Proteinograma sérico, com ênfase em proteínas de fase aguda, de bovinos sadios e bovinos portadores de enfermidade aguda de ocorrência natural

Nas últimas décadas, as proteínas de fase aguda (PFAs) tornaram-se biomarcadores de escolha em medicina humana para identificação e monitoração de doenças. Não há razão para imaginar que tais pesquisas clínicas não sejam igualmente úteis na medicina veterinária. Com o objetivo de verificar a importância das PFAs como biomarcadores de doenças inflamatórias em bovinos, determinou-se o proteinograma sérico, por meio da técnica de eletroforese SDS-PAGE, com interesse especial nas PFAs. Foram utilizados 30 animais, distribuídos em dois grupos: 15 bovinos sadios e 15 bovinos doentes (cinco com mastite estafilocócica, cinco com fotossensibilização e cinco com onfaloflebite). Os animais foram submetidos a colheitas diárias de sangue durante sete dias, enquanto internados no Hospital Veterinário da Unesp, Campus de Jaboticabal. Ceruloplasmina e haptoglobina apresentaram elevação significativa em animais acometidos por mastite, fotossensibilização e onfaloflebite (275,17% e 343,71%; 175,17% e 230,19%; 114,47% e 144,47%, respectivamente). A α1-glicoproteína ácida foi um bom biomarcador apenas em animais com mastite e fotossensibilização, elevando, respectivamente, suas concentrações séricas em 198,14% e 145,89%. Fibrinogênio mostrou-se um indicador confiável apenas em bovinos com mastite, com elevação de 146,5% em relação ao grupo sadio. Ficou clara a diferença na responsividade de distintas PFAs frente a diferentes estímulos inflamatórios. Ceruloplasmina e haptoglobina foram biomarcadores mais sensíveis e, portanto, mais confiáveis entre as PFAs estudadas nessa espécie.

Ocorrência de contusões em carcaças bovinas em frigorífico

The animal welfare is a series of practices that involves the maintenance of psychological and physiological freedoms of animals, to them remain healthy until slaughter and provide a satisfactory quality carcass and to avoid unnecessary suffering to animals. One way to evaluate the animal welfare is monitoring the occurrence of bruises on carcasses that is an indicative of inadequate management of the animals. The present study aimed to evaluate the occurrence of bruises in cattle carcasses at a slaughterhouse located in the Midwest Region of the State of São Paulo, Brazil. Was applied a check-list that determined the presence of bruises, the location and severity of them, ranking among scores I to III. Was observed in 98% (880/898) of the animals the presence of contusion. The Grade I injuries in the region of the hips at half carcasses had higher incidence with an average of 61.8% between the right and left sides. Could be observed multiple lesions in several animals slaughtered. In 133 animals observed were removed 15.6 kilograms of material only the injured region only of the hips, demonstrating economic losses to cattle farmers and industries for failures in animal welfare practices. The inappropriate pre-slaughter management compromises animal welfare and the quality of carcasses, discrediting our products on international meat trade and consisting in economic losses to the national cattle herds.

Uso da calculadora nas aulas de Matemática: possibilidades e percepção de licenciandos e professores

The objective of this work is to analyze teaching situations with the use of calculator inside classroom aiming to understand its function and potential to the learning of Mathematics. A survey was carried out about the students and teachers’ conceptions concerning the use of calculator as an auxiliary tool in the learning of Math . The first part of the research is based by means of official documents (Parâmetros Curriculares Nacionais (PCN) , Proposta Curricular do Estado de São Paulo, Guia do Programa Nacional do Livro Didático (PNLD)) , researches and other publications , characterizing by a bibliographic study. The survey with the participants— Math students and teachers acting in public or private schools of São Paulo state— was done through a questionnaire and interviews . The results show that most part of interviewed people are in favor of the use of calculator in the classroom . However , a big part of this number still consider it only as a tool to speed calculations with high numbers or decimals . It was verified that teachers who have recently graduated and have taught for a short period of time accept and comprehend the role of calculator more easily in some activities and consider it as an useful and auxiliary tool to the students’ learning

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

Influência da geometria de corte no torneamento do eucalipto sp

In contrast to what happened in the past where it was possible to select which species had a lower degree of variation, it is now necessary to use fast-growing species with efficient processing. For that we use the wood of Eucalyptus sp and studies related to the machining processes and their parameters such as wear of cutting tools and roughness. The present work aims to analyze the influence of geometry of cutting tools of high speed steel and the influence of the diameter of the final pieces in the process of turning wood of Eucalyptus sp in relation to power consumption, roughness, temperature machining, chip formed and wear of cutting tools. It was observed that the smaller the diameter of the end parts and greater wear of the tools, the worse quality of the machined surfaces and the greater the power consumed in the process of machining
