    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.

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.

Impulsan el desarrollo y/o mejora de l infraestructura de servicios. Modifican los procesos de segregación social y fragmentación espacial, acorde a los actuales procesos urbanos. Las barreras físicas se convierten en barreras sociales y marcan profundas diferencias entre quienes viven adent y quienes viven afuera. Finalmente, estas urbanizaciones ocupan superficies pe ueñas en comparación con las extensiones ocupadas por los emprendimientos construidos en las grandes ciudades, situación que, a su vez, limita el tamaño de los espacios ofrecidos.

    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.

    In the present work a contribution to the study of the quantification of the radiation of the structure walls in systems of closed box has been made, establishing a relation of the vibroacustic response of this type of radiating systems with the characteristics of the material used, such as the Young modulus, the damping, or the density. From a general point of view, the object of the work fits within the problems of dynamic fluid-structure interaction, so the presented foundations of the procedures and models, are similar to the used in other dominions of application, like the construction, aeronautics, naval construction, Biology, etc. In order to approach the problem, a mecano-acoustic couple between the different elements from the radiating system is considered. Ideally, in the radiating systems composed of loudspeakers mounted on an acoustic enclosure or box, the walls of the box are considerated infinitely rigid with null movement. In the reality, the experience demonstrates that the walls behave like vibrant plates under the action of the inner pressures, and contribute to the final radiation of sound of the system, mainly in the low frequencies range. To obtain the proposed objective, first a series of experimental measures has been made on models of closed box with and without loudspeaker. In the experimental procedure the vibracional behavior of the walls of the structure has been studied by means of modal analysis and measures of vibration. The acoustic response of the systems is evaluated by means of measures of acoustic pressure and intensity. Next, numerical models of the loudspeaker, inner air and structure have been implemented. The implemented numerical models are mechanical-acoustic, the electrical part of the loudspeaker has been replaced by a harmonic excitation force. The first numerical model is three-dimensional, looking for obtaining a simulation of the simultaneous interaction of the three main elements of the system: the inner air of the

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.

    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.

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.

    Full Text Available Se ha desarrollado una herramienta informática que permite llevar a cabo el diseño y determinar la operación de bombas de calor por compresión mecánica de tipo "partido" (split. 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.

    Full Text Available A lise das hemácias, de causa imune ou não imune, pode provocar a elevação da hemoglobina plasmática induzindo efeitos deletérios principalmente nos rins e no sistema cardiovascular. 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.

    In this paper the development of a computer tool for the analysis of centrifugal pumps is presented. This tool allows the user to analyze the performance of the pump by means of the analysis of the behavior curves at its design conditions, reference and operation. In order to realize the analysis it is necessary that the user feeds the tool with the missing and necessary information according to norm ASME PTC 8.2 and under the specified conditions of calibration of the same norm, to eliminate possible errors in the results, a bad qualification or erroneous acquisition of the signals. The system must early be fed with the polynomials of the behavior curves of the pump in its design conditions to later correct the behavior based on a velocity of present operation.

La experimentación se realiza en un banco dedicado que permite cavitar a una bomba de ½ hp en distintos niveles de severidad y bajo diferentes condiciones de bombeo. Resultados experimentales mostraron que los indicadores propuestos permiten detectar y evaluar cualitativamente los niveles de severidad de la cavitación en una bomba centrífuga.In this paper an acoustic emission based cavitation fault detection system is proposed for a centrifugal pump. The monitoring is performed tracking a fault indicator obtained using the RMS value of the acoustic emission signal in time domain and the RMS value of the coefficients obtained by applying discrete wavelet transform on the acoustic signal using db6 mother wavelet. Experiments in different cavitation levels and under different operation conditions are carried out in a ½ hp centrifugal pump dedicated test bed. Results showed that the proposed fault indicators are suitable for detecting and evaluating cavitation severities in a centrifugal pump.

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.

    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 O presente trabalho tem por finalidade apresentar as etapas de um projeto para construção de uma bomba-balâo para contrapulsação aórtica. Desenvolveram-se três protótipos, sendo que os dois primeiros utilizavam ar comprimido e vácuo hospitalares para insuflação e deflação do cateter-balão. Esses dois protótipos apresentavam como diferenças fundamentais: o tipo de dispositivo que captava o sinal luminoso da onda R do ECG utilizado para a sincronização do bombeamento; o tipo de válvula solenóide e os componentes eletrônicos de maior resolução utilizados no segundo protótipo. O terceiro e atual protótipo passou a obter o sinal da onda R diretamente da saída de cardioversão do monitor de ECG e substituiu o ar comprimió e o vácuo hospitalares, além das válvulas solenóides, por uma bomba eletromagnética. Está em fase de resolução o problema de deflação tardia que ainda ocorre no sistema.The present paper presents the project and construction of a balloon-pump for aortic counterpulsation. Three experimental models were developed, the first two using hospital air and vacuum lines for inflation and deflation of the balloon catheter. These two inicial models diffères among themselves in the mechanism used to capture the light signal corresponding to the R wave of the ECG, which was used to sincronize the pumping. The solenoid valve and electronic components were of higher resolution in the second model. The third and present model recieves the R wave signal from the cardioversor adaptor of ECG monitor and the hospital vacuum and air lines along with the solenoid valve were substituted by an electromagnetic pump. The problems related to late deflation that have ocurred in the system are still in study. Emphasis is given on the importance of this research, which has incremented knowledge for the construction of other medical equipment, mainly in the area of respiratory care.

    Full Text Available Los inhibidores de la bomba de protones (IBP son fármacos útiles para el control de la patología asociada con la acidez gástrica, patología con una alta prevalencia dentro de la población general. En las Unidades de dolor tratamos pacientes con pluripatología y polimedicados, entre ellas patologías asociadas con la acidez gástrica. Así como también utilizamos fármacos como AINES, glucocorticoides, bifosfonatos... que pueden reactivar, empeorar la patología ligada a la acidez. El conocimiento de los aspectos farmacológicos de los IBP, tanto farmacocinéticos como farmacodinámicos, es necesario y preciso para poder elegir el más adecuado para nuestros pacientes con pluripatologia y polimedicados evitando las posibles interacciones farmacológicas que podrían afectar al estado de salud de nuestros pacientes.Protón Pump Inhibitors (PPIs have shown their usefulness in the treatment of acid-related disorders, highly prevalent in normal population. Pain units are used to treating patients with a wide range of diseases, including acid related-disorders, who are also being prescribed many different drugs, like NSAIDs, corticosteroids or biphosponates, which may reactívate or even worsen acid-related disorders. Knowledge of the pharmacological aspects of PPIs, both their pharmacokinetics and pharmacodynamics, is needed to properly choose the one which fits most to our multi-pathologic, multi-treated patients, in order to avoid possible pharmacological interactions than could endanger their health condition.

    Ingrid Martínez

    Full Text Available Clopidogrel, una tienopiridina, es un antiagregante plaquetario que en la actualidad constituye la piedra angular del tratamiento médico en pacientes que presentan eventos coronarios agudos. Es una prodroga que debe ser convertida en la forma activa a nivel hepático, por la isoenzima CYP2C19. Recientemente, se ha llamado ampliamente la atención sobre la probable interacción entre los inhibidores de la bomba de protones y el clopidogrel por la inhibición competitiva que estos hacen sobre el sistema enzimático hepático activador de clopidogrel, que causa disminución de la eficacia del mismo como antitrombótico. Sin embargo, la evidencia sobre esta interacción es contradictoria y hasta el momento no se han realizado ensayos clínicos para resolver esta duda. Si se necesita utilizar un IBP en pacientes que utilizan clopidogrel, se recomienda el pantoprazol o el esomeprazol por la mínima inhibición que ejercen sobre el CYP2C19.Clopidogrel, a thienopyridine, is an antiplatelet drug which currently represents the cornerstone for the treatment of acute coronary events. It is a pro-drug that must be converted at hepatic level into its active form by the CYP2C19 isoenzyme. Recently the interaction between proton pump inhibitors and clopidogrel has been widely brought to attention. The competitive inhibition that these generate on the hepatic enzymatic system probably activates clopidogrel, thus causing a decrease in its effectiveness as an antithrombotic. Nevertheless, evidence is contradictory, and until now no clinical trials have been performed to clear up doubts. If a PPI is to be used on patients who take clopidogrel, the use of Pantoprazole or Esomeprazole is recommended because they exert minimal inhibition on CYP2C19.

