    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.

    This work shows the influence of uranium oxide and uranyl fluoride in the reduction of uranium with Ca and Mg. These additions are more harmful when using smaller bombs. The uranyl fluoride has influence in the reduction process; the curves yield-concentration shows two regions depending upon the salt concentration. The behaviour of this addition in these regions can be explained following the different decompositions that can take place during the reduction process. (Author) 9 refs.

    Full Text Available Se presenta un experimento donde se estudia el efecto de contraste sucesivo negativo consumatorio (CSNC en un paradigma de economía cerrada. En estos diseños los animales no están privados de alimento, viven en las cajas de condicionamiento o en sus jaulas-vivienda y son expuestos al tratamiento experimental durante días. Un grupo de ratones recibió en sus jaulas vivienda agua azucarada al 32% las 24 horas durante trece días (fase precambio y al 4% dos días (fase post-cambio, G 32-4. El grupo control recibió siempre la solución al 4% (G 4-4. Como variable dependiente se registró el consumo (en mi diario. Para analizar los resultados se usó Análisis de Variancia (dos grupos independientes con medidas repetidas. Los animales del G 32-4 mostraron un descenso en su consumo cuando se devaluó la sustancia a 4% en comparación con un grupo que siempre recibió 4%. Este efecto se expresó a las 4 horas del cambio del reforzador y se mantuvo al menos hasta 6 horas posteriores al cambio. Este resultado indica que el efecto se presenta aún en presencia del agua y la comida, con animales saciados y en sus jaulas vivienda. Apoya el predominio de las asociaciones entre la representación interna del reforzador y el que se presenta y se minimiza el efecto de asociaciones entre el contexto y el reforzador. Por otra parte estos resultados su- gieren la potencia del fenómeno estudiado y aumenta su validez ecológica.

    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.

Material y métodosEl presente es un estudio de cohorte prospectivo en el que fueron relevados hombres, de profesión policías, durante el año 1997. Luego se ingresaron en la base de datos hospitalaria aquellos que presentaron eventos en los 10 años posteriores. Se empleó la prueba de la t de Student para variables cuantitativas y regresión logística para las cualitativas. ResultadosSe incluyeron 2.379 personas de sexo masculino. La edad promedio fue de 39,5 ± 9,25 años. La prevalencia de factores de riesgo conocidos por las personas fue: HTA 11,1%, dislipidemia 20,3%, diabetes 2,4%, tabaquismo 43,3%. Noventa pacientes presentaron algún tipo de MACE. El odds ratio para diabetes fue 4,54 (IC 95% 2,1-9,81, HTA 2,3 (IC 95% 1,38-3,85, dislipidemia 2,74 (IC 95% 1,77-4,25 y para tabaquismo 1,48 (IC 95% 0,97-2,28. La edad, el LDL, el fibrinógeno y las horas trabajo diarias mostraron asociaciones significativas. El área bajo la curva ROC del puntaje de Framingham fue de 0,72 y para el puntaje europeo fue de 0,71. ConclusiónLos factores de riesgo de enfermedad cardiovascular clásicos tuvieron una importancia similar a los ya comunicados por los estudios epidemiológicos; es importante destacar algunos no clásicos como el fibrinógeno.

Materiales y Métodos: Se evaluaron 13 bombas de infusión enteral del tipo peristáltico mediante la aplicación de un modelo de laboratorio que simulaba la administración a un paciente. Se usó para todos los casos una fórmula estándar diluida de la manera recomendada por el fabricante. Con un volumen meta de 240 mL. Se programó en cada bomba un flujo de infusión de 40 mL por hora. Para cada caso según el tiempo de infusión, se calculó el flujo de infusión real y a partir de la diferencia se calculó el porcentaje de error. Resultados: En 12 de las 13 bombas se detectó un error por exceso que fue de 7.5% hasta 52.5%. Solo una bomba, de marca distinta a todas las demás demostró un error de 0 mL/h con respecto a lo programado. Ninguna bomba mostró un déficit en el volumen de infusión. Conclusión: En la mayoría de las bombas evaluadas se detectó un porcentaje de error por exceso que supera lo estipulado por el fabricante.

    We examined the gibberellin (GA) and ethylene regulation of submergence-induced elongation in seedlings of the submergence-tolerant lowland rice (Oryza sativa L.) cvs Senia and Bomba. Elongation was enhanced after germination to facilitate water escape and reach air. We found that submergence-induced elongation depends on GA because it was counteracted by paclobutrazol (an inhibitor of GA biosynthesis), an effect that was negated by GA(3). Moreover, in the cv Senia, submergence increased the content of active GA(1) and its immediate precursors (GA(53), GA(19) and GA(20)) by enhancing expression of several GA biosynthesis genes (OsGA20ox1 and -2, and OsGA3ox2), but not by decreasing expression of several OsGA2ox (GA inactivating genes). Senia seedlings, in contrast to Bomba seedlings, did not elongate in response to ethylene or 1-aminocyclopropane-1-carboxylic-acid (ACC; an ethylene precursor) application, and submergence-induced elongation was not reduced in the presence of 1-methylcyclopropene (1-MCP; an ethylene perception inhibitor). Ethylene emanation was similar in Senia seedlings grown in air and in submerged-grown seedlings following de-submergence, while it increased in Bomba. The expression of ethylene biosynthesis genes (OsACS1, -2 and -3, and OsACO1) was not affected in Senia, but expression of OsACS5 was rapidly enhanced in Bomba upon submergence. Our results support the conclusion that submergence elongation enhancement of lowland rice is due to alteration of GA metabolism leading to an increase in active GA (GA(1)) content. Interestingly, in the cv Senia, in contrast to cv Bomba, this was triggered through an ethylene-independent mechanism.

    Full Text Available Este artículo trata sobre las urbanizaciones cerradas en la Región Metropolitana de Buenos Aires (RMBA. El objetivo es entender el impacto socio-territorial de esos barrios a nivel local, metropolitano y nacional. Después de exponer algunos elementos básicos sobre la historia de esas urbanizaciones y su importante desarrollo reciente en la RMBA, se analiza esta mutación de acuerdo con tres categorías: las formas arquitectónicas y urbanas; las funciones de los espacios y las prácticas sociales que permiten o suscitan; y el tipo de relaciones sociales que se crean en esos lugares. Para cada uno de estos tres aspectos se adoptan sucesivamente dos puntos de vista: por una parte, se contempla la situación dentro del barrio cerrado, y por otra, se estudian los cambios que esos barrios implican para sus alrededores y para el resto de la ciudad. En conclusión, nos acercamos a la idea de que esos emprendimientos traducen una profunda mutación de las representaciones de la ciudad para sus residentes: el éxito de los barrios cerrados significa un cambio importante en la idea que se hace la gente de lo que son y deben ser la ciudad y la vida urbanaThis paper deals with gated communities in the Metropolitan Region of Buenos Aires (RMBA.

    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.

    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.

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

Intermediate penalty kickers (n=12 took a pretreatment test of 32 kicks in a “real-play” situation with intermediate goalkeepers (n=3. We established two groups of kickers who underwent 11 treatment sessions using different strategies and then conducted a posttreatment test. The variables we measured were the number of goals scored, whether the direction of the shot was the same or different from the direction of the goalkeeper’s move (DDG, ball speed and the duration of the kicking movement. The results suggest the goalkeepers demonstrated a greater capacity to identify advance cues when faced with CG (closed strategy group kickers and that OG (open strategy group kickers achieved lower ball speeds when modifying the contact surface of the kick.

    Full Text Available El objetivo de este artículo es aportar a la discusión académica sobre la reconfiguración de fronteras y distancias espaciales en la ciudad de Medellín y sus implicaciones en el orden social de la ciudad, a partir del estudio realizado en el sector de El Poblado. Se acerca, por un lado, al discurso de las personas de clase media alta y alta que allí habitan, para entender la construcción simbólica del espacio urbano y las imágenes de ciudad que se están conformando actualmente desde este sector. Por otro lado, examina el impacto de la publicidad de los proyectos urbanísticos y la idea de "ciudad" implícita que estos manejan, la cual promueve unas relaciones particulares entre los habitantes de esta zona con otros lugares de la ciudad, pues pone en juego los diferentes estilos de vida y las relaciones sociales. Finalmente, busca entender cómo la idea y el desarrollo de El Poblado como una nueva centralidad -o centralidad alterna- y de la unidad cerrada como tipo prevaleciente de vivienda potencian y codifican sentidos de la distinción social que llevan a la segregación espacial de aquellos considerados "otros", externos al entorno.

    Here we describe the unusual genesis of steptoes in Las Bombas volcano- Llancanelo Volcanic Field (LVF) (Pliocene - Quaternary), Mendoza, Argentina. Typically, a steptoe forms when a lava flow envelops a hill, creating a well-defined stratigraphic relationship between the older hill and the younger lava flow. In the Llancanelo Volcanic Field, we find steptoes formed with an apparent normal stratigraphic relationship but an inverse age-relationship. Eroded remnants of scoria cones occur in "circular depressions" in the lava field. To express the inverse age-relationship between flow fields and depression-filled cones here we define this landforms as inverse steptoes. Magnetometric analysis supports this inverse age relationship, indicating reverse dipolar magnetic anomalies in the lava field and normal dipolar magnetization in the scoria cones (e.g. La Bombas). Negative Bouguer anomalies calculated for Las Bombas further support the interpretation that the scoria cones formed by secondary fracturing on already solidified basaltic lava flows. Advanced erosion and mass movements in the inner edge of the depressions created a perfectly excavated circular depression enhancing the "crater-like" architecture of the preserved landforms. Given the unusual genesis of the steptoes in LVF, we prefer the term inverse steptoe for these landforms. The term steptoe is a geomorphological name that has genetic implications, indicating an older hill and a younger lava flow. Here the relationship is reversed.

    Full Text Available Este trabajo tiene por objetivo desarrollar un estudio hidromecánico integrador, orientado al diseño de bombas de pistones axiales de máquinas pulverizadoras para la agricultura, basado no solo en estudios anteriores sino en la experiencia acumulada durante los años de trabajo en este tema, dado que la información existente está dirigida fundamentalmente a la selección y explotación de este componente, no sucediendo así para el diseño, y esto dificulta en gran medida el desarrollo de estos equipos en países como Cuba que no cuentan con una tradición y experiencia en este campo, lo que demuestra la importancia del tema para el desarrollo de estos equipos en el país. Para ello se propone una metodología de cálculo específicamente orientada al diseño de estos equipos, y además se realiza un estudio estadístico basado en los datos recopilados de más de cien bombas de producción extranjera de diecinueve firmas de reconocido prestigio internacional que permiten analizar aspectos como: velocidad máxima real de desplazamiento del pistón, caudal y presión de trabajo para estas bombas, respondiendo a las nuevas tendencias internacionales. El aporte teórico de la investigación radica en que este estudio constituye una guía metodológica integradora para el diseño de este tipo de bombas y como aporte práctico la fabricación de estas bombas con la consiguiente sustitución de importaciones y la puesta en marcha del parque de máquinas pulverizadoras, fundamentalmente de producción nacional, que en la actualidad requieren de este componente.

