1. COMPUTATIONAL FLUID DYNAMICS (CFD) APPLICATION FOR VENTILATION STUDIES IN BROILER HOUSES
ABSTRACT With the recent increase in the number of acclimatized broiler houses in Brazil, design and adaptation of facilities to withstand the tropical weather conditions enabling the maintenance of ideal conditions without increasing costs have been major challenges. The aim of this study was to evaluate the ventilation system in solid-wall broiler houses u

2. Papel da alça microbiana na dinâmica trófica de um lago de várzea na Amazônia Central
During the hydrologic year of 2007-2008, the lago Catalão, a floodplain lake which is influenced by two of the worlds largest rivers (Solimões and Negro), was studied in terms of the dynamic of water column and the trophic dynamic of the microbial food web. At the beginning of the flood the lago Catalão is influenced by the rio Negro and at the end of thi

3. Evaluation of boom hydraulic sprayers in the region of Uberlândia-MG / Avaliação de pulverizadores hidráulicos de barra na região de Uberlândia-MG
Any and every manner of pesticide application represents environmental risks, which must be minimized by the use of proper knowledge and technology, assuring a sustainable food production. Often, great importance is given to the pesticide and little to the application technique. The identification of the conservation state and mode of use of the sprayers in

4. Simulação da dispersão de poluentes por modelo lagrangeano em condições de vento fraco / Pollutant dispersion simulation by lagrangean model for low \vind speed condition
Neste trabalho, a partir de dados rotineiramente medidos em estações meteorológicas de superfície, estimamos os parâmetros de escala da Camada Limite Planetária (CLP) do experimento OLAD (Over Land Atmospheric Dispersion). Esses parâmetros são muito importantes no processo de dispersão, especialmente no cálculo das parametrizações para os modelos

5. ESPECTROS DE TURBULÊNCIA EM TERRENO COMPLEXO
Throughout this paper a spectral analysis is conducted on the superficial limit layer in complex terrains. The data used were collected in the central part of the state of Rio Grande do Sul, in the Valley of Jacuí River. A 15-meter tower, with fast-response sensors and slowresponse ones, collected data at frequencies of 10 Hz and 1 Hz, in July and August 20

6. Análise dos critérios de estabilidade para projetos de plataformas do tipo monocoluna. / Analysis of the stability criteria of monocolumn type platform design.
To be classified and approved by a classification society, all offshore structures shall be submitted and analyzed according to standard rules. The stability criteria are based on the IMO MODU (International Maritime Organization Mobile Offshore Drilling Units) Code which has reference to almost all types of floating units such as surface, column-stabilized

7. Modelagem e análise de desempenho dinâmico de complexos elétricos contendo centrais eólicas dotadas de geradores síncronos / Modeling and dynamic performance analysis of electric power systems containing wind installations equipped with synchronous generators
New generation resources, with low implantation and operation costs and that provoke the minimum possible impact to the environment, are undoubtedly focuses of attention to all the segments of the society. From this common sense, the alternative or renewable sources of energy, and particularly the wind, have certainly had a significant penetration in the com

9. Influencia do ambiente termico, aereo e acustico de uma maternidade e creche de suinos nas condições laborais do trabalhador / Influence of the farrowing and growing swine thermal, air and acoustic environment in labor conditions of the worker
Swine housing project nowadays has presented some gaps related to the impact of the resulting environment in both animal production and the labor health and security. Future rural constructions might provide more than just shade offer to animal confinement, as the animal welfare demands by consumers increased considerably enhancing the use of new design conc

10. Desenvolvimento de um Modelo Lagrangeano para Dispersão de Poluentes em Condições de Vento Fraco / Desenvolvimento de um modelo lagrangeano para dispersão de poluentes em condições de vento fraco
Atualmente, a busca por soluções analíticas para os problemas de dispersão é um dos principais assuntos de pesquisa na modelagem da dispersão de poluentes. Estas soluções tornam-se importantes devido à intenção de obter modelos de dispersão que geram resultados confiáveis em um tempo computacional pequeno, que são de grande interesse para aplic

11. Ecologia do fitoplÃncton de um ambiente tropical hipersalino (Rio Pisa Sal, Galinhos, Rio Grande do Norte, Brasil)
The environments at the Northeast coast of Rio Grande do Norte State are under strong anthropic stress (mainly oil exploration, salt production and marine shrimp culture expansion etc). The present study was conducted in the Pisa Sal River estuary, which belongs to Galinhos-Guamarà ecocomplex, and provides the main water supply and drainage to the Camarus s
