  1. el acto impulsivo

    2007-01-01

    Full Text Available Conciencia e impulsividad son dos constructos multidimensionales relacionados con el control del pensamiento y comportamiento humano. Impulsividad es un rasgo de personalidad complejo caracterizado por una elevada tendencia a actuar sin pensar, incapacidad para planear actividades futuras y disminución de la capacidad de concentración. Conciencia por su parte, es un constructo que cobija una serie de procesos fisiológicos relacionados con la generación de experiencia conciente y la adquisición de conocimientos. Con respecto al control sobre la acción humana, conciencia e impulsividad parece estar relacionados con comportamientos opuestos. Históricamente, los esfuerzos realizados por diversas disciplinas con el fin de estudiar estos constructos han llevado al desarrollo de definiciones divergentes y a una serie de medidas, causando una mayor confusión. Los propósitos de este artículo son: 1 describir ejemplos de posibles soluciones al estado de confusión en el campo de la investigación sobre impulsividad y discutir como el estudio de la conciencia puede beneficiarse de la investigación de la impulsividad; 2 discutir algunas de las maneras utilizadas para medir impulsividad en el laboratorio y cómo hacer de estos constructos variables experimentales; 3 resumir algunas de las lecciones derivadas de la comparación de los actos impulsivos con los premeditados desde una perspectiva integral y multidimensional; 4 discutir las implicaciones derivadas del uso de un enfoque multidimensional para el estudio de la conciencia.

    Full Text Available Esta pesquisa se propôs a compreender o significado do abandonopara as crianças institucionalizadas – cinco crianças entre sete e onzeanos de idade, sendo duas do sexo feminino e três do sexo masculino,que se encontram em uma instituição de abrigo da cidade deGoiânia (GO. A psicologia histórico-cultural de Vigotsky, fundamentadano pensamento dialético, norteou esta pesquisa, seguindoos princípios epistemológicos desenvolvidos por GonzalezRey. Os recursos metodológicos utilizados foram: a entrevistasemi-estruturada, a observação participante e a pesquisa documental.Com base na investigação realizada, três categorias de significadosse evidenciaram: a invisibilidade, a transgressão e os vínculosafetivos. Constatou-se na pesquisa que a “voz” das crianças é marcadapela invisibilidade e que raramente alcança os dirigentes dasinstituições. Para tanto, faz-se necessário pensar políticas públicaspara além da perspectiva adultocêntrica, a fim de melhor atender àscrianças.

    2008-01-01

    Full Text Available El derecho internacional ambiental es un conocimiento de carácter transversal, que entre otras consideraciones refleja las preocupaciones de la sociedad por la implementación de un modelo de desarrollo sustentable para el respeto a las reglas del medio natural que garantizan la integridad y renovación de los sistemas naturales. El presente artículo enfoca esta visión a través del análisis de material documental revisado, entre ellos tratados internacionales que permiten distinguir el desarrollo del derecho internacional ambiental y el papel de Organización de las Naciones Unidas (ONU, en el propósito común del derecho individual y colectivo de disfrutar de una vida, un ambiente seguro, sano y ecológicamente equilibrado. En función a estas disertaciones las consideraciones finales exponen parte de la visión que ha estructurado la ONU y que representan un aporte considerable en el fomento de la conciencia mundial sobre la necesidad de establecer vínculos entre las naciones para el continuo desarrollo de esta rama del derecho.

  6. INFLUENCIA DE LOS PROBLEMAS CRÓNICOS DE SALUD EN LAS DIMENSIONES DEL CUESTIONARIO EQ-5D: ESTUDIO EN PERSONAS MAYORES INSTITUCIONALIZADAS Y NO INSTITUCIONALIZADAS

    María Concepción Delgado-Sanz

    2011-01-01

    Full Text Available Fundamento: Las enfermedades crónicas representan factores de riesgo para la calidad de vida relacionada con la salud (CVRS. El objetivo de estudio es analizar la influencia de problemas crónicos de salud autodeclarados en la CVRS, medida a través de las dimensiones del EQ-5D, en personas mayores institucionalizada y no institucionalizada. Métodos: Los datos proceden de dos estudios sobre calidad de vida en personas con 60 o más años de edad, en España, con una muestra de 1.106 personas mayores viviendo en la comunidad, y 234 en centros residenciales. Para analizar la influencia de los problemas crónicos más prevalentes en la CVRS se ajustaron modelos de regresión logística tomando como variable dependiente cada dimensión del EQ-5D y controlando por variables sociodemográficas. Resultados: Los problemas crónicos de salud que influyeron negativamente en la CVRS de los dos grupos de población estudiados, fueron la depresión (rango de OR en las distintas dimensiones del EQ-5D:1,97-6,48, seguida de artrosis/artritis (OR:2,81-6,00, insomnio (OR:2,81-4,61, diabetes (OR:1,68-3,44 e hipertensión arterial (OR:1,42-2,45. Estos problemas afectaron de forma distinta a las dimensiones del EQ-5D y a los dos grupos considerados. Las dimensiones del EQ-5D en las que se observaron más dificultades fueron dolor/malestar y movilidad. Conclusiones: Los resultados de este trabajo indican que el carácter debilitante de las enfermedades crónicas sobre la CVRS es distinto en personas mayores institucionalizadas y no institucionalizadas. Además, destacan la importancia de la promoción de un envejecimiento saludable para atenuar el impacto negativo de los problemas crónicos de la salud sobre la población mayor.

  7. La motivación de los actos administrativos

    OpenAIRE

    López Sotelo, Alberto

    2015-01-01

    La motivación de los actos administrativos es preceptiva legalmente en los supuestos enunciados en el artículo 54.1 de la Ley 30/92 para evitar la arbitrariedad en las decisiones de la Administración Pública que debe servir objetivamente al interés general. Esta Administración es controlada por los tribunales y la falta de motivación en los supuestos en los que se exige es causa de nulidad relativa del acto administrativo en cuestión.

    Full Text Available El presente trabajo presenta algunas reflexiones acerca de la problemática de los jóvenes en conflicto con la ley penal. Se describen cuestiones referentes al acto delictivo en niños y adolescentes, su lugar en lo subjetivo, lo intersubjetivo y el cuerpo social.Se puntualiza la relación entre violencia y vulnerabilidad y cómo  el caso a caso  nos enfrenta  con niños y jóvenes con un alto grado de vulnerabilidad social y desvalimiento anímico.Se considera que algunos de los  actos trasgresores suelen corresponder a estrategias de supervivencia en los que   la violencia surge  como forma de recuperación del sentimiento de sí cuando la experiencia traumática de haber sido víctima de violencia no tuvo posibilidad de ser simbolizada (Slavsky.Se describen las diferentes posiciones psíquicas desde donde se perpetúa un acto trasgresor: desde el  desafío a la ley hasta la desestimación de la misma.Se explicita cómo desde la posición psíquica de estos jóvenes que no se sienten ni nada ni nadie, y para los cuales el otro tampoco es nadie, la no referencia a un tercero posible los coloca en situaciones de anonimato y soledad.Se plantea la pregunta acerca de si es posible pensar la escena jurídica como dispositivo que propicie la responsabilización subjetiva.Se concluye con la aseveración de que no se puede pensar en la responsabilidad subjetiva de los jóvenes denegando la pregunta acerca de la responsabilidad social.

    2009-11-01

    Full Text Available Remontémonos previamente a algunos presupuestos pertinentes al origen y curso de la Didáctica, antes de abordar el tema mismo del acto didáctico. En un principio, había una especie de Arte del discurso, tradicionalmente muy ligado en el Mundo Antiguo con lo que luego sería la filosofía -sobre todo en aquel pensamiento pre-socrático y después socrático- que nunca perdía de vista lo que se iba pensando, había que soltarlo, o enseñarlo, para que en la misma transmisión, en el lenguaje en acto, creciera el pensamiento. La masa misma de este discurso era de transmisión oral y siempre actuaba como Enseñanza, o por lo menos era un discurrir pragmático, naciendo de la calle o las plazas la escuela misma. No debemos, pues, olvidar que la Pedagogía, en sentido amplio, no nace como instrucciones de saberes sabidos acumulados, sino como lenguaje que actúa; es decir, que razona hablando y así va creando el saber. Razón común frente a opinión propia.

Finalmente, proponho a minha própria explicação, baseada no conceito de 'força ductiva'. Mostro que há, mesmo dentro da esfera jurídica, uma variedade de forças ductiva, que vão da simples coerção até conselho e a recomendação. Para terminar, sublinho a centralidade do conceito de "força ductiva" para uma fenomenologia do mundo social.

    Full Text Available O estudo objetivou avaliar o crescimento e desenvolvimento de crianças de 0 a 6 anos institucionalizadas. Abordagem descritiva, transversal e de natureza quantitativa. Foi realizado em um abrigo da Secretaria do Trabalho e Desenvolvimento Social do Governo do Estado do Ceará, nos meses de março e abril de 2011. A amostra foi composta por 44 crianças. Prevaleceram crianças de sexo masculino (59,1%; faixa etária entre 24 a 72 meses (56,8%, e tempo de abrigamento superior a um ano (72,7%. Verificou-se que as crianças estavam na faixa de normalidade nutricional. Porém, 65,9% das crianças não alcançaram pelo menos um dos marcos do desenvolvimento propostos pelo Ministério da Saúde. O estudo possibilitou uma reflexão sobre como as crianças residentes em abrigos estão sendo assistidas pela equipe de saúde, tornando-se necessário realizar o acompanhamento de seu crescimento e desenvolvimento, a fim de intervir sobre as alterações encontradas.

    Full Text Available La viajera espectral de Poema de Chile reflexiona sobre la adopción del nombre Mistral. Los fundamentos de esta elección van desde retornar a una intimidad anterior, la escena primigenia del campo, hasta el rechazo a la sociedad urbana. Este acto moderno de autonominarse constituye una atribución consciente frente al menoscabo y a los insultos recibidos en una posición representativa anterior. En vista de lo cual, la fantasma reclama los lugares, las palabras, los bienes y exige la recomposición de los cuerpos despedazados por el discurso blanco y etnocéntrico.The travelling spectrum of Poema de Chile reflects on the adoption of the name Mistral. The causes of this choice gofrom coming back to a previous intimacy -the original scene of the country- to the rejection of the urban society. The name she gives herself is a conscious act and therefore, a modern one, which is used as a response to the damage she received when she was in a previous situation. As a result, the ghost calls for the places, the language and the goods that were stolen, and she demands to recover the bodies that were torn by the white and ethnocentric discourse.

    Full Text Available Entre la población mayor, uno de los pilares centrales de la calidad de vida es la salud, adquiriendo especial importancia la condición física como capacidad para mantener la independencia funcional. El objetivo general es medir el efecto sobre el equilibrio estático y dinámico, la fuerza y la flexibilidad de ambas extremidades tras un periodo de 3 meses de intervención y posteriormente las consecuencias de otros tres meses sin ejercicios.Metodología: Estudio pre-post intervención en una muestra de 36 ancianos institucionalizados mayores de 65 años con deterioro cognitivo normal-leve, divididos en 3 grupos: ejercicios vestibulares, ejercicios de potenciación y grupo control sin intervención. Resultados: Mejoría significativa del equilibrio, la flexibilidad y la fuerza muscular de miembros inferiores en cada uno de los grupos de intervención con respecto al grupo control. Disminución de la capacidad funcional medida a través de una batería de test tras 3 meses sin intervención. Conclusiones: El equilibrio, la fuerza y la flexibilidad de extremidades inferiores y superiores en personas mayores de 65 años institucionalizadas del presente estudio mejoran con la realización de los protocolos de tratamiento diseñados a partir de ejercicios de potenciación de miembros inferiores y de ejercicios vestibulares, en relación al grupo control. La capacidad funcional va disminuyendo si no se realizan de forma continua ejercicios encaminados a fomentarla

    Full Text Available El presente artículo intenta dar cuenta de la relación entre los actos de habla y la semántica a partir de los criterios utilizados por Austin y Searle en la elaboración desús respectivas taxonomías de actos ilocucionarios. Para esto, se rastrean bibliográficamentealgunos de los conceptos que utiliza Austin en sus conferencias de Harvard de 1955 (Austin, 1996 con la pretensión de intentar desambiguar en parte los criterios utilizados en la elaboración de sus categorías de verbos ilocucionarios. Luego, se revisan algunos conceptos de Searle y su taxonomía de actos ilocucionarios descritos en "Actos de Habla" (Searle, 1994; y desarrollados en "Una taxonomía de los actos ilocucionarios"(Searle, 1991 b. Finalmente, a partir de la revisión de las clasificaciones y la discusión de la idea de significado que sustenta cada autor se obtiene que el significado de los verbos no depende solamente de su constitución léxica dada, sino que además se potencia en la interacción o uso de una expresión en una emisión real, en que se constituye como acto ilocucionario.IThe present article reviews thecriteria used by Austin and Searleon elabora-ting their respective taxonomies of illocutionary acts to account for the way in which speech acts and semantics relate both authors. In addition, some concepts of Searle and his taxonomy described in "Speech Acts" (1994 and developed in "A taxonomyof Illocutionary acts" (1991 are reviewed.Finally, the idea of meaning sustained by each author is discussed.

  6. Clathrin regulates centrosome positioning by promoting acto-myosin cortical tension in C. elegans embryos.

    Spiró, Zoltán; Thyagarajan, Kalyani; De Simone, Alessandro; Träger, Sylvain; Afshar, Katayoun; Gönczy, Pierre

    2014-07-01

    Regulation of centrosome and spindle positioning is crucial for spatial cell division control. The one-cell Caenorhabditis elegans embryo has proven attractive for dissecting the mechanisms underlying centrosome and spindle positioning in a metazoan organism. Previous work revealed that these processes rely on an evolutionarily conserved force generator complex located at the cell cortex. This complex anchors the motor protein dynein, thus allowing cortical pulling forces to be exerted on astral microtubules emanating from microtubule organizing centers (MTOCs). Here, we report that the clathrin heavy chain CHC-1 negatively regulates pulling forces acting on centrosomes during interphase and on spindle poles during mitosis in one-cell C. elegans embryos. We establish a similar role for the cytokinesis/apoptosis/RNA-binding protein CAR-1 and uncover that CAR-1 is needed to maintain proper levels of CHC-1. We demonstrate that CHC-1 is necessary for normal organization of the cortical acto-myosin network and for full cortical tension. Furthermore, we establish that the centrosome positioning phenotype of embryos depleted of CHC-1 is alleviated by stabilizing the acto-myosin network. Conversely, we demonstrate that slight perturbations of the acto-myosin network in otherwise wild-type embryos results in excess centrosome movements resembling those in chc-1(RNAi) embryos. We developed a 2D computational model to simulate cortical rigidity-dependent pulling forces, which recapitulates the experimental data and further demonstrates that excess centrosome movements are produced at medium cortical rigidity values. Overall, our findings lead us to propose that clathrin plays a critical role in centrosome positioning by promoting acto-myosin cortical tension. PMID:24961801

    El conjuro del acto III de La Celestina se inspira en la escena de nigromancia del final del libro VI de la Farsalia de Lucano. El poeta romano se atiene a los procedi mientos del ritual, según vemos por los papiros mágicos griegos y otras fuentes. El pasaje de la Tragicomedia, en cambio, muestra llamativas incongruencias, no por inco mpetencia del autor, sino porque la vieja está muy lejos de ser una poderosa hechicera.

