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 ▲]

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.

Water flow in the plant continuum is thought to be controlled by the leaf, xylem and the root radial conductances. Leaf conductance is widely recognized as the master control in the system as it can act as a switch in the water flow, even under high transpiration demand. The control of the stomatal aperture by the plant has been the object of numerous research projects since decades and different models have been developed to study stomatal regulation. The plant hormone abscisic acid (ABA) produced in the leaves acts as an endogenous signal triggering stomatal closure, but is also thought to act as a long distance signal that is produced by roots experiencing water deficit. However, the relative contributions of leaf-supplied ABA, root-supplied ABA and xylem water potential in the regulation of water flow remains a matter of controversy. Using a novel functional structural plant model (PlaNet-Maize-ABA), we report here a first attempt to explicitly simulate ABA production, degradation, translocation in all plant organs and their effect on the transpiration flow.

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 ▲]

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 ▲]

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. [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.

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 ▲]

Sugar-based biosurfactants such as xylose-derived bolaforms have interesting properties, for example high biocompatibility and biodegradability which make them potential useful molecules in the pharmaceutical and cosmetic fields. Until now, no detailed analyses of the physico-chemical properties of these compounds have been undertaken. Two symmetrical D-xylose-based bolaforms were chemically synthesized where the two xylose heads are linked via an acetal link to a hydrocarbon chain containing 18 carbon atoms and an unsaturation. The two bolaforms differ only by their anomeric configuration: or The bolaform exhibits interfacial properties at the air-water interface which is not the case for the . FTIR spectroscopy showed that the interactions between the bolaform and POPC, a model phospholipid, involve the carbonyl groups of the phospholipid [less ▲]

Risk factors for atrial fibrillation (AF) and pathological ventricular tachyarrhythmias (VTA) have been suspected in equids, however little epidemiologic data exists. The aim of this study was to determine risk factors for AF and VTA in a large equine population. Case files of 3499 equids admitted to the internal medicine department of the Liege University Equine Teaching Hospital between 1994 and 2011were reviewed. Amongst them, 495 horses with a suspicion of a cardiac abnormality underwent ECG and echocardiography. After calculation of prevalence of AF and VTA, we tested whether breed (chi-square test) or gender, age, body weight (BW) and presence of other cardiac diseases (logistic regressions) were risk factors (significance set at p<0.05). In the studied population, prevalence of AF was high (2.3%), whereas prevalence of VTA was low (0.7%). Warmbloods and standardbreds were significantly overrepresented in AF cases. High BW was a risk factor for AF (OR=3.54; CI=1.67-7.49), whereas age was not. No effect of breed, age or BW was demonstrated for VTA. AF was observed significantly more frequently in horses presenting with moderate to severe mitral regurgitation (MR), tricuspid regurgitation, and pulmonary regurgitation, and VTA was significantly more frequent in horses with MR. Several previously suspected but not statistically demonstrated risk factors of AF were confirmed in this study and horses presenting valvular disease could be at increased risk of developing AF and VTA.

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 ▲]

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 ▲]

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°.

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 ▲]

Using machine learning based models in clinical applications has become current practice and can prove useful to provide information at the subject’s level, such as predicting an (early) diagnosis or monitoring the evolution of a disease. However, the performance of these models depends on the choice of a biomarker to detect the presence or absence of a disease. Choosing a biomarker is not straightforward, especially in the case of Parkinson’s disease when compared to healthy subjects. In the present work, we investigated the mental imagery of gait as a biomarker of Parkinson’s disease and showed that the signal in the mesencephalic locomotor region during the mental imagery of gait at a comfortable pace can discriminate significantly between idiopathic Parkinson’s disease patients and healthy subjects. Although there is room for improvement, the results of this preliminary study are promising. [less ▲]

Schizophrenic patients and their first-degree relatives suffer from cognitive deficits in different area (memory, executive, attentional and language functions) which allows us to consider these deficits as endophenotypes of schizophrenia. Schizophrenic patients also suffer from a lack of autobiographical memory and instability of identity: our study aims to determine whether this deficit and this instability are endophenotypes of schizophrenia. In order to reach this objective, we evaluated first-degree relatives. The results show that first-degree relatives suffer from cognitive deficits but, contrary to our hypotheses, not any deficit of specificity or instability of identity have been highlighted among these parents.

