    Full Text Available Estudio descriptivo, cuyo objetivo fue identificar las deficiencias de autocuidado de ancianas institucionalizadas. Desarrollado durante en 2009, en hogar de ancianos en Fortaleza - CE, Brasil. Para recoger los datos, se utilizó entrevista semiestructurada, centrándose en factores condicionantes y requisitos de autocuidado, aplicadas a 24 ancianas. Los resultados señalaron que las principales razones que llevaron a la institucionalización fueron: ausencia de familiares, falta de disponibilidad de niños para prestación de la atención y necesidad de vivir en ambiente de paz, sin conflictos. Déficit de autocuidado se relacionaron con los factores: hidratación, eliminación, sueño y descanso, mantenimiento de la salud, interacción social, adaptación institucional para el medio ambiente y cambios en el ciclo de vida, control de problemas de salud crónicos. De las demandas y/o necesidades de autocuidado identificadas, el sistema de apoyo educativo de Orem podrá ofrecer intervenciones de enfermería con objetivo de involucrar a las ancianas en acciones de autocuidado.

    2011-12-01

    Full Text Available A consolidação de políticas públicas de educação ambiental no Brasil permite o aprofundamento de reflexões conceituais e implicações políticas destas, o que contribui para o posicionamento dos agentes sociais envolvidos. No presente artigo, apresentamos as concepções hegemônicas de Estado e sociedade civil no campo, tendo por referência a análise crítica do discurso de um caso empírico concreto: a chamada pública do Ministério do Meio Ambiente para Coletivo Educadores, de 2006; problematizando-as à luz de um referencial inserido na tradição marxista. Com isso, após a análise detalhada do documento, é possível afirmar que tais concepções hegemônicas se inserem no quadro teórico e discursivo da denominada “Terceira Via” e no modelo de Estado Gerencial, propostas estas que não contribuem diretamente para o avanço das lutas sociais de cunho emancipatório, tal como preconizado pela Educação Ambiental Crítica.

    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.

As variáveis analisadas foram: amplitude de deslocamento do centro de pressão (COP na direção ântero-posterior, médio-lateral e velocidade de deslocamento do COP. Foi aplicado o teste Wilcoxon para a comparação entre as avaliações pré e pós a intervenção. Foi observada uma melhora no controle postural após a intervenção, visto que ocorreu diminuição do deslocamento do centro de pressão, principalmente na direção ântero-posterior. Para o grupo de idosas institucionalizadas participantes deste estudo, a hidrocinesioterapia realizada em piscina rasa foi capaz de melhorar o equilíbrio postural.

  12. E agora ... de quem, cuidarei?”: o cuidar na percepção de idosas institucionalizadas e não institucionalizadas

    Camila Vianna Duarte

    Full Text Available O perfil demográfico brasileiro tem mudado as características do envelhecimento. Este trabalho objetiva investigar a percepção de idosas sobre o cuidado consigo e com o outro, comparando-a com suas necessidades atuais de cuidados. Participaram dez mulheres, entre 65 e 89 anos, subdivididas em: institucionalizadas e não-institucionalizadas. Realizaram-se entrevistas semi-estruturadas, analisadas qualitativamente. Observou-se que o papel de “cuidadora” cria um vácuo na concepção dominante quando essas mulheres acedem à condição de objeto do cuidado do outro. Entretanto, parecem assumir um maior comprometimento com o autocuidado. Conclui-se que a família, programas comunitários e religião são as principais redes de suporte psicossocial. A ocupação e a sociabilidade influem na percepção do cuidado.

    Science.gov (United States)

    ACToR (Aggregated Computational Toxicology Resource) is a centralized database repository developed by the National Center for Computational Toxicology (NCCT) at the U.S. Environmental Protection Agency (EPA). Free and open source tools were used to compile toxicity data from over 1,950 public sources. ACToR contains chemical structure information and toxicological data for over 558,000 unique chemicals. The database primarily includes data from NCCT research programs, in vivo toxicity data from ToxRef, human exposure data from ExpoCast, high-throughput screening data from ToxCast and high quality chemical structure information from the EPA DSSTox program. The DSSTox database is a chemical structure inventory for the NCCT programs and currently has about 16,000 unique structures. Included are also data from PubChem, ChemSpider, USDA, FDA, NIH and several other public data sources. ACToR has been a resource to various international and national research groups. Most of our recent efforts on ACToR are focused on improving the structural identifiers and Physico-Chemical properties of the chemicals in the database. Organizing this huge collection of data and improving the chemical structure quality of the database has posed some major challenges. Workflows have been developed to process structures, calculate chemical properties and identify relationships between CAS numbers. The Structure processing workflow integrates web services (PubChem and NIH NCI Cactus) to d

    Full Text Available La experiencia y regulación de las emociones son aspectos que están adquiriendo mayor importancia a la hora de entender y fomentar el bienestar y la calidad de vida de las personas mayores. El objetivo del presente estudio ha sido llevar a cabo un estudio comparativo de la alexitimia en usuarios pertenecientes a un centro institucionalizado de personas mayores y alumnos matriculados en el aula de mayores. Los participantes del estudio fueron 43 personas institucionalizadas y 48 personas pertenecientes al aula de mayores con una media de edad de 69.30 años y una desviación típica de 66.50. El instrumento utilizado fue la versión adaptada del TAS-20. Los resultados mostraron que las personas institucionalizadas puntuaban más alto en la dificultad para identificar sentimientos, dificultad para describir sentimientos así como en el patrón de pensamiento orientado a lo externo. El sexo fue indiferente en la dificultad para identificar sentimientos, en la dificultad para describir sentimientos así como en el patrón orientado a lo externo. En cuanto a la edad, se encontró una relación con la dificultad para identificar sentimientos y el patrón de pensamiento orientado a lo externo. El estudio permite concluir que la alexitimia se ve influida por el hecho de que la persona mayor se encuentre en un centro institucionalizado.

  2. A violência institucionalizada pela indústria cultural: debates educativos

    Directory of Open Access Journals (Sweden)

    Adilson Cristiano Habowski

    2018-02-01

    Full Text Available As obras cinematográficas nos oferecem rica matéria-prima para novos entendimentos de mundo, de cultura e de linguagens que podem ser reconstruídos em diferentes contextos, bem como lançam questões sensíveis e ambíguas, que surgem como inquietações para aprender a pensar sobre a violência institucionalizada. Por meio de uma abordagem hermenêutica, interpretamos e compreendemos a série Game of Thrones como uma possibilidade de estabelecer um contraponto às complexas dinâmicas da violência física na arena social, pois há questões técnicas vinculadas ao mercado subjacentes ao filme que nos provocam reflexões sobre os problemas pungentes na vida contemporânea. A educação, nesse sentido, possui uma dimensão política de desafiar com a própria obra cinematográfica os padrões instituídos, viabilizando novos debates à reeducação dos modos de agir massificados e violentos, a fim de respeitar e valorizar as diferenças socioculturais. Somente por um caminho de infindável reconciliação com o outro em suas diferenças e conflitos sociais poderemos superar o sentimento individualista diante da violência e das permanentes relações controversas e conflitos que nos assolam. Os resultados indicam que é preciso levar em consideração a forma institucionalizada em que a educação se concretiza como apropriação de conhecimentos da indústria cultural, para superar as obviedades e banalidades do mundo e instaurar diálogos educativos menos opressores, apassivadores e conformistas, articulando projetos sociais contra a reincidência ou perpetuação das violências comercializadas e outros tipos de barbárie na escola.

    La relación médico-paciente, esencia del ejercicio de la Medicina, se produce cada vez que un profesional a quien la estructura social y jurídica de un país ha catalogado como idóneo para ejercer la Medicina, acepta la petición de otro miembro de la sociedad que acude en búsqueda de su opinión, consejo y posible tratamiento.

    Como lo expresa la Ley 23 de 1981 (Titulo 1, Capítulo 1, Artículo 4:

    “La relación médico-paciente es elemento primordial en la práctica médica. Para que dicha relación tenga pleno éxito, debe fundarse en un compromiso responsable, leal y auténtico…”

    De acuerdo con dicha ley, la relación médico-paciente se cumple en los siguientes casos:

    1. Por decisión voluntaria y espontánea de ambas partes.
    2. Por acción unilateral del médico, en caso de emergencia
    3. Por solicitud de terceras personas
    4. Por haber adquirido el compromiso de atender a personas que están a cargo de una entidad privada o publica”

    Título 11, Capítulo 1, Artículo 5. Ley 23 de 1981

    ¿Qué es el acto médico?
    El acto médico, en el cual se concreta la relación médico-paciente, es una forma especial de relación entre personas; por lo general una de ellas, el enfermo, acude motivada por una alteración en su salud a otra, el médico, quien está en capacidad de orientar y sanar, de acuerdo a sus capacidades y al tipo de enfermedad que el primero presente.

    A través del acto médico se intenta promover la salud, curar y prevenir la enfermedad y rehabilitar al paciente.

    El médico se compromete a colocar todos los medios a su alcance para efectuar un procedimiento (médico o quirúrgico, actuando con apoyo en sus conocimientos, su adiestramiento técnico y su diligencia y cuidado personal para curar o aliviar los efectos de la enfermedad, sin poder garantizar los resultados, previa advertencia de los posibles riesgos y complicaciones

    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.

    Full Text Available Como contrapeso a una visión cada vez más objetiva de la disciplina contractual, el análisis de la noción de contrato como acto de previsión permite confirmar el papel de primacía de la autonomía de la voluntad. Tomada la previsión en el momento de ser concebida por las partes, su análisis permite, de acuerdo con la naturaleza del contrato, reforzar la distinción entre efecto el del contrato y el efecto de la obligación y, al mismo tiempo, comprender la dicotomía –existente o aparente– entre formación y ejecución del contrato y ejecución e incumplimiento del mismo, así como de su incidencia en la concepción misma de la responsabilidad contractual, al servir como instrumento en la determinación de la noción de fuerza obligatoria del contrato. De igual forma, haciendo una proyección hacia el futuro para determinar la suerte de las previsiones contractuales, la explotación de su concepto permite depurar la noción y utilidad de la teoría de la imprevisión, que en el Derecho Civil francés no ha encontrado aún asidero y cuyo papel ha sido sustituido sea por la doctrina, sea por la jurisprudencia, haciendo uso del principio de buena fe y de la teoría de la causa, aunque de forma parcial y no de manera indiscutida.

    Full Text Available Las opiniones que aparecen en la página web TripAdvisor, como muestra relevante de la promoción del Turismo 2.0, se convierten, dadas las características de este discurso, en macroactos de habla directivos en los que convergen actos de distinta naturaleza. Si bien se presentan como opiniones, trascienden los límites de la mera información para convertirse en actos directivos, ya que el opinante se ve implicado en la construcción de una especie de guía de ayuda a otros viajeros. Por tanto, el objetivo de este trabajo es categorizar los distintos tipos de las denominadas por la página web TripAdvisor “opiniones” como sugerencias, consejos, recomendaciones y advertencias, y analizar las estrategias de atenuación a las que se recurre en su formulación al servicio de distintas actividades de imagen. Los resultados muestran una tendencia que nos lleva a proponer la distinción entre estos tipos de actos directivos sobre la base de: la recurrencia a estrategias de atenuación, factores como el poder o la voluntad del opinante, el coste-beneficio para el destinatario, así como las propias calificaciones de las opiniones – en las categorías “excelente”, “muy bueno”, “normal”, “malo” y “pésimo”– establecidas por la propia página web. Tener en cuenta todas estas variables nos ha permitido constatar la existencia de un continuo de los actos de habla que se corresponden con diferentes grados de estrategias de atenuación, también en función de las categorías de evaluación y de los mecanismos utilizados para producir el acto.

