In this paper, some algorithmic and computational advances are presented for power system dynamic simulations. The heart is a Schur-complement-based solution algorithm, stemming from domain decomposition methods, applied to the differential-algebraic equation model. This algorithm is then accelerated computationally, by employing parallel computing techniques, and numerically, by exploiting time-scale decomposition and localization. Models of a real medium-scale system and a realistic large-scale test system are used for the performance evaluation of the proposed methods. [less ▲]

Currently, it is difficult for a student to pursue higher education without using a digital environment. This leads to the emergence the concept of Personal Learning Environment (PLE). The authors define it and consider his competition or complementarity with the digitals institutional environments. They report exploratory study results on students’ representations about their numeric learning environments and their interests about them. Data comes from questionnaires and interviews. Their analysis shows different profiles related to the PLE. Linking the results to learning theories and aspects of technical and educational design, they propose further investigation and development related to the complementarity of PLE and institutional learning environments (ILE).

Thiamine triphosphate (ThTP) was discovered over 60 years ago and it was long thought to be a specifically neuroactive compound. Its presence in most cell types, from bacteria to mammals, would suggest a more general role but this remains undefined. In contrast to thiamine diphosphate (ThDP), ThTP is not a coenzyme. In E. coli cells, ThTP is transiently produced in response to amino acid starvation, while in mammalian cells, it is constitutively produced at a low rate. Though it was long thought that ThTP was synthesized by a ThDP:ATP phosphotransferase, more recent studies indicate that it can be synthesized by two different enzymes: (1) adenylate kinase 1 in the cytosol and (2) FoF1-ATP synthase in brain mitochondria. Both mechanisms are conserved from bacteria to mammals. Thus ThTP synthesis does not seem to require a specific enzyme. In contrast, its hydrolysis is catalyzed, at least in mammalian tissues, by a very specific cytosolic thiamine triphosphatase (ThTPase), controlling the steady-state cellular concentration of ThTP. In some tissues where adenylate kinase activity is high and ThTPase is absent, ThTP accumulates, reaching ≥ 70% of total thiamine, with no obvious physiological consequences. In some animal tissues, ThTP was able to phosphorylate proteins, and activate a high-conductance anion channel in vitro. These observations raise the possibility that ThTP is part of a still uncharacterized cellular signaling pathway. On the other hand, its synthesis by a chemiosmotic mechanism in mitochondria and respiring bacteria might suggest a role in cellular energetics. [less ▲]

The Banzhaf power and interaction indexes for a pseudo-Boolean function (or a cooperative game) appear naturally as leading coefficients in the stan- dard least squares approximation of the function by a pseudo-Boolean func- tion of a specified degree. We first observe that this property still holds if we consider approximations by pseudo-Boolean functions depending only on specified variables. We then show that the Banzhaf influence index can also be obtained from the latter approximation problem. Considering cer- tain weighted versions of this approximation problem, we introduce a class of weighted Banzhaf influence indexes, analyze their most important properties, and point out similarities between the weighted Banzhaf influence index and the corresponding weighted Banzhaf interaction index. We also discuss the issue of reconstructing a pseudo-Boolean function from prescribed influences and point out very different behaviors in the weighted and non-weighted cases. [less ▲]

This study aimed at comparing data obtained from Azawak zebu colostrum with literature data. The comparison was performed by a meta-analytical approach. Colostrum samples were hand-collected after 5 h from 7 Azawak cows at calving between August 27, to September 10, 2009 in the Sahel. For data from literature, twenty one (21) references were identified in the following analytical databases: PubMed, Science Direct, Google scholar, Collection from University of Liege. The references were selected according to the following two criteria: i) only studies reported on bovine colostrum were used irrespective of breeds, and ii) among the selected studies, those not providing complete information to allow meta-analytical calculation were excluded. Samples were analyzed for immunoglobulins (IgG, IgM, IgA), lactoferrin, and chemical composition (dry mater, protein, fat, lactose, ash, Ca, P, NA, K, Mg). The mean levels of IgG, IgM, dry matter, protein and fat for Azawak cows were lower (P ˂ 0.001) than those obtained in other breeds; however colostrum from the Azawak was higher in IgA but the difference was not significant. For lactose and ash, mean values for Azawak cows were higher (P ˂ 0.001) than those from the literature. Contents of Ca, P, Na and Mg in Azawak bovine colostrum were significantly higher (P ˂ 0.001) than the mean levels in form the literature data. In conclusion, the colostrum from Azawak cows appears to be lower in most immunoglobulins, in fat and in protein than the values reported in the literature, but higher in lactose and minerals. This could be an adaptation to sahelian contraints. [less ▲]

Among all classes of drugs, the type 5 phosphodiesterase inhibitors (PDE5-i) (sildenafil, vardenafil and tadalafil) are the most counterfeited and copied in industrialized countries. This is why it is very important for regulatory agencies to have a panel of analytical methods to analyse these drugs and to be able to detect counterfeit or substandard medicines. During this chapter, several analytical techniques will be described and discussed. Among spectroscopic techniques, Raman, NIR, FT-IR and chemical imaging techniques will be envisaged. Their ability to detect counterfeits and predict if a new sample is genuine or not will be presented. Other techniques such as XRay powder diffraction and NMR spectroscopies will be briefly presented. Chromatographic impurity fingerprints will be considered and described for the analysis of suspect samples of Cialis® and Viagra®. Once again, the possibility to predict the authenticity of a new sample by the mean of this technique is envisaged. Finally, a MS-compatible UHPLC-UV method for the analysis of the three authorised PDE5-i and some of their analogues will be shortly described. This technique has been validated using spiked placebo samples in a vegetal matrix representing a suspect sample with a complex matrix. As a conclusion, a generic strategy for the detection and quality evaluation of counterfeit drugs will be presented. [less ▲]

La valorisation de l'expérience connaît un développement considérable, en particulier depuis les accords de Lisbonne concernant la Formation Tout au Long de la Vie (FTLV) dans les années 2000. Située au confluent de stratégies individuelle, organisationnelle, nationale et continuentale, la reconnaissance des apprentissages non formels et informels, dont les avancées diffèrent selon les états membres de l'UE, est au coeur des attentions. Pour mieux saisir le développement en Belgique francophone de la prise en compte de l'expérience des individus, le présent chapitre dresse le paysage des strucutures officielles permettant de valoriser voire valider les compétences acquises par les individus tout au long de leur vie.
