Efeito do parceiro social sobre a resposta comportamental ao ambiente novo em sag��i comum (Callithrix jacchus)

Algumas pesquisas demonstram que a presen��a de um parceiro social durante uma situa����o de risco modula a resposta ao estresse, atenuando seus efeitos negativos. Neste estudo, 8 d��ades de machos e 8 de f��meas de sag��i comum (Callithrix jacchus) foram expostos a um ambiente novo, sozinhos e acompanhados de um parceiro de mesmo sexo e idade. Quando submetidos a um ambiente novo em companhia de um animal de mesmo sexo, os machos apresentaram um perfil mais filiativo enquanto as f��meas foram mais competitivas entre si. Os resultados mostram que a resposta comportamental �� sexualmente dim��rfica, e que machos e f��meas utilizam diferentes estrat��gias quando confrontados com situa����es desafiadoras no ambiente natural Abstract Some researches demonstrate that the presence of a social partner during a challenging situation modulates the stress response, decreasing its negative effects. In this study common marmoset (Callithrix jacchus) males and females were exposed to a new environment, alone or in companion of a social partner of the same sex and age. When submitted to new environment in companion of a same-sex social partner males showed more affiliation whereas females performed agonistic behaviors. The results show that behavioral response is sexually dimorphic and that males and females used different strategies when facing challenging situations in natural conditions

Vem ouvir o verso de teu cantador : amos, cantadores e toadas no Boi-Bumb�� Caprichoso Bel��m/PA

This thesis aims to investigating the cantadores and the toadas in the Boi Bumb��, debating questions which put together around the construction and performance of amo s and cantador s role in the Boi Bumb�� Caprichoso of Bel��m-PA city and exploring the extent of toadas its characteristics, functions, the uses that are made of theirs and the relations that establishes between them and the cantadores. The problematic of the research consisted on analysing what the amos, cantadores and toadas represent in the whole context of boi-bumb�� plays in Bel��m, nowadays. Considering this perspective, I tried to identify on Boi Caprichoso the most meaningful expressions which were related to toadas and how the roles of amo and cantador were performed. Participative observation, ethnical research, open and semistructured interviews were used as research methods. The role performances on Boi Caprichoso plays an essential part on the playing realization, highlighting themselves as pivotal characters. These performances, characterized by the vocal presence, also highlighted the size that toadas occupy in the whole play, and pointed the way for an emerging model of presentation, in which both toada and cantador appear as central figures

Efeito sacietog��nico de um novo inibidor de tripsina da pa��oca do amendoim com aumento plasm��tico de colecistocinina (cck)

Obesity is increasing, reaching epidemic levels in many regions of the world. Studies have shown that consumption of peanuts influences on weight control and this influence may be due to the action of trypsin inhibitors sacietog��nica that condition increased plasma colescistocinina (CCK). Moreover, the peanut has other health benefits, and these assignments are guaranteed to increase their production and consumption of several of its products, including the pa��oca peanut. The aim of this study was to identify the presence of a trypsin inhibitor in pa��oca peanut and evaluate its effect on food intake, weight gain and histomorphological changes in swiss mice (n = 8) and Wistar rats (n = 6). Experimental diets were prepared based on the AIN-93G and supplemented with tack or peanut trypsin inhibitor partially purified pa��oca peanut (AHTI). After each treatment, the animals were anesthetized and euthanized, their bloods were collected by cardiac puncture for the determination of CCK and other biochemical parameters (glucose, triglycerides, total cholesterol, high density lipoprotein, low density lipoprotein, glutamic-pyruvic transaminase, glutamic oxaloacetic transaminase and albumin) and their pancreas removed for histologic and morphometric analysis. The supplementation with pa��oca peanut and the AHTI showed a decrease of body weight gain and food intake in both mice and rats, due to the satiety, since the animals showed no evidence of impairment of nutritional status conditioned by consumption the AHTI. There were also observed biochemical or morphological important when compared with controls. However, AHTI led to increased secretion of CCK, a peptide sacietog��nico. Thus, these results indicate that AHTI present in pa��oca peanut, is able to enhance the secretion of plasma CCK and thereby reduce the weight gain associated with lower food intake of experimenta animals

Estudos e propriedades mec��nicas de um novo tipo de bloco cer��mico h��brido para edifica����es em alvenarias estruturais

