[more ▼]Purpose To evaluate the effects of a single intra-articular injection of a new biomaterial consisting in a mix of alginate-chitosan (AC) beads and a viscous thermogelling chitosan-based (H) hydrogel on cartilage lesion in osteoarthritis (OA) rabbit model. These effects were compared to those obtained with the intra-articular injection of either chitosan-based (H) hydrogel without the AC bead or saline solution. Methods OA was surgically induced by the transection of the anterior cruciate ligament (ACLT) in HYLA albino rabbits. One week after surgery, animals were randomly divided into 3 groups: group I (n=7): mix of AC beads and H hydrogel; group II (n=7): H hydrogel alone; group III (n=7): saline solution (control). The treatments (900 µl) were injected intra-articularly. X-rays from the right knee were performed before surgery, at the time of injection and at sacrifice. The standard radiographs were acquired in extension and scored by the Kellgren and Lawrence (K&L) scale. After 6 weeks, animals were euthanized and the right joint was dissected. The macroscopic evaluation of cartilage from femoral condyles and tibial plateaus stained with India ink was done. Histological sections stained with Safranine-O/fast green from bearing areas of each compartment were evaluated according to the OARSI histological score. Briefly, the evaluation considered: staining of the cartilage matrix (0-6), cartilage structure (0-11), chondrocyte density (0-4) and cluster formation (0-3), where 0 represented a normal situation and 24 points the maximum severity score. Blood samples were collected the day of injection and prior the sacrifice. Prostaglandin E2 (PGE2) and C-reactive protein (CRP) were measured in serum using immunoassays. Results The X-rays analysis showed a significant decrease (p <0.05) of the K&L score in group I (AC beads and H hydrogel; 1.5 ± 0.2) compared with group II (H hydrogel; 2.2 ± 0.5) and group III (saline solution; 3.0 ± 0.4). The size and the severity of the macroscopic OA cartilage lesion tended to decrease in group I compared to the other groups. The histological global score that refers to all compartments of the knee joint was significantly decreased in group I (11.0 ± 0.7) compared to group II (14.4 ± 0.6, p <0.01) and group III (14.8 ± 0.6, p <0.001). No significant variation of PGE2 and CRP serum levels were observed in each after 6 weeks follow-up whatever the treatment injected. Conclusions This study showed that a biphasic hydrogel composed by AC beads and H hydrogel prevented OA in rabbit with ACL transection. This effect was not observed with the hydrogel alone, suggesting that AC beads play a role in joint protection. The preventive effect was observed in all joint compartments indicating a global protective effect of this new viscosupplementation.

In a second step, we investigated the genetic modulatory effects of chondroitin sulfate (CS) in this model. Methods: Synovial cells (SC) were isolated from OA synovial specimens obtained from 12 patients undergoing knee replacement. The inflammatory status of the synovial membrane was characterized according to macroscopic criteria. At the surgery time, the synovial membrane was dissected and biopsies from N/R and I areas cultured separately for a period of 7 days in the absence or in the presence of highly purified bovine CS (200 µg/ml, Bioibérica S.A., Barcelona, Spain). Total RNA was extracted using the RNeasy Mini Kit. RNA purity and quality were evaluated using the Experion RNA StdSens Analysis kit (Bio-rad Laboratories). Gene expression profiling was performed using Illumina’s multi-sample format Human HT-12 BeadChip (Illumina Inc.). Differential analysis was performed with the BRB array tools software. Class Comparison test between N/R and I conditions, N/R and N/R-CS conditions and I and I-CS conditions was based on paired t-test where N/R and I, N/R and N/R-CS and I and I-CS were paired for each patient. The biological relevance of up- and down-regulated genes was analyses with Ingenuity Pathways Analysis (Ingenuity® Systems). Results: From among 47000 probes, 18253 were filtered out. Probes with a p-value below than 0.005 were chosen and classified as up- or down-regulated ones. By this way, 465 differentially expressed genes between N/R and I areas were identified. Many inflammatory mediators appear differentially expressed. The interferon alpha-inductible protein 6 (IFI6) was the most up-regulated. We also identified the hydroxysteroid (11-beta) dehydrogenase 1 (HSD11B1), the cathepsin K (CTSK), the chemokine (C-X-C motif) ligand 1 (CXCL1) and the EBV-induced G-protein coupled receptor 2 (EBI2). The differential expression of intermediates involved in angiogenesis pathway was also revealed between N/R and I areas. Among them, R-spondin-3 (RSPO3), the secreted phopshoprotein 1 (SPP1) and aquaporin 9 (AQP9) were up-regulated whereas ADAMTS1 was down-regulated. Finally, in the Wnt signaling, RSPO3 was up-regulated unlike dickkopf homolog 3 (DKK3) which was in turn down-regulated. We next performed a class comparison test between N/R and N/R-CS in one hand and between I and I-CS the other hand. 489 genes were identified as differentially expressed genes between N/R and N/R-CS conditions while 219 genes were identified between I and I-CS conditions. In this latter, our attention was focused on the down-regulated genes. Among them, we identified a number implicated in angiogenesis and cell migration pathways. Thus, the endothelial cell-specific molecule-1 (ESM1), the Transmembrane-4-L-six-family-1 (TM4SF1), the 5’-Ectonucleotidase (NT5E) and the growth arrest-specific gene 6 (GAS6) were down-regulated by CS. Conclusions: Our work demonstrates the differential gene expression profile between paired non inflammatory and normal/reactive areas of synovial membrane as well as the modulatory effects of CS on gene expression in the inflammatory areas, especially regarding genes involved in both angiogenesis and cell migration.

