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. [less ▲]

The long-term survival of the Endangered bonobo (IUCN, 2012) will depend on well thought out conservation programmes that need to be built both upon the species’ ecological requirements and local socio-economics realities. Yet there is still a lot to find out, including information on the species geographical distribution. In 2005, the presence of a western population was confirmed in the forest-savannah mosaic in the south-western part of the Lake Tumba Landscape. With the exception of an early study carried out in Lukuru, the species is mainly known from lowland rainforest research sites in the Cuvette Centrale. The western forest-savannah mosaic is an ecotone with a marked seasonal pattern, a high variability of habitats and monthly variations in fruit production. All this leads to spatio-temporal variation of food availability. In order to increase studies and monitoring of this unique population, WWF initiated a habituation process of two groups of bonobos 6 years ago. The groups are now semi-habituated, making the collection of direct daily observations possible. Our objective is to describe the behavioural strategies developed by this population in order to cope with spatio-temporal variations of food availability. This will be approached by identifying daily activity, ranging and grouping patterns, in order to understand how they affect social structure. It should also allow us to define the use of savannahs. Our findings will help determine specific conservations measures for this endangered species. [less ▲]

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. [less ▲]

The saddle gall midge, Haplodiplosis marginata (von Roser, 1840) is a univoltine pest of cereals which occurs in Europe. The larvae feed on stems and attractive saddle-shaped depressions, driving to important yield losses when the galls are numerous. After 40 years without any reporting, large populations of H. marginata and important damage have been observed since 2010 in wheat crops in Belgium, especially in the Flemish Polders where clay soils and intensive farming of cereals favour heavy infestations. According to some research conducted in the 1960s during the last outbreak, oat (Avena sativa L.) is known to be one of the less favourable hosts to the saddle gall midge. Our study was performed in order to assess the host sensitivity of three oat varieties currently grown in Belgium: EVITA, EFFEKTIV and FREDDY. Therefore, oat varieties were sown on infested soil in two separate enclosures in a glasshouse. In the first enclosure, only the three oat varieties were grown; in the second one, these three oat varieties were grown together with two varieties of spring wheat: GRANNY and KWS CHAMSIN. Two parameters were measured: the percentage of leaves with laid eggs, and the number of galls per stem. The percentage of leaves with eggs showed that the infestation was significantly lower on oats when they were in presence of wheat. The egg infestation was also significantly higher on wheat than on oat, which means oat is a much less favourable host plant than spring wheat for egg laying. Oat varieties were significantly different from each other regarding the number of galls per stem, but with very little damage compared to wheat. The FREDDY variety even seemed to be completely resistant to saddle gall midge, as no galls were observed although there was a similar percentage of leaves with eggs for the three oat varieties. Cropping oat could thus contribute to reduce infestations of H. marginata. [less ▲]

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. [less ▲]

Background: Measurement of CSF albumin aids diagnosis in human medicine but technical difficulties related to its low CSF concentration prohibit its routine use in veterinary medicine. High-resolution electrophoresis (HRE) has been described but often results in non-interpretable integration profiles preventing albumin determination. Fraction quantification using HRE may be more precise after concentration (cHRE) using a membrane microconcentrator technique but has not been evaluated in CSF with total protein levels below 20mg/dL. Immunoturbidimetry is routinely used for human CSF albumin measurement and was recently applied on canine samples with encouraging results. Objective: The purpose of this study was to compare HRE (including the use of a concentration step) and immunoturbidimetric assay for the measurement of albumin levels in normal canine CSF. Methods: 30 CSF specimens from 15 healthy dogs were evaluated. CSF total protein was measured by the pyrogallol red methoda and CSF albumin was determined by HREb (n=15), cHREc (n=30) and immunoturbidimetric assayd (n=30). Validation of the human immunoturbidimetric assay was performed using a purified canine albumin standarde. Results: Mean CSF total protein was 17.5 (range 7-39) mg/dL. HRE integration profiles were non-interpretable in all unconcentrated specimens. However, clear distinction of the major protein fractions was achieved for all cHRE specimens. CSF albumin levels were measureable in 29/30 specimens using immunoturbidimetry. Excellent correlation (Pearson r=0.92, p<0.001) was found between the two techniques. Conclusion: Immunoturbidimetry and cHRE may be used for routine measurement of CSF albumin. [less ▲]

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. [less ▲]

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.

