Trimeprazine is enantioselectively degraded by an activated sludge in ready biodegradability test conditions
2018
[EN] A great number of available pharmaceuticals are chiral compounds. Although they are usually manufactured as racemic mixtures, they can be enantioselectively biodegraded as a result of microbial processes. In this paper, a biodegradability assay in similar conditions to those recommended in OECD tests of enantiomers of trimeprazine (a phenothiazine employed as a racemate) is carried out. Experiments were performed in batch mode using a minimal salts medium inoculated with an activated sludge (collected from a Valencian Waste Water Treatment Plant, WWTP) and supplemented with the racemate. The concentration of the enantiomers of trimeprazine were monitored by means of a chiral HPLC metho…
Epitalamios e himeneos. Iconografía y literatura nupcial en las cortes del Barroco.
2010
En este estudio se aborda, bajo una visión general, los textos y las imágenes presentes en algunos epitalamios e himeneos: composiciones poéticas de los siglos XVII y XVIII, realizadas en las cortes europeas con motivo de los matrimonios concertados entre sus miembros. Sus imágenes emblemáticas y simbólicas, son de gran interés para la historia del arte, pues se inspiran en las composiciones de los libros de emblemas del periodo y desarrollan temas habituales en la literatura matrimonial. No obstante, lo más significativo son los mensajes políticos que difunden, fundamentalmente los beneficios políticos de las uniones dinásticas. This study deals, from a general point of view, with the text…

Reactions at Interfaces: Oxygenation of n-Butyl Ligands Anchored on Silica Surfaces with Methyl(trifluoromethyl)dioxirane
2011
The oxygenation of n-butyl and n-butoxy chains bonded to silica with methyl(trifluoromethyl)dioxirane (1) revealed the ability of the silica matrix to release electron density toward the reacting C(2)-H σ-bond through the Si-C(1) and Si-O(1) σ-bonds connecting the alkyl chain to the surface (silicon β-effect). The silica surface impedes neither the alkyl chain adopting the conformation required for the silicon β-effect nor dioxirane 1 approaching the reactive C(2) methylene group. Reaction regioselectivity is insensitive to changes in the solvation of the reacting system, the location of organic ligands on the silica surface, and the H-bonding character of the silica surface. Reaction rates…
Ethylene polymerization catalysts based on nickel(II) 1,4-diazadiene complexes: the influence of the 1,4-diazadiene backbone substituents on structur…
1998
Abstract Thermally sensitive dialkyl nickel complexes {DAD(H,H)}Ni(CH2SiMe3)2 and {DAD(Me,Me)}Ni(CH2SiMe3)2 [DAD(X,X)=2,6-iPr2C6H4–NC(X)–C(X)N–C6H4iPr2-2,6] were synthesized and were characterized by X-ray diffraction studies on single crystals. The substituents X on the backbone of the α-diimine ligand significantly influence the conformation of the 2,6-diisopropylphenyl substituents. This effect is thought to be of crucial importance for the polymerization of ethylene when {DAD(X,X)}NiBr2/MAO is used as catalyst. The influence of the catalyst structure, pressure, and temperature on the polymerization activity, molar mass, glass transition temperature, melting temperature and branching o…
Dalla periferia al centro: I Notarbartolo duchi di Villarosa (secoli XVII-XVIII)
2012
Nella seconda metà del Seicento i Notarbartolo, grazie alle attività economiche e alle alleanze matrimoniali portate avanti da Francesco senior (1630-1704) e dai suoi due figli, Gaetano (1655-1705) e Placido senior (1657-1701), costruiscono il nucleo del proprio patrimonio fondiario e passano dalla condizione di possidenti e benestanti di Caltanissetta, alla condizione di feudatari di provincia insigniti di un titolo baronale e in possesso di tre feudi di cospicua estensione. La politica matrimoniale adottata mira all’accrescimento del patrimonio e del potere, attraverso la creazione di una rete di alleanze; talvolta i matrimoni garantiscono, tramite l’apporto delle doti, la solidità econom…
