Generation of equipment response spectrum considering equipment-structure interaction

International Nuclear Information System (INIS)

Lee, Sang Hoon; Yoo, Kwang Hoon

2005-01-01

Floor response spectra for dynamic response of subsystem such as equipment, or piping in nuclear power plant are usually generated without considering dynamic interaction between main structure and subsystem. Since the dynamic structural response generally has the narrow-banded shapes, the resulting floor response spectra developed for various locations in the structure usually have high spectral peak amplitudes in the narrow frequency bands corresponding to the natural frequencies of the structural system. The application of such spectra for design of subsystems often leads to excessive design conservatisms, especially when the equipment frequency and structure are at resonance condition. Thus, in order to provide a rational and realistic design input for dynamic analysis and design of equipment, dynamic equipment-structure interaction (ESI) should be considered in developing equipment response spectrum which is particularly important for equipment at the resonance condition. Many analytical methods have been proposed in the past for developing equipment response spectra considering ESI. However, most of these methods have not been adapted to the practical applications because of either the complexities or the lack of rigorousness of the methods. At one hand, mass ratio among the equipment and structure was used as an important parameter to obtain equipment response spectra. Similarly, Tseng has also proposed the analytical method for developing equipment response spectra using mass ratio in the frequency domain. This method is analytically rigorous and can be easily validated. It is based on the dynamic substructuring method as applied to the dynamic soil-structure interaction (SSI) analysis, and can relatively easily be implemented for practical applications without to change the current dynamic analysis and design practice for subsystems. The equipment response spectra derived in this study are also based on Tseng's proposed method

Cleaves, J.E.; Fletcher, W.M.

1993-01-01

A three-dimensional (3-D) computer model of the Advanced Neutron Source (ANS) main control complex is being developed. The main control complex includes the main control room, the technical support center, the materials irradiation control room, computer equipment rooms, communications equipment rooms, cable-spreading rooms, and some support offices and breakroom facilities. The model will be used to provide facility designers and operations personnel with capabilities for fit-up/interference analysis, visual ''walk-throughs'' for optimizing maintain-ability, and human factors and operability analyses. It will be used to determine performance design characteristics, to generate construction drawings, and to integrate control room layout, equipment mounting, grounding equipment, electrical cabling, and utility services into ANS building designs. This paper describes the development of the initial phase of the 3-D computer model for the ANS main control complex and plans for its development and use

The Fermilab Main Ring control system has been operational for over sixteen years. Aging and obsolescence of the equipment make the maintenance difficult. Since the advent of the Tevatron, considerable upgrades have been made to the controls of all the Fermilab accelerators except the Main Ring. Modernization of the equipment and standardization of the hardware and software have thus become inevitable. The Tevatron CAMAC serial system has been chosen as a basic foundation in order to make the Main Ring control system compatible with the rest of the accelerator complex. New hardware pieces including intelligent CAMAC modules have been designed to satisfy unique requirements. Fiber optic cable and repeaters have been installed in order to accommodate new channel requirements onto the already saturated communication medium system. 8 refs., 2 figs

Shotcrete is widely used in architecture, hydraulic engineering structures, finishing works in tunnels, arc covers and ceilings. The problem of the equipment choice in shotcreting is very important. The main issues influencing the equipment choice are quality improvement and intensification of shotcreting. Main parameters and rational limits of technological characteristic of machines used in solving different problems in shotcreting are described. It is suggested to take into account peculiarities of shotcrete mixing processes and peculiarities of applying these mixtures with compressed air kinetic energy. The described method suggests choosing a mixer with the account of energy capacity, Reynolds number and rotational frequency of the mixing drum. The suggested choice procedure of the equipment nomenclature allows decreasing exploitation costs, increasing the quality of shotcrete and shotcreting in general.

ABSTRACT Objectives There aren’t any objective methods that may help in standard evaluation of oral surgery patient’s psycho-emotional status. Without any standardized evaluation, two main problems appear: heterogeneity between studies and ineffective patient’s evaluation. Therefore, Universal Scale in Oral Surgery (USOS) for patient’s psycho-emotional status rating has previously been proposed by authors. The aim of present study is to assess the clinical effectivity and validate the Universal Scale in Oral Surgery in case of outpatient tooth extraction for adult healthy patients. Material and Methods Clinical trial to validate the USOS for patient’s psycho-emotional status rating was performed. In total 90 patients, that came for outpatient dental extraction to Lithuanian University of Health Sciences Oral and Maxillofacial Surgery Department ambulatory, were enrolled in clinical trial. Patients filled self-reported questionnaires before the procedure. Operating surgeon rated USOS for patient’s psycho-emotional status rating doctor’s part questionnaire after the procedure. 4 - 6 weeks later all patients were asked to fill USOS for patient’s psycho-emotional status rating questionnaire retrospectively. Results According to the statistical analysis, the final composition of USOS for patient’s psycho-emotional status rating that would fit to reliability coefficient should be composed from 6 patient part questions and 3 general doctor part questions. Conclusions Universal Scale in Oral Surgery for patient’s psycho-emotional status rating is a novel, doctor and patient rated scale which is suitable for clinical and scientific usage. PMID:29435204

Full Text Available We study a queuing system which is equipped with a stand-by server in addition to the main server. The stand-by server provides service to customers only during the period of absence of the main server when either the main server is on a vacation or it is in the state of repairs due to a sudden failure from time to time. The service times, vacation times, and repair times are assumed to follow general arbitrary distributions while the stand-by service times follow exponential distribution. Supplementary variables technique has been used to obtain steady state results in explicit and closed form in terms of the probability generating functions for the number of customers in the queue, the average number of customers, and the average waiting time in the queue while the MathCad software has been used to illustrate the numerical results in this work.

Full Text Available Con el fin de obtener un diagnóstico del estado actual de conocimiento sobre usos de las palmas en la Amazonia colombiana, se revisaron las principales fuentes de información. Treinta y seis de las 41 etnias indígenas consideradas tuvieron registros de uso. Se registraron 82 especies de palmas usadas (78% de las potenciales y 165 usos distribuidos en ocho categorías; todos los usos se presentan de manera detallada en un catálogo. Las categorías de uso más importantes fueron: utensilios y herramientas, construcción, y alimentación humana. Las diez especies más importantes fueron Bactris gasipaes, Euterpe precatoria, Mauritia flexuosa, Oenocarpus bataua, Attalea maripa, Oenocarpus minor, Astrocaryum chambira, Iriartea deltoidea, Oenocarpus bacaba y Socratea exorrhiza; la mayoría de ellas también han sido registradas como las más importantes en otras partes del Neotrópico. No se encontró ninguna información sobre usos de palmas para varios grupos indígenas, especialmente para las etnias cocama, letuama, piaroa, pisamira y yurí, para las cuales se requieren investigaciones detalladas. Se concluye que a pesar de los vacíos de información, los resultados muestran que las palmas son un recurso muy importante con un gran potencial, y una pieza fundamental para la seguridad alimentaria y el desarrollo sustentable de la Amazonia colombiana. Sugerimos la inclusión de las especies más importantes en programas de manejo y agroforestales, al igual que la implementación y popularización de técnicas de cosecha no destructivas. Recomendamos además que las investigaciones futuras estén enfocadas en desarrollar estrategias de manejo que garanticen el uso sostenible de todas estas especies útiles.

The electric equipment maintenance strategies are changing from PM(Preventive Maintenance) or CM(Corrective Maintenance) to CBM(Condition Based Maintenance). The main benefits of CBM are reduced possibility of service failures of critical equipment and reduced costs or maintenance work. In CBM, the equipment status need to be monitored continuously and a decision should be made whether an equipment need to be repaired or replaced. For the maintenance decision making, the CBR(Case Base Reasoning) system is introduced. The CBR system receives the current equipment status and retrieves the case based historic database to determine any possible equipment failure under current conditions. In retrieving the case based historic data, the suggested DSS(Decision Support System) uses a reasoning engine with an equipment/asset ontology that describes the equipment subsumption relationships

The main features of electrical stimulation of biological tissues by implant electrodes are studied.These electrodes are applied in neural prostheses and cardiac pacing.Threshold phenomena are stressed and some aspects related with implant electrode design are discussed. A fairly through theoretical research about the optimal pulse shape for electrical stimulation of biological tissues is done.The excitation functional is introduced as a criterium to identify threshold pulses of electric current. We obtain the optimal pulse shapes that minimize the energy dissipated in tissues, or the energy taken by the load seen by the pulse generator, amongst other criteria.We show how these pulse shapes can be determined from experimentally measured strength-duration (S-D) curves using rectangular pulses of current. The development of a prototype of a new equipment is described.The equipment may be used to measure S-D curves and with this information it is able to syntetize the abovementioned optimal pulse shapes. The top-down design process is presented, involving both hardware and software.The construction and assembling of the prototype, as well as the implementation of software are described.Some testing and measures with the prototype, including test with biological tissues are described and assessed

ONKALO - Main drawings in 2007

International Nuclear Information System (INIS)

2008-05-01

The first overall site characterisation programme for a Finnish repository of spent nuclear fuel was introduced in 1982. This programme already suggested that the site confirmation for a detailed repository design and safety assessment should include characterisation performed in an underground rock characterisation facility (URCF). This idea was confirmed during the detailed site characterisation. International views have also emphasised the importance of underground characterisation before the final decision to construct the repository is taken. The underground rock characterisation facility (ONKALO) is excavated at Olkiluoto in the municipality of Eurajoki. ONKALO should be constructed to allow characterisation work for site confirmation without jeopardising long-term safety of the repository site. It should also be possible to link ONKALO later to the repository as to a part of it. The construction of ONKALO was started in 2004 and will be completed in 2014. The characterisation work has started in ONKALO and will focus on the disposal depth. In the main drawings stage, ONKALO was described at the level of detail needed for a construction permit in 2003. This meant description of the location, final structures and final systems. This summary report describes the development of design to updated main drawings in 2007 at the same level of detail (no temporary arrangements are described). The main changes are the added exhaust air shaft and advancing the controlled area's inlet air shaft to the ONKALO phase. Also the layout and the depth of the characterisation levels have been updated according to the current bedrock information. Some buildings on the surface will house sets of equipment directly connected with underground facility and this equipment is described in this report. No buildings or other equipment are described in this report, because they are not directly connected with the underground facility. The main element of ONKALO is a system of

The gas plant at Kaarstoe was built as part of the Statpipe gas transport system and went on stream in 1985. In 1993 another line was routed from the Sleipner field to carry condensate, and the plant was extended accordingly. Today heavy additional supply- and export lines are under construction, and the plant is extended more than ever. The main role of the factory is to separate the raw gas into commercial products and to pump or ship it to the markets. The site covers a large number of well-known mechanical equipment. This presentation deals with piping, mechanical and structural disciplines. The lifetime of mechanical equipment is often difficult to predict as it depends on many factors, and the subject is complex. Mechanical equipment has been kept in-house, which provides detailed knowledge of the stages from a new to a 14 years old plant. The production regularity has always been very high, as required. The standard of the equipment is well kept, support systems are efficient, and human improvisation is extremely valuable.

2017-01-01

Full Text Available The issues of purification of secondary waters of industrial production have an important place and are relevant in the environmental activities of all food and chemical industries. For cleaning the transporter-washing water of beet-sugar production the key role is played by the equipment of treatment plants. A wide variety of wastewater treatment equipment is classified according to various methods. Typical structures used are sedimentation tanks, hydrocyclones, separators, centrifuges. In turn, they have a different degree of purification, productivity through the incoming suspension and purified secondary water. This is equipment is divided into designs, depending on the range of particles to be removed. A general classification of methods for cleaning the transporter-washing water, as well as the corresponding equipment, is made. Based on the analysis of processes and instrumentation, the main methods of wastewater treatment are identified: mechanical, physicochemical, combined, biological and disinfection. To increase the degree of purification and reduce technical and economic costs, a combined method is widely used. The main task of the site for cleaning the transporter-washing waters of sugar beet production is to provide the enterprise with water in the required quantity and quality, with economical use of water resources, taking into account the absence of pollution of surface and groundwater by industrial wastewater. In the sugar industry is currently new types of washing equipment of foreign production are widely used, which require high quality and a large amount of purified transporter-washing water for normal operation. The proposed classification makes it possible to carry out a comparative technical and economic analysis when choosing the methods and equipment for recuperation of secondary waters. The main equipment secondary water recovery used at the beet-sugar plant is considered. The most common beet processing plant is a

Full Text Available Este artículo presenta los resultados de un estudio sobre la utilización que hacen los jóvenes andaluces de las redes sociales. Los objetivos fundamentales son: conocer los usos preferentes de las redes sociales, su frecuencia y los motivos que les impulsan a su utilización. Además se estudia si existen diferencias de sexo tanto en la frecuencia como en las motivaciones de uso. Se aplica un cuestionario para la recogida de datos. La muestra es de 1.487 adolescentes de Andalucía. Los resultados muestran que los jóvenes en su mayoría usan de manera habitual las redes sociales y se identifican dos vertientes motivacionales en su uso: una social y otra psicológica. No se hallan diferencias significativas entre sexos en cuanto a frecuencia de uso, pero sí en las motivaciones para su acceso. Las de los chicos son de tipo emocional, mientras que en las chicas predomina la motivación de carácter relacional. Los resultados obtenidos muestran coincidencias con investigaciones internacionales realizadas en contextos muy diferentes al presente estudio. En la discusión de resultados se plantean futuras líneas de trabajo, a la vez que se identifican implicaciones que los usos de las redes sociales tienen para la formación e integración social de una ciudadanía activa y participativa, así como para el enriquecimiento de dimensiones como el desarrollo del capital social y la educación.

