Refractive solar concentrators suffer from important chromatic aberration. To enhance solar cell performance and increase the concentrating ratio, we propose an hybrid (diffractive/refractive) lens which allows a more uniform flux density and an achromatized (in the sense of achromatic doublet) illumination of the cell. To solve the problem of high diffraction efficiency, we turn to multilayer diffractive lenses to have broadband high diffraction efficiency optimized on solar spectrum. Rigorous coupled wave analysis simulations were performed in order to check the validity of scalar theory, they led to a new order of magnitude for the ratio period/wavelength which has been found to be around 100 in place of 10.

The Centre Spatial de Liège develops since 1993 holographic interferometry techniques and instruments based on photorefractive crystals for high resolution measurement of structures deformation, mainly for aerospace applications. In this paper we present the early results of development of a holographic technique and facility for deformation and expansion measurement of aerospace composites components. Here the holographic technique consists in using several illumination beams for retrieving different components of the displacement vector. In our case the components and structures to be measured in the future will undergo temperatures excursions up to 150°C typically. Since holographic techniques are sensitive to air turbulences, it is necessary to place the samples in a vacuum chamber. We will present some early examples of measurements with this facility, obtained for temperatures excursions ranged between ambient and 29°C as first steps before going further to higher temperatures excursions.

In complex scene, memory for central interest items is better than memory for marginal interest items and this difference remains stable independently of the scene presentation duration (Melcher, 2006). However, without eye movement recording, it is not possible to know whether central interest items are better remembered because they are more fixated or because they are more meaningful. In order to answer this question, we analysed the memory of complex scenes (paintings) according to the eye movements and subjects’ expertise. 15 novice subjects and 15 art historians (experts) were asked to look at 6 paintings that were separately and randomly presented for 10 seconds. After each painting presentation, subjects were asked questions about painting knowledge (author’s name, painting’s name) in order to evaluate their painting knowledge and about pictorial details of 3 categories: details of central or marginal interest and background information. If the expert and novice groups significantly differed concerning the knowledge they had about all paintings, the accuracy of answers about the painting details did not differ between both groups. Moreover, we showed novice’s answers were more accurate when they looked longer at the asked detail and when this detail was watched early on in the presentation while in the expert group, the accuracy of the answer was not influenced by the duration and moment they watched the asked detail. These findings suggest experts have some wrong representations which are not influenced by eye movements contrary to novices whom memory accuracy is influenced by their eye movements. [less ▲]

The dynamic response of electro-mechanically actuated micro structures is governed by nonlinear effects which directly influence their performance. To date, most work in the field of micro/nano systems is done experimentally and documented theoretical research consists of nonlinear lumped-mass models as well as continuum mechanics approaches. Existing and codified computational tools for micro-electromechanical systems (MEMS) more and more penetrate the market of designers and fabrication of such devices. The present work is the experimental part of a bench-mark study of a selected microbeam structure investigated with aforementioned analytical and computational techniques and compared to experiments performed with a Polytec MSA400 analyzer. The emphasis of this benchmark study is put on the nonlinear dynamic behavior with respect to qualitative and quantitative explanations of the electro-mechanical actuation and damping mechanisms.

Nowadays, compact sources relatively warm like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei can be investigated at milli-arcsecond scales only with the VLT in its interferometric mode. We propose a spectro-imager, named VSI (VLTI spectro-imager), which is capable to probe these sources both over spatial and spectral scales in the near-infrared domain. This instrument will provide information complementary to what is obtained at the same time with ALMA at different wavelengths and the extreme large telescopes. [less ▲]

