    Listeria monocytogenes é o agente infeccioso responsável pela doença de origem alimentar denominada listeriose. Apesar de baixa incidência, a listeriose representa importante risco à saúde pública, pelo grau de severidade das seqüelas e alto índice de mortalidade (20% a 30% que promove em populações de risco, como pacientes imunocomprometidos, idosos e gestantes. No Brasil e em outros países em desenvolvimento, além da falta de preocupação por parte das autoridades de saúde pública em relação à sua disseminação, não há estatísticas oficiais de casos de listeriose, pois sua notifi cação não é obrigatória. Considerando o aumento da incidência de L. monocytogenes no mundo todo, e a falta de informações atualizadas na língua portuguesa sobre o comportamento desta bactéria, sua prevalência, fatores de virulência e outros aspectos relevantes para a saúde pública, se elaborou esta revisão.

    The aim of the present study is to identify and analyze the factors, motivations and criteria being considered in the decision-making processes of the actors belonging to the biodiesel production chain in RS, and confirm or otherwise, the existence of alignment in the decision-making process. Interviews were carried out with the main agents of the links that comprise the biodiesel chains in RS: 11 agricultural co-operatives, 3 biodiesel production plants and a firm that processes and distributes diesel/biodiesel. With regard the decision-making process of the cooperatives, it is centered on the decision to offer, or otherwise, oil-bearing crops for the production of biodiesel. Their decisions emphasize operational and short-term aspects. In contrast, in the firms producing biodiesel, their decision to produce this fuel is associated with addition of one more product to their market portfolio, and is correlated with a long-term view and the search for economic efficiency. In these firms, the benefits of the tax incentives offered by the public policies strongly influence the decision regarding the alternative oil-bearing crops used in the production of biodiesel. In the distributor, it was seen that the decision-making process was guided by long-term strategies. The decision to mix biodiesel with diesel oil being related to the institutional aspect, whatever the legal obligation to mix the fuels may be. In summary, the results show the existence of different characteristics linked to the decision-making process and a significant lack of synchronicity in the aims and motivations of the agents decisions. This state of decisional mis-alignment, associated with the fragilities of public policy, leads to heightened uncertainty regarding the sustainability of the Brazilian biodiesel production program.

    Full Text Available Los miembros de la familia de receptores celulares, integrinas (·V‚1, ·V‚3 ·V‚6, han sido identificados como factores de adhesión de diferentes virus a las células del hospedero. Para el caso del virus de la Fiebre Aftosa, estas integrinas se unen al sitio de reconocimiento celular en la secuencia tripéptidica Arg-Gly-Asp (RGD e igualmente están localizadas en la proteína VP1 del virus. Evidencia genética de esta interacción ha sido obtenida mediante la mutación de la secuencia RGD en clones infecciosos de ADNc, identificando partículas virales no infectivas incapaces de absorberse a células susceptibles. Cierta clase de resistencia genética natural al virus de la fiebre aftosa ha sido descrita en el ganado bovino Blanco Orejinegro, considerándose que cierto grado de esta resistencia podría ser causado por mutaciones en estos receptores celulares responsables por la adhesión del virus. Uno de los objetivos del estudio fue la identificación de genes candidatos (integrinas, específicamente marcadores moleculares asociados a genes  potencialmente responsables por la adhesión del virus aftoso a la célula hospedera. Un total de 106 individuos pertenecientes al núcleo de ganado criollo (banco de germoplasma bovino, Corpoica fueron genotipados con dos marcadores tipo microsatélite (ILS030 y BM2113 y dos SNPs (SLC11A1 y ITGB6 encontrados en el cromosoma 2 bovino.

    Full Text Available Se trata de un estudio transversal, cuantitativo, cuyo objetivo fue verificar los factores familiares protectores y de riesgo relacionados al consumo de drogas en adolescentes, considerando los patrones de interacción que se desarrollan en la familia, sus grados de adaptabilidad y vulnerabilidad. Participaron del estudio 80 adolescentes de género femenino, del 1º al 4º año de la Enseñanza Media, que respondieron a un cuestionario. Se establecieron los factores de riesgo y protección de mayor relevancia que estarían influyendo en esta situación, tales como, patrones de interacción, grado de adaptabilidad, modo de afrontamiento de los problemas, recursos de la familia y valores. Los factores de mayor riesgo fueron el modo de enfrentar los problemas, y dentro de estos, la falta de apoyo religioso y la búsqueda de apoyo profesional, conjuntamente con las dificultades de comunicación intrafamiliares. Los de menor riesgo fueron los valores, como el esfuerzo personal. Los resultados obtenidos resaltan que el enfermero debe asumir como parte de su rol las intervenciones psicosociales, especialmente en la población escolar, ya que así estarían actuando como agentes de prevención del consumo de drogas.

    Full Text Available OBJECTIVE: The objective of this study was to analyze the potential risks involved in the administration process of intravenous anti-infective medication at a medical clinic, using the Failure Mode and Effect Analysis. METHOD: This exploratory study was conducted at the medical clinic of a hospital in the State of Goiás. For data collection we convened a team comprised of six professionals involved in medication treatment: a doctor, nurse, nursing technician, pharmacist, a nursing and a risk manager. A total of 24 meetings were held, for a total of 56 hours. The data were transcribed into an electronic database within Microsoft Excel®, and the Xfmea4 software was used. RESULT: The results indicated 52 failure modes, 79 effects of failure, and 285 causes of failure. The causes were related to: the management of organizational processes, human resources, physical and material structure. A total of 298 actions for improvement were recommended for 215 causes of high and average priority, 81.9% of which were short-term priorities. The simulation of the impact of the proposed interventions revealed a 79.7% reduction of the high-priority failure modes. CONCLUSION: It was concluded that the study identified potential risks to patients and recommended proactive actions, of rapid application and low cost, evaluated positively in the reduction of risk of occurrence of avoidable incidents, increasing reliability and safety of the medication administration process. Studies like this demonstrate that, with the application of a method of risk analysis, nurses can effectively assist in preventing medication incidents.OBJETIVO: Este estudio objetivó analizar los riesgos potenciales de administración de medicamentos anti-infecciosos por vía endovenosa en una unidad de Clínica Médica, utilizando el Método de Análisis del Modo y Efecto de Falla.

Métodos: A pesquisa foi realizada entre os meses de julho/2013 e julho/2014 e utilizou-se os questionários Nórdico de Sintomas Osteomusculares e o SF-36, em 56 voluntários. Resultados: Observou-se maior severidade dos sintomas na região dos ombros e cervical, e baixas médias de QV em todos os domínios, com relação significativa entre sexo e sintomatologia nos membros superiores, e entre componentes mentais e físicos da QV e a sintomatologia em ombros e punhos. Considerações finais: Esta pesquisa possuiu limites metodológicos relacionados ao reduzido número de indivíduos da amostra, no entanto, ainda assim, foi possível atingir seus objetivos, através da análise do perfil ocupacional, da sintomatologia osteomuscular e da QV dos trabalhadores notificados como portadores de DORT no estado de Sergipe. A QV do portador de DORT é reduzida, embora sua relação com a sintomatologia da doença precise ser investigada mais profundamente.

    Full Text Available Nosso objetivo foi avaliar medo, ansiedade e controle relacionados ao tratamento odontológico. Os sujeitos foram 364 crianças da faixa etária de 7 a 13 anos. Três questionários com questões de múltipla escolha foram aplicados em grupos de 10 crianças. O primeiro questionário destinou-se à avaliação do medo ao tratamento odontológico e outras situações. Foi traduzido e adaptado do "Child's Fear Survey Schedule"9 e contém 15 itens. O segundo questionário contém 20 itens relacionados as situações potencialmente produtoras de ansiedade. Foi traduzido e adaptado do "State Trait Anxiety Inventory for Children"16. O terceiro questionário contém 40 itens sendo 20 relacionados ao controle percebido e 20 ao controle desejado e foi traduzido e adaptado do "Child Dental Control Assessment"19. Em relação ao medo e ansiedade, a média dos escores foi mais elevada para o sexo feminino do que para o sexo masculino (P < 0,05. Em relação a idade, as crianças da faixa de 11 a 13 anos revelaram-se em média mais temerosas que as de 7 a 9 anos. Quanto ao controle percebido as crianças mais novas percebem mais controle do que as mais velhas. Em geral os dados indicam que valores mais altos de medo relacionam-se com valores mais baixos de controle percebido. As crianças que tinham realizado tratamento odontológico com anestesia mostraram-se mais temerosas do que aquelas que não foram submetidas a anestesia, o que permite inferir que a etiologia de medo pode relacionar-se a esse procedimento que pode envolver a percepção de incontrolabilidade.

Objetivo: Determinar la percepción de riesgo en adolescentes relacionado con aborto por embarazos no deseados. Métodos: Estudio observacional descriptivo, transversal y prospectivo, se utilizaron encuestas y entrevistas, así como métodos estadísticos para el procesamiento de la información. El universo estuvo conformado por 354 adolescentes pertenecientes a los consultorios médicos 20, 28 y 30 del Grupo Básico de Trabajo 2 del policlínico Pedro Borrás Astorga, la muestra de 190 adolescentes se encontraron entre las edades de 14 a 18 años. Resultados: Se evidenció una tendencia de los jóvenes a practicar conductas sexuales precoces y riesgosas, lo que favorece el aumento creciente de la práctica del aborto, con insuficientes conocimientos y percepción de riesgo sobre las consecuencias y riesgos de una interrupción de embarazo, donde se encuentran debilitados el rol de los padres y el papel del personal de salud de las áreas donde pertenecen. Conclusiones: Se demostró que el proceso de educación para la salud muestra insuficiencias en cuanto a la creación de programas educativos más creativos que fomentan actividades de promoción y prevención de salud dirigidos a los adolescentes.

Resultados: os indivíduos do Grupo Profissional apresentaram maior ocorrência de rouquidão; maior ocorrência dos hábitos de usar a voz profissional quando está gripado, em posturas corporais e com respiração inadequadas, gritar, e permanecer em local com mofo ou pouca ventilação, fechado e empoeirado, e realizar ensaio em local diferente do local do espetáculo. O hábito de saúde de ingerir bebidas geladas foi maior no Grupo Alunos. O número de sujeitos que não possuem dificuldade em cena e que realizam aquecimento vocal é significantemente maior no Grupo Profissional. O tipo de aquecimento realizado significantemente mais pelo Grupo Profissional foi som de "s", respiração costo-diafragmática, som basal e vogais. Conclusão: constatou-se que ambos os grupos realizam hábitos prejudiciais e estão expostos a ambiente de trabalho inadequado para saúde vocal. Estes dados apontam a necessidade de ações de saúde vocal, a fim de minimizar o risco de alterações vocais nos profissionais e preparar os estudantes para o aumento da demanda vocal.

    Full Text Available Introducción. Según la Organización Mundial de Salud, el cumplimiento del tratamiento de la tuberculosis puede definirse como el grado en que la toma de los medicamentos por parte de un paciente coincide con el tratamiento prescrito. La suma de los pacientes curados y de quienes finalizan el tratamiento (estrategia de observación directa, son indicadores pragmáticos del cumplimiento del tratamiento. Objetivos. Determinar la relación entre el cumplimiento del tratamiento contra la tuberculosis y los factores sociodemográficos, económicos y clínicos, y los relacionados con los medicamentos, tanto de índole objetiva como subjetiva, en pacientes mayores de 18 años. Materiales y métodos. Se hizo un estudio descriptivo transversal de 174 registros de pacientes del programa de control de la tuberculosis y de 15 entrevistas semiestructuradas hechas a los pacientes que no cumplían con el tratamiento durante el periodo comprendido entre junio de 2012 y junio de 2013. Resultados. El cumplimiento del tratamiento en pacientes con tuberculosis pulmonar fue de 94,8 % y fue mayor en los pacientes del régimen contributivo (p=0,035. El incumplimiento del tratamiento fue de 5,2 %. La intolerancia a los medicamentos fue mayor en el grupo de quienes no cumplieron el tratamiento. La falta de apoyo familiar, el abandono del trabajo, el impacto económico y la insatisfacción con la oportunidad de la atención en la institución de salud, fueron factores importantes a la hora de incumplir el tratamiento. Conclusiones. El régimen de afiliación al sistema de salud y la tolerancia a los medicamentos fueron los factores objetivos relacionados con el cumplimiento del tratamiento y, la carga social y económica de la enfermedad, el factor subjetivo.

    Full Text Available En el Uruguay la prevalencia de niños con problemas respiratorios no infecciosos es alta. El tratamiento medicamentoso de esas afecciones puede tener un impacto negativo en la salud bucal. El objetivo del presente estudio fue profundizar en los conocimientos sobre el asma en niños y adolescentes, de los fámacos y dispositivos terapéuticos utilizados y relacionarlos con los eventos adversos observados a nivel bucal. La revisión bibliográfica realizada demuestra que el uso de medicació por vía inhalatoria para las afecciones respiratorias no infecciosas se relaciona con reacciones adversas como la erosión, caries dental, gingivitis, halitosis, candidiasis y xerostomía. El relevamiento realizado en pacientes del Centro Hospitalario Pereira Rossell (2009-2010 mostró una correlación positiva entre los datos de la bibliografía revisada y lo observado en la clínica. Teniendo en cuenta estos antecedentes, es de importancia que el equipo de salud reconozca a la población que utiliza inhaladores como de alto riesgo potencial para el desarrollo de patologías bucales, enfatizando la necesidad de contar con programas educativo-preventivos específicos. La atención para la salud de los pacientes portadores de afecciones respiratorias requiere de un abordaje multidisciplinario

    Full Text Available O forte avanço das obras públicas nos dias atuais se constitui em elemento propulsor da economia nacional, contribuindo para o desenvolvimento da infraestrutura e favorecendo o crescimento do país. Na contramão da história, permanecemos ainda contaminados pela ganância de alguns gestores, que se utilizam indevidamente do poder publico para a satisfação de interesses particulares, quando deveriam administrar buscando a proteção do patrimônio publico e do interesse social, haja vista estar sob a responsabilidade coletiva o pagamento dos tributos que garantem a receita estatal. Os mecanismos de controle surgem como uma das esperanças da sociedade para manter a predominância do interesse publico sobre o particular. No âmbito do controle externo, os Tribunais de Contas começam a ganhar maior notoriedade e respeito social, em razão do trabalho técnico, ético e fundamentado com que avaliam os atos dos gestores concernentes aos dispêndios públicos realizados, em especial no que se refere as obras públicas, em razão das vultosas cifras aplicadas. Neste contexto, o presente trabalho pretende mostrar um panorama dos principais aspectos relacionados a atuação do controle externo na fiscalização das obras públicas.

    Full Text Available El herpesvirus bovino-1 es un virus de distribución mundial causante de graves pérdidas económicas debidas principalmente a la disminución de la eficiencia y en los indicadores de salud y productividad de cualquier hato ganadero infectado. Luego de la infección inicial del tracto respiratorio de los animales, el virus establece un estado de latencia viral en las neuronas sensoriales del ganglio trigémino y en los centros germinales de las tonsilas faríngeas. Periódicamente, el virus es reactivado y excretado en secreciones a través de las cuales puede infectar a otros animales susceptibles. Durante dicho estado de latencia hay disminución dramática de la expresión de genes virales, llevando solo a la expresión de dos transcritos: El RNA codificado por el gen relacionado con latencia (RL y el ORF-E viral. Múltiples estudios demuestran como el RL y el ORF-E están involucrados en la regulación del complejo ciclo de latencia y reactivación de la infección. La presente revisión de literatura se enfocará en describir y analizar los distintos estudios que han llevado a dilucidar el papel jugado por el gen RL y el ORF-E, sus transcritos y sus productos proteicos en el establecimiento, mantenimiento y reactivación de la latencia del HVB-1.

Foram utilizadas 28 fêmeas bovinas, da raça Girolando, com idade entre quatro a dez anos, portadoras de lesões digitais clinicamente caracterizadas como dermatite digital. Os bovinos enfermos foram distribuídos em dois grupos (I e II de quatorze animais. Aqueles pertencentes ao grupo I constituíram o grupo-controle, em que,portanto, não foi utilizada antibioticoterapia. Nas vacas que compuseram o grupo II, aplicaram-se, por via intramuscular,20 mg/kg de peso corporal de oxitetraciclina, em intervalos de 48 horas, até completar quatro aplicações. Ao final de um ano de observação, a maioria das lesões na pele do espaço interdigital entre os talões evoluiu para a forma clínica erosiva e aquelas localizadas nos pontos limítrofes entre apele e o cório coronário dos talões, na parede abaxial do estojo córneo ou no espaço interdigital dorsal, evoluíram para a forma proliferativa. Não houve cura de nenhum animal em ambos os grupos, porém a antibioticoterapia parenteral reduziu a gravidade das lesões. PALAVRAS-CHAVE: Antibioticoterapia, bovinos, dermatite digital, evolução clínica.

Este acontecimiento les llevó a dejar la torre inacabada y a que se marcharan en todas direcciones*; al parecer, esta es una realidad cuando se habla de calidad. En este texto se exponen las definiciones sobre calidad y otros conceptos relacionados, elaborados por autores emblemáticos del tema, incluyendo el impacto que esta noción tiene en el montaje de sistemas de gestión y formalización a través de procesos de certificación. En primera instancia, se aborda el concepto de calidad, incluyendo elementos históricos claves para su comprensión como la calidad en Japón, la calidad total, la calidad y la administración y los antecedentes del sistema de gestión. Luego se realiza una presentación de argumentos, base de la reflexión, que aportan a la necesidad imperiosa de la comprensión de la calidad, como asunto clave debido a su abordaje por presión o por voluntad, hacia un camino de certificación organizacional. Esto con el fin de abogar por la creación de un marco -campo- conceptual fortalecido que hoy se ha convertido en un paradigma, eliminando así la Torre de Babel que se pretende exponer

Los mecanismos fisiopatológicos aún no se comprenden bien, aunque se ha postulado toxicidad directa del etanol y de sus metabolitos, déficits nutricionales y absorción de endotoxinas microbianas intestinales, todo modulado por los patrones de consumo y factores genéticos y ambientales. A nivel individual no puede predecirse con precisión quién tendrá o no problemas. A nivel poblacional para muchos problemas, como varios tipos de cánceres, hepatopatías, lesiones y probablemente conductas de riesgo, como relaciones sexuales sin protección, se suele observar una relación dosis respuesta lineal o exponencial. Para otros, como mortalidad general en mayores de 45 años, enfermedades isquémicas o diabetes mellitus la relación es en forma de J. Su impacto sobre la carga global de enfermedad es enorme, incluso después de descontar los efectos beneficiosos sobre la enfermedad cardiovascular, con diferencias importantes según país, edad, género, posición socioeconómica y otros factores. Buena parte de los daños se relacionan con su capacidad para producir dependencia y con la intoxicación aguda. A menudo genera también consecuencias negativas para otras personas (violencia, incumplimiento de responsabilidades familiares o laborales, molestias que no suelen considerarse al evaluar la carga de enfermedad. El objetivo de este trabajo es describir los principales daños sociales y sanitarios relacionados con el consumo de alcohol y los mecanismos que los generan a partir de fuentes secundarias.

    Full Text Available A partir de la revisión de los principales artículos científicos e informes así como del análisis de algunos datos secundarios, se evaluaron los problemas relacionados con el consumo de alcohol en España entre 1990 y 2011. En 2011 pudo ser atribuibles al alcohol el 10% de la mortalidad total y aproximadamente el 30% de la mortalidad por accidente de tráfico en la población de 15-64 años. En esta misma población al menos el 0,8% padecía trastornos por consumo de alcohol, el 5% adicional podía tener problemas que necesitaban evaluación y aproximadamente el 20% había tenido alguna intoxicación etílica aguda (IEA en el último año. Las IEA supusieron aproximadamente el 0,5-1,1% de las urgencias hospitalarias. Los costes sociales totales del consumo de alcohol podrían representar el 1% del producto interior bruto. La probabilidad de daños relacionados con el consumo de alcohol es bastante mayor en hombres que en mujeres, con una razón hombre/mujer de mortalidad o daños graves relacionados con alcohol de 3/4, situación que apenas ha cambiado en los últimos 20 años. Los daños relacionados con alcohol han seguido una tendencia descendente, excepto la IEA. En el período 1990-2011 la tasa estandarizada de mortalidad relacionada con consumo de alcohol alcohol disminuyó a la mitad. Las grandes lagunas de conocimiento y las incertidumbres sobre los daños poblacionales relacionados con el alcohol en España justifican el apoyo institucional a su investigación y la puesta en marcha de un sistema integral de monitorización.

    Full Text Available Since1949, a great deal of research has been carried out on the radioprotective activity of various chemical substances. Thiol compounds, compounds which contain –SH radical, different classes of pharmacological agents and other compounds such as vitamine C and WR-2721 have been shown to reduce mortality when administered prior to exposure to a lethal dose of radiation. Recently, honey bee venom as well as that of its components melittin and histamine have shown to be valuable in reduction of radiation-induced damage and also provide prophylactic alternative treatment for serious side effects related with radiotherapy. It has been suggested that the radioprotective activity of bee venom components is related with the stimulation of the hematopoetic system.

En el Perú, son un importante problema de salud pública y son causados por una gran variedad de agentes infecciosos. Para la investigación epidemiológica se utiliza una variedad de métodos de tipificación. Una de las herramientas más importantes en la subtipificación molecular de patógenos bacterianos es la técnica de la electroforesis en campo pulsado (PFGE, que es un método altamente resolutivo que permite la discriminación entre diferentes aislamientos bacterianos epidemiológicamente relacionados. El Instituto Nacional de Salud (INS del Perú integra las redes WHO Global Foodborne Infections Network y la Red PulseNet América Latina y Caribe, con quienes comparte los perfiles genéticos de las cepas patógenas aisladas, permitiendo comparar los genotipos de cepas semejantes halladas en diferentes países y reconocer la ocurrencia de brotes epidémicos en la región, fortaleciendo el sistema de vigilancia epidemiológica regional y generando una rápida respuesta conjunta entre países. Se presenta la experiencia de los dos últimos años sobre los avances en la utilización de estas herramientas estratégicas que nos ha permitido caracterizar patrones de genotipo de principales patógenos implicados en ETA a partir de aislamientos recuperados de la red de laboratorios del Perú.Foodborne diseases and other enteric infections often occur as outbreaks and cause morbidity and mortality all over the world.

