    Full Text Available La popularización de la combinación de ácidos poliláctico y poliglicólico ha hecho que estos nuevos materiales se utilicen cada vez más en la osteosíntesis maxilofacial, no solo en su aplicación pediátrica, sino también en adultos. Aunque todavía presentan algunas desventajas en relación con el titanio, como la mayor incomodidad de uso y el coste económico, la experiencia acumulada demuestra que es una alternativa válida a la osteosíntesis con titanio en la mayoría de las situaciones clínicas. En este artículo se analizan las características y cualidades de los materiales reabsorbibles empleados en osteosíntesis maxilofacial. Así mismo, se discuten las ventajas y desventajas de ambos tipos de osteosíntesis y se documentan las indicaciones actuales de la osteosíntesis reabsorbible basándonos en nuestra experiencia y en la revisión de la literatura.Resorbable plates and screws composed of polylactic and polyglycolic acid, as internal fixation devices have gained widespread use during recent years in pediatric and also adult patients. Although these materials show some disadvantages when compared with titanium plates, such as discomfort and economical cost, accumulated experience shows that resorbable ostheosynthesis is a reliable alternative to the titanium osteosynthesis used in most clinical cases. In this paper we analyze the main characteristics of resorbable materials used in maxillofacial osteosynthesis. We discuss the advantages and disadvantages of both types of osteosynthesis and the indications for resorbable ostheosynthesis at the present time, based on our experience and on a revision of the literature.

    2000-01-01

    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.

    Full Text Available La translocación del tercio medio facial, técnica consistente en la movilización del esqueleto centrofacial pediculado a los tejidos blandos, ha demostrado permitir un amplio acceso para el abordaje de lesiones situadas en las regiones faciales profundas y la región central de la base del cráneo. Uno de los principales inconvenientes que presentaba este abordaje en niños era la fijación del esqueleto con placas y tornillos de titanio, ya que podía interferir en el crecimiento del hueso en desarrollo. Todo ello planteaba el problema de una segunda intervención para la retirada del material, aumentando, de forma significativa, la morbilidad del procedimiento. Como solución al problema se comercializa, a partir de la década de 1980, el material de osteosíntesis reabsorbible. Presentamos a una paciente de 13 años de edad diagnosticada de un cordoma localizado en el clivus. Como abordaje, se realiza una translocación bilateral del tercio medio facial y se utiliza, para la fijación del esqueleto facial, un nuevo sistema de placas y tornillos reabsorbibles basado en ultrasonidos (Sonic Weld®. KLS Martin, LP, Jacksonville, Florida, USA. Se describen los principales abordajes a las regiones faciales profundas y centromediales de la base del cráneo, las principales variantes de la translocación del tercio medio facial, la técnica de aplicación del nuevo sistema Sonic Weld® y sus diferencias principales respecto a los sistemas reabsorbibles tradicionales.Mid-facial translocation, which involves mobilization of the central facial skeletal structures together with soft tissue pedicles, provides generous access to the anterior and central regions of the skull base. One of the drawbacks of this approach in children is skeletal fixation with titanium osteosynthesis plates and screws, which may affect the growth of developing bone. Consequently, a second intervention is required to remove titanium osteosynthesis material, which increases the

    Rivera Pacheco, Andres

    El proposito de esta investigacion, un estudio cualitativo de caso, fue comparar y contrastar el curriculo vigente de la Escuela de Optometria de la UIAPR con las competencias y estandares requeridos por las agencias de acreditacion y de revalida. Con este proposito, decidimos realizar una revision y un analisis de documentos: el prontuario de cada uno de los cursos de los curriculos implantados en el 1993 y en el 2001; las competencias y estandares establecidos por las agencias de revalida y de acreditacion; y las estadisticas en las que se analiza el porcentaje de estudiantes que aprueban cada una de las partes de los examenes de revalida entre el 1998 al 2003. Se realizaron entrevistas dirigidas para dar apoyo y complementar la revision y el analisis de estos documentos. Los participantes de las entrevistas fueron tres estudiantes de la clase de optometria del 2004 (ultima clase del curriculo del 1993); tres estudiantes de la clase de optometria del 2005 (primera clase graduanda del curriculo vigente) y tres profesores y/o directores de los Departamentos de Ciencias Basicas, Ciencias Clinicas y Cuidado al Paciente. Esta investigacion se enmarco en el modelo de evaluacion curricular de discrepancia de Malcolm Provus y en el modelo de desarrollo basado en competencias. Uno de los hallazgos mas importantes del estudio es que los cambios que se implantaron al curriculo del 2001 no han logrado que los estudiantes mejoren su ejecucion en los examenes de revalida. Por otro lado, se encontro que el curriculo vigente atiende completamente los estandares de la practica de Optometria, pero no las competencias. Esta informacion fue validada mediante el uso de una tabla de cotejo para el analisis de los cursos y de la informacion obtenida de las entrevistas. El estudio determina y concluye que existen discrepancias entre los prontuarios de los cursos del curriculo y las competencias requeridas por la agencia de revalida. Segundo, que el Departamento de Ciencias Basicas es el

    Full Text Available Esta investigación busca comprobar empíricamente el paradigma entre estrategiaestructura y equifinalidad en empresas del noreste de México. Se llevó al cabo un estudio a través de la aplicación de cuestionarios a negocios de esa parte del país. Se consideró como variable independiente la existencia del modelo de Chandler acerca de que la “estructura organizacional sigue a la estrategia”. La variable dependiente, se establece como la obtención de resultados equifinales (igualmente finales, con o sin la existencia del paradigma de estrategia-estructura. Dos contribuciones emergen de este estudio. La primera consiste en haber encontrado que efectivamente existe una relación entre estrategia y estructura en las empresas investigadas. La segunda, y más importante, es que se evidenció, con prueba empírica, el paradigma de equifinalidad. Se necesita mayor investigación para poder determinar las razones para el funcionamiento de este paradigma. La naturaleza holística de la Administración Estratégica puede ser la que explique el éxito final, “sin importar los inicios”.

    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.

Foram pesquisadas as bibliotecas virtuais MedLine, Lilacs e Scielo. A amostra foi constituída por 16 publicações que foram analisadas quanto aos fatores de erro e propostas ou não de barreiras para erro. Destaca-se que estudos em relação a erros em medicação são relativamente recentes e poucos se referem à realidade brasileira. Entre os motivos apontados para a ocorrência de erros tem-se a ilegibilidade da letra do médico na prescrição, a carga de trabalho excessiva da enfermagem, interrupções freqüentes durante as etapas da prescrição e administração de medicamentos, número reduzido de funcionários e inexperiência do profissional de enfermagem que prepara a medicação. Três estudos apresentaram propostas de barreiras relacionadas à informatização do processo.Se trata de una revisión bibliográfica con el objetivo de analizar las publicaciones de enfermeros acerca de errores con la terapia medicamentosa indexados en bancos de datos entre 2000 a 2006.

    Full Text Available Spinal cord injuries remain an important factor of morbimortality in current society, involving mainly males from adolescence to adulthood. Among the sequelae caused by spinal cord injuries, the impairment of the sexual system is highly relevant since it affects the quality of sexual life and paternity. Infertility is secondary to multiple events such as erectile dysfunction, anejaculation, seminal biochemical modification and morphology of spermatozoa. Current therapies for the infertile spinal cord injured patient focus on the ejaculation stimulus followed by intrauterine insemination, leaving seminal low quality as the major factor of infertility in these patients. In this scenario, therapy with hyperbaric oxygenation, which is still being studied, represents an alternative treatment since it focuses on the central nervous system injured by the trauma and the testicular tissue in order to decrease spinal damage and to preserve the physiological regulation of the urogenital system as a form of avoiding infertility.La lesión de la médula espinal sigue siendo una causa importante de morbilidad y mortalidad en la sociedad actual, que afecta principalmente a hombres en la adolescencia a la edad adulta. Entre las varias secuelas resultantes de lesiones de la médula espinal, el deterioro del sistema sexual es de gran relevancia una vez que afectan la calidad de la vida sexual y la paternidad. La infertilidad es secundaria a varios eventos, tales como la disfunción eréctil, aneyaculación, modificación bioquímica seminal y la morfología de los espermatozoides. Los tratamientos para la infertilidad post-TRM, en general, tienen por objeto estimular la eyaculación seguida de inseminación in vitro, siendo la baja calidad seminal el factor determinante de la infertilidad de estos pacientes. En este escenario, la terapia con oxigenación hiperbárica, aún en estudio, representa un tratamiento alternativo ya que actúa sobre el sistema nervioso

    Full Text Available El melodrama clásico, mal entendido como Woman´s Film, construye en la mayoría de sus relatos clásicos a la mujer como significante de pasividad y renuncia. Desde los estudios de género, y más concretamente desde la teoría fílmica feminista, se ha analizado exhaustivamente un subgénero cinematográfico que se entiende como fundamental, ya que saca a la luz las restricciones que les son impuestas a las mujeres en la sociedad patriarcal en general y más concretamente en la institución familiar. Mi vida sin mí (Isabel Coixet, 2003 se enmarca, en apariencia, dentro del corte clásico del subgénero melodramático familiar para subvertir, después, sus propias convenciones. Isabel Coixet se desmarca conscientemente de la identificación masoquista que proporciona el melodrama a la espectadora, critica la representación clásica de la mujer y se aleja de la oposición predominante en el cine entre maternidad-sexualidad. La directora española construye una mujer como sujeto múltiple, contradictorio y en progreso que no se conforma con proponer vías de resistencia a las imposiciones patriarcales, y que no reduce su identidad a la faceta maternal. La mujer del melodrama de Coixet es útil en tanto modelo de identificación diegético y extradiegético para la organización de un nuevo sistema –social, cinemático, etc.– que no ponga sus bases en el binomio dominación-sumisión. Haciendo esto, Isabel Coixet expande los límites del melodrama hasta el terreno del feminismo.Palabras clave: melodrama familiar, Woman´s Film, Women´s Cinema, género, maternidad, patriarcado, espectatoriedad, sexualidad, feminismo.AbstractClassic melodrama, misunderstood as `Woman´s Film´, has usually intented to build women as a signifier of passivity and resignation.

