Optimización del Tratamiento Químico y Térmico de Esferas de Carbono para Mejorar su Rendimiento como Supercapacitores
(2024-07-02)"In this work, a systematic study was carried out on the effect of temperature on the oxidation process of carbon spheres (CSs) to improve their capacitive performance. CSs were treated from naphthalene with HNO3 and H2SO4 ... -
Efecto de un cuarto elemento sobre la histéresis de la transformación martensítica de una aleación Ni-Mn-Ti
(2024-07)"Se elaboraron aleaciones Ni-Mn-Ti, mediante fusión en horno de arco, con el fin de encontrar composiciones para una aleación monofásica; de las cuales la que básicamente presentó una fase fue Ni47Mn43Ti10. A partir de ... -
Characterization of ABC-type transporters in Candida glabrata.
(2024-07)"Candida glabrata is an opportunistic fungal pathogen that accounts for approximately 25% of cases of invasive candidiasis. Its morbidity and mortality rates are around 40-60% due to its innate and acquired resistance to ... -
Chromatin remodeling protein Abf1 regulates expression of adhesin encoding genes in Candida glabrata
(2024-07)"The DNA spatial arrangement inside the nucleus critically depends on external stimuli and plays a fundamental role in gene expression. In the fungal opportunistic pathogen Candida glabrata (Nakaseomyces glabrata), gene ... -
CHARACTERIZATION OF THE RESPONSE OF Candida glabrata (Nakaseomyces glabratus) CLINICAL ISOLATES TO NEUTROPHILS
(2024-07-14)"Las infecciones por patógenos fúngicos están aumentando debido al incremento de la población inmunocomprometida. Algunos de los patógenos fúngicos más comunes del género Candida adquieren resistencia a los antifúngicos ... -
Microevolution of Candida glabrata in the presence of fluconazole
(2024-06)"Debido a la resistencia a los antifúngicos, las infecciones oportunistas causadas por C. glabrata representan riesgos para individuos inmunocomprometidos. Este estudio investiga el papel de la función mitocondrial y la ... -
Síntesis y caracterización de cerámicas de ultra alta temperatura mediante un enfoque innovador de molienda mecánica y sinterización por descarga de plasma a baja temperatura
(2024-06)"En el presente estudio, se investigaron dos cerámicas de ultra alta temperatura: TaC-WC y Ta-Re-B-WC. Ambas fueron sintetizadas por molienda mecánica y consolidadas mediante sinterización por descarga de plasma. La síntesis ... -

(2024-06)"El Estudio de las fallas activas al norte del municipio de San Luis Potosí, mediante técnicas de fotogrametría y métodos de tomografía eléctrica se realizó con el objetivo de comprender el origen de las discontinuidades ... -
Identificación en Lazo Cerrado de una Clase de Sistemas con Retardo Incierto en la Entrada
(2024)"En este trabajo de tesis se propone un esquema de control diseñado para una clase de sistemas lineales con retardo pequeño e incierto en la entrada. En particular, se combina un algoritmo de identificacion de retardo con ... -
Central Limit Theorem for a Class of Contractive Random Dynamical Systems and Critical Behavior in Connected Dynamical Systems
(2024)"In this thesis we use the spectral method to prove a Central Limit Theorem (CLT) for a class of contractive random dynamical systems. In this method, we start from the existence of a complex normed space in which the ... -
Anammox with alternative electron acceptors: perspectives for nitrogen removal from wastewaters
(Springer Nature, 2023)In the context of the anaerobic ammonium oxidation process (anammox), great scientific advances have been made over the past two decades, making anammox a consolidated technology widely used worldwide for nitrogen removal ... -
Dynamics of short-term ecosystem carbon fluxes induced by precipitation events in a semiarid grassland
(European Geosciences Union, 2023)Infrequent and small precipitation (PPT) events characterize PPT patterns in semiarid grasslands; however, plants and soil microorganisms are adapted to use the unpredictable small pulses of water. Several studies have ... -
Diversity and neocolonialism in Big Data research: Avoiding extractivism while struggling with paternalism
(SAGE, 2023)The extractive logic of Big Data-driven technology and knowledge production has raised serious concerns. While most criticism initially focused on the impacts on Western societies, attention is now increasingly turning to ... -
Simultaneous nitrification and autotrophic denitrification in fluidized bed reactors using pyrite and elemental sulfur as electron donors
(Elsevier, 2023)In this study, simultaneous nitrification and autotrophic denitrification (SNAD) with either elemental sulfur or pyrite were investigated in fluidized bed reactors in mesophilic conditions. The reactor performance was ... -
Extension of LoRa Coverage and Integration of an Unsupervised Anomaly Detection Algorithm in an IoT Water Quality Monitoring System
