Criopreservação de sêmen de epidídimo de garanhões

It is a fact that Brasil has a featured position in the equine market due to the size and the high quality of its squad. To keep the competitivity, the reproduction biotechnologies have a big and important role. The cryopreservation of stallion semen, for example, generates innumerous advantages, which includes: larger number of obtained doses, storing genetic material for undetermined time, using the semen of a good stallion even after its dead or any other event that makes both semen collection and mating impossible, etc. In this context, the cryopreservation of epididymal sperm, has been seen as a promising technique in equine reproduction. The epididymal cauda has a significant quantity of fertile spermatozoa and this ensures a huge store of cells in cases of unexpected accidents, which can early interrupt with the reproductive life of a stallion. Lots of studies are being developed using the cryopreservation of stallion epididymal sperm. These studies permit the propagation of high quality genetic material and make possible for the stallion owner to opt for a final semen collect in unexpected circumstances

Crise da cafeicultura e seus efeitos socioeconômicos no município de Dracena (SP)

The coffee crisis in the 1980s reached deeply municipality of Dracena, considering that the coffee had significant social and economic importance to the area. In this context, the research aimed to analyze the socioeconomic consequences that this crisis has provided small rural proprietors of the county. To achieve this goal we seek to articulate the theoretical reference, with data from secondary sources, interviews with the main responsible for the agricultural sector and an application questionnaire to 21 small rural proprietors of the county. It was found that, due to the dependence relationship with the coffee, the economy of the city suffered from the attack of said culture during the 1980s. Rural producers who cultivated such crops as the main, had to readjust productively to remain in the countryside, but the economic and social development that coffee was brought in earlier times was not rescued. As a consequence, there has been an intensification of evasion demographic of rural municipality, a process that had begun in the 1970s and was strongly reinforced by the crisis of the coffee culture. We note that from the 2000s, the situation became better for small rural proprietors in order that public policies implemented now serve, in part, the needs of those with greater efficiency. This situation can be evidenced by a slight reduction in the number of rural people dracenense. Despite improvements recorded since the 2000s, the situation is still not ideal, given that many small proprietors surveyed expressed dissatisfaction. In this context, we note that the performance and joint of federal, state and municipal government are essential so that public policies are efficient, thus providing decent conditions for social reproduction of small rural proprietors and their dependents in the countryside

Zoneamento geoambiental do município e região de Franca-SP

O município de Franca-SP situa-se na Província Geomorfológica das Cuestas Basálticas no nordeste paulista, a qual possui características ambientais próprias. De uma forma geral, a região de Franca enfrenta problemas ambientais como a suscetibilidade à erosão linear e laminar, aos movimentos de massa e ao assoreamento dos canais de drenagem. Estes problemas, por sua vez, induzem a situações socioeconômicas, como o incremento da pobreza, aglomeração urbana e, uma emergente demanda da sociedade por mudanças no âmbito da gestão local. Assim, devem ser efetuados estudos detalhados sobre o meio, a fim de minimizar e/ou evitar tais problemas. Desta forma, propos-se a realização do Zoneamento Geoambiental, o que implica no levantamento, análise, interpretação e correlação dos diferentes componentes ambientais, visando dar subsídio a órgãos públicos e proprietários rurais, tanto na fase de planejamento como na implantação de culturas agrícolas, pecuária, reflorestamento e uso da água superficial (lençol freático), de maneira racional e ambientalmente sustentável, garantindo assim a ocupação adequada do solo e a melhor conservação dos recursos naturais. O trabalho iniciou-se com a organização e reinterpretação dos dados pré-existentes (topográficos, geológicos, pedológicos, geomorfológicos, morfoestruturais, de coberturas de alteração intempérica e sócio-econômicos) e geração e/ou reorganização de novos dados e propostas para a minimização dos impactos sócio-ambientais (rede de drenagem, hipsométricos, morfométricos, tectônicos, geológicos, geomorfológicos, climáticos e bióticos) com a utilização de técnicas de fotointerpretação de diversos sensores remotos e de campo. Deste modo, a correlação de todas as informações geoambientais relativas ao município proporcionou a delimitação das suas zonas e subzonas geoambientais...

