    General conditions about the metallo thermic reduction in small bombs (250 and 800 gr. of uranium) has been investigated. Factors such as kind and granulometry of the magnesium used, magnesium excess and preheating temperature, which affect yields and metal quality have been considered. magnesium excess increased yields in a 15% in the small bomb, about the preheating temperature, there is a range between which yields and metal quality does not change. All tests have been made with graphite linings. (Author) 18 refs.

    The Plio-Pleistocene Llancanelo volcanic field is located in the south-eastern region of the province of Mendoza, Argentina. This wide back-arc lava plateau, with hundreds of monogenetic pyroclastic cones, covers a large area behind the active Andean volcanic arc. Here we focus on the northern Llancanelo volcanic field, particularly in Las Bombas volcano. Las Bombas volcano is an eroded, but still recognizable, scoria cone located in a circular depression surrounded by a basaltic lava flow, suggesting that Las Bombas volcano was there when the lava flow field formed and, therefore, the lava flow engulfed it completely. While this explanation seems reasonable, the common presence of similar landforms in this part of the field justifies the need to establish correctly the stratigraphic relationship between lava flow fields and these circular depressions. The main purpose of this research is to investigate Las Bombas volcano 3D subsurface architecture by means of geophysical methods. We carried out a paleomagnetic study and detailed topographic, magnetic and gravimetric land surveys. Magnetic anomalies of normal and reverse polarity and paleomagnetic results point to the occurrence of two different volcanic episodes. A circular low Bouguer anomaly was detected beneath Las Bombas scoria cone indicating the existence of a mass deficit. A 3D forward gravity model was constructed, which suggests that the mass deficit would be related to the presence of fracture zones below Las Bombas volcano cone, due to sudden degassing of younger magma beneath it, or to a single phreatomagmatic explosion. Our results provide new and detailed information about Las Bombas volcano subsurface architecture.

En América Latina la investigación urbana fue, en primer lugar, investigación sobre la gr ciudad y los fenómenos resultantes del actual proceso de urbanización. Por lo tanto es escasa la información disponible para el estudio de estos emprendimientos en ciudades de menor tamaño. A través de la bibliografía se puede observar que las ur ciones cerradas adquieren una especificidad propia en las ciudades intermedias. ubican en la periferia de las ciudades, cercanas a espacios verdes con buenas condiciones ambientales y paisajísticas. Impulsan el desarrollo y/o mejora de l infraestructura de servicios. Modifican los procesos de segregación social y fragmentación espacial, acorde a los actuales procesos urbanos. Las barreras físicas se convierten en barreras sociales y marcan profundas diferencias entre quienes viven adent y quienes viven afuera. Finalmente, estas urbanizaciones ocupan superficies pe ueñas en comparación con las extensiones ocupadas por los emprendimientos construidos en las grandes ciudades, situación que, a su vez, limita el tamaño de los espacios ofrecidos.

    Full Text Available Gated communities are an idealized housing model that has spread throughout the contemporary capitalist city. They have been analyzed by social scientist and through artistic representations. Apparently these are two different ways of studying reality, two approaches and two languages. However, they both criticize the residential model and show the contradictions that arise under an image of status, comfort, safety and community harmony. This article analyzes the phenomenon of gated communities according to film narrative. Semionarrative structure and landscape correlative are identified with the idea that they support the critical argument of this urban structure. As a case study, two Latin-American films are analyzed:  Marcelo Piñeyro’s The Widows of Thursdays and Rodrigo Pla’s The Zone.

    Las urbanizaciones cerradas son un modelo habitacional idealizado que se disemina por las ciudades capitalistas contemporáneas. Como tal, han sido objeto de análisis de múltiples investigaciones sociales y de algunas narraciones artísticas. Aparentemente se trata de dos formas diversas de abordar la realidad, dos enfoques y dos lenguajes. Sin embargo, ambos critican el modelo residencial y muestran las contradicciones que se presentan bajo la imagen del estatus, el confort, la seguridad y la armonía con la comunidad. En el presente artículo, se analiza el fenómeno de las urbanizaciones cerradas, desde la narración cinematográfica. Para ello se identifica la estructura semionarrativa y el paisaje correlativo, bajo la idea que fortalecen la argumentación crítica de dicha estructura urbana. Como caso concreto se abordan dos películas latinoamericanas: Las Viudas de los Jueves de Marcelo Piñeyro y La Zona de Rodrigo Plá.

    Tratamiento del síncope neuralmente mediado con marcapasos: utilidad del sensor de asa cerrada

    Full Text Available El síncope vasovagal es una entidad frecuente, de difícil manejo, con alta tasa de recurrencia aun con manejo médico. Se ha estudiado la estimulación cardiaca en pacientes con respuesta cardioinhibitoria en la mesa basculante con resultados contradictorios. Los estudios iniciales mostraron buenos resultados, que no lograron reproducirse cuando se introdujo el diseño doble ciego. La mayoría de estos estudios se realizaron con marcapasos con sensores convencionales. Las guías actuales de dispositivos indican la terapia de estimulación cardiaca en síncope vasovagal con respuesta cardioinhibitoria como una alternativa ante la no respuesta al tratamiento convencional. Existe evidencia reciente que indica que los marcapasos con sensores de asa cerrada (CLS, del inglés closed-loop sensor muestran mejores resultados que los sensores convencionales; estos estudios, aunque con población pequeña, reportan reducciones de la frecuencia de síncopes y presíncopes. Este tipo de dispositivos actúan en etapas más tempranas de la cascada de eventos fisiopatológicos del síncope vasovagal, detectando cambios en la impedancia ventricular antes de la caída de la frecuencia cardiaca, lo cual permite intervenir en forma precoz con estimulación para evitar el síncope.

    Integrated use of geothermal resources is one of the most important goals for the future. Presently geothermal heat pumps offer two benefits: using heat from residual brines and converting these brines into very pure water. Designs and descriptions are presented of an experimental system to purify geothermal brines integrated to an adsorption heat-pump. The system was constructed and tested in the IIE (Institute for Electrical Research) facilities. During the experimental stage, pure water was obtained. Maximum capacity for pure water was 4.3 kg per hour, presenting an Actual Coefficient of Performance (COP)A of 1.4. The results are encouraging to project units at an industrial level for operating with geothermal and/or solar heat. [Spanish] El aprovechamiento integral de los recursos geotermicos en todas sus formas es una de las metas importantes a lograr en los proximos anos. Hoy en dia, el uso de las bombas de calor en la geotermia ofrece un doble beneficio: aprovechan el calor de los fluidos de desecho y tienen la capacidad de transformar la salmuera geotermica en agua de alta pureza. Se presenta el diseno y descripcion de un sistema experimental para purificacion de salmuera geotermica integrado a una bomba de calor por absorcion, el cual fue construido y probado en el Instituto de Investigaciones Electricas. En toda la etapa de experimentacion se obtuvo agua pura. La capacidad maxima alcanzada de produccion de agua pura de este sistema fue de 4.3 kg por hora, mostrando un rendimiento en terminos del Coeficiente Real de Rendimiento (COP)A de 1.4. Estos resultados se consideran alentadores para la proyeccion de unidades a escala industrial que puedan ser operadas con calor geotermico y/o solar.

    Full Text Available La determinación del estado técnico de los sistemas estructurales representa un factor importante en la correcta explotación de los mismos. Existen diversos métodos, en su mayoría visuales, pero que requieren el acceso directo a zonas del sistema y pueden ser poco prácticos cuando los volúmenes de la estructura son grandes [9]. El análisis modal puede ser también empleado, pero también tiene algunas limitaciones. Se ha propuesto a la transformada wavelet como una herramienta de grandes posibilidades en la detección de grietas en estado incipiente. El problema debe ser estudiado tanto práctica como teóricamente, y en el segundo aspecto la correcta representación de la grieta es de importancia fundamental. En este trabajo se representa una grieta cerrada transversal en una viga de Euler-Bernoulli, según la propuesta de Bovsunovsky [1], con modelos continuos y por elementos finitos. Se aplica la transformada wavelet al desplazamiento en los modos de vibración.The determination of the state o a structure represents an important factor in the use of structural systems. This is known as structural health monitoring (SHM. Several methods, the most of them visuals, are employed. These require a direct access to the possible damaged zone and can be very time consuming and costly, a reason by which the researchers in this field are focused in others method, like modal analysis. The wavelet transform is also a very powerful tool in crack detection in early stages. This problem should be studied in a practical and theoretical way. In this paper a transverse closed crack is represented in an Euler-Bernoulli beam, as Bovsunovsky. Continuous and finite element models are used, and the wavelet transform is applied.

    Argentina and, thus, understand the recurrent massacres of native and non-native populations produced by the Argentinean national State in its neo-colonial formation process. Specifically, it will examine two cases which occurred in the past century, long after General Roca's "final solution" in south Argentina and the extermination campaigns carried out by the Argentinean army in the north, and prior to the genocide of the last military dictatorship. These cases are the massacre of Napalpí, which took place in 1924 in Chaco province, and the "Rincón Bomba" massacre of 1947 in Formosa province. Both massacres of indigenous peoples have recently come under review as part of a necessary exercise for truth and memory.

    Full Text Available A implantação de microcentrais hidrelétricas é uma das alternativas para suprir com energia comunidades pequenas e isoladas, situadas normalmente na área rural. O aproveitamento de potenciais hidráulicos de pequeno porte é uma alternativa cada vez mais viável devido não só à falta de recursos financeiros para os grandes empreendimentos, mas também pelo imenso potencial de geração em centrais de pequeno porte, que pouco tem sido aproveitado. O objetivo deste trabalho foi de apresentar uma metodologia simples de engenharia para estimar o custo das Bombas Funcionando como Turbinas (BFTs utilizadas em microcentrais hidrelétricas, que possam ser usadas em estudos preliminares de novos aproveitamentos hidrelétricos, sem uma investigação detalhada dos lugares onde se pretende implantar. Os custos foram obtidos consultando-se diretamente os fabricantes de equipamentos e o mercado da praça de Ponta Grossa - PR. Os resultados mostraram que, para as microcentrais hidrelétricas, sempre que os custos constituírem o aspecto dominante, e para potências até 50 kW, a opção por Bombas Funcionando como Turbinas (BFTs deve ser considerada em lugar das turbinas hidráulicas.The implantation of micro hydroelectric power stations is one of the alternatives to supply energy to small and isolated communities, normally located in rural areas. The use of small load hydraulic potential is an alternative more feasible nowadays, not only because it lacks financial resources for big undertakings, but also, due to the small hydro power station hydraulic generation potential, which just a very small part has been taken advantage of. The objective of this study was to show a simple engineering methodology in order to estimate the electro-mechanic (generating set equipment costs used in micro hydroelectric power plants, which can be applied on preliminary studies about new hydroelectric power stations to be built, without detailed investigation about the

    The arrival of the British colony in Kuala Lumpur sparked a radical change in the town in terms of infrastructure and town planning. Due to the British Empire’s reign over Malaya in the advent of 20th century, the colonial architectural style has influenced a lot of important building in the royal town of Selangor. Some of the building is abandoned disrespect, disregard and it’s frightening. Many deemed historic buildings and structures disappears in exchange for modernity, which is a threat to the townscape and history. The local council of Klang aims to preserve clusters of colonial sights, place of worships, schools, and remnants of a fort that has shaped the town enabling people to be more appreciative towards it. Located in the heart of Klang town, the fire station sits next to another heritage trail icon, Raja Abdullah Warehouse. Without proper documentation and curation, the building significant will remain unknown and eventually disappear. The core of this paper will showcase the building design quality and its importance, as the first attempt to document the Balai Bomba Klang Selatan to assist in conserving its tangible and intangible qualities. The study aims to collate and document the tangible qualities of the fire station to complement the measured drawing exercise.

    Full Text Available El levantamiento planimétrico por poligonal cerrada es un método que ha servido de gran ayuda para poder dar veracidad de un trabajo topográfico bien hecho, visto que por medio de este se logra corregir angular y linealmente una poligonal; sin embargo y como es de conocimiento, la primera penalidad a aplicar es la corrección angular por lo que hemos tratado de profundizar acerca del origen de los errores cometidos en la medición de estos ángulos, en vista que los métodos existentes demuestran como cuantificarlos e incluso como simplificarlos haciéndose valides a parámetros admisibles dotados por la teoría, pero no el origen o punto donde se lo produjo. En el ámbito de la docencia brotan muchas inquietudes tanto del estudiante como del docente durante el desarrollo de la materia, de donde una de ellas ha sido el cómo poder identificar donde se produjo un error para evitar la iteración de todo un trabajo, motivo por el cual se plantea este inédito método que busca encontrar los puntos en los que se producen los errores angulares para poder aplicar correcciones puntuales lo cual se estima que reducirá tiempos y por ende recursos económicos.

    Full Text Available The Maule earthquake (Mw 8.8 that affected south-central Chile on February 27, 2010 was preceded by the 1835 event documented by FitzRoy and Darwin. The relation between both events has been controversial. Fault slip in 2010 estimated by Lorito et al. (2011 is less than expected from 175 years of strain accumulation, leading them to conclude only limited overlap between the 2010 and 1835 events, and that a Mw 7.5-8 event could still strike the Concepción region. However, Lorito et al. 's model was based on displacements obtained from only 6 GPS stations and underpredicts observations from recent studies. Here we show that an alternative model based on 169 GPS displacements reproduces the data better, suggesting Lorito et al. 's main conclusion is not correct. Based on a slip deficit map, we suggest the seismic gap opened in 1835 was most likely closed in 2010.El terremoto del Maule (Mw 8.8 que afectó el centro-sur de Chile el 27 de febrero del 2010 fue precedido por el evento de 1835 documentado por FitzRoy y Darwin. La relación entre ambos eventos ha sido controversial. Los desplazamientos para el 2010 estimados por Lorito et al. (2011 son menores a los esperados en 175 años de acumulación de acortamiento, observación que los llevó a concluir que los eventos del 2010 y 1835 tenían una similitud restringida y que, por ende, un evento de Mw 7.5 a 8 podría afectar la zona de Concepción en el futuro cercano. El modelo de Lorito et al. (2011 usó desplazamientos obtenidos de solo 6 estaciones de GPS y subestima observaciones de estudios recientes. Aquí mostramos que un modelo alternativo basado en 169 estaciones de GPS reproduce los datos mejor, y sugiere que la principal conclusión de Lorito et al. (2011 no es correcta. Basados en un mapa de déficit de deslizamiento sugerimos que la laguna sísmica abierta en 1835 fue muy probablemente cerrada el 2010.

    Full Text Available Es difícil generar con bombas convencionales las condiciones de flujo del sistema cardiovascular, con las cuales se emulen condiciones hemodinámicas para evaluar diferentes dispositivos interpuestos a la corriente sanguínea. Para resolver este inconveniente, se desarrolló un sistema automatizado de bombeo de flujo pulsátil, conformado por un controlador difuso que captura datos de los instrumentos de monitoreo de variables hidrodinámicas a través de una interfaz de adquisición, y aplica señales de control a una bomba de flujo pulsátil. Este sistema permite hacer pruebas hidromecánicas que brindan elementos para interpretar la influencia de las variables que intervienen en el flujo pulsante y simular condiciones hemodinámicas en un ambiente de circulación extracorpórea. Mediante técnicas de diseño asistido por computador, se construyó una bomba de diafragma accionada neumáticamente. El controlador se desarrolló mediante la técnica de Fuzzi Control®, el cual regula el pulso y el flujo de acuerdo con parámetros y datos capturados con la interfaz de adquisición. Las pruebas del prototipo se realizaron en un laboratorio de fluidos variando frecuencia, resistencia hidráulica, viscosidad y presión de pulso, imitando las condiciones hemodinámicas de un adulto y usando como fluido de trabajo una solución acuosa con 5 cPo a 370C, para simular la viscosidad sanguínea a temperatura corporal. La reproducción de una bomba que sirve para analizar el efecto de las variables en el flujo pulsante, puede usarse en el estudio de diferentes dispositivos intravasculares y ayudar a refinar aspectos técnicos y funcionales en el estudio preliminar de máquinas de circulación extracorpórea.With conventional pumps, it is difficult to generate the cardiovascular system conditions that may emulate hemodynamic conditions for evaluating different devices interposed to the blood flow.

    Full Text Available OBJETIVO: Rever a experiência com a utilização da bomba de infusão de insulina em crianças e adolescentes, a fim de orientar o pediatra quanto às suas indicações e complicações. FONTE DOS DADOS : Foi realizada revisão sistemática de artigos publicados em literatura que abordassem a utilização da bomba de infusão de insulina, suas indicações, complicações e resposta ao tratamento. Dessa forma, todos os artigos publicados entre 1995 e 2005 foram resgatados através do levantamento em banco de dados MEDLINE e LILACS. As palavras-chave utilizadas foram: insulin pumps, type 1 diabetes mellitus e diabetes mellitus. Foram separados os artigos que, além disso, versassem sobre o assunto na faixa etária descrita SÍNTESE DOS DADOS: O uso da bomba de infusão de insulina em pacientes com diabetes melito tipo 1 não é uma necessidade para todos os pacientes, visto que, com tratamentos intensivos, os resultados conseguidos são muito parecidos, em termos de hemoglobina glicada e de controle de complicações a médio e longo prazo. No entanto, a bomba permite um maior conforto ao paciente, no sentido de que ele não precisa ficar tão restrito a horários rígidos de refeição e pode levar uma vida com melhor qualidade. Um primeiro requisito para quem pretenda usar a bomba é adaptar-se a aparelhos conectados ao corpo e a ter uma rotina de monitorização glicêmica rigorosa, pois, sem isso, as vantagens da bomba serão anuladas. As complicações, com os avanços tecnológicos de que dispomos atualmente, são muito infreqüentes. O custo, no entanto, é maior que nos tratamentos convencionais. CONCLUSÃO: Com a evolução das bombas de infusão e dos monitores de glicemia, incluindo sistemas de monitorização contínua, abre-se caminho para as "bombas inteligentes", e estaremos com um verdadeiro "pâncreas artificial", que pode mesmo ser implantado no paciente, permitindo uma vida com todas as regalias de uma pessoa não diab

El sistema debe cumplir con requerimientos de alta presión (4.8 MPa y bajos caudales (3.78 L/min, para operar la membrana de osmosis inversa en su rango de mínimo consumo energético. Para cumplir este objetivo se desarrolla un sistema de desplazamiento positivo de acción simple y doble efecto, impulsado con un motoreductor cicloidal. La bomba desarrollada es evaluada experimentalmente bajo condiciones de laboratorio. El análisis de los resultados evidencia altas eficiencias de conversión de energía a lo largo del ciclo de bombeo. Posteriormente, el sistema de bombeo es evaluado en conjunto con una membrana de osmosis inversa, obteniéndose resultados satisfactorios en cuanto a tasas de flujo y concentraciones de permeado. El diseño cumple con los requisitos para sustituir sistemas de bombeo usados en la actualidad, tecnológicamente más complejos y al mismo tiempo más costosos./ The present paper describes the work carried out in the development of a pump system for water desalination in a small reverse osmosis plant. The system must satisfy high pressure (4.8 MPa and low flow rates (3.78 L/min to operate the reverse osmosis membrane in its minimum energy consumption range. In order to achieve this objective, a positive displacement pump system (single action double effect driven by a cyclo speed reduction was developed. The system was tested under laboratory conditions. The analysis of the results shows high energy conversion efficiencies throughout the pumping cycle. The equipment was validated based on the acceptable flow and permeates concentration results. This design is able of replacing actual pump systems that are technologically complex and at the same time more expensive.