    Full Text Available O coentro é uma hortaliça amplamente consumida no Brasil como condimento, de grande importância socio-econômica. Problemas relacionados ao baixo vigor de sementes e ao estabelecimento da cultura são uma constante nesta espécie. No presente trabalho 11 lotes comerciais de sementes de coentro das cultivares Verdão, Americano Gigante, Tapacurá, Tabocas, Palmeira e Asteca foram analisados quanto a pureza, germinação, vigor e qualidade sanitária. Em outro estudo, avaliaram-se os efeitos das temperaturas de 15; 20; 25; 30 e 35ºC sobre a germinação das sementes das mesmas cultivares do experimento anterior e mais a cultivar Verdão HV. Houve variação relativamente pequena da germinação entre os lotes e com valores superiores ao padrão nacional para comercialização de sementes. Apenas o lote 1 apresentou pureza abaixo do referido padrão. A qualidade das sementes de coentro comercializadas pelas empresas de sementes no país é, geralmente, satisfatória. Quanto à sanidade, foi detectada a presença de alguns fungos de importância para a cultura do coentro, como Alternaria alternata e Alternaria radicina, com índices de associação elevados. Em um lote, foi detectada a presença de Alternaria dauci. Verificou-se efeito significativo da temperatura, de cultivar e da interação entre a cultivar e temperatura na germinação das sementes. Temperaturas entre 15 e 25ºC proporcionaram maior germinação, enquanto as temperaturas mais elevadas foram prejudiciais. As cultivares 'Verdão HV' e 'Palmeira' germinaram satisfatoriamente a 30ºC. Praticamente não ocorreu germinação a 35ºC para todas as cultivares avaliadas.Coriander is a vegetable crop with large consumption in Brazil, of high social and economic importance.

    Staphylococcus aureus is specie of great medical importance because it is often associated with many infections in humans. This bacterium can cause diseases ranging from simple infections to life-threatening infections such as endocarditis, pneumonia, meningitis, toxic shock syndrome, septicemia, osteomyelitis, among others. S. aureus is the most commonly agent found in infections of the skin and soft tissues, bone infections and bone prostheses. The difficulty in early detection of specific foci caused by bacteria has raised the need to search for new techniques for this purpose. Diagnosis by scintigraphy has advantages over other methods because it is able to identify damage tissues without the need of invasive procedures and is able to perform an early diagnosis even before anatomic changes. Thus, nuclear medicine could contribute to an accurate diagnosis of bacterial infections, since specific radiopharmaceuticals were developed. Aptamers are oligonucleotides that have high affinity and specificity for their molecular targets and are emerging as a new class of molecules for radiopharmaceuticals development. Radiolabeled aptamers specific to the infectious agents, could give a significant contribution to the infection diagnosis by scintigraphy. In this study, aptamers selected to S. aureus were labeled with {sup 99m}Tc and used for the bacteria identification in vitro and in vivo. The aptamers labeled with {sup 32}P and incubated in vitro with S. aureus cells showed high affinity for the bacterial cells when compared with the library of oligonucleotides with random sequences used as control. The aptamers labeled with {sup 99m}Tc also showed affinity for S. aureus cells when compared with the library, but unspecific binding was also verified. The {sup 99m}Tc labelled aptamers were stable in 0.9% saline, plasma of Swiss mice and in excess of cysteine. The in vivo biodistribution studies using Swiss mice with intramuscular infection in the right thigh showed that

    Full Text Available O bullying é um fenômeno devastador podendo vir a afetar a auto-estima e a saúde mental dos adolescentes. Geralmente ocorre quando o adolescente é mais suscetível ou vulnerável às agressões verbais ou morais que lhes causam angústia e dor, principalmente quando ocorrido em ambiente escolar traduzindo-se como uma forma de exclusão social. Pode desencadear alguns problemas de saúde tais como a anorexia, bulimia, depressão, ansiedade e até mesmo o suicídio. A enfermagem, pautada com princípios de prevenir agravos de diversos males, preocupa-se também com esta intercorrência traumática na adolescência. O objetivo deste estudo foi identificar sentimentos que possam estar relacionados com o bullying em adolescentes alunos de 5ª a 8ª séries. Tratou-se de uma pesquisa descritiva de abordagem qualitativa, realizada em uma escola de segmento religioso conveniada com o estado. A coleta de dados ocorreu auxiliada por entrevistas gravadas, posteriormente transcritas e submetidas à análise temática. Os resultados mostraram que os sentimentos relacionados ao fenômeno são múltiplos e variados, sendo categorizados como aspectos de caráter positivo, aspectos de caráter negativo e aspectos de caráter necessário.

    Full Text Available EXPERIÊNCIA E OBJETIVOS: Foram avaliados os riscos da contaminação de propofol 2%, remifentanil e pantoprazol e os efeitos desses agentes in vitro no crescimento de agentes infecciosos comuns em unidades de terapia intensiva. MÉTODOS: Para a detecção do risco de contaminação, foram testados agentes preparados para uso imediato em condições de unidade de terapia intensiva. Também foram investigados os efeitos desses três agentes no crescimento bacteriano. Os agentes foram preparados nas concentrações utilizadas na unidade de terapia intensiva e inoculados com patógenos comuns; em seguida, foram incubados a 4ºC, 22ºC e 36ºC. Foram obtidas subculturas a 0, 2, 4 e 8 h e avaliadas as contagens de colônias. Foram determinados os valores de concentração inibitória mínima para todos os agentes a 4ºC, 22ºC e 36ºC. RESULTADOS: Não foi observado crescimento nos agentes preparados na unidade de terapia intensiva. Propofol tendeu a suportar o crescimento, enquanto que remifentanil inibiu o crescimento bacteriano. O efeito de pantoprazol foi variável, dependendo com a bactéria testada. Nenhum dos agentes demonstrou atividade antibacteriana nas concentrações máximas que podem ser alcançadas no sangue dos pacientes. CONCLUSÃO: Propofol sustenta vigorosamente o crescimento dos microrganismos testados, o que não ocorre com remifentanil e pantoprazol. Portanto, é importante que sejam praticadas técnicas assépticas rígidas na preparação de propofol.

    Full Text Available RESUMO Neste estudo foram analisados os atributos do solo relacionados com variações na produção de frutos da castanheira bem como o estado nutricional da espécie. As árvores foram selecionadas em parcela permanente (Caracaraí, RR e divididas em quatro classes de produção: alta, média, baixa e muito baixa. Em novembro de 2009, amostras de solo e folhas foram coletadas para se avaliar a fertilidade do solo, o número de esporos de fungos micorrízicos arbusculares e o estado nutricional das árvores. Árvores com maior produção de frutos ocorreram associadas a maior teor de Al trocável na camada de 0-20 cm do solo, bem como a menor valor de pH e saturação por bases. A variável discriminante resultante deste estudo não foi considerada como responsável por interferir no potencial produtivo da castanheira-do-brasil, mas serviu como indicativo de que árvores mais produtivas contribuem na remoção de bases trocáveis, favorecendo a acidificação do solo.

    Full Text Available O presente estudo teve como objetivo conhecer a relação e a troca de suporte entre o doente com AIDS e pessoas à sua volta. O estudo está baseado no modelo de comboio das relações sociais que tem como uma de suas características a representação da rede em três círculos concêntricos. Os participantes eram pessoas que estavam internadas e que falaram sobre o suporte relacionado ao cuidado em saúde proporcionado por pessoas próximas, ou seja, que pertenciam ao círculo interno do comboio. A maioria dos participantes descreveu o círculo como sendo composto por no máximo cinco integrantes, sendo que pessoas da família foram as mais citadas. Os profissionais de saúde precisam conhecer o paciente e seu comboio, reconhecendo-os no contexto psicossocial e cultural de forma a favorecer a aceitação da soropositividade, mudanças no estilo de vida, ajuda nos cuidados de saúde e adesão ao tratamento.

    This invention relates to radiodiagnostic agents and more particularly to a composition and method for preparing a highly effective technetium-99m-based bone scanning agent. One deficiency of x-ray examination is the inability of that technique to detect skeletal metastases in their incipient stages. It has been discovered that the methanehydroxydiphosphonate bone mineral-seeking agent is unique in that it provides the dual benefits of sharp radiographic imaging and excellent lesion detection when used with technetium-99m. This agent can also be used with technetium-99m for detecting soft tissue calcification in the manner of the inorganic phosphate radiodiagnostic agents

    2017-09-01

    Full Text Available O diabetes mellitus (DM é uma doença metabólica complexa. Sua etiologia é atribuída a uma combinação entre fatores genéticos, ambientais e de estilo de vida. Contudo, sabe-se que o estresse oxidativo desempenha papel crucial na patogênese do DM, acarretando em disfunção das células β pancreáticas e resistência à insulina. Neste contexto, o fator nuclear eritroide 2 relacionado ao fator 2 (Nrf2 é considerado o regulador mestre da resposta antioxidante do organismo, sendo um mecanismo de importância crítica para a manutenção da homeostase e sobrevivência celular. Todavia, a função do Nrf2 não se limita somente à resposta antioxidante. Ao interagir com outras vias metabólicas, o Nrf2 possui importante papel na regulação do metabolismo, atuando no metabolismo dos lipídios, manutenção da glicemia, resposta inflamatória, entre outros. Entretanto, a exata relação do Nrf2 com outras vias metabólicas ainda não é totalmente conhecida. Contudo, sabe-se que o comprometimento da função do Nrf2 é evidente na fisiopatologia do DM bem como no desenvolvimento de suas complicações clínicas. A ativação do Nrf2 protege contra os danos mediados pelo DM, podendo ser adequada uma intervenção exógena para aumentar a sua atividade.

    Frimer, Jeremy A; Schaefer, Nicola K; Oakes, Harrison

    2014-05-01

    People are motivated to behave selfishly while appearing moral. This tension gives rise to 2 divergently motivated selves. The actor-the watched self-tends to be moral; the agent-the self as executor-tends to be selfish. Three studies present direct evidence of the actor's and agent's distinct motives. To recruit the self-as-actor, we asked people to rate the importance of various goals. To recruit the self-as-agent, we asked people to describe their goals verbally. In Study 1, actors claimed their goals were equally about helping the self and others (viz., moral); agents claimed their goals were primarily about helping the self (viz., selfish). This disparity was evident in both individualist and collectivist cultures, attesting to the universality of the selfish agent. Study 2 compared actors' and agents' motives to those of people role-playing highly prosocial or selfish exemplars. In content (Study 2a) and in the impressions they made on an outside observer (Study 2b), actors' motives were similar to those of the prosocial role-players, whereas agents' motives were similar to those of the selfish role-players. Study 3 accounted for the difference between the actor and agent: Participants claimed that their agent's motives were the more realistic and that their actor's motives were the more idealistic. The selfish agent/moral actor duality may account for why implicit and explicit measures of the same construct diverge, and why feeling watched brings out the better angels of human nature.

    El estigma relacionado con el VIH/SIDA continúa siendo un obstáculo para la prevención primaria y secundaria del VIH. Las consecuencias para las personas que viven con la enfermedad han sido muy documentadas y continúan siendo una gran preocupación para las personas que proveen servicios de salud y para aquellas que investigan el tema. Estas consecuencias son preocupantes cuando el estigma emana de profesionales de la salud porque se puede limitar el acceso a los servicios. Uno de los principales obstáculos para la investigación del estigma relacionado con el VIH en Puerto Rico es la falta de instrumentos cuantitativos para evaluar las manifestaciones del estigma entre profesionales de la salud. El objetivo principal de este estudio fue desarrollar y probar las propiedades psicométricas de una escala sobre el estigma relacionado con el VIH/SIDA culturalmente apropiada para personas que proveen servicios de salud puertorriqueñas y desarrollar una versión corta de la escala que pudiera usarse en escenarios clínicos con tiempo limitado. El instrumento desarrollado estuvo basado en evidencia cualitativa recopilada entre profesionales y estudiantes de profesiones de la salud puertorriqueños/as (n=80) y administrado a una muestra de 421 profesionales de la salud en adiestramiento. La escala contenía 12 dimensiones del estigma relacionado con el VIH/SIDA. El análisis cuantitativo corroboró 11 de ellas, teniendo como resultado un instrumento con validez y confiabilidad satisfactoria. Estas dimensiones, a su vez, fueron subcomponentes de un factor de estigma general superior. PMID:20333258

A pesquisa limitou-se a artigos originais realizados com seres humanos, em língua inglesa, excluindo-se a população adulta e idosa, assim como os artigos de revisão, comunicação breve, cartas e editoriais. Síntese dos dados: Após análise dos estudos por dois revisores, de forma independente, segundo os critérios de elegibilidade, permaneceram na revisão sete artigos, publicados entre 2012 e 2016. Foram incluídos estudos de delineamento transversal, prospectivo, coorte e caso-controle. A importância da adipocina quemerina nos fatores de risco para doenças cardiovasculares é demonstrada por meio de sua associação com obesidade e diabetes melito, assim como com parâmetros clínicos, antropométricos e bioquímicos. Entretanto, a força da evidência dos estudos é relativamente baixa, em função da heterogeneidade das publicações, destacando-se como limitações o número reduzido das amostras e sua ausência de representatividade, a falta de padronização dos métodos de dosagem, o delineamento transversal de grande parte dos estudos e a impossibilidade de extrapolação dos resultados. Conclusões: A desregulação da quemerina provocada pelo aumento de tecido adiposo pode contribuir para o aparecimento de doenças cardiovasculares, sugerindo que tal adipocina tem papel relevante na identificação precoce de indivíduos em risco.

    Full Text Available O objetivo do artigo foi evidenciar os referenciais teóricos relacionados a qualidade do serviço logístico, tendo como metodologia o levantamento bibliográfico utilizando livros, artigos, dissertações e teses, relacionadas ao assunto. Foram relacionadas as definições de logísticas. No que se refere aos componentes do serviço foi ressaltado que estes fazem parte de processo logístico desde o pedido até a entrega do produto. Já a qualidade do serviço logístico assegura que é difícil de quantificar, pois é uma função de diferentes percepções dos clientes ao longo do tempo, do processo de medição e da análise dos dados recolhidos. Destaca-se ainda que os principais elementos do serviço logístico que ocorrem na transação são relativos à entrega (questões de tempo, frequência, confiabilidade e qualidade, ao próprio ciclo do pedido (questões de tempo e confiabilidade, ao cumprimento do pedido (pedidos completos entregues dentro do prazo e à comunicação (recebimento de informações, como por exemplo, sobre a posição do pedido e previsão da data de entrega. Com relação ao serviço ao cliente, o foco e a meta dos autores remetem ao atendimento ao cliente, concluindo-se que um programa de serviço ao cliente deve identificar e priorizar todas as atividades necessárias para atender aos requisitos logísticos dos clientes, tão bem ou melhor que os concorrentes. O assunto é extenso e o artigo não pretendeu elencar todos os escritores que tecem sobre o assunto, mas relacionar os autores que são comumente citados nos estudos sobre o tema.

  6. Factores y mecanismos relacionados con la dormancia en tubérculos de papa. Una revisión

    2010-08-01

    Full Text Available Los tubérculos de la papa (Solanum tuberosum L., al momento
    de la cosecha y por un tiempo determinado, se encuentran en
    estado dormante. La dormancia se induce con el inicio de la
    tuberización y se define como un período en el cual no ocurre
    ningún crecimiento visible de los brotes. Las hormonas vegetales
    están involucradas en todas las fases de progresión de
    la dormancia. Si bien el ácido abscísico (ABA y el etileno son
    necesarios para su inducción, sólo el primero se requiere para
    su mantenimiento. Los niveles de ABA se incrementan durante
    la formación de los tubérculos, se mantienen constantes durante
    la dormancia y disminuyen con el crecimiento activo de los
    brotes. Un incremento en los niveles del ácido giberélico (AG
    es necesario para inducir la formación del tubérculo, mientras
    que una sensibilidad mayor a las citoquininas es determinante
    para la pérdida de la dormancia. Cambios en los contenidos de
    ácido indol acético (AIA y AG , están relacionados con la regulación
    del crecimiento del brote una vez se rompe la dormancia.
    Se ha comprobado que un factor importante, que contribuye
    tanto a la inducción de la tuberización como a la pérdida de la
    dormancia, es el flujo simplástico que controla la asignación de
    azúcares, el cual se inicia con un meristemo apical dormante
    aislado simplásticamente. La pérdida de dormancia se asocia
    con la conexión simplástica del meristemo del brote con la red
    de floema del tubérculo, y con una descarga simplástica en la
    región de la yema, todo lo cual favorece el crecimiento activo
    de los nuevos brotes.

    Full Text Available A resiliência, como uma variável de desfecho, tem sido largamente negligenciada no campo terapêutico. Nosso objetivo foi investigar os efeitos da terapia cognitivo-comportamental (TCC nos marcadores neurobiológicos de resiliência em pacientes com transtorno de estresse pós-traumático (TEPT. Nesta pesquisa experimental de caso único, foram acessadas variáveis fisiológicas (frequência cardíaca, frequência respiratória, tônus vagal cardíaco, balanço simpático e condutância da pele e neuroendócrinas (cortisol e de-hidroepiandrosterona - DHEA e medidas psicométricas de autorrelato (afeto negativo, resiliência, sintomas de TEPT, depressão, ansiedade e apoio social. Foram medidas as respostas fisiológicas, neuroendócrinas e psicométricas em repouso antes e após quatro meses de TCC. O paciente era um homem de 45 anos que sofreu dois assaltos com arma de fogo e não respondeu adequadamente ao tratamento farmacológico com paroxetina. A TCC levou a uma redução da frequência cardíaca, frequência respiratória, balanço simpático, condutância da pele e cortisol, bem como a um aumento no tônus vagal e DHEA. Além disso, a TCC promoveu redução na pontuação dos sintomas de TEPT, depressão, ansiedade e afeto negativo e aumento da pontuação de resiliência e apoio social. Nossos dados sugerem que a TCC aumenta os fatores relacionados à resiliência (DHEA, tônus vagal, autorrelato de resiliência e apoio social. Isso não é somente "antipatológico", mas também pode ser considerado "pró-bem-estar". Adicionalmente, nossos resultados mostram a relevância da investigação dos efeitos do tratamento psicológico em múltiplos sistemas neurobiológicos no mesmo paciente com TEPT, visando desvendar as bases neurobiológicas dos fatores de resiliência.

    Full Text Available El acelerado crecimiento que ha experimentado la población costarricense en las últimas décadas y la proyección de la misma, ha sido motivo de preocupación y estudio por parte de especialistas en el campo y autoridades nacionales. El desarrollo económico y social de la nación costarricense ha dejado saldos muy importantes de pobreza que ha sido comentado en otro trabajo (1. Los Índices de desarrollo económico, que han sido muy altos, si se proyectan, no van a satisfacer las necesidades de todo orden del sector mayoritario de la población. Hay razones importantes para creer que si la población y la economía continúan desarrollándose al ritmo actual, las diferencias económicas y sociales entre los estratos altos y los estrados bajos de la sociedad costarricense serán más profundas a la vez que, cuantitativamente, la población marginada será aún mayor en las décadas del 80 y 90, que en la actualidad. Por otro lado, conceptos modernos bien definidos de la salud materno infantil, así como de tipo social y educacional, han creado una corriente favorable que impulsa la Planificación Familiar como proceso conveniente en la sociedad moderna. Entendida ésta como el conjunto de conocimientos psicobiosociales que los padres deben poseer para decidir sobre el número de hijos y la frecuencia del nacimiento de éstos, con el propósito de fortalecer la unidad familiar y garantizar la paternidad responsable. El gobierno de la República y varios grupos privados han mantenido una activa acción en el campo de la Planificación Familiar en los últimos años. Todo parece indicar que el futuro estos programas se intensificarán. Por estas razones, se creyó conveniente investigar en recientes encuestas realizadas, algunos aspectos relacionados con la Planificación Familiar, que pudieran mejorar la eficiencia de esos programas, o por lo menos, contribuir al conocimiento de las características de algunas actitudes importantes del

    Full Text Available La distrofia miotónica (DM es la distrofia muscular más común en adultos. Diversos factores pueden explicar la retención crónica de CO2. La selección de pacientes, diferentes estadios evolutivos y formas de evaluación, pueden explicar los resultados disímiles al respecto. Nuestros objetivos fueron caracterizar la función respiratoria y analizar los factores relacionados con la retención crónica de CO2 en la DM. Se incluyeron 27 pacientes ambulatorios consecutivos, estables clínicamente y se los agrupó como normocápnicos e hipercápnicos (PaCO2 ≥ 43 mm Hg. Se determinaron capacidad vital forzada (FVC, presiones estáticas máximas, tiempo de apnea voluntaria, escala de Epworth y gases arteriales. La quimiosensibilidad al CO2 se evaluó mediante la reinhalación de CO2 (método de Read. La pendiente ∆P0.1/∆PCO2 expresa la quimiosensibilidad al CO2. El 59.3% tenían hipercapnia. La FVC y la fuerza muscular respiratoria fueron normales o mostraron disminución leve a moderada, sin diferencias significativas en ambos grupos. La inadecuada respuesta al CO2 (pendientes ∆P0.1/∆PCO2 bajas (< 0.1 cmH2O/mm Hg o planas se asoció con hipercapnia (p < 0.005 y ésta significó un riesgo 11.6 veces mayor de inadecuada respuesta al CO2. El grupo con pendiente ∆P0.1/∆PCO2 baja-plana mostró mayor PaCO2 (p = 0.0017 y tiempo de apnea voluntaria más prolongado (p = 0.002. Concluimos que, en nuestros pacientes con DM, la hipercapnia crónica se asoció a la presencia de anomalías del control central de la respiración. Estos resultados permiten explicar los informes previos que describen la llamativa ocurrencia de insuficiencia respiratoria postoperatoria y las dificultades en el proceso de desvinculación de asistencia ventilatoria mecánica en estos pacientes.

