Group analysis method for fission track thermochronology

A methodology to obtain ages and thermal histories of sets of apatite samples from localities with geologically compatible characteristics is described. A methodology exploring the fact that samples with similar geological characteristics should present the same thermal history is proposed. This approach can contribute for the obtainment of more conclusive results by analysing fewer samples than it is necessary when the samples are individually analysed. In order to determine the ages, we use the absolute neutron dosimetry through thin films of natural uranium along with lambda(f) = 8.46 x 10(-17) a(-1). As an example of application of the proposed methodology, we analyse samples collected in a Brazilian region, Sao Francisco Craton, which experienced low tectonic activity. (C) 2008 Elsevier Ltd.

Thermoeconomic analysis method for optimization of combined heat and power systems

This article presents an thermoeconomic analysis of cogeneration plants, applied as a rational technique to produce electric power and saturated steam. The aim of this new methodology is the minimum exergetic manufacturing cost (EMC), based on the Second Law of Thermodynamics. The decision variables selected for the optimization are the pressure and the temperature of the steam leaving the boiler in the case of using steam turbine, and the pressure ratio, turbine exhaust temperature and mass flow in the case of using gas turbines. The equations for calculating the capital costs of the components and products are formulated as a function of these decision variables. An application of the method using real data of a multinational chemical industry located in São Paulo state is presented. The conditions which establish the minimum cost are presented as finals conclusions.

Thermoeconomic analysis method for optimization of combined heat and power systems - part II

In this paper, a thermoeconomic functional analysis method based on the Second Law of Thermodynamics and applied to analyze four cogeneration systems is presented. The objective of the developed technique is to minimize the operating costs of the cogeneration plant, namely exergetic production cost (EPC), assuming fixed rates of electricity production and process steam in exergy base. In this study a comparison is made between the same four configurations of part I. The cogeneration system consisting of a gas turbine with a heat recovery steam generator, without supplementary firing, has the lowest EPC. (C) 2004 Published by Elsevier Ltd.

Gene Content Analysis of Sugarcane Public ESTs Reveals Thousands of Missing Coding-Genes and an Unexpected Pool of Grasses Conserved ncRNAs

Sugarcane is the most important crop for sugar industry and raw material for bioethanol. Here we present a quantitative analysis of the gene content from publicly available sugarcane ESTs. The current sugarcane EST collection sampled orthologs for ~58 % of the closely-related sorghum proteome, suggesting that more than 10,000 sugarcane coding-genes remain undiscovered. Moreover the existence of more than 2,000 ncRNAs conserved between sugarcane and sorghum was revealed, among which over 500 are also detected in rice, supporting the existence of hundreds of conserved ncRNAs in grasses. New efforts towards sugarcane transcriptome sequencing were needed to sample the missing coding-genes as well as to expand the catalog of ncRNAs. © 2012 Springer Science+Business Media, LLC.

Checklist de cirurgia segura: análise da segurança e comunicação das equipes de um hospital escola

Este estudo teve como objetivo aplicar o checklist de cirurgia segura, da Organização Mundial de Saúde, nas especialidades cirúrgicas de um hospital escola, e verificar a opinião das equipes sobre a influência da aplicação do checklist na segurança do processo cirúrgico e da comunicação interpessoal da equipe. Trata-se de um estudo de campo, descritivo, analítico, com abordagem qualitativa, realizado no centro cirúrgico de um hospital-escola. Para a coleta de dados, foi aplicado o checklist num total de 30 cirurgias, conduzido pela pesquisadora, em três etapas, e, a seguir, um componente da equipe cirúrgica foi convidado a participar do estudo, assinando o TCLE e respondendo a questões norteadoras. Para organização e análise dos dados, recorremos ao Método de Análise de Conteúdo de Bardin. Os sujeitos não perceberam mudanças na comunicação interpessoal com o uso do checklist, porém, indicaram que o uso proporcionou mais segurança ao procedimento. Adaptações ao checklist foram sugeridas.

