The objective of this work was the analysis of the energetic ethanol production systems using as source of carbohydrates, manioc, sugar cane and maize crops. The searches were carried from the field in the Paranapanema River Valley, state of Sao Paulo in the operations of cultivation and industrial processing of raw materials for analysis. The expenditure of energy concerning the agricultural part was made by the energy consumption of stage production of one hectare of sugar cane, cassava and corn, tillage and planting procedure, inputs, driving the crop, harvest, transport industry and energy draining. The expenditure of energy referring to the part was made by the industry energy consumption of stage processing of one tonne of sugar cane, cassava and corn, in the operations of disintegration / milling, hydrolysis / treatment of the broth, fermentation, distillation and maintenance of equipment. Under the system of agronomic production of raw materials, manioc presented an energy expenditure below that of sugar cane and maize (9,528.33 MJ ha-1; 14,370.90 MJ ha-1 and 15,633.83 MJ ha-1, respectively). For the ethanol produced, the operations of cultivation has consumed 1.54 MJ l-1 with manioc; MJ 1.99 l-1 with sugar cane, and 7.9 MJ l-1 with the corn. In the industrial processing of a ton of raw material, sugar cane presented an energy cost less than the cassava and maize (1,641.56 MJ t-1; 2,208.28 MJ t-1 and MJ 3,882.39 t-1, Respectively), however, showed a higher cost than when they related to ethanol produced (19.38 MJ l-1; 11.76 MJ l-1 and 11.76 MJ l-1, respectively). In the final energy balance for each megajoules of energy invested in sugar cane were required 1.09 MJ (9%), for each megajoules of energy invested in manioc were required 1.76 MJ (76%) and for each megajoules energy invested in maize were required 1.19 MJ (19%). Overall, it appears that the manioc consumes less energy than sugar cane and corn crops in the process of agribusiness obtaining ethanol.

Objective and closed questions were applied to 15 - 21 years old individuals under regular resistance exercise practice and self-reported nutritional supplements users, approaching training practices, type of substance feed and socioeconomic characteristics. The data were treated by frequency around the mean value. Major difference was observed to the goal of improvement in physical fitness (Guaruja 21% and Bauru 9.6%), close to the muscle hypertrophic enhancements (Guaruja 22% and Bauru 19.2%), and health proposes (17.3%), which was only reported in the country city. The monthly employment with supplements was observed to be close to one hundred Real, in both regions (Guaruja 79% and Bauru 80%). Even, based on different purposes, the supplements feed practice was closed to the goals, showing a reliable referential of use, but done without appropriated professional care.

This research leads to a meta-analysis of scientific production in energy efficiency in industrial sectors, recorded in ten (10) leading journals in Administration and Engineering Production in Brazil, between 2001 and 2011. To this end, this scholarship was examined based on the following parameters: a) the total contribution and journal articles, b) methods used in studies, and c) the theoretical gaps to exploit. The diagnosis is that one infers: academic work in energy efficiency industries accounted for only twenty-nine (29) published articles, and only eight (8) have energy efficiency as a central theme of the work. Although the results still showed a rising trend in the number of publications since the last five (5) years analyzed showed 65.5% of all published files relating to energy efficiency. It contributes, therefore, the systematization of the academic production in the area of energy efficiency and business subsidies are provided for this field of research in Brazil.
