Comportamento ingestivo de cordeiros alimentados com torta de macaúba

Avaliaram-se os efeitos de diferentes porcentagens (0, 10, 20 e 30%) de inclusão da torta de macaúba (TM) no comportamento ingestivo de 24 cordeiros Santa Inês, com média de cinco meses de idade e peso vivo de 23,9kg, distribuídos em delineamento em blocos ao acaso, com quatro tratamentos e seis repetições, durante 60 dias de confinamento. Foram avaliados os tempos médios despendidos com alimentação, ruminação (TR), ócio (TO), tempo de mastigação total (TMT), eficiência de alimentação (EA MS e EA FDN) e eficiência de ruminação, além do número de bolos ruminados (NBR) e número diário de mastigações merícicas (MMnd). A adição de TM à dieta aumentou linearmente o TR, TMT, NBR, MMnd e EA FDN e reduziu de forma linear o TO, em consequência do maior teor de fibra em detergente neutro das dietas com o coproduto. Mesmo com o aumento no TMT, não foi verificada diferença no consumo e na eficiência de ruminação e alimentação da matéria seca, possivelmente em razão da baixa efetividade de fibra da TM, demonstrando o potencial de utilização desse coproduto na dieta de ovinos em crescimento.

Proximate composition of guariroba (Syagrus oleracea), jerivá (Syagrus romanzoffiana) and macaúba (Acrocomia aculeata) palm fruits

This study aimed to characterize the pulp and kernel of guariroba (Syagrus oleracea), jerivá (Syagrus romanzoffiana) and macaúba (Acrocomia aculeata) palm fruits, through their proximate composition, carotenoids contents and tocopherol composition. The three kernels showed to be composed mainly of lipids and proteins, as the three pulps, of carbohydrate and fiber. In the kernels the levels of lipids ranged from 45.17 to 56.37% and proteins from 15.46 to 28.61%. In the pulps the total fiber content ranged from 20.26 to 26.98%. The pulps also presented a significant amount of ash, which represents a significant mineral content, especially in the guariroba (5.16%). Moreover, the pulp oils showed higher carotenoids and tocopherol contents. The jerivá pulp oil contained carotenoid and tocopherol on average 1219 μg/g and 323.50. mg/kg, respectively. The consumption of the whole fruit, pulp, and kernel supplies important quantities of many necessary nutrients for human diet, including vitamins A and E. © 2011 Elsevier Ltd.

Um olhar bakhtiniano sobre a questão do dialogismo X monologismo: Macabéa e a linguagem no processo de (des)constituição do eu

Bakhtin, during the development of his theories, focused matters concerned to language, also taking account of the vital importance of its role in the formation of men. Thus, he was concerned in treating language not only as a simple mean of communication among people, but also as a social and crucial activity for the development of human beings. According to that and regarding the Bakhtinian concepts of alterity and dialogism in this paper, we intend to verify some aspects related to Macabéa, the protagonist of the novel entitled A Hora da Estrela, by Clarice Lispector, as well as her communication with the outside world, via language, trying to clarify, into that process, elucidative elements which attest her diffi culty in interacting with the world that surrounds her, besides the consequent de(constitution) of her own identity.

Extração e caracterização qualitativa do óleo da polpa e amendoas de frutos de macaúba [Acrocomia aculeata (Jacq) Lodd. ex Mart] coletada na região de Botucatu - SP

The international energy situation indicates to the depletion of oil reserves in the short term. Brazil, considering its potential, has sought through public policy, encourage the study of alternative forms of energy. Many of these forms are based on sub-products and agricultural products, especially the ethanol industry for fuel purposes. Another alternative of vegetable origin, most recently discussed, would be the production of fuel oil called biodiesel. The study aimed to extract and measure the pulp oil production of macaúba palm [Acrocomia aculeata (Jacq) Lodd. ex Mart], collected in Botucatu (SP). In addition, the qualitative analysis of the pulp and almond oil are determined. The results showed low productivity in oils, compared to the reported for macauba natural populations of Minas Gerais. The qualitative analysis of the macauba pulp shows to be rich in long chain fatty acids, while the almond have significant amounts of lauric acid.

Controle do cupim de montículo (Isoptera: Termitidae) de pastagem com fungos entomopatogênicos

The objective of this study was to evaluate the control of mound-building termites (Isoptera: Termitidae) by entomopathogenic fungi (Metarhizium anisopliae and Beauveria bassiana). We developed two experiments, with two copies of application in three sizes of nests. The first was installed in the Salto Macauba farm and second in the Laboratory of Plant Protection at the State University of Mato Grosso do Sul. The first experiment consisted of five repetitions, each nest an experimental unit, with treatments in a factorial 2 (fungi) x 2 (tests) x 2 (type of spraying) + 1 control, distributed completely at random in the area. The treatments were: 1) control - no implementation, 2) Metarril M103 (M. anisopliae) - 10 g/mound-dusting, 3) Metarril M103 - 10 g/mound - via net, 4) Metarril M103 - 15 g/mound-dusting, 5) Metarril M103 - 15 g/mound - via net, 6) Boveril B102 (B. bassiana) - 10 g/mound - dusting, 7) Boveril B102 - 10 g/mound - via net, 8) Boveril B102 - 15 g/mound-dusting and 9) Boveril B102 - 15 g/mound-via net. The testing of mortality were made spraying of the laboratory with the field measurements performed in compliance with the same separation of the nests. The results suggested that the road dust (dosage of 10 g) of the fungi studied showed higher mortality of nests of small size (53%). B. bassiana (Boveril) (10 g) gave 80% mortality of C. cumulans when applied to nests of small size.

Possibilidades de diálogo entre o conceito de ideologia em Bakhtin e a teoria das representações sociais

Introducing the theoretical trajectory of social representations theory, outline here the parallel between this theory in social psychology and the Bakhtinian concept of ideology. Both approaches include individual and society as inseparable and views the array of social construction of knowledge forms, related to day-to-day, or composed by formal record of science, as state, religion etc. With this interdisciplinary study, although limited, we hope to contribute to a better understanding of theories that have made important contributions to social psychology, linguistics, ethnography, cultural studies etc.