    Full Text Available En este artículo se comparan dos formas de discurso mapuche, representadas por textos religiosos o 'wewpin' y narrativos o 'ngütram'; y se analizan los tipos de actos de habla que mayoritariamente ocurren en ellos, siguiendo la taxonomía de Searle. Se observa que ambos discursos distribuyen selectivamente sus actos, de tal modo que el discurso 'wewpin' utiliza mayoritariamente directivos, mientras que los representativos constituyen la mayoría en los 'ngütram'. Ello debido a las funciones pragmáticas que cada tipo de discurso cumple en la conformación y mantención de la ideología cultural del pueblo mapuche. (In this paper, the author compares two forms of Mapuche discourse, represented by religious texts –'wewpin'– and narrative texts –'ngütram'–. The most recurrent speech acts, according to Searle, are analyzed. The results show that each type of discourse favors a specific type af speech act: wewpin discourse prefers directive acts while ngütram favors representative ones. This is due to the pragmatic function that each type of discourse has in the conformation and preservation of the Mapuche cultural identity.

    2009-12-01

    Full Text Available Background: The prevalence of the metabolic syndrome in diabetics is highest among Hispanic adults. A thiazolidinedione antidiabetic agent found in Actos contributes to its mechanism of action. Actos also decreases insulin resistance in margin of the liver, resulting in increased insulin-dependent glucose disposal and decreased hepatic glucose output. This study primarily focuses on the effects of the secondary treatment of Actos on a group of South Texas Hispanics at risk for Type II diabetes; the participants’ ages ranged from 22 to 86 years. These results were based on their metabolic syndrome health data and the extent of recovery on the basis of their gender. Multiple regression analyses have been conducted to determine the factors affecting the metabolic syndrome data on the gender after secondary treatment. Some auxiliary analyses pertaining to cholesterol levels and weight vs. gender comparisons have been carried out to show the gender disparity.Aims and Objectives: The purpose of this study was to establish the prevalence of the metabolic syndrome in the South Texas region and of individual variables which contributed to obesity of Hispanics at risk for Type II diabetes. Patients with the metabolic syndrome have three or more of these risk factors that include excessive abdominal fat, hypertension, low amounts of HDL cholesterol, elevated triacylglyceride levels, and abnormal blood sugar. They are also three-and-a-half times as likely to die from risks associated with coronary heart disease, as well as an increased risk of liver and kidney disease, and possibly cancer. Non-drug treatment programs for metabolic syndrome such as weight loss, dietary changes, and increased physical activity, decreased the incidence of metabolic syndrome by almost 41 percent, whereas the incidence rate among these patients on drug therapy was reduced by only 17 percent to conclude that there are other options available.Methods and Experimental Design: A

La identificación del problema se realizó durante las estancias realizadas en dos instituciones de salud y emergió la información que se obtuvo de las entrevistas semi-estructuradas, realizadas a diez enfermeras, con un análisis detallado, línea por línea para generar categorías y sugerir la relación entre ellas.Mostrando así resultados sentidos y evidenciado, para mejorar la práctica y el entorno del neonato que está pasando por una situación de cuidado por un proceso de enfermedad, hospitalizado en la unidad de cuidados intensivos neonatales, es importante que el personal de enfermería cuente con el desarrollo de las habilidades de la comunicación no verbal, además de combinar el arte, conocimiento de la tecnología, tratamiento y procedimientos que se realizan al neonato con el enfoque de la individualización y flexibilidad de estos cuidados; ir más allá del cumplimiento de tareas rutinarias, de intuición para tomar decisiones; elaborar estrategias de seguridad y prevención en pro del confort y bienestar. El acto de comunicación con el neonato es un reto para el personal de enfermería que labora en los servicios de la UCIN; mismo que implica el ver, tocar, oír y sentir así como un personal cualificado con elementos de amor y empatía; para poder detectar las necesidades físicas, biológicas y afectivas ya que el neonato manifiesta sus sentimientos y emociones con un lenguaje no verbal. SummaryThe purpose of this model of care is to promote the development of communication skills-infant nurse on staff working in the service of the neonatal intensive care unit, which arises from viewing a problem of nursing practice

    Full Text Available Filiación, o el compartir de un legado de generación a generación, es más evidente al considerar los principios específicos de la arquitectura. Este artículo examina cómo el legado de Le Corbusier fue transmitido a Reiko Hayama, mujer japonesa, pionera en arquitectura, y quien desde 1959 a 1965, forjó su carrera en Tokio trabajando para Kunio Maekawa, uno de los previos colaboradores “del Maestro” de la Rue de Sèvres 35. Posteriormente, decidió mudarse a París y trabajar para Charlotte Perriand y Jean Prouvé, previo a establecer su propio estudio de trabajo en los años 1976 a 2013. Este artículo se centra en las repercusiones del patrimonio de Le Corbusier en la práctica personal de Hayama. Sus reflexiones señalan que Maekawa y Prouvé le dieron paso a un camino que se situaba por fuera de los principios de Le Corbusier, entre los cuales se encuentran: una preocupación ética por el medio ambiente; un proceso en el diseño que deliberadamente tuvo en cuenta un contexto cultural y una forma arquitectónica derivada de un proceso tecnológico de razonamiento. El patrimonio del Modulor fue directamente asumido por Hayama, siendo este una herramienta operativa de suma importancia en la metodología Le Corbusiana.

    The remarkable striation of muscle has fascinated many for centuries. In developing muscle cells, as well as in many adherent, nonmuscle cell types, striated, stress fiberlike structures with sarcomere-periodicity tend to register: Based on several studies, neighboring, parallel fibers at the basal membrane of cultured cells establish registry of their respective periodic sarcomeric architecture, but, to our knowledge, the mechanism has not yet been identified. Here, we propose for cells plated on an elastic substrate or adhered to a neighboring cell, that acto-myosin contractility in striated fibers close to the basal membrane induces substrate strain that gives rise to an elastic interaction between neighboring striated fibers, which in turn favors interfiber registry. Our physical theory predicts a dependence of interfiber registry on externally controllable elastic properties of the substrate. In developing muscle cells, registry of striated fibers (premyofibrils and nascent myofibrils) has been suggested as one major pathway of myofibrillogenesis, where it precedes the fusion of neighboring fibers. This suggests a mechanical basis for the optimal myofibrillogenesis on muscle-mimetic elastic substrates that was recently observed by several groups in cultures of mouse-, human-, and chick-derived muscle cells.

    Full Text Available Computational toxicology combines data from high-throughput test methods, chemical structure analyses and other biological domains (e.g., genes, proteins, cells, tissues with the goals of predicting and understanding the underlying mechanistic causes of chemical toxicity and for predicting toxicity of new chemicals and products. A key feature of such approaches is their reliance on knowledge extracted from large collections of data and data sets in computable formats. The U.S. Environmental Protection Agency (EPA has developed a large data resource called ACToR (Aggregated Computational Toxicology Resource to support these data-intensive efforts. ACToR comprises four main repositories: core ACToR (chemical identifiers and structures, and summary data on hazard, exposure, use, and other domains, ToxRefDB (Toxicity Reference Database, a compilation of detailed in vivo toxicity data from guideline studies, ExpoCastDB (detailed human exposure data from observational studies of selected chemicals, and ToxCastDB (data from high-throughput screening programs, including links to underlying biological information related to genes and pathways. The EPA DSSTox (Distributed Structure-Searchable Toxicity program provides expert-reviewed chemical structures and associated information for these and other high-interest public inventories. Overall, the ACToR system contains information on about 400,000 chemicals from 1100 different sources. The entire system is built using open source tools and is freely available to download.

    Full Text Available RESUMEN: En los últimos años se ha incrementado de forma notable la utilización en las aulas de los programas genéricamente denominados «Enseñar a Pensar». La aplicación de estos programas supone por parte del profesorado la adopción de determinadas metodologías específicas que van más allá de la utilización de algunos recursos instrumentales. Esta metodología viene descrita por Feuerstein (1980 como la «metodología de la mediación», de cuyos elementos fundamentales ofrece una descripción. El propósito de este artículo es hacer un análisis de la metodología de la mediación como actos didácticos interactivos. Para ello utilizamos el planteamiento de Rodríguez Diéguez (1985, que analiza el nivel de concreción curricular del acto didáctico como un proceso generador de textos. La consideración de los actos de mediación como actos didácticos nos permite presentar la intervención cognitiva como un proceso de enseñanza-aprendizaje y tratar estas intervenciones desde un punto de vista pedagógico.ABSTRACT: Over the last years the use of the generically named «teaching to think» programs in the classrooms has increased notably. For the application of these programs teachers need to adopt specific didactic methods and not only instrumental methods. Fuertein (1980 describes these methods as «The method of mediation» of which he describes the most important characteristics. The aim of this paper is to analyze the methodology of mediation as interactive didactic actions. For this proposal we use the Rodriguez Dieguez (1985theory which analyzes the «curricular» concretion level as a process which generates «text». The consideration of mediation acts as a didactic acts enables us to present the cognitive intervention as a «teaching-learning» process and consider the intervention from a pedagogical point of view.

  5. Atmosphere and Ambient Space

    DEFF Research Database (Denmark)

    Schmidt, Ulrik

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

    Full Text Available El análisis del inicio del procedimiento administrativo plantea una serie de interrogantes que no solo deben responder a las implicancias adjetivas que tiene esta etapa procedimental, sino a sus dos modos de plasmación —o, en un sentido más extenso, a su impacto directo sobre diversos términos y actuaciones posteriores que pueden surgir alrededor de la tramitación de este cauce formal—. Los argumentos y las respectivas conclusiones deben tratar de ubicarse más allá de la figura como una mera fase, a fin de presentarla como un acto que abre la puerta a un entramado de relaciones jurídico-administrativas entre dos sujetos de naturaleza distinta y que se encuentran en medio de un camino de diligencias y actuaciones normativamente predeterminadas. Por lo dicho, resulta claro que este acto permite revisar —de manera meridianamente clara— los estatutos conformados alrededor de los intervinientes en un procedimiento, quienes empezarían a desarrollarse con una serie de particularidades con la necesidad de ser resaltadas.

  10. Ambient Dried Aerogels

    2013-01-01

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

  11. Ambient oxygen promotes tumorigenesis.

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

Foram utilizadas a Escala de Desenvolvimento Mental de Griffiths, o Questionário de Comportamentos, as Narrativas sobre o Apego e o Attachment Q-Sort. Os resultados revelaram que o nível de desenvolvimento das crianças foi inferior aos valores normativos. Além disso, os valores apresentados ao nível da psicopatologia, em termos de sintomas de internalização e de externalização, aproximaram-se dos valores clínicos. Não obstante e, em contraste com o esperado, a maioria das crianças apresentou valores próximos da segurança (base segura, os quais não estão associados com a qualidade das narrativas sobre o apego das suas cuidadoras.

Os principais resultados foram: a os irmãos mais velhos demonstraram-se responsivos às solicitações de afeto e cuidado em relação aos irmãos mais novos; foi registrada interação significativa entre as meninas mais velhas com os meninos mais novos; b a brincadeira social mostrou ser uma situação favorável ao estabelecimento das interações afetivas; c a imagem da família aparece representada pela figura materna. Conclui-se que, na falta de um adulto significativo, crianças em situação de abrigo acabam formando relações de apego umas com as outras e que a rede de apoio social representa um importante aspecto na resiliência destas crianças.The present study had as propose to identify the attachment relationships among institutionalized infants. Fourteen infants, living in a shelter, of both sexes, aged between 3 and 9 years old, took part in this study. For the recording of the behaviors, the observational technique known as "focal-subject" was used. The main results permit us to identify: a eldest brothers demonstrate responsive affect and care solicitations to the youngest brothers; it was registered significant interaction among older girls and younger boys; b the play social showed to be a favorable situation for the settlement of the affective interactions; c family image appears represented by the mother figure. Therefore, it is concluded that, when the absence of a significant adult occurs, children living in a shelter situation can development attachment relationships among themselves and that a social support network represents an important aspect in the resilience of these children.

    2014-01-01

    Full Text Available Desde que en 1978 nació la primera niña probeta —Louis Brown—, se cuentan por miles los niños que vienen al mundo por fecundación in vitro. Muchas familias acuden a clínicas de reproducción asistida para tratar su problema de infertilidad y tener un hijo. Los hijos nacidos de este modo son seres humanos dignos. Sus padres los quieren y se entregan a ellos de modo admirable, un comportamiento propio de amor de padres. Ahora bien, ¿justifican éticamente estas bondades cualquier modo de desear un hijo y tenerlo? ¿Es radicalmente un acto de amor humano desear hijos y satisfacer el deseo de tenerlos a través de ese modo artificial? ¿Resulta igual de humano y de digno desearlos eligiendo la fecundación in vitro que desearlos a través de una relación amorosa en la que el hijo surge como fruto de esa donación interpersonal? Resuelvo tales interrogantes de la mano de un sugerente análisis ético elaborado entre otros por Rhonheimer y Carrasco de Paula. En síntesis, sólo la unión sexual íntima y amorosa entre un hombre y una mujer —si es incondicional— puede constituir la causa digna de la existencia de un ser humano. Y tal unión y requisito de incondicionalidad están ausentes en la fivet.

    Full Text Available El presente artículo se inscribe dentro de un proyecto que busca examinar la construcción discursiva de la organización política argentina denominada Juventud Peronista. En el presente trabajo, se analizan tres noticias aparecidas en el diario “La Nación”, correspondientes a un acto encabezado por Cristina Fernández y organizado por distintas corrientes militantes kirchneristas, en conmemoración de la victoria electoral de Héctor Cámpora, el 11 de marzo de 2011. Este acto supuso el afianzamiento de la Juventud Peronista actual en la escena política argentina. El objetivo del trabajo es examinar la forma en que se presenta a los jóvenes militantes kirchneristas a partir de un análisis de la transactividad para observar el rol que se les adjudica como actores sociales. Para la consecución del análisis, se utilizan principalmente las herramientas de la Lingüística Crítica, las cuales se complementarán con la Teoría de la Valoración. El Análisis Crítico del Discurso constituye el marco teórico en el cual se inscribe el proyecto. Concluiremos que si bien los militantes, en general, y los jóvenes, en particular, aparecen mayormente en el rol de agente y no de afectado, se trata de acciones secundarias, en tanto organizadores del acto; acciones que semánticamente connotan pasividad, por ejemplo, pedidos que la Presidenta debe cumplir; o acciones incluidas en el discurso referido de Cristina Fernández.

    Full Text Available Various studies have focused on defining the roles that both doctors and patients should adopt during consultations with a view to improving user satisfaction and confidence in the medical care they receive. These two factors clearly contribute to ensuring compliance with the advice and treatments prescribed by healthcare providers and the subsequent success of consultations. Due to the lack of consensus among researchers, this paper aims to empirically examine how confidence in healthcare varies based on assessments made by users regarding different aspects of medical care. The data were taken from the Survey of primary healthcare users of the Andalusian Healthcare Service in 2006. Trust in healthcare is highly related to the satisfaction users express in the four variables examined in the study. The main conclusion is that successful doctor-patient relationships are based on effective communication and not a mere exchange of information.

    Diferentes estudios se han centrado en definir cuáles son los papeles que deben adoptar médico y paciente durante su relación en la consulta en aras de conseguir altos niveles de satisfacción del usuario y confianza en la asistencia recibida. Elementos ambos de suma importancia para incrementar la probabilidad de seguir los consejos y tratamientos del médico, aspectos indicativos del éxito de dicha consulta. Dada la inexistencia de un consenso claro entre los investigadores, este trabajo se ha centrado en estudiar empíricamente, a partir de los datos de la Encuesta a usuarios de los Servicios de Atención Primaria prestados por el Servicio Andaluz de Salud en 2006, cómo varía la confianza en la asistencia médica en función de las evaluaciones que realizan los usuarios sobre diferentes aspectos del acto médico. Los resultados apuntan que las condiciones de una relación médico-paciente exitosa se basan principalmente en mantener una verdadera comunicación y no un mero

    In this study, the Cloud Condensation Nuclei (CCN) activation properties of the urban aerosol in Vienna, Austria, were investigated in a long term (11 month) field study. Filter samples of the aerosol below 100 nm were taken in parallel to these measurements, and later used to generate "synthetic ambient" aerosols. Activation parameters of this "synthetic ambient" aerosol were also obtained. Hygroscopicity parameters κ [1] were calculated both for the urban and the "synthetic ambient" aerosol and also from the chemical composition. Average κ for the "synthetic ambient" aerosol ranged from 0.20 to 0.30 with an average value of 0.24, while the κ from the chemical composition of this "synthetic ambient" aerosol was significantly higher (average 0.43). The full results of the study are given elsewhere [2,3].