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

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

All animals underwent collection of gastric material samples, after stomach removal, by either biopsies, or aspirates, or swabs. Samples were bacteriologically processed in order to identify species and strains. Values are described as natural logarithm of colony former units per mL [Ln(CFU/mL]. Kruskal-Wallis and Mann-Whitney non-parametric tests were used, and pOBJETIVO: Avaliar modelos de coleta de material gástrico de ratos da linhagem Wistar, com e sem o uso de inibidores de bomba de próton (IBPs. MÉTODOS: 24 ratos foram submetidos a tratamento com omeprazol intraperitoneal e 12 outros ratos receberam tratamento semelhante com solução salina a 0,9%. Os animais foram submetidos a coleta de amostras de material gástrico, após retirada do estômago, utilizando-se de biópsias, aspirados ou swabs. Os materiais obtidos foram processados bacteriologicamente para identificação de espécimes quanto ao gênero. Os valores são descritos em logaritmo natural das unidades formadoras de colônias por mL [Ln(UFC/mL]. Utilizou-se os testes não-paramétricos de Kruskal-Wallis e Mann-Whitney, considerando-se p<0,05 como estatisticamente significativo. RESULTADOS: Não se observou diferença significativa da quantidade de Ln(UFC/mL entre os três métodos de coleta, independente do uso de omeprazol. Também não se observou diferença significativa de Ln(UFC/mL ao comparar-se os métodos individualmente entre si nas condições de uso de omeprazol ou placebo. Houve aumento significativo da variedade de gêneros de bactérias com o uso de IBP, nos 3 métodos de coleta, sendo isto mais perceptível na biópsia e swab.

    In the early design period, estimation of the part or the whole product machinability is useful to consider the function and process request of the product at the same time so as to globally optimize the design decision. This paper presents a part machinability evaluation system, discusses the general restrictions of part machinability, and realizes the inspection of these restrictions with the relation between tool scan space and part model. During the system development, the expansibility and understandability were considered, and an independent restriction algorithm library and a general function library were set up. Additionally, the system has an interpreter and a knowledge manager.

  6. Controlled parts management

    International Nuclear Information System (INIS)

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

  3. Concern for older parts

    International Nuclear Information System (INIS)

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

  8. Measurement of cylindrical parts

    Science.gov (United States)

    Knight, Paul Douglas, Jr.

    The form of cylindrical parts has been traditionally evaluated using stylus-based mechanical instruments. The Tropel Corporation has developed a grazing incidence interferometer (GII) for the measurement of cylindrical parts. The repeatability of this instrument due to various instrument uncertainties was measured. Differing instrument configurations that produce the same systematic error were determined to produce a zonal calibration method for determining systematic error over the full range of the instrument, given knowledge of the error in a single zone. The effect of the aperture stop on the response of the imaging system to axially sinusoidal artifacts was simulated. Diamond-turned axially sinusoidal artifacts, with amplitude of order1 um and spatial wavelength of order10 mm, were measured to test the axial response of the interferometer. The modulation transfer function of the instrument's imaging system, measured using a knife edge test, predicts the response observed with the sinusoidal artifacts. A diffraction analysis predicts that the measured axial form is modified by a second order envelope function with phase that varies with the relative position of the imaging system focal plane and part position. A compensation method is proposed for this effect. A comparison of roundness measurements by both a traditional stylus-based instrument and the GII was performed demonstrating that the roundness measurements of the two instruments are equivalent when the measurements are properly corrected for the differing effects of surface finish.

  13. Invisible parts of attractors

    International Nuclear Information System (INIS)

    This paper deals with attractors of generic dynamical systems. We introduce the notion of ε-invisible set, which is an open set of the phase space in which almost all orbits spend on average a fraction of time no greater than ε. For extraordinarily small values of ε (say, smaller than 2−100), these are large neighbourhoods of some parts of the attractors in the phase space which an observer virtually never sees when following a generic orbit. For any n ≥ 100, we construct a set Qn in the space of skew products over a solenoid with the fibre a circle having the following properties. Any map from Qn is a structurally stable diffeomorphism; the Lipschitz constants of the map and its inverse are no greater than L (where L is a universal constant that does not depend on n, say L n has a 2−n-invisible part of its attractor, whose size is comparable to that of the whole attractor. The set Qn is a ball of radius O(n−2) in the space of skew products with the C1 metric. It consists of structurally stable skew products. Small perturbations of these skew products in the space of all diffeomorphisms still have attractors with the same properties. Thus for all such perturbations, a sizable portion of the attractor is almost never visited by generic orbits and is practically never seen by the observer

  14. Mapping sequences by parts

    Directory of Open Access Journals (Sweden)

    Guziolowski Carito

    2007-09-01

    Full Text Available Abstract Background: We present the N-map method, a pairwise and asymmetrical approach which allows us to compare sequences by taking into account evolutionary events that produce shuffled, reversed or repeated elements. Basically, the optimal N-map of a sequence s over a sequence t is the best way of partitioning the first sequence into N parts and placing them, possibly complementary reversed, over the second sequence in order to maximize the sum of their gapless alignment scores. Results: We introduce an algorithm computing an optimal N-map with time complexity O (|s| × |t| × N using O (|s| × |t| × N memory space. Among all the numbers of parts taken in a reasonable range, we select the value N for which the optimal N-map has the most significant score. To evaluate this significance, we study the empirical distributions of the scores of optimal N-maps and show that they can be approximated by normal distributions with a reasonable accuracy. We test the functionality of the approach over random sequences on which we apply artificial evolutionary events. Practical Application: The method is illustrated with four case studies of pairs of sequences involving non-standard evolutionary events.

    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.

    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.

    This paper presents hydrothermal quartz with macroscopic planar parting from the Mesoproterozoic Modum complex in southern Norway. Similar macroscopic parting in hydrothermal quartz with macroscopic planar structures has only been described from two localities in the world; Madagascar (Flörke et al., 1981) and Southern California (Murdoch et al., 1938). The study area consists of well foliated and banded sillimanite- garnet- amphibolite- mica gneiss that is cut at high angle by hydrothermal veins containing albite, chlinoclore, hornblende, hydroxyl apatite and quartz. The rim of the veins is generally made up of almost pure end-member euhedral albite. Then there is vugs with euhedral hornblende (10-25cm long) and euhedral hydroxyl apatite with size ranging from mm scale to several cm. Some places the quartz encloses apatite and hornblende. The quartz is anhedral, inequigranular with undulose extinction bordering sub grain rotation. It has large planar penetrative parting faces with pearly luster; however this is not consistent throughout the outcrop and some places the penetrative faces disappears and the quartz has a conchoidal fracture. The planar faces continue throughout the specimens with a few mm spacing. Thin sections oriented perpendicular to the most pronounced planar structure show lamellas that extinguishes at small angles (2 degrees) to each other. EBSD mapping of the planar faces shows two orientations {0-111} and {1-101}, corresponding to the r- and z-faces respectively, separated by irregular boundaries. The misorientation between these two crystallographic orientations on the parting is a 60 degree rotation on [0 0 1] in correspondence to the dauphiné twin law. Investigations conducted on thin sections cut orthogonal to the parting shows that the parting cuts and offsets the dauphiné twins, indicating a late genesis of the parting. However some internal stress induced movement of the twins are visible. SEM-CL documents three generations of quartz

  2. Part Fixturing For Diamond Machining

    Science.gov (United States)

    Chaloux, Leonard E.

    1984-12-01

    Successful production of diamond turned components can be extremely dependent on the fixturing used to support the workpiece during the machining operation. Typical fixturing methods include vacuum chucking, air chucking and mechanical clamping. Depending on the type of part to be machined, suggested fixturing methods can vary widely. For example, a part requiring a flycut surface is not subject to the centrifugal forces and balance requirements of a part that must be turned about an axis of rotation. Therefore, in many cases the fixturing required for flycutting may be much simpler than that required for turning. In all cases, there are general guidelines that should be followed to determine the best method of fixturing.

    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 are not...... 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. Focusing the partly polarized light

    2015-11-01

    The paper presents the mathematical technique for calculation of three dimensional intensity distribution near a focal point of an optical system in case of partly polarized light. The proposed technique considers a high aperture optical system that focuses a partly polarized parallel beam. The principal idea is based on Huygens-Fresnel principle: a spherical wave at an exit pupil of an optical system is considered as a numerous set of secondary light point sources. Each source emits a partly polarized spherical wave. The polarization orientation of each wave can be calculated using angular pupil coordinates. Modulation of amplitude, phase or polarization can be introduced depending on these pupil coordinates. The total intensity is defined as superposition of complex wave amplitudes taking into account polarization orientation, degree of polarization and orientation of detector aperture. The paper presents the intensity distributions calculated for beams with various types and degrees of polarization.

  15. 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.

