    The Computed Tomography (CT) imaging diagnosis it is responsible for over 34% of the radiation dose given to society, only in Brazil there is around 3833 CT equipment. There are two dose index in CT, the CTDI{sub vol} and DLP that represents the Computed Tomography dose index and the product of the CTDI{sub vol} by the length of irradiation. This paper has as objective describe the values of CTDI{sub vol} e DLP for pediatric exams of chest and head. This is an exploratory study of bibliography revision on the PubMed data base using the index terms with the following crossing: Computed Tomography AND Reference Levels AND Dose. The search was limited by published studies on the last 5 years with patients among 0 and 15 years, in English or Portuguese. Besides that, were included references guides suggest by scientific and governmental organizations on the last 5 years. The data analysis was made using the four readings of Gil: exploratory, selective, analytic and interpretative. By the Exploratory Reading were located 23 articles. On the Selective Reading were excluded 4 articles and on the Analytic Reading 9 articles. The Interpretative Reading was made using 7 publications. Regarding the references guides were includes 3 guides. The Portaria MS453/98 was included for being the only national publication. All data were characterized between practical levels and reference levels. The conclusion is that there is no consensus between the reference levels for the selected articles, for pediatric exams. Besides that, the national legislation do not have reference levels for pediatric CT. (author)

    strategies or protocols to colonoscopy. The various diagnostic methods for the detection od CRC are explained. The fecal immunohistochemical tests (FIT) to detect blood in the stool have been more specific that guaiac fecal occult blood tests (gFOBT), because of they react only with human hemoglobin. Reasonable evidence has existed that the FIT has been superior than gFOBT with respect to acceptance of the population, the detection rate and positive predictive value of adenomas and CRC. Mortality by CRC has decreased with the screening of FIT screening. The double contrast barium enema has been a valid cost-effective technique in the programs of early detection and diagnostic of colonic pathologies [Spanish] Una revision de la evidencia disponible es realizada en torno a las indicaciones apropiadas y criterios de calidad en colonoscopia. Esta revision ha servido como instrumento a los programas de deteccion temprana, diagnostico y tratamiento de las enfermedades colonicas en las unidades de endoscopia y endoscopistas que han efectuado colonoscopia. El cancer colorrectal (CCR) ha sido una enfermedad prevenible basada en los efectos de factores de riesgo manipulables y tamizaje para la deteccion temprana del mismo. La historia familiar, edad avanzada, el sexo masculino, el numero de tamano de los adenomas, la presencia de un componente velloso, la displasia de alto grado y la localizacion proximal son asociados con un aumento significativo del riesgo para CCR. La indicacion inapropiada/innecesaria del procedimiento y la falta de uniformidad de criterios, ignorando las guias clinicas internacionales de indicacion de colonoscopia, ha causado un colapso de las unidades de endoscopia en el mundo en perjuicio de la calidad. Los indicadores de calidad aplicables son definidos localmente para establecer con base en la evidencia disponible, los requisitos minimos que deben cumplir las unidades de endoscopia y endoscopistas que han participado en los programas de cribado de CCR.

    Full Text Available A lo largo de 1999, se ha venido intensificando el debate sobre la seguridad de los alimentos modificados genéticamente, una importante y compleja área de investigación científica, la cual demanda unos estándares rigurosos. Diversos grupos, incluyendo asociaciones de consumidores y Organizaciones no Gubernamentales (ONGs han sugerido que todos los alimentos modificados genéticamente deberían ser sometidos a estudios a largo plazo con animales antes de su aprobación para el consumo humano. El principal objetivo de la presente revisión ha sido conocer cual es el estado actual de la cuestión en lo referente a los potenciales efectos adversos sobre la salud de los alimentos modificados genéticamente. Dos bases de datos, Medline y Toxline, así como una serie de direcciones de internet, han sido empleadas para la obtención de bibliografía. Aunque son numerosos los comentarios, noticias generales y cartas al Editor aparecidos en prestigiosas revistas, los artículos referentes a estudios experimentales sobre la seguridad de los alimentos modificados genéticamente son, sorprendentemente, muy escasos. Si se han obtenido resultados procedentes de la evaluación toxicológica de estos alimentos, no han sido publicados en revistas científicas y, por lo tanto, no han podido ser debidamente juzgados o contrastados.

Métodos: Estudo transversal e analítico, com 73 gestantes adolescentes de 10 a 19 anos, atendidas no Núcleo de Assistência ao Adolescente (NASA do Hospital Materno Infantil, em São Luís, Maranhão. Utilizou-se o Questionário de Frequência de Consumo Alimentar (QFCA, medidas antropométricas (peso, altura, índice de massa corporal - IMC - pré-gravídico e gravídico e questionário socioeconômico. As variáveis dependentes foram o consumo de frutas, verduras e legumes, e as independentes foram escolaridade, estado civil, raça, renda, situação demográfica, dados gestacionais e antropométricos. Resultados: Observou-se que 39,7% apresentaram IMC pré-gestacional de desnutrição, 50,7% de eutrofia, e menos de 10% sobrepeso ou obesidade. Para o IMC gestacional, os valores se alteraram, com 27,4% das gestantes desnutridas, 57,5% eutróficas e 15,1% com sobrepeso. Observou-se que os maiores percentuais de adequação para o consumo de frutas, verduras e legumes foram em adolescentes casadas ou em união estável (65,4%, que não trabalhavam (92,3% e com renda familiar menor que 1 salário mínimo (84,62%. Entretanto, a única associação positiva encontrada com o consumo de frutas, verduras e legumes foi o início do pré-natal. Conclusão: A maior parte das gestantes avaliadas apresentou-se eutrófica, apesar de cerca de um quarto apresentar baixo peso durante a gestação. Além disso, elas não consumiam uma dieta balanceada, com uma ingestão abaixo do recomendado de FVL. Entre os fatores relacionados a um melhor consumo de FVL destaca-se o início do acompanhamento pré-natal no primeiro trimestre.

    Full Text Available O látex está sendo considerado o alergênico do ano 2000, tendo em vista que inúmeros indivíduos, principalmente profissionais da área de saúde e pacientes submetidos a várias intervenções diagnósticas e terapêuticas, estão freqüentemente expostos aos alérgenos do látex, presentes em produtos de borracha natural. As manifestações clínicas conseqüentes às reações alérgicas de hipersensibilidade imediata vão desde rinite, urticária, conjuntivite, angioedema, asma, até anafilaxia. Estudos recentes estão demonstrando que pacientes alérgicos ao látex desenvolvem concomitantemente sensibilização a certos alimentos de origem vegetal, especialmente frutas como papaia, figo, banana, abacate, kiwi, pêssego, abacaxi, melão e castanha, acreditando-se numa provável ocorrência de reações cruzadas entre os alérgenos do látex e destas frutas. Faz-se, então, uma revisão sobre a alergia ao látex, em particular sobre os grupos de risco, incluindo a presença de reatividade cruzada entre o látex e as frutas.The latex is being considered the allergenic agent of the year 2000, taking into account that several individuals, mainly health care professionals, and patients who had undergone many diagnostic and therapeutic interventions, are frequently exposed to latex allergens, which are present in natural rubber latex products. The clinical manifestations, derived from allergic reactions of immediate hypersensitivity vary from since rhinitis, conjunctivitis, urticaria, angioedema, asthma, to anaphylaxis. Recent researches are demonstrating that patients allergic to latex develop concomitantly sensitization to certain vegetable foods, especially fruits like papaya, fig, banana, avocado, kiwi, peach, pineapple, melon and chestnut, and a probable occurrence of cross reaction between allergens of latex and of these fruits is believed.

    Full Text Available A definição de alimentos funcionais ainda é controversa na literatura, são definidos como aqueles que apresentam concentrações de um ou mais ingredientes modificados ou manipulados para melhorar sua contribuição para dieta saudável. Esses alimentos apresentam ainda nutrientes em quantidades apreciáveis, como é o caso das frutas e hortaliças que apresentam em sua composição compostos antioxidantes capazes de combater os radicais livres. Objetivou-se com essa revisão bibliográfica discutir os benefícios dos compostos com atividade antioxidantes presentes em frutas e hortaliças. Este estudo se utilizou da revisão de literatura para buscar evidencias sobre o tema abordado. Os carotenoides formam uma classe de pigmentos presentes nos vegetais, além das propriedades biológicas envolvendo sua atividade antioxidante, destacarmos a função antioxidante dos compostos fenólicos e das vitaminas A, C e E. As vitaminas são substâncias orgânicas presentes em muitos alimentos em pequenas quantidades e essenciais para o bom funcionamento de muitos processos fisiológicos do corpo humano. O aumento do consumo de frutas e hortaliças deve ser estimulado, pois diversos compostos presentes na célula vegetal como visto no presente trabalho, dentre eles a função antioxidante das vitaminas A, C e E, desempenham proteção e redução do risco de diversas doenças.Antioxidant capacity of fruits and vegetablesAbstract: The definition of a functional food is still controversial in literature, they are defined as those having concentrations of ingredients one or more modified or manipulated to enhance their contribution to healthy diet.

    Full Text Available En la presente revisión se presenta información sobre superficie, producción, y rendimiento de los frutales en Venezuela. Además se hacen consideraciones sobre los sistemas de producción, destacando limitaciones, avances y sugerencias. La fruticultura en Venezuela ocupa el 3er. lugar dentro del sector agrícola vegetal. Existen 167.691 Ha de frutales y una producción 2.232.088 TM por año. Se producen comercialmente una docena de rubros frutícolas, siendo los principales: plátano, banano, naranjo y piña. Las áreas de producción van desde zonas bajas y áridas, en donde se obtienen uvas y piñas; hasta zonas altas y húmedas donde se hallan duraznos y fresas. Ha habido reducción de la superficie plantada, con excepción de lechosa, piña y aguacate. El manejo hortícola de los huertos frutícolas es heterogéneo, ya que se observa desde bajo hasta alto nivel de tecnología. La incorrecta aplicación de las prácticas hortícolas origina baja productividad y calidad de fruta. La poscosecha podría mejorarse a través del desarrollo e implementación de normas de clasificación, empaque, embalaje, y cadena de frío. La exportación de frutas venezolanas se ha reducido en los últimos años y se concentra en mango, naranja y lima Tahití. Los principales destinos son Colombia, Europa, Norteamérica y las islas del Caribe. Sólo la naranja se procesa de manera importante en Venezuela. Las perspectivas para la fruticultura venezolana es continuar como una actividad dirigida al mercado interno, no se vislumbra una mayor participación del país en el mercado internacional.

    2012-06-01

    Full Text Available As tendências do mercado mundial de alimentos apontam para alto crescimento no consumo de produtos naturais, como as frutas e verduras. O mercado mundial de frutas frescas registrou, em 2005, cifra superior a US$ 31,5 bilhões e cresce US$ 1 bilhão ao ano, em média. Tal fato se reproduz no Brasil, onde se observa elevação do consumo de frutas. Em termos monetários, o valor bruto da produção de frutas no Brasil atingiu, em 2006, cerca de R$ 16,3 bilhões, 16,5% do valor da produção agrícola brasileira. O presente trabalho buscou analisar características econômicas da participação brasileira no comércio mundial de frutas, entre 1997 e 2008. Ademais, foi analisada a evolução da balança comercial das principais frutas brasileiras, discriminação das exportações em frescas ou processadas, representatividade do comércio externo no valor da produção nacional e participação da exportação de frutas selecionadas na exportação total do agronegócio. Foram utilizados dados da Pesquisa de Orçamento Familiar (POF do Instituto Brasileiro de Geografia e Estatística; o Sistema de Análise e Levantamento do Comércio Exterior - AliceWeb do Ministério do Desenvolvimento, Indústria e Comércio Exterior e o banco de dados do Ministério da Agricultura, Pecuária e Abastecimento. Após levantamento das frutas que seriam estudadas, constatou-se que o crescimento das exportações foi maior que o crescimento das importações brasileiras de 1997 a 2008. Isso contribuiu para que o seu saldo comercial aumentasse em 112% no período. As exportações de frutas frescas cresceram relativamente mais que as exportações de frutas processadas. Porém houve queda da participação das exportações de frutas nas exportações do agronegócio brasileiro, de 5,8%, em 1997, para 3,9%, em 2008.

    Full Text Available

    A vitamina C participa de inúmeras reações no organismo humano, sendo responsável, por exemplo, pela síntese e manutenção do colágeno e pela síntese de importantes neurotransmissores. O homem não sintetiza a vitamina C tornando necessária sua ingestão pela dieta alimentar. Frutas como acerola, cupuaçu, goiaba e laranja são importantes fontes de vitamina C na dieta. A produção de polpas e sucos vem sendo estimulada devido à sazonalidade da produção e à perecibilidade das frutas. Contudo, durante a produção de sucos de fruta e ao longo de sua vida-de-prateleira pode ocorrer degradação da vitamina C. Os principais fatores que influenciam na degradação da vitamina C dos sucos de fruta são o tipo de processamento, as condições de estocagem, o tipo de embalagem, a presença de oxigênio, de luz e de enzimas.

    Full Text Available Com o objetivo de determinar o efeito da densidade de plantio sobre o crescimento da planta, a produtividade e características químicas relacionadas à qualidade organoléptica das frutas da cultivar de morangueiro Camino Real em sistema hidropônico do tipo NFT, diferentes densidades de plantio foram avaliadas: 15,0; 12,5; 10,7 e 9,3 plantas m-2, correspondentes ao espaçamento entre plantas de 0,25; 0,30; 0,35 e 0,40 m, sendo fixado o espaçamento entre linhas de 0,18 m. O sistema NFT foi constituído por bancadas de telhas de fibrocimento de 1,10 x 2,44 m, considerando-se cada ondulação côncava da telha como um canal de cultivo. O transplante foi realizado em 26-04-2010, encerrando-se o experimento em 05-01-2011. Avaliaram-se a matéria fresca e seca de folhas, coroa, raízes e frutas, a área foliar, o número de frutas e o peso médio das frutas. Amostras das frutas foram analisadas em relação ao teor de sólidos solúveis totais (SST e à acidez total titulável (ATT. Com base nos resultados obtidos, conclui-se que o crescimento e a produtividade individual das plantas da cultivar de morangueiro Camino Real não são afetados pela elevação da densidade de plantio, no intervalo entre 9,3 e 15,0 plantas m-2. O crescimento e a produtividade por unidade de área, bem como a concentração de sólidos solúveis totais e a relação SST/ATT apresentam resposta linear ao incremento da densidade de plantio. Sugere-se a adoção da densidade de 12,5 plantas m-2, que proporcionaria rendimento mais elevado (2,79 kg m-2 de frutas com adequadas características organolépticas e redução no número de mudas necessárias, em relação à densidade de 15,0 plantas m-2. Existe a necessidade de desenvolver estudos adicionais com a cultivar Camino Real, a fim de promover adaptações no sistema e verificar a viabilidade econômica de seu cultivo em hidroponia.

    The paper explains the theoretical background and findings of an empirical study of revision policies, using Denmark as a case in point. After an overview of important definitions, types and parameters, the paper explains the methods and data gathered from a questionnaire survey and an interview...... survey. Results clearly show that most translation companies regard both unilingual and comparative revisions as essential components of professional quality assurance. Data indicate that revision is rarely fully comparative, as the preferred procedure seems to be a unilingual revision followed by a more...... or less comparative rereading. Though questionnaire data seem to indicate that translation companies use linguistic correctness and presentation as the only revision parameters, interview data reveal that textual and communicative aspects are also considered. Generally speaking, revision is not carried...

    Full Text Available En Argentina, la producción cítrica es muy importante. Para el control de enfermedades y plagas en las quintas y empaques son utilizados diferentes pesticidas. Los objetivos de este estudio fueron: optimizar diferentes metodologías analíticas para la determi- nación de residuos de pesticidas en fruta y aceite esencial, y determinar el efecto de la carga inicial sobre los aceites esenciales obtenidos durante el proceso industrial. La calibración se llevó a cabo con matriz adicionada debido al efecto matriz. Los mé- todos propuestos fueron selectivos, precisos, exactos y sensibles. La concentración de residuos encontrados en fruta fresca varió dependiendo del lote y pesticida. La persistencia en fruta postlavada, aceite pulido y descerado fue distinta para cada analito. Se observó una ligera reducción de los residuos en el aceite descerado debido probablemente a la partición de los mismos en la fase cerosa. Los resultados muestran que la carga inicial en la fruta es significante.

    Full Text Available As frutas nativas do cerrado têm despertado ultimamente interesse crescente, devido às suas propriedades nutricionais e funcionais aliadas ao potencial para agregar valor e conservar a biodiversidade deste bioma. Muitos compostos fenólicos apresentam capacidade antioxidante de neutralizar a atividade de radicais livres gerados no organismo, que estão associados a diversas doenças crônico-degenerativas. O objetivo deste trabalho foi avaliar a eficiência de três soluções extratoras (acetona a 70 %, etanol a 95 % e metanol a 99,8 % e determinar os teores de compostos fenólicos em 10 espécies de frutas nativas do cerrado, utilizando o método de Folin-Ciocalteou para compostos fenólicos totais e o método da vanilina para taninos condensados. A acetona a 70 % mostrou-se como o melhor solvente extrator de compostos fenólicos totais e taninos condensados em frutos de Pouteria gardneriana, Eugenia dysenterica, E. klostzchiana, E. punicifolia, Plinia edulis, Campomanesia sp., fenólicos totais de Brosimium gaudichaudii e taninos condensados de Jaracatia spinosa. O etanol a 95 % foi mais eficiente na extração de fenólicos totais de Jaracatia spinosa e taninos condensados de Brosimium gaudichaudii; o metanol a 99,8 % foi mais eficiente na extração de taninos condensados de Eugenia dysenterica. Os teores de compostos fenólicos totais variaram entre 90 e 327 mg de ácido gálico equivalente por 100g de polpa para as espécies E. dysenterica e E. punicifolia, respectivamente. Os teores de taninos condensados variaram entre 4 e 291 mg de catequina equivalente por 100 g de polpa para as espécies E. dysenterica e E. calcyna, respectivamente. As espécies de frutas do cerrado, avaliadas neste estudo, podem ser consideradas boas fontes de compostos fenólicos totais, sendo que a natureza específica dos diferentes tipos deve ser avaliada em estudos futuros.

    Full Text Available OBJETIVO: Estimar a disponibilidade de polifenóis totais em frutas e hortaliças consumidas no Brasil segundo macrorregião e identificar os principais alimentos-fonte que fazem parte do hábito alimentar nacional. MÉTODOS: O conteúdo de polifenóis foi determinado pelo método Folin-Ciocalteu e sua disponibilidade foi estimada com base na Pesquisa de Orçamentos Familiares 2002/2003. Foram escolhidos 12 alimentos de maior consumo, sendo seis "frutas tropicais" e seis "hortaliças folhosas e florais", "hortaliças frutosas" e "hortaliças tuberosas". A determinação de polifenóis foi realizada em três experimentos independentes, cada um em duplicata. A disponibilidade nacional de polifenóis foi estimada por grama de peso fresco de cada vegetal analisado. A ingestão diária per capita no Brasil e regiões foi calculada como sendo o aporte diário de polifenóis fornecido pelo consumo dos 12 alimentos analisados. RESULTADOS: O teor de polifenóis nos alimentos variou de 15,35 a 214,84mg EAG/100g peso fresco. A disponibilidade nacional, com base na quantidade, em kg, adquirida anualmente no Brasil foi de 48,3mg/dia, tendo a região Sudeste e a região Centro-Oeste os maiores e menores valores, respectivamente. A banana foi a principal fonte de polifenóis consumida no Brasil, variando conforme macrorregião. CONCLUSÕES: A estimativa de disponibilidade de polifenóis no Brasil encontrada foi semelhante à de outros países. Diferenças observadas entre as macrorregiões geográficas podem estar diretamente relacionadas às diferenças culturais de cada região. Apesar de não haver uma quantidade recomendada para o consumo de polifenóis, a adoção da recomendação diária de frutas e hortaliças representa um aumento de 16 vezes na disponibilidade nacional de polifenóis, demonstrando a relação entre o consumo destes grupos alimentares com a ingestão de compostos bioativos benéficos à saúde.

    Full Text Available Os sucos de frutas tropicais conquistam cada vez mais o mercado consumidor, sendo o Brasil um dos principais produtores. Existe grande diversidade de produtos derivados de frutos e constante inserção de novos produtos no mercado de consumo, os quais, na maioria das vezes, ainda não foram devidamente pesquisados com respeito às suas propriedades e atividades benéficas à saúde. Neste trabalho, objetiva-se determinar algumas propriedades de frutos tropicais silvestres in natura e polpas de frutos comercializados congelados. Para determinar a atividade antioxidante, utilizou-se o método do radical 2,2-difeniL-1-picrilhidrazilo (DPPH.; para determinar os polifenóis totais, o método de Folin-Ciocalteu e, para as antocianinas, o método da diferença de pH. As polpas de frutas analisadas foram de amora, uva, açaí, goiaba, morango, acerola, abacaxi, manga, graviola, cupuaçu e maracujá; e os frutos silvestres, jambolão e baguaçu. Representada em TEAC (atividade antioxidante equivalente a Trolox, a atividade antioxidante global das polpas oscila entre mínimos e máximos 0,5 e 53,2mimol g-1, enquanto que, representada em VCEAC (atividade antioxidante equivalente a vitamina C, entre mínimos e máximos de 64,8 e 1198,9mg100g-1.

    Full Text Available A alimentação saudável e diversificada é essencial para a manutenção da saúde física e mental, e apesar de o perfil alimentar atual valorizar a praticidade do comer, nota-se que a população está consumindo, de forma crescente, frutas, tanto na forma in natura como na forma de sucos. No entanto, o consumo de certas frutas in natura ocorre acompanhado da ingestão de suas sementes, cascas ou mesmo outras partes, podendo existir fatores antinutricionais, moléculas e/ou compostos que podem interferir na biodisponibilidade e/ou digestibilidade de nutrientes, tais como os inibidores de tripsina. Tais inibidores podem prejudicar o aproveitamento de proteínas presentes nos alimentos, porém estudos recentes vêm sendo divulgados, demonstrando também os efeitos benéficos dos mesmos. Este estudo teve como objetivo avaliar inibidores de tripsina nos extratos aquosos das frutas: goiaba (Psidium guajava L, das variedades Kumagai (branca e Paluma (vermelha; maracujá-amarelo (Passiflora edulis f. e melancia (Citrullus vulgaris Schrad. Para tal, foi realizada a detecção da presença da atividade antitríptica e a dosagem de proteínas solúveis. Em todos os extratos analisados, foi detectada atividade inibitória de tripsina, bem como de proteínas solúveis. Assim, a inibição pode ser explicada pela presença de inibidores proteicos, pois, nos extratos de sementes, em SDS-PAGE, foi possível visualizar um largo espectro de bandas proteicas. Vale ressaltar que, no estudo, as bandas proteicas que coincidem com as massas moleculares dos inibidores de tripsina não apareceram de forma majoritária, demonstrando que os extratos de sementes, provavelmente, possuem inibidor proteico, no entanto em pouca quantidade, justificando a baixa atividade antitríptica (1,36 a 15,15 UI / mg de peso seco, também apresentada pelos extratos de polpa. Portanto, tendo em vista o consumo recomendado das frutas, incluindo goiaba, maracujá e melancia

El objetivo de este trabajo fue producir extractos a partir de las semillas de cinco frutas tropicales: mango (Mangifera indica, papaya (Carica papaya, guayaba (Psidium guajava, parchita (Passiflora edulis y melón (Cucumis melo, y medir su efecto sobre el crecimiento de las bacterias Staphylococcus aureus ATCC 25923 y Escherichia coli ATCC 25922. La extracción se hizo por maceración a temperatura ambiental usando etanol al 90 %. Se tomaron 100 μL de los extractos y se adicionaron al medio de cultivo. Las bacterias fueron incubadas por 6 horas y su crecimiento se midió por turbidimetría a 600 nm, cada 30 minutos. Se encontró que las bacterias crecidas en presencia del extracto de parchita, exhibieron los menores valores de absorbancia, indicativo del potencial inhibitorio. Este efecto fue confirmado mediante contajes en placas y el método de difusión en agar, donde las concentraciones de 11,7 y 9,4 mg/mL fueron las que presentaron mejor efecto sobre S. aureus.

    Resumen

    Los bulímicos son adictos a los alimentos por dos mecanismos posibles: uno, que perciben en forma desmedida las señales subliminales multisensoriales enviadas por los alimentos (el color rojo de la fruta se percibe con más intensidad, por ejemplo. El segundo puede radicar en que los bulímicos sufren de untrastorno en la liberación y/o señalización cerebral de las hormonas de la saciedad alimenticia provenientes del tracto gastrointestinal y del tejido adiposo como la GH-RELINA y la LEPTINA. Este artículo también resume las alteraciones endocrinas en la bulimia, además de las características de los pacientes con trastornos alimenticios como la bulimia nerviosa, la anorexia nerviosa y la enfermedad de las “comilonas compulsivas”.