Síndrome dilatação-vólvulo gástrico em cães

The gastric dilatation- volvulus (GDV) is an acute and potentially lethal disease, characterized by increased size of the stomach associated with mesenteric rotation on its axis, which affects mainly large breed dogs and giants with deep and narrow chest. The diagnosis is made from the history, physical examination, clinical signs and radiographic evaluation. It is an emergency that requires immediate therapy and consists on protocols to treat shock, gastric decompression, surgical repositioning of the stomach, gastropexy and intensive post-operative care. Despite the significant progress in the elucidation of pathophysiological events, risk factors and treatment, there was almost no progress in determining the root causes of this disease. A significant advance was recently described in the literature on this topic is the technique of gastropexy laparoscopy. Instruct the owners of the high risk breeds is extremely important to avoid situations in which the severity of the illness make the surgical treatment impracticable and the animal’s condition irreversible

Gestão ambiental na produção avícola: estudo de caso

The present study addresses the application of the Environmental Management System in chicken production on a farm owned by the Nardo brothers, located in the city of Guapiaçu/SP (Brazil). The objectives were to analyze the process of solid waste generation, destination and forms of treatment in this activity; propose measures to reduce the use of potable water for non-potable ends; determine other measures identified through a questionnaire drafted by Embrapa (Brazilian Agriculture Research Cooperative) and administered to employees who have direct involvement in the productive process; pay visits to chicken production enterprises; and employ the guidelines proposed by the National Fowl-Breeding Sanitation Program that guide the application of the Environmental Management System. Adequate management of waste was put into effect through the construction of a compost shed capable of meeting current production demands, in which all procedures were accompanied – from civil construction to the commercialization process of the organic fertilizer generated. The rain-gathering system for the roofs of the pens proposed to reduce the consumption of potable ground water destined for washing the floors of the pens was completely dimensioned and budgeted, allowing the motivated owners to place the project into effect in a timely fashion. Other simpler but no less important proposals were also made in order to bring the production up to the required quality standards.

Atividades de aventura na natureza como negócio no contexto do lazer

As atividades de aventura na natureza surgem com objetivo de atender aos interesses pelo ar puro, pela ginástica na natureza de uma sociedade influenciada pelo modelo higienista. Esportes na natureza de caráter aventureiro começam então a ser praticados especialmente em países ‘desenvolvidos’. Fatores motivacionais, a necessidade de fuga do cotidiano, a busca por novas sensações e o avanço tecnológico possibilitou a melhoria na qualidade de equipamentos utilizados para segurança e contribuíram para a ampliação do mercado das atividades de aventura na natureza. Além disso, a grande quantidade de locais naturais como praias, montanhas, chapadas, matas, cerrados, cavernas, permite que este mercado, de caráter turístico, se expanda pelo Brasil.

Os dados foram analisados descritivamente, por meio da Técnica de Análise de Conteúdo Temático, ampliando assim, as reflexões na área

Avaliação dos danos por fluência da serpentina da caldeira da REVAP

The determination of the remaining life of equipment operating at high temperatures has been a great challenge for their owners. The use of safety factors, often conservative, makes the replacement of equipment or of its components at the end of the life of design gets financially unviable. This study aimed to estimate the remaining life of the serpentine of the secondary superheater of one of REVAP’s boilers (Henrique Lage Refinery), through accelerated creep tests and comparison of the results with the techniques based on microstructure and hardness. When conducting a proper assessment it’s possible to increase the equipment reliability, ensuring operational continuity and physical integrity. The tests showed a minimal residual life of 12.7 years (111,252 hours), longer than the design life (100,000 hours), even after a period of operation of approximately 250,000 hours, confirming the conservatism of the project. The techniques based on microstructure and hardness did not show good correlation with the creep test, decreasing the reliability of these techniques in determining the residual life

