The objective of this research is to evaluate a Gaussian tilting plume model that takes into account the spray characteristics of agricultural nozzles to predict drift. The application of this type of model has proved to be effective for aerial pollution applications. To be applied successfully to the spray drift, the model has to give accurate predictions of the deposits regarding the spray and material characteristics as well as the weather parameters. To reach this objective, the model parameters must be correctly set based on appropriate theoretical basis and experimental data. Based on wind tunnel measurements, the effect of the most important characteristics of spray droplets from an agricultural nozzle has been modelled using a Gaussian tilting plume approach by discretizing the different droplet classes. Although the theoretical basis of the model is simple, the predicted drift appeared to be in relatively good agreement with the experimental results. The discrepancies could be explained by poor fitting of the dispersion model parameters. Further work is required to optimise the value of the model parameters. [less ▲]

Sugar beet leaves were used as source of lyase in a biocatalytic process for the production of C6-aldehydes. Their hydroperoxide lyase activity was revealed important. The optimum values of pH and temperature for reactions were respectively 6.7 and 22 °C. A simple and fast process providing high molar conversion of hydroperoxides to aldehydes is proposed. The yield of the main product cis-3-hexenal reached 80% after only 2 min and was stabilised by acidifying the reaction medium to pH 2. [less ▲]

Isomaltooligosaccharides (IMOs) are non-digestible oligosaccharides, considered as prebiotics and therefore aim to selectively feed probiotics indigenous to the human colon. Recent data obtained in human subjects, support the involvement of dietary oligosaccharides in physiological processes in the different intestinal cell type and also outside the gastrointestinal tract (e.g. hormone production, lipid and carbohydrate metabolism). IMOs consists of glucose monomers linked by at least one α-1-6, or in a lower proportion α -1-3 (nigerose family) or α -1-2 (kojibiose family) glucosidic linkages. In our case they are produced enzymatically from corn starch. It results in a very complex mixture with molecules characterized at the same time by their DP value (from 2 to ~20), linkages types (α-1-2, 3 or 6) and the proportion and position of each type of linkage (only α -1-6 or combined types). The challenge of this study was to find a qualitative and quantitative method to characterize the syrups. In a subsequent study, every unidentified peak could be determined by NMR or Mass spectrometry. Three different chromatographic methods have been tested and compared over their selectivity, sensibility, robustness, applicability and their quantitative power. [less ▲]

The communication presents the various requirements imposed to electronic nose to become an instrument of environmental monitoring. Obstacles of the monitoring of real life environmental odours may be classified into three categories: • the final goal of the study, requiring to measure a global odour annoyance and not any gaseous emission, • the analysed sample itself, which is highly variable, due to the process evolution and to the influence of ambient parameters; • and the operating conditions, needing to work far from any building and sometimes at locations not easy to reach. The paper suggests some simple solutions to those problems. [less ▲]

