.5 size distribution at a roadside and an ambient site. Roadside particle size distribution showed typical peaks in the nuclei mode (30-40 nm) while ambient measurements peaked in the Aitken mode (50-70 nm), revealing possible condensation and coagulation growth of freshly emitted particles during aging processes. Much higher levels of anthropogenic chemical components, i.e. nitrate, sulfate, ammonium, organic carbon (OC) and elemental carbon (EC), but lower levels of OC/EC and secondary inorganic aerosols (SIA)/EC ratios appeared in roadside than ambient particles. The high OC/EC and SIA/EC ratios in ambient particles implied high contributions from secondary aerosols. Black carbon (BC), a strong light absorbing material, showed large variations in optical properties when mixed with other inorganic and organic components. Particle-bound polycyclic aromatic hydrocarbons (p-PAHs), an indicator of brown carbon (BrC), showed significant UV-absorbing ability. The average BC and p-PAHs concentrations were 3.8 and 87.6 ng m-3, respectively, at the roadside, but were only 1.5 and 18.1 ng m-3 at the ambient site, suggesting BC and p-PAHs concentrations heavily driven by traffic emissions. In contrast, PM2.5 UV light absorption coefficients (babs-BrC,370nm) at the ambient site (4.2 Mm-1) and at the roadside site (4.1 Mm-1) were similar, emphasizing that particle aging processes enhanced UV light-absorbing properties, a conclusion that was also supported by the finding that the Absorption Ångström coefficient (AAC) value at UV wavelengths (AAC_UV band) at the ambient site were ∼1.7 times higher than that at the roadside. Both aqueous reaction and photochemically produced secondary organic aerosol (SOA) for ambient aerosols contributed to the peak values of babs

    Atmosphere and Ambient Space This paper explores the relation between atmosphere and ambient space. Atmosphere and ambient space share many salient properties. They are both ontologically indeterminate, constantly varying and formally diffuse and they are both experienced as a subtle, non......-signifying property of a given space. But from a certain point of view, the two concepts also designate quite dissimilar experiences of space. To be ’ambient’ means to surround. Accordingly, ambient space is that space, which surrounds something or somebody. (Gibson 1987: 65) Since space is essentially...... of a surrounding character, all space can thus be described as having a fundamentally ambient character. So what precisely is an ambient space, then? As I will argue in my presentation, ambient space is a sensory effect of spatiality when a space is experienced as being particularly surrounding: a ‘space effect...

    Full Text Available Ambient art is the aesthetic presentation of information, using artistic techniques to achieve a pleasing image that also contains hidden depths, where exposure to it over time allows a viewer to understand something about the information sources that it represents. This paper reviews the artistic and computational background of ambient systems, and presents two case studies of systems developed by our research team, from their initial design to the experiences of the people encountering them. The first case presents a photo mosaic of images based on the news headlines coupled with a structured picture based on the weather; the second presents stylistic perspectives on activity in a public space. Both are evaluated and demonstrate that different forms of aesthetically pleasing displays can convey information to viewers.

    The research field of ambient media starts to spread rapidly and first applications for consumer homes are on the way. Ambient media is the logical continuation of research around media. Media has been evolving from old media (e.g. print media), to integrated presentation in one form (multimedia - or new media), to generating a synthetic world (virtual reality), to the natural environment is the user-interface (ambient media), and will be evolving towards real/synthetic undistinguishable media (bio-media or bio-multimedia). After the IT bubble was bursting, multimedia was lacking a vision of potential future scenarios and applications. Within this research paper the potentials, applications, and market available solutions of mobile ambient multimedia are studied. The different features of ambient mobile multimedia are manifold and include wearable computers, adaptive software, context awareness, ubiquitous computers, middleware, and wireless networks.

    gobernabilidad de las relaciones, no existe formalización de los elementos relacionales, lo que puede crear problemas relativos al uso del oportunismo por parte de los contratados. El último aspecto remite a los mecanismos isomorfos, una vez que contratos distintos entre las mismas organizaciones son vistos por las partes como únicos, por estar sujetos a las mismas condiciones y presiones y por tener gestiones similares.O objetivo da presente pesquisa é analisar relacionamentos entre contratante e contratados em ambientes que utilizam contratos estruturados, mais especificamente o emprego desses  contratos para tratar dos aspectos relacionais desses relacionamentos. Assim, o foco principal da presente pesquisa são os relacionamentos entre uma grande multinacional e  seus fornecedores de produtos e serviços. Como estratégia de pesquisa, realizou-se, primeiramente, um levantamento de 94 contratos estabelecidos pela contratante. A partir desse levantamento, tendo como referência seis parâmetros identificados na revisão daliteratura, realizou-se a escolha dos cinco casos (contratos a serem estudados. Esses mesmos parâmetros foram  utilizados para a definição do roteiro de entrevista. Uma vez definidos os casos, foram selecionados onze gestores (sujeitos da pesquisa da contratante e dos contratados, para a realização das entrevistas. Como conclusão, observa-se que em contratos com fornecimento de pouca tecnologia existe maior dependência da contratada, mas essa dependência diminui à medida que se incorpora mais tecnologia no fornecimento de produtos e serviços. Quanto à governança relacional, não existe formalização dos elementos relacionais, o que pode criar problemas relativos ao uso do oportunismo por parte dos contratados. O último aspecto remete aos mecanismos isomórficos, uma vez que contratos distintos entre as mesmas organizações são vistos pelas partes como únicos, por estarem sujeitos às mesmas condições e pressões e

The presentations describes the objectives of the project, the steps taken and the results obtained during the feasibility study. The project aims to develop an environmental health information system that will allow the monitoring of public health and its health determinants and make international comparisons, develop environmental policies and facilitate communication with citizens. WHO developed a methodology for the development of these indicators within the conceptual framework of DPSEEA (Driving Force, Pressure, State, Exposure, Effect, Action and selected a total of 55 indicators (which included 168 variables in 10 environmental health areas. The feasibility study predicted the successful gathering of 89% of the indicators. However, data recollection proved difficult due to the frequent incompatibility of some variables in the Spanish information systems with the WHO defined variables. On a management level, the greatest difficulty arose from the disperse distribution of responsibilities in environmental health matters. In addition to the technical contribution of this project to Environmental Health in Spain, an added value has been to establish a close collaboration with the different Ministries involved.Esta ponencia presenta una visión general del proyecto de Indicadores de Salud Ambiental, coordinado por la OMS a nivel internacional y liderado por el Centro de Investigación sobre el Síndrome del Aceite Tóxico y Enfermedades Raras (CISATER en España.

    Full Text Available A sustentabilidade está apoiada principalmente nas dimensões econômica, ambiental e social. No entanto, sem a dimensão política ela não se constrói. Um dos principais instrumentos de comando e controle da política nacional de meio ambiente, o licenciamento ambiental é um processo contínuo de gestão ambiental pública e privada. Analisou-se o processo de licenciamento ambiental como acoplamento estrutural entre os sistemas social, econômico e ambiental. Apesar da constatação de críticas aos mecanismos de comando e controle dos últimos anos, foi verificado que o Estado do Rio de Janeiro tem buscado integrar a política ambiental do Estado à gestão ambiental privada e que esta integração busca atender às demandas dos sistemas sociais e econômicos para as questões ambientais. Em linhas gerais, este caminho segue as estratégias e ações propostas na Agenda 21 brasileira.

Dans ce contexte, cet article s’intéresse à l’émergence et à la mise en œuvre d’une politique publique touchant la Gestion LOcale SÉcurisée (GELOSE dont le principal objectif vise à transférer la gestion de ces ressources, de l’État vers les communautés locales, dans le but de les protéger plus efficacement. Cette lecture montre cependant que les objectifs, les ressources et les stratégies des principaux acteurs concernés sont difficilement conciliables et que le système de relation qu’il induit n’est pas nécessairement en phase avec les finalités poursuivies.Marked by exceptional biodiversity and extreme human poverty, Madagascar is experiencing a rapid destruction of its natural resources, placing territory and its appropriation at the heart of development issues. From this perspective, this article will look at the development and implementation of a public policy, the Gestion LOcale SÉcurisée (GELOSE, for the local management of natural renewable resources. This regulation seeks to transfer the management of these resources from the government to local communities in the goal of protecting them more effectively. We will see, however, that the objectives, resources and strategies of the primary actors concerned are difficult to reconcile at best and that the relational system to which the policy gives rise is not necessarily in keeping with the goals being pursued.

    To evaluate the potential economic benefits of keeping a meningitis A vaccine at or near ambient temperature for up to 4 days during a mass vaccination campaign. During a 10-day mass vaccination campaign against meningitis A in three regions of Chad in 2011, the costs associated with storage and transport of the vaccine in a traditional cold chain system were evaluated. A mathematical model was used to estimate the savings that could have been achieved if the vaccine had been stored at or near ambient temperature--in a "controlled temperature" chain--at the peripheral levels of the supply chain system. The cost of the cold chain and associated logistics used in the campaign in Chad was 0.24 United States dollars (US$) per person vaccinated. In the modelled scenario for a controlled temperature chain, however, these costs dropped by 50% and were estimated to be only US$ 0.12 per person vaccinated. The implementation of a "controlled temperature" chain at the most peripheral levels of the supply chain system--assuming no associated loss of vaccine potency, efficacy or safety--could result in major economic benefits and allow vaccine coverage to be extended in low-resource settings.

    Ambient air pollution has been associated with respiratory diseases in children. However, its effects on pediatric pneumonia have not been meta-analyzed. We conducted a systematic review and meta-analysis of the short-term association between ambient air pollution and hospitalization of children due to pneumonia. We searched the Web of Science and PubMed for indexed publications up to January 2017. Pollutant-specific excess risk percentage (ER%) and confidence intervals (CI) were estimated using random effect models for particulate matter (PM) with diameter ≤ 10 (PM 10 ) and ≤2.5 μm (PM 2.5 ), sulfur dioxide (SO 2 ), ozone (O 3 ), nitrogen dioxide (NO 2 ), and carbon monoxide (CO). Results were further stratified by subgroups (children under five, emergency visits versus hospital admissions, income level of study location, and exposure period). Seventeen studies were included in the meta-analysis. The ER% per 10 μg/m 3 increase of pollutants was 1.5% (95% CI: 0.6%-2.4%) for PM 10 and 1.8% (95% CI: 0.5%-3.1%) for PM 2.5 . The corresponding values per 10 ppb increment of gaseous pollutants were 2.9% (95% CI: 0.4%-5.3%) for SO 2 , 1.7% (95% CI: 0.5%-2.8%) for O 3 , and 1.4% (95% CI: 0.4%-2.4%) for NO 2 . ER% per 1000 ppb increment of CO was 0.9% (95% CI: 0.0%-1.9%). Associations were not substantially different between subgroups. This meta-analysis shows a positive association between daily levels of ambient air pollution markers and hospitalization of children due to pneumonia. However, lack of studies from low-and middle-income countries limits the quantitative generalizability given that susceptibilities to the adverse effects of air pollution may be different in those populations. The meta-regression in our analysis further demonstrated a strong effect of country income level on heterogeneity. Copyright © 2017 Elsevier Ltd. All rights reserved.

  5. Can we use the q-Gaussian of ambient noise fluctuations as a vulnerability index? A case study in Cultural Heritage buildings

    In this work we study in terms of Tsallis statistical mechanics the properties of microtremors' fluctuations in two church bell towers, which are monuments of cultural heritage, in the city of Chania (Crete, Greece). We have shown that fluctuations of ambient vibrations recordings in the Church tower bells follow a q-Gaussian distribution. The behavior of Tsallis q parameter with the level (high) of the measuring point within the tower and the amplification factors at that points as extracted from horizontal-to-vertical (HVSR) spectral ratios are presented and discussed. Since q decreases as the amplification factor increases, we could suggest q as a vulnerability index, where, as q decreases approaching unity, then the structural system is getting more vulnerable. The latter approach suggests that introducing ideas of Tsallis statistics could be useful in characterizing extremely complex processes as that governed the estimation of seismic vulnerability in which a multidisciplinary approach is required.

  6. Site responses based on ambient vibrations and earthquake data: a case study from the meizoseismal area of the 2001 Bhuj earthquake

    The 2001 Mw 7.6 earthquake sourced in the Kachchh rift of northwest India led to extensive damage in the city of Bhuj, located 70 km southwest of its epicenter. The building stock of this densely populated city was a mix of modern, single, and multistoried structures as well as traditional and non-engineered abodes, most of which were not designed to withstand severe shaking effects. Although there was extensive liquefaction and ground failure in the meizoseismal area, they were not observed in Bhuj, but the damage was severe here. In this study, we apply horizontal to vertical spectral ratio method to ambient vibrations (HVSR-AV) to obtain fundamental resonance frequency (f0) and H/V peak amplitude (A0) to examine if site response had any significant role in the observed damage. The patterns of H/V curves as well as spatial distributions of f0 (0.6-1.4 Hz) and A0 (1.5-4.4) suggest absence of any strong impedance contrast within the subsurface. Similar results obtained for ambient vibrations and earthquake signals suggest the efficacy of the HVSR-AV method as most useful for regions of low-level seismicity. The weathered sandstone that is generally exposed in the city represents the resonating layer whose thickness is approximately estimated as 66-155 m, based on 1D assumption. The current set of available data precludes any quantitative modeling, but our preliminary inference is that site effects were not significant during the 2001 earthquake damage observed in Bhuj.

    Hygroscopic growth occurs when particles take up water vapor and grow when exposed to elevated relative humidity (RH), and is controlled largely by chemical composition. Previous laboratory studies of biomass burning and combustion particles observed particle size shrinkage as soot aerosols, especially those with coatings, were exposed to increasing RH levels, which resulted in sub-1.0 hygroscopicity parameter values (i.e., ratio of humidified-to-dry diameter g(RH) and ratio of humidified-to-dry scattering coefficients f(RH)). To investigate the potential for sub-1.0 hygroscopicity in ambient aerosol, we utilized data from (i) a ship-board HTDMA during E-PEACE 2011, (ii) multiple instruments on the DC8 during SEAC4RS-2013, as well as (iii) the DASH-SP during measurement intensives in Summer 2014 and Winter 2015 in Tucson, Arizona. Suppressed hygroscopicity, including sub-1.0 g(RH), was observed during smoke-influenced periods in SEAC4RS, episodic events in the winter season in Arizona, and smoke-influenced air during E-PEACE. Across the range of RH investigated (75-95%), sub-1.0 g(RH) was lowest at the highest RH values probed (~95%). These sub-1.0 g(RH) observations are consistent with elevated black carbon and organic aerosol concentration in both E-PEACE and SEAC4RS. Collocated measurements during SEAC4RS indicate elevated spikes in black carbon concentrations are coincident with both sub-1.0 f(RH) and g(RH) observations, as well as elevated organic aerosol- and gas-phase fire tracers such as AMS f60 and PTR-MS acetonitrile concentration. This is the first set of ambient observations of sub-1.0 hygroscopicity factors g(RH) and f(RH), with consistency across different instruments, regions, and platforms. Although particle restructuring has been demonstrated in laboratory experiments, field observations are complex as soot coating, secondary chemistry, and heterogeneous processing can occur on the same time scale as measurements.