    Full Text Available La cultura de origen influye de manera determinante no solo en el universo cognitivo de los hablantes, sino también en los patrones comunicativos que se ponen en juego en las interacciones cara a cara. Uno de estos patrones es la tendencia a resolver las situaciones mediante actos de habla directos o indirectos, el cual depende, además, del grado de confianza que exista entre los interlocutores. Las actividades propuestas tienen como objetivo evitar los malentendidos que surgen en estas circunstancias y fomentar el éxito comunicativo, motivo por el cual han sido diseñadas para desarrollar los cuatro aspectos que intervienen en esta interacción: las estrategias interculturales de las que dispone el alumno; la variabilidad del patrón comunicativo en función de las culturas de origen; los recursos formales lingüísticos y la comunicación no verbal.

Para ello, en una primera parte se muestra un estado de la cuestión acerca del concepto de acto de habla y del análisis de manuales de ELE. En la segunda parte, se estudian diez manuales diferentes de enseñanza de español, correspondientes a los niveles A1 y A2, atendiendo en esencia a cinco actos de habla representativos de sendos grupos, tal y como se definen en las teorías pragmáticas clásicas: la descripción de objetos como acto de habla asertivo o representativo; el consejo como acto de habla directivo; la expresión de la certeza y la evidencia como acto compromisivo; la felicitación como acto de habla expresivo y la presentación como representante de los actos de habla declarativos. Las principales conclusiones apuntan a que ninguno de los manuales analizados permite un aprendizaje adecuado de todos los actos de habla, si bien hay secuencias didácticas realmente aceptables para trabajar alguno de ellos, que pueden contribuir a que el profesor de idiomas lleve con éxito al aula aspectos esenciales de la pragmática del español.

En el presente artículo pretendemos describir y analizar la composición arquitectónica de los actos escolares como formato semiótico-comunicativo.

    Full Text Available Consideradas verdadeiras masmorras medievais, as prisões têm servido para depósito de seres humanos que vivem em degradantes condições, violadoras de direitos fundamentais, que vão além da pena imposta pelos delitos cometidos. O problema da caótica situação carcerária brasileira é impulsionado diariamente pelo aprisionamento em massa e pelo controle social decorrente da política pública de repressão às drogas ilícitas. Cotejando o marco teórico da criminologia crítica com os dirietos fundamentais positivados na Constituição Federal de 1988, em seu núcleo dignidade humana, e empregando o método dedutivo, o estudo tem por objetivo evidenciar a institucionalizada violação de direitos fundamentais pela política pública carcerária, por meio de um controle social incidente de modo seletivo sobre os indivíduos pertencentes às classes desfavorecidas ou vulneráveis. A conclusão da pesquisa é a de que não há como negar a omissão do Estado e a conivência das instituições públicas fiscalizadoras na situação que envolve o sistema carcerário, ante a revelação de violação de direitos fundamentais, como tortura, fome, maus-tratos, superlotação, abusos sexuais, morte, entre outros, como forma de controle social das classes vulneráveis.

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.

    Full Text Available Las cooperativas son personas jurídicas que pueden realizar contratos, comparecer en juicio y actuar en todo aquello que esté conforme con su índole social y económica. Sus actos son de comercio en la forma, pero no en la esencia, por no existir el lucro, por no reunir todas sus características formales. Se distinguen entre actos internos y externos. Los primeros son los celebrados entre los asociados y la cooperativa; los segundos, los celebrados con terceros no asociados, pero para beneficio de sus asociados, o mejor dicho, para poder cumplir el fin social. Lo que se pretende en reconocer el espíritu del cooperativismo, lo que conduce al punto central de este trabajo: “El acto cooperativo” desde la perspectiva de su reglamentación. Las organizaciones de la economía solidaria, han sido creadas, como su nombre lo indica, con el espíritu de protección hacia los más necesitados, ofreciendo servicios de mayor acceso a las poblaciones más vulnerables; pero esto se ha desvirtuado por estas entidades al aprobar créditos desconociendo algunos de los derechos y a su vez excediendo los límites de sus actuaciones, al usar las prerrogativas otorgadas por la ley y realizar embargo de pensiones y salarios de personas que no son asociados o que no ejercen sus derechos como tal, lo que constatamos con el mayor número de quejas que presentan los usuarios en la Superintendencia de la Economía Solidaria por el tema de Usura y otras irregularidades en el otorgamiento y cobro de créditos. Se sugiere entonces la reglamentación del acto cooperativo dentro de nuestra legislación colombiana a través de una Ley, Decreto o norma imperativa que le de fuerza o herramientas a los colombianos y a las entidades de control para actuar en contra de los administradores o entidades solidarias que cometen este tipo de actuaciones contrarias a derecho.

Cytosol has been treated as a low viscosity Newtonian fluid flowing through the high viscosity porous medium of F-actin network. Other involved phenomena including myosin activity, adhesion friction, and interphase interaction are also discussed to provide an overall view of this problem. Adopting a two-phase coupled model by myosin concentration, we have found new accurate perspectives of acto-cytosolic flow and pressure fields, myosin distribution, as well as the distribution of effective forces across the lamellipodia of a keratocyte with stationary shape. The order of magnitude method is also used to determine the contribution of forces in the internal dynamics of lamellipodia.

    Full Text Available Los actos de violencia armada tienen la capacidad de resignificar los espacios alrededor de los cuales una comunidad ha construido su identidad social. En el pequeño poblado palafito de Nueva Venecia (Magdalena-Colombia, tres distintos actores armados (la guerrilla, los paramilitares de extrema derecha y la fuerza pública colombiana convocaron a la población, en tres distintos momentos, en el mismo espacio social: la plaza principal del pueblo. En la primera reunión, el primer grupo advirtió sobre la posibilidad de una masacre; en la segunda, los pobladores fueron víctimas y testigos de la forma en que el segundo grupo la ejecutaba; y en la tercera reunión, el tercer grupo ofrecía excusas por lo sucedido. El artículo analiza la forma en que estos tres actos determinaron tres marcas del continuum de la violencia sobre ese espacio nodal de memoria. El texto está organizado narrativamente alrededor del último de estos actos, cuando representantes del ejército y la policía colombianas ofician una ceremonia pública de perdón por la masacre paramilitar. El análisis de dicha ceremonia la revela más como un escenario donde los agentes de memorias enfrentadas despliegan dispositivos discursivos para legitimarse socialmente como un verdadero acto de reparación simbólica.

    Full Text Available El presente artículo caracteriza las fórmulas nominales de tratamiento ( FNT en el habla de Medellín y toma en cuenta los aspectos pragmáticos que intervienen en la selección de estas en el marco de actos de habla descorteses. Para esto, se ha empleado una metodología sociopragmática, a partir de la cual se propone una serie de criterios metodológicos que explican cómo fue realizado el proceso de recolección de la información, así como los procesos de sistematización y de análisis pragmático de las fnt . Se resalta en este artículo que la relación entre fnt y actos descorteses se establece por el hecho de que estas desempeñan una función de refuerzo del acto descortés. Se pudo establecer que, en el marco de los actos descorteses, el uso de una fnt de trato íntimo o de solidaridad no logra el mismo efecto de atenuación que podría producir ante enunciados no corteses.

    Full Text Available Repensar las instituciones, las prácticas y los discursos referentes a la infancia y a quienes operan en ella dentro del sistema judicial, implica un proceso de construcción- deconstrucción permanente. Revisar las variables socio-históricas respecto de la infancia institucionalizada, significa trabajar en pos de los postulados de la Convención Internacional de los Derechos del Niño, reparando en el complejo entramado que legitima la intervención sobre los niños. Esto implica recorrer un camino que va de la concepción de la infancia como objeto a otra como sujeto. El posicionamiento dentro de uno u otro de estos paradigmas, conlleva diversos niveles de sufrimiento para la infancia, los profesionales y las instituciones. Se intenta describir la práctica de la psicología jurídica con la infancia institucionalizada, en tanto práctica organizada bajo la fantasía de salvar a un niño.To rethink the referring institutions, practices and discourses to the childhood and to those who operate in her within the judicial system, implies a process of permanent construction-deconstruction. To review the socio-historical variables respect to the institutionalized childhood means to work after the postulates of the International Convention of the Child's Rights, repairing in the half-framed complex that legitimizes the intervention on the children. This implies to cross a way that goes of the conception of the childhood like object to another one like subject. The positioning within one or another one of these paradigms, entail diverse levels of suffering for the childhood, the professionals and the institutions. This paper tries to describe the practice of the legal psychology with the institutionalized childhood, in as much practical organized under the fantasy to save a child.

    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.

    Full Text Available OBJETIVO: Descrever a dinâmica alimentar de idosas institucionalizadas no que se refere aos aspectos clínicos de deglutição, cognitivos, comportamentais e ambientais ligados à alimentação. MÉTODOS: Realizou-se um estudo observacional transversal prospectivo, que descreveu a dinâmica de alimentação de 30 idosas residentes numa instituição de longa permanência. Alguns dos aspectos analisados foram registrados por observadores no momento da alimentação e outros em filmagem da refeição de cada idosa. Os dados foram apresentados de forma descritiva e comparados à literatura. RESULTADOS: A média de idade foi 83,7 anos. Os diagnósticos médicos mais prevalentes foram síndrome demencial e hipertensão arterial sistêmica. Foram observados: ingestão oral pobre em 73,3% das idosas, tempo médio de alimentação de 10,1 minutos, posicionamento inadequado em 46,7% das refeições, alterações atitudinais em 16,7% e comportamentais em 40% das idosas. A assistência foi requerida por 56,6% das idosas, tendo sido provida a 70,6% desses casos, e julgada inadequada em 66,6% deles. Eram edêntulas 44,4% das idosas, das quais 46,1% utilizavam prótese dentária total, sendo predominante a inadequação da adaptação, do estado de conservação e da higiene (83,4%. A prevalência de alterações de deglutição foi igual a 23,3%, sendo as mais prevalentes os resíduos alimentares após a deglutição, tosse durante a alimentação e alteração vocal após a deglutição. CONCLUSÃO: Verificou-se presença significativa de fatores ambientais, cognitivos e comportamentais ligados à alimentação que podem oferecer risco à deglutição. Também se identificaram outras alterações específicas da deglutição, cujo gerenciamento é importante para evitar complicações da saúde destas idosas.PURPOSE: To describe the feeding dynamics of institutionalized elderly women regarding the clinical aspects of deglutition, cognition, behavioral and

  12. Two-boundary first exit time of Gauss-Markov processes for stochastic modeling of acto-myosin dynamics.

    Science.gov (United States)

    D'Onofrio, Giuseppe; Pirozzi, Enrica

    2017-05-01

    We consider a stochastic differential equation in a strip, with coefficients suitably chosen to describe the acto-myosin interaction subject to time-varying forces. By simulating trajectories of the stochastic dynamics via an Euler discretization-based algorithm, we fit experimental data and determine the values of involved parameters. The steps of the myosin are represented by the exit events from the strip. Motivated by these results, we propose a specific stochastic model based on the corresponding time-inhomogeneous Gauss-Markov and diffusion process evolving between two absorbing boundaries. We specify the mean and covariance functions of the stochastic modeling process taking into account time-dependent forces including the effect of an external load. We accurately determine the probability density function (pdf) of the first exit time (FET) from the strip by solving a system of two non singular second-type Volterra integral equations via a numerical quadrature. We provide numerical estimations of the mean of FET as approximations of the dwell-time of the proteins dynamics. The percentage of backward steps is given in agreement to experimental data. Numerical and simulation results are compared and discussed.