This dissertation presents a hybrid ceramic block the use of which reside in the buildings executed with walls. Initially, we conducted a survey on the requirements and / or norms prevailing in Brazil about structural ceramic blocks, making use of the experiences in other countries. This work seeks new materials and / or products in order to maintain or increase the compressive strength of the ceramic blocks, without neglecting the other properties. Then was collected materials (clay and crushed powder) and an approach on the characterization, through fluorescence, Mineralogy, vitrification curve and characterization of these materials used in the manufacture of the blocks by Ray Diffraction "X" and SEM. Subsequently it was made, numbered and measured dimensions of about 150 bodies of the test piece (hybrid ceramic blocks in small sizes) with varying percentages of 0%, 5%, 10% and 15% substitution of crushed clay powder. After sintering of the bodies of the test piece at temperatures of 900oC, 1000oC 1100oC and with a heating rate of 5oC/minuto and level of 1 hour, the samples were submitted to the tests (compressive strength and water absorption) and calculated their retractions, which were subsequently carried out the analysis of the results according to the criteria and parameters required by Brazilian legislation and standards in force

Novo m��todo para estimativa do gradiente de fratura para po��os de petr��leo

The development of oil wells drilling requires additional cares mainly if the drilling is in offshore ultra deep water with low overburden pressure gradients which cause low fracture gradients and, consequently, difficult the well drilling by the reduction of the operational window. To minimize, in the well planning phases, the difficulties faced by the drilling in those sceneries, indirect models are used to estimate fracture gradient that foresees approximate values for leakoff tests. These models generate curves of geopressures that allow detailed analysis of the pressure behavior for the whole well. Most of these models are based on the Terzaghi equation, just differentiating in the determination of the values of rock tension coefficient. This work proposes an alternative method for prediction of fracture pressure gradient based on a geometric correlation that relates the pressure gradients proportionally for a given depth and extrapolates it for the whole well depth, meaning that theses parameters vary in a fixed proportion. The model is based on the application of analytical proportion segments corresponding to the differential pressure related to the rock tension. The study shows that the proposed analytical proportion segments reaches values of fracture gradient with good agreement with those available for leakoff tests in the field area. The obtained results were compared with twelve different indirect models for fracture pressure gradient prediction based on the compacting effect. For this, a software was developed using Matlab language. The comparison was also made varying the water depth from zero (onshore wellbores) to 1500 meters. The leakoff tests are also used to compare the different methods including the one proposed in this work. The presented work gives good results for error analysis compared to other methods and, due to its simplicity, justify its possible application

Novo sistema de aplica����o de drogas em cirurgias oftalmol��gicas

The topical corneal application of antimitotic mitomycin-C (MMC) during refractive surgery is still characterized by a lack of standardization and considerable empirism. For this reason the creation of a system capable of reliable drug delivery represents a beneficial innovation for patients submitted to these procedures. Objective: Elaborate a new MMC delivery system during the transoperatory period of photorefractive keratectomy (PRK) followed by patent application. Methods: The project consists of an in vitro experimental study to create an MMC (0.02%) release system. The drug was impregnated in sterile Whatman�� 41 paper filter discs with a diameter of 8 mm. After drying, the discs were applied to antibiogram plates seeded with Staphylococcus epidermidis (American Type Culture Collection ATCC 12228), followed by the addition of a drop of sterile water. At the end of 1 minute, the discs were removed and the plates incubated for 48 hours at 35oC. Mean drop volume in the collyrium flasks was measured using analytical balance weighing. The inhibition halo (mm) was correlated with the MMC impregnated into the disc. After completion of the invention design a patent application was lodged at the National Institute of Industrial Property. Results: The correspondence between MMC-produced inhibition halos indicated that a dose of 16��g was ideal for impregnating into the discs. The mean drop volume obtained from the collyrium flasks was 37.7 ��L. A minute after the application of one drop of balanced saline solution, the system released an adequate concentration for PRK surgery. Conclusion: A new MMC delivery system was created for transoperatory application in photorefractive keratectomy (PRK). Publication of the patent application (number PI 0704739-8) gives the authors exclusive intellectual property rights. The study was sponsored by Ophthalmos Ind��stria e Com��rcio de Produtos Farmac��uticos S.A. (S��o Paulo-SP, Brazil) and received the indispensable scientific contribution of researchers from the fields of Pharmacy, Medicine, Biology, Statistics and Law, characterizing the work as multidisciplinary, in accordance with norms established by the Postgraduate Health Sciences Program of the Federal University of Rio Grande do Norte (UFRN)

Os filhos evang��licos do novo caldeir��o do diabo: a convers��o religiosa na penitenci��ria de alca��uz

