Métodos diagnósticos para detecção da Leucemia viral felina

The feline leukemia virus (FeLV) was described in 1964 by William Jarrett and collaborators wen find viral particles attached to the membrane of lymphoblasts in cat with lymphoma. The virus belongs to the family Retroviridae, subfamily oncornavirus. With worldwide distribution, the occurrence of FeLV has 1.6% in healthy cats and 10.8% in sick cats in Brazil. The mortality of persistently viremic animals in catteries is about 50% in two years and 80% in three years. In catteries that have endemic feline Coronavirus (FCoV), FeLV and / or Feline Immunodeficiency Virus (FIV), the FeLV infection has greater contribution to mortality. The test for infection and FeLV positive cats segregation is the main way to prevent the spread of infection. The diagnostic methods are based on clinical signs and changes compatible with FeLV infection observed by physical examination, complete blood count, X-ray, bone marrow aspirate and biochemical. The viral p27 protein is produced in infected cells in high amounts and is found in abundance in the cytoplasm and in body fluids enabling diagnosed methods such as enzyme-linked immunosorbent assay - ELISA and direct immunofluorescence, detection of viral genome (Chain Reaction Polymerase - PCR) and detection of the virus by virus isolation. Although diagnostic tests are highly sensitive, it should be made more than a confirmatory test, especially serological due to variable characteristic of the progress of infection

Educação popular sob influência nas manifestações populares

Esta monografia tem como objetivo apresentar uma pesquisa bibliográfica que investiga a educação popular como instrumento social usado por grupos étnicos formados ao longo da história nacional brasileira, que, devido ao contexto social em que foram submetidos indígenas e negros no período do Brasil Colônia reedificaram sua cultura descendente manifestando-a através da dança, do canto e expressões artísticas. A pesquisa reorganizou parcialmente o caminhar histórico dos afrodescendentes e influências indígenas focando alguns dos principais fatores histórico-sociais que estimularam a construção de manifestações populares, tais como: a Coroação do Maracatu e da Congada, a Roda de Jongo, o Samba de Coco, o Lundu e Tambú (Batuque de Umbigada). Para auxiliar o entendimento deste processo foi elaborada uma abordagem qualitativa, aprofundando conhecimentos sobre a educação e manifestações populares brasileiras usando como metodologia a coleta de dados bibliográficos, análise e extração de dados de documentários referentes às manifestações populares no Brasil, consultam a sites oficiais, e também depoimentos recolhidos com membros da comunidade negra das cidades de Rio Claro e Campinas/ SP. O resultado foi uma monografia composta por elementos históricos que demonstram as contribuições da educação popular na recolocação social dos descendentes de ex escravos no cenário cultural do Brasil

Fractografia quantitativa: correlação entre dimensão fractal e tenacidade à fratura em compósitos fibra de carbono/epóxi

The fracture surfaces express the sequence of events of energy release due to crack propagation by linking the relief of the fracture to the loading stresses. This study aims to evaluate the heterogeneity of the critical zone for the advancement of the crack along its entire length in a thermoset composite carbon fiber and epoxy matrix, fractured in DCB testing (Double Cantilever Beam) and ENF (End-Notched Flexure). Investigations were made from image stacks obtained by optical reflection of extended depth from focus reconstruction. The program NIH Image J was used to obtain elevation map and fully focused images of the fracture surface, whose topographies were quantitatively analyzed. The monofractal behavior for DCB samples was assessed as being heterogeneous along the crack front and along the crack for all the conditionings. For the samples fractured in ENF test, there was a strong positive correlation to the natural condition, considering the fibers at 0° for the monofractal dimension and structural dimension (Df and Ds). For fibers at 90° to crack propagation, there was a moderate positive correlation for the textural dimension of natural condition. However, for the samples under ultraviolet condition and those subjected to thermal cycles, there was no correlation between the fractal dimension and fracture toughness in mode II