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

    Full Text Available El presente artículo describe el trabajo realizado en el desarrollo de un sistema de bombeo para desalinización con membranas de osmosis inversa. 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.

    2000-07-01

    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. [Spanish] Se ha desarrollado un nuevo programa computacional para el diseno de bombas de calor por compresion de vapor de una sola etapa.

    2010-01-01

    Full Text Available La inyección de fertilizantes en el fertirriego se realiza comúnmente a través de tubos Venturi y se controla con ayuda de sensores de conductividad y pH colocados en la salida del riego. Los tubos Venturi presentan problemas de caídas de presión durante la inyección. De este modo se innova con el diseño de un equipo de fertirriego controlando las perdidas de presión usando un sistema de inyección de fertilizantes por bombas de paletas rotatorias que suministran un caudal continuo. El control de la inyección lo hace un PLC Millenium II XT- 20 con un programa basado en las relaciones de conductividad eléctrica que existen entre las soluciones madre al ser mezcladas entre si y al diluirlas en agua en pruebas de laboratorio utilizando soluciones concentradas para jitomate saladet. Las relaciones permiten predecir el comportamiento de la conductividad eléctrica al variar el porcentaje de cada uno de los elementos que la componen. Las ecuaciones indican que debe suministrarse una relación 3:100, 3 de fertilizante por 100 de agua para obtener la conductividad en el rango de 2 a 3 mS/cm, valor donde la planta tiene un mejor aprovechamiento de los nutrientes. Al comparar la caída de presión en la salida de la inyección el sistema Venturi pierde 40 kPa y el equipo con bombas de paletas no presenta pérdidas de presión.

    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.

Después de analizar los modelos de la herramienta y de la interfase de la misma se procedió a llevar a cabo una validación experimental sobre dos bancos didácticos: un equipo de aire acondicionado aire/aire y una bomba de calor aire/agua. Esto ha permitido validar la bondad del modelo tanto para intercambiadores aire/refrigerante como para agua/refrigerante, incrementando así la versatilidad al modelo. Los resultados obtenidos permiten validar de forma satisfactoria la herramienta informática, siendo las desviaciones del modelo respecto a los valores reales inferiores al 20% en el peor caso, lo que permite emplear la herramienta tanto para optimizar el diseño de este tipo de equipos como para validar estrategias de control conducentes a la mejora de la eficienciaA software tool has been developed which permits developing the design (dimensioned and operation (functioning outside the nominal point of mechanical compression heat pumps of the "split" type. After analyzing the tool models and of the tool interface, experimental validation was done using two training benches: an air conditioning unit (air/air and a heat pump (air/water. This has allowed validation of the accuracy of the model for both air/refrigerant and water/refrigerant systems, thus increasing the versatility of the model. The results obtained have allowed a successful validation of the software, with deviations from model to real values of less than 20% in the worse case. This has allowed the use of the tool both for optimization of the design of these types of equipment, and for validating control strategies in order to improve their efficiency.

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.

Montou-se uma bancada, composta por caixas d'água, tubulações, válvulas, medidores de vazão e de pressão, e uma motobomba para a realização dos ensaios. Esses consistiram em aberturas parciais do registro, na saída da bomba, e medições da vazão e da pressão desenvolvida, e da energia consumida. Tais procedimentos foram realizados, primeiro, utilizando água pura, e depois com águas residuárias, em suas concentrações originais e com diversos graus de diluições. Os ensaios mostraram quedas acentuadas de altura manométrica e de rendimento, e aumento da potência demandada com a vazão recalcada de água residuária em comparação ao desempenho da mesma bomba operando com água limpa; a diluição das águas residuárias promoveu melhor desempenho da bomba em relação àquela com concentração original.This work was carried out to evaluate the performance of a centrifugal pump operating with wastewater from coffee process. Under laboratory conditions, it was determined the hydraulic characteristics (manometric height, engine power and efficiency for a centrifugal pump, operating with clear water and coffee process wastewater. The results have show that manometric height and efficiency was smaller and the engine power was higher when the coffee process wastewater was used in comparison with results obtained for clean water. The smaller the concentration of that coffee wastewater produced the better the performance of the pump in comparison with the performance obtained with original concentration of the coffee wastewater.

    A methodology is proposed that should be followed in any thermal electric power plant to determine the load value at which a unit requires a second circulation water pump without affecting the thermal regime and avoiding an excessive auxiliaries consumption in partial loads. In applying this method the power plant would have an energy saving equivalent to the auxiliaries consumption during an hour, when the unit as operating at full load. [Espanol] Se propone una metodologia que debe seguirse en cualquier central termoelectrica para determinar el valor de la carga en la cual una unidad requiere de la segunda bomba de agua de circulacion sin afectar el regimen termico y evitadose un excesivo consumo de auxiliares en cargas parciales.

    Full Text Available RESUMO Objetivo: Analisar as correlações da taxa de fluxo sanguíneo e rotação da bomba com a pressão transmembrana e a transferência de CO2 e O2 durante o suporte respiratório extracorpóreo. Métodos: Cinco animais foram instrumentalizados e submetidos à oxigenação extracorpórea de membrana em um protocolo de cinco fases, as quais incluíam sepse abdominal e lesão pulmonar. Resultados: Este estudo demonstrou que as variações da taxa de fluxo sanguíneo e rotação da bomba dependem, de forma logarítmica positiva, do fluxo sanguíneo na membrana extracorpórea de oxigenação. As variações da taxa de fluxo sanguíneo e rotação da bomba têm associação negativa com a pressão transmembrana (R2 = 0,5 para o fluxo sanguíneo = 1.500mL/minuto e R2 = 0,4 para o fluxo sanguíneo = 3.500mL/minuto, ambos com p 6L/minuto, p = 0,006. A taxa de fluxo sanguíneo com a rotação da bomba não se associa às variações na transferência de O2 (R2 = 0,01 para o fluxo sanguíneo = 1.500mL/minuto, p = 0,19, e R2 = -0,01 ao fluxo sanguíneo = 3.500mL/minuto, p = 0,46. Conclusão: Neste modelo em animais, a variação da taxa de fluxo sanguíneo e rotação da bomba se associa negativamente com a pressão transmembrana e positivamente com a transferência de CO2. Conforme a situação clínica, uma diminuição na taxa do fluxo sanguíneo e rotação da bomba pode, na ausência de hipoxemia, indicar uma disfunção do pulmão artificial.

    Full Text Available No período de abril a dezembro de 1990, quatro pacientes foram submetidos a utilização de bomba centrífuga, para suporte circulatório. Em todos, foi colocado previamente balão intra-aórtico e feito uso maciço de drogas vasoativas. A primeira paciente apresentava aneurisma de ventrículo esquerdo, com fração de ejeção de 16% no pré-operatório. Após correção do aneurisma, não se conseguiu retirá-la de extracorpórea pelos métodos convencionais. Optou-se, então, pelo uso de assistência ventricular esquerda, que foi mantida por 48 horas. Teve boa evolução, estando, atualmente, no 11º mês de pós-operatório em classe funcional II. O segundo caso foi de paciente submetido a revascularização do miocárdio e troca valvar mitral. No 2? dia de pós-operatório, apresentou oclusão de ponte de safena para descendente anterior, com infarto e parada cardíaca. Massageado, reaberto e recolocado em circulação extracorpórea, não saiu de "bomba". O ventrículo esquerdo apresentava infarto anterior extenso, sendo colocado em assistência ventricular esquerd como "ponte" para transplante. Após cinco dias de assistência, sem se conseguir doador, apresentou óbito por embolia pulmonar. O terceiro caso foi de paciente com má função ventricular esquerda, submetido a revascularização do miocárdio. Também não se conseguiu retirar de circulação extracorpórea. Foi colocado em assistência ventricular esquerda por 32 horas, quando se conseguiu retirar a bomba centrífuga. Esse paciente apresentou distúrbios severos de coagulação. Apesar de estável hemodinamicamente, houve piora progressiva da função pulmonar, com óbito no 4º dia de pós-operatório. O quarto caso foi de paciente submetido a correção de aneurisma de ventrículo esquerdo e revascularização do miocárdio. Não se conseguiu retirar de circulação extracorpórea, e optado por assistência ventricular esquerda com bomba centrífuga. Apresentou melhora

    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. With this assembly is unnecessary a pump to the right side: the gradient of transpulmonary pressure was obtained by increasing the pulmonary artery pressure by volemic expansion and decreasing the left atrial pressure by draining this camera by means of a siphon. 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

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.

    Full Text Available O tratamento da síndrome de baixo débito cardíaco tem evoluído muito, em especial em relação aos dispositivos mecânicos de assistência ventricular. Esses dispositivos podem genericamente ser agrupados em pulsáteis e não pulsáteis. Existe grande polêmica sobre as vantagens e desvantagens de cada um desses grupos de dispositivos. O objetivo deste trabalho é avaliar a ação da bomba centrífuga sobre o fluxo coronário e carotídeo na assistência circulatória do ventrículo esquerdo em cães com coração normal. Além disso, verificamos se o uso concomitante do balão intra-aórtico é suficiente para contrabalançar os possíveis efeitos deletérios da assistência circulatória com fluxo contínuo. Foram estudados 15 cães, com peso corpóreo médio de 16,3 kg. Realizamos a avaliação hemodinâmica dos animais, através da medida seriada das pressões do átrio direito, do capilar pulmonar, das artérias pulmonares, da circulação arterial sistêmica e a freqüência cardíaca. Foi realizada a aferição do débito cardíaco e calculados os seguintes parâmetros hemodinâmicos derivados: índice cardíaco, índice sistólico, resistência vascular sistêmica e resistência vascular pulmonar. O fluxo sangüíneo carotídeo e coronariano foram obtidos com o uso de transdutores eletromagnéticos. Os parâmetros foram analisados em quatro situações: S1. situação controle; S2. situação de teste da bomba centrífuga em que esse dispositivo realiza a assistência circulatória do ventrículo esquerdo; S3. situação de teste da bomba centrífuga e do balão intra-aórtico; S4. situação final em que é feita a contraprova desligando-se o balão intra-aórtico. A avaliação hemodinâmica através dos diversos parâmetros não mostrou alteração estatisticamente significante nas quatro situações. Já em relação ao fluxo coronário a utilização da assistência circulatória isolada com bomba centrífuga (S2 e S4 diminuiu

    realizado todavía en Chile. 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)

    We have created the Knowledgebase of Standard Biological Parts (SBPkb) as a publically accessible Semantic Web resource for synthetic biology (sbolstandard.org). The SBPkb allows researchers to query and retrieve standard biological parts for research and use in synthetic biology. Its initial version includes all of the information about parts stored in the Registry of Standard Biological Parts (partsregistry.org). 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.