La communication proposée offre l'analyse des conclusions d'une expérience de terminologie juridique bilingue menées au travers d'une double publication : un dictionnaire juridique bilingue (français - espagnol) de la Responsabilité civile et un ouvrage de synthèse sur la Terminologie et le Droit . Dans la ligne du titre du colloque, le Droit occupe un lieu significatif, puisque le problème d'intercompréhension qu'il pose consiste à établir les points d'équivalence possibles entre deux "mondes" (deux droits) par définition étrangers l'un à l'autre. Cette affirmation se fonde sur une analyse des domaines du savoir humain, orientée vers la démonstration de ce que le Droit entre, avec peu d'autres domaines, dans la catégorie de ceux qui n'ont pas de référent universel, ce qui, aux dires de certains, rend sa traduction prétendument impossible. Ensuite, la communication détaillera l'analyse des équivalences (et degrés de celles-ci) dont fait montre le dictionnaire cités ci-dessus, selon qu'il établit des catégories d'équivalence totale, d'équivalence partielle ou d'absence de toute équivalence possible. Cette analyse, avec tous les exemples illustratifs disponibles, cède alors le pas à plusieurs réflexions théoriques et conduit à proposer enfin une théorie de la traduction juridique :"qu'est-ce que traduire en droit?".

Graphical representations of power systems are systematically used for planning and operation. The coordinate systems commonly used by Transmission System Operators are static and reflect the geographical positions of each equipment of the system. We propose in this work to position on a twodimensional map the different buses of a power system in a way such that their coordinates also highlight some other physical information related to them. These pseudo-geographical representations are computed by formulating multidimensional scaling problems which aim at mapping a distance matrix combining both geographical and physical information into a vector of two-dimensional bus coordinates. We illustrate through examples that these pseudo-geographical representations can help to gain insights into the power system physical properties. [less ▲]

Chemical and/or physical modification of oils and fats are commonly used by food industry to widen their range of applications (1,2). Lipase-catalysed interesterification of anhydrous milk fat (AMF) and various vegetable oils is now a well documented procedure (3-7). The purpose of this technique is to produce original structured fats with properties different from a simple blending, that may be used as spreads or introduced into pastry. The new fats contain higher amounts of polyunsaturated fatty acids (PUFA) than butter, which provides health benefits (8,9). To our knowledge only a few authors associated AMF fractionation with blending and interesterification (10,11), although this combination may be used to increase the ratio of vegetable oil in blends and thus the PUFA content of the product. The compositional changes occurring during the lipase-catalysed interesterification of AMF/rapeseed oil (RO) and AMF stearin fraction (AMFSF)/RO blends were described in the first part of this study. In the present and second part are reported the resulting changes in physical properties, especially the melting behaviour through solid fat content (SFC), dropping point (DP) and fusion profiles by differential scanning calorimetry (DSC).

For many years, the Strasbourg Manuscript was believed to be the oldest German-language source for the study of Northern European painting techniques. Unfortunately, the manuscript was lost in the 1870 fire at the Strasbourg Library, and the text only survives in a 19th-century transcription made for Eastlake (1847). Studies such as those of Ploss and more recently those of Oltrogge have already highlighted the existence of texts with very similar contents, grouping them under the name of the ‘Strasbourg family’. Since these studies, a clearly defined corpus of manuscripts has been established as belonging to this family. This paper shows the different degrees of connection between the texts and presents some suggestions concerning their compilation process. The possibility of collating different versions of an identical text and cross-checking recipes can also be exploited to learn more about the ways in which recipe books were compiled, and to provide information concerning their use and function.

The present study describes the phytochemical profile Antioxidant and cytotoxicity activity of Lavandula dentata essential oil, collected in eastern Morocco (Taforalt). The sample of essential oil was obtained from the aerial parts of the plant by hydrodistillation and analyzed by GC–MS. The in vitro cytotoxicity of the oil on the cancer cell lines PC-3 (prostate), V79 (fibroblaste) and normal P388D1 (murine macrophage) was examined. We have shown that the oil had negligible cytotoxic effects against all cell lines tested. The oil was also found to possess antioxidant activity as demonstrated by the 1,1-diphenyl-2- picrylhydrazyl (DPPH) radical method. Lavandula dentata essential oil has promising potentials for incorporation into various food, cosmetic and pharmaceutical products for which a natural aroma, colour, antioxidant and antimicrobial additive is desired.

