Methane production enhanced by reduced graphene oxide in an anaerobic consortium supplied with particulate and soluble substrates
(Wiley, 2020)"BACKGROUND Graphene materials have extensively been applied in several industries due to their enhanced properties. Predictably, these materials also end up in wastewaters generated from industrial sectors, and their ... -
Lyapunov-based consistent discretization of stable homogeneous systems
(Wiley, 2021)"In this article, we propose a discretization scheme for asymptotically stable homogeneous systems. This scheme exploits the information provided by a homogeneous Lyapunov function of the system. The main features of the ... -
Stability analysis of PD AQM control for delay models of TCP networks
(Taylor & Francis, 2020)"This paper focuses on the local stability analysis of nonlinear delay models of transmission control protocol/active queue management (TCP/AQM) networks by using a Proportional-Derivative (PD) controller as AQM strategy. ... -
Biorecovery of Metals from a Stainless Steel Industrial Effluent through Denitrification Performed in a Novel Anaerobic Swirling Fluidized Membrane Bioreactor (ASFMBR)
(American Chemical Society, 2020)"A novel technology was developed for the treatment of a stainless steel wastewater, which contains high nitrate concentration (6.8 g N-NO3–/L), acidic pH (pH 3.3), and high concentration of metals. Denitrification was ... -
A Consistent Discretisation method for Stable Homogeneous Systems based on Lyapunov Function
(International Federation of Automatic Control, 2020)"In this paper we propose a discretisation scheme for continuous and asymptotically stable homogeneous systems. This method is based on the dynamics of the system projected on a level surface of a homogeneous Lyapunov ... -
A Switching Controller for a Class of MIMO Bilinear Systems With Time Delay
(IEEE, 2020)"In this paper we propose a switching controller for a class of MIMO bilinear systems with constant delays in both the state and the input. The motivation to consider such a class of systems is that, in the scalar case, ... -
Bacterial biodegradation of diisononyl phthalate: molecular characterization and optimization
(2021)"Di-isononyl phthalate (DINP) is one of plasticizers most employed in the production of plastic materials and belongs to the most important environmental contaminants. In this work, a consortium of saline soil bacterial ... -
Análisis espacio-temporal de la calidad del agua subterránea en el Valle de San Luis Potosí
(2021-05-24)"El objetivo de esta investigación fue analizar espacial y temporalmente la calidad del agua subterránea en el Valle de San Luis Potosí, e identificar procesos naturales y antropogénicos que afectan su calidad. Se recopilaron ... -
Reconocimiento y usos tradicionales de plantas en una comunidad indígena migrante de San Luis Potosí, México
(Sociedad Botánica de México, 2020)Antecedentes: Existen pocas investigaciones sobre el efecto de la migración circular en el conocimiento botánico tradicional de México, particularmente en la Huasteca Potosina. Preguntas: 1) ¿El reconocimiento de las ... -
Synthesis of Bamboo-like Multiwall Carbon Nanotube–Poly(Acrylic Acid-co-Itaconic Acid)/NaOH Composite Hydrogel and its Potential Application for Electrochemical Detection of Cadmium(II)
(MDPI, 2020)"A poly(acrylic acid-co-itaconic acid) (PAA-co-IA)/NaOH hydrogel containing bamboo-type multiwall carbon nanotubes (B-MWCNTs) doped with nitrogen (PAA-co-IA/NaOH/B-MWCNTs) was synthesized and characterized by SEM, absorption ... -
Dust Deposition on the Gulf of California Caused by Santa Ana Winds
(MDPI, 2020)"Numerical simulations revealed a profound interaction between the severe dust storm of 2007 caused by Santa Ana winds and the Gulf of California. The weather research and forecasting model coupled with a chemistry module ... -
Effect of aridity on species assembly in gypsum drylands: a response mediated by the soil affinity of species
(Oxford University Press, 2020)"Previous studies found that plant communities on infertile soils are relatively resistant to climatic variation due to stress tolerance adaptations. However, the species assemblies in gypsum soil habitats require further ... -
Massive Influx of Pelagic Sargassum spp. on the Coasts of the Mexican Caribbean 2014-20: Challenges and Opportunities
(MDPI, 2020)"Since late 2014, the Mexican Caribbean coast has periodically received massive, atypical influxes of pelagic Sargassum spp. (sargasso). Negative impacts associated with these influxes include mortality of nearshore benthic ... -
A Novel Divergent Geminivirus Identified in Asymptomatic New World Cactaceae Plants
(MDPI, 2020)"Cactaceae comprise a diverse and iconic group of flowering plants which are almost exclusively indigenous to the New World. The wide variety of growth forms found amongst the cacti have led to the trafficking of many ... -
Genetic variability of Pun1 gene (Capsaicin synthase) in pungent cultivars of Capsicum annuum of Northern Mexico
(2020)"Background: Capsaicinoids are exclusive of the genus Capsicum and are responsible for fruit pungency. The genetic basis of pungency is not yet fully understood, although several candidate genes have been analyzed including ... -
