Panorámica de la desigualdad digital en España: operacionalización y dimensionamiento de las brechas digitales de accesibilidad, habilidades y formas…
2019
En este artículo, se realiza un análisis estadístico de la desigualdad digital en España a partir de una operacionalización de las tres brechas digitales más relevantes: (1) accesibilidad a los dispositivos TIC; (2) competencias y habilidades digitales; y (3) prácticas digitales y formas diferenciales de uso. La metodología es cuantitativa, basada en la última oleada (2018) de la encuesta sobre equipamientos tecnológicos en el hogar del INE (TIC-H), a partir de la cual se ha desarrollado un análisis comparativo por género, edad, nivel de estudios, situación laboral y tipo de hábitat residencial. Los resultados muestran cómo la desigualdad de acceso tiene actualmente más que ver con las moda…
Consumo de alimentos funcionales: factores determinantes
2019
El concepto de alimento funcional nació en Japón en 1991, y desde entonces ha sido objeto de estudio debido al gran crecimiento de mercado que ha experimentado esta categoría de producto en las últimas décadas (Arai, Osawa, Ohigashi, Yoshikawa, Kaminogawa, Watanabe, . . . Nishino, 2001). En líneas generales, podemos definir que un alimento se considera funcional si se demuestra que ejerce un efecto beneficioso sobre una o más funciones selectivas del organismo, además de sus efectos nutritivos intrínsecos, de modo que mejore el estado de salud y bienestar, reduzca el riesgo de enfermedad, o ambas cosas (Diplock, Agget,Ashwell, Bornet, Fern y Roberfroid, 1999). Ahora bien, el consumidor s…
Influence of torrefaction pretreatment on the pyrolysis of Eucalyptus clone: A study on kinetics, reaction mechanism and heat flow
2016
Abstract The adverse nature of biomass requires specific pretreatment processes to better utilize it in bioenergy applications, and torrefaction is one of the most recognized thermal pretreatment methods. In this regard, we studied the effect of torrefaction pretreatment on kinetics, reaction mechanism and heat flow during the pyrolysis of biomass by making a comparative analysis between the pyrolysis of dried and torrefied Eucalyptus wood. Torrefied biomass was produced at three temperatures, namely 250, 275 and 300 °C. Pyrolysis was performed at 700 °C. The char yield during pyrolysis increased from 22.39 percent to 36.34 percent when the torrefaction temperature was increased from 250 to…
Recovering a variable exponent
2021
We consider an inverse problem of recovering the non-linearity in the one dimensional variable exponent $p(x)$-Laplace equation from the Dirichlet-to-Neumann map. The variable exponent can be recovered up to the natural obstruction of rearrangements. The main technique is using the properties of a moment problem after reducing the inverse problem to determining a function from its $L^p$-norms.
Rhabdomyosarcoma of the head and neck in pediatric patients: a systematic review.
2022
Rhabdomyosarcoma (RMS) is a soft tissue malignant tumor of mesenchymal cell origin, which usually shows variable differentiation of muscle cells. It is the most common solid sarcoma in children. The most usual site of occurrence are the head and neck regions. RMS presents a variety of histologic features, and so differential diagnosis with other small round cell tumors is needed. Hence, it has been very useful to the field to undertake additional immunohistochemical studies to determine the diagnosis and, on occasions, to assign subtype tumors. A systematic review of three databases (Medline, Biological Science Collection and Health & Medical Collection) was carried out with the purpose of …
Antitumor Cell-Complex Vaccines Employing Genetically Modified Tumor Cells and Fibroblasts
2014
The present study evaluates the immune response mediated by vaccination with cell complexes composed of irradiated B16 tumor cells and mouse fibroblasts genetically modified to produce GM-CSF. The animals were vaccinated with free B16 cells or cell complexes. We employed two gene plasmid constructions: one high producer (pMok) and a low producer (p2F). Tumor transplant was performed by injection of B16 tumor cells. Plasma levels of total IgG and its subtypes were measured by ELISA. Tumor volumes were measured and survival curves were obtained. The study resulted in a cell complex vaccine able to stimulate the immune system to produce specific anti-tumor membrane proteins (TMP) IgG. In the g…
Differences between current clinical guidelines for screening, diagnosis and management of non-alcoholic fatty liver disease and real-world practice:…
2021
International audience; INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease and is associated with obesity and metabolic comorbidities. Liver steatosis can progress to nonalcoholic steatohepatitis (NASH) exhibiting a relevant risk of fibrosis and ultimately liver failure. To date, no approved treatment for NASH to reduce its clinical and humanistic burden has been developed. AREAS COVERED: We undertook a literature review to identify English language, national and international clinical guidelines for NAFLD regarding diagnosis, assessment and management, and determined their points of agreement and difference. Additionally, we investigated published liter…
La classificació de la documentació parlamentària de les Corts Valencianes: la funció de control al Consell.
2008
El dinamisme necessari en una institució parlamentària com les Corts Valencianes requereix de l'organització del fons documental i, per tant, la necessitat d'elaborar un sistema de gestió documental integral. L'objectiu és facilitar la recuperació d'informació parlamentària per a la millora de la gestió, la presa de decisions, l'enriquiment dels debats i la investigació sobre la institució. L'accés a la documentació facilita també el coneixement de les funcions de la cambra, i l'aproximació dels ciutadans a les Corts. Això s'ha concretat en l'elaboració d'un quadre de classificació per a descriure el fons documental i gestionar-ne la recuperació, l'eliminació o la conservació. La metodologi…