[more ▼]Purpose: Synovial inflammation plays a key role in the pathophysiology process of osteoarthritis (OA). We have previously compared the gene expression pattern of synovial cells isolated from inflammatory (I) or normal/reactive (N/R) areas of a synovial membrane harvested from the same OA patient. We identified a large number of mediators belonging to key pathways involved in OA pathogenesis. The aim of this study was to validate different potential new targets for the diagnosis and/or the treatment OA. Methods: Synovial cells (SC) were isolated from synovial specimens obtained from OA patients undergoing knee replacement. The inflammatory status of the synovial membrane was characterized according to macroscopic criteria. The biopsies from N/R and I areas were cultured separately for a period of 7 days. Microarray gene expression profiling between N/R and I areas was performed. The biological relevance of up- and down-regulated genes was analyzed with Ingenuity Pathways Analysis. Western blot and immunohistochemistry confirmed the identified genes most differentially expressed in the key pathways. The production of the triggering receptor expressed on myeloid cells-1 (TREM1), the alarmin S100 calcium binding protein A9 (S100A9), the wingless-type MMTV integration site family, member 5A (Wnt-5A) and the stanniocalcin 1 (STC1) were evaluated by Western blot. S100A9, hyaluronan synthase-1 (HAS1) and STC1 expression and localization were investigated by immunohistochemistry. Results: 896 genes differentially expressed in N/R and I areas were identified. The key pathways were related to inflammation, cartilage metabolism, Wnt signaling and angiogenesis. In the inflammatory gene pattern, TREM1 and S100A9 were strongly upregulated. We validated the production of these proteins in OA synovial biopsies by Western blot. TREM1 and S100A9 were increased in I compared to N/R synovial cells culture. S100A9 was observed in the perivascular area and in sublining cells in I synovial biopsies, but not in N/R biopsies. An increased staining was also observed in the intima lining layer of I when compared to N/R biopsies. The most upregulated anabolism enzyme in I synovial biopsies was HAS1. Using immunohistochemistry, we observed in I areas an increase of the HAS1-positive cells mainly in the intima lining. We also studied the protein production of Wnt-5A, the most upregulated intermediate of Wnt signaling pathway. The protein level was increased in I compared to N/R areas. Finally, in the angiogenesis pathway, one the most u-regulated gene was STC1. A significant increase of STC1 production was observed in I areas compared to N/R areas by Western blot. This result was also supported by the immunohistochemical analysis. In I area, the staining for STC1 was more intense in perivascular and sublining cells. Conclusions: Synovial membrane inflammation is a key target for OA treatments. In this work, we have identified proteins involved in the synovitis pathways like angiogenesis, cells infiltration and matrix remodeling. These proteins could be targeted by drugs and used as companion biomarkers for evaluating their efficacy. Although qualitative, our results could also yield to the identification of markers of the disease. This investigation has to be further pursued.

