  8. Environmental and economical feasibility of selective demolition project; Viabilidad ambiental y economica de un proyecto de demolicion selectiva: hacia una optima gestion de los RCD

    Energy Technology Data Exchange (ETDEWEB)

    Vegas, I.

    2004-07-01

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

    Full Text Available En se focalisant sur les politiques de gestion de l’eau, cet article aborde la question des usages sociaux de la frontière, de leur complexité et de leur ambiguïté ainsi que l’incidence de ces derniers sur la gouvernance du territoire transfrontalier. L’exemple de la plaine cerdane, à la frontière entre la France et l’Espagne, permet de distinguer plusieurs types d’usage de la frontière: un usage social pour légitimer le maintien de pratiques et un usage politique et institutionnel jouant sur les niveaux d’action publique. Malgré le volontarisme de certains acteurs, la gestion de l’eau peine à trouver une assise et un fonctionnement transfrontaliers. En effet, dès qu’elle menace de modifier les équilibres politiques économiques et sociaux existants, la gestion transfrontalière de l’eau est ainsi rapidement ramenée au Traité des Pyrénées et à l’hétérogénéité des situations nationales. Sur cette frontière, le cas retenu montre donc bien que les acteurs locaux ont un usage « à la carte » de leur situation frontalière en fonction des enjeux auxquels ils sont confrontés.By focusing on water management policies, this article addresses the social usage of borders, their complexity and ambiguity and how they impact the governance of cross-border territory. The case of the Cerdinyan plain on the French-Spanish border, allows distinguishing several types of border uses: a social usage to legitimate ongoing practices and a political and institutional use that capitalizes on levels of public action. In spite of the goodwill of certain actors, water management still has not found a solid cross-border base. As a matter of fact, water management is quickly assimilated to the Pyrenees Treaty and to the heterogeneity of national situations whenever it threatens to modify extant political, economic, and social balances. Along this border, the example chosen thus shows that local actors benefit from a

  16. Ambient Vibration Based Damage Diagnosis Using Statistical Modal Filtering and Genetic Algorithm: A Bridge Case Study

    Directory of Open Access Journals (Sweden)

    S. El-Ouafi Bahlous

    2013-01-01

    Full Text Available The authors recently developed a damage identification method which combines ambient vibration measurements and a Statistical Modal Filtering approach to predict the location and degree of damage. The method was then validated experimentally via ambient vibration tests conducted on full-scale reinforced concrete laboratory specimens. The main purpose of this paper is to demonstrate the feasibility of the identification method for a real bridge. An important challenge in this case is to overcome the absence of vibration measurements for the structure in its undamaged state which corresponds ideally to the reference state of the structure. The damage identification method is, therefore, modified to adapt it to the present situation where the intact state was not subjected to measurements. An additional refinement of the method consists of using a genetic algorithm to improve the computational efficiency of the damage localization method. This is particularly suited for a real case study where the number of damage parameters becomes significant. The damage diagnosis predictions suggest that the diagnosed bridge is damaged in four elements among a total of 168 elements with degrees of damage varying from 6% to 18%.

    The modification of traditional policies in nuclear business of Spanish Electrical Utilities, to meet new regulations is presented in this paper. It would be remarkable the influence of a new environment of significant economical transformation, which show us utilities affected by reorganization processes to face market demands. We will pay special attention to those activities involved in nuclear fuel management. Focusing in the field of Enriched Uranium supply, ENUSA, a state owned company, according to legal framework, played the role of sole supplier. The liberalization of primary energy sources was the turning point that triggered a process of changes. Now, the utilities rule the overall strategy and, not surprisingly they do definitively it is not. The new regulations tend to create conditions for a truly free market. So, competitiveness has become the magic word for almost all electricity producers. But in our case, the first question to be answered should be if free market does really mean a threat for us, or if it is just and external reference that puts no real pressure in our future plans. Lets remember that nuclear fuel cost in Spain is much lower than any other fuel cost. The working model we have defined is oriented to get benefit from market opportunities, improve flexibility and avoiding uncertainties in planning fuel cost strategy. (Author)

  1. Ambient temperature effects on gas turbine power plant: A case study in Iran

    International Nuclear Information System (INIS)

    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

    To investigate the effect of ambient air pollution on human health and the subsequent disability-adjusted life years (DALYs) lost in Shanghai. Methods We used epidemiology-based exposure-response functions to calculate the attributable number of cases due to air pollution in Shanghai in 2000, and then we estimated the corresponding DALYs lost in Shanghai based on unit DALYs values of the health consequences. Results Ambient air pollution caused 103 064 DALYs lost in Shanghai in 2000. Among all the health endpoints, premature deaths and chronic bronchitis predominated in the value of total DALYs lost. Conclusion The air pollution levels have an adverse effect on the general population health and strengthen the rationale for limiting the levels of air pollution in outdoor air in Shanghai.

    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.

    Christine N. Manser

    2012-04-01

    Full Text Available Despite the increasing use of carbon dioxide for endoscopies during the last years, ambient air is still used. The amount of air depends on several factors such as examination time, presumable diameter of the endoscope channel and of course active use of air by the operator. Although endoscopic complications due to ambient air in the gastrointestinal (GI tract are a rare observation and mostly described in the colon, we report five cases in the upper GI tract due to insufflating large amounts of air through the endoscopes. All 5 patients needed an emergency upper endoscopy for acute presumed upper GI bleeding. In two cases both esophageal variceal bleeding and ulcer bleeding were detected; the fifth case presented with a bleeding due to gastric cancer. Due to insufflation of inadequate amounts of air through the endoscope channel, all patients deteriorated in circulation and ventilation. Two rumenocenteses and consecutively three laparotomies had to be performed in three patients. In the other two, gastroscopies had to be stopped for an emergency computed tomography. All critical incidents were believed to be a consequence of a long-lasting examination with use of too much air. Therefore in emergency situations, endoscopies should be performed with either submersion, low air flow pumps or even better by the use of carbon dioxide.

    Full Text Available This study highlights the variation values of several important microclimatic parameters inside an office building. This way, duringone year time period, from February 2010 to February 2011,, we have recorded the natural wet temperature, the predicted mean vote–PMV, the predicted percent of dissatisfied people–PPD,WBGT indoor,WBGT outdoor, the draught risk, the luminous intensity and the sound level. Then, we could calculate the monthly, daily and hourly variation of these microclimatic and ambient comfort parameters. The recordings of the data were made by means of a microclimatic indoor station, a sound level meter and a light meter. The results helped usunderstand better how the values of these microclimatic parameters may influence the working conditions inside an office building, if the microclimate is one of thermal comfort or discomfort, or if it is beneficial or harmful to the development in good conditions of working activities within collective environments.

    An extension of the matter-element method was applied to estimate ambient air quality in Haizhou opencast colliery in Fuxin coal mine. Air pollutants data such as sulphur dioxide, carbon monoxide, nitrogen oxides, total suspended particulates, particulate matter and dustfall were collected at four different air-quality monitoring stations located in four districts around the Fuxin colliery. Results show that total suspended particulates, particulate matter <10 {mu}m, dustfall and sulphur dioxide were the predominant pollutants. Other pollutants such as carbon monoxide and nitrogen oxides were also detected at the Fuxin colliery. Air pollution came mainly from industrial emissions, mining activities and abandoned gangue stockpiles (mine tailings). Compared to those applied to other mathematical assessment methods, it was demonstrated that the extension of the matter-element model was quite appropriate for air quality assessment.

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

    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.

    Full Text Available A partir do início da década de 2000 o estado do Rio de Janeiro passou a conviver com um conjunto de investimentos sem precedentes na sua história. Esses investimentos estão marcados pelo peso da siderurgia e da indústria de óleo e gás natural, com importante participação das atividades portuárias, de densas redes de dutos e da indústria naval. O conjunto de atividades e redes logísticas resultantes condiciona o dinamismo de distintas regiões do estado, especialmente da Zona Costeira. As avaliações feitas a propósito focam, mais freqüentemente, os resultados que esses investimentos estão (ou estarão gerando no que se refere ao “(reaquecimento da economia fluminense”. Contudo, existem outros observadores preocupados com os efeitos desses investimentos em termos de (reordenamento e desenvolvimento do território. Algumas dessas preocupações estão associadas à baixa capacidade de resposta demonstrada pelo Poder Público - sobretudo pelos governos locais - quando confrontado com cenários fortemente condicionados por decisões empresariais formuladas por um pequeno número de grandes corporações, como no caso da área de influência do porto de Itaguaí.

    End-user development is a new trend to provide tailored services to dynamic environments such as hospitals. These services not only facilitate daily work for pharmacy personnel but also improve self-care in elder people that are still related to hospital, such as discharged patients. This paper presents an ambient intelligence (AmI) environment for End-user service provisioning in the pharmacy department of Gregorio Marañón Hospital in Madrid, composed of a drug traceability infrastructure (DP-TraIN) and a ubiquitous application for enabling the pharmacy staff to create and execute their own services for facilitating drug management and dispensing. The authors carried out a case study with various experiments where different roles from the pharmacy department of Gregorio Marañón Hospital were involved in activities such as drug identification, dispensing and medication administering. The authors analyzed the effort required to create services by pharmacy staff, the discharged patients' perception of the AmI environment and the quantifiable benefits in reducing patient waiting time for drug dispensing.

    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.

