1. ECONOMIC ANALYSIS OF DIFFERENT HYDRAULIC SPRAYERS USED IN SUGARCANE (Saccharum spp.)
ABSTRACT Brazil is the largest sugarcane producer worldwide. In mills, sugarcane crops are sprayed with agrochemicals using self-propelled, tractor-driven, and aerial hydraulic sprayers. As sugarcane spraying is regularly performed over extensive areas, the machinery to be used should be planned and dimensioned to ensure timely operations without overloading

2. A New Approach for Robust Design Optimization Based on the Concepts of Fuzzy Logic and Preference Function
ABSTRACT: In this study, an efficient methodology is proposed for robust design optimization by using preference function and fuzzy logic concepts. In this method, the experience of experts is used as an important source of information during the design optimization process. The case study in this research is wing design optimization of Boeing 747. Optimizat

3. DESENVOLVIMENTO DE ENSAIO PARA ANÁLISE QUALITATIVA DE BIODIESEL EM MISTURAS DIESEL-BIODIESEL PARA APLICAÇÃO EM POSTOS REVENDEDORES DE COMBUSTÍVEIS
In this study, we developed a method for the visual detection of biodiesel in petrodiesel-biodiesel (BX) blends through the aminolysis of the methyl or ethyl esters of fatty acids that are found in biodiesel and that are absent from diesel and vegetable oils. This method is based on three reactional stages, which produce a dark red and easily visualized comp

4. Investigation on natural frequency of an optimized elliptical container using real-coded genetic algorithm
This study introduces a method based on real-coded genetic algorithm to design an elliptical shaped fuel tank. This method enhances the advantage of the system such as roll stability, and reduces disadvantages like fluid c.g. height and overturning moment. These parameters corresponding to the elliptical tanks with different filling levels are properly optim

5. Análise da influência de impelidores laterais no tempo de mistura em tanques de estocagem de diesel com o uso da fluidodinâmica computacional / Analysis of the influence of side-entry mixers on the mixing time in diesel storage vessels using computational fluid dynamics
The homogenization process of hydrocarbons in large scale storage tanks equipped with side-entry impellers plays an important role in a refinery operation, since the quality of the final products depends on the performance of this process. Computational Fluid Dynamics (CFD) is the most viable technique to evaluate and to optimize this process, as experimenta

6. Elasticidades de curto e longo prazos da demanda por Ãlcool hidratado no Brasil
Since March 2003, with the launch of flex fuel cars, consumption of hydrated alcohol again grows strongly in Brazil. The option of the consumer choice, holder of this technology, which allows the use of hydrated alcohol, gasoline or any mixture of proportion between the two in a single tank of fuel, leads to take as main variable the price of fuels (hydrated

7. Avaliação de risco a saúde humana por exposição ambiental a hidrocarbonetos aromáticos monocíclicos : estudo de caso / Avaliação de risco a saúde humana por exposição ambiental a hidrocarbonetos aromáticos monocíclicos : estudo de caso
Soil and underground water contamination with hydrocarbon compounds can occur as a consequence of leak from the underground storage tanks in fuel service stations. The detection of these leaks normally does not occur immediately neither they are communicated to the responsible public authorities, which do not adequately check the conditions of the service st

8. Produção de celulases e xilanases por Penicillium echinulatum em processo submerso utilizando biorreatores com agitação mecânica e airlift de circulação interna
Cellulolytic enzymes have many uses, particularly in the food, textile, and paper industries. However, their major potential use is in the hydrolysis of cellulose a component of lignocellulosic residues for ethanol fuel production. Among the cellulase-producing microorganisms, mutants of the Trichoderma genus are the most studied and most widely used in the

10. Analise do processo de solda de tanques de combustivel soprados atraves da metodologia de projeto axiomatico / Analysis of fuel tank welding process through axiomatic design
Apesar de todos os avanços tecnológicos, o desenvolvimento de projeto, na grande maioria das vezes, ainda é executado de forma interativa, empírica e intuitiva, baseado unicamente na experiência, inteligência ou criatividade dos engenheiros. O desenvolvimento de processo e máquinas para solda em plástico de tanques de combustível soprados não é ex

11. Ethanol storage tanks location in Brazil: a mixed integer program model application / Localização de tanques de armazenagem de álcool combustível no Brasil: aplicação de um modelo matemático de otimização
The main purpose of this research is to develop a mathematical model intended for strategic analysis of the optimal location and considering suitable volumes for storage ethanol (anhydrous and hydrous) tanks. The Mixed Integer Program - MIP model was based on Brazilian ethanol distribution system. The model considered market parameters as supply, demand, and

12. UTILIZAÇÃO DE Microsternarchus bilineatus (OSTARIOPHYSI, GYMNOTIFORMES, HYPOPOMIDAE) COMO BIOMONITOR: O EFEITO DE COMBUSTÍVEIS AUTOMOTIVOS DERIVADOS DO PETRÓLEO NA DESCARGA DO ÓRGÃO ELÉTRICO
This study evaluated the effect of automotive fuel (gasoline and diesel) on the Electric Organ Discharge (EOD) frequency of Microsternarchus bilineatus (Ostariophysi, Gymnotiform), with the objective of testing the viability of this species as a biomonitor to detect pollutant derived from petroleum. Ten individuals of the species were exposed to concentratio
