Grazielle Machado, Fernando Santos, Douglas Faria, Taiane Nunes de Queiroz, Flávia Zinani, José Humberto de Queiroz, Fernando Gomes
Natural Resources (NR) , 2018, DOI: 10.4236/nr.2018.95011
Abstract: Brazil is the world largest producer of sugarcane (Saccharum officinarum) leading to a great generation of residues such as bagasse and straw, which represent two thirds of sugarcane energetic potential. Regarding these residues energetic potential, it is interesting to study their application in biorefinery processes. Thus, this work aimed at performing a chemical characterization of sugarcane straw and bagasse from RB867515 cultivar grown in Rio Grande do Sul-Brazil aiming at their use as feedstock in biorefinery processes. The obtained results were compared to data from other states and it was possible to conclude that edaphoclimatic conditions of Rio Grande do Sul have little influence in sugarcane residues chemical composition. Sugarcane bagasse presents larger potential for energetic use because of its volatiles content (74.82%) slightly higher than straw (68.90%), besides its high lignin content (21.85%) and higher calorific value (18.70 MJ/kg). Both sugarcane residues produced in Rio Grande do Sul have potential use as substrate in the obtainment of high value-added products from their cellulosic fractions (41.30% and 37.25%, respectively). The evaluation of energetic and chemical potential of sugarcane bagasse and straw produced in Rio Grande do Sul leads to the conclusion that these materials have high potential for use as feedstock in biorefineries.

Abstract: from an epistemological analysis of psychoanalysis, this theoretical study aims to approach the theme of psychoanalysis' scientificity and its immediate consequence to psychoanalysts' formation. this study is an abstract of the third chapter, as well as parties of the final considerations of the master's dissertation called: the openings, the middlegame and endgame in the freud's technical recommendations (1911-1915): and epistemological analysis. therefore, it was possible to indicate a freudian demand for psychoanalysis as a science. then, the appearance of a new professional, divorced from medical knowledge, was also vindicated. this way, it is acceptable to conclude that an initial formation in psychology is necessary, although not sufficient, to the formation of a psychoanalyst who works with the clinical approach, according to freud's teachings.

Abstract: Outbreaks of hepatogenous photosensitivity in cattle in Brachiaria decumbens pastures has been associated with Pithomyces chartaraum spores or with lithogenic saponins in pastures. The objective of this work was to evaluate the laboratorial aspects of the hepatic alterations of cattle fed with Brachiaria brizantha and B. decumbens mix and Andropogon gayanus grass, as well as their correlation with the live weight gains. Fifty bulls were divided into two groups of 25 animals and fed, from weaning to slaughter, with one distinct type of grass. During 30 months and every 60 days blood samples were collected from all the animals, and they were weighed and clinically examined. Samples of the grasses were also collected in the same periods. The amount of P. chartarum spores and concentration of lithogenic saponins from the pastures were determined for a subsequent comparison with the clinical biochemistry results. Any animal showed clinic alterations, weight gains, however, were greater in the A. gayanus group. Hemoglobin concentration, hematocryte levels and erythrocytes number, total and indirect bilirubin were correlated with weight gains. Cattle fed with Brachiaria spp. e Andropogon gayanus showed similar hematological and hepatic function profiles. During the experimental period, independent of the grass type ingested, an increase of AST, GGT and bilirrubin was observed also with an absence of clinical signals suggesting a presence of sub-clinical chronic hepatic alteration. KEY WORDS: Aspartate aminotransferase, gama glutamyltransferase, photosensitivity, saponin, sporidesmin. A fotossensibiliza o hepatógena em bovinos vem sendo associada a fatores como esporidesmina produzida pelo fungo Pithomyces chartarum e saponinas litogênicas das pastagens, e o consumo de capim Brachiaria tem sido responsabilizado pela ocorrência dessa enfermidade. Avaliaram-se os aspectos laboratoriais das altera es hepáticas de bovinos alimentados com capim Brachiaria brizantha e B. decumbens em uma mesma pastagem e Andropogon gayanus, correlacionando-as com o ganho em peso. Cinquenta bovinos foram divididos em dois grupos de 25 animais, alimentados com um dos dois gêneros de capim do desmame ao abate. Durante trinta meses foram realizadas colheitas das amostras de sangue, pesagem e exame clínico dos animais a cada sessenta dias aproximadamente. Do mesmo modo, colheram-se amostras das gramíneas nos mesmos períodos. A quantidade de esporos do fungo P. chartarum e a concentra o de saponinas litogênicas das pastagens foram determinadas para compara o com a bioquímica clínica. N

Abstract: comprehensive assessment of students' academic performance plays an important role in educational planning. the aim of this study was to investigate variables that influence student's performance in a retrospective sample including all undergraduate students who entered in a brazilian dental school, in a 20-year period between 1984 and 2003 (n=1182). demographic and educational variables were used to predict performance in the overall curriculum and course groups. cluster analysis (k-means algorithm) categorized students into groups of higher, moderate or lower performance. clusters of overall performance showed external validity, demonstrated by chi-square test and anova. lower performance groups had the smallest number of students in overall performance and course groups clusters, ranging from 11.8% (clinical courses) to 19.2% (basic courses). students' performance was more satisfactory in dental and clinical courses, rather than basic and non-clinical courses (p<0.001). better student's performance was predicted by lower time elapsed between completion of high school and dental school admission, female gender, better rank in admission test, class attendance rate and student workload hours in teaching, research and extension (r2=0.491). findings give evidence about predictors of undergraduate students' performance and reinforce the need for curricular reformulation focused on with improvement of integration among courses.
