    Full Text Available Erros humanos são uma importante fonte de falhas em todos os passos do planejamento e do tratamento radioterapêutico. Com o objetivo de reduzir este grau de incerteza, várias organizações especializadas recomendam minuciosos programas de garantia da qualidade. No Brasil, programas deste tipo vêm tendo sua exigência intensificada, e a maioria dos serviços de radioterapia vem se orientando neste sentido, tanto em relação aos equipamentos de radiação e dosimetria, quanto em relação à verificação dos cálculos de dose em pacientes e das revisões das fichas de planejamento. Como uma contribuição a este esforço de qualidade, apresentam-se algumas recomendações para se evitar falhas de tratamento devidas a erros na dose de radiação recebida pelo paciente, como redundância nas verificações dos cálculos feitos manualmente ou por computador, e, também, a verificação da dose acumulada para cada paciente sob tratamento, semanalmente, além de se evitar a possibilidade de acesso a qualquer sistema de segurança do equipamento ao pessoal técnico treinado para apenas o operar. Além disso, deve-se considerar a possibilidade de se empregar um sistema computadorizado de verificação e registro do tratamento, dessa maneira prevenindo-se erros durante a aplicação diária devidos à seleção indevida dos diferentes parâmetros do tratamento. Reportam-se quatro incidentes radioativos recentes ocorridos no mundo, com injúrias em pacientes, e algumas ocorrências de erros grandes de dose.Human mistakes are an important source of errors in radiotherapy and may occur at every step of the radiotherapeutic planning and treatment. To reduce this level of uncertainties, several specialized organizations have recommended a comprehensive quality assurance program. In Brazil, the requirement for these programs has been strongly stressed, and most radiotherapy services have pursued this goal regarding radiation units and dosimetry equipment

    Full Text Available OBJETIVOS: Descrever e analisar a prevalência de erros refrativos em estudantes de primeira série das escolas estaduais de Passo Fundo, cidade pólo da região Nordeste do Rio Grande do Sul. MÉTODOS: Estudo transversal de 1608 alunos da primeira série do ensino fundamental de 26 escolas estaduais de Passo Fundo, atendidas em 2004. Os dados foram coletados no CEAE (Centro Especializado de Assistência ao Educando, que fez a triagem nas escolas, e no serviço especializado, para onde foram encaminhados aqueles com testes alterados. RESULTADOS: Da amostra total, 172 (10,88% apresentaram baixa de acuidade visual ou algum sintoma de problema visual, recebendo encaminhamento para atendimento oftalmológico. Apenas 88 (51,16% dos encaminhados compareceram à consulta. A média de idade foi de 7,10 anos (DP= 1,38. Entre as crianças examinadas, 70,46% possuíam algum erro refracional, sendo a hipermetropia e o astigmatismo os mais comuns (encontrado em 45,45% e 10,23% dos alunos examinados, respectivamente. A miopia foi o erro refracional menos prevalente, presente em 10,23% dos escolares atendidos. CONCLUSÃO: O estudo mostrou prevalência de 3,92% de erros refrativos na população de escolares estudada, embora a abstenção elevada possa estar subestimando esse percentual. Percebe-se a necessidade da realização de programas que enfoquem uma maior adesão dos alunos ao encaminhamento, na tentativa de evitar o não diagnóstico de problemas oculares facilmente tratáveis na infância.OBJECTIVES: To describe and analyze the prevalence of refractive errors among first-graders in state schools of Passo Fundo, main city of the northeast region of Rio Grande do Sul State.

    Full Text Available A ideia de que erros bizarros podem conduzir a grandes acertos não é estranha à história da ciência. Este artigo examina o esforço realizado por Wolfgang Schluchter no sentido de mostrar que um determinado erro de Max Weber conduziu a um grande acerto – em razão de ter sido produzido nos marcos de uma perspectiva metateórica que conduz erros a acertos, a perspectiva “histórico-desenvolvimental” (Entwicklungsgeschichte. O erro: aplicar o conceito de “povo-pária” aos judeus da Antiguidade. Argumento de Schluchter: os historiadores mostraram que o conceito de “povo-pária” não se aplica aos judeus da Antiguidade, mas, não obstante, vale a pena insistir nesse erro porque ele conduz a um grande acerto: mostrar a importância da ruptura efetuada pelas missões Paulinas (com o particularismo judaico para o desenvolvimento do racionalismo ocidental. Argumento do artigo: isto que Schluchter considera o grande acerto é apenas uma reverberação do pensamento teológico protestante do século XIX.

    Full Text Available El presente artículo se enmarca dentro de la caracterización del sistema de producción bovina del municipio de Utica (Cundinamarca y dentro de los problemas más importantes que lo afectan. Como resultado, el estudio identificó la escasez de alimento de buena calidad en épocas secas como la principal limitante del productor bovino del municipio. Aprovechando una ventaja presente en la zona, como es la elaboración de panela (proceso a través del cual resultan algunos subproductos, como bagazo y melote, que pueden ser utilizados como alternativa alimenticia para los bovinos en cualquier época del año, se planteó un experimento en el que se elaboraron bloques multinutricionales con base en dichos subproductos. El experimento se adelantó en una finca de un productor y se utilizaron 57 novillos cebús con edades entre los 11 y los 24 meses y pesos entre los 124 y los 463 kilogramos. Los animales se dividieron dos grupos que se mantuvieron en pasturas no manejadas. Al grupo experimental se le ofrecieron adicionalmente bloques multinutricionales. Los animales fueron examinados para comprobar su estado fisiológico, con el fin de determinar posibles inconvenientes sanitarios que pudieran afectar el ensayo. Se realizaron pesajes para medir las ganancias de peso en los dos grupos. Los resultados mostraron promedios de ganancias diarias de peso similares a Pr < 5%, donde fueron ligeramente superiores las del grupo alimentado con los bloques multinutricionales (0,848 vs. 0,769 kg animal/día. Los aportes más importantes del experimento fueron, primero, brindar una opción para que el productor pueda alimentar a sus animales en épocas de escasez y evitar que tenga que venderlos a bajos precios. El segundo aporte fue abrir la posibilidad de usar los productos de la elaboración de la panela, que en muchas ocasiones se convierten en desechos que no son usados y que contaminan las fuentes de agua, de una forma económicamente viable.

    Full Text Available Objetivo: o presente artigo tem por objetivo revisar a literatura e discutir a questão do erro médico em pacientes hospitalizados, enfocando sua conceituação, incidência, fatores predisponentes e mecanismos de prevenção. Aborda, em especial, erros e eventos adversos com drogas envolvendo recém-nascidos e pacientes pediátricos. Métodos: revisão bibliográfica utilizando banco de dados Medline, selecionando-se aqueles com informações atuais e relevantes. Resultados:mesmo assumindo que a notificação do erro médico não ocorre em um grande número de eventos, é importante notar que sua incidência é muito maior do que julgamos. Só nos EUA, cerca de um milhão de pacientes por ano são vítimas de erros médicos e eventos adversos com drogas. Segundo recente metanálise, esta é, hoje, a quarta causa de morte nos EUA. Em unidades de terapia intensiva neonatal e pediátrica, nas quais é grande a complexidade e a freqüência de procedimentos, a ocorrência de erros é maior. Estima-se que quinze por cento das internações em unidades de terapia intensiva neonatal sejam acompanhadas de erro médico. A maioria destes erros acontece durante o período noturno, e envolve administração incorreta de droga (35% e erro na interpretação da prescrição (26%. Fatores ambientais (barulho, calor, psicológicos (tédio, ansiedade, estresse e fisiológicos (fadiga, sono contribuem para a ocorrência de erros. Recente estudo revela que após um plantão de 24 horas, sem dormir, o desempenho psicomotor de um profissional de saúde é semelhante ao de um indivíduo legalmente bêbado (nível sérico alcoólico maior ou igual a 0,08%! Conclusões: mesmo em profissionais conscientes, erros são acompanhantes inevitáveis da condição humana. A prevenção de erros deve basear-se na busca de causas reais, que geralmente incluem erros no sistema de organização e implementação do serviço. Erros devem ser aceitos como evidência de falha no

    Full Text Available O presente estudo propõe-se a identificar a prevalência do acesso a informações sobre como evitar problemas bucais entre escolares da rede pública de ensino, assim como os fatores associados a este acesso. Trata-se de um estudo transversal e analítico conduzido entre escolares de 12 anos de idade de um município brasileiro de grande porte populacional. Os exames foram realizados por 24 cirurgiões-dentistas treinados e calibrados com auxilio de 24 anotadores. A coleta de dados ocorreu em 36 escolas sorteadas das 89 escolas públicas do município. Foram conduzidas análises descritivas, univariadas e múltiplas. Dos 2510 escolares incluídos no estudo, 2211 relataram já ter recebido informações sobre como evitar problemas bucais. O acesso a tais informações foi maior entre os que utilizaram serviços odontológicos privado/convênio; e menor entre aqueles que utilizaram o serviço para tratamento, os que avaliaram o serviço como regular ou ruim/péssimo, os que utilizam como meio de higiene bucal somente escova dente/escova dente e higienização a língua e os que relataram não estarem satisfeitos com a aparência de seus dentes. Conclui-se que a maioria dos escolares teve acesso a informações sobre como evitar problemas bucais, o qual esteve associado a características dos serviços de saúde, comportamentos e desfechos de saúde.

    Full Text Available Estudo descritivo exploratório com objetivo de verificar a taxa de erros em prescrições médicas coletadas em uma drogaria privada. Durante 30 dias foram coletadas 120 prescrições e analisadas as variáveis legibilidade, identificação do prescritor e paciente, dose e posologia, abreviaturas, e adequação à legislação. No total, foram identificados 426 erros. Os erros mais frequentes foram prescrições ilegíveis ou pouco legíveis 68,33%, identificação do prescritor incompleta ou omissa 10%, identificação do paciente incompleta ou omissa 42,5%, posologia incompleta ou omissa 40%, dose incompleta ou omissa 45%, presença de abreviaturas 84,17%, e 65% das prescrições não cumpriram de forma adequada com a legislação. Foi observada elevada taxa de erros nas prescrições analisadas, demonstrando a necessidade da avaliação do farmacêutico para a detecção destes erros, solicitação de correções e prevenção do risco de exposição do paciente aos problemas ocasionados por esses erros tais como reações adversas, interações medicamentosas, intoxicações, agravamento de doenças ou óbito. Ademais, é necessária a conscientização para o cumprimento das boas práticas de prescrição e sugere-se a realização de estudos para elaborar estratégias que minimizem a ocorrência de erros de prescrição.

    In order to consider some procedures to prevent errors in radiotherapy based in learned lessons of accidental expositions and in accordance with information contained in international reports elaborated by International Atomic Energy Agency (IAEA) and of the data base availability by the European group Radiation Oncology Safety Information System (ROSIS) on the events, a research of the occurred errors was performed. For the evaluation of the incidents a data base based in the ROSIS and added plus a parameter was created 'type of error'. All the stored data make possible the evaluation of the 839 incidents in terms of frequency of the type of error, the process of detention, the number of reached patients and the degree of severity. Of the 50 types of found errors, the type of error more frequently was 'incorrect treatment coordinate', confirmed with the data of literature and representing 28,96 por cent of the total of the incidents. The results showed 44,44 por cent are discovered at the moment of the treatment and that the process of verification of the fiche or clinical revision of the patient is a verification more occurred insurance and in 43,33 por cent of the searched events. The results indicated that more than 50 por cent of the incidents the severity degree are void and approximately 62 por cent a patient are affected during the accomplishment of the radiotherapy. This work showed that to analyze the data base according to methodology proposal for Klein et al.; for Reason, and Dunscombe et al. is interesting to insert more characteristic detailed in the data base such as: the number of fractions for affected patient, number of fields of treatment for fraction that was affected, shunting line of the prescribed dose and shunting line of the volume prescribed in all the registered in cadastral map events. Some causes exist that can lead the errors when patient they are submitted to the radiotherapy. Some measures can be taken so that these errors do not occur as: to carry through dosimetry in vivo 'off-axis' with diode to reduce the use of the incorrect direction of the wedge; to use values of the vertical distance with pointer of optic distance (SSD) to prevent error of distance of treatment; to use the system of transference of data DICOM-RT between the stations of work of the planning of treatment and the simulation, being increased the efficiency and accuracy in the treatment; to manually consider the redundancy in the verifications of the calculations carried through for computer or; to use a computerized system of register and verification of the treatment; preventing errors in the which had daily treatments to the incorrect election of the treatment parameters; to implant a magnetic card of identification of the patient with photo, identification number, name of the institution, name of the department, the date of the first emission and responsible doctor to prevent errors of identification and register and could all be used in the process of the treatment. Of this form, these procedures can prevent incident more in radiotherapy and increase the security of the patients. (author)

    Females of several species of dipteran parasitoids use long-range hearing to locate hosts for their offspring by eavesdropping on the acoustic mating calls of other insects. Males of these acoustic eavesdropping parasitoids also have physiologically functional ears, but so far, no adaptive function for male hearing has been discovered. I investigated the function of male hearing for the sarcophagid fly Emblemasoma erro Aldrich, an acoustic parasitoid of cicadas, by testing the hypothesis that both male and female E. erro use hearing to locate potential mates. I found that both male and nongravid female E. erro perform phonotaxis to the sounds of calling cicadas, that male flies engage in short-range, mate-finding behavior once they arrive at a sound source, and that encounters between females and males at a sound source can lead to copulation. Thus, cicada calling songs appear to serve as a mate-finding cue for both sexes of E. erro Emblemasoma erro's mate-finding behavior is compared to that of other sarcophagid flies, other acoustic parasitoids, and nonacoustic eavesdropping parasitoids. © The Author 2016.

    ísticamente representativa do total de consultas médicas realizadas no período de um ano. A validade da prescrição médica foi feita utilizando as seguintes variáveis: indicação, doses recomendada, via de administração, contra-indicações, interações, duplicação de medicamentos, medicamentos desnecessários ou faltantes. As prescrições médicas foram classificadas como: apropriada (se não foram encontrados erros nas prescrições ou inapropriada (se foram encontradas ao menos um erro na prescrição. A razão risco-beneficio foi calculada para cada prescrição médica. O estudo revelou alta incidência de prescrições inapropriadas no Centro de Saúde da Universidade do México (58%, causada pelos erros nas doses recomendadas e na seleção do medicamento relacionado com a necessidade do paciente. Como resultado da análise chi2 , foi encontrado que as variáveis fármaco-terapêuticas escolhidas neste estudo para avaliar a prescrição médica, foram determinantes para classificar as prescrições como apropriadas. Nimesulide, ciprofloxacin, ranitidine, ketorolac e paracetamol representaram o maior número de medicamentos prescritos assim como a maior causa de erros encontradas nas prescrições. É importante que um farmacêutico valide os medicamentos prescritos no Centro de Saúde. Este estudo justifica o papel que os farmacêuticos mexicanos deveriam desempenhar para evitar erros na prescrição, como parte importante da equipe médica, assim como a urgência de implementar os cuidados farmacêuticos em todos os estabelecimentos dos Centros de Saúde no México.

    Females of several species of dipteran parasitoids use long-range hearing to locate hosts for their offspring by eavesdropping on the acoustic mating calls of other insects. Males of these acoustic eavesdropping parasitoids also have physiologically functional ears, but so far, no adaptive function for male hearing has been discovered. I investigated the function of male hearing for the sarcophagid fly Emblemasoma erro Aldrich, an acoustic parasitoid of cicadas, by testing the hypothesis that...

    Subduction zones represent a unique feature of the dynamic Earth and provide important constraints on how plate tectonics works. Subduction of serpentinized oceanic lithosphere, characterized by releasing water into the mantle wedge via dehydration, i.e. breakdown of hydrous minerals, plays a critical role in not only the generation of continental crust but also the Earth's water cycle. To track the recycling of water or fluid released by subduction, the stable isotope system of Li, a lithophile and mobile element, shows its high potential because 7Li, relative to 6Li, preferentially moves into the fluid phase when fractionation occurs. Here we present new Li abundance and isotopic compositions of the Erro-Tobbio serpentinized peridotite complex, a remnant mantle slice of the Alpine subduction. Our data indicate that most of the serpentinized ultramafic rocks have uniform Li concentrations, around 1 ppm. These rocks, however, show variable Li isotopic compositions. Among them, the high-pressure antigorite-bearing metaperidotites, formed under a low-strain condition, have a limited range in Li isotopic values, with δ7Li = +1.5 to +4.0, similar to those of serpentinized peridotites. In contrast, apparently heavier Li isotopes, up to +10.0, are observed in the high-pressure serpentinite mylonites that also contain antigorite but formed in high-strain domains. We note that O-H isotope ratios of the high-pressure ultramafic rocks reported in previous study (Früh-Green et al., 2001, Contrib. Mineral Petrol. 141: 145-159) show insignificant variations between the low- and high-strain domains. This demonstrates the superiority of Li isotope than conventional stable isotope systems in offering critical information about fluid-releasing processes in subduction zones. Moreover, our new data unsupport the general assumption that fluid released from subducted slabs is in favor of extracting 7Li than 6Li, thus capable of forming the much lighter δ7Li values observed in

    2005-01-01

    Full Text Available Los animales viven en ambientes donde está presente, de manera permanente, la amenaza de enfermar. Para evitarlo, se alimentan lejos de las heces y reconocen las plantas o zonas del potrero que deben evitar. Aprenden, también, a ingerir especies o realizar conductas específicas con fines profilácticos. Si esto falla, entonces el animal manifiesta otras conductas y respuestas fisiológicas como: anorexia, inactividad, dolor y fiebre. El dolor obliga al animal a proteger el área dañada, evitando el apoyar una pata herida o inutilizando un músculo dañado, mientras los tejidos son reparados. La fiebre representa un alto costo energético, y para ahorrar energía, el animal tiende a permanecer inmóvil, estrategia de gran utilidad para controlar el crecimiento y reproducción de bacterias patógenas. En el comportamiento de los animales enfermos se han descubierto sustancias involucradas denominadas citocinas, que juegan un papel muy importante en la inducción de este tipo de conductas; por ejemplo, se puede inducir una disminución del consumo de alimento y en la actividad física inyectando sustancias provenientes de paredes celulares de bacterias o determinadas toxinas. El conocimiento de la conducta y sus bases fisiológicas en la lucha contra la enfermedad ofrecen expectativas prometedoras en la investigación para mejorar el diagnóstico y tratamiento de enfermedades

    Full Text Available Solos com umidade ótima de compactação menor que a capacidade de campo e solos com má drenagem são mais propensos a serem compactados nas operações de exploração florestal. O conhecimento dessas variáveis permite classificar os solos quanto à sua suscetibilidade à compactação, no entanto essas determinações demandam tempo, recursos e equipamentos específicos. Utilizando 13 solos florestais com ampla variação textural, das fazendas Ariona e Santa Rosa pertencentes à Cia. Suzano de Papel e Celulose, situadas no Estado de São Paulo, desenvolveu-se um índice, denominado diâmetro médio ponderado de partículas, que permitiu estimar a umidade ótima de compactação, a capacidade de campo e o limite líquido baseado apenas na distribuição de tamanho de partículas. Com base nessas características físicas e no consumo médio diário de água de um plantio de eucalipto, foram estabelecidas unidades de colheita a partir do número de dias de repouso necessários para o teor de água de um solo ficar abaixo da umidade ótima de compactação. Tais unidades agrupam solos que precisam do mesmo número de dias após uma chuva (0 a 10 dias para poderem ser explorados, visando diminuir o impacto da colheita florestal e, em consequência, evitar a necessidade de preparo do solo para diminuir a compactação provocada por essas operações.

    Full Text Available A very common problem, that occurs during the electrochemical pitting corrosion tests of CRAs (corrosion resistant alloys as stainless steels, is the simultaneous occurrence of crevice corrosion that difficults the evaluation of the electrochemical behaviour in presence of pitting corrosion mechanism only. Crevice corrosion appears as a consequence of the formation of crevices during the mountage of the specimen in the electrochemical cell. Several forms have been developed to avoid the presence of crevice during the electrochemical pitting corrosion test, but without satisfactory results. In the present study a relatively new and innovative method to eliminate the risk of crevice corrosion in the electrochemical tests is evaluated the Avesta cell. Anodic polarization electrochemical tests were carried out in a high alloy stainless steel in 3 % NaCl solution. The experimental results obtained using the Avesta cell were more reliable, reproducible and representative of the electrochemical behaviour of the material that those obtained using other methods of samples preparation to avoid the crevice formation.

    Uno de los grandes problemas que suelen presentarse en los ensayos electroquímicos ideados para evaluar la resistencia a la corrosión por picaduras de materiales como los aceros inoxidables es la presencia simultánea de corrosión por resquicios, que suele dificultar e impedir muchas veces la interpretación de los resultados electroquímicos. Este mecanismo de corrosión localizada se produce como consecuencia de la presencia de resquicios en el ensamble de la muestra con la celda electroquímica de ensayo. Se han ideado numerosas formas de evitar este inconveniente, pero ninguna ha resultado completamente satisfactoria. En el presente estudio se evalúa uno de los más nuevos e ingeniosos procedimientos para eliminar el riesgo de corrosión por resquicios en los ensayos de corrosión por picaduras: la celda Avesta.

    Full Text Available Dentre os indicadores de saúde tradicionalmente utilizados a mortalidade infantil destaca-se como um dos mais importantes. Frequentemente é utilizada por profissionais de saúde pública na caracterização do nível de saúde e em avaliações de programas. Existem, porém, vários fatores de erros que afetam o seu valor e dentre esses são destacados: a definição dos nascidos vivos e sua aplicação na prática, o sub-registro de óbito e de nascimento, o registro do óbito por local de ocorrência, a definição de nascido vivo no ano e a declaração errada na idade. Existem também erros qualitativos que dizem respeito, principalmente, a declarações erradas da causa de morte. Vários desses fatores foram medidos para São Paulo.Among the traditionally used health indices the infant mortality rate is distinguished as the most important one. Frequently it is used by the public health professionals for health level characterization and for the evaluation of programmes. There are, however, several error factors that affect its value, among which are the live birth definition and its true use; underregistration of deaths and births; the death register by place of occurrence; live birth definition in the year, and the wrong age information. There are also qualitative errors due to wrong information as regards the causes of death. Several of these factors were discussed for S. Paulo.

    We discuss new-type grand unified theories based on grand unified groups broken into their special subgroups, as well as their regular subgroups. In the framework, when we construct 4-dimensional (4D) chiral gauge theories, i.e., the Standard Model (SM), 4D gauge anomaly cancelation restricts the minimal number of generations of the 4D SM Weyl fermions. We show that in a 6-dimensional (6D) SU(16) gauge theory on M^4× T^2/\\mathbb{Z}_2, one generation of the SM fermions can be embedded into a 6D bulk Weyl fermion. For the model including 3 chiral generations of the SM fermions, the 6D and 4D gauge anomalies on the bulk and fixed points are canceled out without exotic 4D chiral fermions.

  1. Análise de erros e compreensão de textos: comparações entre diferentes situações de leitura

    Directory of Open Access Journals (Sweden)

    Alina Galvão Spinillo

    Full Text Available O presente estudo analisou os erros apresentados por crianças com dificuldades de compreensão de textos em duas situações de leitura. As crianças do Grupo 1 realizaram a leitura interrompida de uma história e as do Grupo 2 realizaram a leitura sem interrupção. Após a leitura, as crianças responderam perguntas sobre informações inferenciais. A análise das respostas permitiu identificar quatro tipos de erros referentes à maneira de integrar informações intra e extratextuais. Apesar dos erros serem estáveis em ambas as situações, a leitura interrompida propiciou tentativas de estabelecimento de inferências mais eficientes do que a leitura sem interrupções. Os resultados contribuem para um entendimento psicológico das dificuldades de compreensão textual no que concerne ao estabelecimento de inferências, podendo gerar implicações educacionais.

    Full Text Available O diagnóstico laboratorial passou por várias mudanças devido à automatização. Além do aparelhamento, a adoção de um programa de garantia de qualidade (PGQ está resultando em maior precisão nos exames. Para fins de controle em qualidade, o processamento de uma amostra biológica é didaticamente dividido em três fases: pré-analítica, analítica e pós-analítica. Na fase pré-analítica ocorre a maioria dos erros; a divulgação dessas falhas e sua discussão corroboram para a eficiência dos PGQs. No presente estudo, descrevemos as principais variações biológicas encontradas na fase pré-analítica em laboratórios clínicos, por meio de uma revisão sistemática. Fizeram parte dessa revisão 14 artigos. Os parâmetros biológicos descritos na revisão foram, principalmente, glicose, colesterol, triglicérides, enzimas e hormônios. Um erro frequente na punção venosa foi o uso prolongado do torniquete e entre as principais causas de erros observadas foram tempo de armazenamento, tempo de torniquete, técnicas de flebotomia, falta de informações aos pacientes, relação incorreta sangue/anticoagulante, tubos inadequados, amostras contaminadas, medicamentos e alterações interlaboratoriais. Nossos achados são similares aos encontrados em outras pesquisas, mas não encontramos estudos que avaliassem especificamente as alterações na fase pré-analítica decorrentes do uso de medicamentos. Concluímos que os parâmetros biológicos mais avaliados coincidiram com os exames de rotina e uma das formas de evitar às inexatidões laboratoriais é pôr em prática um eficiente PGQ e a produção de trabalhos que explanem o assunto a pacientes e profissionais da saúde.Laboratory diagnosis has undergone several changes due to automation. Both equipment supplying and the introduction of quality assurance programs (QAP have led to higher precision in tests. With the aim to promote quality control, the processing of biological samples

    Full Text Available Foram simuladas quatro estruturas de dados com diferentes padrões de heterogeneidade entre rebanhos e com diferentes graus de conexidade genética. As estruturas simuladas diferiam quanto aos parâmetros heterogêneos entre rebanhos: 1 heterogeneidade para todos os parâmetros; 2 médias genéticas homogêneas e demais parâmetros heterogêneos; 3 heterogeneidade para parâmetros fenotípicos; e 4 rebanhos sem heterogeneidade. Após a predição dos valores genéticos, calculou-se a porcentagem de animais comuns entre dois grupos de classificação para os animais geneticamente superiores: grupo 1 - classificação com base nos valores genéticos verdadeiros e grupo 2 - classificação com base nos valores genéticos preditos. Para dados com heterogeneidade para todos os parâmetros e 0% de conexidade genética, a porcentagem de touros comuns aos dois grupos de classificação foi baixa e houve grandes erros na classificação dos touros geneticamente superiores. Quando os rebanhos possuíam 100% de conexidade genética, esta porcentagem foi superior a 73% e os erros na classificação dos touros foram menores. Para vacas e touros jovens, mesmo para dados com 100% de conexidade genética entre rebanhos, a predição dos valores genéticos foi muito afetada pela presença da heterogeneidade para todos os parâmetros. Para as estruturas sem heterogeneidade para média genética, as porcentagens de animais comuns entre os grupos de classificação foram altas e os erros na classificação dos animais geneticamente superiores foram pequenos, mesmo havendo heterogeneidade para outros parâmetros. Esses resultados sugerem que a heterogeneidade entre rebanhos para médias genéticas teve grande efeito sobre a acurácia da predição dos valores genéticos dos animais. Contudo, quando a heterogeneidade entre os rebanhos ocorreu para outros parâmetros como variância genética, média fenotípica e variância fenotípica, os resultados das avalia

    Full Text Available Introdução: O processo por erro médico costuma ter impacto profundo tanto na vida profissional como na vida pessoal do médico. Entretanto, como a judicialização da medicina é recente, carece de estudos com análise dos fatos a partir da dupla perspectiva da Medicina e do Direito. Objetivo: Analisar os processos da esfera penal do Tribunal de Justiça do Pará. Métodos: Foi realizada uma pesquisa por palavra-chave no site do Tribunal de Justiça do Estado do Pará (TJPA com o termo de pesquisa: “erro médico”. Resultados: Foram encontrados 42 julgados jurisprudenciais. Desses, 24 foram excluídos, pois: 4 eram repetições; 19 eram crimes não cometidos por médicos e 1 por tratar de difamação. Ocorreu uma prescrição e três processos ainda não haviam sido julgados na primeira instância. Dos 14 processos julgados, houve 6 condenações e 8 absolvições. A distribuição por especialidades se deu da seguinte maneira: 8 na ginecologia-obstetrícia (GO; 4 na emergência clínica; 2 na cirurgia geral; 1 em anestesiologia/cirurgia plástica; 1 em oftalmologia; 1 em ortopedia; e 1 em radiologia. Conclusão: Os casos de acusação de supostos erros cometidos por médicos no exercício de suas especialidades ainda são raros no panorama geral do Pará. As especialidades ligadas à cirurgia e às situações de emergência, principalmente GO, foram as principais envolvidas nesse tipo de processo.

