    The chemical substances that are used in the hospitals, and their remainders, represent risks for the environment, the health and security of those who work in these establishments, and of the civil population. The deficiency of a norm that establishes the directives for the handling responsible for such products in the hospitals that our country has motivated the elaboration of a technical scheme that serves as it guides for the correct manipulation, storage and safe disposition of chemical substances in the twenty-nine hospitals of the Caja Costarricense del Seguro Social, establishing Procedures of Standard Operation for its management. To development of the guideline proposal it took a sample of hospitals that includes three levels of comple complexity: national, regional and peripheral. Applying a methodology of evaluation of risks two factors of risk of hospitable were determined, the zones and the population but affected by the existence of chemical substances, which allowed to identify some operative deficiencies in the product handling diverse. The qualitative analysis of the results lead to the elaboration of a technical scheme that includes an instrument for the identification of risks, guideline for the management responsible for hospitable chemical substances, a friendly tool computations like complementary source of intelligence and the proposal of a governing group in charge of the monitoring of the fulfillment of these lineament.

    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.

    Ambient echolalia is a rare condition with few reported cases. We report the case of a 20-year-old man with a germinoma around the bilateral ventriculus lateralis who exhibited ambient echolalia. Clinical features included instinctive grasp reaction and compulsive manipulation of tools in his right hand. Speech or mental deterioration has been cited as a cause of ambient echolalia, but neither dementia nor aphasia was present. We propose that ambient echolalia in our case could be interpreted as a disinhibition of pre-existing essentially intact motor subroutines due to damage of the medial frontal lobe.

Attraverso lo studio delle politiche di tutela, delle esperienze amministrative e della prassi di governo del patrimonio storico, dal primo dopoguerra agli anni Settanta, si può cercare di comprendere quali sono i presupposti che hanno portato a collocare il tema della tutela entro quella nuova cultura della città, sorta in ambito al dibattito urbanistico nazionale e che ha assunto il tema specialistico della tutela come campo di sperimentazione per la ridefinizione delle più ampie strategie di amministrazione della città, con progetti finalizzati alla conservazione del tessuto urbano storico nella sua globalità. Con il Piano per il centro storico di Bologna del 1969 e il successivo Peep del 1973, nonché con le vicende amministrative che ne hanno accompagnato l’attuazione e la gestione per più di venti anni, il centro storico diventa al contempo un campo di sperimentazione di politiche urbanistiche, politiche sociali e politiche di tutela del patrimonio storico. Nel mirare ad una tutela multidimensionale dei tessuti storici, i programmi elaborati dalle pubbliche amministrazioni hanno comportato la necessità di spostare il fuoco del progetto urbanistico per i tessuti storici verso una difficile integrazione tra istanze di conservazione dell’ambiente costruito, dei suoi manufatti e dello spazio collettivo, ed esigenze di governo complessivo delle dinamiche di trasformazione ed uso della città. The debate on urban renewal of historical city centers continues to propose new arguments, connected to the difficulties carried on by new uses demands, that carry on an equal variety of technical instruments and political options.

    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.

    To examine the association of hourly time lagged concentration of ambient particulate matter and death due to stroke. Mortality data for five years (January 1990 to December 1994) were obtained from the Ministry of Health, Labour, and Welfare of Japan. Data were used only if the deceased was 65 years old or older at the time of death, if death was attributed to intracerebral haemorrhage or ischaemic stroke, and if the deceased lived in one of 13 major urban areas. Hourly mean concentrations of PM7, NO2, and photochemical oxidants were measured at monitoring stations in the 13 areas. Time stratified case-crossover analysis was used to examine the data for evidence of triggering stroke mortality. The 1-hour mean concentration of PM7 measured about 2 hours before death was associated with the risk of death due to intracerebral haemorrhage from April to September (odds ratio = 2.40, 95% CI 1.48 to 3.89, for exposure to PM7 of more than 200 microg/m3 (threshold)). The higher risk was independent of the 24-hour mean concentration of PM7. PM7 was not associated with death due to ischaemic stroke. Transiently high concentrations of PM7 are associated with death due to intracerebral haemorrhage. Air quality standards or guidelines for particulate matter should be based not only on 24-hour mean concentrations, but also on hourly data.

    2007-01-01

    Actual thermal efficiency, electric-power output, fuel-air ratio and specific fuel consumption (SFC) vary according to the ambient conditions. The amount of these variations greatly affects those parameters as well as the plant incomes. In this paper the effect of ambient temperature as a seasonal variation on a gas power plant has been numerically studied. For this purpose, the gas turbine model and different climate seasonal variations of Ray in Iran are considered in this study. For the model, by using average monthly temperature data of the region, the different effective parameters were compared to those in standard design conditions. The results show that ambient temperature increase will decrease thermal efficiency, electric-power out put and fuel-air ratio of the gas turbine plant whereas increases the specific fuel consumption

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

    International Nuclear Information System (INIS)

    Al-Zeyoudi, Hend; Sasmito, Agus P.; Shamim, Tariq

    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.

Within the scope of a Canadian refurbishment project of a CANDU 6 (NPP) put in service in 1983, structures and equipment must sustain a new seismic demand characterised by the uniform hazard spectrum (UHS) obtained from a site specific study defined for a return period of 1/10,000 years. This UHS exhibits larger spectral ordinates in the high-frequency range than those used in design. To reduce modeling uncertainties as part of a seismic probabilistic safety assessment (PSA), Hydro-Québec developed a procedure using ambient vibrations testing to calibrate a detailed 3D finite element model (FEM) of the containment and reactor building (RB). This calibrated FE model is then used for generating floor response spectra (FRS) based on ground motion time histories compatible with the UHS. Seismic fragility analyses of the reactor building (RB) and structural components are also performed in the context of a case study. Because the RB is founded on a large circular raft, it is possible to consider the effect of the seismic wave incoherency to filter out the high-frequency content, mainly above 10 Hz, using the incoherency transfer function (ITF) method. This allows reducing significantly the non-necessary conservatism in resulting FRS, an important issue for an existing NPP. The proposed case study, and related methodology using ambient vibration testing, is particularly useful to engineers involved in seismic re-evaluation of

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.

    Full Text Available In this work, volatile organic compounds (VOCs in the ambient air of a secondary fiber paper mill were analyzed. For the sake of studying pollution comprehensively, four sites in the paper mill were analyzed and active sampling methods were used. Desorption was carried out with two solvents, carbon disulfide and dichloromethane. The compositions of VOCs were determined by gas chromatography-mass spectrometry (GC-MS method. The main identified substances in the four sites were as follows: (1 waste paper sorting room: alkanes, phenols, and esters; (2 papermaking workshop: benzene series, alkanes, ethers, and phenols; (3 vacuum pump outlet: benzene series and phenols; and (4 office area: benzene series and phenols. Two main toxic substances in VOCs, the benzene series and phenols, were detected in the ambient air of the paper mill. The benzene series existed in three places along the main process of the paper mill and even existed in the office area, which was far away from the production line. Additionally, phenols were detected in all sampling locations in the paper mill.

    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.

    Diesel exhaust contains large numbers of ultrafine particles (UFPs, <0.1µm) and is a recognized human carcinogen. However, epidemiological studies have yet to evaluate the relationship between UFPs and cancer incidence. We conducted a case-control study of UFPs and incident prostate cancer in Montreal, Canada. Cases were identified from all main Francophone hospitals in the Montreal area between 2005 and 2009. Population controls were identified from provincial electoral lists of French Montreal residents and frequency-matched to cases using 5-year age groups. UFP exposures were estimated using a land use regression model. Exposures were assigned to residential locations at the time of diagnosis/recruitment as well as approximately 10-years earlier to consider potential latency between exposure and disease onset. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated per interquartile range (IQR) increase in UFPs (approximately 4000 particles/cm 3 ) using logistic regression models adjusting for individual-level and ecological covariates. Ambient UFP concentrations were associated with an increased risk of prostate cancer (OR=1.10, 95% CI: 1.01, 1.19) in fully adjusted models when exposures were assigned to residences 10-years prior to diagnosis. This risk estimate increased slightly (OR=1.17, 95% CI; 1.01, 1.35) when modeled as a non-linear natural spline function. A smaller increased risk (OR=1.04, 95% CI: 0.97, 1.11) was observed when exposures were assigned to residences at the time of diagnosis. Exposure to ambient UFPs may increase the risk of prostate cancer. Future studies are needed to replicate this finding as this is the first study to evaluate this relationship.

    We report the case of a 69-year-old woman with cerebral infarction in the left anterior cingulate cortex and corpus callosum. She showed hyperlexia, which was a distinctive reading phenomenon, as well as ambient echolalia. Clinical features also included complex disorders such as visual groping, compulsive manipulation of tools, and callosal disconnection syndrome. She read words written on the cover of a book and repeated words emanating from unrelated conversations around her or from hospital announcements. The combination of these two features due to a focal lesion has never been reported previously. The supplementary motor area may control the execution of established subroutines according to external and internal inputs. Hyperlexia as well as the compulsive manipulation of tools could be interpreted as faulty inhibition of preexisting essentially intact motor subroutines by damage to the anterior cingulate cortex reciprocally interconnected with the supplementary motor area.

    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

    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.

    2008-01-01

    One of the most troubling symptoms of Alzheimer's disease is the loss of the patient's sense of identity. This loss complicates relationships, increases apathy, and generally impedes quality of life for the patient. We describe a novel in-home ambient display called Biography Theatre that cycles through music, photographs, movies, and narratives drawn from the patient's past and current life. We conducted an exploratory case study with an 84-year-old male with moderate-stage Alzheimer's disease (Mr H). The study consisted of three phases: a baseline phase, a phase wherein autobiographical materials were collected and discussed, and a phase wherein the display was deployed in the home. The patient demonstrated improvement on standardised tests of apathy and positive self-identity, but did not improve on tests of autobiographical memory, anxiety, depression, and general cognition. We also report on caregiver reactions to the intervention and how the display helped them cope with and reinterpret their loved one's condition. This work suggests that interdisciplinary work involving "off the desktop" computing technologies may be a fruitful way to provide rehabilitative benefit for individuals with Alzheimer's disease.

