In this paper, we discuss ways of promoting a spatial data infrastructure (SDI). Further considerations regulating the organizational infrastructure, the development of tools and models taking into account the diversity of actors is inevitable to achieve the objectives of an SDI. Our study focused on the technical prerequisites for the establishment of an SDI in Morocco. An ontological approach to the reference spatial data has facilitated the definition of object types when cataloging reference entities, as well the concepts used in conceptual modeling. A feature catalog complying with ISO 19110 is developed using the principles of this ontology illustrating the independence and complementarity of object types, their adaptability to specific application domains and their inheritance. This approach allows establishing a reference model, that is to say a base structure which can be adapted to a wide range of applications. Developments of this work aim to sensitize policy makers about the introduction of an SDI in Morocco. [less ▲]

Variation at the pleiomorphic adenoma gene 1 (PLAG1) locus has recently been implicated in the regulation of stature and weight in Bos taurus. Using a population of 942 outbred Holstein-Friesian dairy calves, we report confirmation of this effect, demonstrating strong association of early life body weight with PLAG1 genotype. Peripubertal body weight and growth rate were also significantly associated with PLAG1 genotype. Growth rate per kilogram of body weight, daily feed intake, gross feed efficiency and residual feed intake were not significantly associated with PLAG1 genotype. This study supports the status of PLAG1 as a key regulator of mammalian growth. Further, the data indicate the utility of PLAG1 polymorphisms for the selection of animals to achieve enhanced weight gain or conversely to aid the selection of animals with lower mature body weight and thus lower maintenance energy requirements.

Ultrasound techniques allow examination of some parts of the suspensory ligament (SL) but "anomalies" are regularly observed. Their significance is not known. Few studies have described the relationship between ultrasonographic appearance and the exact morphology in histological sections. The aim of this study is to develop good techniques for cutting, staining, and showing the variation in the tissue composition within the SL. The SLs from the right limbs of 11 horses were collected. Samples were taken from cross-sections at six levels of the SL and they were embedded in paraffin or in Tissue-Tek®. Most of the paraffin sections were shredded. By using the cryosection technique, some freezing artifacts (holes) appeared. Therefore, a technique of freezing with cryoprotection was carried out, which produced the best results. Hematoxylin-phloxine-saffron gives a good contrast of colors between the tissues observed allowing the use of an image analysis program. The percentage of each tissue within the SL for each section and for six levels of the ligament was calculated. Results were analyzed by SAS software. The muscle tissue (PMT) and adipose tissue (PAT) decreased significantly (p < 0.0001), whereas the connective tissue (PCT) increased significantly (p < 0.0001) with age and when descending from the proximal to the distal level of the SL. The PMT was significantly higher (p < 0.0001) in females than males, while the PCT was significantly higher (p < 0.0001) in males than females. The PAT was significantly higher (p = 0.0278) in hindlimbs than in forelimbs. [less ▲]

Space electronic systems employ enclosures to shield sensitive components from space radiation. The purpose of shielding is to attenuate the energy and the flux of ionizing radiation as they pass through the shield material, such that the energy per unit mass (or dose) absorbed in silicon is sufficiently below the maximum dose ratings of electronic components. The received radiation amount varies significantly depending on several variables that include mission parameters (orbit, altitude, inclination and duration), spacecraft design (spacecraft wall thickness and panel-enclosure location). To achieve the optimum shielding with the minimum weight, all these variables have to be considered in the design. Energetic particles, mainly electrons and protons, can destroy or cause malfunctions in spacecraft electronics. The standard practice in space hardware is the use of aluminium as both a radiation shield and structural enclosure. Composite structures show potential for significant mass savings. However, conventional graphite epoxy composites are not as efficient shielding materials as aluminium because of their lower density, that is, for the same mass, composites provide 30 to 40% less radiation attenuation than aluminium. A solution is to embed high density (atomic weight) material into the laminate. This material, typically metallic material, can be dispersed in the composite or used as layers in the laminate (foils). The main objective of the “Radiation Shielding of Composite Space Enclosures” (SIDER) project is the development of the technologies and tools required to obtain lightweight, safe, robust and reliable composite structures. Two different strategies are being analysed as alternatives for radiation shielding: and he incorporation of a high density material foil. This paper will present and analyse the radiation shielding obtained by the incorporation of nanomaterials in composite structures. [less ▲]

The present article aims at pinpointing the issues involved in the analysis of the economy of ‘primitive’ societies carried out by Deleuze and Guattari in Anti-Oedipus by relying on a logic of debt (Nietzsche) rather than on a logic of reciprocity (Lévi-Strauss). Deleuze and Guattari’s critical discussion of Lévi-Strauss’s ethnology should related to the problematization of kinship as a system of alliance and filiation relationships suggested by French Marxist anthropology (E. Terray, C. Meillassoux) on the one hand, and to Edmund Leach’s critical anthropology on the other. This double mediation helps to show that in Anti-Oedipus, Deleuze and Guattari seek to identify the political strategies which are at work in economic relationships, that is to say, in the present case, the finite alliance strategies in ‘primitive’ societies, which are deeper than trade and production relationships.