    PM2.5 has gradually become a major environmental problem of China with its rapid economic development, urbanization, and increasing of motor vehicles. Findings and awareness of serious PM2.5 pollution make the PM2.5 a new criterion pollutant of the Chinese National Ambient Air Quality Standard (NAAQS) revised in 2012. The 2012 NAAQS sets the PM2.5 concentrate limitation with the 24-hour average value and the annual mean value. Wuhan is quite typical among central and southern China in climate, economy, development level, and energy consumption. The data are cited from the official website of Wuhan Environmental Protection Bureau and cover the period from 1 January to 30 June 2013. The data definitely confirm the existence of serious PM2.5 pollution in Wuhan and indicate that the addition of PM2.5 as a criterion pollutant significantly brings down the attainment rate of air quality. The example of Wuhan reveals that local governments should take measures to reduce the emission of PM2.5 if it affects the attainment rate and the performance evaluation value of air quality. The main contribution of 2012 NAAQS is that it brings down the attainment rate of the air quality and forces local governmental officials to take the measures accordingly.

    Full Text Available Oxygen serves as an essential factor for oxidative stress, and it has been shown to be a mutagen in bacteria. While it is well established that ambient oxygen can also cause genomic instability in cultured mammalian cells, its effect on de novo tumorigenesis at the organismal level is unclear. Herein, by decreasing ambient oxygen exposure, we report a ∼50% increase in the median tumor-free survival time of p53-/- mice. In the thymus, reducing oxygen exposure decreased the levels of oxidative DNA damage and RAG recombinase, both of which are known to promote lymphomagenesis in p53-/- mice. Oxygen is further shown to be associated with genomic instability in two additional cancer models involving the APC tumor suppressor gene and chemical carcinogenesis. Together, these observations represent the first report directly testing the effect of ambient oxygen on de novo tumorigenesis and provide important physiologic evidence demonstrating its critical role in increasing genomic instability in vivo.

    Alzheimer's disease (AD) is one of the most disabling diseases to affect large numbers of elderly people worldwide. Because of the characteristics of this disease, patients with AD require daily assistance from service providers both in nursing homes and at home. Domiciliary assistance has been demonstrated to be cost effective and efficient in the first phase of the disease, helping to slow down the course of the illness, improve the quality of life and care, and extend independence for patients and caregivers. In this context, the aim of this work is to demonstrate the technical effectiveness and acceptability of an innovative domiciliary smart sensor system for providing domiciliary assistance to patients with AD which has been developed with an Ambient Assisted Living (AAL) approach. The design, development, testing, and evaluation of the innovative technological solution were performed by a multidisciplinary team. In all, 15 sociomedical operators and 14 patients with AD were directly involved in defining the end-users' needs and requirements, identifying design principles with acceptability and usability features and evaluating the technological solutions before and after the real experimentation. A modular technological system was produced to help caregivers continuously monitor the health status, safety, and daily activities of patients with AD. During the experimentation, the acceptability, utility, usability, and efficacy of this system were evaluated as quite positive. The experience described in this article demonstrated that AAL technologies are feasible and effective nowadays and can be actively used in assisting patients with AD in their homes. The extensive involvement of caregivers in the experimentation allowed to assess that there is, through the use of the technological system, a proven improvement in care performance and efficiency of care provision by both formal and informal caregivers and consequently an increase in the quality of life of

  4. The Effect of Seasonal Ambient Temperatures on Fire-Stimulated Germination of Species with Physiological Dormancy: A Case Study Using Boronia (Rutaceae)

    Dormancy and germination requirements determine the timing and magnitude of seedling emergence, with important consequences for seedling survival and growth. Physiological dormancy is the most widespread form of dormancy in flowering plants, yet the seed ecology of species with this dormancy type is poorly understood in fire-prone vegetation. The role of seasonal temperatures as germination cues in these habitats is often overlooked due to a focus on direct fire cues such as heat shock and smoke, and little is known about the combined effects of multiple fire-related cues and environmental cues as these are seldom assessed in combination. We aimed to improve understanding of the germination requirements of species with physiological dormancy in fire-prone floras by investigating germination responses across members of the Rutaceae from south eastern Australia. We used a fully factorial experimental design to quantify the individual and combined effects of heat shock, smoke and seasonal ambient temperatures on germination of freshly dispersed seeds of seven species of Boronia, a large and difficult-to-germinate genus. Germination syndromes were highly variable but correlated with broad patterns in seed morphology and phylogenetic relationships between species. Seasonal temperatures influenced the rate and/or magnitude of germination responses in six species, and interacted with fire cues in complex ways. The combined effects of heat shock and smoke ranged from neutral to additive, synergistic, unitive or negative and varied with species, seasonal temperatures and duration of incubation. These responses could not be reliably predicted from the effect of the application of single cues. Based on these findings, fire season and fire intensity are predicted to affect both the magnitude and timing of seedling emergence in wild populations of species with physiological dormancy, with important implications for current fire management practices and for population

    2004-02-01

    Emissions data are often lacking or uncertain for many airborne contaminants. Chemicals, such as polycyclic aromatic hydrocarbons (PAHs), emitted from combustion sources, fall into this category. Currently available ambient-air emission inventories of PAHs either fail to account for population-based activities (such as residential wood combustion and motor vehicle activity) and/or report ''total PAH'' or particulate organic matter emissions instead of individual compounds. We measure the degree of overlap between predicted concentrations from estimated emissions with measured concentrations. Our analysis is, based on probabilistic analysis of measured outdoor air concentrations with those predicted from mass-balance models. Based on available information, we estimate the relative magnitude of emissions from four major sources of PAHs to outdoor air- (1) on-road motor vehicles, including light-duty gasoline vehicles and diesel-powered buses and medium and heavy duty trucks; (2) residential wood combustion; and (3) power generation from external combustion boilers. We use the CalTOX regional multimedia mass-balance model to evaluate our emissions estimates in rural and urban regions of the state of Minnesota, USA. We compare model estimates of outdoor PAH airborne concentrations with those reported by the Minnesota Children's Pesticide Exposure Study (MNCPES). With these measured concentrations we probabilistically evaluate our emissions and interpret the reliability of our emissions estimates for specific PAHs. The median estimates of our predicted outdoor air concentrations agree within an order of magnitude of measured concentrations. For four representative PAHs, we were able to obtain a reasonable degree of overlap between empirical and predicted distributions of outdoor air concentrations. Our combination of models, emissions estimates, and empirical concentration data estimate exposure in a manner that is more reliable than any of

In recent times, due to population growth, urban sprawl, industrial development, and vehicular boom, the quality of air is deteriorating and being polluted. Pollutants of major public health concerns include particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulfur dioxide, which pose serious threats to human health and hygiene. In the present study, prime particulate pollutants (PM10, PM2.5, and gaseous pollutants (SO2, and NO2 were estimated at seven stations in and around Dahej Port, Gujarat, India. The obtained values of PM10, PM2.5, SO2, and NO2 in all the studied stations (seven ranged from 67.39 to 98.75, 29.57 to 45.79, 17.76 to 22.29 and 28.29 to 32.42 mg/m3, respectively. The level of PM10 at all sampling locations, and that of PM2.5 at Station A3 (Lakhigam were found little higher than prescribed permissible limits of CPCB standards, while SO2 and NO2levels were within the acceptable range. The Air Quality Index (AQI score was found to be ranged from 76.50 to 97.75, which is at satisfactory level as per CPCB standards. Further, precautionary measures and management strategies to minimize the effect of particulate as well as gaseous pollutants have also been suggested for achieving its ambient levels in and around Dahej Port, Gujarat, India.International Journal of EnvironmentVolume-6, Issue-4, Sep-Nov 2017, page: 28-41

    Obiettivo: sviluppare un modello di gestione informatizzata delle liste di attesa, specificamente per l’assistenza ospedaliera in regime di ricovero ordinario e diurno. Questo consentirà di tastare in tempo reale il “polso” della situazione, garantendo peraltro quanto previsto dalle disposizioni legislative in materia, anche attraverso un controllo diretto della Direzione Medica di Presidio, che garantisca la complessiva gestione del registro secondo criteri di eticità e trasparenza.

    Metodi: creare un database per le liste di attesa, condivisibile nell’ambito della rete ospedaliera e accessibile tramite password, contenente i seguenti record:

     • Codice identificativo U.O.C.

     • Codice Identificativo Procedura

    • Generalità paziente

     • Data visita

     • Codice di Criticità (descrive l’urgenza del ricovero

     • Medico che ha effettuato la visita

     • Data del ricovero

     • Note Conclusioni: la partecipazione, a vari livelli di responsabilità e di operatività, di varie figure professionali, è l’elemento fondante di un percorso legato alla definizione di procedure chiare, attuabili e condivise da tutti gli attori del processo.

    L’informatizzazione del sistema potrebbe permettere una visualizzazione in tempo reale per ciascuna U.O.C. delle liste di attesa, classificando i casi secondo un criterio di urgenza del ricovero. Allo stesso tempo la Direzione Medica avrebbe costantemente sotto controllo le liste di attesa, vigilando sull’osservanza degli obblighi di trasparenza ed eticità sanciti dalle disposizioni legislative. L’accesso ai dati limitato al solo personale medico, ottenuto attraverso la gestione informatica protetta, garantirebbe infine il rispetto della privacy.

    Full Text Available Face aux évolutions du secteur bancaire (concurrence accrue, crise de confiance l’adoption d’un système de gestion de la relation client représente un enjeu important pour les banques. Il contribue à l’optimisation de la gestion du portefeuille client, plus précisément ce système permet d’acquérir de nouveaux clients et d’augmenter la rentabilité des clients existants. Cet article a pour objectif de répondre à la problématique suivante: le système de gestion de la relation client permet-il aux banques d’atteindre les objectifs attendus? L’étude que nous avons réalisée auprès de 47 banques commerciales marocaines montre que malgré le potentiel anticipé, les bénéfices escomptés d’un tel système restent limités. En effet, l’utilisation de ce système reste à son état embryonnaire, il se centre principalement sur la collecte des informations clients au niveau des agences tandis que l’analyse et l’exploitation de ces informations se fait au niveau du siège de la banque. De même, les opérations basiques de la banque occupent une grande part du temps de travail des agents de la banque au dépend des services bancaires à valeur ajoutée. D’un autre côté, une grande part des banques adoptant ce système ne mesurent pas le coût de la relation avec leurs clients.

  10. La gestione dei flussi turistici tramite sistemi di trasporto innovativi: l’esempio di Perugia

    2010-10-01

    Full Text Available La città di Perugia ha, fin dagli anni ’70, unito alla sua capacità di attrazione turistica, dovuta al patrimonio storico ambientale plurimillenario, una volontà di affrontare il tema della mobilità urbana in maniera profondamente innovativa ed ambientalmente sostenibile. Il concetto della creazione di parcheggi di attestazione, serviti da percorsi meccanizzati di risalita verso l’acropoli, è stato recentemente ampliato dalla creazione del Minimetro, mezzo di trasporto innovativo, dal ridottissimo impatto ambientale, che unisce in soli 12 minuti, con un servizio semicontinuo, l’area di valle di Pian di Massiano, dotata di un capace parcheggio da circa 2800 posti auto, al centro cittadino, servendo diversi quartieri urbani. Tale sistema di trasporto, corridoio forte del trasporto pubblico urbano, ha fornito lo spunto per attuare una nuova modalità di gestione dei flussi turistici, che individua nel Minimetro la modalità principale di accesso al centro storico sia per i gruppi a numero ridotto, sia per i gruppi organizzati in arrivo con i bus turistici. L’organizzazione della mobilità turistica che ne è derivata costituisce un ulteriore passo in avanti lungo quell’itinerario di gestione della città che cerca di coniugare l’attrattiva turistica, con le sue ricadute in termini di crescita economica, e la salvaguardia del patrimonio storico artistico e della qualità della vita dei cittadini. Gli scenari futuri vedono un’iniezione di tecnologia in questo contesto, con l’introduzione nella gestione dei flussi turistici dei concetti di accreditamento, dell’infomobilità come supporto alle politiche urbane, del controllo unito alla fornitura di servizi georeferenziati.

    2008-04-01

    Increasingly, cars are fitted with interior ambient lighting which is switched on while driving. This special kind of interior light emphasizes the interior design of the car, it makes a car look special and gives the buyers a new option to personalize their automobiles. But how does ambient interior light influence the driver? We conducted a series of over 50 tests to study the influence of interior ambient light on contrast perception under different illumination levels, colors and positions of the illuminated areas. Our tests show that in many cases the ambient lighting can improve the visual contrast for seeing objects in the headlamp beam. But the test persons mentioned that the tested brightness looked too bright and that they felt glared. The measured values instead proved that no disability glare exists. Therefore, provided that the drivers can adjust the intensity of the ambient light to avoid glare, the ambient light has no negative effect on the drivers' contrast perception.

  20. Analysis of coupled model uncertainties in source-to-dose modeling of human exposures to ambient air pollution: A PM 2.5 case study

    Science.gov (United States)

    Özkaynak, Halûk; Frey, H. Christopher; Burke, Janet; Pinder, Robert W.