    Palabras Clave: Trastornos de la alimentación, saciedad, neuropéptidos/apetito, señalizaciones visuales y aromáticas

    Abstract

    Bulimic patients are food-addicts, through two posible mechanisms. One, these persons magnify multisensensorial subliminal signals, sent by foods (i.e., red color of a fruit is perceived with greater intensity. Two, bulimics have a disordered release and/or signaling of brain-gut hormones and adipose-tissue hormones participating in saciety, such as Gh-relin and leptin. This paper includes brief remarks on endocrine dysregulation seen in” bulimia nervosa”. Also, it presents features of eating-disorder patients, such as those suffering from bulimia nervosa, anorexia nervosa y “binge-eating” disorder.

The pollen grains of six species of Chamaecrista [C. cathartica (Mart.) H.S. Irwin & Barneby, C. debilis Vogel, C. flexuosa (L.) Greene, C. hedysaroides (Vogel) H.S. Irwin & Barneby, C. glandulosa (L.) Greene, and C. papillata H.S. Irwin & Barneby] have a similar morphology, characterized by three long colporated apertures with a central constriction. The species share specific morphological features regarding pollen size, endoaperture type (circular, lalongate or lolongate) and SEM ornamentation patterns of the exine (rugulate with perforations or perforate). Andira fraxinifolia Benth., Dalbergia miscolobium Benth, Galactia martii DC, Periandra mediterranea (Vell.) Taub., Senna rugosa (G.Don) H.S. Irwin & Barneby and Zornia diphylla (L.) Pers showed different pollen types in small to large size; oblate spheroidal to prolate form; colpus or colporus apertures; circular, lalongate or lolongate endoapertures and distinctive SEM ornamentation patterns of the exine (perforate, microreticulate, reticulate or rugulate with perforations). Only Stryphnodendron adstringens (Mart.) Coville presents polyads. The pollen morphology variation of these species allowed the Fabaceae family to be characterized as eurypalynous in the SPA Pau-de-Fruta.

We used the following indicators: daily fruit intake, daily vegetable intake, and daily consumption of five or more servings of fruits and vegetables per day. Only 41.0% of adults reported daily fruit intake, while 30.0% reported daily vegetable intake. Fruit and vegetable intake was more common in urban as compared to rural areas and increased in both genders with age, schooling, and number of household goods. We conclude that initiatives to promote fruit and vegetable consumption are necessary for the country as a whole, but special attention should be given to younger individuals, males, rural communities, and groups with less schooling and lower income.O presente estudo estimou a freqüência e a distribuição do consumo de frutas e hortaliças e analisou a influência de variáveis demográficas e sócio-econômicas na determinação do padrão de consumo desses alimentos na população adulta do Brasil. Os indicadores do consumo alimentar foram: consumo diário de frutas, de hortaliças, consumo diário de frutas e hortaliças e consumo diário de cinco ou mais porções de frutas e hortaliças. Menos da metade (41,0% dos indivíduos adultos refere o consumo diário de frutas enquanto menos de um terço (30,0% refere o consumo diário de hortaliças. O consumo de frutas e hortaliças é maior nas áreas urbanas do que nas áreas rurais e aumenta com a idade e escolaridade dos indivíduos, e com o número de bens no domicílio, em ambos os sexos. Concluímos que iniciativas de promoção do consumo de frutas e hortaliças devem atender a população como um todo, mas que especial atenção deve ser dada a indivíduos jovens, ao sexo masculino, a áreas rurais e aos estratos populacionais com insuficiente escolaridade e baixa renda.

    Full Text Available O Brasil é o terceiro maior produtor de frutas, participando com 6% da produção mundial. Devido a maior preocupação e conscientização dos consumidores, atualmente, há grande procura por alimentos seguros e saudáveis, principalmente os consumidos in natura, que sejam produzidos respeitando o meio ambiente e sejam socialmente responsáveis. Para atender às exigências de mercado, normas internacionais de sistemas de gestão foram criadas pela necessidade de padronização de conceitos da qualidade a fim de proporcionar igual competitividade a qualquer organização, independentemente de sua dimensão e ramo de atuação, em qualquer país. Na área agrícola, normas de certificação também foram desenvolvidas e adaptadas pelo governo brasileiro para garantir a participação do Brasil no mercado externo, não sofrer restrição pelas barreiras não tarifárias além de produzir alimentos seguros e de qualidade. Nesse contexto, o objetivo deste trabalho é reunir elementos do sistema integrado de gestão, abrangendo as normas ISO 9001 e ISO 14001, gestão da qualidade e meio ambiente respectivamente, e relacioná-las com a produção e processamento pós-colheita de frutas como garantia de alimento seguro e de qualidade, a partir de certificações agrícolas como Boas Práticas de Fabricação (BPF, Análise de Perigos e Pontos Críticos de Controle (APPCC e Produção Integrada de Frutas (PIF, possibilitando apontar as vantagens de implantação e otimização de recursos e tempo de implementação de ações. Os princípios do sistema de gestão formam a base para a melhoria contínua do desempenho, focada nos objetivos do sistema e na identificação de seus componentes. Os sistemas de certificação da produção agrícola, se aliados a um sistema de gestão, podem apresentar maior eficácia e fluidez nos seus processos de produção.

    2013-01-01

    Full Text Available El patrón de cultivos de México ha evolucionado por las características propias de la actividad y las condiciones climatológicas que determinan en gran medida los volúmenes anuales de producción, afectados directamente por las variaciones en la superficie sembrada y cosechada y los rendimientos unitarios. Las tendencias en los hábitos de consumo y en los precios de los productos también son factores determinantes en la decisión de los agricultores sobre qué cultivos sembrar o plantar. La producción agrícola responde a la demanda derivada de la apertura comercial del país, acentuada con la firma del Tratado de Libre Comercio de América del Norte (TLCAN en 1994. El objetivo principal de esta investigación fue cuantificar los factores explicativos del crecimiento de la producción de frutas y hortalizas en México durante el periodo 1994 a 2009, a través de los efectos de la superficie, rendimiento, estructura de usos del suelo y su efecto combinado. Se utilizó la metodología de FAO (Gómez, 1994. El aumento de la superficie explica el 100 % del crecimiento de la producción de frutas, y el rendimiento explica 72.6 % del crecimiento en la producción de hortalizas. México es el principal proveedor de estos productos para Estados Unidos y el valor de las exportaciones hortofrutícolas ha crecido a tasas importantes, aunque ha perdido participación relativa en ese mercado.

    Full Text Available As propriedades termofísicas de alimentos, necessárias nas simulações e cálculos do processo de congelamento, incluem principalmente a densidade, condutividade térmica e calor específico. Neste trabalho, as difusividades e condutividades térmicas da solução, usadas como modelo para o congelamento de polpas de frutas, foram medidas pelo método da sonda com aquecimento. Os experimentos foram conduzidos na faixa de -25 a 0masculineC com modelos alimentícios constituídos de 0,5% de K- carrageenan + 10% de sacarose (massa/volume de água. Modelos estruturais foram usados para as avaliações da condução de calor, combinada com a fração de gelo predita para as amostras a partir dos modelos de Heldman e foram comparados com os valores das condutividades térmicas efetivas medidas. Os modelos estruturais empregados foram: em série, paralelo e Maxwell-Eucken, com o gelo considerado como a fase dispersa. Em todos os ensaios, o modelo de Maxwell-Eucken apresentou os melhores resultados (erro máximo de 6,13% quando comparado com os valores experimentais medidos e foi escolhido para a predição da condutividade térmica efetiva de soluções-modelo de polpas de frutas congeladas. Os valores calculados da condutividade térmica foram ajustados em termos de funções polinomiais, divididas em quatro faixas de temperatura e podem ser usadas na resolução dos problemas de transferência de calor, nos processos de congelamento.

    Full Text Available I libri di testo adottati nelle scuole contengono parole sconosciute e costruzioni sintattiche e testuali complesse che rappresentano dei veri e propri “muri linguistici” per gli alunni stranieri che non possiedono una buona conoscenza della lingua italiana. Ciò facilmente determina un divario di competenze tra l’apprendente straniero e i suoi compagni e ritardi scolastici molto spesso incolmabili con conseguente perdita di motivazione e di autostima, senso di frustrazione e isolamento che a volte sfocia in un disagio psico-sociale. Tra gli strumenti adottati dalla scuola italiana per far fronte a questo problema vi sono i testi disciplinari ad alta comprensibilità che, pur mantenendo la maggior parte delle informazioni, le veicolano in una forma più semplice dal punto di vista linguistico. L’articolo fornisce una bibliografia di manuali ad alta comprensibilità il più possibile aggiornata suddivisa per ordine e grado di scuola e per materia scolastica, con l’intento di fornire agli insegnanti un aiuto nella scelta e nel reperimento dei testi.     Language for study:  a bibliography   Textbooks used in schools contain unknown words and complex sentence constructions that create real “linguistic barriers” for foreign students who do not know Italian well.  This creates an abyss between the competence of the foreign learner and his or her classmates and unsuccessful school performance which is often not made up for and leads to a loss of self-esteem, frustration, isolation, and ultimately to psycho-social malaise.  Among the tools utilized in the Italian school system to address this problem are highly comprehensible textbooks which, while containing most of the information, express the content in simpler language.  This article offers an up-dated bibliography of textbooks which are easily understandable, divided according to order and grade of school, for teachers to use in choosing the textbooks for their classes.

    Full Text Available OBJETIVO: Estimar a disponibilidade de polifenóis totais em frutas e hortaliças consumidas no Brasil segundo macrorregião e identificar os principais alimentos-fonte que fazem parte do hábito alimentar nacional. MÉTODOS: O conteúdo de polifenóis foi determinado pelo método Folin-Ciocalteu e sua disponibilidade foi estimada com base na Pesquisa de Orçamentos Familiares 2002/2003. Foram escolhidos 12 alimentos de maior consumo, sendo seis "frutas tropicais" e seis "hortaliças folhosas e florais", "hortaliças frutosas" e "hortaliças tuberosas". A determinação de polifenóis foi realizada em três experimentos independentes, cada um em duplicata. A disponibilidade nacional de polifenóis foi estimada por grama de peso fresco de cada vegetal analisado. A ingestão diária per capita no Brasil e regiões foi calculada como sendo o aporte diário de polifenóis fornecido pelo consumo dos 12 alimentos analisados. RESULTADOS: O teor de polifenóis nos alimentos variou de 15,35 a 214,84mg EAG/100g peso fresco. A disponibilidade nacional, com base na quantidade, em kg, adquirida anualmente no Brasil foi de 48,3mg/dia, tendo a região Sudeste e a região Centro-Oeste os maiores e menores valores, respectivamente. A banana foi a principal fonte de polifenóis consumida no Brasil, variando conforme macrorregião. CONCLUSÕES: A estimativa de disponibilidade de polifenóis no Brasil encontrada foi semelhante à de outros países. Diferenças observadas entre as macrorregiões geográficas podem estar diretamente relacionadas às diferenças culturais de cada região. Apesar de não haver uma quantidade recomendada para o consumo de polifenóis, a adoção da recomendação diária de frutas e hortaliças representa um aumento de 16 vezes na disponibilidade nacional de polifenóis, demonstrando a relação entre o consumo destes grupos alimentares com a ingestão de compostos bioativos benéficos à saúde.OBJETIVO: Estimar la disponibilidad de

    Full Text Available Nos últimos anos, tem-se observado aumento na produção de uvas destinadas à elaboração de vinhos na região do Circuito das Frutas, Estado de São Paulo, promovido principalmente pelo turismo rural. O objetivo deste trabalho foi caracterizar o potencial climático dessa região para produção de uvas para vinho, utilizando o Sistema de Classificação Climática Multicritérios Geovitícola, baseado nos índices biometeorológicos: heliotérmico, de frio noturno e de seca, considerando as safras de verão e de inverno. Para a safra de verão, foram identificadas áreas com clima quente, úmidas e com noites quentes, situadas na região oeste do Circuito das Frutas; na região centro-leste, as noites foram caracterizadas como temperadas e, nas áreas de altitudes mais elevadas, o clima encontrado foi o temperado quente, sem período seco e com noites temperadas. Para a safra de inverno, os valores de umidade mantiveram-se elevados, com as classes climáticas variando entre quente, temperado quente e temperado, com noites muito frias. O Circuito das Frutas apresentou características que podem favorecer a obtenção de uvas para vinhos brancos e espumantes.

    Full Text Available El objetivo de este estudio fue analizar el efecto de la información nutricional sobre el consumo de frutas y verduras. Participaron 25 niños entre los 3 y 5 años, expuestos a alimentos con alto y bajo valor nutricional. Los niños fueron divididos en 2 grupos (piloto y experimental y expuestos a 4 fases. El grupo experimental recibió información sobre hábitos alimenticios, valor nutricional de los alimentos y beneficios del consumo de frutas y verduras. Los resultados mostraron que la información nutricional modificó la conducta alimentaria, ya que el consumo de alimentos poco nutritivos disminuyó. Sin embargo, el consumo de frutas y verduras no se incrementó. Los datos sugieren que la información nutricional influye en la adquisición de conductas alimentarias en niños preescolares, siempre y cuando incluya una duración y frecuencia adecuadas y sea reforzada en casa a través del modelamiento de los familiares.

    Full Text Available OBJETIVO: Analisar a influência da renda familiar e do preço de alimentos sobre a participação de frutas e hortaliças dentre os alimentos adquiridos pelas famílias brasileiras. MÉTODOS: Foram utilizados dados da Pesquisa de Orçamentos Familiares realizada pelo Instituto Brasileiro de Geografia e Estatística, com amostra probabilística de 48.470 domicílios brasileiros entre 2002 e 2003. A participação de frutas e hortaliças no total de aquisições de alimentos foi expressa como percentual do total de calorias adquiridas e como calorias provenientes desses alimentos ajustadas para o total de calorias adquirido. Empregaram-se técnicas de análise de regressão múltipla para estimação de coeficientes de elasticidade, controlando-se variáveis sociodemográficas e preço dos demais alimentos. RESULTADOS: Observou-se aumento da participação de frutas e hortaliças no total de aquisições de alimentos com a diminuição de seu próprio preço ou com o aumento da renda. A diminuição do preço de frutas e hortaliças em 1% aumentaria sua participação em 0,79% do total calórico; o aumento de 1% na renda familiar aumentaria essa participação no total calórico em 0,27%. O efeito da renda tendeu a ser menor nos estratos de maior renda. CONCLUSÕES: A redução do preço de frutas e hortaliças, tanto pelo apoio à cadeia de produção dos alimentos quanto por medidas fiscais, é um promissor instrumento de política pública capaz de aumentar a participação desses alimentos na dieta brasileira.

Objetivou-se, neste estudo, avaliar in vitro a capacidade antioxidante de um grupo de frutas e hortaliças, cruas e cozidas, através da diminuição da peroxidação lipídica, induzida por ferro em fígado de ratos. Foram utilizados fígados de ratos homogeneizados, que foram submetidos à oxidação pelo ferro. As frutas e hortaliças foram utilizadas como antioxidantes, a fim de combater o estresse oxidativo induzido pelo ferro. O método utilizado neste trabalho foi a Reação ao Ácido Tiobarbitúrico (TBARS, tendo como marcador para avaliar o estresse oxidativo o Malonaldeído (MDA. De acordo com os resultados obtidos, observou-se que houve uma diminuição significativa do estresse oxidativo no grupo das frutas e das hortaliças cruas e cozidas com ferro, quando o fígado foi submetido à oxidação deste micronutriente. No grupo das frutas e das hortaliças cruas e cozidas sem ferro, ocorreu redução significativa do estresse oxidativo, apenas em determinadas frutas e hortaliças. O consumo de uma dieta rica em frutas e hortaliças contribui com a defesa antioxidante do organismo, inibindo danos oxidativos em macromoléculas in vitro.The protector effect of fruits and vegetables has been attributed to the presence of antioxidant compounds.

    Full Text Available In the region of the Serra do Espinhaço Meridional, peat bog is formed in hydromorphic environments developed in sunken areas on the plain surfaces with vegetation adapted to hydromorphic conditions, favoring the accumulation and preservation of organic matter. This pedoenvironment is developed on the regionally predominant quartzite rocks. Peat bog in the Environmental Protection Area - APA Pau-de-Fruta, located in the watershed of Córrego das Pedras, Diamantina,Brazil, was mapped and three representative profiles were morphologically characterized and sampled for physical, chemical and microbiological analyses. The organic matter was fractionated into fulvic acid (FA, humic acids (HA and humin (H. Two profiles were sampled to determine the radiocarbon age and δ13C. The structural organization of the three profiles is homogeneous. The first two layers consist of fibric, the two subsequent of hemic and the four deepest of sapric peat, showing that organic matter decomposition advances with depth and that the influence of mineral materials in deeper layers is greater. Physical properties were homogeneous in the profiles, but varied in the sampled layers. Chemical properties were similar in the layers, but the Ca content, sum of bases and base saturation differed between profiles. Contents of H predominated in the more soluble organic matter fractions and were accumulated at a higher rate in the surface and deeper layers, while HA levels were higher in the intermediate and FA in the deeper layers. Microbial activity did not vary among profiles and was highest in the surface layers, decreasing with depth. From the results of radiocarbon dating and isotope analysis, it was inferred that bog formation began about 20 thousand years ago and that the vegetation of the area had not changed significantly since then.

    Full Text Available OBJETIVO: O objetivo do estudo foi investigar aspectos subjetivos do consumo de frutas, verduras e legumes entre agricultores. MÉTODOS: Trata-se de um estudo qualitativo sobre o universo simbólico do consumo de frutas, verduras e legumes entre fruticultores da zona rural, do município de Valinhos, estado de São Paulo, Brasil. Foram empregadas técnicas de observação participante e entrevista não estruturada focalizada. Para tratamento de dados foi utilizada a teoria das representações sociais de Moscovici. RESULTADOS: A representação central das falas analisadas é: fruta não é comida, é trabalho, a qual tem função estruturante de outras representações relativas a fruta: 1 não tem função de alimentar; 2 seu consumo não é essencial; 3 garante a sobrevivência do trabalho familiar no campo, representando o sustento familiar. Apesar de cultivadas e consumidas rotineiramente, são consideradas comida somente quando são compradas. Verduras e legumes são classificados como alimentos de importância secundária. Conceitos de alimentação saudável expressos pelo grupo contemplam elementos que vão além do valor nutricional dos alimentos, incluindo: prazer, comensalidade, valores sócio-culturais, memória familiar e celebrações. CONCLUSÃO: O consumo de frutas relaciona-se mais à esfera do trabalho na lavoura do que a elementos que a aproximem ao conceito de comida. As representações sociais relativas a Frutas Verduras e Legumes contribuem com a formulação de conceitos subjetivos de alimentação saudável e estruturam as práticas alimentares dos agricultores.OBJECTIVE: The objective of this study was to investigate subjective aspects in the consumption of fruits and vegetables by fruit growers.

    Full Text Available Quality control of fruits to satisfy increasingly competitive food markets requires the implementation of automatic servovisual systems in fruit processing operations to cope with market challenges. A new and fast method for identifying and classifying moving fruits by processing single color images from a static camera in real time was developed and tested. Two algorithms were combined to classify and track moving fruits on image plane using representative color features. The method allows classifying the fruit by color segmentation and estimating its position on the image plane, which provides a reliable algorithm to be implemented in robotic manipulation of fruits. To evaluate the methodology an experimental real time system simulating a conveyor belt and real fruit was used. Testing of the system indicates that with natural lighting conditions and proper calibration of the system a minimum error of 2% in classification of fruits is feasible. The methodology allows for very simple implementation, and although operational results are promising, even higher accuracy may be possible if structured illumination is used.El control de calidad en frutas y hortalizas para satisfacer mercados cada vez mas exigentes, requiere la implementación de sistemas automáticos servo visuales en operaciones de de procesamiento de frutas para responder a estos desafíos de mercado.

    Full Text Available Atualmente a procura por produtos mais saudáveis e inovadores, que sejam seguros e de prática utilização tem se intensificado. Seguindo esta tendência cresce o consumo de produtos diet e light. A substituição do açúcar por edulcorante é percebida na indústria que cada vez mais está lança no mercado produtos que possam atender às expectativas do consumidor. Neste contexto, esta prospecção buscou identificar através do levantamento de patentes publicadas ou concedidas, no que diz respeito à métodos,  equipamentos e produtos dietéticos ou de baixa calorias e suas aplicações industriais no  período de 1976 a 2013. A pesquisa foi realizada a partir de palavras-chave do tema e com códigos da classificação internacional de patentes na base de dados do Espacenet e INPI. O primeiro documento de patente identificado foi de 1976, sendo uma bebida a base de cola e frutas utilizando sacarose e maltitol como edulcorantes. O Brasil possui 17 patentes relacionadas a alimentos para fins dietéticos estando relacionados com a indústria de alimentos e farmacêutica, e à alimentos para indústria veterinária. Os principais detentores desta tecnologia são os países Asiáticos, liderados pela China que se destaca no número patentes depositadas relacionadas ao assunto. Apesar da crescente expansão deste mercado, é preciso discutir o processo de regulamentação dos produtos, estabelecer bases tecnológicas e científicas para o seu melhor desenvolvimento e viabilizar uma produção com alimentos que além de satisfazerem às necessidades nutricionais básicas desempenhavam efeitos fisiológicos benéficos.

    Full Text Available OBJETIVO: Avaliar o consumo de frutas e hortaliças por adultos e identificar variáveis sociodemográficas e de estilo de vida associadas ao consumo desses alimentos. MÉTODOS: Estudo transversal, de base populacional, realizado na área urbana de Ribeirão Preto, SP, em 2006, com amostra selecionada por conglomerados, em três estágios, tendo como unidade primária o setor censitário. A amostra foi composta por 930 participantes com 30 anos e mais; na análise de dados levou-se em consideração o efeito de desenho. O consumo de frutas e hortaliças baseou-se em questionário de freqüência semiquantitativo, utilizando-se como indicadores os escores médios de freqüência de consumo de frutas e hortaliças, consumo diário e consumo mínimo desses alimentos. As variáveis independentes analisadas foram: faixa etária, estado marital, escolaridade, renda familiar per capita, estado nutricional, tabagismo e atividade física. Médias dos escores de freqüência de consumo foram estimadas por pontos e por intervalos com 95% de confiança. Para o estudo de associação, razões de prevalências foram estimadas por pontos e por intervalos com 95% de confiança, utilizando-se regressão de Poisson. Testes de tendência linear foram aplicados, adotando-se nível de significância de 5%. RESULTADOS: Apenas 24% dos homens e 38% das mulheres atenderam à recomendação mínima do consumo de frutas e hortaliças; observou-se associação positiva com a idade e renda per capita. Mulheres com maior escolaridade e homens que viviam com a companheira consumiam mais frutas e hortaliças que os demais. Atividade física, tabagismo e estado nutricional não apresentaram associação com o consumo mínimo recomendado de frutas e hortaliças. CONCLUSÕES: Fatores socioeconômicos têm importante influência sobre o consumo de frutas e hortaliças e, por serem passíveis de intervenção, podem contribuir para a adoção de hábitos alimentares saud

    The use of acetabular cup revision arthroplasty is on the rise as demands for total hip arthroplasty, improved life expectancies, and the need for individual activity increase. For an acetabular cup revision to be successful, the cup should gain stable fixation within the remaining supportive bone of the acetabulum. Since the patient's remaining supportive acetabular bone stock plays an important role in the success of revision, accurate classification of the degree of acetabular bone defect is necessary. The Paprosky classification system is most commonly used when determining the location and degree of acetabular bone loss. Common treatment options include: acetabular liner exchange, high hip center, oblong cup, trabecular metal cup with augment, bipolar cup, bulk structural graft, cemented cup, uncemented cup including jumbo cup, acetabular reinforcement device (cage), trabecular metal cup cage. The optimal treatment option is dependent upon the degree of the discontinuity, the amount of available bone stock and the likelihood of achieving stable fixation upon supportive host bone. To achieve successful acetabular cup revision, accurate evaluation of bone defect preoperatively and intraoperatively, proper choice of method of acetabular revision according to the evaluation of acetabular bone deficiency, proper technique to get primary stability of implant such as precise grafting technique, and stable fixation of implant are mandatory.

    Full Text Available A obesidade tem se tornado um problema global de saúde pública devido ao fato de haver uma clara evidência entre obesidade e diversas patologias. Novos enfoques para o tratamento da obesidade envolvem a inibição da absorção de triglicerídeos através da inibição da lipase pancreática. Os produtos naturais merecem destaque como inibidores da enzima lipase, principalmente aqueles encontrados em frutas comestíveis. O objetivo deste trabalho foi avaliar tratamentos contra a obesidade, com ênfase no uso de extratos de resíduos de frutas e seus metabólitos secundários para inibição de enzimas relacionadas à absorção de nutrientes pelo corpo. Foi utilizado o Espacenet, pois este banco de dados engloba patentes nacionais e internacionais depositadas e concedidas em mais de 90 países, incluindo o Brasil. No Espacenet foram realizadas buscas em relação a tratamentos da obesidade com ênfase nos inibidores enzimáticos utilizando resíduos de frutas. A pesquisa de patentes demostrou que de 1996 a 2013 houve um aumento considerável no depósito de patentes envolvendo tratamentos antiobesidade. As áreas de maior relevância para proteção patentária foram aplicações para fins medicinais, terapêuticos e farmacêuticos, somando 91 patentes, sendo A61K a classificação internacional de patente mais recorrente.  Os códigos CO7D e A23L também aparecem referindo-se a compostos químicos e constituintes de alimentos usados em tratamentos físicos. Sendo que estudos e pesquisas nesse tema têm tido muitos avanços e existe um grande potencial no Brasil para essas pesquisas devido à grande diversidade vegetal.

