Desarrollo y aplicación experimental de vectores virales basados en genomas de coronavirus para prevenir infecciones por rotavirus.
2009
Las infecciones por rotavirus son la causa más importante de gastroenteritis en niños menores de cinco años de edad. Se calcula que provocan unas 600.000 muertes anuales, principalmente en los países en vías de desarrollo. Una de las estrategias más prometedoras de desarrollo de nuevas vacunas consiste en el uso de virus recombinantes. Entre los sistemas virales de expresión de proteínas recombinantes más interesantes se encuentran los coronavirus. En este trabajo se aborda la producción de vectores virales basados en genomas del coronavirus TGEV (virus de la gastroenteritis porcina transmisible) para aplicarlos como vacunas experimentales de las infecciones por rotavirus. Para ello se han …
Towards Natural Engagement in Nonexhibitional Dramatic Role-Plays
2003
Modern language teaching and drama have long had a tenuous relationship. Foreign/second language teaching (F/SLT) and Language for Specific Purposes (LSP) instruction often mistakenly associate drama with learning games and role-play simulations. However, these remedial activities, though useful, offer only limited opportunities for natural speech interaction. This article argues that, as a natural dialogical process of cognitive and affective involvement, nonexhibitional dramatic role-play generates authentic meaning through action and personal commitment.
Sulla natura giuridica del nuovo canone patrimoniale di concessione, autorizzazione o esposizione pubblicitaria
2020
La centralità della nozione di tributo quale criterio di riparto della giurisdizione costringe l’interprete ad indagare se il prelievo coattivo, quand’anche il legislatore non lo qualifichi né come imposta, né come tassa, né come contributo, presenti o meno i caratteri del tributo. Attraverso gli strumenti offerti dalla giurisprudenza della Corte costituzionale lo studio analizza le norme contenute nell’art.1, commi da 816 a 836, della L. n.160/2019, con cui il legislatore ha stabilito che i Comuni, le Province e le Città metropolitane istituiscono a decorrere dal 1° gennaio 2021, in sostituzione di forme di prelievo preesistenti, il nuovo canone patrimoniale di concessione, autorizzazione …
Kun tanssi kohtaa musiikin: musiikin käyttö ja merkitys nykytanssissa
2010
Kandidaatin tutkielmani käsittelee musiikkia tanssissa. Tutkimuksessani selvitin koreografi Susanna Leinosen suhtautumista musiikkiin, ja hänen tapaansa käyttää musiikkia koreografioissaan. Tutkimuksen taustalla on sekä tanssin ja musiikin suhteen teoriaa että historiaa. Tutkimukseni perustuu pitkälti tekemääni Susanna Leinosen haastatteluun, jossa hän kertoi suhtautumisestaan musiikkiin, ja koreografioidensa musiikista. Tarkoitukseni ei ole ollut luoda yleispätevää katsausta tanssikoreografien tavoista käyttää musiikkia teoksissaan, vaan keskittyä nimenomaan Leinosen tapaan työskennellä. Susanna Leinoselle musiikki merkitsee paljon, ja se on olennainen osa hänen koreografioitaan. Hänen mus…

New simple hydrophobic proline derivatives as highly active and stereoselective catalysts for the direct asymmetric aldol reaction in aqueous medium
2008
New 4-substituted acyloxyproline derivatives with different hydrophobic properties of the acyl group were easily synthesized and used as catalysts in the direct asymmetric aldol reaction between cyclic ketones (cyclohexanone and cyclopentanone) and several substituted benzaldehydes. Reactions were carried out using water, this being the best reaction medium examined. Screening of these catalysts showed that compounds bearing the most hydrophobic acyl chains [4-phenylbutanoate and 4-(pyren-1-yl)butanoate] provided better results. The latter catalysts were successfully used in only 2 mol% at room temperature without additives to give aldol products in excellent stereoselectivities. These resu…
Stereoselective aldol reaction catalyzed by a highly recyclable polystyrene supported substituted prolinamide catalyst
2008
Polystyrene supported substituted prolinamide was used as catalyst in the aldol reaction between cyclohexanone or acetone and several substituted benzaldehydes in chloroform/water. This catalyst afforded aldol products in high yields and stereoselectivities, especially in the case of reactions performed with acetone. The catalyst was easily recovered by filtration and reused, after regeneration with formic acid, up to 22 times.
Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equil…
2016
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, and system dimensionality and size. In many regimes, we find significant improvement over adiabatic time dependent density functional theory or second Born nonequilibrium Green's function approximations. We briefly discuss the reasons for the residual discrepancies, and directions for future work.
Unraveling the nature of universal dynamics in O(N) theories
2020
Many-body quantum systems far from equilibrium can exhibit universal scaling dynamics which defy standard classification schemes. Here, we disentangle the dominant excitations in the universal dynamics of highly occupied N-component scalar systems using unequal-time correlators. While previous equal-time studies have conjectured the infrared properties to be universal for all N, we clearly identify for the first time two fundamentally different phenomena relevant at different N. We find all N >= 3 to be indeed dominated by the same Lorentzian "large-N" peak, whereas N = 1 is characterized instead by a non-Lorentzian peak with different properties, and for N = 2, we see a mixture of two cont…