    The use of chemotherapeutic agents for the treatment of cancer dates back to the late 19th century, but the modern era of chemotherapy drugs was ushered in during the 1940's with the development of the polyfunctional alkylating agent. Since then, numerous classes of drugs have evolved and the combined use of antineoplastic agents with other treatment modalities such as radiation or heat, remains a large relatively unexplored area. This approach, combining local hyperthermia with chemotherapy agents affords a measure of targeting and selective toxicity not previously available for drugs. In this paper, the effects of adriamycin, bleomycin and cis-platinum are examined. The adjuvant use of heat may also reverse the resistance of hypoxic cells noted for some chemotherapy agents

    .OBJETIVO: Caracterizar as infecções, em pacientes com Síndrome Nefrótica Idiopática. PACIENTES E MÉTODOS: Foram analisados, os prontuários de 92 crianças e adolescentes com Síndrome Nefrótica Idiopática . Os tipos de infecções foram agrupados em: Infecções de Vias Aéreas Superiores , Pnemonia, Infecções Cutâneas, Peritonite, Diarréia, Infecção do Trato Urinário, Herpes Vírus e Outros. Os pacientes foram divididos, em dois grupos: Grupo I (córtico-sensíveis-n=75, com quatro subgrupos; IA (episódio único-n=10; IB (recidivantes infreqüentes-n=5; IC (recidivantes freqüentes-n=14 e ID (córtico-dependentes n=46; e Grupo II (córtico-resistentes-n=17. Comparou-se a densidade de incidência de infecções nos períodos com proteinúria negativa e nefrótica. No período com proteinúria nefrótica, comparou-se a densidade de incidência de infecções dos grupos e subgrupos entre si. Da mesma forma, no período com proteinúria negativa. RESULTADO: A análise revelou maior densidade de incidência de infecções, no período com proteinúria nefrótica, em todos os grupos e subgrupos, com exceção do subgrupo IA. No período com proteinúria nefrótica, os subgrupos IC, ID e o grupo II, apresentaram maior densidade de incidência de infecções, quando comparados ao subgrupo IA. No período com proteinúria negativa, não houve diferença na densidade de incidência de infecções entre os grupos e subgrupos. As Infecções de Vias Aéreas Superiores foram os processos infecciosos mais freqüentes. CONCLUSÃO: O estado nefrótico, manifesto através de recidivas freqüentes, dependência ou resistência aos corticosteróides, conferiu ao pacientes com Síndrome Nefrótica Idiopática , maior susceptibilidade à infecções. O resultado deste estudo reforça que a melhor prevenção anti-infecciosa nesta doença é o controle do estado nefrótico.

Comorbidades psiquiátricas e físicas, aumento do risco de suicídio, maior utilização de serviços de saúde e prejuízo na esfera social/profissional aumentam significativamente a carga e custos relacionados à doença. OBJETIVOS: Revisar aspectos clínicos, de carga da doença e conseqüentes desfechos financeiros do TAB. MÉTODOS: Pesquisa de base de dados MEDLINE/PubMed utilizando os termos bipolar disorder, epidemiology, burden of disease, comorbidity, cost of illness, outcomes e financial consequences, publicados entre 1980 e 2006. RESULTADOS: O TAB apresenta alta comorbidade com outros transtornos, o que agrava seu prognóstico e eleva os custos com os serviços de saúde. Os indivíduos com TAB apresentam mais fatores de risco cardiovascular e, conseqüentemente, maior risco de morte por evento cardíaco. O atraso e o erro diagnóstico no TAB elevam consideravelmente a carga e os custos da doença. CONCLUSÕES: As comorbidades, o risco de suicídio, o prejuízo social/profissional e a baixa adesão ao tratamento contribuem para a alta carga e os custos associados à doença. A pesquisa de comorbidades pode ajudar os médicos a ajustarem suas estratégias de tratamento, considerando cuidadosamente todos os fatores de risco e custos associados, fatores estes que devem ser levados em conta também pelos profissionais que trabalham com gestão de saúde, tanto no setor privado quanto público.BACKGROUND: Bipolar disorder (BD is a recurrent, chronic and severe disease.

  1. "O que vêm da terra não faz mal": relatos de problemas relacionados ao uso de plantas medicinais por raizeiros de Diadema/SP

    Directory of Open Access Journals (Sweden)

    Juliana Lanini

    Full Text Available A crença de que medicamentos à base de plantas são isentos de riscos à saúde faz parte da bagagem cultural da população afeita ao seu uso: "o que vêm da terra não faz mal". No entanto, o potencial tóxico, as características específicas do usuário, a possibilidade de contaminação e a falta de regulamentação constituem fatores de risco para a ocorrência de reações adversas, intoxicações e outras complicações decorrentes de seu uso. Foram realizadas entrevistas semi-estruturadas junto a 20 raizeiros (vendedores de ervas "in natura" na cidade de Diadema/SP. Foram relatados 40 casos de problemas relacionados ao uso de 22 espécies de plantas medicinais. As espécies mais citadas foram Luffa operculata - buchinha (7 casos, Senna alexandrina - sene (4 casos e Paullinia cupana - guaraná (3 casos. Dentre os sinais e sintomas relatados, os mais freqüentes foram relacionados ao sistema nervoso central, problemas gastrointestinais e cardiovasculares. Os entrevistados também relataram um caso de aborto relacionado ao uso de S. alexandrina e três casos de óbito após a ingestão do chá do fruto de L. operculata. O caráter "natural" das plantas medicinais não é sinônimo de ausência de riscos para a população usuária. É necessária a implantação de políticas de fitofarmacovigilância eficientes, a fim de tornar o consumo mais racional e, deste modo, minimizar os riscos à população usuária.

    We propose an agent-based framework for assisting and simplifying person-to-person communication for information gathering tasks. As an example, we focus on locating experts for any specified topic. In our approach, the informal person-to-person networks that exist within an organization are used to {open_quotes}referral chain{close_quotes} requests for expertise. User-agents help automate this process. The agents generate referrals by analyzing records of e-mail communication patterns. Simulation results show that the higher responsiveness of an agent-based system can be effectively traded for the higher accuracy of a completely manual approach. Furthermore, preliminary experience with a group of users on a prototype system has shown that useful automatic referrals can be found in practice. Our experience with actual users has also shown that privacy concerns are central to the successful deployment of personal agents: an advanced agent-based system will therefore need to reason about issues involving trust and authority.

    Full Text Available OBJETIVO: Estimar e comparar a prevalência dos eventos relacionados à gravidez (engravidar, baixo peso de nascimento, parto prematuro, aborto espontâneo, natimortalidade, malformações congênitas e gemelaridade em populações exposta e não-exposta aos contaminantes ambientais na região do estuário de Santos e São Vicente. MÉTODOS: O estudo fez parte de um amplo projeto financiado pelo CNPq, que teve como objetivo estimar os efeitos à saúde associados à exposição aos contaminantes ambientais entre os moradores da Baixada Santista. O estudo transversal avaliou dois bairros do município de São Vicente, próximos a uma área contaminada, e um bairro no município de Bertioga, área controle. Para a obtenção dos dados foi aplicado um questionário estruturado e pré-testado em 236 domicílios em São Vicente e 251 domicílios em Bertioga. Para avaliar associações entre a área e as variáveis qualitativas utilizouse o teste qui-quadrado ou teste exato de Fisher; para avaliar as diferenças entre as variáveis, o teste t de Student ou o teste de comparação de duas proporções, e adotado nível de significância de 5%. RESULTADOS: Houve associação significativa entre morar em Bertioga (p = 0,01 e o número de gestações ocorridas nos últimos cinco anos. Em São Vicente, 64 (28,3% mulheres em idade fértil engravidaram, enquanto em Bertioga foram 109 (38,8%. Não houve associações estatísticas significativas nas áreas com os demais desfechos da gravidez avaliados. CONCLUSÕES: As prevalências e as razões de chances prevalentes de baixo peso ao nascer, nascimentos prematuros e abortos espontâneos foram maiores nas áreas contaminadas, sem associações significativas. A evidência do estudo de diminuição do número de gestações na área contaminada reforça a necessidade de aprofundamento de estudos na região do estuário de Santos e São Vicente.OBJECTIVE: Estimate and compare prevalence of events related to

  20. Monitoring volatile anaesthetic agents

    International Nuclear Information System (INIS)

    2000-01-01

    Full text: The methods that have been used for monitoring volatile anaesthetic agents depend on some physical property such as Density, Refractometry, Mass, Solubility, Raman scattering, or Infra-red absorption. Today, refractometry and infra-red techniques are the most common. Refractometry is used for the calibration of vaporizers. All anaesthetic agents increase the refractive index of the carrier gas. Provided the mixture is known then the refractive change measures the concentration of the volatile anaesthetic agent. Raman Scattering is when energy hits a molecule a very small fraction of the energy is absorbed and re-emitted at one or more lower frequencies. The shift in frequency is a function of the chemical bonds and is a fingerprint of the substance irradiated. Electromagnetic (Infra-red) has been the commonest method of detection of volatile agents. Most systems use a subtractive system, i.e. the agent in the sampling cell absorbed some of the infrared energy and the photo-detector therefore received less energy. A different approach is where the absorbed energy is converted into a pressure change and detected as sound (Acoustic monitor). This gives a more stable zero reference. More recently, the detector systems have used multiple narrow-band wavelengths in the infrared bands and by shape matching or matrix computing specific agent identification is achieved and the concentration calculated. In the early Datex AS3 monitors, a spectral sweep across the 3 micron infrared band was used to create spectral fingerprints. The recently released AS3 monitors use a different system with five very narrow band filters in the 8-10 micron region. The transmission through each of these filters is a value in a matrix which is solved by a micro computer to identify the agent and its concentration. These monitors can assist in improving the safety and efficiency of our anaesthetics but do not ensure that the patient is completely anaesthetized. Copyright (2000

    Full Text Available Esse artigo visa revisar os resultados encontrados na literatura a respeito dos diversos fatores relacionados com a resposta hormonal aguda e crônica ao treinamento de força. Foi observado que existe uma estreita relação entre a treinabilidade de indivíduos submetidos ao treinamento de força e os níveis circulantes de testosterona nesses sujeitos. Além disso, outros parâmetros hormonais, tais como as razões entre a testosterona e sua proteína carreadora e entre a testosterona com o cortisol, também foram relacionados com a capacidade de aumento de força. Diversos fatores ligados à sessão de treino, além das características da população investigada, influenciam a resposta hormonal aguda e crônica ao treinamento. Entre esses fatores, o volume e a intensidade são as principais variáveis ligadas à magnitude dessa resposta. A determinação de quais fatores possam estar estreitamente relacionados com a resposta hormonal ao treinamento de força pode ser importante para o estabelecimento de uma sessão de treino e uma periodização que otimizem o ambiente anabólico determinado pelas concentrações de testosterona e cortisol, e, dessa forma, maximizar os ajustes neuromusculares decorrentes desse tipo de treinamento.This study aims to review the results found in the literature concerning a variety of factors related to the acute and chronic hormonal response to strength training. It has been observed that there is a close relationship between the trainability of individuals submitted to strength training and the circulating testosterone levels in these subjects. Moreover, other hormonal parameters, such as the ratios between testosterone and its binding protein and between testosterone and cortisol, were also related to the ability to increase strength. Besides the characteristics of the population investigated, several factors associated with the training session affect the acute and chronic hormonal response to training

Este artículo tiene por objeto publicar la compilación de los documentos arqueológicos y textuales conocidos, relacionados con el Visir Amen-Hotep, Huy, hasta el momento en que, en el año 2009, se inició por el Instituto de Estudios del Antiguo Egipto de Madrid la exploración y excavación sistemática de la tumba nº -28- , construida por orden del Visir Amen-Hotep, Huy, en la necrópolis de Asasif (Luxor Occidental.The documents and monuments connected with the vizier Amen-Hotep, Huy, who was Vizier of the South, at the end of the reign of Amen-Hotep III (XVIIIth. dynasty c.1358 - 1353 BC, are very scarce, compared with referrals to other courtiers in the same period. The main reason for this darkness is, without doubt, the fact of having been persecuted his memory, and his monuments, destroyed . This article aims to publish the compilation of known archaeolgical and textual documents, in relation with the Vizier Amen-Hotep, Huy, before 2009, when the Instituto de Estudios del Antiguo Egipto of Madrid started the systematic exploration and excavation in the tomb No. 28-, built by order of this high royal functionary, in the necropolis of Asasif (Luxor West Bank.

    Anesthesia may often be considered as a high-risk procedure and anaphylaxis remains a major cause of concern for anesthetists who routinely administer many potentially allergenic agents. Neuromuscular blocking agents, latex and antibiotics are the substances involved in most of the reported reactions. Besides these three agents, a wide variety of substances may cause an anaphylactic reaction during anesthesia. Basically all the administered drugs or substances may be potential causes of anaphylaxis. Among them, those reported the most in literature include hypnotics, opioids, local anesthetics, colloids, dye, Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), Iodinated Contrast Media (ICM), antiseptics, aprotinin, ethylene oxyde and formaldehyde, and protamine and heparins. No premedication can effectively prevent an allergic reaction and a systematic preoperative screening is not justified for all patients; nevertheless, an allergy specialist should evaluate those patients with a history of anesthesia-related allergy. Patients must be fully informed of investigation results, and advised to provide a detailed report prior to future anesthesia.

    There are many chemical respiratory agents suitable for use by terrorists. They are the oldest chemical agents used and have caused the most casualties throughout the 20th century. Many are available in large quantities for industrial use and are susceptible to potential sabotage. This paper will concentrate on respiratory agents that are readily available and have the potential to cause a large number of casualties and panic. These agents have a lower rate of lethality when compared to other chemical agents but could produce many casualties that may overwhelm the emergency medical system.

    2007-01-01

    Toxorhynchites is an unusual and interesting genus of large, non-biting mosquitoes. In spite of their size, they are--like many species of mosquitoes--completely harmless to man. The larvae are predaceous on other mosquitoes and aquatic organisms that inhabit both natural and artificial containers. Because this habitat is the source of several medically important species of mosquitoes, there is warrant for evaluating the potential of Toxorhynchites as a biological control agent under various conditions. Toxorhynchites is not seen as a panacea for the control of all container-inhabiting mosquitoes. However, it has demonstrated practical potential in certain restricted but important situations.

    2013-02-01

    Hungarian physicist Dennis Gabor won the Pulitzer Prize for his 1947 introduction of basic holographic principles, but it was not until the invention of the laser in 1960 that research scientists, physicians, technologists and the general public began to seriously consider the interdisciplinary potentiality of holography. Questions around whether and when Three-Dimensional (3-D) images and systems would impact American entertainment and the arts would be answered before educators, instructional designers and students would discover how much Three-Dimensional Hologram Technology (3DHT) would affect teaching practices and learning environments. In the following International Symposium on Display Holograms (ISDH) poster presentation, the author features a traditional board game as well as a reflection hologram to illustrate conventional and evolving Three-Dimensional representations and technology for education. Using elements from the American children's toy Operation® (Hasbro, 2005) as well as a reflection hologram of a human brain (Ko, 1998), this poster design highlights the pedagogical effects of 3-D images, games and systems on learning science. As teaching agents, holograms can be considered substitutes for real objects, (human beings, organs, and animated characters) as well as agents (pedagogical, avatars, reflective) in various learning environments using many systems (direct, emergent, augmented reality) and electronic tools (cellphones, computers, tablets, television). In order to understand the particular importance of utilizing holography in school, clinical and public settings, the author identifies advantages and benefits of using 3-D images and technology as instructional tools.

    An elevated proportion of high cardiovascular risk patients do not achieve the therapeutic c-LDL goals. This owes to physicians' inappropriate or insufficient use of cholesterol lowering medications or to patients' bad tolerance or therapeutic compliance. Another cause is an insufficient efficacy of current cholesterol lowering drugs including statins and ezetimibe. In addition, proprotein convertase subtilisin kexin type 9 inhibitors are a new cholesterol lowering medications showing safety and high efficacy to reduce c-LDL in numerous already performed or underway clinical trials, potentially allowing an optimal control of hypercholesterolemia in most patients. Agents inhibiting apolipoprotein B synthesis and microsomal transfer protein are also providing a new potential to decrease cholesterol in patients with severe hypercholesterolemia and in particular in homozygote familial hypercholesterolemia. Last, cholesteryl ester transfer protein inhibitors have shown powerful effects on c-HDL and c-LDL, although their efficacy in cardiovascular prevention and safety has not been demonstrated yet. We provide in this article an overview of the main characteristics of therapeutic agents for hypercholesterolemia, which have been recently approved or in an advanced research stage.

Nesse sentido, a busca por novas estratégias de ensino e de avaliação da aprendizagem faz-se necessária. No entanto, percebe-se que muitos tradutores/intérpretes de língua de sinais (TILS possuem dificuldades para interpretar os conceitos científicos, muitas vezes distantes da sua formação. O objetivo deste trabalho é fornecer aos professores e TILS, das séries iniciais do Ensino Fundamental, subsídios para o ensino dos conceitos relacionados à astronomia. Para isso, foi realizada uma pesquisa de levantamento dos sinais relacionados à astronomia, indicados pelos Parâmetros Curriculares Nacionais (PCNs, presentes em dois principais dicionários de Libras em circulação no país e em um dicionário especializado em Astronomia. Por meio desse levantamento, foram analisados 49 conceitos e suas definições, fazendo uma releitura e indicando uma definição mais adequada para os TILS e professores. Constatouse que as definições de alguns sinais presentes nos dicionários possuem distorções, redundâncias e conteúdos que demandam uma formação mais específica para sua abordagem. A releitura permitiu a construção de uma redação mais simples e ofereceu a possibilidade da sugestão de conceitos ainda não constituídos na Libras.

    While an agent generator is generating an intelligent agent, it can also evaluate the data processing platform on which it is executing, in order to assess a risk factor associated with operation of the agent generator on the data processing platform. The agent generator can retrieve from a location external to the data processing platform an open site that is configurable by the user, and load the open site into an agent substrate, thereby creating a development agent with code development capabilities. While an intelligent agent is executing a functional program on a data processing platform, it can also evaluate the data processing platform to assess a risk factor associated with performing the data processing function on the data processing platform.

    Full Text Available Mushrooms have been known for their nutritional and culinary values and used as medicines and tonics by humans for ages. In modern terms, they can be considered as functional foods which can provide health benefits beyond the traditional nutrients. There are monographs that cover the medicinal and healing properties of some individual traditional mushrooms. There has been a recent upsurge of interest in mushrooms not only as a health food which is rich in protein but also as a source of biologically active compounds of medicinal value which include complementary medicine/dietary supplements for anticancer, antiviral, hepatoprotective, immunopotentiating and hypocholesterolemic agents. However the mechanisms of the various health benefits of mushrooms to humans still require intensive investigation, especially given the emergence of new evidence of their health benefits. In the present paper the medicinal potential of mushrooms is being discussed.

    Mixing various amounts of chemotherapeutic agents such as cisplatinum, 5-fluorouracil, mitomycin-C, and adriamycin with polymers such as poly-d, 1-lactide, ethylhydroxyethylcellulose, and polycaprolactone, several kinds of microcapsules were made. Among them, microcapsule made from ethylhydroxyethylcellulose showed best yield. Under light microscopy, the capsules were observed as particles with refractive properties. For the basic toxicity test, intraarterial administration of cisplatinum was done in 6 adult mongrel dogs. Follow-up angiography was accomplished in 2 wk intervals for 6 wks. Despite no significant difference in the histopathological examination between the embolized and normal kidneys, follow-up angiogram showed atrophy of renal cortex and diminished numbers of arterial branches in the embolized kidneys. In order to identify the structural properties of microcapsules, and to determine the drug content and the rate of release, further experiment is thought to be necessary. (Author)

    Full Text Available La logística humanitaria ha tomado un gran impulso como área de estudio, esto a causa del aumento en la frecuencia de desastres naturales a nivel global. Dentro de esta área existe un problema en particular poco tratado en la literatura, el cual se encuentra relacionado con las ayudas recibidas luego del acontecimiento de un desastre. Este problema puede presentarse como un exceso en la oferta de suministros, la llegada de productos no necesitados o el abasto de bienes vencidos. La falta de coordinación entre los actores involucrados en las operaciones de ayuda puede concebirse como una de las causas de la problemática, denominada convergencia de materiales. Este artículo se centra en la problemática de la convergencia de materiales en logística humanitaria. Se presenta una aproximación teórica computacional del problema utilizando modelado basado en agentes, donde se caracterizan los flujos, los actores y sus interrelaciones, para medir el impacto en el desempeño logístico. Seguido de la simulación se realiza un análisis experimental de los resultados con tres diferentes configuraciones del sistema.

    Full Text Available In order to measure and classify odors, Quartz Crystal Microbalance (QCM can be used. In the present study, seven QCM sensors and three different odors are used. The system has been developed as a virtual organization of agents using an agent platform called PANGEA (Platform for Automatic coNstruction of orGanizations of intElligent Agents. This is a platform for developing open multi-agent systems, specifically those including organizational aspects. The main reason for the use of agents is the scalability of the platform, i.e. the way in which it models the services. The system models functionalities as services inside the agents, or as Service Oriented Approach (SOA architecture compliant services using Web Services. This way the adaptation of the odor classification systems with new algorithms, tools and classification techniques is allowed.

  13. Agent-based enterprise integration

    1998-12-01

    The authors are developing and deploying software agents in an enterprise information architecture such that the agents manage enterprise resources and facilitate user interaction with these resources. The enterprise agents are built on top of a robust software architecture for data exchange and tool integration across heterogeneous hardware and software. The resulting distributed multi-agent system serves as a method of enhancing enterprises in the following ways: providing users with knowledge about enterprise resources and applications; accessing the dynamically changing enterprise; locating enterprise applications and services; and improving search capabilities for applications and data. Furthermore, agents can access non-agents (i.e., databases and tools) through the enterprise framework. The ultimate target of the effort is the user; they are attempting to increase user productivity in the enterprise. This paper describes their design and early implementation and discusses the planned future work.

    Full Text Available The main focus of this paper is the supervision of enforcement agents conducted by enforcement courts. Law on Enforcement and Security recognizes three levels of control of enforcement agents. Certain monitoring powers are delegated to the Ministry of Justice and to Chamber of Enforcement Agents. However, for parties and other participants to enforcement proceedings control of enforcement agents implemented by enforcement courts seems to be the most important one. The strongest powers of enforcement agents are related to the special procedure for collection of claims for utilities and other similar services (exclusive competence of enforcement agents and for carrying out the enforcement (if enforcement creditor has requested it. When it comes to special procedure for collection of claims for utilities and other similar services objection can be used in order to control legality of decisions rendered by enforcements agents. However, many procedural issues related to the objection procedure remain unsolved. Motion for correction of irregularities is the only legal remedy that can be used when enforcement is being carried out by enforcement agents. This legal remedy cannot be considered an effective one in the sense of Article 13 European Convention for Protection of Human Rights and Fundamental Liberties. The new proposed Law on Enforcement and Security expected to come into force on July 1, 2016, will delegate the exclusive competence for carrying out the enforcement to enforcement agents (except cases related to family relations and reinstatement, but it will not improve the court supervision of their work.

