    Presently, all the organizations involved with nuclear activities must be one step ahead of what happens in the specific activity areas in order to avoid surprises, to guarantee their activity continuity and the objective extents, and taking into account the external environment influence exercised by the organization on their activities. So, it is necessary a continuous follow up of their transformations. This paper aims to structure a model of the environmental monitoring system oriented to the strategic planning of the Brazilian Nuclear Energy Commission, as function of that new informational needs viewing the fulfilment of that observed gap.

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

    Full Text Available A Psicologia precisa se engajar na análise e no encaminhamento de soluções para os problemas ambientais, pois estes são, de fato, problemas humano-ambientais. Para contribuir com esse propósito, um breve histórico da Psicologia Ambiental é apresentado, com destaque para as implicações teóricas e práticas de suas origens, internas e externas à Psicologia, tendo como pano de fundo a crise ambiental global. Descrevem-se alguns desdobramentos dessas fontes no contexto brasileiro, com o intuito de estimular uma crescente integração de esforços na área de estudo das inter-relações pessoa-ambiente. Aspectos teóricos e metodológicos são analisados, principalmente em vista da recente tendência internacional verificada na Psicologia Ambiental de enfatizar a determinação humana e social da chamada crise ambiental.Psychology should engage in the analysis of environmental problems, which are, in fact, human-environmental problems, aiming at their solution. To help accomplishing this goal, a brief historical account of Environmental Psychology is presented, emphasizing the theoretical and practical implications of its origins, internal and external to Psychology, with the environmental global crisis as background. Some developments of those sources within the Brazilian context are introduced to favor the integration of studies in the area of person-environment relationships. Some theoretical and methodological aspects are analyzed, especially in terms of the recent international tendency in Environmental Psychology to consider the human and social determination of the so called environmental crisis.

  6. Environmental scanning as information seeking and organizational learning

    Directory of Open Access Journals (Sweden)

    2001-01-01

    Full Text Available Environmental scanning is the acquisition and use of information about events, trends, and relationships in an organization's external environment, the knowledge of which would assist management in planning the organization's future course of action. Depending on the organization's beliefs about environmental analyzability and the extent that it intrudes into the environment to understand it, four modes of scanning may be differentiated: undirected viewing, conditioned viewing, enacting, and searching. We analyze each mode of scanning by examining its characteristic information needs, information seeking, and information use behaviours. In addition, we analyze organizational learning processes by considering the sensemaking, knowledge creating and decision making processes at work in each mode.

    1993-01-01

    It is demonstrated that the environmental embrittlement of ordered intermetallics, which is caused by hydrogen released from moisture in air or hydrogen gas in environment at ambient temperatures, takes place in various kinds of crystal structures, alloys and microstructures. First, the phenomenology of the environmental embrittlement, i.e. atmosphere, temperature and strain rate dependencies, as well as alloying, doping and microstructural effects, is presented in terms of mechanical properties, fractography and microstructural features. Next, possible mechanisms of embrittlement involving the kinetics (i.e. decomposition, migration and condensation of hydrogen) and the bond breaking are discussed. Finally, some evidence indicating suppression of the embrittlement through selection of deformation condition, alloying and microstructural modification is presented. 52 refs., 11 figs., 2 tabs

    Scanning electron microscopy (SEM) of nanoscale objects in dry and fully hydrated conditions at different temperatures is of critical importance in revealing details of their interactions with an ambient environment. Currently available WETSEM capsules are equipped with thin electron-transparent membranes and allow imaging of samples at atmospheric pressure, but do not provide temperature control over the sample. Here, we developed and tested a thermoelectric cooling/heating setup for WETSEM capsules to allow ambient pressure in situ SEM studies with a temperature range between -15 and 100°C in gaseous, liquid, and frozen conditions. The design of the setup also allows for correlation of the SEM with optical microscopy and spectroscopy. As a demonstration of the possibilities of the developed approach, we performed real-time in situ microscopy studies of water condensation on a surface of Morpho sulkowskyi butterfly wing scales. We observed that initial water nucleation takes place on top of the scale ridges. These results confirmed earlier discovery of a preexisting polarity gradient of the ridges of Morpho butterflies. Our developed thermoelectric cooling/heating setup for environmental capsules meets the diverse needs for in situ nanocharacterization in material science, catalysis, microelectronics, chemistry, and biology.

    2014-01-01

    Full Text Available In recent years, wireless sensor networks (WSNs have grown dramatically and made a great progress in many applications. But having limited life, batteries, as the power sources of wireless sensor nodes, have restricted the development and application of WSNs which often requires a very long lifespan for better performance. In order to make the WSNs prevalent in our lives, an alternative energy source is required. Environmental energy is an attractive power source, and it provides an approach to make the sensor nodes self-powered with the possibility of an almost infinite lifetime. The goal of this survey is to present a comprehensive review of the recent literature on the various possible energy harvesting technologies from ambient environment for WSNs.

    2015-04-01

    Identifying inequalities in air pollution levels across population groups can help address environmental justice concerns. We were interested in assessing these inequalities across major urban areas in Australia. We used a land-use regression model to predict ambient nitrogen dioxide (NO2) levels and sought the best socio-economic and population predictor variables. We used a generalised least squares model that accounted for spatial correlation in NO2 levels to examine the associations between the variables. We found that the best model included the index of economic resources (IER) score as a non-linear variable and the percentage of non-Indigenous persons as a linear variable. NO2 levels decreased with increasing IER scores (higher scores indicate less disadvantage) in almost all major urban areas, and NO2 also decreased slightly as the percentage of non-Indigenous persons increased. However, the magnitude of differences in NO2 levels was small and may not translate into substantive differences in health. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A transmission environmental scanning electron microscope with use of a scintillation gaseous detection device has been implemented. This corresponds to a transmission scanning electron microscope but with addition of a gaseous environment acting both as environmental and detection medium. A commercial type of low vacuum machine has been employed together with appropriate modifications to the detection configuration. This involves controlled screening of various emitted signals in conjunction with a scintillation gaseous detection device already provided with the machine for regular surface imaging. Dark field and bright field imaging has been obtained along with other detection conditions. With a progressive series of modifications and tests, the theory and practice of a novel type of microscopy is briefly shown now ushering further significant improvements and developments in electron microscopy as a whole.

    2010-01-01

    The exploration of remote planetary surfaces calls for the advancement of low power, highly-miniaturized instrumentation. Instruments of this nature that are capable of multiple types of analyses will prove to be particularly useful as we prepare for human return to the moon, and as we continue to explore increasingly remote locations in our Solar System. To this end, our group has been developing a miniaturized Environmental-Scanning Electron Microscope (mESEM) capable of remote investigations of mineralogical samples through in-situ topographical and chemical analysis on a fine scale. The functioning of an SEM is well known: an electron beam is focused to nanometer-scale onto a given sample where resulting emissions such as backscattered and secondary electrons, X-rays, and visible light are registered. Raster scanning the primary electron beam across the sample then gives a fine-scale image of the surface topography (texture), crystalline structure and orientation, with accompanying elemental composition. The flexibility in the types of measurements the mESEM is capable of, makes it ideally suited for a variety of applications. The mESEM is appropriate for use on multiple planetary surfaces, and for a variety of mission goals (from science to non-destructive analysis to ISRU). We will identify potential applications and range of potential uses related to planetary exploration. Over the past few of years we have initiated fabrication and testing of a proof-of-concept assembly, consisting of a cold-field-emission electron gun and custom high-voltage power supply, electrostatic electron-beam focusing column, and scanning-imaging electronics plus backscatter detector. Current project status will be discussed. This effort is funded through the NASA Research Opportunities in Space and Earth Sciences - Planetary Instrument Definition and Development Program.

    Objective The objective of this environmental scan was to identify Western Canadian interprofessional education (IPE) resources that currently exist for internationally educated health professionals (IEHPs). Methodology A web-based search was conducted to identify learning resources meeting defined inclusion criteria with a particular focus on the resources available in the Western Canadian provinces. Information was extracted using a standardized template, and we contacted IEHP programs for additional information if necessary. Members of the research team reviewed preliminary findings, identified missing information from their respective provinces, and contacted organizations to fill in any gaps. Results The scan identified 26 learning resources for IEHPs in Western Canadian provinces and 15 in other provinces focused on support for IEHPs to meet their profession-specific licensing requirements and to acquire knowledge and competencies relevant to working in the Canadian health care system. Most learning resources, such as those found in bridging programs for IEHPs, included an orientation to the Canadian health care system, components of cultural competence, and at least one aspect of interprofessional competence (eg, communication skills). None of the 41 learning resources provided comprehensive training for IEHPs to cover the six interprofessional competency domains defined in the Canadian Interprofessional Health Collaborative (CIHC) National Interprofessional Competency Framework. Conclusion The IEHPs learning resources in Western Canada do not cover all of the interprofessional competencies. This review points to the value of developing a comprehensive IPE curriculum, based on the six domains identified in the CIHC National Interprofessional Competency Framework. PMID:28424551

    In response to a growing and worldwide recognition of elder abuse, the WorldView Environmental Scan on Elder Abuse was undertaken. It represented an attempt to collect both information on the nature of the problem of elder abuse and responses to it from a global perspective. The first of its kind, the Scan gathered information about elder abuse as well as on related legislation and policy, services and programs, educational resources and needs, training, and past and ongoing research. A total of 53 countries responded to the survey questionnaire, with 362 respondents representing the six world regions designated by the World Health Organization. Findings revealed that factors contributing to elder abuse include changing social and economic structures, isolation of victims, inadequate knowledge of laws and services, intergenerational conflict, and poverty. Barriers to seeking resources to intervene and protect older adults include the culture of the country, language issues, literacy, stigma, lack of mobility, lack of funding, and insufficient familiarity with and access to the internet. The data serve as a catalyst to take action, both globally and nationally, while emphasizing the changes necessary to protect the rights and dignity of older adults.

    Thermoluminescence dosimetry is the principal means of measuring ambient γ radiation at the Lawrence Livermore Laboratory. These dosimeters are used at 12 perimeter locations and 41 locations in the off-site vicinity of the Laboratory, and are exchanged quarterly. Control dosimeters are stored in a 75-mm-thick lead shield located out-of-doors to duplicate temperature cycling of field dosimeters. Effect of dosimeter response to radiation in the shield is determined each quarter. Calibration irradiations are made midway through the exposure cycle to compensate for signal fading. Terrestrial exposure rates calculated from the activities of naturally occurring uranium, thorium, and potassium in Livermore Valley soils vary from 3 to 7 μR/hr. Local inferred exposure rates from cosmic radiation are approximately 4 μR/hr. TLD measurements are in good agreement with these data. Off-site and site perimeter data are compared, and differences related to Laboratory operations are discussed

    Human papillomavirus (HPV) vaccination rates are significantly lower than recommended targets. Public awareness campaigns can raise awareness of the severity and prevalence of HPV infection and the cancer prevention benefits of the vaccine. We conducted an environmental scan of HPV vaccine public awareness campaigns during the summer of 2014. We used online search strategies and expert input to identify candidate campaigns. Multiple study investigators reviewed all data abstraction and analysis. After applying our inclusion criteria, we identified 14 campaigns with parents or teenagers as the target audience. We characterized campaign messages according to constructs of the Health Belief Model. Most messages focused on the cancer prevention benefits of HPV vaccine; few addressed psychological or practical barriers to getting or completing the vaccine. Four of 14 campaigns had pre- or postcampaign data readily available, only 2 used vaccine outcomes in their evaluations. We concluded there was a high prevalence of HPV vaccine public awareness campaigns but little available evidence on their impact on intermediate or vaccine outcomes. © 2015 Society for Public Health Education.

    2012-01-01

    Quality indicators (QIs) are increasingly being used to measure and improve the quality of cardiac care. We conducted an international environmental scan to identify and critically appraise published QI development initiatives addressing cardiovascular disease (CVD). A review of the peer-reviewed and grey English-language literature was conducted to identify published CVD QI development initiatives. The quality of identified studies was assessed using a modified version of the Appraisal of Guidelines for Research and Evaluation (AGREE) II QI tool-an instrument originally developed for the assessment of the quality of clinical practice guidelines. An initial literature search identified 2314 potentially relevant abstracts of peer-reviewed articles. After a review of the abstracts, 120 full text articles were retrieved and reviewed. Of these, 20 articles and 1 peer-reviewed monograph were selected for critical appraisal (n = 21). Most of the initiatives were conducted in North America (76%) and were published after 2005 (62%). The majority (5 of 6) of the AGREE II QI domain scores were skewed toward higher values, including the median score for the 'overall quality' rating (83.3%). Of the CVD categories addressed within the 21 initiatives, heart failure was the most common (n = 10 QI indicator sets), followed by acute coronary syndromes (n = 8). Considerable variation was observed in the methods utilized and the degree of scientific rigour applied in the published international CVD QI development initiatives. Adoption of standardized methods could help improve the quality of QI development initiatives. Copyright © 2012 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

    Neutron production is a concern in proton therapy, particularly in scattering proton beam delivery systems. Despite this fact, little is known about the effects of secondary neutron exposure around wobbling scattered proton treatment nozzles. The objective of this study was to estimate the neutron dose level resulting from the use of a wobbling scattered proton treatment unit. We applied the Monte Carlo method for predict the ambient neutron dose equivalent, H*(10), per absorbed dose at the treatment isocenter, D, in the proton therapy center of Chang Gung Memorial Hospital, Linkou, Taiwan. For a 190-MeV proton beam, H* (10) / D values typically decreased with the distance from the isocenter, being 1.106 mSv/Gy at the isocenter versus 0.112 mSv/Gy at a distance of 150 cm from the isocenter. The H* (10) / D values generally decreased as the neutron receptors moved away from the isocenter, and increased when the angle from the initial beam axis increased. The ambient neutron dose equivalents were observed to be slightly lower in the direction of multileaf collimator movement. For radiation protection, the central axis of a proton-treated patient is suggested to be at the 0° angle of the beam. If the beam direction at the 90° angle is necessary, the patient axis is suggested to be along with the direction of MLC movement. Our study provides the neutron dose level and neutron energy fluence for the first wobbling proton system at the proton therapy center of Chang Gung Memorial Hospital.

  13. Environmentally Persistent Free Radical (EPFRs) - Ambient Air Particulates, Soils and Fate of Some Pollutants

    Lomnicki, S. M.

    2017-12-01

    Environmentally Persistent Free Radicals (EPFRs) are relatively recently discovered species that are present on ambient air particulates. Their origin is typically associated with the combustion borne PM, where in the cool zone of the combustion process aromatic precursors react with the metal centers of particulates forming surface-organic complex with radical characteristics. EPFRs have been found to be sufficiently resistant to be emitted from the combustion sources and persist in the ambient air on particulates. Their inhalation has been associated with severe health effects, and potentially are one of the major agents contributing the epidemiological risks of PM exposure. Interestingly, EPFRs can be formed not only at the elevated temperatures but also in ambient conditions, where the contact of precursor molecules with transition metal (but not only) domains can result in adsorbate complexes. In fact, EPFRs have been detected in the contaminated soils, or during the oil spill incidents. It is very likely, that the interaction of some molecules released to the air can result in the formation of EPFRs on the ambient air particulates in atmospheric conditions. These species can be a natural degradation by-products that lead to the formation of oxygenated organics in ambient atmosphere.

    Full Text Available O presente artigo propõe uma discussão em torno das possibilidades de uma educação ambiental queer. Tornar queer a educação ambiental significa mais que simplesmente adicionar conteúdo gay/lesbiano/bissexual/transgênero à educação ambiental, mas visa, em seu projeto, problematizar a heteronormatividade, a essencialização das identidades e a heterossexualização de nossas teorias e práticas. Apresentamos neste trabalho uma breve introdução à pedagogia queer e apontamos como a educação ambiental pode contribuir de maneira singular para a interrupção da heteronormatividade e para a problematização da identidade e da experiência. Também exemplificamos esforços por um ambientalismo queer em novos movimentos sociais e produções culturais.We wish to initiate discussion on the possibilities for queering environmental education. As a verb, "to queer" means more than simply adding gay/lesbian/bisexual/transgendered content to environmental education. Rather, queering has, at its heart, the project of problematizing heteronormativity, essentialized identities and the heterosexualization of our theories and practices. In this paper, we provide a brief introduction to queer pedagogy, point to the unique ways in which environmental education can contribute to the disruption of heteronormativity and the problematization of identity and of experience, and describe efforts to queer environmentalism in new social movements and cultural productions.

    Stereotypies are commonly observed in zoo animals, and it is necessary to better understand whether ambient environmental factors contribute to stereotypy and how to affect animal welfare in zoo settings. This study investigated the relationships between stereotypic behaviors and environmental factors including ambient temperatures, humidity, light intensity, sound intensity and number of visitors. Seven giant pandas were observed in three indoor enclosures and three outdoor enclosures. Environmental factors were measured for both indoor and outdoor enclosures and the effect they had on stereotypical behaviors was investigated. Our research found that light intensity significantly correlated with all stereotypies behaviors. Higher environmental temperature reduced the duration of pacing but increased the frequency of pacing, the duration and frequency of door-directed, meanwhile the duration of head-toss. However, we found no noticeable effect of humidity on stereotypic behaviors except for the frequency of head-toss. We also found that sound intensity was not correlated with stereotypies. Finally, the growth of visitors was negatively associated with the duration of door-directed. These results demonstrated that various environmental factors can have significant effects on stereotypic behaviors causing the expression of various stereotypies. Thus, stereotypies in zoo animals may not simply represent suboptimal welfare, but rather might be adopted as a means of coping with an aversive environment.

    Full Text Available Introduction. Environmental scanning, as a component of absorptive capacity, has been shown to be associated with increased use of innovative treatment techniques at substance abuse treatment programmes. As the transfer of innovative, evidence-based treatment techniques from research to practice is gaining attention, we aimed to identify variables associated with higher levels of environmental scanning among substance abuse treatment clinicians. Method. A cross-sectional survey was administered to 162 clinicians at 15 substance abuse treatment clinics in Michigan. Measures: Environmental scanning was measured by frequency of use of the Internet, journals, seminars or conferences, and people at other treatment clinics for new substance abuse treatment information. Clinicians were asked for their perceptions of their clinic’s openness to new treatment techniques and support for acquiring new information, access to and satisfaction with information sources at work, as well as if they feel it is their job to keep up to date with current treatment research. Additional measures included whether they intended to quit their jobs and whether they were emotionally drained from work. Findings: We found positive associations between environmental scanning and perceived clinic support for acquiring new information, perceived clinic openness to new treatment techniques, access to e-mail and Internet at work, and satisfaction with resources. Turnover intention and being emotionally drained were negatively associated with environmental scanning. Conclusion. : Individual and organizational level variables were found to be associated with higher levels of environmental scanning activity. Although the causal directions of these associations are not known, the findings suggest ways to increase environmental scanning among clinicians.

    The bioclimatic design profits of the natural resources for the improvement of the construction quality as well as the user's life. The combination of these two concepts within the architectonic design generates an interesting duality to consider within the understanding of the user's physical and psychological environment and the obtaining of a correlation of reality and dreams. Environmental psychology is focused on the researching of the psychological effects of the architectonic environment on the human experience and behavior. Human behavior works under parameters established during its development. Through the habits and styles of life practiced in childhood those parameters establish themselves to later on obtain satisfiers in the search of the life quality of human beings. [Spanish] El diseno bioclimatico aprovecha los recursos naturales para el mejoramiento de la calidad de la construccion y vida del usuario.

La psicologia ambiental se ha enfocado a investigar sobre la relacion de los efectos psicologicos del ambiente construido o arquitectonico sobre la conducta y la experiencia humana. La conducta humana trabaja bajo parametros establecidos durante el desarrollo del mismo, a traves de los habitos y estilos de vida desde su infancia van marcando esos parametros que despues sirven para lograr satisfactores en la busqueda de la calidad de vida de los seres humanos.

    A novel method for measuring an adhesion force of single yeast cell is proposed based on a nanorobotic manipulation system inside an environmental scanning electron microscope (ESEM). The effect of ambient humidity on a single yeast cell adhesion force was studied. Ambient humidity was controlled by adjusting the chamber pressure and temperature inside the ESEM. It has been demonstrated that a thicker water film was formed at a higher humidity condition. The adhesion force between an atomic force microscopy (AFM) cantilever and a tungsten probe which later on known as a substrate was evaluated at various humidity conditions. A micro-puller was fabricated from an AFM cantilever by use of focused ion beam (FIB) etching. The adhesion force of a single yeast cell (W303) to the substrate was measured using the micro-puller at the three humidity conditions: 100%, 70%, and 40%. The results showed that the adhesion force between the single yeast cell and the substrate is much smaller at higher humidity condition. The yeast cells were still alive after being observed and manipulated inside ESEM based on the result obtained from the re-culturing of the single yeast cell. The results from this work would help us to understand the ESEM system better and its potential benefit to the single cell analysis research. -- Research highlights: {yields} A nanorobotic manipulation system was developed inside an ESEM. {yields} A micro-puller was designed for single yeast cell adhesion force measurement. {yields} Yeast cells were still alive after being observed and manipulated inside ESEM. {yields} Yeast cell adhesion force to substrate is smaller at high humidity condition than at low humidity condition.

    Full Text Available Captivity is an extreme non-natural environment for primates. The success of a breeding colony depends of management and veterinarian procedures which must rely on the knowledge of primates' behavioral needs. Environmental enrichment consists of a series of procedures that improve the quality of life of captive animals by meeting their ethological needs. Enrichment can reduce stress, while increasing animal well being in captivity. Suitable ethical conditions, incidences of behavioral disorders, minimal clinical interventions, low mortality, higher reproduction rates and cost/benefit relationship, reflect directly on the quality of captive breeding colonies. Anthropoids like Neotropical primates possess complex neural structures and relate, in a sophisticated manner, to the environment. This review reports important experiences on enrichment procedures for Neotropical primates and the physiological events which could explain improvement of animal well-being.Cativeiro é um ambiente de extremos não naturais para primatas. O sucesso de uma criação de primatas depende do manejo e de procedimentos veterinários que devem considerar as necessidades etológicas dos animais cativos.

    This article is about two important scopes of the Bioclimatical Design (BD), the Social scope and the environmental scope. As an introduction, it is justified the importance of this topic through the association of the BD in the context of sustainability with our country's economic model. The analysis is done under the perspective of effects of the BD on social and environmental scopes. In social scope is used the Cost and Benefit Analysis according to social evaluation. In environmental scope, effects in water, air and ground are studied, but the measurement is done according to the emissions reduction of CO{sub 2} on atmosphere because of the earn on energy consumption. The results of the measurement of this effects are related with economical costs and benefits, which may show a general view about economical, social and environmental scopes. As conclusions, interest results are show and this is proposed to incorporate them in the economical politics.

It also discusses - from the standpoint of literature (Buttel, Dunlap, Hanning, among others - its theoretical-methodological and institutional aspects as well in order to understand the obstacles encountered to legitimate and consolidate a set of problems which, until recently, were not dealt with by social sciences. Secondly, it analyses the Brazilian case. Environmental sociology in Brazil is strongly influenced by American empirical sociology, the precursor of the institutionalization process for the themes. On the other hand, further analysis of this case is relevant to understand the relationship between the scientific sphere, and the creation of environmental policies and social movements.Primeiramente o artigo busca a reconstituição e análise histórica inerente ao escopo da sociologia ambiental internacional no contexto da sociologia contemporânea. Ele também discute - a partir da literatura (Buttel, Dunlap, Hanning, entre outros - seus aspectos teórico-metodológicos e institucionais de modo a compreender os obstáculos encontrados para se legitimar e consolidar um conjunto de problemas os quais, até recentemente, não eram trabalhados pelas Ciências Sociais. No segundo momento o artigo analisa o caso brasileiro. A sociologia ambiental no Brasil é fortemente influenciada pela sociologia empírica americana, a precursora no processo de institucionalização desses temas. Por outro lado, uma análise posterior sobre esse caso é relevante para se compreender a relação entre a esfera científica, a implementação de políticas ambientais e os movimentos sociais.

    Full Text Available Resumo: O princípio da responsabilidade impõe um imperativo moral, no sentido de que se deve agir de modo que os direitos estabelecidos sejam compatíveis com a permanência de uma autêntica vida humana na Terra. É com a intenção de atar firmemente a efetiva responsabilização pelo dano ambiental ao imperativo moral em seu viés preventivo e repressivo que este trabalho se põe em marcha. Os modos de vida humanos individuais e coletivos das sociedades ocidentais evoluem no sentido de uma progressiva deterioração do meio ambiente. É a relação da subjetividade com sua exterioridade que se encontra comprometida. Se não houver uma rearticulação dos três registros fundamentais da ecologia – subjetivo, social e ambiental –, podemos, infelizmente, pressagiar a escalada de todos os perigos que envolvem a sociedade atual. Em lugar da relação harmônica e sustentável com o meio ambiente, as sociedades de consumo introduziram a ideia da subjetividade que constrói o mundo que a circunda. A relação do sujeito com o mundo no qual se encontra deve ser sua principal preocupação. Para isso, torna-se imprescindível um envolvimento com a efetiva proteção do meio ambiente, caso se queira manter a vida na Terra para as presentes e futuras gerações. A implementação de uma hermenêutica jurídica eminentemente ambiental é o caminho jurídico para a efetiva proteção do chamado bem ambiental, considerando-se as especificidades do bem em comento. Na esteira dessa hermenêutica, o dano moral ambiental objetivo encontra respaldo, e o seu agente pode ser responsabilizado. Palavras-chave: Hermenêutica ambiental. Risco ambiental.

    Environmental seismology consists in studying the mechanical vibrations that originate from, or that have been affected by external causes, that is to say causes outside the solid Earth. This includes for instance the coupling between the solid Earth and the cryosphere, or the hydrosphere, the anthroposphere and the specific sources of vibration developing there. Environmental seismology also addresses the modifications of the wave propagation due to environmental forcing such as temperature and hydrology. Recent developments in data processing, together with increasing computational power and sensor concentration have led to original observations that allow for the development of this new field of seismology. In this article, we will particularly review how we can track and interpret tiny changes in the subsurface of the Earth related to external changes from modifications of the seismic wave propagation, with application to geomechanics, hydrology, and natural hazard. We will particularly demonstrate that, using ambient noise, we can track 1) thermal variations in the subsoil, in buildings or in rock columns; 2) the temporal and spatial evolution of a water table; 3) the evolution of the rigidity of the soil constituting a landslide, and especially the drop of rigidity preceding a failure event.