  19. Standard biological parts knowledgebase.

    Directory of Open Access Journals (Sweden)

    Michal Galdzicki

    Full Text Available We have created the Knowledgebase of Standard Biological Parts (SBPkb as a publically accessible Semantic Web resource for synthetic biology (sbolstandard.org. The SBPkb allows researchers to query and retrieve standard biological parts for research and use in synthetic biology. Its initial version includes all of the information about parts stored in the Registry of Standard Biological Parts (partsregistry.org. 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.

    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.

    We study dimensional properties of visible parts of fractal percolation in the plane. Provided that the dimension of the fractal percolation is at least 1, we show that, conditioned on non-extinction, almost surely all visible parts from lines are 1-dimensional. Furthermore, almost all of them have positive and finite Hausdorff measure. We also verify analogous results for visible parts from points. These results are motivated by an open problem on the dimensions of visible parts.

    Full Text Available La proliferación de countries y barrios cerrados en el conurbano bonaerense ha tenido como correlato una repercusión social notoria, seguida por el interés de las ciencias sociales. 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.

    The Majorana Demonstrator is an ultra-low background physics experiment searching for the neutrinoless double beta decay of $^{76}$Ge. The Majorana Parts Tracking Database is used to record the history of components used in the construction of the Demonstrator. The tracking implementation takes a novel approach based on the schema-free database technology CouchDB. Transportation, storage, and processes undergone by parts such as machining or cleaning are linked to part records. Tracking parts provides a great logistics benefit and an important quality assurance reference during construction. In addition, the location history of parts provides an estimate of their exposure to cosmic radiation. A web application for data entry and a radiation exposure calculator have been developed as tools for achieving the extreme radio-purity required for this rare decay search.

  18. Identification based on facial parts

    Directory of Open Access Journals (Sweden)

    Stevanov Zorica

    2007-01-01

    Full Text Available Two opposing views dominate face identification literature, one suggesting that the face is processed as a whole and another suggesting analysis based on parts. Our research tried to establish which of these two is the dominant strategy and our results fell in the direction of analysis based on parts. The faces were covered with a mask and the participants were uncovering different parts, one at the time, in an attempt to identify a person. Already at the level of a single facial feature, such as mouth or eye and top of the nose, some observers were capable to establish the identity of a familiar face. Identification is exceptionally successful when a small assembly of facial parts is visible, such as eye, eyebrow and the top of the nose. Some facial parts are not very informative on their own but do enhance recognition when given as a part of such an assembly. Novel finding here is importance of the top of the nose for the face identification. Additionally observers have a preference toward the left side of the face. Typically subjects view the elements in the following order: left eye, left eyebrow, right eye, lips, region between the eyes, right eyebrow, region between the eyebrows, left check, right cheek. When observers are not in a position to see eyes, eyebrows or top of the nose, they go for lips first and then region between the eyebrows, region between the eyes, left check, right cheek and finally chin.

    Amram, Meirav; Dagan, Miriam; Ioshpe, Michael; Satianov, Pavel

    2016-10-01

    The staircase and fractional part functions are basic examples of real functions. They can be applied in several parts of mathematics, such as analysis, number theory, formulas for primes, and so on; in computer programming, the floor and ceiling functions are provided by a significant number of programming languages - they have some basic uses in various programming tasks. In this paper, we view the staircase and fractional part functions as a classical example of non-continuous real functions. We introduce some of their basic properties, present some interesting constructions concerning them, and explore some intriguing interpretations of such functions. Throughout the paper, we use these functions in order to explain basic concepts in a first calculus course, such as domain of definition, discontinuity, and oddness of functions. We also explain in detail how, after researching the properties of such functions, one can draw their graph; this is a crucial part in the process of understanding their nature. In the paper, we present some subjects that the first-year student in the exact sciences may not encounter. We try to clarify those subjects and show that such ideas are important in the understanding of non-continuous functions, as a part of studying analysis in general.

    Latombe, J.C. [Stanford Univ., CA (United States). Robotics Lab.; Wilson, R.H. [Sandia National Labs., Albuquerque, NM (United States). Intelligent Systems and Robotics Center

    1995-02-21

    The goal of assembly sequencing is to plan a feasible series of operations to construct a product from its individual parts. Previous research has thoroughly investigated assembly sequencing under the assumption that parts have nominal geometry. This paper considers the case where parts have toleranced geometry. Its main contribution is an efficient procedure that decides if a product admits an assembly sequence with infinite translations that is feasible for all possible instances of the components within the specified tolerances. If the product admits one such sequence, the procedure can also generate it. For the cases where there exists no such assembly sequence, another procedure is proposed which generates assembly sequences that are feasible only for some values of the toleranced dimensions. If this procedure produces no such sequence, then no instance of the product is assemblable. Finally, this paper analyzes the relation between assembly and disassembly sequences in the presence of toleranced parts. This work assumes a simple, but non-trivial tolerance language that falls short of capturing all imperfections of a manufacturing process. Hence, it is only one step toward assembly sequencing with toleranced parts.

    The majority of resources, like time and costs, consumed in industrial product development can be related to detailed design, i.e. the materialisation of machine parts (German Maschinenteile). Existing design theories based on a systems approach, e.g. Haberfellner [5] all have function, i.......e. transformation from input to output or ability to deliver purposeful effects as the core concept. The units in a product which posses functions are the organs (German: Funktionsträgern). Because individual parts do not posses functions, one could argue that the design theories based on a systems approach...... to be identification of a purposeful behaviour concept, i.e. function for a machine part. The contribution is based on the theory of technical systems, Hubka and the domain theory, Andreasen....

  4. Update on rheumatology: part 1.

    Neal-Boylan, Leslie

    2009-05-01

    There are many rheumatic diseases. Part 1 of this 2 part series on rheumatology presented a few of those most commonly seen in the community. Home health clinicians can be helpful in managing these diseases and preventing progression by watching for new symptoms or acute attacks of pain or disability, ensuring that patients take their medications appropriately, reminding patients to see their rheumatology providers and have their lab work done regularly, and reporting adverse effects to medications promptly. Additionally, as with most home health patients, an interdisciplinary approach that includes physical and occupational therapy, social work, nursing, nutrition, and other disciplines as needed should be implemented so that all patient needs are met and the patient is discharged at the highest level of self-care that is possible. Part 2 of this series will discuss the care of the patient with rheumatic disease at home and will provide a more in-depth look at lab diagnosis of rheumatic diseases.

  8. Ultrasonic Assembly of Thermoplastic Parts

    Schurman, W. R.

    1970-03-31

    Four ultrasonic methods were evaluated for assembly of experimental plastic parts for detonators: (1) welding, (2) crimping and staking, (3) insertion, and (4) reactivation of adhesives. For welding, staking and insertion, plastics with low elastic moduli, such as acrylics and polycarbonate, produced the best results. Thermosetting, hot-melt, and solution adhesives could all be activated ultrasonically to form good bonds on plastics and other materials. This evaluation indicated that thermoplastic detonator parts could be assembled ultrasonically in shorter times than by present production techniques with high bond strengths and high product acceptance rates.

  12. Speech parts as Poisson processes.

    Science.gov (United States)

    Badalamenti, A F

    2001-09-01

    This paper presents evidence that six of the seven parts of speech occur in written text as Poisson processes, simple or recurring. The six major parts are nouns, verbs, adjectives, adverbs, prepositions, and conjunctions, with the interjection occurring too infrequently to support a model. The data consist of more than the first 5000 words of works by four major authors coded to label the parts of speech, as well as periods (sentence terminators). Sentence length is measured via the period and found to be normally distributed with no stochastic model identified for its occurrence. The models for all six speech parts but the noun significantly distinguish some pairs of authors and likewise for the joint use of all words types. Any one author is significantly distinguished from any other by at least one word type and sentence length very significantly distinguishes each from all others. The variety of word type use, measured by Shannon entropy, builds to about 90% of its maximum possible value. The rate constants for nouns are close to the fractions of maximum entropy achieved. This finding together with the stochastic models and the relations among them suggest that the noun may be a primitive organizer of written text.

  18. 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.

  20. The Emergence of Axial Parts

    Directory of Open Access Journals (Sweden)

    Peter Svenonius

    2007-01-01

    Full Text Available Many languages have specialized locative words or morphemes translating roughly into words like ‘front,’ ‘back,’ ‘top,’ ‘bottom,’ ‘side,’ and so on. Often, these words are used instead of more specialized adpositions to express spatial meanings corresponding to ‘behind,’ ‘above,’ and so on. I argue, on the basis of a cross-linguistic survey of such expressions, that in many cases they motivate a syntactic category which is distinct from both N and P, which I call AxPart for ‘Axial Part’; I show how the category relates to the words which instantiate it, and how the meaning of the construction is derived from the combination of P[lace] elements, AxParts, and the lexical material which expresses them.

    Part 1 of this paper explored the origins of process activity mapping, one of the major tools currently being used to modernize patient pathways in the National Health Service in Great Britain. Within medical photography the current notion of modernization is inextricably linked to the development of digital technology. Whilst the core principle of capturing light on a sensitive medium remains as clear and relevant as ever, the mechanisms by which the image is processed and presented to the client have changed profoundly. Part 2 shows how the principles of lean thinking and process activity mapping can be utilized to harness the advantages of digital technology to provide a modern and appropriate medical photography service in a large disparate teaching hospital.

    Government, media and public focus on waiting times in the National Health Service in the United Kingdom has forced the organization to look closely at the process by which a patient progresses through an increasingly complex and ever changing system. In an effort to streamline the patient journey or care pathway, modernizers have turned to business and manufacturing for solutions. Whilst medical photographers need to recognize their role in this context, they are also facing major technological modernization through the development of digital photography. Part 1 of this paper looks at the origins of some of the techniques presently being used to modernize the patient journey. Part 2 shows how these tools of modernization can be utilized to harness the advantages of digital technology to provide a modern and appropriate medical photography service in a large, disparate teaching hospital.

  7. Automotive stamped part fatigue design

    Directory of Open Access Journals (Sweden)

    Caudoux Mélanie

    2014-06-01

    Full Text Available Fatigue design of automotive axle parts is of prior concern because of these are high safety parts and they are expected to drive the overall vehicle mass reduction. In this framework, the stamping process is widely used to form axle parts, before assembling them by welding. Consequently, the mechanical and physical characteristics of the blank sheet are modified, having a strong influence on the fatigue behavior. In this paper, we address the consequences of the stamped process on the fatigue design and how they may be effectively taken into account in the automotive industry. Actually, the coupling between the stamping process and the fatigue design is under development at PSA Peugeot Citroën Company since several years. Such an analysis deals with some major topics: thickness variation, plastic hardening and deformation, and residual stress. All of these ingredients result in fatigue criteria evolutions: it is important to stress that the stamping process can have advantageous or disadvantageous consequences on the fatigue design. This is here highlighted on some examples, dealing with front and rear axles.