  16. CERN: Real and imaginary parts

    International Nuclear Information System (INIS)

    Full text: Elastic scattering (where particles bounce off each other) has implications which go far beyond the deceptive simplicity and inconsequence of this process. Several years ago, an elastic scattering result by the UA4 experiment at CERN's proton-antiproton collider (January 1988, page 32) set the high energy world talking. In quantum mechanics, the forward elastic scattering amplitude is a complex number whose real and imaginary parts can be related. The powerful 'optical theorem' relates the total reaction rate (cross-section) to the imaginary part of the forward scattering amplitude, while the ratio of the real and imaginary parts gives an indication of where the total reaction rate is going at higher energies, independent of what the actual mechanisms are. Thus, for example, elastic scattering measurements at CERN's Intersecting Storage Rings pointed the way to the behaviour eventually seen at the proton-antiproton collider. In the 1985 run, UA4 found the ratio (rho) between the real and the imaginary parts to be 0.24, about twice the theoretical prediction. At face value, this suggested that the total reaction rate would increase dramatically at higher collision energies. With such a prediction at stake, confirmation with a more precise measurement was necessary and the UA4/2 experiment (Genoa/ Palaiseau/Prague/Rome/Valencia collaboration) was launched. The real part of the scattering amplitude is obtained via measurements of elastic scattering in a four momentum transfer domain where strong and electromagnetic interactions are comparable. This corresponds to scattering angles of 100 microradians, with the detectors inside ''Roman pots'' close to the circulating beams, and using special beam optics. The new experiment took place in a five-week run late in 1991. With the Roman pots within 2mm of the beams, about a million elastic events were recorded. Several months later, a special dedicated run fixed the SPS

  3. Automotive stamped part fatigue design

    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.

    Full Text Available The increased use of small gas turbines and turbochargers in different technical fields has led to the development of highly-loaded centrifugal compressors with extremely thin blades. Due to the high rotational speed and the corresponding centrifugal load, the shape of the impeller hub must also be optimized. This has led to a reduction of the thickness of the impeller disc in the outlet region. The thin parts of the impeller are very sensitive and may be damaged by the excitation of dangerous blade vibrations.

    2016-04-27

    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.

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.

    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. PMID:26083891

    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.

    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

  16. Commercial Parts Technology Qualification Processes

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

    Full Text Available Muchos años estuvimos resistiéndonos a aceptar la difícil situación que en todos los órdenes vivía el país. Finalmente, y como consecuencia de intereses ajenos a los que realmente debían guiarnos, estalló o quizá sea mejor decir, se agudizo la crisis del sistema. El tema no es nuevo, y recabar sobre el mismo, no pasaría, en el mejor de los casos, de ser un simple mea-culpa que dudamos aporte luces a la solución del problema. Sin embargo, pretender cerrar los ojos frente a la crisis, también resulta imposible, y mas aun, cuando la consecuencia directa de ella se refleja en la perdida, cada vez mayor, de confianza de la ciudadanía en todos los estamentos de la nación, pero fundamentalmente porque institucionalmente somos parte de ella.

  18. 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.

  20. [First part: the intestinal microbiota].

    Science.gov (United States)

    Capurso, Lucio

    2016-06-01

    The human gastrointestinal tract contains a large number of commensal (non pathogenic) and pathogenic microbial species that have co-evolved with the human genome and differ in composition and function based on their location, as well as age, sex, race/ethnicity, and diet of their host and we can in fact consider the human body as a mix of human and bacterial cells. It is now evident that the large intestine is much more than an organ for waste material and absorption of water, salts and drugs, and indeed has a very important impact on human health, for a major part related to the specific composition of the complex microbial community in the colon. In man, the large gut receives material from the ileum which has already been digested and the contents are then mixed and retained for 6-12 hours in the caecum and right colon. Thus, the large intestine is an open system, with nutrients flowing in the caecum, and bacteria, their metabolic products, and undigested foodstuffs being excreted as faeces. The anaerobic brakdown of carbohydrate and protein by bacteria is known conventionally as fermentation. In man the major end products are the short-chain fatty acids (SCFA) acetate, propionate, butirate, the gases H2 and CO2, ammonia, amines, phenols and energy, which the bacteria use for growth and the maintenance of cellular function. The microbiota is also an important factor in the development of the immune response. The interaction between the gastrointestinal tract and resident microbiota is well balanced in healthy individuals, but its breakdown can lead to intestinal and extraintestinal disease.

  7. Changing nature of equipment and parts qualification

    International Nuclear Information System (INIS)

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

    Full Text Available The increasing number of parts variants on an assembly line requires an improvement for a cost efficient and flexible parts supply system. 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. Finally, we present the lean approach in the minomi concepts that used in designing the component racks.

    Before the recent economic crisis, part-time employment was very low in Hungary. During the crisis, however, the most rapid increase in the number of part-time employees within the European Union was observed in Hungary. Part-time employment increased in a number of European Union countries for cyclical reasons: companies hoarded labour – usually with government assistance – by reducing the number of per capita hours worked instead of laying off workers. At the same time, part-time labour sup...

  14. Metallic parts fabrication using the SIS process

    Science.gov (United States)

    Mojdeh, Mehdi

    Since early 1980s, quite a few techniques of Rapid Prototyping (RP), also known as Layered Manufacturing, have been developed. By building three-dimensional parts in a layer-by-layer additive manner, these techniques allow freeform fabrication of parts of complex geometry. Despite recent advances in fabrication of polymer parts, most of the existing rapid prototyping processes are still not capable of fabrication of accurate metallic parts with acceptable mechanical properties. Insufficient dimensional accuracy, limited number of materials, proper mechanical properties, required post machining and lack of repeatability between builds have greatly limited the market penetration of these techniques. This dissertation presents an innovative layered manufacturing technique for fabrication of dense metallic parts called Selective Inhibition Sintering (SIS), developed at the University of Southern California. The SIS-Metal technology adapts RP capabilities and extends them to the field of fabrication of metallic parts for a variety of applications such as tooling and low volume production. Using this process, a metallic part, with varying 3 dimensional geometries, can be automatically constructed from a wide range of materials. SIS-Metal is the only RP process which is suitable for fabrication of dense, complex shaped, accurate objects using a variety of materials. In the SIS-Metal process a metallic part is built layer by layer by deposition for each layer of an inhibitor material which defines the corresponding layer boundary and then filling the voids of the created geometry with metal powder; and compacting the layer formed to reach a high powder density. The resulting green part is then sintered in a furnace to yield the final functional part. In this research different inhibition techniques were explored and a series of single and multi layer parts was fabricated using the most promising inhibition technique, namely, macro-mechanical inhibition.

  15. An inertial sensor for parts inspection

    OpenAIRE

    Tam, SM; Cheung, KC

    1995-01-01

    This paper describes the development of a sensor which performs parts inspection by measuring the inertial properties of the part. The sensor comprises a measuring platform supported on a column which is fixed to a rigid base. The part under inspection is attached to the platform to form a single body. By measuring the static deflections of the column and the natural frequency of vibration of the system, it is possible to determine the spatial location of the centre of mass of the part.

  16. Rotor instability due to loose rotating part

    Science.gov (United States)

    Muszynska, A.

    1985-01-01

    Loosening of a rotating part from its fixed position on the shaft or a part of the stator which comes loose and begins to turn with the rotor very frequently represents machinery malfunction. The loose part becomes involved in rotative motion mostly due to dry or fluid friction, and thus its motion is very erratic. The loose part can also move axially along the shaft. Detachment of the rotating part causes changes in the rotor balance state. Most often this results in higher unbalance. During steady-state operation the effect of a loose rotating part can manifest itself through heat vibration. It can be diagnosed by observing periodic changes of amplitude and phase of the synchronous response. During start-up (or shutdown) a loose rotating part carrying some amount of unbalance may manifest its dynamic action in the form of subsynchronous vibrations, very similar to those of other instabilities. The objective of this demonstration is to observe the effect of a loose rotating part (fixed, however, in the axial direction) under both steady-state (rotor constant speed) and transient (rotor start-up or shutdown) operation. The dynamic response depends very much on the amount of damping in the system: lubrication of the loose part/shaft surfaces and addition/elimination of aerodynamic drag blades, mounted on the loose disk, significantly change the rotor response.

  17. Opportunistic replacement of fusion power system parts

    International Nuclear Information System (INIS)

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

  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.

    2016-07-01

    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. PMID:26252760

  11. 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.

    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.

  13. 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.

    1978-01-01

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

    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.

  16. 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.

  17. 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.