    Márcia Soares Spiller

    2018-03-01

    Full Text Available The phylum Arthropoda is one of the most diverse groups under the terrestrial surface comprising different classes of insects that occupy different environments. Some groups have a close relationship with the habitat they occupy, responding significantly to changes in the environment, thus indicating the level of change in the environment by their presence or absence. The present study aimed to demonstrate the importance of edaphic fauna as a bioindicator of environmental quality. This is a bibliographic review based on specialized consultation of scientific articles in the databases Google Scholar, SciELO-Scientific Electronic Library and ResearchGate. The studies found that environmental quality can be measured from the diversity and abundance of arthropods that live and perform their functions in the soil. Macrofauna influences important soil chemical and physical processes such as nutrient cycling, structuring and homogenization, and increased productivity, among others. The mesofauna, besides acting on soil properties, acts on the regulation of microbial populations, is sensitive to changes and responds promptly. The groups Acari, Collembola, Coleoptera, Hymenoptera and Araneae are indicated in several studies as potential bioindicators because they are commonly sampled in different environments. The factors identified as conditioning factors of the presence of these groups are environmental heterogeneity, type of vegetation cover and availability of litter, applied management system, seasonality, soil characteristics, and anthropic activities, among others. In short, because they respond quickly, the changes are considered to be efficient biological indicators; therefore, knowing the diversity of species and their degree of interaction with the environment allows us to analyze the effects of anthropic modifications in ecosystems. = O filo Arthropoda é um dos grupos mais diversos da superfície terrestre, compreendendo diferentes classes

    Full Text Available A Conferência Rio+20 mobiliza a comunidade global em 2012 para participar de um desafiador debate sobre a realidade ambiental global e modus operandi existente quanto à temática ampla e genérica do desenvolvimento e do ambiente. Um dos temas estruturantes desta reunião é a transição para uma economia verde no contexto do desenvolvimento sustentável e da erradicação da pobreza. O tema da Governança Ambiental Global um dos carros chefe do debate na Rio+20, no intuito de promover e acelerar a transição rumo a sociedades sustentáveis, configura a construção muitas vezes, de forma controversa, das condições para a definição de novos espaços institucionais e processos decisórios compartilhados. Este artigo propõe aos leitores uma reflexão para discutir que tipo de sustentabilidade está por trás da economia verde, a sua aplicabilidade e o que deva ser priorizada na discussão de governança ambiental. Isto se explica na medida em que existe a necessidade de mudar os mecanismos de utilização dos recursos, profundamente injustos, e que impedem avanços nos processos decisórios, pois as decisões de poucos tem configurado uma lógica perversa de expropriação de recursos naturais e não resolução da exclusão social.The Rio+20 Conference will mobilize the global community in 2012 to participate in a challenging debate on the global environmental reality and the existing modus operandi with respect to the broad and generic topics of development and the environment.

The issue of Global Environmental Governance will top the agenda of the Rio +20 discussions, with a view to promoting and accelerating the transition to sustainable societies. It presents, often in a controversial way, the creation of conditions to define new institutional spaces and shared decision-making processes

A atenção é dirigida especialmente às relações entre padrões de distribuição populacional no espaço e a mudança ambiental. Como taxas de mortalidade e fecundidade já passaram por transições enormes, migração é o fator central na mudança populacional e seus impactos sobre o ambiente. No longo prazo, essa é a variável que sempre inspirará preocupação. Embora a grande migração interna da segunda metade do século XX (campo-cidade e inter-regional tenha diminuído consideravelmente, os fluxos intra-regionais continuam a ser importantes. Outros processos de mobilidade, especialmente a migração pendular e o turismo, também afetam a integridade de recursos naturais e terão de ser avaliados continuamente. O zoneamento ecológico-econômico, com seus impactos sobre a mobilidade populacional, será um requisito básico do século XXI.This article reviews research on population and environment, with particular emphasis on the Brazilian case. Attention is focused on the relations between patterns of population mobility and environmental change. With mortality and fertility rates already having experienced major transitions and now experiencing slower change, migration becomes the central factor in population change and its impacts on the environment. In the long term, this is the variable which will always inspire concern. Although the major internal migration in the second half of the 20th century (rural-urban and inter-regional has slowed considerably, intra-regional moves continue to be important. Other mobility processes, especially commuting and tourism, also affect the integrity of natural resources and must be continually evaluated. Ecological-economic zoning, and its impacts on population movements, will be a basic requirement of the 21st century.

    2001-08-01

    The purpose of this research is to study the trajectory of the environmental question in the planning of government policies. For this, the historic process of the emergence and institutionalization of the debate over the environment in the electric sector was redeemed, mainly observing the changes that occurred in the organizational and planning structure of projects. The electric sector is understood to be comprised of the network of interests and social relationships that sustain the set of policies whose principle axis is the generation, transmission and distribution of energy; this network may or may not be extrapolated beyond the design of its institutional structure. During the course of the studies carried out to prepare this thesis, the environmental question was understood, at least in a preliminary fashion, to consist of a general set of problems, diagnoses, situations, plans, programs and actions, as are institutional forms that explicitly refer to the environment as their subject, cause or objective for being or their justification. The research that the work presented here was based upon was oriented by methodological procedures that are characteristic of institutional analyses and representation studies, and used documentation available about and produced by the Electric Sector as a source of information as well as interviews and questionnaires with people directly or indirectly involved with the topic. This procedure allowed for the observation that the treatment of the environmental question in the electric sector underwent moments that varied according to the level of internalization during the different stages of the sector's projects, as well as during the formulation of its institutional policy.

    Maternal ambient air pollution exposure is associated with reduced birthweight. Few studies have examined the effect on growth in utero and none have examined the effect of exposure to particulates less than 2.5µm (PM 2.5 ) and possible effect modification by smoking status. Examine the effect of maternal exposure to ambient concentrations of PM 10 , PM 2.5 and nitrogen dioxide (NO 2 ) for in utero fetal growth, size at birth and effect modification by smoking status. Administratively acquired second and third trimester fetal measurements (bi-parietal diameter, femur length and abdominal circumference), birth outcomes (weight, crown heel length and occipito-frontal circumference) and maternal details were obtained from routine fetal ultrasound scans and maternity records (period 1994-2009). These were modelled against residential annual pollution concentrations (calendar year mean) adjusting for covariates and stratifying by smoking status. In the whole sample (n=13,775 pregnancies), exposure to PM 10 , PM 2.5 and NO 2 was associated with reductions in measurements at birth and biparietal diameter from late second trimester onwards. Among mothers who did not smoke at all during pregnancy (n=11,075), associations between biparietal diameter and pollution exposure remained significant but were insignificant among those who did smoke (n=2700). Femur length and abdominal circumference were not significantly associated with pollution exposure. Fetal growth is strongly associated with particulates exposure from later in second trimester onwards but the effect appears to be subsumed by smoking. Typical ambient exposures in this study were relatively low compared to other studies and given these results, it may be necessary to consider reducing recommended "safe" ambient air exposures.

    The resolution of a 33+-3 μm microprobe focussed with quadrupole doublet installed at the 3 MV Van de Graaff of the National Institute of Radiological Sciences, Japan, was used for the present analysis. Brown algae, Hizikia fusiforme was the sample target bombarded with a 2 MeV proton beam collimated mechanically into a rectangular image of 100 μm x 700 μm. Scanning across the sample target prepared into a longitudinal section from the caulis of the algae provided the following observations. More than 12 elements such as Al, Si, P, Cl, Ca, Mn, Fe, Cu, Zn, As, Br and Sr were determined simultaneously, together with their distributional information across the diameter. In the medullary layer, Mn and Zn were specific in their accumulation, while the deposition of Fe, Cu, As and Br were observed to be high in the epithelial layer, especially Fe and Cu which were found on the surface, where they contacted ambient sea water, but no significant change in pattern was indicated for such elements as Al, P and Cl. The PIXE microprobe analysis was, therefore, effective in its detectability for elements below a few ppm level, resultantly providing further possibilities for collecting information from bio-medical and environmental samples on trace characterization of elements.

    Non-dispersive infrared (NDIR) sensors are a low-cost way to observe carbon dioxide concentrations in air, but their specified accuracy and precision are not sufficient for some scientific applications. An initial evaluation of six SenseAir K30 carbon dioxide NDIR sensors in a lab setting showed that without any calibration or correction, the sensors have an individual root mean square error (RMSE) between ˜ 5 and 21 parts per million (ppm) compared to a research-grade greenhouse gas analyzer using cavity enhanced laser absorption spectroscopy. Through further evaluation, after correcting for environmental variables with coefficients determined through a multivariate linear regression analysis, the calculated difference between the each of six individual K30 NDIR sensors and the higher-precision instrument had an RMSE of between 1.7 and 4.3 ppm for 1 min data. The median RMSE improved from 9.6 for off-the-shelf sensors to 1.9 ppm after correction and calibration, demonstrating the potential to provide useful information for ambient air monitoring.

    2011-01-01

    An ambient temperature oxygen microsensor, based on a Nafion polymer electrolyte, has been developed and was microfabricated using thin-film technologies. A challenge in the operation of Nafion-based sensor systems is that the conductivity of Nafion film depends on the humidity in the film. Nafion film loses conductivity when the moisture content in the film is too low, which can affect sensor operation. The advancement here is the identification of a method to retain the operation of the Nafion films in lower humidity environments. Certain salts can hold water molecules in the Nafion film structure at room temperature. By mixing salts with the Nafion solution, water molecules can be homogeneously distributed in the Nafion film increasing the film s hydration to prevent Nafion film from being dried out in low-humidity environment. The presence of organics provides extra sites in the Nafion film to promote proton (H+) mobility and thus improving Nafion film conductivity and sensor performance. The fabrication of ambient temperature oxygen microsensors includes depositing basic electrodes using noble metals, and metal oxides layer on one of the electrode as a reference electrode. The use of noble metals for electrodes is due to their strong catalytic properties for oxygen reduction. A conducting polymer Nafion, doped with water-retaining components and extra sites facilitating proton movement, was used as the electrolyte material, making the design adequate for low humidity environment applications. The Nafion solution was coated on the electrodes and air-dried. The sensor operates at room temperature in potentiometric mode, which measures voltage differences between working and reference electrodes in different gases. Repeat able responses to 21-percent oxygen in nitrogen were achieved using nitrogen as a baseline gas. Detection of oxygen from 7 to 21 percent has also been demonstrated. The room-temperature oxygen micro sensor developed has extremely low power

    Childhood exposure to environmental particulates increases the risk of development of asthma. The underlying mechanisms might include oxidant injury to airway epithelial cells (AEC. We investigated the ability of ambient environmental particulates to contribute to sensitization via the airways, and thus to the pathogenesis of childhood asthma. To do so, we devised a novel model in which weanling BALB/c mice were exposed to both ambient particulate pollutants and ovalbumin for sensitization via the respiratory tract, followed by chronic inhalational challenge with a low mass concentration of the antigen. We also examined whether these particulates caused oxidant injury and activation of AEC in vitro. Furthermore, we assessed the potential benefit of minimizing oxidative stress to AEC through the period of sensitization and challenge by dietary intervention. We found that characteristic features of asthmatic inflammation developed only in animals that received particulates at the same time as respiratory sensitization, and were then chronically challenged with allergen. However, these animals did not develop airway hyper-responsiveness. Ambient particulates induced epithelial injury in vitro, with evidence of oxidative stress and production of both pro-inflammatory cytokines and Th2-promoting cytokines such as IL-33. Treatment of AEC with an antioxidant in vitro inhibited the pro-inflammatory cytokine response to these particulates. Ambient particulates also induced pro-inflammatory cytokine expression following administration to weanling mice. However, early-life dietary supplementation with antioxidants did not prevent the development of an asthmatic inflammatory response in animals that were exposed to particulates, sensitized and challenged. We conclude that injury to airway epithelium by ambient environmental particulates in early life is capable of promoting the development of an asthmatic inflammatory response in sensitized and antigen-challenged mice. These

    Surface structure, mobility, and composition of transition metal catalysts were studied by high-pressure scanning tunneling microscopy (HP-STM) and ambient-pressure X-ray photoelectron spectroscopy (AP-XPS) at high gas pressures. HP-STM makes it possible to determine the atomic or molecular rearrangement at catalyst surfaces, particularly at the low-coordinated active surface sites. AP-XPS monitors changes in elemental composition and chemical states of catalysts in response to variations in gas environments. Stepped Pt and Cu single crystals, the hexagonally reconstructed Pt(100) single crystal, and Pt-based bimetallic nanoparticles with controlled size, shape and composition, were employed as the model catalysts for experiments in this thesis.

    Due to its ultrahigh electron transmissivity in a wide electron energy range, molecular impermeability, high electrical conductivity and excellent mechanical stiffness, suspended graphene membranes appear to be a nearly ideal window material for in situ (in vivo) environmental electron microscopy of nano- and mesoscopic objects (including bio-medical samples) immersed in liquids and/or in dense gaseous media. In this paper, taking advantage of a small modification of the graphene transfer protocol onto metallic and SiN supporting orifices, reusable environmental cells with exchangeable graphene windows have been designed. Using colloidal gold nanoparticles (50 nm) dispersed in water as model objects for scanning electron microscopy in liquids as proof of concept, different conditions for imaging through the graphene membrane were tested. Limiting factors for electron microscopy in liquids, such as electron beam induced water radiolysis and damage of the graphene membrane at high electron doses, are discussed.

    The preparation and observations of spheroplast W303 cells are described with Environmental Scanning Electron Microscope (ESEM). The spheroplasting conversion was successfully confirmed qualitatively, by the evaluation of the morphological change between the normal W303 cells and the spheroplast W303 cells, and quantitatively, by determining the spheroplast conversion percentage based on the OD 800 absorbance data. From the optical microscope observations as expected, the normal cells had an oval shape whereas spheroplast cells resemble a spherical shape. This was also confirmed under four different mediums, that is, yeast peptone-dextrose (YPD), sterile water, sorbitol-EDTA-sodium citrate buffer (SCE), and sorbitol-Tris-Hcl-CaCl 2 (CaS). It was also observed that the SCE and CaS mediums had a higher number of spheroplast cells as compared to the YPD and sterile water mediums. The OD 800 absorbance data also showed that the whole W303 cells were fully converted to the spheroplast cells after about 15 minutes. The observations of the normal and the spheroplast W303 cells were then performed under an environmental scanning electron microscope (ESEM). The normal cells showed a smooth cell surface whereas the spheroplast cells had a bleb-like surface after the loss of its integrity when removing the cell wall.

    Full Text Available A incorporação da temática ambiental na saúde pública fez florescer mais recentemente a expressão saúde ambiental, relacionada à degradação do meio ambiente na escala mundial, como reflexo da atividade humana cujas consequências afetam a saúde da população. A produção de alimentos para consumo humano, além de afetar o meio natural, pode afetar, também, a saúde humana, devido ao processo de produção e comercialização. O abate de gado bovino, uma das principais fontes de proteína animal utilizada no Brasil, embora tenha legislação reguladora, muitas vezes é uma atividade que degrada o meio ambiente e compromete a saúde dos trabalhadores da cadeia produtiva e dos consumidores. Este estudo teve como objetivo geral identificar e avaliar os riscos ao meio ambiente e a saúde humana em decorrência da implantação e operação de matadouros públicos nos 75 municípios do Estado de Sergipe. Para o alcance desse objetivo, foram quantificados os matadouros municipais implantados e em operação no Estado, analisadas as condições físicas, sanitárias e tecnológicas, a existência de licenciamento ambiental e de supervisão veterinária do gado e das condições de abate e armazenamento da carne. Os dados foram levantados por observação direta em campo e junto ao cadastro da Administração Estadual do Meio Ambiente de Sergipe. O estudo concluiu haver danos significativos ao meio natural, especialmente aos recursos hídricos e risco bastante alto à saúde dos trabalhadores no matadouro e dos consumidores que recebem um produto sem controle de qualidade e sem qualquer tipo de inspeção sanitária.The incorporation of environmental issues to the public health field resulted, more recently, in the flourishing of the term environmental health, which is related to environmental degradation on a global scale, as a result of human activity whose consequences affect population's health.

Proponemos abordar estos problemas desde la relación que existe entre los principios de Competencia Judicial Civil Internacional y los principios de protección del medioambiente. Así, advertiremos que la mayor o menor extensión del fuero "lugar del hecho dañoso", adquiere connotaciones especiales si interpretamos armónicamente los principios de competencia judicial internacional y los principios de protección internacional del medio ambiente. En efecto, la política de protección ambiental, constituye un "valor superior del ordenamiento", y por tanto incide directamente en el juicio razonabilidad que el juez debe realizar sobre el vínculo de conexión.

  4. The impact of ambient dose rate measuring network and precipitation radar system for detection of environmental radioactivity released by accident

    2003-01-01

    For the surveillance of environmental radioactivity, the German measuring network of BfS consists of more than 2000 stations where the ambient gamma dose rate is continuously measured. This network is a helpful tool to detect and localise enhanced environmental contamination from artificial radionuclides. The threshold for early warning is so low, that already an additional dose rate contribution of 0,07 μGy/h is detectable. However, this threshold is frequently exceeded due to precipitation events caused by washout of natural activity in air. Therefore, the precipitation radar system of the German Weather Service provides valuable information on the problem, whether the increase of the ambient dose rate is due to natural or man-made events. In case of an accidental release, the data of this radar system show small area precipitation events and potential local hot spots not detected by the measuring network. For the phase of cloud passage, the ambient dose rate measuring network provides a reliable database for the evaluation of the current situation and its further development. It is possible to compare measured data for dose rate with derived intervention levels for countermeasures like ''sheltering''. Thus, critical regions can be identified and it is possible to verify implemented countermeasures. During and after this phase of cloud passage the measured data of the monitoring network help to adapt the results of the national decision support systems PARK and RODOS. Therefore, it is necessary to derive the actual additional contribution to the ambient dose rate. Map representations of measured dose rate are rapidly available and helpful to optimise measurement strategies of mobile systems and collection strategies for samples of agricultural products.

    Objectives Culture and religion are important in advance care planning (ACP), yet it is not well understood how this is represented in ACP online resources. The aim of the present study was to identify the availability of Australian-based ACP websites and online informational booklets containing cultural and religious information. Methods An environmental scanning framework was used with a Google search conducted from 30 June 2015 to 5 July 2015. Eligible Australian-based ACP websites and online informational booklets were reviewed by two analysts (APS & PM) for information pertaining to at least one culture or religion. Common characteristics were agreed upon and tabulated with narrative description. Results Seven Australian-based ACP websites were identified with varying degrees of cultural and religious information. Seven Australian-based ACP informational booklets were identified addressing culture or religion, namely of Aboriginal and Torres Strait Islander (n=5), Sikh (n=1) and Italian (n=1) communities. Twenty-one other online resources with cultural and religious information were identified, developed within the context of health and palliative care. Conclusions There is no comprehensive Australian-based ACP website or informational booklet supporting ACP across several cultural and religious contexts. Considering Australia's multicultural and multifaith population, such a resource may be beneficial in increasing awareness and uptake of ACP. What is known about the topic? Health professionals and consumers frequently use the Internet to find information. Non-regulation has resulted in the proliferation of ACP online resources (i.e. ACP websites and online informational booklets). Although this has contributed to raising awareness of ACP, the availability of Australian-based ACP online resources with cultural and religious information is not well known. What does this paper add? This paper is the first to use an environmental scanning methodology to identify

    Observing reacting single atoms on the solid catalyst surfaces under controlled reaction conditions is a key goal in understanding and controlling heterogeneous catalytic reactions. In-situ real time aberration corrected environmental (scanning) transmission electron microscopy (E(S)TEM permit the direct imaging of dynamic surface and sub-surface structures of reacting catalysts. In this paper in-situ AC ETEM and AC ESTEM studies under controlled reaction environments of oxide catalysts and supported metal nanocatalysts important in chemical industry are presented. They provide the direct evidence of dynamic processes at the oxide catalyst surface at the atomic scale and single atom dynamics in catalytic reactions. The ESTEM studies of single atom dynamics in controlled reaction environments show that nanoparticles act as reservoirs of ad-atoms. The results have important implications in catalysis and nanoparticle studies

    Carboxymethyl cellulosic fibers have been increasingly used in health care, agriculture and biomedical areas. The fundamental understanding of the material under different conditions is of importance in these applications. The use of environmental scanning electron microscopy for dynamic characterization of these nonwoven materials under different conditions has been explored in this study. Dynamic tensile testing under different humidity conditions was performed in a Philips XL 30 FEG-ESEM. The relative humidity in the microscope chamber was adjusted from 10% up to 100% by controlling the specimen temperature and the chamber pressure. The tensile testing was carried out on a stage that was placed in the microscope chamber. The studies under dynamic conditions have given new insight into the kinetics of structure formation, rearrangement and breakdown that are important for the processing and product development of these fiber materials

    The Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E) is a conically scanning, dual-polarization, total power microwave radiometer flying on NASA's Aqua satellite. It has been taking global observations for more than four years. The instrument was provided by the Japan Aerospace Exploration Agency, JAXA, and it was built by Mitsubishi Electric Company. AMSR-E data provide information on the state of various hydrologic parameters in the atmosphere and on the Earth's surface. AMSR-E measures dual linearly polarized radiation (horizontal and vertical polarizations) at frequencies of 6.9, 10.7, 18.7, 36.5, and 89 GHz. These frequencies have diverse amounts of influence from a wide variety of lower atmospheric and surface variables. Examples of environmental results obtained from AMSR-E data are included. One of the most important new capabilities is global SST observations through clouds, including observations of the cold wakes behind hurricanes. The cold wake behind hurricane Katrina will be shown. A monthly, global soil moisture percentage map was developed from the AMSR-E retrievals, and as an additional benefit maps showing large RFI sources have been compiled. Maps of the snow water equivalent (SWE) and detailed maps of the Arctic sea ice will be shown.

    To complement our environmental scan of academic emergency medicine departments, we conducted a similar environmental scan of the academic pediatric emergency medicine programs offered by the Canadian medical schools. We developed an 88-question form, which was distributed to pediatric academic leaders at each medical school. The responses were validated via email to ensure that the questions were answered completely and consistently. Fourteen of the 17 Canadian medical schools have some type of pediatric emergency medicine academic program. None of the pediatric emergency medicine units have full departmental status, while nine are divisions, two are sections, and three have no status. Canadian academic pediatric emergency medicine is practised at 13 major teaching hospitals and one specialized pediatric emergency department. There are 394 pediatric emergency medicine faculty members, including 13 full professors and 64 associate professors. Eight sites regularly take pediatric undergraduate clinical clerks, and all 14 provide resident education. Fellowship training is offered at 10 sites, with five offering advanced pediatric emergency medicine fellowship training. Half of the sites have at least one physician with a Master's degree in education, totalling 18 faculty members across Canada. There are 31 clinical researchers with salary support at nine universities. Eleven sites have published peer-reviewed papers (n=423) in the past five years, ranging from two to 102 per site. Annual academic budgets range from $10,000 to $2,607,515. This comprehensive review of academic activities in pediatric emergency medicine across Canada identifies the variability across the country, including the recognition of sites above and below the national average, which may prompt change at individual sites. Sharing these academic practices may inspire sites to provide more support to teachers, educators, and researchers.

    In the wake of a nuclear incident, it is essential that you can react promptly and provide a completely reliable assessment of the radiological situation. First and foremost, it is vital that your radiation early warning system can automatically detect any man-made isotopes in the environment and identify any changes in the composition of the ambient radiation. Before appropriate countermeasures can be implemented, it is crucial that authorities have accurate information about the type of contamination and its dispersion. TechniData's spectroscopic online monitoring system will improve your existing monitoring systems, provide important information about the composition of ambient radiation during an incident, and therefore help you to make the right decisions

    For more than 40 years, the United States has produced nuclear weapons. These production activities generated both radioactive and hazardous waste and often contaminated the environment. For many years, the public was unaware of the problem and unable to do anything about it. All of this has changed. In response to recent public outcry, the former Secretary of Energy, Retired Admiral James D. Watkins, established the Office of Environmental Restoration and Waste Management (EM) in November 1989. The creation of EM was the first step toward correcting contamination problems from the past 40 years In this booklet, we at DOE, through the efforts of the students at Oak Hills High School of Cincinnati, Ohio, will introduce you to EM and encourage your involvement in this major program within the Department of Energy. [Espanol] Durante mas de 40 anos, los Estados Unidos fabricaron armamentos nucleares. Esta produccion genero residuos radiactivos y peligrosos y, en muchos casos, contaminaron el medio ambiente.

Respondiendo a crecientes protestas publicas, el ex Secretario de Energia Almirante James D. Watkins, establecio en noviembre de 1989 la Subsecretaria de Administracion Ambiental. La creacion de esta Subsecretaria fue el primer paso que dio el Departamento de Energia para corregir los problemas de contaminacion ambiental de los ultimos 40 anos.

Sua perspectiva crítica e emancipatória visa à deflagração de processos nos quais a busca individual e coletiva por mudanças culturais e sociais estão dialeticamente indissociadas. A articulação de princípios de Estado e comunidade, sob a égide da comunidade, coloca o Estado como parceiro desta no processo de transformação do status quo situado, segundo Boaventura de Souza Santos, como um "novíssimo movimento social". A tal Estado cumpre o papel de fortalecer a sociedade civil como sede da superestrutura. No campo ambiental, o Estado tem crescido em termos de marcos regulatórios sem uma capacidade operacional que condiga com a demanda em vista da redução do Estado (década de 1990 e da ausência de reformas que não sejam a do Estado mínimo. À educação ambiental cumpre, portanto, contribuir com o processo dialético Estado-sociedade civil que possibilite uma definição das políticas públicas a partir do diálogo. Nesse sentido, a construção da educação ambiental como política pública, implementada pelo Ministério da Educação e Cultura (MEC e pelo Ministério do Meio Ambiente (MMA, implica processos de intervenção direta, regulamentação e contratualismo que fortalecem a articulação de diferentes atores sociais (nos âmbitos formal e não formal da educação e sua capacidade de desempenhar gestão territorial sustentável e educadora, formação de educadores ambientais, educomunicação socioambiental e outras estratégias que promovam a educação ambiental crítica e emancipatória. As políticas públicas em educação ambiental implicarão uma crescente capacidade do Estado de responder, ainda que com mínima intervenção direta, às demandas que surgem do conjunto articulado de instituições atuantes na educação ambiental crítica e emancipatória.Environmental

    Environmental scanning electron microscopy (ESEM) allows the examination of hydrated and dried specimens without a conductive metal coating which could be advantageous in the imaging of biological and medical objects. The aim of this study was to assess the performance and benefits of wet-mode and low vacuum ESEM in comparison to high vacuum scanning electron microscopy (SEM) using the choroid plexus of chicken embryos as a model, an organ of the brain involved in the formation of cerebrospinal fluid in vertebrates. Specimens were fixed with or without heavy metals and examined directly or after critical point drying with or without metal coating. For wet mode ESEM freshly excised specimens without any pre-treatment were also examined. Conventional high vacuum SEM revealed the characteristic morphology of the choroid plexus cells at a high resolution and served as reference. With low vacuum ESEM of dried but uncoated samples the structure appeared well preserved but charging was a problem. It could be reduced by a short beam dwell time and averaging of images or by using the backscattered electron detector instead of the gaseous secondary electron detector. However, resolution was lower than with conventional SEM. Wet mode imaging was only possible with tissue that had been stabilized by fixation. Not all surface details (e.g. microvilli) could be visualized and other structures, like the cilia, were deformed. In summary, ESEM is an additional option for the imaging of bio-medical samples but it is problematic with regard to resolution and sample stability during imaging. Copyright © 2011 Elsevier GmbH.