    Full Text Available En el marco de las preocupaciones actuales en torno a la reforma y la modernización administrativa, los valores desde las principales teorías axiológicas - cualidades apriorísticas e independientes de las cosas y los actos humanos – constituyen una perspectiva subjetivista, la cual parte de la idea que es el sujeto quien otorga valor a las cosas. En este sentido, éste no puede ser ajeno a las valoraciones y su existencia sólo es posible en las distintas reacciones que en el sujeto se produzcan. Las cosas por tanto no son valiosas en sí mismas: es el ser humano quien les da su valor; de allí surge la motivación de realizar la presente investigación. El sustento teórico está basado en los contenidos de Muñoz (1998, Frondizi (2001, Marín (1976, Gervilla (2003, entre otros, realizándose bajo un enfoque simbólico interpretativo, a través de una metodología cualitativa de tipo descriptiva y diseño no experimental, mediante un análisis documental. En la gerencia postmoderna se plantea la necesidad de integrar los valores de la convivencia democrática con los valores institucionales. Así, en el marco de una ética de la administración postmoderna, los valores democráticos conforman el eje de ésta última y se convierten en una propuesta orientadora para la consecución del bien común.Palabras Clave: Teorías axiológicas; cualidades apriorísticas; perspectiva subjetivista. The values from the main axiological theories: a priori and independent qualities of things and human actionsAbstractIn the context of current concerns about the reform and administrative modernization, the values from the main axiological theories: a priori and independent qualities of things and human actions, is a subjective perspective, in which part of the idea that is the person who gives value to things.

Sin embargo, el estudio independiente de estos conceptos nos ofrece una oportunidad para profundizar en el proceso mediante el cual los delincuentes pasan al acto en sí. El objetivo de este estudio es sintetizar la evidencia en relación con los precipitadores situacionales del delito, los cuales ofrecen una nueva manera de examinar la interacción entre persona y ambiente en materia de delincuencia. La metodología empleada consiste en una revisión sistemática de la literatura de trabajos empíricos realizados a partir del 2007. Los resultados sugieren que es necesario profundizar en el proceso de toma de decisiones del delincuente desde una perspectiva integrada a nivel teórico, en lugar de hacerlo desde un punto de vista atomizado. Se concluye con una discusión de los resultados, después de considerar las características y limitaciones de los estudios observados.

    Full Text Available El presente estudio, corresponde a un análisis comparativo realizado entre los procedimientos de evaluación de impacto ambiental en Venezuela y en el contexto norteamericano, latinoamericano y europeo. De acuerdo con el estudio realizado el objeto de evaluación que prevalece son las actividades económicas, definidas entre los procedimientos comparados que establecen listas de sujeción. Los criterios más utilizados son el técnicoadministrativo y el ecológico; el primero considera el proyecto, y el segundo los impactos significativos. La técnica de la lista de sujeción la utilizan el 75% de los procedimientos comparados. Cuatro son los términos que más se repiten: ambiente, estudio de impacto ambiental, evaluación de impacto ambiental e impacto ambiental. Pocos procedimientos llegan a una consulta pública avanzada, la mayoría se queda sólo en realizar las consultas necesarias para aprobar o no la acción propuesta. Venezuela se caracteriza por su heterogeneidad, de allí la dificultad de establecer un procedimiento rígido que se ajuste a las exigencias de cada una de las regiones naturales del país. Al formular el procedimiento no hay que olvidar dicha particularidad, además que cada propuesta tiene características propias. Hay que ejecutar y fiscalizar los planes de seguimiento y supervisión, porque constituyen la fuente de información sobre variables e impactos. Finalmente, el decreto 1.257, debe ir más allá de decidir la viabilidad ambiental de la acción propuesta o dejar de ser un acto meramente administrativo.

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

Sin embargo, se desconoce su existencia en forma literal o indirecta, al no ser considerado su aporte, por ejemplo, en los planteos referidos sobre la ciencia y la tecnología de la sustentabilidad. En este trabajo se presentan estos antecedentes, relacionándolos con el objetivo del mismo, que es el de aportar a la dilucidación de la existencia y conformación de la ciencia ambiental. Para esto, se analiza la relación de las disciplinas con la dimensión compleja del ambiente como objeto de estudio y aspectos metodológicos derivados. A los fines de aportar al esclarecimiento conceptual, se identifican las distintas acepciones de ambiente comúnmente referidas en la bibliografía. Además, se discuten aspectos relacionados de multidisciplinariedad, interdisciplinariedad y transdisciplinariedad, y sobre el status epistémico de la ciencia ambiental. Se concluye que una mayor precisión conceptual embasada en un marco compartido por las disciplinas que estudian el ambiente, incluida la ciencia ambiental, y los distintos actores involucrados en las problemáticas ambientales, favorecerá el refinamiento de las metodologías tendientes a disminuir la fragmentación de las investigaciones concernientes y las aplicaciones para su resolución.The existence of an environmental science is recognized in books, journals of science as well as in undergraduate and graduate studies.

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

The compression force and its resulting radius for the ball obey a power law with an exponent that is independent of the thickness and initial size of the sheet.

    Yavari, Arash; Ozakin, Arkadas; Sadik, Souhayl

    2016-07-01

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

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

    Full Text Available El monólogo teatral siempre ha expresado las confesiones íntimas de sus hablantes. Es la función que también adquiere en Diatriba de amor contra un hombre sentado, la única obra teatral de Gabriel García Márquez y uno de los textos del autor colombiano que menor atención crítica ha recibido. El propósito del presente artículo es analizar este monólogo desde la pragmática literaria, entendiendo la diatriba como un acto de habla expresivo determinado por los papeles de sus protagonistas y por los específicos recursos enunciativos, temáticos y retóricos utilizados por el hablante. En el texto que nos ocupa, la diatriba es emitida por una esposa, en el marco de una crisis matrimonial. Como denuncia del machismo de la cultura patriarcal latinoamericana, se puede entender, en consecuencia, como una resemantización feminista de las tradicionales diatribas misóginas.

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

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

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

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

    Full Text Available A evolução dos procedimentos preventivos e curativos em Odontologia, verificados nas duas últimas décadas, levou a uma maior longevidade dos elementos dentários, acarretando com isso, uma maior demanda por tratamento periodontal e, em especial, cárie radicular no paciente idoso. O presente estudo teve como objetivo verificar as condições periodontais e lesões radiculares, de uma amostra de população institucionalizada do município de Piracicaba - SP. Nesse estudo, foram examinados 151 idosos com idade entre 54 e 93 anos. Os sextantes foram examinados e classificados do ponto de vista de saúde periodontal, necessidade de tratamento periodontal, presença de retração gengival e lesões radiculares, utilizando-se como critérios os indicadores da OMS (1999. Comparando-se duas faixas etárias: de pacientes com idade entre 50 e 75 anos e pacientes com idade acima de 75 anos, constatou-se que há um aumento na prevalência de lesões de cárie e outras afecções radiculares, como erosão e abrasão, indicando aumento na susceptibilidade a tais lesões com o passar da idade.Preventive and invasive dental procedures have improved in the last two decades, leading to a greater longevity of teeth. As a result, teeth are more susceptible to periodontal diseases and, consequently, to root caries. The purpose of this study was to verify the prevalence of both periodontal diseases and root caries in an institutionalized population from Piracicaba - SP, Brazil. In this study, 151 subjects, aging 54 to 93 years, were examined. The sample was divided into two groups: a group of subjects aging 50 to 75 years and a group of subjects over 75 years old. The sextants were examined and classified as to periodontal health, periodontal treatment needs, prevalence of gingival recession and root lesions. In conclusion, a high prevalence of root caries was verified. That indicates an increase in the susceptibility to these lesions, which is associated with

Para ello se aborda, en primer lugar, el estudio de algunos aspectos generales de estos procedimientos judiciales; luego se analiza las situaciones jurídicas subjetivas objeto de amparo en cada caso y la actividad administrativa sujeta a este control jurídico; posteriormente, se estudian las diversas pretensiones que se pueden deducir contra la Administración del Estado en este tipo de procedimientos; finalmente, se analizan algunos aspectos concretos del procedimiento dispuesto para el Amparo. Este análisis permite distinguir estos procesos de amparo de los procedimientos ordinarios de control contencioso administrativo, estableciendo sus relaciones y diferencias conceptuales en el Derecho comparadoThis article offers a comparative study of the Chilean recourse about violation of constitutional rights and their equivalents in the Mexican, Argentine and Spanish constitutional systems, with particular reference to the complaints against the administrative decisions. After a general overview of these judicial procedures, the article proceeds to analyze the legal cases for which the recourse is granted, and the types of administrative decisions subject to this control. Next, we study the different kinds of petitions available to complainants. Finally, procedural matters are analyzed in more detail. A distinction is proposed between these constitutional recourses and the ordinary control procedures against administrative decisions, and their relationships, and conceptual differences, are explored in light of Comparative Law

    Full Text Available El objetivo del presente artículo es recuperar las ideas pedagógicas del pensador chileno Valentín Letelier (1852-1919, desde un punto de vista crítico al estado del arte en torno a la noción de acto didáctico. Se examina, en primer lugar, el marco histórico dentro del cual Letelier produce su principal texto pedagógico: Filosofía de la educación (1892. Tomándose como base diversos textos del pensador, se carac-teriza primeramente su discurso pedagógico, desde el punto de vista didáctico, para luego tomar distancia de la arista de la construcción de una pedagogía del desarrollo. En dicho proceso, se focaliza constantemente el ejercicio de resistencia teórica de Letelier –a veces consciente, a veces no– frente a los discursos metropolitanos. Aprovechando ideas de Said (2001 y de Jorge Medina (2006 sobre la resistencia, se explicitan los posicionamientos didácticos visibles de Letelier en sus reinscrip-ciones del discurso europeo, en la reintegraciónde sus fisuras, en sus intervencio-nes e interferencias alegóricas, al mismo tiempo que en sus deudas y tributos con esos discursos metropolitanos. Desde esta perspectiva, el pensamiento de Letelier es considerado una manera de resistencia que permite pensar configuraciones más auténticas del evento didáctico que las existentes en el consenso teórico contempo-ráneo de una didáctica del objeto.

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

    2005-01-01

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

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

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

Realizada pesquisa qualitativa e exploratória em cinco asilos de São Paulo, Brasil. Participaram quarenta idosos de ambos os gêneros, sem distúrbios cognitivos, residentes nas instituições há seis meses ou mais. Foram selecionados vinte sujeitos desnutridos ou em risco de desnutrição e vinte sem risco de desnutrição. Foram utilizadas entrevistas com roteiro semi-estruturado e os dados analisados pela técnica do Discurso do Sujeito Coletivo. Os resultados apontaram que, na percepção dos idosos, a rotina alimentar institucionalizada, os cardápios rotineiros e a oferta insuficiente de hortaliças e frutas interferem negativamente no processo de alimentação. Os idosos reconhecem que a alimentação equilibrada melhora a saúde e a qualidade de vida. Revelam que a inapetência de alguns está relacionada a comidas que não agradam ao paladar, problemas de saúde e à assistência inadequada durante as refeições. Este estudo contribuiu para identificar fatores psicológicos e sociais que podem concorrer para a maior freqüência de desnutrição entre idosos institucionalizados.This study analyzed social representations of institutional eating and nutritional patterns among residents of long-term homes for the elderly, in order to identify conditioning factors for eating behavior that may interfere in their nutritional status.

    2015-10-01

    Full Text Available Ambient systems provide information in the periphery of a user’s attention. Their aim is to present information as unobtrusively as possible to avoid interrupting primary tasks (e.g. writing or reading. In recent years, light has been used to create ambient systems to display information. Examples of ambient light systems range from simple notification systems such as displaying messages or calendar event reminders, to more complex systems such as focusing on conveying information regarding health activity tracking. However, for ambient light systems, there is a broad design space that lacks guidelines on when to make use of light displays and how to design them. In this paper we provide a systematic overview of existing ambient light systems over four identified information classes derived from 72 existing ambient light systems. The most prominent encoding parameters among the surveyed ambient light systems are color, brightness, and their combination. By analyzing existing ambient light systems, we provide a first step towards developing guidelines for designing future ambient light systems.

    2014-09-01

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

A natureza foi compreendida como um complexo de entidades reais, as quais são passíveis de pensamento através da percepção. Essa mesma entidade ao ser representada por uma mente, passa a constituir o que denominamos de ambiente. Este, por sua vez, caracteriza-se não somente pela soma dos meios ambientes das espécies conhecidas, mas por ser uma abstração humana. Ao considerarmos a singularidade de cada espécie e organismo que nesse ambiente se insere, passamos a denominar de meio ambiente os elementos que podem ser percebidos e sobre as quais determinado ser pode atuar. Assim, buscamos elaborar um conceito de meio ambiente mais amplo, que não se restrinja à espécie humana.The concepts of environment, environment and nature in the context of environmental issue: defining meaningsABSTRACTWe present some clarifications that enable us to identify differences between the expressions nature, the environment and environment. This is not an epistemological approach, but rather reflections on these expressions refer and the implications for environmental issues and hence to Science Teaching. The nature was understood as a complex of real entities, which are capable to be thinking through perception. This same entity when is represented by a mind, become what we call the environment. This expression, in turn, is characterized not only by adding the environments species that are known, but to be a human abstraction. When we consider the uniqueness of each species and organism, which in this environment is inserted, we call environment, this is, the elements that can be seen and on which the organism can act

    2014-11-01

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

  10. Ambient Noise Tomography of the British Isles

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

    2009-12-01

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

  20. Ambient Interstellar Pressure and Superbubble Evolution

    CERN Document Server

    Oey, M S

    2004-01-01

    High ambient interstellar pressure is suggested as a possible factor to explain the ubiquitous observed growth-rate discrepancy for supernova-driven superbubbles and stellar wind bubbles. Pressures of P/k ~ 1e5 cm-3 K are plausible for regions with high star formation rates, and these values are intermediate between the estimated Galactic mid-plane pressure and those observed in starburst galaxies. High-pressure components also are commonly seen in Galactic ISM localizations. We demonstrate the sensitivity of shell growth to the ambient pressure, and suggest that superbubbles ultimately might serve as ISM barometers.

  1. CUIDADO AMBIENTAL E RESPONSABILIDADE: POSSÍVEL DIÁLOGO ENTRE PSICOLOGIA AMBIENTAL E LOGOTERAPIA

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

    Parra, J.; George, L. A.

    2009-12-01

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

  6. Revealing source signatures in ambient BTEX concentrations

    International Nuclear Information System (INIS)

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

  1. Broadband Finite Frequency Ambient Noise Tomography

    Science.gov (United States)

    Zhao, K.; Yang, Y.; Luo, Y.; Xie, J.