    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.

    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.

  14. Ambient Dried Aerogels

    Science.gov (United States)

    Jones, Steven M.; Paik, Jong-Ah

    2013-01-01

    A method has been developed for creating aerogel using normal pressure and ambient temperatures. All spacecraft, satellites, and landers require the use of thermal insulation due to the extreme environments encountered in space and on extraterrestrial bodies. Ambient dried aerogels introduce the possibility of using aerogel as thermal insulation in a wide variety of instances where supercritically dried aerogels cannot be used. More specifically, thermoelectric devices can use ambient dried aerogel, where the advantages are in situ production using the cast-in ability of an aerogel. Previously, aerogels required supercritical conditions (high temperature and high pressure) to be dried. Ambient dried aerogels can be dried at room temperature and pressure. This allows many materials, such as plastics and certain metal alloys that cannot survive supercritical conditions, to be directly immersed in liquid aerogel precursor and then encapsulated in the final, dried aerogel. Additionally, the metalized Mylar films that could not survive the previous methods of making aerogels can survive the ambient drying technique, thus making multilayer insulation (MLI) materials possible. This results in lighter insulation material as well. Because this innovation does not require high-temperature or high-pressure drying, ambient dried aerogels are much less expensive to produce. The equipment needed to conduct supercritical drying costs many tens of thousands of dollars, and has associated running expenses for power, pressurized gasses, and maintenance. The ambient drying process also expands the size of the pieces of aerogel that can be made because a high-temperature, high-pressure system typically has internal dimensions of up to 30 cm in diameter and 60 cm in height. In the case of this innovation, the only limitation on the size of the aerogels produced would be in the ability of the solvent in the wet gel to escape from the gel network.

    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.

    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.

    Rodriguez, Daniel A.; Huegy, Joseph; Gibson, Jacqueline MacDonald

    2014-01-01

    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. Further, 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. PMID:25490890

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

    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.

La mancanza di esemplari con fenotipi intermedi tra L. corsicanus e L. europaeus e l?assenza di introgressione di aplotipi mitocondriali tra le due specie, portano ad escludere il rischio di ibridazione. L?esercizio venatorio può rappresentare un reale fattore limitante per le popolazioni di L. corsicanus (benché la specie non sia legalmente cacciabile a causa delle difficoltà di discriminazione sul campo con L. europaeus (cacciabile.

    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

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?

    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. The paper especially focuses on algorithms and methods that can be utilized to realize modern mobile ambient systems.

    2002-08-01

    Full Text Available Maroc a toujours fait du développent du secteur de l'eau une priorité et un choix stratégique. Ce secteur qui constitue un des principaux leviers du développement économique et social, se trouve confronté a deux défis essentiels: - L'épuisement des ressources en eau en rapport avec l'accroissement de la demande en eau tous usages confondus, avec une tendance a la pénurie absolue d'ici 2025. - La dégradation des ressources en eau qui subissent différentes formes de pollution. La rareté des ressources en eau, et la forte irrégularité aussi bien spatiale, que temporelle, qui caractérisent le contexte marocain, ont conditionné les choix des pouvoirs publics 2 adopter une stratégie globale dont les résultats ont prouvé son efficacité particulikrement durant les périodes de sécheresse consécutives. Cette stratégie tout azimuts a concerné aussi bien le plan législatif et réglementaire, que le plan de la mobilisation et de la protection des ressources en eau. Les études de pldcation entreprises ont montré que les ressources en eau conventionnelles seront saturées au niveau de la majorité de bassins a l'horizon 2020, et que ces déficits prévus risquent d'gtre aggravés dans le cas de conjonction avec des périodes de sécheresse. La politique de mobilisation et de protection des ressources en eau, en particulier souterraine dont le potentiel mobilisable est de l'ordre de 4 milliards de m3 sur un total de 20 milliards, nécessite une gestion participative ainsi que le recours a de nouvelles approches et technologies pour compléter les méthodes conventionnelles utilisées jusqu'a présent.Marruecos siempre ha considerado prioritario y estratégico el desarrollo del sector del agua.

    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.

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

    Science.gov (United States)

    Vallianatos, Filippos; Koutalonis, Ioannis; Moisidi, Margarita; Chatzopoulos, Georgios

    2018-05-01

    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.

  18. Ambient oxygen promotes tumorigenesis.

    Directory of Open Access Journals (Sweden)

    Ho Joong Sung

    2011-05-01

    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.

    2014-01-01

    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. PMID:24982994

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.

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

    Directory of Open Access Journals (Sweden)

    Leonardo Naldini

    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.

    Ambient ionization mass spectrometry emerged as a new scientific discipline only about ten years ago. A considerable body of information has been reported since that time. Keeping the sensitivity, performance and informativity of classical mass spectrometry methods, the new approach made it possible to eliminate laborious sample preparation procedures and triggered the development of miniaturized instruments to work directly in the field. The review concerns the theoretical foundations and design of ambient ionization methods. Their advantages and drawbacks, as well as prospects for application in chemistry, biology, medicine, environmetal analysis, etc., are discussed. The bibliography includes 194 references

  12. 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

    Full Text Available Clean air is the basic requirement of all living organisms. 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

    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

    réalité, il importe qu’un partenariat soit établi entre les différents acteurs liés à la gestion de la vallée du Sitatunga en particulier et des milieux humides en général : les ONG, l’État et les communautés locales.Bénin, a country in West Africa is actually facing the destruction of its wetlands, especially those in the southern part of the country. The wetlands which their richness in natural resources are important for both human and wildlife are also threatened by many factors. The most important threat is population pressure. Although recognised as Ramsar sites, the destruction continues. In 1995, the Government has decided to create community protected areas in this part of the country. The objective of this research is to understand the main challenges around the community management of wetlands. The case of the Sitatunga valley, in south Bénin has been studied. The methodology used consisted on interviews with stakeholders during a period of 3 months. The results show that, although the good intentions of community management, its practical application is not easy, and reveal many difficulties in its practical application. The site although rich in biodiversity and used as refuge for several species, is regarded as useless even harmful by the bordering populations, which are more worried by their poverty state. The traditions and values formerly allotted to the wetlands almost disappeared and individualism is growing. It is important to take into account all these factors to truly hope to preserve these wetlands. The study shows that management of the wetlands on a Beninese scale is also difficult. Indeed, the government through its structures struggles to coordinate its activities. It is the same for NGOs. The situation is accentuated by the poor relations between NGOs and government institutions which consider each other more as adversaries than as partners. This affects the effectiveness of the undertaken activities. It is then

    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.

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.

    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.

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.

  16. 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 Comment définir et analyser sociologiquement la gestion ? C’est à cette interrogation que cet article propose des réponses. Dans cette perspective, les auteurs rappellent que la plupart des activités sociales sont dorénavant concernées par des dispositifs de gestion ou, à tout le moins, par des raisonnements qui empruntent à cette discipline. Aussi, en rendre compte avec les catégories de la sociologie, dans une visée de connaissance, et non d’aide à l’action gestionnaire, constitue-t-il un objectif légitime. C’est pourquoi, les auteurs construisent un programme détaillé de recherche, en trois axes, tenant compte aussi bien des acteurs, des visées, que des principes et dispositifs. Ils y voient un moyen d’apprécier les dynamiques à l’œuvre dans la gestionnarisation de la société et, peut-être, d’envisager des conceptions alternatives.The sociological definition and analysis of management is the authors concern. They recall how most social activities have now become management issues or at least coloured by them. Establishing this fact from a sociological angle, independently of concrete concerns, is a legitimate contribution to knowledge. Hence three programmatic research axes are proposed taking into account the actors, their goals, principles as well as ways and means. What is going forward in the managerialization of society can thus be exposed and alternatives eventually envisaged.

    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.

  4. Types for BioAmbients

    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.

    SWM (Solid Waste Management) systems have always been compatible with the societal need at every point of time. In 1950's it was oriented towards maintaining public health standards mainly to control infectious diseases. While in 1970's energy generation was considered as the vital aspect of the system. In 1990's reduction in waste generation and recycling were officially incorporated in the waste management regulation. By enacting basic law in 2000 A.D.; the society is poised to become a recycling based society in its drive towards sustainable society. The document explain the actual solid waste strategic management, and related issues, in Japan. [Italian] Nel corso della storia la gestione dei rifiuti solidi si e sempre resa compatibile con le esigenze della societa espresse in quel determinato momento. Negli anni '50 la gestione era orientata al mantenimento di determinati standard di salute pubblica, principalmente rivolti al controllo della diffusione di malattie infettive, mentre negli anni '70 la produzione di energia dai rifiuti era considerato l'aspetto prioritario per la corretta risoluzione del problema gestionale dei rifiuti. Negli anni '90 la riduzione della produzione dei rifiuti e il loro riciclaggio sono stati inseriti, come principio, nei documenti per la regolamentazione della gestione dei rifiuti solidi. Con l'approvazione di specifiche normative quadro, a partire dai primi anni del 2000, la societa si avvia ad essere una societa basata sul riciclaggio, nel suo cammino verso la sostenibilita. Nel testo si esaminano i principali aspetti strategici della gestione dei rifiuti solidi, e problematiche annesse, in Giappone.