MÉTODOS: examinou-se a escrita de 64 sujeitos avaliados pelo Laboratório de Distúrbios de Aprendizagem do Departamento de Neurologia da UNICAMP, diagnosticados com algum problema de aprendizagem: Transtorno do Déficit de Atenção/Hiperatividade (28; Dificuldades de Aprendizagem (13; Distúrbio de Aprendizagem (7; Dislexia (3; Distúrbios Associados (5 e Diagnóstico inconclusivo (9. As idades variaram entre 8;2 e 13;4 anos, média 10;6 anos. Foram incluídos sujeitos alfabetizados, sem rebaixamento intelectual. Os erros foram classificados em 11 categorias e quantificados para análise estatística. RESULTADOS: os erros correspondem àqueles observados em crianças sem queixa de aprendizagem. Os erros por Representações Múltiplas, Omissão de Letras e Oralidade, são respectivamente, os três tipos mais frequentes nos casos de Transtorno do Déficit de Atenção e Hiperatividade, Dificuldades Escolares, Distúrbios Associados e Diagnóstico Desconhecido. No Distúrbio de Aprendizagem a sequência é de Representações Múltiplas, Omissão, Outras Alterações e Surdas-sonoras. Na dislexia observa-se a sequência de Representações Múltiplas, Oralidade, Omissão e Outras Alterações. Existe uma tendência geral de predomínio das alterações ortográficas, embora sem diferença significante em relação aos erros de natureza fonológica. CONCLUSÃO: os erros de natureza ortográfica são os mais frequentes em relação aos de natureza fonológica. Com tendência contrária, os erros visuo-espaciais têm baixa ocorrência em geral, o que mostra que a dificuldade de todos os grupos é fundamentalmente de origem linguística e não perceptual.PURPOSE: to describe the orthographic findings in several types of

    A Olimpíada Brasileira de Astronomia (OBA) contou, em sua quinta edição, com a participação de mais de 60 mil alunos dos ensinos fundamental e médio de praticamente todo o território nacional. Uma das formas de controle que a sua coordenação nacional possui sobre a correção, levada a cabo pelos professores que as aplicaram, é a do envio, por parte destes professores, das 10 melhores provas de cada um dos três níveis nos quais a Olimpíada é realizada. Assim, e dado ao caráter discursivo das provas da Olimpíada, a sua coordenação nacional dispõe de um vasto acervo sobre as concepções, certas ou erradas, dos alunos que dela participaram. Este conjunto de dados jamais fora explorado até o presente trabalho que pretende ser, neste sentido, inaugural. Nas provas dos níveis I e II da V OBA, que abrangem todo o conjunto do ensino fundamental, uma das questões versava sobre a noção que os alunos tinham sobre como os habitantes da Terra situam-se sobre sua superfície. Fizemos um estudo sistemático das respostas a esta questão. Primeiramente, todas as modalidades de erros foram levantadas; em seguida, realizamos uma distribuição por idade tanto do índice de acerto como da ocorrência e da distribuição de cada erro. Como resultado, obtivemos que, em ambos os níveis: 1) as concepções errôneas não se apresentam distribuídas aleatoriamente; 2) há uma concentração no tipo de erro apresentado; 3) há uma tendência de progressivo acerto com relação à idade quando os dados são considerados em termos nacionais; 4) esta tendência nacional é fraca ou mesmo não é verificada em alguns dos estados com maior patamar de acerto.

A investigação, de cunho qualitativo, foi conduzida em uma cidade próxima a Goiânia, capital do Estado de Goiás, e buscou estabelecer relações entre as crenças dos professores e as crenças de alguns de seus alunos dos Ensinos Fundamental e Médio, no segundo semestre de 2003. Os dados foram coletados por meio de questionários, entrevistas, notas de campo, observações e filmagens de aulas e analisados sob duas perspectivas: estudos sobre crenças relacionadas ao processo de ensino e aprendizagem de Horwitz (1985, 1988, 1999, Pajares (1992, Johnson (1994, 1999, Barcelos (1995, 1999, 2004a, 2004b entre outros, e estudos sobre erro e correção de Schulz (1996, Figueiredo (1997, 2005, Lee (2003, entre outros. Os resultados apontam que as experiências que os professores tiveram, quando eram aprendizes de LE, influenciam sua prática cotidiana em sala de aula, bem como as formas como lidam com as questões relativas a erro e correção. Tais crenças são compartilhadas por alguns dos alunos, mas conflitantes com as de outros. Conclui-se, portanto, que é importante fornecer subsídios para que os professores possam conhecer, refletir, discutir e questionar suas crenças, de forma geral, e não apenas sobre erro e correção.This study has as its focus the beliefs which affect both FL teachers and students in regard to error correction.

    Full Text Available Durante el aprendizaje de la Carrera de Odontología los alumnos deben aprobar la materia de Endodoncia, materia de mucha importancia para mantener las piezas dentales en boca y no llegar a una extracción. Lamentablemente, la enseñanza de esta área resulta un poco compleja para el alumno de pregrado ya que se trabaja en un campo muy reducido y relativamente oscuro, lo que dificultad la visualización de los conductos, sumado a la cantidad de pasos que debe realizar para llegar a su objetivo. Dentro de esta enseñanza está la necesidad de impartir conceptos actuales, al igual que técnicas tradicionales vigentes. En la Endodoncia actual se usan tecnologías de tipo mecanizadas que han hecho que el operador pueda realizar procedimientos más rápidos y de manera correcta, pero lastimosamente son sistemas muy costosos que se pueden llegar a fracturar si no se tiene un entrenamiento preclínico previo, el cual logrará una curva de aprendizaje en el uso correcto de los mismos para evitar este desagradable problema. Esta preparación preclínica de acuerdo a la experiencia de las autoras debe tener algunas etapas antes de la realización del procedimiento en el paciente, para disminuir el número de errores durante el proceso clínico, principalmente la indeseable fractura del instrumento de Níquel-Titanio, los cuales son usados actualmente para la conformación del conducto radicular. Por tal motivo se describe en el presente artículo una dinámica de trabajo preclínico por etapas utilizados en la materia de Endodoncia de la Carrera de Odontología de la UCSG para logar este objetivo.

    Full Text Available Principios como el de la indemnización integral del daño ponen en evidencia que la filosofía de la responsabilidad civil es que la víctima de un daño antijurídico obtenga reparación de aquel que es declarado “responsable”. Para alcanzar su objetivo, el régimen de responsabilidad civil cuenta con una serie de fundamentos jurídicos, presunciones, principios y mecanismos orientados a que el responsable repare o indemnice el daño. No obstante, si la miramos desde el punto de vista del responsable, la situación sugiere que la víctima debería también ocuparse del daño que le ha sido causado: pues la víctima tiene la facultad de impedir la aparición de perjuicios derivados del daño y evitar que aquellos que ya tuvieron lugar se hagan más graves. Esto es lo que la doctrina denomina “la obligación de la víctima de moderar el daño”. El análisis de esta obligación demanda un estudio de sus formas de aplicación en los diferentes sistemas de derecho y el de su fundamento jurídico, tanto en la responsabilidad contractual como en la extracontractual; el presente artículo da una primera mirada, general, a este propósito.

    Full Text Available Erros de medicação são constantemente relatados na literatura médico-científica. Há casos clínicos em que a administração inadequada de doses altas de alguns citostáticos tem como consequência a toxicidade grave e a morte do paciente. As não conformidades presentes nas prescrições aos pacientes oncológicos podem ser catastróficas em função da estreita margem terapêutica dos medicamentos antineoplásicos. Prevenir erros de medicação torna-se uma prioridade na melhora do processo farmacoterapêutico em pacientes da oncologia. A multidisciplinaridade é um fator essencial de alerta aos erros de medicação de antineoplásicos e às maneiras de preveni-los Os farmacêuticos e todos os profissionais que constituem uma equipe multidisciplinar de saúde contribuem para garantia do uso seguro dos medicamentos, o que auxilia no aprimoramento de uma assistência qualificada. Para isso, além das atividades já bem estabelecidas, esses profissionais devem (i implantar um sistema de validação farmacêutica bem como (ii estabelecer um sistema de verificação da prescrição médica, o qual consiste em diferentes etapas. O objetivo dessa revisão é relatar a validação da prescrição médica, considerando-se os erros de medicação na quimioterapia e o papel do farmacêutico na prevenção desses erros.

Como resultado, el estudio identificó la escasez de alimento de buena calidad en épocas secas como la principal limitante del productor bovino del municipio. Aprovechando una ventaja presente en la zona, como es la elaboración de panela (proceso a través del cual resultan algunos subproductos, como bagazo y melote, que pueden ser utilizados como alternativa alimenticia para los bovinos en cualquier época del año, se planteó un experimento en el que se elaboraron bloques multinutricionales con base en dichos subproductos. El experimento se adelantó en una finca de un productor y se utilizaron 57 novillos cebús con edades entre los 11 y los 24 meses y pesos entre los 124 y los 463 kilogramos. Los animales se dividieron dos grupos que se mantuvieron en pasturas no manejadas. Al gru¬po experimental se le ofrecieron adicionalmente bloques multinutricionales. Los animales fueron examinados para comprobar su estado fisiológico, con el fin de determinar posibles inconvenientes sanitarios que pudieran afectar el ensayo. Se realizaron pesajes para medir las ganancias de peso en los dos grupos. Los resultados mostraron promedios de ganancias diarias de peso similares a Pr < 5%, donde fueron ligeramente superiores las del grupo alimentado con los bloques multinutricionales (0,848 vs. 0,769 kg animal/día. Los aportes más importantes del experimento fueron, primero, brindar una opción para que el productor pueda alimentar a sus animales en épocas de escasez y evitar que tenga que venderlos a bajos precios. El segundo aporte fue abrir la posibilidad de usar los productos de la elaboración de la panela, que en muchas ocasiones se convierten en desechos que no son usados y que contaminan las fuentes de agua, de una forma económicamente viable.

    evitar a maturação fisiológica de sementes de aveia, tornando essa espécie uma planta daninha potencial para as safras de inverno subsequentes e obrigando a dessecação das plantas emergidas antes da semeadura de culturas comerciais.Black oat is an important winter cover crop in south Brazilian. However, it is a weed problem in cool season grain crops as well as ryegrass. Two trials in a randomized complete block design were conducted at Embrapa Trigo in Passo Fundo, Rio Grande do Sul state. This research aimed to study different oat management methods applied on black oat at anthesis and milk stage to avoid it becoming a weed plant in wheat cropped after soybean. The plot area was 60m². Nine treatments were tested, in both trials: spray herbicide; roll plus herbicide; hay harvest; silage harvest; mowing; grinding, silage; rolling; disking; and grain harvesting. The average total biomass at anthesis was 5,016kg DM ha-1 and at milk stage was 6,050kg DM ha-1. Soybean cropped in the summer season yield 2,080kg ha-1 and it was not affected by black oat treatments. During the second year, the wheat plots sprayed herbicide before planting yielded 2,472kg ha-1 and spike density of 355m-2, however plots without herbicide yielded 836kg ha-1 and had 225 spikes m-2. On black oat milk stage managements the yield average was 1,733kg ha-1 and 334 spikes m-2, on sprayed herbicide plots before planting. In opposite, the plots without herbicide, wheat plants were completely dominated by resurgent black oat plants, due to managements applied during previous winter. Mechanical management methods applied only in black oat development stages allowed seeds germination during winter crops cycle. This problem is avoided spraying herbicide before oat anthesis, because after that any management method tested was unsuccessful to control oat after the following winter crops, so is necessary to spray herbicide before seeding winter cash crops.

    After 13 years in orbit, the Cassini-Huygens Mission to Saturn ended in a science-rich blaze of glory. Cassini returned its final bits of unique science data on September 15, 2017, as it plunged into Saturn's atmosphere satisfying planetary protection requirements. Cassini's Grand Finale covered a period of roughly five months and ended with the first time exploration of the region between the rings and planet.The final close flyby of Titan in late April 2017 propelled Cassini across Saturn’s main rings and into its Grand Finale orbits; 22 orbits that repeatedly dove between Saturn’s innermost rings and upper atmosphere making Cassini the first spacecraft to explore this region. The last orbit turned the spacecraft into the first Saturn upper atmospheric probe.The Grand Finale orbits provided highest resolution observations of both the rings and Saturn, and in-situ sampling of the ring particle composition, Saturn's atmosphere, plasma, and innermost radiation belts. The gravitational field was measured to unprecedented accuracy, providing information on the interior structure of the planet, winds in the deeper atmosphere, and mass of the rings. The magnetic field provided insight into the physical nature of the magnetic dynamo and structure of the internal magnetic field. The ion and neutral mass spectrometer sampled the upper atmosphere for molecules that escape the atmosphere in addition to molecules originating from the rings. The cosmic dust analyzer directly sampled the composition from different parts of the main rings for the first time.

    KASCADE-Grande is the enlargement of the KASCADE extensive air shower detector, realized to expand the cosmic ray studies from the previous 10{sup 14}-10{sup 17} eV primary energy range to 10{sup 18} eV. This is performed by extending the area covered by the KASCADE electromagnetic array from 200x200 to 700x700 m{sup 2} by means of 37 scintillator detector stations of 10 m{sup 2} area each. This new array is named Grande and provides measurements of the all-charged particle component of extensive air showers (N{sub ch}), while the original KASCADE array particularly provides information on the muon content (N{sub {mu}}). Additional dense compact detector set-ups being sensitive to energetic hadrons and muons are used for data consistency checks and calibration purposes. The performance of the Grande array and its integration into the entire experimental complex is discussed. It is demonstrated that the overall observable resolutions are adequate to meet the physical requirements of the measurements, i.e. primary energy spectrum and elemental composition studies in the primary cosmic ray energy range of 10{sup 16}-10{sup 18} eV.

Este artículo analiza el caso de la desnacionalización de la empresa Alpargatas, ocurrida en 1999. Se concluye que la interrupción en el acceso a crédito local e internacional, la recesión doméstica e internacional y la agudización de la competencia en los años finales de la década cumplieron un papel determinante en la extranjerización. Las ventajas comerciales y financieras con que dicha firma contó al principio de la década no alcanzaron para evitar su crisis.

O objetivo desta pesquisa foi testar a ocorrência de vieses de cognição social em um dilema simulado, com base nos procedimentos de (Gifford e Hine, 1997. Após jogarem o software FISH em condições de cooperação e competição, os participantes relataram suas auto e hetero percepções. Foram verificados o viés de falso consenso e o erro fundamental de atribuição, mas os vieses de autosserviço e o ator-observador se mostraram efeitos mais limitados e apenas entre cooperadores. Discutem-se algumas implicações teóricas, metodológicas e práticas dos fenômenos no contexto do consumo sustentável.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A cal sodada desde o início do seu uso sempre apresentou algumas complicações que resultaram em dificuldade na sua aplicabilidade. No entanto, devido as grandes vantagens que oferecia em relação a redução do fluxo de gases frescos, despoluição da sala de cirurgia e umidificação do sistema de inalação e via aérea, fizeram com que continuassem as pesquisas para que pudesse ser melhorada e corrigida de forma que a continuidade da sua utilização fosse assegurada. Atualmente existe o problema da desidratação com elevação da temperatura e da degradação metabólica dos anestésicos halogenados que necessitam de cuidados especiais para evitar a formação de produtos tóxicos. CONTEÚDO: Existe uma reação em cadeia a partir da cal sodada desidratada ou ressecada com baixos volumes percentuais de água. Há aumento da temperatura, maior absorção de anestésico halogenado para o interior do granulo de cal em seguida maior degradação metabólica das moléculas destes agentes e conseqüentemente a produção de substâncias tóxicas como o Composto A pela reação dos hidróxidos com o sevoflurano. Há também formação de monóxido de carbono produzido da mesma forma pela reação entre os halogenados e as bases fortes da cal. O composto A é nefrotóxico e o monóxido de carbono leva a hipóxia e alterações graves da coagulação do sangue. Além dos cuidados para a hidratação da cal sodada é possível usá-la sem conter as bases fortes como os hidróxidos de potássio e de sódio, contendo apenas hidróxido de cálcio para evitar excessivo aumento da temperatura e grande degradação metabólica dos halogenados sem prejudicar a absorção do dióxido de carbono. CONCLUSÕES: Deve-se ter o cuidado em usar a cal sodada mais recente possível e quando ela fica exposta ao meio ambiente (ar seco por muitas horas como por exemplo em um final de semana (mais de 48 horas é recomendável colocar

    The investigation of energy spectrum and mass composition of primary cosmic rays in the energy range 1016-1018 eV and the search for diffuse cosmic gamma rays are of the great interest for understanding mechanisms and nature of high-energy particle sources, the problem of great importance in modern astrophysics. Tunka-Grande scintillator array is a part of the experimental complex TAIGA (Tunka Advanced Instrument for Cosmic Ray and Gamma Astronomy) which is located in the Tunka Valley, about 50 km from Lake Baikal. The purpose of this array is the study of diffuse gamma rays and cosmic rays of ultra-high energies by detecting extensive air showers. We describe the design, specifications of the read-out, data acquisition (DAQ) and control systems of the array.

    2017-12-01

    We present a field theoretical model unifying grand unified theory (GUT) and brane world scenario. As a concrete example, we consider S U (5 ) GUT in 4 +1 dimensions where our 3 +1 dimensional spacetime spontaneously arises on five domain walls. A field-dependent gauge kinetic term is used to localize massless non-Abelian gauge fields on the domain walls and to assure the charge universality of matter fields. We find the domain walls with the symmetry breaking S U (5 )→S U (3 )×S U (2 )×U (1 ) as a global minimum and all the undesirable moduli are stabilized with the mass scale of MGUT. Profiles of massless standard model particles are determined as a consequence of wall dynamics. The proton decay can be exponentially suppressed.

    The last decade has shown us that the observational properties of neutron stars are remarkably diverse. From magnetars to rotating radio transients, from radio pulsars to isolated neutron stars, from central compact objects to millisecond pulsars, observational manifestations of neutron stars are surprisingly varied, with most properties totally unpredicted. The challenge is to establish an overarching physical theory of neutron stars and their birth properties that can explain this great diversity. Here I survey the disparate neutron stars classes, describe their properties, and highlight results made possible by the Chandra X-Ray Observatory, in celebration of its 10th anniversary. Finally, I describe the current status of efforts at physical "grand unification" of this wealth of observational phenomena, and comment on possibilities for Chandra's next decade in this field.

Estratégias podem ser utilizadas e devem ser divulgadas para minimizar a ocorrência de erros. Este estudo foi planejado tendo os seguintes objetivos: identificar e analisar em periódicos das áreas de enfermagem, farmácia e hospitalar, publicações com temas ligados a administração de medicamentos e verificar a identificação no leito e no antebraço de pacientes internados em uma instituição hospitalar . Para alcançar o primeiro objetivo realizou-se uma revisão da literatura sobre a temática em estudo, em três periódicos de maior circulação nacional das áreas descritas, no período de 1987 a 1997. Os artigos identificados foram agrupados em 5 tipos: assistência de enfermagem, ensino, medicamentos, pesquisa e técnica. Identificou-se 19 artigos sobre a temática estudada, sendo 42,1% destes voltados para os aspectos técnicos da administração de medicamentos. Para atingir o segundo objetivo realizou-se uma investigação de um dia, escolhido casualmente, verificando-se os 360 leitos da instituição quanto a identificação nos mesmos e nos pacientes. Destes, 74,7% estavam ocupados e 75,8% devidamente identificados. Observou-se que 23,8% dos pacientes possuíam pulseira de identificação colocada, na maioria dos pacientes, no dia anterior à cirurgia e não no momento da internação. Os resultados evidenciaram a pouca importância tanto do estudo desta temática, quanto na identificação do paciente e do leito por parte da instituição.

    Full Text Available Ao observar as condições de trabalho médico no Brasil, nota-se uma inadequação entre o sistema de saúde, modelo de medicina e demandas sociais. Os médicos exercem suas funções num sistema de saúde precário, que não dispõe de equipamentos, leitos, medicamentos e profissionais suficientes para o atendimento ao paciente, ocasionando filas imensas e stress no ambiente de trabalho. A racionalidade orientadora da medicina ocasiona mudanças do ponto de vista da evolução científico-tecnológica e demanda tanto profissionais especializados quanto equipamentos sofisticados. O tratamento médico perde o seu caráter humano de cuidado ao enfermo para adquirir um caráter técnico, em que o procedimento em si é valorizado, em detrimento do resultado final. O médico especializado não é mais o profissional da saúde do paciente e, sim aquele que lhe prescreve condutas para “uma determinada enfermidade”. Palavras-chave: Erro médico. Processo trabalho. Situação de trabalho. Especialização. Qualificação. By observing medical work conditions in Brazil we notice the inadequacy of the health system, medicine patterns and social demand. Physicians perform their functions in a precarious health system, not having at one’s disposal enough equipment, sickbeds, medicines and professionals to attend patients, hence causing long lines and stress in the working environment. The rationality that orients medicine causes changes from the point of view of the technological and scientific evolution, and demands both specialized professionals and sophisticated equipments. The medical treatment loses its human character of caring for the sick to acquire a technical one, where the procedure itself is valued to the detriment of the final result. The specialized physician is no more the ‘health’ professional of the patient, but the one who prescribes conduct to ‘a certain illness’. Keywords: Medical errors. Work process. Working

MÉTODOS: Estudo retrospectivo de 227 pacientes adultos com diagnóstico confirmado de PCM (forma crônica entre 1980 e 2005. RESULTADOS: Dos 227 casos, 36 (15,8% haviam sido tratados anteriormente para TB. Porém, apenas 18 (7,9% apresentaram baciloscopia positiva. Os outros 18 (7,9% nunca tiveram o diagnóstico confirmado pela baciloscopia nem responderam ao tratamento específico para TB. CONCLUSÃO: Apesar de a associação entre PCM e TB existir e estar documentada na literatura, o erro diagnóstico é bastante comum, haja vista a sobreposição e similaridade das apresentações clínicas e radiológicas dessas duas doenças, havendo, portanto, a necessidade do diagnóstico bacteriológico antes de se iniciar o tratamento específico.OBJECTIVE: To evaluate the frequency of the real association between paracoccidioidomycosis (PCM and tuberculosis (TB as well as the rate of previous TB misdiagnosis in individuals with PCM among the patients treated in the Pulmonology Division of the State University of Campinas Hospital das Clínicas, Campinas, Brazil. METHODS: A retrospective study of 227 adult patients with PCM (chronic form treated between 1980 and 2005. RESULTS: Of the 227 patients studied, 36 (15.8% had been previously treated for TB. However, only 18 (7.9% presented positive sputum smear microscopy results. The remaining 18 (7.9% neither presented positive sputum smear microscopy nor showed improvement after receiving specific anti-TB treatment. CONCLUSION: Although the existence of an association between PCM and TB has been documented in the literature, misdiagnosis is common due to the superimposition of and the similarity

    Full Text Available INTRODUÇÃO: A amplitude de movimento articular (ADM é um importante componente avaliado durante o exame físico; porém, para que essa mensuração possa ser utilizada, é necessário que ela seja confiável e que suas propriedades de medida sejam conhecidas. OBJETIVOS: Verificar a confiabilidade inter e intraexaminadores das medidas realizadas pelo goniômetro e inclinômetro na avaliação da ADM de flexão e extensão de joelho e cotovelo, e determinar o erro padrão da medição (EPM dos instrumentos em questão. MÉTODOS: Foi avaliada ADM de flexão e extensão de cotovelo e joelho, bilateralmente, de uma amostra de indivíduos jovens saudáveis do gênero masculino, com faixa etária entre 18 e 30 anos, utilizando um inclinômetro digital e um goniômetro universal. RESULTADOS: A confiabilidade interexaminador variou de pequena a muito alta para os dois instrumentos, apresentando CCI de 0,24 a 0,96 para as medidas feitas com o goniômetro, e de 0,02 a 0,98 para o inclinômetro. O único movimento que obteve confiabilidade muito alta para ambos os aparelhos e examinadores foi a flexão de joelho. O EPM determinado por meio da goniometria e inclinometria variou entre 0,21 e 12,75 graus. CONCLUSÃO: O inclinômetro digital apresenta melhores índices de confiabilidade que o goniômetro para as medidas de ADM. Apenas quatro medidas obtiveram CCI alto e EPM abaixo de dois graus, e, assim, foram consideradas apropriadas para serem utilizadas clinicamente, todas essas realizadas com o inclinômetro.