Optimization of the replacement period of plant equipment is one of the main items to rationalize the activities on plant maintenance. There are several models to replace the equipment and the formulations for optimizing the replacement period are different among these models. In this study, we calculated the optimum replacement periods for some equipment parts based on the replacement models and found that the optimum solutions are not so largely differ from the replacement models as far as the replacement period is not so large. So we will be able to use the most usable model especially in the early phase of rationalization on plant maintenance, since there are large uncertainties in data for optimization. (author)

The remote handling (RH) tools and equipment development in ITER focuses mainly on the welding and cutting technique, weld inspection and double-seal door which are essential factors in the replacement of in-vessel components such as divertor and blanket. The conceptual design of these RH tools and equipment has been defined through ITER engineering design activity (EDA). Similarly, elementary R and D of the RH tools and equipment have been extensively performed to accumulate a technological data base for process and performance qualification. Based on this data, fabrications of full-scale RH tools and equipment are under progress. A prototypical bore tool for pipe welding and cutting has already been fabricated and is currently undergoing integrated performance tests. This paper describes the design outline of the RH tools and equipment related to in-vessel components maintenance, and highlights the current status of RH tools and equipment development by the Japan Home Team as an ITER R and D program. This paper also includes an outline of insulation joint and quick-pipe connector development, which has also been conducted through the ITER R and D program in order to standardize RH operations and components.

Equipment specifications for an electrochemical fuel reprocessing plant

International Nuclear Information System (INIS)

Hemphill, Kevin P.

2010-01-01

Electrochemical reprocessing is a technique used to chemically separate and dissolve the components of spent nuclear fuel, in order to produce new metal fuel. There are several different variations to electrochemical reprocessing. These variations are accounted for by both the production of different types of spent nuclear fuel, as well as different states and organizations doing research in the field. For this electrochemical reprocessing plant, the spent fuel will be in the metallurgical form, a product of fast breeder reactors, which are used in many nuclear power plants. The equipment line for this process is divided into two main categories, the fuel refining equipment and the fuel fabrication equipment. The fuel refining equipment is responsible for separating out the plutonium and uranium together, while getting rid of the minor transuranic elements and fission products. The fuel fabrication equipment will then convert this plutonium and uranium mixture into readily usable metal fuel.

Este trabalho investiga a percepção de estudantes sobre o uso de um laboratório virtual como recurso de ensino e aprendizagem. Esse ambiente virtual permite a manipulação de elementos de circuito e aparelhos medidores. Além desse recurso, outros sete recursos foram concebidos para serem usados de maneira coordenada, de modo a mediar a ação dos estudantes, bem como as interações estudante-estudante e estudantes-professor, os quais têm como foco o ensino e a aprendizagem do conhecimento escolar sobre circuitos elétricos. Neste artigo, são discutidos os conceitos de mediação, ação mediada e recursos mediacionais, bem como uma interpretação teórica, elaborada a posteriori, das escolhas que nos levaram a conceber e a coordenar os recursos que utilizamos. A avaliação da pertinência de nossas expectativas, em relação às contribuições do uso de ambientes virtuais pelos estudantes levou-nos às seguintes questões: (a como se compara o engajamento declarado pelos estudantes no uso do laboratório virtual simulador de circuitos, com o engajamento declarado por esses sujeitos no uso dos outros recursos mediacionais?; (b para os estudantes, o uso do laboratório virtual contribuiu para a realização das ações de ensino e aprendizagem mediadas pelos outros recursos? Os dados que construímos para responder a essas questões foram produzidos a partir de um questionário de avaliação do curso e de autoavaliação respondido pelos estudantes ao final de um trimestre letivo. Os resultados encontrados mostram um alto engajamento discente no uso dos recursos mediacionais e sua percepção acerca da importância do ambiente virtual para a realização das ações mediadas pelos outros recursos.

O uso do celular por estudantes na escola: motivos e desdobramentos

Full Text Available Resumo: A sociedade contemporânea vivencia a era da conexão, mobilidade e ubiquidade na comunicação humana, desencadeando novas formas de interação e colaboração em redes e ambientes on-line. Neste contexto, há uma disseminação crescente e acelerada do uso de aparelhos móveis, e inevitavelmente esse uso começa a ocorrer com mais frequência na escola. O objetivo desta pesquisa foi compreender os motivos e desdobramentos do uso dos aparelhos celulares pelos estudantes na escola. A metodologia utilizada foi a Teoria Fundamentada (Glaser; Strauss, 1999 e os dados foram obtidos por meio de interações no Twitter, questionário e entrevistas on-line com estudantes que estivessem acessando a internet na escola por meio de um aparelho móvel. Com base nos dados coletados, foram elaboradas quatro categorias explanatórias do uso do celular na escola por estudantes: regras, uso didático, motivação e consequências. A partir da análise dos dados, nota-se que, em geral, as escolas tendem a proibir o uso, contudo, os estudantes costumam transgredir, utilizando seus celulares em virtude do tempo livre na escola ou do tédio nas aulas. Além disso, relata-se o uso com a finalidade de acesso às redes sociais, de distração e de pesquisa de conteúdo relacionado às disciplinas. Neste cenário, indica-se que a escola compreenda as questões sociais e culturais relativas à cibercultura dos jovens e perceba o fenômeno como uma oportunidade de aproximação e aprendizagem mútua.

2013-06-01

Full Text Available O contexto do uso de drogas aparece desafiador para a saúde pública brasileira. Ao relacioná-lo com a população de travestis, faz-se necessário uma sistematização singular, pela vulnerabilidade característica desse segmento. Considerando o trabalho desenvolvido num serviço de saúde específico para travestis no Estado de Minas Gerais, foi desenvolvida uma pesquisa que teve por objetivo identificar e quantificar o uso e abuso de drogas pelas travestis, profissionais do sexo que frequentam o serviço oferecido. A metodologia é fundamentada em uma pesquisa de levantamento de dados dos prontuários das pacientes e o uso apoiador do caderno de campo. Foram utilizados 59 prontuários analisados por um instrumento de coleta que identificou: características demográficas da amostra, uso de drogas, tipos de drogas utilizadas, frequência de uso. O instrumento de coleta foi revertido para um banco de dados digitalizado que projetou as estatísticas. Como resultado, ressaltou-se um uso significativo para álcool e outras drogas entre essa população, bem como os tipos mais comuns e suas frequências. A análise dos dados prevê uma dissonância entre critérios diagnósticos da síndrome da dependência química e a autoidentificação das travestis sobre a própria saúde, relacionando o uso ao contexto de vida. Os desdobramentos desses resultados imprimem a necessidade de maiores levantamentos pela relação marcante entre abuso de substância, transmissão do HIV/Aids, de outras DSTs, bem como de situações de violência e da permanência desse segmento na marginalidade.

Full Text Available O trabalho tem por objetivo apresentar os usos finais de eletricidade e rotinas de uso em habitações de interesse social. Os dados foram obtidos por meio de auditoria energética em uma amostra de 60 habitações de interesse social da região de Florianópolis-SC, por meio de aplicação de questionários aos moradores e medições do consumo de energia elétrica. Os dados obtidos com os questionários se referem à situação socioeconômica dos moradores e às rotinas de uso dos equipamentos eletroeletrônicos e iluminação, estimados para períodos de verão e inverno. As medições foram utilizadas para a caracterização dos equipamentos e lâmpadas, determinação do consumo de energia elétrica e o tempo de uso, por um período maior do que duas semanas em cada habitação. O tratamento de dados foi feito em forma de intervalos de confiança, por meio de métodos estatísticos paramétricos e não paramétricos. Os resultados mostraram que o chuveiro elétrico representa o maior uso final da amostra, com 36,8% de mediana, seguido dos refrigeradores, televisão e iluminação. Os dados não mostraram diferenças significativas entre os períodos de verão e inverno, devido ao tamanho reduzido da amostra e à variabilidade dos dados. As rotinas de uso encontradas, quando associadas à densidade potência média respectiva, são variáveis de entrada para estudos de simulação computacional do desempenho térmico dessas habitações, além de ajudarem na caracterização desse tipo de edificação. A correta quantificação dos usos finais de eletricidade de amostras pequenas leva à adoção de medidas corretas e específicas para a eficiência energética dessas habitações.

Qualification of Electrical Equipment in Nuclear Power Plants - Management of ageing

International Nuclear Information System (INIS)

Spaang, Kjell; Staahl, Gunnar

2013-02-01

The purpose of this report is to describe programs and tools for assessment of accomplished and documented qualification with respect to ageing of electrical equipment and for development of complimentary ageing management programs. In addition to description of complete programs for management of ageing, tools for validation of the status with regard to ageing of installed ('old') equipment and, where needed, for complementation of their qualification are also included. The report is restricted to safety related equipment containing ageing sensitive parts, mainly organic materials. To this category belong cables and cable joints and a number of equipment containing oils, seals (o-rings), etc. For equipment located in the containment, the possibilities of continuous supervision are limited. The accessibility for regular inspections is also limited in many cases. The main part of this report deals with the qualification of such equipment. Some safety related equipment outside the containment can be located in areas where they are subjected to high temperature and other excessive environmental stresses during normal operation and in areas affected by an accident. Therefore, some material is given also on qualification of equipment located outside containment with better possibilities for frequent inspection and supervision. Part 1 of the report is an executive summary with a general review of the methodologies and their application. The more detailed description of the programs and underlying material, useful data, etc. is given in Part 2

Effectiveness of medical equipment donations to improve health systems: how much medical equipment is broken in the developing world?

Science.gov (United States)

Perry, Lora; Malkin, Robert

2011-07-01

It is often said that most of the medical equipment in the developing world is broken with estimates ranging up to 96% out of service. But there is little documented evidence to support these statements. We wanted to quantify the amount of medical equipment that was out of service in resource poor health settings and identify possible causes. Inventory reports were analyzed from 1986 to 2010, from hospitals in sixteen countries across four continents. The UN Human Development Index was used to determine which countries should be considered developing nations. Non-medical hospital equipment was excluded. This study examined 112,040 pieces of equipment. An average of 38.3% (42,925, range across countries: 0.83-47%) in developing countries was out of service. The three main causes were lack of training, health technology management, and infrastructure. We hope that the findings will help biomedical engineers with their efforts toward effective designs for the developing world and NGO's with efforts to design effective healthcare interventions.

This research was conducted in support of two branches of the EPA ENERGY STAR program, whose overall goal is to reduce, through voluntary market-based means, the amount of carbon dioxide emitted in the U.S. The primary objective was to collect data for the ENERGY STAR Office Equipment program on the after-hours power state of computers, monitors, printers, copiers, scanners, fax machines, and multi-function devices. We also collected data for the ENERGY STAR Commercial Buildings branch on the types and amounts of ''miscellaneous'' plug-load equipment, a significant and growing end use that is not usually accounted for by building energy managers. This data set is the first of its kind that we know of, and is an important first step in characterizing miscellaneous plug loads in commercial buildings. The main purpose of this study is to supplement and update previous data we collected on the extent to which electronic office equipment is turned off or automatically enters a low power state when not in active use. In addition, it provides data on numbers and types of office equipment, and helps identify trends in office equipment usage patterns. These data improve our estimates of typical unit energy consumption and savings for each equipment type, and enables the ENERGY STAR Office Equipment program to focus future effort on products with the highest energy savings potential. This study expands our previous sample of office buildings in California and Washington DC to include education and health care facilities, and buildings in other states. We report data from twelve commercial buildings in California, Georgia, and Pennsylvania: two health care buildings, two large offices (> 500 employees each), three medium offices (50-500 employees), four education buildings, and one ''small office'' that is actually an aggregate of five small businesses. Two buildings are in the San Francisco Bay area of California, five are in

Todos los trabajadores están expuestos a una serie de riesgos, la mayor parte de ellos prevenibles de forma colectiva, pero en algunas ocasiones, estas medidas no llegan a ser del todo eficaces por lo que son necesarios equipos de protección individual. Estos equipos están destinados a ser llevados o sujetados por los trabajadores para protegerles de los riesgos que puedan amenazar su seguridad o su salud en el ámbito del trabajo, pero sin embargo, son capaces por sí mismos de crear efectos indeseables en la salud de los trabajadores, derivados de su uso. Por este motivo, los médicos del trabajo deben vigilar la salud de los trabajadores, valorando sus factores personales que puedan dificultar el uso de EPIs, informar y formar a los trabajadores sobre todo lo relativo al uso de los mismos, elegir el EPI adecuado para cada trabajador y, sobretodo, realizar un seguimiento para detectar posibles efectos indeseables del uso de EPIs y así evitar la no utilización y, por tanto, la ineficacia del EPI.In this study will provide information on personal protective equipment (PPE as an important part of our work as doctors work.

Full Text Available Resumen Objetivo: Este estudio pretende explorar como los campesinos no usuarios de plaguicidas difieren en su conocimiento, actitudes y creencias y percepciones de control y confianza en torno al uso de plaguicidas comparado con usuarios de plaguicidas. Metodología: Colectamos 79 cuestionarios con hombres y mujeres adultas que son campesinos agricultores en San Cristóbal, Antioquia, Colombia. Examinamos las percepciones de estos campesinos sobre el daño de los plaguicidas sobre la salud humana y el medio ambiente. También se exploraron sus creencias, actitudes, percepciones de control y confianza relacionadas con el uso de los plaguicidas. Resultados: Los hallazgos difieren entre los dos grupos de campesinos muestreados: usuarios y no usuarios de plaguicidas. Los usuarios de pesticidas experimentaron menores percepciones del daño de los plaguicidas sobre la salud humana y el medio ambiente, menor percepción del control acerca de parar el uso de plaguicidas (el incremento de una unidad en control disminuyó el logit de usar pesticidas en un 74%, y menor confianza acerca de parar el uso de pesticidas comparado con los no usuarios de plaguicidas (el aumento de una unidad en la confianza, disminuyó el logit de usar pesticidas en un 64%. Discusión: Varios factores individuales influencian la salud ocupacional y la salud de los campesinos incluyendo la percepción del control y la confianza. Recomendamos que futuras intervenciones educativas en salud pública aumenten el entrenamiento sobre prácticas seguras y la confianza. Así los campesinos pueden ganar control en el proceso de implementar cambios en su comportamiento relacionado con la reducción del uso de pesticidas.

