Estudo da fluidodinâmica de uma mistura de sólidos em um leito fluidizado gás-sólido

Fluidization consists in a bed of solid particles acquire fluid behavior by using a fluid (in this case air) flowing through the solid particles. Because of this, it can be a good mix of these materials, as well as to show increased rates of heat and mass transport. The fluid flowing through the spaces between the particles gives an interstitial velocity, that if is too low does not cause movement of the particulates. The gradual increase in speed will generate small vibrations between the particles promotes its fluidization. Our study focus in the fluid state of solid bed , when the fluid velocity reaches a state where the drag forces are sufficient to support the weight of the solid particles making these solids behave like fluids . Knowledge of the minimum velocity required to fluidize that particles is of great importance since below this speed there is no fluidization, and far above it, the solids are carried out of the bed. The fluidized bed reactor is widely used in physics and engineering, particularly in gas-solid fluidization, with emphasis on thermochemical processes

Aspectos petrográficos dos carbonatos da Formação Riachuelo - Albiano, bacia de Sergipe

The carbonatic rocks have great importance in petroleum geology, since most hydrocarbons reservoirs in the world are associated to this kind of rock. The new giant petroleum fields discovered in the Brazilian southeast Atlantic margin are directly connected to calcareous rocks, which are subjacent to the Aptian evaporite pack. This demand an increase in the number of geologists able to study such deposits. The Aptian carbonatic platform is completely exposed only in the Sergipe-Alagoas Basin. Therefore, it works as a natural laboratory to the study and understanding of this kind of rock. The Sergipe Basin is situated in the east Brazilian coast, and has its evolutional history is intimately related to the formation of the South Atlantic Ocean, through the break-up of the Gondwana supercontinent. The marine sequence of the Brazilian marginal basins is of Albian age and is marked by the development of carbonatic platforms. In doing so, this paper aims to analyze the Albian limestones from Riachuelo Formation of the Sergipe Basin. The project gave to the student the opportunity to increase his knowledge in carbonates, due to the laboratory and outdoor activities. The studied deposits, within a regional outline, were petrografically described, allowing interpretations about the evolution of the former South Atlantic Ocean. Ten points were visited where samples were collected for making of thin sheets. In this work several carbonatic facies were identified totaling 116 laminates described.

Análise da evolução das linhas suburbanas no transporte coletivo intermunicipal do estado de São Paulo

This study aims to analyze the intermunicipal collective transportation in The State of São Paulo, according to the relation of lines per permittee company of June/2002 and June/2012. We worked on the suburban and road bus lines. After analyzing the data, we seek to know how was the evolution of these lines in the State of São Paulo, the regions in which these lines were more developed and the groups that monopolize increasingly the intermunicipal collective transportation. It was made a list of some variables that enabled a comparison with the road system and we also showed the considerable increase of the suburban lines, which became more common as time goes by to compete against the clandestine transportation

Estudo geofísico em um depósito de manganês supergênico no município de Itapira - SP

The mining research is a complex activity, which should preferably involve the combination of direct and indirect techniques of geological research. The increasing demand for base metals in domestic and international markets provide the revaluation of mineral occurrences, which can be converted into deposits and mines. This paper presents the results of the application of geophysical methods of electric resistivity and induced polarization in main foliation parallel to the arrangement of the area, in a deposit of oxides and hydroxides in massive and disseminated ores, docked in gneisses and quartzites, located in the municipality of Itapira, in the North of the State of São Paulo in Brazil. Inversion models indicate the predominance of high cargabilidade that partially coincide with low resistivity values. Integration of geophysical data made possible the drafting of sections of electric walking with cross-checking distance x depth, for detailing your target. The integrated analysis of geophysical and geological structural data leads to the conclusion that the primary mining suffers structural control with the regional foliation in ores

Biotecnologias aplicadas à reprodução de éguas velhas

The acceptance of biotechnology for the most equine breeders association had a significant effect in the horse industry, gaining popularity around the world, because the increasing on the genetic gain, allowing the use of sub fertile mares and stallions with high genetics value on reproduction. The embryos in vitro production of human and cattle has been used with success, however in vitro embryo production is not efficient in the horse, as oocyte transfer (OT) and intracytoplasmatic sperm injection (ICSI). The oocyte transfer has been used especially in subfertile old mares presenting reproductive pathologies as: endometrite, cervical and uterine adhesions, blocked oviduct, perineal laceration and ovulation failures. During oocyte recovery process, the oocytes must be collected from immature follicles that need be matured in vitro or in vivo matured oocytes from pre-ovulatory follicles through the transvaginal aspiration guided by ultrasound. The recovered oocyte is transferred to a previously inseminated recipient mare, through the flank laparotomy. The intracytoplasmatic sperm injection (ICSI) is a procedure of in vitro fertilization that needs only one sperm that is aspirated and injected inside the oocyte. The oocytes used, can be from mature and immature follicles. Fresh, cooled and frozen semen can be used, because the procedure not requires a functional sperm. The use of Piezo drill resulted in a breakthrough the pellucid zone, allowing the vibration per minute provided in the sperm injection pipette, a major result of cleaved oocytes, due to a better sperm injection in the oocyte. The embryo transfer can be straight inside the oviduct, as also transcervical transferred after embryo culture produced in vitro. In conclusion both procedures (OT and ICSI) are effective to be used on equine assisted reproduction, getting results even lower than expected, but satisfactory from animal genetically superior