  19. Contribution of ambient ozone to Scots pine defoliation and reduced growth in the Central European forests: A Lithuanian case study

    International Nuclear Information System (INIS)

    The study aimed to explore if changes in crown defoliation and stem growth of Scots pines (Pinus sylvestris L.) could be related to changes in ambient ozone (O3) concentration in central Europe. To meet this objective the study was performed in 3 Lithuanian national parks, close to the ICP integrated monitoring stations from which data on meteorology and pollution were provided. Contribution of peak O3 concentrations to the integrated impact of acidifying compounds and meteorological parameters on pine stem growth was found to be more significant than its contribution to the integrated impact of acidifying compounds and meteorological parameters on pine defoliation. Findings of the study provide statistical evidence that peak concentrations of ambient O3 can have a negative impact on pine tree crown defoliation and stem growth reduction under field conditions in central and northeastern Europe where the AOT40 values for forests are commonly below their phytotoxic levels. - Peak ozone concentrations is one of the key factors affecting Scots pine trees

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.

    2006-08-01

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

    Venturi easy ambient sonic spray ionization mass spectrometry in both its liquid (V(L) -EASI-MS) and solid sample modes (V(S) -EASI-MS) is shown to provide nearly immediate and secure typification of woods, as demonstrated for Mahogany, an endangered and most valuable type of tropical wood. This reddish wood displays unique phytochemical markers (phragmalin-type limonoids) which are rapidly detected from the wood surface by V(S) -EASI-MS or from a simple methanol extract of a tiny wood chip by V(L) -EASI-MS. Unique profiles were obtained for Mahogany (Swietenia macrophylla) whereas genuine samples of six other similar types of woods, which are commonly falsified by artificial coloring and commercialized as Mahogany, display also typical but dissimilar pythochemical profiles as compared to that of the authentic wood. Variable and atypical chemical profiles were observed for artificially colored woods. Secure chemical characterization via V(S) -EASI-MS or V(s) -EASI-MS fingerprints of Mahogany and other types of woods with similar appearance should help to control the illegal logging and trade of this and other endangered woods and their falsification, and to create certified standards.

    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.

  15. Diesel emissions significantly influence composition and mutagenicity of ambient particles: a case study in Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    In 2003, a bus strike paralyzed the fleet of buses in Sao Paulo, Brazil during 3 days, from 6 to 8 of April, the complete interruption of services being achieved on the 7th. We evaluated the effect of the absence of this source of pollution on the composition, mutagenicity, and toxicity of the fine particulate material collected during this period. Particles were sampled in glass fiber filters on days 7 and 15 of April of 2003 (strike and nonstrike days, respectively), using a high-volume sampler. Trace element determinations (As, Br, Co, Cl, Fe, La, Mn, Sb, Sc, and Th) of particulate material samples were carried out by neutron activation analysis. Sulfur determination was done by X-ray fluorescence analysis. The ratio between nonstrike/strike concentrations of hydrocarbons associated with automotive emissions (benzene, toluene, ethyl-benzene, and xylenes; BTEX) was determined by gas chromatography/mass spectrometry. Mutagenesis of testing solutions was determined by means of the Tradescantia micronucleus assay in early tetrads of Tradescantia pallida. The inhibition of mitosis of the cells of the primary meristema of the root tips of Allium cepa was used as an index of the toxicity. Fine particle trace element contents were lower during the strike. The concentrations of sulfur and BTEX were 50% and 39.3% lower, respectively, on the strike day. A significant (P=0.038) reduction of micronuclei induced by fine particles sampled during the strike was observed. No effect of the strike on toxicity was detected. These results indicate that a program aiming to reduce emissions of the bus fleet in our town may impact positively the air quality by reducing the mutagenic potential of ambient particles

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

    Full Text Available One of the main aims of the study was an experimental determination of the conversion coefficient from ambient dose equivalent rate, Н*(10, to absorbed dose rate in air, D, in the case of radioactive contamination of the environment following the Chernobyl accident. More than 800 measurements of gamma-dose rates in air were performed at the typical locations (one-storey residential house, street, yard, kitchen-garden, ploughed field, undisturbed grassland, forest of rural settlements and their surroundings in the heavily contaminated areas of the Bryansk region, Russia in the period of 1996–2010. Five commercially available models of portable gamma-ray dosimeters were employed in the investigation. All tested dosimeters were included into the State register of approved measuring instruments of Russia. In all dosimeters, scintillation detectors are used as detection elements. A photon spectrometry technique is applied in the dosimeters to determine gamma dose rate in air. The dosimeters are calibrated in terms of exposure rate, X, absorbed dose rate in air, D, and ambient dose equivalent rate, Н*(10. A very good agreement was found between different dosimeters calibrated in the same units; the reading ratios were close to 1 and the correlation coefficients (Pearson’s or Spearman’s were higher than 0.99. The Н*(10/D ratio values were location-specific ranging from 1.23 Sv/Gy for undisturbed grasslands and forests to 1.47 Sv/Gy for wooden houses and asphalted streets. A statistically significant negative correlation (Spearman’s coefficient = -0.833; P<0.01; n=9 was found between the Н*(10/D ratio and the average energy of gamma-rays determined with a NaI(Tl-based gamma-ray monitor. For the whole area of a settlement and its surroundings, the average ratio of Н*(10 to D was calculated as 1.33 Sv/Gy. The overall conversion coefficient from ambient dose equivalent rate, Н*(10, to external effective dose rate, Ė, for adults was estimated

    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.

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.

A metodologia adotada é um estudo de caso em um hospital, utilizando-se de uma entrevista semi- estrutura da com o responsável pela área ambiental da instituição. A trajetória metodológica divide-se em três fases, sendo a primeira: fundamentação teórica do meio ambiente, gestão ambiental, auditoria, contabilidade e controladoria ambiental. A segunda fase envolve o estudo de caso, onde são realizadas primeira mente as entrevistas com base em uma lista de verificação, divididas em critérios e subcritérios. Na terceira e última fase apresenta-se análise dos resultados; a sustentabilidade parcial e total, bem como o planejamento 5W2H. No final, como resultado da pesquisa, verificou-se uma sustentabilidade global de 70,83%, considerada “regular”. Existem pontos fortes e fracos na gestão do meio ambiente, mas no geral ela apenas cumpre com a legislação.The current environmental destruction is the result of the unlimited use of naturalresources by our society. Because of that, the government has been demanding a moreresponsible policy from the organizations.

  1. Atmosphere and Ambient Space

    DEFF Research Database (Denmark)

    Schmidt, Ulrik

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

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

  3. Correction of phase velocity bias caused by strong directional noise sources in high-frequency ambient noise tomography: a case study in Karamay, China

    We collect two months of ambient noise data recorded by 35 broad-band seismic stations in a 9 × 11 km area (1-3 km station interval) near Karamay, China, and do cross-correlation of noise data between all station pairs. Array beamforming analysis of the ambient noise data shows that ambient noise sources are unevenly distributed and the most energetic ambient noise mainly comes from azimuths of 40°-70°. As a consequence of the strong directional noise sources, surface wave components of the cross-correlations at 1-5 Hz show clearly azimuthal dependence, and direct dispersion measurements from cross-correlations are strongly biased by the dominant noise energy. This bias renders that the dispersion measurements from cross-correlations do not accurately reflect the interstation velocities of surface waves propagating directly from one station to the other, that is, the cross-correlation functions do not retrieve empirical Green's functions accurately. To correct the bias caused by unevenly distributed noise sources, we adopt an iterative inversion procedure. The iterative inversion procedure, based on plane-wave modeling, includes three steps: (1) surface wave tomography, (2) estimation of ambient noise energy and biases and (3) phase velocities correction. First, we use synthesized data to test the efficiency and stability of the iterative procedure for both homogeneous and heterogeneous media. The testing results show that: (1) the amplitudes of phase velocity bias caused by directional noise sources are significant, reaching ˜2 and ˜10 per cent for homogeneous and heterogeneous media, respectively; (2) phase velocity bias can be corrected by the iterative inversion procedure and the convergence of inversion depends on the starting phase velocity map and the complexity of the media. By applying the iterative approach to the real data in Karamay, we further show that phase velocity maps converge after 10 iterations and the phase velocity maps obtained using

Cette lecture montre cependant que les objectifs, les ressources et les stratégies des principaux acteurs concernés sont difficilement conciliables et que le système de relation qu’il induit n’est pas nécessairement en phase avec les finalités poursuivies.Marked by exceptional biodiversity and extreme human poverty, Madagascar is experiencing a rapid destruction of its natural resources, placing territory and its appropriation at the heart of development issues. From this perspective, this article will look at the development and implementation of a public policy, the Gestion LOcale SÉcurisée (GELOSE, for the local management of natural renewable resources. This regulation seeks to transfer the management of these resources from the government to local communities in the goal of protecting them more effectively. We will see, however, that the objectives, resources and strategies of the primary actors concerned are difficult to reconcile at best and that the relational system to which the policy gives rise is not necessarily in keeping with the goals being pursued.

    2011-08-01

    Full Text Available Baseado na discussão entre tornar o disclosure ambiental obrigatório ou não, o objetivo desta pesquisa foi verificar se as práticas de evidenciação ambiental das companhias analisadas reagem aos distintos estímulos regulatórios de seus países de origem. A resposta desta pergunta é útil no sentido de determinar a eficácia da introdução de mecanismos regulatórios nas práticas de evidenciação ambiental. Uma vez que o disclosure ambiental é, predominantemente, voluntário as companhias podem simplesmente suplantar a regulação, tornando-a sem sentido. Para o desenho metodológico, optou-se por uma abordagem descritiva de cunho predominantemente quantitativo. A amostra foi selecionada de empresas do setor de petróleo e gás natural de quatro países com similaridades culturais: os Estados Unidos, o Canadá, a Inglaterra e a Austrália. Os dados analisados foram coletados nos relatórios anuais no ano de 2007. Para classificar os dados ambientais utilizou-se uma escala adaptada de dois trabalhos consagrados no meio da evidenciação ambiental, o estudo de Clarkson et al. (2008 e o de Wiseman (1982. O teste estatístico (teste H comprovou que existem diferenças significativas entre os níveis de evidenciação ambiental das companhias da amostra pertencentes aos países mais regulados em comparação com os menos regulados e essas diferenças só foram significativas nos itens de divulgação obrigatória, o que comprova que o disclosure ambiental das companhias reage aos estímulos regulatórios de seus países.Based on different opinions concerning the need for mandatory environmental disclosure, the main purpose of this research was to verify whether or not the company's environmental reporting practices react to different regulatory stimuli.