    2011-11-01

    Questo articolo intende dunque svolgere una riflessione critica sulla opportunità di indirizzarsi verso una gestione di tipo “multi-scala”, che comprenda sia un livello organizzativo “micro” sia un livello organizzativo “meso”. L'effettiva capacità di funzionamento del modello “multi-scala” deriverà dalla capacità di rendere armonici e sinergici tra di loro tali due livelli organizzativi. Today, the management model adopted for Italian cultural organizations and Italian cultural heritage derives from the new public management theory, that has been designed, crafted and firstly implemented in Anglophone countries. Instead, the management model should be consistent with the features of the cultural heritage of the specific country. In the Italian case, that is a widespread cultural heritage, strongly linked with the history of the territory. Hence, this article aims at analyzing the opportunity of developing a “multi-scale” management approach, able to combine the traditional “micro” organizational perspective, with a “meso” organizational perspective.

    Exergy (availability) is the amount of mechanical work that could be produced by reversible processes. This notion is revisited in the case when ambient temperature fluctuates. Simple examples are first considered, and then a theoretical approach is developed. It results that the most reliable way for combining entropy and total energy into an exergy function is a linear combination where entropy is multiplied by a constant temperature. It results that ambient air has non-zero exergy, but tha...

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.

    Melina Vázquez

    Full Text Available Resumen El trabajo propone explorar las condiciones de posibilidad y los modos en que se produce un ciclo de participación política juvenil en Argentina que encuentra en los espacios político-partidarios uno de sus renovados escenarios. Luego de una profunda crisis de representación política que llevó al activismo juvenil a impugnar la política en relación con sus manifestaciones político-partidarias y estatales, los partidos políticos comenzaron a recrear espacios de militancia juvenil, al mismo tiempo que fueron receptores de nuevos activistas que entran a la política. En este proceso se destaca el peso que cobraron partidos políticos que, además, estuvieron a cargo de gestiones de gobierno a nivel nacional y subnacional. En el artículo se busca analizar qué rasgos, propiedades y características dan forma a una nueva figura de activismo entre los y las jóvenes que forman parte de estas experiencias. Más concretamente, propone analizar cómo se ingresa a la militancia, qué sentidos se construyen sobre la misma y qué relaciones se producen entre el activismo y el trabajo en el Estado en relación con dos partidos que se ocupan de gestiones de gobierno en la Provincia de Santa Fe (de la mano del Partido Socialista y en la Ciudad Autónoma de Buenos Aires (por parte de Propuesta Republicana. Se recupera la sociología francesa del activismo militante para mostrar quiénes son los y las jóvenes activistas que militan en ambos partidos, de qué modos participan dentro de los mismos, así como en las gestiones de gobierno de sus respectivos partidos, y qué significados se construyen en torno a las articulaciones y desplazamientos entre las carreras militantes y laborales de las y los activistas. El enfoque que sigue el trabajo permite pensar elementos comunes en relación con los activismos juveniles en partidos en/de gestión más allá de las diferencias político-ideológicas que los caracterizan.

Cet article a pour objectif de proposer une analyse générale dans quatre pays ayant établi des parcs nationaux de manière très précoce, souvent en opposition avec les populations locales ou autochtones. Depuis les années 1970, la participation publique est devenue une pratique commune dans la gestion des parcs nationaux, même si elle revêt des réalités très variables. 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.

    Full Text Available ItSotto la spinta dei cambiamenti socio-economici e di significativi progressi tecnici, la gestione dei giardini storici e degli spazi verdi in genere, sta vivendo un periodo di forte cambiamento ed evoluzione. 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. Già nella sua versione prototipale, il sistema proposto mostra tutte le sue potenzialità di monitoraggio e supporto alle attività gestionali e manutentive degli spazi verdi, aprendo la strada a una progressiva automazione e virtualizzazione delle procedure (creazione di scenari, elementi essenziali per la successiva valorizzazione e promozione del bene a livello sociale e culturale.In particolare, oltre allo schema logico del sistema, si discutono alcune tra le funzioni di monitoraggio di maggiore interesse (disponibilità idrica, stato fitosanitario e fenologia, evidenziando quali siano i vantaggi

    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.

    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.

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.

    Full Text Available The main issue that European agriculture is facing is related to maintaining and if possible increasing yields while reducing inputs - especially pesticides, including herbicides. Society is paying increasing attention to the quality of products as well as to the sustainability of the productive system. Control of weeds is necessary to achieve economically acceptable yields. The main tool is chemical weed control. This practice spread quickly after its introduction, due its efficacy and simplicity, but it also generated a series of agronomic and environmental issues. One of the solutions to maintain yields, while reducing herbicide use is the adoption of the Integrated Weed Management (IWM. IWM is based on the knowledge of weeds and their response to cropping practices, weed-crop competitive relationships and chemical and non-chemical means of control. IWM has had a quite remarkable success among researchers, politicians and public opinion, but has rarely been applied by farmers. The limited implementation of this management approach may have different explanations: i IWM is more complex than conventional management as it requires greater skill and is more time consuming; ii there is a lack of financial support and demonstration farms, necessary to convince the farmers to adopt it; iii IWM is considered riskier than conventional management; iv research has not succeeded in transferring scientific knowledge to the productive systems.The paper includes an analysis of several examples of IWM application in Italy in recent years (development of decision support systems, predictive models, formation of GIRE (Italian Herbicide Resistance Working Group with the objective of defining their benefits and drawbacks and finding new solutions for the future. It is also underlined that the main difficulty in IWM development is the lack of integration between means of control and proactive agronomic practices that are suitable to prevent the spread and evolution of weeds in the fields.

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.

    The planetary science decadal survey for 2013-2022 (Vision and Voyages, NRC 2011) has promoted mission concepts for sample acquisition from small solar system bodies. Numerous comet-sampling tools are in development to meet this standard. Manufactured Porous Ambient Surface Simulants (MPASS) materials provide an opportunity to simulate variable features at ambient temperatures and pressures to appropriately test potential sample acquisition systems for comets, asteroids, and planetary surfaces. The original "flavor" of MPASS materials is known as Manufactured Porous Ambient Comet Simulants (MPACS), which was developed in parallel with the development of the Biblade Comet Sampling System (Backes et al., in review). The current suite of MPACS materials was developed through research of the physical and mechanical properties of comets from past comet missions results and modeling efforts, coordination with the science community at the Jet Propulsion Laboratory and testing of a wide range of materials and formulations. These simulants were required to represent the physical and mechanical properties of cometary nuclei, based on the current understanding of the science community. Working with cryogenic simulants can be tedious and costly; thus MPACS is a suite of ambient simulants that yields a brittle failure mode similar to that of cryogenic icy materials. Here we describe our suite of comet simulants known as MPACS that will be used to test and validate the Biblade Comet Sampling System (Backes et al., in review).

    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.

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.

Se alude aquí a los servicios de agua po ta ble, drenaje, saneamiento, tratamiento de aguas residuales, disposición de residuos sólidos, rastros, panteones y mercados. Ahora son los desafíos ambientales de la autoridad municipal, por lo que deben ser también sus prioridades. Si esos servicios no se atienden oportuna y técnicamente la población sufrirá, se deteriorará gravemente el medio ambiente y disminuirá la calidad de la vida de la comunidad.

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

    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.

    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

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.

    A turbine airfoil usable in a turbine engine and having at least one ambient air cooling system is disclosed. At least a portion of the cooling system may include one or more cooling channels configured to receive ambient air at about atmospheric pressure. The ambient air cooling system may have a tip static pressure to ambient pressure ratio of at least 0.5, and in at least one embodiment, may include a tip static pressure to ambient pressure ratio of between about 0.5 and about 3.0. The cooling system may also be configured such that an under root slot chamber in the root is large to minimize supply air velocity. One or more cooling channels of the ambient air cooling system may terminate at an outlet at the tip such that the outlet is aligned with inner surfaces forming the at least one cooling channel in the airfoil to facilitate high mass flow.

    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.

    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).

    2013-10-01

    Plants are exposed to daily and seasonal fluctuations in temperature. Within the 'ambient' temperature range (about 12-27°C for Arabidopsis) temperature differences have large effects on plant growth and development, disease resistance pathways and the circadian clock without activating temperature stress pathways. It is this developmental sensing and response to non-stressful temperatures that will be covered in this review. Recent advances have revealed key players in mediating temperature signals. The bHLH transcription factor PHYTOCHROME INTERACTING FACTOR4 (PIF4) has been shown to be a hub for multiple responses to warmer temperature in Arabidopsis, including flowering and hypocotyl elongation. Changes in chromatin state are involved in transmitting temperature signals to the transcriptome. Determining the precise mechanisms of temperature perception represents an exciting goal for the field. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Une caracterisation des emissions atmospheriques provenant des sources fixes en operation, alimentees au gaz et a l'huile legere, a ete conduite aux installations visees des sites no.1 et no.2. 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. Des tests de combustion sur une base reguliere sont donc recommandes. Afin de supporter le processus de suivi et d'evaluation de la performance environnementale des sources fixes, un outil d'aide a la gestion de l'information environnementale a ete developpe. Dans ce contexte, la poursuite du developpement d'un outil d'aide a la gestion de l'information environnementale faciliterait non seulement le travail des personnes affectees aux inventaires annuels mais egalement le processus de communication entre les differents acteurs concernes tant intra- qu'inter-etablissement.

    We visualized the density distributions of C 2 (plume), NO (ambient gas), and CN (reaction product) when a graphite target was ablated by irradiating YAG laser pulses at wavelengths of 1064 and 355 nm in ambient gas mixture of NO and He. It has been shown by the density distributions of C 2 and NO that the expansion of the plume removes the ambient gas and the plume and the ambient gas locate exclusively in both the cases at 1064 and 355 nm. A high CN density was observed at the interface between the plume and the ambient gas at 1064 nm, which is reasonable since chemical reactions between the plume and the ambient gas may occur only at their interface. On the other hand, in the case at 355 nm, we observed considerable CN inside the plume, indicating that the chemical reaction processes in the laser ablation at 355 nm is different from that expected from the density distributions of the plume and the ambient gas

  5. 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. Partindo dessa premissa é que este trabalho está enfocando os seguintes tópicos: Responsabilidade Social da Empresa; A Empresa e o Meio Ambiente; Gestão Ambiental; Sistema de Gestão Ambiental; Ações para Preservar o Meio Ambiente - O Protocolo Verde, A Contabilidade, Custos Ambientais, Ativo Ambiental, Passivo Ambiental, Patrimônio Ambiental, Contabilidade Ambiental e Contabilidade Ambiental - o Passaporte para a Competitividade.