Qualidade de vida na terceira idade: um conceito subjetivo

Tendo-se em conta a expectativa de vida cada vez mais alta, vários estudos têm sido desenvolvidos de modo a contribuir para a melhoria da qualidade de vida na terceira idade. Objetivou-se conhecer a opinião dos idosos de um município de porte médio do interior paulista sobre o que é qualidade de vida, através de uma pergunta aberta que foi incluída como parte de um inquérito populacional sobre estilo e qualidade de vida. A análise da referida questão foi realizada através do método de Análise de Conteúdo. Posteriormente calcularam-se as freqüências das categorias obtidas, agrupadas segundo o método de Ward, e em seguida os idosos foram agrupados segundo o método de k-médias. Os resultados indicaram a existência de três grupos de idosos segundo sua definição de qualidade de vida: o primeiro valorizou a questão afetiva e a família; o segundo priorizou a obtenção do prazer e conforto; o terceiro poderia ser sintetizado como o idoso que identifica a qualidade de vida colocando em prática o seu ideário de vida. Sugere-se que, na implementação de ações, se objetive melhorar a qualidade de vida do idoso, levando-se em conta as magnitudes e as diferenças de cada grupo.

O trabalho do enfermeiro na vigilância à saúde da criança sob o olhar da gestão da Atenção Básica à Saúde

This study aimed at apprehending and analyzing the perspective of Primary Health Care managers concerning nurses’ work in Children’s Health Surveillance in a city in São Paulo state. The study population consisted of eight professionals from different professional categories with direct activity in the city’s management of the population’s Health Surveillance. It is a descriptive, qualitative study. Data were collected by means of recorded semi-structured interviews. The framework used for data analysis was the thematic Content Analysis Method. The results were systematized into three themes: 1- Managers’ conceptualizations concerning Children’s Health Surveillance and its application in practice; 2- Managers’ perspectives concerning nurses’ work in Children’s Health Surveillance; 3- Qualification of Children’s Health Surveillance under the view of the municipal management. The conceptualizations concerning Children’s Health Surveillance that were apprehended showed to be convergent as they indicated this model’s appropriateness to identify and prioritize children’s care in vulnerability conditions in the territory where they live. However, some managers did not include, in their statements, health promotion aspects as one of the cornerstones of their managerial action. Nurses were considered to be fundamental in the Children’s Health Surveillance process due to their competencies and responsibilities undertaken in this health provision level. The main difficulties for adequate implementation of Children’s Health Surveillance in Primary Health Care and the proposal to overcome them were pointed out. It was concluded that, under the managers’ perspectives, nurses can greatly contribute to Children’s Health Surveillance in Primary Health Care as members of the health care team; however, to that end, they need professional qualification, structural conditions and institutional support with that regard

Checklist de cirurgias da OMS: análise da segurança e comunicação da equipe cirúrgica de um hospital escola

WHO has launched the “Safe Surgery Saves Lives” program with the purpose to reduce damage to surgical patients and define safety standards specifically in order to reduce such patients’ morbi-mortality by providing surgery teams and hospital managers with orientation about the standards of safe surgery and a uniform service evaluation instrument for national and international surveillance. Hence, this study aimed at applying the WHO safe-surgery checklist to the surgical specialties of a university hospital and evaluating the team’s opinion about the influence of its application on the safety of surgical process and on the team’s interpersonal communication. It was a descriptive, analytical, qualitative field study conducted in the surgery facilities of a university hospital in a public establishment in São Paulo state. The checklist was applied to eight surgical specialties, resulting in a total number of 30 surgeries. Its application was conducted by the researcher in three phases: Sign in, Time out, Sign Out. Next, one member of the surgery team was invited to voluntarily participate in the study by signing an informed consent form and answering guiding questions. Thirty members of the surgery team participated in the study. Bardin’s Content Analysis Method was used to organize and analyze the data. As regards the safety provided by the checklist, the following thematic categories emerged: “It reduces risk and possible complications”; “It standardizes conducts and reviews safety steps”; “It allows for better understanding of the process”; and “It provides safety to the team as a whole”. The category “It is not included in the institution’s routine” emerged from the subjects’ statements when they understood that, in this form, the checklist does not provide safety to surgical procedures. As regards communication, two thematic categories emerged: ...(Complete abstract click electronic access below)
