Influência da música preferida no desempenho e estados afetivos de idosos durante exercício de intensidade auto-selecionada

Low adherence to physical exercise programs is a factor that contributes to the high rates of physical inactivity worldwide. In this sense, strategies to improve the affective responses during exercise are used to impact adherence, as the use of music and self-selected exercise intensity. Despite the benefits of these strategies, there are few studies involving the combination of both (self-selected intensity and music), especially in the elderly population. Thus, the aim of this study was to investigate the influence of music on performance, ratings of perceived exertion (RPE) and on affective and motivational responses of elderly during walking exercise with self-selected intensity. Eleven elderly performed walking sessions on an athletic track in three conditions: without music, with motivational music and with oudeterous music. RPE, mood states, motivation, affective responses, session RPE and attitudes related to the experience of exercise were evaluated. Results demonstrated that both motivational and oudeterous music improved affective responses and decreased RPE. However, only the motivational music condition showed an effect on distance walked, the only presenting a consistent increase in distance. Therefore, it is concluded that the use of music, particularly motivational music, besides increasing the distance walked, reduces RPE and increase pleasure of the elderly during the exercise. Such strategy, in addition to potentially impact adherence positively, can lead to greater benefits and physical adaptations related to the training in the long term

Motivação e personal trainning

Currently, health is one of the issues of concern of society. Health can be understood as a direct link between the practice of regular exercise and quality of life. Within this course of reasoning, comes the role of physical education professional. In this perspective, we have the Personal Trainer. Personal Trainer is the professional who makes exercise prescription, individually, with improvement goals fitness and others. This professional is someone trained in Physical Education and has qualification and training for that function. Thus, the aim of this study is to identify the reasons why the practitioners of physical exercise to train under the supervision of a Personal Trainer. To achieve the above goal was accomplished, a review of major studies on the subject. Thus, this work it is a research bibliography. On the literature review it is evident the professional demand due to a cultural change and, moreover, the need for and accessibility of this professional, the Personal Trainer. In addition, the adhesion of reasons in class Personal Trainer to give the competence of the professional in achieving goals and objectives of the student, respecting the individuality and motivation of each student, reasons that may be intrinsic or extrinsic. In Motivation respect, it is clear the need for deepening of the term, to be able to adequately meet the student

Tipo de cimentação em materiais duros do perfil de alteração da mina de fosfato da Anglo American, Catalão-GO

One of the main challenges in the mining sector at present, related to the optimization of mineral assets, consists in to find the best proportion of each geological material to be mined and homogenized to ensure high productivity and stability in ore processing plants. The stability of a mineral processing plant is factor for achieving operational excellence, as a stable performance of the plants ensures economy and adherence to financial planning businesses. Is already well Know that the feed rate of the processing plants is dependent on the hardness and quality of the ore. Therefore, the ore behavior predictability is the solution to ensure the stability of mineral processing plants. This work was developed in Anglo American Phosphate Brazil Ltda., at the Fazenda Chapadão Phosphate Mine, located in the southeastern portion of the state of Goiás, in the municipalities of Catalão and Ouvidor. The phosphate ore is the result of supergene apatite concentration in the weathering profile of the alkaline ultramafic phlogopitized rocks, intruded by foscoritic and carbonatitic rocks series. The weathering profile has about 100 meters thick and is divided into three basic types, from top to bottom, coinciding with decreasing intensity of weathering: oxidized ore, micaceous ore and weathered rock. In each portion of this weathering profile, mainly near the contacts between these three divisions, are hard materials, cemented by minerals such as apatite, quartz, goethite, monazite and barite. The different features presented by these materials makes to be vital the correct identification, quantification and location of different hard materials in the mine area, to maximize its use. The main objective of this study was to define the type of cementation of hard materials which predominates in each portion of the weathering profile in the mine, as well as their relationship with the protolith. The work involved geological mapping, channel sampling...

Avaliação histológica e videolaparoscópica de ligaduras dos pedículos ovarianos realizados com mononáilon agulhado ou abraçadeiras auto-estáticas de náilon em cadelas submetidas à ovariossalpingohisterectomia pela técnica do gancho

A procriação excessiva de cães e gatos no ambiente urbano é um problema de saúde pública e de bem estar animal. Para se desenvolver campanhas de controle populacional necessita-se de protocolos cirúrgicos seguros, rápidos e de baixo custo. A abraçadeira auto-estática de náilon aparentemente se encaixa neste perfil. Objetivou-se avaliar por laparoscopia e histologia, a reação tecidual após a ligadura dos pedículos ovarianos com abraçadeira auto-estática ou mononáilon agulhado na ovariosalpingohisterectomia em 18 cadelas. Após 60 dias do procedimento cirúrgico não foi observada pela laparoscopia nenhuma aderência ou alteração macroscópica e a histologia dos fragmentos dos pedículos ovarianos demonstrou que a resposta tecidual não diferiu entre os métodos, revelando que a abraçadeira auto-estática pode ser usada como método de ligadura dos pedículos ovarianos de cadelas submetidas à ovariosalpingohisterectomia.