    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.

  15. Retrieval of reflections from ambient noise using illumination diagnosis

    Vidal, C. Almagro; Draganov, D.; van der Neut, J.; Drijkoningen, G.; Wapenaar, K.

    2014-09-01

    Seismic interferometry (SI) enables the retrieval of virtual sources at the location of receivers. In the case of passive SI, no active sources are used for the retrieval of the reflection response of the subsurface, but ambient-noise recordings only. The resulting retrieved response is determined by the illumination characteristics of the recorded ambient noise. Characteristics like geometrical distribution and signature of the noise sources, together with the complexity of the medium and the length of the noise records, determine the quality of the retrieved virtual-shot events. To retrieve body wave reflections, one needs to correlate body-wave noise. A source of such noise might be regional seismicity. In regions with notable human presence, the dominant noise sources are generally located at or close to the surface. In the latter case, the noise will be dominated by surface waves and consequently also the retrieved virtual common-source panels will contain dominant retrieved surface waves, drowning out possible retrieved reflections. In order to retrieve reflection events, suppression of the surface waves becomes the most important pre-processing goal. Because of the reasons mentioned above, we propose a fast method to evaluate the illumination characteristics of ambient noise using the correlation results from ambient-noise records. The method is based on the analysis of the so-called source function of the retrieved virtual-shot panel, and evaluates the apparent slowness of arrivals in the correlation results that pass through the position of the virtual source and at zero time. The results of the diagnosis are used to suppress the retrieval of surface waves and therefore to improve the quality of the retrieved reflection response. We explain the approach using modelled data from transient and continuous noise sources and an example from a passive field data set recorded at Annerveen, Northern Netherlands.

    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.

    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

    2000-09-01

    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.

  14. On the role of ambient environments in the collapse of Bonnor-Ebert spheres

    International Nuclear Information System (INIS)

    Kaminski, Erica; Frank, Adam; Carroll, Jonathan; Myers, Phil

    2014-01-01

    We consider the interaction between a marginally stable Bonnor-Ebert (BE) sphere and the surrounding ambient medium. In particular, we explore how the infall from an evolving ambient medium can trigger the collapse of the sphere using three-dimensional adaptive mesh refinement simulations. We find the resulting collapse dynamics to vary considerably with ambient density. In the highest ambient density cases, infalling material drives a strong compression wave into the cloud. It is the propagation of this wave through the cloud interior that triggers the subsequent collapse. For lower ambient densities, we find the main trigger of collapse to be a quasistatic adjustment of the BE sphere to gravitational settling of the ambient gas. In all cases, we find that the classic 'outside-in' collapse mode for super-critical BE spheres is recovered before a protostar (i.e., sink particle) forms. Our work supports scenarios in which BE dynamics naturally begins with either a compression wave or infall dominated phase, and only later assumes the usual outside-in collapse behavior.

    2015-10-01

    Full Text Available Ambient systems provide information in the periphery of a user’s attention. Their aim is to present information as unobtrusively as possible to avoid interrupting primary tasks (e.g. writing or reading. 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.

    In 2006, the Argentine Nuclear Regulatory Authority has initiated a regulatory knowledge management process to face the loss of knowledge resulting from retiring experts, the generation gap, and the existing need to train new human resources. A number of projects have been started together with the technical assistance of the National Public Administration Institute to preserve knowledge and render it explicit for the coming generations. These projects include 'The History of the Expert's Learning Process' in which the majority of the most critical experts have been interviewed so far. The results of this project help envision a training structure and prospective projects. An Internet Site has also been created on the Intranet in order to render knowledge explicit and facilitate the tools for knowledge management initiatives. Furthermore, ARN's knowledge map project has also been started.

    Full Text Available 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.

    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.

  10. 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.

    Surface and structural properties of the laser irradiated titanium targets have been investigated under dry and wet ambient environments. For this purpose KrF Excimer laser of wavelength 248 nm, pulse duration of 20 ns and repetition rate of 20 Hz has been employed. The targets were exposed for various number of laser pulses ranging from 500 to 2000 in the ambient environment of air, de-ionized water and propanol at a fluence of 3.6 J/cm 2 . The surface morphology, chemical composition and crystallographical analysis were performed by using Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDS) and X-ray Diffraction (XRD), respectively. For both central and peripheral ablated areas, significant difference in surface morphology has been observed in case of dry and wet ambient conditions. Large sized and diffused grains are observed in case of dry ablation. Whereas, in case of wet ablation, small sized, and well defined grains with distinct grain boundaries and significantly enhanced density are revealed. This difference is ascribed to the confinement effects of the liquid. The peripheral ablated area shows redeposition in case of dry ablation whereas small sized grain like structures are formed in case of wet ablation. EDS analysis exhibits variation in chemical composition under both ambient conditions. When the targets are treated in air environment, enhancement of the oxygen as well as nitrogen content is observed while in case of de-ionized water and propanol only increase in content of oxygen is observed. X-ray diffraction analysis exhibits formation of oxides and nitrides in case of air, whereas, in case of de-ionized water and propanol only oxides along with hydrides are formed. For various number of laser pulses the variation in the peak intensity, crystallinity and d-spacing is observed under both ambient conditions.

    We analyze continuous ambient-field data at Groningen gas field (Netherlands) through cross-correlation processing. The Groningen array is composed of 75 shallow boreholes with 6 km spacing, which contain a 3C surface accelerometer and four 5-Hz 3C borehole geophones spaced at 50 m depth intervals. We successfully retrieve coherent waves from ambient seismic field on the 9 components between stations. Results show high SNR signal in the frequency range of 0.125-1 Hz, and the ZZ, ZR, RZ, RR and TT components show much stronger wave energy than other components as expected. This poster discuss the different type of waves retrieved, the utility of the combination of borehole and surface observations, future development as well as the importance to compute the 9 components of the Green's tensor to better understand the wave field propriety with ambient noise.

    The rapid economic growth in China is coupled with a severe ambient air pollution, which poses a huge threat to human health and the sustainable development of social economy. The rapid urbanization and industrialization over the last three decades have placed China as one of countries with the greatest disease burden in world. Notably, the prevalence rate of chronic noncommunicable diseases (CND), including respiratory diseases, CVD, and stroke, in 2010 reaches 16.9%. The continuous growth of the incidence of CND urgent needs for effective regulatory action for health protection. This study aims to evaluate the impact of rapid urbanization on status of ambient air pollution and associated adverse health effects on the incidence and the burden of CND and risk assessment. Our findings would be greatly significant in the prediction of the risk of ambient air pollution on CND and for evidence-based policy making and risk management in China.

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.

    2011-12-01

    Full Text Available We present results from two field deployments of a unique tandem differential mobility analyzer (TDMA configuration with two primary capabilities: identifying alternative stable or meta-stable ambient aerosol hydration states associated with hysteresis in aerosol hydration behavior and determining the actual Ambient hydration State (AS-TDMA. This data set is the first to fully classify the ambient hydration state of aerosols despite recognition that hydration state significantly impacts the roles of aerosols in climate, visibility and heterogeneous chemistry. The AS-TDMA was installed at a site in eastern Tennessee on the border of Great Smoky Mountains National Park for projects during the summer of 2006 and winter of 2007–2008. During the summer, 12% of the aerosols sampled in continuous AS-TDMA measurements were found to posses two possible hydration states under ambient conditions. In every case, the more hydrated of the possible states was occupied. The remaining 88% did not posses multiple possible states. In continuous measurements during the winter, 49% of the aerosols sampled possessed two possible ambient hydration states; the remainder possessed only one. Of those aerosols with multiple possible ambient hydration states, 65% occupied the more hydrated state; 35% occupied the less hydrated state. This seasonal contrast is supported by differences in the fine particulate (PM2.5 composition and ambient RH as measured during the two study periods. In addition to seasonal summaries, this work includes case studies depicting the variation of hydration state with changing atmospheric conditions.

    2008-01-01

    Management of ambient concentrations of Volatile Organic Compounds (VOCs) is essential for maintaining low ozone levels in urban areas where its formation is under a VOC-limited regime. The significant decrease in traffic-induced VOC emissions in many developed countries resulted in relatively comparable shares of traffic and non-traffic VOC emissions in urban airsheds. A key step for urban air quality management is allocating ambient VOC concentrations to their pertinent sources. This study presents an approach that can aid in identifying sources that contribute to observed BTEX concentrations in areas characterized by low BTEX concentrations, where traditional source apportionment techniques are not useful. Analysis of seasonal and diurnal variations of ambient BTEX concentrations from two monitoring stations located in distinct areas reveal the possibility to identify source categories. Specifically, the varying oxidation rates of airborne BTEX compounds are used to allocate contributions of traffic emissions and evaporative sources to observed BTEX concentrations. - BTEX sources are identified from temporal variations of ambient concentration

  16. 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

    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

    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.

