The world’s population is having more and more difficulties in performing their daily activities and leisure, becoming, this way, more sedentary. Sedentary lifestyle can be considered as a reduction or as a lack of physical activity, less than the minimum volume suggested by the World Health Organization (WHO). Physical activity changes the behavior and some environmental acts. This study aimed to identify the NAF of students in the area of Physical Education and Healt Nursing and compare it with identified students’ levels non-health areas, being Production Engineer and Pedagogy. Aimed to correlate the found volume of 15 participants, with the state of cardio respiratory fitness (VO2max). The study included 125 students of both sexes from a university located in São Paulo state country. We conducted a cross-sectional study from August to October of 2012. For the initial test of the volume of physical activity we used the International Physical Activity Questionnaire (IPAQ) long version. In order of assessing cardio respiratory fitness, the Katch and McArdle seat test (1981) was used. Data were analyzed according to Physical Activity Level (PAL) presented by the university students in sessions 1, 2, 3, 4 of the IPAQ, and 15 students’ results were correlated with VO2max test. From these results we can say that: IPAQ session 1 showed that students in the health area are statistically superior to the non-health students area to the high-active classification. In session 2 the results were significant and superior to the health area and very active in sedentary classification. The session 3 results were very similar to session 1, showing that the health area as high-active with statistics differences. In session 4 we can see very significant results for health area in high-active areas and irregular actives. A total of 4 sessions found significant results for very active and sedentary. When was the attempt of association between levels 15 participants found the IPAQ long version and test bank VO2max, the results showed no significant association. The results of this study show a need for policies to encourage physical activity in the University environment, emphasizing a greater need for students who do not work in healthcare.

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

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

Landscape is the result of interaction between tectonic, weathering and pedogenetic processes, so it is necessary to understand the morphogenesis and relate it to the landforms and landscape. Therefore, this project comprises a geomorphological characterization of some areas associated with the fault zones of Taubaté Basin, at the surroundings of the cities from São José dos Campos to Taubaté SP, emphasizing the Quaternary landscape evolution, where the normal faults played an important role in controling and they were originated, mostly, from the reactivation of Precambrian fault zones by tectonic action. The rift valley scenario is highlighted in the region, identifying the sharp relief from the basin boundary, featuring both Serra do Mar and Serra da Mantiqueira, and a central depressed area where the Taubaté Basin is located. Deforming or modifying basin features are identified, promoting the rearrangement and conditioning of the drainage network and relief, which indicates the presence of morphostructures, conducting to the deduction of a late tectonic process

O fungo Colletotrichum gossypii var. cephalosporioides, agente causal da ramulose do algodoeiro, é transmitido pela semente que se constitui em uma das mais importantes fontes de inóculo inicial e de introdução da doença em áreas indenes. Para que se possa identificar sua presença em lotes de sementes, é importante que se empreguem métodos de detecção rápidos e seguros. O mais empregado é o do papel de filtro, que se baseia na avaliação de sinais do patógeno desenvolvidos sobre as sementes, seguida da sua identificação morfológica. O método apresenta a desvantagem do crescimento das plântulas no período de incubação das sementes que pode favorecer o desenvolvimento de outros fungos e prejudicar a caracterização do patógeno. Para minimizar este problema vem sendo empregada a técnica da restrição hídrica. O presente trabalho teve como objetivo avaliar o efeito de três solutos em dois potenciais osmóticos, comparados ao tratamento padrão de água destilada, ao congelamento e ao 2,4 D, sobre a germinação, comprimento da radícula e detecção do agente causal da ramulose, durante o teste de sanidade. Os solutos Manitol e NaCl foram mais eficientes em inibir a germinação e favorecer a incidência do patógeno no potencial osmótico de -0,8 MPa. O KCl mostrou-se eficiente em inibir a germinação nos dois potenciais osmóticos testados, -0,6 e -0,8 MPa, porém reduziu a incidência do patógeno no potencial de -0,8 MPa. Os solutos Manitol, nos potenciais osmóticos de -0,8 e -0,6 MPa e o NaCl no potencial osmótico de -0,8 foram eficientes em reduzir o comprimento da radícula, sem interferir negativamente nos níveis de detecção de C. gossypii var. cephalosporioides, podendo ser recomendados para uso em análises sanitárias de rotina.

Eggplant seeds germination can be slow and uneven, justifying the use of pre-germinative treatments to improve the performance of seed lots. One option of treatment is the controlled hydration of seeds by priming. In this way, this study aimed to evaluate the performance of eggplant seeds cv. Embu submitted to different methodologies of priming. The seeds used in the experiment were stored in cold chamber (15º C and 55% RH) in paper bags. The research was carried out at Central Laboratory of Seeds/UFLA. The seeds were submitted to the priming in aerated solutions varying the following factors: temperature (15º C and 25º C), time (24, 48 and 72 hours) and solution (water, PEG, KNO3 and PEG+KNO3). Seeds were washed in running water and dried at 30º C, until the return to the initial moisture content, around 10%. The variables analyzed were percentage of germination, percentage of emergence, speed index of emergence and electrical conductivity. The treatments were arranged in a completely randomized design, according to a factorial arrangement 2x3x4+1 (control - seeds without priming). The results showed that priming improves the vigour of eggplant seeds with no effect on viability; the priming in water or KNO3 is efficient to improve the seed vigour and priming in water or KNO3 may use temperature of 15º C or 25º C for 24, 48 or 72 hours.

O transplante pulmonar consolidou-se como a melhor opção terapêutica para diversas pneumopatias terminais. O baixo número de doadores viáveis ainda persiste como uma grande limitação ao aumento do número de transplantes de pulmão, causando alta mortalidade na lista de espera. Diferentemente do transplante de outros órgãos sólidos, a maior limitação do transplante pulmonar não é o número absoluto de doadores e sim a viabilidade desses órgãos, que é reduzida devido às agressões ao pulmão ocasionadas pela morte encefálica e aos cuidados na UTI. Diversas são as propostas para o aumento do número de doadores: intensificação das campanhas de doação, o uso de doadores com coração parado, transplante pulmonar lobar intervivos e maior flexibilidade dos critérios para aceitação de doadores de pulmão. Todavia, a proposta que atrai a atenção de diversos grupos de transplante pulmonar é a perfusão pulmonar ex vivo, principalmente pela perspectiva de recuperação de pulmões inicialmente descartados. Esse sistema consiste na reperfusão e ventilação do bloco pulmonar isolado em um circuito de circulação extracorpórea modificado. Devido aos bons resultados apresentados e à perspectiva de aumento no número de órgãos aptos a transplante, diversos grupos têm estudado a técnica. Pesquisadores na Suécia, Canadá, Áustria, Inglaterra, Espanha e Brasil já possuem experiência sólida com o método e introduziram algumas variações. O objetivo deste artigo foi revisar o desenvolvimento, o estado da arte e as perspectivas futuras do modelo ex vivo de perfusão e recondicionamento pulmonar.