    Full Text Available Avaliou-se os efeitos do processo utilizado na obtenção de polpa de frutas congelada sobre o teor de fibras alimentares, empregando-se acerola, caju, goiaba, graviola, manga, pinha, pitanga, sapoti e uva no estágio maduro. Demonstrou-se que o processo tecnológico empregado reduziu significativamente o percentual de fibras alimentares das frutas, determinadas por método gravimétrico não enzimático, principalmente da goiaba, seguida da uva, graviola, sapoti, caju, pinha e acerola; com exceção da manga e pitanga, as demais polpas congeladas não substituem, em termos quantitativos, a fibra alimentar dos frutos in natura na dieta de indivíduos sadios. Considerando que essas perdas são variáveis face às características dos frutos processados, a inclusão de polpas congeladas na dieta em substituição às frutas dependerá de estudos qualitativos que permitam esclarecer os constituintes da referida fração.The effects of the process utilized to obtain frozen fruit pulp on the quality of dietary fibers were evaluated, using ripe samples of acerola, cashew, guava, soursop, mango, sweetsop, pitanga, sapoti and grapes. The results obtained showed that the technological process used reduced significantly the fiber percentual of the fruit, determined by gravimetric non-ensymatic method particularly the guava, followed by the grapes, soursop, saoti, cashew, sweetsop and acerola. With the exception of mango and pitanga, all the frozen pulps tested do not seem to substitute, in terms of quantity of dietary fiber, the in natura fruit in the diet of healthy individuals. Considering the fact that these losses are variable, depending on the characteristics of the fruit which was processed, the inclusion of frozen pulps in the human diet in substitution to fruits will depend on quality control studies which may lead to a classification of the components of the mentioned fraction.

    Full Text Available As moscas-das-frutas são as principais pragas da fruticultura mundial. Consideradas chaves para a produção de citros, torna-se necessário o seu monitoramento, visando a evitar os danos diretos. O experimento teve como objetivos conhecer a variação populacional de Anastrepha fraterculus e a relação de sua população com danos em pomares orgânicos de Citrus sinensis, cultivar Céu e de C. sinensis x Citrus reticulata tangor 'Murcott'. Os dados foram coletados em 2003 e 2004 durante o período de maturação dos frutos, na região do vale do Caí, RS, Brasil. O número de moscas-das-frutas foi registrado, semanalmente, por meio de armadilhas McPhail, contendo suco de uva, a 25%. Danos aos frutos foram determinados pela razão entre frutos sadios e frutos danificados pela mosca. Registros meteorológicos de temperatura, umidade relativa e precipitação pluviométrica foram obtidos, em estação meteorológica distante 30 km das áreas experimentais. Verificou-se que, em condições ideais de precipitação pluvial, maiores foram as populações de A. fraterculus, espécie predominante na região. A população estimada capaz de causar danos aos frutos variou de acordo com o cultivar, sendo a laranjeira 'Céu' a mais susceptível. Os maiores picos populacionais ocorrem na fase de mudança de coloração dos frutos. Porém, na fase de maturação, as moscas causaram os maiores danos, dada a intolerância dos frutos ao ataque. Conclui-se que a infestação dos frutos de citros por A. fraterculus está relacionada com espécie e cultivar e com fatores climáticos, principalmente com a precipitação pluvial. O monitoramento constante da população de mosca-das-frutas é importante na determinação da infestação na colheita.

Essas espécies do grupo fraterculus distinguem-se unicamente com base em detalhes do ápice do acúleo, que por serem muito semelhantes, dificultam a identificação específica. A análise discriminante permitiu a separação das quatro espécies de Anastrepha, com base em oito medidas do acúleo. Portanto, essa é mais uma técnica para auxiliar as identificações de espécies de Anastrepha, como já acontece em muitos outros grupos de insetos.

    Full Text Available Introdução: A administração de medicamentos juntamente com sucos de frutas pode determinar variações na farmacocinética e farmacodinâmica, comprometendo a biodisponibilidade e meia-vida dos compostos envolvidos. Objetivo: Verificar e classificar informações sobre ocorrências de interações que resultam da co-administração de medicamentos e sucos de frutas. Materiais e Métodos: Foi realizada uma revisão na literatura a cerca do tema proposto. Os dados sobre interações foram obtidos de pesquisa em diferentes bancos de dados e livros relacionados, realizada no período de 2008/2009. O método utilizado no estudo incluiu a análise de informações obtidas a partir de bases de dados como PUBMED, SCIELO, BDENF, BBO e natural medicine comprehensive database, sendo que os descritores utilizados consistiram em: interações, interactions, sucos de frutas, fruit juice, CYP 450, P-glicoproteínas e OATP (organic anion transporter polypeptide. Resultados: Ficou evidente a existência de um número significativo de interações, identificadas a partir de estudos experimentais, casos-controle e relatos de caso. Referências sobre agravamento de um efeito ou ineficácia terapêutica, decorrentes da associação de fármacos com sucos de frutas, foram citadas por diversos autores. Conclusão: O estudo evidenciou que interações entre sucos de laranja e toranja consistem nas ocorrências mais comumente citadas, muitas vezes responsáveis por variações sobre a biodisponibilidade e meia-vida de fármacos o que, em última instância, determina variações na resposta terapêutica.Administering medications together with fruit juices may lead to variations in pharmacokinetics and pharmacodynamics, with repercussions on the bioavailability and half –life of the compounds. Pharmacokinetic mechanisms are usually related to intestinal and hepatic enzymes of cytochrome P-450 (CYP 450 interference, as well as in transporter enzymes of the mucosa (P

    En el cultivo de mango se evaluó el efecto de 'Arauca' (genotipo débil e 'Hilacha' (genotipo vigoroso –utilizados alternadamente como portainjerto o injerto intermedio– sobre la calidad de fructificación de las variedades Irwin, Tommy Atkins y Davis-Haden, en un huerto de 21 años en el departamento del Tolima (Colombia. Los parámetros evaluados de calidad de fruta fueron: diámetro y longitud del fruto, firmeza, pH, peso fresco, sólidos solubles totales (SST, acidez total titulable (ATT y relación SST/ATT. Mientras que las variedades mostraron diferencias estadísticas en todos los parámetros de calidad de fruta que fueron evaluados, los portainjertos no produjeron diferencia alguna sobre estos parámetros. Las variables diámetro del fruto, firmeza, pH y acidez titulable fueron influenciadas por el interinjerto, mientras que el peso fresco, la longitud del fruto, los sólidos solubles totales y la relación SST/ATT permanecieron inalterados. Hubo diferencias significativas entre las combinaciones evaluadas (variedad/interinjerto/portainjerto para todos los parámetros evaluados, con excepción de la firmeza. Por ejemplo, las combinaciones Tommy Atkins/Hilacha/ Arauca y Tommy Atkins/Arauca/Hilacha presentaron valores cercanos de peso de fruto. Otro tanto sucedió al comparar las combinaciones Tommy Atkins/Hilacha y Tommy Atkins/Hilacha/ Arauca, para este mismo parámetro. Esto sugiere que el uso de 'Arauca' como portainjerto o como interinjerto, le confiere mayor peso del fruto a la variedad 'Tommy Atkins' , a pesar de que 'Arauca' es un portainjerto menos vigoroso que 'Hilacha'.

    Full Text Available En este artículo propongo una lectura de las novelas mexicanas Púrpura, de Ana García Bergua, y Fruta verde, de Enrique Serna, como representaciones de la bisexualidad que se insertan en, y a la vez rompen con, una tradición literaria que retrata la homosexualidad masculina. Leo el empleo de la ironía y el performance de género en los textos como señalamiento de las contradicciones y dificultades sociales que conllevan la orientación bisexual. El diálogo de las obras con la tradición de la novela de formación problematiza la expresión de sexualidades no normativas y plantea una crítica de las identidades sexuales basadas en el binarismo hetero / homosexual. Sostengo que estas obras deben ser incluidas en y analizadas dentro de la tradición literaria mexicana que retrata sexualidades disidentes, entre las cuales la bisexualidad ha sido una identidad marginada. In this article I propose a reading of the Mexican novels Púrpura by Ana García Bergua and Fruta verde by Enrique Serna as portrayals of bisexuality that both form a part of and break with a literary tradition that portrays male homosexuality. I read the use of irony and gender performance in these texts as a signaling of the social contradictions and problems that come with the bisexual orientation. The dialogue of these works with the tradition of the novel of formation problematizes the expression of non-normative sexualities and critiques sexual identities based on the heter/homo binary. I argue that these works should be included in a Mexican literary tradition that represents dissident sexualities, among which bisexuality has been marginalized and underrepresented.

    Full Text Available O objetivo deste estudo foi descrever a freqüência de consumo de frutas, legumes e verduras por adultos de 20 a 69 anos de Pelotas, Rio Grande do Sul, Brasil, e analisar fatores associados. Foi realizado em 2006 um estudo transversal de base populacional, incluindo 972 adultos. A freqüência do consumo de frutas, legumes e verduras foi medida por meio de três perguntas referentes ao consumo habitual destes no ano anterior. O desfecho foi o consumo regular de frutas, legumes e verduras. Cerca de 1/5 da população adulta (20,9% consumia regularmente frutas, legumes e verduras. Indivíduos do sexo feminino, com 60 anos ou mais, das classes A e B, ex-fumantes e não sedentários apresentaram maior prevalência de consumo de frutas e legumes e verduras. A freqüência do consumo de frutas, legumes e verduras na população adulta residente no Município de Pelotas está aquém das recomendações atuais do Ministério da Saúde, em especial entre os homens mais jovens, de menor nível sócio-econômico e que não praticam atividade física no lazer. Políticas públicas que estimulem uma alimentação saudável são urgentemente necessárias.The study aimed to describe the frequency of fruit and vegetable intake among adults (20-69 years of age and to identify associated factors. This population-based study in 2006 included 972 adults in Pelotas, Southern Brazil.

    Full Text Available Resumo: O presente estudo examina a influência do aumento da disponibilidade intradomiciliar de refrigerantes e biscoitos sobre os efeitos de uma intervenção de promoção do consumo de frutas e hortaliças. Foram analisados os dados de 70 famílias que viviam em comunidades de baixa renda na cidade do Rio de Janeiro, Brasil, que foram selecionadas por meio de uma amostra probabilística estratificada e completaram registro alimentar de 30 dias antes e depois da intervenção. A intervenção contribuiu para um aumento significativo na disponibilidade intradomiciliar de frutas e hortaliças (+2,7 p.p.; IC95%: 1,5; 4,0, superando a tendência de estagnação na população brasileira. Já a aquisição de refrigerantes e biscoitos, que não foi objeto da intervenção, acompanhou a tendência crescente de consumo destes produtos (+5,8 p.p.; IC95%: 3,3; 8,4. As famílias que aumentaram a aquisição de refrigerantes e biscoitos apresentaram menores aumentos, ou decréscimos, na aquisição de frutas e hortaliças (p < 0,05 e tiveram uma chance quase quatro vezes menor de experimentar algum aumento na disponibilidade intradomiciliar de frutas e hortaliças.

    Full Text Available El presente artículo muestra un modelo causal, desarrollado a dos niveles, uno general basado en el comportamiento dinámico de la cadena de suministro de frutas, y otro específico para la implementación de tecnologías de trazabilidad en la cadena. Surge de la necesidad de identificar la dinámica de la implementación de tecnologías de trazabilidad en la cadena de frutas. La hipótesis dinámica establecida fue: “El comportamiento dinámico de planeación e implementación de tecnología genera un efecto en la transformación, calidad, asignación de recursos, inventarios y trazabilidad del sistema (cadena de suministros frutícola”. El modelo causal fue obtenido a partir de una detallada y rigurosa revisión de la literatura y de estudios específicos del sector de frutas en Colombia, sobre el tema de la trazabilidad en la cadena de suministro de alimentos a partir de las perspectivas de dinámica de sistemas, integración, optimización y tecnologías de trazabilidad. Existen pocos trabajos en trazabilidad con un enfoque como el abordado en este trabajo. El desarrollo permitió incluir, en los diagramas causales, una serie de factores no tenidos en cuenta en trabajos previos. Los resultados obtenidos a través del análisis causal propuesto, bajo la metodología de dinámica de sistemas, implican la inclusión del efecto de la implementación de tecnología de trazabilidad en la cadena de suministro de frutas y sus relaciones con la capacidad de inversión y la calidad de un producto.

    Full Text Available Vários autores apontam a importância do segmento varejista como indutor de mudanças nas cadeias produtivas de diferentes produtos. Particularmente, no que diz respeito às cadeias produtivas de frutas frescas pode-se observar a importância do segmento varejista como indutor de padrões de qualidade e de uma série de mudanças que se revelam por meio de ações tomadas pelos outros segmentos de maneira a atender suas exigências. No entanto, não há estudos que mostrem qual a intensidade desta ação e quais os elementos que podem influenciá-la. Sendo assim, o objetivo deste trabalho é caracterizar as transações entre produtores brasileiros de manga e uva e compradores europeus e as estruturas das cadeias de valor de manga e uva para exportação. Na parte conceitual foi utilizada a abordagem de Cadeia de Valor Global e de Economia dos Custos de Transação. O método escolhido foi o estudo de casos múltiplos, conduzido com duas cadeias produtivas, a de uva e a de manga, voltadas para exportação para o mercado europeu. Foram conduzidas entrevistas presenciais com produtores e exportadores brasileiros de manga e uva, bem como com importadores alemães, ingleses e holandeses, no período de 2004 a 2005. Os resultados indicam que os supermercados atuam de maneira diferenciada nos dois mercados estudados, o inglês e alemão. Nas transações entre supermercados ingleses na cadeia de valor de frutas frescas com produtores brasileiros há o gerenciador de categoria que é o agente responsável pela ligação entre produtores brasileiros e supermercados ingleses e predominam estruturas de governança híbridas. Já no mercado alemão, não há o gerenciador de categoria e predomina a estrutura de governança de mercado. Estas diferenças nas estruturas das cadeias de valor nos dois mercados têm implicações diretas na maneira de inserção dos produtores de frutas frescas de países em desenvolvimento no comércio global.The aim of this

    Full Text Available El cooperativismo agrario ha estado ligado desde sus orígenes al sector de las frutas y hortalizas, sector que arrastra desde hace años una problemática de carácter estructural, incrementada, sobretodo en el caso de la fruta, por las graves crisis de precios, la saturación de los mercados y una competencia creciente de las importaciones de terceros países. En este difícil marco, los productores deben seguir invirtiendo para mantener la competitividad y la rentabilidad de sus explotaciones, y las cooperativas, por su importancia económica, deben acometer políticas que permitan garantizar la viabilidad de dicho sector. En el presente trabajo realizamos un análisis del sector cooperativo frutícola catalán, con el fin de detectar sus puntos fuertes y débiles, así como posibles carencias y demandas. Las conclusiones muestran que las cooperativas son importantes en el sector de la fruticultura, debido sobretodo a su contribución activa a la conservación del territorio y su papel generador de empleo en numerosas zonas rurales. Pero se hace necesario la adopción de firmes decisiones y la implantación de medidas de apoyo que permitan garantizar los intereses de los socios y las necesidades de los consumidores./ The agricultural cooperatives have been linked from the origins to fruit and vegetable sector. This sector dragged on for years a structural problem, increased, especially in the case of fruit, for serious price crisis, the market saturation and increasing competition. In this difficult context, producers must keep investing to maintain competitiveness and profitability. The cooperatives, by their economic importance, should undertake policies to ensure the viability of this sector. In this paper we do an analysis of Catalan fruit cooperative sector, to identify their strengths and weaknesses, and possible deficiencies and demands. The findings show that cooperatives are important in the fruit growing sector, mainly due to their

    Hayes, D.

    1988-02-01

    Following an unexpected surge in electricity demand the Philippines has revised its medium term power development programme. The sharp increase in electricity consumption follows three years of slack demand due to civil disturbances before the end of the Macros administration and the election of Corazon Aquino as President in 1986. Originally, the Aquino government's medium term power development plans called for about 500MW of generating capacity to be installed between 1986 and 1992. The three proposed plants were scheduled for commissioning in 1991 and 1992. However, a spurt in power demand growth during the past nine months has caused concern among industrialists that power shortages could occur by the end of the decade. So additional capacity will be installed to prevent an anticipated shortfall in electricity supplies by the early 1990s.

    Full Text Available Introduction: Scars are psychologically distressing for the patients and have an impact on the quality of life and self esteem of the patients. Scar revision is an aesthetic skill which is mastered by plastic surgeons and encroached now by dermatosurgeons. Scars on the face are aesthetically unacceptable and various techniques have been improvised for making a scar aesthetically acceptable. Various types of techniques are used for scar revision like W plasty, Z plasty and VY plasty. Aims: To see the efficacy of various scar revision techniques including Z plasty, VY plasty and W plasty in 30 patients with disfiguring scars. Methods: We selected twenty patients of disfiguring scars for the study. The scars from various causes including trauma and burns were included in our study. Various techniques of scar revision include Z plasty, W plasty and VY plasty were performed according to the type and site of scar. Results: Male: female was 1.5: 1. The scar revision surgery yielded excellent results with minimal complications including haematoma formation, secondary infection and delayed healing seen in 5% patients each. Regarding the efficacy of scar revision, excellent improvement was seen in 60% patients, moderate improvement was seen in 30% patients and mild improvement was seen in 10% patients. Conclusions: Dermatologists can employ a number of surgical scar revision techniques. While some are better suited to treat specific types of scars, they can be used in combination with each other or with adjunctive therapies to achieve optimal results.

    Full Text Available Drosophila melanogaster, la mosca de la fruta, es un organismo genético modelo que en años recientes se ha usado exitosamente para estudiar el control del metabolismo y el crecimiento. A pesar de poseer algunas diferencias con las vías de señalización homólogas a las de los vertebrados, las semejanzas son profundas y claras. En D. melanogaster, la vía de la insulina, homóloga a la de los vertebrados, regula tanto el metabolismo como el crecimiento del organismo a través de un receptor membranal único. A su vez, esta vía –que conjunta lo que en vertebrados es la vía de la insulina y la de los péptidos parecidos a la insulina- está regulada por la ingesta de nutrientes (carbohidratos y proteínas y por el control hormonal (hormona del crecimiento, ecdisona, upd2, hormona adipocinética, Ilp8. En consecuencia, normalmente se obtiene un crecimiento adaptable a las condiciones nutricionales que influye, como en los vertebrados, en el promedio de vida y en la capacidad reproductiva con un tamaño típico y una diferenciación armónica, a tono con el bauplandel organismo. Por el contrario las mutaciones y desviaciones dan por resultado partes desproporcionadas, menor capacidad reproductiva, y disminución tanto del tamaño como de la proliferación, y hasta la muerte.

    Full Text Available A economia agrícola da região Norte Fluminense é, historicamente, dependente da atividade sucroalcooleira. Na tentativa de reduzir tal dependência, vêm sendo adotados incentivos ao desenvolvimento da fruticultura na região, particularmente através do “Programa Frutificar”. O presente trabalho visa a avaliar os impactos desse programa, sob a óticade sua contribuição para elevar a produção de frutas e diversificar a agricultura regional. A análise foi efetuada mediante o emprego do modelo , shift-sharede taxas geométricas de crescimento, e do Índice de Diversificação. De mão dessas análises, pode-se concluir que foi constatada a redução da área agrícola da região, particularmente associada à queda nas áreas cultivadas com cana-deaçúcar, arroz, milho e feijão. Por outro lado, no período sob estímulo do “Programa Frutificar”, verificouse aumento do cultivo das fruteiras: abacaxi, banana e coco-da-baía. Esta constatação é um indicativo da contribuição da fruticultura como fator de diversificação da economia agrícola regional. Cabe ressaltar que a economia da região Norte Fluminense é ainda fortemente dependente do setor sucroalcooleiro.

    Full Text Available O objetivo deste trabalho foi adequar as dietas artificiais para o desenvolvimento dos estágios de larva e adulto da mosca-das-frutas sul-americana (Anastrepha fraterculus. Para o estágio larval, foram testadas as seguintes dietas: D1, original, com 10 g de ágar; D2, modificada, com 3,6 g de ágar; e, D3, modificada, com bagaço seco de cana-de-açúcar. Para os adultos, foram testadas quatro dietas: A, levedura de cerveja + mel (2:1; B, açúcar refinado + extrato de levedura + gérmen de trigo cru (3:1:1; C, extrato de soja + açúcar mascavo + gérmen de trigo cru (3:1:1; e D, levedura seca de cervejaria + mel (2:1. Avaliaram-se os parâmetros biológicos de duração do período ovo-pupa, duração e viabilidade do estágio de pupa, massa média de pupas, razão sexual e duração e viabilidade do período ovo-adulto. O desenvolvimento larval em D1 e D2 foi semelhante e indicou que a criação de larvas pode ser realizada com 1/3 da quantidade de ágar da utilizada em D1. A utilização do bagaço seco de cana-de-açúcar, na dieta artificial, afetou negativamente o desenvolvimento larval. As dietas artificiais com levedura de cerveja + mel e com açúcar refinado + extrato de levedura + gérmen de trigo cru são as mais adequadas para a criação de adultos.

    Full Text Available OBJETIVO: Analisar o consumo de frutas, legumes e verduras (FLV de adolescentes e identificar fatores associados. MÉTODOS: Estudo transversal de base populacional com amostra representativa de 812 adolescentes de ambos os sexos de São Paulo, SP, em 2003. O consumo alimentar foi medido pelo recordatório alimentar de 24 horas. O consumo de FLV foi descrito em percentis e para investigar a associação entre a ingestão de FLV e variáveis explanatórias; foram utilizados modelos de regressão quantílica. RESULTADOS: Dos adolescentes entrevistados, 6,4% consumiram a recomendação mínima de 400 g/dia de FLV e 22% não consumiram nenhum tipo de FLV. Nos modelos de regressão quantílica, ajustados pelo consumo energético, faixa etária e sexo, a renda domiciliar per capita e a escolaridade do chefe de família associaram-se positivamente ao consumo de FLV, enquanto o hábito de fumar associou-se negativamente. Renda associou-se significativamente aos menores percentis de ingestão (p20 ao p55; tabagismo aos percentis intermediários (p45 ao p75 e escolaridade do chefe de família aos percentis finais de consumo de FLV (p70 ao p95. CONCLUSÕES: O consumo de FLV por adolescentes paulistanos mostrou-se abaixo das recomendações do Ministério da Saúde e é influenciado pela renda domiciliar per capita, pela escolaridade do chefe de família e pelo hábito de fumar.

    The original version of ASCE Standard 4, ''Seismic Analysis of Safety-Related Nuclear Structures'' was published in September 1986. It is ASCE policy to update its standards on a five year interval and the Working Group on Seismic Analysis of Safety Related Nuclear Structures was reconvened to formulate the revisions. The goal in updating the standard is to make sure that it is still relevant and that it incorporates the state of the practice in seismic engineering or, in some cases, where it has been demonstrated that state-of-the-art improvements need to be made to standard practice; new improvements are included. The contents of the new standard cover the same areas as the original version, with some additions. The contents are as follows: Input - response spectra and time histories; modeling of structures; analysis of structures; soil-structure interaction; input for subsystem analysis; special structures - buried pipes and conduits, earth-retaining walls, above-ground vertical tanks, raceways, and base-isolated structures; and an appendix providing seismic probabilistic risk assessment and margin assessment

  19. Contact activation: a revision.

    Science.gov (United States)

    Schmaier, A H

    1997-07-01

    In conclusion, a revised view of the contact system has been presented. This system has little to do with the initiation of hemostasis. Like lupus anticoagulants, deficiencies of contact proteins give prolonged APTTs but may be risk factors for thrombosis. BK from kininogens is a potent modulator of vascular biology inducing vasodilation, tissue plasminogen activator release, and prostacyclin liberation. Kininogens, themselves, are selective inhibitors of alpha-thrombin-induced platelet activation preventing alpha-thrombin from cleaving the cloned thrombin receptor after arginine41. Kininogens' alpha-thrombin inhibitory activity exists in intact kininogens, BK, and all of BK's breakdown products. HK also is the pivotal protein for contact protein assembly on endothelium. It is the receptor for prekallikrein which when bound to HK becomes activated to kallikrein by an endothelial cell enzyme system independent of activated forms of plasma factor XII. Prekallikrein activation on endothelial cells results in kinetically favorable single chain urokinase and plasminogen activation. Thus the "physiologic, negatively charged surface" for contact system activation is really the assembly of these proteins on cell membranes and activation by membrane-associated enzymes.