  18. Manufacture of plastic parts by radiation molding

    International Nuclear Information System (INIS)

    Thin plastic parts which can have precise tolerances and can be of complex shape are prepared by casting a viscous radiation-curable composition onto a support, such as a moving web of polymeric material, in the shape of the desired part and then irradiating, for example with ultraviolet radiation or high energy electrons, to cause curing of the composition to a solid plastic. The radiation-curable composition is formulated with viscosity and flow characteristics it to be cast in the exact shape of the part desired yet retain this shape during curing while supported only by the surface on which it has been cast. Plastic parts made by this method can be formed entirely of the radiation-curable composition by casting onto a web having a release surface from which the part can be stripped subsequent to curing or can be formed partially from a web material and partially from the radiation-curable composition by casting onto a web to which the composition will bond and subsequently cutting the web into discrete portions which include the cured composition

  20. Automated Surface Inspection of Micro Parts

    Scholz-Reiter, Bernd; Thamer, Hendrik; Lütjen, Michael

    2010-10-01

    This chapter presents a machine vision system for detecting surface imperfections on micro parts. It is part of a quality control concept for micro production. Because of increasing product miniaturization, the mechanical manufacturing of micro components is becoming more and more important. The combination of high manufacturing rates and low tolerances in manufacturing processes enables the economical production of micro components. Due to the small component sizes and the difficulties associated with the handling process, the manual visual inspection retires as testing procedure. A customized surface inspection technology with an efficient image processing and classification system is needed. The objective of our concept is to identify surface imperfections such as raisings, laps and bulges on micro parts. The implementation of the system is explained by reference to a micro deep-drawn component, which is manufactured within the German Collaborative Research Center (CRC) 747.

    Successful pregnancy requires a state of immune homeostasis. Maternal tolerance of the genetically distinct fetoplacental unit is in part mediated by maternal and fetal pro- and anti-inflammatory cytokines; these cytokines have also been implicated in different pregnancy-related pathologic states. This two-part series seeks to provide anesthesiologists with an overview on selected perinatal cytokines in an effort to identify opportunities for research and improvements in clinical care. In part one, we review basic and pregnancy-related elements of the immune system, with an emphasis on the role of cytokines. From this foundation, we offer a perspective of a unique phenomenon witnessed within obstetric anesthesia - maternal temperature elevation associated with labor epidural analgesia. PMID:26970932

    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.

    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.

    2007-01-01

    Correct functioning of the entire stomatognathic system is achieved by a compatible relationship of all its parts. Four determinants, by their mutual harmonious activity, dictate the function of the entire system: the teeth, periodontium with supporting structure, muscles, temporomandibular joint (TMJ) and CNS. In such a complex system a disorder of any integrative part causes disturbances also in other parts of the system. Changed functions can arise through organic disorder, and also iatrogenically by inadequate conservative, prosthetic, surgical or orthodontic therapy. For this reason it is often difficult to recognise the primary cause. The first responses of the system to the disorder are adaptive mechanisms which occur within one or more integrative parts, and depending on their intensity and duration symptoms grow more prominent. Tissue response can be ortho- or parafunctional. Attempts are made to exclude psychoemotional influences and the obstacle eliminated by either abrasion, clenching or grinding of the teeth. If the obstacle is not eliminated by abrasion, the cause of such functional disorder becomes the trigger for parafunctional activity. From a review of the relevant literature it can be concluded that parafunctional activity is caused by changed occlusion, with determined psychological habits of the patient and specific tissue response of the stomatognathic system. Therefore, therapy of these disorders is made more difficult and includes a multidisciplinary approach. PMID:17912197

    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.

  15. Laser welding of micro plastic parts

    Science.gov (United States)

    Haberstroh, E.; Hoffmann, W.-M.

    2007-02-01

    Most welding processes for plastics do not meet the demands of micro technology and thus cannot be applied in this innovative industrial sector. One of the few techniques which are applicable in this sector is the laser transmission welding, which has distinctive advantages like low mechanical and thermal load of the joining parts. This makes the laser particularly suitable for the welding of micro plastics parts. Thereby, contour welding is a process variant of laser transmission welding enabling the welding of complex and even three-dimensional weld contours. But so far it has not yet been applied for welding plastics parts of micro scale in the industrial practice. Recent research at the Institute of Plastics Processing (IKV) at the RWTH Aachen University shows the feasibility of this process to weld small and complex micro parts. Good mechanical properties can be achieved. However, it is necessary to apply measures to reduce the formation of flash. Moreover, it can be shown that there is a strong influence of some material parameters on the laser welding process so that some plastics are more suitable than others for the contour welding in micro technology.

  17. Cryogenic Quenching Process for Electronic Part Screening

    Science.gov (United States)

    Sheldon, Douglas J.; Cressler, John

    2011-01-01

    The use of electronic parts at cryogenic temperatures (less than 100 C) for extreme environments is not well controlled or developed from a product quality and reliability point of view. This is in contrast to the very rigorous and well-documented procedures to qualify electronic parts for mission use in the 55 to 125 C temperature range. A similarly rigorous methodology for screening and evaluating electronic parts needs to be developed so that mission planners can expect the same level of high reliability performance for parts operated at cryogenic temperatures. A formal methodology for screening and qualifying electronic parts at cryogenic temperatures has been proposed. The methodology focuses on the base physics of failure of the devices at cryogenic temperatures. All electronic part reliability is based on the bathtub curve, high amounts of initial failures (infant mortals), a long period of normal use (random failures), and then an increasing number of failures (end of life). Unique to this is the development of custom screening procedures to eliminate early failures at cold temperatures. The ability to screen out defects will specifically impact reliability at cold temperatures. Cryogenic reliability is limited by electron trap creation in the oxide and defect sites at conductor interfaces. Non-uniform conduction processes due to process marginalities will be magnified at cryogenic temperatures. Carrier mobilities change by orders of magnitude at cryogenic temperatures, significantly enhancing the effects of electric field. Marginal contacts, impurities in oxides, and defects in conductor/conductor interfaces can all be magnified at low temperatures. The novelty is the use of an ultra-low temperature, short-duration quenching process for defect screening. The quenching process is designed to identify those defects that will precisely (and negatively) affect long-term, cryogenic part operation. This quenching process occurs at a temperature that is at least

  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.

  3. Modern NDT techniques applied to composite parts

    International Nuclear Information System (INIS)

    There are many Non Destructive Testing (NDT) techniques used on qualifying the composite made parts. a) Composite materials pose significant challenge for defect detection, since they are non-homogenous and anisotropic b) in nature. Throughout their life cycle composites are susceptible to the formation of many defects such as delamination, matrix cracking, fiber fracture, fiber pullout and impact damage. Various NDT methods are used for qualifying composite made parts like Ultrasonic, Radiographic, and Eddy Current etc. However, the latest techniques are Infra-Red Thermography, Neutron Radiography, Optical Holography, X-ray Computed Tomography and Acoustic Microscopy. This paper deals with each type of the methods and their suitability for different kinds of composites. (author)

    Science.gov (United States)

    Thomas, Kathy; Farrell, Mary Beth

    2015-03-01

    Clinical imaging protocols play an important role in the provision of high-quality care in nuclear medicine. It is imperative that all nuclear medicine facilities have protocols for every procedure performed. However, creating protocols that are detailed, unambiguous, and consistent is often easier said than done. Properly written protocols help to ensure that nuclear medicine procedures are performed in a standardized, reproducible manner so that patients receive high-quality care. This 2-part article provides technologists with a framework for composing comprehensive protocols. Part 1 discusses the secrets to successfully composing protocols ensuring they are detailed and step-by-step along with the importance of basing protocols on evidence from published guidelines and peer-reviewed literature. The components and important aspects of clinical imaging protocols are detailed. PMID:25613336

    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.

  7. How US utilities upgraded spare parts programmes

    International Nuclear Information System (INIS)

    Improvements in utility procurement practices during the past two years have mollified Nuclear Regulatory Commission (NRC) staff concerns about the potential for fraudulent or substandard spare parts making their way into nuclear power plants in the USA. Several cases of bogus parts being sold to utilities in the late 1980s had raised fears that a major problem existed with utilities' procurement programmes. But the cases highlighted the potential for fraud in the supply of replacement equipment for nuclear plants, and they put utilities under a spotlight. Today, the problem does not look as serious as it appeared at first. No new cases of fraud or misrepresented equipment have surfaced, and the NRC staff, impressed with a voluntary programme launched by the industry, now believes new regulations are unnecessary.

  8. 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.

  9. Fixed-film processes. Part 2

    International Nuclear Information System (INIS)

    Recently, full scale fixed-film or mixed suspended have been applied in many wastewater treatments plants.

    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.

    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.

