1. Performance of common snook subjected to different feeding frequencies and rates using automatic feeders
Resumo: O objetivo deste trabalho foi avaliar o desempenho do robalo-flecha (Centropomus undecimalis) submetido a diferentes taxas e frequências alimentares com o uso de alimentadores automáticos. Dois experimentos, com duração de 60 dias cada um, foram realizados. No primeiro, 20 peixes por tanque foram distribuídos em três taxas alimentares de: 5, 10

2. A supervision and control tool based on artificial intelligence for high cell density cultivations
High cell density cultivations of recombinant E. coli have been increasingly used for the production of heterologous proteins. However, it is a challenge to maintain these cultivations within the desired conditions, given that some variables such as dissolved oxygen concentration (DOC) and feed flow rate are difficult to control. This paper describes the sof

3. Energetic use of wood waste in one center for the production of red ceramics in São Paulo State / Uso energético de resíduos madeireiros em um pólo de produção de cerâmicas vermelhas do Estado de São Paulo
The use of forest biomass is an important alternative of renewable energy source, economic, technical and environmentally viable, fighting for space with other energy sources, more expensive or non-renewable, such as natural gas, electricity, diesel and LPG. Within the industrial sector, biggest consumer of biomass energy, the segment of red ceramics represe

4. Do broilers prefer to eat from a certain type of feeder?
This study compared three types of feeders for broilers: Fênix, Tube and Automatic feeders. Bird's feeding behavior and preference were considered in this the evaluation. Preference was assessed by examining birds' behavioral activities, such as eating, standing and lying around the equipments, and meal duration as function of the environmental variables. D

5. Risk factors and likelihood of campylobacter colonization in broiler flocks.
Campylobacter was investigated in cecal droppings, feces, and cloacal swabs of 22 flocks of 3 to 5 week-old broilers. Risk factors and the likelihood of the presence of this agent in these flocks were determined. Management practices, such as cleaning and disinfection, feeding, drinkers, and litter treatments, were assessed. Results were evaluated using Odds

7. Comparative analisys of the distribution of familier Salpidae and Doliolidae in relation to total zooplankton on the southeastern continental shelf of Brazil by means of semi-automatic techniques of identification and enumeration / Análise comparativa da distribuição das famílias Salpidae e Doliolidae em relação ao zooplâncton total na plataforma continental sudeste do Brasil por meio de técnicas semi-automáticas de identificação e contagem
The abundance of thaliaceans and its relation to other zooplankton groups, as well as salp grazing impact, were studied on the southeastern shelf of Brazil based on samples collected during summer 2002. Salps occurred at higher numbers on the inner shelf, while doliolids were more abundant on the outer shelf. Both taxa were found mainly in the upper layers o

9. Development of automatic methods for evaluating dairy cows behavior in confinement system / Desenvolvimento de metodos automatizados para avaliação do comportamento de vacas leiteiras em sistema de confinamento
The current tendency of the milk production sector is to become more precise and economically feasible. It is known that differences in microclimate cause changes in animal behavior; however, conventional measures taken nowadays are evasive and can produce misinterpretation of the results. The current experiment was carried out in a commercial farm in São P

10. Desenvolvimento de uma desfribadeira para obtenção da fibra da folha do abacaxi
No ano de 1998 foi patenteada uma desfibradeira que foi desenvolvida no laboratório de Engenharia Têxtil da UFRN, com objetivo de desfibrar a folha do abacaxi, com apoio do CNPq e BNB. O presente trabalho objetiva desenvolver uma desfibradeira automatizada com a mesma finalidade e se buscou a fabricação de uma nova desfibradeira com sistema semi-automát

12. Lung function and respiratory symptoms in pig farmers.
In a pilot study to investigate the health effects of swine confinement work on the respiratory tract pulmonary function tests and a questionnaire for respiratory symptoms were used. Complete data, including qualitative exposure information, were gathered for 132 owners of fattening, breeding, or closed pig farms. All measured pulmonary function values, exce
