Minimização do impacto ambiental com a técnica da retificação cilíndrica externa de mergulho de cerâmicas avançadas com a utilização da mínima quantidade de lubrificante (MQL) com adição água

Os fluidos de corte foram introduzidos nos processos de usinagem com a finalidade de melhorar as características de os processos tribológicos que estão sempre presentes nas superfícies de contato entre a ferramenta e a peça. Devido à multiplicidade de efeitos negativos do corte os fluidos, os resíduos produzem sobre a humanidade e o nosso meio ambiente, na produção moderna, tem havido uma crescente atenção com os cuidados para se selecionar os fluidos de forma eficiente que, além de eficiente deve ser compatível com o ambiente. Além dos requisitos habituais tribológicos de corte, os fluidos devem satisfazer as exigências do ambiente e atender a legislação ambiental imposta pelo Estado ou internacional ISO 14000. Dentre as alternativas, destaca-se a usinagem a seco e a utilização da mínima quantidade de lubrificação (MQL). Este último pode ser utilizado também com adição de água e, consequentemente, consumindo um volume menor de fluido de corte. Este trabalho pretende analisar o comportamento da técnica da MQL com adição de água no processo de retificação de cerâmicas avançadas, assunto pouco divulgado na literatura formal. Este estudo foi feito através da análise da avaliação do comportamento rugosidade do material retificado. Pela avaliação dos resultados obtidos, foi possível avaliar a técnica da MQL com água, interpretando-a como um método alternativo de usinagem menos agressivo ao meio ambiente, já que houve melhoria consistente da rugosidade do material pela técnica da MQL tradicional para a MQL com adição de água e com a limpeza da superfície de corte do rebolo.

Alterações antropométricas de lesados medulares após treinamento intervalado em natação

The goal of this study was to assess the alterations in some anthropometric measures of sedentary subjects with spinal cord injury after a swimming interval training program with the use of a lifejacket. The study included 17 male spinal cord injured subjects, divided into two groups: 11 subjects in the training group (TG) and 6 in the control group (CG).The protocol employed a stroke of breaststroke, in work periods of moderate to severe, and stroke in the back stroke in periods of active recovery. An anthropometric evaluation was applied before the application of the training protocol and another (reevaluation) after 8 weeks. In the TG, the results obtained after the swimming program showed a significant change (p < 0.05) in the supra-iliac (SICF) and in the triciptal cutaneous folds (TCF), arm and waist circumference measures, from the first evaluation to the reevaluation. In the CG there were no significant changes observed in any of the variables studied. When comparing the two groups after the swimming training program, the average of the variable SICFT in the TG was significantly lower than the average for the CG. Generally speaking, the out comings showed the swimming protocol efficiency in promoting desirable anthropometric changes in spinal cord injured subjects while a reduction of fatty tissue in the arms and abdominal region and an increase of muscular tissue in the upper limbs of those subjects also occurred.

A influência da orientação motivacional durante o treinamento de atletas iniciantes no tênis de campo

The motivation in the sport has been one of the most studied subjects nowadays, as much that some authors say that the motivation is the base for the success of an athlete, that is, the psychological part must also well be stimulated so that if it reaches the maximum level of concentration during a game it will obtains the expected result. Tennis is one of the sports that more grew in recent years, and together with this fast ascension also increased the number of interested in researching in this area of the Psychology of the Sport. The present study has as objective to begin the adaptation and validation of the interest scale and to analyze the influence of the motivational orientation of the athletes in the sportive performance of the Tennis through the application of scale Teosq – Task and Ego Orientation in Sport Questionnaire (DUDA, 1992), translated, adapted and validated by Hirota and De Marco (2006), where we can identify if the individual is guided for a task or an ego’s goal. This research was carried through in a situated academy of Tennis in the City of Cotia – SP – Brazil, counting on the participation of 20 citizens with age between 09 and 18 years of both the practicing sexes of Tennis. The calculation of the Alpha Coefficient of Cronbach was adopted as statistical method, in order to identify the trust worthy and validity of the instrument beyond the average of each orientation, to be able to verify the athlete’s motivational orientation. For the analysis of the results, the Alpha Coefficient was observed high, compared with previous studies, reaching values of orientation for the ego of 0,90, and 0,70 of orientation for task. They had been registered the following averages, 4,20 (+0,93) and 2,42 (+0,85), respectively of orientation for task and ego. With those results we can point that, the scale applied with the proposal to identify the motivational orientation of the athletes of Tennis, revealed efficiency, and trust worthy in its application, and in accordance with the results, the athletes are guided for task, revealing self-determination, selfconfident, more creative and they judge its success for the quality of the carried through work.

Efeitos do treinamento misto na promoção da saúde e sua interferência no perfil lipidêmico em indivíduos diabéticos tipo 2

Diabetes is a chronic disease that currently affects 171 million individuals approximately worldwide, with projection to reach 366 million people in 2030, increasing the prevalence of 2.8% in 2000 to 4.4%. The dyslipidemia is certainly one of the associated metabolic alterations most important, if we consider the main cause of death in Diabetes - the cardiovascular disease (CVD). One of the prevention and help factors in the Diabetes treatment and in the fall of associated complications is the physical exercise, which contributes to a better life quality to the diabetic. The main objective of the work was to evaluate the effect of a mixed physical exercises training program (aerobic/anaerobic with pause-active), including walking exercises, weightlifting and swiss ball, about possible changes in the blood lipid profile of adult individuals type 2 diabetics. The methodology used an experimental model of pre-test and post-test applied to the group. The data were first analyzed in a descriptive way for the normalization and the elaboration of averages and sample diversions. The sample was subdivided in two moments, being one pre and other post then weeks of training. After these procedures, the results of the values of the lipidic profile and glycemia were compared between the pairs pre and post training (test T Student, pair data), non-parametric. With the study, we can conclude that in despite of the low uptake of participants in the search, for reasons already cited, and the great age difference between them, the found results were partially satisfactory, because we achieved significant changes only in the glycemic variables, but we suggest future studies in the molds here proposed.

