La profesionalización docente en la modalidad online y la implementación de los REI: aciertos y desafíos
La profesionalización docente en la modalidad online se ha venido conformando como una oportunidad de formación para los profesores de matemáticas en servicio. El Programa de Matemática Educativa del Instituto Politécnico ...
A novel test procedure for evaluating the performance of composite cured-in-place-pipe liners in water pressure pipe rehabilitation
The cured-in-place pipe (CIPP) is a pipe rehabilitation technique that is becoming increasingly popular due to its cost advantages, reduced environmental impact, and decreased time requirements compared to traditional pipe ...
Novel Starch-Modified NiCrMn-LDH-Based Composite for Photocatalytic Degradation of Reactive Orange 13
Water pollution has become a great challenge today. To address this problem regarding wastewater treatment by removing toxic synthetic dyes from wastewater, this research focused on the synthesis of a novel starch-modified ...
Shear wave cardiovascular MR elastography using intrinsic cardiac motion for transducer-free non-invasive evaluation of myocardial shear wave velocity
Changes in myocardial stiffness may represent a valuable biomarker for early tissue injury or adverse remodeling. In this study, we developed and validated a novel transducer-free magnetic resonance elastography (MRE) ...
Hepatic overexpression of protein targeting to glycogen attenuates obesity and improves hyperglycemia in db/db mice
Increased liver glycogen content has been shown to reduce food intake, attenuate obesity, and improve glucose tolerance in a mouse model of high-fat diet (HFD)-induced obesity. Here we studied the contribution of liver ...
La llavor del Papa Francesc: Aparecida (Brasil), 2007
Analitzar el document final de la V Conferència General de l’Episcopat Llatinoamericà i del Carib, celebrada a Aparecida, Brasil, fa deu anys, el 2007, resulta avui especialment interessant, ja que el redactor principal ...
Ag(I) ions working as a hole-transfer mediator in photoelectrocatalytic water oxidation on WO3 film
Ag(I) is commonly employed as an electron scavenger to promote water oxidation. In addition to its straightforward role as an electron acceptor, Ag(I) can also capture holes to generate the high-valent silver species. ...
Las predicciones científicas de D.I. Mendeleiev
Este trabajo estudia las predicciones de Mendeleiev sobrela posible equivalencia entre materia y energía. Al mis-mo tiempo hace una crítica de algunos comentarios sobreeste punto aparecidos en la bibliografía. Pretende ser ...
Job prospects and labour mobility in China
China's structural changes have brought new challenges to its regional employment structures, entailing labour redistribution. Until now, Chinese migration research with a forward-looking perspective and on bilateral ...
The Ignatian Way: Transforming people and communities
The Ignatian Way (IW) is a pilgrimage route that Saint Ignatius of Loyola took in 1522, which goes through five different Autonomous Communities in the north of Spain, starting in the Basque Country location of Loyola, ...
The first look: a biometric analysis of emotion recognition using key facial features
Introduction: Facial expressions play a crucial role in human emotion recognition and social interaction. Prior research has highlighted the significance of the eyes and mouth in identifying emotions; however, limited ...
The virtuous cycle of trust. Unveiling clues to successful innovation in the Fast Moving Consumer Goods industry
Purpose: This paper aims to shed light on features of successful innovation and on the role played by downstream open innovation (OI) dynamics in the Fast Moving Consumer Goods (FMCG) industry. It also explores the reasons ...
Inquiry based mathematics education and the development of learning trajectories
This article is based on the panel on inquiry based mathematics education and the development of learning trajectories held at the VARGA 100 Conference. After an introduction presenting the theme and organization of the ...
Generador de funciones periódicas con controlador lógico-programable (PLC)
El análisis frecuencial de sistemas de control se basa en el conjunto de respuestas del proceso a señales senoidales que, en la mayoría de casos de los procesos habituales en la industria química, han de ser de muy baja ...
Entrapped Transient Chloroform Solvates of Bilastine
The knowledge about the solid forms landscape of Bilastine (BL) has been extended. The crystal structures of two anhydrous forms have been determined, and the relative thermodynamic stability among the three known anhydrous ...
A consistent thermodynamic molecular model of n-hydrofluoroolefins and blends for refrigeration applications
This work presents a thermodynamic model that characterizes 4th-generation hydrofluoroolefins (HFOs)-based refrigerants with the molecular-based soft-SAFT equation of state (Blas and Vega, 1998) as well as its application ...
Model food soils for investigating cleaning: A review
Cleaning operations are performed regularly throughout the food industry. This review focuses on the removal of strongly adherent fouling deposits which compromise the performance and hygienic status of equipment and ...
Parcours d’étude et de recherche: une étude sur les chemins minimaux
Cette étude vise à exposer le progrès d'un projet de recherche doctorale dont l'objectif est d'analyser les limites et les possibilités d'un parcours d'étude et de recherche (PER) en tant que stratégie didactique pour faire ...
Disseny de reactors fotoquímics: descripció dels models d’emissió de llum per a reactors anulars. Part 1, models clàssics
El disseny d’un reactor químic ha de contemplar normalment, a no ser que puguin simplificar-se, una sèrie de balanços: el de matèria, el d’energia i el de quantitat de moviment. A més d’aquests, un model de reactor fotoquímic ...
Neuronal Prosurvival Role of Ceramide Synthase 2 by Olidogendrocyte-to-Neuron Extracellular Vesicle Transfer
Ageing is associated with notorious alterations in neurons, i.e., in gene expression, mitochondrial function, membrane degradation or intercellular communication. However, neurons live for the entire lifespan of the ...
