    In accordance with a study of the International Organization of Work (OIT), to the year around 250 million labor accidents occur, most of them in non-developed or developing countries, and a smaller percentage occurs in the industrialized countries. Analyzing the reason for that difference, it is possible to say that it is mainly due to the fact that in developed countries a greater conscience for the safety has been taken, as much for the personnel as for the facilities within the company, and have developed what is known as the management of the safety systems (SAS), where the safety task no longer corresponds only to the safety department but to the entire personnel, from the direction to the last one of the workers. [Spanish] De acuerdo con un estudio de la Organizacion Internacional del Trabajo (OIT), al ano se producen alrededor de 250 millones de accidentes laborales. La mayoria de ellos se presentan en los paises no desarrollados o en vias de desarrollo, y un porcentaje menor se da en los paises industrializados. Analizando el porque de esa diferencia, se puede decir que se debe principalmente a que en los paises desarrollados se ha tomado una mayor conciencia por la seguridad, tanto del personal como de las instalaciones, dentro de las empresas y han desarrollado lo que se conoce como los sistemas de administracion de seguridad (SAS), en donde la tarea de seguridad ya no solo corresponde al departamento de seguridad si no a todo el personal, desde la direccion hasta el ultimo de los trabajadores.

    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.

    DEFINICIÓN DE LA RESISTENCIA

    De acuerdo al COC (Centro de Control de Enfermedades de Estados Unidos, la resistencia se da cuando un medicamento deja de inhibir el crecimiento o matar un microorganismo. 

    Hay dos tipos de resistencia la adquirida y la clínica. La adquirida se realiza en el laboratorio a través de las mutaciones o por transferencia de genes, sistemas de conjugación, transducción y transformación.

    La resistencia clínica es la observada en la práctica médica, donde no todos los organismos son igualmente sensibles o resistentes a cierto antibiótico y que requiere la ayuda de técnicas de laboratorio para medir cuantitativamente o cualitativamente dicho proceso.

    MECANISMOS DE LA RESISTENCIA BACTERIANA

    En la detección de la Resistencia Bacteriana se han identificado diferentes mecanismos utilizados por las bacterias: destrucción o inactivación enzimática, cambios en la permeabilidad de la membrana interna, alteraciones de los precursores de la pared celular, de la membrana y de los ribosomas.

    Para los años 90 se dispuso de una serie de antimicrobianos como betalactámicos, aminoglucósidos, macrólidos, sulfonamidas, trimetoprim, cloranfenicol, glicopéptidos, rifampicina, quinolonas, tetraciclinas....

     

  8. El comportamiento animal como escudo para evitar la enfermedad y remedio hacia la salud (algunas bases fisiológicas

    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 A SOCIEDADE brasileira recebe, anualmente, a estimativa de perda de floresta na Amazônia por meio da taxa de desflorestamento divulgada pelo Inpe, a qual, em 2004, foi de aproximadamente 26.130 km² . O que não se conhece é o quanto de recursos naturais se perde a cada quilômetro quadrado de floresta destruída. Neste trabalho, apresentamos números concretos desta perda, baseados em estudos recentes sobre a densidade de plantas e de alguns grupos de animais na Amazônia. Com base nisso, defendemos a idéia de que não há necessidade de se ampliar o desflorestamento na região e que, portanto, qualquer licença de desmatamento deveria ser proibida na Amazônia. Sugerimos também que o sistema de ciência e tecnologia regional deve ser descentralizado através do desenvolvimento de programas de pesquisa integrados, focalizados no desenho e no teste de modelos de territórios sustentáveis para os diferentes setores da região.BRAZILIAN society receives yearly an estimate of the Amazonian rainforest loss by means of a deforestation rate announced by Inpe, which in 2004 was of approximatly 26,130 km². What we do not know is how much of the natural resources is lost in each square kilometer of forest destruction. In this work, we present concrete numbers of forest loss, based on recent studies of plant densities and some animal species in the Amazon region. Our findings support the idea that it is not necessary to extend further deforestation in the region and, therefore, that deforestation licenses should be forbidden. Moreover, we propose that regional science and technology system must be gradually descentralized and enhanced through the integration and development of research programs focused in drawing and testing models of sustainable territories for the different social segments of the region.

    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 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 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 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 Although admittedly transmission of Trypanosoma cruzi infection through breastfeeding is a rare event, it involves serious risks. To test the effectiveness of pasteurization in preventing this mode of infection, three sets of samples of human milk were tested: a - contaminated with T. cruzi and pasteurized; b - contaminated with T. cruzi and non-pasteurized; c - non-contaminated and pasteurized. Samples from all sets were orally and intraperitoneally administered to 90 BALB/c mice. The animals inoculated with contaminated, non-pasteurized samples, got the infection. Controls and the animals inoculated with contaminated and pasteurized milk were not infected. The hypothesis was accepted that pasteurization inactivates T. cruzi trypomastigotes.A amamentação é modo alternativo de transmitir-se a doença de Chagas. Embora admitida como evento raro, a infecção por esta via é preocupante. Para evitá-la é sugerida a pasteurização. Separaram-se para o ensaio três conjuntos de amostras de leite humano: a - contaminadas por Trypanosoma cruzi e pasteurizadas; b - contaminadas por T. cruzi e não pasteurizadas; c - não contaminadas e pasteurizadas. Frações dos três conjuntos foram inoculadas por vias oral e intraperitoneal em 90 camundongos BALB/c. Os animais inoculados com leite contaminado e não pasteurizado infectaram-se. Os controles e os inoculados com leite contaminado e pasteurizado não se infectaram. Aceitou-se a hipótese de a pasteurização ter inativado as formas tripomastigotas de T. cruzi em suspensão no leite.

    Full Text Available Working accidents have a high moral and material impact, and are often easy to avoid, at least in about half the cases. Hence it is most important that campaigns for the reduction of these accidents should be correctly planned, so that such campaigns should not merely result in additional expense, and in a lowering of staff morale, when workers find themselves operating in an unpleasant and dangerous activity. In addition to special requirements, which may be studied in a later paper, and which must necessarily cover a very wide number of alternative cases, there are circumstances of a general nature, such as financial and moral consequences, and psychological repercussions, which influence the prevention of accidents and are the subject of this article.La notable repercusión moral y material que tienen los accidentes de trabajo y la fácil evitación de los mismos, por lo menos en la mitad de los casos, hacen sumamente importante que las campañas de prevención de accidentes estén bien orientadas y proyectadas, para evitar que se traduzcan, únicamente, en un gasto más y en una disminución de la moral del personal, al ver, éste, que está situado en medio de un ambiente desagradable y peligroso. Además de las normas particulares, que pueden ser objeto de otro trabajo posterior, y que han de ser forzosamente amplias, debido a la multiplicidad de factores que intervienen, hay, sin embargo, unas consideraciones de carácter general, tales como repercusiones económicas y morales y factores psicológicos que influyen en la prevención de accidentes y que son objeto del presente artículo.

    Full Text Available ResumenLa presencia o no de factores psicológicos de riesgo para la aparición de distintas enfermedades continúa siendo un tema controvertido en las ciencias médicas y psicológicas, quizás por las dificultades que se presentan en el momento de su evaluación. No obstante, ya se han realizado primeras miradas en este sentido, presentando la siguiente investigación en personas con accidente cerebrovascular, como un análisis preliminar experimental; que más que brindar datos definitorios, permita a la vez, abrir nuevos caminos hacia la búsqueda de la multideterminación de los procesos patológicos. Con el objetivo central de determinar factores psicológicos de riesgo para la aparición de los accidentes cerebrovasculares, se establecieron dos grupos de estudio y testigo, a los cuales se le aplicaron el test de depresión Zung-Conde, el IDARE, el cuestionario de conductas de enfrentamiento y el examen neuropsicológico de Anne-Lise Crhistensen. Se pudo definir la existencia de factores más relacionados con características personológicas, factores externos fundamentalmente provenientes del medio y factores producto de esta interacción como lo constituyen el estrés y la ansiedad.

    Accidental situations in NPP are great concern for operators, the facility, regulatory bodies and the environmental. This work proposes a design of intelligent system aimed to assist the operator in the process of decision making initiator events with higher relative contribution to the reactor core damage occur. The intelligent System uses the results of the pre-operational Probabilistic safety Assessment and the Thermal hydraulic Safety Analysis of the NPP Juragua as source for building its knowledge base. The nucleus of the system is presented as a design of an intelligent hybrid from the combination of the artificial intelligence techniques fuzzy logic and artificial neural networks. The system works with variables from the process of the first circuit, second circuit and the containment and it is presented as a model for the integration of safety analyses in the process of decision making by the operator when tackling with accidental situations

    Full Text Available En los últimos 20 años se han desarrollado nuevas opciones para el tratamiento y para la prevención del accidente cerebrovascular (ACV isquémico, muchas de ellas de carácter intervencionista, tales como la endarterectomía carotídea y la trombolisis intravenosa con activador tisular del plasminógeno. La evidencia científica ha llevado a su difusión y utilización en países desarrollados mientras que en naciones emergentes se observa un retraso en su adopción. Otras modalidades terapéuticas que parecen ser muy promisorias, aunque sin tanta evidencia científica que las avale, requieren la realización y conclusión de estudios randomizados. Dentro de la evolución del ACV isquémico existe una situación particular como es el infarto cerebral "maligno". Constituye un evento devastador, que se presenta en aproximadamente el 10 al 15% de los ACV carotídeos o silvianos, y está asociado con elevada morbimortalidad. Con la información disponible actualmente, es posible recomendar la craniectomía descompresiva (CD como un método efectivo y seguro para disminuir rápidamente la presión intracraneal y lograr un pronóstico favorable sobre una base racional. Aunque no hay estudios randomizados y controlados en la literatura, existe suficiente evidencia para recomendar la CD en casos especiales.New options have been developed for the prevention and treatment of acute ischemic stroke in the last 20 years, such as carotid endarterectomy and intravenous thrombolysis with tissue plasminogen activator. Scientific evidence has supported their use in developed countries, while there is an evident delay in their use among emerging countries. Other promising modalities require the conclusion of ongoing randomized, controlled trials. Malignant middle or carotid cerebral artery infarction accounts for 10 to 15% ischemic strokes and constitutes a devastating event associated with high morbidity and mortality.

As crianças do sexo masculino tiveram 30% mais de chances de se lesionarem do que aquelas do sexo feminino, e as crianças brancas tiveram um risco 70% maior do que as crianças não-brancas. Renda familiar, escolaridade dos pais e trabalho materno não se associaram à ocorrência de injúrias. Após ajuste para variáveis socioeconômicas e ambientais, as crianças que possuíam um ou mais irmãos menores apresentavam taxa 30% maior de injúrias acidentais. Crianças residentes em casa de tijolo apresentaram uma incidência de injúrias cerca de 40%superior. Conclusões: poucos fatores de risco modificáveis foram associados a um aumento na freqüência de injúrias acidentais.

Objetivo: evaluar la correspondencia de la línea del pliegue antecubital interno con la epitróclea en pacientes con fractura supracondílea y la incidencia de las lesiones iatrogénicas del nervio cubital. Metodología: Realizamos una serie de casos clínicos. El primer grupo incluyó 56 niños con fractura supracondílea tipo III de Gartland, entre agosto de 2000 a septiembre de 2007, tratados con reducción cerrada y fijación con clavos cruzados retrógrados. El segundo grupo incluyó 241 (481 codos pacientes de consulta externa. En ambos grupos utilizamos la línea antecubital interna para identificar la epitróclea. Resultados: La prolongación de la línea del pliegue antecubital intersecó la epitróclea en todos los participantes del primer grupo. No hubo lesión iatrogénica del nervio cubital. En el segundo grupo la línea del pliegue antecubital intersecó la epitróclea en el 96.3% de los pacientes. Ningún paciente presentó lesión del nervio cubital. Conclusiones: La extensión de la línea de pliegue antecubital interno puede ser útil para la identificación de la epitróclea y así evitar lesiones iatrogénicas del nervio cubital.

    Introducción la retención laboral es un tema de suma importancia, porque se requiere de profesionales en el primer nivel de atención (PNA). El objetivo fue determinar si los accidentes laborales se asociaron al desánimo de los médicos para trabajar en el PNA de Lima, Perú. Métodos estudio transversal analítico de datos secundarios de una base de datos generada de una encuesta a médicos que realizaron su Servicio Rural y Urbano-Marginal en Salud (SERUMS). Se incluyó solo a los médicos que manifestaron al inicio del SERUMS que podían trabajar en el PNA de Lima. Se definió como cambio de intención de trabajo en el PNA a los que finalizando el SERUMS refirieron que ya no deseaban laborar en Lima. Esto se asoció según si tuvieron un accidente laboral y se ajustó por otras variables. Resultados de los 124 médicos el 63% fueron hombres (78). La mediana de edad fue de 26 años (rango intercuartílico: 25-27 años). Después de su SERUMS, el 12% (15) manifestó que cambió su interés y que deseaba trabajar en la capital. En el análisis multivariado, haber tenido un accidente laboral disminuyó la frecuencia del cambio de intención de trabajo en el PNA (RPa: 0.28, IC 95%: 0.14-0.54, p de trabajar en provincias, pero nuestro estudio dice lo contrario, posiblemente por la percepción de que un trabajo en la capital del país permite estar más cerca de los servicios para ser atendido en caso de cualquier emergencia.

    Full Text Available A decomposição de amostras que contêm elevados teores de Si, utilizando mistura com os ácidos nítrico e fluorídrico, pode provocar a precipitação de fluoretos de Al(III, Ca(II, Fe(III e Mg(II durante a digestão, impedindo a recuperação total desses elementos. Visando minimizar esse problema, foram testados quatro procedimentos aplicados a diferentes amostras de solos. O procedimento mais eficiente envolveu a decomposição assistida por radiação microondas, seguida pela separação do material sólido residual com elevado teor de Si do sobrenadante ácido. A fração residual foi solubilizada usando HF concentrado e, após complexação com ácido bórico, essa solução foi misturada à fase líquida do digerido. Os teores de metais nos digeridos foram determinados por espectrometria de emissão óptica em plasma induzido (ICP OES e a exatidão foi demonstrada aplicando o procedimento proposto em amostras provenientes do programa colaborativo International Soil-Analytical Exchange (ISE, Wegening Agricultural University, Holanda e em amostra certificada de solo proveniente do National Institute of Standard and Technology (NIST, SRM 2709, que apresentou respectivamente, os seguintes percentuais de recuperação: 100,0 ± 2,6; 99,5 ± 1,9; 108,5 ± 2,7; 94,6 ± 8,9; 92,2 ± 9,7; 95,7 ± 1,8; 96,7 ± 2,7; 95,2 ± 0,6; 103,6 ± 2,6 e 96,1 ± 1,6 para, Al, Ba, Ca, Cr, Cu, Fe, Mg, Mn, V e Zn.The use of pre-mixed nitric and hydrofluoric acids for the decomposition of samples containing high amounts of Si can cause the precipitation of Al(III, Ca(II, Fe(III, and Mg(II fluorides during digestion, reducing the total recovery of these elements. Four procedures were applied to certified soil samples in an attempt to circumvent this problem. The most efficient procedure was based on microwave-assisted acid digestion decomposition of the samples, followed by separation of the residual silicate compounds.

    We consider a new approach to fermion masses and mixings in which no special 'horizontal' dynamics is invoked to account for the hierarchical pattern of charged fermion masses and for the peculiar features of neutrino masses. The hierarchy follows from the vertical, family-independent structure of the model, in particular from the breaking pattern of the Pati-Salam group. The lightness of the first two fermion families can be related to two family symmetries emerging in this context as accidental symmetries

    Accidental matter models are scenarios where the beyond-the-standard model physics preserves all the standard model accidental and approximate symmetries up to a cutoff scale related with lepton number violation. We study such scenarios assuming that the new physics plays an active role in neutrino mass generation, and show that this unavoidably leads to radiatively induced neutrino masses. We systematically classify all possible models and determine their viability by studying electroweak precision data, big bang nucleosynthesis and electroweak perturbativity, finding that the latter places the most stringent constraints on the mass spectra. These results allow the identification of minimal radiative accidental matter models for which perturbativity is lost at high scales. We calculate radiative charged-lepton flavor violating processes in these setups, and show that μ→eγ has a rate well within MEG sensitivity provided the lepton-number violating scale is at or below 5×10{sup 5} GeV, a value (naturally) assured by the radiative suppression mechanism. Sizeable τ→μγ branching fractions within SuperKEKB sensitivity are possible for lower lepton-number breaking scales. We thus point out that these scenarios can be tested not only in direct searches but also in lepton flavor-violating experiments.

La tasa de respuesta a un cuestionario estructurado que respondieron en forma anónima fue del 75,8 % (n= 562. El análisis de los datos incluyó la búsqueda de agrupamientos espaciales para poblaciones de distribución heterogénea utilizando el programa SatScan versión 9.2. La frecuencia de accidentes fue del 14,8 %. Se encontró un agrupamiento espacial (p= 0,017 en el sudeste provincial (riesgo relativo= 0,42. La frecuencia de veterinarios que sufrieron accidentes fue decreciendo desde el norte al sur de la provincia. El tránsito en rutas fue percibido como más riesgoso por una mayor proporción de entrevistados que el tránsito en caminos rurales. Las frecuencias de uso de luz baja durante el día y cinturón de seguridad fueron independientes de las percepciones del riesgo en el tránsito. Dado que la frecuencia de accidentes entre los veterinarios es alta, resulta fundamental diseñar estrategias de educación para evitar daños futuros.

    2002-11-01

    The acoustical phenomenon observed at an ancient temple in the Great Ball Court at Chichen Itza was described as ''little short of amazing--an ancient whispering gallery'' by Silvanus G. Morley, leader of the Carnegie Institute's archaeological team that excavated and restored these structures in the 1920s. Since then, many others have experienced the extraordinary acoustics at Chichen Itza and other Maya sites. Despite these reports, archaeologists and acousticians have until recently shown little interest in understanding these phenomena. After experiencing Chichen Itza's remarkable acoustics as a tourist in 1994, the author commenced collecting and disseminating information about acoustical phenomena there and at other Mayan sites, hoping to stimulate interest among archaeologists and acousticians. Were these designs accidental or intentional? If intentional, how was the knowledge obtained? How were acoustical features used? This paper highlights the author's collection of anecdotal reports of mysterious Mayan acoustics (http://http://www.ianlawton.com/pa1.htm), recommended reading for scientists and engineers who wish to pursue this fascinating study. Also recounted are some of the reactions of archaeologists-ranging from curious, helpful, and insightful to humorous and appalling--to outsiders' efforts to bring serious scientific attention to the new field of acoustical archaeology.

    Full Text Available OBJECTIVE: to examine the transition of care in families caring for elderly persons who suffered the first episode of a cerebrovascular accident. METHODOLOGY: an instrumental ethnographic case study was used. The sample comprised 20 subjects: 10 caregivers and 10 elderly persons aged 65 or over, of both sexes, with diagnoses of first episode of cerebrovascular accident, capable of communicating, and requiring care from a main carer in their family. The data was collected through interviews, observation, existing documentation and field notes. Qualitative analysis techniques were used to codify and classify the data and to formulate significant categories, which generated typologies of care. RESULTS AND DISCUSSION: The central idea was the Transition of Care and showed the context in three typologies: The care process for the dependent elderly person, Strategies for the care process and Impact and acceptance of the limitations. CONCLUSION: The data indicates that caring for an elderly person after a cerebrovascular accident is a challenge for the family. The data permitted it possible to elaborate a proposal for a model for the organization of the work, with a view to holistic care delivery in the health services, forming a care network, which constitutes an advance for the area of nursing.OBJETIVO: examinar la transición del cuidado en familias que cuidan de adultos mayores que sufrieron el primer episodio de accidente cerebral vascular.

    Full Text Available RESUMEN: El presente estudio se trata de una investigación experimental para intentar predecir la variabilidad que se puede producir por la influencia de una campaña publicitaria con el objetivo de prevenir los accidentes de tráfico en los niños de seis a catorce años. Más concretamente, se desarrollan todos los elementos que han intervenido en la aplicación educativa de un programa, que pretende modificar los niveles de error que cometen los niños en los pasos para peatones regulados con semáforo. El instrumento de intervención educativa consistió en un folleto que se facilitó a los alumnos y en un cartel que se situaba en las aulas, y en donde aparecen matizadas las conductas adecuadas que se han de llevar a cabo en el mencionado paso para peatones. El procedimiento se basa en las estrategias de las intervenciones experimentales, pero teniendo presente los factores que condicionan los resultados de las aplicaciones en los programas aplicados en un medio natural. Los resultados de la aplicación experimental han sido significativos, aunque hay que tener la influencia de algunos factores que han condicionado parte de los resultados. Asimismo, además de la conducta de los niños, se evaluó la conducta de los adultos, obteniéndose en todos los casos una variabilidad menor que en los primeros.ABSTRACT: The present study deals with experimental research that attempted to pre-- dict the variability that can be produced by the influence of an advertising campaign aimed at preventing traffic accidents in children aged six to fourteen. More concretely, we analyzed the elements that intervened in the educational application of a program aimed at modifying the number of errors committed by children at cross-walks regulated by traffic lights. The instrument of educational intervention consisted of a leaflet given to the students and a poster put up in the classroom, which showed the proper behaviour for using pedestrian cross-walks. The

    Full Text Available Dos recientes pronunciamientos de la Sala 4 ª de lo Social del Tribunal Supremo han puesto fin a la doctrina jurisprudencial por la que, para evitar el "enriquecimiento injusto" del trabajador accidentado, se exoneraba al empresario del deber de reparar los perjuicios causados en un accidente de trabajo o enfermedad profesional, por el incumplimientos de sus obligaciones en materia de seguridad. Este cambio jurisprudencial obliga a abordar la cuantificación económica de los distintos componentes indemnizatorios. En este trabajo ofrecemos un novedoso método para la evaluación económica directa del daño moral basado los años de vida ajustados por calidad perdidos por los trabajadores que sufren un accidente de trabajo. El método propuesto se ofrece como una alternativa ventajosa frente a la utilización del baremo de tráfico.Two recent Social Supreme Court rulings have put an end to the jurisprudential doctrine that prevented the "unfair enrichment" of an injured worker. This doctrine exempted the employer from the obligation of repairing the damage caused by work accidents or occupational diseases, stemming from breaches of the employer’s security obligations. The jurisprudential change requires addressing the economic quantification of the various components of workers’ compensation. Our study offers a novel method for assessing the economic value of moral damage based on Quality Adjusted Life Years lost by workers who suffer a work accident. The proposed method is presented as an alternative that is more appropriate than the use of the traffic scale.

    EDF ordered to FRAMATOME by 1977 to complete post accidental long term studies on 'First Contrat-Programme' reactors, in order to demonstrate the safety criteria long term compliance, to get information on NSSS behaviour and to improve the post accidental procedures. Convenient analytical models were needed and EDF and FRAMATOME respectively developped the AXEL and FRARELAP codes. The main results of these studies is that for the smallest breaks, it is possible to manually undertake cooling and pressure reducing actions by dumping the steam generators secondary side in order to meet the RHR operating specifications and perform long term cooling through this system. A specific small breaks procedure was written on this basis. The EDF and FRAMATOME codes are continuously improved; the results of a French set of separate effects experiments will be incorporated as well as integral system verification

In spite of the efforts before mentioned a potential possibility of occurrence of accidental radiological events linked to human errors and violation's of the principles of the radiation protection exists. Reason that they advise to have response capacities to confront and to mitigate the consequences in situations of radiological accidents, including in the same ones the medical assistance of the accident victims. However, the radiological accidents happened in the international environment in the last decades, they have demonstrated inability paradoxically to confront with effectiveness these fortuitous events. Being characterized additionally by the insufficient training of the medical professionals to interpret and to act in consequence before the prejudicial effects to the health of the ionizing radiation.

  1. Is the tribimaximal mixing accidental?

    International Nuclear Information System (INIS)

    Abbas, Mohammed; Smirnov, A. Yu.

    2010-01-01

    The tribimaximal (TBM) mixing is not accidental if structures of the corresponding leptonic mass matrices follow immediately from certain (residual or broken) flavor symmetry. We develop a simple formalism which allows one to analyze effects of deviations of the lepton mixing from TBM on the structure of the neutrino mass matrix and on the underlying flavor symmetry. We show that possible deviations from the TBM mixing can lead to strong modifications of the mass matrix and strong violation of the TBM-mass relations. As a result, the mass matrix may have an 'anarchical' structure with random values of elements or it may have some symmetry that differs from the TBM symmetry. Interesting examples include matrices with texture zeros, matrices with certain 'flavor alignment' as well as hierarchical matrices with a two-component structure, where the dominant and subdominant contributions have different symmetries. This opens up new approaches to understanding the lepton mixing.

    2012-01-01

    Retrospective dosimetry is one of the most important tools of accidental dosimetry for dose estimation when dose measurement was not planned. In the affected area many objects can be applied as natural dosimeters. The paper discusses our recent investigations on various electronic components and common salt (NaCl) having useful thermoluminescence (TL) properties. Among materials investigated the electronic components of cell phones seem promising for retrospective dosimetry purposes, having high TL responses, proper glow curve peaks and the intensity of TL peaks vs. gamma dose received provided nearly linear response in the dose range of 10 mGy–1.5 Gy. - Highlights: ► Electronic components and common salt were investigated for accidental and retrospective dosimetry. ► SMD resistors seem promising for retrospective dosimetry purposes. ► Table salt can be used effectively for accidental dosimetry purposes, as well.