Estos actos tienen elementos no regrados en el sistema legal, que dependen de la sentencia de la conveniencia y oportunidad del administrador público. Estos elementos se llaman méritos del acto administrativo. Antes, guardián de la libertad completa, ya que no se rige por la ley, que actualmente sufre más restricciones, la necesidad de respetar los principios del derecho, especialmente los que figuran en la Constitución, en el artículo 37. En consecuencia, aumenta la posibilidad de control judicial. El poder judicial tendrá un Consejo de control de la legalidad en su conjunto, incluyendo el mérito administrativo, si es provocado correctamente por el legítimo y respetando los límites impuestos por la propia Constitución.

Los marcadores de fuerza ilocutiva se forman a partir de operaciones metalingüísticas, lo que tiene relación con la teoría de la relevancia en tanto éstos pueden restringir las interpretaciones posibles del enunciado. Sin embargo, considerar que el oyente aprehende los enunciados como declarativos verificables es minimizar el hecho de que los actos de habla son aprehendidos como acciones.

Así, los actos de habla pueden considerarse como operaciones viables en un determinado dominio discursivo.

    Full Text Available Se considera que una de las condiciones que más vulnera, fragiliza y rompe el equilibrio psíquico de un sujeto es el sometimiento a experiencias violentas. En particular, aquellas en las cuales tenga pocas opciones de realizar acciones para detener o evitar el accionar de los violentos y librarse de esa posición de pasividad. De allí surgieron las preguntas que orientaron esta investigación respecto a las diferentes posiciones del sujeto para explicar el acto de desplazarse y su anudamiento con las experiencias violentas que obraron en calidad de traumas.

    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...

    2006-02-01

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

    2017-01-01

    Full Text Available En este artículo desarrollamos el concepto de lenguaje y de cómo él, como acción del hombre en el hombre, al hacerse presente a modo de representación y expresión, tiene la pretensión de validar aquello que conoce –el objeto– y la manera como lo conoce. De esta forma, partimos de concebir el lenguaje como un sistema, una semiótica social y una intención. Mediante el lenguaje y el acto comunicativo de la interlocución, el sujeto determina la veracidad/validez del hecho, la acción: actúa en el sistema y acorde con él, y establece el nivel de correspondencia de la idea –pensada o manifestada– y el objeto, como producto final de su capacidad de hacer y comunicar. Como tesis, planteamos que, independientemente del modo o modos en que se conjuguen los códigos lingüísticos, lo que importa es su posibilidad de veracidad. De igual modo, esos niveles y posibilidades están limitados o ampliados por los sistemas-mundo de los sujetos intervinientes en el acto de habla.

    2011-12-01

    Full Text Available Las decisiones administrativas deben sujetarse al interés público no solo al momento de su aprobación sino durante su vigencia, por lo que se hace necesaria una institución como la revocación. Sin embargo, la existencia de la potestad revocatoria de actos administrativos conduce a la afectación de la seguridad jurídica, debido al efecto expropiatorio que tiene sobre derechos y situaciones jurídicas, con lo que se torna necesaria la búsqueda de fórmulas conciliadoras. En tal contexto, el presente artículo, además de brindar importantes alcances conceptuales, busca identificar los requisitos para la revocación del acto administrativo, ahondar en su estructura operativa, distinguir las clases de revocación existentes y señalar sus diferencias con otras figuras, como la nulidad, la caducidad, entre otras.

    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.

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

    Full Text Available En su polémica obra de 1995, The construction of social reality, John Searle presentaba una “nueva ontología de la realidad social” que, a menudo, utilizaba el dinero como ejemplo de sus análisis constitutivos. Uno de los aspectos que alguna crítica losó ca desarrolló con más intensidad respecto a las tesis de Searle en aquel libro era la posibilidad (que Searle negaba de que existieran objetos sociales independientes de base material (free – standing Y terms. Después de diversos artículos polémicos al respecto, Searle presentó, en el año 2010, una revisión y reexposición de sus concepciones al respecto (Making the social world, en la cual creía poder superar los elementos críticos de su anterior exposición (principalmente vinculados a algunos malentendidos respecto al alcance de la fórmula constitutiva “X cuenta como Y en C” postulando el principio según el cual “todos los hechos institucionales, y por consiguiente todas las funciones de status, son creadas por actos de habla del tipo de las “declaraciones””. El ob- jetivo del presente artículo consiste en mostrar que la reexposición de la teoría de Searle no permite llevar a cabo ningún avance en el terreno de la ontología del dinero siempre que no se modi que sustancialmente su concepción sobre la génesis del dinero, que hace surgir el dinero como objeto social a partir de la función de medio de cambio. Sin una revisión profunda del “relato genético” sobre el dinero que Searle mantenía en 1995 (muy próximo a lo que se puede considerar “análisis ortodoxo” en teoría monetaria, la nueva presentación del dinero como acto de habla aparece llena de tensiones entre el nivel constitutivo y el nivel genético, de manera que las potencialidades de una teoría del dinero como acto de habla se desvanecen.

    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.

    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.

    2015-01-01

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

  16. Análisis filosófico y teológico de la mentira desde la teoría de los actos de habla

    2016-06-01

    Full Text Available En el panorama filosófico actual nos encontramos con diferentes teorías semánticas de la verdad. Por su parte, la mayoría de los autores de teología moral siguen de cerca el pensamiento de San Agustín y de Santo Tomás de Aquino, definiendo la mentira como un lenguaje contrario al propio pensamiento con la voluntad de engañar. Es preciso integrar en el análisis filosófico y teológico de la mentira la teoría de los actos de habla (Austin, Searle y Habermas, entre otros, ya que el mentir no se reduce a su dimensión locucionaria. Presenta, además, una fuerza ilocucionaria y una intención comunicativa, desde la que pueden reinterpretarse los principios clásicos de la anfibolia o restricción mental, las respuestas con doble sentido, el mal menor o las mentiras piadosas. Así pues, la noción filosófica y teológica de mentira debe tener en cuenta los análisis provenientes de las ciencias humanas y, especialmente, de las ciencias lingüísticas. Además, se debe recordar que no siempre es posible ni deseable para los seres humanos expresar una perfecta adecuación entre lo que el individuo dice que es verdad, lo que cree que es verdad y lo que la realidad es en sí. Por ello, además de la dimensión locucionaria, es preciso incorporar en el análisis del acto de habla del mentir las dimensiones de la coherencia, de la autenticidad, de la fidelidad, de la honestidad y trasparencia, asumiendo al mismo tiempo la opacidad, las paradojas de la vida y la ironía de la existencia humana.

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

    LLNL has an ongoing research and development project that includes developing data acquisition systems with remote wireless communication for monitoring the vibrations of large civil engineering structures. In order to establish the capability of performing remote sensing over an extended period of time, the researchers needed to apply this technology to a real structure. The construction of the National Ignition Facility provided an opportunity to test the data acquisition system on a large structure to monitor whether the facility is remaining within the strict ambient vibration guidelines. This document will briefly discuss the NIF ambient vibration requirements and summarize the vibration measurements performed during the Spring and Summer of 1999. In addition, a brief description of the sensors and the data acquisition systems will be provided in Appendix B

  8. Types for BioAmbients

    2010-02-01

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

Nos proponemos indagar qué recursos los interlocutores, universitarios en encuentros orales con fines de estudio, utilizan en la actividad de imagen en actos asertivos. Para tanto, presentamos aquí una propuesta metodológica que pretende delinear el trasfondo de las construcciones discursivas. El corpus de este estudio se compone de veinticinco horas de videograbaciones y ochenta test de hábitos sociales (Hernández Flores, 2002; Contreras, 2004 y Bernal, 2007. En un análisis sincrónico, identificamos en el contexto brasileño, la tendencia del individuo a proyectar la imagen de cordialidad, cooperación y semejanza en la gestión de la autoimagen. Entre los interlocutores chilenos, la imagen de orden y la imagen de jerarquía fueron las que se evidenciaron. Destacamos contrastes, además de semejanzas, entre algunas estrategias pragmáticas, en relación con el fenómeno de la atenuación asertiva e intensificación, mecanismos de autorrepetición y alorrepetición. Los resultados, que encontraron eco en estudios de otras ciencias del comportamiento humano, en el análisis del corpus y en las respuestas de los informantes al test de hábitos sociales, pueden facilitar la proyección de experiencias específicas de un corpus a un estilo de cortesía que se extienda a otras situaciones de comunicación sin prescindir de la enorme diversidad del uso del lenguaje (Bravo, 2004a.

Como se sabe, el tratado en mención creó la interpretación prejudicial, que consiste en la posibilidad que tienen los jueces de los países miembros de la Comunidad Andina de Naciones (CAN de consultar al TJCA, acerca de la interpretación de una norma comunitaria, en el supuesto de que dichos jueces se encuentren resolviendo un caso en el cual deban aplicar disposiciones jurídicas de la CAN, o al menos las partes discutan dicha aplicación. Los jueces nacionales están obligados a realizar la referida consulta en todas las hipótesis en las que la sentencia que dicten no sea susceptible de recurso, según el derecho interno correspondiente. En el resto de los asuntos tal consulta es facultativa de los jueces internos. En este marco, el trabajo trata sobre si, en el supuesto de que la consulta del juez nacional al TJCA sea obligatoria, tal imperatividad debería ceder cuando el propio Tribunal ha resuelto la cuestión reiteradamente, a través de una IP previa, en un asunto que guarda analogía de hecho y de derecho.

    Full Text Available La realidad socioeducativa actual demanda de los profesionales de la educación una intervención comprometida y coherente para el desarrollo de competencias y habilidades emocionales. Es necesario complementar lo académico y cuantificable con aquello que sobrepasa las barreras del centro e influye en el rendimiento y desarrollo personal y social del alumnado. Las relaciones que se dan entre los componentes de la triada emoción, pensamiento y acción regulan cada momento de nuestros días, pudiéndose ver estas alteradas negativamente por estímulos externos que en ocasiones, no somos capaces de gestionar adecuadamente. Esta incorrecta gestión emocional tiene su base en un creciente analfabetismo emocional que nos lleva a respuestas impulsivas y no reflexivas. Este artículo plantea una propuesta de intervención en el aula de Educación Primaria que tiene como base el diálogo y la cooperación para el desarrollo de competencias-­‐habilidades emocionales desde el acto comunicativo-­‐dramático, enfatizando en los beneficios que esta herramienta pedagógica tiene para con el desarrollo de espacios inclusivos donde los estudiantes puedan expresarse libremente. Esta propuesta tiene un carácter abierto y su concreción vendrá determinada por el contexto y la implementación en las aulas. El trabajo concluye planteando la conveniencia de la puesta en práctica de Programas de Educación Emocional.