    Quantitative assessment of human exposures and health effects due to air pollution involve detailed characterization of impacts of air quality on exposure and dose. A key challenge is to integrate these three components on a consistent spatial and temporal basis taking into account linkages and feedbacks. The current state-of-practice for such assessments is to exercise emission, meteorology, air quality, exposure, and dose models separately, and to link them together by using the output of one model as input to the subsequent downstream model. Quantification of variability and uncertainty has been an important topic in the exposure assessment community for a number of years. Variability refers to differences in the value of a quantity (e.g., exposure) over time, space, or among individuals. Uncertainty refers to lack of knowledge regarding the true value of a quantity. An emerging challenge is how to quantify variability and uncertainty in integrated assessments over the source-to-dose continuum by considering contributions from individual as well as linked components. For a case study of fine particulate matter (PM 2.5) in North Carolina during July 2002, we characterize variability and uncertainty associated with each of the individual concentration, exposure and dose models that are linked, and use a conceptual framework to quantify and evaluate the implications of coupled model uncertainties. We find that the resulting overall uncertainties due to combined effects of both variability and uncertainty are smaller (usually by a factor of 3-4) than the crudely multiplied model-specific overall uncertainty ratios. Future research will need to examine the impact of potential dependencies among the model components by conducting a truly coupled modeling analysis.

    Full Text Available Dans la mouvance des grandes mutations des années 1960-1970 en Camargue gardoise et face à l’obsolescence du Traité des Marais qui réglait la gestion collective des niveaux d’eau, les acteurs économiques liés à l’eau se sont positionnés sur des logiques individualistes. L’eau est devenue l’objet de maints conflits avec de graves conséquences sur les ressources et les milieux. La mise en œuvre d’une Charte de l’environnement et d’un SAGE au début des années 1990 a constitué les prémices du retour du « collectif » dans la gestion de l’eau. Mais on est encore loin de l’eau comme vecteur d’une construction territoriale à travers une communauté de projets liée à l’eau. Dans ce contexte, les crues de 2002 et 2003 sont apparues comme des révélateurs des inadéquations territoriales en cas de gestion de crise. Elles montrent que les politiques de l’eau ne peuvent faire l’impasse d’une réflexion sur l’articulation entre les différents espaces de décision et de solidarité.Next to the major changes which occurred in the « Camargue gardoise » during sixties and seventies, and because of the becoming obsolete « Traité des Marais » which was regulating the collective management of water levels, the economic actors dealing with water concerns have been developing individualistic policies. Water has became a source of many conflicts implying serious consequences on resources and natural spaces. The achievement of an environmental chart and of a « SAGE » at the beginning of the nineties were the ground baits for a come back to a collective form of water management. However, it’s a long way to consider water as a vector of territorial construction thanks to collective agreements about projects dealing with water. In the following context, the 2002 and 2003 floods have revealed territorial limitations to manage this kind of crisis. They have shown that the water policies have to take inot

    Full Text Available A new interdisciplinary field that combines science, engineering knowledge management and practice has been incorporated into business models and is called Management of Technology (MOT (Mezher, Nasrallahand Allemedine, 2006. Technology is defined as all the knowledge, products, processes, tools, methods and systems used to create goods and provide services. In general speaking the technology is the way we do things and MOT is the key to competitiveness and wealth creation (Khalil, 2000. The elements that make up the various models are key to success in results, so in this article we present different models and its main elements to identify what are those key elements, including innovation. As Peter Drucker said (Drejer, 2002, p.6 the concept “innovation" means both a process and its outcome. Following the definition given by the European Commission on "The Green Book on Innovation (European Commission, 1995, innovation is the transformation of an idea into a marketable product or service new or improved, a process for manufacturing or distribution operating, new or improved, or a new method of providing a social service. It is therefore a definition linked to the first of the meanings, the innovation as a process. However, when the concept innovation refers to the product, equipment, process or service improvements on the market, the emphasis is placed on the outcome of the process. In this case, innovation is considered as such when introduced into the market (product innovation or used in the process of producing goods or providing services (process innovation.

    2010-02-01

    Full Text Available The BioAmbients calculus is a process algebra suitable for representing compartmentalization, molecular localization and movements between compartments. In this paper we enrich this calculus with a static type system classifying each ambient with group types specifying the kind of compartments in which the ambient can stay. The type system ensures that, in a well-typed process, ambients cannot be nested in a way that violates the type hierarchy. Exploiting the information given by the group types, we also extend the operational semantics of BioAmbients with rules signalling errors that may derive from undesired ambients' moves (i.e. merging incompatible tissues. Thus, the signal of errors can help the modeller to detect and locate unwanted situations that may arise in a biological system, and give practical hints on how to avoid the undesired behaviour.

    Full Text Available Cet article propose une analyse de la financiarisation de la gestion à partir de l’étude du cas de la principale institution financière publique au Canada, la Caisse de Dépôt et Placement du Québec. Cette évolution de la gestion est documentée ici à travers deux éléments. Le premier élément est le modèle d'affaire mis de l'avant par l'institution avec l'arrivée d'un nouveau PDG en 2002 qui repose sur une nouvelle interprétation du mandat de l'institution et de sa responsabilité sociétale. Le second élément est la réforme de l'organisation interne de la Caisse avec l'adoption d'un modèle organisationnel de conglomérat financier basé sur l'utilisation indirecte des produits dérivés ou indirect à travers des produits structurés. Cette étude de cas permet également d’analyser les transformations récentes des modes de gouvernance dans les institutions financières.This article proposes an analysis of the financialization of public pension’s asset managers through the case study of the most important one in Canada. The 2008 fallout is the result of structural changes in the regulation and management of the organization. Two elements are here at the core of financialization. First, the new business model was built on a different analysis of the mission of the institution. Second, the creation of "value added" was expected by the use of interactions between portfolios, facilitated by the development of derivatives and structured financial products. This case study is also interesting to analyze the transformation of the governance structure in the financial sector.

    1990-12-01

    Full Text Available Les relations que les agriculteurs d’un village lorrain entretiennent avec leur territoire sont dynamiques. En un siècle, la répartition des cultures est devenue concentrique, centrée sur le bâti villageois, et la «sortie» des bâtiments agricoles de leur «gangue» villageoise a été un facteur décisif de cette dynamique. Les conséquences de cette actuelle gestion territoriale de l’activité agricole sont multiples et concernent le fonctionnement interne aux exploitations du village, les transferts de fertilité, donc les risques de pollution des eaux souterraines, et la création d’un paysage.

    Easy ambient sonic spray ionization (EASI) and desorption electrospray ionization (DESI) were used for imaging of a number of samples, including sections of rat brain and imprints of plant material on porous Teflon. A novel approach termed Displaced Dual-mode Imaging was utilized for the direct...... comparison of the two methods: Images were recorded with the individual rows alternating between EASI and DESI, yielding a separate image for each technique recorded under perfectly similar conditions on the same sample. EASI works reliably for imaging of all samples, but the choice of spray solvent and flow...... rate is more critical in tissue imaging with EASI than with DESI. The overall sensitivity of EASI is, in general, slightly lower than that of DESI, and the representation of the dynamic range is different in images of the two techniques for some samples.

    Conrad, Heloise

    L'evolution technologique des composants electroniques entraine des problemes de gestion de l'obsolescence dans le secteur aeronautique. Les systemes aeronautiques ont en effet des durees de vie nettement superieures aux composants qu'ils contiennent. Cette difference de duree de vie et les normes strictes propres a l'aeronautique obligent les constructeurs a mettre en place une gestion efficace de l'obsolescence pour eviter les couts supplementaires de maintenance et de retards. De plus, a cause des faibles volumes de production qu'ils representent, les constructeurs aeronautiques n'ont que peu de controle sur leur chaine d'approvisionnement. La litterature offre beaucoup d'etudes sur l'obsolescence, appliquees a l'aeronautique. Les auteurs recommandent de mettre en place des processus de gestion et de prevision de l'obsolescence, et de construire des relations de collaboration avec leurs fournisseurs, qui ont plus de visibilite sur la chaine d'approvisionnement. Cette recherche presente d'abord l'elaboration d'une liste de criteres de bonne gestion de l'obsolescence, ainsi que la creation d'une methode de generation de plan de transition et de mise en oeuvre de l'amelioration de la gestion et de la prevision de l'obsolescence pour un cas concret. La methode est creee pour un manufacturier aeronautique ne possedant pas de systemes de gestion proactive ou de prevision de l'obsolescence. La creation de la methode s'est faite en suivant la methodologie de la science de la conception, en impliquant les employes concernes par la gestion de l'obsolescence. La methode comporte douze (12) etapes, amenant au developpement du plan de transition et de mise en oeuvre. Pour applique la methode, divers entretiens individuels et de groupe ont ete realises. Ces entretiens ont aussi permis de lister les criteres de gestion et de prevision efficaces de l'obsolescence. Cette liste a ete comparee avec les criteres issus de la litterature.

  6. Thermal explosion in oscillating ambient conditions

    Science.gov (United States)

    Novozhilov, Vasily

    2016-07-01

    Thermal explosion problem for a medium with oscillating ambient temperature at its boundaries is considered. This is a new problem in thermal explosion theory, not previously considered in a distributed system formulation, but important for combustion and fire science. It describes autoignition of wide range of fires (such as but not limited to piles of biosolids and other organic matter; storages of munitions, explosives, propellants) subjected to temperature variations, such as seasonal or day/night variation. The problem is considered in formulation adopted in classical studies of thermal explosion. Critical conditions are determined by frequency and amplitude of ambient temperature oscillations, as well as by a number of other parameters. Effects of all the parameters on critical conditions are quantified. Results are presented for the case of planar symmetry. Development of thermal explosion in time is also considered, and a new type of unsteady thermal explosion development is discovered where thermal runaway occurs after several periods of temperature oscillations within the medium.

    Full Text Available En France, la gestion de la pêche en eau douce est généralement confiée aux associations de pêcheurs qui agissent sous le contrôle de l’Etat. Le Conseil Supérieur de la Pêche a développé une méthode synthétique d’élaboration de plans de gestion piscicole qui favorisent la reproduction naturelle et le maintien des populations sauvages. Ces plans s’appuient sur des opérations de protection des habitats et de restauration du milieu dont il convient d’évaluer la rentabilité sociale. Ce qui conduit à estimer la valeur du poisson sauvage (c’est à dire né dans le milieu naturel, de parents eux-mêmes sauvages. Cette valeur intègre deux composantes principales, une valeur d’usage qui dérive de la pratique de la pêche et une valeur de non-usage qui découle de son existence même et qui intéresse une population plus vaste que celle des seuls pêcheurs. Les bénéfices potentiels engendrés par la présence de poissons sauvages sont estimés par la méthode d’évaluation contingente. Les résultats empiriques sont basés sur un échantillon de 1 629 pêcheurs qui ont participé à une enquête postale. Le Consentement A Payer (CAP pour le poisson sauvage est une fonction croissante du revenu, de la valeur du matériel et de la distance parcourue pour pêcher. De plus on note que les amateurs de brochets et de truites (espèces repères de l’étude ainsi que ceux qui pêcheraient plus souvent s’il y avait du poisson sauvage ont, toutes choses égales, par ailleurs un CAP plus élevé. La valeur moyenne du CAP varie selon le modèle retenu de 50 F à 100 F par pêcheur et par an. Ce CAP correspond à un concept de valeur totale qui inclut une composante de valeur d’usage et de valeur de non-usage. Certains pêcheurs sont prêts à payer sans pour autant marquer une préférence pour la pêche au poisson sauvage. Leur CAP est associé à une valeur de non-usage et correspond à la valeur d’existence du poisson

Cet article analyse les tendances générales de la participation (notamment au niveau des dispositifs dans les pratiques de gestion des parcs nationaux, qui sont généralement considérées comme des réussites en termes de pratiques politiques ou de gouvernance et qui sont souvent présentées comme des modes d’élaboration de démocratie délibérative. L’analyse utilisant les différents niveaux scalaires tend à montrer au contraire que les dispositifs de participation publique peuvent aussi fragmenter les parties prenantes et rendre plus difficile la constitution efficace d’une coalition d’acteurs.Public involvement has become a key concept in conservation management worldwide.

    Municipal solid waste (MSW) landfill was a main way to disposal of MSW and almost 95% of MSW was disposed by landfills in the world. In order to understand the influence of MSW landfill on polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in surrounding atmosphere, 42 ambient air samples were collected and analyzed from surrounding sites, background site, upwind site and downwind site of a MSW landfill in East China. The results of present study were summarized as follows. (1) The total concentrations of PCDD/Fs (∑PCDD/Fs) in ambient air from surrounding sites, background site, upwind site and downwind site were 2.215±1.004, 2.058±0.458, 2.617±1.092 and 1.822±0.566pgNm -3 , respectively. (2) The toxic equivalent concentrations (TEQ) of PCDD/Fs in ambient air from surrounding sites, background site, upwind site and downwind site were 0.103±0.017, 0.096±0.015, 0.120±0.024 and 0.108±0.014pg I-TEQNm -3 , respectively. (3) The congener profiles, ∑PCDD/Fs and TEQ between background atmosphere and surrounding atmosphere of landfill did not show statistically significant difference. (4) The ∑PCDD/Fs and TEQ in ambient air of downwind site were not higher than that of upwind site, suggesting that studied landfill did not have obvious influence on PCDD/Fs in ambient air from downwind site. (5) The 95th percentile carcinogenic risk (CR) of PCDD/Fs in ambient air from surrounding sites, background site, upwind site and downwind site were 8.03×10 -9 , 7.57×10 -9 , 9.69×10 -9 and 8.15×10 -9 , respectively, which were much lower than the threshold value of CR (10 -6 ), suggesting that studied landfill did not influence the CR of PCDD/Fs in surrounding atmosphere and negligible cancer risk occurred. (6) The non-carcinogenic risk (non-CR) analysis indicated that landfill did not have influence on the non-CR of PCDD/Fs in surrounding atmosphere and no obvious non-carcinogenic effects developed.