Modelo tectono-estrutural dos campos de petróleo Namorado, Cherne e Albacora

The main goal in this research is a tectono-estructural characterization of the Cherne, Albacora and Namorado Fields, located at Campos Basin, in order to investigate the relationship between the geologic evolution and the rock´s physical properties of the reservoir, and how they affect the hydrocarbon accumulation in those fields. Well correlations show that the inferior turbidites have a regional lateral continuity. Basic petrophysics analysis, calculated here, shows that the three fields present porosity values that range from 15 to 20%, shale volume range from 26 to 30% and formation water saturation range from 23 to 45%, based on formation water resistivity dada from Albacora Field. Petrophysics maps feature a trend in Albacora Field that increase the porosity values to SE, and in Cherne and Namorado Field the trend increase towards N. Seismic horizons where interpreted between the first appearance of the Namorado Sandstone and the top of Quissamã Formation. This interval presents normal listric faulting, in Cherne and Namorado Field with NWSE and NE-SW direction, and sedimentation trend to NW-SE, in Albacora Field the faulting presents a NNE-SSW and N-S direction, with a sedimentation trend to NE-SW. Seismic attribute maps present amplitude anomalies close to the producing wells, and on Namorado Field, it indicates a potential hydrocarbon accumulation in the NE region. For each field is indicated laboratory tests for a better characterization of the petrophysical properties, since that they don’t form the same reservoir level, therefore, not influencing the water saturation calculation

Células granulares do giro denteado recém-geradas em ratos epilépticos jovens e idosos apresentam dendritos basais

As células granulares do giro denteado do hipocampo são continuamente geradas na zona subgranular em mamíferos. Condições como epilepsia e envelhecimento podem alterar a proliferação celular e também certas características morfológicas das células granulares, como a formação de dendritos basais. Através da imunohistoquímica para doublecortin, marcador neuronal de células granulares imaturas, o estudo visa avaliar a proliferação destas células e quantificar o número de dendritos basais em animais epilépticos crônicos usando o modelo de Epilepsia de Lobo Temporal induzido por pilocarpina. Contatamos que a relação de células granulares com dendritos basais permanece constante no decorrer da vida do animal epiléptico de forma que esta alteração plástica das células granulares não seja fator determinante na patologia

O retorno: identidades à deriva no romance português contemporâneo

This paper concentrates on the analysis of how the typical voices of History are manifested, which is achieved by the aesthetics of the contemporary Portuguese narrative, as it aims at the same time the reflexion and the reformulation of the Lusitanian cultural imaginary in the course of O retorno, a novel by Dulce Maria Cardoso. The hypothesis that arises is that the trajectory of Rui’s individual experience, as wells as the other’s characters “retornados” looking for identity, is parallel to the proposed revision of the Portuguese nation collective cultural imaginary in the decolonization context, after the 25th April Revolution. It is its objective to investigate how the historical processes concerned to the concepts of exile and uprooting, displacement and belonging (BAUMAN, 2005) are fictionalized in the novel, seen as motes for Rui’s pursuit for identity and for the revision of the Portuguese Destiny theme

Circulação atmosférica e precipitação pluviométrica na Bacia do Itajaí - SC: um estudo climatológico aplicado

The work is guided by the detailing of the Itajaí river basin, SC, rainfall dynamics at the annual, seasonal and monthly levels, allowing us to identify different responses that each location gives to the regional atmospheric circulation, particularly the rainfall. In this sense, we are aiming at approaching the concept of rhythm, which must be obtained at the daily level. The analysis at different climate scales was possible through isohyetal maps, trend lines, and Schroeder pluviographs. Moreover, we established the flow rate of the air masses by means of the Venn diagram. This data made it possible to assess the behavior of rains on that site and the reason why it is the stage of major flooding, as occurred in November 2008. The relatively mountainous topography combined with the frequent invasions of the Atlantic Polar Front, which often stop over the region, generate events of that magnitude, with high volumes accumulated in short periods of time. Such extreme events reinforce the idea of the search for the succession of types of weather to the detriment of averages that tend to abstract the reality

O uso do geoprocessamento para mapear as áreas verdes urbanas como indicador de qualidade ambiental no município de Americana/SP

The style of life in the cities deprives the man of the contact with nature. As a way to escape from the turbulent reality of the urban system, the urban planning provides areas that allow the contact between man and nature like botanical gardens, parks, leafy squares, etc. These places, through specific analysis, are also called green areas. Thus, the main purpose of this research is to outline and analyze, through geoprocessing techniques, green areas of Americana, São Paulo considering them as indicators of urban environmental quality. This evaluation will be based on the methodology adapted by Bargos (2010) where products of remote sensing were used (aerial photos and satellite images) and it will be also based on field work and calculation of the amount of green areas. The software ESRI ArcGIS® will be used to create thematic maps connected with city’s green areas. Based on the results achieved in this study, it’s expected to contribute to the government of the city of Americana in order to provide benefits of analysis for decision makers in the context of urban planning aiming an improvement in the urban environmental quality, thus benefiting its entire population

