Ocorrência de lesões de ligamentares e músculo tendíneas ao longo das fases do ciclo menstrual de atletas de alto redimento: um estudo de caso longitudinal

Female athletes are more susceptible to injury when compared with males. This increased risk of injury, may be caused by fertile-menstrual cycle. The aims of this study were to investigate the prevalence in the occurrence of muscle-tendon and ligament injuries in different phases of the menstrual cycle over a period of high performance sports training and identify possible differences of occurrences between the phases. Fifteen female athletes, members of a women's basketball team, with ages between 15 and 22 years (average 17.5 ± 2.6 years), with regular menstrual cycles and daily practitioners of training, received follow-up during the menstrual cycle for 5 months. During the period were noted occurrences of injury in relation to the menstrual period of each athlete. The results showed 13 injuries, all of anterior cruciate ligament. The distribution of percentage values indicated a significantly higher risk of athletes suffer injuries in the follicular phase. The result makes us believe that significant elevations in the concentrations of estrogen in this fertile menstrual cycle phase, more open women to a higher risk of performing different injuries.

Educação: transformação ou reprodução

Among the various school functions in capitalist society there in the literature and common sense that the school would have a central role in correcting social inequalities produced by the capitalist mode of production. We see, in today's society, children and young people who moved by the desire to get out of where they are, usually on the outskirts, in a vulnerable situation, seek growth through the study; They see it as a way out to another reality with more opportunit ies and chances for improvement, both as regards their quality of life, and even want to change, change and influence their own reality or part of it, with the knowledge learned in school. On the other hand, there are theorists who maintain that the school reproduces the basic features of the social structure and the current system of power in society. Our goal is to discuss the transformative potential of education as opposed to its role of reproduction of social inequalities, through the essential role of the teacher, who has a high profile role when it comes to change. The teacher is one of the first professionals that we remember when we turn to the school and refer to the systematic teaching. But sometimes forms of education present in the school, afflicting much of children and young people and are characterized in order to favor certain classes and eventually stop the growth and development of those who do not meet the required standards. In this paper we intend to compare two lines of thought, alluding to pedagogical activities in class, the Paulo Freire, which brings the teacher's figure with a responsible actor for lead students to reflection of their practice; and Pierre Bourdieu, which considers the pedagogical practice as an act of imposition of values of the ruling class. The work will address the issue from literature

Used as catalysts even in organic and inorganic molecules, as additives on catalysts, electrochromic films on smart windows the tungsten trioxide have been largely studied on the lasts decades, but there is just a few about it's luminescence. Using as precursors nitric acid and sodium tungstate the tungsten trioxide were been prepared thru wet process then treating on thermic and hydrothermal treatments. Where been evaluated the effects of methodology, nitric acid concentration, duration and temperature of treatments. The samples were characterized by X-ray diffraction (XRD), Raman scattering spectroscopy (RSS), Fourier transformed infrared spectroscopy, photoluminescence spectroscopy (PLS) and X-ray excited optical luminescence (XEOL). Hydrated phases of tungsten trioxide were obtained through hydrothermal treatments and the non-hydrated phases occur with thermic treatments. The acid concentration has the ability to determine the major phase formed as well the temperature determine the hydratation of the product. With lower temperatures dihydrate phase were preferable formed and with the rise of temperature, the water molecules were lost up to the fractionary hydratation and then the non-hydrated phase with higher temperatures depending on the atmosphere used on the thermal treatment. Doping the system with europium ions even substituting tungsten or in the interstices of the matrix were not been successful, as well the XEOL spectroscopy intensity were null and quite low for ultraviolet and visible excitation photoluminescence because of oxygen defect levels localized into the prohibited band.