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

  5. Comparison of ground truth location of earthquake from InSAR and from ambient seismic noise: A case study of the 1998 Zhangbei earthquake

    Science.gov (United States)

    Xie, Jun; Zeng, Xiangfang; Chen, Weiwen; Zhan, Zhongwen

    2011-04-01

    Because ambient seismic noise provides estimated Green's function (EGF) between two sites with high accuracy, Rayleigh wave propagation along the path connecting the two sites is well resolved. Therefore, earthquakes which are close to one seismic station can be well located with calibration extracting from EGF. We test two algorithms in locating the 1998 Zhangbei earthquake, one algorithm is waveform-based, and the other is traveltime-based. We first compute EGF between station ZHB (a station about 40 km away from the epicenter) and five IC/IRIS stations. With the waveform-based approach, we calculate 1D synthetic single-force Green's functions between ZHB and other four stations, and obtain traveltime corrections by correlating synthetic Green's functions with EGFs in period band of 10-30 s. Then we locate the earthquake by minimizing the differential travel times between observed earthquake waveform and the 1D synthetic earthquake waveforms computed with focal mechanism provided by Global CMT after traveltime correction from EGFs. This waveform-based approach yields a location which error is about 13 km away from the location observed with InSAR. With the traveltime-based approach, we begin with measuring group velocity from EGFs as well as group arrival time on observed earthquake waveforms, and then locate the earthquake by minimizing the difference between observed group arrival time and arrival time measured on EGFs. This traveltime-based approach yields accuracy of 3 km, Therefore it is feasible to achieve GT5 (ground truth location with accuracy 5 km) with ambient seismic noises. The less accuracy of the waveform-based approach was mainly caused by uncertainty of focal mechanism.

  3. Low shear velocity in a normal fault system imaged by ambient noise cross correlation: The case of the Irpinia fault zone, Southern Italy

    Vassallo, Maurizio; Festa, Gaetano; Bobbio, Antonella; Serra, Marcello

    2016-06-01

    We extracted the Green's functions from cross correlation of ambient noise recorded at broadband stations located across the Apennine belt, Southern Italy. Continuous records at 26 seismic stations acquired for 3 years were analyzed. We found the emergence of surface waves in the whole range of the investigated distances (10-140 km) with energy confined in the frequency band 0.04-0.09 Hz. This phase reproduces Rayleigh waves generated by earthquakes in the same frequency range. Arrival time of Rayleigh waves was picked at all the couples of stations to obtain the average group velocity along the path connecting the two stations. The picks were inverted in separated frequency bands to get group velocity maps then used to obtain an S wave velocity model. Penetration depth of the model ranges between 12 and 25 km, depending on the velocity values and on the depth of the interfaces, here associated to strong velocity gradients. We found a low-velocity anomaly in the region bounded by the two main faults that generated the 1980, M 6.9 Irpinia earthquake. A second anomaly was retrieved in the southeast part of the region and can be ascribed to a reminiscence of the Adria slab under the Apennine Chain.

    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

  6. Ambient oxygen promotes tumorigenesis.

    Directory of Open Access Journals (Sweden)

    Ho Joong Sung

    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.

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

    Science.gov (United States)

    Auld, Tony D.; Keith, David A.; Hui, Francis K. C.; Ooi, Mark K. J.

    2016-01-01

    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

    Ambient monitors are commonly used to estimate exposure for epidemiological studies, and air quality modeling is infrequently applied. However air quality modeling systems have the potential to alleviate some, although not all, of the limitations of monitoring networks. To investigate this application, exposure estimates were generated for a case study high ozone episode in the Northern Georgia Region of the United States based on measurements and concentration estimates from an air quality modeling system. Hourly estimates for 2268 4-km by 4-km gridcells were generated in a domain that includes only eight ozone monitors. Individual and population-based ozone exposures were estimated using multiple approaches, including area-weighted average of modeled estimates, nearest monitor, and spatial interpolation by inverse distance weighting and kriging. Results based on concentration fields from the air quality modeling system revealed spatial heterogeneity that was obscured by approaches based on the monitoring network. With some techniques, such as spatial interpolation, monitoring data alone was insufficient to estimate exposure for certain areas, especially for rural populations. For locations far from ozone monitors, the estimates from the nearest monitor approach tended to overestimate exposure, compared to modeled estimates. Counties in which one or more monitors were present had statistically higher population density and modeled ozone estimates than did counties without monitors (p-value <0.05). This work demonstrates the use of air quality modeling to generate higher spatial and temporal resolution exposure estimates, and compares the advantages of this approach to traditional methods that use monitoring data alone. The air quality modeling method faces its own limitations, such as the need to thoroughly evaluate concentration estimates and the use of ambient levels rather than personal exposure. PMID:16516968

  15. The influence of ambient light on the driver

    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.

    Full Text Available Ten years after their creation, the operation of the community-based natural resource management policy named ‘transfert de gestion’ – the 1996 GELOSE law (applied to any kind of natural resources, and the 2001 GCF decree (only applied to forests – remains little understood. The forest corridor linking Ranomafana and Andringitra National Parks has been extended south, and since 2006 the Fandriana-Vondrozo Corridor has been established as a new protected area within the Madagascar Protected Area System. Eighty-two sites of transfert de gestion have been created since 2001 in the Fandriana-Vondrozo Corridor and Randriamahaleo III are managed by local community associations named COBA. Management is determined by law but is locally adapted to each site. We analyze the dynamic of the community forest management system using six variables and 19 modes: year of creation (five modes, legal form of management (two modes, locality (two modes, principal NGO partners (five modes, management objective (two modes, and surface area of the transferred site (three modes. There are four institutions in charge of forest management: local community associations (COBA, which manage the forest in their territory; the Forest Service (Eaux et Forêt representing the State, which controls this management; the commune, the smallest decentralized unit of the State, which manages the whole communal territory including forests; and NGOs, which facilitate the process. In order to investigate institutional tendencies, the sites of transfert de gestion are analyzed using Multiple Correspondence Analysis. The sites are distributed in the first two factorial plans with percentage variance of 18.5 % and 15.8 % according to their objectives: 1 pure conservation, and 2 economic development. Three types of NGO are distinguished by the form and duration of their support to COBA. The NGOs with greatest weight in the process are those which support the transfert de gestion

    1990-12-01

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

  6. Smooth bumps in H/V curves over a broad area from single-station ambient noise recordings are meaningful and reveal the importance of Q in array processing: The Boumerdes (Algeria) case

    Science.gov (United States)

    Guillier, B.; Chatelain, J.-L.; Hellel, M.; Machane, D.; Mezouer, N.; Ben Salem, R.; Oubaiche, E. H.

    2005-12-01

    Single-station H/V curves from ambient noise recordings in Boumerdes (Algeria) show smooth bumps around 1 and 3 Hz. A complementary microtremor study, based on two 34 and 134-meter aperture arrays, evidences that these bumps are indeed real peaks produced by two strong VS contrasts at 37 and 118 meters depth, strongly smoothed by very high S-wave attenuation in the two sedimentary layers. These two H/V bumps, observed over a broad area, are meaningful and reveal the importance of Q in S-wave velocity modeling from microtremor array data processing. It also appears that Tertiary rocks should be, at least in some cases, taken into account, together with the Quaternary sediments, to explain single-station H/V frequency peaks, and therefore that considering only the first 30 m of soil for VS amplification evaluation, as usually recommended, sometimes leads to flaky results by artificially eliminating non-explained low-frequency peaks from the analysis.