HD 195592 is an O-type supergiant star, known as a well-established runaway. Recently, a Fermi γ-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 195592 has been reported. Our goal is to explore a scenario where HD 195592 is the counterpart of the Fermi γ-ray source. The high-energy emission would be inverse Compton radiation produced in the bowshock of the runaway star. We calculate relativistic particle energy losses and the resulting radiation from the bowshock of HD 195592 and show that the latter is compatible with the detected γ-ray emission. We conclude that the Fermi source 2FGL J2030.7+4417 might be produced, under some energetic assumptions, by inverse Compton up-scattering of infrared photons from locally heated dust. HD 195592 might therefore be the very first object detected belonging to the category of γ-ray emitting runaway massive stars, whose existence has been recently predicted. [less ▲]

Background: Bromocresol green method (BCG) is routinely used in veterinary laboratories to measure albumin. A good agreement between BCG and electrophoresis (SPE) in healthy domestic animals is reported. However, in human medicine, at low albumin and high globulin concentrations, BCG also binds to α- and β-globulins fractions. Surprisingly, there is no recent literature evaluating the BCG method in diseased domestic animals. Objective: The purpose of the present study was therefore to compare the serum albumin values obtained by SPE and BCG in canine and equine patients. Methods: Albumin measured by BCG and SPE was compared in the serum from 30 canine and 30 equine patients. Results: Good correlation was found (Spearman´s rho rs = 0.91 in dogs and 0.84 in horses). However, Altman and Bland analysis of results showed a positive bias of BCG with SPE (3.41 g/l in horses and 0.41 g/l in dogs) that increased when only hypoalbuminemic patients were considered (4.17 g/l in horses and 1.31 g/l in dogs). Conclusion: Results confirm that, despite good correlation, BCG method tends to overestimate albumin, especially in hypoalbuminemic patients. This is particularly evident in horses. [less ▲]

This paper focuses on the sizing of solar combisystems with adsorption seasonal storage to target autonomous solar space heating. Two main configurations of the combisystem are simulated, including one or two tanks. The influence of the seasonal storage on the sizing of the tanks is also discussed. Results show that performances of the system with two tanks are better (2 to 4 % with seasonal storage) but some improvements should be possible for the single tank configuration. The sizing of the sensible storage is nearly independent of the solar collectors area if there is a seasonal storage. The sensible storage size increase with the collectors area without adsorption storage. The analysis is conducted in simulation using the TRNSYS program. [less ▲]

Les populations de sangliers augmentent en nombre et étendent leur aire de répartition un peu partout en Europe. En Wallonie, la population de sangliers a quadruplé en 30 ans. Plusieurs études se sont penchées sur le sujet et les raisons de cette augmentation concernent souvent l’influence du climat. Grâce aux différents suivis réalisés par le DEMNA, les déplacements au sein des populations de sangliers sont mieux compris. L’article se penche d’abord sur le potentiel de dispersion du sanglier en se basant sur les données de bagage de marcassins. Deux variables sont analysées : la distance parcourue dans le cadre de la dispersion natale (mouvement à sens unique à partir du site de naissance d’un individu jusqu’à son site de première reproduction) et le taux de cette dispersion natale. Quelques résultats provenant d’une étude génétique sont également présentés. Le génotypage de 1153 sangliers répartis sur l’ensemble de la Wallonie a mis en évidence quatre sous-populations génétiquement homogènes. Parallèlement à l’augmentation de la taille de ses populations, le sanglier a vu son aire de distribution s’accroître en Wallonie. Un suivi par enquête a été réalisé auprès des conseils cynégétiques et des agents du DNF pour mieux comprendre l’expansion géographique observée. Une première phase de l’enquête visait à retracer l’expansion géographique du sanglier en Wallonie. La seconde phase consistait à réaliser un état des lieux sur la situation actuelle de la distribution du sanglier en périphérie du sillon Sambre-et-Meuse. [less ▲]

