Pour une anthropologie pragmatiste et plébéienne du patrimoine : un scenario contre-hégémonique
2019
À partir de plusieurs constats, le débordement des institutions patrimoniales, l’insistance de formes citoyennes ou plébéiennes des revendications d’attachements, la prégnance de la figure du vivant, la raréfaction du futur devant la perspective anthropocénique, ce texte voudrait jeter les bases d’un scénario contre-hégémonique du patrimoine : détaché des institutions d’État, loin du marché et de sa logique néo-libérale, engagé dans des expériences de problèmes publics, sensible à la pluralité ontologies et des modes de connaissance… Some preliminary observations: too much is now asked of heritage institutions; new citizens’ and plebeian forms are emerging of asserting attachments; life-sci…
Devolution or revolution? From the rise of the individual to the supremacy of the community
2008
International audience; The devolution of power to Scotland and Wales is no marginal adjustment. Not only has the relationship between Westminster and the periphery been redefined, but the 1998 Wales and Scotland Acts have also introduced a form of quasi-federalism into British government: Scotland and Wales now enjoy a large measure of legislative and financial autonomy. Not to mention the impact in the long run for England herself and, of course, the Union. It is however probable that devolution has had other implications for Britain as a polity to the extent that it actually amounts to a major U-turn in the way one approaches the questions of belonging, democratic rights and duties, nati…
Biomarcadores en Cáncer de Próstata Resistente a la Castración Metastásico: Adquisición, Valor Pronóstico-Predictivo y Patrones de Uso en la Pr…
2020
Introducción y objetivos: El cáncer de próstata representa el segundo cáncer más frecuente en hombres, con un 15% de los casos de cáncer en varones, y es la quinta causa de mortalidad en varones. En el cáncer de próstata metastásico, los objetivos del tratamiento son la paliación de síntomas presentes (dolor) además de la prevención de la aparición de nueva sintomatología o de complicaciones (eventos esqueléticos) y la prolongación de la supervivencia. En los últimos años, el avance en el diseño de fármacos y en el conocimiento de la biología molecular del cáncer de próstata avanzado ha permitido un tratamiento más eficiente y preciso mediante el uso de biomarcadores predictivos y de respue…
Hermeneitika un ģenealoģija (M. Fuko un H.-G. Gadamers)
2015
Bakalaura darbā tiek uzrādīta domas gaita, kādā Mišela Fuko intelektuālajā darbībā iezīmējas hermeneitika, tam norisinoties caur domātāja izstrādāto ģenealoģiju kā domāšanas sistēmu pārmaiņu atklāšanas metodi. Tā tiks salīdzināta ar Hansa-Georga Gadamera izstrādāto filozofisko hermeneitiku, par salīdzinājuma izejas punktu izvēloties citādību, pētot, kā tā parādās abu domātāju risinātajos jautājumos. Tēmas aktualitāte saistāma ar tagadnes vēstures darināšanu, kas norisinās gan M. Fuko, gan H.-G. Gadamera filozofijā, atklājot vēstures ietekmi uz tagadnīgā cilvēka domāšanu, kā apzināšanās tātad var kalpot par līdzekli kā pagātnes, tā tagadnes saprašanai, sniedzot iespēju pārskatīt arī pašiem s…

Māla minerālu kompozitmateriāli kontrolētai polifenolu sorbcijai un atbrīvošanai ādas aizsarglīdzekļos
2022
Maģistra darba ietvaros tiks pētīta polifenolu grupu interkalācija mālu struktūrā un veikta iegūtā organokompleksa fizikāli ķīmisko īpašību izpēte inovatīvu un videi draudzīgu materiālu izstrādē bioekonomikas attīstībai. Pētījuma ietvaros izvēlēti rūpnieciski ražoti māla minerāli un smektīta tipa Latvijas un Lietuvas dabiskie mālieži, kas apstrādāti ar polifenolu savienojumiem no melnaugļu aroniju (Aronia melanocarpa L.), lielogu dzērveņu (Vaccinium macrocarpon), plūškoka (Sambucus nigra) un vīnogu (Vitis vinifera) izspiednēm. Polifenolu sorbcija uz māla minerāla pētīta atkarībā dažādiem parametriem - sorbenta iesvara, sorbāta koncentrācijas, pH. Raksturota sorbcijas kinētikas un temperatūr…
α-Conotoxins EpI and AuIB switch subtype selectivity and activity in native versus recombinant nicotinic acetylcholine receptors
2003
The Xenopus laevis oocyte expression system was used to determine the activities of alpha-conotoxins EpI and the ribbon isomer of AuIB, on defined nicotinic acetylcholine receptors (nAChRs). In contrast to previous findings on intracardiac ganglion neurones, alpha-EpI showed no significant activity on oocyte-expressed alpha3beta4 and alpha3beta2 nAChRs but blocked the alpha7 nAChR with an IC50 value of 30 nM. A similar IC50 value (103 nM) was obtained on the alpha7/5HT3 chimeric receptor stably expressed in mammalian cells. Ribbon AuIB maintained its selectivity on oocyte-expressed alpha3beta4 receptors but unlike in native cells, where it was 10-fold more potent than native alpha-AuIB, had…
Photoluminescence properties of S2 molecule trapped in Melanophlogite
2015
We studied the photoluminescence properties of a sample of SiO2-clathrate Melanophlogite, a crystalline microporous material which is found in nature as a rare mineral. Upon β irradiation, the material displays an intense light emission under near-UV illumination. We studied in detail this optical activity by steady-state and time-resolved photoluminescence measurements as a function of temperature. The spectroscopic properties we find can be ascribed to a population of quasi-free molecules trapped within each of the two different types of cage available in the structure of this clathrate, although the spectroscopic properties of the guest molecules are affected by their interactions with t…
Ground and first excited electronic state interaction of FAD with some β-carboline derivatives
1987
Abstract The spectrophotometric and thermodynamic properties of molecular complexes of flavine adenine dinucleotide (FAD) with some dihydro β-carboline derivatives have been investigated in aqueous solution. The molecular associations have been examined by means of electronic absorption spectra, since in each a new charge-transfer band has been located, and also the variation of the fluorescence emission of FAD on the solutions has been observed. The formation constants for the molecular complexes were determined from absorption data, using the Foster-Hammick-Wardley method. The quenching fluorescence phenomena observed in FAD is related to the concentration of the dihydro β-carboline deriv…
The Use of Stable Isotope Ratio Analysis to Trace European Sea Bass (D. labrax) Originating from Different Farming Systems
2020
This study aimed to determine whether isotopic ratio mass spectrometry (IRMS) can discriminate farmed European sea bass according to different farming systems and geographic origins. Dicentrarchus labrax of commercial size from three different rearing systems (concrete tank inland, sea cages, and extensive methods in valleys or salt works) were collected at the trading period (autumn&ndash