    2006-08-01

    Full Text Available Purpose: Presentation of the possibilities of application of a new manufacturing method, called wedge rollsrolling (WRR in forming of axi – symmetrical hollowed parts.Design/methodology/approach: The research work was done in a specially designed laboratory rolling millLUW-2. During the research, hollowed parts from steel were rolled in hot forming conditions. Basic kinematicaland force parameters of the process were noticed during rolling.Findings: On the basis of the conducted research it was stated that the WRR method could be used for formingof hollowed parts with the precision compared with the precision obtained in the typical cross wedge rollingprocesses (CWR. At the same time, it was proved that this method could be used for rolling from billets withthe wall thinner than the wall given in the CWR.Research limitations/implications: The research were limited to the wedges with spreading angles withinrange of β = (5° ÷ 9°, with the constant values of forming angle α = 30° and relative reduction ratio δ = 1.45.In the future, it is planned to analyse the influence of changes of angle α and relative reduction ratio δ on theWRR process.Practical implications: The conducted research can be used for designing of a new industrial method of metalforming of hollowed parts.Originality/value: The innovation of this solution is based on the application of only one wedge for forming.Because of that, the WRR method is cheaper for implementation than used so far CWR processes. This methodcan be applied mainly in automotive and aviation industries.

    Sampling from a random discrete distribution induced by a `stick-breaking' process is considered. Under a moment condition, it is shown that the asymptotics of the sequence of occupancy numbers, and of the small-parts counts (singletons, doubletons, etc) can be read off from a limiting model involving a unit Poisson point process and a self-similar renewal process on the half-line.

    2000-11-01

    Osteoarthritis is the most common form of arthritis, affecting millions of people in the United States. It is a complex disease whose etiology bridges biomechanics and biochemistry. Evidence is growing for the role of systemic factors, such as genetics, diet, estrogen use, and bone density, and local biomechanical factors, such as muscle weakness, obesity, and joint laxity. These risk factors are particularly important in the weight-bearing joints, and modifying them may help prevent osteoarthritis-related pain and disability. Major advances in management to reduce pain and disability are yielding a panoply of available treatments ranging from nutriceuticals to chondrocyte transplantation, new oral anti-inflammatory medications, and health education. This article is part 2 of a two-part summary of a National Institutes of Health conference that brought together experts in osteoarthritis from diverse backgrounds and provided a multidisciplinary and comprehensive summary of recent advances in the prevention of osteoarthritis onset, progression, and disability. Part 2 focuses on treatment approaches; evidence for the efficacy of commonly used oral therapies is reviewed and information on alternative therapies, including nutriceuticals and acupuncture, is presented. Biomechanical interventions, such as exercise and bracing, and behavioral interventions directed toward enhancing self-management are reviewed. Current surgical approaches are described and probable future biotechnology-oriented approaches to treatment are suggested. PMID:11074906

    The rivers are in some circumstances part of the ground battlefield. Microseisms induced at the riverbed or ground at the river surrounding might be consequence of military activities (military ground transports, explosions, troop's activities, etc). Vibrations of those fluid-solid structures are modeled in terms of solid displacement and change of fluid pressure. This time varying fluid pressure in river, which originates from ground microseisms, is possible to detect with hydrophones. Therefore, hydroacoustic measurements in rivers enables detecting, identification and localization various types of military noisy activities at the ground as and those, which origin is in the river water (hydrodynamics of water flow, wind, waves, river vessels, etc). In this paper are presented river ambient noise measurements of the three great rivers: the Danube, the Sava and the Tisa, which flows in north part of Serbia in purpose to establish limits in detection of the ground vibrations in relatively wide frequency range from zero to 20 kHz. To confirm statement that the river is a part of ground battlefield, and that hydroacoustic noise is possible to use in detecting and analyzing ground microseisms induced by civil or military activities, some previous collected data of hydroacoustic noise measurement in the rivers are used. The data of the river ambient noise include noise induced by civil engineering activities, that ordinary take place in large cities, noise that produced ships and ambient noise of the river when human activities are significantly reduced. The poly spectral method was used in analysis such events.

  18. The metallurgy of superalloys part 2

    International Nuclear Information System (INIS)

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

  19. Manufacturing of GLARE Parts and Structures

    Science.gov (United States)

    Sinke, J.

    2003-07-01

    GLARE is a hybrid material consisting of alternating layers of metal sheets and composite layers, requiring special attention when manufacturing of parts and structures is concerned. On one hand the applicable manufacturing processes for GLARE are limited, on the other hand, due to the constituents and composition of the laminate, it offers new opportunities for production. One of the opportunities is the manufacture of very large skin panels by lay-up techniques. Lay-up techniques are common for full composites, but uncommon for metallic structures. Nevertheless, large GLARE skin panels are made by lay-up processes. In addition, the sequences of forming and laminating processes, that can be selected, offer manufacturing options that are not applicable to metals or full composites. With respect to conventional manufacturing processes, the possibilities for Fibre Metal Laminates in general, are limited. The limits are partly due to the different failure modes, partly due to the properties of the constituents in the laminate. For machining processes: the wear of the cutting tools during machining operations of GLARE stems from the abrasive nature of the glass fibres. For the forming processes: the limited formability, expressed by a small failure strain, is related to the glass fibres. However, although these manufacturing issues may restrict the use of manufacturing processes for FMLs, application of these laminates in aircraft is not hindered.

    2015-09-01

    Clinical preception in practice plays a significant role in both registered and practical nurse studies. As such, the cooperation between the faculty and working life is important to narrow the theory-practice gap, with emphasis being placed on a student-oriented approach promoting self-direction and lifelong learning. The aim of this project was to develop the preceptorship at five different units within the health-care sector in western Finland by implementing an action research (AR) approach. This article is the first of a two-part article on the project, focusing on a cultural analysis and the development of preception models conducted within the project. The five units participating in the study were the following: a long-term care ward in the community, a ward for people with dementia, a geriatric ward, a medical ward and a surgical ward representing specialised care. The starting point of the study was a cultural analysis, which was made in all the five units to obtain a 'bottom-up' perspective. In each of the five units 3-5 nurses were appointed to become members of the core groups. This meant that all the units would start from the perspective of their own working environment when creating a preception model that would fit into their particular workplace. During this process, the participants received continuous support from the researchers. Several workshops and seminars were also arranged to further support the core groups and staff. The models were implemented and tested during the academic year 2010-2011 followed by an evaluation of the project. The evaluation results will be presented in the second part of the two-part article. The project showed that reflective practice and critical thinking can be improved through an AR approach.

    2015-04-01

    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.

    In this process, a viscous radiation-curable composition is cast onto a support in the exact shape of the desired part and then irradiated, for example with ultraviolet radiation or high energy electrons, to cause curing of the composition, for example by polymerization and/or crosslinking. The support can be of a composition such that the cast material will bond to it or of a composition such that the cast material will not bond to it and can be stripped from the support after curing is effected

    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.

    The authors propose a new welding technique and machinery for the thermal contact welding thermoplastic parts of electric oil well pumps which efficiently creates welds of higher quality than those resulting from ultrasonic welding and also permits the use of cheaper and more readily available thermoplastics such as polyethylene and polypropylene which do not lend themselves to ultrasonic welding. The annual savings to the industry as a result of the implementation of their technique, and of the substitution of polypropylene for polyamide, amounts to 150,000 rubles.

  4. Integration-by-parts identities in FDR

    International Nuclear Information System (INIS)

    Four-Dimensionally Regularized/Renormalized (FDR) integrals play an increasingly important role in perturbative loop calculations. Thanks to them, loop computations can be performed directly in four dimensions and with no ultraviolet counterterms. In this paper I prove that integration-by-parts (IBP) identities based on simple integrand differentiation can be used to find relations among multi-loop FDR integrals. Since algorithms based on IBP are widely applied beyond one loop, this result represents a decisive step forward towards the use of the FDR approach in multi-loop calculations.

    In this paper, we introduce user prototypes as a technique that supports users’ articulation of emotions relevant for design: dreams, fears, motivations – their feelings and aspirations. Following Bateson’s writings about communication through art, we consider user prototypes as “partly unconscious...... communication” and propose to analyze them by focusing on the emotional articulations integrated in the users’ design language. We illustrate this with an example from a design research project on designing learning technology for young diabetics. The example shows how young people with diabetes can express...

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

    We have developed a practical scheme to construct partly occupied, maximally localized Wannier functions (WFs) for a wide range of systems. We explain and demonstrate how the inclusion of selected unoccupied states in the definition of the WFs can improve both their localization and symmetry...... properties. A systematic selection of the relevant unoccupied states is achieved by minimizing the spread of the resulting WFs. The method is applied to a silicon cluster, a copper crystal, and a Cu(100) surface with nitrogen adsorbed. In all cases we demonstrate the existence of a set of WFs...