    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.

Ésta se levantó sobre las herencias del pasado y se caracterizó, de manera fundamental, por el tránsito desde un modelo estatal-desarrollista hacia uno de tipo empresarial, por el aparecimiento de nuevos agentes sociales, el multipartidismo político, la regionalización nacional, la presencia multicultural y la inserción del país en nuevas relaciones internacionales. Pero esos procesos trajeron como consecuencias centrales: la edificación de una economía inequitativa, una sociedad tensionada, la desestructuración institucional, la precarización del trabajo y la debilidad con la que la nación ha enfrentado el nuevo mundo unipolar. Todo ello ha configurado un cuadro de riesgos para la incipiente democracia. El Ecuador contemporáneo tiene, por tanto, una serie de desafíos económicos, sociales y políticos para escapar a la inestabilidad que ha acompañado a la construcción de su modernización democrática.___________________ABSTRACT:In 1979, after one decade of military dictatorships, the longest constitutional phase in the history of Ecuador was initiated.

  20. Philippines revises power plans

    Energy Technology Data Exchange (ETDEWEB)

    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.

    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

  9. 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.

    Full Text Available This article focuses on the women’s magazine Ellas, published in the mid-nineteenth century in Madrid, and discusses its relationship with other approximately contemporary magazines and newspapers in order to contribute to a reconstruction of the history of women’s publications in the Spanish press. The approach is based on an analysis of the text of each issue of the magazine and comparison with other publications, where applicable. Key features of the article include a reflection on the social rights of women, an attempt to analyse the main differences between women and men and defining features of sexual gender, the need for women’s education, etc. Studying the magazine’s content clearly reveals a continual tension between progressive and conservative ideas typical of the historical context in which gender studies emerged in Spain.Este artículo centra su atención en la revista para mujeres Ellas, publicada a mediados del siglo XIX en Madrid. Analiza, asimismo, la relación de esta publicación con algunas otras revistas y periódicos de su contexto histórico próximo, con el fin de contribuir a la reconstrucción de una Historia de las publicaciones para mujeres en la prensa española. Para ello se utiliza el análisis de textos que forman parte de los números que componen la revista, así como el análisis comparativo entre publicaciones, cuando es pertinente. Entre los aspectos de mayor interés que el artículo pone de relieve se encuentra la reflexión sobre los derechos sociales de las mujeres, el intento de análisis de las principales diferencias entre mujeres y hombres y de los rasgos definitorios de los géneros sexuales, la necesidad de educación de las mujeres, entre otros. El estudio del contenido de la publicación revela claramente una tensión contradictoria continua entre las ideas progresistas y las ideas conservadoras propias del momento histórico que dieron origen en España al nacimiento de los estudios de género.

    Lo "gnomone" di cui si parla in questo libro non è quello stilo, più o meno monumentale, la cui ombra indica l'ora solare, ma un semplice strumento matematico: una figura geometrica, piana o solida, che aggiunta a un'altra ne genera una simile. Si tratta quindi di una tecnica, ampiamente diffusa nell'antichità, atta a ingrandire o rimpicciolire una forma conservandone l'aspetto. Lo gnomone non aveva solo importanza geometrica. Dalla semplice operazione di correzione "gnomonica" di una figura sono dipesi infatti la stessa nozione di numero, la definizione di vari concetti dell'Analisi e alcuni tra i principali algoritmi numerici e algebrici della matematica.

    Full Text Available O nascimento do segundo filho é uma fase específica do ciclo vital familiar, que acarreta mudanças, especialmente para o primogênito. O presente artigo examina questões teóricas e estudos empíricos acerca das implicações emocionais da chegada de um irmão para o primogênito. Os estudos sugerem que este momento é especial tanto para a mãe, que precisa cuidar de dois filhos, quanto para o primogênito, que deixa de ser filho único e precisa compartilhar os cuidados maternos. A literatura que tem se dedicado ao impacto do nascimento de um segundo filho no primogênito apresenta resultados contraditórios: se, por um lado, aponta mais comportamentos regressivos, de dependência, do primogênito, por outro, indica maior independência. A literatura ainda considera os comportamentos regressivos como "negativos", enquanto os de independência como "positivos" e de crescimento. Torna-se fundamental identificar momentos de transição na família, passíveis de mudanças, a fim de ajudar os pais a compreenderem que a criança tem seu próprio ritmo de desenvolvimento rumo à independência e pode apresentar comportamentos mais regressivos nos momentos de transição.El nacimiento del segundo hijo se caracteriza por ser una etapa específica del ciclo vital familiar, generando cambios, en especial al primogénito.

  4. Failure of aseptic revision total knee arthroplasties.

    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.

  5. 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 Dado que en la actualidad hay mayores posibilidades para practicar una lengua extranjera en su contexto natural con nativohablantes, es imprescindible poseer una cierta competencia intercultural a fin de que este diálogo pueda llevarse a cabo exitosamente. Sin embargo, los libros de texto convencionales editados en el país de origen de la lengua estudiada difícilmente pueden cubrir este requisito, puesto que las particularidades culturales de una sociedad sólo se vuelven interculturales al compararlas con la cultura de los alumnos. En el artículo presente se proponen varios ejercicios enfocados al aprendizaje intercultural en donde no sólo se aprenden las normas, reglas y actitudes de la cultura meta, en este caso de Alemania, Austria y Suiza, sino que también se estimula la reflexión sobre las de la cultura propia. Esta sensibilización cultural es indispensable para lograr una comunicación equitativa entre personas de diferentes culturas.

    1991-12-01

    The present publication is an updated version of the IAEA Assessment of Safety Significant Events Team (ASSET) Guidelines, IAEA-TECDOC-573, published in 1990. Sections 5 and 6 include revised definitions and investigation guidelines for identification of both direct and root causes. These revisions were recommended by a Consultants Meeting held in Vienna on 3-7 December 1990. This guidance is not intended to infringe an expert's prerogative to investigate additional items. Its main purpose is to provide a basic structure and ensure consistency in the assessments. Use of the ASSET guidelines should also facilitate comparison between the observations made in different nuclear power plants and harmonize the reporting of generic ASSET results. The guidelines should always be used with a critical attitude and a view to possible improvements

    2008-01-01

    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.

  12. 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.

    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

    Full Text Available This articles aims to revise the traditional theory according to which the Mercurio Peruano newspaper was closed down by the Spanish colonial authorities in order to pre-empt the development of nationalist sentiment in Peru. Available primary sources not only reveal multiple inconsistencies in this theory, but clearly prove that the closure of this renowned newspaper could not have been the result of instructions received from metropolitan Spain, given that the authorities in Madrid were informed of its closure once it had already taken place.Este artículo tiene por objetivo revisar la visión tradicional de la clausura del Mercurio Peruano, que se venía atribuyendo a una Administración colonial deseosa de evitar el surgimiento de un protonacionalismo peruano. Contrastando la historiografía existente con las fuentes primarias disponibles, se evidencian las múltiples inconsistencias de dicha visión y se demuestra fehacientemente que el cierre del Mercurio Peruano no pudo ser el resultado de una decisión de las autoridades metropolitanas, que se enteraron de su cierre a posteriori.

    Full Text Available The Chilean regions have a history that dates back several decades since the first attempts to establish regionalization in the fifties, until the Regional Governments were installed in 1993. Nevertheless, the critical reading of the regionalization process and decentralization show that beyond many advances, we are still far from representing a country with a unitary decentralized state model. In this work, the most important milestones of the Chilean institutional development are revised at a regional scale, in order to establish the level of advance and the overdue challenges on this subject in the country.

    Las regiones chilenas tienen una historia que se remonta a varias décadas, desde los primeros intentos de establecer una regionalización en Chile en los años cincuenta, hasta la instalación de los denominados Gobiernos Regionales el año 1993. Sin embargo, la lectura crítica del proceso de regionalización y sobre todo de la descentralización, muestra que más allá de los innumerables avances, todavía estamos lejos de representar como país, un modelo de estado unitario desconcentrado. En este trabajo se revisan los hitos más importantes del desarrollo institucional chileno a la escala regional, con el fin de establecer el nivel de avance y los desafíos pendientes del país en esta materia.

    Full Text Available Si algo ha marcado al género operístico desde sus inicios ha sido el público que ha asistido a los espectáculos que se representaban en sus teatros. En el siglo XX, con la aparición del cine, la ópera sufre una crisis de audiencia, el público tiene un espectáculo masivo al que asistir, más económico y más cercano al consumo cultural dominante. La ópera pasa a convertirse en un espacio para una élite capaz de pagar los altos precios de los abonos. En la actualidad diversas decisiones tomadas por teatros de ópera están provocando que el interés por el género crezca en una sociedad posmoderna en la que la tecnología parece haber agotado los límites espaciales y temporales. Óperas con libretos basados en películas o en personajes de la contemporaneidad, que exhiben prodigios técnicos visuales y sonoros, realizados éstos por grandes figuras del arte y del diseño. Un concepto de la ópera que vuelve a ser un espectáculo que abarca todas las disciplinas, y que ha asumido la evolución que la tecnología ha aportado a éstas con total naturalidad.