Quatre prises d’eau exploitées à Arquennes (Belgique) sont contaminées par le nitrate. Leurs bassins d’alimentation sont situés en zone agricole caractérisée par un sol limoneux sur un aquifère sableux. Depuis 2004, ces bassins servent de site pilote dans le cadre de l’évaluation du Programme de Gestion Durable de l’Azote (PGDA), transposition de la Directive « Nitrates » en droit wallon. Les modèles numériques SWAT et FEFLOW ont permis de simuler les flux d’eau et de nitrate depuis la surface jusqu’aux galeries. Après calibrage et validation des modèles (sur la base d’une caractérisation du sol et du sous-sol et de traçages en milieux saturé et non saturé), plusieurs scénarios de pratiques agricoles ont été simulés afin de prédire l’évolution qualitative des eaux. L’expérience d’Arquennes a démontré que le recours au couplage SWAT / FEFLOW permet de proposer des solutions environnementales réalistes pour atteindre les objectifs fixés par la DCE. [less ▲]

Alopecia areata (AA), an autoimmune disease affecting anagen stage hair follicles, is associated with polymorphisms in immune-related genes and with decreased number of CD4+ CD25+ T regulatory cells (Treg). Treg function is modulated by the forkhead box protein 3 (FOXP3) transcription factor and by inducible costimulator (ICOS), through interaction with the relative ligand, ICOSLG, whose genes are polymorphic. The aim of the study was to investigate whether specific single nucleotide polymorphisms (SNPs) of the rs2294020 FOXP3 and/or rs378299 ICOSLG genes may be associated with AA. A case-control study was performed in 120 AA patients and 84 controls. SNPs were analyzed by gene sequencing. FOXP3 and ICOSLG gene expressions were analyzed by real-time PCR. Increased frequencies of the genotype carrying the FOXP3 rs2294020-3675(A) [P = 0.002, OR (95 % CI): 2.55 (1.2-2.7)] or the ICOSLG rs378299-509(C) [P = 0.01, OR (95 % CI): 2.21 (1.1-2.6)] allelic variants were observed in AA patients than in controls. The genotype carrying the combination of the FOXP3 rs2294020-3675(A) and ICOSLG rs378299-509(C) allelic variants with the HLA DQB1*03 allele was more frequently present in AA patients than in controls (P = 0.04). The presence of the FOXP3 rs2294020-3675(A) or the ICOSLG rs378299-509(C) allelic variant was associated with reduced relative gene expression in AA patients. These data suggest that rs2294020 SNP of FOXP3 gene and rs378299 SNP of ICOSLG gene are associated with AA and with a reduced expression of the FOXP3 and ICOSLG genes in alopecia patients. [less ▲]

OBJECTIVES: This study evaluates the impact on voice of a 2-hour reading task between 70-75 dB(A) in 16 normophonic and 16 dysphonic female teachers with vocal nodules. METHODS: Objective measurements (acoustic analysis, voice range measurements, aerodynamic measurements) and subjective self-ratings were collected before the task and every 30 minutes during the reading to determine the voice evolution in both groups. RESULTS: Fundamental frequency, lowest frequency, highest frequency (F-High), highest intensity and intensity range increase through the reading, whereas Shimmer decreases. Maximum phonation time decreases after 30 minutes. Estimated subglottal pressure (ESP) and sound pressure level increase during the first hour. Afterwards, ESP decreases. Self-ratings worsen through time. When comparing the normophonic and the dysphonic teachers, self-ratings reveal more complaints in the dysphonic group. Few differences in objective measurements are found between both groups: normophonic teachers show lower ESP, higher F-High and greater frequency range. CONCLUSIONS: Frequency modifications from acoustic analysis and voice range measurements suggest an increased laryngeal tension during vocal load, while subjects perceive a worsening of voice. Aerodynamic parameters depict first a deterioration of voice efficiency and then an adaptation to the prolonged reading. The comparison between both groups shows a discrepancy between objective measurements and self-ratings, suggesting that both approaches are necessary to have a complete view of vocal load effects. Surprisingly, both groups behave similarly through vocal load, without more or quicker deterioration of voice in the dysphonic group. [less ▲]

