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 ... -
Identification of calcium stress induced genes in amaranth leaves through suppression subtractive hybridization
(Elsevier, 2011-11)"Calcium (Ca2+) is a critical ion for the growth and development of plants and plays an important role in signal transduction pathways in response to biotic and abiotic stresses. We investigated the Ca2+ stress responsive-genes ... -
Identification of yeast and bacteria involved in the mezcal fermentation of Agave salmiana
(Wiley, 2008-06)"Aims: To identify the yeast and bacteria present in the mezcal fermentation from Agave salmiana. Methods and Results: The restriction and sequence analysis of the amplified region, between 18S and 28S rDNA and 16S rDNA ... -
Braid solutions to the action of the Gin enzyme
(2010-08)"The topological analysis of enzymes, an active research topic, has allowed the application of the tangle model of Ernst and Sumners to deduce the action mechanism of several enzymes, modeled as 2-string tangles. By first ... -
New results on robust exponential stability of integral delay systems
(2016-06)"The robust exponential stability of integral delay systems with exponential kernels is investigated. Sufficient delay-dependent robust conditions expressed in terms of linear matrix inequalities and matrix norms are derived ... -
Stability conditions for integral delay systems
(2010)"In this paper we consider a special class of integral delay systems arising in several stability problems of time‐delay systems. For these integral systems we derive stability and robust stability conditions in terms of ... -
Biohydrogen production by the psychrophilic G088 strain using single carbohydrates as substrate
(Elsevier, 2016-05)"The production of biohydrogen by psychrophilic G088 strain ([EU636029]), closely related to Polaromonas rhizosphaerae ([EF127651]) was evaluated using xylose, glucose, fructose, galactose, lactose or sucrose as a carbon ... -
Sobre la estabilidad de controladores PD en redes TCP/AQM
(2016)"En este artículo se aborda el problema de estabilización de modelos con retardo de redes tipo Protocolo de control de transmisión/Manejo activo de cola (TCP/AQM por sus siglas en inglés) mediante el uso de un controlador ... -
Hydrogen production by Escherichia coli ΔhycA ΔlacI using cheese whey as substrate
(Elsevier, 2010-01)"This study reports a fermentative hydrogen production by Escherichia coli using cheese whey as substrate. To improve the biohydrogen production, an E. coli ΔhycA ΔlacI strain (WDHL) was constructed. The absence of hycA ... -
A review of definitions of the Himalayan Main Central Thrust
(2017-09)"Most workers regard the Main Central Thrust (MCT) as one of the key high strain zones in the Himalaya because it accommodated at least 90 km of shortening, because that shortening exhumed and buried hanging wall and ... -
Estimation of hydrogen production in genetically modified E. coli fermentations using an artificial neural network
(Elsevier, 2010-12)"Biological hydrogen production is an active research area due to the importance of this gas as an energy carrier and the advantages of using biological systems to produce it. A cheap and practical on-line hydrogen ... -
Estimates of the attraction region for a class of nonlinear time-delay systems
(2007)"In this paper, we propose various estimates of the attraction region for a class of nonlinear time-delay systems of the form forumla The approach is constructive and makes use of a Lyapunov–Krasovskii functional associated ... -
Computing non-fragile PI controllers for delay models of TCP/AQM networks
(2009)"This article focuses on the stabilisation problem of fluid-flow delay models of transmission control protocol/active queue management (TCP/AQM) networks by using a proportional-integral (PI) controller as AQM strategy. ... -
Environmental context for the terminal Ediacaran biomineralization of animals
