Indústria de base: um olhar humano sobre a formação do jogador de futebol

O presente trabalho busca trazer um olhar mais humano para a formação de jovens jogadores de futebol. A carreira é uma das mais almejadas pelas crianças em um país onde a educação primária ainda é deficitária. Soma-se isso à cultura enraizada na parte massiva da população de que estudar não é substancial. Deslumbrados pela fama e a importância dos jogadores profissionais, evidenciadas pela mídia esportiva e presentes na sociedade brasileira, estes garotos passam a buscar o mesmo para si, sem saber dos riscos e dificuldades que a carreira pode oferecer. Muitos deles esquecem-se da vida escolar e, caso não tenham sucesso na carreira profissional futebolística - o que acontece com a maioria, correm sérios riscos de ficarem marginalizados perante a sociedade. Este trabalho busca mostrar a visão de jovens que já estiveram envolvidos no universo das categorias de base do futebol e não prosseguiram no esporte, mas souberam priorizar os estudos e ter uma profissão alternativa. Mostra também depoimentos de profissionais que lidam com jovens que ainda alimentam esse sonho. Por último, traz notícias em geral do mundo do futebol de base

A biografia como registro da memória na obra do Visconde de Taunay

Le but de cet article est de démontrer que la production de textes biographiques a été une activité constante pendant toute la carrière intellectuelle et politique du vicomte de Taunay, de façon à contribuer pour rendre célèbres des personnalités brésiliennes et étrangères qui, selon lui-même, ont joué un rôle important dans le projet de constitution de la nationalité brésilienne. Em outre, ce texte vise signaler un aspect caractéristique de la méthode biographique adoptée par l’écrivain, puisqu’il va au-délà de la chronologie tradionnelle qui considère la naissance et la mort comme points de répère identifiant le début et la fin du récit: d’autres textes (écrits ou non par lui) s’y ajoutent toujours, de manière à le rendre fragmentaire et, par conséquent, plus proche de la discontinuité et du caractère aléatoire de l’existence humaine.

Economic aspects of production of Caiman crocodilus yacare

The breeding of crocodilians is still a recent activity in Brazil. Its peak was in the 1990's, but it has gaps in its production, as there are no norms for the commercial breeding of these animals in captivity. However, its economic potential is great, and the search for ecological balance and viability of commercial production has become a challenge among farmers of this activity. Therefor, the objective of the study was to economically analyze the production of Caiman crocodilus yacare on a farm located in Caceres, state of Mato Grosso, identifying relevant items of costs in the activity, as well as the parameters related to the profitability and viability of the activity. The economic results for the breeding of this animal were positive, with profitability ratios higher than 70%.

Impaired protamination and sperm DNA damage in a Nellore bull with high percentages of morphological sperm defects in comparison to normospermic bulls

The routine semen evaluation assessing sperm concentration, motility and morphology, does not identify subtle defects in sperm chromatin architecture. Bulls appear to have stable chromatin, with low levels of DNA fragmentation. However, the nature of fragmentation and its impact on fertility remain unclear and there are no detailed reports characterizing the DNA organization and damage in this species. The intensive genetic selection, the use of artificial insemination and in vitro embryo production associated to the cryopreservation process can contribute to the chromatin damage and highlights the importance of sperm DNA integrity for the success of these technologies. Frozen-thawed semen samples from three ejaculates from a Nellore bull showed high levels of morphological sperm abnormalities (55.8±5.1%), and were selected for complementary tests. Damage of acrosomal (76.9±8.9%) and plasma membranes (75.7±9.3%) as well as sperm DNA strand breaks (13.8±9.5%) and protamination deficiency (3.7±0.6%) were significantly higher compared to the values measured in the semen of five Nellore bulls with normospermia (24.3±3.3%; 24.5±6.1%; 0.6±0.5%; 0.4±0.6% for acrosome, plasma membrane, DNA breaks and protamine deficiency, respectively) (P<0.05). Motility and percentage of spermatozoa with low mitochondrial potential showed no differences between groups. This study shows how routine semen analyses (in this case morphology) may point to the length and complexity of sperm cell damage emphasizing the importance of sperm function testing.