    A safety case is a collation of the arguments and supporting evidence needed to demonstrate that an item is safe to use. Although there are regulatory and legislative requirements in some industries, and in some parts of the world, for the production of a safety case, there are few standard definitions of what should go into one. Indeed, there is no single, correct, way to prepare a safety case; but this should not be surprising, given the wide variety of applications to which they are put.

    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.

    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 two part Sperner theorem of Katona and Kleitman states that if $X$ is an $n$-element set with partition $X_1 \\cup X_2$, and $\\cF$ is a family of subsets of $X$ such that no two sets $A, B \\in \\cF$ satisfy $A \\subset B$ (or $B \\subset A$) and $A \\cap X_i=B \\cap X_i$ for some $i$, then $|\\cF| \\le {n \\choose \\lfloor n/2 \\rfloor}$. We consider variations of this problem by replacing the Sperner property with the intersection property and considering families that satisfiy various combinations of these properties on one or both parts $X_1$, $X_2$. Along the way, we prove the following new result which may be of independent interest: let $\\cF, \\cG$ be families of subsets of an $n$-element set such that $\\cF$ and $\\cG$ are both intersecting and cross-Sperner, meaning that if $A \\in \\cF$ and $B \\in \\cG$, then $A \

    The previous article in this series of 11, Facilitation of learning: part 1, reviewed learning theories and how they relate to clinical practice. Developing an understanding of these theories is essential for mentors and practice teachers to enable them to deliver evidence-based learning support. This is important given that effective learning support is dependent on an educator who possesses knowledge of their specialist area as well as the relevent tools and methods to support learning. The second domain of the Nursing and Midwifery Council's Standards to Support Learning and Assessment in Practice relates to the facilitation of learning. To fulfil this domain, mentors and practice teachers are required to demonstrate their ability to recognise the needs of learners and provide appropriate support to meet those needs. This article expands on some of the discussions from part 1 of this article and considers these from a practical perspective, in addition to introducing some of the tools that can be used to support learning.

    This updated, PART C REVIEW, covers the dangerous global spread of JS-stealth, drone technology [1-91], canard-free, stealth, new agile drones and the highly debated, 480 billion F-35 International Program as reported on March 13, 2013 to the U.S. Congress [92]. Due to serious design issues, spiraling high costs and years in delays, alternatives are analyzed here, depicted and proposed, mainly from the propulsion-design point of view. These include fleets of low-cost, stealth, jet-steered-drones mixed with non-stealthy, low-cost, ready-to-be-delivered, U.S. or European or Russian fighter aircraft. Can a few F-35s win against large fleets of stealth agile drones? To understand the dangers and critical issues involved, the author's own, past classified information is partly disclosed, while resorting to images in Figs. 2(a) and 2(b) taken from his book [2] and from Wikipedia, the "Free Encyclopedia", in all other images.

    The proper management of your revenue cycle requires the application of "best practices" and the continual monitoring and measuring of the entire cycle. The correct technology will enable you to gain the insight and efficiencies needed in the ever-changing healthcare economy. The revenue cycle is a process that begins when you negotiate payor contracts, set fees, and schedule appointments and continues until claims are paid in full. Every single step in the cycle carries equal importance. Monitoring all phases and a commitment to continually communicating the results will allow you to achieve unparalleled success. In part I of this article, we explored the importance of contracting, scheduling, and case management as well as coding and clinical documentation. We will now take a closer look at the benefits charge capture, claim submission, payment posting, accounts receivable follow-up, and reporting can mean to your practice.

    2013-03-15

    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.

  15. Higher Spin Theory -- Part I

    CERN Document Server

    Rahman, Rakibur

    2013-01-01

    These notes comprise a part of the introductory lectures on Higher Spin Theory presented in the Eighth Modave Summer School in Mathematical Physics. We construct free higher-spin theories and turn on interactions to find that inconsistencies show up in general. Interacting massless fields in flat space are in tension with gauge invariance and this leads to various no-go theorems. While massive fields exhibit superluminal propagation, appropriate non-minimal terms may cure such pathologies as they do in String Theory -- a fact that we demonstrate. Given that any interacting massive higher-spin particle is described by an effective field theory, we compute a model independent upper bound on the ultraviolet cutoff in the case of electromagnetic coupling in flat space and discuss its implications. Finally, we consider various possibilities of evading the no-go theorems for massless fields, among which Vasiliev's higher-spin gauge theory is one. We work out a simple example of a higher-derivative cubic coupling in...

  16. 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.

    Blair, J. Bryan; Scott, V. Stanley, III; Ramos-Izquierdo, Luis

    2008-01-01

    Range-imaging instruments of a type now under development are intended to generate the equivalent of three-dimensional images from measurements of the round-trip times of flight of laser pulses along known directions. These instruments could also provide information on characteristics of targets, including roughnesses and reflectivities of surfaces and optical densities of such semi-solid objects as trees and clouds. Unlike in prior range-imaging instruments based on times of flight along known directions, there would be no moving parts; aiming of the laser beams along the known directions would not be accomplished by mechanical scanning of mirrors, prisms, or other optical components. Instead, aiming would be accomplished by using solid-state devices to switch input and output beams along different fiber-optic paths. Because of the lack of moving parts, these instruments could be extraordinarily reliable, rugged, and long-lasting. An instrument of this type would include an optical transmitter that would send out a laser pulse along a chosen direction to a target. An optical receiver coaligned with the transmitter would measure the temporally varying intensity of laser light reflected from the target to determine the distance and surface characteristics of the target. The transmitter would be a combination of devices for generating precise directional laser illumination. It would include a pulsed laser, the output of which would be coupled into a fiber-optic cable with a fan-out and solid-state optical switches that would enable switching of the laser beam onto one or more optical fibers terminated at known locations in an array on a face at the focal plane of a telescope. The array would be imaged by the telescope onto the target space. The receiver optical system could share the aforementioned telescope with the transmitter or could include a separate telescope aimed in the same direction as that of the transmitting telescope. In either case, light reflected

  19. The genus Allium. Part 2.

    Science.gov (United States)

    Fenwick, G R; Hanley, A B

    1985-01-01

    Allium is a genus of some 500 species belonging to the family Liliaceae. However only a few of these are important as food plants, notably onion, garlic, chive, leek, and rakkyo. Such plants have been used for many centuries for the pungency and flavoring value, for their medicinal properties, and, in some parts of the world, their use also has religious connotations. The flavors of members of the genus Alliums, in addition to having certain characteristics, are also complex, being derived enzymically from a number of involatile precursors. In addition to there being variation of flavor between different alliums, there are also considerable changes that occur as a result of cooking and processing. Of course, these are of importance to the consumer and food technologist-processor. The review will introduce the subject by an historical perspective and will set this against data on the present cultivation and usage of commercially cultivated alliums. The chemical composition of these plants will be discussed, emphasis being given to nonvolatile constituents which are, perhaps, less often considered. Discussion of the volatile constituents, which will include mention of the methods currently used for their analysis and for the determination of "flavor strength", will be mainly concerned with literature taken from the last 5 years. In considering the extent and nature of allium cultivation and processing, factors affecting the nutritional value and quality will be highlighted. The medicinal properties of garlic and onion oils have been much studied over the last decade and the review will include critical assessment of this area and also will touch on the more general properties (antimicrobial, antifungal, antibacterial, and insecticidal) of these oils. Finally mention will be made of the antinutritional, toxic, or otherwise undesirable effects of alliums, for example, as inadvertent components of animal diets, tainting of milk and other food products. It is our

Our software not only takes advantage of modularity, but it also enforces standardisation in part characterisation by considering a model of each part. We have used model parts in SBML to design transcriptional networks. Our software is open source, it works in linux and windows platforms, and it could be used to automatically produce models in a server. Our tool not only facilitates model design, but it will also help to promote the establishment of a registry of model parts.

For that reason, the Set Parts Supply (SPS system was introduced by Toyota as a new material handling system for supplying parts in sets based on the kitting concept. In this study, we investigate the consideration of design concepts in SPS implementation at one of Malaysia’s automotive manufacturers through a case study in a mixed-model assembly line that contains many parts to be assembled to the car body. From our case study, we found that the design of the ‘parts only’ or minomi concept on the component racks contributes to the elimination of waste; mura, muri and muda.

  16. Metrology of Large Parts. Chapter 5

    Science.gov (United States)

    Stahl, H. Philip

    2012-01-01

    As discussed in the first chapter of this book, there are many different methods to measure a part using optical technology. Chapter 2 discussed the use of machine vision to measure macroscopic features such as length and position, which was extended to the use of interferometry as a linear measurement tool in chapter 3, and laser or other trackers to find the relation of key points on large parts in chapter 4. This chapter looks at measuring large parts to optical tolerances in the sub-micron range using interferometry, ranging, and optical tools discussed in the previous chapters. The purpose of this chapter is not to discuss specific metrology tools (such as interferometers or gauges), but to describe a systems engineering approach to testing large parts. Issues such as material warpage and temperature drifts that may be insignificant when measuring a part to micron levels under a microscope, as will be discussed in later chapters, can prove to be very important when making the same measurement over a larger part. In this chapter, we will define a set of guiding principles for successfully overcoming these challenges and illustrate the application of these principles with real world examples. While these examples are drawn from specific large optical testing applications, they inform the problems associated with testing any large part to optical tolerances. Manufacturing today relies on micrometer level part performance. Fields such as energy and transportation are demanding higher tolerances to provide increased efficiencies and fuel savings. By looking at how the optics industry approaches sub-micrometer metrology, one can gain a better understanding of the metrology challenges for any larger part specified to micrometer tolerances. Testing large parts, whether optical components or precision structures, to optical tolerances is just like testing small parts, only harder. Identical with what one does for small parts, a metrologist tests large parts and optics

  1. 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.

    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.

    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.

    2011-01-01

    To facilitate future research in unsupervised induction of syntactic structure and to standardize best-practices, we propose a tagset that consists of twelve universal part-of-speech categories. In addition to the tagset, we develop a mapping from 25 different treebank tagsets to this universal set. As a result, when combined with the original treebank data, this universal tagset and mapping produce a dataset consisting of common parts-of-speech for 22 different languages. We highlight the use of this resource via two experiments, including one that reports competitive accuracies for unsupervised grammar induction without gold standard part-of-speech tags.

