Abstract: despite the consolidation of stricto sensu postgraduate programs in physical education (pp-pe), critics have been noted. among the principal, it is pointed out the technical formation and specialization on the initial periods of scientific formation, the distance between knowledge and society, the emphasis on the quantitative bibliographic production, guiding the aim of research for publication. this form of scientific production is entitled as academic fordism. thus, the aim of this essay is discuss the orientation politic of the pp-pe and your implication to knowledge production and academic formation. the emphasis on bibliographic production and the devaluation of the pe likes area of intervention may implicate on the critical formation and result in mischaracterization of area.
Spatial variation in the stable isotopes of 13C and 15N and trophic position of Leporinus friderici (Characiformes, Anostomidae) in Corumbá Reservoir, Brazil

Abstract: stable isotopes of carbon (d13c) and nitrogen (d15n) were used to describe sources of energy and trophic position for adult leporinus friderici in the area of the corumbá reservoir, brazil. samples were collected from april 1999 to march 2000. spatial variations were not identified in the isotopic composition. the maximum and minimum contribution of c4 plants calculated integrating the variation of plants and fish were 47.7% and 2.4%, respectively. among c3 plants, periphyton presented closer isotopic values to those observed for fishes, corresponding to an important carbon source. the proportion of ingested plant item is larger in rivers upstream from the reservoir (42.7%), which justifies the smaller trophic level among there. however, in the reservoir, the ingestion of fish was 81.4%, while ingested plants contributed with 18.6%. downstream from the dam, participation of plant item was even smaller (14.4%). although the trophic position calculated with diet data was proportional to the one calculated with d15n values, the former elevated the trophic level of l. friderici in the food web, because estimated trophic positions were based on fish items belonging to the 2nd (a) and to the 3rd (b) trophic levels.

Viscovini, Ronaldo Celso;Lopes, Nilson Benedito;Pereira, Daniel;
Revista Brasileira de Ensino de Física , 2011, DOI: 10.1590/S1806-11172011000100019
Abstract: in this work we developed a software that calculates the external doses in a plant radioactive, and presented graphically in contour dose (isodoses) using the geometric method. it was created to help the lessons of radioprotection, but can be used to review plans for radioprotection. the software was written for version 6.0 of the application mathematica？ from wolfram research for the algebraic and numerical calculation, but can be easily translated into maple？, matlab？ or delphi？. to demonstrate its application, this software is used to prepare the plan for radioprotection of a laboratory that uses a gas isotopic laser (14co2).
Creatina: auxílio ergogênico com potencial antioxidante?
Souza Junior, Tácito Pessoa de;Pereira, Benedito;
Revista de Nutri？？o , 2008, DOI: 10.1590/S1415-52732008000300010
Abstract: creatine is largely used as an ergogenic aid with some evidence regarding its positive effect on lean body mass, strength/power and muscle endurance. however, most studies were not capable of identifying biochemical mechanisms that could explain its effect on fatigue or muscle protein turnover. there is also the possibility that some individuals are non-responsive to this supplement. another possible effect of creatine that has been recently investigated is its antioxidant action, but few studies explored this subject. nonetheless, it can be emphasized that the antioxidant effect of creatine works in the organism in the following way: 1) indirect action as an energy buffer, due to the increase in muscle phosphocreatine concentrations which would favor a reduced production of metabolites of the purine nucleotide cycle (cycle of lowenstein) and, as a consequence, a drop in the production of hypoxanthine, xanthine, uric acid, and reactive oxygen species; 2) direct action (a less powerful action when compared with known antioxidants, such as reduced glutathione). yet, it could still work in association with them. the objective of this work is to review the available data on the two abovementioned mechanisms.
Physiological concepts in physical education and sports training: stress, homeostasis and allostasis
Tácito Pessoa de Souza Junior,Benedito Pereira
Revista Brasileira de Cineantropometria e Desempenho Humano , 2008,
Abstract: The objective of this review article is to discuss the concepts of stress and homeostasis (homeos = equal; stasis = stable) and to expose their limitations on the basis of recent evidence demonstrating that the supposed internal stability of living organisms is merely apparent, and is even independent of environmental factors. This internal instability is often observed by researchers investigating circadian rhythms (hormone secretion), temporal series (heart rate) and behavior (hunger and satiety), who argue in favor of substituting the theory of homeostasis by the concept of allostasis (allo = different; stasis = stable). Indeed, these researchers suggest that the objective of regulation and control is not stability. There are two consequences for Physical Education and Sport if allostasis is accepted as a physiological paradigm: 1. Selye’s concept of stress requires a new defi nition and interpretation, with a clear impact on the concept of load and overload; 2. Noakes’ central governor hypothesis to explain the fatigue resulting from intense physical exercise loses its relevance, as will be discussed in this paper. Furthermore, it is very diffi cult for the model of stability by staying the same to explain why performance is improved by physical training or why we have a predisposition for this type of recognizedly anti-homeostatic activity. We intend to demonstrate the possibility that the allostatic concept of stability through change can explain these contradictions. Resumo O objetivo desta revis o é discutir criticamente os conceitos de estresse e homeostase (homeos = igual; stasis = constancia) e expor suas limita es em fun o de recentes evidências que demonstram que a suposta estabilidade interna dos organismos vivos é apenas aparente, inclusive sendo independente de fatores ambientais. Essa instabilidade interna é freqüentemente constatada por pesquisadores dos ritmos circadianos (secre es hormonais), séries temporais (freqüência cardíaca) e comportamento (fome e saciedade), que argumentam a favor da substitui o da teoria da homeostase pela no o de alostase (allo = diferente; stasis = constancia). Na verdade, o propósito da regula o e controle segundo os mesmos n o é a constancia. Duas conseqüências para a Educa o Física e Esporte com a aceita o da alostase como paradigma fisiológico s o: 1.

Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.62015
Abstract: The measure of management risk has been a constant in Economy in the recent past. This issue is present on any kind of economic or financial activity. The solution adopted for international authorities, increasing liquidity of financial market and generating new indicators to support making decisions, means the continuity of applying the monetary theory as general criteria to solve the actual crisis. In this labyrinth, the manuscript uses the Accounting Methodology of Edgeworth’s Box as a new methodology to measure the management of Banking Companies and analyzes the acquisition of the CAM and Bank Sabadell, two Spanish banking companies. Finally, the manuscript analyzes the financial crisis in Spain through the behavior of listed banking companies in IBEX 35. The manuscript concludes that accounting can explain equilibrium in economy, and it only needs to know how they can be measured properly.

Abstract: lipids-rich wastewater was partial hydrolyzed with porcine pancreas lipase and the efficiency of the enzymatic pretreatment was verified by the comparative biodegradability tests (crude and treated wastewater). alternatively, simultaneous run was carried out in which hydrolysis and digestion was performed in the same reactor. wastewater from dairy industries and low cost lipase preparation at two concentrations (0.05 and 0.5% w.v-1) were used. all the samples pretreated with enzyme showed a positive effect on organic matter removal (chemical oxygen demand-cod) and formation of methane. the best results were obtained when hydrolysis and biodegradation were performed simultaneously, attaining high cod and color removal independent of the lipase concentration. the enzymatic treatment considerably improved the anaerobic operational conditions and the effluent quality (lower content of suspended solids and less turbidity). thus, the use of enzymes such as lipase seemed to be a very promising alternative for treating the wastewaters having high fat and grease contents, such as those from the dairy industry.

Pereira, Benedito Alísio da Silva;Venturoli, Fábio;Carvalho, Fabrício Alvim;
Pesquisa Agropecuária Tropical , 2011, DOI: 10.5216/pat.v41i3.12666
Abstract: seasonal forests cover about 15% of the brazilian savannah and are among the most degraded and fragmented vegetation types in this biome. this study aimed to provide an overview of the current knowledge on these forests and disseminate information that can contribute to the amplification and deepening of previous studies. it shows that previous studies have already explained a large amount of questions raised by earlier researchers, but that the knowledge on some important aspects still remains incomplete. the anthropogenic activities reduction in the remaining areas, as well as the restoration of connectivity between fragments and the development of sustainable exploitation methods, were pointed out as major challenges to be faced by people involved in the study and management of these forests.
