Las superóxido dismutasas de Candida glabrata participan en la respuesta a estrés oxidante y se requieren para la biosíntesis de lisina, la integridad del ADN y la supervivencia en fase estacionaria
(2015-02)"El hongo patógeno oportunista Candida glabrata tiene una respuesta al estrés oxidante bien definida. C. glabrata es extremadamente resistente a estrés oxidante e inclusive sobrevive dentro de las células fagociticas. Para ... -
An analytical study of the logarithmic mean temperature difference
(2005)"La media logarítmica de diferencia de temperaturas (LMTD, por sus siglas en inglés) ha causado inconveniencias en diversas aplicaciones tales como ciertos programas de simulación de procesos. Su forma indeterminada es una ... -
El nematodo Caenorhabditis elegans como modelo para evaluar el potencial antihelmíntico de extractos de plantas
(2017-09)"Los nematodos parásitos afectan la productividad pecuaria, dando lugar a pérdidas económicas considerables. Sin embargo, son pocos los antihelmínticos disponibles en el mercado y la resistencia de los parásitos a los ... -
On the kinetic arrest of martensitic transformation in Ni-Mn-In melt-spun ribbons
(2017)"Kinetic arrest (KA) of martensitic transformation (MT) has been observed in as-solidified Ni52.2Mn34.3In13.5 melt-spun ribbons; a characterization by dc magnetization measurements was carried out. These alloy ribbons ... -
On Brusselator and Oregonator as chemical reaction networks: a graph approach
(2009)"This paper shows graph similarities between Brusselator and Oregonator reaction mechanisms, using the jacobian matrix in convex coordinates as an adjacency matrix which defines a weighted directed pseudograph. A linear ... -
Continuous high and low temperature induced a decrease of photosynthetic activity and changes in the diurnal fluctuations of organic acids in Opuntia streptacantha
(2017-10)"Opuntia plants grow naturally in areas where temperatures are extreme and highly variable in the day during the entire year. These plants survive through different adaptations to respond to adverse environmental conditions. ... -
Synchronization of chaotic systems with different order
(2002-03)"The chaotic synchronization of third-order systems and second-order driven oscillator is studied in this paper. Such a problem is related to synchronization of strictly different chaotic systems. We show that dynamical ... -
Estructura-evolución de un modelo de sistema dinámico de terremotos: análisis de correlaciones ocultas de largo alcance
(2015)"Este trabajo se apoya en el análisis-comparación de las series de tiempo generadas por un modelo dinámico de terremotos el cual se presenta como un sistema no lineal de tercer orden que acopla leyes de fricción y ... -
An upper limit for slow-earthquake zones: self-oscillatory behavior through the Hopf bifurcation mechanism from a spring-block model under lubricated surfaces
(2017)"The complex oscillatory behavior of a spring-block model is analyzed via the Hopf bifurcation mechanism. The mathematical spring-block model includes Dieterich Ruina's friction law and Stribeck's effect. The existence of ... -
Lie algebra on synchronization of different systems: a generalized function for Hodgkin-Huxley neurons
(2007)"In this contribution two results are taken: (1) The synchronization of noiseless Hodgkin- Huxley (HH) neurons is possible from robust feedback based on Lie algebra approaches and (2) the fact that, from Lie algebra of ... -
Bioelectrochemical changes during the early stages of chalcopyrite interaction with Acidithiobacillus Thiooxidans and Leptospirillum sp.
(MDPI, 2017)"A bioelectrochemical study of charge transfer in the biofilm-chalcopyrite interface was performed to investigate the effect of surficial reduced sulfur species (RSS), in the form of non-stochiometric compounds or polysulfides ... -
Sincronización generalizada entre sistemas Rössler y Lorenz con dinámica Interna
(2010)"Se investiga la sincronización generalizada (SG) entre los osciladores caóticos Rössler y Lorenz en una configuración maestro-esclavo. Para lograr la sincronización se diseña un controlador escalar por retroalimentación ... -
Grahp and automata in arterial vascular tree of the kidney
(2010-05)"The renal vascular development is not known and occurs through two mechanisms that sometimes overlap: vasculogenesis and angiogenesis. Here we only consider growth through angiogenesis, i.e., the arterial vascular tree ... -
Ag-coated heterostructures of ZnO-TiO2/delaminated montmorillonite as solar photocatalysts
(MDPI, 2017-08)"Heterostructures based on ZnO-TiO2/delaminated montmorillonite coated with Ag have been prepared by sol–gel and photoreduction procedures, varying the Ag and ZnO contents. They have been thoroughly characterized by XRD, ... -
Globulin 11S and Its Mixture with l-DPPC at the Air/Liquid Interface
(2009-12)"Langmuir films of globulin 11S protein, L-dipalmitoylphosphatidylcholine (L-DPPC), and mixtures of both on water and on buffer subphases were studied. Brewster angle microscopy (BAM) was used to characterize in situ the ... -
A Lie-based approach to the general framework of chaotic synchronization
(2003)"Diverese phenomena have been reported on the synchornization of chaotic systems. Therefore, the generalized framework of the chaotic synchronization is an actual scienti¯c debate. Here, a Lie-based geometrical approach ... -