    Introduction In a 2015 report, the Institute of Medicine (IOM; Washington, DC USA), now the National Academy of Medicine (NAM; Washington, DC USA), stated that the field of Emergency Medical Services (EMS) exhibits signs of fragmentation; an absence of system-wide coordination and planning; and a lack of federal, state, and local accountability. The NAM recommended clarifying what roles the federal government, state governments, and local communities play in the oversight and evaluation of EMS system performance, and how they may better work together to improve care. This systematic literature review and environmental scan addresses NAM's recommendations by answering two research questions: (1) what aspects of EMS systems are most measured in the peer-reviewed and grey literatures, and (2) what do these measures and studies suggest for high-quality EMS oversight? To answer these questions, a systematic literature review was conducted in the PubMed (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA), Web of Science (Thomson Reuters; New York, New York USA), SCOPUS (Elsevier; Amsterdam, Netherlands), and EMBASE (Elsevier; Amsterdam, Netherlands) databases for peer-reviewed literature and for grey literature; targeted web searches of 10 EMS-related government agencies and professional organizations were performed. Inclusion criteria required peer-reviewed literature to be published between 1966-2016 and grey literature to be published between 1996-2016. A total of 1,476 peer-reviewed titles were reviewed, 76 were retrieved for full-text review, and 58 were retained and coded in the qualitative software Dedoose (Manhattan Beach, California USA) using a codebook of themes. Categorizations of measure type and level of application were assigned to the extracted data. Targeted websites were systematically reviewed and 115 relevant grey literature documents were retrieved. A total of 58 peer-reviewed articles met inclusion

  1. Environmental scanning electron microscopy study of the interaction of carbon nanotubes with fluids

    Rossi, Maria Pia

    The behavior of fluids at the nanoscale is currently of interest, as nanotechnology promises tools for the precise delivery and analysis of minute volumes of liquids. Because of their reported properties, ease of manipulation and hollow cavity, carbon nanotubes have attracted attention for fluidic delivery. Thus far, experimental studies on wetting of carbon nanotubes have been limited, and other work revolves around theoretical modeling. Consequently, there is a considerable lack of experimental data on the subject. In this work, environmental scanning electron microscopy was employed for visualization of the interaction of carbon nanotubes with fluids such as water, liquid crystals, and biological solutions. Carbon nanotubes of diverse surface structure and chemistry were evaluated, and hydrophobic and hydrophilic behavior was observed. Nanotubes made by catalytic chemical vapor deposition showed highly hydrophobic behavior by the formation of spherical water droplets on nanotube agglomerates. This behavior was caused by roughness of the agglomerates as well as pinning of the droplets on defects and functional groups along the walls of the nanotubes. On highly graphitic carbon nanotube agglomerates, no droplet formation was observed due to the lack of defects and terminations on the surface. Formation of "barrel" and "clam-shell" shaped droplets on individual nanotubes was also observed. Capillary condensation inside carbon nanotubes made by non-catalytic chemical vapor deposition was also observed in the environmental scanning electron microscope. Condensation was marked by the formation of a thin film of water on the inner walls of the nanotubes, followed by growth of a meniscus of low contact angle, indicating the hydrophilic nature of the nanotubes. Spontaneous elastic deformation of the nanotubes was observed upon the formation of the film due to surface tension effects. By annealing, the carbon nanotubes were graphitized, and highly hydrophobic behavior was

    Full Text Available A gestão ambiental tem se transformado num dos elementos chave dentro da gestão empresarial atual. Sistemas Integrados de Gestão posicionam num mesmo plano as questões relativas às dimensões financeiras, da qualidade e do desempenho ambiental. Dentro desse contexto, a mensuração dos custos ambientais ocupa um lugar de destaque no que tange à informação para a Gestão. Entretanto, a mensuração dos custos ambientais tem esbarrado nas limitações já reconhecidas dos instrumentos da contabilidade tradicional. Pela sua natureza, a maioria destes custos é considerada como sendo custos indiretos de fabricação e/ou custos fixos dificultando, com isso, sua identificação e correta apropriação. Com a utilização do Método do Custeio Baseado em Atividades (ABC, os custos ambientais podem ser definidos a partir da identificação e mensuração dos recursos consumidos pelas atividades de controle, preservação e recuperação ambiental. Tudo isso é possível devido às características do Método ABC, adaptando-se de uma melhor forma à identificação, medição e monitoramento dos custos ambientais. Este trabalho apresenta os resultados obtidos no projeto de construção de um sistema de monitoramento dos custos ambientais via web, utilizando para isto um banco de dados e linguagem PHP. Este sistema, chamado de Scorecard Ambiental, disponibiliza a informação relativa aos custos ambientais através da web categorizados segundo quatro classes, custos de prevenção, custos de avaliação, custos de falhas internas e custos de falhas externas e permite aos usuários acompanhar o comportamento dessas variáveis ao longo dos períodos.Environmental Management has become recently a central issue of corporate management.

    Full Text Available O presente trabalho discute a perspectiva de valoração ambiental a partir de fundamentos heterodoxos, numa abordagem aqui denominada institucional-ecológica. Inicia-se pela identificação das principais limitações da abordagem neoclássica e suas correspondentes proposições de valoração, particularmente tendo-se em vista o desafio posto pelo critério de Desenvolvimento Sustentável. Em seguida, busca resgatar princípios propositivos de abordagens heterodoxas, particularmente nas formulações do campo teórico institucionalista e do campo teórico da economia ecológica, como elementos de potencial integração analítica para a constituição de uma conceituação heterodoxa de valores ambientais. Por fim, o trabalho propõe, a partir de uma discussão sobre o processo de formação e internalização dos valores ambientais e desse potencial de integração analítica, bases de constituição de uma abordagem institucional-ecológica para interpretação da valoração ambiental e, dentro dessa perspectiva, discute ao final qual o escopo de aplicação dos métodos de valoração correntemente utilizados pela Economia Ambiental Neoclássica.This article discusses an environmental valuation perspective, based on heterodox foundations, in an approach here called institutional-ecological. First, it is identified the main limits of neoclassical approach and its corresponding valuation propositions, specially having in mind the challenge placed by Sustainable Development criteria. After, it seeks to bring up propositive principles from heterodox approaches, particularly from formulations in the institutionalist field and ecological economics field. These are considered elements potentially able to analytical integration for the constitution of a heterodox framework for environmental values. Finally, based on a discussion on the process of environmental values constitution and internalization and on the so claimed analytical integration

    The Direccion de Vigilancia Radiologica (DVR) of the Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) de Mexico, performs several function for environmental radiation monitoring. One of these functions is the permanent monitoring of the environmental gamma radiation. For this, it implemented the Red Nacional Automatica de Monitoreo Radiologico Ambiental (RENAMORA) - the National Automated Network for Environmental Radiation Monitoring,which currently comprises 60 detector probes for gamma radiation which with a programmable system that includes information technologies, data transmission and software can send the information in real time to a primary center of data located in the facilities of CNSNS. - When the data are received, the system performs the verification and extraction of the information organized in Tables and charts, and generates a report of environmental gamma radiation dose rate average for each of the probes and for each period of time determined bu CNSNS. The RENAMORA covers the main cities and allows to establish the bases of almost the entire country, as well as to warn about abnormal situations caused by incidents or natural events generated by human activities inside or outside the country which involves radioactive materials; paying special attention to main radiological sites, such as the surroundings of the Laguna Verde Nuclear Power Plants, research centers and the radioactive waste disposal sites.

    This work presents considerations on Ergonomics and Design for Sustainability in the healthcare field based on research experiences of the Technology and Design for Healthcare (TeDH) research group of INDACO (Industrial design, communication, arts and fashion) department of Politecnico di Milano. In order to develop a multidisciplinary approach to design able to answer to specific user needs such as elderly in an environmental sustainable way (1) this paper shows the results we achieved concerning ergonomics and environmental impact in product development (2), the extension of this approach to interior and home design and the advantage of the application of Information Communication Technologies (ICT). ICT can help people with special needs to make their everyday life easier and more safe, at the same time, ICT can make social-environmental impact of everyday behavior evident and can be applied to manage sustainability. The specific theme is thus to integrate ergonomics and sustainability competences in the development of Ambient Assisted Living through a Product- Service System approach. The concept of product service system has the potential to improve product performances and services, establish new relations and networks with different actors in order to satisfy user needs and apply a systems approach considering environmental, social and economic factors in the users' environment.

    With the coming of the Constitutional Emend n. 9/95, the Brazilian market of oil and natural gas stopped being monopolized by PETROBRAS. Since then, the concession of blocks began to be preceded by the public tender procedure realized by ANP- National Agency of Oil. The activities of oil exploration and production are potentially damaging to environment, what brings necessary the environmental licence and the previous study of the environmental impacts caused in this activity. Considering that the environmental licence must be done after the tender process, the enterprises that bought the blocks would assume the risk of not being allowed to practice their activities because of the absence of the environmental licence. To avoid that the It's offered blocks in not viable areas for oil exploration, the ANP, responsible for the public tender must accomplish a previous environmental control, to assure to the enterprises involved the environmental viability of the blocks offered. This project will touch the question of how has been realized the previous environmental control of the blocks offered by ANP into the public tender process, detaching, the control done at the 6.

    Online training for systematic review methodology is an attractive option due to flexibility and limited availability of in-person instruction. Librarians often direct new reviewers to these online resources, so they should be knowledgeable about the variety of available resources. The objective for this project was to conduct an environmental scan of online systematic review training resources and evaluate those identified resources. The authors systematically searched for electronic learning resources pertaining to systematic review methods. After screening for inclusion, we collected data about characteristics of training resources and assigned scores in the domains of (1) content, (2) design, (3) interactivity, and (4) usability by applying a previously published evaluation rubric for online instruction modules. We described the characteristics and scores for each training resource and compared performance across the domains. Twenty training resources were evaluated. Average overall score of online instructional resources was 61%. Online courses (n=7) averaged 73%, web modules (n=5) 64%, and videos (n=8) 48%. The top 5 highest scoring resources were in course or web module format, featured high interactivity, and required a longer (>5hrs) time commitment from users. This study revealed that resources include appropriate content but are less likely to adhere to principles of online training design and interactivity. Awareness of these resources will allow librarians to make informed recommendations for training based on patrons' needs. Future online systematic review training resources should use established best practices for e-learning to provide high-quality resources, regardless of format or user time commitment.

    Multidisciplinary team approach is an essential component of evidence-based wound management in the community. The objective of this study was to identify and describe community-based multidisciplinary wound care teams in Ontario. For the study, a working definition of a multidisciplinary wound care team was developed, and a two-phase field evaluation was conducted. In phase I, a systematic survey with three search strategies (environmental scan) was conducted to identify all multidisciplinary wound care teams in Ontario. In phase II, the team leads were surveyed about the service models of the teams. We identified 49 wound care teams in Ontario. The highest ratio of Ontario seniors to wound team within each Ontario health planning region was 82,358:1; the lowest ratio was 14,151:1. Forty-four teams (90%) participated in the survey. The majority of teams existed for at least 5 years, were established as hospital outpatient clinics, and served patients with chronic wounds. Teams were heterogeneous in on-site capacity of specialized diagnostic testing and wound treatment, team size, and patient volume. Seventy-seven percent of teams had members from three or more disciplines. Several teams lacked essential disciplines. More research is needed to identify optimal service models leading to improved patient outcomes. © 2014 by the Wound Healing Society.

    The evidence supporting chronic disease self-management warrants further attention. Our aim was to identify existing policies, strategies and frameworks that support self-management initiatives. This descriptive study was conducted as an environmental scan, consisting of an Internet search of government and other publicly available websites, and interviews with jurisdictional representatives identified through the Health Council of Canada and academic networking. We interviewed 16 representatives from all provinces and territories in Canada and found 30 publicly available and relevant provincial and national documents. Most provinces and territories have policies that incorporate aspects of chronic disease self-management. Alberta and British Columbia have the most detailed policies. Both feature primary care prominently and are not disease specific. Both also have provincial level implementation of chronic disease self-management programming. Canada's northern territories all lacked specific policies supporting chronic disease self-management despite a significant burden of disease. Engaging patients in self-management of their chronic diseases is important and effective. Although most provinces and territories have policies that incorporate aspects of chronic disease self-management, they were often embedded within other initiatives and/or policy documents framed around specific diseases or populations. This approach could limit the potential reach and effect of self-management.

    Full Text Available This study describes the colleters of Morinda citrifolia L. (Rubiaceae by using environmental scanning electron microscopy (ESEM and energy dispersive x-ray spectroscopy (EDS. Two different developmental stages were characterized as well as the chemical composition of secretion. Colleters are secretory structures that produce mucilage protecting the meristems and leaf primordia against desiccation and/or pathogens. Although these secretory structures are common on Rubiaceae, the results reported here is to the best of our knowledge the first record of colleters on Morinda genus. Colleters are present at the stipule adaxial surface, distributed in lines. These secretory structures are standard type and have no base constriction, differently from all studied species until now. In order to better understand the colleters structure and secretion, two phases were distinguished: a secretory phase and a senescence one. On secretory phase standard type colleters were visualized between leaf primordia and stipule, emerge on secretion. They present smooth surface, however was also possible to observe the contours of secretory cells anticlinal walls. In senescent phase colleters morphology was alternated exhibiting rough surface and blunt to point tips. The surface was rough and on stipule sections was possible to observe idioblasts with raphides bundles. The secretion process of M. citrifolia colleters occurs with the disruption of cuticle and the chemical elements are mostly dominated by carbon and oxygen.

    Although many individual studies have examined the association between temperature and blood pressure (BP), they used different methods and also their results were somewhat inconsistent. The aims of this study are to quantitatively summarize previous studies and to systematically assess the methodological issues to make recommendations for future research. We searched relevant empirical studies published before January 2016 concerning temperature and BP among adults using the MEDLINE, Embase and PubMed databases. Mean changes in systolic (SBP) and diastolic blood pressure (DBP) per 1°C reduction in temperature were pooled using a random-effects meta-analysis. Of 23 studies included, 14 were used for meta-analysis. Consistent, statistically significant, inverse associations were observed between ambient temperature (mean, maximum, minimum outdoor temperature and indoor temperature) and BP. An 1°C decrease in mean daily outdoor temperature was associated with an increase in SBP and DBP of 0.26mmHg (95% CI: 0.18-0.33) and 0.13 (95% CI: 0.11-0.16), respectively. The increase was greater in people with conditions related to cardiovascular disease. An 1°C decrease in indoor temperature was associated with 0.38mmHg (0.18-0.58) increase in SBP, while the effects on DBP were not estimated due to limited studies. Among the previous studies on temperature-BP relationship, temperature and BP measurements are not accurate enough and statistical methods need to be improved. Lower ambient temperatures seem to increase adults' BP and people with conditions related to cardiovascular disease are more susceptible to drops in temperature. Indoor temperature appeared to have a stronger effect on BP than outdoor temperature. To understand temperature-BP relationship well, a study combining repeated personal temperature exposure and ambulatory BP monitoring, applying improved statistical methods to examine potential non-linear relationship is warranted.

    Patients who undergo major surgery are at risk for perioperative morbidity and mortality. It would be appropriate to initiate advance care planning with patients prior to surgery, but surgeons may experience difficulty initiating such conversations. Rather than focus on changing clinician behavior, advance care planning decision aids can be an innovative vehicle to motivate advance care planning among surgical patients and their families. The purpose of this paper is to describe a study protocol for conducting an environmental scan concerning advance care planning decision aids that may be relevant to patients undergoing high-risk surgery. This study will gather information from written or verbal data sources that incorporate professional and lay perspectives: a systematic review, a grey literature review, key informant interviews, and patient and family engagement. It is envisioned that this study will generate three outcomes: a synthesis of current evidence, a summary of gaps in knowledge, and a taxonomy of existing advance care planning decision aids. This environmental scan will demonstrate principles of patient-centered outcomes research, and it will exemplify a pioneering approach for reviewing complex interventions. Anticipated limitations are that information will be gathered from a small sample of patients and families, and that potentially relevant information could also be missing from the environmental scan due to the inclusion/exclusion criteria. Outcomes from the environmental scan will inform future patient-centered research to develop and evaluate a new decision aid.

    Zirconium nitride is used as a selective surface for concentrated solar heating applications and one of the methods to form a zirconium nitride is texturing of zirconia surface by a high intensity laser beam under high pressure nitrogen gas environment. Laser texturing also provides hydrophobic surface characteristics via forming micro/nano pillars at the surface; however, environmental dust settlement on textured surface influences the surface characteristics significantly. In the present study, laser texturing of zirconia surface and effects of the dust particles on the textured surface in a humid air ambient are investigated. Analytical tools are used to assess the morphological changes on the laser textured surface prior and after the dust settlement in the humid air ambient. It is found that laser textured surface has hydrophobic characteristics. The mud formed during condensate of water on the dust particles alters the characteristics of the laser textured surface. The tangential force required to remove the dry mud from the textured surface remains high; in which case, the dried liquid solution at the mud-textured surface interface is responsible for the strong adhesion of the dry mud on the textured surface. The textured surface becomes hydrophilic after the dry mud was removed from the surface by a desalinated water jet.

    Nowadays, environmental indicators are widely used as effective tools to assist decision-making in both public and private sectors. The lack of literature and research about local and regional Environmental Condition Indicators (ECI), the poor knowledge regarding solid waste generation, effluents and gas emissions from foundry industries, and their particular location in the urban area of Tandil, Argentina are the main reasons for this investigation, aiming to develop a set a of ECI to provide information about the environment in relation to the foundry industry. The study involves all the foundries located in the city between March and April 2010. The set of ECI developed includes 9 indicators for air, 5 for soil and 1 for water. Specific methodology was used for each indicator. (Author) 31 refs.

    In environmental scanning electron microscopy (ESEM) high pressure applications have become increasingly important. Wet or biological samples can be investigated without time-consuming sample preparation and potential artefacts from this preparation can be neglected. Unfortunately, the signal-to-noise ratio strongly decreases with increasing chamber pressure. To evaluate the high pressure performance of ESEM and to compare different electron microscopes, information about spatial resolution and detector type is not enough. On the one hand, the scattering of the primary electron beam increases, which vanishes the contrast in images; and on the other hand, the secondary electrons (SE) signal amplification decreases. The stagnation gas thickness (effective distance the beam has to travel through the imaging gas) as well as the SE detection system depend on the microscope and for a complete and serious evaluation of an ESEM or low vacuum SEM it is necessary to specify these two parameters. A method is presented to determine the fraction of scattered and unscattered electrons and to calculate the stagnation gas thickness (θ). To evaluate the high pressure performance of the SE detection system, a method is presented that allows for an analysis of a single image and the calculation of the signal-to-noise ratio of this image. All investigations are performed on an FEI ESEM Quanta 600 (field emission gun) and an FEI ESEM Quanta 200 (thermionic gun). These methods and measurements should represent opportunities for evaluating the high pressure performance of an ESEM. © 2015 The Authors Journal of Microscopy © 2015 Royal Microscopical Society.

    The aim of this paper is to describe an optimized methodology to study the surface characteristics and internal structure of biopolymer capsules using scanning electron microscopy (SEM) in environmental mode. The main advantage of this methodology is that no preparation is required and, significantly, no metallic coverage is deposited on the surface of the specimen, thus preserving the original capsule shape and its surface morphology. This avoids introducing preparation artefacts which could modify the capsule surface and mask information concerning important feature like porosities or roughness. Using this method gelatin and mainly fatty coatings, difficult to be analyzed by standard SEM technique, unambiguously show fine details of their surface morphology without damage. Furthermore, chemical contrast is preserved in backscattered electron images of unprepared samples, allowing visualizing the internal organization of the capsule, the quality of the envelope, etc.… This study provides pointers on how to obtain optimal conditions for the analysis of biological or sensitive material, as this is not always studied using appropriate techniques. A reliable evaluation of the parameters used in capsule elaboration for research and industrial applications, as well as that of capsule functionality is provided by this methodology, which is essential for the technological progress in this domain. - Highlights: • We optimized a methodology using ESEM to analyze biopolymer capsules. • This methodology allows analyzing original surface samples without any preparation. • No preparation artefact are introduced which would mask important surface details. • Morphological details and chemical contrast from the original surface are preserved. • Capsule shape, volume, surface roughness and coating quality were reliably evaluated.

    Full Text Available Abstract Background Multi-disciplinary heart failure (HF clinics have been shown to improve outcomes for HF patients in randomized clinical trials. However, it is unclear how widely available specialized HF clinics are in Ontario. Also, the service models of current clinics have not been described. It is therefore uncertain whether the efficacy of HF clinics in trials is generalizable to the HF clinics currently operating in the province. Methods As part of a comprehensive evaluation of HF clinics in Ontario, we performed an environmental scan to identify all HF clinics operating in 2010. A semi-structured interview was conducted to understand the scope of practice. The intensity and complexity of care offered were quantified through the use of a validated instrument, and clinics were categorized as high, medium or low intensity clinics. Results We identified 34 clinics with 143 HF physicians. We found substantial regional disparity in access to care across the province. The majority of HF physicians were cardiologists (81%, with 81% of the clinics physically based in hospitals, of which 26% were academic centers. There was a substantial range in the complexity of services offered, most notably in the intensity of education and medication management services offered. All the clinics focused on ambulatory care, with only one having an in-patient focus. None of the HF clinics had a home-based component to care. Conclusions Multiple HF clinics are currently operating in Ontario with a wide spectrum of care models. Further work is necessary to understand which components lead to improved patient outcomes.

    Full Text Available Coal gangue, one of the main hazardous emissions of purifying coal from coalmine industry, is rich in silica and alumina. However, the recycling of the waste is normally restricted by less efficient techniques and low attractive output; the utilization of such waste is still staying lower than 15%. In this work, the silica aerogel materials were synthesized by using a precursor extracted from recycled silicon-rich coal gangue, followed by a single-step surface silylation and ambient pressure drying. A low density (~0.19 g/cm3 nanostructured aerogel with a 3D open porous microstructure and high surface area (~690 m2/g was synthesized, which presents a superior thermal insulation performance (~26.5 mW·m−1·K−1 of a plane packed of 4-5 mm granules which was confirmed by transient hot-wire method. This study offers a new facile route to the synthesis of insulating aerogel material by recycling solid waste coal gangue and presents a potential cost reduction of industrial production of silica aerogels.

    To subsidize its contingency plans for oil leaks, TRANSPETRO, subsidiary of PETROBRAS, set up an internal program with a big extension to obtain Environmental Sensibility Maps over a strip of twenty kilometers of width along more than five thousand kilometers of pipelines. Due to the pioneer characteristic of these natural survey (thematic cartography) it was opted a first approach for integration of this information in 1:50.000 scale. Based on a Geographical Information System (GIS), it was opted the supervised geo processing resources, compiling, firstly, the elevation, soil and geological maps for generation of the physical environment vulnerability units. Using a combination by weight average, ten vulnerability units were generated and were improved through aggregation in five units to decrease the complexity of the representation in map. These classes represent the combinations of variables of the physical environment that can be recognized by theirs corresponding landscapes. Based on interpretation of orbital LANDSAT TM images, aided by verifications in aerial photograph and a systematic survey of notable points of environmental observation (PVAs) along the pipelines, it was elaborated a general map of soil use and vegetable coverage. The classes of this theme were combined with the classes of physical vulnerability environment to generate five classes of Environmental Sensibility (Environmental Sensibility Maps). Over this theme, were attributed the representations of the main types of vegetable coverage and occupation of the soil, as well as the fauna and the other social-economics aspects, obtaining therefore a map with all the essential controller information of the environmental protection measures.

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

It was studied the response of the environmental dosemeter (DA) in fields of photonic radiation of energies W60, Wl 10, W200 and {sup 137} Cs. The irradiations were carried out following the recommendations of the standard ISO:4037. It was analyzed the response in the DA of the detectors LiF: Mg, Ti and CaF{sub 2}: Dy for the different radiation qualities and the relative response at {sup 137} Cs of both. The methodology used in the evaluation of the dose includes: the correction of the readings of both detectors by fading, gotten experimentally, the witness of transfers, the energy answer and the value of the zero. The dose is calculated applying the average pondered in uncertainty of the dose obtained for each type of detector. Its were analyzed and calculated the uncertainties that affect to the measurement following the recommendation of the Argentine standard IRAM 35050. The detection limit of the absorbed dose rate in free air of this system it is 3.5 n Gy/h for a period of sampling of 3 months.

    Experimental results of the radon detection with the equipment RAD7 are presented. The use of a solid state detector placed in a semi-spherical chamber with an electric field allows a high sensitivity of 0.4 cpm/P Ci/l. Radon detection is achieved by the spectroscopy of its decay products. In accordance with a table of errors for various ranges of counts and radon concentrations, reported by the manufacturer, an equation was obtained that allows establishing operation criteria of the equipment. For radon detection at ambient concentrations as low as 30 Bq m{sup -3}, is shown that short counts of 10 minutes are good enough to make decisions on radiation protection matter. In places where concentrations are close to 200 Bq m{sup -3}, counting intervals of the order of 0.5 hours will have an acceptable counting error of the order of 20%. The determination of radon in soil was, according to the expected, on the order of 10 kBq m{sup -3}, and was found that even with the recommended counting times of 5 minutes, there is a risk of increased humidity inside the detector above 20% Rh, with associated reduction of detection efficiency, if the desiccant is not used properly. The equipment was subjected to a radon exposure in air of 13, 373 Bq m{sup -3} ± 3.7%, contained within a controlled chamber, with a variation in temperature of (19-21) degrees Celsius and in the relative humidity of (5-7) %, the good stability of the chamber allows to propose calibration processes of these equipment s by assessing the concentration by means of a Ge (Hp) detector.

    This plan of monitoring radiological environmental routine fits on environmental policy of CNEA, satisfying national and international recommendations for licensed facilities. Sampling matrices are related to direct routes of exposure: air and water (river, lake, sediments, drinking water). Soil samples are also analyzed for having integrated matrices. They are considered as minimum three points of measurement: a white point (water or winds up), a point of maximum (water or winds down) and a point corresponding to the location of the individual representative or a point of public interest. Measurements in air estimate KERMA rate with thermoluminescent dosimeters, bi-monthly, and concentrations of particulate material and aerosols. For water samples (monthly), soil and sediments (quarterly), radionuclides that have download limits are analyzed, according to its importance in the dosages produced in the representative individual. In these cases artificial radionuclides using gamma spectrometry, beta total and Sr-90 by radiochemical techniques if the value of total screening (1 Bq/L) is exceeded. Foods are not included because no possible matrices were detected, either by their distance. by located not predominant wind direction. They are however still looking for milk producers that fulfills the minimum requirements.The data collected are compared with environmental baselines to set trends that might point to future significant changes in the environment during the life of the facilities. So far it was not observed significant differences with respect to baseline values.

    Prior to bioanalysis, sample transport and storage are critical considerations in any pharmacokinetic or toxicokinetic study design. Care must be taken to ensure the shipment is properly packaged and tracked to make certain it arrives at the desired, final destination in the appropriate timeframe, and that the integrity of the sample is not compromised. When dealing with biological specimens, environmental conditions may have a deleterious effect on the stability and conditions of the sample. Currently, frozen plasma or blood samples are the matrix of choice within the pharmaceutical industry for analysis within both preclinical and clinical trials. Liquid samples are shipped and received frozen and, therefore, the assumption is made that the frozen conditions are maintained throughout the entire transit process. Dried blood spot and dried matrix spot samples are becoming popular alternatives to plasma sampling in many small- and even large-molecule applications. With the implementation of dried blood spot and dried matrix spot samples, shipping and storage occurs under ambient conditions. In this article we discuss various shipping containers for these samples, illustrate the environmental extremes encountered during the shipping process, demonstrate a cost-effective method of monitoring both temperature and humidity, and discuss validation steps that may be implemented to minimize the impact of these variables on your study design.

