Regulação da temperatura corporal : sensores e efetores térmicos
(Universidade Federal de São Carlos, 2016-02-12) Scarpellini, Carolina da Silveira; Almeida, Maria Camila; https://lattes.cnpq.br/9447755981910182; Bícego, Kênia Cardoso; https://lattes.cnpq.br/0169967378071426; https://lattes.cnpq.br/9063522962257626
In this study, we aimed at investigating the involvement of the warmth-sensitive channel – TRPV4 (in vitro sensitive to temperatures in the range of approx. 24–34°C) – on the thermoregulatory mechanisms in rats. We treated rats with a chemical selective antagonist (HC-067047) of the TRPV4 channel and measured core body temperature, metabolism, heat loss index and preferred ambient temperature. The behavioral mechanism was also assessed after treatment with topical agonist (RN-1747). Our data revealed that intravenous blockade of this channel with HC-067047 caused an increase in core body temperature at ambient temperature of 26 and 30°C, but not at 22 and 32°C. At 26°C, HC-067047-induced hyperthermia was accompanied by increase in oxygen consumption (an index of thermogenesis). Furthermore, rats chemically stimulated with TRPV4 agonist choose colder ambient temperatures and the cold-seeking behaviour after thermal stimulation (28–31°C) was inhibited by TRPV4 antagonist. Our results suggest, for the first time, that TRPV4 channel is involved in the recruitment of behavioural and autonomic warmth-defence responses to regulate core body temperature.
Os materiais didáticos de inglês como língua estrangeira (LE) na prática de professores da escola pública : um convite à formação reflexiva ou à perpetuação do ensino prescritivo?
(Universidade Federal de São Carlos, 2016-02-12) Lucas, Patrícia de Oliveira; Graves, Kathleen; Augusto-Navarro, Eliane Hercules; https://lattes.cnpq.br/5716027350340906; https://lattes.cnpq.br/0974373709067343
This study investigates the pedagogical practices of four EFL public school teachers, when these professionals make use of teaching materials in their classrooms. In their own voices and guided by their own experiences, these teachers were asked to characterize and report how they handle materials while teaching their students. The roles represented by these materials according to the observed practices were also discussed and analyzed in this dissertation, and distilled into metaphors. In order to better understand the relationship between teachers’ practices and teaching materials, the researcher made use of stimulated recall sessions and a reflective interview. These tools were crucial to this research, as they gave the teachers the opportunity to revisit pedagogical practices. This study is ethnographic-based within a qualitative-interpretive paradigm. According to the data presented in this dissertation, we can infer that stimulated recall sessions and a reflective interview were invaluable resources for this research, as both of them contributed to the reflection process, helping teachers to (re)think their own practices and the roles they have in the classroom as professionals. This dissertation also tries to knit together studies related to teacher preparation and teaching materials, as this combination still remains a gap in the teacher education area. Another gap, which this dissertation attempts to address, is the lack of studies that have given voice to teachers, in order to understand their own perspectives on teaching materials. For future research, we would like to deepen and better investigate and undertake studies which focus is on the combination of teacher preparation and teaching materials (conceptualizations and uses), according to teachers’ and also students’ voices.
Abordagens sintéticas visando a preparação de bacterioclorinas de alta conjugação
(Universidade Federal de São Carlos, 2016-02-12) Assis, Francisco Fávaro de; Oliveira, Kleber Thiago de; https://lattes.cnpq.br/3759761373942891; https://lattes.cnpq.br/0182263452298453
Bacteriochlorins are porphyrin derivatives containing two reduced peripheral double bonds (FIGURE 1). These compounds present, as their main properties, intense absorption bands close to the Near Infrared (NIR, 750-900 nm) (FIGURE 1). Such properties make then attractive for studies in photomedicine, solar devices and many others. Since the beginning, this research was focused in the synthesis of new bacteriochlorin derivatives, thus containing conjugated chromophore groups at non-reduced  positions, in order to redshift the absorption bands into the NIR... continues in the text
Um estudo sobre o uso do GeoGebra na aprendizagem de geometria analítica no ensino médio
(Universidade Federal de São Carlos, 2016-02-12) Silva, Girleide Maria da; Utsumi, Miriam Cardoso; https://lattes.cnpq.br/7990278071583200; https://lattes.cnpq.br/3993140998810167
This study investigated, in a quantitative-qualitative approach of a descriptive nature, the influence of Mathematics teaching combined with technological resources in the learning of some contents of Analytical Geometry. The aim of this study was to analyze the extent to which the software GeoGebra contributed to the learning of the content of point and line. Two groups of the daytime period of the 3rd grade of high school participated in the study of a public school in a city of São Paulo. Both classes were submitted to a Sequence of Activities that considered the different Registers of Semiotic Representation, according to Raymond Duval's Theory. The first group (T1), worked with activities in instructional and constructional approaches using GeoGebra, while the other (T2) worked the activities using pencil and paper. The data were obtained from a questionnaire about the participants' profile, a Pre-Test, Intermediate Evaluation and a Post-Test. Group 1 started the sequence with 0.15 points in relation to the average of the participants of Class 2, and ended with 0.71 points, that is, very close. We consider that for the two classes, the concepts were learned, since the averages in the post-test were 7.90 and 7.19, respectively. It was verified that in the questions that approached the abilities of visualization (locate, identify) and construction (trace, represent), Group 1 presented higher averages than the participants of Group 2, however in the questions that required calculation ability, Group 2 obtained better averages . In this way, we consider that GeoGebra contributed to the learning of point and straight contents, favoring the representation of mathematical objects in different registers. However, we believe that it should be associated with other methodologies that account for the students' comprehension and appropriation of calculation ability, which only the use of the software did not contribute to develop.
