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...

O uso de plantas medicinais por mulheres grávidas e em período de lactação é uma prática comum em diversos países. Entretanto, muitas plantas medicinais são contra-indicadas durante a gravidez e amamentação devido a vários efeitos adversos que podem apresentar, como embriotoxicidade, teratogenicidade e efeitos abortivos. Esse fato acaba expondo essas mulheres, seus fetos e bebês, a riscos de saúde desconhecidos. Assim, a proposta desse trabalho foi analisar a percepção a respeito do uso de plantas medicinais por mulheres grávidas e lactantes na ONG Bebê a Bordo, em Araraquara, São Paulo, entre 2013 e 2014. O grupo foi constituído por 96 mulheres ao todo, entre o primeiro e o último trimestre de gestação. Os dados foram coletados em encontros com grupos de gestantes utilizando questionários como roteiro e também através de entrevista oral. Esse estudo promove uma análise de natureza qualitativa. Os resultados foram baseados nos relatos de mulheres grávidas sobre o uso de plantas medicinais, a indicação de uso e conhecimento dos riscos avindos do uso. Todas as participantes foram informadas oralmente e por escrito sobre o estudo e assinaram um termo de consentimento. O uso de plantas medicinais é uma realidade entre as mulheres gestantes e lactantes da ONG Bebê a Bordo. Elas reportaram acreditar que produtos naturais não oferecem perigo à saúde. As principais fontes de informação sobre o uso de plantas medicinais durante a gravidez são familiares, vizinhos, amigos e internet. As plantas mais citadas são: hortelã, camomila, boldo, capim-cidreira e erva-doce. Tais plantas eram indicadas para náusea, indigestão, gases, constipação, ansiedade, e também para produzir leite. As mulheres gestantes e lactantes demonstraram que falta conhecimento sobre os riscos à saúde que as plantas medicinais e os medicamentos fitoterápicos podem oferecer nessas fases. Elas também comentaram sobre as dificuldades em...

Currently we live in an increasingly visual world, where images are used as non-verbal language for different interests. Considering the ease of getting a photograph and the many ways that it can find, understand that this language can be a means of reading the geographic space, appearing as text and not only as illustration for teaching geography. Thus, this work aims to try an approach between artistic photographic language and geographic scientific language, observing how different groups with different ages read the geographic space through photographs. Focusing on the school environment, we have in mind the need to work with the various pictorial means that are increasingly present in textbooks of geography teaching. Here then, as proposed, a trial in which students from elementary and secondary education will shoot what for them is the city. The analysis will be performed observing possible differences and / or common aspects in the photographs according to the age group of students groups, trying to discover how the geographic space is being read by students through images and how this trial can contribute to the basic education of discipline geography

The modernization of the world made the speed, accuracy and reliability of all existing processes become increasingly necessary. For this evolution to occur every day, the evolution of the equipment was strategic, but not as much as needed. It is necessary for such equipment to ensure its function and, in case of failure, an early diagnosis to prevent loss. Therefore the evolution of maintainability and reliability in equipment is also paramount. Thus, the growth of forms of maintenance was driven by this scenario, forming maintenance philosophies. Among many, there is the RCM, which have its focus on the identification, parameters development and performance preview. One of those methodologies from this idea is the FMEA, process that has been studied and implemented this work, aiming the anticipation of failure modes and guidance for the use of a heat exchanger and a pump. This implementation has the aid of another process of RCM, the PHA, which was also shown and implemented, these results being used to start the FMEA process. The results show the activities with the highest chance of failure, presenting also the measures to be taken to avoid or minimize them. It is shown, in this paper, concern with the valves because they maintain control and system security, and its flaws related to accidents with possible danger to people and the whole system, emphasizing the priority of action
