1. Classification of soil respiration in areas of sugarcane renewal using decision tree
ABSTRACT: The use of data mining is a promising alternative to predict soil respiration from correlated variables. Our objective was to build a model using variable selection and decision tree induction to predict different levels of soil respiration, taking into account physical, chemical and microbiological variables of soil as well as precipitation in ren

2. Computation of air chemical equilibrium composition until 30000K - Part I
Abstract An algorithm was developed to obtain the air chemical equilibrium composition. The air was considered to be composed of 79% N2 and 21% O2, and the models are 5 chemical species, N2, O2, NO, N, O, and 7 chemical species, N2, O2, NO, N, O, NO+, e-, respectively. The air chemical equilibrium composition is obtained through the equilibrium constants met

3. Simulation software development for multibody systems / Desenvolvimento de uma ferramenta computacional para simulação de sistemas mecânicos multicorpos
The mathematical simulation is a very important tool to reduce production costs in new projects of agricultural machines. This work consists of a simulation software development for multibody systems (MBS), called FSSM (tool for simulation of mechanical systems), with appropriate functionalities for manufacturers of agricultural machines, using the AutoCAD g

5. "Avaliação da força de tração da sela modificada para prótese" / Evaluation of traction force in modified saddle for prosthesis.
From the planning to the execution of the tissue-dento-supported prosthesis, the literature presents a range of works standing out the difficulties related to the prosthesis performance when facing distinctive tissues, tooth and fibromucous. These works approach the biomechanical problems and the damages suffered by osseous tissues and teeth under pressure,

6. Modelagem matematica e simulação numerica de um sistema reacional composto por reatores tipo tanque agitado e tubular em processos de polimerização
The present work consists of a mathematical modeling and numerical simulation of a solution polymerization reaction, using as study case the polystyrene. The reaction system is composed by a continuous stirred tank reactor (CSTR) for prepolymerization, associated in series with a tubular reactor to carry out the reaction until high conversion values. A simpl

7. Estudo do comportamento mecanico de comandos desbalanceados pelo metodo de elementos finitos
The work treats the finite element modeling of the static behaviour of drillstrings equiped with bottom hole assemblies composed by unbalanced drill collars. The drillstring was discretized in beam-column elements having geometric non linearity. The Newton-Raphson Method with an incremental loading scheme was used to obtain the solution of the non linear sys

8. A Comparative Structural Analysis of the Flagellin Monomers of Caulobacter crescentus Indicates that These Proteins Are Encoded by Two Genes
The flagellum of Caulobacter crescentus is composed of two flagellin polypeptide monomers which are distinguished by molecular weight and are closely related by biochemical and immunological criteria (C. Lagenaur and N. Agabian, J. Bacteriol. 132:731-733, 1977). The synthesis and assembly of these two flagellin proteins are developmentally regulated, and the
