Systèmes financiers et canaux de transmission de la politique monétaire
2010
This dissertation analyses the consequences of transformations in the financial sphere on the transmission channels of decisions in monetary policy in industrialized countries over the past several years. We observe that as a result of these transformations, banking institutions have evolved from an originate to hold model to an originate to distribute model. This has enabled banks to turn more toward derivative products and credit risk transfer instruments. We demonstrate that these techniques of active/passive management have completely revolutionized the theoretical foundations of traditional channels and in particular the credit channel. Our analysis of these landmark changes is organiz…
Quasispecies dynamics and molecular evolution of human norovirus capsid P region during chronic infection.
2009
In this novel study, we have for the first time identified evolutionarily conserved capsid residues in an individual chronically infected with norovirus (GGII.3). From 2000 to 2003, a total of 147 P1-1 and P2 capsid sequences were sequenced and investigated for evolutionarily conserved and functionally important residues by the evolutionary trace (ET) algorithm. The ET algorithm revealed more absolutely conserved residues (ACR) in the P1-1 domain (47/53, 88 %) as compared with the P2 domain (86/133, 64 %). The capsid P1-1 and P2 domains evolved in time-dependent manner, with a distinct break point observed between autumn/winter of year 2000 (isolates P1, P3 and P5) and spring to autumn of y…
Chionaeosides A–D, Triterpene Saponins from Paronychia chionaea
2007
Four new triterpenoid saponins, chionaeosides A-D (1-4) were isolated from the roots of Paronychia chionaea. On the basis of their spectroscopic data, the structures of the new saponins were established as 3-O-alpha-L-arabinopyranosylgypsogenic acid 28-O-beta-D-glucopyranosyl-(1--3)-beta-D-glucopyranosyl-(1--6)-beta-D-glucopyranoside (1), 3-O-alpha-L-arabinopyranosylgypsogenic acid 28-O-beta-D-glucopyranosyl-(1--6)-beta-D-glucopyranoside (2), 3-O-alpha-L-arabinopyranosylgypsogenic acid 28-O-beta-D-glucopyranoside (3), and 3-O-alpha-L-arabinopyranosylgypsogenic acid (4).
Triterpene Glycosides from the Roots of Astragalus flavescens
2007
Six new triterpene saponins, 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-(1-->2)-beta-D-glucuronopyranosyl-21-epi-kudzusapogenol A (1), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta-D-glucuronopyranosyl-21-epi-kudzusapogenol A (2), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-(1-->2)-beta-D-glucuronopyranosyl-22-O-beta-D-glucopyranosyl-21-epi-kudzusapogenol A (3), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta-D-glucuronopyranosyl-22-O-beta-D-glucopyranosyl-21-epi-kudzusapogenol A (4), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-(1-->2)-beta-D-glucuronopyranosyl-22-O-alpha-L-arabinopyranosyl-21-epi-kudzus…
IL RISARCIMENTO DEL DANNO DA LESIONE DI INTERESSI DI DERIVAZIONE SPORTIVA: NOTA DI COMMENTO A TAR LAZIO 11146/2017 E 1163/2017
2017
Con le sentenze che qui si annotano, il Tar Lazio si pronuncia sulla questione del risarcimento del danno derivante dalla lesione di una situazione giuridica soggettiva per effetto dell’irrogazione di una sanzione disciplinare sportiva.
Le tutele contrattuali
2017
I dispositivi di tutela decritti all’art. 1453 c.c. non esauriscono l’apparato rimediale che l’ordinamento appronta in caso di inadempimento di un contratto a prestazioni cor-rispettive: la disciplina codicistica delle obbligazioni (art. 1218 c.c.) prevede infatti che l’inadempimento espone il debitore al risarcimento del danno e cioè alla responsabilità contrattuale [v. supra cap. XIV § 10.2], ma quando l’inadempimento consiste nella mancata o inesatta esecuzione di una prestazione di un contratto sinallagmatico, in cui cioè le prestazioni sono legate da un vincolo di corrispettività, allora alla parte fedele del contratto si offre sia il rimedio della responsabilità, sia quello della riso…
Le trou noir de synthèse, un divertissement éducatif ?
2013
National audience; Au-delà de l'argument pédagogique, l'emploi d'images de synthèse dans les émissions télévisées sur l'astronomie relève aussi du spectacle ludique, que certains créateurs assument sans complexe. Cet article propose justement de confronter deux programmes mettant en scène - de manière diamétralement opposée - la découverte d'un super-trou noir au centre de la Voie Lactée, afin de révéler leur promesse respective, la manière dont ils la tiennent et questionner ainsi la pertinence de la dichotomie traditionnelle " éducation / divertissement ".
Tēlu raksturojums un galvenās tēmas Džeinas Ostinas romānā „Lepnums un aizspriedumi” un tā ekranizācijā
2017
Bakalaura darbs atspoguļo angļu rakstnieces Džeinas Ostinas noveles “Lepnums un aizspriedumi” (1813) un angļu kinorežisora Džo Raita filmas “Lepnums un aizspriedumi” (2005) analīzi. Pētījuma galvenais akcents ir vērsts uz apskatu par līdzībām un atšķirībām novelē un tās ekranizācijas tēlu raksturošanā un svarīgākajās tēmās, kuras ikdienas lasītājs vai skatītājs nevar pamanīt. Pētījuma metodes ietver tēlu raksturošanu, tēmu un filmu teorētisko materiālu, kā arī izvēlētās noveles un tās ekranizējuma analīzi. Pēc pētījuma veikšanas Bakalaura darba autors nonāk pie slēdziena, ka pēc Džeinas Ostinas noveles “Lepnums un aizspriedumi” Džo Raita režisētā filma “Lepnums un aizspriedumi” meistarīgi a…
Cooperation in Rural Areas as a Local System Development Opportunity
2017
The development of rural areas requires the adoption of technology innovation and market approach strategies without departing from the specific features of local production systems, such as agricultural practices and the wealth of knowledge of operators. It is even better the exploitation of these resources to characterize the competitive positioning of territorial systems. In this framework, the cooperative Rinascita, which works in an internal rural area of Sicily region (Southern Italy), represents an attempt to maintain agricultural activities, traditions and rural culture as well as to promote and contribute to the development of the area by giving value to and promoting, a typical lo…
Comparative study assessing effects of sonic hedgehog and VEGF in a human co-culture model for bone vascularisation strategies.
2011
The morphogen sonic hedgehog (Shh) seems to mediate adult repair processes in bone regeneration and vascularisation. In this study we investigated the effects of Shh on co-cultures consisting of human primary osteoblasts and outgrowth endothelial cells in terms of angiogenic activation and vessel maturation in comparison to the treatment with the commonly used proangiogenic factor, VEGF. Both, stimulation with VEGF or Shh, leads to an increase in the formation of microvessel-like structures compared to untreated controls. In contrast to VEGF, proangiogenic effects by Shh could already be observed after 24 h of treatment. Nevertheless, after 14 days the angiogenic activity of OEC was compara…
