We investigate the molecular abundances in protostellar cores by solving the gasgrain chemical reaction network. As a physical model of the core, we adopt a result of onedimensional radiation-hydrodynamics calculation, which follows the contraction of an initially hydrostatic prestellar core to form a protostellar core. Temporal variation of molecular abundances is solved in multiple infalling ...

Sport massage can enhance athletic physical performance which is similar to Thai traditional massage but no evidence reports the increase in athletic performance before competition. The purpose of this research was to study effects of the Thai massage program on range of motion (ROM) of lower extremities and vertical jump performance (VJP) in collegiate volleyball players. Twelve males and twel...

Cores are, besides connectivity components, one among few concepts that provides us with efficient decompositions of large graphs and networks. In the paper a generalization of the notion of core of a graph based on vertex property function is presented. It is shown that for the local monotone vertex property functions the corresponding cores can be determined in time.

A incidência de luz em determinados objetos emite diferentes freqüências e tamanhos ondas eletromagnéticas que ao serem captadas pela retina, enviam um sinal para o córtex visual organiza a imagem gera uma determinada coloração, sendo assim percepção da cor é interação entre ondas, olhos cérebro. O presente artigo tem como objetivo revisão literária sobre processo captação até no cérebro discor...