    An easily prepared radiolabeled gastrointestinal scanning agent is described. Technetium-99m has ideal characteristics for imaging the upper and lower GI tract and determining stomach emptying and intestinal transit time when used with an insoluble particulate material. For example, crystalline and amorphous calcium phosphate particles can be effectively labeled in a one-step process using sup(99m)TcO 4 and SnCl 2 . These labeled particles have insignificant mass and when administered orally pass through the GI tract unchanged, without affecting the handling and density of the intestinal contents. Visualization of the esophageal entry into the stomach, the greater and lesser curvatures of the stomach, ejection into the duodenum, and rates of passage through the upper and lower GI tract are obtained. The slurry of sup(99m)TC particulate can be given rectally by enema. Good images of the cecum and the ascending, transverse, and descending colon are obtained. Mucosal folds and the splenic and hepatic flexures are visualized. The resilience of the large intestine is also readily visualized by pneumocolonographic techniques. (author)

  4. Incorporating BDI Agents into Human-Agent Decision Making Research

    Science.gov (United States)

    Kamphorst, Bart; van Wissen, Arlette; Dignum, Virginia

    Artificial agents, people, institutes and societies all have the ability to make decisions. Decision making as a research area therefore involves a broad spectrum of sciences, ranging from Artificial Intelligence to economics to psychology. The Colored Trails (CT) framework is designed to aid researchers in all fields in examining decision making processes. It is developed both to study interaction between multiple actors (humans or software agents) in a dynamic environment, and to study and model the decision making of these actors. However, agents in the current implementation of CT lack the explanatory power to help understand the reasoning processes involved in decision making. The BDI paradigm that has been proposed in the agent research area to describe rational agents, enables the specification of agents that reason in abstract concepts such as beliefs, goals, plans and events. In this paper, we present CTAPL: an extension to CT that allows BDI software agents that are written in the practical agent programming language 2APL to reason about and interact with a CT environment.

    Software agents are increasingly being used to represent humans in online auctions. Such agents have the advantages of being able to systematically monitor a wide variety of auctions and then make rapid decisions about what bids to place in what auctions. They can do this continuously and repetitively without losing concentration. To provide a means of evaluating and comparing (benchmarking) research methods in this area the trading agent competition (TAC) was established. This paper describes the design, of TACtic. Our agent uses multi behavioral techniques at the heart of its decision making to make bidding decisions in the face of uncertainty, to make predictions about the likely outcomes of auctions, and to alter the agent's bidding strategy in response to the prevailing market conditions.

    Full Text Available Os sistemas de preparo afetam a estrutura do solo e podem influenciar o armazenamento de água disponível para as plantas. O objetivo deste estudo foi avaliar o efeito de longo prazo (17 anos dos sistemas de preparo convencional (PC, preparo reduzido (PR e semeadura direta (SD sobre os atributos físicos relacionados ao armazenamento e disponibilidade de água de um Argissolo Vermelho com textura média, em Eldorado do Sul, RS. Amostras de solo (0-2,5, 2,5-7,5, 7,5-12,5, 12,5-17,5cm foram coletadas numa seqüência ervilhaca/milho. Adicionalmente, amostrou-se uma área sob campo nativo (CN, adjacente à área experimental, como referência à condição natural do solo. O solo em SD apresentou maiores teores de carbono orgânico (CO na camada superficial e maiores valores de resistência ao penetrômetro em profundidade, em relação ao solo em preparo convencional. Os sistemas de preparo não se diferenciaram quanto ao seu efeito na macro e microporosidade do solo, contudo o revolvimento no PC aumentou a condutividade hidráulica saturada em profundidade. Não se verificou nenhuma restrição física ao desenvolvimento radicular sob os diferentes sistemas de preparo, o que foi comprovado pelos valores de densidade (1,35 a 1,65 Mg m-3, macroporosidade (0,09 a 0,20 m³ m-3 e resistência ao penetrômetro (0,25 a 0,75 MPa. Do ponto de vista hídrico, as curvas de retenção e o volume de água disponível (AD = 10 kPa (capacidade de campo - 1.500 kPa (ponto de murcha permanente, não foram influenciados pelos sistemas de preparo, sendo o baixo volume de água disponível (0,05 a 0,09 m³ m-3 relacionado à textura desse solo. Nesse caso, o aumento da taxa de infiltração e a diminuição da evaporação da água decorrente da manutenção dos resíduos vegetais sobre o solo nos sistemas de preparo reduzido e semeadura direta, podem contribuir para uma maior disponibilidade hídrica na fase inicial do estabelecimento das culturas nesses sistemas

Objective: to identify factors associated with in-hospital mortality in patients with acute myocardial infarction admitted to the Coronary Intensive Care Unit of Cienfuegos in 2010. Methods: we conducted a case series study, which included 241 patients with acute myocardial infarction admitted to the Coronary Intensive Care Unit of the Dr. Gustavo Aldereguía Lima General University Hospital of Cienfuegos in 2010. The variables analyzed were age, sex, personal medical history, type of acute myocardial infarction (according to electrocardiogram and topographic location, heart rate and blood pressure at admission, classification of heart failure according to Killip Kimball, creatinine, glucose, total cholesterol, triglycerides, CPK-MB, and cardiovascular adverse events during their hospital stay. Results: the average age of the patients was 65,6 years old, with male predominance. High blood pressure, smoking and previous myocardial infarction were the most relevant antecedents. Patients with no heart failure and preserved ejection fraction predominated. Most frequent cardiovascular adverse events were post-infarction angina, ventricular arrhythmias and cardiogenic shock. Conclusions: we found significant association with mortality and old age (> 70 years, tachycardia, blood glucose ≥ 7 mmol / l at admission, and the presentation of ventricular arrhythmias and cardiogenic shock during in-hospital evolution.Fundamento: la identificación de los factores relacionados con la mortalidad en el infarto agudo del miocardio representa un eslabón primordial en la evaluación inicial de los pacientes.

Los líquenes epífitos han sido ampliamente utilizados como bioindicadores de la contaminación atmosférica, debido a que obtienen la mayor parte de nutrientes del aire, lo que los hace muy sensibles a los cambios derivados de la contaminación. Se evaluó la calidad del aire en siete parques de la ciudad, donde se registró la presencia y la cobertura de líquenes epífitos sobre árboles de Salix humboldtiana. Se determinaron los niveles de contaminación con el Índice de Pureza Atmosférica (IPA y se establecieron diferencias en la composición de especies de los parques mediante análisis de escalamiento multidimensional no métrico (NMDS y PERMANOVA. Nuestros resultados mostraron la existencia de una mayor calidad ambiental en las zonas norte y sur de la ciudad, mientras que se observa un patrón contrario para los parques ubicados en la zona central de la urbe, muy relacionados con un aumento de tráfico vehicular. Las comunidades de líquenes epífitos resultaron ser excelentes indicadores biológicos para detectar la contaminación del aire en la ciudad.

  16. Overview of shoreline cleaning agents

    International Nuclear Information System (INIS)

    Clayton, J.

    1992-01-01

    Chemical cleaning agents may be used to promote release of stranded oil from shorelines for reasons including biological sensitivity of indigenous fauna and flora to the oil, amenity considerations of the shoreline, or concern about refloating of the oil and subsequent stranding on adjacent shorelines. While use of chemical cleaning agents may be appropriate under proper toxic responses in circumstances, certain limitations should be recognized. The potential for toxic responses in indigenous fauna and flora to the cleaning agents must be considered. Enhanced penetration of oil into permeable shorelines following treatment with chemical cleaning agents also is not desirable. However, if conditions related to toxicity and substrate permeability are determined to be acceptable, the use of chemical cleaning agents for treatment of stranded oil can be considered. Chemical agents for cleaning oiled shorelines can be grouped into three categories: (1) non-surfactant-based solvents, (2) chemical dispersants, and (3) formulations especially designed to release stranded oil from shoreline substrates (i.e., shoreline-cleaning-agents). Depending on the specific circumstances present on an oiled shoreline, it is generally desirable that chemical agents used for cleaning will release oil from shoreline substrate(s) to surface waters. Recovery of the oil can then be accomplished by mechanical procedures such as booming and skimming operations

    McBurney, Peter; Parsons, Simon

    The rise of the Internet and the growth of distributed computing have led to a major paradigm shift in software engineering and computer science. Until recently, the notion of computation has been variously construed as numerical calculation, as information processing, or as intelligent symbol analysis, but increasingly, it is now viewed as distributed cognition and interaction between intelligent entities [60]. This new view has major implications for the conceptualization, design, engineering and control of software systems, most profoundly expressed in the concept of systems of intelligent software agents, or multi-agent systems [99]. Agents are software entities with control over their own execution; the design of such agents, and of multi-agent systems of them, presents major research and software engineering challenges to computer scientists.

  19. A Verification Logic for GOAL Agents

    Science.gov (United States)

    Hindriks, K. V.

    Although there has been a growing body of literature on verification of agents programs, it has been difficult to design a verification logic for agent programs that fully characterizes such programs and to connect agent programs to agent theory. The challenge is to define an agent programming language that defines a computational framework but also allows for a logical characterization useful for verification. The agent programming language GOAL has been originally designed to connect agent programming to agent theory and we present additional results here that GOAL agents can be fully represented by a logical theory. GOAL agents can thus be said to execute the corresponding logical theory.

    Clinical chemoprevention trials of more than 30 agents and agent combinations are now in progress or being planned. The most advanced agents are well known and are in large Phase III chemoprevention intervention trials or epidemiological studies. These drugs include several retinoids [e.g., retinol, retinyl palmitate, all-trans-retinoic acid, and 13-cis-retinoic acid], calcium, Beta carotene, vitamin E, tamoxifen, and finasteride. Other newer agents are currently being evaluated in or being considered for Phase II and early Phase III chemoprevention trials. Prominent in this group are all-trans-N-(4-hydroxy phenyl)retinamide (4-HPR) (alone and in combination with tamoxifen), 2-difluoromethylornithine (DFMO), nonsteroidal antiinflammatory drugs (aspirin, piroxicam, sulindac), oltipraz, and dehydroepiandrostenedione (DHEA). A third group is new agents showing chemopreventive activity in animal models, epidemiological studies, or in pilot clinical intervention studies. They are now in preclinical toxicology testing or Phase I safety and pharmacokinetics trials preparatory to chemoprevention efficacy trials. These agents include S-allyl-l-cysteine, curcumin, DHEA analog 8354 (fluasterone), genistein, ibuprofen, indole-3-carbinol, perillyl alcohol, phenethyl isothiocyanate, 9-cis-retinoic acid, sulindac sulfone, tea extracts, ursodiol, vitamin D analogs, and p-xylyl selenocyanate. A new generation of agents and agent combinations will soon enter clinical chemoprevention studies based primarily on promising chemopreventive activity in animal models and in mechanistic studies. Among these agents are more efficacious analogs of known chemopreventive drugs including novel carotenoids (e.g., alpha-carotene and lutein). Also included are safer analogs which retain the chemopreventive efficacy of the parent drug such as vitamin D3 analogs. Other agents of high interest are aromatase inhibitors (e.g., (+)-vorozole), and protease inhibitors (e.g., Bowman-Birk soybean trypsin

    Full Text Available INTRODUCTION: Sporotrichosis is the most common subcutaneous mycosis observed in Brazil and it is generally consequent to a little trauma caused by vegetal particles or spines which inoculate the fungi in the subcutaneous area. Although sporotrichosis had been frequently mentioned with armadillo hunting this form has not been widely reported in Brazil until now. In this study we report ten cases of sporotrichosis evolving the armadillo's hunting diagnosed in some towns located in the central and west regions of Rio Grande do Sul State. METHODS: The cases were established based on clinical and classic mycological laboratorial techniques. The susceptibility tests were conducted by microdilution technique according to M38-A2 CLSI documents. RESULTS: Ten cases of sporotrichosis associated with armadillo hunting detected in the State of Rio Grande do Sul were diagnosed by mycological methods. The susceptibility tests of Sporothrix schenckii isolates to antifungal agents itraconazole, ketoconazole and terbinafine showed that all the isolates were susceptible. CONCLUSIONS: The paper discusses some cultural aspects related to hunting of this wild animal as well as possible causes of this unexpected occurrence in southern Brazil.INTRODUÇÃO: A esporotricose constitui-se na micose subcutânea mais frequentemente observada e, na maioria dos casos, a infecção é decorrente de pequenos traumas envolvendo fragmentos vegetais ou espinhos que inoculam o fungo no tecido subcutâneo. Embora frequentemente relacionada a caça a tatus, esta ocorrência tem sido raramente relatada no Brasil. Neste estudo relatamos dez casos envolvendo esta prática, observados em várias cidades das regiões centro e oeste do Estado do Rio Grande do Sul. MÉTODOS: o diagnóstico clínico foi confirmado pelos métodos clássicos de cultura em ágar Mycobiotic, identificação micromorfológica seguida de reversão a fase leveduriforme em ágar BHI.

    Epigenetic changes resulting from aberrant methylation patterns are a recurrent observation in hematologic malignancies. Hypomethylating agents have a well-established role in the management of patients with high-risk myelodysplastic syndrome or acute myeloid leukemia. In addition to the direct effects of hypomethylating agents on cancer cells, there are several lines of evidence indicating a role for immune-mediated anti-tumor benefits from hypomethylating therapy. Areas covered: We reviewed the clinical and basic science literature for the effects of hypomethylating agents, including the most commonly utilized therapeutics azacitidine and decitabine, on immune cell subsets. We summarized the effects of hypomethylating agents on the frequency and function of natural killer cells, T cells, and dendritic cells. In particular, we highlight the effects of hypomethylating agents on expression of immune checkpoint inhibitors, leukemia-associated antigens, and endogenous retroviral elements. Expert commentary: In vitro and ex vivo studies indicate mixed effects on the function of natural killer, dendritic cells and T cells following treatment with hypomethylating agents. Clinical correlates of immune function have suggested that hypomethylating agents have immunomodulatory functions with the potential to synergize with immune checkpoint therapy for the treatment of hematologic malignancy, and has become an active area of clinical research.

    Using Affymetrix oligonucleotide GeneChip analysis, we previously found that, upon exposure to the simple alkylating agent methylmethane sulfonate, the transcript levels for about one third of the Saccharomyces cerevisiae genome (∼2,000 transcripts) are induced or repressed during the first hour or two after exposure. In order to determine whether the responsiveness of these genes has any relevance to the protection of cells against alkylating agents we have undertaken several follow-up studies. First, we explored the specificity of this global transcriptional response to MMS by measuring the global response of S. cerevisiae to a broad range of agents that are known to induce DNA damage. We found that each agent produced a very different mRNA transcript profile, even though the exposure doses produced similar levels of toxicity. We also found that the selection of genes that respond to MMS is highly dependent upon what cell cycle phase the cells are in at the time of exposure. Computational clustering analysis of the dataset derived from a large number of exposures identified several promoter motifs that are likely to control some of the regulons that comprise this large set of genes that are responsive to DNA damaging agents. However, it should be noted that these agents damage cellular components other than DNA, and that the responsiveness of each gene need not be in response to DNA damage per se. We have also begun to study the response of other organisms to alkylating agents, and these include E. coli, cultured mouse and human cells, and mice. Finally, we have developed a high throughput phenotypic screening method to interrogate the role of all non-essential S. cerevisiae genes (about 4,800) in protecting S. cerevisiae against the deleterious effects of alkylating agents; we have termed this analysis 'genomic phenotyping'. This study has uncovered a plethora of new pathways that play a role in the recovery of eukaryotic cells after exposure to toxic

Foi desenvolvida em duas instituições de abrigo localizadas no sul do Brasil, nos meses de junho e julho de 2008. Para produção dos dados, utilizou-se o Método Criativo Sensível desenvolvendo-se duas dinâmicas de criatividade e sensibilidade, brincar em cena e corpo saber, com quatro crianças, com idades entre 8 e 11 anos. Os dados foram submetidos à análise de discurso francesa. Os resultados apontaram como fatores associados à institucionalização: problemas mentais e uso abusivo de álcool da mãe e agressão. Acredita-se que o reconhecimento dos fatores associados à violência intrafamiliar possibilita atuar preventivamente, minimizando os efeitos deletérios que esta pode causar aos integrantes da família. Assim, o cuidado não deve se resumir somente às crianças vítimas de violência, mas necessita envolver o cuidado às famílias, abrangendo vítimas e agressores.Investigación cualitativa que ha objetivado comprender los factores relacionados a la institucionalización de niños víctimas de violencia intrafamiliar.

    Full Text Available La epidemia de obesidad es un fenómeno universal que no parece reconocer límites ni geográficos ni sociodemográficos. Las investigaciones sobre los factores responsables de la epidemia se centran sobre algunas de las condiciones sociales y económicas que imperan en las sociedades actuales. El presente artículo muestra la situación de la obesidad en España y la tendencia de una serie de factores potencialmente relacionados. El incremento en la prevalencia de obesidad se acompañó de importantes cambios en el patrón de alimentación de la población a pesar de una tendencia estabilizada en la ingesta calórica total y de grasas. Diversos indicadores indirectos muestran la tendencia sedentaria de la población, a pesar de que un mayor porcentaje de la población declara realizar ejercicio físico en su tiempo libre. Los factores dependientes del gasto energético parecen tan o más importantes que los derivados del ingreso. Para explicar la situación paradójica de los distintos indicadores de sedentarismo se sugiere la hipótesis de un aumento del "stock de tiempo libre" en las sociedades actuales.The obesity epidemic is a global phenomenon that does not respect geographic or socio-demographic boundaries. Thus, research on factors related to the obesity epidemic has focused on social and economic characteristics of modern societies. This article discusses obesity in Spain and trends in several associated factors. Together with the increase in the prevalence of obesity, important changes in the population's dietary pattern have been observed, although total energy and fat intake appear to be stable. According to several indirect indicators, sedentary behavior predominates, although the percentage of the population reporting some leisure exercise is increasing. An increase in the amount of leisure time in modern societies is suggested as an explanation for this paradox. Factors related to energy expenditure could be as important as

    Full Text Available Resumo No Brasil, a história das secas é marcada por seguidas tragédias sociais e sanitárias, com estimativas de 3 milhões de óbitos entre o início do século XIX e o final do século XX e o registro de quase 32 mil eventos e mais de 96 milhões de afetados entre 1991 e 2010. Apesar de no Brasil a seca ser um desastre histórico, não encontramos, desde a expedição científica de Arthur Neiva e Belisário Penna em 1912 nas zonas flageladas pela seca, muitas pesquisas sobre a relação seca e saúde no Brasil. O objetivo deste trabalho é apresentar uma revisão dos artigos científicos sobre a relação seca e saúde coletiva. Foram utilizadas as bases de dados PubMed, Portal Preparação e Respostas a Desastres da BVS e Portal de Periódicos da Capes, utilizando-se os descritoresdrought and health no título e resumo, selecionando-se somente artigos em inglês e espanhol com relação direta com os temas em saúde. Dentre os efeitos sobre a saúde encontrados, destacam-se os relacionados à desnutrição e deficiências nutricionais, saúde mental, qualidade das águas e do ar, além do comprometimento da qualidade e do acesso aos serviços de saúde. Considerando-se as tendências de episódios de seca mais intensos e frequentes e de escassez de água até 2030, torna-se urgente ampliar as pesquisas sobre o tema e revisões da literatura.

OBJETIVO: Descrever o padrão de combinação dos fatores de risco relacionados ao diagnóstico de SM em militares da Marinha do Brasil e identificar eventuais variáveis associadas à presença da referida síndrome nessa população. MÉTODOS: Estudo transversal envolvendo 1.383 homens (18-62 anos lotados nas organizações militares da Grande Natal-RN. O critério utilizado para diagnóstico de SM foi o proposto pela International Diabetes Association. A razão entre a prevalência observada e a esperada e os respectivos intervalos de confiança foram utilizados para identificar as combinações de fatores de risco que excediam o esperado para a população. A análise de regressão logística foi utilizada para identificar variáveis associadas à SM. RESULTADOS: A prevalência de SM foi de 17,6%. Aproximadamente um terço dos militares apresentou dois ou mais fatores de risco para SM. Todas as combinações específicas dos fatores de risco para SM que excederam a prevalência esperada apresentaram a obesidade abdominal como um de seus componentes. Nas análises ajustadas, idade, tabagismo e nível de atividade física mantiveram-se associados à SM. CONCLUSÃO: Nossos achados reforçam a constante presença da obesidade abdominal no fenótipo da SM. Além disso, nossos dados também suportam a ideia de que idade, tabagismo e baixo nível de atividade física são variáveis independentes para a ocorrência de SM.