Unité de Neuropsychologie, Université de Liège (Belgique) Introduction Le trouble d’attention avec hyperactivité (ou ADHD, Attention Deficit/Hyperactivity Disorder) se caractérise par [1] un trouble d’attention, [2] une importante agitation motrice et [3] une impulsivité motrice. Ce trouble présente une prévalence estimée à 5 à 10% de la population prépubère, avec une nette prédominance masculine. Les conséquences de l’ADHD sont importantes : échec scolaire, difficultés d’apprentissages, mauvaise intégration sociale… En neuropsychologie, l’approche de l’ADHD vise à mieux comprendre les difficultés cognitives – et en particulier exécutives – que présentent ces enfants. Ainsi, s’il apparaît qu’un grand nombre de processus exécutifs sont altérés (voir Willcutt et al., 2005), plusieurs auteurs soulignent qu’un déficit de l’inhibition constituerait l’élément-clé qui rendrait compte des manifestations cognitives et cliniques de ce syndrome (Barkley, 1997). De nombreuses recherches ont toutefois suggéré que l’inhibition ne renvoie pas à un processus unitaire mais implique au contraire plusieurs sous-composants (inhibition verbale, motrice, perceptive ; voir par exemple Nassauer & Halperin, 2003). L’objectif de cette étude consiste à déterminer dans quelle mesure les troubles de l’inhibition présentés par les enfants ADHD sont sous-tendus par un déficit généralisé des processus inhibiteurs ou au contraire par une atteinte spécifique d’un de ces processus. Méthode Nous avons administré à 13 enfants ADHD âgé de 6 à 12 ans et 13 enfants de contrôle (appariés sur base de l’âge et du sexe) des tâches d’inhibition évaluant les capacités d’inhibition verbale (test de Stroop), motrice (épreuves de la Statue et du Go/No Go) et perceptive (Nassauer & Halperin, 2003), et une épreuve de raisonnement (Matrices de Raven Colorées). Résultats Les analyses de comparaison de moyennes indiquent que les enfants ADHD présentent des performances inférieures à celles des enfants de contrôle pour l’ensemble des épreuves d’inhibition : inhibition verbale (p<.05), motrice (p<.001) et perceptive (p<.01). Toutefois, des analyses de covariance montrent que lorsque l’on contrôle le niveau de raisonnement, les différences entre nos deux groupes disparaissent pour toutes les tâches, à l’exception de l’épreuve d’inhibition motrice « Statue ». Discussion Ces résultats préliminaires suggèrent que les enfants ADHD ne présentent pas un déficit généralisé des processus inhibiteurs, et que les troubles de l’inhibition motrice constituent probablement un élément-clé caractérisant le profil cognitif de ces enfants. Ces données confirment par ailleurs l’idée selon laquelle le concept d’inhibition recouvre des processus différents susceptibles d’être affectés de façon spécifique dans l’ADHD. [less ▲]

Introduction : An oxidant activity has been implicated in the onset of equine osteoarthritis. Most of the studies have been done on articular chondrocytes, but little is known about the role of synoviocytes. Objective : Our aim was to investigate if equine articular chondrocytes, primary synoviocytes or synoviocytes of a continuous cell line are able to produce free radicals after exposure to anoxia and re-oxygenation. Methods : By oxymetry and electron paramagnetic resonance (EPR), we investigated the effects of repeated anoxia/re-oxygenation (A/R) periods on the respiration and production of free radicals by synoviocytes (rabbit HIG-82 cell line and primary equine synoviocytes) and equine articular chondrocytes. Three periods of 20 min anoxia followed by re-oxygenation were applied to 10exp7 cells; O2 consumption was measured before anoxia and after each re-oxygenation. After the last A/R, cellular free radical formation was investigated by EPR spectroscopy with spin trapping technique (n = 3 for each cell line). Results : Both types of synoviocytes showed a high O2 consumption, which was slower after anoxia. By EPR with the spin trap POBN, we proved a free radical formation. Results were similar for equine and rabbit synoviocytes. For chondrocytes, we observed a low O2 consumption, unchanged by anoxia, and no free radical production. Conclusion : These observations suggest an oxidant activity of synoviocytes, potentially important for the onset of osteoarthritis. [less ▲]

Aims As part of the promotion of a national strategy for the prevention and the management of acute and chronic low back pain (CLBP), the Belgian Health Care Knowledge Centre (KCE) funded a systematic review of the EBM literature concerning the management of LBP patients in the occupational health (OH) context. Taking account differences in regulations and practices within the health care system between EU countries1,2, this review aimed at issuing good practices recommendations applicable to the Belgian situation to prevent the transition from acute to chronic back pain and to avoid long duration absences from work. Methods The guidelines have been developed in three steps. First, an electronic search was performed for relevant guidelines and systematic reviews (SR) on the following databases: EMBASE, Medline, Cochrane Controlled Trials Register, NHS guidelines Finder, National Guidelines Clearing House, New Zealand Guidelines Group Search and Pedro database. The search strategy combined 3 groups of terms: low back pain, occupational medicine and the type of reference (practice guideline or SR). The identified guidelines were appraised using the AGREE method, while SR’s were appraised using the Cochrane Collaboration grid. In a second phase, the draft guidelines were submitted to a group of OH academics from the main Belgian universities. The revised version of the guidelines was then published in English in the KCE report 3. In a third step currently under way, the guidelines are adapted in a more practical format for facilitating their daily use by OH practitioners. This involves a working group of OH practitioners coming from 12 external prevention services and several large company OH services. The document will also be discussed with representatives of other health professionals (GP’s and medical advisors of the sickness funds). Results Scientific evidence from the 7 selected guidelines and from the 27 SR’s was organized according to the main missions of the occupational physician (OP) and medical adviser (MA). Which background information should be given to employers and employees when the OP is playing an adviser role? What evidence-based prevention policies (primary and secondary) should he/she promote in the enterprises? For the third mission of the OP, health surveillance of workers, the document considers three situations: periodic health surveillance, spontaneous examinations at the worker request, and return to work (RTW) examinations for workers absent for 28 days or more. The main conclusions are summarized in 4 tables under the format of key-points, each of those mentioning the quality of the evidence (using the Guyatt classification). Discussion and conclusions The key message for prevention of CLBP is the need for staying active and minimizing the time out of work. Evidence of high quality is in favor of a multidisciplinary approach using conservative treatments. One challenge is to avoid hospitalizations and especially surgery in CLBP patients. Those recommendations are relevant for all care settings, including the occupational environment. From a health care policy point of view, the project highlighted the major roles of the occupational physician and of the medical adviser and stressed the need to better define those roles if decision makers want to tackle the low back pain problem and the economic consequences of the related sick leave.