Objectif : Etudier l’expression de KISS1 (métastatine) et de son récepteur KISS1R lors de la grossesse normale et pathologique. Matériels et méthodes : Nous avons étudié la localisation de KISS1 et KISS1R par immunohistochimie dans des placentas normaux (1 er et 3 ème trimestre). Par RT-PCR quantitative, nous avons évalué le niveau d’expression des ARNm dans les placentas et les lits placentaires correspondants. Les niveaux d’expression de ARNm ont été comparés entre les grossesses normales (GN, n=13) et les grossesses spathologiques Prééclampsiques -PE-, n=17 et retard de croissance intrautérine -RCIU-, n=9). Résultats : Au premier trimestre des GN, KISS1 est majoritairement localisé dans les syncitiotrophoblastes, alors que KISS1R est détecté dans le mesenchyme villositaire. Au cours du troisième trimestre, KISS1 est uniquement localisé dans le syncitiotrophoblaste au contact avec la décidue et dans le mésenchyme villositaire et KISS1R est détecté dans le trophoblaste extra-villeux ainsi que dans quelques cellules de la décidue. Les analyses par RT-PCR mettent en évidence une expression plus importante des ARNm de KISS1 (p<0,001) et de KISS1R (p=0.039) dans les placentas (GN,PE et RCIU) par rapport aux lits placentaires correspondants. Les niveaux d’expression de KISS1 et KISS1R ne sont pas, cependant, significativement modulés dans les grossesses pathologiques. Conclusions : Par immunohistochimie, nos résultats indiquent une expression spatiotemporelle différente pour KISS1 et KISS1R entre le 1 er et 3 ème trimestre des grossesses normales. Nous n’avons pas mis en évidence de modulation de l’expression des ARNm dans les grossesses pathologiques. [less ▲]

The EUV high resolution imager (HRI) channel of the Extreme Ultraviolet Imager (EUI) on-board Solar Orbiter will observe the solar atmospheric layers at 17.4 nm wavelength with a 200 km resolution. The HRI channel is based on a compact two mirrors off-axis design. The spectral selection is obtained by a multilayer coating deposited on the mirrors and by redundant Aluminum filters rejecting the visible and infrared light. The detector is a 2k x 2k array back-thinned silicon CMOS-APS with 10 µm pixel pitch, sensitive in the EUV wavelength range. Due to the instrument compactness and the constraints on the optical design, the channel performance is very sensitive to the manufacturing, alignments and settling errors. A trade-off between two optical layouts was therefore performed to select the final optical design and to improve the mirror mounts. The effect of diffraction by the filter mesh support and by the mirror diffusion has been included in the overall error budget. Manufacturing of mirror and mounts has started and will result in thermo-mechanical validation on the EUI instrument structural and thermal model (STM). Because of the limited channel entrance aperture and consequently the low input flux, the channel performance also relies on the detector EUV sensitivity, readout noise and dynamic range. Based on the characterization of a CMOS-APS back-side detector prototype, showing promising results, the EUI detector has been specified and is under development. These detectors will undergo a qualification program before being tested and integrated on the EUI instrument. [less ▲]

The 21st century is rich in mutations regarding veterinary medicine; society has never been so far from farm animal practices in industrialized countries, and so demanding in developing nations for a continuous milk and meat production. Meanwhile, even this great distance in northern nations between agriculture and society, our work has never been so much analyzed for its potential risk on human health and production quality. As health is now globalized, following trade and science, exchange could be the source of several pathological emergences. Focusing on animal health, our responsibility toward “larga manu” use of antibiotics has been identified and criticized. This situation is also happening in a time where, nevertheless our industrialization of agricultural production, ancillary exams are still expensive, and most of the time non valuable regarding a common cattle practice time schedule. So yes, we are mainly still experiencing empirical use of antibiotics like our pairs did, back several decades before. Yet, there exists nowadays many tools to analyze whether our practice could be considered as harmful to humanity survival and good use of priority antibiotics. We therefore have to reconsider our practice of Antibiotherapy, regarding these new challenges and find new ways for medical management of infectious diseases. [less ▲]

In the wake of Richards Benton’s “Keats and Zen” (published in Philosophy East and West (1966)), this paper sets out to examine Janet Frame’s appropriation of Buddhist philosophy in Snowman, Snowman (1962). The novella’s allusions to a Buddhist-like epistemology, together with its subtle references to Scandinavian myths, however, have so far remained uncovered and are therefore best approached in the light of what has been called “the suppressed intertextuality in post-colonial writing”. The author’s intention in this paper is twofold: On the one hand, the author will suggest that post-colonial writers do not necessarily write against the Western canon and that maintaining the contrary amounts to vindicating the centrality of imperial texts in the contemporary literary scene—an endeavour which is hardly post-colonial. On the other hand, the author will go some way towards shifting eastward the core of Frame’s ontology by suggesting that her poetics is anchored not only in Western thinking, but also, perhaps more importantly so, in Eastern philosophy. The author’s primary impulse, however, in examining the interplay between canonical and peripheral intertextualities, is to illuminate in fundamental fashion the haunting beauty of the writer’s universe and the lyricism of Snowman, Snowman.

In Europe, farmers have to manage larger herds but, at the same time, want to have a normal social life. So, the automatic milking system (AMS) can bring solutions. This technology implies in most cases, the cessation of grazing although grazing is appreciated by the consumers who consider it to be a natural practice. At the experimental farm of the University of Liege, the concept of a mobile milking robot has been developed with a private company. The prototype is used indoors during the winter season and is moved outdoors during the grazing season in pastures romote from the farm. [less ▲]
