Within multi-Higgs-doublet models, one can impose symmetries on the Higgs potential, either discrete or continuous, that mix several doublets. In two-Higgs-doublet model any such symmetry can be conserved or spontaneously violated after the electroweak symmetry breaking (EWSB), depending on the coefficients of the potential. With more than two doublets, there exist symmetries which are always spontaneously violated after EWSB. We discuss the origin of this phenomenon and show its similarity to frustration in condensed matter physics. [less ▲]

Tagitinin C, an antiplasmodial compound, identified as one major compound of the subtropical medicinal plant, Tithonia diversifolia, was, determined by FT-IR spectroscopy method. The crude ether extracts from aerial parts of the plant were evaporated to dryness and re-dissolved in tetrachloroethylene (C2Cl4) before analysis. The magnitude of the absorbance of the very specific C=O stretching vibration (v(c=o)) at 1664.8 cm(-1) was exploited in order to quantify tagitinin C. The determination coefficient (r(2)) of the calibration scale was 0.9994, the detection limit was lower than 3 mug ml(-1) and the quantification limit was lower than 10 mug ml(-1). Recovery values from 100.5 to 101.7% were found for spiked concentration levels from 19.91 to 89.95 mug ml(-1). The main characteristics of the curves obtained from the calibration standards and from the standard addition technique were not statistically different (Student t-test) suggesting that matrix effects were negligible. The results obtained for the determination of tagitinin C in the crude ether extract from aerial parts of T diversifolia by LC and FT-IR spectroscopic method agreed well: 0.76 +/- 0.02 and 0.773 +/- 0.009, of tagifinin C in dried plant respectively.

The aim of this study was to investigate the structure and the film-forming capacity of the polysaccharide kefiran (extracted from kefir grains) using FTIR spectroscopy. Different forms of the polysaccharide (kefiran solution, frozen kefiran and kefiran pellet) were subjected to infrared measurements. Solutions of kefiran with different concentrations of glycerol (5, 7.5, 10 or 15% w/w) were prepared. The film-forming solutions of kefiran and the characteristics of the resulted biofilms were tested. The biofilm obtained from kefiran solution with 7.5% w/w glycerol had the best characteristics (transparency and elasticity). FTIR spectroscopy results showed that the structural integrity of kefiran was maintained in biofilms, which highlights the relationship between chemical composition and future applications of the polysaccharide.

While analysing the psychological functioning of sex reassignment candidates, it appeared that they frequently use the mechanism which consist in taking refuge in passivity and fantasies so that they can avoid displeasing situations, responsibilities and decisions making. This unconscious process, identified by Exner in the Rorschach as the Snow-White Syndrome seems to take place in a specific way regarding the real situation faced by the sex reassignment candidates: the achievement of their aim (the sex reassignment) actually depends on the medical crew (doctors, psychologists, surgeons). We wondered if this fact consisted in a stylistic component, that is to say a stable feature of transsexuals' personality or in an opportunist defence. The dependence on the third, executor and decision-maker could be seen either as the indication of this feature being a favourable condition to the construction of the transsexual Issue or a consequence the transsexual's real situation. The hypothesis of the situational use of this process is studied by comparing the frequency of the Snow-White Syndrome during the moment before giving the surgical response with its appearance frequency after the sex reassignment. The individuals' retest (7MF/7FM) after the operation brings favourable arguments to the second interpretation since the process stops being used as soon as the passive dependence position doesn't exist anymore (the Snow-White Syndrome disappears in 70% of cases). So, as the goals are reached (the medico-surgical transformation materialising the desire), the flight in fantasies and passivity is not necessary anymore and the dependence on contributors disappears. During the psychological follow-up, attention should be paid to this psychic impact of anatomical reality so that it favours an earliest access to autonomy the transsexual is able to prove. In regard of a psychological view (in opposition with a surgical view), this autonomy could be researched before the body transformation, validating the "Real Life Test" experience. [less ▲]

A full discontinuous Galerkin method is used to predict the fracture of beams thanks to insertion of an extrinsic cohesive element. In fact, The formulation developed originally by G. Wells etal. to guarantee weakly the high order derivatives of plates with only displacement field unknown and extended by L. Noels etal. for shells is derived for beam with full discontinuous elements. This new formulation can be advantageously combined, as shown first by J. Mergheim etal. , with an extrinsic cohesive approach as there is no need to modify dynamically the mesh, which is the major drawback of this approach. The pre-fractured stage is modeled by full discontinuous elements in a manner which is proved stable and consistent and the fracture is modeled by a cohesive law applied on stress resultant an stress couple defined by J.C. Simo etal. The suggested study produces two type of results. On one hand, it is shown analytically and verified by numerical examples that the presented framework has got the properties of consistency and convergence expected for a numerical scheme. On the other hand, it is proved by some test cases that the energy released during fracture process is equal to the fracture energy except in the case where the difference of internal energy between not fractured and fractured configurations is bigger than the fracture energy. In this case, the fracture occurs in one time step. The presented work proposed a novel interesting manner to take into account fracture in thin bodies. The verification made on the particularized case of beams suggested great perspectives for plates and shells which allow to simulate more complex problems. [less ▲]
