Abordaje práctico sobre cómo mejorar el bienestar en los bovinos

Current challenges of humanity require a new paradigm for animal production, and invest time and attention to the development of new production techniques that take into account the principles of sustainability and animal welfare science. To do this, we must be committed to promoting animal welfare and health, ensure environmental sustainability, consumer satisfaction and profitability for producers. To change our relationship with animals there is no need for changes in market conditions or large investments, it is enough to know better the needs of the animals we raise, the management system adapted to its characteristics. Even in the most favorable management conditions, on farms that have technological resources and trained personnel, there is much to change, especially in the daily management of the animals. Some of the risks more evident in the traditional systems of beef production are: problems during parturition, morbidity and mortality of calves, lack of shade in the pastures, improper handling of animals, risk of injury, inadequate infrastructure, poor management practices during routine processing (marking, castration, vaccination, dehorning), poor welfare during loading, transport, unloading and slaughter. To remedy this, you can adopt good management practices, which have been shown to reduce risk and improve the welfare of cattle in different stages of the production chain. The objective of this review is to show some of the risks that reduce the welfare of cattle and examples of how the adoption of best management practices impact on improving the productivity of these production systems. Finally, some indicators for assessing welfare in production systems are shown.

Humanização na Atenção à Saúde do Idoso

O artigo discute as práticas de assistência, políticas, estratégias e ações governamentais formalizadas para a saúde do idoso, visto que, embora o tema humanização se faça presente em várias discussões e que, inclusive, tornou-se diretriz da tão aclamada Política Nacional de Humanização, esses pacientes enfrentam, ainda, vários obstáculos para assegurar alguma assistência à saúde. À desinformação e ao desrespeito aos cidadãos da terceira idade somam-se a precariedade de investimentos públicos para atendimento às necessidades específicas dessa população, a falta de instalações adequadas, a carência de programas específicos e de recursos humanos. Dessa forma, faremos uma reflexão sobre a humanização na assistência à saúde focada nessa população, primeiramente fazendo um resgate da humanização nos diversos cenários do setor saúde, considerando a valorização dos diferentes sujeitos implicados nesse processo, para que o cuidado dessa especial e crescente fatia da população seja realizado de forma humanizada, visto ser este um paciente especial que requer um atendimento diferenciado.

Evaluation of the thermal shrinkage of titanium and the setting and thermal expansion of phosphate-boded investments

Statement of problem. There are few studies on titanium casting shrinkage, and phosphate-bonded investments for titanium casting have not produced appropriate marginal fit.Purpose. The purpose of this study was to determine the thermal shrinkage of titanium and the setting and thermal expansion of 3 phosphate-bonded investments.Material and methods. The thermal shrinkage between the melting temperature and room temperature was calculated using a titanium thermal expansion coefficient. The thermal and setting expansion were measured for 3 phosphate bonded investments: Rematitan Plus (RP) specific for titanium, Rema Exakt (RE), and Castorit Super C (CA), using different special liquid concentrations (100%, 75%, and 50%). Setting expansion was measured for cylindrical specimens 50 mm long x 8 mm in diameter with a transducer. The heating and cooling curves were obtained with a dilatometer (DIL 402 PC). The total expansion curve was drawn using software, and temperatures to obtain expansion equivalent to titanium casting shrinkage were determined (n=5). In addition, the total expansion of the control group (RP at 430 degrees C) was measured, as well as the temperatures at which the other groups achieved equivalent total expansion (n=5). Data were analyzed by 1-way ANOVA and the Tukey HSD test (alpha=.05).Results. Titanium casting shrinkage was estimated as 1.55%. RP did not achieve this expansion. RE achieved expansion of 1.55% only with a special liquid concentration of 100% at 594 degrees C. CA with all special liquid concentrations attained this expansion (351 degrees C to 572 degrees C). Total expansion of the control group was 0.86%, and the other groups reached that expansion within the range of 70 degrees C to 360 degrees C.Conclusions. Only RE and CA demonstrated sufficient expansion to compensate for titanium casting shrinkage. All groups reached total expansion equivalent to that of the control group at significantly lower temperatures.

Effect of phosphate-bonded investments on titanium reaction layer and crown fit

This study analyzed the reaction layer and measured the marginal crown fit of cast titanium applied to different phosphate-bonded investments, prepared under the following conditions (liquid concentration/casting temperature): Rema Exakt (RE) - 100%/237°C, 75%/287°C, Castorit Super C (CS)-100%/70°C, 75%/141°C and Rematitan Plus (RP)-100%/430°C (special to titanium cast, as the control group). The reaction layer was studied using the Vickers hardness test, and analyzed by two way ANOVA and Tukey's HSD tests (α = 0.05). Digital photographs were taken of the crowns seated on the die, the misfit was measured using an image analysis system and One-way ANOVA, and Tukey's test was applied (α = 0.05). The hardness decreased from the surface (601.17 VHN) to 150 μm (204.03 VHN). The group CS 75%/141°C presented higher hardness than the other groups, revealing higher surface contamination, but there were no differences among the groups at measurements deeper than 150 μm. The castings made with CS - 100%/70°C presented the lowest levels of marginal misfit, followed by RE -100%/237°C. The conventional investments CS (100%) and RE (100%) showed better marginal fit than RP, but the CS (75%) had higher surface contamination.

The Brazilian Seismographic Integrated Systems (BRASIS): Infrastructure and data management

In geophysics and seismology, raw data need to be processed to generate useful information that can be turned into knowledge by researchers. The number of sensors that are acquiring raw data is increasing rapidly. Without good data management systems, more time can be spent in querying and preparing datasets for analyses than in acquiring raw data. Also, a lot of good quality data acquired at great effort can be lost forever if they are not correctly stored. Local and international cooperation will probably be reduced, and a lot of data will never become scientific knowledge. For this reason, the Seismological Laboratory of the Institute of Astronomy, Geophysics and Atmospheric Sciences at the University of São Paulo (IAG-USP) has concentrated fully on its data management system. This report describes the efforts of the IAG-USP to set up a seismology data management system to facilitate local and international cooperation. © 2011 by the Istituto Nazionale di Geofisica e Vulcanologia.

Application of ontologies in peer-to-peer database with routing queries based on ant colony algorithm

A significant set of information stored in different databases around the world, can be shared through peer-topeer databases. With that, is obtained a large base of knowledge, without the need for large investments because they are used existing databases, as well as the infrastructure in place. However, the structural characteristics of peer-topeer, makes complex the process of finding such information. On the other side, these databases are often heterogeneous in their schemas, but semantically similar in their content. A good peer-to-peer databases systems should allow the user access information from databases scattered across the network and receive only the information really relate to your topic of interest. This paper proposes to use ontologies in peer-to-peer database queries to represent the semantics inherent to the data. The main contribution of this work is enable integration between heterogeneous databases, improve the performance of such queries and use the algorithm of optimization Ant Colony to solve the problem of locating information on peer-to-peer networks, which presents an improve of 18% in results. © 2011 IEEE.
