Paper presents and discusses data obtained in a testing program on the replacement of limestone powder in asphalt concretes by fly ashes. This would combine economic, environmental and technical benefits. The finest fly ash of Vietnamese origin scored best. This is proposed due to the gap-graded design of the particulate mixture of coarse crushed rock fractions, fine fluvial sand and the mineral admixture. The test program encompassed Marshall tests, creep tests and splitting tensile tests. [less ▲]

The closed-form solution to the problem of the relative motion in gravitational fields is expressed with the help of the universal functions. The full nonlinear model of the relative motion is considered, and no linearization or approximation assumptions are made. The results are free of singularities and they hold for any reference and targeted orbits, as well as for any time scale. A unified way to propagate the relative orbit with respect to time is introduced, by making use of the solution to a generalized Kepler equation. [less ▲]

A comprehensive analysis, together with the derivation of a closed form solution to the two-body problem in arbitrary non-inertial reference frames are made within the present work. By using an efficient mathematical instrument, which is closely related to the attitude kinematics methods, the motion in the non-inertial reference frame is completely solved. The closed form solutions for the motion in the non-inertial frame, the motion of the mass center, and the relative motion are presented in the paper. Dynamical characteristics analogue to the linear momentum, angular momentum and total energy are introduced. In the general situation, these quantities may be determined as functions of time, and their derivation is presented within the paper. In the situation where the non-inertial frame has only a rotation motion, these quantities become first integrals in a larger sense, with respect to an adequately defined differentiation rule.

Superconductors are known for the ability to trap magnetic field. A thermally actuated magnetization (TAM) flux pump is a system that utilizes the thermal material to generate multiple small magnetic pulses resulting in a high magnetization accumulated in the superconductor. Ferrites are a good thermal material candidate for the future TAM flux pumps because the relative permeability of ferrite changes significantly with temperature, particularly around the Curie temperature. Several soft ferrites have been specially synthesized to reduce the cost and improve the efficiency of the TAM flux pump. Various ferrite compositions have been tested under a temperature variation ranging from 77K to 300K. The experimental results of the synthesized soft ferrites-Cu0.3Zn0.7Ti0.04Fe1.96O4, including the Curie temperature, magnetic relative permeability and the volume magnetization (emu/cm3), are presented in this paper. The results are compared with original thermal material, gadolinium, used in the TAM flux pump system.-Cu0.3Zn0.7Ti0.04Fe1.96O4 holds superior characteristics and is believed to be a suitable material for next generation TAM flux pump. © 2011 IEEE.

In the case of sheet metal characterization, compression tests at normal direction of the sheet can be done by means of the layer compression test. Circular cylinder specimens are commonly used for compression test but the complicated layer alignment is time consuming and may induce a wrong anisotropy characterization. This final goal explains the interest of working on elliptic shape. In this article, an elliptical cylinder specimen is proposed and tested for bulk Titanium alloy. Full-field optical technique (3D Digital Image Correlation) is used for displacement measurements by means of three camera systems (Limess), which allows out-of-plane displacement/strain fields on around 300° of the specimen. The use of this technique easily provides accurate barreling profile used to compute Coulomb friction coefficient by using inverse method. [less ▲]

Het Zoniënwoud straalt ongereptheid uit, heeft een respectabele ouderdom en staat op een moeilijke ondergrond : deze factoren geven de statige beukenkathedraal iets kwetsbaars. Het bos lijdt onder de wind en is gevoelig voor hitte en droogte. Het evenwicht met zijn omgeving wordt hierdoor steeds wankeler en de bedreiging door de klimaatverandering gaat zwaarder wegen. Deze objectieve vaststelling kan verschillende reacties uitlokken : keuze voor een veel dynamischere bosbouw naargelang van de verjongingen, geleidelijke verrijking van het bos met soorten die beter gedijen in de toekomstige omstandigheden, zoals de wintereik, of evolutie naar een gemengd en ongelijkvormig hooghout dat beter bestand is tegen verstoring en dat het aanzicht van het Zoniënwoud drastisch zou wijzigen. De liefde voor de beukenkathedraal mag dan wel sterker zijn dan de rede, het is in elk geval nodig de aanplanting van beuken voor een tiental jaar op te schorten, minstens tot er meer zekerheid is over de wetenschappelijke voorspellingen.