L’article rappelle, tout d’abord, que ces dispositifs, généralement importés des États-Unis, prétendent accroître la compétitivité des entreprises, en s’appuyant sur des critères réputés universels.Cependant, au Brésil, les modèles de gestion mondialisés sont mis en œuvre par les directions qui se saisissent de leurs potentialités pour intensifier le processus de domination dans les relations capital-travail. En effet, les formes de gestion sont renouvelées pour essayer d’obtenir des téléopérateurs l’intériorisation partielle des normes de travail, en rendant opérationnel le contrôle gestionnaire ancré dans la technologie. L’article suggère que le système de management « au corps à corps » s’appuye également sur la fragilité des salariées, prises dans les effets conjugués d’un fort taux de chômage et des rapports sociaux de genre.The question of the encounter between imported management arrangements and socio-historical configurations is examined in the case of Brazilian call centres. The article first of all recalls that these arrangements, generally imported from the United States, claim to increase the companies’ competitiveness, in basing themselves on criteria deemed universal.Yet, in Brazil, the globalized management models are put to work by directors wanting to grasp their potentials for intensifying their domination processes in capital-labour relationships. In effect, these management forms have been renewed to try and instill in tele-operators a partisan interiorization of work standards, by applying an adminstrative and management control anchored in technology. The article suggests that this “hand to hand” system of management also has an effect on the fragility level of salaried workers, caught up in the

    2010-01-01

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

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

Cet article 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. This paper intends to give an overview on four countries known to have established national parks for over a century, and often in clearing the land from previous ‘indigenous’ or local occupation. Since the seventies, public participation has become a common practice in parks’ management, even if reality does not fit always perfectly with theory. The paper analyses general trends of public participation in parks management practices, which are most often considered as a successful governance policies by most authors, and is also considered as a way to build participative democracy. The analysis using the level of scale intends to show that public participation can also fragment the stakeholders, making really difficult the emergence of any efficient coalition of

  9. Anisotropic Ambient Volume Shading.

    Ament, Marco; Dachsbacher, Carsten

    2016-01-01

    We present a novel method to compute anisotropic shading for direct volume rendering to improve the perception of the orientation and shape of surface-like structures. We determine the scale-aware anisotropy of a shading point by analyzing its ambient region. We sample adjacent points with similar scalar values to perform a principal component analysis by computing the eigenvectors and eigenvalues of the covariance matrix. In particular, we estimate the tangent directions, which serve as the tangent frame for anisotropic bidirectional reflectance distribution functions. Moreover, we exploit the ratio of the eigenvalues to measure the magnitude of the anisotropy at each shading point. Altogether, this allows us to model a data-driven, smooth transition from isotropic to strongly anisotropic volume shading. In this way, the shape of volumetric features can be enhanced significantly by aligning specular highlights along the principal direction of anisotropy. Our algorithm is independent of the transfer function, which allows us to compute all shading parameters once and store them with the data set. We integrated our method in a GPU-based volume renderer, which offers interactive control of the transfer function, light source positions, and viewpoint. Our results demonstrate the benefit of anisotropic shading for visualization to achieve data-driven local illumination for improved perception compared to isotropic shading. PMID:26529745

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

Le cas d’étude est celui d’une zone d’ancienne industrialisation en reconversion – le bassin minier du Nord – Pas de Calais – soumise à un passif environnemental spécifique. Nous tentons de montrer que l’incertitude inhérente aux externalités induit, en premier lieu, une certaine faiblesse des proximités organisées, puis la construction de formes de proximités particulières, passant par des dispositifs régulatoires innovants. Le contenu de ces proximités, leur efficacité, leur lien avec la dynamique économique territoriale, sont analysés successivement.Managing the environmental externalities of the Nord – Pas de Calais coal field : a tentative approach in terms of proximity. The purpose of this article is to explore how the conceptual categories used in the proximity approach can be applied to such issues as the management of environmental externalities. The case study is the Nord – Pas de Calais coal field, a formerly industrial area. Consequently, we focus on the specific environmental damages in this area which is currently undergoing reconversion. The aim of this paper is to show that the uncertainty which is inherent to externalities induces some degree of weakness on the part of “organised proximities” at first, then the setting-up of specific forms of proximity via innovative regulatory tools. The contents of those proximities, their efficiency and their relevance to the local economic dynamics will be analysed successively.

    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.

    The ambient calculus is a calculus of computation that allows active processes (mobile ambients) to move between sites. A firewall is said to be protective whenever it denies entry to attackers not possessing the required passwords. We devise a polynomial time algorithm for rejecting proposed...... firewalls that are not guaranteed to be protective. This is based on a control flow analysis for recording what processes may turn up inside what other processes; in particular, we develop a syntax-directed system for specifying the acceptability of an analysis, we prove that all acceptable analyses are...... semantically sound, and we demonstrate that each process admits a least analysis....

  4. Ambient cosmology and spacetime singularities

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

    Full Text Available La existencia de la ciencia ambiental es reconocida en libros, revistas de publicación científica y carreras de grado y posgrado. Sin embargo, se desconoce su existencia en forma literal o indirecta, al no ser considerado su aporte, por ejemplo, en los planteos referidos sobre la ciencia y la tecnología de la sustentabilidad. En este trabajo se presentan estos antecedentes, relacionándolos con el objetivo del mismo, que es el de aportar a la dilucidación de la existencia y conformación de la ciencia ambiental. Para esto, se analiza la relación de las disciplinas con la dimensión compleja del ambiente como objeto de estudio y aspectos metodológicos derivados. A los fines de aportar al esclarecimiento conceptual, se identifican las distintas acepciones de ambiente comúnmente referidas en la bibliografía. Además, se discuten aspectos relacionados de multidisciplinariedad, interdisciplinariedad y transdisciplinariedad, y sobre el status epistémico de la ciencia ambiental. Se concluye que una mayor precisión conceptual embasada en un marco compartido por las disciplinas que estudian el ambiente, incluida la ciencia ambiental, y los distintos actores involucrados en las problemáticas ambientales, favorecerá el refinamiento de las metodologías tendientes a disminuir la fragmentación de las investigaciones concernientes y las aplicaciones para su resolución.The existence of an environmental science is recognized in books, journals of science as well as in undergraduate and graduate studies. Its existence, however, is unknown either literally or indirectly when, for instance, its contribution to topics connected to the science and technology of sustainability is not considered.

    2012-01-01

    Full Text Available Charles III duc de Savoie se retrouve après une série de défaites contre les Bernois et contre François I pratiquement dépouillé de ses Etats. A sa mort en 1553 il n’est plus maître que de Nice et de Verceil dans le nord du Piémont. L’Etat savoyard est sur le point de disparaître. La difficile succession revient à son fils Emmanuel Philibert. Le nouveau duc est alors lieutenant de Philippe II dans la guerre qu’il mène contre les Français. Le 10  août 1557 il gagne une bataille décisive à Saint-Quentin. La paix du Cateau-Cambrésis qui clôt cette guerre en 1559 permet à Emmanuel Philibert de recouvrer ses Etats. C’est avec une ambition nouvelle que le duc reprend le pouvoir. Il rêve de bâtir un Etat moderne et efficace pour servir une diplomatie ambitieuse. Celle-ci passe par une présence sur la scène méditerranéenne occidentale où se déroule depuis le début du siècle un conflit majeur entre les puissances chrétiennes et l’Empire ottoman. Les incidents sont permanents et chaque campagne annuelle se termine par une formidable bataille navale opposant  deux voire trois cents galères. Année après année les Turcs progressent. Le duc souhaite mettre son poids de puissance moyenne dans la balance et devenir ainsi un allié privilégié de l’Espagne. Pour cela il lui faut des galères et un port bien protégé pour les abriter. C’est-à-dire beaucoup d’argent. La rénovation fiscale qu’il entreprend et une bonne gestion des droits indirects permettront de faire cet effort. Le budget des galères occupe ainsi une place non négligeable dans les finances de l’Etat. Autant dire que le poste est surveillé. Préoccupation centrale du duc la gestion des galères doit être sans défaut.Les comptes des galères permettent de juger cette gestion pendant un demi siècle, sous Emmanuel Philibert d’abord puis sous le règne de son fils Charles Emmanuel I (1580-1630.

Avaliaram-se a concentração de dióxido de carbono, a vazão e renovação de ar nas salas do centro cirúrgico. A concentração de bioaerossóis foi estimada em um dia de avaliação para cada ambiente. Não se observou relação entre a concentração de bioaerossóis e o tempo de uso das salas de cirurgia. A concentração média de bioaerossóis foi de 231 UFC.m-3 para fungos e de 187 UFC.m-3 para bactérias. Os ambientes avaliados atendiam aos valores recomendados pela legislação vigente. Os resultados permitiram avaliar criticamente essa legislação e apresentar sugestões para estabelecimento de uma resolução específica para ambientes hospitalares no Brasil.The objective of this paper was to evaluate the air quality in three indoor hospital environments: a neonatal intensive care unit (ICU, an adult ICU and a surgical ward of a hospital in Florianópolis, Brazil. Carbon dioxide concentrations, exchange air flow rates as well as fungi and bacteria concentrations were measured in these rooms. Bioaerosol concentrations were evaluated throughout one-work day for each operating room. No relationship was observed between bioaerosol concentration and the period of use in the surgical ward. Average bioaerosol concentrations were of 231 UFC.m-3 for filamentous fungi and 187 UFC.m-3 for bacteria. All environments evaluated were, overall, in compliance with current legislations. Results allowed a critical review of the present regulations and suggestions for the establishment of a specific regulation for hospital environments in Brazil.

    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

Même si les unités pastorales de gestion des ressources ont prouvé leur intérêt dans plusieurs cas de la première phase du projet en zone pastorale, il semble que dans le contexte sénégalais actuel de politique sectorielle agricole, et d’accaparement privé des ressources foncières, la généralisation systématique du schéma des UP sur tout le territoire risquerait plutôt de menacer la durabilité de la mobilité pastorale.In Ferlo (Senegalese Sahel, the sustainability of the livestock farming depends on the diversity and the flexibility of the regulations of mobility.

    Full Text Available La situation actuelle des ressources en eau et de leurs usages dans le Sud-Est tunisien présente des enjeux qui sont communs à de nombreuses régions du bassin méditerranéen : des ressources limitées et déjà largement exploitées pour répondre à la croissance des besoins, le recours accru aux ressources dites non conventionnelles, une situation de concurrence entre usages sectoriels, une marchandisation croissante des ressources, et des conditions climatiques contraignantes qui viennent renforcer les tensions autour de l'eau. Dans le contexte des mutations en cours, face aux risques de déficits en eau et à la nécessité d'un développement économique et social équilibré, ces caractéristiques, parmi d'autres, font de la Jeffara tunisienne un cas d'étude exemplaire des difficultés que pose la gestion intégrée de l'eau. Celle-ci doit prendre en compte les différentes sources d'approvisionnement ainsi que les différents usages associés, et donc l'identification des territoires pertinents pour cette  gestion, compte tenu des relations amont-aval naturelles et artificielles d'une part, et des cohérences institutionnelles et sociales d'autre part.The current situation of the water resources and their uses in South-Eastern Tunisia presents stakes which are common to many areas of the Mediterranean basin : limited and already largely exploited resources to address the growth of the needs, the increasing use of so-called non conventional resources, a competition between sectoral uses of water, an increasing merchandising of the resources, and constraining climatic conditions which reinforce the tensions around water. In the context of the changes in progress, facing the hazard of water deficits and with the need for a balanced economic and social development, these characteristics, among others, make Tunisian Jeffara be an exemplary case of study of the difficulties raised by the integrated water resources management.