    Full Text Available ResumenEn el estudio de la literatura científica sobre las comunidades cerradas publicada hasta la fecha se ha detectado un desequilibrio en cuanto a los enfoques planteados. Un enfoque que hemos etiquetado como sociológico, centrado en las características socioeconómicas, históricas y de gestión interna de la urbanización, es claramente mayoritario frente a un enfoque físico-espacial que se centra en las cualidades y características del soporte material que posibilita el fenómeno de urbanización cerrada. El presente artículo pretende comenzar a equilibrar la balanza aportando conocimiento empírico sobre la morfología y organización espacial de las comunidades cerrada. Centrado en el ámbito de la Comunidad de Madrid, el estudio plantea la hipótesis general de que la homogeneidad de las urbanizaciones en lo que respecta a sus características físico-espaciales y que ha sido tácitamente aceptada por los estudios de enfoque sociológico no es tal, y que es posible distinguir matices y diferencias entre los distintos ámbitos haciendo posible una categorización en función de sus cualidades físicas. Se estudiarán 3 parámetros básicos, a saber, el nivel de cierre de la urbanización, el reparto de los usos del suelo y el trazado del viario. Palabras clave Gated communities, comunidades cerradas, Madrid, características físico-espaciales, urbanizaciones privadas.AbstractIn the study of scientific literature on gated communities published today it has been detected an imbalance in the approaches proposed. One approach that we have labeled as sociological, focusing on socio-economic, historical and internal management of urbanization, is the clear majority against a physical-spatial approach that focuses on the qualities and characteristics of the material that makes possible the phenomenon of gated communities.

    A new computational program has been developed in order to design single stage compression heat pumps. This software, named CICLO 1.0 allows the design of water-water, water-air, air-water and air-air heat pumps, for industrial and residential applications. CICLO 1.0 simulates three types of compressors: reciprocating, screw and scroll. Also has a data base created with REFPROP software which includes eleven refrigerants. The condenser and evaporator simulation includes global conductance (UA) determination, and when one or both are shell and tube's type, this software shows the even number of tube passes by shell. The software determines the best compressor and refrigerant setup taking the COP as a parameter; in order to obtain this, is necessary to know the inlet/outlet conditions of the fluid to be heated, the inlet conditions of the fluid that gives heat, and the electric motor efficiency that drives the compressor. The afforded results by CICLO 1.0 are: operation conditions from compression cycle, that means, pressures and temperatures at the inlet/outlet from every heat pump component are determined: as well as refrigerant mass flux, COP, power required by compressor, volumetric and isentropic efficiencies, heat exchangers global conductance and more data. CICLO 1.0 has been executed with heat pump data that nowadays are operating, and the results from the simulation have been very similar each other with data reported from operational facilities.

    Full Text Available Se experimentó con licor amoniacal con el fin de obtener los valores numéricos de la presión de vapor y establecer una relación entre la caída de presión y la formación de burbujas asociadas al fenómeno de la cavitación en bombas centrífugas que trasiegan este fluido, en el cual están presentes sólidos disueltos y en suspensión. La experimentación se llevó a cabo en dos etapas en las que se obtuvo la presión de saturación del licor amoniacal y la caída de presión cuando se induce la cavitación en una bomba centrífuga. Se concluye que la presión de formación de burbujas durante el trasiego del licor amoniacal a una concentración de 27 % es de 45,6.103 Pa a 22,15 ºC de temperatura de saturación. Estos valores constituyen los límites inferiores de presión para que se produzca la cavitación para una abertura de la válvula del 75 % en las bombas centrífugas que trasiegan licor amoniacal.

Este trabalho objetiva evidenciar o possível efeito hemolítico induzido pelo trauma mecânico provocado pela passagem das hemácias em diferentes modelos de bombas de infusão de soluções, em concentrados de hemácias com até dez dias de armazenamento, preparados com Sag-Manitol. Foram utilizados três modelos de bombas (Nutrimat, Infusomat Compact e Volumed, com quatro aparelhos de cada modelo, testados em três velocidades de infusão (120 mL/h, 240 mL/h e 360 mL/h. Os parâmetros utilizados para evidenciar o grau de hemólise foram o percentual de hemólise e os níveis de hemoglobina e potássio livres no plasma. As amostras foram coletadas antes da passagem do concentrado de hemácias pelas bombas, na metade do tempo de infusão e no final da infusão, nas diferentes velocidades. Não ocorreu variação significativa entre os valores dos parâmetros analisados nas amostras controle e naquelas coletadas nas diferentes velocidades, marcas de bombas, mecanismos de infusão entre as bombas da mesma marca e entre os diferentes tempos de infusão. A principal variação encontrada foi relacionada com o potássio livre, devido à variação inerente aos próprios concentrados, o que foi evidenciado ao se compararem os valores obtidos nas amostras controle e nas amostras colhidas nos tempos médio e final em cada bomba. De acordo com os resultados obtidos, não houve alteração estatisticamente significativa do percentual de hemólise após a passagem pelas bombas de infusão nos modelos analisados.The lyses of red blood cells, both for immune or non-immune reasons, can cause an elevation in plasmatic hemoglobin, inducing harmful effects mainly in the kidneys and cardiovascular system.

    Full Text Available Nos casos de choque cardiogênico após cirurgia cardíaca com auxílio da circulação extracorpórea retratarlos às drogas e ao balão intra-aórtico, as bombas centrífugas têm sido a primeira opção em vários Serviços. Esse fato deve-se à facilidade de manuseio, de instalação, custo razoável, grande disponibilidade, e alto grau de eficiência. O objetivo deste trabalho é o relato da experiência do Instituto do Coração com 8 pacientes submetidos a essa terapêutica, no período de maio de 1990 a dezembro de 1991. Nesses 8 doentes foi utilizado previamente balão intra-aórtico e feito uso maciço de drogas vasoativas. A idade variou de 54 a 66 anos. Três foram submetidos a revascularização do miocárdio, 2 a correção de aneurisma de ventrículo esquerdo, 2 a troca de valva mitral e 1 a transplante cardíaco. Em 7 a assistência foi de ventrículo esquerdo e em 1 de direito. A duração da assistência variou de 18 a 126 horas. Ocorreram três óbitos em assistência, sendo que dois eram pacientes em "ponte" para transplante que não obtiveram doador, e um morreu por complicações de sangramento e insuficiência renal aguda. Dos 5 (62,5% pacientes retirados da assistência, 2 faleceram tardiamente sendo 1 com pulmão de choque e 1 com complicação neurológica e insuficiência renal. Quando comparamos a evolução clínica com o pico de CKMB, verificamos que os 3 pacientes com pico maior que 80 faleceram, 2 em assistência e 1 tardiamente. Dos 5 doentes com pico de CKMB menor que 80, 4 foram retirados de assistência, com 3 sobreviventes tardios, e o único que morreu em assistência foi por problemas de sangramento. Os 3 (35% pacientes sobreviventes estão no 5º, 9º e 19º meses de seguimento, 2 em classe funcional II e 1 em classe I. A utilização precoce, antes de complicações irreversíveis, da assistência circulatória, deverá permitir resultados progressivamente melhores, nesse grupo de pacientes de alto risco

    Full Text Available MATERIAL E MÉTODOS: Foi testado em 30 cães um circuito capaz de promover circulação extracorpórea (CEC com oxigenação autógena (OA do sangue, usando apenas uma bomba centrífuga. Esta montagem dispensou bombeamento para o lado direito: o gradiente de pressão bastante para vencer a resistência arterial pulmonar foi vencido aumentando-se a pressão nas artérias pulmonares pela expansão da volemia e diminuindo-se a pressão do átrio esquerdo pela drenagem dessa câmara mediante um sifão. O coração foi mantido em ritmo de fibrilação ventricular durante o período de perfusão e ao seu término, o ritmo próprio foi recuperado mediante cardioversão elétrica. RESULTADOS: Este circuito permitiu a manutenção de parâmetros hemodinâmicos e gases sangüíneos adequados durante a perfusão. O campo operatório e a mobilidade do coração foram similares aos proporcionados pela CEC convencional. CONCLUSÃO: Concluímos que o uso de bomba centrífuga única simplifica a OA, podendo tornar-se uma escolha prática nos procedimentos de revascularização do miocárdio.It was tested in 30 dogs a circuit capable to allow extracorporeal circulation (ECC with autogenous oxygenation (AO of the blood employing an only centrifugal pump.

The heart was electrically fibrillated in the beginning of the bypass and defibrillated in the end. This circuit allowed the maintenance of normal hemodynamic parameters and normal blood gases level during ECC. The operative field and the mobility of the heart were similar to those provided by conventional CEC. We concluded that the use of an only centrifugal pump simplifies ECC with AO, turning it a practical choice for the procedures of myocardial

    The implantation of micro hydroelectric power stations is one of the alternatives to supply energy to small and isolated communities, normally located in rural areas. The use of small load hydraulic potential is an alternative more feasible nowadays, not only because it lacks financial resources for big undertakings, but also, due to the small hydro power station hydraulic generation potential, which just a very small part has been taken advantage of. The objective of this study was to show a simple engineering methodology in order to estimate the electro-mechanic (generating set) equipment costs used in micro hydroelectric power plants, which can be applied on preliminary studies about new hydroelectric power stations to be built, without detailed investigation about the places where they should be implanted. Pumps as turbines (PAT) have been studied. These equipment costs were obtained by consulting directly the manufacturers, and also the Ponta Grossa - PR city, Brazil, market. The results have shown that, concerning the micro hydroelectric power plants, whenever the costs constitute the major aspect and always considering units until 50 kW power, the option to PAT must be considered instead of hydraulic turbines.

    Full Text Available The Montreal Definition and Classification divides Gastroesophageal Reflux Disease (GERD into esophageal symptomatic syndromes (and with mucosal damage and extraesophageal syndromes (with acid established association and proposed association. In typical GERD symptoms, an 8-week treatment with PPIs is satisfactory in most cases (> 90%. Response rates to PPIs in GERD are highly variable, as they also rely on an appropriate clinical diagnosis of the disease; endoscopy differentiates the macroscopic GERD phenotype. The non-erosive variety (50-70% prevalence has a different symptomatic response rate, as gastric acid is not the sole etiology of symptoms. The possible explanations of treatment failure include treatment adherence, PPI metabolism alterations and characteristics, and inadequate diagnosis. Refractory symptoms are related to gastric content neutralization by the chronic use of PPIs. Extraesophageal manifestations are associated with other pathophysiological mechanisms where an autonomic nervous system disturbance gives rise to symptoms. In these clinical entities, the relationship between symptoms and acid needs to be established in order to determine the use of PPIs, or consider other drugs. In other words, so as to "custom-tailor the best-fitting therapy" we need to answer the questions for whom, for what, how and for how long. Finally, PPI safety and tolerability are factors to be considered in elderly patients requiring chronic PPI use, who usually have chronic concomitant illnesses.La Clasificación de Montreal divide la enfermedad por reflujo gastro-esofágico (ERGE en síndromes esofágicos sintomáticos y con daño a la mucosa y en síndromes extraesofágicos con asociación establecida al ácido y asociación propuesta.

Este trabajo tiene como objetivo determinar los flujos de emisiones in situ de CO2 y N2O desde un suelo derivado de cenizas volcánicas bajo diferentes prácticas de manejo agronómico determinando su variación estacional. Las muestras gaseosas fueron obtenidas desde el espacio aéreo de cámaras cerradas no-fijas en una rotación anual de cultivos bajo sistema de cero labranza en un Andisol del Sur de Chile (36° S. Dos fuentes de N (NH4+ y NO3- y fertilización amoniacal más dos dosis de encalado (0.5 y 1 Mg ha-1 fueron considerados como tratamientos. Los flujos de CO2 y N2O fueron determinados periódicamente en un período de 1 año y variables de suelo tales como temperatura, contenido de agua, y N mineral fueron registrados. Los resultados muestran que los flujos de CO2 responden a patrones de estacionalidad. No fue evidenciado un efecto cuando fue considerada la práctica de manejo del cultivo, con un máximo de 53.2 ± 8.5 kg CO2-C ha-1 d-1 en la estación húmeda de otoño, y un mínimo de 9.7 ± 2.1 kg CO2-C ha-1 d-1 para verano, estación seca de otoño e invierno. El flujo de N2O fue altamente variable en el año y no muestra influencia de tratamientos o estacionalidad, con un promedio de 2.6 ± 0.6 g N2O-N ha-1 d-1. Variaciones de N mineral del suelo no están relacionadas a los flujos de GHG como una variable sola. Los resultados indican que un Andisol bajo sistema de cero labranza en el Sur de Chile tiene un bajo potencial de emisiones de N2O, y las mayores emisiones de CO2 son producidas principalmente en estaciones húmedas (otoño húmedo y/o primavera.

    The central problem of the dosimetry of the ionizing radiations is the determination of the dissipated energy by unit of mass of irradiated material. This energy usually is inferred of ionization measures in a small cavity of air housed inside the material medium. The Bragg-Gray cavity theory was the first one in estimating the dissipated energy through the ionizations that the primary electrons cause in the cavity. The primary electrons are generated by photoelectric effect, pair production and by Compton dispersion of the photon beams that initially impact on the material. However, in a more realist approach the existence of secondary electrons due to the electron-electron interaction it will be considered. The Spencer-Attix cavity theory considers to the secondary electrons as responsible part for the energy deposited in the means, for that a total spectral fluence of electrons (primary and secondary) it appears in this theory. Few electrons spectra have been published, mainly, those that include the contribution of secondary electrons ({delta} rays). Leaving of the ideas of Spencer-Attix, in this work an approach method to determine the rate of electron spectral fluences (total regarding primary) for a wide variety of material Z, and energy sources T{sub 0} is presented. The method for materials used by Spencer-Attix is applied, it is proven its reliability and it is applied to the water like absorber medium by its importance in the clinical dosimetry. (Author)

    Full Text Available Nouns meaning ‘place, region’ and ‘part’ are compounded in Kannada with a `bleached’ noun (a putative postposition to form AxPart and Part readings. As in other languages, the AxPart or ‘region’ reading does not pluralize, does not permit adjectival modification, and allows for MeasureP modification (unlike the part reading. AxParts may also be formed out of nouns by the fusion of a dative marker or a genitive marker with the N; these case markers introduce the Place element. The dative case may be optionally overt (e.g. pakka-kke ‘side-dative,’ ‘to a side’, or covert (in AxParts like munde ‘front’. The genitive marker gives a sense of immediate adjacency that we designate the NextPart reading. Interestingly, the dative and genitive cases in Kannada also allow nouns to assume the function of predicative and attributive adjectives.

SBPkb transforms this information so that it is computable, using our semantic framework for synthetic biology parts. This framework, known as SBOL-semantic, was built as part of the Synthetic Biology Open Language (SBOL), a project of the Synthetic Biology Data Exchange Group. SBOL-semantic represents commonly used synthetic biology entities, and its purpose is to improve the distribution and exchange of descriptions of biological parts. In this paper, we describe the data, our methods for transformation to SBPkb, and finally, we demonstrate the value of our knowledgebase with a set of sample queries. We use RDF technology and SPARQL queries to retrieve candidate "promoter" parts that are known to be both negatively and positively regulated. This method provides new web based data access to perform searches for parts that are not currently possible.

    The Controlled Parts Management (CPM) system is based on industry standard practices for managing inventory. CPM is designed to record the movement of any type of inventory in a defined region referred to as an Account or SubAccount. The system is used to track the receiving, processing, storing and transfer of inventory parts. CPM provides information on parts, quantity and the exact location of the inventory. CPM is a barcode-based-part tracking system currently used to track controlled parts that are used in the R and D and testing of weapons; this tracking helps maintain the part pedigree that is required for certification of a weapon or weapon test. CPM includes bar code data collection software programmed into portable bar code readers for automating physical inventory services and remote transaction capture. CPM interfaces to other Engineering systems and supports a 'material content' of a weapons test through the test Bill of Materials and assignment of a unique inventory part in CPM. Additional functionality includes the ability to group or join parts, logically or physically and temporary or permanent, to represent discrete parts, containers, subassemblies and assemblies, and groupings.

    1990-01-01

    The object of the present invention is to eliminate unnecessary information caused by sounds which requires no analysis since the sound source is apparent. The loose parts monitoring device comprises detectors attached to an equipment constituting a flow channel, a signal controller for outputting a predetermined signal based on the signals from the detectors and a judging means for outputting an alarm upon occurrence of loose parts based on each of signal controllers. Information for a specific combination of a plurality of detectors and specific time difference are stored in the judging means. Then erroneous signals are removed by comparison between the stored information and the number of signals from a plurality of detectors within a predetermined time. Thus, in the case of predetermined combination signals, i.e., noises due to plant operation (control rod operation, etc.), for which the sound source is previously recognized, can be eliminated from loose parts signals.

    Ferrare, J.

    1989-01-01

    Florida Power ampersand Lights's (FP ampersand L's) Turkey Point units were built prior to the establishment of American Society of Mechanical Engineers' Sec. III requirements. Since that time, FP ampersand L has voluntarily committed to procuring some spare and replacement parts in compliance with the ordering requirements of ASME Sec. III. New subsystems were designed according to ASME Sec. III requirements. In 1978, 10CFR21 of the Code of Federal Regulations was federally mandated. Environmental qualification concerns and the Three Mile Island incident further complicated the stocking and ordering of spare and replacement parts. Turkey Point assembled a team of quality assurance, quality control, and engineering people and obtained permission to directly access the store department computer so that catalog descriptions could be quickly made available for use by the plant. The total equipment parts configuration (TEPC) system was designed and developed under the direction of the procurement document review team at the Turkey Point nuclear plant. The system is a network of related computer data bases that identifies the equipment at the plant. The equipment (or components that make up a piece of equipment) is identified by a tag/component code system. Each component is further broken down by the manufacturer's parts list or bill of material. A description of the data available to the user, the ways these data can be accessed and displayed, and a description of the data bases and their relation to each other are summarized in this paper

    1992-01-01

    For the last half decade, regulatory expectations of the procurement process for nuclear commercial-grade safety-related materials have increase. The changes have been driven by concern for fraudulent or misrepresented parts and the loss of original equipment manufacturers. The industry responded to these concerns by developing improved procurement programs that changed how parts were specified and received and provided for verification of attributes that were critical to the successful performance of safety functions(s). Like its counterparts, Duquesne Light Company (DLCo), Beaver Valley power station began applying these enhanced requirements to procurements initiated after January 1, 1990, in response to the Nuclear Management and Resources Council initiative on dedication. Procurements prior to this data were not subject to the new requirements

    Rickets is characterized by impaired mineralization and ossification of the growth plates of growing children caused by a variety of disorders, the most frequent of which is nutritional deficiency of vitamin D. Despite ample knowledge of its etiology and the availability of cost-effective methods of preventing it, vitamin D deficiency rickets remains a significant problem in developing and developed countries. This two-part review covers the history, etiology, pathophysiology and clinical and radiographical findings of vitamin D deficiency rickets. Other less frequent causes of rickets and some of the disorders entering into the differential diagnoses of rickets are also considered. Controversial issues surrounding vitamin D deficiency include determination of what constitutes vitamin D sufficiency and the potential relationship between low levels of vitamin D metabolites in many individuals and unexplained fractures in infants.

