1. Study of Catalytic Pyrolysis of Biomass Sorghum (Sorghum bicolor L. Moench) Using Design of Experiments and Surface Response Methodology
This study proposes a screen of variables that have an influence on the modification of the bio-oil chemical composition as a unique critical quality attribute (CQA) throughout the pyrolytic process (zeolite, ZSM-5) by using a 24 full factorial design, followed by optimization through a response surface methodology (RSM) based on central composite design (CC

2. Seleção de carvões ativados para adsorção de microcistinas
RESUMO A presença das cianobactérias é uma das grandes preocupações para o tratamento de água, uma vez que esses microrganismos podem ser produtores de metabólitos tóxicos, como as microcistinas (MCs), que não são efetivamente removidas no tratamento usualmente empregado de ciclo completo. Para a remoção dessas toxinas, pode-se, de forma compleme

3. ASSESSMENT OF OZONE AS A PRETREATMENT TO IMPROVE ANAEROBIC DIGESTION OF VINASSE
Abstract This paper presents an assessment of ozone oxidative effects on the biodegradability of sugar cane vinasse, aiming at increasing the methane yield by anaerobic digestion of this effluent. Furthermore, as a new approach, an economic balance of this process was made. Using a bench scale reactor, ozone was applied at 60, 120, 180, 240 mgO3.gCOD-1 doses

4. Composition and spatial distribution of subtidal decapoda on the "Reef Coast", northeastern Brazil, evaluated through a low-impact visual census technique
This study investigated the composition and spatial distribution of the sublittoral decapods on the reefs of Porto de Galinhas Beach, southern coast of Pernambuco, Brazil, through the Underwater Visual Census technique. Data were collected monthly, at night during full-moon tides in low tide periods from June 2004 to May 2005, using SCUBA diving and a visual

5. Estudo de técnicas conceituais de recapeamento de quadril de cães / Study of conceptual techniques for dogs hip resurfacing
The study conceptually describes a surgical model for dog hip resurfacing technique. Hip arthroplasty was developed to restore joint mobility and relieve of human patients pain. In animals, especially dogs, total arthroplasty is a surgical procedure commonly used to correct traumatic, degenerative and inflammatory hip diseases and alleviate pain. The resurfa

6. Effects of differential weekly frequencies of weight training on body composition and motor capacities in older men / Efeitos de diferentes frequencias semanais de treinamento com pesos sobre a composição corporal e capacidades motoras em homens idosos
The effects of weight training made with different intensities, frequencies and volumes provide beneficial answers and are well spread among young people and athletes. However, studies that look for the effects of weight training held at different frequencies weekly are limited to elder populations. So, the purpose of this study was to analyze and compare th

7. Estudo experimental da influência de um ressonador de volume variável na massa de ar admitida por um motor de combustão interna
The dynamic of intake manifold admission on internal combustion engines involves parameters such as length, diameter, camshaft rotation and other geometries and accessories. The alternative movements of the admission valves and piston produce the phenomena of generation of pressure waves that spread through the conduit. Such waves, if well used, can increase

8. Análise da produção do antitumoral retamicina em cultivos contínuos de Streptomyces olindensis ICB20 utilizando planejamento fatorial. / Analysis of the production of the antitumor drug retamycin in continous cultures of Streptomyces olindensis ICB 20 using factorial desing.
The aim of this project was to study the production of retamycin in bench-top bioreactors by Streptomyces olindensis ICB20 in continuous cultures in order to evaluate the influence of the agitation rate (N=300, 500 or 700 rpm), the dissolved oxygen concentration (20%, 50% or 80%) and the specific growth rate (µ=0.05, 0.15 or 0.25 h-¹). A full factorial exp

10. Comunidade de CrustÃceos DecÃpodos InfralitorÃneos dos Recifes da Praia de Porto de Galinhas (PE)
Northeastern Brazilian coral reefs, as found in Porto de Galinhas beach â PE, are known as areas of complex and diverse biological interactions and high biological productivity (primary productivity). In addition, they represent a reproductive zone, and serve as nursery, shelter and alimentation source for a major part of the marine fauna. Porto de Galinhas

11. Aspects of seeds germination and influence of light on the development, leaf anatomy and chemical composition of essential oil in Ocimum gratissimum L. / Aspectos da germinaÃÃo das sementes e influÃncia da luz no desenvolvimento, anatomia foliar e composiÃÃo quÃmica do Ãleo essencial em Ocimum gratissimum L.
Before the need to deepen the knowledge about medicinal flora, the species Ocimum gratissimum L., an important producer of essential oil much utilized as a phytotherapeutic, was selected. The main objectives in this work were to evaluate physiologic aspects of germination and storage of seeds as well as to investigate growth leaf anatomy and accumulation of

12. Estudo da incineração catalitica de compostos volateis organicos em planta piloto
The work presents the study of oxidation of hidrogen over Pallladium supported on Alumina. The catalyst was prepared by impregnation of the precursor salt PD CL IND. 2 on Alumina particles sized by extrusion and sintering. The salt decomposing at the surface was done by thermal treatment at the temperature of 400 DEGREES C followed by reduction with hydrogen