We present recent developments on the role of the running coupling constant at the intersection of perturbative and nonperturbative QCD. A number of experiments show a smooth transition from small to large scales given by the four-momentum transfer in the reactions. This is at variance with perturbative QCD where the running coupling constant becomes infinite when the scale equals ΛQCD. Approaches using an effective coupling constant could help interpret the opposite trend of data as compared to standard perturbative QCD predictions. We give an overview of the role of the coupling constant in the procedure to match nonperturbative hadronic model to perturbative QCD and we propose an extraction of an effective coupling constant from inclusive electron proton scattering data at large Bjorken x.

Introduction La viscosupplémentation par injection intra-articulaire d’acide hyaluronique est recommandée dans le traitement de l’arthrose. Cependant, l’acide hyaluronique a une faible rémanence articulaire, ce qui limite son efficacité dans le temps. Dans ce travail, nous avons testé un nouveau biomatériau formé par le mélange de billes d’alginate-chitosane (AC) associées à un hydrogel visqueux synthétisé au départ de chitosane (H). Ce nouveau biomatériau breveté offre de nombreux avantages :1) biocompatible et non toxique, 2) composé exclusivement au départ de biopolymères d’origine non animale (chitosane et alginate), 3) les billes qui le composent sont élastiques, déformables et exercent un effet anti-inflammatoire et anti-catabolique sur les chondrocytes. Matériels et Méthodes L’arthrose a été induite chez le lapin HYLA albinos par la section du ligament croisé antérieur (LCA). Une semaine après l’intervention chirurgicale, les lapins ont été répartis dans trois groupes expérimentaux et ont bénéficié d’une injection intra-articulaire (900µl) des traitements suivants : billes AC associées à un hydrogel H (Groupe I ; n=7) ; hydrogel H seul (Groupe II ; n = 7) ; liquide physiologique (Groupe III ; n = 7). Des radiographies standards du genou en extension ont été réalisées avant l’intervention et pendant six semaines après l’intervention à raison d’une radiographie par semaine. Après 6 semaines de traitement, les animaux ont été euthanasiés et l’articulation prélevée. Une étude macroscopique du cartilage coloré à l’encre de Chine a été réalisée. Des coupes histologiques colorées à la Safranine-O/fast green provenant des zones portantes dans chaque compartiment ont été évaluées selon le score histologique de l’OARSI (Laverty et al., 2010). Résultats L’analyse des clichés radiologiques montrait une diminution significative (p<0,05) des signes radiologiques d’arthrose après 6 semaines dans le groupe I (billes AC + hydrogel H; 1,57 ± 0,2) en comparaison avec les groupe II (hydrogel H; 2,16 ± 0,47) et III (liquide physiologique ; 3,0 ± 0,43). La macroscopie révélait une tendance à l’amélioration de la taille et du grade des lésions dans le groupe I. La sévérité des lésions histologiques étaient significativement diminuée dans le groupe I (10,98 ± 0,72) par rapport au groupe II (14,43 ± 0,57 ; p<0,01) et au groupe III (14,79 ± 0,62 ; p<0,001). Cet effet était visible au niveau des condyles fémoraux et des plateaux tibiaux. Discussion L’injection intra-articulaire du mélange bille AC + hydrogel H est plus efficace que l’hydrogel H seul, ce qui suggère que les billes AC jouent un rôle dans l’efficacité de ce nouveau traitement. Cette nouvelle formulation pourrait être utilisée pour le traitement par viscosupplémentation de l’arthrose chez l’homme. Conclusion Le nouveau biomatériau formé par le mélange de billes AC et d’un hydrogel visqueux à base de chitosane prévient la progression de l’arthrose chez le lapin. [less ▲]