Os frutos colhidos de plantas nativas no início do estádio de amadurecimento foram selecionados e armazenados durante 18 dias à temperatura ambiente (17,1 a 26,9ºC. Os frutos foram lavados com água destilada, descascados, picados, congelados em nitrogênio líquido e liofilizados até massa constante. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições de 3 frutos. Os valores de pH e acidez titulável não variaram estatisticamente durante o amadurecimento. A atividade de amilase e os teores de amido diminuíram gradativamente com o aumento dos açúcares solúveis totais e não redutores, enquanto os teores dos redutores se mantiveram constantes. Os teores de pectinas totais e solúveis diminuíram, enquanto a atividade de pectinametilesterase manteve-se constante. As atividades das enzimas poligalacturonase e polimetilgalacturonase não foram detectadas no fruto. Observou-se diminuição dos teores de polifenóis e das atividades das enzimas peroxidase e polifenoloxidase e conseqüente diminuição do escurecimento da polpa do fruto.Physical-chemical, chemical and enzymatic modifications were studied during the ripening of "fruta-de-lobo" compared with those in other fruits.

    Full Text Available La inserción del Sureste mexicano en el proceso de globalización ha sido difícil. La desaparición de actividades económicas, la exclusión y la migración han sido manifestaciones de su deterioro en la última década. No obstante, la región cuenta con algunos nodos o ámbitos locales específicos cuyas actividades y productos tienen potencial para insertarse en las redes de producción-distribución globalizadas. En este sentido, el presente artículo analiza el desarrollo de la cadena de exportación de una fruta tropical (la piña fresca bajo la hipótesis de que el impulso innovador y fortalecimiento de las redes productivas locales en territorios del sureste mexicano está estrechamente vinculado a la formación de cadenas logísticas, así como al control operativo, tecnológico y espacio-temporal que los actores locales alcanzan sobre las mismas. El planteamiento teórico se apoya en el enfoque sistémico de la cadena logística, que prescinde de las divisiones conceptuales tajantes entre producción, distribución y consumo, al poner énfasis en la circulación, es decir, en los flujos, cuya capacidad de movilización es fundamental para articular, integrar y dar viabilidad a los territorios en un contexto de relaciones globalizadasThe insertion of the Mexican southeast region into the globalization process has been a difficult task. The loss of economic activity, exclusion, and migration have been signs of the region's deterioration in the last decade. Nonetheless, this region contains several local"nodes" or spheres whose products and activities have the potential to participate in global production-distribution networks. This paper analyzes the export chain development of a tropical fruit (pineapple under the hypothesis that innovation support and strengthening of local production networks in southeast Mexico are closely linked to the formation of logistic supply chains and technical and operative control undertaken by local

Procedeu-se à revisão da literatura e de site oficial de divulgação das políticas de SAN e de planejamento urbano de Belo Horizonte (MG, além da construção de mapas. Os programas de SAN no município atendem a mais de um milhão de pessoas por dia, incluindo iniciativas de incentivo à produção de alimentos, defesa e promoção do consumo alimentar, comercialização subsidiada de alimentos e refeições, e capacitação em alimentação. Verificou-se no município a concentração de estabelecimentos comerciais de FH, incluindo aqueles com subsídios públicos (feiras-livres e sacolões públicos, na região mais rica da cidade, com acesso limitado na periferia e territórios de serviços de promoção da saúde (Programa Academia da Saúde. Entretanto, o aumento de unidades de sacolões públicos e privados, feiras-livres e supermercados poderia favorecer o acesso a alimentos saudáveis nos territórios mais vulneráveis. Estes dados revelam a importância do monitoramento das políticas públicas, pela sociedade civil e representantes do governo, visando reduzir as iniquidades e contribuir para melhoria da qualidade de vida e o bem-estar social da população, além de colaborar para sistemas alimentares sustentáveis. Sugere-se que políticas públicas de SAN dialoguem com outras políticas, como as de saúde, planejamento urbano, assistência social, agricultura, dentre outras, de forma a promover a equidade e atender intersetorialmente às necessidades de comunidades mais vulneráveis.

    This report is a revision of the previous Hanford Environmental Dose Reconstruction (HEDR) Project modeling approach report. This revised report describes the methods used in performing scoping studies and estimating final radiation doses to real and representative individuals who lived in the vicinity of the Hanford Site. The scoping studies and dose estimates pertain to various environmental pathways during various periods of time. The original report discussed the concepts under consideration in 1991. The methods for estimating dose have been refined as understanding of existing data, the scope of pathways, and the magnitudes of dose estimates were evaluated through scoping studies

    Full Text Available A espécie Artocarpus altilis produz frutos popularmente conhecidos como fruta-pão. São climatéricos e contribuem com quantidades consideráveis de energia e fornecer os principais nutrientes da dieta. Podem ser consumidos cozidos, fritos ou torrados e em processos tecnológicos tendo potencial para ser empregados em biscoitos e comercializados como farinha. Na literatura são poucos os trabalhos que relatem as características desses frutos, principalmente da região Nordeste. Desta forma, objetivou-se avaliar a biometria e as características físico-químicas da fruta-pão coletada no município de Santa Rita, Paraíba, Brasil. Foram selecionados 30 frutos firmes em 3 estádios de maturação, com pedúnculo, casca verde e amarelada, látex presente e livres de lesões. Os frutos apresentaram em média diâmetro externo transversal e diâmetro externo longitudinal de 15,98 (± 0,12 e 13,11 (± 0,13 cm, respectivamente, bem como massa média de 1,52 (± 0,06 Kg e firmeza de 66,80 (± 1,13 N.

    In Norway, the proportion of revision knee arthroplasties increased from 6.9% in 1994 to 8.5% in 2011. However, there is limited information on the epidemiology and causes of subsequent failure of revision knee arthroplasty. We therefore studied survival rate and determined the modes of failure of aseptic revision total knee arthroplasties. This study was based on 1,016 aseptic revision total knee arthroplasties reported to the Norwegian Arthroplasty Register between 1994 and 2011. Revisions done for infections were not included. Kaplan-Meier and Cox regression analyses were used to assess the survival rate and the relative risk of re-revision with all causes of re-revision as endpoint. 145 knees failed after revision total knee arthroplasty. Deep infection was the most frequent cause of re-revision (28%), followed by instability (26%), loose tibial component (17%), and pain (10%). The cumulative survival rate for revision total knee arthroplasties was 85% at 5 years, 78% at 10 years, and 71% at 15 years. Revision total knee arthroplasties with exchange of the femoral or tibial component exclusively had a higher risk of re-revision (RR = 1.7) than those with exchange of the whole prosthesis. The risk of re-revision was higher for men (RR = 2.0) and for patients aged less than 60 years (RR = 1.6). In terms of implant survival, revision of the whole implant was better than revision of 1 component only. Young age and male sex were risk factors for re-revision. Deep infection was the most frequent cause of failure of revision of aseptic total knee arthroplasties.

  7. The nuclear liability conventions revised

    International Nuclear Information System (INIS)

    Reyners, P.

    2004-01-01

    The signature on 12 February 2004 of the Protocols amending respectively the 1960 Paris Convention and the 1963 Brussels Supplementary Convention was the second step of the process of modernisation of the international nuclear liability regime after the adoption in September 1997 of a Protocol revising the 1963 Vienna Convention and of a new Convention on Supplementary Compensation for Nuclear Damage. The common objective of the new instruments is to provide more funds to compensate a larger number of potential victims in respect of a broader range of damage. Another goal of the revision exercise was to maintain the compatibility between the Paris and Vienna based systems, a commitment enshrined in the 1988 Joint Protocol, as well as to ascertain that Paris/Brussels countries could also become a Party to the Convention on Supplementary Compensation. However, while generally consistent vis a vis the Joint Protocol, the provisions of the Paris and Vienna Conventions, as revised, differ on some significant aspects. Another remaining issue is whether the improved international nuclear liability regime will succeed in attracting in the future a larger number of countries, particularly outside Europe, and will so become truly universal. Therefore, the need for international co-operation to address these issues, to facilitate the adoption of new implementing legislation and to ensure that this special regime keeps abreast of economic and technological developments, is in no way diminished after the revision of the Conventions.(author)

    Full Text Available Neste trabalho, foram caracterizados seis tipos de material inerte, utilizados na secagem de polpa de frutas em leito de jorro. Determinou-se o ângulo de repouso das partículas, com e sem adição de água e de polpa de diversas frutas tropicais. Correlacionou-se a escoabilidade com as propriedades das partículas e com a composição química das polpas. Analisou-se a influência do ângulo de repouso sobre o desempenho do secador, no que se refere à produção. Os resultados mostraram que, em geral, as polpas com elevadas concentrações de gordura e sólidos insolúveis e baixos teores de açúcares redutores, facilitam a escoabilidade. Uma análise dos resultados obtidos na secagem de polpa de frutas tropicais, utilizando-se partículas de poliestireno de baixa densidade, como material inerte, mostrou que, embora a escoabilidade permita a obtenção de menores vazões de jorro mínimo, em relação ao desempenho do secador, pode não favorecer uma produção maior de pó.In this work six types of inert particles were characterized and analyzed for drying tropical fruit pulps. The repose angle was determined with and without the addition of water and pulp of various tropical fruits. The bed flowability was related to the particle properties and chemical composition of pulps. The influence of the repose angle on the drying performance was analyzed. It was also verified that the composition of pulps influenced the bed flowability. The global analysis showed that the pulps with high lipids and insoluble solids content and low reducing sugar content improved the bed flowability. The results obtained with the drying of the fruit pulps using low-density polystyrene granules as inert particles showed that high flowabilities lead to lower minimum spout flow rates, but do not necessarily lead to the highest powder production.

    Full Text Available Resumo A estimativa do crescimento populacional mundial de nove bilhões de pessoas, em 2050, estabelece um grande desafio para os próximos anos, considerando os problemas atuais de insegurança alimentar e o fornecimento de alimentos saudáveis, num mundo, predominantemente, de pessoas vivendo em regiões urbanas. A importância da dieta na saúde é indiscutível, sendo que, a cada dia que passa, o consumidor está mais consciente de que a saúde está diretamente relacionada a uma dieta balanceada e segura. As tecnologias aplicadas na pós-colheita de frutas e hortaliças que continuam com seu metabolismo ativo buscam manter a qualidade através dos parâmetros aparência, textura, sabor, valor nutritivo e segurança alimentar, bem como reduzir perdas qualitativas e quantitativas entre a colheita e o consumo. A combinação de tecnologias, como resfriamento rápido, refrigeração e utilização de embalagens com atmosferas modificadas ativas e passivas, aplicadas na pós-colheita, precisa estar aliada a uma adequada gestão de temperatura para cada produto, em toda a cadeia de distribuição. Assim, conforme o histórico de temperatura desde a colheita até os locais de vendas no varejo, a estimativa da vida útil torna-se uma variável altamente dinâmica. Tecnologias de RFID (Radio Frequency Identification - Identificação por Rádio Frequência integradas a sensores podem revolucionar o transporte e o manuseio de produtos perecíveis, por meio de leituras precisas e contínuas das condições do ambiente de conservação durante a logística, interpretadas por modelos matemáticos que estimam a vida útil restante.

    Full Text Available Dado que el agua es muy buen solvente, las aguas que se usan para riego contienen algunas sales disueltas. La salinidad restringe la disponibilidad de este líquido para las plantas mediante la reducción del potencial hídrico en el suelo. La salinidad también tiene un impacto sobre la fisiología de la producción de las plantas. Es posible observar lesiones en plantas expuestas a niveles altos de salinidad. Este ensayo fue realizado para evaluar la relación entre la salinidad por NaCl, la producción y la calidad de fruta, en los cultivares de fresa ‘Chandler’, ‘Sweet Charlie’ y ‘Camarosa’ cultivados en invernadero, en materas con suelo salinizado. Se compararon cinco niveles de la sal (0, 20, 40, 60 y 80 mM de NaCl los cuales indujeron diferentes valores de conductividad eléctrica (EC (2,68; 6,08; 8,24; 9,98 y 12,62 dS.m-1, respectivamente. Los diversos niveles de EC se obtuvieron agregando el NaCl al suelo, progresivamente. La producción y la calidad de la fruta fueron afectadas negativamente, por los tratamientos probados. De igual manera, el contenido de azúcares en los frutos fue influido por los diferentes niveles de sal. Los contenidos de sólidos solubles totales y la acidez titulable en frutas se incrementaron con el aumento en la EC. Mientras que la acumulación de la materia seca en las raíces mostró un aumento proporcional con el nivel del NaCl en el substrato, los frutos presentaron una tendencia opuesta. Aunque los síntomas típicos del estrés tales como retraso del crecimiento y la producción reducida de fruta fueron observados en los cultivares de fresa evaluados, ‘Sweet Charlie’ fue menos sensible a la salinidad.Since water is a very good solvent, all irrigation waters contain some dissolved salts. Salinity restricts the availability of water to plants by lowering the total water potential in the soil. Salinity also has an impact on crop physiology and yield.

Os resultados sobre o perfil do consumidor de frutas nas cidades pesquisadas sinalizam uma preocupação com as características do produto (saudáveis e saborosos, com o preço e com facilidades de acesso na compra. Os resultados apontam também para a necessidade de maiores estudos sobre a importância da informação relacionada aos aspectos mais valorizados (características do produto e preço na estrutura de consumo.Scientific studies analyzing consumers profile and decision-making processes play an important role on companies' strategies and vertical coordination action to increase efficiency on food chains. This research mapped the profile of food consumers on medium size cities on the state of Sao Paulo, Brazil. The sample considered 404 consumers in sale spots of 5 cities: Botucatu, Avaré, Jaboticabal, Ilha Solteira and Tupã. The results suggested that consumers of the 5 cities are concerned about fruit attributes like healthiness and flavor, but not neglecting price and access to market facilities. These results highlighted the importance of marketing actions to emphasize important characteristics valued by consumers, like price and product related attributes.

    Full Text Available As moscas-das-frutas do gênero Anastrepha são uma praga-chave na cultura do pessegueiro no Paraná. Atrativos alimentares foram testados para determinar a sua eficiência no monitoramento de moscas-das-frutas capturadas em frascos caça-moscas McPhail. O experimento foi conduzido por três anos, sendo que, em 2002, foram testados como atrativo o suco de uva da marca Maguari®, o hidrolisado enzimático de proteína da marca BioAnastrepha® e o vinagre da marca Chemin Agrin®. Nos dois anos seguintes, o vinagre foi substituído pelo composto protéico hidrolisável da marca Torula®. As substâncias atrativas à base de proteína foram as mais eficientes na captura de Anastrepha spp., e as capturas ocorreram antecipadas em relação ao suco de uva. De acordo com os resultados, recomendam-se atrativos à base de proteína para monitoramento de Anastrepha spp em pessegueiro, na Lapa.Fruit flies of Anastrepha genus are a key pest in peach trees in Paraná. Food attractants were tested to determine their efficiency in monitoring fruit flies captured in McPhail fly traps. The experiment was conducted over a period of three years. In 2002 the following attractors were tested: Maguari® brand grape juice, BioAnastrepha® brand hydrolyzed enzymatic protein and Chemin Agrin® vinegar. Over the next two years, the vinegar was replaced by Torula® hydrolyzed protein compound. Protein-based attractants were the most efficient in trapping Anastrepha spp. and captured flies earlier comparing to grape juice. According to the results, the use of protein-based attractants for monitoring Anastrepha spp in the Lapa peach trees was recommended.

    With rapidly changing dietary environment, dietary guidelines for Koreans were revised and relevant action guides were developed. First, the Dietary Guidelines Advisory Committee was established with experts and government officials from the fields of nutrition, preventive medicine, health promotion, agriculture, education and environment. The Committee set dietary goals for Koreans aiming for a better nutrition state of all after a thorough review and analysis of recent information related to nutritional status and/or problems of Korean population, changes in food production/supply, disease pattern, health policy and agricultural policy. Then, the revised dietary guidelines were proposed to accomplish these goals in addition to 6 different sets of dietary action guides to accommodate specific nutrition and health problems of respective age groups. Subsequently, these guidelines and guides were subjected to the focus group review, consumer perception surveys, and a public hearing for general and professional comments. Lastly, the language was clarified in terms of public understanding and phraseology. The revised Dietary guidelines for Koreans are as follows: eat a variety of grains, vegetables, fruits, fish, meat, poultry and dairy products; choose salt-preserved foods less, and use less salt when you prepare foods; increase physical activity for a healthy weight, and balance what you eat with your activity; enjoy every meal, and do not skip breakfast; if you drink alcoholic beverages, do so in moderation; prepare foods properly, and order sensible amounts; enjoy our rice-based diet.

  15. Re-visions of rationality?

    Science.gov (United States)

    Newell, Ben R

    2005-01-01

    The appeal of simple algorithms that take account of both the constraints of human cognitive capacity and the structure of environments has been an enduring theme in cognitive science. A novel version of such a boundedly rational perspective views the mind as containing an 'adaptive toolbox' of specialized cognitive heuristics suited to different problems. Although intuitively appealing, when this version was proposed, empirical evidence for the use of such heuristics was scant. I argue that in the light of empirical studies carried out since then, it is time this 'vision of rationality' was revised. An alternative view based on integrative models rather than collections of heuristics is proposed.

    Results from space have been unexpected and not predictable from the results of ground-based simulations. Therefore, the concept of how weightlessness and gravity modulates the regulation of body fluids must be revised and a new simulation model developed. The main questions to ask in the future...... are the following: Does weightlessness induce a diuresis and natriuresis during the initial hours of space flight leading to an extracellular and intravascular fluid volume deficit? Can sodium in excess be stored in a hitherto unknown way, particularly during space flight? Why are fluid and sodium retaining systems...

    In connection with the forthcoming revision of the Coniferae for the Flora Malesiana, the author thought it necessary to revise the genus Podocarpus. Although this genus has a substantial representation in Malesia (30 species), the revision is too involved to be appropriate with the Flora Malesiana per se. One new subgenus and 17 new sections are described, and 94 species are enumerated, of which 11 species and 1 variety are described as new, and 3 varieties have been raised to specific rank....

  20. Revised nonstochastic health effects models

    International Nuclear Information System (INIS)

    Yaniv, S.S.; Scott, B.R.

    1991-01-01

    In 1989, the U.S. Nuclear Regulatory Commission (NRC) published a revision of the 1985 report, Health Effects Models for Nuclear Power Plant Accident Consequence Analysis, NUREG/CR-4214, that included models for early occurring and continuing nonstochastic effects, cancers and thyroid nodules, and genetic effects. This paper discusses specific models for lethality from early occurring and continuing effects. For brevity, hematopoietic-syndrome lethality is called hematopoietic death; pulmonary-syndrome lethality is called pulmonary death; and gastrointestinal syndrome lethality is called gastrointestinal death. Two-parameter Weibull risk functions are recommended for estimating the risk of hematopoietic, pulmonary, or gastrointestinal death. The risks are obtained indirectly by using hazard functions; as a result, this type of approach has been called hazard-function modeling and the models generated are called hazard-function models. In the 1989 NUREG/CR-4214 report, changes were made in the parameter values for a number of effects, and the models used to estimate hematopoietic and pulmonary deaths were substantially revised. Upper and lower estimates of model parameters are provided for all early health effects models. In this paper, we discuss the 1989 models for hematopoietic and pulmonary deaths, highlighting the differences between the 1989 and 1985 models. In addition, we give the reasons for which the 1985 models were modified

    Most teaching of child health in Cardiff takes place in block attachments of 8 weeks. There is an introductory seminar of 2 days followed by a 6-week clinical attachment in a district general hospital in Wales, and then a revision period of one week designed to help students formalize and structure their basic knowledge and to clarify aspects of child health which they may have had difficulty in understanding. The revision programme has to take into account: the short time available, the small number of teaching staff, the most relevant basic knowledge and active participation by the student. This paper describes how this week has been improved through the use of student-initiated revision (SIR). The students' appraisal of this revision and in particular SIR is presented.

    CERN Document Server

    Hansson, Sven Ove

    2017-01-01

    This book provides a critical examination of how the choice of what to believe is represented in the standard model of belief change. In particular the use of possible worlds and infinite remainders as objects of choice is critically examined. Descriptors are introduced as a versatile tool for expressing the success conditions of belief change, addressing both local and global descriptor revision. The book presents dynamic descriptors such as Ramsey descriptors that convey how an agent’s beliefs tend to be changed in response to different inputs. It also explores sentential revision and demonstrates how local and global operations of revision by a sentence can be derived as a special case of descriptor revision. Lastly, the book examines revocation, a generalization of contraction in which a specified sentence is removed in a process that may possibly also involve the addition of some new information to the belief set.

    2010-09-01

    The Defense Land Fallout Interpretive Code (DELFIC) was originally released in 1968 as a tool for modeling fallout patterns and for predicting exposure rates. Despite the continual advancement of knowledge of fission yields, decay behavior of fission products, and biological dosimetry, the decay data and logic of DELFIC have remained mostly unchanged since inception. Additionally, previous code revisions caused a loss of conservation of radioactive nuclides. In this report, a new revision of the decay database and the Particle Activity Module is introduced and explained. The database upgrades discussed are replacement of the fission yields with ENDF/B-VII data as formatted in the Oak Ridge Isotope Generation (ORIGEN) code, revised decay constants, revised exposure rate multipliers, revised decay modes and branching ratios, and revised boiling point data. Included decay logic upgrades represent a correction of a flaw in the treatment of the fission yields, extension of the logic to include more complex decay modes, conservation of nuclides (including stable nuclides) at all times, and conversion of key variables to double precision for nuclide conservation. Finally, recommended future work is discussed with an emphasis on completion of the overall radiation physics upgrade, particularly for dosimetry, induced activity, decay of the actinides, and fractionation.

    With the failure of thermal capsulorrhaphy for shoulder instability, there have been concerns with capsular thinning and capsular necrosis affecting revision surgery. To report the findings at revision surgery for failed thermal capsulorrhaphy and to evaluate the technical effects on subsequent revision capsular plication. Case series; Level of evidence, 4. Fourteen patients underwent arthroscopic evaluation and open reconstruction for a failed thermal capsulorrhaphy. The cause of the failure, the quality of the capsule, and the ability to suture the capsule were recorded. The patients were evaluated at follow-up for failure, which was defined as recurrent subluxations or dislocations. The origin of the instability was traumatic (n = 6) or atraumatic (n = 8). At revision surgery in the traumatic group, 4 patients sustained failure of the Bankart repair with capsular laxity, and the others experienced capsular laxity alone. In the atraumatic group, all patients experienced capsular laxity as the cause of failure. Of the 14 patients, the capsule quality was judged to be thin in 5 patients and ablated in 1 patient. A glenoid-based capsular shift could be accomplished in all 14 patients. At follow-up (mean, 35.4 months; range, 22 to 48 months), 1 patient underwent revision surgery and 1 patient had a subluxation, resulting in a failure rate of 14%. Recurrent capsular laxity after failed thermal capsular shrinkage is common and frequently associated with capsular thinning. In most instances, the capsule quality does not appear to technically affect the revision procedure.

    Although the current literature discusses mesh complications including pain, as well as suggesting different techniques for removing mesh, there is little literature regarding pain outcomes after surgical removal or revision. The purpose of this study is to determine if surgical removal or revision of vaginal mesh improves patient's subjective complaints of pelvic pain associated with original placement of mesh. After obtaining approval from the Vanderbilt University Medical Center Institutional Review Board, a retrospective review of female patients with pain secondary to previous mesh placement who underwent excision or revision of vaginal mesh from January 2000 to August 2012 was performed. Patient age, relevant medical history including menopause status, previous hysterectomy, smoking status, and presence of diabetes, fibromyalgia, interstitial cystitis, and chronic pelvic pain, was obtained. Patients' postoperative pain complaints were assessed. Of the 481 patients who underwent surgery for mesh revision, removal or urethrolysis, 233 patients met our inclusion criteria. One hundred and sixty-nine patients (73 %) reported that their pain improved, 19 (8 %) reported that their pain worsened, and 45 (19 %) reported that their pain remained unchanged after surgery. Prior history of chronic pelvic pain was associated with increased risk of failure of the procedure to relieve pain (OR 0.28, 95 % CI 0.12-0.64, p = 0.003). Excision or revision of vaginal mesh appears to be effective in improving patients' pain symptoms most of the time. Patients with a history of chronic pelvic pain are at an increased risk of no improvement or of worsening pain.

    The survivorship of implants after revision total hip arthroplasty and risk factors associated with re-revision are not well defined. We evaluated the re-revision rate with use of the institutional total joint replacement registry. The purpose of this study was to determine patient, implant, and surgeon factors associated with re-revision total hip arthroplasty. A retrospective cohort study was conducted. The total joint replacement registry was used to identify patients who had undergone revision total hip arthroplasty for aseptic reasons from April 1, 2001, to December 31, 2010. The end point of interest was re-revision total hip arthroplasty. Risk factors evaluated for re-revision total hip arthroplasty included: patient risk factors (age, sex, body mass index, race, and general health status), implant risk factors (fixation type, bearing surface, femoral head size, and component replacement), and surgeon risk factors (volume and experience). A multivariable Cox proportional hazards model was used. Six hundred and twenty-nine revision total hip arthroplasties with sixty-three (10%) re-revisions were evaluated. The mean cohort age (and standard deviation) was 57.0 ± 12.4 years, the mean body mass index (and standard deviation) was 29.5 ± 6.1 kg/m(2), and most of the patients were women (64.5%) and white (81.9%) and had an American Society of Anesthesiologists score of associated with the risk of re-revision. For every ten-year increase in patient age, the hazard ratio for re-revision decreases by a factor of 0.72 (95% confidence interval, 0.58 to 0.90). For every five revision surgical procedures performed by a surgeon, the risk of revision decreases by a factor of 0.93 (95% confidence interval, 0.86 to 0.99). At the time of revision, a new or retained cemented femoral implant or all-cemented hip implant increases the risk of revision by a factor of 3.19 (95% confidence interval, 1.22 to 8.38) relative to a retained or new uncemented hip implant.