    Introduction La qualité des vaccins conditionne les résultats attendus de la vaccination. Elle est tributaire de l'efficacité de système de gestion technique et logistique mis en place. Cette étude est menée pour évaluer l'efficacité de la gestion des vaccins et d'en tirer des leçons. Méthodes Une étude rétrospective est menée pendant la période de 2010 à 2014 sur la gestion logistique de vaccins au niveau de l'antenne PEV Kisangani. La revue documentaire complétée par les entretiens semi-dirigés des gestionnaires et prestataires de services de vaccination ont permis d'évaluer la gestion de vaccins en se servant des modèle GEV de l'OMS, en vue de dégager les écarts. Résultats Il est observé une faible connaissance des prestataires sur les vaccins qui ne peuvent pas être congelés, sur les tests de congélation et d'autres dommages de vaccins. La gestion informatisée des données au niveau de l'antenne est correctement assurée. Aucun critère évalué n'a atteint l'objectif de 80%. Le respect de la température de stockage est de 70% au niveau de l'antenne ; le critère relatif à la gestion de vaccins est respectivement de 65% et 67% au niveau du BCZ et CS. Le critère relatif à la maintenance est nul à tous les niveaux. Conclusion Le dysfonctionnement de système logistique est remarquable à tous les niveaux de la pyramide sanitaire, ceci pourrait interférer avec la qualité et l'impact attendu de la vaccination. Une attention particulière doit être accordée à la maintenance des équipements. PMID:28748006

    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.

    Gagnon, Olaf

    In recent times, when we think of major disasters, whether they are natural or a result of our activities, we often think of satellite images of the affected areas. This comes in part from the media coverage of such events that uses more and more the same data sources that we use to help plan and manage relief efforts. The processing and analysis of satellite images, in such contexts, is of great assistance because of the numerous types of information we can glean from them and the diverse uses we can put them to during the different steps involved in disaster management. To this effect, the various techniques and tools used in remote sensing, that were developed by research teams, analysts and photo interpreters, are used efficiently to help in the rapid treatment and analysis of satellite images as well as the creation of value added cartographic products that are likely to help in relief management. This paper deals with one of the many technical aspects that is particularly well suited to the analysis of crisis images, change detection. It is easily understandable that the analysis, entailed by the use of satellite images in the context of disaster management, is essentially the comparison of what "was" before the catastrophe with what "is" after it has happened. In light of this, it seems that change detection is the most appropriate tool to use in such situations, but is this truly the case? To answer this question, we will present the sequence of operations entailed by the use and analysis of satellite images as well as the technical constraints and pitfalls that must be considered as pertains to the context of disaster management and the problems associated with the use of change detection. We will underline the pertinent conceptual, technical and functional concepts that must be taken into consideration to increase the usability of change detection in disaster management.

    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.

    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.

    Refuelling the 10 to 15 MW pool type reactor considered here will occur frequently (some 10 elements every 3 to 4 weeks). It is therefore necessary to determine the most economic fuel policy. This study proposes to define a strategy that will make it possible to decide on the number and characteristics of the shipment containers, as well as on the means of storage, so as to reduce the risks as much as possible should the basic parameters of the study vary. Among these parameters, the respective influence of which is investigated, chemical reprocessing costs play a vital part. Two examples of optimum fuel management are given according to whether the reprocessing charges applied are those of the old or of the 1961 U.S. AEC base charges for reprocessing highly enriched irradiated fuel.

This study start from the fact that an important methods exist for evaluation transport of dangerous materials in cities, risk analysis and emergency plans related to classified installations, management of quality of water, 'chronic' industrial risks at local and regional level, probabilistic estimation for industrial plants. The objective is in fact to show what risk analysis could bring to the municipality, the city or the region. [French] Alors que la responsabilite de la maitrise du risque repose de plus en plus sur les collectivites territoriales, soit dans la mouvance naturelle de la decentralisation, soit par des textes specifiques, les moyens d'evaluation et les regles de gestion sont encore tres peu developpes.

  13. 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

  17. Densification of silica glass at ambient pressure

    We show that densification of silica glass at ambient pressure as observed in irradiation experiments can be attributed to defect generation and subsequent structure relaxation. In our molecular dynamics simulations, defects are created by randomly removing atoms, by displacing atoms from their nominal positions in an otherwise intact glass, and by assigning certain atom excess kinetic energy (simulated ion implantation). The former forms vacancies; displacing atoms and ion implantation produce both vacancies and 'interstitials'. Appreciable densification is induced by these defects after equilibration of the defective glasses. The structural and vibrational properties of the densified glasses are characterized, displaying resembling features regardless of the means of densification. These results indicate that relaxation of high free-energy defects into metastable amorphous structures enriched in atomic coordination serves as a common mechanism for densification of silica glass at ambient pressure

    Mass spectrometry imaging (MSI) has emerged as an important tool in the last decade and it is beginning to show potential to provide new information in many fields owing to its unique ability to acquire molecularly specific images and to provide multiplexed information, without the need for labeling or staining. In MSI, the chemical identity of molecules present on a surface is investigated as a function of spatial distribution. In addition to now standard methods involving MSI in vacuum, recently developed ambient ionization techniques allow MSI to be performed under atmospheric pressure on untreated samples outside the mass spectrometer. Here we review recent developments and applications of MSI emphasizing the ambient ionization techniques of desorption electrospray ionization (DESI), laser ablation electrospray ionization (LAESI), probe electrospray ionization (PESI), desorption atmospheric pressure photoionization (DAPPI), femtosecond laser desorption ionization (fs-LDI), laser electrospray mass spectrometry (LEMS), infrared laser ablation metastable-induced chemical ionization (IR-LAMICI), liquid microjunction surface sampling probe mass spectrometry (LMJ-SSP MS), nanospray desorption electrospray ionization (nano-DESI), and plasma sources such as the low temperature plasma (LTP) probe and laser ablation coupled to flowing atmospheric-pressure afterglow (LA-FAPA). Included are discussions of some of the features of ambient MSI including the ability to implement chemical reactions with the goal of providing high abundance ions characteristic of specific compounds of interest and the use of tandem mass spectrometry to either map the distribution of targeted molecules with high specificity or to provide additional MS information in the structural identification of compounds. We also describe the role of bioinformatics in acquiring and interpreting the chemical and spatial information obtained through MSI, especially in biological applications for tissue

    The detection of volatile vapors of unknown species in a complex field environment is required in many different applications. Mass spectroscopic techniques require subsystems including an ionization unit and sample transport mechanism. All of these subsystems must have low mass, small volume, low power, and be rugged. A volatile molecular detector, an ambient pressure pyroelectric ion source (APPIS) that met these requirements, was recently reported by Caltech researchers to be used in in situ environments.

    Hepatocellular carcinoma (HCC), the most commonly occurring type of primary liver cancer, has been increasing in incidence worldwide. Vitamin D, acquired from sunlight exposure, diet, and dietary supplements, has been hypothesized to impact hepatocarcinogenesis. However, previous epidemiologic studies examining the associations between dietary and serum vitamin D reported mixed results. The purpose of this study was to examine the association between ambient ultraviolet (UV) radiation exposure and HCC risk in the U.S. The Surveillance, Epidemiology, and End Results (SEER) database provided information on HCC cases diagnosed between 2000 and 2014 from 16 population-based cancer registries across the U.S. Ambient UV exposure was estimated by linking the SEER county with a spatiotemporal UV exposure model using a geographic information system. Poisson regression with robust variance estimation was used to calculate incidence rate ratios (IRRs) and 95% confidence intervals (CIs) for the association between ambient UV exposure per interquartile range (IQR) increase (32.4 mW/m 2 ) and HCC risk adjusting for age at diagnosis, sex, race, year of diagnosis, SEER registry, and county-level information on prevalence of health conditions, lifestyle, socioeconomic, and environmental factors. Higher levels of ambient UV exposure were associated with statistically significant lower HCC risk (n = 56,245 cases; adjusted IRR per IQR increase: 0.83, 95% CI 0.77, 0.90; p ambient UV and HCC risk was observed among males (p for interaction = 0.01) and whites (p for interaction = 0.01). Higher ambient UV exposure was associated with a decreased risk of HCC in the U.S. UV exposure may be a potential modifiable risk factor for HCC that should be explored in future research.

    Highlights: • Ambient pressure photoemission spectroscopy of metals. • Rastered photon energy scan overcomes inelastic scattering. • Relationship between photoemission threshold and contact potential difference. - Abstract: We describe a novel photoemission technique utilizing a traditional Kelvin probe as a detector of electrons/atmospheric ions ejected from metallic surfaces (Au, Ag, Cu, Fe, Ni, Ti, Zn, Al) illuminated by a deep ultra-violet (DUV) source under ambient pressure. To surmount the limitation of electron scattering in air the incident photon energy is rastered rather than applying a variable retarding electric field as is used with UPS. This arrangement can be applied in several operational modes: using the DUV source to determine the photoemission threshold (Φ) with 30–50 meV resolution and also the Kelvin probe, under dark conditions, to measure contact potential difference (CPD) between the Kelvin probe tip and the metallic sample with an accuracy of 1–3 meV. We have studied the relationship between the photoelectric threshold and CPD of metal surfaces cleaned in ambient conditions. Inclusion of a second spectroscopic visible source was used to confirm a semiconducting oxide, possibly Cu{sub 2}O, via surface photovoltage measurements with the KP. This dual detection system can be easily extended to controlled gas conditions, relative humidity control and sample heating/cooling.

    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.

    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.)