    Full Text Available O mapa de produtividade é considerado, por muitos autores, o início da Agricultura de Precisão. A tecnologia para a coleta automatizada de pontos de produtividade proporciona intensa densidade amostral com a inevitável coleta de pontos que contêm erros na medição da produtividade e que podem interferir na análise e na tomada de decisão baseada no mapa. Este trabalho tem por objetivo desenvolver uma metodologia para identificar e caracterizar erros em mapas de produtividade, e aplicá-la para seis diferentes monitores de produtividade comerciais. Nos dados analisados foram encontrados erros de posicionamento, pontos com produtividade nula ou extrema, ausência de medida de umidade dos grãos, largura de plataforma incorretamente registrada pelo operador, dados inconsistentes durante o intervalo referente ao tempo de enchimento e de esvaziamento da colhedora nos inícios e finais de passadas e, também, dados discrepantes. Todos esses erros foram devidamente caracterizados e forneceram bases para a formulação de uma rotina de filtragem de dados brutos.For many researchers, yield mapping is the start of Precision Farming. Yield monitors measure the yield and collect data in a high frequency allowing the collection of erroneous data that may interfere in the decision-making based on yield maps. The objective of this work was to develop a methodology to identify and characterize errors in yield maps and apply the methodology to a set of data obtained from six different commercial yield monitors. With the analyzed data, errors were found and characterized as positioning errors, null or extremely high yield points with no measurements of grain moisture, swath width errors due to wrong interpretation of the effective cutting width by the operator, time errors and disagreeable data. All these errors were characterized and furnished the basis for the formulation of a routine for filtering the new yield data.

Foram quantificados e classificados erros produzidos pelos sujeitos, visando descrever aqueles de maior freqüência, verificando se há diferença entre a ocorrência dos mesmos. Pretendeu-se caracterizar um perfil ortográfico indicativo das dificuldades gerais mais comumente encontradas nesta população. MÉTODOS: foi examinada a escrita de 69 sujeitos avaliados pelo Laboratório de Distúrbios de Aprendizagem do Departamento de Neurologia da UNICAMP e diagnosticados como apresentando algum tipo de problema de aprendizagem. As idades variaram entre oito anos e dois meses e treze anos e quatro meses, com uma média de dez anos e seis meses. Foram incluídos somente sujeitos em nível alfabético de escrita, sem qualquer tipo de rebaixamento intelectual. Os erros encontrados foram classificados em onze categorias e quantificados para fins de análise estatística. RESULTADOS: dez grupos foram diagnosticados, sendo o Transtorno do Déficit de Atenção o mais numeroso, seguido por Dificuldades Escolares e Transtornos Associados. A maior parte dos sujeitos cursava a terceira série do ensino fundamental. O tipo de erro mais recorrente foi "Representações Múltiplas", seguido de "Omissões" e "Apoio na Oralidade". Observou-se correlação significativa principalmente entre "Omissões" e "Outras Alterações". CONCLUSÃO: a maior dificuldade encontrada está centrada nas "Representações Múltiplas", revelando dificuldades principalmente no nível ortográfico. Os erros por omissão de letras decorrem de falhas no processo de análise fonológica e de correspondência fonema-grafema. A baixa ocorrência de erros por "Inversão" e por "Letras Parecidas", indica ausência de dificuldades de natureza visual-espacial.PURPOSES: to analyze orthographic abilities of children diagnosed with some kind of learning problems.

    Full Text Available A verificação anual da acuidade visual (AV em crianças e adultos deve ser recomendada como programa preventivo devido ao alto índice de distúrbios visuais existentes. As últimas estimativas da Organização Mundial da Saúde (OMS indicam que há 161 milhões de pessoas com alguma deficiência visual em todo o mundo, com um aumento anual de 1 a 2 milhões de indivíduos afetados. Programas de assistência oftalmológica sanitária são necessários como forma de atendimento básico preventivo-educativo, para promover a saúde ocular e encaminhar, precocemente, a população para tratamento adequado. A acuidade visual é o indicador mais imediato da função visual, sendo um exame rápido, simples, de fácil realização e de baixo custo. O método de medida da AV, a partir das tabelas de Snellen e de Jaeger, é preferencialmente usado como triagem em campanhas de saúde visual. A liga de oftalmologia da Universidade Severino Sombra realizou um estudo sobre os erros de refração de populares da região Sul Fluminense, através de feiras de saúde realizadas desde o ano de 2007 até 2011. Participaram desta pesquisa 125 pessoas, sendo o único pré-requisito para esta seleção o fato do indivíduo ter participado em uma das feiras de saúde. O objetivo deste trabalho foi avaliar o déficit visual desta amostra da população, e relacionar a incidência de alterações na AV com o uso correto/incorreto de correção refracional.O uso incorreto é caraterizado através do uso da correção sem necessidade ou com o índice de refração inadequado. Os resultados demonstraram que 32,8% das pessoas avaliadas tiveram alterações no índice de refração, e 35,2% faziam uso de correção refracional. Isto indica que 2,4% da população avaliada utiliza AV inadequadamente. Estes resultados enaltecem a importância do acompanhamento oftalmológico, para diagnóstico da necessidade de correção visual ou suspensão do uso desta sem necessidade.

    Several lines of evidence have stressed that melt-rock reactions acting at the oceanic mantle-crust boundary play an important role in the chemical evolution of MORBs and the formation of the primitive (olivine-rich) lower oceanic crust. To address this issue, we performed detailed structural analyses and in-situ mineral geochemistry on the Erro-Tobbio (ET) ultramafic unit (Ligurian Alps, Italy), where impregnated mantle peridotites are primarily associated to a hectometre-size mafic body composed of troctolite to plagioclase-bearing wehrlite. The troctolitic body exhibits high complexity, with a host troctolite (Troctolite A) crosscut by troctolitic decametre-size pseudo-tabular bodies (Troctolite B). These different generations of troctolites show distinct modal compositions and textures. The host troctolite A displays a dominant millimetre-size corroded granular texture of olivine associated with dunite pods and a layering defined by poikilitic plagioclase enrichment. The contact between the mafic body and the host mantle peridotites is irregular, and defined by troctolite to wehrlite apophyses. The troctolite A shows microstructures and Crystallographic Preferred Orientation (CPO) indicative of a formation after impregnation of a mantle dunite by an olivine-undersaturated melt. This impregnation leads to olivine dissolution, associated with poikilitic plagioclase and clinopyroxene crystallization. This is indicated by a progressive randoming of the Axial-[100] CPO with olivine disaggregation and increasing melt input in the troctolite. The crosscutting troctolite B exhibits significant olivine textural variation, from fine-grained granular to deformed coarse-grained skeletal olivine. Olivine in the troctolite B shows CPO indicative of crystallization after magmatic flow, intrusive into the host troctolite A. Both troctolite types display large major and trace element variations in minerals, e.g. variation of Anorthite content (An = 54-67) in plagioclase at

O método utilizado foi o estudo transversal que avaliou 2 620 doses de medicamentos dispensados entre agosto e setembro de 2006, em um serviço de farmácia de um hospital pediátrico do Espírito Santo. Os erros de dispensação foram definidos como qualquer desvio entre o dispensado e o prescrito na receita médica. Os erros foram categorizados em conteúdo, rotulagem e documentação. A taxa de erro de dispensação foi calculada dividindo o número de erros total/total de doses dispensadas. Os resultados mostraram que, dos 300 erros identificados, 262 (87,3% foram de conteúdo. Nas categorias erros de rotulagem a taxa foi de 33 (11% e 5 (1,7% na de erros de documentação. Concluiu-se que a taxa total de erros de dispensação foi elevada quando comparada à descrita em estudos internacionais. A categoria de erro mais freqüente foi a de erro de conteúdo.

    When our knowledge of a field accumulates to a certain level, we are bound to see the rise of one or more great scientists. They will make a series of grand discoveries/breakthroughs and push the discipline into an 'age of grand discoveries'. Mathematics, geography, physics and chemistry have all experienced their ages of grand discoveries; and in life sciences, the age of grand discoveries has appeared countless times since the 16th century. Thanks to the ever-changing development of molecular biology over the past 50 years, contemporary life science is once again approaching its breaking point and the trigger for this is most likely to be 'lifeomics'. At the end of the 20th century, genomics wrote out the 'script of life'; proteomics decoded the script; and RNAomics, glycomics and metabolomics came into bloom. These 'omics', with their unique epistemology and methodology, quickly became the thrust of life sciences, pushing the discipline to new high. Lifeomics, which encompasses all omics, has taken shape and is now signalling the dawn of a new era, the age of grand discoveries.

    Full Text Available O objetivo deste artigo é verificar o comportamento das cartas de média e desvio padrão de Shewhart em relação à probabilidade do erro do tipo I quando da violação da suposição de normalidade. Foi realizada a simulação de uma série de 500.000 amostras (subgrupos de tamanho n = 3, 5, 7, 10, 15, 20 e 25. As amostras foram simuladas a partir das distribuições normal, t de Student, exponencial, qui-quadrado, gamma e Weibull. Verificou-se em dados não normais o aumento na probabilidade de erro do tipo I na carta de médias em todas as distribuições simuladas. O mínimo tamanho da amostra necessário está relacionado ao grau de assimetria da distribuição dos dados, sendo que, em alguns casos, nem mesmo n = 25 apresentou resultados satisfatórios. No gráfico S, o aumento da probabilidade de erro do tipo I é significativamente superior em quase todas as distribuições simuladas e seu comportamento é influenciado não só pelo tipo de distribuição, mas também pelo tamanho da amostra.The purpose of this article was to examine the performance of Shewhart average and standard deviation control charts in relation to the probability of type I error at the occurrence of normality assumption violation. A simulation of a series of 500,000 samples (subgroups of sizes n=3, 5, 7, 10, 15, 20 and 25 was performed. The samples were simulated from the following distributions: Normal, Binomial, Poisson, Exponential, Chi-square, Gamma and Weibull. It was possible to find that, in non-normal data, there was an increase in the probability of type I error on the average chart of all simulated distributions. The minimum sample size required is related to the degree of asymmetry of the data distribution and, in some cases, not even n=25 presented satisfactory results. In the S chart, the increased probability of type I error is significantly higher for almost all distributions simulated and its performance is influenced not only by the type of

    The status and capabilities of the KASCADE-Grande extensive air shower experiment are presented. The installation is located at Forschungszentrum Karlsruhe and comprises a large collecting area (0.5 km{sup 2}) electromagnetic array (Grande) operated jointly with the existing KASCADE detectors. KASCADE-Grande will cover the primary energy range 10{sup 16} eV < E{sub 0} < 10{sup 18} eV overlapping with KASCADE around 1016 eV, thus providing continuous information on the primary energy and mass of cosmic rays from 3 {center_dot} 1014 eV up to 10{sup 18} eV. The major goal of the measurements is the unambiguous observation of the 'iron knee' expected in the cosmic ray spectrum at E{sub k}{sup Fe} {approx} 10{sup 17} eV.

  2. Research Furthers Conservation of Grand Canyon Sandbars

    2007-01-01

    Grand Canyon National Park lies approximately 25 km (15 mi) down-river from Glen Canyon Dam, which was built on the Colorado River just south of the Arizona-Utah border in Glen Canyon National Recreation Area. Before the dam began to regulate the Colorado River in 1963, the river carried such large quantities of red sediment, for which the Southwest is famous, that the Spanish named the river the Rio Colorado, or 'red river'. Today, the Colorado River usually runs clear below Glen Canyon Dam because the dam nearly eliminates the main-channel sand supply. The daily and seasonal flows of the river were also altered by the dam. These changes have disrupted the sedimentary processes that create and maintain Grand Canyon sandbars. Throughout Grand Canyon, sandbars create habitat for native plants and animals, supply camping beaches for river runners and hikers, and provide sediment needed to protect archaeological resources from weathering and erosion. Maintenance of sandbars in the Colorado River ecosystem, the river corridor that stretches from the dam to the western boundary of Grand Canyon National Park, is a goal of the Glen Canyon Dam Adaptive Management Program. The program is a federally authorized initiative to ensure that the mandates of the Grand Canyon Protection Act of 1992 are met through advances in information and resource management. The U.S. Geological Survey's Grand Canyon Monitoring and Research Center has responsibility for scientific monitoring and research efforts for the program. Extensive research and monitoring during the past decade have resulted in the identification of possible alternatives for operating Glen Canyon Dam that hold new potential for the conservation of sand resources.

    The effective Higgs theories at the TeV scale in supersymmetric SU(5) grand unification models are systematically derived. Restricted to extensions on 5{sub H} containing the Higgs sector we show that only two types of real (vector-like) models and one type of chiral model are found to be consistent with perturbative grand unification. While the chiral model has been excluded by the LHC data, the fate of perturbative unification will be uniquely determined by the two classes of vector-like models. (orig.)

    Full Text Available Der Grand Prix Eurovision ist seit Jahrzehnten eine der bekanntesten Unterhaltungssendungen im europäischen Raum. Dennoch erregte es Verwunderung, wenn der Schreibende Bekannten darüber berichtete, daß dies ein Forschungsgegenstand sei. Wurde von Interviews mit Grand Prix-Fans erzählt, so fielen schnell Aussagen wie: „Wie kann man sich nur für so etwas Abseitiges und Triviales wie den Grand Prix interessieren“. Dennoch bin ich der Meinung, daß Fankulturen für die entstehende Mediengesellschaft ein nicht unwichtiges Forschungsthema darstellen. Zwar geht es nicht um eine medienpädagogische Fragestellung im engeren Sinne; die Fans des Grand Prix Eurovision sind dem Jugendalter längst entwachsen. Dennoch handelt es sich bei Fangemeinschaften um Phänomene, die im Rahmen von Jugend- und Kinderkulturen von besonderer Relevanz sind. So meint Winter (1997, daß jugendliche Fanwelten eine bedeutende Rolle als Kristallisationspunkte kultureller Differenzierung spielen: ,Die Zugehörigkeit zu einer Fan weit ist Teil der jugendlichen Lebensbewältigung in der Postmoderne, denn in der Gemeinschaft der Fans können Jugendliche emotionale Allianzen eingehen, außeralltäglichen Beschäftigungen nachgehen, expressive Identitätsmuster gemeinschaftlich realisieren und sich mit ihrer Lebenssituation als Heranwachsende auseinandersetzen“ (Winter 1997, S. 51f..

  1. Creationism in the Grand Canyon, Texas Textbooks

    2004-01-01

    AGU President Bob Dickinson, together with presidents of six other scientific societies, have written to Joseph Alston, Superintendent of Grand Canyon National Park, pointing out that a creationist book, The Grand Canyon: A Different View, is being sold in bookstores within the borders of the park as a scientific explanation about Grand Canyon geologic history. President Dickinson's 16 December letter urges that Alston clearly separate The Grand Canyon: A Different View from books and materials that discuss the legitimate scientific understanding of the origin of the Grand Canyon. The letter warns the Park Service against giving the impression that it approves of the anti-science movement known as young-Earth creationism, or that it endorses the advancement of religious tenets disguised as science. The text of the letter is on AGU's Web site http://www.agu.org/sci_soc/policy/sci_pol.html. Also, this fall, AGU sent an alert to Texas members about efforts by intelligent design creationists aimed at weakening the teaching of biological evolution in textbooks used in Texas schools. The alert pointed scientists to a letter, drafted by AGU, together with the American Institute of Physics, the American Physical Society, the Optical Society of America, and the American Astronomical Society, that urged the Texas State Board of Education to adopt textbooks that presented only accepted, peer-reviewed science and pedagogical expertise. Over 550 scientists in Texas added their names to the letter (http://www.agu.org/sci_soc/policy/texas_textbooks.pdf ), sent to the Board of Education on 1 November prior to their vote to adopt a slate of new science textbooks. The Board voted 11-5 in favor of keeping the textbooks free of changes advocated by groups supporting intelligent design creationism.

    Full Text Available A cor do solo é uma característica facilmente determinada através da comparação visual com a carta de Munsell e está relacionada com a presença de óxidos de ferro e matéria orgânica no solo. A obtenção da cor por instrumentos via sensoriamento remoto, como colorímetros, resulta em maior precisão por apresentar condições controladas e não subjetivas. Os objetivos deste trabalho foram comparar a cor de diferentes solos do Rio Grande do Sul determinadas pela carta de Munsell e por colorimetria e correlacioná-las com os atributos do solo. A precisão dos observadores na determinação da cor através da carta de Munsell para uma mesma amostra apresentou menor variabilidade para o componente matiz e maior para o croma. Os coeficientes de correlação mostraram que há coerência entre as medidas de cor realizadas por diferentes observadores e as medidas pelo colorímetro, o qual mostrou ser eficiente na quantificação da cor, eliminando possíveis erros psicofísicos atribuídos ao método visual. Os atributos dos solos analisados apresentaram boas correlações com os componentes da cor obtidos por colorimetria, mostrando ser esta uma técnica eficiente e promissora para obter informações do solo de maneira simples e de baixo custo.

    The KASCADE-Grande experiment measures extensive air showers induced by cosmic rays in the energy range between 0.5 PeV and 1 EeV - the so-called knee region. Principal task of the experiment is to measure with high accuracy the energy and composition of primary cosmic rays to shed light on the nature of the knee. The data of the former KASCADE experiment have been used in a composition analysis showing the knee at 3-5 PeV to be caused by a steepening in the light-element spectra. In the following, an update on these analyses will be given. In addition, the status of the experimental extension - the Grande array - together with first results will be briefly discussed.

    This review identifies an agenda for global health by highlighting the current 'grand challenges' related to governance. Literature from the disciplines of health policy and medicine, conference presentations and documents, and materials from international agencies (such as the World Health Organization). The present approach to global health governance has proven to be inadequate and major changes are necessary. The source of problems behind the current global health governance challenges have not always been agreed upon, but this paper attempts to highlight the recurrent themes and topics of consensus that have emerged in recent years. A solution to the 'grand challenges' in global health governance is urgently needed and serves as an area for developing research.

    The Rio Grande Gorge is a 115 km long river canyon located in Southern Colorado (15 km) and Northern New Mexico (100 km). The majority of the canyon is under the administration of the Bureau of Land Management {BLM), and 77 km of the canyon south of the Colorado/New Mexico border are designated Wild River under the National Wild and Scenic Rivers Act of 1968. Visits I have made to the Rio Grande Gorge over the past 15 .years disclosed some raptor utilization. As the Snake River Birds of Prey Natural Area gained publicity, its similarity to the Rio Grande Gorge became obvious, and I was intrigued by the possibility of a high raptor nesting density in the Gorge. A survey in 1979 of 20 km of the northern end of the canyon revealed a moderately high density of red-tailed hawks and prairie falcons. With the encouragement of that partial survey, and a need to assess the impact of river-running on nesting birds of prey, I made a more comprehensive survey in 1980. The results of my surveys, along with those of a 1978 helicopter survey by the BLM, are presented in this report, as well as general characterization of the area, winter use by raptors, and an assessment of factors influencing the raptor population.

    An overview of the exploration and on-going activities by the petroleum industry on the Grand Banks of Newfoundland was presented. The two offshore oil developments underway are Hibernia and Terra Nova, both located in the Jeanne d`Arc Basin. Current production from Hibernia is 68,000 bopd, expected to rise to 130,000 bopd in 1999. The Terra Nova Field is still under development. Total recoverable reserves from the 17 discoveries made in the Jeanne d`Arc Basin are estimated at 1.6 billion barrels of oil and 4 trillion cubic feet of gas. Industry participants in the area include Amoco, Petro-Canada, Mobil, Chevron, Husky and Norsk Hydro. Petro-Canada believes the Grand Banks represent one of the best opportunities for oil anywhere in the world. There are currently 21 exploration licenses held on the Grand Banks. Major attractions of the area include the large reserve potential, the relatively low finding costs, the size of the pools being discovered, improvements in offshore technology that have substantially lowered development costs, and a profit-sensitive generic royalty regime that ensures reasonable rates of return for investors. figs.

    This collection addresses two different audiences: 1) historians and philosophers of the life sciences reflecting on collaborations across disciplines, especially as regards defining and addressing Grand Challenges; 2) researchers and other stakeholders involved in cross-disciplinary collaborations aimed at tackling Grand Challenges in the life and medical sciences. The essays collected here offer ideas and resources both for the study and for the practice of goal-driven cross-disciplinary research in the life and medical sciences. We organise this introduction in three sections. The first section provides some background and context. The second motivates our take on this topic and then outlines the central ideas of each paper. The third section highlights the specificity and significance of this approach by considering: a) how this collection departs from existing literature on inter- and trans-disciplinarity, b) what is characteristic about this approach, and c) what role this suggests for the history and philosophy of the life sciences in addressing Grand Challenges.

    The timing of carving of Grand Canyon has been debated for over 100 years with competing endmember hypotheses advocating for either a 70 Ma (;old;) or distribution of radiogenic 4He (from the 238U, 235U and 232Th decay series) within an individual apatite crystal and thus are highly sensitive to the thermal history corresponding to landscape evolution. However, there are several complicating factors that make interpreting such data challenging in geologic scenarios involving reheating. Here, we analyze new data that provide measures of the cooling of basement rocks at the base of westernmost Grand Canyon, and use these data as a testbed for exploring the resolving power and limitations of 4He/3He data in general. We explore a range of thermal histories and find that these data are most consistent with a ;young; Grand Canyon. A problem with the recovered thermal history, however, is that burial temperatures are under predicted based on sedimentological evidence. A solution to this problem is to increase the resistance of alpha recoil damage to annealing, thus modifying He diffusion kinetics, allowing for higher temperatures throughout the thermal history. This limitation in quantifying radiation damage (and hence crystal retentivity) introduces non-uniqueness to interpreting time-temperature paths in rocks that resided in the apatite helium partial retention zone for long durations. Another source of non-uniqueness, is due to unknown U and Th distributions within crystals. We show that for highly zoned with a decrease in effective U of 20 ppm over the outer 80% of the radius of the crystal, the 4He/3He data could be consistent with an ;old; canyon model. To reduce this non-uniqueness, we obtain U and Th zonation information for separate crystals from the same rock sample through LA-ICP-MS analysis. The observed U and Th distributions are relatively uniform and not strongly zoned, thus supporting a ;young; canyon model interpretation of the 4He/3He data. Furthermore

    Full Text Available O trabalho foi realizado na Floresta Ombrófila Mista, de grande diversidade tipológica, em São Francisco de Paula, Rio Grande do Sul. O objetivo foi estimar a serapilheira acumulada, coletada com diferentes tamanhos de molduras e determinar a intensidade amostral em cada estação sazonal. Foram obtidas 15 amostras aleatórias por hectare para cada moldura em cada estação sazonal. A serapilheira foi separada nos estratos folhas, cascas, galhos e miscelâneas, foi secada e pesada e os dados foram expressos em t ha-1. Procedeu-se uma análise de variância conjunta com as fontes de variação "moldura, estação, interação e erro". Foi estimada a média, a variância e o coeficiente de variação e foi realizado o teste de homogeneidade das variâncias entre as estações e entre as molduras. Admitindo-se um erro de amostragem máximo de 10, 15, 20 e 25% da média estimada, calculou-se a intensidade de amostragem, por hectare, para população infinita. A interação entre moldura e estação não foi significativa para a serapilheira e para os estratos e nem houve diferenças significativas entre as molduras. As variâncias da serapilheira foram homogêneas entre as molduras nas quatro estações e foram heterogêneas entre as estações nas quatro molduras. É preferido usar a moldura muito pequena (0,25m², com 27 unidades de amostra no inverno, 25 na primavera, 33 no outono e 15 no verão para uma precisão de 15% de diferença entre as médias.The present research was accomplished in the Forest Mixed Ombrófila of São Francisco de Paula - FLONA, being this representative of great diversity in the State of Rio Grande do Sul.

    A snowfall in the American West provides contrast to the landscape's muted earth tones and indicates changes in topography and elevation across (clockwise from top left) Nevada, Utah, Colorado, New Mexico, Arizona, and California. In Utah, the southern ranges of the Wasatch Mountains are covered in snow, and the Colorado River etches a dark ribbon across the red rock of the Colorado Plateau. In the center of the image is the reservoir created by the Glen Canyon Dam. To the east are the gray-colored slopes of Navaho Mountain, and to the southeast, dusted with snow is the region called Black Mesa. Southwest of Glen Canyon, the Colorado enters the Grand Canyon, which cuts westward through Arizona. At a deep bend in the river, the higher elevations of the Keibab Plateau have held onto snow. At the end of the Grand Canyon lies another large reservoir, Lake Mead, which is formed by the Hoover Dam. Credit: Jacques Descloitres, MODIS Land Rapid Response Team, NASA/GSFC

    The KASCADE-Grande experiment, located at Forschungszentrum Karlsruhe (Germany), is a multi component extensive air-shower experiment dedicated to the study of cosmic-rays and their interactions at primary energies 10{sup 14}-10{sup 18}eV. The main goal of the experiment is the detection of the 'iron-knee' in the energy spectrum at around 10{sup 17} eV, which is expected following the KASCADE and EAS-TOP observations where the positions of the knees of individual mass groups suggest a rigidity dependence. The experiment consists of the former KASCADE (detecting the electromagnetic, the muonic at different energy thresholds and the hadronic components) and Grande, which is an array of plastic scintillators providing a large acceptance area (0.5 km{sup 2}). In addition the experiment measures in coincidence with the LOPES radio antennas. The experimental set-up, the EAS reconstruction accuracies and first studies, based on 1 year of data taking, are presented.