    Full Text Available Este artigo apresenta e discute um estudo de caso sobre medição de desempenho ambiental (MDA baseada em um método multicriterial de apoio à decisão, o AHP. A medição foi feita em uma operação de manufatura da indústria automotiva, cujo Sistema de Gestão Ambiental (SGA é certificado conforme a norma ISO 14001:2004. A metodologia foi desenvolvida de forma a viabilizar a sua extensão a outras indústrias ou tipos de operação. O artigo inicia apresentando uma discussão sobre desempenho empresarial e ambiental, justificando a necessidade de um índice para medir e comunicar este desempenho. Cita-se o método multicriterial usado e, a seguir, propõe-se a metodologia de medição, na qual se formulam construtos de sustentação do índice, calculam-se importâncias relativas dos construtos e especificam-se os indicadores. O índice foi calculado para o desempenho atual, chegando-se a um desempenho ambiental próximo a 85% do máximo possível. Os construtos empregados na medição são: resíduos sólidos; efluentes; emissões atmosféricas; uso de recursos naturais; e gestão ambiental. As principais oportunidades de melhoria ambiental são reduções no uso de recursos naturais e em emiss��es atmosféricas.This paper presents and discusses a case concerning environmental performance measurement (MDA, in which a multicriterial approach, the AHP, was used. The measurement took place in a manufacturing operation in the automotive industry, whose environmental management system (SGA is certified according to ISO 14001: 2004. The methodology was developed in such a way that it is feasible to reproduce it in other industries or operations. The paper discusses business and environmental performance, justifying the need for a numerical index, in order to establish such performances. We propose the measurement methodology, in which we formulate hierarchical constructs for sustaining the index, weighed by the AHP and measured by indicators

  10. Ambient cosmology and spacetime singularities

    CERN Document Server

    Antoniadis, Ignatios

    2015-01-01

    We present a new approach to the issues of spacetime singularities and cosmic censorship in general relativity. This is based on the idea that standard 4-dimensional spacetime is the conformal infinity of an ambient metric for the 5-dimensional Einstein equations with fluid sources. We then find that the existence of spacetime singularities in four dimensions is constrained by asymptotic properties of the ambient 5-metric, while the non-degeneracy of the latter crucially depends on cosmic censorship holding on the boundary.

    Full Text Available Le vieillissement de la main-d’œuvre et ses conséquences potentielles préoccupent. Jusqu’à maintenant, les planificateurs ont eu tendance, à l’instar de chercheurs de diverses disciplines, à assimiler cette question à la présence accrue dans les milieux de travail de travailleurs âgés ou de travailleurs vieillissants, des qualificatifs qui sont généralement accolés aux travailleurs dont l’âge d’état civil est 45 ans ou plus. Dans une recherche de nature exploratoire menée dans la fonction publique québécoise, nous avons choisi de suivre une avenue résolument différente et d’examiner comment différents acteurs en co-présence dans les milieux de travail (employés et gestionnaires participent à la construction et à la déconstruction des identités d’âge. L’analyse amène à voir les liens étroits entre ces identités et l’organisation du travail, plus spécifiquement les pratiques de gestion. Les résultats suggèrent, en effet, que les relations qu’entretiennent les employés d’âge différent de même que les caractéristiques attribuées aux uns et aux autres se construisent dans le cours même des pratiques de gestion. La démarche entreprise invite donc à revoir l’a priori d’un « fossé intergénérationnel », déjà existant à l’échelle de la société, et qui ferait du milieu de travail un simple lieu où se manifeste et s’exprime ce fossé.The aging workforce and its potential consequences are causes for concern. To date, planners, like researchers in various disciplines, have tended to merge this issue with the increased presence of older or aging workers - two adjectives that are generally used to describe workers aged 45 or older - in workplaces.

Nel tentativo di razionalizzare l’uso delle risorse naturali e umane, nascono nuovi servizi che fanno intravedere la necessità di creare specifiche figure professionali, in grado di colmare in tempi rapidi il divario tra le potenzialità applicative offerte dalle nuove tecnologie e le diverse realtà operative, ancora legate all’uso di pratiche e metodologie tradizionali. Anche nel settore dei giardini e dei parchi storici è giunto il momento di approfondire i temi relativi alla loro conservazione e valorizzazione, che oggi sono strettamente legati a una concreta sostenibilità economica e ambientale delle pratiche di gestione e di promozione. Queste considerazioni sono state alla base di una serie di iniziative e di progetti promossi a livello nazionale ed europeo, che, grazie all’integrazione di strumenti ICT, SMART-Sensors e IA, in alcuni casi si sono concretizzati nella realizzazione di metodologie e soluzioni di grande interesse operativo.Le procedure e i criteri presentati in questo articolo sono il risultato dell’attività di ricerca e trasferimento tecnologico condotta dal CNR-IBIMET di Firenze negli ultimi dieci anni.

    Ait Hammou, Zouhair

    Cette etude porte sur la conception d'un accumulateur echangeur de chaleur hybride (AECH) pour la gestion simultanee des energies solaire et electrique. Un modele mathematique reposant sur les equations de conservation de la quantite d'energie est expose. Il est developpe pour tester differents materiaux de stockage, entre autres, les materiaux a changement de phase (solide/liquide) et les materiaux de stockage sensible. Un code de calcul est mis en eeuvre sur ordinateur, puis valide a l'aide des resultats analytiques et numeriques de la litterature. En parallele, un prototype experimental a echelle reduite est concu au laboratoire afin de valider le code de calcul. Des simulations sont effectuees pour etudier les effets des parametres de conception et des materiaux de stockage sur le comportement thermique de l'AECH et sur la consommation d'energie electrique. Les resultats des simulations sur quatre mois d'hiver montrent que la paraffine n-octadecane et l'acide caprique sont deux candidats souhaitables pour le stockage d'energie destine au chauffage des habitats. L'utilisation de ces deux materiaux dans l'AECH permet de reduire la consommation d'energie electrique de 32% et d'aplanir le probleme de pointe electrique puisque 90% de l'energie electrique est consommee durant les heures creuses. En plus, en adoptant un tarif preferentiel, le calcul des couts lies a la consommation d'energie electrique montre que le consommateur adoptant ce systeme beneficie d'une reduction de 50% de la facture d'electricite.

    Full Text Available Prenant les déchets électriques et électroniques comme terrain d’observation, cette recherche étudie les fondements du commerce illégal de déchets dangereux des pays développés vers les PED. En effet, malgré la multiplication des législations, le problème des déchets dans les pays développés, loin d’être traité en amont, l’est en grande partie en aval par leur délocalisation dans les PED. Les deux lectures proposées, économique et institutionnelle, permettent de montrer comment les contraintes de coût de gestion des déchets dans les pays développés conjuguées à l’imperfection et à la non-application des législations conduisent à des comportements socialement irresponsables. À partir de là, l’implication des parties prenantes est suggérée comme solution pour éliminer ce type de comportements.Based on the analysis of the waste electrical and electronic equipments (WEEE, the research investigates the motivations for the illegal cross-border trade in hazardous wastes from developed countries to developing countries. Although many developed countries have implemented waste shipment regulations, they are passing the risks and costs of E-waste to developing countries. Indeed, E-waste is often sent for recycling and refurbishing in developing countries. The two-side proposed approach (i.e. economical and institutional suggests that both the cost for firms to comply with increasing regulations and the imperfect implementation of regulatory restrictions lead to socially irresponsible behaviours. An increasing and better involvement of stakeholders may be put forward as a solution.

    The accurate identification of modal damping ratios of Civil Engineering structures is a subject of major importance, as the amplitude of structural vibrations in resonance is inversely proportional to these coefficients. Their experimental identification can be performed either from ambient...... vibration or from free vibration tests. In the last case, the structural response after application of an impulse or after the application of harmonic loads can be used. Ambient vibration tests have the strong advantage of being more practical and economical. However, recent applications of both approaches...

    Full Text Available Les nombreuses quebradas, ravins à écoulement sporadique qui traversent le site de Quito, ont été systématiquement remblayées lors de l’urbanisation, pour servir notamment de zones de décharge plus ou moins contrôlée pour les déchets solides. À partir d’une cartographie diachronique, l’historique de ce remblaiement du réseau hydrographique est décrit, et les risques de nature morphoclimatique induits par ces profondes transformations, étudiés par ailleurs, sont brièvement évoqués. Ces zones spécifiques d’un site urbain de montagne relèvent d’un statut juridique de protection propre au réseau hydrographique en ville, lequel est profondément modifié dans la pratique après remblaiement, voire simplement oublié. Tout se passe comme si le remblaiement et l’urbanisation du réseau hydrographique faisaient l’objet d’un large consensus social, pour gagner de l’espace, donner une solution intra-urbaine à l’évacuation des déchets, et éradiquer des zones socialement incontrôlées. Les représentations sociales qui induisent une politique non explicite de gestion du site, sont analysées et discutées, au moment où les gestionnaires de la ville s’interrogent quant au bien-fondé de la poursuite du processus, alors que ce dernier se poursuit activement pour cacher la forte pollution du rio Machangara, principal émissaire du bassin.

    Ya-Lei Chen

    Full Text Available BACKGROUND: Melioidosis is a severe bacterial infection caused by Burkholderia pseudomallei with a high case-fatality rate. Epidemiological and animal studies show the possibility of inhalation transmission. However, no B. pseudomallei concentrations in ambient air have been researched. Here, we developed a method to quantify ambient B. pseudomallei and then measured concentrations of ambient B. pseudomallei during the typhoon season and the non-typhoon season to determine the factors influencing ambient B. pseudomallei levels. METHODS: We quantified ambient B. pseudomallei by using a filter/real-time qPCR method in the Zoynan Region in Kaohsiung, southern Taiwan. Twenty-four hour samples were collected at a sampling rate of 20 L/min every day from June 11 to December 21, 2012 including during the typhoon season (June to September and reference season (October to December. RESULTS: We successfully developed a filtration/real-time qPCR method to quantify ambient B. pseudomallei. To our knowledge, this is the first report describing concentrations of ambient B. pseudomallei. Ambient B. pseudomallei were only detected during the typhoon season when compared to the reference season. For the typhoons affecting the Zoynan Region, the positive rates of ambient B. pseudomallei were very high at 80% to 100%. During June to December, rainfall was positively correlated with ambient B. pseudomallei with a statistical significance. Sediment at a nearby pond significantly influenced the concentration of ambient B. pseudomallei. During the typhoon month, the typhoon was positively correlated with ambient B. pseudomallei whereas wind speed was reversely correlated with ambient B. pseudomallei. CONCLUSIONS: Our data suggest the possibility of transmission of B. pseudomallei via inhalation during the typhoon season.

    When people are aware of their lifestyle's ecological consequences, they are more likely to adjust their behavior to reduce their impact. Persuasive design that provides feedback to users without interfering with their primary tasks can increases the awareness of neighboring problems. As a case study of design for persuasion, we designed two ambient displays as desktop widgets. Both represent a users' computer usage time, but in different visual styles. In this paper, we present the results of a comparative study of two ambient displays. We discuss the gradual progress of persuasion supported by the ambient displays and the differences in users' perception affected by the different visualization styles. Finally, Our empirical findings lead to a series of design implications for persuasive media.

  17. Ambient air pollution and birth defects in brisbane, australia.

    Directory of Open Access Journals (Sweden)

    Craig A Hansen

    Full Text Available BACKGROUND: Birth defects are a major public health concern as they are the leading cause of neonatal and infant mortality. Observational studies have linked environmental pollution to adverse birth outcomes, including congenital anomalies. This study examined potential associations between ambient air pollution and congenital heart defects and cleft lip or palate among births in Brisbane, Australia (1998-2004. METHODS: Ambient air pollution levels were averaged over weeks 3-8 of pregnancy among 150,308 births. Using a case-control design, we used conditional logistic regression and matched cases to 5 controls. Analyses were conducted using all births, and then births where the mother resided within 6 and 12 kilometers of an ambient air quality monitor. FINDINGS: When analyzing all births there was no indication that ambient air pollution in Brisbane was associated with a higher risk of cardiac defects. Among births where the mother resided within 6 kilometers of an ambient air quality monitor, a 5 ppb increase in O(3 was associated with an increased risk of pulmonary artery and valve defects (OR 2.96, 95% CI: 1.34, 7.52 while a 0.6 ppb increase in SO(2 was associated with an increased risk of aortic artery and valve defects (OR 10.76, 95% CI: 1.50, 179.8. For oral cleft defects among all births, the only adverse association was between SO(2 and cleft lip with or without cleft palate (OR 1.27, 95% CI: 1.01, 1.62. However, various significant inverse associations were also found between air pollutants and birth defects. CONCLUSIONS: This study found mixed results and it is difficult to conclude whether ambient air pollution in Brisbane has an adverse association with the birth defects examined. Studies using more detailed estimates of air pollution exposure are needed.

  18. Ambient Seismic Imaging of Hydraulically Active Fractures at km Depths

    Science.gov (United States)

    Malin, P. E.; Sicking, C.

    2017-12-01

    Streaming Depth Images of ambient seismic signals using numerous, densely-distributed, receivers have revealed their connection to hydraulically active fractures at 0.5 to 5 km depths. Key for this type of imaging is very high-fold stacking over both multiple receives and periods of a few hours. Also important is suppression of waveforms from fixed, repeating sources such as pumps, generators, and traffic. A typical surface-based ambient SDI survey would use a 3D seismic receiver grid. It would have 1,000 to 4,000 uniformly distributed receivers at a density of 50/km2over the target. If acquired by borehole receivers buried 100 m deep, the density can be dropped by an order of magnitude. We show examples of the acquisition and signal processing scenarios used to produce the ambient images. (Sicking et al., SEG Interpretation, Nov 2017.) While the fracture-fluid source connection of SDI has been verified by drilling and various types of hydraulic tests, the precise nature of the signal's origin is not clear. At the current level of observation, the signals do not have identifiable phases, but can be focused using P wave velocities. Suggested sources are resonances of pressures fluctuations in the fractures, or small, continuous, slips on fractures surfaces. In either case, it appears that the driving mechanism is tectonic strain in an inherently unstable crust. Solid earth tides may enhance these strains. We illustrate the value of the ambient SDI method in its industrial application by showing case histories from energy industry and carbon-capture-sequestration projects. These include ambient images taken before, during, and after hydraulic treatments in un-conventional reservoirs. The results show not only locations of active fractures, but also their time responses to stimulation and production. Time-lapse ambient imaging can forecast and track events such as well interferences and production changes that can result from nearby treatments.

    2000-01-01

    An ambient pressure fuel cell system is provided with a fuel cell stack formed from a plurality of fuel cells having membrane/electrode assemblies (MEAs) that are hydrated with liquid water and bipolar plates with anode and cathode sides for distributing hydrogen fuel gas and water to a first side of each one of the MEAs and air with reactant oxygen gas to a second side of each one of the MEAs. A pump supplies liquid water to the fuel cells. A recirculating system may be used to return unused hydrogen fuel gas to the stack. A near-ambient pressure blower blows air through the fuel cell stack in excess of reaction stoichiometric amounts to react with the hydrogen fuel gas.

