The dissertation comprises two studies: the first seeks to problematize the discourse of neutral and objective scientific development and its effects in the construction of the contemporary Brazilian academic knowledge through the writing of an essay supported by social constructionism. Assuming that scientific development is the result of a social construction and thus is not only a fact but a fact full of value that reflects a worldview, evidencing an ideology and revealing the marks of the historical context in which it inserts itself. Therefore, addressing practices such as: the technicality of scientific language, the corporatization of the academy and of many intellectuals who base their practices according to a capitalist logic; academic productivism and the consequent curriculum management, as well as the phenomenon of academic internationalization. Marked by such practices, the dominant discourse associated with scientific development may have as result the academic practices which consist notions of science and scientific criteria supported by the perspectives of neutrality and objectivity, which implies a process of naturalization. The second part discusses the epistemological diversity and scientific criteria presented in publications in journals (2009-2012) in the area of Social Psychology. To formulate this argument, a desk research was conducted associating the publications of research professors of post-graduate programs established in Rio Grande do Sul with Qualis periodicals classifications formulated by the CAPES Program. Thus, this study seeks to contribute to discussions about the social processes that provide epistemological protagonisms. Therefore, throughout this paper we show how the policies can provide homogeneous Qualis scientific criteria which, especially in Social Psychology, provide greater visibility to epistemologies that favor the construction of patterns and a priori expectations for social behavior. / O objetivo deste trabalho ? investigar as diferentes pr?ticas de pesquisa em Psicologia Social no Rio Grande do Sul, no atual cen?rio da P?s-Gradua??o nacional e segundo as pol?ticas de publica??o em peri?dicos institu?das pela Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES). A disserta??o contempla dois estudos: no primeiro busca-se problematizar o discurso do desenvolvimento cient?fico neutro e objetivo e seus efeitos na constru??o do conhecimento acad?mico brasileiro contempor?neo, atrav?s da escrita de um ensaio e com apoio no construcionismo social. Parte-se do pressuposto de que o desenvolvimento cient?fico ? fruto de uma constru??o social e, logo, n?o ? s? um fato, mas um fato carregado de valor que reflete uma vis?o de mundo, evidencia uma ideologia e revela as marcas do contexto hist?rico no qual se inscreve. Dessa forma, abordamos pr?ticas tais como: o tecnicismo da linguagem cient?fica; a empresarializa??o da academia e de muitos intelectuais que pautam suas pr?ticas segundo uma l?gica capitalista; o produtivismo acad?mico e o conseq?ente gerenciamento de curr?culos; bem como o fen?meno da internacionaliza??o acad?mica. Marcado por essas pr?ticas, o discurso predominante associado ao desenvolvimento cient?fico pode ter como efeito pr?ticas acad?micas que comp?em no??es de ci?ncia e crit?rios de cientificidade amparados nas perspectivas da neutralidade e da objetividade, o que implica em processos de naturaliza??o. O segundo estudo discute a diversidade epistemol?gica e os crit?rios de cientificidade presentes nas publica??es em peri?dicos (2009-2012), na ?rea de Psicologia Social. Para fazer essa discuss?o, realizamos uma pesquisa documental que associa as publica??es de professores-pesquisadores de Programas de P?s-Gradua??o institu?dos no Rio Grande do Sul com as classifica??es Qualis peri?dicos formulada pela CAPES. Desse modo buscamos contribuir com as discuss?es sobre os processos sociais que propiciam os protagonismos epistemol?gicos. Logo, ao longo deste trabalho mostramos como as pol?ticas Qualis podem propiciar crit?rios homog?neos de cientificidade e que, especialmente em Psicologia Social, conferem maior visibilidade a epistemologias que favorecem a constru??o de padr?es e expectativas a priori para o comportamento social.