On justification of efficient Energy-Force parameters of Hydraulic-excavator main mechanisms

Science.gov (United States)

Komissarov, Anatoliy; Lagunova, Yuliya; Shestakov, Viktor; Lukashuk, Olga

2018-03-01

The article formulates requirements for energy-efficient designs of the operational equipment of a hydraulic excavator (its boom, stick and bucket) and defines, for a mechanism of that equipment, a new term “performance characteristic”. The drives of main rotation mechanisms of the equipment are realized by hydraulic actuators (hydraulic cylinders) and transmission (leverage) mechanisms, with the actuators (the cylinders themselves, their pistons and piston rods) also acting as links of the leverage. Those drives are characterized by the complexity of translating mechanical-energy parameters of the actuators into energy parameters of the driven links (a boom, a stick and a bucket). Relations between those parameters depend as much on the types of mechanical characteristics of the hydraulic actuators as on the types of structural schematics of the transmission mechanisms. To assess how energy-force parameters of the driven links change when a typical operation is performed, it was proposed to calculate performance characteristics of the main mechanisms as represented by a set of values of transfer functions, i.e. by functional dependences between driven links and driving links (actuators). Another term “ideal performance characteristic” of a mechanism was introduced. Based on operation-emulating models for the main mechanisms of hydraulic excavators, analytical expressions were derived to calculate kinematic and force transfer functions of the main mechanisms.

The computerized radiographic application in the industrial area is a recent event. The imaging plate is the equipment used as imaging receiver during the exposition radiographic technique, which consists of a flexible photostimulable phosphor screen, capable of storing the photons energy of the incident X and γ rays and of a reading unit which uses a laser device to stimulate a visible light. As two types of phosphor screen are manufactured, one for general use (General Plate - GP) and another one for specific using (High Resolution-HR), one of the objectives of this study was to evaluate the spatial resolution capability in both plates using the Kodak equipment. Furthermore, equipment from different makers, Kodak and General Electric Company - GE, were compared. Two phosphor screen HR were used as the main objective of this study. Imaging Quality Indicators - IQI were used to evaluate the spatial resolution of the images in accordance with ASME and DIN standard. The results show that after evaluating the GP and HR Kodak plates, the HR plate was capable of showing a larger resolution of details. However, after evaluating the performance of the HR Kodak plate and GE plate, over the same acquisition condition and with the same size of the laser focal set of 87 μm, the results show a superiority in the GE equipment used for industrial radiographic, mainly for processed images in each specific ambient of digital processing and its performance in meeting satisfactorily the ASME code and the DIN standard.

This Process integrates and coordinates a broad range of equipment reliability activities into one process, performed by the Plant in a non-centralized way. The integration and coordination of these activities will allow plant personnel to evaluate the trends of important station equipment, develop and implement long-term equipment health plans, monitor equipment performance and condition, and make adjustments to preventive maintenance tasks and frequencies based on equipment operating experience, if necessary, arbitrating operational and design improvements, to reach a Failure-free Operation. This paper describes the methodology of Equipment Reliability Improvement Process, being focused on main aspects of the implementation process, relating to the scope and establishment of an Equipment Reliability Monitoring Plan, which should include and complement the existing mechanisms and organizations in the Plant to monitor the condition and performance of the equipments, with the common aim of achieving an operation free of failures. The paper will describe the tools that Iberdrola Ingenieria has developed to support the implementation and monitoring of the Equipment Reliability Improvement Process, as well as the results and lessons learned from its implementation in Almaraz NPP and Trillo NPP.

Common floor system vertical earthquake-proof structure for reactor equipment

International Nuclear Information System (INIS)

Morishita, Masaki.

1996-01-01

In an LMFBR type reactor, a reactor container, a recycling pump and a heat exchanger are disposed on a common floor. Vertical earthquake-proof devices which can be stretched only in vertical direction formed by laminating large-sized bellevilles are disposed on a concrete wall at the circumference of each of reactor equipments. A common floor is placed on all of the vertical earthquake-proof devices to support the entire earthquake-proof structure simultaneously. If each of reactor equipments is loaded on the common floor and the common floor is entirely supported against earthquakes altogether, since the movement of each of the reactor equipments loaded on the common floor is identical, relative dislocation is not exerted on the main pipelines which connect the equipments. In addition, since the entire earthquake structure has a flat common floor and each of the reactor equipments is suspended to minimize the distance between a gravitational center and a support point, locking vibration is less caused to the horizontal earthquake.

Recently there has been an intensive development of intelligent industrial equipment that is highly automated and can be rapidly adjusted for certain details. This equipment can be robotics systems, automatic wrappers and markers, CNC machines and 3D printers. The work equipment considered is the system for selective curing of photopolymers using a UV-laser and UV-radiation in such equipment that leads to additional technical difficulties. In many cases for transporting the radiation from the laser to the point processed, a multi-mirror system is used: however, such systems are usually difficult to adjust. Additionally, such multi-mirror systems are usually used as a part of the equipment for laser cutting of metals using high-power IR-lasers. For the UV-lasers, using many mirrors leads to crucial radiation losses because of many reflections. Therefore, during the development of the optical system for technological equipment using UV-laser we need to solve two main problems: to transfer the radiation for the working point with minimum losses and to include the system for controlling/handling the radiation spot position. We introduce a system for working with UV-lasers with 450mW of power and a wavelength of 0.45 μm based on a fiber system. In our modelling and design, we achieve spot sizes of about 300 μm, and the designed optical and mechanical systems (prototypes) were manufactured and assembled. In this paper, we present the layout of the technological unit, the results of the theoretical modelling of some parts of the system and some experimental results.

Trace or ultratrace analyses require that the HPLC equipment used, including the detector, be optimal for such determinations. HPLC detectors are discussed at length in Chapter 4; discussion here is limited to the rest of the equipment. In general, commercial equipment is adequate for trace analysis; however, as the authors approach ultratrace analysis, it becomes very important to examine the equipment thoroughly and optimize it, where possible. For this reason they will review the equipment commonly used in HPLC and discuss the optimization steps. Detectability in HPLC is influenced by two factors (1): (a) baseline noise or other interferences that lead to errors in assigning the baseline absorbance; (b) peak width. 87 refs

1994-01-01

This paper presents a generic equipment access software package for a distributed control system using computers with UNIX or UNIX-like operating systems. The package consists of three main components, an application Equipment Access Library, Message Handler and Equipment Data Base. An application task, which may run in any computer in the network, sends requests to access equipment through Equipment Library calls. The basic request is in the form Equipment-Action-Data and is routed via a remote procedure call to the computer to which the given equipment is connected. In this computer the request is received by the Message Handler. According to the type of the equipment connection, the Message Handler either passes the request to the specific process software in the same computer or forwards it to a lower level network of equipment controllers using MIL1553B, GPIB, RS232 or BITBUS communication. The answer is then returned to the calling application. Descriptive information required for request routing and processing is stored in the real-time Equipment Data Base. The package has been written to be portable and is currently available on DEC Ultrix, LynxOS, HPUX, XENIX, OS-9 and Apollo domain. ((orig.))

Nuclear power station main control room habitability

International Nuclear Information System (INIS)

Paschal, W.B.; Knous, W.S.

1989-01-01

The main control room at a nuclear power station must remain habitable during a variety of plant conditions and postulated events. The control room habitability requirement and the function of the heating, ventilating, air-conditioning, and air treatment system are to control environmental factors, such as temperature, pressure, humidity, radiation, and toxic gas. Habitability requirements provide for the safety of personnel and enable operation of equipment required to function in the main control room. Habitability as an issue has been gaining prominence with the Advisor Committee of Reactor Safeguards and the Nuclear Regulatory Commission since the incident at Three Mile Island. Their concern is the ability of the presently installed habitability systems to control the main control room environment after an accident. This paper discusses main control room HVAC systems; the concern, requirements, and results of NRC surveys and notices; and an approach to control room habitability reviews

2016-01-01

Full Text Available La literatura contable ha destacado que el uso interactivo de los sistemas de control de gestión genera en los empleados comportamientos proactivos que influyen positivamente en su rendimiento. Sin embargo, los procesos a través de los cuales este uso interactivo influye en el comportamiento de los individuos siguen sin estar identificados. Parte de este vacío en la literatura se puede explicar porque se ha tratado el uso interactivo como un concepto unidimensional. En el presente trabajo se distinguen 5 dimensiones del uso interactivo y se aísla el efecto de una de ellas sobre el comportamiento de los individuos. Analizamos un modelo de mediación que relaciona el uso interactivo con el rendimiento. Las hipótesis del trabajo se analizan con un experimento realizado con 84 estudiantes. Los resultados demuestran que el uso interactivo provoca respuestas emocionales positivas en los individuos, lo que determina cambios en su comportamiento e incide positivamente en su rendimiento

Full Text Available A partir de entrevistas en profundidad, realizadas en un hogar de la tercera edad en Ciudad del Cabo (Sudáfrica, este estudio analiza los principales usos y gratificaciones que reciben las personas mayores en interacción con los ordenadores. En África, mientras el énfasis investigador se ha puesto en los últimos años en la salud de los mayores, especialmente en cuanto al SIDA, existe muy poca investigación sobre el uso de los mayores en cuanto a nuevas tecnologías, ya que la investigación en relación con las mismas se ha centrado principalmente en la juventud. En este estudio se halló que los participantes utilizan el correo electrónico y las redes sociales para mantener el contacto con familiares y amigos y a veces incluso con su vecindario. Además, mantener el contacto suponía no solo comunicación, sino también observación de actividades, como noticias, fotografías y conversaciones. En el contexto de los usos y gratificaciones, el trabajo ha evidenciado que los participantes se sentían conectados con la sociedad, tanto por su comunicación como por la observación de las personas, y por mantenerse informados de las noticias y los temas de interés actuales. Mediante el uso de Internet, las personas de edad avanzada se comunicaban mucho más de lo que antes se habían comunicado con otras personas. Algunos de los participantes se sentían menos aislados y solos, debido a su uso del ordenador. Sin embargo, se demostró también que el uso de los ordenadores no obstaculizó los contactos interpersonales tradicionales.

To analyze the motives for using and not using pedestrian bridges (PB. MATERIAL AND METHODS. A cross-sectional survey was conducted of a sample of pedestrian users and non-users of PB; a logistic regression model was used to analyze the motives for use and non-use. RESULTS. The prevalence of non-use was 50.5 % of 813 surveyed pedestrians; the principal reason to use a PB was safety, and not to use it was "laziness". There were significant differences when analyzing the reason of non-use in the age groups 19 to 36 years, adjusted for education and physical characteristics of the PB ([aOR=1.7; 95 % CI=1.06-2.86] and [ORa.1.9; 95 % CI=1.14-3.33], respectively. CONCLUSIONS. The results of this study allow us to identify important aspects to consider "from the perspective of the pedestrians" when constructing new PB and improving existing PB to increase use in areas with a high risk of pedestrian injuries.

Welding technologies for nuclear machinery and equipment

International Nuclear Information System (INIS)

Kobayashi, Masahiro; Yokono, Tomomi.

1991-01-01

The main welding methods applied to nuclear machinery and equipment are shielded metal arc welding, submerged arc welding, MAG welding and TIG welding. But in the last 10 years, in order to improve the reliability required for the welding of nuclear machinery and equipment, the welding technologies aiming at the reduction of heat input, the decrease of the number of welding pass and the automatic control of welding factors have been applied for the main purpose of bettering the quality and excluding human errors. The merits and the technology of narrow gap, pulsed MAG welding and melt-through welding are explained. As the automation of TIG welding, image processing type narrow gap, hot wire TIG welding and remote control type automatic TIG welding are described. For the longitudinal welding of active metal sheet products, plasma key-hole welding is applied. Since the concentration of its arc is good, high speed welding with low heat input can be done. For the stainless steel cladding by welding, electroslag welding has become to be employed in place of conventional submerged arc welding. Arc is not generated in the electroslag welding, and the penetration into base metal is small. (K.I.)

Space Heating Equipment

Energy Technology Data Exchange (ETDEWEB)

Rafferty, Kevin D.

1998-01-01

The performance evaluation of space heating equipment for a geothermal application is generally considered from either of two perspectives: (a) selecting equipment for installation in new construction, or (b) evaluating the performance and retrofit requirements of an existing system. With regard to new construction, the procedure is relatively straightforward. Once the heating requirements are determined, the process need only involve the selection of appropriately sized hot water heating equipment based on the available water temperature. It is important to remember that space heating equipment for geothermal applications is the same equipment used in non-geothermal applications. What makes geothermal applications unique is that the equipment is generally applied at temperatures and flow rates that depart significantly from traditional heating system design. This chapter presents general considerations for the performance of heating equipment at non-standard temperature and flow conditions, retrofit of existing systems, and aspects of domestic hot water heating.

A ORACLE-based system for data collection, storage and analysis of main equipment load factors in NPPs and TPPs

International Nuclear Information System (INIS)

Ivanova, L.

1993-01-01

This data base is developed by the National Electricity Company, Sofia (BG) as an aid to supervision, analysis and administration decision making in a variety of operational situations in NPPs and TPPs. As major indicators of the equipment condition the following primary data are stored: steam or electricity production per month; operation hours per month; equipment stand-by outages; planned outages; unplanned permitted maintenance outages; unplanned emergency maintenance outages; number of outages of the unit per month. These data cover the period from the putting of the corresponding equipment into operation till the present moment, i.e. or about 32 years. The data up to 1990 are annual and for the last three years - monthly. Based on these primary data, the following quantities are calculated: average capacity; average load factors; operation time factors - total and accounting for the planned and the permitted unplanned outages; unpermitted outages factors - total and accounting for the planned and the permitted outages. All the factors are calculated on user's request for a chosen time period, by summing up correspondingly the major indicators (production, operation hours and various outages) for the given period. The system operates on an IBM 4341 under VM/SP and DB ORACLE V.5. The input is entered directly from the TPP and NPP by telex lines from PCs, operating also as telex machines, into the mainframe of Energokibernetika Ltd. They are available to all authorised users from local terminals or PCs, connected to the computer by synchronous or asynchronous lines. A system for data transmission to remote users along commutated telephone lines is also developed. (R. Ts.)