    In the next years, Mexico will face the following challenges: to maintain economic, social and urban rates of growth among others, higher than the demographic ones with the purpose of guaranteeing a better quality of life and mitigating gas discharges of green house effect without jeopardizing the development of the country. In an eminently urban country, these goals are made first in local form as it is the case of the metropolitan zone of the city of Mexico City (ZMCM), with different actions to mitigate the effects of the high development that this region has had. The objective is to try to modify the perception that one has had of it at the beginning of the 90's decade when it was denominated by Time magazine (January 1989) as the waiting room of an ecological Hiroshima and as urban gas chamber. The official answer conformed it: the creation of a Network of Atmospheric Monitoring, the implantation of programs like the Pro Air, the Today Does Not Circulate among others. Even with these actions in mind the objective does not glimpse clearly in the short term to reach a development with environmental sustainability. The work premise is to analyze different actions oriented to diminish in a 20% the emissions of polluting agents using clean and renewable energies such as natural gas and solar, among others, without trying to originate radical changes and that can be applied in other cities of the country. In parallel form one sets out to sustain these actions with the present environmental programs and to quantify the sustainability with three indicators (variation of polluting emissions, the level of fossil resources and costs to the health). The development of the investigation is based on the definition of a reference scenario (on the base of the present tendencies) and another alternative scenario having as analysis tool the computational platform denominated ENPEP (Energy and Power Evaluation Program) developed by National Argonne National Laboratory

    INTRODUCTION : Des milliers de personnes souffrent actuellement de douleur chronique (DC) pour laquelle la prise en charge s’avère souvent inadéquate. Au Québec, les infirmières qui oeuvrent dans les Groupes de médecine de famille (GMF) jouent un rôle clé dans le suivi des personnes aux prises avec des problèmes de santé chroniques dont la DC. OBJECTIFS : Cette étude a pour objectifs de décrire les activités réalisées par les infirmières œuvrant en GMF en lien avec la gestion de la douleur chez la clientèle souffrant de DC, ainsi que les barrières à ces activités. MÉTHODE : Un dispositif descriptif corrélationnel transversal de type enquête postale a été utilisé. La population accessible à l’étude comprend les infirmières qui figurent sur la liste des membres de l’Ordre des infirmières et infirmiers du Québec travaillant en GMF. L’ensemble des infirmières figurant sur cette liste ayant consenti à être contactées à leur domicile pour des fins de recherche ont été contactées. Un questionnaire postal auto-administré (Pain Management Activities Questionnaire) a été complété par 53 infirmières travaillant en GMF. RÉSULTATS : Les trois activités le plus souvent réalisées par les infirmières sont d’établir une relation thérapeutique avec le client; de discuter avec le médecin de l’efficacité des mesures thérapeutiques et de faire un enseignement personnalisé au client. Les infirmières ont la perception qu’elles rencontrent en moyenne 2,68 personnes par semaine qui souffrent de DC. La méconnaissance des interventions possibles en douleur (71,7%) et la non-disponibilité de l’information sur la gestion de la douleur (52,8%) constituent les principales barrières selon les infirmières sondées. CONCLUSION : Les infirmières au sein des GMF font actuellement peu d’activités en gestion de la DC probablement en raison du manque de reconnaissance de la DC. PMID:25848847

    This study aimed to evaluate the correlation between ambient concentrations of air pollutants and first-trimester spontaneous abortion. This was a retrospective case–control study, which was conducted on 296 women from June 2010 to February 2011 in Tehran, Iran. Cases were 148 women who experienced a spontaneous abortion before 14 weeks of gestation while the controls were 148 pregnant women after 14 weeks of gestation and groups were matched on sociodemographics and obstetrics characteristics. The samples were recruited randomly from 10 hospitals. In total, pollutants concentrations were collected at 29 stations hourly throughout the study area. We estimated the mean exposure for each participant and investigated the association between spontaneous abortion and ambient pollutants. Findings demonstrated that the average of ambient air pollutants in the cases was significantly higher than in the controls (P abortion in the areas with higher concentrations of CO, NO₂, O₃ and PM₁₀ were 1.98, 0.96, 0.94 and 1.01, respectively (P abortion (P > 0.05). Our findings suggest that pregnant women exposed to ambient air pollutants may be at increased risk of spontaneous abortion. Confirmation by further research is needed.

    2013-01-01

    In the current study participants explored a desktop virtual environment (VE) representing a suburban neighborhood with signs of public disorder (neglect, vandalism, and crime), while being exposed to either room air (control group), or subliminal levels of tar (unpleasant; typically associated with burned or waste material) or freshly cut grass (pleasant; typically associated with natural or fresh material) ambient odor. They reported all signs of disorder they noticed during their walk together with their associated emotional response. Based on recent evidence that odors reflexively direct visual attention to (either semantically or affectively) congruent visual objects, we hypothesized that participants would notice more signs of disorder in the presence of ambient tar odor (since this odor may bias attention to unpleasant and negative features), and less signs of disorder in the presence of ambient grass odor (since this odor may bias visual attention toward the vegetation in the environment and away from the signs of disorder). Contrary to our expectations the results provide no indication that the presence of an ambient odor affected the participants' visual attention for signs of disorder or their emotional response. However, the paradigm used in present study does not allow us to draw any conclusions in this respect. We conclude that a closer affective, semantic, or spatiotemporal link between the contents of a desktop VE and ambient scents may be required to effectively establish diagnostic associations that guide a user's attention. In the absence of these direct links, ambient scent may be more diagnostic for the physical environment of the observer as a whole than for the particular items in that environment (or, in this case, items represented in the VE).

    Les laboratoires de recherche sur l'assistance aux personnes âgées ou avec une déficience cognitive possèdent actuellement peu de solutions réellement déployables dans un habitat. Ils se heurtent donc à un problème de transfert de leurs applications vers des conditions réelles. En effet, la plupart de ces applications ont besoin de serveurs et d'équipements coûteux ou complexes à installer. La nouvelle tendance des laboratoires de recherche est donc à l'élaboration de solutions plug and play. En effet, ces dernières sont facilement et rapidement installables dans un habitat. C'est dans cette optique que mon présent projet de recherche a été réalisé. L'objectif de cette maîtrise est de proposer une solution à ce problème en déployant des plateformes embarquées pouvant supporter des applications multimédias distribuées. Ces plateformes appelées noeuds multimédias ont la particularité d'être simples d'installation, peu intrusives et de faibles coûts. Afin de tester la gestion du réseau de noeuds multimédias, une application distribuée de suivi multimédia à travers un habitat intelligent a été réalisée dans l'appartement du laboratoire DOMUS.

FONTES DOS DADOS: Foi realizada uma pesquisa utilizando as bases de dados MEDLINE/PubMed e SciELO. Foram revisados artigos de 1990 a 2010, além de capítulos de livros relacionados à pediatria ambiental. SÍNTESE DOS DADOS: Há uma variedade significativa de fatores que tornam as crianças altamente vulneráveis à exposição a riscos ambientais, associados principalmente ao consumo comparativamente maior de água, comida e ar por parte da criança, em relação ao seu peso corporal. De acordo com a Organização Mundial de Saúde, mais de 3 milhões de crianças menores de 5 anos morrem devido a doenças relacionadas ao meio ambiente. Aproximadamente 30-40% das doenças pediátricas estão relacionadas a fatores ambientais. As crianças estão constantemente expostas a vários riscos ambientais para a saúde, dentre os quais se destacam: água contaminada, falta de condições adequadas de saneamento, poluição do ar, vetores de doenças, perigos químicos, injúrias e acidentes. CONCLUSÕES: Atualmente, os pediatras são desafiados a tratar das necessidades de saúde ligadas à pediatria ambiental. A história pediátrica deve ser mais abrangente, acrescentando-se questões pontuais que ajudem a identificar potenciais riscos ambientais. A conscientização e o entendimento sobre os efeitos nocivos das várias condições ambientais e o conhecimento sobre as medidas de prevenção relacionadas resultarão em intervenções oportunas e adequadas que melhorarão a saúde e o desenvolvimento das nossas crianças.

Le sexe ratio était à 4,5 en faveur des hommes. L'âge moyen des patients est de 29 ans. Concernant la gestion des voies aériennes ; une intubation standard à l’aide de laryngoscope a été retenue chez la plupart des patients (17 patients). L’intubation vigile sous fibroscopie a été réalisée chez 3 patients, une trachéotomie première a été faite chez une patiente et une intubation rétrograde salvatrice a été retenue chez une autre patiente. Conclusion Deux défis guettent tout anesthésiste prenant en charge des patients présentant une cellulite cervico-faciale, un risque de ventilation difficile et un souci d’intubation laborieuse. Les deux risques sont à envisager de principe, et où une stratégie anticipative devra être élaborée. Introduction Maxillofacial cellulitis is a medical-surgical emergency. These patients are most often treated in the operating room on the one hand for identifying and draining the collections and on the other hand for bacteriological samples. The type of anesthetic technique used exposes to potential difficulties in controlling the upper airways. Methods

Dans le contexte des mutations en cours, face aux risques de déficits en eau et à la nécessité d'un développement économique et social équilibré, ces caractéristiques, parmi d'autres, font de la Jeffara tunisienne un cas d'étude exemplaire des difficultés que pose la gestion intégrée de l'eau. Celle-ci doit prendre en compte les différentes sources d'approvisionnement ainsi que les différents usages associés, et donc l'identification des territoires pertinents pour cette  gestion, compte tenu des relations amont-aval naturelles et artificielles d'une part, et des cohérences institutionnelles et sociales d'autre part.The current situation of the water resources and their uses in South-Eastern Tunisia presents stakes which are common to many areas of the Mediterranean basin : limited and already largely exploited resources to address the growth of the needs, the increasing use of so-called non conventional resources, a competition between sectoral uses of water, an increasing merchandising of the resources, and constraining climatic conditions which reinforce the tensions around water. In the context of the changes in progress, facing the hazard of water deficits and with the need for a balanced economic and social development, these characteristics, among others, make Tunisian Jeffara be an exemplary case of study of the difficulties raised by the integrated water resources management.

    Ambient Intelligence (AmI) is a new paradigm in information technology aimed at empowering people's capabilities by the means of digital environments that are sensitive, adaptive, and responsive to human needs, habits, gestures, and emotions. This futuristic vision of daily environment will enable innovative human-machine interactions characterized by pervasive, unobtrusive and anticipatory communications. Such innovative interaction paradigms make ambient intelligence technology a suitable candidate for developing various real life solutions, including in the health care domain. This survey will discuss the emergence of ambient intelligence (AmI) techniques in the health care domain, in order to provide the research community with the necessary background. We will examine the infrastructure and technology required for achieving the vision of ambient intelligence, such as smart environments and wearable medical devices. We will summarize of the state of the art artificial intelligence methodologies used for developing AmI system in the health care domain, including various learning techniques (for learning from user interaction), reasoning techniques (for reasoning about users' goals and intensions) and planning techniques (for planning activities and interactions). We will also discuss how AmI technology might support people affected by various physical or mental disabilities or chronic disease. Finally, we will point to some of the successful case studies in the area and we will look at the current and future challenges to draw upon the possible future research paths.

  18. Effects of ambient conditions on fuel cell vehicle performance

    Science.gov (United States)

    Haraldsson, K.; Alvfors, P.

    Ambient conditions have considerable impact on the performance of fuel cell hybrid vehicles. Here, the vehicle fuel consumption, the air compressor power demand, the water management system and the heat loads of a fuel cell hybrid sport utility vehicle (SUV) were studied. The simulation results show that the vehicle fuel consumption increases with 10% when the altitude increases from 0 m up to 3000 m to 4.1 L gasoline equivalents/100 km over the New European Drive Cycle (NEDC). The increase is 19% on the more power demanding highway US06 cycle. The air compressor is the major contributor to this fuel consumption increase. Its load-following strategy makes its power demand increase with increasing altitude. Almost 40% of the net power output of the fuel cell system is consumed by the air compressor at the altitude of 3000 m with this load-following strategy and is thus more apparent in the high-power US06 cycle. Changes in ambient air temperature and relative humidity effect on the fuel cell system performance in terms of the water management rather in vehicle fuel consumption. Ambient air temperature and relative humidity have some impact on the vehicle performance mostly seen in the heat and water management of the fuel cell system. While the heat loads of the fuel cell system components vary significantly with increasing ambient temperature, the relative humidity did not have a great impact on the water balance. Overall, dimensioning the compressor and other system components to meet the fuel cell system requirements at the minimum and maximum expected ambient temperatures, in this case 5 and 40 °C, and high altitude, while simultaneously choosing a correct control strategy are important parameters for efficient vehicle power train management.

Chegamos a "era da revolução ambiental", e o ambiente não somente aparece como um conjunto de problemas relativos ao controle da contaminação, mas representa um custo no crescimento econômico. Neste sentido, o contador precisa de uma formação que se estenda além dos limites das técnicas e dos procedimentos. É necessário acrescentar o registro contábil do meio ambiente, dada a velocidade de sua afetação e a influência do mundo atual na utilização e disposição dos recursos naturais. Deve ser considerado como um dos princípios contábeis, onde é um desafio para a contabilidade. Precisa ser considerada como uma ciência contábil integrada, pois com a ciência ecológica e outras ciências são responsáveis pela natureza onde devem ser aplicados critérios de proteção ambiental, demonstrando que os recursos naturais constituem nosso principal capital.

La caracterisation et les calculs theoriques des emissions atmospheriques aux installations des sites no.1 et no.2 presentent des resultats qui sont en dessous des valeurs reglementaires pour des conditions d'operation normales en periode hivernale et par consequent, a de plus fortes demandes energetiques. Ainsi, pour une demande energetique plus basse, le taux de contaminants dans les emissions atmospheriques pourrait egalement etre en dessous des reglementations municipales et provinciales en vigueur. Dans la perspective d'une nouvelle reglementation provinciale, dont les termes sont discutes depuis 2005, il serait souhaitable que le proprietaire des infrastructures visees participe aux echanges avec le Ministere du Developpement Durable, de l'Environnement et des Parcs (MDDEP) du Quebec. En effet, meme si le principe de droit acquis permettrait d'eviter d'etre assujetti a la nouvelle reglementation, l'application de ce type de principe ne s'inscrit pas dans ceux d'un developpement durable. L'âge avance des installations etudiees implique la planification d'un entretien rigoureux afin d'assurer les conditions optimales de combustion en fonction du type de combustible.