    2005-01-01

    To evaluate the problems encountered on revising a multiply operated nose and the methods used in correcting such problems. The study included 50 cases presenting for revision rhinoplasty after having had 2 or more previous rhinoplasties. An external rhinoplasty approach was used in all cases. Simultaneous septal surgery was done whenever indicated. All cases were followed for a mean period of 32 months (range, 1.5-8 years). Evaluation of the surgical result depended on clinical examination, comparison of pre- and postoperative photographs, and degree of patients' satisfaction with their aesthetic and functional outcome. Functionally, 68% suffered nasal obstruction that was mainly caused by septal deviations and nasal valve problems. Aesthetically, the most common deformities of the upper two thirds of the nose included pollybeak (64%), dorsal irregularities (54%), dorsal saddle (44%), and open roof deformity (42%), whereas the deformities of lower third included depressed tip (68%), tip contour irregularities (60%), and overrotated tip (42%). Nasal grafting was necessary in all cases; usually more than 1 type of graft was used in each case. Postoperatively, 79% of the patients, with preoperative nasal obstruction, reported improved breathing; 84% were satisfied with their aesthetic result; and only 8 cases (16%) requested further revision to correct minor deformities. Revision of a multiply operated nose is a complex and technically demanding task, yet, in a good percentage of cases, aesthetic as well as functional improvement are still possible.

    Full Text Available Corrective feedback, the necessity of providing it, and how it should be provided has been one of the hot topics in the area of ELT. Amid continuing controversies over whether providing feedback helps L2 learners improve their writing accuracy, many research studies have been undertaken to compare the relative effectiveness of different types of feedback. However, the difference between two types of indirect corrective feedback, namely indication and indication plus location, have not been properly examined yet. Motivated to narrow this gap, this study is designed to compare two groups of Iranian learners, each revising their papers based on one of the aforementioned options. For data analysis, a series of independent samples t tests were employed. The results revealed that the difference between the two groups in their reduction of errors from the original draft to the revision of each task followed a growing trend and became significant. Nonetheless, the difference in accuracy of new pieces of writing fell short of significance. Finally, it was found that error reduction in revision stage cannot be considered as learning. The results of the study, discussed in relation to that of others, implicate that the purpose for which feedback is provided is essential in determining the type of feedback; more explicit feedback is better for revising purposes while more implicit feedback is good for learning purposes.

    Garcia, Susan E.; Giannelli, Joseph F.

    2014-01-01

    BWRVIP-190: BWR Water Chemistry Guidelines – 2008 Revision has been revised. The revision committee consisted of U.S. and non-U.S. utilities (members of the BWR Vessel and Internals Protection (BWRVIP) Mitigation Committee), reactor system manufacturers, fuel suppliers, and EPRI and industry experts. The revised document, BWRVIP-190 Revision 1, was completely reformatted into two volumes, with a simplified presentation of water chemistry control, diagnostic and good practice parameters in Volume 1 and the technical bases in Volume 2, to facilitate use. The revision was developed in parallel and in coordination with preparation of the Fuel Reliability Guidelines Revision 1: BWR Fuel Cladding Crud and Corrosion. Guidance is included for plants operating under normal water chemistry (NWC), moderate hydrogen water chemistry (HWC-M), and noble metal application (GE-Hitachi NobleChem™) plus hydrogen injection. Volume 1 includes significant changes to BWR feedwater and reactor water chemistry control parameters to provide increased assurance of intergranular stress corrosion cracking (IGSCC) mitigation of reactor materials and fuel reliability during all plant conditions, including cold shutdown (≤200°F (93°C)), startup/hot standby (>200°F (93°C) and ≤ 10%) and power operation (>10% power). Action Level values for chloride and sulfate have been tightened to minimize environmentally assisted cracking (EAC) of all wetted surfaces, including those not protected by hydrogen injection, with or without noble metals. Chemistry control guidance has been enhanced to minimize shutdown radiation fields by clarifying targets for depleted zinc oxide (DZO) injection while meeting requirements for fuel reliability. Improved tabular presentations of parameter values explicitly indicate levels at which actions are to be taken and required sampling frequencies. Volume 2 provides the technical bases for BWR water chemistry control for control of EAC, flow accelerated corrosion

    2014-01-01

    EPRI periodically updates the PWR Primary Water Chemistry Guidelines as new information becomes available and as required by NEI 97-06 (Steam Generator Program Guidelines) and NEI 03-08 (Guideline for the Management of Materials Issues). The last revision of the PWR water chemistry guidelines identified an optimum primary water chemistry program based on then-current understanding of research and field information. This new revision provides further details with regard to primary water stress corrosion cracking (PWSCC), fuel integrity, and shutdown dose rates. A committee of industry experts, including utility specialists, nuclear steam supply system (NSSS) and fuel vendor representatives, Institute of Nuclear Power Operations (INPO) representatives, consultants, and EPRI staff collaborated in reviewing the available data on primary water chemistry, reactor water coolant system materials issues, fuel integrity and performance issues, and radiation dose rate issues. From the data, the committee updated the water chemistry guidelines that all PWR nuclear plants should adopt. The committee revised guidance with regard to optimization to reflect industry experience gained since the publication of Revision 6. Among the changes, the technical information regarding the impact of zinc injection on PWSCC initiation and dose rate reduction has been updated to reflect the current level of knowledge within the industry. Similarly, industry experience with elevated lithium concentrations with regard to fuel performance and radiation dose rates has been updated to reflect data collected to date. Recognizing that each nuclear plant owner has a unique set of design, operating, and corporate concerns, the guidelines committee has retained a method for plant-specific optimization. Revision 7 of the Pressurized Water Reactor Primary Water Chemistry Guidelines provides guidance for PWR primary systems of all manufacture and design. The guidelines continue to emphasize plant

  10. Revised National Pressure Ulcer Advisory Panel Pressure Injury Staging System: Revised Pressure Injury Staging System.

    Science.gov (United States)

    Edsberg, Laura E; Black, Joyce M; Goldberg, Margaret; McNichol, Laurie; Moore, Lynn; Sieggreen, Mary

    Our understanding of pressure injury etiology and development has grown in recent years through research, clinical expertise, and global interdisciplinary expert collaboration. Therefore, the National Pressure Ulcer Advisory Panel (NPUAP) has revised the definition and stages of pressure injury. The revision was undertaken to incorporate the current understanding of the etiology of pressure injuries, as well as to clarify the anatomical features present or absent in each stage of injury. An NPUAP-appointed Task Force reviewed the literature and created drafts of definitions, which were then reviewed by stakeholders and the public, including clinicians, educators, and researchers around the world. Using a consensus-building methodology, these revised definitions were the focus of a multidisciplinary consensus conference held in April 2016. As a result of stakeholder and public input, along with the consensus conference, important changes were made and incorporated into the new staging definitions. The revised staging system uses the term injury instead of ulcer and denotes stages using Arabic numerals rather than Roman numerals. The revised definition of a pressure injury now describes the injuries as usually occurring over a bony prominence or under a medical or other device. The revised definition of a Stage 2 pressure injury seeks to clarify the difference between moisture-associated skin damage and injury caused by pressure and/or shear. The term suspected has been removed from the Deep Tissue Pressure Injury diagnostic label. Each definition now describes the extent of tissue loss present and the anatomical features that may or may not be present in the stage of injury. These important revisions reflect the methodical and collaborative approach used to examine the available evidence and incorporate current interdisciplinary clinical expertise into better defining the important phenomenon of pressure injury etiology and development.

  11. A revised Self- and Family Management Framework.

    Science.gov (United States)

    Grey, Margaret; Schulman-Green, Dena; Knafl, Kathleen; Reynolds, Nancy R

    2015-01-01

    Research on self- and family management of chronic conditions has advanced over the past 6 years, but the use of simple frameworks has hampered the understanding of the complexities involved. We sought to update our previously published model with new empirical, synthetic, and theoretical work. We used synthesis of previous studies to update the framework. We propose a revised framework that clarifies facilitators and barriers, processes, proximal outcomes, and distal outcomes of self- and family management and their relationships. We offer the revised framework as a model that can be used in studies aimed at advancing self- and family management science. The use of the framework to guide studies would allow for the design of studies that can address more clearly how self-management interventions work and under what conditions.

    2014-10-01

    This Association of Vision Science Librarians revision of the "Standards for Vision Science Libraries" aspires to provide benchmarks to address the needs for the services and resources of modern vision science libraries (academic, medical or hospital, pharmaceutical, and so on), which share a core mission, are varied by type, and are located throughout the world. Through multiple meeting discussions, member surveys, and a collaborative revision process, the standards have been updated for the first time in over a decade. While the range of types of libraries supporting vision science services, education, and research is wide, all libraries, regardless of type, share core attributes, which the standards address. The current standards can and should be used to help develop new vision science libraries or to expand the growth of existing libraries, as well as to support vision science librarians in their work to better provide services and resources to their respective users.

  2. Revised inspection program for nuclear power plants

    International Nuclear Information System (INIS)

    1978-01-01

    The United States Nuclear Regulatory Commission (NRC) regulates nuclear power plants to assure adequate protection of the public and the environment from the dangers associated with nuclear materials. NRC fulfills this responsibility through comprehensive safety reviews of nuclear facilities, licensing of organizations that use nuclear materials, and continuing inspection. The NRC inspection program is currently conducted from the five regional offices in or near Philadelphia, Atlanta, Chicago, Dallas and San Francisco. Inspectors travel from the regional offices to nuclear power plants in various phases of construction, test and operation in order to conduct inspections. However, in June 1977 the Commission approved a revision to the inspection program that will include stationing inspectors at selected plants under construction and at all plants in operation. In addition, the revised program provides for appraising the performance of licensees on a national basis and involves more direct measurement and observation by NRC inspectors of work and tests in progress. The program also includes enhanced career management consisting of improved training and career development for inspectors and other professionals. The report was requested in the Conference Report on the NRC Authorization for Appropriations for Fiscal Year 1978. The report provides a discussion of the basis for both the current and revised inspection programs, describes these programs, and shows how the NRC inspection force will be trained and utilized. In addition, the report includes a discussion of the actions that will be taken to assure the objectivity of inspectors

    Facial scaring is considered one of the most difficult cosmetic problems for any plastic surgeon to solve. The condition is more difficult if the direction of the scar is not parallel to relaxed skin tension lines. Attempts to manage this difficult situation included revisions using geometric designs, Z plasties or W plasties to camouflage the straight line visible scaring. The use of long-lasting resorbable sutures was tried too. Recently, the use of botulinum toxin during revision improved the results. Fractional CO2 lasers, microfat grafts, and platelet-rich plasma were added to the armamentarium. The scar is least visible if placed in the junction between the facial subunits. The aim of this study is to investigate the use of the subunit principle to improve the results of scar revision. Four patients were included in this study. Tissue expansion of the intact part of the subunit allowed shifting the scar to the junction between the affected subunit and the adjacent one. Tissue expansion, delivery of the expanders, and advancement of the flaps were successful in all patients. The fact that this is a 2-stage procedure and sacrifices some of the intact skin from the affected facial subunit, makes this technique reserved to patients with ugly facial scars who are ambitious to improve their appearance.

    2012-01-01

    International standards from nuclear power plant operation area are being frequently upgraded and revised in accordance with the continuous improvement philosophy. This philosophy applies also to the area of Quality Assurance, which has also undergone significant improvement since the early 1950s. Besides just nuclear industry, there are also other international quality standards that are being continuously developed and revised, bringing needs for upgrades also in the nuclear application. Since the beginning of Krsko NPP construction, the overall Quality Assurance program and its applicable procedures were in place to assure that all planned and systematic actions necessary to provide adequate confidence that an item or service will satisfy given requirements to quality, are in place. The overall requirements for quality as one of the major objectives for Krsko NPP operation are also set forth in the Updated Safety Analyses Report, the document that serves as a base for operating license. During more than 30 years of Krsko NPP operation, the quality requirements and related documents were revised and upgraded in several attempts. The latest revision 6 of QD-1, Quality Assurance Plan was issued during the year 2011. The bases for the revision were: Changes of the Slovenian regulatory requirements (ZVISJV, JV5, JV9?), Changes of Krsko NPP licensing documents (USAR section 13?), SNSA inspection requirements, Changes of international standards (IAEA, ISO?), Conclusions of first PSR, Implementation of ISO standards in Krsko NPP (ISO14001, ISO17025), Changes of plant procedures, etc. One of the most obvious changes was the enlargement of the QA Plan scope to cover interdisciplinary areas defined in the plant management program MD-1, such as Safety culture, Self-assessment, Human performance, Industrial Safety etc. The attachment of the QA Plan defining relationships between certain standards was also updated to provide matrix for better correlation of requirements of

    1978-01-01

    The Nuclear Safety Guide was first issued in 1956 as classified AEC report LA-2063 and was reprinted the next year, unclassified, as TID-7016. Revision 1, published in 1961, extended the scope and refined the guiding information. The present revision of the Guide differs significantly from its predecessor in that the latter was intentionally conservative in its recommendations. Firmly based on experimental evidence of criticality, the original Guide and the first revision were considered to be of most value to organizations whose activities with fissionable materials were not extensive and, secondarily, that it would serve as a point of departure for members of established nuclear safety teams, experienced in the field. The reader will find a significant change in the character of information presented in this version. Nuclear Criticality Safety has matured in the past twelve years. The advance of calculational capability has permitted validated calculations to extend and substitute for experimental data. The broadened data base has enabled better interpolation, extension, and understanding of available information, especially in areas previously addressed by undefined but adequate factors of safety. The content has been thereby enriched in qualitative guidance. The information inherently contains, and the user can recapture, the quantitative guidance characteristic of the formerGuides by employing appropriate safety factors.

    Revised MIXSET is a FORTRAN IV calculation code developed to simulate steady and transient behaviors of the Purex extraction process and calculate the optimum operating condition of the process. Revised MIXSET includes all the functions of MIXSET code as shown below. a) Maximum chemical system of eight components can be handled with or without mutual dependence of the distribution of components. b) The flowrate and concentration of feed can be renewed successively at any state, transient or steady, for searching optimum operating conditions. c) Optimum inputs of feed concentrations and flowrates can be calculated to satisfy both of specification and recovery rate of a product. d) Radioactive decay reactions can be handled on each component. Besides these functions, the following chemical reactions concerned in Purex process are newly-included in Revised MIXSET code and the quantitative changes of components such as H + , U(IV), U(VI), Pu(III), Pu(IV), NH 2 OH, N 2 H 4 can be simulated. 1st Gr.

    A small number of patients fail fundoplication and require reoperation. Laparoscopic techniques have been applied to reoperative fundoplications. We reviewed our experience with reoperative laparoscopic fundoplication. Reoperative laparoscopic fundoplication was undertaken in 28 patients, 19 F and 9 M, of mean age 56 years +/- 12. Previous antireflux procedures included 19 open and 12 laparoscopic antireflux operations. Symptoms were heartburn (90%), dysphagia (35%), and atypical symptoms (30%%). The mean interval from antireflux procedure to revision was 13 months +/- 4.2. The mean DeMeester score was 78+/-32 (normal 14.7). Eighteen patients (64%) had hiatal breakdown, 17 (60%) had wrap failure, 2 (7%) had slipped Nissen, 3 (11%) had paraesophageal hernias, and 1 (3%) had an excessively tight wrap. Twenty-five revisions were completed laparoscopically, while 3 patients required conversion to the open technique. Complications occurred in 9 of 17 (53%) patients failing previous open fundoplications and in 4 of 12 patients (33%) failing previous laparoscopic fundoplications and included 15 gastrotomies and 1 esophagotomy, all repaired laparoscopically, 3 postoperative gastric leaks, and 4 pneumothoraces requiring tube thoracostomy. No deaths occurred. Median length of stay was 5 days (range 2-90 days). At a mean follow-up of 20 months +/- 17, 2 patients (7%) have failed revision of their fundoplications, with the rest of the patients being essentially asymptomatic (93%). The results achieved with reoperative laparoscopic fundoplication are similar to those of primary laparoscopic fundoplications. Laparoscopic reoperations, particularly of primary open fundoplication, can be technically challenging and fraught with complications. Copyright 2001 Academic Press.

  14. Nuclear safety guide. TID-7016, Revision 2

    Energy Technology Data Exchange (ETDEWEB)

    Thomas, J T [ed.

    1978-05-01

    The Nuclear Safety Guide was first issued in 1956 as classified AEC report LA-2063 and was reprinted the next year, unclassified, as TID-7016. Revision 1, published in 1961, extended the scope and refined the guiding information. The present revision of the Guide differs significantly from its predecessor in that the latter was intentionally conservative in its recommendations. Firmly based on experimental evidence of criticality, the original Guide and the first revision were considered to be of most value to organizations whose activities with fissionable materials were not extensive and, secondarily, that it would serve as a point of departure for members of established nuclear safety teams, experienced in the field. The reader will find a significant change in the character of information presented in this version. Nuclear Criticality Safety has matured in the past twelve years. The advance of calculational capability has permitted validated calculations to extend and substitute for experimental data. The broadened data base has enabled better interpolation, extension, and understanding of available information, especially in areas previously addressed by undefined but adequate factors of safety. The content has been thereby enriched in qualitative guidance. The information inherently contains, and the user can recapture, the quantitative guidance characteristic of the formerGuides by employing appropriate safety factors. In fact, it becomes incumbent on the Criticality Safety Specialist to necessarily impose safety factors consistent with the possible normal and abnormal credible contingencies of an operation as revealed by his evaluation. In its present form the Guide easily becomes a suitable module in any compendium or handbook tailored for internal use by organizations. It is hoped the Guide will continue to serve immediate needs and will encourage continuing and more comprehensive efforts toward organizing nuclear criticality safety information.

  15. Closed cooling water chemistry guidelines revision

    McElrath, Joel; Breckenridge, Richard

    2014-01-01

    This second revision of the Closed Cooling Water Chemistry Guideline addresses the use of chemicals and monitoring methods to mitigate corrosion, fouling, and microbiological growth in the closed cooling-water (CCW) systems of nuclear and fossil-fueled power plants. This revision has been endorsed by the utility chemistry community and represents another step in developing a more proactive chemistry program to limit or control closed cooling system degradation with increased consideration of corporate resources and plant-specific design and operating concerns. These guidelines were developed using laboratory data, operating experience, and input from organizations and utilities within and outside of the United States of America. It is the intent of the Revision Committee that these guidelines are applicable to all nuclear and fossil-fueled generating stations around the world. A committee of industry experts—including utility specialists, Institute of Nuclear Power Operations representatives, water-treatment service-company representatives, consultants, a primary contractor, and EPRI staff—collaborated in reviewing available data on closed cooling-water system corrosion and microbiological issues. Recognizing that each plant owner has a unique set of design, operating, and corporate concerns, the Guidelines Committee developed a methodology for plant-specific optimization. The guideline provides the technical basis for a reasonable but conservative set of chemical treatment and monitoring programs. The use of operating ranges for the various treatment chemicals discussed in this guideline will allow a power plant to limit corrosion, fouling, and microbiological growth in CCW systems to acceptable levels. The guideline now includes closed cooling chemistry regimes proven successful in use in the international community. The guideline provides chemistry constraints for the use of phosphates control, as well as pure water with pH control. (author)

    The article deals with a guideline, compiled by the IAEA, for radiation protection. The guidelines aim at the control of individual risk through specified limits, optimisation of protection and the justification of all practices involving exposure to radiation. The guideline is a revision of the 1967 publication of the IAEA, Basic safety standards for radiation protection. According to the document the main resposibility for radiation protection lies with the employer. The workers should be responsible for observing protection procedures and regulations for their own as well as others' safety

    During the operation of nuclear power plants it is normally possible for the in-house personnel to take care of arising radiation protection problems. However, in the comparatively short revision phases, the duties of radiation protection become much more varied. Additional trained radiation protection crews are needed at short notice. This is also the time in which the largest contributions are made to the annual cumulated doses of the personnel. Recent guidelines and rules trying to reduce the radiation exposure of personnel concentrate on this very point. The article outlines the radiation protection activities performed by the service personnel in the course of a steam generator check. (orig.) [de

O experimento foi conduzido no pomar experimental de mirtileiro, da Embrapa Clima Temperado em Pelotas, RS. Foram marcadas 200 flores de mirtileiro, seleção 103, sendo 100 destas com dano feito pela irapuá e 100 sem o dano. Após a floração, foi observada a frutificação efetiva, e por ocasião da colheita, foram determinados o teor de sólidos solúveis totais (SST, o diâmetro dos frutos e o número de sementes por fruto. O delineamento experimental foi o inteiramente casualizado. Nas flores sem danos da irapuá, houve maior percentagem de frutificação efetiva, e as frutas oriundas das mesmas apresentaram maior diâmetro e maior quantidade de sementes. O teor de SST nas frutas de mirtilo, oriundas tanto das flores com dano como daquelas sem dano, foi semelhante. Esses resultados sugerem que a T. spinipes é prejudicial à cultura do mirtilo, principalmente na época de floração, pois os danos causados pelo inseto provocaram baixa frutificação, frutas de tamanho reduzido e com menor quantidade de sementes.The irapuá Trigona spinipes is considered a pest insect of several crops because it feeds on their leaves, flowers and fruits.

    Full Text Available Surgery is indicated for symptomatic knee osteoarthritis (OA when conservative measures are unsuccessful. High tibial osteotomy (HTO, unicompartmental knee arthroplasty (UKA, and total knee arthroplasty (TKA are surgical options intended to relieve knee OA pain and dysfunction. The choice of surgical intervention is dependent on several factors such as disease location, patient age, comorbidities, and activity levels. Regardless of surgical treatment, complications such as infection, loosening or lysis, periprosthetic fracture, and postoperative pain are known risks and are indications for revision surgery. The clinical and economic implications for revision surgery are underappreciated. Over 55,000 revision surgeries were performed in 2010 in the US, with 48% of these revisions in patients under 65 years. Total costs associated with each revision TKA surgery have been estimated to be in excess of $49,000. The current annual economic burden of revision knee OA surgery is $2.7 billion for hospital charges alone. By 2030, assuming a 5-fold increase in the number of revision procedures, this economic burden will exceed $13 billion annually. It is appealing to envision a therapy that could delay or obviate the need for arthroplasty. From an actuarial standpoint, this would have the theoretical downstream effect of substantially reducing the number of revision procedures. Although no known therapies currently meet these criteria, such a breakthrough would have a tremendous impact in lessening the clinical and economic burden of knee OA revision surgery.

    There remains a paucity of studies examining the conversion of failed hemiarthroplasty (HA) to reverse total shoulder arthroplasty (RTSA). Therefore, the purpose of this study was to examine a large series of revision HA to RTSA. A population of 157 patients who underwent conversion of a failed HA to a revision RTSA from 2006 through 2014 were included. The mean follow-up was 49 months (range, 24-121 months). The indications for revision surgery included instability with rotator cuff insufficiency (n = 127) and glenoid wear (n = 30); instability and glenoid wear were associated in 38 cases. Eight patients with infection underwent 2-stage reimplantation. Patients experienced significant improvements in their preoperative to postoperative pain and shoulder range of motion (P surgeries, secondary to glenoid component loosening (n = 3), instability (n = 3), humeral component disassembly (n = 2), humeral stem loosening (n = 1), and infection (n = 2). Implant survivorship was 95.5% at 2 years and 93.3% at 5 years. There were 4 reoperations including axillary nerve neurolysis (n = 2), heterotopic ossification removal (n = 1), and hardware removal for rupture of the metal cerclage for an acromial fracture (n = 1). At final follow-up, there were 5 "at-risk" glenoid components. Patients experience satisfactory pain relief and recovery of reasonable shoulder function after revision RTSA from a failed HA. There was a relatively low revision rate, with glenoid loosening and instability being the most common causes. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

    We carry out a comprehensive study of H I 21 cm line observations and 13CO line observations of 21 supernova remnants (SNRs). The aim of the study is to search for H I absorption features to obtain kinematic distances in a consistent manner. The 21 SNRs are in the region of sky covered by the Very Large Array Galactic Plane Survey (H I 21 cm observations) and Galactic Ring Survey (13CO line observations). We obtain revised distances for 10 SNRs based on new evidence in the H I and 13CO observations. We revise distances for the other 11 SNRs based on an updated rotation curve and new error analysis. The mean change in distance for the 21 SNRs is ≃25%, i.e., a change of 1.5 kpc compared to a mean distance for the sample of 6.4 kpc. This has a significant impact on interpretation of the physical state of these SNRs. For example, using a Sedov model, age and explosion energy scale as the square of distance, and inferred ISM density scales as distance.