  6. Aspects Of Grand Unified And String Phenomenology

    Walker, J W

    2005-01-01

    Explored in this report is the essential interconnectedness of Grand Unified and String Theoretic Phenomenology. In order to extract a modeled connection to low-energy physics from the context of superstring theory, it is presently necessary to input some preferred region of parameter space in which to search. This need may be well filled by a parallel study of Grand Unification, which is by contrast in immediate proximity to a wealth of experimental data. The favored GUT so isolated may then reasonably transfer this phenomenological correlation to a string embedding, receiving back by way of trade a greater sense of primary motivation, and potentially enhanced predictability for parameters taken as input in a particle physics context. The Flipped SU(5) GUT will be our preferred framework in which to operate and first receives an extended study in a non-string derived setting. Of particularly timely interest are predictions for super-particle mass ranges and the interrelated question of proton decay lifetime....

  7. Elastoplasticidad anisotropa de metales en grandes deformaciones

    Caminero Torija, Miguel Angel

    El objetivo de este trabajo es el desarrollo de modelos y algoritmos numericos que simulen el comportamiento del material bajo estas condiciones en el contexto de programas de elementos finitos, dando como resultado predicciones mas precisas de los procesos de conformado y deformacion plastica en general. Para lograr este objetivo se han desarrollado diversas tareas destinadas a mejorar las predicciones en tres aspectos fundamentales. El primer aspecto consiste en la mejora de la descripcion del endurecimiento cinematico anisotropo en pequenas deformaciones, lo cual se ha realizado a traves de modelos y algoritmos implicitos de superficies multiples. Ha sido estudiada la consistencia de este tipo de modelos tanto si estan basados en una regla implicita similar a la de Mroz o en la regla de Prager. Ademas se han simulado los ensayos de Lamba y Sidebottom, obteniendo, en contra de la creencia general, muy buenas predicciones con la regla de Prager. Dichos modelos podrian ser extendidos de forma relativamente facil para considerar grandes deformaciones a traves de procedimientos en deformaciones logaritmicas, similares a los desarrollados en esta tesis y detallados a continuacion. El segundo aspecto consiste en la descripcion de la anisotropia elastoplastica inicial. Esto se ha conseguido mediante el desarrollo de modelos y algoritmos para plasticidad anisotropa en grandes deformaciones, bien ignorando la posible anisotropia elastica, bien considerandola simultaneamente con la anisotropia plastica. Para ello ha sido necesario desarrollar primero un nuevo algoritmo de elastoplasticidad anisotropa en pequenas deformaciones consistentemente linealizado y sin despreciar ningun termino, de tal forma que se conserve la convergencia cuadratica de los metodos de Newton. Este algoritmo en pequenas deformaciones ha servido para realizar la correccion plastica de dos algoritmos en grandes deformaciones. El primero de estos algoritmos es una variacion del clasico algoritmo de

MÉTODOS: o desempenho de um grupo de 15 disléxicos foi comparado ao de dois grupos controles, pareados por idade e por nível de leitura. RESULTADOS: os grupos dislexia e controle por leitura não diferiram quanto ao número de acertos, mas ambos acertaram menos que o grupo controle por idade. Com relação aos tipos de erros, foram observadas diferenças significantes com maior número de erros entre disléxicos para erros de correspondência unívoca grafema-fonema, omissão de segmentos e correspondência fonema-grafema independente de regras. CONCLUSÃO: conclui-se que a análise dos erros ortográficos é útil para a compreensão das estratégias utilizadas e dos processos lingüísticos subjacentes às dificuldades de escrita em indivíduos com dislexia.PURPOSE: to evaluate the response pattern of dyslexic subjects in the written version of a picture naming task, by analyzing the types of orthographic errors committed. METHODS: the performance of a group of 15 dyslexics was compared to two control groups matched by age and by reading level. RESULTS: the dyslexic and the reading control groups did not differ on the number of submitted errors, but both committed more errors than the age control group. Regarding the types of orthographic errors submitted, the most frequent errors within the dyslexic individuals were: errors of univocal grapheme-phoneme correspondence, omission of segments and phoneme-grapheme correspondence regardless of any rule. CONCLUSION: it is concluded that analyzing orthographic errors is useful for understanding the used strategies and the linguistic processes underlying the writing difficulties in dyslexic subjects.

  10. La masa de los grandes impactores

    Parisi, M. G.; Brunini, A.

    Los planetas han sido formados fundamentalmente acretando masa a través de colisiones con planetesimales sólidos. La masa más grande de la distribución de planetesimales y las masas máxima y mínima de los impactores, han sido calculadas usando los valores actuales del período y de la inclinación de los planetas (Lissauer & Safronov 1991; Parisi & Brunini 1996). Recientes investigaciones han mostrado, que las órbitas de los planetas gigantes no han sufrido variaciones con el tiempo, siendo su movimiento regular durante su evolución a partir de la finalización de la etapa de acreción (Laskar 1990, 1994). Por lo tanto, la eccentricidad actual de los planetas gigantes se puede utilizar para imponer una cota máxima a las masas y velocidades orbitales de los grandes impactores. Mediante un simple modelo dinámico, y considerando lo arriba mencionado, obtenemos la cota superior para la masa del planetesimal más grande que impactó a cada planeta gigante al final de su etapa de acreción. El resultado más importante de este trabajo es la estimación de la masa máxima permitida para impactar a Júpiter, la cúal es ~ 1.136 × 10 -1, siendo en el caso de Neptuno ~ 3.99 × 10 -2 (expresada en unidades de la masa final de cada planeta). Además, fue posible obtener la velocidad orbital máxima permitida para los impactores como una función de su masa, para cada planeta. Las cotas obtenidas para la masa y velocidad de los impactores de Saturno y Urano (en unidades de la masa y velocidad final de cada planeta respectivamente) son casi las mismas que las obtenidas para Júpiter debido a que estos tres planetas poseen similar eccentricidad actual. Nuestros resultados están en buen acuerdo con los obtenidos por Lissauer & Safronov (1991). Estas cotas podrían ser utilizadas para obtener la distribución de planetesimales en el Sistema Solar primitivo.

Trata-se de pesquisa descritiva, sob abordagem qualitativa, realizada com 14 enfermeiros de UTI de um hospital privado de São Paulo. A análise dos resultados foi realizada segundo a proposta de análise de conteúdo de Bardin. Os resultados evidenciados foram: reconhecendo ser falível, reconhecendo e comunicando o erro, e omitindo o erro. Os relatos dos enfermeiros formaram a base para as considerações apontadas à luz dos referenciais bioéticos: a responsabilidade diante do erro supõe o reconhecimento das próprias vulnerabilidades, assumir o erro com responsabilidade supõe condições éticas nas relações entre as pessoas envolvidas e o erro tem um ambiente. Este estudo propicia repensar a prática de enfermagem pautada na bioética, recorrendo à análise do erro focada nas relações entre os envolvidos.

RESULTADOS: Os grupos GE1 e GE2 diferiram quanto ao desempenho nos índices na comparação entre as duas provas de fonologia aplicadas. Observou-se em todas as análises que os índices que avaliam as substituições indicaram o tipo de erro mais cometido pelas crianças com transtorno fonológico. CONCLUSÃO: Os índices foram efetivos na indicação da substituição como o erro mais ocorrente em crianças com TF. A maior ocorrência de erros de fala observada na nomeação de figuras em crianças com histórico de otite média indica que tais erros, possivelmente, estão associados à dificuldade na representação fonológica causada pela perda auditiva transitória que vivenciaram.PURPOSE: To describe articulatory indexes for the different speech errors and to verify the existence of a preferred type of error in children with speech sound disorder, according to the presence or absence of otitis media history.

  13. The problem of the Grand Unification Theory

    Science.gov (United States)

    Treder, H.-J.

    The evolution and fundamental questions of physical theories unifying the gravitational, electromagnetic, and quantum-mechanical interactions are explored, taking Pauli's aphorism as a motto: 'Let no man join what God has cast asunder.' The contributions of Faraday and Riemann, Lorentz, Einstein, and others are discussed, and the criterion of Pauli is applied to Grand Unification Theories (GUT) in general and to those seeking to link gravitation and electromagnetism in particular. Formal mathematical symmetry principles must be shown to have real physical relevance by predicting measurable phenomena not explainable without a GUT; these phenomena must be macroscopic because gravitational effects are to weak to be measured on the microscopic level. It is shown that empirical and theoretical studies of 'gravomagnetism', 'gravoelectricity', or possible links between gravoelectrity and the cosmic baryon assymmetry eventually lead back to basic questions which appear philosophical or purely mathematical but actually challenge physics to seek verifiable answers.

    At the end of inflation the Universe is frozen in a near zero-entropy state with energy density in a coherent scalar field and must be {open_quote}{open_quote}defrosted{close_quote}{close_quote} to produce the observed entropy and baryon number. We propose that the baryon asymmetry is generated by the decay of supermassive grand-unified-theory (GUT) bosons produced nonthermally in a preheating phase after inflation. We show that baryogenesis is possible for an inflaton mass of order 10{sup 13} GeV and a GUT Higgs boson mass of order 10{sup 14} GeV, thus solving many drawbacks facing GUT baryogenesis in the old reheating scenario. {copyright} {ital 1996 The American Physical Society.}

    Lawrie, Ian D

    2013-01-01

    A Unified Grand Tour of Theoretical Physics invites its readers to a guided exploration of the theoretical ideas that shape our contemporary understanding of the physical world at the fundamental level. Its central themes, comprising space-time geometry and the general relativistic account of gravity, quantum field theory and the gauge theories of fundamental forces, and statistical mechanics and the theory of phase transitions, are developed in explicit mathematical detail, with an emphasis on conceptual understanding. Straightforward treatments of the standard models of particle physics and cosmology are supplemented with introductory accounts of more speculative theories, including supersymmetry and string theory. This third edition of the Tour includes a new chapter on quantum gravity, focusing on the approach known as Loop Quantum Gravity, while new sections provide extended discussions of topics that have become prominent in recent years, such as the Higgs boson, massive neutrinos, cosmological perturba...

More trouble, lots more, "abrupt climate change," (R. B. Alley, et al. Science 03/28/03). R. Corell, Arctic Climate Impact Assessment team (ACIA), "If you want to see what will happen in the rest of the world 25 years from now just look what's happening in the Arctic," (Arctic Council meeting, Iceland, 08/03). What to do? Make abrupt Arctic climate change a grand challenge for the IPY-4 and beyond! Scientifically:Describe the "state" of the Arctic climate system as succinctly as possible and accept it as the point of departure.Develop a hypothesis and criteria what constitutes "abrupt climate change," in the Arctic that can be tested with observations. Observations: Bring to bear existing observations and coordinate new investments in observations through an IPY-4 scientific management committee. Make the new Barrow, Alaska, Global Climate Change Research Facility a major U.S. contribution and focal point for the IPY-4 in the U.S Arctic. Arctic populations, Native peoples: The people of the North are living already, daily, with wrenching change, encroaching on their habitats and cultures. For them "the earth is faster now," (I. Krupnik and D. Jolly, ARCUS, 2002). From a political, economic, social and entirely realistic perspective, an Arctic grand challenge without the total integration of the Native peoples in this effort cannot succeed. Therefore: Communications must be established, and the respective Native entities must be approached with the determination to create well founded, well functioning, enduring partnerships. In the U.S. Arctic, Barrow with its long history of involvement and active support of science and with the new global climate change research facility should be the focal point of choice Private industry: Resource extraction in the Arctic followed by oil and gas consumption, return the combustion

  7. Grand Fir Nutrient Management in the Inland Northwestern USA

    2016-11-01

    Full Text Available Grand fir (Abies grandis (Douglas ex D. Don Lindley is widely distributed in the moist forests of the Inland Northwest. It has high potential productivity, its growth being nearly equal to western white pine, the most productive species in the region. There are large standing volumes of grand fir in the region. Nutritionally, the species has higher foliage cation concentrations than associated conifers, especially potassium (K and calcium (Ca. In contrast, it has lower nitrogen (N foliage concentrations, which creates favorable nutrient balance on N-limited sites. Despite concentration differences, grand fir stores proportionally more nutrients per tree than associated species because of greater crown biomass. Although few fertilization trials have examined grand fir specifically, its response is inferred from its occurrence in many monitored mixed conifer stands. Fertilization trials including grand fir either as a major or minor component show that it has a strong diameter and height growth response ranging from 15% to 50% depending in part on site moisture availability and soil geology. Grand fir tends to have a longer response duration than other inland conifers. When executed concurrently with thinning, fertilization often increases the total response. Late rotation application of N provides solid investment returns in carefully selected stands. Although there are still challenges with the post-fertilization effects on tree mortality, grand fir will continue to be an important species with good economic values and beneficial responses to fertilization and nutrient management.

  8. Proton decay: Numerical simulations confront grand unification

    Energy Technology Data Exchange (ETDEWEB)

    Brower, R.C.; Maturana, G.; Giles, R.C.; Moriarty, K.J.M.; Samuel, S.

    The Grand Unified Theories of the electromagnetic, weak and strong interactions constitute a far reaching attempt to synthesize our knowledge of theoretical particle physics into a consistent and compelling whole. Unfortunately, many quantitative predictions of such unified theories are sensitive to the analytically intractible effects of the strong subnuclear theory (Quantum Chromodynamics or QCD). The consequence is that even ambitious experimental programs exploring weak and super-weak interaction effects often fail to give definitive theoretical tests. This paper describes large-scale calculations on a supercomputer which can help to overcome this gap between theoretical predictions and experimental results. Our focus here is on proton decay, though the methods described are useful for many weak processes. The basic algorithms for the numerical simulation of QCD are well known. We will discuss the advantages and challenges of applying these methods to weak transitions. The algorithms require a very large data base with regular data flow and are natural candidates for vectorization. Also, 32-bit floating point arithmetic is adequate. Thus they are most naturally approached using a supercomputer alone or in combination with a dedicated special purpose processor. (orig.).

  9. The grand descent has begun for CMS

    CERN Multimedia

    2006-01-01

    Until recently, the CMS experimental cavern looked relatively empty; its detector was assembled entirely at ground level, to be lowered underground in 15 sections. On 2 November, the first hadronic forward calorimeter led the way with a grand descent. The first section of the CMS detector (centre of photo) arriving from the vertical shaft, viewed from the cavern floor. There is something unusual about the construction of the CMS detector. Instead of being built in the experimental cavern, like all the other detectors in the LHC experiments, it was constructed at ground level. This was to allow for easy access during the assembly of the detector and to minimise the size of the excavated cavern. The slightly nerve-wracking task of lowering it safely into the cavern in separate sections came after the complete detector was successfully tested with a magnetic field at ground level. In the early morning of 2 November, the first section of the CMS detector began its eagerly awaited descent into the underground ca...

  11. A unified grand tour of theoretical physics

    CERN Document Server

    Griffiths, J

    2002-01-01

    Anyone offering a grand tour is faced with several options. Should they concentrate on what may be considered to be essential features, or should they attempt to present a brief glimpse of almost everything? The present offering is a compromise between these two extremes. The area considered - theoretical physics - is now such a vast subject that some kind of compromise is essential. Indeed, the field is now so wide that few could even attempt to review it in a single-authored work. My task here is to assess how well this book has succeeded in its main aim of providing a unified (though introductory) tour of this subject. Constrained within a single volume, this is clearly not an updated Landau-Lifschitz. It cannot be expected to take any particular topic to the level of recent research. Nevertheless, it does seem to cover the broad range of essential topics which now constitute the subject. It starts (most appropriately in my opinion) with geometry. It then covers classical physics, general relativity and qu...

  12. Local grand unification in the heterotic landscape

    Energy Technology Data Exchange (ETDEWEB)

    Schmidt, Jonas

    2009-07-15

    We consider the possibility that the unification of the electroweak interactions and the strong force arises from string theory, at energies significantly lower than the string scale. As a tool, an effective grand unified field theory in six dimensions is derived from an anisotropic orbifold compactification of the heterotic string. It is explicitly shown that all anomalies cancel in the model, though anomalous Abelian gauge symmetries are present locally at the boundary singularities. In the supersymmetric vacuum additional interactions arise from higher-dimensional operators. We develop methods that relate the couplings of the effective theory to the location of the vacuum, and find that unbroken discrete symmetries play an important role for the phenomenology of orbifold models. An efficient algorithm for the calculation of the superpotential to arbitrary order is developed, based on symmetry arguments. We furthermore present a correspondence between bulk fields of the orbifold model in six dimensions, and the moduli fields that arise from compactifying four internal dimensions on a manifold with non-trivial gauge background.

Tais melhorias foram desenvolvidas com base no teste do método em canteiros de obras, um ambiente no qual ele ainda não havia sido aplicado. Assim, foram investigados 19 acidentes de trabalho ocorridos em uma construtora de pequeno porte, sendo classificados os tipos de erros dos trabalhadores lesionados e de colegas de equipe que se encontravam no cenário do acidente. Os resultados indicaram que não houve nenhum erro em 70,5% das 34 vezes em que o método foi aplicado, evidenciando que as causas dos acidentes estavam fortemente associadas a fatores organizacionais. O estudo apresenta ainda recomendações para a interpretação das perguntas que constituem o método, bem como modificações em algumas dessas perguntas em comparação às versões anteriores.The objective of this study is to propose improvements in the algorithm for classifying error types of front-line workers. The improvements have been identified on the basis of testing the algorithm in construction sites, an environment where it had not been implemented it. To this end, 19 occupational accidents which occurred in a small construction company were investigated, and the error types of both injured workers and team members were classified. The results indicated that there was no error in 70.5% of the 34 times the algorithm was applied, providing evidence that the causes were strongly linked to organizational factors. Moreover, the study presents not only recommendations to facilitate the interpretation of the questions that constitute the algorithm, but also changes in some questions in comparison to the previous versions of the tool.

A frutose é um importante carboidrato da dieta, sendo encontrada principalmente nas frutas e vegetais, e é produzida no organismo a partir da glicose pela via do sorbitol. A frutose é conhecida pelos erros inatos do seu metabolismo, cujas manifestações clínicas são potencialmente graves, e por seu uso como substituta da glicose na dieta de diabéticos, visto não depender da insulina para o seu metabolismo. Nos últimos anos, especialmente em países desenvolvidos, seu consumo tem aumentado acentuadamente em virtude do emprego como adoçante em produtos industrializados. Porém, o uso excessivo de frutose não é isento de efeitos adversos, representados pelo aumento de triglicerídios e de colesterol no sangue. O conhecimento dos níveis sangüíneos normais é importante tanto para estabelecer a quantidade segura a ser administrada, como para permitir avaliar doenças metabólicas associadas à frutose.This article reviews the metabolism of fructose and sorbitol, their main clinical indications and the consequences of inadequate use. Fructose, an important carbohydrate in the diet, is present mostly in fruits and vegetables; it can also be synthesized from glucose in the organism, through the sorbitol. Fructose is known for its metabolism's inherent errors, whose clinical manifestations are potentially serious, as well as for its use as a glucose substitute in the diabetic patients' diet, due to its metabolism not being dependent from insulin. In the last years, especially in developed countries, the consumption of fructose has increased considerably, due to its use as a sweetener in industrialized foods. However, adverse side-effects may occur with the excessive ingestion of fructose, such as the increase in blood's triglycerides and cholesterol.

Em contrapartida, sua complexidade e dimensão levam a desafios na garantia da qualidade de seus resultados. O presente artigo tem por objetivo apresentar os possíveis fatores associados a erros não amostrais detectados na coleta das informações, mediante a análise de paradados e dos microdados do Censo Demográfico brasileiro de 2010. Os dados utilizados provêm das informações sobre a operação de coleta e administração da pesquisa oriundas, respectivamente, do sistema de gerenciamento de recursos humanos do pessoal de coleta e do sistema de supervisão da operação de coleta, ou seja, os paradados. Também se utilizam os microdados do universo do Censo Demográfico. Neste estudo foram analisadas as divergências observadas entre as informações coletadas pelos recenseadores e aquelas obtidas por supervisores nas reentrevistas realizadas em procedimentos de supervisão do trabalho de campo. Para análise de divergências detectadas entre os dados coletados por recenseadores e supervisores, foram empregados modelos hierárquicos generalizados. Os resultados mostram que existem diferenciais nas divergências associados à estrutura de coleta dos dados e às características dos recenseadores, supervisores e informantes, além de revelarem diferenças regionais. Fica evidente, sobretudo, uma forte influência das características do informante nas chances de ocorrência das divergências, em detrimento das características dos supervisores e recenseadores. Os resultados da modelagem estatística sugerem que as entrevistas realizadas com informantes do sexo masculino, analfabetos ou com baixa escolaridade, mais velhos e que vivem em domicílios com indicadores que refletem condições de vida menos satisfatórias apresentam aumento nas chances em favor da

    Full Text Available This article analyzes the different building stages of three large sea platforms. After studying the structure's main characteristics, preparing scale models and calculating ail the elements, platform construction was carried out in three stages: — Dry-dock construction of the hull base. — Installation in the water and finishing the structure. — Immersion and bridge installation. Finally, the necessary operations to move the platform to its definite location were carried out. The structures are formed by a parallelepiped hull of reinforced concrete, divided into compartments by means of vertical orthogonals panels on top of which 2 or 4 piles are placed to support the bridge.

    In the context of the standard SUSY GUT scenario, we present a detailed analysis of the softly broken finite supersymmetric grand unified theory. The model, albeit nonminimal, remains very rigid due to the requirement of finiteness. It is based on the SU(5) gauge group and is UV finite to all orders of perturbation theory. It contains three generations of the matter fields together with four pairs of Higgses. The requirement of UV finiteness fixes all the Yukawa couplings at the GUT scale. Imposing the condition of universality on the soft couplings at the Planck scale and then extending the condition of finiteness to them, one gets a completely finite unified theory above M{sub GUT}. This makes the fine-tuning procedure more meaningful and leads to the usual Minimal Supersymmetric Standard Model below M{sub GUT}. All the masses of the ordinary particles including Higgses are obtained due to the Higgs mechanism at the electro-weak scale. The hierarchy of quark and lepton masses is related to that of v.e.v.`s of the Higgs fields and is governed by the Higgs mixing matrix in the generation space. Superpartners develop their masses according to the RG equations starting from the soft terms at the Planck scale. The suggestion of complete finiteness and maximal simplicity of the unified theory leads to the connection between the initial values of soft SUSY breaking parameters, namely m{sub 0}{sup 2}=1/3m{sub 1/2}{sup 2}, A{sub t}=A{sub b}=A{sub {tau}}=-m{sub 1/2}, B=-m{sub 1/2}, so that the number of free parameters is less than that of the MSSM.

  4. The 1929 Grand Banks submarine landslide revisited

    Science.gov (United States)

    Schulten, Irena; Mosher, David C.; Krastel, Sebastian; Piper, David J. W.; Kienast, Markus

    2017-04-01

    On November 18th, 1929 a large submarine landslide occurred along the St. Pierre Slope of the southwestern Grand Banks of Newfoundland, as a result of a Mw 7.2 earthquake. This submarine landslide led to the first recognition of naturally-occurring submarine turbidity currents and is one of the few landslides known to have generated a tsunami. The event caused 28 causalities in Newfoundland and severe infrastructural damage. Earlier investigations of the area identified widely distributed shallow mass failures (15 - 20 m high escarpments), but no evidence of a larger headscarp. It is difficult to conceive, therefore, how this distributed shallow failure that rapidly evolved into a turbidity current would have generated a tsunami. It is hypothesised in this study that a deeper rooted sediment failure ( 500 m), involving faulting and mass-rotation, was involved in the sediment failure and this displacement generated the tsunami. In order to test this hypothesis, the volume and kinematics of the 1929 slope failure are analysed by means of recently acquired high resolution seismic reflection and multibeam swath bathymetry data, in addition to a significant volume of legacy data. The data allow determination of: 1) the dimension of the failure area, 2) the thickness and volume of failed sediment on St. Pierre Slope, 3) fault patterns and displacements, and 4) styles of sediment failure involved. Shallow (20 m high) sinuous escarpments and a number of faults are observed along the upper St. Pierre Slope (500 - 2 500 m water depth). The uppermost and largest of these escarpments shows association with a fault system. Preliminary results, therefore, indicate a complex sediment failure pattern along the St. Pierre Slope, possibly involving a deep-seated decollement and mobilization of a large volume of surficial sediment through retrogressive failure. Causes for the tsunami are yet to be determined.

  5. Thermomechanical models of the Rio Grande rift

    1980-01-01

    Fully two-dimensional, coupled thermochemical solutions of a continental rift and platform are used to model the crust and mantle structure of a hot, buoyant mantle diapir beneath the Rio Grande rift. The thermomechanical model includes both linear and nonlinear laws of the Weertman type relating shear stress and creep strain rate, viscosity which depends on temperature and pressure, and activation energy, temperature-dependent thermal conductivity, temperature-dependent coefficient of thermal expansion, the Boussinesq approximation for thermal bouyancy, material convection using a stress rate that is invariant to rigid rotations, an elastically deformable crust, and a free surface. The model determines the free surface velocities, solid state flow field in the mantle, and viscosity structure of lithosphere and asthenosphere. Regional topography and crustal heat flow are simulated. A suite of symmetric models, assumes continental geotherms on the right and the successively increasing rift geotherms on the left. These models predict an asthenospheric flow field which transfers cold material laterally toward the rift at > 300 km, hot, buoyant material approx. 200 km wide which ascends vertically at rates of 1 km/my between 175 to 325 km, and spreads laterally away from the rift at the base of the lithosphere. Crustal spreading rates are similar to uplift rates. The lithosphere acts as stiff, elastic cap, damping upward motion through decreased velocities of 1 km/10 my and spreading uplift laterally. A parameter study varying material coefficients for the Weertman flow law suggests asthenospheric viscosities of approx. 10/sup 22/ to 10/sup 23/ poise. Similar studies predict crustal viscosities of approx. 10/sup 25/ poise. The buoyant process of mantle flow narrows and concentrates heat transport beneath the rift, increases upward velocity, and broadly arches the lithosphere. 10 figures, 1 table.

    Reibel, Tracy; Skinner, Lesley; Emery, Jon

    2010-04-01

    The hospital 'grand round' concept was applied to a general practice continuing professional development activity. Interactive learning sessions were developed to deliver evidence based medicine clinical education for general practitioners and general practice learners (registrars/medical students). The acceptability of the GP grand round format was examined through analysis of participant responses to learning objectives. The article explores some of the issues associated with delivery of small group case based discussion. Evaluations demonstrated that participants in the grand round valued the opportunity to interact with other participants in a small group format, exchanged and shared knowledge and had their learning needs met. The overall quality of the learning experience for the majority of participants was either good or excellent. The application of vertically integrated continuing professional development through a grand round format appears acceptable and effective.

