Jogo de handebol e futsal na escola: possibilidades e limites pedagógicos

Sports team, specifically soccer and handball, has traditionally composing the physical education school contents as a curriculum component. There are several criticisms to extend this approach beyond the sportive discourse. While we recognize this need for expansion, we believe that the methodological endeavors to teach these sports content are still very poor, requiring, therefore, studies that guide us in changing not only contents but also the way of teaching it, which implies new e teaching, pupils and teaching relationship perspective. In this sense, the objective of this study was to identify and analyze, from a sports team tactics teaching approaches of invasion, the demonstrations by students, the phases of handball and soccer games, as well as the elements/dynamic structural, functional and operational in the same school environment. Given this objective, qualitative research, specifically, collaborative action research, best meets investigation is this scenario, since classroom teacher and students also participated in the content construction and strategies undertaken during the intervention. The study enrolled 28 students in the fifth grade, aging 10 to 11 years, in a Bauru/SP public school, physical education teacher and the researcher. Were planned and taught together, 14 classes over a semester with the handball and futsal content, guided for teaching tactics approaches. The data collections were made through systematic lessons observation (through filming and recording diary), interviews with students and descriptive reports made by the classroom teacher and researcher. The results indicate that there was an improvement in the phases of soccer and handball game, even though only the latter has changed its category phase to decentralized anarchic phase. Several students showed in the situational interviews, a more elaborate game understanding than the one identified in the game demonstration. In the analysis of relationship levels..

Características morfogênicas e estruturais da Brachiaria brizantha cv. Marandu submetida a diferentes doses de nitrogênio e alturas de resíduos

The objective of this study was to evaluate the rate of leaf appearance, leaf elongation rate, number of green leaves, length of blade and stem of Brachiaria brizantha cv. Marandu under different nitrogen levels and two residue heights. A randomized block design was used in a 4 x 2 factorial scheme, four doses of nitrogen (100, 200, 300 and 400 kg N ha(-1) year(-1)) and two residue heights (5 and 15 cm). There was significant interaction between residue height and nitrogen levels for leaf appearance rate of signal grass, which was influenced negatively and linearly by the residue heights being observed an average reduction of 28.20% from lower to higher residue. There was no interaction between the levels of nitrogen x residue height on the number of green leaves. The dosage that provided the highest stalk in the residue height of 5 cm was of 271.5 kg N ha(-1). An increase of 0.0745 cm tiller(-1) day(-1) for 1 kg of N ha(-1) applied to height of 15 cm of residue was observed. Nitrogen fertilization contributes positively to growth and development of rates of appearance and leaf extension. The management of pasture of Brachiaria brizantha cv. Marandu with 5 cm of residue and fertilization with 100 kg N ha(-1) provided better answer morphogenic traits.

Obtenção e caracterização óptica e elétrica de 'La''Ta'O IND.4' e LiTaO Ind.3 puros e dopados com Eu POT.3+

Eletronicalceramics are used in many applications such as: multilayer capacitor, transducer, pyroelectric sensors and electrooptic devices. In recent years there has been a growing demand for eletronicalceramics with better performance and functionality. This demand has accelerated the development of synthesis techniques to produce powders with well-defined particle size, shape and crystallinity. The eletronicalceramics in the form of bulk are determined by their performance characteristics of the powders used and the preparation process. So, physical and chemical properties of powders, such as chemical control of stoichiometry, purity, homogeneity, particle size and shape should be observed when choosing the methods of synthesis. Among the techniques used so far, the polymeric precursor method, also known as Pechini, has been considered ideal for the preparation of nanosized powders. Thus, this research project aims to use the polymeric precursor method to prepare powders of lithium tantalate and lanthanum tantalate, with good chemical stability. In this aspect is proposed to investigate the effects of variation of the concentration of europium about the properties of tantalate because doping with Eu3 + indicates that they may occupy different sites in the crystal structure, as in the case of LiTaO3. Effects of things like occupation sites, stability of phases and formation temperature have been previously investigated by the group, which motivated the formulation of this project. Our proposal aims to introduce the Eu3 + LaTaO4 and LiTaO3 and study the structural and optical properties of the powders obtained by Pechini method, as well as correlate these studies with the electrical properties of the material, mainly the Ironelectricty Hysteresis.

As fases do treinamento de natação influenciam os substratos energéticos, cortisol e leucócitos

The effect of physical exercise in immune function has been extensively studied. The intensity and duration of physical exercise have considerable influence in immunologic parameters. However, few studies have compared different exercise intensities in different stages of a physical training program. Thus, the aim of this study was to verify the metabolic, hormonal and immunologic changes before and after acute intermittent swimming exercise, following different stages of training program. Seventeen male swimmers were evaluated in three stages of training. The intensity of the three sessions was 90% (anaerobic potency – PAN), 70% (aerobic potency - PAE) and 98% (lactate tolerance – TLA) of the maximal speed from the best time of the distance, resulted from peak performance in competition. Blood samples were collected pre and immediately after exercise for cells counting and measurement of substrates and cortisol concentrations. It was used ANOVA to verify the significance of difference (p<0.05). There was a significant increase of glucose and cortisol post exercise in the PAN and PAE sessions. Glutamine increased significantly in PAE and TLA. Leukocytes increased significantly after the three different sessions and lymphocytes decreased significantly on PAE and TLA. In conclusion, it was demonstrated that changes of the several parameters studied in different stages of training program can cause temporary alterations in immune cells and may compromise resistance to common minor illnesses and athlete performance.