    At present, equipment for the detection of gamma radiation existing in the environment is being developed to protect the population in the Mexico country. The Instituto Nacional de Investigaciones Nucleares (ININ) implemented the gamma radiation monitoring probe (GRMP), which is an instrument used to measure the ionizing radiation in the environment and this in turn communicates with the National Network for Radiological Environmental Monitoring, which detects in real time the gamma radiation. The probes are located in strategic points in the different States of the Mexican Republic and due to their exposure to different types of climate, cause different damages to the case of the GRMP. Due to this situation is that this work is focused on performing different tests to maintain the case in order to validate the problems encountered and investigate new improvements for optimal operation.

Es este trabajo se observa el mismo problema pero desde la perspectiva recientemente esbozada por los movimientos sociales: la del racismo ambiental o la desigual distribución de los deshechos del desarrollo y el consumo. De esta manera se revisan sucintamente los principales conflictos que han surgido en el último tiempo a lo largo del país entre empresas públicas y privadas y comunidades locales y originarias. Así mismo se examinan las formas de organización que estas últimas han asumido y el estado actual de articulación entre ellas. De la revisión de la situación se concluye que estamos ante el surgimiento de un actor de nuevo tipo, que surge de las contradicciones del Chile neoliberal y que se diferencia del movimiento ecologista por vincular sus reivindicaciones a la defensa del territorio y al derecho a la autodeterminación de los pueblos.

Los sistemas incluidos son: ABO, MN, Ss, DI, P, Cc, Dd y Ee. En el caso de Bolivia, Paraguay y el Chaco Argentino, los datos fueron obtenidos de la bibliografía. La relación entre las poblaciones y diferentes criterios de agrupación (Ambiente, País, Grupo Lingüístico y Altitud fueron evaluadas por medio de Análisis Discriminante. Se consideró el porcentaje de casos correctamente clasificados como medida de la relación entre el conjunto de variables analizadas y el criterio de agrupación. Se encontró que tanto las categorías geoestructurales como lingüísticas establecidas tienen mayor relación con la estructura genética de las poblaciones incluidas en el análisis que las fronteras nacionales, por lo que se concluye que el aislamiento reproductivo entre poblaciones, necesario para la diferenciación, se produce por diferencias culturales o del territorio de ocupación antes que por las fronteras políticas establecidas.

    Full Text Available Distintas formas de interpretar las condiciones ambientales han llevado al desarrollo de conceptos tales como edificio enfermo, calidad del aire o calidad ambiental interior, todos ellos encaminados a entender la complejidad de los contaminantes en los ambientes cerrados y las implicaciones sobre la salud de la población. La propuesta de "Calidad ambiental interior" es un avance conceptual y operativo que supera ampliamente a los anteriores, puesto que orienta las acciones hacia ambientes saludables sin limitar al aire la idea de contaminación. El objetivo del trabajo es identificar las competencias y el marco legislativo que permiten actuar en la prevención de riesgos asociados a la exposición de contaminantes en ambientes interiores. Óptimas condiciones en los ambientes interiores deben redundar en salud, bienestar y confort, tanto en lo que respecta a la vida laboral como a los ámbitos donde se desarrollan las actividades cotidianas extralaborales, escolares, de descanso y de ocio. La sociedad actual exige lugares seguros, limpios y bien climatizados, para lo que es necesario integrar percepciones y exigencias de los habitantes y alcanzar un óptimo equilibrio entre estándares sociales, uso de la energía y desarrollo sostenible, buscando confort sin contaminar y sin aumentar el consumo de fuentes energéticas que degraden el medio ambiente. El desarrollo legislativo se orienta a la seguridad y la salud en los lugares de trabajo y la regulación de las sustancias químicas. La Sanidad Ambiental lleva a cabo tareas de prevención y control, participa en la ejecución de convenios internacionales de reducción de contaminantes y desechos y promueve acciones para el desarrollo de la Estrategia Europea de Salud y Medio Ambiente.

    Robertson, Sarah; Miller, Mark R

    2018-01-03

    Air pollution is a growing public health concern of global significance. Acute and chronic exposure is known to impair cardiovascular function, exacerbate disease and increase cardiovascular mortality. Several plausible biological mechanisms have been proposed for these associations, however, at present, the pathways are incomplete. A seminal review by the American Heart Association (2010) concluded that the thrombotic effects of particulate air pollution likely contributed to their effects on cardiovascular mortality and morbidity. The aim of the current review is to appraise the newly accumulated scientific evidence (2009-2016) on contribution of haemostasis and thrombosis towards cardiovascular disease induced by exposure to both particulate and gaseous pollutants.Seventy four publications were reviewed in-depth. The weight of evidence suggests that acute exposure to fine particulate matter (PM 2.5 ) induces a shift in the haemostatic balance towards a pro-thrombotic/pro-coagulative state. Insufficient data was available to ascertain if a similar relationship exists for gaseous pollutants, and very few studies have addressed long-term exposure to ambient air pollution. Platelet activation, oxidative stress, interplay between interleukin-6 and tissue factor, all appear to be potentially important mechanisms in pollution-mediated thrombosis, together with an emerging role for circulating microvesicles and epigenetic changes.Overall, the recent literature supports, and arguably strengthens, the contention that air pollution contributes to cardiovascular morbidity by promoting haemostasis. The volume and diversity of the evidence highlights the complexity of the pathophysiologic mechanisms by which air pollution promotes thrombosis; multiple pathways are plausible and it is most likely they act in concert. Future research should address the role gaseous pollutants play in the cardiovascular effects of air pollution mixture and direct comparison of potentially

    Full Text Available Les ressources forestières constituent un capital naturel pour l’approvisionnement des populations locales, en bois, en plantes aromatiques et médicinales et en parcours pour le pâturage. Ces multiples usages ont conduit ces populations à mettre en place une gestion communautaire et très ancienne de ces ressources. Depuis 2002, l’administration des Eaux et Forêts a mis en place une politique forestière basée sur une stratégie de gestion participative. Nous avons étudié les formes de gestion communautaire et par l’administration des ressources forestières dans quatre communes rurales du Parc National d’Ifrane. L’administration organise une mise en défens, fondée sur l’implication et la responsabilisation des populations usagères, organisée en associations sylvo-pastorales ou en coopératives forestières, à travers une incitation financière sous forme de compensation. Ce mécanisme a permis d’obtenir un certain nombre d’acquis : conscientisation des populations vis-à-vis de la mise en défens, investissement des sommes de la compensation dans des projets de développement local, etc. Cependant, ce mécanisme présente certaines fragilités, notamment un risque de non durabilité des mises en défens (du fait que celles-ci ne sont financées que par le budget de l’Etat et un contrôle social plus faible dans les nouvelles associations qui n’ont pas la même légitimité pour prendre des décisions au nom du collectif que les anciennes jmaa.

We aimed to quantify the association of ambient temperature with the risk of ICH in the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial (INTERACT2 participants on an hourly timescale.INTERACT2 was an international, open, blinded endpoint, randomized controlled trial of patients with spontaneous ICH (<6h of onset and elevated systolic blood pressure (SBP, 150-220 mmHg assigned to intensive (target SBP <140 mmHg or guideline-recommended (SBP <180 mmHg BP treatment. We linked individual level hourly temperature to baseline data of 1997 participants, and performed case-crossover analyses using a distributed lag non-linear model with 24h lag period to assess the association of ambient temperature and risk of ICH. Results were presented as overall cumulative odds ratios (ORs and 95% CI.Low ambient temperature (≤10°C was associated with increased risks of ICH: overall cumulative OR was 1.37 (0.99-1.91 for 10°C, 1.92 (1.31-2.81 for 0°C, 3.13 (1.89-5.19 for -10°C, and 5.76 (2.30-14.42 for -20°C, as compared with a reference temperature of 20°C.There was no clear relation of low temperature beyond three hours after exposure.

In recent years, light has been used to create ambient systems to display information. Examples of ambient light systems range from simple notification systems such as displaying messages or calendar event reminders, to more complex systems such as focusing on conveying information regarding health activity tracking. However, for ambient light systems, there is a broad design space that lacks guidelines on when to make use of light displays and how to design them. In this paper we provide a systematic overview of existing ambient light systems over four identified information classes derived from 72 existing ambient light systems. The most prominent encoding parameters among the surveyed ambient light systems are color, brightness, and their combination. By analyzing existing ambient light systems, we provide a first step towards developing guidelines for designing future ambient light systems.

    Full Text Available L’organisation nationale en matière d’évaluation et de gestion des risques est en cours de modifications depuis quelques années. Organisée par une loi en 1998, la création d’agences pour la sécurité sanitaire des aliments, des produits de santé et de l’environnement a marqué une étape. D’autres domaines sont en cours de réorganisation comme la sûreté nucléaire et la radioprotection. La mise en oeuvre de la directive SEVESO II peut aussi influer sur la gestion des installations industrielles classées dites « SEVESO ». Des « événements » comme la crise de la vache folle ou celle du sang contaminé ont joué un rôle dans les évolutions, mais l’émergence de nouveaux principes de gestion des risques au sein de la communauté internationale a aussi influé fortement sur les choix faits et les discussions. Le travail présenté ici est un travail préliminaire, qui visait à identifier les grandes lignes des réponses apportées dans les différents domaines à des questions comme celles du rôle des différentes institutions en matière d’évaluation et de gestion. L’approche comparative suivie ici est trop globale pour que tous les éléments de chaque système réglementaire soit décrit et certains aspects sont simplifiés. En revanche, ce type de comparaison met en lumière des contrastes notables quant aux solutions trouvées pour articuler le travail d’évaluation des risques et les prises de décision relevant des autorités.

    Several research programs are tackling the use of Wireless Sensor Networks (WSN) at specific fields, such as e-Health, e-Inclusion or e-Sport. This is the case of the project "Ambient Intelligence Systems Support for Athletes with Specific Profiles", which intends to assist athletes in their training. In this paper, the main developments and outcomes from this project are described. The architecture of the system comprises a WSN deployed in the training area which provides communication with athletes' mobile equipments, performs location tasks, and harvests environmental data (wind speed, temperature, etc.). Athletes are equipped with a monitoring unit which obtains data from their training (pulse, speed, etc.). Besides, a decision engine combines these real-time data together with static information about the training field, and from the athlete, to direct athletes' training to fulfill some specific goal. A prototype is presented in this work for a cross country running scenario, where the objective is to maintain the heart rate (HR) of the runner in a target range. For each track, the environmental conditions (temperature of the next track), the current athlete condition (HR), and the intrinsic difficulty of the track (slopes) influence the performance of the athlete. The decision engine, implemented by means of (m, s)-splines interpolation, estimates the future HR and selects the best track in each fork of the circuit. This method achieves a success ratio in the order of 80%. Indeed, results demonstrate that if environmental information is not take into account to derive training orders, the success ratio is reduced notably.

    In this paper a new frequency domain technique is introduced for the modal identification from ambient responses, i.e. in the case where the modal parameters must be estimated without knowing the input exciting the system. By its user friendliness the technique is closely related to the classical...... approach where the modal parameters are estimated by simple peak picking. However, by introducing a decomposition of the spectral density function matrix, the response can be separated into a set of single degree of freedom systems, each corresponding to an individual mode. By using this decomposition...

    Full Text Available A case-control study of Parkinson's disease (PD was conducted in the city of Rio de Janeiro based on the assumption that neurotoxins with secondary parkinsonian action may be related to the development of Parkinson's disease. Ninety-two subjects with PD and 110 controls were queried through a questionnaire in order to investigate possible risk factors for the disease. The following factors were studied: herbicides/pesticides, exposure to chemicals, ingestion of drugs with secondary PD effects, rural life, water well source, family history, cranial trauma and cigarette smoking. Study of mentioned factors was achieved through univariate, stratified and multivariate analyses. Univariate and multivariate analyses demonstrated that PD was positively associated with family history (OR = 14.5; CI = 2.98 - 91.38, with the use of drugs with secondary PD action (OR = 11.01; CI = 3.41 - 39.41 and with exposure to chemical agents (OR = 5.87; CI = 1.48 - 27.23. PD was found to be inversely associated with cigarette smoking (OR = 0.39; IC = 0.16 - 0.95. Stratified analysis only confirmed family history and drug use, besides demonstrating that cigarette consumption could be a protection factor, when aforementioned factors were involved. This study might be a warning as to the cares that need to be taken regarding drug use and occupational exposure to chemical agents, as both types of substances present secondary PD action.Um estudo caso-controle foi realizado na cidade do Rio de Janeiro, partindo-se do pressuposto de que neurotoxinas com ação parkinsoniana secundária poderiam facilitar a ocorrência da doença de Parkinson.

    2013-03-01

    Purpose: This study examines the relationship between ambient lighting level and image manipulation. Method: Academic radiographers (n=10), with experience in observer performance studies, each assessed 70 postero-anterior projection radiographs of the wrist / scaphoid in both low (12.5 lux) and high (150 lux) ambient lighting. Half of the images featured one or more acute fractures and the remainder did not. Observers were encouraged to window the images to a level they felt was appropriate and, requested to rate their confidence that an acute fracture was present, marking the locations of any suspected acute fractures on the image. The images were displayed on a secondary-class monitor using Ziltron software, which recorded the adjustments to brightness and contrast made for each image. The images were presented in different orders for each lighting level to reduce potential memory effects. Results: Student's t-tests were applied to compare the mean brightness and contrast adjustments made to the images in each ambient lighting level. Tests were carried out to include all images, only positive cases, and only cases where observers elected to change the brightness and/or contrast. No statistically significant differences were noted except when images where no brightness/contrast adjustments were made were discounted. In that case, mean brightness levels were slightly higher in the high ambient light level (p=0.049). Conclusion: No convincing difference in adjustments of brightness and contrast between high and low ambient lighting levels, although further research is warranted.

  12. The Aesthetics of the Ambient Video Experience

    Directory of Open Access Journals (Sweden)

    Jim Bizzocchi

    2008-01-01

    Full Text Available Ambient Video is an emergent cultural phenomenon, with roots that go deeply into the history of experimental film and video art. Ambient Video, like Brian Eno's ambient music, is video that "must be as easy to ignore as notice" [9]. This minimalist description conceals the formidable aesthetic challenge that faces this new form. Ambient video art works will hang on the walls of our living rooms, corporate offices, and public spaces. They will play in the background of our lives, living video paintings framed by the new generation of elegant, high-resolution flat-panel display units. However, they cannot command attention like a film or television show. They will patiently play in the background of our lives, yet they must always be ready to justify our attention in any given moment. In this capacity, ambient video works need to be equally proficient at rewarding a fleeting glance, a more direct look, or a longer contemplative gaze. This paper connects a series of threads that collectively illuminate the aesthetics of this emergent form: its history as a popular culture phenomenon, its more substantive artistic roots in avant-garde cinema and video art, its relationship to new technologies, the analysis of the viewer's conditions of reception, and the work of current artists who practice within this form.