    Despite its fundamental importance, physical mechanisms that govern friction are poorly understood. While a state of ultra-low friction, termed structural lubricity, is expected for any clean, atomically flat interface consisting of two different materials with incommensurate structures, some associated predictions could only be quantitatively confirmed under ultra-high vacuum (UHV) conditions so far. Here, we report structurally lubric sliding under ambient conditions at mesoscopic (∼4,000–130,000 nm2) interfaces formed by gold islands on graphite. Ab initio calculations reveal that the gold–graphite interface is expected to remain largely free from contaminant molecules, leading to structurally lubric sliding. The experiments reported here demonstrate the potential for practical lubrication schemes for micro- and nano-electromechanical systems, which would mainly rely on an atomic-scale structural mismatch between the slider and substrate components, via the utilization of material systems featuring clean, atomically flat interfaces under ambient conditions.

    A pressure chamber is designed to study the crumpling process under an ambient force. The compression force and its resulting radius for the ball obey a power law with an exponent that is independent of the thickness and initial size of the sheet. However, the exponent is found to be material-dependent and less than the universal value, 0.25, claimed by the previous simulations. The power law behavior disappears at high pressure when the compressibility drops discontinuously, which is suggest...

Na primeira parte, será analisado como este fenômeno, somado a mudança do uso do solo urbano resultou no surgimento das áreas de risco, uma vez que as áreas contaminadas estão sendo utilizadas ou receberam novos usos, como residenciais ou serviços, sem que fossem realizados estudos ambientais específicos com posterior recuperação e/ou remediação. Com o objetivo de auxiliar no entendimento, abrangência e magnitude da questão, será apresentado um mapeamento, por distrito, das indústrias existentes na mancha urbana paulista; o qual expressa à distribuição dos riscos e perigos construídos ao longo de décadas no território do município de São Paulo. Na segunda parte, aborda-se como o poder público trata o tema; suas dificuldades e acertos.

    Yavari, Arash; Ozakin, Arkadas; Sadik, Souhayl

    2016-07-01

    In this paper, we formulate a nonlinear elasticity theory in which the ambient space is evolving. For a continuum moving in an evolving ambient space, we model time dependency of the metric by a time-dependent embedding of the ambient space in a larger manifold with a fixed background metric. We derive both the tangential and the normal governing equations. We then reduce the standard energy balance written in the larger ambient space to that in the evolving ambient space. We consider quasi-static deformations of the ambient space and show that a quasi-static deformation of the ambient space results in stresses, in general. We linearize the nonlinear theory about a reference motion and show that variation of the spatial metric corresponds to an effective field of body forces.

    Full Text Available OBJETIVO: Revisar os artigos mais relevantes sobre a pediatria ambiental, seus efeitos potenciais para a saúde e, especialmente, seus avanços na prevenção. 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.

Questa si estende per 1668 ha lungo il crinale Appenninico a quote comprese fra 700 e 1200 m. Per l?indagine si sono utilizzate 220 trappole a caduta, per un totale di 29700 giorni/ trappola, visitate mensilmente e dislocate in 8 stazioni che rappresentano le principali tipologie ambientali presenti nella Riserva: Boschi (Ceduo e Alto fusto, aree aperte a diversa conduzione (Prato, Pascolo e Coltivo e Torrenti (i tre principali bacini idrici della Riserva. La frequenza di cattura è stata espressa come ?Densità di Attività? (DA che indica l?attività di ogni specie per ogni stazione, in relazione al numero di trappole attive e ai giorni di campionamento. Ai valori di DA abbiamo applicato opportuni indici sintetici ottenendo la caratterizzazione delle singole tipologie ambientali e della Riserva nel suo insieme. Gli indici usati sono quelli di Livello Trofico (ILT, Ricchezza Tassonomica di Shannon-Wiener (SH e Diversità Biotica di Gini-Simpson (GINI. L?applicazione di tali indici ai rilievi nelle 8 diverse stazioni nel periodo primavera-estate ?98 ha fatto registrare i valori più bassi di tutta la Riserva nella stazione Pascolo, denunciando un evidente degrado.

  4. Damage localization under ambient vibration using changes in flexibility

    Science.gov (United States)

    Gao, Yong; Spencer, B. F.

    2002-06-01

    In recent years, Structural Health Monitoring (SHM) has emerged as a new research area in civil engineering. Most existing health monitoring methodologies require direct measurement of input excitation for implementation. However, in many cases, there is no easy way to measure these inputs - or alternatively to externally excite the structure. Therefore, SHM methods based on ambient vibration have become important in civil engineering. In this paper, an approach is proposed based on the Damage Location Vector (DLV) method to handle the ambient vibration case. Here, this flexibility-matrix-based damage localization method is combined with a modal expansion technique to eliminate the need to measure the input excitation. As a by-product of this approach, in addition to determining the location of the damage, an estimate of the damage extent also can be determined. Finally, a numerical example analyzing a truss structure with limited sensors and noisy measurement is provided to verify the efficacy of the proposed approach.

    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 logics have been proposed to describe properties for mobile agents which may evolve over time as well as space. This paper takes a predicate-based approach to extending an ambient logic with recursion, yielding a predicate t-calculus in which fixpoint formulas are formed using predicate variables. An algorithm is developed for model checking finite-control mobile ambients against formulas of the logic, providing the first decidability result for model checking a spatial logic with recursion.

    Ambient Intelligence (AmI) is a new paradigm in information technology aimed at empowering people's capabilities by the means of digital environments that are sensitive, adaptive, and responsive to human needs, habits, gestures, and emotions. This futuristic vision of daily environment will enable innovative human-machine interactions characterized by pervasive, unobtrusive and anticipatory communications. Such innovative interaction paradigms make ambient intelligence technology a suitable candidate for developing various real life solutions, including in the health care domain. This survey will discuss the emergence of ambient intelligence (AmI) techniques in the health care domain, in order to provide the research community with the necessary background. We will examine the infrastructure and technology required for achieving the vision of ambient intelligence, such as smart environments and wearable medical devices. We will summarize of the state of the art artificial intelligence methodologies used for developing AmI system in the health care domain, including various learning techniques (for learning from user interaction), reasoning techniques (for reasoning about users' goals and intensions) and planning techniques (for planning activities and interactions). We will also discuss how AmI technology might support people affected by various physical or mental disabilities or chronic disease. Finally, we will point to some of the successful case studies in the area and we will look at the current and future challenges to draw upon the possible future research paths. PMID:24431472

    Ambient noise data measured in an experiment conducted in shallow water near a sea-route were analyzed. It was observed that, at low frequency, the horizontal correlation has an obvious difference from that predicted by the classical ambient noise model. The theoretical analyses show that this phenomenon is caused by wind noise together with the discrete shipping noise nearby. An ambient noise model was proposed to include the effects caused by both the noise sources. Data measured at different times verify that the proposed model can be used to forecast the ambient noise field in shal-low water near the sea-route.

O foco do trabalho é a capacidade política e institucional do município criada para tratar de tais questões. Os métodos usados foram pesquisa documental, bibliográfica e de campo, com entrevista a gestores do município. A pesquisa identificou que o município conta com propostas com grande potencial de contribuição para a melhoria da qualidade ambiental e habitacional na área de mananciais, principalmente por seu caráter de integração entre planejamentos. O estabelecimento de conselhos com participação de várias pastas representa um potencial elemento de integração nas ações desses órgãos, permitindo o compartilhamento de temas pertinentes ao longo do desenvolvimento das agendas de forma contínua. Quanto à recuperação urbana e ambiental dos loteamentos irregulares, é possível afirmar que os parâmetros urbanísticos e a definição do uso e ocupação do solo estão intimamente relacionados à qualidade ambiental e precisam ser construídos em conjunto por profissionais da área de urbanismo e da área ambiental, e discutidos com a comunidade local. O formato de gestão na área de mananciais, foco deste estudo de caso no município de Santo André, representa um significativo passo na construção da integração entre os sistemas de gerenciamento de recursos hídricos e de planejamento urbano/metropolitano.This article aims to survey and discuss environmental management actions and their interfaces with the housing issue in the area administered by the sub City Hall of Paranapiacaba and Parque Andreense, Santo André, SP.

    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.

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

    2011-06-01

    Full Text Available Configuration of the computing and communications systems found at home and in the workplace is a complex system design that currently requires the attention of the user. Recently, researchers have begun to explore computers that would autonomously configure their functionality based on observations of who or what is surrounding them. By determining their context, using input from sensor systems distributed throughout the environment, computing devices could personalize themselves to their current user, adapt their behaviouraccording to their location, or interact to their surroundings. This field of intelligence is called Ambient Intelligence (AmI. There has been increasing interest in building networks with AmI, which incorporates the user-centricity and context awareness, or in short AmI is a new information paradigm where people are empowered through a digital environment that is “aware” of their presence, context and is sensitive, adaptive, responsive to their needs and requests. Users’ environments are going to be disseminated of intelligentadaptive devices and sensors that will coordinate each other to help users in their activities with the help of AmI concepts and designs. This paper introduces the concept of AMI, explains the need for such an intelligence and also waves light over the different innovations done in this promising field of science and technology. This paper also addresses the topic of providing context aware services in smart environments. We review recent works in smart environments, and further defines and debates essential aspects concerning context-aware service supply. Future challenges for the research in context-aware smart environments are also discussed.

