Neste trabalho, relatamos as propostas que temos efetivado em três disciplinas que abordam conteúdos de Ciências e de Meio Ambiente, em um curso de Pedagogia. Nessas disciplinas, procuramos propiciar o desenvolvimento de práticas investigativas, que articulem conhecimentos de diferentes campos, contribuindo para uma visão integradora da realidade e para a exploração das múltiplas relações entre Ciência, Tecnologia, Sociedade e Ambiente (CTSA). Entendemos que a realização de trabalhos com esse enfoque, durante a formação, pode contribuir para a valorização das áreas de Ciências e Educação Ambiental e de seu ensino por parte dos docentes em formação e, como consequência, para o enriquecimento da prática educativa com crianças nos anos iniciais da escolarização.

A culture of resistance in the semi-arid, expressed by mentalities and values, goes against the economic potential of sheep and goat raising, considered as an inferior activity when compared to the cattle raising, historically linked to social status and prestige. This paper attempts to shed light on aspects that make possible to clarify the roots of the cognitive apparatus that supports this view, resorting to it to the production of relevant authors dealing with the issue of displacement of colonizer and livestock in the hinterlands. Ultimately, it seeks evidence of the influence of the historical process of economic and social organization of space on the present.

As an alternative to improve the adaptation of prefabricated posts in flared canals and weakened roots, the option is for relining prefabricated pin, known as a technique of anatomical post. This technique, which can be made with composite resin increases the adjustment post to the walls of the canal and reduces the cementing line, causing the retaining post is less dependent on the mechanical properties of the cementing agent. This article aims to provide an overview of anatomical posts, specifically in the last two decades, based on studies extracted from Scielo, Scopus and Pubmed, referring to the following terms of MeSH Data Base: custom made fiber post, indirect fiber glass posts, root canal therapy and post and core tecnique. According to the literature review in this article, it can be concluded that this technique has been used by several authors and has been shown effective and promising, it creates an individualized retainer with better adaptation and decreased mechanical imbrication cementing line .

Obesity is the most common nutritional problem in dogs and it can cause various harmful effects on animal health. However, the effect of this condition on systolic blood pressure (SBP) in obese dogs is controversial. The indirect method of measuring PAS is the most commonly used in veterinary medicine for the diagnosis of systemic hypertension, because it is more practical and easy to access. There is little scientific information about the comparison of the two non- invasive methods of measurement of blood pressure in obese dogs. Therefore, the objective of this study was to evaluate the SBP in obese dogs by comparing both indirect methods of measuring blood pressure, with oscillometric and doppler vascular in order to verify the differences in blood pressure values, but also the best method to assess the SBP dogs in this body score condition. The study complain blood pressure measurement of 50 dogs, with were divided in obese dogs with mean body condition score (BCS) of 8.42 +/- 0.50 (n = 25) and dogs with ideal BCS of 4.56 +/- 0.51 (n = 25). At comparison of blood pressure values, SBP values obtained by doppler method (152 +/- 16mmHg) were higher than the oscillometric (136 +/- 11mmHg). Correspondence analysis determined by multivariate statistical analysis showed correlation between body condition and the procedure of the SBP. These findings suggest that the indirect method doppler can better reflect the SBP in obese dogs.

The present study has as its main purpose the investigation of teachers'view concerning the teaching and learning of basketball in Physical Education classes in a school setting. The selected teachers who participated in this survey come from public and private institutions in the city of Volta Redonda, RJ, Brazil, teaching 6th-9th grade classes of elementary school. This was a quantitative and qualitative study with content analysis. Data collection included interviewing 60 teachers who provided their opinions on the issue investigated. Development of basketball was investigated not only as a content for the Physical Education classes, but also as a dimension that goes beyond school boundaries, where that sport plays an important role in society. Joint actions to provide the opportunity for basketball to grow as a content for Physical Education classes may represent a way to describe its implementation in all contexts, although the importance of this discipline in the school setting should not be disregarded in favor of obtaining results in sports competitions.