Huntington (1993 describió esto como un choque de civilizaciones entre el islam y occidente, pero se argumenta que esto es una simplificación. Otros factores a tener en cuenta son la coexistencia de las sociedades modernas y postmodernas, la desigual distribución de la riqueza, los conflictos internacionales insolubles de larga duración y la condición del islam en diferentes países. Se discute el impacto de la futura diseminación de la tecnología de la información en la resolución de algunas de estas diferencias. Recientemente se han desmantelado anteriores redes internacionales e instituciones. Coexisten redes legales e ilegales de negocios y organizaciones. En el caso de las redes terroristas, es muy complicado identifcarlas, atacarlas y desactivarlas. En el proceso de combatir al terrorismo no deberían sacrificarse los derechos fundamentales democráticos.

    1980-05-01

    This paper presents a summary of the recently revised gas-cooled fast breeder reactor (GCFR) safety program plan. The activities under this plan are organized to support six lines of protection (LOPs) for protection of the public from postulated GCFR accidents. Each LOP provides an independent, sequential, quantifiable risk barrier between the public and the radiological hazards associated with postulated GCFR accidents. To implement a quantitative risk-based approach in identifying the important technology requirements for each LOP, frequency and consequence-limiting goals are allocated to each. To ensure that all necessary tasks are covered to achieve these goals, the program plan is broken into a work breakdown structure (WBS). Finally, the means by which the plan is being implemented are discussed

  13. Potentialities of Revised Quantum Electrodynamics

    Directory of Open Access Journals (Sweden)

    Lehnert B.

    2013-10-01

    Full Text Available The potentialities of a revised quantum electrodynamic theory (RQED earlier established by the author are reconsidered, also in respect to other fundamental theories such as those by Dirac and Higgs. The RQED theory is characterized by intrinsic linear symmetry breaking due to a nonzero divergence of the electric field strength in the vacuum state, as supported by the Zero Point Energy and the experimentally confirmed Casimir force. It includes the results of electron spin and antimatter by Dirac, as well as the rest mass of elementary particles predicted by Higgs in terms of spontaneous nonlinear symmetry breaking. It will here be put into doubt whether the approach by Higgs is the only theory which becomes necessary for explaining the particle rest masses. In addition, RQED theory leads to new results beyond those being available from the theories by Dirac, Higgs and the Standard Model, such as in applications to leptons and the photon.

    This Engineering Study revision evaluated the alternatives to provide tank waste characterization analytical samples for a time period as recommended by the Tank Waste Remediation Systems Program. The recommendation of storing 40 ml segment samples for a period of approximately 18 months (6 months past the approval date of the Tank Characterization Report) and then composite the core segment material in 125 ml containers for a period of five years. The study considers storage at 222-S facility. It was determined that the critical storage problem was in the hot cell area. The 40 ml sample container has enough material for approximately 3 times the required amount for a complete laboratory re-analysis. The final result is that 222-S can meet the sample archive storage requirements. During the 100% capture rate the capacity is exceeded in the hot cell area, but quick, inexpensive options are available to meet the requirements

    1999-04-01

    Full Text Available El objetivo general de este artículo es evaluar los efectos de la inseguridad ciudadana en el uso del espacio público. Dicha evaluación exige analizar dos relaciones que se establecen en el ámbito de la violencia: la relación entre victimización y percepción de inseguridad; y la que se establece entre actitudes sociales y resolución pacífica de conflictos nacionales. Para ello, se analizaron las variables victimización, percepción de inseguridad, uso del espacio físico, actitudes hacia el sistema institucional político y social y hacia la resolución de conflictos nacionales, y las posibles relaciones entre ellas. Los datos para realizar el estudio se obtuvieron por medio de una encuesta que se llevó a cabo con 1 200 personas de 18 y 70 años de edad residentes en la ciudad de Santiago. Los resultados indican que Santiago es una ciudad de habitantes con temor y que el aumento de la percepción de inseguridad de sus habitantes contrasta con el hecho de que las tasas de victimización se hayan mantenido, más o menos, constantes en los años que precedieron a la encuesta. El temor se relaciona con el abandono del espacio público físico y sociopolítico, así como con el refugio en los espacios y la vida privados. La actitud de resolver los conflictos por medios no pacíficos es frecuente y se asocia en mayor medida con la inseguridad, la actitud negativa hacia la democracia y la falta de expectativas sobre el futuro del país. Los resultados de este estudio respaldan la idea de que para superar el temor la gente tiende a adaptarse a la realidad adoptando una postura conformista, homogeneizando las creencias y los comportamientos, y sobreestimando la fuerza como medio para resolver las diferencias.

    John GLEDHILL

    2010-11-01

    Full Text Available El derecho a la vivienda es un derecho humano básico recogido en las declaraciones internacionales y muchas constituciones nacionales. Del él puede hacerse también una lectura “burguesa”, como fundamento de la democracia liberal basada en la propiedad privada, con interesantes consecuencias cuando los ciudadanos ven que sus derechos son violados. Este artículo explora cómo va cambiando la definición del derecho a la vivienda a través de la agenda de ONU–Hábitat, y discute los puntos fuertes y débiles de este programa desde una perspectiva antropológica. El análisis incide sobre el hecho de que gran parte de la población mundial ha tenido que encontrar sus propias soluciones a los problemas de vivienda, y aborda los debates en torno a la “regularización” de los asentamientos, la tierra y las viviendas “informales”, a los mercados de la vivienda, y a las implicaciones sociales de los diferentes enfoques al respecto. Se sostiene que el enfoque de las Naciones Unidas, a pesar de su énfasis en la planificación participativa y la universalización del derecho a la ciudad, sigue marginando aspectos más complejos que surgen de las relaciones entre la vivienda, el hábitat y los patrones de sociabilidad. El artículo concluye con la consideración de las condiciones a las que se enfrentan los movimientos sociales que luchan por el derecho a la ciudad, en un contexto de regeneración urbana y gentrificación basado en la clase social, incorporando la comprensión de los procesos microsociales que ofrece la investigación etnográfica, desde una perspectiva multidimensional, sobre las relaciones de poder que han estructurado el reciente desarrollo de las ciudades metropolitanas.

Realizamos la tesis profesional en el Hospital de niños de la Misericordia de Bogotá en el año 1950 (86, basada en el análisis de más de 300 enfermos de Mal de Pott tratados con pobres resultados en esa institución en la época prequimioterápica.

    Revision otologic surgery places a significant economic burden on patients and the healthcare system. We conducted a retrospective chart analysis to estimate the economic impact of revision canal-wall-down (CWD) mastoidectomy. We reviewed the medical records of all 189 adults who had undergone CWD mastoidectomy performed by the senior author between June 2006 and August 2011 at Loyola University Medical Center in Maywood, Ill. Institutional charges and collections for all patients were extrapolated to estimate the overall healthcare cost of revision surgery in Illinois and at the national level. Of the 189 CWD mastoidectomies, 89 were primary and 100 were revision procedures. The total charge for the revision cases was $2,783,700, and the net reimbursement (collections) was $846,289 (30.4%). Using Illinois Hospital Association data, we estimated that reimbursement for 387 revision CWD mastoidectomies that had been performed in fiscal year 2011 was nearly $3.3 million. By extrapolating our data to the national level, we estimated that 9,214 patients underwent revision CWD mastoidectomy in the United States during 2011, which cost the national healthcare system roughly $76 million, not including lost wages and productivity. Known causes of failed CWD mastoidectomies that often result in revision surgery include an inadequate meatoplasty, a facial ridge that is too high, residual diseased air cells, and recurrent cholesteatoma. A better understanding of these factors can reduce the need for revision surgery, which could have a positive impact on the economic strain related to this procedure at the local, state, and national levels.

    The surgery during which the cochlear implant internal device is implanted is not entirely free of risks and may produce problems that will require revision surgeries. To verify the indications for cochlear implantation revision surgery for the cochlear implant internal device, its effectiveness and its correlation with certain variables related to language and hearing. A retrospective study of patients under 18 years submitted to cochlear implant Surgery from 2004 to 2015 in a public hospital in Brazil. Data collected were: age at the time of implantation, gender, etiology of the hearing loss, audiological and oral language characteristics of each patient before and after Cochlear Implant surgery and any need for surgical revision and the reason for it. Two hundred and sixty-five surgeries were performed in 236 patients. Eight patients received a bilateral cochlear implant and 10 patients required revision surgery. Thirty-two surgeries were necessary for these 10 children (1 bilateral cochlear implant), of which 21 were revision surgeries. In 2 children, cochlear implant removal was necessary, without reimplantation, one with cochlear malformation due to incomplete partition type I and another due to trauma. With respect to the cause for revision surgery, of the 8 children who were successfully reimplanted, four had cochlear calcification following meningitis, one followed trauma, one exhibited a facial nerve malformation, one experienced a failure of the cochlear implant internal device and one revision surgery was necessary because the electrode was twisted. The incidence of the cochlear implant revision surgery was 4.23%. The period following the revision surgeries revealed an improvement in the subject's hearing and language performance, indicating that these surgeries are valid in most cases.

Therefore the revision certificate admits the written proof as on the basis of its conclusion of the inspector, the public prosecutor receives the information on a perfect crime, abusing, and also on the persons who have committed a crime, on the period of commission of crime and an amount of damage.

    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.

  11. Descriptor revision belief change through direct choice

    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.

  16. Revision of the DELFIC Particle Activity Module

    Energy Technology Data Exchange (ETDEWEB)

    Hooper, David A [ORNL; Jodoin, Vincent J [ORNL

    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.

