Operationalization of un-captured GDP - Innovation stream under new global mega-trends
2016
With the understanding that current ICT-driven global development depends on a trend shifting from traditional co-evolution of computer-initiated ICT, captured GDP, and economic functionality to new co-evolution of the Internet, un-captured GDP, and supra-functionality beyond economic value, the following hypothetical view was postulated: The disparity between the world's ICT leader countries with respect to happiness/welfare amidst great stagnation (Finland) or conspicuous economic growth (Singapore) can be attributed to the difference of the state in the above shifting trends. The foregoing hypothetical view was demonstrated on the basis of an empirical analysis measuring dependency on un…
Vitamin A deficiency causes oxidative damage to liver mitochondria in rats.
2000
Mitochondrial damage in rat liver induced by chronic vitamin A-deficiency was studied using three different groups of rats: (i) control rats, (ii) rats fed a vitamin A-free diet until 50 d after birth and (iii) vitamin A-deficient rats re-fed a control diet for 30 d. No statistical difference in body weight and food intake was found between control and vitamin A-deficient rats. Liver GSH concentration was similar in both groups. However, in vitamin A-deficient rats, the mitochondrial GSH/GSSG ratio was significantly lower and the levels of malondialdehyde (MDA) and 8-oxo-7, 8-dihydro-2'-deoxyguanosine (oxo8dG) were higher when compared to control rats. These values were partially restored i…
Heritage Destruction in Syria and Northern Iraq: Which is the Applicable Law?
2021
The paper aims at reconstructing the applicable legal framework to the widespread destruction of cultural heritage. At first, a legal classification of the conflict under international humanitarian law is provided, with the aim to identify the applicable law. In the second part of the paper, the problem of heritage destruction in Syria is dealt under a double perspective: (i) framing the obligations and potential responsibility fo States (the Syrian Arab Republic and eventually other foreign States involved in the hostilities); and (ii) individual criminal responsibility arising for the perpetrated acts of destruction of cultural heritage.
Intervención sindical y salud laboral en la Unión Europea: dimensiones, cobertura e impacto
2018
The determining factors of workers’ quality of employment and occupational health are many and different, including from those of a structural nature (productive sector, size of company, labour organization, type of contract) and contextual (economic cycle, normative regulation ), to those with an institutional dimension (system of labor relations, union participation, collective bargaining, Labor Inspection) and, even, cultural (business management model, preventive training programs and risk assessment). Regarding the influence of the first group of such factors (structural and contextual) on the evolution of occupational accidents, there is already important specialized literature and em…
EGUAGLIANZA E WELFARE DEGLI IMMIGRATI: TRA SELF-RESTRAINT LEGISLATIVO E APERTURE GIURISPRUDENZIALI E CONTRATTUALI
2018
Il saggio analizza la tutela previdenziale e assistenziale di cui godono gli immigrati regolarmente soggiornanti in Italia alla luce dell’ordinamento internazionale, di quello europeo, e dei princìpi costituzionali. Nonostante le fonti «multilivello» sanciscano una tendenziale parità di trattamento tra cives e non cives, le legislazioni statali e regionali restringono la platea dei migranti beneficiari delle prestazioni soprattutto assistenziali. Tale orientamento restrittivo è in parte controbilanciato, sia dalla giurisprudenza di merito e costituzionale alla luce dei princìpi di ragionevolezza e non discriminazione, sia dall’intervento della contrattazione collettiva. The present work ana…
Wine-making with protection of must against oxidation in a warm, semi-arid terroir
2016
In order to defend varietal aromas from oxidation before alcoholic fermentation, two musts were prepared from white grapes pre-cooled and added with ascorbic acid and solid CO2 (trial ACO2) or SO2 (trial BSO2). Experiments were performed with grapes of a white grape variety indigenous to western Sicily, the wines from which, obtained by vinification of musts protected from oxidation and poor in copper, as previously proven, have aroma descriptors ascribed to passion fruit and grapefruit skin. The smaller content in flavanols in the ACO2 trial, demonstrated that the use of solid CO2, instead of SO2, reduced the extraction of such polyphenols from grape solids. The higher content in hydroxyci…
Serveis i recursos socials per a dones: la resposta institucional de la Comunitat Valenciana
2014
This article summarises Valencia’s current institutional response for women, above all those suffering processes of social exclusion and violence. Some of the most important regional services and resources are the General Social Services (which include economic benefits such as emergency aid or the Guaranteed Citizens’ Income), services providing information and advice such as (the Infodona Centre or a hotline of legal advice for women) and specific resources and social services (+Life program, 24 Hour Women’s Centres and protection centres ranging from emergency shelters to sheltered housing). This article will provide relevant data on these services and resources obtained through reports …
Kerr self-cleaning of pulsed beam in an ytterbium doped multimode fiber
2017
International audience; We experimentally demonstrate that Kerr spatial self-cleaning of a pulsed beam can be obtained in an amplifying multimode optical fiber. An input peak power of 500 W only was sufficient to produce a quasi-single-mode emission from the double-clad ytterbium doped multimode fiber (YMMF) with non-parabolic refractive index profile. We compare the self-cleaning behavior observed in the same fiber with loss and with gain. Laser gain introduces new opportunities to achieve spatial self-cleaning of light in multimode fibers at a relatively low power threshold.
Study of the fuel/clad bonding of pressurized water reactors fuel rods
2017
Durability and integrity of materials used in nuclear power plants is a continuous concern of the nuclear power plant owners and developers. During the fuel irradiation in pressurised water reactors (PWR), the whole fuel-clad assembly is subjected to several irradiation-induced modifications. In particular, the fuel element expansion concomitant to the cladding creeping, leads to the contacting of both materials, allowing the oxidation of the inner side of the clad, locally at first, then tending to affect the overall cladding inner surface. At high burnup, a bonding of the fuel periphery with the metallic cladding can be observed, forming the fuel-clad bonding phenomenon, which conditions …
Physical, chemical and mechanical evolution of the fuel-cladding interface in irradiated PWR fuel rods
2022
During the fuel irradiation in nuclear reactor, the fuel-cladding assembly is exposed to several irradiation-induced modifications. The fuel swelling coupled with cladding creep leads to a contact between the fuel and the cladding. The oxygen transport from the UO2 fuel to the zirconium layer induces progressively the Zr-cladding oxidation. This oxidation is initially local with the formation of islets. Then, with the increasing burnup of the fuel, it conducts to a continuous layer of about 8-µm thickness, localized at the fuel-cladding interface. At high burnup, zirconia growths anchor themselves in the periphery of the fuel (which is restructured) leading to pellet/cladding interlocking. …