    As interim substance in the nuclear fuel enrichment process, Uranium Hexafluoride (UF 6 ) is widely applied in nuclear processing, enrichment and fuel fabrication plants. Because of its vivid chemical characteristics and special radiological hazard and chemical toxicity, great attention must be paid to accident of UF 6 leakage. The chemical reactions involved in UF 6 release processes were introduced, therewith potential release styles, pathways and characteristics of diffusion were analyzed. The results indicated that the accidental release process of UF 6 is not a simple passive diffusion. So, specific atmospheric diffusion model related to UF 6 releases need be used in order to analyze and evaluate accurately the accidental consequences. (authors)

El objetivo de este trabajo es describir la evolución temporal de los accidentes de trabajo (AT y determinar los factores de riesgo de baja médica en el Hospital Dr. Peset de Valencia. MÉTODOS: Descripción y análisis retrospectivo de los accidentes de trabajo producidos en el Hospital Dr. Peset de Valencia durante los años 1992 a 1995. Se estimó por métodos deterministas la tendencia y estacionalidad de las series (índices estacionales, IE. Se aplicó un modelo de regresión logística para identificar los factores pronósticos de baja médica y determinar su probabilidad de ocurrencia . RESULTADOS: Las tasas más elevadas de AT se produjeron entre los trabajadores de cocina y lavandería (10,00 AT por 100 trabajadores-año. Los AT con baja médica mantienen una tendencia cercana a cero siendo febrero el mes con I.E más elevado (IE=139,8. Los que cursan sin baja médica tienen una tendencia positiva (r²=0,23, p<0,0001, siendo mayo el mes de mayor siniestralidad (IE=134,2. La probabilidad de que el accidente curse con baja médica aumenta significativamente con la edad, cuando se produce por la tarde, si ha tenido lugar en cocina/lavandería, y si se trata de un esguince o tendinitis. CONCLUSIONES: la actuación sobre la siniestralidad en los AT que cursen con IT, debería centrarse sobre los trabajos menos cualificados y en las áreas de cocina y lavandería.

    ) [Spanish] En los dosimetros para caso de accidente nuclear se han empleado como gammametro diversos tipos de detectores gamma, tales como dosimetros de vidrio, dosimetros de pelicula, dosimetros quimicos y dosimetros de polimerizacion. Pero el autor llego a la conclusion de que el dosimetro de termoluminiscencia ofrece notables ventajas sobre todos esos tipos. El amplio intervalo de medicion del dosimetro de termoluminiscencia permite, en efecto, su empleo como aparato de control radiologico cotidiano y como dosimetro para caso de accidente. Esta duplicidad elimina la necesidad de disponer de instrumentos especiales para la dosimetria en caso de accidente, y permite utilizar con tal objeto los instrumentos, de uso diario, bien calibrados. Por regla general, el intervalo de medicion propio del dosimetro de termoluminiscencia abarca desde 5 mr a 100 000 r, con reproducibilidad de {+-}10%. El autor ha disenado y construido un dosimetro de fluoruro de calcio, de tipo unico, asi como el correspondiente equipo para su lectura, cuyo intervalo de medicion es de 5 mr a 5000 r. La lectura del dosimetro se efectua calentando el fosforo y midiendo la luz emitida. Se dispone de instrumentos para lecturas que abarcan seis potencias de diez y se han disenado sistemas totalmente automatizados. La lectura con ayuda de estos aparatos solo exige 20 s por dosimetro. Otra ventaja del dosimetro de termoluminiscencia es su baja respuesta neutronica. Esta respuesta variara con el tipo de envoltura y con la naturaleza del fosforo empleados. Un determinado tipo de dosimetro de fluoruro de calcio tiene una respuesta neutronica de 0,27 *10{sup -9} rad/n * cm{sup 2}. El autor describe dos modelos de dosimetros de termoluminiscencia. El primero consiste en un dosimetro de calentamiento interno encerrado en una capsula de vidrio en cuyo interior se ha hecho el vacio; sus dimensiones aproximadas son: 1 cm de diametro y 6 cm de longitud. El segundo modelo esta formado por un tubo de vidrio de pequeno

    Whereas adults largely base their evaluations of others' actions on others' intentions, a host of research in developmental psychology suggests that younger children privilege outcome over intention, leading them to condemn accidental harm. To date, this question has been examined only with children capable of language production. In the current studies, we utilized a non-linguistic puppet show paradigm to examine the evaluation of intentional and accidental acts of helping or harming in 10-month-old infants. In Experiment 1 (n=64), infants preferred intentional over accidental helpers but accidental over intentional harmers, suggestive that by this age infants incorporate information about others' intentions into their social evaluations. In Experiment 2 (n=64), infants did not distinguish "negligently" accidental from intentional helpers or harmers, suggestive that infants may find negligent accidents somewhat intentional. In Experiment 3 (n=64), we found that infants preferred truly accidental over negligently accidental harmers, but did not reliably distinguish negligently accidental from truly accidental helpers, consistent with past work with adults and children suggestive that humans are particularly sensitive to negligently accidental harm. Together, these results imply that infants engage in intention-based social evaluation of those who help and harm accidentally, so long as those accidents do not stem from negligence.

    We study a model of accidental inflation in type IIB string theory where inflation occurs near the inflection point of a small Kähler modulus. A racetrack structure helps to alleviate the known concern that string-loop corrections may spoil Kähler Moduli Inflation unless having a significant suppression via the string coupling or a special brane setup. Also, the hierarchy of gauge group ranks required for the separation between moduli stabilization and inflationary dynamics is relaxed. The relaxation becomes more significant when we use the recently proposed D-term generated racetrack model

    Full Text Available Accidental radioisotope burns are rare. The major components of radiation injury are burns, interstitial pneumonitis, acute bone marrow suppression, acute renal failure and adult respiratory distress syndrome. Radiation burns, though localized in distribution, have systemic effects, and can be extremely difficult to heal, even after multiple surgeries. In a 25 year old male who sustained such trauma by accidental industrial exposure to Iridium192 the early presentation involved recurrent haematemesis, pancytopenia and bone marrow suppression. After three weeks he developed burns in contact areas in the left hand, left side of the chest, abdomen and right inguinal region. All except the inguinal wound healed spontaneously but the former became a non-healing ulcer. Pancytopenia and bone marrow depression followed. He was treated with morphine and NSAIDs, epidural buprinorphine and bupivicaine for pain relief, steroids, antibiotics followed by wound excision and reconstruction with tensor fascia lata(TFL flap. Patient had breakdown of abdominal scar later and it was excised with 0.5 cm margins up to the underlying muscle and the wound was covered by a latissimis dorsi flap. Further scar break down and recurrent ulcers occurred at different sites including left wrist, left thumb and right heel in the next two years which needed multiple surgical interventions.

    Bone marrow aplasia is one of the main syndromes following a high dose accidental radiation exposure. Although both transfusion and bone marrow transplantation have been used with some success since the first treatments of patients, other therapeutic strategies are needed. New promising approaches of the treatment of aplasia have appeared with the development of experimental and clinical hematology. Some new trends for the treatment of the hematopoietic injury based on bone marrow transplantation rely on new sources of compatible donor cells, such as cord blood, on the selection of immature haemopoietic cells and on new transplant regimens. The hematopoietic growth factors stimulate proliferation and/or differentiation of hematopoietic progenitors and possibly stem cells. Furthermore, they act on the functions of mature cells. They have now specific uses in hematology, related to their role in the regulation of growth and differentiation of hematopoietic progenitor cells. Some growth factors have already been used for the treatment of accidental radiation-induced aplasia and lessons have been learned from their medical management and follow-up. (author) 30 refs.

    1997-12-31

    The requirements for protective clothing against accidental immersion are discussed and the advantages and limitations of the main types of immersion protection available are analysed. The variety of designs available reflects the various circumstances under which they may be used. In broad terms in the offshore industry these include the following activities: normal work without risk of immersion but with a possible need to abandon the rig or ship; work in areas where there is risk of accidentally falling into the sea; flying over the sea in a helicopter. The first response to sudden immersion in sea water, which must usually be considered to be cold, is a sudden gasp often followed by an immediate phase of uncontrolled breathing. Since control of ones breathing between and under the breaking waves is essential to staying alive, this is a critical time. After surviving this initial ``cold shock`` phase, the effects of body heat loss become hazardous. Protection against hypothermia has been the priority for those providing survival suits and protective clothing while the hazard of the immediate response to cold immersion has been unrecognised to a large extent.

    Brake cleaner liquid is commonly used for cleaning of engines and motor parts. The commercially available products usually contain mainly volatile organic compounds. As a consequence brake cleaner evaporates fast and almost completely from the cleaned surface. This case report presents a fatal accidental inhalation of brake cleaner liquid aerosols due to the attempted cleaning of a boat engine. A 16year old boy was found lifeless in the engine compartment of a boat engine. In close proximity to the body, the police found cleanings wipes soaked with brake cleaner as well as a pump spray bottle filled with brake cleaner. Essentially the autopsy revealed a cerebral oedema with encephalomalacia, no coagulated blood as well as increased blood and tissue fluid content of the lung. Toxicological analysis revealed brake cleaner fluid in the lung, gastric content and heart blood. Copyright © 2018 Elsevier B.V. All rights reserved.

    Accidental detection of an asymptomatic apical periodontitis raises the question whether this lesion should be treated or not. Arguments favouring treatment are that the inflammation may cause pain in the future, may enlarge or may negatively affect the host's resistance. Reasons for not treating may be that treatment weakens the tooth, may cause iatrogenic damage and that treatment is expensive and burdensome for the patient and does not lead in all cases to complete healing. Scientific evidence supporting either choice, whether treating the lesion or not, is lacking. In making such decisions, therefore, personal judgments by the patient and the dentist concerning the impact on the quality of life of the patient play an important role.

  5. Is the tri-bimaximal mixing accidental?

    Abbas, Mohammed

    2010-01-01

    The Tri-bimaximal (TBM) mixing is not accidental if structures of the corresponding leptonic mass matrices follow immediately from certain (residual or broken) flavor symmetry. We develop a simple formalism which allows one to analyze effects of deviations of the lepton mixing from TBM on structure of the neutrino mass matrix and on underlying flavor symmetry. We show that possible deviations from the TBM mixing can lead to strong modifications of the mass matrix and strong violation of the TBM mass relations. As a result, the mass matrix may have an "anarchical" structure with random values of elements or it may have some symmetry which differs from the TBM symmetry. Interesting examples include matrices with texture zeros, matrices with certain "flavor alignment" as well as hierarchical matrices with a two-component structure, where the dominant and sub-dominant contributions have different symmetries. This opens up new approaches to understand the lepton mixing.

    Full Text Available How do we define, discuss or assess aesthetics within a contemporary philosophical framework? The indefiniteness that accompanies attempts to formalize a definition of the aesthetic is a primary focus of this paper. This lack of a definition has occupied philosophers for hundreds of years in attempts to delineate the boundaries of an elusively formless concept. This formlessness speaks to the incredibly evasive character of such a pervasive feature recognized in both natural and artificial systems, agents and artefacts. With the rapid growth of artificially intelligent systems and an astounding diversity in computational creativity, in what ways may we approach aesthetics? How is the aesthetic recognized, determined and produced? This paper seeks to critically engage issues of non-human agency, inter-object relations, and aesthetic theory in relation to computational entities and autonomous systems. The ability of these systems to operate outside of human cognitive limitations including thought patterns and constructions which may preclude alternative aesthetic outcomes, afford them in some ways limitless potential in relation to aesthetics. The designation of the accidental or provisional is utilized as an alternative approach to the production and assessment of aesthetic occurrences of the non-human.

  14. Dose assessment under incidental and accidental conditions

    International Nuclear Information System (INIS)

    Huebschmann, W.G.

    1988-01-01

    Dose assessment for the licesing process of a nuclear power plant covers the routine release of radioactive substances into the atmosphere as well as releases due to incidents. Source terms for these incidents are evaluated by the detailed incident analysis of the plant. The types of incidents to be covered are determined in the FRG by the ''Stoerfall-Leitlinien'' of the Ministry of the Interior. The calculation of dose equivalents in the environment of the plant differs from the calculation of doses due to routine releases, as incidents are single events occuring at undeterminate time, and the results must be conservative. Some details are being described. During the operation of the plant it is essential to measure not only the radioactivity release rates but also the necessary meteorological parameters for the instantaneous determination of the atmospheric dispersion in case of incidental or accidental releases of radioactivity. This instantaneous assessment assists in taking measurements of ground contamination and in deciding about countermeasures for the protection of plant personnell and population. (author) [pt

    Hydroxychloroquine is an oral antimalarial medication commonly used off-label for a variety of rheumatological conditions, including systemic lupus erythematosus, rheumatoid arthritis, Sjögren's syndrome and dermatomyositis. We present a case of a 64-year-old woman who presented with acute onset headache, bilateral tinnitus, and left-sided facial numbness and tingling in the setting of accidentally overdosing on hydroxychloroquine. By the next morning, the patient began to experience worsening in the tingling sensation and it eventually spread to her left arm, thigh and distal extremities. The patient also complained of new onset blurring of her peripheral vision and feeling 'off balance.' Despite a complete neurological and ophthalmological work-up with unremarkable imaging and blood work, the patient has had no improvement in her tinnitus, left-sided paresthesias, visual disturbance or ataxia. This is a unique case of hydroxychloroquine overdose resulting in permanent neurotoxic vestibulopathy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Removal half-life (RHL) of tritium is one of the best means for optimising medical treatment, reduction of committed effective dose (CED) and quick/easy handling of a large group of workers for medical treatment reference. The removal of tritium from the body depends on age, temperature, relative humidity and daily rainfall; so tritium removal rate, its follow-up and proper data analysis and recording are the best techniques for management of accidental acute tritium exposed cases. The decision of referring for medical treatment or medical intervention (MI) would be based on workers' tritium RHL history taken from their bodies at the facilities. The workers with tritium intake up to 1 ALI shall not be considered for medical treatment as it is a derived limit of annual total effective dose. The short-term MI may be considered for tritium intake of 1-10 ALI; however, if the results show intake ≥100 ALI, extended strong medical/therapeutic intervention may be recommended based on the severity of exposure for maximum CED reduction requirements and annual total effective dose limit. The methodology is very useful for pressurized heavy water reactors (PHWRs) which are mainly operated by Canada and India and future fusion reactor technologies. Proper management will optimise the cases for medical treatment and enhance public acceptance of nuclear fission and fusion reactor technologies. (authors)

    The global context of my PhD thesis work is the optimization of air pollution monitoring networks, but more specifically it concerns the monitoring of accidental releases of radionuclides in air. The optimization problem of air quality measuring networks has been addresses in the literature. However, it has not been addresses in the context of surveillance of accidental atmospheric releases. The first part of my thesis addresses the optimization of a permanent network of monitoring of radioactive aerosols in the air, covering France. The second part concerns the problem of targeting of observations in case of an accidental release of radionuclides from a nuclear plant. (author)

  9. Lessons learned from accidental exposures in radiotherapy

    International Nuclear Information System (INIS)

    2000-01-01

    The medical use of radiation is unique in that patients are intentionally exposed to radiation. The aim in radiation therapy is twofold: to deliver a dose and dose distribution that is adequate for tumour control, but which also minimizes complications in normal tissues. In therapeutic applications, the doses are high and a deviation from the prescribed dose may have severe or even fatal consequences. There is therefore a great need to ensure adequate radiation protection and safety in radiotherapy by verifying that all personnel involved are appropriately trained for their duties, that the equipment used meets relevant international specifications for radiation safety and that safety culture is embedded in routine activities in radiotherapy departments. Many individuals must interact and work together on highly technical measurements and calculations, and therefore the potential for mistakes is great. A review of the mistakes shows that most are due to human error. The International Basic Safety Standards for Protection against Ionizing Radiation and the Safety of Radiation Sources (IAEA Safety Series No. 115) require that a prompt investigation be conducted whenever an accidental medical exposure of patients occurs. The report of the investigation is to be disseminated to the appropriate parties so that lessons can be learned to prevent similar accidents or mitigate their consequences in the future. This Safety Report is a collection of a large number of events that may serve as a checklist against which to test the vulnerability of a facility to potential accidents, and to provide a basis for improving safety in the use of radiation in medical applications. A further purpose of this report is to encourage readers to develop a questioning and learning attitude, adopt measures for the prevention of accidents, and prepare for mitigation of the consequences of accidents if they occur

    Planning and organisation, as well as actions taken during accidental discharging of hazardous substances (hydrocarbons) into the soil and water, show that without integrating all the functions of safety, occupational safety, fire and explosion protection, technical safety, all the way to the environmental protection, procedure of cleaning, rehabilitation and remediation of polluted areas into their original state cannot be successfully carried out. Neglecting any of the mentioned links/components of the procedure represents a risk to people's health and life, while pollution to the environment remains a constant threat. Development of technologies is quickly transforming the environment in which the professionals of all disciplines work. Therefore, the response to changes by application of new technologies and procedures in all domains is indispensable, however, through a comprehensive and expert perception and consideration of each of the essential correlations comprising the safety management in all the fields. Through management of safety projects in environmental protection, it has become obvious that a united management of different fields is necessary, as well as management of safety in general. Engineering, health, legislation, public, environmental standards, occupational safety, hazards, biophysical and socio-economic aspects are parts of an integral management. Experts joined efforts through interaction and communications are inter-disciplinary characteristics, i.e. multi-disciplinary safety management, but also the management of each project separately. Exactly this knowledge exchange is highly productive and becomes an indispensable element in recognition of indirect and cumulative actions, thus applicable in any field. Implementation of European standards and accreditation of procedures pursuant to the corresponding standards, from risk assessment through rehabilitation to independent expert confirmation of efficiency in implementing the entire

    In this paper the relationship between accidental worldsheet symmetries of the string generating functional and target space invariance groups is discussed. Accidental symmetries are used to derive the invariance groups and effective low energy Lagrangian for the bosonic string, and the heterotic string compactified to four-dimensions on Z N orbifolds. The necessity of a new type of Green-Schwarz mechanism, associated with the auxiliary vector field in the four-dimensional N = 1 supergravity multiplet, is shown using these methods

    Reports on accidental auto-injection of adrenaline are few. We encountered three cases of accidental injection of adrenaline. In this study, we have examined and reported the clinical courses and symptoms of our cases. CASE 1 involved a female physician in her 50s who had attended an explanatory meeting on auto-injection of adrenaline. She mistook EpiPen® to be the EpiPen trainer and accidentally injected herself with 0.3 mg EpiPen®. Her systolic/diastolic pressure peaked at 7 min to reach 144/78 mmHg and decreased to 120/77 mmHg at 14 min. Except for palpitation after 7 min, the only subjective symptom was local pain at the injection site. CASE 2 was noted in a 6-year-old boy. He accidentally pierced his right forefinger with 0.15 mg EpiPen®, and after 20 min, his right forefinger was swollen. The swelling improved 80 min after the accidental injection. CASE 3 was noted in a 4-year-old girl. She accidentally injected herself with 0.15 mg EpiPen®. Her systolic/diastolic pressure peaked at 23 min to reach 123/70 mmHg and decreased to 96/86 mmHg at 28 min. Severe adverse effects of accidental auto-injection of adrenaline were not observed in these three cases. Our findings suggest that while handling adrenaline auto-injectors, we should keep in mind the possibility of accidental injection.

    Lack of awareness and recognition of child maltreatment is the major reason behind underreporting. All victims often interact with the health care system for routine or emergency care. In several research works, non-accidental fractures are the second most common injury in maltreated children and it is represented up to one-third of cases. To determine the incidence of different types of accidental and non-accidental skeletal injuries among children, estimate the severity of injuries according to the modified injury severity score and to determine the degree of fractures either closed or opened (Gustiloe-Anderson open fracture classification). Moreover, identifying fractures resulting from child abuse and neglect. This aimed for early recognition of non-accidental nature of fractures in child maltreatment that can prevent further morbidity and mortality. A descriptive study was carried out on all children (109) with skeletal injuries who were admitted to both Main Alexandria and El-Hadara Orthopedic and Traumatology University Hospitals during six months. History, physical examination and investigations were done for the patients. A detailed questionnaire was taken to diagnose child abuse and neglect. Gustiloe-Anderson open fracture classification was used to estimate the degree of open fractures. Out of 109 children, twelve cases (11%) were categorized as child maltreatment. One case was physical abuse, eight cases (7.3%) were child neglect and three cases (2.8%) were labour exploitation. Road traffic accidents (RTA) was the commonest cause of skeletal injuries followed by falling from height. Regarding falls, they included 4 cases of stair falls in neglected children and another four cases of falling from height (balcony/window). The remaining 36 cases of falls were accidental. The skeletal injuries were in the form of fractures in 99 cases, dislocation in two cases, both fracture and/or dislocation in three cases, and bone deformity from brachial plexus injury

The management of patients exposed to large doses of radiation is constantly improving because of increasing ability to prevent and treat infection and to control haemorrhage. The possible effectiveness of temporary bone marrow grafts offers promise of a further reduction in mortality. The use of this growing biological information is closely related to, and to a large extent dependent upon, improvements in physical dosimetry for radiation accidents. (author) [French] Des accidents provoques par les rayonnements continuent a se produire de temps a autre et il ne semble guere que l'on puisse esperer les eliminer entierement. Toutefois, le traitement des sujets exposes a de fortes doses de rayonnement ne cesse de s'ameliorer; on parvient, en effet, dans une mesure croissante a empecher et a traiter l*infection ainsi qu'a arreter l'hemorragie. Comme la greffe temporaire de la moelle des os semble devoir donner des resultats, on peut s*attendre a une nouvelle reduction du taux de mortalite. L'application de ces connaissances biologiques sans cesse accrues est fonction, dans une large mesure, des ameliorations apportees a la dosimetrie physique des accidents nucleaires. (author) [Spanish] De vez en cuando se siguen produciendo accidentes de irradiacion y las perspectivas de evitarlos por completo parecen ser bastante remotas. El tratamiento de las victimas expuestas a dosis elevadas de radiaciones mejora constantemente debido a la creciente posibilidad de prevenir y tratar las infecciones, y de controlar las hemorragias. Tambien es posible que la eficacia de ios injertos temporales de medula osea se traduzca en una disminucion de la mortalidad. El aprovechamiento de estos conocimientos biologicos cada vez mas amplios guarda una estrecha relacion con los perfeccionamientos en materia de dosimetria fisica en caso de accidentes de irradiacion.

    Full Text Available Las labores que se realizan en los proyectos de construcción son consideradas de alto riesgo al facilitar la ocurrencia de accidentes laborales que afectan la integridad física, mental y social de los colaboradores como la productividad de las empresas. Por tal motivo, el propósito de este artículo es analizar las causas y consecuencias de los accidentes laborales ocurridos durante el segundo semestre del año 2012 en dos proyectos de construcción de Neiva, Colombia. El alcance fue de tipo documental considerando como fuente de información los soportes de los accidentes laborales reportados ante la Administradora de Riesgo Laborales (ARL; para determinar las causas que dieron origen a dichos accidentes se utilizó el modelo de Frank E. Bird. Se analizaron 117 accidentes en los que se identificaron 195 faltas de control, 136 factores personales, 112 factores del trabajo, 151 actos inseguros y 54 condiciones inseguras; lo anterior teniendo en cuenta que en algunos accidentes se presentaron más de una causa. De esta manera se concluye que el mayor porcentaje de accidentes de trabajo, ha sido generado por faltas de control seguidos por actos inseguros. Por tal motivo se recomienda la realización de programas de gestión de riesgos prioritarios, basados en una adecuada identificación de peligros, que permitan mitigar y controlar los riesgos, desarrollando a la vez en los trabajadores una cultura de autocuidado

  1. Demonstration of the astral post accidental code

    . The results proposed by ASTRAL can in turn be saved in its database, on the user's request, in order to be processed by other tools such as Geographical Information Systems, which enable spatial analysis and map production. Such maps are very helpful in crisis situations to decision makers since by answering to questions of a 'where?' type, at a given time, they complete the information delivered by ASTRAL, which answers to questions of a 'when?' type, at a given site. This is why a link to ASTRAL has been constructed in CARTINFO, an IRSN tool dedicated to mapping results for its Crisis Technical Center. Thus the CONRAD, ASTRAL and CARTINFO softwares constitute a chain for IRSN's Crisis Technical Center, calculating transfers through the environment and consequences of an atmospheric accidental radionuclide release. The development of this version started in 1999 and has been subject to a quality assurance program. The identified customers and users have been associated in a control committee expressing needs, validating choices and checking the good progress of the project. The programming is currently being validated by test scenarios that check the equations, parameters, functionalities and navigation through the screens. The technology and architecture chosen for the second version of ASTRAL are different from the previous ones. It now uses an internet technology and is of a three-third type, the software requiring an Oracle database, a Microsoft web server and a consultation station. These choices offer important advantages: the spreading and maintenance of the tool are very easy. In fact, once the server and the database have been installed an a network, the users only need a web browser to run the code. The initial installation and the updating are thus no more to be made an every user station, but only on the server and/or the database; the code may be installed on a portable computer, which hosts the database, the internet server and the web browser.