    Full Text Available La ecología actual no es ya una ciencia puramente descriptiva y autosuficiente. Dada la naturaleza compleja de los ecosistemas, ha sido necesario recurrir a disciplinas como la física, la química, y a herramientas matemáticas como la teoría de catástrofes, la teoría de fractales, la cibernética y la teoría de redes, para el estudio y predicción de su comportamiento. La termodinámica -en sus distintos estadios -también aporta a esa visión pluralista, tal vez la única aproximada al comportamiento real de un ecosistema. Se presentan algunas ideas sobre la importancia que pueden tener conceptos como la energía, la entropía, la exergía, la información, el no equilibrio en el análisis de los procesos que tienen lugar en ecosistemas.

    Con motivo de haber sido distinguido para presentarme en este recinto respetable para recibir la medalla de Miembro Honorario, revisé la lista de los académicos honorarios y demás miembros de la Academia Nacional de Medicina. Que la persona, que les dirige la palabra, pase a engrosar la lista de figuras tan eminentes de la Medicina Colombiana, me causa sentimientos de temor, de humildad y de satisfacción.

    De temor porque soy consciente de lo que significa ser y de lo que se espera de un Miembro Honorario de la Academia. De humildad por figurar al lado de profesionales tan eminentes y que han hecho contribuciones tan significativas en todas la ramas de la Medicina. Y de satisfacción por haber sido elegido por unanimidad para pertenecer a esta casa, después de mas de treinta años de labor académica y de casi quince frente al Instituto Nacional de Medicina Legal y Ciencias Forenses.

    Me perdonarán ustedes, si de la lista de Académico Honorarios deseo mencionar en esta ocasión solamente el nombre del Doctor Carlos Sanmartín Barberi, cuya ausencia de esta sesión solemne es extremadamente dolorosa. Con Carlos tuvimos una larga y estrecha amistad que comenzó con los estudios en la Facultad de Medicina de la Universidad Nacional, cuyos cicuenta años de egresados como médicos, se celebró recientemente con un acto académico, en el cual, el Doctor Sanmartín deleitó a los asistentes con una disertación sobre los progresos de la Medicina durante los últimos cincuenta años, disertación profunda y amena como todas las que pronunció durante su vida académica y profesional.

    Full Text Available The Redwood highway, through the Californian forest, runs on a viaduct, as it crosses a mountain slope of about 45° inclination. The firm ground is fairly deep, and as an additional constructional difficulty, it was necessary to respect the natural beauty of the countryside. A structure of portal frames were built, forming a number of short spans. These spans were bridged with metal girders, on which a 19 m wide deck was placed. The columns are hollow and have a transversal cross beam, to join each pair. There was difficulty in excavating the foundations for the columns, as it was necessary to dig through the soft top soil, and also prevent this soil from hurting the trunks of the forest trees. Another significant difficulty in the construction of this viaduct was the access to the working site, since there were no suitable platforms from which to operate the appropriate machinery. This made it necessary to do a lot of the work by manual operation. As one of the edges of the deck is very close to the mountain side, a supporting beam was erected on this side. It was made of concrete, on metal piles. The formwork for the deck structure was placed on the concrete stems of the supporting piles.La autopista denominada Redwood (California salva, con un paso superior, la ladera de un bosque cuya pendiente es del 1/1.

Pocos estudios controlados tienen reportado valores de confiabilidad de tests de fuerza y a pesar de esta ser considerada buena en la mayoría de los estudios publicados (0,79 a 0,99, las diferencias entre el test y el re-test vienen siendo observadas como estadísticamente significativas. De esta forma, se sugiere la utilización de los valores de un segundo test, por lo menos, en estudios de pesquiza, de modo que las eventuales modificaciones de los valores de fuerza puedan ser atribuibles al efecto de los tratamientos realizados y no a simples adaptaciones al protocolo de test. Las relaciones entre los tests de fuerza máxima y los tests submáximos o las variables antropométricas han sido investigadas con la intención de predecir la fuerza máxima sin que el individuo tenga que ser sometido a un test de carga máxima, evitando riesgos de posibles lesiones. Los valores de carga máxima, o los porcentuales de esta son comunmente utilizados para prescribir mejor el entrenamiento. La predicción de una repetición máxima (1RM a través de test máximos parece buena (en general correlaciones > 0,90, entretanto, en la mayoría de los estudios revisados, las ecuaciones predictivas desarrolladas casi siempre no son aprobadas en el escrutiño de una validación cruzada.

    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.

Se concluye que la mayoría de los estudios publicados sobre la episiotomía fueron elaborados por médicos, con predominancia de los aspectos técnico-científicos como reflejo de una formación cartesiana, con enfoque biológico, también reflejo de una visión política para la salud de la mujer, que siempre la he definido como un ser reproductivo, creada para el lar y para los hijos, ideología impresa en los programas políticos que orientaron la salud en este grupo.Episiotomy is a surgical procedure conducted by obstetricians and obstetrical nurses on the female perineum at the time of delivery. This procedure is adopted as routine in obstetrics, and its practice is currently being questioned. The present study was conducted beginning with bibliographical research of the scientific production regarding episiotomy. The bibliographical research for the present study was done with the help of search tools at the LILACS database. 60 studies were found, of which 22 specific papers on episiotomy, referring to the 1980s, 1990s and the period from 2000 to 2005, were analyzed. Discussions on the subject matter dealt with the study characteristics, the professional conducting the procedure and the manner of study of this procedure. Research indicates the majority of studies on episiotomy were done by doctors, whose main concern appears to be the technical and scientific aspects of the subject matter. This reflects a Cartesian background with a biological focus, as well as a political vision of feminine health, as a rule considering women reproductive beings whose most relevant roles are those connected to domestic, child-rearing activities, all in.

    A review of the effects of wildfires on Mediterranean soils was carried out with special emphasis on the biogeochemical processes involved in soil C sequestration. Modifications to the composition and properties of soil humic substances and related resilient C-forms in soil resulting from fires were also discussed. The systematic effects of fires on soil organic matter (SOM mainly involve changes to its solubility and colloidal properties, selective thermal degradation, structural condensation and the cyclization of soil C and N-forms. These effects represent an increase in the biogeochemical stability and chemical diversity of the SOM after the thermal generation of structures that are not found in soils unless they are affected by fire. Non-systematic effects also depend on local environmental constraints and on the great differences in fire intensities and propagation patterns. The effects of fire were also discussed, taking advantage of the results of laboratory simulation experiments. This approach is indispensable for differentiating fire intrinsic effects on soil from those produced by fire-induced inputs of charred necromass and the subsequent effects of soil erosion. In some cases, the characteristic properties acquired by post-fire soils can be explained in terms of molecular-level features of humic substances and, in particular, those concerning resistance to biodegradation, cation exchange capacity, N-availability, soil water repellence and aggregate stability.

    Full Text Available El budismo plantea acceder a una visión de la realidad desligada de creencias y supuestos de todo tipo. Para conseguirlo plantea una indagación libre en referencia al enclaustramiento de nuestro pensar y sentir al que nos somete el ego. El ego con sus necesidades y deseos genera un acceso a la realidad relativo a nosotros. Lo que se propone es una liberación de esta lectura para que la realidad pueda aparecer frente a nosotros de manera independiente de las imposiciones del ego, es decir, un acceso a ella ab-soluto (suelto de nosotros. El budismo es, pues, una propuesta de ‘espiritualidad no religiosa’, para la que el mismo término espiritualidad  resultaría inadecuado porque en él subyace la creencia en el ‘espíritu’. Vemos que por todo ello el mensaje budista resulta muy apropiado para las sociedades hoy presentes, bien para aquellas que están transitando de una sociedad agrícola a una industrial, que conlleva a debilitar las convicciones religiosas hasta disolverlas; bien para aquellas que están próximas o han entrado ya en las sociedades llamadas de conocimiento, innovación y cambio continuo cuya condición de movilidad impide  las creencias, porque son fijadoras, lo que arrastra como consecuencia la imposibilidad de tener religión ni espiritualidad.

    An effective, state-of-the art secondary water chemistry control program is essential to maximize the availability and operating life of major PWR components. Furthermore, the costs related to maintaining secondary water chemistry will likely be less than the repair or replacement of steam generators or large turbine rotors, with resulting outages taken into account. The revised PWR secondary water chemistry guidelines in this report represent the latest field and laboratory data on steam generator corrosion phenomena.

    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.

  10. EPRI BWR Water Chemistry Guidelines Revision

    International Nuclear Information System (INIS)

    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

  15. EPRI PWR primary water chemistry guidelines revision

    International Nuclear Information System (INIS)

    McElrath, Joel; Fruzzetti, Keith

    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

  7. 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.

  8. A revised Self- and Family Management Framework.

    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.

  5. Nuclear safety guide: TID--7016, Revision 2

    International Nuclear Information System (INIS)

    Thomas, J.T.

    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. Revision 2 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 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

  6. 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

    2017-06-01

    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

Alguien recordó que la viuda formaba parte de algo que era como una institución. Al entierro la acompañaron no más de diez personas. Dos hijos varones con sus mujeres, una hija única con su marido, tres o cuatro nietos y un viejo que trabajosamente anduvo detrás del cortejo gesticulando y hablando solo y deteniéndose a veces para mirar algo a su espalda y limpiarse las lágrimas y el sudor de la cara y el cuello con un pañuelo floriado.

    Full Text Available Consideramos importante rescatar el trabajo colectivo y acumulado que precede y sucede a la labor de intermediación académica que realiza una revista. Para ello recordamos una clásica frase prologal: el texto que usted tiene en sus manos. Con cierta ironía, porque quizás muy pocos de los lectores puedan tener entre manos y oler el papel impreso de Chasqui. Desde sus pantallas, sus tablets o sus teléfonos la intención es que se comprenda este número como un solo cuerpo. Y al mismo tiempo, como un esfuerzo colectivo.