    Full Text Available OBJETIVO: Analisar a prevalência e os fatores de risco relacionados ao uso indevido de drogas entre estudantes de uma escola pública de primeiro e segundo graus. MÉTODOS: Foi realizado estudo descritivo transversal, utilizando, como instrumento de pesquisa, um questionário anônimo, padronizado e amplamente testado no Brasil para levantamento do uso de drogas. A população estudada foi constituída de 478 estudantes de escola pública de primeiro e segundo graus, de Florianópolis, SC. Os questionários foram aplicados por estudantes universitários devidamente treinados. Entre os estudantes pesquisados, 43% e 32% foram de faixa etária de 13 a 15 anos e de 16 a 18 anos, respectivamente, com predomínio de classes socioeconômicas mais altas. RESULTADOS: A prevalência de uso de maconha na vida (19,9%, solventes (18,2%, anfetamínicos (8,4% e álcool (86,8% foi elevada em Florianópolis, comparada a outras capitais da região Sul e à média brasileira. Notou-se elevado e freqüente uso (seis ou mais vezes por mês de álcool (24,2%, maconha (4,9%, solventes (2,5% e anfetamínicos (2,3%. Os fatores demográficos relacionados ao uso de drogas na vida foram idade, sexo, classe socioeconômica e vida junto aos pais. A chance de garotas usarem remédios para emagrecer ou ficarem acordadas foi o dobro da chance de garotos e, quanto ao uso de tranqüilizantes, quase o triplo. Os garotos tinham um risco quase duas vezes maior de uso de solvente do que as garotas. A classe socioeconômica alta foi associada a um risco duas vezes maior do uso de álcool do que a classe baixa. O risco de uso de cigarro e maconha na vida foi 84% e 67% maior, respectivamente, para alunos cujos pais estavam separados. CONCLUSÃO: Constatou-se alta prevalência de uso de várias drogas entre os alunos de primeiro e segundo graus.OBJECTIVE: To assess prevalence and risk factors associated with drug abuse among public elementary and high school students in the southern

MÉTODOS: Los datos se reunieron en 2001 y 2002 mediante la Encuesta Nacional de Epidemiologia Psiquiátrica de México. El muestreo se llevó a cabo por estratificación probabilística de seis regiones geográficas del país en un proceso polietápico que comprendió, en orden sucesivo, áreas censuales, manzanas urbanas, grupos de domicilios, e individuos. Los datos se ponderaron teniendo en cuenta la probabilidad de selección y el porcentaje de respuesta. La información se recogió mediante una versión computadorizada de la edición de la Entrevista Diagnóstica Internacional Compuesta usada para la Encuesta Mundial de Salud Mental. El porcentaje de respuesta ponderado para individuos fue de 76,6. RESULTADOS: En general, 2,3% de la población declaró haber incurrido en el consumo ilícito de drogas durante los 12 meses anteriores a la encuesta; la marijuana y la cocaína fueron las sustancias consumidas con mayor frecuencia. La baja escolaridad mostró una asociación significativa con el consumo, el abuso y la dependencia de drogas. El consumo de cualquier tipo de droga tuvo una frecuencia significativamente mayor en personas pertenecientes al grupo de edad más joven (18-29 años, en varones, o en habitantes de la parte noroccidental del país. De la muestra en general, 1,4% había abusado o dependido de las drogas en algún momento de la vida, y ello ocurrió con mucha más frecuencia en varones (2,9% que en mujeres (0,2%.

    This paper describes the design and implementation of the Mobile Objects and Agents (MOA) project at the Open Group Research Institute. MOA was designed to support migration, communication and control of agents. It was implemented on top of the Java Virtual Machine, without any modifications to it. The initial project goals were to support communication across agent migration, as a means for collaborative work; and to provide extensive resource control, as a basic support for countering denial of service attacks. In the course of the project we added two further goals: compliance with the Java Beans component model, which provides for additional configurability and customization of agent system and agent applications; and interoperability, which allows cooperation with other agent systems. This paper analyses the architecture of MOA, in particular the support for mobility, naming and locating, communication, and resource management. Object and component models of MOA are discussed and some implementation details described. We summarize the lessons learned while developing and implementing MOA and compare it with related work.

    Pregnancies in diabetic women are associated with increased risk of spontaneous abortion, congenital malformations, preeclampsia, preterm labor, macrosomia, shoulder dystocia, and cesarean section. Advances in antepartum cares and strict adherence to dietary and insulin regimens have been shown to significantly reduce the rate of maternal morbidity as well as perinatal morbidity and mortality. Historically, reports of potential fetal teratogenicity and hypoglycemic effects on the fetus contraindicated the use of oral hypoglycemic agents in pregnancies complicated with either type II diabetes mellitus (DM) or gestational diabetes mellitus (GDM). Recently, physicians increasingly prescribe newer generations of oral hypoglycemic agents to treat GDM and type II DM to pregnant patients. This review addresses the safety, current recommendations, and controversies surrounding use of the available oral hypoglycemic agents during pregnancy. Obstetricians & Gynecologists, Family Physicians After completion of this article, the reader should be able to describe the mechanisms of actions of the various oral hypoglycemic agents, to list the known side effects of these agents, and to summarize the data on the use of these agents during pregnancy.

    Full Text Available This paper presents a document representation strategy and a bio-inspired algorithm to cluster multilingual collections of documents in the field of economics and business. The proposed approach allows the user to identify groups of related economics documents written in Spanish and English using techniques inspired on clustering and sorting behaviours observed in some types of ants. In order to obtain a language independent vector representation of each document two multilingual resources are used: an economic glossary and a thesaurus. Each document is represented using four feature vectors: words, proper names, economic terms in the glossary and thesaurus descriptors. The proper name identification, word extraction and lemmatization are performed using specific tools. The tf-idf scheme is used to measure the importance of each feature in the document, and a convex linear combination of angular separations between feature vectors is used as similarity measure of documents. The paper shows experimental results of the application of the proposed algorithm in a Spanish-English corpus of research papers in economics and management areas. The results demonstrate the usefulness and effectiveness of the ant clustering algorithm and the proposed representation scheme.Este artículo presenta una estrategia de representación documental y un algoritmo bioinspirado para realizar procesos de agrupamiento en colecciones multilingües de documentos en las áreas de la economía y la empresa.

O exercício profissional obriga que cirurgiões-dentistas utilizem na execução das tarefas os membros superiores e estruturas adjacentes, freqüentemente com repetitividade de um mesmo padrão de movimento, compressão mecânica das estruturas localizadas na região, assumindo posturas incorretas, utilizando força excessiva e ainda, na maioria dos casos, trabalhando sob pressão temporal. O presente estudo utilizou o método epidemiológico transversal para buscar evidências da existência da relação entre as tarefas executadas pelo cirurgião-dentista e as LERs/DORTs. Os estudos empíricos revelaram presença de associação estatisticamente significante entre os dois sexos e as patologias. O sexo feminino apresenta mais lesões que o masculino.

    Full Text Available A produção brasileira de cerâmica continua em seu processo de expansão. O tamanho do mercado nordestino e os custos de transportes associados ao baixo valor agregado dos revestimentos cerâmicos estimularam um movimento de desconcentração regional da produção, uma vez que a implantação de unidades produtivas no Nordeste passou a fazer parte da estratégia competitiva de algumas empresas. O presente trabalho busca mostrar os principais autos de infração relacionados aos empreendimentos de Cerâmica no Estado do Rio Grande do Norte pelo Instituto Brasileiro do Meio Ambiente e dos Recursos Renováveis do RN - IBAMA/RN, órgão ambiental fiscalizador no Estado, no período de 01/01/2002 a 04/10/2005. O levantamento de dados foi realizado através do acesso a Sistemas operados pelo IBAMA/RN, que informou o número de indústrias cadastradas no Rio Grande do Norte, o número de infrações, entre outras. Foram verificadas 140 indústrias cadastradas no Estado, distribuídas em 24 municípios. O alto número de indústrias do setor pode ser decorrente da centralização da atividade como alternativa econômica visto que a região apresenta condições ambientais que prejudicam seu potencial produtivo. O levantamento dos dados revelou que as principais infrações eram receber, armazenar ou transportar produto florestal sem cobertura de ATPF (Autorização de Transporte de Produtos Florestais e funcionar sem prévio registro no IBAMA. A atuação dos órgãos governamentais foi constatada como de fundamental importância para a diminuição do número de autos de infração das indústrias de cerâmica, referente ao período avaliado. A substituição da matriz energética, nas indústrias de cerâmica, de lenha para gás natural é a alternativa ideal no combate à poluição e de outras formas impactantes.

Los programas de detección precoz con imágenes y endoscopia oral han permitido el diagnóstico en estadios iniciales e incremento de la supervivencia, aunque el 60 % de los pacientes se diagnostican en estadio III o IV, y la sobrevida global a los 5 años es de 5 a 15 %. El objetivo de esta revisión fue identificar los factores pronósticos relacionados con el cáncer gástrico dependientes del paciente, del propio tumor, y del tratamiento, que puedan incidir en la aparición de la recurrencia tumoral tras la cirugía y ayuden a considerar terapéuticas adecuadas. Las variables biológicas del enfermo no muestran asociación significativa con el pronóstico del cáncer gástrico, a diferencia del grado de invasión de la pared, el compromiso ganglionar y los factores biológicos tumorales. La cirugía es el único tratamiento potencialmente curativo, pero resulta insuficiente para muchos enfermos, a pesar de las linfadenectomías ampliadas. Alrededor de 80 % de los operados presentará una recurrencia con un pronóstico fatal. La quimioterapia, la radioterapia y la inmunoterapia no han cambiado aún notoriamente la historia natural de la enfermedad. El seguimiento posoperatorio no puede ser sistematizado debido a la baja sensibilidad de los métodos para detectar el patrón de recurrencia, así como la ausencia de su tratamiento efectivo. La identificación de los factores pronósticos del cáncer gástrico permite estratificar a los pacientes y seleccionar diferentes tratamientos en un intento de incrementar la supervivencia.The gastric cancer is the second more frequent malignant tumor prevailing in western countries but mainly in the Asiatic ones.

    2018-03-01

    One of the essential aspect in biological agents is dynamic stability. This aspect, called homeostasis, is widely discussed in ethology, neuroscience and during the early stages of artificial intelligence. Ashby's homeostats are general-purpose learning machines for stabilizing essential variables of the agent in the face of general environments. However, despite their generality, the original homeostats couldn't be scaled because they searched their parameters randomly. In this paper, first we re-define the objective of homeostats as the maximization of a multi-step survival probability from the view point of sequential decision theory and probabilistic theory. Then we show that this optimization problem can be treated by using reinforcement learning algorithms with special agent architectures and theoretically-derived intrinsic reward functions. Finally we empirically demonstrate that agents with our architecture automatically learn to survive in a given environment, including environments with visual stimuli. Our survival agents can learn to eat food, avoid poison and stabilize essential variables through theoretically-derived single intrinsic reward formulations.

    Wanscher, Jørgen

    This thesis investigates the possibilities in applying Operations Research (OR) to autonomous vehicular traffic. The explicit difference to most other research today is that we presume that an agent is present in every vehicle - hence Agent Based Individual Traffic guidance (ABIT). The next...... evolutionary step for the in-vehicle route planners is the introduction of two-way communication. We presume that the agent is capable of exactly this. Based on this presumption we discuss the possibilities and define a taxonomy and use this to discuss the ABIT system. Based on a set of scenarios we conclude...... that the system can be divided into two separate constituents. The immediate dispersion, which is used for small areas and quick response, and the individual alleviation, which considers the longer distance decision support. Both of these require intrinsicate models and cost functions which at the beginning...

    This report summarizes the findings for phase one of the agent review and discusses the review methods and results. The phase one review identified a short list of agent systems that would prove most useful in the service architecture of an information management, analysis, and retrieval system. Reviewers evaluated open-source and commercial multi-agent systems and scored them based upon viability, uniqueness, ease of development, ease of deployment, and ease of integration with other products. Based on these criteria, reviewers identified the ten most appropriate systems. The report also mentions several systems that reviewers deemed noteworthy for the ideas they implement, even if those systems are not the best choices for information management purposes.

  18. Dual Rationality and Deliberative Agents

    Science.gov (United States)

    Debenham, John; Sierra, Carles

    Human agents deliberate using models based on reason for only a minute proportion of the decisions that they make. In stark contrast, the deliberation of artificial agents is heavily dominated by formal models based on reason such as game theory, decision theory and logic—despite that fact that formal reasoning will not necessarily lead to superior real-world decisions. Further the Nobel Laureate Friedrich Hayek warns us of the ‘fatal conceit’ in controlling deliberative systems using models based on reason as the particular model chosen will then shape the system’s future and either impede, or eventually destroy, the subtle evolutionary processes that are an integral part of human systems and institutions, and are crucial to their evolution and long-term survival. We describe an architecture for artificial agents that is founded on Hayek’s two rationalities and supports the two forms of deliberation used by mankind.

    Purpose: To increase the processing performance even when the iodine content is great and obtain solidification products of excellent durability. Constitution: The solidifying agent mainly comprises waterhardenable material, calcium aluminate (CA), gypsum, ultrafine powder and high performance water reducer. As the water hardenable material, mixed cement incorporated with portland cement, for example, is used. CA with CAO/Al 2 O 3 molar ratio of about 1.5 - 4 is used. Gypsum dihydrate is used as the gypsum in an amount of about 2 to 19 parts by weight based on 29 to 93 parts by weight of water-hardenable materials. The average grain size of the ultrafine powder is lower by about one digit than that of water-hardenable material, CA and gypsum and, for example, silica dust is used. The high performance water reducing agent is a surface active agent, for example, mainly comprising naphthalene sulfonate, etc. (Yoshio, Y.)

  1. Thyroid Dysfunction from Antineoplastic Agents

    Larsen, P. Reed; Marqusee, Ellen

    2011-01-01

    Unlike cytotoxic agents that indiscriminately affect rapidly dividing cells, newer antineoplastic agents such as targeted therapies and immunotherapies are associated with thyroid dysfunction. These include tyrosine kinase inhibitors, bexarotene, radioiodine-based cancer therapies, denileukin diftitox, alemtuzumab, interferon-α, interleukin-2, ipilimumab, tremelimumab, thalidomide, and lenalidomide. Primary hypothyroidism is the most common side effect, although thyrotoxicosis and effects on thyroid-stimulating hormone secretion and thyroid hormone metabolism have also been described. Most agents cause thyroid dysfunction in 20%–50% of patients, although some have even higher rates. Despite this, physicians may overlook drug-induced thyroid dysfunction because of the complexity of the clinical picture in the cancer patient. Symptoms of hypothyroidism, such as fatigue, weakness, depression, memory loss, cold intolerance, and cardiovascular effects, may be incorrectly attributed to the primary disease or to the antineoplastic agent. Underdiagnosis of thyroid dysfunction can have important consequences for cancer patient management. At a minimum, the symptoms will adversely affect the patient’s quality of life. Alternatively, such symptoms can lead to dose reductions of potentially life-saving therapies. Hypothyroidism can also alter the kinetics and clearance of medications, which may lead to undesirable side effects. Thyrotoxicosis can be mistaken for sepsis or a nonendocrinologic drug side effect. In some patients, thyroid disease may indicate a higher likelihood of tumor response to the agent. Both hypothyroidism and thyrotoxicosis are easily diagnosed with inexpensive and specific tests. In many patients, particularly those with hypothyroidism, the treatment is straightforward. We therefore recommend routine testing for thyroid abnormalities in patients receiving these antineoplastic agents. PMID:22010182

    An important trend for the future of health technology will be the increasing use of intelligent agent software for medical applications. As the complexity of situations faced by both patients and health care providers grows, conventional interfaces that rely on users to manually transfer data and manually perform each problem-solving step, won't be able to keep up. This article describes how software agents that incorporate learning, personalization, proactivity, context-sensitivity and collaboration will lead to a new generation of medical applications that will streamline user interfaces and enable more sophisticated communication and problem-solving.

    2004-04-01

    Autonomous sensor manager agents are presented as an algorithm to perform sensor management within a multisensor fusion network. The design of the hybrid ant system/particle swarm agents is described in detail with some insight into their performance. Although the algorithm is designed for the general sensor management problem, a simulation example involving 2 radar systems is presented. Algorithmic parameters are determined by the size of the region covered by the sensor network, the number of sensors, and the number of parameters to be selected. With straight forward modifications, this algorithm can be adapted for most sensor management problems.

O tratamento envolve mastectomia, quimioterapia e radioterapia, que, pelos seus efeitos físicos, podem comprometer em variados graus a auto-estima, a imagem corporal e a identidade feminina daquelas que recebem o diagnóstico da doença. Além disso, em nossa sociedade o câncer adquiriu significados relacionados a culpa, punição, deterioração, dor e morte, agravando o sofrimento psicológico das doentes. Neste sentido, este artigo tem o objetivo de levantar alguns pontos de reflexão no que se relaciona aos significados culturais da doença e do significado do seio enquanto ícone da identidade feminina. Partimos do princípio de que enriquecer a compreensão dos aspectos que influenciam o sofrimento da mulher com câncer de mama contribui para que os profissionais de saúde, principalmente os de saúde mental, possam assisti-la de maneira mais eficiente e abrangente.En Brasil y en el mundo la incidencia del cáncer de mama está en acenso.

El tratamiento envuelve mastectomía, quimioterapia y radioterapia que, por sus efectos físicos, pueden comprometer en variados grados la autoestima, la imagen corporal y la identidad femenina de aquellas mujeres que reciben el diagnóstico de la enfermedad. Además de eso, en nuestra sociedad el cáncer ha adquirido significados relacionados con la culpa, punición, deterioración, dolor y muerte, agravando el sufrimiento psicológico de las enfermas. En este sentido, este artículo tiene como objetivo levantar algunos puntos de reflexión en lo que se relaciona con los significados culturales de la enfermedad y del significado del seno como icono de la identidad femenina. Partimos del supuesto de que enriquecer la comprensión de los aspectos que pueden influenciar el sufrimiento de la mujer

    Full Text Available Introducción. USA300 es un linaje genético que se encuentra en aislamientos de Staphylococcus aureus sensibles (SASM y resistentes a meticilina (SARM. Actualmente, en Colombia las infecciones por SARM en hospitales y en la comunidad son causadas principalmente por un clon con genotipo comunitario (SARM-GC relacionado genéticamente con el clon USA300. El origen de esta variante es aún desconocido. Objetivo. Identificar y caracterizar aislamientos de S. aureus resistentes y sensibles a meticilina con el fin de aportar información para establecer un posible origen de los aislamientos SARM-GC en Colombia. Materiales y métodos. Se realizó una caracterización de aislamientos SASM relacionados con el clon USA300 detectados a partir de un análisis de 184 aislamientos de S. aureus (90 SARM y 94 SASM causantes de infecciones. La relación genética de los aislamientos se determinó por electroforesis en gel de campo pulsado (PFGE, tipificación de secuencias multilocus (MLST y tipificación del gen de la proteína A (spa. Resultados. De los 184 aislamientos, 27 (14,7 % presentaron características moleculares y relación genética con el clon USA300, y de ellos, 18 fueron SARM y nueve fueron SASM. Todos los aislamientos SARM relacionados con este clon albergaban un casete estafilocócico cromosómico mec (SCCmec IVc (3.1.2. En ningún aislamiento SASM se detectaron secuencias remanentes de SCCmec o una duplicación del sitio attB que evidenciaran la pérdida del casete. Conclusión. El origen de los aislamientos SARM-GC en Colombia probablemente se encuentre en la diseminación de clones SASM relacionados con el clon USA300 que adquirieron el SCCmec IVc posteriormente.

  15. Clustering recommendations to compute agent reputation

    Science.gov (United States)

    Bedi, Punam; Kaur, Harmeet

    2005-03-01

    Traditional centralized approaches to security are difficult to apply to multi-agent systems which are used nowadays in e-commerce applications. Developing a notion of trust that is based on the reputation of an agent can provide a softer notion of security that is sufficient for many multi-agent applications. Our paper proposes a mechanism for computing reputation of the trustee agent for use by the trustier agent. The trustier agent computes the reputation based on its own experience as well as the experience the peer agents have with the trustee agents. The trustier agents intentionally interact with the peer agents to get their experience information in the form of recommendations. We have also considered the case of unintentional encounters between the referee agents and the trustee agent, which can be directly between them or indirectly through a set of interacting agents. The clustering is done to filter off the noise in the recommendations in the form of outliers. The trustier agent clusters the recommendations received from referee agents on the basis of the distances between recommendations using the hierarchical agglomerative method. The dendogram hence obtained is cut at the required similarity level which restricts the maximum distance between any two recommendations within a cluster. The cluster with maximum number of elements denotes the views of the majority of recommenders. The center of this cluster represents the reputation of the trustee agent which can be computed using c-means algorithm.

    1996-01-01

    We investigated and compared signal intensity and the effect of imaging the upper abdomen with blueberry juice (B.J.), a Mn agent utilizing the properties of paramagnetic metals, and FerriSeltz (F.S.), an iron agent. Since the relaxation effect was much stronger with B.J. than with F.S., the signal intensity required of a peroral contrast agent was able to be obtained at a much lower concentration of B.J. In imaging the upper abdomen, B.J. had a positive effect on imaging in T1-weighted images, and a negative effect in T2-weighted images. F.S. had a positive imaging effect in both, and because it showed extremely high signals in T2-weighted images, motion artifact arose. (author)

  4. Strategic management of biotechnology agents.

    Science.gov (United States)

    Huber, S L

    1993-07-01

    The use of biologic response modifiers to demonstrate a value-driven approach to strategic management by pharmacists is described. To participate in decisions on the use of technology in their institutions, pharmacists must practice strategic management. This process includes environmental scanning, analysis of clinical and pharmacoeconomic data, and development of clinical management approaches. It is ideal for analyzing biologic response modifiers such as filgrastim and sargramostim. Emphasis must be placed on maximizing the fit among the products, the institution, and the health care environment. Pharmacists will find plentiful opportunities for clinical management with biotechnology agents. Practitioners who specialize in determining the total cost of care by using pharmacoeconomic methods are needed, as are practitioners trained to monitor the complicated biotechnology agents. Also, the institution needs to forecast accurately the impact of emerging biotechnology agents. If pharmacists can develop and control clinical, pharmacoeconomic, and reimbursement information databases for biotechnology agents, the pharmacy profession will be in a strong position to meet the challenges of biotechnology and realize the inherent opportunities.

  5. Bridging humans via agent networks

    1994-01-01

    Recent drastic advance in telecommunication networks enabled the human organization of new class, teleorganization, which differ from any existing organization in that the organization which is easy to create by using telecommunication networks is virtual and remote, that people can join multiple organizations simultaneously, and that the organization can involve people who may not know each other. In order to enjoy the recent advance in telecommunication, the agent networks to help people organize themselves are needed. In this paper, an architecture of agent networks, in which each agent learns the preference or the utility functioin of the owner, and acts on behalf of the owner in maintaining the organization, is proposed. When an agent networks supports a human organization, the conventional human interface is divided into personal and social interfaces. The functionalities of the social interface in teleconferencing and telelearning were investigated. In both cases, the existence of B-ISDN is assumed, and the extension to the business meeting scheduling using personal handy phone (PHS) networks with personal digital assistant (PDA) terminals is expected. These circumstances are described. Mutual selection protocols (MSP) and their dynamic properties are explained. (K.I.)

A pilot survey was conducted in the southwestern United States among real estate agents, realtor(s, and brokers. After testing the hypothesis, the decision was made to fail to reject the hypothesis and conclude that real estate agent experience and not Procuring Cause Law produced favorable outcomes in disputes. As a result, the following recommendations were made: (a Agency seller and buyer’s agreements should be used in each transaction to avoid disputes, (b proper expectations and guidelines should be reviewed prior to starting any real estate transaction, (c a checklist may assist in the assurance that all valuable information is reviewed, (d agents could benefit from fully understanding Procuring Cause Law and sharing this information with their clients, (e state and national regulatory requirements of the law could be modified for easier understanding and use, and (f consumers who willfully violate the law could be subject to monetary penalties.