    SO(11) gauge-Higgs grand unification is formulated in the 6-dimensional hybrid warped space in which the 5th and 6th dimensions play as the electroweak and grand-unification dimensions. Fermions are introduced in 32, 11, and 1 of SO(11). Small neutrino masses naturally emerge as a result of a new seesaw mechanism in the gauge-Higgs unification which is characterized by a 3 × 3 mass matrix.

    After almost 13 years in Saturn orbit, the Cassini-Huygens mission has entered its final year of data collection. Cassini will return its final bits of unique data on 15 September 2017 as it plunges into Saturn’s atmosphere, vaporizing and satisfying planetary protection requirements.Since early 2016 Cassini’s orbital inclination was slowly increased towards its final inclination. In November Cassini transitioned to a series of 20 orbits with periapses just outside Saturn's F ring that included some of the closest flybys of the tiny ring moons and excellent views of the F ring and outer A ring.Cassini's final close flyby of Titan in April 2017 propelled it across Saturn’s main rings and into its final orbits. Cassini's Grand Finale began in April 2017 and is comprised of 22 orbits at an inclination of 63 degrees. Cassini is repeatedly diving between the innermost ring and Saturn's upper atmosphere providing insights into fundamental questions unattainable during the rest of the mission. It is the first spacecraft to explore this region.These close orbits provide the highest resolution observations of both the rings and Saturn, and direct in situ sampling of the ring particles' composition, plasma, Saturn's exosphere and the innermost radiation belts. Saturn's gravitational field will be measured to unprecedented accuracy, providing information on Saturn's interior structure and mass distribution in the rings. Probing the magnetic field will give insight into the nature of the magnetic dynamo and the true rotation rate of Saturn's interior. The ion and neutral mass spectrometer will sniff the exosphere and upper atmosphere and examine water-based molecules originating from the rings. The cosmic dust analyzer will sample particle composition from different parts of the main rings.Recent science highlights and science objectives from Cassini’s final orbits will be discussed.This work was carried out in part at the Jet Propulsion Laboratory, California

  7. 3D View of Grand Canyon, Arizona

    2000-01-01

    The Grand Canyon is one of North America's most spectacular geologic features. Carved primarily by the Colorado River over the past six million years, the canyon sports vertical drops of 5,000 feet and spans a 445-kilometer-long stretch of Arizona desert. The strata along the steep walls of the canyon form a record of geologic time from the Paleozoic Era (250 million years ago) to the Precambrian (1.7 billion years ago).The above view was acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument aboard the Terra spacecraft. Visible and near infrared data were combined to form an image that simulates the natural colors of water and vegetation. Rock colors, however, are not accurate. The image data were combined with elevation data to produce this perspective view, with no vertical exaggeration, looking from above the South Rim up Bright Angel Canyon towards the North Rim. The light lines on the plateau at lower right are the roads around the Canyon View Information Plaza. The Bright Angel Trail, which reaches the Colorado in 11.3 kilometers, can be seen dropping into the canyon over Plateau Point at bottom center. The blue and black areas on the North Rim indicate a forest fire that was smoldering as the data were acquired on May 12, 2000.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as

    2006-12-01

    The Rio Grande River stretches over 2000 miles from the southern Rocky Mountains in Colorado to the tip of Texas where the Rio Grande meets the Gulf of Mexico. It is the natural boundary between U.S. and Mexico from El Paso, TX, to Brownsville, TX. The communities along the border heavily rely upon the Rio Grande as a primary source of water for consumption, agricultural uses, supporting wildlife and recreation. For many years the Rio Grande has been polluted with municipal, industrial, agricultural and farming contaminants from both sides of the border. This pollution has led to the extinction or reduction of certain wildlife species as well as affecting the health of the residences along the border. Even though great strides have been made in monitoring the Rio Grande, there has been a lack of intense monitoring data collection for pollutants such as pesticides. Three sampling sites including Manadas Creek, the Rio Grande River at International Bridge I, and USGS monitoring site 08459200 off of Highway 83 were chosen. The water quality parameters focused include temperature, pH, conductivity, dissolve oxygen (DO), salinity, total dissolved solids, nutrients, metals and pesticides. Preliminary results have shown elevated concentration of total phosphorus and ortho-phosphorus in the Manadas Creek site. Organochlorinated pesticides such as heptachlor and 4, 4 DDE were detected at various concentrations at all sites and endrin aldehyde was found at Manadas Creek site. This research has provided more information on the current chemical contamination level of the Rio Grande in the Laredo area.

Assim sendo, este experimento foi realizado com larvas de Lophiosilurus alexandri pacamã objetivando determinar algumas fontes de erros amostrais na medição do tamanho e do peso de larvas de peixes. Avaliou-se cinco possíveis fontes de erros. O primeiro foi o erro na medida dos comprimentos total e padrão, devido a acuidade de medição de dois observadores. O segundo, foi o erro na medida dos comprimentos total e padrão, devido ao encolhimento proporcionado pelo fixador formalina a 10%. O terceiro foi o erro devido a duas formas de secagem das larvas na obtenção da biomassa. O quarto experimento foi sobre a influência do tamanho e do agrupamento das larvas na obtenção de pesos. Por fim, o quinto teste observou a alteração da biomassa devido ao tempo de permanência das larvas na balança. Pôde-se verificar a importância de se determinar e cumprir um protocolo de amostagem para medições de larvas de peixes. Por apresentarem tamanho e peso reduzidos, uma pequena variação na condição da mensuração, pode alterar substancialmente o resultado, pois alterações significativas foram verificadas para os testes acima referidos.Experiments in the cultivation or ecological with fish larvae, invariably use the length and weight with parameters.

  13. The Grand Tour via Geodesic Interpolation of 2-frames

    Asimov, Daniel; Buja, Andreas

    1994-01-01

    Grand tours are a class of methods for visualizing multivariate data, or any finite set of points in n-space. The idea is to create an animation of data projections by moving a 2-dimensional projection plane through n-space. The path of planes used in the animation is chosen so that it becomes dense, that is, it comes arbitrarily close to any plane. One of the original inspirations for the grand tour was the experience of trying to comprehend an abstract sculpture in a museum. One tends to walk around the sculpture, viewing it from many different angles. A useful class of grand tours is based on the idea of continuously interpolating an infinite sequence of randomly chosen planes. Visiting randomly (more precisely: uniformly) distributed planes guarantees denseness of the interpolating path. In computer implementations, 2-dimensional orthogonal projections are specified by two 1-dimensional projections which map to the horizontal and vertical screen dimensions, respectively. Hence, a grand tour is specified by a path of pairs of orthonormal projection vectors. This paper describes an interpolation scheme for smoothly connecting two pairs of orthonormal vectors, and thus for constructing interpolating grand tours. The scheme is optimal in the sense that connecting paths are geodesics in a natural Riemannian geometry.

    The Grand Junction Projects Office (GJPO) is located in Mesa County, Colorado, immediately south and west of the Grand Junction city limits. The US Atomic Energy Commission (AEC) established the Colorado Raw Materials Office at the present-day Grand Junction Projects Office in 1947, to aid in the development of a viable domestic uranium industry. Activities at the site included sampling uranium concentrate; pilot-plant milling research, including testing and processing of uranium ores; and operation of a uranium mill pilot plant from 1954 to 1958. The last shipment of uranium concentrate was sent from GJPO in January, 1975. Since that time the site has been utilized to support various DOE programs, such as the former National Uranium Resource Evaluation (NURE) Program, the Uranium Mill Tailings Remedial Action Project (UMTRAP), the Surplus Facilities Management Program (SFMP), and the Technical Measurements Center (TMC). All known contamination at GJPO is believed to be the result of the past uranium milling, analyses, and storage activities. Hazards associated with the wastes impounded at GJPO include surface and ground-water contamination and potential radon and gamma-radiation exposure. This report documents the results of the Baseline Environmental Audit conducted at Grand Junction Projects Office (GJPO) located in Grand Junction, Colorado. The Grand Junction Baseline Environmental Audit was conducted from May 28 to June 12, 1991, by the Office of Environmental Audit (EH-24). This Audit evaluated environmental programs and activities at GJPO, as well as GJPO activities at the State-Owned Temporary Repository. 4 figs., 12 tabs.

    OpenAIRE

    Sheehan, Helena

    1998-01-01

    Reading the Communist Manifesto today, it is impossible not to be struck by the confidence with which it conceptualises history. The positive energy of this bold grand narrative stands in such stark contrast to the negative and jaded mentality of our times, which conceives of grand narratives only to tell us that there can be none. Such talk as there is of history today is more likely to be of "the end of history". There are three senses in which references to the end of history feature in co...

    In the context of the spectral action and the noncommutative geometry approach to the standard model, we build a model based on a larger symmetry. With this grand symmetry it is natural to have the scalar field necessary to obtain the Higgs mass in the vicinity of 126 GeV. This larger symmetry mixes gauge and spin degrees of freedom without introducing extra fermions. Requiring the noncommutative space to be an almost commutative geometry (i.e. the product of manifold by a finite dimensional internal space) gives conditions for the breaking of this grand symmetry to the standard model.

    Full Text Available The aim of this brief essay is to focus on the relation between the meaning of reality and illusion in the movie La Grande Illusion (1937 by Jean Renoir and therefore to find how these ideas of the author may be productive in a thought about the imaginary. After a short look on the movies made at that time on the First World War, there is an overview of the French director poetics, which redefines the conception of the realism, contextualizing its work at the point of convergence of two imaginary “technological lines”, the cinema and the aviation. It follows the analysis of the movie and the illusions, as social largely shared imaginaries, described by the author. In the end it is showed the importance and the of illusion in Renoir’s poetics. Beyond the relationship realityfiction, he thought a dynamic reciprocity among illusion and reality: so that the reality is as “illusion” (a ruled horizon in which it is possible to enjoy a world of play and the illusion as an activity creating contents of “reality”.

The first day and a half focused on applications. Presentations were given by speakers from universities, national laboratories, and government agencies actively involved in Grand Challenge research. Five areas of research were covered: environmental and earth sciences; computational physics; computational biology, chemistry, and materials sciences; computational fluid and plasma dynamics; and applications of artificial intelligence. The next day and a half was spent in working groups in which the applications researchers were joined by software technologists. Nine breakout sessions took place: I/0, Data, and File Systems; Parallel Programming Paradigms; Performance Characterization and Evaluation of Massively Parallel Processing Applications; Program Development Tools; Building Multidisciplinary Applications; Algorithm and Libraries I; Algorithms and Libraries II; Graphics and Visualization; and National HPCC Infrastructure.

  11. Brighty, donkeys and conservation in the Grand Canyon.

    Science.gov (United States)

    Wills, John

    2006-09-01

    The Grand Canyon is a vast place. It is almost incomprehensible in size. And yet it can also seem strangely crowded. Millions of tourists flock to the Grand Canyon in northern Arizona every year. In 1999, almost 5 million people visited, the highest figure in Canyon history. And each one of them expected to see a wild, free and untrammelled landscape. Despite the obvious natural resources, this expectation has proved anything but easy to satisfy. The US National Park Service (NPS), responsible for the management of most large North American parks (along with several historic sites and museums), has struggled to make or keep the canyon "grand". Park rangers have grappled with a multitude of issues during the past century, including automobile congestion, drying of the Colorado River and uranium mining inside the park. Conservation has posed a unique set of challenges. On a fundamental level, "restoring" the Grand Canyon to its "original" wilderness setting has proved intensely problematic. In the field of wildlife management, restoring the Canyon to its pre-Columbian splendour has entailed some tough decisions--none more so than a 1976 plan to eliminate a sizeable population of feral burros (wild donkeys) roaming the preserve, animals classified as exotics by the NPS.

After detailed investigations of the knee in the spectrum with KASCADE and EAS-TOP experiments, the main goal of KASCADE-Grande is to provide conclusive results on the knee region by detecting the expected iron knee in the spectrum at around 10{sup 17} eV, and measuring the composition in the possible transition region between galactic and extragalactic components. Due to its multi-component characteristics, basically the former KASCADE experiment enriched by two new arrays of scintillator detectors (Grande and Piccolo), with the aim of providing a large acceptance area (0.5 km{sup 2}) and prompt trigger signal, KASCADE-Grande is a suitable array to provide refined measurements in the 10{sup 16}-10{sup 18} eV region. In the following, we briefly report on the characteristics of the detector, its performance, and first results based on 2 years of data taking.

Por un lado, se compara un grupo de grandes consumidores de servicios de salud, a nivel de número de consultas, con un grupo control en términos de funcionamiento familiar y actitudes hacia los médicos y la Medicina; por otro lado, se estudia la relación entre la dinámica familiar y las actitudes hacia la Medicina y los médicos en el grupo de los grandes consumidores. Los resultados muestran que los dos grupos de usuarios son significativamente diferentes; además, en el grupo de grandes consumidores el funcionamiento familiar problemático parece ser un factor intermediario en el desarrollo de actitudes menos negativas hacia los médicos y la Medicina. Se discuten las implicaciones que los resultados tienen a nivel de intervención terapéutica.

This descriptive and exploratory study assesses four scenarios showing situations from nursing practice. The study group was composed of 256 professionals and 89 questionnaires were analyzed. The answers given by the registered nurses were compared with those of licensed practical nurses and care aids. They should express their opinion if the situations represented a medication error or not, if it had to be communicated to the physician or an incident report had to be written. The two groups showed uniform answers. They expressed the same doubts to label the situation as an error and which measures should be taken, suggesting the need for further discussion on the matter within the institution.El error de medicación se define como cualquier error en el proceso de prescripción, dispensación o administración de una medicación, pudiendo o no traer consecuencias serias.

    2014-03-01

    The China Grand Canal is one of the earliest canals in the world, having lasted for nearly 3000 years. Even its section canals have a rich history, such as the North-South Grand Canal that was established during the Sui Dynasty, whereas the Beijing-Hangzhou Canal was excavated during the Yuan Dynasty and the east line of the South-to-North Water Diversion. As one of the longest in the world, the China Grand Canal's total length is over 3500 kilometers. This length includes the navigable, unnavigable, and underground sections. Making the best use of situations and according to local conditions, the Chinese people harmoniously constructed the Beijing-Hangzhou Canal with nature. Tens of millions of workers took nearly 3000 years to complete the great shipping system. Navigable sections still exist for up to 900 kilometers and the volume of freight traffic is approximately 300 million tons. The canal remains the main logistical channel of the North-to-South Coal Transportation, South-to-North Water Diversion, and resources circulation. To date, China is promoting the success of heritage application. Part of these efforts is the declaration of the China Grand Canal as a World Cultural Heritage by 2014. In addition, the east route of the South-to-North Water Transfer project is planned to be navigable by 2016. The ancient Beijing-Hangzhou Grand Canal will usher in the new ecological civilization and cultural revival along the canal. This paper presents technical methods of water environment evolution research on the river system, river, and water quality along the Beijing-Hangzhou Canal through the integration of historical literature and modern remote sensing image data. The study carried out water environment investigation and analysis along the Beijing-Hangzhou canal by using ETM, SPOT image data, and GPS measurement data.

Dessa forma, realizou-se um estudo transversal de base populacional envolvendo a saúde da população adulta residente na zona urbana da cidade de Pelotas, Rio Grande do Sul, Brasil, com o objetivo de verificar a evolução nos níveis de cobertura do exame citopatológico. Investigaram-se fatores associados com a não realização do procedimento. Considerou-se exame citopatológico atualizado aquele realizado nos últimos três anos. A amostra foi constituída por 1.122 mulheres entre 20 e 69 anos, sendo que 72,2% apresentavam exame citopatológico atualizado, 16,6% atrasado e 11,2% nunca o haviam realizado. A não realização do procedimento esteve associada com baixa inserção social e idade avançada. A regressão logística destacou o efeito independente de classe social, baixa renda familiar, idade, cor da pele, estado civil e ausência de consultas médicas no último ano. Contudo, desapareceu o efeito detectado em mulheres com doenças crônicas. Comparando-se os resultados do estudo realizado em 1992 com o atual, observa-se que a cobertura do exame aumentou de 65,0% para 72,2% (1992 para 1999/2000, entretanto, não atingiu os níveis efetivos para evitar câncer de colo uterino.In Brazil, the effectiveness of preventive public heath programs and actions is rarely evaluated.

    Full Text Available O pé é a base estrutural de todo o corpo humano e um dos sistemas vitais mais negligenciados, mas, ainda assim capaz de exercer todas as suas funções. No intuito de proteger os pés e evitar as lesões surge o calçado. Em contrapartida, existe uma padronização excessiva deste artefato que atende apenas a um segmento da população. Embora existam vários estudos no Brasil que versem sobre a ergonomia e usabilidade do calçado, percebe-se a necessidade de adequação antropométrica deste produto. Com base nas diferenças entre a antropometria de diversas etnias e biótipos percebe-se que os calçados devem possuir dimensões e formatos de acordo com a morfologia do pé de cada população. O objetivo deste estudo foi medir os pés da população feminina urbana da cidade de Campina Grande-PB por meio de técnicas antropométricas e comparar estas medidas com a NBR 15159:2013 a fim de compreender a relação entre a influência do perímetro dos metatarsos sob o conforto dos calçados. O método utilizado possui natureza aplicada e abordagem mista, caracterizada por procedimentos metodológicos como levantamento bibliográfico e survey. A amostra foi definida pela estatística probabilística, composta por 408 mulheres com idade entre 15 e 44 anos, residentes fixas ou temporárias na cidade de Campina Grande-PB. Os resultados mostraram diferenças entre as dimensões do pé direito e o pé esquerdo, bem como identificaram uma discrepância entre as medidas do perímetro do metatarso quando comparado com a norma brasileira. Portanto, conclui-se que essas diferenças são refletidas na sensação de desconforto proporcionada pelos calçados, além de propiciar o surgimento de anomalias e deformidade dos pés como as calosidades e bolhas.

    Full Text Available Estudos sobre cinética de dessorção de potássio em solos podem contribuir para o melhor entendimento da disponibilidade desse nutriente no solo para as plantas. Este trabalho, realizado em 1993, teve por objetivos investigar a cinética de liberação de potássio em três solos do Rio Grande do Sul e comparar quatro equações para descrevê-la. O experimento utilizou amostras superficiais (0-20 cm dos horizonte A de um vertissolo, de um podzólico e de um latossolo. A dessorção do potássio foi quantificada desde um minuto até 2.400 horas, usando-se resina trocadora de cátions (IR-120. O K trocável nos três solos foi liberado em 12 minutos de equilíbrio com a resina H-saturada. As quantidades cumulativas de potássio não-trocável liberadas dos solos decresceram, na seqüência vertissolo (436 mg kg-1 de K > podzólico (64 mg kg-1 de K > latossolo (46 mg kg-1 de K. A equação parabólica de difusão foi a mais apropriada para descrever a cinética de liberação do potássio não-trocável dos solos, pelo maior valor do coeficiente de correlação e pelo menor valor do erro-padrão da estimativa. As taxas de liberação do potássio não-trocável dos solos, estimadas por esta equação, foram de 2,09 x 10-2 h-1, para o vertissolo; de 1,89 x 10-2 h-1, para o podzólico, e de 0,97 x 10-2 h-1, para o latossolo.

    KASCADE-Grande is a multi detector setup for the investigation of extensive air showers in the primary energy range of the knee including energies around the so-called second knee. With the data of the 700 . 700 m{sup 2} large Grande array shower core position, shower direction, and the total number of electrons are reconstructed for events with primary energy above 10{sup 16.5} eV. In addition, the experiment consists of different detector setups for measuring muons at various energy thresholds between 230 MeV and 2.4 GeV. These information are used to estimate the muon shower size as well as observables sensitive to differences of hadronic interaction models embedded in shower simulation codes. We report the goals and the status of the different muon measurements at KASCADE-Gran0008.

    The harmonic superposition method provides a unified framework to the equilibrium and relaxation kinetics on complex potential energy landscapes. Here we extend it to grand-canonical statistical ensembles governed by chemical potentials or chemical potential differences, by sampling energy minima corresponding to the various relevant sizes or compositions. The method is applied and validated against conventional Monte Carlo simulations for the problems of chemical equilibrium in nanoalloys and hydrogen absorption in bulk and nanoscale palladium.

  6. Pequenas e grandes saúdes: uma leitura nietzschiana

    Directory of Open Access Journals (Sweden)

    Emília Carvalho Leitão Biato

    Full Text Available Resumo Este artigo objetiva problematizar o conceito de saúde, entendendo-o como múltiplo, plural. Para isso, adota o pensamento filosófico de Friedrich Nietzsche como ferramenta analítica, permitindo-nos chegar a uma tipologia que envolve pequenas e grandes saúdes. Enquanto a primeira é normativa e sustentada por um ideal de cura, a segunda passa a ser compreendida enquanto força expansiva, como um estado a que continuamente se conquista. Se, por um lado, uma saúde apequenada obedece a um script prévio de moralização da vida, uma grande saúde diz respeito à expansão daquilo que vive, que afirma seu caráter criador e não instituído pelo rebanho. A concepção de uma grande saúde vai ao encontro da superação dos modelos imperativos que se fixam nas práticas fundadas na biomedicina, aproximando-se das ações coletivas em saúde. No entanto, se por um lado esse movimento amplia o caráter coparticipativo entre equipe e usuários do sistema de saúde, ele carece, de outro, de maior radicalidade no que tange aos rompimentos com o caráter moral dos processos de saúde-doença. Ao não permitir a recusa de altos e baixos próprios à vida, uma grande saúde compreende como necessária a incorporação da dor e do sofrimento implicados em movimentos de individuação.

    The Northwest Power Planning Council (NPPC) identified supplementation as a high priority to achieve its goal of increasing runs of anadromous fish in the Columbia Basin. Supplementation activities in the Lostine River and associated monitoring and evaluation conducted by the Nez Perce Tribe relate directly to the needs addressed in the Columbia River Basin Fish and Wildlife Program (NPPC 1994). Measure 7.4L.1 of the Program mandates that appropriate research accompany any proposed supplementation. In addition, measure 7.3B.2 of the Program stresses the need for evaluating supplementation projects to assess their ability to increase production. Finally, Section 7.4D.3 encourages the study of hatchery rearing and release strategies to improve survival and adaptation of cultured fish. In 1997, Oregon Department of Fisheries and Wildlife (ODFW) requested a modification of Permit 1011 to allow the take of adult spring chinook salmon. In 1998, the Nez Perce Tribe also requested a permit specific to activities on Lostine River. The permit was issued in 2000. A special condition in the permits required the development of a long term management plan for the spring chinook salmon of the Grande Ronde Basin. The Nez Perce Tribe, ODFW, and the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) completed a formal long range plan entitled ''Grande Ronde Basin Endemic Spring Chinook Salmon Supplementation Program''. The program proposes to increase the survival of spring chinook salmon in the Grand Ronde Basin through hatchery intervention. Adult salmon from the Lostine River, Catherine Creek, and the Upper Grande Ronde River are used for a conventional supplementation program in the basin. The Nez Perce program currently operates under the ESA Section 10 Permit 1149.

    Executive SummaryThe U.S. Geological Survey (USGS) has a long history of advancing the traditional Earth science disciplines and identifying opportunities to integrate USGS science across disciplines to address complex societal problems. The USGS science strategy for 2007–2017 laid out key challenges in disciplinary and interdisciplinary arenas, culminating in a call for increased focus on a number of crosscutting science directions. Ten years on, to further the goal of integrated science and at the request of the Executive Leadership Team (ELT), a workshop with three dozen invited scientists spanning different disciplines and career stages in the Bureau convened on February 7–10, 2017, at the USGS John Wesley Powell Center for Analysis and Synthesis in Fort Collins, Colorado.The workshop focused on identifying “grand challenges” for integrated USGS science. Individual participants identified nearly 70 potential grand challenges before the workshop and through workshop discussions. After discussion, four overarching grand challenges emerged:Natural resource security,Societal risk from existing and emerging threats,Smart infrastructure development, andAnticipatory science for changing landscapes.Participants also identified a “comprehensive science challenge” that highlights the development of integrative science, data, models, and tools—all interacting in a modular framework—that can be used to address these and other future grand challenges:Earth Monitoring, Analyses, and Projections (EarthMAP)EarthMAP is our long-term vision for an integrated scientific framework that spans traditional scientific boundaries and disciplines, and integrates the full portfolio of USGS science: research, monitoring, assessment, analysis, and information delivery.The Department of Interior, and the Nation in general, have a vast array of information needs. The USGS meets these needs by having a broadly trained and agile scientific workforce. Encouraging and supporting

  13. Basement structures over Rio Grande Rise from gravity inversion

    The basement depth in the Rio Grande Rise (RGR), South Atlantic, is estimated from combining gravity data obtained from satellite altimetry, marine surveys, bathymetry, sediment thickness and crustal thickness information. We formulate a crustal model of the region by inverse gravity modeling. The effect of the sediment layer is evaluated using the global sediment thickness model of National Oceanic and Atmospheric Administration (NOAA) and fitting the sediment compaction model to observed density values from Deep Sea Drilling Project (DSDP) reports. The Global Relief Model ETOPO1 and constraining data from seismic interpretation on crustal thickness are integrated in the inversion process. The modeled Moho depth values vary between 6 and 27 km over the area, being thicker under the RGR and also in the direction of São Paulo Plateau. The inversion for the gravity-equivalent basement topography is applied to gravity residual data, which is free from the gravity effect of sediments and from the gravity effect of the estimated Moho interface. We find several short-wavelengths structures not present in the bathymetry data. Our model shows a rift crossing the entire Rio Grande Rise deeper than previously presented in literature, with depths up to 5 km in the East Rio Grande Rise (ERGR) and deeper in the West Rio Grande Rise (WRGR), reaching 6.4 km. An interesting NS structure that goes from 34°S and extends through de São Paulo Ridge may be related to the South Atlantic Opening and could reveal an extinct spreading center.