    Full Text Available Las dinámicas actuales de las sociedades modernas y postmodernas hacen que haya una constante creación y flujo de unidades léxicas cuyo origen se hace cada vez más difícil de identificar. Este documento se propone reportar una experiencia investigativa en el área de la lexicografía que se llevó a cabo en algunos pueblos de la región de Cundinamarca. A través de grabaciones de audio de conversaciones informales, entrevistas y cuestionarios se buscó elaborar un glosario de naturaleza dialectal. Las conclusiones indican que debido a la movilidad de los habitantes de la ciudad de Bogotá hacia los pueblos de Cundinamarca y viceversa, es difuso determinar un vocabulario específico.

    Full Text Available El reanálisis del Monumento 1 de Xkombec (Campeche, México, basado sobre su nueva documentación realizada en 2014 por los colaboradores del Proyecto Atlas Epigráfico de Yucatán, permite descartar la datación de esta inscripción en 866 d. C. y ubicarla a mediados del siglo VIII d. C., contemporánea de los monumentos de Xcalumkín y otros sitios cercanos del Puuc campechano. De acuerdo con el texto, la organización política de Xkombec era parecida a otros centros de Puuc. La ciudad contaba con su propia casa noble, cuyos miembros Xok Tun y B’ahlam eran de rango secundario y llevaban el título de b’ahkab y, probablemente, estaban relacionados con Xcalumkín. ENGLISH: Recent analysis of the epigraphy on Monument 1 from Xkombec indicates that the monument can be dated to A.D. 866, not to the mid-8th century as was previously argued. This new date marks Monument 1 as contemporary to the monuments at Xcalumkin and other neighboring Puuc sites. According to the text contained on Monument 1, political organization of Xkombec was similar to that of other Puuc centers. The association between these two centers may indicate that members of the noble house at Xkombec (Xok Tun and his son B’ahlam may have been related to the nobility of Xcalumkin.

    Full Text Available La oxitocina es el medicamento más comúnmente asociada con la prevención de complicaciones perinatales y recientemente fue incluida por el Instituto para la Administración Medicamentosa Segura (Institute for Safe Medication Practices - ISMP en una pequeña lista de medicamentos “con alto grado de riesgos”, lo que puede “necesitar salvaguardas especiales para reducir el riesgo de error”. Las recomendaciones actuales para administrar este medicamento son vagas en relación a la indicación, tiempo de uso, dosis y el monitoreo de los efectos maternos y fetales. Una revisión de los datos clínicos y farmacológicos disponibles sugiere que las orientaciones específicas y basadas en evidencias para administrar oxitocina durante el parto puede derivarse de datos disponibles. Si implementadas, estas prácticas pueden reducir la probabilidad de daños al paciente. Esto sugiere el foco de las orientaciones para la administración electiva limitada de oxitocina, considerar estrategias que disminuyan la necesidad de usar oxitocina, confiar en terapéuticas de bajas dosis de oxitocina, la adhesión a definiciones semicuantitativas específicas sobre parto adecuado e inadecuado, y la aceptación de que, una vez que la actividad uterina adecuada sea alcanzada, es generalmente preferible esperar más tiempo que aumentar la infusión de oxitocina. El uso de protocolos conservadores y específicos para monitorear los efectos de la oxitocina en la madre y en el bebé tiende no sólo a aumentar los resultados, mas también a reducir los conflictos entre miembros del equipo obstétrico. Implementar estas orientaciones parece ser apropiada en una cultura cada vez más focalizada en la seguridad del paciente.

Pertenece a un editorial publicado en Nature y fïrmado por Henry Gee, uno de sus comentaristas sobre evolución. El motivo de que una revista científica de las más prestigiosas (que se pueden considerar como las mantenedoras de la ortodoxia, haga suyo ese comentario es que las investigaciones más recientes (especialmente en el campo de la embriogénesis han revelado unos fenómenos que han puesto de manifiesto su absoluta incompatibilidad con la teoría darwinista de la evolución. Las consecuencias de esto son obvias, y las precisa otro editorialista de Nature, Philip Ball, en un comentario sobre la secuenciación del Genoma humano: «Los biólogos van a tener que construir una nueva Biología». Tenemos por delante un duro y largo trabajo científico por realizar, pero también tenemos una tarea previa: depurar la Biología de la, tan arraigada, terminología darwinista, cargada de conceptos y prejuicios deformadores de los fenómenos biológicos.

En este artículo se muestra lo que llamo «complicidad ciudadana» basada en lo que el Nuevo Servicio Público define como gobierno basado en la comunidad. Ellos no están reinventando ninguna clase de gobierno, lo que están haciendo es crear una nueva forma de gobierno en la que los ciudadanos prefieren tomar el mando que servir. El estudio del caso que muestro nos ayuda a entender cómo una mayor participación de los ciudadanos en las tareas de la administración local puede hacer disminuir visiblemente el poder del promotor en el desarrollo de una Nueva Ciudad. Esta complicidad ciudadana se traduce en términos de implicación de los miembros de la comunidad en el crecimiento y en el Gobierno de la ciudad. Clasificación JEL: H1, H11, H70.

    Full Text Available La comunicación afectiva con la persona discapacitada —como social y pedagógicamente se ha convenido en denominar— introduce un tipo de relación asentada en un principio de diferencia. Sin embargo, esta diferencia no es posible pensarla bajo un marco teórico que pretendiese dejar resueltas todas las contradicciones que semejante relación de alteridad implica. Pues se trata de un acontecimiento cargado de suficientes consecuencias en todos los aspectos como para requerir una reflexión narrativa en vez de un frío análisis conceptual. El presente artículo no ha podido ser escrito, por tanto, bajo el régimen de una escritura científica, pero tampoco se trata de un testimonio personal. Procurando evitar las posibles arrogancias derivadas de ambos planteamientos, lo que aquí se presenta es el diario de un aprendiz, de alguien que en su trato diario con la «discapacidad» ha ido descubriendo la singularidad de las emociones del otro y ha tenido que transformar la relación misma en un lenguaje que permitiese habitar la intimidad de una relación inquietante.

    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. 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

    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.

    2001-01-01

    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. Closed cooling water chemistry guidelines revision

    International Nuclear Information System (INIS)

    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)

    1984-01-01

    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

  5. Condiciones de posibilidad para una justicia global

    Pereira, Gustavo

    2004-06-01

    Full Text Available Recognition, as a constitutive part of subjectivity, is a basic need for people as well as for States. The terms of international relationships imposed by a great number of international credit and commerce institutions contradict and undermine such recognition, by means of policies that result in segregation and poverty in the poorest countries. Breaking such logic seems to be the way to enable the existence of conditions of global justice based on terms of reciprocal recognition. A prudential argument is the first step in this process; mid and long-term benefit would be the only rational motivation for international institutions to enable such an openness that would ensure reciprocal recognition. However, this argument is not sufficient, and the objective of a radical inclusion affecting all regions of the planet requires a moral argument based on the idea of equal dignity, inherent to every person. Global justice and its counterpart, local justice, will only be possible through the combination of these two arguments, which would make the existence of a logic of reciprocal recognition possible, thus enabling justice.

    El reconocimiento, en tanto que constitutivo de la subjetividad, es una necesidad básica tanto de las personas como de los Estados. Los términos de relación internacional impuestos por buena parte de los organismos internacionales de crédito y comercio niegan y socavan este reconocimiento a través de políticas que generan exclusión y pobreza en los países más pobres. La ruptura de esta lógica se presenta como un camino que posibilita el surgimiento de condiciones de justicia global basadas en términos de reconocimiento recíproco. Un argumento prudencial oficia como primer paso en este proceso, el beneficio a medio y largo plazo sería la motivación racional para que los organismos internacionales generasen una apertura que permitiese asegurar el reconocimiento recíproco. Sin embargo, este argumento no es

  8. Clinical and Economic Burden of Revision Knee Arthroplasty

    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.

    2018-01-01

    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.

    1983-01-01

    The restoration of the continuity of the urinary tract represents one of the major problems in rat renal transplantation. End-to-end ureterostomy is the most physiologically effective technique; however, it involves noteworthy technical difficulties because of the extremely thin caliber of the ureter in the rat and the high incidence of postoperative hydronephrosis. We describe a new technique for end-to-end ureterostomy in the rat, where the use of an absorbable ureteral stent is recommended. A 5-0 plain catgut thread is used as a stent. The anastomosis is performed under an operating microscope at X 25-40 magnification with interrupted sutures of 11-0 Vicryl. The use of the indwelling stent facilitates the performance of the anastomosis and yields optimal results. The macroscopical, radiological, and histological controls in a group of rats operated on with this technique showed a very high percentage of success with no complications, a result undoubtedly superior to that obtained with conventional methods.