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

    Four-Dimensionally Regularized/Renormalized (FDR) integrals play an increasingly important role in perturbative loop calculations. Thanks to them, loop computations can be performed directly in four dimensions and with no ultraviolet counterterms. In this paper I prove that integration-by-parts (IBP) identities based on simple integrand differentiation can be used to find relations among multi-loop FDR integrals. Since algorithms based on IBP are widely applied beyond one loop, this result represents a decisive step forward towards the use of the FDR approach in multi-loop calculations.

    An integral part of providing effective feedback to pharmacy residents occurs during the evaluation process. Residency evaluation involves measuring and documenting performance as it relates to standardized residency outcomes, goals, and learning objectives. Evaluations may be formative or summative and include the preceptor's evaluation of the resident's performance, the resident's self-assessments, and the resident's evaluation of the preceptor and learning experience. Evaluations are more structured than feedback, and they involve documentation of the verbal feedback that was provided throughout the learning experience. This article will focus on the preceptor's role in providing effective resident evaluations based on specific learning activities. PMID:24958969

    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.

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

    International Nuclear Information System (INIS)

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

    Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals - including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years. PMID:27176184

  12. The metallurgy of superalloys part 1

    International Nuclear Information System (INIS)

    This is part I of the report titled 'the metallurgy of superalloys'. In this part the structure, phases and systems of superalloys are reviewed. The role of alloying elements in the design of superalloys and the mechanical properties of superalloys are also reviewed. Superalloys are important in high temperature technology, especially above 700 degree c. They are 'super' mainly because their creep and stress rupture resistances are very high. Superalloys are based on an austenitic matrix including secondary phases, mainly gamma precipitates, inter and intragranular carbides mainly M23 C6 and M6 C. They are classified into three systems, Ni-base, Fe-Ni base and Ce-base alloys. Different alloying elements mainly Cr, Mo, Al, Ti are added to increase the strength either by solid solution hardening (Cr, Mo, Al), precipitation hardening (A 1, Ti to produce gamma) or by dispersion hardening (Cr, Mo to form M23 C6 and M6 C carbides) and to increase the oxidation resistance (Cr, Al). 3 tab., 2 fig

  13. Study of laser cladding nuclear valve parts

    International Nuclear Information System (INIS)

    The mechanism of laser cladding is discussed by using heat transfer model of laser cladding, heat conduction model of laser cladding and convective transfer mass model of laser melt-pool. Subsequently the laser cladding speed limit and the influence of laser cladding parameters on cladding layer structure is analyzed. A 5 kW with CO2 transverse flow is used in the research for cladding treatment of sealing surface of stop valve parts of nuclear power stations. The laser cladding layer is found to be 3.0 mm thick. The cladding surface is smooth and has no such defects as crack, gas pore, etc. A series of comparisons with plasma spurt welding and arc bead welding has been performed. The results show that there are higher grain grade and hardness, lower dilution and better performances of resistance to abrasion, wear and of anti-erosion in the laser cladding layer. The new technology of laser cladding can obviously improve the quality of nuclear valve parts. Consequently it is possible to lengthen the service life of nuclear valve and to raise the safety and reliability of the production system

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

    Cutaneous findings are not uncommonly a concomitant finding in patients afflicted with gastrointestinal (GI) diseases. The dermatologic manifestations may precede clinically evident GI disease. Part I of this 2-part CME review focuses on dermatologic findings as they relate to hereditary and nonhereditary polyposis disorders and paraneoplastic disorders. A number of hereditary GI disorders have an increased risk of colorectal carcinomas. These disorders include familial adenomatous polyposis, Peutz-Jeghers syndrome, and juvenile polyposis syndrome. Each disease has its own cutaneous signature that aids dermatologists in the early diagnosis and detection of hereditary GI malignancy. These disease processes are associated with particular gene mutations that can be used in screening and to guide additional genetic counseling. In addition, there is a group of hamartomatous syndromes, some of which are associated with phosphatase and tensin homolog (PTEN) gene mutations, which present with concurrent skin findings. These include Cowden syndrome, Bannayan-Riley-Ruvalcaba syndrome, and Cronkhite-Canada syndrome. Finally, paraneoplastic disorders are another subcategory of GI diseases associated with cutaneous manifestations, including malignant acanthosis nigricans, Leser-Trélat sign, tylosis, Plummer-Vinson syndrome, necrolytic migratory erythema, perianal extramammary Paget disease, carcinoid syndrome, paraneoplastic dermatomyositis, and paraneoplastic pemphigus. Each of these disease processes have been shown to be associated with an increased risk of GI malignancy. This underscores the important role of dermatologists in the diagnosis, detection, monitoring, and treatment of these disorders while consulting and interacting with their GI colleagues.

    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

    2001-09-01

    The article presents a retrospective history of the ALPHA series of publications. This action-research project (later called "cooperative research") on literacy and basic education is divided into three periods of seven years each. The first one, "Construction", involved assisting the nascent literacy movement in Québec and Canada by given it a theoretical, critical and ideological basis. In the second period, "Ruptures", the project distanced itself somewhat from the literacy movement, whose success, according to the author, was dubious. During the same period ALPHA systematised its critical function and internationalised its field of research. The third phase, "Wanderings", involved a different research paradigm, in which the project explored basic education at community level in connection with local development initiatives. This biographical/autobiographical account ends with the last publication ALPHA 2000, evincing an ecological vision for alternative education and sustainable communities, partly documented in the Arab countries.

  18. Stennis engineer part of LCROSS moon mission

    2009-01-01

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

  19. Essential Oils, Part IV: Contact Allergy.

    de Groot, Anton C; Schmidt, Erich

    2016-01-01

    Nearly 80 essential oils (including 2 jasmine absolutes) have caused contact allergy. Fifty-five of these have been tested in consecutive patients suspected of contact dermatitis, and nine (laurel, turpentine, orange, tea tree, citronella, ylang-ylang, sandalwood, clove, and costus root) showed greater than 2% positive patch test reactions. Relevance data are generally missing or inadequate. Most reactions are caused by application of pure oils or high-concentration products. The clinical picture depends on the responsible product. Occupational contact dermatitis may occur in professionals performing massages. The (possible) allergens in essential oils are discussed. Several test allergens are available, but patients should preferably be tested with their own products. Co-reactivity with other essential oils and the fragrance mix is frequent, which may partly be explained by common ingredients. Patch test concentrations for essential oils are suggested.

  20. Physics of badminton shuttlecocks. Part 1 : aerodynamics

    Cohen, Caroline; Darbois Texier, Baptiste; Quéré, David; Clanet, Christophe

    2011-11-01

    We study experimentally shuttlecocks dynamics. In this part we show that shuttlecock trajectory is highly different from classical parabola. When one takes into account the aerodynamic drag, the flight of the shuttlecock quickly curves downwards and almost reaches a vertical asymptote. We solve the equation of motion with gravity and drag at high Reynolds number and find an analytical expression of the reach. At high velocity, this reach does not depend on velocity anymore. Even if you develop your muscles you will not manage to launch the shuttlecock very far because of the ``aerodynamic wall.'' As a consequence you can predict the length of the field. We then discuss the extend of the aerodynamic wall to other projectiles like sports balls and its importance.

  1. Characteristic Aroma Compounds from Different Pineapple Parts

    Full Text Available Characteristic aroma volatile compounds from different parts of cayenne pineapple were analyzed by headspace-solid phase microextraction (HS-SPME and gas chromatography-mass spectrometry (GC/MS. The main volatile compounds were esters, terpenes, ketones and aldehydes. The number and content of aroma compounds detected in pulp were higher than those found in core. In pulp, the characteristic aroma compounds were ethyl 2-methylbutanoate, ethyl hexanoate, 2,5-dimethyl-4-hydroxy-3(2H-furanone (DMHF, decanal, ethyl 3-(methylthiopropionate, ethyl butanoate, and ethyl (E-3-hexenoate; while in core the main compounds were ethyl 2-methylbutanoate, ethyl hexanoate and DMHF. The highest odor units were found to correspond to ethyl 2-methylbutanoate, followed by ethyl hexanoate and DMHF. The odor units found for pulp were higher than those for core.

  2. Neurofibromatosis: part 2 – clinical management

    2015-06-01

    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.

    The first biosimilar version of a biologic agent used to treat psoriasis (infliximab) entered the Spanish market on February 16 of this year, and more biosimilars can be expected to follow in the coming months and years. Logically, this new situation will have economic repercussions and alter prescribing patterns among dermatologists. In this second part of the review, we will look at several somewhat contentious issues, such as the extrapolation of indications, interchangeability, and automatic substitution. We will also review the biosimilars with indications for psoriasis currently in the clinical development pipeline and assess their potential to offer comparable efficacy and safety to the reference product while contributing to the sustainability of the public health care system.