Na parte arenosa, o meio ambiente é afetado por fenômenos de erosão que produzem formas eólicas espetaculares (arenização que fazem pensar as dos desertos. A produção agrícola ali desenvolvida necessita de água para a irrigação do arroz. Os pesticidas que são utilizados para os cultivos podem poluir os recursos hídricos. A mata ciliar é desmatada em diversos lugares. A gestão sustentável dos recursos hídricos e dos solos desta região necessita de ações de conservação. Por essa razão surgem estes questionamentos: Como os agricultores percebem estes fenômenos? Constituem para eles algum problema? Como racionalizam suas práticas? Com que redes estes agricultores estão interligados? Quais são suas interações com o governo? A metodologia desta pesquisa se apóia em entrevistas realizadas com 23 agricultores para procurar compreender melhor as suas percepções e os seus modos de gestão em relação ao meio ambiente e também identificar as variáveis sociais que explicam as diferenças de comportamento.Os resultados que obtivemos mostram que poucos agricultores percebem as suas responsabilidades em relação à gravidade do processo de arenização e do estado dos recursos hídricos. Os agricultores que perceberam o risco da falta de água o atribuíram essencialmente à seca e não a uma exploração excessiva dos recursos, ao mesmo tempo em que negligenciam a poluição. A erosão dos solos nas zonas de arenização não é considerada como um problema, estes espaços são improdutivos pois não ameaçam a rentabilidade global das explorações agrícolas. O que mais preocupa os agricultores é a erosão nas partes cultivadas o que levou grande parte deles a optar pelo plantio direto. O conhecimento dos problemas ambientais locais e a realização de práticas de conservação também parecem não ser preocupação do

    This work presents a synthesis of three points: the environment, energy and man. The consideration of these aspects allows us to confront the unequal distribution of energy resources, the constraints and political influences which determine the exploitation of these energy resources, and the concentration of the consumption of energy by one fifth of the world`s population and the perspective of future growth of energy use by the remaining four-fifths. It is understanding of the importance and the benefits of reducing energy requirements, combined with the environmental perspectives, that forms the core of the Integrated Resource Planning of Least is proposed. This framework will utilize the knowledge of the engineer for developing a system to aid with decision making and the management of information, and particularly with the notions henceforth referred to as `Demand-Site Management` as applied to the electrical grid. The model of such a Management Information System which demonstrates these theoretical advances is called SIADEME (Systeme Interactif d`Aide a la Decision et de Gestion des Actions de Maitrise de la Demande d`energie).

    Ambient air pollution is associated with systemic increases in oxidative stress, to which sperm are particularly sensitive. Although decrements in semen quality represent a key mechanism for impaired fecundability, prior research has not established a clear association between air pollution and semen quality. To address this, we evaluated the association between ambient air pollution and semen quality among men with moderate air pollution exposure. Of 501 couples in the LIFE study, 467 male partners provided one or more semen samples. Average residential exposure to criteria air pollutants and fine particle constituents in the 72 days before ejaculation was estimated using modified Community Multiscale Air Quality models. Generalized estimating equation models estimated the association between air pollutants and semen quality parameters (volume, count, percent hypo-osmotic swollen, motility, sperm head, morphology and sperm chromatin parameters). Models adjusted for age, body mass index, smoking and season. Most associations between air pollutants and semen parameters were small. However, associations were observed for an interquartile increase in fine particulates ≤2.5 µm and decreased sperm head size, including -0.22 (95% CI -0.34, -0.11) µm 2 for area, -0.06 (95% CI -0.09, -0.03) µm for length and -0.09 (95% CI -0.19, -0.06) µm for perimeter. Fine particulates were also associated with 1.03 (95% CI 0.40, 1.66) greater percent sperm head with acrosome. Air pollution exposure was not associated with semen quality, except for sperm head parameters. Moderate levels of ambient air pollution may not be a major contributor to semen quality.

  20. Towards full waveform ambient noise inversion

    Sager, Korbinian; Ermert, Laura; Boehm, Christian; Fichtner, Andreas

    2018-01-01

    In this work we investigate fundamentals of a method—referred to as full waveform ambient noise inversion—that improves the resolution of tomographic images by extracting waveform information from interstation correlation functions that cannot be used without knowing the distribution of noise sources. The fundamental idea is to drop the principle of Green function retrieval and to establish correlation functions as self-consistent observables in seismology. This involves the following steps: (1) We introduce an operator-based formulation of the forward problem of computing correlation functions. It is valid for arbitrary distributions of noise sources in both space and frequency, and for any type of medium, including 3-D elastic, heterogeneous and attenuating media. In addition, the formulation allows us to keep the derivations independent of time and frequency domain and it facilitates the application of adjoint techniques, which we use to derive efficient expressions to compute first and also second derivatives. The latter are essential for a resolution analysis that accounts for intra- and interparameter trade-offs. (2) In a forward modelling study we investigate the effect of noise sources and structure on different observables. Traveltimes are hardly affected by heterogeneous noise source distributions. On the other hand, the amplitude asymmetry of correlations is at least to first order insensitive to unmodelled Earth structure. Energy and waveform differences are sensitive to both structure and the distribution of noise sources. (3) We design and implement an appropriate inversion scheme, where the extraction of waveform information is successively increased. We demonstrate that full waveform ambient noise inversion has the potential to go beyond ambient noise tomography based on Green function retrieval and to refine noise source location, which is essential for a better understanding of noise generation.

    Full Text Available The demographic change towards an aging population is creating a significant impact and introducing drastic challenges to our society. We therefore need to find ways to assist older people to stay independently and prevent social isolation of these population. Information and Communication Technologies (ICT provide various solutions to help older adults to improve their quality of life, stay healthier, and live independently for a time. Ambient Assisted Living (AAL is a field to investigate innovative technologies to provide assistance as well as healthcare and rehabilitation to impaired seniors. The paper provides a review of research background and technologies of AAL.

    An ambient odour of anise was used in a context-dependent memory study with three different memory tasks targeting both declarative and non-declarative memory functions. Declarative memory was assessed by means of two episodic memory tests; recall of a prose text and a complex figure. Priming was used to assess the non-declarative memory with word fragment completion. Memory was tested immediately and after 48 hours. The results showed a significant main effect of context (odour or not) for a...

    Ambient ultrafine particle number concentrations (PNC) have inhomogeneous spatio-temporal distributions and depend on a number of different urban factors, including background conditions and distant sources. This paper quantitatively compares exposure to ambient ultrafine particles at urban schools in two cities in developed countries, with high insolation climatic conditions, namely Brisbane (Australia) and Barcelona (Spain). The analysis used comprehensive indoor and outdoor air quality measurements at 25 schools in Brisbane and 39 schools in Barcelona. PNC modes were analysed with respect to ambient temperature, land use and urban characteristics, combined with the measured elemental carbon concentrations, NOx (Brisbane) and NO2 (Barcelona). The trends and modes of the quantified weekday average daily cycles of ambient PNC exhibited significant differences between the two cities. PNC increases were observed during traffic rush hours in both cases. However, the mid-day peak was dominant in Brisbane schools and had the highest contribution to total PNC for both indoors and outdoors. In Barcelona, the contribution from traffic was highest for ambient PNC, while the mid-day peak had a slightly higher contribution for indoor concentrations. Analysis of the relationships between PNC and land use characteristics in Barcelona schools showed a moderate correlation with the percentage of road network area and an anti-correlation with the percentage of green area. No statistically significant correlations were found for Brisbane. Overall, despite many similarities between the two cities, school-based exposure patterns were different. The main source of ambient PNC at schools was shown to be traffic in Barcelona and mid-day new particle formation in Brisbane. The mid-day PNC peak in Brisbane could have been driven by the combined effect of background and meteorological conditions, as well as other local/distant sources. The results have implications for urban development

    Robinson, Patricia S; Green, Jeanette

    2015-01-01

    We sought to examine the effect of exposure to an ambient environment in a pediatric emergency department. We hypothesized that passive distraction from ambient lighting in an emergency department would lead to reduction in patient pain and anxiety and increased caregiver satisfaction with services. Passive distraction has been associated with lower anxiety and pain in patients and affects perception of wait time. A pediatric ED was designed that optimized passive distraction techniques using colorful ambient lighting. Participants were nonrandomly assigned to either an ambient ED environment or a traditional ED environment. Entry and exit questionnaires assessed caregiver expectations and experiences. Pain ratings were obtained with age-appropriate scales, and wait times were recorded. A total of 70 participants were assessed across conditions, that is, 40 in the ambient ED group and 30 in the traditional ED group. Caregivers in the traditional ED group expected a longer wait, had higher anxiety pretreatment, and felt more scared than those in the ambient ED group. Caregivers in the ambient ED group felt more included in the care of their child and rated quality of care higher than caregivers in the traditional ED group. Pain ratings and administrations of pain medication were lower in the ambient ED group. Mean scores for the ambient ED group were in the expected direction on several items measuring satisfaction with ED experiences. Results were suggestive of less stress in caregivers, less pain in patients, and higher satisfaction levels in the ambient ED group. © The Author(s) 2015.

  16. Ambient Noise in an Urbanized Tidal Channel

    Science.gov (United States)

    Bassett, Christopher

    In coastal environments, when topographic and bathymetric constrictions are combined with large tidal amplitudes, strong currents (> 2 m/s) can occur. Because such environments are relatively rare and difficult to study, until recently, they have received little attention from the scientific community. However, in recent years, interest in developing tidal hydrokinetic power projects in these environments has motivated studies to improve this understanding. In order to support an analysis of the acoustic effects of tidal power generation, a multi-year study was conducted at a proposed project site in Puget Sound (WA) are analyzed at a site where peak currents exceeded 3.5 m/s. From these analyses, three noise sources are shown to dominate the observed variability in ambient noise between 0.02-30 kHz: anthropogenic noise from vessel traffic, sediment-generated noise during periods of strong currents, and flow-noise resulting from turbulence advected over the hydrophones. To assess the contribution of vessel traffic noise, one calendar year of Automatic Identification System (AIS) ship-traffic data was paired with hydrophone recordings. The study region included inland waters of the Salish Sea within a 20 km radius of the hydrophone deployment site in northern Admiralty Inlet. The variability in spectra and hourly, daily, and monthly ambient noise statistics for unweighted broadband and M-weighted sound pressure levels is driven largely by vessel traffic. Within the one-year study period, at least one AIS transmitting vessel is present in the study area 90% of the time and over 1,363 unique vessels are recorded. A noise budget for vessels equipped with AIS transponders identifies cargo ships, tugs, and passenger vessels as the largest contributors to noise levels. A simple model to predict received levels at the site based on an incoherent summation of noise from different vessel types yields a cumulative probability density function of broadband sound pressure

Quoiqu’on puisse constater que le modèle de demande psychologique - autonomie décisionnelle de Karasek et Theorell- trouve aussi son application dans les milieux de travail qui empruntent cette forme, on observe, en fait, des formes particulières de ces facteurs dans la forme d’organisation du travail propre à la gestion par projets. Assimilables à « l’hypersollicitation par le client » comme il a été repéré par Christophe Dejours, ces formes ont été observées lors d’une enquête menée récemment sur la conciliation entre la vie privée et la vie professionnelle dans sept organisations montréalaises. La recherche qualitative a recueilli en tout le discours de 88 répondants distribués également selon le sexe et exerçant des fonctions liées au génie informatique. Ces observations permettent d’envisager une nuance au modèle théorique de la santé mentale ci-haut mentionné, visant à tenir compte des effets délétères d’une très grande latitude décisionnelle assortie de très grandes responsabilités chez des travailleurs hautement qualifiés.Are there distinct mental health problems among workers in the new economy? Although we may observe that the psychological demand - decision latitude model of Karakek and Theorell is appropriate and also finds its application in this type of workplace, we also notice some particular forms that these factors take in the management-by-project work organization model. Akin to the so-called "client’s hyper-demanding activity" as identified by Christophe Dejours, these forms were observed during a recent field study about balancing work and family in seven Montreal organizations.