    In addition to dealing with the normal challenges of being a teenager, many times LGBTQ youth have to deal with harassment, intimidation, and bullying on a daily basis as they disproportionately experience verbal and physical harassment while in school as a result of their sexual orientation and/or gender identity. This violence adversely affects these students' health and well-being as reflected in the depression and suicide rate among LGBTQ youth. As Part 2 of a series in articles on caring for LGBTQ youth in a school setting, this article reviews specific health risks in this group of students. School nurses can help reduce disparities in health for LGBTQ youth by understanding risk for psychological consequences of bullying and advocating for a just and responsive social school culture. Implications for school nurses include educating school staff and families as well as providing prompt and appropriate referrals for necessary psychological care.

In the evaluation of Hungarian side only the results obtained for the period from 1992 to 1995 were analysed. Moreover, on the Slovak side an evaluation of the health conditions of trees based on aerial was carried out. The Hungarian party did not carried out such a survey, therefore the evaluation is based only on field (on-the-spot) observations

  5. [Neurology! Adieau? (Part 2)].

    Szirmai, Imre

    2010-05-30

    The education of neurologists is debilitated worldwide. University professors are engaged in teaching, research and patient-care. This triple challenge is very demanding, and results in permanent insecurity of University employees. To compensate for the insufficient clinical training, some institutes in the USA employ academic staff members exclusively for teaching. The formation of new subspecialties hinders the education and training of general neurologists. At present, four generations of medical doctors are working together in hospitals. The two older generations educate the younger neurologists who have been brought up in the world of limitless network of sterile information. Therefore their manual skills at the bedside and their knowledge of emergency treatment are deficient. Demographics of medical doctors changed drastically. Twice as many women are working in neurology and psychiatry than men. Integrity of neurology is threatened by: (1) Separation of the cerebrovascular diseases from general neurology. Development of "stroke units" was facilitated by the better reimbursement for treatment and by the interest of the pharmaceutical companies. Healthcare politics promoted the split of neurology into two parts. The independent status of "stroke departments" will reduce the rest of clinical neurology to outpatient service. (2) The main argumentation to segregate the rare neurological diseases was that their research will provide benefit for the diseases with high prevalence. This argumentation serves territorial ambitions. The separation of rare diseases interferes with the teaching of differential diagnostics in neurological training. The traditional pragmatic neurology can not be retrieved. The faculty of neurology could retain its integrity by the improvement of diagnostic methods and the ever more effective drugs. Nevertheless, even the progression of neurological sciences induces dissociation of clinical neurology. Neurology shall suffer fragmentation if

  6. Part II. Population

    International Nuclear Information System (INIS)

    2004-01-01

    This monograph deals with assessment of radiological health effects of the Chernobyl accident for emergency workers (part 1) and the population of the contaminated areas in Russia (part 2). The Chernobyl emergency workers and people living in the contaminated areas of Russia received much lower doses than the population of Hiroshima and Nagasaki and it was unclear whether risks of radiation-induced cancers derived with the Japanese data could be extrapolated to the low dose range However, it was predicted as early as in 1990 that the thyroid cancer incidence might be increasing due to incorporated 131 irradiation. What conclusions can be drawn from regarding cancer incidence among emergency workers and residents of the contaminated areas in Russia and the role of the radiation factor on the basis of the registry data? Leukemia incidence. Leukemia incidence is known to be one of principal indications of radiation effects. The radiation risk for leukemias is 3-4 times higher that for solid cancers and its latent period is estimated to be 2-3 years after exposure. Results of the radiation epidemiological studies discussed in this book show that in the worst contaminated Bryansk region the leukemia incidence rate is not higher than in the country in general. Even though some evidence exists for the dose response relationship, the radiation risks appear to be not statistically significant. Since risks of leukemia are known to be higher for those who were children at exposure, long-term epidemiological studies need to be continued. The study of leukemias among emergency workers strongly suggest the existence of dose response relationship. In those who received external doses more than 0.15 Gy the leukemia incidence rate is two time higher and these emergency workers should be referred to as a group of increased radiation risk. Solid cancers. The obtained results provide no evidence to a radiation-induced increase in solid cancers among residents of the contaminated areas

El cine argentino, entre otras manifestaciones, se encargó de impugnar el estilo de vida que estas urbanizaciones proponen. En cambio, una serie de publicaciones gráficas de distinto tipo asumieron la tarea de dotarlas de legitimidad y promover una serie de valores que les están asociados. Los suplementos “Countries” de Clarín y La Nación son la evidencia más notoria. Aquí proponemos analizar una muestra de las publicidades que aparecen allí a partir de algunos interrogantes: ¿qué temas instalan? ¿Cuáles son silenciados? ¿Cómo son representados los sujetos y el espacio? La hipótesis central es que allí se ponen en juego elementos críticos a fin de legitimar la inserción social del estilo de vida country.

  4. VULNERABILITY OF PART TIME EMPLOYEES

    Directory of Open Access Journals (Sweden)

    Raluca Dimitriu

    2015-11-01

    Full Text Available The employee who concluded a part-time contract is the employee whose normal working hours, calculated weekly or as monthly average, is lower than the number of normal working hours of a comparable full-time employee. Part-time workers generally have the same legal status as full time workers. In fact, the vulnerability of this category of workers is not necessarily legal but rather economic: income - in proportion to the work performed, may be insufficient to cover the needs of living. However, such vulnerability may also have a certain cultural component: in some societies, professional identity is determined by the length of working hours. Also, part time work may hide many types of indirect discrimination.As a result, the part-time contract requires more than a protective legislation: it requires a strategy. This paper proposes a number of milestones of such a strategy, as well as some concrete de lege ferenda proposals.

    Centrifugal pumps are widely used in Spain for driving water or other liquids, but they are not always operated in the most appropriate way. This gives rise to an additional energy cost of approximately 50.000 million pesetas a year. Two examples of inadequate functioning are given-for flows of 10 l/sec at 60 m water leg and 500 l/sec at 200 m water leg- showing the economic savings from small performance improvements. A graph is used to indicate the performance to be expected from a pump, the pump operating areas and their effect on cavitation, axis deflection, etc. A thermodynamic method is presented based on liquid entry and exit pressure and temperature measurements which enables the pump`s performance to be restored following appropriate repairs.

    It is made from an absorbent material that has natural fibers and cellulose in its composition. The polyurethane bio-foam presented excellent levels of absorption of the toxic residues left by gasoline such as carbon monoxide, hydrocarbons, oxygen, nitrogen and sulfur. All the materials used in the composition of Gasolimp are biodegradable. After a four-year research period we found out that from five to eight drops of gasoline are spilt at the moment that car pump is being filled up and they end up either in the cloth the attendant holds in his hand, on his hand, on his clothes, on the car paint or on the soil. The research shows that the toxic effects the gasoline hydrocarbons cause health problems to the attendants such as headaches, lesions on their hands and eyes, dizziness, gastro-intestine problems, heart palpitation, breathing problems and can even affect the central nerve system. The final use of the product has the utmost importance: after thirty days of use Gasolimp must be replaced and when re-used it may be sent to mills and earthenware factories and there it will function as a product that will co-generate power.

    Milk is a prominence product of Brazilian agriculture, with about 2/3 of the rural properties dedicated to the milkmaid cattle breeding, the second bigger flock of the world and a representative participation in the national economy. In spite of its size, the sector still suffers of low productivity, high costs, the instability of prices and technological delay, which resulted in many producers have abandoned its activities in consequence of this new competitive scenario. Nowadays, subjects as, the rational use of energy and intensive application of technology have been hardly discussed, and indicated, as important aspects to obtain high productivity gains. In this work, it is presented an evaluation of the use of energy in a milkmaid which processes cooled raw milk in Morungaba city, Sao Paulo state, Brazil, with a 1.000 liters daily production, making use of the three main processes (cooling, milking system and water heating). Aiming at to promote the rational use of energy, it was realized in this property, an adequacy in the tank milk cooler to utilize the condensation heat, of the refrigeration system, to heat cleanness water (operation according to a heat pump). Through this practical, it was objectified the exclusion of the use of the electric resistance in the heating process for term -accumulation (300 liters/day), promoting consumption reduction and rational use of energy.

    The competitive market where the petroleum and petrochemicals industries are inserted has been taking to significant reductions of its profit margins, leading them to pursue costs reduction and change its way of working, in order to turn them more competitive. The reliability of the plant has a direct impact in the operational costs and it is extremely dependent of the performance of the rotating equipment, predominantly centrifugal pumps. Investments for optimize the reliability of the plants and to reduce the maintenance needs have become imperative for the reduction of the operational and maintenance costs. And why do the pumps fail so much? This is a question that all the pump users make themselves, dealing with an apparently so simple equipment. The pump maintenance costs is about 30 % of rotating equipment total cost.Vibration, mechanical seal failures and efficiency loss are the greatest responsible causes of such high maintenance costs. Many factors should be considered in the analysis of the causes of such low performance. Errors of project, application, installation, maintenance and operation of the pumps are the greatest responsible factors for its low performance. This article makes a detailed analysis of the impact of these factors in the performance of these equipment, discussing the best practices that should be adopted and maintained, in order to assure an optimum reliability.

  1. Hydroforming of flanged tubular part

    International Nuclear Information System (INIS)

    Joo, B. D.; Jang, J. H.; Choi, M. K.; Moon, Y. H.

    2010-01-01

    Tube hydroforming is the technology that utilizes hydraulic pressure to form a tube into desired shapes inside die cavities. Recently, tube hydroforming technology draws attentions of automotive industries due to its advantages such as weight reduction, increased strength, improved quality and reduced tooling cost. Hydroformed automotive parts used as structural components in vehicle body frame or subframe often have to be structurally joined at some point. Therefore it is useful if the hydroformed automotive parts can be given a localized attachment flange. In this study, a tube hydroformed product which has flange has been formed at various processing conditions. To accomplish successful flange hydroforming process, thorough investigation on proper combination of process parameters such as internal hydraulic pressure and tool geometry has been performed. For the process design FE analysis was performed with Dynaform 5.5. With optimized die parting angle and circumferential expansion ratio, hydroforming experiments to form flange were performed and forming characteristics at various process conditions were analyzed. The results show that flanged parts can be successfully produced by tube hydroforming process.

  7. Cleaning of parts for new manufacturing and parts rebuilding

    Science.gov (United States)

    Doherty, Jeff

    1994-06-01

    Parts cleaning is the largest single expense, and the most time consuming activity, in rebuilding and new manufacturing. On average, 25% to 40% of the total labor and overhead burden is spent on cleaning. EPA and OSHA pressures add to the burden by making some methods and chemicals obsolete. Some of the processes and chemicals in current use will be curtailed and or outlawed in the future. How can a shops and industries make long term decisions or capital investments in cleaning and process improvements when the government keeps changing its rules? At the MART Corporation in Saint Louis, Missouri, we manufacture a line of cabinet-style batch cleaning machines known as Power Washers. Twenty years ago MART invented and patented the Power Washer process, a cleaning method that recycles wash solution and blasts contaminates as they are washed off the more heavily contaminated parts. Since the initial invention MART has continued to R&D the washing process and develop ancillary systems that comply with EPA and OSHA regulations. For applications involving new industrial parts or items requiring specification cleaned surfaces. MART provides filtration and solution conditioning systems, part drying operations, and triple rinsing. Units are available in stainless steel or higher alloys. We are not alone in the washer manufacturing business. You have many choices of cleaning solutions (no pun intended) which will perform in your operations and yield good results. As a manufacturer, we are interested in your success with our equipment. We have all heard the horror stories of companies having selected inappropriate cleaning systems and or processes which then brought the company to its knees, production wise. Assembly, appearance, warranty, and performance shortcomings of finished products can often be directly related to the cleaning process and its shortcomings.

    Worldwide interest in technical details concerning major components of world-scale MTBE complexes continues. Part 1 reviewed alternate scenarios for MTBE production and basic technological considerations to assess component processes for producing MTBE. Commercial technologies and cost considerations for world-scale MTBE complexes call for a focus on butane isomerization, isobutane dehydrogenation and isobutylene etherification. The paper describes isomerization; four commercial processes for dehydrogenation (Oleflex, Catofin, STAR, and FBD-4 processes); three methods for etherification (fixed bed with recycle, fixed bed tubular reactor, and catalytic distillation); and capital and production costs for the MTBE complex.

    Part 1 of this guideline addressed the differential diagnosis of the neurofibromatoses (NF): neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2) and schwannomatosis (SCH). NF shares some features such as the genetic origin of the neural tumors and cutaneous manifestations, and affects nearly 80 thousand Brazilians. Increasing scientific knowledge on NF has allowed better clinical management and reduced rate of complications and morbidity, resulting in higher quality of life for NF patients. Most medical doctors are able to perform NF diagnosis, but the wide range of clinical manifestations and the inability to predict the onset or severity of new features, consequences, or complications make NF management a real clinical challenge, requiring the support of different specialists for proper treatment and genetic counseling, especially in NF2 and SCH. The present text suggests guidelines for the clinical management of NF, with emphasis on NF1.

    An outline is given of the social dilemmas associated with agriculture and horticulture in the Netherlands. Ongoing innovation and accelerated sustainable development are essential to resolve these dilemmas. Given the importance of the Dutch agriculture and horticulture sector, there is every reason for the central government to play its part and help remove the obstacles to the continuing sustainable development of the sector. The Council recommends that the central government continues developing the Council's vision for agriculture and horticulture with the parties concerned, allows scope for the development of different agricultural business models, applies knowledge and innovation as drivers of continuing sustainable development, amends laws and regulations as necessary, and facilitates a permanent dialogue between the sector and society. The advisory report also sets out the Council's vision concerning the political and public debate on agriculture and horticulture. This debate is most clearly characterised by major and seemingly insurmountable differences of opinion. The Council hopes that its report will induce a shift in thinking about Dutch agriculture among politicians and society at large, so that the transitions considered necessary by the Council can be implemented more rapidly.

    Full Text Available Systemic sclerosis is an immune-mediated disease characterized by a chronic and progressive course. It often leads to multiorgan failure and patient disability, and contributes to significant reduction in the quality of life. Systemic sclerosis affects the skin, subcutaneous tissue, muscles, osteoarticular system and internal organs. The complexity and diversity of clinical presentations require an individual approach and multidisciplinary collaboration both at the stage of diagnosis and treatment. Critical factors in systemic sclerosis include early diagnosis, assessment of internal organ involvement, identification of patients at potential risk of organ complications, assessment of disease dynamics and activity, and implementation of optimal therapy. Part 1 presents current recommendations for the diagnostics and monitoring of patients with systemic sclerosis. Attention is given to classification criteria, clinical forms of systemic sclerosis, assessment of skin thickness and systemic sclerosis microangiopathy, significance of antinuclear antibodies, diagnosis of interstitial lung disease and pulmonary arterial hypertension, renal crisis and cardiac abnormalities, and evaluation of the gastrointestinal tract and osteoarticular and muscular systems.

  5. Commercial Parts Technology Qualification Processes

    Science.gov (United States)

    Cooper, Mark S.

    2013-01-01

    Many high-reliability systems, including space systems, use selected commercial parts (including Plastic Encapsulated Microelectronics or PEMs) for unique functionality, small size, low weight, high mechanical shock resistance, and other factors. Predominantly this usage is subjected to certain 100% tests (typically called screens) and certain destructive tests usually (but not always) performed on the flight lot (typically called qualification tests). Frequently used approaches include those documented in EEE-INST-002 and JPL DocID62212 (which are sometimes modified by the particular aerospace space systems manufacturer). In this study, approaches from these documents and several space systems manufacturers are compared to approaches from a launch systems manufacturer (SpaceX), an implantable medical electronics manufacturer (Medtronics), and a high-reliability transport system process (automotive systems). In the conclusions section, these processes are outlined for all of these cases and presented in tabular form. Then some simple comparisons are made. In this introduction section, the PEM technology qualification process is described, as documented in EEE-INST-002 (written by the Goddard Space Flight Center, GSFC), as well as the somewhat modified approach employed at the Jet Propulsion Laboratory (JPL). Approaches used at several major NASA contractors are also described

  6. Drilling miniature holes, Part III

    Energy Technology Data Exchange (ETDEWEB)

    Gillespie, L.K.

    1978-07-01

    Miniature components for precision electromechanical mechanisms such as switches, timers, and actuators typically require a number of small holes. Because of the precision required, the workpiece materials, and the geometry of the parts, most of these holes must be produced by conventional drilling techniques. The use of such techniques is tedious and often requires considerable trial and error to prevent drill breakage, minimize hole mislocation and variations in hole diameter. This study of eight commercial drill designs revealed that printed circuit board drills produced better locational and size repeatability than did other drills when centerdrilling was not used. Boring holes 1 mm in dia, or less, as a general rule did not improve hole location in brass or stainless steel. Hole locations of patterns of 0.66-mm holes can be maintained within 25.4-..mu..m diametral positional tolerance if setup misalignments can be eliminated. Size tolerances of +- 3.8 ..mu..m can be maintained under some conditions when drilling flat plates. While these levels of precision are possible with existing off-the-shelf drills, they may not be practical in many cases.

  19. Changing nature of equipment and parts qualification

    International Nuclear Information System (INIS)

    Bucci, R.M.

    1988-01-01

    Ideally, the original supplier of a piece of nuclear safety-related equipment has performed a qualification program and will continue to support that equipment throughout the lifetime of the nuclear power plants in which in equipment is installed. The supplier's nuclear quality assurance program will be maintained and he will continue to offer all necessary replacement parts. These parts will be identical to the original parts, certified to the original purchase order requirements, and the parts will be offered at competitive prices. Due to the changing nature of the nuclear plant equipment market, however, one or more of those ideal features are frequently unavailable when safety-related replacement equipment or parts are required. Thus, the process of equipment and parts qualification has had to adjust in order to ensure obtaining qualified replacements when needed. This paper presents some new directions taken in the qualification of replacement equipment and parts to meet changes in the marketplace

    This paper describes a maintenance problem in a fusion power plant. The problem is to specify which life limited parts should be replaced when there is an opportunity. The objective is to minimize the cost rate of replacement parts and of maintenance actions while satisfying a power plant availability constraint. The maintenance policy is to look ahead and replace all parts that will reach their life limits within a time called a screen. Longer screens yield greater system availabilities because more parts are replaced prior to their life limits

    Esterling, D. M.; Vanrosendale, J.

    1984-01-01

    The problem of deciding whether moving mechanical parts will collide during motion arises frequently in computer-aided design of machinery and in robotics. In machinery design, the problem becomes acute when there are various complex curved mechanical parts that will follow planned trajectories. There is a need to know at an early stage in the design process whether there will be collisions between parts necessitating changes in part shapes, trajectories, or in the overall design. This paper describes a collision detection algorithm that is guaranteed to detect a collision if one will occur, and it also computes the earliest point of contact.