[more ▼]Purpose: Chondroitin sulfate (CS) is one the most used molecules in the management of OA. In this study, we performed a microarray analysis and identified a differential expression profile between control and IL-1β stimulated synovial fibroblast cells cultures. In a second step, we investigated the effects of CS on this gene expression profile. Methods: OA synovial specimens were obtained from 12 patients undergoing knee replacement. At the surgery time, the synovial membrane was dissected. Synovial fibroblast cells (SFC) were enzymatically isolated and used after four passages (P4). SFC were pre-treated 1 hour with highly purified bovine CS (200 µg/ml, Bioibérica S.A., Barcelona, Spain) before treatment with IL-1β (1 ng/ml) for 24 hours. Total RNA was extracted using the RNeasy Mini Kit. RNA purity and quality were evaluated using the Experion RNA StdSens Analysis kit (Bio-rad Laboratories). Gene expression profiling was performed using Illumina’s multi-sample format Human HT-12 BeadChip (Illumina Inc.). Differential analysis was performed with the BRB array tools software. Class comparison test between control (Ctl) and interleukin (IL)-1β conditions, Ctl and Ctl/CS and IL-1β and IL-1β/CS conditions was based on paired t-test where Ctl and IL-1β, Ctl and Ctl/CS and IL-1β and IL-1β/CS were paired for each patient. The biological relevance of up- and down-regulated genes was analyses with Ingenuity Pathways Analysis (Ingenuity® Systems). Probes with a p-value below 0.001 were chosen and classified as up- or down-regulated ones. Results: 3308 genes were identified as differentially expressed genes between Ctl and IL-1β conditions. We observed a differential profile of expression of major pathways involved in OA pathogenesis. The key identified pathways were related to inflammation, complement cascade, angiogenesis, cartilage catabolism and anabolism and Wnt signaling. In the inflammatory network, the most upregulated cytokines were IL-8 and IL-6 with a fold change of 156.25 and 58.8 respectively. We also identified several chemokines, enzymes and metallothioneins (MTs). Complement factor B (CFB) and complement component 3 (C3) are two factors upregulated in the inflammatory complement cascade. We also identified some genes implicated in the angiogenesis pathway. The most upregulated was Stanniocalcin 1 (STC1) with a fold change of 9.09. The differential expression of intermediates involved in both cartilage anabolism and catabolism was revealed by the IL-1β stimulation, showing an imbalance in favour of catabolism. MMP-3 was largely upregulated (fold change of 62.5). Wnt 5A and low density lipoprotein receptor-related protein (LRP8) were significantly upregulated while frizzled homolog 2 (FZD2) and dickkopf homolog 3 (DKK3) were downregulated in the Wnt signaling pathway. We next performed a class comparison test between Ctl and Ctl/CS in one hand and IL-1β and IL-1β/CS on the other hand. 660 genes were identified as differentially expressed between Ctl and Ctl/CS conditions while 241 genes were identified between IL-1β and IL-1β/CS. Among them, our attention was focused on two genes upregulated in the presence of CS: lysyl oxidase-like 4 (LOXL4) and claudin 11 (CDLN11), two genes that negatively regulate cell invasion. Conclusions: We here evidenced in synovial fibroblast cells the modulation of gene expression following IL-1β stimulation. We also demonstrated the modulatory effects of CS on gene expression and isolated several CS-modulated genes of interest such as LOXL4 and CDLN11, which could constitute new mechanisms of action of the molecule and contribute to explain the symptomatic efficacy of CS in the treatment of OA.

[more ▼]The space missions CoRoT and Kepler provide high quality data that allow to test the transport of angular momentum in stars by the seismic determination of the internal rotation profile. Our aim is to test the validity of the seismic diagnostics for red giant rotation that are based on a perturbative method and to investigate the oscillation spectra when the validity does not hold. We use a non-perturbative approach implemented in the ACOR code [1] that accounts for the effect of rotation on pulsations, and solves the pulsations eigenproblem directly for dipolar oscillation modes. We find that the limit of the perturbation to first order can be expressed in terms of the core rotation and the period separation between consecutive dipolar modes. Above this limit, each family of modes with different azimuthal symmetry m, has to be considered separately. For rapidly rotating red giants, new seismic diagnostics can be found for rotation by exploiting the differences between the period spacings associated with each m-family of modes.

[more ▼]Thanks to the CoRoT and Kepler spacecrafts, scaling relations (linking seismic indices and global stellar parameters) are becoming the cornerstone of ensemble asteroseismology. Among them, the relation between the cut-off frequency and the frequency of the maximum in the power spectrum of solar-like pulsators as well as the relation between mode lifetime and the effective temperature remain poorly understood. However, a solid theoretical background is essential to assess the accuracy of those relations and subsequently of the derived stellar parameters. We will thus present recent advances on the understanding of the underlying mechanisms governing those relations and show that the physics of mode lifetime (thus of mode damping) plays a major role.

[more ▼]CoRoT and Kepler measurements reveal us that the amplitudes of solar-like oscillations detected in red giant stars scale from stars to stars in a characteristic way. This observed scaling relation is not yet fully understood but constitutes potentially a powerful diagnostic about mode physics. Quasi-adiabatic theoretical scaling relations in terms of mode amplitudes result in systematic and large differences with the measurements performed for red giant stars. The use of a non-adiabatic intensity-velocity relation derived from a non-adiabatic pulsation code significantly reduces the discrepancy with the CoRoT measurements. The origin of the remaining difference is still unknown. Departure from adiabatic eigenfunction is a very likely explanation that is investigated in the present work using a 3D hydrodynamical model of the surface layers of a representative red giant star.

