This dissertation presents a reflection upon the notion of event, inspired by the contributions of Edgar Morin to the thinking of the present. The research analysis this notion particularly from the experience of the documentary titled Sangue do Barro, which was the winner of the 4th edition of DOCTV, in the federal state of Rio Grande do Norte in 2008. The study focuses on how facts from daily life can be approached by the documentary making process, and how in this process the questioning of facts leads to the questioning of social realities. In this perspective, through the illustrative case of Sangue do Barro, the research develops the hypothesis of how in the documentary process, which aims at revealing a particular history, is the revealing of the particular able to reflect the universal. The dissertation thus assumes this situation as precisely the configuration of the sociology of present, proposed by Edgar Morin. Furthermore, along with the theoretical premises of the sociology of the present, the research performs a brief historical analysis of documentary practices, Brazilian audiovisual public policies, and it also discusses the technical contributions of several contemporary film makers and contemporary thinkers, such as Jean Rouch, Bill Nichols, Ismail Xavier, Consuelo Lins, Gilles Lipovetsky, Jean Serroy, Michel Foucault, Alfredo Pena-Vega, Nicole Lapierre, etc

Cette tude propose de raliser une lecture du chourio, une confiture faite avec du sang, fabrique et consomme dans tout le Serid potiguar. Grace l observation ethnographique ralise entre 2003 et 2007, nous dcouvrons une conomie domestique, une organisation sociale, des formes de sociabilit et de solidarit contruites autour de l levage des porcs et des pratiques culinaires. Cette observation a aussi rvl un style alimentaire, des discours, des perceptions, des gots et des comportements relatifs la consommation de la confiture qui rsultent, em grande partie, de la relation dynamique entre une norme idalise et des pratiques observes qui ont montr des tensions et des contradictions entre ce qui est dit et ce qui est fait. Avec l tude du chourio, nous relisons une lecture de la culture alimentaire; notre intention a t de problmatiser l applicabilit des normes sociales et leur inscription dans la ralit. Ainsi, em faisant une analyse simbolique du chourio, nous considrons ensemble les aspects sociaux et symboliques et nous dcrivons comment les habitants du Serid pensent leur alimentation en corrlation avec les pratiques alimentaires et les formes de sociabilit. L tude a rvl que les prncipes de confiance et d interconnaissance, fonds sur les liens sociaux, structurent les relations constitues autour de l levage des porcs et de la production, de la distribution et de la consommation du chourio. D un point de vue symbolique, le sang est central dans le style alimentaire: il apparat comme une anti-nourriture et rvle des prohibitions et des transgressions. La contrastivit entre les pratiques et les discours est en relation directe avec la nature du chourio, fait avec le sang du porc et considr comme un dessert

Este estudo visou a determinar os valores eritroleucomtricos e quantificar as subpopulaes linfocitrias no sangue do cordo umbilical (SCU) e no sangue jugular de eqinos neonatos. Foi realizada a colheita de SCU e do sangue jugular de 20 potros ao nascimento. As amostras foram submetidas s determinaes dos valores eritroleucomtricos e quantificao de subpopulaes de linfcitos-T, pela tcnica citofluoromtrica. No foram verificadas diferenas significativas (P<0,05) entre os valores mdios de tais parmetros, entre o sangue jugular de neonatos e o SCU eqino. O valor total para neutrfilos segmentados, no SCU e na jugular dos neonatos, foi inferior ao reportado para eqinos ao nascimento. As contagens de linfcitos CD5+ e CD4+ no SCU e jugular de neonatos eqinos foram inferiores quelas admitidas para o sangue perifrico de eqinos adultos, indicando um componente imunolgico imaturo. No entanto, a contagem de linfcitos CD8+ foi semelhante descrita em sangue perifrico de eqinos adultos. A proporo CD4:CD8 obtida nesse ensaio, tanto para o SCU (2,64±0,91), como no sangue jugular de eqinos neonatos (2,41±0,81), demonstrou uma dominncia das clulas T CD4+ sobre os linfcitos T CD8+.