Methanol (CH3OH) is a key organic compound in the Earth’s troposphere, with reported concentrations of the order of a few ppbv. It is indeed the second most abundant organic atmospheric compound after methane (Jacob et al., 2005). The same authors have estimated its lifetime to a few days. Natural sources of CH3OH include plant growth, oceans, decomposition of plant matter, oxidation of methane,. . . They are complemented by anthropogenic (from vehicles, industry) and biomass burning emissions. Oxidation by the hydroxyl radical is the main sink, leading to the formation of carbon monoxide (CO) and formaldehyde (H2CO) (Rinsland et al., 2009; Stavrakou et al., 2011, and references therein). The first retrievals of methanol from ground-based Fourier Transform Infrared (FTIR) spectra have been reported by Rinsland et al. (2009), using spectra recorded at Kitt Peak (31.9ºN) and a microwindow extending from 992 to 999 cm-1. Soon after, Stavrakou et al. (2011) used another spectral interval from 1029 to 1037 cm-1, for methanol retrievals at Reunion Island (21ºS). In both cases, lines of the strong nu8 band of CH3OH were adjusted, accounting for interferences by several isotopologues of ozone and by water vapor. In this contribution, we will present first retrievals of CH3OH from observations recorded at the high-altitude station of the Jungfraujoch (46.5ºN, 8ºE, 3580 m asl), with a Bruker 120HR spectrometer, in the framework of the Network for the Detection of Atmospheric Composition Change (NDACC, visit http://www.ndacc.org). We will implement existing retrieval approaches –and possibly additional one(s)– to determine which strategy is the most appropriate for our dry high-altitude site. If successful, a long-term CH3OH total column time series will be produced using the Jungfraujoch observational database, and we will perform preliminary investigations to characterize the seasonal and inter-annual variations of this species at northern mid-latitudes.

We briefly describe the 1/Nc expansion method for studying baryon masses. Two approaches of the large Nc excited baryons have been proposed so far. The first one, based on the Hartree picture, treats the baryon as a ground state core and an excited quark and the second one, suggested recently, considers the baryon globally, without decoupling the system. The masses of excited states of mixed orbital symmetry of nonstrange and strange baryons belonging to the lowest [70, −] multiplet are calculated in the 1/Nc expansion to order 1/Nc with the new method which allows to considerably reduce the number of linearly independent operators entering the mass formula. The status of the resonance Λ(1405) is discussed. [less ▲]

The so-called "magnetic flux profile" AC inductive technique is a powerful method for determining the critical current density Jc of bulk superconductors. In this work we aim at reporting analytical expressions for magnetic flux profiles of superconducting rectangular samples exhibiting a critical current density anisotropy. The results are used for examining the error resulting from approximating a rectangular cross-section by an "infinite cylinder" or "infinite slab" geometry. It is found that such approximations can lead to an artificial curvature of the flux profiles and errors of 10%–20% in the determination of Jc. Next, the effects of how planar defects (cracks, platelet boundaries,...) affect the magnetic flux profile signal are discussed. It is found that the magnetic flux profiles are much sensitive to the lengthscale of shielding currents, thereby providing means of investigation of the typical size of induced current loops in bulk superconductors. Finally some illustrative flux profile data measured on a bulk, large grain melt-processed YBCO single domain exhibiting Jc anisotropy are presented and discussed in relation with theoretical predictions.

This communication deals with the question to know if this is possible to program a neural system with a language and a consciousness. There are several levels and categories of language, by example, verbal and non-verbal languages, signs language, etc. There are also several levels and categories of consciousness, by example, verbal consciousness, non-verbal selfconsciousness, and absence of consciousness with the a-consciousness. By a systemic approach, we extend the role of the brain to the whole neural ectoderm, including the nervous systems, the brainstem, the brain, and the skin that is the actual envelope of the brain to the environment. This paper will demonstrate that such a neural system can be programmed, on the basis of scientific research in experimental neurosciences and in artificial intelligence, extending de facto all the possibilities of learning of classical neural networks.

This article presents a systemic approach to the concept of natural intelligence with the aim of creating an artificial intelligence. Thus, the natural intelligence, human and nonhuman animals, is a function composed of faculties to know and understand. In addition, natural intelligence is inseparable from the structure, namely the organs of the brain and body. The temptation is to equip computer systems with artificial intelligence that should have a function composed of the same faculties as those encompassed in human intelligence. The artificial intelligence must also remain inseparable from the structure, namely the organs of an artificial brain and an artificial body. As a result, the artificial robot is the ideal structure to see the emergence of a strong artificial intelligence. Note that a weak artificial intelligence is developed on computer systems by a simulation program of intelligence. In this paper, neural programmable memories will be presented and simulated [less ▲]