    1995-02-01

    The intended phaseout of the chlorofluorocarbons (CFCs) from commercial use required the evaluation of substitute materials for the testing for leak paths through both individual adsorbers and installed adsorbent banks. The American Society of Mechanical Engineers (ASME) Committee on Nuclear Air and Gas Treatment (CONAGT) is in charge of maintaining the standards and codes specifying adsorbent leak test methods for the nuclear safety related air cleaning systems. The currently published standards and codes cite the use of R-11, R-12 and R-112 for leak path test agents. All of these compounds are CFCs. There are other agencies and organizations (USDOE, USDOD and USNRC) also specifying testing for leak paths or in some cases for special life tests using the above compounds. The CONAGT has recently developed criteria for the suitability evaluation of substitute test agents. On the basis of these criteria, several compounds were evaluated for their acceptability as adsorbent bed leak and life test agents. The ASME CONAGT Test Agent Qualification Criteria. The test agent qualification is based on the following parameters: (1) Similar retention times on activated carbons at the same concentration levels as one of the following: R-11, R-12, R-112 or R-112a. (2) Similar lower detection limit sensitivity and precision in the concentration range of use as R-11, R-12, R-112 and R-112a. (3) Gives the same in-place leak test results as R-11, R-12, R-112, or R-112a. (4) Chemical and radiological stability under the use conditions. (5) Causes no degradation of the carbon and its impregnant or of the other NATS components under the use conditions. (6) Is listed in the USEPA Toxic Substances Control Act (TSCA) inventory for commercial use.

    Full Text Available OBJETIVO: Determinar a prevalência de eczema atópico e de sintomas relacionados entre estudantes da região centro-sul da cidade de São Paulo, em 1996 e 1999. MÉTODOS: Em 1996 e 1999, o questionário escrito do International Study of Asthma and Allergies in Childhood (ISAAC foi aplicado aos pais de crianças com 6-7 anos (3.005 em 1996 e 3.033 em 1999 e a adolescentes de 13-14 anos (3.008 em 1996 e 3.487 em 1999. Para o ISAAC: a o relato de eczema alguma vez indica que, pelo menos uma vez na vida, foi fornecido por um médico o diagnóstico de eczema atópico, sendo utilizado para definir "diagnóstico médico" b o relato concomitante de lesões no último ano evidenciadas em locais característicos constitui o "critério combinado" para o diagnóstico de eczema atópico e foi, também, utilizado por nós. Os dados obtidos foram transcritos no banco de dados Epi-Info 6.0 e analisados. RESULTADOS: No grupo dos 6-7 anos houve redução significante do "diagnóstico médico" de eczema atópico em 1999 (11,4% em comparação a 1996 (13,2%. O aumento da prevalência de "diagnóstico médico" observado em 1999, entre os adolescentes, não foi significante (14% x 15%.

    There are many facets to cancer prevention: a good diet, weight control and physical activity, a healthy environment, avoidance of carcinogens such as those in tobacco smoke, and screening of populations at risk to allow early detection. But there is also the possibility of using drugs or naturally occurring compounds to prevent initiation of, or to suppress, tumour growth. Only a few such agents have been used to date in the clinic with any success, and these include non-steroidal anti-inflammatory drugs for colon, finasteride for prostate and tamoxifen or raloxifene for breast tumours. An ideal chemopreventive agent would restore normal growth control to a preneoplastic or cancerous cell population by modifying aberrant signalling pathways or inducing apoptosis (or both) in cells beyond repair. Characteristics for such an agent include selectivity for damaged or transformed cells, good bioavailability and more than one mechanism of action to foil redundancy or crosstalk in signalling pathways. As more research effort is being targeted towards this area, the distinction between chemotherapeutic and chemopreventive agents is blurring. Chemotherapeutic drugs are now being designed to target over- or under-active signalling molecules within cancer cells, a philosophy which is just as relevant in chemoprevention. Development of dietary agents is particularly attractive because of our long-standing exposure to them, their relative lack of toxicity, and encouraging indications from epidemiology. The carcinogenic process relies on the cell's ability to proliferate abnormally, evade apoptosis, induce angiogenesis and metastasise to distant sites. In vitro studies with a number of different diet-derived compounds suggest that there are molecules capable of modulating each of these aspects of tumour growth. However, on the negative side many of them have rather poor bioavailability. The challenge is to uncover their multiple mechanisms of action in order to predict their

    This report describes preliminary research on intelligent agents that make errors. Such agents are crucial to the development of novel agent-based techniques for assessing system safety. The agents extend an agent architecture derived from the Crew Activity Tracking System that has been used as the basis for air traffic controller agents. The report first reviews several error taxonomies. Next, it presents an overview of the air traffic controller agents, then details several mechanisms for causing the agents to err in realistic ways. The report presents a performance assessment of the error-generating agents, and identifies directions for further research. The research was supported by the System-Wide Accident Prevention element of the FAA/NASA Aviation Safety Program.

    Progress made in applying agent systems to molecular computational biology is reviewed and strategies by which to exploit agent technology to greater advantage are investigated. Communities of software agents could play an important role in helping genome scientists design reagents for future research. The advent of genome sequencing in cattle and swine increases the complexity of data analysis required to conduct research in livestock genomics. Databases are always expanding and semantic differences among data are common. Agent platforms have been developed to deal with generic issues such as agent communication, life cycle management and advertisement of services (white and yellow pages). This frees computational biologists from the drudgery of having to re-invent the wheel on these common chores, giving them more time to focus on biology and bioinformatics. Agent platforms that comply with the Foundation for Intelligent Physical Agents (FIPA) standards are able to interoperate. In other words, agents developed on different platforms can communicate and cooperate with one another if domain-specific higher-level communication protocol details are agreed upon between different agent developers. Many software agent platforms are peer-to-peer, which means that even if some of the agents and data repositories are temporarily unavailable, a subset of the goals of the system can still be met. Past use of software agents in bioinformatics indicates that an agent approach should prove fruitful. Examination of current problems in bioinformatics indicates that existing agent platforms should be adaptable to novel situations.

    Artificial intelligence systems (agents) generally have models of the environments they inhabit which they use for representing facts, for reasoning about these facts and for planning actions. Much intelligent behaviour seems to involve an ability to model not only one's external environment...... introspective reasoning, the presence of self-reference causes the theory to be prone to inconsistency. The challenge therefore becomes to construct logical theories supporting introspective reasoning while at the same time ensuring that consistency is retained. In the thesis, we meet this challenge by devising...... by developments within semantics for logic programming within computational logic and formal theories of truth within philosophical logic. The thesis provides a number of examples showing how the developed theories can be used as reasoning frameworks for agents with introspective abilities. In Danish...

    Purpose: To apply solidifying treatment to boron-containing radioactive wastes while improving the durability, rapid hardening property and processing performance, as well as reducing the leaching property. Constitution: A solidifying agent comprising calcium aluminate having CaO and Al 2 O 3 at 1.5 - 4 molar ratio, super fine powder and high performance moderator is used. As the super fine powder, those having a grain size smaller by 1 - 2 orders than that of the calcium aluminate are preferred. Specifically, there can be used silica dust, calcium carbonate, silica gel, titanium oxide, aluminum oxide, etc. As the moderator, there are used those surface active agents of great dispersing performance not causing excess delay for coagulation or excess air entrainment when added in a great amount to cements. Specifically, there can be mentioned those mainly composed of salts of naphthalene sulfonic acid-formaldehyde condensates, salts of melamine sulfonic acid formaldehyde condensates, etc. (Ikeda, J.)

    This paper presents the development of a motivated learning (ML) agent with symbolic I/O. Our earlier work on the ML agent was enhanced, giving it autonomy for interaction with other agents. Specifically, we equipped the agent with drives and pains that establish its motivations to learn how to respond to desired and undesired events and create related abstract goals. The purpose of this paper is to explore the autonomous development of motivations and memory in agents within a simulated environment. The ML agent has been implemented in a virtual environment created within the NeoAxis game engine. Additionally, to illustrate the benefits of an ML-based agent, we compared the performance of our algorithm against various reinforcement learning (RL) algorithms in a dynamic test scenario, and demonstrated that our ML agent learns better than any of the tested RL agents.This paper presents the development of a motivated learning (ML) agent with symbolic I/O.

    Full Text Available Purpose – Preponderant agent is a new instrument for preventing and reverting adverse impact in competition due to highly concentrated markets. Therefore, this paper's objective is to present and analyze the preponderant agent concept in Mexico with emphasis on the broadcast sector, the telecommunication regulator decisions and the courts' interpretation. Methodology/approach/design – The objectives were achieved by researching and analyzing the main legal documents, the Congress reports and debates, the regulator's decisions and other relevant regulator's documents, as well as final decisions by the courts in connection with broadcast sector. Findings – Among the findings are that certain topics were not duly addressed by the Mexican regulator, or by the Congress, whereas the courts were more willing to hold decisions in favor of public interest based on constitutional intent and deference to the regulator's decision. Originality/value – This paper will be valuable for persons interested in telecommunications, broadcast and antitrust. Although the preponderant agent concept created in Mexico is not necessarily a “best practice”, it does provide an alternative instrument in antitrust. Moreover, the courts decisions also provide criteria regarding regulatory deference for the regulator.

  15. Solidification agent for radioactive waste

    Sakai, Etsuro; Shibayama, Yukio.

    1986-01-01

    Purpose: In low and medium level radioactive waste processing, to obtain superior solidified blocks by mixing cement, super-fine dusts and high-performance water-reducing agent and water to radioactive waste materials for solidification. Constitution: The various types of portland cements available are used for solidification. Silica dust is used as the super-fine dust and has an average article size of one order smaller than that of the cement used for solidification. Napthalene, sulfonic acid formalydehyde condensation salts etc. are used as the water-reducing agents. For example, for hundred units, by weight, of cement and super-fine dust 10 units (by solid content) are added. Furthermore, smaller quantities of water are desirable. By mixing the radioactive wastes with cement, super-fine dust, water-reducing agents, and water, the solidified material shows superior chemical resistance and durability. The processing capacity is also increased. Furthermore, a more leach resistant solid can be obtained for storage. (Takahashi, M.)

    Undertreatment of hyperlipidemia has received considerable attention. However, little is known about trends in overprescribing of lipid lowering agents. We examined these trends and their associations with physician, practice, and organisational factors. 2034 physicians were surveyed twice: baseline (1996-7) and follow up (1998-9). On each occasion they were asked: "For what percentage of 50 year old men without other cardiac risk factors would you recommend an oral agent for total cholesterol of 240, LDL 150, and HDL 50 after 6 months on a low cholesterol diet?" During the survey period the National Cholesterol Education Program guidelines did not recommend prescribing for these patients. Binomial and multinomial logistic regressions assessed baseline overprescribing and longitudinal changes in overprescribing, accounting for complex sampling. 39% of physicians recommended prescribing at baseline (round 1), increasing at follow up (round 2) to 51% (p overprescribe at baseline were less likely to be board certified (odds ratio (OR) 0.49, 95% confidence interval (CI) 0.38 to 0.63; p overprescribing to be international medical graduates (OR 2.09, 95% CI 1.20 to 3.64; p = 0.011) and to spend more hours in patient care (OR 1.14, 95% CI 1.03 to 1.26; p = 0.016). Overprescribing of lipid lowering agents is commonplace and increased. At baseline and longitudinally, overprescribing was primarily associated with physician and practice characteristics and not with organisational factors.

  17. Commission of the commercial agent

    Directory of Open Access Journals (Sweden)

    Radović Mirjana

    2015-01-01

    Full Text Available In this paper the author analyses the commercial agent's commission as the most important type of remuneration for commercial agency. In the European Union the issue of commercial agent's commission is regulated in the Directive 86/653/EEC on self-employed commercial agents, whereas the Serbian Law on Obligations has still not been harmonised with those rules. Such state of law would change if and when the new Serbian Civil Code is enacted, since its latest Draft contains numerous new solutions, which were inspired by the Directive. The first part of the paper is dedicated to defining the term 'commission' and its distinguishing from the wider term 'remuneration'. Thereafter, the main types of commission are explained. The following part investigates whether the commission or its specific type constitutes essentialia or naturalia negotii of the contract on commercial agency. Finally, the last part of the paper deals with the amount and the extent of covering costs by the commission, in the absence of any agreement on that matter.

    Full Text Available An agent is a self-contained process being acting on behalf of a user. A Mobile Agent is an agent roaming the internet to access data and services, and carry out its assigned task remotely. This paper will focus on the communication models for Mobile Agents. Generally speaking, communication models concern with problems of how to name Mobile Agents, how to establish communication relationships, how to trace moving agents, and how to guarantee reliable communication. Some existing MA systems are purely based on RPC-style communication, whereas some adopts asynchronous message passing, or event registration/handling. Different communication concepts suitable for Mobile Agents are well discussed in [1]. However, we will investigate these concepts and existing models from a different point view: how to track down agents and deliver messages in a dynamic, changing world.

Métodos: Las defunciones por edad, sexo y causa desde 1980 a 1998 se obtuvieron del Instituto Nacional de Estadística (Movimiento Natural de la Población. Se calculó la proporción de muertes relacionadas con el alcohol para cada año, sexo y grupo de edad a partir de la fracción atribuible poblacional propuesta por los Centers for Disease Control (Estados Unidos. Para cada categoría diagnóstica, los años de vida perdidos prematuramente relacionados con el alcohol fueron calculados multiplicando las defunciones por la fracción poblacional en grupos quinquenales de edad para ambos sexos hasta la edad de 65 años. Resultados: Durante el período 1980-1998, el número de fallecimientos por causas relacionadas con el alcohol fue de 12.614, con un promedio del 6,4% anual y una razón varón/mujer de aproximadamente 2:1. Las neoplasias malignas, las enfermedades digestivas y los accidentes no intencionales relacionados con el alcohol presentan las mayores tasas de mortalidad y de AVPP tanto en varones como en mujeres; en particular, los accidentes no intencionales generan AVPP por encima de las otras causas, lo que supone el 50,6% del total de AVPP por causas relacionadas con el alcohol en varones y el 55,5% en mujeres.

    Directory of Open Access Journals (Sweden)

    2002-07-01

    Full Text Available Durante la última década ha aumentado la preocupación por el consumo de alcohol como problema de salud pública. El consumo de alcohol es especialmente problemático en América Latina y el Caribe (ALC. Mientras que en todo el mundo la proporción de muertes atribuibles al alcohol es del 1,5%, en los países de ALC esta cifra es del 4,5%. Los esfuerzos para reducir los efectos negativos del alcohol sobre la sociedad y la salud pública necesitan tener en cuenta el contexto sociocultural en el que tiene lugar el consumo, y en particular los roles de género. Este tema ha sido tratado en un documento de trabajo publicado recientemente por el Banco Mundial, cuyo contenido se resume aquí. Dicho documento afirma que el consumo y el abuso de alcohol están relacionados con los roles de los hombres y las mujeres y sus expectativas en la sociedad. Los hombres tienen mayores probabilidades que la mujeres de beber mucho, y también menos probabilidades de abstenerse de consumir alcohol. Además, hay diferentes expectativas y significados del consumo de alcohol de unos y otras y de la forma como responden a él. Las políticas sobre el alcohol adoptadas por los gobiernos deberían basarse en la eficacia y en los costos de su puesta en práctica. Estas políticas pueden clasificarse en función de cuatro grandes objetivos: 1 prevenir el consumo y los comportamientos de alto riesgo relacionados con él; 2 reducir los daños a los consumidores individuales y a sus familias y comunidades; 3 regular la disponibilidad del alcohol y las condiciones de su consumo, y 4 proporcionarles tratamiento a personas con problemas relacionados con el alcohol. Las actuales medidas legislativas de los países de ALC tratan sobre todo de reducir la disponibilidad de bebidas alcohólicas, generalmente estableciendo una edad mínima para su consumo. Sin embargo, raramente se vela por el cumplimiento de estas leyes. El documento del Banco Mundial concluye con una serie de

    Erejuwa, Omotayo O.; Sulaiman, Siti A.; Wahab, Mohd S. Ab

    2012-01-01

    Diabetes mellitus remains a burden worldwide in spite of the availability of numerous antidiabetic drugs. Honey is a natural substance produced by bees from nectar. Several evidence-based health benefits have been ascribed to honey in the recent years. In this review article, we highlight findings which demonstrate the beneficial or potential effects of honey in the gastrointestinal tract (GIT), on the gut microbiota, in the liver, in the pancreas and how these effects could improve glycemic control and metabolic derangements. In healthy subjects or patients with impaired glucose tolerance or diabetes mellitus, various studies revealed that honey reduced blood glucose or was more tolerable than most common sugars or sweeteners. Pre-clinical studies provided more convincing evidence in support of honey as a potential antidiabetic agent than clinical studies did. The not-too-impressive clinical data could mainly be attributed to poor study designs or due to the fact that the clinical studies were preliminary. Based on the key constituents of honey, the possible mechanisms of action of antidiabetic effect of honey are proposed. The paper also highlights the potential impacts and future perspectives on the use of honey as an antidiabetic agent. It makes recommendations for further clinical studies on the potential antidiabetic effect of honey. This review provides insight on the potential use of honey, especially as a complementary agent, in the management of diabetes mellitus. Hence, it is very important to have well-designed, randomized controlled clinical trials that investigate the reproducibility (or otherwise) of these experimental data in diabetic human subjects.

    Energy Technology Data Exchange (ETDEWEB)

    Wolter, Martin

    2012-07-01

    In liberalized, regulated energy markets, the different participants - namely producers and consumers of energy, transmission and distribution system operators as well as regulatory authorities - have partly divergent and partly convergent interests. Loads, power plants and grid operators try to maximize their own benefit in this highly complex environment accepting to act detrimentally to others. Although the relationship between the participants is mostly competitive, there are some fundamental shared interests, e.g. voltage stability, a constant system frequency or efficient energy production, transmission and distribution, which are endangered e.g. by increased injection of volatile sources in low and medium voltage grids, displacement of stabilizing bulk generation and the slowly progressing extension of the electric grid. There is a global consensus, that the resulting challenges can efficiently be faced using information and communication technologies to coordinate grid utilization and operation. The basic idea is to benefit from unused reserves by participating in deployment of system services e.g. reactive power supply to keep the voltage within certain bounds. The coordination can best be done by the grid operator. All activities of that kind are summarized under the umbrella term ''Smart Grid''. To simultaneously model the behavior and interests of different types of market participants and their convergent and divergent interests, multi-agent systems are used. They offer a perfectly fitting framework for this sort of game theory and can easily be adapted to all kinds of new challenges of electricity markets. In this work, multi-agent systems are used to either cooperatively or competitively solve problems in distribution and transmission systems. Therefore, conventional algorithms have to be modified to converge into multiple local optima using only small pieces of the entire system information. It is clearly stated, that personal

    Marine sponges are currently one of the richest sources of anticancer active compounds found in the marine ecosystems. More than 5300 different known metabolites are from sponges and their associated microorganisms. To survive in the complicated marine environment, most of the sponge species have evolved chemical means to defend against predation. Such chemical adaptation produces many biologically active secondary metabolites including anticancer agents. This review highlights novel secondary metabolites in sponges which inhibited diverse cancer species in the recent 5 years. These natural products of marine sponges are categorized based on various chemical characteristics.

    1990-01-01

    Based upon fluorescence measurements, protein binding of some psychotropic agents (chlorpromazine, promethazine, and trifluoperazine) to human IgG and HSA was studied in aqueous cacodylate buffer, PH7. The interaction parameters determined from emission quenching of the proteins. The interaction parameters determined include the equilibrium constant (K), calculated from equations derived by Borazan and coworkers, the number of binding sites (n) available to the monomer molecules on a single protein molecule. The results revealed a high level of affinity, as reflected by high values of K, and the existence of specific binding sites, since a limited number of n values are obtained. 39 tabs.; 37 figs.; 83 refs

    Fabian, Elisabeth; Kump, Patrizia; Krejs, Guenter J

    2012-09-01

    Circulating agents cause intestinal secretion or changes in motility with decreased intestinal transit time, resulting in secretory-type diarrhea. Secretory diarrhea as opposed to osmotic diarrhea is characterized by large-volume, watery stools, often more than 1 L per day; by persistence of diarrhea when patients fast; and by the fact that on analysis of stool-water, measured osmolarity is identical to that calculated from the electrolytes present. Although sodium plays the main role in water and electrolyte absorption, chloride is the major ion involved in secretion. Copyright © 2012 Elsevier Inc. All rights reserved.

  13. Effectiveness testing of spill-treating agents

    International Nuclear Information System (INIS)

    Fingas, M.F.; Stoodley, R.; Laroche, N.

    1990-01-01

    Laboratory effectiveness tests are described for four classes of spill-treating agents: solidifiers, demulsifying agents, surface-washing agents and dispersants. Many treating agents in these four categories have been tested for effectiveness and the results are presented. Solidifiers or gelling agents solidify oil, requiring a large amount of agent to solidify oil-ranging between 16% by weight, to over 200%. Emulsion breakers prevent or reverse the formation of water-in-oil emulsions. A newly-developed effectiveness test shows that only one product is highly effective; however, many products will work, but require large amounts of spill-treating agent. Surfactant--containing materials are of two types, surface-washing agents and dispersants. Testing has shown that an agent that is a good dispersant is conversely a poor surface-washing agent, and vice versa. Tests of surface-washing agents show that only a few agents have effectiveness of 25-40%, where this effectiveness is the percentage of heavy oil removed from a test surface. Results using the 'swirling flask' test for dispersant effectiveness are reported. Heavy oils show effectiveness values of about 1%, medium crudes of about 10%, light crude oils of about 30% and very light oils of about 90%. (author)

    Full Text Available Objective: To assess the frequency and types of drug-related problems (DRPs in patients seeking emergency care in a teaching hospital in southern Brazil and to identify the possible causes and drugs involved in these problems. Method: A cross-sectional study was performed, using a structured questionnaire for data collection. Multivariate logistic regression was used to control for possible confounding factors and to establish an independent association between the presence of DRPs and the amount of medication, patient's age and their educational level. Results: A total of 350 patients were interviewed. The frequency of DRPs was 31.6%. Quantitative ineffectiveness was observed in 30.9% of DRPs and the main cause of the DRP was an inadequate dosing regimen. Sixty-six DRPs (53.7% were caused by the health system or the health professionals. Factors independently influencing the development of DRPs were educational level and the number of drugs being taken. Conclusions: Our data suggest that one-third of the patients attending the emergency room of our hospital had a drug-related problem, highlighting the importance of considering drugs as a possible cause of health problems and the need for their more rational use.Objetivo: Evaluar la frecuencia y el tipo de problemas relacionados con medicamentos que presentan los pacientes que acuden al servicio de urgencias en un hospital universitario del sur de Brasil, e identificar las posibles causas y los fármacos involucrados.