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.

    2009-08-01

    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

    Full Text Available En el contexto de símbolos, valores, actitudes y comportamientos de orden tradicional, la construcción de la república de Venezuela requiere legitimar una nueva simbología institucional y política. El presente trabajo analiza y busca generar nuevas aportaciones que ayuden a comprender en el nacimiento de la nueva identidad “republicana” durante las primeras décadas del siglo XIX. El objetivo es destacar los dispositivos discursivos que explican tal construcción a partir de algunas ceremonias, actos públicos, fiestas, canciones que ponen en escena símbolos y signos que aunque en el contexto de corte antiguo “legitimadores de la monarquía y sus prácticas,” buscan durante toda la coyuntura independentista imponerse y hacerse necesarios con el propósito de asegurar los principios que consoliden efectivamente la estabilidad de la nueva república. Para el análisis de los alcance y límites de la nueva simbología republicana, ha sido fundamental la aplicación del método histórico, es decir, partiendo de unas problemáticas se procedió a la localización, arqueo y revisión de diversidad de fuentes,siendo las principales las del Archivo General de Indias, para comprobar la factibilidad y utilidad de las mismas en el abordaje de la investigación y lograr contrastar la información obtenida con el problema propuesto y así dar cuenta de la realidad objeto de estudio;dichas fuentes son un valioso aporte que permite no solo comprender sino articular el estudio con otras investigaciones relacionadas con las prácticas y comportamientos de las sociedades pertenecientes al régimen monárquico Español y que prácticas y dispositivos simbólicos son los que las nacientes repúblicas sobre todo en nuestra América Latina se apropian e incluyen como parte de esa realidad material y simbólica que explica la construcción de las repúblicas siendo nuestro caso el de Venezuela.

    Full Text Available La finalidad del trabajo es aportar información y propuestas conceptuales que faciliten la tarea de quienes tienen a su cargo la sistematización institucional de la salud ambiental. Se hace un análisis de la noción de "ambiente" para la cual se sugiere una definición, y se examina el lugar de la salud ambiental en el contexto de los problemas ambientales y sus vertientes "verde" y "azul". Se examinan denominaciones equivalentes de salud ambiental y se introducen los servicios de salud ambiental. Se proporcionan varias definiciones y se da la oficial de salud ambiental adoptada por la OMS en Sofía, Bulgaria (1993. A continuación se transcriben las áreas básicas que a la salud ambiental le han asignado diversas organizaciones o reuniones, como la OPS, la OMS, el Programa 21 y otros. A partir de aquí se construye un repertorio bastante completo de áreas y subáreas y se encuentra que todos los listados son, en realidad, una reunión asistemática de tres tipos de constituyentes: determinantes (factores o hechos de la realidad física, procesos (conjuntos de intervenciones y funciones (conjuntos de acciones de gestión, los cuales pueden enfocarse matricialmente y llevan a individualizar actividades de los servicios de salud ambiental. Se proponen unas reglas de operación que permiten, en una especie de álgebra, construir expresiones para especificar con precisión las actividades y sus agregados. De este modo se logra disponer de un lenguaje simbólico común que puede ayudar a la intercomunicación, enseñanza e investigación en el ámbito de la salud ambiental.

    Full Text Available Los precipitadores situacionales del delito (Wortley, 2008 han recibido poca atención por la literatura criminológica en lengua española, y con frecuencia son subsumidos dentro de la perspectiva de la elección racional (Cornish & Clarke, 2003. 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.

    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. In this sense, it can not be oblivious to the reviews and its existence is only possible in the various reactions that occur in the subject

    Antoniadis, Ignatios; Cotsakis, Spiros

    2015-01-01

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

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

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

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

    Full Text Available En el contexto de los procesos de liberalización y los nuevos regímenes económicos a nivel constitucional, la regulación económica se posicionó como una de las principales actividades de intervención estatal sobre la economía. Esta se concibe como un instrumento técnico, neutral e independiente, diseñado para resolver las fallas del mercado y armonizar objetivos económicos y no económicos, generalmente contrapuestos. Por tanto, la cabida del control judicial es muy cuestionada, evidenciándose choques entre la garantía de acceso a la justicia de los particulares y la competencia técnica de los reguladores. Así, se efectúa un análisis material de los actos proferidos por las autoridades de regulación en clave de la extensión del principio de legalidad, y basado en las funciones asignadas a la CRC según la Ley 1341 de 2009, con el propósito de determinar los marcos, límites y alcances del control judicial.

    2015-05-01

    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.

Con base en este argumento, se examinan cinco definiciones de la situación de los menores desvinculados de los grupos armados ilegales en Colombia, denominadas de acuerdo con sus efectos psicoeducativos: victimizante, patologizante, criminalizante, idealizante y responsabilizante. Cada definición se examina en función de su filiación filosófica, determinista, indeterminista o interaccionista; en sus efectos en la construcción de la identidad de los menores y en su apelación a la imputabilidad o inimputabilidad jurídica. Al final del artículo, se muestran las propuestas de intervención que se derivan de cada una de las definiciones y se muestra el papel que puede jugar la justicia restaurativa en la construcción de un modelo de atención responsabilizante para los menores desvinculados de los grupos armados ilegales, y otras víctimas del conflicto armado, que les garantice la restitución de los derechos y a la vez los empodere como actores protagónicos en la redefinición de su rol social y la reconstrucción de su identidad.

  11. Ambient temperature signalling in plants.

    Science.gov (United States)

    Wigge, Philip A

    2013-10-01

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

Chegamos a "era da revolução ambiental", e o ambiente não somente aparece como um conjunto de problemas relativos ao controle da contaminação, mas representa um custo no crescimento econômico. Neste sentido, o contador precisa de uma formação que se estenda além dos limites das técnicas e dos procedimentos.

    Full Text Available O presente artigo analisa e confirma a existência de impactos ocasionados pelos conflitos em um ambiente organizacional, através de pesquisa de campo realizada a partir de um estudo de caso e a comparação com a literatura adotada. A empresa escolhida foi abordada a partir de questionários, que foram respondidos pelos colaboradores e também pelo gestor. Percebeu-se que esses impactos são complexos de mensurar, principalmente os financeiros, que normalmente ficam ocultos por muito tempo. Entretanto, não se pode negar sua existência, pois estes tendem à piorar quando não são considerados.  Foi observado com a pesquisa que a conduta adotada para intermediar os conflitos está diretamente ligada ao sucesso de impedir impactos negativos aos indivíduos e à organização como um todo. Essas condutas, quando bem aplicadas podem contribuir reverter o impacto de um conflito, fazendo com que ele seja um fator motivador de mudanças e um estímulo para que os indivíduos demonstrem seus potenciais.

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

    Full Text Available 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 Foram analisadas representações sociais sobre alimentação entre moradores de instituições de longa permanência para idosos, para identificar condicionantes do comportamento alimentar que podem interferir no estado nutricional destes indivíduos. 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.

Participaram três crianças abrigadas em idade pré-escolar, sendo um menino e duas meninas. As sessões de brinquedo terapêutico do tipo dramático foram realizadas em um local reservado, variando de trinta a cinquenta minutos, com a seguinte proposta norteadora: "Vamos brincar de uma criança que mora no abrigo?" Foi possível apreender duas amplas categorias temáticas: o brincar e o faz de conta e o brincar e a realidade. Ao brincar de faz de conta, ora de modo tranquilo, ora de modo violento, as crianças trouxeram conteúdos que evidenciaram situações de seu cotidiano familiar. Ao exporem sua realidade, as crianças abordaram questões sobre a instituição de abrigamento e a vinculação com estes profissionais e com os familiares. É possível afirmar que o brinquedo terapêutico permitiu uma comunicação eficaz da criança por meio da expressão de seus sentimentos, de seus desejos, de suas experiências vividas, de críticas ao meio onde vive e às relações familiares, além de possibilitar um momento de prazer e de descontração.This qualitative research is based on the reference framework of Phenomenology analysis of the structure of the situated phenomenon, and aims to understand institutionalized children victims of violence through therapeutic play sessions.

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

    Robertson, Sarah; Miller, Mark R

    2018-01-03

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

    Directory of Open Access Journals (Sweden)

    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.

  5. The Aesthetics of the Ambient Video Experience

    Directory of Open Access Journals (Sweden)

    Jim Bizzocchi

    2008-01-01

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

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

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

Dentro desta área, deve-se ressaltar que a responsabilidade civil ao meio ambiente, é um assunto de importante relevância para o efetivo controle da depredação ambiental, permitindo que sejam alcançadas as metas propostas como condição de sobrevivência da espécie humana, ou seja, a conservação do meio ambiente e o desenvolvimento econômico social, visando desta maneira, permitir a qualidade e a continuação da vida. Existe o entendimento, que somente com educação ambiental e normas reguladoras fortes, como a penalidade de ter que indenizar quando praticar algum dano ao meio ambiente conseguirá atingir o objetivo maior de preservação. Necessitam-se além de uma mudança na legislação que responsabilize poluidores do meio ambiente, atribuindo-lhes sanções que inibam a prática de tal conduta ilícita e realizando assim, a aplicabilidade da justiça.Palavras-chave:Responsabilidade Civil; Responsabilidade; Meio Ambiente ABSTRACTThis article have objective to realize a analysis about civil responsibility evolution and your theories, subjective and objective apply environment.

    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.

    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

  8. Setting priorities for ambient air quality objectives

    International Nuclear Information System (INIS)

    2004-10-01

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

  19. Automated Processing Workflow for Ambient Seismic Recordings

    Girard, A. J.; Shragge, J.

    2017-12-01

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

  5. Densification of silica glass at ambient pressure

    2006-01-01

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

    2012-01-01

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

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

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

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

  2. Towards full waveform ambient noise inversion

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

    2015-01-01

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

  15. Ambient Noise in an Urbanized Tidal Channel

    Science.gov (United States)

    Bassett, Christopher

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

    2014-01-01

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

    2018-04-01

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

This paper presents a novel design, implementation and assessment of a Smart Kitchen which provides Ambient Assisted Living services; a smart environment that increases elderly and disabled people's autonomy in their kitchen-related activities through context and user awareness, appropriate user interaction and artificial intelligence. It is based on a modular architecture which integrates a wide variety of home technology (household appliances, sensors, user interfaces, etc.) and associated communication standards and media (power line, radio frequency, infrared and cabled). Its software architecture is based on the Open Services Gateway initiative (OSGi), which allows building a complex system composed of small modules, each one providing the specific functionalities required, and can be easily scaled to meet our needs. The system has been evaluated by a large number of real users (63) and carers (31) in two living labs in Spain and UK. Results show a large potential of system functionalities combined with good usability and physical, sensory and cognitive accessibility. PMID:24445412

    Partiendo del principio que señala que para tener una visión más clara de un fenómeno social particular se requiere ubicarlo dentro de una perspectiva histórica, global, sistémica y compararlo con otros semejantes, he resuelto hacer una aproximación a la relación a la guerra en Colombia con un enfoque histórico, antropológico y bioético.

    La guerra, además de mirarse dentro de los términos militares clásicos como “la política por otros medios”, ella debe entenderse en los de la salud pública y ecológicos como “el peor desastre antrópico” y la “mayor de las emergencias complejas” y en los de los derechos humanos que la ven como la “negación de la paz”.

