Revista Brasileira de Saúde e Produ??o Animal , 2011,
Abstract: The experiment was conducted to evaluate the best level of inclusion of palm kernel cake in massai grass silage by chemical-bromatological, fermentation index and forage value of the silage analysis. The experiment was conducted at Experimental Farm of the School of Veterinary Medicine and Zootec. The treatments were composed by massai grass cut at 40 days, chopped and added to 8%, 16% and 24% of palm kernel cake and the cake without additional treatment. After mixing, the material was compressed in experimental silos, which were opened after 60 days. The experimental design was completely randomized, with four treatments and four replications. Data were analyzed by analysis of variance and regression. The addition of palm kernel cake improve the chemical-bromatological and fermentation index of massai grass silage, beyond increase the forage value of silage. The best level of inclusion of palm kernel cake was 24%, for provided the biggest content of dry matter, crude protein and ether extract, beyond provided the lower content of fibrous fractions and reduction of the values of pH and ammoniacal nitrogen. O experimento foi conduzido com o objetivo de avaliar o melhor nível de inclus o da torta de dendê na ensilagem de capim-Massai com base nos parametros químico-bromatológicos, fermentativos e índice de valor forrageiro.

O melhor nível de inclus o da torta de dendê foi o de 24%, uma vez que propiciou os maiores teores de matéria seca, proteína bruta e extrato etéreo, bem como os menores teores da fra o fibrosa e redu o nos valores de pH e nitrogênio amoniacal.
Complications in the use of local anesthetics: literature review
Cleverson Luciano TRENTO,Cristiano GAUJAC,Edvaldo Fernandes dos SANTOS,Gustavo Danilo Nascimento LIMA
Perspectives in Oral Sciences , 2010,
Abstract: Local anesthesia is the most frequently method of pain control in Dentistry and the use of local anesthetics may cause systemic complications. In order to avoid them, dentists must perform a good anamnesis, use appropriated anesthetic techniques and respect the maximum doses of each local anesthetic. Besides, it is important to have knowledge, equipments and training to achieve a correct diagnosis and treat the complications that may occur during dental treatment. This paper aims to review the literature about the most often systemic complications in clinical dentistry caused by the use of local anesthetics.

Leonardo dos Santos Lima
Journal of Modern Physics (JMP) , 2016, DOI: 10.4236/jmp.2016.713148
Abstract: The interaction between an electron with a three-dimensional domain wall was investigated using the Born’s expansion of the S scattering matrix. We obtain an influence of the scattering of the electron with the ferromagnetic domain wall in the spin wave function of the electron with the aim to generate the knowledge about the state of the electron spin after the scattering. It relates to the recent problem of generation of the spin polarized electric current. We also obtain the contribution of the electron-wall domain interaction on the electric conductivity \"\", through the wall domain, where we have obtained a peak of resonance in the conductivity for one value of \"\" .

Abstract: In order to recognize and anticipate customer’s requests, reinforce and manage the communication and operational flows, analyses of which are the services that the consumers demand to the energy companies are extremely important. To improve each relationship channel and to recognize the customers’ profile, expectations and needs, it has been necessary to reinforce the operational efficiency concerning costs and agility. Operational effectiveness answering the demands is pursued, considering the amount of services offered and generated by relationship channels, communication facilities and operational conditions provided by the companies. A huge amount of data had to be organized to represent this scenario and forecast the relationship. To represent it, models were created to monitor and predict customers’ requirements based on historical and online data. There were established regional resources availability, weather conditions, problems concerning the energy distribution grid, as well as the motivation of the customers to use alternative medias or relationship channels. The big data treatment techniques were used in order to provide the necessary agility to achieve the monthly/hourly volume of data (millions of registers per month) and permit communication clusters’ views.
As muitas faces da Economia Política da Comunica o no Brasil
Luciano Correia dos Santos
Comunica??o, Mídia e Consumo , 2008,
Abstract: A Economia Política da Comunica o (EPC) é ainda uma jovem debutante entre as disciplinas que integram as ciências da comunica o, assim tratadas nos vários eventos científicos que procuram enquadrar os fen menos dessa área para tratá-los com os métodos da pesquisa acadêmica. Jovem que ganhou status de GT (Grupo de Trabalho) próprio na Compós, a Associa o Nacional dos Programas de Pós-gradua o em Comunica o, essa linha conquista cada vez mais terreno, seja pela amplitude das pesquisas desenvolvidas seja pela prolífica produ o dos autores associados. é o caso de Valério Cruz Brittos e Adilson Cabral , que acabam de lan ar Economia política da comunica o: interfaces brasileiras. O livro é uma coletanea de artigos de vários pesquisadores relacionados com a área de estudo, mas que atuam em segmentos distintos, incluindo os dois organizadores, percorrendo trechos que v o desde a própria conceitua o da Economia Política da Comunica o e as tens es exercidas dentro do campo científico, passando por abordagens sobre a indústria cultural, novas tecnologias e as plataformas digitais, além do conflituoso terreno das políticas de comunica o e as legisla es específicas. S o textos baseados nas principais mesas do Encontro da Ulepicc-Brasil, realizado na Universidade Federal Fluminense, em Niterói (RJ), de 18 a 20 de outubro de 2006. No primeiro texto do livro, Suzy dos Santos mostra a que veio a EPC nos estudos da comunica o, lembrando que o servi o prestado pela linha é fruto de consenso: é imprescindível adotar um olhar crítico para retratar empiricamente os objetos das comunica es, sob a luz de um propósito também crítico, o da necessidade emergencial de participa o ativa da pesquisa científica no processo de constru o de um ambiente de comunica es efetivamente democrático (p. 15). Ao analisarem a indústria cultural e sua inser o no capitalismo contemporaneo, Valério Brittos e Jo o Miguel apontam a tendência (lamentável) dos estados de deixar a cultura e o comunicativo entregues às lógicas dessa indústria, ficando, conseqüentemente, sujeitos às invers es do capital. Assim, o capitalismo deixa de ser apenas do domínio econ mico para determinar a política e a cultura, ou seja, penetra em todas as dimens es das pessoas. Por esta via, é cada vez mais do que um modo de produ o, para estabelecer-se como um processo civilizatório, onde a subsun o do simbólico é sucessiva, contínua e inconclusa (p. 41). Os autores discutem os resultados desse processo dentro do ambiente tecnológico, as estratégias adotadas pelas firmas do setor e o predomínio da publicidad

Abstract: Forty-eight goats naturally infected with gastrointestinal nematodes were randomly divided into four groups (=12): negative control (G1) (untreated), positive control (G2) (treated with doramectin, 1 mL/50 Kg b.w.), and G3 and G4 treated with 2.5 and 5 mg/Kg b.w. of a leaf aqueous extract of Caesalpinia pyramidalis (CP). Fecal and blood samples were regularly collected for the evaluation of fecal egg count (FEC), hematological and immunological parameters to assess the anthelmintic activity. In treated animals with CP, there was noted a significant reduction of 54.6 and 71.2% in the mean FEC (<0.05). An increase in IgA levels was observed in G3 and G4 (<0.05), during the experimental period, suggesting that it was stimulated by the extract administration. In conclusion, the results showed that CP provoked a protective response in infected animals treated with them. This response could be partly explained by the CP chemical composition.
