Nitric Oxide: Probably the in Vivo Mediator of the Bisulfite’s Effects  [PDF]
Loris Grossi
Journal of Biosciences and Medicines (JBM) , 2014, DOI: 10.4236/jbm.2014.27001
Abstract: The use of bisulfite in food and beverage preservation, as well as in commercial goods and pharmaceuticals as antimicrobial agents is well known, but not very much is reported on its action in vivo. It has been stressed that its action is connected to the presence of NO, and the only reported/ hypothesized evidence concerns the possible interaction with GSNO (S-nitrosoglutathione), an NO releaser. In this light, we investigated the interaction between GSNO and the bisulfite in an aqueous medium at pH = 6.4; actually, a positive effect of the sulfite was evidenced. i.e., the S-nitrosoglutathione becomes a more efficient NO-releaser. But, the nitrite is the real pool of NO in vivo, therefore we investigate its interaction with the bisulfite in an aqueous acidic solution at pH = 6.4; this time, a definitely efficient and abundant NO release, 3.61 times higher compared to the GSNO, has been evidenced. Therefore, these results allow hypothesizing a fundamental role of NO in the bisulfite’s action in vivo, or most probably the bisulfite acts simply as cofactor of NO-releasers.
Prediction of Outcome in the Vegetative State by Machine Learning Algorithms: A Model for Clinicians?  [PDF]
Loris Pignolo, Vincenzo i Lagan
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.46044
Abstract: Purpose of this study was to compare different Machine Learning classifiers (C4.5, Support Vector Machine, Naive Bayes, K-NN) in the early prediction of outcome of the subjects in vegetative state due to traumatic brain injury. Accuracy proved acceptable for all compared methods (AUC > 0.8), but sensitivity and specificity varied considerably and only some classifiers (in particular, Support Vector Machine) appear applicable models in the clinical routine. A combined use of classifiers is advisable.
The rise and fall of the third position: Bolivia, Perón and the Cold War, 1943-1954
Zanatta,Loris;
Desarrollo Económico (Buenos Aires) , 2006,
Abstract: the doctrine of the third position drawn by peron between 1946 and 1955 was an attempt to find an alternative to the opposition between the liberal west and the communist east. in practical terms, it resulted in the project to create a bloc of latin-american nations independent both from washington and from moscow. peron's project interpreted the region's peaking nationalist feelings and amounted to a challenge on the united states in the toughest phase of the cold war. however, the third position soon revealed the limitations -economic weakness, diplomatic dilettantism- that led to its demise and sub-ordination to the iron logic of the cold war. this article examines one of those limitations, scarcely explored by the literature: the hegemonic, even sub-imperialist aspect that the third position assumed in the eyes of argentina's neighboring countries. this trait would eventually induce those countries to seek the protection of a strong and distant empire, the united states, before submitting to the ambitions of a weaker, closer power, peron's argentina. this article reconstructs such political dynamics drawing on the competition between washington and peron for the control of bolivia between 1943 and 1955 as an example.

Ugovor o osiguranju od odgovornosti organizatora portskog natjecanja
Loris Belani?
Zbornik Radova Pravnog Fakulteta u Splitu , 2011,
Abstract: Organizator portskog natjecanja mo e biti suo en s brojnim zahtjevima za naknadu tete koju za vrijeme ili povodom portskog natjecanja mogu pretrpjeti razni o te enici: posjetitelji (gledatelji) portskog natjecanja, sami natjecatelji, ali i ostale tre e osobe. U tom slu aju pokri e iz ugovora o osiguranju od odgovornosti pru a za titu organizatoru portskog natjecanja od financijskih izdataka u obliku naknade tete koja bi se trebala isplatiti navedenim o te enicima. U radu se prikazuje tko se sve mo e pojaviti kao ugovaratelj ugovora o osiguranju od odgovornosti organizatora portskog natjecanja te tko se sve mo e pojaviti u polo aju o te enika (zbog postojanja njegova vlastitog i neposrednog prava prema osiguratelju). Potom se govori o predmetu osiguranja (osiguranim riziku) u ovoj vrsti ugovora o osiguranju, eventulanim isklju enjima iz osigurateljskog pokri a te o osiguranim slu aju i trenutku njegovog nastupa.
Ugovor o osiguranju (tro kova) pravne za tite u djelatnosti sporta
Loris Belani?