Den största tillgången i företagen är de anställda och deras kompetens. Denna kompetens kan omvandlas till en värdefull tillgång och benämns som intellektuellt kapital. Trots att det finns ökad förståelse för att det intellektuella kapitalet skapar mervärde för företaget finns det hinder med att redovisa detta då det inte får tas upp i balansräkningen. Syfte: Uppsatsens syfte är att analysera huruvida intellektuellt kapital är något som fondförvaltare utvärderar när de gör en investeringsbedömning. Avgränsningar: Begränsningarna är att vi undersöker hur intellektuellt kapital kan vara till fördel för endast fondförvaltare; vi analyserar olika fondförvaltare i deras arbete endast med en investeringsbedömning. En sista avgränsning är att vi valt att inte tillfråga de fondförvaltare som inte utvärderar intellektuellt kapital aktivt i sina investeringsbedömningar. Metod: Vi har utgått från en kvantitativ metod och har genomfört en enkätundersökning för insamling av material. Resultatet har vi analyserat utifrån den teori som vi tagit upp i det teoretiska kapitlet. Ansatsen är av abduktiv karaktär åt det deduktiva hållet då vi har studerat existerande teorier och fallstudier inom ämnet. Resultat, slutsatser: Svenska fondanalytiker lägger inte särskilt stor vikt på intellektuellt kapital när de utvärderar och analyserar ett företag. Grunden till detta är för det första att det är svårt att mäta trovärdigheten av intellektuellt kapital när företagen själva sammanställer och redovisar detta utan att kontrolleras av någon utomstående part. För det andra är korrelationen mellan större delen av ett företags strukturkapital och aktiens utveckling på börsen inte påvisbar. Förslag till fortsatt forskning: Ett redovisningssystem för intellektuellt kapital som är lika för alla inom samma bransch möjliggör fortsatt forskning inom ämnet med syftet att finna en analysmetod som påvisar eller dementerar förändringen av ett företags intellektuella kapital med företagets aktierörelse på börsen.

I here present a combined AVO analysis of P-P and P-S reflection data whose objective is to improve the identification of lithology by estimating the specific values of Poisson's ratio, [sigma], for each rock formation in a given geological model, rather than a contrast between formations. Limited knowledge on the elastic parameters of a given rock formation and difficulty regarding the availability and processing of P-S data constitute hindrances of lithology identification. Considering that ocean bottom seismology (OBS) has aided in solving the problem of P-S data availability, limited information on elastic parameters is still a challenge, and the focus of this thesis. The present analysis is based on Zoeppritz' solution for the P-P and P-S reflection coefficients, RPP and RPS, with a slight modification. We used the normalized P-S reflection coefficient; i.e., R'PS = RPS / sin [theta] for [theta] > 0, instead of RPS, where [theta] is the incident angle. By normalizing RPS, we avoid dealing with the absence of converted S-waves at small incident angles and enhance the similar linear behavior of the P-P and normalized P-S reflection coefficients at small angles of incidence. We have used the linearity of RPP and R'PS at angles smaller than 35 degrees to simultaneously estimate the average VP/VS ratio, the contrasts of P- and S-wave velocities, and the contrast of density. Using this information, we solve for Poisson's ratio of each formation, which may enable lithology discrimination. The feasibility of this analysis was demonstrated using nonlinear synthetic data (i.e., finite-difference data). The results in estimating Poisson's ratio yielded less than 5 percent error. We generalize this new combined P-P and P-S AVO analysis for dipping interfaces. Similarly to the nondipping interface case, our derivations show that the amplitude variation with offset (AVO) of P-P and P-S for a dipping interface can be cast into intercepts and gradients. However, these intercepts and gradients depend on the angle of the dipping interface. Therefore, we further generalize our analysis by including a migration step that allows us to find the dipping angle. Because seismic data is not available in terms of RPP and R'PS, this process includes recovery of reflection coefficients after migrating the data and correcting for geometrical spreading, as done by Ikelle et al. (1986 and 1988). The combination of all of these steps, namely geometrical-spreading correction, migration, and AVO analysis, is another novelty of this thesis, which leads to finding the specific values of Poisson's ratio of each rock formation directly from the seismic data.

