Maximizing hydrogen production and substrate consumption by Escherichia coli WDHL in cheese whey fermentation
(2013-10)"Fermentative hydrogen production is strongly affected by pH. In order to maximize hydrogen production and substrate consumption in Escherichia coli ΔhycA, ΔlacI (WDHL) cheese whey fermentation, the influence of pH control ... -
Síntesis de pozos cuánticos de GaN/InGaN/GaN en estructura cúbica para emisión sintonizada de luz
(2016-02)"En años recientes la utilización de dispositivos de iluminación de luz blanca de estado sólido ha ido aumentando de forma significativa. El ahorro en energía y por tanto económico a largo plazo que dispositivos como LED's ... -
Exponential stability of linear continuous time difference systems with multiple delays
(2013-10)"Some recent results on exponential stability of linear continuous time difference systems with discrete and distributed delay terms are extended to the case of multiple delays. New sufficient conditions for the exponential ... -
Exponential stability of some linear continuous time difference systems
(2012-01)"In this paper, we consider some classes of linear continuous time difference systems with discrete and distributed delays. For these infinite-dimensional systems, we derive new sufficient delay-dependent conditions for ... -
Expansión de células CD34+ de sangre de cordón umbilical en frascos giratorios
(2014-08)"El transplante de células madre hematopoyéticas está limitado por la cantidad de células CD34+ presentes en las unidades de sangre de cordón umbilical; el objetivo de este trabajo fue obtener la expansión in vitro de ... -
Expansion of human hematopoietic cells from umbilical cord blood using roller bottles in CO2 and CO2-free atmosphere
(2011-04)"In this work, we evaluated the expansion of human hematopoietic stem cells from umbilical cord blood in roller bottles. The Iscove's modified Dulbecco's medium, the Stem Pro 34-SFM medium, and the L-15 Leibovitz's medium ... -
Escherichia coli and its application to biohydrogen production
(2015-03)"Hydrogen is an attractive energy carrier because of its high energy density, and used as a raw material in various chemical processes. Nowadays, hydrogen demand is supplied from non-renewable sources, and alternative ... -
Fermentative biohydrogen production: trends and perspectives
(2008-01)"Biologically produced hydrogen (biohydrogen) is a valuable gas that is seen as a future energy carrier, since its utilization via combustion or fuel cells produces pure water. Heterotrophic fermentations for biohydrogen ... -
Robust stability of integral delay systems with exponential kernels
(2016)"In this chapter the stability analysis via Lyapunov-Krasovskii method is extended to perturbed integral delay systems with exponential kernels. Several sufficient robust stability conditions given in the form of linear ... -
Replicative and integrative plasmids for production of human interferon gamma in Bacillus subtilis
(2010-11)"Integrative and replicative plasmids for the expression driven by the P43 promoter and secretion of recombinant proteins in Bacillus subtilis were constructed. The plasmids named pInt and pRep respectively were tested for ... -
Heterologous expression of a novel psychrophilic Cu/Zn superoxide dismutase from Deschampsia antarctica
(Elsevier, 2009-09)"Superoxide dismutase (SOD) catalyzes the conversion of the superoxide radical (O2−) into oxygen and hydrogen peroxide. Deschampsia antarctica is a plant that grows in Antarctica and survives to extreme low temperature and ... -
Modificación del criterio de Mikhailov para sistemas conmensurados de orden fraccionario
(2017)"En este trabajo se presenta la modificación del criterio de estabilidad de Mikhailov para sistemas lineales fraccionarios de orden conmensurado. Dicha modificación consiste en determinar la medida apropiada del cambio ... -
Indole modifies the central carbon flux in the anaerobic metabolism of Escherichia coli: application to the production of hydrogen and other metabolites
(Elsevier, 2016-12)"Indole is a bicyclic signaling molecule with effects on both eukaryotic and prokaryotic cells. The majority of studies of indole action have been performed with bacteria cultured under aerobic conditions and little ... -
Nitrogen sources impact hydrogen production by Escherichia coli using cheese whey as substrate
(Elsevier, 2013-09)"The impact of nitrogen source on hydrogen production by Escherichia coli WDHL (Delta hycA Delta lacI) strain using cheese whey as a substrate was evaluated. To improve the assimilation of complex proteins such as lactalbumin, ... -
Control of mechanical systems on Lie groups based on vertically transverse functions
(2008-06)"The transverse function approach to control provides a unified setting to deal with practical stabilization and tracking of arbitrary trajectories for controllable driftless systems. Controllers derived from that approach ... -
On the transversality of functions at the core of the transverse function approach to control
(2011-12)"The transverse function approach to control, introduced by Morin and Samson in the early 2000s, is based on functions that are transverse to a set of vector fields in a sense formally similar to, although strictly speaking ... -
Novel fusion protein derived from vasostatin 30 and vasoinhibin II-14.1 potently inhibits coronary endothelial cell proliferation
(2013-07)"Angiogenesis has been considered an important target for cancer therapy. The inhibition of angiogenesis represents a promising strategy for anti-cancer treatment, tumor growth inhibition, and metastasis. Vasostatin 30 ... -