    2015-12-01

    Ambient noise tomography (ANT) has become a popular method to study the crustal and uppermost mantle structure of the earth in recent years due to its exclusive capability to extract short-period surface wave signals. Most of ANT are based on ray theory that assumes interstation surface waves from ambient noise are mainly sensitive to a narrow zone alone the ray path from one station to the other. Recently, many studies have demonstrated that long-period Rayleigh wave signal with high SNR can be obtained from cross-correlation of ambient noise data and could be used to do long period surface ware tomography. In order to obtain accurate phase velocity maps using long period surface waves from ambient noise, frequency effects must be considered in tomography. In this study, we investigate the feasibility of finite frequency ANT by calculating 2-D phase sensitivity kernel based on Born approximation. In calculating 2D sensitivity kernels for empirical Green's functions extracted from cross-correlations between a pair of stations, one station is regarded as receiver and the other as virtual source. Based on the 2D finite frequency sensitivity kennels, we develop a finite frequency ambient noise tomography method to construct Rayleigh wave phase velocity maps. To demonstrate the feasibility of our developed method, we apply the method to empirical Green's functions extracted from cross-correlations of USArray noise data to construct phase velocity maps at 20-150 sec periods. Our resulting phase velocity maps are very similar to earthquake-based phase velocity maps with almost zero means and 20-30 m/s stand deviations of differences. Major tectonic features in USA are well revealed in our phase velocity maps.

    Full Text Available Cuidado ambiental é termo comum no cotidiano e em atividades como educação ambiental, embora pesquisas psicológicas façam pouco uso do conceito, o que justificou investigar a compreensão popular do termo e analisar suas possíveis relações com indicadores científicos de predisposição pró-ambiental. O questionário aplicado a 355 estudantes universitários da cidade de Natal, RN, de ambos os sexos, continha questões abertas sobre prática pelo respondente de cuidado ambiental e sobre sua disposição pessoal para participar de eventuais campanhas ecológicas futuras, e incluía ainda: Escala de Ecocentrismo e Antropocentrismo, Questionário de Individualismo-Coletivismo, e Inventário Zimbardo de Perspectiva Temporal. As duas formas utilizadas para o relato de cuidado ambiental se mostraram positivamente correlacionados com medidas de ambientalismo econcêntrico, e negativamente com apatia ambiental e individualismo, evidenciando-se como um importante controle metodológico-conceitual quando se busca a "tradução" de resultados de pesquisas psicológicas para o cotidiano das ações de intervenção e educação ambientais

    2002-01-01

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

  9. Thermal explosion in oscillating ambient conditions

    Science.gov (United States)

    Novozhilov, Vasily

    2016-07-01

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

    In this paper, hybrid logic is used to formulate a rational reconstruction of a previously published control flow analysis for the mobile ambients calculus and we further show how a more precise flow-sensitive analysis, that takes the ordering of action sequences into account, can be formulated...... in a natural way. We show that hybrid logic is very well suited to express the semantic structure of the ambient calculus and how features of hybrid logic can be exploited to reduce the "administrative overhead" of the analysis specification and thus simplify it. Finally, we use HyLoTab, a fully automated...... theorem prover for hybrid logic, both as a convenient platform for a prototype implementation as well as to formally prove the correctness of the analysis....

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.

  2. Antimicrobial Applications of Ambient--Air Plasmas

    Science.gov (United States)

    Pavlovich, Matthew John

    The emerging field of plasma biotechology studies the applications of the plasma phase of matter to biological systems. "Ambient-condition" plasmas created at or near room temperature and atmospheric pressure are especially promising for biomedical applications because of their convenience, safety to patients, and compatibility with existing medical technology. Plasmas can be created from many different gases; plasma made from air contains a number of reactive oxygen and nitrogen species, or RONS, involved in various biological processes, including immune activity, signaling, and gene expression. Therefore, ambient-condition air plasma is of particular interest for biological applications. To understand and predict the effects of treating biological systems with ambient-air plasma, it is necessary to characterize and measure the chemical species that these plasmas produce. Understanding both gaseous chemistry and the chemistry in plasma-treated aqueous solution is important because many biological systems exist in aqueous media. Existing literature about ambient-air plasma hypothesizes the critical role of reactive oxygen and nitrogen species; a major aim of this dissertation is to better quantify RONS by produced ambient-air plasma and understand how RONS chemistry changes in response to different plasma processing conditions. Measurements imply that both gaseous and aqueous chemistry are highly sensitive to operating conditions. In particular, chemical species in air treated by plasma exist in either a low-power ozone-dominated mode or a high-power nitrogen oxide-dominated mode, with an unstable transition region at intermediate discharge power and treatment time. Ozone (O3) and nitrogen oxides (NO and NO2, or NOx) are mutually exclusive in this system and that the transition region corresponds to the transition from ozone- to nitrogen oxides-mode. Aqueous chemistry agrees well with to air plasma chemistry, and a similar transition in liquid-phase composition

    2014-07-01

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

    2004-01-01

    This paper intends to identify the modal parameters of an offshore platform under ambient excitation, and to compare the identified results with theoretical solutions. Using ambient sources of excitation to determine the modal characteristics of large civil engineering structures is desirable for several reasons. The forced vibration testing of such structures generally requires a large amount of specialized equipment and makes the tests quite expensive. Also, an automated health monitoring system for a large civil structure will most likely use ambient excitation. The Eigensystem Realization Algorithm (ERA) is applied in conjunctied acceleration information. Finally, offshore platform numerical model gets output response data under ambient excitation. Simulated data from numerical model of an offshore platform under ambient excitation is used for the identification of the system. According to the comparison results, the proposed method is shown to be effective for modal parameter identification under ambient excitation.

  9. The influence of ambient light on the driver

    2008-04-01

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

  10. The Potential for Ambient Plasma Wave Propulsion

    Gilland, James H.; Williams, George J.

    2016-01-01

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

    2016-01-01

    Here we obtain analytical expressions for the frequency response of a cantilever beam in the presence of ambient fluid. The advantage of our approach, besides its simplicity of use, is that it explicitly contains the viscosity and the density of the ambient fluid. Thus, if measuring the frequency spectrum, the expression can be used in the design of viscometers. Conversely, if the ambient fluid is known, the expression can be used in the design of force gauges such as in Atomic Force Microscopy.

    This study examined whether an ambient odor can act as a contextual cue for retrieval of verbal stimuli. Subjects (N = 47) learned a list of 24 words while exposed to one of two odors (either jasmine incense or Lauren perfume) and subsequently relearned the list with either the same or the alternative odor present. Superior memory for the word list was found when the odor present during the relearning session was the same one that had been present at the time of initial learning, thereby demonstrating context-dependent memory. There were no differences in initial learning between the two odor conditions. No differences in pleasantness or intensity were found between the odors. PMID:1594391

    Forthcoming wireless communications will be characterized by the ubiquity of multiaccess. Despite the inherently increased complexity, end-users should be able to take advantage of the most suitable access network. Thus, access selection in an environment with different overlapping radio technologies is of central interest and an architecture is needed that performs equally well on single- and multi-operator scenarios, considers several parameters, and respects the principle of layering. In this paper, we introduce the Ambient Networks heterogeneous access selection architecture explaining how it meets such requirements. We present the essential architectural components and explain their interactions. We illustrate how the proposed architecture works in practice and discuss recent results form our prototype-based validation.

    Full Text Available At present, numerous ambient intelligent (AmI applications are emerging which support current electronic and digitalenvironments. Professionals develop each of them by means of projects. AmI application projects have certain features that make them different from other engineering projects. Moreover, a wide rage of risks are present in the whole project. Therefore, to increase these projects’ chances to be successful, it is necessary to manage their specific risks adequately. In order to support the work of those practitioners managing these threats, this research proposes a multicriteria decision-making methodology called Analytic Hierarchy Process. This technique will enable theprioritization of risks in AmI projects according to their level of threat.

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

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

    In this work, Li/air batteries based on nonaqueous electrolytes were investigated in ambient conditions (with an oxygen partial pressure of 0.21 atm and relative humidity of {proportional_to}20%). A heat-sealable polymer membrane was used as both an oxygen-diffusion membrane and as a moisture barrier for Li/air batteries. The membrane also can minimize the evaporation of the electrolyte from the batteries. Li/air batteries with this membrane can operate in ambient conditions for more than one month with a specific energy of 362 Wh kg{sup -1}, based on the total weight of the battery including its packaging. Among various carbon sources used in this work, Li/air batteries using Ketjenblack (KB) carbon-based air electrodes exhibited the highest specific energy. However, KB-based air electrodes expanded significantly and absorbed much more electrolyte than electrodes made from other carbon sources. The weight distribution of a typical Li/air battery using the KB-based air electrode was dominated by the electrolyte ({proportional_to}70%). Lithium metal anodes and KB-carbon account for only 5.12% and 5.78% of the battery weight, respectively. We also found that only {proportional_to}20% of the mesopore volume of the air electrode was occupied by reaction products after discharge. To further improve the specific energy of the Li/air batteries, the microstructure of the carbon electrode needs to be further improved to absorb much less electrolyte while still holding significant amounts of reaction products.

    Three methodologies have been used to assess the effectiveness of the existing ambient air monitoring system in place at the Savannah River Site in Aiken, SC. Effectiveness was measured using two metrics that have been utilized in previous quantification of air-monitoring network performance; frequency of detection (a measurement of how frequently a minimum number of samplers within the network detect an event), and network intensity (a measurement of how consistent each sampler within the network is at detecting events). In addition to determining the effectiveness of the current system, the objective of performing this assessment was to determine what, if any, changes could make the system more effective. Methodologies included 1) the Waite method of determining sampler distribution, 2) the CAP88- PC annual dose model, and 3) a puff/plume transport model used to predict air concentrations at sampler locations. Data collected from air samplers at SRS in 2015 compared with predicted data resulting from the methodologies determined that the frequency of detection for the current system is 79.2% with sampler efficiencies ranging from 5% to 45%, and a mean network intensity of 21.5%. One of the air monitoring stations had an efficiency of less than 10%, and detected releases during just one sampling period of the entire year, adding little to the overall network intensity. By moving or removing this sampler, the mean network intensity increased to about 23%. Further work in increasing the network intensity and simulating accident scenarios to further test the ambient air system at SRS is planned

    @@ From discussion of the structure of liquid water, we deduce that water under ambient condition is mainly composed of ice Ih-like molecular clusters and clathrate-like molecular clusters. The water molecular clusters remain in a state of chemical equilibrium (reversible clustering reactions). This structural model can be demonstrated by quantitative study on anomalous density with increasing temperature at ambient pressure.

    Full Text Available An investigation was carried out to determine dynamic characteristic of reinforced concrete (RC bridges by using ambient vibration test (AVT. The ambient vibration sources on bridges may come from traffic, wind, wave motion and seismic events. AVT describes the dynamic characteristics of the bridge and ground by measuring the natural frequencies using highly sensitive seismometer sensor. This test is beneficial due to light weight equipment and smaller number of operator required, cheap and easy to be handled. It is able to give a true picture of the bridge dynamic behavior without any artificial force excitation when vibration data is recorded. A three-span reinforced concrete bridge located in Sri Medan, Batu Pahat, Johor was measured by using microtremor equipment consist of three units of 1 Hz eigenfrequency passive sensors used in this test was performed in normal operating condition without excitation required from any active sources or short period noise perturbations. Ten measurements were conducted on the bridge deck and ten measurements on the ground surface in order to identify the natural frequencies of the bridge. Several peak frequencies were identified from three components of Fourier Amplitude Spectra (FAS in transverse (North-South, longitudinal (East-West and vertical (Up-Down direction as well as squared average Horizontal to Vertical Spectral Ratio (HVSR of ground response, computed by using Geopsy software. From the result, it was expected the bridge have five vibration modes frequencies in the range of 1.0 Hz and 7.0 Hz with the first two modes in the transverse and longitudinal direction having a frequency 1.0 Hz, the third mode is 2.2 Hz in transverse direction, fourth and fifth mode is 5.8 Hz and 7.0 Hz. For ground natural frequencies are in range 1.0 Hz to 1.3 Hz for North-South direction and 1.0 Hz to 1.6 Hz for East-West direction. Finally the results are compared with several empirical formulas for simple

    Full Text Available This article was written as a result of a master research project (Rico, 2009, and it tackles the problem of the act from a wide metapsychological revision of Freud’s work. The author first analyses the bipartite model of psychic functioning found in “The Interpretation of dreams” (Freud, 1900. The text gathers together several arguments to justify a third dimension of psychic mediation operated by the motor derivation and, despite its indirect associative process exclusion, it is difficult to understand it from the elementary logic in which we find the direct psychic mediation. // En este artículo, que está inspirado en una investigación de maestría (Rico, 2009, se aborda el problema del acto a partir de una amplia revisión metapsicológica por la obra freudiana.

En el devenir del texto se reúnen argumentos para justificar una tercera modalidad de mediación psíquica que opera la derivación motora y que, aunque excluye el proceso asociativo indirecto, es difícil concebirla a partir de la lógica elemental en que se presenta la mediación psíquica directa.

  4. Effect of ambient-pressure reduction on multibubble sonochemiluminescence

    The effect of ambient-pressure reduction on multibubble sonochemiluminescence (MBSCL) is studied experimentally with a luminol solution through measurements of MBSCL intensity as a function of ultrasound irradiation time, applied voltage to a transducer and ultrasonic frequencies to accomplish high efficiency in chemical reactions. From the measurement of ambient-pressure dependence, it is shown that there is an ambient pressure that produces the maximum intensity of the MBSCL and the maximum intensity appears at higher ambient pressure as the applied voltage to the transducer increases. The highest intensity of MBSCL is obtained by appropriate reduction of ambient pressure both for various applied voltages and frequencies. This is caused by both the number of bubbles induced with supersaturation of the gas in a luminol solution and the variation in bubble dynamics.

    Ambient noise is very important in the prediction system of a sonar performance, because it determines the detection ranges always in a passive sonar and usually in an active sonar. In the uncertainty issue for the so-nar performance, it is necessary to know this factor’s statistical characteristics that are only obtained by data processing from the underwater ambient noise measurements. Broad-band ambient noise signals from 16 hydrophones were amplified and recorded for 2 min every 1 h. The results show that the ambient noise is essentially depth independent. The cross correlation of the ambient noise levels (1, 6 and 12 h average) with a wind speed is presented. It was found that the correlation is excellent on the upper frequency band and the noise levels correlate better with high wind speed than with low wind speed.

    To characterize the island-wide background seismic noise in Taiwan, we estimate the power spectral density (PSD) at broadband stations of both the BATS (Broadband Array in Taiwan for Seismology) and the TAIGER experiment (Apr. 2006~Apr. 2008) for periods ranging from ~0.2 to 100 seconds. A new approach to calculate the probability density functions of noise power (PDFs, MaNamara and Buland, 2004) is used in this study. The results indicate that the cultural noise at higher frequencies is significant at populated area, which shows diurnal and weekly variation as what we expected. The noise power for microseisms centered at a period of ~5 seconds around the western costal plain show ~20dB higher than what observed at eastern Taiwan. This observation supports the inference that the coastal regions having narrow shelf with irregular coastlines are know to be especially efficient at radiating the predominat microseisms. Results from the linear array across central Taiwan demonstrate that the average noise power is quietest at the eastern Central Range. We have mapped the PDF mode for stations at various periods to see the spatial distribution of ambient noise levels, which could be used as the basic information for future station siting. Temporal variation of noise PSD is also present to provide a quantitative description of the seismic data quality collected by both BATS and TAIGER experiment. Some operational problems like base tilt, sensitivity change can be identified easily as well.