    Detailed manufacturing information about the parts can help designers produce better designs. Detailed manufacturing information is conveyed to the designer through micro-circles within the concurrent design process for machined parts, focusing on instantaneous product design and process planning. The process has three key elements: a hierarchical architecture design of the concurrent process planning system, modeling and reengineering of the concurrent process planning, and modeling of information. The approach is successfully implemented and applied for concurrent design and process planning of some complicated parts.

    Full Text Available Background: The soft tissues injury in periarticular fractures of the lower extremities determines the proper time to perform bone fixation. Objetive: The aim of this study was to determine the intra and interobserver agreement in the Tscherne classification. Methods: This is a descriptive, prospective study for patients admitted to the Pablo Tobón Uribe Hospital (PTUH with tibial plateau or tibial pilon fractures. We performed a standardize evaluation using video photography at the time of admission and 24, 48, and 72 h after admission. Fifteen five reviewers who had various levels of training produced a total of 1,200 observations. The intra- and interobserver agreement was assessed using a weighted kappa for multiple raters and more than two categories. Results: Twenty patients were admitted with tibial plateau and tibial pilon fractures. The intraobserver agreement for all 15 raters was kappa 0.81 (95% CI 0.79-0.83, and the interobserver agreement for all 15 raters was kappa 0.65 (95% CI 0.55-0.73. The interobserver agreement at 24 h was kappa 0.67 (95% CI 0.46-0.86. Conclusions:Classifying the severity of soft tissue injury is critical in planning the surgical management of fractures of the lower extremities. Based on our results, we can reasonably argue that the Tscherne classification produced an adequate level of agreement and could be used to standardize and to guide the treatment, and to conduct research studies.Level of Evidence: Level IV, Case Series

  14. 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.

  3. DISCRETIZATION APPROACH USING RAY-TESTING MODEL IN PARTING LINE AND PARTING SURFACE GENERATION

    Institute of Scientific and Technical Information of China (English)

    HAN Jianwen; JIAN Bin; YAN Guangrong; LEI Yi

    2007-01-01

    Surface classification, 3D parting line, parting surface generation and demoldability analysis which is helpful to select optimal parting direction and optimal parting line are involved in automatic cavity design based on the ray-testing model. A new ray-testing approach is presented to classify the part surfaces to core/cavity surfaces and undercut surfaces by automatic identifying the visibility of surfaces. A simple, direct and efficient algorithm to identify surface visibility is developed. The algorithm is robust and adapted to rather complicated geometry, so it is valuable in computer-aided mold design systems. To validate the efficiency of the approach, an experimental program is implemented. Case studies show that the approach is practical and valuable in automatic parting line and parting surface generation.

  4. Living musical instruments and inanimate body parts?

    Barbarotto, R; Capitani, E; Laiacona, M

    2001-01-01

    In the literature about category effects in semantic memory, body parts and musical instruments are often considered atypical, because in cases with a disproportionate impairment of living categories body parts are relatively spared, while musical instruments are often severely defective. In this study the performance of 57 subjects affected by diseases generally associated with lexical-semantic impairment, for the most part Alzheimer's disease and other forms of cortical degeneration, but also herpetic encephalitis and traumatic brain damage are analyzed. The subjects were given a picture naming task tapping eight categories: three living categories (animals, fruits and vegetables) and three non-living categories (tools, furniture and vehicles), plus body parts and musical instruments. On a preliminary analysis at the group level, body parts were the least impaired category and musical instruments the most severely impaired, the six living and non-living categories being intermediate. However, these differences disappeared after covariance for lexical frequency, name agreement and age of acquisition. The relationship between living categories, non-living categories, musical instruments and body parts was investigated by means of a Lisrel model of Confirmatory Factor Analysis. Two latent variables related to living and non-living categories respectively were defined, and it was found that both body parts and musical instruments were significantly related only with non-living categories. The results showed that the definition of the latent variable expressing the substrate of non-living categories was less satisfactory than that expressing the living categories. On this basis, the conclusions of this study appear statistically definite but their psychological interpretation is less straightforward.

  5. PART BUILDING ORIENTATION OPTIMIZATION METHOD IN STEREOLITHOGRAPHY

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Aiming at the part quality and building time problems in stereolithography (SL) caused by unreasonable building orientation, a part building orientation decision method in SL rapid prototyping (RP) is carried out. Bringing into full consideration of the deformation, stair-stepping effect, overcure effect and building time related to the part fabrication orientation, and using evaluation function method, a multi-objective optimization model for the building orientation is defined. According to the difference in the angles between normal vectors of triangular facets in standard triangulation language (STL) model and z axis, the expressions of deformation area, stair-stepping area, overcure area are established. According to the characteristics in SL process, part building time is divided into four sections, that is, hatching scanning time, outline scanning time, support building time and layer waiting time. Expressions of each building time section are given. Considering the features of this optimization model, genetic algorithm (GA) is used to derive the optimization objective, related software is developed and optimization results are tested through experiments. Application shows that this method can effectively solve the quality and efficiency troubles caused by unreasonable part building orientation, an automatic orientation-determining program is developed and verified through test.

  6. 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.

  7. Pharmaceutical advertising and Medicare Part D.

    Science.gov (United States)

    Lakdawalla, Darius; Sood, Neeraj; Gu, Qian

    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.

  8. Uncertainty for Part Density Determination: An Update

    Energy Technology Data Exchange (ETDEWEB)

    Valdez, Mario Orlando [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    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.

    2013-01-01

    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.

    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.

  19. Sentence Clustering Using Parts-of-Speech

    Directory of Open Access Journals (Sweden)

    Richard Khoury

    2012-02-01

    Full Text Available Clustering algorithms are used in many Natural Language Processing (NLP tasks. They have proven to be popular and effective tools to use to discover groups of similar linguistic items. In this exploratory paper, we propose a new clustering algorithm to automatically cluster together similar sentences based on the sentences’ part-of-speech syntax. The algorithm generates and merges together the clusters using a syntactic similarity metric based on a hierarchical organization of the parts-of-speech. We demonstrate the features of this algorithm by implementing it in a question type classification system, in order to determine the positive or negative impact of different changes to the algorithm.

    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.

  10. Deburring capabilities for miniature precision parts

    Energy Technology Data Exchange (ETDEWEB)

    Gillespie, L.K.

    1976-09-01

    A study was initiated to determine which of 24 major deburring processes are applicable to the production of miniature precision metal components. Component parts of small precision mechanisms typically require near-sharp edges to assure reliable operation. A burr-free condition also is needed to minimize the possibility of the mechanism jamming in the event that burrs should break loose during operation. In the past, the reliable removal of machining burrs and the protection of the near-sharp part edges have dictated that deburring be performed only by hand. This method is inherently time-consuming and operator-variable. Specifically, the study sought to determine the manner in which the burr size affects the operating parameters of each deburring process, and the extent to which part size, surface finish, and edge radii are influenced by the various processes. Tests were performed on thirteen of the more promising processes. Of these, six were studied extensively, and reports on the individual investigations were published. A summary is given of the data that were obtained from tests which involved 30,000 measurements, a study of published literature, and discussions with hundreds of vendors and users of deburring equipment. The data presented describe the mechanism by which each process operates, define its uses and limitations, and provide the best possible estimate of its quantitative effects. This information can be used in the selection of a deburring process to meet specific part requirements. As a result of this investigation, the conclusion was reached that burrs having a major dimension of less than 25.4 ..mu..m (0.001 inch) can be removed by almost any process without adverse effects on part dimensions or surface finish.

  12. Visual object agnosia as a problem in integrating parts and part relations.

    Science.gov (United States)

    Saumier, Daniel; Arguin, Martin; Lefebvre, Christine; Lassonde, Maryse

    2002-01-01

    Current models of vision generally assume that the recognition of visual objects is achieved by encoding their component parts, as well as the spatial relations among parts. The current study examined how the processing of parts and their configurations may be affected in visual agnosia due to brain damage. Both a visual agnosic patient (AR) and healthy control subjects performed a visual search task in which they had to discriminate between targets and distractors that varied according to whether they shared their parts and/or their configuration. The results show that AR's visual search rates are disproportionally slow when targets and distractors share the same configuration than when they have different configurations. AR is also found to be disproportionately slow in discriminating targets and distractors that share identical parts when the targets and distractors share the same configuration. With differently configured targets and distractors, AR shows no part sharing effect. For controls, in contrast, the part and configuration sharing effects occur independently of one another. It is concluded that AR's object recognition deficit arises from difficulties in discriminating objects that share their configuration, and from an abnormal dependency of part information processing upon object configuration.

    Amran, M. A. M.; Idayu, N.; Faizal, K. M.; Sanusi, M.; Izamshah, R.; Shahir, M.

    2016-11-01

    In this study, the main objective is to determine the percentage difference of part weight between experimental and simulation work. The effect of process parameters on weight of plastic part is also investigated. The process parameters involved were mould temperature, melt temperature, injection time and cooling time. Autodesk Simulation Moldflow software was used to run the simulation of the plastic part. Taguchi method was selected as Design of Experiment to conduct the experiment. Then, the simulation result was validated with the experimental result. It was found that the minimum and maximum percentage of differential of part weight between simulation and experimental work are 0.35 % and 1.43 % respectively. In addition, the most significant parameter that affected part weight is the mould temperature, followed by melt temperature, injection time and cooling time.

  1. Parts Quality Management: Direct Part Marking via Data Matrix Symbols for Mission Assurance

    Science.gov (United States)

    Moss, Chantrice

    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 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. While this paper focuses on NASA programs, results may be applicable to a variety of industrial environments.

  2. Stochastic model of forecasting spare parts demand

    Directory of Open Access Journals (Sweden)

    Ivan S. Milojević

    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

  3. SELECTION OF METHOD FOR RESTORATION OF PARTS

    Directory of Open Access Journals (Sweden)

    V. P. Ivanov

    2016-01-01

    Full Text Available The paper contains definitions for a process and a methodology for restoration of parts on the basis of the analysis of the known methods and their selection. Geometric parameters and operational properties that should be provided for restoration of parts have been determined in the paper. A process for selection of the required method for restoration parts has been improved and it makes it possible to synthesize an optimal process of the restoration according to a criterion of industrial resource consumption with due account of quality, productivity and security limits. A justification on measures that meet the required limits has been presented in the paper. The paper shows a direction of technical solutions that ensure complete use of residual life of repair fund parts. These solutions can be achieved through close application of all repair sizes of work-pieces with revision of their values, uniform removal of the allowance while cutting the work-pieces at optimum locating, application of coating processes only in technically justified cases, application of straightening with thermal fixing of its results or all-around compression of deformable elements. The paper proposes to limit a number of overhauls for the units together with restoration of basic and fundamental parts by two repairs for the whole period of their lifetime. Number of shaft journal building-up should be limited by one building-up operation throughout the whole life cycle of the part with the purpose to preserve its length within the prescribed limits. It has been recommended to expand an application area of volumetric plastic deformation of material in the form of thermoplastic distribution or reduction of repair work-pieces representing class of rotation bodies with holes that ensures an allowance to machine external and internal surfaces for nominal dimensions without coating. A structure of the coating material with fine inclusions of carbides or nitrides of metals and

  5. Multi-part mask for implanting workpieces

    Energy Technology Data Exchange (ETDEWEB)

    Webb, Aaron P.; Carlson, Charles T.