A time-domain extension of the classical frequency-domain thin-shell approach is used for the finite-element analysis of a shielded pulse-current induction heater. The time-domain interface conditions at the shell surface are expressed in terms of the average (zero-order) instantaneous flux and current density vectors in the shell, as well as in terms of a limited number of higher-order components. The three-dimensional thin-shell model is validated by comparing the numerical results with measurements performed on the heating device at different working frequencies. [less ▲]

Heaves is a common cause of recurrent airway obstruction (R.A.O) that occurs in mature horses stabled in a dusty environment. The long pentraxin PTX3 play an important role in the host defence and over-expression of PTX3 may contribute to airways injury. Therefore, we hypothesised that PTX3 may have relevance in the understanding of the pathogenesis of recurrent airway obstruction (R.A.O). In the present study, we first investigated the equine PTX3 (ePTX3) structure by cloning, sequencing and western-blotting. A 120pb deletion was found in the second exon of ePTX3 in comparison to human PTX3. Moreover, an alternative splicing occurs with complete deletion of the second exon, resulting in two forms of the protein, “spliced” (32 kD) and “full length” (42 kD). The pentraxin domain is very well conserved in the two forms with 94% of amino-acids conserved between equines and humans. These findings could have implications for the comprehension of the function of each domain of the protein. Then, we studied the effects of dust exposure and subsequent R.A.O crisis on ePTX3 expression in the broncho-alveolar lavage fluid (BALF) and the bronchial epithelial cells. PTX3 could be detected in BALF macrophages, neutrophils, eosinophils and bronchial epithelial cells. It was over-expressed in the BALF supernatant from RAO-affected horses in crisis. Dust exposure induced PTX3 in BALF macrophages either in healthy horses or in R.A.O-affected horses. Conversely, PTX3 was strongly over-expressed in the bronchial epithelial cells from R.A.O-affected horses in crisis. Considering epithelial cells as one of the major cell types in the airways, PTX3 produced at this level may play an important role in inflammatory process. Moreover, it suggests that dust-induced expression of PTX3 is differentially regulated in macrophages and bronchial-epithelial cells. A JNK-dependant, NFκB-independent regulatory pathway has been described in lung epithelial cells. A comparable mechanism could be involved in bronchial epithelial cells. If this is confirmed, PTX3 expression in respiratory epithelial cells could be therapeutically targeted. [less ▲]

Recent studies suggested that fear-related stimuli (such as spiders or snakes) are prioritized during visual selection. However, it remains unclear whether such stimuli capture attention in a bottom - up fashion when they are irrelevant for the search task. To investigate this issue we used the additional singleton paradigm (Theeuwes, 1992 Perception & Psychophysics 51(6) 599 - 606), in which participants had to search for a shape singleton (a circle among diamonds) while either a fear-related stimulus (a spider) or a fear-unrelated stimulus (a butterfly) was also present in the display. To determine whether the capture was modulated by the degree of actual fear evoked by the stimuli we compared performance of participants that scored high or low on the Fear of Spiders Questionnaire (Szymanski and O'Donohue, 1995 Journal of Behavior Therapy and Experimental Psychiatry 26 31 - 34). Results indicate that both task-irrelevant spiders and butterflies capture attention. More importantly, however, for high-fear participants the interference caused by spiders was larger than that caused by butterflies, signifying the role of fear as a factor in the capture of attention by fear-related objects.