A importncia do estudo do sangue do cordo umbilical (SCU) tem sido verificada pela presena de clulas-tronco hematopoticas no SCU humano. O modelo experimental em co tem propiciado informaes importantes nos transplantes em humanos. Entretanto, apesar da importncia do SCU e do modelo experimental em ces, no existem estudos sobre a eletroforese de protenas sricas do cordo umbilical canino. No presente protocolo experimental, foi feita a colheita de SCU de 20 neonatos caninos, o qual foi utilizado para o fracionamento eletrofortico de suas protenas. Os valores mdios absolutos obtidos para protenas sricas totais, albumina, alfa, beta e gamaglobulinas no sangue do cordo umbilical de ces ao nascimento foram 3,09±0,59; 1,51±0,38; 0,87±0,17; 0,68±0,12 e 0,03±0,01, respectivamente. Todos os resultados apresentaram-se abaixo dos nveis reportados para animais adultos, devido passagem das protenas e suas fraes ocorrerem principalmente atravs do colostro e pela imaturidade heptica. em todos os traados eletroforticos do SCU de ces, foi observada uma pequena curva entre alfaglobulina 2 e betaglobulina 1, no relatada no soro de ces adultos. Portanto, neste experimento, foram observadas diferenas quantitativas no traado eletrofortico das protenas sricas do SCU de ces, ao nascimento, diferindo-os, neste particular, de ces em diferentes fases da vida ps-colostral.

O objetivo deste trabalho foi investigar o desenvolvimento de ascites em duas linhagens diferentes de frangos de corte, Hubbard e Pescoo-pelado, atravs da variao da viscosidade do sangue. As aves foram criadas at 45 dias de idade em duas temperaturas ambiente diferentes (termoneutra e fria) e com dieta de rao base de milho e farelo de soja, peletizada e de alta energia. Aos 28 e 45 dias de idade, amostras de 8 mL de sangue foram obtidas para determinao da viscosidade aparente em um viscosmetro de cilindros concntricos da marca Brookfield, modelo LVDII+ e para determinao do hematcrito. Aos 28 dias de idade foram verificadas algumas ocorrncias de ascite nas aves da linhagem Hubbard criadas temperatura ambiente fria, e aos 45 dias de idade, todos os frangos de corte dessa linhagem criados no ambiente frio apresentaram ascite. A linhagem Pescoo-pelado foi resistente ao desenvolvimento de ascite em todas as idades e temperaturas ambiente. A anlise dos resultados da viscosidade aparente do sangue indicaram que aves com valores similares ou maiores que 4 cP (centipoise) apresentaram ascite. Podemos concluir que na linhagem comercial o valor de 4 cP para a viscosidade aparente parece identificar o desenvolvimento de ascite.

The present work is grounded basically on the use of the Basic Tools for the Statistic Process Control SPC, with the intent to detect non-conformities on a given productive process. It consists on a case study accomplished at a Hemocenter in Natal (Rio Grande do Norte). In this study it is shown that, the Statistic Process Control Technique, which was used as a tool, is useful to identify on-conformities on the volume of hemocomponents. The gathering of the used data was performed by means of document analysis, direct observations and database queries. The results achieved from the study show that the analyzed products, even though when they have presented, in some cases, points out of control, they satisfied the ANVISA standards. Finally, suggestions for further improvement of the final product and guidance for future employment of CEP, also extended to other lines of production, are presented

This paper presents a study on coastal hydrodynamics and the spread of an oil spill in waters off Macau and Galinhos, on the east coast of the state of Rio Grande do Norte in Northeast Brazil. This area has a very marked coastal dynamic owing to the complexity of its geomorphological features, developed in a regime of semidiurnal mesotides involving reefs, spits, estuaries, mangroves, lakes and dunes. The region also plays an important role in the socioeconomic development of the state, given that the production of oil, natural gas, salt and shrimp is concentrated there. The series of oil platforms is interconnected by a pipeline system that carries oil to the local terminal. This pipeline could leak at any moment, causing immense ecological damage. To gauge the risks of an oil leak and resulting contamination of the coastal region, two hydrodynamic scenarios were simulated. The results obtained were used to implement a contaminant transport model with the creation of various oil leak scenarios modeled at different volumes (from small to large) and intensities (sporadic and continuous), at points considered critical for the model (on two platforms and at two pipeline intersections), under different wind (summer and winter) and tidal (high and low at new, full and quarter moon phases) conditions. The use of hydrodynamic circulation computer models as a tool for representing a real project design has been increasingly frequent in recent years, given that they enable the realistic simulation of the hydrodynamic circulation pattern in bodies of water and an analysis of the impacts caused by contaminants released into the water. This study used the computer models contained in SisBAHIA, in continuous development in the area of Coastal Engineering and Oceanography at COPPE/UFRJ