Background: Heart transplantation remains to date the only definite treatment option for end-stage heart diseases. Currently only heart procured from brain death (DBD) donors are used. Combined with an increasing demand, the constant heart graft shortage leads to an increase of deaths on cardiac transplantation waiting lists. The use of hearts procured after donation after circulatory death (DCD) could help to partly decrease the heart graft shortage. The aim of this study was to evaluate the potential increase of heart graft pool by development of DCD heart transplantation. Methods: The authors retrospectively reviewed their local donor database for the period 2006-2011, and screened the complete controlled DCD donor population for potential heart donors, using the same criteria as for DBD heart transplantation. The acceptable warm ischemic time (WIT) was limited to 30min from life support withdrawal to aortic cannulation. Results: During the analyzed timespan, 177 DBD and 70 DCD were effectively performed. From the 177 DBD, a total of 70 (39.5%) hearts were procured and transplanted locally or in another center. Out of the 70 DCD, 8 (11%) donors fulfilled the criteria for heart graft procurement and had a WIT of less than 30 minutes. During the same period, 82 patients were newly listed for heart transplantation, of which 53 were transplanted, 20 died or were unlisted, and 9 were still awaiting transplantation. Conclusions: Based on our database and a WIT of less than 30min, it could be estimated that 11% of the DCD might be heart graft donors, representing a 11% increase in heart graft procurement, as well as potential reduction of the deaths on the waiting list by 40%.

Age-related difficulties have been reported on proactive control whereas reactive control seems to remain intact (Braver, Gray, & Burgess, 2007; Braver, 2012). This study investigated the potential influence of speed of processing abilities on the age-related decline in proactive control. We used a working memory recognition paradigm involving proactive or reactive cognitive control by manipulating the interference level across items. 80 young adults (18-29 years old) and 80 healthy older adults (60-89 years old) were included. The main results revealed significant effects of age on sensitivity to interference. As expected, reactive control performance remained intact with aging (similar interference effect in the two groups). In contrast, we observed a larger interference effect in the proactive condition in aging. Finally, when the groups are matched according to their processing speed (assessed by the Code task of the WAIS III, with both younger and older adults having a score comprised between 60 and 93), the effect of age on sensitivity to interference disappeared. In other words, when younger and older adults had similar speed of processing abilities, no age-related proactive control decline was observed. In conclusion, beyond the fact that this study confirms the selective age-related decline in proactive control, it also indicates that speed of processing, a measure considered as reflecting the integrity of cognitive functioning during aging (Salthouse, 1996), influences the efficiency of proactive control in that population.

Alfalfa (Medicago sativa L.) is a high quality forage which has been used worldwide. The superiority of alfalfa lies in its high yield, high protein content and high digestibility. The aim of this study was to develop a simple, fast and non-destructive method, named Near Infrared Spectroscopy (NIRS) to determinate alfalfa quality. To realize this study, alfalfa samples were obtained from Mănăştur Experimental Station – Farm Cojocna in 2008–2009, in one experiment carried out using randomization blocks design with two experimental factors (mineral fertilization and period of harvest). Alfalfa quality was first determinated on 48 samples by classical analyses: crude protein CP (AOAC, 1990), crude fiber CF (Fiber Cap, FOSS, DK) and in vitro organic matter digestibility OMDrt (DeBoever, 1986). Then the samples were scanned by NIRS. Calibration models were performed by PerkinElmer Spectrum Quant + 4.21 program (USA) on the 48 samples determinated by classical analysis. The results showed fully confirmed by acceptable coefficients of determination and standard error of cross-validation (R2=0.96 for CP, 0.94 for CF, 0.98 for OMDrt and SECV=0.77 for CP, 1.35 for CF, 1.13 for OMDrt). Successful results for prediction of other 176 alfalfa samples were then obtained using these calibration models: SEP=0.869 for CP, 1.058 for CF, 1.058 for OMDrt). The highest CP and OMDrt values of alfalfa were obtained in bud stage (22.0% and 66.0% respectively). While for CF, the highest content was registered in the seed formation stage (46.0%). The NIRS technique offers us the possibility to determinate rapidly and easily Romanian alfalfa important parameters, but the system could also be used for the determination of other constituents.