The theme of the research is inserted at a field of intersection between the Sociology of Religion and Sociology of Violence, having as the general objective study the sociological meaning of the conversion of prisoners that lives at the biggest prison (Prison of Alca��uz) of Rio Grande do Norte to the evangelical churches. The research is justified, because Brazil shelter the fourth greater arrested population arrested of the world, with projections indicating that it can turn the greatest in 2034. Besides, this study about religious conversion of prisoners to the Social Sciences is too important, because is a theme little developed in Brazil and deserves attention, one time that as the arrested people as the evangelicals are in expansion in our country. Starting from the precedent observations, we guide ourselves by the following problematic of research: the religious practice in Alca��uz presents a mere instrumental perspective, where the actions of prisoners converted was on purpose oriented to conquest material or symbolic privileges; or purely religious, where seek a moral renovation? To develop the work, the scientific methodology adopted was exploratory and explanatory, using the Goffman��s theory about total institutions and presentation of self, and Blumer��s doctrine relating to Symbolic Interacionism and the Story life method, besides considerations about evangelical religion. Having this theoretical basis, was accomplished the Field research, when were made interviews and applied questionnaires to 11 Jailer Agents, 31 prisoners, Director and Vice-Dictor (in November, 2011), the coordinator of social projects of the prison and the coordinator of evangelization at the prisons in Rio Grande do Norte. As results, it was seeing in Alca��uz that the prisoners can be separated in two groups: the one of Pavilions and other one of the Medical Section. The Pavilions are branded for managerial and structural problems, where are found idle prisoners in collective cells and with a historical of escaping attempts, mutinies and murders. The Medical Section has some individual cells or destined for two people, besides few collective also, and the prisoners work and have a more disciplined behavior, there isn t escapes or rebellions and that, for these reasons end for have more confidence from the Administration. About the presence of evangelical prisoners, most are at Medical Section, where exist a specific place to the cults (what doesn t at Pavilions). At the end, the conclusion is that the prisoner that says himself evangelical in Alca��uz, although can be seeing with distrust about your real conversion, he gets win a trust vote and until the opposite being demonstrated in other words, that he is not hiding himself behind the bible to divert the vigilance of Direction and practice disciplinary faults without make any suspicions, is treated with more respect and has more opportunities live at Medical Section; have work, that most of times is paid and guarantee the homologation of your payment of penalty with work, besides other benefits, diminishing his time in jail

Bio��tica e biodireito: interfaces e conflu��ncias

This thesis addresses the development of technoscience in times of transnational globalization and highlights the vulnerability of the discourse of social progress, which may be replaced by evidence of social risk before the artificiality of nature and humanity. That demands an ethical and legal responses to events that impose the necessity of an ethical control in biotechnology research involving human beings contributing to the rise of Bioethics and Biolaw as fields of knowledge. This theme is studied from a multidisciplinary perspective seeking a dynamic dimension in the interpretation of research data reconnecting Social Sciences to Legal Sciences (Biolaw) and to Philosophy (Bioethics), in order to obtain answers to the problems posed. The objective delimited is to examine the interfaces between Biolaw and Bioethics, in order to observe the confluence of these areas of knowledge. Biolaw is considered as a new legal branch derived from the paradigmatic transition of Law and wonders how it will stand before questions resulting of social transformations caused by biotechnological development that endangers humans and society. It is concluded that the relationship between Bioethics and Biolaw is recursive and inseparable and it contributed to the "unthink" of traditional legal model of linear view/reductionist allowing that the "certainties" will be replaced by "possibilities", which comes to enable Biolaw to confront the issues caused by the development of biotechnology that violates physically and morally the human person. It is perceived, therefore, that Biolaw is driven and aided by bioethical reflections and it positions itself before the dilemmas caused by biotechnology in creating, interpreting and applying coercive rules which aims to protect the human being, his offspring and society

A reestrutura����o produtiva e as novas formas de organiza����o do trabalho: a experi��ncia do transporte alternativo no munic��pio de Bel��m/PA

The study made in this thesis analyzes the new form of work organization at the urban collective transportation sector, so called Altemative Transportation which is a new form of public transportation that appears in the Brazilian urban context by the mid ninety' s, this work is made by independent or sub-contracted workers, usually organized in cooperatives . It reflects the investigation of new forms of precarious work, unformal which has been expanding in the urban transportation sector. Thus, discusses non regulation of the services sector problem the ways of survival of exc1uded workers from the formal work market mainly afier the capital productive restructure. It has as privileged area of investigation, the sector policy of urban transportation that make field of the main nets of political articulations that define the dynamic of the urban space. It is known that the urban collective transportation allows the access to the production, circulation and general consumption being necessary to the mobility of the resident population, mainly to those with low purchasing capacity. It becomes a field of empirical investigation at the Belem municipal, located at the Amazonic region - north Brazil. The main points dealed on this research start from concrete relations from the daily life of workers that deve1op their activity on the altemative transport mediated with theoretical references needed for understanding and interpretation of the studied reality. The investigation strategies were built from the abstract (theorical knowledge produced for the reality analyze) in concrete by the investigation quantitative-qualitative from this area of urban policy, making up possible the formation of a references chart to the analyses of the studied subject. Rescue his historicity, from characterization of the urban space of the metropolitan region of Belem passing true the forms of organization and urban services performances while essential production and reproduction element of the social relations. Identifies the main individuals that historically have been participating in the construction of the municipality transport policy and the ways of expression of the local political strength relations. Outstand the State paper on the net of established relations near the local power, as well as outstand the importance of social sciences in the understanding of urban policies in the transportation area, trying to bring input to the academicals -scientific debate .The above e1ected and mentioned points in this study are crucial for a critical reflection of the transportation policies. That relation is not given, but historically built at the power relation chart that makes up this unique area of the urban policies