    An agent is a small program acting on behalf of a user or an application which plays the role of a user. Artificial intelligence can be encapsulated in agents so that they can be capable of both behaving autonomously and showing an elementary decision ability regarding movement and some specific actions. Therefore they are often called autonomous mobile agents. In a distributed system, they can move themselves from one processing node to another through the interconnecting network infrastructure. Their purpose is to collect useful information and to carry it back to their user. Also, agents are used to start, monitor and stop processes running on the individual interconnected processing nodes of computer cluster systems. An agent has a unique id to discriminate itself from other agents and a current position. The position can be expressed as the address of the processing node which currently hosts the agent. Very often, it is necessary for a user, a processing node or another agent to know the current position of an agent in a distributed system. Several procedures and algorithms have been proposed for the purpose of position location of mobile agents. The most basic of all employs a fixed computing node, which acts as agent position repository, receiving messages from all the moving agents and keeping records of their current positions. The fixed node, responds to position queries and informs users, other nodes and other agents about the position of an agent. Herein, a model is proposed that considers pairs and triples of agents instead of single ones. A location method, which is investigated in this paper, attempts to exploit this model.

  1. Nonsteroid anti-inflammatory agents.

    Science.gov (United States)

    Paulus, H E; Whitehouse, M W

    1973-01-01

    Nonsteroidal antiinflammatory agents (NSAID) are reviewed. Aspirin, indomethacin, and salicylate have all been shown to interfere or prevent the synthesis of prostaglandins (PGs), a main tissue inflammatory substance. However, an exception to the correlation of PG-synthetase inhibition with antiinflammatory activity has been noted with certain arylacetic acids. Studies on the role of lysosomes in the inflammation are criticized in this review, mainly because of improper understanding of the role of lysosomes in a physiological system. Since lysosomes are not a specific body, but an activator, attempts to isolate lysosomes to study functions are doomed to failure; i.e., a lysosome has no definition without the rest of its self-regulating system. NSAIDs work in 2 main ways; either via antiaggregation or antiinflammation. This may result in drug interactions between various types of NSAIDs. For example, simultaneous administration of aspirin with indomethacine did not produce an additive effect; rather they produced no effect in the rat paw edema test dissimilar to the action of either drug separately. However, hydrocortisone combined with another NSAID enhanced its antiinflammatory effects. Albumin binding theories of NSAID mechanism of action state that drugs are active only when albumin-bound because it has displaced tryptophane, or urate, or some other normally bound substance. The only way to discover an efficient antiinflammatory agent is to obviate the need for it by discovering the actual mechanism of inflammation, for when specific anti-etiologic therapy is developed, the need for treatment with NSAIDs is irrelevant.

    Hospitals are breeding grounds for many life-threatening bacteria worldwide. Clinically associated gram-positive bacteria such as Staphylococcus aureus/methicillin-resistant S. aureus and many others increase the risk of severe mortality and morbidity. The failure of antibiotics to kill various pathogens due to bacterial resistance highlights the urgent need to develop novel, potent, and less toxic agents from natural sources against various infectious agents. Currently, several promising classes of natural molecules from snake (terrestrial and sea), scorpion, spider, honey bee and wasp venoms hold promise as rich sources of chemotherapeutics against infectious pathogens. Interestingly, snake venom-derived synthetic peptide/snake cathelicidin not only has potent antimicrobial and wound-repair activity but is highly stable and safe. Such molecules are promising candidates for novel venom-based drugs against S. aureus infections. The structure of animal venom proteins/peptides (cysteine rich) consists of hydrophobic α-helices or β-sheets that produce lethal pores and membrane-damaging effects on bacteria. All these antimicrobial peptides are under early experimental or pre-clinical stages of development. It is therefore important to employ novel tools for the design and the development of new antibiotics from the untapped animal venoms of snake, scorpion, and spider for treating resistant pathogens. To date, snail venom toxins have shown little antibiotic potency against human pathogens. Copyright © 2017 Elsevier Inc. All rights reserved.

    Li, Fangfei; Collins, J Grant; Keene, F Richard

    2015-04-21

    One of the major advances in medical science has been the development of antimicrobials; however, a consequence of their widespread use has been the emergence of drug-resistant populations of microorganisms. There is clearly a need for the development of new antimicrobials--but more importantly, there is the need for the development of new classes of antimicrobials, rather than drugs based upon analogues of known scaffolds. Due to the success of the platinum anticancer agents, there has been considerable interest in the development of therapeutic agents based upon other transition metals--and in particular ruthenium(II/III) complexes, due to their well known interaction with DNA. There have been many studies of the anticancer properties and cellular localisation of a range of ruthenium complexes in eukaryotic cells over the last decade. However, only very recently has there been significant interest in their antimicrobial properties. This review highlights the types of ruthenium complexes that have exhibited significant antimicrobial activity and discusses the relationship between chemical structure and biological processing--including site(s) of intracellular accumulation--of the ruthenium complexes in both bacterial and eukaryotic cells.

    Applications of wetting-agent solutions produce mortality in birds. The exact cause of death is undetermined but it is believed that destruction of the insulating qualities of the plumage permits ambient cold temperatures and evaporation to lower the body temperature to a lethal level. The original concept of using these materials as bird-control tools was developed in 1958 at the Patuxent Wildlife Research Center, Bureau of Sport Fisheries and Wildlife Laurel, Maryland. Early field trials by personnel of the Division of Wildlife Services and the Denver Wildlife Research Center indicated that ground-application techniques had promise but limitations of the equipment precluded successful large-scale roost treatments. In 1966, Patuxent Center personnel began using tanker-type aircraft to evaluate high-volume aerial applications of wetting agents. The success of these tests led to the use of small aircraft to make low-volume, high-concentration aerial applications just prior to expected rainfall. Recent trials of the low-volume method show that, with some limitations, it is effective, inexpensive, and safe to the environment. Current research emphasizes the screening of new candidate materials for efficacy, biodegradability, and toxicity to plants and non-target animals, as well as basic investigations of the avian physiological mechanisms involved. Field trials to develop more effective application techniques will continue.

Dentre essas, percebemos que o foco sobre textos escritos está geralmente relacionado ao seu funcionamento em situações didáticas na sala de aula de ciências. Buscando contribuir para a ampliação do escopo de pesquisas filiadas aos estudos do discurso, é apresentado um exercício de análise de textos de um livro didático de ciências e de uma revista de divulgação científica utilizando a Análise de Discurso como base teórica para a elaboração de um dispositivo analítico que se divide em três etapas: seleção do corpus, descrição do corpus e interpretação do objeto discursivo buscando caracterizar dois gêneros textuais específicos relacionados a diferentes formações discursivas. Os resultados mostram que os textos do livro didático e de divulgação científica são atravessados por diferentes formações discursivas que se remetem aos discursos da ciência, do cotidiano e do ensino de ciências.

    Full Text Available Despite the advent of short and ultra-short acting drugs, an in-depth knowledge of the reversal agents used is a necessity for any anaesthesiologist. Reversal agents are defined as any drug used to reverse the effects of anaesthetics, narcotics or potentially toxic agents. The controversy on the routine reversal of neuromuscular blockade still exists. The advent of newer reversal agents like sugammadex have made the use of steroidal neuromuscular blockers like rocuronium feasible in rapid sequence induction situations. We made a review of the older reversal agents and those still under investigation for drugs that are regularly used in our anaesthesia practice.

  11. Variations on agent-oriented programming

    Full Text Available Occurrence of the agent paradigm and its further applications have stimulated the emergence of new concepts and methodologies in computer science. Today terms like multi-agent system, agent-oriented methodology, and agent-oriented programming (AOP are widely used. The aim of this paper is to clarify the validity of usage of the terms AOP and AOP language. This is disclosed in two phases of an analysis process. Determining to which concepts, terms like agent, programming, object-oriented analysis and design, object-oriented programming, and agent-oriented analysis and design correspond is accomplished in the first phase. Analysis of several known agent system engineering methodologies in terms of key concepts used, final resulting artifacts, and their relationship with known programming paradigms and modern tools for agent system development is performed in the second phase. The research shows that in most cases in the final phase of agent system design and in the coding stage, the main artifact is an object, defined according to the rules of the object-oriented paradigm. Hence, we say that the computing society still does not have AOP owing to the lack of an AOP language. Thus, the term AOP is very often incorrectly assigned to agent system development frameworks that in most cases, transform agents into objects.DOI: 10.15181/csat.v5i1.1361

  12. Introduction to Agent Mining Interaction and Integration

    Science.gov (United States)

    Cao, Longbing

    In recent years, more and more researchers have been involved in research on both agent technology and data mining. A clear disciplinary effort has been activated toward removing the boundary between them, that is the interaction and integration between agent technology and data mining. We refer this to agent mining as a new area. The marriage of agents and data mining is driven by challenges faced by both communities, and the need of developing more advanced intelligence, information processing and systems. This chapter presents an overall picture of agent mining from the perspective of positioning it as an emerging area. We summarize the main driving forces, complementary essence, disciplinary framework, applications, case studies, and trends and directions, as well as brief observation on agent-driven data mining, data mining-driven agents, and mutual issues in agent mining. Arguably, we draw the following conclusions: (1) agent mining emerges as a new area in the scientific family, (2) both agent technology and data mining can greatly benefit from agent mining, (3) it is very promising to result in additional advancement in intelligent information processing and systems. However, as a new open area, there are many issues waiting for research and development from theoretical, technological and practical perspectives.

    Full Text Available In the past decade agent systems were considered to be as one of the major fields of study in Artificial Intelligence (AI field. Many different definitions of agents were presented and several different approaches describing agency can be distinguished. While some authors have tried to define “what” an agent really is, others have tried to identify agents by means of properties which they should possess. Most authors agree on these properties (at least basic set of properties which are intrinsic to agents. Since agent's definitions are not consistent, we are going to give an overview and list the properties intrinsic to an agent. Many different adjectives were attached to the term agent as well and many different kinds of agents and different architectures emerged too. The aim of this paper it go give an overview of what was going on in the field while taking into consideration main streams and projects. We will also present some guidelines important when modelling agent systems and say something about security issues. Also, some existing problems which restrict the wider usage of agents will be mentioned too.

    Open systems are characterized by the presence of a diversity of heterogeneous and autonomous agents that act according to private goals. Organizations, such as those used in real-life to structure human activities such as task allocation, coordination and supervision, can regulate the agents...... boundaries and work towards the objectives of the organization. In this paper, we present the AORTA reasoning framework and show how it can be integrated into typical BDI-agents. We provide operational semantics that enables agents to make organizational decisions in order to coordinate and cooperate without...... explicit coordination mechanisms within the agents. The organizational model is independent of that of the agents, and the approach is not tied to a specific organizational model, but uses an organizational metamodel. We show how AORTA helps agents work together in a system with an organization...

    2016-08-01

    The paper is meant to be a dynamic approach to optimize manufacturing systems based on multi-agent systems. Multi-agent systems are semiautonomous decision makers and cooperate to optimize the manufacturing process. Increasing production the capacity is achieved by developing, implementing efficient and effective systems from control based on current manufacturing process. The model multi-agent proposed in this paper is based on communication between agents who, based on their mechanisms drive to autonomous decision making. Methods based on multi-agent programming are applied between flexible manufacturing processes and cooperation with agents. Based on multi-agent technology and architecture of intelligent manufacturing can lead to development of strategies for control and optimization of scheduled production resulting from the simulation.

    Development of agent systems has been surveyed, to classify and arrange characteristic functions of the agents, and to grasp the realization situation of these agents in their development. In addition, prospective functions of information retrieval systems using the agents at maximum and functions to be developed among these in the future are clarified. The agents are characterized by the expression function, communication function, planning function, adaptive function, and learning function. The agents are desired to be classified into interface agents whose works are to respond to individual workers, coordinator agents which conduct works with high pervasion, such as assignment of works and their control, and task agents which conduct specialized works for individual examples. Thus, design and configuration of the agent system, and improvement and expansion of system functions can be effectively and easily conducted. 52 refs., 5 figs., 3 tabs.

    Full Text Available Food poisoning is the one of the main health hazards even today. More than 200 known diseases are transmitted through food. The causes of foodborne illness include viruses, bacteria, parasites, toxins, metals, and prions and the symptoms of foodborne illness range from mild gastroenteritis to life-threatening neurological, hepatic and renal syndromes.The prevention of food poisonings represents very serious task for food manufacturers. Beside food control according to the concept "from the farm to the table" there is increased need for the development of new technology for longer shelf lifes of food. Food fermented by lactic acid bacteria (LAB and traditionally considered to be safe. There are many substances produced by LAB that affect the shelf life of fermented food, by active suppression of poisoning microorganisms growth. Because of that, the LAB is recently considered as bioprotective agents that have important role in food safety.

    Denny, W A

    2001-04-01

    Recent work on a number of different classes of anticancer agents that alkylate DNA in the minor groove is reviewed. There has been much work with nitrogen mustards, where attachment of the mustard unit to carrier molecules can change the normal patterns of both regio- and sequence-selectivity, from reaction primarily at most guanine N7 sites in the major groove to a few adenine N3 sites at the 3'-end of poly(A/T) sequences in the minor groove. Carrier molecules discussed for mustards are intercalators, polypyrroles, polyimidazoles, bis(benzimidazoles), polybenzamides and anilinoquinolinium salts. In contrast, similar targeting of pyrrolizidine alkylators by a variety of carriers has little effect of their patterns of alkylation (at the 2-amino group of guanine). Recent work on the pyrrolobenzodiazepine and cyclopropaindolone classes of natural product minor groove binders is also reviewed.

  4. Blasting agents and initiation systems

    2000-01-01

    Although blasting differs between and within each industry, as a whole, the mines and quarries are making a shift from a purely ammonium nitrate/fuel oil (ANFO) mixture to a blend of emulsion and ANFO on a straight emulsion. Non-electric (shock tube) initiation systems have provided a viable alternative to the electric detonator (blasting cap). Explosives manufacturers are seeing their roles changes to being blasting contractors or consultants rather than just suppliers. The article discusses these trends and gives examples of typical blasting techniques and amounts of blasting agent used at large USA surface coal mines. Electric caps are still used in blasting underground coal. The Ensign Bickford Co. (EBCo) is developing electronic detonators and has been field testing an electronic initiator, the DIGIDET detonator, for the last four years. When commercially available, electronic detonators will be accurate but will come with a hefty price tag. 2 photos.

    Pierre Tchounikine

    2004-04-01

    Full Text Available This paper describes a multi- agent approach that aims at supporting learners involved in a collective activity. We consider pedagogical situations where students have to explicitly define the articulation of their collective work and then achieve the different tasks they have defined. Our objective is to support these students by taking some of these tasks in charge whilst making them work out such organisation features. For this purpose, we propose to consider that the group of students forms a multi- agent system and to introduce software agents that can achieve some of the tasks within this group. This conducts students to tackle the problem in terms of human and software agent coordination. We present how this approach can be conceptualized and modelled using Engeström’s triangle, how task delegation can be used as a means to enable students to define the software agents’ behaviour and the multi-agent implementation we propose.

  9. Persuasive Conversational Agent with Persuasion Tactics

    Science.gov (United States)

    Narita, Tatsuya; Kitamura, Yasuhiko

    Persuasive conversational agents persuade people to change their attitudes or behaviors through conversation, and are expected to be applied as virtual sales clerks in e-shopping sites. As an approach to create such an agent, we have developed a learning agent with the Wizard of Oz method in which a person called Wizard talks to the user pretending to be the agent. The agent observes the conversations between the Wizard and the user, and learns how to persuade people. In this method, the Wizard has to reply to most of the user's inputs at the beginning, but the burden gradually falls because the agent learns how to reply as the conversation model grows.

  10. Radioiodine: the classic theranostic agent.

    2012-05-01

    Radioiodine has the distinction of being the first theranostic agent in our armamentarium. Millennia were required to discover that the agent in orally administered seaweed and its extracts, which had been shown to cure neck swelling due to thyromegaly, was iodine, first demonstrated to be a new element in 1813. Treatment of goiter with iodine began at once, but its prophylactic value to prevent a common form of goiter took another century. After Enrico Fermi produced the first radioiodine, (128)I, in 1934, active experimentation in the United States and France delineated the crucial role of iodine in thyroid metabolism and disease. (130)I and (131)I were first employed to treat thyrotoxicosis by 1941, and thyroid cancer in 1943. After World War II, (131)I became widely available at a reasonable price for diagnostic testing and therapy. The rectilinear scanner of Cassen and Curtis (Science 1949;110:94-95), and a dedicated gamma camera invented by Anger (Nature 1952;170:200-201), finally permitted the diagnostic imaging of thyroid disease, with (131)I again the radioisotope of choice, although there were short-lived attempts to employ (125)I and (132)I for this purpose. (123)I was first produced in 1949 but did not become widely available until about 1982, 10 years after a production technique eliminated high-energy (124)I contamination. I continues to be the radioiodine of choice for the diagnosis of benign thyroid disease, whereas (123)I and (131)I are employed in the staging and detection of functioning thyroid cancer. (124)I, a positron emitter, can produce excellent anatomically correlated images employing positron emission tomography/computed tomography equipment and has the potential to enhance heretofore imperfect dosimetric studies in determining the appropriate administered activity to ablate/treat thyroid cancer. Issues of acceptable measuring error in thyroid cancer dosimetry and the role in (131)I therapy of tumor heterogeneity, tumor hypoxia, and

    This book provides a description of advanced multi-agent and artificial intelligence technologies for the modeling and simulation of complex systems, as well as an overview of the latest scientific efforts in this field. A complex system features a large number of interacting components, whose aggregate activities are nonlinear and self-organized. A multi-agent system is a group or society of agents which interact with others cooperatively and/or competitively in order to reach their individual or common goals. Multi-agent systems are suitable for modeling and simulation of complex systems, which is difficult to accomplish using traditional computational approaches.

    Methodological Guidelines for Modeling and Developing MAS-Based SimulationsThe intersection of agents, modeling, simulation, and application domains has been the subject of active research for over two decades. Although agents and simulation have been used effectively in a variety of application domains, much of the supporting research remains scattered in the literature, too often leaving scientists to develop multi-agent system (MAS) models and simulations from scratch. Multi-Agent Systems: Simulation and Applications provides an overdue review of the wide ranging facets of MAS simulation, i

  20. Agent-Based Negotiation in Uncertain Environments

    Debenham, John; Sierra, Carles

    An agent aims to secure his projected needs by attempting to build a set of (business) relationships with other agents. A relationship is built by exchanging private information, and is characterised by its intimacy — degree of closeness — and balance — degree of fairness. Each argumentative interaction between two agents then has two goals: to satisfy some immediate need, and to do so in a way that develops the relationship in a desired direction. An agent's desire to develop each relationship in a particular way then places constraints on the argumentative utterances. The form of negotiation described is argumentative interaction constrained by a desire to develop such relationships.

  1. Toddlers Selectively Help Fair Agents

    Full Text Available Previous research showed that infants and toddlers are inclined to help prosocial agents and assign a positive valence to fair distributions. Also, they expect that positive and negative actions directed toward distributors will conform to reciprocity principles. This study investigates whether toddlers are selective in helping others, as a function of others’ previous distributive actions. Toddlers were presented with real-life events in which two actresses distributed resources either equally or unequally between two puppets. Then, they played together with a ball that accidentally fell to the ground and asked participants to help them to retrieve it. Participants preferred to help the actress who performed equal distributions. This finding suggests that by the second year children’s prosocial actions are modulated by their emerging sense of fairness.HighlightsToddlers (mean age = 25 months are selective in helping distributors.Toddlers prefer helping a fair rather than an unfair distributor.Toddlers’ selective helping provides evidence for an early sense of fairness.

    The potential role of viruses in coral disease has only recently begun to receive attention. Here we describe our attempts to determine whether viruses are present in thermally stressed corals Pavona danai, Acropora formosa and Stylophora pistillata and zoanthids Zoanthus sp., and their zooxanthellae. Heat-shocked P. danai, A. formosa and Zoanthus sp. all produced numerous virus-like particles (VLPs) that were evident in the animal tissue, zooxanthellae and the surrounding seawater; VLPs were also seen around heat-shocked freshly isolated zooxanthellae (FIZ) from P. danai and S. pistillata. The most commonly seen VLPs were tail-less, hexagonal and about 40 to 50 nm in diameter, though a diverse range of other VLP morphotypes (e.g. rounded, rod-shaped, droplet-shaped, filamentous) were also present around corals. When VLPs around heat-shocked FIZ from S. pistillata were added to non-stressed FIZ from this coral, they resulted in cell lysis, suggesting that an infectious agent was present; however, analysis with transmission electron microscopy provided no clear evidence of viral infection. The release of diverse VLPs was again apparent when flow cytometry was used to enumerate release by heat-stressed A. formosa nubbins. Our data support the infection of reef corals by viruses, though we cannot yet determine the precise origin (i.e. coral, zooxanthellae and/or surface microbes) of the VLPs seen. Furthermore, genome sequence data are required to establish the presence of viruses unequivocally.

    Selenium (Se) compounds are potential therapeutic agents in cancer. Importantly, the biological effects of Se compounds are exerted by their metabolites, with methylselenol (CH₃SeH) being one of the key executors. In this study, we developed a new series of methylselenoesters with different scaffolds aiming to modulate the release of CH₃SeH. The fifteen compounds follow Lipinski's Rule of Five and with exception of compounds 1 and 14 , present better drug-likeness values than the positive control methylseleninic acid. The compounds were evaluated to determine their radical scavenging activity. Compound 11 reduced both DPPH and ABTS radicals. The cytotoxicity of the compounds was evaluated in a panel of five cancer cell lines (prostate, colon and lung carcinoma, mammary adenocarcinoma and chronic myelogenous leukemia) and two non-malignant (lung and mammary epithelial) cell lines. Ten compounds had GI 50 values below 10 μM at 72 h in four cancer cell lines. Compounds 5 and 15 were chosen for further characterization of their mechanism of action in the mammary adenocarcinoma cell line due to their similarity with methylseleninic acid. Both compounds induced G₂/M arrest whereas cell death was partially executed by caspases. The reduction and metabolism were also investigated, and both compounds were shown to be substrates for redox active enzyme thioredoxin reductase.

