2. Simulação computacional de escoamentos reativos com baixo número Mach aplicando técnicas de refinamento adaptativo de malhas / Computational simulation of low Mach number reacting flows applying adaptive mesh refinement techniques.
It is the main goal of the present work to extend a numerical methodology based on both the use of an adaptive mesh refinement technique (AMR) and the use of a multistep, implicit-explicit time-step strategy (IMEX) to applications involving low Mach number reactive flows. Originally developed for incompressible flows, the Eulerian formulation of that methodo

3. Efeito da acupuntura no manejo da dor aguda de origem dental / Effect of acupuncture in the management of acute pain of dental origin
Introduction: Pain and its relief are old concerns of humanity. Acute pain is a cause of dental demand for health care, especially dental emergency shifts. The demand for welfare and health, makes alternative therapies become complementary to conventional treatments such as acupuncture and bloodletting, recognized as a treatment for pain. Objective: The firs

4. Estimates of covariance components for hygienic behavior in Africanized honeybees (Apis mellifera)
Genetic and phenotypic parameters considering the genetic effect on hygienic behavior of queen and workers from 40 Africanized honeybees colonies were estimated separately. Maternal origin of queens was controlled whereas the paternal was unknown, and different groups of workers were considered in three seasons, October 2006, April 2007 and August 2007, but

5. Estimating total claim size in the auto insurance industry: a comparison between tweedie and zero-adjusted inverse gaussian distribution
The objective of this article is to estimate insurance claims from an auto dataset using the Tweedie and zeroadjusted inverse Gaussian (ZAIG) methods. We identify factors that influence claim size and probability, and compare the results of these methods which both forecast outcomes accurately. Vehicle characteristics like territory, age, origin and type dis

7. Diversidade genética em germoplasma de soja identificada por marcadores SSR, EST-SSR e caracteres agromorfológicos / Genetic diversity in soybean germplasm identified by SSR and EST-SSR markers and agromorphological traits
Many studies have shown that cultivated soybean has a very narrow genetic basis, which generates some problems such as lack of genetic variability, cultivars vulnerability and achievement of a productivity plateau. The challenge is to select within the germplasm which accessions to use in a breeding program. This study aimed to analyze the genetic diversity

8. Orchidaceae nativas da região central de São Paulo, Brasil : florística, interação com forófitos, proposta de novas espécies e propagação in vitro de uma espécie ameaçada de extinção / Native Orchidaceae of the central region of São Paulo, Brazil: floristic, interaction nested with host tree, new species proposed and in vitro propagation of threatened of extinction species
Aiming to know the sorts of Orchidaceae of the central region of the State of São Paulo, from 1996 and more intensively from 2005, visits were carried out in 125 forest fragments of 23 local municípios, with weekly periodicity and also, fortnightly. The collect were assistematics, being each fragment visited in the biggest number of points. The species not

9. A origem do zero
The objective of this research paper is to study the origins of ZERO and the different challenges that have emerged throughout history before ZERO was considered an integral part of mathematics. The references below all show ZERO in different contexts: Sentidos Atribuídos ao Zero por alunos da 6 série, article by Salvador and Nacarato (2003), presented at

10. Stabilization of a locally damped thermoelastic system
We show that the solutions of a thermoelastic system with a localized nonlinear distributed damping decay locally with an algebraic rate to zero, that is, given an arbitrary R > 0, the total energy E(t) satisfies for t > 0: E(t) < C (1 + t)-γ for regular initial data such that E(0) < R, where C and γ are positive constants. In the two-dimensional case, we

11. Polarização do alvo molecular no espalhamento de eletrons / Polarization of molecular target in electron scattering
The aim of this work is the inclusion of polarization effects in the calculations of scattering cross section by using model potentials. The implementation was made in the Schwinger multichannel method with pseudopotentials, using a description of polarization potential with gaussians functions. With this potential we entend to reduce the computational cost

12. ABORDAGEM PRELIMINAR E INTEGRADA DA QUALIDADE DA ÃGUA DA MICROBACIA DO CÃRREGO DA AREIA BRANCA, CAMPINAS - SP / Preliminary and Integrative Assessment of Water Quality of the Micro-basin of CÃrrego da Areia Branca, Campinas, SP
The purpose of this study was to analyze the water quality of the micro-basin of CÃrrego da Areia Branca, through analysis of hydrologic (temperature, dissolved oxygen, pH, conductivity and clarity) and analysis of the benthic community of macroinvertebrates. Samplings were carried out at each fifth day in three distinctive sites of the micro-basin, from Se