  10. Control of flowering by ambient temperature.

    2015-01-01

    The timing of flowering is a crucial decision in the life cycle of plants since favourable conditions are needed to maximize reproductive success and, hence, the survival of the species. It is therefore not surprising that plants constantly monitor endogenous and environmental signals, such as day length (photoperiod) and temperature, to adjust the timing of the floral transition. Temperature in particular has been shown to have a tremendous effect on the timing of flowering: the effect of prolonged periods of cold, called the vernalization response, has been extensively studied and the underlying epigenetic mechanisms are reasonably well understood in Arabidopsis thaliana. In contrast, the effect of moderate changes in ambient growth temperature on the progression of flowering, the thermosensory pathway, is only starting to be understood on the molecular level. Several genes and molecular mechanisms underlying the thermosensory pathway have already been identified and characterized in detail. At a time when global temperature is rising due to climate change, this knowledge will be pivotal to ensure crop production in the future. PMID:25326628

    International Nuclear Information System (INIS)

    The purpose of this Analysis/Model Report (AMR) is to evaluate (by means of 2-D semianalytical and 3-D numerical models) the transport of radioactive solutes and colloids in the unsaturated zone (UZ) under ambient conditions from the potential repository horizon to the water table at Yucca Mountain (YM), Nevada. This is in accordance with the ''AMR Development Plan U0060, Radionuclide Transport Models Under Ambient Conditions'' (CRWMS M and O 1999a). This AMR supports the UZ Flow and Transport Process Model Report (PMR). This AMR documents the UZ Radionuclide Transport Model (RTM). This model considers: the transport of radionuclides through fractured tuffs; the effects of changes in the intensity and configuration of fracturing from hydrogeologic unit to unit; colloid transport; physical and retardation processes and the effects of perched water. In this AMR they document the capabilities of the UZ RTM, which can describe flow (saturated and/or unsaturated) and transport, and accounts for (a) advection, (b) molecular diffusion, (c) hydrodynamic dispersion (with full 3-D tensorial representation), (d) kinetic or equilibrium physical and/or chemical sorption (linear, Langmuir, Freundlich or combined), (e) first-order linear chemical reaction, (f) radioactive decay and tracking of daughters, (g) colloid filtration (equilibrium, kinetic or combined), and (h) colloid-assisted solute transport. Simulations of transport of radioactive solutes and colloids (incorporating the processes described above) from the repository horizon to the water table are performed to support model development and support studies for Performance Assessment (PA). The input files for these simulations include transport parameters obtained from other AMRs (i.e., CRWMS M and O 1999d, e, f, g, h; 2000a, b, c, d). When not available, the parameter values used are obtained from the literature. The results of the simulations are used to evaluate the transport of radioactive solutes and colloids, and

    The specific technical challenges associated with the design of an ambient energy powered electronic system currently requires thorough knowledge of the environment of deployment, energy harvester characteristics and power path management. In this work, a novel flexible model for ambient energy harvesters is presented that allows decoupling of the harvester's physical principles and electrical behavior using a three dimensional function. The model can be adapted to all existing harvesters, resulting in a design methodology for generic ambient energy powered systems using the presented model. Concrete examples are included to demonstrate the versatility of the presented design in the development of electronic appliances on system level.

    Ambient air pollution is a known public health hazard that negatively impacts non-cutaneous organs; however, our knowledge regarding the effects on skin remains limited. Current scientific evidence suggests there are four mechanisms by which ambient air pollutants cause adverse effects on skin health: (i) generation of free radicals, (ii) induction of inflammatory cascade and subsequent impairment of skin barrier, (iii) activation of the aryl hydrocarbon receptor (AhR) and (iv) alterations to skin microflora. In this review, we provide a comprehensive overview on ambient air pollutants and their relevant sources, and highlight current evidence of the effects on skin. PMID:26289769

    We investigate the ambient noise cross-correlations obtained by using properly corrected accelerometric recordings, and determine velocity structure in central Mexico based on a dispersion analysis. The data used comprise ten months of continuous recordings - from April 2013 to January 2014 - of ambient seismic noise at stations operated by the National Seismological Service of Mexico and the Engineering Strong Ground Motion Network of the National Autonomous University of Mexico (UNAM). The vertical component of ambient noise was base-line corrected, filtered, and properly integrated before extracting Green's functions (GF), which were compared successfully against GF obtained using recordings from broadband velocity sensors. In order to obtain dispersion curves, we estimated group and phase velocities applying the FTAN analysis technique and obtained s-wave velocity profiles at selected regions. We conclude and highlight that the use of widely deployed accelerographs to conduct regional studies using ambient noise tomography is feasible

    Full Text Available A liquid bridge is a liquid column held captive between two coaxial and parallel solid disks. It is an excellent test bench where measuring the surface tension. In this paper, we used this fluid configuration to examine experimentally the effects of ambient impurities on the surface tension over time. For this purpose, the liquid bridge equilibrium shape was analyzed when the liquid bridge was surrounded by three environments: the uncontrolled ambient, and both air and argon encapsulated in a small glass cover. Ambient contamination produced a sharp decrease of the surface tension of ultra-pure water. The presence of an anionic surfactant in the free surface of an aqueous solution did not inhibit the action of impurities coming from the ambient. Impurities can influence the dynamical behavior of the free surface in flows dominated by the surface tension. Therefore, a careful control of that influence can be crucial in many applications of fluid mechanics.

Desde la perspectiva socio ambiental podemos observar algunos cambios jurídico – institucional, que se han dado desde el proceso de reforma de la Constitución 2008, cuyo mayor logro ha sido la incorporación de los derechos de la Naturaleza como sujeto de de derecho, situación que pone al país a la vanguardia de reconocer aquellos derechos fundamentales para la vida, pero que irónicamente a nivel de todo el planeta los gobiernos no le dan la debida importancia. Así mismo el texto explica la conflictividad existente en la región sur del Ecuador específicamente en la Provincia de Morona Santiago, sus actores, el proceso y dinámica del conflicto, la identificación de los Actores involucrados, un detenido análisis de posiciones, intereses y necesidades de actores centrales, las estrategias y métodos aplicados por los actores, los resultados de las acciones de cada actor, el papel del Estado y/o autoridades competentes y las acciones emprendidas y balance de la Intervención. De la misma forma se realiza un análisis de nuevos cuerpos legales orientados a recuperar el rol planificador del estado y así mejorar la gestión sobre el manejo del territorio, los recursos naturales y la inversión social, impulsando además un proceso de desconcentración y descentralización. Sin embargo pese a tener un nuevo marco legal bajo un ideal que se orienta a lograr un equilibrio entre el ser humano y la naturaleza (régimen del Buen Vivir o Sumak Kausay, aún estamos lejos de lograrlo, pues en la práctica muchas políticas y acciones se contradicen con los enunciados de la nueva Constitución, por lo tanto ahí reside el gran

Para ello, en primer lugar, identificaremos conceptualmente el escenario y el proceso de la ética ambiental como presupuesto condicionante que impacta en los múltiples mecanismos de actuación social —léase la política, la economía, la educación, los sistemas jurídicos, entre otros—.2 Luego, estableceremos algunas premisas sobre la responsabilidad profesional en particular del abogado y cómo estas deberían ser integradas en una perspectiva ético-ambiental o, si se quiere, basadas en una ética de la sostenibilidad. Finalmente, interpretaremos cómo tales consideraciones debieran articularse con el ejercicio de las disciplinas jurídicas, en especial con el Derecho Ambiental, enfatizando la cuestión de la corrupción con la preocupación ambiental.

    Full Text Available Dentro de alguns poucos anos, nosso planeta contará com mais habitantes em áreas urbanas do que em áreas rurais. A urbanização desenfreada, sem mecanismos regulatórios e de controle, típica dos países periféricos, trouxe consigo enormes repercussões na saúde da população. Problemas como a insuficiência dos serviços básicos de saneamento, coleta e destinação adequada do lixo e condições precárias de moradia, tradicionalmente relacionados com a pobreza e o subdesenvolvimento, somam-se agora à poluição química e física do ar, da água e da terra, problemas ambientais antes considerados "modernos". Novamente, é sobre as populações mais carentes que recai a maior parte dos efeitos negativos da urbanização, gerando uma situação de extrema desigualdade e iniqüidade ambiental e em saúde. Para reverter esse quadro é preciso que haja uma reincorporação das questões do meio ambiente nas políticas de saúde, e a integração dos objetivos da saúde ambiental numa ampla estratégia de desenvolvimento sustentável. Uma abordagem mais integrada, com mecanismos intersetoriais que possibilitem um diálogo amplo entre as partes, trará enormes benefícios na conquista de melhores condições de vida nas cidades. A saúde ambiental hoje tem o desafio de promover uma melhor qualidade de vida e saúde nas cidades e a oportunidade de enfrentar o absurdo quadro de exclusão social, sob a perspectiva da eqüidade.In a matter of few years there will be more urban than rural dwellers worldwide.

El artículo examina esta situación, concentrándose en el papel que desempeña la ciencia en las soluciones políticas propuestas, como caso para discutir la capacidad de los mecanismos de gobernanza ambiental neoliberal para solucionar crisis ambientales y económicas. La pregunta que guía el trabajo es: ¿cuál fue el rol de la ciencia en la política ambiental para la industria? El argumento promovido es que la crisis representa un momento de reestructuración de la relación sociedad-naturaleza, en el cual se redefinieron mecanismos de propiedad, control y acceso a recursos naturales, pero en el que, pese al discurso neoliberal de confianza en los expertos y la ciencia como elementos de toma de decisiones, la información científica tuvo escasa relevancia.The Chilean salmon industry recently experienced a crisis due to an outbreak of the ISA virus. The article examines the crisis focusing on the role of science in the policy solutions proposed, to discuss the real capacity of neoliberal environmental governance mechanisms to solve environmental and economic crisis. The question guiding this research is, which was the role of science in environmental policy createdfor the salmon industry? The argument is that the crisis represents a reestructuring of the relationship between society and nature through the redefinition of property rights, control and access to natural resources, but in which, in spite of a neoliberal discourse of trust in experts and science as elements of decision making, scientific information had little relevance.

We also contribute to the technical and political debate on governmental regulations of forest environmental accounting in European Union. We have measured the environmental goods and services consumed by private landowners and public visitors through the contingent valuation technique. We have estimated the value of mushrooms gathering by public visitors in the Scotch Pine Forests of the Sierra de Guadarrama taking the price and harvest from the mushroom market in Pinar Grande (Soria. The value for carbon estimated accounts for the avoided damage of the greenhouse effect mitigation due to the sequestration of the atmospheric carbon dioxide. The environmental valuations show that the private environmental profitability rates in the Alcornocales Natural Park and in the Sierra de Guadarrama are 2.13 % and 3.43 %, in relation to their corresponding land market prices.

En este sentido, el desastre nos es natural, pero sí los fenómenos meteorológicos, geológicos o biológicos que lo provoca, los cuales afectan el medio ambiente físico de las criaturas vivientes. Considerando el estado de Sinaloa como un territorio local, este no está exento de las contradicciones medioambientales (riesgos y crisis o los desastres tales como ondas de calor, sequía, inundaciones, ciclones, heladas, granizadas y otros tipos de tormentas. La falta de interés de la sociedad local de tomar parte en la apropiación del riesgo y de sus implicaciones contribuye con estas contradicciones.

    2015-11-01

    We investigated experimentally the effects of ambient turbulence on a particle plume. Homogeneous and isotropic turbulent ambient water was generated by a random jet array in a glass tank. Glass beads of different particle diameters were released continuously into this turbulent ambient using a submerged hourglass, forming particle plumes with a constant efflux velocity; different initial velocities were tested for each particle size. We focused on the region in which the integral length scale of the ambient eddies is larger than that of the particle plume size. Following the arguments of Hunt (1994) and the observation of Hubner (2004) on a single-phase plume, it is expected that in this region, the internal structure or Lagrangian spreading of the particle plume, will not be significantly affected, but the plume centerline would meander due to the ambient turbulence leading to an increase in the Eulerian width. In the presentation, first, we will present our preliminary experimental data which showed that this is also true for two-phase particle plumes. Second, based on this observation, we developed a theoretical framework using a stochastic approach to predict the spreading of the plume. Predictions of the model will be compared with our experimental data. This research was supported by the National Research Foundation Singapore through the Singapore MIT Alliance for Research and Technology's Center for Environmental Sensing and Modeling interdisciplinary research program.

Essa iniciativa almeja ampliar e aprofundar a compreensão da problemática ambiental cujas mudanças globais provocam desafios principalmente para comunidade científica. Trata-se de problematizar o desenvolvimento da racionalidade econômica, a partir das degradações dos recursos naturais engendradas pelo atual avanço do modelo de desenvolvimento socioeconômico. Modelo que se baseia na majoração da produtividade, se apóia na expansão tecnológica e se sustenta da exploração como se os recursos naturais fossem ainda considerados abundantes e ilimitados. A transição dessa racionalidade econômica para a racionalidade ambiental é um empreendimento buscado pelas possibilidades de conhecimento advindo das análises da fenomenologia. Entre essas possibilidades, a interdisciplinaridade indicada como necessária pela epistemologia ambiental, pode se tornar uma interessante estratégia de pesquisa, desde que, tenha como ponto de partida, as demandas externas onde se encontram os elementos da atual questão ambiental e de seus desdobramentos.

    Full Text Available INTRODUCTION: Children are an important high-risk group for helminth and protozoa infections. Daycare centers are environments where children have proven to be more susceptible to acquiring intestinal parasites. Thus, the purpose of this study was to verify the prevalence of intestinal parasites in children who attended the two daycare centers maintained by the local government of Uberlândia, State of Minas Gerais, Brazil. METHODS: Fecal samples were collected from 133 children (73 children at the Public Preschool for Early Childhood Education, PPECE A, and 60 at the PPECE B following identification according to sex and age and agreement to participate by parents or guardians who signed the free, informed consent form. The samples were examined by the Lutz method. RESULTS: Coproparasitological tests performed on 133 children showed that 29.3% of them were parasitized for enteroparasites or commensals, 6.7% of the children presented polyparasitism. Among the protozoa, Giardia lamblia were the most prevalent and Hymenolepis nana were the most frequent among the helminths. CONCLUSIONS: Thus, analysis of the results showed that intestinal parasites still represent a public health problem, especially among children and in areas where the socioeconomic and educational conditions are less favorable.INTRODUÇÃO: As crianças são importantes grupos de risco para infecções por helmintos e protozoários.

    2016-09-01

    High resolution synchrotron radiation powder diffraction shows that the average crystal structure of calcite at ambient conditions is described with the trigonal space group R 3 bar c but there is a systematic hkl-dependent Bragg peak broadening. A modelling of this anisotropic peak broadening with the microstrain model from Stephens (1999) [15] is presented. The observed lattice parameters' correlations can be described by assuming a monoclinic-type deformation of calcite crystallites. A quantitative model of this monoclinic deformation observed at ambient conditions is described with the space group C 2 / c . The monoclinic unit cell suggested at ambient conditions is related with the monoclinic unit cell reported in calcite at high pressure (Merrill and Bassett (1975) [10]).

    2008-06-05

    As part of a program to characterize and baseline selected environmental parameters in the region around the proposed repository at Yucca Mountain, Nevada, ambient radon-222 monitoring was conducted in the rural community of Amargosa Valley, the community closest to the proposed repository site. Passive integrating radon monitors and a continuous radon monitoring instrument were deployed adjacent to the Community Environmental Monitoring Program (CEMP) (http://www.cemp.dri.edu/index.html) station located in the Amargosa Valley Community Center near the library. The CEMP station provided real-time ambient gamma exposure and meteorological data used to correct the integrated radon measurements as well as verify meteorological data collected by the continuous radon monitoring instrument. Additionally, different types of environmental enclosures that housed the monitors and instrument were used to determine if particular designs influenced the ambient radon measurements.