    Cole, Reysen, and Kelley [2013. Part-set cuing facilitation for spatial information. Journal of Experimental Psychology: Learning, Memory, & Cognition, 39, 1615-1620] reported robust part-set cuing facilitation for spatial information using snap circuits (a colour-coded electronics kit designed for children to create rudimentary circuit boards). In contrast, Drinkwater, Dagnall, and Parker [2006. Effects of part-set cuing on experienced and novice chess players' reconstruction of a typical chess midgame position. Perceptual and Motor Skills, 102(3), 645-653] and Watkins, Schwartz, and Lane [1984. Does part-set cuing test for memory organization? Evidence from reconstructions of chess positions. Canadian Journal of Psychology/Revue Canadienne de Psychologie, 38(3), 498-503] showed no influence of part-set cuing for spatial information when using chess boards. One key difference between the two procedures was that the snap circuit stimuli were explicitly connected to one another, whereas chess pieces were not. Two experiments examined the effects of connection type (connected vs. unconnected) and cue type (cued vs. uncued) on memory for spatial information. Using chess boards (Experiment 1) and snap circuits (Experiment 2), part-set cuing facilitation only occurred when the stimuli were explicitly connected; there was no influence of cuing with unconnected stimuli. These results are potentially consistent with the retrieval strategy disruption hypothesis, as well as the two- and three-mechanism accounts of part-set cuing.

  2. Recurring part arrangements in shape collections

    KAUST Repository

    Zheng, Youyi

    2014-05-01

    Extracting semantically related parts across models remains challenging, especially without supervision. The common approach is to co-analyze a model collection, while assuming the existence of descriptive geometric features that can directly identify related parts. In the presence of large shape variations, common geometric features, however, are no longer sufficiently descriptive. In this paper, we explore an indirect top-down approach, where instead of part geometry, part arrangements extracted from each model are compared. The key observation is that while a direct comparison of part geometry can be ambiguous, part arrangements, being higher level structures, remain consistent, and hence can be used to discover latent commonalities among semantically related shapes. We show that our indirect analysis leads to the detection of recurring arrangements of parts, which are otherwise difficult to discover in a direct unsupervised setting. We evaluate our algorithm on ground truth datasets and report advantages over geometric similarity-based bottom-up co-segmentation algorithms. © 2014 The Author(s) Computer Graphics Forum © 2014 The Eurographics Association and John Wiley & Sons Ltd.

    The cost benefits have been demonstrated for an integrated program, which is currently being implemented for two PWR stations with two 1100-MW units each. The component classification efforts reduced the number of safety-related components in several systems. Furthermore, the knowledge of the component specific function has contributed to the reduction of many safety-related parts per component, in addition to ensuring the procurement of parts to the correct safety level. The use of qualified commercial grade parts and components with their lower cost and reasonable procurement lead time compared to their 10 CFR 21 counterparts has a pronounced economic effect on the utility balance sheets

    Full Text Available The article deals with the analysis of a damaged part, which was designed for use in a mechanical clutch of a car. The crack in the part was found during the production inspection. The aim of metallographic and fractography analyses of the fracture surfaces was to discover the reasons for the crack. The reason for creating the crack was the formation of smaller cracks in the production during pressing process of the semiproduct. These cracks even grew after the following thermochemical treatment. The fracture was initiated during the straightening process of quenched part.

  13. Certification of Ada parts for reuse

    Hansen, Gregory A.; Spaulding, S. D.; Edgar, Glenn

    1986-01-01

    One of the claims made by proponents of Ada is that Ada software is highly reusable. The fact that specifications are compiled and accessible would make reusability seem easily achievable. However, specifications give only a limited amount of information about a package; moreover, a specification cannot help determine whether a package worked, or how well it worked. This problem has led to the concept of certifying Ada parts for reuse; that is, determining the worthiness of a part as a reusable component. Issues that are critical to reuse are addressed: the characterization of part performance, design for reuse, and correct utilization of parts. Current areas of study beneficial in the development of a certification process are then addressed.

    1978-01-01

    This is Part 2 of a transcription of Bentham's manuscript essay on "Paederasty" (1785), Part 1 of which appeared in Vol. 3, No. 4. In Part 1 Bentham argued for the decriminalization of sodomy and opposed the theories of Montesquieu and Voltaire as to its social dangers. In Part 2 Bentham speculates on its causes and alleges that the real reason such behavior is so severely punished is an irrational "antipathy" to pleasure generally and to sexual pleasure in particular. He discusses the danger of blackmail and false accusations and the punishment of lesbian acts, bestiality, and masturbation. Some miscellaneous related notes by Bentham are appended: these deal with religious fears based on the destruction of Sodom, the threat to population, the harshness of English naval law, and other topics.

  16. Smart variations: Functional substructures for part compatibility

    KAUST Repository

    Zheng, Youyi

    2013-05-01

    As collections of 3D models continue to grow, reusing model parts allows generation of novel model variations. Naïvely swapping parts across models, however, leads to implausible results, especially when mixing parts across different model families. Hence, the user has to manually ensure that the final model remains functionally valid. We claim that certain symmetric functional arrangements (sFarr-s), which are special arrangements among symmetrically related substructures, bear close relation to object functions. Hence, we propose a purely geometric approach based on such substructures to match, replace, and position triplets of parts to create non-trivial, yet functionally plausible, model variations. We demonstrate that starting even from a small set of models such a simple geometric approach can produce a diverse set of non-trivial and plausible model variations. © 2013 The Author(s) Computer Graphics Forum © 2013 The Eurographics Association and Blackwell Publishing Ltd.

    A clever argument purports to show that we can directly perceive the emotions of others: (1) some emotional expressions are parts of the emotions they express; (2) in perceiving a part of something, one can perceive the whole; (3) therefore, in perceiving some emotional expressions, one can perceive the emotions they express. My aim in this paper is to assess the extent to which contemporary theories of emotion support the first premise of this argument. Copyright © 2017 Elsevier Inc. All rights reserved.

  1. Magnetic self-assembly of small parts

    Science.gov (United States)

    Shetye, Sheetal B.

    Modern society's propensity for miniaturized end-user products is compelling electronic manufacturers to assemble and package different micro-scale, multi-technology components in more efficient and cost-effective manners. As the size of the components gets smaller, issues such as part sticking and alignment precision create challenges that slow the throughput of conventional robotic pick-n-place systems. As an alternative, various self-assembly approaches have been proposed to manipulate micro to millimeter scale components in a parallel fashion without human or robotic intervention. In this dissertation, magnetic self-assembly (MSA) is demonstrated as a highly efficient, completely parallel process for assembly of millimeter scale components. MSA is achieved by integrating permanent micromagnets onto component bonding surfaces using wafer-level microfabrication processes. Embedded bonded powder methods are used for fabrication of the magnets. The magnets are then magnetized using pulse magnetization methods, and the wafers are then singulated to form individual components. When the components are randomly mixed together, self-assembly occurs when the intermagnetic forces overcome the mixing forces. Analytical and finite element methods (FEM) are used to study the force interactions between the micromagnets. The multifunctional aspects of MSA are presented through demonstration of part-to-part and part-to-substrate assembly of 1 mm x 1mm x 0.5 mm silicon components. Part-to-part assembly is demonstrated by batch assembly of free-floating parts in a liquid environment with the assembly yield of different magnetic patterns varying from 88% to 90% in 20 s. Part-to-substrate assembly is demonstrated by assembling an ordered array onto a fixed substrate in a dry environment with the assembly yield varying from 86% to 99%. In both cases, diverse magnetic shapes/patterns are used to control the alignment and angular orientation of the components. A mathematical model is

  2. Prediction of Part Distortion in Die Casting

    Energy Technology Data Exchange (ETDEWEB)

    R. Allen Miller

    2005-03-30

    The die casting process is one of the net shape manufacturing techniques and is widely used to produce high production castings with tight tolerances for many industries. An understanding of the stress distribution and the deformation pattern of parts produced by die casting will result in less deviation from the part design specification, a better die design and eventually more productivity and cost savings. This report presents methods that can be used to simulate the die casting process in order to predict the deformation and stresses in the produced part and assesses the degree to which distortion modeling is practical for die casting at the current time. A coupled thermal-mechanical finite elements model was used to simulate the die casting process. The simulation models the effect of thermal and mechanical interaction between the casting and the die. It also includes the temperature dependant material properties of the casting. Based on a designed experiment, a sensitivity analysis was conducted on the model to investigate the effect of key factors. These factors include the casting material model, material properties and thermal interaction between casting and dies. To verify the casting distortion predictions, it was compared against the measured dimensions of produced parts. The comparison included dimensions along and across the parting plane and the flatness of one surface.

  3. Tactile mental body parts representation in obesity.

    Science.gov (United States)

    Scarpina, Federica; Castelnuovo, Gianluca; Molinari, Enrico

    2014-12-30

    Obese people׳s distortions in visually-based mental body-parts representations have been reported in previous studies, but other sensory modalities have largely been neglected. In the present study, we investigated possible differences in tactilely-based body-parts representation between an obese and a healthy-weight group; additionally we explore the possible relationship between the tactile- and the visually-based body representation. Participants were asked to estimate the distance between two tactile stimuli that were simultaneously administered on the arm or on the abdomen, in the absence of visual input. The visually-based body-parts representation was investigated by a visual imagery method in which subjects were instructed to compare the horizontal extension of body part pairs. According to the results, the obese participants overestimated the size of the tactilely-perceived distances more than the healthy-weight group when the arm, and not the abdomen, was stimulated. Moreover, they reported a lower level of accuracy than did the healthy-weight group when estimating horizontal distances relative to their bodies, confirming an inappropriate visually-based mental body representation. Our results imply that body representation disturbance in obese people is not limited to the visual mental domain, but it spreads to the tactilely perceived distances. The inaccuracy was not a generalized tendency but was body-part related. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  4. “Hombre, brazo, bomba!”. Discussing the Anarchist Violence in Buenos Aires (1890-1910

    Directory of Open Access Journals (Sweden)

    Diego Gabriel Echezarreta

    2015-06-01

    Full Text Available Between 1890 and 1910, first as fear and later as a reality, anarchist attacks made its appearance in Buenos Aires. There are several questions about these phenomenons: How can they be understood? How should they be categorized? What caused them and how were they presented by the anarchist press? In this paper, a research of primary resources will lead us to examine the categories that are frequently used to describe these attempts: “political terrorism”, “propaganda by the deed”, “vindictive acts”. We will question the historiographical appropriateness of the categories “terrorism” and “propaganda by the deed”, concepts that anticipate the existence of a political aim in these events. We will verify that Anarchist attacks were driven by a passionate impulse, rather than political revolutionary motivations: they were acts of revenge with no intention of spreading the revolutionary message, but to murder those thought of being responsible for repression and injustice. Additionally, we will observe that the passionate perception prevailed also in the Libertarian press, and even though the attacks were celebrated, it was because they were acts of vengeance, and not because they were revolutionary.

    The cooling system of high-density thermal power requires fluids of high thermal conductivity, such as liquid metals. Electromagnetic pumps can be used to liquid metal fluid flow control in cooling circuits. The operation of electromagnetic pumps used to flow control is based on Lorentz force. This force can be achieved by magnetic field and electric current interaction, controlled by external independent power supplies. This work presents the electromagnetic pump operational principles, the IEAv development scheme and the BEMC-1 simulation code. The theoretical results of BEMC-1 simulation are compared to electromagnetic pump operation experimental data, validating the BEMC-1 code. This code is used to evaluate the DC electromagnetic pump performance applied to Mercury flow control and others liquid metal such as Sodium, Lead and Bismuth, used in nuclear fast reactors.

    Early studies have indicated an improved efficiency in Wind Energy Conversion Systems (WECS) to pumping water using centrifugal pumps supplied by wind generators with intermediate electrical power transmission. In these cases, the good matching between the wind rotor and the pump is added by some control strategies that provide stability and efficiency. In this work, the design aspects are discussed and some control strategies are analysed. The useful wind power, the output flow and overall efficiency are determined as function of wind velocity and the behavior of WECS is evaluated considering the local wind probability distribution.

    2016-12-14

    Accurate and precise density measurements by hydrostatic weighing requires the use of an analytical balance, configured with a suspension system, to both measure the weight of a part in water and in air. Additionally, the densities of these liquid media (water and air) must be precisely known for the part density determination. To validate the accuracy and precision of these measurements, uncertainty statements are required. The work in this report is a revision of an original report written more than a decade ago, specifically applying principles and guidelines suggested by the Guide to the Expression of Uncertainty in Measurement (GUM) for determining the part density uncertainty through sensitivity analysis. In this work, updated derivations are provided; an original example is revised with the updated derivations and appendix, provided solely to uncertainty evaluations using Monte Carlo techniques, specifically using the NIST Uncertainty Machine, as a viable alternative method.

    2013-12-01

    We explore how and to what extent prescription drug insurance expansions affect incentives for pharmaceutical advertising. When insurance expansions make markets more profitable, firms respond by boosting advertising. Theory suggests this effect will be magnified in the least competitive drug classes, where firms internalize a larger share of the benefits from advertising. Empirically, we find that the implementation of Part D coincides with a 14-19% increase in total advertising expenditures. This effect is indeed concentrated in the least competitive drug classes. The additional advertising raised utilization among non-elderly patients outside the Part D program by about 3.6%. This is roughly half of the direct utilization effect of Part D on elderly beneficiaries. The results suggest the presence of considerable spillover effects from publicly subsidized prescription drug insurance on the utilization and welfare of consumers outside the program.

    1979-01-01

    A new part length rod is provided. It may be used to control xenon induced power oscillations but to contribute to shutdown reactivity when a rapid shutdown of the reactor is required. The part length rod consists of a control rod with three regions. The lower control region is a longer weaker active portion separated from an upper stronger shorter poison section by an intermediate section which is a relative non-absorber of neutrons. The combination of the longer weaker control section with the upper high worth poison section permits the part length rod of this to be scrammed into the core when a reactor shutdown is required but also permits the control rod to be used as a tool to control power distribution in both the axial and radial directions during normal operation

    All nurses should have an understanding of heart sounds and be proficient in cardiac auscultation. Unfortunately, this skill is not part of many nursing school curricula, nor is it necessarily a required skillfor employment. Yet, being able to listen and accurately describe heart sounds has tangible benefits to the patient, as it is an integral part of a complete cardiac assessment. In this two-part article, I will review the fundamentals of cardiac auscultation, how cardiac anatomy and physiology relate to heart sounds, and describe the various heart sounds. Whether you are a beginner or a seasoned nurse, it is never too early or too late to add this important diagnostic skill to your assessment tool kit.

  18. Parts Quality Management: Direct Part Marking of Data Matrix Symbol for Mission Assurance

    Science.gov (United States)

    Moss, Chantrice; Chakrabarti, Suman; Scott, David W.

    2013-01-01

    A United States Government Accountability Office (GAO) review of twelve NASA programs found widespread parts quality problems contributing to significant cost overruns, schedule delays, and reduced system reliability. Direct part marking with Data Matrix symbols could significantly improve the quality of inventory control and parts lifecycle management. This paper examines the feasibility of using direct part marking technologies for use in future NASA programs. A structural analysis is based on marked material type, operational environment (e.g., ground, suborbital, Low Earth Orbit), durability of marks, ease of operation, reliability, and affordability. A cost-benefits analysis considers marking technology (label printing, data plates, and direct part marking) and marking types (two-dimensional machine-readable, human-readable). Previous NASA parts marking efforts and historical cost data are accounted for, including inhouse vs. outsourced marking. Some marking methods are still under development. While this paper focuses on NASA programs, results may be applicable to a variety of industrial environments.

    Since the invention of modern Additive Manufacturing (AM) processes engineers and designers have worked hard to capitalize on the unique building capabilities that AM allows. By being able to customize the interior fill of parts it is now possible to design components with a controlled density and customized internal structure. The creation of new polymers and polymer composites allow for even greater control over the mechanical properties of AM parts. One of the key reasons to explore AM, is to bring about a new paradigm in part design, where materials can be strategically optimized in a way that conventional subtractive methods cannot achieve. The two processes investigated in my research were the Fused Deposition Modeling (FDM) process and the Direct Ink Write (DIW) process. The objectives of the research were to determine the impact of in-fill density and morphology on the mechanical properties of FDM parts, and to determine if DIW printed samples could be produced where the filament diameter was varied while the overall density remained constant.

    2007-01-01

    Correct functioning of the entire stomatognathic system is achieved by a compatible relationship of all its parts. Four determinants, by their mutual harmonious activity, dictate the function of the entire system: the teeth, periodontium with supporting structure, muscles, temporomandibular joint (TMJ) and CNS. In such a complex system a disorder of any integrative part causes disturbances also in other parts of the system. Changed functions can arise through organic disorder, and also iatrogenically by inadequate conservative, prosthetic, surgical or orthodontic therapy. For this reason it is often difficult to recognise the primary cause. The first responses of the system to the disorder are adaptive mechanisms which occur within one or more integrative parts, and depending on their intensity and duration symptoms grow more prominent. Tissue response can be ortho- or parafunctional. Attempts are made to exclude psychoemotional influences and the obstacle eliminated by either abrasion, clenching or grinding of the teeth. If the obstacle is not eliminated by abrasion, the cause of such functional disorder becomes the trigger for parafunctional activity. From a review of the relevant literature it can be concluded that parafunctional activity is caused by changed occlusion, with determined psychological habits of the patient and specific tissue response of the stomatognathic system. Therefore, therapy of these disorders is made more difficult and includes a multidisciplinary approach.

    2012-01-01

    hypothesis of the existence of phenomenon change trends, the next step in the methodology of forecasting is the determination of a specific growth curve that describes the regularity of the development in time. These curves of growth are obtained by the analytical representation (expression of dynamic lines. There are two basic stages in the process of expression and they are: - The choice of the type of curve the shape of which corresponds to the character of the dynamic order variation - the determination of the number of values (evaluation of the curve parameters. The most widespread method of forecasting is the trend extrapolation. The basis of the trend extrapolation is the continuing of past trends in the future. The simplicity of the trend extrapolation process, on the one hand, and the absence of other information on the other hand, are the main reasons why the trend extrapolation is used for forecasting. The trend extrapolation is founded on the following assumptions: - The phenomenon development can be presented as an evolutionary trajectory or trend, - General conditions that influenced the trend development in the past will not undergo substantial changes in the future. Spare parts demand forecasting is constantly being done in all warehouses, workshops, and at all levels. Without demand forecasting, neither planning nor decision making can be done. Demand forecasting is the input for determining the level of reserve, size of the order, ordering cycles, etc. The question that arises is the one of the reliability and accuracy of a forecast and its effects. Forecasting 'by feeling' is not to be dismissed if there is nothing better, but in this case, one must be prepared for forecasting failures that cause unnecessary accumulation of certain spare parts, and also a chronic shortage of other spare parts. All this significantly increases costs and does not provide a satisfactory supply of spare parts. The main problem of the application of this model is that each

Direct part-marking with Data Matrix symbols could significantly improve the quality of inventory control and parts lifecycle management. This paper examines the feasibility of using 15 marking technologies for use in future NASA programs. A structural analysis is based on marked material type, operational environment (e.g., ground, suborbital, orbital), durability of marks, ease of operation, reliability, and affordability. A cost-benefits analysis considers marking technology (data plates, label printing, direct part marking) and marking types (two-dimensional machine-readable, human-readable). Previous NASA parts marking efforts and historical cost data are accounted for, including in-house vs. outsourced marking. Some marking methods are still under development.

