Shear viscosity of a pion gas resulting from rho pi pi and sigma pi pi interactions
(Amer Physical Soc, 2014-04-02)
We have evaluated the shear viscosity of pion gas with vanishing chemical potential taking into account its scattering with the low mass resonances sigma and rho during propagation in the medium. The thermal width (or ...
Propriedades estruturais e eletrônicas de nanopartículas de Cu modificam a estrutura superficial do cobre e influenciam na atividade catalítica para a reação deslocamento gás água
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2017-08-16)
The Cu catalysts activity is modified by reducible supports, such as cerium and praseodymium oxides. The interaction of these oxides with Cu nanoparticles prevent agglomeration and generate active interface sites. The ...

Durante los últimos años Colombia se ha convertido en un país catalizador de inversión principalmente por su riqueza en materias primas. Tras la reciente crisis financiera en la zona euro y la crisis hipotecaria de 2008, ...
Holobiont effect accounts for more methane emission variance than the additive and microbiome effects on dairy cattle
(2021-05-11)
Rumen microbiota has been previously related to phenotypic complex traits of relevance in dairy cattle. The joint analysis of the host’s genetic background and its microbiota can be statistically modelled using similarity ...