  6. Electron microprobe identification of fibrous aerosols in ambient air

    International Nuclear Information System (INIS)

    Nuclepore filters were used for sampling fibrous particles in ambient air. The fiber counting and fiber size measurements were done by means of SEM-methods. The number of fibers, distribution of fiber lengths, and diameters were plotted. The specific identification of asbestos fibers was made by electron microprobe analysis. Certain elements such as Si, Fe, Mg, Al, Mn, Ca, and Na as well as ratios such as Fe/Si and Mg/Si proved to be approximative identification factors for ambient asbestos. Not only asbestos and glass, also many other inorganic fibrous particles were found in the urban atmosphere as well as in the atmosphere of remote regions. Fibrous gypsum, fibrous ammonium sulfates, fibrous silicates, fibrous mica, and quartz were identified among these particles. Even in remote ambient air, relatively high concentrations of fibrous particles (103-104 m-3) could be measured, although the concentration of asbestos fibers were usually smaller than 102 m-3

    Full Text Available O presente estudo tem como objetivo analisar a crise do meio ambiente sob uma abordagem epistemológica, ou seja, a partir do conhecimento produzido em relação à natureza. Verifica-se que o pensamento ocidental, manifestado pelos paradigmas da Ciência Moderna, está ligado à organização dos sistemas econômicos que reconheceram historicamente a natureza apenas como recurso e potencial de produção de capital, vindo a encontrar, por esta via, o limite entrópico da biosfera e, por conseguinte, do crescimento. Abordou-se o processo de construção do conhecimento, questionando-se a possibilidade de concepção de outras perspectivas, fundadas na inseparabilidade entre sujeito-objeto, ação-pensamento e homem-natureza. É percebida a necessidade do ser humano de se re-significar no mundo, conhecendo a complexidade da natureza e pensando além da crise ecológica.

    Full Text Available Abstract Background Impaired glucose tolerance (IGT is a prediabetic state. If IGT can be prevented from progressing to overt diabetes, hyperglycemia-related complications can be avoided. The purpose of the present study was to examine whether pioglitazone (ACTOS® can prevent progression of IGT to type 2 diabetes mellitus (T2DM in a prospective randomized, double blind, placebo controlled trial. Methods/Design 602 IGT subjects were identified with OGTT (2-hour plasma glucose = 140–199 mg/dl. In addition, IGT subjects were required to have FPG = 95–125 mg/dl and at least one other high risk characteristic. Prior to randomization all subjects had measurement of ankle-arm blood pressure, systolic/diastolic blood pressure, HbA1C, lipid profile and a subset had frequently sampled intravenous glucose tolerance test (FSIVGTT, DEXA, and ultrasound determination of carotid intima-media thickness (IMT. Following this, subjects were randomized to receive pioglitazone (45 mg/day or placebo, and returned every 2–3 months for FPG determination and annually for OGTT. Repeat carotid IMT measurement was performed at 18 months and study end. Recruitment took place over 24 months, and subjects were followed for an additional 24 months. At study end (48 months or at time of diagnosis of diabetes the OGTT, FSIVGTT, DEXA, carotid IMT, and all other measurements were repeated. Primary endpoint is conversion of IGT to T2DM based upon FPG ≥ 126 or 2-hour PG ≥ 200 mg/dl. Secondary endpoints include whether pioglitazone can: (i improve glycemic control (ii enhance insulin sensitivity, (iii augment beta cell function, (iv improve risk factors for cardiovascular disease, (v cause regression/slow progression of carotid IMT, (vi revert newly diagnosed diabetes to normal glucose tolerance. Conclusion ACT NOW is designed to determine if pioglitazone can prevent/delay progression to diabetes in high risk IGT subjects, and to define the mechanisms (improved insulin sensitivity and/or enhanced beta cell function via which pioglitazone exerts its beneficial effect on glucose metabolism to prevent/delay onset of T2DM.

    Comparisons of current and historic ocean ambient noise levels are rare, especially in the North Atlantic. Recent (2013-2014) monthly patterns in ocean ambient sound south of Bermuda were compared to those recorded at the same location in 1966. Additionally, trends in ocean traffic, in particular, Panama Canal traffic, over this time were also investigated. One year of ocean ambient noise measurements were collected in 1966 using cabled, omnidirectional hydrophones at the U.S. Navy Tudor Hill Laboratory in Bermuda, and repeat measurements were collected at the same location from June 2013-May 2014 using a High-frequency Acoustic Recording Package. Average monthly pressure spectrum levels at 44 Hz increased 2.8 ± 0.8 dB from 1966 to 2013, indicating an average increase of 0.6 dB/decade. This low level of increase may be due to topographic shielding at this site, limiting it to only southern exposure, and the limit in the number of ship transits through the Panama Canal, which did not change substantially during this time. The impending expansion of the Canal, which will enable the transit of larger ships at twice the current rate, is likely to lead to a substantial increase in ocean ambient sound at this location in the near future.

    Atmospheric selenium (Se) in aerosols was investigated using X-ray absorption near-edge structure (XANES) spectroscopy and X-ray fluorescence (XRF) microscopy. These techniques were used to determine the oxidation state and elemental associations of Se in common primary emission sources and ambient aerosols collected from the greater Atlanta area. In the majority of ambient aerosol and primary emission source samples, the spectroscopic patterns as well as the absence of elemental correlations suggest Se is in an elemental, organic, or oxide form. XRF microscopy revealed numerous Se-rich particles, or hotspots, accounting on average for ∼16% of the total Se in ambient aerosols. Hotspots contained primarily Se(0)/Se(-II). However, larger, bulk spectroscopic characterizations revealed Se(IV) as the dominant oxidation state in ambient aerosol, followed by Se(0)/Se(-II) and Se(VI). Se(IV) was the only observed oxidation state in gasoline, diesel, and coal fly ash, while biomass burning contained a combination of Se(0)/Se(-II) and Se(IV). Although the majority of Se in aerosols was in the most toxic form, the Se concentration is well below the California Environmental Protection Agency chronic exposure limit (∼20000 ng/m(3)).

    Full Text Available An unsteady, spherically symmetric, single component, diffusion controlled gas phase droplet combustion model was developed assuming infinite kinetics and no radiation effects. Finite difference technique was used to solve time dependent equations of energy and species. Adiabatic flame temperature which is important for calculating thermodynamic properties was calculated by employing a detailed method. Effects of ambient temperature and composition on important combustion parameters like adiabatic flame temperature, droplet mass burning rate, burning constant and droplet lifetime were obtained. Results indicated that flame temperature, burning constant and mass burning rate increased with an increase in ambient temperature while the droplet life time decreased. The present gas phase code was used in conjunction with the Olikara and Borman code for obtaining concentration of important species. Emission results showed that for a 100 m n- heptane droplet burning in standard atmosphere, an increase in ambient temperature led to an increase in NO and CO concentrations and a decrease in CO2 and H2O concentrations. Extinction diameter for a 3000 m n- heptane droplet burning in oxygen-helium environment was determined. Also, effects of ambient temperature and composition were obtained on droplet lifetime and mass burning rate as a function of initial droplet diameter. The present gas phase model is simple but realistic and can be incorporated in spray combustion codes.

  5. Ambient air quality observations in the Athabasca oil sands region

    International Nuclear Information System (INIS)

    Both Syncrude and Suncor have plans to develop new oil sands leases and to increase crude oil and bitumen recovery in the Athabasca oil sands region. In recognition of the effects that this will have on the environment, Suncor has proposed modifications to reduce SO2 emissions to the atmosphere, while Syncrude plans to develop additional ambient air quality, sulphur deposition and biomonitoring programs. This report discussed the ambient air quality monitoring that was undertaken in the Fort McMurray-Fort McKay airshed. Twelve continuous ambient air quality stations and 76 passive monitoring stations are maintained in the region. Environment Canada maintains eight precipitation monitoring stations in northern Alberta and Saskatchewan. Source characterization, ambient air quality and meteorology observations, air quality monitoring, and air quality data from continuous sulphur dioxide, hydrogen sulphide, nitrogen oxides, ozone, carbon monoxide, hydrocarbon, acid rain and particulates analyzers were reviewed. The documentation of all computer files used for the analysis of the air quality data is discussed in the Appendix. 47 refs., 39 tabs., 53 figs

    Comparisons of current and historic ocean ambient noise levels are rare, especially in the North Atlantic. Recent (2013-2014) monthly patterns in ocean ambient sound south of Bermuda were compared to those recorded at the same location in 1966. Additionally, trends in ocean traffic, in particular, Panama Canal traffic, over this time were also investigated. One year of ocean ambient noise measurements were collected in 1966 using cabled, omnidirectional hydrophones at the U.S. Navy Tudor Hill Laboratory in Bermuda, and repeat measurements were collected at the same location from June 2013-May 2014 using a High-frequency Acoustic Recording Package. Average monthly pressure spectrum levels at 44 Hz increased 2.8 ± 0.8 dB from 1966 to 2013, indicating an average increase of 0.6 dB/decade. This low level of increase may be due to topographic shielding at this site, limiting it to only southern exposure, and the limit in the number of ship transits through the Panama Canal, which did not change substantially during this time. The impending expansion of the Canal, which will enable the transit of larger ships at twice the current rate, is likely to lead to a substantial increase in ocean ambient sound at this location in the near future.

  2. High mortality of Red Sea zooplankton under ambient solar radiation.

    Directory of Open Access Journals (Sweden)

    Ali M Al-Aidaroos

    Full Text Available High solar radiation along with extreme transparency leads to high penetration of solar radiation in the Red Sea, potentially harmful to biota inhabiting the upper water column, including zooplankton. Here we show, based on experimental assessments of solar radiation dose-mortality curves on eight common taxa, the mortality of zooplankton in the oligotrophic waters of the Red Sea to increase steeply with ambient levels of solar radiation in the Red Sea. Responses curves linking solar radiation doses with zooplankton mortality were evaluated by exposing organisms, enclosed in quartz bottles, allowing all the wavelengths of solar radiation to penetrate, to five different levels of ambient solar radiation (100%, 21.6%, 7.2%, 3.2% and 0% of solar radiation. The maximum mortality rates under ambient solar radiation levels averaged (±standard error of the mean, SEM 18.4±5.8% h(-1, five-fold greater than the average mortality in the dark for the eight taxa tested. The UV-B radiation required for mortality rates to reach ½ of maximum values averaged (±SEM 12±5.6 h(-1% of incident UVB radiation, equivalent to the UV-B dose at 19.2±2.7 m depth in open coastal Red Sea waters. These results confirm that Red Sea zooplankton are highly vulnerable to ambient solar radiation, as a consequence of the combination of high incident radiation and high water transparency allowing deep penetration of damaging UV-B radiation. These results provide evidence of the significance of ambient solar radiation levels as a stressor of marine zooplankton communities in tropical, oligotrophic waters. Because the oligotrophic ocean extends across 70% of the ocean surface, solar radiation can be a globally-significant stressor for the ocean ecosystem, by constraining zooplankton use of the upper levels of the water column and, therefore, the efficiency of food transfer up the food web in the oligotrophic ocean.

    Alterations in heart rate variability (HRV) have been reported in rodents exposed to concentrated ambient particles (CAPs) from different regions of the United States. The goal of this study was to compare alterations in cardiac function induced by CAPs in two distinct regional atmospheres. AirCARE 1, a mobile laboratory with an EPA/Harvard fine particle (particulate matter <2.5 {micro}m; PM{sub 2.5}) concentrator was located in urban Detroit, MI, where the PM mixture is heavily influenced by motor vehicles, and in Steubenville, OH, where PM is derived primarily from long-range transport and transformation of power plant emissions, as well as from local industrial operations. Each city was studied during both winter and summer months, for a total of four sampling periods. Spontaneously hypertensive rats instrumented for electrocardiogram (ECG) telemetry were exposed to CAPs 8 h/day for 13 consecutive days during each sampling period. Heart rate (HR), and indices of HRV (standard deviation of the average normal-to-normal intervals [SDNN]; square root of the mean squared difference of successive normal-to-normal intervals [rMSSD]), were calculated for 30-minute intervals during exposures. A large suite of PM components, including nitrate, sulfate, elemental and organic carbon, and trace elements, were monitored in CAPs and ambient air. In addition, a unique sampler, the Semi-Continuous Elements in Air Sampler (SEAS) was employed to obtain every-30-minute measurements of trace elements. Positive matrix factorization (PMF) methods were applied to estimate source contributions to PM{sub 2.5}. Mixed modeling techniques were employed to determine associations between pollutants/CAPs components and HR and HRV metrics. Mean CAPs concentrations in Detroit were 518 and 357 {micro}g/m{sup 3} (summer and winter, respectively) and 487 and 252 {micro}g/m{sup 3} in Steubenville. In Detroit, significant reductions in SDNN were observed in the summer in association with cement

    Full Text Available The article presents numerical analysis of exergy for air-conditioning influenced by ambient temperature. The model of numerical simulation uses an integrated air conditioning system exposed in varied ambient temperature to observe change of the four main devices, the compressor, the condenser, the capillary, and the evaporator in correspondence to ambient temperature. The analysis devices of the four devices’s exergy influenced by the varied ambient temperature and found that the capillary has unusual increasing exergy loss vs. increasing ambient temperature in comparison to the other devices. The result shows that reducing exergy loss of the capillary influenced by the ambient temperature is the key for improving working efficiency of an air-conditioning system when influence of the ambient temperature is considered. The higher ambient temperature causes the larger pressure drop of capillary and more exergy loss.

    2009-02-27

    We describe the development and applications of novel instrumentation for photoemission spectroscopy of solid or liquid surfaces in the presence of gases under ambient conditions or pressure and temperature. The new instrument overcomes the strong scattering of electrons in gases by the use of an aperture close to the surface followed by a differentially-pumped electrostatic lens system. In addition to the scattering problem, experiments in the presence of condensed water or other liquids require the development of special sample holders to provide localized cooling. We discuss the first two generations of Ambient Pressure PhotoEmission Spectroscopy (APPES) instruments developed at synchrotron light sources (ALS in Berkeley and BESSY in Berlin), with special focus on the Berkeley instruments. Applications to environmental science and catalytic chemical research are illustrated in two examples.

    Tabatabaie, M., Sommer, S.C.

    1998-03-27

    This paper presents the results of a study to evaluate the effects of soil-structure interaction (SSI) on the ambient vibration response of the switchyard/target area (S/TA) buildings at the National Ignition Facility (NIF) presently under construction at the Lawrence Livermore National Laboratory (LLNL) in Livermore, California. This laser facility houses optical and other special equipment whose alignment stability is sensitive to vibrations caused by ambient vibrations or other vibrating sources. In evaluating the deformations and displacements of the S/TA structures, the contribution of the SSI to the overall system flexibility can be very significant. The present study examines the results of fixed-base and SSI analyses of these massive stiff structures to develop an understanding of the potential contribution of SSI to the overall system displacements and deformations. A simple procedure using a set of factors is recommended for scaling the results of fixed-base analyses to approximately account for SSI effects.

    On Line Parameter Identification Technique (OLPIT) was presented according to ambient excitation characteristics and the response cross-correlation function that is a sum of decaying sinusoids of the same form as the impulse response function of the original system. OLPIT is a new method of identification modal parameters from response of structures under ambient excitation. OLPIT is different from NExT (natural excitation technique) based on ITD method in four aspects: ① The algorithm is improved by the singular-value decomposition (SVD). ② Multi-value of br in the Ibrahim Time Domain (ITD) is avoided. ③ OLPIT is used in both SIMO (single input, multi-output) and MIMO (multi input, multi-output). ④ The precision of modal parameter identificatioin is improved. The simulation studies demonstrate that the method is effective in identifying complex modes even with close frequencies and is robust to measurement noise.