    2014-01-01

    To test young children’s false belief theory of mind in a morally relevant context, two experiments were conducted. In Experiment 1, children (N = 162) at 3.5, 5.5, and 7.5 years of age were administered 3 tasks: prototypic moral transgression task, false belief theory of mind task (ToM), and an “accidental transgressor” task, which measured a morally relevant false belief theory of mind (MoToM). Children who did not pass false belief ToM were more likely to attribute negative intentions to an accidental transgressor than children who passed false belief ToM, and to use moral reasons when blaming the accidental transgressor. In Experiment 2, children (N = 46) who did not pass false belief ToM viewed it as more acceptable to punish the accidental transgressor than did participants who passed false belief ToM. Findings are discussed in light of research on the emergence of moral judgment and theory of mind. PMID:21377148

    1948-03-01

    Full Text Available En los tiempos antiguos no existía ley ni disposición alguna de carácter social que favoreciera a los trabajadores incapacitados por enfermedad o por accidente, por tanto, eran tratados como esclavos o considerados como animales. Los accidentes de trabajo y las enfermedades profesionales eran casi desconocidas antes de la introducción de la maquinaria en la industria, por lo cual no existía el derecho a indemnización por concepto de daños que sufriera el trabajador en el desempeño de sus labores. Solamente se conocen los edictos de Rotari (año 645 de la éra cristiana lanzados en Italia con el fin de reparar los accidentes de los obreros de la construcción y después, en la época del Renacimiento, algunas publicaciones que hablan de ciertas enfermedades de los trabajadores (Ellemborg 1473, Paracelso 1493-1541. Ya en la edad media la industria comenzó a tomar cierta importancia y dada la escasez de brazos, se vio obligado el patrón por fuerza de las circunstancias a prestar ayuda económica a los trabajadores incapacitados por una u otra causa. Los accidentes sucedidos en las industrias no se consideraban como de trabajo, por no conocerse el peligro que envolvía el empleo de la maqumana. En el siglo XVII y a principios del XVIII un médico italiano, Ramazzini habla del perjuicio que ocasionan ciertos trabajos en el organismo del individuo, produciendo alteraciones anatómicas y funcionales. Solamente a fines del siglo XVIII y a principios del XIX con la producción en masa, con el aumento del número de obreros y con la falta de protección, empezaron los accidentes de trabajo a hacerse notorios.

    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

    Full Text Available Dentro de los trabajos desarrollados al interior del grupo de investigación SES, se adelantan esfuerzos por el modelamiento de problemática social, encontrándose como uno de los principales ejes temáticos los riesgos laborales presentes en los trabajadores que realizan la actividad de pavimentación con asfaltos. Por ello, se adelantó una investigación tendiente a determinar las principales causas de accidentalidad en el trabajo y de riesgos profesionales para dichas actividades. De los resultados  obtenidos se comprueba dos verdades evidentes y es que la exigencia física del trabajo en la pavimentación genera una alta probabilidad de accidentalidad y una alta incidencia en los dolores de espalda, pero resulta interesante analizar el impacto sobre esta accidentalidad de variables como el impacto del estado civil y la afición a los deportes. En el primer caso se puede explicar por la edad como un correlator tanto de la edad como de las enfermedades respiratorias y en el segundo caso es mejor estimular la práctica de los deportes para evitar los problemas respiratorios en este tipo de industria.

    2008-01-01

    This book is a must-read for anyone responsible for projects and initiatives that span functional and geographical divides. Authors Moran and Youngdahl bring extensive experience and learning from industry practice to present a clear and straightforward treatment of the leadership skills and knowledge required to lead projects that are global in nature. They have written the first book of its kind to address the three essential skills of global project leaders - strategic project management, project leadership, and cross-cultural leadership. The authors argue that global project leadership is an essential skill in our project-based world and that we are all either intentional or accidental project leaders. Intentional project leaders pursue formal project management education and even certification whereas accidental project leaders find themselves leading global projects and initiatives as a result of a special assignment or promotion. Moran and Youndahl have found that the vast majority of global projects ...

  1. Food allergy: practical approach on education and accidental exposure prevention.

    Pádua, I; Moreira, A; Moreira, P; Barros, R

    2016-09-01

    Food allergies are a growing problem and currently the primary treatment of food allergy is avoidance of culprit foods. However, given the lack of information and education and also the ubiquitous nature of allergens, accidental exposures to food allergens are not uncommon. The fear of potential fatal reactions and the need of a proper avoidance leads in most of the cases to the limitation of leisure and social activities. This review aims to be a practical approach on education and accidental exposure prevention regarding activities like shopping, eating out, and travelling. The recommendations are focused especially on proper reading of food labels and the management of the disease, namely in restaurants and airplanes, concerning cross-contact and communication with other stakeholders. The implementation of effective tools is essential to manage food allergy outside home, avoid serious allergic reactions and minimize the disease's impact on individuals' quality of life.

    Artificial honeycomb lattices with Dirac cone dispersion provide a macroscopic platform to study the massless Dirac quasiparticles and their novel geometric phases. In this paper, a quadruple-degenerate state is achieved at the center of the Brillouin zone in a two-dimensional honeycomb lattice phononic crystal, which is a result of accidental degeneracy of two double-degenerate states. In the vicinity of the quadruple-degenerate state, the dispersion relation is linear. Such quadruple degeneracy is analyzed by rigorous representation theory of groups. Using method, a reduced Hamiltonian is obtained to describe the linear Dirac dispersion relations of this quadruple-degenerate state, which is well consistent with the simulation results. Near such accidental degeneracy, we observe some unique properties in wave propagating, such as defect-insensitive propagating character and the Talbot effect.

    Full Text Available The financial loss due to working accidents is very substantial, quite apart from the actual loss of human lives. Hence avoiding these accidents is a most important matter. The accident index in the various industries shows a rate of increase that is larger than should be the case in proportion to the development of the industries concerned, and the larger number of employees. The fact that these indexes are smaller in many countries, however, shows that these accidents can be considerably reduced if suitable measures are taken to avoid them. In chapter 2 of our magazine, issue no. 178, a variety of reasons were discussed that may originate accidents, although these causes are not directly linked to the accident itself. In this article mention is made of some of the measures that can be taken in the handling of cutting and welding equipment, and also of inflammable liquids, to prevent possible accidents.El peso de los accidentes de trabajo sobre la economía supone cantidades muy grandes que, independientemente del inestimable valor de una vida humana, realzan la importancia de la prevención de accidentes. Los índices de accidentes muestran en diferentes industrias un crecimiento mayor de lo que debería corresponder proporcionalmente, habida cuenta del crecimiento laboral. El hecho de que en distintos países los índices sean inferiores, demuestra que se pueden conseguir buenos frutos si se concede primordial importancia a que los trabajos se realicen con las debidas medidas de seguridad. En el Capítulo 2, número 178 de esta Revista, se detallaron diversas causas que pueden originar un accidente sin estar ligadas en forma directa con una tarea determinada. En el presente trabajo se indican algunas de las medidas que deben observarse en el manejo de los equipos de soldadura y corte, así como en el transvase de líquidos inflamables.

  9. Compact fluorescent lamp phosphors in accidental radiation monitoring

    The application of lamp phosphors for accidental dosimetry is a new concept. Since the materials used in fluorescent lamps are good photo luminescent materials, if one can either use the inherent defects present in the phosphor or add suitable modifiers to induce thermoluminescence (TL) in these phosphors, then the device (fluorescent lamp) can be used as an accidental dosemeter. In continuation of our search for a suitable phosphor material, which can serve both as an efficient lamp phosphor and as a good radiation monitoring device, detailed examination has been carried out on cerium and terbium-doped lanthanum phosphate material. A 90 Sr beta source with 50 mCi strength (1.85 GBq) was used as the irradiation source for TL studies. The TL response as a function of dose received was examined for all phosphors used and it was observed that the intensity of the TL peak vs. dose received was a linear function in the dose range 0.1-200 Gy in each case. Incidentally LaPO 4 :Ce,Tb is a component of the compact fluorescent lamp marketed recently as an energy bright light source. Besides having very good luminescence efficiency, good dosimetric properties of these phosphors render them useful for their use in accidental dosimetry also. (authors)

    Full Text Available El objetivo de este artículo es identificar el comportamiento de las muertes por accidentes de motocicleta y las variables relacionadas con la teoría de la reproducción social de Samaja, para el período 2000-2005 en el estado de Pernambuco, Brasil. Se realizó un estudio ecológico con abordaje caso-control. La unidad de análisis fue el municipio. Los casos fueron definidos considerando el 20% de los municipios con los mayores coeficientes bayesianos empíricos locales de mortalidad por accidentes de motocicleta y los controles, como el 40% de los municipios con menores coeficientes de mortalidad por accidentes de motocicleta. Los municipios con mayor probabilidad de altos coeficientes de mortalidad por accidentes de motocicleta mostraron factores de crecimiento poblacional altos, así como de crecimiento de la flota de vehículos, bajas densidades demográficas, bajo PBI per cápita, y más de 20 motocicletas por mil habitantes. Se concluye que las variables relacionadas a las macropolíticas mostraron una mayor fuerza para explicar las probabilidades de defunciones por accidentes de motocicleta.

    During reclaimed wastewater transportation under anaerobic conditions sulfide generation may take place, which should be avoided due to the numerous problems related to it. This is the case of the reclaimed wastewater reuse scheme of Tenerife, one of whose elements is a completely filled 61 km long gravity pipeline, 0,60 m in diameter. In order to avoid the appearance of anaerobic conditions a controlled nitrate dosage system has been designed to be installed at the pipeline inlet, with nitrate dosage to be controlled by the organic matter content of the reclaimed wastewater, using turbidity as an indicator of it.

    This article presents emergence control schemes implemented in the subsystem 1 (SS1) which makes part of the ANDE system. These schemes seek to maintain the system in operation when simple contingencies take place in one among the five circuits which compose the main transmission trunk. The reasons for their implementation are linked to the end of the transmission capacity and problem of reactive losses which support the system voltage, therefore producing a general voltage drop which can take to the undesirable phenomenon of system voltage collapse. The scheme replies to the overloads in emergency regimen, through the necessary load disconnections to reestablish the balance between the load and reduced transmission capacity using an automatic, quick and efficient way.

  20. Accidental outcomes guide punishment in a "trembling hand" game.

    Directory of Open Access Journals (Sweden)

    Fiery Cushman

    Full Text Available How do people respond to others' accidental behaviors? Reward and punishment for an accident might depend on the actor's intentions, or instead on the unintended outcomes she brings about. Yet, existing paradigms in experimental economics do not include the possibility of accidental monetary allocations. We explore the balance of outcomes and intentions in a two-player economic game where monetary allocations are made with a "trembling hand": that is, intentions and outcomes are sometimes mismatched. Player 1 allocates $10 between herself and Player 2 by rolling one of three dice. One die has a high probability of a selfish outcome, another has a high probability of a fair outcome, and the third has a high probability of a generous outcome. Based on Player 1's choice of die, Player 2 can infer her intentions. However, any of the three die can yield any of the three possible outcomes. Player 2 is given the opportunity to respond to Player 1's allocation by adding to or subtracting from Player 1's payoff. We find that Player 2's responses are influenced substantially by the accidental outcome of Player 1's roll of the die. Comparison to control conditions suggests that in contexts where the allocation is at least partially under the control of Player 1, Player 2 will punish Player 1 accountable for unintentional negative outcomes. In addition, Player 2's responses are influenced by Player 1's intention. However, Player 2 tends to modulate his responses substantially more for selfish intentions than for generous intentions. This novel economic game provides new insight into the psychological mechanisms underlying social preferences for fairness and retribution.

    Full Text Available Mepivacaine is a potent local anaesthetic and used for infiltration and regional anaesthesia in adults and pediatric patients. Intoxications with mepivacaine affect mainly the CNS and the cardiovascular system. We present a case of accidental intravenous mepivacaine application and intoxication of an infant resulting in seizure, broad complex bradyarrhythmia, arterial hypotension and finally cardiac arrest. The patient could be rescued by prolonged resuscitations and a rapid initiation of ECMO and survived without neurological damage. The management strategies of this rare complication including promising other treatment options with lipid emulsions are discussed.

  3. Radioactive releases into the environment under accidental conditions

    Although accidents involving the release of radioactive materials and the unplanned exposure of people can occur at any stage of the nuclear fuel cycle, most attention has been focused on reactor accidents. Although no power reactor accidents involving exposure of the public have yet occured, it should be recognized that the probability of such accidental releases cannot be reduced to zero. Since the inventory of radioactive materials in power reactors is very large, it is usual to postulate, for safety assessments, that a release of fission products takes place in spite of all protective measures. This postulated release is of importance for reactor siting and for preparing emergency plans. (HP) [de

    2015-12-01

    Although non-accidental injuries (NAI) are more common in cases of unexplained fractures than rare disorders such as osteogenesis imperfecta (OI), ruling out OI and other medical causes of fracture is always indicated. The majority of OI patients can be diagnosed with the help of family history, physical examination, and radiographic findings. In particular, there are a few radiological findings which are seen more commonly in NAI than in OI which may help guide clinician considerations regarding the probability of either of these diagnoses. At the same time, molecular testing still merits careful consideration in cases with unexplained fractures without obvious additional signs of abuse. © 2015 Wiley Periodicals, Inc.

    The shutter on one of the windows of an X-ray diffraction apparatus was accidentally left open, exposing the worker to the radiation. The worker was wearing a dosimeter film, which was processed immediately to evaluate the potential risk. It was determined that the exposure rate was 350 Roentgen/minute on the skin surface, with corrections being made for the worker's thin clothing. It was concluded that in spite of the worker receiving a relative high dose, it did not reach the threshold value for producing deterministic effects such as cataracts, erythema, and skin damage

    An improvement in a tritium control system based on a catalytic oxidation reactor is provided wherein accidental releases of tritium into room air are controlled by flooding the catalytic oxidation reactor with hydrogen when the tritium concentration in the room air exceeds a specified limit. The sudden flooding with hydrogen heats the catalyst to a high temperature within seconds, thereby greatly increasing the catalytic oxidation rate of tritium to tritiated water vapor. Thus, the catalyst is heated only when needed. In addition to the heating effect, the hydrogen flow also swamps the tritium and further reduces the tritium release

    One result of the workshop was, that even in the case of severe accident sequences in modern nuclear power plants (other facilities were not discussed), there will be enough time to take active measures in order to lower the emissions and to diminish the consequences inside and outside of the plant. On the whole, new evidence from Harrisburg show that previously estimated accidental emissions, especially of radiologically relevant nuclides, have been rather conservative and that much lower emissions are possible, if the above measures are considered. Under accident conditions, models to predict radiation exposure must be applied under the event of a short-term release. (orig./DG) [de

  11. Self-Administered Ethanol Enema Causing Accidental Death

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Excessive ethanol consumption is a leading preventable cause of death in the United States. Much of the harm from ethanol comes from those who engage in excessive or hazardous drinking. Rectal absorption of ethanol bypasses the first pass metabolic effect, allowing for a higher concentration of blood ethanol to occur for a given volume of solution and, consequently, greater potential for central nervous system depression. However, accidental death is extremely rare with rectal administration. This case report describes an individual with klismaphilia whose death resulted from acute ethanol intoxication by rectal absorption of a wine enema.

    At the present time the strength of the load-bearing members of VVER and fast reactors during a hypothetical accident is ordinarily investigated in model experiments [1]. A power burst during an accident is simulated by a nonnuclear exothermal reaction in water, which simulates the coolant and fills the model. The problem is to make the correct choice of the simulator of the accidental energy burst as an effective (i.e., sufficiently high working capacity) source of dangerous loads, corresponding to the conditions of an accident. What factors and parameters determine the energy release? The answers to these questions are contradictory

    Compressed air is being used extensively as a source of energy at industries and in daily life. A variety of fatal injuries are caused by improper and ignorant use of compressed air equipments. Many types of injuries due to compressed air are reported in the literature such as colorectal injury, orbital injury, surgical emphysema, and so on. Most of these injuries are accidental in nature. It is documented that 40 pounds per square inch pressure causes fatal injuries to the ear, eyes, lungs, stomach, and intestine. Openings of body are vulnerable to injuries by compressed air. Death due to compressed air injuries is rarely reported. Many cases are treated successfully by conservative or surgical management. Extensive survey of literature revealed no reports of fatal injury to the upper respiratory tract and lungs caused by compressed air. Here, we are reporting a fatal event of accidental death after insertion of compressed air pipe into the mouth. The postmortem findings are corroborated with the history and discussed in detail.

  15. Accidental Beam Losses and Protection in the LHC

    2005-01-01

    At top energy (proton momentum 7 TeV/c) with nominal beam parameters, each of the two LHC proton beams has a stored energy of 350 MJ threatening to damage accelerator equipment in case of accidental beam loss. It is essential that the beams are properly extracted onto the dump blocks in case of failure since these are the only elements that can withstand full beam impact. Although the energy stored in the beams at injection (450 GeV/c) is about 15 times smaller compared to top energy, the beams must still be properly extracted in case of large accidental beam losses. Failures must be detected at a sufficiently early stage and initiate a beam dump. Quenches and power converter failures will be detected by monitoring the correct functioning of the hardware systems. In addition, safe operation throughout the cycle requires the use of beam loss monitors, collimators and absorbers. Ideas of detection of fast beam current decay, monitoring of fast beam position changes and monitoring of fast magnet current changes are discussed, to provide the required redundancy for machine protection

    Full Text Available Recently, the veterinarians are dealing with a number of cases that require forensic expertise. Such a circumstance could be the accidental electrocution in animals, one of the causes of unnatural death. There is a scarcity with reference to the pathological findings in veterinary forensic medicine. In this paper, we present the main lesions that occurred in a horse with accidental electrocution that was presented for complete necropsy survey. A horse corpse was sent to the Pathology Department (Faculty of Veterinary Medicine, Cluj-Napoca, Romania for a full medical survey. Preliminary results and external examination: the body was in rigor mortis; from the nasal cavities drained out reddish foam and in the mouth was observed the presence of ingested feed (straw that was not chewed, suggesting a quick death. The findings detected after internal examination of the carcass were poor blood coagulability, haemorrhagic diathesis throughout the body, with haemorrhages of various sizes in different body regions (e.g., muscles of the withers, in the gluteal muscle, the mucosa of epiglottis, larynx, trachea, in the interstitium of the lung, and ecchymosis in the left kidney. Some other lesions detected were infarcts and haemorrhages in the fundic region of the stomach’s mucosa. In electrocution, haemorrhages are most often located in the respiratory tract, aspect observed in our case too. However, the diagnosis of electrocution has to corroborate the necropsy findings (which are not specific, with some other data such as the fulminant death and inspection of power source.

    Full Text Available En España se han puesto en marcha diferentes medidas de intervención con el objeto de modificar la práctica de los conductores de vehículos de motor, sin embargo no se ha observado una tendencia descendente ni en la tasa de accidentes de tráfico ni en el número de víctimas relacionadas con los mismos. Este articulo se plantea el interrogante de si las medidas tomadas para reducir el número de víctimas por accidente de tráfico se han dirigido realmente hacia las causas responsables de esa tendencia.

    Full Text Available En España se han puesto en marcha diferentes medidas de intervención con el objeto de modificar la práctica de los conductores de vehículos de motor, sin embargo no se ha observado una tendencia descendente ni en la tasa de accidentes de tráfico ni en el número de víctimas relacionadas con los mismos. Este articulo se plantea el interrogante de si las medidas tomadas para reducir el número de víctimas por accidente de tráfico se han dirigido realmente hacia las causas responsables de esa tendencia. Utilizando diversas fuentes de datos se observa que en España al comienzo de los años noventa se produjo una importante reducción de la tasa de accidentes de tráfico y sus consecuencias, pero en la segunda mitad de la misma década el incremento en la tasa de lesiones por accidentes de tráfico fue similar al producido en los años ochenta.

    Full Text Available Fodor ha argumentado a favor de un par de tesis que pueden caracterizarse como constituyendo un dilema: Por un lado, si adoptamos una teoría funcional para los conceptos explicamos semánticamente los casos Frege pero caemos en el holismo semántico. Por otro lado, si adoptamos una teoría causal/informacional evitamos el holismo pero no explicamos los casos Frege semánticamente. Fodor (por ej, 1994, 1998 y 2008 intenta evitar la segunda parte del dilema argumentando que los casos de Frege pueden tener una explicación sintáctica y no semántica. En este trabajo intentaré ofrecer una salida alternativa al dilema fodoriano. Propondré una explicación semántica de los casos Frege que incorpora tanto elementos de una teoría causal como de una de rol funcional. Afirmaré que el contenido cognitivo o estrecho de un concepto (el tipo de contenido aparentemente exigido por los casos Frege es el conjunto de contenidos causales/informacionales de las representaciones que figuran en su rol funcional. Considero que individuar a las representaciones en los roles por medio de sus contenidos causales permite evitar el holismo (evitando el proceso de ramsificación típicamente empleado para individuar a los roles y que identificar el contenido cognitivo con contenidos causales/informacionales de las representaciones en los roles permite evitar el referencialismo de las propuestas causales (podemos distinguir sentido de referencia en términos causales.

    AIM: To evaluate the type and nature of head injuries sustained by children under the age of 5 years who present to a busy accident and emergency (A and E) department following an accidental fall. MATERIALS AND METHODS: This study included all children under the age of 5 years, who over an 8-month period were referred to our A and E Department with head injury following an accidental fall. Data were collected regarding the height of the fall, whether or not stairs were involved, the type of surface that the child landed on and the height of the child. This was correlated with any soft-tissue injury or skull fracture. RESULTS: A total of 72 children (aged 4 months to 4.75 years) fulfilled all the criteria for an accidental fall. The heights of the falls ranged from less than 50 cm to over 3 m, with the majority below 1 m. Of the falls, 49 were onto a hard surface and 23 were onto a soft surface. Of the 72 children, 52 had visible evidence of head injury, 35 (71%) of 49 being the result of falls onto hard surfaces and 17 (74%) of 23 onto soft (carpeted) surfaces. There was no significant difference in the type of surface that resulted in a visible head injury. A visible head injury was seen in all children who fell from a height of over 1.5 m and in 95% of children who fell over 1 m. Of the 72 children, 32 (44%) had skull radiographs performed in accordance with established guidelines and 4 (12.5%) were identified as having a fracture. Of the 3 linear parietal fractures 2 were inflicted by falls of just over 1 m (from a work surface) and 1 by a fall of 80 to 90 cm onto the hard-edged surface of a stone fire surround. The 4th was a fracture of the base of skull following a fall from more than 3 m (from a first-storey window). CONCLUSIONS: In the vast majority of domestic accidents children do not suffer significant harm. Skull fractures are rare and probably occur in less than 5% of cases. To cause a skull fracture the fall needs to be from over 1 m or, if from a

    Full Text Available The study presented in this article describes a modern modeling methodology of the propagation of accidental flood waves in case a dam break; this methodology is applied in Romania for the first time for the pilot project „Breaking scenarios of Poiana Uzului dam”. The calculation programs used help us obtain a bidimensional calculation (2D of the propagation of flood waves, taking into consideration the diminishing of the flood wave on a normal direction to the main direction; this diminishing of the flood wave is important in the case of sinuous courses of water or with urban settlements very close to the minor river bed. In the case of Poiana Uzului dam, 2 scenarios were simulated with the help of Ph.D. Eng. Dan Stematiu, plausible scenarios but with very little chances of actually producing. The results were presented as animations with flooded surfaces at certain time steps successively.

    1996-01-01

    Seven different methods were used to estimate the dose rate to a female worker who was accidentally exposed in the neutron PHOENIX beamline at the IPNS. Theoretical and measured entrance dose rates ranged from 550 mrem/min to 2,850 mrem/min. Theoretical estimates were based on a Monte Carlo simulation of a spectrum provided by IPNS (Crawford Spectrum). Dose measurements were made with TLDs on phantoms and with ionization chambers in a water phantom. Estimates of the whole body total effective dose equivalent (TEDE) rate ranged from 5.2 mrem/min to 840 mrem/min. Assumed and measured quality factors ranged from 2.6 to 11.8. Cytogenic analyses of blood samples detected no positive exposure. The recommended TEDE rate was 158 mrem/min. The TEDE was 750 mrem

    A summary is given of the findings detailed in the most recent of a series of radiological studies of a liquid metal-cooled fast breeder reactor (Kelly, G.N. Simmonds, J.R. Smith, H. and Stather, J.W., The radiological consequences of notional accidental releases of radioactivity from fast breeder reactors: sensitivity to the dose-effect relationships adopted for early biological effects, Harwell, National Radiological Protection Board, NRPB-R87. London, HMSO (1979)). The results have indicated those areas where effort might be most profitably directed to improve the reliability of the predicted consequences. The composition of the released activity has been shown to have a marked influence on the sensitivity of the predicted consequences, and application of simple supportive medical treatment has a potential for reducing the predicted consequences by factors of up to an order of magnitude, depending on the composition of the release.

    Loss-of-function mutations in the gene SCN5A can cause Brugada syndrome (BrS), which is an inherited form of idiopathic ventricular fibrillation. We report the case of a 46-year-old patient, with no previous medical history, who had ventricular fibrillation after accidental inhalation of gasoline vapors. His electrocardiogram (ECG) showed a typical type-1 BrS pattern that persisted after the acute event. Genetic investigations allowed the identification of a novel SCN5A mutation leading to a frame-shift and early termination of the channel protein. Biochemical and cellular electrophysiology experiments confirmed the loss-of-function of the mutant allele. The patient was implanted with a cardioverter/defibrillator.

    Full Text Available Background. A case of accidental poisoning with autumn crocus (Colchicum autumnale that was misinterpreted for wild garlic (Allium ursinum is presented. Both plants grow on damp meadows and can be easily wrongly identified especially before blooming period as they have similar, pointed leaves.Results. Considering anamnestic data, clinical picture and laboratory findings in 43-yr-old female, a poisoning with the colchicine plant alkaloid was suspected. Later, it was confirmed by toxicology analyses (chromatography and spectrometry of the collected serum and urine samples. Severe initial gastrointestinal disorders progressed into ileus, bone-marrow suppression and multi-organ failure.Conclusions. After the patient had received a symptomatic treatment with granulocyte-directed growth factor and a suitable antibiotic therapy for secondary infection, she recovered within three weeks from the onset of condition. The most persistent problem was alopecia. The disease did not entailed any permanent sequellae which was confirmed 3 years after the patient was considered cured.