These relations suggest that the fissures are forming in response to localized differential compaction caused by localized variations of aquifer-system thickness. -from Authors

    Full Text Available Nenhuma atividade empresarial nos dias atuais pode ser implementada sem que se levem em conta os aspectos de sustentabilidade. Esse conceito que nasceu do desenvolvimento sustentável dos anos 1970 e 1980 e que ficou consagrado no conceito dos três pilares de Jonh Elkington – econômico, social e ambiental, a “triple bottom line”, é um condicionante para todos os tipos de empreendimentos, especialmente para as grandes usinas hidrelétricas. As grandes usinas hidrelétricas foram por um tempo os grandes vilões do desenvolvimento, por causa da ênfase exagerada dada aos impactos que causam nas pessoas e no meio ambiente. Essa pecha que acometeu as usinas hidrelétricas, causada em grande parte por causa de alguns empreendimentos mal planejados, precisa ser revertida. Por outro lado, usinas hidrelétricas são formas de energia limpa e renovável, com mínima agressão ao meio ambiente, e menor dano às populações afetadas, se bem planejadas. Torna-se importante analisar os aspectos de sustentabilidade associados a esses empreendimentos. Existem arcabouços dedicados a fazer a análise dos aspectos de sustentabilidade de aproveitamentos hidrelétricos. Nesse trabalho é feita uma comparação entre duas ferramentas para avaliação de sustentabilidade em hidrelétricas, analisando prós e contras, facilidades e dificuldades relativas à aplicação destas.DOI:10.5585/gep.v3i1.81

    The Effects of Water Markets: Evidence from the Rio GrandePeter Debaere, University of Virginia Tianshu Li, University of Virginia The Rio Grande water market is one of the oldest water markets in the United States. Employing techniques from the social sciences, we present the first difference-in-difference analysis of the actual impact of water markets on production. We compare from 1954 to 2012 the crop composition in counties in the Rio Grande water market with those in their neighboring control counties before and after the water market was established in 1971. We provide evidence that water markets can facilitate a shift from crops that are on average more to ones that are less water intensive, or, alternatively, from crops that are on average less to ones that are more productive in terms of $ generated per unit of water. In addition, we find that such reallocations are especially prevalent in times of drought. Our findings supports water markets as a tool to manage water more effectively, which is one of the main challenges of an increasingly water-strapped world.

  2. Frequency and initiation of debris flows in Grand Canyon, Arizona

    Science.gov (United States)

    Griffiths, Peter G.; Webb, Robert H.; Melis, Theodore S.

    2004-12-01

    Debris flows from 740 tributaries transport sediment into the Colorado River in Grand Canyon, Arizona, creating rapids that control its longitudinal profile. Debris flows mostly occur when runoff triggers failures in colluvium by a process termed "the fire hose effect." Debris flows originate from a limited number of geologic strata, almost exclusively shales or other clay-rich, fine-grained formations. Observations from 1984 through 2003 provide a 20 year record of all debris flows that reached the Colorado River in Grand Canyon, and repeat photography provides a 100 year record of debris flows from 147 tributaries. Observed frequencies are 5.1 events/year from 1984 to 2003, and historic frequencies are 5.0 events/year from 1890 to 1983. Logistic regression is used to model historic frequencies based on drainage basin parameters observed to control debris flow initiation and transport. From 5 to 7 of the 16 parameters evaluated are statistically significant, including drainage area, basin relief, and the height of and gradient below debris flow source areas, variables which reflect transport distance and potential energy. The aspect of the river channel, which at least partially reflects storm movement within the canyon, is also significant. Model results are used to calculate the probability of debris flow occurrence at the river over a century for all 740 tributaries. Owing to the variability of underlying geomorphic controls, the distribution of this probability is not uniform among tributaries of the Colorado River in Grand Canyon.

    We have designed and constructed a new beam line which can accomplish both lateral and angular dispersion matching with the Grand Raiden spectrometer. In dispersive mode, lateral and angular dispersions of the beam line are b sub 1 sub 6 =37.1 m and b sub 2 sub 6 =-20.0 rad, respectively, to satisfy matching conditions for Grand Raiden. In achromatic mode, the beam line satisfies the double achromatic condition of b sub 1 sub 6 =b sub 2 sub 6 =0. The magnifications of the beam line are (M sub x ,M sub y)=(-0.98,0.89) and (-1.00,-0.99) for dispersive and achromatic modes, respectively.

    The US Department of Energy (DOE) has prepared a sitewide environmental assessment (EA) of the proposed action to continue and expand present-day activities on the DOE Grand Junction Projects Office (GJPO) facility in Grand Junction, Colorado. Because DOE-GJPO regularly proposes and conducts many different on-site activities, DOE decided to evaluate these activities in one sitewide EA rather than in multiple, activity-specific documents. On the basis of the information and analyses presented in the EA, DOE has determined that the proposed action does not constitute a major Federal action significantly affecting the quality of the human environment, as defined by the National Environmental Policy Act (NEPA) of 1969. Therefore, preparation of an environmental impact statement is not required for facility operations, and DOE is issuing this Finding of No Significant Impact (FONSI).

  5. Microbial contamination and chemical toxicity of the Rio Grande

    Full Text Available Abstract Background The Rio Grande River is the natural boundary between U.S. and Mexico from El Paso, TX to Brownsville, TX. and is one of the major water resources of the area. Agriculture, farming, maquiladora industry, domestic activities, as well as differences in disposal regulations and enforcement increase the contamination potential of water supplies along the border region. Therefore, continuous and accurate assessment of the quality of water supplies is of paramount importance. The objectives of this study were to monitor water quality of the Rio Grande and to determine if any correlations exist between fecal coliforms, E. coli, chemical toxicity as determined by Botsford's assay, H. pylori presence, and environmental parameters. Seven sites along a 112-Km segment of the Rio Grande from Sunland Park, NM to Fort Hancock, TX were sampled on a monthly basis between January 2000 and December 2002. Results The results showed great variability in the number of fecal coliforms, and E. coli on a month-to-month basis. Fecal coliforms ranged between 0–106 CFU/100 ml while E. coli ranged between 6 to > 2419 MPN. H. pylori showed positive detection for all the sites at different times. Toxicity ranged between 0 to 94% of inhibition capacity (IC. Since values above 50% are considered to be toxic, most of the sites displayed significant chemical toxicity at different times of the year. No significant correlations were observed between microbial indicators and chemical toxicity. Conclusion The results of the present study indicate that the 112-Km segment of the Rio Grande river from Sunland Park, NM to Fort Hancock, TX exceeds the standards for contact recreation water on a continuous basis. In addition, the presence of chemical toxicity in most sites along the 112-Km segment indicates that water quality is an area of concern for the bi-national region. The presence of H. pylori adds to the potential health hazards of the Rio Grande. Since no

  11. Fostering Scientific Literacy: Establishing Social Relevance via the Grand Challenges

    Science.gov (United States)

    Lyford, M. E.; Myers, J. D.; Buss, A.

    2010-12-01

    Numerous studies and polls suggest the general public’s understanding of science and scientific literacy remain woefully inadequate despite repeated calls for improvement over the last 150 years. This inability to improve scientific literacy significantly is a complex problem likely driven by a number of factors. However, we argue that past calls and efforts for improving scientific literacy have failed to: 1) articulate a truly meaningful justification for society to foster a scientifically literate public; 2) provide a rationale that motivates individuals of diverse backgrounds to become scientifically literate; 3) consider the impact of personal perspective, e.g. values, beliefs, attitudes, etc., on learning; and 4) offer a relevant and manageable framework in which to define scientific literacy. For instance, past calls for improving scientific literacy, e.g. the U.S. is behind the Soviets in the space race, U.S students rank below country X in math and science, etc., have lacked justification, personal motivation and a comprehensive framework for defining scientific literacy. In these cases, the primary justification for improving science education and scientific literacy was to regain international dominance in the space race or to advance global standing according to test results. These types of calls also articulate short-term goals that are rendered moot once they have been achieved. At the same time, teaching practices have commonly failed to consider the perspectives students bring to the classroom. Many STEM faculty do not address issues of personal perspective through ignorance or the desire to avoid controversial subjects, e g. evolution, climate change. We propose that the ‘grand challenges’ (e.g., energy, climate change, antibacterial resistance, water, etc.) humankind currently faces provides a compelling framework for developing courses and curricula well-suited for improving scientific literacy. A grand challenge paradigm offers four

    2016-12-01

    We describe the mid-Miocene to present opening history of the Rio Grande rift from tectonic subsidence patterns, published Quaternary fault activity, and spatial, temporal and geochemical distributions of volcanism. Rift opening was quite fast until 8 Ma, with tectonic subsidence rates comparable to those of the pre-rupture phase of rifted continent margins, but post-8 Ma rates are slower in all studied localities. Integration of age control reveals that a rift-margin unconformity formed between 8.5 and 3.5 Ma, its exact duration varying depending on location. This partly coincides with uplift of the Ogallala formation in the western Great Plains. The widespread extent of the unconformity suggest that the unconformity records a region-wide dynamic uplift event, possibly resulting from mantle upwelling below the region. This is supported by geoid analyses. The unconformity postdates a change in relative plate motion between the North American and Pacific plates, which may account for the post-8 Ma decrease in subsidence rates. Distribution of Quaternary fault activity is concentrated on the border faults in the northern basins where the rift is in a juvenile stage, but distributed on intra-basin faults further south in the rift where the crust is thinned more. Our analyses show that volcanism in the Rio Grande rift has been of mainly basaltic composition since the Miocene; volcanism during early rifting ranged from basalt to rhyolite. Volcanism has not been evenly distributed in the rift, but concentrated in three large volcanic fields that were located outside of the main rift prior to rift opening, and along the Jemez Lineament which crosses the Rio Grande rift, with sporadic volcanic activity elsewhere. The southern portion of the rift has experienced less volcanic activity than the northern rift, perhaps because it is underlain by fast seismic wave velocity upper mantle that may be linked to colder or compositionally different (Farallon plate subduction related

    We offer an educational innovation called Ethical Grand Rounds (EGR) as a teaching strategy to enhance ethical decision-making. Nursing students participate in EGR-flexible ethical laboratories, where they take stands on ethical dilemmas, arguing for--or against--an ethical principle. This process provides the opportunity to move past normative ethics, that is, an ideal ethical stance in accord with ethical conduct codes, to applied ethics, what professional nurses would do in actual clinical practice, given the constraints that exist in contemporary care settings. EGR serves as a vehicle to translate "what ought to be" into "what is."

    Potential sources of pollutants can be identified by analyzing back trajectories associated with extreme ambient concentrations. Conditional frequency analysis (CFA) was used to identify statistically significant associations of geographical regions and ambient air quality observed at sites near the Grand Canyon. Stratification by season reveals a pattern of association during the fall quarter that is not observed during other seasons. Application of CFA to different source tracers provides additional information on the nature of the associations. Tracer species that were often below detection limits can be studied because the method requires only that the highest concentrations be identified.

    On July 1, 1984 the Bonneville Power Administration and the Oregon Department of Fish and Wildlife entered into an agreement to initiate fish habitat enhancement work in the Joseph Creek subbasin of the Grande Ronde River Basin in northeast Oregon. In July of 1985 the Upper and Middle Grande Ronde River, and Catherine Creek subbasins were included in the intergovernmental contract, and on March 1, 1996 the Wallowa River subbasin was added. The primary goal of ''The Grande Ronde Basin Fish Habitat Enhancement Project'' is to access, create, improve, protect, and restore riparian and instream habitat for anadromous salmonids, thereby maximizing opportunities for natural fish production within the basin. This project provided for implementation of Program Measure 703 (C)(1), Action Item 4.2 of the Northwest Power Planning Council's Columbia River Basin Fish and Wildlife Program (NPPC, 1987), and continues to be implemented as offsite mitigation for mainstem fishery losses caused by the Columbia River hydro-electric system. All work conducted by the Oregon Department of Fish and Wildlife is on private lands and therefore requires that considerable time be spent developing rapport with landowners to gain acceptance of, and continued cooperation with this program throughout 10-15 year lease periods. This project calls for passive regeneration of habitat, using riparian enclosure fencing as the primary method to restore degraded streams to a normative condition. Active remediation techniques using plantings, off-site water developments, site-specific instream structures, or whole channel alterations are also utilized where applicable. Individual projects contribute to and complement ecosystem and basin-wide watershed restoration efforts that are underway by state, federal, and tribal agencies, and local watershed councils. Work undertaken during 2000 included: (1) Implementing 2 new projects in the Grande Ronde drainage, and retrofitting one old

    Core activities of the Grande Ronde Endemic Spring Chinook Supplementation Program (GRESCSP) are funded through the authority of the Lower Snake River Fish and Wildlife Compensation Plan (LSRCP). The LSRCP program was approved by the Water Resources Development Act of 1976, PL 94-587, Section 102, 94th Congress substantially in accordance with the Special Report, LSRCP, June 1975 on file with the Chief of Engineers. The LSRCP was prepared and submitted in compliance with the Fish and Wildlife Coordination Act of 1958, PL 85-624, 85th Congress, August 12, 1958 to mitigate for the losses of fish and wildlife caused by the construction of dams on lower Snake River. The GRESCSP is an artificial propagation program that was initiated by Bonneville Power Administrations Fish and Wildlife program in the mid 1990's. The intent of this program was to change the mitigation aspect of the LSRCP program (harvest mitigation) to an integrated supplementation program; inasmuch as, hatchery produced fish could be experimentally used as a recovery tool and fish surplus to mitigation would be available for in-place and in-kind harvest. Fish production is still authorized by the LSRCP with the original mitigation return goal of 5,860 adult spring Chinook to the project area. The GRESCSP was developed with two primary components: (1) conventional broodstock (projects 199800702; 199800703; 199800704) and (2) captive brood (projects 199801001; 199801006). The GRESCSP relies on cooperative M&E efforts from the LSRCP including setting aside the Wenaha and Minam tributaries as natural production reserves components used for reference streams. The GRESCSP, coordinated with federal and tribal partners, identifies production levels for both propagation components and weir management strategies for each of the three supplemented tributary areas within the Grande Ronde Sub-basin. The three supplemented areas are Catherine Creek, Lostine River, and upper Grande Ronde River. Lookingglass

    The vast majority of vaccines used throughout the world are supplied by the private sector. It is essential therefore that the industry is closely engaged in future policy developments at a national and international level and is able to respond to the changing needs and priorities that may be required to ensure the success of Mission Grand Convergence. Uniquely, the major vaccine companies have the expertise and technical capacity to develop, produce and supply vaccines on a global scale. Through partnering with Governments, charities and NGOs, they must play a pivotal role in the Mission and, at the same time as agreeing on objectives that may not be entirely market driven, must be able to sustain their commercial obligations to shareholders. Similarly, small and medium sized companies, with the global investor market and government incentives that underpin and support them, also have a very important role to play; for example in innovation around a given disease and on technology, process and platform development across the whole value chain. The industry at large is therefore an essential player. Indeed Mission Grand Convergence can only succeed with the full and willing participation of the vaccines industry.

    2006-06-09

    In the first part of the talk, I explain what empirical evidence points to the need for having an effective grand unification-like symmetry possessing the symmetry SU(4)-color in 4D. If one assumes the premises of a future predictive theory including gravity--be it string/M theory or a reincarnation--this evidence then suggests that such a theory should lead to an effective grand unification-like symmetry as above in 4D, near the string-GUT-scale, rather than the standard model symmetry. Advantages of an effective supersymmetric G(224) = SU(2){sub L} x SU(2){sub R} x SU(4){sup c} or SO(10) symmetry in 4D in explaining (1) observed neutrino oscillations, (2) baryogenesis via leptogenesis, and (3) certain fermion mass-relations are noted. And certain distinguishing tests of a SUSY G(224) or SO(10)-framework involving CP and flavor violations (as in {mu} {yields} e{gamma}, {tau} {yields} {mu}{gamma}, edm's of the neutron and the electron) as well as proton decay are briefly mentioned. Recalling some of the successes we have had in our understanding of nature so far, and the current difficulties of string/M theory as regards the large multiplicity of string vacua, some comments are made on the traditional goal of understanding vis a vis the recently evolved view of landscape and anthropism.

  12. Geomorphology of plutonium in the Northern Rio Grande

    Nearly all of the plutonium in the natural environment of the Northern Rio Grande is associated with soils and sediment, and river processes account for most of the mobility of these materials. A composite regional budget for plutonium based on multi-decadal averages for sediment and plutonium movement shows that 90 percent of the plutonium moving into the system is from atmospheric fallout. The remaining 10 percent is from releases at Los Alamos. Annual variation in plutonium flux and storage exceeds 100 percent. The contribution to the plutonium budget from Los Alamos is associated with relatively coarse sediment which often behaves as bedload in the Rio Grande. Infusion of these materials into the main stream were largest in 1951, 1952, 1957, and 1968. Because of the schedule of delivery of plutonium to Los Alamos for experimentation and weapons manufacturing, the latter two years are probably the most important. Although the Los Alamos contribution to the entire plutonium budget was relatively small, in these four critical years it constituted 71--86 percent of the plutonium in bedload immediately downstream from Otowi.

    Full Text Available Os grandes eventos se globalizam na mesma medida em que proliferam os lugares promovidos como marcas. Embora autônomos, esses processos estão relacionados ao se fundarem numa visão de que os lugares devem competir na globalização e que a competição deve se dar a partir de suas imagens. Esse tipo de competição se embasa num discurso produzido por publicitários de marketing de lugar, que tanto manuseiam formas simbólicas construídas como identidades coletivas, quanto se engajam na produção de novos elementos, de forma a configurá-los, tal qual as marcas de produtos, como diferencial competitivo. Neste artigo, investigo a atuação desses publicitários, compreendidos como artífices de um “senso comum planetário” que ressignifica a imagem do lugar a partir de concepção de uma marca. Serão aqui analisados os pressupostos desse discurso, suas instâncias de legitimidade e sua relação com os grandes eventos, que devem ser entendidos como espaços de consagração e circulação do discurso do marketing de lugar.

    2011-12-01

    The "Seismological Grand Challenges in Understanding Earth's Dynamic Systems," a community-written long-range science plan for the next decade, poses 10 questions to guide fundamental seismological research. Written in an approachable fashion suitable for policymakers, the broad questions and supporting discussion contained in this document offer an ideal framework for the development of undergraduate curricular materials. Leveraging this document, we have created a collection of inquiry-based classroom modules that utilize authentic data to modernize seismological instruction in 100 and 200 level undergraduate courses. The modules not only introduce undergraduates to the broad questions that the seismological community seeks to answer in the future but also showcase the numerous areas where modern seismological research is actively contributing to our understanding of fundamental Earth processes. To date 6 in-depth explorations that correspond to the Grand Challenges document have been developed. The specific topics for each exploration were selected to showcase modern seismological research while also covering topics commonly included in the curriculum of these introductory classes. Examples of activities that have been created and their corresponding Grand Challenge include: -A guided inquiry that introduces students to episodic tremor and slip and compares the GPS and seismic signatures of ETS with those produced from standard tectonic earthquakes (Grand Challenge "How do faults slip?"). - A laboratory exercise where students engage in b-value mapping of volcanic earthquakes to assess potential eruption hazards (How do magmas ascend and erupt?). - A module that introduce students to glacial earthquakes in Greenland and compares their frequency and spatial distribution to tectonic earthquakes (How do processes in the ocean and atmosphere interact with the solid Earth?). What is the relationship between stress and strain in the lithosphere? - An activity that

  18. Is it possible to give scientific solutions to Grand Challenges? On the idea of grand challenges for life science research.

    Science.gov (United States)

    Efstathiou, Sophia

    2016-04-01

    This paper argues that challenges that are grand in scope such as "lifelong health and wellbeing", "climate action", or "food security" cannot be addressed through scientific research only. Indeed scientific research could inhibit addressing such challenges if scientific analysis constrains the multiple possible understandings of these challenges into already available scientific categories and concepts without translating between these and everyday concerns. This argument builds on work in philosophy of science and race to postulate a process through which non-scientific notions become part of science. My aim is to make this process available to scrutiny: what I call founding everyday ideas in science is both culturally and epistemologically conditioned. Founding transforms a common idea into one or more scientifically relevant ones, which can be articulated into descriptively thicker and evaluatively deflated terms and enable operationalisation and measurement. The risk of founding however is that it can invisibilise or exclude from realms of scientific scrutiny interpretations that are deemed irrelevant, uninteresting or nonsensical in the domain in question-but which may remain salient for addressing grand-in-scope challenges. The paper considers concepts of "wellbeing" in development economics versus in gerontology to illustrate this process. Copyright © 2015 Elsevier Ltd. All rights reserved.

  19. The Grand Ethiopian Renaissance Dam: Source of cooperation or contention?

    Science.gov (United States)

    Teferi Taye, Meron; Tadesse, Tsegaye; Senay, Gabriel; Block, Paul

    2016-01-01

    This paper discusses the challenges and benefits of the Grand Ethiopian Renaissance Dam (GERD), which is under construction and expected to be operational on the Blue Nile River in Ethiopia in a few years. Like many large-scale projects on transboundary rivers, the GERD has been criticized for potentially jeopardizing downstream water security and livelihoods through upstream unilateral decision making. In spite of the contentious nature of the project, the authors argue that this project can provide substantial benefits for regional development. The GERD, like any major river infrastructure project, will undeniably bring about social, environmental, and economic change, and in this unique case has, on balance, the potential to achieve success on all fronts. It must be stressed, however, that strong partnerships between riparian countries are essential. National success is contingent on regional cooperation.

  20. Climate Change Impacts in the Upper Rio Grande Catchment

    2010-12-01

    In the US Southwest, evidence of increased future drought severity and duration in the context of climate change has been detected. Considering the already difficult water distribution and allocation strategies within the region, we are investigating the Costilla Creek, a tributary to the Rio Grande. The catchment is located in Costilla county in Colorado from where on runoff is crossing boundaries between Colorado and New Mexico three times before its confluence with the Rio Grande in New Mexico. Water allocation is governed by an interstate compact between Colorado and New Mexico. While the states have been relatively successful in complying with the compact’s allocation rules, the Costilla Creek catchment has experienced interstate upstream/downstream conflict, mainly during irrigation seasons. Whether or not the states will be able to avert conflict in the future and maintain compliance with the compact, is a critical question. The situation in the relatively small catchment is not unique. Various interstate watersheds, including the entire Rio Grande basin, the La Plata, Arkansas, and Colorado, are expected to face similar impacts from climate change, yet the water compacts that govern them may not be structured to adapt to these conditions. Looking at the Costilla Creek offers a valuable starting point for understanding how to model these effects across various basins. We have developed a lumped-parameter rainfall-runoff model including snow storage of the Costilla Creek watershed. Temperature and precipitation data from NCRS - SNOTEL stations together with USGS gauging station data were utilized for model calibration and validation. ISCCP solar radiation data and temperature data were used to estimate irrigation water demand in irrigated agriculture. The model is driven by the IPCC SRES A2 scenario. GCM ensemble averaged temperature / precipitation trends were extracted for the upper Rio Grande region. 50 year precipitation simulations were created using a

    We have worked with elementary and middle school teachers in the Rio Grande Valley for the last 10 years bringing Earth and Space Science themed workshops to underserved areas of Texas. The Texas curriculum was also changed to include Astronomy and Space Science requirement in the tests students need to take to prove their academic preparedness. The teachers worked through a variety of inquiry-based, hands-on activities after a short presentation on the background science. In order to evaluate our effectiveness, we have asked the teachers to take pre- and post-workshop tests, and we asked them to fill out a self-reflective survey. We will report on our experiences, what works best with the teachers, and in what areas we still have a long way to go.This work was supported by various NASA education grants and Cooperative agreements, as well as grants provided by the Texas Space Grant Consortium.

    Full Text Available Insects of the Simuliidae family have been the object of control in Rio Grande do Sul since the 70s. Their constant attacks became a social-economical problem as well as a problem of Public Health, with serious consequences to men and to the economy of the areas in which the insects develop. At first, the control was done with a chemical larvicide Themephos ABATE 500 E, but an imperfect measuring of outflow to determine the quantity of the product made Simulium spp. resistant to it. From 1983 on, following a study of a new method for the outflow measuring, we started to use a biological larvicide Bacillus thuringiensis serovar israelensis based. The biological control uses the new method in 36.4% of the state area, assisting about 3,500,000 inhabitants.

    On July 1, 1984 the Bonneville Power Administration and the Oregon Department of Fish and Wildlife entered into an intergovernmental contract to initiate fish habitat enhancement work in the Joseph Creek subbasin of the Grande Ronde River Basin in northeast Oregon. In 1985 the Upper and Middle Grande Ronde River, and Catherine Creek subbasins were included in the contract, and in 1996 the Wallowa River subbasin was added. The primary goal of 'The Grande Ronde Basin Fish Habitat Enhancement Project' is to create, protect, and restore riparian and instream habitat for anadromous salmonids, thereby maximizing opportunities for natural fish production within the basin. This project provided for implementation of Program Measure 703 (C)(1), Action Item 4.2 of the Northwest Power Planning Council's Columbia River Basin Fish and Wildlife Program (NPPC, 1987), and continues to be implemented as offsite mitigation for mainstem fishery losses caused by the Columbia River hydro-electric system. All work conducted by the Oregon Department of Fish and Wildlife and partners is on private lands and therefore requires that considerable time be spent developing rapport with landowners to gain acceptance of, and continued cooperation with this program throughout 10-15 year lease periods. Both passive and active restoration treatment techniques are used. Passive regeneration of habitat, using riparian exclosure fencing and alternate water sources are the primary method to restore degraded streams when restoration can be achieved primarily through changes in management. Active restoration techniques using plantings, bioengineering, site-specific instream structures, or whole stream channel alterations are utilized when streams are more severely degraded and not likely to recover in a reasonable timeframe. Individual projects contribute to and complement ecosystem and basin-wide watershed restoration efforts that are underway by state, federal, and tribal agencies, and

    Earth science educators need interactive tools to engage and enable students to better understand how Earth systems work over geologic time scales. The evolution of landforms is ripe for interactive, inquiry-based learning exercises because landforms exist all around us. The Web-based Interactive Landform Simulation Model - Grand Canyon (WILSIM-GC, http://serc.carleton.edu/landform/) is a continuation and upgrade of the simple cellular automata (CA) rule-based model (WILSIM-CA, http://www.niu.edu/landform/) that can be accessed from anywhere with an Internet connection. Major improvements in WILSIM-GC include adopting a physically based model and the latest Java technology. The physically based model is incorporated to illustrate the fluvial processes involved in land-sculpting pertaining to the development and evolution of one of the most famous landforms on Earth: the Grand Canyon. It is hoped that this focus on a famous and specific landscape will attract greater student interest and provide opportunities for students to learn not only how different processes interact to form the landform we observe today, but also how models and data are used together to enhance our understanding of the processes involved. The latest development in Java technology (such as Java OpenGL for access to ubiquitous fast graphics hardware, Trusted Applet for file input and output, and multithreaded ability to take advantage of modern multi-core CPUs) are incorporated into building WILSIM-GC and active, standards-aligned curricula materials guided by educational psychology theory on science learning will be developed to accompany the model.