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). [less ▲]

Introduction: CD22 is expressed on most B-non-Hodgkin lymphomas (NHL); inotuzumab ozogamicin (INO) is an anti-CD22 antibody conjugated to calicheamicin. This study evaluated the safety and tolerability of INO plus R-CVP in patients (pts) with relapsed/refractory CD22+ B-NHL. Efficacy data were also collected. Methods: Part 1 of this open-label study identified a maximum tolerated dose (MTD) of INO 0.8mg/m,2 on day 2 plus R-CVP (rituximab 375mg/m,2 cyclophosphamide 750mg/m,2 and vincristine 1.4mg/m,2 on day 1; prednisone 40mg/m,2 on days 1-5) every 21 days. Subsequently, pts were enrolled in the MTD confirmation cohort (part 2, n = 10), which required a dose-limiting toxicity rate of <33% in cycle 1 and <4 pts discontinuing prior to cycle 3 due to an adverse event (AE) in the MTD expansion cohort (part 3, n = 22), which explored preliminary activity. Results: Parts 2 and 3 enrolled 32 pts: 16 pts with diffuse large B-cell lymphoma, 15 with follicular lymphoma and one with mantle cell lymphoma. Median age was 64.5 years (range 44-81 years); 34% of pts had 1 prior regimen, 34% had 2, 28% had ≥3 and 3% had none (median 2; range 0-6).Median treatment duration was five cycles (range 1-6). Part 2 confirmed the MTD as standard dose R-CVP plus INO 0.8mg/m,2; 2/10 pts had a dose-limiting toxicity (grade 3 increased ALT/AST, grade 4 neutropenia requiring G-CSF). One pt discontinued because of an AE prior to cycle 3. Common treatment-related AEs were thrombocytopenia (78%), neutropenia (66%), fatigue (50%), leukopenia (50%), nausea (41%) and lymphopenia (38%); common grade 3/4 AEs were neutropenia (63%), thrombocytopenia (53%), leukopenia (38%) and lymphopenia (31%). There was one case of treatment-related fatal pneumonia with grade 4 neutropenia. Ten pts discontinued treatment due to AEs; thrombocytopenia/delayed platelet recovery was the leading cause (grade 1/2, n = 6; grade 3/4, n = 3). Objective response rate (ORR) was 77% (n = 24/31 evaluable pts), including 26% (n=8/31) with complete response (CR); three pts had stable disease. Of the pts with follicular lymphoma, ORR was 100% (n = 15/15), including seven pts with CR. Of the pts with diffuse large B-cell lymphoma, ORR was 60% (n = 9/16), including one pt with CR. Conclusions: Results suggest that INOplus R-CVP has acceptable toxicity and promising activity in relapsed/refractory CD22+ B-NHL. The most common grade 3/4 AEs were hematologic. Follow-up for progression-free and overall survival is ongoing. [less ▲]

To better understand the agricultural landscapes evolution becomes an essential preoccupation and, for this, it is needed to take into account the sediments deposition, in a distributed way. As it is not possible in practice to study all terrestrial surfaces in detail by instrumenting sectors to obtain data, models of prediction are valuable tools to control the current problems, to predict the future tendencies and to provide a scientific base to the political decisions. In our case, a landscape evolution model is needed, which aims at representing both erosion and sedimentation and dynamically adjusts the landscape to erosion and deposition by modifying the initial digital elevation model. The Landsoil model (Landscape design for Soil conservation under soil use and climate change), among others, could fulfil this objective. It has the advantage to take the soil variability into account. This model, designed for the analysis of agricultural landscape, is suitable for simulations from parcel to catchment scale, is spatially distributed and event-based. Observed quantitative data are essential (notably to calibrate the model) but still limited. Particularly, we lack observations spatially distributed on the watershed. For this purpose, we choose a watershed in Belgium (Wallonia) which is a 124 ha agricultural zone in the loamy region. Its slopes range from 0% to 9%. To test the predictions of the model, comparisons will be done with: - sediment measurements which are done with water samplings in four points on the site to compare the net erosion results; - sediment selective measurements (depth variation observed along graduated bares placed on site) to compare the erosion and deposition results; - very accurate DSM’s (6,76 cm pixel resolution X-Y) obtained by the drone (Gatewing X100) each winter. Besides planning what the landscape evolution should be, a revision of the soil map (drew in 1958) is organized to compare with the past situation and establish how the landscape moved in 50 years. The first results of the sediment measurements and of the pictures of the drone will be showed in the presentation. [less ▲]