    Full Text Available Formalin is a hazardous chemical that needs cautious handling and special storage. Owing to its disinfectant and fixative (i.e. for preserving pathologic tissue specimens in histopathology properties, it is widely used in dentistry. Although, the terms formaldehyde and formalin are often confused as being identical, these are different as to the concentrations of the primary component i.e. formaldehyde. In fact, the common fixative available as 10% neutral buffered formalin is actually a 4% solution of formaldehyde (i.e., a 10% solution made from a 37-40% commercially pure formaldehyde solution. This case report describes an unfortunate case of accidental injection instead of local anesthetic, of formalin into the pterygomandibular space in a 35-year old woman during inferior alveolar nerve block for surgical removal of impacted lower right third molar and its successful management by cautious debridement (under both local and general anesthesia and empirical drug therapy (utilizing analgesics and antibiotics.

    In the present paper we present the consequences of an accidental occupational radiation exposure at a local hospital in Buenos Aires. Control at a local radiology service showed the lack of correct shielding in the X-ray equipment. The physicians and technicians (14 persons) exposed to radiation during 12 months were examined. The survey shows that: a) In 11 out of 14 radiation-exposed patients nodular goiter developed and an additional patient had diffuse goiter which means a goiter incidence of 85.7%; b) In 5 of the nodular goiter patients an increase in the size or the appearance of new nodules was observed along the follow-up period. No cancer was detected by FNA; c) Hypothyroidism was observed in 3/14 patients, and an additional patient had an abnormal TRH-TSH test, suggesting subclinical hypothyroidism; and d) Increased circulating antithyroid antibodies were found in one of the hypothyroid patients

    2012-02-10

    The investigation of uncertain fatalities requires accurate determination of the cause of death, with assessment of all factors that may have contributed to it. Gasoline is a complex and highly variable mixture of aliphatic and aromatic hydrocarbons that can lead to cardiac arrhythmias due to sensitization of the myocardium to catecholamines or acts as a simple asphyxiant if the vapors displace sufficient oxygen from the breathing atmosphere. This work describes a sudden occupational fatality involving gasoline. The importance of this petroleum distillate detection and its quantitative toxicological significance is discussed using a validated analytical method. A 51 year-old Caucasian healthy man without significant medical history was supervising the repairs of the telephone lines in a manhole near to a gas station. He died suddenly after inhaling gasoline vapors from an accidental leak. Extensive blistering and peeling of skin were observed on the skin of the face, neck, anterior chest, upper and lower extremities, and back. The internal examination showed a strong odor of gasoline, specially detected in the respiratory tract. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame ionization detector and confirmation was performed using gas chromatography-mass spectrometry. Disposition of gasoline in different tissues was as follows: heart blood, 35.7 mg/L; urine, not detected; vitreous humor, 1.9 mg/L; liver, 194.7 mg/kg; lung, 147.6 mg/kg; and gastric content, 116,6 mg/L (2.7 mg total). Based upon the toxicological data along with the autopsy findings, the cause of death was determined to be gasoline poisoning and the manner of death was accidental. We would like to alert on the importance of testing for gasoline, and in general for volatile hydrocarbons, in work-related sudden deaths involving inhalation of hydrocarbon vapors and/or exhaust fumes.

    Full text: A portable TLD measuring system was constructed at the J. Stefan Institute many years ago, motivated by the thread of a catastrophic nuclear event. It was designed for fast measurements in accidental dosimetry mainly for military and civil protection use. The system consists of a robust portable measuring unit built for measurements in field conditions, sized about 40 cm in diameter and weighting 5 kg. Dosimeters are based on CaF 2 :Mn ceramic tablets closed in water resistant plastic housings. In original design producer assured measuring range from cGy to kGy. Specially designed energy compensating filters are used to satisfy requirements for energy response from 0,1 to 3 MeV. Stability of readings is maintained with the temperature stabilized light source. Measuring time for manually driven heating-reading cycle of one dosimeter is about 30 sec. Many systems of the type with sets of dosimeters were stored unused for some years in depositories of different institutions. Modernization of equipment in last years raised questions of applicability of such measurement systems for contemporary needs. The system was thus tested in a secondary standards dosimetry laboratory for compliance with up to date requirements for accidental individual monitoring. Dosimeter characteristics as repeatability, linearity and directional response were of particular interest. As a result of the tests, technical improvements are suggested to extent systems measuring capabilities in order to meet new standards. Possibilities of its use in different fields of dosimetry are discussed, where quick in field measurements of high doses is required as for example in medicine or in civil protection motivated by the new threads of terrorist attacks.

    2005-12-01

    Finland with four other countries participated in the European Union's network project FARMING in 2000 - 2004. The aim of the project was to invite participants from each country representing the food supply chain in a stakeholder group and advance with the groups the networking in building preparedness for accidental contamination of the food production systems. The task of the groups was to evaluate the practicability of management options suggested for reduction of radiation exposure through foodstuffs, and for disposal of waste generated in implementation of these options. The criteria for practicability were effectiveness in reduction of radiation exposure through foodstuffs, technical feasibility, capacity, costs for implementation, secondary costs for waste disposal, socio-economic impact, and acceptability concerning ecology and protection of environment and landscape. Practicable management options aimed at sustainable restoration of food production systems after accidental contamination. The Finnish stakeholder group represented farm production, processing industry, food marketing, catering, advisor organisations for households and agriculture, consumers, nature conservation, the media, experts on environmental impact and authorities responsible for production, safety and security of foodstuffs, food supply and feedstuffs. The group was expected to examine the effect of the Finnish, and, also more generally, northern production conditions on the practicability of the suggested management options. The stakeholder group members first familiarized themselves with intervention after accidental contamination of a large milk production area and thereafter with practicability of individual management options. The evaluation was based on the group members' complementary expertise that very well covered the chain 'from field to fork' whether the issue was related to legislation, production methods, logistics, environmental impacts, or the issues of consumers and

Mobilizing patients on the first postoperative day, we observed no durotomy-associated complications. Conclusions. The frequency of accidental durotomies in MIS TLIF is low, with overweight being a risk factor for accidental durotomies. The minimally invasive approach seems to minimize durotomy-associated complications (CSF leakage, pseudomeningocele because of the limited dead space in the soft tissue. Patients with accidental durotomy can usually be mobilized within 24 hours after MIS TLIF without increased risk. The minimally invasive TLIF technique might thus be beneficial in the prevention of postoperative immobilization-associated complications such as venous thromboembolism. This trial is registered with DRKS00006135.

    Full Text Available Este trabajo analiza si las tarifas que se aplican para la determinación del denominado capital coste de pensiones derivadas de los accidentes de trabajo y enfermedades profesionales son las adecuadas. A partir de los datos de la Muestra Continua de Vidas Laborales y de la evolución de la longevidad de la población general en España, se estiman tablas de mortalidad para las contingencias de viudedad e invalidez que, combinadas con los parámetros económicos y financieros apropiados, permiten construir las bases técnicas actuarialmente justas para cada uno de los años objeto de análisis. Los resultados obtenidos sugieren que las tarifas aplicadas en el periodo 2011-2014 han sido muy superiores a las que se deberían haber aplicado, lo que habría originado una transferencia encubierta de recursos de las Mutuas Colaboradoras de la Seguridad Social hacia la Tesorería General de la Seguridad Social. Se concluye que es urgente articular un procedimiento de revisión periódica anual que adapte los elementos fundamentales de la tarifa a las cambiantes condiciones financieras, económicas y demográficas.

    Full Text Available Abstract Background Accidental poisoning is one of the leading causes of injury in the United States, second only to motor vehicle accidents. According to the Centers for Disease Control and Prevention, the rates of accidental poisoning mortality have been increasing in the past fourteen years nationally. In Texas, mortality rates from accidental poisoning have mirrored national trends, increasing linearly from 1981 to 2001. The purpose of this study was to determine if there are spatiotemporal clusters of accidental poisoning mortality among Texas counties, and if so, whether there are variations in clustering and risk according to gender and race/ethnicity. The Spatial Scan Statistic in combination with GIS software was used to identify potential clusters between 1980 and 2001 among Texas counties, and Poisson regression was used to evaluate risk differences. Results Several significant (p Conclusion The findings of the present study provide evidence for the existence of accidental poisoning mortality clusters in Texas, demonstrate the persistence of these clusters into the present decade, and show the spatiotemporal variations in risk and clustering of accidental poisoning deaths by gender and race/ethnicity. By quantifying disparities in accidental poisoning mortality by place, time and person, this study demonstrates the utility of the spatial scan statistic combined with GIS and regression methods in identifying priority areas for public health planning and resource allocation.

    Patients frequent take acetaminophen to treat dental pain. One previous study found a high rate of overuse of nonprescription analgesics in an emergency dental clinic. The purpose of this study is to determine if patients with dental pain are more likely to be treated for accidental acetaminophen poisoning than patients with other types of pain. We conducted a case-control study at 2 urban hospitals. Cases were identified by chart review of patients who required treatment for accidental acetaminophen poisoning. Controls were self-reported acetaminophen users taking therapeutic doses identified during a survey of emergency department patients. For our primary analysis, the reason for taking acetaminophen was categorized as dental pain or not dental pain. Our primary outcome was the odds ratio of accidental overdose to therapeutic users after adjustment for age, sex, alcoholism, and use of combination products using logistic regression. We identified 73 cases of accidental acetaminophen poisoning and 201 therapeutic users. Fourteen accidental overdose patients and 4 therapeutic users reported using acetaminophen for dental pain. The adjusted odds ratio for accidental overdose due to dental pain compared with other reasons for use was 12.8 (95% confidence interval, 4.2-47.6). We found that patients with dental pain are at increased risk to accidentally overdose on acetaminophen compared with patients taking acetaminophen for other reasons. Emergency physicians should carefully question patients with dental pain about overuse of analgesics. Copyright © 2011 Elsevier Inc. All rights reserved.

    Full text: Purpose: During a control of the safety measures at the Radiology Service in a local hospital in Buenos Aires, a lack of an appropriate shielding in the X-ray equipment was detected. Methods and Materials: Therefore studies were performed in the group of physicians and technicians exposed and in an age and sex matched group of non-exposed physicians and technicians. Check-ups included thyroid sonography, circulating thyroid hormones, TSH and thyroid antibodies. The exposed group included 9 females and 5 males, while the non-exposed group comprised 8 females and 5 males. Results: No thyroid abnormalities were found in the non-exposed patients. On the contrary in the exposed cohort in 11 out of 14 patients nodular goiter was diagnosed, while an additional patient presented diffuse goiter. In 5 out of the 12 patients with goiter, nodule growth or the appearance of new nodules was observed along the follow-up. Four patients presented changes in thyroid function: two had elevated basal TSH with increased titters of anti TPO antibodies in one, while another showed an abnormal TRH-TSH test. A fourth patient had low total T 4 values. Other abnormalities included: sperm abnormalities in 2 out of the 5 males, dry-eye syndrome in other two, mammary nodules in one female and a basocellular epithelioma in another one. Conclusions: accidental irradiation leads to thyroid abnormalities, such as the appearance of nodules and alterations in thyroid function. (author)

  8. Accidental over-exposure from dental X-ray equipment

    Energy Technology Data Exchange (ETDEWEB)

    Phillips, B G [National Radiological Protection Board, Harwell (UK)

    1976-07-01

    A description is given of an unusual dental X-ray procedure which resulted in accidental over-exposure both to the dentist and to several of his patients when a short-circuit was present in newly-installed equipment. The short-circuit by-passed the exposure control and energized the tube for certain orientations of the X-ray tube. The dentist left the patients, who wore protective aprons, to initiate the exposure themselves, using the control button. Although the warning lights were on, the dentist was not present in the room during the exposure, and the over-exposures were only detected when the developed X-ray films were found to be completely blackened. A reconstruction of the procedure enabled estimates to be made of the dose equivalents to the dentist's body and to the skin of the head, the eyes and the gonads of the patients. The dentist had overlooked several of basic principles recommended in the Code of Practice for the Protection of Persons against Ionizing Radiations from Medical and Dental Use (1972). It is pointed out that incidents involving failure of dental equipment (usually the timer mechanism) are not infrequent.

  9. Effectiveness of cleanup criteria relative to an accidental nuclear release

    International Nuclear Information System (INIS)

    Chen, S.Y.; Yuan, Y.C.

    1988-01-01

    In the event of an accidental nuclear release, the associated long-term radiological risks would result primarily from ground contamination pathways. Cleanup of the contaminated ground surfaces is a necessary step toward reducing the radiological risk to the general population. Ideally, the radiological risk decreases as the level of cleanup effort increases; however, as the cleanup criterion (i.e., the required contaminant concentration after cleanup) becomes more stringent, the cleanup effort may become prohibitively costly. This study examines several factors that are important in determining the effectiveness of the cleanup criteria for selected radionuclides: (a) annual individual dose commitment (mrem/yr), (b) total population environmental dose commitment (person-rem), and (c) total area (km 2 ) requiring cleanup following an accident. To effectively protect the general population, the benefits of cleanup should be weighed against the potentially large increase in cleanup area (and the associated costs) as the cleanup criterion becomes more stringent. The effectiveness of cleanup will vary, depending largely on site-specific parameters such as population density and agricultural productivity as well as on the amount and type of radionuclide released. Determination of an optimum cleanup criterion should account for all factors, including a comprehensive cost/benefit analysis

    1998-01-01

    In case of accidental marine pollution, Cedre and Meteo-France, within the framework of their own public service missions, provide assistance to the French authorities in charge of pollution response. Meteo-France has developed a numerical marine oil pollution transport model, named MOTHY, designed to simulate the transport of oil in three dimensions. A hydrodynamic ocean model is linked to an oil spill model including current shear, vertical movements and fate of the oil. The use of a global atmospheric model for atmospheric forcing enables world-wide application of the model. This oil spill response system has been operational since February 1994. In case of marine pollution, Meteo-France send meteorological forecasts and oil spill drift forecasts to Cedre. In return, by its experimentations and interventions on actual pollution, Cedre is contributing to the improvement and validation of the model. New developments, exercises and training are conducted jointly. This paper summarizes the key features of MOTHY and presents some examples of model applications. (author)

Laparoscopic cystectomy. Accidental retention of a portion of the capsule and adjacent ovarian tissue of the endometrioma in SC cellular tissue. Months after surgery, a SC tumor was formed under the surgical incision. It was subsequently excised. Observation of tumor growth during menstrual cycles and ovulation induction; anatomopathologic study of the tissue after its extirpation. The tumor grew spontaneously in the periovulatory period and during treatments of ovulation induction. The anatomopathologic report of the tumor, removed 15 months after the first surgery, revealed functioning ovarian tissue with vessels of neoformation. This is the first description of autografted ovarian tissue in humans. We describe that the ovary can maintain its ovulatory function even in the absence of its pedicel. Also, we suggest that extirpation of surgical material through the incision of the trocar is not recommended, as the possibility of "sowing" or of autografts may occur.

    RECUPERARE method has been developed for operating feedback analysis and built on the French Human Reliability Analysis (HRA) principles. It is used to study the causes of human errors or technical failures occurred in French PWRs and the recovery process of events. Based on an event classification (6 categories) model according to the nature of the link between failure and recovery, the identified and recorded data are: the causes of the defects (technical, human, organizational) and the context in which they appear; the factors of the recovery performance (depending on technical and organizational aspects); a chronological analysis, designed to collect delays between failures and their detection/recovery for each event. About 3600 events reported in French PWRs (1997-2003) had been reviewed through this model. Initially, the weight of factors and the most important factors, which influenced the detection and recovery delay, are defined. For this purpose, the regression Partial Least Square (PLS) is used. Then, to link RECUPERARE results with pre-accidental data, conditional probabilities of events linked between them by a cause and effect relationship are calculated. For this, the Bayesian method with the Bayesian network is built with the PLS obtained results and applied. This constitutes a first approach to take into account in HRA the human and organizational factors highlighted by operating feedback. (author)

  13. Taking in account of contextual parameters in post accidental radioecology

    International Nuclear Information System (INIS)

    Renaud, Ph.; Maubert, H.; Bernie, J.C.

    1997-01-01

    The consequences on agricultural or breeding products of a radioactive accidental release are strongly linked to the context in which radioactive deposits occur: for example conditions of deposition in relation with agricultural and feeding schedules. These contextual parameters lead to a variation of results given by models greater than transfer factors uncertainties. For example, cow milk contamination stretches on several decades during the months following deposit as a function of feeding practices. In the same way, if a wheat plant receives the deposit during grain development, harvested grains will have a contamination level 10 3 to 10 4 times higher that if deposition occurs before the growing stage. To create a decision support system like the ASTRAL software, the need to realize a modelling of these contextual parameters has been encountered. Moreover, to help experts for evaluations, default informations relative to agricultural and breeding practices for France are given through databases. However, in case of a real accident, it would be important to re-initialize these contextual parameters which change from year to year, in order to obtain more precise assessments. (authors)

    A meso-scale wind field forecast model was designed for emergency environmental assessment in case of accidental release of radiative materials from a nuclear power station. Actual practice of the model showed that it runs fast, has wind field prediction function, and the result given is accurate. With meteorological data collected from weather stations, and pre-treated by a wind field diagnostic model, the initial wind fields at different times were inputted as initial values and assimilation fields for the forecasting model. The model, in turn, worked out to forecast meso-scale wind field of 24 hours in a horizontal domain of 205 km x 205 km. And then, the diagnostic model was employed again with the forecasting data to obtain more detail information of disturbed wind field by local terrain in a smaller domain of 20.5 km x 20.5 km, of which the nuclear power station is at the center. Using observation data in January, April, July and October of 1996 over the area of Hangzhou Bay, wind fields in these 4 months were simulated by different assimilation time and number of the weather stations for a sensitive test. Results indicated that the method used here has increased accuracy of the forecasted wind fields. And incorporating diagnostic method with the wind field forecast model has greatly increased efficiency of the wind field forecast for the smaller domain. This model and scheme have been used in Environmental Consequence Assessment System of Nuclear Accident in Qinshan Area

    Vulvovaginitis is the most frequent gynecologic pathology among prepubertal females. An infectious cause is found in 30% of cases and is highly associated with the presence of vaginal discharge upon examination. Neisseria gonorrhoeae may be one of the causative agents. Since N. gonorrhoeae is a common sexually transmitted disease, sexual abuse should be considered in the pediatric setting. We report the case of a 5-year-old girl with N. gonorrhoeae vulvovaginitis. Her previous history, multiple interviews with the patient and her parents, and clinical examination showed no evidence or signs of sexual abuse. Both parents presented gonorrhea, urethritis for the father and vaginitis for the mother. The discrepancy between pediatric evaluation and the presence of a bacterium associated with sexually transmitted disease led us to consider other means of contamination. Previous studies have shown that other routes of transmission are possible but are often neglected. Hence, contamination can be transmitted by the hands or mostly through passive means (towels, rectal thermometer, etc.). Many epidemics have been noted in group settings with young girls with no evidence of sexual transmission. Therefore, we concluded that this patient's infection was likely an accidental transmission within her family. The acknowledgement of these transmission routes is very important in order to avoid misguided suspicion of sexual abuse and the possible traumatic family and psychosocial consequences.

    2011-04-15

    The physicochemical qualities of an accidental discharge of refinery liquid waste, water, and soil sediment of that effluent-receiving water body (canal) were investigated. Analyses of the discharge, qualities of water, and sediment of the canal showed high parametric concentrations. Investigations revealed that the discharge took place form the spent caustic that was generated from the caustic wash tower of Fluidized Catalytic Cracker of the refinery. A simple but realistic model was suggested for the remediation of sediments of the canal with an estimated cost of about US $1.86 million. Recommendations were made to prevent such discharges and to revise thoroughly the Indian effluent discharge standards in force for petroleum oil refinery. Subsequently, revised standards were notified under Indian guidelines. Interestingly, cyanide besides many other parameters was introduced into these standards. Furthermore, Volatile Organic Compound (VOC) was also stipulated as an emission parameter from the waste water treatment plants. Concentration- and mass-based standards thus promulgated were stricter than the existing standards. (orig.)

    RECUPERARE method has been developed for operating feedback analysis and built on the French Human Reliability Analysis (HRA) principles. It is used to study the causes of human errors or technical failures occurred in French PWRs and the recovery process of events. Based on an event classification (6 categories) model according to the nature of the link between failure and recovery, the identified and recorded data are: the causes of the defects (technical, human, organizational) and the context in which they appear; the factors of the recovery performance (depending on technical and organizational aspects); a chronological analysis, designed to collect delays between failures and their detection/recovery for each event. About 3600 events reported in French PWRs (1997-2003) had been reviewed through this model. Initially, the weight of factors and the most important factors, which influenced the detection and recovery delay, are defined. For this purpose, the regression Partial Least Square (PLS) is used. Then, to link RECUPERARE results with pre-accidental data, conditional probabilities of events linked between them by a cause and effect relationship are calculated. For this, the Bayesian method with the Bayesian network is built with the PLS obtained results and applied. This constitutes a first approach to take into account in HRA the human and organizational factors highlighted by operating feedback. (author)

    Full Text Available We report a case of accidental cutaneous burns caused by salbutamol metered dose inhaler. A 9-year-old boy underwent dental extraction at a children's hospital and was incidentally noted to have burn injuries on dorsum of both hands. On questioning, the boy revealed that a few days ago his 14-year-old brother, who is an asthmatic, playfully sprayed his salbutamol metered dose inhaler on the back of both his hands with the inhaler's mouth piece being in direct contact with the patient's skin. On examination, there was a rectangular area of erythema with superficial peeling on the dorsum of both hands, the dimensions of which exactly matched those of the inhaler's mouthpiece. It is possible that the injury could have been a chemical burn from the pharmaceutical/preservative/propellant aerosol or due to the physical effect of severe cooling of the skin or mechanical abrasive effect of the aerosol blasts or a combination of some or all the above mechanisms. This case highlights the importance of informing children and parents of the potentially hazardous consequences of misusing a metered dose inhaler.

    Full Text Available Background. 4-Aminopyridine (4-AP is a drug that is used to improve motor fatigue in patients suffering from multiple sclerosis (MS. Medication error can occur, as commercial preparation may not be available in some countries. Case Presentation. A 58-year-old woman with progressive MS presented with status epilepticus. She was receiving 4-AP for more than 3 years. The symptoms started soon after the ingestion of a single pill that was supposed to contain 10 mg 4-AP, but further investigations revealed that each pill had been inadvertently prepared with an 100 mg 4-AP concentration. The patient was admitted to the intensive care unit (ICU for appropriate management (orotracheal intubation, sedation, and antiepileptic drugs. The first electroencephalogram (EEG showed abundant irregular spike-waves on the left central regions. Neurological condition gradually improved from day 7, while the EEG did not reveal any more electrical seizures but was still consistent with toxic encephalopathy. The patient stayed in the ICU until day 13. At discharge from the rehabilitation ward (2.5 months later, the patient had not yet recovered her previous cognitive and functional condition. Conclusion. A single 100 mg 4-AP accidental overdose may cause serious immediate complications, with a slow and incomplete neurological recovery.

    Highlights: • Conservative early dose of different unit fusion radioactivity release were assessed. • Data of accident level in INES for fusion reactor were proposed. • Method of environmental restoration time after fusion accident was proposed. • The maximum possible accident level for ITER like fusion reactor is 6. • We need 34–52 years to live after the fusion hypothetical accident. - Abstract: As an important index shaping the design of fusion safety system, evaluation of public radiation consequences have risen as a hot topic on the way to develop fusion energy. In this work, the comprehensive public early dose was evaluated due to unit gram tritium (HT/HTO), activated dust, activated corrosion products (ACPs) and activated gases accidental release from ITER like fusion reactor. Meanwhile, considering that we cannot completely eliminate the occurrence likelihood of multi-failure of vacuum vessel and tokamak building, we conservatively evaluated the public radiation consequences and environment restoration after the worst hypothetical accident preliminarily. The comparison results show early dose of different unit radioactivity release under different conditions. After further performing the radiation consequences, we find it possible that the hypothetical accident for ITER like fusion reactor would result in a level 6 accident according to INES, not appear level 7 like Chernobyl or Fukushima accidents. And from the point of environment restoration, we need at least 69 years for case 1 (1 kg HTO and 1000 kg dust release) and 34–52 years for case 2 (1 kg HTO and 10kg–100 kg dust release) to wait the contaminated zone drop below the general public safety limit (1mSv per year) before it is suitable for human habitation.

    Biosafety of nanomaterials has attracted much attention recently. We report here a case where accidental human eye exposure to biogenic nanosized calcium phosphate in the form of calcifying nanoparticles (CNP) raised a strong IgG immune response against proteins carried by CNP. The antibody titer has persisted over ten years at the high level. The IgG was detected by ELISA using CNPs propagated in media containing bovine and human serum as antigen. The exposure incident occurred to a woman scientist (WS) at a research laboratory in Finland at 1993. CNP, also termed "nanobacteria", is a unique self-replicating agent that has not been fully characterized and no data on biohazards were available at that time. Before the accident, her serum samples were negative for both CNP antigen and anti-CNP antibody using specific ELISA tests (Nanobac Oy, Kuopio, Finland). The accident occurred while WS was harvesting CNP cultures. Due to a high pressure in pipetting, CNP pellet splashed into her right eye. Both eyes were immediately washed with water and saline. The following days there was irritation and redness in the right eye. These symptoms disappeared within two weeks without any treatment. Three months after the accident, blood and urine samples of WS were tested for CNP cultures (2), CNP-specific ELISA tests, and blood cell counts. Blood cell counts were normal, CNP antigen and culture tests were negative. A high IgG anti-CNP antibody titer was detected (see Figure). The antibodies of this person have been used thereafter as positive control and standard in ELISA manufacturing (Nano-Sero IgG ELISA, Nanobac Oy, Kuopio, Finland).