    Full Text Available Desde a revolução industrial que inaugurou, no campo da comunicação, a era da reprodutibilidade técnica, novas tecnologias midiáticas não cessam de emergir em um ritmo cada vez mais intenso até se tornar verdadeiramente avassalador a partir do advento do universo digital. Essa emergência crescente de tecnologias midiáticas não é um fenômeno isolado, mas deve ser inserida no contexto bem mais amplo daquilo que os especialistas em mudanças climáticas e geologia estão chamando de “grande aceleração”. Para realizar tal inserção, este artigo tomou como roteiro metodológico o levantamento e estudo de dados bibliográficos, de um lado, relativos à evolução midiática desde a revolução industrial no século XIX até os nossos dias. De outro lado, relativos ao crescimento desmedido do gasto de fontes energéticas do planeta inteiramente imerso na circulação perversa do mercado capitalista. A comparação entre os dados tanto de um quanto de outro lado, conduziu esta pesquisa à constatação de uma interrelação indissolúvel entre ambos. Esse percurso nos leva à conclusão de que a aceleração midiática é parte integrante e contribui a seu modo para a grande aceleração que está levando o planeta Terra a uma nova era geológica.

    Full Text Available For more than two millennia, the historic Grand Trunk Road, the busy thoroughfare that extends some 1500 miles through north India and Pakistan served as the main artery of South Asia. It was also the gateway through which waves of immigrants, travelers, and invaders entered the subcontinent. As a result, a great deal of diversity and tolerance marks the road. Between 1988 and 1991, Raghubir Singh (1942-1999, one of India’s renowned documentary photographers, traveled and photographed the Indian stretch of the Road. Ninety-six photographs from his journeys appear in the publication, 'The Grand Trunk Road: A Passage Through India '(1995. Singh used the pictorial style of street photography that he is known for to capture everyday life along the path. Further, he emphasized the tremendous diversity he witnessed along the road through the selections he made for inclusion in the book and the specific manner in which he arranged many of them. By underscoring the heterogeneity, Singh provided a critical visual commentary of the political climate in India during the 1980s and early nineties. This period coincided with the rise of Hindu nationalism, which aimed to erase the subcontinent’s diverse past and promote instead the idea of a homogenous/Hindu India. By documenting the road in his uniquely pictorial style and arranging the photographs in his book to draw attention to the differences and tolerance witnessed along the path, Singh demonstrated that India was not a monolithic culture as the politics of the time claimed, but a rich interwoven fabric of many varied strands.

    Yuntai/Grand Canyon is a result of long-term historical evolution and a rare natural heritage of the world. With its rich heritages of geological physiognomy, systematic geological record, abundant biological fossil combination, long history of structural evolution, they are of contrastive research values worldwide. The Grand Canyon was declared national natural heritage on eleventh January, and in 1979 it was entitled World Natural Heritage Site. Though the two major sites are separated by tremendous seas, they reached agreements in the protection of natural heritages worldwide on account of the shared ideas of society, demonstrating to our children how can we protect the two scenery sites. Keyword:Geopark, Geoheritage, Yuntai Landform, GrandCanyon Mt. Taihang rises from the central part of north China and extends to the west edge of North China Plain. Towering, and with ragged peaks, precarious cliffs, long strips of walls, deep valleys and shaded streams, Mt. Taihang poses impressive sights with its clear water, dense forest and wonderful sceneries. It is indeed the east slope of Qin-Jin Plateau. Indeed things tend to coincide. On the other side of the Pacific Ocean, along the west edge of north America and on the wide and spacious Colorado Plateau, there is a winding and deep valley where there are layers of rocks, extensive sharp cliffs, intercrossing ravines and forests of peaks; it is totally impressive. Both sceneries are known to the world for their beauty. Identical geological conditions and similar history of evolution left two natural sights that resemble each other so much. Geological changes are infinite, and sedimentation works in similar ways on both sights; and the changing ecological environment gives the world two colorful and comparable geological records. Both sights are merely brief periods in the long history of earth development, but they show us how cradles of human proliferation and social civilization had looked. 1,Comparison of two parks

    2013-06-01

    Full Text Available Este artigo analisa uma abordagem de Sociologia Política Internacional (SPI inspirada em uma metodologia relacional e processual que questiona as premissas das RI quanto às fronteiras do internacional, a visão de que a política está no centro das ciências políticas e o nacionalismo metodológico no que diz respeito à sociedade. A fim de evitar dualismos, a SPI discute as diferentes epistemes em jogo e analisa a sociogênese das práticas dos atores em seus distintos universos profissionais e culturais, com atenção especial para as disputas por poder entre esses atores e para os processos de politização e (insecuritização. A SPI é, portanto, construtivista na medida em que seus autores são reflexivos e desconstroem reivindicações de conhecimento essencialistas. A SPI é também empiricista na medida em que seus autores são sensíveis às práticas dos seres humanos e a suas relações com objetos. Nessa abordagem, as teorias partem dessas relações sociológicas e históricas, sempre incrustadas em locais e tempos específicos. Logicamente, o empiricismo não significa positivismo, e o construtivismo não significa uma perspectiva idealista em que normas, ideias e crenças lideram o mundo. Dessa forma, a SPI também constitui um esforço de descolonizar o estudo das práticas das "sociedades transnacionais de indivíduos" dos chamados "grandes debates" das visões anglo-americanas, reproduzidos transversalmente em suas filosofias e abordagens de ciências sociais.

    Full Text Available Resumo ----- O turismo tem sido entendido por organismos internacionais como atividade com grande potencial para promover o desenvolvimento econômico e, ao mesmo tempo, que valoriza a cultura e promove a preservação das paisagens naturais. Seguindo as diretrizes internacionais, no Brasil, o turismo passou a ser entendido como uma indústria com grande potencial para gerar empregos e divisas, e se fortalece por meio da promoção da diversidade cultural, que pode estar associada às diversas culturas materiais e religiosas. Para compreender a gestão do turismo em contextos que articulam cultura, religião e desenvolvimento territorial, este ensaio teórico aponta limitações nos dois conceitos disponíveis na literatura, quais sejam, o conceito de turismo cultural e o conceito de turismo religioso, ao mesmo tempo que propõe o conceito de ‘turismo em territórios de grande densidade religiosa’, o qual incorpora o reconhecimento das dinâmicas de poder presentes nos territórios como elementos que interferem na forma como se planeja o turismo. Mobilizam-se entendimentos do campo da antropologia e da geografi a para a gestão a fim de sustentar que a discussão teórica conduzida tem um potencial explicativo para o turismo em diversas escalas territoriais, e, também, em contextos nos quais existe o diálogo entre turismo e religião. ----- Tourism in Territories of High Religious Density ----- Abstract ----- Tourism has been understood by international organizations as an activity with great potential to promote economic development, while valuing cultures and promoting the protection of natural landscapes.

  2. Particle physics models of inflation in supergravity and grand unification

    Energy Technology Data Exchange (ETDEWEB)

    Kostka, Philipp Manuel

    2010-12-03

    In the first part of this thesis, we study classes of hybrid and chaotic inflation models in four-dimensional N=1 supergravity. Therein, the {eta}-problem can be resolved relying on fundamental symmetries in the Kaehler potential. Concretely, we investigate explicit realizations of superpotentials, in which the flatness of the inflaton potential is protected at tree level by a shift symmetry or a Heisenberg symmetry in the Kaehler potential. In the latter case, the associated modulus field can be stabilized during inflation by supergravity effects. In the context of hybrid inflation, a novel class of models, to which we refer as ''tribrid inflation,'' turns out to be particularly compatible with such symmetry solutions to the {eta}-problem. Radiative corrections due to operators in the superpotential, which break the respective symmetry, generate the required small slope of the inflaton potential. Additional effective operators in the Kaehler potential can reduce the predicted spectral index so that it agrees with latest observational data. Within a model of chaotic inflation in supergravity with a quadratic potential, we apply the Heisenberg symmetry to allow for viable inflation with super-Planckian field values, while the associated modulus is stabilized. We show that radiative corrections are negligible in this context. In the second part, the tribrid inflation models are extended to realize gauge non-singlet inflation. This is applied to the matter sector of supersymmetric Grand Unified Theories based on the Pati-Salam gauge group. For the specific scenario in which the right-handed sneutrino is the inflaton, we study the scalar potential in a D-flat valley. We show that despite potentially dangerous two-loop corrections, the required flatness of the potential can be maintained. The reason for this is the strong suppression of gauge interactions of the inflaton field due to its symmetry breaking vacuum expectation value. In addition, the

Control points are integral for geo-referencing the myriad of data collected in the Grand Canyon including aerial photography, topographic and bathymetric data used for classification and change-detection analysis of physical, biologic and cultural resources. The survey department has compiled a list of 870 control points installed by various organizations needing to establish a consistent reference for data collected at field sites along the 240 mile stretch of Colorado River in the Grand Canyon. This list is the foundation for the Control Point Database established primarily for researchers, to locate control points and independently geo-reference collected field data. The database has the potential to be a valuable mapping tool for assisting researchers to easily locate a control point and reduce the occurrance of unknowingly installing new control points within close proximity of an existing control point. The database is missing photographs and accurate site description information. Current site descriptions do not accurately define the location of the point but refer to the project that used the point, or some other interesting fact associated with the point. The Grand Canyon Monitoring and Research Center (GCMRC) resolved this problem by turning the data collection effort into an educational exercise for the participants of the Grand Canyon Youth organization. Grand Canyon Youth is a non-profit organization providing experiential education for middle and high school aged youth. GCMRC and the Grand Canyon Youth formed a partnership where GCMRC provided the logistical support, equipment, and training to conduct the field work, and the Grand Canyon Youth provided the time and personnel to complete the field work.

    seguimento foi 3,4 anos. RESULTADOS: Todas as queixas devido a varizes foram resolvidas em todos os pacientes. Algumas complicações temporárias observadas foram resolvidas totalmente durante o tempo de seguimento. Parestesia permanente que foi a complicação mais grave ocorreu apenas em dois pacientes (2%. Não observamos recurrência. CONCLUSÃO: O risco da lesão do nervo safeno no tornozelo não deve ser considerada uma razão para evitar-se a fleboextração completa da VSM até o tornozelo. Se é aplicada cuidadosamente e com a técnica apropriada, fleboextração ainda parece ser uma boa opção de tratamento.

Luego de los estudios correspondientes, se permitió hacer el diagnóstico de transposición corregida de grandes vasos. La paciente tenía asociada una anomalía de Ebstein, comunicación interauricular, una comunicación interventricular, y una persistencia del conducto arterioso, todo lo cual agravaba su cuadro clínico. Primero es intervenida quirúrgicamente, y se cierra el ducto; de manera espontánea, cierra la comunicación interauricular, y la anomalía de Ebstein parchea la comunicación interventricular. La niña desarrolla una insuficiencia cardiaca e hipertensión pulmonar, a consecuencia de las anomalías asociadas. El caso es de interés, ya que son pocos los publicados en la literatura internacional con esta cardiopatía congénita asociada a otras anomalías estructurales del corazón, que modifican su historia natural.

  12. The Grand Canyon midair collision. A stimulus for change.

    Commercial aviation in the United States developed rapidly from a nucleus of pilots who returned from World War I, barnstormed and flew primitive airmail routes, and were hired by the new commerical airlines of the 1930s. The death of U.S. Senator Bronson Cutting in a 1935 crash was an important stimulus to improved governmental regulation of civil aviation. The air traffic control system, primitive until and throughout World War II, was soon proven to be inadequate for postwar demands. The midair collision of two large airliners over the Grand Canyon in June 1956 that killed the 128 persons on board was itself a strong stimulus for serious efforts, particularly in improving air traffic control systems. This and many other difficult problems in aviation safety have been addressed in the subsequent 33 years, some with success, although it has not always been immediate, and with major accidents still occurring. Commercial air travel is safe and widely accepted, however, and there is promise for additional important advances here.

    Full Text Available Salmonella spp. was the major cause of reported foodborne diseases in the last years in the State of Rio Grande do Sul, South of Brazil. Epidemiological data on salmonellosis, occurred in the period of 1997 to 1999 and supplied by the Division of Sanitary Surveillance (DVS/RS, were analysed according to the following factors: total number of confirmed outbreaks, number of people involved, outbreaks incidence according to the period of the year, age and sex of involved people, food vehicle, food storage conditions, local where the disease occurred, and possible causes of the outbreaks. The results indicated that 8217 people were involved, and 1557 had to be hospitalized. The highest number of outbreaks occurred during springtime and the principal age group affected was between 16 and 50 years. The most common food vehicle was salad prepared with homemade mayonnaise (42.45%. The principal causes of salmonellosis were raw-materials not submitted to regulatory inspection (22.92%, mainly eggs, and foods maintained at room temperature for more than 2 hours (20.55%. The majority of the outbreaks occurred in private homes (43.70% and commercial food establishments (25.21%.

    The Cassini Grand Finale Mission, which consists of 22 ballistic orbits, will begin on April 22, 2017 after the last targeted Titan flyby. It will end on September 15, 2017 when the spacecraft dives into Saturn's atmosphere and be permanently captured. High volumes of unique science data from various onboard instruments are expected from the mission. To ensure its success and facilitate science planning, the trajectory dispersion needs to be controlled below 250 km (root-mean-square spatial deviation at the 68th percentile level) for a few segments of trajectory in the mission. This paper reports the formulation and solution of this dispersion control problem. We consider various sources of uncertainties including flyby error, orbit determination error, maneuver execution error, thruster firing control error, and uncertainty in Saturn's atmospheric model. A non-linear Monte Carlo Trajectory Dispersion tool is developed and employed for the analysis. It is found that a total of three Orbit Trim Maneuvers with a 99% (Delta)V usage of less than 2 m/s will adequately control the trajectory.

    The KASCADE-Grande experiment operated at KIT from January 2004 to November 2012, measuring EAS generated by primary cosmic rays in the 10{sup 16}–10{sup 18} eV energy range. The experiment detected, for each single event, with a high resolution, the total number of charged particles (N{sub ch}) and of muons (N{sub μ}). In this contribution we present the latest results about: (i)The measurement of the all particle energy spectrum, discussing the influence of the hadronic interaction model used to derive the energy calibration of the experimental data. (ii)The energy spectra derived separating the events according to the N{sub μ}/N{sub ch} ratio. This technique allowed us to unveil a steepening of the spectrum of heavy primaries at E∼10{sup 16.92±0.04}eV and a hardening of the spectrum of light primaries at E∼10{sup 17.08±0.08}eV. (iii)The elemental spectra (for five mass groups) obtained applying a detailed unfolding analysis technique. (iv)A search for large scale anisotropies.

    By late 2000, Petro-Canada will be reborn with 60,000 barrels a day from the prolific geology 300 kilometers out to sea on the Grand Banks known as the Jeanne d`Arc Basin. It will get 27,000 from its 20% share in 135,000 barrels daily from Hibernia, plus 33,000 from its 29% senior share as operator of the next big development, 115,000 barrels daily from Terra Nova. While offshore wells cost $25-$40 million each, it has taken only 48 of them to find 1.6 billion barrels of reserves in the Jeanne d`Arc including the fourth- and seventh-biggest oil pools ever found in Canada. Although Terra Nova`s daily production will be 85% of Hibernia`s rate, the second project`s $2 billion pricetag is only 34% of the first one`s $5.8 billion. Terra Nova will be three and a half years coming into production and $2 billion in cost.

  19. Grand minima of solar activity and sociodynamics of culture

    Indices of creative productivity introduced by C. Murrey were used to verify S. Ertel's conclusion about a global increase in creative productivity during the prolonged minimum of solar activity in 1640-1710. It was found that these indices for mathematicians, philosophers, and scientists increase in the Maunder era by factor of 1.6 in comparison with intervals of the same length before and after the minimum. A similar effect was obtained for mathematicians and philosophers for five earlier equitype minima in total (an increase by a factor of 1.9). The regularity that is revealed is confirmed by the fact that the most important achievements of high-ranking mathematicians and philosophers during the whole time period (2300 years) considered in this study fall on epochs of reduced levels of solar activity. The rise in the probability of the generation of rational ideas during grand minima is reflected also in the fact that they precede the appearance of written language and farming. Ultra-low-frequency electromagnetic fields appear to serve as a physical agent stimulating the activity of the brain's left hemisphere during the epochs of minima.

  20. Hiker Fatality From Severe Hyponatremia in Grand Canyon National Park.

    We present the case of a hiker who died of severe hyponatremia at Grand Canyon National Park. The woman collapsed on the rim shortly after finishing a 5-hour hike into the Canyon during which she was reported to have consumed large quantities of water. First responders transported her to the nearest hospital. En route, she became unresponsive, and subsequent treatment included intravenous normal saline. Imaging and laboratory data at the hospital confirmed hypervolemic hyponatremia with encephalopathy. She never regained consciousness and died of severe cerebral edema less than 24 hours later. We believe this is the first report of a fatality due to acute hyponatremia associated with hiking in a wilderness setting. This case demonstrates the typical pathophysiology, which includes overconsumption of fluids, and demonstrates the challenges of diagnosis and the importance of appropriate acute management. Current treatment guidelines indicate that symptomatic exercise-associated hyponatremia should be acutely managed with hypertonic saline and can be done so without concern over central pontine myelinolysis, whereas treatment with high volumes of isotonic fluids may delay recovery and has even resulted in deaths.

    Devising strategies for economic development in a globally competitive landscape requires a solid and unbiased understanding of countries' technological advancements and similarities among export products. Both can be addressed through the bipartite representation of the International Trade Network. In this paper, we apply the recently proposed grand canonical projection algorithm to uncover country and product communities. Contrary to past endeavors, our methodology, based on information theory, creates monopartite projections in an unbiased and analytically tractable way. Single links between countries or products represent statistically significant signals, which are not accounted for by null models such as the bipartite configuration model. We find stable country communities reflecting the socioeconomic distinction in developed, newly industrialized, and developing countries. Furthermore, we observe product clusters based on the aforementioned country groups. Our analysis reveals the existence of a complicated structure in the bipartite International Trade Network: apart from the diversification of export baskets from the most basic to the most exclusive products, we observe a statistically significant signal of an export specialization mechanism towards more sophisticated products.

    The Grand Challenges were launched in 2003 by the Gates Foundation and other collaborators to address the health needs of developing countries. This paper outlines the current problem with health research and development in the context of inequality as conveyed by the 90/10 divide. The paper then looks at the focus and nature of press reporting of global health issues by analysing how press articles have portrayed the Grand Challenges in Global Health initiative. Analysis of the mass media illustrates that the focus of reporting on the Grand Challenges tends to be on utilitarian themes, leaving issues related to justice and equity comparatively under-reported.

    This 1:24,000-scale geologic map of the Grand Junction 7.5' quadrangle, in support of the USGS Western Colorado I-70 Corridor Cooperative Geologic Mapping Project, provides new interpretations of the stratigraphy, structure, and geologic hazards in the area of the junction of the Colorado River and the Gunnison River. Bedrock strata include the Upper Cretaceous Mancos Shale through the Lower Jurassic Wingate Sandstone units. Below the Mancos Shale, which floors the Grand Valley, the Upper and Lower(?)Cretaceous Dakota Formation and the Lower Cretaceous Burro Canyon Formation hold up much of the resistant northeast- dipping monocline along the northeast side of the Uncompahgre uplift. The impressive sequence of Jurassic strata below include the Brushy Basin, Salt Wash, and Tidwell Members of the Upper Jurassic Morrison Formation, the Middle Jurassic Wanakah Formation and informal 'board beds' unit and Slick Rock Member of the Entrada Formation, and the Lower Jurassic Kayenta Formation and Wingate Sandstone. The Upper Triassic Chinle Formation and Early Proterozoic meta-igneous gneiss and migmatitic meta- sedimentary rocks, which are exposed in the Colorado National Monument quadrangle to the west, do not crop out here. The monoclinal dip slope of the northeastern margin of the Uncompahgre uplift is apparently a Laramide structural feature. Unlike the southwest-dipping, high-angle reverse faults in the Proterozoic basement and s-shaped fault- propagation folds in the overlying strata found in the Colorado National Monument 7.5' quadrangle along the front of the uplift to the west, the monocline in the map area is unbroken except at two localities. One locality displays a small asymmetrical graben that drops strata to the southwest. This faulted character of the structure dies out to the northwest into an asymmetric fault-propagation fold that also drops strata to the southwest. Probably both parts of this structure are underlain by a northeast-dipping high

    We demonstrate the viability of the one-loop neutrino mass mechanism within the framework of grand unification when the loop particles comprise scalar leptoquarks (LQs) and quarks of the matching electric charge. This mechanism can be implemented in both supersymmetric and non-supersymmetric models and requires the presence of at least one LQ pair. The appropriate pairs for the neutrino mass generation via the up-type and down-type quark loops are S{sub 3}-R{sub 2} and S{sub 1,3}-R{sub 2}, respectively. We consider two distinct regimes for the LQ masses in our analysis. The first regime calls for very heavy LQs in the loop. It can be naturally realized with the S{sub 1,3}-R{sub 2} scenarios when the LQ masses are roughly between 10{sup 12} and 5 x 10{sup 13} GeV. These lower and upper bounds originate from experimental limits on partial proton decay lifetimes and perturbativity constraints, respectively. Second regime corresponds to the collider accessible LQs in the neutrino mass loop. That option is viable for the S{sub 3}-R{sub 2} scenario in the models of unification that we discuss. If one furthermore assumes the presence of the type II see-saw mechanism there is an additional contribution from the S{sub 3}-R{sub 2} scenario that needs to be taken into account beside the type II see-saw contribution itself. We provide a complete list of renormalizable operators that yield necessary mixing of all aforementioned LQ pairs using the language of SU(5). We furthermore discuss several possible embeddings of this mechanism in SU(5) and SO(10) gauge groups. (orig.)

  13. Lunar and terrestrial planet formation in the Grand Tack scenario

    2014-01-01

    We present conclusions from a large number of N-body simulations of the giant impact phase of terrestrial planet formation. We focus on new results obtained from the recently proposed Grand Tack model, which couples the gas-driven migration of giant planets to the accretion of the terrestrial planets. The giant impact phase follows the oligarchic growth phase, which builds a bi-modal mass distribution within the disc of embryos and planetesimals. By varying the ratio of the total mass in the embryo population to the total mass in the planetesimal population and the mass of the individual embryos, we explore how different disc conditions control the final planets. The total mass ratio of embryos to planetesimals controls the timing of the last giant (Moon-forming) impact and its violence. The initial embryo mass sets the size of the lunar impactor and the growth rate of Mars. After comparing our simulated outcomes with the actual orbits of the terrestrial planets (angular momentum deficit, mass concentration) and taking into account independent geochemical constraints on the mass accreted by the Earth after the Moon-forming event and on the time scale for the growth of Mars, we conclude that the protoplanetary disc at the beginning of the giant impact phase must have had most of its mass in Mars-sized embryos and only a small fraction of the total disc mass in the planetesimal population. From this, we infer that the Moon-forming event occurred between approximately 60 and approximately 130 Myr after the formation of the first solids and was caused most likely by an object with a mass similar to that of Mars.

    Leach, D H; Ormrod, K; Clayton, H M

    1984-05-01

    An investigation was made of the stride characteristics of horses jumping 2 obstacles during a Grand Prix competition. One obstacle was a picket fence and rail 1.3 m high (fence 2), and the other was a coop and rail 1.52 m high (fence 11). Thirteen distance and 22 timing measurements of 17 horses were extracted from high-speed films, using computer-aided analysis. These data were used to compare takeoff and landing of the lead and nonlead legs, the thoracic limbs and pelvic limbs, and fence 2 and fence 11. Paired t-tests were used to compare means and a stepwise regression analysis was done for each fence, using the total horizontal distance jumped as the dependent variable. Stride timing and distance measurements did not differ (P less than 0.05) between the 2 fences . Each horse approached the fences in a moderately fast canter and, at takeoff , placed the nonlead thoracic limb earlier and farther from the fence than the lead thoracic limb (P less than 0.05). The nonlead leg stance phase lasted longer than the lead leg stance phase (P less than 0.05). The lead and nonlead pelvic limbs acted more in unison than the thoracic limbs and did not differ in their time of placement, stance phase duration, or position from the fence (P less than 0.05). The overlap of the stance phases of the pelvic limbs was greater than that of the thoracic limbs (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available El trabajo trata de revisar la literatura existente sobre la importancia de la localización para el desarrollo de las ciudades, poniéndola en relación con los salarios y la competitividad. Partiendo de los modelos clásicos, se repasan otros más actuales como los desarrollados por Krugman, Polèse o Florida, trabajos todos que asignan un papel relevante al territorio. Sin embargo, parece que la aglomeración y la ubicación no constituyen las únicas condiciones para el desarrollo económico y el aumento de la competitividad y la productividad. El progreso tecnológico y organizativo de las empresas se ha convertido en alternativa para la mejora de la competitividad, apareciendo otros factores como la especialización o la división espacial y territorial de la producción que estarían facilitando el ajuste de los costes de manera más eficiente. En última instancia, el artículo trata de responder a dos preguntas fundamentales: si se pagan mayores salarios ciudades grandes y si esto hace que pierdan competitividad las empresas allí ubicadas. El repaso de la bibliografía propuesta parece confirmar la existencia de una relación positiva entre ingresos elevados y aglomeración urbana, si bien responder a la segunda cuestión entraña una mayor dificultad, debido a las divergentes opiniones existentes en la literatura.