    Although excessive fructose intake is epidemiologically linked with dyslipidemia, obesity, and diabetes, the mechanisms regulating plasma fructose are not well known. Cells transfected with sodium/glucose cotransporter 5 (SGLT5), which is expressed exclusively in the kidney, transport fructose in vitro; however, the physiological role of this transporter in fructose metabolism remains unclear. To determine whether SGLT5 functions as a fructose transporter in vivo, we established a line of mice lacking the gene encoding SGLT5. Sodium-dependent fructose uptake disappeared in renal brush border membrane vesicles from SGLT5-deficient mice, and the increased urinary fructose in SGLT5-deficient mice indicated that SGLT5 was the major fructose reabsorption transporter in the kidney. From this, we hypothesized that urinary fructose excretion induced by SGLT5 deficiency would ameliorate fructose-induced hepatic steatosis. To test this hypothesis we compared SGLT5-deficient mice with wild-type mice under conditions of long-term fructose consumption. Paradoxically, however, fructose-induced hepatic steatosis was exacerbated in the SGLT5-deficient mice, and the massive urinary fructose excretion was accompanied by reduced levels of plasma triglycerides and epididymal fat but fasting hyperinsulinemia compared with fructose-fed wild-type mice. There was no difference in food consumption, water intake, or plasma fructose between the two types of mice. No compensatory effect by other transporters reportedly involved in fructose uptake in the liver and kidney were indicated at the mRNA level. These surprising findings indicated a previously unrecognized link through SGLT5 between renal fructose reabsorption and hepatic lipid metabolism. PMID:23451068

    2018-05-01

    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.

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

    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.

  16. 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.

  17. 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

    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.

    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.

    Full Text Available En este artículo mis reflexiones las centro en el amor y la educación como fundamentos de la escuela inclusiva. Un amor sin adjetivos, basado en el respeto al otro como legítimo otro en la convivencia. Es un modo de vida que se inicia en la confianza desde la edad más temprana. Más aun, el amor es un acto de confianza. La confianza es el fundamento de nuestra convivencia. Los seres humanos nos enfermamos en un ambiente de desconfianza, manipulación e instrumentalización de las relaciones. La ausencia de amor nos deshumaniza. Vivimos en un mundo en el que se habla mucho del amor pero lo negamos, continuamente, en nuestros comportamientos y acciones. Vivimos inmersos en la cultura patriarcal. El amor, en dicha cultura, es considerado como un bien inalcanzable o, acaso, una ilusión o una esperanza. Sin embargo, debemos recuperar la vida matrística de la infancia, viviendo en el amor, amando. Es decir, respetando a las personas como legítimas personas en su diferencia, independientemente del hándicap, del género, de la etnia, religión o procedencia, en la convivencia. Sólo en el respeto y en el reconocimiento de las personas como personas radica el sentido de lo humano. Lo que constituye al ser humano como tal es la dimensión social y no lo genético. La genética es la condición inicial, es un punto de partida, no de llegada. Somos lo que somos gracias a las oportunidades que hemos tenido y no a los genes. Ahora bien, lo más humano del ser humano es desvivirse por otro ser humano y en este desvivir surge el valor ético de la educación. Por tanto, hablar de inclusión es hablar de justicia y, parece lógico, que para construir una sociedad justa sea necesario desarrollar modelos educativos equitativos que afronten con justicia los desequilibrios existentes en la misma. Para ello es imprescindible que los responsables de las políticas educativas, el profesorado y los investigadores contraigamos el compromiso moral de orientar el

    Full Text Available È possibile operare una forma di epoché sui concetti di carattere teologico? Ed è possibile riflettere sulla loro importanza, prescindendo dalla loro portata religiosa? I concetti teologici riescono a dirci qualcosa, se si trascura il loro riferimento essenziale alla nostra relazione con un essere divino? La risposta a queste domande consente di comprendere che cosa significhi essere un studioso laico della filosofia medievale, mentre è impossibile discutere tale problema senza prendere in considerazione anche la teologia medievale. Tutto ciò dunque riguarda non solo la natura della teologia, ma anche l’idea stessa di laicità. Dunque una storiografia del pensiero medievale pienamente consapevole di se stessa deve studiare il discorso teologico e affrontare in profondità la portata teorica di questo problema. Si può concludere che per una lettura laica della teologia medievale è paradossalmente essenziale cogliere proprio il senso intimo del pensiero religioso e le forme storicamente determinate della sua effettiva concettualizzazione.  Is some form of epoché possible on theological concepts? In which way? Is it possible consider their importance leaving their religious scope aside? Can the theological concepts tell us something unless we consider their essential reference to our relationship with a divine being? The answer to these questions let us to understand what means to be a secular (laico scholar of medieval philosophy. It's impossible conversely to discuss this problem without dealing with medieval theology. And this concerns not only the nature of theology, but also and deeply the same idea of secularism (laicità. Therefore a fully aware historiography of medieval thought has to understand the theological speech and to encounter the depth of this theoretical question. So we can conclude that for a secular reading of the medieval theology is paradoxically essential to catch the intimate sense of religious thought and the

    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.

Las posiciones y disposiciones en el campo del arte han quedado así reducidas a las proporciones justas: los valores estéticos no son puramente estéticos, sino que responden a una búsqueda de prestigio, o a convicciones morales, o a intereses de poder económico y político.

    La relación que existe entre el crecimiento poblacional y la situación socio-economica de una región, país o continente es algo que en forma intuitiva y vaga se conoce desde la más
    remota antigüedad. No menos conocido, en cada familia, ha sido el efecto nocivo de una
    reproducción superior a la deseada.
    Se ha necesitado del perfeccionismo de nuestros demógrafos y estadísticos para oscurecer la cuestión debajo y detrás de montañas de datos y de complejas ecuaciones.

    La generalizada y muy frecuente práctica del infanticidio entre tantos pueblos primitivos
    de ayer y de hoy, demuestra que a pesar de la elevada mortalidad natural, uno de los pocos insumos sobrantes del que se puede, cuando no se debe, disponer con facilidad es la vida humana acabada de nacer. Los superficiales ritos propiciatorios utilizados en algunos
    casos para su eliminación, le dan un escaso barniz religioso a la profunda preocupación
    ecológica y por consiguiente demográfica que los subyace.

    El infanticidio por simple abandono, practicado sin reatos de conciencia en la China Imperial el Imperio Romano o la Inglaterra pre-victoriana tenia una clara etiología social y económica. Los multitudinarios sacrificios juveniles de los Aztecas en un altiplano altamente erosionado por sobrecultivo, como el que encontraron los españoles a su llegada, parece no tener otra explicación razonable que el de ser una desesperada solución a un grave desequilibrio ecológico. Un desequilibrio que corrigió rápidamente la mortalidad mucho más eficiente que introducir los microbios europeos transportados por los conquistadores...

    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.

    Science.gov (United States)

    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.

    2004-12-01

    Full Text Available El reconocimiento de las expresiones del sexismo comporta un desafío educativo en la medida que la educación debe contribuir a su superación. La tarea es compleja pues la educación es parte de un proyecto global y, por ende, es imposible separarla del contexto social en el que se inserta. Sin embargo, los cambios operados en las últimas décadas en la condición de las mujeres, así como la inclusión de la equidad en la agenda nacional e internacional, obligan a un replanteamiento del devenir de los sistemas educativos. Es en este sentido que las actitudes y las creencias de los y las docentes deben ser revisadas con el fin de que (re descubran el carácter construido de lo considerado como natural para que así visualicen las desigualdades que encubren estas naturalizaciones. La herramienta analítica que provee esta reconstrucción, es la categoría del género en la medida que constituye una nueva veta teórica en la explicación de la desigualdad de las mujeres. The acknowledgement of the expressions of sexism implies an educative challenge as education must contribute to its improvement. The task is complex because education is part of a global project and, therefore, it is impossible to separate from the social context to which it belongs. Nevertheless, the changes performed during the last decades in the condition of women in general, as well as the addition of gender equity in the national and international agenda, force a new planning of the future development of education systems. Is in this sense that the attitudes and beliefs of the teachers must be revised with the purpose of (rediscovering the constructed disposition of what is considered as natural, so that they may see the inequities that cover these “natural” attitudes. The analytical tool provides this reconstruction is the gender category, as long as it constitutes a new theoretical vein in the explanation of female inequity.

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available In questo articolo si analizza il testo drammaturgico Pantani di Marco Martinelli, una veglia epica teatrale di uno dei più noti eroi dello sport italiano degli ultimi anni. Il dramma rilegge anche la storia di Pantani e ricostruisce gli strani avvenimenti che portarono alla sospensione, alla estromissione del ciclista dal Giro d’Italia nel 1999, e in seguito alla sua profonda crisi psicologica e tragica morte in solitudine in un hotel, a soli 34 anni. Oltre alle modalità proprie della veglia rituale, il dramma utilizza anche i metodi del processo giudiziario, e offre testimonianze dettagliate che conducono a una riflessione critica sulla società italiana negli anni del potere politico di Berlusconi e della sua filosofia del consumismo. I tre diversi generi della retorica classica (epidittico, giudiziario e deliberativo si mescolano in questa complessa tessitura teatrale. Coniugando informazioni (processo e rito (veglia, Martinelli riesce a fondere la tragedia greca (forma mimetica e corale e il moderno teatro di narrazione (forma diegetica monologante. Combinando assieme scene intensamente drammatiche, ricordi di imprese sportive epiche, passaggi giocosi e parodici, e giustapponendo vari stili e registri (giornalistico, lirico, parodico, elegiaco, Martinelli crea momenti di forte “straniamento” e sorpresa, e rende particolarmente efficace il rito funebre, la ricostruzione storica della tragica vicenda di Pantani e la critica all’ideologia che ha dominato l’Italia negli anni di Berlusconi.

  12. [The Use of Jumbo Cups in Revision Total Hip Arthroplasty].

    Science.gov (United States)

    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.

    The purpose of this study was to evaluate patient, operative, implant, surgeon, and hospital factors associated with aseptic revision after primary THA in patients registered in a large US Total Joint Replacement Registry. 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.

    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.

