The aim of this study was to compare four genetic groups of sheep on the carcass and meat quality traits. Thirty-three contemporary and unrelated male lambs, all of single birth were used in the experiment, being thirteen from the Santa Inês (SI) breed, seven from the Brazilian Somali breed (BS), six from the Morada Nova (MN) breed and seven from the ½ Dorper - ½ Morada Nova (F1) crossbreed. The genotypes SI, BS and F1 presented similar performances in relation to hot and cold carcass weights, which values were 10.76±0.53kg and 10.46±0.52kg for SI, 9.20±0.73kg and 8.99±0.71kg for BS, and 9.35±0.73kg and 9.13±0.71kg for F1, respectively. The BS had a better hot carcass yield (47.10±0.88%) and cold carcass yield (46.00±0.87%). Better carcass conformation was observed in SI and F1 (2.73±0.12 and 2.50±0.17, respectively) while the BS presented a better finishing (3.29±0.20). The average for the rib eye area (REA) was 9.94±0.49cm², 8.66±0.67cm², 7.18±0.72cm² and 9.8±0.67cm², and for the carcass compactness index (CCI) it was 0.17±0.01kg/cm, 0.17±0.01kg/cm, 0.11±0.01kg/cm and 0.16±0,01kg/cm, for SI, SB, MN and F1, respectively. There were no significant differences between SI, BS and F1 regarding REA and CCI. Although, in general, the MN presented a relatively lower performance than the other genotypes, this breed had similar carcass yields and fat thickness when compared to SI and F1 and similar conformation and REA in comparison to the BS. Regarding meat quality, no differences were observed between genotypes, except for redness and cooking losses. It is concluded that no one group had a higher or lower performance in all traits analyzed. Moreover, for the management conditions employed in this study, there was evidence of greater specialization in meat production for genotypes SI, BS and F1 when compared to MN, although there are no substantial differences between the four groups regarding meat quality.

A anurofauna do estado de São Paulo, nas últimas oito décadas, tem sido foco do estudo de importantes grupos de pesquisa em anfíbios anuros. Porém, pesquisas realizadas com comunidades na área da Depressão Periférica do centro-oeste paulista ainda são escassas. A fim de trazer novas informações sobre essa região, nosso objetivo foi inventariar a anurofauna de uma área na Depressão Periférica, associando os resultados com dados da literatura e confrontando os mesmos com aqueles conhecidos para a anurofauna no altiplano da Cuesta de Botucatu. O inventário foi realizado a partir dos dados obtidos em 24 dias de amostragem, decorridos 13 meses de coleta (dezembro de 2008 a dezembro de 2009). Os anuros foram amostrados em potenciais sítios reprodutivos, pelos métodos de encontro visual e busca auditiva. Foram registradas 29 espécies distribuídas em 12 gêneros e seis famílias. Apesar da maioria das espécies serem predominantemente de áreas abertas, consideramos a riqueza elevada, e associamos essa riqueza à existência dos remanescentes de mata nos interflúvios. Entretanto, apesar da presença desses remanescentes, a ocorrência de espécies associadas exclusivamente a essas áreas foi pequena, se comparada aos fragmentos no altiplano, fato que aparentemente está associado às diferenças existentes entre os fragmentos contidos nos interflúvios e os fragmentos do altiplano. A atividade dos anfíbios foi concentrada no período quente e úmido, diminuindo à medida que se aproxima o ápice da estação fria e seca. Com base na análise de similaridade, observou-se a formação de agrupamentos com alta sobreposição. Entre esses agrupamentos, destacaram-se aqueles formados por espécies com atividade de vocalização prolongada, mas que diferiram quanto ao período de maior atividade (início e final da estação chuvosa) bem como, aqueles constituídos por espécies com período de vocalização mais curto, restrito a poucos dias, e que também diferiram no mês de pico de atividade (início e final da estação chuvosa). Com isso acreditamos que as diferenças quanto à distribuição temporal dos organismos da comunidade sejam importantes na partilha de recursos e no ajuste das espécies, fato que contribuiu para o elevado número de anfíbios observados e na coexistência dos táxons na área de estudo.

The Tahiti lime appears very susceptible to attack by post-harvest diseases, primarily by the fungi Penicillium and Phomopsis, and also because of its high sensitivity to storage at low temperatures. In order to reduce such damage, the present study aimed to verify the efficiency of heat treatment and disinfection of pathogens in the prevention of post-harvest chilling injury of this cultivar and to compare this treatment with other products using the conventional fungicides. The heat treatments were studied with hot-water temperatures ranging between 48 and 56° C. Water at room temperature was used as a control treatment. After treatment, the fruits were kept under cold temperature at 10° C and RH 90% for about 45 days. For comparison, three other treatments were carried out simultaneously, one using imazalil, one with baking soda, and a third with sodium carbonate, these three products being applied by baths in cold water. Two groups of fruit were evaluated, one treated by immersion considering pathogens coming from the field and another by inoculation with spores of the previously isolated pathogens. For the evaluation of physical and chemical parameters of fruits, determinations were made of the skin color, texture, weight loss, size, juice yield, soluble solids, total acidity and vitamin C content. The determination of the sensitivity of the fruit to cold was made by their exposure at temperatures inducing cold damage. The design was a randomized block design with nine treatments, analyzed by the Statgraphics statistical package. Heat treatments, especially at 52° C, were shown to be more promising in the control of pathogenic fungi and cold damage, surpassing the conventional fungicides. No changes were found in the intrinsic and extrinsic parameters in relation to the application of the different treatments.

