Item Plasticidade fenotípica e respostas comportamentais de novilhas Girolando em pastejo contínuo no semiárido pernambucano(2023-09-11) Bezerra, Ingrid do Nascimento; Almeida, Gledson Luiz Pontes de; http://lattes.cnpq.br/2328849810614673; http://lattes.cnpq.br/4518487877353767The indicators of thermal stress for ruminants are described according to the magnitude of the meteorological elements, physiological, behavioral adjustments, and productive response. This research was conducted to evaluate the ingestive behavior and phenotypic plasticity of Girolando heifers subjected to continuous grazing in the semiarid of Pernambuco. Three heifers of 7/8 Dutch-Gir genetic composition were evaluated, submitted to a paddock with 40 x 40 m brachiaria, for 21 days. The meteorological variables recorded in the production environment were the dry, bulb temperature (°C) and the relative humidity of the air (%), which allowed the thermal characterization through the temperature and humidity index (TM). The behavior of heifers was quantified through observation by instantaneous scanning of activities, walking, drinking, eating, ruminating, lying down, leisure and standing. The physiological responses recorded were rectal temperature (°C) and respiratory rate (movement mia-1). The experimental design was completely randomized in a 2 x 3 factorial arrangement (shifts x evaluation period). Behavioral variables were subjected to te chi-square and probability test. The physiological parameters were subjected to analysis of variance and application of the Tukey test at the level of 5% significance. The THI did not exceed 89 units, which characterizes the critical limit of moderate stress for the animals. The heifers proved to be adapted to the climate of the region, as, during the study period, they showed sufficient physiological and behavioral alteration capacity to maintain homoeothermic.Item Influência do desconforto térmico no espaço intraescolar no processo de aprendizagem(2021-12-23) Caminha, Vitória Praciano Karst; Costa, Veridiana Alves de Sousa Ferreira; http://lattes.cnpq.br/8623894938993142; http://lattes.cnpq.br/9482529082487484The learning process can be affected for many reasons, both internal as external to the subject. In this work, we reflect about the thermal discomfort in the intraschool space and your influence in the learning process of students. Specifically, we find to investigate the factors which constitute the thermal discomfort, analyse the relation between the thermal discomfort and the learning process of students and reflect about solutions which can help the school management in order to minimize possible problems of learning process. It is about a qualitative research of theoretical nature, where through a work of literature review about the topic covered, we moot about how the thermal conditions of a classroom can interfere on the teacher's performance and the learning process of students. Also we covered the study of the Givoni’s Psychrometric chart for understanding obtaining methods of thermal comfort on indoor spaces and study of the thermal comfort, for what be known your influence on cognition. The reflections indicated that when a thermal ambient does not situate in a comfort zone, there are compromises in the learning process, that is why the measuring of the air temperature and humidity are important to intervene when these conditions are not at an adequate level. From that, we suggest measures that can be taken by school management in order to search methods the reduce de thermal discomfort in the intraschool space, jutting the importance of dialogued and “mediated” management in the search for an ambient conductive to learning process, including a comfortable and appropriate ambient from a thermal viewpoint.