  13. Three Principles to REVISE People's Unethical Behavior.

    Science.gov (United States)

    2015-11-01

    Dishonesty and unethical behavior are widespread in the public and private sectors and cause immense annual losses. For instance, estimates of U.S. annual losses indicate $1 trillion paid in bribes, $270 billion lost due to unreported income, and $42 billion lost in retail due to shoplifting and employee theft. In this article, we draw on insights from the growing fields of moral psychology and behavioral ethics to present a three-principle framework we call REVISE. This framework classifies forces that affect dishonesty into three main categories and then redirects those forces to encourage moral behavior. The first principle, reminding, emphasizes the effectiveness of subtle cues that increase the salience of morality and decrease people's ability to justify dishonesty. The second principle, visibility, aims to restrict anonymity, prompt peer monitoring, and elicit responsible norms. The third principle, self-engagement, increases people's motivation to maintain a positive self-perception as a moral person and helps bridge the gap between moral values and actual behavior. The REVISE framework can guide the design of policy interventions to defeat dishonesty. © The Author(s) 2015.

  14. A Way to Revised Quantum Electrodynamics

    Directory of Open Access Journals (Sweden)

    Lehnert B.

    2012-04-01

    Full Text Available In conventional theoretical physics and its Standard Model the guiding principle is that the equations are symmetrical. This limitation leads to a number of difficulties, because it does not permit masses for leptons and quarks, the electron tends to “explode” un- der the action of its self-charge, a corresponding photon model has no spin, and such a model cannot account for the “needle radiation” proposed by Einstein and observed in the photoelectric e ff ect and in two-slit experiments. This paper summarizes a revised Lorentz and gauge invariant quantum electrodynamic theory based on a nonzero electric field divergence in the vacuum and characterized by linear intrinsic broken symmetry. It thus provides an alternative to the Higgs concept of nonlinear spontaneous broken sym- metry, for solving the difficulties of the Standard Model. New results are obtained, such as nonzero and finite lepton rest masses, a point-charge-like behavior of the electron due to a revised renormalization procedure, a magnetic volume force which counteracts the electrostatic eigen-force of the electron, a nonzero spin of the photon and of light beams, needle radiation, and an improved understanding of the photoelectric effect, two-slit ex- periments, electron-positron pair formation, and cork-screw-shaped light beams.

  15. REVISED STREAM CODE AND WASP5 BENCHMARK

    International Nuclear Information System (INIS)

    Chen, K

    2005-01-01

    STREAM is an emergency response code that predicts downstream pollutant concentrations for releases from the SRS area to the Savannah River. The STREAM code uses an algebraic equation to approximate the solution of the one dimensional advective transport differential equation. This approach generates spurious oscillations in the concentration profile when modeling long duration releases. To improve the capability of the STREAM code to model long-term releases, its calculation module was replaced by the WASP5 code. WASP5 is a US EPA water quality analysis program that simulates one-dimensional pollutant transport through surface water. Test cases were performed to compare the revised version of STREAM with the existing version. For continuous releases, results predicted by the revised STREAM code agree with physical expectations. The WASP5 code was benchmarked with the US EPA 1990 and 1991 dye tracer studies, in which the transport of the dye was measured from its release at the New Savannah Bluff Lock and Dam downstream to Savannah. The peak concentrations predicted by the WASP5 agreed with the measurements within ±20.0%. The transport times of the dye concentration peak predicted by the WASP5 agreed with the measurements within ±3.6%. These benchmarking results demonstrate that STREAM should be capable of accurately modeling releases from SRS outfalls

  16. Scar modification. Techniques for revision and camouflage.

    1998-09-01

    The surgery and management of scars is a protracted and staged process that includes preparation of the skin through hygienic measures, scar softening (if indicated) with steroids, massage and pressure dressings, skilled execution of the surgical plan, and thorough postoperative wound care. This process generally covers a 1-year period for the various stages mentioned. Many general host and local skin factors will directly affect the final revision result. The two most important indirect factors that the surgeon must endeavor to control are optimal patient preparation and cutaneous health, and patient compliance with, and an ability to carry out, those wound care measures that the surgeon prescribes. Keloid and burn contracture scars represent two entities that are complicated and challenging to treat owing to their abnormal morphophysiologic features. Management of these scars is prolonged, and the patient must understand that the ultimate result will usually be a compromise. New grafting techniques, such as cultured autodermal grafts, offer improved initial management of burn wounds that may subsequently optimize scar revision in these patients. Keloids, and to a lesser extent hypertrophic scars, require steroid injections, pressure treatment, careful surgery, and protracted wound support and pressure treatment (exceeding 6 months) after surgery.

    Based on the experimental wavenumbers of 344 spectral lines from calibrated Fourier transform (FT) spectra as well as wavenumbers of 81 lines from the wavelength tables from literature, the energy of 115 fine structure levels of singly ionized lanthanum has been revised by weighted global fits. The classifications of the lines are provided by numerous previous investigations of lanthanum by different spectroscopic methods and authors. For the high accurate determination of the center of gravity wavenumbers from the experimental spectrum, the hyperfine constants of the involved levels have been taken into account, if possible. For the 94 levels with known hyperfine constants the accuracy of energy values is better than 0.01 cm-1. For 34 levels the magnetic dipole hyperfine constants A have been determined from FT spectra as part of this work. For four of these 34 levels even electric quadrupole hyperfine constants B could be estimated. For levels, which have experimentally unknown hyperfine constants and which are connected only by lines not found in the FT spectra but taken from literature, the uncertainties of energy values are about a factor of 10 higher. A list of all revised level energies together with a compilation of hyperfine structure data is given as well as a list of all lines used.

  18. [Revision of the drinking water regulations].

    The revision the Drinking Water Regulations will come into effect on 01.11.2011. Surveillance authorities and owners of drinking water supply systems had hoped for simplifications and reductions because of the new arrangements. According to the official statement for the revision the legislature intended to create more clarity, consider new scientific findings, to change regulations that have not been proved to close regulatory gaps, to deregulate and to increase the high quality standards. A detailed examination of the regulation text, however, raises doubts. The new classification of water supply systems requires different modalities of registration, water analyses and official observation, which will complicate the work of the authorities. In particular, the implementation of requirements of registration and examination for the owners of commercial and publicly-operated large hot-water systems in accordance with DVGW Worksheet W 551 requires more effort. According to the estimated 30 000 cases of legionellosis in Germany the need for a check of such systems for Legionella, however, is not called into question. Furthermore, the development of sampling plans and the monitoring of mobile water supply systems requires more work for the health authorities. © Georg Thieme Verlag KG Stuttgart · New York.

    Effective utilisation of blood products is fundamental. The introduction of maximum surgical blood ordering schedules (MSBOS) for operations has been shown to improve transfusion services. A retrospective analysis was undertaken to establish an evidence-based MSBOS for revision total hip replacement (THR) and total knee revision (TKR). The impact of this schedule on blood conservation was analysed. A retrospective analysis was undertaken on 397 patients who underwent revision THR and TKR over a 4-year period. The cross-match-to-transfusion ratio (CTR) and transfusion index (TI) were calculated. A MSBOS protocol was created based on the TIs and its' impact on transfusion services was assessed prospectively on 125 patients by comparing CTRs. In revision THR, TI was 1.19 for elective cases, 1.55 for emergency cases and 2.35 for infected cases. There was no difference in TI for revisions of cemented and uncemented components. Single component THR revision required less transfusion. In revision TKR, TI was 0.31 for elective cases, 2.0 for emergency cases and 1.23 for cases with infection. The introduction of the MSBOS protocol had resulted in a considerable improvement in blood ordering. Reductions in the CTR were seen for all types of revision surgery, but most evident in elective revision THR (3.24-2.18) and elective revision TKR (7.95-1.2). Analysis confirmed that excessive cross-matching occurred for revision lower limb arthroplasty. The introduction of our MSBOS protocol promoted blood conservation and compliance with established national guidelines.

    Revision anterior cruciate ligament (ACL) reconstruction has worse outcomes than primary reconstructions. Predictors for these worse outcomes are not known. The Multicenter ACL Revision Study (MARS) Group was developed to perform a multisurgeon, multicenter prospective longitudinal study to obtain sufficient subjects to allow multivariable analysis to determine predictors of clinical outcome. To describe the formation of MARS and provide descriptive analysis of patient demographics and clinical features for the initial 460 enrolled patients to date in this prospective cohort. Cross-sectional study; Level of evidence, 2. After training and institutional review board approval, surgeons began enrolling patients undergoing revision ACL reconstruction, recording patient demographics, previous ACL reconstruction methods, intra-articular injuries, and current revision techniques. Enrolled subjects completed a questionnaire consisting of validated patient-based outcome measures. As of April 1, 2009, 87 surgeons have enrolled a total of 460 patients (57% men; median age, 26 years). For 89%, the reconstruction was the first revision. Mode of failure as deemed by the revising surgeon was traumatic (32%), technical (24%), biologic (7%), combination (37%), infection (MARS Group has been able to quickly accumulate the largest revision ACL reconstruction cohort reported to date. Traumatic reinjury is deemed by surgeons to be the most common single mode of failure, but a combination of factors represents the most common mode of failure. Allograft graft choice is more common in the revision setting than autograft. Concomitant knee injury is extremely common in this population.

    2015-04-01

    Full Text Available The revision as an extraordinary legal remedy is one more legal instrument for litigant in the effort to achieve protection of the rights or to defend against ungrounded claims of the other party. Litigants may declare revision of the litigation process due to substantive violations of the provisions of Civil Procedure and incorrect application of substantive law. Declaring revision because of a substantive violation of the provisions of Civil Procedure is limited. The purpose of this research paper is to investigate the most common reasons for filing revision of the litigation process in the period from June 2011 to June in 2012. The research includes what kind of reasons are often repeated, and the volume, or the number of reviews submitted to the Supreme Court of the Republic of Macedonia. As general hypothesis is that most of the adopted revisions are due to substantial violations of the provisions of civil procedure. Two-thirds of the stated revisions in front of the Supreme Court of Republic of Macedonia were rejected as unfounded and only one third of the submitted revisions from June 2011 to June 2012 were grounded. Since accepted revisions 59% due to incorrect application of substantive law, and 41% due to substantial violations of the provisions of Civil Procedure.

    Pérez, Ana; Cain, Kate; Castellanos, María C; Bajo, Teresa

    2015-11-01

    We evaluated the process of inferential revision during text comprehension in adults. Participants with high or low working memory read short texts, in which the introduction supported two plausible concepts (e.g., 'guitar/violin'), although one was more probable ('guitar'). There were three possible continuations: a neutral sentence, which did not refer back to either concept; a no-revise sentence, which referred to a general property consistent with either concept (e.g., '…beautiful curved body'); and a revise sentence, which referred to a property that was consistent with only the less likely concept (e.g., '…matching bow'). Readers took longer to read the sentence in the revise condition, indicating that they were able to evaluate their comprehension and detect a mismatch. In a final sentence, a target noun referred to the alternative concept supported in the revise condition (e.g., 'violin'). ERPs indicated that both working memory groups were able to evaluate their comprehension of the text (P3a), but only high working memory readers were able to revise their initial incorrect interpretation (P3b) and integrate the new information (N400) when reading the revise sentence. Low working memory readers had difficulties inhibiting the no-longer-relevant interpretation and thus failed to revise their situation model, and they experienced problems integrating semantically related information into an accurate memory representation.

    von Roth, Philipp; Wassilew, Georgi I

    2017-10-01

    Extra-large uncemented jumbo cups are among the most common methods of acetabular revision. Jumbo cups do not contribute to bone stock restoration, and in the case of a subsequent revision, an even larger bone defect is to be expected. Thus, understanding long-term survival is essential. The present article discusses the literature relevant to this topic and addresses technical and implant-specific characteristics of jumbo cups. In summary, jumbo cups show an acceptable long-term survival rate, with aseptic loosening as the most common reason for revision and dislocation being the most common complication. Through the development of alternative revision systems, jumbo cups have lost their importance in today's practice. However, they can serve as a benchmark for studies of newer technologies in revision total hip arthroplasty. Georg Thieme Verlag KG Stuttgart · New York.

A total of 35,960 THAs registered from 4/2001-12/2010 were evaluated. The 8-year survival rate was 96.7% (95% CI 96.4%-97.0%). Females had a higher risk of aseptic revision than males. Hispanic and Asian patients had a lower risk of revision than white patients. Ceramic-on-ceramic, ceramic-on-conventional polyethylene, and metal-on-conventional polyethylene bearing surfaces had a higher risk of revision than metal-on-highly cross-linked polyethylene. Body mass index, health status, diabetes, diagnosis, fixation, approach, bilateral procedures, head size, surgeon fellowship training, surgeon and hospital volume were not revision risk factors.

Os frutos foram resfriados num sistema de circulação com ar forçado (1.933m³/h, à temperatura de 1°C e 7°C, umidade relativa de 88,4 ± 2,0% e velocidade do ar em torno de 1m/s. Um modelo matemático bidimensional, em coordenadas esferoidais prolato, foi aplicado para predizer a condução de calor transiente dentro das frutas, assumindo-se condição de contorno convectiva na superfície do corpo. As equações geradas foram resolvidas numericamente pelo método de volumes finitos e o coeficiente convectivo de transferência de calor foi obtido aplicando o método de ajuste do erro quadrático mínimo, entre os dados experimentais e numéricos. A análise comparativa das curvas teóricas e experimentais mostrou uma concordância satisfatória, com valores de erro entre 5% e 7%. Notou-se que o coeficiente de transferência de calor varia com a posição dos frutos no leito e que o tempo de resfriamento apresenta uma variação de aproximadamente 38% entre os diferentes pontos. A distribuição espacial de temperatura no interior dos frutos, para três instantes de tempo, demonstrou a existência de um diferencial de temperatura entre o centro e a superfície de aproximadamente 30%. O modelo matemático prediz que a taxa de resfriamento nas bananas é muito mais alta nas pontas que nas outras regiões do fruto.

    Bulkeley, Kelly

    2014-10-01

    This article demonstrates the use of a digital word search method designed to provide greater accuracy, objectivity, and speed in the study of dreams. A revised template of 40 word search categories, built into the website of the Sleep and Dream Database (SDDb), is applied to four "classic" sets of dreams: The male and female "Norm" dreams of Hall and Van de Castle (1966), the "Engine Man" dreams discussed by Hobson (1988), and the "Barb Sanders Baseline 250" dreams examined by Domhoff (2003). A word search analysis of these original dream reports shows that a digital approach can accurately identify many of the same distinctive patterns of content found by previous investigators using much more laborious and time-consuming methods. The results of this study emphasize the compatibility of word search technologies with traditional approaches to dream content analysis. Copyright © 2014 Elsevier Inc. All rights reserved.

  9. A revision of the generalized uncertainty principle

    International Nuclear Information System (INIS)

    Bambi, Cosimo

    2008-01-01

    The generalized uncertainty principle arises from the Heisenberg uncertainty principle when gravity is taken into account, so the leading order correction to the standard formula is expected to be proportional to the gravitational constant G N = L 2 Pl . On the other hand, the emerging picture suggests a set of departures from the standard theory which demand a revision of all the arguments used to deduce heuristically the new rule. In particular, one can now argue that the leading order correction to the Heisenberg uncertainty principle is proportional to the first power of the Planck length L Pl . If so, the departures from ordinary quantum mechanics would be much less suppressed than what is commonly thought

    In the field of radiation protection, the Commission of the European Communities possesses certain powers which allowed it to develop a common health policy and to promote the harmonization of regulations on protecting the health of workers and the population from ionizing radiations. The Community directives constitute the legal instrument which enabled the policy to be achieved; the principles are based on the recommendations of the ICRP but are adapted to the requirements of the Euratom Treaty. The revision of the standards gave the experts and the Commission the opportunity to examine in detail a certain number of new concepts recently introduced in the international recommendations and to update and improve the standards laid down for the first time in 1959.

  17. Revised models of interstellar nitrogen isotopic fractionation

    Science.gov (United States)

    Wirström, E. S.; Charnley, S. B.

    2018-03-01

    Nitrogen-bearing molecules in cold molecular clouds exhibit a range of isotopic fractionation ratios and these molecules may be the precursors of 15N enrichments found in comets and meteorites. Chemical model calculations indicate that atom-molecular ion and ion-molecule reactions could account for most of the fractionation patterns observed. However, recent quantum-chemical computations demonstrate that several of the key processes are unlikely to occur in dense clouds. Related model calculations of dense cloud chemistry show that the revised 15N enrichments fail to match observed values. We have investigated the effects of these reaction rate modifications on the chemical model of Wirström et al. (2012) for which there are significant physical and chemical differences with respect to other models. We have included 15N fractionation of CN in neutral-neutral reactions and also updated rate coefficients for key reactions in the nitrogen chemistry. We find that the revised fractionation rates have the effect of suppressing 15N enrichment in ammonia at all times, while the depletion is even more pronounced, reaching 14N/15N ratios of >2000. Taking the updated nitrogen chemistry into account, no significant enrichment occurs in HCN or HNC, contrary to observational evidence in dark clouds and comets, although the 14N/15N ratio can still be below 100 in CN itself. However, such low CN abundances are predicted that the updated model falls short of explaining the bulk 15N enhancements observed in primitive materials. It is clear that alternative fractionating reactions are necessary to reproduce observations, so further laboratory and theoretical studies are urgently needed.

  18. Revised spatially distributed global livestock emissions

    2015-12-01

    Livestock play an important role in agricultural carbon cycling through consumption of biomass and emissions of methane. Quantification and spatial distribution of methane and carbon dioxide produced by livestock is needed to develop bottom-up estimates for carbon monitoring. These estimates serve as stand-alone international emissions estimates, as input to global emissions modeling, and as comparisons or constraints to flux estimates from atmospheric inversion models. Recent results for the US suggest that the 2006 IPCC default coefficients may underestimate livestock methane emissions. In this project, revised coefficients were calculated for cattle and swine in all global regions, based on reported changes in body mass, quality and quantity of feed, milk production, and management of living animals and manure for these regions. New estimates of livestock methane and carbon dioxide emissions were calculated using the revised coefficients and global livestock population data. Spatial distribution of population data and associated fluxes was conducted using the MODIS Land Cover Type 5, version 5.1 (i.e. MCD12Q1 data product), and a previously published downscaling algorithm for reconciling inventory and satellite-based land cover data at 0.05 degree resolution. Preliminary results for 2013 indicate greater emissions than those calculated using the IPCC 2006 coefficients. Global total enteric fermentation methane increased by 6%, while manure management methane increased by 38%, with variation among species and regions resulting in improved spatial distributions of livestock emissions. These new estimates of total livestock methane are comparable to other recently reported studies for the entire US and the State of California. These new regional/global estimates will improve the ability to reconcile top-down and bottom-up estimates of methane production as well as provide updated global estimates for use in development and evaluation of Earth system models.

  19. CUSTOMIZED ACETABULAR COMPONENTS IN REVISION HIP ARTHROPLASTY

    2016-01-01

    Full Text Available In recent years, there is a trend of increasing demand for revision hip arthroplasty. Among these patients there are many with complex acetabular defects, including patients with pelvic discontinuity. To ensure stability for revised acetabular components in such cases becomes a challenging or unachievable task. Such defects give indications for printing customized tri-flange acetabular component. The authors analysed own experience of creating and applying custom made acetabular components in 3 patients with complex acetabular defects. Material and methods. Among the patients there were 2 women and 1 man. Average age was 60,3±19,4 years (38 to 78 years. Two patients had III B defects with pelvic discontinuity and one patient had III A defect by Paprosky classification. As the first step, the authors in collaboration with engineers printed a plaster full size pelvic 3D model, as the second step a customized tri-flange acetabular component was designed and printed. Harris Hip Score was evaluated preoperatively and 3 months postoperatively. Results. Average follow-up period was 5,3±2,5 months (3 to 8 months. The authors observed no cases of implant loosening, dislocation or deep periprosthetic infection. Average Harris Hip Score before surgery was 27,13 and after surgery – 74,1 indicating a significant improvement in 3 months postoperatively. Conclusion. Indications for use of individual acetabular components in reported patients correspond to indications formulated by Berasi et al. The authors obtained encouraging early follow-up outcomes that correspond to data of other authors. In one patient certain difficulties were reported due to insufficient pelvic distraction. Component’s flanges prevented achieving adequate pelvic distraction. Nevertheless, good primary stability was achieved. Modern software and 3D metal printers can significantly reduce the production cost of customized acetabular components. Application of this technology can be

  20. Nuclear safety guide TID-7016 Revision 2

    International Nuclear Information System (INIS)

    Thomas, J.T.

    1980-01-01

    The present revision of TID-7016 Nuclear Safety Guide is discussed. This Guide differs significantly from its predecessor in that the latter was intentionally conservative in its recommendations. Firmly based on experimental evidence of criticality, the original Guide and the first revision were considered to be of most value to organizations whose activities with fissionable materials were not extensive and, secondarily, that it would serve as a point of departure for members of established nuclear safety teams, experienced in the field. The reader will find a significant change in the character of information presented in this version. Nuclear Criticality Safety has matured in the past twelve years. The advance of calculational capability has permitted validated calculations to extend and substitute for experimental data. The broadened data base has enabled better interpolation, extension, and understanding of available, information, especially in areas previously addressed by undefined but adequate factors of safety. The content has been thereby enriched in qualitative guidance. The information inherently contains, and the user can recapture, the quantitative guidance characteristic of the former Guides by employing appropriate safety factors. In fact, it becomes incumbent on the Criticality Safety Specialist to necessarily impose safety factors consistent with the possible normal and abnormal credible contingencies of an operation as revealed by his evaluation. In its present form the Guide easily becomes a suitable module in any compendium or handbook tailored for internal use by organizations. It is hoped the Guide will continue to serve immediate needs and will encourage continuing and more comprehensive efforts toward organizing nuclear criticality safety information

    Adamson, M. G.

    1997-01-01

    The re-baseline of the Expedited Technology Demonstration Project (Revised Mixed Waste Facility Project) is designated as Project Baseline Revision 4.0. The last approved baseline was identified as Project Baseline Revision 3.0 and was issued in October 1996. Project Baseline Revision 4.0 does not depart from the formal DOE guidance followed by, and contained in, Revision 3.0. This revised baseline document describes the MSO and Final Forms testing activities that will occur during FY98, the final year of the ETD Project. The cost estimate for work during FY98 continues to be $2.OM as published in Revision 3.0. However, the funds will be all CENRTC rather than the OPEX/CENTRC split previously anticipated. LLNL has waived overhead charges on ETD Project CENRTC funds since the beginning of project activities. By requesting the $2.OM as all CENTRC a more aggressive approach to staffing and testing can be taken. Due to a cost under- run condition during FY97 procurements were made and work was accomplished, with the knowledge of DOE, in the Feed Preparation and Final Forms areas that were not in the scope of Revision 3.0. Feed preparation activities for FY98 have been expanded to include the drum opening station/enclosure previously deleted

    Subsidence is one of the potential complications in femoral stem revision total hip arthroplasty surgery, and can affect stability and osseointegration. A retrospective study was conducted on the outcomes at one year and 5 years (specifically subsidence and clinical relevance) of 40 consecutive femoral total hip arthroplasty revisions, comparing two modular cementless revision stems, Straight vs. Curved, with 20 patients in each group. No mechanical failure was observed, and there was an improvement in functional outcomes. Mean radiological subsidence was 9.9±4.9mm (straight=10.75mm vs. curved=9.03mm), with no statistically significant difference between groups (p=0,076). Fourteen patients (35%) had ≥10mm of subsidence, up to a maximum of 22mm. The subsidence found in this study is similar to published series, with no short-term clinical manifestations, or an increased number of complications or stem loosening in either the Straight or Curved group. No differences in subsidence were observed at one year and 5 years after surgery between the 2 types of stems. Copyright © 2017 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.

    2012-01-01

    Full Text Available Background: The aim of this study was to review the management of ventriculoperitoneal (VP shunt complications in children. Patients and Methods: During the last 5 years (January 1, 2006 to December 31, 2010, 236 VP shunt operations were performed in children under 12 years of age; of these, 40 (16.94% developed shunt complications and those who underwent VP shunt revisions were studied. Results: This prospective study included 40 (28 boys and 12 girls children and required 48 shunt revisions. Complications following VP shunts that required shunt revisions were peritoneal catheter/peritoneal end malfunction (18, shunt/shunt tract infections (7, extrusion of peritoneal catheter through anus (5, ventricular catheter malfunction (4, cerebrospinal fluid (CSF leak from abdominal wound (4, shunt system failure (2, ventricular end/shunt displacement (2, CSF pseudocysts peritoneal cavity (2, extrusion of peritoneal catheter from neck, chest, abdominal scar and through umbilicus, one each. Four-fifth of these shunt complications occurred within 6 months of previous surgery. Surgical procedures done during shunt revisions in order of frequency were revision of peritoneal part of shunt (27, 56.25%, revision of entire shunt system (6, 12.5%, extra ventricular drainage and delayed re-shunt (5, 10.41%, shunt removal and delayed re-shunt (5, 10.41%, opposite side shunting (2, 4.16%, cysts excision and revision of peritoneal catheter (2, 4.16% and revision of ventricular catheter (1, 2.08%. The mortalities following VP shunt operations were 44 (18.64% and following shunt revisions were 4 (10%. Conclusions: VP shunt done for hydrocephalus in children is not only prone for complications and need for revision surgery but also associated with considerable mortality.

