The effectiveness of using frozen sheep semen in artificial insemination programs requires the development of extenders and freezing protocols that will increase pregnancy rate of inseminated females. This work aimed to survey the main extenders, additives and external and internal cryoprotectants that have been employed to improve the maintenance levels of sperm parameters after the freezing-thawing process. Better rates of post-thawing sheep sperm viability may be obtained with changes in the freezing extender composition, whether by the adjustment of its components or by introducing additives that inhibit the occurrence of sperm changes during the cryopreservation process. Thus, the possible changes proposed must take into consideration the intrinsic characteristics of ram semen and the individual variability among animals. It is important to emphasize that the sperm cryopreservation effectiveness requires that all process steps are conducted in an integrated manner, to maximize the fertility rate of frozen ram semen.

Aiming to contribute to understanding the Brazilian academic production on literacy, theses and dissertations on the subject, completed between 1965 and 2011, are analyzed. Situating them in the historical process of constitution of literacy as an object of study, since the 19th. century, beyond the political and historical context of origin in the 1960s, the following contexts are focused, especially from the 1980s, when begins the process of expansion in terms of amount of this academic production and geographic diversity as well as areas of expertise of the graduate programs in which they were defended. While these advances confirm the importance of approaches that consider the interdisciplinary and multifaceted character of literacy, there are contradictions that present significant challenges to researchers seeking both understand the permanence of motivations and pragmatic purposes as to proposing new themes, objects, theoretical and methodological aspects for the development of new research that are lacking, as diagnosed needs and desired progress, scientifically and socially.

This paper presents the emergence of knowledge-criminals criminal character of oppositional discourses to biologists and to the ideals of social defense, denouncing the criminal policies of discriminatory bias that still permeate the administrative practices of conflict. To this end, we examine the precepts of Critical Criminology revolutionary scenario that emerged in the 60s. His propositions denounced emphatically that social control was exercised by class interests and that the criminal policies were a reflection of capitalist domination extended to the criminal area. Accordingly, the present knowledge of such criminology, whose critical analysis culminated in the drafting of an alternative program for the management of the crisis of contemporary legalcriminal: the minimum criminal law and its proposed alternative sentences.

We report here a study about the application of a formal teaching strategy about heat and temperature concepts applied among high school students. The strategy belongs to a research trend which deals with epistemological analogies and has an innovative character related to the students’ preparation for rational debates between conceptions and/or rival theories, using didactical rational reconstruction (DRR) which aims to help scientific concepts rational learning. We investigate the outcomes of this preparation and students’ conceptual development, analyzed through a qualitative-interpretative methodological approach.

Football is a sporting phenomenon that unites the collective to individual, because besides the needs of teamwork, it requires several physical individual abilities. The unpredictability of each match turns it into a fascinating and unique sport. Indeed, this is the most popular and admired sport in all over the world, covering a huge amount of fans and practitioners. Curriculum documents are a new and unprecedented fact in history of Physical Education, so it sought as study object investigate and analyze is being treated in many curriculums proposes of seven Brazilian States (Goiás, Maranhão, Pernambuco, Rio de Janeiro, Rio Grande do Sul, Sergipe e São Paulo) and the Distrito Federal. This study has a qualitative character, using documentary research, because it consists by analyze of curriculum documents. As results, stands out the difference between guiding principles in curriculums. However, all of them are based in a new perspective of Physical Education. With regard to the objectives, was evidenced a consensus among the documents examined, which target as Physical Education objective the formation of critical and autonomous individual, besides your insertion in body culture movements, body culture or movement culture. The results showed that all documents, except of Distrito Federal, mention football as content, only Pernambuco, Sergipe and São Paulo showed a further deepening in the theme. Thus, it is believed that it is essential for a better unfolding of football in Physical Education classes a understanding by the students about this sport, not just as a mere act of running after a ball, but as a social phenomenon broad and contextualized