    Prenatal screening tests for Down syndrome (DS) are routine in many developed countries and new tests are rapidly becoming available. Decisions about prenatal screening are increasingly complex with each successive test, and pregnant women need information about risks and benefits as well as clarity about their values. Decision aids (DAs) can help healthcare providers support women in this decision. Using an environmental scan, we aimed to identify publicly available DAs focusing on prenatal screening/diagnosis for Down syndrome that provide effective support for decision making. Data sources searched were the Decision Aids Library Inventory (DALI) of the Ottawa Patient Decision Aids Research Group at the Ottawa Health Research Institute; Google searches on the internet; professional organizations, academic institutions and other experts in the field; and references in existing systematic reviews on DAs. Eligible DAs targeted pregnant women, focused on prenatal screening and/or diagnosis, applied to tests for fetal abnormalities or aneuploidies, and were in French, English, Spanish or Portuguese. Pairs of reviewers independently identified eligible DAs and extracted characteristics including the presence of practical decision support tools and features to aid comprehension. They then performed quality assessment using the 16 minimum standards established by the International Patient Decision Aids Standards (IPDASi v4.0). Of 543 potentially eligible DAs (512 in DALI, 27 from experts, and four on the internet), 23 were eligible and 20 were available for data extraction. DAs were developed from 1996 to 2013 in six countries (UK, USA, Canada, Australia, Sweden, and France). Five DAs were for prenatal screening, three for prenatal diagnosis and 12 for both). Eight contained values clarification methods (personal worksheets). The 20 DAs scored a median of 10/16 (range 6-15) on the 16 IPDAS minimum standards. None of the 20 included DAs met all 16 IPDAS minimum standards

    Since the term biofilm has been coined almost 30 years ago, visualization has formed an integral part of investigations on microbial attachment. Electron microscopic (EM) biofilm studies, however, have been limited by the hydrated extracellular matrix which loses structural integrity with conventional preparative techniques, and under required high-vacuum conditions, resulting in a loss of information on spatial relationships and distribution of biofilm microbes. Recent advances in EM technology enable the application of Variable Pressure Scanning Electron Microscopy (VP SEM) to biofilms, allowing low vacuum and hydrated chamber atmosphere during visualization. Environmental biofilm samples can be viewed in situ, unfixed and fully hydrated, with application of gold-sputter-coating only, to increase image resolution. As the impact of microbial biofilms can be both hazardous and beneficial to man and his environment, recognition of biofilms as a natural form of microbial existence is needed to fully assess the potential role of microbial communities on technology. The integration of multiple techniques to elucidate biofilm processes has become imperative for unraveling complex phenotypic adaptations of this microbial lifestyle. We applied VP SEM as integrative technique with traditional and novel analytical techniques to (1)localize lignocellulosic microbial consortia applied for producing alternative bio-energy sources in the mining wastewater industry, (2) characterize and visualize wetland microbial communities in the treatment of winery wastewater, and (3)determine the impact of recombinant technology on yeast biofilm behavior. Visualization of microbial attachment to a lignocellulose substrate, and degradation of exposed plant tissue, gave insight into fiber degradation and volatile fatty acid production for biological sulphate removal from mining wastewater. Also, the 3D-architecture of complex biofilms developing in constructed wetlands was correlated with

Este artigo aborda a problemática da exposição à FAC por seus aspectos ligados à saúde e à poluição.Environmental tobacco smoke (ETS is a major contributor to indoor air concentrations and exposure to particles. It's known that many of its chemical compounds are toxic or carcinogens and its inhalation may cause many health injuries. Although, except in specified areas, forbidden by law, smoking in collective places is a common activity in Brazil, and, in most of the cases, specified areas, when existing, are not propriety isolated, injuring nonsmokers. Tobacco and hospitality industries maintain ventilation as a solution for this problem, but studies indicate that it is not the appropriate solution. This article approaches the ETS exposure problem through health and pollution implications.

    The environmental scan aimed to deepen our understanding of the aged care work culture and to ascertain the readiness of the workers to advance towards team-based quality care provision. The workplace context was a high-care unit within a large residential aged care facility. We used the Promoting Action on Research Implementation in Health Services (PARiHS) framework to assess workplace readiness via interviews, individual surveys and observation of practice. A profile of current culture emerged as mutually supportive and task focused, but at the same time lacking corporate team features of shared decision-making and feedback for practice improvement. However, latent within the frontline leaders and personal care staff, there was evidence of some embedded knowledge and capacity for corporate team performance. This study has validated an evidence-based method for conducting environmental scanning in aged care, recommended before any major change is introduced. Environmental scanning helps gauge workforce capacity and limitations; this information can enable managers to capitalize on identified cultural strengths to fortify change and avoid pitfalls of personal and collective vulnerabilities. © 2012 Blackwell Publishing Ltd.

  20. Issues management - Internet in environmental scanning. A strategic weapon or just another fancy toy? (situation in Finland)

    1998-01-01

    The objective of the study is to find out how different international industrial companies in Finland use the Internet as a tool in the environmental scanning process and in issues management as well. Is Internet used at all in this respect? Prime target is to find an easy way to monitor future developments via Internet and in that sense be able to forecast the future issues and develop the process of issues management. The study is descriptive and its purpose is not to shake walls but realistically describe Internet's scanning possibilities in everyday life. Communication managers in eight different Finnish companies were interviewed. Issues management and environmental scanning are parts of an organisation's strategic planning. Strategic plans are not available even for academic researchers unless the results of the study are kept secret. The level of the results of this study is therefore practical and simplistic. This chapter tells briefly some of the results gained from research. It seems that at least big forest companies use Internet a lot but because of the strategic matters involved they did not reveal all their scanning details. In general it seems that communication managers in Finland don't yet use all the available possibilities that the Internet can offer to the process of environmental scanning. Internet is still quite a new tool. Traditional information gathering techniques are still more appreciated, for instance personal contacts with environmental activists are highly valued and a common way to get information about the future events. The culture of environmental activism in Finland has moved towards quite an open direction recently. Activists can call the companies' information personnel to let them know that they are going to demonstrate in the backyard of a company and invite international press to film the show - the actions are open. There are some militant groups, however, that operate differently and hints about their actions and current

    A new method for the determination of ethanol in aqueous environmental matrixes at nanomolar concentrations is presented and compared to an existing method that has been optimized for low-level alcohol determinations. The new analysis is based upon oxidation of ethanol by the enzyme alcohol oxidase obtained from the yeast Hansenula sp. which quantitatively produces acetaldehyde after reaction for 120 min at 40 °C and pH 9.0. The acetaldehyde reacts with 2,4-dinitrophenylhydrazine forming a hydrazone that is separated from interfering substances and quantified by high-performance liquid chromatography (HPLC) with UV detection at 370 nm. Comparison of initial acetaldehyde concentration with that after enzymatic oxidation yields the ethanol concentration with a corresponding detection limit of 10 nM. Analytical results were verified by intercomparison with a completely independent technique utilizing a solid-phase microextraction (SPME) Carboxen/PDMS SPME fiber. A 12 mL aqueous phase sample was heated at 50 °C for 10 min prior to loading onto the SPME fiber. Extraction of ethanol was performed by introducing the fiber into the headspace above a pH 4.4 buffered sample containing 30% NaCl for 20 min. Samples were agitated during heating and extraction by magnetic stirring at a rate of 750 rpm. The fiber was thermally desorbed for 1 min at 230 °C in the injection port of a gas chromatograph equipped with a flame ionization detector (FID) set at 250 °C. The resulting ethanol detection limit is 19 nM. Results of an intercomparison study between the enzymatic and SPME analyses produced a trend line with a slope of unity demonstrating that methods produced statistically equivalent ethanol concentrations in several natural waters including rainwater, fresh surface waters, and sediment pore waters.

Billions of people living in low- and middle-income countries continue to be afflicted by preventable diseases due to modifiable environmental exposures, causing needless suffering and perpetuating a cycle of poverty. Current processes of economic development, while alleviating many social and health problems, are increasingly linked to environmental health threats, ranging from air pollution and physical inactivity to global climate change. Sustainable development practices attempt to reduce environmental impacts and should, in theory, reduce adverse environmental health consequences compared to traditional development. Yet these efforts could also result in unintended harm and impaired economic development if the new "Green Economy" is not carefully assessed for adverse environmental and occupational health impacts. The environmental health community has an essential role to play in underscoring these relationships as international leaders gather to craft sustainable development policies.A Conferência da ONU Rio +20 sobre desenvolvimento sustentável representa uma oportunidade crucial para colocar a saúde ambiental à frente da agenda de desenvolvimento sustentável.

    The availability and effectiveness of decision aids (DAs) on early abortion methods remain unknown, despite their potential for supporting women's decision making. To describe the availability, impact and quality of DAs on surgical and medical early abortion methods for women seeking induced abortion. For the systematic review, we searched MEDLINE, Cochrane Library, CINAHL, EMBASE and PsycINFO. For the environmental scan, we searched Google and App Stores and consulted key informants. For the systematic review, we included studies evaluating an early abortion method DA (any format and language) vs a comparison group on women's decision making. DAs must have met the Stacey et al (2014). Cochrane review definition of DAs. For the environmental scan, we included English DAs developed for the US context. We extracted study and DA characteristics, assessed study quality using the Effective Practice and Organization of Care risk of bias tool and assessed DA quality using International Patient Decision Aid Standards (IPDAS). The systematic review identified one study, which found that the DA group had higher knowledge and felt more informed. The evaluated DA met few IPDAS criteria. In contrast, the environmental scan identified 49 DAs created by non-specialists. On average, these met 28% of IPDAS criteria for Content, 22% for Development and 0% for Effectiveness. Research evaluating DAs on early abortion methods is lacking, and although many tools are accessible, they demonstrate suboptimal quality. Efforts to revise existing or develop new DAs, support patients to identify high-quality DAs and facilitate non-specialist developers' adoption of best practices for DA development are needed. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    Calibration of in situ analysers of air pollutants is usually done with dry standards. In this paper, the influence of sample temperature and environmental humidity on benzene measurements by gas chromatography coupled with a photoionisation detector (GC-PID) is studied. Two reference gas mixtures (40 and 5 µg m-3 nominal concentration benzene in air) were subjected to two temperature cycles (20/5/20 °C and 20/35/20 °C) and measured with two identical GC-PIDs. The change in sample temperature did not produce any significant change in readings. Regarding ambient humidity, the chromatographs were calibrated for benzene with dry gases and subjected to measure reference standards with humidity (20 and 80 % at 20 °C). When measuring a concentration of 0.5 µg m-3 benzene in air, the levels of humidity tested did not produce any significant interference in measurements taken with any of the analysers. However, when measuring a concentration of 40 µg m-3, biases in measurements of 18 and 21 % for each respective analyser were obtained when the relative humidity of the sample was 80 % at 20 °C. Further tests were carried out to study the nature of this interference. Results show that humidity interference depends on both the amount fractions of water vapour and benzene. If benzene concentrations in an area are close to its annual limit value (5 µg m-3), biases of 2.2 % can be expected when the absolute humidity is 8.6 g cm-3 - corresponding to a relative humidity of 50 % at 20 °C. This can be accounted for in the uncertainty budget of measurements with no need for corrections. If benzene concentrations are above the annual limit value, biases become higher. Thus, in these cases, actions should be taken to reduce the humidity interference, as an underestimation of benzene concentrations may cause a mismanagement of air quality in these situations.

    Full Text Available Todo projeto industrial, desenvolvimento urbano ou oferta de serviço implica modificações em seu entorno, um impacto ambiental que pode afetar mais do que o local físico. Essas mudanças podem ser gestionadas positivamente, para minimizar seu impacto, ou podem ser ignoradas, deixando que o meio alterado (físico e social siga seu curso, normalmente em um processo de degradação cada vez mais acelerado. A forma atual de entender a gestão ambiental remete ao conjunto de ações preventivas e paliativas para minimizar os efeitos ambientais da atividade humana. A gestão ambiental é antes de tudo gestão do comportamento humano, tanto dentro como fora das organizações. A pergunta que devemos nos fazer é se a Psicologia Ambiental tem suficiente bagagem - ou se está disposta a desenvolvê-la - para fazer frente ao desafio e assumir a responsabilidade de estar presente na gestão ambiental. Este artigo revisa algumas novas propostas nesse campo.Any industrial project, urban development or service provision leads to changes in its setting - an environmental impact that can extend well beyond the immediate site. These changes can be managed positively, in an attempt to mitigate this impact, or they can be ignored allowing the transformed environment (in its physical and social aspects to continue along its path of change, often in an increasingly rapid process of degradation. Environmental management is today understood to include preventive and palliative actions aimed at minimizing the environmental impact of human activity. Environmental management is above all concerned with management of human behavior both within and outside organizations. The question that should be posed therefore is whether Environmental Psychology has sufficient experience - or whether is willing to develop it - to face the challenge and take on the responsibilities of being present within environmental management.

    Somatic embryogenesis (SE) is an important biotechnological technique used for the propagation of many pine species in vitro. However, in bog pine, one of the most endangered tree species in the Czech Republic, limitations were observed, which negatively influenced the development and further germination of somatic embryos. Although initiation frequency was very low-0.95 %, all obtained cell lines were subjected to maturation. The best responding cell line (BC1) was used and subjected to six different variants of the maturation media. The media on which the highest number of early-precotyledonary/cotyledonary somatic embryos was formed was supplemented with 121 μM abscisic acid (ABA) and with 6 % maltose. In the end of maturation experiments, different abnormalities in formation of somatic embryos were observed. For visualization and identification of abnormalities in meristem development during proliferation and maturation processes, the environmental scanning electron microscope was used. In comparison to the classical light microscope, the non-commercial environmental scanning electron microscope AQUASEM II has been found as a very useful tool for the quick recognition of apical meristem disruption and abnormal development. To our knowledge, this is the first report discussing somatic embryogenesis in bog pine. Based on this observation, the cultivation procedure could be enhanced and the method for SE of bog pine optimized.

    An outdoor soil burial test was carried out to evaluate the degradation of commercially available LDPE carrier bags in natural soil for up to 2 years. Biodegradability of low density polyethylene films in soil was monitored using both optical and scanning electron microscopy (SEM). After 7-9 months of soil exposure, microbial colonization was evident on the film surface. Exposed LDPE samples exhibit progressive changes towards degradation after 17-22 months. SEM images reveal signs of degradation such as exfoliation and formation of cracks on film leading to disintegration. The possible degradation mode and consequences on the use and disposal of LDPE films is discussed. Copyright 2010 Elsevier Ltd. All rights reserved.

Assim, a fim de criar um sistema que pudesse fornecer dados ambientais e contabilizá-los, optou-se pela realização do SICOGEA - Sistema Contábil-Gerencial Ambiental. Antes, porém, fazia-se necessário realizar uma análise de confiabilidade. Entrevistas semiestruturadas foram realizadas com profissionais de diversas áreas. Foram enviados, via e-mail, 55 instrumentos de análise, dos quais 53 retornaram, em 30 dias. Na análise empreendida verificou-se, como vantagem inicial da gestão ambiental, o envolvimento da sociedade, pois, conhecendo a realidade local, as possibilidades de solução para as questões ambientais tornam-se mais exequíveis. Percebeu-se uma relação entre as respostas aos questionários e a atividade profissional e acadêmica dos inquiridos: aqueles envolvidos mais diretamente com a área ambiental não demonstraram preocupação com lucratividade, mas aqueles voltados à área econômica entenderam que a gestão ambiental somente terá sucesso quando trouxer vantagem econômica. Percebeuse, pois, entre estes últimos, uma clara preocupação com a sobrevivência no mercado. E é nesse contexto que se insere o SICOGEA, uma nova alternativa de gestão e Contabilidade Ambiental, pois é um sistema que pode ajudar a elucidar a problemática ambiental e possibilitar o uso de tecnologias simples e eficientes, visando à preservação, ao mesmo tempo em que atende às exigências da legislação vigente. Environment has been discussed by many experts but there is not much reported on Environmental Accounting. Thus, in order to obtain a system which is capable of furnishing environmental data and registering them, SICOGEAwas created. It is an Environmental Managing and Accounting System.

El paisaje visual considera la estética y la capacidad de percepción por un observador. Para evaluar un paisaje existen diferentes métodos y procedimientos; aquí se propone un método mixto con valoración directa de subjetividad representativa y análisis posterior indirecto con análisis de componentes principales. El método propuesto intenta mejorar el problema de la subjetividad con grupos de evaluadores cuya opinión global sea representativa y es valorado con instrumentos que contienen listas de adjetivos con expresión numérica que facilita su procesamiento. En el análisis de componentes principales sí participan paneles de expertos. La técnica de valoración del paisaje es el análisis de preferencias, que parte aceptando que el valor de un paisaje está en función del número de individuos que le prefieren. También se describe un método para valorar la fragilidad del paisaje, que integrado a la valoración permite aplicar criterios de preservación y conservación. Una evaluación equivaldrá a una fotografía instantánea, que podrá ser comparada con una fotografía homóloga del futuro.

    An environmental cell with a 50-nm-thick cathodoluminescent window was attached to a scanning electron microscope, and diffraction-unlimited near-field optical imaging of unstained living human lung epithelial cells in liquid was demonstrated. Electrons with energies as low as 0.8 - 1.2 kV are sufficiently blocked by the window without damaging the specimens, and form a sub-wavelength-sized illumination light source. A super-resolved optical image of the specimen adhered to the opposite window surface was acquired by a photomultiplier tube placed below. The cells after the observation were proved to stay alive. The image was formed by enhanced dipole radiation or energy transfer, and features as small as 62 nm were resolved.

A systematic web-based environmental scan of Canadian institutions was conducted. The website of each university was examined for potential academic programs. Six core programmatic areas were determined a priori as necessary to train competent post-market drug evaluation researchers. These included biostatistics, epidemiology, pharmacoepidemiology, health economics or pharmacoeconomics, pharmacogenetics or pharmacogenomics and patient safety/pharmacovigilance. Twenty-three academic institutions were identified that had the potential to train students in post-market drug evaluation research. Overall, 23 institutions taught courses in epidemiology, 22 in biostatistics, 17 in health economics/pharmacoeconomics, 5 in pharmacoepidemiology, 5 in pharmacogenetics/pharmacogenomics, and 3 in patient safety/pharmacovigilance. Of the 23 institutions, only the University of Ottawa offered six core courses. Two institutions offered five, seven offered four and the remaining 14 offered three or fewer. It is clear that some institutions may offer programs not entirely reflected in the nomenclature used for this review. As Heath Canada moves towards a more progressive licensing framework, augmented training to increase research capacity and expertise in drug safety and effectiveness is timely and necessary.

    2015-07-14

    Currently, we lack understanding of the content, quality and impact of patient decision aids to support decision-making between medical and surgical methods of early abortion. We plan to undertake a systematic review of peer-reviewed literature to identify, appraise and describe the impact of early abortion method decision aids evaluated quantitatively (Part I), and an environmental scan to identify and appraise other early abortion method decision aids developed in the US (Part II). For the systematic review, we will search PubMed, Cochrane Library, CINAHL, EMBASE and PsycINFO databases for articles describing experimental and observational studies evaluating the impact of an early abortion method decision aid on women's decision-making processes and outcomes. For the environmental scan, we will identify decision aids by supplementing the systematic review search with Internet-based searches and key informant consultation. The primary reviewer will assess all studies and decision aids for eligibility, and a second reviewer will also assess a subset of these. Both reviewers will independently assess risk of bias in the studies and abstract data using a piloted form. Finally, both reviewers will assess decision aid quality using the International Patient Decision Aid Standards criteria, ease of readability using Flesch/Flesch-Kincaid tests, and informational content using directed content analysis. As this study does not involve human subjects, ethical approval will not be sought. We aim to disseminate the findings in a scientific journal, via academic and/or professional conferences and among the broader community to contribute knowledge about current early abortion method decision-making support.

    Full Text Available Currently, in the Bologna context, university teaching methods focus on the student and on a learning experience based on practical methods. Under the guidance of teachers, students in the second year of the first Environmental Health Course at the Polytechnic Institute of Beja have designed and developed the following nine community intervention projects relating to environmental health: dangerous products (mercury; habitability and geriatrics; health education and the environment; drinking water; information and communication in environmental health; efficient use of resources in public buildings; child development in outdoor spaces; and allergenic factors in housing. This pedagogical action takes place over three semesters, corresponding to the three distinct phases: design, implementation and evaluation / dissemination. To ensure the viability of the projects, each group of three students has established partnerships with various entities, such as city and parish councils, hospitals, schools, consumer cooperatives, companies dealing with hazardous waste, the Youth Institute and other commercial enterprises. Although it has not been possible to evaluate the whole project, preliminary results suggest that the planned activities have been very successful, with health benefits for the people involved, through environmental improvements or an increase in empowerment. It was also possible to achieve economic gains and contribute to the conservation of the environment. The students were able to gain skills and knowledge in a teaching model characterized by the absence of lectures in which students, assisted by teachers, take decisions and independent action, simulating a real context of professional practice. This experience suggests that, by utilizing the Bologna method, the polytechnic institutions may improve their real contribution to the health of communities.Actualmente y en el marco del Plan de Bolonia, las actividades docentes

  16. Maternal and ambient environmental effects of light on germination in Plantago lanceolata: correlated responses to selection on leaf length

    International Nuclear Information System (INIS)

    Hinsberg, A. van

    1998-01-01

    1. Seeds from artificial selection lines were exposed to different maternal and ambient conditions, simulating sunlight and vegetation shade. 2. Lines selected for longer leaves also produced larger seeds, indicating a positive genetic correlation between leaf length and seed size. 3. Light conditions during maturation had no large effect on seed size. 4. Seed germination was reduced by a low ratio of red to far-red light (R/FR ratio) in the ambient environment. 5. Seeds maturated under simulated vegetation shade germinated less readily and were more inhibited by a low ambient R/FR ratio than seeds maturated under full sunlight or R/FR-neutral shade. Thus, low R/FR-ratios in the maternal and ambient environment operated synergistically. 6. Large genotypic variation in the germination responses to both maternal and ambient light conditions was found among and within selection lines, indicating that such responses might have the potential to evolve in response to natural selection. 7. Artificial selection for leaf length had affected seed germination characteristics but correlated responses and thus genetic correlations largely depended on light conditions in the selective environment. Selection for longer leaves under a low R/FR ratio increased seed dormancy and plasticity of germination in response to the R/FR ratio. However, in the opposite selective environment selection for longer leaves reduced seed dormancy and plasticity to the R/FR ratio. It is argued that leaf length and seed germination characteristics are somehow linked by shared physiological mechanisms, which may facilitate concerted changes in shade avoidance responses

    To evaluate the hydrogen (H)-induced embrittlement in iron aluminium intermetallics, especially the one with stoichiometric composition of 50 at.% Al, a novel in situ micro-cantilever bending test was applied within an environmental scanning electron microscope (ESEM), which provides both a full process monitoring and a clean, in situ H-charging condition. Two sets of cantilevers were analysed in this work: one set of un-notched cantilevers, and the other set with focused ion beam-milled notch laying on two crystallographic planes: (010) and (110). The cantilevers were tested under two environmental conditions: vacuum (approximately 5 × 10-4 Pa) and ESEM (450 Pa water vapour). Crack initiation at stress-concentrated locations and propagation to cause catastrophic failure were observed when cantilevers were tested in the presence of H; while no cracking occurred when tested in vacuum. Both the bending strength for un-notched beams and the fracture toughness for notched beams were reduced under H exposure. The hydrogen embrittlement (HE) susceptibility was found to be orientation dependent: the (010) crystallographic plane was more fragile to HE than the (110) plane. This article is part of the themed issue 'The challenges of hydrogen and metals'.

    Full Text Available As cidades estão crescendo, expandindo suas fronteiras e população. O aumento indiscriminado da industrialização e urbanização nos últimos anos tem afetado o número de construções urbanas e, conseqüentemente, provocado degradações e impactos ambientais. Desta forma, a cidade introduz modificações climáticas, sendo portanto, o clima urbano um exemplo da modificação do clima local pelo homem. Repensar tal questão hoje é refletir sobre a qualidade de vida na cidade, permitindo o controle do conforto ambiental, do consumo energético e dos impactos ambientais. Os centros históricos são objetos de discussão neste contexto, pois passam por processos de revitalização sem considerar as condições de conforto, fato que pressupõe a análise ambiental como alternativa para estudo. Desta forma, a pesquisa estuda as condições de conforto ambiental sob um enfoque bioclimático no bairro da Ribeira, o qual guarda a história da cidade de Natal/RN. Ainda pouco se estabelecem estudos de caso sobre a questão da bioclimatologia em centros urbanos no Brasil. Assim, propõe-se discutir e analisar dados das variáveis ambientais registrados no bairro, como forma de adicionar o estudo do conforto ambiental à preocupação de revitalização e preservação do centro histórico que ali se encontra, buscando o desenvolvimento urbano sustentável.The increase in industrial and housing developments have affected the total number of urban constructions and thereby negatively impacted the local environment. Examining this process we see how man has the ability to change local climate by altering his habitat. We must concern ourselves with this and allow regulations on energy consumption, environmental luxuries as well as urban comfort. This paper supports this phenomenon by examining the environmental comfort conditions in the Ribeira quarter, which holds the history of the birth of Natal/RN, using methods that propose bioclimatic analysis

    The aim of this study was to assess ex vivo the erosive effects of passive ultrasonic irrigation versus irrigation with reciprocating activation on the dentinal surface of the root canal at 3 predetermined levels using environmental scanning electron microscopy. Ten roots of mandibular premolars were prepared using the ProTaper Universal system (Dentsply Maillefer, Ballaigues, Switzerland). The specimens were embedded in flasks cleaved longitudinally, and indentations were made 3.0, 6.0, and 9.0 mm from the apex. The specimens in the control group (n = 10) were cleaned in an ultrasonic bath containing 2.5% sodium hypochlorite and 17% EDTA and then dried. Then, environmental scanning electron microscopic images were obtained at magnification × 800. The specimens were then reassembled in their flasks, and the NaOCl and EDTA solutions were activated according to the conditions established for the experimental groups (ie, the passive ultrasonic irrigation group [n = 5] and the EasyClean (Easy Equipamentos Odontológicos, Belo Horizonte, MG, Brazil) group, irrigation with reciprocating activation with the EasyClean instrument [n = 5]). The specimens of both experimental groups were analyzed in the same manner as in the control group. Analysis of the dentinal surface topography was conducted using the 3D Roughness Reconstruction program (Phenom-World BV, Eindhoven, the Netherlands) as a means for assessing erosion. The data were evaluated by means of the Kruskal-Wallis, Student-Newman-Keuls, and Mann-Whitney tests. In the EasyClean group, the degree of dentinal erosion at 3.0 mm was significantly higher than at 9.0 mm. In the other comparisons, there was no statistically significant difference (P < .05). The final irrigation techniques tested were equivalent in relation to the degree of erosion caused to the dentinal surface. Copyright © 2016 American Association of Endodontists.

    Leaf surfaces of non-tissue-cultured, vitrified and non-vitrified plantlets of Gypsophila paniculata (Babies Breath) were examined using an environmental scanning electron microscope. Non-tissue-cultured plants had a complete epidermal surface, recessed stomata and wax present on the leaf surface. The surface of tissue-cultured plantlets appeared similar to non-tissue-cultured plants excepting stomata were slightly protruding and less wax appeared to be present. In both non-tissue-cultured and tissue-cultured plants stomata were found both opened and closed and were observed closing. In contrast vitrified plantlets had abnormal, malformed stomata which appeared non-functional. The ventral surfaces of leaves seemed more normal than the dorsal, this may be due to the former receiving more light. Additionally, discontinuities were found in the epidermis. Often epidermal holes were found in association with stomatal apertures. It is suggested that the main cause of desiccation of vitrified G. paniculata plantlets ex vitro is due to loss of water from the discontinuity in epidermis and not because of non-functional stomata. Liquid water could be seen through the epidermal holes indicating that at least some of the extra water in vitrified plantlets is contained in the intercellular spaces.