Background: Organic dust contains pathogen associated molecular patterns (PAMPs) which can induce, following chronic exposure, significant airway diseases. Mononuclear phagocytes are key protecting cells of the respiratory tract. Several studies have investigated the effects of PAMPs, and mainly endotoxins, on cytokine production. However the sub-lethal cytotoxicity of organic dust components on macrophages has not been tested yet. The novel technology of high content analysis (HCA) is already used to assess subclinical drug-induced toxicity. It combines the capabilities of flow cytometry, intracellular fluorescence probes, and image analysis and enables to perform rapid multiple analysis in large numbers of samples. Objectives: The purpose of the present study was, by using HCA, to investigate the cytotoxicity of the 3 major PAMPs contained in organic dust, ie. endotoxin (LPS), peptidoglycan (PGN) and β-glucans (zymosan) on THP-1 monocyte-derived macrophages. Methods: LPS was used at concentrations of 0.005, 0.01, 0.02, 0.05, 0.1 and 1 μg/ml; PGN and zymosan were used at concentrations of 1, 5, 10, 50, 100 and 500 μg/ml. Cells were exposed to PAMPs for 24 hours. In addition, the oxidative burst and the phagocytic capabilities of the cells were tested. Results: An overlap between PGN intrinsic fluorescence and red/far-red fluorescent dyes occurred, rendering the evaluation of some parameters impossible for PGN. LPS induced sub-lethal cytotoxicity at the lowest dose (from 10 ng/ml). However, the most spectacular changes occurred with zymosan. In addition, zymosan, but not LPS, induced phagosome maturation and oxidative burst. Conclusions: Given the fact that β-glucans can be up to 100 fold more concentrated in organic dust than LPS, these results suggest that β-glucans could play a major role in macrophages impairment following heavy dust exposure and will deserve further investigation in the near future.

The possibilities to discriminate with hyperspectral imaging system, SWIR ImSpector N25E in grass mixtures of the pure species Festuca rubra L., Trifolium repens L., Agrostis capillaris L., Hieracium aurantiacum L., Arnica montana L.was the objective of this study. All the samples were collected from natural meadows, from the National Apuseni Park, Apuseni Mountains, from Gârda area. The samples were naturally dried then prepared using the protocol for NIRS analyze. The model built with PLS–DA, was used to demonstrate wether the classes discrimination between pure species is possible or not. The goal of this study was to see in other images if the pure species are or are not recognized according to the spectral data base. The potential of using the Hyperspectral Imaging NIR (Camera NIR) to discriminate or to identify pure species was confirmed. For this technique the MatLab program was used .A percentage of more than 96% correct prediction for species discrimination was obtained. This study should drive to a more important point, which is to verify whether the toxic species are or are not used as food for animals in the natural meadows. The floristic composition of a meadow can be determined only if we have in the data base, dates for each identified species, as being part of the mix. [less ▲]

Hydrogen is widely considered as the most promising energetic carrier. At an industrial scale, steam reforming of methane is currently the major hydrogen producing process. But it may also be produced from renewable biomass. Indeed, the fermentative production of hydrogen from renewable biomass using anaerobic bacteria could at least partially reduce our dependence on fossil fuel, decrease the carbon dioxide emissions and produce “green” energy. It offers the potential production of usable hydrogen from a variety of renewable resources such as carbohydrates wastes from agriculture or agro-food industries. This technology is based on anaerobic fermentation, called dark fermentation, by chemotrophic bacteria. The investigations carried out at CWBI involve selection and characterization of bacteria strains able to produce biohydrogen efficiently and with a wide range of substrate. The selected strains at the laboratory has been characterised as Clostridium sp. In order to produce hydrogen at high yields and production rates, the biotechnological process needs to be further optimized and efficient bioreactors must be designed. At CWBI, a new reactor called “horizontal rotating cylinder bioreactor” allows the production of biohydrogen from glucose with our Clostridium sp. strain with a high yield and production rate. This reactor, working continuously, has an internal volume of 2.3l but a working volume (liquid phase) of 300ml. Firstly, it enhances the hydrogen production rate by partially fixing the bacteria on the porous cylinder and thus increasing the cell concentration in the bioreactor. Secondly, the rotative cylinder enables efficient gas transfer (mainly hydrogen) from the liquid phase where it is produced by the bacteria. This is an important way to enhance hydrogen production yield by allowing the bacteria metabolism to shift in a fermentation type that produces more hydrogen. This was confirmed by increasing or decreasing the total pressure in the bioreactor and observing the influence of hydrogen production. The liquid to gas hydrogen transfer is possibly an important factor to enhance the biogas production. Our investigation confirmed this by testing different liquid to gas transfer condition in BHP test (batch fermentation in 250ml serum bottles).This was made either by decreasing total and partial pressure or by increasing the mixing state of the media. Our work concludes the importance of providing good liquid to gas transfers in the biohydrogen producing reactors to enhance the hydrogen production and reach higher yields and production rates.