    Nuestra guerra actual es parte de nuestro historial de guerras. Las guerras ínter tribales prehispánicas libradas sin armas de metal y de fuego, sin claras ideas sobre vanguardias, retaguardias, tácticas militares, de líneas de apoyo logístico, etc., se desarrollaron en una época de aislamiento de América de los grandes focos de enfermedades infecciosas del Viejo Mundo.

    La llamada Conquista española se puede entender como una guerra de tierra arrasada, en donde los europeos utilizaron la tea incendiaria, los mastines, el caballo, las armas de metal y fuego, y los sistemas de guerrear propios de ejércitos curtidos en luchas contra otros ejércitos con el fin claro de sojuzgar a los nativos e imponerles una lengua y una religión nuevas, mientras las sociedades nativas ante semejante embate de ambición material y desprecio humano huían, abandonaban sus cultivos, luchaban o se suicidaban, acto este último practicado por colectividades enteras con el sólo propósito de negarles a los peninsulares las mieles de la victoria final.

    Semejante encuentro, militarmente disparejo, fue agravado por la llegada con los conquistadores de enfermedades desconocidas en estos lares: paludismo, sarampión, gripe, viruela, etc., y por el hambre

  4. The influence of ambient light on the driver

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

    2018-06-01

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

  9. 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

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.

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

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

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

    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.

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

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

    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

  9. Near-ambient solid polymer fuel cell

    Holleck, G. L.

    1993-01-01

    Fuel cells are extremely attractive for extraterrestrial and terrestrial applications because of their high energy conversion efficiency without noise or environmental pollution. Among the various fuel cell systems the advanced polymer electrolyte membrane fuel cells based on sulfonated fluoropolymers (e.g., Nafion) are particularly attractive because they are fairly rugged, solid state, quite conductive, of good chemical and thermal stability and show good oxygen reduction kinetics due to the low specific adsorption of the electrolyte on the platinum catalyst. The objective of this program is to develop a solid polymer fuel cell which can efficiently operate at near ambient temperatures without ancillary components for humidification and/or pressurization of the fuel or oxidant gases. During the Phase 1 effort we fabricated novel integral electrode-membrane structures where the dispersed platinum catalyst is precipitated within the Nafion ionomer. This resulted in electrode-membrane units without interfacial barriers permitting unhindered water diffusion from cathode to anode. The integral electrode-membrane structures were tested as fuel cells operating on H2 and O2 or air at 1 to 2 atm and 10 to 50 C without gas humidification. We demonstrated that cells with completely dry membranes could be self started at room temperature and subsequently operated on dry gas for extended time. Typical room temperature low pressure operation with unoptimized electrodes yielded 100 mA/cm(exp 2) at 0.5V and maximum currents over 300 mA/cm(exp 2) with low platinum loadings. Our results clearly demonstrate that operation of proton exchange membrane fuel cells at ambient conditions is feasible. Optimization of the electrode-membrane structure is necessary to assess the full performance potential but we expect significant gains in weight and volume power density for the system. The reduced complexity will make fuel cells also attractive for smaller and portable power supplies and as

    2012-12-01

    Lo'ihi seamount, the youngest volcano in the Hawaiian-Emperor chain, lies approximately 30 km south of Hawai'i Island with its summit still approximately 1 km below sea level. Lo'ihi offers a unique opportunity to study the early formation of a hotspot volcano and can provide insight into the deep internal structure of the other volcanoes that make up the Hawaiian Islands. This study uses Ambient Noise Tomography (ANT) to create a 3D tomographic image of Lo'ihi's S-wave velocity structure from ocean bottom seismometer (OBS) data. ANT has been used in many subaerial studies but has seen very few applications to OBS data. This study uses continuous data recorded in 2010 to 2011 from 12 short-period OBS instruments deployed on and around Lo'ihi. With the farthest distance between stations being just over 30 km, the stations provide a fairly dense coverage mainly for the northern half of the volcano. Following the approach of Masterlark et al. [2010], we computed vertical-vertical and vertical-radial cross-correlations using 97 days of continuous data from the 12 stations to produce the ambient noise Green's functions. From these, dispersion curves were produced over a frequency range from .04 Hz to 0.65 Hz . After a quality control analysis, checkerboard tests were used to determine a suitable cell size for the 2D group velocity inversions. The final step is the inversion of the group velocity dispersion curves to create a 3D Vs model. The 3D Vs image produced through this method does not provide clear evidence of a shallow magma chamber; however, when compared to a previous P-wave velocity (Vp) model [Caplan-Auerbach, 2001], a high Vp/Vs ratio is evident especially at depths from 1 km to 5 km, indicating the presence of highly fractured rock.

    Full Text Available The article analyses the effect of two ambient scents (peppermint and vanilla and their intensiveness on risk related behaviour that is expressed through selected decision making heuristics. Purpose of the article: The purpose of this article is to identify the relationship of ambient scent type and intensiveness with risk related behaviour that is expressed through selected decision making heuristics. Methodology/methods: 2×2 factorial experiment with control group was run. Ambient scent type (vanilla vs. peppermint and intensiveness (8 (1mg vs. 16 sprays (2mg of scent concentrate in the same room were manipulated as between subject variables. Risk aversion, effect of anchoring heuristic on bidding, and affect (risk and benefit heuristics were tracked as dependent variables. Scientific aim: To identify whether ambient scent type and intensiveness have effect on risk related behaviour. Findings: Evidence suggests that there are effects of ambient scent on risk related behaviour, thus fulfilling the missing gap to relate ambient environment to decision making heuristics when risks are involved. However, not all heuristics were affected by experimental conditions. Subjects were bidding significantly higher amounts under low anchor conditions, when peppermint scent was around (if compared to vanilla group. Affect risk was perceived as lower in peppermint ambient scent conditions, if compared to the control group. Intensity of ambient scent also had influence on affect risk: subjects perceived less risk under high scent intensity conditions. Conclusions: By manipulating ambient scent, marketers may reduce or increase consumers risk perception and behaviour and as a consequence influence their purchase decisions. Marketers could use peppermint scent in high intensiveness in the situations where they want consumers to undertake higher risks (expensive purchases, gambling, insurance, since stakes were higher under peppermint ambient scent condition

    2008-12-01

    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.

    1985-01-01

    In the fall of 1982, the Environmental Evaluations Section of Pacific Northwest Laboratory (PNL) initiated a network of continuous 85 Kr air samplers located on and around the Hanford Site. This effort was in response to the resumption of operations at a nuclear fuel reprocessing plant located onsite where 85 Kr was to be released during fuel dissolution. Preoperational data were collected using noble gas samplers designed by the Environmental Protection Agency-Las Vegas (EPA-LV). The samplers functioned erratically resulting in excessive maintenance costs and prompted a search for a new sampling system. State-of-the-art 85 Dr sampling methods were reviewed and found to be too costly, too complex and inappropriate for field application, so a simple bag collection system was designed and field tested. The system is composed of a reinforced, heavy plastic bag, connected to a variable flow pump and housed in a weatherproof enclosure. At the end of the four week sampling period the air in the bag is transferred by a compressor into a pressure tank for easy transport to the laboratory for analysis. After several months of operation, the air sampling system has proven its reliability and sensitivity to ambient levels of 85 Kr

  11. Radon-222 related influence on ambient gamma dose.

    2018-04-03

    Ambient gamma dose, radon, and rainfall have been monitored in southern Bucharest, Romania, from 2010 to 2016. The seasonal cycle of background ambient gamma dose peaked between July and October (100-105 nSv h -1 ), with minimum values in February (75-80 nSv h -1 ), the time of maximum snow cover. Based on 10 m a.g.l. radon concentrations, the ambient gamma dose increased by around 1 nSv h -1 for every 5 Bq m -3 increase in radon. Radon variability attributable to diurnal changes in atmospheric mixing contributed less than 15 nSv h -1 to the overall variability in ambient gamma dose, a factor of 4 more than synoptic timescale changes in air mass fetch. By contrast, precipitation-related enhancements of the ambient gamma dose were 15-80 nSv h -1 . To facilitate routine analysis, and account in part for occasional equipment failure, an automated method for identifying precipitation spikes in the ambient gamma dose was developed. Lastly, a simple model for predicting rainfall-related enhancement of the ambient gamma dose is tested against rainfall observations from events of contrasting duration and intensity. Results are also compared with those from previously published models of simple and complex formulation. Generally, the model performed very well. When simulations underestimated observations the absolute difference was typically less than the natural variability in ambient gamma dose arising from atmospheric mixing influences. Consequently, combined use of the automated event detection method and the simple model of this study could enable the ambient gamma dose "attention limit" (which indicates a potential radiological emergency) to be reduced from 200 to 400% above background to 25-50%.

    International Nuclear Information System (INIS)

    Radic, Ljubo; Lilak, Aaron D.; Law, Mark E.

    2002-01-01

    Boron is introduced into silicon via implantation to form p-type layers. This process creates damage in the crystal that upon annealing causes enhanced diffusion and clustering of the boron layer. Reactivation of the boron is not a well-understood process. In this letter we experimentally investigate the effect of the annealing ambient on boron reactivation kinetics. An oxidizing ambient which injects silicon interstitials is compared to an inert ambient. Contrary to published theory, an excess of interstitials does not accelerate the reactivation process

    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 Jet Propulsion Laboratory is involved in a Research and Development program sponsored by NASA/OAST on the development of ambient temperature secondary lithium cells for future space applications. Some of the projected applications are planetary spacecraft, planetary rovers, and astronaut equipment. The main objective is to develop secondary lithium cells with greater than 100 Wh/kg specific energy while delivering 1000 cycles at 50 percent Depth of Discharge (DOD). To realize these ambitious goals, the work was initially focused on several important basic issues related to the cell chemistry, selection of cathode materials and electrolytes, and component development. The performance potential of Li-TiS2, Li-MoS3, Li-V6O13 and Li-NbSe3 electrochemical systems was examined. Among these four, the Li-TiS2 system was found to be the most promising system in terms of realizable specific energy and cycle life. Some of the major advancements made so far in the development of Li-TiS2 cells are in the areas of cathode processing technology, mixed solvent electrolytes, and cell assembly. Methods were developed for the fabrication of large size high performance TiS2 cathodes. Among the various electrolytes examined, 1.5M LiAsF6/EC + 2-MeTHF mixed solvent electrolyte was found to be more stable towards lithium. Experimental cells activated with this electrolyte exhibited more than 300 cycles at 100 percent Depth of Discharge. Work is in progress in other areas such as selection of lithium alloys as candidate anode materials, optimization of cell design, and development of 5 Ah cells. The advances made at the Jet Propulsion Laboratory on the development of secondary lithium cells are summarized.