  10. Nuclear power: Accidental releases - practical guidance for public health action

    International Nuclear Information System (INIS)

    1987-01-01

    The disaster at Chernobyl, USSR, has caused a major crisis of confidence in nuclear safety, and highlighted the need for comprehensive contingency planning for - and emergency response to - such accidents. This report gives practical guidance on how the authorities should deal with an accident in any type of nuclear installation, whether it involves accidental releases to the air or into water. It is based on principles developed in a previous WHO report published in 1984. It summarizes the range of accidents for which plans need to be made to protect the public, the measures to be taken and the levels of dose at which they should be applied. It indicates how to measure the levels of exposure and what are the most likely routes of exposure. It then outlines the problems faced by public health authorities and medical practitioners, and the administrative arrangements that will have to be made. The example used is of a standard pressurized light water reactor of the type currently used for electricity generation, but many of the features will be common to other nuclear installations as well. This report is addressed to those organizations and individuals responsible for public health in the event of a nuclear accident. It will also be of use to those medical practitioners who are not administratively responsible in an accident, but who may need to be aware of the consequences and of the action to be taken in the aftermath of an accident. Coordination is vital between the public health administration and the organizations with direct responsibilities in the event of an accident, and this report is essential reading for them all. 29 refs, 2 figs, 7 tabs

    Objectives The aims of this study were to (i) investigate the association between night work or long work weeks and the risk of accidental injuries and (ii) test if the association is affected by age, sex or socioeconomic status. Methods The study population was drawn from the Danish version of the European Labour Force Survey from 1999-2013. The current study was based on 150 438 participants (53% men and 47% women). Data on accidental injuries were obtained at individual level from national health registers. We included all 20-59-year-old employees working ≥32 hours a week at the time of the interview. We used Poisson regression to estimate the relative rates (RR) of accidental injuries as a function of night work or long work weeks (>40 hours per week) adjusted for year of interview, sex, age, socioeconomic status (SES), industry, and weekly working hours or night work. Age, sex and SES were included as two-way interactions. Results We observed 23 495 cases of accidental injuries based on 273 700 person years at risk. Exposure to night work was statistically significantly associated with accidental injuries (RR 1.11, 99% CI 1.06-1.17) compared to participants with no recent night work. No associations were found between long work weeks (>40 hours) and accidental injuries. Conclusion We found a modest increased risk of accidental injuries when reporting night work. No associations between long work weeks and risk of accidental injuries were observed. Age, sex and SES showed no trends when included as two-way interactions.

    2018-01-01

    The paper is devoted to the assessment of accidental risks occurring at the works engaged in stone extracting and petroleum production. Two basic kinds of accidents common for stone extracting and petroleum production have been chosen to be discussed in the part under consideration. The most dangerous accidental situation characteristic for a stone milling line is an unsanctioned explosion, UE, of blasting agents used for the development of stone deposits. The analysis of a risk occurrence in certain accidental situations is to be carried out. With reference to petroleum extraction, a combustibles and lubricants (C & L) explosion is the most dangerous of characteristic accidental situations. To reveal the most probable causes of accidental situations to be realized, a graph of cause and effect relations has been constructed for each of the accidental situations most probable causes to real situation of an accident. Disasters of a natural origin are the most probable causes of unsanctioned explosions at the deposits of stone raw materials. Technology related natural disasters are the most probable causes of unsanctioned explosions to be realized at multiple well platforms engaged in petroleum production.

    Accidental falls are a major public health concern among people of all ages. Little is known about whether an individual-level housing-based socioeconomic status measure is associated with the risk of accidental falls. Among 12,286 Mayo Clinic Biobank participants residing in Olmsted County, Minnesota, subjects who experienced accidental falls between the biobank enrollment and September 2014 were identified using ICD-9 codes evaluated at emergency departments. HOUSES (HOUsing-based Index of SocioEconomic Status), a socioeconomic status measure based on individual housing features, was also calculated. Cox regression models were utilized to assess the association of the HOUSES (in quartiles) with accidental fall risk. Seven hundred eleven (5.8%) participants had at least one emergency room visit due to an accidental fall during the study period. Subjects with higher HOUSES were less likely to experience falls in a dose-response manner (hazard ratio: 0.58; 95% confidence interval: 0.44-0.76 for comparing the highest to the lowest quartile). In addition, the HOUSES was positively associated with better health behaviors, social support, and functional status. The HOUSES is inversely associated with accidental fall risk requiring emergency care in a dose-response manner. The HOUSES may capture falls-related risk factors through housing features and socioeconomic status-related psychosocial factors. Copyright © 2017 Elsevier Inc. All rights reserved.

    1969-10-15

    A description is given of an accident involving extremely uneven irradiation (ranging from 50 rads to 1.7 Mrads), in which a worker carried a {sup 137}Cs source belonging to an industrial gamma radiography unit in his trouser pockets for a total period of 18 hours on 3 and 4 May 1968. Low irradiation of the haematopoietic and gastrointestinal organs inhibited the occurrence of the acute syndrome. The front of the thighs, the inguinoscrotal region, and to a lesser extent the hands, were the areas most affected by lesions. The radiation doses delivered to the affected areas were estimated from biological radiation dosimetry parameters (the extent and chronological order of some of the lesions) and from experimental data on the dose as a function of distance and depth of the tissues, obtained by reconstructing the accident with a phantom and a set of thermoluminescent dosimeters. The paper describes the appearance a few days later of wet radiation dermatitis covering areas which gradually grew until they reached approximately the limit represented by the 1000 rads isodose line. Progression of the radiation dermatitis was complete towards the end of May. At the beginning of June dry epidermal desquamation extending approximately as far as the 500 rads line was observed. With the passage of time there occurred muscular atrophy of both legs and extensive oedema of the inguinoscrotal area. The appearance of extensive femoral haemorrhages in November 1968 and January 1969 made it necessary to amputate first the lower left limb, and then the right. The rate of chromosomal aberrations in the peripheral blood confirms the low doses absorbed by the blood system (about 50 rads). A summary of results of the analyses made is given, together with comments on the prognosis of the patient's development, based on the distribution of the radiation dose received.

    Full Text Available We report the case of a 25-year-old woman, who received epidural analgesia for labor pain and subsequently presented post-dural puncture headache. Conservative treatment was applied and epidural blood patch was performed. In the absence of clinical improvement and due to changes in the postural component of the headache, a brain imaging test was performed showing a bilateral subdural hematoma.The post-dural puncture headache is relatively common, but the lack of response to established medical treatment as well as the change in its characteristics and the presence of neurological deficit, should raise the suspicion of a subdural hematoma, which although is rare, can be lethal if not diagnosed and treated at the right time. Resumo: Apresentamos o caso clínico de uma paciente de 25 anos de idade, na qual uma técnica peridural foi realizada durante o trabalho de parto e posteriormente apresentou cefaleia com características de cefaleia pós-punção dural. Foi iniciado tratamento conservador e tampão de sangue peridural. Devido a ausência de melhora clínica e à mudança do componente postural da cefaleia, decidiu-se realizar um exame de imagem cerebral que demostrou a presença de hematoma subdural bilateral.A cefaleia pós-punção dural é relativamente frequente, mas a falta de resposta ao tratamento médico instaurado, assim como a mudança em suas características e a presença de foco neurológico, devem levantar a suspeita de presença de um hematoma subdural que, embora infrequente, pode chegar a ser devastador se não for diagnosticado e tratado oportunamente.

    Details of serious injuries to children ≤16 yrs. of age that necessitated urgent surgical intervention by the Department of Pediatric Surgery of the University Hospital of Lausanne, Switzerland were recorded into a database registry. Some 15 110 entries listed the precise time of injury, and 3114 (20.6%) of these resulted from participating in sport-associated activities. Time-of-day, day-of-week and month-of-year differences in the total number of children's accidental sport injuries (CASI) were validated. Time-of-day patterns were substantiated for "All Sports", for both boys and girls 5-16 yrs. of age, with more boys than girls experiencing incidents at almost every clock hour. Moreover, they were substantiated for this age group for each of the six different considered individual and team CASI categories - Physical Exercises at School; Bicycle Riding; Roller Skating and Skateboarding; Snow Skiing, Sledding, and Tobogganing; Soccer; and Basketball - for which sample sizes were sufficiently large (n > 230) to perform statistical assessment by ANOVA, t-test and/or cosinor analyses. CASI happened primarily between 06:00 and 17:00 h and rarely evening or overnight. Features - specific clock-time and number of peaks and troughs - of the CASI daily curve pattern of the individual six sport categories differed somewhat; nonetheless, excess or greatest number of CASI typically happened between 12:00 and 14:00 h, even when summertime and other scheduled school and family vacation periods were taken into account. Time-of-day and day-of-week patterns in the boy/girl sex ratio were also validated, with midday and Friday/Saturday peaks, respectively. We hypothesize the prominent 24 h patterns of CASI of 5-16 yr. olds, in particular, are representative of a combination of several determinants. These include exogenous periodic and cyclic environmental and sociocultural phenomena, genetic sex-related traits, plus endogenous circadian cognitive and physiologic rhythms

  4. Results of dose calculations for NET accidental and normal operation releases of tritium and activation products

    1992-08-01

    This report documents conditions, data and results of dose calculations for accidental and normal operation releases of tritium and activation products, performed within the NET subtask SEP2.2 ('NET-Benchmark') of the European Fusion Technology Programme. For accidental releases, the computer codes UFOTRI and COSYMA for assessing the radiological consequences, have been applied for both deterministic and probabilistic calculations. The influence on dose estimates of different release times (2 minutes / 1 hour), two release heights (10 m / 150 m), two chemical forms of tritium (HT/HTO), and two different model approaches for the deposition velocity of HTO on soil was investigated. The dose calculations for normal operation effluents were performed using the tritium model of the German regulatory guidelines, parts of the advanced dose assessment model NORMTRI still under development, and the statistical atmospheric dispersion model ISOLA. Accidental and normal operation source terms were defined as follows: 10g (3.7 10 15 Bq) for accidental tritium releases, 10 Ci/day (3.7 10 11 Bq/day) for tritium releases during normal operation and unit releases of 10 9 Bq for accidental releases of activation products and fission products.

    Full Text Available The purpose of this study was to examine county and state-level accidental poisoning mortality trends in Pennsylvania from 1979 to 2014.Crude and age-adjusted death rates were formed for age group, race, sex, and county for accidental poisonings (ICD 10 codes X40-X49 from 1979 to 2014 for ages 15+ using the Mortality and Population Data System housed at the University of Pittsburgh. Rate ratios were calculated comparing rates from 1979 to 2014, overall and by sex, age group, and race. Joinpoint regression was used to detect statistically significant changes in trends of age-adjusted mortality rates.Rate ratios for accidental poisoning mortality in Pennsylvania increased more than 14-fold from 1979 to 2014. The largest rate ratios were among 35-44 year olds, females, and White adults. The highest accidental poisoning mortality rates were found in the counties of Southwestern Pennsylvania, those surrounding Philadelphia, and those in Northeast Pennsylvania near Scranton.The patterns and locations of accidental poisoning mortality by race, sex, and age group provide direction for interventions and policy makers. In particular, this study found the highest rate ratios in PA among females, whites, and the age group 35-44.

    Background. Child abuse specialists rely heavily on diagnostic neuroimaging. Objectives. Study objectives were: (1) to compare the frequencies of six specific intracranial CT abnormalities in accidental and non-accidental pediatric head trauma, and (2) to assess interobserver agreement regarding these CT findings. Materials and methods. Three pediatric radiologists blindly and independently reviewed cranial CT scans of pediatric patients who sustained closed head trauma between 1991 and 1994. All patients were less than 4 years of age. Study cases included thirty-nine (50 %) with non-accidental head trauma and thirty-nine (50 %) with accidental head trauma. Each scan was evaluated for the presence or absence of the following six intracranial findings: (1) interhemispheric falx hemorrhage, (2) subdural hemorrhage, (3) large (non-acute) extra-axial fluid, (4) basal ganglia edema, (5) posterior fossa hemorrhage, and (6) frontal-parietal shearing tear(s). Interobserver agreement was calculated as the percentage of total cases in which all reviewers agreed a specific CT finding was present or absent. Diagnosis required independent agreement by all three pediatric radiologists. The frequencies of these six intracranial CT abnormalities were compared between the two study groups by Chi-square analysis and Fisher's exact test. Results. Interobserver agreement between radiologists was greater than 80 % for all lesions evaluated, with the exception of frontal-parietal shearing tear(s). Interhemispheric falx hemorrhage, subdural hemorrhage, large (non-acute) extra-axial fluid, and basal ganglia edema were discovered significantly more frequently in non-accidental trauma (P ≤.05). Conclusion. Although not specific for child abuse, discovery of these intracranial CT abnormalities in young patients should prompt careful evaluation of family and injury circumstances for indicators of non-accidental trauma.

    The fundamental mechanism of the bound states in the continuum is the full destructive interference of two resonances when two eigenlevels of the closed system are crossing. There is, however, a wide class of quantum chaotic systems which display only avoided crossings of eigenlevels. As an example of such a system we consider the Sinai billiard coupled with two semi-infinite waveguides. We show that notwithstanding the absence of degeneracy bound states in the continuum occur due to accidental decoupling of the eigenstates of the billiard from the waveguides. - Highlights: • Bound states in the continuum in open chaotic billiards occur to accidental vanishing of coupling of eigenstate of billiard with waveguides.

    Accidents are a preventable cause of death. Unfortunately it accounts for a large number of deaths in many societies. In Kuwait, road traffic accidents (RTA) is the leading cause of death in young people. The study investigated the patterns of accidental deaths in Kuwait, one of the Gulf States which incorporates a wide variety of multi-ethnic communities. The study was retrospective from 2003-2009. Data of forensic cases were collected from the general department of criminal evidence (GDCE) in the ministry of interior (MOI).We attempted to find out causes of accidental death and the prevelance of each cause. Furthermore, the relationship of demographic factors (eg. Age, sex, marital status and nationality) with each cause of accidental death in Kuwait were studied. The material of this study constituted a total of 4886 reported accidental deaths referred for Medico-legal examination. Road traffic accidents was by far the most prevalent cause of death (64.6%) followed by fall from height (13.1%). Poisoning and mine explosions were amongst the least common causes. The government of Kuwait needs to take strong measures to promote safety in the workplace and households by educational campaigns.

    During the last few years the radiopathology service of the Curie Foundation has admitted more than a hundred patients who were followed and treated for irradiation or suspected irradiation after a work accident. Accidents followed by clinical symptoms account for about half the cases examined. Some of these clinical signs were benign whereas others developed very seriously, all possible conditions between these two extremes being represented. This report neglects cases of high total exposure and deals only with those of partial irradiation where local symptoms predominate, usually at the distal extremities of the upper limbs and exceptionally at the root or distal extremity of the lower limbs. Six clinical cases were selected as particularly revealing and are discussed below: accidental exposure of both hands to an iridium-192 source; chronic exposure to X-rays (left hand and right lower half-lip); accidental exposure of the right hand and antero-external face of the right thigh to a iridium-192 source; acute accidental exposure of the left hand to X-rays emitted under 50 kV; accidental exposure of both hands to cobalt-60 radiation; radiolesions of the left lower limb following a critical power excursion (gamma rays and neutrons) [fr

    To investigate the impact of narrative verdicts on suicide statistics among 10-19-year-olds; to identify the number and rate of suicide and accidental deaths, particularly in 10-14-year-olds. National cohort study. England and Wales. Mid-year population estimates from the Office for National Statistics (ONS) were used to calculate rates per 100,000 population for suicide (undetermined and suicide verdicts) and accidental deaths (poisoning, hanging) for those aged 10-14 and 15-19. Trends in rates over time (2001-2010) were investigated using Poisson regression. Interaction tests were carried out to determine differences in trends between the two time periods (2001-2005 and 2006-2010). There were 1523 suicides (2.25/100,000). Suicide rates were highest in those aged 15-19 years (4.04/100,000) and in males (3.14/100,000). Between 2001 and 2010, rates significantly decreased among those aged 15-19 years (incidence rate-ratio (IRR): 0.95; 95% CI 0.93 to 0.97), with no change in rates of accidental deaths (IRR: 1.01, 95% CI 0.95 to 1.07). However, there was a significant interaction between the two time periods for accidental poisonings (2001-2005: IRR: 0.79 (95% CI 0.69 to 0.91); 2006-2010: IRR: 1.01 (95% CI 0.89 to 1.15), interaction p=0.012) and accidental hangings (2001-2005: IRR: 0.93 (95% CI 0.76 to 1.14); 2006-2010: IRR: 1.25 (95% CI 1.04 to 1.49), interaction=0.01) Undetermined deaths significantly decreased among females aged 15-19 yeras (IRR: 0.93; 95% CI 0.88 to 0.98). There were no significant trends among 10-14-year-olds. Rates of suicide are higher among older adolescents and males. There was a significant fall in suicide rates in males aged 15-19 years that was not accounted for by changes in rates of accidental death. The absence of a significant trend in suicide or accidental deaths in those aged 10-14 years may have been the result of small numbers. However, monitoring should continue to identify longitudinal trends in all young people.

    This study stemmed from the data gathered by a research conducted by the coordinator of the Department of Healthcare Services and a group of nurses involved in a research on accidental falls in hospitalized children at the "G. Gaslini" Children's Hospital and Scientific Research Institute in Genoa, Italy. The first retrospective study evaluated the accidental falls in hospitalized children referred to the three-year period 2003-2006, while the second perspective study, referred to the trimester March-May 2007, found that the main cause of falls in children was parent's distraction. The method adopted in the first phase of our study was a proactive risk analysis (The Basics of Healthcare Failure Mode and Effect Analysis), identified in the first place by the VA National Centre for Patient Safety and applied to the "Child and parent hospital admission process". This proactive risk analysis has proven to be very effective in preventing the risk of accidental falls in hospitalized children through effective communication and educational interventions. The second phase of our study consisted of two Focus Groups for accidental traumatic events. The analysis of the results of the study showed how effective communication is instrumental, not only to have a better awareness of the children and their parents during their stay in hospital, but also to implement educational sessions on prevention to reduce the risk of accidental traumatic events. The present study contributes to improve safety and the quality of care by motivating nurses to keep their attention high on falls in hospitalized children, by monitoring and the development of new risk assessment tools.

MÉTODOS: Estudo caso-controle de base populacional sobre mortes fetais e neonatais precoces realizado na região sul do Município de São Paulo. Foram coletados dados em entrevistas domiciliares e de prontuários hospitalares. Os motivos referidos pelas mães para a ocorrência de partos domiciliares foram obtidos nas entrevistas. Os fatores de risco para o parto domiciliar foram obtidos comparando-se com os partos hospitalares. Os dados foram analisados separadamente para perdas fetais, óbitos neonatais e sobreviventes. Foram utilizadas odds ratio, intervalo de confiança de 95% e o teste exato de Fisher para avaliar os fatores de risco e estimar o risco de morte. RESULTADOS: A freqüência de partos domiciliares de 0,2% no Sistema de Informações de Nascidos Vivos está sub-notificada. Quando ajustada, passa a ser de 0,4%, compatível com a encontrada em algumas cidades da Europa. Todos os partos domiciliares identificados foram acidentais. O parto domiciliar acidental está associado ao aumento da mortalidade fetal e neonatal precoce. Características sociais das mães e da gestação estão associadas à ocorrência de partos domiciliares acidentais, e não são sempre as mesmas para os três tipos de desfecho (óbito fetal, óbito neo-natal precoce e sobreviventes. A falta de transporte para o hospital foi indicada como motivo para os partos domiciliares por 30% das mães. Falhas do sistema de saúde em reconhecer a iminência do parto e a não disponibilidade de atendimento de urgência contribuíram para a ocorrência de alguns partos domiciliares. CONCLUSÕES: Apesar de serem eventos raros, pelo menos em área urbana, os partos domiciliares acidentais devem merecer atenção específica, já que acarretam aumento do risco de morte e parecem ser evitáveis.OBJECTIVE: To identify the frequency, risks

    Una de las situaciones más limitantes en el análisis de integridad del combustible gastado durante el transporte, es el de los hipotéticos accidentes de caída del contenedor. El escenario que debe ser analizado en este tipo de accidentes, según especifica el título 10 de las Code Federal Regulations (10 CFR 71.73) de la NRC, es el de la caída libre del sistema combustible-contenedor desde una altura de nueve metros con el posterior impacto contra una superficie plana, rígida y horizontal en la posición más desfavorable. En concreto, en este artículo se realiza el análisis de la respuesta del combustible bajo el supuesto de caída en posición vertical del contenedor. Para este tipo de análisis, Enusa ha desarrollado y presenta en este artículo un modelo elasto-plástico de elementos finitos capaz de simular mediante un cálculo cuasiestático el comportamiento de una barra combustible irradiada durante el accidente postulado y evaluar su integridad estructural. Aproximaciones mediante un cálculo dinámico a este análisis también has sido acometidas y sus resultados podrán ser presentados en futuros artículos.

    2017-12-01

    A unique case of accidental hanging due to compression of the neck of an adult by the branches of a coffee tree is reported. The decedent was a 42-year-old male who was found dead in a semi prone position on a slope. His neck was lodged in a wedge formed by two branches of a coffee tree, with his legs angled downwards on the slope. Autopsy revealed two friction abrasions located horizontally on either side of the front of the neck, just above the larynx. The findings were compatible with compression of the neck by the branches of the tree, with the body weight of the decedent contributing to compression. Subsequent complete autopsy examination confirmed the cause of death as hanging. Following an inquest the death was ruled to be accidental.

    Full Text Available The helideck structure must satisfy the safety requirements associated with various environmental and accidental loads. Especially, there have been a number of fire accidents offshore due to helicopter collision (take-off and/or landing in recent decades. To prevent further accidents, a substantial amount of effort has been directed toward the management of fire in the safety design of offshore helidecks. The aims of this study are to introduce and apply a procedure for quantitative risk assessment and management of fires by defining the fire loads with an applied example. The frequency of helicopter accidents are considered, and design accidental levels are applied. The proposed procedures for determining design fire loads can be efficiently applied in offshore helideck development projects.

    The acute radiation syndrome has been characterized in different ways that involve risk for life and health of the people overexposed to ionizing radiations. This work intends to test a therapeutical total body irradiation (TBI) model as conditioning to bone marrow transplantation. With the purpose of evaluating the applicability of several biological indicators in accidental overexposures, a study was carried out in 46 patients undergoing TBI receiving doses between 10 Gy and 12 Gy. The following parameters were assessed: lipo peroxyde plasmatic levels (TBARS) and total plasma antioxidant activity, reticulocyte maturity index (RMI) and charges in lymphocyte subpopulations. These data suggest that TBARS could provide an useful evolutive indicator in accidental overexposed patients and RMI is an early indicator of bone marrow recovery after radioinduced aplasia

    2009-01-01

    Uranium Hexafluoride is a material used in the various processes which comprise the front end of the nuclear fuel cycle (conversion, enrichment and fuel fabrication). Confinement of UF 6 is a very important safety requirement since this material is highly reactive and presents safety hazards to humans. The present paper discusses the safety relevant aspects of accidental releases of UF 6 inside process confinement buildings. Postulated accidental scenarios are analyzed and their consequences evaluated. Implant releases rates are estimated using computer code predictions. A time dependent homogeneous compartment model is used to predict concentrations of UF 6 , hydrogen fluoride and uranyl fluoride inside a confinement building, as well as to evaluate source terms released to the atmosphere. These source terms can be used as input to atmospheric dispersion models to evaluate consequences to the environment. The results can also be used to define adequate protective measures for emergency situations. (author)

    2018-01-01

    Accidental cut-throat injuries are extremely rare and usually involve a sharp-edged weapon. In this paper, two cases of a cut-throat wound to two auto-rickshaw drivers are presented where the broken windshield of the auto-rickshaws was responsible for the wounds. In both the cases, fatal incised wounds were present over the neck, cutting the soft tissue along with the major vessels. The death occurred due to exsanguination caused by neck-vessel injury in one case and trachea along with neck-vessel injury in the second case. Although the wounds on the neck initially suggested homicide, they were found to have occurred accidentally as a result of a road traffic accident involving a head-on collision of auto rickshaws. The injuries were inflicted by the shattered glass of the windshield.

We report accidental poisoning with V. album mistaken for Allium ursinum (wild garlic), a wild plant used in soups and salads in Central Europe. Four adults (24-45 years) accidentally ingested V. album mistaken for A. ursinum in self-prepared salads and soups. Within 15-30 min of ingestion they developed nausea, vomiting, and abdominal pain. At the same time dizziness, tingling, dimmed and jumping vision, transient blindness, and confusion appeared. On arrival at the ED, all patients had sinus bradycardia and hypotension. Following treatment the patients were discharged well 24-48 h after ingestion. In patients presenting with gastrointestinal, neurological, and cardiovascular symptoms a history of wild plant ingestion suggests possible poisoning with V. album mistaken for wild garlic.