    Full Text Available O polvilho da fruta-de-lobo é um produto extraído da polpa da fruta-de-lobo verde (Solanum lycocarpum A. St.-Hil., popularmente utilizado. Pouco se conhece a respeito desse polvilho, mas são atribuídos a ele vários efeitos terapêuticos, dentre eles a redução do colesterol. Este trabalho teve o objetivo de verificar a ação da administração do polvilho da fruta-de-lobo sobre animais hipercolesterolêmico. Utilizou-se 24 ratos Wistar fêmeas distribuídas em delineamento ao acaso, em três grupos contendo 8 animais em cada grupo. Estes grupos foram definidos como: controle normal (CN, controle hipocolesterolêmico (CH e hipocolesterolêmico tratado (HT. O grupo CN recebeu dieta comercial, os grupo CH e HT receberam a dieta comercial enriquecida de colesterol e ácido cólico e o grupo HT recebeu também, 100 mg de polvilho da fruta-lobo, diariamente, por sonda orogástrica. O experimento teve uma duração de 6 semanas onde se avaliou o colesterol total sérico semanalmente, peso dos animais semanalmente e o consumo diário de ração. Ao término do experimento, foram avaliados os seguintes parâmetros: frações séricas de colesterol HDL, LDL+VLDL, peso do fígado, colesterol total hepático, lipídeos totais hepático e lâminas de microscopia foram feitas para avaliação dos hepatócitos. Não houve diferença significativa em relação ao peso corporal dos animais, ao consumo da dieta e nas análises de colesterol total sérico entre os grupos estudados. Avaliando-se a relação VLDL +LDL/HDL, os níveis encontrados no grupo HT foram significativamente menores que o grupo CH. Já em relação ao colesterol hepático, o grupo HT mostrou níveis menores de colesterol que o CH. Observou-se nos lipídeos hepáticos que não houve diferença significativa entre os grupo CH e HT, e no peso do fígado houve diferença significativa entre os grupos avaliados. Em relação à microscopia, os grupos hipercolesterolêmicos apresentaram

A aplicação foi feita em maio, quando as frutas estavam com coloração verde-amarelada, e as coletas para avaliação feitas a cada 30 dias, até o mês de novembro. Foram feitas 7 coletas no total. As variáveis estudadas foram coloração da epiderme, espessura da casca, pH do suco, acidez total titulável (ATT, teor de sólidos solúveis totais (SST, relação SST/ATT, índice tecnológico e rendimento de suco. Os resultados obtidos não permitiram concluir que o ácido giberélico tenha influência sobre as características fisico-químicas do suco, tais como pH, rendimento, SST, AT, Ratio e índice tecnológico. A espessura da casca também não foi influenciada pelo AG3. No entanto, o ácido giberélico reteve a coloração verde da casca, segundo um gradiente no que diz respeito à concentração, no sentido de que ao aumentá-la, manteve por mais tempo a coloração verde das frutas. Este comportamento foi observado em maior ou menor escala, em todos os pHs da solução. O pH=3 da calda de aplicação foi o que reteve por mais tempo a coloração verde nas frutas, indicando assim que o ácido giberélico foi mais absorvido neste pH, do que nos demais. O pH normal (4,5 reteve a coloração verde das frutas por mais tempo que o pH=6, indicando assim que pHs mais ácidos favorecem a absorção do ácido giberélico pelas plantas. Foi observado também que o ácido giberélico atrasou o fenômeno do reverdecimento, o qual ocorre quando as temperaturas se tornam mais altas.The objective of this work was to study the effect of gibberellic acid on "Valência" orange fruits, when applied at various concentrations, under

    To analyze and report the clinical outcomes of a cohort of patients who underwent revision hip preservation with arthroscopy and determine predictors of positive and negative outcomes. During the study period from April 2008 to December 2010, all patients who underwent revision hip preservation with arthroscopy were included. This included patients who had previous open surgery and underwent revision with arthroscopy. Patient-reported outcome (PRO) scores were obtained preoperatively and at 3-month, 1-year, 2-year, and 3-year follow-up time points. Any revision surgeries and conversions to total hip arthroplasty were noted. A multiple regression analysis was performed to look for positive and negative predictive factors for improvement in PROs after revision hip arthroscopy. Forty-seven hips in 43 patients had completed 2 years' follow-up or needed total hip arthroplasty. The mean length of follow-up was 29 months (range, 24 to 47 months). Of the hips, 31 (66%) had either unaddressed or incompletely treated femoroacetabular impingement. There was a significant improvement in all PRO scores at a mean of 29 months after revision (P arthroscopy can achieve moderately successful outcomes and remains a viable treatment strategy after failed primary hip preservation surgery. Preoperative predictors of success after revision hip arthroscopy include segmental labral defects, unaddressed or incompletely addressed femoroacetabular impingement, heterotopic ossification, and previous open surgery.

    It is essential to have a degree of uniformity in the methods used for measuring, evaluating, recording, and reporting data on radioactive material in effluents and solid wastes. For this purpose, the U.S. Nuclear Regulatory Commission (NRC) released a revised version of the Regulatory Guide 1.21 'Measuring, evaluating, and reporting radioactive material in liquid and gaseous effluents and solid waste' (revision 2) in 2009, updating the revision 1 version released in 1974. This study compares the previous revision 1 (1974) version with the revision 2 (2009) version to elaborate on the application of the guidelines to Korea. This study consists of an analysis of the 2009 Revision 2 version of the U.S. NRC Regulatory Guidelines 1.21 and an exposition of methods for its application in the domestic environment. Major revisions were made to allow for the adoption of a risk informed approach. Radionuclides with lower than 1% contribution to emission or radiation levels can be selected as principal radionuclides. Requirements for analysis of leaks and spills have been reinforced, with additional groundwater monitoring and hydrological data analysis becoming necessary.

  10. WASTE CERTIFICATION PROGRAM PLAN - REVISION 7

    International Nuclear Information System (INIS)

    MORGAN, LK

    2002-01-01

    The primary changes that have been made to this revision reflect the relocation of the Waste Certification Official (WCO) organizationally from the Quality Services Division (QSD) into the Laboratory Waste Services (LWS) Organization. Additionally, the responsibilities for program oversight have been differentiated between the QSD and LWS. The intent of this effort is to ensure that those oversight functions, which properly belonged to the WCO, moved with that function; but retain an independent oversight function outside of the LWS Organization ensuring the potential for introduction of organizational bias, regarding programmatic and technical issues, is minimized. The Waste Certification Program (WCP) itself has been modified to allow the waste certification function to be performed by any of the personnel within the LWS Waste Acceptance/Certification functional area. However, a single individual may not perform both the technical waste acceptance review and the final certification review on the same 2109 data package. Those reviews must be performed by separate individuals in a peer review process. There will continue to be a designated WCO who will have lead programmatic responsibility for the WCP and will exercise overall program operational oversite as well as determine the overall requirements of the certification program. The quality assurance organization will perform independent, outside oversight to ensure that any organizational bias does not degrade the integrity of the waste certification process. The core elements of the previous WCP have been retained, however, the terms and process structure have been modified.. There are now two ''control points,'' (1) the data package enters the waste certification process with the signature of the Generator Interface/Generator Interface Equivalent (GI/GIE), (2) the package is ''certified'', thus exiting the process. The WCP contains three steps, (1) the technical review for waste acceptance, (2) a review of the

  11. Insurance Cover for Revised Nuclear Liability

    International Nuclear Information System (INIS)

    Reitsma, S. M. S.

    2008-01-01

    The financial security to be provided to victims of an incident at a nuclear installation is the main objective of international nuclear liability conventions. As from the introduction of the Paris Convention on Third Party Liability in the Field of Nuclear Energy in 1960 and the Vienna Convention on Liability for Nuclear Damage in 1963 insurers have been prepared to provide the financial capacity needed to cover the liability under both conventions. They did so in close co-operation with the competent national and international authorities, which has resulted in the insurability of as much of the nuclear liability under the conventions as possible. This tradition of co-operation between authorities and insurers was extended to include the revision negotiations regarding the above conventions, which were concluded in 1997 and 2004 respectively. This has resulted in the insurability of by far the largest part of the convention based liability. However, some heads of damage have been introduced about which insurers had expressed concerns as to their likelihood to attract insurance support. In view of the explicit choice by Convention States to include the uninsurable heads of damage into the revised conventions one would expect that liability for them would fall upon national Governments. This would reflect practice in a number of States, which already assume liability for uninsurable mandatory liabilities for a long time. Nonetheless some other States now seem reluctant to do so, the resulting deadlock having a tendency to manifest itself in a negative perception of the insurance industry. Insurers are therefore appreciative of the forum provided by the CNS to once again explain the areas where problems as regards insurability have arisen and why this is the case. This presentation will show that those areas are few in number and notably relate to a limited number of environmental damages as well as the extension of prescription periods. Furthermore, thoughts will

    Harris, Paul B; Houston, John M

    2010-06-01

    This study examined the reliability of the Revised Competitiveness Index by investigating the test-retest reliability, interitem reliability, and factor structure of the measure based on a sample of 280 undergraduates (200 women, 80 men) ranging in age from 18 to 28 years (M = 20.1, SD = 2.1). The findings indicate that the Revised Competitiveness Index has high test-retest reliability, high inter-item reliability, and a stable factor structure. The results support the assertion that the Revised Competitiveness Index assesses competitiveness as a stable trait rather than a dynamic state.

    The purpose of this study was to determine failure rates, functional outcomes, and risk factors for failure after revision anterior shoulder stabilization surgery in high-risk adolescent athletes. Adolescent athletes who underwent primary anterior shoulder stabilization were reviewed. Patients undergoing subsequent revision stabilization surgery were identified and analyzed. Failure rates after revision surgery were assessed by Kaplan-Meier analysis. Failure was defined as recurrent instability requiring reoperation. Functional outcomes included the Marx activity score; American Shoulder and Elbow Surgeons score; and University of California, Los Angeles score. The characteristics of patients who required reoperation for recurrent instability after revision surgery were compared with those of patients who required only a single revision to identify potential risk factors for failure. Of 90 patients who underwent primary anterior stabilization surgery, 15 (17%) had failure and underwent revision surgery (mean age, 16.6 years; age range, 14 to 18 years). The mean follow-up period was 5.5 years (range, 2 to 12 years). Of the 15 revision patients, 5 (33%) had recurrent dislocations and required repeat revision stabilization surgery at a mean of 50 months (range, 22 to 102 months) after initial revision. No risk factors for failure were identified. The Kaplan-Meier reoperation-free estimates were 86% (95% confidence interval, 67% to 100%) at 24 months and 78% (95% confidence interval, 56% to 100%) at 48 months after revision surgery. The mean final Marx activity score was 14.8 (range, 5 to 20); American Shoulder and Elbow Surgeons score, 82.1 (range, 33 to 100); and University of California, Los Angeles score, 30.8 (range, 16 to 35). At 5.5 years' follow-up, adolescent athletes had a high failure rate of revision stabilization surgery and modest functional outcomes. We were unable to convincingly identify specific risk factors for failure of revision surgery. Level IV

    Full Text Available O Piauí possui uma área considerável de manga, sendo um grande produtor dessa fruta no Brasil. Contudo, a presença de pragas, como as moscas-das-frutas, tem provocado grandes impactos na cadeia produtiva, pois estes insetos fazem parte de um grupo responsável por grandes prejuízos econômicos na cultura da mangueira. O conhecimento da flutuação populacional e a época de maior ocorrência de uma determinada espécie de inseto de importância econômica são requisitos indispensáveis para o estabelecimento de um controle eficiente e racional. O presente trabalho visou registrar a flutuação populacional das espécies de moscas-das-frutas associadas a variedades de manga, bem como correlacionar a ocorrência das moscas com as médias mensais de temperatura, precipitação e umidade relativa, e também avaliar os atrativos alimentares utilizados na captura dos insetos.

    Full Text Available The French regulation school sets out to carry out an analysis of Capitalism and its transformations, with the purpose of understanding the periods of stable growth and the moments of structural change. The object of this paper consists of carrying out a critical revision of the contributions of this school, concentrating on the conceptual framework that it has developed. For this, in the first place the influences that marked the regulation approach will be reviewed, with special attention on its recovery from the Marxist tradition. Secondly, the ontological and methodological differences between the regulation approach and the neoclassic economy theory will be highlighted. Thirdly, the fundamental concepts of the regulation school will be examined. In fourth place, it will be seen how, from these concepts, the crisis at the beginning of the 1970s was interpreted. In fifth place, how the regulation approach is thought as to the relation between economy and policy. In sixth place, the question of the international dimension will be examined. Finally, the main objections that have been presented to the regulation approach, will be shown and will be evaluated critically.

  17. BWR normal water chemistry guidelines: 1986 revision

    International Nuclear Information System (INIS)

    1988-09-01

    Boiling water reactors (BWRs) have experienced stress corrosion cracking in the reactor cooling system piping resulting in adverse impacts on plant availability and personnel radiation exposure. The BWR Owners Group and EPRI have sponsored a major research and development program to provide remedies for this stress corrosion cracking problem. This work shows that the likelihood of cracking depends on the plant's water chemistry performance (environment) as well as on material condition and stress level. Plant experience and other research demonstrate that water quality also affects fuel performance and radiation field buildup in BWRs. This report,''BWR Normal Water Chemistry Guidelines: 1986 Revision,'' presents suggested generic water chemistry specifications, justifies the proposed water chemistry limits, suggests responses to out-of-specification water chemistry, discusses available chemical analysis methods as well as data management and surveillance schemes, and details the management philosophy required to successfully implement a water chemistry control program. An appendix contains recommendations for water quality of auxiliary systems. 73 refs., 20 figs., 9 tabs

    The Department of Energy currently has over 100 million liters of high-level radioactive waste in storage at the Savannah River Site (SRS). In the late 1970's, the Department of Energy recognized that there were significant safety and cost advantages associated with immobilizing the high-level waste in a stable solid form. Several alternative waste forms were evaluated in terms of product quality and reliability of fabrication. This evaluation led to a decision to build the Defense Waste Processing Facility (DWPF) at SRS to convert the easily dispersed liquid waste to borosilicate glass. In accordance with the NEPA (National Environmental Policy Act) process, an Environmental Impact Statement was prepared for the facility, as well as an Environmental Assessment of the alternative waste forms, and issuance of a Record of Decision (in December, 1982) on the waste form. The Department of Energy, recognizing that start-up of the DWPF would considerably precede licensing of a repository, instituted a Waste Acceptance Process to ensure that these canistered waste forms would be acceptable for eventual disposal at a federal repository. This report is a revision of the DWPF compliance plan

While there are many national and regional definitions, there is no universal legal definition approved by the General Assembly of the United Nations (the one proposed by the Security Council in Res. 1566 (2004 is non-binding, lacking legal authority in international law. The Ad Hoc Committee on Terrorism of the 6th (legal Committee of the General Assembly has, with some interruptions, been trying to reach a legal definition since 1972 - but in vain. In the absence of a legal definition, attempts have been made since the 1980s to reach agreement on an academic consensus definition. The latest outcome is the revised definition reprinted below. It is the result of three rounds of consultations among academics and other professionals. A description how it was arrived at can be found on pp. 39 - 98 of Alex P. Schmid (Ed..

    2006-07-01

    Full Text Available A revised Lorentz invariant electromagnetic theory leading beyond Maxwell's equations, and to a form of extended quantum electrodynamics, has been elaborated on the basis of a nonzero electric charge density and a nonzero electric field divergence in the vacuum state. Among the applications of this theory, there are steady electromagnetic states having no counterpart in conventional theory and resulting in models of electrically charged and neutral leptons, such as the electron and the neutrino. The analysis of the electron model debouches into a point-charge-like geometry with a very small characteristic radius but having finite self-energy. This provides an alternative to the conventional renormalization procedure. In contrast to conventional theory, an integrated radial force balance can further be established in which the electron is prevented from "exploding" under the action of its net self-charge. Through a combination of variational analysis and an investigation of the radial force balance, a value of the electronic charge has been deduced which deviates by only one percent from that obtained in experiments. This deviation requires further investigation. A model of the neutrino finally reproduces some of the basic features, such as a small but nonzero rest mass, an angular momentum but no magnetic moment, and long mean free paths in solid matter.

    The present study evaluated the utility of the Chinese version of the Revised Controlling Behaviors Scale (C-CBS-R) as a measure of controlling behaviors in violent Chinese intimate relationships. Using a mixed-methods approach, in-depth, individual interviews were conducted with 200 Chinese women survivors to elicit qualitative data about their personal experiences of control in intimate relationships. The use of controlling behaviors was also assessed using the C-CBS-R. Interview accounts suggested that the experiences of 91 of the women were consistent with the description of coercive control according to Dutton and Goodman's conceptualization of coercion. Using the split-half validation procedure, a receiver operating characteristics (ROC) curve analysis was conducted with the first half of the sample. The area under the curve (AUC) for using the C-CBS-R to identify high control was .99, and the cutoff score of 1.145 maximized both sensitivity and specificity. Applying the cutoff score to the second half gave a sensitivity of 96% and a specificity of 95%. Overall, the C-CBS-R has demonstrated utility as a measure of controlling behaviors with a cutoff score for distinguishing high from low levels of control in violent Chinese intimate relationships. © The Author(s) 2014.

Neodiplothele can be distinguished from other Sasoninae by the absence of the posterior median spinnerets and differs Neotropical relatives as Cosmopelma by the absence of cuspules on coxae of leg I and Paracenobiopelma by the absence of cuspules on the labium. The male of N. irregularis Mello-Leitão, 1917 and N. picta Vellard, 1924 are described and illustrated for the first time. Neodiplothele leonardosi Mello-Leitão, 1939 is considered a junior synonym of N. irregularis. Five new species are described from Brazil: N. aureus sp. nov. from the states of Ceará, Rio Grande do Norte, Paraíba, and Minas Gerais, N. itabaiana sp. nov. from Sergipe, N. martinsi sp. nov. from Bahia, Espírito Santo, and Minas Gerais, N. indicattii sp. nov. from Espírito Santo, Minas Gerais, Rio de Janeiro, and São Paulo, N. caucaia sp. nov. from Ceará, Goiás, and Mato Grosso do Sul. Two informal groups are proposed based on genitalia morphology: irregularis group and picta group. An identification key and new distribution records for all known species are given.

    Analyses of the 1990 version of the PRISM Advanced Liquid Metal Reactor (ALMR) design are presented and discussed. Most of the calculations were performed using BNL computer codes, particularly SSC and MINET. In many cases, independent BNL calculations were compared against analyses presented by General Electric when they submitted the PRISM design revisions for evaluation by the Nuclear Regulatory Commission (NRC). The current PRISM design utilizes the metallic fuel developed by Argonne National Laboratory (ANL) which facilitates the passive/''inherent'' shutdown mechanism that acts to shut down reactor power production whenever the system overheats. There are a few vulnerabilities in the passive shutdown, with the most worrisome being the positive feedback from sodium density decreases or sodium voiding. Various postulated unscrammed events were examined by GE and/or BNL, and much of the analysis discussed in this report is focused on this category of events. For the most part, the BNL evaluations confirm the information submitted by General Electric. The principal areas of concern are related to the performance of the ternary metal fuel, and may be resolved as ANL continues with its fuel development and testing program

    Full Text Available Pachyptera DC. is a small genus of neotropical lianas included in tribe Bignonieae (Bignoniaceae. The genus has a complicated taxonomic history but currently includes species distributed from Belize to Southern Amazon. Pachyptera is characterised by four main synapomorphies, namely, a papery peeling bark, prophylls of the axillary buds organised in a series of three, patelliform glands arranged in lines in the upper portions of the calyx and corolla tube. Furthermore, members of the genus also have stems with four phloem wedges in cross-section and conspicuous extrafloral nectaries between the interpetiolar region and at the petiole apex, although these characters are also shared with other genera of tribe Bignonieae. Here, we present a taxonomic revision of Pachyptera, which includes a complete list of synonyms, detailed morphological descriptions of species and an identification key, as well as information on the habitat, distribution and phenology, nomenclatural notes, taxonomic comments and illustrations of all the species. In addition, we designate three lectotypes, propose one new combination, raise one variety to species status and describe a new species. After these adjustments, a Pachyptera with five well-defined species is recognised.

O objetivo deste trabalho foi elaborar uma bebida a partir da fermentação do extrato hidrossolúvel de soja por culturas probióticas, com adição de polpa e essência de frutas e verificar sua aceitabilidade. O número de colônias viáveis de bactérias lácticas na bebida fermentada armazenada a 5º C durante 21 dias foi superior a 107 UFC/mL, valores que estão de acordo com o exigido pela legislação vigente para produtos probiótios. As bebidas fermentadas com sabor de abacaxi e limão obtiveram aceitação significativamente maior pelos julgadores nos testes sensoriais, se comparado ao sabor de ameixa preta. Os resultados deste estudo demonstraram que o extrato hidrossolúvel de soja com 2% de sacarose possibilitou o cultivo de bactérias láticas para obtenção de uma bebida próbiótica, e adição de frutas no produto propiciou um incremento na qualidade sensorial com boa aceitação pelo consumidor.AbstractThe soy bean water soluble extract has chemical and nutritional characteristics that qualify it as a functional food; however, it has little acceptability amongst the consumers because it tastes like raw beans.

    BACKGROUND: Transfusion with red blood cells (RBC) may be needed during hip revision surgery but the appropriate haemoglobin concentration (Hb) threshold for transfusion has not been well established. We hypothesized that a higher transfusion threshold would improve ambulation after hip revision...... surgery. METHODS: The trial was registered at Clinicaltrials.gov ( NCT00906295). Sixty-six patients aged 18 years or older undergoing hip revision surgery were randomized to receive RBC at a Hb threshold of either 7.3 g/dL (restrictive group) or 8.9 g/dL (liberal group). Postoperative ambulation...... received RBC. CONCLUSIONS: A Hb transfusion threshold of 8.9 g/dL was associated with a statistically significantly faster TUG after hip revision surgery compared to a threshold of 7.3 g/dL but the clinical importance is questionable and the groups did not differ in Hb at the time of testing....

    Brysbaert and Duyck (2009) suggest that it is time to abandon the Revised Hierarchical Model (Kroll and Stewart, 1994) in favor of connectionist models such as BIA+ (Dijkstra and Van Heuven, 2002) that more accurately account for the recent evidence on nonselective access in bilingual word recognition. In this brief response, we first review the history of the Revised Hierarchical Model (RHM), consider the set of issues that it was proposed to address, and then evaluate the evidence that supp...

  7. Methods for implementing revisions to emergency operating procedures. Final report

    1984-05-01

    In response to the Three Mile Island (TMI) accident, the US Nuclear Regulatory Commission (NRC) has published the TMI Action Plan. The TMI Action Plan Item I.C.1 called for the upgrading of Emergency Operating Procedures (EOPs) at nuclear power plants. The program developed from this Action Plan item has resulted in utility efforts to: (1) revise EOPs; (2) train personnel in the use of the EOPs; and (3) implement the revised EOPs. The NRC supported the study presented in this report to identify factors which influence the effectiveness of training and implementation of revised EOPs. The NRC's major concern was the possible effects of negative transfer of training. The report includes a summary of existing methods for implementing revisions to procedures based on interviews of plant personnel, a review of the training literature applicable to the effect of previously learned procedures on the learning of and performance with revised procedures (i.e., negative transfer) and recommendations of methods and schedules for implementing revised EOPs. While the study found that the concern over negative transfer of training was not as great as anticipated, several recommendations were made. These include: (1) overtraining of operators to reduce the effect of observed negative transfer; and (2) implementation of the revised EOPs as soon as possible after training to minimize the time operators must rely upon the old EOPs after having been trained on the revised EOPs. The results of the study should be useful both to the utilities and the NRC in the development and review of EOP implementation programs

    This paper describes the legal framework in place when the revised risk estimates were announced by the International Commission for Radiological Protection (ICRP) in 1987 and how an addition to that framework enabled the revised risk estimates to be taken into account when making decisions about radiation protection practice both at plant and individual worker level. It is suggested that this a may be an early example of the use of a constraint applied generically. (author)

    2017-11-01

    The purpose of this study was to determine pain and functional outcomes following revision cubital tunnel surgery and to identify predictors of poor postoperative outcome. A retrospective cohort study was conducted of all patients undergoing revision cubital tunnel surgery over a 5-year period at a high-volume peripheral nerve center. Intraoperative findings, demographic and injury factors, and outcomes were reviewed. Average pain, worst pain, and impact of pain on self-perceived quality of life were each measured using a 10-cm visual analog scale (VAS). Function was evaluated using pinch and grip strength, as well as the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Differences in preoperative and postoperative pain, strength, and DASH were analyzed using nonparametric tests. Predictors of postoperative average pain were evaluated using odds ratios and linear regression analyses. The final cohort consisted of 50 patients (mean age: 46.3 ± 12.5 years; 29 [68%] male) undergoing 52 revision ulnar nerve transpositions (UNTs). Pain VAS scores decreased significantly following revision UNT. Strength and DASH scores demonstrated nonsignificant improvements postoperatively. Worse preoperative pain and greater than 1 prior cubital tunnel procedure were significant predictors of worse postoperative average pain VAS scores. Patients can and do improve following revision cubital tunnel surgery, particularly as it relates to pain. Intraoperative findings during the revision procedure suggest that adherence to specific principles in the primary operation is key to prevention of secondary cubital tunnel syndrome.