    The Siting Guidelines, 10 CFR Part 960, have played a major role in the U.S. Department of Energy's (the Department) Office of Civilian Radioactive Waste Management siting program since their development and implementation in response to the Nuclear Waste Policy Act of 1982. According to the Act, the Siting Guidelines were applicable to the selection of sites for characterization. The Nuclear Waste Policy Amendments Act of 1987 (the Amendments Act) has selected the Yucca Mountain, Nevada, site for characterization from among those nominated according to the Siting Guidelines. Thus, the Amendments Act has taken the repository program beyond the phase of Siting Guidelines applicability, making the U.S. Nuclear Regulatory Commission's 10 CFR Part 60 the applicable regulation. However, the Department has chosen to make use of aspects of the Siting Guidelines in the Site Characterization Plan for the Yucca Mountain Site. (author) 4 figs., 11 refs

    Jastrow, R.; Nierenberg, W.; Seitz, F.

    1992-01-01

    The spectre of major climate change caused by the greenhouse effect has generated intensive research, heated scientific debate and a concerted international effort to draft agreements for the reduction of greenhouse gas emissions. This report of Scientific Perspectives on the greenhouse problem explains the technical issues in the debate in language readily understandable to the non-specialist. The inherent complexities of attempts to simulate the earth's climate are explained, particularly with regard to the effects of clouds and the circulation of the oceans, which together represent the largest factors of uncertainty in current global warming forecasts. Results of the search for the 'greenhouse signal' in existing climate records aredescribed in chapter 3 (part two). Chapter 5 (part two) develops a projection of 21st-century warming based on relatively firm evidence of the earth's actual response to known increases in greenhouse gas emissions during the last 100 years

    Cellulite is a topographic skin change that is nearly ubiquitous in postpubertal women. Treatment remains elusive. The various treatments currently available are only partially or temporarily effective. Newer therapeutic modalities continue to evolve without much understanding of the complex nature of cellulite. The successful treatment of cellulite will ultimately depend upon our understanding of the pathophysiology of cellulite adipose tissue. Part I of this two-part series on cellulite reviews how the concept and perception of cellulite has evolved over time and its proposed etiologies. The article also focuses on the physiology of human adipose tissue, particularly regarding cellulite. Copyright 2009 American Academy of Dermatology, Inc. Published by Mosby, Inc.

    International Nuclear Information System (INIS)

    Wunsch, R.; Rohden, L. von; Cleaveland, R.; Aumann, V.

    2014-01-01

    Small-part sonography refers to the display of small, near-surface structures using high-frequency linear array transducers. Traditional applications for small part ultrasound imaging include visualization and differential diagnostic evaluation in unclear superficial bodily structures with solid, liquid and mixed texture, as well as similar structures in nearly superficial organs such as the thyroid glands and the testes. Furthermore indications in the head and neck regions are the assessment of the outer CSF spaces in infants, the sonography of the orbit, the sonography of the walls of the large neck vessels, the visualization of superficially situated lymph nodes and neoplasms. Clinical evidence concludes that sonography, having of all imaging modalities the highest spatial resolution in the millimeter- and micrometer range (100–1000 μm), can be considered the best suited technique for examining superficial pathological formations and near-surface organs. In addition, it delivers important information about characteristic, often pathognomonic tissue architecture in pathological processes

    2014-03-01

    Full Text Available Neurofibromatoses (NF are a group of genetic multiple tumor growing predisposition diseases: neurofibromatosis type 1 (NF1, neurofibromatosis type 2 (NF2 and schwannomatosis (SCH, which have in common the neural origin of tumors and cutaneous signs. They affect nearly 80 thousand of Brazilians. In recent years, the increased scientific knowledge on NF has allowed better clinical management and reduced complication morbidity, resulting in higher quality of life for NF patients. In most cases, neurology, psychiatry, dermatology, clinical geneticists, oncology and internal medicine specialists are able to make the differential diagnosis between NF and other diseases and to identify major NF complications. Nevertheless, due to its great variability in phenotype expression, progressive course, multiple organs involvement and unpredictable natural evolution, NF often requires the support of neurofibromatoses specialists for proper treatment and genetic counseling. This Part 1 offers step-by-step guidelines for NF differential diagnosis. Part 2 will present the NF clinical management.

    Full Text Available The author analyzes the ways in which globalization has reconfigured patterns of migration. In addition to entire communities displaced within and outside of Colombia's borders, migratory patterns revolve around flight, exile or the movement of body parts, including legs, brains and reproductive organs. This text addresses distinct types of work and the bodily transactions that each entails when migration occurs; it then explores the consequent visibility or invisibility and resulting legalization or illegality of the re-location of different body parts and the creation of new spaces.

Furthermore indications in the head and neck regions are the assessment of the outer CSF spaces in infants, the sonography of the orbit, the sonography of the walls of the large neck vessels, the visualization of superficially situated lymph nodes and neoplasms. Clinical evidence concludes that sonography, having of all imaging modalities the highest spatial resolution in the millimeter- and micrometer range (100–1000 μm), can be considered the best suited technique for examining superficial pathological formations and near-surface organs. In addition, it delivers important information about characteristic, often pathognomonic tissue architecture in pathological processes.

    Fu, Louis

    2010-03-01

    In this second part of ancient Chinese surgical history, the practice of bone setting in China began around 3000 years ago. Throughout this period, significant progress was made, some highlights of which are cited. These methods, comparable with Western orthopaedic technique, are still being practised today. In conclusion, the possible reasons for the lack of advancement in operative surgery are discussed, within context of the cultural, social and religious background of ancient China.

    Sovrano, Valeria Anna; Bisazza, Angelo

    2008-01-01

    The ability to visually complete partly occluded objects (so-called "amodal completion") has been documented in mammals and birds. Here, we report the first evidence of such a perceptual ability in a fish species. Fish (Xenotoca eiseni) were trained to discriminate between a complete and an amputated disk. Thereafter, the fish performed test trials in which hexagonal polygons were either exactly juxtaposed or only placed close to the missing sectors of the disk in order to produce or not produce the impression (to a human observer) of an occlusion of the missing sectors of the disk by the polygon. In another experiment, fish were first trained to discriminate between hexagonal polygons that were either exactly juxtaposed or only placed close to the missing sectors of a disk, and then tested for choice between a complete and an amputated disk. In both experiments, fish behaved as if they were experiencing visual completion of the partly occluded stimuli. These findings suggest that the ability to visually complete partly occluded objects may be widespread among vertebrates, possibly inherited in mammals, birds and fish from early vertebrate ancestors.

  10. The metallurgy of superalloys part 2

    International Nuclear Information System (INIS)

    Abdelazim, M.E.; Hammad, F.H.

    1990-01-01

    This is part II of the report titled 'the metallurgy of superalloys'. It deals with the effect of heat treatment and operating conditions (thermal exposure and environment) on the mechanical properties of superalloys. The heat treatment is important in the development of superalloys through that it controls type, amount, size shape and distribution of the precipitate and the grain size of the matrix. The thermal exposure leads to reduction in the amount of the primary carbides and to precipitation of secondary carbides. Also it leads to the agglomeration and coarsening of gamma or the transformation of gamma phase to phase. The environment may lead to the internal oxidation, carburization, decarburization or sulphidization of the superalloys which may result in the degradation of their mechanical properties. This part gives also an example of applications of superalloys in the field of nuclear reactors especially high temperature-gas cooled reactors. Joined with this part a table which contains the major superalloys including its chemical analysis, creep rupture strength and some of its applications. 1 tab

  11. Career anchors and learning plan (part one

    Directory of Open Access Journals (Sweden)

    Daniela Brečko

    2006-12-01

    Full Text Available The article is divided into three parts. The first part concentrates on how important career is for an individual, organization and society. The author establishes that understanding of career has changed dramatically and does not only refer to climbing up the career ladder, but also moving off or even down the career ladder. The notion of career, as a lifelong and professional path, encompasses all aspects of human personality and their roles acquired through one's life. On basis of vast and longitudinal research, where the author has studied career anchors of individuals, it is the objective of the author to find out on basis of what grounds do the individuals decide to take certain directions in their careers and how learning contributes to such decisions. As a source the author has used Shein's theory of career anchors. Part one describes in greater detail 8 different career anchors and introduces their main features with the findings of the research, which refer to the analysis of professions (work positions and established career anchors. The author thus verifies the hypothesis that career anchors do exist in our area.

    This research tries to make advancement in GPS signal processing to estimate the interseismic vertical deformation field at western part of Sumatra Island. The data derived by Continuous Global Positioning System (CGPS) from Badan Informasi Geospasial (BIG) between 2010 and 2012. GPS Analyze at Massachusetts Institute of Technology (GAMIT) software and Global Kalman Filter (GLOBK) software are used to process the GPS signal to estimate the vertical velocities of the CGPS station. In order to minimize noise due to atmospheric delay, Vienna Mapping Function 1 (VMF1) is used as atmospheric parameter model and include daily IONEX file provided by the Center for Orbit Determination in Europe (CODE) as well. It improves GAMIT daily position accuracy up to 0.8 mm. In a second step of processing, the GLOBK is used in order to estimate site positions and velocities in the ITRF08 reference frame. The result shows that the uncertainties of estimated displacement velocity at all CGPS stations are smaller than 1.5 mm/yr. The subsided deformation patterns are seen at the northern and southern part of west Sumatra. The vertical deformation at northern part of west Sumatra indicates postseismic phase associated with the 2010 and 2012 Northern Sumatra earthquakes and also the long-term postseismic associated with the 2004 and 2005 Northern Sumatra earthquakes. The uplifted deformation patterns are seen from Bukit Tinggi to Seblat which indicate a long-term interseismic phase after the 2007 Bengkulu earthquake and 2010 Mentawai earthquake. GANO station shows a subsidence at rate 12.25 mm/yr, indicating the overriding Indo-Australia Plate which is dragged down by the subducting Southeast Asian Plate.

    Full Text Available Alveolar soft-part sarcoma (ASPS is an extremely rare disease arising from connective tissues with a propensity for recurrence and metastasis. Clinically, it can be confused with hemangioma or arterio-venous malformations. Thus, a high index of suspicion and histopathological examination are required to make a definitive diagnosis. We report a case of recurrent ASPS in a young female with multiple sites involvement without any features of metastasis who has been treated with excision of the symptomatic lesions followed by chemotherapy.

    2009-12-01

    Although surgery was an accepted and quite proficient craft very early on in Chinese history, it has deteriorated through the ages. Despite the fact that anaesthetic agents in major surgery were employed during the third century, Chinese surgery is conspicuous by its stagnation. Reverence for the dead, filial piety, abhorrence of shedding blood and other conservative attitudes make it impossible for any accurate knowledge of the human anatomy and physiology, without which surgery cannot progress. This article surveys some highlights in the history of surgery in ancient China and examines the factors responsible for its decline. The second concluding part deals with orthopaedics.

    Semanov, G.; Volkov, V.; Somkin, V.; Iljushenko-Krylov, D.

    1997-12-31

    A higher degree of ecological safety in ship traffic depends on onboard measures as well as reception facilities on shore, treatment of ship generated wastes and preparedness for combating emergency oil spills. The problem is particularly acute in the North Sea Route (NSR) due to high vulnerability of the Arctic ecosystems, low rates of natural degradation of oil, absence of forward coastal infrastructure, low efficiency of oil combating means in ice conditions and severe climatic conditions. Oil spills in the NSR are likely to occur as the offshore production and transportation of oil increase. Therefore a regional Oil Spill Contingency Plan (OSCP) is being constructed and developed on 3 levels: 1) Development of concept, definition of response organisations and their technical ability (Part I). 2) Collection and analysis of information, development of scenarios of probable oil spills, clearing of the funding mechanism and basis for additional outside co-operation from other Russian regions and circumpolar countries (part II). 3) Development of NSR OSCP (part III). The present report (part I) provides the plan concept, rescue organisations and data on types and amounts of the oil spill combating technical means and of the floating facilities available in the NSR or it`s vicinity. The concept takes into account subdivision of the Route, interaction and links between responsible organisations, realities of the Russian Arctic such as transport, communications, energy, labour resources etc. and requirements of the IMO and of the International Convention OPRC 90. According to Russian legislation implementation of combating operations at sea is the responsibility of the Maritime Pollution Control and Salvage Administration that consists of a Central Administration and basin emergency divisions situated in Murmansk and Nahodka.

    Smith, Jr., Joseph L.; Kirtley, Jr., James L.

    1981-01-01

    A rotating electric machine in which the armature winding thereof and other parts are supported by a liquid to withstand the mechanical stresses applied during transient overloads and the like. In particular, a narrow gap is provided between the armature winding and the stator which supports it and this gap is filled with an externally pressurized viscous liquid. The liquid is externally pressurized sufficiently to balance the static loads on the armature winding. Transient mechanical loads which deform the armature winding alter the gap dimensions and thereby additionally pressurize the viscous liquid to oppose the armature winding deformation and more nearly uniformly to distribute the resulting mechanical stresses.

    Full Text Available Los invernaderos son utilizados para muchas aplicaciones, no solo cultivos. Invernaderos automatizados requieren de un controlador que abra y cierre mallas reduciendo la radiación incidente evitando una evapotranspiración excesiva del cultivo. Este trabajo contempla el desarrollo de un controlador de mallas y de irrigación aplicada en función a la radiación incidente ahorrando 35% de agua en tiempo de lluvias; con nubes o con la radiación lunar nocturna no se enciende la bomba. Las mallas permanecían cerradas durante la noche abriéndose al amanecer cuando la radiación era baja. En el experimento realizado con tomates dentro de un invernadero se utilizaron meses intercalados para analizar la operación manual de mallas y la operación automática de las mismas. La radiación incidente en las plantas fue máxima en Mayo y Agosto meses en que no se usaron mallas de sombreo. En Agosto la temperatura del aire aumentó arriba de 28°C reduciendo en un 50% el tamaño de las frutas. La temperatura de los frutos disminuyó 2.5°C con el uso de mallas reduciendo el agrietamiento en el tomate.

    2014-01-01

    Appropriate management of temporomandibular disorders (TMD) requires an understanding of the underlying dysfunction associated with the temporomandibular joint (TMJ) and surrounding structures. A comprehensive examination process, as described in part 1 of this series, can reveal underlying clinical findings that assist in the delivery of comprehensive physical therapy services for patients with TMD. Part 2 of this series focuses on management strategies for TMD. Physical therapy is the preferred conservative management approach for TMD. Physical therapists are professionally well-positioned to step into the void and provide clinical services for patients with TMD. Clinicians should utilize examination findings to design rehabilitation programs that focus on addressing patient-specific impairments. Potentially appropriate plan of care components include joint and soft tissue mobilization, trigger point dry needling, friction massage, therapeutic exercise, patient education, modalities, and outside referral. Management options should address both symptom reduction and oral function. Satisfactory results can often be achieved when management focuses on patient-specific clinical variables. PMID:24976744

    Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals - including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years.

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available The pathologies of tendon and ligament attachments are called enthesopathies. One of its types is enthesitis which is a characteristic sign of peripheral spondyloarthropathy. Clinical diagnosis of enthesitis is based on rather non-specific clinical signs and results of laboratory tests. Imaging examinations are highly promising. Numerous publications prove that enthesitis can be differentiated from other enthesopathic processes in an ultrasound examination or magnetic resonance imaging. However, some reports indicate the lack of histological criteria, specific immunological changes and features in imaging examinations that would allow the clinical diagnosis of enthesitis to be confirmed. The first part of the publication presents theories on the etiopathogenesis of enthesopathies: inflammatory, mechanical, autoimmune, genetic and associated with the synovio-entheseal complex, as well as theories on the formation of enthesophytes: infl ammatory, molecular and mechanical. The second part of the paper is a review of the state-of-the-art on the ability of imaging examinations to diagnose enthesitis. It indicates that none of the criteria of inflammation used in imaging medicine is specific for this pathology. As enthesitis may be the only symptom of early spondyloarthropathy (particularly in patients with absent HLA-B27 receptor, the lack of its unambiguous picture in ultrasound and magnetic resonance scans prompts the search for other signs characteristic of this disease and more specific markers in imaging in order to establish diagnosis as early as possible.

    2013-03-01

    Full Text Available Visualisation is becoming increasingly important for understanding information, such as investigative data (for example: computing, medical and crime scene evidence and analysis (for example: network capability assessment, data file reconstruction and planning scenarios. Investigative data visualisation is used to reconstruct a scene or item and is used to assist the viewer (who may well be a member of the general public with little or no understanding of the subject matter to understand what is being presented. Analysis visualisations, on the other hand, are usually developed to review data, information and assess competing scenario hypotheses for those who usually have an understanding of the subject matter. Visualisation represents information that has been digitally recorded (for example: pictures, video and sound, hand written and/or spoken data, to show what may have, could have, did happen or is believed to have happened. That is why visualising data is an important development in the analysis and investigation realms, as visualisation explores the accuracies, inconsistencies and discrepancies of the collected data and information. This paper presents introduces some of the various graphical techniques and technology used to display digital information in a courtroom. The advantages and disadvantages involved in the implementation of this technology are also discussed. This paper is part one of a two part series that aims to describe the use of, and provide guidelines for, the use of graphical displays in courtrooms.

    Science.gov (United States)

    Chaney, Kristin P; Macik, Maria L; Turner, Jacqueline S; Korich, Jodi A; Rogers, Kenita S; Fowler, Debra; Scallan, Elizabeth M; Keefe, Lisa M

    Curricular review is considered a necessary component for growth and enhancement of academic programs and requires time, energy, creativity, and persistence from both faculty and administration. At Texas A&M College of Veterinary Medicine & Biomedical Sciences (TAMU), the faculty and administration partnered with the university's Center for Teaching Excellence to create a faculty-driven, data-enhanced curricular redesign process. The 8-step process begins with the formation of a dedicated faculty curriculum design team to drive the redesign process and to support the college curriculum committee. The next steps include defining graduate outcomes and mapping the current curriculum to identify gaps and redundancies across the curriculum. Data are collected from internal and external stakeholders including veterinary students, faculty, alumni, and employers of graduates. Data collected through curriculum mapping and stakeholder engagement substantiate the curriculum redesign. The guidelines, supporting documents, and 8-step process developed at TAMU are provided to assist other veterinary schools in successful curricular redesign. This is the first of a two-part report that provides the background, context, and description of the process for charting the course for curricular change. The process involves defining expected learning outcomes for new graduates, conducting a curriculum mapping exercise, and collecting stakeholder data for curricular evaluation (steps 1-4). The second part of the report describes the development of rubrics that were applied to the graduate learning outcomes (steps 5-8) and engagement of faculty during the implementation phases of data-driven curriculum change.