Zbornik Radova Pravnog Fakulteta u Splitu , 2012,
Abstract: Ovom vrstom ugovora o osiguranju osiguratelj se obvezuje pla ati sve tro kove pravne za tite osiguraniku (odvjetni ke tro kove, sudske i upravne pristojbe, tro kove vje ta enja i dr.) u razli itim situacijama i djelatnostima u kojima je potrebno ostvarivanje njegovih pravnih interesa. Obveza osiguratelja za pla anjem tro kova postoji u gra anskim parnicama, upravnim postupcima, prekr ajnim i kaznenim postupcima. Sport kao djelatnost nesumnjivo je povezana s rizikom nastanka pravnih tro kova (sporovi iz ugovora sporta a, sporovi naknade tete, kaznena i prekr ajna odgovornost osoba u sustavu sporta i dr.). Pri tome se nagla ava da potreba za pravnom za titom mora biti u vezi s obavljanjem sportske djelatnosti, odnosno mora proizlaziti iz takve djelatnosti. U radu se namjerava obraditi specifi nost rizika pravne za tite u sportskoj djelatnosti, o odre ivanju osiguranog slu aja te i specifi nim pravima i obvezama ugovornih strana. Pri tome je jedno od najva nijih prava osiguranika da sam izabere odvjetnika koji e ga zastupati na tro ak osiguratelja. Istovremeno se nagla ava da je ova vrsta osiguranja u Hrvatskoj tek u za ecima pa ne postoji trenutna adekvatna ponuda ovakvog pokri a na hrvatskom tr i tu osiguranja.
Peron e il miraggio del Blocco latino Di come la guerra fredda allargò l’Atlantico Sud
Zanatta, Loris
Anuario de Estudios Americanos , 2006,
Abstract: This article is based upon a multi-archival research in the diplomatic archives of seven different countries: Argentina, Brazil, Chile, Spain, Italy, Perù and Portugal. It analyzes the attempt of the Peròn government to form a bloc of Latin countries, gathering under its hegemony, and with the support of the Vatican, the catholic nations of Europe and America. Known as the “third position”, the idea of creating such a bloc failed once the Cold War imposed its rules, laying the ground for an odd alliance between most catholic countries, the Vatican and the United States. As a consequence, Peròn’s policy abandoned its religious matrix and drifted progressively toward third-worldist horizons. At the same time, the abortion of the Latin bloc showed the capability of the bipolar system to erode the notion of a Latin civilization, diluting it into the broadest one of the Christian West Basada en los archivos diplomáticos de Argentina, Brasil, Chile, Espa a, Italia, Perú y Portugal, esta investigación analiza el intento del gobierno de Perón de formar un bloque de países latinos capaz de reunir bajo su hegemonía y con la legitimación de la Santa Sede las naciones católicas de Europa y de América. Conocido como la “tercera posición”, ese bloque fracasó a medida que la guerra fría imponía sus reglas y creaba las condiciones de una inédita alianza entre la mayoría de los países católicos y el Vaticano con Estados Unidos. Como consecuencia la política peronista se alejó de su origen confesional para evolucionar hacia una ideología cada vez más tercermundista. Al mismo tiempo el aborto del bloque latino demostró que el sistema bipolar destruía la noción de civilización latina diluyéndola en la más amplia de Occidente cristiano
Does Economic Vulnerability Affect Social Cohersion? Evidence from a Comparative Analysis
Loris Vergolini
The Canadian Journal of Sociology , 2011,
Abstract: This article explores the relationship between social cohesion andsocial inequalities in Europe. The analysis is built around two main research questions: Does economic vulnerability exert an impact on the level of social cohesion? Does social class mediate between economic vulnerability and social cohesion? The comparative analysis is based on the welfare regimes perspective. In my opinion, welfare state is relevant because it influences not only the relationship between social class and economic vulnerability, but also the link betweensocial cohesion and economic vulnerability. The empirical analysis, based on data from the “European Quality of Life Survey” collected by the European Foundation for the Improvement of Living and Working Conditions in 2003, shows that economic vulnerability does influence social cohesion and that social class and welfare regime are partially able to attenuate this effect.
Boltzmann vs Gibbs: a finite-size match
Loris Ferrari
Physics , 2015,
Abstract: The long standing contrast between Boltzmann's and Gibbs' approach to statistical thermodynamics has been recently rekindled by Dunkel and Hilbert [1], who criticize the notion of negative absolute temperature (NAT), as a misleading consequence of Boltzmann's definition of entropy. A different definition, due to Gibbs, has been proposed, which forbids NAT and makes the energy equipartition rigorous in arbitrary sized systems. The two approaches, however, are shown to converge to the same results in the thermodynamical limit. A vigorous debate followed ref.[1], with arguments against [2,3] and in favor [4,5,6,7] of Gibbs' entropy. In an attempt to leave the speculative level and give the discussion some deal of concreteness, we analyze the practical consequences of Gibbs' definition in two finite-size systems: a non interacting gas of N atoms with two-level internal spectrum, and an Ising model of N interacting spins. It is shown that for certain measurable quantities, the difference resulting from Boltzmann's and Gibbs' approach vanishes as the inverse square rrot of N, much less rapidly than the 1/N slope expected. As shown by numerical estimates, this makes the experimental solution of the controversy a feasible task.
On the performance of algorithms for the minimization of $\ell_1$-penalized functionals
Ignace Loris
Mathematics , 2007, DOI: 10.1088/0266-5611/25/3/035008
Abstract: The problem of assessing the performance of algorithms used for the minimization of an $\ell_1$-penalized least-squares functional, for a range of penalty parameters, is investigated. A criterion that uses the idea of `approximation isochrones' is introduced. Five different iterative minimization algorithms are tested and compared, as well as two warm-start strategies. Both well-conditioned and ill-conditioned problems are used in the comparison, and the contrast between these two categories is highlighted.