    The author briefly describes some approaches developed within the EURANOS European research programme between 2004 and 2009 which aims at promoting the building up of a European network (NERIS) for the management of nuclear accidental and post-accident situations. Notably, he comments the experiment which took place in the Montbeliard district where two types of radiological events have been modelled and simulated: an accident in the Fessenheim nuclear power plant with two scenarios of release, and a transportation accident with a release of radioactive caesium 137. He also evokes the Norwegian experience and some other actions in Finland, Great-Britain, Spain and Slovakia where reflections on the management of accidental and post-accident situations or crisis exercises have been organized

    Full Text Available Acute toxicity is a frequent but avoidable cause of morbidity and mortality in children especially in developing countries, including India. Present study assesses their pattern with relation to different age groupings. This retrospective study was conducted among all hospitalised paediatric victims of acute accidental poisoning at the King George Medical University; Lucknow during 2010 -11. Their history, baseline characteristics, clinical course and outcome was studied. Most children were male of less than three years with 4% overall mortality. Kerosene oil was implicated in most cases. Childhood poisoning is commonest during 1-3 years with a male preponderance. Household poisons; especially kerosene oil was responsible for most cases which was consumed accidentally. Parents must be educated and warned to keep these toxic ingredients safely in suitable containers and out of reach of their beloved children. Keywords: Forensic Science, Paediatric, Acute Poisoning, Kerosene, Outcome.

    Accidental marine oil spill pollution can result in severe environmental, ecological, economic and other consequences. This paper discussed the model of Marine Oil Spill Risk Mapping (MOSRM), which was constructed as follows: (1) proposing a marine oil spill risk system based on the typical marine oil spill pollution accidents and prevailing risk theories; (2) identifying suitable indexes that are supported by quantitative sub-indexes; (3) constructing the risk measuring models according to the actual interactions between the factors in the risk system; and (4) assessing marine oil spill risk on coastal city scale with GIS to map the overall risk. The case study of accidental marine oil spill pollution in the coastal area of Dalian, China was used to demonstrate the effectiveness of the model. The coastal areas of Dalian were divided into three zones with risk degrees of high, medium, and low. And detailed countermeasures were proposed for specific risk zones.

    An application as an Excel spreadsheet of the simplified modelling approach of tritium transfer in the environment developed by Tamponnet (2002) is presented. Based on the use of growth models of biological systems (plants, animals, etc.), the two-pool model (organic tritium and tritiated water) that was developed estimates the concentration of tritium within the different compartments of the food chain and in fine the dose to man by ingestion in the case of a chronic or accidental release of tritium in a river or the atmosphere. Data and knowledge have been implemented on Excel using the object-oriented programming language VisualBasic (Microsoft Visual Basic 6.0). The structure of the conceptual model and the Excel sheet are first briefly exposed. A numerical application of the model under a scenario of an accidental release of tritium in the atmosphere is then presented. Simulation results and perspectives are discussed. (author)

  3. External hazards in the PRA of Olkiluoto 1 and 2 NPP units - Accidental oil spills

    2014-01-01

    Oil transports in Finnish territorial waters have increased significantly during the last 10 years. The Gulf of Finland is at this moment a very important route of oil being transported from Russia to the Western Europe. Although the number of accidental oil spills is decreasing in amount and in size, there is a growing concern of their effects to nuclear power plants (NPPs). The amounts of oil transported on the Gulf of Bothnia are much smaller than on the Gulf of Finland. However, accidental oil spills have occurred also there, the size and amount of which are smaller, though. Accidental oil spills are often a result of grounding of a ship or collision of two ships, and often occur during harsh weather conditions like storm or dense fog. However, also coastal oil depots may break, the oil of which may spread over wide distances on the sea. The modelling of initiating events resulting from accidental oil spills includes oil spill response actions performed by the regional rescue services, alarming of the oil spill by the emergency response centre to the NPP rescue services and spill response by the NPPs rescue services. It is unclear what the consequences are if drifted oil would enter the coolant water tunnels. The effect of different oil types to the operation of the safety-related service water systems and components are being assessed. In the ultimate case, an oil spill would clog the inlet channels thus failing the ultimate heat sink of the NPP units. The licensee is evaluating what is the optimal way to operate the NPP units in the case that an oil slick is threatening the plant to ensure reactor core cooling and RHR. The continued operation of, and especially the cooling of, at least one auxiliary feedwater pump is critical in the mitigation of the initiating event. Strategies, like reversing the water flow of the cooling water channels or closing of the cooling water channels, are being evaluated. (authors)

    In this research I examine social ordering processes in Kakuma refugee camp in Kenya. I view the camp as an accidental city, by which I challenge the image of the camp as a temporary and artificial waiting space or a protracted refugee crisis per se. The reference to the city is both metaphorically and physically relevant. First, the metaphorical dimension of the city places refugees and their negotiation of space into the realm of the normal and the possible, contrary to prevailing not...

    Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for "Weightlifting." Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as "accidental" if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4,111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p injuries (n = 2,565) showed that the oldest categories (19-22 and 23-30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to "dropping" and "pinching" in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p injuries are the result of accidents that are potentially preventable with increased supervision and stricter safety guidelines.

    Sodium hypochlorite (NaClO) has been widely used in clinical practice as one of the most efficient root canal irrigants. Its properties include broad-spectrum antimicrobial activity and ability to dissolve necrotic tissues. However, when used improperly, NaClO can cause a series of adverse reactions, such as mucosal inflammation, irritation, or injury. This paper presents a case of accidental injection of NaClO in inferior alveolar nerve block anesthesia.

    Umberto Marcello Bracale

    2014-01-01

    Full Text Available The purpose of this paper is to report a salvage maneuver for accidental coverage of both renal arteries during endovascular aneurysm repair (EVAR of an infrarenal abdominal aortic aneurysm (AAA. A 72-year-old female with a 6 cm infrarenal abdominal aortic aneurysm was treated by endovascular means with a standard bifurcated graft. Upon completing an angiogram, both renal arteries were found to be accidentally occluded. Through a left percutaneous brachial approach, the right renal artery was catheterized and a chimney stent was deployed; however this was not possible for the left renal artery. A retroperitoneal surgical approach was therefore carried out with a retrograde chimney stent implanted to restore blood flow. After three months, both renal arteries were patent and renal function was not different from the baseline. Both endovascular with percutaneous access via the brachial artery and open retroperitoneal approaches with retrograde catheterization are feasible rescue techniques to recanalize the accidentally occluded renal arteries during EVAR.

    Quantitative approaches are part of the understanding of contour integration and the Gestalt law of good continuation. The present study introduces a new quantitative approach based on the a contrario theory, which formalizes the non-accidentalness principle for good continuation. This model yields an ideal observer algorithm, able to detect non-accidental alignments in Gabor patterns. More precisely, this parameterless algorithm associates with each candidate percept a measure, the Number of False Alarms (NFA), quantifying its degree of masking. To evaluate the approach, we compared this ideal observer with the human attentive performance on three experiments of straight contours detection in arrays of Gabor patches. The experiments showed a strong correlation between the detectability of the target stimuli and their degree of non-accidentalness, as measured by our model. What is more, the algorithm's detection curves were very similar to the ones of human subjects. This fact seems to validate our proposed measurement method as a convenient way to predict the visibility of alignments. This framework could be generalized to other Gestalts.

    2010-01-01

    Interest is increasing in the development of new methodologies for accidental dose assessment, exploiting the luminescence and dosimetric properties of objects and materials which can be usually found directly on exposed subjects and/or in the contaminated area. In this work, several types of ceramics employed for dental prosthetics restoration, including both innovative materials used as sub-frames for the construction of the inner part of dental crowns (core), and conventional porcelains used for the fabrication of the external layer (veneer), were investigated with regard to their thermally and optically stimulated luminescence (TSL and OSL respectively) properties, in view of their potential application in accidental dosimetry. The sensitivity to ionizing radiation proved to strongly depend on the type and brand of ceramic, with minimum detectable dose ranging from few mGy up to several tens of mGy. A linear dose-response was observed for most of the samples. However, the luminescence signals were characterised by a significant fading, which has to be taken into account for a reliable accidental dose assessment after a radiation exposure event.

    XOQ DW code is currently used to assess the atmospheric dispersion for the routine releases of radioactive gaseous effluents at Yonggwang nuclear power plants. This code was developed based on XOQDOQ code and an additional code is required to assess the atmospheric dispersion for potential accidental releases. In order to assess the atmospheric dispersion for the accidental releases, XOQAR code has been developed by using PAVAN code that is based on Reg. Guide 1.145. The terrain data of XOQ DW code inputs and the relative concentrations (X/Q) of XOQ DW code outputs are used as the inputs of the XOQAR code through the interface with XOQ DW code. By using this code, the maximum values of X/Q at exclusion area and low population zone boundaries except for sea areas were assessed as 1.33 x 10 -4 and 7.66 x 10 -6 sec/m 3 , respectively. Through the development of this code, a code system is prepared for assessing the atmospheric dispersion for the accidental releases as well as the routine releases. This developed code can be used for other domestic nuclear power plants by modifying the terrain input data

    After a presentation of the process which resulted in the setting up of an investigation aimed at testing recommendations for post-accidental management, this report indicates the objectives of this investigation: to study the application of recommendations made by the CODIR-PA (Management Committee - Post-Accidental Management) to the operators of the milk sector, and to define an action plan to carry on and resume production. According to the adopted methodology, the study comprised two phases. The first one comprised an analysis of applications in the milk sector, the study of operational consequences on a zoning proposed by the CORDI-PA on the milk sector and on milk products, and the study of the acceptability and feasibility of considered options. The second phase addressed the elaboration of an action plan to carry on and resume the activity. While identifying and assessing the various risks, it identified critical issues for carrying on or resuming milk production in a contaminated territory, and defined an action plan to implement by anticipation or in the post-accidental situation

    The development of a conceptual design of an industrial scale transmutation facility (EFIT) of several 100 MW thermal power based on Accelerator Driven System (ADS) is addressed in the frame of the European EUROTRANS Integral Project. In normal operation, the core power of EFIT reactor is removed through steam generators by four secondary loops fed by water. A safety-related Decay Heat Removal (DHR) system provided with four independent inherently safe loops is installed in the primary vessel to remove the decay heat by natural convection circulation under accidental conditions which lead to the Loss of Heat Sink (LOHS). In order to confirm the adequacy of the adopted solution for decay heat removal in accidental conditions, some multi-D analyses have been carried out with the SIMMER-III code. The results of the SIMMER-III code have been then used to support the RELAP5 1-D representation of the natural circulation flow paths in the reactor vessel. Finally, the thermal-hydraulic RELAP5 code has been employed for the analysis of LOHS accidental scenarios. (author)

    Unintentional injuries are the leading cause of death in children around the world and are an under-recognized public health problem in the United States. The purpose of this study was to highlight the nature of the problem in South Dakota and outline interventions that have been successful in reducing childhood injuries in other states. This quantitative retrospective study examined mortality files in South Dakota for children birth to 19 years of age who died between January 1, 2000 to December 28, 2007. Although the number of deaths declined considerably from 2006 to 2007, South Dakota had the second-highest rate in the nation of childhood unintentional injury deaths from all causes between 2000-2005. The majority of deaths occurred in males and were associated with transportation-related deaths. Suffocation was the leading cause of death for newborns to age 1 year. Childhood accidental death in South Dakota is clearly a critical public health problem. Intervention efforts to reduce deaths from unintentional injuries amongst children should be targeted as the leading causes of accidental death for specific age groups and American Indian youth. Physicians, health educators and policymakers must play a role in prevention targeting the high-risk groups in addition to advocating for policy changes to protect childhood safety. More stringent child restraint laws, graduated driving laws, smoking cessation programs for parents, creation of safer sleep environments and further investigation of why a high proportion of American Indian children die accidentally in South Dakota are all warranted.

    2002-01-01

    The analysis of accidental sequences associated with the Containment is one of the most important tasks during the development of the Probabilistic Safety Assessment (PSA) of nuclear plants mainly because of its importance on the mitigation of consequences of severe postulated accident initiating events. This paper presents a first approach of the Containment analysis of the INAP identifying failures and events that can compromise its performance, and outlining accidental sequences and Containment end states. The initial plant damage states, which are the input for this study, are based on the event trees developed in the PSA level 1 for the INAP. It should be emphasized that since this PSA is still in a preliminary stage it is subjected to further completion. Consequently, the Containment analysis shall also be revised in order to incorporate, in an extension as complete as possible, all initial plant damage states, the corresponding event trees, and the related Containment end states. Finally, it can be concluded that the evaluation of the qualitative analysis presented herein allows a concise and broad knowledge of the qualitative analysis presented herein allows a concise and broad knowledge of the development of accidental sequences related to the Containment of the INAP.

    Among the main causes of death in our country are car accidents, drowning and accidental burns. Strangulation is a potentially fatal injury and an important cause of homicide and suicide among adults and adolescents. In children, its occurrence is usually accidental. However, in recent years, several cases of accidental strangulation in children around the world have been reported. A 2-year-old male patient was strangled in a car window. The patient was admitted to the pediatric intensive care unit with a Glasgow Coma Scale score of 8 and presented with progressive worsening of respiratory dysfunction and torpor. The patient also presented acute respiratory distress syndrome, acute pulmonary edema and shock. He was managed with protective mechanical ventilation, vasoactive drugs and antibiotic therapy. He was discharged from the intensive care unit without neurological or pulmonary sequelae. After 12 days of hospitalization, he was discharged from the hospital, and his state was very good. The incidence of automobile window strangulation is rare but of high morbidity and mortality due to the resulting choking mechanism. Fortunately, newer cars have devices that stop the automatic closing of the windows if resistance is encountered. However, considering the severity of complications strangulated patients experience, the intensive neuro-ventilatory and hemodynamic management of the pathologies involved is important to reduce morbidity and mortality, as is the need to implement new campaigns for the education of parents and caregivers of children, aiming to avoid easily preventable accidents and to optimize safety mechanisms in cars with electric windows.

A case of BiTine ring ingestion is presented with a note on inefficient ring separation forceps.Case description: A 28-year-old male patient accidentally ingested the BiTine ring (2 cm diameter, 0.5 cm outward projections while it was being applied to a distoproximal cavity in tooth # 19. The ring placement forceps were excessively flexible; bending of the beaks towards the ring combined with a poor no-slippage mechanism led to sudden disengagement of the ring and accelerated movement towards the pharynx. We followed the patient with bulk forming agents and radiographs. Fortunately the ring passed out without any complications.Clinical implications: Checking equipment and methods is as important as taking precautions against any preventable medical emergency. It is the responsibility of the clinician to check, verify and then use any instrument/equipment.Keywords: foreign bodies/radiography, foreign bodies/complications, equipment failure, dental instrument, accidental ingestion

    Full Text Available Aim: Carbon monoxide (CO is often referred to as the “silent killer” because its victims cannot see it, smell it or taste it. CO is responsible for a large percentage of the accidental poisonings and deaths reported throughout the world. CO poisoning therefore is considered a serious global health threat. The aim of the present study was to describe the cases of CO poisoning in a rural areas of Adana, Turkey between 2002 and 2015 based on data collected from incident reports. Methods: The cases of accidental CO poisoning were statistically analyzed. During that period, 74 incidents occurred and 154 people were poisoned by accidental CO poisoning. Results: The results of this analysis indicate that men and adults aged ≥65 years were more likely to die from CO poisoning than others. The number of CO poisoning cases was highest during the heating season. The majority (72% of poisoning resulting in hospitalization with a life-threatening condition or death occurred within the home. Conclusion: CO poisoning is a serious danger. People must be informed about this hazard. By educating risk groups about the dangers of CO poisoning, it is possible to save many lives as well as reduce the health risks.

    This study explores and describes factors that persons with multiple sclerosis (MS) perceive as being related to accidental falls. A qualitative content analysis with primarily deductive approach was conducted using the International Classification of Functioning, Disability and Health. Twelve persons with MS, and identified as fallers, were interviewed. Factors perceived to cause accidental falls that had not previously been targeted in MS populations in relation to falls were identified as divided attention, reduced muscular endurance, fatigue and heat sensitivity. Previously reported risk factors such as changed gait pattern, limited walking ability, impaired proprioception, vision and spasticity were supported. Activities involving walking, recreation and leisure, maintaining and changing body position, lifting or carrying, taking care of the home, washing the body, moving around, preparing meals and housekeeping were limited and considered to be risk activities. Supportive persons and assistive device reduced falls, and unsuitable physical environments and climate conditions induced falls. Several preventative strategies were described as partially compensating for the impairments, limitations and restrictions. Investigating accidental falls using the perspective of the patient gave important information about variables not earlier targeted in MS research.

    Among the main causes of death in our country are car accidents, drowning and accidental burns. Strangulation is a potentially fatal injury and an important cause of homicide and suicide among adults and adolescents. In children, its occurrence is usually accidental. However, in recent years, several cases of accidental strangulation in children around the world have been reported. A 2-year-old male patient was strangled in a car window. The patient was admitted to the pediatric intensive care unit with a Glasgow Coma Scale score of 8 and presented with progressive worsening of respiratory dysfunction and torpor. The patient also presented acute respiratory distress syndrome, acute pulmonary edema and shock. He was managed with protective mechanical ventilation, vasoactive drugs and antibiotic therapy. He was discharged from the intensive care unit without neurological or pulmonary sequelae. After 12 days of hospitalization, he was discharged from the hospital, and his state was very good. The incidence of automobile window strangulation is rare but of high morbidity and mortality due to the resulting choking mechanism. Fortunately, newer cars have devices that stop the automatic closing of the windows if resistance is encountered. However, considering the severity of complications strangulated patients experience, the intensive neuro-ventilatory and hemodynamic management of the pathologies involved is important to reduce morbidity and mortality, as is the need to implement new campaigns for the education of parents and caregivers of children, aiming to avoid easily preventable accidents and to optimize safety mechanisms in cars with electric windows.

    The Fukushima nuclear accident led to the most important accidental release of artificial radionuclides into the sea. This accident has underlined the importance of being able to adequately reproduce the fate of radioactive releases and to estimate their consequences for the marine environment. For its Crisis Centre, the French Institute for Radioprotection and Nuclear Safety (IRSN) has operational tools, in order to help experts and decision makers in case of any atmospheric accidental release and terrestrial environment contamination. The on-going project aims to develop tools to manage any marine contamination of the French coastal areas. We should be able to evaluate and anticipate the marine post-accidental situation: contaminated areas localization and contamination levels, and possible consequences. Many sites has be considered as potential source terms into the sea: the Coastal Nuclear Power Plants, the La Hague reprocessing Plant, the Brest and Toulon Military Harbours as home-ports of nuclear powered vessels, and different river mouths (Rhone River, Gironde, Loire, Seine) that could be contaminated by upstream accidental release. To achieve this goal, two complementary approaches are developed: Marine sheets and a dedicated modelling tool (STERNE). - Marine sheets aim to summarize marine environment characteristics for the different sites, identify potential stakes for human protection such as aquaculture areas, beaches, or industrial water intakes, and ecological stakes. Whenever possible, a local climatology (main currents depending on meteorological or tide conditions) that could be a support to first environmental measurement strategy is proposed. A list of available local contacts for any operational management is also provided. - The modelling tool, STERNE (Simulation du Transport et du transfert d'Elements Radioactifs dans l'environNEment marin), must predict radionuclide dispersion and contamination of water, marine species and sediments

In opposition to that was noted twenty years ago, the accidents don't involve only the industrial firm or hospital wage earners but also public people. Serious accident analysis puts to the fore the defects which made them possible. The accidents due to energy production reactors are very seldom even if Chernobyl or nuclear submarine accidents have exposed about several hundreds workers to doses going beyond one gray. 78 refs. 17 figs. 14 tabs. 3 annexes

    Full Text Available La oxidación de metano a metanol por medio de una forma directa, económica y con bajo gasto energético es un objetivo perseguido por la industria desde sus orígenes. El metano es el principal componente del gas natural, mientras que el metanol es combustible y materia prima en la industria química. En el presente artículo de revisión se presentan los resultados de trabajos realizados para lograr dicho proceso, identificando los aspectos más relevantes que se involucran. Se encontraron bajos valores de conversión de metano y selectividad a metanol debido, principalmente, a dos factores: el primero es la dificultad de activar el metano y, el segundo, poder controlar el proceso para evitar reacciones secuenciales de oxidación que generen otros productos. Para incrementar el rendimiento del proceso, es necesario optimizar las condiciones de síntesis de los mate-riales, incluyendo temperatura, tiempo y cargas del componente activo, lo cual influirá en el comportamiento físico y químico de los catalizadores. También es necesario controlar las variables del proceso de oxidación catalítica, como el tipo de material del reactor, flujos de alimentación, tiempos de permanencia de los gases dentro del reactor, y evitar así reacciones competitivas que disminuyan la selectividad al alcohol.

    We present the main findings of the 5th National Audit Project (NAP5) on accidental awareness during general anaesthesia (AAGA). Incidences were estimated using reports of accidental awareness as the numerator, and a parallel national anaesthetic activity survey to provide denominator data. The incidence of certain/probable and possible accidental awareness cases was ~1:19,600 anaesthetics (95% confidence interval 1:16,700-23,450). However, there was considerable variation across subtypes of techniques or subspecialities. The incidence with neuromuscular block (NMB) was ~1:8200 (1:7030-9700), and without, it was ~1:135,900 (1:78,600-299,000). The cases of AAGA reported to NAP5 were overwhelmingly cases of unintended awareness during NMB. The incidence of accidental awareness during Caesarean section was ~1:670 (1:380-1300). Two-thirds (82, 66%) of cases of accidental awareness experiences arose in the dynamic phases of anaesthesia, namely induction of and emergence from anaesthesia. During induction of anaesthesia, contributory factors included: use of thiopental, rapid sequence induction, obesity, difficult airway management, NMB, and interruptions of anaesthetic delivery during movement from anaesthetic room to theatre. During emergence from anaesthesia, residual paralysis was perceived by patients as accidental awareness, and commonly related to a failure to ensure full return of motor capacity. One-third (43, 33%) of accidental awareness events arose during the maintenance phase of anaesthesia, mostly due to problems at induction or towards the end of anaesthesia. Factors increasing the risk of accidental awareness included: female sex, age (younger adults, but not children), obesity, anaesthetist seniority (junior trainees), previous awareness, out-of-hours operating, emergencies, type of surgery (obstetric, cardiac, thoracic), and use of NMB. The following factors were not risk factors for accidental awareness: ASA physical status, race, and use or omission

    How do people respond to others' accidental behaviors? Reward and punishment for an accident might depend on the actor's intentions, or instead on the unintended outcomes she brings about. Yet, existing paradigms in experimental economics do not include the possibility of accidental monetary allocations. We explore the balance of outcomes and intentions in a two-player economic game where monetary allocations are made with a “trembling hand”: that is, intentions and outcomes are sometimes mismatched. Player 1 allocates $10 between herself and Player 2 by rolling one of three dice. One die has a high probability of a selfish outcome, another has a high probability of a fair outcome, and the third has a high probability of a generous outcome. Based on Player 1's choice of die, Player 2 can infer her intentions. However, any of the three die can yield any of the three possible outcomes. Player 2 is given the opportunity to respond to Player 1's allocation by adding to or subtracting from Player 1's payoff. We find that Player 2's responses are influenced substantially by the accidental outcome of Player 1's roll of the die. Comparison to control conditions suggests that in contexts where the allocation is at least partially under the control of Player 1, Player 2 will punish Player 1 accountable for unintentional negative outcomes. In addition, Player 2's responses are influenced by Player 1's intention. However, Player 2 tends to modulate his responses substantially more for selfish intentions than for generous intentions. This novel economic game provides new insight into the psychological mechanisms underlying social preferences for fairness and retribution. PMID:19707578

    With the continued development of nuclear power plants, more and more super-large cooling towers are to be built in China and around the world. For the safe operation of nuclear power plants, research work has been done on the causes of collapse of cooling towers, collapse modes and the secondary disasters caused by the collapse of cooling towers. However, the collapse modes and the ground vibration induced by the collapse of cooling towers subjected to the accidental loads have not been fully understood. This paper has been focused on the modes and mechanisms behavior of the collapse of cooling towers subjected to accidental loads. Meanwhile, prediction of the ground vibration due to the collapse of the cooling towers has also been completed in a parallel project. Using dynamic finite element program LS-DYNA, a 3D finite element model for a super-large cooling tower was developed and the nonlinear material models were incorporated. In this paper, four types of accidental loads were considered to trigger the collapse or local failure of the tower, including vehicle collision, airplane impact, local explosion and missile attack. It was found that vehicle collision, missile attack and small TNT equivalent explosives (2 kg, 20 kg, 200 kg) might result in local failure of the cooling tower, however, the tower can still keep stable. On the other hand, large TNT equivalent explosives (2000 kg, 4500 kg) could cause severe damages in the inclined columns of the cooling tower, and lead to progressive collapse of the entire cooling tower. The two kinds of TNT equivalent explosives caused the same collapse mode while the collapsing duration was different. The airplane impacted at the throat of the cooling tower caused the local failure of shell structure of the tower, and then the progressive collapse of the cooling tower happened due to the gravitational action. The resulting collapse mode was different from that triggered by the local explosion.

    The advance made in the nuclear security evaluation of the CAREM reactor is presented. It was carried out using the Security Probabilistic Analysis (SPA). The latter takes into account the different phases of identification and solution of initiating events and the qualitative development of event trees. The method of identification of initiating events is the Master Logical Diagram (MLD), whose deductive basis makes it appropriate for a new design like the one described. The qualitative development of the event trees associated to the identified initiating events, allows identification of those accidental sequences which are to have the security systems in the reactor.

