Development of an ad hoc natural whey starter culture for the production of Vastedda della valle del Belìce cheese

2013

This work was aimed to characterize the autochthonous lactic acid bacteria (LAB) of PDO Vastedda della valle del Belìce cheeses, produced in several dairy factories, for the development of an ad hoc starter culture preparation for the production of this cheese. To this purpose, winter and spring productions were analysed, in order to isolate LAB adapted to perform the fermentation at low temperatures. Plate counts showed the total microbial counts (TMC) till levels of 9 -1almost 10 CFU g and all cheese samples were dominated by coccus LAB. Not all samples were positive for the presence of enterobacteria, but when they were found their concentrations were at similar levels in both seasons. A…

Evolution of terminology related to attention to diversity through the various legislative reforms in Spain

2016

espanolIntroduccion. En este articulo se presenta un analisis detallado de los diferentes cambios legislativos desde que se comenzo a hablar de la “Atencion a la diversidad” en el sistema educativo en Espana. Metodo. Este estudio se ha centrado en analizar el proceso de reforma legal que se ha seguido a lo largo de los anos, y ha intentado enfatizar el vacio legal que se viene sufriendo desde una intervencion educativa de la diversidad, en todas las posibilidades comprendidas y especificadas en la legislacion vigente. Resultados y discusion. Este analisis reflexivo detallado ha permitido mostrar como estos cambios no han sido ni numerosos ni significativos para el desarrollo de un curriculo…

CO2 effects on behaviour and reproduction of nesting fish species

2014

Ocean acidification is a global phenomenon linked to the CO2 absorption by the surface of the sea. This increasing process leads to a rise of the CO2 partial pressure (pCO2) that changes the seawater chemistry. It is known that such changes have negative consequences for many marine organisms. However, the effects of acidification on fishes are yet poorly understood. Fishes have been hypothesized to be more physiologically tolerant to elevated CO2. Nevertheless, many researches have described severe effects of altered pCO2 levels on fish behaviour, especially during early life history stages, and only few authors have focused on fish reproduction. The aim of my Ph.D. research is to investig…

Apolar versus polar solvents: a comparison of the strength of some organic acids against different bases in toluene and in water

2010

The constants of ion-pair formation with 3-nitroaniline (3NO(2)A) for eight halogenoacetic acids (HAAs, 3a-h: TFA, TCA, TBA, DFA, DCA, DBA, MCA, and MBA), and five 2,2-dichloroalkanoic acids containing 3-8 carbon atoms (HAs, 5a-e: DCPA, DCBA, DCMBA, DCVA, and DCOA) have been determined in TOL at 298.1 K. The results obtained brought to evidence for HAAs the formation of ion-pairs with two different stoichiometries (base-acid, 1:1 or 1:2), while in contrast the HAs furnish only the 1:1 pairs. The different steric and electronic requirements of HAAs and HAs seem to be responsible for such an unlikely behavior. At the same time, the acid-catalyzed MRH of the (Z)-phenylhydrazone of 5-amino-3-be…

Direct Visualization of Molecule Deprotonation on an Insulating Surface

2012

Elucidating molecular-scale details of basic reaction steps on surfaces is decisive for a fundamental understanding of molecular reactivity within many fields, including catalysis and on-surface synthesis. Here, the deprotonation of 2,5-dihydroxybenzoic acid (DHBA) deposited onto calcite (101;4) held at room temperature is followed in situ by noncontact atomic force microscopy. After deposition, the molecules form two coexisting phases, a transient striped phase and a stable dense phase. A detailed analysis of high-resolution noncontact atomic force microscopy images indicates the transient striped phase being a bulk-like phase, which requires hydrogen bonds between the carboxylic acid moie…

Identification and quantification of phosphatidylcholines containing very long chain polyunsaturated fatty acid (VLC-PUFA) in bovine and human retina…

2010

The retina is one of the vertebrate tissues with the highest content in polyunsaturated fatty acids (PUFA). A large proportion of the retinal glycerophospholipids, especially those found in photoreceptor membranes, are dipolyunsaturated molecular species. Among them, dipolyunsaturated phosphatidylcholine molecular species are known to contain very long chain polyunsaturated fatty acids (VLC-PUFA) from the n-3 and n-6 series and having 24 to 36 carbon atoms (C24 to C36) and four to six double bonds. Recent interest in the role of VLC-PUFA arose from the findings that a protein named ELOngation of Very Long chain fatty acids 4 (ELOVL4) is involved in their biosynthesis and that mutations in E…