This paper presents a two-dimensional model of tension levelling using the Arbitrary Lagrangian Eulerian (ALE) approach. During the simulation, the ALE mesh remains globally fixed along the rolling direction. Therefore, the required number of finite elements is much smaller than in the Lagrangian case and smaller CPU times are obtained for the same accuracy on the results. The ALE model is first validated against a classical equivalent Lagrangian model. Then, both sets of numerical results are compared to experimental measurements from the pilot mill of ArcelorMittal Maizières R&D. [less ▲]

Nowadays in agriculture, new analytical tools based on spectroscopic technologies are developed. Near Infrared Spectroscopy (NIRS) is a well known technology in the agricultural sector allowing the acquisition of chemical information from the samples with a large number of advantages, such as: easy to use tool, fast and simultaneous analysis of several components, non-polluting, non-invasive and non destructive technology, and possibility of online or field implementation. Recently, NIRS system was combined with imaging technologies creating the Near Infrared Hyperspectral Imaging system (NIR-HSI). This technology provides simultaneously spectral and spatial information from an object. The main differences between NIR-HSI and NIRS is that many spectra can be recorded simultaneously from a large area of an object with the former while with NIRS only one spectrum was recorded for analysis on a small area. In this work, both technologies are presented with special focus on the main spectrum and images analysis methods. Several qualitative and quantitative applications of NIRS and NIR-HSI in agricultural products are listed. Developments of NIRS and NIR-HSI will enhance progress in the field of agriculture by providing high quality and safe agricultural products, better plant and grain selection techniques or compound feed industry’s productivity among others.

Between 2006 and 2007, L’Association have published the three issues of L’Éprouvette. These are, among other, illustrated by thirty-four images that are hugely enlarged fragments of comic’s panels. By comparing this with similar realizations (the exhibition Bande dessinée et Figuration narrative, the column « Cases mémorables » of the journal Les Cahiers de la bande dessinée), this paper asks about what it means reproducing comics’ fragments. It also tries to analyze the role played by these images within the journal and the links with the rest of the content. Endlessly, still by putting it in prospect with the realizations here above mentioned, it tries to see in what extent these images reflect a certain view about the history of the comic. [less ▲]

Introduction: Patellar tendinopathy, often remain rebel to conservative treatments. Researches have specifically demonstrated the platelets action as mediator and/or enhancer of tissue healing. The aim of our study was to investigate the effect of 1 injection of PRP in patients suffering from chronic patellar tendinopathy. Methods: Patients performed imaging (US and MRI) and functional assessments, and a clinical examination using an algometer, before treatment and 6 weeks after PRP treatment. They were also invited to answer to questionnaire relative to pain and functional status. PRP was obtained from autologous blood using an apheresis system (COM.TEC, Fresenius). The injection of 6mL of PRP was realised without local anaesthesia into the proximal insertion of the patellar tendon. A 48h rest-time was recommended after infiltration. Afterwards, a submaximal eccentric reeducation was initiated 1 week after infiltration 3 times a week during 5 weeks. In case of pain, anti-inflammatory drugs were prohibited and patient were encouraged to take class I or II painkillers. Results: At this time, 10 patients with patellar tendinopathy were included in our study. Pre-injection tests revealed pain of the upper part of the patellar tendon just below the patella, associated with loss of function. Imaging exams confirmed diagnosis. Six weeks post-injection, the clinical status was improved in all patients, with a significant decrease of algo-functional scores. The pain reported during functional assessments was decreased (in particular for the eccentric actions), yet no significant improvement of physical performances was observed. We found no significant differences between imaging exams before and 6 weeks after PRP injection. Conclusion: One in situ injection of PRP clinically improved patients with patellar tendinopathy 6 weeks after treatment. All the 10 patients reported a decrease of pain during day-life and through physical activities. However nor functional performances neither imaging were improved. [less ▲]

This study tests the controversial hypothesis that word naming difficulties may arise in individuals as young as their 50s. Participants of 25-35, 50-59, 60-69 and above 70 years of age were given a picture naming task. To uncover subtle naming difficulties, correct naming latencies were analyzed, in addition to accuracy. Moreover, in order to control whether the expected slower naming latencies could be due to a general slowing affecting all cognitive tasks, participants were also given an odd/even judgment task to assess cognitive processing speed. In participants in their 50s, we found subtle naming difficulties revealed by longer naming latencies, unaccompanied by any decrease in naming accuracy. The age-related naming disadvantage increased with age with the onset of naming errors. Thus, in adults in their 60s and their 70s, the results showed both a decrease in accuracy and an increase in correct naming latencies. Moreover, the increase in naming latencies remained significant even after controlling for odd/even judgment latencies, suggesting a degradation specific to the picture naming task. We assumed that these slower latencies may result from a language-specific impairment. [less ▲]
