An anisotropic model for the mullins effect in magnetoactive rubber-likematerials
(Journal of mechanics of materials and structures, 2016-12)
An anisotropic phenomenological model is proposed to describe the Mullins phenomena for magnetoactive elastomers. The model is based on the use of direction-dependent damage parameters and a set of spectral invariants ...
Biomasa de raíces finas en cuatro estadíos de sucesión del Bosque Seco Tropical y dos estaciones climáticas, Santa Rosa, Costa Rica
(Instituto Tecnológico de Costa Rica, 2011)
In Costa Rica, tropical dry forests had suffered the effects of land change for a long time; Hence, the study of fine roots ( ≤ 2mm diameter) among successional forest stages would allow us to evaluate the degree of these ...
A mitochondrial HSP70 (HSPA9B) is linked to miltefosine resistance and stress response in Leishmania donovani
(BioMed Central, 2016-12)
Background: Protozoan parasites of the genus Leishmania are responsible for leishmaniasis, a neglected tropical disease affecting millions worldwide. Visceral leishmaniasis (VL), caused by Leishmania donovani, is the most ...
Regulation of Msx genes by a Bmp gradient is essential for neural crest specification
(Company of Biologists, 2003-12)
There is evidence in Xenopus and zebrafish embryos that the neural crest/neural folds are specified at the border of the neural plate by a precise threshold concentration of a Bmp gradient. In order to understand the ...
MRKAd5 HIV-1 Gag/Pol/Nef Vaccine-Induced T-Cell Responses Inadequately Predict Distance of Breakthrough HIV-1 Sequences to the Vaccine or Viral Load
(PUBLIC LIBRARY SCIENCESAN FRANCISCO, 2012)
Background: The sieve analysis for the Step trial found evidence that breakthrough HIV-1 sequences for MRKAd5/HIV-1 Gag/Pol/Nef vaccine recipients were more divergent from the vaccine insert than placebo sequences in regions ...
Cotinine reduces depressive-like behavior and hippocampal vascular endothelial growth factor downregulation after forced swim stress in mice
(American Psychological Association Inc., 2014)
Characterization of the Stress-Softening and Permanent Set Effects of Elastomeric Materials
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2008-12-01)
In this work, the application of a phenomenological constitutive model able to predict residual strains of isotropic, incompressible hyperelastic rubberlike materials is studied. It consists in a form of the strain energy ...