Do ponto de vista metodol?gico foram entrevistados 26 discentes e realizada an?lise documental referentes a leis e documentos da pol?tica educacional em n?vel federal e dos organismos internacionais. A luta por amplia??o do acesso ? universidade est? na agenda dos movimentos sociais no ?mbito da educa??o, no entanto na conjuntura dos governos de Luis In?cio Lula da Silva (2003 a 2010) e Dilma Rousseff (2011 a 2012) a tend?ncia tem sido seguir as orienta??es dos organismos internacionais e promover expans?o de vagas sem assegurar estrat?gias de perman?ncia compat?veis com as exig?ncias de excel?ncia acad?mica postas, por exemplo, na p?s-gradua??o. Discentes entrevistados acessam o ensino superior e os cursos de p?s-gradua??o e vivenciam dificuldades di?rias para atender com qualidade ?s exig?ncias acad?micas em face de suas condi??es materiais de vida e de trabalho e dos limites da pol?tica de assist?ncia estudantil que tem um perfil de programas e a??es localizadas

Os melhores resultados para as os sinterizados de WC-Ni, foram obtidos para as amostras sinterizadas via SPS a 1350?C, apresentando dureza Vickers (2322 HV) e densidade (97,67 %) superiores as das amostras sinterizadas por sinteriza??o convencional a maiores temperaturas. / In this work WC-Ni composite powders were synthesized by carborreduction of the hydrated ammonium paratungstate (APT) mixture with the nickel nitrate in proportions (5% p.Ni, 10% p.Ni and 15% p.Ni) a low temperature (800 ? C to 950 ? C) and small reaction time (90min to 150min) in a single synthesis process. The powders were characterized mainly by X-ray diffraction, scanning electron microscopy (SEM), dispersive energy spectroscopy (EDS), X-ray fluorescence (FRX), particle size analysis and (BET) and measures of magnetization, coercivity and remanence. The study of crystallite size was obtained from the X-ray diffractograms of post-composites, using the Scherrer equation. A factorial experimental design 23 with three central points was carried out to evaluate the influence of the synthesis conditions on the response variables (crystallite size). The synthesis parameters evaluated in this work were: reaction time (90min, 120min and 150min), synthesis temperature (800 ? C, 850 ? C and 900 ? C) and concentration of nickel by weight (5% p.Ni, 10 % P.Ni and 15% p.Ni). It was possible to produce nanometric WC-Ni composite powders in the desired proportions with the desired purity, with a mean crystallite size varying from 24.2 nm to 38 nm, with a surface area ranging from 24.6m?/g to 46.7 m?/g. The powders presented morphology with particles of varied sizes and shapes, quite agglomerated and also presented a good dispersion and homogenization of the phases. The specific characteristics of these nanometric materials provide their use for both the hard metal in catalytic reactions.Therefore, the composite powders obtained in this work were applied in the production of WC-Ni hard metal by solid and liquid phase sintering using conventional sintering and Spark Plasma Sintering techniques for comparison purposes. In the sintered samples the measurements of Vickers hardness and density by pycnometry were performed. We also performed XRD, SEM and EDS analyzes with mapping. The best results for the sintered WC-Ni were obtained for the sintered samples via SPS at 1350?C, showing Vickers hardness (2322 HV) and density (97.67%) higher than the samples sintered by conventional sintering at higher temperatures. / 2018-08-23

The sample was composed by 253 patients underwent abdominal surgeries. The results showed a total of 63.63% females between 38 and 47 years of age (21.34%); illiterates (21.73%); married (64.03%), living in Natal and surroundings (67.97%) and Catholics (74.30%). In their first assessment, 84.19% showed postoperative pain; the pain was considered light in 18.97% of them, moderate in 21.74% and severe in 43.48%. The mean number of descriptors chosen through the McGill Questionnaire Pain was 10.78 (DP= 6.09) and pain rating 23.65 (DP= 15.93). The descriptors selected with higher frequency were: sickening pain (69.01%), tired (65.25%), thin (62.44%), bored (58.69%), ardor (46.48%), pointed (38.50%) and colic (35.21%). In their second assessment, 57.71% of patients didn t relate any postoperative pain and 42.29% were still complaining about the pain. After taking analgesic medication, just 41.90% of patients who had complete pain relief. The Pharmacological groups most used were: simple analgesic (37.86%), weak opioids (32.98%), AINES (19.85%) and strong opioid (9.31%). It was not found a significant postoperative pain variation related to the sexes, religion and kind of