Digital Elevation Models (DEM) are numerical representations of a portion of the earth surface. Among several factors which affect the quality of a DEM, it should be emphasized the attention on the input data and the choice of the interpolating algorithm. On the other hand, several numerical models are used nowadays to characterize nearshore hydrodynamics and morphological changes in coastal areas, whose validation is based on field data collection. Independent on the complexity of the physical processes which are modeled, little attention has been given to the intrinsic bathymetric interpolation built within the numerical models of the specific application. Therefore, this study aims to investigate and to quantify the influence of the bathymetry, as obtained by a DEM, on the hydrodynamic circulation model at a coastal stretch, off the coast of the State of Rio Grande do Norte, Northeast Brazil. This coastal region is characterized by strong hydrodynamic and littoral processes, resulting in a very dynamic morphology with shallow coastal bathymetry. Important economic activities, such as oil exploitation and production, fisheries, salt ponds, shrimp farms and tourism, also bring impacts upon the local ecosystems and influence themselves the local hydrodynamics. This fact makes the region one of the most important for the development of the State, but also enhances the possibility of serious environmental accidents. As a hydrodynamic model, SisBaHiA - Environmental Hydrodynamics System ( Sistema Bsico de Hidrodinmica Ambiental ) was chosen, for it has been successfully employed at several locations along the Brazilian coast. This model was developed at the Coastal and Oceanographical Engineering Group of the Ocean Engineering Program at the Federal University of Rio de Janeiro. Several interpolating methods were tested for the construction of the DEM, namely Natural Neighbor, Kriging, Triangulation with Linear Interpolation, Inverse Distance to a Power, Nearest Neighbor, and Minimum Curvature, all implemented within the software Surfer. The bathymetry which was used as reference for the DEM was obtained from nautical charts provided by the Brazilian Hydrographic Service of the Brazilian Navy and from a field survey conducted in 2005. Changes in flow velocity and free surface elevation were evaluated under three aspects: a spatial vision along three profiles perpendicular to the coast and one profile longitudinal to the coast as shown; a temporal vision from three central nodes of the grid during 30 days; a hodograph analysis of components of speed in U and V, by different tidal cycles. Small, but negligible, variations in sea surface elevation were identified. However, the differences in flow and direction of velocities were significant, depending on the DEM

A agregao plaquetria avalia a funo das plaquetas atravs de diferentes vias de ativao plaquetria in vitro, fornecendo traados de ondas equivalentes propriedade fsica dessa agregao. Sabendo-se que a aspirina acetila irreversivelmente a enzima cicloxigenase prevenindo a gerao de tromboxana A2, potente ativador da agregao plaquetria, esta droga tem sido analisada h mais de trinta anos na clnica mdica em pacientes com doenas cardiovasculares como uma potente droga antitrombtica. Foram nossos objetivos obter traados de ondas correspondentes s fases da agregao plaquetria para nossa padronizao utilizando nosso grupo controle de doadores de sangue e compar-las com nosso grupo estudo, frente a diferentes agentes agonistas em diferentes concentraes: ADP 1M e 3M; AA, 0,5mM; ADR, 0,05 mg/mL, 0,025 mg/mL e 0,010 mg/mL. Os grupos analisados foram constitudos por 41 cardacos e 40 doadores de sangue considerados controle. Dos cardacos, 33 faziam uso regular do AAS na concentrao de 200 mg/dia e oito na concentrao de 100 mg/dia, sendo todos considerados hipertensos. A padronizao da agregometria estava na dependncia do encontro de traados correspondentes a ondas de agregao, sendo esses obtidos em porcentagem no tempo de cinco minutos estandartizados pelo aparelho utilizado. Comparando os resultados entre os pacientes e o grupo controle, foi possvel observar que, na presena dos agentes agregantes ADP 1M e ADP 3 M, ADR 0,05 mg/mL, 0,025mg/mL e 0,010 mg/mL, os pacientes apresentaram 1 onda, mas no 2 onda. Por sua vez, no caso do AA 0,5 mM no houve o encontro de traados de ondas.
