Considerações sobre a presença e características do tema água nas Propostas Curriculares para o ensino de Química/2009, do Estado de São Paulo

This study sought to raise the water issue is addressed in the teaching of chemistry in public schools through the notebooks Curricular Proposal of the State of Sao Paulo. First we tried to do a survey of knowledge related to construction of the concept of historical perspective, the physical and chemical properties, their importance to man and the particulars of the national curriculum for this subject. The methodology used was qualitative, descriptive and documentary. We analyzed the books for the first, second and third marking periods and the three series (the 4th book had not yet been distributed). As expected the first scenario, the proposed curriculum addresses the topic in greater depth in only one of the notebooks of the second year of high school. The approaches are no longer linked to health issues and the environment, cross-cutting issues considered by the NCP and important for students to make associations between the chemical content and their daily lives. We conclude that the contract should be evaluated by teachers and that their use should be involved in drawing up a plan that takes into account the aspects that seem incomplete. We also emphasize that although the proposal is interesting from the standpoint of teaching, teachers need training to its full use in the classroom

Etnomatematica: psicologia aplicada à educação matemática

Investigations in ethnomathematics show that there are several cultural forms of mathematics, mathematics different dominant. Currently, most research in ethnomathematics aim an ethnographic study of anthropological or cultural groups. However, there is a strong need for studies in ethnomathematics is to target the pedagogical action, involving the teachinglearning practices. So the big challenge for researchers in ethnomathematics is the development of study and teaching practices in line with the objectives philosophicaltheoretical Program Ethnomathematics

Efeitos da experimentação no cotidiano letivo no ensino médio

In this work, it was studied the effects of the experimentation in the physics teaching. Beginning from the theoretic reference and discussions, the objective was prove the efficiency of researches of this nature related to two main aspects of a class: The aroused interest in the students and the facilitating action on the understanding of the theory. For such objective, using the comparison, it was chosen two distinct classes, but the more similar possible, so that, in one of them, it was showed a tradition class, lectures and in another, a class using experimentation to contemplate the theory. To manage a way to rate these aspects, it was made a conceptual questionnaire, requiring only concepts rather than mathematics and equations, besides specific interviews to rate the opinion of the student related to each method. The observations in classes and of the reactions of the students also were of a big value to analysis. After the experimental class completed, it may analyze and conclude some positive points related to experimental methods: As for the opinion of the students, the approval was big, and the majority opined to this class as being “more interesting”. On the point of view of learning, it had a sensitive improvement of grades, but with more mature answers, deep and autonomous, if looking at a general vision

Genome-wide association study and ancestral origins of the slick-hair coat in tropically adapted cattle

The slick hair coat (SLICK) is a dominantly inherited trait typically associated with tropically adapted cattle that are from Criollo descent through Spanish colonization of cattle into the New World. The trait is of interest relative to climate change, due to its association with improved thermo-tolerance and subsequent increased productivity. Previous studies localized the SLICK locus to a 4 cM region on chromosome (BTA) 20 and identified signatures of selection in this region derived from Senepol cattle. The current study compares three slick-haired Criollo-derived breeds including Senepol, Carora, and Romosinuano and three additional slick-haired cross-bred lineages to non-slick ancestral breeds. Genome-wide association (GWA), haplotype analysis, signatures of selection, runs of homozygosity (ROH), and identity by state (IBS) calculations were used to identify a 0.8 Mb (37.7-38.5 Mb) consensus region for the SLICK locus on BTA20 in which contains SKP2 and SPEF2 as possible candidate genes. Three specific haplotype patterns are identified in slick individuals, all with zero frequency in non-slick individuals. Admixture analysis identified common genetic patterns between the three slick breeds at the SLICK locus. Principal component analysis (PCA) and admixture results show Senepol and Romosinuano sharing a higher degree of genetic similarity to one another with a much lesser degree of similarity to Carora. Variation in GWA, haplotype analysis, and IBS calculations with accompanying population structure information supports potentially two mutations, one common to Senepol and Romosinuano and another in Carora, effecting genes contained within our refined location for the SLICK locus.

A new heterologous fibrin sealant as a scaffold to cartilage repair - experimental study and preliminary results

Autologous fibrin gel is commonly used as a scaffold for filling defects in articular cartilage. This biomaterial can also be used as a sealant to control small hemorrhages and is especially helpful in situations where tissue reparation capacity is limited. In particular, fibrin can act as a scaffold for various cell types because it can accommodate cell migration, differentiation, and proliferation. Despite knowledge of the advantages of this biomaterial and mastery of the techniques required for its application, the durability of several types of sealant at the site of injury remains questionable. Due to the importance of such data for evaluating the quality and efficiency of fibrin gel formulations on its use as a scaffold, this study sought to analyze the heterologous fibrin sealant developed from the venom of Crotalus durissus terrificus using studies in ovine experimental models. The fibrin gel developed from the venom of this snake was shown to act as a safe, stable, and durable scaffold for up to seven days, without causing adverse side effects. Fibrin gel produced from the venom of the Crotalus durissus terrificus snake possesses many clinical and surgical uses. It presents the potential to be used as a biomaterial to help repair skin lesions or control bleeding, and it may also be used as a scaffold when applied together with various cell types. The intralesional use of the fibrin gel from the venom of this snake may improve surgical and clinical treatments in addition to being inexpensive and adequately consistent, durable, and stable. The new heterologous fibrin sealant is a scaffold candidate to cartilage repair in this study.

Undergraduate Scholarship in the College of Arts and Sciences Book of Abstracts 2010

The College of Arts and Sciences proudly presents the eighth issue of the Book of Abstracts, which highlights the work conducted by students in collaboration with faculty mentors. This collection of abstracts represents many hours of scholarly activity in which students further developed their research, critical thinking, and writing skills and engaged in learning well beyond the classroom.
