Context: In a recent work, we tried to obtain a calibration of the two components of the pre-main sequence binary system RS Cha by means of theoretical stellar models. We found that the only way to reproduce the observational parameters of RS Cha with standard stellar models is to decrease the initial abundances of carbon and nitrogen derived from the GN93 solar mixture of heavy elements by a few tenths of dex. Aims: In this work, we aim to reproduce the observational properties of the RS Cha stars with stellar evolution models based on the new AGS05 solar mixture recently derived from a three-dimensional solar model atmosphere. The AGS05 mixture is depleted in carbon, nitrogen and oxygen with respect to the GN93 mixture. Methods: We calculated new stellar models of the RS Cha components using the AGS05 mixture and appropriate opacity tables. We sought models that simultaneously satisfy the observations of the two components (masses, radii, luminosities, effective temperatures and metallicity). Results: We find that it is possible to reproduce the observational data of the RS Cha stars with AGS05 models based on standard input physics. From these models, the initial helium content of the system is YË 0.255 and its age is Ë 9.13 ± 0.12 Myr. [less ▲]

This book provides an analysis of bilateral tax treaties concluded by thirty-seven jurisdictions from five continents and empirically ascertains the impact of the UN and OECD Model Tax Conventions on bilateral tax treaties. It therefore fills a major gap in the international tax literature, which has so far either studied the sole Model Tax Conventions or focused on bilateral treaties in the context of the tax treaty policy of single countries, and sets the pace for a new methodology in the analysis and interpretation of tax treaties. A general report outlines the key points of the analysis, highlights current trends and predicts future developments of multilateralism and global tax law. This is an essential resource for academics, tax authorities and international tax practitioners who find textbooks based on Model Tax Conventions insufficient. • First study of tax treaties to adopt a global perspective • Demonstrates the impact of the OECD and UN Model Conventions via independent expert analysis and supplemented by a general report • Sets new standards for tax treaty interpretation by turning bilateral treaties into a possible core for developing multilateralism in global tax law [less ▲]

In order to gain a better understanding of non-agricultural pesticide use and to prepare the legislative and technical dossiers required under the Water Framework Directive, between October 2006 and March 2007, two surveys were conducted of 97 Walloon communes and 65 districts of the Walloon Ministry of Public Works and Transport (MET) (General Directorates for Motorways and Roads and for Waterway Infrastructure). The questionnaire (26 questions on six topics) was sent by e-mail or fax, with a response rate of 60 out of 97 communes and 33 out of 65 districts. This article describes the health-related aspects of the surveys (environmental aspects are the subject of separate article). The surveys have brought to light a number of bad practices and a growing awareness of the non-agricultural users with respect to health risks. However, bad habits, legislation infringements and a failure to follow good plant protection practice are still a problem and pose major health risks (which endanger the operator and the public). Information, awareness-raising and, especially, training of people therefore remain a priority for nonagricultural users. [less ▲]

This study describes the impact of the rulings of the European Court of Justice (respectively now the Court of Justice of the European Union) on Members States’ direct tax systems. It is the updated version (as of 31 December 2010) of the study PE 404.888 published in 2008. The case-law of the Court is characterised by its continuing development in a changing institutional, political, social and economic context. The area of taxation, and in particular the area of international taxation, is also an evolvingfield,in which conflicting or converging interests between states, or between states and taxpayers, play an important role in the shaping of the applicable national rules, which face new realities due to economic globalisation. Focusing on an analysis of the Court’s judgments, particular attention is also paid to major trends in the implementation of the Court’s case-law by Member States. Finally, the limits of the so-called 'negative integration' through the case-law of the Court are discussed and suggestions are made for possible further European action, notably the adoption of legislative acts in direct tax matters.

According to the dual-process models, recognition memory is supported by recollection and familiarity (Yonelinas, 2002). Familiarity is a complex function that depends on several processes. One of the most important mechanisms is the sense of familiarity driven by the fluency processing (Whittlesea, 1993). The fluency can be defined by the enhancement of processing speed and the ease of processing due to an earlier encounter with the stimulus. Our objective is to explore the effect on an increase of salience of fluency cues on the recognition memory performance of patients with Alzheimer disease (AD). Sixteen AD patients and sixteen healthy elderly controls (HC) performed two conditions of a memory task. In the study phase, 25 words were presented at a rate of one word every 1.5s. Participants were instructed to read the words aloud and to try and remember them. After a break of 5 minutes, participant performed a yes/no recognition task with 25 studied words and 25 new words. In the Non-Overlap condition, the 25 studied words were composed of a subset of letters of the alphabet and the 25 new words of the remaining letters. In the Overlap condition, the 50 words were based on the whole alphabet. The two recognition tasks were separated by a delay of 24h. The capacity to discriminate between old and new items was measured by the index d’. An ANOVA on d’ scores revealed that discrimination was poorer in the AD group than in the HC and also poorer in the Overlap condition than in the Non-Overlap condition. The current results showed that to increase salience of fluency at the level of letter by eliminating letter-overlap between old and new words increases the recognition performance to the same extent in both groups but the amplitude of AD memory deficit was not reduced (Bastin, Willems, Genon, & Salmon, 2013).