    2016-05-10

    A multi-part mask has a pattern plate, which includes a planar portion that has the desired aperture pattern to be used during workpiece processing. The multi-part mask also has a mounting frame, which is used to hold the pattern plate. Prior to assembly, the pattern plate has an aligning portion, which has one or more holes through which reusable alignment pins are inserted. These alignment pins enter kinematic joints disposed on the mounting frame, which serve to precisely align the pattern plate to the mounting frame. After the pattern plate has been secured to the mounting frame, the aligning portion can be detached from the pattern plate. The alignment pins can be reused at a later time. In some embodiments, the pattern plate can later be removed from the mounting frame, so that the mounting frame may be reused.

  8. [Aerosinusitis: part 1: Fundamentals, pathophysiology and prophylaxis].

    Science.gov (United States)

    Weber, R; Kühnel, T; Graf, J; Hosemann, W

    2014-01-01

    The relevance of aerosinusitis stems from the high number of flight passengers and the impaired fitness for work of the flight personnel. The frontal sinus is more frequently affected than the maxillary sinus and the condition generally occurs during descent. Sinonasal diseases and anatomic variations leading to obstruction of paranasal sinus ventilation favor the development of aerosinusitis. This Continuing Medical Education (CME) article is based on selective literature searches of the PubMed database (search terms: "aerosinusitis", "barosinusitis", "barotrauma" AND "sinus", "barotrauma" AND "sinusitis", "sinusitis" AND "flying" OR "aviator"). Additionally, currently available monographs and further articles that could be identified based on the publication reviews were also included. Part 1 presents the pathophysiology, symptoms, risk factors, epidemiology and prophylaxis of aerosinusitis. In part 2, diagnosis, conservative and surgical treatment will be discussed.

  9. Acute Lower Gastrointestinal Bleeding: Part I

    Directory of Open Access Journals (Sweden)

    Robert Enns

    2001-01-01

    Full Text Available Acute lower gastrointestinal (LGI bleeding is typically caused by vascular malformations, diverticuli and neoplasia. Although endoscopic evaluation of the colon is relatively standard in stable patients with LGI bleeding, those with significant ongoing hemorrhage are often more difficult to evaluate endoscopically. Other investigative techniques such as nuclear scintigraphy, angiography and surgical exploration have been commonly used in unstable patients with LGI bleeding when the exact site is unknown. These investigative techniques have had variable measures of success. This two-part review evaluates the literature in an attempt to review the optimal investigative approach in patients with LGI hemorrhage, in particular patients who have had significant and ongoing bleeding. Part 1 of this article concentrates on the etiology of LGI hemorrhage, followed in a subsequent article by diagnostic and management strategies. Following the review, a consensus update will be included with guidelines for clinical use.

    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. Thus, while a prostitute will never receive a visa due to the danger that she represents, a football player will not only receive citizenship, but also a privileged place as raw material in the global marketplace.

  11. Neurofibromatoses: part 1 ? diagnosis and differential diagnosis

    Directory of Open Access Journals (Sweden)

    Luiz Oswaldo Carneiro Rodrigues

    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.

    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.

    Kongmunee, Chalermkwan; Chutima, Parames

    2016-05-01

    This research investigates the problem of the part supplier performance evaluation in a major Japanese automotive plant in Thailand. Its current evaluation scheme is based on experiences and self-opinion of the evaluators. As a result, many poor performance suppliers are still considered as good suppliers and allow to supply parts to the plant without further improvement obligation. To alleviate this problem, the brainstorming session among stakeholders and evaluators are formally conducted. The result of which is the appropriate evaluation criteria and sub-criteria. The analytical hierarchy process is also used to find suitable weights for each criteria and sub-criteria. The results show that a newly developed evaluation method is significantly better than the previous one in segregating between good and poor suppliers.

    This paper shows that budget deficits account for a relatively small fraction of debt growth and that stock-flow reconciliation, which is often considered a residual entity, is one of the key determinants of debt dynamics. After having explained the importance of the stock-flow reconciliation, the paper shows that this residual entity can be partly explained by contingent liabilities and balancesheet effects.

    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.

  9. “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.

    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.

    method used to design the 125-ton compressor is first reviewed and some related performance curves are predicted based on a quasi-3D method. In addition to an overall performance measurement, a series of instruments were installed on the compressor to identify where the measured performance differs from the predicted performance. The measurement techniques for providing the diagnostic flow parameters are also described briefly. Part II of this paper provides predictions of flow details in the areas of the compressor where there were differences between the measured and predicted performance.

  5. Coastal pollution emergency plan. Part I

    Energy Technology Data Exchange (ETDEWEB)

    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.

    An overview of the knowledge acquisition component of the Bauhaus, a prototype computer aided software engineering (CASE) workstation for the development of domain-specific automatic programming systems (D-SAPS) is given. D-SAPS use domain knowledge in the refinement of a description of an application program into a compilable implementation. The approach to the construction of D-SAPS was to automate the process of refining a description of a program, expressed in an object-oriented domain language, into a configuration of software parts that implement the behavior of the domain objects.

    2012-01-01

    A minority of asthma patients have disease that proves difficult to control with usual medications and experience ongoing symptoms, poor quality of life, and limitations in activity and/or frequent asthma exacerbations. This group of patients accounts for much of the expense associated with asthma care and is the focus of national and international collaborative study groups. Distinguishing between "difficult-to-manage asthma" and truly "therapy-resistant asthma" is helpful and promotes a systematic consideration of contributory factors. Critical evaluation of factors contributing to difficult-to-manage asthma including adverse environment, comorbidities, nonadherence, and incorrect diagnosis is recommended in a systematic fashion in Part 1 of this contribution.

    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.

  5. Diabetes mellitus, part 1: physiology and complications.

    Science.gov (United States)

    Nair, Muralitharan

    In part 1 of this 2-part article the author discusses the physiology and complications of diabetes mellitus (DM), a chronic and progressive disorder which affects all ages of the population. The number of people diagnosed with diabetes is approximately 1.8 million and an estimated further 1 million are undiagnosed (Department of Health, 2005). In the UK, 1-2% of the population have diabetes and among school children this is approximately 2 in 1000 (Watkins, 1996). There are two main types of diabetes--type 1 and type 2 (Porth, 2005). The aetiology of DM is unknown; however, genetic and environmental factors have been linked to its development. Type 1 results from the loss of insulin production in the beta cells of the pancreas, and type 2 from a lack of serum insulin or poor uptake of glucose into the cells. Diabetes causes disease in many organs in the body, which may be life-threatening if untreated. Complications such as heart disease, vascular disease, renal failure and blindness (Roberts, 2005) have all been reported. The increased prevalence may be caused by factors such as environmental aspects, diet, an ageing population and low levels of physical exercise.

    This is a second study of chiral anomaly induced transport within a holographic model consisting of anomalous $U(1)_V\\times U(1)_A$ Maxwell theory in Schwarzschild-$AdS_5$ spacetime. In the first part, chiral magnetic/separation effects (CME/CSE) are considered in presence of a static spatially-inhomogeneous external magnetic field. Gradient corrections to CME/CSE are analytically evaluated up to third order in the derivative expansion. Some of the third order gradient corrections lead to an anomaly-induced negative $B^2$-correction to the diffusion constant. We also find non-linear modifications to the chiral magnetic wave (CMW). In the second part, we focus on the experimentally interesting case of the axial chemical potential being induced dynamically by a constant magnetic and time-dependent electric fields. Constitutive relations for the vector/axial currents are computed employing two different approximations: (a) derivative expansion (up to third order) but fully nonlinear in the external fields, and (...

  7. Targeted development of registries of biological parts.

    Directory of Open Access Journals (Sweden)

    Jean Peccoud

    Full Text Available BACKGROUND: The design and construction of novel biological systems by combining basic building blocks represents a dominant paradigm in synthetic biology. Creating and maintaining a database of these building blocks is a way to streamline the fabrication of complex constructs. The Registry of Standard Biological Parts (Registry is the most advanced implementation of this idea. METHODS/PRINCIPAL FINDINGS: By analyzing inclusion relationships between the sequences of the Registry entries, we build a network that can be related to the Registry abstraction hierarchy. The distribution of entry reuse and complexity was extracted from this network. The collection of clones associated with the database entries was also analyzed. The plasmid inserts were amplified and sequenced. The sequences of 162 inserts could be confirmed experimentally but unexpected discrepancies have also been identified. CONCLUSIONS/SIGNIFICANCE: Organizational guidelines are proposed to help design and manage this new type of scientific resources. In particular, it appears necessary to compare the cost of ensuring the integrity of database entries and associated biological samples with their value to the users. The initial strategy that permits including any combination of parts irrespective of its potential value leads to an exponential and economically unsustainable growth that may be detrimental to the quality and long-term value of the resource to its users.

    Alexandrov, Natalia M.; Lewis, Robert Michael

    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.

    2012-03-01

    The cost of health care in the United States is increasing. In order to help control these rising costs, all parties involved in the delivery of health care, including dermatologists, need to be part of the solution of ethically reducing the cost of delivery of care. One potential means of meeting this goal is to increase the use of generic medications in daily practice. Generic medications can offer equally efficacious therapy at significantly lower prices, which can translate into large scale savings for the individual patient, the payer, and the overall health care system. Herein we provide an overview of new drug development, review the history of the generic drug industry, describe how generic drugs are approved by the US Food and Drug Administration, and define the concepts of bioequivalence and therapeutic equivalence. In part II, we explore various factors impacting generic drug use, provide cost analyses of dermatologic brand name and generic drugs, and review data addressing potential differences in the effectiveness of brand name versus generic drugs in dermatology. The cost of brand name and generic medications is highly variable by pharmacy, state, and payer. We used one source (www.drugstore.com) as an example and for consistency across all medications discussed herein. Prices included here may not reflect actual retail prices across the United States.

    2007-01-01

    Full Text Available In this paper, I investigate the categorial status of spatial terms in locative/directional expressions in Japanese. I will show that a certain class of spatial terms have a distinct categorial status from both regular postpositions and nouns. On one hand, syntactic diagnostics such as doubling, coordination by to, and co-occurrence with demonstratives indicate that these spatial terms belong to a nominal category rather than to a postpositional category. On the other hand, the fact that these spatial terms are modified by range modifiers indicates that they are more similar to regular postpositions than to nouns. On the basis of these diagnostics, I will argue that spatial terms in Japanese need to be assigned a new category Axial Part Phrase which is proposed by Svenonius 2006.