Tempête la plus dévastatrice depuis 1999, la forêt des Landes et ses pins maritimes paient un lourd tribut à ce phénomène extrême: 60% de la superficie est touchée, environ 40 millions de m3 de bois sont à terre, quatre fois la récolte annuelle. Il faudra attendre plusieurs mois avant que les aires de stockage par aspersion soient opérationnelles. Trop tard, le pin maritime montre déjà des signes de bleuissement de son bois, il est invendable sur les marchés à forte valeur ajoutée, là où l’esthétisme prime. Écarté des meilleurs débouchés, le lambris et le plancher, le manque à gagner est énorme. Un tel scénario catastrophe, notre région s’y prépare depuis 2005, tirant les enseignements des expériences étrangères et fondant son action sur les spécificités de notre forêt, de notre filière. C’est dans ce cadre que le 28 février dernier, à Eupen, des grumes d’épicéa stockées depuis presque cinq ans ont été extraites des bâches hermétiques qui les protégeaient. Comment le bois est-il ressorti de cette épreuve? Que penser de cette méthode alternative de stockage? Quelle place lui réserver ? Benoit Jourez du Laboratoire de Technologie du Bois du DEMNA (Département de l’Étude du milieu naturel et agricole) nous a apporté son éclairage et nous a conviés à l’ouverture de la poche étanche.

[more ▼]We present a brief summary of what is currently known about white dwarf stars, with an emphasis on their evolutionary and internal properties. As is well known, white dwarfs represent the end products of stellar evolution for the vast majority of stars and, as such, bear the signatures of past events (such as mass loss, mixing phases, loss and redistribution of angular momentum, and thermonuclear burning) that are of essential importance in the evolution of stars in general. In addition, white dwarf stars represent ideal testbeds for our understanding of matter under extreme conditions, and work on their constitutive physics (neutrino production rates, conductive and radiative opacities, interior liquid/solid equations of state, partially ionized and partially degenerate envelope equations of state, diffusion coefficients, line broadening mechanisms) is still being actively pursued. Given a set of constitutive physics, cooling white dwarfs can be used advantageously as cosmochronometers. Moreover, the field has been blessed by the existence of four distinct families of pulsating white dwarfs, each mapping a different evolutionary phase, and this allows the application of the asteroseismological method to probe and test their internal structure and evolutionary state. We set the stage for the reviews that follow on cooling white dwarfs as cosmochronometers and physics laboratories, as well as on the properties of pulsating white dwarfs and the asteroseismological results that can be inferred.

[more ▼]Nonradial pulsations in Extreme Horizontal Branch stars (also known as hot B subdwarfs or sdB stars) offer strong opportunities to study through asteroseismology the structure and internal dynamics of stars in this intermediate stage of stellar evolution. Most sdB stars directly descend from former red giants and are expected to evolve straight into white dwarfs after core helium exhaustion. They thus represent the most direct link between these two stages. Their properties should therefore reflect both the outcome of the core evolution of red giant stars and the initial state for a fraction of the white dwarfs. We review the status of this field after a decade of efforts to exploit both p-mode and g-mode pulsating sdB stars as asteroseismic laboratories. From the discoveries of these two classes of pulsators in 1997 and 2003, respectively, up to the current epoch of data gathering of unprecedented quality from space, a lot of progress has been made in this area and prospects for future achievements look very promising.

[more ▼]Subdwarf B (sdB) stars are hot, compact, and evolved objects that form the very hot end of the horizontal branch, the so-called Extreme Horizontal Branch (EHB). Understanding the formation of sdB stars is one of the remaining challenges of stellar evo- lution theory. Several scenarios have been proposed to account for the existence of such objects, made of He-burning core surrounded by very thin H-rich envelope. They give quite different theoretical mass distributions for the resulting sdB stars. Detailed astero- seismic analyses, including mass estimates, of 15 pulsating hot B subdwarfs have been published since a decade. The masses have also been reliably determined by light curve modeling and spectroscopy for 7 sdB components of eclipsing and/or reflection effect binaries. These empirical mass distributions, although based on small-number statistics, can be compared with the expectations of stellar evolution theory. In particular, the two He white dwarfs merger scenario does not seem to be the dominant channel to form iso- lated sdB stars, while the post-red giant branch scenario is reinforced. This opens new questions on extreme mass loss of red giants to form EHB stars, possibly in connection with the recently discovered close substellar companions and planets orbiting sdB stars.

[more ▼]In response to wounding or herbivore attack, leaves and roots of higher plants release volatile organic compounds (VOCs). To date, VOCs analysis and plant−plant interaction studies have been mainly performed on aboveground plant tissues, leaving the roles played by root VOCs in plant−plant interaction unexplored. In this context, this project aims at setting up an original experimental device allowing both dynamic trapping of VOCs emitted by mechanically damaged H. distichon roots and the study of the roles played by root VOCs in intra and interspecific plant−plant interactions. The experimental device consists of Barley seedlings cultivated in closed PTFE reactors filled with wet sand. Before being analysed by gas chromatography−mass spectrometry, root VOCs are trapped via a dynamic system on Tenax cartridges using a charcoal-filtered and humidified air. Preliminary results show that 7 day-old wounded Barley roots emit C9 fatty acid derivatives (E-non-2-enal and nona-2,6-dienal) as major compounds, contrasting with aboveground plant tissues that mainly emit C6 alcohols, aldehydes, and their derivative esters. For plant−plant interaction studies, receiver plants are exposed to an airflow enriched with VOCs from root damaged Barley plants of the same age.