Overfiring provides capacity enhancement which comes at the expense of reduced maintenance interval and increased costs of part replacement. We consider the costs and benefits of overfiring in attempt to maximize the asset value by optimally exercising the overfire option. In addition to stochastic processes governing prices, we incorporate an exogenous productivity shock: ambient temperature. We consider how variation in ambient temperature affects the asset value through its effect on gas turbine's productivity. (author)

  1. Damage localization under ambient vibration using changes in flexibility

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

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

    This article gives a review of a recent construction, the ambient cosmological metric, and its implications for the global geometry of the universe. According to this proposal, the universe is a bounding hypersurface carrying a conformal structure and lying at the (conformal) infinity of a new, 5-geometry which satisfies the Einstein equations with fluid sources. We discuss our main results about the implied topological nature of the conformal infinity of the ambient metric, the non-existence of spacetime singularities on the boundary, as well as the validity of cosmic censorship as a direct consequence of a new principle on the boundary. Various further issues associated with this proposal are also briefly discussed.

    2013-03-01

    It has been speculated that resting muscle mechanical activity, also known as minor tremor, microvibration, and thermoregulatory tonus, has evolved to maintain core temperature in homeotherms, and may play a role in nonshivering thermogenesis. This experiment was done to determine whether resting muscle mechanical activity increases with decreasing ambient temperature. We cooled 20 healthy, human, resting, supine subjects from an ambient temperature of 40° to 12 °C over 65 min. Core temperature, midquadriceps mechanomyography, surface electromyography, and oxygen consumption (VO2) were recorded. Resting muscle mechanical and electrical activity in the absence of shivering increased significantly at temperatures below 21.5 °C. Women defended core temperature more effectively than men, and showed increased resting muscle activity earlier than men. Metabolism measured by VO2 correlated with resting muscle mechanical activity (R = 0.65; p = 0.01). Resting muscle mechanical activity may have evolved, in part, to maintain core temperature in the face of mild cooling.

    2016-01-01

    Background: Preterm birth is a major perinatal health problem, but factors leading to it are still not completely understood. Objectives: Our goal was to identify the relation between acute increase in ambient air pollution in a few hours before onset of labor and the risk of preterm birth. Methods: We collected registered birth outcome data and hourly ambient air pollution measurements during 2009‒2013 in Brisbane, Australia. Using a time-stratified case-crossover design and conditional logistic regression models with natural cubic splines, we assessed the shape of air pollution-preterm birth curve, after controlling for potential confounders. We also examined the effect modification of other factors. Results: The association between air pollution [nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO)] and preterm birth was nonlinear. Threshold concentrations for the mean of 0‒24 hr NO2, 24‒48 hr SO2, and 24‒48 hr CO before onset of labor were 7.6 parts per billion (ppb), 3.8 ppb, and 162.5 ppb, respectively. Increases in air pollution concentrations above thresholds were associated with increased risks of preterm birth. The odds ratios of preterm birth at the 95th percentile of NO2, SO2, and CO against the thresholds were 1.17 (95% CI: 1.08, 1.27), 1.01 (95% CI: 0.99, 1.04), and 1.18 (95% CI: 1.06, 1.32), respectively. The associations were modified by demographic factors, such as maternal smoking and socioeconomic status. Conclusion: Acute increases in ambient air pollution concentrations above certain levels before onset of labor may stimulate preterm birth. Citation: Li S, Guo Y, Williams G. 2016.

  1. SCHEMA CONGRUITY – A BASIS FOR EVALUATING AMBIENT ADVERTISING EFFECTIVENESS

    Directory of Open Access Journals (Sweden)

    Jurca Maria Alina

    2013-07-01

    Full Text Available The purpose of this paper is to develop a theoretical basis for evaluating ambient advertising in relation to the schema. Ambient advertising, a creative form of out-of-home advertising that conveys direct and contextual messages by using and often altering existing elements of the environment in a way that surprises the target audience, appears to be a solution to the increasing clutter from the media. This study draws on the schema congruity theory to offer a better understanding of how consumers are processing information received from advertisements. Schemas are organized structures of knowledge and expectations that consumers develop in order to categorize the incoming information, and that they access every time they are experiencing a new situation. The schema-based approach is important in understanding consumer behavior because consumers are facing an environment filled with similar brands and products promoted by ads that sound and look alike. According to schema congruity theory information perceived as schema congruent offers a confortable feeling of familiarity and generates limited cognitive processing, whereas schema incongruent information generates surprise and triggers extensive cognitive processing in order to help individual make sense of the unusual situation. Taking into consideration the combination of the different levels of expectancy and relevancy there have been identified three congruency situations: extreme congruity, moderate incongruity and extreme incongruity. Existing research shows that moderate incongruent information offers the best results in recall and recognition and also the highest affect levels compared to extreme congruity and extreme incongruity. Based on evidence from literature this study attempts to position ambient advertising in the moderate incongruity category, thus theoretically proving the assumed effectiveness of this promotional tool. Therefore, this paper is a starting point in bringing the

    Full Text Available En el noroeste de México la producción de camarón cultivado es considerada como una de las más importantes de América Latina. Sin embargo, se presentan grandes pérdidas económicas asociadas a enfermedades durante su cultivo, aunado a la intervención intensiva que generan las prácticas acuícolas que van degradando el medio ambiente. Esto es, primero, por la utilización del agua que recibe grandes cantidades de desechos, así como el alimento no consumido por los organismos que se sedimenta en el fondo marino, dañando al ambiente que es habitado no solo por los organismos cultivados sino también por otras especies. Segundo, porque se introducen antibióticos y sustancias químicas al ecosistema durante el desarrollo de la actividad. Por ello, fue necesario evaluar el efecto de un antibiótico y un biocida sobre las bacterias que habitan un sistema de cultivo, en relación al desarrollo de resistencia y la presencia de lesiones en los distintos órganos de camarón Litopenaeus vannamei. El empleo de los compuestos puede generar una huella ecológica, ya que se considera que un sistema de cultivo tiene una influencia en el medio ambiente diez mil veces superior a su superficie. El impacto tiene un costo ambiental, económico y social y la pregunta que surge es si esto es sustentable en el tiempo.

  9. Ambient dose measurement in some CT departments in Khartoum State

    International Nuclear Information System (INIS)

    Computerized Tomography (CT) is now one of the most important radiological examinations world wide.The frequency of CT examinations is increasing rapidly from 2% of all radiological examinations in some countries a decade age to 10-15% now. During the imaging procedure, staff may expose to a significant dose. Therefore, ambient dose measurement is important in the shortage of regular personal monitoring in sudan. This study intended to evaluate the ambient dose at some CT departments (Medical Military hospital, Alamal National Hospital, Elnelin Diagnostic Center and Modern Medical Centre). These departments were equipped with daul, 16 and 64 multi detector CT machines. A survey meter (Radios) was used to measure ambient doses in three locations: Doors, Control Rooms and Adjacent Rooms. The ambient dose equivalent (scatter dose) was measured at various distances from the isocenter of the CT unit at various angles to establish isodose cartography. The mean and range of radiation at control room is 10.00-0.20 and mean (7.05μSv/hr,) reception 1.0-0 (0.40) and doors 4.00-100.00 (73.5) for height 1 meter above the ground. For height 2 meters at control room 0-10.00 (6,75), reception 0-90.00 (30) at door 9.00-90.00 (49.50). This study confirms that low levels of radiation dose are received by staff during CT imaging and these levels are within safe limits as prescribed by the national and international regulations.

  10. Shear velocity of the Rotokawa geothermal field using ambient noise

    Science.gov (United States)

    Civilini, F.; Savage, M. K.; Townend, J.

    2014-12-01

    Ambient noise correlation is an increasingly popular seismological technique that uses the ambient seismic noise recorded at two stations to construct an empirical Green's function. Applications of this technique include determining shear velocity structure and attenuation. An advantage of ambient noise is that it does not rely on external sources of seismic energy such as local or teleseismic earthquakes. This method has been used in the geothermal industry to determine the depths at which magmatic processes occur, to distinguish between production and non-production areas, and to observe seismic velocity perturbations associated with fluid extraction. We will present a velocity model for the Rotokawa geothermal field near Taupo, New Zealand, produced from ambient noise cross correlations. Production at Rotokawa is based on the "Rotokawa A" combined cycle power station established in 1997 and the "Nga Awa Purua" triple flash power plant established in 2010. Rotokawa Joint Venture, a partnership between Mighty River Power and Tauhara North No. 2 Trust currently operates 174 MW of generation at Rotokawa. An array of short period seismometers was installed in 2008 and occupies an area of roughly 5 square kilometers around the site. Although both cultural and natural noise sources are recorded at the stations, the instrument separation distance provides a unique challenge for analyzing cross correlations produced by both signal types. The inter-station spacing is on the order of a few kilometers, so waves from cultural sources generally are not coherent from one station to the other, while the wavelength produced by natural noise is greater than the station separation. Velocity models produced from these two source types will be compared to known geological models of the site. Depending on the amount of data needed to adequately construct cross-correlations, a time-dependent model of velocity will be established and compared with geothermal production processes.

  15. Ambient sesquiterpene concentration and its link to air ion measurements

    Directory of Open Access Journals (Sweden)

    2006-12-01

    Full Text Available Ambient air ion size distributions have been measured continuously at the Finnish boreal forest site in Hyytiälä since spring 2003. In general, these measurements show a maximum of air ions below 1.0 nm in diameter. But this physical characterization does not provide any information about the ion's chemical composition, which is one key question regarding the explanation of nucleation events observed. In this study we propose a link of the observed maximum of negative air ions between 0.56 and 0.75 nm to the so-called stabilised Criegee biradical, formed in the reaction of biogenic sesquiterpenes with ozone and predominantly destroyed by its reaction with ambient water vapour. Calculations of the electron and proton affinities of 120 kJ mol−1 (1.24 eV and of 960 kJ mol−1 support this link. Other possible candidates such as sulphuric acid derived clusters are unable to explain the observations made. By using this approach, we are able to calculate the ambient concentration of sesquiterpenes at the air ion instrument inlet with a high time resolution on the daily and seasonal scale. The estimated concentration is found to reveal the same seasonal pattern as emission measurements conducted at shoot level. As expected for biogenic VOCs, the concentration is obtained highest during summer (maximum values of about 100 pptv and smallest during winter (minimum less than 1 pptv. Because of the sesquiterpenes high reactivity and its low ambient concentrations, this approach can be a first step in understanding their emission and their impact on atmospheric chemistry in more detail. The findings presented are highly relevant for emission budgets too, since boreal forests are extended over large areas of the globe.

    This paper offers a new mechanism in order to Nash-implement a Pareto optimal level of ambient pollution. As usual in the literature on non point source pollution, the proposed scheme is not conditional on individual emissions, since they are not observable; rather it is conditional on aggregate emission. But the novelty here is that we do not assume the 10 regulator knows the agents' preferences, with which he could identify the target level of aggregate emission. Our mechanism dispenses wit...

  3. Ambient temperature cadmium zinc telluride radiation detector and amplifier circuit

    International Nuclear Information System (INIS)

    A low noise, low power consumption, compact, ambient temperature signal amplifier for a Cadmium Zinc Telluride (CZT) radiation detector is disclosed. The amplifier can be used within a larger system (e.g., including a multi-channel analyzer) to allow isotopic analysis of radionuclides in the field. In one embodiment, the circuit stages of the low power, low noise amplifier are constructed using integrated circuit (IC) amplifiers , rather than discrete components, and include a very low noise, high gain, high bandwidth dual part preamplification stage, an amplification stage, and an filter stage. The low noise, low power consumption, compact, ambient temperature amplifier enables the CZT detector to achieve both the efficiency required to determine the presence of radionuclides and the resolution necessary to perform isotopic analysis to perform nuclear material identification. The present low noise, low power, compact, ambient temperature amplifier enables a CZT detector to achieve resolution of less than 3% full width at half maximum at 122 keV for a Cobalt-57 isotope source. By using IC circuits and using only a single 12 volt supply and ground, the novel amplifier provides significant power savings and is well suited for prolonged portable in-field use and does not require heavy, bulky power supply components. 9 figs

    Localization is essential in wireless sensor networks. To our knowledge, no prior work has utilized low-cost devices for collaborative localization based on only ambient sound, without the support of local infrastructure. The reason may be the fact that most low-cost devices are indeterministic and suffer from uncertain input latencies. This uncertainty makes accurate localization challenging. Therefore, we present a collaborative localization algorithm (Cooperative Localization on Android with ambient Sound Sources (CLASS)) that simultaneously localizes the position of indeterministic devices and ambient sound sources without local infrastructure. The CLASS algorithm deals with the uncertainty by splitting the devices into subsets so that outliers can be removed from the time difference of arrival values and localization results. Since Android is indeterministic, we select Android devices to evaluate our approach. The algorithm is evaluated with an outdoor experiment and achieves a mean Root Mean Square Error (RMSE) of 2.18 m with a standard deviation of 0.22 m. Estimated directions towards the sound sources have a mean RMSE of 17.5° and a standard deviation of 2.3°. These results show that it is feasible to simultaneously achieve a relative positioning of both devices and sound sources with sufficient accuracy, even when using non-deterministic devices and platforms, such as Android.

    International Nuclear Information System (INIS)

    Sixteen species of native detector plants for ambient ozone have been identified for use in Central and Eastern Europe. They include the forbs Alchemilla sp., Astrantia major, Centuarea nigra, Centauria scabiosa, Impatiens parviflora, Lapsana communis, Rumex acetosa and Senecio subalpinus; the shrubs Corylus avellana, Cornus sanguinea and Sambucus racemosa; the trees Alnus incana, Pinus cembra and Sorbus aucuparia; and the vines Humulus lupulus and Parthenocissus quinquefolia. Sensitivity to ozone and symptoms have been verified under controlled exposure conditions. Under these conditions, symptom incidence, intensity and appearance often changed with time after removal from exposure chambers. Ozone sensitivity for four species: Astrantia major, Centuarea nigra, C. scabiosa and Humulus lupulus are reported here for the first time. The other 12 species have also been confirmed by others in Western Europe. It is recommended that these detector bioindicator species be used in conjunction with ozone monitors and passive samplers so that injury symptoms incidence can be used to give biological significance to monitored ambient ozone data. - Sixteen species of verified bioindicator plants for ambient ozone are available for use in Central and Eastern Europe

  6. Ambient air monitoring for mercury around an industrial complex

    International Nuclear Information System (INIS)

    Public and scientific interest in mercury in the environment has experienced an upsurge in the past few years, due in part to disclosures that fish in certain waters, which have apparently received no direct industrial discharges, were contaminated with mercury. Atmospheric releases of mercury from fossil fuel energy generators, waste incinerators and other industrial sources are suspected to be contributing to this problem. Such releases can be evaluated in a variety of ways, including stack sampling, material balance studies, soil/vegetation sampling and ambient air monitoring. Ambient air monitoring of mercury presents significant challenges because of the typically low concentrations (ng/m3) encountered and numerous opportunities for sample contamination or analyte loss. There are presently no EPA-approved protocols for such sampling and analysis. Elemental mercury was used in large quantities at a nuclear weapons plant in Oak Ridge, Tennessee between 1950 and 1963 in a process similar to chloralkali production. Soil and water contamination with mercury were known to be present at the facility but outdoor ambient air contamination had not been investigated prior to the present study. In addition, one large building still contained original process equipment with mercury residuals. The objectives of this study were to establish a monitoring network for mercury which could be used (1) to demonstrate whether or not human health and the environment was being protected, and (2), to establish a decommissioning activities at the facility

  8. Ambient temperature perception in papaya for papaya ringspot virus interaction.

    Temperature dramatically affects the host-virus interaction. Outbreaks of viral diseases are frequently associated with the ambient temperature required for host development. Using papaya as a host and Papaya ringspot virus (PRSV) as a pathogen, we studied the effect of temperature on the intensity of disease symptoms and virus accumulation. The phenotypic expression of symptoms and viral accumulation were found to be maximum at ambient temperature (26-31 degrees C) of papaya cultivation. However, there was a drastic difference, 10 degrees C above and below the ambient temperature. The underlying mechanism of these well-known observations are not yet understood completely; however, these observations might help find answers in RNA silencing mechanism of plants. Since viral-derived silencing suppressor proteins play a significant role in RNA silencing mechanism, here we show that PRSV-derived Helper component proteinase (HC-Pro) protein has an affinity for small RNAs in a temperature-dependent manner. This suggested the probable role of HC-Pro in the temperature-regulated host-virus relationship.