    Full Text Available Fragrances, such as plant odors, have been shown to evoke autonomic response patterns associated with Ekman’s (Ekman et al., 1983 basic emotions happiness, surprise, anger, fear, sadness and disgust. Inducing positive emotions by odors in highly frequented public spaces could serve to improve the quality of life in urban environments. Thus, the present study evaluated the potency of ambient odors connoted with an urban environment to evoke basic emotions on an autonomic and cognitive response level. Synthetic mixtures representing the odors of disinfectant, candles / bees wax, summer air, burnt smell, vomit and musty smell as well as odorless water as a control were presented five times in random order to 30 healthy, non-smoking human subjects with intact sense of smell. Skin temperature, skin conductance, breathing rate, forearm muscle activity, blink rate and heart rate were recorded simultaneously. Subjects rated the odors in terms of pleasantness, intensity and familiarity and gave verbal labels to each odor as well as cognitive associations with the basic emotions. The results showed that the amplitude of the skin conductance response varied as a function of odor presentation. Burnt smell and vomit elicited significantly higher electrodermal responses than summer air. Also, a negative correlation was revealed between the amplitude of the skin conductance response and hedonic odor valence indicating that the magnitude of the electrodermal response increased with odor unpleasantness. The analysis of the cognitive associations between odors and basic emotions showed that candles / bees wax and summer air were specifically associated with happiness whereas burnt smell and vomit were uniquely associated with disgust. Our findings suggest that city odors may evoke specific cognitive associations of basic emotions and that autonomic activity elicited by such odors is related to odor hedonics.

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

    Full Text Available El presente artículo es el estado del arte sobre el ambiente digital en la comunicación, la actitud y las estrategias pedagógicas utilizadas por docentes, a partir de tres categorías: prácticas y estrategias pedagógicas mediadas por TIC; actitud de docentes en ambientes de aprendizaje mediados por tecnología y estrategias de comunicación docente en ambientes de aprendizaje, con el objetivo de revisar los antecedentes teóricos e investigativos a partir de una revisión documental. El ejercicio condujo a concluir que en la actualidad es importante que los docentes incluyan las TIC en sus prácticas pedagógicas, muestren una actitud positiva ante los ambientes de aprendizaje e implementen el uso de estrategias innovadoras en el aula que promuevan la interacción en redes de conocimiento. Se puede afirmar que los procesos de formación de sujetos capaces de desenvolverse en esta era globalizada requieren de grandes esfuerzos de la comunidad académica por reconocer y utilizar las tecnologías de la información y la comunicación como un elemento transversal en la gestión de conocimiento; por ello, la práctica pedagógica debe ubicarse en senderos propuestos por las nuevas tecnologías, para lo cual se requiere de un trabajo sistemático hacia la comprensión de las nuevas relaciones entre docentes y estudiantes, lo que a su vez, implica el desarrollo de competencias para el aprendizaje colaborativo y la interacción. Otra importante característica que vale la pena recoger aquí es que la comunicación como acto humano es la única que permite el reconocimiento del otro, de la diversidad, de la multiculturalidad, de la vivencia de la alteridad, como ejes fundamentales de las prácticas pedagógicas de los maestros y en general de la vida. La comunicación como una capacidad exclusivamente humana desde la reflexión, la construcción de conocimiento y pensamiento, ha permitido evidenciar el boom de las tecnologías en el mundo

    Ambient mass spectrometry provides great convenience for fast screening, and has showed promising potential in analytical chemistry. However, its relatively low sensitivity seriously restricts its practical utility in trace compound analysis. In this review, we summarize the sampling and analyte enrichment strategies coupled with nine modes of representative ambient mass spectrometry (desorption electrospray ionization, paper vhspray ionization, wooden-tip spray ionization, probe electrospray ionization, coated blade spray ionization, direct analysis in real time, desorption corona beam ionization, dielectric barrier discharge ionization, and atmospheric-pressure solids analysis probe) that have dramatically increased the detection sensitivity. We believe that these advances will promote routine use of ambient mass spectrometry. Graphical abstract Scheme of sampling stretagies for ambient mass spectrometry.

    The monitoring of ambient conditions in indoor spaces is very essential owing to the amount of time spent indoors. Specifically, the monitoring of air quality is significant because contaminated air affects the health, comfort and productivity of occupants. This research work presents a technology review of prototyping platforms for monitoring ambient conditions in indoor spaces. It involves the research on sensors (for CO 2 , air quality and ambient conditions), IoT platforms, and novel and commercial prototyping platforms. The ultimate objective of this review is to enable the easy identification, selection and utilisation of the technologies best suited for monitoring ambient conditions in indoor spaces. Following the review, it is recommended to use metal oxide sensors, optical sensors and electrochemical sensors for IAQ monitoring (including NDIR sensors for CO 2 monitoring), Raspberry Pi for data processing, ZigBee and Wi-Fi for data communication, and ThingSpeak IoT platform for data storage, analysis and visualisation.

    2010-01-01

    This new algorithm, based on GPUs, can compute ambient occlusion to inexpensively approximate global-illumination effects in real-time systems and games. The first step in deriving this algorithm is to examine how ambient occlusion relates to the physically founded rendering equation. The correspondence stems from a fuzzy membership function that defines what constitutes nearby occlusions. The next step is to develop a method to calculate ambient occlusion in real time without precomputation. The algorithm is based on a novel interpretation of ambient occlusion that measures the relative volume of the visible part of the surface's tangent sphere. The new formula's integrand has low variation and thus can be estimated accurately with a few samples.

    Depletion of the ozone layer has meant that ambient ultraviolet radiation (UVR) has increased in recent decades. At the same time, the incidence of skin cancers, including melanoma, has risen. The relatively few large-scale studies that linked ambient UVR to melanoma found a trend toward rising incidence closer to the equator, where UVR estimates are highest. Similar research has not been conducted in Canada, where ambient UVR is generally lower than in countries further south. Modelled UVR data for the months of June through August during the 1980-to-1990 period were spatially linked in Geographic Information Systems to 2.4 million white members of the 1991 Canadian Census Health and Environment Cohort and tracked for melanoma diagnosis over an 18-year period (1992 to 2009). Standard Cox proportional hazards models were used to estimate melanoma risk associated with increases of ambient summer UVR, assigned by residence at baseline. Models were adjusted for age, sex and socioeconomic (SES) characteristics. Separate analyses by body site of melanoma were conducted. Effect modification of the association between ambient UVR and melanoma by sex, age, outdoor occupation and selected SES characteristics was evaluated. Differences of one standard deviation (446 J/m², or 7% of the mean) in average ambient summer UVR were associated with an increased hazard ratio (HR) for melanoma of 1.22 (95% CI: 1.19 to 1.25) when adjusting for sex, age and SES characteristics. The HR for melanoma in relative UVR (per 1 standard deviation) was larger for men (HR = 1.26; 95% CI: 1.21 to 1.30) than for women (HR = 1.17; 95% CI: 1.13 to 1.22). Ambient summer UVR is associated with a greater risk of melanoma among the white population, even in a country where most people live within a narrow latitudinal belt. A stronger association between melanoma and ambient UVR was evident among men and among people of lower SES.

    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.

    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.

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.

    Some prior studies have linked ambient temperature with risk of cerebrovascular events. If causal, the pathophysiologic mechanisms underlying this putative association remain unknown. Temperature-related changes in cerebral vascular function may play a role, but this hypothesis has not been previously evaluated. We evaluated the association between ambient temperature and cerebral vascular function among 432 participants ≥65 years old from the MOBILIZE Boston Study with data on cerebrovascular blood flow, cerebrovascular resistance, and cerebrovascular reactivity in the middle cerebral artery. We used linear regression models to assess the association of mean ambient temperature in the previous 1 to 28 days with cerebrovascular hemodynamics adjusting for potential confounding factors. A 10°C increase in the 21-day moving average of ambient temperature was associated with a 10.1% (95% confidence interval [CI], 2.2%, 17.3%) lower blood flow velocity, a 9.0% (95% CI, 0.7%, 18.0%) higher cerebrovascular resistance, and a 15.3% (95%CI, 2.7%, 26.4%) lower cerebral vasoreactivity. Further adjustment for ozone and fine particulate matter (PM2.5) did not materially alter the results. However, we found statistically significant interactions between ambient temperature and PM2.5 such that the association between temperature and blood flow velocity was attenuated at higher levels of PM2.5. In this elderly population, we found that ambient temperature was negatively associated with cerebral blood flow velocity and cerebrovascular vasoreactivity and positively associated with cerebrovascular resistance. Changes in vascular function may partly underlie the observed associations between ambient temperature and risk of cerebrovascular events.

  2. Plume Splitting in a Two-layer Stratified Ambient Fluid

    2017-11-01

    A line-source plume descending into a two-layer stratified ambient fluid in a finite sized tank is studied experimentally. Although the total volume of ambient fluid is fixed, lower- and upper-layer fluids are respectively removed and added at a constant rate mimicking marine outfall through diffusers and natural and hybrid ventilated buildings. The influence of the plume on the ambient depends on the value of λ, defined as the ratio of the plume buoyancy to the buoyancy loss of the plume as it crosses the ambient interface. Similar to classical filling-box experiments, the plume can always reach the bottom of the tank if λ > 1 . By contrast, if λ < 1 , an intermediate layer eventually forms as a result of plume splitting. Eventually all of the plume fluid spreads within the intermediate layer. The starting time, tv, and the ending time, tt, of the transition process measured from experiments correlate with the value of λ. A three-layer ambient fluid is observed after transition, and the mean value of the measured densities of the intermediate layer fluid is well predicted using plume theory.

    We examined the association between prostate-specific antigen (PSA) and daily mean ambient temperature on the day of the test in healthy men who had three annual checkups. We investigated 9,694 men who visited a hospital for routine health checkups in 2007, 2008, and 2009. Although the means and medians of ambient temperature for the three years were similar, the mode in 2008 (15.8 °C) was very different from those in 2007 and 2009 (22.4 °C and 23.2 °C). After controlling for age, body mass index, and hematocrit, a multiple regression analysis revealed a U-shaped relationship between ambient temperature and PSA in 2007 and 2009 ( P 2.5 ng/mL) by ambient temperature, with the lowest likelihood of having a high PSA at 17.8 °C in 2007 ( P = 0.038) and 15.5 °C in 2009 ( P = 0.033). When tested at 30 °C, there was a 57 % excess risk of having a high PSA in 2007 and a 61 % higher risk in 2009 compared with those at each nadir temperature. We found a U-shaped relationship between PSA and ambient temperature with the lowest level of PSA at 15-20 °C.

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

    The spectrum of ambient seismic noise shows strong signals associated with tropical cyclones, yet a detailed understanding of these signals and the relationship between them and the storms is currently lacking. Through the analysis of more than a decade of seismic data recorded at several stations located in and adjacent to the northwest Pacific Ocean, here we show that there is a persistent and frequency-dependent signature of tropical cyclones in ambient seismic noise that depends on characteristics of the storm and on the detailed location of the station relative to the storm. An adaptive statistical model shows that the spectral amplitude of ambient seismic noise, and notably of the short-period secondary microseisms, has a strong relationship with tropical cyclone intensity and can be employed to extract information on the tropical cyclones.