    To revise conversion disorder scale and to establish the psychometric properties of the revised scale. This case-control study was conducted from February to June, 2014, at the Government College University, Lahore, Pakistan, and comprised schoolchildren and children with conversion disorder. In order to generate items for revised version of conversion disorder scale, seven practising mental health professionals were consulted. A list of 42 items was finalised for expert ratings. After empirical validation, a scale of 40 items was administered on the participants and factor analysis was conducted. Of the240 participants, 120(50%) were schoolchildren (controls group) and 120(50%)were children with conversion disorder (clinical group).The results of factor analysis revealed five factors (swallowing and speech symptoms, motor symptoms, sensory symptoms, weakness and fatigue, and mixed symptoms) and retention of all 40 items of revised version of conversion disorder scale. Concurrent validity of the revised scale was found to be 0.81 which was significantly high. Similarly, discriminant validity of the scale was also high as both clinical and control groups had significant difference (pconversion disorder scale was 76% sensitive to predicting conversion disorder while specificity showed that the scale was 73% accurate in specifying participants of the control group. The revised version of conversion disorder scale was a reliable and valid tool to be used for screening of children with conversion disorder.

    The spectrum of three-times ionized bromine Br IV has been studied in the 319-2350 Å wavelength region. The spectrum was recorded on a 3-m normal incidence vacuum spectrograph at the St. Francis Xavier University, Antigonish (Canada) and 6.65-m grazing incidence spectrograph at the Zeeman laboratory (Amsterdam). The light sources used were a triggered spark and sliding spark, respectively. The ground configuration of Br IV 3d104s24p2, the excited configurations 3d104s4p3+3d104s24p (4d+5d+6d+5s+6s+7s) in the odd parity system and 3d104s24p (5p+4f+5f)+3d104s4p2 (4d+5s)+3d104p4 in the even parity system have been studied. Relativistic Hartree-Fock (HFR) and least squares fitted (LSF) parametric calculations were used to interpret the observed spectrum. 120 Levels of Br IV have now been established, 58 being new. Among 424 spectral lines, 277 are newly classified. The levels 4s4p35S2, 4s24p4d 3F4 and 4p5p (3P0, 1, 3D1, 2, 3S1) are revised. We estimate the accuracy of our measured wavelength for sharp and unblended lines to be ±0.005 Å. The ionization limit is determined as 385,390±100 cm-1 (47.782±0.012 eV).

  16. Revised DTI Guidelines for Petroleum Measurement

    Energy Technology Data Exchange (ETDEWEB)

    Griffin, D.; Philip, L.N.

    1997-07-01

    The DTI's guidelines on petroleum measurement have been extensively revised and enlarged. The new guidelines cover a much wider scope of measurement situations than before. Included in the new issue is guidance on allocation measurement, well testing, multiphase flow measurement, new technology acceptance procedures and operating procedures for different types of measurement systems. Significant changes have taken place in recent years both in the way the oil and gas industry conducts its business and in the fiscal regime operated by the UK government. New developments in flow measurement have progressed to such an extent that they have now been adopted by the industry or are close to being adopted as beneficial methods of the measurement of hydrocarbons in whatever form they present themselves for measurement. The rapid pace of development has left the standards-making bodies behind and in some cases there is insufficient quality data to enable the standards makers to produce guidance of the generic type appropriate for national or international standards. The case-by-case approach of the DTI in approving methods of measurement lends itself better to consideration of new technology where there may be no existing standards. These, amongst other considerations, make it appropriate for the DTI to extend the scope of its guidance into these new areas. The policy developments behind the changes in the new guidelines are not static and this new document has been produced in response to an evolutionary process which is still continuing but it is right to collate and make defining statements from time to time to put on record the current status of measurement requirements for the purpose of attaining DTI approval.

  17. Formative research: pretesting, revising, and more pretesting.

    Zimmerman, M; Steckel, L

    1985-01-01

    Thorough and extensive pretesting is the formative research technique that the Program for the Introduction and Adaptation of Contraceptive Technology (PIACT) and its sister organization, the Program for Appropriate Technology in Health (PATH), rely on to develop well-understood and culturally appropriate print materials. Formative research is defined as evaluation activities that occur during a project to determine if the objectives are being met and, if not, to modify the project's direction to ensure that they are. Before materials are finalized or printed, an interviewer should pretest them with representatives of the target population to determine if the intended message is being conveyed and if it is clear and acceptable to them. Pretesting should be done while the materials are still in an unfinished state so audience-generated alterations can be made easily. Revised materials also should be tested until they communicate the inforamtion as intended. Due to the fact that PIACT/PATH work with countries where large percentages of the population are illiterate, its motivational and instructional materials rely on pictures to convey the message. Often, pictures are augmented by a line or 2 of simple text in the local language. This text also requires careful pretesting. Examples from the field demonstrate the importance of pretesting to assure that print materials are appropriate to the group for whom they are being developed. The examples deal with sympbols, positive messages, the use of common objects, extraneous detail, messages about time, and text. Through pretesting, PIACT/PATH has learned that there can be a large discrepancy between what materials developers intend to convey and what the audience understands. Pretesting is an essential formative technique that builds upon information gathered during the materials development process, ensuring the message designer that the materials will effectively address the needs of the target audience.

  18. Systematic revision of the Phorusrhacidae (Aves: Ralliformes

    Directory of Open Access Journals (Sweden)

    Alvarenga Herculano M.F.

    2003-01-01

    Full Text Available Fossil remains of birds belonging to the family Phorusrhacidae were studied in several museums of South America, North America and Europe, the main objective being to characterize this family and solve the chaotic state of the nomenclature and classification of these birds. Reconstruction of some species has been done, with the purpose of having an idea about the size, body weight, posture and habit based in their skeletons. The European species, Ameghinornis minor and Aenigmavis sapea are refuted as belonging to this family. Also several forms described from the Tertiary of Argentina are refuted, because they are based on inadequate segments of the skeleton for a good identification, as is the case of the genera Cunampaia, Smiliornis, Pseudolarus, Lophiornis and Riacama, frequently refered to as belonging to the Phorusrhacidae. The Phorusrhacidae family probably originated in South America, since the end of the Cretaceous, as a result of an endemism formed by the isolation of this landmass. During the end of the Pliocene, with the emersion of the Panama isthmus, the family spread to the North America where at least one species is known Titanis walleri, which perhaps represents the last known species of this family, probably becoming extinct in the beginning of the Pleistocene. A systematic revision has been conducted, dealing with the countless problems of nomenclature, and the Phorusrhacidae is now composed of five subfamilies, which are: Brontornithinae, Phorusrhacinae, Patagornithinae, Psilopterinae and Mesembriornithinae in which 13 genera and 17 species are considered. Characters of all taxa are described and a geochronological distribution of all species is presented.

    In order to fulfill the requirement to prove HANARO fuel integrity when irradiated at a power greater than 112.8 kW/m, which was imposed during HANARO licensing, and to verify the irradiation performance of HANARO fuel, the in-pile irradiation test of HANARO fuel has been performed. Two types of test fuel, the un-instrumented Type A fuel for higher burnup irradiation in shorter period than the driver fuel and the instrumented Type B fuel for higher linear heat rate and precise measurement of irradiation conditions, have been designed and fabricated. The test fuel assemblies were irradiated in HANARO. The two Type A fuel assemblies were intended to be irradiated to medium and high burnup and have been discharged after 69.9 at% and 85.5 at% peak burnup, respectively. Type B fuel assembly was intended to be irradiated at high power with different instrumentations and achieved a maximum power higher than 120 kW/m without losing its integrity and without showing any irregular behavior. The Type A fuel assemblies were cooled for about 6 months and transported to the IMEF(Irradiated Material Examination Facility) for consequent evaluation. Detailed non-destructive and destructive PIE (Post-Irradiation Examination), such as the measurement of burnup distribution, fuel swelling, clad corrosion, dimensional changes, fuel rod bending strength, micro-structure, etc., has been performed. The measured results have been analysed/compared with the predicted performance values and the design criteria. It has been verified that HANARO fuel maintains proper in-pile performance and integrity even at the high power of 120 kw/m up to the high burnup of 85 at%. This report is the revision of KAERI/TR-1816/2001 on the irradiation test for HANARO fuel.

    Little published information is available about access failure in children undergoing chronic peritoneal dialysis. Our objectives were to evaluate frequency, risk factors, interventions, and outcome of peritoneal dialysis access revision. Data were derived from 824 incident and 1629 prevalent patients from 105 pediatric nephrology centers enrolled in the International Pediatric Peritoneal Dialysis Network Registry between 2007 and 2015. In total, 452 access revisions were recorded in 321 (13%) of 2453 patients over 3134 patient-years of follow-up, resulting in an overall access revision rate of 0.14 per treatment year. Among 824 incident patients, 186 (22.6%) underwent 188 access revisions over 1066 patient-years, yielding an access revision rate of 0.17 per treatment year; 83% of access revisions in incident patients were reported within the first year of peritoneal dialysis treatment. Catheter survival rates in incident patients were 84%, 80%, 77%, and 73% at 12, 24, 36, and 48 months, respectively. By multivariate logistic regression analysis, risk of access revision was associated with younger age (odds ratio, 0.93; 95% confidence interval, 0.92 to 0.95; P<0.001), diagnosis of congenital anomalies of the kidney and urinary tract (odds ratio, 1.28; 95% confidence interval, 1.03 to 1.59; P=0.02), coexisting ostomies (odds ratio, 1.42; 95% confidence interval, 1.07 to 1.87; P=0.01), presence of swan neck tunnel with curled intraperitoneal portion (odds ratio, 1.30; 95% confidence interval, 1.04 to 1.63; P=0.02), and high gross national income (odds ratio, 1.10; 95% confidence interval, 1.02 to 1.19; P=0.01). Main reasons for access revisions included mechanical malfunction (60%), peritonitis (16%), exit site infection (12%), and leakage (6%). Need for access revision increased the risk of peritoneal dialysis technique failure or death (hazard ratio, 1.35; 95% confidence interval, 1.10 to 1.65; P=0.003). Access dysfunction due to mechanical causes doubled the risk

    The spectrum of three-times ionized bromine Br IV has been studied in the 319–2350 Å wavelength region. The spectrum was recorded on a 3-m normal incidence vacuum spectrograph at the St. Francis Xavier University, Antigonish (Canada) and 6.65-m grazing incidence spectrograph at the Zeeman laboratory (Amsterdam). The light sources used were a triggered spark and sliding spark, respectively. The ground configuration of Br IV 3d 10 4s 2 4p 2 , the excited configurations 3d 10 4s4p 3 +3d 10 4s 2 4p (4d+5d+6d+5s+6s+7s) in the odd parity system and 3d 10 4s 2 4p (5p+4f+5f)+3d 10 4s4p 2 (4d+5s)+3d 10 4p 4 in the even parity system have been studied. Relativistic Hartree–Fock (HFR) and least squares fitted (LSF) parametric calculations were used to interpret the observed spectrum. 120 Levels of Br IV have now been established, 58 being new. Among 424 spectral lines, 277 are newly classified. The levels 4s4p 35 S 2 , 4s 2 4p4d 3 F 4 and 4p5p ( 3 P 0,1 , 3 D 1,2 , 3 S 1 ) are revised. We estimate the accuracy of our measured wavelength for sharp and unblended lines to be ±0.005 Å. The ionization limit is determined as 385,390±100 cm −1 (47.782±0.012 eV). -- Highlights: • The spectrum of Br was recorded on a 3-m spectrograph with triggered spark source. • Atomic transitions for Br IV were identified to established new energy levels. • CI calculations with relativistic corrections were made for theoretical predictions. • Weighted oscillator strength (gf) and transition probabilities (gA) were calculated. • Ionization potential of Br IV was determined experimentally

    Nuclear safety policy in Korea is currently declared in the Nuclear Safety Charter as the highest tier document and safety principles and directions are announced in the Nuclear Safety Policy Statement. As the circumstances affecting on the nuclear safety policy change, it needs to revise the Statement. This study aims to develop the revised Nuclear Safety Policy Statement to declare that securing safety is a prerequisite to the utilization of nuclear energy, and that all workers in nuclear industry and regulatory body must adhere to the principle of priority to safety. As a result, two different types of revision are being prepared as of August. One is based on the spirit of Nuclear Safety Charter as well as the direction of future-oriented safety policies including the changes in the environment after declaration of the Statement. The other is to declare the fundamental safety objective and safety principles as the top philosophy of national nuclear safety policy by adopting the '10 Safety Principles in IAEA Safety Fundamental' instead of the current Charter. Both versions of revision are subject to further in-depth discussion. However once the revision is finalized and declared, it would be useful to accomplish effectively the organizational responsibilities and to enhance the public confidence in nuclear safety by performing the regulatory activities in a planned and systematic manner and promulgating the government's dedication to priority to safety

  6. Regional sensitivity analysis using revised mean and variance ratio functions

    International Nuclear Information System (INIS)

    Wei, Pengfei; Lu, Zhenzhou; Ruan, Wenbin; Song, Jingwen

    2014-01-01

    The variance ratio function, derived from the contribution to sample variance (CSV) plot, is a regional sensitivity index for studying how much the output deviates from the original mean of model output when the distribution range of one input is reduced and to measure the contribution of different distribution ranges of each input to the variance of model output. In this paper, the revised mean and variance ratio functions are developed for quantifying the actual change of the model output mean and variance, respectively, when one reduces the range of one input. The connection between the revised variance ratio function and the original one is derived and discussed. It is shown that compared with the classical variance ratio function, the revised one is more suitable to the evaluation of model output variance due to reduced ranges of model inputs. A Monte Carlo procedure, which needs only a set of samples for implementing it, is developed for efficiently computing the revised mean and variance ratio functions. The revised mean and variance ratio functions are compared with the classical ones by using the Ishigami function. At last, they are applied to a planar 10-bar structure

    Full Text Available BACKGROUND Syndesmotic disruptions are often seen in ankle fractures. Malreduction of these fractures can result in arthritis and instability. A proportion of these patients with malreduction require revision fixation. This study presents the results of revision fixation in such patients, using the Ankle TightRope ® (Arthrex system. METHODS Between January 2000 to December 2009, 124 patients who underwent ankle fracture fixations with syndesmotic stabilisation were analysed. Out of 124 patients, 8 patients were diagnosed with failure of primary stabilisation (based on radiological and clinical criteria and subjected to revision fixation using the Ankle TightRope ® (Arthrex system. Followup was done at periodic time intervals of 3, 6 and 12 months. Both clinical and radiological assessment was performed. Complications and duration of hospital stay was recorded. Functional evaluation was performed using the American Orthopaedic Foot and Ankle Society (AOFAS scoring system. RESULTS Five patients had good results, one satisfactory and two had poor outcomes. CONCLUSIONS Ankle TightRope ® fixation is an alternative method of stabilisation in patients who require revision syndesmosis fixation. Further studies are required to evaluate this method of revision stabilisation as compared to screws.

    The Application of Human Factors to the design of Man-Machine Interfaces System(MMIS) in the nuclear power plant is essential to the safety and productivity of the nuclear power plants, human factors standards and guidelines as well as human factors analysis methods and experiments are weightily used to the design application. A Korean engineering company has developed a human factors engineering guideline, so-call HF-010, and has used it for human factors design, however the revision of HF-010 is necessary owing to lack of the contents related to the advanced MMI(Man-Machine Interfaces). As the results of the reviews of HF-010, it is found out that the revision of Section 9. Computer Displays of HF-010 is urgent, thus the revision was drafted on the basis of integrated human factors design guidelines for VDT, human factors design guidelines for PMAS SPADES display, human factors design guidelines for PMAS alarm display, and human factors design guidelines for electronic displays developed by the surveillance and operation support project of KOICS. The draft revision of HF-010 Section 9 proposed in this report can be utilized for the human factors design of the advanced MMI, and the high practical usability of the draft can be kept up through the continuous revision according to the advancement of digital technology

  9. Anomalies of Nuclear Criticality, Revision 6

    This report is revision 6 of the Anomalies of Nuclear Criticality. This report is required reading for the training of criticality professionals in many organizations both nationally and internationally. This report describes many different classes of nuclear criticality anomalies that are different than expected. An anomaly is defined as something not in keeping with expected notions of fitness and order, a departure from the regular arrangement or general rule. In reviewing the literature and experimental data on nuclear criticality and the conditions under which a fission chain reaction can be achieved, a number of anomalies have come to light. The actinide group is composed of the fourteen elements beginning with thorium, Atomic No. 90, and ending with lawrencium, Atomic No. 103. There are about 220 known actinide isotopes, most of which are believed capable of supporting neutron chain reactions. Although every element in the actinide group has at least one isotope believed capable of supporting a chain reaction, from a practical point of view regarding the time for chemical processing, only those nuclides with half-lives more than several weeks are of obvious concern in criticality safety. Forty-six of the nuclides are known to have half-lives greater than six weeks. The selection of six weeks is somewhat arbitrary. There may well be shorter-lived nuclides of concern in criticality safety. These 46 nuclides are identified in Figure 44. Of the 46 nuclides, 4 are known and 37 are believed to be capable of supporting chain reactions, and 5 are known or believed to not support a chain reaction. Figure 44 was constructed in the format used for the Chart of the Nuclides.(1) Figure 44 also shows the distinction between fissile and fissible nuclides. The actinides derive their name from actinium (Atomic No. 89) because they tend to maintain an actinium-like electron structure as the fourteen inner electrons are added to the 5f electron shell. Actually, electrons do

    In April 1992, the NRC staff presented to the Commissioners the draft NUREG open-quotes Revised Accident Source Terms for Light-Water Nuclear Power Plants.close quotes This document is the culmination of more than ten years of NRC-sponsored research and represents the first change in the NRC's position on source terms since TID-14844 was issued in 1962. The purpose of this paper is to investigate the impact of the revised source terms on the current approach to analyzing control room habitability as required by 10 CFR 50. Sample calculations are presented that identify aspects of the model requiring clarification before the implementation of the revised source terms. 6 refs., 4 tabs

  11. The association between metal allergy, total knee arthroplasty, and revision

    BACKGROUND AND PURPOSE: It is unclear whether delayed-type hypersensitivity reactions against implanted metals play a role in the etiopathogenesis of malfunctioning total knee arthroplasties. We therefore evaluated the association between metal allergy, defined as a positive patch test reaction...... to common metal allergens, and revision surgery in patients who underwent knee arthroplasty. PATIENTS AND METHODS: The nationwide Danish Knee Arthroplasty Register, including all knee-implanted patients and revisions in Denmark after 1997 (n = 46,407), was crosslinked with a contact allergy patch test......, the prevalence of cobalt and chromium allergy was markedly higher. Metal allergy that was diagnosed before implant surgery appeared not to increase the risk of implant failure and revision surgery. INTERPRETATION: While we could not confirm that a positive patch test reaction to common metals is associated...

    Two hundred participants, 50 in each of four age ranges (19 – 29; 30 – 49, 50 – 69, 70 – 90) were tested for short term working memory, speed of processing and on-line processing of three types of sentences in which an initially assigned syntactic structure and/or semantic interpretation had to be revised. Self-paced reading times were longer for the segments which signaled the need for revision, and there were interactions of age and sentence type and of speed of processing and sentence type, but not of working memory and sentence type, on reading times for these segments. The results provide evidence that working memory does not support the processes that revise the structure and interpretation of sentences and discourse. PMID:25485458

    The Ministry of International Trade and Industry has revised downward its long-term outlook on energy supply and demand, lowering the estimated primary energy demand for fiscal 2000 from 600 million tons in oil equivalent to 540 MTOE, and reducing total power demand for fiscal 2000 from 899.1 billion kWh to 838 billion. In this content, the outlook for installed nuclear capacity has been revised downward from 62,000 MW to 53,500 MW. This revision of the power supply-demand outlook was reported on Oct. 1 to the supply and demand committee (Chairman - Yoshihiko Morozumi, Adviser to Nippon Schlum-berger) of the Electric Utility Industry Council; the energy supply-demand outlook was decided on Oct. 14 by the MITI Supply and Demand Subcommittee of the Advisory Committee for Energy and reported on Oct. 16 to the conference of ministers concerned with energy.

  14. Revised accident source terms for light-water reactors

    Energy Technology Data Exchange (ETDEWEB)

    Soffer, L. [Nuclear Regulatory Commission, Washington, DC (United States)

    1995-02-01

    This paper presents revised accident source terms for light-water reactors incorporating the severe accident research insights gained in this area over the last 15 years. Current LWR reactor accident source terms used for licensing date from 1962 and are contained in Regulatory Guides 1.3 and 1.4. These specify that 100% of the core inventory of noble gases and 25% of the iodine fission products are assumed to be instantaneously available for release from the containment. The chemical form of the iodine fission products is also assumed to be predominantly elemental iodine. These assumptions have strongly affected present nuclear air cleaning requirements by emphasizing rapid actuation of spray systems and filtration systems optimized to retain elemental iodine. A proposed revision of reactor accident source terms and some im implications for nuclear air cleaning requirements was presented at the 22nd DOE/NRC Nuclear Air Cleaning Conference. A draft report was issued by the NRC for comment in July 1992. Extensive comments were received, with the most significant comments involving (a) release fractions for both volatile and non-volatile species in the early in-vessel release phase, (b) gap release fractions of the noble gases, iodine and cesium, and (c) the timing and duration for the release phases. The final source term report is expected to be issued in late 1994. Although the revised source terms are intended primarily for future plants, current nuclear power plants may request use of revised accident source term insights as well in licensing. This paper emphasizes additional information obtained since the 22nd Conference, including studies on fission product removal mechanisms, results obtained from improved severe accident code calculations and resolution of major comments, and their impact upon the revised accident source terms. Revised accident source terms for both BWRS and PWRS are presented.

    US Department of Energy Headquarters initiated efforts to revise DOE Order 5820.2A, ``Radioactive Waste Management``. The purpose of the revision is to enhance DOE waste management requirements, reflect new DOE organizational responsibilities, and consolidate requirements for management of all waste, under the responsibility of Environmental Restoration and Waste Management, into a single order. This paper discusses the revision philosophy, objectives of the revision, and strategy for the revision. Issues being considered for inclusion in the revision and recommended methods of resolving each issue are also discussed.

  16. Milgrom's revision of Newton's laws: Dynamical and cosmological consequences

    1984-01-01

    Milgrom's recent revision of Newtonian dynamics was introduced to eliminate the inference that large quantities of invisible mass exist in galaxies. I show by simple examples that a Milgrom acceleration, in the form presented so far, implies other far-reaching changes in dynamics. The momentum of an isolated system is not conserved, and the usual theorem for center-of-mass motion of any system does not hold. Naive applications require extreme caution. The model fails to provide a complete description of particle dynamics and should be thought of as a revision of Kepler's laws rather than Newton's

  17. Respiratory protection standard: comments on OSHA's proposed revision.

    On November 15, 1994, the Occupational Safety and Health Administration (OSHA) published in the Federal Register (59:58884-58956) the draft of a proposed revision of the Respiratory Protection Standard. One of OSHA's oldest standards, the Respiratory Protection Standard defines the conduct of the employer (eg, hospital) with respect to respirator training, fit testing, medical examinations, use, storage, and so on. The proposed revision appears to have been drafted with no consideration for its effect on healthcare workers or the healthcare industry. SHEA has prepared the following comments to OSHA, which have been submitted to the docket and will be presented at public hearings later this month.

  18. Signs of revision in Don Quixote, Part II

    Directory of Open Access Journals (Sweden)

    Gonzalo Pontón

    2016-11-01

    Full Text Available This article provides new evidences in favour of the hypothesis that Cervantes, after finishing Don Quixote, Part II, partially revised the original, introducing some significant changes and additions, mainly in the last chapters. The analysis of some narrative inconsistencies, that cannot be interpreted as mere mistakes but as significant textual traces, reveals a process of re-elaboration –a process that affects at least four sections of the novel. Most of the evidence gathered here suggests that this revision is closely linked to Avellaneda’s continuation, in the sense that Cervantes tried to challenge the apocriphal Quixote making last-time interventions in his own text.

    Probability and Statistics, Revised Edition deals with the history of probability, describing the modern concept of randomness and examining "pre-probabilistic" ideas of what most people today would characterize as randomness. This revised book documents some historically important early uses of probability to illustrate some very important probabilistic questions. It goes on to explore statistics and the generations of mathematicians and non-mathematicians who began to address problems in statistical analysis, including the statistical structure of data sets as well as the theory of

    The Active Sites Environmental Monitoring Program (ASEMP), initiated in 1989, provides early detection and performance monitoring of active low-level-waste (LLW) and transuranic (TRU) waste facilities at Oak Ridge National Laboratory (ORNL). Several changes have recently occurred in regard to the sites that are currently used for waste storage and disposal. These changes require a second set of revisions to the ASEMP program plan. This document incorporates those revisions. This program plan presents the organization and procedures for monitoring the active sites. The program plan also provides internal reporting levels to guide the evaluation of monitoring results