    This paper focuses on uncertainties in model output used to assess accidents. We begin by reviewing the historical development of assessment models and the associated interest in uncertainties as these evolutionary processes occurred in the United States. This is followed by a description of the sources of uncertainties in assessment calculations. Types of models appropriate for assessment of accidents are identified. A summary of results from our analysis of uncertainty is provided in results obtained with current methodology for assessing routine and accidental radionuclide releases to the environment. We conclude with discussion of preferred procedures and suggested future directions to improve the state-of-the-art of radiological assessments

In addition, in several cases there is a need to identify the prior presence of radioactive materials at buildings or sites (nuclear forensics). To this direction, several materials have been the research object of numerous studies the last decade in an attempt to identify potentially new retrospective/accidental/forensic dosimeters. However, the studies targeting biological materials are limited and their majority is mainly focused on the luminescence behavior of human biological material. Consequently, the use of such materials in retrospective dosimetry presumes the exposure of humans in the radiation field. The present work constitutes the first attempt to seek non-human biological materials, which can be found in nature in abundance or in/on other living organisms. To this end, the present work investigates the basic optically stimulated luminescence behavior of insect wings, which exhibit several advantages compared to other materials. Insects are ubiquitous, have a short life expectancy and exhibit a low decomposition rate after their death. Findings of the present study are encouraging towards the potential use of insects' wings at retrospective/accidental/forensic dosimetry, since they exhibit linear OSL response over a wide dose range and imperceptible loss of signal several days after their irradiation when they are kept in dark. On the other hand, the calculated lower detection limit is not low enough to allow their use as emergency dosimeters when individuals are exposed to non-lethal doses. In addition, wings exhibit strong optical fading when they are exposed to daylight and thus special care should be taken during the sampling procedure in order to use the wings as accidental/forensic dosimeters, by seeking (dead) insects in dark places, such as behind furniture, equipment or in

    1999-01-01

    The computer program UFOTRI can be used for assessing the impact of accidental released tritium in the two chemical forms tritiated water vapour and tritium gas. By applying UFOTRI to potential European sites for ITER, it could be demonstrated that the main goal, the nonevacuation criteria, is fulfilled for the present release limits. Contributions in international studies together with the re-evaluation of experimental data showed that the plant sub-model as well as the soil sub-model are areas for further improvement. (author)

  16. Comparison of numerical models for calculating dispersion from accidental releases of pollutants

    Energy Technology Data Exchange (ETDEWEB)

    Pepper, D W [Savannah River Lab., Aiken, SC; Cooper, R E; Baker, A J

    1982-01-01

    A modular, data-based system approach has been developed to facilitate computational simulation of multi-dimensional pollutant dispersion in atmospheric, steam, estuary, and groundwater applications. This system is used to assess effects of accidental releases of pollutants to the environment. Model sophistication ranges from simple statistical to complex three-dimensional numerical methods. The system used specifies desired degree of model sophistication from a terminal. The model used depends on the particular type of problem being solved, and on a basis of merit related to computer cost. The results of prediction for several model problems are presented.

    The incidence of hypothermia is difficult to evaluate, and the data concerning the morbidity and mortality rates do not seem to fully represent the problem. The aim of the study was to estimate the actual prevalence of accidental hypothermia in Poland, as well as the methods of diagnosis and management procedures used in emergency rooms (ERs). A specially designed questionnaire, consisting of 14 questions, was mailed to all the 223 emergency rooms (ER) in Poland. The questions concerned the incidence, methods of diagnosis and risk factors, as well as the rewarming methods used and available measurement instruments. The analysis involved data from 42 ERs providing emergency healthcare for the population of 5,305,000. The prevalence of accidental hypothermia may have been 5.05 cases per 100.000 residents per year. Among the 268 cases listed 25% were diagnosed with codes T68, T69 or X31, and in 75% hypothermia was neither included nor assigned a code in the final diagnosis. The most frequent cause of hypothermia was exposure to cold air alongside ethanol abuse (68%). Peripheral temperature was measured in 57%, core temperature measurement was taken in 29% of the patients. Peripheral temperature was measured most often at the axilla, while core temperature measurement was predominantly taken rectally. Mild hypothermia was diagnosed in 75.5% of the patients, moderate (32-28°C) in 16.5%, while severe hypothermia (less than 28°C) in 8% of the cases. Cardiopulmonary resuscitation was carried out in 7.5% of the patients. The treatment involved mainly warmed intravenous fluids (83.5%) and active external rewarming measures (70%). In no case was extracorporeal rewarming put to use. The actual incidence of accidental hypothermia in Polish emergency departments may exceed up to four times the official data. Core temperature is taken only in one third of the patients, the treatment of hypothermic patients is rarely conducted in intensive care wards and extracorporeal rewarming

    Intoxication with Aconitum napellus is rare in our regions. Aconite alkaloids can cause ventricular arrhythmia by a prolonged activation of sodium channels. Because the margin of safety is low between the analgesic and toxic dose, intoxication is not rare when Aconite is used in herbal medicine. We present a case in which a 39-year-old male was accidentally intoxicated with Aconite. Even though no antidote or adequate therapy is available he was successfully resuscitated.

    Full Text Available Non-accidental deaths in children in Kuala Lumpur, Malaysia are not uncommon, and they are often reported for identification of injuries. Five case series in children are presented here with typical injuries of differing ages in child abuse. Where history was partially hidden from the real scenario, involvement of family members was inevitable. The injuries were particularly diversified from a single unprecedented injury to multiple severe injuries, which led to the deaths of children less than 3 years of age. The discussion revolved around the autopsy and ancillary investigations in the context of urban perspectives in Kuala Lumpur area.

    Cannabis intoxication in toddlers is rare and mostly accidental. Our objectives were to focus on the characteristics and management of children under the age of 6 years who were admitted to our emergency department with cannabis poisoning reported as accidental by parents, and to point out the need to consider accidental cannabis ingestions as an indicator of neglect. The medical records of children hospitalized for cannabis poisoning in a pediatric emergency department from January 2007 to November 2012 were retrospectively evaluated. Data collected included age, sex, drug ingested, source of drug, intentional versus accidental ingestion, pediatric intensive care unit or hospital admission, treatment and length of hospital stay, toxicology results, and rate of child protectives services referral. Twelve toddlers (4 boys and 8 girls; mean age, 16.6 months) were included. All had ingested cannabis. Their parents reported the ingestion. Seven children experienced drowsiness or hypotonia. Three children were given activated charcoal. Blood screening for cannabinoids, performed in 2 cases, was negative in both, and urine samples were positive in 7 children (70%). All children had favorable outcomes after being hospitalized from 2 to 48 hours. Nine children were referred to social services for further assessment before discharge. Cannabis intoxication in children should be reported to child protection services with the aim of prevention, to detect situations of neglect and at-risk families. Legal action against the parents may be considered. Accidental intoxication and caring parents should be no exception to this rule.

    1995-01-01

    The accidental coincidences of a measuring system based on time-to-amplitude conversion are considered in some detail for the case of low starting and high stopping rates. Two types of accidental coincidences are distinguished, those carrying time information and those without time information. Neglecting any deadtime effects of the detectors, analytical expressions for the calculation of the time distribution of the random coincidences are evaluated. The analytical expressions have been confirmed by Monte Carlo simulations. The procedure is applied to time-differential Moessbauer spectroscopy in order to extract the time spectra of true coincidences. The measured spectrum in a time channel turns out to be a superposition of the true spectrum (true coincidences), a time integral spectrum (random coincidences), and a weighted superposition of true spectra of other time channels (random but time carrying information). A measurement with a single line 57 Co/Rh-source and single line K[Fe(CN) 6 ].3H 2 O-absorber with stopping rates of 1 MBq shows agreement between the theoretical time-filtered spectra and the corrected measured spectra of true coincidences.

    2003-01-01

    The paper focuses on experimental analysis of nuclear criticality safety at accidental water immersion of fuel elements of the Russian TOPAZ-2 space nuclear power system reactor. The structure of water-moderated heterogeneous critical assemblies at the NARCISS facility is described in detail, including sizes, compositions, densities of materials of the main assembly components for various core configurations. Critical parameters of the assemblies measured for varying number of fuel elements, height of fuel material in fuel elements and their arrangement in the water moderator with a uniform or variable spacing are presented. It has been found from the experiments that at accidental water immersion of fuel elements involved, the minimum critical mass equal to approximately 20 kg of uranium dioxide is achieved at 31-37 fuel elements. The paper gives an example of a physical model of the water-moderated heterogeneous critical assembly with a detailed characterization of its main components that can be used for calculations using different neutronic codes, including Monte Carlo ones.

    Simmonds, J.R.; Haywood, S.M.; Linsley, G.S.

    1982-10-01

    The long term consequences of land contamination from accidental releases of activity from thermal reactors are examined. The radiological consequences are assessed using an analysis of the exposure of individuals and the population to ground deposits of the radionuclides released. The contribution of the different nuclides in the release by their various exposure routes to the irradiation of man are calculated as a function of time after release and the most radiologically important are identified. A preliminary assessment is made of off-site economic and social consequences of accidental releases by estimating the areas of land which would be affected by the introduction of countermeasures to control individual radiation exposure due to external irradiation from ground deposits (relocation of populations), and the intake of radionuclides contained in locally produced foodstuffs (restrictions on food production). The areas where administrative controls would be necessary decline in size with time after the release; estimates are made of this time-dependent behaviour using dynamic environmental transfer models. Finally, the collective doses saved by the introduction of countermeasures are estimated using population and agricultural distribution data for a rural location in the United Kingdom. (author)

    Bivalve molluscan shellfish such as oysters may be contaminated by human pathogens. Currently, the primary pathogens associated with shellfish-related outbreaks are noroviruses. This study was conducted to improve understanding of oyster bioaccumulation when oysters were exposed to daily contamination or one accidental contamination event, i.e., different modes of contamination. Oysters were contaminated with two representative strains of norovirus (GI.1 and GII.3) and then analyzed with real-time reverse transcription PCR. Exposure to a repeated virus dose for 9 days (mimicking a growing area subjected to frequent sewage contamination) led to an additive accumulation that was not significantly different from that obtained when the same total dose of virus was added all at once (as may happen after accidental sewage discharge). Similarly, bioaccumulation tests performed with mixed strains revealed additive accumulation of both viruses. Depuration may not be efficient for eliminating viruses; therefore, to prevent contaminated shellfish from being put onto the market, continuous sanitary monitoring must be considered. All climatic events or sewage failures occurring in production areas must be recorded, because repeated low-dose exposure or abrupt events may lead to similar levels of accumulation. This study contributes to an understanding of norovirus accumulation in oysters and provides suggestions for risk management strategies.

    The construction sector is associated with various accidents and fatal injuries. These occupational accidents are caused by numerous factors, such as lack of supervision; lack of adherence to safe work technique; failure to wear personal protective equipment; and failure to comply with the safe use of tools, vehicles, and machines. Using 2013–2016 secondary data from the Department of Occupational Safety and Health and Social Security Organization, this study conducted a descriptive exploration survey to identify common fatal occupational injuries associated with the Malaysian construction sector, as well as their causes and accidental agents. Results indicated that construction, followed by manufacturing, agriculture, forestry, logging, and fishery, are the riskiest job sectors in Malaysia. The highest incidences of occupational casualties were reported in Sarawak, Johor, and Selangor. These states accounted for approximately 13.33% to 18.18% of all cases of fatal occupational accidents. In these states, the lack of safety and health regulations and poor execution of risk management increased the risk of occupational accidents. Falls from heights accounted for 46.28% of fatal occupational injuries. Furthermore, being crushed by objects, materials, or vehicles accounted for 9.09% to 17.36% of fatal occupational injuries. Substandard work environment and transportation and lifting equipment, such as scaffolds, are primary accidental agents. Results of this study could enhance the knowledge and awareness of construction workers and management of job-related injuries to decrease the incidence of fatal occupational accidents.

The objective of the study was a retrospective evaluation of patients hospitalized in the Paediatric Clinic during the period 2004–2012 due to poisoning with paracetamol.The analysis covered 44 patients hospitalized in the Paediatric Clinic during 2004–2012 due to poisoning with paracetamol. Patients were divided into three groups: intentional poisonings, accidental poisonings, and drug overdose.During the period of the study, 44 patients aged 2.1–17.1, poisoned with paracetamol, were hospitalized. Among these patients there were 30 (68.2% cases of intentional poisonings, 10 (22.7% of accidental poisonings, and only 4 patients (9.1% were children hospitalized after a paracetamol overdose. The majority of patients in all groups were females (93.3%.Paracetamol intoxication may occur after exceeding a single allowable dose, in the case of intentional poisoning, more rarely after exceeding the daily dose, in the case of intense pain complaints, or in the treatment of persistent fever.Based on the analysis performed, an increase was observed in the frequency of poisoning with paracetamol, especially intentional poisoning. Unlimited access to paracetamol as an OTC drug should be reconsidered.

    Rib fractures in children under the age of 2 years have a strong correlation with non-accidental injury (NAI). Follow-up radiographs can improve detection. To evaluate the value of the follow-up chest radiograph in suspected non-accidental injury. The study included all children less than 2 years of age who were investigated for suspected NAI in our institution between January 1998 and October 2003. Prior to January 2000, only selected patients were asked to attend for a follow-up chest radiograph. From January 2000 onwards all children were asked to reattend. Of 200 children included in the study, 59 (29.5%) reattended for a follow-up chest radiograph. The follow-up film provided useful additional information in 7 (12%) of the 59 children. In two children rib fractures were noted only on the follow-up chest radiograph. In a further two patients additional rib fractures were noted. Additional dating information was obtained for two patients. For one child both additional fractures and dating information were noted. The follow-up chest radiograph provides useful information in children with suspected NAI and it is recommended that it should be included routinely in the imaging investigations of these children.

    The World Association of Veterinary Food Hygienists (WAVFH) held an international round table conference in Stockholm, Sweden, January 26-29, 1987. The topic of the conference was 'Accidental Radiation Contamination of Food of Animal Origin'. The agenda was divided into three major topic areas: 1. Ecological Science; 2. Veterinary Science - Live Animals; and 3. Veterinary Science - Food of Animal Origin. Experts and delegates from member countries presented papers, participated in discussions and workshops and produced a multidisciplinary report covering the topic areas. The recent accidental release of radioactive substances into the environment from the Chernobyl accident, demonstrated the need for veterinary, ecological, physical and medical sciences to be prepared to respond to an incident in order to protect the environment, food chain, other agricultural assets and humans from the adverse effects of radionuclides. Several presentations suggested that even with the best technologies, national and regional commitment, and relatively unrestricted resource levels, nuclear incidents can cross international boundaries and can contaminate the environment to the extent that the integrity of various food and water supplies can be at risk. Speakers and subsequent discussers tended to concentrate on the issues associated with lessening future environmental impacts if similar types of incidents should occur again.

    Full Text Available Here, authors present a review on clinical presentation and management of exposure of phosgene gas after reviewing the literature by searching with keywords phosgene exposure on Google, Cochrane, Embase and PubMed with a background of experience gained from 10 patients who were admitted to our institute after an accidental phosgene exposure in February 2011 nearby a city in India. Phosgene is a highly toxic gas, occupational workers may have accidental exposure. The gas can also be generated inadvertently during fire involving plastics and other chemicals and solvents containing chlorine, which is of concern to emergency responders. Phosgene inhalation may cause initially symptoms of respiratory tract irritation, patients feel fine thereafter, and then die of choking a day later because of build up of fluid in the lungs (delayed onset non-cardiogenic pulmonary edema. Phosgene exposure is associated with significant morbidity and mortality. Patients with a history of exposure should be admitted to the hospital for a minimum of 24 h for observation because of the potential for delayed onset respiratory failure and acute respiratory distress syndrome.

  7. Accidental pollution in the ocean: besides crude oil, chemicals and other spills

    Accidental pollution of the seas is usually illustrated by the shipwreck of tankers carrying crude oil. We must look beyond this image since such accidents spill substances other than petrochemicals. We need but mention the Levoli Sun's accident near the Cotentin peninsula, France, one year after the Erika went down. And what about spills of agricultural and food products? An accidental spill as apparently harmless as wheat might have serious effects on not just the environment but also human health. In all cases, two major series of questions crop up: 1) Is it necessary to intervene? If so, are we able to? And if we can, how to fight against spills? 2) What are the short- and long-term effects on the environment and on all human activities related to the sea (fishing, fish-farming, salt production, tourism, salt-water cures, etc.)? These two questions have a common denominator: the need to know how spilled products react. This knowledge conditions both the operational response for fighting against pollution and the assessment of the impact on the maritime environment. (author)

    Full text: The current social and political situation in many world areas and the increasing hostilities between countries and cultures have accentuated the risk of a malicious use of ionising radiations. Terrorist attacks with the intentional disseminations of radioactive materials in urban settlements may involve a large number of persons, and a rapid estimation of the severity of the exposure is required for undertaking suitable protective actions and supporting decision making. Promising methodologies for a prompt dose evaluation, are those exploiting the luminescence and dosimetric properties of objects and materials which can be easily found in the contaminated area. Among these objects, dental materials have the advantage to be on contact with human body and they could therefore represent individual dosimeters in case of accidental exposure to ionising radiation. The interest in the use of dental ceramics for dosimetric purposes dates back to late 1970, however, it is only through the use of high-sensitive experimental techniques and instrumentation today available, that the potentiality of such materials as accidental dosimeters can be exploited. Moreover, innovative materials are being continuously introduced into the market, containing new additives and pigments with peculiar optical properties. In this study, Thermally Stimulated Luminescence (TSL) and Optically Stimulated Luminescence (OSL) techniques are applied to investigate the luminescence and dosimetric properties of several dental materials, including resins, glass and feldspatic ceramics, and also zirconia and alumina based ceramics, being their use widely increased in the recent years in substitution of metal cores.

    Highlights: • Reference accidental situations for current and future reactors are considered. • They require the modeling of complex fluid–structure systems at full reactor scale. • EPX software computes the non-linear transient solution with explicit time stepping. • Focus on the parallel hybrid solver specific to the proposed coupled equations. - Abstract: This contribution is dedicated to the latest methodological developments implemented in the fast transient dynamics software EUROPLEXUS (EPX) to simulate the mechanical response of fully coupled fluid–structure systems to accidental situations to be considered at reactor scale, among which the Loss of Coolant Accident, the Core Disruptive Accident and the Hydrogen Explosion. Time integration is explicit and the search for reference solutions within the safety framework prevents any simplification and approximations in the coupled algorithm: for instance, all kinematic constraints are dealt with using Lagrange Multipliers, yielding a complex flow chart when non-permanent constraints such as unilateral contact or immersed fluid–structure boundaries are considered. The parallel acceleration of the solution process is then achieved through a hybrid approach, based on a weighted domain decomposition for distributed memory computing and the use of the KAAPI library for self-balanced shared memory processing inside subdomains

    Highlights: • This paper presents transient CFD analyses on the cooling channels of the DEMO HCPB FW for accidental scenarios LOCA and LOFA. • In both LOCA & LOFA, the wall temperature increases quickly to an unacceptable level within seconds. • If the coolant flow rate is maintained at a half of nominal value in case of LOFA (partial LOFA), the wall temperature rises much slower, but will still leads to a damage of structure within minutes. • The simulated heat transfer coefficients were compared with empirical correlations. - Abstract: Helium Cooled Pebble Bed (HCPB) blanket concept is one of the DEMO (Demonstration Power Plant) blanket concepts running for the final DEMO design selection. In this paper, transient analyses on the cooling channels of the FW are carried out by means of CFD simulations for the selected accidental scenarios loss-of-coolant-accident (LOCA) and loss-of-flow-accident (LOFA). ANSYS-CFX is used for the simulations. The simulation results help to understand how fast the temperature of the FW can increase and what is the time window that is available until the temperature of the structural material reaches the design limit in order to be able to define a suitable protection strategy for the system. In view of later developments of the models, the heat transfer coefficients calculated with CFD are compared with the values predicted by two widely used correlations for turbulent pipe flows.

    Attention Deficit Hyperactivity Disorder (ADHD) is a frequent neurodevelopmental disorder that increases accidental risk. Recent studies show that some patients with ADHD can also suffer from excessive daytime sleepiness but there are no data assessing the role of sleepiness in road safety in patients with ADHD. We conducted an epidemiological study to explore sleep complaints, inattention and driving risks among automobile drivers. From August to September 2014, 491186 regular highway users were invited to participate in an Internet survey on driving habits. 36140 drivers answered a questionnaire exploring driving risks, sleep complaints, sleepiness at the wheel, ADHD symptoms (Adult ADHD Self-Report Scale) and distraction at the wheel. 1.7% of all drivers reported inattention-related driving accidents and 0.3% sleep-related driving accidents in the previous year. 1543 drivers (4.3%) reported ADHD symptoms and were more likely to report accidents than drivers without ADHD symptoms (adjusted OR = 1.24, [1.03-1.51], p 15) versus 3.2% of drivers without ADHD symptoms and 20.5% reported severe sleepiness at the wheel versus 7.3%. Drivers with ADHD symptoms reported significantly more sleep-related (adjusted OR = 1.4, [1.21-1.60], p attentional deficits and sleepiness at the wheel in these drivers. Road safety campaigns should be improved to better inform drivers of these accidental risks.

    The objective of this study consists in evaluating the sensitivity of the first part of the die grass-milk with respect to an accidental radioactive discharge. We want to know if a single uniform deposit would involve a contamination of the grazing grass identical on the scale of the own territory. The study was based on the A.S.T.R.A.L. model, a computer code developed by the I.R.S.N. which makes it possible to evaluate the transfer of the radionuclides in the terrestrial food chain following an accidental atmospheric emission. The way of transfer of A.S.T.R.A.L. on which the study focused is the transfer of the deposit to milk, via the grazing grass ingestion. The sensitivity of this way of transfer relies on several parameters: captation, yield, cows food rates and dates of setting to grass. Methodology thus consisted in regionalizing these parameters. The software S.T.I.C.S. developed by the I.N.R.A. of Avignon was then used. This model proposes a daily follow-up of the leaf area index which has been correlated with captation and with the production of fresh biomass (yield). (authors)

  14. Postprocessing of Accidental Scenarios by Semi-Supervised Self-Organizing Maps

    Full Text Available Integrated Deterministic and Probabilistic Safety Analysis (IDPSA of dynamic systems calls for the development of efficient methods for accidental scenarios generation. The necessary consideration of failure events timing and sequencing along the scenarios requires the number of scenarios to be generated to increase with respect to conventional PSA. Consequently, their postprocessing for retrieving safety relevant information regarding the system behavior is challenged because of the large amount of generated scenarios that makes the computational cost for scenario postprocessing enormous and the retrieved information difficult to interpret. In the context of IDPSA, the interpretation consists in the classification of the generated scenarios as safe, failed, Near Misses (NMs, and Prime Implicants (PIs. To address this issue, in this paper we propose the use of an ensemble of Semi-Supervised Self-Organizing Maps (SSSOMs whose outcomes are combined by a locally weighted aggregation according to two strategies: a locally weighted aggregation and a decision tree based aggregation. In the former, we resort to the Local Fusion (LF principle for accounting the classification reliability of the different SSSOM classifiers, whereas in the latter we build a classification scheme to select the appropriate classifier (or ensemble of classifiers, for the type of scenario to be classified. The two strategies are applied for the postprocessing of the accidental scenarios of a dynamic U-Tube Steam Generator (UTSG.

    Two patients with polycythemia vera received intravenously an accidental tenfold overdosage of radiophosphorus therapy (60 and 50 mCi 32P, respectively). In both patients, the occurrence of hemorrhagic complications 3 wk after the 32P medication led to detection of the error and referral to our hospital. Upon admission they showed an agranulocytosis, severe thrombocytopenia, and bone marrow aplasia. In both cases, spontaneous recovery of the hematopoiesis was observed from day 40 posttreatment onward. In one patient, a slow but ultimately complete normalization of blood counts and marrow morphology took place, whereas in the other, a mild thrombocytopenia persists. Nearly 5 yr after the accidental overdosage, both patients are clinically well. Symptoms of polycythemia vera have not reappeared up to now. Attempts were made to evaluate the radiation dose absorbed by the bone marrow. In the first patient, the daily 32P excretion was determined from day 22 to day 60, whereas in the other patient a whole body count was performed on day 78 after administration. From these results, an approximate cumulative bone marrow dose of 10 Sv (1000 rem) could be calculated

    Few studies have been published to demonstrate tolerability and efficacy of almotriptan in adolescents and children with migraine, particularly in the first years of life, though preliminary results are favorable. We report the case of an 18-month-old infant with elevation of serum levels of creatin-kinase after the accidental ingestion of almotriptan. A previously healthy 18-month-old girl (weight: 13 kg) was admitted to our Department four hours after the accidental ingestion of 6.25 mg of almotriptan (0.48 mg/kg), without any specific symptom. The performed investigations showed high serum levels of creatin-kinase (CK) (527 IU/L; normal values: 24-170 IU/L). Transaminase, creatinine, aldolase, myoglobin and troponin T serum levels were normal. The electrocardiogram proved negative. Initial management consisted of parenteral rehydration with saline solution. CK levels lowered significantly at 12 hours (455 IU/L) and at 65 hours (188 IU/L) after the ingestion. No symptoms were observed before discharge and on follow-up.