surgery. It was concluded there were a high level in the number of patients with postoperative pain, mainly in a severe scale. Less than half of patients had the pain relief. Then, it was observed there was not coherence between the pain intensity and the analgesic it was used. To solve or relieve this kind of problems is necessary a permanent education to the health professionals who works in this area / Estudo explorat?rio descritivo, com abordagem quantitativa, desenvolvido entre fevereiro e maio de 2010, com o objetivo de avaliar a dor dos pacientes submetidos a cirurgias abdominais em um Hospital Universit?rio, em Natal/RN; identificar a localiza??o e a intensidade dolorosa mensurada pela Escala de Estimativa Num?rica; analisar a dor nas dimens?es sensorial-discriminativa, motivacional-afetiva e a cognitivo-avaliativa, utilizando o Question?rio para dor McGill; relacionar o processo ?lgico com a idade, sexo, religi?o e tipo de abordagem cir?rgica; identificar a efetividade da medica??o utilizada no al?vio da dor p?s-operat?ria. A amostra constou de 253 pacientes submetidos a cirurgias abdominais. Os resultados mostraram que 63,63% eram mulheres, entre 38 e 47 anos (21,34%); n?o alfabetizados (21,73%), casadas (64,03%), procedentes da grande Natal (67,97%) e cat?licas (74,30%). Na primeira avalia??o, 84,19% apresentaram dor p?s-operat?ria; 18,97% apresentaram dor leve; 21,74% moderada e 43,48% severa. A m?dia do n?mero de descritores escolhidos atrav?s do Question?rio de Dor McGill foi 10,78 (DP= 6,09) e o ?ndice de dor 23,65 (DP= 15,93). Os descritores escolhidos com maior frequ?ncia foram: dor enjoada (69,01%), cansativa (65,25%), fina (62,44%), aborrecida (58,69%), ardor (46,48%), pontada (38,50%) e c?lica (35,21%). Na segunda avalia??o, 57,71% pacientes n?o referiram dor p?s-operat?ria e 42,29% continuaram com queixas de dor. Apenas 41,90% dos pacientes tiveram sua dor totalmente aliviada ap?s administra??o do analg?sico. Os grupos farmacol?gicos mais utilizados foram os analg?sicos simples 37,86%, opi?ides fracos 32,98%, AINES 19,85% e opi?ides fortes 9,31%. N?o encontramos rela??o significativa entre a vari?vel dor p?s-operat?ria com o sexo, religi?o e tipo de abordagem cir?rgica. Conclu?mos que houve uma alta preval?ncia de dor p?s-operat?ria, principalmente a de intensidade severa. A dor foi efetivamente aliviada em menos da metade dos pacientes. Dessa forma, percebemos que n?o existia coer?ncia entre a intensidade da dor do paciente e o analg?sico administrado para o seu al?vio. A educa??o permanente dos profissionais de sa?de dever? ser uma das a??es mais eficazes para evitar ou minimizar a ocorr?ncia desse evento

No munic?pio de Diamantina/MG, apresenta relevante import?ncia socioecon?mica pelo grau de aceitabilidade de seus frutos e multiplicidade de uso. Todavia, ainda n?o existem variedades recomendadas para o plantio comercial, sendo que para a forma??o de novos pomares ? necess?rio dispor de material que re?na caracter?sticas favor?veis. O presente trabalho teve como objetivo realizar a caracteriza??o biom?trica e f?sico qu?mica de frutos e fisiol?gica de sementes de acessos de jabuticabeiras ?Sabar?? em Diamantina/MG, visando identificar materiais promissores para uso comercial e para futuros trabalhos de melhoramento gen?tico. De acordo com os resultados obtidos, os acessos de jabuticabeira (Myrciaria jabuticaba Berg), apresentam variabilidade para todas as caracter?sticas estudadas. Foi evidenciada a adequa??o de suas caracter?sticas biom?tricas e f?sico-qu?micas para consumo in natura e agroindustrial, sendo as melhores os frutos provenientes dos acessos A1, A2, A4, A22 e A23, enquanto os frutos dos acessos A8, A9, A13, A16 e A17, det?m de caracter?sticas antioxidantes naturais, podendo ser utilizada pela ind?stria aliment?cia. Atrav?s das caracter?sticas fisiol?gicas das sementes, os acessos A13, A20 e A17 se destacaram como fonte de material propagativo, por deter de maior vigor perante as caracter?sticas avaliadas. Os descritores rela??o DL/DT, n?mero de sementes, rela??o SST/ATT da polpa, umidade da polpa,di?metro longitudinal, flavon?ides da casca, rela??o SST/ATT da casca, tanino da casca, umidade da casca, ATT da polpa e poliembrionia, foram os que mais contribu?ram para a forma??o de grupos de acessos com caracter?sticas fenot?picas similares identificadas pela an?lise de agrupamento. Poucos s?o os estudos dessa esp?cie, deve-se ainda realizar um conjunto maior de pesquisas que parte da bot?nica e da gen?tica, incluindo acessos superiores, formas de propaga??o e melhor desenvolvimento, incorpora??o de produtos agroind?strias e seus valores comerciais. / Disserta??o (Mestrado) ?