Desenvolvimento humano: a realidade além dos números

The book-report Human Development: the reality beyond the numbers addresses issues related to the Development Index (IDH), of Brazil, in a general context, and the city of Bauru, in the local context. The “IDH” is a number that serves as a comparison between countries, in order to measure the degree of economic development and the quality of life offered to the population. The classification, if high, can be readily used as a means of aggrandizement national and if low, can be used to highlight the weaknesses national. Understanding the role of media as an agent capable of promoting social debates of great importance, this book-report aims to discuss the concept of human development beyond the numbers commonly reported, prompting debates on the issue of human development: whether in relation to social issues, public policy or the role of the media in the process of contributing to the formation of public opinion. The methodology used was the data collection and the research literature, besides journalistic techniques, such as interview, report and profile

Estudo dos mixozoários (Myxozoa : Myxosporea) parasitos dos peixes characiformes Acestrorhynchus lacustris (Lütken, 1875) e Steindachnerina insculpta (Fernández-Yépez, 1948) coletados no Rio do Peixe, médio Rio Tietê, SP, Brasil

The São Paulo State has as one of its main rivers the Tietê, which is an extremely important source because of its biodiversity, use in navigation and mainly as direct supplier of water for thousands of people in the region. Currently, the biodiversity of marine and freshwater ecosystems has been threatened, primarily by environmental problems resulting from the degradation of ecosystems, an example is the stretch of the Middle Tietê River, where the Barra Bonita dam (SP) focused virtually the whole load organic effluents from the metropolitan region of São Paulo, leading to eutrophication with the loss of water quality. This basin is located in the Peixe’s River, a tributary of the Barra Bonita whose sources are on the slopes of the Cuesta de Botucatu, presenting an altitudinal gradient in a good state of conservation and water quality. From another perspective, the studies related to parasites and other pathogens of aquatic organisms have considerably increased the relevance, especially those hosts with potential for growing and marketing, given the significant increase these activities in Brazil and worldwide. Among the agents responsible for diseases in fish are the myxosporean, which can cause major economic damage, with high mortality ratios. Based on the above, this study evaluated the biodiversity of myxosporean parasites of two species of fish Acestrorhynchus lacustris and Steindachnerina insculpta. During the period January to November 2012, 40 specimens of Acestrorhynchus lacustris and 33 specimens of Steindachnerina insculpta were collected from the Peoxe’s river at four different points. The necropsies were performed and all organs were analyzed looking for myxosporean. Only the species Steindachnerina insculpta had their gills parasitized by two species of the genus Henneguya

Expressão da ciclooxigenase – 2 (COX-2) em carcinomas mamários espontâneos em cadelas

The immunohistochemistry regarding the expression of cyclooxygenase-2 (COX-2) for the woman’s breast cancer became a routine application due to the biological relevance. It is possible that COX-2 is closely related to tumor angiogenesis, inhibition of apoptosis mechanism, adhesion and metastasis. Herewith the COX-2 expression contributes to verify the malignant potential of the breast cancer. However it is slightly used in female dog’s spontaneous breast carcinomas. Keeping this in mind, the \cox-2 inhibitions appear as a promising perspective for the prevention and treatment of some sorts of cancer. The present dissertation had as main purpose to show the occurrence of the COX-2 expression in some of the female dog’s spontaneous breast carcinomas

Diagnóstico da gestão e do gerenciamento dos resíduos eletroeletrônicos gerados no campus da Faculdade de Engenharia de Guaratinguetá/Unesp

