For six decades, between 1945 and 2005, Belgian officers and soldiers carried out part of their career or of their military service in Germany. Created as the Belgian Occupation Army, the name changed in the early 1950s to Belgian Forces in Germany, a symbolic name change that marked the beginning of an evolution during which the former enemy became a partner in the framework of NATO in 1955. The article focuses on the first years of this presence in Germany, when the memory of the Second World War and of the second occupation of Belgium by Germany was still fresh. It questions the representation of Germany and the Germans among the soldiers and the officers, but also among those who outlined Belgian military policies in Germany. It shows the “moral superiority complex” of many Belgians towards the defeated, but also towards the British ally who was suspected of being lenient towards the Germans and failed to understand their mentality. Furthermore, the relations between Belgians, British and Germans were conditioned by the Allied refusal to confer the political competences of the military government to the Belgians and by a unilateral British decision to extend the Belgian divisional area to Westphalia, two hundred kilometres east of the Rhine. The principal objective of the Belgian participation in the occupation, the guarantee of the Belgian interests with respect to the defeated Germany, then seemed impossible to reach. Two geographical areas are at the centre of the analysis : the border region, subject to claims of Belgian reparations, and the city of Cologne which the Belgian troops occupied at the expense of French aspirations on the Rhineland. The article also seeks to understand the very difficult introduction of a Belgian cultural propaganda, which illustrates the tense terrain of Belgian politicy towards Germany. If the government adopted a moderate position with regard to the reparations relatively early on, it maintained a hard line where the relations between Belgians and Germans were concerned, fearing a public opinion little disposed to accept a rapprochement. However, the reality on the ground often defied this attitude. [less ▲]

One of the most versatile methods to prepare TiO2 fine powders and films is the sol-gel technique. It offers many advantages, among which the possibility to control the stoichiometry, work in mild and ambient atmospheric conditions and achieve high purity and homogeneity of the final product. Stable TiO2 sols were synthesized by an aqueous sol-gel process using titanium tetraisopropoxide (TTIP) as precursor and nitric acid in water as hydrolyzing agent. The aim of the present study was to investigate the influence of different solvents and different amounts of HNO3 on the photocatalytic activity of TiO2 in the breakdown of ethanol (EtOH) as VOC molecule under UV and visible light. In particular, ethanol, isopropanol and butanol were used as solvents and two different molar ratios of HNO3 with respect to TTIP (0.25 and 0.5 respectively) were used. Their effect was investigated with regard to the photocatalytic properties of the films obtained by spin coating on sodium free glass [1] and heat treated at 450°C in air. The microstructure, optical and morphological properties of the films were investigated using SEM, UV-Vis spectroscopy and ellipsometry. The nature of the crystalline phases was ascertained by X-ray diffraction and the surface area of the powders was measured by N2 adsorption. The porous TiO2 films obtained show quite good photocatalytic activity for the degradation of EtOH compared to titania films prepared using P25 Degussa as shown in Fig. 1. Further the photocatalytic properties of the thin films obtained by aqueous sol-gel method were compared with the activity of films prepared using the same titanium precursor by a non-aqueous sol-gel process, in which the hydrolysis is initialized by esterification reaction between acetic acid and alcohol.

In experimental studies, the lack of statistical significance is often interpreted as the absence of an effect. Unfortunately, such a conclusion is often a serious misinterpretation. Indeed, non-significant results are just as often the consequence of an insufficient statistical power. In order to conclude beyond reasonable doubt that there is no meaningful effect at the population level, it is necessary to use proper statistical techniques. The present article reviews three different approaches that can be used to show the absence of a meaningful effect, namely the statistical power test, the equivalence test, and the confidence interval approach. These three techniques are presented with easy to understand examples and equations are given for the case of the two-sample t-test, the paired-sample t-test, the linear regression coefficient and the correlation coefficient. Despite the popularity of the power test, we recommend using preferably the equivalence test or the confidence interval. [less ▲]

