Gluon saturation and proton - Anti-proton cross sections
We study proton - anti-proton cross sections in the framework of an updated minijet eikonal model. We propose a different scheme for fixing the parameters, in which we make use of the measured minijet cross section. We ...
Reaction functions for weakly bound systems
(ELSEVIER SCIENCE BV, 2009)
We propose a new technique to analyze total reaction cross sections. In this technique, which has been previously applied to fusion reactions, the experimental data are used to build a dimensionless reaction function, which ...
Sistema de Informação Pré-Natal: análise crítica de registros em um município paulista.
The prenatal assistance is one of the health care pillars. This study aimed to conduct a critical evaluation of the SIS Prenatal in a city of São Paulo State, to compare its data with the local assistance and to verify the ...
Conflict between the classical equivalence principle and quantum mechanics
As far as external gravitational fields described by Newton's theory are concerned, theory shows that there is an unavoidable conflict between the universality of free fall (Galileo's equivalence principle) and quantum ...
The emergence of sex differences in personality traits in early adolescence: A cross-sectional, cross-cultural study
(American Psychological Association, 2015)
Although large international studies have found consistent patterns of sex differences in personality traits among adults (i.e., women scoring higher on most facets), less is known about cross-cultural sex differences in ...