CADY is a cell-penetrating peptide spontaneously making non-covalent complexes with short interfering RNAs (siRNAs) in water. Neither the structure of CADY nor that of the complexes is resolved. We have calculated and analyzed 3D models of CADY and of the non-covalent CADY–siRNA complexes in order to understand their formation and stabilization. Data from the ab initio calculations and molecular dynamics support that, in agreement with the experimental data, CADY is a polymorphic peptide partly helical. We calculated and compared several complexes with peptide/siRNA ratios of up to 40. The initial binding of CADYs is essentially due to the electrostatic interactions of the arginines with siRNA phosphates. Due to a repetitive arginine motif (XLWR(K)), CADYs can adopt multiple positions at the siRNA surface. Nevertheless, several complex properties are common: an average of 14 ± 1 CADYs is required to saturate a siRNA. The 40 CADYs/siRNA that is the optimal ratio for vector stability always corresponds to two layers of CADYs per siRNA and the peptide cage is stabilized by hydrophobic CADY–CADY contacts. The analysis demonstrates that the hydrophobicity, the positive charges and the polymorphism of CADY are mandatory to make stable the CADY–siRNA complexes. [less ▲]

The recent UNESCO Recommendations on the historic hurban landscape insist on the opportunity to "shift from an emphasis on architectural monuments primarly" towards "a landscape approach" including "the broader urban context and its geographical setting", to understand historic urban landscape "as the result of a historic layerling, and to create new tools to adress this vision". Along this line of thought of thought, the proposed approach expands the traditional contents of architectural guides, providing keys to reconsider and evaluate the listed works' contribution to the evolution of their immediate surrounding, to the urban structure as a whole, up to the territorial scale. Moving from a design-oriented perspective and using the methods of urban morphology, the work consists mainly of set of original schemes, maps and drawings of Liège and its neighborhoods, as means to reveal the urban structure, its layerling over time, and the role of architectural heritage in clarifuing, enhancing, or even degrading the coherence of the urban artifact. Halfway between popular and scholarly literature, the forthcoming guides aim to become at both times "handbooks for city decoding" and blueprints for urban design. Providing tools lo read, comprehehen, and appreciate the part played by built heritage in a city's evolution and in the shaping of our daily environment helps to understand urban environments as a process bearing the overlapping influences of many experiments, partially implemented plans, competing visions and contradictory ideas. As a result, both the ordinary and specialized audience can possibly raise their awareness and perception of modernist architecture's legacy, but also learn how certain qualities were achieved and how certain local issues came about, acquiring relevant critical keys to take part as stakeholders or designers in the debate over the future city.