Full Text Available The author considers in detail the stages of creating a testing procedure for mining equipment based on the complex implementation of principles of nondestructive testing and technical diagnostics. The author substantiates effectiveness of application of a complex diagnostic approach for assessing the state of metal structures and energy-mechanical equipment of mining machines. The opportunity for timely detection of defects, regardless of their type and degree of danger, presents itself only with a wide application of the modern methods of vibration diagnostics and nondestructive testing. The author substantiates the effectiveness of specific combination of methods of nondestructive testing, most optimally suited for solving given tasks. The article contains the developed complex of more than 120 diagnostic rules, suitable for performing automated analysis of vibroacoustic signal and revealing the main damages of energy-mechanical equipment based on selective groups of informative frequencies. The author formulates the main criteria that one can use as a basic platform for improving the methodology for normalizing the parameters of mechanical oscillations. The developed diagnostic criteria became a basis for the development of individual spectral masks suitable for performing the analysis of parameters of vibroacoustic waves generated during operation of mining equipment. The author proves necessity of transition of repair and maintenance divisions of industrial enterprises to the system of maintenance of machinery according to its actual technical state, and the developed complex of diagnostic rules for detecting defects can serve as a platform for the implementation of basic elements of this system. The author substantiates the principal validity of the developed methodology for testing mining machines equipment and its individual elements, such as the predictive modeling of degradation of technical state of mining equipment and the

Safety measures for the main control board replacement project at Ikata units 1 and 2

International Nuclear Information System (INIS)

Hashimoto, Nozomu; Tada, Kenji

2013-01-01

When Units 1 and 2 of the Ikata Power Station underwent replacement of their main control boards, control cabinets, and associated equipment, it was necessary to remove all the control boards, cabinets, and cables from the control building including from the main control room. This meant the loss of operation and monitoring functions in the main control room and functions of control cabinets. To maintain the operation and monitoring functions required under plant shutdown conditions, temporary operation and monitoring equipment (i.e., temporary main control board) was installed in the temporary main control room. The advance preparations included a trial switching from the permanent to the temporary main control board to identify and address potential problems in advance. When the replacement work was underway, a work schedule sheet posted in the temporary and the permanent control rooms was used to prevent human errors caused by operators’ recognition errors. Monitoring and control signals were switched from the old boards to the temporary boards and from the temporary boards to the new boards at appropriate timings to ensure plant safety during the replacement operation.

Baltimore Gas and Electric's pilot project using the live insertion method to replace a cast iron main provided excellent results. Its use on Eastern Avenue, a major state highway, was cost effective, provided gas service to customers during the work, required relatively short construction time and resulted in only minor traffic disruptions. Gas service transfers to the new main were done at customer convenience and resulted in outages of only a few hours per customer. This paper reports that the project involved inserting a 6-in. plastic line inside an existing 10-in. cast iron main. Miller Pipeline Corp., Indianapolis, supplier of the Insertec left-angle R right-angle live insertion method was contracted for the job. Miller technicians assisted BG and E forces by providing a load analysis of the main, a pushing machine and related supplies, foaming equipment and pipe cutting tools. Company forces were responsible for all preparatory work, including opening all excavations, installing bypasses, and fusing and testing the plastic pipe. Service transfers and renewals were also completed by company employees

With the rapid development of technology and society, all walks of life in China are becoming more and more dependent on power systems. When earthquake occurs, the electrical equipment of substation is prone to damage because of its own structural features, top-heavy, and brittleness of main body. At the same time, due to the complex coupling of the soft electrical connection of substation electrical equipment, the negative impact can not be estimated. In this paper, the finite element model of the coupling system of the single unit of high voltage electrical equipment with the connecting soft bus is established and the seismic response is analysed. The results showed that there is a significant difference between the simple analysis for the seismic response of electrical equipment monomer and the analytical results of electrical equipment systems, and the impact on different electrical equipment is different. It lays a foundation for the future development of seismic performance analysis of extra high voltage electrical equipment.

1. Natural vibration frequencies are main characteristics of buildings and structures which allow to give integral estimation of their in-service state. Even relatively small changes of these frequencies as compared to the initially registered values point to serious defects of building structures. In this paper we analyzed natural vibration frequencies and natural modes of the main building (MB) of Novovoronezhskaya NPP operating nuclear unit with WWER-440 type reactor. The MB consists of a reactor compartment (RC), a machine room (MR) and an electric device (ED) unit positioned in between. 2. Natural vibration frequencies and natural modes of the MB were determined experimentally by analyzing its microvibrations caused by operation of basic equipment (turbines, pumps, etc.). Microvibrations of the main building were measured at 12 points. At each point measurements were carried out along two or three mutually perpendicular vibration directions. Spectral analysis of vibration records has been conducted. Identification of natural vibration frequencies was carried out on the basis of the spectral peaks and plotted vibration modes (taking into account operating frequencies of the basic equipment of the power generating unit). On the basis of the measurement results three transverse modes and corresponding natural vibration frequencies of the MB, one longitudinal mode and corresponding natural vibration frequency of the MB and two natural frequencies of vertical vibrations of RC and MR floor trusses (1st and 2nd symmetric forms) were determined. Dynamic characteristics of the main building of NV NPP resulting from full scale researches are supposed to be used as one of building structure stability criteria. (authors)

Full Text Available A preliminary prototype of a brachytherapy equipment has been constructed. The work started by developing conceptual design, followed by basic design and detailed design. In the conceptual design, design requirements are stated. In the basic design, technical specifications for main components are determined. In detailed design, general drawings are discussed. The prototype consists of three main systems: a mechanical system, an instrumentation system, and a safety system. The mechanical system assures the movement mechanism of the isotope source position beginning from the standby position until the applicators. It consists of three main modules: a position handling module, a container module, and a channel distribution module. The position handling module serves to move the isotope source position. As shielding, the second module is to store the source when the equipment is in standby position. The prototype provides 12 output channels. The channel selection is performed by the third module. The instrumentation system controls the movement of source position by handling motor operations. It consists of several modules. A microcontroller module serves as a control center whose task includes both controlling motors and communicating with computer. A motor module serves to handle motors. 10 sensors, including their signal conditionings, are introduced to read the environment conditions of the equipment. LEDs are used to display these conditions. In order to facilitate the operators’ duty, communication via RS232 is provided. The brachytherapy equipment can therefore be operated by using computer. Interface software is developed using C# language. To complete both mechanical and instrumentation systems performance, a safety system is developed to make sure that the safety for operator and patients from receiving excessive radiation. An interlock system is introduced to guard against abnormal conditions. In the worst case, a manual intervention

Ageing of insulation and diagnosis of electrical equipment through detection of partial discharge

International Nuclear Information System (INIS)

Lopez Vergara, T.; Velasco Bernal, C.

1994-01-01

Ageing in electrical equipment affects mainly its insulation system. Such ageing in the insulation system is determined by its organic nature, basically constituted by three families of materials: cellulose, resin and hydrocarbon. All of these are affected by high temperatures, which tend to produce a break in the molecular chains (if the temperatures are not too high) or carbonization and gasification of the material (if they are). The radiation absorbed by the insulating materials also destroys molecular chains, causing degradation of the material. The break of the molecular chains, especially in the polymer-based materials, fragments the material, mainly in areas subjected to mechanical forces and stresses. From the electrical point of view, fissures occurring the insulating material lead to a much lower dielectric strength in certain parts of the materials, which could produce partial discharge conditions. Therefore, the growth of partial discharges in electrical equipment items is frequently the consequences of ageing, and be used to evaluate their residual life. Empresarios Agrupados has developed a system to detect partial discharges which can be used while equipment is still in operation. The measurements taken with this system are sufficiently accurate and repetitive to be used in evaluating the condition of medium-voltage electrical equipment insulation. (Author)

Renewal of radiological equipment.

Science.gov (United States)

2014-10-01

In this century, medical imaging is at the heart of medical practice. Besides providing fast and accurate diagnosis, advances in radiology equipment offer new and previously non-existing options for treatment guidance with quite low morbidity, resulting in the improvement of health outcomes and quality of life for the patients. Although rapid technological development created new medical imaging modalities and methods, the same progress speed resulted in accelerated technical and functional obsolescence of the same medical imaging equipment, consequently creating a need for renewal. Older equipment has a high risk of failures and breakdowns, which might cause delays in diagnosis and treatment of the patient, and safety problems both for the patient and the medical staff. The European Society of Radiology is promoting the use of up-to-date equipment, especially in the context of the EuroSafe Imaging Campaign, as the use of up-to-date equipment will improve quality and safety in medical imaging. Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or renewal. This plan should look forward a minimum of 5 years, with annual updates. Teaching points • Radiological equipment has a definite life cycle span, resulting in unavoidable breakdown and decrease or loss of image quality which renders equipment useless after a certain time period.• Equipment older than 10 years is no longer state-of-the art equipment and replacement is essential. Operating costs of older equipment will be high when compared with new equipment, and sometimes maintenance will be impossible if no spare parts are available.• Older equipment has a high risk of failure and breakdown, causing delays in diagnosis and treatment of the patient and safety problems both for the patient and the medical staff.• Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or replacement.

Full text: The provision of effective, reliable, and user-friendly equipment needed for the implementation of safeguards is one of the main objectives of the Division of Technical Services (SOTS) in the Department of Safeguards. As an outcome of a review by an independent external consultant firm, the instrumentation sections of the SGTS were reorganized in January 2001 into two new sections, the Section for NDA Systems and Seals (TNS) and Section for Installed Systems (TIE). Each section has 'cradle-to-grave' responsibilities for development, implementation, maintenance, and decommissioning of safeguards instruments and measurement systems. Unattended assay, monitoring and surveillance instruments are the responsibility of TIE while attended nondestructive assay (NDA) instruments and seals are handled by TNS. The principal goals of both sections are to define equipment requirements based on Departmental needs, to coordinate Support Programme tasks concerning development and implementation activities, to provide system engineering of commercial components, manage laboratory and to do field testing and prove system suitability for defined safeguards applications. In addition both sections coordinate equipment and supply needs for the Department, including acquisition, preparation, servicing, installation, commissioning, troubleshooting, maintenance and repair, ensuring their availability when needed. As required, TIE and TNS provide specialized field support to the Operations Divisions. Each section is working to standardize equipment as much as possible and reduce the number of instruments performing the same function. This reduces both inspector and technician training, required parts inventories, and overall life-cycle costs. Development based on User Needs from the Operations Divisions follows a strict quality control program that includes a thorough qualification testing procedure with the last phase being field-testing under actual facility conditions.

Full Text Available A demodicose ou sarna demodécica é uma dermatoparasitose não contagiosa e ocasionada por uma reação cutânea inflamatória relacionada à multiplicação excessiva do ácaro Demodex canis. As causas da doença não estão totalmente definidas, entretanto, a baixa imunidade é um fator que predispõe a doença. A classificação da demodicose baseia-se na localização corpórea do animal, sendo localizada ou generalizada. O prognóstico é variável. Os sinais clínicos são alopecia, eritema, descamação, hiperpigmentação, liquenificação, febre e linfoadenopatia. O diagnóstico é realizado através de raspado cutâneo, impressão em fita de acetato, tricograma ou biópsia de pele. O tratamento há décadas foi realizado através do uso do amitraz, porém, além da toxicidade, o uso inadequado desse fármaco ocasionou em desenvolvimento de resistência. Atualmente, as lactonas macrocíclicas, tais como ivermectina, doramectina, milbemicina oxima e moxidectina vêm sendo empregadas com sucesso em cães. Entretanto, cães das raças dolicocéfalas, tais como Collie e Pastor Alemão, dentre outras, manifestam reações tóxicas graves com o uso da ivermectina. Assim, o objetivo desse trabalho foi relatar um caso do uso da doramectina na dose de 0,6 mg/kg, via oral a cada 72 horas, durante 60 dias no tratamento da demodicose generalizada em um cão da raça Pastor Alemão. Os resultados obtidos demostraram a melhora clínica do animal e nenhum efeito adverso foi clinicamente observado. Concluindo, não obstante a demodicose ser uma doença clínica desafiadora, o uso da doramectina demostrou vantagens pelo maior intervalo de administração, redução na duração do tratamento e a ausência de reações adversas, comuns as avermectinas quando usadas em animais dolicocéfalos.

This paper describes thermal cutting equipment. Thermal cutting equipment is classified into gas, plasma and laser cutting equipment. Based on the level of automation, the gas cutting equipment has been developed in the order of manual, automatic, eye-tracer, and NC cutters. For recent eye-tracer, paper pattern is inputted in a computer and repeatedly traced. For NC cutting equipment, automatic gas flow rate setting device and sensor for tracing nozzle height are installed. Oxygen plasma cutter is used for cutting soft steel materials. Simplified systems with current below 100 A are mainly used. High-speed cutting is conducted by NC control. Problems of life-time of electrode tips, load of workers, cutting performance, and penetration at corners have been solved. For laser cutter, NC control is also adopted. Since there are no short life-time consumables and conditions can be automatically set, the laser cutter has been put into practice as unmanned equipment. Problems of cutting speed and processing speed have been solved. Gas cutting with multi-blowpipes and unmanned operation of laser cutting are most useful for reducing the cost. 2 figs., 3 tabs.

Full Text Available This paper proposes to articulate an analytical scheme for understanding the use of drugs in advanced societies from the gender perspective and its intersections with other inequality axis such as age, social class, race and ethnicity. These dimensions define not only the access to different substances –in terms of normative and resources- but also the different uses and their social valuation. For this purpose, we expose the main gender dimensions as an analytical category: structural, symbolic and individual. Furthermore, we intend to broaden this view exploring the intra-inter gender differences and inequalities present in the various uses of drugs from an intersectional framework. Our aim is to break with standardised categories in order to project a multidimensional analysis, from which to reflect in how other imbricated differences with gender make possible for women and men to use certain substances, conditioning their social effects.Este trabajo propone articular un esquema analítico para la comprensión de los usos de drogas en las sociedades avanzadas desde la perspectiva de género y su intersección con otros ejes de desigualdad, como la edad, la clase social, la raza y la etnia, que marcan tanto el acceso a las diferentes sustancias –en términos normativos y de recursos– como sus diferentes usos y valoraciones sociales. Para ello, exponemos las principales dimensiones del género como categoría analítica: estructural, simbólica e individual. A continuación, pretendemos ampliar esta mirada indagando, desde un marco interseccional, en las diferencias y desigualdades inter e intragénero presentes en diversos usos de drogas. Buscamos con esto romper con categorizaciones estandarizadas, para proyectar un análisis multidimensional desde donde reflexionar sobre cómo otras diferencias imbricadas con el género posibilitan que mujeres y hombres hagan determinados usos de sustancias y condicionan sus efectos sociales.