Durant la saison hydrologique 2006-2007, le transport solide par charriage a été étudié dans un affluent de la Lienne (la Chavanne). Ce ruisseau ardennais, a été équipé d’un limnigraphe et d’un piège à sédiments. Ce piège consiste en deux fosses rectangulaires, perpendiculaires au sens d’écoulement, d’une capacité de piégeage de 2 m³. Les paramètres de mobilisation (puissances spécifiques, tensions de cisaillement) ont été déterminés pour des crues de différente importance et ont été mis en relation avec la taille des éléments piégés. L’analyse des caractéristiques sédimentologiques des galets piégés a permis de mettre en évidence l’influence de l’aplatissement sur la mise en mouvement des galets de différentes lithologies et d’affiner les valeurs du critère adimensionnel de Shields en condition naturelle. Par ailleurs, les galets piégés ont été comparés avec les scories présentes dans la charge de fond. Ces éléments, produits au XIVe siècle par un haut fourneau implanté 700 m en amont du site d’étude, constituent un indicateur de la compétence effective de ce cours d’eau sur une période de plusieurs siècles. La quantité de sédiments charriés a été mesurée par curage des fosses de manière systématique après chaque crue mobilisatrice. Dans cette rivière, le débit solide par charriage est seulement de 0,4 t.km-2.an-1, malgré la fréquence élevée du débit de mobilisation. Cette valeur est relativement faible vis-à-vis de ce qui a été mis en évidence sur d’autres cours d’eau ardennais plus importants (Houbrechts et al., 2006), où des valeurs 2,5 t.km-2.an-1 peuvent être atteintes.

Growth phases are observed to start from less than 30 minutes to over an hour before the substorm onset. The sector of maximum proton precipitation during the growth phase is generally located around 2200 MLT. It rapidly moves in local time by about 1.2 hour toward midnight at the time of the onset. The open magnetic flux increases by as much as a 33% during the growth phase. The mean value of the open flux at the end of the growth phase, immediately preceding the substorm, onset is about 0.74. GWb for substorms triggered by external (solar wind) factors and 0.67 GWb for non-triggered substorms. The open magnetic flux generally drops following the onset of triggered substorms but continues to increase for non-triggered events. We interpret this behavior as an indication that the rate of opening of closed field lines on the dayside can exceed that of the nightside reconnection after the onset in non-triggered substorms. By contrast, flux closure is more efficient while the flux opening rate drops in the case of externally triggered onset, so that the closure rate exceeds that of field line opening on the dayside. The rate of equatorward displacement is typically ~ 3 deg/hour. It is statistically correlated with the magnitude of the southward Bz component of the IMF measured by the ACE satellite. It is also correlated with transfer functions describing the efficiency of solar wind energy transfer which involve the transverse electric field carried by the solar wind. The equatorward motion may be global, restricted to local time sectors or a combination of both. No nightside local time sector appears favored where the motion of the equatorial boundary would be more pronounced. The maximum displacement of the polar boundary is statistically located around midnight MLT. [less ▲]