    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.

    Objective The aim of this study was to analyze the imaging features of alveolar soft part sarcoma (ASPS). Methods The imaging features of 11 cases with ASPS were retrospectively analyzed. Results ASPS mainly exhibited an isointense or slightly high signal intensity on T1-weighted imaging (T1WI), and a mixed high signal on T2-weighted imaging (T2WI). ASPS was partial, with rich tortuous flow voids, or “line-like” low signal septa. The essence of the mass was heterogeneous enhancement. The 1H-MRS showed a slight choline peak at 3.2 ppm. Conclusion The wel-circumscribed mass and blood voids, combined with “line-like” low signals play a significant role in diagnosis. The choline peak and the other signs may be auxiliary diagnoses.

Aerobots of various vehicle-types - CTOL, STOL, VTOL, and even possibly LTA - will be a part of a new paradigm for the distribution of goods and services. Aerobots as a class of vehicles may test the boundaries of aircraft design. New system analysis and design tools will be required in order to account for the new technologies and design parameters/constraints for such vehicles. The analysis tools also provide new approaches to defining/assessing technology goals and objectives and the technology portfolio necessary to accomplish those goals and objectives. Using the aerobot concept as an illustrative test case, key attributes of these analysis tools are discussed.

  2. Toxicological Models Part B: Environmental Models

    Science.gov (United States)

    Garric, Jeanne; Thybaud, Eric

    Assessment of ecotoxicological risks due to chemical substances is based in part on establishing concentration-response relationships for different organisms, including plants, invertebrates, and vertebrates living on land, fresh water, or sea water. European regulations for assessing the risks due to chemical products thus recommend the measurement of toxic effects on at least three taxons (algae, crustacea, fish) [1]. The assessment becomes more relevant when based upon a variety of different organisms, with a range of different biological and ecological features (autotrophic or heterotrophic, benthic or pelagic habitat, and different modes of reproduction, growth, respiration, or feeding, etc.), but also when it describes the effects of contaminants on sensitive physiological functions such as growth and reproduction, which determine the balance of populations of terrestrial and aquatic species in their environment.

    2016-07-01

    Synchrotron X-ray tomography (SXRT) has been applied to the study of defects within three-dimensional printed titanium parts. These parts were made using the Arcam EBM(®) (electron beam melting) process which uses powdered titanium alloy, Ti64 (Ti alloy with approximately 6%Al and 4%V) as the feed and an electron beam for the sintering/welding. The experiment was conducted on the Imaging and Medical Beamline of the Australian Synchrotron. The samples represent a selection of complex shapes with a variety of internal morphologies. Inspection via SXRT has revealed a number of defects which may not otherwise have been seen. The location and nature of such defects combined with detailed knowledge of the process conditions can contribute to understanding the interplay between design and manufacturing strategy. This fundamental understanding may subsequently be incorporated into process modelling, prediction of properties and the development of robust methodologies for the production of defect-free parts.

    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.

  7. Submodeling Simulations in Fusion Welds: Part II

    Bonifaz, E. A.

    2013-11-01

    In part I, three-dimensional transient non-linear sub modeling heat transfer simulations were performed to study the thermal histories and thermal cycles that occur during the welding process at the macro, meso and micro scales. In the present work, the corresponding non-uniform temperature changes were imposed as load conditions on structural calculations to study the evolution of localized plastic strains and residual stresses at these sub-level scales. To reach the goal, a three-dimensional finite element elastic-plastic model (ABAQUS code) was developed. The sub-modeling technique proposed to be used in coupling phase-field (and/or digital microstructures) codes with finite element codes, was used to mesh a local part of the model with a refined mesh based on interpolation of the solution from an initial, relatively coarse, macro global model. The meso-sub-model is the global model for the subsequent micro sub-model. The strategy used to calculate temperatures, strains and residual stresses at the macro, meso and micro scale level, is very flexible to be used to any number of levels. The objective of this research was to initiate the development of microstructural models to identify fusion welding process parameters for preserving the single crystal nature of gas turbine blades during repair procedures. The multi-scale submodeling approach can be used to capture weld pool features at the macro-meso scale level, and micro residual stress and secondary dendrite arm spacing features at the micro scale level.

    2010-01-01

    In Britain, part time employment is typically used to combine work and motherhood: 60% of employed mothers in Britain work part time, and this usually involves a transition from full time employment around the first childbirth. Part time jobs are often situated in lower level occupational groups and so a transition from full to part time employment may reduce the wage. Using the British Household Panel Survey this study investigates the wage impact of switching from full to part time employme...

    2014-01-01

    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. [Medicine in ancient Mesopotamia--part 1].

    Science.gov (United States)

    Martins E Silva, J

    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

  2. Parts of Speech Tagging for Afaan Oromo

    Getachew Mamo Wegari

    2011-09-01

    Full Text Available The main aim of this study is to develop part-of-speech tagger for Afaan Oromo language. After reviewing literatures on Afaan Oromo grammars and identifying tagset and word categories, the study adopted Hidden Markov Model (HMM approach and has implemented unigram and bigram models of Viterbi algorithm. Unigram model is used to understand word ambiguity in the language, while bigram model is used to undertake contextual analysis of words. For training and testing purpose 159 sentences (with a total of 1621 words that are manually annotated sample corpus are used. The corpus is collected from different public Afaan Oromo newspapers and bulletins to make the sample corpus balanced. A database of lexical probabilities and transitional probabilities are developed from the annotated corpus. These two probabilities are from which the tagger learn and tag sequence of words in sentences. The performance of the prototype, Afaan Oromo tagger is tested using tenfold cross validation mechanism. The result shows that in both unigram and bigram models 87.58% and 91.97% accuracy is obtained, respectively.

  3. Compressor Part II: Volute Flow Predictions

    Directory of Open Access Journals (Sweden)

    Yu-Tai Lee

    1999-01-01

    Full Text Available A numerical method that solves the Reynolds-averaged Navier-Stokes equations is used to study an inefficient component of a shipboard air-conditioning HCFC-124 compressor system. This high-loss component of the centrifugal compressor was identified as the volute through a series of measurements given in Part I of the paper. The predictions were made using three grid topologies. The first grid closes the connection between the cutwater and the discharge diffuser. The other two grids connect the cutwater area with the discharge diffuser. Experiments were performed to simulate both the cutwater conditions used in the predictions. Surface pressures along the outer wall and near the inlet of the volute were surveyed for comparisons with the predictions. Good agreements between the predicted results and the measurements validate the calculations. Total pressure distributions and flow stream traces from the prediction results support the loss distribution through the volute. A modified volute configuration is examined numerically for further loss comparison.

  4. Dignity and the use of body parts.

    Science.gov (United States)

    Foster, Charles

    2014-01-01

    This paper contends that the conventional ethical and legal ways of analysing the wrong involved in the misuse of human body parts are inadequate, and should be replaced with an analysis based on human dignity. It examines the various ways in which dignity has been understood, outlines many of the criticisms made of those ways (agreeing with many of the criticisms), and proposes a new way of seeing dignity which is exegetically consonant with the way in which dignity has been historically understood, and yet avoids the pitfalls which have led to dignity being dismissed by many as hopelessly amorphous or incurably theological. The account of dignity proposed is broadly Aristotelian. It defines dignity in terms of human thriving, and presupposes that it is possible, at least in principle, to determine empirically what makes humans thrive. It contends that humans are quintessentially relational animals, and that it is not possible (and certainly not ethically desirable) to define humans as atomistic entities. One important corollary of this is that when using dignity/thriving as a criterion for determining the ethical acceptability of a proposed action or inaction, one should ask not merely how the dignity interests of the patient (for instance) would be affected, but how the dignity interests of all stakeholders would be affected. The business of ethics is then the business of auditing all those interests, and determining the course of action which would maximise the amount of thriving in the world.

    2010-08-01

    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. Memory (RAM) is fundamentally semiconductor chips storing data and instructions for access by a CPU. RAM is classified by storage capacity, access speed, data rate, and configuration.

  7. Thermoforming of thermoplastic matrix composites. Part I

    Harper, R.C.

    1992-03-01

    Long-fiber-reinforced polymer matrix composites find widespread use in a variety of commercial applications requiring properties that cannot be provided by unreinforced plastics or other common materials of construction. However, thermosetting matrix resins have long been plagued by production processes that are slow and difficult to automate. This has limited the use of long-fiber-reinforced composites to relatively low productivity applications in which higher production costs can be justified. Unreinforced thermoplastics, by their very nature, can easily be made into sheet form and processed into a variety of formed shapes by various pressure assisted thermoforming means. It is possible to incorporate various types of fiber reinforcement to suit the end use of the thermoformed shape. Recently developed thermoplastic resins can also sometimes correct physical property deficiencies in a thermoset matrix composite. Many forms of thermoplastic composite material now exist that meet all the requirements of present day automotive and aerospace parts. Some of these are presently in production, while others are still in the development stage. This opens the possibility that long-fiber-reinforced thermoplastics might break the barrier that has long limited the applications for fiber-reinforced composites. 37 refs., 8 figs., 5 tabs.

  8. Bisphenol A in edible part of seafood

    Directory of Open Access Journals (Sweden)

    Adele Repossi

    2016-05-01

    Full Text Available 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.

    2014-05-01

    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 first part of this paper deals with the introduction of our Textile Research Centre in the field of composites and carbon fiber as a main material to produce three – dimensional textile structures. The use of composite materials in aerospace structures has increased over the past decades. Our contribution related to this field consists of the development of three- dimensional textile structures and even the adaptation and improvement of machinery to do it possible. Carbon fiber provides advantages as volumetric fraction and minimum fault occurrence. However carbon fiber has also disadvantages as uncomfortable handling delamination and high cost of material and processing.

    Dugan, Daniel C.

    2014-01-01

    Thrust control of Vertical Takeoff and Landing (VTOL) aircraft has always been a debatable issue. In most cases, it comes down to the fundamental question of throttle versus collective. Some aircraft used throttle(s), with a fore and aft longitudinal motion, some had collectives, some have used Thrust Levers where the protocol is still "Up is Up and Down is Down," and some have incorporated both throttles and collectives when designers did not want to deal with the Human Factors issues. There have even been combinations of throttles that incorporated an arc that have been met with varying degrees of success. A previous review was made of nineteen designs without attempting to judge the merits of the controller. Included in this paper are twelve designs entered in competition for the 1961 Tri-Service VTOL transport. Entries were from a Bell/Lockheed tiltduct, a North American tiltwing, a Vanguard liftfan, and even a Sikorsky tiltwing. Additional designs were submitted from Boeing Wichita (direct lift), Ling-Temco-Vought with its XC-142 tiltwing, Boeing Vertol's tiltwing, Mcdonnell's compound and tiltwing, and the Douglas turboduct and turboprop designs. A private party submitted a re-design of the Breguet 941 as a VTOL transport. It is important to document these 53 year-old designs to preserve a part of this country's aviation heritage.

