Abstract: sweet potato is a versatile vegetable which can be used both as human and animal food. the relatively easy and inexpensive cultivation of this vegetable associated with the crop adaptability to several conditions of soil and climate enable the production of sweet potato by family farmers. the objective of this research was to evaluate production of fresh and dry mass of vines for animal nutrition and productivity and storage quality of roots for human food of sweet potato clones. the experimental design was randomized blocks, containing twelve clones and four replications. sweet potato clones from ufvjm germplasm bank were tested along with the control cultivars brazlandia rosada and brazlandia roxa, harvested six months after planting date. we evaluated the productivity of fresh and dry matter of vines and yield and quality of roots. the best clone was bd-45 with a high yield of fresh mass, dry matter and total and commercial roots, with values of 19.7; 3.3; 32.9 and 29.5 t ha-1, respectively. most genotypes presented roots near the ideal format for the market and good resistance to soil insects, with values near to grade 2.0. significant differences were observed among genotypes for the content of starch, total and reducing sugars. the genotypes showed similar chemical composition, except for the ash content. clones bd-67 and bd-56 showed higher levels of ash than cambraia, and similar to other clones.
“Awareness” or intraoperative perception
Güette-Viana Anamarina
Revista Ciencias Biomédicas , 2012,
Abstract: Introduction: intraoperative perception or intraoperative awareness occurs whenacquisition or explicit memory formation is produced during general anesthesia. Theinadequate anesthetic depth level allows the development of intraoperative memory,therefor the patient can be conscious of facts that took place during a surgical procedureand to be able to narrate this facts.Objective: to do a thematic review to identify the available knowledge about this kind ofevent.Methods: it was done a search of the literature in electronic databases Pub Med, ScienceDirect, OvidSP and Scielo, about epidemiological and clinical studies, systematic reviews,consensus and meta-analysis using the next keywords: Intraoperative perception,anesthetic complications and awakening during the anesthesia. The search left 204 articles.The summaries were reviewed and 50 studies were chosen by conveniences, which wereabout the central subject of the review and which achieved the inclusion criteria.Conclusion: the important prevalence of intraoperative perception is of 0.2 to 2%. Therisk factors have to be present, the diagnosis and an opportune management have to bepresent, just as the actions of prevention. Rev.cienc.biomed. 2012;3(2):306-311RESUMEN:Introducción: percepción intraoperatoria, despertar intraoperatorio o awareness,ocurre cuando se produce adquisición o formación de memoria explícita duranteanestesia general.

La aldea fantasma: Problemas en el estudio del folklore y la cultura popular contemporáneos
Díaz G. Viana, Luis
Revista de Dialectología y Tradiciones Populares , 2003,
Abstract: The author analyzes the problems involved in the study of folklore and popular culture in a contemporary world, transnational and hybrid, aparently different from what the object/subject of study was supposed to be. Nevertheless he argues that the type of urban legends we can gather today through Internet does not differe from the traditional materials, such as leyends, games or mores, since they talk (as they used to) about people tryng to make sense out of an always changing and mixed world. El autor ofrece un análisis de la problemática relacionada con el estudio del folklore y la cultura popular en el mundo contemporáneo, transnacional e híbrido, aparentemente distinto de lo que se suponía que era el objeto/sujeto de estudio tradicional. Sin embargo, argumenta que el tipo de leyendas urbanas que podemos recopilar hoy a través de internet no es diferente de los materiales tradicionales, tales como leyendas, juegos o costumbres; ya que de lo que hablan éstos, al igual que aquéllos, es de las preocupaciones de las personas por dar sentido a un mundo siempre cambiante y siempre en contacto.
Cifrando y descifrando el mundo: la Etnoliteratura, una Antropología desde lo literario
Díaz G. Viana, Luis
Revista de Dialectología y Tradiciones Populares , 2005,
Abstract: The relationship between anthropology and literature, like the more specific between anthropologists and writers, seems rich in both examples and matters of common interest. Yet there are not only agreements between the two realms, but also divergences: those that set apart art from science, coding the world from decoding it. Within this context of multiple interactions, the author follows on some of the proposals advanced by, among others, Manuel de la Fuente Lombo; he advocates an ethnoliterature that is less a subfield of study than a way of understanding anthropological activity: anthropology from the literary. La relación entre antropología y literatura, así como —más concretamente— entre antropólogos y escritores, parece rica en ejemplos y en asuntos de mutuo interés. Pero no todas son coincidencias: existen también las divergencias propias que se dan entre arte y ciencia, entre cifrar el mundo y descifrarlo. Dentro de ese contexto de múltiples relaciones se reivindica aquí —siguiendo algunas de las propuestas ya realizadas, entre otros autores, por Manuel de la Fuente Lombo— la orientación de la etnoliteratura más que como un subcampo de estudio como una manera de entender el quehacer antropológico: la antropología desde lo literario.

