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.

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 ▲]

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 ▲]

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°.

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 ▲]

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.

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 ▲]

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 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 ▲]

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 ▲]

Risk factors for valvular regurgitations (VR) have been suspected in equids, but no extensive epidemiologic study has been performed in a large mixed equine population. Therefore, the aim of this study was to statistically test risk factors for VR in a large population of equids. Hospital records were reviewed for 3.499 equids, admitted at the internal medicine department of the Liege Equine Teaching Hospital between 1994 and 2011, aged ≥2 years, and which underwent thorough cardiac clinical evaluation. Of this population, 495 cases had ECG and echocardiography performed because of a clinical suspicion of cardiac disease. Chi-square test or logistic regressions (as appropriate) were used to test if breed, gender, age, body weight (BW), and co-existence of various cardiac diseases were risk factors for each VR. Moreover, the risk of development of congestive heart failure (CHF) was tested for each VR. Significance was set at p<0.05. Most of the studied animals were warmbloods, and observed prevalences were 4.4% for mitral regurgitation (MR), 2.1% for aortic regurgitation (AR), 1.7% for tricuspid regurgitation (TR), and 1.0% for pulmonary regurgitation (PR). Significant risk factors were male gender and increasing age for AR (OR=2.03, CI=1.07-4.94), and racehorses breed group and middle-age for TR (OR=4.36; CI=1.10-17.24). No effect of age or BW was demonstrated for MR. MR was the major valvular disease associated with atrial fibrillation (AF), ventricular tachyarrhythmia, PR and CHF. TR was also linked to AF, PR and CHF; but AR was not linked to CHF. In conclusion, several previously suspected risks factors for VR were confirmed statistically in this study and should be taken into account in health and athletic monitoring of horses presenting predisposing factors.

Additive manufacturing processes such as laser cladding (LC) or selective laser melting (SLM) appear very promising in view of an economic near-net-shape production – and also, in the case of LC, the restoration - of complex and (almost) fully dense parts from Ti alloys. Both techniques involve the melting of a metallic powder with a laser. In the SLM process, the metallic powder is deposited layer by layer in a powder bed and then molten locally according to the desired shape, whereas in LC, the metallic powder is directly projected onto a substrate through a nozzle coaxial with the laser beam. The present research aims at comparing Ti-6Al-4V samples processed by these two techniques with reference samples produced by electron beam melting (EBM), another well established additive manufacturing process (patented by Arcam AB Company) in which a powder bed is molten locally by means of an electron beam. In all three processes, the melt pool undergoes an ultrafast cooling and solidifies very rapidly once the beam has left the area, thus giving rise to strongly out-of-equilibrium microstructures. Yet, each one of these processes also has its own specificities e.g. in terms of scanning strategy and of working atmosphere (low vacuum vs. protective Ar flow). In the present work, the microstructures obtained by these three processes have been compared in details, with a particular attention for characteristics such as porosity, grain size, and the various phases present. Since epitaxial growth of the newly deposited layer on the material previously solidified has been shown [1, 2] to exert a strong influence on the microstructure and on the resulting mechanical properties, great care has been taken to study the microstructural anisotropy associated with each one of the three processes.

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 ▲]

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 ▲]

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 ▲]

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.

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 ▲]

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 ▲]

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.

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%.

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 ▲]

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.

Groundwater resources are increasingly used around the world as geothermal systems. Understanding physical processes and quantification of parameters determining heat transport in porous media is therefore important. Geophysical methods may be useful in order to yield additional information with greater coverage than conventional wells. We report a heat transport study during a shallow heat injection and storage field test. Heated water (about 50°C) was injected for 6 days at the rate of 80 l/h in a 10.5°C aquifer. Since bulk electric resistivity variations can bring important information on temperature changes in aquifers (water electric conductivity increases about 2%/°C around 25°C), we monitored the test with surface electric resistivity tomography and demonstrate its ability to monitor spatially temperature variations. Time-lapse electric images clearly show the decrease and then the increase in bulk electric resistivity of the plume of heated water, during respectively the injection and the storage phase. This information enabled to calibrate the conceptual flow and heat model used to simulate the test. Inverted resistivity values are validated with borehole electromagnetic measurements (EM39) and are in agreement with the temperature logs used to calibrate the parameters of the thermo-hydrogeological model for the injection phase. This field work demonstrates that surface electric resistivity tomography can monitor heat and storage experiments in shallow aquifers. These results could potentially lead to a number of practical applications, such as the monitoring or the design of shallow geothermal systems or the use of heated water to replace salt water in tracer tests.