    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.

    It has been shown that the MARLAP (Multi-Agency Radiological Laboratory Analytical Protocols) for estimating the Currie detection limit, which is based on 'critical values of the non-centrality parameter of the non-central t distribution', is intrinsically biased, even if no calibration curve or regression is used. This completed the refutation of the method, begun in Part 2. With the field cleared of obstructions, the true theory underlying Currie's limits of decision, detection and quantification, as they apply in a simple linear chemical measurement system (CMS) having heteroscedastic, Gaussian measurement noise and using weighted least squares (WLS) processing, was then derived. Extensive Monte Carlo simulations were performed, on 900 million independent calibration curves, for linear, 'hockey stick' and quadratic noise precision models (NPMs). With errorless NPM parameters, all the simulation results were found to be in excellent agreement with the derived theoretical expressions. Even with as much as 30% noise on all of the relevant NPM parameters, the worst absolute errors in rates of false positives and false negatives, was only 0.3%.

    ANSYS/CARES/PDS is a software system that combines the ANSYS Probabilistic Design System (PDS) software with a modified version of the Ceramics Analysis and Reliability Evaluation of Structures Life (CARES/Life) Version 6.0 software. [A prior version of CARES/Life was reported in Program for Evaluation of Reliability of Ceramic Parts (LEW-16018), NASA Tech Briefs, Vol. 20, No. 3 (March 1996), page 28.] CARES/Life models effects of stochastic strength, slow crack growth, and stress distribution on the overall reliability of a ceramic component. The essence of the enhancement in CARES/Life 6.0 is the capability to predict the probability of failure using results from transient finite-element analysis. ANSYS PDS models the effects of uncertainty in material properties, dimensions, and loading on the stress distribution and deformation. ANSYS/CARES/PDS accounts for the effects of probabilistic strength, probabilistic loads, probabilistic material properties, and probabilistic tolerances on the lifetime and reliability of the component. Even failure probability becomes a stochastic quantity that can be tracked as a response variable. ANSYS/CARES/PDS enables tracking of all stochastic quantities in the design space, thereby enabling more precise probabilistic prediction of lifetimes of ceramic components.

    2015-01-01

    As many as 53.5 million American workers have experienced workplace bullying, which can cost organizations an estimated $200 billion annually in lost productivity, increased sick d ays, increased med ical claims, legal costs, and staff turnover. Bullying can occur in any profession, but for many reasons it is most prevalent in healthcare. Bullying behavior in healthcare has been reported and documented in literature for over 35 years. Although physicians are often considered to be the primary culprit of bullying, healthcare bullies can be one any one of the professionals who work in the organization including nurses, radiology technologists, pharmacists, ancillary staff personnel, administrators, or other non-physician staff members. The first installment of the series focused on defining bullying and its impact on the organization. Part 2 discussed three legal protections for the bully to include at-will laws, unions, and bylaws related to physician privileging. The final installment in this series will evaluate specific bully types and implementing processes to address inappropriate behavior.

    Murine brain is an excellent tool for studying protein expression and brain function in mammals. Although mice are an extensively used model to recapitulate various pathological conditions, the proteome of the normal mouse brain has not been yet reported. In the present study, we identified the total proteins of different parts of the brain of CB7BL/6 mice, a widely used strain, by applying proteomic methodologies. The adult mouse brain was dissected anatomically into the following regions: frontal cortex, olfactory bulb, hippocampus, midbrain, cerebellum, hypothalamus and medulla. Total protein extracts of these regions were separated by two-dimensional gel electrophoresis and analyzed by matrix-assisted laser desorption ionisation time-of-flight mass spectrometry, following in-gel digestion with trypsin. Protein identification was carried out by peptide mass fingerprint. Thus, 515 different single-gene products were identified in total, 54 expressed specifically in the olfactory bulb, 62 in the hippocampus, 36 in the frontal cortex, five in the cerebellum, nine in the midbrain, eight in the hypothamamus and 10 in the medulla. The majority of the proteins were enzymes, structural proteins and transporters. Moreover, the distribution of these molecules appears to exhibit direct correlation with the function of the brain regions where they were expressed. This study leads to the complete characterization of the normal mouse brain proteome as well as the protein expression profile of the different brain regions. These results will aid in addressing unmet scientific needs regarding physiological and pathological brain functions.

  19. Integrated concurrent utilization quality review, Part 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.

  20. Lipids: Part of the tangled web

    Energy Technology Data Exchange (ETDEWEB)

    Krauss, R.M.

    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.

    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.

  4. 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

  5. The genus Allium--Part 3.

    Fenwick, G R; Hanley, A B

    1985-01-01

    Allium is a genus of some 500 species belonging to the family Liliaceae. However, only a few of these are important as food plants, notably onion, garlic, chive, leek, and rakkyo. Such plants have been used for many centuries for their pungency and flavoring value, for their medicinal properties, and in some parts of the world, their use also has religious connotations. The flavors of members of alliums, in addition to being characteristic, are also complex, being derived enzymically from a number of involatile precursors. As well as there being variation of flavor between different alliums there are also considerable changes that occur as a result of cooking and processing. These are, of course, of importance to the consumer and food technologist/processor. The review will introduce the subject by an historical perspective and will set against this data on the present cultivation and usage of commercially cultivated alliums. The chemical composition of these plants will be discussed, emphasis being given to nonvolatile constituents which are, perhaps, less often considered. Discussion of the volatile constituents, which will include mention of the methods currently used for their analysis and for the determination of "flavor strength," will be mainly concerned with literature taken from the last 5 years. In considering the extent and nature of allium cultivation and processing, factors affecting the nutritional value and quality will be highlighted. The medicinal properties of garlic and onion oils have been extensively studied over the last decade and the review will include critical assessment of this area; it will also touch on the more general properties (antimicrobial, antifungal, antibacterial, and insecticidal) of these oils. Finally, mention will be made of the antinutritional, toxic, or otherwise undesirable effects of alliums, for example, as inadvertant components of animal diets, tainting of milk, and other food products. It is our intention to review

    Full Text Available Late Wordian (Guadalupian brachiopods from Member 2 of the Panjshah Formation in the Karakorum (N Pakistan are described. The brachiopod assemblage, dated by the associated fusulinids and conodonts, consists of 29 genera (3 of which are questionable and 1 unidentifiable of the orders Productida, Orthida, Rhynchonellida, Athyridida, Spiriferida and Terebratulida. Hunzininae, a new subfamily of the Spiriferellidae is proposed; it includes Darbandia n. gen., with type species D. vagabunda n. sp. and Elivina chapursani n. sp. A third new species is assigned to the genus Anchorhynchia of the family Wellerellidae: A. cimmerica n. sp.A quantitative biostratigraphic analysis demonstrates two major faunal changes in the Elivina chapursani- Chapursania tatianae Assemblage Zone of the upper part of Member 2, which are not strictly linked to lithological changes. This biozone is correlated with the brachiopod faunas of the Gnishik Formation of Armenia and those of the basal Takhtabulak Formation of SE Pamir.The faunal elements of the Elivina chapursani- Chapursania tatianae Assemblage Zone are an admixture of wide-ranging, Tethyan (particularly abundant, Gondwanan and endemic (Cimmerian genera, representing a transitional fauna and a biostratigraphic tool for intercontinental correlation, which are particularly problematic in this time interval. The Panjshah transitional fauna demonstrates the persistence of the Transhimalayan Province of the Cimmerian Region into the late Guadalupian, which originated at the end of the Cisuralian and occupied Armenia, Central Afghanistan, Karakorum and SE Pamir. It provides also some insights into the biodiversity pattern before the mass extinction at the end of the Guadalupian, and suggests that this event was as rapid as the end- Permian mass extinction, at least in Central Asia.

    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.

    2008-01-01

    Balanced flow meters are recent additions to an established class of simple, rugged flow meters that contain no moving parts in contact with flow and are based on measurement of pressure drops across objects placed in flow paths. These flow meters are highly accurate, minimally intrusive, easily manufacturable, and reliable. A balanced flow meter can be easily mounted in a flow path by bolting it between conventional pipe flanges. A balanced flow meter can be used to measure the flow of any of a variety of liquids or gases, provided that it has been properly calibrated. Relative to the standard orifice-plate flow meter, the balanced flow meter introduces less turbulence and two times less permanent pressure loss and is therefore capable of offering 10 times greater accuracy and repeatability with less dissipation of energy. A secondary benefit of the reduction of turbulence is the reduction of vibration and up to 15 times less acoustic noise generation. Both the balanced flow meter and the standard orifice-plate flow meter are basically disks that contain holes and are instrumented with pressure transducers on their upstream and downstream faces. The most obvious difference between them is that the standard orifice plate contains a single, central hole while the balanced flow meter contains multiple holes. The term 'balanced' signifies that in designing the meter, the sizes and locations of the holes are determined in an optimization procedure that involves balancing of numerous factors, including volumetric flow, mass flow, dynamic pressure, kinetic energy, all in an effort to minimize such undesired effects as turbulence, pressure loss, dissipation of kinetic energy, and non-repeatability and nonlinearity of response over the anticipated range of flow conditions. Due to proper balancing of these factors, recent testing demonstrated that the balanced flow-meter performance was similar to a Venturi tube in both accuracy and pressure recovery, but featured reduced

    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.

    Based on the inner character analysis of interpart, detail modification and assembly relation of mechanical connecting element, the idea, which extends the feature modeling of part to the interpart feature modeling for assembly purpose, is presented, and virtual-part-based connecting element modeling is proposed. During the assembly modeling, base parts are modified by the Boolean subtraction between the virtual part and the part to be connected. Dynamic matching algorithm, which is based on list database, is designed for dynamic extension and off-line editing of connecting part and virtual part, and design rules of connecting element is encapsulated by the virtual part. A prototyped software module for rapid design of connecting elements is implemented under self-developed CAD/CAM platform-SuperMan.

    Alternate aviation fuels for military or commercial use are required to satisfy MIL-DTL-83133F(2008) or ASTM D 7566 (2010) standards, respectively, and are classified as drop-in fuel replacements. To satisfy legacy issues, blends to 50% alternate fuel with petroleum fuels are certified individually on the basis of feedstock. Adherence to alternate fuels and fuel blends requires smart fueling systems or advanced fuel-flexible systems, including combustors and engines without significant sacrifice in performance or emissions requirements. This paper provides preliminary performance (Part A) and emissions and particulates (Part B) combustor sector data for synthetic-parafinic-kerosene- (SPK-) type fuel and blends with JP-8+100 relative to JP-8+100 as baseline fueling.

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.