    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

    The principle of present work lies on the dependence of the threshold neutron energy on the dimensionless quantity ''degree of metastability (ss)'' of superheated liquids. The response of the superheated emulsions consists of the drops of superheated liquid (C 2 Cl 2 F 4 , b.p. 3.77 deg. C) has been measured at different 'ss' by varying ambient pressure at different temperatures, in the presence of neutrons generated in Pb by a (γ,n) reaction from 45 MeV electron LINAC of Hokkaido University. To unfold the neutron energy spectrum, a relationship has been developed between the 'ss' of superheated liquids and the threshold neutron energy. The spectrum at the detector position has been calculated by the MCNP code and a comparison has been made with the experimental spectrum. The utilisation of 'ss' is more flexible as this relation can be applied to both positive and negative ambient pressures as well as at different ambient temperatures

    The deleterious effects of ambient air pollution on human health have been consistently documented by many epidemiologic studies worldwide, and it has been calculated that globally at least seven million deaths are annually attributable to the effects of air pollution. The major air pollutants emitted into the atmosphere by a number of natural processes and human activities include nitrogen oxides, volatile organic compounds, and particulate matter. In addition to the poor ambient air quality, there is increasing evidence that indoor air pollution also poses a serious threat to human health, especially in low-income countries that still use biomass fuels as an energy resource. This review summarizes the current knowledge on ambient air pollution in financially deprived populations.

    In this work, the effect of an ambient plasma treatment powered by compressed dry air on the passivation quality of silicon wafers coated with intrinsic amorphous silicon sub-oxide is investigated. While long-time storage deteriorates the effective lifetime of all samples, a short ambient plasma treatment improves their passivation qualities. By studying the influence of the plasma treatment parameters on the passivation layers, an optimized process condition was identified which even boosted the passivation quality beyond its original value obtained immediately after deposition. On the other hand, the absence of stringent requirement on gas precursors, vacuum condition and longtime processing makes the ambient plasma treatment an excellent candidate to replace conventional thermal annealing in industrial heterojunction solar cell production.

    2017-03-28

    This work details two approaches for evaluating transmission warming technology: experimental dynamometer testing and development of a simplified transmission efficiency model to quantify effects under varied real world ambient and driving conditions. Two vehicles were used for this investigation: a 2013 Ford Taurus and a 2011 Ford Fusion. The Taurus included a production transmission warming system and was tested over hot and cold ambient temperatures with the transmission warming system enabled and disabled. A robot driver was used to minimize driver variability and increase repeatability. Additionally the Fusion was tested cold and with the transmission pre-heated prior to completing the test cycles. These data were used to develop a simplified thermally responsive transmission model to estimate effects of transmission warming in real world conditions. For the Taurus, the fuel consumption variability within one standard deviation was shown to be under 0.5% for eight repeat Urban Dynamometer Driving Cycles (UDDS). These results were valid with the transmission warming system active or passive. Using the transmission warming system under 22 degrees C ambient temperature, fuel consumption reduction was shown to be 1.4%. For the Fusion, pre-warming the transmission reduced fuel consumption 2.5% for an urban drive cycle at -7 degrees C ambient temperature, with 1.5% of the 2.5% gain associated with the transmission, while consumption for the US06 test was shown to be reduced by 7% with 5.5% of the 7% gain associated with the transmission. It was found that engine warming due to conduction between the pre-heated transmission and the engine resulted in the remainder of the benefit. For +22 degrees C ambient tests, the pre-heated transmission was shown to reduce fuel consumption approximately 1% on an urban cycle, while no benefit was seen for the US06 cycle. The simplified modeling results showed gains in efficiency ranging from 0-1.5% depending on the ambient

    To better understand how different ambient temperatures during lactation affect survival of young, we studied patterns of losses of pups in golden hamsters ( Mesocricetus auratus ) at different ambient temperatures in the laboratory, mimicking temperature conditions in natural habitats. Golden hamsters produce large litters of more than 10 young but are also known to wean fewer pups at the end of lactation than they give birth to. We wanted to know whether temperature affects litter size reductions and whether the underlying causes of pup loss were related to maternal food (gross energy) intake and reproductive performance, such as litter growth. For that, we exposed lactating females to three different ambient temperatures and investigated associations with losses of offspring between birth and weaning. Overall, around one third of pups per litter disappeared, obviously consumed by the mother. Such litter size reductions were greatest at 30 °C, in particular during the intermediate postnatal period around peak lactation. Furthermore, litter size reductions were generally higher in larger litters. Maternal gross energy intake was highest at 5 °C suggesting that mothers were not limited by milk production and might have been able to raise a higher number of pups until weaning. This was further supported by the fact that the daily increases in litter mass as well as in the individual pup body masses, a proxy of mother's lactational performance, were lower at higher ambient temperatures. We suggest that ambient temperatures around the thermoneutral zone and beyond are preventing golden hamster females from producing milk at sufficient rates. Around two thirds of the pups per litter disappeared at high temperature conditions, and their early growth rates were significantly lower than at lower ambient temperatures. It is possible that these losses are due to an intrinsic physiological limitation (imposed by heat dissipation) compromising maternal energy intake and

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

    2017-12-01

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

Air conditioning, for example, accounts for nearly fifteen per cent of the primary energy used by buildings in the United States. A passive cooling strategy that cools without any electricity input could therefore have a significant impact on global energy consumption. To achieve cooling one needs to be able to reach and maintain a temperature below that of the ambient air. At night, passive cooling below ambient air temperature has been demonstrated using a technique known as radiative cooling, in which a device exposed to the sky is used to radiate heat to outer space through a transparency window in the atmosphere between 8 and 13 micrometres. Peak cooling demand, however, occurs during the daytime. Daytime radiative cooling to a temperature below ambient of a surface under direct sunlight has not been achieved because sky access during the day results in heating of the radiative cooler by the Sun. Here, we experimentally demonstrate radiative cooling to nearly 5 degrees Celsius below the ambient air temperature under direct sunlight. Using a thermal photonic approach, we introduce an integrated photonic solar reflector and thermal emitter consisting of seven layers of HfO2 and SiO2 that reflects 97 per cent of incident sunlight while emitting strongly and selectively in the atmospheric transparency window. When exposed to direct sunlight exceeding 850 watts per square metre on a rooftop, the photonic radiative cooler cools to 4.9 degrees Celsius below ambient air temperature, and has a cooling power of 40.1 watts per square metre at ambient air temperature. These results demonstrate that a tailored, photonic approach can fundamentally enable new technological possibilities for energy efficiency. Further, the cold darkness of the Universe can be used as a renewable thermodynamic resource, even during the hottest hours of the day.

  3. EPISTEMOLOGIA AMBIENTAL: A crise ambiental como uma crise da razão

    2013-04-01

    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.

    The development of rapid screening and identification techniques is of great importance for drug discovery, doping control, forensic identification, food safety and quality control. Ambient mass spectrometry (AMS) allows rapid and direct analysis of various samples in open air with little sample preparation. Recently, its applications in high-throughput screening have been in rapid progress. During the past decade, various ambient ionization techniques have been developed and applied in high-throughput screening. This review discusses typical applications of AMS, including DESI (desorption electrospray ionization), DART (direct analysis in real time), EESI (extractive electrospray ionization), etc., in high-throughput screening (HTS).

    A great deal of interest has been generated in the use of cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) detectors for ambient temperature detection of radionuclides. The addition of zinc to CdTe provides several benefits that enhance the materials operational characteristics at ambient temperature. Recent movement in the industry is to produce larger volume detectors using CdZnTe without much known about the effects of larger geometry on performance. The purpose of this study is to get an idea of the relationship of detector performance to both area and thickness variations

    A second low-temperature agent, krypton difluoride, for generating volatile plutonium hexafluoride is reported (dioxygen difluoride is the only other reported agent). Plutonium hexafluoride is formed at ambient or lower temperature by the treatment of various solid substrates with krypton difluoride. Volatilization of uranium and neptunium from solid substrates using gaseous krypton difluoride is also reported for the first time. The formation of actinide hexafluorides has been confirmed for the reaction of krypton difluoride in anhydrous HF with UO 2 and with uranium and neptunium fluorides at ambient temperatures. Treatment of americium dioxide with krypton difluoride did not yield americium hexafluoride under the conditions studied. 15 references, 2 figures

    2010-03-01

    Full Text Available Historicamente a relação social e humana com o meio ambiente sempre implicou em algum tipo de destruição e degradação. Com a constituição da sociedade industrial capitalista e seu desdobramento em sociedade de consumo de massa, esse avanço sobre os recursos naturais tem se dado de forma tão radical que ameaça a continuidade da vida e da biosfera como a conhecemos nos últimos milênios. O texto reflete sobre a relação entre a violência social e o meio ambiente a partir de um feixe de teorias e conceitos provenientes do cruzamento da questão ambiental, da teoria crítica, da teoria da complexidade, da teoria da sociedade de risco e de contribuições de filosofias tradicionais como o Budismo. Os conceitos considerados são os de sustentabilidade, de interdependência, de cidadania ambiental e de justiça socioambiental. Nesse sentido, procura investigar as raízes sociais e psicossociais da violência que condicionam as relações e instituições sócio-culturais, entre as quais figuram a própria ciência, como saber social hegemônico, e a educação; observar suas implicações sobre a vida social e ambiental; e verificar a possível contribuição da educação, em geral, e da educação ambiental como foco curricular, em particular, para transformar ou reorientar essas forças e práticas associadas à violência para fins mais pacíficos e construtivos.

Metodológicamente se trata de una sistematización a partir de fuentes bibliográficas primarias y secundarias disponibles inclusive en bases indexadas. Podemos concluir que el ejercicio profesional de enfermería en el siglo XXI exige enfrentar el desafío de (redimensionar el cuidado, que debe ser entendido no como un acto y si como una actitud cuidadora y un compromiso con la defensa de la vida de ésta y las futuras generaciones.This article is a result of the necessity of discussing the many impacts that the globalization process, since it affects way the political, economical and social relations, that are expressed in the environmental degradation and becomes a strong threat to the health of individuals and communities in the local and global levels. Intends to stimulate a reflection from the interdisciplinary analysis of the developed knowledge about categories like globalization, environment and health, and their articulation with the professional nursing practice. In a methodological point of view, it is systematization from primary and secondary bibliographic sources including indexed ones. We conclude that the professional nursing practice in the XXI century demands confronting the challenge of resize the concept of nursing care, must be understood not as an act but as a caring actitude and a commitment to the protection of life of this and future's generations.

    2017-12-01

    The study of ambient seismic noise is one of the important scientific and practical research challenges, due to its use in a number of geophysical applications. In this work, we describe Earth's ambient noise fluctuations in terms of non-extensive statistical physics. We found that Earth's ambient noise increments follow the q-Gaussian distribution. This indicates that Earth's ambient noise's fluctuations are not random and present long-term memory effects that could be described in terms of Tsallis entropy. Our results suggest that q values depend on the time length used and that the non-extensive parameter, q, converges to value q → 1 for short-time windows and a saturation value of q ≈ 1.33 for longer ones. The results are discussed from the point of view of superstatistics introduced by Beck [Contin Mech Thermodyn 16(3):293-304, 2004] and connects the q values with the system's degrees of freedom. Our work indicates that the converged (maximum) value is q = 1.33 and is related to 5 degrees of freedom.

    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)).

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

    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.

  15. Effects of ambient conditions on fuel cell vehicle performance

    Science.gov (United States)

    Haraldsson, K.; Alvfors, P.

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

    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. 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. 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. 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. Ambient air pollution may impact human olfactory function. Additional studies are needed to examine air pollution-related olfactory impacts on the general population using measured

    It is well known that many biochemical processes in the cell such as gene regulation, growth signals and activation of ion channels, rely on mechanical stimuli. However, the mechanism by which mechanical signals propagate through cells is not as well understood. In this review we focus on stress propagation in a minimal model for cell elasticity, actomyosin networks, which are comprised of a sub-family of cytoskeleton proteins. After giving an overview of th actomyosin network components, structure and evolution we review stress propagation in these materials as measured through the correlated motion of tracer beads. We also discuss the possibility to extract structural features of these networks from the same experiments. We show that stress transmission through these networks has two pathways, a quickly dissipative one through the bulk, and a long ranged weakly dissipative one through the pre-stressed actin network.