Barreiras à entrada no Setor Siderúrgico Brasileiro no período de 1993 a 2012

This study aims to identify and analyze the barriers to entry in the two technological routes (integrated and semi - integrated mills) , the Brazilian steel industry , specifically in the areas of Plans and Long , in the period 1993-2012 . Thus, the study is characterized as an exploratory - descriptive research, based on data collection from secondary sources. The competitiveness is influenced by structural market factor, among them the threat of new market entrants. The entrants can have their ticket inhibited by entry barriers. In the steel industry, it was identified that the main strong structural barriers are economic, the type of scale economy, highlighting the idle capacity, and sunk costs. Institutional and economic barriers, the diversification and product differentiation type, are considered moderate barriers. Economic barriers, the type absolute cost advantage and initial capital requirements, and strategic price barrier are considered weak. With this, one can consider that the input type which most closely approximates the market for national steel industries is blocked, since their main barriers are the structural type

O eterno feminino: arquétipos literários em Mujeres de Eduardo Galeano

Le champ littéraire est plein d’oeuvres qui remettent à des mythes. L’ensemble de récits Mujeres, de Eduardo Galeano, a comme thématique la femme et il est composé par des micro-contes, genre narratif qui promeut une condensation maximale d’eléments thématiques et structuraux. Il s’agit des descriptions littéraires où la synthèse est placée ou même niveau que le lyrisme. Ayant pour objectif d’analiser la nature archétypique des mythes sur la féminité, nous avons travaillé spécifiquement les contes de Mujeres où se reconstruisent poétiquement des mythes de la féminité. Méthodologiquement, notre notre étude a pour base la mythocritique et la théorie des structures anthropologiques de l’imaginaire ídéalisées par Gilbert Durand. En partant de ces bases, nous avons réalisé l’analyse des récits qui s’articulent en notre corpus, ayant pour but, celui d’identifier les divers artifices narratifs spécifiques qui y opèrent. Par le moyen des mythèmes présents dans les récits, nous avons révélé les structures archétypiques du texte et nous avons constaté comment elles s’édifient littérairement. En outre, nous avons élucidé la teneur de la représentativité archétypique de la feminité inhérente aux récits et finalement, nous avons rassemblé les situations et les combinatoires qui existent dans l’ensemble de microrécits, traçant les connexions possibles qui y existent. Ainsi, nous avons fait une étude proprement dite, d´analyse mythocritique

Desenvolvimento de uma nova sistemática para centragem e alinhamento da plataforma giratória R-9350 na mandriladora CNC PAMA SPEEDRAM 3000

In heavy machining industries, a critical point that must be taken into account is setup. Because the characteristics of machine tools and parts to be machined, usually pieces robust and large, the preparation of these parts must be made accurately for machining has a good result as planned. As a result of the difficulty raised in the setup machining of heavy parts, companies in this segment seek alternatives to reduce the unproductive time caused by setup and optimize machining processes. One way was found that these companies create operating instructions that describe and standardize the operation between its employees, as well as deploy a control machining times to measure the unproductive time caused by the setup. This work studied a new system for the realization of centering and alignment of Rotating Deck R-9350 in CNC Milling Machine PAMA Speedram 3000, in Liebherr Brazil company. The part Rotating Deck R-9350 is a critical part in which its machining in PAMA Milling Machine is made in three phases and their setup times are quite high and involve stopping the machine. It has been tested and proposed a solution to the realization of this part of the setup without the use of the machine, but of the measuring instrument three-dimensional Laser tracker, with which the machine continued to work, while he was in the centering and alignment of other parts. It was noted that the instrument technically attended the need and it was possible to perform this operation more accurately

Determinação experimental da tenacidade à fratura em baixas temperaturas de tubos de aço API 5L X70

Because of the great metallurgical advances, the welded tubes by HF / ERW (High Frequency / Electrical Resistance Welding) have played a more active role in the oil and gas, gradually replacing tubes produced by other processes (UOE, SAW, and others) to deep water applications, in high and extremely low temperatures, highpressure conditions and in highly corrosive environments. However, studies have revealed that defects in the welded joints are in one of main causes of failures in pipelines. Associated with damage external and the stringent requirements of this sector, the welded joints become particularly critical for his toughness and the determination of this particular property is fundamental. This study aims to evaluate the toughness of the HF / ERW pipes in HSLA steel API X70 class, used in pipelines transport systems of gas and oil from data obtained with CTOD tests (Crack Tip Opening Displacement). The main objectives of this project are: mechanical and microstructural characterization of steels API X70 manufactured in Brazil; and evaluation of the toughness of weld process by HF / ERW steel API X70 national. After having the tests done, mechanical, chemical and metallurgical, we have the conclusion that those pipe are in agreement to API 5L 42ª edition for X70MO and the toughness behaves like the expected