  13. Short history of PACS (Part II: Europe)

    2011-01-01

    Although the concept of picture archiving and communications systems (PACS) was developed in Europe during the latter part of the 1970s, no working system was completed at that time. The first PACS implementations took place in the United States in the early 1980s, e.g. at Pennsylvania University, UCLA, and Kansas City University. Some more or less successful PACS developments also took place in Europe in the 1980s, particularly in the Netherlands, Belgium, Austria, the United Kingdom, France, Italy, Scandinavia, and Germany. Most systems could be characterized by their focus on a single department, such as radiology or nuclear medicine. European hospital-wide PACS with high visibility evolved in the early 1990s in London (Hammersmith Hospital) and Vienna (SMZO). These were followed during the latter part of the 1990s by approximately 10-20 PACS installations in each of the major industrialized countries of Europe. Wide-area PACS covering several health care institutions in a region are now in the process of being implemented in a number of European countries. Because of limitations of space some countries, for example, Denmark, Finland, Spain, Greece, as well as Eastern European countries, etc. could not be appropriately represented in this paper.

  14. Study of laser cladding nuclear valve parts

    1998-12-01

    The mechanism of laser cladding is discussed by using heat transfer model of laser cladding, heat conduction model of laser cladding and convective transfer mass model of laser melt-pool. Subsequently the laser cladding speed limit and the influence of laser cladding parameters on cladding layer structure is analyzed. A 5 kW with CO 2 transverse flow is used in the research for cladding treatment of sealing surface of stop valve parts of nuclear power stations. The laser cladding layer is found to be 3.0 mm thick. The cladding surface is smooth and has no such defects as crack, gas pore, etc. A series of comparisons with plasma spurt welding and arc bead welding has been performed. The results show that there are higher grain grade and hardness, lower dilution and better performances of resistance to abrasion, wear and of anti-erosion in the laser cladding layer. The new technology of laser cladding can obviously improve the quality of nuclear valve parts. Consequently it is possible to lengthen the service life of nuclear valve and to raise the safety and reliability of the production system

    2004-01-01

    Integrating autonomous disciplines into a problem amenable to solution presents a major challenge in realistic multidisciplinary design optimization (MDO). We propose a linguistic approach to MDO problem description, formulation, and solution we call reconfigurable multidisciplinary synthesis (REMS). With assistance from computer science techniques, REMS comprises an abstract language and a collection of processes that provide a means for dynamic reasoning about MDO problems in a range of contexts. The approach may be summarized as follows. Description of disciplinary data according to the rules of a grammar, followed by lexical analysis and compilation, yields basic computational components that can be assembled into various MDO problem formulations and solution algorithms, including hybrid strategies, with relative ease. The ability to re-use the computational components is due to the special structure of the MDO problem. The range of contexts for reasoning about MDO spans tasks from error checking and derivative computation to formulation and reformulation of optimization problem statements. In highly structured contexts, reconfigurability can mean a straightforward transformation among problem formulations with a single operation. We hope that REMS will enable experimentation with a variety of problem formulations in research environments, assist in the assembly of MDO test problems, and serve as a pre-processor in computational frameworks in production environments. Part 1 of two companion papers, discusses the fundamentals of REMS. This paper, Part 2 illustrates the methodology in more detail.

    Full Text Available El vacío de poder producido por el derrumbe del Imperio Romano dejó a la Europa Medieval sumida en un ambiente de luchas. La dominante Iglesia Cristiana de Roma batalló para extenderse y someter a reyes y emperadores. La autoridad del papa Cristiano de Roma realizó un esfuerzo para esclavizar al pensamiento de los creyentes religiosos a la cerrada perspectiva religiosa que se tenía en esas épocas. Sin embargo, fue desde el seno mismo de los fieles de donde surgió la necesidad de ver a la naturaleza y sus leyes de otra manera. El descubrimiento, traducción y difusión de los textos de los pensadores griegos clásicos, permitió iniciar el proceso de independencia del pensamiento europeo, lo que llevó al surgimiento del Renacimiento y la Ilustración. Fue entonces cuando comenzó a utilizase el método inductivo en el afán de encontrar otras maneras de interpretar a la naturaleza y avanzar en el conocimiento. Así, durante el siglo XVI la alquimia fue cuestionada y aparecieron los primeros escritos de una metalurgia empírica, considerados la base de la ciencia moderna; durante el XVII, aún con la existencia de conceptos alquímicos residuales, algunos personajes comenzaron a realizar experimentos, con lo que se establecieron las primeras hipótesis sobre los conceptos y fenómenos químicos clave, los cuales sirvieron de sustento para desarrollar al pensamiento lógico y racional del siglo XVIII, como el relativo a las afinidades, que se basaba en las relaciones entre las sustancias, observadas durante la formación de compuestos y como una analogía de las relaciones humanas. Los trabajos publicados entonces sobre los elementos del proceso del pensamiento, permitieron consolidar los conceptos base relativos al enlace y otros a él relacionados.

  1. Medicare Part D and Portfolio Choice.

    Science.gov (United States)

    Ayyagari, Padmaja; He, Daifeng

    2016-05-01

    This study evaluates the impact of medical expenditure risk on portfolio choice among the elderly. The risk of large medical expenditures can be substantial for elderly individuals and is only partially mitigated by access to health insurance. The presence of deductibles, copayments, and other cost-sharing mechanisms implies that medical spending risk can be viewed as an undiversifiable background risk. Economic theory suggests that increases in background risk reduce the optimal financial risk that an individual or household is willing to bear (Pratt and Zeckhauser 1987; Elmendorf and Kimball 2000). In this study, we evaluate this hypothesis by estimating the impact of the introduction of the Medicare Part D program, which significantly reduced prescription drug spending risk for seniors, on portfolio choice.

    International travels for tourism and business purposes continue to increase annually, while the global terrorism and the risk of lethal viral infections are currently real concerns. It is important that primary care physicians assess travel risk and adequately prepare the prospective traveler for trips. Appropriate vaccines should be administered and an emergency self-kit recommended. Patient should be educated about safe travel habits and a posttravel follow-up process established. Further, traveling healthcare professionals may be called upon to assist an ill patient at any time during their journey. In these 2-part special articles, we provide a practical brief summary of up-to-date travel medicine basics for primary care physicians.

    2009-01-01

    Karma Snyder, a project manager at NASA's John C. Stennis Space Center, was a senior design engineer on the RL10 liquid rocket engine that powered the Centaur, the upper stage of the rocket used in NASA's Lunar CRater Observation and Sensing Satellite (LCROSS) mission in October 2009. Part of the LCROSS mission was to search for water on the moon by striking the lunar surface with a rocket stage, creating a plume of debris that could be analyzed for water ice and vapor. Snyder's work on the RL10 took place from 1995 to 2001 when she was a senior design engineer with Pratt & Whitney Rocketdyne. Years later, she sees the project as one of her biggest accomplishments in light of the LCROSS mission. 'It's wonderful to see it come into full service,' she said. 'As one of my co-workers said, the original dream was to get that engine to the moon, and we're finally realizing that dream.'

    The structural modifications induced in a model of molten CuCl by quenching the chlorine component into a microporous disordered matrix are evaluated using the hypernetted-chain closure in Ornstein-Zernike relations for the pair distribution functions in random systems. Aside from obvious changes in the behaviour of long-wavelength density fluctuations, the main effect of partial quenching is an enhanced delocalization of the Cu + ions. The model suggests that the ionic mobility in a superionic glass is enhanced relative to the melt at the same temperature and density. Only very minor quantitative differences are found in the structural functions when the replica Ornstein-Zernike relations derived by Given and Stell for a partly quenched system are simplified to those given earlier by Madden and Glandt.

  7. Absorption chillers: Part of the solution

    International Nuclear Information System (INIS)

    Acid rain, ozone depletion, global warming, and implementation economics are considered as they relate to the advisability of expanding the application of absorption chillers. Introductory and background information are provided to put the discussion in the proper context. Then all four issues are discussed separately as they relate to absorption chillers. Acid rain and ozone depletion concerns, and implementation economics, are found to support the expanded use of absorption chillers. The global warming concern is found to be more of a gray area, but the areas of benefit correspond well with the conditions of greatest economic advantage. All things considered, absorption chillers are believed to be part of the environmental and economic solution. It is further believed that integrated resource planning (IRP) processes that consider electric and gas technologies on an equal footing would come to the same conclusion for many regions of the United States. 9 refs., 3 tabs

    Full Text Available Part 1 of this guideline addressed the differential diagnosis of the neurofibromatoses (NF: neurofibromatosis type 1 (NF1, neurofibromatosis type 2 (NF2 and schwannomatosis (SCH. NF shares some features such as the genetic origin of the neural tumors and cutaneous manifestations, and affects nearly 80 thousand Brazilians. Increasing scientific knowledge on NF has allowed better clinical management and reduced rate of complications and morbidity, resulting in higher quality of life for NF patients. Most medical doctors are able to perform NF diagnosis, but the wide range of clinical manifestations and the inability to predict the onset or severity of new features, consequences, or complications make NF management a real clinical challenge, requiring the support of different specialists for proper treatment and genetic counseling, especially in NF2 and SCH. The present text suggests guidelines for the clinical management of NF, with emphasis on NF1.

    1992-01-01

    During the previous period RA reactor was not operated because the Committee of Serbian ministry for health and social care has cancelled the operation licence in August 1984. The reason was the non existing emergency cooling system and lack of appropriate filters in the special ventilation system. Control and maintenance of the reactor instrumentation and tools was done regularly but dependent on the availability of the spare parts. In order to enable future reliable operation of the RA reactor, according to new licensing regulations, during 1991, three major tasks were fulfilled: building of the new emergency cooling system, reconstruction of the existing ventilation system, and renewal of the reactor power supply system. Renewal of the reactor instrumentation was started but but it is behind the schedule in 1991 because the delivery of components from USSR is late. Production of this instruments is financed by the IAEA according to the contract signed in December 1988 with Russian Atomenergoexport. According to this contract, it has been planned that the RA reactor instrumentation should be delivered to the Vinca Institute by the end of 1990. Since then any delivery of components to Yugoslavia was stopped because of the temporary embargo imposed by the IAEA for political reasons. In 1991 most of the existing RA reactor instrumentation was dismantled, only the part needed for basic measurements when reactor is not operated, was maintained. Training of the existing personnel was done regularly, but lack of financial support prevented employment of new workers that would be needed for operation in shifts and regular maintenance [sr

  19. Development of aero-engines, part I

    Energy Technology Data Exchange (ETDEWEB)

    Dehn, K.

    1943-01-01

    In the first part of a two-part paper on aero-engine development, Dehn gives an overview of engine types and configurations. The information includes graphic illustrations on performance and pictures of engines. Various configurations of engines depicted were radial, V, in-line, in-line opposed and an inverted V design. Pointing out steps which could be taken to increase engine efficiency, the author explains that by using faired, air-cooled power plants, a full 20% increase in power could be gained as compared to using a similar, water-cooled engine. More horsepower could be derived from engines operating at higher temperatures, but this presented heat problems on overheating at high rev's just before take-off and during climb-out to cruising altitude. Developments in fuel-injected and turbo-charged engines were much superior to carbureted systems in that service ceilings could be increased effectively. Also, described is a rather unusual aircraft power plant. This was the Junkers Jumo 205 aero-diesel which actually saw service. Each engine had six chambers, and each chamber contained two pistons, one suspended above the other. Real and theoretical heat loss in Otto motors as related to pressure and engine displacement was also subject to investigation. In his discussion, Dehn continually uses examples of both British and American aircraft engines as technological comparisons with German engines. At the end of this section it is mentioned that work on jet motors and newer developments had intentionally been excluded from the paper, apparently since details were not readily available.

    Computers are an integral part of modern radiology equipment. In the first half of this two-part article, we dwelt upon some fundamental concepts regarding computer hardware, covering components like motherboard, central processing unit (CPU), chipset, random access memory (RAM), and memory modules. In this article, we describe the remaining computer hardware components that are of relevance to radiology. “Storage drive” is a term describing a “memory” hardware used to store data for later retrieval. Commonly used storage drives are hard drives, floppy drives, optical drives, flash drives, and network drives. The capacity of a hard drive is dependent on many factors, including the number of disk sides, number of tracks per side, number of sectors on each track, and the amount of data that can be stored in each sector. “Drive interfaces” connect hard drives and optical drives to a computer. The connections of such drives require both a power cable and a data cable. The four most popular “input/output devices” used commonly with computers are the printer, monitor, mouse, and keyboard. The “bus” is a built-in electronic signal pathway in the motherboard to permit efficient and uninterrupted data transfer. A motherboard can have several buses, including the system bus, the PCI express bus, the PCI bus, the AGP bus, and the (outdated) ISA bus. “Ports” are the location at which external devices are connected to a computer motherboard. All commonly used peripheral devices, such as printers, scanners, and portable drives, need ports. A working knowledge of computers is necessary for the radiologist if the workflow is to realize its full potential and, besides, this knowledge will prepare the radiologist for the coming innovations in the ‘ever increasing’ digital future

    Recent Findings from Audits, New Technology Data Reviews a) Disabled Chip Burn-ins A recent audit for a QML device discovered that the chip was disabled during the static burn-in, thus it was not drawing any current. Recommendation: For new SMDs add a statement within the burn-in paragraphs stating that the parts shall be kept in their enabled state during the burn-in. b) Class Q 160-hr/125oC Burn-in This is being interpreted as a static burn-in (even for CMOS technology). Recommendation: Provide clarification in MIL-STD-883, Test Method 5004. c) At Frequency (Dynamic) Burn-ins Test equipment limitation is being cited for not doing burn-ins at the application frequency. Recommendation: The burn-in task group to discuss and provide guidance. When the SMD says that the part can be used at 200 MHz, then doing burn-in at 6 MHz (cited as burn-in equipment limitation frequency) is not going to be meaningful! d) Two Static Burn-ins Some manufacturers are doing electrical testing between the two static burn-ins, whereas others do electricals after completing both static burn-ins. Recommendation: Provide clarification in MIL-STD-883, Test Method 5004. e) Thermal Imaging For a device with hot spots, the thermal resistance, junction-to-case, would be much higher than the guidelines given in MIL-STD-1835. One of the suppliers used thermal imaging to find hot spots on the die. Recommendation: Assign a task group to evaluate the effectiveness of thermal imaging at the product development stage.

  5. Die Casting Part Distortion: Prediction and Attenuation

    Energy Technology Data Exchange (ETDEWEB)

    Dr, R. Allen Miller

    2002-02-12

    The goal of this research was to predict the part deformation and residual stresses after ejection from the die and cooling to room temperature. A finite element model was built to achieve this goal and several modeling techniques were investigated throughout this research. Die-casting is a very complex process and the researchers are faced with a large number of hard to solve physical problems when modeling the process. Several assumptions are made in our simulation model. The first significant assumption is the instantaneous cavity filling. This means that the cavity filling stage is not considered in our model. Considering the cavity filling stage increases the modeling complexity as a result of different flow patterns. expected in the shot sleeve, gate, runner and different cavity features. The flow of gas from the cavity through the vents is another problem that is ignored in our model as a result of this assumption. Our second assumption is that the cast metal has uniform temperature distribution inside the cavity, at the starting point of simulation. This temperature is assumed to be over liquidus limit, i.e. the solid fraction is 0.0% of the cast metal. The third assumption is due to ABAQUS (commercial software used in this research) limitations. ABAQUS cannot deal with multi-phase models; therefore we use solid elements to define the casting instead of multi-phase (liquid/solid) elements. Liquid elements can carry the hydrostatic pressure from the shot sleeve and apply it on the cavity surfaces, while the solid elements do not have this capability. To compensate for this assumption we add the cavity pressure as a boundary condition and apply it on the cavity surface separately from the part. Another issue with this assumption is that, liquid casting can follow the cavity shape when it distorts. With the use of solid elements to represent the casting during its liquid state, it loses this capability to follow the cavity. Several techniques were tested to

    2009-01-01

    The present work summarizes the more elucidating aspects on the foundations and the practice of the medicine in Antique Mesopotamia, since the invention of the writing, more than 5000 thousand years ago, and the beginning of our era. The first part of the article includes a brief perspective about the political and social evolution that characterized those archaic civilizations, as well as the inventions and knowledge further used by the following Humanity's generations. Most of what is known on the subject, as well as the history and political-social events that occurred in the region during that remote epoch, resulted of the laborious decoding of about half a million small clay plates or fragments with text engravings in cuneiform characters that were discovered since the middle of the XIX century in the ruins of the main cities of the Babylonian and Assyrian empires. The second part embraces exclusively the main characteristics of the medicine in Ancient Mesopotamia, in its main facets: concept of disease, healers and practice. The disease was considered a divine punishment or resultant from a malign influence. In that base, the medicine began by being preventive, by the use of appropriate amulets, or by offerings or sacrifices intending to pacify those malign forces. The treatment of the generality of the diseases privileged the expulsion of those spirits and malign influences from the patient body, purifying it, which was done by the specific intervention of an ãshipu (clergyman-exorcist); not having results, the treatment was continued by the asû (practical healer) that appealed to a group of physical manipulations, limited surgical acts and the administration or application of prescriptions, resultants of the mixture of organic and inorganic substances. In case of failing, the patients (as well as individuals or rein leaders) could fall back upon a priest diviner (bârû) who, by examination of the organs of an animal especially sacrificed for the effect

    2018-01-01

    The serratus anterior is portrayed as a homogeneous muscle in textbooks and during functional activities and rehabilitation exercises. It is unclear whether the serratus anterior is composed of subdivisions with distinctive morphology and functions. The purpose of this study was to determine whether the serratus anterior could be subdivided into different structural parts on the basis of its segmental architectural parameters. Eight formalin-embalmed serratus anterior muscles were dissected and the attachments of each fascicle documented. Orientation and size of each fascicle were measured and the physiological cross-sectional area (PCSA) calculated. Three subdivisions of the serratus anterior were identified. A new finding was the discovery of two distinctive fascicles attached to the superior and inferior aspects of rib 2. The rib 2 inferior fascicle had the largest PCSA (mean 1.6 cm 2 ) and attached, with the rib 3 fascicle, along the medial border of the scapula to form the middle division. The rib 2 superior and rib 1 fascicles attached to the superior angle of the scapula (upper division). Fascicles from ribs 4-8/9 attached to the inferior angle of the scapula (lower division). Mean fascicle angle relative to a vertical midline reference and PCSA for each division were 29° and 1.3 cm 2 (upper), 90° and 2.2 cm 2 (middle) and 59° and 3.0 cm 2 (lower). This novel study demonstrated the presence of morphologically distinct serratus anterior subdivisions. The results of this study will inform the development of optimal techniques for the assessment, treatment and rehabilitation of this architecturally complex muscle in shoulder and neck pain.

    Computers are an integral part of modern radiology practice. They are used in different radiology modalities to acquire, process, and postprocess imaging data. They have had a dramatic influence on contemporary radiology practice. Their impact has extended further with the emergence of Digital Imaging and Communications in Medicine (DICOM), Picture Archiving and Communication System (PACS), Radiology information system (RIS) technology, and Teleradiology. A basic overview of computer hardware relevant to radiology practice is presented here. The key hardware components in a computer are the motherboard, central processor unit (CPU), the chipset, the random access memory (RAM), the memory modules, bus, storage drives, and ports. The personnel computer (PC) has a rectangular case that contains important components called hardware, many of which are integrated circuits (ICs). The fiberglass motherboard is the main printed circuit board and has a variety of important hardware mounted on it, which are connected by electrical pathways called “buses”. The CPU is the largest IC on the motherboard and contains millions of transistors. Its principal function is to execute “programs”. A Pentium ® 4 CPU has transistors that execute a billion instructions per second. The chipset is completely different from the CPU in design and function; it controls data and interaction of buses between the motherboard and the CPU.