Ocnos , 2005,
Abstract: Este trabajo presenta un análisis de laproblemática relacionada con el estudio del folklorey la cultura popular en el mundo contemporáneo,transnacional e híbrido, aparentemente distinto de loque se suponía era el objeto/sujeto de estudio tradicional.El autor argumenta que los diferentes modosde transmisión de la literatura, hoy, están determinandouna pluralidad de la lectura que obliga, desdelas aportaciones del estudio del folklore contemporáneo–como el de las llamadas “leyendas urbanas”–,a reconsiderar el propio concepto de lectura.
Dihedral Reductions of Cyclic DNA Sequences
Marlos A.G. Viana
Symmetry , 2015, DOI: 10.3390/sym7010067
Abstract: The data-analytic methodology of dihedral reductions for cyclic orbits of distinct-base codons is described both in terms of Fourier analysis over the dihedral groups and in (algebraically equivalent) terms of canonical projections. Numerical evaluations are presented for discrete and continuous scalar data indexed by cyclic orbits.

Olimpiadas y Copa Mundial de Fútbol: Competencias deportivas o instrumentos políticos?
García Reyes, Karina G.
CONfines de relaciones internacionales y ciencia política , 2007,
Abstract: Este artículo analiza, a través de un enfoque geopolítico, el trasfondo de las Olimpiadas y de la Copa Mundial del Fútbol. Para determinar de qué manera podrían ser estos eventos deportivos instrumentos geopolíticos del Sistema Internacional, se revisarán los aspectos que envuelven las próximas Olimpiadas a realizarse en China en 2008, así como el Mundial de Fútbol, en Sudáfrica en 2010. Se contextualizan los motivos de los países que se postularon para ser sedes, sus finalidades y posibles beneficios. Se sostiene que los Juegos Olímpicos y la Copa Mundial de Fútbol son instrumentos políticos internacionales utilizados por los Estados para perseguir sus intereses geopolíticos.This paper analyzes the setting of the Olympic Games and the FIFA World Cup employing a geopolitical approach. To identify in which waythese international sports events are geopolitical instruments of the International System, I present a revision of different elements involved in the selection of China and South Africa as respective hosts of the Olympic Games of 2008 and the World Cup of 2010, such as the motives, goals and possible benefits of these two countries. In this way, I sustain the thesis that the Olympic Games and the World Cup are political instruments used by the States to pursue their geopolitical interests.
AVALIA O IN VITRO DO SêMEN CAPRINO RESFRIADO, COM OU SEM CENTRIFUGA O DO PLASMA SEMINAL E DILUíDO EM LEITE DESNATADO-GLICOSE E TRIS-GEMA DE OVO

Ciência Animal Brasileira , 2006,
Abstract: O objetivo deste trabalho foi comparar in vitro quatro tratamentos para o resfriamento de sêmen caprino, a partir de 32 ejaculados de quatro bodes, submetidos aos diluidores tris-gema de ovo e leite desnatado-glicose, e processados com ou sem centrifuga o do plasma seminal. O sêmen foi resfriado e conservado a 4o C durante 48 horas.Os resultados foram expressos em média e desvio padr o e submetidos a ANOVA (P<0,05) para a análise estatística (SPSS – vers o 11.0). Nas amostras leite desnatado-glicose sem (T1) e com (T2) centrifuga o e tris-gema de ovo sem (T3) e com (T4) centrifuga o, após 48 horas de resfriamento,obtiveram-se as médias de 33,00; 30,68; 40,62 e 46,78 para motilidade (%) e de 2,23; 2,34; 2,65 e 3,25 para vigor (0-5).Quanto às patologias de acrossoma (%) e de cauda (%),após 48 horas de conserva o a 4o C, obtiveram-se as seguintes médias: 5,16; 5,94; 3,81; 4,47 e 16,25; 12,38; 15,34;11,47, respectivamente, para as amostras T1, T2, T3 e T4. Os diferentes tratamentos n o alteraram o pH (p>0,05). Conclui-se que o diluidor tris-gema de ovo preservou melhor(p<0,05) a motilidade, o vigor e a patologia de acrossoma, do que o leite desnatado-glicose. A remo o do plasma seminal, por sua vez, n o influenciou (p>0,05) as características seminais avaliadas, exceto em rela o à patologia de cauda. PALAVRAS-CHAVE: Caprino, centrifuga o, diluidor, resfriamento, sêmen.
