Estudou-se a melhor relação entre lisina digestível (LIS) e energia metabolizável (EM) e efeitos no desempenho e balanço de nitrogênio em leitões na fase de creche. No desempenho foram usados 216 leitões dos 6,90 ± 1,11 kg de peso inicial aos 12 kg, aproximadamente. No metabolismo eram 48 leitões com 9,31 ± 2,09 kg. As concentrações de LIS eram: 1,302; 1,390 e 1,497% e de EM: 3.510, 3.700 e 3.830 kcal/kg, combinadas em um arranjo fatorial 3 × 4 e distribuídas em delineamento de blocos ao acaso. No desempenho dos leitões houve interação LIS em no ganho de peso e conversão alimentar. No ganho de peso a resposta para LIS foi linear crescente nas dietas com 3.510 kcal e 3.830 kcal de EM. Na conversão alimentar observou-se efeito quadrático de LIS nas dietas que continham 3.510 kcal e efeito linear de LIS nas dietas com 3.830 kcal de EM. O efeito quadrático de LIS dentro de 3.510 kcal indicou 1,44% do aminoácido digestível como nível ótimo ou a ingestão de 4,16 g LIS/Mcal de em consumida. A resposta linear positiva na conversão alimentar ao acréscimo de LIS nas dietas com 3.830 kcal em indica maior eficiência dos leitões ao acréscimo do aminoácido quando o nível de energia é alto. No ensaio de metabolismo o aumento de em sugere maior retenção de N, enquanto o acréscimo de LIS sugere menor retenção do N ou na relação Mcal de EM:% LIS. A interação observada nos dois ensaios, todavia, indica que a relação LIS:EM, depende do nível energético e da característica considerada. A variação de LIS e em na dieta indica 4 g LIS/Mcal de em consumida, o que corresponde à ingestão diária aproximada de 7,8 g de LIS.

The alimentation of fitness people is fundamental by health. This study it has for objective to evaluate of quali-quantitative form the proteic-caloric ingestion, the nitrogen balance and its relation caloric ingestion/estimated metabolic rate, in colleges student practicing of body-building. Eleven body-builders student (18 until 30 years old), both sex, had been analyzed. The attainment of data used an alimentary register, and the gotten information were analyzed together with the nitrogen balance from 24 hours of piss collection. We observed that the nitrogen balance of individuals that make use of some protein supplement is significantly bigger than individuals that do not consume no type of it. This because, the percentile caloric obtained from protein ingestion is significantly raised, and this associate to the caloric ingestion in this group also is raised, determines the obtained results.

This paper focuses on the process of institutionalization of public policies of Solidarity Economy in the federal government during President Lula’s first term (2003-2006). During this period, the authors analyze in particular the creation and operation of the National Secretariat for Solidarity Economy (SENAES) – a structure established under the Ministry of Labor in order to implement social inclusion policies designed to generate jobs and income. This approach allows the formulation of hypotheses about the institutional context of SENAES, its scope, limits and challenges.

Based on climatological data and energy flow, this paper analyzes the behavior observed in microclimatic an important remnant of cerrado in the São Paulo State. The seasonal climate is well marked, in the study area, with two climatic periods (one dry and one wet). The vegetation presents physiology as a function of water availability and the local thermal conditions and can be seen marked changes in the landscape due to the more or less presence of solar radiation. It’s important to understand the ecosystems behave in the context of global change. It has gained the attention of many researchers in the world.

The objective of this work was to calculate the energetic values in passion fruit commercial beverages (whole juices, reconstituted juices, tropical juices, and nectars) by their centesimal composition. Then, the energetic values were compared to the caloric values as described on the nutritional facts from the beverageslabels. Analyses of moisture, protein, lipids, ashes, and carbohydrates were done in 25 commercialbeverages samples. In order to calculate the energetic value of each sample, the following conversion factors were used: 4 kcal.g-1 for carbohydrates, 4 kcal.g-1 for proteins and 9 kcal.g-1 for lipids. To allow the comparison of the results, the energetic values printed on the labels were converted into kcal.100g-1 usingthe beverages density. Overall, the commercial beverages calculated energetic values were similar to the nutritional facts.

The knowledge of the workers energy content is essential to measure the energy availability for maintenance and performance of activities essences for the colony growth. But little is known about the workers energy content, and how much will be available to carry out activities, for example, the excavation of the nest. The present study determined the lipid content and energy content of the worker ants inactive before and after excavation activity. Through the lipids determination, it can be calculated the energy content of workers resting (standing) with those which excavated. The lipid content and energy content of the workers were on average 9.1±0.8% and energy content of the workers was on average 111.31±54.71J, respectively, however, the experimental series did not differ significantly. Additionally, catabolic flux rate based in workers body mass was 14.76±10.11µW. It was concluded that the energy resource for the excavation of the nest is not coming from reserve lipid body, and thus the energy content of the workers did not change before and after excavation activity.