    Full Text Available Suite aux grandes mutations des années 60-70 en Camargue gardoise et à l’obsolescence du Traité des Marais qui réglait la gestion collective des niveaux d’eau, les acteurs économiques liés à l’eau se sont positionnés sur des logiques individualistes. L’eau est devenue l’objet de maints conflits avec de graves conséquences sur les ressources et les milieux. La mise en œuvre d’une Charte de l’environnement et d’un SAGE au début des années 90 a constitué les prémices du retour du " collectif " dans la gestion de l’eau. Mais on est encore loin de l’eau comme vecteur d’une construction territoriale à travers une communauté de projet liée à l’eau.

    Full Text Available Il mercato delle costruzioni in Italia soffre problemi di maturità da molto tempo. Dagli anni ’90, infatti, per superare i fatti di tangentopoli venne riformata la legislazione dei lavori pubblici per giungere a livelli di competizione maggiori e più simili a quelli esistenti in Europa.  In questo contesto le imprese che per la loro struttura culturale, organizzativa e produttiva mostravano maggiore sensibilità a tali aspetti avviarono processi di formazione e riorganizzazione introducendo specifiche procedure mirate alla gestione completa dei progetti trasformandosi così da imprese di sola produzione a imprese operanti per progetti.La presente memoria vuole descrivere il sistema di gestione attuato, le modifiche ed i miglioramenti che si sono susseguiti nel tempo,  la sua struttura organizzativa e gli strumenti di lavoro messi a disposizione.A conclusione verrà illustrata l’applicazione al caso concreto della costruzione del nuovo impianto di trattamento e recupero di rifiuti urbani.

    Full Text Available Raffaello Sanzio intuì per primo che il mondo antico, come lo vedevano i suoi occhi, non era che l’eco sbiadita di quella ricchezza che pur doveva caratterizzarne l’esperienza artistica. Oggi la tecnologia permette di realizzare il sogno di Raffaello e di restituire le immagini delle antiche architetture, rivoluzionando la percezione del patrimonio culturale da parte del pubblico moderno. La nostra esperienza decennale nel settore della comunicazione del bene culturale ha consentito di confrontarci con diversi casi: dalla Domus Aurea, all'Ara Pacis; dai filmati divulgativi agli applicativi pensati per le postazioni fisse dei musei, fino alla creazione di software per la gestione dei dati degli scavi archeologici.

Trois étapes structurent cette réflexion questionnant la transition supposée entre une gestion des risques naturels et une gestion durable des territoires soumis aux risques naturels : une association toute relative, un lien logique mais limité sur le terrain, une relation surtout indirecte.

    2014-11-01

    The accurate prediction and control of the interaction of liquids with hot surfaces is paramount in numerous areas, including cooling applications. We present results illustrating the effect of ambient pressure on the temperature required for a droplet to levitate over a hot surface, i.e., the Leidenfrost temperature. In the present study the dependence of wetting and levitating temperatures on ambient pressure in a range of subatmospheric pressures is reported. Experimental data indicate that the Leidenfrost temperature decreases with decreasing pressure at subatmospheric pressures. A physical approach for the dependence of Leidenfrost temperature on ambient pressure, based on an analogy with saturation pressure dependence, is proposed. Furthermore, previous literature data for pressures above atmospheric are also included in the analysis to support and validate the proposed approach. In addition, the effect of substrate material, substrate roughness, and type of fluid on the Leidenfrost temperature is discussed.

    2015-08-01

    Effective provision of care and assistance services in ambient assisted living requires the involvement and collaboration of multiple stakeholders. To support such collaboration, the development of an ecosystem of products and services for active ageing plays an important role. This article introduces a conceptual architecture that supports such care ecosystem. In order to facilitate understanding and better interrelate concepts, a 3-layered model is adopted: Infrastructure layer, Care and assistance services layer and Ambient Assisted Living ecosystem layer. A holistic perspective of ambient assisted living, namely considering four important life settings is adopted: (1) independent living; (2) health and care in life; (3) occupation in life and (4) recreation in life. The proposed architecture is designed in the context of a national Portuguese project and in accordance with the findings of a large European road mapping initiative on ICT and ageing.

  20. Ambient environment in the coal mining complexes

    1998-01-01

    Environment is all pervading and therefore associated with all individuals. The ambient environment with respect to any activity lies a little outside and the receiving body outside the active zone denotes ambient environment. Basically, air quality and noise level are two physical ingredients whose assessment gives an idea of impact on the ambience. Though largely blamed for polluted conditions, the general ambient conditions in the coal fields do not show a tardy image. Being a low level dispersion industry, its impact remains concentrated in the active core zone. This has been brought out here. The paper presents the status of air quality, and noise level in some coal fields in India. It also discloses a brighter future and sustainable development due to increased concern for environment.

    Le reseau de distribution et de transport de l'electricite se modernise dans plusieurs pays dont le Canada. La nouvelle generation de ce reseau que l'on appelle smart grid, permet entre autre l'automatisation de la production, de la distribution et de la gestion de la charge chez les clients. D'un autre cote, des appareils domestiques intelligents munis d'une interface de communication pour des applications du smart grid commencent a apparaitre sur le marche. Ces appareils intelligents pourraient creer une communaute virtuelle pour optimiser leurs consommations d'une facon distribuee. La gestion distribuee de ces charges intelligentes necessite la communication entre un grand nombre d'equipements electriques. Ceci represente un defi important a relever surtout si on ne veut pas augmenter le cout de l'infrastructure et de la maintenance. Lors de cette these deux systemes distincts ont ete concus : un systeme de communication peer-to-peer, appele Ring-Tree, permettant la communication entre un nombre important de noeuds (jusqu'a de l'ordre de grandeur du million) tel que des appareils electriques communicants et une technique distribuee de gestion de la charge sur le reseau electrique. Le systeme de communication Ring-Tree inclut une nouvelle topologie reseau qui n'a jamais ete definie ou exploitee auparavant. Il inclut egalement des algorithmes pour la creation, l'exploitation et la maintenance de ce reseau. Il est suffisamment simple pour etre mis en oeuvre sur des controleurs associes aux dispositifs tels que des chauffe-eaux, chauffage a accumulation, bornes de recharges electriques, etc. Il n'utilise pas un serveur centralise (ou tres peu, seulement lorsqu'un noeud veut rejoindre le reseau). Il offre une solution distribuee qui peut etre mise en oeuvre sans deploiement d'une infrastructure autre que les controleurs sur les dispositifs vises. Finalement, un temps de reponse de quelques secondes pour atteindre 1'ensemble du reseau peut etre obtenu, ce qui est

    Full Text Available O cuidado ambiental vem sendo marcado pela tônica da conservação e da promoção da sustentabilidade. A premente necessidade de um dado compromisso e educação ambiental e de condutas pró-ambientais vem sendo defendida em vários contextos: na mídia, nas políticas públicas, por meio de campanhas sazonais. Todavia, pouco se descreve acerca do sentido presente nos modos de cuidado configurados a partir da inter-relação pessoa-ambiente. Nesta perspectiva, este estudo objetivou promover um possível diálogo a partir das contribuições da Psicologia Ambiental e da Logoterapia visando aproximar a noção de cuidado ambiental, delineada pela Psicologia Ambiental, à ideia de responsabilidade, como defendida pela Logoterapia, por meio de uma revisão bibliográfica. As articulações propositadas corroboraram, portanto, para acenar que a relação pessoa-ambiente pode ser arraigada em qualidade se a responsabilidade é reconhecida em sua propriedade de potencial humano, o que pode favorecer na emergência do sentido das atitudes e condutas pró-ambientais e explicitar o caráter de tarefa única e irrepetível inerente à vida.

    Full Text Available There is a growing evidence on the hazards of ambient air pollution on fetal development. Several review articles have been published on the adverse fetal outcomes including low birth weight, preterm birth, small-for-gestational age, and congenital anomalies. Recent studies have linked ambient air pollution to gestational hypertension, and preeclampsia which may be related to the detrimental effect of ambient air pollution on placental growth and function. Short-term and long-term exposure to particulate air pollution may cause systemic inflammatory response which may trigger preterm delivery in pregnant women. Environmental toxic chemicals that alter intrauterine environment disregulates fetal epigenome causing epigenetic-mediated changes in gene expression that may be linked to later childhood and adulthood diseases. Exposure to ambient air pollution during the whole pregnancy especially in third-trimester may cause intrauterine vitamin D deficiency which is critical for the normal development of the lung, and immune system in fetus. However, more research is needed to understand the cause and effect interaction between air pollution and fetal development. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

  3. Setting priorities for ambient air quality objectives

    International Nuclear Information System (INIS)

    2004-10-01

    Alberta has ambient air quality objectives in place for several pollutants, toxic substances and other air quality parameters. A process is in place to determine if additional air quality objectives are required or if existing objectives should be changed. In order to identify the highest priority substances that may require an ambient air quality objective to protect ecosystems and public health, a rigorous, transparent and cost effective priority setting methodology is required. This study reviewed, analyzed and assessed successful priority setting techniques used by other jurisdictions. It proposed an approach for setting ambient air quality objective priorities that integrates the concerns of stakeholders with Alberta Environment requirements. A literature and expert review were used to examine existing priority-setting techniques used by other jurisdictions. An analysis process was developed to identify the strengths and weaknesses of various techniques and their ability to take into account the complete pathway between chemical emissions and damage to human health or the environment. The key strengths and weaknesses of each technique were identified. Based on the analysis, the most promising technique was the tool for the reduction and assessment of chemical and other environmental impacts (TRACI). Several considerations for using TRACI to help set priorities for ambient air quality objectives were also presented. 26 refs, 8 tabs., 4 appendices

  12. Automated Processing Workflow for Ambient Seismic Recordings

    2017-12-01

    Structural imaging using body-wave energy present in ambient seismic data remains a challenging task, largely because these wave modes are commonly much weaker than surface wave energy. In a number of situations body-wave energy has been extracted successfully; however, (nearly) all successful body-wave extraction and imaging approaches have focused on cross-correlation processing. While this is useful for interferometric purposes, it can also lead to the inclusion of unwanted noise events that dominate the resulting stack, leaving body-wave energy overpowered by the coherent noise. Conversely, wave-equation imaging can be applied directly on non-correlated ambient data that has been preprocessed to mitigate unwanted energy (i.e., surface waves, burst-like and electromechanical noise) to enhance body-wave arrivals. Following this approach, though, requires a significant preprocessing effort on often Terabytes of ambient seismic data, which is expensive and requires automation to be a feasible approach. In this work we outline an automated processing workflow designed to optimize body wave energy from an ambient seismic data set acquired on a large-N array at a mine site near Lalor Lake, Manitoba, Canada. We show that processing ambient seismic data in the recording domain, rather than the cross-correlation domain, allows us to mitigate energy that is inappropriate for body-wave imaging. We first develop a method for window selection that automatically identifies and removes data contaminated by coherent high-energy bursts. We then apply time- and frequency-domain debursting techniques to mitigate the effects of remaining strong amplitude and/or monochromatic energy without severely degrading the overall waveforms. After each processing step we implement a QC check to investigate improvements in the convergence rates - and the emergence of reflection events - in the cross-correlation plus stack waveforms over hour-long windows. Overall, the QC analyses suggest that

    Tremblay, Jose-Philippe

    Les systemes avioniques ne cessent d'evoluer depuis l'apparition des technologies numeriques au tournant des annees 60. Apres le passage par plusieurs paradigmes de developpement, ces systemes suivent maintenant l'approche " Integrated Modular Avionics " (IMA) depuis le debut des annees 2000. Contrairement aux methodes anterieures, cette approche est basee sur une conception modulaire, un partage de ressources generiques entre plusieurs systemes et l'utilisation plus poussee de bus multiplexes. La plupart des concepts utilises par l'architecture IMA, bien que deja connus dans le domaine de l'informatique distribuee, constituent un changement marque par rapport aux modeles anterieurs dans le monde avionique. Ceux-ci viennent s'ajouter aux contraintes importantes de l'avionique classique telles que le determinisme, le temps reel, la certification et les cibles elevees de fiabilite. L'adoption de l'approche IMA a declenche une revision de plusieurs aspects de la conception, de la certification et de l'implementation d'un systeme IMA afin d'en tirer profit. Cette revision, ralentie par les contraintes avioniques, est toujours en cours, et offre encore l'opportunite de developpement de nouveaux outils, methodes et modeles a tous les niveaux du processus d'implementation d?un systeme IMA. Dans un contexte de proposition et de validation d'une nouvelle architecture IMA pour un reseau generique de capteurs a bord d?un avion, nous avons identifie quelques aspects des differentes approches traditionnelles pour la realisation de ce type d?architecture pouvant etre ameliores.

    Lorenzo G. Mantovani

    2003-03-01

    Full Text Available This article represents the first evaluation that compares the economic consequences of managing postsurgical pain with tramadol or ketorolac in the Italian setting. The economic evaluation was based on 5 clinical trials that directly compared the efficacy and tolerability of tramadol and ketorolac treatments in different settings and that contained drug consumption data. Since the review of these data confirmed that their efficacy is comparable (tramadol showed a quicker onset of the analgesic action, which was not considered for the purposes of the economic evaluation, it was chosen to conduct a cost minimization analysis. The calculations were made considering two different drug acquisition costs: the hypothetical price for the hospital, computed by discounting 50% off the retail price, and the mean price really paid by hospitals according to the IHS. The analyses showed that, when the discounted price is applied, tramadol induces costs that are similar to those induced by ketorolac in 2/3 of the cases and lower in the remaining 1/3. Considering the mean price paid by hospitals, tramadol results economically more advantageous than ketorolac in all considered settings. In conclusion, ketorolac and tramadol are two effective and tolerable drugs in the management of post-surgical pain, although they differ in the adverse event pattern and in the rapidity of their action. In the Italian setting, tramadol appears to be economically more efficient, due to lesser consumption and lower drug acquisition costs.

