Abstract: the objective of this experiment was to evaluate the yield and quality of the carcass and meat cuts from kids of both sexes, slaughtered at three different ages, aiming to use animals from dairy herds. forty-one kids were used, from three breed groups: alpine, ? boer ? alpine (? ba) and ? boer ? alpine (? ba), which were slaughtered at 60, 90 or 120 days of slaughter age. the animals were raised in a feedlot system. the following carcass traits were evaluated: carcass weight, commercial yield, conformation, subcutaneous fat, internal and external length, leg length, rump perimeter, thoracic depth, rump width, compactness, meat cut yield and tissue proportion. meat tenderness was evaluated by means of the warner-bratzler shear force. data were analyzed as an incomplete factorial arrangement (2 sexes x 3 breed groups x 3 slaughter ages), in a complete randomized design. as age increased, so did carcass weight and characteristics, as well as the weight of edible carcass components and commercial yield. the boer crossbreds showed higher leg compactness and less bone compared to the alpines. no difference in meat tenderness was observed for breed group, age or sex.

Abstract: the objective of this trial was to evaluate performance (weight and weight gain), body measurements, feed conversion, and production costs of purebred (alpine) and crossbred [? boer + ? alpine (? ba) and ? boer + ? alpine (? ba)] goat kids at different ages (60, 90 and 120 days). therefore, 41 kids in a feedlot system were used in this study. data were submitted to analysis of variance using the tukey test for comparison of means. no difference in performance was observed among the three different groups of animals (alpine, ? ba, and ? ba). body condition score was greatest in ? ba kids, which may represent additional profit to producers if animals are sold alive. as expected, most body measurements increased with age. body measurements and weight at birth, 60 and 90 days of age were all greater on males than females. in addition, alpine males were heavier than females at 120 days of age. they also gained more weight from 30 to 60 days when compared to females. the lowest production cost (kg of feed per kg of weight gain) was observed at 90 days of age.

Abstract: O presente trabalho objetiva discutir o papel que os jogos de linguagem possuem no desenvolvimento de gêneros textuais orais, também responsáveis pela inser o da crian a em práticas letradas. Para tanto, discutiremos as no es de jogos de linguagem e de gêneros textuais, buscando identificar nesses fen menos as diversas vias de acesso ao letramento como processo multidimensional. Com isso, adotaremos uma investiga o de cunho interpretativista, observando dados referentes a um corpus coletado em sala de aula da Educa o Infantil, com crian as na faixa etária de quatro anos de idade. Nossos resultados apontam a presen a de jogos de linguagem nos gêneros orais que se apresentam em sala de aula. Isso nos leva a crer que as práticas letradas demandam o uso de jogos de linguagem, uma vez que eles viabilizam a diversidade de formas de utiliza o da língua.

Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104411
Abstract:
The imbalance between oxidant molecules and antioxidant agents is characterized as oxidative stress (OS) and may lead to severe damage to the organism. In contrast, the physical training of aerobic and resistive character promotes increases of the antioxidant response, resulting in a balance and/or minimizing damage. Therefore, the objective of the study is to verify the effect of aerobic training, resistive training and concurrent training on oxidative stress of Wistar rats. Methods: To perform the experiment, 40 Wistar rats were subjected to eight weeks of training. The animals were distributed into 4 different groups: control, aerobic, resistive and concurrent (combination of aerobic and resistive protocols in the same section) an h/day, five days/week, for eight weeks. At the end of the experimental period: the antioxidant enzymes (catalase, glutathione peroxidase and superoxide dismutase), biomarkers of oxidative stress (TBARs and H2O2) as well as the activity of reduced and oxidized glutathione were analyzed. Results: Regarding the markers, TBARs and H2O2 trainings were not effective in promoting significant reduction. In contrast, the three training protocols caused an increase in SOD and GSH-GPx enzymes. Conclusion: Therefore, we concluded that both training protocols promoted benefit to the organism, because they caused the increase of antioxidant enzymes without disturbance in the pro-oxidant markers.

Abstract: O presente trabalho tem por finalidade tra ar apontamentos acerca da compatibilidade entre as inova es trazidas pela Lei no 11.705/08 ao Código de Transito Brasileiro e as garantias processuais presentes na Constitui o Federal. ainda que haja notória importancia social, sobretudo no que tange à diminui o dos acidentes de transito, resta razoável delimitar em que medida tal política pública preserva as garantias constitucionais dos condutores de veículos parados pela blitzen da Lei Seca, especialmente em rela o à utiliza o do etil metro enquanto meio de aferi o da alcoolemia do motorista. The present essay has the objective to point out the compatibility of the innovations brought by the Law no 11.705/2008 to the Brazilian Traffic Code and the process guarantees present in the Federal Constitution. Even tough there is a clear social relevance, mainly aiming at reducing the traffic accidents, it is reasonable to question until what point the measure preserves the constitutional guarantees of the drivers of vehicles stopped by Lei Seca [Anti-DUI Law] Blitzes, specially relating to the use of the breathalyser as method for measuring the BAC [Blood Alcohol Content] of the driver.