    2014-01-01

    The smart home, ambient intelligence and ambient assisted living have been intensively researched for decades. Although rural areas are an important potential market, because they represent about 80% of the territory of the EU countries and around 125 million inhabitants, there is currently a lack of applicable AAL solutions. This paper discusses the theoretical foundations of AAL in rural areas. This discussion is underlined by the achievements of the empirical field study, Casa Vecchia, which has been carried out over a four-year period in a rural area in Austria. The major goal of Casa Vecchia was to evaluate the feasibility of a specific form of AAL for rural areas: bringing AAL technology to the homes of the elderly, rather than moving seniors to special-equipped care facilities. The Casa Vecchia project thoroughly investigated the possibilities, challenges and drawbacks of AAL related to this specific approach. The findings are promising and somewhat surprising and indicate that further technical, interactional and socio-psychological research is required to make AAL in rural areas reasonable in the future.

    The kitchen environment is one of the scenarios in the home where users can benefit from Ambient Assisted Living (AAL) applications. Moreover, it is the place where old people suffer from most domestic injuries. This paper presents a novel design, implementation and assessment of a Smart Kitchen which provides Ambient Assisted Living services; a smart environment that increases elderly and disabled people's autonomy in their kitchen-related activities through context and user awareness, appropriate user interaction and artificial intelligence. It is based on a modular architecture which integrates a wide variety of home technology (household appliances, sensors, user interfaces, etc.) and associated communication standards and media (power line, radio frequency, infrared and cabled). Its software architecture is based on the Open Services Gateway initiative (OSGi), which allows building a complex system composed of small modules, each one providing the specific functionalities required, and can be easily scaled to meet our needs. The system has been evaluated by a large number of real users (63) and carers (31) in two living labs in Spain and UK. Results show a large potential of system functionalities combined with good usability and physical, sensory and cognitive accessibility.

    The pursuit of high-throughput sample analysis from complex matrix demands development of multiple ionization techniques with complementary specialties. A versatile integrated ambient ionization source (iAmIS) platform is proposed in this work, based on the idea of integrating multiple functions, enhancing the efficiency of current ionization techniques, extending the applications, and decreasing the cost of the instrument. The design of the iAmIS platform combines flowing atmospheric pressure afterglow (FAPA) source/direct analysis in real time (DART), dielectric barrier discharge ionization (DBDI)/low-temperature plasma (LTP), desorption electrospray ionization (DESI), and laser desorption (LD) technique. All individual and combined ionization modes can be easily attained by modulating parameters. In particular, the FAPA/DART&DESI mode can realize the detection of polar and nonpolar compounds at the same time with two different ionization mechanisms: proton transfer and charge transfer. The introduction of LD contributes to the mass spectrometry imaging and the surface-assisted laser desorption (SALDI) under ambient condition. Compared with other individual or multi-mode ion source, the iAmIS platform provides the flexibility of choosing different ionization modes, broadens the scope of the analyte detection, and facilitates the analysis of complex samples.

  7. On the attenuation of the ambient seismic field

    2013-01-01

    Although myriad applications exploiting the ambient seismic field have been reported to date, comparatively little attention has been paid to its potential to resolve subsurface attenuation. The ambient seismic field, however, may ultimately prove itself an invaluable asset in constraining subsurface attenuation structure. Especially areas with dense seismometer coverage hold great potential. Moreover, since this coverage continues to grow, significant developments may await in the future. Subsurface structure in terms of attenuation is of great importance for many reasons. For example, knowledge of the attenuation structure may aid in predicting ground motions caused by future large earthquakes. From a scientific perspective, a great deal of new information may be extracted, potentially fostering research in related fields (e.g., geodynamics, hydrology). Both from an environmental and economic point of view, inversion of the ambient seismic wavefield for attenuation structure may in the future provide a means to image hydrocarbon reservoirs. In sufficiently diffuse wavefields, simple cross-correlation of long noise time series recorded by two receivers results in the response at one of the receivers as if there was a source at the position of the other. I present a case study that shows that thus retrieved surface waves can be used to recover attenuation beneath an array of ocean-bottom seismometers. Given the small aperture of the seismic survey, this is unprecedented. Unambiguous interpretation of recovered attenuation values is of major importance. Lack of understanding of the effect that preprocessing has on the amplitude of the noise cross-correlation prevents such unambiguous interpretation. I carefully examine the effect spectral whitening has on the noise cross-correlation. Emphasis is given to the dependence of the amplitudes on the length of the time windows employed in the cross-correlation procedure. Short time-window lengths may require an additional

    Introduction Les antivitamines K (AVK), traitement anticoagulant oral le plus largement prescrit, posent un réel problème de santé publique du fait de leur risque iatrogène. L'objectif de cette étude était de préciser le niveau de connaissance des patients sur la gestion de leur traitement par les AVK. Méthodes Il s'est agi d'une enquête transversale descriptive réalisée au CHU-Yalgado Ouédraogo, sur une période de 03 mois : du 1er mars au 31 mai 2012. Un questionnaire a été administré aux patients bénéficiant d'un traitement AVK depuis au moins un mois. Résultats Soixante-dix patients ont été inclus dans l'étude dont 30 hommes. L'âge moyen était de 49 ans ± 16 ans. Les cardiopathies et la maladie thromboembolique veineuse justifiant l'institution du traitement AVK étaient retrouvées respectivement dans 58,6% et 41,4% des cas. Le nom de l'AVK et la raison exacte du traitement étaient connus respectivement dans 91,4% et 67,1% des cas. Plus de la moitié des patients (68,6%) savaient que les AVK rendaient le sang plus fluide. Quarante-six patients (65,7%) citaient l'INR comme examen biologique de surveillance du traitement et seulement 28 patients (40%) connaissaient les valeurs cibles. La majorité des patients ne connaissait pas les risques encourus en cas de surdosage (72,8%) et de sous-dosage (71,4%). Une automédication par anti-inflammatoire non stéroïdien était signalée par 18 patients (25,7%). Les choux (74,3%) et la laitue (62,9%), aliments à consommer avec modération, étaient les plus cités. Conclusion Les connaissances des patients sur la gestion des AVK étaient fragmentaires et insuffisantes pour assurer la sécurité et l'efficacité du traitement. La création d'un programme d'éducation thérapeutique sur les AVK s'avère alors nécessaire. PMID:25870741

À partir d’entretiens auprès des acteurs de l’eau (irrigants, pêcheurs, riverains, acteurs du tourisme…, nous montrons que si la GV instaure une nouvelle proximité autour de règles d’organisation, celle-ci demeure asymétrique (privilégiant une proximité sectorielle autour de l’irrigation, instrumentale (absence d’un projet partagé de développement territorial, et enfin partielle au sens où n’est pas prise en compte la diversité des interdépendances de proximité autour de l’eau.Since the 90’s in the French region watered by the river Charente water resources have been weighed down with irrigation. In order to reduce conflicts which are linked to this situation, «Volumetric Management » introduces some new rules for irrigation practices including consultation. We propose to make a sociological assessment of the Volumetric Management basing on the notion of proximity with its different meanings. Several interviews with water users (farmers which use or don’t use water, fishers, residents, actors responsible for tourism… show that a new proximity due the share of organisation rules has been developed, but that this proximity is: asymmetric because it privileges links between partisans of irrigation; instrumental because it lacks a commune long-term vision of territorial development; at last partial because the different interdependencies induced by the same water resource are not considered.

    2018-06-01

    This study examined the relationship between ambient workplace heterosexism, emotional reactions (i.e., fear and anger), and outcomes for sexual minority and heterosexual employees. Five hundred thirty-six restaurant employees (68% female, 77% White) completed an online survey assessing the variables of interest. Results showed that greater experiences of ambient workplace heterosexism were associated with heightened fear and anger and, in turn, with heightened psychological distress (for fear) and greater physical health complaints, turnover intentions, and lowered job satisfaction (for anger). Fear also mediated the relationship between ambient workplace heterosexism and psychological distress. In addition, sexual orientation moderated the relationship between ambient workplace heterosexism and fear such that sexual minority employees reported more fear than heterosexuals with greater ambient heterosexism. These effects occurred after controlling for personal experiences of interpersonal discrimination. Our findings suggest that ambient workplace heterosexism can be harmful to all employees, not only sexual minorities or targeted individuals. Copyright © 2018 John Wiley & Sons, Ltd.

  15. The Potential for Ambient Plasma Wave Propulsion

    Science.gov (United States)

    Gilland, James H.; Williams, George J.