Verificamos que a grande maioria ainda encontra-se em fase inicial da aprendizagem dos estilos, onde a respiração e a autonomia no meio líquido ainda necessitam ser amplamente dominadas. Porém, a partir dos resultados é possível propor o início do processo de treinamento criando um vínculo entre a PCD e o professor/técnico e que sejam respeitadas as limitações e potencialidades dos participantes.

Efeitos do treinamento resistido sobre secreação de testosterona e cortisol: uma revisão bibliográfica

You can set the resistance training such as making a move against a resistance by performing a muscle contraction and generating a muscular adaptation. This form of training, was initially used only in training athletes aiming to strengthen and improve fitness. Some coaches did not give proper focus, as the increase in muscle mass would cause loss of flexibility and agility. But over time a huge evolution occurred within this area and the practitioners of resistance training are no longer just athletes, and reached the whole community, from young to elderly, being a physical activity that generates a large caloric expenditure and has several health benefits, improve the cardiovascular system and decreasing the amount of body fat in the body. Cortisol is a hormone secreted from a stressful stimulus to the body, secretion undergoes control of the hypothalamic-pituitary axis, which releases the hormone into the bloodstream andrenocorticotrópico, going to the adrenal cortex responsible for their release. This has catabolic function, acting in the metabolism of carbohydrates, proteins and lipids, as well as having an important effect antiflamatório. Testosterone is a steroid hormone cholesterol from being produced by the testicles in men, as in women is produced to a lesser extent in ovary and adrenal glands, has functions androgenic and anabolic. Androgen function is responsible for the development of male sexual characteristics, while on anabolic function operates in the growth of muscles and bones, influencing the development of the human body organs. Within the metabolic changes that occur in the resistance training testosterone plays an important role in protein synthesis, influencing the production of strength and / or power during exercise. The objective of this work is through a literature review to assess the effects of resistance training on the production of these hormones and the relationship between them

Comparação de dois métodos de quantificação de carga interna de treinamento em idosos

Tradicionalmente a prescrição de exercícios físicos é baseada unicamente em relação à carga externa. Entretanto, as adaptações fisiológicas em função do treinamento físico dependem da carga interna. Assim, a carga interna deve ser levada em consideração para uma otimização da prescrição exercícios físicos, principalmente durante exercícios em grupos que normalmente são utilizados para a população idosa. Porém, o envelhecimento parece acarretar em deteriorações na capacidade de interocepção, colocando em questionamento a validade de um dos principais métodos de quantificação da carga interna, o método que utiliza a percepção subjetiva de esforço (PSE). Desse modo, o objetivo do presente estudo foi comparar os métodos de quantificação da carga interna que utilizam a frequência cardíaca (FC), considerado o padrão-ouro para o presente estudo, com o método que utiliza a PSE na população idosa. Quarenta idosos praticantes de ginástica aeróbia (A) ou musculação (M) foram avaliados durante uma sessão de exercícios físicos. A determinação da carga interna pela FC e pela PSE foram realizadas através dos métodos de Edwards e de Foster, respectivamente. Os valores de carga interna (expressos em unidades arbitrárias) calculados pelo método da FC e PSE foram 69,4 ± 40,0 e 151,5 ± 83,5 para o grupo M e 73,3 ± 37,1 e 134,7 ± 41,6 para o grupo A, respectivamente. O valor de carga interna para os dois grupos em conjunto foi de 71,3 ± 38,2 pelo método da FC e de 143,1 ± 65,7 pela PSE. A relação entre os métodos foi determinada usando-se o coeficiente de correlação de Pearson para todos os participantes em conjunto (T), assim como para os grupos M e A. As correlações encontradas foram de r = 0,33 (p < 0,05) para T, r = 0,37 (p = 0,11) para M e r = 0,32 (p = 0,17) para A. A moderada correlação obtida coloca em questão a utilização do método da PSE para a quantificação de carga interna...

Co-digestão anaeróbia de dejetos de suínos, níveis de inclusão de óleo de descarte e microrganismos lipolíticos redução do impacto ambiental

The objective of this work for evaluating the potential of biogas and methane productions and still and reductions in levels of total solids (TS), volatile solids (VS) and neutral detergent fiber (NDF) of the co-digestion anaerobic digestion in digesters fed with swine manure plus disposal of oil and lyophilized microorganisms. For assay development substrates were prepared containing 4% TS, consisting of swine manure, disposal oil (the proportions 8, 10 and 12% oil content in relation to the substrate TS), lyophilized microorganisms (Biol-2000 ® - concentrations of 10 g/m3 and 15 g/m3 ), water for dilution of this waste and inoculum for batch digesters supply. There was no significant difference with respect to reductions in TS, VS and NDF constituents, providing very significant reductions in average 54.14; 62.79 and 49.16% respectively. Regarding the potential of biogas production, the highest yields occurred in digesters supplied with 10% oil and 15 g/m3 of Biol®, being 0.43 and 0.54 L of biogas per kg of TS and VS added, respectively, similar results were found when assessed the potential for methane production, with higher values (0.22 and 0.27 L of methane per kg of TS added and VS, respectively) obitidos the same treatment. The inclusion of 15 g/m3 in Biol® substrate composition containing swine manure and 10% of oil improves the yields of biogas and methane.