    Today, the European Union (EU) nuclear panorama is changing rapidly. Many Member States have reconsidered the nuclear energy option and its contribution towards a balanced energy mix. Such perspectives fit well with the European 2020 Strategy for smart, sustainable and inclusive growth which aims at a 'Resource efficient Europe'. This objective demands a gradual but clear shift towards a low-carbon economy. In fact today, nuclear power already contributes to 2/3 of the low-carbon electricity production. It is unquestionably our shared duty to ensure that nuclear energy be used in a responsible manner. Nuclear safety is, and remains, an absolute priority for the EU. This includes the highest safety standards for the design, for the operation and for the security of nuclear installations. But, it also extends to the safe management of spent fuel and radioactive waste, generated in all Member States, regardless of whether they have nuclear power plants or not. Nuclear techniques are also to be found in the medical sector, for cancer therapy, and in industry, in such applications as the quality control of welds. The draft of the European directive on radioactive wastes imposes that all radioactive waste should be disposed in the member state that has produced it except in case of agreements between member states. This directive does not apply to military wastes, to ore tailings and authorized radioactive releases

    organizations of that sector, alongside regular manufacturing operations, seems to contribute to their performance. In fact, most of these organizations currently are industry leaders worldwide. The data that form the basis of this research were obtained through 65 semi-structured interviews with representatives of project management, HRM and upper management in eight organizations in the aerospace industry in Quebec. First, the collected data was treated case by case using the qualitative data analysis software application Atlas.ti. Subsequently, the description and interpretation of the data were developed in a transversal way to achieve a sector-wide portrait of the HRM of PMs. The results reveal that PMs, like other human resources, do present particular HRM challenges and are actually managed as such in the organizations. PMs benefit both from traditional HRM practices (collective HRM) and from the relationship established and maintained with their immediate manager (individualized HRM). A network of actors is also involved in the HRM of PMs. Among these, the immediate manager of PMs stands out as the key HRM actor. In addition to applying HRM policies and practices to PMs, the manager of PMs, in his position of proximity with PMs, is destined to play different roles such as coach, motivator and talent agent. This hybrid HRM of PMs provides a sense of well-being among PMs and allows organizations to retain these creators of value, it secures faithful customers (repeat business) as a consequence of the success of projects managed by those PMs, and contributes to build a pool for their future managerial elite. Keywords: project management, human resource management, project manager, proximity management, high technology, aerospace industry, Quebec.

    Full Text Available The concept of common good could be declined in three major points: 1 the theft of the good itself from the profit mindset; 2 the creation of a link between the community and the good; 3 the creation of a new management form, neither public nor private, which knows the capacity of the good itself. From the analysis of the schedule published by MiBAC, it is clear that there is a lack of founds addressed to the artistic research. The situation that occurs nowadays is imposing the necessity of identifying another kind of development model. I took, as a research topic, Teatro Valle, which is one of the most important case in the Italian national context. The management of the entire structure undergoes through the principles of non-rivalry, non-exclusion and self-governance. The strongest points of this model are: the idea of an alternative management and the creation of synergies between several cultural movements.The theatre itself has been seeing as a multi-functional location: there are lots of performances flanked by debates, conferences, talks, and other initiatives. Another important aspect is the great visibility that the experience has been receiving through the years. However it is necessary to underline that the building, which is a private property, lives in a condition of lawlessness because it has been occupied. Moreover Teatro Valle has been accused of unfair competition by other cultural spaces. Since the culture is the common thread that helps us to uphold our identity, the common goods help us to recognize ourselves and state our fundamental rights.

  11. Seismic and Biological Sources of Ambient Ocean Sound

    Science.gov (United States)

    Freeman, Simon Eric

    Sound is the most efficient radiation in the ocean. Sounds of seismic and biological origin contain information regarding the underlying processes that created them. A single hydrophone records summary time-frequency information from the volume within acoustic range. Beamforming using a hydrophone array additionally produces azimuthal estimates of sound sources. A two-dimensional array and acoustic focusing produce an unambiguous two-dimensional `image' of sources. This dissertation describes the application of these techniques in three cases. The first utilizes hydrophone arrays to investigate T-phases (water-borne seismic waves) in the Philippine Sea. Ninety T-phases were recorded over a 12-day period, implying a greater number of seismic events occur than are detected by terrestrial seismic monitoring in the region. Observation of an azimuthally migrating T-phase suggests that reverberation of such sounds from bathymetric features can occur over megameter scales. In the second case, single hydrophone recordings from coral reefs in the Line Islands archipelago reveal that local ambient reef sound is spectrally similar to sounds produced by small, hard-shelled benthic invertebrates in captivity. Time-lapse photography of the reef reveals an increase in benthic invertebrate activity at sundown, consistent with an increase in sound level. The dominant acoustic phenomenon on these reefs may thus originate from the interaction between a large number of small invertebrates and the substrate. Such sounds could be used to take census of hard-shelled benthic invertebrates that are otherwise extremely difficult to survey. A two-dimensional `map' of sound production over a coral reef in the Hawaiian Islands was obtained using two-dimensional hydrophone array in the third case. Heterogeneously distributed bio-acoustic sources were generally co-located with rocky reef areas. Acoustically dominant snapping shrimp were largely restricted to one location within the area surveyed

    Full Text Available O presente trabalho intitulado “MODIFICANDO O AMBIENTE ESCOLAR ATRAVÉS DO PROJETO MEIO AMBIENTE: CULTIVANDO E CONHECENDO AS PLANTAS” tem como desígnio apresentar o desenvolvimento do projeto “meio ambiente: cultivando e conhecendo as plantas”, no qual teve como proposta sensibilizar os alunos sobre a importância e preservação do meio ambiente através da prática e modificação do ambiente escolar, onde procurou-se utilizar materiais reciclados, tais como, garrafas pet, pneus velhos, carreteis de fios de eletricidade, e também mudas de arvore, plantas e hortaliças. Desta forma buscou se utilizar da criatividade dos envolvidos no processo para a transformação do ambiente escolar seco e vazio, para uma ambiente alegre, e acolhedor. O projeto foi elaborado pelas professoras da Extensão Betel, e aplicado em parceria com acadêmicos do sexto semestre do curso de Licenciatura em Pedagogia da Universidade do Estado do Mato Grosso (UNEMAT, campus de Sinop. Tendo como proposta a interdisciplinaridade, o projeto foi divido em três eixos orientados pelas professoras Edneuza Alves Trugillo, Sinóvia Rauber e Mariza Kreinner, abrangendo assim alunos e professoras de duas turmas de 2º Ano do Ensino Fundamental, e acadêmicos e professores da Universidade, os eixos foram arborização, jardinagem e horta, onde teve a duração de aproximadamente dois meses. A finalização das práticas obteve resultados satisfatórios e objetivos alcançados, tanto pela sensibilização dos alunos sobre a preservação e importância do meio-ambiente, quanto pela prática de intervenção pelos acadêmicos envolvidos no processo, que em coletividade conseguiram modificar o ambiente escolar através do objetivo do projeto, meio-ambiente, proporcionando assim um enriquecimento na formação acadêmica enquanto práticas pedagógicas.

    Swarm robotics is one of the fastest growing areas of modern technology. Being subclass of multi-agent systems it inherits the main part of scientific-methodological apparatus of construction and functioning of practically useful complexes, which consist of rather autonomous independent agents. Ambient light sensors (ALS) are widely used in robotics. But speaking about swarm robotics, the technology which has great number of specific features and is developing, we can't help mentioning that its important to use sensors on each robot not only in order to help it to get directionally oriented, but also to follow light emitted by robot-chief or to help to find the goal easier. Key words: ambient light sensor, swarm system, multiagent system, robotic system, robotic complexes, simulation modelling

  5. Alberta ambient air quality objectives : sulphur dioxide

    International Nuclear Information System (INIS)

    2011-02-01

    Sulphur dioxide (SO 2 ) is a colourless, non-flammable gas with a pungent odour. Exposure to SO 2 can result in numerous effects to the pulmonary system. This paper outlined current Alberta ambient air quality objectives in relation to SO 2 . The 1-hour average Alberta ambient air quality objective for SO 2 is currently 450 μg per m 3 . Studies conducted with healthy humans showed increased airway resistance and bronchoconstriction, as well as decreased maximum expiratory flow. Exercise can increase the severity of response to SO 2 in healthy and asthmatic individuals. Long-term exposure to SO 2 levels can also impact the metabolic activity of vegetation. The United States Environmental Protection Agency (EPA) recently announced their intention to reduce the 1-hour SO 2 standard to between 131 to 262 μg per m 3 . 7 refs.

    Full Text Available En Afrique du Nord, de nombreux aquifères sont surexploités, principalement du fait d’une agriculture irriguée intensive. Cependant, les politiques publiques qui ont cherché à réguler cet usage se sont montrées jusqu’à maintenant peu efficaces, du fait du manque de moyens et parce que les agriculteurs les considèrent comme peu légitimes. L’article analyse un cas de gestion collective de l’usage des eaux souterraines par les agriculteurs eux-mêmes, dans le cadre d’une association au Sud de la Tunisie. Dans la zone de Bsissi Oued El Akarit, l’administration multipliait dans les années 1990 les procédures de contrôle des puits, conduisant à de nombreux conflits. En 1999, les agriculteurs et l’administration se sont mis d’accord pour qu’un groupement de développement agricole soit créé spécifiquement pour contrôler les puits et forages dans cette zone. Depuis, le groupement a effectivement réussi à mettre en oeuvre un tel contrôle, mais reste toujours fragile financièrement car il ne s’auto-finance pas. Le processus de concertation qui a conduit à ce dispositif de gestion a réussi grâce à : i la posture de l’administration, à la fois ferme en matière d’application des lois en vigueurs, et ouverte à la concertation avec les agriculteurs, et ii aux compétences et à la légitimité des leaders du groupement. Cette expérience montre que, dans certains cas, les agriculteurs peuvent devenir partie prenante d’une cogestion des eaux souterraines pour un usage durable de cette ressource.

Entre outros pontos de discussão, argumenta que o cientificismo contribuiu para que se aprofundasse a visão de posse absoluta e exploração implacável sobre a natureza (terra, água, florestas, e que as fragilidades apresentadas pelo Planeta na atualidade são resultados do modo pelo qual se deu essa relação, ou seja, o modo como a partir do "domínio" sobre a natureza, o homem dilapidou e continua dilapidando os recursos naturais, com o intuito de produzir cada vez mais bens para o consumo, gerar e concentrar riquezas. Por fim, o artigo trata da emergência da educação ambiental e da prática interdisciplinar entre saberes, para que se possa construir uma nova ética ambiental, tão necessária à sobrevivência do Planeta.

    1981-08-01

    This research is an analysis of various measures of ambient air pollution useful in cross-sectional epidemiological investigations and rick assessments. The Chestnut Ridge area health effects investigation, which includes a cross-sectional study of respiratory symptoms in young children, is used as a case study. Four large coal-fired electric generating power plants are the dominant pollution sources in this area of western Pennsylvania. The air pollution data base includes four years of sulfur dioxide and five years of total suspended particulate concentrations at seventeen monitors. Some 70 different characterizations of pollution are constructed and tested. These include pollutant concentrations at various percentiles and averaging times, exceedence measures which show the amount of time a specified threshold concentration is exceeded, and several dosage measures which transform non-linear dose-response relationships onto pollutant concentrations.

  17. The interaction of supernova ejecta with an ambient medium

    International Nuclear Information System (INIS)

    Chevalier, R.A.

    1983-01-01

    Plausible environments for supernovae are the interstellar medium with constant density or a circumstellar medium built up by mass loss with rho proportional to r -2 . Self-similar solutions for the interaction region between the expanding supernova gas and the ambient gas exist provided that the expanding gas has rho proportional to rsup(-n) with n > 5. The circumstellar medium case is likely to be important for the early evolution of Type II supernovae because their progenitor stars are probably red supergiants. The radio and X-ray emission observed from extragalactic supernovae may be from this interaction region. The early self-similar solutions can also be applied to the young galactic remnants. (Auth.)

  18. Surface Properties of Metal Hydroxide Microparticles in the Ambient Air

    Directory of Open Access Journals (Sweden)

    Zakharenko Valery

    2017-01-01

    Full Text Available The adsorption and photoadsorption properties of Mg(OH2 and Ca(OH2 microparticles in the ambient air were investigated. The compositional analysis of an adsorption layer of microparticles was carried out. The kinetics of photodesorption of molecules from microcrystal surfaces and the interaction of HCFC-22 (CHF2Cl in the dark and under light were studied. Quantum yields and their spectral dependencies were determined for CO2 photodesorption, O2 and CO photoadsorption. The effect of weakly bound CO displacement from the surface of microparticles was revealed during dark adsorption of HCFC-22. It is supposed that adsorbed CO is formed as a result of atmospheric CO2 reduction after the break of Mg—OH bonds. In case of calcium hydroxide, CO is generated during the interaction of calcium hydroxide with carbon dioxide in the presence of water.

  19. MHD modeling for Formation Process of Coronal Mass Ejections: Interaction between Ejecting Flux Rope and Ambient Field

    Science.gov (United States)

    Shiota, Daikou; Kusano, Kanya; Miyoshi, Takahiro; Shibata, Kazunari

    Coronal mass ejections (CMEs), in which large amount of magnetic flux is launched into the interplanetary space, are most explosive phenomena in the solar corona. Due to their large influences to the space environment near the Earth, it is very important to make cleat how CMEs are formed and how determine the field orientations within CMEs. In order to examine the sufficient conditions, we performed three dimensional magnetohydrodynamic simulation of formation processes of CMEs, focusing on interaction (reconnection) between an ejecting flux rope and its ambient field. We examined three cases with different ambient fields: no ambient field, and cases with dipole field of two opposite directions which are parallel and anti-parallel to that of the flux rope surface. As the results, while the flux rope disappears in the anti-parallel case, in other cases the flux ropes can evolve to CMEs and however shows different amount of rotation of the flux rope. The results mean that the interaction between an ejecting flux rope and its ambient field is a significant process for determining CME formation and CME orientation, and also show that the amount and direction of magnetic flux within the flux rope and the ambient field are key parameters for CME formation. Especially, the interaction (reconnection) plays a significant role to the rotation of the flux rope, with a process similar to "tilting instability" in a spheromak-type experiment of laboratory plasma.