Background: In horses-athletes, exercise has been shown to be an important regulator of immune cells and their functions, and catecholamines to be essential components of the physiological response to exercise. Objectives: The purpose of the present study was to compare immunological reactions and molecular events during exercise and epinephrine infusion. Methods: Horses were submitted to exercise or epinephrine infusion for 10 min. Blood samples were collected at T0, T5, Tl0, T20 and T40 min for biochemistry and haematology at T0 and T20 min for RNA extraction and microarray analysis. Results: In both protocols, packed-cell-volume and neutrophils peaked at T5 and T10, and returned to baseline at T40. Lymphocytes increased at T5 with exercise and at T20 with epinephrine and then remained high until the end of the protocols. Between T0 and T20, 55 probes, coding for 25 genes, and 19 probes, coding for 11 genes, were differentially regulated with epinephrine and exercise respectively (P<0.001). Ten of the genes over-expressed with epinephrine were related to inflammatory response and leukocytes trafficking and activation. Among the genes with the highest significant fold changes following exercise were FOS, DUSP-1 and CXCL1. FOS was over-expressed in both conditions. Among genes differentially regulated, Ingenuity software identified 3 overlapping functional networks with epinephrine and 1 functional network with exercise that overlapped the 3 epinephrine networks. Conclusions: Circulating leukocytes distribution and gene expression are rapidly affected following exercise and epinephrine infusion. Distinct but closely-related sets of gene activities were shown to be altered with exercise and epinephrine, with lesser changes in the immunological pattern with physical stress than epinephrine alone, arguing for compensatory mechanisms in exercise.

is wasted through the cooling liquid and the exhaust gases. Thus, it would be possible to convert this wasted heat in order to improve the engine overall efficiency and reduce the fuel consumption of the vehicle. This shows the big interest in energy recovery systems. This paper presents the various systems enabling the recovery of this energy. A Rankine cycle, widely used in the industry, is of particular interest. The efficiency of energy conversion varies from 5 to 20 % depending of its conception (working fluid, architecture, coupling…). Moreover, the layout of the Rankine cycle integrated within a vehicle depends on the choice of the working fluid as well as the technologies of the components i.e. the expander, the evaporator, the condenser and the pump. Within this context, the issue regarding the mass and the size of the system has to be considered. Finally, we present several solutions of Rankine systems for passenger car application and show each advantage and limits. [less ▲]

