Recent Developments in Understanding Biochar’s Physical–Chemistry
2021
Biochar is a porous material obtained by biomass thermal degradation in oxygen-starved conditions. It is nowadays applied in many fields. For instance, it is used to synthesize new materials for environmental remediation, catalysis, animal feeding, adsorbent for smells, etc. In the last decades, biochar has been applied also to soils due to its beneficial effects on soil structure, pH, soil organic carbon content, and stability, and, therefore, soil fertility. In addition, this carbonaceous material shows high chemical stability. Once applied to soil it maintains its nature for centuries. Consequently, it can be considered a sink to store atmospheric carbon dioxide in soils, thereby mitigat…
Seneca on the Nature of Things: Moral Concerns and Theories of Matter in Natural Questions 6
2017
It is generally recognized that Lucretius' treatment of earthquakes and pestilences (6.535-607; 1090-1286) exerted great influence on Book 6 of Seneca's Natural Questions. But while a large consensus exists that both authors tend to emphasize the moral value of scientific knowledge, further research is needed with respect to Seneca's “technical” re-use of Epicurean physics and meteorology. In the present paper, I shall address this issue in three stages. First, I will analyze the structure and intellectual goals of Seneca's “doxographic” review of seismological theories (6.5-20). Far from being a doxographic account sensu proprio, such a careful review constructs the inspiring image of an i…
Leisure time physical activity is associated with improved HDL functionality in high cardiovascular risk individuals: a cohort study.
2020
Abstract Aims Physical activity has consistently been shown to improve cardiovascular health and high-density lipoprotein-cholesterol levels. However, only small and heterogeneous studies have investigated the effect of exercise on high-density lipoprotein functions. Our aim is to evaluate, in the largest observational study to date, the association between leisure time physical activity and a range of high-density lipoprotein functional traits. Methods The study sample consisted of 296 Spanish adults at high cardiovascular risk. Usual leisure time physical activity and eight measures of high-density lipoprotein functionality were averaged over two measurements, one year apart. Multivariabl…
Valutazioni interscalari nel processo perequativo del PRG di Siracusa
2016
La questione abitativa è tornata ad essere cruciale per assicurare una maggiore equità sociale, aumentando la coesione sociale e riducendo le diseguaglianze all’interno dei sistemi metropolitani o territoriali che, nell’attuale congiuntura di grave crisi economica, devono comunque rispondere alle sfide globali di sviluppo, innovazione e sostenibilità. Questo studio si propone di costruire un sistema di conoscenze sulle condizioni di accesso alla casa a scala territoriale attraverso cui individuare le criticità locali dei problemi abitativi che potrebbero essere risolti attraverso i tradizionali strumenti di pianificazione o attraverso nuove pratiche di Social Housing che coinvolgono soggett…
Questionnaires and simulations to assess daylighting in Italian university classrooms for IEQ and energy issues
2021
Abstract Results from the DAYKE-Italy project are presented. An investigation on daylighting in eight classrooms in five Italian universities was carried out through a combined approach: an ad-hoc survey administered to students to investigate how they perceive daylight in classroom, and numerical simulations (DIVA + ALFA) to calculate a set of objective metrics (daylight, circadian, and energy-related). A sample of 542 questionnaires was collected through two sessions and the subjective judgments were correlated to objective metrics. Results from descriptive and statistical analyses showed: (i) the correlation was significant for all daylight metrics: among them, average daylight factor an…
Life satisfaction in university students with disabilities: Differences by sociodemographic variables and associations with physical activity and ath…
2022
People with disabilities tend to have lower subjective well-being than their peers without disability. This study examined differences in the life satisfaction (LS) of Spanish university students with disabilities according to sociodemographic variables, and its associations with physical activity (PA) and athletic identity (AI). A crosssectional study was conducted with 1,227 participants (624 Female - 598 Male) from state and private Spanish universities. The participants completed an electronic survey on LS, PA and AI after which a descriptive analysis, pairwise comparisons (Mann-Whitney U, Kruskal-Wallis tests), and Spearman's correlations were performed on the data. Instruments used fo…
Aproximación al arte de la platería española
2008
[EN]: This article originated in a lecture given in the Department of Art History, University of Valencia. An attempt was made to offer an overview of Spanish silverwork. For this reason the focus was placed on the state of the question in order to determine the situation of research in Spain. Special focus was given to the new lines of study being opened, which place silverwork studies at the forefront of Spanish art historical studies.
Innovations in medical care and mortality trends from four circulatory diseases between 1970 and 2005
2013
Background: Governments have identified innovation in pharmaceuticals and medical technology as a priority for health policy. Although the contribution of medical care to health has been studied extensively in clinical settings, much less is known about its contribution to population health. We examine how innovations in the management of four circulatory disorders have influenced trends in cause-specific mortality at the population level. Methods: Based on literature reviews, we selected six medical innovations with proven effectiveness against hypertension, ischaemic heart disease, heart failure and cerebrovascular disease. We combined data on the timing of these innovations and cause-spe…

P-76D-PENICILLAMINE, AN ACETALDEHYDE SEQUESTERING AGENT, REDUCES ETHANOL PREFERENCE IN ALCOHOL-NAÏVE RATS
2015
In previous investigations, we demonstrated that D-penicillamine (DP), a sulfhydryl aminoacid which has been studied as sequestration agent of acetaldehyde (ACD), is able to prevent the alcohol deprivation effect (ADE) but not voluntary ethanol consumption. Both results were obtained in long-term ethanol-experienced Wistar rats. Based on a previous …