Currently, in Brazil, the quantity and quality of new types of wastes, discarded without criteria in urban areas, has been responsible for considerable impacts on public health and the environment. According to a report prepared by the Institute of Applied Economic Research (IPEA), the country loses about U.S. $ 8 billion annually, due lack of waste recycling, which go directly into landfills or dumps. Among these solid wastes are waste electrical and electronic equipment (WEEE), whose characteristics are complex, by having in its composition substances of high value-added and other health hazards which require different treatment of household waste. Aiming to fill the gap in Brazilian environmental legislation, on 02/08/2010, was sanctioned the National Policy Solid Waste (Law No. 12,305), already regulated on 23/12/2010 (Decree No 7404), whose based on the following principles:reduction of waste generation and toxicity of shared responsibility, proper planning management, social inclusion of waste pickers and sustainable production and consumption. Given the above, this work presented here, aims generally present a diagnosis of the current situation of electronic waste generated in the Faculty of Engineering, Campus Guaratinguetá, FEG / UNESP, to provide data for management and management of these waste, based on sustainability, the economic losses and minimizing environmental impacts and public health related to the flow and the improper disposal of these wastes

Dinâmica da produção de serapilheira em diferentes sistemas de restauração florestal

The ecological restoration is an alternative to increasingly important for biodiversity conservation. However, actions need indicators to evaluate its effectiveness in restablishment ecological processes, including nutrient cycling. The objective of this study was to compare the annual litterfall from five different treatments for forest restoration, compared with a neighboring fragment of Seasonal Semideciduous Forest, in order to subsidize their management plans for ecological restoration. Litter traps of 0.25m² were used, and a total production was: 1700.6 Kg. ha-1.year-1(treatment 1), 7748.1 Kg. ha-1.year-1(treatment 2), 7120.8 Kg. ha-1.year-1 (treatment 3), 9254.5 Kg. ha- 1.year-1 (treatment 4), 7130.2 Kg. ha-1.year-1 (treatment 5) and 8876 Kg. ha-1.year-1 (fragment of Seasonal Semideciduous Forest - treatment 6). The leaf fraction was the largest contributor to the deposition of litter in all treatments. Litter served as a good environmental indicator that can be used as a tool to support management plans. Key words: Litterfall, forest restoration and Seasonal Semideciduous Forest

The issue of sustainability was explained in order to serve as a tool to expand the options available to upgrade a building in front of their impact on the environment

A ironia na peça O rei da velha, de Oswald de Andrade

Este trabalho tem como objetivo traçar um panorama artístico literário presente na produção do escritor modernista Oswald de Andrade, identificando a evolução estética ideológica do autor por meio do manifesto Pau-Brasil (1925) e o Antropófago (1928); de teses e artigos como “Meu Testamento” (1944) e “A crise da filosofia Messiânica” (1945); de entrevistas presentes no livro Telefonema, parte integrante da coleção: Obras Completas de Oswald de Andrade (Rio de janeiro, 1974); e de sua produção teatral. Toma como ponto de partida a antropofagia como um operador cultural, de modo que a característica mais marcante do escritor, a irreverência, é fomentada e trabalhada por meio da ironia, ferramenta de discurso que Oswald de Andrade utiliza com uma função social, uma arma revolucionária e política. Para tal, traçou-se uma linha entre a produção modernista e a produção teatral de Oswald e desse levantamento bibliográfico, a peça que mais chamou a atenção foi O rei da vela, primeira peça escrita na fase adulta, em 1933, e publicada em 1937 e que somente teve sua primeira encenação 30 anos depois, em 1967, pelo grupo de Teatro Oficina com a direção de José Celso Martinez Corrêa. O grupo realizou um levantamento literário e documental sobre o Oswald de Andrade, através de depoimentos dos atores que receberam a proposta de encenação (em 1934), aos Manifestos, até encontrar a Antropofagia oswaldiana, e dela se utilizarem para concretizar O rei da vela, retomando e usando a antropofagia, essencialmente, como um operador cultural

Comunicação de marcas de moda: nova proposta para a ação do Relações Públicas

This study has the objective of presenting a new suggestion to the public relations professional into the Brazilian fashion business, seeing that, besides promising and little explored, presents social-economic conditions that allow the profession actuation. For this, it has been deeply analyzed the social character of fashion history e its development parallel to the society historical and economic transformations, basing, then, the study of fashion history in Brazil. To understand contemporaneity and the relations which interlace on it, there were used two analyzes about nowadays social order, liquid pos-modernity, from Bauman; and the hypermodernity, from Lipovetsky. In this context, it‟s approached new ways of relating with marks and with products which, since their consumption, are prepared to posterior discard. In the accelerated scenario of marks and consumption, the human relations, more liquids and tenuous, create the urgent possibility of action from on communication professional, who knows to identify the consumers desires and foresee their needs, rendering the tenuous laces stronger and the relationships more solid. This is when the profession of public relations presents itself as a new proposal to create experiences and to tight the loose laces on the consumption era