Recent understanding of HIV-1 pathogenesis mechanism has changed our views about possible mechanisms of CD4T-cell depletion during infection. Apart from HIV-1-mediated killing a more comprehensive explanation has appeared that includes T cell exhaustion and chronic immune activation as a central feature in HIV-1 pathogenesis. While highly active antiretroviral therapy (HAART) markedly reduces viral load, T cell activation levels and soluble markers of inflammation remain abnormally high. Markers of chronic activation, such as CD38, PD-1 or HLA-DR on T cells, appear to be better predictors for clinical progression during HIV infection than HIV RNA levels and CD4Tcell counts alone. Therefore, a better understanding of HIV-índuced immune activation and the design of new immunomodulatory approches in combination with HAART are needed. We have generated an efficient model of human stem cells (HSCs) engraftment in NOD/LtsZ-scidlL-2Rnull (NSG) mice that supports chronic HIV infection with high plasma viral loads. HIV-1 infection in these humanized mice is characterized by widespread immune activation with increased expression of PD-1, HLA-DR, CD38, CD69, CD25 and other immune activation markers. These humanized mice provide an effective in vivo system for the assessing novel approaches for their potential in suppressing chronic immune activation during HIV-1 infection, in absence of interference of antiretroviral therapy. In this study, we evaluated in vivo the benefits of two novel approaches aimed at reducing HIV-induced immune activation. Minocycline is an antibiotic of the tetracycline family with anti-inflammatory and immunomodulatory properties affecting CD4 T cells activation by a mechanism involving the inhibition of the NF-AT1 transcription factor activity. We hypothesized that this antibiotic could suppress the HIV-1-induced chronic immune activation and thus, limit the HIV pathogenesis when combined to HAART. Therefore, we treated HIV-1 (JRCSF) infected-humanized NSG mice with minocycline (100mg/kg/day) for 60 days. We next evaluated the expression, by flow cytometry, of several T cells activation markers together with CD4+T cells counts. Our data suggest that minocycline is effective in suppressing HIV-1 induced immune activation in peripheral blood and lymphoid organs (spleen, lymph nodes and bone marrow). Levels of cellular immune activation markers such as PD-1, HLA-DR, CD38, CD69, CD25, CD28 and CTLA-4 were significantly lower in minocycline treated group. These immunological benefits of minocycline were correlated with higher CD4+T cell counts in the treated group. The immune activation which is associated with retroviral infection is also associated with increased levels of intracytoplasmic cyclic AMP which could act as a positive feedback loop in the infection since several reports have suggested that cAMP and downstream signaling pathways play an important role in the permissivity of susceptible cells to HIV infection and replication. We have used a peptide which prevents the binding of the catalytic subunit of PKA type I to its anchoring protein and therefore blocks most effects of cyclic AMP within lymphocytes and monocytes (RIAD peptide). Mice were treated with 3.5 mg/kg of RIAD peptide weekly. Treatment of humanized mice with RIAD peptide limited viral replication after high dose of HIV intraperitoneal challenge and reduced the intracytoplasmic levels of cyclic AMP. Further experiments are needed to better appreciate the therapeutic potential of these novel therapies in the suppression of HIV-induced chronic immune activation. [less ▲]

We report the observation of a multi-chord stellar occultation by the dwarf planet (136199) Eris. The event was observed on November 6, 2010 UT, from two sites in Chile. Our observation is consistent with a spherical Eris with radius RE=1163±6 km, density =2.52±0.05 g cm-3, and visible geometric albedo pV=0.96+0.09 -0.04. Besides being remarkably similar in size to Pluto, Eris appears as one of the intrinsically brightest objects of the solar system, with a density suggesting a mainly rocky interior. Upper limits of about 1 nbar are derived for the surface pressure of possible nitrogen, argon or methane atmospheres of the dwarf planet. [less ▲]

We have taken advantage of a stellar occultation by the dwarf planet Makemake on 2011 April 23, to determine several of its main physical properties. We present results from a multisite campaign with 8 positive occultation detections from 5 different sites, including data from the 8-m VLT and 3.5-m NTT telescopes in Chile, which have very high temporal resolution. Because the star was significantly fainter than Makemake (setting a record in the magnitude of a star whose occultation has been detected), the occultation resulted in a drop of just ~0.3 mag in the lightcurves. From the lightcurves we have been able to determine the size and shape of the body, its geometric albedo and constraints on its atmosphere. [less ▲]

Between February 2010 and May 2011, our group has observed five stellar occultations by Trans-Neptunian Objects (TNOs), giving the size and shape for some of the biggest TNO's: Varuna, Eris, 2003 AZ84, Makemake and Quaoar. Here we present two of them: the January 08 stellar occultation by 2003 AZ84, and the May 04 by Quaoar. For the event of 2003 AZ84 we obtained one positive and another negative occultation chords in Chile. We give a lower limit to the diameter of the TNO. The event of Quaoar was observed from 16 sites distributed in Uruguay, Argentina, Chile and Brazil. Five of them yielded positive detection of the occultation. A preliminary analysis shows that the body is probably elongated and significantly bigger than the size determined by Fraser & Brown 2010, with a diameter of 890km. Using the size determined by the occultation, we will discuss the implications for the body density and albedo determination. The upper limit of the atmosphere is also studied. [less ▲]

