A interdependência da prática docente e a construção da héxis corporal de professores de Educação Física e suas consequências na unidade escolar

This article aims to show the interdependence between teaching practice and the construction of body hexis of Physical Education teachers and its consequences at schools. It can be observed by the social workers that teach it in a elementary school in the city of Araraquara- -SP. It was established, as basic assumption of this issue, that the social construction of body hexis of Physical Education teachers is a process in constant evolution, because it is the result of the life story with interventions from the social context in which the learner lives. The hexis is the dimension that allows the internalization of the consequences of social practices, and also its body exteriorization, through the way of speaking, gesturing, looking, walking, head posture, faces, ways of sitting, to handle instruments, more and more associated with the voice sound of social workers. Children are particularly attentive, in all societies, to these gestures and postures in which they express themselves in their eyes, anything that features an adult. Finally, it understands the importance of the body hexis in the learning process specifically in school physical education. This practice will incite important behavioral changes in their residence within the school and possibly in a higher education.

Influência da temperatura e do termoperíodo sobre a taxa metabólica de repouso em cascavéis, Crotalus durissus (Serpentes: Viperidae)

Snakes are ectothermic animals and, therefore, their physiological functions are strongly affected by temperature. For instance, the resting metabolic rate (RMR) of this animals increase with the rise in body temperature. However, metabolic determinations in ectothermic organisms, including snakes, are generally made by submitting the animals to constant temperature regimes. This experimental procedure, although widely used, accepted and certainly suitable in several cases, submit the animals to a very different situation from that experienced by them in nature. In fact, ectothermics are known by presenting extensive variations in their body temperatures trough the day and/or seasons. If this disagreement between the thermal biology of the animals and the experimental conditions, for instance over the circadian cycle, affects the determinations of metabolic rates of ectotherm animals, remains quite uncertain. Thus, this study aimed to test the effects of different thermal regimes (fluctuating vs constant) in different temperature ranges over the TMR of rattlesnakes (Crotalus durissus). Therefore, the TMR of rattlesnakes was measured by the oxygen consumption rates ( V O2) in the constant temperatures of 15°C, 20°C, 25°C, 30°C and 35°C. For fluctuating regimes, snakes were measured in thermoperiods of 12/12 hours, as follows: 15°C and 25°C; 20°C and 30°C; 25°C and 35°C. Our results show that the RMR of C. durissus rises as the temperature increases, regardless of the thermal regime. The obtained RMR in the constant regimes of 20°C and 25°C was not different from that measured in the correspondent fluctuating regimes (i.e., 15 - 25°C e 20 - 30°C). However, at constant 30°C, the RMR was significantly higher than that obtained in the 30°C fluctuating regime (25 - 35ºC). This indicates that the potential effects in submitting of snakes to different thermal regimes of its thermal biology become more important with...

Body temperature, Aldrete-Kroulik index, and patient discharge from the Post-Anesthetic Recovery Unit

Patient discharge from post-anesthetic recovery (PAR) depends, among other factors, on normothermia and the patient's score on the Aldrete-Kroulik index. The objective of this study was to verify the relationship between the Aldrete-Kroulik index and body temperature in patients. This study was performed at the University of Sao Paulo University Hospital. Convenience sampling was used, and the sample consisted of 60 patients of ages between 18 and 60 years who underwent general anesthesia. The patients' body temperature was obtained by tympanic measurement, and the Aldrete-Kroulik index was measured on admission and at discharge from post-anesthetic recovery. The data were processed using SPSS, considering a significance level of 5%, and the Spearman and Wilcoxon tests were applied. In conclusion, no significant correlation was found between the two parameters for discharge.