Facultative paedomorphis is a developmental process in which larvae opt for metamorphosis before maturity or reach sexual maturity while retaining larval traits (e.g., gills). Although metamorphosis is not reversible, the paedomorphic state is not a dead end as branchiate adults are able to metamorphose. However, the extent of this process has never been quantified in the wild. Our aim was then to estimate switching rate by carrying out a 3-year monitoring survey of a population of Alpine newts (Triturus alpestris) inhabiting an alpine lake. The data were analysed using a multi-state capture-recapture model. While morph switching did occur in this population, it involved only 12% of the paedomorphs each year (i.e., 17% of recaptured individuals), suggesting that metamorphosis was not favoured in this population during the study period. This rate is lower than in laboratory experiments during which newts from the same population were placed in water drying conditions, but as shown previously paedomorphs can avoid metamorphosis in migrating to permanent water bodies when their pond dries out. These results are in agreement with other studies showing an advantage of a dimorphism in heterogeneous habitats. The ontogenetic pathway of wild Alpine newts is thus characterised by two forks in the developmental pathway. The first occurs during the larval stage, and the second occurs in paedomorphic adults. Such a two-level decision process may allow individuals to cope with environmental uncertainty. This may be particularly adaptive as aquatic conditions can deteriorate over time as shown by yearly changes in body condition of newts [less ▲]

Ecological thresholds are defined as points at which a rapid change occurs from one ecological condition to another. Their determination in species–habitat relationships has important implications because they allow to understand ecological requirements of species and to provide efficient conservation measures. However, there is a lack of concordance across studies and this method was not yet applied to newts. In this study, we sampled 371 ponds to gather occurrence data on the palmate newt Triturus heveticus and the Alpine newt Triturus alpestris. We tested for the existence of significant thresholds for three variables: distance to forest, forest and crop covers. We found significant thresholds for both landscape configuration and composition, with relationships between distance to forest and occurrence of Triturus alpestris and T. helveticus, and forest and crop cover and T. helveticus. Both species require breeding ponds within a given distance from the forest, but T. helveticus is more dependent on forest availability than T. alpestris: its ecological threshold is located at lower distance from forest edge, and requires also higher values of forest cover. Crops have a negative influence on palmate newt distribution with a significant breaking point, but not for T. alpestris in the studied area. These results indicate that thresholds can be a useful concept from which tools may be developed. They are particularly pertinent to focus conservation effort for threatened species and their habitats as quantitative measures of the most required habitats for species can be obtained from statistically determined breaking points [less ▲]

The interesterification, or ester exchange, between two fats leads to the rearrangement of acyl moieties in both. The use of a sn-1,3-specific lipase confines the exchange of fatty acid residues to the sn-1 and sn-3 positions of triacylglycerides (TAG), generating products with characteristics that cannot be obtained through a chemical process or a blending. Such reactions require mild conditions with no solvent needed and they yield no unhealthful trans fatty acids, justifying the stepped-up interest of enzymatic interesterification for the production of margarines and other food fats. The aim of this work was to use enzymatic interesterification to enrich anhydrous milk fat (AMF) with unsaturated fatty acid C18 residues from linseed oil (LO) and eventually from rapeseed oil (RO) through some binary blends and one ternary blend. For that, the 1,3-specific lipase from Thermomyces lanuginosa (Lipozyme TL IM) was used in solvent-free batch and micro-aqueous reactions and fat blends with different mass ratios were tested. The evolution of TAG profiles, of interesterification degre (ID) and of free fatty acids (FFA), was followed along the reactions. Determination of dropping points (DP) and solid fat contents (SFC) enabled a rheological characterization of the products. The end products were also characterized for their oxidative stability and their textural properties. [less ▲]

Automated image analysis of particles under controlled orientation (SIA) is becoming a challenging technique for laser diffraction (LD) in the field of sizing metallic particles above 5 μm. Thanks to optimal particle dispersion and fully automated microscopic imaging, it is now possible to gather individual measurements on thousands of particles within a minute. The aim of this paper is to compare results obtained with both image analysis and laser diffraction from a selection of powders (figure 1) in the range between 5 μm and 250 μm. [less ▲]