Full text: The radiation load of population all over the world from medical examinations clearly demonstrate the importance of implementation of quality assurance and quality control programmes into the activities of radiological departments. The basic aim of quality assurance programme is to ensure that the radiation dose is kept as low as reasonably practicable consistent with adequate image quality. As many other fields, the rapid development of techniques brought change-over from the conventional analogue technique to the digital technique. In this connection conventional X-ray film is being abandoned and images are being viewed on either laser film or monitor. The main advantages of using digital equipment lay in improved image quality and diagnostic accuracy through digital image processing, reduction in patient exposure, cost reduction by reduction film usage, more efficient storage and retrieval of radiographic images through picture archiving. Several studies that have been conducted for comparison of various diagnostic examinations performed on digital and analogue X-ray equipment have shown that in barium meal examinations, there is potential for dose saving in the digital image intensifier technique. The aim of this study was to compare measured values of dose-area product for colon investigations using different X-ray equipment types, on digital and one analogue. Our material consisted of 60 randomly selected patients, 24 of them were examined with digital equipment and 36 patients with the analogue equipment. (author)

2012-01-01

For the complexity and the small fault samples of nuclear-powered equipment, a hybrid HMM/SVM method was introduced in fault diagnosis. The hybrid method has two steps: first, HMM is utilized for primary diagnosis, in which the range of possible failure is reduced and the state trends can be observed; then faults can be recognized taking the advantage of the generalization ability of SVM. Experiments on the main pump failure simulator show that the HMM/SVM system has a high recognition rate and can be used in the fault diagnosis of nuclear-powered equipment. (authors)

A new approach to determine the environmental qualification requirements for the safety related equipment

International Nuclear Information System (INIS)

Hasnaoui, C.; Parent, G.

2000-01-01

The objective of the environmental qualification of safety related equipment is to ensure that the plant defense-in-depth is not compromised by common mode failures following design basis accidents with a harsh environment. A new approach based on safety functions has been developed to determine what safety-related equipment is required to function during and after a design basis accident, as well as their environmental qualification requirements. The main feature of this approach is to use auxiliary safety functions established from safety requirements as credited in the safety analyses. This approach is undertaken in three steps: identification of the auxiliary safety functions of each main safety function; determination of the main equipment groups required for each auxiliary safety function; and review of the safety analyses for design basis accidents in order to determine the credited auxiliary safety functions and their mission times for each accident scenario. Some of the benefits of the proposed approach for the determination of the safety environmental qualification requirements are: a systematic approach for the review of safety analyses based on a safety function check list, and the insurance, with the availability of the safety functions, that Gentilly-2 defense-in-depth would not be compromised by design basis accidents with a harsh environment.

Rationalization of the plant maintenance is one of the main topics being investigated in Japanese nuclear power industries. Optimization of the inspection and replacement period of equipments is effective for the maintenance cost reduction. The more realistic model of the replacement policy is proposed in this study. It is based on the classical replacement policy model and its cost is estimated. Then, to consider the inspection for the maintenance, the formulation that includes the risk concept is discussed. Based on it, two variations of the combination of the inspection and the replacement are discussed and the costs are estimated. In this study the effect of the degradation of the equipment is important. The optimized maintenance policy depends on the existence of significant degradation. (author)

2013-01-01

Industrial gammagraphy is a practice widely used as a nondestructive testing technique in Argentina. Experience worldwide has shown the need for an improvement in the intrinsic safety of the equipment used in this lab. In response to this reason, the board of the Nuclear Regulatory Authority (ARN) has considered a proposal to withdraw service movement and much of the equipment inventory scan belonging to industrial facilities nationwide. The main objective of this paper is to present the results of the analysis performed to support the above proposal. The main elements of evaluation can be summarized as follows: I) the teams that do not conform to international recommendations regarding compliance with key safety requirements of international standards such as ISO 3999:2004 (E) R adiation protection - Industrial Apparatus for gamma radiography - Specifications for performance, design and tests ; II) the decision by some manufacturers to discontinue production of certain models of equipment and the provision of spare parts, and III) the validity of certificates bulk type B (U) for transport. In conclusion, it highlights the importance of a regulatory decision supplementary to the Standard AR 7.9.1 concerning the operation of scan equipment industry, based on current international recommendations and Argentina's commitment to good practice and safety culture which can lead to a positive impact on radiation safety in this art

TRIGA reactor main systems

International Nuclear Information System (INIS)

Boeck, H.; Villa, M.

2007-01-01

This module describes the main systems of low power (<2 MW) and higher power (≥2 MW) TRIGA reactors. The most significant difference between the two is that forced reactor cooling and an emergency core cooling system are generally required for the higher power TRIGA reactors. However, those TRIGA reactors that are designed to be operated above 3 MW also use a TRIGA fuel that is specifically designed for those higher power outputs (3 to 14 MW). Typical values are given for the respective systems although each TRIGA facility will have unique characteristics that may only be determined by the experienced facility operators. Due to the inherent wide scope of these research reactor facilities construction and missions, this training module covers those systems found at most operating TRIGA reactor facilities but may also discuss non-standard equipment that was found to be operationally useful although not necessarily required.

Equipment repair in coal mines

Energy Technology Data Exchange (ETDEWEB)

Zhang, S

1982-01-01

Most equipment in Chinese coal mines consists of machinery and equipment produced in the 1950s; the efficiency of 4-62, CTD-57 and 70B/sub 2/ ventilators is 15% lower than that of new ones; that of SSM and AYaP pumps, 10% lower than of modern ones. Equipment renovation is done in three ways: replacing obsolete equipment with new equipment of the same type; improving the performance of existing equipment by introducing efficiency and reconstruction; and replacing obsolete equipment with advanced equipment. It is indicated that the second way, for example, replacement of 4-62 ventilator blades with a maximum efficiency of 73% by 4-72 ventilator blades raises its efficiency to 90%. Replacing the 8DA-8x3 water pump, having a maximum efficiency of 63%, with the 200D 43x3 pump with a maximum efficiency of 78%, enables an electricity savings of 7000 yuan per year, which exceeds all replacement costs (600 yuan). The need to improve equipment maintenance and preventive work to increase equipment service life and to introduce new techniques and efficiency is noted.

Full Text Available Con base en datos provenientes de la Encuesta Nacional sobre Violencia en el Noviazgo, levantada en 2007 entre jóvenes mexicanos de 15 a 24 años de edad, se exPlora el.nivel de conocimiento y uso de anticonceptivos en el contexto de las relaciones de noviazgo. Con este análisis se pretende evidenciar el rol que desempeñan las diversas características sociodemográficas de los jóvenes en el conocimiento y uso de anticonceptivos, con partic cular atención en el papel que juega el género. En general se observan diferencias importantes entre los factores relacionados con el uso de anticonceptivos alguna vez y los factores asociados al uso del condón en las relaciones con la pareja actual. El uso de anticonceptivos aparece asociado positivamente tanto entre los hombres como entre las mujeres con las condiciones socioeconómicas más favorables, con más conocimientos sobre los anticonceptivos, y con un mayor número de compañeros sexuales (sólo para los varones. Entre las mujeres también el hecho de ser estudiante favorece el uso de anticonceptivos. No obstante, cuando se incorporan al análisis elementos proPios de la relación de noviazgo y secircunscribe el análisis a la frecuencia de uso del condón en las relaciones sexuales con la pareja actual, pierden relevancia los factores objetivos y cobran significancia ciertos elementos más subjetivos propios de la relación: la diferencia de edad con la pareja (Para hombres y mujeres, la duración del noviazgo (Para las mujeres, quién decide cuándo y cómo tener sexo (Para los hombres, el apoyo que ofrece la pareja (sólo los hombres, la actitud hacia los roles de género (en el caso de los hombres, y la presen¬cia de violencia emocional (Para los hombres y de violencia física.

Full Text Available Este trabajo presenta las características e historia del software para crear y gestionar bibliotecas digitales Greenstone, desarrollado inicialmente por la Universidad de Waikato, Nueva Zelandia en 1997. En primer lugar, se describe la comunidad de usuarios a nivel global, focalizando en el uso actual que el software ha alcanzado en Argentina: la cantidad de implementaciones disponibles, su evolución, el tipo, tamaño y variedad de los desarrollos existentes, así como su aplicación a la gestión de repositorios digitales de ciencia y tecnología en el ámbito de las instituciones científicas, tecnológicas y de educación superior en Argentina. En segundo lugar, se detallan las acciones llevadas a cabo a partir de la creación del Centro Nacional de Promoción de Greenstone en Argentina en 2009. Datos recabados en encuestas realizadas permitieron observar que las razones predominantes para elegir esta plataforma fueron, entre otras, su facilidad de instalación y configuración, su bajo nivel de requerimiento tecnológico, la generalizada escasez de recursos humanos dedicados a esta actividad, y la complejidad que presentaban los softwares alternativos existentes en ese momento. A lo largo de estos 8 años, tanto los repositorios digitales como los sistemas que los soportan evolucionaron drásticamente, modificando el escenario actual. Paralelamente, en 2016 la nueva versión mayor de Greenstone implementó una reingeniería completa del software para su adaptación a las tecnologías en uso: XML, XSLT, Web-services y Java. Como consecuencia de esto, la comunidad de desarrollo local se plantea nuevos desafíos para la migración de las bibliotecas digitales y repositorios implementados con versiones anteriores.

Full Text Available Objetivo: Indagar el uso de métodos contraceptivos por las puérperas adolescentes a fin de relacionar su (desuso con el embarazo en la adolescencia. Método: Estudio transversal, descriptivo, realizado por medio de un instrumento estructurado con 181 puérperas adolescentes que tuvieron sus partos en el hospital participante de la investigación. Los datos fueron recolectados en el período de diciembre de 2008 a diciembre de 2009. Resultados: El 64,1% de las puérperas usaba algún método contraceptivo antes del embarazo; los métodos más utilizados fueron el anticoncepcional oral (51% y el preservativo masculino (29%. Para el 75% de las adolescentes el embarazo fue planeado y justificado por el deseo y la voluntad propia de experimentar la maternidad. Conclusión: Considerando que casi la mitad de las adolescentes entrevistadas deseaba el embarazo, se deduce que investigar y discutir apenas el uso o no de los métodos contraceptivos no es adecuado. Es necesario profundizar las investigaciones acerca de los significados de ser madre en la adolescencia.

Elbow joint rehabilitation equipment actuated by pneumatic muscles

Vetrice Georgiana

2017-01-01

Full Text Available The mobility of the limbs is an essential prerequisite for the individual’s physical autonomy. For persons suffering from post-traumatic affections of the elbow joint such limited mobility results in barriers in fulfilling personal or professional tasks. Passive motion has certain specific advantages and beneficial effects, thus being highly recommended for the recovery of injured joints. The paper presents a model of rehabilitation equipment that induces continuous passive motion of the elbow, as part of a recovery programme. The equipment is actuated by pneumatic muscles, using compressed air as the source of energy that generates force and motion. The main benefits of the pneumatic actuation system compared to other driving systems are its low cost, simple and robust construction and swift response to commands. Its constructive simplicity and reduced cost adds to the system’s eligibility for deployment in medical units.

This paper deals with the development of a methodology to assess the possibility of equipment damages in low voltage customers due to lightning surges. The main objective is to incorporate this methodology in a computation system that supports distribution companies to determine the possible causes of equipment damages claimed by customers and to decide whether the claims are to be reimbursed or not. The proposed methodology determines whether a specific customer could be affected by a lightning strike according to his/her location and to the lightning main parameters, by using data from a lightning detection system and from the specific equipment surge withstand capability. A specific study using ATP (Alternative Transients Program) was carried out to assess the propagation of lightning surges in electric power distribution systems and their impact over low voltage customers. On the other hand, the withstand capability of the main household appliances was determined by a series of tests carried out in the University's power quality laboratory. The paper details the modeling used for simulation, such as network configuration, grounding points, and modelling of insulator flashover, distribution transformer, low voltage loads. It also presents some results regarding the evaluation of over voltages in low voltage customers installations. A practical method is proposed for assessing the possibility of equipment damage and describes how the existing uncertainties were handled. Also, some issues regarding the withstand capability of electric household appliances to lightning surges are discussed and some results of the laboratory tests are presented. (author)

Full Text Available Engineering equipment is essential part in the construction project and usually manufactured with long lead times, large costs and special engineering requirements. Construction manager targets that equipment to be delivered in the site need date with the right quantity, appropriate cost and required quality, and this entails an efficient supplier can satisfy these targets. Selection of engineering equipment supplier is a crucial managerial process .it requires evaluation of multiple suppliers according to multiple criteria. This process is usually performed manually and based on just limited evaluation criteria, so better alternatives may be neglected. Three stages of survey comprised number of public and private companies in Iraqi construction sector were employed to identify main criteria and sub criteria for supplier selection and their priorities.The main criteria identified were quality of product, commercial aspect, delivery, reputation and position, and system quality . An effective technique in multiple criteria decision making (MCDM as analytical hierarchy process (AHP have been used to get importance weights of criteria based on experts judgment. Thereafter, a management software system for Evaluation and Selection of Engineering Equipment Suppliers (ESEES has been developed based on the results obtained from AHP. This model was validated in a case study at municipality of Baghdad involved actual cases of selection pumps suppliers for infrastructure projects .According to experts, this model can improve the current process followed in the supplier selection and aid decision makers to adopt better choices in the domain of selection engineering equipment suppliers.

Seguindo essa tendência, leis cada vez mais severas devem ser implantadas em relação ao uso desse bem natural. Em um frigorífico de frango, o uso da água ocorre de forma generalizada ao longo de todo o processo industrial. Nesse contexto, o atual estudo teve o objetivo de comparar o consumo de água em um frigorífico brasileiro de frangos de corte (grande porte com modelos já propostos e utilizados em outros países com o intuito de identificar soluções para mitigar perdas provenientes de sua má gestão. Concluiu-se que alterações em alguns pontos-chave do processamento possibilitariam à indústria o uso mais sustentável da água, como substituição da eletronarcose por insensibilização a gás, diminuição da dimensão do tanque de escaldagem ou mudança no processo, substituição do pré-resfriamento por imersão em água por pré-resfriamento a ar, redução da renovação de água nos tanques resfriadores, alterações no sistema de geração do frio em ambientes climatizados, assim como o reúso total ou parcial da água.

