Moviments de dispersió en els primats. Variabilitat en els seus patrons i causes
2014
Els moviments de dispersió en els animals representen decisions crucials per als individus, ja que afecten la seua supervivència i èxit reproductiu, a més de ser un component important de la dinàmica poblacional. En aquest article es descriu la variabilitat en els patrons de dispersió en els primats i algunes de les causes, tant últimes com proximals, a les quals respon.
Effects of NH3 and alkaline metals on the formation of particulate sulfate and nitrate in wintertime Beijing
2020
Sulfate and nitrate from secondary reactions remain as the most abundant inorganic species in atmospheric particle matter (PM). Their formation is initiated by oxidation (either in gas phase or particle phase), followed by neutralization reaction primarily by NH3, or by other alkaline species such as alkaline metal ions if available. The different roles of NH3 and metal ions in neutralizing H2SO4 or HNO3, however, are seldom investigated. Here we conducted semi-continuous measurements of SO4 2−, NO3 −, NH4 +, and their gaseous precursors, as well as alkaline metal ions (Na+, K+, Ca2+, and Mg2+) in wintertime Beijing. Analysis of aerosol acidity (estimated from a thermodynamic model) indicat…
The iron-regulatory hormone hepcidin: A possible therapeutic target?
2015
The maintenance of stable extracellular and intracellular iron concentrations requires the coordinated regulation of iron transport into plasma. Iron is a fundamental cofactor for several enzymes involved in oxidation-reduction reactions. The redox ability of iron can lead to the production of oxygen free radicals, which can damage various cellular components. Therefore, the appropriate regulation of systemic iron homeostasis is decisive in vital processes. Hepcidin has emerged as the central regulatory molecule of systemic iron homeostasis. It is synthesized in hepatocytes and in other cells and released into the circulation. It inhibits the release of iron from enterocytes of the duodenum…
Alcohol Abuse Mediates the Association between Baseline T/C Ratio and Anger Expression in Intimate Partner Violence Perpetrators.
2015
The imbalance between testosterone (T) and cortisol (C) levels has been proposed as a possible marker of risk for intimate partner violence (IPV). Moreover, it could be related to a high probability of adopting risky behaviors such as alcohol abuse which, in turn, promotes the onset of IPV. This study tested the potential mediating effect of alcohol consumption on the relationship between baseline T/C ratio and anger expression in IPV perpetrators and non-violent controls. Alcohol consumption was higher in the former than controls. A high baseline T/C ratio was only associated with high anger expression in IPV perpetrators, and this association was mediated by high alcohol consumption. Thus…

Involucri Traslucidi in Vetromattone: nuove tecniche di assemblaggio a secco ed incremento prestazionale del prodotto per la riduzione del valore di …
2010
Nel corso del Novecento l’impiego dei diffusori di vetro per la realizzazione di elementi tecnici traslucidi in grado di captare la luce naturale ha subito alterne vicende. Dopo un periodo di intenso utilizzo a cavallo del XIX e XX secolo e dopo la realizzazione, in Europa, negli anni a cavallo tra le due guerre, di alcuni edifici divenuti emblematici del Movimento Moderno, l’impiego di questo prodotto “innovativo” per l’epoca, venne progressivamente “relegato” alle parti più nascoste degli edifici per la “pragmatica” risoluzione di problematiche legate, ad es., alla presenza di particolari vincoli urbanistici senza che, quindi, ne venissero ulteriormente indagate le potenzialità espressive…
MIGLIORAMENTO TECNOLOGICO-PRESTAZIONALE DI UN COMPONENTE INNOVATIVO PER L’INVOLUCRO EDILIZIO - PERFOMANCE IMPROVEMENT OF AN INNOVATIVE BUILDING COMPO…
2016
L’articolo illustra l’attività di ricerca che gli autori, cofounder della SBskin. Smart Building Skin s.r.l., start up innovativa e spin off accademico dell’Università degli Studi di Palermo, stanno conducendo al fine di ottimizzare le performance energetiche di un componente innovativo per facciate e coperture di edifici (dagli stessi brevettato) in grado di ridurre i consumi energetici e di produrre energia pulita dal sole. L’attività che qui si illustra è stata finalizzata all’ottimizzazione del design dei sub-componenti che contribuiscono alla realizzazione dei pannelli traslucidi multifunzionali (realizzati con vetromattoni innovativi, preassemblati a secco e precompressi) ed alla scel…
Nuevas perspectivas de análisis para entender la migración cualificada del sur de Europa hacia México
2018
This article focuses on skilled migration flows from Southern Europe into Mexico. From semi-structured interviews with Spanish and Italian immigrants living in four Mexican cities of Mexico, it addresses both reasons for immigration and labour incorporation in Mexican labour markets. Specifically, it explores: i) the role of the economic crisis and the lack of good employment in the countries of origin as a key factor when deciding an international migration; ii) the employment opportunities offered in Mexican labour markets for the highly-skilled immigrants, and iii) the role played by the Mexican state and its current immigration law when channelling this group into the labour market
La ambigua institucionalización de la eutanasia como derecho individual de carácter prestacional. Apunte crítico sobre la lo 3/2021, de 24 de marzo
2021
Se abordan aquí tres aspectos relativos a la Ley española de eutanasia, promulgada el 24 de marzo de 2021, que resultan especialmente problemáticos: la falsa configuración de la eutanasia como un ?derecho subjetivo?, el falso protagonismo de la autonomía del sujeto y la calificación de la eutanasia como ?muerte natural?. Se sostiene la tesis de que la ley solo ha despenalizado el delito eutanásico cuando se realiza de acuerdo con los requisitos legales; de que no existe un derecho a la muerte y por tanto no es la voluntad del solicitante la que determina la prestación eutanásica y las repercusiones que se producirán en diversos ámbitos por la calificación de muerte natural.