Reference was made to the newest evaluation test, the objective structured clinical examination, which is one of the most complete methodologies at present, although it is made clear that the evaluation is carried out under a created and simulated situation. It is concluded that the bases for making the evaluative tools that will measure the competence or incompetence of our medical sciences professionals should be structured.

  18. Society. Part II: moderate to severe psoriasis

    Full Text Available Psoriasis is a chronic inflammatory skin disease affecting about 1–3% of the general population. Recent years have seen great development in the treatment of this dermatosis, especially regarding moderate to severe psoriasis. More numerous and more widely available systemic therapies raise new challenges for all physicians treating patients with psoriasis. New questions arise about patients’ follow-up and long-term safety of such therapies. To meet the expectations of Polish dermatologists, we have prepared a second part of guidelines on the treatment of psoriasis, particularly concentrated on the therapy of severe forms of this disease. We hope that our suggestions will be valuable for physicians in their daily clinical practice. However, we would like to underline that every guideline is characterized by some vagueness, and the final decision about diagnosis and therapy should always be made individually for every patient based on the patient’s current clinical status and the most up-to-date scientific literature data.

    Two small break loss-of-coolant accident (LOCA) transients are compared to illustrate a scaling methodology for reduced pressure integral facilities. Mapping test 3004 is conducted in the Multiloop Integral System Test (MIST) full pressure, full height facility. The counter-part test MISO3l7 is scaled and performed in the reduced height, reduced pressure UMCP facility. Inventory is used as the chronological scale and pressure, normalized with the initial and system saturation pressures, is used as characteristic parameter to describe the system behavior. The appropriately normalized results conclusively demonstrate that: (a) the same phenomena are observed in the two facilities; (b) the sequence of events is analogous and (c) the trends described by the normalized pressure versus inventory traces are in good quantitative agreement. Each energy transport mode traversed by the two facilities is compared and the phenomena present are described in detail. The differences between the high and reduced pressure tests are outlined. The findings clearly indicate that pressure and height can be scaled for transient where limited boundary conditions are applied and where the break is subcooled. A statement on sensitivity to the initial conditions is also included to define the limitations of the quantitative results

    Bisphenol A (BPA) is a man-made compound, mainly used as a monomer to produce polycarbonate (PC), epoxy resins, non-polymer additives to other plastics, which have many food related applications, such as food storage containers, tableware and internal coating of cans, as well as non-food applications such as electronic equipment, construction materials and medical devices. BPA exposure can occur when the residual monomer migrates into packaged food and beverages. Moreover, due to the ubiquitous presence of this compound, the general population can be exposed to environmental sources such as water, air and soil. Many studies have investigated the potential health hazards associated with BPA, which can elicit toxic and cancerogenic effects on humans. According to the European Food Safety Authority opinion, diet is considered to be the main source of exposure, especially canned food; moreover, among non-canned food, meat and fish products have the highest levels of BPA contamination. This review focuses on BPA contamination in seafood, analysing worldwide literature (from January 2010 to October 2015) on BPA contamination of edible parts. The authors try to identify differences between canned and non-canned seafood in literature, and gaps in the state of art. The data evaluated underline that all concentrations for both canned and non-canned seafood were below the specific migration limit set by the European Community Directive for BPA in food. Moreover, the canned seafood is more contaminated than the non-canned one.

    Caterinicchio, R P

    1987-01-01

    This article is the first of a two-part series which argues for the concurrent management of the appropriateness, necessity, and quality of patient care. Intensifying scrutiny by the credentialing groups, the PROs and all third-party payors underscores the vital need to implement cost-effective information systems which integrate the departmentalized functions of patient-physician profiling, DRG case-mix analyses, length of stay monitoring, pre-admission/admission and continued stay review, discharge planning, risk management, incident reporting and quality review. In the domain of physician performance regarding admitting and practice patterns, the ability to exercise concurrent utilization-quality review means early detection and prevention of events which would otherwise result in denials of payment and/or compromised patient care. Concurrent utilization-quality review must, by definition, be managerially invasive and focused; hence, it is integral to maintaining the integrity of the services and product lines offered by the provider. In fact, if PPO status is a marketing agenda, then the institutional objectives of cost-effectiveness, productivity, value, and competitiveness can only be achieved through concurrent utilization-quality review.

    Full Text Available Pleomorphic hyalinizing angiectatic tumor (PHAT of soft parts is a rare, nonmetastasizing tumor of uncertain lineage which was first reported in 1996. Here, we report a case of PHAT and review the literature. A 49-year-old man presented with a soft and progressively enlarging mass over the right buttock for several years. On suspicion that the mass was a right gluteal lipoma, he underwent surgical excision. The excised lesion measured 14 × 6 × 3.5 cm. It had a variegated appearance with a white-tan to yellowish color on the cut surface. Some punctate hemorrhage and vessel thrombosis were seen. Microscopically, the tumor was a PHAT characterized by clusters of ectatic, fibrin-lined, thin-walled vessels, which were surrounded by a mitotically inert, spindled, pleomorphic, neoplastic stroma that contained a variable inflammatory component. Immunohistochemical study showed that the tumor cells were positive for CD34, and negative for S-100, HMB45 and actin. The patient experienced local recurrence 6 months later. The recurrent tumor was widely excised. No evidence of metastasis was found during the 18 months after the second operation. The recurrent lesion had a microscopic appearance that was similar to the initial lesion.

    Full Text Available The relief of suffering, which is associated with a rapid and complete elimination of painful sensations, is the most important challenge facing physicians of many specialties. It is obvious that it can be solved only when you understand clearly the processes governing the development and chronization of pain. Inflammation, a universal adaptive mechanism that always accompanies damage to living tissues, plays a key role. Part 1 of this review considers the main stages of development of an inflammatory response, beginning with primary damage accompanied by the release of molecules acting as an alarm and ending with the deployment of a complete picture of the inflammatory response with the involvement of many cell elements and the overexpression of cytokines and proinflammatory mediators. The biological basis of the peripheral and central nociceptive sensitization phenomenon that is rigidly associated with inflammation is presented. Particular emphasis is placed on the possible natural completion of the inflammatory response, on the adaptive mechanisms regulating this process and on the reasons that prevent this and determines inflammation chronization.

    From 8.30 to 9.30 p.m. on Saturday, 26 March 2011, the Globe of Science and Innovation will be plunged into darkness to mark CERN's participation in Earth Hour. A growing number of countries and cities across the planet are involved in this global initiative against climate change, which was launched by the WWF in 2007.   The lights on the Globe were switched off for the 2009 Earth Hour event. Along with individuals, companies and tourist attractions in thousands of towns and cities all over the world participating in the fourth annual Earth Hour event, CERN will turn off the lights of the Globe for 60 minutes at 8.30 p.m. on Saturday 26 March. CERN's participation in the initiative is one of several examples of its commitment to respect the environment and keep its ecological footprint to the minimum. A recent example under the green transport heading was the replacement of part of CERN's petrol vehicle fleet with cars running on natural gas with a view to reducing air pollution.

    Full Text Available Three-dimensional (3D textile structures with better delamination resistance and damage impact tolerance to be applied in composites for structural components is one of the main goals of the aeronautical industry. Textile Research Centre in Canet de Mar has been working since 2008 in this field. Our staff has been designing, developing and producing different textile structures using different production methods and machinery to improve three-dimensional textile structures as fiber reinforcement for composites. This paper describes different tests done in our textile labs from unidirectional structures to woven, knitted or braided 3 D textile structures. Advantages and disadvantages of each textile structure are summarized. The second part of this paper deals with our know-how in the manufacturing and assessing of three-dimensional textile structures during this last five years in the field of textile structures for composites but also in the development of structures for other applications. In the field of composites for aeronautic sector we have developed textile structures using the main methods of textile production, that is to say, weaving, warp knitting, weft knitting and braiding. Comparing the advantages and disadvantages it could be said that braided fabrics, with a structure in the three space axes are the most suitable for fittings and frames.

  7. Lipids: Part of the tangled web

    1992-08-01

    Analysis of LDL subclasses by non-denaturing gradient gel electrophoresis has led to the identification of a subclass pattern characterized by predominance of small LDL, designated LDL subclass pattern B. The prevalence of pattern B in the general population is approximately 25%, but varies as a function of age and gender, being relatively uncommon in children and in premenopausal women. The remainder of the population has a predominance of larger LDL (pattern A) or an intermediate pattern. Our findings indicate that LDL subclass pattern B is an integral part of the tangled web'' of interrelated coronary disease risk factors associated with insulin resistance. It may be that the pathologic features of this lipoprotein profile, including the relative atherogenicity of small, dense LDL and IDL, contribute importantly to the increased risk of cardiovascular disease in subjects with insulin resistance and hypertension. Furthermore, pattern B serves as a marker for a common genetic trait which may underlie a substantial portion of the familial predisposition to coronary artery disease in the general population. Studies of hormonal, dietary, and pharmacologic influences on expression of this atherogenic phenotype should lead to more effective identification and management of high-risk individuals, and improved approaches to disease prevention in high-risk families.

    Scott, D. H.

    1972-01-01

    Apollo 16 metric photographs taken at low to high sun angles provided the first stereographic coverage of the distinctive landforms collectively referred to as Imbrium sculpture. The sculpture consists of a series of nearly linear ridges and troughs extending radially outward for more than 1000 km from the rim of the Imbrium Basin. The origin of the ridges and troughs, whether by deposition and impact scoring by fluidized clouds of ejecta from the Imbrium Basin or by faulting and volcanism during and subsequent to basin formation, is controversial. Evidence indicative of the mode of origin of Imbrium sculpture is summarized as follows. Evidence of volcano-tectonic mode of origin is favored by: (1) wide variation in relative age of parts of the sculpture; (2) furrows without rims; (3) absence of ballistic shielding; (4) asymmetry of sculpture; (5) absence of randomly oriented clusters; and (6) association with other features of structural origin. An origin by ejecta scoring and deposition is favored by the gradational ejecta with a Fra Mauro-type texture. Features that are ambiguous as to mode or origin are furrows made of coalesced crater chains and prominent rims on furrows.

    Probability density functions (PDFs) have been derived for a number of commonly used limit of detection definitions, including several variants of the Relative Standard Deviation of the Background-Background Equivalent Concentration (RSDB-BEC) method, for a simple linear chemical measurement system (CMS) having homoscedastic, Gaussian measurement noise and using ordinary least squares (OLS) processing. All of these detection limit definitions serve as both decision and detection limits, thereby implicitly resulting in 50% rates of Type 2 errors. It has been demonstrated that these are closely related to Currie decision limits, if the coverage factor, k, is properly defined, and that all of the PDFs are scaled reciprocals of noncentral t variates. All of the detection limits have well-defined upper and lower limits, thereby resulting in finite moments and confidence limits, and the problem of estimating the noncentrality parameter has been addressed. As in Parts 1-3, extensive Monte Carlo simulations were performed and all the simulation results were found to be in excellent agreement with the derived theoretical expressions. Specific recommendations for harmonization of detection limit methodology have also been made

    Full Text Available Nessa primeira parte do trabalho referente ao estudo dos Procamallanus brasileiros, os autores propoêm que Spirocamallanus Olsen, 1952, seja aceito apenas como um bom subgênero, baseando-se exclusivamente no aspecto de cápsula bucal. Assi, Spirocamallanus identifica os camalanídeos de cápsula bucal com lâminas espiraladas ou outras estruturas semelhantes, enquanto que Procamallanus se aplicaria aos de cápsula bucal lisa. Quanto às demais subdivisões existentes para o gênero, apoiadas em aspecto e quantidade de espículos, são consideradas resultado de um critério bastante arbitrário para conservarem-se válidas, visto serem os espículos caracteres sujeitos a diversas interpretações por parte dos especialistas, devido à fragilidade que os toma tão sujeitos a modificações no grupo dos camalanídeos. Três espécies são aqui tratadas: Procamallanus (Spirocamallanus rarus Travassos, Artigas & Pereira, 1928, Procamallanus (Spirocamallanus pimelodus, e Procamallanus (Spirocamallanus intermedius. As duas últimas são propostas como novas. Procamallanus (S. pimelodus é comparada a Procamallanus (Spirocamallanus olseni Campana-Rouget & Razahihelissoa, 1965, dela se distinguindo, principalmente, por apresentar o rebordo da asa caudal franjado e fortemente musculoso. Procamallanus (S. intermedius aproxima-se unicamente de Procamallanus (S. rarus, por apresentar o espículo maior com bifurcação distal e dela se afasta pelo maior número e menor espessura das lâminas espiraladas na cápsula bucal. Para Procamallanus (S. rarus é apresentada a descrição da fêmea, a redescrição do macho, salientando-se pela primeira vez no gênero, o aspecto singular do espículo maior, aspecto esse também observado ao se lidar com Procamallanus (S. intermedius, depois de se ter tido acesso ao exemplar tipo e único de Procamallanus (S. rarus.

    To (1) demonstrate the needs and benefits of three-dimensional diagnostic and treatment applications; (2) illustrate practical clinical applications of anteroposterior images and frontal analysis; and (3) enhance utilization of the Ricketts and Grummons frontal analyses. Frontal analysis methods and applications are specified and integrated into facial, smile, jaw, and occlusal therapies. Asymmetry conditions must be differentially diagnosed and effectively treated. Frontal and related image analysis and tracing steps are detailed. Asymmetry of facial parts is the rule, rather than the exception. Dental and facial midlines, occlusal plane, chin location, and smile esthetics are primarily emphasized. Beautiful facial proportions and smile harmony can be developed despite initial facial dysmorphosis and disproportions. Patients view themselves from the frontal perspective, so this carries priority when assessing problems. It is important to know the etiology of asymmetry to assist others with genetic counseling. Facial harmony and smile beauty are optimal when facial and maxillary dental midlines are aligned. The maxillary dentition width should be sufficiently wide to be in harmony with the individual patient facial morphology. The occlusal plane should be level and the chin centered as much as possible. Best facial development and proportionality exist when the skeletal and dental components are optimized transversely and are symmetric.

    1994-01-01

    Plasma facing parts of the present invention are constituted by joining an armour comprising a material having a high melting point and a cooling member comprising copper or the like. A metal member having good solderability with the cooling member is disposed on the joined surface of the armor member. In addition, the joined surface of the cooling member is provided with a barrier layer for preventing invasion of a solder. A solder having a low melting point is interposed between the armour and the cooling member. If they are heated entirely, the solder having low melting point is melted, so that the metal member having good solderability disposed on the armor member is soldered with the barrier layer for the cooling member. Upon exchange of the armour, the joint is heated again. Then, the solder having a low melting point is melted and the armour member and the cooling member are separated. If a solder is put on the cooling member and a new armour is placed and then heated, repairing is completed. (I.S.)

    Science.gov (United States)

    Wiechmann, D

    1999-01-01

    One essential component of a successful lingual treatment concept is the precise calculation and manufacture of individual lingual arch wires. As in several parts of daily life, the use of modern CAD/CAM technology leads in lingual orthodontic treatment to a rationalisation of working processes with maximized precision. The lingual module developed by the author is a new scanner-independent procedure for calculation and manufacture of individual lingual arch wires with the Orthomate/Orthotherm system (OrthoTel, Berlin/Dallas, Tx). Especially the precise individualization of superelastic, shape-memory materials reduces the archwire sequence and simplifies lingual treatment considerably. Individual second and third order overcorrections (incisal torque, reverse curve of Spee) can be programmed into the first archwire, with further three-dimensional corrections being added for each single tooth during finishing. Embedded in a systematic treatment concept, the use of modern CAD/CAM technology for individual lingual archwire production with the Orthomate/Orthotherm system is an important aid to successful integration of lingual orthodontic treatment into routine practice.

    2012-03-01

    Cognitive science has become the most influential paradigm on mental health in the late 20(th) and the early 21(st) centuries. In few years, the concepts, problem approaches and solutions proper to this science have significantly changed. Introduction and discussion of the fundamental concepts of cognitive science divided in four stages: Start, Classic Cognitivism, Connectionism, and Embodying / Enacting. The 2(nd) Part of the paper discusses the above mentioned fourth stage and explores the clinical setting, especially in terms of cognitive psychotherapy. The embodying/enacting stage highlights the role of the body including a set of determined evolutionary movements which provide a way of thinking and exploring the world. The performance of cognitive tasks is considered as a process that uses environmental resources that enhances mental skills and deploys them beyond the domestic sphere of the brain. On the other hand, body and mind are embedded in the world, thus giving rise to cognition when interacting, a process known as enacting. There is a close connection between perception and action, hence the interest in real-time interactions with the world rather than abstract reasoning. Regarding clinics, specifically the cognitive therapy, there is little conceptual discussion maybe due to good results from practice that may led us to consider that theoretical foundations are firm and not problem-raising.

    The purpose of the Radiological Assistance Program (RAP) is to make DOE resources available and provide emergency assistance to state and local agencies in order to control radiological hazards, protect the public health and safety, and minimize the loss of property. This plan is an integral part of a nationwide program of radiological assistance established by the US DOE, and is implemented on a regional basis. The Brookhaven Area Office (BHO) Radiological Assistance Program is applicable to DOE Region I, which consists of the New England States, New York, New Jersey, Pennsylvania, Delaware, Maryland and the District of Columbia. The BHO RAP-1 has been developed to: (a) ensure the availability of an effective radiological assistance capability to ensure the protection of persons and property; (b) provide guidelines to RAP-1 Team personnel for the evaluation of radiological incidents and implementation of corrective actions; (c) maintain liaison with other DOE installations, Federal, State and local organizations which may become involved in radiological assistance operations in Region I; and (d) encourage development of a local capability to cope with radiological incidents

  19. Glucocorticoids and fetal programming part 2: Mechanisms.

    Science.gov (United States)

    Moisiadis, Vasilis G; Matthews, Stephen G

    2014-07-01

    The lifelong health of an individual is shaped during critical periods of development. The fetus is particularly susceptible to internal and external stimuli, many of which can alter developmental trajectories and subsequent susceptibility to disease. Glucocorticoids are critical in normal development of the fetus, as they are involved in the growth and maturation of many organ systems. The surge in fetal glucocorticoid levels that occurs in most mammalian species over the last few days of pregnancy is an important developmental switch leading to fundamental changes in gene regulation in many organs, including the brain. These changes are important for the transition to postnatal life. Exposure of the fetus to increased levels of glucocorticoids, resulting from maternal stress or treatment with synthetic glucocorticoids, can lead to long-term 'programming' of hypothalamic-pituitary-adrenal function and behaviours. Glucocorticoids act at multiple levels within the fetal brain. Growing evidence indicates that they can exert powerful effects on the epigenome, including on DNA methylation, histone acetylation and microRNA, to influence gene expression. Such influences probably represent a critical component of the 'programming' process, and might be partly responsible for the transgenerational effects of antenatal glucocorticoid exposure on neurologic, cardiovascular and metabolic function.