In this context, PETROBRAS Research and Development Center has been expanding knowledge about the ecosystems where the company operates, providing essential information to evaluate viability and sustainability on its enterprises, as well as for environmental licensing. Reinforcing its corporative strategy, it was created in 2002 the Environmental Assessment and Monitoring Section, a group that counts nowadays with 48 professionals. This group develops technology and methodology for monitoring in social and environmental context for the petroleum industry, gas and energy, evaluating the impacts of PETROBRAS activities and products life cycle, contributing for reduction of negative effects and to improve the company's environmental management. The research areas are: land, coastal and marine ecosystems monitoring, atmospheric monitoring and air quality, environmental chemistry, ecotoxicology, social and economic evaluation and environmental damage valuation. Working partnerships with the scientific community established several contacts with Brazilian and international universities. Among these various projects related to activities in the Brazilian offshore we present some aspects of the project Campos Basin Deep Sea Environmental Monitoring. (author)

    Some new pipelines undertakings aim to establish connection between gas provinces in the Southeast and consumers in the Northeast of Brazil, in order to supply medium consuming centers and regions with minor potential of development. Consulting companies are carrying out Environmental Assessments studies and among them is the Risk Analyses of these pipeline transmission systems, in order to receive environmental permits by IBAMA, the Federal Brazilian Environmental Agency. In addition, existing interstate pipeline systems which are under IBAMA regulation will also require the same attention. For the purpose of defining a Pipeline Risk Analysis Protocol with methodology and risk criteria, with minimum risk analysis information on a comprehensive process, it has been decided for a 'tour de force' formed by experts from IBAMA and PETROBRAS engineers. The risk assessment protocol is focus on the risk to communities in the neighborhood of these pipelines and on the potential damage to the environment near and far from the ROW. The joined work ended up in two protocols, which attempt to provide environmental license permits for oil pipeline and gas pipelines with minimum contents for risk analysis studies. Another aspect is the environmental risk that has been focused on the contingency plan approach, since there are no consolidated environmental risk criteria for application as a common worldwide sense. The environmental risk mapping - MARA methodology will indicate areas with potential to be affected by leakages along a pipeline system. (author)

    The Brazilian electric energy matrix is mostly renewable. According to the Generation Information Base (BIG) of the Brazilian Electricity Regulatory Agency (ANEEL), hydroelectricity is responsible for 67.31% of the country's energy. The additional generation comes mostly from fossil fuels, whose use is questioned when it comes to environmental quality and climate change. Despite its abundance, hydroelectric power generation has physical, socioeconomic and environmental limitations. Thus, it is essential to develop alternative technologies, providing security in the supply of electric energy and the maintenance of a clean matrix. Among the alternative technologies available, wind power is the one that has been gaining prominence, domestically and internationally speaking. In the last auction of renewable sources held in August 2010 in Brazil, the energy produced by the plants of sugarcane bagasse (biomass) was traded at an average of R$ 144.20 MWh; wind energy, which was the cheapest, was traded at R$ 130.86, and the energy from small hydropower plants (PCH), at R$ 141.93 MWh. The wind power plants accounted for 70% of the auction, which resulted in a plan for increasing its installed capacity by fivefold, by the year 2013. Brazil has great potential to be explored (estimated 143,000 MW), yet despite being appealing, wind energy still face some challenges. One of them is due to the fact that most potential areas for such energy are found in permanently preservation areas and areas considered national assets, subject to special protection measures. This study aims to investigate whether the regulatory, legal and environmental issues are considered an obstacle to an effective inclusion of wind power generation in Brazil. The study examines the process of environmental licensing of wind power plants, especially those established in permanently preservation areas (APPs) and Coastal Areas. The research methodology consisted of normative framework, judicial decisions

    Research shows that vaccination against human papillomavirus (HPV) infection is one of the most effective methods for reducing risk for cervical cancer; it also protects against other HPV-related cancers. Controversies exist regarding HPV vaccination in several communities; which may in part explain why although rates of HPV vaccination are increasing nationwide, Los Angeles County (LAC) data show that many adolescents are still not vaccinated. These adolescents remain at high-risk for infection. Using community-based participatory principles, we conducted an environmental scan that included a literature review, the development of a community advisory board, community feedback from HPV community meetings, and interviews with stakeholders to understand attitudes toward HPV vaccination and their impact in follow through with HPV vaccines. Twenty-eight key stakeholders participated in our coalition comprised of community organizations and clinics with strong ties to the local community. This is the only coalition dedicated exclusively to improving HPV vaccine uptake in LAC. Of these, twenty-one participated in an environmental scan via qualitative interviews about HPV vaccination programs, service delivery priorities, and proposed steps to increase HPV vaccination uptake in LAC. The environmental scan revealed targets for future efforts, barriers to HPV uptake, and next steps for improving local HPV vaccination uptake rates. The environmental scan also identified local HPV vaccination interventions and resources. Although LAC has developed important efforts for vaccination, some interventions are no longer being implemented due to lack of funds; others have not been evaluated with sufficient outcome data. The risk for cervical and other HPV-related cancers could be greatly reduced in LAC if a multilevel, multicultural, and multilingual approach is taken to better understand rates of HPV vaccination uptake, particularly among racial/ethnic minorities and LGBTQ youth

    TO DETERMINE THE EFFICIENCY OF ERBIUM: Yttrium aluminum garnet (Er:YAG) laser with Environmental Scanning Electron Microscope (ESEM) and shear bond strength analysis as a method of recycling stainless steel orthodontic brackets and compare with other methods of recycling. Eighty samples of extracted premolar teeth bonded to SS brackets were tested for rebonded shear bond strength after recycling by four methods and compared with a control group of 20 samples. These 80 samples were randomized into four groups which were recycled by four methods, namely, sandblasting, thermal method, adhesive grinding by tungsten carbide bur, and Er: YAG laser method. After recycling, ESEM and shear bond strength analysis were used to analyze the efficiency of the recycling methods. ER: YAG laser group was found to be having the greatest bond strength among the recycled brackets (8.33±2.51 followed by the sandblasting at 6.12±1.12 MPa, thermal and electropolishing at 4.44±0.95 MPa, and lastly the adhesive grinding method at 3.08±1.07 MPa. The shear bond strength of Er: YAG laser group was found to be having no statistically significant difference with that of the control group (P>0.05 and had statistical signifance with sandblasting, thermal and electropolishing and adhesive grinding groups at P>0.001. ESEM analysis showed complete removal of adhesive from the brackets recycled with Er: YAG laser which mimicked that of the control group. ER: YAG laser (2940 nm) was found to be the most efficient method for recycling, followed by the sandblasting, thermal, and the tungsten carbide methods, which had the least shear bond strength value and is not fit for clinical usage.

    The regulation of the law no 9.985, of July 18, 2000, by the decree no 4.340, of August 22, 2002, awake the productive sector to the imposition to the entrepreneur that must destine the amount of at least 0,5% of the total costs foreseen for the hole undertaking implementation, to implement or maintain environmental conservation units. The most of the environmental agencies have been applied 0,5%. The IBAMA uses a methodology to establish the impact level and the range between 0,5% and 5% to define the environmental compensation percentage and is questionable. Then, until now, this legal requirement have been applied in a heterogeneous form to the environmental licensing. The various applied criterions, the huge subjectivity in the impact level assessment, and the influence of this requirement in the licensing schedule, associate to the oil and gas sector project costs point to a relevant impact in the feasibility of the oil and gas sector projects. Based in the percentages that IBAMA had established for the oil and gas sector was esteemed some costs destined to the environmental compensation. The law implementation without inhibition of investments in the country depends on the involved sectors articulation. (author)

    This article presents a practical case on the Life Cycle Analysis (LCA) methodology, for the incorporation of the environmental vector in the company decisions; specifically in the case of the industrial trowels. These, although they do not have a high unitary environmental production impact, they do generate an important problem to the environment, due to their extended use at industrial scale, their high annual production and the high percentage of package waste they represent (specially in the case of the wooden ones). Thus, three options for the transport of 1,000 tons of product are compared from the environmental point of view: a wooden aurotrowler, a plastic one and a cardboard one; optimizing their use, that is to say, reusing them the greater number of times.

    The methodology for a Strategic Environmental Evaluation of Natural Gas - SEA/NG incorporates within the analysis of the project the socio-cultural, economic, energetic and environmental implications of the transformations, due to the adoption of natural gas, in the area of influence of gas pipelines and gas-powered thermo-electric plants. It was based on the case study of a gas pipeline planned to reach the city of Dourados from Campo Grande, capital of the Brazilian State of Mato Grosso do Sul, which implied the construction of a thermoelectric plant in Dourados. The SEA/NG: 1. Defines the best alternative track for gas pipelines; 2. Proposes location alternatives for gas-powered thermo-electric plants; 3. Evaluates the cumulative and synergic effects of human activities in the socio-environmental aspects; 4. Studies the dynamics of regional development; 4. Supports urban planning decisions in cities housing gas-powered thermo-electric plants; 5. Proposes a System of Analysis and Environmental Monitoring for Natural Gas. Qualitative-quantitative matrixes were used to evaluate the cumulative and synergic effects of the adoption of natural gas within the regional energy matrix, determine the best alternative track for the gas pipeline proposed from Campo Grande to Dourados, and to identify the best location for a gas-powered thermo-electric plant. The matrixes integrated the areas of geology, hydrology, ecology and socio-economics issues both in the phases of construction and operation of the pipeline. Diagrams and interactive conceptual models were also used to synthesize the principal components involved in the choice of the best gas pipeline alternative track. This project received financial grants from PETROBRAS, MSGAS, TBG and FINEP. (author)

Partindo de um referencial teórico-conceitual da ecologia política, da teoria crítica e do pensamento complexo, problematiza as origens e os desdobramentos político-culturais, os argumentos e movimentos sociais que formataram essa tendência pedagógica de marcante presença na realidade educacional e ambiental brasileira. À luz desses referenciais, o artigo revisa e sistematiza a produção pertinente a esse novo campo de conhecimento e ação e, nesse sentido, dialoga, por meio desta produção, com os pesquisadores, educadores, agentes públicos e de organizações da sociedade civil que, nas décadas recentes, se envolveram com práticas e reflexões sobre a relação entre sociedade, educação e meio ambiente no Brasil. Investiga, para tanto, o debate, a diferenciação e as disputas internas ao campo da educação ambiental no Brasil, o processo de constituição do socioambientalismo que se coloca em contraposição a outra tendência conservacionista de educação ambiental e a construção de uma crítica a uma educação para o desenvolvimento sustentável, proposto pela UNESCO e demais setores interessados na conservação do status quo e numa sustentabilidade orientada pelas forças do mercado. Destaca, assim, em uma perspectiva histórica, as matrizes filosóficas, as posições político-pedagógicas e as forças sociais que inspiraram a emergência da educação ambiental crítica assim como as contribuições decisivas que esse processo legou ao avanço ético e político das relações entre a educação, a sociedade e o meio ambiente no Brasil.The article is a reflection about the historical and theoretical contexts of the creation of environmental education in Brazil, from the perspective of what came to be called Critical

La finalidad de nuestro artículo es estudiar el proceso de evolución de ambos conceptos, para empezar a construir un modelo, centrado en lo que nosotros hemos querido denominar intervención educativa socioambiental, que aúne ambas intervenciones. Desde esta perspectiva toda intervención ambiental debe tener en cuenta los aspectos educativos y sociales porque las personas, los grupos y las comunidades son los afectados y beneficiarios de las transformaciones en el entorno físico y toda intervención socioeducativa debe contemplar los aspectos ambientales implicados, puesto que ésta siempre se desarrolla en un contexto socio-físico determinado.Abstract: The concepts of socio-educational and environmental interventions have been studied as two different fields, with some overlap, but with separated and unconnected methods and strategies. The purpose of our article is to study the development of both concepts to build a model, focused on what we have named “socio-environmental educational intervention”, bringing together both concepts. From this perspective, every environmental intervention should take into account educational and social aspects as individuals, groups and communities are the beneficiaries and the ones affected by the changes in the physical environment and each socio-educational intervention should consider all environmental aspects involved, since it always take place in a certain socio physical context.

    Electric energy has an important function in the modem world; it is fundamental for progress and development. The electricity discovery allowed improvements in several areas: health, water and food supply, quality of life and sanitary conditions, and contributed also to the establishment of the capitalist and consumption society. The use of oil as an energy generation source was the impulse for the industrial revolution and machines, motors and generators were developed contributing to the progress This also brought the pollutant gases emission (CO{sub 2} , CO, SO{sub x} and NO{sub x}) and other substances that had contributed to the greenhouse effect, the ozone hole and the acid rain, modifying the balance of the planet. The development and implementation of other forms of energy generation caused local changes, where they were installed, giving rise to environmental impacts. This work presents an evaluation about different forms of electrical energy generation and the environmental impacts relative to each one of them. Five forms of electric energy generation were considered: thermoelectric, nuclear, hydroelectric, wind and solar energy. The implementation and the development of the petroleum industry in the world and in Brazil are presented. The geology of the oil, its extraction and quality improvement, besides details of the functioning of three types of thermoelectric power plants - coal, gas and oil - are also discussed. The specific as well as the environmental impacts they have in common are highlighted. The impacts originated from the deactivation of each one of them are also pointed out. The discovery and the development of nuclear energy in Brazil and in the world as well as the functioning of a nuclear power plant, the impacts generated by its operation and decommissioning are presented. The history, functioning and development of hydroelectric energy generation in Brazil, characterized by the great plants, are related to environmental aspects The

    With the necessity for new forms of energy production to contain the environmental crisis and the global warming, new technologies have been studied and the nuclear energy has been placed as one of the ways out for clean energy production. The study of the risk is directly related to the study of its perception, that determines the human being's actions, therefore it influences in new technologies applications, since the awareness of something as dangerous is determined by socio-historical factors. The purpose of this study was compare the perceptions of nuclear and environmental risks, considering a group of university students, with the application of research in the period from March 31 to May 31, 2010, containing: images of historical facts to be nominated; structuring of a risk scale for certain activities, and a questionnaire about risks and benefits related to the subject research.

    The energy and fuel obtaining process must be understand as a political concept and a socially built one. Such a process should be understood taking in account social impacts, environmental issues, land struggles. There are plenty of empirical examples able to identify flows, directions and speedy up enterprises when extracting matter and energy conversion within areas of high social and environmental sensibility. The infra-structure expansion over traditional people areas, high biodiversity mapped regions and environmental sensibility areas are expression of the capital intensive accumulation process and must be legitimated in one way or another. Simultaneously two way processes occur: in one hand the use of land, riverside areas and natural landscapes to generate electrical energy and fuel obtaining an in the other hand the abandon of original usage for the land. Specifically, in the Amazon rain forest area it is evident that the mentioned flows are supported by the natural wealthy. So, the analyses under a scientific approach, elaborating theories, demonstrations and occurrences documentation are necessary. Two preliminary expectations are posted by the article: 1) Discuss the implications due to the creation of energetic reserve areas over traditional people regions; 2) Produce a preliminary picture of demands over natural resources and respective social conflicts based on significant selected cases.

    In 2003 the INMA-INfancia y Medio Ambiente (Environment and Childhood) project, a Spanish national network of birth cohorts including more than 3500 participants, was set up with the aim to assess the health impacts of pre- and postnatal environmental exposures on children. The project has published more than 60 papers on maternal and environmental factors related to neuropsychological development in children, one of the main research interests within the project. With the present review, we evaluate the evidence provided by the INMA project on this topic and discuss how the data can contribute to cover the challenges that children's environmental health research will face in the coming years. The INMA project has contributed to provide increasing evidence of the association between prenatal exposure to persistent organic pollutants (POPs) and child neuropsychological development, but it has also shown, using innovative methodologies, that postnatal exposure to these compounds does not play a role in this association. The project has also contributed to show the detrimental influence of certain air pollutants on child neuropsychological development, as well as how a balanced maternal fish intake can protect from the potential adverse effects of prenatal exposure to mercury. Also, the project has contributed to the understanding of impacts of nutritional factors including supplement intake and vitamin D levels during pregnancy and the role of breastfeeding on the neuropsychological benefits. INMA findings underscore the importance of continued research on the delineation of the sensitive windows of exposure both during pregnancy and postnatally and on the combined effects of environmental exposures, denoted the exposome. In terms of health policy, INMA findings have important implications for the development of public health policies to advance the health and development of children. Copyright © 2017 Elsevier GmbH.

    The Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) in Mexico is a decentralized body, under the Secretaria de Energia whose main mission is to ensure that activities involving nuclear and radioactive materials as well as ionizing radiation sources are carried out with maximum security, considering the current technological developments. In order to monitor the levels of environmental radiation to which the population is exposed, the CNSNS has established a series of radiological monitoring programs that allow characterize the environmental radiation levels in each zone or region in the country; to identify the occurrence of natural or artificial radiological events, such as nuclear tests and accidents in radioactive or nuclear facilities. The National Automatic Network for Environmental Radiological Monitoring (RENAMORA) project was initiated with the support of the IAEA through MEX9/049 project and its purpose is to have a network of instruments that automatically and in real time, transmit information of the gamma radiological environmental status of the national territory and changes occurring in it. This network provides data such as the speed of ambient dose equivalent, temperature and humidity in different regions of the country. The network is composed of 92 stations that are distributed throughout the national territory. The structure of the stations has evolved since its inception, now allowing detection tasks, data transmission and managing them remotely from the main server, which is located in the CNSNS, which is performed a statistical dose for each monitoring station. Each monitoring station is formed in its current structure by a probe detection of gamma radiation, a communication module and associated electronics, a mini Web server DataGATE, a cellular modem and an interface converter.

O método de pesquisa foi o estudo de caso múltiplo. O desempenho ambiental de uma operação de manufatura foi tratado como uma grandeza intangível, composta por cinco construtos latentes: emissões atmosféricas; efluentes líquidos; resíduos sólidos; uso de recursos naturais e gestão interna; e atendimento a legislações e certificações. Os quatro primeiros são de impacto direto, enquanto que o último foi considerado condição intermediária e necessária para os demais. Os significados dos construtos foram apreendidos por indicadores e mensurados qualitativamente por questionários respondidos por gestores de cinco operações: operação avícola, fabricação mecânica, fabricação de materiais elétricos, fabricação de rações e estamparia de aço. Os resultados foram estudados e comparados e forneceram subsídios para a eventual reformulação de estratégias de ação ambientais inseridas nas estratégias de operação das empresas.This paper presents and tests a method for building models to measure environmental performance in manufacturing operations.

    Full Text Available The anisotropic structure of climatic space may cause significant (and to a large extent unappreciated non-evolutionary niche shifts. This can be seen mostly in the context of spatial transferability of ecological niche models. We explore this effect using a virtual species in the United States. We created a simple virtual species by postulating its fundamental niche as an ellipse in a two-dimensional realistic climatic space. The climatic combinations defined by the ellipse were projected in the geography of the United States and 2 regions of equal area were selected. The structure of niche in the 2 areas is compared. It is shown that the 2 regions have differently positioned subsets of the environmental space, which creates "shifts" in the realized niches despite the fact that no evolution and no biotic interactions are present. The most parsimonious hypothesis when ecological niche modeling reveals shifts in the realized niche is that environmental space is heterogeneous. Without considering differences in the structure of environmental space no speculation about niche evolution or the role of competitors should be attempted.La estructura anisotrópica del espacio climático puede causar desplazamientos significativos no evolutivos en los nichos de las especies. Este efecto poco apreciado en la literatura se manifiesta con gran claridad cuando se realizan transferencias espaciales de modelos de nicho ecológico. Se explora este efecto utilizando una especie virtual en los Estados Unidos. Se creó una especie virtual simplificada postulando su nicho fundamental en forma de una elipse en un espacio realista de 2 dimensiones. Las combinaciones climáticas definidas por la elipse se proyectaron en la geografía de los Estados Unidos y se seleccionaron 2 regiones de igual superficie espacial. Se compara la estructura del nicho en las 2 regiones, mostrando que estas 2 regiones espaciales presentan subconjuntos distintos del espacio de variables

    Full Text Available No Estado do Tocantins há um tipo de empreendimento impactante denominado de "praias fluviais". Estas surgem entre os meses de junho e setembro, exatamente quando ocorre a diminuição da vazão dos rios, o que permite o aparecimento dos bancos de areia. Nestes locais são implantadas infra-estruturas para atrair os visitantes, o que leva à descaracterização acentuada do ambiente ribeirinho. Assim, o presente trabalho teve como objetivo listar os impactos ambientais decorrentes dessas "praias fluviais", a partir da identificação e descrição de suas atividades impactantes. Lançou-se mão do método do check-list para a listagem dos impactos, enquanto a identificação e a descrição das atividades impactantes resultaram de consultas à literatura especializada e de contatos via Internet. Foram identificadas 21 atividades impactantes, sendo 10, 6 e 5 para as etapas de Implantação, Utilização e Desativação, respectivamente. Identificaram-se 35 impactos ambientais, sendo 21 (60% negativos e 14 (40% positivos. A principal conclusão é a de que o presente estudo pode ser utilizado como referencial teórico para nortear o processo de licenciamento ambiental do empreendimento denominado de "praias fluviais", no Estado do Tocantins.This work describes a type of impactant enterprise at the state of Tocantins called "Fluvial beaches." These "beaches" appear between June and September, exactly when the decrease of the discharge occurs, thus allowing the appearance of sand banks. Tourism infrastructure is implanted to attract visitors, leading to an a strong discharacterization of the riverine atmosphere. Therefore, the objective of this study was to list the environmental impacts caused by these "fluvial beaches", starting with the identification and description of their impactant activities. The check-list method was used to list the impacts, while the identification and description of the impactant activities resulted from consultations

    Full Text Available Neste artigo discute-se o trabalho com valores em Educação Ambiental, o que exige uma fundamentação e posicionamento adequados. Diante do impasse entre posições relativistas e universalistas para a educação em valores, aponta-se para a necessidade de explicitar nossa posição e ação em favor dos valores ambientalmente desejáveis, considerando que as questões envolvidas com o meio ambiente dizem respeito à vida e à sobrevivência de todos os seres do planeta. Estes valores podem ser identificados junto aos princípios presentes no "Tratado de educação global para sociedades sustentáveis e responsabilidade global", apresentado pela sociedade civil na ECO-92. Por fim, ressalta-se a necessidade de se desenvolverem estratégias educativas que envolvam as dimensões aqui denominadas de cognição, afetividade e ação, resultando em um trabalho abrangente, que amplie as possibilidades de o indivíduo apreender, de maneira mais efetiva, um dado valor, tendo, então, melhores condições de construí-lo em sua vida.In this paper we discuss the value content of Environmental Education, because it requires an adequate theoretical basis and positioning. The relativist and universalistic positions are presented and it is pointed out that the environmental questions and their respective values mean much more than simple personal options. This is because the environmental questions concern life and the survival of all living beings on the planet. Thus, we must make our position and actions consistent with these values. They are identified in the principles reported in "Treatise for the global education for sustainable societies and global responsibility", which was elaborated by the civil society at ECO-92. It is also considered that values education is an issue focusing on the dimensions of cognition, feelings and action. All these three dimensions aim at achieving a broader result.

    The European Environmental Liability Directive borrows from the US legislation the equivalency analysis tool. It is a tool to calculate the necessary remediation to return the environment to its baseline situation, as if it had not suffered the damage. The equivalence between damage and remediation can be estimated in terms of services (hectares of wetlands, for instance) or resources (trout, cork oaks), but under some circumstances the law also provides for welfare equivalency (generally expressed in monetary units). This articles introduces the equivalency tools, analyzes them in a cost-benefit analysis framework, and discuses some related issues, like the time treatment or the organization of a habitat banking system.

    Oil is one of Colombia's main richness; its exportation since 1986 has greatly contributed to the country's economic growth. But about 800 attacks to the oil pipelines system committed by the main terrorist organisations in 12 years, has been causing not only great economic losses but altos great environmental impacts in many regions of the country. This article analyses how this heavily damages the country's fragile ecosystems and bio-diversity patrimony, also affecting those social groups whose lives are strictly related to the natural resources.

    2013-01-01

    Full Text Available Recentemente, o conceito da pegada hídrica foi introduzido como um indicador importante de consumo de água para a humanidade. A pegada hídrica é definida como o volume total de água utilizado durante a produção de bens e serviços, bem como o consumo direto de água pelos seres humanos. A água não é consumida só diretamente mas também indiretamente, nos processos de produção. Portanto, o cálculo da pegada hídrica permite quantificar o total de água consumida ao longo da cadeia de fornecimento global. Esta revisão de literatura analisa o estado da arte da pegada hídrica desde a sua criação, no encontro internacional de especialista em comércio de água virtual realizado em dezembro de 2002 na Holanda, até os dias atuais. Os principais resultados encontrados na literatura consultada indicam consenso de que a pegada hídrica é capaz de monitorar o impacto humano sobre o meio ambiente. Além do mais, esta metodologia tem uma vasta gama de aplicações que pode ser empregada em escalas que vão desde um único produto, um processo, setor, individuo, cidades, até mesmo nações e todo o planeta.The concept of the water footprint has been recently introduced as an important indicator for human induced water consumption. The water footprint is defined as the total volume of water used during production and consumption of goods and services as well as direct water consumption by human beings. Water is not only consumed directly but also indirectly in production processes. Therefore, calculating the water footprint enables to quantify total water consumed along the whole global supply chain. This review surveys the state of the art on water footprint since the International Expert Meeting on Virtual Water Trade, held in Delft, The Netherlands, in December 2002, until current days. The major findings linked to the consulted literature indicated that the water footprint is suitable for monitoring the human impact on the environment

    Throughout the historic evolution of the Brazilian legislation, including a brief analysis of the prevailing laws regarding the subject, this paper provides an ample vision of the civil and environmental liability in transport contracts, and, especially, in the transport of oil and gas through pipelines, discussing the present influence of environmental norms and the New Brazilian Civil Code. And what was brought to a conclusion is, if on one hand were kept the liability of the Sender (user company of the transportation service contracted with the Carrier) and Carrier (personal entity operator of the pipeline system), who respond jointly and regardless of fault for damages to third parties and the environment (extendible also to the owner of the product and to financial institutions that participate in some form in the contract), on the other hand the New Civil Code authorizes the National Petroleum Agency - ANP to rule the liabilities between the parties to the transport contract, providing greater safety to the system operators.

    This report is the original research work presented for the attainment of the author master degree and its main objective has been the resolution -by means of friendly programming- of some of the observed problems in the environmental radioactivity laboratory belonging to the Department of Radiological Surveillance and Environmental Radioactivity from CIEMAT. The software has been developed in Visual Basic for applications in Excel files and it solves by macro orders three of the detected problems: a) calculation of characteristic limits for the measurements of the beta total and beta rest activity concentrations according to standards MARLAP, ISO and UNE and the comparison of the three results b) Pb-210 and Po-210 decontamination factor determination in the ultra-low level Am-241 analysis in air samples by alpha spectrometry and c) comparison of two analytical techniques for measuring Pb-210 in air ( direct-by gamma spectrometry- and indirect -by radiochemical separation and alpha spectrometry). The organization processes of the different excel files implied in the subroutines, calculations and required formulae are explained graphically for its comprehension. The advantage of using this kind of programmes is based on their versatility and the ease for obtaining data that lately are required by tables that can be modified as time goes by and the laboratory gets more data with the special applications for describing a method (Pb-210 decontamination factors for americium analysis in air) or comparing temporal series of Pb-210 data analysed by different methods (Pb-210 in air).

