Spectroscopie des hexafluorures à nombre impair d'électrons

1995

From a theoretical point of view, a tensorial formalism adapted to the study of molecules or octahedral ions with a half-integer angular momentum has been developed for the first time. We have used here the method of projective representations, more consistent than that of double groups. A complete set of coupling coefficients and formulas, as well as the corresponding computing programs have been elaborated. This has firstly allowed to write a simple model describing the vibronic structure of colored hexafluorides. Then, somme applications of this formalism to the study of rovibronic couplings of XY6 molecules in a fourfold degenerate electronic state have been considered, especially conce…

Spectroscopic studies of semiconducting single-walled carbon nanotubes

2010

The unique nature of optical properties of single-walled carbon nanotubes (SWCNT), together with their promising potential applications, have created enormous interest towards the photophysics of SWCNT. Many aspects of carbon nanotubes originate from the electronic structure of carbon honeycomb lattice and one-dimensionality. SWCNTs exist in various chiral structures and diameters, which the optical and electrical properties are dependent on. It has been discovered that SWCNT excited states are excitonic with strong Coulomb interaction between the electron and the hole. However, many features of excitons are not yet well defined, such as absorption cross-sections, fluorescence quantum yield…

An experimental approach to oxidative stress effect on sperm motility and DNA fragmentation

2018

En el estudio de la fertilidad masculina en todas las especies animales, la movilidad espermática, junto a la concentración y morfometría son los parámetros principales y más básicos en la evaluación de la calidad de los espermatozoides. La infertilidad masculina habitualmente se asocia con tasas anormales de estos parámetros seminales. Aún teniendo, los espermatozoides tasas adecuadas de todos estos parámetros no se puede garantizar la capacidad de fertilizar y/o desarrollar un cigoto. Por lo tanto, está claro que el examen rutinario del semen y los espermatozoides en la eyaculación no puede evaluar otros parámetros importantes en el proceso de fecundación como es capacitación espermática …

From job crafting to home crafting: A daily diary study among six European countries

2019

The actions that individuals take to proactively craft their jobs are important to help create more meaningful and personally enriching work experiences. But do these proactive behaviors have implications beyond working life? Inspired by the suggestion that individuals aim for a meaningful life we examine whether on days when individuals craft their jobs, they are more likely to craft non-work activities. It also seems likely that characteristics of the home environment moderate these cross-domain relationships. We suggest that crafting crosses domains particularly when individuals gain resources through high autonomy and high workload at home. We partly supported our model through a daily…

The Far-Reaching Consequences of Job Insecurity : A Review on Family-Related Outcomes

2017

Job insecurity (JI) appears a fairly stable job stressor in working life today and likely to impair employee well-being. This review article presents the key findings of studies examining the effects of perceived JI on family well-being (e.g., marital/parental role quality, work–family conflict). The results, based on 25 published peer-reviewed studies, suggest an association between JI and impaired family well-being. Thus, JI spills over into family life as proposed in the spillover theory of work–family interface. Furthermore, studies have found some evidence of crossover effects of JI from parents to children: parents’ JI relates to negative outcomes in children. These results support th…

Three-dimensional skyrmions in spin-2 Bose–Einstein condensates

2017

We introduce topologically stable three-dimensional skyrmions in the cyclic and biaxial nematic phases of a spin-2 Bose-Einstein condensate. These skyrmions exhibit exceptionally high mapping degrees resulting from the versatile symmetries of the corresponding order parameters. We show how these structures can be created in existing experimental setups and study their temporal evolution and lifetime by numerically solving the three-dimensional Gross-Pitaevskii equations for realistic parameter values. Although the biaxial nematic and cyclic phases are observed to be unstable against transition towards the ferromagnetic phase, their lifetimes are long enough for the skyrmions to be imprinted…

Spin caloric transport from density-functional theory

2019

Spin caloric transport refers to the coupling of heat with spin transport. Its applications primarily concern the generation of spin currents and control of magnetisation by temperature gradients for information technology, known by the synonym spin caloritronics. Within the framework of ab initio theory, new tools are being developed to provide an additional understanding of these phenomena in realistic materials, accounting for the complexity of the electronic structure without adjustable parameters. Here, we review this progress, summarising the principles of the density-functional-based approaches in the field and presenting a number of application highlights. Our discussion includes th…

Social psychological aspects of ACL injury prevention and rehabilitation: An integrated model for behavioral adherence

2017

Managing rehabilitation for ACL injury is dependent on uptake of, and compliance with, medical and safety recommendations. In this paper, we propose a multi-theory model that integrates self-determination theory and the theory of planned behavior to identify the motivational determinants ACL injury prevention and management behaviors and the processes involved. nonPeerReviewed