Many white biotechnology bioprocesses apply techniques from chemical engineering based on bioreactors with mechanical stirring system commonly employed in pharmaceutical sector, food industry or energy field (Dasilva, 2004). As in chemical engineering, scale-up of these bioprocesses induces physicochemical constraints that affect physiological pathways and decrease performances. In this context, it is essential to think new bioprocesses better suited to physiology of microorganisms, minimizing physicochemical constraints. The aim of this work consists to use stainless steel structured packing (SSP) with high specific area (500-750 m²/m³) as inert support for biomass immobilization in order to produce high added value biomolecules. These bioreactors are biocatalysts in which microbial system is immobilized biomass on the form of a biofilm performing bioconversion of a substrate into a specific product (Rosche, 2009). In this study, an experimental setting containing a SSP reproduces solid-state fermentation (SSF) like conditions. Two well known microorganisms for their ability to form biofilm and secrete metabolites are tested in the experimental setting : Bacillus subtilis for its lipopeptides and Aspergillus oryzae for its glucoamylase. Effectiveness of the bioprocess in term of dynamic of the excretion of the target biomolecule is compared with a classical submerged culture (SmF). For lipopeptides production from B. subtilis, SSP is located in a 20L bioreactor continuously aspersed by liquid medium required to the growth of the biofilm. In the case of A. oryzae, the SSP is partially immerged in a 250 mL shake flask. X-ray tomography of the SSP allows non-invasive visualization and quantification of biofilm repartition inside the support. Implementation of SSP permits almost total immobilization of biomass on the form of a mono-species biofilm to the detriment of the liquid phase. Processing of images obtained by X-ray tomography of the SSP provides relevant information for the optimization of the bioprocess. For both microorganism species, results indicate the influence of parameters such as hydrodynamics, aeration rate and microorganism specificity, on the biofilm morphology inside the support and the performances of the bioprocess. SSF-like conditions in the experimental setting lead to technologic progress, such as absence of foam formation, persistence of the microbial system, and improve the dynamic of metabolites excretion compared with conditions imposed by the submerged culture. Further experiment will consider hydrodynamics aspects and amount of carbon source on effectiveness of the bioprocess. [less ▲]

This paper presents an experimental study of the quasi-static mechanical behavior of TA6V titanium alloy. Different monotonic tests were carried out in several orientations in the plane of the sheet in order to characterize the anisotropy and the tension-compression asymmetry exhibited by the material. Initial yielding is modeled by the phenomenological CPB06 criterion and Voce's isotropic hardening is used to describe its evolution. The simulation of a deep-drawing process is performed using the proposed constitutive modeling and compared with experimental data. [less ▲]

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. [less ▲]

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. [less ▲]

Post-combustion CO2 capture in power plants is one of the most mature technologies for a short-term and large-scale decrease of CO2 emissions while simultaneously addressing the growing global energy demand. CO2 is chemically absorbed in an amine solvent that can be regenerated at higher temperature, producing a pure CO2 stream. However, the large impact of this technology on the power plant efficiency and the environmental penalty are the main drawbacks for large-scale implementation. In this work, an innovative approach combining process modeling and evaluation of the environmental penalty due to amine degradation is presented. Based on experimental results, the kinetics of solvent oxidative and thermal degradation is estimated and included in the process model developed in Aspen Plus. Using this model, the influence of operating parameters like the oxygen concentration in the flue gas or the solvent regeneration pressure is studied. This model is a first step for a multi-objective optimization of the CO2 capture process, assessing both energy and environmental penalties of this technology. [less ▲]

The Second Harmonic Generation (SHG) response from Tyrosine-containing peptides at the air-water interface is presented. First, the quadratic hyperpolarizability of the aromatic amino acid Tyrosine obtained by Hyper Rayleigh Scattering is reported, demonstrating its potentiality as an endogenous molecular probe for SHG studies. Then, the single Tyrosine antimicrobial peptide Mycosubtilin is monitored at the air-water interface and compared to another peptide, Surfactin, lacking a Tyrosine residue. Adsorption kinetics and polarization analysis of the SHG intensity for the peptide monolayers clearly demonstrate that the SHG response from Mycosubtilin arises from Tyrosine. Besides, it confirms that indeed Tyrosine can be targeted as an endogenous molecular probe. [less ▲]

This paper presents a new design of a planar solar concentrator for space applications focusing on two spatially separated PV cells, allowing independent control of output power of each cell. It has the advantages of both spectral splitting and solar concentration by the combination of a blaze transmission diffraction grating and a flat cylindrical Fresnel lens. An optical optimization has been realized and two variations of configuration have been developed to improve tracking tolerance: first, a design completed by secondary reflective concentrators and second, a symmetrical configuration composed of two lenses. First numerical results are presented, highlighting the possibility to design a concentrator at about 10×, with an electrical output power about 290W/m² lens and less than 10% losses for tracking errors lower than ±0.9°.