Full Text Available INTRODUÇÃO: Há no Brasil crescente utilização de medicamentos industrializados, inclusive durante o ciclo reprodutivo feminino. Na gestação os efeitos dos medicamentos no feto pode resultar em toxicidade com possíveis lesões irreversíveis. Nesse sentido, foi verificada a prevalência do uso de medicamentos, durante a gravidez, na população estudada e sua relação com as características maternas, grupos farmacológicos e fonte de indicação. MÉTODOS: Foram avaliadas, quanto ao uso de medicamentos, 1.620 mulheres que deram à luz em cinco hospitais de atendimento público, privado ou conveniado, da cidade de São Paulo, de julho a setembro de 1993. Os dados referentes ao uso de medicamentos e de outras variáveis foram coletados, por meio de entrevista estruturada, no intervalo de 30 dias consecutivos junto às puérperas. RESULTADOS E CONCLUSÕES: A relação entre escolaridade materna e atendimento hospitalar revelou desigualdade social no acesso aos diversos tipos de serviço de assistência ao parto. A prevalência do uso de pelo menos um medicamento foi de 97,6%, com média de 4,2 medicamentos por mulher. A prevalência do uso de medicamentos por indicação médica e por automedicação foi de 94,9% e 33,5%, respectivamente. As medicações mais usadas, excluindo-se as vitaminas, sais minerais e vacinas, foram os analgésicos, antiácidos, antieméticos e antiespasmódicos. Usuárias com maior uso de medicamentos tiveram as seguintes características: acima de 29 anos de idade, casadas, terceiro grau completo, atividade remunerada e acesso aos serviços privados de saúde. A assistência médica desempenhou papel facilitador no acesso ao uso de medicamentos durante o período gestacional. As mulheres deveriam ser conscientizadas dos riscos em potencial a que expõem seus fetos ao fazerem uso de tantas medicações. O pré-natalista deveria repensar seu papel diante desta problemática.

2017-08-01

The significant growth of volumes and distances on road transportation led to the necessity of finding solutions to increase water transportation market share together with the handling and transfer technologies within its terminals. It is widely known that the biggest times are consumed within the transport terminals (loading/unloading/transfer) and so the necessity of constantly developing handling techniques and technologies in concordance with the goods flows size so that the total waiting time of ships within ports is reduced. Port development should be achieved by harmonizing the contradictory interests of port administration and users. Port administrators aim profit increase opposite to users that want savings by increasing consumers’ surplus. The difficulty consists in the fact that the transport demand - supply equilibrium must be realised at costs and goods quantities transiting the port in order to satisfy the interests of both parties involved. This paper presents a port equipment sizing model by using queueing theory so that the sum of costs for ships waiting operations and equipment usage would be minimum. Ship operation within the port is assimilated to a mass service waiting system in which parameters are later used to determine the main costs for ships and port equipment.

This document is intended to be used as guidance for design engineers who are involved in design of new equipment slated for use in Flammable Gas Waste Storage Tanks. The purpose of this document is to provide design guidance for all new equipment intended for application into those Hanford storage tanks in which flammable gas controls are required to be addressed as part of the equipment design. These design criteria are to be used as guidance. The design of each specific piece of new equipment shall be required, as a minimum to be reviewed by qualified Unreviewed Safety Question evaluators as an integral part of the final design approval. Further Safety Assessment may be also needed. This guidance is intended to be used in conjunction with the Operating Specifications Documents (OSDs) established for defining work controls in the waste storage tanks. The criteria set forth should be reviewed for applicability if the equipment will be required to operate in locations containing unacceptable concentrations of flammable gas

Full Text Available In this paper we aim to investigate the use of web sites. We add an explanatory model from the perspective of design impact in the end-user satisfaction. In this model we identify seven main design factors: functionality, accessibility, findability, usefulness, aesthetics, credibility and usability. They have been categorized as hygienic or motivator according to their orientation towards the prevention of the frustration of use or the satisfaction of use they cause. The usability is the more important of those factors because it has a transversal function in the model: the usability interrelates the rest of design factors. We discuss the importance of each factor in the user experience, depending on the interactive context, and also the utility of analysing satisfaction from both hygienic-motivator dimensions.

El presente trabajo se propone indagar en el fenómeno de uso de sitios web, aportando un modelo explicativo desde la perspectiva del impacto del diseño en la satisfacción-frustración del usuario final. En el modelo se identifican siete factores principales de diseño –funcionalidad, accesibilidad, findability, utilidad, estética, credibilidad y usabilidad– clasificados como higiénicos o motivadores, según estén orientados a impedir la frustración de uso o a provocar satisfacción de uso respectivamente. De estos factores, la usabilidad cobra especial importancia por su función vertebral del modelo, interrelacionando el resto de factores de diseño. Se discute el peso de cada factor en la experiencia del usuario dependiendo del contexto interactivo, así como la utilidad del análisis de la satisfacción desde su doble dimensión higiénico-motivadora.

RIASSUNTO. La terapia farmacologica nei pazienti con disturbo da uso di alcol riveste un ruolo centrale nel progetto terapeutico, altamente contestualizzato in un approccio multidisciplinare. Sebbene i trattamenti non farmacologici per la dipendenza da alcol risultino ben strutturati e in continua evoluzione, dal punto di vista medico le possibilità di intervento sono realmente ristrette, con poche molecole a disposizione approvate per il disturbo da uso di alcol: nello specifico, l'acamprostato, il naltrexone e, più recentemente, il nalmefene tra gli anticraving; il disulfiram tra gli avversivanti. Nuovi approcci sperimentali stanno cercando di ampliare tale gamma attraverso l'utilizzo di farmaci off-label. Evidenze scientifiche devono supportare l'indicazione terapeutica, quest'ultima deve dimostrarsi "cucita" sulle esigenze del paziente e sulle comorbilità presenti tenendo conto del profilo bio-psico-sociale individuale. Fondamentale risulta il follow-up per valutare la ritenzione in trattamento e il monitoraggio degli outcome alcologici.

Momentos liminares: dinâmica e significados no uso do preservativo

Emídio Gune

Full Text Available O preservativo tem sido colocado no centro das estratégias de prevenção do VIH e das gravidezes não planificadas. Este artigo analisa a dinâmica e os significados associados ao seu uso e as implicações sobre os pressupostos subjacentes à sua promoção. Enquanto os pressupostos epidemiológicos consideram o uso do preservativo condição para a prática do sexo seguro, os pressupostos sociais tendem a considerar que as relações sexuais socialmente aceitáveis são per si seguras, excluindo, por conseguinte, o seu uso. Dado que ao longo da sua vida sexual activa os actores sociais alternam as suas práticas sexuais entre perigosas e seguras, verifica-se que o seu uso é, sobretudo, inconsistente. Tal cenário obriga a repensar a centralidade do preservativo como mecanismo de redução consistente do risco de uma gravidez não planificada ou de infecções de transmissão sexual.The prophylactic or condom has played a key role in the development of strategies for preventing HIV and unwanted pregnancy. This article examines the dynamics and meanings associated with its use, and the implications of the assumptions which underlie the promotion of this form of contraception. Whereas those whose arguments are based on epidemiological assumptions see prophylactic use as a mean of practising safe sex, those who argue from socially-based assumptions tend to see socially acceptable sexual relations as safe in themselves, and therefore as not requiring the use of the prophylactic. Given that social actors alternate between safe and unsafe sexual practices over the course of their lives, the facts are that prophylactic use is, above all, inconsistent. This requires us to rethink the key role of the prophylactic as a mean of consistently reducing the risk of unwanted pregnancy and of sexually transmitted infections.

Full Text Available OBJETIVO: Avaliar a qualidade do uso de medicamentos através da análise do padrão do uso, do grau de concordância com listas de medicamentos essenciais, do valor terapêutico e das interações medicamentosas encontradas entre mulheres com mais de 60 anos. MÉTODOS: Foram pesquisadas 634 mulheres que freqüentam a Universidade Aberta da Terceira Idade da Universidade do Estado do Rio de Janeiro. Os dados foram coletados através de questionário padronizado e testado. As variáveis utilizadas foram relativas aos medicamentos e a seu modo de utilização. As unidades de análise foram o medicamento e o indivíduo. RESULTADOS: Das 634 mulheres estudadas, 9,1% não tomam qualquer tipo de medicamento. A média de medicamentos consumidos foi de 4,0 por mulher. Das 2.510 especialidades farmacêuticas citadas, há 538 princípios ativos diferentes. Cerca de 26% dos medicamentos são concordantes com as recomendações da Organização Mundial da Saúde, e 17%, com as da Relação Nacional de Medicamentos Essenciais. Cerca de 17% dos medicamentos são inadequados para o uso. No que diz respeito a redundâncias, 14,1% das mulheres podem sofrer conseqüências decorrentes desse evento. Quanto às interações medicamentosas, 15,5% das entrevistadas estão expostas às principais interações. CONCLUSÕES: Os dados sugerem que o padrão do uso dos medicamentos entre as idosas é bastante influenciado pela prescrição médica e que sua qualidade é prejudicada pela baixa seletividade do mercado farmacêutico.

Full Text Available OBJETIVO: Avaliar a qualidade do uso de medicamentos através da análise do padrão do uso, do grau de concordância com listas de medicamentos essenciais, do valor terapêutico e das interações medicamentosas encontradas entre mulheres com mais de 60 anos. MÉTODOS: Foram pesquisadas 634 mulheres que freqüentam a Universidade Aberta da Terceira Idade da Universidade do Estado do Rio de Janeiro. Os dados foram coletados através de questionário padronizado e testado. As variáveis utilizadas foram relativas aos medicamentos e a seu modo de utilização. As unidades de análise foram o medicamento e o indivíduo. RESULTADOS: Das 634 mulheres estudadas, 9,1% não tomam qualquer tipo de medicamento. A média de medicamentos consumidos foi de 4,0 por mulher. Das 2.510 especialidades farmacêuticas citadas, há 538 princípios ativos diferentes. Cerca de 26% dos medicamentos são concordantes com as recomendações da Organização Mundial da Saúde, e 17%, com as da Relação Nacional de Medicamentos Essenciais. Cerca de 17% dos medicamentos são inadequados para o uso. No que diz respeito a redundâncias, 14,1% das mulheres podem sofrer conseqüências decorrentes desse evento. Quanto às interações medicamentosas, 15,5% das entrevistadas estão expostas às principais interações. CONCLUSÕES: Os dados sugerem que o padrão do uso dos medicamentos entre as idosas é bastante influenciado pela prescrição médica e que sua qualidade é prejudicada pela baixa seletividade do mercado farmacêutico.

Full Text Available En el capítulo tercero de la TPE, Jevons recurre al uso de las probabilidades como un método alternativo para analizar el intercambio de las mercancías. Jevons, decide no continuar con el uso de las probabilidades en los capítulos siguientes; su teoría se bifurca imperando el uso del cálculo diferencial. La explicación de esta bifurcación radica en la existencia de dos métodos alternativos para explicar el análisis del intercambio: La teoría de las probabilidades y el cálculo diferencial. Usar el cálculo diferencial no significaba que fuese el método más eficiente, pues no sólo existieron errores al maximizar como muestra Westergaard (1874, sino también problemas metodológicos, como muestran Stigler (1956 y Blaug (1985. Por otro lado, el método de las probabilidades habría significado para el análisis del intercambio, un problema de valores esperados y un camino totalmente diferente para la revolución marginalista.

Use of Equipment Information System (EQUIS) to determine priority for purchasing safeguards equipment

International Nuclear Information System (INIS)

Silberberg, S.

1988-01-01

To manage its large world-wide inventory of safeguards equipment, the IAEA Safeguards department uses a computerized Equipment Information System (EQUIS). EQUIS data have been analyzed using Queueing Theory to determine if inventory is adequate to meet inspector demands and in those cases where it is inadequate, to indicate how many additional units should be procured. Results are tabulated for various types of non-destructive analysis (NDA) equipment. For equipment where there is a high turnover and hence a large amount of data, the analysis provides a powerful tool for assisting procurement decisions

The wearing of personal equipment can cause specific changes in muscle activity and posture. In the present study, we investigated the influence of differences in equipment related weight loading and load distribution on plantar pressure. In addition, we studied functional effects of wearing different equipment with a particular focus on relevant changes in foot shape. Static and dynamic pedobarography were performed on 31 male soldiers carrying increasing weights consisting of different items of equipment. The pressure acting on the plantar surface of the foot increased with higher loading, both under static and dynamic conditions (p feet deformities which seem to flatten at an earlier load condition with a greater amount compared to subjects with normal arches. Improving load distribution should be a main goal in the development of military equipment in order to prevent injuries or functional disorders of the lower extremity.

It is shown that a special shovel is a feature of the structure of the drives of the main mechanisms (mechanisms of lifting and pressure) of career excavators with working equipment, the presence in the transfer device of a two-crank-lever mechanism of working equipment that connects the main mechanisms with the working body (bucket). In this case, the transformation of the mechanical energy parameters of the motors into energy-force parameters realized at the cutting edge of the bucket (teeth) takes place depending on the type of the kinematic scheme of the two-link-lever mechanism. The concept of “control function” defining the relationship between the parameters characterizing the position of the bucket in the face (the coordinates of the tip of the cutting edge of the bucket, the digging speed) and the required control level are introduced. These are the values of the lifting and head speeds ensuring the bucket movement along a given trajectory.