In this study, a new method has been developed to produce pure crystalline BaZrO3 powders from Ba+Zr solution or weakly soluble reactants by using precipitation route in highly basic aqueous solution. The influence of several synthesis parameters is studied. At high OH- concentration ([NaOH] = 20 mol/l), it is possible to obtain the well-crystallized stoichiometric perovskite phase at relatively low temperature (~80°C), after a short reaction time (15 minutes) and without requiring any precaution to avoid the presence of CO2. This synthesis method yields spherical particles, whose size can be controlled by changing the concentration of the Ba+Zr solution. No calcination treatment is necessary since the precipitate is crystalline. Suitable choice of the synthesis parameters ([NaOH] = 20 mol/l, [Ba+Zr] = 1 mol/l, reaction time = 15 minutes) yields a sub-micron precipitate. [less ▲]

Alteration of early haematopoietic development is thought to be responsible for the onset of immature leukemias and lymphomas. We have previously demonstrated that Tax(HTLV-1) interferes with ss-selection, an important checkpoint of early thymopoiesis, indicating that human T-cell leukemia virus type 1 (HTLV-1) infection has the potential to perturb thymic human alphabeta T-cell development. To verify that inference and to clarify the impact of HTLV-1 infection on human T-cell development, we investigated the in vivo effects of HTLV-1 infection in a "Human Immune System" (HIS) Rag2(-)/(-)gamma(c)(-)/(-) mouse model. These mice were infected with HTLV-1, at a time when the three main subpopulations of human thymocytes have been detected. In all but two inoculated mice, the HTLV-1 provirus was found integrated in thymocytes; the proviral load increased with the length of the infection period. In the HTLV-1-infected mice we observed alterations in human T-cell development, the extent of which correlated with the proviral load. Thus, in the thymus of HTLV-1-infected HIS Rag2(-)/(-)gammac(-)/(-) mice, mature single-positive (SP) CD4(+) and CD8(+) cells were most numerous, at the expense of immature and double-positive (DP) thymocytes. These SP cells also accumulated in the spleen. Human lymphocytes from thymus and spleen were activated, as shown by the expression of CD25: this activation was correlated with the presence of tax mRNA and with increased expression of NF-kB dependent genes such as bfl-1, an anti-apoptotic gene, in thymocytes. Finally, hepato-splenomegaly, lymphadenopathy and lymphoma/thymoma, in which Tax was detected, were observed in HTLV-1-infected mice, several months after HTLV-1 infection. These results demonstrate the potential of the HIS Rag2(-)/(-)gamma(c)(-)/(-) animal model to elucidate the initial steps of the leukemogenic process induced by HTLV-1. [less ▲]

In this paper a low order partial hybrid stress solid-shell element based on the composite energy functional for the analysis of laminated composite structures is presented. This solid-shell element has eight nodes with only displacement degrees of freedoms, and three-dimensional constitutive models can be directly employed in the present formulation without any additional treatment. The assumed interlaminar stress field provides very accurate interlaminar stress calculation through the element thickness. These elements can be stacked on top of each other to model multilayer structures, fulfilling the interlaminar stress continuity at the interlayer surfaces and zero traction conditions on the top and bottom surfaces of the laminate. The present solid-shell does not show the transverse shear, trapezoidal and thickness locking phenomenon. [less ▲]

The detailed study of the nebulae ejected from Luminous Blue Variables and the circumstellar bubbles around Wolf-Rayet stars, which radiate strongly in the IR due to the heating of dust, is crucial for understanding the massive stars evolution. With Herschel, the largest telescope ever flown in space, we are able to study the gas and the dust in these circumstellar environments in the full far-infrared waveband. In the context of 'Mass-loss of Evolved StarS' Herschel guaranteed time key programme, we have obtained imaging and spectroscopic observations of nebulae associated with Luminous Blue Variable and Wolf-Rayet stars using PACS, one of the three instruments onboard Herschel. A description of these observations and first results of the data analysis are presented. [less ▲]

Since the beginning of research on the éperon barré of Pont-de-Bonne (Modave, Belgium), we have recovered artefacts attributed to the Middle Neolithic. More recently, during excavation of the entrance system of the fortification, a pot hole and a waste accumulation zone have been analysed. These structures contained abundant archaeological material (ceramic sherd, lithic and bone artefact and fauna). Three radiometric dates have been obtained. The ceramic assemblage is typical of the Belgian Michelsberg and a decorated vase shows Bischheim affinities. [less ▲]