    2015-07-01

    The diffuse cystic lung diseases have a broad differential diagnosis. A wide variety of pathophysiological processes spanning the spectrum from airway obstruction to lung remodeling can lead to multifocal cyst development in the lung. Although lymphangioleiomyomatosis and pulmonary Langerhans cell histiocytosis are perhaps more frequently seen in the clinic, disorders such as Birt-Hogg-Dubé syndrome, lymphocytic interstitial pneumonia, follicular bronchiolitis, and light-chain deposition disease are increasingly being recognized. Obtaining an accurate diagnosis can be challenging, and management approaches are highly disease dependent. Unique imaging features, genetic tests, serum studies, and clinical features provide invaluable clues that help clinicians distinguish among the various etiologies, but biopsy is often required for definitive diagnosis. In part II of this review, we present an overview of the diffuse cystic lung diseases caused by lymphoproliferative disorders, genetic mutations, or aberrant lung development and provide an approach to aid in their diagnosis and management.

    The diffuse cystic lung diseases (DCLDs) are a group of pathophysiologically heterogenous processes that are characterized by the presence of multiple spherical or irregularly shaped, thin-walled, air-filled spaces within the pulmonary parenchyma. Although the mechanisms of cyst formation remain incompletely defined for all DCLDs, in most cases lung remodeling associated with inflammatory or infiltrative processes results in displacement, destruction, or replacement of alveolar septa, distal airways, and small vessels within the secondary lobules of the lung. The DCLDs can be broadly classified according to underlying etiology as those caused by low-grade or high-grade metastasizing neoplasms, polyclonal or monoclonal lymphoproliferative disorders, infections, interstitial lung diseases, smoking, and congenital or developmental defects. In the first of a two-part series, we present an overview of the cystic lung diseases caused by neoplasms, infections, smoking-related diseases, and interstitial lung diseases, with a focus on lymphangioleiomyomatosis and pulmonary Langerhans cell histiocytosis.

    2009-12-01

    Full Text Available El objetivo de este trabajo es discutir la importancia de los estudios de arqueología terrestre y subacuática como parte de un mismo proceso de interpretación del pasado. Se entiende que el registro arqueológico puede hallarse actualmente en una variedad de ambientes tanto terrestres como subacuáticos a causa de varias razones, como por ejemplo las oscilaciones de los niveles de agua ocurridas entre el Pleistoceno Final y el Holoceno Medio. Por lo tanto, se propone que para su recuperación debe utilizarse una metodología adaptada al medio ambiente en el cual se encuentre. En este sentido, es importante la interpretación integral del paisaje para acceder a la comprensión de la diversidad ambiental en la que se puede emplazar un sitio arqueológico, y en consecuencia poder “bucear” un registro integrado.

  7. Absorption chillers: Part of the solution

    International Nuclear Information System (INIS)

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

  10. 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.

  11. RA reactor operation in 1991, Part 1

    International Nuclear Information System (INIS)

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

  12. Computer hardware for radiologists: Part 2

    International Nuclear Information System (INIS)

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

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

    Scarlett, Nicola Vivienne Yorke; Tyson, Peter; Fraser, Darren; Mayo, Sheridan; Maksimenko, Anton

    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.

    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

  13. On-line alkali monitoring - Part 1

    International Nuclear Information System (INIS)

    As a consequence of the increased knowledge of the environmental impact of combustion based heat and power generation, the use of renewable biofuels will be increased. An obstacle associated to biofuel combustion compared to other fuels is the large release of alkali. Alkali compounds in flue gases are known to cause severe operational problems. Three of the major problems are; fouling of superheating tubes (causing reduced heat transfer and possibly corrosion), agglomeration of the bed material in fluidized beds, and poisoning of SCR catalysts. Yet another alkali related problem arises when, in order to increase the electric efficiency of combustion power plants, combined-cycle technology is used. Alkali vapour present in the fuel gas for the gas turbine is condensed to particles which increase corrosion and erosion of the turbine blades. The research on ash related operational problems has to be extended in order to ensure future use of biofuels in heat and power generation. In all successful research, adequate tools are necessary. To investigate ash related problems the key issue is to be able to perform continuous alkali measurements. This pilot study has investigated the need of continuous alkali measurements, which alkali species are harmful in the different applications and also available instrumentation capable of measuring the specific alkali species. The report gives a short summary presenting alkali related operational problems. In addition a schematic overview is given, showing the alkali species that possibly can exist in various parts of the power plant. 48 refs, 13 figs, 4 tabs

  14. Compressor Part II: Volute Flow Predictions

    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.

Siamo andati alla ricerca dei significati reconditi delle parole usate nei testi pubblicitari, e abbiamo scoperto, che dietro il tutto si muove una macchina organizzativa perfetta, che si serve di accurate ricerche motivazionali e si fa aiutare dalle scienze sociali per potere, sempre e in ogni caso, avere un potere di suggestione sul consumatore. La nostra ricerca ha voluto esaminare in che modo il mercato del biologico e del transgenico viene presentato al consumatore, quali tecniche pubblicitarie impiega e di che metodi persuasivi si avvale, ricordandoci sempre che la pubblicità, per sua stessa natura, sta dalla parte di chi 'produce' e non di chi 'consuma'.

    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%.

    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.

Assi, Spirocamallanus identifica os camalanídeos de cápsula bucal com lâminas espiraladas ou outras estruturas semelhantes, enquanto que Procamallanus se aplicaria aos de cápsula bucal lisa. Quanto às demais subdivisões existentes para o gênero, apoiadas em aspecto e quantidade de espículos, são consideradas resultado de um critério bastante arbitrário para conservarem-se válidas, visto serem os espículos caracteres sujeitos a diversas interpretações por parte dos especialistas, devido à fragilidade que os toma tão sujeitos a modificações no grupo dos camalanídeos. Três espécies são aqui tratadas: Procamallanus (Spirocamallanus rarus Travassos, Artigas & Pereira, 1928, Procamallanus (Spirocamallanus pimelodus, e Procamallanus (Spirocamallanus intermedius. As duas últimas são propostas como novas. Procamallanus (S. pimelodus é comparada a Procamallanus (Spirocamallanus olseni Campana-Rouget & Razahihelissoa, 1965, dela se distinguindo, principalmente, por apresentar o rebordo da asa caudal franjado e fortemente musculoso. Procamallanus (S. intermedius aproxima-se unicamente de Procamallanus (S. rarus, por apresentar o espículo maior com bifurcação distal e dela se afasta pelo maior número e menor espessura das lâminas espiraladas na cápsula bucal.

  4. Decontamination Process of Internal Part Pipes - 13442

    International Nuclear Information System (INIS)

    The Marcoule Site, created in 1955 is one of the first nuclear sites in France. It combines the activities of the Research Centre of the French Atomic Energy Commission (CEA) and AREVA industrial operations. Today, a large part of the operations on this site consists of the cleaning and the dismantling of nuclear Installations, once the end of their life cycle has been reached. An example can be the reprocessing plant UP1. This unit, started in 1958 has been stopped in 1997 and its dismantling started quickly thereafter. Technical challenges of the UP1 dismantling are mainly linked to a very high risk of exposure due to a large variety of contaminated equipments and residuals of fission products, potential sources of irradiation. The dismantling of Hall 71 is a typical example of such challenge. This paper will present a solution developed by AREVA Clean-Up business unit, in collaboration with COFIM Industry, to remove contamination incrusted inside the pipes before starting the cutting operations, thus reducing irradiation risk.

    Women are often under-represented in IT. And yet, at any age and whatever their level and background, it is a field that can arouse much interest.    To overcome this under-representation, the R0SEH1PSters community organises Django workshops targeted at women to introduce them to the world of coding and technology by teaching them how to successfully create a blog application and deploy it to the internet. And who knows, a spark of interest in the newly-discovered IT world may develop into a shine! The aim of Django Girls is also to increase the diversity within the industry. The mentors are mainly female volunteers who bring their passion to the workshop and are part of the awesome atmosphere attendees can feel during each event. Workshops have been organised worldwide regularly since 2014. Hosted by IdeaSquare and supported by the CERN IT department and the Diversity team, the Geneva workshop will take place in the evening on Friday evening, 26 February, and al...

  7. Bisphenol A in edible part of seafood

    Directory of Open Access Journals (Sweden)

    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.

