Translation, cultural adaptation to Brazil and validation of the venous leg ulcer quality of life questionnaire (VLU-QoL-Br)

Objetivo:traduzir o instrumento Venous legulcer quality of life questionnaire (VLU-QoL), adaptá-lo culturalmente para o português do Brasil e validá-lo com pacientes do Hospital das Clínicas da Faculdade de Medicina de Botucatu (FMB) da Universidade Estadual Paulista (Unesp). Métodos:o questionário foi traduzido por um tradutor profissional e por dois dermatologistas especialistas na área de úlceras venosas (UV), sendo reformulado em reunião com os três tradutores. O constructo (VLU-QoL-Br) foi submetido a pré-entrevista com 10 portadores de UV para a adaptação da linguagem. Posteriormente, foi aplicado em pacientes do HC-Unesp, e como teste-reteste para verificação de sua reprodutibilidade. Resultados:foram avaliados 82 pacientes, sendo 56 (68%) do sexo feminino. A idade média foi de 67,3 anos. O questionário foi traduzido, adaptado e aplicado aos pacientes. O constructo apresentou alta consistência interna (alfa= 0,94) e adequada correlação item-total. Quando avaliados os 32 retestes, observou-se correlação intraclasse para concordância de 0,78 (p < 0,01), indicando boa reprodutibilidade do constructo. A análise fatorial confirmatória corroborou as dimensões do questionário original: atividades, psicológico e sintomas. Escores do VLU-QoL-Br se associaram, independentemente, à área total das úlceras e a menor escolaridade dos sujeitos (p < 0,01). Conclusão:a tradução, a adaptação e a validação do questionário VLU-Qol-Br demonstrou boa performance psicométrica, permitindo seu uso clínico no Brasil. É importante avaliar seu desempenho em outras regiões e em diferentes amostras de indivíduos.

A circulação do discurso da Amway: do controle à prática discursiva

In this paper, we intend to contribute to the debate about the circulation of the discourses. To do that, we analyze aspects regarding the circulation of Amway's discourse, a North-American network sales company that has been working in Brazil for a while. Precisely, we analyze the conditions of this circulation at the time it was more intensively, ie, in the 90s, when there were thousands of people in several parts of the country selling the company's products or consuming them. This study has been based on French Discourse Analysis with focus on both Michel Foucault's insights on the control mechanisms of discourse and Maingueneau's reformulated notion of discursive practice. The analysis reveals that Amway's discourse displays features of a doctrine, and, as a discursive practice, it cannot be conceived of as separated from the subjects who convey it, nor from its hierarchical organization, nor from the events that the company promotes and those which are promoted under its name. In these terms, the analysis shows how the discourse is not only a set of texts, but also concerns to the institutional network related to the social group that the enunciation of discourse presupposes and makes it possible.

Petroleum products biodegradation profile similarity evaluated by F test comparison of weekly CO2 production

Strategies applied to bioremediation contaminated environments are necessary to identify limitations towards biodegradation and to predict remediation performance and thereby rule out technologies that may be inappropriate for the clean-up of the substances of concern. Respirometry applied to bioremediation offers a series of advantages for obtaining CO2 production data when compared to other procedures. It was possible to determinate information regarding the atmosphere's CO2 concentration inside a respirometer containing petroleum products. Afterwards, the CO2 data obtained underwent an in depth statistical analysis by F test. There are some noticeable biodegradation similarity among some substances, such as weathered motor oil and gasoline. Such data provides reliability when revealing important information about how the biodegradation processes happens in those residual oils.

Estudo e modelagem 3D de um cabeçote para um motor monocilíndrico, 400cc, 4 T

The cylinder head contains the combustion chamber for the air-fuel mixture and the intake and exhaust valves, the valve guide and the valve seat. The cylinder head also is a support for the camshaft and valve rocker. The holes where the spark plugs are connected are designed to fit the better place in the combustion chamber. The cylinder heads often are manufactured using materials such as aluminum and cast iron. The cooling fins located in the outside of the cylinder head are designed for a good heat transfer and therefore their dimensions and positioning are important. This work aims the calculation for a cylinder head to be installed in a 400 cc displacement, gasoline powered, four stroke, single cylinder engine. According to the displacement it will be analyzed the combustion chamber, the intake and exhaust valves, as well as the camshaft and rocker arms. This also a work to help to accomplish the design of a single cylinder engine, where the alternatives parts, cylinder block and crankcase are all already machined and assembled in this campus

Rerrefino de óleo lubrificante usado

The lubricant oil used in engines of internal combustion must be, periodically, changed. Its mainly function in the engines is to reduce the friction between the pieces, but its presence also promotes the cleanness and the refrigeration of the equipment. These attributions, at the end of some cycles of operation, make the oil to be dirty, that is, full of contaminating substances such as water, gasoline, diesel, additives, oxidized hydro-carbons and rests of metals, not being recommended, therefore, its discarding in the environment. Thus, all the used lubricant oil that leaves the automobiles engine has been thrust, waiting for a solution. The pollution generated by the discarding of a ton of used oil per day in the soil or in the rivers is equivalent to a domestic sewer of 40 thousand of people. The indiscriminate burning of the used lubricant oil generates significant emissions of metallic oxides, besides other toxic gases, like the dioxin and sulphur oxides. In this context, the mean objective of this essay was to effectuate the rerrefine of the used lubricant oil, aiming the increase of its life cycle and consequently contributing for the reduction of the environmental pollution. According to the used process, it was possible to get a rerrefine oil, of good quality, which physicistchemistries properties are in compliance with the norms of NBR and ASTM