La décision de la commission européenne de mettre fin en 2015 à la politique des quotas laitiers mise en place en 1984 va vraisemblablement bousculer le paysage laitier européen mais aussi mondial. Plus que jamais les grands pays producteurs (Etats-Unis, Canada, France, Allemagne, Pays-Bas, Irlande, Nouvelle-Zélande) vont dans ce contexte de libéralisation et de globalisation de « l’or blanc » se livrer une concurrence effrénée dans laquelle la majorité des producteurs n’auront que peu ou rien à dire. L’augmentation attendue de la production laitière mondiale (15 milliards de litres par an entre 2010 et 2020) résulte bien entendu de l’augmentation de la population mondiale (3,1 milliards entre 1970 et 2010 auxquels s’ajouteront 2 milliards de plus en 2050) mais également du fait que davantage de personnes en Extrême et Moyen-Orient, en Amérique du Sud et en Afrique du Nord consomment davantage de lait et de produits dérivés. L’enjeu pour la majorité des éleveurs européens ou non va être de réduire les coûts liés à la production laitière en (1) optimisant les ressources alimentaires, (2) en améliorant la santé mammaire, (3) en augmentant la longévité des vaches, (4) en réduisant la fréquence des maladies métaboliques, locomotrices ou infectieuses et (5) en améliorant la fécondité. L’amélioration de la fécondité passe définition oblige par la réduction de l’âge du premier vêlage et de l’intervalle entre vêlages. Par gestion, il faut entendre dans un premier temps la quantification du problème et dans un second l’identification des diverses hypothèses diagnostiques qui en sont responsables. Les facteurs de nature alimentaire, thérapeutique, pathologique ou de gestion susceptibles de modifier l'évolution normale de chaque femelle depuis sa naissance jusqu'au moment de sa réforme sont de nature diverse. Ils concernent l'individu ou le troupeau. Ils sont directement ou indirectement responsables de leur fertilité et/ou de leur fécondité. Leurs effets se manifestent de manière isolée ou synergique. Ils concernent aussi bien les animaux que ceux qui en ont la responsabilité sanitaire ou de gestion. Ils sont de nature anatomique, infectieuse, hormonale, thérapeutique ou zootechnique. Par gestion de la reproduction, il faut entendre une approche épidémiologique, globale de l’infécondité qui en intègre les aspects spécifiques sans négliger pour autant les autres aspects qui ne lui sont pas directement liés. Par gestion de la reproduction, on peut aussi comprendre sa gestion hormonale à savoir le recours à des protocoles thérapeutiques de synchronisation des inséminations et donc des vêlages. L’une et l’autre approche s’inscrive dans le contexte d’une identification systématique des animaux à risque au travers d’un suivi mensuel de reproduction. Ce suivi est la clé de voûte d’une gestion de la reproduction. Au travers d’une démarche hypothético-déductive, la présente communication se propose de - quantifier les performances de reproduction au travers des ses principaux paramètres de fécondité et de fertilité : cette première étape est indispensable pour identifier la présence ou non d’un problème d’infécondité, - passer en revue et de manière aussi synthétique que possible les diverses hypothèses et donc les facteurs de risque responsables d’infécondité - proposer des stratégies curatives ou préventives, anti-infectieuses ou hormonales voire zootechniques pour limiter les conséquences de l’infécondité.

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. [less ▲]

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.

The binomial coefficient of two words u and v is the number of times v occurs as a subsequence of u. Based on this classical notion, we introduce the m-binomial equivalence of two words refining the abelian equivalence. The m-binomial complexity of an infinite word x maps an integer n to the number of m-binomial equivalence classes of factors of length n occurring in x. We study the first properties of m-binomial equivalence. We compute the m-binomial complexity of the Sturmian words and of the Thue-Morse word. We also mention the possible avoidance of 2-binomial squares. [less ▲]