    In the heart of the Amazon forest, some 600 km from the city of Manaus, the Brazilian Oil Company - PETROBRAS - is developing the 'URUCU PROJECT'. Consisting on 3 oil and gas production fields and 3 natural gas processing plant, 2 huge pipelines crossing the dense Amazon forest and its rivers and going towards COARI - the Fluvial Terminal of Solimoes river. Then, vessels and ferries, loads LGN to the north region and oil to feed the Manaus refinery plant. In a near future natural gas pipelines will connect COARI to Manaus and URUCU to Porto Velho. The whole project will allow energy supply to the less developed and isolated region of Brazil, and brings relief for the local population, but represents one of the biggest challenges for the oil and gas industry in terms of environmental sustainability for projects in very sensitive areas. The paper concludes that it is viable to face such a challenges counting on an Environmental Management System tailored to fit the region peculiarities, including a high level of Preparedness and Response for oil incidents, and last but never least assuming a respectful attitude towards the Amazon and its people.

    The biological effects of acute particulate air pollution exposure in host innate immunity remain obscure and have relied largely on in vitro models. We hypothesized that single acute exposure to ambient or engineered particulate matter (PM) in the absence of other secondary stimuli would activate lung dendritic cells (DC) in vivo and provide information on the early immunological events of PM exposure and DC activation in a mouse model naïve to prior PM exposure. Activation of purified lung DC was studied following oropharyngeal instillation of ambient particulate matter (APM). We compared the effects of APM exposure with that of diesel-enriched PM (DEP), carbon black particles (CBP) and silver nanoparticles (AgP). We found that PM species induced variable cellular infiltration in the lungs and only APM exposure induced eosinophilic infiltration. Both APM and DEP activated pulmonary DC and promoted a Th2-type cytokine response from naïve CD4+ T cells ex vivo. Cultures of primary peribronchial lymph node cells from mice exposed to APM and DEP also displayed a Th2-type immune response ex vivo. We conclude that exposure of the lower airway to various PM species induces differential immunological responses and immunomodulation of DC subsets. Environmental APM and DEP activated DC in vivo and provoked a Th2 response ex vivo. By contrast, CBP and AgP induced altered lung tissue barrier integrity but failed to stimulate CD4+ T cells as effectively. Our work suggests that respirable pollutants activate the innate immune response with enhanced DC activation, pulmonary inflammation and Th2-immune responsiveness. PMID:21099199

    Full Text Available The main target of the present article consists in basing from a specific context the place that occupies the environmental formation in the architecture students. In university context, education for sustainability implies a process that includes political decisions which open ways to generate opportunities for democratic participation in different stratums to define the institution strategies. At the same time education for sustainability requires a strong academic compromise to incorporate sustainability criteria in the education process. As a result, it urges to generate a behavior change that develops skills to create a proper sustainability environment. For all these reasons, the new educative law cannot ignore architecture career which encourages a professional who applies resources and strategies to build knowledge, develop values and acquire creative attitudes to improve the environment. El objetivo del presente artículo consiste en fundamentar desde un contexto específico el lugar que ocupa la formación ambiental en los estudiantes de arquitectura. En el ámbito universitario la educación para la soste¬nibilidad implica un proceso, que incluye decisiones políticas, que abran el camino para la generación de espacios necesarios para la participación democrática de los diversos estamentos para la definición de las estrategias propias de la institución, a la vez que requiere un fuerte compromiso docente para incorporar los criterios de sostenibilidad en los procesos de formación. Se necesita con urgencia generar cambios en la conducta para desarrollar capacidades que creen un ambiente propicio para la sostenibilidad. La carrera de Arquitectura no escapa a la actual reforma educativa que apuesta por un profesional que encamine el uso de recursos y estrategias, para llevar a cabo la construcción de conocimientos, el desarrollo de valores y la adquisición de actitudes creativas y comprometidas en la mejora del entorno.

    Full Text Available O Brasil, mesmo com os avanços nos indicadores socioeconômicos ainda se apresenta desigual, situação fruto de um desenvolvimento historicamente excludente. Foi escolhido o Índice de Desenvolvimento Humano (IDH e indicadores sociais, econômicos, ambientais e de saúde para exemplificar essa problemática. Foram selecionados os municípios que apresentavam mais baixos IDHs no ano de 2000 e comparada sua evolução temporal entre 2000 e 2010 por meio de indicadores relacionados aos pilares econômico, ambiental e social do desenvolvimento sustentável. Estes possuem um IDH classificado como baixo (Despite its progress in terms of socio-economic indicators, Brazil is still unequal, which is due to an unequal and exclusionary historical process. In this paper we selected the Human Development Index - HDI and other social, economic, environmental and health indicators to exemplify this situation. We selected the municipalities that had the lowest HDI in the country in 2000 comparing their evolution over time between 2000 and 2010 by means of indicators linked to the economic, environmental and social pillars of sustainable development. These municipalities have an HDI classified as low (<0.500, and correspond to countries such as Laos, Yemen, Haiti and Madagascar. At national level, data for the decade show a significant improvement in economic indicators (decrease from 23% to 8.9% of people living on less than a quarter of the minimum wage; social indicators (increase from 86.5% to 90.2% of literacy in women, and the environmental indicator associated with access to the water grid, which also improved to a lesser extent (increase from 81% to 85%. It was concluded that in order to achieve sustainable development with quality of life, the improvement of sanitation and education indicators should be a priority for Brazil.

  2. A Study of Solid Oxide Fuel Cell Materials at High Temperature Using an Environmental Scanning Electron Microscope

    Jony, Mahfuzur Rahman

    Solid oxide fuel cells (SOFCs) are promising energy conversion devices, but their economic viability depends on long term stability of the SOFC materials at the high operating temperatures. The in-situ study of materials degradation faces a great challenge because of the unavailability of analytical methods at those high temperatures. The traditional analytical techniques for degradation measurements are widely based on post-mortem studies. The cells or cell materials are cooled down to room temperature and are then subjected to microscopy-based methods. Combining post-mortem analyses with cell modelling, several studies have reported the following microstructural degradations: (a) Lanthanum Strontium Manganite (LSM) particles, one of the most widely used cathode material, 'melt' or 'spread' at temperatures as low 850 °C without the presence of a current flow on Yttrium Stabilized Zirconia (YSZ) surface, (b) the Ni particle shapes change during oxidation of nickel to NiO and as a result of reduction of NiO to Ni during redox cycling, (c) the formation of nickel phosphide particles on the Ni/YSZ anode surface due to the presence of PH3 in coal syngas. However, these reports are limited due to the fact that analyses were done at room temperature rather at their high operating temperature. In this current study, cell materials were examined in-situ at high temperature using an Environmental Scanning Electron Microscope installed with a heating stage. High temperature images were collected for different cell materials such as silver paste, LSM particles, nickel oxide particles and secondary nickel phosphide phase formed on YSZ substrate. The images were analyzed by using ImageJ, an open source image processing software. An image analysis protocol was developed to analyze the cell materials images taken from 500 °C to 1080 °C. The image analysis provides both qualitative and quantitative insight of electrode/electrolyte interface. This novel approach of the SOFC

    Full text: Most 19th and early 20th century oil paintings suffer from fading, discolouration, pitting, cracking swelling or the loss of material due to the embrittlement or the extreme friability of the paint layers. As a consequence of this deterioration, they require special care by experienced conservators to ensure their continued preservation. These aging processes are a consequence of (i) chemical interactions between pigments, oils and binders used by the artist and (ii) the action of air, water and ultra-violet irradiation on these materials. The influence of chemical interactions is pertinent for paintings of this era as the industrial revolution brought forth new colourful chemicals that were quickly adopted as pigments with varying success. The conservation of oil paintings requires an understanding of the individual structure of each work of art and what mechanisms underlie its deterioration. This generally involves the need for (i) correct identification of the pigments used by the artist, (ii) a detailed knowledge of the chemical interaction between these pigments, (iii) an understanding of the artist's method of mixing colours and laying paint on the canvas and (iv) a detailed knowledge of the role of the atmosphere, moisture and UV irradiation on painting deterioration. In addition to dealing with the deterioration that occurs within the painting, conservators spend a large portion of their time correcting earlier failed conservation attempts. Most oil paintings from this era are valuable from an artistic or historic perspective and only an extremely small sample may be excised from the work, hence microscopy is an indispensable technique in art preservation. Optical microscopy is the core analysis technique used, however, in recent years a limited number of conservators have begun to use Environmental scanning electron microscopy (ESEM) technology to examine paint layers to take advantage of the accurate and rapid identification of elements present

    Full Text Available The current article has the objective of discussing the limitations imposed on property rights. Using the qualitative research methodology and inductive method, the construction of the text comes from the study of the limiting factors of the use, enjoyment and fruition of the premises, using the contents of the Brazilian Federal Constitution and some of the reflections promoted by Antonio Bartolini, in the lecture Le situazioni giuridiche soggettive nel diritto europeo, as the main theoretical foundation. This research is justified because of the current planet pollution and the scarcity of several natural resources. It attempts to analyze the principle of social function as a restrictive factor, added to the natural and legal - internal and external - limits; modeled on the example of the condominium, the urban plan, the division of urban land and the expropriation, giving particular emphasis to environmental restrictions. As a result, we seek to certify the feasibility of absolute and arbitrary use of the property for a society that moves towards sustainability.

The high probability of non-causal explanations for weak associations revealed by observational studies is emphasized; additionally, the consequences are revealed when weak associations are taken to guide public health interventions, to support diagnosis in occupational medicine and expert reports addressed to the court, and to communicate risks. Shortcomings of risk estimations based only on the evidence from experimental toxicology studies are discussed. Uncertainties involved in extrapolating toxicological findings between species and the relevance of taking into account the dose–response relationships and exposure levels experimented on human populations are also commented upon.

    Sulfate and hydrated sulfate minerals are abundant and ubiquitous on the surface of the Earth and also on other planets and their satellites. The humidity-buffer technique has been applied to study the stability of some of these minerals at 0.1MPa in terms of temperature-relative humidity space on the basis of hydration-dehydration reversal experiments. Updated phase relations in the binary system MgSO"4-H"2O are presented, as an example, to show how reliable thermodynamic data for these minerals could be obtained based on these experimental results and thermodynamic principles. This approach has been applied to sulfate and hydrated sulfate minerals of other metals, including Fe (both ferrous and ferric), Zn, Ni, Co, Cd, and Cu. Metal-sulfate salts play important roles in the cycling of metals and sulfate in terrestrial systems, and the number of phases extends well beyond the simple sulfate salts that have thus far been investigated experimentally. The oxidation of sulfide minerals, particularly pyrite, is a common process that initiates the formation of efflorescent metal-sulfate minerals. Also, the overall abundance of iron-bearing sulfate salts in nature reflects the fact that the weathering of pyrite or pyrrhotite is the ultimate source for many of these phases. Many aspects of their environmental significance are reviewed, particularly in acute effects to aquatic ecosystems related to the dissolution of sulfate salts during rain storms or snow-melt events. Hydrous Mg, Ca, and Fe sulfates were identified on Mars, with wide distribution and very large quantities at many locations, on the basis of spectroscopic observations from orbital remote sensing and surface explorations by rovers. However, many of these findings do not reveal the detailed information on the degree of hydration that is essential for rigorous interpretation of the hydrologic history of Mars.

    Full Text Available The responsibility to preserve the environment can no longer be seen simply as an obligation of the State. It is also the responsibility of the business sector, mainly for being a major cause of environmental degradation, to seek appropriate solutions to internalize the social and environmental costs generated by their production. In recent years there has been a growing adherence of businesses to voluntary instruments of environmental management within the European Union, especially with the adoption of systems such as EMAS and ISO 14000, which combine efforts to regulate even matters that are not included in the current environmental legislation. A responsabilidade de preservar o meio ambiente não pode mais ser encarada como uma obrigação tão somente do Estado, cabe também ao setor empresarial, incluso por ser uma dos maiores causadores da degradação ambiental, buscar soluções adequadas para internalizar o custo sócio-ambiental gerado por sua produção. Nos últimos anos vem crescendo a adesão de empresas aos instrumentos voluntários de gestão ambiental no âmbito da União Européia, principalmente com adoção de sistemas como o EMAS e a ISO 14000, que combinam esforços no sentido regular inclusive questões que não estão normatizadas na legislação ambiental vigente.

    Full Text Available A produção de biodiesel foi incentivada pelo desejo de se obter fontes energéticas de origem diferente do petróleo. Este processo, contudo, gera grandes quantidades de glicerina como subproduto. Assim, novas aplicações devem ser encontradas para esta glicerina evitando o colapso da cadeia nacional produtiva de glicerina animal. Uma aplicação mais nobre para esta glicerina, proveniente da indústria de biodiesel, é a produção de resinas alquídicas. Estas resinas podem ser utilizadas como matrizes de compósitos para recuperação de ambientes aquáticos impactados por acidentes de derrames de petróleo. Outra aplicação para estes materiais é na remoção e limpeza de águas produzidas e águas de refinaria, visando a atender a legislação ambiental. Neste trabalho, nanocompósitos espumados magnetizáveis foram preparados pela inserção de nanopartículas magnetizáveis em uma matriz de resina alquídica, obtida a partir da glicerina oriunda do óleo de mamona. Os materiais produzidos foram caracterizados por FTIR-ATR, DRX e SAXS. Além disso, a força magnética destes materiais foi estudada bem como a capacidade de remoção de petróleo derramado sobre água. Os resultados são animadores, pois demonstram a obtenção de um nanocompósito que possui força magnética relativa superior à da maguemita pura. Além disso, este nanocompósito é capaz de remover massas de petróleo cerca de 300% superiores às massas do material usado. Estes materiais, portanto, consistem em uma potencial ferramenta para a recuperação de ambientes aquáticos impactados por acidentes de derramamento de petróleo.The biodiesel production was encouraged since the entire world is looking for new energy sources.

From 55 wild hosts including six different species (Nasua nasua, Cebus spp., Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla and Dasyprocta aguti, 323 ticks were collected. Amblyomma ovale ticks were found solely on coatis, and Amblyomma nodosum was identified solely on anteaters. No ticks were found on capuchin monkeys. However, Amblyomma cajennense was found on all parasitized host species with the exception of capuchin monkeys. Giant anteaters displayed the highest infestation abundance, with a mean of 53 ticks∕animal. Environmental sampling yielded 166 adult A. cajennense ticks. The tick species found on domestic animals (Rhipicephalus (Boophilus microplus, R. sanguineus, Dermacentor nitens and A. cajennense were those typically found on these hosts in Brazil. The most prevalent tick species, A. cajennense, was found on both wild and domestic animals and was also prevalent in the environment. Thus, this tick species is the primary vector that allows pathogens to bridge wild and domestic animals in the Cerrado.Neste trabalho são descritas as espécies de carrapatos de animais selvagens e domésticos e do ambiente coletados por um ano na EMBRAPA Gado de Corte localizado na área urbana de Campo Grande, Mato Grosso do Sul, Brasil.

    Full Text Available Companies have been witnessing major changes in their environment and environmental models have been developed aiming to improve their strategic planning. The objective of this study was to examine the environmental approach adopted by companies within the Pulp and Paper, Metallurgical and Sugar and Alcohol sectors, in order to evaluate their environmental performances. The analysis was based on a matrix which relates managerial functions with a set of environmental approaches and performance indicators, classifying the company environmental performance as weak, moderate or strong. The managerial functions approached in this model are: Management (General, Legal Affairs, Finance, Human Resources and Purchasing; Product and Process Development; Production and Maintenance; and Marketing. The analyzed indicators include: international insertion; capital origin and location. The pulp and paper and metallurgical companies obtained average scores of 54.5 and 51.56 points, respectively, being classified as having a strong environmental performance. On the other hand, the sugar and alcohol companies obtained average score of 46 points, being classified as moderate in environmental performance. The high level of environmental performance of pulp and paper and metallurgical companies can be attributed to the following factors: larger international insertion, presence of foreign capital in controlling shares, performance in the international market and company location near large population centers. Pulp and paper and mainly sugar and alcohol companies are less efficient in meeting the requirements of the environmental legislation, particularly those related to the conformity of permanent protected areas and legal reserves.As empresas têm presenciado transformações amplas no ambiente em que estão inseridas e, com o intuito de auxiliar no planejamento estratégico das empresas, têm sido desenvolvidos modelos ambientais.

    A reproducible way to transfer a single crystalline sample into a gas environmental cell holder for in situ transmission electron microscopic (TEM) analysis is shown in this study. As in situ holders have only single-tilt capability, it is necessary to prepare the sample precisely along a specific zone axis. This can be achieved by a very accurate focused ion beam lift-out preparation. We show a step-by-step procedure to prepare the sample and transfer it into the gas environmental cell. The sample material is a GaP/Ga(NAsP)/GaP multi-quantum well structure on Si. Scanning TEM observations prove that it is possible to achieve atomic resolution at very high temperatures in a nitrogen environment of 100,000 Pa.

    This work presents the Agenda 21 Local construction process developed by PETROBRAS within the context of the 'De Olho no Ambiente' Program. This is an alternative for the sustainable development of reduced social inclusion communities located in the Company's areas of influence in the Amazon Region. Agenda 21 is a participative process that analyzes a country, state, municipal or community's actual situation, and plans its sustainable future. Its objective is to reach a new development paradigm, through the construction of an action plan focused on a future scenario desired by the local community, which takes into consideration the vulnerability and potential analysis of its socio-economical, cultural and environmental bases. PETROBRAS has introduced Agenda 21 Local in three riverside communities located in the Coari municipal, where the Solimoes Terminal (TESOL) is situated. This terminal receives and stores petroleum and gas from the Urucu Petroliferous Province, in the Amazonian State. In each location partnerships were signed with several governmental and civilian institutions during the implementation of the Agenda 21 Local Forum. Here each participant has the right to debate, which makes this a participative management process mechanism and an act of citizenship. (author)

The objective of this research was to estimate phenotypic, additive genetic and environmental correlations for a number of traits of agronomic interest in carrot (Daucus carota L. cultivar Campinas, grown during the fall-winter and spring-summer seasons at the Experiment Station of Monte Alegre do Sul, Instituto Agronômico de Campinas (IAC, State of São Paulo, Brazil. This germplasm, originated from the "Seção de Hortaliças" (IAC, presents, besides a high level of resistance to Alternaria dauci, a large variation for root shape and a tendency to early bolting, stimulated by low temperatures and/or long photoperiods during the crop vegetative stage. Data were obtained by evaluating 102 half-sib progenies on a randomized block design experiment with four and three replications, respectively, for the fall-winter and spring-summer planting dates. Phenotypic (rF, additive genetic (rA and environmental (rE correlations were estimated by covariance analyses between pairs of characters, in both planting dates. The phenotypic and additive genetic correlations were negative only for pairs of characters involving percentage of early flowering (EF or percentage of defective roots, while the correlations were high (>0.5 for most of the pairs of characters in both planting dates. Selection for percentage of cylindric marketable roots will lead to reduction in EF as well as increases in marketable root yield and total root yield in both planting. This research further presents a discussion of the relative participation of environmental and genetic effects in the phenotypic correlation.

    The Mexican transportation sector, as with that of many other countries, is characterized by basing its energy consumption in hydrocarbons (gasoline, diesel and LP gas). At the present times, this dependency has brought along a series of problems of environmental nature, which concentrate in a larger scale in the urban areas. Therefore, the study of the transportation sector as an energy consumer requires the institution of new terms where the constant to study (directly or indirectly) is the environmental variable, trying to correlate the proper sector activities, its development and the energy consumption with the environment. This paper`s objective is to know the actual situation of the transportation sector in the metropolitan area of Mexico City (MAMC) and its environmental impact. It is therefore an energy-environmental inventory energy-environmental focussed to the use of fuels in the transportation sector, whose environmental effect has a significant cost for the country. This paper has been divided in four parts. First, the importance of the sector as an energy consumer in the MAMC is characterized in aggregated form. Second, the main variables that affect the development of the sector to obtain the consumption in separated form as well as the base criteria for its development, obtaining a series of results that show the effect of the different modes and types of energy consumption. In the third part, reference is made to the environmental impact originated by the utilization of fossil fuels in the transportation sector, emphasizing in the transportation means that more heavily affect for the emission of pollutants. Finally a series of options are presented that allow finding an equilibrium among transportation, energy and environment.

    Full Text Available A educação ambiental crítica e emancipatória exige que os conhecimentos sejam apropriados, construídos, de forma dinâmica, coletiva, cooperativa, contínua, interdisciplinar, democrática e participativa, voltados para a construção de sociedades sustentáveis. Este artigo trata dos temas ambientais como temas geradores para a educação ambiental, inspirados na pedagogia Paulo Freire, para quem educar é um ato de conhecimento da realidade concreta, das situações vividas, um processo de aproximação crítica da própria realidade: compreender, refletir, criticar e agir são as ações pedagógicas pretendidas. Os temas geradores são, portanto, estratégias metodológicas de um processo de conscientização da realidade opressora vivida nas sociedades desiguais; são o ponto de partida para o processo de construção da descoberta, e, por emergir do saber popular, os temas geradores são extraídos da prática de vida dos educandos, substituindo os conteúdos tradicionais e buscados através da pesquisa do universo dos educandos. O caráter político da pedagogia freireana faz-se presente, de forma radical, nos temas geradores, isto é, temas geradores só são geradores de ação-reflexão-ação se forem carregados de conteúdos sociais e políticos com significado concreto para a vida dos educandos. Assim, as propostas educativas ambientais conscientizadoras podem tomar os temas ambientais locais como temas geradores desta ação conscientizadora, desde que estes temas contenham conteúdos socioambientais significativos para os educandos e sejam definidos coletiva e participativamente.The emancipating and critical environmental education demands that knowledge must be adequate, build up in a dynamic, collective, cooperating, continuous, interdisciplinary, democratic and participating way directed to the construction of self-maintaining societies.

    Lack of data regarding environmental matters in relation to the great majority of MSW landfills throughout Spanish territory makes it difficult to consider them suitable for exploitation or territorial expansion required for different activities demanded by society. The environmental risk of a landfill must be minimised with the help of environmental planning tools. One of these tools is based on the environmental diagnosis and characterisation of the areas affected by the solid waste deposit.. Diagnosis by means of quantifiable environmental indexes helped us in our work to determine the priorities for the environmental control of certain Spanish landfills. This diagnosis was used for creating the Observatory on Solid Waste Landfills, organized by ATEGRUS (Spanish Technical Association for Waste Management) in 2003 and presented at ATEGRUS 30th Annual conference on Controlled Landfills.

    Full Text Available Abstract Background The evolutionary success of phytophagous insects could result from their adaptation to different host-plants. Alternatively, the diversification of widespread species might be driven by adaptation along environmental gradients. To disentangle the respective roles of host-plant versus abiotic environmental variables acting on the genome of an oligophagous insect, we performed a genome scan using 83 unlinked AFLP markers on larvae of the large pine weevil collected on two host-plants (pine and spruce in four forestry regions across Europe. Results At this large geographic scale, the global genetic differentiation was low and there was no isolation by distance pattern, suggesting that migration is overwhelming genetic drift in this species. In this context, the widely used frequentist methods to detect outliers (e.g. Dfdist, which assume migration - drift equilibrium are not the most appropriate approach. The implementation of a recently developed Bayesian approach, conceived to detect outliers even in non-equilibrium situations, consistently detected 9 out of 83 loci as outliers. Eight of these were validated as outliers by multiple logistic regressions: six correlated with environmental variables, one with host-plant and one with the interaction between environmental variables and host-plant. Conclusion These results suggest a relatively greater importance of abiotic environmental variables, as opposed to factors linked with the host-plant, in shaping genetic differentiation across the genome in this species. Logistic regression allows the nature of factors involved in locus-specific selection to be precisely identified and represents another step forward in the process of identifying adaptive loci.

    Lead is an heavy metal that has a major impact on human health and his removal from the environment is an important action for its protection. The aim of the present work is to provide a framework of the Italian lead recycling with respect to the economic and environmental aspects of COBAT activities (COBAT is the Mandatory Consortium to collect and recycle the exhaust lead-acid batteries and lead wastes). In order to better understand the context in which COBAT works, some statistical data on the lead production, consumption and end uses in Italy and in the world are provided. An estimate of the energy consumptions and the environmental impact related to Italian lead production was also carried out. [Italian] Il piombo e' uno dei metalli pesanti a maggiore impatto ambientale e sanitario e la sua rimozione dall'ambiente costituisce un'importante azione di protezione e tutela della salute umana. Lo scopo del presente lavoro e' quello di fornire un quadro di riferimento relativo al riciclaggio del piombo in Italia evidenziandone gli aspetti ambientali ed economici in relazione alle attivita' condotte dal COBAT (Consorzio Obbligatorio delle Batterie Esauste e dei rifiuti piombosi). In tal senso, per disporre di una visione piu' completa del contesto in cui si inserisce l'attivita' del Consorzio, vengono forniti alcuni dati di carattere statistico sulla produzione, sul consumo e sugli utilizzi del piombo in Italia e nel mondo e viene effettuata una stima dei consumi energetici e dell'impianto ambientale associati alla produzione di piombo nazionale.

    Full Text Available This work demonstrates that, for the materialization of the fundamental right to environment, it is necessary that the State intervenes in the Economic Order so as to implement environmental policies that redirect both private initiative and consumers to desirable practices. For such an aim, the efficiency of economic instruments is emphasized by means of the Environmental Tributary Law. Through tributes or concession of fiscal benefits it is possible to induce appropriate practices. This research confirms that the environmental tributary policies in Brazil should take the form of fiscal benefits, instruments considered more appropriate to discourage pollution and foment responsible environmental practices.Demonstra que para a concretização do direito fundamental ao meio ambiente é necessário que o Estado intervenha na Ordem Econômica a fim de implementar políticas ambientais que redirecionem a racionalidade da iniciativa privada e consumidores a práticas ambientalmente desejáveis. Para tal finalidade, enfatiza-se a eficiência dos instrumentos econômicos por intermédio dos institutos do Direito Tributário Ambiental. Por meio da instituição de tributos ou pela concessão de benefícios fiscais é possível a indução a práticas ambientalmente adequadas. Constata que a política tributária ambiental no Brasil deve ocorrer por intermédio de benefícios fiscais, instrumentos mais apropriados para desestimular a poluição e fomentar práticas ambientais responsáveis.

    Fish scale has the potential to be a rapid biomarker due to its structure and high possibility to come into contact with any pollutant in the aquatic environment. The scale structure consists of osteoblastic cells and other bone materials such as collagen where it is possible to form a molecular complex with heavy metals such as aluminum and iron. Hence, aluminum and iron in water could possibly destroy the scale material and marked as a scale deformation that quantitatively could be analyzed by comparing it to the normal scale structure. Water sampling and fish cage experiment were performed between June and July 2011 in Porong river which represented the water body that has high aluminum and iron contamination. The filtered water samples were preserved and extracted using the acid-mixture procedure prior to measurement of the aluminum and iron concentrations using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), while samples for total suspended solid (TSS) analysis were kept at 4 °C in cool-boxes. The scales were cleaned with sterile water, then dehydrated in 30, 50, 70, and 90% ethanol and dried on filter papers. They were then mounted on an aluminum stub and coated with gold in a sputter coater prior to Scanning Electron Microscope (SEM) observation. According to the SEM analysis, it was found that there were several deformations on the scale samples taken from sites that have high concentrations of aluminum and iron i.e. the increasing number of pits, deformation and decreasing number of spherules and ridges while the control scale exhibited the normal features. However, the site with higher TSS and pH indicated lower aluminum effect. A moderate correlation was found between the number of pits with aluminum (r=0.43) and iron (r=0.41) concentrations.