Considering the lack of information about this type aimed at working with the genetic divergence among accessions of jabuticabeira ?Sahara? through biometric descriptors and physico-chemical and physiological fruit with seed in order to subsidize the Genetic Improvement program for jabuticabeira in the city of Diamantina. It has been used multivariate analysis of variance (MANOVA), the criterion of Tocher and principal component analysis to determine the genetic divergence. Among the 32 descriptors evaluated, the principal component analysis allowed the elimination of 21, because they show redundant and/or little influence. The remaining 11 were responsible for 92.31% of the total variation. Tocher's grouping method applied to the matrix of Euclidean shape average of 3 groups, with the largest of which comprised 22 accessions. According to the results of the class of jabuticabeira "Sahara" there is a significant variability among the characteristics. Descriptors DL, DT, seed number, SST/ATT pulp, pulp moisture, longitudinal diameter, the bark of the flavonoids, SST/ATT bark, bark tannins, the moisture from the skin, pulp and ATT that contributed polyembryony a characterization of the accessions jabuticaba. Jabuticaba?s hits considered a satisfactory variation for future improvements and conservation organizations of the species. It is expected to use the most promising access due to the greater disparity has a better average performance of these accesses.

Breast milk is the only source of this vitamin for children that are exclusively breastfed. Analysis of vitamin A in mother s milk is important because its concentration is related to maternal vitamin A status and to its ingestion by the mother during pregnancy. The aim of the present study was to assess the effect of maternal supplementation with retynil palmitate on the concentration of colostrum retinol under fasting and postprandial conditions. A total of 149 nursing mothers were recruited at the Janu?rio Cicco Maternity School (Natal, Brazil) and allocated to two groups: Comparison (n = 69) and Test (n = 80). Blood and colostrum (in fasting and postprandial conditions) samples were collected up to 24hs after delivery. Serum retinol and colostrum levels were analyzed by high-performance liquid chromatography. The serum retinol level of 41.6 ? 12.7?g/dL (mean ? standard deviation) indicates adequate biochemical nutritional status. Colostrum retinol level was not influenced by serum retinol levels under any of the conditions established. In the colostrum, the retinol concentration in the unsupplemented test group was 67.3 ? 37.7 ?g/dL under fasting and 80.3 ? 35.1 ?g/dL under postprandial conditions (p<0.05), showing an increase of 19.3%. In the supplemented test group the values were 102.6 ? 57.3 ?g/dL and 133.4 ? 78.3 ?g/dL under fasting and postprandial, respectively (p<0.05), representing an increase of 30%. Considering that under fasting conditions most of the vitamin A transported to the milk originates in the retinol binding protein (RBP), the postprandial increase in colostrum retinol suggests a different transport mechanism of retinol to maternal milk from that performed by RBP. This situation becomes more evident under supplementation conditions. / Vitamina A ? importante em muitos processos essenciais no corpo e sua defici?ncia resulta em severas conseq??ncias para a sa?de dos seres humanos. O leite humano ? a ?nica fonte dessa vitamina para crian?as que s?o amamentadas de forma exclusiva. A an?lise da vitamina A no leite materno ? importante, porque a sua concentra??o neste fluido est? relacionada com o estado de vitamina A materno e com a ingest?o desta vitamina pela m?e durante a lacta??o. Assim, o objetivo do presente trabalho foi avaliar o efeito da suplementa??o materna com palmitato de retinila sobre a concentra??o de retinol no colostro em condi??es de jejum e p?s-prandial. Para isso, foram recrutadas 149 nutrizes saud?veis da Maternidade Escola Janu?rio Cicco (Natal- RN), sendo os grupos Compara??o 69 e Teste 80. Amostras de sangue, colostro em jejum e colostro p?s-prandial foram coletadas at? 24hs ap?s suplementa??o. As concentra??es de retinol no soro e colostro foram analisadas por cromatografia l?quida de alta efici?ncia. A concentra??o s?rica de retinol de 41,6 ? 12,7?g/dL (m?dia ? desvio-padr?o) indica estado nutricional bioqu?mico adequado. A concentra??o de retinol no colostro n?o foi influenciada pelos n?veis s?ricos de retinol, em nenhuma das condi??es estabelecidas. No colostro, a concentra??o do retinol no grupo teste sem suplementa??o foi de 67,3 ? 37,7 ?g/dL no jejum e de 80,3 ? 35,1 ?g/dL no p?sprandial (p<0,05), evidenciando um aumento de 19,3%. No grupo teste suplementado os valores foram de 102,6 ? 57,3 ?g/dL e 133,4 ? 78,3 ?g/dL no jejum e p?s-prandial, respectivamente (p<0,05), representando um aumento de 30%. Considerando que no jejum a maior parte da vitamina A transportada ao leite tem sua origem atrav?s da prote?na transportadora de retinol (RBP), o aumento no retinol do colostro p?s-prandial sugere um mecanismo de transporte do retinol para o leite materno distinto daquele realizado pela RBP. Tal situa??o fica mais evidente em condi??es de suplementa??o.
