Glycosidic aroma compounds of some Portuguese grape cultivars
2006
In order to evaluate the potential aroma of some Portuguese grapes, several glycosidically bound aroma compounds of ten grape varieties grown in Evora, Alentejo, Portugal, were released, identified and quantified using gas chromatography–mass spectrophotometry. White varieties were Arinto, Perrum, Rabo-de-Ovelha, Roupeiro and Antao Vaz. Red varieties were Trincadeira, Aragonez, Tinta Caiada, Moreto and Castelao. Grapes of Roupeiro and Trincadeira from five other vines in the Alentejo region were also studied. For each variety pulp and skin were analyzed separately. The compounds produced by enzymatic hydrolysis of glycoside precursors extracted from pulps and skins of these grapes were simi…
Determination of glyphosate in water samples with the combination of cation-exchange chromatography and capillary electrophoresis
2003
An analytical method for determination of pesticide Glyphosate in water as a combination of cation-exchange chromatography and capillary electrophoresis is presented. Pure water was spiked with Glyphosate at concentrations 0.1, 0.25, 0.5 and 1 mM and percolated through a strong cation-exchange column packed with Dowex 50WX4-400 resin in its H+ form. The extract was further analyzed by capillary electrophoresis in indirect detection mode. The calibration curve for the pesticide in the range 0.1–2.5 mM was linear and with high degree of reproducibility. The obtained recoveries for all the studied concentrations amount 85%. Afterwards, the possibility to determine Glyphosate at the concentrati…
Grammar types in language explain tone sequence processing in music
2009
In this ERP study, linear and center-embedded musical sequences are built according to two artificial grammar types in language, named finite state grammar (FSG) and phrase structure grammar (PSG). The aim is to prove if neural sources and processing mechanisms for artificial grammar settings across domains are the same. Isochronous pitch sequences were constructed by two interval categories (3rd and 6th) in upward and downward direction. FSG sequences, which have the general form ABAB in artificial grammar, are translated into “small up/small down/large up/large down”. PSG sequences of form A[AB]B are transposed to “small up/large up/large down/small down”. In two ERP recordings testing FS…
Correlations between productivity elements in Lolium perenne L. species for new varieties resistant to drought
2010
Perennial ryegrass is considered the most important perennial gramineous plant due to the many possibilities of use (grass and fodder) [6, 9, 15].With the increasing emphasis put on increasing the area of green space, obtaining new biological forms - varieties of the main species of gramineous plants for turf, with increased resistance to drought and land during the summer, may represent an important objective of the research companies producing such seed [6, 7].In the present study, are given researches on correlations between productivity elements, obtained in an experiment that simulates conditions of severe drought soil, to different genotypes of the species Lolium perenne L., which is …
homogeneous embeddings of SL2(C) modulo a finite sub-group.
2000
L'objet de ce travail est l'étude des variétés algébriques normales complexes munies d'une action algébrique de $SL_{2}$ et qui contiennent $SL_{2}/H$ comme orbite ouverte, $H$ étant un sous-groupe fini de $SL_{2}$.Plus précisément on définit un plongement homogène de $SL_{2}/H$ comme la donnée d'une $SL_{2}$-variété irréductible $X$ (quasi-projective ou non) contenant $SL_{2}/H$ comme orbite ouverte et d'un morphisme $SL_{2}$-équivariant de $SL_{2}$ dans $X$.Les plongements homogènes lisses ainsi que les plongements minimaux (plongements lisses et complets qui ne sont pas des éclatements d'un autre plongement lisse complet) de $SL_{2}/\{Id\}$ et de $SL_{2}/\{\pm Id\}$ ont été déterminés pa…

La mobilisation des associations catégorielles dans l’organisation des groupes professionnels des forestiers et des soignants de soins palliatifs
2015
Les associations categorielles sont, sur nos terrains, essentielles dans l’apparition et le maintien d’un groupe professionnel. Elles vont mettre en œuvre une entreprise de morale, visant a instituer l’espace specifique d’intervention du groupe comme etant d’interet public. Ce travail, qui vise a faire des professionnels les seuls intervenants legitimes, se fonde sur une entreprise de traduction des interets des professionnels et de ceux qui font appel a leurs services : il s’agit ici de montrer que les differents interets des uns et des autres ne sont pas contradictoires. Si l’entreprise de morale porte ses fruits, le nouveau segment/groupe professionnel nait et un monde professionnel peut…
