    Phyton-International Journal of Experimental Botany, Vol.88, No.3, pp. 239-252, 2019, DOI:10.32604/phyton.2019.06887

    Abstract The lack of knowledge of plant tolerance and differential response to aluminum (Al) encouraged many researchers, in the last decade, to elucidate Al toxicity and tolerance mechanisms. The current study reported the impact of Al, a toxic element with negative effects on plant growth and development, in halophytic plant Tamarix gallica. Plants were subjected to different Al concentrations (0, 200, 500 and 800 μM) with or without NaCl (200 mM) supplementation. Growth, photosynthesis and mineral content were assessed. Al stress had a significant decrease on shoots’ biomass production between 19 to 41%, and a little variation on chlorophyll content and… More >

    Modeling The Nutrientsbehavior in Intervertebral Discs: A Boundary Integral Simulation

    Y. González, F. Nieto, M. Cerrolaza∗,†

    Molecular & Cellular Biomechanics, Vol.10, No.1, pp. 67-84, 2013, DOI:10.3970/mcb.2013.010.067

    Abstract It is a well-known fact that computational biomechanics and mechanobiology have deserved great attention by the numerical-methods community. Many efforts and works can be found in technical literature. This work deals with the modeling of nutrients and their effects on the behavior of intervertebral discs. The numerical modeling was carried out using the Boundary ELement Method (BEM) and an axisymmetric model of the disc. Concentration and production of lactate and oxygen are modeled with the BEM. Results agree well enough with those obtained using finite elements. The numerical efforts in the domain and boundary discretizations are minimized using the BEM.… More >
