Characterization of waxes used in pictorial artworks according to their relative amount of fatty acids and hydrocarbons by gas chromatography.

2005

A study attempted to characterize natural waxes used in pictorial works of art was carried out by means of gas chromatography. The analytical treatment requires prior hydrolysis of the waxes to release the fatty acids (FA) (myristic (myr), palmitic (pal), oleic (ole), stearic (ste), araquidic (ara), behenic (beh), lignoceric (lig), cerotic (cer)) from the main esters of the waxes. The formation of volatile derivatives of the fatty acids was carried out by derivatization with ethyl choroformate (ECF). This derivatization reagent was chosen due to the speed, safety and quantitativity of the reaction. The analyzed hydrocarbons were n-eicosane, n-heneicosane, n-docosane, n-tricosane, n-tetracos…

Reciprocal Enzymatic Interference of Carnitine Palmitoyltransferase I and Glycerol-3-Phosphate Acyltransferase in Purified Liver Mitochondria

2006

(i) Highly purified mitochondrial fractions were practically devoid of microsomal contamination and of acyl-CoA ligase activity. (ii) In mitochondria, glycerol-3-phosphate acyltransferase (GPAT) activity was supported by two enzymes, the first being very active at low palmitoyl-CoA / albumin ratios and sensitive to external agents (external form), the second being detected only at higher palmitoyl-CoA / albumin ratios and insensitive to external agents (internal form). (iii) Carnitine palmitoyltransferase I (CPT I) activity was shown to inhibit external GPAT activity only. (iv) Glycerol-3-phosphate exerted an inhibitory effect on CPT I, even when GPAT was inactive. Reciprocal interaction of…

Carnitine transport in volume-overloaded rat hearts

1995

Carnitine concentration in tissue is generally related to mitochondrial volume-density and ability to oxidize fatty acids. The highest tissue carnitine has been detected in ventricular myocardium which, compared to other tissues, presents elevated rates of oxidative phosphorylation [1]. The ability of cardiac mitochondria to oxidize long chain fatty acids is also much higher when compared to skeletal muscle or liver sarcosomes (Table 1). Paradoxically enough, it has been known for many years [3–5] that the heart is missing γ-butyrobetaine hydroxylase [6, 7], the last enzyme of carnitine synthesizing pathway, and that in the myocardium of different species including man, the carnitine synthe…

Pauls rectifiable and purely Pauls unrectifiable smooth hypersurfaces

2020

This paper is related to the problem of finding a good notion of rectifiability in sub-Riemannian geometry. In particular, we study which kind of results can be expected for smooth hypersurfaces in Carnot groups. Our main contribution will be a consequence of the following result: there exists a -hypersurface without characteristic points that has uncountably many pairwise non-isomorphic tangent groups on every positive-measure subset. The example is found in a Carnot group of topological dimension 8, it has Hausdorff dimension 12 and so we use on it the Hausdorff measure . As a consequence, we show that any Lipschitz map defined on a subset of a Carnot group of Hausdorff dimension 12, with…

Danza oriental, género y políticas coloniales: del cabaret moderno al mercado global de la cultura.

2015

La tesis doctoral “Danza oriental, género y políticas coloniales: del cabaret moderno al mercado global de la cultura” es un análisis historicista de la internacionalización de la práctica de la denominada danza del vientre u oriental desde la aparición de su forma escénica, dentro de la cultura urbana de fin-de-siècle, hasta la actualidad. En cuanto al marco teórico y metodología, este estudio parte de la historia y la etnología de la danza para ofrecer una aproximación interdisciplinar sirviéndose de los estudios de género, poscoloniales y culturales. La danza oriental es entendida como un sistema de representación simbólica que siendo expresión del cuerpo sexuado revela, particularmente,…

The castle's Hermitage of Yecla (Region of Murcia) constituted during the 13th to 16th centuries the first parish of the population, hosting a triptych-shaped altarpiece presided over by a tempera painting on wood of Our Lady of Humility or "Virgo Lactans", dated around 1370 and attributed to the painter Barnaba da Modena, which was the titular image of the mentioned temple under the title of Our Lady of the Incarnation, until at the end of the 18th century it changed ownership for the Conception of Our Lady. The table at averages of the eight hundred was placed in an a loft, appropriating it at the beginning of the 20th century by the retired military Pascual Spuche y Lacy, who sold it aro…

Semigenerated Carnot algebras and applications to sub-Riemannian perimeter

2021

This paper contributes to the study of sets of finite intrinsic perimeter in Carnot groups. Our intent is to characterize in which groups the only sets with constant intrinsic normal are the vertical half-spaces. Our viewpoint is algebraic: such a phenomenon happens if and only if the semigroup generated by each horizontal half-space is a vertical half-space. We call semigenerated those Carnot groups with this property. For Carnot groups of nilpotency step 3 we provide a complete characterization of semigeneration in terms of whether such groups do not have any Engel-type quotients. Engel-type groups, which are introduced here, are the minimal (in terms of quotients) counterexamples. In add…

Contributo allo studio delle riproduzioni (non solo) meccaniche ex art. 2712 c.c. e della loro valutazione, anche alla luce delle recenti oscillazion…

2020

L’autore, muovendo da uno scritto di Carnelutti del 1924 affronta talune problematiche in tema di riproduzioni ex art. 2712 c.c. La riproduzione non disconosciuta ha carattere di prova vincolante per il giudice, mentre il disconoscimento priva la riproduzione esclusivamente di tale efficacia rafforzata, affidandone la valutazione al prudente apprezzamento del giudice ex art. 116 c.p.c. La riproduzione disconosciuta potrà essere oggetto di una verificazione intrinseca, ossia diretta ad accertarne la manipolazione. Per completarla il giudice potrà affidarsi a una prova scientifica, con tut-te le problematiche connesse. The author, moving from an article written by Carnelutti in 1924, deals wi…

Graphic hyperboles and critical dystopia in Miguel Brieva's drawings

2020

Dorothée CHOUITEM, Louis IMPERIALE, Joanna WILK-RACIĘSKA (coord); International audience; Dans les dessins de Miguel Brieva (Séville, 1974), l’humour participe assurément d’un exercice de déconstruction. Critique, moqueur, destructeur, son geste graphique se complait dans la propension à l’exagération, à l’hyperbole et au « superlatif ». L’intention est de mettre au jour les nouvelles formes de violence de la période présente de l’hypercapitalisme. La félicité n’étant guère questionneuse, c’est le dessin, en tant qu’outil de monstration, qui sera chargé de présenter les contreparties de nos jouissances acquises. Les images auront ici pour ambition de participer au renversement des insoutena…