Observou-se, por meio do custo ambiental, que a piscicultura convencional causou a deterioração da qualidade da água que foi utilizada. Constatou-se que o sistema de piscicultura utilizando esgoto tratado, sem usar aeração, não causou efeito deletério significante à qualidade da água de reúso (efluente da estação de tratamento de esgoto - ETE. O sistema de piscicultura usando esgoto tratado, com aeração, resultou na melhoria de sua qualidade, quando comparado com o efluente da estação de tratamento, significando que essa prática resultou em um polimento no líquido utilizado. Ambos os sistemas de reúso de águas mostraram-se ambientalmente sustentáveis, o que indica a potencialidade do uso de esgoto doméstico tratado como fonte de água e alimento natural para a piscicultura.This work aimed to evaluate the environmental sustainability of the treated sewage reuse on aquaculture by using the Environmental Sustainability Index of Aquaculture Reuse (ESI AR, Water Quality Index of Aquaculture Reuse (WQI AR and environmental cost (entropy. For conventional aquaculture, a water quality deterioration of the fish tanks was observed by the environmental cost. When treated sewage was used in tanks without external aeration, it was not verified a remarkable water quality deterioration. However, for the tanks externally aerated and fed with treated sewage there was a water quality improvement, in other words a polishing step was taking place. All the systems analyzed showed to be environmentally sustainable, which indicates that the treated sewage can be considered a good water source for aquaculture.

    Based on an arrogant idea that nature would exclusively serve as a source for its own desires, the humanity has always developed an anthropocentric position in its relationship with nature. From the emergence of capitalism and Industrial Revolution, the economy assumes the position of the worst environmental destroyer. However, this conflict between economy and natural environment could not last anymore. Therefore, The appearance of an 'environmental consciousness' on international level had become something inevitable. From this new ecological mentality, countries started to develop a primal environmental legislation, witch culminated, into a process called 'Constitutionalization of environment protection'. In this framework, Brazil produced, in 1988, a Constitution that is considered one of the world's most modern in terms of natural resources protection, turning this subject into a constitutional principle and a fundamental right. This new perspective of environmental defense brought, invariably, many benefits to the maintaining of an ecologically balanced ecosystem. Finally, the world's ecological concept has also changed since industries started to note that environmental policies could generate more profits and turn them more competitive companies. (author)

    Full Text Available The objectives of this work were to caracterize the tropical maize germplasm and to compare the combining abilities of maize grain yield under different levels of environmental stress. A diallel was performed among tropical maize cultivars with wide adaptability, whose hybrid combinations were evaluated in two sowing dates, in two years. The significance of the environmental effect emphasized the environmental contrasts. Based on grain yield, the environments were classified as favorable (8,331 kg ha-1, low stress (6,637 kg ha-1, high stress (5,495 kg ha-1, and intense stress (2,443 kg ha-1. None of the genetic effects were significant in favorable and intense stress environments, indicating that there was low germplasm variability under these conditions. In low and high stresses, the specific combining ability effects (SCA were significant, showing that the nonadditive genetic effects were the most important, and that it is possible to select parent pairs with breeding potential. SCA and grain yield showed significant correlations only between the closer environment pairs like favorable/low stress and high/intense stress. The genetic control of grain yield differed under contrasting stress environments for which maize cultivars with wide adaptability are not adequate.O objetivo deste trabalho foi caracterizar o germoplasma de milho e comparar a capacidade de combinação da produtividade do milho em ambientes com diferentes graus de estresse.

    Full Text Available In ecology and evolution, the primary challenge in understanding the processes that shape biodiversity is to assess the relationship between the phenotypic traits of organisms and the environment. Here we tested for selection on physio-morphological traits measured by scanning flow-cytometry at the individual level in phytoplankton communities under a temporally changing biotic and abiotic environment. Our aim was to study how high-frequency temporal changes in the environment influence biodiversity dynamics in a natural community. We focused on a spring bloom in Lake Zurich (Switzerland, characterized by rapid changes in phytoplankton, water conditions, nutrients and grazing (mainly mediated by herbivore ciliates. We described bloom dynamics in terms of taxonomic and trait-based diversity and found that diversity dynamics of trait-based groups were more pronounced than those of identified phytoplankton taxa. We characterized the linkage between measured phytoplankton traits, abiotic environmental factors and abundance of the main grazers and observed weak but significant correlations between changing abiotic and biotic conditions and measured size-related and fluorescence-related traits. We tested for deviations in observed community-wide distributions of focal traits from random patterns and found evidence for both clustering and even spacing of traits, occurring sporadically over the time series. Patterns were consistent with environmental filtering and phenotypic divergence under herbivore pressure, respectively. Size-related traits showed significant even spacing during the peak of herbivore abundance, suggesting that morphology-related traits were under selection from grazing. Pigment distribution within cells and colonies appeared instead to be associated with acclimation to temperature and water chemistry. We found support for trade-offs among grazing resistance and environmental tolerance traits, as well as for substantial periods of

    Full Text Available O objetivo deste trabalho foi apresentar uma modelagem da distribuição ambiental de vinte e nove poluentes orgânicos encontrados em amostras de lodos de esgoto das estações de tratamento de esgoto de Barueri e Suzano, SP. Lodos de esgoto são misturas de produtos orgânicos e inorgânicos gerados nos processos primários e secundários de tratamento que, mediante adequado controle de qualidade, podem ser reutilizados como fertilizantes agrícolas. O modelo de fugacidade nível I foi aplicado a um sistema compartimental hipotético constituído de ar, água, solo, sedimento, biota aquática e plantas. Foi utilizada a massa molecular, a pressão de vapor, a solubilidade em água, a constante de Henry, o coeficiente de partição octanol-água e a meia-vida no solo de cada um dos poluentes. O coeficiente de sorção no solo, os fatores de bioconcentração em organismos aquáticos, raízes e na seiva do xilema de plantas foram calculados por meio de expressões que correlacionam cada um desses parâmetros com o coeficiente de partição octanol-água do poluente. Foram estimados e usados os coeficientes de partição folha-ar e ar-água e o índice GUS de cada poluente. A modelagem e os cálculos dos fatores de bioconcentração e dos coeficientes de partição revelam os compartimentos preferenciais dos poluentes.The objective of this work was to present a model of environmental distribution of twenty-nine organic contaminants found in samples of sewage sludge of the sewage treatment plant of Barueri and Suzano SP, Brazil.

    The purpose of the present work is to establish a methodology for assessing the sustainability of buildings in Mexico, which can be standardized and comparable with the rest of North America. For this purpose three building assessment systems in North America were first analyzed: (a) Leadership in Energy and Environmental Design (LEED), (b) Living Building Challenge (LBC); and (c) Energy Star for Buildings. In addition, the analysis included Spain's Green Building Council (GBCe), to have a different comparison point with the North American systems. The analysis of the four systems suggests the use of the Energy Star system due to the following reasons: 1) For all systems, the Energy Star system is the basis for comparison in terms of energy consumption and therefore emissions of greenhouse gases, 2) It is the system requiring the simplest description of the building (construction surface, occupancy and energy consumption) and does not require (unlike other systems) data on the location of the buildings, 3) For the LEED, LBC and GBCe systems, the evaluation must be performed by professionals accredited, while for the Energy Star certification is less restrictive A database of public buildings, managed by the Comision Nacional para el Uso Eficiente de la Energia (CONUEE), was used. It integrates a significant number of office buildings occupied by departments and agencies of the federal government in Mexico. This database holds information on annual energy consumption and area occupied. Such database was complemented with available information on Degree Day data provided by the Asociacion de Empresas para el Ahorro de Energia en la Edificacion (AEAEE); it allowed to include information on weather in the same terms as the proposed methodology by Energy Star system. From the analysis, some suggestions are presented below. First, it is suggested to strengthen the collection and integration of information related to commercial buildings in Mexico to implement a

Na tentativa de superar essa condição, propomos a educação estética ambiental como forma de o ser humano relacionar-se com o mundo que habita, tendo o desafio de provocar o reencontro do humano com as dimensões sensível, afetiva e poética que o compõem. Tendo este campo como fundamento, buscamos, teoricamente, refletir sobre a inserção de uma proposta artística como meio de se chegar aos objetivos necessários à educação ambiental. No campo da arte, voltamo-nos ao teatro do oprimido, que tem como principal objetivo a democratização do teatro, considerada atividade orgânica do ser humano. Identificamos nele aproximações com os princípios e objetivos buscados pela educação estética ambiental.The environmental education is aimed at seeking new forms of relationship between human beings and nature. Although based on an ethical position, it carries the difficulties imposed by a plaster model of education, based on the logic of technical-scientific rationality that permeates society. In an attempt to overcome such condition we propose the aesthetic environmental education as a way of human beings to relate with the world they inhabit while posing the challenge to lead the reunion with their sensitive, emotional and poetic dimensions. Having this field as a basis, we, theoretically, reflect on the inclusion of an artistic proposal as a means of achieving the necessary goals for the environmental education. In the field of art, we turn to the theater of the oppressed, which has the goal of theater democratization, as an organic activity of human beings.

Desse último resultado deriva importante conclusão: a de que, uma vez apurados os padrões insatisfatórios de desempenho ambiental, de incubadoras e empresas assistidas, ficariam criadas as condições para a formulação e a implementação de medidas indutoras de novas posturas.The paper aims to contribute to academic reflections on the role of business incubators as institutional agents to promote environmental performance by small firms. Based on the assumption that these firms have natural structural weaknesses and, as a consequence, intrinsic difficulties in investing in environmental assets, the paper suggests that a particular public policy, namely, business incubators, could contribute to overcoming these barriers and thus pave the way for environmental investments. Two important findings should be highlighted: a the neglect of the incubators investigated (and thus, of the nurtured firms with respect to environmental performance; b the absence of stimuli, from business incubators, for environmental investments. From the results, an important conclusion may be drawn: namely, that where weak patterns of environmental

Las imágenes han sido utilizadas como un documento irrefutable de los problemas ambientales y también, como un medio para generar emoción y activar un compromiso en las conductas individuales y colectivas. Las indagaciones que han examinado las representaciones visuales de la naturaleza han privilegiado géneros visuales como la fotografía, el cine y la pintura. En cambio, el humor gráfico - viñetas, comics, historietas- ha sido escasamente analizado. Partimos de la premisa que investigar la relación entre imágenes humorísticas y la cuestión ambiental nos ofrece interesantes elementos para entender el rol que desempeña la cultura visual en la construcción de sentidos y significaciones acerca de la de la naturaleza. Tomamos como corpus de análisis las imágenes humorísticas con contenido ambiental publicadas desde 1996 hasta el año 2010 en una revista de gran circulación en Argentina. Algunos de los interrogantes que articulan esta indagación son los siguientes: ¿Qué temas se introducen desde el humor gráfico como problemas ambientales? ¿Qué relaciones existen entre la agenda ambiental que se configura desde la revista y la que se delinea desde sus secciones de humor? Finalmente nos preguntamos cuáles son las articularidades/potencialidades que este género de imágenes ofrece para pensar la educación ambiental.

    Seriously ill people at high risk of death face difficult decisions, especially concerning the extent of medical intervention. Given the inherent difficulty and complexity of these decisions, the care they receive often does not align with their preferences. Patient decision aids that educate individuals about options and help them construct preferences about life-sustaining care may reduce the mismatch between the care people say they want and the care they receive. The quantity and quality of patient decision aids for those at high risk of death, however, are unknown. This protocol describes an approach for conducting an environmental scan of life-sustaining treatment patient decision aids for seriously ill patients, identified online and through informant analysis. We intend for the outcome to be an inventory of all life-sustaining treatment patient decision aids for seriously ill patients currently available (either publicly or proprietarily) along with information about their content, quality, and known use. We will identify patient decision aids in a three-step approach (1) mining previously published systematic reviews; (2) systematically searching online and in two popular app stores; and (3) undertaking a key informant survey. We will screen and assess the quality of each patient decision aid identified using the latest published draft of the U.S. National Quality Forum National Standards for the Certification of Patient Decision Aids. Additionally, we will evaluate readability via readable.io and content via inductive content analysis. We will also use natural language processing to assess the content of the decision aids. Researchers increasingly recognize the environmental scan as an optimal method for studying real-world interventions, such as patient decision aids. This study will advance our understanding of the availability, quality, and use of decision aids for life-sustaining interventions targeted at seriously ill patients. We also aim to provide

El individualismo metodológico, la preferencia por el uso de encuestas a población general, la falta de un marco teórico fuerte y de atención a factores estructurales e históricos, característicos del trabajo de Dunlap y sus seguidores, parecen ser las principales causas del bloqueo de la sociología ambiental, dada su enorme influencia en la disciplina.

Methodological individualism, the preference for the use of surveys of the general population, the lack of a strong theoretical frame, or of attention to structural and historical factors - all these are faults in the work of Dunlap and his followers. It is these faults that are arguably the main causes of the impasse in which environmental sociology now finds itself.

    In this study, we applied Environmental Scanning Electron Microscopy-Energy Dispersive Spectroscopy (ESEM-EDS) and Atomic Force Microscopy (AFM) analysis to three different cereal caryopses: barley, oat and einkorn wheat. The morphological structures, chemical elemental composition and surface characteristics of the three cereals were described. Regarding the morphology, barley showed the thickest pericarp, providing a strong barrier digestion and absorption of nutrients. The aleurone layer of each cereal type contained protein body globoids within its cells. Large type-A and small type-B starchy granules were revealed in the endosperm of barley and einkorn wheat, whereas irregular starchy granules were found in oats. The starchy granule elemental composition, detected by ESEM-EDS, was rather homogenous in the three cereals, whereas the pericarp and protein body globoids showed heterogeneity. In the protein body globoids, oats showed higher P and K concentrations than barley and einkorn wheat. Regarding the topographic profiles, detected by AFM, einkorn wheat starchy granules showed a surface profile that differed significantly from that of oats and barley, which were quite similar to one another. The present work provides insights into the morphological and chemical makeup of the three grains shedding light on the higher bio-accessibility of einkorn wheat nutrients compared to barley and oats, providing important suggestions for human nutrition and technological standpoints.

    Initial microbial adhesion to surfaces is a complicated process that is affected by a number of factors. An important property of a solution that may influence adhesion is pH. The surface properties of the cedar wood were characterized by the sessile drop technique. Moreover, the interfacial free energy of surface adhesion to the cedar wood was determined under pH values (2, 3, 5, 7, 9 and 11). The results showed that cedar wood examined at different pH levels could be considered hydrophobic ranged from Giwi = -13.1 mJ/m(2) to Giwi = -75 mJ/m(2). We noted that the electron-donor character of cedar wood was important at both basic and limit acidic conditions (pH 11 and pH 3) and it decreased at intermediate pH (pH 5). The cedar wood substratum presents a weak electron acceptor under various pH's. In addition, the adhesion of conidia from Penicilllium expansum to the cedar wood surfaces at different pH values (2, 3, 5, 7, 9 and 11) was investigated using Environmental Scanning Electron Microscopy and image analysis was assessed with the Mathlab(®) program. The data analysis showed that the conidia from P. expansum were strongly influenced by the pH. The maximum adhesion occurs in the pH 11 and pH 3 and decreased to 24% at pH 5.

    Ward closure is a method of controlling hospital-acquired infectious diseases outbreaks and is often coupled with other practices. However, the value and efficacy of ward closures remains uncertain. To understand the current practices and perceptions with respect to ward closure for hospital-acquired infectious disease outbreaks in acute care hospital settings across Canada. A Web-based environmental scan survey was developed by a team of infection prevention and control (IPC) experts and distributed to 235 IPC professionals at acute care sites across Canada. Data were analyzed using a mixed-methods approach of descriptive statistics and thematic analysis. A total of 110 completed responses showed that 70% of sites reported at least 1 outbreak during 2013, 44% of these sites reported the use of ward closure. Ward closure was considered an "appropriate," "sometimes appropriate," or "not appropriate" strategy to control outbreaks by 50%, 45%, and 5% of participants, respectively. System capacity issues and overall risk assessment were main factors influencing the decision to close hospital wards following an outbreak. Results suggest the use of ward closure for containment of hospital-acquired infectious disease outbreaks in Canadian acute care health settings is mixed, with outbreak control methods varying. The successful implementation of ward closure was dependent on overall support for the IPC team within hospital administration.

    Ferromanganese crusts record long-term deep-sea environmental changes. Thus, providing their reliable high-resolution age models is important. We applied a magnetostratigraphic technique to estimate the growth rate of a ferromanganese crust using scanning SQUID (superconducting quantum interference device) microscope (SSM). SSM is designed to map the magnetic field across thin sections with submillimeter resolution. The crust sample was taken from the Takuyo-Daigo Seamount, northwestern Pacific, and recorded a limited supply of dust and sediment from continents. After drift correction and removal of spike noises, the magnetic field values were stacked within the areas of high signal-to-noise ratios. By correlating the obtained profiles with a standard geomagnetic polarity timescale, we obtained an average growth rate of 3.37 ± 0.06 mm/Ma, which is consistent with that obtained by 10Be/9Be geochronology (2.93 ± 0.15 mm/Ma). S ratio mapping shows low values after 3 Ma, associated with voids between columnar structures.

    Full Text Available O pressuposto deste ensaio é o de que, ao longo de sua trajetória, a educação ambiental foi constituindo uma narrativa que lhe é própria. Algumas palavras com sentidos conceituais polissêmicos, como natureza, participação, solidariedade, cooperação, autonomia, interdisciplinaridade e, mais recentemente, sustentabilidade, transdisciplinaridade e transversalidade, fundamentam a Educação Ambiental e fazem parte de seu léxico ou de sua rede semântica. O objetivo é analisar os campos do sentido produzidos por alguns desses termos e a trama de inter-relações entre os sujeitos e suas práticas discursivas, recusando a doutrina da unidade da razão e de um sujeito unitário em direção ao objetivo da perfeita coerência. Como a linguagem forma-se no seio de uma cultura, transita entre o individual/ coletivo, o subjetivo/ cultural, no caso da Educação Ambiental, é carregada de sentidos e de significados de um paradigma emergente, de novos modos de sensibilidades entre utopistas e utopias. É propósito entender se, de fato, a Educação Ambiental, em nome da emancipação, opõe-se ao projeto liberal de uma "razão educadora", de um conhecimento-regulação, de uma educação universal baseada em métodos universais, analisando de modo complexo a função social das narrativas generalistas e/ou denunciatórias. Foi considerado tanto o potencial positivo como os limites analíticos e estratégicos das narrativas que se manifestam de forma auto-referenciais. A preocupação central e conclusiva é: as práticas cotidianas que demandam iniciativas e encaminhamentos podem fazer sentido e criar campos de interface para o exercício de uma Educação Ambiental?The assumption behind this essay is that, throughout its history, environmental education constituted a narrative of its own.

O trabalho utilizou o método de estudo de caso intrínseco e uma pesquisa de toda legislação que afeta o setor, com posterior verificação das mudanças necessárias à legislação e precificação dessas alterações. Em paralelo foi desenvolvido uma pesquisa da disposição a pagar a mais por produtos/serviços ambientalmente corretos, o que resultou em valores percentuais aplicados à fórmula. Como resultado pode-se verificar que diante dos custos auferidos e fazendo-se o cálculo de viabilidade ambiental e financeira, o empresário obtém um retorno sobre o investimento que se justifica, sendo que além do retorno financeiro, ainda evita as sanções pela não adequação à legislação vigente. Conclui-se, portanto, que além da questão ambiental, no caso em estudo, é também financeiramente viável o investimento nas adequações propostas, mesmo sendo esta uma empresa de pequeno porte e familiar.

    Country economic growth is proportional bond to it electric generation increasing capacity. Brazil, which has a power matrix predominantly renewable, currently is increasing generation, from thermoelectricity, due, mainly, to major facilities in relation to environmental licensing. Since this new Thermal Power Plants operating, tied to the generation with those ones already installed, will result in environmental impacts that must be properly controlled. Such control should follow the Environmental Performance Evaluation guidance, standardized by ABNT NBR ISO 14031/04. Therefore, the following work presents the main Environmental Performance Indicators applied to several thermoelectric generation styles (Oil, Natural Gas, Diesel, Mineral Coal, Biomass, Waste, Solar and Nuclear).

À luz de um referencial teórico inserido na tradição dialética emancipatória, problematizamos os limites e as implicações pedagógicas de tais categorias no fazer educativo ambiental. Com isso, sinalizamos para a necessidade de maior reflexão e debates acerca do que representa a incorporação de certos posicionamentos a-históricos e não-dialéticos, apesar de por vezes relacionais, diante dos desafios e finalidades que os educadores ambientais historicamente se colocam. Por fim, reafirmamos a pertinência do método dialético marxiano, quando se tem por objetivo a construção de uma Educação Ambiental baseada na compreensão complexa e contextualizada da realidade e focalizada na superação das relações sociais estabelecidas no capitalismo, como caminho para a concretização de um novo patamar societário na natureza.In this article we establish the critic made to two recurrent categories in Environmental Education, in practical and discursive terms: the fetichism of individuality and the dualism school-society, speech-work. In the context of a theoretical reference from the emancipating dialectic tradition, we question the limits and the pedagogical implications of these categories in practicing environmental education. In this way, we draw attention to the necessity of deeper considerations and more debates of some non-historical and non-dialectic points of view, eventhough sometimes related, in face of the challenges and objectives that environmental educators historically deals with. At last, we reaffirm the relevance of Marx's dialectical method, when the objective is the construction of an Environmental Education established in understanding the reality in its complexity and context, and

In this paper we review the purpose and procedures of environmental impact assessment (EIA, existing regulatory requirements for health effects analysis, and potential barriers to and opportunities for improving integration of human health concerns within the EIA process. We use statutes, regulations, guidelines, court opinions, and empirical research on EIA along with recent case examples of integrated health impact assessment (HIA/EIA at both the state and federal level. We extract lessons and recommendations for integrated HIA/EIA practice from both existing practices as well as case studies. The case studies demonstrate the adequacy, scope, and power of existing statutory requirements for health analysis within EIA. The following support the success of integrated HIA/EIA: a proponent recognizing EIA as an available regulatory strategy for public health; the openness of the agency conducting the EIA; involvement of public health institutions; and complementary objectives among community stakeholders and health practitioners. We recommend greater collaboration among institutions responsible for EIA, public health institutions, and affected stakeholders along with guidance, resources, and training for integrated HIA/EIA practice.A Política Nacional do Meio Ambiente e as leis estaduais relacionadas necessitam que diversas agências públicas analisem e apresentem os potenciais efeitos ambientais mais relevantes das ações da agência, incluindo os efeitos sobre a saúde humana.

    The hydropower plants are responsible for much of the energy generated in the country, there is also a large hydro potential in Brazilian rivers. This form of power generation is considered renewable and fits into the concept of sustainable development, however, social and environmental impacts from the implementation of hydropower projects are known and widely discussed, especially when it comes to large plants. In this context, study the environmental analysis of potential hydropower was incorporated at various stages of the studies implementation, in order to, identify environmental factors and that will restrict or impede construction, to obtain the best option for the environment, evaluate the role and of social and environmental impacts, contribute to improving the design and functionality of the enterprises in order to reduce overall costs, minimize conflicts and assist in preserving the environment. To fulfill these functions to a satisfactory and reliable level, it the study has increasingly used the techniques, tools and applications of Geographic Information Systems in the process of environmental assessment, since they provide procurement, integration, visualization and data analysis of natural resources, its uses and protection, offering greater security and speed in decision making. This paper presents some applications of GIS in environmental assessment processes, developed mainly in the steps of estimating hydropower potential, hydropower inventory, basic design and environmental licensing.

    This study aimed to identify screening tools, technologies and strategies that vision and hearing care specialists recommend to front-line healthcare professionals for the screening of older adults in long-term care homes who have dementia. An environmental scan of healthcare professionals took place via telephone interviews between December 2015 and March 2016. All interviews were audio recorded, transcribed, proofed for accuracy, and their contents thematically analysed by two members of the research team. A convenience sample of 11 professionals from across Canada specialising in the fields of vision and hearing healthcare and technology for older adults with cognitive impairment were included in the study. As part of a larger mixed-methods project, this qualitative study used semistructured interviews and their subsequent content analysis. Following a two-step content analysis of interview data, coded citations were grouped into three main categories: (1) barriers, (2) facilitators and (3) tools and strategies that do or do not work for sensory screening of older adults with dementia. We report on the information offered by participants within each of these themes, along with a summary of tools and strategies that work for screening older adults with dementia. Recommendations from sensory specialists to nurses working in long-term care included the need for improved interprofessional communication and collaboration, as well as flexibility, additional time and strategic use of clinical intuition and ingenuity. These suggestions at times contradicted the realities of service provision or the need for standardised and validated measures. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The present study served to gain further insight into the bactericidal effects of ellagitannins from Acalypha wilkesiana var. macafeana hort. against pathogenic bacteria. Ellagitannins from the aerial parts of A. wilkesiana var. macafeana hort. (EAW) inhibited the growth of Bacillus cereus (ATCC 11778), Bacillus subtilis (ATCC 6633), Staphylococcus aureus (ATCC 11632) and Methicillin-resistant Staphylococcus aureus (MRSA) clinical strain with inhibition zones equal to 11.01 ± 1.53 mm, 16.63 ± 0.11 mm, 11.40 ± 1.10 mm and 8.22 ± 0.19 mm, respectively. The minimal inhibition concentration and the minimal bactericidal concentration of ellagitannins from A. wilkesiana var. macafeana hort. (EAW) against MRSA were 750 µg/mL and 3000 µg/mL, respectively. We then examined the synergistic effect of EAW with three antibiotics, i.e. ampicillin, streptomycin and tetracycline, via the checkerboard assay and time-kill assay and observed that EAW is synergistic with ampicillin against S. aureus (ATCC 11632). Environmental electron scanning microscopy analysis showed cell lysis against S. aureus (ATCC 11632) upon treatment with the ellagitannin fraction. The ellagitannin fraction from A. wilkesiana var. macafeana hort. is bactericidal against gram-positive bacteria tested and works synergistically with ampicillin against S. aureus. Morphology analysis of the cell suggests that the bactericidal property of the ellagitannin fraction mechanism involves lysis of the cell wall. In summary, our studies demonstrate that A. wilkesiana var. macafeana hort. produces bactericidal ellagitannins of clinical and/or cosmetological value. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available Ante el creciente deterioro ambiental y sus posibles consecuencias en la salud de la población resulta una prioridad indiscutible el diseño e instrumentación de políticas que controlen las actividades económicas bajo el criterio de protección a la salud humana y al ambiente mismo. Es preciso que dichas políticas consideren la factibilidad económica de las alternativas de protección existentes. Sin embargo, por la cantidad de intereses dentro del área ambiental, otros factores como el social y el político deben también ser considerados. La evaluación económica ha sido vista como un promisorio fundamento para la toma de decisiones en esta materia. Los autores analizan la capacidad de esta herramienta para organizar en forma sistemática y comparable los costos y los beneficios de alternativas para la solución de problemas ambientales. Se resumen las principales características de los estudios de costo-beneficio y costo-efectividad, las formas de evaluación económica del ambiente, y las particularidades de esta área para la aplicación de dichas técnicas de análisis. Se señalan los límites encontrados en estas herramientas para cuantificar los costos no monetarios de los riesgos ambientales y de los consecuentes daños a la salud, tales como el dolor, el sufrimiento ó la incapacidad de personas económicamente inactivas, constituyendo estos aspectos el reto metodológico de la evaluación económica en el área. Se reflexiona sobre la importancia de ampliar los insumos informativos para la toma de decisiones en materia de salud ambiental en aspectos como la distribución de los costos y los beneficios entre los distintos grupos sociales. Por último se señala tanto la creciente politización del tema ambiental, como la posibilidad técnica de manipulación de estas herramientas de análisis. Partiendo de estos elementos se señala la necesidad, por parte de los evaluadores, de ser conscientes sobre las implicaciones pol

O estudo de caso focaliza uma filial de empresa multinacional localizada no Estado do Rio de Janeiro, que oferece soluções de energia temporária e sistemas de controle de temperatura. Foram selecionados oito funcionários de diferentes setores da empresa para a ponderação das alternativas, de acordo com os diferentes critérios qualitativos. Foi demonstrado que existem conflitos de opinião em relação à priorização das alternativas. Isso ocorreu devido à interdependência das alternativas e porque os diferentes atores visualizam o problema com perspectivas diferentes e têm interesses diversos. Os resultados mostraram que a principal alternativa, segundo a maioria dos atores, é a implementação de um programa de educação ambiental para evitar desperdícios e informar/conscientizar os empregados sobre as questões ambientais.

