Diffusion of oxygen in cork.
2012
International audience; This work reports measurements of effective oxygen diffusion coefficient in raw cork. Kinetics of oxygen transfer through cork is studied at 298 K thanks to a homemade manometric device composed of two gas compartments separated by a cork wafer sample. The first compartment contains oxygen, whereas the second one is kept under dynamic vacuum. The pressure decrease in the first compartment is recorded as a function of time. The effective diffusion coefficient D-eff is obtained by applying Fick's law to transient state using a numerical method based on finite differences. An analytical model derived from Fick's law applied to steady state is also proposed. Results give…
Inductive Power Transfer for 100W battery charging
2013
Today, Inductive Power Transfer (IPT) is widely investigated to provide wireless battery charge. Potential applications range from a few Watts of handheld devices to kWatts of automotive applications. Despite of comfort and safety options, wireless charging features relatively poor power conversion efficiency. In the literature, several solutions are proposed addressing efficiency related issues. In this paper, a 100W wireless charging station for electric bikes which improves the power conversion efficiency is proposed. The magnetic structure design is analyzed thoroughly as well as the proposed power electronics system architectures of both the power transmitter and power receiver. The ef…
List do Rzymian w „Katechezach” Cyryla Jerozolimskiego. Sposoby wykorzystania i interpretacji
2018
Cyril of Jerusalem, the author of the Catechesis delivered to the catechumens and the newly baptized, gave the teachings of Jesus Christ on the basis of the Symbol in force in Jerusalem, and above all on the basis of the Holy Scriptures. He readily referred to the books of the Old and New Testaments, quoting literal citations or paraphrasing individual biblical ideas. Among the frequently quoted biblical books is also the St. Paul’s Epistle to the Romans, which was used by Cyril almost 40 times. Some of Paul’s statements were used as an element of the content link, while others are the starting point for presenting the wider context of Christian teachings to the audience. In most cases, the…
La cúpula de la Basílica de la Virgen de los Desamparados de Valencia (I): el ámbito de la gloria
2007
-Rafael.G-Mahiques@uv.es Estudio iconográfico de los frescos de la cúpula de la Basílica de la Virgen de los Desamparados de Valencia, obra de Antonio Palomino realizada entre 1701 y 1704. Aproximación a un análisis del ámbito de la Gloria celestial. Aquí la Virgen aparece como reina e intercesora ante el Trono de Gracia, en donde, de acuerdo con la tradición iconográfica, se incluye a San Juan Bautista y los arma Christi portados por ángeles. En torno a este núcleo se disponen los bienaventurados, agrupados bajo el criterio de la Letanía Lauretana, en la cual María es invocada con los títulos de Reina de los Ángeles, de los Patriarcas, Profetas, Apóstoles, Mártires, Confesores, Vírgenes y …
Life-history trade-offs in a generalist digenean from cetaceans: the role of host specificity and environmental factors
2015
Background Adults and larvae of generalist parasites are exposed to diverse hosts and local environmental conditions throughout their life cycles, thus local adaptation is expected to occur through phenotypic plasticity and/or natural selection. We investigated how the combined effect of cryptic host specificity and local selective pressures could shape reproductive traits of a putative generalist parasite in the oceanic realm. Methods The LSU rDNA, ITS2 and the mt-COI of individuals of the digenean Pholeter gastrophilus (Kossack, 1910) Odhner, 1914 (Heterophyidae Leiper, 1909) from oceanic striped dolphins, Stenella coeruleoalba Meyen, and coastal bottlenose dolphins, Tursiops truncatus Mo…
Regional variations in the chemical and helium–carbon isotope composition of geothermal fluids across Tunisia
2011
Abstract Tunisia has numerous thermo-mineral springs. Previous studies have shown that their chemical composition and occurrence are strongly influenced by the regional geology. However little work has been done so far to study the isotopic composition of volatiles associated with these geothermal manifestations. Here, we report on the results of an extensive survey of both natural hot springs and production wells across Tunisia, aimed at investigating the spatial distribution of thermal fluids' geochemical characteristics and He–C isotopic composition. The chemistry of the analyzed samples highlights the heterogeneity of the water mineralization processes in Tunisia, as a consequence of th…
Bene vivere politice
2022
Abstract This chapter approaches the question of biopolitics in ancient political thought looking not at specific political techniques but at notions of the final aim of the political community. It argues that the “happiness” (eudaimonia, beatitudo) that constitutes the greatest human good in the tradition from Aristotle to Thomas Aquinas is not a “biopolitical” ideal, but rather a metabiopolitical one, consisting in a contemplative activity situated above and beyond the biological and the political. It is only with Thomas Hobbes that civic happiness becomes “biopolitically” identified with simple survival; for modernity, as Hannah Arendt puts it, mere being alive becomes the greatest human…
Il turismo nelle/delle destinazioni
2015
L’importanza territoriale, economica e socio-culturale del settore turistico è tale da richiedere continui approfondimenti teorici che s’originano dal monitoraggio delle nuove forme di offerta e dei loro effetti sui contesti locali. I saggi di questo volume seguono, in chiave diacronica, il discorso iniziato con la pubblicazione, per i tipi dell’Editore Pàtron, dei volumi “Scritture di Paesaggio” (2003), “Luoghi e turismo culturale” (2006) e “Spazi contesi spazi condivisi. Geografie dell’interculturalità” (2010).
Transnationalism and Settlement of Latvian Emigrants in the Nordic Countries
2021
The intra-European migration flows have fostered debates about the intentions of migrants to settle in their destination country or return to their countries of origin. Based on a quantitative analysis of survey data ('N' = 1391), this article presents a typology of migration patterns among migrants from Latvia in the Nordic countries. Using two dimensions—attachment to the destination country and attachment to the country of origin—the article identifies and characterises the following four migration patterns: (1) bi-nationals, (2) settlers, (3) footloose migrants and (4) isolated migrants who focus on their country of origin and are willing to return (separated).
Functional coupling of nitric oxide synthase and soluble guanylyl cyclase in controlling catecholamine secretion from bovine chromaffin cells
1997
This study was designed to evaluate whether the enzymes of the nitric oxide/cyclic-GMP pathway, nitric oxide synthase and soluble guanylyl cyclase, are functionally coupled in controlling catecholamine secretion in primary cultures of bovine chromaffin cells. In immunocytochemical studies, 80-85% of the tyrosine hydroxylase-positive chromaffin cells also possessed phenylethanolamine-N-methyltransferase, f1p4cating their capability to synthesize epinephrine. Immunoreactivity for neuronal-type nitric oxide synthase was found in over 90% of all chromaffin cells. Reverse transcription-polymerase chain reaction also demonstrated neuronal-type nitric oxide synthase messenger RNA. Immunoreactivity…