    Full Text Available Mener une politique de gestion efficace contre les phénomènes de prolifération des espèces exotiques envahissantes passe par des mesures de réglementation, mais aussi de prévention, nécessitant la mise en place de réseaux organisés de surveillance et de détection précoce de nouvelles espèces sur le territoire. Comment mieux organiser ces réseaux et coordonner l'action des différents acteurs, scientifiques, gestionnaires, associations et pouvoirs publics ? Quelques pistes nous sont suggérées dans cet article.It is quite difficult to eradicate an invasive alien species when it has already begun to spread. Even containment is very complicated, expensive andmay be harmful for natural ecosystems. For these reasons, it is necessary to improve prevention in order to foresee future invasions. The creation of a national list prioritized by negative impacts and specifying restrictivemeasures (black list would be a consistent progress for the enhancement of actual legislation and the nation could take a step forward on the way to prevention. In the same way, voluntary approaches and participative initiatives can be developed as it is already done for several years with different stakeholders. Finally, because of the unfeasibility tomaster the knowledge of incoming species, setting up surveillance networks is essential. These networks are useful for a better detection of newly established species, but they alsomust facilitate rapid responses to control incipient populations of undesirable invaders. With the purpose of driving these networks to optimization, early detection areas have to be targeted and specific toolsmust be developed. This new strategy also involves a better targeting and training of the stakeholders that willmake it become alive.

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

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

Esta última supone una oportunidad para larecuperación de los ecosistemas, una necesidad urgente dada la actual crisis ambiental. La comunidad de dispersores frugívoros es determinantepara recuperar la estructura y complejidad de la vegetación en campos abandonados, ya que éstos suelen estar desprovistos de propágulos.Recientes estudios han resaltado la especial relevancia de los mamíferos frugívoros en el proceso de dispersión de semillas en ambientesdegradados como los campos abandonados. Esto es debido a una serie de rasgos morfológicos y de comportamiento que caracterizan a losfrugívoros mamíferos y que les hace ser dispersores especialmente efectivos. Generalmente los mamíferos frugívoros tienen un mayor tamañocorporal, mayores áreas de campeo y distancias de dispersión, frecuente uso de hábitats abiertos, movilizando así más semillas hasta los camposabandonados que otros grupos de frugívoros (e.g. aves. Una vez que una semilla ha sido depositada tiene que superar las sucesivas etapas hastael establecimiento (depredación post-dispersiva, germinación, supervivencia y crecimiento. Los mamíferos frugívoros favorecen todo este procesoen mayor medida que otros dispersores. A nivel interespecífico pueden dispersar mayor diversidad de especies al estar generalmente menoslimitados por el tamaño de fruto, y a nivel intra-especifico no seleccionan semillas de pequeño tamaño. Además, suelen depositar las semillas enmicrohábitats que resultan especialmente adecuados para el reclutamiento.

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

    Full Text Available 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.

Using combinations of different types of sample introduction systems and ionization methods, several novel techniques have been developed over the last few years with many applications (e.g., food safety screening; detection of pharmaceuticals and drug abuse; monitoring of environmental pollutants; detection of explosives for antiterrorism and forensics; characterization of biological compounds for proteomics and metabolomics; molecular imaging analysis; and monitoring chemical and biochemical reactions). Electrospray ionization and atmospheric pressure chemical ionization are the two main ionization principles most commonly used in ambient ionization mass spectrometry. This tutorial paper provides a review of the publications related to ambient ionization techniques. We describe and compare the underlying principles of operation, ionization processes, detecting mass ranges, sensitivity, and representative applications of these techniques.

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

    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.

  9. Effect of dry and wet ambient environment on the pulsed laser ablation of titanium

    International Nuclear Information System (INIS)

    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/cm2. 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.

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

    2014-09-01

    We develop an approach for combining illuminance and spectral power distribution of the LED and ambient light and apply our technique for developing an LED camera flashlight balancing the illuminance contrast between object and background. Our method uses the closed loop, multiobjective optimization comprising: (1) characterizing the lighting task by illuminance, correlated color temperature (CCT), and statistical color quality indices that include a set of Statistical Color Quality Metrics and the Color Rendition Index (CRI) implemented with indexes of S (saturation) or D (dulling); (2) measuring the illuminance and the spectrum of the ambient light on the target lighting surface, which might depend on all the sources proving illumination and on the reflected light; (3) determining the desired illuminance of the LED source on the target lighting surface; (4) calculating the desired luminous flux of the LED source according to the desired illuminance; (5) constituting the SPD of the LED source; (6) calculating the relative spectra counts of the LED source and the ambient light on the target lighting surface (7) calculating the CCT and statistical color quality indexes of the combined light; (8) repeating the above steps until the resulting SPD is close enough to the expectation. Using the above method, an LED camera flashlight has been designed, which works together with usual fluorescent ambient light and generates working lighting environment with high fidelity and high CCT (6000K). The spectrum and luminous flux of the LED lamp is automatically tunable with a change of the ambient light.

Não se trata de um estudo epistemológico, mas sim de reflexões sobre a que se referem essas expressões e as implicações para a temática ambiental e, consequentemente para o Ensino de Ciências. A natureza foi compreendida como um complexo de entidades reais, as quais são passíveis de pensamento através da percepção. Essa mesma entidade ao ser representada por uma mente, passa a constituir o que denominamos de ambiente. Este, por sua vez, caracteriza-se não somente pela soma dos meios ambientes das espécies conhecidas, mas por ser uma abstração humana. Ao considerarmos a singularidade de cada espécie e organismo que nesse ambiente se insere, passamos a denominar de meio ambiente os elementos que podem ser percebidos e sobre as quais determinado ser pode atuar. Assim, buscamos elaborar um conceito de meio ambiente mais amplo, que não se restrinja à espécie humana.The concepts of environment, environment and nature in the context of environmental issue: defining meaningsABSTRACTWe present some clarifications that enable us to identify differences between the expressions nature, the environment and environment.

The nature was understood as a complex of real entities, which are capable to be thinking through perception. This same entity when is represented by a mind, become what we call the environment. This expression, in turn, is characterized not only by adding the environments species that are known, but to be a human abstraction. When we consider the uniqueness of each species and organism, which in this environment is inserted, we call environment, this is, the elements that can be seen and on which the organism can act

A Dakar, la question de la mobilité urbaine est exacerbée par les puissants mouvements pendulaires entre la ville centrale et la périphérie amplifiés par les stationnements anarchiques et par l’inorganisation des modes de transports urbains.Le type d’espace public choisi pour cet article est une gare routière située au cœur du Plateau de Dakar : Petersen.

    CERN Document Server

    Carey, William M

    2011-01-01

    This book develops the theory of ocean ambient noise mechanisms and measurements, and also describes general noise characteristics and computational methods.  It concisely summarizes the vast ambient noise literature using theory combined with key representative results.  The air-sea boundary interaction zone is described in terms of non-dimensional variables requisite for future experiments.  Noise field coherency, rare directional measurements, and unique basin scale computations and methods are presented.  The use of satellite measurements in these basin scale models is demonstrated.  Finally, this book provides a series of appendices giving in-depth mathematical treatments.  With its complete and careful discussions of both theory and experimental results, this book will be of the greatest interest to graduate students and active researchers working in fields related to ambient noise in the ocean.

  2. Ambient Noise Tomography of the British Isles

    Nicolson, H. J.; Curtis, A.; Baptie, B.

    2009-12-01

    In recent years, surface wave tomography using empirical Green’s functions computed via the ambient noise interferometry method has become an established approach to lithospheric imaging problems. To date, ambient noise tomography has been successfully applied to seismometer arrays in the United States, Australia, Iceland, China, South Africa, Europe and the Tibetan Plateau. The basis of the ambient seismic interferometry method is that, by cross-correlating noise data between two seismic stations and stacking over a long enough time period, one can approximate the Green’s Function that would have been recorded at one of the stations if the other had actually been a source. Consequently, one of the main advantages of ambient noise interferometry is that traditional seismic sources such as earthquakes or ballistics are not required; therefore it is ideal for application to seismically quiescent areas such as the British Isles. The British Isles are an archipelago located adjacent to the Eurasian continental shelf in a typically intra-plate setting, formed by a complex amalgamation of several terranes. These range from Laurentian north of the Highland Boundary fault to Avalonian south of the Iapetus Suture and evidence of the regions turbulent geological past can be inferred from its lithospheric structure. Previous studies of the structure of the British Isles considered relatively few seismic stations and/or were limited to using offshore shots, quarry blasts or teleseismic earthquakes as seismic energy sources. We have applied the ambient noise tomography method to noise data recorded on approximately 100 broadband and short period seismometers, including many new stations, in the British Isles and mainland Europe. This dense coverage of the British Isles allows us to image the crust and upper mantle velocity structure with a horizontal resolution in the region of 100km across the North Sea and 30km in the mainland United Kingdom. Here we present the first

  13. Valutazione farmacoeconomica dell’uso di tramadolo vs ketorolac nella gestione del dolore postoperatorio

    Directory of Open Access Journals (Sweden)