Uso de antibióticos convencionais e antimicrobianos a base de lúpulo no controle da infecção bacteriana em fermentação alcoólica

The aim of this work was to compare the efficiency of conventional antibiotics in relation to hop-based antimicrobials, in industrial-scale bioethanol production. The comparison was made by calculating the lactic acid bacteria population reduction in two consecutive fermentation cycles. To conduct the experiment, it was used five treatments (three conventional antibiotics: Kamoran WP, Corstan and Alcapen 1030, and two hop-based antimicrobials: BetaBio and IsoStab). The samples were collected in the fermentation vat. In order to quantify the initial lactic acid bacteria population, a sample was collected at the end of the fermentation process (wine) before the treatment with antibiotics or antimicrobials, and to determine the final population, another sample was collected at the end of the fermentation process (wine) after the treatment with antibiotics or antimicrobials. The experiment was completely randomized and the statistical analysis was performed through analysis of variance (ANOVA) for data processed using the equation y’ = . After the data transformation, the Levene's test was applied to verify data adherence to normal distribution, and the averages were compared through Tukey’s test at 5% probability. The results showed that the hop-based antimicrobials (IsoStab and BetaBio) can be used to substitute the conventional antibiotics (Kamoran, Alcapen and Corstan), since there was no statistical difference between the treatments.

Previsão de demanda de veículos automotores através do modelo de regressão linear múltipla

This study aimed to model a equation for the demand of automobiles and light commercial vehicles, based on the data from February 2007 to July 2014, through a multiple regression analysis. The literature review consists of an information collection of the history of automotive industry, and it has contributed to the understanding of the current crisis that affects this market, which consequence was a large reduction in sales. The model developed was evaluated by a residual analysis and also was used an adhesion test - F test - with a significance level of 5%. In addition, a coefficient of determination (R2) of 0.8159 was determined, indicating that 81.59% of the demand for automobiles and light commercial vehicles can be explained by the regression variables: interest rate, unemployment rate, broad consumer price index (CPI), gross domestic product (GDP) and tax on industrialized products (IPI). Finally, other ten samples, from August 2014 to May 2015, were tested in the model in order to validate its forecasting quality. Finally, a Monte Carlo Simulation was run in order to obtain a distribution of probabilities of future demands. It was observed that the actual demand in the period after the sample was in the range that was most likely to occur, and that the GDP and the CPI are the variable that have the greatest influence on the developed model

Análise das perturbações de qualidade de energia em sistemas de distribuição e a adequação as tendências regulatórias do PRODIST

The public consultation n° 018/2014, for review the Module 8 of Procedures of Electricity Distribution (PRODIST), conducted by National Agency of Electric Energy (ANEEL), aims to improve the regulation of power quality, considering the phenomena harmonic distortion, voltage unbalance, voltage fluctuation and short term voltage variation. These regulatory changes impact in the way of analysis and treatment, of power quality disruption, by the electricity distribution. The developed work makes a study about the applications of these new regulatory requests and hopes to contribute with a better understanding. Through power quality measurements, in distribution substations, with different load profiles (industrial, urban and rural), was obtained a real view of the system, under the aspect of power quality, to evaluate the regulation adherence to the current version and proposed. In this case study, although being in accordance with the current methodology, happened a transgression of propose. With a comparative analysis, was possible to identify some phenomena that were more flexible in the proposed revision and others with more severe monitoring

Citotoxicidade de membranas à base de ácido polilático e poli-ε-caprolactona com a incorporação de fosfato de lantânio e oxiapatita dopada com lantânio

Desde a antiguidade, enxertos e membranas são estudados para promoverem um reparo ósseo otimizado. O reparo ósseo consiste na reabsorção do tecido necrosado e de seu coágulo, juntamente com um processo inflamatório que libera fatores de crescimento que irão reparar o osso danificado. Em algumas situações, o osso lesionado não tem a capacidade de se auto reparar, portanto, são necessárias intervenções cirúrgicas para inserir um enxerto ósseo. Entretanto, há uma grande dificuldade em se encontrar um material que forneça os fatores necessários para o crescimento ósseo. Para isso, foram confeccionadas membranas à base de ácido polilático e poli-ε-caprolactona (PLC) (Purasorb: PLC 7015 - Purac, Holanda), com a incorporação de fosfato de lantânio (PLC/LaPO4) e oxiapatita dopada com 20% de lantânio (PLC/La20OAP) pelo Instituto de Química de Araraquara, UNESP. Assim, o objetivo do presente estudo foi avaliar a citotoxicidade desses materiais por meio dos testes XTT e sobrevivência clonogênica. Os eluatos foram preparados com as membranas citadas de acordo com a ISO 10993-12. O cloridrato de doxorrubicina foi utilizado como controle positivo para ambos os testes. Como Controle Negativo (CN) foram utilizadas somente as células CHO-K1 (sem a ação de qualquer tratamento) por 24 horas. Os eluatos foram mantidos em contato com células CHO-K1 por 24 horas. Como os dados apresentaram aderência à curva normal, foi aplicada a análise de variância (ANOVA) one-way, seguido dos testes de Tukey e Dunnett (p<0,05). Verificou-se que os materiais testados não demonstraram absorbância estatisticamente diferente em relação ao CN (p>0,05; Dunnett - XTT) e também não causaram comprometimento na capacidade proliferativa das células (p>0,05; Dunnett - Sobrevivência clonogênica). Assim, pode-se concluir que as amostras de PLC, PLC/LaPO4 e PLC/La20OAP não apresentaram citotoxicidade em células CHO-K1.