This article documents the methods applied in production control technics specifically focused on commonly used parameter OEE (Overall Equipment Effectiveness). The indicators of extensive and intensive use of equipment are considered. Their appointment this is comparison in the same type of production within the industry and comparison of single-type and / or different types of equipment in terms of capacity. However, it is shown that there is no possibility of revealing the reasons for the machine’s operation: productive / unproductive, with disturbances. Therefore, in the article reveals the approaches to calculating the indicator characterizing the direct operation of the equipment. The Machine Load coefficient is approaching closely to the indicator of the efficiency of the use of equipment. Methods analysis is proceeded through the historically applied techniques such as “Stopwatch” and “Motion” studies. Was performed the analysis of the efficiency index of OEE equipment using the comparable indexes performance of equipment in the Russian practice. An important indicator of OEE contains three components. The meaning of each of them reflects historically applicable indicators. The value of the availability of equipment indicator is close to the value of the equipment extensibility index. The value of the indicator of the efficiency of work can be compared with the characteristic of the capacity of the equipment and the indicator of the quality level can meet the requirements for compliance with the manufacturing technology. Shown that the sum of the values of the coefficient of “Availability” of the equipment and the value of the “Factor of compaction of working hours” are one. As well as the total value of the indicator “level of quality” and the coefficient of marriage given in the result unit. The measurability of the indicators makes it possible to make a prediction about efficiency of the equipment.

Technology transfer equipment qualification methodology for shelf life determination

International Nuclear Information System (INIS)

Anderson, J.W.

1995-01-01

Discussions with a number of Nuclear Utilities revealed that equipment qualified for 10 to 40 years in the harsh environment of the plant was being assigned shelf lives of only 5 to 10 years in the benign environment of the warehouse, and then the materials were being trashed. One safety-related equipment supplier was assigning a 10-year qualified life, from date of shipment, with no recognition of the difference in the aging rate in the plant vs. that in the warehouse. Many suppliers assign shelf lives based on product warranty considerations rather than actual product degradation. An EPRI program was initiated to evaluate the methods used to assign shelf lives and to adapt the Arrhenius methodology, used in equipment qualification, to assign technically justifiable shelf lives. Temperature is the main factor controlling shelf life; however, atmospheric pressure, humidity, ultraviolet light, ozone and other atmospheric contaminants were also considered. A list of 70 representative materials was addressed in the program. All of these were found to have shelf lives of 14 years to greater than 60 years, except for 19 items. For 18 of these items, there was no data available except for the manufacturer's recommendation

Chapter 12. Space Heating Equipment

Energy Technology Data Exchange (ETDEWEB)

Rafferty, Kevin D.

1998-01-01

The performance evaluation of space heating equipment for a geothermal application is generally considered from either of two perspectives: (a) selecting equipment for installation in new construction, or (b) evaluating the performance and retrofit requirements of an existing system. With regard to new construction, the procedure is relatively straightforward. Once the heating requirements are determined, the process need only involve the selection of appropriately sized hot water heating equipment based on the available water temperature. It is important to remember that space heating equipment for geothermal applications is the same equipment used in non-geothermal applications. What makes geothermal applications unique is that the equipment is generally applied at temperatures and flow rates that depart significantly from traditional heating system design. This chapter presents general considerations for the performance of heating equipment at non-standard temperature and flow conditions, retrofit of existing systems, and aspects of domestic hot water heating.

Farm Equipment Manufacturing and Maintenance Services by Blacksmiths in Mali

2004-03-01

Full Text Available The Office of Niger has largely contributed to the spread of animal traction technology. Draft animals being largely available, the major constraint has been the high price of imported equipment relative to the purchasing power of the farmers. From the 1980s, considerable quantities of animal traction implements have been introduced particularly by the Arpon project. These implements were assembled at a central workshop and distributed to farmers through a medium term credit facility, including purchase of oxen. Meanwhile support was given to the upgrading of the first blacksmiths’ workshops, providing them with basic equipment, on credit. In the Southern Mali cotton production zone as well as in the Segou River plains rice producing area, associations of blacksmiths have also been created. These networks have greatly contributed to the improvement of skills and turn over of their members. Blacksmiths have become the main producers of animal traction equipment in Mali. Also, farmers greatly appreciate after-sales services. Nevertheless, the sector is still handicapped by major constraints, which are the high price of imported steel, the poor distribution network for electricity and its high cost, as well as the actual absence of credit facilities for blacksmiths. Therefore, in 1997, the blacksmiths’ association of the Office of Niger zone, together with those of the two other zones have created the CMDT/ON/ORS Blacksmiths’ Federation. Its main purposes are the provision and distribution of raw materials (steel products, facilitation of workshop upgrading, organization of training and exchange sessions, and promotion of product marketing.

Within the framework of the European Community's PHARE Programme of improvement to facilities, their operating systems, equipment and buildings of the Kozloduy NPP in Bulgaria, plant safety during seismic events is considered to be an issue of overriding importance, especially in view of the earthquakes the region suffered during the last decade. Westinghouse Energy Systems International (WESI) and Empresarios Agrupados (EA) have initiated an intensive programme for physical upgrading of equipment with a view to augmenting its seismic capability and, at the same time, to studying design modifications in the diesel-generator buildings, pump house and main building structures (turbines, electrical building). The implementation of these modifications requires an in situ inspection of the real conditions of the various elements, analyses, conceptual design and detail engineering, all of which has to be done in short periods of time using resources available at the plant. This activity is performed by the companies mentioned above, with the collaboration of two engineering companies, Energoproekt of Bulgaria and INITEC of Spain. This paper describes the activities developed and the treatment given to the various aspects of improvement of the seismic capability of equipment and structures. (author)

Full Text Available Entre os jovens, o uso de drogas ilícitas é um problema de saúde coletiva que desperta atenção. Poucos estudos sobre motivos para o não uso de drogas exploram o real papel da informação como método preventivo. O objetivo do estudo é analisar, entre adolescentes e jovens em situação de risco, os motivos para o não uso de drogas ilícitas, destacando o impacto da informação como fator protetor. Através de metodologia qualitativa, adotou-se uma amostra intencional, selecionada por informantes-chave e por "bola de neve". Foram entrevistados 62 adolescentes e jovens entre dezesseis e 24 anos, de baixa classe socioeconomica. Destes, 32 eram não usuários de drogas (NU e trinta eram usuários pesados (U. Entre o grupo NU, a informação destacou-se como principal motivo de não uso, através do conhecimento de aspectos positivos e negativos. O principal meio de veiculação foi a família, seguido da observação da experiência negativa vivenciada por amigos que já faziam abuso. Em contrapartida, no grupo U, prevaleceu a falta de informação ou a disponibilidade de conhecimentos vagos. Dispor de informações adequadas sobre o tema "drogas" parece essencial à prevenção do uso experimental entre adolescentes e jovens em situação de risco. No entanto, a informação que mais parece eficaz é a transmitida pela família.Illicit drug consumption among youngsters is a public health concern that requires attention. However, little research has highlighted the importance of "drug information availability" among protection factors. The objective of the study is to identify, from the point of view of youngsters at risk, what factors could prevent them to try illicit drugs, focusing on the importance of "drug information availability". An intentional sample was selected, composed by 62 youngsters divided into two groups: (NU non illicit users N=32 and (U users N=30.

To compare the prevalence of contraceptive use among teenage mothers who were participating, and teenage mothers who were not participating, in a program in Jamaica that had been established to deal with the country's serious problem of repeat pregnancies among adolescents. Methods. A historical cohort design was used to assess the impact that the Women's Centre of Jamaica Foundation (WCJF Programme for Adolescent Mothers had on contraceptive use among the target population of adolescents 16 years and under who had experienced a first live birth in 1994. Results. Contraceptive use at first intercourse was found to be higher among WCJF program participants (44% than among nonparticipants (37%, but this difference was not significant (P = 0.35. Contraceptive use after first live birth was also higher among WCJF program participants (94% than among nonparticipants (86%, and this difference was significant (P = 0.04. Contraceptive prevalence at last intercourse (in 1998 did not differ between participants and nonparticipants (both 69%. Conclusions. Contraceptive use among this population in Jamaica was highest when the respondents' perception of vulnerability to pregnancy was most acute, that is, after the first live birth. All adolescents, both males and females, need to be educated about the importance of sustained and effective use of contraception in order to reduce the risk of unintended pregnancy and sexually transmitted diseases.Objetivos.

Uso político da religião e uso religioso da política: uma análise a partir de duas interpretações exemplares - Marsílio e Maquiavel

Full Text Available Estamos confrontados na atualidade com um vertiginoso crescimento do fenômeno religioso. Isso pode ser observado não apenas pelo surgimento de novas religiões e o aumento da frequência aos cultos, mas também pela presença da linguagem religiosa no discurso político de tal modo que podemos falar num uso político da religião e um uso religioso da política. Quando abordamos as religiões na longa duração, percebemos que em todas elas coabitam estes dois aspectos, contraditórios e excludentes apenas na aparência. Esta constatação leva ao questionamento: existiriam religiões mais políticas, ou mais conquistadoras, do que outras? Ou então, talvez, a natureza belicosa das religiões emergiria a partir do momento em que elas se erigem em ideologias, da mesma forma como as ideologias se impõem politicamente quando agem à maneira de religiões? Neste trabalho nos orientaremos por esta hipótese para explorar a relação ambígua entre política e religião, pois foi precisamente após a morte das ideologias que as religiões, independente do credo, retornaram com toda a força. Para tanto, tomaremos como referência teórica dois pensadores, Marsílio de Pádua e Nicolau Maquiavel, para pensar, respectivamente, o uso religioso da política e o uso político da religião.

2001-01-01

The radiation load of population all over the world from medical examinations clearly demonstrates the importance of the introduction of the quality assurance and quality control programmes into the activities of radiology departments. The basic aim of quality assurance program is to ensure that the radiation dose is kept as low as reasonably practicable while still providing an adequate image quality. As many other fields, the rapid development of techniques brought change-over from the conventional analogue technique to the digital technique. In this process, the conventional X-ray film is being abandoned and images are being viewed on either laser film or monitor. The main advantages of using digital equipment lay in improved image quality and diagnostic accuracy through digital image processing, reduction in patients exposure, cost reduction by reduction of the film usage, more efficient storage and retrieval of radiographic images through picture archiving. Several studies that have been conducted for comparison of various diagnostic examinations show , that there is potential for dose saving in the digital image intensifier technique. The aim of this study was to compare measured values of dose-area product for colon investigations using different X-ray equipment types, two digital and two analogue. Our material consisted of 169 randomly selected patients, 115 of them were examined with digital equipment and 54 patients with the analogue equipment. The obtained results have confirmed the dose reduction and increase of diagnostic accuracy when using the digital equipment, with the added benefit of a good image quality. (authors)

French regulation requires licensee to qualify electrical equipment important to safety for service in nuclear power plants to ensure that the equipment can perform its safety function under the set of plausible operating conditions. The French regulatory texts entitled Fundamental safety rules have classified safety related electrical equipment in three main categories: k1, k2, k3, according to their location and operating conditions. The definition of a design basis accident test profile must account for margins applied to thermal hydraulic code outputs. Specific safety margins was added to cover uncertainties in qualification test representativity. Up to now, accidental sequence studies have shown the validity of such a qualification test profile. On the other hand, the results from post accident simulation tests have shown that it is useful not only to validate post accident operating life but also to reveal failures initiated during previous tests [fr

2017-04-19

Gavi, the Vaccine Alliance, supports immunisation programmes in eligible countries to reach children with lifesaving vaccines. Dramatic improvement in the scale and performance of current cold chain systems is required to extend the reach of immunisation services - especially for children living in remote locations - to advance progress towards full vaccine coverage. Achieving these improvements will require a healthier market for cold chain equipment where the products meet user needs, are sustainably priced, and are available in sufficient quantities to meet demand. Yet evidence suggests that the cold chain market has suffered from several failures including limited demand visibility, fragmented procurement, and insufficient information exchange between manufacturers and buyers on needs and equipment performance. One of Gavi's strategic goals is to shape markets for vaccines and other immunisation products, including cold chain equipment and in 2015, Gavi created a new mechanism - the Cold Chain Equipment (CCE) Optimisation Platform - to strengthen country cold chain systems by offering financial support and incentives for higher performing CCE. The main objective of the CCE Platform is to get more equipment that is efficient, sustainable, and better performing deployed to every health facility where it is required at an affordable price. To achieve these objectives, Gavi is putting in place tested market shaping approaches and tools adapted for the CCE market: the development of market strategies or 'roadmaps'; improvement of product performance through the development of target product profiles (TPPs); strategic engagement with CCE manufacturers and countries to enhance information sharing; and tailoring procurement tactics to the CCE market. These approaches and tools will allow for increased demand and supply of higher-performing, cost-effective and quality products. By strengthening immunisation systems with improved cold chain equipment, Gavi countries can

Equipment Operational Requirements

Energy Technology Data Exchange (ETDEWEB)

Greenwalt, B; Henderer, B; Hibbard, W; Mercer, M

2009-06-11

The Iraq Department of Border Enforcement is rich in personnel, but poor in equipment. An effective border control system must include detection, discrimination, decision, tracking and interdiction, capture, identification, and disposition. An equipment solution that addresses only a part of this will not succeed, likewise equipment by itself is not the answer without considering the personnel and how they would employ the equipment. The solution should take advantage of the existing in-place system and address all of the critical functions. The solutions are envisioned as being implemented in a phased manner, where Solution 1 is followed by Solution 2 and eventually by Solution 3. This allows adequate time for training and gaining operational experience for successively more complex equipment. Detailed descriptions of the components follow the solution descriptions. Solution 1 - This solution is based on changes to CONOPs, and does not have a technology component. It consists of observers at the forts and annexes, forward patrols along the swamp edge, in depth patrols approximately 10 kilometers inland from the swamp, and checkpoints on major roads. Solution 2 - This solution adds a ground sensor array to the Solution 1 system. Solution 3 - This solution is based around installing a radar/video camera system on each fort. It employs the CONOPS from Solution 1, but uses minimal ground sensors deployed only in areas with poor radar/video camera coverage (such as canals and streams shielded by vegetation), or by roads covered by radar but outside the range of the radar associated cameras. This document provides broad operational requirements for major equipment components along with sufficient operational details to allow the technical community to identify potential hardware candidates. Continuing analysis will develop quantities required and more detailed tactics, techniques, and procedures.

