New opportunities and perspectives of high pressure treatment to improve health and safety attributes of foods. A review
2015
Abstract High pressure (HP) treatment has emerged as a novel, additive-free food preservation technology. It has been scientifically and commercially proven that HP can produce microbially safe and stable products with improved quality characteristics such as enhanced flavor and color. Recent studies have focused on the effects of HP on health attributes and allergenic potential of foodstuff to develop the next generation of convenience foods. This review provides an overview on the current knowledge of HP treatment to improve the extraction and bioavailability of bioactive compounds, to reduce allergenicity, to retain essential fatty acids, to reduce the salt content, and to reduce formati…
Europeanised identifications among football fans. The analysis of discussions in online message boards.
2021
International audience; Across Europe, national professional football leagues have seen increasing numbers of players from other EU states, while the Champions League and the Europa League have become a focal point for many teams. This article seeks to investigate how far this Europeanisation on the organisational level of football is reflected in identities and discourses of fans. We develop a framework to analyse Europeanisation of identities among football fans. In the empirical part we conduct a qualitative content analysis of fan discussions on publicly available message boards among fans of four first league teams in England and Austria. Our empirical findings indicate that fans’ iden…
Stellar populations of galaxies in the ALHAMBRA survey up toz ∼ 1
2018
Aims. We aim at constraining the stellar population properties of quiescent galaxies. These properties reveal how these galaxies evolved and assembled since z similar to 1 up to the present time. Methods. Combining the ALHAMBRA multi-filter photo-spectra with the fitting code for spectral energy distribution MUFFIT (MUlti-Filter FITting), we built a complete catalogue of quiescent galaxies via the dust-corrected stellar mass vs. colour diagram. This catalogue includes stellar population properties, such as age, metallicity, extinction, stellar mass, and photometric redshift, retrieved from the analysis of composited populations based on two independent sets of simple stellar population (SSP…
Diseño y validación de un cuestionario sobre fracaso escolar en alumnado de educación secundaria
2013
Resumen: El presente artículo expone los resultados del diseño y la validación de un cuestionario sobre fracaso escolar, dirigido al alumnado de Educación Secundaria. Se trabajó con una muestra de 200 estudiantes en el Centro de F.P.A (Formación de Personas Adultas) Germà Colón de Castelló de la Plana (España) durante el curso 2010/2011. El instrumento está compuesto por 35 ítems, divididos en cuatro dimensiones principales (centro educativo, aula, profesorado y situación personal y familiar). Se desarrolla la validación de contenido mediante un Comité de Expertos, el análisis factorial para validar el constructo y el análisis de fiabilidad del cuestionario. Los resultados muestran una buen…
Chemical Characteristics and Viability of Starter Cultures of Freeze–Dried Sweet Potato Extract–Supplemented Synbiotic Yogurt
2021
The research aimed to determine the sucrose concentration as a cryoprotectant to obtain the chemical properties and the viability of Lactic Acid Bacteria (LAB) and Lactobasillus plantarum in the synbiotic yogurt. It adopted a one–factor Completely Randomized Design (CRD) by including sucrose in concentrations from 0 %, 2.5 %, 5 % to 7.5 %, three replications. The results showed various sucrose concentrations significantly affected the yields of the purple sweet potato extract– supplemented synbiotic yogurt, reduction–sugar level, the total of LAB, and the total of L. plantarum before and after the freeze–drying process, no significant impact on the moisture content and total quantity of LAB…
Validation and application of a PCR primer set to quantify fungal communities in the soil environment by real-time quantitative PCR
2011
Fungi constitute an important group in soil biological diversity and functioning. However, characterization and knowledge of fungal communities is hampered because few primer sets are available to quantify fungal abundance by real-time quantitative PCR (real-time Q-PCR). The aim in this study was to quantify fungal abundance in soils by incorporating, into a real-time Q-PCR using the SYBRGreen (R) method, a primer set already used to study the genetic structure of soil fungal communities. To satisfy the real-time Q-PCR requirements to enhance the accuracy and reproducibility of the detection technique, this study focused on the 18S rRNA gene conserved regions. These regions are little affec…
The adsorption of water vapor on super absorbent product at low temperatures and low mass.
2006
The adsorption isotherms of water vapor on super absorbent product have the same form of type III isotherm at ambient temperature with the hysteresis phenomena. For temperatures lower than ambient, the isotherms become deformed because of the chains effect. The polymer is characterized by a multilayer adsorption, which occurs before a full-course is complete. During adsorption reactions, the polymer undergoes rearrangement polymeric network, which results from a cooperative diffusion of the water molecules and from a chain spacing followed by an expansion of the polymeric network. Three types of water molecules adsorbed on polymer were identified: strongly dependent water, adsorbed water, a…
Weininger’s Influences in Wittgenstein’s Conception of Judaism
2016
El objetivo de este trabajo es contribuir a dilucidar la concepción wittgensteiniana del judaísmo. En general se admite que la obra de Otto Weininger influyó en el pensamiento de Wittgenstein, pero no hay acuerdo sobre el contenido de esa influencia. Aquí sostenemos que esta es perceptible, no solo en la concepción wittgensteiniana de la ética, la genialidad, el talento, etc., sino también en su caracterización del judaísmo y en el uso que el filósofo hace de esta idea. The aim of this work is to contribute to elucidate Wittgenstein’s conception of Judaism. It is generally acknowledged that Otto Weininger’s work influenced the thought of Wittgenstein, but there is no agreement on the conten…
The effects of post-pasture woody plant colonization on soil and aboveground litter carbon and nitrogen along a bioclimatic transect.
2013
Abstract: We investigated the effects of woody plant colonization of abandoned pastures on soil and litter organic carbon (C) stocks and nitrogen (N) content along a bioclimatic transect in a semi-arid environment (Sicily, Italy). Soil samples were taken in three successional stages (grazed pasture, shrubland, forest) within each of three bioclimates (supramediterranean - “supra”, mesomediterranean - “meso”, thermomediterranean - “thermo”). Organic C and N in litter and soil (0-10 cm and 10-30 cm depth) were determined, as well as soil bulk density. Especially at 0-10 cm depth, changes in C and N contents along successional stages differed among bioclimates. Soil organic carbon (SOC) stock …
Variation characteristics of soil respiration fluxes in four types of grassland communities under different precipitation intensity
2005
A two consecutive years’ field experiment was carried out on four types of semiarid grassland along precipitation gradient in Xilin River Basin of Inner Mongolia during 2001–2003 using a static enclosed black chamber technique. The variation characteristics of soil respiration fluxes from four different types of grassland along precipitation gradient were compared. The possible effect of water-heat factors on characteristics of grassland soil respiration was statistically analyzed and the numerical relational model between soil respiration and water-heat factors was established. Meanwhile the soil CO2 annual emissions of different types of grassland were estimated based on the consecutive a…
