Microarray technology is a miniaturized biotechnological tool with potential applications for study and analysis of multiple molecular compounds as proteins, lipids, carbohydrates or nucleic acids. The nucleic acids microarray technology focuses interest of scientists for fifteen years because of its huge potential as regard to the scientific research, clinical diagnosis, and development of new drugs. Only DNA microarrays are investigated in this paper. Born from the conjunction of micro-electronics, biochemistry, molecular biology, and image processing, microarrays allow to analyse several thousands of genetic information simultaneously. Thanks to this new tool, it is possible in parallel to identify, to even proportion, a considerable number of nucleic acid sequences contained in a biological sample (blood, biopsy, water, food, etc). This article proposes, after having considered the operating mode of the microarrays, to understand their quality standards as well as their advantages and disadvantages. The two following parts are devoted to the place the microarrays occupy in scientific research and in the establishment of a clinical diagnosis. Finally the last part evaluates prospects the microarrays offer in veterinary sciences. [less ▲]

Many CAD tools already allow to create and manipulate directly ideas in a digital way. However, designers still use the pen and paper technique during the early design phase of their projects. Indeed, existing CAD tools con-straint the creative work. There is a need for a sponta-neous human computer interaction in design computing. In order to answer to this need, we develop an integrated aided design tool based on an Virtual Desktop. The de-signer sits in front of a classical desktop where s/he can create and manipulate drawings and generated models. The paper relates the observations made from an ex-periment about the use of the Virtual Desktop by a de-signer. That experiment demonstrates that the immersive aspect of our system interface modifies the relation exist-ing between the designer and his/her model and, this way, its generates a new type of augmented interaction.

Within a multidisciplinary team of designers, architects and mechanical engineers, and ergonomists, we participate in a research project (ICC) in design and creative interface. This paper describes a participative and iterative approach and reviews the results of field studies involved in the design of a portable tool for finalizing freehand drawings. The results are discussed in terms of Activity Theory and its contribution to this field. [less ▲]

Les problèmes à la frontière belgo-allemande après 1945 font partie de ces épisodes oubliés de l'histoire des deux pays. Sur base d'une dcoumentation étoffée provenant d'archives belges et allemandes, cet article se propose de mettre en évidence la place de cette "question frontalière" dans le cadre de la politique belge à l'égard de l'Allemagne. Elle y est vue comme un indicateur des relations entre la Belgique et son grand voisin vaincu. Quels sont les projets de revendications territoriales aux dépens de ce dernier? Quels sont les acteurs derrière ces projets? Quel est le rôle du gouvernement belge? Et quelles sont les réactions des "concernés", de part et d'autre de la frontière? Telles sont les questions principales auxquelles l'article tente de répondre. [less ▲]

Some recent developments in the study of light and heavy pentaquarks are reviewed, mainly within constituent quark models. Emphasis is made on results obtained in the flavor-spin model where a nearly ideal octet-antidecuplet mixing is obtained. The charmed antisextet is reviewed in the context of an SU(4) classification.

We use the $1/N_c$ expansion of QCD to analyse the spectrum of positive parity resonances with strangeness $S = 0, -1, -2$ and -3 in the 2--3 GeV mass region, supposed to belong to the $[\textbf{56},4^+]$ multiplet. The mass operator is similar to that of $[\textbf{56},2^+]$, previously studied in the literature. The analysis of the latter is revisited. In the $[\textbf{56},4^+]$ multiplet we find that the spin-spin term brings the dominant contribution and that the spin-orbit term is entirely negligible in the hyperfine interaction, in agreement with constituent quark model results. More data are strongly desirable, especially in the strange sector in order to fully exploit the power of this approach. We discuss possibilities of extending the calculations to other excited baryons belonging to the N=2 or the N=4 band. [less ▲]

BACKGROUND: The most common human prion disorder is Creutzfeldt-Jakob disease (CJD); it includes sporadic, familial, iatrogenic, and variant subtypes. Diagnostic tests aim at detection with the highest specificity of very small deposits of abnormal prion protein (PrP). METHODS: We used immunoquantitative PCR (iqPCR) to detect proteinase K-resistant PrP (PrPRes) in tissue from the middle frontal gyrus of 7 patients with sporadic CJD and 7 non-CJD cases. We compared iqPCR with routine optimized ELISA, Western blotting, and immunohistochemical analyses. RESULTS: The 4 methods showed similar 100% sensitivity and specificity for the diagnosis of CJD. Along with high specificity, however, iqPCR had a threshold for PrP(Res) detection at least 10-fold lower than that of the classic ELISA. CONCLUSIONS: iqPCR is a new method for PrPRes detection that combines 100% specificity with a detection threshold at least 10-fold lower than classic techniques. This method may improve the detection of minute PrPRes deposits in tissues and body fluids and thus be useful for diagnostic and sterilization applications. [less ▲]

The Sahara and its margins largely contribute to the global injection of mineral dust into the northern hemisphere, about half of the yearly global mineral dust production. In this study, we have placed a pyramidal receptacle in Mâle (southern Mauritania) during the rainy season 2005 in order to measure daily Saharan dust deposition. The dust quantity collected totals 78.38 g/m2 during the 3 months experimented. Comparing our results to previous works achieved in the southern border of the Sahara shows that the levels of deposition in Mâle are extremely high. This could suggest a continuous environmental degradation resulting from always increasing human pressure. [less ▲]