  18. 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

    Thirteen patients (14 hips) underwent revision from conventional cemented total hip arthroplasty to uncemented acetabular threaded screw-in components and cementless femoral press-fit stems by means of the Autophor, Biofit, and Ti-Thread designs. The patients suffered from all forms of primary hip disease except rheumatoid arthritis; their average age was 34 years. The average preoperative Harris hip score was 39.4; the average postoperative score was 71.2 at six months, 90.6 at one year, and 91.6 at two years. Complications included two femoral shaft fractures, one femoral nerve palsy, and one dislocation. No signs have been observed of loosening or migration as of an early (6-24 months) follow-up.

    Safe, efficient operation of waste tank farm facilities is dependent in part upon the availability of accurate, up-to-date plant drawings. Accurate plant drawings are also required in support of facility upgrades and future engineering remediation projects. This supporting document establishes the procedure for performing a visual field verification of engineering drawings, the degree of visual observation being performed and documenting the results. A copy of the drawing attesting to the degree of visual observation will be paginated into the released Engineering Change Notice (ECN) documenting the field verification for future retrieval and reference. All waste tank farm essential and support drawings within the scope of this program will be converted from manual to computer aided drafting (CAD) drawings. A permanent reference to the field verification status will be placed along the right border of the CAD-converted drawing, referencing the revision level, at which the visual verification was performed and documented

    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.

  6. 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.

  7. Revised spatially distributed global livestock emissions

    Asrar, G.; Wolf, J.; West, T. O.

    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.

  8. CUSTOMIZED ACETABULAR COMPONENTS IN REVISION HIP ARTHROPLASTY

    Directory of Open Access Journals (Sweden)

    G. M. Kavalersky

    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

  9. 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

    Full Text Available El propio Benjamin nos dice que leer el trabajo de Simmel sobre el concepto de verdad en Goethe le ayudó a comprender que el concepto de origen propuesto en su libro sobre el Trauerspiel era una transposición del concepto goethiano de fenómeno original. Para discutir cómo los hechos económicos pueden convertirse en fenómenos originales, Benjamin se sirve de una analogía con el concepto de Goethe de la metamorfosis de las plantas. Por eso, aquí, intentaremos demostrar que comprender lo que es la filosofía en Benjamin implica una experiencia de umbral –en forma de salto, discontinuidad, interrupción, renuncia, disipación, obediencia y metamorfosis– cuya formulación suprema, concisa y enigmática es la siguiente: “El método es un desvio” [Methode is Umweg]. Algunos elementos del pensamiento morfológico de Goethe permitirán establecer una constelación de afinidades, algo bastante útil para la interpretación de este enigma.

    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

    Fraile Suari, A; Gil González, S; Pérez Prieto, D; León García, A; Mestre Cortadellas, C; Tey Pons, M; Marqués López, F

    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.

    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.

    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.

  18. 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

  19. 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

    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

En este trabajo proponemos un modelo matemático para el transporte y acumulación de una toxina a través de una cadena alimentaria. El modelo se plantea mediante un sistema rígido de ecuaciones diferenciales que describen la dinámica. Se analiza la estabilidad local de la solución de equilibrio. Se discuten diferentes escenarios de aparición de brotes de una toxina a partir de simulaciones numéricas obtenidas mediante un esquema de discretización que combina un método de Runge-Kutta de tercer orden y la regla del trapecio, evitando la rigidez del sistema. Los resultados muestran que el tiempo que tarda en desaparecer la toxina en la red trófica depende del estado en que se encuentra la dinámica poblacional al momento del brote. Esta información puede emplearse para establecer un tiempo de veda en la pesca de tal manera que la toxina se reduzca a niveles inocuos para la salud humana.

    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.

  7. 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.

    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

    Lehnert B.

    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.

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.

    Full Text Available The Neotropical Sasoninae Neodiplothele Mello-Leitão, 1917 is revised and now includes eight species. 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.

Si estende così il costrutto di William Mitchell dalla città al patrimonio culturale precisando, anche attraverso alcune esemplificazioni, come le Smart IT modifichino profondamente le modalità di trasmissione, acquisizione e produzione della conoscenza trasformando quest’ultima in un fattore di sviluppo economico, sociale e culturale. Non secondariamente esse contribuiscono alla soluzione di problemi tipici dei processi connessi al lifecycle dei beni culturali: la loro conservazione, fruizione, comunicazione e gestione, nonché quelli connessi alla grande quantità di dati e alla loro eterogeneità. Infine, i nuovi sistemi come l’Internet of Things o il fenomeno dello User Generated Content permettono di concepire i beni culturali come ‘smart cultural objects’ e la generazione di conoscenza da parte degli utenti. Tutto ciò, se da una parte amplifica le possibilità di interazione tra soggetti e oggetti della conoscenza, dall’altra ne modifica radicalmente le modalità. Questo deve sollecitare le Università, le Istituzioni culturali e le Imprese a collaborare, nel prossimo futuro, sugli usi possibili delle soluzioni tecnologiche prospettate, in vista dell’affermazione di una più consapevole e partecipata cultura della sostenibilità del nostro patrimonio culturale.EnThis contribution takes the concept of ' Smart City ' as a paradigm in order to underline the importance of first and second generation of Information Technology (IT for the purpose of improving the competitiveness of a city, especially for what concerns its Cultural Heritage (CH.

    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....

    These examination standards are intended to assist NRC examiners and facility licensees to better understand the processes associated with initial and requalification examinations. The standards also ensure the equitable and consistent administration of examinations for all applicants. These standards are for guidance purposes and are not a substitute for the operator licensing regulations (i.e., 10 CFR Part 55), and they are subject to revision or other changes in internal operator licensing policy. This interim revision permits facility licensees to prepare their initial operator licensing examinations on a voluntary basis pending an amendment to 10 CFR Part 55 that will require facility participation.

En España, uno de los países más afectados por la larga crisis, la prosperidad anterior enseguida pareció ser un espejismo. Pero la crisis no ha afectado a todo el mundo en la misma medida. De hecho, hay gente que se ha enriquecido durante el período 2008-2012, en cambio, la crisis está teniendo un impacto mayor sobre los que ya se encontraba en una situación más precaria. En este artículo discutiré una de las múltiples caras de la crisis española que está afectando a los más desaventajados: los desahucios y su resistencia por parte de la población migrante. Para hacer esto, primero examinaré un municipio que ha sido paradigmático de enclave migrante en España: Salt. Salt es un municipio conocido en Girona, Catalunya, por haber sido descrito en los medios de comunicación como un gueto como resultado de los problemas que surgen con el exceso de inmigración (el 42% de su población es de origen extranjero. Salt se hizo famoso cuando en marzo de 2010 un grupo de vecinos entró en el ayuntamiento exigiendo más seguridad y denunciando la pasividad de la policía ante una ola de robos en el pueblo.

    Myers, L.B.; Bell, A.J.

    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

    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.

    Full Text Available Esta oración compuesta, palabras pronunciadas por don Quijote* en el segundo capítulo de la segunda parte de la novela cervantina, "Si a ti te mantearon una vez, a mí me han molido ciento", solo en aparencia un periodo hipotético, representa en realidad un conjunto paratáctico de dos unidades contrapuestas en su significado. Suscitan nuestro interés por hallarse en el mismo período los dos paradigmas del pretérito español que llamaremos pretérito simple y préterito compuesto. Es sabido cuán variada es la denominación de estos dos paradigmas verbales en las gramáticas y en los tratádos españoles. Seguiremos la nomenclatura del francés: se prefiere, en cuanto sea posible, dejar a parte el contenido limitándose a la forma.

    Full Text Available Riassunto Il focus che presento propone una riflessione interdisciplinare sul campo semantico del termine cambiamento. Lo scopo è quello di cogliere, attraverso uno sguardo sulla complessità del reale, alcune delle situazioni e alcuni processi dove la parola cambiamento si va a collocare. Come sappiamo il cambiamento lo possiamo ritrovare sia nei processi evolutivi, come in quelli formativi, o in quelli epistemologici, si pensi ad esempio al cambio di paradigma più famoso nella conoscenza umana: il passaggio dal sistema di pensiero geocentrico al sistema eliocentrico. Così, al cambiamento troviamo associati lo spaesamento, le resistenze, la crisi, la rabbia, la tristezza, ma non ultimo, l’ampliamento dei propri orizzonti di crescita personale e collettiva. Parole chiave: paradigma, organizzazione, relazione, esperienze di vita.An interdisciplinary reflection on the term changeAbstract My presentation proposes an interdisciplinary reflection on the semantic field of the word change. While looking at the complexity of reality, it aims at grasping some situations and processes where the term change is involved. As we know, we can find changes in evolutionary, educational, epistemological processes, let us think for example of the most famous paradigm change of human knowledge: the passage from geocentric to heliocentric mindset. Bewilderment, resistances, crisis, anger, sadness are thus associated to change, as well as the enlargement of one’s own personal and collective growth.Key word : paradigm, organization, relationship, life experiences.

    Full Text Available El desarrollo de las teorías del Sujeto modificó, de manera sensible, las estrategias de construcción del concepto de Institución y por tanto impuso la necesidad de reconsiderar a uno de los pilares en los cuales se fundamenta el saber de las Ciencias Sociales. Tales teorías, articuladas de manera indisoluble con los problemas del orden simbólico y por tanto con el problema del sentido, no han conducido sinembargo, a viabilizar satisfactoriamente un concepto dinámico de la institución como acción en y por la creación, manteniendo por el contrario afianzada su condición de entidad y estado de cosas. Una aproximación a la lógica del sentido, muestra por el contrario interesantes posibilidades, a la luz de las cuales ciertos debates sobre lo instituído y lo instituyente como momentos de la institución se revelan irrelevantes.