Insuficiência renal crônica em cães

The kidneys, for his anatomical and functional characteristics, are sensitive to affections that take the liberation of renal toxins or the blood supply, causing irreversible injuries to his renoparenchymal tissue that is substituted by fibrous tissue. Even after the resolution of the basic cause, there will be the loss of a significant number of his functional unity, renal adaptations will take place in the attempt of maintaining the renal function. These adaptations produce additional injuries, perpetuating to loss of renoparenchymal tissue and the reduction of the renal function. The renal insufficiency (IR) takes place after the loss of 3/4 of the number of his functional unities. Before the progression to the phase of IR, the animal shows up practically without symptoms, but for the gradual increase of the urinary and of the ingestion of water. The reduction of the degree of renal function leads to alterations system compensatory for the accumulation of substances that would suffer renal excretion. The progression of IR leads to the phase of the syndrome urêmica. In this phase the animal presents innumerable clinical signs that can take it to the death. The treatment is symptomatic and dietetic, but depending on the phase not much efficient. Because of being progressive and insidious, the IRC demands the preparation of campaigns and programs of explanation for the veterinary doctors who aim for the consciousness and/or sensibility of the owners to carry out periodic examinations of selection that precociously detect the renal dysfunction. The diagnosis in the beginning IR enables the efficiency of the treatment in stop or slowing his progression, extending the time and quality of life of the patient

Significados da reforma agrária em bairros periféricos de Presidente Prudente (SP): uma tentativa de diálogo entre a luta pela Terra e a soberania alimentar

La lucha por la tierra en el Brasil se confunde con la própria historia del país, erigida sobre una cuestión agraria turbulenta en la cual ha predominado la hegemonía de los grandes proprietarios de tierra, tanto en la forma de latifundistas, cuanto, más recientemente, de los empresarios del agribusiness, caracterizando una versión más moderna de la dominación de la lógica del capital en detrimento de las demás formas de organización de la vida. A partir de la segunda mitad del siglo XX, ocurre un aguzamiento de los conflictos por la tierra con la emergencia de los principales movimientos sociales en Brasil, como el MST. Esos movimientos surgen en un contexto de transformación de la formación socioespacial brasileña, marcada por la creciente urbanización del país, lo que repercute em las sus formas de organización, pasando a comparecer una preocupación con la población urbana en las discusiones y acciones en pro de la Reforma Agraria. Yuxtaponiendo-se a eso proceso, también ha emergido fortemiente en las últimas décadas la problemática de la hambre en el mundo, tanto a través de los dados alarmantes de los organismos supranacionales (FAO), como del debate impulsado por los movimientos sociales acerca de la Soberanía Alimentaria (Via Campesina). Todos esos elementos merecen atención em esto trabajo, que busca aprehender cómo se efectiva la participación de barrios de la periferia pobre de la ciudad de Presidente Prudente/SP en el proceso de lucha por la tierra en el Pontal del Paranapanema, haciendo eso por lo medio de una lectura geográfica de esa realidad que prime por la superación analítica de la disociación entre ciudad y campo, como se fueran espacios inertes entre sí. Además, es nuestro objetivo destacar las motivaciones que llevan los sujetos protagonistas de eso proceso a dejaren la ciudad y adhieriren a la lucha por la tierra, permitiendo identificar elementos que extrapolan la esfera económico-material

A reprodução capitalista no setor habitacional e as transformações no espaço urbano: o caso do Jardim Letícia (Leme-SP)

This paper discusses urban space focusing on the housing sector, the capitalist reproduction and some changes occurring in that space as a result of the dynamics of the real estate sector and interests of financial agents, developers and urban land owners/speculators. The changes imposed to cities value abstract spaces over concrete ones, showing the unbalance between the interests of agents, who have in view the market, and those of dwellers, who live daily in such areas. Based on these reflections, a case study was carried out in the Jardim Letícia neighborhood in Leme city (state of São Paulo) in order to understand the space production and reproduction in that area, analyze some of the main problems faced by local people, and identify some agents involved in the process.

A região de Araraquara e a constituição do local: experiência em desenvolvimento rural a partir do SAI - Sistema Agroindustrial Integrado

The research aims to map and understand the SAI- Integrated Agroindustrial System of SEBRAE, topic program directed to small and medium "rural entrepreneurs". The SAI policy seeks targeted result saiming to qualify productive agents (smallholders) to a "mark et under construction". In the study I high light the "production location", as a constituent en vironment with own productive and defining characteristics of this location and of the productive agent. I aim to perceive the location (region of Araraquara) as a topic en vironment of a type of "alternative "agriculture, that in principle is “parallel” to the large hegemonic model of the economies of scale, of monoculture and concentrative, which in the region is taken as that of the "sugarcane industry". I understand the coexistence of these different models as central to understand the development of capitalism, which I treat as "cognitive capitalism".
