Etiopatogenia e tratamento do deslocamento de abomaso em bovinos leiteiros de alta produção

The dairy business is in constant development, in order to achieve better results and higher profits to the producer, and this search for improvement has led to the selection of a herd more productive. But this has caused some problems heightened, among them the displacement of the abomasum, a disease that affects much of the high producing dairy herd. The main reasons are apparently related to the feeding management, with the abrupt changes that the animal suffers in the post partum period, with diseases that would cause abomasal atony favoring its displacement, among others. When affected, the animals lose their appetite and in milk production, and may even, in severe cases, death to come. Treatments described in literature are varied and there are conservative and chirurgical methods. The choice of a particular technique depends on the financial condition of the producer, the economic value of the cow and from personal experience and technique of the veterinarian. Understanding the clinical implications of displaced abomasum is necessary not only for its animal identification in the field and its appropriate treatment but also for finding the errors and inadequacies in the management system of production that trigger this disease

Implementação de produção enxuta em uma empresa de manutenção de equipamentos rotativos

This graduation work presents the implementation of the key concepts of lean thinking in a maintenance workshop of rotating equipment, analyzing all the administrative and workshop processes. The pursuit of quality and client satisfaction at lower costs has generated a lot of competition between organizations, which use the practices of lean manufacturing as tools for processes improvement, aiming to eliminate wastes, being this, the work objective. And, unlike a manufacturing system, where the product goes through certain stages until its conclusion, the workshop does not have a default sequence that is repeated routinely on all machines. Thus, it demonstrates a possibility of application of lean tools in a different way of the common used in the lean manufacturing

Estudo da produção de hidrogênio eletrolítico a partir de fontes eólica, solar e hidrelétrica

Introduces technical, economic and environmentally competitive solutions in the energy market is a great challenge for society. This work examines each of these aspects considering the production of electrolytic hydrogen with energy from wind power, solar and hydropower, in order to ensure an overview of this energy carrier. Initially, an assessment of the technical aspects is made addressing existing electrolysers technologies, its main characteristics and differences. The geographical distribution of wind, solar and hydroelectric potential in Brazil is also mapped, and a configuration scheme of a hydrogen production system is discussed. Subsequently, the economic analysis calculates the cost of investment in the alkaline electrolyser of 60 Nm³ / h, similar to the Brazilian bus powered by hydrogen project, coordinated by EMTU. Since the main input of electrolysis is electricity, is analyzed the latest energy auctions of each primary source and it is calculated the cost of production of the wind, solar and hydropower hydrogen. Postponed to this, are investigated the intrinsic environmental impacts of electricity generation process, proposing a readjustment of an indicator of ecological efficiency for the production of hydrogen. Finally, the work discusses the concept of externalities and demonstrates how the incorporation of external costs can leverage the hydrogen economy. In short, it is evident that the wind and hydroelectric hydrogens are more promising compared to solar hydrogen, whether in the economic aspect, because it achieved lower costs, whether in the environmental aspect, because it reached the highest ecological efficiency

Decisão making or buying: uma aplicação em células de manufatura de uma indústria de produção mecânica

In order to maintain the competitiveness the companies seek for cost reduction and resource optimization. A product or service price is calculated considering direct and indirect costs involved in its fabrication, which means that if an intern indirect process is optimized, the final price of the product is also reduced and becomes more interesting to the final costumer. Considering this reasoning, the companies must evaluate each of their processes and optimize them. It is common to outsource intern products manufacturing as a cost reduction strategy, nevertheless when there are already resources and capability to produce the own goods, it becomes necessary to evaluate the economic gain that each strategy - make or buy - generates. This paper aims to evaluate the necessary support to take a decision regarding making or buying in a production cell of hoses based in the value of economic cost, system cost and decision process
