Multidentate Tetrahydrofurfuryloxide Ligand in a Ziegler−Natta Catalyst Studied by Molecular Modeling

2008

The transition from a generation III Ziegler-Natta catalyst with a monodentate Lewis base to a more modem generation 1V/V system, containing a tetrahydrofuran derivative, the tetrahydrofurturyloxide C 4 H 7 O-CH 2 O - bidentate ligand (THFFO), was studied by means of molecular modeling and DFT calculations. This particular ligand was carefully chosen so that it remained in the titanium coordination sphere in the model active site. With such a constraint, the dual role of tetrahydrofurfuryloxide was identified: it was demonstrated how the presence of this ligand limits the number of isomeric active sites as well as enhances the selectivity of the species that can still exist. The results ind…

Modulation of excitatory and inhibitory circuits for visual awareness in the human right parietal cortex.

2005

The balance of specific patterns of excitation and inhibition in critical regions of both hemispheres could be relevant in orienting attention over the extrapersonal space. In the present study a group of normal subjects had to detect small rectangular stimuli presented briefly on a computer screen in three different conditions: unilateral presentation either to left or right visual periphery or bilateral simultaneous presentation. Paired transcranial magnetic stimulation (TMS), was applied over the right parietal cortex 150 ms after the presentation of the visual stimuli with different inter-stimulus intervals (ISIs: 1, 3,5 and 10 ms). When paired TMS was applied 150 ms, but not 100 ms, af…

La ciutat il·luminada. València en els textos de Max Aub.

2018

La ciutat de València apareix una vegada rere l’altra en l’obra de Max Aub. De vegades, en dates properes a la infantesa de l’autor, els finals de la dècada dels anys deu. Unes altres —la majoria—, en els anys de la Guerra Civil, en les novel·les del cicle El laberinto mágico, especialment en Campo abierto i Campo de los almendros. En aquest article analitzarem la textura d’aquesta representació, com és la València representada, quins són els trets que Aub en destaca, en quins barris es mouen els seus personatges; és a dir, de quina manera Max Aub, des de l’exili, basteix el plànol de la ciutat recordada amb sorprenent precisió, vinculant‑lo a olors, sons, sensacions i noms propis, de lloc …

L'intérêt de l'animation comme support au code de la route pour les candidats sourds

2018

Entretiens Jacques Cartier, LYON, FRANCE, 13-/11/2018 - 14/11/2018; This article focuses on the interest of using dynamic Highway Code learning materials, particularly for deaf people who present low temporal skills. Twenty-one deaf and 24 hearing candidates of Highway Code were involved in a decision-making task. Four types of driving situations (overtaking, insertion on roundabout, insertion on highway and crossing an intersection) from which participants have to decide to go or not to go were presented in two different formats (static vs animated) and in two level of difficulty (simple vs complex). Results showed better performance in animated than in static condition, especially in deaf…

DFT analysis of titanium complexes with oxygen-containing bidentate ligands

2003

Strength of the TiO co-ordinate bond in several titanium complexes with bidentate ligands has been investigated by means of DFT. Mutual interaction of particular donors and their influence on Lewis acidity of the central atom have also been studied. The energy of ligand binding ranges from −19 to −454 kJ/mol, depending on the kind of donors. Calculations confirm that a strong donor, alkoxide anion, co-ordinatively saturates the titanium and makes binding of new ligands less exoenergetic. On the contrary, two oxygen atoms of similar donor number do not have much influence on each other. Strength of the TiO bonds in titanium complexes with certain oxygen-containing bidentate ligands has bee…

Childhood Trauma increases suicidal behaviour in a treatment-resistant depression population: a FACE-DR report

2021

International audience; Objective: In addition to heredity, exposure to early-life adversity is an important predisposing risk factor of suicidal behaviour. Although the association between Childhood Trauma (CT) and suicide risk is well documented, interactions between CT and suicidal behaviour in Treatment-Resistant Depression (TRD) populations have received little coverage. This study aimed to evaluate i) association between CT and suicidal behaviour in a TRD population, and ii) the role of personality traits and impulsiveness as potential factors of mediation in these associations.Methods: Patients were recruited from a cohort of the French network of TRD expert centers. Depressive sympt…

Taenia asiatica: the Most Neglected Human Taenia and the Possibility of Cysticercosis

2013

Not only Taenia solium and Taenia saginata, but also Taenia asiatica infects humans. The last species is not included in the evaluation of the specificity of the immunodiagnostic techniques for taeniasis/cysticercosis. There is currently no specific immunodiagnostic method for T. asiatica available. Therefore, due to the fact that molecular techniques (the only tool to distinguish the 3 Taenia species) are normally not employed in routine diagnostic methods, the 2 questions concerning T. asiatica (its definite geographic distribution and its ability to cause human cysticercosis), remain open, turning T. asiatica into the most neglected agent of human taeniasis-cysticercosis.