A contribuição do PIBID no processo de formação do pedagógico

This paper seeks to understand the importance of Pibid (Institutional Scholarship Program for Teacher Initiation) in initial formation, more specifically in the pedagogue's formation. The interest for research was motivated by my inclusion in this program, through the interdisciplinary subproject called University and school thinking of interdisciplinary teacher formation: research, reflection and action in which I participated from August 2011 to December 2013. I developed a qualitative survey of bibliographic character, which aims to analyze the theoretical productions in the field of education and that has the focus the Pibid's contribution as well as its potential. For this purpose, I considered the articles located in the Annals of the XVI ENDIPE (National Meeting of Didactic and Teaching Practice) in 2012, in all its themes (Educational policies and impacts at school and in the classroom, Policies of initial formation and continuing formation of teachers and Didactics and teaching practices in contemporary school reality: findings, analysis and propositions). I believe that the research can contribute to rethink the initial formation practices by providing subsidies to the graduated on the teaching career, raising the quality of basic education

Low serum potassium levels increase the infectious-caused mortality in peritoneal dialysis patients: a propensity-matched score study

Background and ObjectivesHypokalemia has been consistently associated with high mortality rate in peritoneal dialysis. However, studies investigating if hypokalemia is acting as a surrogate marker of comorbidities or has a direct effect in the risk for mortality have not been studied. Thus, the aim of this study was to analyze the effect of hypokalemia on overall and cause-specific mortality.Design, Setting, Participants and MeasurementsThis is an analysis of BRAZPD II, a nationwide prospective cohort study. All patients on PD for longer than 90 days with measured serum potassium levels were used to verify the association of hypokalemia with overall and cause-specific mortality using a propensity match score to reduce selection bias. In addition, competing risks were also taken into account for the analysis of cause-specific mortality.ResultsThere was a U-shaped relationship between time-averaged serum potassium and all-cause mortality of PD patients. Cardiovascular disease was the main cause of death in the normokalemic group with 133 events (41.8%) followed by PD-non related infections, n=105 (33.0%). Hypokalemia was associated with a 49% increased risk for CV mortality after adjustments for covariates and the presence of competing risks (SHR 1.49; CI95% 1.01-2.21). In contrast, in the group of patients with K < 3.5mEq/L, PD-non related infections were the main cause of death with 43 events (44.3%) followed by cardiovascular disease (n=36; 37.1%). For PD-non related infections the SHR was 2.19 (CI95% 1.52-3.14) while for peritonitis was SHR 1.09 (CI95% 0.47-2.49).ConclusionsHypokalemia had a significant impact on overall, cardiovascular and infectious mortality even after adjustments for competing risks. The causative nature of this association suggested by our study raises the need for intervention studies looking at the effect of potassium supplementation on clinical outcomes of PD patients.

Evaluation of microwave-assisted pretreatment of lignocellulosic biomass immersed in alkaline glycerol for fermentable sugars production

A pretreatment with microwave irradiation was applied to enhance enzyme hydrolysis of corn straw and rice husk immersed in water, aqueous glycerol or alkaline glycerol. Native and pretreated solids underwent enzyme hydrolysis using the extract obtained from the fermentation of Myceliophthora heterothallica, comparing its efficiency with that of the commercial cellulose cocktail Celluclast (R). The highest saccharification yields, for both corn straw and rice husk, were attained when biomass was pretreated in alkaline glycerol, method that has not been previously reported in literature. Moreover, FTIR, TG and SEM analysis revealed a more significant modification in the structure of corn straw subjected to this pretreatment.Highest global yields were attained with the crude enzyme extract, which might be the result of its content in a great variety of hydrolytic enzymes, as revealed zymogram analysis. Moreover, its hydrolysis efficiency can be improved by its supplementation with commercial beta-glucosidase.

Aquecimento vocal para o canto erudito: teoria e prática

Vocal warm-ups are essential for the technical training of the singer, for good speech and performance, as well as essential for good vocal health and a long-lasting career. Objective: To analyze the theory and practice of the vocal warm-up in classical singing, from the perspective of different professionals in the voice field including: teachers, speech therapists and singers. Method: descriptive search, quantitative in nature, cross-sectional, with a questionnaire for voice teachers, singers and audiologists. The sample consisted of 165 subjects: 86 voice teachers, 64 speech pathologists, and 15 singers. Results: Teachers of Singing (97.7 %), singers (95.3 %) and students (93.3 %) use the vocal warm-up. Conclusion: From the results we can infer that most of the professionals surveyed point to the importance of the implementation of the vocal warm-up before a performance, and the strategy used by most voice instructors, speech therapists and singers is vocalization, i.e. aesthetic warm-up.