    Lorenzo G. Mantovani

    2003-03-01

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

    The laboratory of environmental radiation of ITA (São José dos Campos, 23°11'11″S, 45°52'43″W, 650 MAMSL) performs simultaneous monitoring of a natural radiation background and meteorological parameters. Neutron flux in the energy range of 0.02 eV - 10 MeV is registered with two sets of proportional ^{3}He tubes placed into cylindrical paraffin thermalizers: an {bf outdoor detector }of 250 cm² area and {bf indoor detector }of 70 cm² area located on the second floor of a concrete building. The counter efficiency for thermal neutrons is 80%. The characteristics of the observed flux variation are quite different from those inherent to the neutrons of the cosmic ray origin. {bf Four types of the outdoor flux variations }are observed: 1) {bf seasonal }with a maxima in wet seasons; 2) {bf diurnal }with maximum at about 6 h local time and an amplitude up to several dozens; 3) {bf abrupt transient} ( 1 min) increases with magnitudes up to two orders higher than the mean daily flux; 4) short (several days) {bf quasi-periodic enhancements }with amplitudes up to several times higher than the mean daily flux. A large variation of the outdoor flux and its phase synchronism with that of the radon decay products means with a high probability their common origin. An apparent source of the neutrons observed is nuclear reactions of decay α-particles with the ground matter. In this case the dynamics of the outdoor flux variations of the first two types is controlled by those of the meteorological parameters in the locality. The third type events correlate with lightning strokes in the vicinity (Earth's crust triggered by minor seismological activity. The indoor flux is quite stable with a possible weak maximum at16 h not exceeding 0.1.

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

    Full Text Available 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.

The characteristics of the observed flux variation are quite different from those inherent to the neutrons of the cosmic ray origin. {bf Four types of the outdoor flux variations }are observed: 1) {bf seasonal }with a maxima in wet seasons; 2) {bf diurnal }with maximum at about 6 h local time and an amplitude up to several dozens; 3) {bf abrupt transient} ( 1 min) increases with magnitudes up to two orders higher than the mean daily flux; 4) short (several days) {bf quasi-periodic enhancements }with amplitudes up to several times higher than the mean daily flux. A large variation of the outdoor flux and its phase synchronism with that of the radon decay products means with a high probability their common origin. An apparent source of the neutrons observed is nuclear reactions of decay α-particles with the ground matter. In this case the dynamics of the outdoor flux variations of the first two types is controlled by those of the meteorological parameters in the locality. The third type events correlate with lightning strokes in the vicinity (<200 m) of the detector. The more rare fourth type correlate neither with geomagnetic disturbances nor with meteorological phenomena and are probably a result of natural radon release from the Earth's crust triggered by minor seismological activity. The indoor flux is quite stable with a possible weak maximum at16 h not exceeding 0.1.

    Parra, J.; George, L. A.

    2009-12-01

    Concerns about the health effects of nitrogen dioxide (NO2) and its role in forming deleterious atmospheric species have made it desirable to have low-cost, sensitive ambient measurements of NO2. A continuous-wave laser-diode Laser Induced Fluorescence (LIF) system for NO2 that operates at ambient pressure has been developed, thereby eliminating the need for an expensive pumping system. The use of high quality optical filters has facilitated low-concentration detection of NO2 using atmospheric pressure LIF by providing substantial discrimination against scattered laser photons without the use of time-gated electronics, which add complexity and cost to the LIF instrumentation. This improvement allows operation at atmospheric pressure with a low-cost diaphragm sampling pump. The current prototype system has achieved sensitivity several orders of magnitude beyond previous efforts at ambient pressure (LOD of 2 ppb, 60 s averaging time). Ambient measurements of NO2 were made in Portland, OR using both the standard NO2 chemiluminescence method (CL-NO2) and the LIF instrument and showed good agreement (r2 = 0.92). Our instrument is currently being developed as a “back-end” detector for a more field portable NOy system. In addition, we are currently utilizing this instrument to study surface chemistry involving NO2 at atmospherically relevant concentrations and pressures.

  18. Revealing source signatures in ambient BTEX concentrations

    International Nuclear Information System (INIS)

    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

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

  1. Damage Localization of Offshore Platforms Under Ambient Excitation

    杨和振; 李华军; 王树青

    2003-01-01

    In this paper Nondestructive Damage Detection (NDD) for offshore platforms is investigated under operational conditions. As is known, there is no easy way to measure ambient excitation, so damage detection methods based on ambient excitation have become very vital for the Structural Health Monitoring (SHM) of offshore platforms. The modal parameters (natural frequencies, damping ratios and mode shapes) are identified from structural response data with the Natural Excitation Technique (NExT) in conjunction with the Eigensystem Realization Algorithm (ERA). A new method of damage detection is presented, which utilizes the invariance property of element modal strain energy. This method is to assign element modal strain energy to two parts, and defines two damage detection indicators. One is compression modal strain energy change ratio (CMSECR); the other is flexural modal strain energy change ratio (FMSECR). The present modal strain energy is obtained by incomplete modal shape and structural stiffness matrix. Structural health monitoring is thus accomplished via monitoring the elemental CMSECR and FMSECR. Several damage cases are simulated by an offshore platform numerical model, and presented to illustrate the utility of the proposed method. According to the damage localization results, the proposed method is shown to be effective and precise for complex structural damage detection.

    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). This includes some examples for the management of electricity demand for both the lighting and refrigeration cases in large (> 2500 m{sup 2}) supermarkets for the French environmental and energy management agency (Ademe).

  3. 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

  4. Developments in ambient noise analysis for the characterization of dynamic response of slopes to seismic shaking

    Science.gov (United States)

    Del Gaudio, Vincenzo; Wasowski, Janusz

    2016-04-01

    In the last few decades, we have witnessed a growing awareness of the role of site dynamic response to seismic shaking in slope failures during earthquakes. Considering the time and costs involved in acquiring accelerometer data on landslide prone slopes, the analysis of ambient noise offers a profitable investigative alternative. Standard procedures of ambient noise analysis, according to the technique known as HVNR or Nakamura's method, were originally devised to interpret data under simple site conditions similar to 1D layering (flat horizontal layering infinitely extended). In such cases, conditions of site amplification, characterized by a strong impedance contrast between a soft surface layer and a stiff bedrock, result in a single pronounced isotropic maximum of spectral ratios between horizontal and vertical component of ambient noise. However, previous studies have shown that the dynamic response of slopes affected by landslides is rather complex, being characterized by multiple resonance peaks with directional variability, thus, the use of standard techniques can encounter difficulties in providing reliable information. A new approach of data analysis has recently been proposed to exploit the potential of information content of Rayleigh waves present in ambient noise, with regard to the identification of frequency and orientation of directional resonance. By exploiting ground motion ellipticity this approach can also provide information on vertical distribution of S-wave velocity, which controls site amplification factors. The method, based on the identification of Rayleigh wave packets from instantaneous polarization properties of ambient noise, was first tested using synthetic signals in order to optimize the data processing system. Then the improved processing scheme is adopted to re-process and re-interpret the ambient noise data acquired on landslide prone slopes around Caramanico Terme (central Italy), at sites monitored also with accelerometer

    卢新培; 刘明海; 江中和; 潘垣

    2002-01-01

    The effects of the ambient pressure Pambient on the bubble characteristics of pulsed discharge in water are investigated. The simulation results show that, when Pambient increases from 1 atm to 100 atm, the bubble radius R decreases from 4cma to 7mm, and its pulsation period decreases frown 8ms to 0.2ms. The results also show that the peak pressure of the first shock wave is independent of Pambient, but the peak pressure of the second shock wave caused by the bubble re-expansion decreases when Pambient increases. On the other hand, the larger the ambient pressure, the larger the peak pressure of the plasma in the bubble, while the plasma temperature is independent of Pambient.

  8. Photometric Ambient Occlusion for Intrinsic Image Decomposition.

    Hauagge, Daniel; Wehrwein, Scott; Bala, Kavita; Snavely, Noah

    2016-04-01

    We present a method for computing ambient occlusion (AO) for a stack of images of a Lambertian scene from a fixed viewpoint. Ambient occlusion, a concept common in computer graphics, characterizes the local visibility at a point: it approximates how much light can reach that point from different directions without getting blocked by other geometry. While AO has received surprisingly little attention in vision, we show that it can be approximated using simple, per-pixel statistics over image stacks, based on a simplified image formation model. We use our derived AO measure to compute reflectance and illumination for objects without relying on additional smoothness priors, and demonstrate state-of-the art performance on the MIT Intrinsic Images benchmark. We also demonstrate our method on several synthetic and real scenes, including 3D printed objects with known ground truth geometry. PMID:26959670

  9. Ambient Intelligence Research Landscapes: Introduction and Overview

    Science.gov (United States)

    Streitz, Norbert

    This paper starts out by introducing the "Landscapes" category at the Joint International Conference on Ambient Intelligence (AmI-2010) and provides an overview over the two sessions. The main part of the paper presents a framework for the role of Ambient Intelligence in the development of the cities of the future. This includes the integration of real and virtual worlds resulting in Hybrid Cities and their transformation into Smart Cities. In the context, it is argued that the technological development has to be monitored by guidelines and goals for maintaining and improving the quality of life leading to what is called Humane Cities, addressing, e.g., social awareness and privacy, trust and identity. The paper closes with proposals for a future research agenda.

    A survey of the literature on the incidence of the age of onset of presbyopia in various parts of the world reveals a great deal of variation. At first sight this appears to correlate with geographical latitude, but statistical and epidemiological evidence rules this out in favour of ambient temperature. Indirect evidence suggests that the crystalline lens is located sufficiently near to the surface of the body for this to be a likely explanation.