PURPOSE: To determine the effect of sour flavor and cold temperature on oral transit time during swallowing. METHODS: Participants were 52 subjects (28 male and 24 female) with ages between 50 and 80 years (median=66 years), after ischemic stroke involving right or left side damage and mild to moderate oropharyngeal dysphagia. Videofluoroscopy was performed to analyze the swallowing times. Each subject was assessed during swallowing of a paste consistency bolus offered in 5 ml spoons, with a total of four different stimuli (natural, cold, sour and sour-cold). After the exam, the oral transit time was measured using specific software. The oral transit time (starting at the beginning of the bolus movement in the mouth) and the total oral transit time (starting at the moment that the bolus is placed in the mouth) were measured. RESULTS: The association between sour and cold stimuli caused a significant decrease of oral transit time and total oral transit time. CONCLUSION: Sour flavor and cold temperature reduced oral transit time in stroke patients.

The previous knowledge of the infection process and pathogens behavior, for evaluating the physiological potential of maize seeds, is essential for decision making on the final destination of lots that can endanger sowing. This research was carried out in order to study the minimum period required for maize seeds contamination by Fusarium graminearum Schwabe and Fusarium verticillioides (Sacc.) Nirenberg, as well as these pathogens influence on seed germination and vigor, by using the cold test. Three maize seeds hybrids, kept in contact with the pathogens for different periods, were evaluated with and without surface disinfection. After determining the most suitable period, new samples were contaminated by F. graminearum and F. verticillioides, under different infection levels, and subjected to germination tests in sand. The cold test was conducted with healthy and contaminated seeds, at different periods, in a cold chamber. The contact of maize seeds with F. graminearum and F. verticillioides for 16 hours was enough to cause infection. F. graminearum and F. verticillioides did not affect the maize seeds germination, however, F. graminearum reduced the vigor of seeds lots.

The aim of this study was to evaluate citric acid application with or without chitosan on the maintenance of the quality of litchi 'Bengal'. It was used litchi on mature maturation stage. After selection, fruits were immersed for one minute on the solution of citric acid and chitosan: [1]Control - without immersion; [2] citric acid 300g L-1, [3] citric acid 300 g L-1 + chitosan 0,3%, [4]citric acid 300 g L-1 + chitosan 0,6%, [5] citric acid 600 g L-1, [6] citric acid 600 g L-1 + chitosan 0,3%, [7] citric acid 600 g L-1 + chitosan 0,6%. Chitosan of low molecular weight and deacetylation degree of 75,58% (Sigma - Aldrich®) were used. After immersion, fruits were put to drain the excess of solution. Then, they were stored in cool chamber at 5ºC, previously sanitized, for 20 days. The experiment was conducted following a completely randomized design, with a factorial scheme composed by seven coating solutions and five sampling dates. Every five days were evaluated: loss of fresh mass of fruits; color; content of anthocyanins and the activity of peel enzymes polyphenoloxidase and peroxidase. It was verified that the solution of citric acid 600 g L-1, associated or not to chitosan, and the combination of chitosan 0,3% to 300 g L-1 of citric acid were the most efficient to maintain the quality of litchi 'Bengal' for 20 days at 5ºC.

This work aimed to evaluate the carcass yields, commercial cuts and non-carcass components of Santa Inês lambs fed with 30, 40, 50 or 60% of oldman saltbush hay with concentrated. Were used 32 castrated lambs at 8 months old and initial body weight of 22 + 1.97kg, housed individually and slaughtered after 60 days of feedlot. The weights of hot and cold carcass decreased linearly with the inclusion of saltbush hay in the diet, however, there was no effect for true carcass yield and commercial cuts: shoulder (19.26%), neck (8.52%) ribs (26.57%) and leg (33.88%). There was a linear decrease for ribeye area and fat thickness when the level of hay in the diet increased. The weights and yields of skin, liver, heart, kidneys with perirenal fat, omental and mesenteric fats decreased linearly with the inclusion of hay in the diet, while the content (%) of gastrointestinal tract increased. The increased proportion of saltbush hay in the diet of lambs provided adequate true carcass yield and commercial cuts, however, reduces the ribeye area and fat thickness, important measurements in the qualitative evaluation of the lamb's carcass.

In the post Cold War period, in the security field, has increased the mechanisms of cooperation and coordination among the Latin American states, in the context of so called confidence-building measures. These arrangements presented as important and efficient tools of political-strategic articulation and assist in the maintenance of peace in the region. The paper presents some considerations about the current scenario in terms of security and defense in Latin America. Initially, presents concepts of security and defense and perceptions of threats by the states. Then, discusses the mechanisms of cooperation and coordination in security have been established on the American continent in the periods of the Cold War and post Cold War. Finally, presents considerations regarding the scenario and the prospects of security issues in the region.

The implantation of military regimes in South America, from the mid-1960s, happened in the context of the Cold War. As a result, both the occurrence of military coups and the plans and actions for the national defense of the Southern Cone States occurred following the logic of that period and the concept of hemispheric defense preached by the United States, with priority in combating the so-called internal subversion. Thus, the need to combat the “internal enemy” has led these countries to participate in hemispheric mechanisms or create his own arrangements for coordination. The article starts from the conflict hypothesis used by the military governments in their military planning to analyze the actions carried out against leftist movements, including coordination between the governments of the Southern Cone. The understanding of the defense concepts against Soviet communism allows us to understand that the groups placed against the military governments were seen as a danger to the State and, in that “state of war”, the means justified the ends.