In the context of minimal seesaw models we analyze the implications of a slightly broken U(1)R symmetry on charged lepton flavor violating decays. We find, depending on the R-charge assignments, models where charged lepton flavor violating rates can be within measurable ranges. In particular, we show that in the resulting models due to the structure of the light neutrino mass matrix muon flavor violating decays are entirely determined by neutrino data (up to a normalization factor) and can be sizable in a wide right-handed neutrino mass range.

[more ▼]VOC (volatile organic compounds) include a wide set of molecules which are mostly emitted by the plants. Atmospheric scientists are strongly interested in these compounds because of their important role in the atmospheric chemistry and their final impact on air pollution and climate change. Evaluation of current and future VOC emissions is thus necessary and requires a comprehensive understanding of VOC production and exchange dynamics under a wide panel of climatic conditions and ecosystems. Forest and non pastured grasslands have been largely studied for the last decade. However, knowledge about VOC fluxes from croplands remains scarce. Our study focuses on the VOC exchanges between a maize field and the atmosphere. It is incorporated in a wider project that aims to study VOC fluxes from two croplands (maize and winter wheat) and a pastured grassland. VOC fluxes have been measured on a maize field during the whole growing season using a micrometeorological method (eddy covariance). While first results show half-hourly bidirectionnal exchanges among all the preselected compounds, in average methanol stands for the greatest emitted VOC, followed by green leaf volatiles, and acetic acid is the greatest taken up VOC. Small isoprene and monoterpenes fluxes are also observed. A diurnal pattern is found for all those VOC, with greater emission/uptake during the day, suggesting a flux dependence on environmental parameters. These environmental controls will be further investigated [less ▲]Detailed reference viewed: 131 (17 ULg) Collaborations distantes synchrones dans les pratiques de conceptionBen Rajeb, Samia ; Leclercq, Pierre in International Journal of Design Sciences and Technology (2013, January)Cet article propose une analyse des pratiques de la collaboration architecturale dans des situations de travail distantes.

[more ▼]Based on the impairment of erythropoietin production after allogeneic hematopoietic cell transplantation (HCT), we previously reported in a phase-2 trial that recombinant human erythropoietin (rhEPO) therapy was very efficient when started one month after transplantation. We also demonstrated that anemia after nonmyeloabalative (NM) HCT was less sensitive to rhEPO therapy than after conventional allogeneic HCT. This prompted us to confirm these findings in a prospective randomised trial. One hundred and thirty-one patients were randomised (1:1) between no treatment (arm 1) or erythropoietin (Neorecormon) at the dose of 500 U/kg/week (arm 2). Once the target Hb (13g/dL) has been attained, the dose of rhEPO was reduced by half, while it was withheld when Hb was = 14g/dL. Cohort A included 42 patients on day 28 after myeloablative HCT, cohort B 39 patients on day 28 after NMHCT, and cohort C 50 patients on day 0 of NMHCT. Primary endpoints included proportion of complete correctors (i.e. patients reaching Hb = 13g/dL) and median time to achieve Hb correction in each arm. The proportion of complete correctors before day 126 posttransplant was 0% in group 1A vs 52.4% in group 2A, 0% in group 1B vs 69.5% in group 2B and 19.1% in group 1C vs 70.2% in group 2C. Median time to achieve Hb = 13g/dL was not reached in group 1B vs 49 days in group 2B; 363 and 59 days in groups 1A and 1B respectively and 363 and 87 days in groups 3A and 3B respectively (figure 1). Hb evolution in each group is shown in figure 2. Seventyone patients (47/62 in control groups and 24/57 in treated groups, p=0.0003) required red blood cell transfusions. The difference was most pronounced in cohort B. There was no difference in rates of thrombo-embolic events or other complications between the two arms. In conclusion, this is the first trial to demonstrate that EPO therapy hastens erythroid recovery and decreases transfusion requirements when started one month after allogeneic HCT.

[more ▼]In this paper we introduce and study a new property of infinite words which is invariant under the action of a morphism: We say an infinite word x, defined over a finite alphabet A, is self-shuffling if x admits factorizations: x=\prod_{i=1}^\infty U_iV_i=\prod_{i=1}^\infty U_i=\prod_{i=1}^\infty V_i with U_i,V_i \in \A^+. In other words, there exists a shuffle of x with itself which reproduces x. The morphic image of any self-shuffling word is again self-shuffling. We prove that many important and well studied words are self-shuffling: This includes the Thue-Morse word and all Sturmian words (except those of the form aC where a is a letter and C is a characteristic Sturmian word). We further establish a number of necessary conditions for a word to be self-shuffling, and show that certain other important words (including the paper-folding word and infinite Lyndon words) are not self-shuffling. In addition to its morphic invariance, which can be used to show that one word is not the morphic image of another, this new notion has other unexpected applications: For instance, as a consequence of our characterization of self-shuffling Sturmian words, we recover a number theoretic result, originally due to Yasutomi, which characterizes pure morphic Sturmian words in the orbit of the characteristic.

