Los pobladores nativos de México se han caracterizado por poseer conocimiento tradicional sobre las especies de flora y fauna de los ambientes donde habitan, así como por sus prácticas de aprovechamiento. En este estudio se documentó el uso tradicional de…

Adaptive finite element methods (FEM) have been widely used in applications for over 20 years now. In practice, they converge starting from coarse grids, although no mathematical theory has been able to prove this assertion. Ensuring an error reduction rate…

A new computable a posteriori error estimator is introduced, which relies on the solution of small discrete problems on stars. It exhibits built-in flux equilibration and is equivalent to the energy error up to data oscillation without any saturation assumption.…

Data oscillation is intrinsic information missed by the averaging process associated with finite element methods (FEM) regardless of quadrature. Ensuring a reduction rate of data oscillation, together with an error reduction based on a posteriori error estimators, we construct a…

A produção animal nos ecossistemas do semi-árido é influenciada pela variabilidade espacial e interanual da oferta quantitativa e qualitativa de recursos forrageiros. A dinâmica da acumulação de fitomassa para a maioria das diferentes espécies da caatinga é pouco conhecida, o…

This paper suggests that a new form of racialization is being produced in the information age through developments and innovations in communication technologies. Increasingly, racial knowledge is being constructed from seemingly neutral and unrelated pieces of information, which are collected,…

Estudo do tipo quase-experimental que objetivou apresentar os Índices de Satisfação no Trabalho (ISTs) de uma equipe de enfermagem de uma UTI-adulto e as atividades efetuadas para sua melhoria. Participaram 8 enfermeiras e 9 auxiliares de enfermagem. Todos os requisitos…