    Recent innovations in ambient ionization technology for the direct analysis of various samples in their native environment facilitate the development and applications of mass spectrometry in natural science. Presented here is a novel, convenient and flame-based ambient ionization method for mass spectrometric analysis of organic compounds, termed as the ambient flame ionization (AFI) ion source. The key features of AFI ion source were no requirement of (high) voltages, laser beams and spray gases, but just using small size of n-butane flame (height approximately 1 cm, about 500 oC) to accomplish the rapid desorption and ionization for direct analysis of gaseous-, liquid- and solid-phase organic compounds, as well as real-world samples. This method has high sensitivity with a limit of detection of 1 picogram for propyphenazone, which allows consuming trace amount of samples. Compared to previous ionization methods, this ion source device is extremely simple, maintain-free, low-cost, user-friendly so that even an ordinary lighter (with n-butane as fuel) can achieve efficient ionization. A new orientation to mass spectrometry ion source exploitation might emerge from such a convenient, easy and inexpensive AFI ion source.

    The knowledge of stoichiometries of alkaline-earth metal nitrides, where nitrogen can exist in polynitrogen forms, is of significant interest for understanding nitrogen bonding and its applications in energy storage. For calcium nitrides, there were three known crystalline forms, CaN2, Ca2N, and Ca3N2, at ambient conditions. In the present study, we demonstrated that there are more stable forms of calcium nitrides than what is already known to exist at ambient and high pressures. Using a global structure searching method, we theoretically explored the phase diagram of CaNx and discovered a series of new compounds in this family. In particular, we found a new CaN phase that is thermodynamically stable at ambient conditions, which may be synthesized using CaN2 and Ca2N. Four other stoichiometries, namely, Ca2N3, CaN3, CaN4, and CaN5, were shown to be stable under high pressure. The predicted CaNx compounds contain a rich variety of polynitrogen forms ranging from small molecules (N2, N4, N5, and N6) to extended chains (N∞). Because of the large energy difference between the single and triple nitrogen bonds, dissociation of the CaNx crystals with polynitrogens is expected to be highly exothermic, making them as potential high-energy-density materials.

  15. Sampling frequency guidance for ambient air toxics monitoring.

    Bortnick, Steven M; Stetzer, Shannon L

    2002-07-01

    The U.S. Environmental Protection Agency (EPA) is in the process of designing a national network to monitor hazardous air pollutants (HAPs), also known as air toxics. The purposes of the expanded monitoring are to (1) characterize ambient concentrations in representative areas; (2) provide data to support and evaluate dispersion and receptor models; and (3) establish trends and evaluate the effectiveness of HAP emission reduction strategies. Existing air toxics data, in the form of an archive compiled by EPA's Office of Air Quality Planning and Standards (OAQPS), are used in this paper to examine the relationship between estimated annual average (AA) HAP concentrations and their associated variability. The goal is to assess the accuracy, or bias and precision, with which the AA can be estimated as a function of ambient concentration levels and sampling frequency. The results suggest that, for several air toxics, a sampling schedule of 1 in 3 days (1:3) or 1:6 days maybe appropriate for meeting some of the general objectives of the national network, with the more intense sampling rate being recommended for areas expected to exhibit relatively high ambient levels.

    Mass spectrometry imaging (MSI) is a powerful analytical technique that enables label-free spatial localization and identification of molecules in complex samples.1-4 MSI applications range from forensics5 to clinical research6 and from understanding microbial communication7-8 to imaging biomolecules in tissues.1, 9-10 Recently, MSI protocols have been reviewed.11 Ambient ionization techniques enable direct analysis of complex samples under atmospheric pressure without special sample pretreatment.3, 12-16 In fact, in ambient ionization mass spectrometry, sample processing (e.g., extraction, dilution, preconcentration, or desorption) occurs during the analysis.17 This substantially speeds up analysis and eliminates any possible effects of sample preparation on the localization of molecules in the sample.3, 8, 12-14, 18-20 Venter and co-workers have classified ambient ionization techniques into three major categories based on the sample processing steps involved: 1) liquid extraction techniques, in which analyte molecules are removed from the sample and extracted into a solvent prior to ionization; 2) desorption techniques capable of generating free ions directly from substrates; and 3) desorption techniques that produce larger particles subsequently captured by an electrospray plume and ionized.17 This review focuses on localized analysis and ambient imaging of complex samples using a subset of ambient ionization methods broadly defined as “liquid extraction techniques” based on the classification introduced by Venter and co-workers.17 Specifically, we include techniques where analyte molecules are desorbed from solid or liquid samples using charged droplet bombardment, liquid extraction, physisorption, chemisorption, mechanical force, laser ablation, or laser capture microdissection. Analyte extraction is followed by soft ionization that generates ions corresponding to intact species. Some of the key advantages of liquid extraction techniques include the ease

    Background: Olfactory dysfunction affects millions of people worldwide. This sensory impairment is associated with neurodegenerative disease and significantly decreased quality of life. Exposure to airborne pollutants has been implicated in olfactory decline, likely due to the anatomic susceptibility of the olfactory nerve to the environment. Historically, studies have focused on occupational exposures, but more recent studies have considered effects from exposure to ambient air pollutants. Objectives: To examine all relevant human data evaluating a link between ambient pollution exposure and olfaction and to review supporting animal data in order to examine potential mechanisms for pollution-associated olfactory loss. Methods: We identified and reviewed relevant articles from 1950 to 2015 using PubMed and Web of Science and focusing on human epidemiologic and pathophysiologic studies. Animal studies were included only to support pertinent data on humans. We reviewed findings from these studies evaluating a relationship between environmental pollutant exposure and olfactory function. Results: We identified and reviewed 17 articles, with 1 additional article added from a bibliography search, for a total of 18 human studies. There is evidence in human epidemiologic and pathologic studies that increased exposure to ambient air pollutants is associated with olfactory dysfunction. However, most studies have used proxies for pollution exposure in small samples of convenience. Human pathologic studies, with supporting animal work, have also shown that air pollution can contact the olfactory epithelium, translocate to the olfactory bulb, and migrate to the olfactory cortex. Pollutants can deposit at each location, causing direct damage and disruption of tissue morphology or inducing local inflammation and cellular stress responses. Conclusions: Ambient air pollution may impact human olfactory function. Additional studies are needed to examine air pollution

    In the past several years, geological energy technologies receive growing attention and have been initiated in or close to urban areas. Some of these technologies involve injecting fluids into the subsurface (e.g., oil and gas development, waste disposal, and geothermal energy development) and have been found or suspected to cause small to moderate sized earthquakes. These earthquakes, which may have gone unnoticed in the past when they occurred in remote sparsely populated areas, are now posing a considerable risk for the public acceptance of these technologies in urban areas. The permanent termination of the EGS project in Basel, Switzerland after a number of induced ML~3 (minor) earthquakes in 2006 is one prominent example. It is therefore essential to the future development and success of these geological energy technologies to develop strategies for managing induced seismicity and keeping the size of induced earthquake at a level that is acceptable to all stakeholders. Most guidelines and recommendations on induced seismicity published since the 1970ies conclude that an indispensable component of such a strategy is the establishment of seismic monitoring in an early stage of a project. This is because an appropriate seismic monitoring is the only way to detect and locate induced microearthquakes with sufficient certainty to develop an understanding of the seismic and geomechanical response of the reservoir to the geotechnical operation. In addition, seismic monitoring lays the foundation for the establishment of advanced traffic light systems and is therefore an important confidence building measure towards the local population and authorities. Due to this development an increasing number of seismic monitoring networks are being installed in densely populated areas with strongly heterogeneous, and unfavorable ambient noise conditions. This poses a major challenge on the network design process, which aims to find the sensor geometry that optimizes the

    2015-08-01

    The influence of ambient temperature is a big challenge to robust infrared face recognition. This paper proposes a new ambient temperature normalization algorithm to improve the performance of infrared face recognition under variable ambient temperatures. Based on statistical regression theory, a second order polynomial model is learned to describe the ambient temperature's impact on infrared face image. Then, infrared image was normalized to reference ambient temperature by the second order polynomial model. Finally, this normalization method is applied to infrared face recognition to verify its efficiency. The experiments demonstrate that the proposed temperature normalization method is feasible and can significantly improve the robustness of infrared face recognition.

    Full Text Available Cuando Panamá y Colombia se separaron a comienzos de este siglo, el gobierno panameño intentó reforzar sus fronteras, utilizando los puestos escolares y policiales como medida. Los kunas precisamente habitaban esta línea fronteriza entre los dos países. Las primeras leyes dictadas se encaminaron a la civilización de este pueblo. Y la educación estaba dirigida a conseguir el afianzamiento de la nación; y para ello se emplearon todos los medios: becas, creación de internados... pues los estudiantes iban a ayudar a los mandatarios a cambiar las ideas de los nativos, llegando incluso a perder la vida. Las misiones católicas y protestantes jugaron también un papel importante hasta el momento de la creación de la primera escuela en i9±5. Pero esta educación creó división entre los propios indios y se llegó hasta una revolución en 1925 que pretendía la separación de Panamá y frenar los abusos que se estaban cometiendo bajo la bandera de la civilización.

    Full Text Available O presente artigo trata de uma análise da ação governamental para o controle do uso dos recursos natno Brasil, desde o descobrimento, em 1500. Teve como objetivo compreender o processo de formulação e execução de políticas ambientais, considerando a evolução de conceitos, regras e instituições do período colonial até os dias atuais, caracterizando as bases históricas, institucionais e legais que moldaram a atual governança ambiental brasileira. A pesquisa foi realizada consultando referências bibliográficas e documentos governamentais com dados e informações diversos. Pode-se observar que ao longo da história do País, a ação governamental concentrou-se nas ações de comando e controle, com regras e instituições específicas para determinados recursos naturais, com pouca ou nenhuma integração com outras políticas ou processos gerenciais de uso de recursos naturais, situação que mudou significativamente após a instituição da Lei nº 6.938/81, da Política Nacional do Meio Ambiente, quando houve correspondência da evolução da gestão ambiental no Brasil com os conceitos, princípios, diretrizes e critérios de governança ambiental e seus resultados. Apesar dos avanços em direção aos critérios de reforma e modernização do Estado como descentralização, participação, democratização, capacitação gerencial, eficiência e eficácia, a relação da sociedade, do Governo e do setor privado com a natureza ainda reflete uma visão colonial utilitarista, imediatista e de uso insustentável dos recursos naturais, aliada a problemas de execução das normas e regras, causando degradação ambiental e comprometendo o desenvolvimento sustentável. Indicam a necessidade de se avaliar mais criticamente os alcances da Política Nacional do Meio Ambiente em função da contínua perda dos recursos e serviços ambientais e o elevado padrão de consumo da sociedade em bases não sustentáveis, requerendo mudanças de

  17. The importance of ambient sound level to characterise anuran habitat.

    Directory of Open Access Journals (Sweden)

    Sandra Goutte

    Full Text Available Habitat characterisation is a pivotal step of any animal ecology study. The choice of variables used to describe habitats is crucial and need to be relevant to the ecology and behaviour of the species, in order to reflect biologically meaningful distribution patterns. In many species, acoustic communication is critical to individuals' interactions, and it is expected that ambient acoustic conditions impact their local distribution. Yet, classic animal ecology rarely integrates an acoustic dimension in habitat descriptions. Here we show that ambient sound pressure level (SPL is a strong predictor of calling site selection in acoustically active frog species. In comparison to six other habitat-related variables (i.e. air and water temperature, depth, width and slope of the stream, substrate, SPL had the most important explanatory power in microhabitat selection for the 34 sampled species. Ambient noise was particularly useful in differentiating two stream-associated guilds: torrents and calmer streams dwelling species. Guild definitions were strongly supported by SPL, whereas slope, which is commonly used in stream-associated habitat, had a weak explanatory power. Moreover, slope measures are non-standardized across studies and are difficult to assess at small scale. We argue that including an acoustic descriptor will improve habitat-species analyses for many acoustically active taxa. SPL integrates habitat topology and temporal information (such as weather and hour of the day, for example and is a simple and precise measure. We suggest that habitat description in animal ecology should include an acoustic measure such as noise level because it may explain previously misunderstood distribution patterns.

Esta nueva mentalidad supone una revisión radical del talante humano ante la naturaleza no por pura complacencia estética, ni por un sentimentalismo vacío de contenido, sino por la convicción de que la humanidad forma un todo integrado en la biosfera y que el deterioro ambiental es, al mismo tiempo, una degradación del medio humano.

    The effect of ambient air pollution on panic disorder in the general population has not yet been thoroughly elucidated, although the occurrence of panic disorder in workers exposed to organic solvents has been reported previously. We investigated the association of ambient air pollution with the risk of panic attack-related emergency department visits. Using health insurance claims, we collected data from emergency department visits for panic attacks in Seoul, Republic of Korea (2005-2009). Daily air pollutant concentrations were obtained using automatic monitoring system data. We conducted a time-series study using a generalized additive model with Poisson distribution, which included spline variables (date of visit, daily mean temperature, and relative humidity) and parametric variables (daily mean air pollutant concentration, national holiday, and day of the week). In addition to single lag models (lag1 to lag3), cumulative lag models (lag0-1 to lag0-3) were constructed using moving-average concentrations on the days leading up to the visit. The risk was expressed as relative risk (RR) per one standard deviation of each air pollutant and its 95% confidence interval (95% CI). A total of 2320 emergency department visits for panic attacks were observed during the study period. The adjusted RR of panic attack-related emergency department visits was 1.051 (95% CI, 1.014-1.090) for same-day exposure to ozone. In cumulative models, adjusted RRs were 1.068 (1.029-1.107) in lag0-2 and 1.074 (1.035-1.114) in lag0-3. The ambient ozone concentration was significantly associated with emergency department visits for panic attacks. PMID:25669697

  20. Crustal structure of Australia from ambient seismic noise tomography

    Surface wave tomography for Australian crustal structure has been carried out using group velocity measurements in the period range 1-32 s extracted from stacked correlations of ambient noise between station pairs. Both Rayleigh wave and Love wave group velocity maps are constructed for each period using the vertical and transverse component of the Green's function estimates from the ambient noise. The full suite of portable broadband deployments and permanent stations on the continent have been used with over 250 stations in all and up to 7500 paths. The permanent stations provide a useful link between the various shorter-term portable deployments. At each period the group velocity maps are constructed with a fully nonlinear tomographic inversion exploiting a subspace technique and the Fast Marching Method for wavefront tracking. For Rayleigh waves the continental coverage is good enough to allow the construction of a 3D shear wavespeed model in a two stage approach. Local group dispersion information is collated for a distribution of points across the continent and inverted for a 1D SV wavespeed profile using a Neighbourhood Algorithm method. The resulting set of 1D models are then interpolated to produce the final 3D wavespeed model. The group velocity maps show the strong influence of thick sediments at shorter periods, and distinct fast zones associated with cratonic regions. Below the sediments the 3D shear wavespeed model displays significant heterogeneity with only moderate correlation with surface tectonic features. For example, there is no evident expression of the Tasman Line marking the eastern edge of Precambrian outcrop. The large number of available inter-station paths extracted from the ambient noise analysis provide detailed shear wavespeed information for crustal structure across the Australian continent for the first time, including regions where there was no prior sampling because of difficult logistics.