[more ▼]Due to the depletion of fossil fuels and the increase of greenhouse gas emissions, solutions are needed to replace petrol based products. As a consequence, the number of biobased products developed using agricultural feedstock is continuously increasing. This study focuses on the carbon footprint of bio-HDPE produced either from Brazilian sugar cane or Belgian sugar beet. The goal of this study is to compare the carbon footprint of bio-HDPE with the fossil one, taking into account the effect of land use change. Common boundaries of the agricultural systems comprise the cultivation step for both crops, i.e. sugar cane and sugar beet, with all associated energy and fertilizer consumptions, the transportation step from field to the industrial plant, the sugar crops transformation into hydrate bioethanol, the by-products valorisation, the dehydration and polymerization steps and the HDPE incineration as end of life issue. Fossil scenario includes the production of ethylene, its polymerization and its incineration. When comparing the entire life cycle of bio and fossil HDPE, the GHG emissions are lower for the biobased product which is the willing effect. This result is only valid if no Land Use Change (LUC) or Indirect Land Use Change (ILUC) effect appears. To assess the environmental impact of the deforestation or of the transformation of a pasture into a field, the EC-Guidelines from the European Union were used in order to calculate the CO2 emissions depending on several parameters. For sugar cane, LUC consists in the transformation of pastures into fields in the region of Sao Paulo in Brazil. Three scenarios can be developed based on different agricultural practices for pasture and field (tillage and fertilizers inputs): the best, the worst and the average. The best case leads to a supplementary environmental gain. The worst and average achieve additional emissions. A payback time, considering the time needed to find again an environmental gain compared to the fossil counterpart, was calculated for the average scenario which is equal to 12 years. The ILUC effect for sugar cane is assumed to be deforestation due to the transformation of forest into pasture induced by the previous LUC effect. The rate of deforestation can vary between 16% or 100% depending on used statistics and leads to a payback time of respectively 26 and 101 years. For sugar beet, no LUC is considered. Indeed, no land expansion is available in Belgium due to small available areas. In the case of an increase of bioplastics production, Belgium should import sugar beet from neighboring countries which can induce ILUC. In this study, sugar beet is assumed to be provided by the Netherlands on pastures previously transformed into fields. The average scenario implies a payback time of 8 years. This study permits to highlight the importance of LUC and ILUC especially for energetic crops dedicated to replace fossil products. This effect can reverse expected results and induce long payback times.

[more ▼]Though forested watersheds are really particular in terms of hydrodynamics, most of the hydrological models oversimplify the phenomena involved. More investigations are unavoidable to improve the knowledge and the modelling of this environment. Here is the aim of this study. The studied slope is located on the Houille watershed in the West of the Belgian Ardenne (50 1’47”N, 4 53’22”E) on a silty rocky soil. The site is situated under a Douglas ﬁr (Pseudotsuga menziesii (MIRB.) FRANCO) and spruce stand cover (Picea abies (L.) Karst). It is about 160 meters long with a North-West facing slope between 7 and 55%. The goal of the study is : - to characterise the hydrological and pedogeological dynamics along a forested slope, - to compare these dynamics with the tree growth. For the geopedological part of the study, eight pits were dug to describe the soil and take some soil samples used for granulometric, chemical, etc. analysis. We have used geophysical methods (Electrical Resistivity Tomography and Ground Penetrating Radar) to estimate the soil depth. As for the hydrological part of this study, moisture sensors (capacitive and TDR) have been installed in the pits along the slope. A dye tracing test has been performed to underline the preferential ﬂow and the importance of the subsurface ﬂow. Several trees have been equipped with dendrometers and some measures of the LAI and the height of the trees are planned.

[more ▼]Hydrofluorocarbons (HCFCs) are the first substitutes to the long-lived ozone depleting halocarbons, in particular the chlorofluorocarbons (CFCs). Given the complete ban of the CFCs by the Montreal Protocol, its Amendments and Adjustments, HCFCs are on the rise, with current rates of increase substantially larger than at the beginning of the 21st century. HCFC-142b (CH3CClF2) is presently the second most abundant HCFC, after HCFC-22 (CHClF2). It is used in a wide range of applications, including as a blowing foam agent, in refrigeration and air-conditioning. Its concentration will soon reach 25 ppt in the northern hemisphere, with mixing ratios increasing at about 1.1 ppt/yr [Montzka et al., 2011]. The HCFC-142b lifetime is estimated at 18 years. With a global warming potential of 2310 on a 100-yr horizon, this species is also a potent greenhouse gas [Forster et al., 2007]. First space-based retrievals of HCFC-142b have been reported by Dufour et al. [2005]. 17 occultations recorded in 2004 by the Canadian ACE-FTS instrument (Atmospheric Chemistry Experiment – Fourier Transform Spectrometer, onboard SCISAT-1) were analyzed, using two microwindows (1132.5–1135.5 and 1191.5–1195.5 cm-1). In 2009, Rinsland et al. determined the HCFC-142b trend near the tropopause, from the analysis of ACE-FTS observations recorded over the 2004–2008 time period. The spectral region used in this study extended from 903 to 905.5 cm-1. In this contribution, we will present the first HCFC-142b measurements from ground-based high-resolution Fourier Transform Infrared (FTIR) solar spectra. We use observations recorded at the high altitude station of the Jungfraujoch (46.5°N, 8°E, 3580 m asl), with a Bruker 120HR instrument, in the framework of the Network for the Detection of Atmospheric Composition Change (NDACC, visit http://www.ndacc.org). The retrieval of HCFC-142b is very challenging, with simulations indicating only weak absorptions, lower than 1% for low sun spectra and current concentrations. Among the four microwindows tested, the region extending from 900 to 906 cm-1 proved to be the most appropriate, with limited interferences, in particular from water vapor. A total column time series spanning the 2004-2012 time period will be presented, analyzed and critically discussed. After conversion of our total columns to concentrations, we will compare our results with in situ measurements performed in the northern hemisphere by the AGAGE network.