  5. Topographic Effects on Ambient Dose Equivalent Rates from Radiocesium Fallout

    CERN Document Server

    Malins, Alex; Machida, Masahiko; Saito, Kimiaki

    2015-01-01

    Land topography can affect air radiation dose rates by locating radiation sources closer to, or further, from detector locations when compared to perfectly flat terrain. Hills and slopes can also shield against the propagation of gamma rays. To understand the possible magnitude of topographic effects on air dose rates, this study presents calculations for ambient dose equivalent rates at a range of heights above the ground for varying land topographies. The geometries considered were angled ground at the intersection of two planar surfaces, which is a model for slopes neighboring flat land, and a simple conical geometry, representing settings from hilltops to valley bottoms. In each case the radiation source was radioactive cesium fallout, and the slope angle was varied systematically to determine the effect of topography on the air dose rate. Under the assumption of homogeneous fallout across the land surface, and for these geometries and detector locations, the dose rates at high altitudes are more strongly...

    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.

  8. Object detectability at increased ambient lighting conditions

    International Nuclear Information System (INIS)

    Under typical dark conditions encountered in diagnostic reading rooms, a reader's pupils will contract and dilate as the visual focus intermittently shifts between the high luminance display and the darker background wall, resulting in increased visual fatigue and the degradation of diagnostic performance. A controlled increase of ambient lighting may, however, reduce the severity of these pupillary adjustments by minimizing the difference between the luminance level to which the eyes adapt while viewing an image (Ladp) and the luminance level of diffusely reflected light from the area surrounding the display (Ls). Although ambient lighting in reading rooms has conventionally been kept at a minimum to maintain the perceived contrast of film images, proper Digital Imaging and Communications in Medicine (DICOM) calibration of modern medical-grade liquid crystal displays can compensate for minor lighting increases with very little loss of image contrast. This paper describes two psychophysical studies developed to evaluate and refine optimum reading room ambient lighting conditions through the use of observational tasks intended to simulate real clinical practices. The first study utilized the biologic contrast response of the human visual system to determine a range of representative Ladp values for typical medical images. Readers identified low contrast horizontal objects in circular foregrounds of uniform luminance (5, 12, 20, and 30 cd/m2) embedded within digitized mammograms. The second study examined the effect of increased ambient lighting on the detection of subtle objects embedded in circular foregrounds of uniform luminance (5, 12, and 35 cd/m2) centered within a constant background of 12 cd/m2 luminance. The images were displayed under a dark room condition (1 lux) and an increased ambient lighting level (50 lux) such that the luminance level of the diffusely reflected light from the background wall was approximately equal to the image Ladp value of 12 cd

L'impostazione del lavoro svolto si basa sull'osservazione del processo di gestione aziendale: al fine di raggiungere i suoi obiettivi, l'Azienda trasforma delle risorse, ciascuna con il proprio ciclo di vita, attraverso fasi di gestione classificabili in valutazione, decisione, esecuzione e controllo. Tali fasi sono attuate attraverso il trattamento delle informazioni che rappresentano il legame tra esse nonche' la risorsa principale dell'intera organizzazione e il cardine del Sistema Informativo Gestionale.

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.

Cette vision est certes un peu extrême, mais il n’en reste pas moins que, dans la relations agriculture-territoire, le sol a occupé progressivement une position de plus en plus secondaire. Une des manifestations spécifiques à notre pays de cette indifférence croissante est la faiblesse des moyens dont il s’est doté pour connaître et gérer la diversité de sa couverture pédologique. Il ne dispose ni d’un inventaire exhaustif suffisamment précis pour répondre aux besoins de l’agriculture et de la décision publique, ni d’un outil de surveillance efficace de l’état de son patrimoine sol. Enfin, la protection des sols n’y est assurée que très partiellement par des dispositions juridiques ou réglementaires. L’évolution récente du contexte agricole, qu’elle concerne les mécanismes de soutien et de formation de revenu, les exigences de compétitivité et de qualité des produits, les liens au territoire et à l’environnement ou la recherche de la durabilité, conduit à une révision profonde de cette attitude. Cette nouvelle donne porte en gestation de nouvelles manières de produire et, plus généralement, de nouvelles méthodes de gestion de l’espace rural dans lesquelles le sol et son évolution devront être beaucoup plus fortement pris en compte. C’est la nécessité de ce changement et ses implications en matière de mobilisation des connaissances sur le sol qui constituent le propos de cet article.

  14. Event-driven approach to ambient-noise seismic interferometry

    Science.gov (United States)

    Draganov, Deyan; Campman, Xander; Thorbecke, Jan; Verdel, Arie; Wapenaar, Kees

    2010-05-01

    During the last decade, seismic interferometry, or SI, has gained rapidly in popularity among academia and the petroleum-exploration industry. One application of SI is the retrieval of the Earth's reflection response from cross-correlation of ambient seismic noise. In general, no information is available beforehand on the noise sources. For this reason, the ambient noise is assumed to originate from spatially uncorrelated, stationary noise sources that illuminate the recording array from all directions. To ensure this in the field, one wants to use recording times as long as possible. Correlating these long noise recordings would result in obtaining the best possible estimate of the complete Green's function including reflections and surface waves. The assumption of the spatially uncorrelated, stationary noise sources is not necessarily fulfilled, especially with measurements in the field taken during a limited time span. Results from different studies of ambient-noise SI for surface-wave tomography on global and regional scale have shown that when energy is used in the primary- and double-frequency-microseism bands, approximately between 0.07 Hz and 0.5 Hz, the majority of the recorded noise represents surface waves. After cross-correlation, such noise would result in the retrieval of only surface waves. For this reason one can choose to follow an alternative approach - to look in the ambient-noise data for parts of the noise that can be identified as body-wave arrivals (events). Such parts of the noise are then extracted and only they are used for SI. In this way, the correlated energy is manipulated to boost the contributions to the retrieval of body-wave reflections and, at the same time, minimize the contribution of those parts of the noise records that would retrieve surface waves. We apply the event-driven approach to about 11 hours of ambient seismic noise recorded by Shell in Libya. The noise, recorded by the vertical-component geophones, is stored in

    Full Text Available One of the greatest challenges to language rehabilitation is reconciling the fact that the same therapeutic intervention, provided to different individuals with similar types of stroke-induced aphasia, may result in divergent outcomes. In this paper, the authors reviewed existing literature to identify relevant ambient factors – those outside the control of the clinician – that may potentially influence functional language recovery in aphasia and response to treatment. The goal was to develop a clinical history-taking tool to assist clinicians in gathering information germane to each individual’s unique circumstances and environment, elements that may have previously been underestimated, to provide a complete inventory of potentially potent prognostic factors. First, two of the authors, speech-language pathologists experienced in aphasia rehabilitation, identified and categorized factors that seemed likely to influence aphasia outcomes. Then, a wide range of literature was reviewed in an effort to identify factors empirically found to be potent influences on aphasia recovery. Where studies relating these factors to aphasia were not found, relevant research from allied fields that examined recovery from brain injury is reported. Moreover, some factors thought to be potentially potent have yet to be examined. Finally, the ambient factors supported by evidence were categorized as facilitators or barriers to functional improvement, and the Ambient Influences on Outcome Checklist (AOC was developed, including only those factors shown to be potent in the recovery process. It is hoped that this checklist can be used to more broadly assess potential prognostic influences in aphasia restitution, as well as spawn further research.

    González-Manteiga, W.; Prada-Sánchez, J. M.; Cao, R.; García-Jurado, I.; Febrero-Bande, M.; Lucas-Domínguez, T.

    In this paper we present a dynamic system which has been implemented to predict, every 5 min, the ambient concentrations of SO 2 in the neighbourhood of a power station run by ENDESA, the National Electricity Company of Spain, in As Pontes. This prediction task is very important in order to prevent a high ground-level of concentration of SO 2. For forecasting we use a mixed model which has a parametric component and a nonparametric one. We also construct confidence intervals for future observations using bootstrap and classical techniques.

    Being the alpechin one of the most contaminant residues by the mediterranean agrarian industry, as of today there is no integral depuration procedure. In this paper we show the innovative approach being used to eliminate the alpechin along with the oil miller residual biomass. What it more, the only agroindustrial complex which has introduced such approach is using an EMAS so that actual achievements could be realistically measured. (Author) 12 refs.

This paper focuses on the application of some management tools that best fit to the minerals used in the ceramic and glass industry. (Author) 12 refs.

  17. 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

    Full Text Available 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.

  19. Disseminating Ambient Assisted Living in Rural Areas

    Gerhard Leitner

    2014-07-01

    Full Text Available 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.

    Full Text Available El medio ambiente constituye, actualmente, uno de los campos de estudio interdisciplinarios que ha venido recibiendo una atención priorizada por parte de la comunidad científica mundial. La Psicología constituye una de las disciplinas que se interesa por el medio ambiente, tanto por la dinámica de la interacción individuomedio, como por la educación ambiental, siendo necesario, entonces, brindar información para hacer conciencia sobre nuestros comportamientos y su decisiva influencia en el contexto físico y social. Por otro lado, la calidad de vida es un concepto multidimensional y multidisciplinario que debe ser valorado desde la presencia de las condiciones materiales y espirituales que permitan el desarrollo psicobiológico y social-histórico del ser humano y la satisfacción personal con las condiciones de vida que cada persona ha logrado alcanzar. El concepto de calidad de vida se considera claramente relacionado con el concepto de salud humana y con la necesidad de promover una educación ambiental con proyección social y comunitaria.
