L'origine della poesia bucolica in Grecia

2007

Aportaciones de la herpetofauna al conocimiento de la paleobiología y paleoclimatología del tramo temporal Pleistoceno Superior y Holoceno de la Comu…

2022

El periodo Cuaternario se caracteriza climáticamente por la alternancia de fases glaciales e interglaciales, y, asociadas a ellas, importantes fluctuaciones de la línea de costa. Dado que este marco temporal es altamente relevante en el campo de la evolución humana y, por ello, gran parte de su estudio se ha centrado en esta temática; también lo es para entender diversos aspectos de la historia natural de otros grupos de vertebrados, como es el caso de los reptiles y anfibios. Hasta ahora son escasos los estudios del componente herpetológico de las faunas de vertebrados en el este de la península ibérica durante el Pleistoceno Superior y Holoceno, habiéndose centrado fundamentalmente este e…

Lentil Fortified Spaghetti: Technological Properties and Nutritional Characterization

2021

Lentil (Lens culinaris), consumed as a part of the diet worldwide, is a functional dietary ingredient that plays a function in human nutrition as a rich source of bioactive nutrients (low quantities of fat, sodium, and vitamin K

Effect of Adding Resistant Maltodextrin to Pasteurized Orange Juice on Bioactive Compounds and Their Bioaccessibility

2021

Resistant maltodextrin (RMD) is a water-soluble and fermentable functional fiber. RMD is a satiating prebiotic, reducer of glucose and triglycerides in the blood, and promoter of good gut health, and its addition to food is increasingly frequent. Therefore, it is necessary to study its potential effects on intrinsic bioactive compounds of food and their bioaccessibility. The aim of this study was to evaluate the effect of adding RMD on the bioactive compounds of pasteurized orange juice with and without pulp, and the bioaccessibility of such compounds. RMD was added at different concentrations: 0 (control sample), 2.5%, 5%, and 7.5%. Ascorbic acid (AA) and vitamin C were analyzed using HPLC…

Virtual Tours as Emerging Technologies to Engage Children and Youth with their Country’s Historical Conflicts

2022

Virtual Reality (VR) is increasingly used for visiting historic places. Research on VR experiences in dark tourism (that focuses on mortality) focuses almost exclusively on adults. No studies were found that used virtual tours to engage children with their own country’s conflicts. The present study addresses this gap by designing and developing virtual tours in four cities of Europe with a troubled past. Virtual tours engage children and youth in historical conflicts using multi-perspective storytelling. The aim of this pre-test post-test comparative case study is to examine the change on students’ perceptions of their country’s troubled past after their interaction with a virtual tour of t…

L’Astrée. Troisième partie

2022

Un siècle après l’Arcadia de Sannazar (1504), L’Astrée marque l’achèvement de la conquête de l’antique fable pastorale par les littératures européennes en langues vulgaires : paru entre 1607 et 1628, le roman d’Honoré d’Urfé est le dernier des grands chefs-d’œuvre nourris de la veine des histoires de bergers. Mais la narration des amours d’Astrée et Céladon dans la Gaule du Ve siècle inaugure aussi une nouvelle époque de la littérature française. Premier des grands récits publiés au moment où la France répare les plaies nées des guerres de Religion, l’œuvre est très vite apparue comme une étape décisive dans l’art du roman, en même temps que, par sa philosophie de « l’honnête amitié », elle…

Bioaccessibility of tocopherols, carotenoids, and ascorbic acid from milk- and soy-based fruit beverages: Influence of food matrix and processing

2012

A study was made of the effect of high-pressure processing (HPP) and thermal treatment (TT) on plant bioactive compounds (tocopherols, carotenoids, and ascorbic acid) in 12 fruit juice-milk beverages and of how the food matrix [whole milk (JW), skimmed milk (JS), and soy milk (JSy)] modulates their bioaccessibility (%). HPP (400 MPa/40 °C/5 min) produced a significant decrease in carotenoid and ascorbic acid bioaccessibility in all three beverages and maintained the bioaccessibility of tocopherols in JW and JS while decreasing it in JSy. TT (90 °C/30 s) produced a significant decrease in tocopherol and carotenoid bioaccessibility in all three beverages and increased the bioaccessibility of …

Metallic lead recovery from lead-acid battery paste by urea acetate dissolution and cementation on iron

2009

Abstract A suitable hydrometallurgical and environmentally friendly process was studied to replace the currently used practices for recycling lead-acid batteries via smelting. Metallic lead was recovered by cementation from industrial lead sludge solutions of urea acetate (200 to 500 g/L) using different types of metallic iron substrates (nails, shaving or powder) as reducing agents. Under specific operating conditions, up to 99.7% of lead acid battery paste, mainly composed of PbSO4, PbO2 and PbO·PbSO4 species, was converted to metallic lead.. The conversion of the metallic lead and rate of the cementation reaction were strictly dependent on the type of iron substrate used as the reductant…

Toward a holistic understanding of pastoralism

2021

Pastoralism is globally significant in social, environmental, and economic terms. However, it experiences crises rooted in misconceptions and poor interdisciplinary understanding, while being largely overlooked in international sustainability forums and agendas. Here, we propose a transdisciplinary research approach to understand pastoralist transitions using (1) social, economic, and environmental dimensions, (2) diverse geographic contexts and scales to capture emerging properties, allowing for cross-system comparisons, and (3) timescales from the distant past to the present. We provide specific guidelines to develop indicators for this approach, within a social-ecological resilience anal…

La dimensione tecnologica del museo: forme, tecniche, "identità mutanti" tra storia e contemporaneità

2005

Nella cultura contemporanea il tema della conservazione dell’eredità storica, della rappresentazione e della trasmissibilità dell’arte è argomento ampiamente dibattuto. La forza culturale del museo, detentore dell’eredità, può essere interpretata secondo diverse traiettorie di forme. La memoria intende esprimersi sulle origini e sul significato della "macchina museale" attraverso l’analisi critica dell’oggetto, sia esso contenitore, palco di rappresentazione o scena interattiva. Sonda i processi di comunicazione relativamente alla forma architettonica, alla funzione ed alla fruizione del prodotto espositivo. Tenendo conto delle diverse scuole di pensiero sulla spettacolarizzazione dell’arte…
