Nine swines of the White Large race were used for study of the process of bony repair after osteotomy with rotating instruments of low and high-speed, with and without liquid refrigeration. The authors observed, through double blind histopathological analysis, that in every analyzed operative time, the bony repair was processed more appropriately when the osteotomies were accomplished with liquid refrigeration. In the final postoperative times, of fourteen and twenty-eight days, the best results of bony repair were observed in the osteotomy accomplished with drills of low rotation and with liquid refrigeration, while in the postoperative time of seven days, the results of the bony repair of osteotomy accomplished with drills of high rotation and with liquid refrigeration they were better. The authors consider, still, that the process of bony repair in swine display larger proximity in the histological pictures among the studied variables, when compared with other biological models. As most of the works told in the literature it refers the use of dogs, the authors consider that the present work guarantees your importance in the sense of looking for a closer model of the man.

Sodium cyclamate contents in the widely consumed low calorie soft drinks were determined. Low calorie soft drinks made from cola, guarana, orange, lemon and grape were analyzed following the technique described by Sjörberg and Alanko (1987), with some modifications. The methodology recovery assays were carried out at three spiked levels, and the average recovery of 92.5% and 110.3% were found in cola and guarana, respectively; and the relative standard deviation was of 3.7%. The average sodium cyclamate contents ranged from 27.1 ± 1.1 (cola A) to 127.3 ± 1.5 mg.100 mL-1 (lemon B), indicating that the acceptable daily intake of the sweetener can be easily exceeded after drinking low calorie beverages. All of the analyzed low calorie soft drinks showed sodium cyclamate contents higher than those stated on the label, ranging from 12.9% (cola A) to 19.0% (lemon B). Among 18 low calorie soft drinks analyzed, only four showed the average sodium cyclamate contents in accordance with the maximum limit permitted by Brazilian legislation, that is 40 mg.100 mL-1 of beverage; and in other samples the sweetener exceeded ranging from 74.8% (orange) to 218.3% (lemon B) above of the limit permitted.

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profi le of the elderly who also used walking as a means of getting around.

Introdução: Na sociedade contemporânea costuma-se associar Design ao consumo de luxo, entretanto o design encontra-se aplicado a todos os objetos, do automóvel ao clips, todavia o Design parece estar sempre atrelado à sociedade de consumo, à indústria a serviço do capital e das relações de subordinação e expropriação a ele atrelado. Assim faz-se necessário despertar no aluno do curso de Design a possibilidade da aplicação de seu conhecimento a serviço de uma sociedade mais democrática e solidária, de não apenas produzir a serviço do capital, mas pensar de forma mais abrangente, considerando o bem comum. Objetivos: O Labsol, desde 2007, procura: Otimizar, revitalizar e qualificar a produção artesanal através dos conceitos de ecodesign, sustentabilidade e economia solidária, tendo em vista a auto sustentabilidade das comunidades produtoras. Desenvolver projetos e ações que promovam encontros entre o Design e o patrimônio cultural do artesanato. Preocupar-se com a qualificação do produto artesanal e sua inserção no mercado, tendo em vista a auto sustentabilidade das comunidades produtoras. Métodos: A formação dos integrantes do LabSol é continua e baseada em três conceitos fundamentais: sustentabilidade, economia solidária e eco design. As ações se dão a partir do convite de uma comunidade de artesãos na perspectiva da qualificação estética ou produtiva de seus trabalhos e a melhoria da geração de renda. Utiliza-se o método empírico, de caráter prático, através de estudo de caso. Em uma visita aprende-se métodos e técnicas utilizados pela comunidade, e de volta à sede, faz-se revisão bibliográfica e utiliza-se a metodologia do projeto em design para melhoria das técnicas produção, o redesenho de produtos e a geração de novos objetos de design. Construídos modelos e protótipos e avaliado seu potencial de comercialização são submetidos a aprovação da comuni-dade através de oficinas. O diferencial no trabalho do LabSol se dá na maneira que os projetos são entregues aos grupos. Entende-se todo o processo como um aprendizado de mão dupla, da troca de saberes, onde os membros do laboratório aprendem da comunidade dados de sua cultura e de seus modos de fazer, em contrapartida novos produtos são levados de volta a comunidade, entendidos como mais um dado cultural posto a disposição da comunidade podendo ou não ser por ela incorporado. Resultados: Com mais de 20 grupos atendidos, e centenas de produtos de eco design, as ações o LabSol resultam na pesquisa de eco design, materiais, técnicas, métodos e de novas tecnologias sociais, gerando um número significativo de publicações e exposições de divulgação. Tem recebido graduandos de relações públicas e engenharia de produção, a junção de saberes tem permitido um aprimoramento na qualidade de atendimento ás comunidades.

Sustainability suggests a new social organization required for human survival. The aggravation of environmental problems arising by population growth, industrialization, disorderly and unconscious consumption of Human Being, induces us to think about how to stop these problems. Recycling presents itself as a means of stopping environmental destruction and as a way to increase the family income of the poorest society existing in our globalized world. This article suggests a research on recycling being carried out as a means of livelihood.

Work is one of the fundamental elements for building the human identity. In this way, the Career Guidance (CG), whose character is reflective, increases choice processes, and can favour further relations from students to work. This article treated about university extension actions guided to four groups of young apprentices, whose families have low scholarity and income. Besides the synthesis of the objectives and methods of the project, they were transcripted students' narratives about the benefits they achieved, and the conclusions of Psychology students who were envolved. The qualitative comprehension of those data allowed to consider that the CG activities widened the self-knowledge, the choice and development possibilities of the participants. It is suggested the expansion of these practices.

This paper presents a technique to add flexibility in the control of power electronic converters. The power converter can function as an active power filter, as a local power source interface or perform both functions i. e. mitigate current disturbances and inject power into the grid simultaneously, configuring it as a multifunctional device. The main goal is to extract the full capability of the grid connected power electronic converter to achieve maximum benefits. To achieve this goal, the orthogonal current decomposition of the Conservative Power Theory is used. Each orthogonal current component is weighted by means of different compensation factors (k_i), which are set instantaneously and independently, in any percentage by means of the load performance factors (λ_i), providing an online flexibility in relation to compensation objectives. Finally, to validate the effectiveness and performance the proposed approach, simulations and experimental results are presented.

The implementation of residue selective collection has brought to the city of Sao Manuel an incalculable benefit. It brought a better life for a group of adults and children that lives in a humanitarian condition of extreme poverty. These people live in an open-air dump, disputing the remains found in fifteen tons of garbage that are deposited at the site almost every day.The objective of this paper is to present thecollectors annual income profile and the volume of solid waste collected.To present these factors, the total and fractionated amount according to their material items, collected since the creation of the Association in February 2003 until December 2008, were considered., In addition,the social gains were enumerated. These factors were developed from a theoretical base for municipal solid waste involving environmental, social, and financial concepts. Based on these results it was found that the ACAPEL income value was above the average of other income indicators of the population analyzed, besides the social value enhance that the creation of the Association brought to the people who work there.
