Effect of an electric field within microscopy focused ion beam (FIB) between manipulator sharp and the ion trap of the electron detector
(2011)"The manipulation of samples with micro manipulators sharps in the normal axis to the observation plane is practically blind in microscopy focused ion beam (FIB) mono beam. The application of a negative potential to the ... -
A New Catalytic System for the Photodegradation of Endocrinal Disruptors: Synthesis and Efficiency Modeling and Optimization
(2015)"Nowadays, the challenge of understanding relationships between catalysts properties and performance in the context of heterogeneous catalysis is a hot topic. Indeed, catalytic processes are generally affected by many ... -
Protection of silver nanoparticles using Eysenhardtia polystachya in peroxide-induced pancreatic beta-Cell damage and their antidiabetic properties in zebrafish
(2018)"Background: The aim was to explore the efficacy of extract of Eysenhardtia polystachya-loaded silver nanoparticles (EP/AgNPs) on pancreatic β cells, INS-1 cells, and zebrafish as a valuable model for the study of diabetes ... -
Analysis of microRNA expression in newborns with differential birth weight using newborn screening cards
(MDPI, 2017)"Birth weight is an early predictor for metabolic diseases and microRNAs (miRNAs) are proposed as fetal programming participants. To evaluate the use of dried blood spots (DBS) on newborn screening cards (NSC) as a source ... -
Distribution of arsenic and risk assessment of activities on soccer pitches irrigated with arsenic-contaminated water
(MDPI, 2018)"The aim of this research was to estimate the risk of human exposure to arsenic due to sporting activities in a private soccer club in Mexico, where arsenic-contaminated water was regularly used for irrigation. For this ... -
Stability of FeVO4 under pressure: an x-ray diffraction and first principles study
(2018)"The high-pressure behavior of the crystalline structure FeVO4 has been studied by means of X-ray diffraction using a diamond-anvil cell and first-principles calculations. The experiments were carried out up to a pressure ... -
Richness and abundance of granivorous vertebrates determine acorn removal patterns in a human modified oak forest
(2018)"Most forests of the Earth have been affected by human activities and this can alter the plant-animal interactions on which depend the functional integrity of these ecosystems. In this study, we assessed the relationships ... -
Tissue carbon concentration of 175 Mexican forest species
(2017)"Reliable calculations of carbon stocks in forest ecosystems are crucial for proper implementation of global warming mitigation policies. Accurate estimations depend upon applying the correct factor of carbon (C) concentration for ... -
Numerical computation of Lyapunov matrices for integral delay systems
(2017)"This paper focuses on the problem of computing Lyapunov matrices for integral delay systems. It is shown that these Lyapunov matrices cannot be computed by means of the existing methods for Lyapunov matrices of differential ... -
Expression analysis of the Arabidopsis thaliana AtSpen2 gene, and its relationship with other plant genes encoding Spen proteins
(2017)"Proteins of the Split ends (Spen) family are characterized by an N-terminal domain, with one or more RNA recognition motifs and a SPOC domain. In Arabidopsis thaliana, the Spen protein FPA is involved in the control of ... -
On computing estimates of the attraction region for a class of nonlinear time-delay systems
(2006)"In this paper, initial estimates of the attraction region for a class of nonlinear time delay systems are proposed. The approach is constructive, and make use of an appropiate Lyapunov-Krasovskii functional. Several ... -
Functional responses of recently emerged seedlings of an endemic Mexican oak (Quercus eduardii) under climate change conditions
(2018)"Background: Climate change will increase temperature and reduce rainfall across temperate forests of Mexico. This can alter tree establishment dynamics within forest and in neighbouring man-made clearings. Hypotheses: ... -