    2016-01-01

    A truly robust space exploration program will need to make use of in-situ resources as much as possible to make the endeavor affordable. Most space propulsion concepts are saddled with one fundamental burden; the propellant needed to produce momentum. The most advanced propulsion systems currently in use utilize electric and/or magnetic fields to accelerate ionized propellant. However, significant planetary exploration missions in the coming decades, such as the now canceled Jupiter Icy Moons Orbiter, are restricted by propellant mass and propulsion system lifetimes, using even the most optimistic projections of performance. These electric propulsion vehicles are inherently limited in flexibility at their final destination, due to propulsion system wear, propellant requirements, and the relatively low acceleration of the vehicle. A few concepts are able to utilize the environment around them to produce thrust: Solar or magnetic sails and, with certain restrictions, electrodynamic tethers. These concepts focus primarily on using the solar wind or ambient magnetic fields to generate thrust. Technically immature, quasi-propellantless alternatives lack either the sensitivity or the power to provide significant maneuvering. An additional resource to be considered is the ambient plasma and magnetic fields in solar and planetary magnetospheres. These environments, such as those around the Sun or Jupiter, have been shown to host a variety of plasma waves. Plasma wave propulsion takes advantage of an observed astrophysical and terrestrial phenomenon: Alfven waves. These are waves that propagate in the plasma and magnetic fields around and between planets and stars. The generation of Alfven waves in ambient magnetic and plasma fields to generate thrust is proposed as a truly propellantless propulsion system which may enable an entirely new matrix of exploration missions. Alfven waves are well known, transverse electromagnetic waves that propagate in magnetized plasmas at

    2010-09-01

    The authors assessed the relationship between exposure to ambient particulate matter and suicide in urban settings during a 1-year period. The association between particulate matter and suicide was determined using a time-stratified case-crossover approach in which subjects served as their own controls. All suicide cases (4,341) in 2004 that occurred in seven cities in the Republic of Korea were included. Hourly mean concentrations of particulate matter suicide risk associated with an interquartile range increase in particulate matter was determined by conditional logistic regression analysis after adjusting for national holidays and meteorological factors. Subgroup analysis was performed after stratification by underlying disease (cardiovascular disease, diabetes mellitus, chronic obstructive pulmonary disease, cancer, and psychiatric illness). The largest associations were a 9.0% increase (95% CI=2.4-16.1) and a 10.1% (95% CI=2.0-19.0) increase in suicide risk related to an interquartile range increase in particulate matter suicide) and particulate matter suicide), respectively. Among individuals with cardiovascular disease, a significant association between particulate matter suicide) and suicide was observed (18.9%; 95% CI=3.2-37.0). Conclusions: A transient increase in particulate matter was associated with increased suicide risk, especially for individuals with preexisting cardiovascular disease.

  20. A modified random decrement technique for modal identification from nonstationary ambient response data only

    International Nuclear Information System (INIS)

    Lin, Chang Sheng; Chiang, Dar Yun

    2012-01-01

    Modal identification is considered from response data of structural system under nonstationary ambient vibration. In a previous paper, we showed that by assuming the ambient excitation to be nonstationary white noise in the form of a product model, the nonstationary response signals can be converted into free-vibration data via the correlation technique. In the present paper, if the ambient excitation can be modeled as a nonstationary white noise in the form of a product model, then the nonstationary cross random decrement signatures of structural response evaluated at any fixed time instant are shown theoretically to be proportional to the nonstationary cross-correlation functions. The practical problem of insufficient data samples available for evaluating nonstationary random decrement signatures can be approximately resolved by first extracting the amplitude-modulating function from the response and then transforming the nonstationary responses into stationary ones. Modal-parameter identification can then be performed using the Ibrahim time-domain technique, which is effective at identifying closely spaced modes. The theory proposed can be further extended by using the filtering concept to cover the case of nonstationary color excitations. Numerical simulations confirm the validity of the proposed method for identification of modal parameters from nonstationary ambient response data

    2008-07-01

    Full Text Available En este artículo, se recogen las propuestas ético ambientales más importantes de la Escuela de Pensamiento Ambiental Latinoamericano, que ha ido construyéndose desde hace 30 años. Se destacan autores de primera línea en el campo de la construcción de Pensamiento Ambiental filosófico, como el Filósofo y Pensador Colombiano, de trascendencia latinoamericana, Augusto Ángel Maya, quien plantea la posibilidad de construir una Filosofía Ambiental Ético estética, dado que la Filosofía Moderna ha sido Metafísica, aún en sus corrientes empiristas, positivistas y neopositivistas. Se destaca la obra de Enrique Leff, mexicano, que propone los conceptos de Complejidad y Saber Ambiental, como puntos de partida de una ética en la educación, la ciencia y la tecnología, dentro de unas relaciones sistémicas y holísticas. Igualmente la propuesta ético estética compleja de Julio Carrizoza, colombiano, se hace presente en este ensayo, como una propuesta política fundamental ante problemas colombianos como son la violencia y la exclusión. Las propuestas de Filósofos colombianos de gran importancia en el campo de la Filosofía Política y Moral, que han desembocado en la propuesta de una Ética Ambiental, Pública y Comunicativa, como es el caso de Guillermo Hoyos Vásquez y de otros pensadores tanto de Colombia como de otros países latinoamericanos, se presentan en este espacio, con el fin de recoger de manera crítica nuestras ideas acerca de la posibilidad de una ética ambiental, es decir una ética descentrada, sin sujeto y sin objeto, una ética sistémica, donde los valores se construyen en las relaciones y donde la intricada trama de la vida, que ha venido construyéndose desde hace más de 2.500 millones de años, y de la cual somos meros hilos, pasa de ser objeto a ser valor primero en su más genuino sentido.

  2. Photocatalysts: ambient temperature destruction of VOCs

    Energy Technology Data Exchange (ETDEWEB)

    Miller, R [IT Corp., Oak Ridge, TN (United States)

    1994-12-31

    Photocatalysis was a failure as a solar energy driven organic synthesis technique, but as this study indicates, it has undergone a renaissance as a promising treatment method for volatile organic compounds (VOCs) in air streams. Photocatalytic oxidation (PCO) relies upon the ability of certain semiconductors to be stimulated by UV radiation. UV light excites valence band electrons in the semiconductor catalyst to jump to a conductance band leaving holes in the valence band. The electrons and holes can react with compounds such as organic contaminants present in an air stream. Hallmarks of the technology include rapid destruction kinetics for many VOCs at ambient temperature and efficient use energy in the form of UV-A photons. Studies clearly indicate that PCO is competitive on capital cost and offers significant operating cost savings on selected applications. 6 refs., 3 tabs., 2 figs.

    Ever since smoking was prohibited in restaurants, bars, and clubs, undesirable smells that were previously masked by cigarette smoke became noticeable. This opens up opportunities to improve the dance club environment by introducing pleasant ambient scents that mask the unwanted odors and to allow competing clubs to differentiate themselves. A field study was conducted at three dance clubs using a 3 × 3 Latin square design with pre- and post-measurements of no-scent control conditions. The three scents tested were orange, seawater, and peppermint. These scents were shown to enhance dancing activity and to improve the evaluation of the evening, the evaluation of the music, and the mood of the visitors over no added scent. However, no significant differences were found between the three scents.

    Monitoring vital signs through unobtrusive means is a goal which has attracted a lot of attention in the past decade. This review provides a systematic and comprehensive review over the current state of the field of ambient and unobtrusive cardiorespiratory monitoring. To this end, nine different sensing modalities which have been in the focus of current research activities are covered: capacitive electrocardiography, seismo- and ballistocardiography, reflective photoplethysmography (PPG) and PPG imaging, thermography, methods relying on laser or radar for distance-based measurements, video motion analysis, as well as methods using high-frequency electromagnetic fields. Current trends in these subfields are reviewed. Moreover, we systematically analyze similarities and differences between these methods with respect to the physiological and physical effects they sense as well as the resulting implications. Finally, future research trends for the field as a whole are identified.

    2013-11-01

    Full Text Available This paper introduces wireless sensor networks for Ambient Assisted Living as a proof of concept. Our workgroup has developed an arrhythmia detection algorithm that we evaluate in a closed space using a wireless sensor network to relay the information collected to where the information can be registered, monitored and analyzed to support medical decisions by healthcare providers. The prototype we developed is then evaluated using the TelosB platform. The proposed architecture considers very specific restrictions regarding the use of wireless sensor networks in clinical situations. The seamless integration of the system architecture enables both mobile node and network configuration, thus providing the versatile and robust characteristics necessary for real-time applications in medical situations. Likewise, this system architecture efficiently permits the different components of our proposed platform to interact efficiently within the parameters of this study.

    2017-01-01

    This book first introduces the background of spatial audio reproduction, with different types of audio content and for different types of playback systems. A literature study on the classical and emerging Primary Ambient Extraction (PAE) techniques is presented. The emerging techniques aim to improve the extraction performance and also enhance the robustness of PAE approaches in dealing with more complex signals encountered in practice. The in-depth theoretical study helps readers to understand the rationales behind these approaches. Extensive objective and subjective experiments validate the feasibility of applying PAE in spatial audio reproduction systems. These experimental results, together with some representative audio examples and MATLAB codes of the key algorithms, illustrate clearly the differences among various approaches and also help readers gain insights on selecting different approaches for different applications.

    Birmingham, J.G.; Hammerstrom, D.J.

    2000-02-01

    Atmospheric pressure nonthermal plasmas can efficiently deactivate bacteria in gases, liquids, and on surfaces, as well as can decompose hazardous chemicals. This paper focuses on the changes to bacterial spores and toxic biochemical compounds, such as mycotoxins, after their treatment in ambient pressure discharges. The ability of nonthermal plasmas to decompose toxic chemicals and deactivate hazardous biological materials has been applied to sterilizing medical instruments, ozonating water, and purifying air. In addition, the fast lysis of bacterial spores and other cells has led us to include plasma devices within pathogen detection instruments, where nucleic acids must be accessed. Decontaminating chemical and biological warfare materials from large, high value targets such as building surfaces, after a terrorist attack, are especially challenging. A large area plasma decontamination technology is described.