A legitimidade da jurisdi����o de primeiro grau na concretiza����o dos direitos fundamentais: proposta de um novo modelo jur��dico-administrativo para o segundo grau de jurisdi����o

The current study is about the legitimacy of lower court jurisdiction as a way of exercising basic legal rights, proposing, therefore, a new legal-administrative model for appellate court. In order to achieve that, a demonstration of the importance of basic legal rights in the Brazilian legal system and an open interpretation in light of the Constitution, as a way to affirm said rights, among which are accessibility to the justice system and proper legal protection, is required. As a result, the legitimacy to access the legal system resides in the Constitution, where the interpreter should seek its basic principles to achieve basic legal rights. It is observed that the lack of credibility regarding lower court decisions comes from the dogmatic view of truth born from power, and therefore, that the truth resides in decisions from appellate court and not from lower court judges. A lower court judge holds a privileged position in providing basic legal rights for citizens, considering his close contact to the parties, the facts, and the evidences brought forth. Class action suit is presented as an important instrument able to lead the lower court judge to provide basic legal rights. Small Claims Courts may be used as paradigm to the creation of Appellate State Courts formed by lower court judges, reserving to higher jurisdiction courts and Federal Circuit Courts, the decisions of original competency and the management and institutional representation of the judiciary system. Instilling an internal democratization of the judiciary is also required, which means the participation of lower court judges in electing their peers to chief positions in the court system, as well as establishing a limited mandate to higher court judges.

A Constru����o social do conhecimento :a reorienta����o curricular via tema gerador na Escola Cabana em Bel��m/PA

Cette ��tude analyse l'exp��rience de r��orientation curriculaire atravers le sujet g��n��rateur, v��cue dans les ��coles qui composent le syst��me municipal d'��ducation de Bel��m du Par�� - ��cole Cabana, en ayant comme locus de recherche l'��cole Municipale Jo��o Carlos Batista. Ce mouvement de r��orientation curriculaire, qui rompt avec le mod��le traditionnel d'un curriculum lin��aire, hi��rarchique et fragment�� a comme pr��ssupos��es th��oriquesm��thodologiques les principes et les cat��gories freireanas la p��dagogie critique qui estime un curriculum interdisciplinaire, dialogique, d��mocratique et contextuel, �� partir de la syst��matisation d'une proposition theorico-m��thodologique de r��orientation curriculaire par le th��me g��n��rateur, c'est-��-dire, en partant de situations-probl��me de la communaut�� scolaire, en faisant des relations n��goci��es par les connaissances scolaires pour la compr��hension et possible intervention dans la r��alit��. Cette proposition est mise en oeuvre non seulement �� Bel��m, mais aussi par d autres municipalit��s du Br��sil. ��tant donn�� que l'��cole Cabana est une exp��rience inovatrice dans la tentative de viabiliser une ��ducation vraiment d��mocratique, elle dialogue encore avec autres exp��riences d'��coles de m��me nature au Br��sil, (comme l'��cole Plural-MG, l'��cole Citoyen - RS et l'��cole Candanga DF). �� partir des id��es de Paulo Freire, J. Sacrist��n, M. Apple, C. Linhares, A. Coulon et autres j apporte des r��flexions epistemologiques concernant le probl��me de la recherche qui consiste sur le registre et l'analyse de la tentative de construction sociale de la connaissance par le th��me g��n��rateur qui a eu lieu �� l'��cole Cabana dans la p��riode de 2001 �� 2004. Comme proc��dure m��thodologique, j'ai d��velopp�� une Recherche qualitative, de caract��re collaboratif, en utilisant comme techniques de rassemble de donn��es l observation participative dans le quotidien ��colier, des interviews semi-structur��es, et l'analyse des documents et des productions de l'��cole. Les r��sultats indiquent l'importance du registre de ce type d exp��rience, en soulignant leurs avances et reculs qui pourront servir de r��f��rentiel pour de futures politiques de r��orientation curriculaire dans la direction de la construction sociale de la connaissance et, par cons��quent, d'une ��ducation plus d��mocratique et tourn��e vers une citoyennet�� active