Nous nous focalisons sur les organisations du secteur non marchand présentes dans cette région marquée par d’interminables conflits et guerres fratricides à caractère ethnique, une instabilité politique, une fragile démocratie ou une faillite quasi totale de l’Etat. <br />Notre problématique consiste à comprendre l’influence du contexte culturel et institutionnel dans le choix ou l’adoption de telle ou telle autre approche de Management des ressources humaines par les ONG internationales au Burundi. Dans ce pays, les grandes valeurs qui marquent la culture nationale sont notamment l’attachement à la famille, la confiance discrète et le dialogue comme mode de résolution de conflits entre des personnes ou groupes de personnes. Ainsi, tenterons-nous de répondre à la question centrale suivante: Des contextes culturels et institutionnels différents peuvent-ils affecter la cohérence des pratiques de GRH et l’intégration de celles-ci dans la stratégie globale de l’organisation? <br />Pour y répondre, nous adoptons une méthodologie qualitative à travers une étude de cas et une analyse exploratoire des données issues d’interviews semi-directives et d’observations directes réalisées sur terrain au Burundi. Les résultats de cette étude penchent davantage vers un style managérial négocié qui se situe entre l’imposition du style managérial du pays d’origine et la soumission au style de management local. <br />Notre étude se termine par la formulation d’un certain nombre d’hypothèses qui seront, par la suite, validées ou infirmées dans nos études ultérieures à la suite d’une analyse plus approfondies de données empiriques portant sur plusieurs ONG internationales.

Introduction: Le but de notre étude était de déterminer si une injection de plasma enrichi en plaquettes (PRP) pouvait améliorer et accélérer le processus de cicatrisation de tendons d'Achille de rats rompus. Matériel et méthode : Un défect de 5mm a été réalisé chirurgicalement au niveau de tendons d'Achille de 120 rats. Soixante rats ont reçu respectivement une infiltration de PRP ou PBS in situ après chirurgie. Vingt rats de chaque groupe ont été euthanasiés après 5, 15 et 30 jours. Quinze tendons de chaque groupe ont été directement soumis à un test de traction biomécanique jusqu'à rupture à l'aide de clamps de type "cryo-jaw" et ensuite collectés pour réaliser des analyses transcriptomiques. Des études histologique et biochimique ont également été réalisées sur les 5 tendons restant de chaque groupe. Résultats: Les tendons du groupe PRP étaient plus résistants à la rupture à 15 et 30 jours que ceux du groupe contrôle. La section transverse des tendons était significativement plus grande au sein du groupe PRP à J5 et J15. Les contraintes étaient significativement plus grandes au sein des tendons dans les phases tardives de cicatrisation. L'étude histologique montrait une augmentation de coloration pour les fibres de collagène à J5 au sein du groupe PRP, résultats confirmés par l'analyse biochimique montrant une augmentation de la concentration de collagène au sein du "cal" tendineux. L'expression de la ténomoduline, un marqueur de la différentiation des ténocytes, était significativement plus important au sein du groupe PRP à J5. Aucune différence significative en terme d'ARNm n'a été observée pou r le collagène de type III ni pour la MMP-9, à aucun temps, entre les 2 groupes. Conclusion : Une injection de PRP au sein de tendons d'Achille de rats rompus influence les phases précoces du la cicatrisation tendineuse, entrainant une meilleure résistance mécanique à la rupture.

Medicago sativa or Alfalfa is a flowering plant that belongs to Pea Family that is widely grown throughout the world as forage for cattle, and is most often harvested as hay. Medicago Sativa usually has the highest nutritive value of all common hay crops. This work aims to highlight a way for direct, non-destructive analysis of crude protein content in Medicago sativa hays. The primary objective was to build a model for crude protein calibration for Medicago sativa based on FT-NIR spectroscopy. The samples for analysis were collected over two experimental years (2008-2009) from field trials from the research station– Agricultural Development, Jucu. In order to construct the model, references values are needed; for this reason, crude protein content was determined using the classical Kjeldahl method (Kjeltec Auto Analyser, Tecator). The values for crude protein ranged from 12.63% to 19.12% on the dry matter basis. The regression models build was based on Partial Least Squares (PLS) calculated with the SIMPLS algorithm, using different pre-processing techniques and leave-one-out cross validation. Calibration of the two years together drove to a coefficient of determination for cross validation,R2, of 0.965. The robustness of the model was confirmed by applying it to independent samples (external validation) where the coefficient of determination was R2 = 0.977, RMSEP = 0.8. The results obtained indicated that NIRS can be used to determine crude protein, which could be used as a criteria for quality control of Medicago sativa hays. [less ▲]