Some of these changes are mathematical, others are philosophical, and others are historical in character. This retrospective of the concept of number ‘one’ implies that the history of mathematics is much more complex and rich than that which is suggested by our intuition when we limit ourselves to a unique, lineal and continuous mathematics.

Se trata de un matrimonio con dificultades para disciplinar a sus tres hijos varones de ocho, seis, y cuatro años. En primer lugar, se exponen los principios teóricos y metodológicos, para luego mostrar la aplicación de ellos en el proceso vivido por la familia. Se aplica el modelo de intervención estructural, que busca que la misma familia logre realizar, paso a paso, los cambios requeridos en la dinámica y estructura familiar. En la situación específica de esta familia, se observa el fortalecimiento de la pareja como tal y como madre y padre en la medida que van logrando asumir la autoridad en forma compartida para disciplinar a los hijos. Al compartir esta experiencia, la autora pretende estimular a profesionales en Orientación a asumir el reto de considerar a las familias de la comunidad estudiantil, de las instituciones educativas donde laboran, como parte importante en el quehacer orientador.

    2014-01-01

    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).

  2. 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.

  3. 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.

  4. Systematic revision of the Phorusrhacidae (Aves: Ralliformes

    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.

    Full Text Available The aim of this paper is to revise some of the controversies around the meaning of the concept of development as well as to analyze the practical implications of the androcentric bias that inform its historical and political construction. We present the main feminist critiques to the theory and practice of development in the context of the crisis provoked by two main corrections to the concept: sustainability and the focus on human capacities. Different approaches have maintained the need of rethinking development from ecological constrictions, human needs or capacities and, finally, from the point of view of gender equality. Our tentative proposal is to initiate an exploration of this unstable conjunction in order to contribute to the construction of an ecofeminist theory of justice.

    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

    Full Text Available El creciente énfasis en el desarrollo de habilidades de investigación posiciona la presentación e interpretación de los datos como actividades cada vez más importantes. Tener competencia en interpretar representaciones de datos es esencial para comprender el mundo actual y ser un ciudadano científicamente alfabetizado. La tabla es usada cotidianamente, pero no es simple comprender los diferentes procesos cognitivos que activan las tablas. En el caso de las tablas es importante saber leerlas, completarlas, construirlas e interpretarlas. Existe controversia sobre qué enseñar primero respecto a cómo graficar; sin embargo, no existe controversia de qué enseñar respecto a las tablas. Debido a las dificultades de los sujetos con las tablas, la investigación en torno a ellas es un aporte al currículo científico escolar y a las prácticas de enseñanza y aprendizaje. Este artículo presenta el estado del arte sobre las tablas desde 1977 a 2012; la búsqueda y lectura de material bibliográfico del área de estadística referida a las tablas incluyó artículos científicos, libros, ponencias en congresos internacionales, tesis y currículo escolar de algunos países. Este estudio muestra la simplicidad aparente de las tablas, realiza una propuesta de estructura de tabla genérica, y entrega argumentos y lineamientos para que las tablas sean enseñadas explícitamente dadas su amplia inserción en nuestra cultura. The growing emphasis on the development of research abilities positions the presentation and interpretation of data as activities of increasing importance. Being competent in interpreting data representations is essential to understanding the modern world and to being a scientifically literate citizen.

    Full Text Available Las primeras décadas del siglo XX comienzan a mostrarnos la postal que detona el gran paradigma metropolitano del siglo: Nueva York y la altura de sus edificaciones, una ruptura total con el concepto de ciudad conocido por los europeos, al tiempo que la distopía nace como crítica literaria a la revolución rusa y derivará en imágenes de ciencia ficción producidas por el rascacielos que llevarán al urbanismo a nuevos niveles de planificación. Una visión tridimensional de la ciudad más allá del plano, al tiempo que el cine comienza a convertir el rascacielos en un personaje central de la narración visual. Progresivamente, las visiones de una sociedad futurista, mecanizada y alienante solo son posibles en una ciudad densamente verticalizada. Una imagen precisa, diseñada por Moses King, una ficción visual de 1911 que visionaba cómo sería la metrópolis de Nueva York en un futuro próximo, permite hacer una revisión sobre el paradigma de ciudad de rascacielos, y la evolución real de la metrópolis producto del fenómeno de verticalización producido por el rascacielos y la conquista de la altura.

    2014-01-01

    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

    Full Text Available En este trabajo se obtiene explícitamente el valor de una opción europea sobre una obligación que reparte cupones. Se supone que la estructura temporal de los tantos de interés viene determinada por el valor del tanto de interés instantáneo, el cual es una combinación lineal de n variables de estado. Estos factores son procesos estocásticos de tipo Ornstein-Uhlenbeck independientes y los precios del riesgo de mercado también son estocásticos. En primer lugar, aplicando un resultado de Friedman (1975 se resuelve de forma cerrada una ecuación general de valoración de activos derivados del tanto de interés. Posteriormente, se aplica al caso particular de la valoración de opciones sobre obligaciones que no reparten cupones y finalmente se obtiene el valor de las opciones sobre obligaciones que sí reparten cupones. Langetieg (1980 realizó un estudio con este modelo, pero con precios de riesgo de mercado constantes, utilizando otros procedimientos. Este trabajo supone una generalización de Jamshidian (1989, el cual obtuvo el valor de las opciones sobre obligaciones que reparten cupones para un modelo unifactorial.

    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

  20. 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

  3. Una defensa de la preferencia revelada

    2008-04-01

    Full Text Available The paper defends revealed preference analysis against the attack of Dan Hausman that RPA is unclear and has not empirical advantages. RPA is consistent with externalist accounts of the theory of mind where preference is interpreted and gets its meaning through our understanding of the actions of those studied. The paper argues that Hausman assumes the conclusion he is maintaining by assuming preference means “desire”. RPA is unavoidable in empirical research where we interpret outcomes through the intentional actions of human beings and is especially important in aggregate-data analysis. One of the confusions of philosophical critiques of RPA is to treat aggregate “type” explanations as though they refer to each token individual within the type. It concludes with some thoughts on the ethical considerations of using RPA.

    En este artículo se defiende el análisis mediante preferencias reveladas (APR de los ataques de Dan Hausman, para quien dicho análisis no es claro ni proporciona ventaja empírica alguna. El APR es compatible con las versiones externistas de la filosofía de la mente, para las que la preferencia se interpreta, y obtiene su significado, mediante la comprensión de las acciones de los sujetos estudiados. En el artículo se sostiene que Hausman defiende su conclusión porque supone que preferencia significa “deseo”. En el análisis empírico el APR es inevitable, dado que los resultados se interpretan a través de la acción intencional de los seres humanos. Asimismo, es especialmente importante en el análisis de datos agregados. Una de las confusiones de la crítica filosófica del APR consiste en tratar las explicaciones de “tipos” como si se refirieran a cada caso individual dentro de un tipo. El artículo finaliza con algunas reflexiones sobre cuestiones éticas del uso del APR.

    La tuberculosi és una afecció més pròpia de localitzar-se als pulmons, a través del contagi per via aèria, que no pas fora d'ells. La que es produeix als ronyons seria només un 3% i la infecció estaria vinculada a la disseminació per via sanguínia i limfàtica de la tuberculosi pulmonar. Si considerem que la tuberculosi es diagnostica principalment a l'adolescència, trobarem força peculiar el cas d'una nena que va desenvolupar una tuberculosi renal amb tretze mesos de vida.

  5. Las revoluciones de Thomas Kuhn, una mirada discontinuista

    Directory of Open Access Journals (Sweden)

    Pablo Melogno

    Full Text Available Resumen Se discuten algunas divergencias entre La revolución copernicana (1957 y La estructura de las revoluciones científicas (1962, de Thomas Kuhn. Se muestra que presentan una consideración diferente de los factores extracientíficos, que tienen en la primera un peso explicativo mayor. Se propone que en 1957 Kuhn maneja una historiografía casuística, centrada en la revolución copernicana, y en 1962 una historiografía estructural, centrada en los rasgos invariantes de las revoluciones científicas. Se concluye que las diferencias entre las dos obras son lo suficientemente profundas como para no considerarlas expresión de una misma visión de la ciencia.

  15. Anomalies of Nuclear Criticality, Revision 6

    International Nuclear Information System (INIS)

    Clayton, E.D.; Prichard, Andrew W.; Durst, Bonita E.; Erickson, David; Puigh, Raymond J.

    2010-01-01

    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

    2015-01-01

    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.

  20. UNA POLÍTICA ALIMENTARIA PARA TIEMPOS DE CRISIS

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Este artículo revisa el concepto de seguridad alimentaria. A partir de éste sugiere que es necesario considerar tanto la producción como el acceso a los alimentos como parte de una misma estrategia. Esto requiere implicar y al mismo tiempo fortalecer las capacidades nacionales, regionales y de las comunidades locales, prio-rizar el potencial de las comunidades, los agricultores y los ciudadanos de construir y apropiarse de las políticas alimentarias y de manera señalada la promoción a redes locales y regionales de productores de alimentos y consumidores. Argumenta que el propósito de entrecruzar en vez de confrontar el discurso de la seguridad alimen-taria y de la soberanía es una de las vías para avanzar en la discusión. Asimismo, argumenta que el significado de una política alimentaria en tiempos de crisis parte de la necesidad de enfrentar la desarticulación productiva y la desintegración social prevalecientes en el medio rural con una estrategia de reconstrucción institucional basada en la autonomía de los habitantes rurales y en una dinámica de intervencio-nes estatales a partir de una elaboración institucional inteligente capaz de aprender y adaptarse a las situaciones heterogéneas y cambiantes en el ámbito rural.