[more ▼]A sharp increase in extreme heat and drought stress is projected in Belgium by the end of the 21st century, with the potential to signiﬁcantly reduce crops’ yields under current agricultural practices. This contribution uses an agro-hydrological model in order to assess the potential effects of climate evolution on crop development, yield, and water balance for the main agricultural productions in the Meuse catchment. Erosion risk is also evaluated. We show that grasslands and maize yield decrease and yield variability increases under climate change scenarios. The leaf area index study permits to put in emphasis the earlier start of the vegetation due to warmer climate. It appears that all the sensitive stages occur earlier in the season and that crops are negatively affected by summer drought stress. The better understanding of crops development under evolving climate allows us to propose some changes in agricultural practices and to assess their effectiveness. We evaluate different strategies of adaptation in agricultural practices in order to reduce the potential negative effects of climate change on grasslands and maize production. Adaptation strategies proposed are advanced sowing and harvesting date, introduction of a cover crop for maize and advance in the cutting dates for grasslands. In the particular case of the Vesdre catchment, shifting the growth period of maize permits to avoid the water-deﬁcit period and allow increased yield. This shift makes it possible to introduce a cover crop that will drastically reduce winter soil erosion. For grassland, the adjustment of the cutting dates favored the ﬁrst cut and the earlier start of the vegetation. The second cut is less proﬁtable due to summer drought stress. The vulnerability assessments focused on the main rotation encountered in the cultivated areas and in the difference in the cover type of these crops.

[more ▼]The influence of spatial scale on ecological processes and pattern formation, such as species distribution is a major research topic since decades. It has become even more relevant in the context of global change. In many studies the influence of a predictor on a response derived over multiple and discrete spatial scales is evaluated. Due to inherent issue of multiple testing, this approach can be problematic. In this study on bonobos distribution, we suggest a 3-steps procedure that overcomes this problem. It takes into account the decay of a predictor by using a weighting function of distance to the observation of interest. We use variables to account for human pressure, food availability, patchy structure of the forest and nesting sites re-use. In a first step, we run a model with a fixed scale for every predictor based on expert opinion. For significant variables, we derive then in a second step the distance weighted influence over a range of scales. This helps to narrow down the search for the final model parameter estimates. Findings indicate that bonobo distribution is driven on the intermediate scale by forest patches structure. Food availability explains their abundance only at smaller scales. Those results demonstrate the sadly well-known influence of habitat fragmentation on animals’ density and distribution but also highlight the importance to understand influences of scale, the animal perceptions of their environment, by using appropriate statistical procedures. Our method can be particularly useful to formulate specific management hypotheses for conservation. Furthermore, its principles can be of use to other types of studies, such as behavior.

[more ▼]Backgound: Measurement of total Myeloperoxidase (MPO) by ELISA is considered as a marker of neutrophil activation but is not the true indicator of the degree of its activity. In a dynamic pathology such as atherosclerosis, it may be important to measure the real active part of MPO because it represents the true witness of the oxidant potential of the enzyme. Aim: To identify the relation between coronary artery disease identified by coronaro-angiography on measured serum total and active MPO levels and evaluate the correlation between these MPO levels and the presence of clinically defined unstable condition. Methods: Prospective analyse of serum samples of patients before (within 30 min) coronaro-angiography. Total and active MPO concentrations were assessed by sandwich Elisa and SIEFED® method’s respectively. Results: Two hundred and twenty patients were included in this study (age: 66.1±10.7 years, 67% of male). Among these, 62% presented significant coronary artery disease (stenosis more than 60% at least in one épicardial coronary artery). Twenty four patients (11%) presented unstable coronary syndrome. Mean active and total MPO in the general population were 50.1±63.5 and 147.6±223.3 ng.mL-1 respectively. In comparison, mean active MPO was 47.1±47.9 ng.mL-1 in stable patients and 75.1±135.2 ng.mL-1 in unstable patients (p=0.04). Mean total MPO was 146.3±224.7 ng.mL-1 in stable patients and 158.2±215.8 ng.mL-1 in the unstable’s one (p=0.8). There was a significant correlation between active MPO levels and instability (r=0.14, p=0.04) not present for total MPO levels (r=0.016, p=0.8). Conclusion: We observed a correlation between active MPO and clinical instability while there was no correlation with total MPO. Our preliminary results suggest that this marker could be a powerful indicator of instability which could possess an important prognostic impact. This hypothesis requires an evaluation in wider population and during a prolonged follow-up.