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 ▲]

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 ▲]

We present a summary of the properties of white dwarf stars, beginning with a brief reminder of their basic characteristics. We continue with a discussion of the spectral types, evolution, and other properties of cooling white dwarfs, with an emphasis on the internal physics. We then introduce the pulsating white dwarfs and provide an updated view of their status. We finally discuss the impact (real and potential) of asteroseismology on our knowledge of degenerate stars.

Background and aim: radial shock wave therapy (RSWT) is a relatively new way to treat chronic tendinopathies, such as lateral epicondylitis. However, very few studies have been realized on this subject, and the results are very divergent. We aimed to observe the impact of this technique on chronic lateral elbow pain. Method: fifteen subjects who had a lateral epicondylitis for at least 3 months were included in the study. Two groups were formed: experimental (10 subjects) who received 6 sessions of physiotherapy and RSWT, and the control group (5 subjects) who received exclusively physiotherapy. Physiotherapy sessions were composed of massage, stretching, diacutaneous fibrolysis, and a muscular eccentric program of the wrist extensor muscles. We evaluated the subjects before the first session, and after 6 weeks of treatment with a pain visual analog scale (VAS), the painless wrist flexion amplitude, ant the “Patient-Rated Tennis Elbow Evaluation” (PRTEE) questionnaire. Results: the difference between initial and final evaluations was significant (regarding to the wilcoxon test) for all of the parameters studied (p=0,028 for the VAS, p=0,005 for the wrist flexion amplitude, and p=0,005 for the PRTEE) in the experimental group. It wasn’t significant in the control group (VAS p=0,144128, wrist flexion amplitude p=0,079617, and PRTEE p=0,067890). The comparison between the two groups was not significant, neither in the beginning, nor in the end of the treatment (regarding to the Umann and Whitney test) Conclusions: RSWT associated to physiotherapy is a more effective treatment for lateral epicondylitis than physiotherapy alone.

We observed an influence of the stallion on volume, spermatozoa concentration and all CASA parameters (p<0.0001), which are highly dependant on each other due to geometrical association of these data. That stallion effect may have interfered with the associations we observed as stallions seem to have specific concentration and motility pathways. More studies, with more replicates, will allow comparing results from a same stallion and further establish the correlations we report here. [less ▲]

Diagnosis of endometritis in the mare is routinely based on the presence of polymorphonuclear cells (PMNs) on endometrial smears. Studies show a relation between PMNs and myeloperoxidase (MPO), an enzyme released by PMNs during degranulation or after cell lysis, in many fluids and tissues. The aims of this study were to assess the presence and concentration of MPO in the mare’s uterus, and to investigate its relation with PMNs. Thirty-six cycles from 28 mares (ages ranging from 6 to 22 years) were used. Endometrial cytological samples were obtained with a small volume uterine flush and either a uterine cotton swab or a cytobrush, when a follicle >35 mm was observed by ultrasound. The smears were stained with Diff-QuickÒ and one or more PMNs per field (400·) was diagnosed as endometritis. The supernatant of the flushes was used to measure MPO concentration with a specific equine MPO ELISA assay. Our results showed the presence of MPO in the equine uterus during oestrus (mean = 2839 + 2785). MPO concentrations were signifi- cantly (p < 0.05) higher in samples with positive cytological results. Occasionally, some samples with negative cytological results showed high MPO concentration, but the opposite was never observed. Clinical signs of endometritis are not always present, or they may be delayed. An early diagnostic improves the success of treatment. Our results show that high quantities of MPO in endometrial samples indicate the presence of PMNs. Further studies are needed to determine if MPO concentration could be routinely used as a tool of early detection of endometritis. [less ▲]