The thymus is the central lymphoid structure where T-cell differentiation takes place, and a crucial organ for the maintenance of homeostasis in the immune system. Thymopoiesis includes intrathymic proliferation of T-cell precursors, selection and output of both self-tolerant and competent effector T cells, as well as of natural regulatory T cells (nTreg). In the crosstalk between the neuroendocrine and immune systems, peptide hormones have been more and more implicated in immunomodulation for the last thirty years. The somatotrope growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis in particular has been repeatedly shown to play a major regulatory role upon thymus function and T-cell development. This review will focus on the important thymotropic properties of the somatotrope GH/IGF-1 axis, and will try to discriminate these properties in function of the endocrine or paracrine/autocrine pathways involved in their mediation. Most importantly, in light of an increasing number of recent studies, GH and IGF-1 now appear as a novel therapeutic agents that could be used for enhancing thymopoiesis in different cases of immune deficiencies, including aging-related immune dysfunction.

By using the regional climate model MAR (Modèle Atmosphérique Régional), validated for Greenland at 25km resolution and forced every 6 hours with the ERA-INTERIM reanalysis (Fettweis 2007, Fettweis et al. 2010), we have modelled the Greenland Ice Sheet (GrIS) Surface Mass Balance (SMB) at 20, 25, 30, 40 and 50km resolution to assess the impact of the spatial resolution. As part of the ICE2SEA project, the 25km-resolution SMB outputs of the MAR model are used as forcing fields for ice sheet models, in order to produce future projections of the GrIS contribution to sea-level rise over the next 200 years. Although the current spatial resolution of the MAR model (25km) is much higher than the general circulation models (GCM) resolution (150-300km), the ice sheet models often run at a higher resolution (typically 5-10km). Nevertheless, such higher-resolution runs of the MAR model on the same integration domain generate a significant additional computing time and are not doable until now. Moreover, conventional linear interpolations of the SMB outputs onto a higher-resolution grid, generally induce biases because ice sheet masks at different spatial resolutions do not match and the SMB is a very complex function of the spatial resolution and the topography . That is why several enhanced SMB interpolations are tested here in order to reduce biases when interpolating the MAR outputs onto higher resolution, in the framework of the ICE2SEA project. [less ▲]

This paper presents first results of a study that examines the impact of the workplace climate on workplace training effectiveness. Here training effectiveness is conceptualised in terms of transfer of training and the workplace climate is specified in terms of transfer climate. According to the theoretical framework by Carr, Schmidt, Ford and DeShon (2003), we hypothesise that the impact of the transfer climate on the transfer of training will be moderated and/or mediated by cognitive and affective states. Statistical analyses will be conducted to check the hypothesised mediating and moderating role of job satisfaction (affective state) and job engagement (cognitive state) between the transfer climate and the transfer of the newly acquired knowledge. Transfer climate has been broadly studied for its direct impact on transfer of training. The major issue of this study is to examine the interaction of the transfer climate with other variables In a longitudinal quantitative study, data are collected at the Belgian Sickness Fund. Participants are employees who took part to a training session between March and December 2010 (N=680). Right after the conclusion of the training program, each trainee is invited to fill the Learning transfer System Inventory (Holton, Bates, & Ruona, 2000), a scale measuring 16 dimensions of the transfer climate. One month later, participants are asked to fill a second questionnaire about their perception of the transfer (general and specific performance), job satisfaction (Price, 1977) and job engagement (Schaufeli & Bakker, 2003).

The interest in lignocellulosic substrates is increasing because they are clearly identified for their high potential of development in energy and value-added molecules production. Indeed lignocellulosic biomass constitutes a promising resource for a sustainable production of organic compounds and biobased products that could progressively replace molecules from the petrochemical industry. Until now lignocellulosic substrates were mainly used for the valorization of cellulose. Hemicelluloses and lignins were less valorized and often degraded after the process. However, due to their phenolic structure, lignins can be valorized in a lot of high-valued applications like vanillin production, replacement of petrochemical polymers, antioxidants for cosmetics and food industry, resins… In this study, a representative sample of beech wood (Fagus sylvatica L.) was collected in the region of Gaume in Belgium. Beech wood was delignified at atmospheric pressure by an organosolv process using a mixture of formic acid/acetic acid/water. The effect of cooking time and temperature was evaluated on the structure, physico-chemical properties and antioxidant activity of the lignins obtained from the black liquor after treatments. The structural and physico-chemical characteristics of the lignins were investigated with different tools like infrared spectrometry, thermogravimetric analysis, gel permeation chromatography after acetylation of lignins, NMR 1H, 13C and HSQC. The antioxidant activity was assessed by a spectrophotometric method using the α,α-diphenyl-β-picrylhydrazyl radical (DPPH). [less ▲]

The recycling of waste material produced by human activity is one of the challenges of our generation. One of the most serious environmental problems of the recent years is mass production of tire and the di􏰟culty of disposing of them. The material and energetic valorization of the wasted tires is possible through the extension of 􏰔green roads􏰕. The incorporation of crumb rubber from wasted tires in bi- tuminous binders allows the design of new asphalt pavements with a higher viscosity. A preliminary study to determine the impact of the use of crumb rubber modi􏰝ed bituminous binder in the sound generation level for a thin layer type BBTM11A, has been carried out by the LA2IC. These results are compared with sound level from a BBTM11A with a conventional binder. This work presents the acoustical characterization performed on the regional road CM-3102 in Ciudad Real (Castilla- La Mancha), based on the close proximity methodology (Tiresonic Mk4-LA2IC ). In addition, mea- surements of super􏰝cial macrotexture pro􏰝le have been realized with the LaserDynamicPG-LA2IC to study the relationship with close proximity road noise. Furthermore, sound absorption measurements of BBTM11A compacted samples have been analyzed to understand the mechanisms involved in the sound generation. The results show that addition of crumb rubber by the wet process leads, in this case (20% crumb rubber content), to a decrease in the sound level emitted by the interaction between tire and road surface, at low frequency by mu􏰠ing the vibrations and by sounf absorption at high frequency.