  8. Compact tokamak reactors. Part 1 (analytic results)

    International Nuclear Information System (INIS)

    We discuss the possible use of tokamaks for thermonuclear power plants, in particular tokamaks with low aspect ratio and copper toroidal field coils. Three approaches are presented. First we review and summarize the existing literature. Second, using simple analytic estimates, the size of the smallest tokamak to produce an ignited plasma is derived. This steady state energy balance analysis is then extended to determine the smallest tokamak power plant, by including the power required to drive the toroidal field, and considering two extremes of plasma current drive efficiency. The analytic results will be augmented by a numerical calculation which permits arbitrary plasma current drive efficiency; the results of which will be presented in Part II. Third, a scaling from any given reference reactor design to a copper toroidal field coil device is discussed. Throughout the paper the importance of various restrictions is emphasized, in particular plasma current drive efficiency, plasma confinement, plasma safety factor, plasma elongation, plasma beta, neutron wall loading, blanket availability and recirculating electric power. We conclude that the latest published reactor studies, which show little advantage in using low aspect ratio unless remarkably high efficiency plasma current drive and low safety factor are combined, can be reproduced with the analytic model

  10. 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.

    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.

  15. [Medicine in ancient Mesopotamia - part 2].

    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.

    Objective:To investigate the role of Mdm2 expression in hepatocellular carcinoma.Methods: Streptavidin-peroxidase conjugation method (SP)was used to observe the expression of Mdm2 and p53 proteins in 61 cases of hepatocellular carcinoma(HCC)and 59 cases of corresponding paracancerous tissues,among which p53 mutations in exons 5~8 were detected in 21 cases by PCR-SSCP.Results:Positive nuclear P53 and Mdm2 immunostains were demonstrated in 57.38% and 26.23% of HCC,1.69% and 3.39% of corresponding paracancerous tissues respectively.The expression of p53 and Mdm2 proteins in hepatocellular carcinoma was significantly higher than that in paracancerous tissues(P<0.01).The expression of P53 and Mdm2 was not significantly correlated.42.86% of hepatocellualr carcinomas showed mutations in exon 7 of p53 gene,and no mutation was found in exons 5,6,8 and paracancerous tissues. 66.67% of mutational cases had P53 overexpression and 11.11%(1/9)showed overexpression of both P53 and Mdm2,Mdm2 overexpression also appeared in 25% of cases without mutations.Conclusions:Mdm2-induced p53 inactivation and p53 gene mutation play an important role in carcinogenesis of hepatocellular carcinoma.Tumorigenic property of Mdm2 itself,together with p53 mutation,may take part in hepatocarcinogenesis.

  17. Information as a part of radiation protection

    International Nuclear Information System (INIS)

    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

    Clinical preception in practice plays a significant role in the education of both Registered Nurses and practical nurses. This study presents the evaluation of an interprofessional research and development project (2009-2103) on clinical preceptorship between two universities of applied sciences, two vocational institutes and four healthcare organisations in western Finland. The research question was as follows: How did the participants evaluate the process and outcomes of developing preceptorship through an action-research approach? The primary target group consisted of professionals within the healthcare sector and nursing teachers at the universities of applied sciences and the vocational institutes. The five units represented in the healthcare organisations functioned as clinical practice placements for both nursing and practical nursing students, with Registered Nurses and practical nurses acting as their preceptors. Each unit developed a unique preceptorship model to answer their specific needs. The models were implemented and tested during one academic year followed by a quantitative (a 4-point scale) and qualitative evaluation of the process. The models are presented in another article, and the evaluation results are presented in this article. The evaluation showed that preceptorship has become an important and accepted part of work, including the practice of starting any preception at a unit with a thorough introduction. The project's emphasis on critical thinking, reflection and focus on ethics were valued by the staff. Pedagogical further education should be arranged on a regular basis to strengthen the knowledge base of the preceptors. Furthermore, enough time for preceptorship should be allocated, as it is a pedagogical duty. The implication of this project is that more cooperation between different stake holders is needed, in order to narrow the gap between theory and praxis. PMID:25833207

  1. Charged NUT field : [Part] I. Motion of test particles and [Part] II. Cosmic censorship

    International Nuclear Information System (INIS)

    Some properties of the charged NUT field are studied. In the first part of the paper, some general aspects of the charged NUT field have been investigated using uncharged and charged particles. The behaviour of the particles near the singularity has also been considered. In the second part of the paper, the charged NUT sources in the context of cosmic censorship hypothesis are studied. Motion of charged particles in the equatorial plane and along the axis is considered. From this investigation the interesting result is discovered that by such a bombardment of charged test particles, the existing event horizons cannot be destroyed but, in contrast to the Reissner-Nordstrom field, naked singularities do not get enveloped by event horizons.

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

    Directory of Open Access Journals (Sweden)

    Qi Zhu

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

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

  7. Radioactivity survey data in Japan, part 2

    International Nuclear Information System (INIS)

    The publication is aimed at providing radioactivity survey data in environmental and dietary materials in Japan. Part 2 gives dietary materials, consisting of total diet, rice, milk, vegetables, sea fish, freshwater fish, shellfish, and seaweeds. Samples were collected from 37 sampling locations during the period between August 1988 and March 1989, and were sent to the Japan Chemical Analysis Center for radiochemical analysis. Strontium-90 and cesium-137 in these dietary materials are tabulated. The maximum concentrations of strontium-90 and cesium-137 were as follows: 0.12±0.012 Bq/p·d and 0.16±0.012 Bq/p·d, respectively, for total diet; 0.0000±0.0084 Bq/Kgwet and 0.42±0.019 Bq/Kgwet for rice (producing districts); 0.0000±0.0084 Bq/Kgwet and 0.048±0.0091 Bq/Kgwet for rice (consuming districts); 0.059±0.008 Bq/l and 0.26±0.013 Bq/l for milk (producing districts for domestic program); 0.14±0.013 Bq/l and 0.19±0.011 Bq/l for milk (producing districts for WHO program); 0.057±0.008 Bq/l and 0.15±0.010 Bq/l for milk (consuming districts); 0.97±0.032 Bq/Kgwet and 0.062±0.010 Bq/Kgwet for vegetables (producing districts); 0.52±0.024 Bq/Kgwet and 0.051±0.009 Bq/Kgwet for vegetables (consuming districts); 0.043±0.010 Bq/Kgwet and 0.34±0.017 Bq/Kgwet for sea fish; 0.96±0.032 Bq/Kgwet and 0.066±0.009 Bq/Kgwet for freshwater fish; 0.017±0.019 Bq/Kgwet and 0.027±0.011 Bq/Kgwet for shellfish; and 0.031±0.011 Bq/Kgwet and 0.12±0.10 Bq/Kgwet for seaweeds. Yearly changes in the concentrations of both strontium-90 and cesium-137 from 1985 through 1989 are given in figures. (N.K.)

    As a matter of good business practices, a team of glovebox experts from Los Alamos National Laboratory (LANL) has been assembled to proactively investigate processes and procedures that minimize unplanned breaches in the glovebox, e.g., glove failures. A major part of this effort involves the review of glovebox glove failures that have occurred at the Plutonium Facility and at the Chemical and Metallurgy Research Facility. Information dating back to 1993 has been compiled from formal records. This data has been combined with information obtained from a baseline inventory of about 9,000 glovebox gloves. The key attributes tracked include those related to location, the glovebox glove, type and location of breaches, the worker, and the consequences resulting from breaches. This glovebox glove failure analysis yielded results in the areas of the ease of collecting this type of data, the causes of most glove failures that have occurred, the effectiveness of current controls, and recommendations to improve hazard control systems. As expected, a significant number of breaches involve high-risk operations such as grinding, hammering, using sharps (especially screwdrivers), and assembling equipment. Surprisingly, tasks such as the movement of equipment and material between gloveboxes and the opening of cans are also major contributions of breaches. Almost half the gloves fail within a year of their install date. The greatest consequence for over 90% of glovebox glove failures is alpha contamination of protective clothing. Personnel self-monitoring at the gloveboxes continues to be the most effective way of detecting glovebox glove failures. Glove failures from these tasks can be reduced through changes in procedures and the design of remote-handling apparatus. The Nuclear Materials Technology Division management uses this information to improve hazard control systems to reduce the number of unplanned breaches in the glovebox further. As a result, excursions of contaminants

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

    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.

    2007-01-01

    In communication, information, and other industries, three-part tariffs are increasingly popular. A three-part tariff is defined by an access price, an allowance, and a marginal price for any usage in excess of the allowance. Empirical nonlinear pricing studies have focused on consumer choice under two-part tariffs. We show that consumer behavior differs under three-part tariffs and assess how consumer demand uncertainty impacts tariff choice. We develop a discrete/continuous model of choice ...

  19. Engineering BioBrick vectors from BioBrick parts

    Directory of Open Access Journals (Sweden)

    Knight Thomas F

    2008-04-01

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