Conclusion. The combination of intrinsic and extrinsic factors that include the environmental risks is considered a much more relevant cause to occur the new falls. The minimization of the home dangers, allied to the control of the elder intrinsic factors, may reduce the risks of causes. In that sense, is necessary that the nursing team make available more attention to the elderly assisted at the ambulatories, mainly those with sequelae due to fall accidents.

    The recent expansion of biocontainment laboratory capacity in the United States has drawn attention to the possibility of occupational exposures to BSL-3 and -4 agents and has prompted a reassessment of medical management procedures and facilities to deal with these contingencies. A workshop hosted by the National Interagency Biodefense Campus was held in October 2007 and was attended by representatives of all existing and planned BSL-4 research facilities in the U.S. and Canada. This report summarizes important points of discussion and recommendations for future coordinated action, including guidelines for the engineering and operational controls appropriate for a hospital care and isolation unit. Recommendations pertained to initial management of exposures (ie, immediate treatment of penetrating injuries, reporting of exposures, initial evaluation, and triage). Isolation and medical care in a referral hospital (including minimum standards for isolation units), staff recruitment and training, and community outreach also were addressed. Workshop participants agreed that any unit designated for the isolation and treatment of laboratory employees accidentally infected with a BSL-3 or -4 pathogen should be designed to maximize the efficacy of patient care while minimizing the risk of transmission of infection. Further, participants concurred that there is no medically based rationale for building care and isolation units to standards approximating a BSL-4 laboratory. Instead, laboratory workers accidentally exposed to pathogens should be cared for in hospital isolation suites staffed by highly trained professionals following strict infection control procedures.

    Non-Accidental Trauma (NAT) is a significant cause of childhood morbidity and mortality, causing 50% of trauma-related deaths at our institution. Our purpose was to evaluate the necessity of primary surgical evaluation and admission to the trauma service for children presenting with NAT. We reviewed all NAT patients from 2007-2011. Injury types, demographic data, and hospitalization information were collected. Comparisons to accidental trauma (AT) patients were made using Wilcoxon rank sum and Student's t tests. We identified 267 NAT patients presenting with 473 acute injuries. Injuries in NAT patients were more severe than in AT patients, and Injury Severity Scores, ICU admission rates, and mortality were all significantly (pinjury were seen in patients with closed head injuries (72%), extremity fractures (51%), rib fractures (82%), and abdominal/thoracic trauma (80%). Despite these complex injury patterns, only 56% received surgical consults, resulting in potential delays in diagnosis, as 24% of abdominal CT scans were obtained >12 hours after hospitalization. Given the high incidence of polytrauma in NAT patients, prompt surgical evaluation is necessary to determine the scope of injury. Admission to the trauma service and a thorough tertiary survey should be considered for all patients. Copyright © 2013 Elsevier Inc. All rights reserved.

    Corrosion, Fatigue and Irradiation embrittlement are the major degradation mechanisms responsible for ageing of RPV (and its internals) of a Pressurized Water Reactor. While corrosion and fatigue can generate cracks, irradiation damage can lead to brittle fracture initiating from these cracks. Ageing in nuclear power plants needs to be managed so as to ensure that design functions remain available throughout the life of the plant. From safety perspective, this implies that ageing degradation of systems, structures and components important to safety remain within acceptable limits. Reactor Pressure Vessel has been identified as the highest priority key component in plant life management for Pressurized Water Reactors. Therefore special attention is required to ensure its structural integrity during its lifetime. In this paper, structural integrity assessment for typical VVER-1000 RPV is carried out under severe accidental cool down transients using the Finite Element Method. Three different accidental scenarios are postulated and safety of the vessel is conservatively assessed under these transients using the Linear Elastic Fracture Mechanics approach. Transient thermo mechanical stress analysis of the core belt region of the RPV is carried out in presence of postulated cracks and stress intensity factors are calculated and compared with the material fracture toughness to assess the structural integrity of the vessel. The paper also include some parametric analyses to justify the methodology. (author)

    Full Text Available The traditional approach to infrastructural safety follows the consideration of mitigation tools, such as the identification and management of black spots or road sections with high accident concentration, or preventing tools, as road safety audits and inspections. A complement to these tools is presented in this paper, from a new perspective: the consideration of road sections where, under similar conditions and similar risk exposure, there are no accidents (white road sections. A model has been calibrated to the Spanish toll motorways network, identifying the specific geometric parameters and traffic characteristics which have the highest influence in the occurrence of white sections with sufficient length, without accidents during a significant period of time: heavy vehicles traffic volume, with of the road section and speed.El planteamiento tradicional de análisis de la accidentalidad en carretera pasa por la consideración de herramientas paliativas, como son la identificación y gestión de los puntos negros o tramos de concentración de accidentes, o preventivas, como las auditorías o inspecciones de seguridad vial. En este artículo se presenta un complemento a estas herramientas, desde una perspectiva novedosa: la consideración de los tramos donde, bajo unas condiciones similares a las de otros tramos y una similar exposición al riesgo, no se producen accidentes (tramos blancos. Se resume el modelo que se ha calibrado para las autopistas de peaje españolas, identificando los parámetros específicos de la geometría de la vía y del tráfico que más influencia tienen en el hecho de que en algunos tramos de suficiente longitud, no se produzcan accidentes durante un periodo significativo de tiempo: el tráfico de pesados, al ancho de calzada y la velocidad de circulación.

    Full Text Available An important phase of endodontic treatment is the irrigation of the root canal system. Desirable functions of irrigation are antimicrobial activity, dissolution of necrotic tissue, and non toxicity to the periradicular tissue. Toxicity of NaOCl solution on vital tissue is still controversial. Severe complications may occur if this solution is inadvertently exposed to the oral mucosa, and it is very hazardous. The purpose of this paper is to caution dentists on the hazards of using NaOCl irrigation in endodontic treatment. A case is presented in which 2.5% NaOCl solution was accidentally streaming into the patient's throat because the irrigating needle was not securely attached to the syringe, with the result that the patient had difficulty in breathing. The patient was promptly taken to a pulmonologist, internist, and ENT. The patient was given dexamethasone 10 mg iv injection, delladryl 1 cc iv, and nebulizer with 1 ampoule of steroid, 1 ampoule of ventolin and 5 cc NaCl 3x within 24 hours, and after 24 hours the condition was increased. From this case it is concluded that the 2.5% NaOCl solution is very alkaline and irritating, resulting in deem of the larynx and plugging up of the respiratory system. Clinicians need to be cautious in using NaOCl solution to avoid endangering the patient's life.

    Strangulation is generally considered as homicidal death and in accidental strangulation circumstantial evidence alone can point toward the accidental nature of incidence. In present case, a 71-year-old woman, wearing a saree (garment worn by traditional women in India) working in agricultural field, got entangled in the crop thrasher machine and got strangled. Immediately, she was taken to the nearest hospital, where she survived for 6 to 8 hours and then died. The autopsy reveals cross ribbon-shaped ligature mark on neck and anterior chest along with 1 puncture wound at the right lateral aspect of the neck. A lack of proper precaution and safety measures at agricultural field are other contributing factors. Accidental strangulation by saree is extremely rare, hence, this case is presented for its rarity and pattern of injury.

    Positron emission mammography (PEM) has begun to show promise as an effective method for the detection of breast lesions. Due to its utilization of tumor-avid radiopharmaceuticals labeled with positron-emitting radionuclides, this technique may be especially useful in imaging of women with radiodense or fibrocystic breasts. While the use of these radiotracers affords PEM unique capabilities, it also introduces some limitations. Specifically, acceptance of accidental and Compton-scattered coincidence events can decrease lesion detectability. The authors studied the effect of accidental coincidence events on PEM images produced by the presence of 18F-Fluorodeoxyglucose in the organs of a subject using an anthropomorphic phantom. A delayed-coincidence technique was tested as a method for correcting PEM images for the occurrence of accidental events. Also, a Compton scatter correction algorithm designed specifically for PEM was developed and tested using a compressed breast phantom.

However the yield of double-read is unknown. To determine the advantage of double-read versus single-read of radiographic skeletal surveys for suspected non-accidental trauma. The study was performed in two phases. In the first phase (April 2013 to September 2013), double-read was performed for all skeletal surveys obtained during weekday working hours. Because we had no new double-read findings in studies initially read as negative, we conducted a second phase (January 2014 to March 2014). In the second phase we limited double-reads to skeletal surveys found positive on the first read. At the end of this period, we retrospectively performed double-read for all initially negative skeletal surveys. We excluded follow-up skeletal surveys. The difference in discrepancy (new fracture or false diagnosis of a fracture) ratio between negative and positive skeletal surveys was evaluated using the Fisher exact test, and change in discrepancy ratio between the first and second study phases was evaluated using the stratified Cochran-Mantel-Haenszel test. Overall in the two phases, 178 skeletal surveys were performed in 178 children (67 girls) with mean age of 9 months (range 3 days to 3.7 years). Double-read found 16 discrepancies in 8/178 (4.5%) skeletal surveys. Seven of these studies showed additional fractures (n=15). In one study, an initial read of a skull fracture was read as a variant on the second read. There was a significant (P=0.01) difference between rate of disagreement in negative skeletal surveys (1/104, 1.0%) and positive skeletal surveys (7/74, 9.5%). No significant change in disagreement rate was demonstrated between the two phases of the study (P=0.59).

    In urban settings where humans interact in complex ways with ecosystems, there may be hidden or unanticipated benefits (services) or harm (disservices) conferred by the built environment. We examined interactions of a highly vulnerable population, the homeless, with urban waterways and wetlands in the desert city of Phoenix, Arizona, U.S.A. Climate change models project increases in heat, droughts, and extreme floods for the southwestern U.S. These projected changes pose a number of problems for sustainability and quality of future water supply, and the ability of human populations to mitigate heat stress and avoid fatalities. Urban wetlands that are created "accidentally" (by water pooling in abandoned areas of the landscape) have many structural (e.g., soils and hydrology) and functional (e.g., high denitrification) elements that mimic natural, unaltered aquatic systems. Accidental wetland systems in the dry bed of the Salt River, fed by storm and waste water from urban Phoenix, are located within economically depressed sections of the city, and show the potential for pollutant and heat mitigation. We used a mixed-method socio-ecological approach to examine wetland ecosystem functions and the ways in which homeless populations utilize Salt River wetlands for ecosystem services. Interviews and trash surveys indicated that homeless people are accessing and utilizing the wetlands as a source of running water, for sanitary and heat mitigation services, and for recreation and habitation. Environmental monitoring demonstrated that the wetlands can provide a reliable source of running water, nutrient and pathogen removal, heat mitigation, and privacy, but they may also pose a health risk to individuals coming in contact with the water through drinking or bathing. Whether wetlands provided a net benefit vs. harm varied according to site, season, and particular service, and several tradeoffs were identified. For example, heat is highest during the summer storm season

    Full Text Available As the result of the Chernobyl NPP accident more than 200 thousand square kilometers of the European territories were contaminated by Cs-137 in the amount of above 37 kBq/m2 (1 Ci/km2 . Belorussia, Russia and Ukraine amount up to 70% of this entire affected area. More than 600 000 people were engaged in the accidental cleanup operations, 340000 were evacuated or relocated within 1986-1991. The early stage evacuation efficacy is confirmed by the absence of acute radiation syndrome among the population and by the prevented collective dose which amounts to no less than 10 000 man/Sv. The effective measure to reduce the internal radiation dose to the population at the early accidental stage was introduction of maximum tentative permissive levels of radionuclide content in the foodstuffs.Among the identified post -accident medical consequences of the Chernobyl is the radiation syndrome found in 134 emergency cleanup workers within the first 24 hours of the accident’s development. Out of that number, 28 people died within the first four months, 19 people died before 2006. The accident’s liquidators developed radiation -induced leukemia ( the attributive risk value is 45-60% . People exposed to high radiation doses display the statistically significant 18% morbidity increase of all types of solid cancers at the doses above 150 mSv. There is the statistically significant information indicating the increased amount of thyroid cancer morbidity among those who were just children and teenagers at the time of the accident. The adverse psychological consequences are accounted for not just the fear of overexposure but also for the disturbance of the habitual lifestyle especially mindful of the forced relocation.The longterm protection measures, radionuclide decay and selfcleaning of the contaminated areas resulted in the drastic reduction of the population dose in the radioactively contaminated territories. In 2015, only in some settlements of the Briansk

  2. Malignant Cerebellar Edema Subsequent to Accidental Prescription Opioid Intoxication in Children

    Directory of Open Access Journals (Sweden)

    Daniel Duran

    2017-07-01

    Full Text Available We present two recent cases of toddlers who developed malignant cerebellar edema subsequent to accidental ingestion of prescription opioids. Both children presented acute neurological decline, hydrocephalus, and tonsillar herniation requiring emergent ventricular drain placement, suboccipital craniectomy, and partial cerebellectomy. Together with several other reports, these cases suggest the existence of an uncommon yet severe syndrome of acute opioid-induced malignant cerebellar edema. We hypothesize that the condition results from a combination of primary opioid receptor-mediated changes in neuronal metabolism that are exacerbated by secondary hypoxic insult. If recognized promptly, this syndrome can be treated with emergent neurosurgical intervention with good clinical outcomes. These cases also illustrate the unintended consequences and innocent victims of the spiraling prescription opioid epidemic, which will likely increase in prevalence. Recognition of this syndrome by clinicians is thus critical.

    Kelly, G N; Charles, D; Hemming, C R

    1983-01-01

    This report contains an assessment of the radiological impact on the Greater London population of postulated accidental releases from the Sizewell PWR. Three of the degraded core accident releases postulated by the CEGB are analysed. The consequences, conditional upon each release, are evaluated in terms of the health impact on the exposed population and the impact of countermeasures taken to limit the exposure. Consideration is given to the risk to the Greater London population as a whole and to individuals within it. The consequences are evaluated using the NRPB code MARC (Methodology for Assessing Radiological Consequences). The results presented in this report are all conditional upon the occurrence of each release. In assessing the significance of the results, due account must be taken of the frequency with which such releases may be predicted to occur.

    March 1, 1984, was the 30th anniversary of the Bravo thermonuclear test that resulted in the accidental exposure of the populations of Rongelap and Utirik atolls to radioactive fallout. The chronicling of the medical events resulting from that exposure is continued in this report, which covers the period from January 1983 through December 1984. An updated listing of all relevant publications from the Medical Department Brookhaven National Laboratory, is presented in the Reference Section. Thirty years of observation continue to show no detectable increase in mortality in the exposed population as a result of that exposure. The survival curves of the high-exposure Rongelap group, the low-exposure Utirik population, and an unexposed group of Rongelap people matched by age and sex to the exposed Rongelap group in 1957 continue to be similar. 89 refs., 2 figs., 6 tabs

    A computer program, SUBDOSA, was developed for calculating external γ and β doses to individuals from the accidental release of radionuclides to the atmosphere. Characteristics of SUBDOSA are: doses from both γ and β radiation are calculated as a function of depth in tissue, summed and reported as skin, eye, gonadal, and total body dose; doses are calculated for releases within each of several release time intervals and nuclide inventories and atmospheric dispersion conditions are considered for each time interval; radioactive decay is considered during the release and/or transit using a chain decay scheme with branching to account for transitions to and from isomeric states; the dose from gamma radiation is calculated using a numerical integration technique to account for the finite size of the plume; and the program computes and lists the normalized air concentrations at ground level as a function of distance from the point of release.

    1988-08-01

    Of the more than 450 underground nuclear explosives tests conducted at the Nevada Test Site from August 1963 (signing of the Limited Test Ban Treaty) through the end of 1986, only 23 accidentally released radioactivity that was detectable beyond the boundary of the NTS. Of these 23, 4 were detectable off the NTS only by aircraft while the remainder were detectable by ground monitoring instruments. Since the Baneberry venting of December 1970, only two tests released radioactivity that was detectable off the NTS, and this was a seepage of radioactive noble gases. None of these releases from underground tests designed for complete containment caused exposure of the population living in the area that exceeded standards recommended by national and international radiation protection agencies. This report summarizes the releases from each of the tests, describes the monitoring that was conducted, and lists the location of the maximum exposure

    In December 1973 a technician was accidentally irradiated when attempting to bring under control a sealed 60 Co source (110 TBq) which had been lodged in the head of a medical irradiation unit during a replacement operation. In the early period after the accident, severe skin changes on the left hand, epilation in a small area of the left temporal region and minor deviations in peripheral blood developed. In the following years, repeated surgery due to secondary skin defects of the left hand resulted in the loss of the fingers 2-5. Since 1975, changes in the lens of the left eye began to appear leading gradually to the deterioration of visual acuity. Later, opacities of the lens of the right eye were found. The patient's psychological and emotional attitude about the accident changed in the course of time. The factors influencing the psychic state of the patient are identified

  8. Children's Intrinsic Motivation to Provide Help Themselves After Accidentally Harming Others.

    2017-07-01

    Little is known about the flexibility of children's prosocial motivation. Here, 2- and 3-year-old children's (n = 128) internal arousal, as measured via changes in pupil dilation, was increased after they accidentally harmed a victim but were unable to repair the harm. If they were able to repair (or if they themselves did not cause the harm and the help was provided by someone else) their arousal subsided. This suggests that children are especially motivated to help those whom they have harmed, perhaps out of a sense of guilt and a desire to reconcile with them. Young children care not only about the well-being of others but also about the relationship they have with those who depend on their help. © 2016 The Authors.

  9. Parents accidentally substitute similar sounding sibling names more often than dissimilar names.

    Directory of Open Access Journals (Sweden)

    Zenzi M Griffin

    Full Text Available When parents select similar sounding names for their children, do they set themselves up for more speech errors in the future? Questionnaire data from 334 respondents suggest that they do. Respondents whose names shared initial or final sounds with a sibling's reported that their parents accidentally called them by the sibling's name more often than those without such name overlap. Having a sibling of the same gender, similar appearance, or similar age was also associated with more frequent name substitutions. Almost all other name substitutions by parents involved other family members and over 5% of respondents reported a parent substituting the name of a pet, which suggests a strong role for social and situational cues in retrieving personal names for direct address. To the extent that retrieval cues are shared with other people or animals, other names become available and may substitute for the intended name, particularly when names sound similar.

  10. Implications of the new ICRP recommendations for the management of post-accidental situations

    1992-01-01

    From an analysis of the new ICRP recommendations in relation with the management of post-accidental situations, there appears that no significant changes in comparison with the present situation will result. The consequences are rather an attempt to further clarify and justify the way in which the system of radiation protection applies to such situations, corresponding clearly to 'intervention situation', especially: - the use of the justification and optimization principles for the decision of implementing a protective measure. - the use of 'intervention levels' instead of individual 'dose limits'. In addition, and although there is no link at all between the dose limits applying in 'practices situations' and the intervention levels, the increase of risk factors could also result in a change of intervention levels.

    To discuss the possible etiopathogenetic mechanism of inner ear damage induced by the ingestion of potassium hydroxide (KOH). We report the case of a 37-year-old patient with sudden bilateral sensorineural hearing loss after accidental ingestion of a KOH solution. The first ear, nose and throat examination disclosed only mild edema of the upper airways. He was treated in the intensive care unit and prescribed high-dose steroids, proton pump inhibitors and sucralfate for 2 weeks. Unfortunately, there was no recovery of the hearing loss, and no audiogram changes were noticed after 12 months of follow-up. After exploring the possible etiopathogenetic mechanism involved, the authors believe that in this case, a transient severe hemodynamic imbalance can actually be considered to be the most reliable explanation for the inner ear damage and subsequent onset of permanent bilateral sensorineural hearing loss.

    The rapid assessment of the radiation dose after unexpected exposure is a task of accidental dosimetry. In case of a radiological accident glasses originating from mobile phone screens, placed usually near the human body, could be used as emergency thermoluminescent (TL) personal dosimeters. The time between irradiation and TL readout is crucial and therefore preparation of the mobile phone screens and their readout conditions should be optimized. The influence of the samples etching, bleaching and selection of the optical filters based on measurement of the emission spectrum of irradiated glass samples during heating for different types of mobile phones were the subjects of our investigation. Obtained results showed that glasses extracted from different brands of mobile phones have different dosimetric properties but all of them give a luminescent signal which can be used to calculate the dose.

    To describe the side effects and management after inadvertent injection of a dexamethasone implant (Ozurdex) into the crystalline lens. Two case reports. Two patients with macular edema due to unilateral retinal vein occlusion were scheduled for an intravitreal injection of Ozurdex. During the procedure, the implant was accidentally injected into the crystalline lens. Both patients developed cataracts during the course of several weeks and in both there was an intraocular pressure (IOP) increase, which required treatment with topical hypotensives. Macular edema improved only slightly. Cataract surgery with uneventful removal of the implant was performed 3 (case 1) and 6 months (case 2) after the injection. After inadvertent injection of Ozurdex into the crystalline lens, cataract surgery with removal of the implant should be performed as soon as possible in order to avoid IOP increase and so that the underlying condition may be treated adequately.

    Full Text Available After missing for seven days, a 34-year-old female was found with a rectal temperature of 19.8oC. Instead of attempting aggressive rewarming in the emergency department she was directly transferred to the operating room for extracorporeal rewarming. She received cardiopulmonary bypass (CPB for 66 minutes at an initial warming rate of 12oC/ hour and warmed to 36.2oC. Her postoperative course was complicated by sepsis, which eventually led to bilateral below-knee amputations after refusing antibiotics. She was discharged 22 days after admission, with full neurologic recovery. This remarkable case highlights the emerging role of CPB as the definitive therapy for severe accidental hypothermia.

    Highly toxic hydrogen selenide and hydrogen sulfide gases are used in the production of copper-indium-diselenide photovoltaic cells by reactive sputtering. In the event of an accident, these gases may be released to the atmosphere and pose hazards to public and occupational safety and health. This paper outlines an approach for designing systems for the control of these releases given the uncertainty in release conditions and lack of data on the chemical systems involved. Accidental releases of these gases in storage cabinets can be controlled by either a venturi and packed-bed scrubber and carbon adsorption bed, or containment scrubbing equipment followed by carbon adsorption. These systems can effectively reduce toxic gas emissions to levels needed to protect public health. The costs of these controls (˜0.012/Wp) are samll in comparison with current (˜6/Wp) and projected (˜I/Wp) production costs.

    This contribution is dedicated to the latest methodological developments implemented in the fast transient dynamics software EUROPLEXUS (EPX) to simulate the mechanical response of fully coupled fluid-structure systems to accidental situations to be considered at reactor scale, among which the Loss of Coolant Accident, the Core Disruptive Accident and the Hydrogen Explosion. Time integration is explicit and the search for reference solutions within the safety framework prevents any simplification and approximations in the coupled algorithm: for instance, all kinematic constraints are dealt with using Lagrange Multipliers, yielding a complex flow chart when non-permanent constraints such as unilateral contact or immersed fluid-structure boundaries are considered. The parallel acceleration of the solution process is then achieved through a hybrid approach, based on a weighted domain decomposition for distributed memory computing and the use of the KAAPI library for self-balanced shared memory processing inside sub-domains.

  17. The European Community dimension to the problem of accidental radioactive releases to the environment

    The European Community has to comply with the provisions of the Euratom Treaty, 1957. As well as providing the conditions necessary for the growth of nuclear industries it lays down the task to establish uniform Safety Standards to protect the health of workers and of the general public. This includes emergency planning in case of nuclear accidents. As a result the Community followed the guide, published in 1982 by the International Commission on Radiological Protection, on the radiological protection criteria for controlling doses to the public in the event of accidental releases of radioactive materials. However when the Chernobyl accident occured the Community and International arrangements proved to be inadequate to respond to the consequent widespread contamination over Europe. Measures have been taken since then to improve the preparedness of the Community. They include better exchange of information, control of contaminated foodstuffs and better information to the public.

    The consequences of an accidental beam loss in superconducting accelerators and colliders of the next generation range from the mundane to rather dramatic, i.e., from superconducting magnet quench, to overheating of critical components, to a total destruction of some units via explosion. Specific measures are required to minimize and eliminate such events as much as practical. In this paper we study such accidents taking the Superconducting Supercollider complex as an example. Particle tracking, beam loss and energy deposition calculations were done using the realistic machine simulation with the Monte-Carlo codes MARS 12 and STRUCT. Protective measures for minimizing the damaging effects of prefire and misfire of injection and extraction kicker magnets are proposed here

    A knowledge model uses different techniques of complex systems management. Progress realised in the computer representation of links between different documents allows us to design a software facilitating the comprehension of the model built. This model is a qualitative model of the operators' behaviour in nuclear power plant accidental control. This model concerned three topics closely linked together. The first gives a description of every physical phenomena implied the application of the State-oriented Approach (APE in French) procedures. It's referred as model of process. The second gives a description of every activities used by the operators' team to manage all thermohydraulic incidents and accidents. It's a functional model also referred as tasks model. The quality of the method, based on the Systems' Science, capitalized a know-how simply transferable to design a new software on industrial process to support the operators. (author)

    As one of the key safety issues of fusion reactors, tritium environmental impact of fusion accidents has attracted great attention. In this work, the dynamic tritium concentrations in the air and human body were evaluated on the time scale based on accidental release scenarios under the extreme environmental conditions. The radiation dose through various exposure pathways was assessed to find out the potential relationships among them. Based on this work, the limits of HT and HTO release amount for arbitrary accidents were proposed for the fusion reactor according to dose limit of ITER. The dynamic results aim to give practical guidance for establishment of fusion emergency standard and design of fusion tritium system. - Highlights: • Dynamic tritium concentration in the air and human body evaluated on the time scale. • Different intake forms and relevant radiation dose assessed to find out the potential relationships. • HT and HTO release amount limits for arbitrary accidents proposed for the fusion reactor according to dose limit