    1986-01-01

    The development of reuable software parts has been an area of intense discussion within the software community for many years. An approach is described for developing reusable parts for the applications of missile guidance, navigation and control which meet the following criteria: (1) Reusable; (2) Tailorable; (3) Efficient; (4) Simple to use; and (5) Protected against misuse. Validating the feasibility of developing reusable parts which possess these characteristics is the basis of the Common Ada Missile Packages Program (CAMP). Under CAMP, over 200 reusable software parts were developed, including part for navigation, Kalman filter, signal processing and autopilot. Six different methods are presented for designing reusable software parts.

  2. CRISM's Global Mapping of Mars, Part 1

    Science.gov (United States)

    2007-01-01

    After a year in Mars orbit, CRISM has taken enough images to allow the team to release the first parts of a global spectral map of Mars to the Planetary Data System (PDS), NASA's digital library of planetary data. CRISM's global mapping is called the 'multispectral survey.' The team uses the word 'survey' because a reason for gathering this data set is to search for new sites for targeted observations, high-resolution views of the surface at 18 meters per pixel in 544 colors. Another reason for the multispectral survey is to provide contextual information. Targeted observations have such a large data volume (about 200 megabytes apiece) that only about 1% of Mars can be imaged at CRISM's highest resolution. The multispectral survey is a lower data volume type of observation that fills in the gaps between targeted observations, allowing scientists to better understand their geologic context. The global map is built from tens of thousands of image strips each about 10 kilometers (6.2 miles) wide and thousands of kilometers long. During the multispectral survey, CRISM returns data from only 72 carefully selected wavelengths that cover absorptions indicative of the mineral groups that CRISM is looking for on Mars. Data volume is further decreased by binning image pixels inside the instrument to a scale of about 200 meters (660 feet) per pixel. The total reduction in data volume per square kilometer is a factor of 700, making the multispectral survey manageable to acquire and transmit to Earth. Once on the ground, the strips of data are mosaicked into maps. The multispectral survey is too large to show the whole planet in a single map, so the map is divided into 1,964 'tiles,' each about 300 kilometers (186 miles) across. There are three versions of each tile, processed to progressively greater levels to strip away the obscuring effects of the dusty atmosphere and to highlight mineral variations in surface materials.

    2007-01-01

    After a year in Mars orbit, CRISM has taken enough images to allow the team to release the first parts of a global spectral map of Mars to the Planetary Data System (PDS), NASA's digital library of planetary data. CRISM's global mapping is called the 'multispectral survey.' The team uses the word 'survey' because a reason for gathering this data set is to search for new sites for targeted observations, high-resolution views of the surface at 18 meters per pixel in 544 colors. Another reason for the multispectral survey is to provide contextual information. Targeted observations have such a large data volume (about 200 megabytes apiece) that only about 1% of Mars can be imaged at CRISM's highest resolution. The multispectral survey is a lower data volume type of observation that fills in the gaps between targeted observations, allowing scientists to better understand their geologic context. The global map is built from tens of thousands of image strips each about 10 kilometers (6.2 miles) wide and thousands of kilometers long. During the multispectral survey, CRISM returns data from only 72 carefully selected wavelengths that cover absorptions indicative of the mineral groups that CRISM is looking for on Mars. Data volume is further decreased by binning image pixels inside the instrument to a scale of about 200 meters (660 feet) per pixel. The total reduction in data volume per square kilometer is a factor of 700, making the multispectral survey manageable to acquire and transmit to Earth. Once on the ground, the strips of data are mosaicked into maps. The multispectral survey is too large to show the whole planet in a single map, so the map is divided into 1,964 'tiles,' each about 300 kilometers (186 miles) across. There are three versions of each tile, processed to progressively greater levels to strip away the obscuring effects of the dusty atmosphere and to highlight mineral variations in surface materials.

    The increasing range of application of ionizing radiation in many different areas requires the needs for further education and training. Unfortunately, some aspects of application of ionizing radiation are not planed and announced for all involved personnel-like in military conflicts, when radiation and radioactivity are used as a new kind of ammunition. In that situation there is no time for formal and planned education. During the NATO strikes on Serbia and Montenegro in 1999. depleted uranium (D.U.) ammunition was used. Before that, it was used in Gulf War in 1991. for the first time. Faced with the health consequences of Gulf War for the soldiers of both sides, which were mainly attributed to D.U., Military Medical Service in the Army of Serbia and Montenegro, prepared educational material for the soldiers who could be employed in the area of the D.U. contamination. Considering the information/knowledge as very important part of radiation protection, booklet was prepared and distributed before the NATO strikes on Serbia and Montenegro. In this paper we present the booklet prepared for the military personnel. In the simplified way the nature of D.U. is explained. Some practical aspects of protection and prevention in D.U. contaminated area-how to avoid and minimize radiological hazard of D.U. in the battlefield, as well as how to avoid long-term hazards of D.U., are presented. It is also explained when to ask for medical care and what kind of examination would be necessary in the case of D.U. contamination. 5AUTHORS.

  7. LEDs: revolution or evolution? Part One

    Energy Technology Data Exchange (ETDEWEB)

    Roush, M.

    2000-11-01

    The historical evolution, the current state of light emitting diodes (LEDs), future implications and the promise of this technology for the lighting industry are explored. Some of the misconceptions relative to that promise are dispelled and some of the less obvious benefits that this technology could deliver in the future are discussed. As far as misconceptions are concerned, it is not true that LEDs will deliver light forever at a fraction of the energy of conventional light sources, or that they come in an infinite variety of colours and cost just pennies. Although LEDs per se may last a long time, the fact is that their true life expectancy is only as long as the wiring and the connection within the system, and they are certainly limited. Energy efficiency is another misconception. The truth is that white LEDs (the best for illumination purposes) are limited to less than 10 lumen per Watt, which is hardly a revolutionary improvement over incandescent light sources. Equally disappointing is the misconception concerning price. In actual fact, LEDs in lighting applications are very new and it would require mass production in the millions before LED lighting packages could become inexpensive. At the same time, LEDs have many advantages that are not commonly known. Compactness, very high level of light utilization, high life expectancy and nearly flat mortality curve are some of these. Operating on direct current lends LED installations to battery and solar applications (as for example solar LED road studs to aid in night driving). The absence of ultraviolet emissions in LEDs is another lesser known, but important feature, especially in applications where material degradation is a major concern (as in stores and museums). In general, all indicators point to a bright future for LEDs as their application progresses from decoration to illumination. This topic will be further explored in Part Two of this article. 4 figs.

  8. Development of aero-engines, part II

    Energy Technology Data Exchange (ETDEWEB)

    Dehn, K.

    1943-01-01

    In the second part of his paper, Mr. Dehn enters into the area of problems in engine construction and design. The main question was, how can more power be coaxed from an engine without increasing its stroke displacement and weight. To begin with, a change in combustion-chamber configuration was made. A hemispheric chamber appeared to be the best design. Into this new design was incorporated a system to swirl the fuel-air mixture for better combustion and more power. Also needed was relocation of the spark plug. Since there was better combustion, valves had to be improved. These were hollowed, filled with sodium and finished with chromium or stellite for more hardness. However, the temperature created by these improvements proved to be a serious problem in engine durability. Heat corrosion destroyed pistons and rings, causing the engine not just to seize-up, but to come apart. This resulted in the loss of aircraft. Finally, a system of cooling the pistons from beneath by an oil spray increased both performance and piston life. Dehn summarizes his paper by comparing two cylinder units from Curtis-Wright radial engines, one old, the other new. He claims that these represented advances in engine technology in all areas he discussed. First, the size had not been increased, but the newer one developed more power. This had been accomplished, he reports, by fuel development reducing pre-detonation. The super-charging, and most important, the re-design of the cooling fins on the cylinder head exterior, provided greater thermal capacity for the engine. In this way, power had been increased more than 100 percent. The author concludes his paper by stating that this type of development is possible only through advances in, and use of, materials technology. That would involve intensive co-operation between the scientists and engineers working in fuels development and aviation engineering.

    Clinical preception in practice plays a significant role in the education of both Registered Nurses and practical nurses. This study presents the evaluation of an interprofessional research and development project (2009-2103) on clinical preceptorship between two universities of applied sciences, two vocational institutes and four healthcare organisations in western Finland. The research question was as follows: How did the participants evaluate the process and outcomes of developing preceptorship through an action-research approach? The primary target group consisted of professionals within the healthcare sector and nursing teachers at the universities of applied sciences and the vocational institutes. The five units represented in the healthcare organisations functioned as clinical practice placements for both nursing and practical nursing students, with Registered Nurses and practical nurses acting as their preceptors. Each unit developed a unique preceptorship model to answer their specific needs. The models were implemented and tested during one academic year followed by a quantitative (a 4-point scale) and qualitative evaluation of the process. The models are presented in another article, and the evaluation results are presented in this article. The evaluation showed that preceptorship has become an important and accepted part of work, including the practice of starting any preception at a unit with a thorough introduction. The project's emphasis on critical thinking, reflection and focus on ethics were valued by the staff. Pedagogical further education should be arranged on a regular basis to strengthen the knowledge base of the preceptors. Furthermore, enough time for preceptorship should be allocated, as it is a pedagogical duty. The implication of this project is that more cooperation between different stake holders is needed, in order to narrow the gap between theory and praxis. © 2015 Nordic College of Caring Science.

  10. Radioactivity survey data in Japan, part 1

    International Nuclear Information System (INIS)

    1990-03-01

    The publication is aimed at providing radioactivity survey data in environmental and dietery materials in Japan. Part 1 covers environmental materials, consisting of rain and dry fallout, airborne dust, service water, freshwater, soil, sea water, and sea sediments. Samples were collected from 37 sampling locations during the period between July 1988 and July 1989, and were sent to the Japan Chemical Analysis Center for radiochemical analysis. Strontium 90 and cesium 137 in these environmental materials are tabulated. The maximum concentrations of strontium-90 and cesium-137 were as follows: 0.19±0.074 MBq/Km 2 and 0.63±0.041 MBq/Km 2 , respectively, for rain and dry fallout (domestic program); 0.23±0.025 MBq/Km 2 and 0.30±0.031 MBq/Km 2 for rain and dry fallout (WHO program); 0.002±0.0016 mBq/m 3 and 0.002±0.0007 mBq/m 3 for airborne dust; 5.4±0.27 mBq and 0.5±0.13 mBq for service water; 5.3±0.25 mBq and 0.8±0.14 mBq for freshwater; and 0.6±0.11 Bq/Kg and 3.1±0.21 Bq/Kg for dried soil. Yearly changes in the concentrations of both strontium-90 and cesium-137 from 1985 through 1989 are given in figures. (N.K.)

    Martins E Silva, J

    2010-01-01

    The second part embraces exclusively the main characteristics of the medicine in Ancient Mesopotamia, in its main facets: concept of disease, healers and practice. The disease was considered a divine punishment or resultant from a malign influence. Insofar, the medicine began by being preventive, by the use of appropriate amulets or by offerings or sacrifices intending to pacify those malign forces. The treatment of the generality of the diseases privileged the expulsion of those spirits and malign influences from the patient body, purifying it, which was done by the specific intervention of a approximately shipu (clergymanexorcist); not having results, the treatment was continued by the asû (practical healer) that appealed to a group of physical manipulations, limited surgical acts and the administration or application of prescriptions, resultants of the mixture of organic and inorganic substances. In case of failing, the patients (as well as common healthy individuals or rule leaders) could fall back upon a priest diviner (bârû) that, by examination of the organs of an animal especially sacrificed for, would give a final decision about the disease or the future. Besides this more occult facet, nourished in religious faiths and in the magic, the medicine of Ancient Mesopotamia included rational knowledge, certainly as the result of systematic patients observation and semiotic interpretation. From those observations and knowledge referred to the Sumerian period, carefully logged, refined and transmitted to the following generations, it was built a valuable group of texts with the description of symptoms, signs, diagnosis and prognostic of the most common diseases, still identifiable in the present.

  15. The part task of the part-spacing paradigm is not a pure measurement of part-based information of faces.

    Directory of Open Access Journals (Sweden)

    Qi Zhu

    Full Text Available BACKGROUND: Faces are arguably one of the most important object categories encountered by human observers, yet they present one of the most difficult challenges to both the human and artificial visual systems. A variety of experimental paradigms have been developed to study how faces are represented and recognized, among which is the part-spacing paradigm. This paradigm is presumed to characterize the processing of both the featural and configural information of faces, and it has become increasingly popular for testing hypotheses on face specificity and in the diagnosis of face perception in cognitive disorders. METHODOLOGY/PRINCIPAL FINDINGS: In two experiments we questioned the validity of the part task of this paradigm by showing that, in this task, measuring pure information about face parts is confounded by the effect of face configuration on the perception of those parts. First, we eliminated or reduced contributions from face configuration by either rearranging face parts into a non-face configuration or by removing the low spatial frequencies of face images. We found that face parts were no longer sensitive to inversion, suggesting that the previously reported inversion effect observed in the part task was due in fact to the presence of face configuration. Second, self-reported prosopagnosic patients who were selectively impaired in the holistic processing of faces failed to detect part changes when face configurations were presented. When face configurations were scrambled, however, their performance was as good as that of normal controls. CONCLUSIONS/SIGNIFICANCE: In sum, consistent evidence from testing both normal and prosopagnosic subjects suggests the part task of the part-spacing paradigm is not an appropriate task for either measuring how face parts alone are processed or for providing a valid contrast to the spacing task. Therefore, conclusions from previous studies using the part-spacing paradigm may need re-evaluation with

    -threshold nerve propagation. By expanding the range of mathematical operations to include fractional calculus, we can develop new and potentially useful functional relationships for modeling complex biological systems in a direct and rigorous manner. In Part 2 of this review (Crit Rev Biomed Eng 2004; 32(1):105-193), fractional calculus was applied to problems in nerve stimulation, dielectric relaxation, and viscoelastic materials by extending the governing differential equations to include fractional order terms. In this third and final installment, we consider distributed systems that represent shear stress in fluids, heat transfer in uniform one-dimensional media, and subthreshold nerve depolarization. Classic electrochemical analysis and impedance spectroscopy are also reviewed from the perspective of fractional calculus, and selected examples from recent studies in neuroscience, bioelectricity, and tissue biomechanics are analyzed to illustrate the vitality of the field.

    Full Text Available Purpose. The paper focuses on ensuring the rational choice of parameters of the mating surfaces of parts when designing process equipment based on the methods of artificial intelligence. Methodology. The paper considers the geometric model of a ruled developed surface, the conditions of existence of such a surface and provides a generalized algorithm for surface plotting regardless of the type of the working element or the machine-building product. One of the most common technical surfaces are the ruled ones, among which a special position is occupied by developed surfaces (thanks to their differential-parametric properties: surface tangent plane is n contact along the rectilinear generator and does not change its position in space when changing the point of contact; surfaces can be produced by bending sheet metal. These provisions enable a product manufacturer to save significant material and energy means, therefore, the development of geometric models of such surfaces is an important task. Findings. We analyzed the geometrical model of the developed surface which is incident to two guides. Experimental studies have shown the applicationprospectivity of semi-digger moldboards on moldboard plows, particularly on the double-deck ones. Taking into account the operating speed of the plow 2.8 m/s, the plant residues plowing percentage for plow with semi-digger moldboards is 98.9%, and with the digger ones – 96.1%. Originality.

    This innovation is small, lightweight, and consumes very little electricity as it measures the solar energy attenuated by gases and aerosol particles in the atmosphere. A Sun photometer is commonly used on the Earth's surface, as well as on aircraft, to determine the solar energy attenuated by aerosol particles in the atmosphere and their distribution of sizes. This information is used to determine the spatial and temporal distribution of gases and aerosols in the atmosphere, as well as their distribution sizes. The design for this Sun photometer uses a combination of unique optics and a charge coupled device (CCD) array to eliminate moving parts and make the instrument more reliable. It could be selfcalibrating throughout the year. Data products would be down-welling flux, the direct-diffuse flux ratio, column abundance of gas phase constituents, aerosol optical depth at multiple-wavelengths, phase functions, cloud statistics, and an estimate of the representative size of atmospheric particles. These measurements can be used to obtain an estimate of aerosol size distribution, refractive index, and particle shape. Incident light is received at a light-reflecting (inner) surface, which is a truncated paraboloid. Light arriving from a hemispheric field of view (solid angle 2 steradians) enters the reflecting optic at an entrance aperture at, or adjacent to, the focus of the paraboloid, and is captured by the optic. Most of this light is reflected from an inner surface. The light proceeds substantially parallel to the paraboloid axis, and is detected by an array detector located near an exit aperture. Each of the entrance and exit apertures is formed by the intersection of the paraboloid with a plane substantially perpendicular to the paraboloid axis. Incident (non-reflected) light from a source of limited extent (the Sun) illuminates a limited area on the detector array. Both direct and diffuse illumination may be reflected, or not reflected, before being received on

  11. Engineering BioBrick vectors from BioBrick parts

    Full Text Available Abstract Background The underlying goal of synthetic biology is to make the process of engineering biological systems easier. Recent work has focused on defining and developing standard biological parts. The technical standard that has gained the most traction in the synthetic biology community is the BioBrick standard for physical composition of genetic parts. Parts that conform to the BioBrick assembly standard are BioBrick standard biological parts. To date, over 2,000 BioBrick parts have been contributed to, and are available from, the Registry of Standard Biological Parts. Results Here we extended the same advantages of BioBrick standard biological parts to the plasmid-based vectors that are used to provide and propagate BioBrick parts. We developed a process for engineering BioBrick vectors from BioBrick parts. We designed a new set of BioBrick parts that encode many useful vector functions. We combined the new parts to make a BioBrick base vector that facilitates BioBrick vector construction. We demonstrated the utility of the process by constructing seven new BioBrick vectors. We also successfully used the resulting vectors to assemble and propagate other BioBrick standard biological parts. Conclusion We extended the principles of part reuse and standardization to BioBrick vectors. As a result, myriad new BioBrick vectors can be readily produced from all existing and newly designed BioBrick parts. We invite the synthetic biology community to (1 use the process to make and share new BioBrick vectors; (2 expand the current collection of BioBrick vector parts; and (3 characterize and improve the available collection of BioBrick vector parts.

  12. Autoclave Cycle Optimization for High Performance Composite Parts Manufacturing

    OpenAIRE

    Nele, Luigi; Caggiano, Alessandra; Teti, Roberto

    2016-01-01

    In aeronautical production, autoclave curing of composite parts must be performed according to a specified diagram of temperature and pressure vs time. Part-tool assembly thermal inertia and shape have a large influence on the heating and cooling rate, and therefore on the dwell time within the target temperature range. When simultaneously curing diverse composite parts, the total autoclave cycle time is driven by the part-tool assembly with the lower heating and cooling rates. With the aim t...

    The prominence of part-time employment has dramatically increased both in Germany and across Europe. Germany has experienced above- average growth and currently the prevalence of part-time employment there also exceeds the EU average. Evidently, this involves fundamental structural change as part-time employment has increased regardless of economic trends. Although part-time positions often still entail predominantly low-skilled work, the number of mediumskilled or highly qualified employees ...