[more ▼]In order to determine the mechanical behavior of a bulk TA6V alloy, a set of mechanical tests such as shear, compression, tensile monotonic tests, and tensile tests on notched samples are performed. The material is tested at constant strain rate. Full-field optical technique for displacement measurements and strain computation are used for all the experiments. Plastic anisotropy and tension–compression asymmetry are observed. The CPB06 [1] yield criterion adapted for hexagonal close packed (hcp) material is identified. The sensitivity of the material parameters on the identification method as well as the efficiency of the model to predict forces and displacement field are discussed. Validation is done by using Finite Element method (FEM) simulations and 3D Digital Image Correlation (3D-DIC) measurements on specimens with multi-axial stress and strain fields subjected to large deformation.

[more ▼]In the literature, many bijections between (labeled) Motzkin paths and various other combinatorial objects are studied. We consider abelian (un)bordered words and show the connection with irreducible symmetric Motzkin paths and paths in Z not returning to the origin. This study can be extended to abelian unbordered words over an arbitrary alphabet and we derive expressions to compute the number of these words. In particular, over a 3-letter alphabet, the connection with paths in the triangular lattice is made. Finally, we study the lengths of the abelian unbordered factors occurring in the Thue--Morse word.

[more ▼]Local interpretation of micro finite element (mu FE) simulations has become important in different fields of bone biomechanics. Although on an apparent level mu FE has successfully been validated against experiments, local validations are sparse and limited by imaging resolution. At the tissue level heterogeneity of Young's modulus has been reported. Although non-uniform material distribution have been shown to only have a minor influence on the apparent material properties, its impact on local material behaviour is largely unknown. By combining image-guided failure assessment (IGFA) using synchrotron-based-micro-computed tomography, strain mapping and inverse mu FE modelling, we present an experimental and computational framework which will allow studying local effects of intratrabecular heterogeneity of the Young's modulus.

[more ▼]Despite their importance for many astrophysical processes, massive stars are still not fully understood. Massive binaries offer an attractive way to improve our knowledge of the fundamental properties of these objects. However, some secondary effects are known to generate variations in the spectra of massive binaries, rendering their analyses more difficult. We present here a new approach to the computation of synthetic spectra of massive binaries at different phases of their orbital cycle. Our model starts with the Roche potential modified by radiation pressure and accounts for the influence of the companion star on the shape and physical properties of the stellar surface. We further account for gravity darkening and reflection effects to compute the surface temperature. Once the local gravity and temperature are determined, we interpolate in a grid of NLTE plan-parallel atmosphere model spectra to obtain the local contribution to the spectrum at each surface points. Then we sum all the contributions, accounting for the Doppler shift, and limb-darkening to obtain the total spectrum. The computation is repeated for different orbital phases and can be compared to the observations to determine the best parameters. We illustrate our method through the example of the LZ Cep system (O9III + ON9.7V).

[more ▼]The gut of lower termites is populated by numerous microbial species belonging to prokaryotes, fungi, yeasts and protists. These micro-organisms are organized in a complex symbiotic system, interacting together and with the insect host. Their likely ability to degrade ligno-cellulosic compounds could lead to improvements in second generation biofuels production. Lignin elimination represents a critical point as this polymer significantly interferes with industrial process of cellulose. Although host produces its own lignin-degrading enzymes, some symbionts may participate in digestion of lignin and its degradation products in termite gut. Here, we compared gut proteomes from R. santonensis after rearing on artificial diets composed of cellulose with and without lignin. The effect of lignin in artificial diets on different parts of the digestive tract was compared through liquid chromatography associated with tandem mass spectrometry (LC-MS/MS) experiments. Enzymatic assays were performed to characterize activities present in R. santonensis digestive tract after feeding on artificial diets. Microscopic observations of microbial communities provided some information on population balances after feeding experiment.

[more ▼]Dissipativity is an essential concept of systems theory. The paper provides an extension of dissipativity, named differential dissipativity, by lifting storage functions and supply rates to the tangent bundle. Differential dissipativity is connected to incremental stability in the same way as dissipativity is connected to stability. It leads to a natural formulation of differential passivity when restricting to quadratic supply rates. The paper also shows that the interconnection of differentially passive systems is differentially passive, and provides preliminary examples of differentially passive electrical systems.