    The implementation of oil and gas pipeline systems are commonly made in a own or shared with power transmission, rail and crossroads right-of-way. Pipelines are a 'linear' structure, such as power transmission lines, which are established on landscapes with several conformations (accent slopes, swamp and rocky soils), including sites with high environmental sensibility. The services involved on pipeline implementation are very dynamic, involving several number of employees, vehicles, heavy equipment of excavation and welding that results in a high potential to cause environmental and social impacts. This article, based on the Brazilian and foreign experience on pipeline construction, proposes a methodology to prevent and minimize social and environmental impacts during the construction stage of a pipeline system.

    The pre operational monitoring program has been executed in order to set a baseline, on which comparisons with the same points and the same radionuclides will be made after beginning of operation, having the objective of environmental impact evaluation, in the vicinity of the installation. The program was held in the period of 1982 to 1999, collecting non biological environmental samples (aerosol, rain water, surface water, underground water soil and sediment) and samples that are related to the human food chain (manioc, manioc flour, milk, browse, fish, been, corn, cactus and silage). The analyzed radionuclides are natural uranium, natural thorium, Ra-226, Ra-228, Rn-222 and Pb-210. This work intends to analyze data from the last ten years, program (1989 - 1999), analyzing approximately 350 biological samples and 3500 non biological samples, in order to establishing the baseline to be used in future studies of environmental impact.

    The national solid waste policy recommends reducing solid waste generation and reusing them in different applications. Preliminary studies show that the foundry sand generated from cast metal parts undercut, has excellent applicability in grain size stabilization of soils for geotechnical functions, and therefore, should not be discarded as waste. This study aimed at environmental characterization of two lots of waste foundry sand (WFS), from different industries, to the particle size stabilization of a clayey soil for use in coverage of solid waste in landfills. The methodology included physicochemical characterization tests (grain size, permeability, XRF and heavy metals) and environmental (NBR 10004: 2004, NBR 10005: 2004, NBR 10006: 20004 and acute toxicity with Vibrio fischeri). The results prove the environmental viability of using these lots of WFS as functional material in the composition of landfills. (author)

Caffeine is an ingredient in a variety of beverages (coffee, tea, and caffeinated soft drinks and numerous food products (chocolate, pastries, and dairy desserts. Although the human body metabolizes this stimulant efficiently, between 0.5 and 10.0% is excreted, mostly in the urine. Analysis of water samples from the Leopoldina Basin and Guanabara Bay revealed a significant difference between areas not commonly affected by nutrient enrichment or sewage inputs and areas chronically influenced by sewage discharges and elevated eutrophication. Monitoring caffeine will be fundamental in stressed urban aquatic environments where frequent accidental ruptures of sewer lines and discharges of untreated effluents impede effective water quality evaluation with traditional indicators.Este estudo visou avaliar a co-ocorrência de cafeína e a extensão de sua influência frente a outros parâmetros tradicionais de qualidade de água (microbiológicos e físico-químicos, de modo a caracterizá-la como um eficiente indicador de poluição de origem antrópica em ambientes aquáticos urbanos.

    Full Text Available O texto resume as principais questões e conclusões alcançadas na minha tese de doutoramento junto ao Curso de Pós-Graduação em Desenvolvimento, Agricultura e Sociedade - CPDA da UFRRJ. A discussão em torno da interdisciplinaridade ambiental vem crescendo nos últimos anos, tendo sido os anos 1970 e 1980 férteis o suficiente para possibilitar, nos 1990, a construção de uma Educação Ambiental ao nível da especialização profissional. A inserção da temática ambiental no meio acadêmico se fez gradativamente e, embora com muitos obstáculos, tem demonstrado um viés inovador e desafiante de administradores, docentes e discentes tendo em vista a estrutura fragmentada das universidades tradicionais. O exame do estado da arte das Ciências Ambientais possibilitou discernir, para além da compartimentalização e da departamentalização, as principais queixas, dúvidas, caminhos, soluções e espaços que conduziram à elaboração de um campo integrador do fazer científico, reunindo ensino, pesquisa e extensão. O processo de institucionalização exemplificado nos quatro programas brasileiros de pós-graduação estudados permite revelar o quanto se tem progredido no diálogo entre autores/atores das mais diversas origens acadêmicas, promovendo uma interfecundação de grande interesse profissional para os participantes e para o desenvolvimento de uma sociedade sustentável, confirmando até certo ponto a construção de um paradigma para além do reducionismo epistemológico.This article addresses questions that emerged in my research about the matter of cross-disciplinary sciences on environmental issues.

    The Environmental Pre-Communication is a tool developed to identify the profiles of communities surrounding the marked area (lifestyle, resources, fragilities, beliefs, culture and wishes), how they make their living, and production (community dependence relationship with ecosystems, such as rivers and subsistence areas), social organization, needs and expectations. Besides developing a social economic diagnostic, pre-communication prepares a community perception study. Regarding gas pipelines, the area of study comprehends 200 m towards each side of gas pipeline right-of-way in rural areas and 400 m towards each side in urban areas. Pre-Communication diagnostic, which is included in the process of environmental licensing, is aimed at subsidizing EIS (Environmental Impact Statement), providing data which help to elaborate mitigating and compensatory plans and programs. Moreover, diagnostic information make it possible to run public forums before Public Hearings take place, aiming at clarifying specific community issues related to construction and reduction of resistances, avoiding problems and conflicts. Also, during the entrepreneurship implementation phase, there is the advantage to know the bordering community and its daily activities, increasing the effectiveness of Environmental Programs.

    The document describes the outcome of the CSN/CIEMAT-02 interlaboratory test comparison among environmental radioactivity laboratories. The exercise was organised according to the ISO-43 and the ISO/IUPAC/AOAC Harmonized Protocol for the proficiency testing of analytical laboratories. The test sample was a reference materials provided by the IAEA-MEL (IAE Marine Environmental Laboratory, Monaco), a sea fish containing environmental levels of U-238, U-234, K-40, Pb-210, Ra-226, Sr-90, Cs-137, Co-60, Pu-(239+240), Am-241 and Tc-99. The results of the exercise were computed for 32 participating laboratories, and their analytical performance was assessed using the z-score approach. A raised percentage of satisfactory laboratory performance has been obtained for all the analysis, being the best performance in gamma measurements. The laboratories have made an effort to calculate the combined uncertainty of the radiochemical determinations. Most of the laboratories have demonstrated its competence in performing the study analysis and also the adequate measuring capability of their detection equipment even in conditions close to detection limits. The study has shown the capacity of participant laboratories to perform radioactive determinations in environmental sea fish samples with satisfactory quality levels. (Author) 6 refs.

    The multi discipline effects in engineering projects, mainly in those of infrastructure, have extended the borders of research to not only evaluate them of the conventional point of view, economic and technical, but also environmental and social. On the other hand, the investor who traditionally searched alternatives only considering the economic and financial performance currently is taken to analyze also the social and environmental aspects. The model described in this paper is a solution proposal to evaluate the merit of an enterprise of distributed generation of thermal origin, considering the economic, social and environmental aspects, using merit indexes that quantify, directly, economic aspects as capital return tax and operating income eliminates, as well as social factors like the impact in the education, health, income and employment rates and still, it verifies the attendance of the environmental restrictions. The solution presented brings a simple and clear form to attribute a merit degree of aggregate to the alternatives to embed distributed generation, considering the intensity of the subjective social responsibility of the investor. The presented model is an important contribution to stimulate a form to evaluate and to prioritize the multi discipline implementation to a distributed generation enterprise, also being able, to be used as financial index or other incentives of the sort.

    Recent work has highlighted micro-scale roughness on the surfaces of ice crystals grown and imaged in-situ within the chambers of environmental scanning electron microscopes (ESEM). These observations appear to align with theoretical and satellite observations that suggest a prevalence of rough ice in cirrus clouds. However, the atmospheric application of the lab observations are indeterminate because the observations have been based only on crystals grown on substrates and in pure-water vapor environments. In this work, we present details and results from the development of a transfer technique which allows natural and lab-grown ice and snow crystals to be captured, preserved, and transferred into the ESEM for 3D imaging. Ice crystals were gathered from 1) natural snow, 2) a balloon-borne cirrus particle capture device, and 3) lab-grown ice crystals from a diffusion chamber. Ice crystals were captured in a pre-conditioned small-volume (~1 cm3) cryo-containment cell. The cell was then sealed closed and transferred to a specially-designed cryogenic dewer (filled with liquid nitrogen or crushed dry ice) for transport to a new Hitachi Field Emission, Variable Pressure SEM (SU-5000). The cryo-cell was then removed from the dewer and quickly placed onto the pre-conditioned cryo transfer stage attached to the ESEM (Quorum 3010T). Quantitative 3D topographical digital elevation models of ice surfaces are reported from SEM for the first time, including a variety of objective measures of statistical surface roughness. The surfaces of the transported crystals clearly exhibit signatures of mesoscopic roughening that are similar to examples of roughness seen in ESEM-grown crystals. For most transported crystals, the habits and crystal edges are more intricate that those observed for ice grown directly on substrates within the ESEM chamber. Portions of some crystals do appear smooth even at magnification greater than 1000x, a rare observation in our ESEM-grown crystals. The

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

    Full Text Available A multiplicação dos riscos, em especial os ambientais e tecnológicos de graves conseqüências, é elemento chave para se entender as características, os limites e as transformações da nossa modernidade. É cada vez mais notória a complexidade desse processo de transformação de uma sociedade cada vez mais não só ameaçada, mas diretamente afetada por riscos e agravos socioambientais. Os riscos contemporâneos explicitam os limites e as conseqüências das práticas sociais, trazendo consigo um novo elemento, a "reflexividade". A sociedade, produtora de riscos, torna-se crescentemente reflexiva, o que significa dizer que ela se torna um tema e um problema para si própria. O conceito de risco passa a ocupar um papel estratégico para o entendimento das características, dos limites e das transformações do projeto histórico da modernidade e para reorientar estilos de vida coletivos e individuais. Num contexto marcado pela degradação permanente do meio ambiente e do seu ecossistema, isso envolve um conjunto de atores do universo educativo em todos os níveis, potencializando o engajamento dos diversos sistemas de conhecimento e a sua capacitação numa perspectiva interdisciplinar. Os educadores têm um papel estratégico e decisivo na inserção da educação ambiental no cotidiano escolar, qualificando os alunos para um posicionamento crítico face à crise socioambiental, tendo como horizonte a transformação de hábitos e práticas sociais e a formação de uma cidadania ambiental que os mobilize para a questão da sustentabilidade no seu significado mais abrangente.The proliferation of risks, particularly of those of severe environmental and technological consequences, is a key element to understand the features, limitations and transformations of our modernity.

    This chapter reports on the scanning of 1000 holograms taken in HOBC at CERN. Each hologram is triggered by an interaction in the chamber, the primary particles being pions at 340 GeV/c. The aim of the experiment is the study of charm production. The holograms, recorded on 50 mm film with the ''in line'' technique, can be analyzed by shining a parallel expanded laser beam through the film, obtaining immediately above it the real image of the chamber which can then be scanned and measured with a technique half way between emulsions and bubble chambers. The results indicate that holograms can be analyzed as quickly and reliably as in other visual techniques and that to them is open the same order of magnitude of large scale experiments

    Air pollution is one of the leading environmental problems of out times that could eventually change the living conditions of human beings and the ecosystems on the whole planet. Therefore, international forums have been created to discuss environmental policies aimed at the control of pollutant emissions and the protection of ecosystems and human health. the fundamental purpose is to take common actions that go beyond political borders, since in many cases the emissions of pollutants affect ecosystems far from the emission source. These were the objectives leading to the creation of the Geneva Convention on Long-Range Transboundary Air Pollution, of the Economic commission for Europe-United Nations (UNECE). (Author) 12 refs.

  14. Sensitizing Clostridium difficile Spores With Germinants on Skin and Environmental Surfaces Represents a New Strategy for Reducing Spores via Ambient Mechanisms

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Background: Clostridium difficile is a leading cause of healthcare-associated infections worldwide. Prevention of C. difficile transmission is challenging because spores are not killed by alcohol-based hand sanitizers or many commonly used disinfectants. One strategy to control spores is to induce germination, thereby rendering the spores more susceptible to benign disinfection measures and ambient stressors. Methods/Results: C. difficile spores germinated on skin after a single application of cholic acid-class bile salts and co-germinants; for 4 C. difficile strains, recovery of viable spores from skin was reduced by ~0.3 log10CFU to 2 log10CFU after 2 hours and ~1 log10CFU to >2.5 log 10CFU after 24 hours. The addition of taurocholic acid to 70% and 30% ethanol significantly enhanced reduction of viable spores on skin and on surfaces. Desiccation, and to a lesser extent the presence of oxygen, were identified as the stressors responsible for reductions of germinated spores on skin and surfaces. Additionally, germinated spores became susceptible to killing by pH 1.5 hydrochloric acid, suggesting that germinated spores that remain viable on skin and surfaces might be killed by gastric acid after ingestion. Antibiotic-treated mice did not become colonized after exposure to germinated spores, whereas 100% of mice became colonized after exposure to the same quantity of dormant spores. Conclusions: Germination could provide a new approach to reduce C. difficile spores on skin and in the environment and to render surviving spores less capable of causing infection. Our findings suggest that it may be feasible to develop alcohol-based hand sanitizers containing germinants that reduce spores on hands.

    Transgene introgression into crop weedy/wild relatives can provide natural selective advantages, probably causing undesirable environmental impact. The advantages are likely associated with factors such as transgenes, selective pressure, and genetic background of transgene recipients. To explore the role of the environment and background of transgene recipients in affecting the advantages, we estimated the fitness of crop-weed hybrid lineages derived from crosses between marker-free insect-resistant transgenic (Bt/CpTI) rice with five weedy rice populations under varied insect pressure. Multiway anova indicated the significant effect of both transgenes and weedy rice genotypes on the performance of crop-weed hybrid lineages in the high-insect environment. Increased fecundity was detected in most transgene-present F1 and F2 hybrid lineages under high-insect pressure, but varied among crop-weed hybrid lineages with different weedy rice parents. Increased fecundity of transgenic crop-weed hybrid lineages was associated with the environmental insect pressure and genotypes of their weedy rice parents. The findings suggest that the fitness effects of an insect-resistant transgene introgressed into weedy populations are not uniform across different environments and genotypes of the recipient plants that have acquired the transgene. Therefore, these factors should be considered when assessing the environmental impact of transgene flow to weedy or wild rice relatives.

    Full Text Available O objetivo do artigo é discutir a forma como a coincineração de resíduos em fábricas de cimento vem crescendo no Brasil, bem como seus impactos sobre a saúde humana e o meio ambiente. Informações gerais sobre mercado e efeitos sobre a saúde foram obtidas através de revisão bibliográfica e alguns estudos de caso, escolhidos a partir de debate com integrantes da Rede Brasileira de Justiça Ambiental, foram construídos para ilustrar a situação no Brasil. Os estudos encontrados mostraram que, independente do nível de desenvolvimento tecnológico dos países, a saúde dos trabalhadores e das pessoas que moram próximas às fábricas de cimento vem sendo prejudicada pela poluição emitida pelas empresas de cimento, em especial por aquelas que praticam a coincineração. Além disso, no contexto brasileiro, a vulnerabilidade das instituições e populações afetadas tende a agravar este problema. Como conclusão, defende-se o aumento da capacidade institucional dos órgãos brasileiros responsáveis pelo monitoramento das atividades industriais, bem como uma rediscussão mais aprofundada dos aspectos políticos e éticos ligados ao transporte e comércio de resíduos industriais.In this article we discuss the development of hazardous waste co-incineration in cement kilns in Brazil as well as its impacts on health and the environment.

    Full Text Available Studies of soils in Environmental Protection Areas (EPAs are of great importance, because they are an essential component of ecosystems, directly interfering in environmental sustainability. The objective of this study was to evaluate the structural quality of soil cultivated with coffee and used as pasture in the Capituva's River microbasin, which is located in the Environmental Protection Area in Coqueiral, south of the state of Minas Gerais. Uniaxial compression test (preconsolidation test and soil resistance to penetration were used. Undisturbed samples were taken from the surface layer (0-5 cm of the soils in the area: a typic dystrophic Red Latosol (LVd - Oxisol, a typic eutrophic Red Argisol (PVe - Ultisol, and a typic dystrophic Haplic Cambisol (CXbd - Inceptisol. A significant linear positive correlation was observed between the results of the preconsolidation test and soil resistance to penetration. Load bearing capacity of soil could be estimated accordingly by means of penetration resistance for LVd, PVe, and CXbd. Cambisol - CXbd showed lower loading support capacity and resistance to penetration than LVd and PVe, due to the better crop management in this soil that resulted in higher physical quality which accounts for higher production and environmental sustainability.O estudo do solo em áreas de proteção ambiental (APAs é de grande importância, pelo fato deste ser componente essencial dos ecossistemas, interferindo diretamente na sustentabilidade do ambiente.

    Gasoline production in petroleum refineries usually implies carrying high phenol contents in water after treatment systems. Phenols are powerful bactericides and, therefore, harmful to microorganisms present in wastewater treatment plants and in rivers. Due to this reason, usually controlled phenolic water drainage is performed, enabling gasoline quality improvement, without jeopardizing the biological treatment. Increase of phenolic contents in the effluent, due to operational disarray during the drainage of gasoline tanks may cause inhibition or even mortality of the existing microorganisms in the wastewater treatment plants. Aiming at changing the traditional treatment logic of environmental demands at the 'end of pipe', sending the phenolic water to the sour water treatment systems was proposed and implemented, which in turn, is reutilized by the latter in the crude desalination of the Distillation Units, where the phenols are reincorporated to the crude oil, preventing negative consequences to the wastewater treatment plant. The implemented process has demonstrated that premises were correct, enabling to implement process flows quite higher than drainage flows, what has meant productivity gains and environmental improvement.

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

    In order to evaluate the physical value of mineral and water reserves, the concept of Exergy Replacement Cost has been defined as the energy required by the best available technologies to return a resource to the same conditions as it was delivered by the ecosystem. In the case of fossil fuel reserves, a new concept called exergy abatement cost has been proposed as a physical way of measuring the exergy cost of the best available technology for avoiding the environmental externalities associated with the use of fossil fuels. According to the results obtained, the physical value of mineral reserves is 15.4% of oil reserves. In the case of water reserves, 0,4 to 6,4 times the fossil energy consumed would be needed each year to supply only a part of the functions of the hydrological cycle. The global exegetic abatement costs would be 11,3% of the proven world exegetic reserves in fossil fuels. (Author)

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.

    An Environmental Impact Assessment Methodology to assess the impact arising from contaminants present in hazardous and radioactive wastes has been developed. Taking into account of the background information on legislation, waste categories and contaminants inventory, and disposal, recycling and waste treatment options, an Environmental Impact Assessment Methodology (MEIA) is proposed. This is applicable to (i) several types of solid wastes (hazardous, radioactive and mixed wastes; (ii) several management options (recycling and temporal and final storage (in shallow and deep disposal)), (iii) several levels of data availability. Conceptual and mathematical models and software tools needed for the application of the MEIA have been developed. Bearing in mind that this is a complex process, both the models and tools have to be developed following an iterative approaches, involving refinement of the models and go as to better correspond the described system. The selection of suitable parameters for the models is based on information derived from field and laboratory measurements and experiments, nd then applying a data elicitation protocol.. It is shown an application performed for a hypothetical shallow radioactive waste disposal facility (test case), with all the steps of the MEIA applied sequentially. In addition, the methodology is applied to an actual cases of waste management for hazardous wastes from the coal fuel cycle, demonstrating several possibilities for application of the MEIA from a practical perspective. The experience obtained in the development of the work shows that the use of the MEIA for the assessment of management options for hazardous and radioactive wastes gives important advantages, simplifying the execution of the assessment, its tracability and the dissemination of methodology assessment results to to other interested parties.

    of the microeconomic theory in the aspects of the enterprise environmental management is verified thus, mainly for the fact that the environmental question currently influences directly the strategic planning of the organizations.A pesquisa que se segue objetiva apresentar certos fundamentos da microeconomia passíveis de aplicação e análise na gestão ambiental das empresas. Inicialmente realiza-se uma revisão sobre os conceitos e fundamentos microeconômicos, como a curva de possibilidade de produção, custos de poluição e de controle, benefícios e custos totais e marginais e teoria dos jogos; sendo, posteriormente, abordadas suas possíveis influências, inclusive com exercícios hipotéticos para compreensão da aplicabilidade dos fundamentos. Importante salientar que, na abordagem da teoria dos jogos, demonstra-se a justificativa da ação das agências reguladoras como órgãos de implementação de controles ambientais nas empresas. As ferramentas aqui abordadas são consideradas sob o aspecto teórico, mas permitem uma posterior aplicação nos processos gerenciais, na busca por tecnologias produtivas verdes e por certificações específicas. A pesquisa utiliza como metodologia o método dedutivo, buscando da teoria geral da microeconomia uma aplicação específica na gestão ambiental e, como procedimento técnico, utiliza a pesquisa bibliográfica. Verifica-se, assim, a consolidação da aplicabilidade da teoria microeconômica nos aspectos da gestão ambiental empresarial, principalmente pelo fato de que a questão ambiental atualmente influencia diretamente o planejamento estratégico das organizações.

    Full Text Available A longevidade do sobreiro e a capacidade que a cortiça amadia tem de crescer construindo camadas anuais extremamente bem individualizáveis permitiu criar a hipótese de correlação entre as marcas químicas deixadas em cada camada de crescimento e as características ambientais do local onde o sobreiro vegeta. Isto permitiria a construção de séries de novénios de distribuição espacial e temporal da característica que se pretenda estudar. Há nisto algumas semelhanças com abordagens dendrométricas, sendo que estas tendem a ser muito mais agressivas. Foi objectivo deste trabalho que numa fase inicial do estudo se procedesse à criação de uma maneira credível de fazer a quantificação de chumbo (II no felema da cortiça recorrendo a uma técnica de análise química nunca antes utilizada para este efeito – a voltametria. A escolha deste método da análise química moderna resulta do conhecimento das vantagens competitivas que tem sobre outros, quando aquele é aplicável, como se demonstra ser o caso. A metodologia utilizada começou por exigir a recolha de uma porção de cortiça de um sobreiro escolhido ao acaso, de maneira a encontrar o material cortiça como se encontra na árvore. No momento não se consideram possíveis correlações biogeográficas mas tão somente o material propriamente dito. Tendo sido possível fazer a quantificação indicada, estão em curso os estudos necessários à verificação da hipótese que dá o mote a este trabalho de investigação centrado no sobreiro do montado e do sobreiral, sendo que a principal conclusão a retirar é que a possibilidade de utilização do sobreiro como indicador da qualidade ambiental do local, neste caso quanto ao teor em Pb(II, é mais um serviço prestável (pelo ecossistema que orbita em torno do sobreiro às populações humanas da área da bacia mediterrânica ocidental.

    In determining reference levels of environmental radioactivity in ten beaches of Ilha Grande-R J, one used the measurement of gamma dose rates in situ (n Gy h{sup -1}) and the conversion of activity concentration of natural radionuclides {sup 238}Th, {sup 232}U and {sup 40}K (344/Kg) in samples from 0-10 cm sand profile, into gamma dose rate. Besides, the activity concentrations of studied radionuclides in the 10-20 cm and 20-30 cm sand profiles were determined, in order to analyse their process of vertical migration. Among the studied beaches, Preta Beach and Dois Rios Beach were selected to carry out a study of the gamma dose rates variation, during a period of twelve months. The annual absorbed dose rate at 1 m above ground level in the sand area was determined through the measurements of gamma dose rate carried out in situ on the beaches. The mean values of gamma dose rate in situ (n Gy h{sup -1}) in the analysed beaches ranged of 62 +- 7 in Dois Rios Beach to 126 +- 24 in Preta Beach. The primordial radionuclide {sup 40}K was the first contributor for the local gamma dose rate in eight studied beaches. None of studied beaches were considered a radiological risk. Sand features, such as porosity and density contribute to modulate the local environmental radiation levels. The comparison of gamma dose rate values from ten studied beaches, obtained through the two different techniques, showed high similarity between the results (R = 0.85). During the period of study in both analysed beaches, Preta and Dois Rios beaches, there was no variation statistically significant in the terrestrial gamma dose rate measured in situ. The higher annual absorbed dose rates were found in Preta Beach and in Caxadaco Beach, with 0.15 +- 0.03 mSv y{sup -1} and 0.10 +- 0.02 mSv{sup -1} respectively; while in the others beaches the mean value of gamma dose rate was 0.08 mSv y{sup -1}. The values of annual absorbed dose rate shown in this work are below that the values found in some

    Contaminated sites by NAPL (Non-Aqueous Phase-Liquids) may lead to safety risks to human health and to ecosystems, restrictions to urban development and decrease of real estate value. This work used the radon gas as an indicator for the analysis of subsurface soil gas, once this noble gas presents good solubility in a wide range of NAPL, being partially retained in the NAPL contamination. Therefore, a decrease of the activity of radon in the contaminated soil gas can be expected, due to the high capacity of partitioning of radon in NAPL, which allows that the NAPL retain part of the radon previously available in the soil pores. The survey was carried out at a disused industry, contaminated by low volatile NAPL, located at southeast of Sao Paulo city, from June/14 to May/15. Radon was evaluated by passive detection methodology with CR-39 solid state nuclear track detectors (SSNTD) in ten monitoring stations installed in the contaminated area investigated and named 'A' to 'J'. Radon concentrations average for the eight monitoring stations at non-contaminated locations varied from (22 ± 4) kBq.m{sup -3} to (39 ± 4) kBq.m{sup -3} . For the two monitoring stations assumed as contaminated locations, radon concentrations average were (1.4 ± 0.4) kBq.m{sup -3} and (13 ± 9) kBq.m{sup -3}. The results have shown good agreement between the used method and the conventional environmental investigation techniques, for the majority of the monitoring stations in different seasons. Results obtained with CR-39 detectors varied over the exposure time due to the different seasons. No relation was observed between radon activity concentrations and rain volume accumulated over the different CR-39 exposure times. The lowest {sup 222}Rn activity concentrations occurred in 'G' and 'H' monitoring stations, also verifying by gamma-ray spectrometry, that the low activities are not related to the activity concentration of its father {sup 226}Ra from