    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.

    Full Text Available La finalidad del trabajo es aportar información y propuestas conceptuales que faciliten la tarea de quienes tienen a su cargo la sistematización institucional de la salud ambiental. Se hace un análisis de la noción de "ambiente" para la cual se sugiere una definición, y se examina el lugar de la salud ambiental en el contexto de los problemas ambientales y sus vertientes "verde" y "azul". Se examinan denominaciones equivalentes de salud ambiental y se introducen los servicios de salud ambiental. Se proporcionan varias definiciones y se da la oficial de salud ambiental adoptada por la OMS en Sofía, Bulgaria (1993. A continuación se transcriben las áreas básicas que a la salud ambiental le han asignado diversas organizaciones o reuniones, como la OPS, la OMS, el Programa 21 y otros. A partir de aquí se construye un repertorio bastante completo de áreas y subáreas y se encuentra que todos los listados son, en realidad, una reunión asistemática de tres tipos de constituyentes: determinantes (factores o hechos de la realidad física, procesos (conjuntos de intervenciones y funciones (conjuntos de acciones de gestión, los cuales pueden enfocarse matricialmente y llevan a individualizar actividades de los servicios de salud ambiental. Se proponen unas reglas de operación que permiten, en una especie de álgebra, construir expresiones para especificar con precisión las actividades y sus agregados. De este modo se logra disponer de un lenguaje simbólico común que puede ayudar a la intercomunicación, enseñanza e investigación en el ámbito de la salud ambiental.The objective of this study is to provide information and a conceptual framework that will facilitate the work of persons in charge of systematizing institutions devoted to environmental health.

    Full Text Available A educação ambiental garante espaço nas escolas brasileiras como uma importante proposta para o enfrentamento dos problemas ambientais, porém, costuma ter uma concepção conservadora e, assim, ser desconexa das realidades locais. Para tanto, o artigo visa analisar a educação ambiental ensinada nos ambientes escolares no município de Diamantina/MG, a fim de atualizá-la temporo-espacialmente. As prioridades ambientais do entorno de nove escolas do ensino fundamental foram registradas via mapeamento participativo, juntamente à análise dos livros didáticos adotados por estes locais de modo a identificar e caracterizar suas abordagens ambientais. De modo geral, os produtos cartográficos representaram questões associadas a resíduos sólidos, efluentes e poluições hídrica, sonora e atmosférica, sem trazer elementos que apontem para as relações de poder e os consequentes embates por hegemonia que estrutura a sociedade moderna. E os materiais didáticos apresentam temas ambientais em sua composição, mas a maioria de forma simplificada e descontextualizada, o que contribui para os resultados alcançados nas atividades de mapeamento participativo. Como construção criativa e coletiva, a educação ambiental crítica urge-se diante da crise ambiental e, portanto, a atualização temporal e espacial das temáticas ambientais se torna, desde já, uma tarefa necessária.

    2010-06-30

    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.

    In this paper we introduce the context of a semiconductor factory as a promising area for the application of innovative interaction approaches. In order to increase efficiency ambient persuasive interfaces, which influence the operators' behaviour to perform in an optimized way, could constitute a potential strategy. We present insights gained from qualitative studies conducted in a specific semiconductor factory and provide a description of typical work processes and already deployed interfaces in this context. These findings informed the design of a prototype of an ambient persuasive interface within this realm - the "Operator Guide". Its overall aim is to improve work efficiency, while still maintaining a minimal error rate. We provide a detailed description of the Operator Guide along with an outlook of the next steps within a user-centered design approach.

    This paper discusses generation asset valuation in a framework where capital utilization decisions are endogenous. We use real options approach for valuation of natural gas fueled turbines. Capital utilization choices that we explore include turning on/off the unit, operating the unit at increased firing temperatures (overfiring), and conducting preventive maintenance. 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. Photoelectron spectroscopy under ambient pressure and temperature conditions

    International Nuclear Information System (INIS)

    Frank Ogletree, D.; Bluhm, Hendrik; Hebenstreit, Eleonore D.; Salmeron, Miquel

    2009-01-01

    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 of 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.

    1983-01-01

    A study was undertaken to test the hypothesis that change in ambient air temperature has an effect on MAST suit pressure according to the ideal gas law. Two different MAST suits were tested on Resusci-Annie dummies. The MAST suits were applied in a cold room at 4.4 degrees C and warmed to 44 degrees C. Positive linear correlations were found in nine trials, but the two suits differed in their rate of increase in pressure. Three trials using humans were conducted showing increased pressure with temperature but at a lesser rate than with dummies. A correlation of 0.5 to 1.0 mm Hg increase in MAST suit pressure for each 1.0 degrees C increase in ambient temperature was found. Implications are discussed for the use of the MAST suit in environmental conditions where the temperature changes.

    Using two desorption/ionization techniques (DESI and EASI) and Brazilian real, US$ dollar, and euro bills as proof-of-principle techniques and samples, direct analysis by ambient mass spectrometry is shown to function as an instantaneous, reproducible, and non-destructive method for chemical analysis of banknotes. Characteristic chemical profiles were observed for the authentic bills and for the counterfeit bills made using different printing processes (inkjet, laserjet, phaser and off-set printers). Detection of real-world counterfeit bills and identification of the counterfeiting method has also been demonstrated. Chemically selective 2D imaging of banknotes has also been used to confirm counterfeiting. The nature of some key diagnostic ions has also been investigated via high accuracy FTMS measurements. The general applicability of ambient MS analysis for anti-counterfeiting strategies particularly via the use of "invisible ink" markers is discussed.

The bottom ash geopolymer concrete was prepared with sodium based alkaline activators under ambient curing temperatures. The sodium hydroxide used concentration was 8M. The performance of BA GPC was compared with conventional concrete. The test results indicate that BA GPC developes a strong passive layer against chloride ion diffusion and provides better protection against corrosion. Both the initial and final rates of water absorption of BA GPC were about two times less than those of conventional concrete. The BA GPC significantly enhanced performance over equivalent grade conventional concrete (CC.

  10. Ambient Intelligence 2.0: Towards Synergetic Prosperity

    Science.gov (United States)

    Aarts, Emile; Grotenhuis, Frits

    Ten years of research in Ambient Intelligence have revealed that the original ideas and assertions about the way the concept should develop no longer hold and should be substantially revised. Early scenario's in Ambient Intelligence envisioned a world in which individuals could maximally exploit personalized, context aware, wireless devices thus enabling them to become maximally productive, while living at an unprecedented pace. Environments would become smart and proactive, enriching and enhancing the experience of participants thus supporting maximum leisure possibly even at the risk of alienation. New insights have revealed that these brave new world scenarios are no longer desirable and that people are more in for a balanced approach in which technology should serve people instead of driving them to the max. We call this novel approach Synergetic Prosperity, referring to meaningful digital solutions that balance mind and body, and society and earth thus contributing to a prosperous and sustainable development of mankind.

  11. Ambient ultraviolet radiation causes mortality in salamander eggs

    International Nuclear Information System (INIS)

    1995-01-01

    Previous research has shown that amphibian species have differential sensitivity to ultraviolet-B (UV-B) radiation. In some anuran species, ambient levels of UV-B cause mortality in embryonic stages and hatching success is significantly reduced. Projected increases in UV-B may affect an increasing number of species. The adverse effects of UV-B may eventually be manifested at the population level and may ultimately contribute to population declines. Using field experiments, we investigated the effects of ambient UV-B on salamander (Ambystoma gracile) embryos developing at natural oviposition sites. We show that the hatching success of eggs of A. gracile shielded from UV-B is significantly higher than those not shielded from UV-B. 27 refs., 1 fig

    Animal studies show reduced nociceptive responses to noxious heat stimuli and increases in endogenous beta-endorphin levels in cold environments, suggesting that human pain perception may be dependent on ambient temperature. However, studies of changes in local skin temperature on human pain perception have yielded variable results. This study examines the effect of both warm and cool ambient temperature on the perception of noxious and innocuous mechanical and thermal stimuli. Ten subjects (7 men and 3 women, aged 20-23 yr) used visual analog scales to rate the stimulus intensity, pain intensity, and unpleasantness of thermal (0-50 degrees C) and mechanical (1.2-28.9 g) stimuli applied on the volar forearm with a 1-cm2 contact thermode and von Frey filaments, respectively. Mean skin temperatures were measured throughout the experiment by infrared pyrometer. Each subject was tested in ambient temperatures of 15 degrees C (cool), 25 degrees C (neutral), and 35 degrees C (warm) on separate days, after a 30-min acclimation to the environment. Studies began in the morning after an 8-h fast. Mean skin temperature was altered by ambient temperature (cool room: 30.1 degrees C; neutral room: 33.4 degrees C; warm room: 34.5 degrees C; P cool than in the neutral environment (P cool room and that noxious heat stimuli were more unpleasant in a warm environment. Environmental temperature did not alter ratings of warm (37 and 40 degrees C) or mechanical stimuli. These results indicate that, in humans, a decrease in skin temperature following exposure to cool environments reduces thermal pain. Suppression of Adelta primary afferent cold fiber activity has been shown to increase cold pain produced by skin cooling. Our current findings may represent the reverse phenomenon, i.e., a reduction in thermal nociceptive transmission by the activation of Adelta cutaneous cold fibers.

    Lung function is complex trait with both genetic and environmental factors contributing to variation. It is unknown how geographic factors such as climate affect population respiratory health. To determine whether ambient air temperature is associated with lung function (FEV1) in the general population. Associations between spirometry data from two National Health and Nutrition Examination Survey (NHANES) periods representative of the U.S. non-institutionalized population and mean annual ambient temperature were assessed using survey-weighted multivariate regression. The NHANES III (1988-94) cohort included 14,088 individuals (55.6% female) and the NHANES 2007-12 cohort included 14,036 individuals (52.3% female), with mean ages of 37.4±23.4 and 34.4±21.8 years old and FEV1 percent predicted values of 99.8±15.8% and 99.2±14.5%, respectively. After adjustment for confounders, warmer ambient temperatures were associated with lower lung function in both cohorts (NHANES III p = 0.020; NHANES 2007-2012 p = 0.014). The effect was similar in both cohorts with a 0.71% and 0.59% predicted FEV1 decrease for every 10°F increase in mean temperature in the NHANES III and NHANES 2007-2012 cohorts, respectively. This corresponds to ~2 percent predicted difference in FEV1 between the warmest and coldest regions in the continental United States. In the general U.S. population, residing in regions with warmer ambient air temperatures was associated with lower lung function with an effect size similar to that of traffic pollution. Rising temperatures associated with climate change could have effects on pulmonary function in the general population.

    This paper makes use of a smartphone's ambient light sensor to analyse a system of two coupled springs undergoing either simple or damped oscillatory motion. The period, frequency and stiffness of the spring, together with the damping constant and extinction time, are extracted from light intensity curves obtained using a free Android application. The results demonstrate the instructional value of mobile phone sensors as a tool in the physics laboratory. (paper)