The rising prevalence of obesity within both industrialized and emerging societies is a major public health problem. Indeed obesity is a usual risk factor in the development of metabolic and cardiovascular diseases which nowadays rank among the highest causes of premature death. Therefore, modulating fat mass expansion represents a worldwide challenge. In this context, adipocyte differentiation, which corresponds to the cellular transition of a fibroblastic cell (the preadipocyte) to a highly specialized cell accumulating triglycerides (the adipocyte), is a decisive process in the expansion of adipose tissue during life span and consequently, in the development of obesity. Adipogenesis markers such as PPARg2, C/EBPa, lipoprotein lipase (LPL), perilipin (PLIN) and the adipokines (leptin and adinopectin) are known to be expressed throughout the different stages of adipocyte differentiation. Guggulsterones are the principal bioactive steroidal components found in the oleoresin (guggul gum) collected from the indian guggul tree, Commiphora mukul (Hook, ex Stocks) Engl. The objective of this study was to investigate the effects of the two purified diastereoisomeric forms of guggulsterones (Z- and E-) on the human preadipocytes proliferation and differentiation.

Thermal variability of the coefficient of the critical state, or the angle of internal friction is examined in view of experimental results obtained for clays and hard rocks. This sensitivity has several implications for the evolution of what is considered as apparent preconsolidation pressure in constant stress heating tests. Failure conditions in soils at elevated temperatures appear to be strongly dependent on the history of application of stress and temperature, and hence are affected by the thermal sensitivity of the internal friction angle. Consequences to ranges of admissible processes are discussed. [less ▲]

In this paper, daily traffic counts are explained and forecasted by different modeling philosophies, namely the ARIMAX and SARIMA(X) modeling approaches. Special emphasis is put on the investigation of the seasonality in the daily traffic data and on the identification and comparison of holiday effects at different site locations. To get prior insight in the cyclic patterns present in the daily traffic counts, spectral analysis provides the required framework to highlight periodicities in the data. Data originating from single inductive loop detectors, collected in 2003, 2004 and 2005, are used for the analyses. Four traffic count locations are investigated in this study, an upstream and downstream traffic count location on a highway that is excessively used by commuters and an upstream and downstream traffic count location on a highway that is typified by leisure traffic. The different modeling techniques pointed out that weekly cycles appear to determine the variation in daily traffic counts. The comparison between seasonal effects and holiday effects at different site locations revealed that both the ARIMAX and SARIMAX modeling approach are valid frameworks for the identification and quantification of possible influencing effects. The technique yielded the insight that holiday effects play a noticeable role on highways that are excessively used by commuters, while holiday effects have a more ambiguous effect on highways typified for their leisure traffic. Modeling of daily traffic counts on secondary roads, and simultaneous modeling of both the underlying reasons of travel and revealed traffic patterns, certainly are challenges for further research.

Previous research has shown that the individuals suffering from emotional disorders have specificity of autobiographical memory (AM) deficits. This difficulty to remember specific personal past events seems related to difficulty to project specific oneself into the future (D’Argembeau, Raffard & Van der Linden, 2008). The aim of this study was investigated these impairments in population with bipolar disorders (BD). Participants (19 patients with bipolar disorders and 17 healthy subjects) completed validated French versions (Neumann & Philippot, 2006) of the AMT Williams & Broadbent (1986). Participants were instructed to generate specific past and future memories in response to cues words. For past events, the analyses revealed a significant group by memory interaction (F(2,68) = 4.0 ; p=.023) which indicates that the patients with BD recollected less specific events and more overgeneral events than controls. In the same way, for the future events task, a significant group by memory interaction emerged (F(2,68) = 7.85 ; p<.001) which indicates that the patients with BD were less specific and yielded more overgeneral memories than the control group. Thereby the results are consistent with previous studies that have examined autobiographical memory specificity in patients with BD (Scott et al., 2000; Mansell & Lam, 2004). However, to ours knowledges, the present study is the first to investigate specificity of AM and the abilities to generate specific events for future in patients with bipolar disorders. [less ▲]

This paper presents results from measurements of the magnetization, specific heat and dielectric constant, and their temperature and magnetic field dependence, for HoMnO3 single crystals. The results are discussed in the framework of existing data on magnetic symmetries and the interactions between the Mn-spins, the rare earth moments, and the lattice. From the resulting data, the magnetic phase diagram of HoMnO3 was built. [less ▲]