Nowakowski, Piotr

2016-11-01

Government agencies have implemented regulations to reduce the volume of waste electrical and electronic equipment to protect the environment and encourage recycling. The effectiveness of systems through which waste electrical and electronic equipment is collected and recycled depends on (a) the development and operation of new programmes to process this material and (b) on information dissemination programmes aimed at manufacturers, retail sellers, and the consuming public. This study analyses these two elements. The main focus is to better understand household residents' behaviour in regards to the proper methods of handling waste electrical and electronic equipment and possible storage of the obsolete equipment that brings disturbances with collection of the waste equipment. The study explores these issues depending on size of municipality and the household residents' knowledge about legal methods of post-consumer management of waste electrical and electronic equipment in Poland, where the collection rate of that type of waste is about 40% of the total mass of waste electrical and electronic equipment appearing in the market.The research was informed by various sources of information, including non-government organisations, Inspectorate of Environmental Protection and Central Statistics Office in Poland, questionnaires, and interviews with the household residents. The questionnaires were distributed to daytime and vocational students from different universities and the customers of an electronic equipment superstore. The results show that a resident's behaviour in regards to the handling of obsolete waste electrical and electronic equipment can significantly reduce the collection rate, especially when the waste is discarded improperly - mixed with municipal waste or sold in scrapyards. It is possible to identify points that are necessary to be improved to achieve a higher collection rate. © The Author(s) 2016.

When an operator hears sounds in a plantsite, the operator compares normal sounds of equipment which he previously heard and remembered with sounds he actually hears, to judge if they are normal or abnormal. According to the method, there is a worry that abnormal conditions can not be appropriately judged in a case where the number of objective equipments is increased and in a case that the sounds are changed gradually slightly. Then, the device of the present invention comprises a plurality of monitors for monitoring the operation sound of equipments, a recording/reproducing device for recording and reproducing the signals, a selection device for selecting the reproducing signals among the recorded signals, an acoustic device for converting the signals to sounds, a switching device for switching the signals to be transmitted to the acoustic device between to signals of the monitor and the recording/reproducing signals. The abnormality of the equipments can be determined easily by comparing the sounds representing the operation conditions of equipments for controlling the plant operation and the sounds recorded in their normal conditions.

After outlining some international schemes for open data, this study examines both the current legislative framework and some of the main existing initiatives in Spain. This evidence enables the identification of some shortcomings, among which is some deficit in interoperability. Then the analysis deals with the rules regulating data re-use under public copyright licenses and its application to the Spanish case. The findings show that the Creative Commons licenses properly fit into the Spanish legislation since they include all forms of dissemination and exploitation therein. Therefore, such licenses seem to be recommendable.Este artículo recoge la creciente tendencia en favor de los datos abiertos generados por las administraciones públicas y aborda su reutilización mediante el uso de licencias-tipo. Tras exponer algunas propuestas internacionales de apertura de datos, se examina la incidencia en España a través del marco legislativo actual y algunas de las principales iniciativas existentes, que aún presentan determinadas carencias, entre las que destaca cierto déficit de interoperabilidad. A continuación se analiza la regulación normativa de la reutilización de datos mediante el uso de licencias-tipo y se reflexiona sobre su aplicación al caso español. Se constata que las licencias Creative Commons se adaptan a la legislación española vigente porque contemplan todas las modalidades de difusión y explotación recogidas en la misma, lo que hace su uso recomendable.

Making petroleum equipment safe, a priority

International Nuclear Information System (INIS)

1999-01-01

Changes to the 'Act respecting the use of petroleum products' have been announced effective May 1, 1999. The changes have been made to reduce problems which can be attributed to petroleum product leaks. The new regulations will make owners and users of petroleum equipment, including underground and above-ground storage equipment and commercial storage tanks, more accountable for the use of their own equipment. The emphasis in the new regulations is based upon the storage capacity of petroleum equipment and the risks associated with this equipment, rather than the on the activities of the owners concerned. Accordingly, the new regulations call for stricter requirements for high-risk equipment, a private equipment inspection plan, a two-year operating permit, replacing the current permits and certificates, a tariff structure based on the risks associated with the equipment, and deregulation of commercial activities involving petroleum products that require no equipment. Additionally, the amendments to the Act transfer responsibility for administration to the Regie du batiment and to the Ministere des Transports. Details of each of these changes are explained

Seismic qualification of non-safety class equipment whose failure would damage safety class equipment

International Nuclear Information System (INIS)

LaSalle, F.R.

1991-01-01

Both Code of Federal Regulations, Title 10, Part 50, and US Department of Energy Order 6340.1A have requirements to assess the interaction of non-safety and safety class structures and equipment during a seismic event to maintain the safety function. At the Hanford Site, a cost effective program has been developed to perform the evaluation of non-safety class equipment. Seismic qualification is performed by analysis, test, or upgrading of the equipment to ensure the integrity of safety class structures and equipment. This paper gives a brief overview and synopsis that address design analysis guidelines including applied loading, damping values, component anchorage, allowable loads, and stresses. Test qualification of equipment and walkdown acceptance criteria for heating ampersand ventilation (H ampersand V) ducting, conduit, cable tray, missile zone of influence, as well as energy criteria are presented

Equipment standards for interventional cardiology

International Nuclear Information System (INIS)

Dowling, A.; Gallagher, A.; Walsh, C.; Malone, J.

2005-01-01

Interventional radiology has seen rapid growth in cardiology and represents an alternative to hazardous surgery. Recently there has been a substantial growth in the number of procedures being performed and interventional cardiology (IC) procedures are the most common interventional procedures in Europe. Advances in imaging technology have facilitated the development of increasingly complex radiological IC equipment. Currently, the technology is developing at a rate ahead of supporting research, equipment standards and a regulatory framework. International standards play a key role in the design, manufacture and performance of radiological IC equipment. A survey of 12 IC systems (15 imaging chains) was conducted in Irish hospitals. The aim of the study was to assess the imbalance between rapidly advancing technology and existing standards and to propose recommendations for new IC equipment standards. The results demonstrate the need for definitive equipment requirements and standardisation in the design, manufacture, acceptance and maintenance of IC equipment. (authors)

Dredemis, G.; Fourest, B.; Giroux, C.

1985-07-01

The paper presents the experience of Hopkinson MSIVs over about 40 reactor-years (1977 to 1984) of operation at Fessenheim and Bugey units (900 MWe PWR). The various problems encountered including ageing effects on auxiliary equipments and increases in closure time are discussed. The corrective actions undertaken by the utility and the safety assessment of these events performed by the french safety authorities are also described. This study is the synthesis of an in-depth analysis of Main Steam Isolation Valves (MSIV) and their auxiliary circuits equipping the Bugey and Fessenheim 900 MWe PWR nuclear power plants. These valves are different from those installed in the other French 900 MWe PWR reactors. The evaluation of the operation of these valves was made on the basis of incidents which occured during operation of the units or during the periodic tests, as well as anomalies discovered during maintenance operations. This analysis proved that the anomalies related to the design of the valves, as well as to their manufacture and installation, had been correctly dealt with. Furthermore, it should have also revealed potential anomalies due to ageing of the equipment

Equipment installation structure of roof slab for tank type FBR and method of equipment installation

International Nuclear Information System (INIS)

Sakai, Takao; Yamakawa, Masanori; Otsuka, Masaya; Sekine, Katsuhisa

1986-01-01

Purpose: To reduce equipment thermal stress and deformation by eliminating uneven temperature distribution caused at the equipment through section of the roof slab for the tank FBR, and at the same time, simplify the structure installation. Method: Multiple number of vertical fin projects are fit on the equipment through-section inside wall for the roof slab and the cylindrical equipment peripheral wall, and with these projected fins, the ring space of the through section is vertically divided into multiple sections in the circumferential direction. The vertical fins on the through-section inside wall and the fins on the equipment peripheral wall are contacted with each other by revolving them in the lateral direction. As a result, the natural convection caused by the difference of temperatures in the vertical direction of the ring space becomes a convection within each sector divided, and never generates circumferential circulation, which reduce uneven temperature distribution caused at the equipment through section.

Bletchly, P. J.

Pressure equipment constitutes a significant investment in capital and a major proportion of potential high-risk plant in many operations and this is particularly so in an alumina refinery. In many jurisdictions pressure equipment is also subject to statutory regulation that imposes obligations on Owners of the equipment with respect to workplace safety. Most modern technical standards and industry codes of practice employ a risk-based approach to support better decision making with respect to pressure equipment. For a management system to be effective it must demonstrate that risk is being managed within acceptable limits.

Estudios realizados con preescolares y escolares han demostrado un mejor rendimiento escolar y un efecto positivo en habilidades de lectura, matemáticas, y en general cognitivas, en niños que utilizan un computador con software educativo quince a veinte minutos por día. El objetivo del presente estudio fue evaluar la progresión de las habilidades verbales, integración viso-motora y de lectura en niños que usaron computadores y compararlos con un grupo que continuó con la educación tradicional. Todos los niños fueron estudiados antes de iniciar la intervención pedagógica. La evaluación inicial mostró una puntuación inferior para la edad en todas las pruebas aplicadas. El 11% de la población estudiada se catalogó como en alto riesgo de tener problemas en el aprendizaje. En la segunda evaluación se encontró un cambio positivo respecto a la puntuación inicial. Sin embargo, a excepción de algunos ítems, no se encontraron diferencias signifi cativas al comparar los grupos de uso o no de computadores. En conclusión, las políticas acerca del uso de computadores deben ser revaluadas, pues los niños de nuestras escuelas públicas provienen de ambientes privados de oportunidades para el uso de tecnología

Maintenance program guidelines for programmatic equipment

International Nuclear Information System (INIS)

1994-11-01

The Division Directors at Lawrence Berkeley Laboratory are responsible for implementing a maintenance program for research equipment (also referred to as programmatic equipment) assigned to them. The program must allow maintenance to be accomplished in a manner that promotes operational safety, environmental protection and compliance, and cost effectiveness; that preserves the intended functions of the facilities and equipment; and that supports the programmatic mission of the Laboratory. Programmatic equipment -- such as accelerators, lasers, radiation detection equipment, and glove boxes -- is dedicated specifically to research. Installed equipment, by contrast, includes the mechanical and electrical systems installed as part of basic building construction, equipment essential to the normal functioning of the facility and its intended use. Examples of installed equipment are heating, ventilating, and air conditioning systems; elevators; and communications systems. The LBL Operating and Assurance Program Plan (PUB-3111, Revision 4) requires that a maintenance program be prepared for programmatic equipment and defines the basic maintenance program elements. Such a program of regular, documented maintenance is vital to the safety and quality of research activities. As a part of that support, this document offers guidance to Laboratory organizations for developing their maintenance programs. It clarifies the maintenance requirements of the Operating and Assurance Program (OAP) and presents an approach that, while not the only possibility, can be expected to produce an effective maintenance program for research equipment belonging to the Laboratory's organizations

In many types of reactor fuel charging equipment, tongs or a grab, attached to a trolley, housed in a guide duct, can be used for withdrawing from the core a selected spent fuel assembly or to place a new fuel assembly in the core. In these facilities, the trolley may have wheels that roll on rails in the guide duct. This ensures the correct alignment of the grab, the trolley and fuel assembly when this fuel assembly is being moved. By raising or lowering such a fuel assembly, the trolley can be immerged in the coolant bath of the reactor, whereas at other times it can be at a certain level above the upper surface of the coolant bath. The main object of the invention is to create a fuel handling apparatus for a sodium cooled reactor with bearings lubricated by the sodium coolant and in which the contamination of these bearings is prevented [fr

Full Text Available Objetivos: Precisar los factores asociados al no uso del condón en adolescentes y jóvenes en el distrito de Chiclayo y describir algunas características de su conducta sexual. Diseño: Transversal, mediante muestreo polietápico. Lugar: Distrito de Chiclayo, Perú. Pacientes: Trescientos noventa y tres adolescentes y jóvenes, 196 de ellos mujeres y 197 varones. Intervenciones: Se encuestó a adolescentes y jóvenes, usando cuestionario autoaplicado. Para el análisis estadístico, se utilizó chi cuadrado, odds ratio y regresión logística. Principales medidas de resultados: Uso del condón. Resultados: La conducta sexual presenta diferencia en cuanto a la primera relación coital, siendo más precoces los varones. El uso adecuado del condón en los últimos seis meses fue mínimo en ambos sexos; la proporción de mujeres que refirieron que nunca lo habían usado fue muy alta. Conclusiones: El análisis multivariado mostró que los factores asociados al no uso de condón en varones fueron la falta de disponibilidad, disminución del placer y relación amorosa. En las mujeres, pérdida de romanticismo, interferencia con la relación sexual y uso de otro método anticonceptivo.

Full Text Available O uso abusivo de álcool por adolescentes é uma questão que preocupa os envolvidos com a educação, uma vez que as consequências desse fato podem gerar sérios prejuízos ao processo ensino-aprendizagem e ao adolescente que abusa. Com o objetivo de contribuir para o debate na busca de uma intervenção efetiva que possa ser utilizada, sobretudo nas escolas, procuramos detectar a possível relação entre uso abusivo de álcool e raciocínio moral. Para tanto, participaram alunos do ensino médio de uma escola pública, selecionados por meio da aplicação do AUDIT (The Alcohol Use Disorder Identification Test, que posteriormente foram entrevistados, conforme a Moral Judgement Interview (MJI proposta por Kohlberg. Os resultados obtidos revelam níveis e estágios morais aquém dos esperados. Concluímos que a prevenção pode ser pensada por meio da Educação Moral como uma proposta de intervenção efetiva contra o uso abusivo de álcool e outras drogas.

Development of Turbulence-Measuring Equipment

Hot wire turbulence-measuring equipment has been developed to meet the more stringent requirements involved in the measurement of fluctuations in flow parameters at supersonic velocities. The higher mean speed necessitates the resolution of higher frequency components than at low speed, and the relatively low turbulence level present at supersonic speed makes necessary an improved noise level for the equipment. The equipment covers the frequency range from 2 to about 70,000 cycles per second. Constant-current operation is employed. Compensation for hot-wire lag is adjusted manually using square-wave testing to indicate proper setting. These and other features make the equipment adaptable to all-purpose turbulence work with improved utility and accuracy over that of older types of equipment. Sample measurements are given to demonstrate the performance.