Estresse oxidativo no plasma sanguíneo de indivíduos submetidos ao esforço físico agudo seguido de crioimersão corporal

O objetivo deste estudo foi analisar a influência da crioimersão corporal (CIC) imediata ao esforço físico agudo no estresse oxidativo (EOx) no plasma sanguíneo. Participaram do presente estudo 12 homens, com idade média de 22±1 anos, submetidos ao teste de esforço físico intenso em esteira, seguido de CIC em um tanque com água a 10ºC durante 10 minutos contínuos. Do repouso ao final da CIC, os indivíduos foram monitorados através de alguns parâmetros como: o índice de percepção subjetiva do esforço (IPE) expresso conforme escala de Borg, frequência cardíaca (FC), pressão arterial (PA) e temperatura corporal (TC) através da temperatura timpânica. A análise morfológica do EOx plasmático foi realizada de acordo com o método denominado Morfologia Óptica do Estresse Oxidativo no Plasma (MEOP), utilizando-se gotas de sangue capilar. Observou-se uma significativa elevação (p<0,01) no grau do estresse oxidativo plasmático após a realização do esforço físico, em relação ao respectivo grau em repouso. Porém, esta elevação no grau do EOx foi significativamente reduzida (p<0,001) em função da CIC. Embora sejam necessários mais estudos científicos com o MEOP, concluiu-se que, para o presente estudo, este teste mostrou-se viável. Os dados encontrados no presente estudo sugerem que a CIC em água a 10ºC por 10 minutos imediatos ao esforço físico agudo com intensidade alta, apresenta-se como uma importante conduta fisioterapêutica para a normalização do EOx pós-esforço.

Los manglares de la costa brasileña: revision preliminar de la literatura

Los manglares ocurren intermitentemente a lo largo del litoral brasileño desde Cabo Orange (4°21'N) en Amapá hasta la ciudad de Laguna (28°30'S). En este trabajo se sugiere la división del litoral en 7 trechos que comparten características geomorfológicas y rangos de condiciones meteorológicas similares. Estes trechos son: Litoral Guianense, Golfão Amazónico, Litoral de Ponta Coruçá a Ponta Mangues Secos, Litoral de Ponta Mangues Secos al Cabo Calcanhar, Litoral del Cabo Calcanhar al Recôncavo Baiano, Litoral Oriental y Costa Cristalina. El mayor desarrollo del manglar ocurre en los trechos Guianense y del Gofão Amazónico. Los manglares se desarrollhan por todo el litoral aún en los sectores donde la precipitación es en el orden de 500 mm/año. En las costas expuestas se desarrolla en las áreas anegadas detrás de medanos, canales, lagunas y márgenes de los estuarios, penetrando en ocasiones 30-40 km. Coloniza además las márgenes de las grandes bahías hasta los 28°30'S donde la temperatura anual es de 19.6°C y la temperatura media del mes más frío es de 15.7°C. En el trecho del Litoral Cristalino, el manglar alcanza su límite latitudinal en el estado de Santa Catarina. Rhizophora alcanza 27°53'S mientras que Avicennia continúa hasta los 28°30'S en Laguna. En la isla de Santa Catarina se encuentran manglares bien desarrollados dominados por Avicennia. Estos manglares alcanzan un porte promedio de 7.0 ± 0.4 m, tienen un DAP de 17.9 cm, densidades totales (≥ 2.5 cm) de 431 ± 93 árboles/ha y áreas basimétricas (≥ 2.5 cm) de 7.42 ± 0.80 m2/ha. Las áreas basimétricas bajas se deben al dominio de los rodales por pocos ejemplares de diámetros moderados. Debido a estas bajas densidades, la copa es rala y los bosques son extremadamente abiertos

Descripción temporal de la estructura de mesoescala alrededor de las islas Shetland del Sur (Antártica)

[ES]El objetivo del presente trabajo es analizar la variabilidad espacial de la temperatura superficial del mar (SST) para el área comprendida entre el Paso Drake y el Estrecho de Bransfield (Antártica). Se realizaron distribuciones de SST en toda la región y en diferentes escalas temporales, conservándose importantes variaciones espaciales de la distribución de SST, demostrando que existe una importante variabilidad de la SST entre verano e invierno, alcanzando diferencias superiores a 3ºC, donde las estructuras de mesoescala superficialmente sólo se registran entre los meses de diciembre y abril, periodo correspondiente al verano Austral.