O resto do mundo, por sua vez, está adaptando suas estratégias diante da ascensão chinesa. Assim, a China encontra-se perante a necessidade de construir uma relação favorável com o exterior. É nesse contexto que o país avança uma estratégia de desenvolvimento pacífico e uma visão de mundo harmoniosa com o objetivo de assegurar a seus parceiros suas boas intenções. Nesse processo, a China valoriza a cooperação entre países emergentes, notadamente com os países BRICS. Comparado ao modelo desigual de interação do G8+5, os BRICS oferecem uma plataforma independente para potências emergentes trabalharem como um grupo no âmbito do atual sistema internacional. A China considera os países BRICS parceiros estratégicos para o desenvolvimento, pares com opiniões compartilhadas sobre os assuntos mundiais e novas forças em prol da reforma do sistema internacional. Conquanto aposte no futuro dos BRICS, permanece consciente das diferenças e cautelas existentes entre os membros. Como sua grande estratégia é de ascensão pacífica e construtiva, a China entende os BRICS como uma força internacional progressiva e cooperativa, e não como uma força coletiva de bloqueio.

  18. Towards a Grand Unified Theory of sports performance.

    Science.gov (United States)

    Glazier, Paul S

    2015-12-22

    Sports performance is generally considered to be governed by a range of interacting physiological, biomechanical, and psychological variables, amongst others. Despite sports performance being multi-factorial, however, the majority of performance-oriented sports science research has predominantly been monodisciplinary in nature, presumably due, at least in part, to the lack of a unifying theoretical framework required to integrate the various subdisciplines of sports science. In this target article, I propose a Grand Unified Theory (GUT) of sports performance-and, by elaboration, sports science-based around the constraints framework introduced originally by Newell (1986). A central tenet of this GUT is that, at both the intra- and inter-individual levels of analysis, patterns of coordination and control, which directly determine the performance outcome, emerge from the confluence of interacting organismic, environmental, and task constraints via the formation and self-organisation of coordinative structures. It is suggested that this GUT could be used to: foster interdisciplinary research collaborations; break down the silos that have developed in sports science and restore greater disciplinary balance to the field; promote a more holistic understanding of sports performance across all levels of analysis; increase explanatory power of applied research work; provide stronger rationale for data collection and variable selection; and direct the development of integrated performance monitoring technologies. This GUT could also provide a scientifically rigorous basis for integrating the subdisciplines of sports science in applied sports science support programmes adopted by high-performance agencies and national governing bodies for various individual and team sports.

  19. Leptoquark mechanism of neutrino masses within the grand unification framework

    Doršner, Ilja; Fajfer, Svjetlana; Košnik, Nejc

    2017-06-01

    We demonstrate the viability of the one-loop neutrino mass mechanism within the framework of grand unification when the loop particles comprise scalar leptoquarks (LQs) and quarks of the matching electric charge. This mechanism can be implemented in both supersymmetric and non-supersymmetric models and requires the presence of at least one LQ pair. The appropriate pairs for the neutrino mass generation via the up-type and down-type quark loops are S_3-R_2 and S_{1, 3}-\\tilde{R}_2, respectively. We consider two distinct regimes for the LQ masses in our analysis. The first regime calls for very heavy LQs in the loop. It can be naturally realized with the S_{1, 3}-\\tilde{R}_2 scenarios when the LQ masses are roughly between 10^{12} and 5 × 10^{13} GeV. These lower and upper bounds originate from experimental limits on partial proton decay lifetimes and perturbativity constraints, respectively. Second regime corresponds to the collider accessible LQs in the neutrino mass loop. That option is viable for the S_3-\\tilde{R}_2 scenario in the models of unification that we discuss. If one furthermore assumes the presence of the type II see-saw mechanism there is an additional contribution from the S_3-R_2 scenario that needs to be taken into account beside the type II see-saw contribution itself. We provide a complete list of renormalizable operators that yield necessary mixing of all aforementioned LQ pairs using the language of SU(5). We furthermore discuss several possible embeddings of this mechanism in SU(5) and SO(10) gauge groups.

    1994-10-01

    The so-called protein folding problem has numerous aspects, however it is principally concerned with the {ital de novo} prediction of three-dimensional (3D) structure from the protein primary amino acid sequence, and with the kinetics of the protein folding process. Our current project focuses on the 3D structure prediction problem which has proved to be an elusive goal of molecular biology and biochemistry. The number of local energy minima is exponential in the number of amino acids in the protein. All current methods of 3D structure prediction attempt to alleviate this problem by imposing various constraints that effectively limit the volume of conformational space which must be searched. Our Grand Challenge project consists of two elements: (1) a hierarchical methodology for 3D protein structure prediction; and (2) development of a parallel computing environment, the Protein Folding Workbench, for carrying out a variety of protein structure prediction/modeling computations. During the first three years of this project, we are focusing on the use of two proteins selected from the Brookhaven Protein Data Base (PDB) of known structure to provide validation of our prediction algorithms and their software implementation, both serial and parallel. Both proteins, protein L from {ital peptostreptococcus magnus}, and {ital streptococcal} protein G, are known to bind to IgG, and both have an {alpha} {plus} {beta} sandwich conformation. Although both proteins bind to IgG, they do so at different sites on the immunoglobin and it is of considerable biological interest to understand structurally why this is so. 12 refs., 1 fig.

    The Grand Canyon is one of the most dramatic features on Earth, yet when and why it was carved have been controversial topics for more than 150 years. Here, we present apatite (4)He/(3)He thermochronometry data from the Grand Canyon basement that tightly constrain the near-surface cooling history associated with canyon incision. (4)He/(3)He spectra for eastern Grand Canyon apatites of differing He date, radiation damage, and U-Th zonation yield a self-consistent cooling history that substantially validates the He diffusion kinetic model applied here. Similar data for the western Grand Canyon provide evidence that it was excavated to within a few hundred meters of modern depths by ~70 million years ago (Ma), in contrast to the conventional model in which the entire canyon was carved since 5 to 6 Ma.

    The Grand Canyon, located in Northern Arizona, is one of the seven natural wonders of the world, and has been set aside as a National Park to preserve its unique character. Several million visitors from all over the world travel to the Grand Canyon each year to witness its awesome beauty, As a natural preserve, the area protects numerous values such as genetic diversity, solitude, non-mechanized recreation, etc, but the majority of visitors travel to the Grand Canyon for one reason: to view the scenery.There have been reports in the general press (and even in the United States Congressional Hearings) that visual conditions at the Grand Canyon have been seriously degraded by air pollution. Over the past nine years, a vast array of visibility-related research and monitoring has been conducted to determine the extent and probable cause of this visible degradation. Studies have included optical measurements, pollution characterization, source-receptor relationship analysis, and human perception of visual air quality. The resulting data document the visual air quality of the Grand Canyon and provide a basis to qualitatively and quantitatively evaluate significant events and trends.This poster comprehensively assembles, updates, analyzes and summarizes these various studies to report what has happened to air clarity at the Grand Canyon. The authors examine: - the extent and variation of optical conditions through an examination of reported standard visual range data and a qualitative review of standard photographic monitoring record; - the scientific basis and measurement techniques used to quantify optical conditions; - the probable causes of visual degradation by analyzing the chemical properties of collected aerosols, and through investigation of air mass trajectories; - how visitors to the Grand Canyon perceive and value visual air quality; - the implications study results have for control of air pollutants outside protected natural areas.

    The grand challenges approach aims to spark innovative and transformative strategies to overcome barriers to significant global health issues. Grand Challenges Canada endorses an 'Integrated Innovation™' approach that focuses on the intersection of scientific/technological, social and business innovation. In this article we explore themes emerging from a dialogue between the authors, who are multidisciplinary recipients of the 'Rising Stars in Global Health' award from Grand Challenges Canada, regarding benefits of engaging in integrated innovation research, and recommendations for how this approach may develop in the future. Our dialogue followed a semi-structured interview format that addressed three topics: 1) reflections on applying an Integrated Innovation™ approach for global health; 2) thoughts on participation in the Grand Challenges 2012 meeting; and 3) authors' visions of Grand Challenges Canada and the Grand Challenge movement towards 2020. The dialogue was transcribed verbatim and we used thematic analysis techniques to identify, analyze and report themes in the data. Benefits of working using the Grand Challenges approach centered on two themes: a) the potential for scientific breakthrough and b) building interdisciplinary collaborations and a community of scholars. Challenges and opportunities for Grand Challenges in moving forward included: a) capacity building, particularly regarding Integrated Innovation™ and scale-up planning; b) interdisciplinary and international mentorship for new investigators; and c) potential for future commercialization. Our discussion highlighted that Integrated Innovation™ offers the opportunity to develop new theories, methods and approaches to global health while simultaneously fostering a collaborative spirit grounded in international, interdisciplinary collaborations. However, the arguable over-emphasis on corporatization poses a major challenge for new investigators. We propose a more balanced way forward

    We deal with many-electron systems having a noninteger number of electrons, which cannot be described properly by means of pure states or by canonical statistical ensemble states. The study of the one-electron reduced density matrix for these systems raises the problem of its representability in statistical ensembles of grand canonical type. We derive the necessary and sufficient conditions for the representability of the one-electron reduced density matrix of grand-canonical statistical ensembles.

  11. Formation of the Grand Canyon 5 to 6 million years ago through integration of older palaeocanyons

    The timing of formation of the Grand Canyon, USA, is vigorously debated. In one view, most of the canyon was carved by the Colorado River relatively recently, in the past 5-6 million years. Alternatively, the Grand Canyon could have been cut by precursor rivers in the same location and to within about 200 m of its modern depth as early as 70-55 million years ago. Here we investigate the time of formation of four out of five segments of the Grand Canyon, using apatite fission-track dating, track-length measurements and apatite helium dating: if any segment is young, the old canyon hypothesis is falsified. We reconstruct the thermal histories of samples taken from the modern canyon base and the adjacent canyon rim 1,500 m above, to constrain when the rocks cooled as a result of canyon incision. We find that two of the three middle segments, the Hurricane segment and the Eastern Grand Canyon, formed between 70 and 50 million years ago and between 25 and 15 million years ago, respectively. However, the two end segments, the Marble Canyon and the Westernmost Grand Canyon, are both young and were carved in the past 5-6 million years. Thus, although parts of the canyon are old, we conclude that the integration of the Colorado River through older palaeocanyons carved the Grand Canyon, beginning 5-6 million years ago.

    We investigate the short-term dynamical evolution of stellar grand-design spiral arms in barred spiral galaxiesusing a three-dimensional (3D) N-body/hydrodynamic simulation. Similar to previous numerical simulations of unbarred, multiple-arm spirals, we find that grand-design spiral arms in barred galaxies are not stationary, but rather dynamic. This means that the amplitudes, pitch angles, and rotational frequencies of the spiral arms are not constant, but change within a few hundred million years (i.e. the typical rotational period of a galaxy). We also find that the clear grand-design spirals in barred galaxies appear only when the spirals connect with the ends of the bar. Furthermore, we find that the short-term behaviour of spiral arms in the outer regions (R > 1.5-2 bar radius) can be explained by the swing amplification theory and that the effects of the bar are not negligible in the inner regions (R bar radius). These results suggest that although grand-design spiral arms in barred galaxies are affected by the stellar bar, the grand-design spiral arms essentially originate not as bar-driven stationary density waves, but rather as self-excited dynamic patterns. We imply that a rigidly rotating grand-design spiral could not be a reasonable dynamical model for investigating gas flows and cloud formation even in barred spiral galaxies.

  16. New aspects of flavour model building in supersymmetric grand unification

    2010-05-19

    We derive predictions for Yukawa coupling ratios within Grand Unified Theories generated from operators with mass dimension four and five. These relations are a characteristic property of unified flavour models and can reduce the large number of free parameters related to the flavour sector of the Standard Model. The Yukawa couplings of the down-type quarks and charged leptons are affected within supersymmetric models by tan {beta}-enhanced threshold corrections which can be sizeable if tan {beta} is large. In this case their careful inclusion in the renormalisation group evolution is mandatory. We analyse these corrections and give simple analytic expressions and numerical estimates for them. The threshold corrections sensitively depend on the soft supersymmetry breaking parameters. Especially, they determine the overall sign of the corrections and therefore if the affected Yukawa couplings are enhanced or suppressed. In the minimal supersymmetric extension of the Standard Model many free parameters are introduced by supersymmetry breaking about which we make some plausible assumptions in our first simplified approach. In a second, more sophisticated approach we use three common breaking schemes in which all the soft breaking parameters at the electroweak scale can be calculated from only a handful of parameters. Within the second approach, we apply various phenomenological constraints on the supersymmetric parameters and find in this way new viable Yukawa coupling relations, for example y{sub {mu}}/y{sub s}=9/2 or 6 or y{sub {tau}}/y{sub b}=3/2 in SU(5). Furthermore, we study a special class of quark mass matrix textures for small tan {beta} where {theta}{sup u}{sub 13}={theta}{sup d}{sub 13}=0. We derive sum rules for the quark mixing parameters and find a simple relation between the two phases {delta}{sup u}{sub 12} and {delta}{sup d}{sub 12} and the right unitarity triangle angle {alpha} which suggests a simple phase structure for the quark mass matrices where

  17. Islam and birth planning: an interview with the Grand Mufti of Egypt.

    1981-01-01

    In this interview, Shaikh Jad-al-Hag, the Grand Mufti of Egypt, discusses contraception and abortion in the context of Islamic Law. The Grand Mufti, who is the final authority on al controversial issues that may arise in the interpretation and application of Islamic law, was instrumental in the Egyptian Assembly's recent radical changes in the laws relating to women's rights and status. As the Grand Mufti explains, a Muslim must resolve moral questions according to the Quran, the sayings and acts of the Prophet, and the view of the leaders of juristic schools, who are qualified to interpret the law of Islam. No Quranic text, says the Grand Mufti, forbids prevention of conception. The Prophet's sayings appear to support contraception. And while jurists do no agree on the issues of birth prevention, the eminent jurist Al Ghazali clearly gave his consent for withdrawal as a way to prevent pregnancy in order to save a woman's health and live, avoid financial hardship, or other domestic problems. By analogy, argues the Grand Mufti, modern methods of contraception are permissible, so long as they cause no harm either partner or to their future fecundity. Sterilization is not allowed if this causes a permanent loss of fertility. Coercive population laws are also not allowed. Concerning abortion, the Grand Mufti explains that jurists disagree in the view of the issue. While juristic consensus says that abortion after the first 4 months of pregnancy amounts to the taking of a life, the mother's life generally takes precedence over the child's life. Essentially, the Grand Mufti maintains that abortion at the right time and for the right reason is allowed.

    The Grande Ronde Basin once supported large runs of chinook salmon Oncorhynchus tshawytscha and estimated peak escapements in excess of 10,000 occurred as recently as the late 1950's (U.S. Army Corps of Engineers 1975). Natural escapement declines in the Grande Ronde Basin have been severe and parallel those of other Snake River populations. Reduced productivity has primarily been attributed to increased mortality associated with downstream and upstream migration past eight dams and reservoirs in the Snake and Columbia rivers. Reduced spawner numbers, combined with human manipulation of previously important spawning and rearing habitat in the Grande Ronde Basin, have resulted in decreased spawning distribution and population fragmentation of chinook salmon in the Grande Ronde Basin (Figure 1; Table 1). Escapement of spring/summer chinook salmon in the Snake River basin included 1,799 adults in 1995, less than half of the previous record low of 3,913 adults in 1994. Catherine Creek, Grande Ronde River and Lostine River were historically three of the most productive populations in the Grande Ronde Basin (Carmichael and Boyce 1986). However, productivity of these populations has been poor for recent brood years. Escapement (based on total redd counts) in Catherine Creek and Grande Ronde and Lostine rivers dropped to alarmingly low levels in 1994 and 1995. A total of 11, 3 and 16 redds were observed in 1994 in Catherine Creek, upper Grande Ronde River and Lostine River, respectively, and 14, 6 and 11 redds were observed in those same streams in 1995. In contrast, the maximum number of redds observed in the past was 505 in Catherine Creek (1971), 304 in the Grande Ronde River (1968) and 261 in 1956 in the Lostine River (Tranquilli et al 2003). Redd counts for index count areas (a standardized portion of the total stream) have also decreased dramatically for most Grande Ronde Basin streams from 1964-2002, dropping to as low as 37 redds in the 119.5 km in the index

  20. Promoting Undergraduate Research at Grand Valley State University

    Grand Valley State University (GVSU) is a relatively young, rapidly growing, predominately undergraduate institution of about 20,000 students located in western Michigan in which undergraduate research plays a vital role in the education of our students. Student research is supported and actively promoted by 1) creating university funding opportunities and taking advantage of small outside funding sources 2) building a tradition of undergraduate research 3) incorporating small research activities into classes and 4) educating students explicitly in how to prepare a professional poster, give a professional talk and write a journal article. As the saying goes, if you have money, the students will come. At GVSU most students recognize the value of a research experience but need income to pay for college expenses. The internally funded Student Summer Scholars program at GVSU provides student salary and faculty stipend for a summer research project (\\6000 per grant). The geology department has also been successful at obtaining grants from the NASA Michigan Space Grant Consortium (\\5,000 plus a 100% GVSU match). We have been successful in using these easier to obtain smaller grants to fund undergraduate projects. In some cases small grants actually allow us to pursue "risky" or otherwise difficult to fund projects. Undergraduate research "counts" at GVSU and once a tradition and critical mass of undergraduate research has been established, it can become self-sustaining. To recognize the achievements of undergraduate research at GVSU, there is an annual Student Scholarship Day in which the students (580 university wide) present the results of their research. Also, by persuading students in our introductory classes (for extra credit) to attend Student Scholarship Day, the students, early in their college career, can see what fellow students can accomplish and student presenters can revel in their role of researcher and educator. Such an event helps to build a tradition

    The age and evolution of the Grand Canyon have been subjects of great interest and debate since its discovery. We found that cave mammillaries (water table indicator speleothems) from nine sites in the Grand Canyon showed uranium-lead dating evidence for an old western Grand Canyon on the assumption that groundwater table decline rates are equivalent to incision rates. Samples in the western Grand Canyon yielded apparent water table decline rates of 55 to 123 meters per million years over the past 17 million years, in contrast to eastern Grand Canyon samples that yielded much faster rates (166 to 411 meters per million years). Chronology and inferred incision data indicate that the Grand Canyon evolved via headward erosion from west to east, together with late-stage ( approximately 3.7 million years ago) accelerated incision in the eastern block.

    Thermal histories are modeled from new apatite (U-Th)/He and apatite fission-track data in order to quantitatively constrain the landscape evolution of the Grand Canyon region. Fifty new samples and their associated thermochronometric ages are presented here. Samples span from Lee’s Ferry in the east to Quartermaster Canyon in the west and include four age-elevation transects into Grand Canyon and borehole samples from the Coconino Plateau. Twenty-seven samples are inversely modeled to provide continuous thermal histories. This represents the most extensive and complete dataset on patterns of long-term exhumation in the Grand Canyon region, and it enables us to constrain the timing and magnitude of erosion and also discriminate between canyon incision and broader planation. The new data suggest that the early Cenozoic landscape in eastern Grand Canyon was low in relief and does not indicate the presence of an early Cenozoic precursor to the modern Grand Canyon. However, there is evidence for the incision of a smaller-scale canyon across the Kaibab Uplift at 28–20 Ma. This middle-Cenozoic denudation event was accompanied by the removal of a majority of remaining Mesozoic strata west of the Kaibab Uplift. In contrast, just upstream in the area of Lee’s Ferry, ∼2 km of Mesozoic strata remained over the middle Cenozoic and were removed after 10 Ma.

    Two separate weather systems produced storms resulting in more than 11 inches of rain in parts of Lake County, Ohio, on July 27-28, 2006. As a result of the storms and ensuing flooding caused by the weather systems, the counties of Lake, Geauga, and Ashtabula were declared Federal and State disaster areas, with damages estimated at $30 million and one fatality in Lake County. About 600 people were evacuated in Lake County. The U.S. Geological Survey streamflow-gaging station at Grand River near Painesville, Ohio (station 04212100), had a record peak stage of 19.35 feet (elevation, 614.94 feet), with a record peak streamflow of 35,000 cubic feet per second, and an estimated recurrence interval of approximately 500 years. This report describes the meteorological factors that resulted in severe flooding on the Grand River near Painesville from July 27 to July 31, 2006, and addresses the damages caused by the storms and flooding. Peak-stage, peak-streamflow, and recurrence-interval data are reported for the Grand River near Painesville. A plot of high-water marks is also presented for the Grand River in a reach that includes the City of Painesville, Painesville Township, the Village of Fairport Harbor, and the Village of Grand River.

Cooling models and geologic data are most consistent with a 5 to 6 Ma age for western Grand Canyon and Marble Canyon.

    This book presents a key piece of the vision and strategy developed in STELLAR. It sets out a new mid-term agenda by defining Grand Challenges for research and development in technology-enhanced learning. Other than mere technology prizes, STELLAR Grand Challenges deal with problems at the interface of social and technical sciences. They pose problems that can be solved only in interdisciplinary collaboration. The descriptions of the Grand Challenge Problems were sent out to a number of stakeholders from industry, academia, and policy-making who responded with insightful, creative and critical comments bringing in their specific perspectives. This book will inspire everyone interested in TEL and its neighboring disciplines in their future projects. All of the listed problems, first hints with respect to the approach, measurable success indicators and funding sources are outlined. The challenges focus on what noted experts regard as important upcoming, pending, and innovative fields of research, the solution o...

    The very existence of Grand Canyon inspires questions about why canyons are carved, how drainage systems and landscapes evolve, and how these processes relate to the elevation gain of plateaus. Yet when and why Grand Canyon was carved have been extraordinarily controversial for more than 150 years. Over the last several decades, the dominant view for the origin of the canyon is one of rapid incision at 5-6 Ma, when detritus derived from the upstream reaches of the Colorado River system appeared in Grand Wash Trough at the Colorado River's western exit from the Colorado Plateau. The absence of such diagnostic deposits prior to 6 Ma has been used to argue that Grand Canyon was not yet excavated (e.g., Karlstrom et al., 2008). However, a variety of data hint at a more ancient age for part or all of the canyon, and it has been proposed that a smaller drainage basin in largely carbonate lithologies could explain the absence of pre-6 Ma Colorado River clastics in Grand Wash Trough even if a significant Grand Canyon were present. Most recently, apatite (U-Th)/He (AHe) thermochronometry data from western Grand Canyon were used to infer excavation of this area to within several hundred meters of its modern depth by ca. 70 Ma (Wernicke, 2011), an interpretation in direct conflict with the young canyon model. The unexpected implications of the initial Grand Canyon AHe work motivated the apatite 4He/3He and U-Th zonation study presented here. Apatite 4He/3He thermochronometry provides information about the spatial distribution of radiogenic 4He in an apatite crystal that can better constrain a sample's cooling history. A key premise of AHe and 4He/3He spectra interpretation is that the He kinetic model used is accurate. We first investigate whether differing 4He/3He spectra for apatites of variable AHe date, radiation damage, and U-Th zonation from eastern Grand Canyon yield mutually consistent thermal history results using the RDAAM kinetic model, which must be true if the

    Full Text Available KASCADE-Grande is an air-shower observatory devoted for the detection of cosmic rays with energies in the interval of 1014 – 1018 eV, where the Grande array is responsible for the higher energy range. The experiment comprises different detection systems which allow precise measurements of the charged, electron and muon numbers of extensive air-showers (EAS. These data is employed not only to reconstruct the properties of the primary cosmic-ray particle but also to test hadronic interaction models at high energies. In this contribution, predictions of the muon content of EAS from QGSJET II-2, SIBYLL 2.1 and EPOS 1.99 are confronted with the experimental measurements performed with the KASCADE-Grande experiment in order to test the validity of these hadronic models commonly used in EAS simulations.

    The World Water and Agriculture Model has been used to simulate water, hydropower, and food sector effects in Egypt, Sudan, and Ethiopia during the filling of the Grand Ethiopian Renaissance Dam reservoir. This unique capability allows tradeoffs to be made between filling policies for the Grand Ethiopian Renaissance Dam reservoir. This Nile River Basin study is presented to illustrate the capacity to use the World Water and Agriculture Model to simulate regional food security issues while keeping a global perspective. The study uses runoff data from the Intergovernmental Panel for Climate Change Coupled Model Inter-comparison Project Phase 5 and information from the literature in order to establish a reasonable set of hydrological initial conditions. Gross Domestic Product and population growth are modelled exogenously based on a composite projection of United Nations and World Bank data. The effects of the Grand Ethiopian Renaissance Dam under various percentages of water withheld are presented.

    Even with long-standing management and extensive science support, North American inland fish and fisheries still face many conservation and management challenges. We used a grand challenges approach to identify critical roadblocks that if removed would help solve important problems in the management and long-term conservation of North American inland fish and fisheries. We identified seven grand challenges within three themes (valuation, governance, and externalities) and 34 research needs and management actions. The major themes identified are to (1) raise awareness of diverse values associated with inland fish and fisheries, (2) govern inland fish and fisheries to satisfy multiple use and conservation objectives, and (3) ensure productive inland fisheries given nonfishing sector externalities. Addressing these grand challenges will help the broader community understand the diverse values of inland fish and fisheries, promote open forums for engagement of diverse stakeholders in fisheries management, and better integrate the inland fish sector into the greater water and land use policy process.

  19. Could a future "Grand Solar Minimum" like the Maunder Minimum stop global warming?

    A future Maunder Minimum type grand solar minimum, with total solar irradiance reduced by 0.25% over a 50 year period from 2020 to 2070, is imposed in a future climate change scenario experiment (RCP4.5) using, for the first time, a global coupled climate model that includes ozone chemistry and resolved stratospheric dynamics (Whole Atmosphere Community Climate Model). This model has been shown to simulate two amplifying mechanisms that produce regional signals of decadal climate variability comparable to observations, and thus is considered a credible tool to simulate the Sun's effects on Earth's climate. After the initial decrease of solar radiation in 2020, globally averaged surface air temperature cools relative to the reference simulation by up to several tenths of a degree Centigrade. By the end of the grand solar minimum in 2070, the warming nearly catches up to the reference simulation. Thus, a future grand solar minimum could slow down but not stop global warming.

    Full Text Available Abstract On February 15, 2008, the National Academy of Engineering unveiled their list of 14 Grand Challenges for Engineering. Building off of tremendous advancements in the past century, these challenges were selected for their role in assuring a sustainable existence for the rapidly increasing global community. It is no accident that the first five Challenges on the list involve the development of sustainable energy sources and management of environmental resources. While the focus of this review is to address the single Grand Challenge of "develop carbon sequestration methods", is will soon be clear that several other Challenges are intrinsically tied to it through the principles of sustainability. How does the realm of biological engineering play a role in addressing these Grand Challenges?
