Níveis de proteína digestível e energia digestível em dietas para tilápias-do-nilo formuladas com base no conceito de proteína ideal

This study was carried out to determine the best digestible energy and digestible protein ratio in feeds for Nile tilapia (Oreochromis niloticus) juveniles 30.0 +/- 4.21 g) based on digestible amino acids and the ideal protein concept). Twelve rations were formulated with protein levels 22.0; 26.0; 30.0 and 34.0% of digestible protein and levels 3,000, 3,300 and 3,600 kcal/kg digestible energy. The digestible energy/digestible protein ratio was between 8.94 and 15.19 kcal/g. Three hundred and twenty four tilapias were randomly distributed in thirty six 250 L circular tanks at a density of 9 fish/tank, a total of 12 treatments with three replications. After 60 days, there was no significant difference in weight gain, daily weight gain and feed conversion ratio among the studied treatments. A linear increase was observed in fillet yield with increasing digestible protein. With respect to feed cost/kg weight gain, the treatment with 30.0% DP and 3,000 kcal/kg DE presented low cost and better cost effectiveness index. Therefore, it was concluded that digestible energy did not influence the productive performance parameters and that effective feeds can be formulated with DP levels lower than 34% when feeding juvenile tilapias. The ration should be formulated based on the concept of ideal protein.

Ausência de patogenicidade de Xylella fastidiosa da escaldadura da folha da ameixeira na cultivar de pessegueiro flordasun

Xylella fastidiosa associated to plum leaf scald is reported to belong to the same group of the strain that causes the phony disease of peach. Plants of plum cultivars Santa Rosa and Harry Pickstone and peach cultivar Flordasun, grafted on peach rootstock, were inoculated by using buds collected from plum plants severely infected with X. fastidiosa. Peach plants did not develop symptoms of phony disease, after four years in the greenhouse. In contrast, plum plants from both cultivars inoculated either in the rootstock or in the canopy developed leaf scald symptoms. DAS-ELISA tests with antibody against X. fastidiosa and isolation on BCYE medium indicated the presence of the bacterium in plum tissues. These tests were negative for Flordasun peach for both stem and root samples.

As contribuições dos jogos para o desenvolvimento e aprendizagem da matemática em crianças da pré-escola

This research aimed do verify the contribution of the games of rules to the development and learning of the mathematics of a philantropic institution for preschool children – Centro de Educação Infantil Santo Antônio (CEISA) - from March to September 2010. The overall universe comprehends one teacher, one class auxiliary, one trainee, the organization teaching coordinator and twenty six students. The main objective was to explore games as a strategic resource for the development and learning, by searching auxiliary contributions for teaching the mathematics, and ways to wake and keep the interest of the students for the games as tools of development and learning; to identify important points for such development and learning by using games; to detect the difficulties of the students in the process of teaching-learning mathematics; to use games as a moment for fun; to show the teachers the possibilities of using ludic materials as methodic resources and to make interventions, by means of the games, to enhance the process of teaching-learning the matematics, through a qualitative approach, using the interview as instrument by means of an observation and study of case

Entre vanguarda e a participação: a democracia no programa político da esquerda brasileira (1930-1935)

This paper examines the conceptions of democracy in the Brazilian left among 1930-1935, in particular those expressed in the manifestos of the National Liberative Alliance (ANL) and the texts written by Luis Carlos Prestes, Virgínio Santa Rosa and Caio Prado Jr. I argue that the Brazilian left started from a common troubled field, according to which land concentration represented the biggest obstacle to genuine political expression of the Brazilian people. Despite the convergence towards land reform, designed as a sine qua non condition to democracy in Brazil, the left has developed two different answers to the practical implementation of the principle of the people's government: the first, which I call altruist vanguard, which is more emphasized on texts of Virgínio Santa Rosa and Luís Carlos Prestes, and the second, the Republican participacionismo, which is explored on the writings of Caio Prado Jr. and ambiguously in the manifests of the National Liberative Alliance.

Estúdio na estrada

O presente trabalho visa apresentar o processo e resultados do projeto Estúdio na Estrada, concepção de produção musical, que tem como objetivo levar um estúdio móvel até o artista e realizar todas as atividades relacionadas com a gravação musical. O projeto também contempla os serviços de edição, mixagem e masterização musical, pelo programa ProTools 10. Todo o processo foi dividido em três etapas, de acordo com as cidades do interior paulista as quais o estúdio atuou: Santa Rosa de Viterbo, São Carlos e Ribeirão Preto. O Estúdio na Estrada foi idealizado com o propósito de fomentar o cenário musical do interior paulista e os artistas independentes

Can geometric indices of heart rate variability predict improvement in autonomic modulation after resistance training in chronic obstructive pulmonary disease?

Chronic obstructive pulmonary disease (COPD) is associated with autonomic dysfunctions that can be evaluated through heart rate variability (HRV). Resistance training promotes improvement in autonomic modulation; however, studies that evaluate this scenario using geometric indices, which include nonlinear evaluation, thus providing more accurate information for physiological interpretation of HRV, are unknown. This study aimed to investigate the influence of resistance training on autonomic modulation, using geometric indices of HRV, and peripheral muscle strength in individuals with COPD. Fourteen volunteers with COPD were submitted to resistance training consisting of 24 sessions lasting 60 min each, with a frequency of three times a week. The intensity was determined as 60% of one maximum repetition and was progressively increased until 80% for the upper and lower limbs. The HRV and dynamometry were performed at two moments, the beginning and the end of the experimental protocol. Significant increases were observed in the RRtri (4·81 ± 1·60 versus 6·55 ± 2·69, P = 0·033), TINN (65·36 ± 35·49 versus 101·07 ± 63·34, P = 0·028), SD1 (7·48 ± 3·17 versus 11·04 ± 6·45, P = 0·038) and SD2 (22·30 ± 8·56 versus 32·92 ± 18·78, P = 0·022) indices after the resistance training. Visual analysis of the Poincare plot demonstrated greater dispersion beat-to-beat and in the long-term interval between consecutive heart beats. Regarding muscle strength, there was a significant increase in the shoulder abduction and knee flexion. In conclusion, geometric indices of HRV can predict improvement in autonomic modulation after resistance training in individuals with COPD; improvement in peripheral muscle strength in patients with COPD was also observed.