    Full Text Available Unlike human immunodeficiency virus (HIV and hepatitis B virus (HBV, hepatitis C virus (HCV infection is a curable disease. Current direct antiviral agent (DAA targets are focused on HCV NS3/4A protein (protease, NS5B protein (polymerase and NS5A protein. The first generation of DAAs includes boceprevir and telaprevir, which are protease inhibitors and were approved for clinical use in 2011. The cure rate for genotype 1 patients increased from 45% to 70% when boceprevir or telaprevir was added to standard PEG-IFN/ribavirin. More effective and less toxic second generation DAAs supplanted these drugs by 2013. The second generation of DAAs includes sofosbuvir (Sovaldi, simeprevir (Olysio, and fixed combination medicines Harvoni and Viekira Pak. These drugs increase cure rates to over 90% without the need for interferon and effectively treat all HCV genotypes. With these drugs the “cure HCV” goal has become a reality. Concerns remain about drug resistance mutations and the high cost of these drugs. The investigation of new HCV drugs is progressing rapidly; fixed dose combination medicines in phase III clinical trials include Viekirax, asunaprevir+daclatasvir+beclabuvir, grazoprevir+elbasvir and others.

  6. Departments as Agents of Change

    Higher education is changing because it has no choice. And, for the most part, outside influences are dictating the processes of change. The more fortunate institutions have had a flat budget during this period, but most have been forced to deal with a declining revenue stream as well. Legislators seem bent on micromanaging state-supported institutions, even as they cut their support. Regulators demand greater institutional accountability. Students and their parents expect more service at lower prices and increased flexibility. Technological advances have dramatically affected the availability and accessibility of extant knowledge. It is no longer a question of whether institutions will change, but rather, who will control the change. Most institutions possess long-standing academic traditions, but these are placed at risk in an increasingly competitive market that holds little sympathy for such traditions and may even see them as obstacles or barriers. As a result, the change agents will undoubtedly have a profound effect on the very nature of academic institutions. From the academic point of view, it would seem prudent to attempt to manage the changes that will inevitably occur. A number of concerned observers, notably the Pew Higher Education Roundtable and the American Association for Higher Education, argue persuasively that the academic department is the logical focus for responding to the current winds of change. Using a marketing metaphor, the academic department has been likened to a "producers' cooperative" of services that consumers seek. Thus, the department should be held accountable for the quality of teaching delivered by its members, for the coherence of its major, for its contributions to the general education curriculum, and for supervising and rewarding its individual faculty members. If departments are to be held accountable, it is surely in their best interest to act in such a way that they are accountable. Expecting academic departments to be

    In any patient with uveitis, an infectious cause should be ruled out first. The differential diagnosis includes multiple well-known diseases including herpes, syphilis, toxoplasmosis, tuberculosis, bartonellosis, Lyme disease, and others. However, clinician should be aware of emerging infectious agents as potential causes of systemic illness and also intraocular inflammation. Air travel, immigration, and globalization of business have overturned traditional pattern of geographic distribution of infectious diseases, and therefore one should work locally but think globally. This review recapitulates the systemic and ocular manifestations of several emergent infectious diseases relevant to the ophthalmologist including Rickettsioses, West Nile virus infection, Rift valley fever, Dengue fever, and Chikungunya. Retinitis, chorioretinitis, retinal vasculitis, and optic nerve involvement have been associated with these emergent infectious diseases. The diagnosis of any of these infections is usually based on pattern of uveitis, systemic symptoms and signs, and specific epidemiological data and confirmed by detection of specific antibody in serum. A systematic ocular examination, showing fairly typical fundus findings, may help establish an early clinical diagnosis, which allows prompt, appropriate management.

Data collection was performed by means of semi-structured interviews. The data were analyzed based on the technique of thematic content analysis. RESULTS: In the postnatal period, care needs to be doubled, as it affects mother and child, besides the body vulnerability, which is open to diseases. In articulation with these ideas, the recommendations and restrictions as components of postpartum care are justified. CONCLUSION: Care in the puerperal phase is a feminine practice filled with beliefs and taboos that grants women with power of agents in this process, since she bears the knowledge of many generations at the same time that they act as subjects and reinvent the previously established systems, constructing themselves as mothers.OBJETIVO: Identificar los significados del cuidado en la fase puerperal en el contexto familiar.

  18. Ultrasound contrast agents: An overview

    International Nuclear Information System (INIS)

    Cosgrove, David

    2006-01-01

    With the introduction of microbubble contrast agents, diagnostic ultrasound has entered a new era that allows the dynamic detection of tissue flow of both the macro and microvasculature. Underpinning this development is the fact that gases are compressible, and thus the microbubbles expand and contract in the alternating pressure waves of the ultrasound beam, while tissue is almost incompressible. Special software using multiple pulse sequences separates these signals from those of tissue and displays them as an overlay or on a split screen. This can be done at low acoustic pressures (MI < 0.3) so that the microbubbles are not destroyed and scanning can continue in real time. The clinical roles of contrast enhanced ultrasound scanning are expanding rapidly. They are established in echocardiography to improve endocardial border detection and are being developed for myocardial perfusion. In radiology, the most important application is the liver, especially for focal disease. The approach parallels that of dynamic CT or MRI but ultrasound has the advantages of high spatial and temporal resolution. Thus, small lesions that can be indeterminate on CT can often be studied with ultrasound, and situations where the flow is very rapid (e.g., focal nodular hyperplasia where the first few seconds of arterial perfusion may be critical to making the diagnosis) are readily studied.

    With the introduction of microbubble contrast agents, diagnostic ultrasound has entered a new era that allows the dynamic detection of tissue flow of both the macro and microvasculature. Underpinning this development is the fact that gases are compressible, and thus the microbubbles expand and contract in the alternating pressure waves of the ultrasound beam, while tissue is almost incompressible. Special software using multiple pulse sequences separates these signals from those of tissue and displays them as an overlay or on a split screen. This can be done at low acoustic pressures (MI<0.3) so that the microbubbles are not destroyed and scanning can continue in real time. The clinical roles of contrast enhanced ultrasound scanning are expanding rapidly. They are established in echocardiography to improve endocardial border detection and are being developed for myocardial perfusion. In radiology, the most important application is the liver, especially for focal disease. The approach parallels that of dynamic CT or MRI but ultrasound has the advantages of high spatial and temporal resolution. Thus, small lesions that can be indeterminate on CT can often be studied with ultrasound, and situations where the flow is very rapid (e.g., focal nodular hyperplasia where the first few seconds of arterial perfusion may be critical to making the diagnosis) are readily studied. Microbubbles linger in the extensive sinusoidal space of normal liver for several minutes whereas they wash out rapidly from metastases, which have a low vascular volume and thus appear as filling defects. The method has been shown to be as sensitive as three-phase CT.

    Conclusions : A review of the evolution of topical hemostatic agents highlights opportunities for potential novel research. Fibrin sealants may have the most opportunity for advancement, and understanding the history of these products is useful. With the drive in urology for minimally invasive surgical techniques, adaptation of topical hemostatic agents to this surgical approach would be valuable and offers an opportunity for novel contributions.

  5. Dynamics of three-agent games

    Mungan, Muhittin; Rador, Tonguc

    2008-01-01

    We study the dynamics and resulting score distribution of three-agent games where after each competition a single agent wins and scores a point. A single competition is described by a triplet of numbers p, t and q denoting the probabilities that the team with the highest, middle or lowest accumulated score wins. The three-agent game can be regarded as a social model where a player can be favored or disfavored for advancement, based on his/her accumulated score. We study the full family of solutions in the regime, where the number of agents and competitions is large, which can be regarded as a hydrodynamic limit. Depending on the parameter values (p, q, t), we find six qualitatively different asymptotic score distributions and we provide a qualitative explanation of these results. We also compare our analytical results against numerical simulations of the microscopic model and find these to be in excellent agreement. It is possible to decide the outcome of a three-agent game through a mini-tournament of two-agent competitions among the participating players and it turns out that the resulting possible score distributions are a subset of those obtained for the general three-agent games. We discuss how one can add a steady and democratic decline rate to the model and present a simple geometric construction that allows one to obtain the score evolution equations for n-agent games

    Our vision of the future of information systems is one that includes engineered collectives of software agents which are situated in an environment over years and which increasingly improve the performance of the overall system of which they are a part. At a minimum, the movement of agent and multi-agent technology into National Security applications, including their use in information assurance, is apparent today. The use of deliberative, autonomous agents in high-consequence/high-security applications will require a commensurate level of protection and confidence in the predictability of system-level behavior. At Sandia National Laboratories, we have defined and are addressing a research agenda that integrates the surety (safety, security, and reliability) into agent-based systems at a deep level. Surety is addressed at multiple levels: The integrity of individual agents must be protected by addressing potential failure modes and vulnerabilities to malevolent threats. Providing for the surety of the collective requires attention to communications surety issues and mechanisms for identifying and working with trusted collaborators. At the highest level, using agent-based collectives within a large-scale distributed system requires the development of principled design methods to deliver the desired emergent performance or surety characteristics. This position paper will outline the research directions underway at Sandia, will discuss relevant work being performed elsewhere, and will report progress to date toward assurance in agent-based systems.

    The primary goal of this book is to present the research findings and conclusions of physicists, economists, mathematicians and financial engineers working in the field of "Econophysics" who have undertaken agent-based modelling, comparison with empirical studies and related investigations. Most standard economic models assume the existence of the representative agent, who is “perfectly rational” and applies the utility maximization principle when taking action. One reason for this is the desire to keep models mathematically tractable: no tools are available to economists for solving non-linear models of heterogeneous adaptive agents without explicit optimization. In contrast, multi-agent models, which originated from statistical physics considerations, allow us to go beyond the prototype theories of traditional economics involving the representative agent. This book is based on the Econophys-Kolkata VII Workshop, at which many such modelling efforts were presented. In the book, leading researchers in the...

    Software agents are particularly suitable for engineering models and simulations of cellular systems. In a very natural and intuitive manner, individual software components are therein delegated to reproduce "in silico" the behavior of individual components of alive systems at a given level of resolution. Individuals' actions and interactions among individuals allow complex collective behavior to emerge. In this chapter we first introduce the readers to software agents and multi-agent systems, reviewing the evolution of agent-based modeling of biomolecular systems in the last decade. We then describe the main tools, platforms, and methodologies available for programming societies of agents, possibly profiting also of toolkits that do not require advanced programming skills.

  9. Fault Reconnaissance Agent for Sensor Networks

    2010-01-01

    Full Text Available One of the key prerequisite for a scalable, effective and efficient sensor network is the utilization of low-cost, low-overhead and high-resilient fault-inference techniques. To this end, we propose an intelligent agent system with a problem solving capability to address the issue of fault inference in sensor network environments. The intelligent agent system is designed and implemented at base-station side. The core of the agent system – problem solver – implements a fault-detection inference engine which harnesses Expectation Maximization (EM algorithm to estimate fault probabilities of sensor nodes. To validate the correctness and effectiveness of the intelligent agent system, a set of experiments in a wireless sensor testbed are conducted. The experimental results show that our intelligent agent system is able to precisely estimate the fault probability of sensor nodes.

    The development of a number of in vitro techniques for the evaluation of antiplaque effects of test agents has followed the characterization and culturing of plaque-forming microorganisms. Studies of the mechanism of action of chlorhexidine and clinical observations have assisted in defining critical aspects of these in vitro techniques. Such assays may play an increasingly important role in screening potential new agents as well as in the optimization of properties by chemical modification of new lead agents. In addition, data generated in the in vitro assay may assist the design of in vivo evaluations of new agents. Proper selection of in vitro techniques for these various functions in the pre-clinical development process may reduce the time and cost involved in the development of new antiplaque agents.

    2015-04-01

    Within an agent-based model where moral classifications are socially learned, we ask if a population of agents behaves in a way that may be compared with conservative or liberal positions in the real political spectrum. We assume that agents first experience a formative period, in which they adjust their learning style acting as supervised Bayesian adaptive learners. The formative phase is followed by a period of social influence by reinforcement learning. By comparing data generated by the agents with data from a sample of 15000 Moral Foundation questionnaires we found the following. 1. The number of information exchanges in the formative phase correlates positively with statistics identifying liberals in the social influence phase. This is consistent with recent evidence that connects the dopamine receptor D4-7R gene, political orientation and early age social clique size. 2. The learning algorithms that result from the formative phase vary in the way they treat novelty and corroborative information with more conservative-like agents treating it more equally than liberal-like agents. This is consistent with the correlation between political affiliation and the Openness personality trait reported in the literature. 3. Under the increase of a model parameter interpreted as an external pressure, the statistics of liberal agents resemble more those of conservative agents, consistent with reports on the consequences of external threats on measures of conservatism. We also show that in the social influence phase liberal-like agents readapt much faster than conservative-like agents when subjected to changes on the relevant set of moral issues. This suggests a verifiable dynamical criterium for attaching liberal or conservative labels to groups.

A standard online notification form was used to register cases in a database maintained by the Netherlands Center for Occupational Diseases (NCOD. The public health service of Curaçao analyzed the data and presented the results to the participating physicians during educational and feedback meetings. RESULTS: During the study period, 1 519 cases were reported: 720 (47.0% work-related diseases; 515 (34.0% injuries; and 284 (19.0% complaints. The mean patient age was 42.4 years (range 16-70 years; 924 (60.8% were males and 571 (37.6%, females. Most frequently reported were musculoskeletal diseases, injuries, and complaints; mental health disorders; and skin injuries. Analysis showed incidence rates of work-related diseases, injuries, and complaints in Aruba to be 157 new cases per 100 000 employee years; in Bonaire, 53/100 000; and in Curaçao, 437/100 000. CONCLUSIONS: These results suggest that labor protection laws need improvement and that preventive action should be fostered. Further study is needed on working conditions, preventive policy, and the quality of occupational health and safety practices in Aruba, Bonaire, and Curaçao. Funding is imperative for collecting and publishing accurate data, which will keep this problem on the social-political agenda.OBJETIVO: Calcular la incidencia de enfermedades, lesiones y síntomas relacionados con el trabajo en Aruba, Bonaire y Curazao e identificar los pasos siguientes en el proceso de prevención.

    Full Text Available Verificou-se entre os escolares atendidos pela Secretaria Municipal de Educação de Estiva Gerbi-SP, a prevalência de 11,5% de enteroparasitas, que puderam ser relacionados a aspectos socioeconômicos. Realizou-se então uma oficina de trabalho sobre parasitas intestinais no sentido de informar e discutir sobre esta questão, complementando o tratamento médico. Em especial, foi envolvida a Escola Alaíde R. Batista que atende crianças até 4 anos de idade, e que havia mostrado a maior (23,5% taxa de parasitismo. Uma avaliação dois anos após a oficina de trabalho mostrou que a prevalência de enteroparasitas nos escolares tratados foi reduzida, e era de 6,6%. Na escola como um todo, devido ao ingresso de novos estudantes, a prevalência era ainda de 23,3%. Concluiu-se que atitudes educativas são válidas, mas precisam ser integradas a um processo contínuo de educação e controle das enteroparasitoses.

    Acetylcholinesterase is vital for normal operation of many processes in the body. Following exposure to organophosphorus (OP) nerve agents, death can ensue without immediate medical intervention. Current therapies mitigate the cholinergic crisis caused by nerve agents but do not fully prevent long-term health concerns, for example, brain damage following seizures. Human butyrylcholinesterase (HuBChE) is a stoichiometric bioscavenger being investigated as an antidote for OP nerve agent poisoning. HuBChE sequesters OP nerve agent in the bloodstream preventing the nerve agent from reaching critical target organ systems. HuBChE was effective when used as both a pre-treatment and as a post-exposure therapy. HuBChE has potential for use in both military settings and to protect civilian first responders in situations where nerve agent usage is suspected. We reviewed various animal models studies evaluating the efficacy of HuBChE against nerve agent exposure, pursuant to its submission for approval under the FDA Animal Rule. © 2017 Wiley Periodicals, Inc.

  6. Persistent agents in Axelrod's social dynamics model

    Reia, Sandro M.; Neves, Ubiraci P. C.

    2016-01-01

    Axelrod's model of social dynamics has been studied under the effect of external media. Here we study the formation of cultural domains in the model by introducing persistent agents. These are agents whose cultural traits are not allowed to change but may be spread through local neighborhood. In the absence of persistent agents, the system is known to present a transition from a monocultural to a multicultural regime at some critical Q (number of traits). Our results reveal a dependence of critical Q on the occupation probability p of persistent agents and we obtain the phase diagram of the model in the (p,Q) -plane. The critical locus is explained by the competition of two opposite forces named here barrier and bonding effects. Such forces are verified to be caused by non-persistent agents which adhere (adherent agents) to the set of traits of persistent ones. The adherence (concentration of adherent agents) as a function of p is found to decay for constant Q. Furthermore, adherence as a function of Q is found to decay as a power law with constant p.

There is also a Briefing and Response Instruction (BRI) which is easy for a discipline specialist to create through a BRI editor.

  8. Continuum deformation of multi-agent systems

    CERN Document Server

    Rastgoftar, Hossein

    2016-01-01

    This monograph presents new algorithms for formation control of multi-agent systems (MAS) based on principles of continuum mechanics. Beginning with an overview of traditional methods, the author then introduces an innovative new approach whereby agents of an MAS are considered as particles in a continuum evolving in ℝn whose desired configuration is required to satisfy an admissible deformation function. The necessary theory and its validation on a mobile-agent-based swarm test bed are considered for two primary tasks: homogeneous transformation of the MAS and deployment of a random distribution of agents on a desired configuration. The framework for this model is based on homogeneous transformations for the evolution of an MAS under no inter-agent communication, local inter-agent communication, and intelligent perception by agents. Different communication protocols for MAS evolution, the robustness of tracking of a desired motion by an MAS evolving in ℝn, and the effect of communication delays in an MAS...

  9. Relay tracking control for second-order multi-agent systems with damaged agents.

    Science.gov (United States)

    Dong, Lijing; Li, Jing; Liu, Qin

    2017-11-01

    This paper investigates a situation where smart agents capable of sensory and mobility are deployed to monitor a designated area. A preset number of agents start tracking when a target intrudes this area. Some of the tracking agents are possible to be out of order over the tracking course. Thus, we propose a cooperative relay tracking strategy to ensure the successful tracking with existence of damaged agents. Relay means that, when a tracking agent quits tracking due to malfunction, one of the near deployed agents replaces it to continue the tracking task. This results in jump of tracking errors and dynamic switching of topology of the multi-agent system. Switched system technique is employed to solve this specific problem. Finally, the effectiveness of proposed tracking strategy and validity of the theoretical results are verified by conducting a numerical simulation. Copyright © 2017 ISA. Published by Elsevier Ltd.

    2017-01-01

    We investigate the multi-agent pathfinding (MAPF) problem with $n$ agents on graphs with $n$ vertices: Each agent has a unique start and goal vertex, with the objective of moving all agents in parallel movements to their goal s.t.~each vertex and each edge may only be used by one agent at a time....... We give a combinatorial classification of all graphs where this problem is solvable in general, including cases where the solvability depends on the initial agent placement. Furthermore, we present an algorithm solving the MAPF problem in our setting, requiring O(n²) rounds, or O(n³) moves...... of individual agents. Complementing these results, we show that there are graphs where Omega(n²) rounds and Omega(n³) moves are required for any algorithm....

    Alkylating agents are the most widely used anticancer drugs whose main target is the DNA, although how exactly the DNA lesions cause cell death is still not clear. The emergence of resistance to this class of drugs as well as to other antitumor agents is one of the major causes of failure of cancer treatment. This paper reviews some of the best characterized mechanisms of resistance to alkylating agents. Pre- and post-target mechanisms are recognized, the former able to limit the formation of...

    Francisella tularensis is a small, nonmotile, aerobic, gram-negative coccobacillus capable of surviving for weeks at low temperatures in water, moist soil, hay, straw, or decaying animal carcasses. F. tularensis is the causative of the zoonotic disease tularemia. This bacterium was first identified in ground squirrels in Tulare County, California (1912). The human disease was recognized and described by Edward Francis (1922) as tularemia, and the agent was renamed Francisella tularensis in his honor. F. tularensis is one of the most infectious bacterial pathogens known, as few as 10-50 organisms can cause disease. Humans can become incidentally infected through diverse environmental exposures: bites by infected arthropods; handling infectious animal tissues or fluids; direct contact with or ingestion of contaminated food, water, or soil and inhalation of infective aerosols. Humans can develop severe and sometimes fatal illness, but do not transmit the disease to others. F. tularensis have few subspecies: 1) F. tularensis subsp. tularensis (type A), highly virulent, found only in North America. The bacterium is transmitted among animals and from animals to humans by ticks, occasionally deerfly, or by aerosols; 2) F. tularensis subsp. holarctica (type B), moderately virulent, occurs in Euroasia and North America, mainly associated with streams, lakes, ponds, rivers and semi-aquatic animals such as muskrats and beavers (water-borne disease). Type B tularemia has been observed during war times (during Second World War 100 000 cases occurred each year, in Kosovo in 2000 and 2003 over 300 cases each year); 3) F. tularensis subsp. mediasiatica, rarely reported, isolated only in Kazahstan and Turkmenistan; 4) F. tularensis subsp. novicida is of low virulence, isolated in USA, Canada, Spain and Australia; 5) F. tularensis subsp. philomiragia, is of low virulence, associated with salt water (Atlantic, Mediterranean). Tularemia is very rear in Macedonia, but in 1996 an

    We propose a system architecture for mobile agents to improve their security in the environments of insecure networks and non-sophisticated terminals such as PDAs. As mobile agents freely migrate onto their favorite terminals through insecure networks or terminals, it is not appropriate for them to store some secret information for authentication and encryption/decryption. We introduce one and more secure nodes(OASIS NODE) for securely generating and verifying authentication codes. The each agent’s data are encrypted by a pseudo-chaos cipher mechanism which doesn’t need any floating processing co-processor. We’ve constructed a prototype system on a Java mobile agent framework, “Bee-gent" which implements the proposed authentication and cipher mechanisms, and evaluated their performances and their applicability to business fields such as an auction system by mobile agents.
